On the Possibility of Rapid Changes in Ocean Circulation in the Atlantic Segment of the Global Circulation Conveyor: Model Experiment
Authors: Ivanov Vladimir V. , Gusev Anatoly V. , Diansky Nikolay A. , Sukhonos Pavel A. 
Published: October 2023

Abstract

In this model study, we address the feasibility of rapid shutdown or, at least, substantial weakening of the Global Circulation Conveyor (GCC) caused by massive discharge of freshwater to the northern North Atlantic (NA). The source of this freshwater excess is the permanently ice-covered Arctic Ocean (AO), while its release may be caused by ice melting and intensified river runoff due to global warming. To check up the validity of this hypothesis, we carried out the two idealized experiments with opposite atmospheric forcings over the AO: the so-called "cyclonic" one, which favors intensive water exchange between the AO deep interior and the Nordic Seas (NS), and "anticyclonic" one, which impedes this exchange. We chose the two actual years with extremal forcings (1989 as cyclonic one, and 2004 as anticyclonic one) and artificially applied these forcings during the 10-year period assuming that such a duration is at the margin of physical realism. Our major finding, within the limitations of numerical experiments on the OGCM (Ocean General Circulation Model) INMOM (Institute of Numerical Mathematics Ocean Model), shows that anomalously long preservation of "cyclonic" forcing over the AO is able to substantially rearrange salinity in the upper ocean layer. However, it may not trigger massive "instant" outflow of freshwater through the Fram and Denmark Straits, since a large portion of accumulated in the Beaufort Gyre freshwater spreads around the AO following the circulation without reaching the Fram Strait. However, the tendency of the upper ocean layer freshening in the northern NA due to flushing of freshwater from the AO is confirmed in consistency with the basic concept of the GCC hiatus.

Abstract

Objectives
This study aimed to estimate the incidence rate of re-fracture and all-cause mortality rate in patients with hip fractures caused by minor trauma in the first year following the event.
Materials and Methods
This is a retrospective cohort study of patients over 50 years of age conducted in a referral hospital located in Tehran (Shafa-Yahyaian). Using the hospital information system (HIS), all patients hospitalized due to hip fractures caused by minor trauma during 2013–2019 were included in the study. We investigated the occurrence of death and re-fracture in all patients one year after the primary hip fracture.
Results
A total of 945 patients with hip fractures during a 307595 person-days of follow-up, were included. The mean age of the participants was 71 years (SD = 11.19), and 533 (59%) of them were women. One hundred forty-nine deaths were identified during the first year after hip fracture, resulting in a one-year mortality rate of 17.69% (95% CI: 15.06–20.77). The one-year mortality rate was 20.06% in men and 15.88% in women. Out of all the participants, 667 answered the phone call, of which 29 cases had experienced a re-fracture in the first year (incidence rate = 5.03%, 95% CI: 3.50–7.24). The incidence rates in women and men were 6.07% and 3.65%, respectively.
Conclusion
Patients with low-trauma hip fractures have shown a high rate of mortality in the first year. Considering the increase in the incidence of hip fractures with age, comprehensive strategies are needed to prevent fractures caused by minor trauma in the elderly population.
Catecholase Activity Assessment of In-Situ Copper Complexes Derived from a Novel Schiff Base Ligand
Authors: Belfilali I. , Roisnel T. 
Published: October 2023

Abstract

This study focuses on the synthesis, characterization, and evaluation of catecholase activity in a series of in-situ copper complexes derived from a novel Schiff base ligand, MBPM. The ligand MBPM and its complex [Cu(MBPM)] were successfully synthesized and characterized using various analytical techniques, including X-ray crystallography, IR spectroscopy, and 1H NMR spectroscopy. Subsequently, we investigated the catalytic activity of these complexes in the oxidation of catechol to o-quinone. The results revealed a remarkable difference in catecholase activity between the Schiff base ligand-derived complex, [Cu(MBPM)], and in-situ copper complexes. The [Cu(MBPM)] complex exhibited significantly higher catalytic activity, underscoring its potential as an efficient catalyst for catechol oxidation. This enhanced activity can be attributed to structural differences and the presence of multiple active sites within the [Cu(MBPM)] complex.
Machine learning aided investigation of dynamics of immiscible droplet impingement on liquid pools: A study across varying pool depths and droplet viscosities

