Advanced Approach towards Zero Waste: Modeling of Copper Recovery from e-Waste by Using Machine Learning Technique
Authors: Srivast Sunil Kumar , Shrivastava Rahul Kumar 
Published: June 2023

Abstract
E-waste contains significant proportions of hazardous materials, metals, and polymers, including toxic chemicals, which pose an enormous threat to contaminating the environment. This study promotes the concept of zero waste by recycling valuable metals from a scrap of e-waste. The recovery of precious metals like copper from e-waste is a challenging task, considering the selection of a suitable methodology and further optimizing the adopted methods. The recovery of precious metals and waste management through recycling hazardous waste can reduce the harmful impact of these chemicals on the environment. This study reveals an efficient methodology for the recovery of copper and further developed a model using the popular Machine Learning Technique. A model was developed using Machine Learning Techniques, Artificial Neural Networks (ANN), and Boosting Algorithm (BA). Boosting Algorithm preferred over ANN due to better results and high accuracy for predictability. Four variables (H2SO4, H2O2, Solid/Liquid ratio, and Reaction Time) were utilized in developing this model. The developed model results and findings will be valuable to copper recovery, e-waste management, and hazardous waste management. In addition, the proposed model can facilitate efficient automation of the copper recovery process at the industrial level.

Abstract
This work reports the epitaxial growth of 8.5 µm-thick GaN layers on 200 mm engineered substrates with a polycrystalline AlN core (QST®) for CMOS compatible processing of vertical GaN power devices. The epitaxial stack contains a 5 \(\mu\)m thick drift layers with a Si doping density of 2x1016 cm− 3 and total threading dislocation density of 4x108 cm− 2. The thick drift layer requires fine-tuning of the epitaxial growth conditions to keep wafer bow under control and to avoid the formation of surface defects. Diode test structures processed with this epitaxial stack achieved hard breakdown voltages > 750 V, which is shown to be limited by impurity or metal diffusion from the contact metal stack into threading dislocations. Conductive Atomic Force Microscopy (cAFM) reveals some leakage contribution from mixed type dislocations, which have their core structure identified as the double 5/6 atom configuration by scanning transmission electron microscopy images. Modelling of the leakage conduction mechanism with one-dimensional hopping conduction shows good agreement with the experimental data, and the resulting fitting parameters are compared to similar findings on silicon substrates. The outcome of this work is important to understand the possibilities and limitations of vertical GaN devices fabricated on large diameter wafers.

Abstract

Purpose:
Non-small cell lung cancer (NSCLC) is Argentina's first cause of cancer death. Most patients have an advanced stage at diagnosis, with poor expected survival. This study aimed to characterize the health-related quality of life and economic impact of patients treated in the private healthcare sector and compare it to that of the public sector.
Methods:
We undertook an observational cross-sectional study that extended a previous study to a referral private center in Argentina. Outcomes included the EuroQol EQ-5D-3L (to assess health-related quality of life), COST (financial toxicity instrument), WPAI-GH (to assess productivity loss), and out-of-pocket expenses in adults diagnosed with NSCLC.
Results:
We included 30 consecutive patients from a private healthcare center (July 2021 to March 2022), totaling 131 patients (N = 101 from previous public study). The whole sample had low quality of life, and relevant economic impact. Patients in the private healthcare sector showed lower disease severity, higher educational level and household income. In addition, private healthcare system patients showed higher utility (0.77 vs. 0.73; p = 0.049) and lower impairment of daily activities (41% vs. 59%; p = 0.014). Private health system patients showed also lower financial toxicity as measured by the COST score (23.9 vs. 20.14; p = 0.036) but showed no differences when financial toxicity was assessed as a dichotomic variable.
Conclusions:
Though patients with NSCLC treated in a private healthcare center in Argentina showed a significant health-related quality of life and economic impact, this impact was smaller than the one observed in publicly funded hospitals.
The Maker-Maker domination game in forests
Authors: Duchêne Eric , Dumas Arthur , Oijid Nacim , Parreau Aline , Rémila Eric 
Published: June 2023

Abstract
We study the Maker-Maker version of the domination game introduced in 2018 by Duchêne et al. Given a graph, two players alternately claim vertices. The first player to claim a dominating set of the graph wins. As the Maker-Breaker version, this game is PSPACE-complete on split and bipartite graphs. Our main result is a linear time algorithm to solve this game in forests. We also give a characterization of the cycles where the first player has a winning strategy.

