Erozja polskiego wybrzeża wydmowego przez spiętrzenia sztormowe w sezonie 2018/19, w tym spiętrzenie Zeetje
Authors: Łabuz Tomasz A. 
Published: April 2024

This paper presents the rate of dune erosion on the Polish Baltic coast by storm surge Zeetje in January 2019. The results were based on field measurements on coast profiles located on dune sections of the Polish coast. Presented are the hydro-meteorological parameters of all storm surges that formed before Zeetje since Autumn 2018. The hydro-meteorological parameters of storm surges that occurred during this period were analised. The amount of dune retreat after selected surges was calculated. Following smaller storm surges in the fall of 2018, dune erosion was observed in erosional sections, where beaches are usually narrower and lower. The greatest erosion of the dunes was observed after the Zeetje storm, on average up to 3 m and a maximum of 10–12 m. The average and maximum erosion of the dunes varied on individual sandbars. The average dune erosion depended on the height of water inflow onto the shore during a storm and the height of the beach. Greater erosion occurred in sections with beach heights lower than the inflow of water during the storm. The average erosion of dunes at sea level above 1.3 m was 2.5–4.0 m. The maximum erosion values were observed on the western shores of the headlands located on the central and eastern coast. Dune erosion was not observed in places where the beach height exceeded 2.5 m above sea level and was higher than the maximum water inflow during storm Zeetje.
Time characteristics of aero-optical imaging degeneration of the ellipsoidal dome under variable operating conditions
Authors: Yu Jiaqian , Zhu Chonghui , Song Wenlong 
Published: April 2024

As a missile flies at high speed, the index and surface shape of the conformal dome will vary under the influence of the aero-optical effect, which will degenerate the performance of the seeker’s imaging detection system. However, many previous studies on aero-optical imaging deterioration of optical domes were usually carried out under fixed operating conditions, which are not in line with the real flight scene of the missile. In addition, the aero-optical imaging degeneration of the dome is diverse as the flight time increases. Therefore, it is of great significance to study the time characteristics of aero-optical imaging degradation of optical domes under variable work conditions. In this study, taking an air-to-air missile as an example, the Zernike polynomials, wavefront aberration, Strehl ratio, and image simulation are applied to evaluate the aero-optical imaging deterioration of an ellipsoidal dome in the flight time range of 0–10 s under variable working conditions. The simulation results show that, as the flight time increases, (1) the dynamic range of tilt, defocus, astigmatism, coma, and wavefront aberration increase; and (2) the Strehl ratio and the peak signal-to-noise ratio (PSNR) of the simulated images decrease. Therefore, the influence of flight time on the aero-optical image degradation of the ellipsoidal dome gradually becomes more serious.
Ball-Valve Syndrome Secondary to Large Fundic Adenoma

Published: April 2024

ABSTRACT
Gastroduodenal intussusception is a rare presentation in adults. A mass lesion in the stomach typically acts as a lead point that invaginates into the pylorus and duodenum causing intussusception. In a subset of these cases, episodic symptoms of obstruction occur because of intermittent prolapse of the lesion, termed “ball-valve syndrome.” We present a 73-year-old woman with intermittent abdominal pain and nausea who was discovered to have gastroduodenal intussusception secondary to a large prolapsing fundic adenoma through the pylorus and into the duodenum. The case highlights this rare complication from gastric lesions along with the importance of surgical intervention for definitive management.
Avaliação baseada em tarefas
Authors: Morais Ana Lúcia Ferreira de , Borges-Almeida Vanessa 
Published: April 2024

Este artigo tem o objetivo de discutir características da avaliação baseada em tarefas em contextos de aprendizagem de língua estrangeira para identificar necessidades de letramento em avaliação de professores. O trabalho relata os resultados de uma investigação conduzida num centro de línguas público que recentemente havia adotado a metodologia de avaliação por tarefas. Fundamenta-se na literatura sobre ensino de línguas baseado em tarefas (Willis; Willis, 2007; Ellis, 2000; Janowska, 2014), avaliação de desempenho (McNamara, 1996; Coombe, 2018) e avaliação para/como aprendizagem (Black et al., 2003; Brookhart, 2013; Carless, 2007; Coombe; Folse; Hubley, 2007; Earl, 2013). Participaram da pesquisa três professoras que lecionavam diferentes níveis de proficiência na escola. Os dados foram coletados por meio de observações de aulas, notas de campo, entrevistas e análise documental. Todos os instrumentos avaliativos utilizados pelas participantes foram analisados quanto a suas características, e os procedimentos empregados foram observados durante a totalidade das aulas lecionadas no período de um semestre letivo. Os resultados indicam o emprego de poucas tarefas de fato, escassez de autenticidade, e oferta de feedback essencialmente corretivo. Em decorrência disso, permitem apontar a necessidade de investimento no letramento em avaliação de professores de línguas para que possam refinar seus conhecimentos sobre tarefas e aprimorar suas práticas avaliativas, de modo a desenvolverem práticas, não apenas mais válidas e confiáveis, como também com maior potencial para orientar a aprendizagem.

