Facial beauty prediction (FBP) is a rising topic in the area of evaluating attractiveness, with the goal of making assessments which are more human-like. Since FBP is a regression problem, there are many data driven ways to determine the relationships among face traits and beauty ratings. Deep learning approaches have shown their incredible potential for feature representations and analysis of the data. Convolutional Neural Network (CNN) has demonstrated extremely outstanding performance in facial identification and understandings, and have been proven to be an effective way for exploring facial features. Recently, a lot of well-designed networks with efficient topologies have been researched for improved representation of ability. However, these models focus more on the efficient block but do not create an efficient data transmission route, resulting in a feature representation capacity which is sub-optimal. In this paper, we have taken the Alex Net model into consideration which is a deep convolutional network which has been created to consider a large range of colorful images (224x224x3). It has a range of 62 million parameters which are trainable. For better performance, an intricate network architecture for the FBP issue is given in this research.
Will Mexico meet its climate commitments?

Published: May 2023

In its Nationally Determined Contribution (NDC), Mexico is committed to reducing unconditionally 22 and 51% of its emissions of greenhouse gases (GHGs) and black carbon, respectively, by 2030, with an emission peak in 2026. Additional reductions of 36 and 70%, respectively, are proposed conditioned to support from other parties. In this work, the percentage of reduction to reach the emission mitigation targets that Mexico proposed in its NDC is estimated. The results show that in order to meet its unconditional NDC, Mexico should start mitigation in 2020 with a 1.5% reduction rate until 2030 and a 3.3% reduction rate by 2050, to reach an emission peak in 2023. To meet the conditional NDC, a 3.1% emission reduction rate until 2030 should be applied, with peak emission in 2021, and 5.8% from 2030 to 2050. In none of these estimates an emission peak in 2026 matches the NDC mitigation options. Furthermore, none of the emissions reduction pathways estimated in this study fulfills the conditional or unconditional contribution and peaks in 2026 at the same time. Mexico has a long history in international climate policy and is a key emerging economy among the top 15 highest GHG emitters. If Mexico does not achieve its NDC, the international implications, both political and climatic, could put the NDC model at risk if there are more large emitters that do not comply with their contribution.

Los índices de calidad del agua (ICA) son herramientas para comunicar la calidad del agua a una audiencia no especializada, basándose en los datos del monitoreo de los cuerpos de agua. El objetivo de este proyecto fue determinar el ICA en cinco observatorios participativos (OP) ubicados en el norte de México, además de generar mapas y cuadros que presenten la información de forma concreta y clara sobre la calidad del agua y zonas de riesgo. Utilizando los datos de la Comisión Nacional del Agua se determinó la calidad de agua con los índices de León y del Consejo Canadiense de Ministros de Medio Ambiente, así como la calidad microbiológica con base en los reportes de coliformes fecales. Se clasificaron los sitios de los OP, en cuanto a la calidad microbiológica, de “excelente” a “fuertemente contaminada”. De acuerdo con los límites permisibles por las normas oficiales mexicanas para agua de consumo humano y riego agrícola, se aplicó una escala relativa con un puntaje de 0 a 100, para los índices determinados en los OP. Los resultados indican a través de los mapas desarrollados en el estudio, la presencia de tres sitios fuertemente contaminados microbiológicamente. En lo referente a la calidad requerida para consumo humano, el índice canadiense califica la calidad del agua como “pobre” en todos los sitios estudiados, mientras que el índice de León la clasifica en la escala de “contaminada” a “levemente contaminada”. Ambos índices indican la necesidad imperiosa de un tratamiento antes de ser destinada al uso de consumo humano.

