IntroductionMaster athletes are examples of successful aging. It is not clear whether it is the competitive-oriented training or just the amount of total regular exercise that reduces the age-related decline in physiological functions. We aimed to compare health-related parameters in competitive (C) and physically active older adults (A) that performed the same weekly physical activity (PA) amount.MethodsSeventeen C and 17 A were matched for age (8 and 9 male participants under and over 70 years old respectively, for both groups) and weekly PA amount (GPAQ). Body composition, leg and arm maximal strength, balance and reaction time were measured; moreover, leg and arm exercise efficiency, estimated VO2max, and VO2/HR relationships were evaluated. Perception of life and sleep quality was also assessed through specific questionnaires (SF-36 and PSQI). The effect of group (C vs. A), age (U70 vs. O70) and their interaction was examined through a Two-Way ANOVA test.ResultsC dedicated more time to vigorous PA compared to A (p = 0.03), while less to moderate daily work (p &lt; 0.01) and active commuting (p = 0.06). C exhibited better body composition (all p &lt; 0.05), higher leg maximal strength (p &lt; 0.05) and a trend for elevated arm strength (p = 0.06). Reaction time, leg and arm cycling efficiency were similar in the two groups (all p &gt; 0.05), while balance reduced in A O70. Estimated VO2max was higher for C in leg cycling (p = 0.05) and remained constant across ages (all p &gt; 0.05). VO2/HR relationship, life and sleep quality did not differ for groups and ages.ConclusionsRegular physical exercise of about 6,000 METs/week seems to have a beneficial effect on health-related parameters, both in non-structured and competitive PA, when compared to sedentary behaviour. However, the older adults engaged in competitive training exhibit further advantages: better body composition, higher arm and leg muscle strength, and higher leg VO2max. This study highlights the importance of encouraging active lifestyles for maintaining long-term health, high levels of life quality perception and reducing age-related decline. However, vigorous training suitability needs to be verified by a team of PA specialists.

BackgroundGastric epithelial neoplasm of the fundic-gland mucosa lineages (GEN-FGMLs) are rare forms of gastric tumors that encompass oxyntic gland adenoma (OGA), gastric adenocarcinoma of the fundic-gland type (GA-FG), and gastric adenocarcinoma of the fundic-gland mucosa type (GA-FGM). There is no consensus on the cause, classification, and clinicopathological features of GEN-FGMLs, and misdiagnosis is common because of similarities in symptoms.Methods37 cases diagnosed with GEN-FGMLs were included in this study. H&amp;E-stained slides were reviewed and clinicopathological parameters were recorded. Immunohistochemical staining was conducted for MUC2, MUC5AC, MUC6, CD10, CD56, synaptophysin, chromograninA, p53, Ki67, pepsinogen-I, H+/K+-ATPase and Desmin.ResultsThe patients’ ages ranged from 42 to 79 years, with a median age of 60. 17 were male and 20 were female. Morphologically, 19 OGAs, 16 GA-FGs, and two GA-FGMs were identified. Histopathological similarities exist between OGA, GA-FG, and GA-FGM. The tumors demonstrated well-formed glands, expanding with dense growth patterns comprising pale, blue-grey columnar cells with mild nuclear atypia. These cells resembled fundic gland cells. None of the OGA invaded the submucosal layer. The normal gastric pit epithelium covered the entire surface of the OGA and GA-FG, but the dysplasia pit epithelium covered the GA-FGM. Non-atrophic gastritis was observed in more than half of the background mucosa. All cases were diffusely positive for MUC6 and pepsinogen-I on immunohistochemistry. H+/K+-ATPase staining was negative or showed a scattered pattern in most cases. MUC5AC was expressed on the surface of GA-FGMs. p53 was focally expressed and the Ki67 index was low (1%–20%). Compared with OGA, GA-FG and GA-FGM were more prominent in the macroscopic view (p &lt; 0.05) and had larger sizes (p &lt; 0.0001). Additionally, GA-FG and GA-FGM exhibited higher Ki67 indices than OGA (p &lt; 0.0001). Specimens with Ki-67 proliferation indices &gt;2.5% and size &gt;4.5 mm are more likely to be diagnosed with GA-FG and GA-FGM than OGA.ConclusionGEN-FGMLs are group of well-differentiated gastric tumors with favourable biological behaviours, low cellular atypia, and low proliferation. Immunohistochemistry is critical for confirming diagnosis. Compared with OGA, GA-FG and GA-FGM have larger sizes and higher Ki67 proliferation indices, indicating that they play a critical role in the identification of GEN-FGML. Pathologists and endoscopists should be cautious to prevent misdiagnosis and overtreatment, especially in biopsy specimens.
An Enhanced Multiple Unmanned Aerial Vehicle Swarm Formation Control Using a Novel Fractional Swarming Strategy Approach

