A Novel Polarity Correction Method for Waveform Stacking Location of Microseismic Events

Microseismic events play a crucial role in mapping fault and fracture distributions in natural and induced earthquakes. Detecting and localizing microseismic events is challenging due to low signal-to-noise ratios (SNR). Waveform stacking (WS) imaging location is a practical approach for automatically detecting and localizing microseismic events, assuming that the traveltime-corrected seismic waveforms will stack and enhance coherently. However, coherent stack enhancement is susceptible to polarity reversal caused by the non-explosive components of the source mechanism, which can lead to an unfocused source image, making it difficult to retrieve the optimal location accurately. In this study, we propose a new polarity correction method to address this issue, based on the characteristic that the instantaneous phase difference between two seismic signals with opposite polarity is ±p. First, the Hilbert transform is applied to the original seismic record to obtain instantaneous amplitude A(t) and phase f(t). Then, a new signal is constructed by multiplying A(t) with cos[2f(t)]. The constructed signals for different receivers have the same polarity, thereby being used to refocus the source image. Furthermore, they preserve both positive and negative amplitudes, which contributes to noise suppression. Synthetic tests show that the proposed method can effectively achieve polarity correction and noise suppression, enabling a high-resolution source image. Application to real hydraulic fracturing data demonstrates that the proposed method can detect and locate more microseismic events at the fracturing depths, suggesting its effectiveness and potential advantage in microseismic data processing. Since the polarity correction is performed in the data domain without relying on specific receiver layouts, the method is computationally efficient and could be applied to real-time microseismic monitoring across various sites, including hydraulic fracturing and volcano monitoring.

Edible Coatings for Fish Preservation: Literature Data on Storage Temperature, Product Requirements, Antioxidant Activity, and Coating Performance-A Review.

Fresh fish is among the most nutritive foodstuffs, but it is also the most perishable one. Therefore, huge efforts have been made to find the most suitable tools to deliver fish of the highest quality to exigent consumers. Scientific studies help the industry to exploit the newest findings to scale up emerging industrial technologies. In this review article, the focus is on the latest scientific findings on edible films used for fish coatings and storage. Since today's packaging processing and economy are governed by sustainability, naturality underpins packaging science. The synthesis of edible coatings, their components, processing advantages, and disadvantages are outlined with respect to the preservation requirements for sensitive fish. The requirements of coating properties are underlined for specific scenarios distinguishing cold and freezing conditions. This review raises the importance of antioxidants and their role in fish storage and preservation. A summary of their impact on physical, chemical, microbiological, and sensory alterations upon application in real fish is given. Studies on their influence on product stability, including pro-oxidant activity and the prevention of the autolysis of fish muscle, are given. Examples of lipid oxidation and its inhibition by the antioxidants embedded in edible coatings are given together with the relationship to the development of off-odors and other unwanted impacts. This review selects the most significant and valuable work performed in the past decade in the field of edible coatings whose development is on the global rise and adheres to food waste and sustainable development goals 2 (zero hunger), 3 (good health and well-being), and 12 (responsible consumption and production).

Is there a multilingual advantage in gender agreement processing? Evidence from self-paced reading

ABSTRACT Do learners who have mastered two gender systems prior to learning a third have an advantage in gender processing over those who have mastered only one gender system? To address this question, we recruited two groups of adult Polish learners of L3/Ln Swedish with and without prior knowledge of German. They completed a self-paced reading task in Swedish that involved two types of gender marking: the indefinite article, which is realised similarly in Swedish and German, and the definite suffix, which is uniquely present in Swedish. We found that while both groups were sensitive to gender agreement violations involving the indefinite article, only learners with knowledge of German showed sensitivity to gender agreement violations involving the definite suffix. Therefore, knowledge of non-native German conferred an advantage for the processing of dissimilar rather than similar gender marking. We interpret these findings in light of morphological transfer from German that consists in the employment of the existing morphemes and assigning them new grammatical functions. More broadly, the study indicates that the gender system in a non-native language rather than the native language, might be more helpful for the acquisition of a new type of gender marking in L3/Ln.

