A novel domain independent scene text localizer

Text localization across multiple domains is crucial for applications like autonomous driving and tracking marathon runners. This work introduces DIPCYT, a novel model that utilizes Domain Independent Partial Convolution and a Yolov5-based Transformer for text localization in scene images from various domains, including natural scenes, underwater, and drone images. Each domain presents unique challenges: underwater images suffer from poor quality and degradation, drone images suffer from tiny text and loss of shapes, and scene images suffer from arbitrarily oriented, shaped text. Additionally, license plates in drone images may not provide rich semantic information compared to other text types due to loss of contextual information between characters. To tackle these challenges, DIPCYT employs new partial convolution layers within Yolov5 and integrates Transformer detection heads with a novel Fourier Positional Convolutional Block Attention Module (FPCBAM). This approach leverages common text properties across domains, such as contextual (global) and spatial (local) relationships. Experimental results demonstrate that DIPCYT outperforms existing methods, achieving F-scores of 0.90, 0.90, 0.77, 0.85, 0.85, and 0.88 on Total-Text, ICDAR 2015, ICDAR 2019 MLT, CTW1500, Drone, and Underwater datasets, respectively.

Esterification-Induced Spontaneous Deposition of Nanoparticle Monolayers on Substrates with Percolation Network Morphology.

Nanoparticle monolayers (NPMLs) exhibit unique collective properties that are highly desirable for applications in sensors, catalysts, and optics. However, their practical use is often hindered by structural instability, especially when they are exposed to solvents. In this study, we developed a method for the spontaneous deposition of gold nanoparticle monolayers (AuNPMLs) on silicon substrates via covalent bonding interactions that provides excellent structural stability in solvents with varying polarities. The esterification reaction between carboxyl-functionalized gold nanoparticles and alkyl-chloride-functionalized silicon substrates spontaneously forms AuNPMLs on the substrate in which single-crystalline domains are interconnected, forming a percolation network morphology. The ex situ scanning electron microscopy measurements show that the surface coverage of AuNPMLs rapidly increases up to ca. 60% during the initial 10 min, followed by gradual growth and saturation at ca. 70% at 360 min of deposition time. On the other hand, the single-crystalline domain size reaches its maximum at 45 min and then gradually decreases, which may be attributed to the desorption of AuNPs by the hydrolysis of ester bonds. The reflectance spectra of AuNPMLs showed the red shift as the deposition time increases up to 45 min with a subsequent blue shift thereafter, which is consistent with the change of the single-crystalline domain size with the deposition time. The covalent bonding interaction-mediated nanoparticle deposition method can be used to form stable AuNPMLs with controlled surface coverage and domain size, allowing for fine control of the optical properties and possibly other properties. The excellent structural stability of AuNPMLs and their controlled properties may provide new opportunities for practical applications of NPMLs.

Полномочия главы крестьянского (фермерского) хозяйства по распоряжению общим имуществом: сущность и механизмы ограничения

The article contains a detailed analysis of the subjective aspect of the disposal of common property belonging to members of a non-subject peasant (farm) enterprise, first of all, in terms of the (in)expediency of the model «the proper subject of disposal is exclusively the head of the enterprise», as well as the (un)justified characterization of the actions of the head as representative; the author proves the relevance of not only contractual, but also centralized regulation of relations related to limiting the powers of the named person (through the introduction of a mechanism for mandatory obtaining the consent of members of the farm to carry out certain administrative acts, etc.).

Private ownership in monopolistic competition models

Motivated by empirical evidence, I study the properties of a monopolistic competition model with private ownership. Toward that goal, I consider a monopolistic competition model with additive preferences, homogeneous workers and homogeneous firms. I then introduce in such a standard framework a single additional ingredient: private ownership. Private ownership means that each firm is owned and managed by a single household called the entrepreneur, and this entrepreneur receives profits as sole revenues. In turn, private ownership changes the nature of entry. Free entry in the industry is no longer satisfied. Rather, the number of firms is now determined through occupational choice. Armed with this new framework, I provide a full characterization of a market equilibrium, and compare it to the standard model with collective ownership and free entry. Notably, I find new results concerning optimality, the transmission of aggregate shocks and the ability of the new model to replicate well-established empirical facts.

