Elaborazione e cambio linguistico: considerazioni sulle ‘lingue minori’ sull’esempio della scritturalità friulana

Abstract Since Friulian has been recognized as a minority language by the region Friuli-Venezia Giulia (1996) and by the Italian Republic (Law 482/1999), the elaboration process has been accelerated and intensified. Friulian has advanced into text types in which it had not been used before, such as scientific papers, administrative texts, journal articles, etc. In order to fulfill the needs of these new communicative purposes, an extensive and intensive elaboration of language is needed. This happens on the one side through a conscious codification process, especially by intense lexicographical activity, and on the other side “by doing”. In both cases, the influence of more elaborated languages – mainly of Italian, but partially also of other languages, especially English – plays a central role. Lexical items, but also morphological processes and syntactical structures are borrowed from these languages. This fact has structural consequences on Friulian, and, in the long run, could cause a typological change. After a brief outline of the recent history of the elaboration of Friulian and its legal framework, I will focus on some morphological and syntactical structures: the formation of relational (denominal) adjectives instead of prepositional phrases (which also triggers some less productive morphophonological patterns) and the borrowing of Italian adjectives and nouns derived from a present participle, provoking Friulian loan formations, although in Friulian present participles are no usual grammatical structures. In the end, I will focus on stâ+gerund periphrases, which are built on the Italian model. These are compatible with some aktionsart verb classes that the ‘genuine’ Friulian aspectual periphrases jessi che+indicative present or imperfect and jessi daûr a+infinitive cannot be used with and therefore it can be seen as a change in the semantic-syntactic system of Friulian.

Microbialites on the northern shelf of Lake Van, eastern Türkiye#: Morphology, texture, stable isotope geochemistry and age

ABSTRACTLake Van, the world's largest alkaline lake, hosts some of the largest microbialite towers worldwide, which are considered as modern analogues of ancient stromatolites. This study investigates the links between microbialite evolution, geology, climate and hydrology, and the role of biotic and abiotic processes in microbialite growth and morphology. For these objectives, the northern shelf of Lake Van was surveyed by sub‐bottom seismic profiling and diving, and two 9 m and 15 m high microbialite chimneys were sampled at 25 m water depth. Samples were analysed for stable oxygen and carbon isotopes, X‐ray diffractometry, scanning electron microscopy and U/Th age dating. Lake Van microbialites precipitate wherever focused Ca‐rich groundwater flows onto the lake floor to mix with alkaline lake water. Variable columnar, conical and branching morphologies of the microbialites indicate various processes of formation by groundwater channelling within the chimneys. Collectively, our data suggest that the microbialite chimneys have formed within the last millennium, most likely starting during the warm and humid Medieval Climate Anomaly (ca ad 800–1300), when lake level rose approximately to the present level due to enhanced Inputs of riverine Ca‐rich freshwater and groundwater. Our new scanning electron microscopy observations indicate that the internal structure of the microbialites below the outer cyanobacteria‐covered crust is constructed by calcified filaments, globular aggregates and nanocrystals of algal, cyanobacterial and heterobacterial origins and inorganically precipitated prismatic calcite crystals. These textural features, together with dive observations, clearly demonstrate the important role of inorganic carbonate precipitation at sites of groundwater discharge, followed by cyanobacteria and algal mucilage deposition and microbially meditated calcification in the photic zone in the rapid growth of the microbialite chimneys. Considering the close similarities of some textures with those of ancient stromatolites and meteorites, the results of this study provide new insights into the environmental conditions associated with stromatolite formation and extra‐terrestrial life evolution.

Morphological processes of Balish

Balinese English which is in this article called Balish has an important role in the world of tourism, namely as one of the most important capital for workers in the field of tourism, and they use Balish. Tourism workers are classified as lower class such as merchants, masseurs, parking attendants, shop assistants or kiosks, etc. Balish lexicon has gone through morphological processes. These are the proofs that linguistics has been affected, particularly in the field of morphology. Therefore, this article aims to find Balish lexicon along with their morphological processes. The data were taken from tourism workers at Ubud and Tanah Lot. Documentation method and note-taking technique were applied in collecting the data. Yule’s theory of word formation (2020) and morphological processes theory from O’Grady & Archibald (2016) were applied in analyzing the data through descriptive-qualitative method. The results of the research show that there are 12 types of morphological processes found, namely compounding, blending, borrowing, clipping, conversion, initialism, acronym, inflection and derivation, coinage, and multiple processes. The research proves that morphological process is still relevant and has always been the fundamental base in the formation of new lexemes in a constantly advancing world.