Tuning Molten-Salt-Mediated Calcination in Promoting Single-Crystal Synthesis of Ni-Rich LiNixMnyCozO2 Cathode Materials

High Ni-content LiNixMnyCozO2 (NMC) cathodes (with x ≥ 0.8, x + y + z = 1) have gained attention recently for their high energy density in electric vehicle (EV) Li-ion batteries. However, Ni-rich cathodes pose challenges in capacity retention due to inherent structural and surface redox instabilities. One promising strategy is to make the Ni-rich NMC material in the form of single-crystal micron-sized particles, as they resist intergranular and surface degradation during cycling. Among various methods to synthesize single-crystal NMC (SC-NMC) particles, molten-salt-assisted calcination offers distinct processing advantages but at present, is not yet optimized or mechanistically clarified to yield the desired control over crystal growth and morphology. In this project, molten-salt-mediated transformation of Ni0.85Mn0.05Co0.15(OH)2 precursor (P-NMC) particles to LiNi0.85Mn0.05Co0.15O2 particles is investigated in terms of the crystal growth mechanism and its electrochemical response. Unlike previous studies that involved large volumes of molten salt, using a smaller volume of molten KCl is found to result in larger primary particles with improved cycling performance achieved via partial reactive dissolution and heterogeneous nucleation growth, suggesting that the ratio of molten salt volume to NMC mass is an important parameter in the synthesis of single-crystal Ni-rich NMC materials.

Analysis of Gender and Mental Health Differences

With the rapid development of modern civilization, the increasing pressures of contemporary life, the fast pace of living, and the influence of social media, an increasing number of people are suffering from mental health issues. Mental health is an important aspect that everyone should be concerned about. Research has revealed that depression can significantly impact a person's professional and interpersonal skills, potentially affecting ones career trajectory. However, while both men and women face mental health issues, gender differences persist. Numerous studies have indicated that disparities exist in both brain structure and function between males and females. For instance, females may exhibit a greater advantage in emotional processing and social cognition, whereas males may demonstrate enhanced spatial cognition abilities. This study aims to explore gender differences in mental health across four factors. The result shows that, family intergenerational relationships have a greater impact on girls than boys. During their student years, interpersonal relationships within dormitories have a greater influence on boys. In the social sphere, women are more prone to depression than men. From a personal perspective, females are also more likely to experience negative emotions compared to males.

How does lexical coverage affect the processing of L2 texts?

Abstract Lexical coverage, i.e. the extent to which words in a text are known, is considered an important predictor of reading comprehension, with studies suggesting 98% lexical coverage leads to adequate comprehension. However, no studies to date have examined how the various lexical coverage percentages suggested in the literature are reflected by the cognitive effort involved in processing text and the attention that is devoted to the unknown vocabulary. This study used eye-tracking to examine how lexical coverage affects the processing of text (global measures) and unknown vocabulary (word-level measures), as well as the relationship between processing time on unknown vocabulary and learning. Advanced L2 learners of English read a text in one of four lexical coverage conditions (90%, 95%, 98%, 100%) while their eye movements were recorded. Knowledge of unknown pseudowords in the texts was assessed via an immediate, meaning recall post-test. Results showed that only one of the three global measures examined showed a processing advantage for the 98% condition, reflected by longer saccades and less effortful reading than the 90% and 95% conditions. Crucially, lexical coverage did not have a significant impact on the amount of attention spent on unknown vocabulary. Processing times were found to significantly predict vocabulary gains.

Proof of Concept for the Organic Electrorefinery Technology with Actual Effluents.

