Authors: Aouani Hajer , Amara Sofiene 
Published: March 2024

The aim of this study was to study the effect of setting a personal goal to achieve on psychological parameters (cognitive anxiety, somatic anxiety and self-confidence) and on the chronometric performance of 50m butterfly in young swimmers. aged between 12 and 13 years old during the 2019/2020 sports season. The population was divided into three groups, the first group1 (G1) underwent competition preparation without a set goal (method1), the second group2 (G2) was oriented towards a vague goal “Do your best” (method2) , whereas, the third group was asked to respond to a difficult-to-achieve goal according to a goal-setting interval (GBI) (method3). The results indicate that method 1 and method 3 increased the level of cognitive and somatic anxiety in swimmers in these two groups (p < 0.05). Furthermore, the self-confidence score was low in group 1 compared to the other two groups. Our results also show that chronometric performance was improved (p < 0.05) better by method 3 than by method 2, while performance remained unchanged in group 1. The difficult goal setting by IFB improved the chronometric performance, but at the same time increased the values of cognitive and somatic anxiety, for this reason the mental trainers and the technical staff were invited to develop associated mental preparation models to this method of goal setting to help swimmers psychologically.

Published: March 2024

Cocoa bean has an important role in the agricultural economy of Indonesia for its foreign earnings. Demand for high quality of cocoa beans is increasing fast due to the expansion of global cocoa and chocolate market. Bali Province also plays an important role in Indonesia’s cocoa production and export where the main cocoa plantation lies in Jembrana Regency cultivated by small-scale farmers. Chocolate industry requests for high quality cocoa beans from fermented cocoa for high prices, however farmers are still reluctant to do fermentation. This study aims at analyzing probability of farmer’s decision to ferment cocoa beans at Jembrana Regency, Bali Province, Indonesia. Logit regression was utilized where the dependent variable is in binary, which is the change in probability of a cocoa producer choosing to ferment their cocoa beans, given the independent variables included farm size, production and other occupation of farmers. The result from the average marginal effect shows that only production variable is significant to increase the probability of the cocoa farmers to ferment their cocoa beans. Result from the analysis indicates that on average for one kilogram increase in cocoa production per month, the probability of observing increases fermentation by approximately 0.26 percentage point. In other words, higher production volume increases the probability of the cocoa producers to ferment their cocoa beans. It is suggested to multi stakehonders in cocoa industry to further improve production through the implementation of good agricultural practices (GAP) and extending training for cocoa farmers.
On subsolutions and concavity for fully nonlinear elliptic equations
Authors: Guan Bo 
Published: March 2024

Abstract
Subsolutions and concavity play critical roles in classical solvability, especially a priori estimates, of fully nonlinear elliptic equations. Our first primary goal in this paper is to explore the possibility to weaken the concavity condition. The second is to clarify relations between weak notions of subsolution introduced by Székelyhidi and the author, respectively, in attempt to treat equations on closed manifolds. More precisely, we show that these weak notions of subsolutions are equivalent for equations defined on convex cones of type 1 in the sense defined by Caffarelli, Nirenberg and Spruck.

Abstract
Although there has been a great deal of research on L2 writing in higher education over the past few decades, limited attention has been given to secondary students’ writing motivation and engagement in L2 writing contexts. The present study aims to examine the association between writing instructional approaches and student writing motivation and engagement in the Chinese EFL context, and investigate the mediating role of writing feedback in this relationship. 2,169 students from 35 secondary schools in mainland China participated in this study. Results showed that product-oriented teaching approach related positively to the three indicators of maladaptive motivation (i.e., anxiety, failure avoidance, and uncertain control) and process-oriented teaching approach related positively to the two indicators of adaptive engagement (i.e., task management, persistence). While genre-oriented teaching approach related positively to adaptive motivation and engagement, and related negatively to maladaptive motivation and engagement, cooperative multimedia writing teaching approach related negatively to adaptive motivation and one factor of adaptive engagement (i.e., task management), and related positively to two factors of maladaptive motivation (i.e., anxiety, failure avoidance) and maladaptive engagement. This study also identified the mediating role of four feedback practices (i.e., learning-oriented feedback, expressive feedback, computer-mediated feedback, and peer and self feedback) in the associations between writing instructional approaches and student writing motivation and engagement. This study provides insights into our understanding of the complex relationship among teachers’ instruction, classroom feedback practices, and student writing motivation and engagement in L2 school contexts.
Spiel, Minne, Schwur und Markt
Authors: Meyer Adrian 
Published: March 2024

