Published: December 2022

Abstract
The application of a graph convolutional network (GCN) to collaborative filtering (CF) is a new direction of recommendation system and has achieved good results. However, the problem of data uniformity, that is, the quality of embedded expression of different data after multiple convolutions, still persists. In this paper, we propose a convolution method using dense connection, which can effectively reduce data uniformity and improve the performance of the recommended model. This dense connection embedding calculation method can maximize the influence of low-order embedding on high-order embedding, thereby improving the uniformity of higher-order embedding. At the same time, the noise problem also affects the quality of embedded expression. We introduce contrastive learning into graph CF to alleviate the noise problem. Contrastive learning optimizes contrastive loss by reducing the distance between positive samples and increasing the distance between negative samples. We use a contrastive learning method through graph perturbation. Specifically, we randomly lose the edges of the graph twice to make contrastive learning between two graphs. At the same time, we also compare different nodes of each subgraph. This contrastive learning method improves the performance of the recommendation model. Experiments show that our model has significantly improved on multiple open datasets. Compared with the baseline, our model has 14% and 31% performance improvements on yelp2018 and book-crossing datasets, respectively, proving that our changes are effective and interpretable.

Published: December 2022

Abstract
Herein, we have reported synthesis, characterization and catalytic activity of an efficient and reusable silica-based catalyst MCM@CP@PAL@Cu. This catalyst was prepared by the anchoring of Cu(II)-Schiff base complex on mesoporous MCM-41 grafted with -chloro group on the surface. The obtained catalyst was characterized with various analytical methods such as FT-IR, low angle P-XRD, TGA, N2 adsorption-desorption, SEM, TEM and MPAES. The catalyst composition and chemical state of Cu metal identified using X-ray photoelectron spectroscopy. The catalyst MCM@CP@PAL@Cu employed for the conversion of various alkenes to their epoxides using tert-butyl-hydroperoxide (TBHP) oxidant and acetonitrile as a solvent. 99% yield of the epoxide obtained with model reaction and catalyst can be reused minimum six times with same efficiencies.
Pseudo-Carleson measures and generalized Ces`aro-like operators
Authors: Zhou Zhihui 
Published: December 2022

Abstract
Let $\mathbb{D}$ be the open unit disk in the complex plane and $H(\mathbb{D})$ the space of functions analytic in $\mathbb{D}$. Suppose that $f(z)=\sum_{n=0}^{\infty}a_n z^n$ is an analytic function in $\mathbb{D}$ and $s>0$. The generalized Ces\`aro-like operator is defined by$$ \mathcal{C}_{\mu,s}(f)(z)=\sum_{n=0}^{\infty}\big(\int_{\mathbb{D}}w^{n}d\mu(w)\sum_{k=0}^{n}\frac{\Gamma(n-k+s)}{\Gamma(s)(n-k)!}a_{k}\big)z^n,$$ where $\mu$ is a finite positive Borel measure on the unit disk $\mathbb{D}$. We remark here that the operators have been widely studied for the case $s=1$ and the measure $\mu$ is support on the interval $[0,1)$. We also introduce some pseudo-Carleson measures which are needed in studying generalized Ces\`aro-like operators. In this paper, we study some properties of pseudo-Carleson measures and determine the range of the Ces\`aro-like operator acting on the space of all bounded analytic functions.