This work describes results of a first proof of the concept of electrorefinery with a real waste obtained from a cashew nut factory, and it shows the effect of the current densities of both the anodic oxidation and electrochemically assisted separation processes on the performance of the system. Results obtained demonstrate that electrorefinery is a promising option to minimize the carbon fingerprint, worth studying for increasing the sustainability of the environmental remediation of wastes, because valuable species can be obtained from the destruction of pollutants and recovered within the same integrated process. They also point out that there is still a long way to reach an optimum solution for this technology, but it is worth the effort to be made. Many different carboxylates were detected, but oxalate was the primary product both in the reaction tank and in the recovery tank. The production is almost linear during the electrolysis, with a reaction rate of 23.3 mg C h-1 in the case of oxalate and a separation ration of around 20% in the electrodialysis stage. There is a negligible crossover of aromatic species into the recovery solution, which becomes an important advantage for further processing of the carboxylate solutions in the search to valorize these species in terms of circular economy principles. Energy efficiencies in the range of 0.04-0.21 mg C-carboxylates (Wh)-1 and Coulombic efficiencies in the range 0.92-2.03 mg C-carboxylates (Ah)-1 were obtained in this work. A life cycle assessment indicated carbon dioxide and water footprints as low as 0.31 g of CO2 mg-1 C and 30 mL of H2O mg-1 C recovered in the products obtained, respectively.

Application of TbF3 Nano-powders by sand milling process in preparing high performance grain boundary diffusion Nd-Fe-B magnets

The Electrophoretic deposition grain boundary diffusion (EPD-GBD) technology for sintered Nd-Fe-B magnets has garnered significant attention. In this study, TbF3 nano-powders were synthesized via sand milling (SM) process, and the optimal processes were subsequently explored. Notably, the SM powders exhibit two morphologies: blocky and flocculent. With prolonged SM time, the proportion of larger blocky powders decreases gradually, while the proportion of smaller flocculent powders increases. The morphology and proportion of the powders significantly impact the EPD rate and the effectiveness of GBD. Higher blocky powders proportion improved diffusion, reducing residual Tb layer and enhancing magnet coercivity. Higher flocculent powders proportion caused cracking, poor diffusion, thicker residual layer, and lower coercivity. However, a high EPD rate was achieved with a high proportion of flocculent powders. Considering both EPD rate and diffusion effect, the SM process at 1500 r/min for 30 minutes was identified as the optimal parameter. The TbF3 nano-powders prepared by these conditions exhibited superior advantage in the EPD process and the coercivity of GBD magnets compared to traditional micron-scale TbF3 powders, demonstrating the benefits of the SM process in the EPD and GBD processes of Nd-Fe-B magnets.

Emojis and affective priming in visual word recognition

ABSTRACT Emojis are frequently used in digital communication to supplement the lack of non-verbal cues, but their integration during reading has not been thoroughly examined. This study explores the interplay between language and emotion by testing the influence of emotional valence and face-status of emojis on visual word recognition. Two online experiments were conducted with 92 native English-speaking university students, examining priming effects between congruent (e.g. delicious) and incongruent (e.g. hate) prime-target pairs, varying the face-status of the emoji prime (face vs. non-face) and the valence (positive vs. negative) of the word target. Irrespective of valence, face emojis demonstrated a processing advantage over non-face emojis, implying automatic attention capture. Additionally, the results revealed an interaction between prime-target congruency and valence, with a facilitatory effect for positive, but not negative, items, suggesting a valence-specific mechanism of affective priming in the lexical decision task. The research suggests that the rapid integration of emoji content occurs during the early stages of visual word recognition, with heightened attentional sensitivity to both face-like and positive stimuli when reading digital communications.

The Neural Correlates of Alcohol Approach Bias - New Insights from a Whole-Brain Network Analysis Perspective.