Abstract
Hartmann von Aue’s ›Ereck‹ and ›Iwein‹, Wolfram von Eschenbach’s ›Parzival‹ and Heinrich von dem Türlin’s ›Crône‹ all include fighting scenes that link mutual physical exhaustion and elaborate metaphors to a spectrum of outcomes between winning and losing. The metaphors derive from quotidian social contexts of a courtly audience: games, love, oaths and markets connote constellations of equality or superiority. While the metaphors illuminate the hierarchy of the two fighters, I argue, they also mirror the cause of the fight on the discursive level. The scenes thus form an intertextual group featuring a poetological connection between exhaustion and the metaphorical visibility of the cause of the fight.
Evaluation of reclaimed asphalt mixtures rejuvenated with waste engine oil to resist rutting deformation

Published: March 2024

Abstract
Reclaimed asphalt pavement (RAP) is a sustainable and cost-effective way to reduce the need for virgin asphalt in road construction and rehabilitation. However, RAP is often hard and brittle, leading to performance problems. Rejuvenators can be used to restore RAP's physical and rheological properties, but many conventional rejuvenators are petroleum-based and have environmental drawbacks. The objective of this study is to assess the rutting and moisture resistance characteristics of reclaimed asphalt mixtures rejuvenated with waste engine oil (WEO), with a particular focus on regions characterized by hot climates, such as Iraq. This study investigated WEO as a rejuvenator for RAP and oxidized asphalt grade 30–40. WEO is a waste product that can be recycled and reused, making it a sustainable and environmentally friendly rejuvenator. The study found that asphalt mixes containing RAP rejuvenated with WEO had improved mechanical performance compared to conventional asphalt mixes. Marshall stability increased by up to 30%, indirect tensile strength increased by up to 29%, moisture resistance improved by up to 19%, resilience to stripping increased by up to 97%, and rutting resistance increased by up to 64.5%. The study findings suggest that asphalt mixtures containing RAP rejuvenated with WEO are a promising new technology for sustainable road construction and rehabilitation. WEO is a waste product that can be recycled, reused, and used to produce asphalt mixes with improved mechanical performance. The novelty of this study is the use of WEO as a rejuvenator for RAP. WEO is a waste product that can be regenerated and reused, making it a sustainable and environmentally friendly rejuvenator. The study also investigated the optimal WEO concentration for rejuvenating RAP asphalt mixes, which is important for producing asphalt mixes with the desired performance characteristics.

Authors: Kishor Yugal , Patel Ramnarayan , Sahu Lalit Kumar 
Published: March 2024

Abstract
A high-step-up DC–DC converter (DDC) is commonly used in micro-grids, renewable energy source (RES) integration, uninterruptible power supplies, hybrid vehicles, and other applications to deal with intermittency in power sources. Solar photovoltaic (SPV) is a prominent RES due to its many benefits, but its output voltage must be enhanced for high-voltage (HV) applications; hence, various topologies are suggested for desirable gain in the literature. Nevertheless, contemporary topologies exhibit restricted gain, higher device stress, analysis on restricted performance metrics, constrained handling capacity for input variations, relatively lower reliability, and suboptimal device utilization. This work investigates a new Z-source with switched-capacitor (HZSSC)-based hybrid step-up converter to solve the aforementioned restrictions and adapt PV voltage dynamics. Additionally, this paper presents MIL-HDBK-217F-based methodology for evaluating converter-level reliability, assessing the implications of device parametric variation on overall reliability, conducting a detailed analysis of figure of merits, performing thermal modeling, and executing small-signal-modeling to demonstrate operational efficacy. In-depth mathematical analysis of both continuous conduction mode (CCM) and discontinuous conduction mode (DCM) are conducted. The detailed comparison analysis shows that the suggested converter outperforms traditional converters in voltage-gain, voltage-stress, device-utilization, and reliability. Additionally, a 400 W, 220 V laboratory-scaled prototype shows 68 % reliability after 20 years. The hardware test outcomes validate the accuracy of both the mathematical investigation and simulation findings.

