A New Transport Distance and Its Associated Ricci Curvature of Hypergraphs
Authors: Akamatsu Tomoya 
Published: June 2022

Abstract
The coarse Ricci curvature of graphs introduced by Ollivier as well as its modification by Lin–Lu– Yau have been studied from various aspects. In this paper, we propose a new transport distance appropriate for hypergraphs and study a generalization of Lin–Lu–Yau type curvature of hypergraphs. As an application, we derive a Bonnet–Myers type estimate for hypergraphs under a lower Ricci curvature bound associated with our transport distance. We remark that our transport distance is new even for graphs and worthy of further study.

Published: June 2022

Abstract
Thallium-activated sodium iodide (NaI(Tl)) detectors can be used in gamma cameras, environmental radiation assessments, including radiation emission levels from nuclear reactors, and radiation analysis equipment. This three-phase investigation aimed to model a standard NaI(Tl) detector using the Monte Carlo N-Particle eXtended (MCNPX) general-purpose Monte Carlo simulation techniques. Accordingly, a standard NaI(Tl) detector was designed along with the required properties. Next a validation study of the modelled NaI(Tl) detector has been performed based on the experimental results for absolute detector efficiency values obtained from 226Ra, 232Th, and 40K radioisotopes. Our findings indicate that the obtained absolute detector efficiency values are quite close to used experimental values. Finally, we used the modelled detector for determination of mass attenuation coefficients of Ordinary concrete, Lead, Hematite-serpentine concrete, and Steel-scrap concrete at 186.1, 295.22, 351.93, 609.31, 1120.29, 1764.49, 238.63, 911.2, 2614, and 1460.83 keV gamma-ray energies. Additionally, according to our findings, mass attenuation coefficients obtained from the newly designed detector are compatible with the standard NIST (XCOM) data. To conclude, continuous optimisation procedures are strongly suggested for sophisticated Monte Carlo simulations in order to maintain a high degree of simulation reliability. As a result, it can be concluded that the validation of the simulation model is necessary using measured data. Finally, it can also be concluded that the validated detector models are effective instruments for obtaining basic gamma-ray shielding parameters such as mass attenuation coefficients.

Published: June 2022

Abstract
Plastic gear applications are rapidly increasing in transmission systems in automotive, domestic and kitchen machineries. Biopolymer gears are now being preferred over polymer gears due to its biodegradable properties. Hence, a comparative investigation of wear characteristics between polymer and biopolymer gears is studied. Injection molded biopolymer, PLA (polylactic acid) gear and polymer, ABS (acrylonitrile butadiene styrene) gear have been fabricated with appropriate properties. Gears are experimentally tested for the period of 3 h at three different rotational speeds (500, 1000 & 1500 rpm) with and without load (1 kg). Wear debris, material loss, thermal damage and microstructure surface condition monitoring have been investigated. PLA presents better adhesive wear resistance and shows thermal deformation and tooth breakage. Biopolymer gives better thermal and wear resistance than polymer gear. At low rotational speed of 500 rpm under no-loading condition, both PLA and ABS show higher weight loss and wear rate due to thermal damage occurred due to gear pump effect. Whereas when load is applied, PLA shows wear loss at all rotational speeds due to inferior thermal conductivity and ABS shows wear loss at high rotational speeds of 1000 rpm or 1500 rpm due to loading effect.
“Jerusalem and Athens” in America: On the Biographical Background of Leo Strauss’s Four Eponymous Lectures from 1946, 1950, and 1967, And an Abandoned Book Project from 1956/1957
Authors: Kerber Hannes 
Published: June 2022

Abstract
Throughout his life, Leo Strauss (1899–1973) employed the expression “Jerusalem and Athens” to refer metaphorically to the two opposing poles of his thinking: biblical faith and ancient philosophy. While Strauss continuously stressed that “Jerusalem” and “Athens” pose a radical alternative, which demands a binary choice, he himself did not present his decision to the public. The following essay examines for the first time four different lectures that Strauss gave in New York City (1946 and 1967), Annapolis (1946), and Chicago (1950) under the title “Jerusalem and Athens.” Using not only the new first edition of the 1950 lecture published in this volume – Strauss’s most extensive public treatment of the issue – but also dozens of recently discovered archival sources, I try to illuminate the historical settings in which Strauss spoke about the tension between “Jerusalem” and “Athens.” This biographical approach highlights rhetorical strategies adopted by Strauss in his lectures and intends to show different reasons he had to abstain from opting publicly for either “Jerusalem” or “Athens.” In the concluding part, I discuss Strauss’s previously unknown but well-advanced (if eventually abandoned) plans to publish a monograph entitled Jerusalem and Athens with the University of Michigan Press in 1956/1957.
Leo Strauss’s “Jerusalem and Athens” (1950): Three Lectures Delivered at Hillel House, Chicago
Authors: Denker Laurenz , Kerber Hannes , Kretz David 
Published: June 2022

