Published: February 2023

AbstractWe focus our attention on the newly proposed X-ray binary system HD 3191 whose nature still lacks dynamical confirmation and accurate orbital parameters. The positional agreement of this object with a flaring gamma-ray source was the original motivation of this work, although the present chances of association are reduced. A long-term spectroscopic monitoring of HD3191 was conducted using the 1-m class, robotic, Joan Oró telescope at the Observatori Astronòmic del Montsec facilities, located in the pre-Pyrenees mountains 140 km away from Barcelona. The Doppler measurements suggest an agreement with the previously reported 16.09 d photometric period, as expected. We also present a very preliminary radial velocity curve based on a circular orbit solution that hints to a low velocity amplitude. Nevertheless, the instrumental limitations of our data render necessary to carry out improved spectroscopic observations to better discriminate among the nature of the compact companion.
An empowerment-based solution to robotic manipulation tasks with sparse rewards
Authors: Dai Siyu , Xu Wei , Hofmann Andreas , Williams Brian 
Published: February 2023

AbstractIn order to provide adaptive and user-friendly solutions to robotic manipulation, it is important that the agent can learn to accomplish tasks even if they are only provided with very sparse instruction signals. To address the issues reinforcement learning algorithms face when task rewards are sparse, this paper proposes an intrinsic motivation approach that can be easily integrated into any standard reinforcement learning algorithm and can allow robotic manipulators to learn useful manipulation skills with only sparse extrinsic rewards. Through integrating and balancing empowerment and curiosity, this approach shows superior performance compared to other state-of-the-art intrinsic exploration approaches during extensive empirical testing. When combined with other strategies for tackling the exploration challenge, e.g. curriculum learning, our approach is able to further improve the exploration efficiency and task success rate. Qualitative analysis also shows that when combined with diversity-driven intrinsic motivations, this approach can help manipulators learn a set of diverse skills which could potentially be applied to other more complicated manipulation tasks and accelerate their learning process.
The Political Salience of Animal Protection in the Netherlands (2012–2021) and Belgium (2010–2019): What do Dutch and Belgian Political Parties Pledge on Animal Welfare and Wildlife Conservation?
Authors: Hus Annick , McCulloch Steven P. 
Published: February 2023

AbstractThe Netherlands and Belgium are European Union (EU) states with a shared border and cultural similarities. Article 13 of the EU Treaty of Lisbon recognises animals as sentient beings. EU laws protect animal welfare and conservation, and member states can implement more stringent legislation. Political salience refers to the extent to which citizens are concerned about political issues. Issue salience can be measured by assessing references to animal protection in party political manifestos. This research analyses the political salience of animal protection in the Netherlands and Belgium. It analyses over 2600 statements on animal protection in Dutch (2012–2021) and Belgian (2010–2019) party manifestos across three consecutive national elections. Quantitative analysis reveals that in both the Netherlands and Belgium, animal protection became more salient during successive elections, with the total number of positive statements increasing and the total number of negative statements decreasing. Farmed animal welfare and wildlife/biodiversity were the most salient issues, although the focus in countries and regions differed. Dutch parties and those in the Walloon region of Belgium focused on farmed animal health and unnecessary suffering; Flemish parties stressed intensive agriculture and animal welfare. In Belgium, wildlife/biodiversity statements stressed the protection of local species; Dutch statements were strongly linked to agriculture. In both the Netherlands and Belgium, left-wing parties had more progressive policy statements, whilst right-wing parties prioritised economic prosperity over animal protection. This research provides the first academic analysis of animal protection policies in political manifestos in the Netherlands and Belgium.
Finding Normal Binary Floating-Point Factors Efficiently

AbstractSolving the floating-point equation $$x \otimes y = z$$

x

z

, where x, y and z belong to floating-point intervals, is a common task in automated reasoning for which no efficient algorithm is known in general. We show that it can be solved by computing a constant number of floating-point factors, and give a fast algorithm for computing successive normal floating-point factors of normal floating-point numbers in radix 2. This leads to an efficient procedure for solving the given equation, running in time of the same order as floating-point multiplication.
A Reduced Basis Method for Darcy Flow Systems that Ensures Local Mass Conservation by Using Exact Discrete Complexes
Authors: Boon Wietse M. , Fumagalli Alessio 
Published: February 2023