Far-red Photons Increase Light Capture but Have Lower Photosynthetic Capacity Than Red Photons

Far-red photons (700–750 nm) can accelerate crop growth during indoor production through both physiological and morphological processes. A previous study showed that far-red photons can drive photosynthesis with efficiency similar to that of traditionally defined photosynthetically active photons (400–700 nm) if they are provided together with shorter-wavelength photons. Far-red photons also promote leaf and canopy expansion, which can increase light interception and growth. This study aimed to distinguish the contribution of morphological and physiological changes to crop growth induced by substituting red photons with far-red photons. We studied the long-term effects of substituting red photons with far-red photons on canopy light interception and whole-plant photosynthesis. ‘Little Gem’ lettuce (Lactuca sativa) seedlings were grown under four light spectrums of the same total photon flux density (400–750 nm). In addition to a background of a mixture of white and blue photons of 150 μmol⋅m−2⋅s−1, we provided 51 μmol⋅m−2⋅s−1 red photons, far-red photons, or mixtures of red and far-red photons. In the first run, plants were harvested twice. The first harvest was at canopy closure, and the second harvest was when plants reached full size. In the second run, we harvested lettuce plants more frequently to minimize leaf overlap and interplant competition. We found that far-red photon substitution promoted leaf and canopy expansion and increased light interception. The effect of far-red photon substitution on leaf and canopy expansion was stronger in the second run than in the first run, likely because of lower plant density in the second run when plants were harvested more frequently. Far-red photon substitution of red photons decreased the amount of extended photosynthetically active radiation (ePAR) photons (400–750 nm) absorbed by leaves because of the lower leaf absorptance of far-red photons. The greater effect on canopy expansion in the second run of far-red photons substitution was able to exceed the reduction of ePAR photon absorption by leaves; therefore, we observed an increased crop gross photosynthetic rate (Pg) between the second and third harvests during the second run. However, during the first run, lower absorptance of ePAR completely offset the effect of the greater canopy size and light interception, and crop Pg was decreased in the first run before the first harvest. The changes in light interception and crop Pg resulting from far-red photon substitution did not affect dry weight. Far-red photons had photosynthetic activity when applied with a blue and white light mixture, but their efficiency was approximately half that of red photons, potentially because of the lower absorptance of far-red photons. In conclusion, far-red photon substitution of red photons increased canopy size but decreased ePAR photons absorbed by leaves and did not increase the final dry weight. Because far-red light-emitting diodes (LEDs) have higher efficacy for converting electricity into photons, including far-red LEDs in fixtures for sole-source lighting can reduce energy costs without decreasing lettuce yields.

The Role of Silver Nanoparticles in Response of In Vitro Boysenberry Plants to Drought Stress

Drought is one of the leading abiotic factors limiting morphological and physiological activities in blackberry cultivation. In this study, the effects of silver nanoparticles (AgNPs) on some morphological and biochemical processes in boysenberry (Rubus ursinus Chamisso and Schlenhtendal) under drought stress were investigated. The experiment was performed with three drought stress levels simulated with Polyethylene Glycol (PEG) (0, 4, 8%) and three AgNP treatments (0, 0.1, 0.2 mg L−1) in vitro conditions. Drought stress reduced root and shoot development of boysenberry plants grown in vitro. The addition of AgNPs significantly alleviated the adverse effect of drought stress and increased the plant growth parameters. Antioxidant activity of superoxide dismutase (SOD) and catalase (CAT) enzymes increased in boysenberry leaves when treated with AgNPs under drought conditions, while the amount of malondialdehyde (MDA) decreased. As a result of the study, 0.1 mg L−1 AgNPs is recommended as the most effective dose to promote the growth and development of in vitro boysenberry plants under drought stress.

The Birth and Death of Affixes and Other Morphological Processes in English Derivation

Linguistic change in morphology is usually discussed mainly in relation to change in inflectional morphology. In this paper, the focus is shifted to derivational morphology, where the issues are not entirely the same. In particular, the origins (or birth) of affixes and the loss (death) of affixes are central to the present discussion, with formal, semantic and pragmatic factors all having a role to play. The question is also raised as to whether it is, in principle, possible to tell that any affix is completely dead.