Abstract
Spintronic terahertz emitters (STEs), based on optical excitation of nanometer thick ferromagnetic/heavy metal (FM/HM) heterojunctions, have become important sources for the generation of terahertz (THz) pulses. However, the efficiency of the optical-to-THz conversion remains limited. Although optical techniques have been developed to enhance the optical absorption, no investigations have studied the application of THz cavities. Here, to enhance the THz efficiency of STEs in a selected THz spectral range, FM/HM structures are realized on ultra-thin sapphire layers with metallic mirrors to create λ/4 THz resonant cavities. THz emission time domain spectroscopy of these STE/sapphire/mirror heterostructures, with sapphire thicknesses ranging from 110 µm to 25 µm, shows enhancement of the emitted THz field that fits the λ/4 cavity resonance with up to a doubling of the field in the spectrum, and in agreement with temporal simulations of the emitted THz pulse. By taking advantage of birefringent materials, we further show the potential of control of the polarization state of the emitted THz pulse. This work shows the potential of enhancing and engineering THz emission from STEs using THz cavities that can be controlled over a broad spectral range, which can be easily combined with optical cavities.

Published: March 2024

Abstract
Oxidative degradation of 1,2-dichlorobenzene using different loadings of metal (Mn, Ni, V, and Fe) supported on CeO2 was studied. All metal (Mn, Ni, V, and Fe) loaded CeO2 catalysts were synthesized using the method called wet impregnation and the as-synthesized catalyst materials were characterized using different analytical instruments such as FT-IR, SEM-EDX, XRD, BET, ICP-OES, and TEM methods. The oxidation reactions of 1,2-dichlorobenzene were studied by bubbling substrate (1,2-dichlorobenzene) with ozone (0.0794 mg/L) into a glass reactor via a porous bubbler of porosity 2 over a period of 24 h. A 2.5 % Fe/CeO2 catalyst was found to be the most active catalyst with a percentage conversion of 62 % within 24 h of ozonation. The oxidation products were identified using GC-MS and FT-IR spectroscopy was used to study the functional groups present in the ozonation product. The ozonation products that were identified are mucochloric acid and 3,4-dichloro-2,5-furandione. All the V loaded on CeO2 catalysts produced 100 % mucohloric acid at the end of ozonation (24 h).
Peptides for therapeutic applications – challenges and chances
Authors: Ruggirello Chiara , Mörl Karin , Beck-Sickinger Annette G. 
Published: March 2024

Abstract
Peptides have beneficial properties for therapeutic applications due to their excellent target specificity, high affinity and activity, low toxicity and predictable metabolism. Thus, they became an important tool for research and medical purpose. However, peptides are fragile molecules, therefore, in order to be used as therapeutic agents they need to be stabilised by non-peptidic modifications. Required improvements of these peptide properties include longer half-life, higher bioavailability, increased potency and efficiency. Strategies to achieve these goals have been identified in the last years, with synthetic strategies to obtain sufficient amounts becoming increasingly important. In this review, peptides are discussed with respect to their therapeutic applications. Examples from glucagon-like peptide 1 receptor agonists are shown. Peptides are compared to small molecules and antibodies with respect to advantages and disadvantages in therapeutic applications.
A survey of Polish ASR speech datasets
Authors: Junczyk Michał 
Published: March 2024

Abstract
Access to speech datasets is essential for the effective use of modern ASR systems in low-resource languages like Polish. However, the lack of centralized information and metadata describing available datasets poses a significant challenge to researchers and practitioners. In this paper, we address this issue by presenting the most comprehensive survey of Polish ASR speech datasets to date. We manually curated information on 53 publicly available datasets and annotated them with 61 attributes, providing a comprehensive catalog of these resources. The catalog facilitates the discovery and evaluation of available datasets, enabling researchers to identify datasets that suit their specific needs. It also enables the identification of gaps in the existing datasets, which may inform future research directions. The catalog is open and community-driven, which means that new data sets can be added and issues can be reported, ensuring its continued relevance and usefulness to the ASR community. Our work contributes to improving the accessibility and usability of ASR systems in low-resource languages such as Polish.

Undiagnosed adrenal insufficiency as a cause of premature death in glucocorticoid users
Authors: Einarsdottir Margret J , Trimpou Penelope , Johannsson Gudmundur , Ragnarsson Oskar 
Published: March 2024

Objective
It is unknown whether glucocorticoid (GC)-induced adrenal insufficiency may cause premature mortality in GC users. We conducted a retrospective cohort study to investigate if undiagnosed and undertreated GC-induced adrenal insufficiency is a contributor to premature death in GC users.