Published: October 2023

Abstract
The interactions of an immiscible droplet impinging on liquid pools bear significant implications across a wide array of applications, as well as in natural phenomena. In this paper, the dynamics associated with an immiscible droplet impinging on a liquid pool/film of varying depths have been elucidated. The study encompasses the impact of silicone oil droplets of four different viscosities (1, 10, 100, and 1000 cSt) upon a water pool of three non-dimensional pool heights h* = 1, 2.5, and 5. The phenomenon of droplet impact at two Weber numbers (We = 50 and 100) is captured through high-speed videography. The dynamics of impingement, associated with the immiscible liquid combination, are delineated by employing Mask R-CNN machine learning (ML) model. ML model generated masks are used to ascertain the dynamics of various cavity parameter. Further insights into the phenomena have been developed through a detailed energy analysis carried out pre- and post-impact. The performance of ML model is compared with the manually annotated images, exhibiting impressive level of agreement. Results reveal that during the cavity formation phase, low viscosity droplets conform to the cavity shape during their descend into the pool. In contrast, high viscosity droplets maintain their shape during cavity formation, showing pinning at the oil-water interface. Energy analysis shows better energy transfer from droplet to the cavity for low viscosity droplets (> 90%), while less than 50% of the impact energy is transferred for higher viscosity droplets. This study is among the first to apply machine learning to this complex fluid phenomenon, offering insights into the physics and potential applications in multiphase flows.
An investigation of errors in ellipse-fitting for cold-atom interferometers
Authors: Ridley Kevin , Rodgers Anthony 
Published: October 2023

Abstract

Ellipse fitting is a technique which is used to extract differential phase in cold-atom interferometers, particularly in situations where common-mode noise needs to be suppressed. We use numerical simulation to investigate errors in the ellipse fitting process; specifically, errors due to the presence of additive noise, linear drift in ellipse offset and amplitude, as well as an error that can arise from fringe normalisation. Errors are found to manifest in two ways: bias in the ellipse phase measurement and incomplete suppression of common mode phase noise. We quantify these errors for three different ellipse fitting algorithms and discuss the applicability of these results to future cold atom sensors.

Published: October 2023

Abstract

Purpose The aim of this study was to analyze the relationship between the location and number of foramen nutricium (FN) on the clavicle and other clavicular parameters. Methods This study was performed on 86 dry clavicles (46 left, 40 right). Morphometric measurements were measured with a digital caliper. Results The most of the bones had a single FN. There was no FN on 3 bones, and there were 4 FN on 2 bones. The right-left side differences in the sagittal and vertical thickness of the sternal end (STs and VTs, respectively), the distance of the FN to the sternal end and the posterior edge (DFS and DFpost, respectively) and the foraminal index (FI) were statistically significant. There was a positive correlation between some FN parameters and clavicular parameters. FN was mostly located in Type 2 and was mostly located in the inferior face. The bones without FN were longer and thicker. The vertical and sagittal thickness of the thinnest point of the clavicle was greater in bones with 4 FN. Conclusion It was observed that there was a relationship between the number and location of the FN and its morphometric features, and many clavicular parameters. Knowing the location of the FN on the clavicle is important for protecting the nutrient artery in orthopedic surgery applications.
Application of mapping and statistical study for the assessment of surface water quality in the Safsaf River (North-Eastern Algeria)
Authors: Fadila FEKRACHE , BOUDEFFA  
Published: October 2023