Unveiling crystal orientation-dependent interface property in composite cathodes for solid-state batteries by in situ microscopic probe

A critical bottleneck toward all-solid-state batteries lies in how the solid(electrode)-solid(electrolyte) interface is fabricated and maintained over repeated cycles. Conventional composite cathodes, with crystallographically distinct electrode/electrolyte interfaces of random particles, create complexities with varying (electro)chemical compatibilities. To address this, we employ an epitaxial model system where the crystal orientations of cathode and solid electrolyte are precisely controlled, and probe the interfaces in real-time during co-sintering by in situ electron microscopy. The interfacial reaction is highly dependent on crystal orientation/alignment, especially the availability of open ion channels. Interfaces bearing open ion paths of NCM are more susceptible to interdiffusion, but stabilize with the early formed passivation layer. Conversely, interfaces with closed ion pathway exhibit stability at intermediate temperatures, but deteriorate rapidly at high temperature due to oxygen evolution, increasing interfacial resistance. The elucidation of these distinct interfacial behaviors emphasizes the need for decoupling collective interfacial properties to enable rational design in solid-state batteries.

Generating synthetic identifiers to support development and evaluation of data linkage methods

We aimed to develop a framework for generating synthetic identifier datasets to support development and evaluation of data linkage methods. We evaluated whether replicating associations between attributes and identifiers improved the utility of the synthetic data for assessing linkage error. We determined the steps required to generate synthetic identifiers that replicate the properties of real-world data collection. We generated synthetic versions of a large United Kingdom cohort study (the Avon Longitudinal Study of Parents and Children), according to the quality and completeness of identifiers recorded over several waves of the cohort. We evaluated the utility of the synthetic identifier data in terms of assessing linkage quality (false matches and missed matches). Comparing data from two collection points in ALSPAC, we found within-person disagreement in identifiers (differences in recording due to both natural change and non-valid entries) in 18% of surnames and 12% of forenames. Rates of disagreement varied by maternal age and ethnic group. Synthetic data provided accurate estimates of linkage quality metrics compared with the original data (within 0.13-0.55% for missed matches and 0.00-0.04% for false matches). Incorporating associations between identifier errors and maternal age/ethnicity improved synthetic data utility. Replicating dependencies between attribute values (e.g. ethnicity), values of identifiers (e.g. name), identifier disagreements (e.g. missing values, errors or changes over time), and their patterns and distribution structure enables generation of realistic synthetic data that can be used for robust evaluation of linkage methods. Our framework provides a novel and generalisable mechanism for developing and benchmarking record linkage algorithms.

Development of a database structure for the first Geomorphological map of Greece at 1:1,000,000 scale

Geomorphological maps offer researchers multiple advantages when studying an area, as they can provide insights into the formation processes of the observed landforms, as well as their possible evolution in the future. The geodatabase seems to be of primary importance, as it determines the way in which the data will be organized and presented on a map, and thus the map’s functionality. There are not specific guidelines for a database for geomorphological maps, as this would be dependent, inter alia, on the scale of the maps. However, up to this day, there is not a single data base template to be used for geomorphological mapping. In each case, the cartographer/geomorphologist determines the number of fields their layers will have and their type, as well as what information they will contain, depend-ing on the scale they are working on, the variety of landforms of their area, the time and resources available (correspondingly, the accuracy their map will have) and the purpose of its creation. Also, while several countries - not only large ones, but smaller ones as well - do have a geomorphological map at national scale, many countries, Greece among them, do not. On the contrary, only parts of them have been mapped by various researchers, who did not share any common database, which renders the combination of the individual maps difficult. But even in countries with existent national geomorphological maps, a specific and common geodatabase structure was not followed. In this way, there is no uniformity in the data and comparisons between maps, as well as combinations of data are very difficult and require a lot of work. Therefore, as we have initiated a project to create the geomorphological map of the Greek territory at 1:1,000,000 scale, we found that, prior to the beginning of the mapping, it was imperative to create a geodatabase template which we intend to follow, and which can be used as a template for geomorphological mapping at national scale by other countries (researchers and/or authorities). Thus, in this paper, we propose a database template to be used in geomorphological mapping at global scale globally, so that the data and structure of maps share common properties, thus allowing for comparisons and combina-tions of data where necessary.

Towards a livelihood-interdependence approach to framing adaptation in research and practice: evidence from farmers’ and herders’ relations in Northern Ghana

ABSTRACT Changing farmer–herder relations (FHR) are central to the social dynamics of climate change adaptation in African drylands, involving conflict and cooperation. While substantial literature has built a case for increased conflict of various kinds in West African drylands due to climate change stressors, this literature does not yet fully reflect the growing importance of more cooperative and interdependent elements of FHR. This study addresses this research gap through a case study of Gushiegu and Karaga Districts in Northern Ghana. Our analysis found growing cooperation between farmers and herders driven by livelihood diversification, sociocultural conditions such as increasing intermarriage, religious affiliation and the emergence of hybrid conflict resolution mechanisms that reflect a process of institutional bricolage. This deepening interdependence manifests in multiple ways, including knowledge exchange, management of common property resources and the strengthening of “bridging” forms of social capital. Our findings suggest a need to reframe adaptation in research, policy and practice to emphasize these beneficial forms of interdependence in FHR.

