Enhancing Zero-Shot Action Recognition in Videos by Combining GANs with Text and Images
Authors: Huang Kaiqiang , Miralles-Pechuán Luis , Mckeever Susan
Published: May 2023

Zero-shot action recognition (ZSAR) tackles the problem of recognising actions that have not been seen by the model during the training phase. Various techniques have been used to achieve ZSAR in the field of human action recognition (HAR) in videos. Techniques based on generative adversarial networks (GANs) are the most promising in terms of performance. GANs are trained to generate representations of unseen videos conditioned on information related to the unseen classes, such as class label embeddings. In this paper, we present an approach based on combining information from two different GANs, both of which generate a visual representation of unseen classes. Our dual-GAN approach leverages two separate knowledge sources related to the unseen classes: class-label texts and images related to the class label obtained from Google Images. The generated visual embeddings of the unseen classes by the two GANs are merged and used to train a classifier in a supervised-learning fashion for ZSAR classification. Our methodology is based on the idea that using more and richer knowledge sources to generate unseen classes representations will lead to higher downstream accuracy when classifying unseen classes. The experimental results show that our dual-GAN approach outperforms state-of-the-art methods on the two benchmark HAR datasets: HMDB51 and UCF101. Additionally, we present a comprehensive discussion and analysis of the experimental results for both datasets to understand the nuances of each approach at a class level. Finally, we examine the impact of the number of visual embeddings generated by the two GANs on the accuracy of the models.

Is political skill always beneficial? The relationship between political skill and unethical pro-supervisor behavior
Authors: Cui Zilong , Zhang Kaixin
Published: May 2023

By drawing on social exchange theory, we developed a theoretical model to explore the effect of political skill on unethical pro-supervisor behavior (UPSB) via leader–member exchange (LMX) and the way in which immediate supervisor empowering leadership moderates this mediated relationship. A three-wave study (n = 442) provided evidence suggesting that political skill is positively related to UPSB and that LMX partially mediates this relationship. Immediate supervisor empowering leadership moderates the effect of political skill on LMX, and political skill is positively and indirectly related to UPSB via LMX when the level of immediate supervisor empowering leadership is high. Although political skill is beneficial to both employees and organizations in many respects, our study provides empirical evidence that can improve our understanding of how political skills trigger UPSB. The practical and theoretical implications of our findings are discussed.
The name ’ndrangheta: history versus etymology
Authors: Dickie John
Published: May 2023

The article uses archival sources to critique the currently dominant etymological approach to the history of the word ’ndrangheta as used to refer to the Calabrian mafia. Scholars such as Paolo Martino and John Trumper have latched onto the word's ancient Greek origins to argue that the mafia organisation that we today call ’Ndrangheta has origins dating back many centuries. Moreover, according to Martino in particular, the flattering connotations of the word ’ndrangheta (courage, martial prowess, manliness) indicate that the ’Ndrangheta as a social phenomenon was rooted in the same positive values, and that it only later degenerated into criminality. This article proposes that the work of Martino and Trumper represents a largely evidence-free extension of etymology into the field of history. Analysing the latest archival evidence about the word from criminal trials conducted in the 1920s and early 1930s, and setting it in the context of current historiography and criminology on the ’Ndrangheta, the article argues that two conclusions about the history of the word are likely: that the use of ’ndrangheta as a name for the Calabrian mafia began at around the time it first appeared in the documentary sources; that the first to adopt it were mafiosi themselves.
Beyond the National Museum Paradigm: Troubled Past Vernacular Representations in Central and Southeastern Europe
Authors: Asavei Maria Alina , Králová Kateřina
Published: May 2023