Published: May 2023

In this work, we obtained three new phosphorescent iridium complexes (Ir1-Ir3) of general stoichiometry [Ir(N^C)2(N^N)]Cl decorated with oligo(ethylene glycol) fragments to make them water soluble and biocompatible, as well as to protect them from aggregation with biomolecules such as albumin. The major photophysical characteristics of these phosphorescent complexes are determined by the nature of two cyclometallating ligands (N^C) based on 2-pyridine-benzothiophene, since quantum chemical calculations revealed that the electronic transitions responsible for the excitation and emission are localized mainly at these fragments. However, the use of various diimine ligands (N^N) proved to affect the quantum yield of phosphorescence and allows for changing the complexes sensitivity to oxygen, due to the variations in the steric accessibility of the chromophore center for O2 molecules. It was also found that the N^N ligands made possible to tune the biocompatibility of the resulting compounds. The wavelengths of the Ir1-Ir3 emission maxima fall in the range of 630-650 nm, the quantum yields reach 17% (Ir1) in deaerated solution and sensitivity to molecular oxygen, estimated as ratio of emission lifetime in deaerated and aerated water solution, displays the highest value 8.2 for Ir1. The obtained complexes feature low toxicity, good water solubility and the absence of a significant effect of biological environment components on the parameters of their emission. Of the studied compounds Ir1 and Ir2 have been chosen for in vitro and in vivo biological experiments aimed at estimation of oxygen concentration in cell lines and tumors. These sensors have demonstrated their effectiveness for mapping the distribution of oxygen and for monitoring hypoxia in biological objects studied.

Improved Workflow for Production Modeling in Unconventionals Using Gaussian Mixtures and Principal Components
Authors: Sharma Akash , Sudar Selvendran
Published: May 2023

The current industry-wide practice of generating asset production curves is over-simplified and does not account for a lot of factors. This may lead to reporting errors and challenges in accurately and quickly quantifying well performance and asset potential. The present paper leverages Gaussian Mixture models and principal components to propose a new workflow for production modeling that incorporates all contributory factors while improving accuracy as well as speed.

We began by selecting ~2600 gas wells with at least 2 years of production history. Exploratory data analysis was conducted on the geology, petrophysics, well design and completion characteristics of the wells. Gaussian Mixtures were selected as the clustering model due to their performance and synergies with factor distributions. Singular Vector Decomposition was then used to extract the most predictive Eigenvectors (principal components) for each cluster. Cluster-level production profiles are created from these eigenvectors. Thus, this process leverages the predicting factors as well as heterogeneity in each of the well’s production profiles while creating a representative type curve.

RMSE values were calculated between the cluster-level predicted production profile and the individual well production curves. GMM-based models performed strongly with an RMSE of 0.146 for the training data and 0.746 for the test data. Additionally, type curves were calculated using more traditional means by taking monthly averages over the region as well as on an operator level. These type curves were then compared to the monthly production values for the populations they represent and the RMSE’s were calculated. The regional type curve had an RMSE of 9.3 and the company-level had an RMSE of 5.9, quantifying the marked improvement from our process. The proposed approach simplifies forecasting by providing rapid, reliable production heuristics for early-life wells without the need for complex, models that may need to be built individually from well to well.

The proposed workflow builds upon existing literature on clustering and principal components, to create a novel workflow for reliable and more comprehensive type curve generation. Additionally, it adds to the existing knowledge-based by showcasing how multiple statistical techniques can benefit our modeling work within the industry as well as provide valuable support on early life production forecasting, which is a key challenge.
Game Theory Solution to Buyback Contracts
Authors: Kose Erkan , Canbulut Gulcin
Published: May 2023

Supply chain contracts are important tools for sharing risk and increasing overall supply chain profitability. Research on supply chain contracts shows that supply chain actors can make more profit if they cooperate with other actors instead of acting alone. Game theory has become an important tool in the analysis of supply chains with multiple actors whose primary purpose is to increase their own profits. In cooperative games, players try to get more than they can alone by forming coalitions. In this study, buyback contract, which is one of the most used contract types in order to ensure supply chain coordination, is tried to be handled with the game theory. Considering the similarity of the relations between game theory and supply chain actors, it is aimed to distribute the profits of the supply chain more equitably. In the study the gains that the supply chain actors will gain in case of using buyback contract for different coalition options are calculated. Then, a game theory-based approach was followed to distribute profits fairly among supply chain actors. The results showed that the proposed approach can provide a more equitable profit sharing among supply chain actors. The main contribution of this study to the literature is that the profit sharing between supply chain actors has not been handled with the logic of game theory until this time. Therefore, it is thought that this study will open the door to examining other supply chain contracts within the scope of cooperative games.
Absence of effects of widespread badger culling on tuberculosis in cattle
Authors: Torgerson Paul , Hartnack Sonja , Rasmussen Philip , Lewis Fraser , Langton Thomas
Published: May 2023