Hydromorphological index for rivers as an indicator of land use impact on watercourses in southern Poland

Study regionSouthern Poland Study focusLand use has a significant impact on hydrological and morphological processes in river basins. Hydromorphology, combining these processes, plays a key role in the proper functioning of aquatic ecosystems. This paper presents the results of an analysis of hydromorphological conditions for 77 sections designated on 39 watercourses related to semi-natural, agricultural, and urbanised land use. The study was carried out using the Hydromorphological Index for Rivers (HIR) method. Two components of the HIR were analysed: the Hydromorphological Diversity Score (HDS) and the Hydromorphological Modification Score (HMS). New hydrological insights for the regionAs studies show, the HIR Index can be successfully used as an indicator of the impact of land use on watercourses. There are significant differences in HIR between land use groups. The highest HIR values were recorded in semi-natural sections, while the lowest values were recorded in urbanised sections. In the studied region relatively high hydromorphological diversity was observed. It is also noticeable that the physical attributes of the channel correlate most frequently with the research sections in agricultural area. It has also been shown that hydromorphological diversity, apart from land use, is influenced by altitude, catchment size and geological type. This is an indication for decision-makers in the field of water policy that the proper land use plan in the catchment should be approached comprehensively.

English derived word recognition by Chinese‐English bilinguals: Testing the nature and time course of the component processes

ABSTRACT Research utilizing morphological priming has found that L2 speakers show facilitation from derived L2 primes, which could suggest morphological processing during derived L2 word recognition. However, the process of L2 derived word recognition is still poorly understood, with some arguing that the observed priming effects may not be morphological in nature. The present study is a partial replication of Rastle et al. and its extension to L2 English processing. Its purpose is to contribute to our understanding of the nature and time course of L2 derived word recognition. Following Rastle et al., I employed visual priming methodology to explore the activation of morphological, pseudomorphological, orthographic, and semantic processes during a later, central-lexical stage of L2 English derived word recognition by Mandarin Chinese-English bilinguals. The results replicated Rastle et al.’s findings with L1 English speakers. The L2 speakers exhibited morphological effects distinguishable from effects of form overlap, suggesting that surface form overlap cannot explain L2 facilitation from derived primes. These same L2 speakers further showed pseudomorphological facilitation distinguishable from surface form effects, indicative of the operation of a purely morpho-orthographic process at the later stage of L2 English word recognition and further suggesting L2 sensitivity to morphemic structure that cannot be explained by semantic effects. Results further showed a similar graded pattern of activation of morphological, pseudomorphological, and form mechanisms in L2 and L1 speakers of English that appears to be temporally shifted between the two speaker populations. Implications for L2 word recognition theory are discussed.

Morphology and Depositional Processes of a Carbonate-Filled Canyon in the Carboniferous KT-II Formation of the Eastern Precaspian Basin, Kazakhstan: Insight from 3D Seismic Data

Canyons in carbonate depositional settings, as important elements of the source-to-sink system, remain poorly studied compared to those in siliciclastic depositional environments. The latest high-resolution three-dimensional seismic data, well logs, and core data at the eastern edge of the Precaspian Basin are used to investigate the geomorphology, infillings, and depositional process of a unique carbonate-filled canyon in the Carboniferous KT-II formation parallel to the carbonate platform, which is distinct from other slope-perpendicular canyons. The canyon has a total length of more than 52.3 km with a nearly N-S orientation and an S-shaped geometry, and the whole canyon can be divided into three segments by two knickpoints. The slope-parallel orientation of the canyon is mainly controlled by the palaeogeomorphology and reverse faults. Due to the collision of the Kazakh and European plates in the early-middle Visean (early Carboniferous), the canyon was formed in a northern tilted, elongated, and restricted palaeotopographic feature between uplifts. The development of reverse faults related to tectonic movement controlled the variations in the width of the canyon and the positions of the knickpoints. Tectonics controlled the orientation and formation of the canyon, while sedimentary processes contributed to its infilling. The well-seismic tie analysis indicated two distinct periods of the canyon fillings, Ss1 and Ss2, which were separated by a second-order sequence boundary. The lower part contained sediments supplied by both sides of the canyon through channels or gullies, and the upper part was dominated by a carbonate platform that prograded from the eastern side of the canyon. The evolution of the canyon can be subdivided into three stages. The increasing stage was mainly characterized by significant upslope erosion through headward retrogressive mass failures in the slope-parallel confined negative relief to form the canyon during the lowstand system tract of Ss1. Subsequently, in the early filling stage, the carbonate factory was productive during the highstand, and massive excess carbonate sediments were transported into the adjacent canyon by channels or gullies on both sides and deposited. The canyon was basically filled, and the morphology became much gentler. During the subsequent late filling stage, the carbonate platform was flooded again during the highstand, and the production rates of the carbonate factory greatly increased. The lateral progradation of carbonate platforms accelerated on the canyon of the early filling stage and further into the inner sag.