As nationalist and populist rhetorics have gained momentum in Central and Southeastern Europe, there is an urgency to disentangle the historical narratives and political agendas displayed by national museum paradigms. And yet, equally significant is the urgency to illuminate the strategies and mnemonic devices through which the past is rendered worthy of commemoration, both in those memory cultures that come to life in opposition, or those which are complementary to the national museum’s paradigms. In line with these considerations, this special issue addresses the vernacular dimension of public memory, with a special focus on those memory cultures instantiated by mnemonic actors who do not necessarily possess the public epistemic authority to materialize their narratives about violent pasts as official memories.
Alpha particle confinement metrics based on orbit classification in stellarators
Authors: Albert Christopher G. , Buchholz Rico , Kasilov Sergei V. , Kernbichler Winfried , Rath Katharina
Published: May 2023

We present orbit classification schemes for use as fast metrics for fusion alpha particle losses implemented in the symplectic guiding-centre code SIMPLE. Two variants respectively based on conservation of the parallel adiabatic invariant, and topology of footprints in Poincaré sections are introduced. Like an existing approach based on the Minkowski fractal dimension, those methods estimate whether a guiding-centre orbit is regular and therefore expected to be confined for infinite time in the collisionless case, or chaotic, which might lead to its loss. Compared with the existing approach, the required orbit tracing time for the novel classifiers is shorter by at least an order of magnitude. This enables massive sampling of orbits across the whole phase space to identify regular and chaotic regions for the purpose stellarator optimization. Based on conservation of the perpendicular invariant, we demonstrate how extended regular regions may act as radial barriers for orbits from the chaotic regions on the radially inboard side. We propose to use a quantified version of this property as a new metric for collisionless fusion alpha losses. As pitch-angle scattering becomes only relevant after alphas have already deposited a significant fraction of their energy, such a metric remains useful also for the case with collisions. This is illustrated by comparison with collisional loss computations. Results are presented for applications to two quasi-isodynamic configurations, a quasi-helical configuration and two quasi-axisymmetric configurations. In addition, the Hamiltonian action-angle formalism is used in quasi-axisymmetric configurations to investigate the overlap of drift-orbit resonances leading to chaos. The respective analysis is performed with the NEO-RT code originally developed for investigation of neoclassical toroidal viscous torque in tokamak plasmas.

Published: May 2023

Background

Depression and anxiety are common and highly comorbid, and their comorbidity is associated with poorer outcomes posing clinical and public health concerns. We evaluated the polygenic contribution to comorbid depression and anxiety, and to each in isolation.

Methods

Diagnostic codes were extracted from electronic health records for four biobanks [N = 177 865 including 138 632 European (77.9%), 25 612 African (14.4%), and 13 621 Hispanic (7.7%) ancestry participants]. The outcome was a four-level variable representing the depression/anxiety diagnosis group: neither, depression-only, anxiety-only, and comorbid. Multinomial regression was used to test for association of depression and anxiety polygenic risk scores (PRSs) with the outcome while adjusting for principal components of ancestry.

Results

In total, 132 960 patients had neither diagnosis (74.8%), 16 092 depression-only (9.0%), 13 098 anxiety-only (7.4%), and 16 584 comorbid (9.3%). In the European meta-analysis across biobanks, both PRSs were higher in each diagnosis group compared to controls. Notably, depression-PRS (OR 1.20 per s.d. increase in PRS; 95% CI 1.18–1.23) and anxiety-PRS (OR 1.07; 95% CI 1.05–1.09) had the largest effect when the comorbid group was compared with controls. Furthermore, the depression-PRS was significantly higher in the comorbid group than the depression-only group (OR 1.09; 95% CI 1.06–1.12) and the anxiety-only group (OR 1.15; 95% CI 1.11–1.19) and was significantly higher in the depression-only group than the anxiety-only group (OR 1.06; 95% CI 1.02–1.09), showing a genetic risk gradient across the conditions and the comorbidity.