Alcohol approach bias, a tendency to approach rather than to avoid alcohol and alcohol-related cues regardless of associated negative consequences, is an emerging key characteristic of alcohol use disorder (AUD). Reaction times from the Approach-Avoidance Task (AAT) can be used to quantify alcohol approach bias. However, only a handful of studies have investigated the neural correlates of implicit alcohol approach behavior. Graph Theory Analysis (GTA) metrics, specifically, weighted global efficiency (wGE), community detection, and inter-community information integration were used to analyze functional magnetic resonance imaging (fMRI) data of an in-scanner version of the AAT from 31 heavy drinking Veterans with AUD (HDV) engaged in out-patient treatment and 19 healthy Veterans as controls (HC). We found a functional imprint of alcohol approach bias in HDVs. HDVs showed significantly higher wGE values for approaching than for avoiding alcohol, indicating that their brain was more efficiently organized or functionally set to approach alcohol in the presence to alcohol-related external cues. In contrast, Brains of HCs did not show such a processing advantage for either the approach or avoid condition. Further post-hoc analyses revealed that HDVs and HCs differed in how they implemented top-down control when approaching/avoiding alcohol and in how the fronto-parietal control network interacted with subsystems of the default mode network. These findings contribute to understanding the complex neural underpinnings of alcohol approach bias and lay the foundation for developing more potent and targeted interventions to modify these neural patterns in AUD patients.

Self-validating photoelectrochemical/photoelectrochromic visual sensing platform for ciprofloxacin precise detection in milk

BackgroundIn the process of food production, ciprofloxacin (CIP), a highly prescribed fluoroquinolone antibiotic, is often excessively used to reduce the risk of bacterial infection. However, this overuse can cause severe harm to human health, including allergic responses, gastrointestinal complications, and potential renal dysfunction. The development of a robust and precise detection method for CIP is crucial, given the interconnection between food security and human health. Compared to the single-mode detection methods currently in use, dual-mode detection provides enhanced accuracy in detecting results due to its inherent self-validation and self-correction capabilities. ResultsHerein, a photoelectrochemical and photoelectrochromic self-validated dual-mode sensing platform was developed to detect CIP in milk by laser etching method, signal generation (SG) region, signal output (SO) region and conductive channel was integrated on the same fluoide-doped tin oxide electrode and Ti3C2/ZnO composite was modified in the electron SG region, and Prussian blue (PB) was electrodeposited in the SO region. By irradiating the SG region, photogenerated electrons are generated and injected into the SO region through the conductive pathway, resulting in the reduction of the PB to Prussian white (PW). Because the binding of CIP to its specifically recognized aptamers hinders electron transfer, a “Signal-Off” response mechanism can be used for simultaneous quantitative detection of CIP using photocurrent or color changes, which presents a great advantage in the detection process. SignificanceBy integrating different detection mechanisms within a single linear range, the constructed dual-mode sensor has a wide detection range and low detection limit in milk samples. Additionally, it shows good selectivity in anti-interference experiments, providing a new idea for the development of visual analysis and detection platforms for food safety.

During this period, children undergo significant advancements in various domains, such as physical, mental, and social development. Thus, outdoor activities are a crucial means to support development in these areas. The present literature review will examine the advantages of engaging children in outdoor activities during their kindergarten years. Our objective is to clarify the various benefits of outdoor activities for kindergarten children, including physical, cognitive, social, mental health, and sensory processing advantages.

Application of wavelet and seasonal-based emotional ANN (EANN) models to predict solar irradiance

This study models solar irradiance at six stations in Iran and the USA on an hourly scale. We explored two seasonal emotional artificial neural networks (EANN): sequence-EANN (SEANN) and wavelet EANN (WEANN). Analyzing ten years of climatic and solar data, we evaluated uncertainty using prediction intervals (PIs) computed via the bootstrap method based on artificial neural networks (ANNs). Unlike standalone EANNs, the proposed seasonal models effectively captured seasonal information and leveraged time series processing advantages. Utilizing Wavelet and Fourier transforms, these models captured long-short autoregressive dependencies in solar irradiance, addressing extended seasonal dependencies. Results showed that the seasonal EANN models outperformed the classic EANN model by approximately 15 % and the classic feed-forward neural network (FFNN) by about 25 % in both training and testing. The WEANN model demonstrated the highest performance in PIs, with an average normalized mean PI width (NMPIW) of 0.8 and an average PI coverage probability (PICP) of 0.96.

