Authors: Liang Shujun , Cheng Jing , Zhang Jianwei 
Published: December 2021

Abstract
Wireless human body sensor networks are widely used, but because of hardware and environmental constraints, their nodes have problems such as unsustainable energy and weak computing capabilities. To further improve the efficiency of data aggregation for health monitoring, a fuzzy clustering based data aggregation algorithm is presented. Based on the fuzzy clustering algorithm of distributed wireless sensors, this work analyzes the processing mechanism of distributed data and introduces an optimal weighted weighting algorithm, thereby obtaining the optimal weight distribution coefficient of each sensor, results of node variance evaluation, and corresponding data aggregation through distributed data processing. The proposed algorithm is of great significance to improve the accuracy of data collection and reduce the overall energy consumption of the network.

Abstract
A new species of dorid nudibranch, Doris adrianae sp. nov. is described, from the Ría de Ferrol (NW Iberian Peninsula) on rocky bottoms, between 11 and 20 m deep, where the sponge Polymastia boletiformis (Lamarck, 1815) on which it feeds is common. The new species is oval-shaped and yellow to yellow-orange in colour, with the back covered by rounded tubercles of various sizes, reinforced by tegumentary spicules. It is characterised by numerous integumentary and fusiform calcareous spicules, mainly grouped in multispicular bundles that give it a complex and very dense skeletal structure, giving the animal great consistency without losing flexibility. In addition, it differs from other known species of the genus Doris Linnaeus, 1758 by various external and internal characters, mainly by the colouring and tubercles of the body, characters of the radula and of the digestive and reproductive systems. Doris adrianae sp. nov. also presents a marked genetic distance in the barcode fragment (cox1-5') with other species of the genus Doris.

Published: December 2021

ABSTRACTThis research investigated the interaction effects between gender and Learner-Centered Teaching Strategies toward learners' writing performance. The study was a quasi-experiment using tests as the research instrument. The participants were 72 learners of the English Department at a state institution consisting of 34 males and 38 females. The class was classified into two parts: experiment groups consisting of self-directed learning class (SDL), discovery learning class (DL), and small group discussion class (SGD); and a control group: lecturing class (L). A two-way ANOVA was used for data analysis. The findings confirmed a significant difference by gender (F=10.629. Sig. 0.002<0.05); and Learner-Centered Teaching Strategies F=20.658. Sig. 0.000<0.050) on the learners' writing performance. It also indicated that females (means score 73.46) were higher than males (means score 64.45). In contrast, no interaction effect simultaneously occurred among gender and the Learner-Centered Teaching Strategies (F 2.70) = 2.301. Sig. 0.086>0.050). Both of them did not contribute simultaneously to writing performance. Lastly, the r squared was 0.574 indicating a high correlation of teaching strategies and gender (57%). The teachers were suggested to apply learner-centered teaching strategies in an L2 writing class at a higher education level.ABSTRAKPenelitian ini menyelidiki pengaruh interaksi antara gender dan strategi pengajaran terpusat pada peserta didik terhadap kinerja menulis peserta didik.

Authors: Schupmann Will , Li Xiaobai , Wendler David 
Published: December 2021

BACKGROUND AND OBJECTIVESCritics argue that it is unethical to expose children to research risks for the benefit of others, whereas many regulations permit “net-risk” pediatric research but only when the risks are minimal. In the present survey, we assessed whether the US public agrees with these views and whether the US public’s views regarding the acceptability of net-risk pediatric research are influenced by its social value.METHODSA 15-minute survey of a nationally representative sample of US adults. Participants were randomly assigned to 1 of 4 hypothetical scenarios involving procedures that pose increasing levels of risk. To assess whether respondents’ views on the acceptability of the risks is influenced by the social value of the research, in each of the 4 scenarios we described the respective procedure being used in 3 studies with increasing levels of social value.RESULTSA total 1658 of the 2508 individuals who were sent the survey link participated (response rate = 66.1%). Approximately 91% approved of a research blood draw in minors, and ∼69% approved of a research bone marrow biopsy. The proportion who indicated that the respective procedure was acceptable increased as the study’s social value increased. This effect was significantly stronger for studies which pose greater risks compared with studies with lower risks (P &lt; .001).CONCLUSIONSThe vast majority of the US public supports net-risk pediatric research that poses minimal risk, and a majority supports net-risk pediatric research that poses somewhat greater risks, provided it has high social value. These findings offer important information for assessing when it is acceptable to conduct net-risk pediatric research.