Modulation of Methacrylated Hyaluronic Acid Hydrogels Enables Their Use as 3D Cultured Model.

Bioengineered hydrogels represent physiologically relevant platforms for cell behaviour studies in the tissue engineering and regenerative medicine fields, as well as in in vitro disease models. Hyaluronic acid (HA) is an ideal platform since it is a natural biocompatible polymer that is widely used to study cellular crosstalk, cell adhesion and cell proliferation, and is one of the major components of the extracellular matrix (ECM). We synthesised chemically modified HA with photo-crosslinkable methacrylated groups (HA-MA) in aqueous solutions and in strictly monitored pH and temperature conditions to obtain hydrogels with controlled bulk properties. The physical and chemical properties of the different HA-MA hydrogels were investigated via rheological studies, mechanical testing and scanning electron microscopy (SEM) imaging, which allowed us to determine the optimal biomechanical properties and develop a biocompatible scaffold. The morphological evolution processes and proliferation rates of glioblastoma cells (U251-MG) cultured on HA-MA surfaces were evaluated by comparing 2D structures with 3D structures, showing that the change in dimensionality impacted cell functions and interactions. The cell viability assays and evaluation of mitochondrial metabolism showed that the hydrogels did not interfere with cell survival. In addition, morphological studies provided evidence of cell-matrix interactions that promoted cell budding from the spheroids and the invasiveness in the surrounding environment.

The effect of zinc complex of N-isopropenylimidazole on the morphological characteristics of gum tissues in experimental endodontic-periodontal lesions in rats

Introduction: Combined inflammatory and destructive processes affecting the dental pulp and tissues of the periodontal complex are among the most problem diseases of the dental system. Current therapy with use of available pharmacological agents does not always allow achieving the expected positive result. In addition, often the lack of information about morphological processes in the tissues of the dental system, in particular the gums, with endodontic-periodontal lesion (EPL) limits the ability of dentists to carry out targeted pharmacotherapy with both traditional and, in particular, new medications. The aim of the study was to evaluate the morphological characteristics of gum tissues in a therapeutic context of N-isopropenylimidazole zinc complex derivative in experimental endodontic-periodontal lesion in rats. Materials and Methods: A simulation of EPL in rats was performed in two ways: simultaneous induction of acute periodontitis and parodontitis by pulp extraction and natural infection of the pulp cavity, as well as by ligation of the necks of lower incisors. The research protocols included 5 groups of animals: 1st – intact group (control-1); 2nd – animals with simulated EPL (control-2); 3rd – animals with simulated EPL and treated with Metrogyl Denta® gel (M-D); 4th – animals with simulated EPL and treated with N–isopropenylimidazole zinc complex derivative gel under the laboratory code Pilim-1; and 5th – animals with simulated EPL and treated with the combination of M-D + Pilim-1. The gum of the lower incisors was taken for morphological studies. Slides were stained with hematoxylin and eosin. Computer morphometry was performed using the ImageJ software. Results and Discussion: The substances M-D, Pilim-1 and, especially, the combination of M-D+Pilim-1 (against the background of chlorhexidine bigluconate used as oral rinse) for 14 days in rats with simulated EPL cause a significant improvement of the morphological structure of the gum with minimal residual dystrophy and sclerosis. The combination M-D + Pilim-1 led to a 1.3-time increase in epithelial thickness, and a 1.5-time decrease in acanthosis depth in comparison with M-D, while the number of capillaries and their diameter had no significant differences. Compared with Pilim-1, the epithelial thickness increased 1.5 times, and the acanthosis depth and the number of capillaries decreased 1.6 and 1.4 times, respectively, whereas the diameter of the capillaries did not change significantly. The pronounced protective effect of the combination M-D + Pilim-1 on the morphological structure of the gingival mucosa of rats with simulated EPL may be associated with antimicrobial, anti-inflammatory, regenerating, angioprotective and antioxidant properties of both M-D and Pilim-1 separately, and, possibly to a greater extent, of the combination M-D + Pilim-1. Conclusion: The substances M-D, Pilim-1 and, especially, the combination M-D + Pilim-1 (against the background of chlorhexidine bigluconate used as oral rinse) for 14 days in rats with simulated EPL have a protective effect on the epithelial structure and the connective tissue of the proper mucous plate, manifested in active normalization of pathological changes and significant restoration of their organotypic structure.