Installation of Copper(I) and Silver(I) Sites into TREN-Based Porous Organic Cages via Postsynthetic Metalation.

Porous organic cages (POCs) and metal-organic polyhedra (MOPs) function as zero-dimensional porous materials, able to mimic many functions of insoluble framework materials while offering processability advantages. A popular approach to access tailored metal-based motifs in extended network materials is postsynthetic metalation, which allows metal installation to be decoupled from framework assembly. Surprisingly, this approach has only sparingly been reported for molecular porous materials. In this report, we demonstrate postsynthetic metalation of tetrahedral [4 + 4] POCs assembled from tris(2-aminoethyl)amine (TREN) and 1,3,5-tris(4-formylphenyl)benzene. The trigonally symmetric TREN motif is a common chelator in coordination chemistry and, in the POCs explored herein, readily binds copper(I) and silver(I) to form cationic cages bearing discrete mononuclear coordination fragments. Metalation retains cage porosity, allowing us to compare the sorption properties of the parent organic and metalated cages. Interestingly, introduction of copper(I) facilitates activated oxygen chemisorption, demonstrating how targeted metalation can be exploited to tune the sorption characteristics of porous molecular materials.

Chinese EFL learners' processing of English binomials: the role of interlexical and intralexical factors.

Binomials have been relatively understudied compared to other types of multiword expressions (MWEs) in second language research, such as collocations and idioms. This study investigated English as a Foreign Language (EFL) learners' processing of English binomials and how it is influenced by interlexical factors (L1-L2 congruency and L1-lexicalization) and intralexical factors (word and binomial frequency, binomial reversibility, and binomial predictability). Forty Chinese EFL learners participated in a phrase acceptability judgment task of 64 target binomials (16 congruent L1-lexicalized, 16 congruent L1-nonlexicalized, and 32 incongruent) and 64 non-binomial controls. Results revealed that learners experienced difficulty judging the formulaicity of binomials. They processed binomial stimuli significantly faster than non-binomial baselines, demonstrating a binomial phrase effect. They also processed L1-L2 congruent items faster and more accurately than incongruent items, showing a robust congruency effect. The congruent items which are lexicalized in the L1 showed further processing advantage than the non-lexicalized items, indicating a graded congruency effect. Moreover, binomial reversibility and binomial predictability (measured with cloze probability) also showed significant effects. These findings highlight the need to distinguish and investigate different types of congruency, explore appropriate measures for MWE predictability, and to examine binomials focusing on their unique features.

Fast and selective isoprene gas sensor: Influence of polystyrene size and role of the au catalyst on gas sensing properties

Sacrificial methods using polystyrene (PS) templates are extensively applied in various research fields, particularly for fabricating gas sensors. The many processing advantages of these methods, such as a uniform particle size distribution, ease of manipulation, and potential for functionalization enable the fabrication of intricate nanostructures with precise control of the geometry and surface-area-to-volume ratio. Nevertheless, no previous study has investigated the fundamental correlation between the size of the PS particles used as a template and the performance of the resulting functional gas sensor. In this study, we fabricated In2O3 hollow hemispheres (HHs) with PS template sizes ranging from 200 to 3000 nm to explore the essential aspects for gas sensor applications. Notably, compared to In2O3 thin films, In2O3 HHs-based sensors prepared using a 3000 nm PS template exhibited a larger surface area, particularly when formed in a monolayer, and achieved an enhanced gas response to C2H5OH by approximately 132 times. By decorating In2O3 HHs with Au nanoparticles, the detection of C5H8 at 350 ℃ among various volatile organic compounds was significantly enhanced (increase ratio = 31.7), achieving a response of 483 and a theoretical detection limit as low as 743 parts per trillion (ppt). In addition, the highly porous structure with Au decoration achieved an extremely short response time of less than 2 s. These unprecedented results provide critical insights into conventional sensor technologies and pave the way for potential health-monitoring applications and bioelectronics.