Triangulating evidence in health sciences with Annotated Semantic Queries.

Integrating information from data sources representing different study designs has the potential to strengthen evidence in population health research. However, this concept of evidence "triangulation" presents a number of challenges for systematically identifying and integrating relevant information. These include the harmonization of heterogenous evidence with common semantic concepts and properties, as well as the priortization of the retrieved evidence for triangulation with the question of interest. We present Annotated Semantic Queries (ASQ), a natural language query interface to the integrated biomedical entities and epidemiological evidence in EpiGraphDB, which enables users to extract "claims" from a piece of unstructured text, and then investigate the evidence that could either support, contradict the claims, or offer additional information to the query. This approach has the potential to support the rapid review of preprints, grant applications, conference abstracts, and articles submitted for peer review. ASQ implements strategies to harmonize biomedical entities in different taxonomies and evidence from different sources, to facilitate evidence triangulation and interpretation. ASQ is openly available at https://asq.epigraphdb.org and its source code is available at https://github.com/mrcieu/epigraphdb-asq under GPL-3.0 license.

GRB 190114C: Fireball Energy Budget and Radiative Efficiency Revisited

The jet composition of gamma-ray bursts (GRBs), as well as how efficiently the jet converts its energy to radiation, are long-standing problems in GRB physics. Here, we reported a comprehensive temporal and spectral analysis of the TeV-emitting bright GRB 190114C. Its high fluence (∼4.4 × 10−4 erg cm−2) allows us to conduct the time-resolved spectral analysis in great detail and study their variations down to a very short timescale (∼0.1 s) while preserving a high significance. Its prompt emission consists of three well-separated pulses. The first two main pulses (P 1 and P 2) exhibit independently strong thermal components, starting from the third pulse (P 3) and extending to the entire afterglow, the spectra are all nonthermal, and the synchrotron plus Compton upscattering model well interprets the observation. By combining the thermal (P 1 and P 2) and the nonthermal (P 3) observations based on two different scenarios (global and pulse properties) and following the method described in Zhang et al., we measure the fireball parameters and GRB radiative efficiency with little uncertainties for this GRB. A relevantly high GRB radiative efficiency is obtained based on both the global and pulse properties, suggesting that if GRBs are powered by fireballs, the efficiency can sometimes be high. More interestingly, though the observed parameters are individually different (e.g., the amount of mass loading M), the radiative efficiency obtained from P 1 (η γ = 36.0% ± 6.5%) and P 2 (η γ = 41.1% ± 1.9%) is roughly the same, which implies that the central engine of the same GRB has some common properties.

Emergence of unitary symmetry of microcanonically truncated operators in chaotic quantum systems.

We study statistical properties of matrix elements of observables written in the energy eigenbasis and truncated to small microcanonical windows. We present numerical evidence indicating that for all few-body operators in chaotic many-body systems, truncated below acertain energy scale, collective statistical properties of matrix elements exhibit emergent unitary symmetry. Namely, we show that below acertain scale the spectra of the truncated operators exhibit universal behavior, matching our analytic predictions, which are numerically testable for system sizes beyond exact diagonalization. We discuss operator and system-size dependence of the energy scale of emergent unitary symmetry and put our findings inthe context of previous works exploring theemergence of random-matrix behavior at small energy scales.

Localized and Long-Lasting Adaptation in Dragonfly Target-Detecting Neurons.

Some visual neurons in the dragonfly (Hemicordulia tau) optic lobe respond to small, moving targets, likely underlying their fast pursuit of prey and conspecifics. In response to repetitive targets presented at short intervals, the spiking activity of these "small target motion detector" (STMD) neurons diminishes over time. Previous experiments limited this adaptation by including intertrial rest periods of varying durations. However, the characteristics of this effect have never been quantified. Here, using extracellular recording techniques lasting for several hours, we quantified both the spatial and temporal properties of STMD adaptation. We found that the time course of adaptation was variable across STMD units. In any one STMD, a repeated series led to more rapid adaptation, a minor accumulative effect more akin to habituation. Following an adapting stimulus, responses recovered quickly, though the rate of recovery decreased nonlinearly over time. We found that the region of adaptation is highly localized, with targets displaced by ∼2.5° eliciting a naive response. Higher frequencies of target stimulation converged to lower levels of sustained response activity. We determined that adaptation itself is a target-tuned property, not elicited by moving bars or luminance flicker. As STMD adaptation is a localized phenomenon, dependent on recent history, it is likely to play an important role in closed-loop behavior where a target is foveated in a localized region for extended periods of the pursuit duration.