Abstract
A sensitive and accurate LC-MS/MS method was developed and validated for the simultaneous quantification of rivaroxaban (RIV) and sitagliptin (SIT) in rat plasma using apixaban as internal standard (IS). An Agilent Eclipse plus C18 column (2.1 × 100 mm, 3.5 µm, Agilent) was used for chromatographic separation with isocratic elution. Multiple reaction monitoring (MRM) using positive-ion ESI mode to monitor ion transitions of m/z 436.8→144.9 for RIV, m/z 407.7→173.8 for SIT, m/z 459.8→442.8 for IS. The procedure of method validation included selectivity, linearity, precision, accuracy, matrix effect, extraction recovery and stability were conducted according to the guidelines of EMA and FDA. The results indicated that no obvious drug-drug interactions occurred might be owing to their differences in metabolic pathways.

Published: December 2021

Background and Study Aim. Although Kinesiotape is widely used by athletes, information about its effect is unclear. Its effect on postural control might directly affect an athlete's performance. In this study, it is aimed to find out whether ankle Kinesiotaping in taekwondo athletes affects postural control.
Material and Methods. Twenty-four healthy university students – taekwondo athletes (12 females, 12 males) were included in the study voluntarily (Age 21.00 ± 1.53 years; height 173.33 ± 7.29 cm; body weight 63.41 ± 9.41 kg). Kinesiotape was carried out to the dominant ankle of the participants. Kinesiotape was applied supportively to peroneus longus, peroneus brevis, and tibiofibular ligament. All participants were taken to postural control measurements twice with Kinesiotape (KT) and without KT. Postural control was measured using the Biodex Balance System with eyes open (EO) and eyes closed (EC). Overall Stability Index (OSI), anterior-posterior sway (AP) and medio-lateral sway (ML) scores were used in the evaluation of postural control. Wilcoxon test was used to compare balance scores under EO condition, and the t-test was used for dependent groups to compare balance scores under EC condition.
Results. In EO condition, no significant difference was found between OSI, AP, and ML scores of the taekwondo athletes with KT and without KT (p > 0.05). In EC condition, no significant difference was found between OSI, AP, and ML scores of male taekwondo athletes with KT and without KT (p > 0.05). It was found that Kinesiotape in EC condition decreased OSI and AP sway scores in female taekwondo athletes (p < 0.05).
Conclusions. It was determined that ankle Kinesiotaping of taekwondo athletes did not change the postural balance in EO condition. In EC condition it did not change the postural sway of male taekwondo athletes, but it improved the postural control performances of female taekwondo athletes.

Background and Study Aim. The objective of the study was to determine the peculiarities of impact of sports specialization on 3rd-year female students’ functional and motor fitness.
Materials and methods. The study involved 3rd-year female students of the Donbas State Engineering Academy in Kramatorsk, who practiced badminton (n = 43), aerobics (n = 43), and callanetics (n = 43). To solve the tasks set, the following research methods were used: analysis of scientific literature, pedagogical observation, pedagogical testing; index method and medical-biological methods. Pedagogical methods were used to study the peculiarities of students’ functional state of the body and motor abilities; for data processing discriminant analysis was used. Sectional classes were held in groups according to the schedule – twice a week.
Results. The study revealed the peculiarities of impact of attending badminton, aerobics, and callanetics sports sections on the level of 3rd-year female students’ functional and motor fitness. The female students who play badminton show better results in the 100-meter dash and the Standing long jump. In the exercise “Push-ups”, better results are shown by the female students who do aerobics.
Conclusions. The results of classification of students by the level of motor and functional fitness and the analysis of multidimensional averages (centroids) point to the peculiarities of dynamics of female students’ state depending on sports specialization. The results of the following tests are most important for differentiated assessment of the state of motor and functional fitness at the first level: Romberg test (r = 0.662), 100-meter dash (r = 0.491), Push-ups (r = 0.491). At the second level – Stange test (r = 0.417), Standing long jump (r = 0.412).

Photo-Fenton-like oxidation of organic substances is one of the key advanced oxidation processes based on the reversible Fe2+↔Fe3+ transition and the generation of a strong oxidant ·OH in the presence of H2O2 and is currently considered as a promising method for the purification of polluted aqueous media. However, the absence of effective and stable photocatalysts of this process, operating under the action of visible light, necessitates the exploratory studies, mainly among iron oxides and ferrites of various compositions and structures. In this work, using the method of solution combustion followed by heat treatment in air the heterojunction nanocomposites based on ytterbium orthoferrite and cerium dioxide of the composition o-YbFeO3/h-YbFeO3/CeO2 (0–20 mol.%) with high absorption in the visible region and advanced photo-Fenton-like activity were obtained. The nanocomposites were studied by EDS, SEM, XRD, BET, and DRS methods. The photo-Fenton-like activity of the nanocomposites was investigated during the degradation of methyl violet under the action of visible (λmax = 410 nm) radiation. As a result, the formation of I-type heterojunction based on stable rhombic (55.4–79.0 nm) and metastable hexagonal (19.5–24.0 nm) modifications of ytterbium orthoferrite (o-YbFeO3 and h-YbFeO3, respectively) and cubic cerium dioxide CeO2 (13.2–19.2 nm) nanocrystals was established. It was shown that the obtained nanocomposites had foamy morphology and were characterized by a specific surface in the range of 9.1–25.0 m2/g, depending on the CeO2 content. It was found that nanocrystalline components were chemically and phase-pure, uniformly spatially distributed over the nanocomposite, and had multiple contacts with each other. Based on this fact and the established electronic structure of the nanocomposite components, the formation of I-type heterojunction with the participation of o-YbFeO3 (Eg = 2.15 eV), h-YbFeO3 (Eg = 2.08 eV), and CeO2 (Eg = 2.38 eV) was shown, the presence of which increased photocatalytic activity of the resulting nanocomposite. The optimal content of CeO2 in the nanocomposite was 5%, and the o-YbFeO3/h-YbFeO3/CeO2–5% sample was characterized by the highest rate constant of photo-Fenton-like degradation of methyl violet under the action of visible light equal to k = 0.138 min–1, which was 2.5 to 5 times higher than for nanocomposites based on ytterbium orthoferrite. The obtained results obtained indicate that the developed nanocomposites can be considered as a promising basis for the advanced oxidation processes for the purification of aqueous media from organic pollutants.

