El conflicto por la presidencia del brazo militar de Cataluña y sus implicaciones (1693-1706)
Authors: Martí Fraga Eduard
Published: October 2024

En 1693 el Brazo Militar de Cataluña modificaba sus estatutos para afirmar la precedencia del Protector del Brazo por delante de los títulos. La decisión era consecuencia de la pretensión de éstos a preceder al protector en la ceremonia por la beatificación de santa María de Cervelló. Esto provocó un enfrentamiento entre la pequeña y mediana nobleza contra los títulos, los cuales no participaron en el Brazo hasta que se les reconociera su rango. El conflicto guarda puntos de semejanza con el asunto del Banquillo de 1705 entre los grandes de España y Felipe V por la precedencia en las ceremonias por la onomástica de Luis XIV, si bien las dimensiones de ambos conflictos son diferentes. Tras estos enfrentamientos, se dirimía la definición del papel que tenían los títulos en el gobierno del Estado. Este trabajo pretende mostrar cómo, a partir de un mismo acontecimiento, las respuestas de las noblezas catalanas y castellanas fueron diferentes y las consecuencias que esto tuvo.

Authors: Isaacs Kim L. , Sayed Christopher J.
Published: October 2024

Inflammatory bowel disease (IBD) is associated with extraintestinal manifestations that can affect multiple body systems. Extraintestinal manifestations (EIMSs) are seen in up to 50% of patients with IBD. Skin involvement is particularly common occurring in up to 15%–20% of patients. Skin reactivity presents in multiple forms with unique pathology. Therapy for IBD also may affect the skin directly through inflammatory processes or indirectly because of skin infections. This review will concentrate on the most common nonmalignant dermatologic conditions associated with IBD with a focus on prevalence, diagnostic approaches, and management strategies.

Published: October 2024

Weed infestation poses a significant challenge in sesame cultivation, leading to yield losses and decreased economic returns for farmers. The present study comprehensively analyses various weed control approaches, including allelopathic interaction with integrating herbicides and hand-weeding practices. The experiment was conducted at the Agriculture Farm, SOA, Odisha, during the summer of 2023 with 10 weed management treatments in RBD with 3 replications. The objective was to study different weed management practices, including the sole and sequential application of herbicides and botanicals, to control diverse weeds and enhance summer sesame growth, yield and profitability. The dominance of Digitaria sanguinalis (L.) Scop., Echinochloa colona (L.) Link. and Poa annua L. among grassy weeds and Melochia corchorifolia L., Cleome viscosa L. and Cassia tora L. among the broadleaved weeds were evident in summer sesame. The execution of different treatments showed that integrated use of aqueous leaf extract of Parthenium hysterophorus at 5 % concentration, followed by quizalofop-p-ethyl at 50 g/ha, was found on par with hand-weeding and brought down the weed count and biomass, which in turn increased the growth of summer sesame. The maximum yield of (793 kg seed/ha and 3035 kg stalk/ha) was registered under twice hand weeding. It was comparable with the spraying of aqueous leaf extract of Parthenium hysterophorus at 5 % concentration followed by (fb) quizalofop-p-ethyl at 50 g/ha (772 kg seed/ ha and 2968 kg stalk/ha). Economic analysis of sesame revealed that the maximum return (Rs. 37454/- per ha) and return/rupee (2.28) were recorded with aqueous leaf extract of P. hysterophorus at 5 % concentration fb quizalofop-p-ethyl at 50 g/ha treatment.

Authors: Jing Ru , Zhang Yajuan , Zhuo Shulong
Published: October 2024

Hardware testing has always been the core of hardware development, and improving the performance and efficiency of hardware testing is very important for hardware development. Because hardware quality management is insufficient, many large hardware tools were developed using manual workshop technology in the past and could hardly be maintained. This can lead to the cancellation of the project, causing major personnel and property losses. Improving hardware quality and ensuring security are very complex problems. Hardware testing is usually conducted through manual and automatic testing, and the limitations of manual testing are increasingly obvious. So hardware automatic testing technology has attracted people’s attention in recent years. It has become an important research direction in the field hardware testing and can overcome many problems of traditional testing methods. Strict test rules, based on standards and scores, provide a fully automated test process. With the continuous improvement of network technology, the functions and scope of hardware are constantly enriched and expanded. With the acceleration of hardware updates and development, this has brought a heavy burden to the previous hardware testing work. The purpose of this article was to study the application of machine learning technology in the field of hardware automatic testing and provide an appropriate theoretical basis for optimizing testing methods. This article introduced the research methods of hardware automatic testing technology, introduced three automatic testing framework models, and summarized the application of machine learning in hardware testing. It included hardware security and reliability analysis, hardware defect prediction, and source-based research. Then, this article studied the defect prediction model and machine learning algorithm and constructed a hardware defect prediction model based on machine learning based on the theory. First, the data were preprocessed, and then, the Stacking method was used to build a comprehensive prediction model, and four prediction results evaluation indicators were established. In the experiment part, the defect prediction results of the hardware automatic test model were studied. The results showed that the hardware defect prediction model based on machine learning had higher accuracy, recall rate, F_measure and area under curve. Compared with other models, the average accuracy of the hardware defect prediction model in this article was 0.092 higher, which was more suitable for automatic hardware testing and analysis.

