Authors: Siton Rovelyn A. , Baguio Josephine B. 
Published: December 2024

This study aimed to determine the extent of collaborating glitches of students and classroom diplomatic handling of teachers in the classroom. Additionally, to determine the significant relationship between collaborating glitches of students and classroom diplomatic handling of teachers in the classroom in public elementary schools in Panabo District, Division of Davao del Norte. This study employed a descriptive-correlation method with 138 public elementary school teachers as respondents. Data were gathered using a self-made questionnaire directly administered to them. Universal sampling was used, making all population members part of the study. The statistical tools used were mean and product moment correlation or Pearson r. The foregoing conclusions show that the level of collaborating glitches in students was high and oftentimes manifested. Moreover, the level of classroom diplomatic handling of teachers was high and oftentimes manifested. There was no significant relationship between the collaborating glitches of students and the classroom diplomatic handling of teachers. Also, there was a significant influence between collaborating glitches of students and the classroom diplomatic handling of teachers. It is recommended that the teachers may continue to improve the collaborating glitches of students and ensure diplomatic handling by teachers in the classroom to create an environment conducive to learning and personal growth. Collaboration among students often faces challenges such as differing opinions, varying work spaces, or misunderstandings, which can hinder group dynamics and productivity.

AbstractFire warning and monitoring are very important for public safety and environmental protection. However, most of the proposed wind energy conversion devices based on triboelectric nanogenerator (TENG) only work for unidirectional and high‐speed wind and face the challenge of fatigue damage and even failure caused by cyclic stress. Moreover, TENG guided by the theory of fluid dynamics needs further exploration. Herein, a flow‐induced vibration effect based TENG (F‐TENG) for continuously capturing and monitoring multidirectional breeze (1.8–4.3 m s−1) is developed to build a self‐powered intelligent fire detection system (SIFDS). A dynamic model is proposed to study the intrinsic interaction between the electrical properties of F‐TENG and wind. Since the model optimized F‐TENG is more adaptable to wind characteristics, it delivers better performance and higher durability compared with previous studies. Relying on the dynamic model and combining the relationship between F‐TENG's electrical output and wind characteristics, a self‐powered visual wind sensing system is obtained. F‐TENG successfully drives some electronic devices to monitor environmental information, which is expected to provide data for SIFDS to reduce fire hazards. This study can provide an in‐depth understanding of the electromechanical conversion mechanism and large‐scale capture and utilization of breeze energy.

AbstractHerein we report a site‐selective and thiol‐free thiofunctionalization of electron‐rich heteroarenes. After a selective ortho‐magnesiation, the use of S8 followed by an electrophile allows direct access to S‐alkyl or ‐aryl derivatives. In situ oxidation provides the corresponding sulfoxide and sulfone derivatives. Applying this protocol, Cerlapirdine was prepared in 4 steps with 28% overall yield.magnified image

Published: September 2021

AbstractTo clarify the agronomic and physiological characteristics of high‐yielding ratoon rice varieties, 14 rice varieties representing two types (high yield in ratoon crop [RH] and low yield in ratoon crop [RL]) were used as experimental materials. Compared with RL, the grain/leaf ratio of RH at the full heading stage in the main crop was lower. Also, the leaf area duration, net assimilation rate (NAR), crop growth rate (CGR), dry matter weight, photosynthetic rate of flag leaf, and root oxidation activity from the full heading to maturity stage in the main crop were higher. The leaf area index (LAI) and dry matter weight at maturity in the main crop were higher in RH than RL, whereas the rates of LAI attenuation, dry matter translocation and dry matter translocation efficiency (DMTE) from full heading to maturity, and harvest index (HI) in the main crop were relatively lower. The CGR, NAR, dry matter weight from full heading to maturity, and dry matter weight and root oxidation activity at maturity in the main crop were significantly and positively correlated with the yield of the ratoon crop. The rate of LAI attenuation and DMTE from full heading to maturity, grain/leaf ratio at full heading, and HI in the main crop were significantly and negatively correlated with the yield of the ratoon crop. Rational utilization of these agronomic and physiological characteristics would be helpful to screening and breeding high‐yielding rice varieties for ratoon production.