Abstract
Background
Autism spectrum disorder (ASD) is a neurodevelopmental disability associated with deficiency in social interaction, unusual development of social communication, and restricted or repetitive behaviors, interests and activities. This study aimed to describe management of pediatric ASD in Cameroon, a resource-constrained Central Africa country.
Methods
A cross-sectional study was conducted between December 2021 and May 2022 at Pediatrics department of a reference hospital in the town of Douala. Data of interest of children with ASD were collected through medical records and telephone discussion with their parents.
Results
A total of 145 children with ASD aged 2–15 years were included, giving a hospital prevalence of 3.7%. Time delay between parental concerns and hospital management was specified in 69 (47.58%) children among them 38 (55.07%) the mean delay ± SD was less than five months. Children were mainly males (76%) and aged 4–5 years (37.93%), with mean age ± SD of 44.4 ± 22.2 years old. The main consultation reason was language delay or absence (100%). Mean time delay between parental concerns and the first medical consultation was 18 months (range 1–60 month). Comorbidities were greatly represented by attention deficit hyperactivity disorder (42.45%). Neuropsychology (66.2%) was the most frequently used intervention. Some children were treated using traditional medicine.
Conclusions
Management of pediatric ASD is strongly influenced by socioeconomic and cultural context. It is crucial to implement behavioral change campaigns in community, organize training sessions to medical staff on diagnosis and treatment of ASD, and provide specialized centers with skilled staff and equipped material.

Trends of Maternal Deaths in a Tertiary Care Hospital of Southern India
in the Pre-COVID-19 Era: A 10-Year Retrospective Study
Authors: Paladugu Sanghamitra , Srinivas Sujatha Bagepalli , Mundkur Anjali Suneel 
Published: December 2022

Background:
The current United Nations sustainable development goal 3 sets to reduce
maternal mortality to less than 70 per 100 000 live births by 2030. To monitor whether India is on
track to attaining sustainable development goals, it is essential to routinely assess trends of health
indicators.

Objectives:
This study was conducted to assess trends of maternal mortality and cause-specific
maternal death in tertiary care hospitals in Southern India.

Methods:
This is a retrospective study of hospital records and death summaries of all maternal deaths
between January 1, 2009, and December 31, 2018, at the tertiary care hospital in Southern India. The
demographic, clinical, and delivery details of all the maternal deaths were collected. Causes of maternal
deaths were classified as direct, indirect, and nonspecific. To observe trends of maternal death, the
maternal mortality ratio was calculated for each year, and Pearson’s chi-square test was used.

Results:
Maternal mortality ratio was 555/100000 and had a decreasing trend from its highest in 2010
of 1230/100000 to its lowest of 229/100000 in 2017 (t = 7.71 p = 0.02). The majority of women who
died were aged 21-35 years, resided in rural, were primigravidae, and had operative delivery. Most of
the maternal deaths had been referred to our facility (90.8%) from other healthcare units. Obstetric
hemorrhage (27.8%) and puerperal sepsis (37.7%) among direct causes; H1N1 pneumonia (34.8%)
among indirect causes were the major causes of maternal death. The number of maternal deaths due to
sepsis increased from the beginning until the end of the study from 10% to 50% (t = 5.9, p = 0.01). On
the contrary, there was a decline in maternal deaths due to obstetric hemorrhage from 50% to 25% (t =
4.2, p = 0.03).

Conclusion:
Although the maternal mortality ratio has reduced over the years, sepsis was an
important cause of maternal deaths.

Synthesis and Morphology Towards Various Oxidizing and Reducing
Gases
Authors: Shaikh Tarannum , Jain Shilpa 
Published: December 2022

Abstract:
Nanotechnology has enabled sensors to detect and sense a very small amount of chemical
vapors. Sensors play a major role in our daily life. The use of sensors has made human life easy. One
such type of sensor is the Gas sensor made up of Semiconducting metal oxides. These sensors have
their own unique features which help in the easy monitoring of toxic gases. Out of all the metal oxide
present, the gas sensors made up of ZnO nanostructures are mostly used in the gas sensing industry.
ZnO has become a research hotspot of gas-sensing material because of the variation in resistance observed
on the surface. These resistance changes are observed due to the adsorption & desorption of
gases. In this review, we will be discussing the ZnO nanostructures, their preparation and their applications
in the sensing of various toxic and flammable gases.

