Quantum networks play a crucial role in distributed quantum information processing, enabling the establishment of entanglement and quantum communication among distant nodes. Fundamentally, networks with independent sources allow for new forms of nonlocality, beyond the paradigmatic Bell’s theorem. Here we implement the simplest of such networks—the bilocality scenario—in an urban network connecting different buildings with a fully scalable and hybrid approach. Two independent sources using different technologies—a quantum dot and a nonlinear crystal—are used to share a photonic entangled state among three nodes connected through a 270 m free-space channel and fiber links. By violating a suitable nonlinear Bell inequality, we demonstrate the nonlocal behavior of the correlations among the nodes of the network. Our results pave the way towards the realization of more complex networks and the implementation of quantum communication protocols in an urban environment, leveraging the capabilities of hybrid photonic technologies.

Lithium niobate on insulator (LNOI) has become an intriguing platform for integrated photonics for applications in communications, microwave photonics, and computing. Whereas, integrated devices including modulators, resonators, and lasers with high performance have been recently realized on the LNOI platform, high-speed photodetectors, an essential building block in photonic integrated circuits, have not been demonstrated on LNOI yet. Here, we demonstrate for the first time, heterogeneously integrated modified uni-traveling carrier photodiodes on LNOI with a record-high bandwidth of 80 GHz and a responsivity of 0.6 A/W at a 1550-nm wavelength. The photodiodes are based on an n-down InGaAs/InP epitaxial layer structure that was optimized for high carrier transit time-limited bandwidth. Photodiode integration was achieved using a scalable wafer die bonding approach that is fully compatible with the LNOI platform.
Estimating the differences in Caesarean section (C-section) rates between public and privately insured mothers in Florida: A decomposition approach
Authors: Puro Neeraj , Kelly Reena J. , Bodas Mandar , Feyereisen Scott 
Published: April 2022

Background
Caesarean section (C-sections) is a medically critical and often life-saving procedure for prevention of childbirth complications. However, there are reports of its overuse, especially in women covered by private insurance as compared to public insurance. This study evaluates the difference in C-Section rates among nulliparous women in Florida hospitals across insurance groups and quantifies the contribution of maternal and hospital factors in explaining the difference in rates.

Methods
We used Florida’s inpatient data provided by the Florida Agency for HealthCare Administration (FLAHCA) and focused on low-risk births that occurred between January 1, 2010, and September 30, 2015. A Fairlie decomposition method was performed on cross-sectional data to decompose the difference in C-Section rates between insurance groups into the proportion explained versus unexplained by the differences in observable maternal and hospital factors.

Results
Of the 386,612 NTSV low-risk births, 72,984 were delivered via C-Section (18.87%). Higher prevalence of C-section at maternal level was associated with diabetes, hypertension, and the expectant mother being over 35 years old. Higher prevalence of C-section at the hospital level was associated with lower occupancy rate, presence of neonatal ICU (NICU) unit and higher obstetrics care level in the hospital. Private insurance coverage in expectant mothers is associated with C-section rates that were 4.4 percentage points higher as compared to that of public insurance. Just over 33.7% of the 4.4 percentage point difference in C-section rates between the two insurance groups can be accounted for by maternal and hospital factors.

Conclusions
The study identifies that the prevalence of C-sections in expectant mothers covered by private insurance is higher compared to mothers covered by public insurance. Although, majority of the difference in C-Section rates across insurance groups remains unexplained (around 66.3%), the main contributor that explains the other 33.7% is advancing maternal age and socioeconomic status of the expectant mother. Further investigation to explore additional factors that explain the difference needs to be done if United States wants to target specific policies to lower overall C-Section rate.

This draft clinical practice guideline for the diagnosis, treatment and prevention of vitamin D deficiency is an update from a previous 2016 document. An analysis of the relevant literature data was carried out, with particular attention to meta-­analyzes, randomized clinical trials and systematic reviews published over the past 5 years. The updated recommendations were discussed and revised by the leading endocrinologists of the Russian Federation, who have expert status in this issue.The classification of 25(OH)D levels has been revised (in particular, the target range of 25(OH)D values has been specified), recommendations have been developed for screening of the disorders associated with vitamin D deficiency. The concept of vitamin D-associated toxicity and recommendations for its diagnosis and prevention have been introduced. Also, indications for the assessment of other vitamin D metabolites besides 25(OH)D, the main marker of vitamin D status, have been indicated.The section regarding treatment of vitamin D deficiency has been expanded and corrected. The major additions concerned the replenishment of the vitamin D deficiency and insufficiency in certain categories of patients (particularly, in the presence of the chronic kidney disease and autoimmune diseases, as well as in pregnant women) and monitoring of the effectiveness and safety of the therapy. The indications for prescribing active metabolites of vitamin D have been adjusted. Recommendations for the prevention of vitamin D deficiency in the general population have also been revised, taking into account large randomized clinical trials, meta-analyzes and systematic reviews of recent years.This publication is an expanded version of the federal guidelines.