Examination of the metallization behaviour of an ABS surface

ABSTRACT The main scope of this work is the metallization of high density Acryonitrile Butadiene Styrene (ABS) surfaces for aerospace applications. Originality and main focused area of the study is to grasp the mechanism of physical properties of the surface and the effect of wet chemical processes on the surface of the ABS substrate. After surface sensitization and metallization with nano-sized ions, the polyurethane surface is metallized and nickel (Ni) coated with electroless and elecrolytic Ni plating processes. The ultimate goal of these advances is the production of composite lay-up tools for the production of primary and secondary composite aircraft parts from nanoscale to macro level. Composite lay-up tool requirements of the aerospace industry include a minimum thickness of 5 mm, acceptability of airtightness testing and reduced surface roughness. Results show that increasing current density adversely affects the surface morphology and metallization processes enhance the surface conductivity of the foam.

Bound productivity in stem-formation and categorial separation

This study argues that individually unproductive processes of morphology can be highly productive for certain other tasks in sequential productions when they occur in combination with certain other processes. Unlike the relevant literature, which generally treats -(y)I as a phonological piece of the agentive suffixation in Modern Turkish, -(y)ICI, the study argues that -(y)I in instances like kır-ı-cı (break-nominalizer-agentive) ‘breaker/offending, hurtful’, is a stem-formative, creating novel stems required for further operation, -CI. Importantly, the -(y)I nominalization, with no semantic motivation, provides numerous (bound) V-(y)I- forms which are unattested in isolation without further derivation. Thus, the recognition of such a stem-formative is crucial. It shows that (i) form, meaning, and categorial separateness is necessary, and (ii) bound derivations and bound productivity can constitute a good part of the grammar. The study supports the formal analyses via the experimental findings of a recent survey of the productivity of a group of paradigmatic nominalizations including -(y)I in Turkish, and concludes that stem-formative operations may output “preforms”, which are bound but productive derivatives fulfilling the formal conditions of forthcoming operations, and that semantics-free stem-formations may involve categorial modifications. This leads us to categorial separation and its possible autonomy in grammar.

Exploring perspectives on the approach for teaching ablaut principles to English L2 learners: a case study in South African secondary schools

Although regular and irregular verb morphological processes in the simple past are invaluable approaches for enhancing communication, the formation of irregular verbs, including the ablaut principles, suppletion principles, and backformation, for example, pose challenges to the majority of English second language (L2) learners. Also, most teachers experience difficulties in teaching ablaut principles to their learners. The irregular verb morphological processes in the simple past tense are a challenge to many. The present study aimed to explore teachers’ perspectives on the approach for teaching ablaut principles to L2 learners. A qualitative research approach with a case study design was espoused because it provides an in-depth understanding of a particular phenomenon. Four purposively sampled teachers were interviewed and observed when teaching Grade 8 English L2 learners at Dzindi Circuit, South Africa. A Delve Thematic Analysis Software Version 22.0 was utilised because it uses and codes, identifies, and summarises perceptions within interview transcripts. Preliminary investigation indicated that learners were incompetent in using the ablaut principles. After employing game-based teaching approaches, learners performed outstandingly. The study acclaims using the identified approaches in the teaching and learning of the ablaut principle in the simple past tense, and further research is encouraged on the current topic.

Study on the Reactivity Activation of Coal Gangue for Efficient Utilization.

In this study, the research aim is to enhance the activity index of activated coal gangue and study its activation mechanism. The activation process of coal gangue was optimized through orthogonal tests, and the Back-Propagation (BP) neural network model was improved using a genetic algorithm. With the effects of grinding duration, calcination temperature, and calcination duration, the morphological changes and phase transformation processes of coal gangue were studied at the micro and meso levels to clarify the activation mechanism. The results indicated that the effect of calcination temperature on the strength activity index of coal gangue was most significant, followed by grinding duration and calcination duration. The potential activity of coal gangue can be effectively stimulated through mechanical and thermal activation, and the content of potential active minerals in coal gangue powders was also increased. The activation process of coal gangue for the optimal scheme was obtained as grinding at 76 min first and thermal treatment at 54 min at 749 °C. As the thermal activation under 950 °C, some unstable external hydroxyls, and internal hydroxyls in kaolinite from coal gangue were removed, the AlⅥ-O octahedron was destroyed, and kaolinite was transformed into spatially disordered metakaolinite with very high activity.