Published: December 2022

Cocoa powder comes with various attributes in its taste affecting consumer acceptance. The analytical hierarchy process (AHP) approach can be used to identify the effect of each attribute on the sensory profile of cocoa powder. This present study used the AHP approach to determine the degree of importance of sensory attributes on several types of cocoa powder and find the type with the best sensory profile. Cocoa powder comes from cocoa beans made through fermentation and non-fermentation process. In addition, we used non-fermented cocoa powder treated with water and incubated at 45oC for 4, 8, and 16 hours later named as incubated cocoa powder. Then, the sensory attributes of fermented cocoa powder were used as the reference in assessing the sensory profile of incubated cocoa powder, including the one going through the treatment. The sensory analysis performed by trained panelists revealed 11 attributes that made up the flavor profile of cocoa powder. Of these 11 attributes, only 4 were considered primary attributes with a high degree of importance, including chocolate (23.7%), sweet (19.9%), caramel (11.8%), and nutty (10.9%). Other attributes had a lower degree of importance, including creamy (7.4%), fruity (6.5%), green (5.4%), flowery (4.8%), astringent (4.5%), bitter (3.1%), and acid (2.2%). AHP also ranked the incubated cocoa powder based on the similarity of the flavor profile with fermented cocoa powder. Nonfermented cocoa powder without treatments fell into the lowest rank, while nonfermented cocoa powder with treatments fell into a higher category in the following order: 8 hours > 16 hours > 4 hours. To summarize, AHP can be used in decisionmaking affected by many factors. AHP has been proven effective in determining the sensory profile of cocoa powder, especially in choosing the attribute withthe highest effect. In addition, AHP helps determine the best treatment for incubated cocoa powder to produce the most similar sensory profile to fermented cocoa powder.

Published: December 2022

The issue of cadmium in cocoa beans has become one of the primary considerations in setting quality criteria in chocolate-consuming countries. Using rootstock genotypes that are tolerant to cadmium uptake can provide data on the absorption of cadmium into shoots for recovery. This study examined cocoa plants’ growth and physiological response to cadmium (Cd) accumulation. The research was carried out using polybags in the Greenhouse of the Indonesian Coffee and Cocoa Research Center using a half-sib family of cocoa aged 4 months after sowing. The study was designed using a completely randomized split-plot design with 3 replications. The parent plots were the half-sib families of Sulawesi 1, Sulawesi 2, and Scavina 6. The subplots were added with cadmium solution at 0 (control), 2, 4, and 8 ppm. The results showed that adding cadmium up to 8 ppm did not affect the growth and biomass of cocoa seedlings; however, it had a negative effect on plant physiological processes of the net assimilation rate and relative growth rate. Cadmium content in the tissue increased with increasing cadmium concentration in the growing medium. The accumulation of cadmium in roots was higher than that of shoots. Absorption of cadmium in the root tissue of Sulawesi 1 was higher than that of Scavina 6 and Sulawesi 2; genetic factors did not affect cadmium uptake in the shoots. There was a positive correlation between root dry weight and cadmium concentration in the tissue; the higher the dry weight of the root tissue, the higher the cadmium uptake in plants.

Nosso cotidiano é cada vez mais permeado por soluções autônomas e inteligentes baseadas em coleta de dados e Inteligência Artificial. E já se observa seus benefícios de tempo, custo e escala. Mas quais suas possíveis implicações num campo complexo como a Educação? A chamada Edtech, através de tecnologias como os Sistemas de Tutoria Inteligente a Plataformas Adaptativas, evolui para se tornar capaz de registrar, avaliar e prever o comportamento cognitivo e emocional dos alunos e, com isso, fornecer respostas e trilhas de aprendizagem personalizadas com pouca ou nenhuma participação humana. Muitos autores problematizam esse cenário, apontando dúvidas e incongruências em, por exemplo, se tratar o processo subjetivo de formação do ser humano de uma forma essencialmente matemática, objetiva. Levando em conta a importância fundamental da Educação para a sociedade, este artigo propõe uma discussão (auto) crítica e duas perguntas: numa visão centrada no ser humano, quais as implicações para profissionais de UX, Ergonomia e Design ao projetar e avaliar esses sistemas e soluções? E sendo a Educação autônoma e preditiva tão complexa e delicada, essas pessoas não deveriam lidar com ela através de abordagens mais sistêmicas e contínuas?