Objectives

Infertility affects approximately 15 % of couples globally, with 50 % cases of male factor infertility. Precise assessment of spermatogenesis is essential for evaluating male infertility. Recent studies suggest serum inhibin B as a promising biomarker for testicular function. This study aims to evaluate the diagnostic utility of serum inhibin B in predicting male infertility, particularly focusing on its relationship with sperm count.

Methods

A cross-sectional study was conducted on 80 adult men (mean age 31.4 ± 6.89 years) presenting with infertility at gynecology and urology outpatient departments. Semen analysis was performed following WHO (2010) guidelines, and serum inhibin B levels were quantified. The correlation between serum inhibin B levels and sperm parameters was assessed using Pearson’s correlation test. Receiver operating characteristic (ROC) curve analysis was employed to evaluate the diagnostic accuracy of serum inhibin B and the inhibin B/FSH ratio for non-obstructive azoospermia (NOA) and oligozoospermia.

Results

A significant positive correlation was observed between serum inhibin B and sperm count (r=0.94, p<0.001). ROC analysis demonstrated that the inhibin B/FSH ratio had the highest diagnostic accuracy for NOA and oligozoospermia (AUC=0.986), with sensitivity of 100 % and specificity of 91.67 %. Serum inhibin B alone also showed high diagnostic value (AUC=0.965 for NOA and 0.969 for oligozoospermia).

Conclusions

Serum inhibin B is a reliable biomarker for assessing male infertility, particularly in evaluating spermatogenic function. The inhibin B/FSH ratio provides superior diagnostic accuracy for NOA and oligozoospermia, offering valuable clinical utility in male infertility diagnosis.

Published: October 2024

The application of process mining opens up a wide range of possibilities for logistics, such as the identification of bottlenecks, the optimization of throughput times and the more efficient use of resources. However, in an area as dynamic and vulnerable as logistics, there are specific challenges that make the application of process mining difficult and therefore require special attention. A structured approach is therefore required to successfully implement process mining in practice. This publication presents a methodology that supports companies in effectively integrating process mining into their internal logistics operations. It includes project initialization, the extraction and preparation of the data to be analyzed, the execution of analyses, the interpretation of the results and the derivation of measures.

Coupling of Slow Oscillations in the Prefrontal and Motor Cortex Predicts Onset of Spindle Trains and Persistent Memory Reactivations
Authors: Darevsky David , Kim Jaekyung , Ganguly Karunesh
Published: October 2024

Sleep is known to drive the consolidation of motor memories. During nonrapid eye movement (NREM) sleep, the close temporal proximity between slow oscillations (SOs) and spindles (“nesting” of SO-spindles) is known to be essential for consolidation, likely because it is closely associated with the reactivation of awake task activity. Interestingly, recent work has found that spindles can occur in temporal clusters or “trains.” However, it remains unclear how spindle trains are related to the nesting phenomenon. Here, we hypothesized that spindle trains are more likely when SOs co-occur in the prefrontal and motor cortex. We conducted simultaneous neural recordings in the medial prefrontal cortex (mPFC) and primary motor cortex (M1) of male rats training on the reach-to-grasp motor task. We found that intracortically recorded M1 spindles are organized into distinct temporal clusters. Notably, the occurrence of temporally precise SOs between mPFC and M1 was a strong predictor of spindle trains. Moreover, reactivation of awake task patterns is much more persistent during spindle trains in comparison with that during isolated spindles. Together, our work suggests that the precise coupling of SOs across mPFC and M1 may be a potential driver of spindle trains and persistent reactivation of motor memory during NREM sleep.