Published: June 2024

This paper addresses the enhancement of multiple Unmanned Aerial Vehicle (UAV) swarm formation control in challenging terrains through the novel fractional memetic computing approach known as fractional-order velocity-pausing particle swarm optimization (FO-VPPSO). Existing particle swarm optimization (PSO) algorithms often suffer from premature convergence and an imbalanced exploration–exploitation trade-off, which limits their effectiveness in complex optimization problems such as UAV swarm control in rugged terrains. To overcome these limitations, FO-VPPSO introduces an adaptive fractional order β and a velocity pausing mechanism, which collectively enhance the algorithm’s adaptability and robustness. This study leverages the advantages of a meta-heuristic computing approach; specifically, fractional-order velocity-pausing particle swarm optimization is utilized to optimize the flying path length, mitigate the mountain terrain costs, and prevent collisions within the UAV swarm. Leveraging fractional-order dynamics, the proposed hybrid algorithm exhibits accelerated convergence rates and improved solution optimality compared to traditional PSO methods. The methodology involves integrating terrain considerations and diverse UAV control parameters. Simulations under varying conditions, including complex terrains and dynamic threats, substantiate the effectiveness of the approach, resulting in superior fitness functions for multi-UAV swarms. To validate the performance and efficiency of the proposed optimizer, it was also applied to 13 benchmark functions, including uni- and multimodal functions in terms of the mean average fitness value over 100 independent trials, and furthermore, an improvement at percentages of 29.05% and 2.26% is also obtained against PSO and VPPSO in the case of the minimum flight length, as well as 16.46% and 1.60% in mountain terrain costs and 55.88% and 31.63% in collision avoidance. This study contributes valuable insights to the optimization challenges in UAV swarm-formation control, particularly in demanding terrains. The FO-VPPSO algorithm showcases potential advancements in swarm intelligence for real-world applications.

В распространенности дистоций, задержаний последа и мертворождения телят в большей степени участвуют генетические факторы, поскольку показатели заболеваемости у гомозиготных животных выше, чем у коров стада в целом. Поэтому оценка характеристик производителей наиболее эффективна в прогнозировании родовых патологий у коров. Материалом исследования служили данные быков-производителей линий: Рефлекшн Соверинг 0198998, В.Б. Айдиал, Рефлекшн Соверинг 6 и Метза 200. Анализ проводили по отелам у 3482 коров и нетелей в пяти племенных предприятиях Волгоградской, Саратовской и Ленинградской областей. Частота эутоций в исследуемой выборке варьировала от 32,6% до 50,3%, самый низкий процент отмечен у маток, осемененных быками линии В.Б. Айдиал, а самый высокий — в линии Рефлекшн Соверинг 6. Дистоции у коров и нетелей, осемененных спермой быков разных линий, встречались с частотой от 31,6% до 49,5%, где самое низкое значение — у животных линии Метза 200, самое высокое — у особей линии Рефлекшн Соверинг 0198998. Наименьший показатель задержания последа был характерен для линии быка Рефлекшн Соверинг 6 (15,0%), наивысший наблюдался у самок, осемененных спермой быка Метза 200 (22,1%). Самый низкий показатель мертворождения (1,2%) зарегистрирован у коров и нетелей, осемененных спермой быков линии Рефлекшн Соверинг 0198998, самый высокий (2,3%) — у маток, осемененных спермой быков линии Метза 200.
Genetic factors are involved in the prevalence of dystocia, placenta retention and stillbirth of calves, because the incidence in homozygous animals is higher than in other cows. Therefore, the evaluation of the characteristics of breeding bulls is most effective in predicting reproductive pathologies in cows. The material was the data of bulls of the lines: Reflection Sovering 0198998, V.B. Idial, Reflection Sovering 6 and Metza 200. The analysis was carried out on calving in 3482 cows and heifers in 5 breeding enterprises of the Volgograd, Saratov and Leningrad regions. The frequency of eutocia in the studied sample ranged from 32.6% to 50.3%, the lowest percentage was observed in queens of the V.B. Ideal line, and the highest in the Reflection Sovering 6 line. Dystocia in cows and heifers inseminated with sperm from bulls of different lines occurred with a frequency from 31.6% to 49.5%, where the lowest value was in animals of the Metza 200 line, the highest was in individuals of the Reflection Sovering 0198998 line. The lowest percentage of placenta retention was found in representatives of the Reflection Sovering 6 line (15.0%), the highest was in animals of the Metza 200 line (22.1%). The lowest stillbirth rate (1.2%) was recorded in cows and heifers of the Reflection Sovering 0198998 line, the highest (2.3%) — in queens of the Metza 200 line.

In the era of digitalization, where the development of technology is closely linked to economic prosperity, it is important to realize the threats posed by the modern world. Indeed, digital transformation opens up new horizons for public spheres of life, intertwining innovative technologies with everyday tasks, actively stimulating social progress. However, as dependence on new technologies increases, the impact of digital threats on economic stability and security increases. The attractiveness of such incidents is based on the relative cheapness and accessibility, which makes them more preferable for intruders compared to other types of crimes. Various kinds of attacks and malicious actions, such as viruses, phishing, malware, cyberattacks, can disrupt not only the work of companies, but also undermine their financial situation as a whole. At this stage, the problem of digital threats is turning into a global phenomenon affecting everyone – from ordinary citizens to large companies and government agencies. It is important to be aware of this problem, because without proper counteraction to these challenges, economic losses from cybercrimes will only increase. Preventing such attacks and reducing their consequences requires a comprehensive approach. That is why the article considers not only the question of what negative consequences digital threats have, but also suggests the necessary, according to the authors, methods and strategic solutions aimed at reducing economic losses in the process of constantly changing conditions.

