Higher-spin Yang–Mills, amplitudes and self-duality
Authors: Adamo Tim , Tran Tung 
Published: April 2023

AbstractThe existence of interacting higher-spin theories is tightly constrained by many no-go theorems. In this paper, we construct a chiral, higher-spin generalization of Yang–Mills theory in flat space which avoids these no-go theorems and has non-trivial tree-level scattering amplitudes with some higher-spin external legs. The fields and action are complex, so the theory is non-unitary and parity-violating, yet we find surprisingly compact formulae for all-multiplicity tree-level scattering amplitudes in the maximal helicity violating (MHV) sector, where the two negative helicity particles have identical but arbitrary spin. This is possible because the theory admits a perturbative expansion around its self-dual sector. Using twistor theory, we prove the classical integrability of this self-dual sector and show that it can be described on spacetime by an infinite tower of interacting massless scalar fields. We also give a twistor construction of the full theory and use it to derive the formula for the MHV amplitude.

Abstract
Telomere repeat binding proteins (TRBs) belong to a family of proteins possessing a Myb-like domain which binds to telomeric repeats. Three members of this family (TRB1, TRB2, TRB3) from Arabidopsis thaliana have already been described as associated with terminal telomeric repeats (telomeres) or short interstitial telomeric repeats in gene promoters (telo-boxes). They are also known to interact with several protein complexes: telomerase, Polycomb repressive complex 2 (PRC2) E(z) subunits and the PEAT complex (PWOs-EPCRs-ARIDs-TRBs). Here we characterize two novel members of the TRB family (TRB4 and TRB5). Our wide phylogenetic analyses have shown that TRB proteins evolved in the plant kingdom after the transition to a terrestrial habitat in Streptophyta, and consequently TRBs diversified in seed plants. TRB4-5 share common TRB motifs while differing in several others and seem to have an earlier phylogenetic origin than TRB1-3. Their common Myb-like domains bind long arrays of telomeric repeats in vitro, and we have determined the minimal recognition motif of all TRBs as one telo-box. Our data indicate that despite the distinct localization patterns of TRB1-3 and TRB4-5 in situ, all members of TRB family mutually interact and also bind to telomerase/PRC2/PEAT complexes. Additionally, we have detected novel interactions between TRB4-5 and EMF2 and VRN2, which are Su(z)12 subunits of PRC2.

Published: April 2023

AbstractThis study examines science teacher beliefs working in the conflict-affected zones of Jammu and Kashmir. Research in these areas indicates that teacher beliefs influence their classroom practices and student learning outcomes and that teacher beliefs are highly context sensitive. Using data collected from a questionnaire and focussed group discussions, this research elucidates science teachers’ beliefs regarding how conflict affects classroom practices, conflict and teaching issues, the multifaceted role of teachers in conflict-affected zones, the role of science education in ameliorating conflict, and the changing role of teachers during three decades of active conflict in Jammu and Kashmir. A nuanced picture of teacher beliefs originated from this study suggesting that despite challenges teachers are committed to children’s academic, cognitive, and psychosocial growth.
Neutrophil (dys)function due to altered immuno-metabolic axis in type 2 diabetes: implications in combating infections

Published: April 2023

AbstractMetabolic and inflammatory pathways are highly interdependent, and both systems are dysregulated in Type 2 diabetes (T2D). T2D is associated with pre-activated inflammatory signaling networks, aberrant cytokine production and increased acute phase reactants which leads to a pro-inflammatory ‘feed forward loop’. Nutrient ‘excess’ conditions in T2D with hyperglycemia, elevated lipids and branched-chain amino acids significantly alter the functions of immune cells including neutrophils. Neutrophils are metabolically active cells and utilizes energy from glycolysis, stored glycogen and β-oxidation while depending on the pentose phosphate pathway for NADPH for performing effector functions such as chemotaxis, phagocytosis and forming extracellular traps. Metabolic changes in T2D result in constitutive activation and impeded acquisition of effector or regulatory activities of neutrophils and render T2D subjects for recurrent infections. Increased flux through the polyol and hexosamine pathways, elevated production of advanced glycation end products (AGEs), and activation of protein kinase C isoforms lead to (a) an enhancement in superoxide generation; (b) the stimulation of inflammatory pathways and subsequently to (c) abnormal host responses. Neutrophil dysfunction diminishes the effectiveness of wound healing, successful tissue regeneration and immune surveillance against offending pathogens. Hence, Metabolic reprogramming in neutrophils determines frequency, severity and duration of infections in T2D. The present review discusses the influence of the altered immuno-metabolic axis on neutrophil dysfunction along with challenges and therapeutic opportunities for clinical management of T2D-associated infections.