Authors: Vierkant Paul , Schrader Antonia , Pampel Heinz 
Published: April 2022

Zusammenfassung
Ein Persistent Identifier (PID) für wissenschaftliche Organisationen wie Forschungseinrichtungen oder Forschungsförderorganisationen ist ein weiteres entscheidendes Puzzlestück zur Förderung der Standardisierung im wissenschaftlichen Publikationsprozess – insbesondere im Hinblick auf den bereits etablierten Digital Object Identifier (DOI) für wissenschaftliche Werke und der ORCID-ID für wissenschaftliche Autor*innen. Die Anwendung dieser PIDs ermöglicht automatisierte Datenflüsse und garantiert die dauerhafte Verknüpfung von Informationsobjekten. Darüber hinaus sind PIDs elementare Bestandteile zur Umsetzung von Open Science. So kommt z. B. der Anwendung eines PID für wissenschaftliche Organisationen bei der Analyse von Publikationen und Kosten der Open-Access-Transformation an einer Einrichtung eine zentrale Bedeutung zu. Um mehr über den Status quo der Nutzung und Verbreitung von Organisations-IDs in Deutschland zu erfahren, wurde im Rahmen des DFG-geförderten Projekts ORCID DE im Zeitraum vom 13.07.2020 bis zum 04.12.2020 eine „Umfrage zum Bedarf und Nutzung von Organisations-IDs an Hochschulen und außeruniversitären Forschungseinrichtungen in Deutschland“ unter 548 wissenschaftlichen Einrichtungen in Deutschland durchgeführt. An der bislang größten Befragung zu Organisations-IDs in Deutschland beteiligten sich 183 Einrichtungen. Bestandteil der Studie waren unter anderem Fragen zur Kenntnis, Verbreitung und Nutzung von Organisations-IDs an wissenschaftlichen Einrichtungen. Darüber hinaus wurden Anforderungen an Organisations-IDs bzw. ihre Metadaten (z. B. Relationen und Granularität) erfragt. Der vorliegende Beitrag bietet einen umfassenden Überblick über die Ergebnisse der im Rahmen des Projekts durchgeführten Umfrage und stellt einen Beitrag zur Förderung und zu einer gesteigerten Bekanntheit von Organisations-IDs dar.

Abstract

Objectives

Cnidoscolus aconitifolius have been investigated to have abundant phytochemicals. However, study on the effect of Cnidoscolus aconitifolius on neurobehavioral performance when supplemented with diet is lacking. The study is aimed at investigating the memory-enhancing effect of Cnidoscolus aconitifolius-supplemented diet (CAD) using Morris water maze and Novel object recognition test.

Methods
Ninety male Wistar rats (80–100 g) were fed with CAD (1, 2.5, 5 and 10%) continuously for a period of 4, 8 and 12 weeks respectively. Six animals per group were used for assessment of memory performance (Morris water maze [MWM] and Novel object recognition test [NORT]); afterwards the brain tissues were harvested for malondialdehyde (MDA), glutathione (GSH) and catalase (CAT) estimation. Acetylcholinesterase (AChE) concentration was also determined. Hippocampal architectural change in the neuron was examined using hematoxylin and eosin (H&E) and cresyl fast violet (Nissl) stain.

Results
Higher percentage of CAD significantly (p<0.05) improve memory performance with time-dependent effects in rats fed with CAD on MMW and NORT. MDA significantly (p<0.05) reduce in 1 and 2.5% CAD groups at 4th weeks and in 2.5 and 5% CAD groups at 8th weeks while GSH concentration significantly (p<0.05) increase at 12th weeks in 2.5 and 10% CAD groups. However, CAT concentration significantly (p<0.05) increase in 2.5, and 5%, CAD groups, 1, 5, and 10% CAD groups and in 5, and 10% CAD groups at 4th, 8th and 12th weeks. AChE significantly (p<0.05) reduce at 4th and 12th weeks. Histological assessment reveals no neuronal and pyramidal degeneration (chromatolysis) at the hippocampal Cornu Ammonis 3 (CA3) region.

Conclusions
The results suggest that CAD boost memory performance in rats through positive modulation of oxidative stress, cholinergic system and degeneration of hippocampal neurons.

Published: April 2022

Abstract

Objectives
The purpose of this paper is to summarize the current evidence on probiotics’ uses as an adjuvant for ulcerative colitis (UC) and provide an understanding of the effect of probiotics supplement on the immune system and inflammatory responses among UC patients and subsequent therapeutic benefits.

Content
A narrative review of all the relevant published papers known to the author was conducted.