Abstract
We investigated the effects of tailored voltage waveform (TVW) discharges on the deposition of hydrogenated amorphous carbon (a-C:H) films in CH4/Ar capacitively coupled plasma. TVW discharges employ two driving radio frequencies (13.56 MHz and 27.12 MHz) and control their phase shifts to independently regulate ion bombardment energy (IBE) and ion flux. In this study, a-C:H films were deposited by changing DC-self bias with phase shift and constant applied voltage peak-to-peak. Additionally, we investigated phase-resolved optical emission spectroscopy (PROES) for plasma characterization. As a result, plasma-enhanced CVD (PECVD) for a-C:H films using TVW discharges realize control of film properties such as mass density, sp3 fraction, and H content, while keeping the deposition rate constant. Thus, it is suggested that TVW discharges realize the independent control of IBE and ion flux with high accuracy, highlighting its utility in a-C:H film depositions.

Mual dan muntah pasca operasi/ Post Operative Nuasea and Vomiting (PONV) sering terjadi pada pasien post sectio caesarea (SC) dengan spinal anastesi dengan prevalensi 1- 43% pada wanita dengan SC di bawah pengaruh spinal anestes. Terapi farmakologi tidak memuaskan karena tidak bisa sepenuhnya memperbaiki PONV. Akupresur merupakan terapi komplementer yang diduga dapat mengurangi mual dan muntah dengan melepaskan endorphine. Penelitian ini bertujuan untuk membuktikan pengaruh akupresur terhadap mual dan muntah pada pasien pasien sectio caesarea dengan spinal anestesi. Penelitian ini merupakan True Eksperiment, pre test and post test control group design. Hasil penelitian diperoleh perbedaan PONV yang signifikan (p<0,001). pada kelompok intervensi. Sebelum intervensi pada jam ke 0 post operasi, rerata PONV adalah 3,03, yang mengalami penurunan signifikan menjadi 0,77 pada jam ke 6 dan 0,02 pada jam ke 12 post operasi. Terdapat perbedaan signifikan mual dan muntah pada pasien postsectio caesarea dengan spinal anestesi antara kelompok intervensi dan kelompok kontrol p<0,05. Dapat disimpulkan bahwa pemberian intervensi akupresur pasca operasi sectio caesarea dengan spinal anestesi berpengaruh terhadap penurunan mual dan muntah pasca operasi.
An ultra-low noise fully-differential amplifier
Authors: Spinelli Enrique M. , Haberman Marcelo A 
Published: June 2024

A general-purpose instrumentation amplifier must be dc-coupled and have
a differential input to handle both differential and single-ended input
signals. It also must exhibit low input noise in both voltage and
current, to accommodate a wide range of signal source impedances.
Additionally, having a differential output is desirable to allow direct
connection to current high-resolution analog-to-digital converters
(ADCs) which have differential inputs. There are commercially available
devices with en voltage noise spectral densities as low
as 1 nV √Hz ⁄ but present high en current noise spectral
densities in of a few pA/√Hz. On the other hand, there
are also devices with in as low as a few fA/√Hz but
presenting en around 10 nV/√Hz. To obtain low values
of both en and in , a fully differential
circuit topology combining discrete Junction Field Transistors (JFET)
and Operational Amplifiers (OA) is proposed. Design equations, stability
analysis, and experimental results are presented. As an example, a fully
differential instrumentation amplifier has been designed, built, and
tested showing en <1 nV/√Hz @1 kHz
and in <10 fA/√Hz @1 kHz. The proposed
topology finds applications such as front ends for measuring and testing
instruments, industrial instrumentation, and audio circuits.

Published: June 2024

Phenols are well-known noxious compounds, that are often found in various water sources. In this research, a new method was used to determine the total phenol by using microfluidic paper-based (µPAD), with a smartphone Sensor. It is portable, inexpensive, and environmentally friendly. The paper was prepared using filter paper by the cutting method. The reagent was dried on the paper. The color sensor of the smartphone device was used as the color intensity sensor of the samples through the images captured by the smartphone through software downloaded to the phone. The focus of the samples is measured from the RGB value of the images taken from the (iPhone 14) device, where each image represents a specific focus. The calibration curve for this method was in the range of M (0.00016–0.5), the correlation coefficient (R2) was equal to (0.9753), the limit of detection was in the amount of (0.000032) M, and the relative standard deviation (RSD%) for the concentration was (0.02) M, for which the examination was repeated (10) times and its value was (0 %), and the recovery value (Recovery%) was equal to (100 %). The method was successfully applied for the determination of total phenols in wastewater.