Conclusions

This study suggests that depression and anxiety have partially independent genetic liabilities and the genetic vulnerabilities to depression and anxiety make distinct contributions to comorbid depression and anxiety.
‘Everything Now is Lost’: Stanislavsky’s Last Class at the Opera-Dramatic Studio
Authors: Moschkovich Diego
Published: May 2023

On 22 May 1938, Stanislavsky gathered his group of eleven assistant-pedagogues at the Opera-Dramatic Studio for a last collective class. The Studio was already free for the summer vacation after the tumultuous first show of Chekhov’s Three Sisters, opened only to a small number of guests a week before. Mikhail Kedrov had rehearsed the performance with the students for the preceding three years, and it was doomed to become the first public presentation of the so-called ‘method of physical actions’. Nevertheless, the presentation brought nothing more than doubts about the work done, and Stanislavsky felt compelled to call upon the pedagogues to understand what had happened. After briefly presenting his opinion of the work that had been shown, he started to elaborate on the technical and artistic achievements of the Studio. Stanislavsky began his talk in its stenographic transcript (File No. 21179 in the Stanislavsky Fund of the Moscow Art Theatre Museum Archives) with: ‘Everything now is lost. The technique and all the rest. I don’t see any foundation … any more. You should now start by the critique of the method I have been experimenting on.’ This article analyzes Stanislavsky’s documented talk, showing that he was not convinced that he had a new methodology, let alone one that synthesized his life-long theatre experiments. It seeks to present evidence that both the Physical Action and Active Analysis methodologies derived from Stanislavsky’s thought post mortem were developed only as two possible paths from his experiments, but were not the telos of his thought.

Published: May 2023

We study site and bond percolation in simple directed random graphs with a given degree distribution. We derive the percolation threshold for the giant strongly connected component and the fraction of vertices in this component as a function of the percolation probability. The results are obtained for degree sequences in which the maximum degree may depend on the total number of nodes n, being asymptotically bounded by $n^{\frac{1}{9}}$.
Music Deferred: A Reappraisal of the Legacy of Pierre Schaeffer's Treatise on Musical Objects (1966)
Authors: BAY SUSAN C.
Published: May 2023

This article reinterprets the tension between sound and music in Pierre Schaeffer's 1966 Treatise on Musical Objects. Schaeffer famously insisted that the Treatise did not address music or composition; scholars have therefore engaged with it primarily as a theoretical text on sound and listening. In this article, however, I argue that the denial and deferral of music throughout the Treatise should be considered a discrete and key part of its theoretical contributions. By the early 1960s, Schaeffer's aesthetic frustration with the practice of musique concrète had blossomed into something of an ethical imperative and paradox. He saw it necessary to suspend all musical activity in the present, so as to salvage music's future. This dynamic is key to understanding Schaeffer's controversial and influential calls for the deferral of cultural responses to sound in the Treatise, as illustrated by the practices of ‘deconditioning’ and ‘reconditioning’.
Verifying Ray Tracing Amplitude Methods for Global Magnetospheric Modeling

Published: May 2023

Ray tracing is a commonly used method for modeling the propagation of electromagnetic waves in Earth's magnetosphere. To apply ray tracing results to global models of wave‐particle interaction such as energetic electron scattering, it is useful to map the discrete rays to a volume filling mesh. However, some methods have inherent losses of energy from the wave source, or do not account for the full range of wave properties within a sample volume. We have developed and tested a 3D magnetospheric ray tracing code “MESHRAY” which resolves these issues. MESHRAY uses the conservation of Poynting flux through ray triplets with finite volume to determine the local field amplitudes. Electromagnetic wave energy density from all ray data points is mapped to a mesh and verified against the wave source power for energy conservation varying time step length, number of rays, and total time steps. We find that the method is self‐consistent and numerically robust. We further investigate whether the neglect of phase information and superposition has a significant impact on the accuracy of mapping wave intensity to a mesh. We find excellent agreement between the analytic solution for waves emitted by a line source in a plane‐stratified medium and an equivalent ray tracing solution. When phase information is excluded, ray tracing reproduces an average amplitude spread over regions of coherent constructive and destructive interference. This may be an important consideration for interpolating ray tracing results of longer wavelength waves such as magnetosonic, electromagnetic ion cyclotron, or ULF waves.
Gastrointestinal disorders in Parkinson’s disease and other Lewy body diseases
Authors: Hirayama Masaaki , Nishiwaki Hiroshi , Hamaguchi Tomonari , Ohno Kinji
Published: May 2023