Government policy in England aims for the elimination of bovine tuberculosis (bTB). This policy includes culling of European badger (Meles meles) to reduce cattle TB incidence. The rationale is based on the results of a field trial, the Randomised Badger Culling Trial (RBCT) 1998–2005, which reported a substantial decrease in bTB herd incidence where badger culling had been implemented, in comparison to untreated control areas. The results were reported in 2006 in the journal Nature. Recent analysis of proactive badger culling in England since 2013 has raised concerns that badger culling, based on RBCT methods, may not reduce bTB herd incidence. The present study re-examined data from the RBCT experiment using a range of statistical models. It concluded that most analytical options did not show any evidence to support an effect of badger culling on herd incidence of bTB ‘confirmed’ by visible lesions or bacterial culture post mortem. However, the statistical model selected and reported from the RBCT study was one of the few models that did show an effect. Various criteria suggest that this was not an optimal model compared to other analytical options then available. The most likely explanation is that the RBCT proactive cull analysis overfitted the data with a non standard method to control for exposure. This resulted in it having a poor predictive value. Fresh appraisals suggest that evidence from more suitable analysis of the original data show that badger culling does not bring about the reported effects. The RBCT found no evidence of an effect on ‘total’ (confirmed and unconfirmed) bTB herd incidence, which we have also found using the more suitable statistical models. The selective choice of use only of ‘confirmed’ incidence data, together with more recent (2013) published perception that RBCT data presented ‘a strong evidence base….with appropriate detailed statistical or other quantitative analysis’ should now be adjusted to conclude that this evidence base is weak or at least, equivocal. The results of the present report are consistent with findings that badger culling in England (2013–2019) shows no significant disease control benefit. The findings of this study help explain one form of driver to the reproducibility crisis, in this case with disease control management in an increasingly intensified livestock industry.
A HIF independent oxygen-sensitive pathway for controlling cholesterol synthesis

Cholesterol biosynthesis is a highly regulated, oxygen-dependent pathway, vital for cell membrane integrity and growth. In fungi, the dependency on oxygen for sterol production has resulted in a shared transcriptional response, resembling prolyl hydroxylation of Hypoxia Inducible Factors (HIFs) in metazoans. Whether an analogous metazoan pathway exists is unknown. Here, we identify Sterol Regulatory Element Binding Protein 2 (SREBP2), the key transcription factor driving sterol production in mammals, as an oxygen-sensitive regulator of cholesterol synthesis. SREBP2 degradation in hypoxia overrides the normal sterol-sensing response, and is HIF independent. We identify MARCHF6, through its NADPH-mediated activation in hypoxia, as the main ubiquitin ligase controlling SREBP2 stability. Hypoxia-mediated degradation of SREBP2 protects cells from statin-induced cell death by forcing cells to rely on exogenous cholesterol uptake, explaining why many solid organ tumours become auxotrophic for cholesterol. Our findings therefore uncover an oxygen-sensitive pathway for governing cholesterol synthesis through regulated SREBP2-dependent protein degradation.

The first of the adult insects was collected from Kömüşini, Kulu, Konya, and the other from Keklikdere, Bingöl, Turkey. According to the results obtained, the female reproductive system in both species consists of a pair of ovaries, lateral oviducts, a common oviduct, spermatheca, bursa copulatrix, and genital chamber. Each ovary has ~ 28 ovarioles in I. speciosus, ~ 50 ovarioles in M. cernyi. In both species, each ovariole consists of a terminal filament, germarium, vitellarium, and pedicel. However, the properties (The number of ovaries, presence-absence of terminal filament, thickness, the length of terminal filament, dimensions of germarium, the number of oocytes in vitellarium, ooplasm content of oocytes, the shape of follicle epithelium surrounding oocytes, the size of oocytes, oocyte surface differentiation) of these parts differ according to the species. In both species, previtellogenesis, vitellogenesis, and choriogenesis stages oocytes were found in the vitellarium. In this study, the similarities and differences in the anatomical and histological structures of the parts of the female reproductive system of I. speciosus and M. cernyi with species belonging to other families were compared.