AbstractA solution technique is proposed for flows in porous media that guarantees local conservation of mass. We first compute a flux field to balance the mass source and then exploit exact co-chain complexes to generate a solenoidal correction. A reduced basis method based on proper orthogonal decomposition is employed to construct the correction and we show that mass balance is ensured regardless of the quality of the reduced basis approximation. The method is directly applicable to mixed finite and virtual element methods, among other structure-preserving discretization techniques, and we present the extension to Darcy flow in fractured porous media.
Purification, characterization, immobilization and applications of an enzybiotic β-1,3–1,4-glucanase produced from halotolerant marine Halomonas meridiana ES021

Published: February 2023

Abstract
Extracellular β-1,3–1,4-glucanase-producing strain Halomonas meridiana ES021 was isolated from Gabal El-Zeit off shore, Red Sea, Egypt. The Extracellular enzyme was partially purified by precipitation with 75% acetone followed by anion exchange chromatography on DEAE-cellulose, where a single protein band was determined with molecular mass of approximately 72 kDa. The Km value was 0.62 mg β-1,3–1,4-glucan/mL and Vmax value was 7936 U/mg protein. The maximum activity for the purified enzyme was observed at 40 °C, pH 5.0, and after 10 min of the reaction. β-1,3–1,4-glucanase showed strong antibacterial effect against Bacillus subtilis, Streptococcus agalactiae and Vibrio damsela. It also showed antifungal effect against Penicillium sp. followed by Aspergillus niger. No toxicity was observed when tested on Artemia salina. Semi-purified β-1,3–1,4-glucanase was noticed to be effective in clarification of different juices at different pH values and different time intervals. The maximum clarification yields were 51.61% and 66.67% on mango juice at 40 °C and pH 5.3 for 2 and 4 h, respectively. To our knowledge, this is the first report of β-1,3–1,4-glucanase enzyme from halotolerant Halomonas species.

An Exploratory Analysis of Differential Prescribing of High-Risk Opioids by Insurance Type Among Patients Seen by the Same Clinician
Authors: Schulson Lucy B. , Dick Andrew , Sheng Flora , Stein Bradley D. 
Published: February 2023

Abstract
Background
Insurance status may influence quality of opioid analgesic (OA) prescribing among patients seen by the same clinician.

Objective
To explore how high-risk OA prescribing varies by payer type among patients seeing the same prescriber and identify clinician characteristics associated with variable prescribing

Design
Retrospective cohort study using the 2016–2018 IQVIA Real World Data – Longitudinal Prescription

Participants
New OA treatment episodes for individuals ≥ 12 years, categorized by payer and prescriber. We created three dyads: prescribers with ≥ 10 commercial insurance episodes and ≥ 10 Medicaid episodes; ≥ 10 commercial insurance episodes and ≥ 10 self-pay episodes; and ≥ 10 Medicaid episodes and ≥ 10 self-pay episodes.

Main Outcome(s) and Measure(s)
Rates of high-risk episodes (initial opioid episodes with > 7-days’ supply or prescriptions with a morphine milliequivalent daily dose >90) and odds of being an unbalanced prescriber (prescribers with significantly higher percentage of high-risk episodes paid by one payer vs. the other payer)

Key Results
There were 88,352 prescribers in the Medicaid/self-pay dyad, 172,392 in the Medicaid/commercial dyad, and 122,748 in the self-pay/commercial dyad. In the Medicaid/self-pay and the commercial-self-pay dyads, self-pay episodes had higher high-risk episode rates than Medicaid (16.1% and 18.4%) or commercial (22.7% vs. 22.4%). In the Medicaid/commercial dyad, Medicaid had higher high-risk episode rates (21.1% vs. 20.4%). The proportion of unbalanced prescribers was 11–12% across dyads. In adjusted analyses, surgeons and pain specialists were more likely to be unbalanced prescribers than adult primary care physicians (PCPs) in the Medicaid/self-paydyad (aOR 1.2, 95% CI 1.16–1.34 and aOR 1.2, 95% CI 1.03–1.34). For Medicaid/commercial and self-pay/commercial dyads, surgeons had lower odds of being unbalanced compared to PCPs (aOR 0.6, 95% CI 0.57–0.66 and aOR 0.6, 95% CI 0.61–0.68).