AbstractBackgroundIn people with multiple sclerosis (pwMS), lesions with a hyperintense rim (rim+) on Quantitative Susceptibility Mapping (QSM) have been shown to have greater myelin damage compared to rim‐ lesions, but their association with disability has not yet been investigated. Furthermore, how QSM rim+ and rim‐ lesions differentially impact disability through their disruptions to structural connectivity has not been explored. We test the hypothesis that structural disconnectivity due to rim+ lesions is more predictive of disability compared to structural disconnectivity due to rim‐ lesions.MethodsNinety‐six pwMS were included in our study. Individuals with Expanded Disability Status Scale (EDSS) <2 were considered to have lower disability (n = 59). For each gray matter region, a Change in Connectivity (ChaCo) score, that is, the percent of connecting streamlines also passing through a rim‐ or rim+ lesion, was computed. Adaptive Boosting was used to classify the pwMS into lower versus greater disability groups based on ChaCo scores from rim+ and rim‐ lesions. Classification performance was assessed using the area under ROC curve (AUC).ResultsThe model based on ChaCo from rim+ lesions outperformed the model based on ChaCo from rim‐ lesions (AUC = 0.67 vs 0.63, p‐value < .05). The left thalamus and left cerebellum were the most important regions in classifying pwMS into disability categories.Conclusionrim+ lesions may be more influential on disability through their disruptions to the structural connectome than rim‐ lesions. This study provides a deeper understanding of how rim+ lesion location/size and resulting disruption to the structural connectome can contribute to MS‐related disability.

Key Points
The rate of redo‐coronary artery bypass graft (CABG) nearly doubled from 5.33% in 2004 to 10.3% in 2015 and was associated with significantly higher in‐hospital major adverse cardiovascular and cerebrovascular events (MACCE; OR 5.36) and mortality (OR 2.84) compared to PCI in patients with prior CABG.
Use of arterial conduits and aggressive secondary prevention post‐CABG is key to minimizing need for repeat revascularization procedures.
Post‐CABG patients requiring repeat revascularization procedures may benefit from a HEART team discussion given their elevated procedural risk profile.

Authors: Musumeci Giuseppe , Colopi Marzia 
Published: September 2021

Key Points
The optimal management approach of left main (LM) and equivalent coronary artery disease (CAD) has been consistently debated over the years.
There are limited data on clinical and anatomic conditions influencing outcomes after elective PCI of LM and multivessel CAD.
The complexity of CAD with the intention of achieving complete revascularization, frailty metrics, as well as patient's informed preference should be adequately considered in order to improve outcome even in high‐risk percutaneous procedures.

Published: September 2021

SummaryService function chaining (SFC) creates a requested orchestration for composition and placement of several service functions. One of the most critical issues for the service function providers is achieving the highest quality of service. We consider the problem of optimal Service Function composition and placement in an SFC‐enabled network with the aim of achieving maximum Quality of Service (QoS). To this end, a method of merging the composition, routing, and placement phases is introduced. A genetic algorithm is designed to find the service chain instance with the maximum QoS using grammar‐based Genetic Algorithm (GA) operators. This grammar is provided to filter invalid service compositions based on the data center, security, and mobile scenarios defined by Internet engineering task force. A chromosome in the proposed genetic algorithm corresponds to a service chain instance that matches the proposed grammar. For routing, strongly connected components (SCCs) are extracted to reduce search time in the network. Consequently, the search space is reduced for requests whose start and end nodes are placed in a SCC. Besides, the Floyd Warshall algorithm is used for routing between consecutive services. According to the results, the proposed method outperformed other methods in terms of the number of responded requests, runtime, and cost.
Gradient descent for quadratic functions using geometric mean and the Kai Fang method
Authors: Rim KwangCheol , Kim Pankoo , Ko Hoon 
Published: September 2021