Parkinson’s disease (PD) is pathologically characterized by the abnormal accumulation of α-synuclein fibrils (Lewy bodies) in the substantia nigra and other brain regions, although the role of Lewy bodies remains elusive. Constipation usually precedes the motor symptoms in PD, which is in accordance with the notion that α-synuclein fibrils start from the intestinal neural plexus and ascend to the brain in at least half of PD patients. The gut microbiota is likely to be involved in intestinal and brain pathologies. Analyses of the gut microbiota in PD, rapid-eye-movement sleep behavior disorder, and dementia with Lewy bodies suggest three pathological pathways. First, Akkermansia, which is increased in PD, degrades the intestinal mucus layer and increases intestinal permeability, which triggers inflammation and oxidative stress in the intestinal neural plexus. Second, decreased short-chain fatty acids (SCFAs)-producing bacteria in PD reduce the number of regulatory T cells. Third, SCFAs also aggravate microglial activation with an unelucidated pathway. In addition, in dementia with Lewy bodies (DLB), which is another form of α-synucleinopathies, increased genera, Ruminococcus torques and Collinsella, may mitigate neuroinflammation in the substantia nigra by increasing secondary bile acids. Interventions for the gut microbiota and their metabolites may potentially delay or mitigate the development and progression of PD and other Lewy body diseases.

Published: May 2023

Entanglement distribution is at the heart of most quantum communication protocols. Inevitable loss of photons along quantum channels is a major obstacle for distributing entangled photons over long distances, as the no-cloning theorem forbids the information to simply be amplified along the way as is done in classical communication. It is therefore desirable for every successfully transmitted photon pair to carry as much entanglement as possible. Spontaneous parametric down-conversion (SPDC) creates photons entangled in multiple high-dimensional degrees of freedom simultaneously, often referred to as hyper-entanglement. In this work, we use a multicore fiber (MCF) to show that energy-time and polarization degrees of freedom can simultaneously be transmitted in multiple fiber cores, even maintaining path entanglement across the cores. We verify a fidelity to the ideal Bell state of at least 95% in all degrees of freedom. Furthermore, because the entangled photons are created with a center wavelength of 1560 nm, our approach can readily be integrated into modern telecommunication infrastructure, thus paving the way for high-rate quantum key distribution and many other entanglement-based quantum communication protocols.
Comprehensive prediction of immune microenvironment and hot and cold tumor differentiation in cutaneous melanoma based on necroptosis-related lncRNA

Published: May 2023

As per research, causing cancer cells to necroptosis might be used as a therapy to combat cancer drug susceptibility. Long non-coding RNA (lncRNA) modulates the necroptosis process in Skin Cutaneous Melanoma (SKCM), even though the precise mechanism by which it does so has yet been unknown. RNA sequencing and clinical evidence of SKCM patients were accessed from The Cancer Genome Atlas database, and normal skin tissue sequencing data was available from the Genotype-Tissue Expression database. Person correlation analysis, differential screening, and univariate Cox regression were successively utilized to identify necroptosis-related hub lncRNAs. Following this, we adopt the least absolute shrinkage and selection operator regression analysis to construct a risk model. The model was evaluated on various clinical characteristics using many integrated approaches to ensure it generated accurate predictions. Through risk score comparisons and consistent cluster analysis, SKCM patients were sorted either high-risk or low-risk subgroups as well as distinct clusters. Finally, the effect of immune microenvironment, m7G methylation, and viable anti-cancer drugs in risk groups and potential clusters was evaluated in further detail. Included USP30-AS1, LINC01711, LINC00520, NRIR, BASP1-AS1, and LINC02178, the 6 necroptosis-related hub lncRNAs were utilized to construct a novel prediction model with excellent accuracy and sensitivity, which was not influenced by confounding clinical factors. Immune-related, necroptosis, and apoptosis pathways were enhanced in the model structure, as shown by Gene Set Enrichment Analysis findings. TME score, immune factors, immune checkpoint-related genes, m7G methylation-related genes, and anti-cancer drug sensitivity differed significantly between the high-risk and low-risk groups. Cluster 2 was identified as a hot tumor with a better immune response and therapeutic effect. Our study may provide potential biomarkers for predicting prognosis in SKCM and provide personalized clinical therapy for patients based on hot and cold tumor classification.
Pancreatic β-cell glutaminase 2 maintains glucose homeostasis under the condition of hyperglycaemia