Temperature is an only critical factor which influences insect population dynamics, development and reproduction. Nilaparvata lugens (Stål) is one of the major insect pests of paddy crop in East and Southeast Asia, which significantly reduces the quality and quantity of yield. The effect of five set of variable temperature combinations of 23:9, 27:12, 33:19, 36:23 and 39:27°C at 75 ± 5 per cent humidity and 14 h photoperiod under laboratory conditions were studied on the stage-specific development, survival and life table parameters of N. lugens. The optimum temperature range lies between 27:12°C and 33:19°C as fecundity (102 ± 8.50–112 ± 3.75), per cent egg hatchability (86.86 ± 1.21–87.14 ± 1.99) and per cent viability of fifth nymphal instar was maximum at these combinations. Similarly, the net reproductive rate (R0) (163.49) and intrinsic rate of increase (rm) (0.1993 females female− 1 day− 1) were maximum at 33:19°C. Generation time (T) decreases significantly with increase in temperature. The finite rate of increase (λ) varied from 1.1522 to 1.1300 females female-1 day-1 with multiplication rate (erm)7 of 2.3821 to 4.2501, respectively, at temperature combinations of 23:9 to 39:27°C. The relatively high values of life table parameters at 33:19°C followed by 27:12°C temperature combinations suggests that N. lugens thrive well at these temperatures. The present studies can be helpful in understanding the adoption of N. lugens to higher range of temperature combinations under changing climatic conditions. The implications of this study also aids in predicting the population dynamics of N. lugens under field conditions and devising eco-friendly management strategies.

Published: May 2023

Background The phytocannabinoid cannabidiol (CBD) has been demonstrated to possess anti-inflammatory, anti-seizure, anti-oxidant, and proposed anti-obesity effects. Therapeutic modalities that improve the size of existing adipocytes through a reduction in hypertrophy, or result in increased hyperplasia (increased cell number) and decreased hypertrophy (enlarged cell size) during adipogenesis can result in smaller adipocytes that maintain insulin sensitivity, reducing the incidence of dysfunctional adipose tissue. The effect of timing CBD treatment to the proliferation (mitotic expansion) phase or the differentiation phase of pre-adipocytes on hyperplasia, hypertrophy, and expression of genes involved in triacylglycerol synthesis has not been investigated. We aimed to determine how exposing 3T3-L1 pre-adipocytes to CBD during the expansion or differentiation phase affected proliferation, cell size, and expression of enzymes involved in triacylglycerol synthesis.Methods Cells were treated with CBD at doses of 0.2 µM (low [CBD]) or 20 µM (high [CBD]) for measurement of cell viability and proliferation. Additionally, pre-adipocytes were exposed to CBD during proliferation and before stimulation of differentiation (expansion phase) or during the differentiation protocol (differentiation phase) and cell size, total lipid deposition and gene expression of acylglycerophosphate acyltransferase-2 (AGPAT2), diacylglycerol acyltransferase-2 (DGAT2), and glycerol-3-phosphate acyltransferase-3 (GPAT3) were quantified in the mature, lipid-storing adipocytes.Results The high CBD dose reduced cell viability and completely inhibited differentiation of pre-adipocytes into mature adipocytes when cells were treated during the differentiation period. Treatment of cells with the high CBD dose during the mitotic clonal expansion period significantly reduced but did not inhibit differentiation of the cells into the mature phenotype. The low CBD dose did not affect cell viability and resulted in increased proliferation and smaller mature adipocytes that did not differ from control cells with regards to lipid droplet deposition but that exhibited changes in gene expression of AGPAT and GPAT.Conclusions Our results suggest that a low (0.2 µM), physiologically achievable dose of CBD affects mature adipocyte cell size and gene expression of acyltransferases involved in triacylglycerol synthesis and that these effects are dependent on timing the CBD exposure to the cell’s mitotic clonal expansion phase.
Quantum federated learning in healthcare: The shift from development to deployment
and from models to data
Authors: Kais Sabre , Bhatia Amandeep , Alam Muhammad
Published: May 2023