Summary
UC is a chronic inflammatory bowel disease (IBD) that results in inflammation and ulceration of the colon and rectum. The primary symptoms of active disease are diarrhea, abdominal pain, and rectal bleeding. About 70% of the human immune system (mucosal-associated lymphoid tissue) originates in the intestine. Probiotics are live microorganisms that help in stabilizing the gut microbiota (nonimmunologic gut defense), restores normal flora, and enhance the humoral immune system. Probiotics especially Bifidobacterium, Saccharomyces boulardii, and lactic acid-producing bacteria have been used as an adjunct therapy for treating UC to ameliorate disease-related symptoms and reduce relapse rate. Probiotics, in general, modulate the immune system through their ability to enhance the mucosal barrier function, or through their interaction with the local immune system to enhance regulatory T cell responses, decrease the pro-inflammatory cytokines such as tumor necrosis factor alpha and interleukin 1 beta and increase anti-inflammatory factor interleukin 10.

Outlook
More studies are needed to explore the properties of the various probiotic bacterial strains, their different uses, as well as the dosage of probiotics and duration for treating different disorders. Further clinical investigations on mechanisms of action and how probiotics modulate the immune system may lead to further advances in managing IBD.
Phase constituents near the center of the Co–Cr–Fe–Ni–Ti system at 1000 °C

Published: April 2022

Abstract
The phase constituents of Co–Cr–Fe–Ni–Ti alloys at 1000 °C, with Cr and Fe each fixed at 20 at.%, were investigated using X-ray diffraction and scanning electron microscopy coupled with energy dispersive X-ray spectroscopy. A series of alloys were prepared via the arc-melting method and annealed at 1000 °C for 30 d. None of the alloys were in the single-phase region. The σ- and χ-(Cr13Fe35Ni3Ti7) phases were confirmed to exist in the center of the system. The alloys with more than 15 at.% Ti were composed of two or more intermetallic phases, and no fcc solid solution was present. Eight phase regions were found near the center of the Co–Cr–Fe–Ni–Ti system, i.e., fcc + D024, fcc + D024 + σ, σ + D024 + C14, fcc + D024 + σ + χ(Cr13Fe35Ni3Ti7), D024 + σ + χ + C14, bcc + D024 + C14, D024 + C14 + bcc + B2 and fcc + C15 + fcc#2. All detected phases contained 5 elements and had their own unique compositions. Moreover, comparing the experimental results with thermodynamic calculations based on the PANHEA database showed that the present database cannot satisfactorily predict the phase constituents in the center of the Co–Cr–Fe–Ni–Ti system. The result presented will be helpful in phase composition analysis and in composition design of related systems.
Suicide: A Study of the Tafsīr
Authors: Silkaitis Emily 
Published: April 2022

Abstract
This article examines the tafsīr on the Qurʾānic verses pertaining to suicide, qatl al-nafs. The majority of exegetical discussions on suicide center on Moses and originate from his command to the Banū Isrāʾīl in Q 2:54, uqtulū anfusakum, which can be interpreted as “kill yourselves” or “kill one another.” On the basis of etymology and historical context, commentators associate this passage with Q 4:29 and 4:66. Another such passage, Q 2:84, which outlaws bloodshed, is also associated with the Banū Isrāʾīl, in a different context. Adding Q 18:6 and Q 2:195 to the list of verses under consideration, this article traces interpretations of self-destruction from early works of tafsīr down to the late fourteenth century. Though the Qurʾānic attitude toward suicide is notoriously ambiguous, by examining the various grammatical constructions and interpretations given to these verses, one is able to establish trends and motivations in exegesis. The discussions of suicide, and condemnations where appropriate, focus on the motivation and intention of the individual rather than the act itself. Obedience to God, the nature of his commands, and the well-being of the community of believers also emerge as some of the key ethical issues in the commentaries.
Aljamiado-Literatur als Kontaktphänomen. Die Coplas del Alhichante de Puey Monzón im literaturhistorischen Kontext
Authors: Fischer Jens G. 
Published: April 2022

Abstract
In much of the existing research concerning Aljamiado literature, we can observe attempts to assign individual texts or even the whole corpus unequivocally to a Spanish or Arabic/Islamic tradition. However, these attempts fail to adequately address the specificities of these texts and sometimes actively obscure important connections. This can be shown through an analysis of the Coplas del Alhichante de Puey Monzón, a pilgrimage narrative in verse from the sixteenth century that has so far mostly been seen as a continuation of the Arabic riḥla. This paper provides an overview of the history, past research and editions, and poetical form of the text, as well as a proposed date for its production, followed by a detailed analysis concerning its possible function which serves as a basis for comparing it to pilgrimage narratives from the Arabic/Islamic tradition and its Spanish/Christian counterparts. Contrary to what is usually assumed, the Coplas have more in common with the latter than with Arabic riḥla texts. They can therefore be interpreted as a product of a cultural “contact zone” as defined by Mary Louise Pratt. Rather than merely trying to preserve their Islamic heritage and passively receiving Christian influence, Mudéjares and Moriscos actively participated in contemporary developments in Spanish literature and used them for their own ends.