SummaryThe geometric mean is typically used to measure the mean of inflation rate and population fluctuation. It is also used in the description and analysis of singularities and geometric distance spaces. Gradient descent is an integral part of artificial intelligence. In this study, we transform the gradient calculation from conventional quadratic gradient descent algorithms into a root extraction calculation using geometric means. To eliminate the computational complexity of differential operations in gradient calculation and to easily calculate roots using only fundamental arithmetic operations, we introduce the Kai Fang method, the East Asian traditional root extraction method. To do this, we propose a new quadratic gradient descent method based on geometric means and we apply the Kai Fang method with geometric means to create an improved quadratic gradient descent method. The proposed method shows improved computational ease over conventional methods.
Contrasting Effect of Side‐Chain Placement on Photovoltaic Performance of Binary and Ternary Blend Organic Solar Cells in Benzodithiophene‐Thiazolothiazole Polymers

Published: September 2021

Abstractπ‐Conjugated polymers are important materials for organic photovoltaics. While search for new backbone systems is central to the development of π‐conjugated polymers, side‐chain engineering is also imperative. Here, two benzodithiophene‐thiazolothiazole copolymers, PSTz1 and POTz1, were synthesized, for which the side‐chain placement was different. Due to less steric hindrance between the side chains, PSTz1 had a more coplanar backbone than POTz1. This led to significant differences in trend of the performance for the binary and ternary blend cells that used a fullerene (PC71BM) and/or non‐fullerene (ITIC) as the acceptor materials. Whereas PSTz1 showed higher photovoltaic performance in the PC71BM‐based cell, POTz1 showed higher performance in the ITIC‐based cell. Furthermore, in the ternary blend cell, whereas increase in the PC71BM content improved the photovoltaic performance for the PSTz1 system, it was detrimental to the performance for the POTz1 system. These results could be a good guideline for maximizing the performance of organic photovoltaics.

Published: September 2021

AbstractAlthough bee visitation rate to flowers is often used to assess both pollination services and bee abundance, the abundance of social species needs to be assessed by quantifying the number colonies instead of the number of foraging individuals. Because accurately quantifying the number of wild bee colonies can be difficult, the relationship of visitation rates provided by foragers and the abundance of colonies contributing those foragers from the surrounding landscape is poorly documented for social species. Here, we use genetic methods and statistical inference to estimate the abundance of wild colonies of Bombus impatiens in the surrounding landscape providing foragers to 30 commercial pumpkin (Cucurbita pepo) fields over 4 yr across a 13,000‐km2 area in Pennsylvania, USA. We show that the abundance of wild colonies in the surrounding landscape providing foragers per field (colony abundance per field) ranges from 291 to 829 colonies per field. Furthermore, colony abundance per field has been stable across years, counties, and field size, resulting in a dilution of foragers from the available colonies across larger fields. Wild colony abundance, when scaled by field size, by expressing colony abundance on a per hectare basis, is predictive of visitation rate. Thus, we document the relationship of wild colony abundance per hectare to visitation rate at a level that provides sufficient pollination to a highly pollinator‐dependent crop. As expected, genetic differentiation among sampled populations is essentially non‐existent across different fields or regions, suggesting a panmictic population. Although many Bombus species are in decline, we document abundant and genetically resilient wild populations of B. impatiens associated with a mass‐flowering crop under current agricultural practices and provide baseline information needed to monitor these wild populations at a time when they face similar stressors implicated in the decline of congenerics.

Published: September 2021

AbstractThe 3D exoscope is a surgical visualization and magnification tool that has been recently introduced in microvascular anastomoses. However, other surgical scenarios, such as transoral surgery which has a limited surgical field visualization, may benefit from this technology as well. The 3D exoscope was used to perform the transoral excision of a tumor of the soft palate, the free flap harvesting and its insetting to reconstruct the intraoral defect, and perform the microvascular anastomosis. The 3D exoscope provided excellent visualization of the surgical field which greatly contributed to optimal surgical precision of each step involved in the excision and reconstruction. In addition, this technology enabled the surgeons to maintain ergonomic posture and gave the residents and students the chance to carefully follow and learn the surgical procedure step by step. This advanced technology has proven to benefit each phase of transoral demolition and reconstruction.