Efficiency of ultrasonic treatment of polysaccharide from brown algae
Authors: Suprunchuk Victoria E. 
Published: December 2021

Ultrasonic exposure can be used for depolymerization of brown algae polysaccharides. However, its effectiveness depends on several factors, including cavitation activity in the treatment medium. Therefore, the purpose of the work was to determine the cavitation activity and the effectiveness of the ultrasonic exposure to fucoidan in order to optimize the processing processes of polysaccharide from brown algae. A change in cavitation activity was revealed depending on the composition of the processing environment, as well as on the intensity of ultrasonic exposure with a constant frequency of the ultrasonic wave. Similar dynamics of change of cavitation activity were established at the intensity of ultrasonic treatment of 100 and 133 W/cm2 with amplification of electric signal at the increase of ultrasound intensity. The use of SDS in the processing medium led to an increase in cavitation activity to 14.9±0.47 mV. Treatment of the fucoidan solution for 40 minutes under various conditions allowed to obtain fractions with a change in the average hydrodynamic particle diameter from 113 nm (100 W/cm2) to 85 nm (200 W/cm2) and 124 nm (SDS).

Objective: To evaluate the results of retroperitoneal lymph node dissection (RPLND) in patients with advanced non-seminomatous germ cell testicular tumors (NSGCT) and incomplete serological and radiological response to chemotherapy (CT).Materials and methods: The study included 96 patients with advanced NSGCT who underwent RPLND in N.N. Blokhin Russian Cancer Research Center in 1983-2020. The median age was 27 (15-57) years. All patients (n = 96, 100,0 %) received first-line cisplatin-based CT. Fifty-eight patients (60,4%) received second-line CT. After completion of CT, all patients presented with elevated levels of AFP and/or hCG and detectable tumor lesions (retroperitoneal metastases only in 77 cases (80,2 %), metastases in the retroperitoneal space and other sites in 19 cases (19,8%)). All patients underwent the follow-up surgery after CT completion: RPLND in 96 cases (100,0%) and resection of extra-retroperitoneal lesions in addition to RPLND in 8 cases (8,3%). In total, 29 (30,2%) of 96 patients received CT following surgery. The median follow-up was 39,4 (1-284) months.Results: Postoperative complications were reported in 10 (10,6%) patients, including grade 3-4 in 3 patients (3,1%). The mortality rate was 1,1%. The complete resection of retroperitoneal tumor lesions was performed in 80 cases (83,3 %), resection of all detectable tumor lesions in 69 cases (71,9%). None of the patients achieved complete response to postoperative CT. Pathological examination of retroperitoneal lesions revealed necrosis and fibrosis, teratomas, and malignant non-seminomatous tumors in 25 (26,0 %), 29 (30,2 %), and 42 (43,8 %) cases, respectively. The long-term overall survival (OS) and cancer-specific survival rates were 60,9 % and 61,7 %, respectively. The relapse-free survival rate in patients who underwent complete resection reached 65,2 %, the progression-free survival rate in patients who underwent incomplete resection was 35,9 %. A multivariate analysis revealed the following independent predictors of unfavorable OS: RPLND after second-line CT (odds ratio [OR] 4,667 (95% confidence interval [CI]: 1,987-10,961)), presence of a residual retroperitoneal mass of a malignant non-seminomatous tumor (OR 3,081 (95% CI: 1,178-8,055), and incomplete removal of residual lesions after CT (OR 4,445 (95% CI: 1,813-10,899)).Conclusion: Post-CT RPLND may be considered a viable option in the selected group of advanced NSGCT patients with an incomplete serological response to CT eligible for complete resection of all detectable tumor lesions.