Abstract
The Skikda region, primarily industrial and agricultural, has experienced significant accelerated industrial and agricultural development over the past decade, resulting in abundant untreated discharges into the physical environment. Our study focused on the physicochemical analysis of the water of the Safsaf River in Skikda. It is based on monitoring three stations during the months of March and August. The aim of this study was to assess the quality of this water and characterize its suitability for agricultural use. To this end, we determined the values of the following physicochemical parameters: Electrical Conductivity (EC), pH, turbidity, total alkalinity (TA), chlorides (Cl-), sodium (Na+), potassium (K+), nitrite (NO2-), ammonium (NH4+), Biological Oxygen Demand (BOD5), and phosphates (PO4-3). The results show that electrical conductivity, sodium, potassium, and chlorides increase downstream of the watershed due to seawater intrusion into the plain. As for the origins of phosphate pollution, whose concentrations have significantly increased along the river, we can explain it by pollution generated by the use of phosphate fertilizers and return irrigation water into surface waters, as well as pollution due to direct input of domestic wastewater.
Molecular Signatures of Cervical Cancer Risk in the Context of HIV Infection: Potential biomarkers of immune activation
Authors: Okoye Jude Ogechukwu 
Published: October 2023

Abstract
The disparity in cervical cancer incidence and mortality between high-income and low-income countries, exacerbated by the co-occurrence of HIV infection and cervical cancer, presents a complex and distinctive healthcare challenge. Addressing this challenge necessitates a comprehensive investigation into intricate molecular markers for predicting heightened cancer risk. This study assessed the cellular levels of cervical cancer-related specific oncomirs (miR-21, miR-146a, miR-155, miR-182, and miR-200c) and tumour suppressors (miR-let-7b, miR-125b, miR-143, miR-145, and p53) among women living with HIV (HIV+) and those without HIV (HIV-).
Methods: This case-control study was conducted from May 2017 to April 2019 in Abeokuta, Nigeria, and involved two groups: HIV+ (n = 103) and HIV- women (n = 70).
Results: The study revealed significantly higher levels of miR-155 and p53 in HIV+ women compared to their HIV- counterparts (p = 0.046 and 0.033, respectively). Conversely, significantly lower levels of miR-182, miR-200c, and miR-125b were observed in HIV+ women compared to their HIV- counterparts (p= 0.035, 0.045 and 0.004, respectively). Notably, a significant positive correlation was observed between miR-155 and miR-145 in both HIV+ and HIV- women (p < 0.05). Among HIV- women, direct relationships were also observed between miR-155 and miR-125b (p= 0.004), miR-200c and miR-125b (p= 0.033), and miR-200c and p53 (p= 0.003).
Conclusion: This study indicates that HIV upregulates p53 and miR-155, and downregulates miR-125b, miR-182, and miR-200c. This suggests that the upregulation of the tri-miRNA and downregulation of miR-155 through targeted therapy could mitigate HIV-associated immune activation thereby forestalling cervical cancer development.
Investigation secrète et nemo tenetur : l'exercice (trop?) sensible de la récolte d'aveux
Authors: Gauderon Ryan 
Published: October 2023

L'investigation secrète (art. 285a ss CPP) peut être mise en œuvre également contre une personne physique pour la poursuite d'une infraction grave. Lorsque l'agent infiltré intervient en vue d'obtenir des aveux du prévenu, le droit de ne pas s'auto-incriminer de ce dernier réduit considérablement l'étendue de l'intervention. En cas de provocation d'aveux, se pose la question des conséquences sur les déclarations ainsi obtenues. Le Tribunal fédéral a répondu à cette question dans l'ATF 148 IV 205, mais sans traiter les cas moins évidents que celui dont il a été amené à juger. La présente contribution revient sur cet arrêt de principe pour identifier les solutions qui pourraient être appliquées en cas de légère provocation, notamment sous l'angle de l'art. 293 al. 4 CPP.

Die verdeckte Ermittlung (Art. 285a ff. StPO) kann auch gegen eine einzelne Person zur Verfolgung schwerer Straftaten eingesetzt werden. Wenn der verdeckte Ermittler tätig wird, um ein Geständnis des Beschuldigten zu erwirken, schränkt dessen Recht, sich nicht selbst belasten zu müssen, den Umfang der Ermittlung erheblich ein. Wird auf diese Weise ein Geständnis provoziert, stellt sich die Frage nach dessen Verwertbarkeit. Das Bundesgericht hat sich damit in BGE 148 IV 205 beschäftigt, allerdings ohne Regeln für weniger eindeutige Fälle aufzustellen. Dieser Beitrag greift dieses Grundsatzurteil auf und zeigt insbesondere unter Berücksichtigung von Art. 293 Abs. 4 StPO Lösungen auf, die im Falle leichter Geständnis-Provokationen angewandt werden könnten.
Social Thought of Russia in the 18th Century: Notes on Research Methodology
Authors: Занин С.В. 
Published: October 2023

