Published: November 2022

The West-Palearctic region is a diversity hotspot for the ant genus Aphaenogaster. Species in this region are characterized by high morphological variation, which has led to their subdivisioninto different infrageneric groups. The very first classification in three subgenera, dated 1915, was gradually replaced by eight species-groups. To probe the evolutionary consistency of these species-groups, we sequenced 46 species from all eight species-groups and biogeographic sectors of the region, using one mitochondrial (COI) and six nuclear markers (EPICs), and interpreted the results by integrating qualitative morphology. Our results demonstrate the non-monophyly of all formerly recognized subgenera and species-groups, except for the crocea group. We use the phylogeny and morphological characters to propose a new classification of six monophyletic species-groups (crocea, gibbosa, graeca, pallida, sardoa, subterranea). The pallida, subterranea and sardoa (formerly testaceopilosa) groups attain monophyletic status by reassigning a few taxa. The gibbosa group is to be considered exclusively Western-Mediterranean until further assessments of similar Eastern species. The new graeca group is established by including former members of the splendida and subterranea groups, while the polyphyletic cecconii, obsidiana, and splendida groups are dismissed. Notably, the first is not part of the tropical Deromyrma clade as previously thought, while at least two independent clades which require further investigation are composed of species from both the cecconii and splendida groups, suggesting repeated morphological convergences based on similar ecological adaptations. Finally, A. cardenai is confirmed to be a significantly divergent lineage. In addition, three Aphaenogaster species are moved to different genera: Messor asmaae (Sharaf, 2018) comb. nov., Messor isekram (Bernard, 1977) comb. nov., and Pheidole sarae (Sharaf, 2018) comb. nov. Further studies should address the evolutionary relationships between the clades recovered in this study.
Feature Selection Using Neighborhood based Entropy
Authors: Farnaghi-Zadeh Fatemeh , Rahmani Mohsen , Amiri Maryam
Published: November 2022

Feature selection plays an important role as a preprocessing step for pattern recognition and machine learning. The goal of feature selection is to determine an optimal subset of relevant features out of a large number of features. The neighborhood discrimination index (NDI) is one of the newest and the most efficient measures to determine distinguishing ability of a feature subset. NDI is computed based on a neighborhood radius (E). Due to the significant impact of E on NDI, selecting an appropriate value of E for each data set might be challenging and very time-consuming. This paper proposes a new approach based on targEt PointS To computE neIgh- borhood relatioNs (EPSTEIN). At first, all the data points are sorted in the descending order of their density. Then, the highest density data points are selected as many as the number of classes. To determine the neighborhood relations, the circles centered on the target points are drawn and the points inside or on the circles are considered to be neighbors. In the next step, the significance of each feature is computed and a greedy algorithm selects appropriate features. The performance of the proposed approach is compared to both the commonest and newest methods of feature selection. The experimental results show that EPSTEIN could select more efficient subsets of features and improve the prediction accuracy of classifiers in comparison to the other state-of-the-art methods such as Correlation-based Feature Selection (CFS), Fast Correlation-Based Filter (FCBF), Heuris- tic Algorithm Based on Neighborhood Discrimination Index (HANDI), Ranking Based Feature Inclusion for Optimal Feature Subset (KNFI), Ranking Based Feature Elimination (KNFE) and Principal Component Analysis and Information Gain (PCA-IG).

Published: November 2022

One of the greatest challenges for older, homebound patients receiving health care is accessibility, particularly following a hospitalization. The current study evaluates the effects of using voice-activated technology in the homes of recently discharged patients and its effects on health care outcomes. Voice-based software was embedded in a smart device, which allowed patients to ask questions and receive answers about their own specific care plan. A pre-post study design was used. Forty-eight patients completed the pre and post survey. There was a 63% reduction in emergency department visits and a 26% reduction in physician calls. There was no change in the number of patients requiring hospitalization. More than one half of patients used the smart device daily for their health care needs. More than 70% of patients believed the device was helpful for their general health care needs and assisted in the achievement of care goals. This is the first study of its kind to evaluate patient engagement and outcomes after the use of a smart device with embedded health care directions. [

Effect of the COVID-19 Lockdown on Myopia Progression of School-aged Children: A Retrospective Chart Review
Authors: Hadi Dalia El , Moukhadder Hassan M. , Mansour Hana , Wehbi Zahi , Ghannam Alaa Bou , Al-Haddad Christiane
Published: November 2022

Purpose:

To study the effect of the coronavirus disease 2019 (COVID-19)–related lockdown on myopia progression of school-aged children, comparing across the years and within different age groups.