Abstract
Live-cell imaging is a popular method for analyzing mammalian preimplantation embryos, but it often requires expensive equipment and skilled techniques. We previously developed a simply and costly embryo-culture system in a sealed tube that does not require a CO2 incubator. In the present study, we developed a new live-cell imaging system using our previous culture method and a glass capillary. Zygotes were placed in a glass capillary and sunk in oil for observation under a stereomicroscope. Warming the capillary using a thermoplate enabled most of the zygotes to develop into blastocysts and produce healthy offspring. This live-cell imaging system captured images every 30 min for up to 5 days, which confirmed that the developmental speed and quality of the embryos were not affected, even with fluorescence. Overall, this new system is a reasonable, cost-effective, live-cell imaging method for preimplantation embryos that does not require dedicated machines and advanced techniques.
Correlates of Early Initiation of Breastfeeding Among Mothers in Western Region: Insight from the 2014 Ghana Demographic and Health Survey
Authors: Sackey Jonathan , Lokko Christiana , Lokko Francis , Arhin Rebecca 
Published: June 2023

Abstract
Background: According to the World Health Organization (WHO), initiation of breastfeeding (EIBF) within one hour of birth protects the newborn from acquiring infection and reduces newborn mortality. This notwithstanding there is anecdotal evidence that suggests that in some parts of Ghana, the practice of EIBF is affected by multiple factors which have not been well interrogated.
Hence the study assessed the determinants of early initiation of breastfeeding in the Western Region (WR).
Methods: The study explored the 2014 child file of the Ghana demographic and health survey (GDHS) data. The data was weighted and filtered by region (Western Region) and children 24 months or 0-23 months of age using the SPSS Version 20. A sample size of 257 children was obtained. Results were presented using frequencies, bivariate and binary logistic regression. Statistical significance was pegged at p<0.05
Results: The findings of this study indicate that maternal, paternal, household and community factors did not predict EIBF. However, initiation of EIBF in WR was predicted by the child and institutional factors. Female( and higher birth order children were less likely to be breastfed within 1 hour. However, average-size children and children whose mothers had high access to healthcare were more likely to be breastfed within 1 hour.
Conclusions: There is a high prevalence of early EIBF in the Western Region (78.2%). Nevertheless, Ghana Health Service must include in child health initiatives early EIBF policies targeting female and higher birth order children.

Published: June 2023

Abstract
The existence of broadly cross-reactive antibodies that can neutralize diverse HIV-1 isolates (bnAbs) has been appreciated for more than a decade. Many high-resolution structures of bnAbs, typically with one or two well-characterized HIV-1 Env glycoprotein trimers, have been reported. However, an understanding of how such antibodies grapple with variability in their antigenic targets across diverse viral isolates has remained elusive. To achieve such an understanding requires first characterizing the extent of structural and antigenic variation embodied in Env, and then identifying how a bnAb overcomes that variation at a structural level. Here, using hydrogen/deuterium-exchange mass spectrometry (HDX-MS) and quantitative measurements of antibody binding kinetics, we show that variation in structural ordering in the V1/V2 apex of Env across a globally representative panel of HIV-1 isolates has a marked effect on antibody association rates and affinities. We also report cryo-EM reconstructions of the apex-targeting PGT145 bnAb bound to two divergent Env that exhibit different degrees of structural dynamics throughout the trimer structures. Parallel HDX-MS experiments demonstrate that PGT145 bnAb has an exquisitely focused footprint at the trimer apex where binding did not yield allosteric changes throughout the rest of the structure. These results demonstrate that structural dynamics are a cryptic determinant of antigenicity, and mature antibodies that have achieved breadth and potency in some cases are able to achieve their broad cross-reactivity by “threading the needle” and binding in a highly focused fashion, thus evading and overcoming the variable properties found in Env from divergent isolates.
Research on point cloud hole filling and 3D reconstruction in reflective area
Authors: Sun Chao , Wang MeiYuan , Miao LongXin , Shi Jiuye , Ding JianJun 
Published: June 2023