Published: May 2023

Glutaminase 2 (GLS2), a master regulator of glutaminolysis that is induced by p53 and converts glutamine to glutamate, is abundant in the liver but also exists in pancreatic β-cells. However, the roles of GLS2 in islets associated with glucose metabolism are unknown, presenting a critical issue. To investigate the roles of GLS2 in pancreatic β-cells in vivo, we generated β-cell-specific Gls2 conditional knockout mice (Gls2 CKO), examined their glucose homeostasis, and validated the findings using a human islet single-cell analysis database. GLS2 expression markedly increased along with p53 in β-cells from control (RIP-Cre) mice fed a high-fat diet. Furthermore, Gls2 CKO exhibited significant diabetes mellitus with gluconeogenesis and insulin resistance when fed a high-fat diet. Despite marked hyperglycaemia, impaired insulin secretion and paradoxical glucagon elevation were observed in high-fat diet-fed Gls2 CKO mice. GLS2 silencing in the pancreatic β-cell line MIN6 revealed downregulation of insulin secretion and intracellular ATP levels, which were closely related to glucose-stimulated insulin secretion. Additionally, analysis of single-cell RNA-sequencing data from human pancreatic islet cells also revealed that GLS2 expression was elevated in β-cells from diabetic donors compared to nondiabetic donors. Consistent with the results of Gls2 CKO, downregulated GLS2 expression in human pancreatic β-cells from diabetic donors was associated with significantly lower insulin gene expression as well as lower expression of members of the insulin secretion pathway, including ATPase and several molecules that signal to insulin secretory granules, in β-cells but higher glucagon gene expression in α-cells. Although the exact mechanism by which β-cell-specific GLS2 regulates insulin and glucagon requires further study, our data indicate that GLS2 in pancreatic β-cells maintains glucose homeostasis under the condition of hyperglycaemia.

Published: May 2023

Unravelling protein distributions within individual cells is vital to understanding their function and state and indispensable to developing new treatments. Here we present the Hybrid subCellular Protein Localiser (HCPL), which learns from weakly labelled data to robustly localise single-cell subcellular protein patterns. It comprises innovative DNN architectures exploiting wavelet filters and learnt parametric activations that successfully tackle drastic cell variability. HCPL features correlation-based ensembling of novel architectures that boosts performance and aids generalisation. Large-scale data annotation is made feasible by our AI-trains-AI approach, which determines the visual integrity of cells and emphasises reliable labels for efficient training. In the Human Protein Atlas context, we demonstrate that HCPL is best performing in the single-cell classification of protein localisation patterns. To better understand the inner workings of HCPL and assess its biological relevance, we analyse the contributions of each system component and dissect the emergent features from which the localisation predictions are derived.
Weather anomalies more important than climate means in driving insect phenology
Authors: Guralnick R. P. , Campbell L. P. , Belitz M. W.
Published: May 2023

Studies of long-term trends in phenology often rely on climatic averages or accumulated heat, overlooking climate variability. Here we test the hypothesis that unusual weather conditions are critical in driving adult insect phenology. First, we generate phenological estimates for Lepidoptera (moths and butterflies) across the Eastern USA, and over a 70 year period, using natural history collections data. Next, we assemble a set of predictors, including the number of unusually warm and cold days prior to, and during, the adult flight period. We then use phylogenetically informed linear mixed effects models to evaluate effects of unusual weather events, climate context, species traits, and their interactions on flight onset, offset and duration. We find increasing numbers of both warm and cold days were strong effects, dramatically increasing flight duration. This strong effect on duration is likely driven by differential onset and termination dynamics. For flight onset, impact of unusual climate conditions is dependent on climatic context, but for flight cessation, more unusually cold days always lead to later termination particularly for multivoltine species. These results show that understanding phenological responses under global change must account for unusual weather events, especially given they are predicted to increase in frequency and severity.