Methods:

This was a retrospective chart review of school-aged children with myopia who presented to the pediatric ophthalmology clinic at the American University of Beirut between January 2020 and December 2021 (during COVID-19 lockdown). Annual myopia progression rate (back to January 2016) was computed by dividing the absolute value of the spherical equivalent (SE) difference of two consecutive visits by the duration (in years). Demographic data were retrieved. Patients were then divided into three age groups (3 to 10, 11 to 14, and 15 to 18 years) for analysis.

Results:

A total of 443 charts of myopic school-aged children were reviewed. Their average age was 11.81 ± 3.67 years with an average of 3.85 ± 1.67 visits across the years. The mean myopic SE increased over time: SE in 2021 was significantly higher than the mean SE in 2016, 2017, 2018, and 2019. Mean SE in 2020 was significantly higher than that in 2016 and 2017. There was no statistically significant difference in the mean annual progression (in diopters/year). For the 3 to 10 years group, the annual SE progression tended to be highest for 2020–2021 and 2019–2020 compared to previous years.

Conclusions:

Children had more myopia in 2021 and 2020 (during lockdown) compared to previous years. The myopia annual progression tended to be highest in 2020–2021, especially for the younger age group, but the difference was not statistically significant.

Published: November 2022

Purpose:

To investigate the correlation between demodicosis and pediatric chalazia.

Methods:

A case-control prospective study was conducted at Children's Hospital of Fudan University between December 2018 and January 2019. One hundred one consecutive pediatric patients with chalazia and 42 pediatric patients without chalazia underwent eyelash sampling and
Demodex
examination using light microscopy, and mite presence and count were documented.

Results:

The
Demodex
count and prevalence of the chalazia group was much higher than that of the control group (3.06 ± 3.48 vs 0.64 ± 1.17;
P
≤ .001; 73.3% vs 35.7%,
P
≤ .001). The
Demodex
count and prevalence of the multiple chalazia subgroup was much higher than that of the single chalazion subgroup (3.49 ± 3.72 vs 2.00 ± 2.52;
P
= .043; 79.2% vs 58.6%,
P
= .035). The
Demodex
count and prevalence of the chalazia with skin erosion subgroup was much higher than that of the without skin erosion subgroup (3.54 ± 3.14 vs 2.55 ± 3.76;
P
= .012; 82.7% vs 63.3%,
P
= .027). After adjustment for age and gender,
Demodex
count (odds ratio: 1.873; 95% confidence interval: 1.155 to 3.040;
P
= .011) but not presence (
P
= .643) was significantly correlated with chalazia.

Conclusions:

Demodex
mites were more prevalent and quantitative in children with chalazia, and children with severe chalazia had higher
Demodex
prevalence and quantity. High
Demodex
count rather than presence of it was associated with chalazia.

Neural architecture search based on dual attention mechanism for image classification
Authors: Jin Cong , Huang Jinjie , Wei Tianshu , Chen Yuanjian
Published: November 2022

Deep learning neural networks based on the manual design for image classification tasks usually require a large amount of a priori knowledge and experience from experts; thus, research on designing neural network architectures automatically has been widely performed. The neural architecture search (NAS) method based on the differentiable architecture search (DARTS) ignores the interrelationships within the searched network architecture cells. The optional operations in the architecture search space lack diversity, and the large parametric and non-parametric operations in the search space make the search process inefficient. We propose a NAS method based on a dual attention mechanism (DAM-DARTS). An improved attention mechanism module is introduced to the cell of the network architecture to deepen the interrelationships between the important layers within the architecture by enhancing the attention between them, which improves the accuracy of the architecture and reduces the architecture search time. We also propose a more efficient architecture search space by adding attention operations to increase the complex diversity of the searched network architectures and reduce the computational cost consumed in the search process by reducing non-parametric operations. Based on this, we further analyze the impact of changing some operations in the architecture search space on the accuracy of the architectures. Through extensive experiments on several open datasets, we demonstrate the effectiveness of the proposed search strategy, which is highly competitive with other existing neural network architecture search methods.