Рассмотрен ряд подходов к изучению общественной мысли в России времени Петра Великого и Екатерины II, развитые в современной историографии, указаны ряд источников, прежде всего переводы сочинений европейских неостоиков (Слейдан, Липсий), сочинения Екатерины II, Н.И. Панина и Д.А. Голицына, прежде не привлекавших внимания отечественных исследователей. Установлено, что в эпоху Петра Великого русская общественная мысль находилась под влиянием гетерогенных по своему характеру политических концепций Западной Европы, что создавало возможности для различных интерпретаций учений неостоиков, Пуфендорфа и о «государственном интересе». Автор статьи подчеркивает необходимость анализа переводов сочинений западноевропейских политических писателей на русский язык с точки зрения смысловой целостности перевода, дополняя его встречным изучением на современном уровне содержащихся в них концепций. На примерах собственных исследований автор показал особенности построения политического дискурса в ряде сочинений эпохи Екатерины II, указав на плодотворность изучения дискурсивных практик, создававшихся в России, в рамках которых термины, в том числе заимствованные из чужого языка или переведенные с него, получали статус понятий.
Several approaches in the current historiography to studying the social thinking in Russia of the times of Peter the Great and Catherine the Great have been observed, the series of resources have been mentioned, most notably, the translations of the works of neo-stoic authors (Sleidanus, Lipsius), the works of Catherine the Great, N.I. Panin and D.A. Gallitzin, formerly not received Russian scholars' attention. It is deemed that in the times of Peter the Great Russian social thinking was under the influence of the heterogeneous in conception West European political base, that provided an avenue for different interpretations of the works of neo-stoic authors and Samuel von Pufendorf and about "the state interest". The author of this paper highlights the necessity of the analysis of the translations of the West European political works into Russian in the context of semantic continuity of those translations, alongside with the research of the concepts contained then and at the present times. The author has presented the peculiarities of building the discourse in several papers of the times of Catherine the Great evidenced from his own researches, drawing attention to fruitful researches of the discourse practices done in Russia, within those the terms, translated or adopted from other languages, became the concepts.

The Habsburg Myth and Political Processes in Europe in the 20th and at the Beginning of the 21st cc.: The Pan-European Idea and Regional Identities
Authors: Крючков И.В. , Крючкова Н.Д. 
Published: October 2023

В представленной статье рассматривается влияние габсбургского мифа на развитие политических процессов в регионах и государствах, возникших на территории бывшей империи Габсбургов во второй половине ХХ – начале XXI вв. Распространение в регионе авторитаризма (тоталитаризма) и Вторая мировая война способствовали реабилитации империи Габсбургов в исторической памяти народов Центрально-Восточной Европы и соседних регионов и осознанию ими общности исторического, политического и культурного развития. Принадлежность к габсбургскому пространству является важнейшим политическим кодом, определяющим европейскость Центрально-Восточной Европы, ее отличие от России. В материале также показано влияние интеллектуального наследия империи Габсбургов, габсбургского мифа на формирование общеевропейской идеи, интеграционные процессы в Европе после Второй мировой войны.
This article examines the impact of the Habsburg myth on the development of political processes in regions and states that emerged on the territory of the former Habsburg Empire in the second half of the twentieth and at the beginning of the twenty-first centuries. The spread of authoritarianism (totalitarianism) in the region and the World War II contributed to the rehabilitation of the Habsburg Empire in the historical memory of the peoples of Central and Eastern Europe and neighbouring regions and to their awareness of the common historical, political and cultural development. Belonging to the Habsburg space is the most important political code that defines the Europeanness of Central and Eastern Europe, its difference from Russia. The material also shows the influence of the intellectual heritage of the Habsburg Empire and the Habsburg myth on the formation of the pan-European idea and the integration processes in Europe after the World War II.
