Continuous and Unified Person Re-Identification

Person re-identification (ReID) aims to match pedestrian images across disjoint cameras. Mainstream Re-ID tasks focus on training ReID models once using all the data, which become limited in some real-world scenarios where training data tends to arrive in stages. To match scenarios where training data is incrementally available, some works began to explore ReID task that can make efficient use of piecemeal new data. However, due to the limitations of the training and testing setups, these efforts are still preliminary explorations. In this letter, we explore a novel yet harder Continuous and Unified ReID (CUReID), which not only enables to continuously learn discrimination knowledge from data streams with style differences, but also to be uniformly evaluated discriminatory capability on all the data (seen and unseen). Furthermore, we propose a novel Generalized Feature Decoupled Learning (GFDL) framework for CUReID, which characterizes by introducing alternate training with extra images to solve the problem of optimization divergence between regularisation (learning new knowledge) and generalization (anti-forgetting old knowledge) tasks. In our newly proposed benchmark setup, GFDL achieves the state-of-the-art performance.
Value Propositions in Heritage Tourism Site Business Models in the Context of Open Innovation Knowledge Transfer

This article discusses the structures of value propositions in cultural heritage tourism site business models in the context of the concept of open innovation. The objective of the study is to identify value propositions in tourism sites and the tendency of managers to use open innovation. The analysis was based on the example of European cultural heritage tourism sites associated with the European Route of Industrial Heritage. The research process included literature analysis and empirical research in the form of interviews conducted with managers of 73 sites. The research allowed for identifying 16 key values observed in the business models of cultural heritage tourism sites and then classify them into three groups, i.e., values proposed to the customer, values captured by the enterprise and social values. The following values were of the highest importance: promotion of historical industrial heritage, satisfying cognitive needs, acting as a symbol of the area, brand strengthening and organization of tourist traffic, so that the industrial heritage is preserved. It was noticed that some values were significantly correlated with the attitudes of managers towards the exchange of knowledge within open innovation. The majority of managers participating in the research were convinced that the revitalization of cultural heritage sites and the business models of these sites should be in the form of open innovation. The limitation of the research carried out is the inability to deepen the interviews, which was caused by the lack of direct contact with managers due to the COVID-19 pandemic.
On P-Beauty Contest Integer Games

In this paper we provide a full characterization of the pure-strategy Nash Equilibria for the p-Beauty Contest Game when we restrict player’s choices to integer numbers. Opposed to the case of real number choices, equilibrium uniqueness may be lost depending on the value of p and the number of players: in particular, as p approaches 1 any symmetric profile constitutes a Nash Equilibrium. We also show that any experimental p-Beauty Contest Game can be associated to a game with the integer restriction and thus multiplicity of equilibria becomes an issue. Finally, we show that in these games the iterated deletion of weakly dominated strategies may not lead to a single outcome while the iterated best-reply process always does (though the outcome obtained depends on the initial conditions).
Comparison of the Influence of Two Types of Plasma Treatment of Short Carbon Fibers on Mechanical Properties of Epoxy Composites Filled with These Treated Fibers

The interfacial interface between fibers and matrix plays a key role for epoxy matrix composites and short recycled randomly arranged fibers. This study used short recycled carbon fiber (RCF) as a filler. Plasma treatment was used for carbon fiber surface treatment. This treatment was performed using radio (RF) and microwave (MW) frequencies at the same pressure and atmosphere. Appropriate chemical modification of the fiber surfaces helps to improve the wettability of the carbon fibers and, at the same time, allows the necessary covalent bonds to form between fibers and the epoxy matrix. The effect of the plasma treatment was analyzed and confirmed by X-ray photoelectron spectroscopy, Raman microscopy, scanning electron microscopy, transmission electron microscopy and wettability measurements. Composite samples filled with recycled carbon fibers with low concentrations (1 wt%, 2.5 wt% and 5 wt%) and high concentrations (20 wt% and 30 wt%) were made from selected treated fibers. The mechanical properties (impact toughness, 3PB) were analyzed on these samples. It was found that the modulus of elasticity and bending stress increase with the increasing content of recycled carbon fibers. A more significant change in impact strength occurred in samples with low concentration.
Child maltreatment prevention interventions for Latinx immigrant populations: a systematic review

ABSTRACT A growing population of immigrant children and families to the U.S. from Latin American countries requires consideration of their unique historical, sociocultural, and linguistic contexts in child abuse and neglect prevention. In light of the Family First Prevention Services Act’s focus on evidence-based child maltreatment prevention interventions, this systematic review analyzed interventions with relevance for use with immigrant populations coming from Latin American countries. Sixty-two interventions met inclusion criteria. This review revealed few gold standard interventions that address the unique needs of Latinx immigrant populations, highlighting a need for the development and study of interventions for these populations that are federally reimbursable.
Quantum unitary evolution of linearly polarized and Gowdy models coupled to massless scalar fields