Published: April 2023

ABSTRACT:Background:The COVID-19 pandemic has accelerated the growing global interest in the role of augmented and virtual reality in surgical training. While this technology grows at a rapid rate, its efficacy remains unclear. To that end, we offer a systematic review of the literature summarizing the role of virtual and augmented reality on spine surgery training.Methods:A systematic review of the literature was conducted on May 13th, 2022. PubMed, Web of Science, Medline, and Embase were reviewed for relevant studies. Studies from both orthopedic and neurosurgical spine programs were considered. There were no restrictions placed on the type of study, virtual/augmented reality modality, nor type of procedure. Qualitative data analysis was performed, and all studies were assigned a Medical Education Research Study Quality Instrument (MERSQI) score.Results:The initial review identified 6752 studies, of which 16 were deemed relevant and included in the final review, examining a total of nine unique augmented/virtual reality systems. These studies had a moderate methodological quality with a MERSQI score of 12.1 + 1.8; most studies were conducted at single-center institutions, and unclear response rates. Statistical pooling of the data was limited by the heterogeneity of the study designs.Conclusion:This review examined the applications of augmented and virtual reality systems for training residents in various spine procedures. As this technology continues to advance, higher-quality, multi-center, and long-term studies are required to further the adaptation of VR/AR technologies in spine surgery training programs.
Fundamentals and issues of user experience in the process of designing consumer products

Published: April 2023

Abstract
User experience (UX) application in the practice of engineering and product design is still limited. The present paper provides insights into research on UX design and recommendations for design practitioners by pointing out common criticalities. These outcomes are achieved through a literature review on how UX relates to design. First, issues in benefitting from UX understanding in design are identified with a specific focus on theoretical contributions. Second, experimental papers investigating UX and design are analysed in relation to previously identified issues. Although issues are present to some extent in all the contributions, the empirical studies dealing with UX in design are overall valid. The results highlight UX’s support in revealing design requirements, but its capability of steering design processes is arguable, as concrete guidelines for practitioners are not well described. Based on identified issues, the authors propose a checklist to make UX studies in design more reliable and their outcomes more comparable.

Gilayon and “Apocalypse”: Reconsidering an Early Jewish Concept and Genre
Authors: Kulik Alexander 
Published: April 2023

AbstractThis paper examines various ways in which apocalyptic studies can benefit from the introduction of the term and concept of gilayon, a reconstructed Hebrew counterpart of the Judeo-Greek apocalypse. The term gilayon, which combines the meanings of “revealed book” and “book of revelation,” refers to a central image of early Jewish revealed literature and could serve to define an important corpus, the boundaries of which might well overlap with (but still differ from) what is understood by the “genre apocalypse” in modern research. Moreover, this reconstructed concept uncovers additional meanings and associations, which shed light on texts known as “apocalyptic,” and has explanatory power for many phenomena associated with them. The introduction of gilayon may modify the entire paradigm of our understanding of early Jewish mysticism and help to divert the discussion of textual genres associated with it from a phenomenological to a historical route.
The Kuzari and Early Kabbalah: Between Integration and Interpretation regarding the Secrets of the Sacrificial Rite
Authors: Bar-Asher Avishai 
Published: April 2023