Abstract
For the first time, this edition presents Leo Strauss’s Hillel House lecture series on “Jerusalem and Athens.” The three lectures, delivered in the fall of 1950, investigate the agreement, disagreement, and conflict between the biblical and the philosophic “ways of life”: “Philosophy in the full sense is [...] incompatible with the biblical way of life. Philosophy and the Bible are the alternatives or the antagonists in the drama of the human soul. Each of the two antagonists claims to know the truth, namely, the decisive truths, the truths regarding the right way of life. But there can be only one truth, and, hence, conflict is inevitable.”
Efferent Activity Controls Hair Cell Response to Mechanical Overstimulation
Authors: Lin Chia-Hsi Jessica , Bozovic Dolores 
Published: June 2022

AbstractThe efferent pathway strengthens the auditory system for optimal performance by fine-tuning the response and protecting the inner ear from noise-induced damage. Although it has been well documented that efference helps defend against hair cell and synaptic extinction, the mechanisms of its otoprotective role have still not been established. Specifically, the effect of efference on an individual hair cell’s recovery from mechanical overstimulation has not been demonstrated. In the current work, we explored the impact of efferent stimulation on this recovery usingin vitropreparations of hair cells situated in the sacculi of American bullfrogs (Rana catesbeiana). In the absence of efferent stimulus, exposure of a hair bundle to high-amplitude mechanical deflection detuned it from its oscillatory regime, with the extent of detuning dependent on the applied signal. Efferent actuation concomitant with the hair bundle’s relaxation from a high-amplitude deflection notably changed the recovery profile and often entirely eliminated the transition to quiescence. Our findings indicate that the efferent system acts as a control mechanism that determines the dynamic regime in which the hair cell is poised.

Published: June 2022

Objective
Since the outbreak of the COVID-19 pandemic, several cases of pituitary apoplexy (PA) following a SARS-CoV-2 infection have been described in several countries. Here, we describe a case series of PA occurring in the aftermath of a SARS-CoV-2 infection to alert physicians about possible neuro-endocrinological damage caused by the virus that can lead to visual sequelae and hypopituitarism.

Design and methods
We retrospectively identified all the adult patients treated at Amiens University Hospital between March 2020 and May 2021 for PA confirmed by cerebral imaging and following an RT-PCR-confirmed SARS-CoV-2 infection.

Results
Eight cases (six women, two men) occurred between March 2020 and May 2021 and were reviewed in this study. The mean age at diagnosis was 67.5 ± 9.8 years. Only one patient had a ‘known’ non-functional pituitary macroadenoma. The most common symptom of PA was a sudden headache. Brain imaging was typical in all cases. Only two patients required decompression surgery, whereas the others were managed conservatively. The clinical outcome was favorable for all patients but without recovery of their pituitary deficiencies. There was no diabetes insipidus.

Conclusion
This case series, the largest in the literature, reinforces the strength, consistency, and coherence of the association between SARS-CoV-2 infection and PA. Our study provides support for the hypothesis that SARS-CoV-2 may be a new precipitating factor for PA. It is essential that practitioners be alerted about possible pituitary disease due to the virus so that such patients are recognized and appropriately managed, hence improving their prognosis.

Orientasi kerja mereka dipengaruhi oleh faktor penghambat, yakni sedikitnya lapangan perkerjaan yang tersedia dikarenakan sulitnya sistem rekruitmen pekerjaan di Thailand, dan faktor pendorong yakni motivasi, ekonomi, dan sumber daya manusia.
Ortaçağ Dilenci Keşiş ve Gezginci Derviş Topluluklarının Karşılaştırmalı Bir İncelemesi
Authors: ŞEN M. Seyyit 
Published: June 2022

XII. asrın sonu ve XIII. asrın geneli itibariyle Avrupa’dan Hindistan’a kadar olan
coğrafyada dini ve sosyal hayatta önemli değişimler meydana gelmiştir. Resmi dini
otoriteler dışında keşiş ve dervişlerden oluşan topluluklar zuhur etmiş ve Ortaçağ dini
hayatında önemli bir konuma yükselmişlerdir. Genel olarak tarihçiler bu tarz dini hareketleri
yerel tarzda ele almışlardır. Örneğin, Ortaçağ Avrupa tarihçileri sadece Katolik
dünyasındaki dilenci keşiş gruplarına odaklanırken, Ortaçağ İslam tarihçileri de çeşitli
derviş toplulukları üzerinde durmuşlardır. Fakat Ortaçağ’da yaşanan dinsel dönüşüm
daha genel bir perspektifle ve karşılaştırmalı bir şekilde incelemeyi gerektirmektedir. Dolayısıyla
bu makalede Ortaçağ Avrupası’ndaki dilenci keşiş hareketleri ile İslam dünyasındaki
gezginci derviş grupları karşılaştırmalı bir şekilde ele alınacak ve benzer yönleri
vurgulanacaktır. Böylelikle yerel dinamiklerden ve dini sınırlardan ziyade Ortaçağ’da
farklı coğrafyalarda benzer dini gelişmeler yaşandığı üzerinde durulacaktır.