서울지역 도시계획에 따른 마을신앙 공동재산의 변화

This paper is a study on the change of village faith common property by urban planning. Urban planning includes physical, economic, and social planning. Changes in village beliefs focused on the influx of foreigners and changes in the local economy, focusing on changes caused by 'urbanization'. Joint property is joint ownership, and village faith joint property should be understood as the concept of 'overall ownership' among the classifications of joint ownership. Joint ownership is a form of joint ownership of one object by multiple people with two or more people, and overall ownership is jointly owned, used, and disposed of. Community property of village beliefs is property owned by the village community in order to transmit village beliefs, and is classified as material, social, and intellectual property. The development of Seoul by urban space planning can be divided into three stages. The first stage was in the 1960s and 1970s when basic infrastructure was built. The second stage was in the 1980s and 1990s, when urban improvement and beautification policies were implemented. The third stage is the 2000-2020s, when underdeveloped areas were maintained and regenerated. The change in common property due to urban planning was examined by dividing physical, social, and intellectual common property. The change in material common property is the movement of the village faith space. The change in social common property is the reconstruction of the transmission community. Intellectual common property is undergoing the weakening and privatization of transmission knowledge.

Examining the effectiveness of interventions to reduce discriminatory behavior at work: An attitude dimension consistency perspective.

Academic interest in reducing discrimination has produced substantial research testing interventions to mitigate biased outcomes. However, disparate findings and a scarcity of studies examining work-related behavioral measures make it challenging to determine which interventions are better suited to reduce workplace discrimination. Derived from the tripartite theory of attitudes and the principle of compatibility, I develop a conceptual model mapping the attitude focus of interventions and code studies in this literature from the past two decades for these common properties. Based on a meta-analysis of 70 articles totaling 208 effect sizes, I test this conceptual model, finding that it helps explain why some interventions to reduce discrimination yield superior outcomes relative to others. In particular, results indicate that passive interventions, such as short-term education or reminders of bias processes, are largely ineffective in shifting behavior. Conversely, the class of interventions that targets behavior directly by attempting to inhibit the manifestation of bias (e.g., making individuals accountable for their decisions or changing social norms) emerged as the most helpful category of interventions in this area. Overall, results support a key prediction of the attitude dimension consistency perspective, demonstrating that aligning the attitude dimension primarily targeted by an intervention and the outcome measured could lead to improved results in this area.

Гражданско-правовое регулирование возникновения долевой собственности в объектах недвижимости

The article examines the features and mechanisms of the emergence of shared ownership in real estate objects based on an analysis of scientific literature and law enforcement practice. In the course of the study, the author revealed that for the emergence of legal relations of common shared ownership, it is necessary to comply with formal conditions and the direct expression of the will of the sole owner of the property, or the consent of all co-owners of such common property. In Russian law, the mechanism of commingling real estate is not possible, as it results in the legal demise of the property. Meanwhile, in doctrine and law enforcement practice, there are concepts of inseparable improvements in property, which also do not entail the emergence of common shared ownership. This pertains to changes made by a lessee to the landlord's real estate. Conclusion dwells upon the fact that the grounds for the emergence of shared ownership are clearly defined by current Russian legislation and do not imply any expansion.

Current and Future Pharmacopoeial Requirements for the Quality of Extemporaneous Medicinal Products: A Review of Regulatory Standards