Impact of climatic disturbances on the chemical compositions and metabolites of Salvia officinalis

Abstract Aromatic and medicinal plants in ecosystems are subject to various climatic disturbances that impact their morphological and physiological processes. Although plants have mechanisms to adapt to their climatic conditions, such as periods of drought and lack of precipitation, their metabolism is still affected. This study aimed to predict and evaluate the behavior of Salvia officinalis under climatic disturbances. Over a period of 4 years in a controlled environment, three treatments were applied to the plant: Treatment 1 with normal monthly average temperature and precipitation in the first year; Treatment 2 with a temperature increase of 5°C and a 50% reduction in water supply in the second year; and Treatment 3 with a temperature increase of 10°C and a 75% reduction in water supply in the fourth year. The results show that the percentage of primary metabolites, including nutritional values, changed with increasing temperature and decreasing precipitation. Treatment 1 had 7.13% protein, 6.21% carbohydrate, 1.35% lipid, and 4% dietary fiber, while Treatment 2 had 7.05% protein, 5.12% carbohydrate, 1.01% lipid, and 3.01% dietary fiber, and Treatment 3 had 6.86% protein, 3.02% carbohydrate, 0.52% lipid, and 2.34% dietary fiber. The mineral composition of the plant also changed with each treatment, with Mg decreasing from 10.02 to 8.55 to 0.05%, Fe decreasing from 8.18 to 8 to 7.62%, K decreasing from 5.55 to 5.05 to 4.02%, Mn decreasing from 5.54 to 5.11 to 3.48%, Ca decreasing from 4.65 to 2.75 to 1.23%, and P decreasing from 3.37 to 3.05 to 2.25%. Regarding secondary metabolites, the percentage of alkaloids, flavonoids, saponins, coumarins, tannins, and essential oil yield changed as well. Treatment 2 showed an increase in secondary metabolites, while Treatment 3 showed a decrease. Alkaloids increased from 9.56 to 13.68 to 11.3%, flavonoids increased from 7.53 to 13.48 to 10.49%, saponins increased from 5.23 to 7.44 to 6%, coumarins increased from 3.35 to 4.85 to 3.99%, tannins increased from 2.26 to 3.22 to 2.62%, and essential oil yield increased from 0.53 to 0.80 to 0.62%. Gas chromatography analysis revealed that the major compounds of the essential oils of Salvia officinalis, such as α-thujone, manool, β-caryophyllene, α-humulene, viridiflorol, 1,8-cineol, and camphor, were also modified by temperature and water stress.

Morphological evolution mechanism of copper-based azide during gas-solid azidation process: Experiment and thermodynamic analysis

Copper-based azide (CA) synthesized by in-situ gas-solid azidation and utilized as preferred material for miniaturized explosive systems has attracted extensive attention from researchers. This work aims to reveal the morphological evolution mechanism of CA during gas-solid azidation processes. The morphological evolution processes of CA under different reaction conditions were observed and corresponding reaction stages were divided by the characteristics of product morphology. The morphology of product islands possesses a significant impact on the final morphology. To further reveal the morphological evolution mechanism, the continuous product layer and product islands core-shell thermodynamic equilibrium models were derived and studied to explain experimental findings. The energy properties of Cu(111), CuN3(220), Cu(N3)2(110) surfaces and corresponding interfaces were studied by first principle calculation to perform the thermodynamic equilibrium analysis. Based on the calculation results, the equilibrium thermodynamics analysis of Cu-CuN3, Cu-Cu(N3)2 and CuN3-Cu(N3)2 core-shell systems were performed and the corresponding dependence was discussed. The reaction modes were divided into thermodynamic-dominated and kinetic-dominated modes based on the different orders of product generation and the results of thermodynamic equilibrium analysis. The morphological evolution mechanism was proposed based on thermodynamic analysis and different reaction modes, which provides a fundamental perspective to regulate CA morphology and enhance corresponding performance.