Conclusions
Clinicians prescribe high-risk OAs differently based on insurance type. The relationship between insurance and opioid prescribing quality goes beyond where patients receive care.
Hydrogen Diffusion and Trapping in Low-Alloy Tempered Martensitic Steels
Authors: Cupertino-Malheiros L. , Oudriss A. , Thébault F. , Piette M. , Feaugas X. 
Published: February 2023

AbstractStructural characterization of ten low-alloy tempered martensitic steels of varied composition (C, Cr, Mo, Mn, and V contents) and tempering temperature was performed to question the impact of microstructural features on hydrogen state. Thermal desorption spectroscopy and electrochemical permeation data for each alloy were acquired and interpreted in view of hydrogen diffusion/trapping models. This large database provided precise information regarding solubility, diffusion coefficient, activation energies for diffusion and trapping, hydrogen distribution into lattice, and reversible and irreversible trap sites. The results reveal a tendency for the apparent diffusion coefficient to decrease with increasing yield strength, mainly related to the density of trap sites rather than lattice diffusion. Estimates of trapping at dislocation core could explain the irreversible trapping in the six steels with sub-surface hydrogen concentration smaller than 1.5 wppm. For the four steels with higher solubility, it was calculated the superabundant vacancies concentration necessary to justify the amount of trapping sites. The steel with the highest Mo and V contents presented superior solubility of trapped hydrogen which was related to its precipitation of few nanometers in size. It was considered irreversible trapping at carbon vacancies as well as reversible trapping at elastic strain fields around the detected MC carbides.

Show no quarter: combating plausible lies with ex-ante honesty oaths
Authors: Babin J. Jobu , Chauhan Haritima S. 
Published: February 2023

AbstractMisreporting—a form of lying—is common in online labor and remote work settings. We execute an experiment on Amazon MTurk to determine how ex-ante honesty oaths and worker beliefs impact lying behavior across a range of plausible and implausible lies. Using a novel quantile-style exposition of the types of lies reported, we find that oaths elicit more truthful behavior, reducing both small, plausible lies and large, implausible ones. Shirking is reduced under oath. Worker expectations of group reporting are positively related to individual reporting of plausible lies.
Muslim Religiosity and Juvenile Delinquency: A Systematic Review
Authors: Mohammad Taufik , Banse Rainer 
Published: February 2023

AbstractWhile discussion of religiosity and delinquency has garnered attention in the past few decades, few studies have focused on how religiosity influences rates of delinquency among Muslim adolescents. In this systematic review, keywords were used to cull pertinent articles from two major databases (Scopus and EBSCOhost). In total, 14 articles were identified based on several inclusion criteria. In general, the studies selected showed that Muslim adolescents have a lower rate of delinquency compared to non-Muslim adolescents. However, when questions related to the measurement of delinquency (such as including violence) and the cultural context (such as including individuals who are first-generation immigrants of a non-Muslim-majority country) are taken into consideration, more complex trends are observed. Furthermore, many identified articles did not capture the essence of Muslim religiosity as conceptualized by some Muslim researchers, which has specific and unique properties that must be considered. This study demonstrates how Muslim religiosity protects against delinquency and has a potential use for intervention with Muslim adolescents.
Why does Faithful Epistemic Representation Matter for Management Practices? The Case of the Natural Environment in Management Theory
Authors: Hiquet Rose , Wordley Claire , Ansari Shahzad 
Published: February 2023