INTRODUCTION. The organisation of extemporaneous compounding in pharmacies is currently considered to be a priority for the national healthcare system. Extemporaneous medicinal products used by patients should meet high quality, safety, and efficacy standards. Provision of consistent and science-based requirements for the quality of medicines, particularly those compounded in pharmacies, is a key area of concern for standardisation.AIM. This study aimed to analyse international experience and determine areas for the improvement of standardisation approaches of the State Pharmacopoeia of the Russian Federation to the quality of medicinal products compounded in pharmacies.DISCUSSION. The study investigated the common and distinctive properties of extemporaneous preparations compounded in pharmacies (and not subject to registration) and medicinal products manufactured by pharmaceutical companies. The authors analysed the requirements and recommendations for compounding and quality assurance of extemporaneous medicinal products provided by the regulatory and pharmacopoeial authorities of the Russian Federation, the Republic of Belarus, the European Union, the United Kingdom, the USA, and Canada. The United States Pharmacopeia includes circa 150 individual monographs for non-sterile compounded drug products with particular compositions and over 20 individual monographs for sterile compounded drug products. The European Pharmacopoeia requires that extemporaneous preparation should be organised within the quality assurance framework of a pharmacy after a proper risk assessment. In the Republic of Belarus, extemporaneous medicinal products are compounded in line with the requirements of the Good Compounding Practices and the State Pharmacopoeia of the Republic of Belarus, which provide rapid testing procedures for extemporaneous medicinal products.CONCLUSIONS. The study identified the following areas for the development of requirements for the quality of medicinal products compounded in pharmacies: the determination of rapid testing approaches; the development of pharmacopoeial monographs for active pharmaceutical substances used in extemporaneous compounding, with the Identification section supplemented with an additional subsection on pharmacy-specific analytical procedures; and the development of pharmacopoeial monographs for frequently used compounding formulae.

New Insights into the Exosome-Induced Migration of Uveal Melanoma Cells and the Pre-Metastatic Niche Formation in the Liver.

UM is an aggressive intraocular tumor characterized by high plasticity and a propensity to metastasize in the liver. However, the underlying mechanisms governing liver tropism remain poorly understood. Given the emerging significance of exosomes, we sought to investigate the contribution of UM-derived exosomes to specific steps of the metastatic process. Firstly, we isolated exosomes from UM cells sharing a common genetic background and different metastatic properties. A comparison of protein cargo reveals an overrepresentation of proteins related to cytoskeleton remodeling and actin filament-based movement in exosomes derived from the parental cells that may favor the detachment of cells from the primary site. Secondly, we assessed the role of macrophages in reprogramming the HHSCs by exosomes. The activation of HHSCs triggered a pro-inflammatory and pro-fibrotic environment through cytokine production, upregulation of extracellular matrix molecules, and the activation of signaling pathways. Finally, we found that activated HHSCs promote increased adhesion and migration of UM cells. Our findings shed light on the pivotal role of exosomes in pre-metastatic niche construction in the liver.

Common Ownership, Competition, and Corporate Governance

This paper presents a theoretical framework for determining the ownership stakes held by financial investors in companies competing in the same product market, commonly referred to as the level of common ownership. In our model, these investors are primarily motivated by the anticipation of capital gains resulting from the impact of common ownership on product market competition, which enhances profitability for the firms involved. However, common ownership also undermines effective corporate governance by diminishing blockholders’ incentives to engage in value-enhancing behaviors, such as managerial monitoring. These adverse effects on corporate governance act as limiting factors, ultimately determining the equilibrium level of common ownership. This paper was accepted by Joshua Gans, business strategy.

Applications and challenges of digital soil mapping in Africa

The mapping of soils in Africa is at least a century old. We currently have access to various maps depicting mapping units locally and for the continent. In the past two decades, there has been a growing interest in alternatives for generating soil maps through digital soil mapping (DSM) techniques. There are, however, numerous challenges pertaining to the implementation of DSM in Africa, such as the unavailability of appropriate covariates, age and positional error in the measurements, low sampling density, and spatial clustering of the soil data used to fit and validate the models. This review aims to investigate the current state of DSM in Africa, identify challenges specific to implementing DSM in Africa and the ways it has been solved in the literature. We found that nearly half of African countries had an existing digital soil map covering either a local or national area, and that most studies were performed at a local extent. Soil carbon was the most common property under study, whereas soil hydraulic variables were seldom reported. Nearly all studies performed mapping for the topsoil up to 30 cm and calculated validation statistics using existing datasets but without collecting a post-mapping probability sample. Few studies (i.e., 11%) reported an estimate of map uncertainty. Half of the studies had in mind a downstream application (e.g., soil fertility assessment) in the map generation. We further correlated the area of study and sampling density and found a strong negative relationship. About 30% of the studies relied on legacy soil datasets and had a lack of sufficient spatial coverage of their area of study. From this review, we highlight some research opportunities and suggest improvements in the current methodologies. Future research should focus on capacity building in DSM, new data collection, and legacy data rescue. New initiatives, that should be initiated and led from within the continent, could support the long-term monitoring of soils and updating of soil information systems while ensuring their contextualised usability. This pairs with better delivery of existing DSM studies to stakeholders and the generation of a value-added proposition to governmental institutions.