Abstract
We prove that the Bergman kernel function associated to a smooth measure supported on a piecewise-smooth maximally totally real submanifold 𝐾 in

C
n

\mathbb{C}^{n}

is of polynomial growth.
For example, this holds in dimension one if 𝐾 is a finite union of transverse Jordan arcs in ℂ.
Our bounds are sharp when 𝐾 is smooth.
We give an application to the equidistribution of the zeros of random polynomials, which extends a result of Shiffman–Zelditch to the higher-dimensional setting.
A Third Directive on Consumer Credit
Authors: Arroyo Amayuelas Esther 
Published: April 2024

Abstract
The recently adopted Consumer Credit Directive incorporates new forms of credit and uses classic consumer protection instruments as well as introducing measures that increase control over lenders with the aim of preventing over-indebtedness. In general, more burdens are imposed on lenders and certain commercial practices are banned or restricted in all Member States. Moreover, the Directive is characterised by the fact that it includes consumer data protection and specifies a consumers’ right not to be discriminated against, which may have some overlap with the General Data Protection Regulation and the on-going development of EU artificial intelligence legislation.
The Unfairness of Personalised Price Terms in Consumer Credit Products
Authors: Tjon Akon Melvin 
Published: April 2024

Abstract
This article examines whether, and if so to what extent, a lender can engage in the algorithmic personalised pricing of consumer credit products (PP) under the Unfair Contract Terms Directive (UCTD) and the Consumer Credit Directive (CCD). To this end, the author first analyses the economic literature to discuss the mechanics of PP and the economic impacts on different consumer groups. This overview is followed by an examination of the UCTD and the CCD, in the broader context of EU regulatory law, as these Directives apply to the practice and the contractual terms. Subsequently, the author applies the considerations of the European Court of Justice (CJEU) in the jurisprudence regarding price terms in credit and mortgage agreements to personalised price terms. Finally, the author concludes that the Directives indeed limit the extent to which a lender can engage in PP, but that the frameworks in the broader EU regulatory context would be better suited than the Directives to address the negative economic impacts of the practice.
Explaining the Divergence in German and French Public Finances
Authors: Eisl Andreas 
Published: April 2024

Abstract
In this contribution, I discuss the divergence of German and French public finances over the course of the last two decades. Major gaps in public deficit/debt levels and debt service costs have opened even under the presence of a common fiscal framework at the EU level. To explain these differences, I focus on three elements: the (non-)perception of budgetary and socio-economic crisis, differences in demographic conditions, and contrasting approaches towards the role of rules and expertise in fiscal policymaking. The contribution illustrates these points by providing two concise case studies on key developments in fiscal policymaking and institutions since the 1990s. I conclude with a brief reflection on German and French fiscal policymaking in the years to come.
‘My dearest Clara … my dear friend’ – Personal Names and direct address in Mary Hamilton’s private correspondence
Authors: Yáñez-Bouza Nuria 
Published: April 2024

Abstract
In the eighteenth century, a period dominated by linguistic correctness, propriety and etiquette, appropriate forms of address are a customary feature in correspondence and a key means by which individuals are able to construct their social identity in light of their relationships with others. In this context, and framed within the fields of historical sociolinguistics and historical sociopragmatics, this paper explores the role of direct address as a socially-governed linguistic practice and as an index of politeness, and the focus lies in intra-speaker variation in the use of personal names and honorifics in the opening, body and subscription parts of the letter. The study is based on a set of 170 private letters written by Mary Hamilton (1756–1816), courtier, diarist and a member of the Bluestocking circle, and the analysis considers notions traditionally connected with pragmatic language use such as distance, power and politeness, bearing in mind other content-dependent factors as well. Overall, the research presented here aims to contribute to a growing body of literature which understands ego-documents as providing a window onto language and society.
Adverse reactions of piperacillin: A literature review of case reports
Authors: Zhang Hongru , Yang Liping 
Published: April 2024