Smoke from vegetation fires affects air quality, atmospheric cycling, and the climate in the Amazon rain forest. A major unknown has remained the quantity of long-range transported smoke from Africa in relation to local and regional fire emissions. Here we quantify the abundance, seasonality, and properties of African smoke in central Amazonia. We show that it accounts for ~ 60% of the black carbon concentrations during the wet season and ~ 30% during the dry season. The African smoke influences aerosol-radiation interactions across the entire Amazon, with the strongest impact on the vulnerable eastern basin, a hot spot of climate and land use change. Our findings further suggest that the direct influence of African smoke has been historically relevant for soil fertilization, the carbon and water cycles, and, thus, the development of the Amazon forest ecosystem, even in the pre-industrial era.

Correlations Between Stuttering Severity and Satisfaction With Life, Self-Acceptance, Self-Compassion, and Avoidance in People Who Stutter: Variability by Sources of Support
Authors: Plexico Laura W. , Erath Stephen A.
Published: May 2023

Purpose:

The primary purpose of this study was to evaluate correlations between stuttering severity and satisfaction with life (SWL), self-acceptance (SA), self-compassion (SC), and avoidance among people who stutter (PWS) and did seek support or did not seek support from family, friends, and the National Stuttering Association (NSA).

Method:

This study surveyed 47 self-identified PWS from a larger study in order to obtain information on background, avoidance, SA, SWL, and SC. Correlation analyses were used to examine concurrent associations.

Results:

Stuttering severity was significantly correlated with lower SA and higher avoidance among PWS who did not seek support from friends. Stuttering severity was not significantly correlated with lower SA, lower SC, or higher avoidance among PWS who sought support from friends or family. However, correlations between stuttering severity and lower SWL were similarly strong and significant among PWS who did and did not seek support from friends and from family. Stuttering severity was significantly correlated with lower SA and lower SWL among PWS who sought support from the NSA, but not correlated with these variables among PWS who did not seek support from the NSA.

Conclusions:

Correlations between greater stuttering severity and lowered SWL, SA, SC, and increased avoidance were not reduced with presence of formal support (i.e., NSA) but were nonsignificant with support from friends in some cases. Additional research is needed to address why a person is more or less likely to seek support and the impact support has on the life of the person. The clinical implications involve determining help-seeking behavior and the potential barriers to help-seeking.

Nowadays, the information revolution with digital technology as the core is taking place in the engineering consulting industry. Traditional engineering consulting enterprises should follow the trend and change with the trend, give full play to their long-accumulated knowledge and skills, and realize platform-based and digital transformation. Combining the existing literature research, this paper proposes the platform-based transformation of Chinese traditional engineering consulting enterprises based on dynamic embedding of value chain, and verify it with the platform transformation practice of Glodon Company. Taking environmental perception ability as the basis, relationship and structure debugging as the guarantee, and innovative learning as the driving force, engineering consulting enterprises adopt contingency and active embedding behavior to integrate resources along the value chain, and build a digital intelligence platform at the same time to support the strategic reconstruction of enterprises, form a platform ecology with themselves as the core and multiple subjects participating, complete the value chain leap, and adopt a digital governance system of cooperative governance of multiple subjects in order to maintain the healthy development of the platform ecology.