AbstractManagement theory is a diverse field where multiple theoretical perspectives coexist and coevolve, leading to conceptual pluralism. While conceptual pluralism is useful for grasping different aspects of the complex reality we live in, it may limit the further development of knowledge on elemental concepts. In this article, we focus on knowledge on the natural environment (NE) in management theory. We argue that management scholars and practitioners often rely on theoretical lenses that tend to reify the NE, thereby limiting the conceptualization of some of the essential properties of the NE. Drawing on the example of the conceptual development of the ecosystem services (ES) at the intersection of economics and biology, we identify the advantages and the limits of interdisciplinary theory-building and testing. Finally, we discuss how tools from the philosophy of science can be useful for proposing a way forward for integrating reliable knowledge on the natural environment in management theory.
Rate and risk factors for pediatric cervical spine fusion pseudarthrosis: opportunity for improvement
Authors: Compton Edward , Illingworth Kenneth D. , Stephan Stephen , Skaggs David L. , Andras Lindsay M. 
Published: February 2023

Abstract
Purpose
Although the pediatric population typically has a high union rate, the cervical spine has a reputation for frequent pseduarthrosis, as high as 38% in some prior series. Our purpose was to examine the rate and risk factors for pseudarthrosis in pediatric cervical spine fusions.

Methods
Retrospective review of all patients with ≥ 2 years follow-up undergoing cervical spinal fusion between January 2004 and December 2019 at a tertiary pediatric hospital. Pseudarthrosis was defined as an absence of radiographic union as assessed by the attending surgeon for which revision surgery was performed.

Results
64 patients (mean age: 8.4 ± 4.7 years) met inclusion criteria. Mean follow-up was 63.3 ± 41.4 months (range: 24–187 months). 28 fusions (44%) included the occiput. 41 patients (64%) had instrumentation, while 23 patients (36%) had uninstrumented fusions. 48 (75%) patients had a halo for a mean of 97.6 ± 49.5 days. The incidence of pseudarthrosis was as follows: overall = 8/64 (12.5%); posterior fusion = 14.8% (8/54); anterior fusions = 0% (0/4); and anteroposterior fusions = 0% (0/6). The rate of pseudarthrosis was over 8 times higher in fusions involving the occiput (occipitocervical fusion: 25.0%; 7/28 vs. cervical alone: 2.8%; 1/36; p = 0.02). Although not statistically significant, the rate of pseudarthrosis was 3 times higher in uninstrumented fusions (21.7%; 5/23) than instrumented fusions (7.3%; 3/41) (p = 0.12). In patients with uninstrumented fusion to the occiput, pseudarthrosis rate was 35.7% (5/14), which was higher compared to those who did not (6.0%; 3/50) (p = 0.01). Incidence of pseudarthrosis was similar in patients who received autograft (13.0%; 7/54) compared to allograft alone (10.0%; 1/10) (p > 0.999).

Conclusions
The pseudarthrosis rate in pediatric cervical spine fusions remained high despite frequent use of halo immobilization and autograft. Patients with uninstrumented occipitocervical fusions are at particularly high risk with more than 1 in 3 developing a pseudarthrosis.

The origin of pigment-binding differences in CP29 and LHCII: the role of protein structure and dynamics
Authors: Elias Eduard , Liguori Nicoletta , Croce Roberta 
Published: February 2023

AbstractThe first step of photosynthesis in plants is performed by the light-harvesting complexes (LHC), a large family of pigment-binding proteins embedded in the photosynthetic membranes. These complexes are conserved across species, suggesting that each has a distinct role. However, they display a high degree of sequence homology and their static structures are almost identical. What are then the structural features that determine their different properties? In this work, we compared the two best-characterized LHCs of plants: LHCII and CP29. Using molecular dynamics simulations, we could rationalize the difference between them in terms of pigment-binding properties. The data also show that while the loops between the helices are very flexible, the structure of the transmembrane regions remains very similar in the crystal and the membranes. However, the small structural differences significantly affect the excitonic coupling between some pigment pairs. Finally, we analyzed in detail the structure of the long N-terminus of CP29, showing that it is structurally stable and it remains on top of the membrane even in the absence of other proteins. Although the structural changes upon phosphorylation are minor, they can explain the differences in the absorption properties of the pigments observed experimentally.