AbstractThe proper place of Judah Halevi’s thought in the initial emergence and subsequent development of medieval kabbalah has been the subject of debate for centuries. The general consensus has it that the Kuzari was not much more than a convenient repository of terms. This study measures the extent of Halevi’s impact on early kabbalah by using the Kuzari’s reasons for the sacrificial rite as a test case.Halevi offered an exoteric, more rationalistic explanation and alluded to an esoteric one. Catalonian kabbalists in fact engaged for generations with these two reasons offered by the Kuzari, displaying a shared yet variable approach to Halevi’s thought. Unsurprisingly, some grabbed the low-hanging fruit by interpreting Halevi’s esoteric reason, which he refused to disclose, in terms of theosophical kabbalah. More unexpected, however, is the possible conceptual indebtedness of the earliest Catalonian kabbalists, like Ezra of Gerona, to Halevi’s theurgic conception of the commandments and doctrine of the Godhead. Of particular interest, too, is the fact that later generations of kabbalists interpreted the Kuzari using paradigms they also employed in their conceptualization of theosophical kabbalah, such as astral magic or neoplatonic psychology and spiritual eschatology.Halevi’s work was not simply scavenged for its well-wrought nomenclature. If one looks closely, evidence for the Kuzari’s significant and lasting imprint can be found throughout kabbalah: in the doctrine of the Godhead, in the theurgic conception of religious ritual, in the development of an esoteric interpretation of religious praxis, in the establishment of an esoteric reading of Sefer yeẓirah, and more.
APPLICATIONAL AMBIGUITY? TAIWAN'S STATUS IN INTERNATIONAL SALES LAW
Authors: Köhler Ben 
Published: April 2023

AbstractThe discussion on Taiwan's status under the United Nations Convention on Contracts for the International Sale of Goods (CISG) has picked up steam. After providing some historical background, it is argued that neither doctrinal nor policy arguments can support the application of the Convention to Taiwanese parties. Drawing on case law in the context of other uniform law treaties, the article concludes that the approbation of the CISG by the People's Republic of China should not bind Taiwan and that, as a consequence, Taiwanese parties should be treated as parties from non-Contracting States.
Government spending preferences over the life cycle
Authors: Vallée-Dubois Florence 
Published: April 2023

AbstractDo seniors have different public spending preferences than younger people? The literature on this topic has been limited so far to a few policies or to short periods of time, which makes it difficult to provide a comprehensive answer to this question. Using data from Canadian surveys conducted between 1987 and 2019 and covering fifteen policies, this paper shows that seniors, as compared to younger adults, are slightly more favourable to the status quo when it comes to government spending. Results also show that support for education spending decreases extensively over the life cycle, while support for environment spending decreases until middle age, then stabilizes. In contrast, support for transportation spending is more widespread in older age, while support for elderly services takes an inverted U-shape over the life cycle. These findings broaden our understanding of the influence of age on government spending preferences and allow us to reflect on the consequences of a growing senior electorate on government budgets.
The materiality of secrets: everyday secrecy in postwar Soviet Union
Authors: Siddiqi Asif A. 
Published: April 2023

AbstractThe intensive culture of secrecy and censorship in postwar Soviet society was enabled by bureaucracies such as Glavlit, the principal agency for censorship, but also by a secondary level of ‘parasitic bureaucracy’ involving institutions and paperwork which drew lifeblood from the core regime of secrecy but had no reason to exist otherwise. In highlighting everyday secrecy at the office (through the ‘first departments’ responsible for workplace secrecy) and in libraries (in the work of special storage units for censored books), this article shows how this parasitic bureaucratic culture of secrecy prioritised the regulation of knowledge in its material and spatial forms.
Reciprocity, Incentives, and Off-Ramps: Faculty–Undergraduate Collaboration and Comparative Politics Research
Authors: Coyoli Julia Smith , Dosh Paul 
Published: April 2023

ABSTRACTWhat are the opportunities and challenges of faculty–undergraduate collaborative scholarship that involves student participation at every stage of the research process? Drawing on interviews with comparative politics faculty members and undergraduate students, this article discusses the themes of reciprocity, incentives, and “off-ramps.” First, we find that an unequal division of labor can give way to a more reciprocal work dynamic as long-term projects unfold. Second, we consider the use of incremental incentives to sustain student motivation. Third, we propose the creation of off-ramps to allow an undergraduate to gracefully exit a project early. Grounded in these themes, we argue that—with a few guardrails—faculty members and undergraduate students can benefit from long-term collaborative research projects, including those that involve fieldwork or that seek to publish peer-reviewed articles.
Impaired cognitive flexibility across psychiatric disorders
Authors: Grant Jon E. , Chamberlain Samuel R. 
Published: April 2023