Healthcare organizations have a high volume of sensitive data and traditional technologies have
limited storage capacity and computational resources. The prospect of sharing healthcare data
for machine learning is more arduous due to firm regulations related to patient privacy. The balanced
protection of confidentiality, integrity, and availability of healthcare data, has become a major
concern beyond classical data security considerations. In recent years, federated learning offers a
solution to accelerate distributed machine learning addressing concerns related to data privacy and
governance. Currently, the blend of quantum computing and machine learning has experienced significant
attention from academic institutions and research communities. Quantum computers have
shown the potential to bring huge benefits to the healthcare sector through efficient distributed
training across several quantum nodes. The ultimate objective of this work is to develop a quantum
federated learning framework (QFL) to tackle the optimization, security, and privacy challenges
in the healthcare and clinical industries for medical imaging tasks. In this work, we proposed
federated quantum convolutional neural networks (QCNNs) with distributed training across edge
devices. To demonstrate the feasibility of the proposed QFL framework, we performed extensive
experiments on medical datasets (Pneumonia MNIST, and CT-kidney disease analysis), which are
non-independently and non-identically partitioned among the healthcare institutions/clients. The
quantum federated global model maintained a high classification testing accuracy and generalizability
and outperformed the locally train clients regardless of how unbalanced the medical data
is distributed among the clients. The global model achieved the best performance as compared to
local clients in terms of the area under curve of the receiver operating characteristic curve (AUCROC)
(0.953) and an average of (0.98) on all classes for predicting outcomes on pneumonia and
CT-kidney datasets, respectively. Moreover, the client selection mechanism is proposed to reduce
the computation overhead at each communication round, which effectively improves the convergence
rate. The proposed quantum federated learning framework is validated and assessed via large-scale
simulations. Based on our results from numerical simulations, the deployment of distributed and
secure quantum machine learning algorithms for enabling scalable and privacy-preserving intelligent
healthcare applications would be extremely valuable.
Experimental studies of the influence of mobile fan positioning parameters on the ability to transport the air stream into a building
Authors: Kaczmarzyk Piotr , Warguła Łukasz , Janik Paweł
Published: May 2023

The article aims to determine the influence of fan positioning parameters, i.e., its distance from a door opening (1 m to 7 m) and the angle of inclination of the impeller axis in relation to the ground (0° to 18°) on the amount of air flow pumped through a door opening. The volumetric air flow stream was determined based on measuring (at fifty measuring points) the velocity of the air stream blown onto the surface of the door opening. Four commercial positive pressure ventilators, commonly used in rescue operations, with a power of 0.6 kW to 6.3 kW were tested. The tests showed that the value of the air flow stream at the most favorable setting (distance in the range of 3 m to 5 m and the angle of the impeller axis to the ground in the range of 5° to 12.2°) is included in the range of 18304 ± 2460 m3/h to about 45189 ± 4619 m3/h. Such settings cause the air stream to be aimed at the central area of the door opening. Imprecise mobile fan arrangement may reduce the flow rate from 41% to 76% in relation to the most favorable results.

Background
In this study, we investigated the mechanism by which excessive salt intake aggravates atherosclerosis by evaluating the changes in the gut microbiota, the expression of nutrient transporters in the gut, and the fatty acid composition in atherosclerosis.
Results
Sixteen-week-old male ApoE-deficient mice were either fed a high-fat, high-sucrose diet (HFHSD) or HFHSD, high-salt diet (HFHSD + 4%NaCl) for 8 weeks. The HFHSD + 4%NaCl group showed progression of atherosclerosis, and gut microbiota analysis revealed that this group had a reduced abundance of Allobaculum spp., Ruminococcaceae family, Lachnospiraceae family, and Alphaproteobacteria class compared to the HFHSD group. Furthermore, Cd36 gene expression levels were increased in the small intestine of the HFHSD + 4%NaCl group compared to those in the HFHSD group. The concentration of saturated fatty acids in serum and atherosclerotic lesions, was remarkably increased in the HFHSD + 4%NaCl group.
Conclusions
Dysbiosis induced by excessive salt intake increases the expression of long-chain fatty acid transporters in the intestinal tract, which increases the influx of saturated fatty acids into the body.