Randolpho Rubenso Goldmano pateikta kritika Kurto Gödelio ontologiniam įrodymui pabrėžė ligi tol praktiškai nepastebėtą šio įrodymo silpnybę. Anot Goldmano, tam, kad samprotavimas būtų iš tiesų sėkmingas, reikalinga sukurti jam taikomąją semantiką. Kadangi Dievą suprantame priskirdami jam konkrečias savybes, viena iš taikomosios semantikos užduočių kaip tik ir yra formalios įrodymo pateikties susiejimas su šiais teologiškai reikšmingais turiniais. Vis dėlto, Goldmano teigimu, mėginimai tai padaryti kelia rimtų iššūkių: bandant išreikšti įrodymą natūralia bei teologiškai tinkama kalba daugybė sakinių joje tampa beprasmiai, todėl pažeidžiamas dvireikšmiškumo principas. Šiame straipsnyje analizuojami skirtingi būdai spręsti šį sunkumą, kaip galutinį siūlymą pateikiant sprendimą, kurio orientyras yra Bertrand’o Russello apibrėžiamųjų deskripcijų teorija: sakinius, figūruojančius šioje natūralios kalbos interpretacijoje, siūloma traktuoti kaip konjunkcijas – tai leidžia atsikratyti beprasmių sakinių bei išsaugoti dvireikšmiškumo principą.

Osteoarthritis (OA) is the most common type of arthritis. It is characterized by the loss of cartilage and pain ultimately leading to difficulty in movement. Glycoprotein osteopontin (OPN) is an essential regulator that plays a critical role in developing osteoarthritis. The study aims to determine the level of OPN in the serum of patients with OA and its correlation with the content of calcium (Ca), phosphorus (P), and magnesium (Mg). The study was conducted on 92 male and female patients aged between 30 and 65, categorized into mild, moderate, and severe groups through clinical examination and X-rays. The control group consist of 58 healthy males and females 30-65-year old. OPN was measured using the ELISA technique, and minerals were estimated using spectrophotometry. It was shown that in OA patients, OPN level increased highly significant when compared with the control group (10.7 ± 3.4 ng/ml) and depended on OA severity. In patients with severe OA, it was higher (47.5 ± 8.1 ng/ml) than in groups with moderate (14.8 ± 4.5 ng/ml) and mild (12.1 ± 3.1 ng/ml) extent of the disease. We showed a significant positive relationship between OPN and phosphorus levels and a negative significant correlation between OPN and calcium, calcium/phosphorus ratio, and magnesium. These findings underscore the potential of OPN as a valuable biomarker for diagnosing the severity of osteoarthritis and monitoring the effectiveness of treatment. Keywords: calcium, magnesium, osteoarthritis, osteopontin, phosphorus.

To date, great attention is paid to sex and age differences in the therapeutic effectiveness of drugs, including those that impact the immune system. Bacteriophage-derived dsRNA is the main component of the medicinal product Larifan, which exhibits interferonogenic activity. This study aimed to estimate the effect of Larifan on the activation status of human peripheral blood monocytes collected from donors of different ages and sex. Blood samples were obtained from the healthy volunteers, divided into 4 groups: young men and young women aged from 20 to 39 years, aged men and aged women from 54 to 69 years old. EDTA-anticoagulated blood samples were exposed to 200 μg/ml Larifan for 30 min, cells were washed and treated to study phagocytic index, ROS generation and expression of phenotypic markers. Only live monocytes selected by flow cytometry were included in the analysis. It was shown that monocytes from young as well as from aged females turned out to be quite inert to the treatment with Larifan. Monocytes from young males after the treatment demonstrated a minor decrease in phagocytic activity and significant down-regulation of ROS generation. Monocytes from aged adults showed clear sex-based differences in the basal cell phenotype. Thus, compared to monocytes from women, the monocytes from men over 50 after the treatment with Larifan showed decreased phagocytic activity and CD86 expression along with increased CD206 expression. Taken together, these results indicate the need for further studies of Larifan focused on developing personalized treatment depending on the age and sex of an individual. Keywords: double-stranded RNA, Larifan, monocytes, phagocytosis, reactive oxygen species, sex and age differences