AbstractObjectiveTo evaluate fetal lung development using pulmonary artery Doppler in pregnant women who had recovered from COVID‐19.MethodsThe prospective case–control study included 41 pregnant women who had recovered from COVID‐19 and 43 healthy pregnant women (control group). All the women in the study group had been diagnosed with COVID‐19 and had completed a quarantine period.ResultsThe demographic data of patients were similar in the groups (P > 0.05). Main pulmonary artery peak systolic velocity was higher and pulsatility indices were lower in pregnant women who recovered from COVID‐19 compared to the controls (P < 0.001, P = 0.001). Acceleration time, ejection time, and acceleration/ejection time ratio (PATET) of the fetal MPA Doppler were significantly decreased in pregnant women who recovered from COVID‐19 (P < 0.001, P = 0.036, and P = 0.002, respectively). The patients who had recovered from COVID‐19 were divided into two groups: those treated with expectant management and those treated in hospital. The pulmonary artery acceleration time and PATET ratio were significantly lower in the group treated in the hospital (P = 0.023 and P = 0.045, respectively).ConclusionDetailed Doppler evaluations of the pulmonary artery may help in evaluating the fetal adverse effects of COVID‐19 disease.
Accurately calibrated frequency domain diffuse optical spectroscopy compared against chemical analysis of porcine adipose tissue
Authors: Lam Jesse H. , Tu Kelsey J. , Kim Sehwan 
Published: September 2021

AbstractFrequency domain diffuse optical spectroscopy (fdDOS) is a noninvasive technique to estimate tissue composition and hemodynamics. While fdDOS has been established as a valuable modality for clinical research, comparison of fdDOS with direct chemical analysis (CA) methods has yet to be reported. To compare the two approaches, we propose a procedure to confirm accurate calibration by use of liquid emulsion and solid silicone phantoms. Tissue fat (FAT) and water (H2O) content of two ex vivo porcine tissue samples were optically measured by fdDOS and compared to CA values. We show an average H2O error (fdDOS minus CA) and SD of 1.9 ± 0.2% and −0.9 ± 0.2% for the two samples. For FAT, we report a mean error of −9.3 ± 1.3% and 0.8 ± 1.3%. We also measured various body sites of a healthy human subject using fdDOS with results suggesting that accurate calibration may improve device sensitivity.

AbstractBackgroundDyslipidemia in diabetes is common and characterized by hypertriglyceridemia with decreased levels of high‐density lipoprotein. The objective of this study was to assess the prevalence of MTHFR C677T polymorphism in Palestinian T2DM patients and to investigate the association between this polymorphism and lipid profile in diabetic patients with and without dyslipidemia.MethodsA total of 208 T2DM patients including 98 with dyslipidemia and 110 without dyslipidemia were enrolled in this study. The MTHFR C677T genotyping was conducted by PCR‐RFLP followed by agarose gel electrophoresis.ResultsThere were no significant differences in either the genotype distribution or allele frequency in T2DM patients with or without dyslipidemia (37.8% CC, 54% CT, 8.2% TT vs. 48.2% CC, 41.8% CT, 11% TT; p = 0.209). However, among the dyslipidemic group, the TT carriers have a higher HDL level (46.8 ± 17.8) compared to (CC+CT) carriers (34.68 + 11.9) (p = 0.01). In the group without dyslipidemia, there was a significant elevation in diastolic blood pressure (DBP) among the CC carriers (83.6 ± 10.6) compared to those who carried at least one mutant allele (CT+TT) (78.1 ± 11.1) (p = 0.009).ConclusionsThe study shows that in our Palestinian population the MTHFR 677TT genotype lowers DBP significantly in patients without dyslipidemia and is related to increased level of HDL in diabetic dyslipidemia patients.