Methods
Information on dispensed prescriptions in West Sweden from 2007 to 2014 was obtained from the Swedish Prescribed Drug Register. Cause of death was collected from the Swedish Cause of Death Register. Of 223,211 patients who received oral GC prescriptions, 665 died from sepsis within 6 months of their last prescription. Three hundred of these patients who had died in hospital were randomly selected for further investigation. Medical records were initially reviewed by one investigator. Furthermore, two additional investigators reviewed the medical records of patients whose deaths were suspected to be caused by GC-induced adrenal insufficiency.

Results
Of 300 patients (121 females, 40%), 212 (75%) were prescribed GC treatment at admission. The mean age was 76 ± 11 years (range 30–99). Undiagnosed or undertreated GC-induced adrenal insufficiency was considered a probable contributor to death by at least two investigators in 11 (3.7%) patients. In five of these 11 cases, long-term GC therapy was abruptly discontinued during hospitalization. Undiagnosed or undertreated GC-induced adrenal insufficiency was considered a possible contributing factor to death in a further 36 (12%) patients.

Conclusion
GC-induced adrenal insufficiency is an important contributor to premature death in GC users. Awareness of the disorder during intercurrent illness and following cessation of GC treatment is essential.

BACKGROUND AND OBJECTIVESPopulation-wide racial inequities in child health outcomes are well documented. Less is known about causal pathways linking inequities and social, economic, and environmental exposures. Here, we sought to estimate the total inequities in population-level hospitalization rates and determine how much is mediated by place-based exposures and community characteristics.METHODSWe employed a population-wide, neighborhood-level study that included youth &lt;18 years hospitalized between July 1, 2016 and June 30, 2022. We defined a causal directed acyclic graph a priori to estimate the mediating pathways by which marginalized population composition causes census tract-level hospitalization rates. We used negative binomial regression models to estimate hospitalization rate inequities and how much of these inequities were mediated indirectly through place-based social, economic, and environmental exposures.RESULTSWe analyzed 50 719 hospitalizations experienced by 28 390 patients. We calculated census tract-level hospitalization rates per 1000 children, which ranged from 10.9 to 143.0 (median 45.1; interquartile range 34.5 to 60.1) across included tracts. For every 10% increase in the marginalized population, the tract-level hospitalization rate increased by 6.2% (95% confidence interval: 4.5 to 8.0). After adjustment for tract-level community material deprivation, crime risk, English usage, housing tenure, family composition, hospital access, greenspace, traffic-related air pollution, and housing conditions, no inequity remained (0.2%, 95% confidence interval: −2.2 to 2.7). Results differed when considering subsets of asthma, type 1 diabetes, sickle cell anemia, and psychiatric disorders.CONCLUSIONSOur findings provide additional evidence supporting structural racism as a significant root cause of inequities in child health outcomes, including outcomes at the population level.

Published: March 2024

Background. The current need for optimization of salvage treatment methods is dictated by the growing expansion of indications for radical prostatectomy in many centers in the developed countries of the world.Aim. To evaluate the effectiveness, toxicity, and technical characteristics of high-dose rate brachytherapy in treatment of local prostate cancer (PCa) recurrences after radical prostatectomy.Materials and methods. Between January 2015 and December 2020, salvage high-dose rate brachytherapy was performed in 17 patients at the Russian Scientific Center of Roentgenology and Radiology for local recurrence of PCa after radical prostatectomy. All patients underwent multiparametric magnetic resonance imaging of the pelvis at the stage of primary diagnosis in order to determine macroscopic tissue component in the prostate bed area. To rule out regional and distant metastases, all patients underwent positron emission tomography with 18F- or 68Ga-labeled prostate-specific membrane antigen. All patients included in the study underwent perineal biopsy of the prostate bed and seminal vesicles.Results. Median follow-up in the treatment group was 35.7 (24–54) months. Overall survival was 100 %. Prostatespecific antigen-specific survival was 88.2 %. There were no local recurrences of PCa in the treatment group. In patients with local PCa recurrence, significant predictors of treatment failure were the presence of clinically extremely high risk of progression at initial diagnosis (p = 0.003), development of biochemical relapse up to 24 months after main treatment (p = 0.001), and increased blood level of prostate-specific antigen above 10 ng/mL during registration of biochemical relapse (p = 0.002).Conclusion. High-dose rate brachytherapy is a safe and effective salvage treatment for local recurrence of PCa after radical prostatectomy. In addition to the brachytherapy technique, the diagnostic stage is also of great importance providing visualization of the exact location of tumor recurrence.