AbstractAimThis study aimed to summarize case reports of adverse drug reactions (ADRs) caused by piperacillin and explore their effects on human organs in real-world settings.MethodCase reports of piperacillin ADRs were collected by searching databases such as PubMed, Embase, Web of Science, CNKI, WanFang, and VIP from inception to December 2022.ResultsA total of 170 patients were ultimately included. The results revealed that ADRs caused by piperacillin were primarily associated with the entire body, followed by the blood system, skin and soft tissues, and the nervous system. The most frequently reported cases included anaphylactic shock, drug fever, rash, and thrombocytopenia. The most severe ADRs were identified as anaphylactic shock and bullous epidermal necrolysis. Furthermore, a comparison was made between systemic adverse reactions caused by piperacillin as a single drug and two composite preparations of piperacillin/β-lactamase inhibitor. ADRs not mentioned in the instructions included convulsions or hallucinations and Kounis syndrome (KS).ConclusionThis review suggests that the most severe ADRs associated with piperacillin are toxic epidermal necrolysis and anaphylactic shock. Rare ADRs caused by piperacillin, such as myoclonic jerks, hallucinations, and KS, were identified. The most common symptom with domestic preparations of piperacillin/sulbactam and piperacillin sodium was dyspnea.

Abstract

Objectives
The 2bRAD sequencing for Microbiome (2bRAD-M) represents an innovative and streamlined approach for the reconstruction of microbial profiles at the species level. In our investigation, we conducted 2bRAD-M analysis to characterize the microbiome of bladder tissue in patients with muscle-invasive bladder cancer (MIBC).

Methods
15 tumor tissues and 15 paired para-carcinoma tissues were obtained from the bladder excised during surgery. 2bRAD-M sequencing was used to assess the abundance of microorganisms in samples.

Results
The microbial community structure and biodiversity, as assessed at varying taxonomic ranks, exhibited a high degree of similarity between the tumor and paired non-tumor tissues. At the genus level, we observed a notably elevated abundance of Brachybacterium and Haloparvum, coupled with a diminished abundance of Anoxybacillus, Anoxybacillu_A, Deinococcus, NCEH01, and Pseudoxanthomonas_A in the tumor tissues. Meanwhile, at the species level, the non-tumor tissues exhibited an enrichment of Anoxybacillus_A rupiensis, Anoxybacillus flavithermus_G, Klebsiella quasipneumoniae, NCEH01 sp002304505, and Pseudoxanthomonas_A sp004284195. Linear discriminant analysis effect size (LEfSe) identified 29 discriminative features, characterized by significant variations (p<0.5, LDA≥2.0) in relative abundance between the two groups. Furthermore, an analysis of functional predictions utilizing Phylogenetic Investigation of Communities by Reconstruction of Unobserved States 2 (PICRUSt2) also uncovered disparities in the microbial functional composition.

Conclusions
This study identified several microorganisms that exhibit differences between MIBC tumor tissue and adjacent non-tumor tissue using 2bRAD-M sequencing, providing some insights into the potential association between the bladder microbiome and cancer.
A two-stage framework for predicting the remaining useful life of bearings
Authors: Zhan Xianbiao , Liu Zixuan , Yan Hao , Wu Zhenghao , Guo Chiming , Jia Xisheng 
Published: April 2024

Abstract
The traditional prediction of remaining useful life (RUL) for bearings cannot be calculated in parallel and requires manual feature extraction and artificial label construction. Therefore, this article proposes a two-stage framework for predicting the RUL of bearings. In the first stage, an unsupervised approach using a temporal convolutional network (TCN) is employed to construct a health indicator (HI). This helps reduce human interference and the reliance on expert knowledge. In the second stage, a prediction framework based on a convolutional neural network (CNN)–transformer is developed to address the limitations of traditional neural networks, specifically their inability to perform parallel calculations and their low prediction accuracy. The life prediction framework primarily maps the complete life data of bearings onto the HI vector. Based on the HI constructed through TCN, the known HI is input into the CNN–transformer network, which sequentially predicts the remaining unknown HI. Finally, the effectiveness and superiority of the proposed method are verified using two bearing datasets, providing validation of its capabilities.
Reflections in time: Migration Period mirror recently found east of the Carpathians