AbstractObjectiveProblems with cognitive flexibility have been associated with multiple psychiatric disorders, but there has been little understanding of how cognitive flexibility compares across these disorders. This study examined problems of cognitive flexibility in young adults across a range of psychiatric disorders using a validated computerized trans-diagnostic flexibility paradigm. We hypothesized that obsessive-compulsive spectrum disorders (eg, obsessive-compulsive disorder, trichotillomania, and skin-picking disorder) would be associated with pronounced flexibility problems as they are most often associated with irrational or purposeless repetitive behaviors.MethodsA total of 576 nontreatment seeking participants (aged 18-29 years) were enrolled from general community settings, provided demographic information, and underwent structured clinical assessments. Each participant undertook the intra-extra-dimensional task, a validated computerized test measuring set-shifting ability. The specific measures of interest were total errors on the task and performance on the extra-dimensional (ED) shift, which reflects the ability to inhibit and shift attention away from one stimulus dimension to another.ResultsParticipants with depression and PTSD had elevated total errors on the task with moderate effect sizes; and those with the following had deficits of small effect size: generalized anxiety disorder (GAD), obsessive-compulsive disorder (OCD), antisocial personality disorder, and binge-eating disorder. For ED errors, participants with PTSD, GAD, and binge-eating disorder exhibited deficits with medium effect sizes; those with the following had small effect size deficits: depression, social anxiety disorder, OCD, substance dependence, antisocial personality disorder, and gambling disorder.ConclusionsThese data indicate cognitive flexibility deficits occur across a range of mental disorders. Future work should explore whether these deficits can be ameliorated with novel treatment interventions.
Countering self-protection interrupted sampling repeater jammer against chirp radar
Authors: Baher Safa Hanbali Samer 
Published: April 2023

AbstractInterrupted sampling repeater jammer generates multiple false targets to confuse chirp radar systems. In practical situations, maintaining separation between true target echo and jamming signal is not possible because the jamming pulses and the true target echo are overlapping in both time and frequency domains. A new anti-jamming technique against interrupted sampling jamming of self-protection repeater jammer is proposed without the knowledge of the jamming parameters. The proposed technique is based on fractional Fourier transform that can separate the overlapping true target echo and jamming pulses in the fractional domain, and then the resulting pulses are returned to the time domain, the true target can be easily distinguished from the false ones because the jamming pulses lag behind the true target echo by the jammer's delay. The theoretical analysis and simulation results demonstrate the efficiency and validity of the proposed technique.
Tracing the Rain Formation Pathways in Numerical Simulations of Deep Convection
Authors: Beydoun Hassan , Caldwell Peter M. , Stein Elizabeth V. , Wharton Sonia 
Published: April 2023

AbstractQuantifying the microphysical process contributions to surface precipitation in numerical simulations can be challenging. This is due to the fact that many microphysical processes contribute to the formation and depletion of rain drops and there is almost always a spatial/temporal mismatch between where/when rain is formed and where/when it strikes the surface. In this work, we develop a tracing method that tracks the sources and sinks of raindrop mass and number as they are advected by the Weather Research and Forecasting model. Applying the method to an idealized squall line confirms that convective precipitation is dominated by warm rain processes (autoconversion and accretion) while stratiform precipitation is dominated by the melting of rimed and unrimed ice crystals. Sensitivity experiments in which the prescribed cloud drop number concentration is increased confirm the conventional wisdom that weakened autoconversion increases the fraction of raindrops originating from cold rain processes. The method also reveals that when applied to deep convection the Khairoutdinov and Kogan autoconversion scheme produces an excessive number of raindrops which are subsequently clipped in P3 microphysics to keep the rain size distribution within prescribed limits. This problem can mostly be mitigated by increasing the assumed radius for raindrops created by autoconversion.

AbstractDisturbed gut microbiota is a potential factor in the pathogenesis of major depressive disorder (MDD), yet whether gut microbiota dysbiosis is associated with the severity of MDD remains unclear. Here, we performed shotgun metagenomic profiling of cross-sectional stool samples from MDD (n = 138) and healthy controls (n = 155). The patients with MDD were divided into three groups according to Hamilton Depression Rating Scale 17 (HAMD-17), including mild (n = 24), moderate (n = 72) and severe (n = 42) individuals, respectively. We found that microbial diversity was closely related to the severity of MDD. Compared to HCs, the abundance of Bacteroides was significantly increased in both moderate and severe MDD, while Ruminococcus and Eubacterium depleted mainly in severe group. In addition, we identified 99 bacteria species specific to severity of depression. Furthermore, a panel of microbiota marker comprising of 37 bacteria species enabled to effectively distinguish MDD patients with different severity. Together, we identified different perturbation patterns of gut microbiota in mild-to-severe depression, and identified potential diagnostic and therapeutic targets.