Published: October 2024

Gut microbiota has complex immune functions, related to different pathologies, including multiple sclerosis (MS).This study evaluated the influence of treatments on gut microbiota in people with MS (PwMS). The research comprised 60 participants, including 39 PwMS and 21 healthy controls (HC). Among the PwMS, 20 were prescribed a disease-modifying therapy (DMT), either interferon beta1a or teriflunomide, while 19 received a combination of classical DMT and an immunoglobulin Y (IgY) supplement. For each participant, two sets of gut samples were collected: one at the study's outset and another after two months. Alpha and beta diversity analyses revealed no significant differences between groups. In comparison to the HC, the MS group exhibited an increase in Prevotella stercorea and a decrease in Faecalibacterium prausnitzii. Following treatment, individuals with MS showed enrichment in Lachnospiraceae and Streptococcus. The second sample, compared to the first one, demonstrated an increase in Bifidobacterium angulatum and a decrease in Oscillospira for individuals with MS. Gut microbiota diversity in PwMS is not significantly different to HC. However, specific taxonomic changes indicate the presence of a dysbiosis state. The use of DMTs and immunoglobulin Y supplements may contribute to alterations in microbial composition, potentially leading to the restoration of a healthier microbiome.
Patterns of protein synthesis in the budding yeast cell cycle: variable or constant?
Authors: No Eun-Gyu , Blank Heidi M , Polymenis Michael
Published: October 2024

Proteins are the principal macromolecular constituent of proliferating cells, and protein synthesis is viewed as a primary metric of cell growth. While there are celebrated examples of proteins whose levels are periodic in the cell cycle (e.g., cyclins), the concentration of most proteins was not thought to change in the cell cycle, but some recent results challenge this notion. The ‘bulk’ protein is the focus of this article, specifically the rate of its synthesis, in the budding yeast Saccharomyces cerevisiae.

The paper analyzes how accountants are portrayed in feature films and series on streaming platforms, including “The Accountant,” “Brooklyn,” “Summer Love,” and “Ozark.” The method is qualitative and is based on Langer (2004), who proposes five stages: (i) identification of the research object and theme; (ii) selection of the film; (iii) external critique of the film; (iv) internal critique of the film; and (v) comparison and content analysis. The results indicate that the stereotype of the accountant prevails, both negatively - as a weak, submissive, and uncreative professional - and positively, portrayed as honest, creative, and idealistic. Furthermore, accountants are often associated with corporate scandals, fraud, and money laundering.

A pesquisa tem como objetivo analisar as despesas da União em 2020 e 2021 com o enfrentamento da pandemia de Covid-19 em busca por indícios de fraudes. O período se caracterizou por um aumento repentino nos gastos públicos, acompanhado de menor rigor nos processos de contratação. A Lei de Newcomb-Benford descreve a frequência dos primeiros dígitos em conjuntos de dados, e é apresentada como uma ferramenta eficaz para identificar anomalias e fraudes em registros financeiros, sendo explorada em diversas áreas, especialmente em auditorias e contabilidade. Realizou-se a comparação das frequências observadas e esperadas para o primeiro, o segundo e os dois primeiros dígitos dos valores empenhados, montante segregado por ano ou modalidade de contratação. A análise se deu por meio de gráficos e testes estatísticos para verificar a aderência das distribuições à Lei de Newcomb-Benford. Os empenhos emitidos no ano de 2020 apresentam melhor aderência que os de 2021, o que sugere maior probabilidade de manipulações ou fraudes no segundo ano de pandemia. Já os gastos decorrentes de pregão tiveram melhor conformidade quando comparados às dispensas de licitação, o que confirmou a percepção de que há maior probabilidade de manipulações ou fraudes nos gastos sem licitação. A pesquisa revela indícios que podem ser interpretados como alertas para órgãos de fiscalização e controle, sendo que a abordagem proposta pode ser utilizada como mecanismo para auditorias de despesas governamentais, auxiliando na seleção de amostras que necessitem de uma análise detalhada por parte de auditores e investigadores.
May Bullying Victimization and Loneliness in Adolescents be Risk Factors for Psychological Resilience?
Authors: İme Yakup
Published: October 2024

Bullying victimization, which has been identified as a common problem among adolescents in recent years, negatively affects adolescents' psychological resilience in many ways. Similarly, loneliness may also be a risk factor for adolescents' psychological resilience. This study aims to examine the relationships between bullying victimization, loneliness and psychological resilience with adolescents. A total of 639 adolescents (415 girls and 224 boys) attending high school participated in the research. Data were collected through the Multidimensional Bullying Victimization Scale, UCLA Short Form and Adolescent Resilience Scale. The presented hypothesis was tested using hierarchical regression analysis. The findings reveal that there are significant relationships between bullying victimization, loneliness and psychological resilience. In addition, the findings show that bullying victimization and loneliness are significant negative predictors of psychological resilience. According to the findings it is recommended to prevent bullying behaviors among adolescents and to conduct studies to improve adolescents' relationships with peers.
Reduction of Total Phenols in Virgin Olive Oil as a Preservation Medium during Cold Storage of Whey Cheese and Tofu