Formulation of novel low-sodium salts using potassium salts and dietary polysaccharide

Potassium citrate (KC) and potassium lactate (KL) are considered as salt replacers due to their saltiness, processing advantages, and health benefits. However, the obvious bitter taste associated with these compounds has limited their use in salt substitutes. Despite this challenge, little attention has been paid to improving their sensory properties. This study provided evidence that dietary polysaccharide carrageenan can effectively mask the bitterness of KC and KL by specifically binding K+ and forming double helix chains. A highly accurate prediction model was then established for the saltiness and bitterness of low-sodium salts using mixture design principles. Three low-sodium salt formulas containing different potassium salts (KC, KL, KCl), NaCl, and carrageenan were created based on the prediction model. These formulas exhibited favorable saltiness potencies (>0.85) without any noticeable odor, preserving the sensory characteristics of high-sodium food products like seasoning powder while significantly reducing their sodium content. This research provides a promising approach for the food industry to formulate alternative low-sodium products with substantially reduced sodium content, potentially contributing to decreased salt intake.

Transnational social fields of Italian Bangladeshis in Europe and beyond: Towards a new geography of ways of belonging

AbstractIn view of the growing onward migration and multisited transnationalism among naturalized EU citizens, this article seeks to advance the current understanding of transnational social fields, cataloguing the complex interplays of migrants' ways of being, belonging, and in‐betweenness across different places and spaces. Drawing on multisited qualitative research with Italian Bangladeshis in Italy and the United Kingdom, the paper presents how their ‘ways of being’ are expressed by maintaining transnational attachments to the country of origin and the wider Bangladeshi diaspora. In addition, they maintain transnational ‘ways of belonging’ by incorporating the Bengali language, culture, traditions, and values, and transmitting them to the next generation. Beyond these multiplicities of being and belonging, the findings put forward two important, yet contrasting, observations. On the one hand, there is an ongoing pursuit of onward migration to the UK among a section of the community—often influenced by social networks and transnational connections with the recognised Bangladeshi diaspora in the UK. Apart from being in the ‘community comfort zone’ and language advantage in the integration process, many migrants perceive living in the UK as having a higher ‘prestige’, ‘class’ or ‘status’ vis‐a‐vis Italy in terms of life quality, wealth, cultural, and religious freedom. On the other hand, another cohort is emotionally and culturally embedded in Italian societies and is in a dilemma of whether to migrate onward. In this process, they constantly blend, shift, and negotiate their ways of belonging. The findings unfold how a new geography of belonging takes shape, characterised by fluidities, multifaceted identities, and everyday life practices in a transnational space.

Flight patterns of monocularly occluded homing pigeons further reveal a left eye/right cerebral hemispheric advantage in the visual processing of familiar landscape/landmark features

Studying pigeons during homing has offered an opportunity to investigate visual–functional brain lateralization in the context of free flying and long distance navigation. In the current study we examine at a high scale of spatial resolution the flight paths of pigeons, which vary with respect to monocular and binocular treatment, as they familiarise themselves with landscape and landmark features during repeated flights home from two locations. The analysis of the flight paths of monocularly occluded pigeons revealed that pigeons using the right eye/left hemisphere visual system were more likely to display more tortuous paths over tracts of 500 m along the flight path home compared to both pigeons using the left eye/right hemisphere visual system and control birds. Accompanying this finding was the observation that pigeons using the right eye/left hemisphere system were more likely to perform flight “loops”, suggesting that, without right hemispheric visual processing, pigeons are more motivated to seek out visual input, behaviourally expanding the now monocularly reduced visual field. Taken together, the data are consistent with a more important role of the left eye/right hemisphere system in processing visual features of the landscape, which may contribute to the construction of the familiar landmark-based map used for navigation. More broadly, our data are consistent with the hypothesis that the right cerebral hemisphere of the avian brain plays a more important role in memorising and using the relational properties of visual stimuli to guide performance on spatial tasks.