Authors: Mehmood Yasir , Shahid Hira , Tariq Aysha , Ali Syeda Omama
Published: November 2022

Common inflammatory airway disorders, such as seasonal and perennial allergic rhinitis, acute sinusitis, and nasal polyposis, can have a significant impact on patient health and quality of life. Intranasal corticosteroids are recommended as part of treatment plans for each of these illnesses because they reduce inflammation and thus symptoms. In order to compare the efficacy and safety of a new nano formulation of mometasone furoate nano-nasal spray (MF-NNS) with a commercially available nasal spray called mometasone furoate nasal spray (MFNS) for the treatment of allergic rhinitis, 20 rhinitis patients were enrolled in this randomized controlled trial (10 to 50 years). Patients were given 50 mcg MF-NNS doses in the morning and evening. This regimen was administered as a nasal spray for a 3-week efficacy and safety phase. The primary endpoints changed from baseline in the subjects’ congestion as determined by the physicians’ assessment of allergic rhinitis. Analysis of variance was used to evaluate all efficacy end points. More clinical trials have shown that MF-NNS reduces both objective and subjective markers of inflammation in adults, adolescents, and children.

Представлены результаты теоретических исследований механизма разрушения теплозащитных композиционных материалов. Исследованы процессы, вызванные взаимодействием атомов и молекул кислорода с диоксидом кремния и материалами на основе диоксида кремния с учетом химических процессов в промежуточном слое между газом и поверхностью композиционного материала в разреженных средах. Показано, что механизм разрушения зависит от каталитической активности, контролирующей динамику различных физико-химических процессов с участием О и О$_2$ на поверхности. Получены результирующие характеристики разрушения стеклообразных материалов, которые являются итогом действия двух в известной мере взаимно противоположных процессов. Проведен анализ основных закономерностей разрушения стеклообразных материалов. Показано, что скорость рекомбинации существенно зависит от энтальпии торможения газового потока. Результаты численных расчетов показывают, что процесс неравновесного уноса массы может быть рассчитан инженерными методами.

Authors: Admiraal Wilfried
Published: November 2022

In view of the teacher shortage in the Netherlands and Flanders, it is not only important to increase the intake and outflow of students in teacher education programmes, but also to increase job satisfaction of in-service teachers. Satisfied teachers in school will lead to higher retention of teachers in the profession. Based on secondary analyses of TALIS 2018 data from primary and secondary school teachers in the Netherlands and Flanders, work and school conditions and their job satisfaction have been examined. Regression analyses show that feelings of distress, perceived stress in teaching and classroom management and perceived barriers to professional development show a negative relationship with job satisfaction. Moreover, a safe learning and working climate in school and school satisfaction in general are positively related to teachers’ job satisfaction. The results are discussed in the light of findings from other research on teachers’ job satisfaction and research of TALIS data, in particular.

Esto genera un desequilibro en HA y AF debido a que no lograr utilizar la energía del contenido calórico que consumen. La frecuencia de AF de un individuo está influenciado, por ejemplo, en el nivel local o micro por la densidad de tráfico en su zona de residencia, por la disponibilidad de espacio para realizar actividad física (zonas verdes, pistas de jogging, parques infantiles, parques de patinaje, halfpipes, etc.) o por la presencia de límites de velocidad, sombra, aceras y bicicletas caminos. Los alimentos disponibles en los puntos de venta regionales (incluidos mercados semanales, restaurantes y la industria del servicio de alimentos), es relevante para los hábitos alimenticios de las personas. El objetivo fue examinar la correlación entre las variables de estudio ambiente físico del individuo y hábitos saludables en alimentación y AF. Dentro de los principales resultados se encontró que existe una correlación débil .341** entre la percepción del ambiente físico y la AF lo que concuerda con algunos estudios. Además se encontró una relación débil entre el ambiente físico y los hábitos de alimentación con una puntuación de .149* lo cual concuerda con los antecedentes.