A systematic review of morphological models of salt marshes

Salt marshes are among the most important coastal wetlands and provide critical ecological services, including climate regulation, biodiversity maintenance, and blue carbon sequestration. However, most salt marshes worldwide are shrinking, owing to the effects of natural and human factors, such as climate change and artificial reclamation. Therefore, it is essential to understand the decline in the morphological processes of salt marshes, and accordingly, the likely evolution of these marshes, in order to enable measures to be taken to mitigate this decline. To this end, this study presented an extensive systematic review of the current state of morphological models and their application to salt marshes. The emergence of process-based (PB) and data-driven (DD) models has contributed to the development of morphological models. In morphodynamic simulations in PB models, multiple physical and biological factors (e.g., the hydrodynamics of water bodies, sediment erosion, sediment deposition, and vegetation type) have been considered. The systematic review revealed that PB models have been extended to a broader interdisciplinary field. Further, most DD models are based on remote sensing database for the prediction of morphological characteristics with latent uncertainty. Compared to DD models, PB models are more transparent but can be complex and require a lot of computational power. Therefore, to make up for the shortcomings of each model, future studies could couple PB with DD models that consider vegetation, microorganisms, and benthic animals together to simulate or predict the biogeomorphology of salt marsh systems. Nevertheless, this review found that there is a lack of unified metrics to evaluate model performance, so it is important to define clear objectives, use multiple metrics, compare multiple models, incorporate uncertainty, and involve experts in the field to provide guidance in the further study.

Emerging Trends in Fast MRI Using Deep-Learning Reconstruction on Undersampled k-Space Data: A Systematic Review.

Magnetic Resonance Imaging (MRI) is an essential medical imaging modality that provides excellent soft-tissue contrast and high-resolution images of the human body, allowing us to understand detailed information on morphology, structural integrity, and physiologic processes. However, MRI exams usually require lengthy acquisition times. Methods such as parallel MRI and Compressive Sensing (CS) have significantly reduced the MRI acquisition time by acquiring less data through undersampling k-space. The state-of-the-art of fast MRI has recently been redefined by integrating Deep Learning (DL) models with these undersampled approaches. This Systematic Literature Review (SLR) comprehensively analyzes deep MRI reconstruction models, emphasizing the key elements of recently proposed methods and highlighting their strengths and weaknesses. This SLR involves searching and selecting relevant studies from various databases, including Web of Science and Scopus, followed by a rigorous screening and data extraction process using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. It focuses on various techniques, such as residual learning, image representation using encoders and decoders, data-consistency layers, unrolled networks, learned activations, attention modules, plug-and-play priors, diffusion models, and Bayesian methods. This SLR also discusses the use of loss functions and training with adversarial networks to enhance deep MRI reconstruction methods. Moreover, we explore various MRI reconstruction applications, including non-Cartesian reconstruction, super-resolution, dynamic MRI, joint learning of reconstruction with coil sensitivity and sampling, quantitative mapping, and MR fingerprinting. This paper also addresses research questions, provides insights for future directions, and emphasizes robust generalization and artifact handling. Therefore, this SLR serves as a valuable resource for advancing fast MRI, guiding research and development efforts of MRI reconstruction for better image quality and faster data acquisition.

Examining the Differences between Neologisms and Spelling Errors on Social Media

Neologisms and spelling errors are common features of social media and have contributed immensely to easing information dissemination in today?s world. The advent of the internet has enabled linguistic advancement, linguistic oddities, and communication. As an evolving phenomenon, language grants its users the liberty to use it as it suits them to convey their varied messages. The global language monitor in Austin calculated that a neologism is created every 98 minutes, while a spelling error occurs in every five posts on social media. This paper aims to examine the differences between neologisms and spelling errors. This work's theoretical framework is anchored on-Mediated Communication, Geoffrey Leech?s theory of linguistic deviations, morphological processes of word formation, and Pitt Coder?s theory of Error Analysis. The paper retrieved its data from status updates and comments on various social media platforms. The findings indicate that neologisms are formed by morphological processes such as blending, clipping, shortening, semantic extension, and acronyms and abbreviations, while spelling errors are formed by erroneous patterns of addition, selection, and omission . The paper concludes that neologisms and spelling errors are distinctive linguistic entities. While some neologisms may have been accepted as dictionary entries, spelling errors are outright blunders and linguistic oddities. As such, they can never be accepted as standard forms of communication.