The purpose of this paper is to study in detail the problem of defining unitary evolution for linearly polarized and Gowdy models (in vacuum or coupled to massless scalar fields). We show that in the Fock quantizations of these systems no choice of acceptable complex structure leads to a unitary evolution for the original variables. Nonetheless, unitarity can be recovered by suitable redefinitions of the basic fields. These are dictated by the time-dependent conformal factors that appear in the description of the standard deparameterized form of these models as field theories in certain curved backgrounds. We also show the unitary equivalence of the Fock quantizations obtained from the SO(3)-symmetric complex structures for which the dynamics is unitarily implemented.
Kurdish Language in Iraqi Kurdistan under Constant Threat of Marginalization and Declination

The study on which this article is based demonstrates the critical situation of Kurdish language in Iraqi Kurdistan Region and warns the officials and the Kurdish academics of the threat of English which is one of the main factors of Kurdish language decline and marginalization in Iraqi Kurdistan where the process of resisting language shift is not as required. One of the major questions this study tries to answer could revolve around the role of English in putting aside the Kurdish language in Iraqi Kurdistan where private schools use English as the first language for their Kurdish students. Likewise, this paper tries to focus on other factors that result into the marginalization of Kurdish language in Iraqi Kurdistan and it aims at searching for the symptoms of language marginalization and declination? What should be done to resist the decline produced in language is one of the essential objectives beyond writing this research. Meanwhile, it tries to know the role of language policy (if there is any) towards Kurdish language? Since Kurdish language is under constant threat of marginalization and declination, any attempt to protect and revitalize it would contribute to revive the Kurdish language for future generation. Depending on a descriptive method, this study arrives at the fact that what has been done till now in terms of the threat of English and its domination which gradually marginalizes Kurdish language is not as required and it explores the ways to be taken to resist such a language threat.
Modeling Longitudinal Ordinal Response Variables for Educational Data

This article presents applications for the analysis of multilevel ordinal response data through the proportional odds model. Data are drawn from the public-use Early Childhood Longitudinal Study. Results showed that gender, number of family risk characteristics, and age at kindergarten entry were associated with initial reading proficiency (0 to 5 scale). The number of family risks and age were associated with time-slopes. Three issues are highlighted: building multilevel ordinal models, interpretation of multilevel effects; and determination of predicted probabilities based on results of the multilevel proportional odds models.
Intratumoral synthesis of transformable metal-phenolic nanoaggregates with enhanced tumor penetration and retention for photothermal immunotherapy

Rationale: Effective photothermal therapy (PTT) remains a great challenge due to the difficulties of delivering photothermal agents with both deep penetration and prolonged retention at tumor lesion spatiotemporally. Methods: Here, we report an intratumoral self-assembled nanostructured aggregate named FerH, composed of a natural polyphenol and a commercial iron supplement. FerH assemblies possess size-increasing dynamic kinetics as a pseudo-stepwise polymerization from discrete nanocomplexes to microscale aggregates. Results: The nanocomplex can penetrate deeply into solid tumors, followed by prolonged retention (> 6 days) due to the in vivo growth into nanoaggregates in the tumor microenvironment. FerH performs a targeting ablation of tumors with a high photothermal conversion efficiency (60.2%). Importantly, an enhanced immunotherapeutic effect on the distant tumor can be triggered when co-administrated with checkpoint-blockade PD-L1 antibody. Conclusions: Such a therapeutic approach by intratumoral synthesis of metal-phenolic nanoaggregates can be instructive to address the challenges associated with malignant tumors.
A REPRESENTATION SHIFT MODEL OF CLASSIFICATION AND ABSOLUTE IDENTIFICA TION

We studied shifts of representation using production trials to measure the representation following classification and absolute identification. Identification induced a shift of representation away from the preceding exemplar. Shifts in classification depended on the category of the preceding trial. When the exemplars were from different categories, the category representation was pushed away from the preceding category. When the exemplars were from the same category, the representation of the current category was pulled from its centre in the direction of the preceding exemplar. We propose a representation shift model to account for trial-to-trial errors in both tasks. The model treats the subject’ s representation of category and item structure as points in a space. The points shift dynamically from trial to trial as a function of the properties of the preceding exemplar. The RSM captures overall accuracy in both classification and absolute identification, replicates benchmark characteristics of performance in both absolute identification, and classification.
Transport of Galactic Cosmic Rays in the Heliosphere: Stochastic Simulation Approach