For most of the universities worldwide, online learning was one of the efforts to minimize the spread of Covid-19. However, today, almost two years after this dramatic experience in all aspects of living, working and learning/studying, as the global trend in online learning remains upward. Although some higher education institutions worldwide were shifting in the direction of online content delivery and online learning and before Covid-19, the pandemic both accelerated and forced a more universal move in this direction especially in developing countries. In the country, the online learning was implemented without planned prior preparation. Our educational system faced a state of emergency caused by the pandemic. As such, the experience and lessons learned from this forced adoption of online learning in the country is exceptionally valuable as basis for further improvement and leveraging the potential of online learning. The goal of this paper is to investigate the determinants of students’ behavior in relation to the use of online learning in higher education in the country, on the sample of the Faculty of Economics, Ss. Cyril and Methodius University in Skopje. The basis for the research model in this study is the original Unified Theory of Acceptance and Use of Technology - UTAUT model. This fundamental model examines the crucial predictors/factors of technology adoption like: performance expectancy, effort expectancy, social influence, facilitating conditions, behavioral intention and usage behavior (acceptance). For the purpose of this research, the basic UTAUT model is extended by additional construct - perceived enjoyment recognized as important factor regarding young population technology adoption. Data were collected from more than 120 undergraduates during April and May 2022, while online learning was still undergoing. This research provides relevant theoretical and practical implications by elaborating that the analyzed factors are critical in students’ behavior in relation to the use of online learning in our country context.
The Omicron-transformer: Rise of the subvariants in the age of vaccines
Authors: Chia Travis Ren Teen , Young Barnaby Edward , Chia Po Ying
Published: November 2022

Introduction: Omicron is the latest SARS-CoV-2 variant of concern, the pathogen that causes COVID-19. Since its emergence in late 2021, Omicron has displaced other circulating variants and caused successive waves of infection worldwide throughout 2022. Omicron is characterised by the rapid emergence of many subvariants and high rates of infection in people with vaccine- and/or infection-induced immunity. This review article will consolidate current knowledge regarding Omicron subvariants, the role of boosters, and future vaccine development. Method: This narrative review is based on a literature search using PubMed. Search terms related to Omicron were used and priority was given to published peer-reviewed articles over pre-prints. Results: Studies indicate that vaccinations and boosters are important to reduce disease severity, hospitalisation and death from Omicron. A variety of factors, such as differing host factors, circulating variants, and forces of infection, can influence the benefit of repeated booster administration. Next-generation bivalent vaccines have now been approved in some countries including Singapore and have demonstrated the ability to induce broad variant protection. Future third-generation vaccines involving mucosal vaccines and/or pan-sarbecovirus vaccines may provide broader and longer-lasting protection. Conclusion: Due to current high levels of vaccine- and infection-induced immunity, it is likely that rates of severe illness, hospitalisation, and death due to Omicron will continue to moderate. Nevertheless, the virus is ever-changing, and public health policies, especially those related to vaccinations, will also have to continually evolve and adapt as COVID-19 transitions to endemicity.

Velella velella (Hydrozoa) on the coast of Pakistan along the northern Arabian Sea
Authors: Gul S.
Published: November 2022

Taxonomic information on Hydrozoa from waters of Pakistan is limited to relatively few studies. None of them reported the pleustonic species Velella velella (Linnaeus, 1758). Daniel (1976) reviewed the worldwide distribution of the two dimorphic forms of V. Velella (with the sail oriented either Northwest or Southeast), but no occurrences of the species were recorded in the northern Arabian Sea. The aim of this report is to record this hydrozoan found on the coast of Pakistan, as knowledge of its occurrence in the region is lacking in the scientific literature.

Published: November 2022

The five-striped palm squirrel, Funambulus pennantii and three-striped palm squirrel, F. palmarum, consume liquid food in the form of nectar and latex in addition to solid food. The latexy secretion from the abaxial surface of the leaves at the junction of petiole and lamina of the leaves of the Banyan, Ficus benghalensis (Moraceae) is licked by both F. pennantii and F. palmarum as food. A scar is seen on the licked site of every leaf which appears to be a result of repeated licking and drying of the residue of the secretion.