Published: April 2022

Zusammenfassung
In einem 2020 durchgeführten Kooperationsprojekt zwischen der Humboldt-Universität zu Berlin und dem Deutschen Zentrum für Hochschul- und Wissenschaftsforschung (DZWH) ist eine Forschungsfeldklassifikation entstanden, die problembezogene und interdisziplinäre Forschung in Deutschland abbildet. Ziel dieser Klassifikation ist es, Forschungsberichterstattung basierend auf disziplinorientierten Fächersystematiken innerhalb des Kerndatensatz Forschung sinnvoll zu ergänzen und somit der einem ständigen Wandel unterliegenden Forschung Rechnung zu tragen. Die Klassifikation ist in einem intellektuellen Prozess mittels Card-Sorting entstanden und hat vorhandene Forschungsklassifikationen, Forschungsfeldlisten und aktuelle Forschungsprojekte als Grundlage herangezogen. Die umfassende Einbeziehung von Stakeholdern bei der Entwicklung der Klassifikation soll deren Akzeptanz steigern und einen vielfältigen Einsatz ermöglichen.
The epithet Τιαμου of the Moon-god in Lydia
Authors: Pisaniello Valerio 
Published: April 2022

Abstract
This article discusses the origin of the epithet Τιαμου, which modifies the name of the Moon-god in a number of Greek inscriptions from Lydia dated to the 2nd-3rd century AD. All the etymological explanations provided so far will be taken into account, especially the Anatolian one, which, based on the existence of a Moon-god (κατα)χθόνιος, tries to establish a connection between Τιαμου and an Anatolian outcome of the PIE root for ‘earth’ (cf. Hitt. tēkan, Luw. tiyamm(i)-). After having discussed the arguments in favour and against both a Lydian and a Luwian origin, it will be argued that the latter seems to be most likely, although the possibility of a Lydian mediation remains.
Bilayer growth kinetics and tribological characterization of boronized AISI M2 steel
Authors: Ortiz Domínguez Martín , Keddam Mourad , Gómez Vargas Oscar Armando , Ares de Parga Gonzalo , Zuno Silva Jorge 
Published: April 2022

Abstract
The AISI M2 steel has been treated by solid boriding between 1123 and 1273 K for an exposure time of 2–8 h. In these circumstances, a bilayer constituted by FeB and Fe2B has been formed with interfaces nearly flat. The tribological behavior and decohesion resistance of boride coatings were studied by using the following characterizations: (Rockwell-C cohesion, pin-on-disc and wear scratch tests). The modeling of process kinetics was undertaken based on two different approaches (the mass balance equations and the integral method). The assessed values of boron activation energies in FeB and Fe2B arising from the two models were nearly similar. In addition, the predicted layers’ thicknesses at 1243 and 1273 K during 10 h were concordant with the experimental values.
Effects of domestication and temperature on the growth and survival of the giant freshwater prawn (Macrobrachium rosenbergii) postlarvae

Published: April 2022

AbstractTo understand the growth and survival during the postlarval stage ofMacrobrachium rosenbergii, commonly known as the giant freshwater prawn, two experiments were performed which explored the differences in growth and survival rates between wild and captive postlarvae and the effect of temperature on survival and growth. The postlarvae reared at 27 and 30°C grew significantly throughout the experimental periods. The survival rates in the wild and captive postlarvae were similar at approximately 60%. The highest survival rate of 58% was found at 27°C.

Abstract
The layer B is one of the lower layers of the long stratigraphic sequence of the Kamyana Mohyla 1 site. The layer B received eight new AMS radiocarbon dates that clarified its chronology: 7950–7300 calibrated years BC. They are in a reasonable correspondence with the dates for lower and upper layers. The lithic assemblage belongs to Kukrek cultural aspect. It is characterized by pencil-like conical cores, Kukrek inserts, Kukrek burins and Dęby burins, nongeometric microliths (oblique points). The assemblage finds close parallels in the sites of Kukrek, Ihren VIII, Melnychna Krucha SU4 and Domchi-Kaia. They can be united into Kukrek sensu stricto cultural unit. The overlying layer C yielded somewhat different complex that finds parallels in the materials of the so-called “Kukrek cultural tradition.” Due to clear stratigraphic position of these units in the Kamyana Mohyla 1 sequence, we are able to differentiate Kukrek sensu stricto and “Kukrek cultural tradition” and suggest their respective chronological positions.