Authors: Lv Hao , Guo Guanghai
Published: May 2023

College physics not only carries the task of learning basic knowledge for science and technology students, but also plays a deep role in educating students through thinking and politics. It has irreplaceable nurturing functions in cultivating students’ ideals and beliefs, cultivating national sentiments and strengthening scientific thinking. In the process of education and teaching, we insist on the “trinity” education mode of ideologies, mindset and knowledge, cultivating people with ideologies, reshaping people with thinking and enlightening people with knowledge. Thus, we maximize the effect of “teaching” and “learning”. A new form of university physics teaching is built by optimizing teaching resources and reforming the teaching mode, based on the characteristics of the curriculum and the students. Therefore, we realize the knowledge transfer to value leadership from teaching knowledge, and truly implement the fundamental task of moral education.

Due to society's biased perception of coal enterprises, Mining Engineering students’ cultivation faces problems such as students' unwillingness to engage in mining work and the decoupling of graduates' abilities from job demands. The teaching and research team conducted in-depth research and exploration on the cultivation model of applied mining engineering professionals, and constructed a university-enterprise cooperation model for talent cultivation guided by the spirit of "hard work, innovation, unity and selflessness." This model effectively solves the bottleneck of mining engineering talent cultivation in local colleges and universities and meets the new requirements of the current era's development. After years of exploration and practice, mining engineering students not only love enterprises but also significantly improve their comprehensive innovation abilities.

Coal is an important guarantee of energy security, and energy enterprises urgently need a large number of applied technical and management talents who love their jobs and can adapt to the needs of modern industry development. However, the talent cultivation of mining engineering majors has faced problems such as the decoupling of graduates' abilities from job demands due to society's biased perception of coal enterprises [1]. The teaching and research team adheres to the educational philosophy of "demand-oriented, student-centered, and quality-based" and conducts in-depth research and exploration on the talent cultivation model of applied mining engineering professionals. With the establishment and practice of the practical teaching system for cultivating applied mining engineering talents and the construction of an intelligent mining engineering course system for regional coal industry transformation needs, the team has constructed a university-enterprise cooperation model for talent cultivation guided by the spirit of "hard work, innovation, unity, and selflessness."

The Use of Bypassing Treatment Strategies in Hemophilia and Their Effect on Laboratory Testing
Authors: Pruthi Rajiv K. , Chen Dong
Published: May 2023

Factor VIII and IX inhibitors in congenital hemophilia A and B, respectively, neutralize the infused coagulation factor concentrate rendering them ineffective. Bypassing agents (BPAs) that circumvent the block imposed by the inhibitors are used for the prevention and management of bleeding. Activated prothrombin complex concentrate was the original BPA, recombinant activated factor VII was then introduced, and more recently nonfactor agents that target the procoagulant and anticoagulant systems have been developed and are in clinical use (e.g., emicizumab, a bispecific antibody for hemophilia A). Other BPAs are in clinical trials (e.g., fitusiran targets antithrombin, concizumab and marstacimab target tissue factor pathway inhibitor, and SerpinPC targets activated protein C). The BPAs have a varied effect on coagulation assays, and as more patients are exposed to these agents, it is important to be aware of the effects. Herein, we present an overview of the effect of BPAs on routine and specialized coagulation assays including thrombin generation and viscoelastic assays.
The role of peers in promoting energy conservation among Chinese university students
Authors: Lin Boqiang , Jia Huanyu
Published: May 2023

Guiding individuals to adopt pro-environmental behaviors is critical to achieving carbon neutrality goals. Public policy targeted at a small number of people may be amplified by interpersonal interaction, making peer effect a potentially useful tool for accelerating problem solving. However, previous studies have paid insufficient attention to the influence of peers on university students’ energy-saving behaviors. This paper attempts to examine the effect using a large-scale survey dataset conducted on students from Xiamen University in China and the classical linear-in-means model. The result shows that peers’ pro-environmental behaviors have positive effect on individuals. The heterogeneity of the influence and the potential mechanisms are also explored. This paper contributes to very important and still growing literature dealing with contagion processes in pro-environmental behaviors. The policy implication is that the government should make full use of the peer effect to maximize the benefits of energy-conservation campaigns.