Published: April 2024

Zusammenfassung
In dieser Studie wird ein „östlicher“ Spiegel mit zentraler Schleife untersucht, der mit dem Typ Berjozovka-Carnuntum-Mödling verwandt ist und kürzlich in Secuieni, Kreis Bacău, Rumänien, entdeckt wurde. Diese Spiegel sind bei Nomadenstämmen verbreitet. Sie wurden vor allem im nördlichen Kaukasus sowie nördlich und nordwestlich des Schwarzen Meeres gefunden. Die Spiegel kamen während der Völkerwanderung nach Europa und begleiteten die Alanen und die hunnischen Stämme nach Osten. Im 5. Jh. n. Chr. wurden sie vor allem im mittleren und unteren Donauraum gefunden. Die meisten Spiegel stammen aus Frauengräbern, oft mit künstlich deformierten Schädeln, die mit Prestigegegenständen (wie großen Silberfibeln mit halbkreisförmigen Kopfplatten, Adlerfibeln, Golddiademen, granulierten Ohrringen, Perlen usw.) bestattet wurden. In Rumänien sind nur zwölf solcher Spiegel dokumentiert, und in der Region Moldau (Rumänien, Region zwischen Ostkarpaten und Pruth) nur einer in fragmentarischer Form. Der neu entdeckte Spiegel von Secuieni ist daher von großem archäologischen Wert und wirft ein Licht auf die archäologische Landschaft der Völkerwanderungszeit östlich der Karpaten und weit darüber hinaus, bis nach China.
Effect of Static Stretching on Tendon Hysteresis and Efficiency During Repetitive Jumping

Published: April 2024

Abstract
Sasajima, S and Kubo, K. Effect of static stretching on tendon hysteresis and efficiency during repetitive jumping. J Strength Cond Res 38(6): 1041–1047, 2024—To date, no studies have experimentally shown a relationship between tendon hysteresis and exercise efficiency. However, previous studies showed that tendon hysteresis decreased immediately after static stretching. The purposes of this study were to (a) investigate the change in tendon hysteresis during the recovery period after static stretching and (b) determine whether exercise efficiency is enhanced because of the decline of tendon hysteresis after static stretching. For stretching (1 minute × 4 sets) and control conditions, tendon hysteresis was measured during ramp (i.e., lower strain rate of tendon) and ballistic (i.e., higher strain rate of tendon) contractions before, immediately, 15, 30, 45, and 60 minutes after interventions. In addition, electromyograms of the plantar flexor muscles (medial gastrocnemius [MG], lateral gastrocnemius [LG], and soleus muscles [SOL]) and oxygen consumption (V̇O2) were measured during 10 minutes of submaximal repetitive jumping after both interventions. Tendon hysteresis (during ramp and ballistic contractions) reduced by static stretching persisted for up to 60 minutes (effect of time p < 0.001). During repetitive jumping, no differences in electromyograms of the plantar flexor muscles (effect of condition p = 0.786 for MG, p = 0.124 for LG, p = 0.682 for SOL) or V̇O2 (effect of condition p = 0.534) were found between stretching and control conditions. These results suggest that the reduction in tendon hysteresis because of static stretching continues until 60 minutes after the end of stretching, and static stretching does not change the efficiency (evaluated by electromyograms of the plantar flexor muscles and V̇O2) during submaximal repetitive jumping.

Abstract
Hickmott, LM, Butcher, SJ, and Chilibeck, PD. A comparison of subjective estimations and objective velocities at quantifying proximity to failure for the bench press in resistance-trained men and women. J Strength Cond Res 38(7): 1206–1212, 2024—The purpose of this study was to compare the accuracy of quantifying repetitions in reserve (RIR) in the bench press among 18 men and 18 women between 2 conditions: (a) subjective estimations and (b) objective velocities. Subjects performed 4 sessions over 10 days: (a) 1 repetition maximum (1RM) test; (b) repetition-to-failure test at 80% of 1RM; (c) 3 sets to failure at 80% of 1RM; and (d) 3 sets to failure at 75, 80, and 85% of 1RM. During sessions 2, 3, and 4, subjects verbally stated their perceived 4 and 2 RIR intraset, whereas average concentric velocity was recorded on all repetitions. The dependent variable for the subjective estimations condition was the difference between the actual number of RIR and the subject’s subjective estimated number of RIR at the verbally stated 4 and 2 RIR. The dependent variable for the objective velocities condition was the difference between the actual number of RIR and the number of RIR calculated from the subject’s baseline individualized last repetition average concentric velocity-RIR profile. Significance was set at p ≤ 0.05. Sessions 3 and 4 had significant (p < 0.001) condition × set and condition × load interactions, respectively, at both 4 and 2 RIR. Objective velocities were significantly more accurate than subjective estimations on set 1 and set 2 at both RIRs during session 3 and for 75 and 80% of 1RM at both RIRs during session 4. Objective velocities exhibit significantly greater accuracy than subjective estimations at quantifying RIR during initial sets and lower loads.