In the present paper we consider a possibility of using stochastic simulation (Monte-Carlo) technique approach to the study of Galactic Cosmic Ray propagation in the Heliosphere. We developed a technique for calculation of the Cosmic Ray propagation in a spherically symmetric steady state approximation of the Heliosphere. In the frameworks of this approximation, we study the solar modulation of monoenergetic fluxes of Galactic Cosmic Rays entering the Heliosphere, in the particle’s energy range 0.1 15 GeV. Besides, we present the first results of our simulation of 2D Heliosphere.
Regulation of cGAS Activity and Downstream Signaling

Cyclic GMP-AMP synthase (cGAS) is a predominant and ubiquitously expressed cytosolic onfirmedDNA sensor that activates innate immune responses by producing a second messenger, cyclic GMP-AMP (cGAMP), and the stimulator of interferon genes (STING). cGAS contains a highly disordered N-terminus, which can sense genomic/chromatin DNA, while the C terminal of cGAS binds dsDNA liberated from various sources, including mitochondria, pathogens, and dead cells. Furthermore, cGAS cellular localization dictates its response to foreign versus self-DNA. Recent evidence has also highlighted the importance of dsDNA-induced post-translational modifications of cGAS in modulating inflammatory responses. This review summarizes and analyzes cGAS activity regulation based on structure, sub-cellular localization, post-translational mechanisms, and Ca2+ signaling. We also discussed the role of cGAS activation in different diseases and clinical outcomes.
EXPRESS: Overcoming path-dependent dynamic capabilities

While seminal work on dynamic capabilities highlights path-dependent trajectories as an important and distinguishing property, recent studies tend to marginalize this feature in favor of an ahistorical and unbound conceptualization. Following the recent ‘history turn’ in strategy and organization research, we examine the essential yet inadequately understood role of path dependence in dynamic capability building and adaptation. Precisely, we demonstrate that dynamic capabilities, as pattern-based, learned, and context-specific entities, are prone to become path-dependent under the effect of self-reinforcing mechanisms. We further show that in the face of discontinuous environmental shifts, path-dependent dynamic capabilities can—paradoxically enough—turn dysfunctional as they perpetuate current, potentially outdated ways through which a firm reconfigures its resource base. Based on this analysis, we identify ad hoc managerial action as the basis for path transformation and path dissolution, as well as path switching and new path creation, which represent complementary ways to deal with path-dependent dynamic capabilities. Our theorizing extends a contingency perspective on dynamic capabilities by shedding light on the limits and potential alternatives of pattern-based adaptation.
Genomic Comparative Analysis of Cordyceps pseudotenuipes with Other Species from Cordyceps

The whole genome of Cordyceps pseudotenuipes was sequenced, annotated, and compared with three related species to characterize the genome. The antibiotics and Secondary Metabolites Analysis Shell (antiSMASH) and local BLAST analysis were used to explore the secondary metabolites (SMs) and biosynthesis gene clusters (BGCs) of the genus Cordyceps. The genome-wide basic characteristics of C. pseudotenuipes, C. tenuipes, C. cicadae, and C. militaris revealed unequal genome size, with C. cicadae as the largest (34.11 Mb), followed by C. militaris (32.27 Mb). However, the total gene lengths of C. pseudotenuipes and C. tenuipes were similar (30.1 Mb and 30.06 Mb). The GC contents of C. pseudotenuipes, C. tenuipes, C. cicadae, and C. militaris genomes differed slightly (51.40% to 54.11%). AntiSMASH and local BLAST analysis showed that C. pseudotenuipes, C. tenuipes, C. cicadae, and C. militaris had 31, 28, 31, and 29 putative SM BGCs, respectively. The SM BGCs contained different quantities of polyketide synthetase (PKS), nonribosomal peptide synthetase (NRPS), terpene, hybrid PKS + NRPS, and hybrid NRPS + Other. Moreover, C. pseudotenuipes, C. tenuipes, C. cicadae, and C. militaris had BGCs for the synthesis of dimethylcoprogen. C. pseudotenuipes, C. tenuipes, and C. cicadae had BGCs for the synthesis of leucinostatin A/B, neosartorin, dimethylcoprogen, wortmanamide A/B, and beauvericin. In addition, the SM BGCs unique to C. pseudotenuipes were clavaric acid, communesin, and deoxynivalenol. Synteny analysis indicated that the scaffolds where the SM BGC was located were divided into more than 70 collinear blocks, and there might be rearrangements. Altogether, these findings improved our understanding of the molecular biology of the genus Cordyceps and will facilitate the discovery of new biologically active SMs from the genus Cordyceps using heterologous expression and gene knockdown methods.
Vastus Lateralis and Vastus Intermedius as Predictors of Quadriceps Femoris Muscle Hypertrophy after Strength Training