Ambulantes Verordnungsverhalten von Antibiotika und Einstellung zum Verordnungsfeedback
Authors: Mentzel Anja , Maun Andy 
Published: February 2023

Zusammenfassung
Hintergrund
In der ambulanten Patientenversorgung in Deutschland besteht bei Antibiotikaverordnungen für gängige Infektionskrankheiten Optimierungspotenzial, um der Entwicklung von Antibiotikaresistenzen und Risiken durch Nebenwirkungen entgegenzuwirken. Dies betrifft auch Hausarztpraxen. Ein Verordnungsfeedback zeigte in internationalen Studien Potenzial, ist aber in Deutschland kaum etabliert. Ziel dieser qualitativen Studie war es, die Einflüsse von situativen und systembedingten Faktoren auf das Antibiotikaverordnungsverhalten von deutschen Hausärztinnen und Hausärzten zu untersuchen. Ein Fokus lag dabei auf Leitlinien sowie dem Einsatz von Verordnungsfeedbacks.

Methoden
Es wurden 11 Leitfadeninterviews geführt, transkribiert und in Anlehnung an die qualitative Inhaltsanalyse nach Kuckartz ausgewertet. Zur Qualitätssicherung wurde sich an den COREQ-Kriterien („consolidated criteria for reporting qualitative research“) von Tong et al. orientiert.

Ergebnisse
Die Ergebnisse weisen auf eine Diskrepanz zwischen Absicht und tatsächlichem Handeln („intention–behaviour gap“) als mögliche Ursache inadäquater Verordnungen trotz eines hohen Problembewusstseins hin. Diese wird durch unterschiedliche im Praxisallalltag auftretende Spannungsfelder begünstigt. Es wurde eine hausärztliche Kultur der Autonomie deutlich, die bei bestehenden Freiheiten und Belastungen über verschiedene innere Prozesse und Erfahrungen eine Ambivalenz zum Verordnungsfeedback zu begünstigen scheint. Davon lassen sich auch Ansatzpunkte zur Begegnung von Resistenzen sowie Implikationen für Akzeptanzkriterien eines möglichen Feedbacks ableiten. Insbesondere die Skepsis gegenüber Vergleichsdarstellungen im Sinne einer „peer comparison“ verdeutlicht eine Assoziation externer Rückmeldungen mit Maßregelungen und legt einen ein „Peer-based“-Ansatz mit Betonung der kollegialen und individuellen Unterstützung nahe.

Schlussfolgerungen
Künftige Untersuchungen sollten beide Ansätze gegenüberstellen und eine mögliche Integration prüfen. Ferner sollte das Ausmaß tatsächlicher auffälliger Verordnungen und der „intention–behaviour gap“, z. B. in gemischt quantitativ-qualitativen Untersuchungen, genauer abgeschätzt werden.

AbstractTo meet the increasing communication demands, the satellites need to be equipped with the high-accuracy and large-aperture antennas. One of the effective methods to construct the modular antennas with ultra-high accuracy and ultra-large aperture is on-orbit assembly technology. During the on-orbit assembly missions, the assembly error is a key factor to affect the surface accuracy of the modular antennas. This paper studies the node design of each module and the assembly error analysis of the modular antennas. A design method of the module nodes is presented with consideration of the assembly gap between two modules. Meanwhile, a soft connection mechanism is designed to ensure the mobility among the assembly modules. To investigate the transmission law of the assembly errors, an analytical model of assembly error is derived based on the exponential product method. In order to establish the deformation surface with rotation and displacement assembly errors, an error ball concept is proposed by the analytical model. To decrease the assembly errors, the actuators are installed among some modules. Moreover, an adjustment method is proposed to obtain the adjustment amounts of actuators. Finally, the correctness of analytical model and the effectiveness of the adjustment method are demonstrated by the numerical simulations.
Constitution-Making as a Technique of International Law: Reconsidering the Post-war Inheritance
Authors: Saunders Anna 
Published: February 2023

AbstractOver the last three decades, international lawyers and institutions have come to understand constitution-making as an accepted technique of international law and a means of delivering peace and security. In defending this technique from its critics, scholars have drawn on a particular tradition of constitution-making that understands constitutionalism as a lawful form of international action, realizable through a set of formal practices, and juridically distinct from material concerns. This Article explores the building of this tradition through the work of legal scholars within the United States in conversation with German and Jewish émigré scholars and argues that reimagining constitutionalism for the coming decades requires rethinking this separation between the juridical and the material, as well as asking what constitutionalism demands of the laws governing the global economy.