Research background. Virgin olive oil, known as a good source of health-promoting hydrophilic phenols, is traditionally used as a medium for preserving various foods. Phenols in general can form complexes with proteins, but there is little information on the direct contact of virgin olive oil with protein-rich food during long-term storage. In this study, the dynamics of the decline of total phenols in oil used as preservation medium for a traditional (whey cheese skuta) and a modern product (tofu) were compared.
Experimental approach. Pieces of skuta or tofu immersed in virgin olive oil at different food-to-oil mass ratios were stored in the refrigerator for up to 21 days. The oil quality indices, water content and the total count of aerobic mesophilic bacteria in the immersed materials were monitored. To determine the total phenols in the oil, the optimal conditions of the Fast Blue BB test, which is a suitable alternative to the standard method, were tested and selected.
Results and conclusions. The effect of both materials on the indicators of hydrolytic and oxidative deterioration of the oil is almost identical (a gradual decrease), which is most likely due to the continuous release of water from the immersed food. A sharp decrease in total phenols in the oil (by about 50 %) after seven days of storage in contact with both materials indicates a combination of causes (water-to-oil migration and phenol-protein interactions). The form of the rational function is highly representative of the decrease in total phenols during the first seven days of tofu/oil storage, indicating a very rapid interaction with tofu proteins. The preservative effect of virgin olive oil in terms of microbiological spoilage was not observed.
Novelty and scientific contribution. The results of this study contribute to the knowledge on the dynamics of phenol-protein interactions and emphasise the need for further investigations on traditional or newly used protein-rich foods preserved in direct contact with virgin olive oil, taking into account possible changes in the functional, nutritional and sensory properties of phenols and proteins.
An analysis of the phase status of the red locust, Nomadacris septemfasciata (Serville) in KwaZulu-Natal, South Africa

Published: October 2024

Nomadacris septemfasciata is a true locust species and exhibits phase polymorphism, which can potentially lead to outbreaks and plagues. In a recent outbreak of acridids in sugarcane in South Africa, swarms of N. septemfasciata were observed at increasing densities and displaying colouration indicative of the gregarious phase. The aim of this study was to determine the density-dependant phase polyphenism of populations of N. septemfasciata occurring in sugarcane study sites, based on traditional and geometric morphometric measurements, eye stripes and field observations of hopper colour specimens of N. septemfasciata were collected at three locations from May 2012 to May 2013. Three body characters (length measurements) were measured on 594 individuals and the number of dark vertical stripes on the eyes were counted. Lastly, 100 specimens from two locations (25 males and 25 females from each location) were analysed using geometric morphometrics, based on landmarks on wings. Significant differences in E/F ratios were found between locations and seasons, while wing shape also indicated a significant difference between locations (although small) and wing size (centroid size) showed no significant differences. There was a highly significant difference between wing shape of males and females, and the more gregarious males also exhibited higher E/F ratios in many instances. Eye stripes did not appear to be a reliable character and seemed to contradict the E/F ratio values. To our knowledge, this is the first report of using geometric morphometrics, traditional morphometrics and the number of eye stripes to assess phase polyphenism in adult locusts.
A special difference scheme for solving stiff boundary value problems of convective-diffusion transfer
Authors:   Tomsk State University, Zverev Valentin G.
Published: October 2024

The convective-diffusion transfer equation is often found in problems of hydromechanics and heat and mass transfer. The dominance of convection over diffusion and the change in sign of the coefficient at the first derivative lead to the formation of boundary and internal layers with high gradients of the function. This creates serious difficulties in numerical analysis of the problem using traditional difference schemes. The traditional method of approximating the first derivative using central differences at high Peclet numbers can lead to oscillations and violate the monotonicity of the numerical solution. To avoid this problem, it is necessary to significantly reduce the size of grid cells in narrow areas with large gradients of the unknown function. The use of one-sided differences significantly smears the desired solution, due to the viscosity of the scheme, and leads to loss of accuracy. The practical need to solve stiff boundary value problems requires the development and use of computational technologies that guarantee monotonicity, accuracy, and cost-effectiveness in numerical analysis. In this paper, a new special difference scheme is proposed for the numerical solution of a stiff equation of convective-diffusion transfer. The dominant convective term is eliminated from explicit consideration by transforming the equation into self-adjoined form, which permits the use of well-known numerical approximation techniques. The control volume method is used to construct a difference analogue of a differential equation on a three-point template. The resulting scheme is monotonic and conservative. The test examples show great possibilities of the proposed difference scheme for large Peclet numbers on coarse grids in solving stiff boundary value problems of convective diffusion transfer.