The aim of the present study was to investigate which of the four musle heads of the quadriceps femoris is the best surrogate of quadriceps hypertrophy, following resistance training, evaluated by ultrasonography. Forty three physical education students (age: 22.1 ± 3.1 years, height: 175.2 ± 9.3 cm, mass: 75.3 ± 8.0 kg, BMI: 22.8 ± 2.8 kg·m−2) participated in the study. Participants followed an 8-week resistance training program in order to enhance quandriceps muscle hypertrophy. Before and after the training period muscle ultrasonography was used to evaluate: total quandriceps (T), vastus lateralis (VL), vastus intermidius (VI), vastus medialis (VM) and rectus femoris (RF) cross sectional area (CSA). Total quadriceps’ as well as VL, VI and VM, CSAs were significantly increased after training (changes ranged between 10.9 ± 9.9% and 18.6 ± 10.8%; p < 0.05). No significant changes were found for RF CSA after training (p > 0.05). Agreement analyses revealed high values for VL and VI (e.g., ICC = 0.879–0.915; p = 0.000), and low values for VM and RF (e.g., ICC = 0.132–0.526; p = 0.000). These results suggest that training-induced changes in muscle hypertrophy in VL and VI measured via muscle ultrasonography may be significantly predict the whole quadriceps hypertrophy in response to lower body resistance training. Consequently, VL and VI may considered as valid surrogates of whole quadriceps muscle hypertrophy.
Risk Factors of Urinary Pathogenic Bacteria Infection after Benign Prostatic Hyperplasia Surgery and Curative Effect Analysis of Shuangdong Capsule Intervention

Benign prostatic hyperplasia (BPH) is a common and frequently occurring disease in clinics, with the main manifestations including frequent micturition, urinary incontinence, dysuria, and endless urination. Transurethral resection of the prostate (TURP) is the main treatment for BPH, but some patients are prone to urinary tract infection after surgery, which affects the prognosis. Therefore, it is of great significance to study the pathogenic characteristics and risk factors of postoperative urinary-derived pathogenic bacteria infection in patients with BPH for the prevention and treatment of postoperative infection. In addition, the treatment of patients with this disease is also the focus of clinical attention. Long-term massive application of antibiotics can induce drug-resistant mutations of bacteria, so it is urgent to find an efficient and safe therapeutic scheme in clinics. However, traditional Chinese medicine (TCM) has a long history of treating urinary tract infections. Therefore, Shuangdong capsule, a traditional Chinese medicine preparation, was selected for the combined treatment in this study. The results showed that age, concomitant diabetes mellitus, and preoperative prophylactic application of antibiotics were the independent risk factors for postoperative urine-derived pathogenic infection in BPH patients. Clinical intervention for BPH patients with concomitant risk factors should be emphasized in clinical practice. The combined use of Shuangdong capsule and conventional western medicine can improve the clinical symptoms and inflammatory reactions of postoperative urine-derived pathogenic infection in BPH patients. Due to its exact curative effect and high safety, it is worthy of promotion. The clinical study registration number is M2022019.
Performance study and structure optimization of new type of radial flow field proton exchange membrane fuel cell

ABSTRACT On the basis of a circular bipolar plate (BP) of the proton exchange membrane fuel cell (PEMFC), a new rim-type radial flow field (FF) structure was designed inspired by the rim style of the vehicle. In this type of FF structure, the key variables are the number of layers of annular flow FFs, the number of branched FFs, and the amplitude of the waveform of branched FFs. To compare the effects of these variables on FF (especially the FF of cathode), the PEMFC single-cell model with different variables was developed by COMSOL Multiphysics software and then simulated. The reasonable value of these variables in enhancing the PEMFC performance was finally determined by comparing the oxygen distribution, water distribution, pressure drop on the cathode side, and the fuel cell output voltage and power of different schemes. This study achieves the highest ultimate current density and maximum power density among all schemes when the number of branches is 8. A four-layer structure is the most appropriate for selecting the number of FF layers. For the selection of the curvature of the branch, 15° is the most appropriate.
A review on cultural competency in medical education

Cultural competency is a wide notion with a variety of academic bases and differing perspectives on how it should be implemented. While it is widely acknowledged that cultural competency should be an element of general practise, there is a paucity of literature in this area. It has been commonly claimed that cultural competency is a fundamental prerequisite for working well with persons from different cultural backgrounds. Medical students must learn how to connect successfully with patients from all walks of life, regardless of culture, gender, or financial background. Hence, National Medical Council (NMC) has included cultural competence as a course subject in the curriculum of medical education. The opportunities and concept of Competency Based Medical Education, the inclusion of cultural competency in medical course by NMC, various models and practice skill of cultural competence in medical education are discussed in this paper. This study will be useful to researchers who are looking at cultural competency as a research variable that influences study result.