Abstract
3D reconstruction is the process of obtaining the three-dimensional shape or surface structure of an object, which is widely used in advanced manufacturing fields such as automotive, aerospace, industrial inspection, and reverse engineering. However, due to the structural characteristics of the component itself, the reflective properties of the coating material, and other factors, there may be specular reflection during image acquisition, making it difficult to achieve complete 3D reconstruction of the component. This paper proposes a method to address the problem of incomplete 3D reconstruction of strongly reflective objects by recognizing outlier points and filling point cloud holes. The proposed View-Transform-PointNet outlier point recognition network improves the alignment of the initial point cloud plane and implements secondary alignment of the point cloud based on the perpendicularity between the outlier plane in mixed reflection and the point cloud plane. The point cloud hole-filling method is based on the principle of outlier formation and approximates a local Gaussian distribution to linear variation. The distance between the end of each outlier plane and the real surface is calculated to repair the depth information of outlier points. The proposed method achieves a 39.4% increase in the number of point cloud filling, a 45.2% increase in the number of triangular mesh faces, a 46.9% increase in surface area, and a chamfer distance (CD) of 0.4471009, which is better than existing geometric repair methods in terms of standard deviation and smoothness. The method improves the alignment of initial point cloud planes and enhances the accuracy of outlier point recognition, which are the main innovative points of this study. The 3D reconstruction of the repaired point cloud model is achieved through Poisson equation and parameter adjustment. The proposed method reduces the error caused by large curvature in the boundary region and improves the smoothness and accuracy of the reconstructed model.

Abstract

The common bean (Phaseolus vulgaris) has recently gained popularity as a dietary supplement substitute for enhancing human health. Humans need nutrition on a basic level; however, many people still struggle to meet their Zn and Fe requirements. In plants the uptake, transport, and accumulation of microelements (Zn and Fe) are significantly regulated by the ZIP transporter. Here, we present information on the ZIP gene of metal transporters inPhaseolus vulgaris. ZIP gene was identified through PCR which resulted of 133bp and sequence of ZIP gene having 235bp, was submitted to NCBI with accession no. MH845642 after BLAST analysis. The resulted sequence was further analysedIn-silicoviz. BioEdit, Mega5 and a phylogenetic tree was constructed. The expression level of ZIP gene was measured by Q-PCR using cox gene as an internal control. Different expression levels were obtained for 3, 6, and 12hrs time periods of exposure to zinc treatment at different concentrations 100 mM, 150 mM and 200 mM respectively. The relative expression of treated and untreated (control) ofP. vulgariscotyledons was calculated using BioRad IQ-5 software. OverallZIPgenes expression was highest at 200 mM for 12 hr (3.5fold) followed by zinc treatment at 200 mM for 6 hr (2.3fold) and lowest at 150 mM for 3hr (0.5fold). This study systematically analysed the gene structure, expression profiles, regulatory network, and the biological function of the ZIP family inPhaseolus vulgarisL., providing better understanding of the regulatory roles of ZIP genes and contributing to improve nutrient quality of crops.
The First Steklov Eigenvalue on Infinite Subgraphs of Integer Lattices
Authors: CHEBBI Yassin 
Published: June 2023

Abstract
In the context of transient graphs, we study the first Steklov eigenvalue σ0(Ω) of an infinite subgraph with finite boundary (Ω, B) of the integer lattice Zn. We focus in this paper on finding lower bounds using the technique of discretization of smooth compact Riemannian manifolds with cylindrical boundary. These bounds essentially depend on the discretization of the sphere Sn ⊂ Rn+1 with two identical boundaries’ isometrics to {1} × Sn−1 through quasi-isometries. As a consequence, if n ≥ 4 and the boundary B considered as a finite subset of Zd where 1 ≤ d ≤ n − 3, we show that σ0(Ω)|B| 1/n−1 tends to infinity as the cardinal of B tends to infinity. Moreover, if n ≥ 3 and the boundary B is a sphere, we prove that the first Steklov eigenvalue tends to zero proportionally to 1/|B| 1/n−1 as the radius tends to infinity and that σ0(Ω)|B| 1/n−1 is bounded.

Authors: Mastriani Mario 
Published: June 2023

Abstract
In this study, we present a simplified version of the quantum teleportation protocol for n-qubits and a generalized version of the superdense coding protocol for n-bits; in both cases, thanks to the cascade splitting technique. Both protocols will be analyzed on three notably different platforms: Quirk simulator, IBM QASM simulator of the IBM Q Experience program, and an optical table. The experiments on the three platforms show the excellent performance of both protocols. Finally, an analysis, about the immunity of these protocols in the presence of an eavesdropper is incorporated.
Optimization of Time Dependent Fuzzy Multi-Objective Reliability Redundancy Allocation Problem for n-Stage Series Parallel System

Published: June 2023

Abstract
This study introduces a time dependent fuzzy multi-objective reliability redundancy allocation problem (TF-MORRAP) for the $n$-stage (level) series parallel system. System reliability maximization and system cost minimization according to time by optimizing the redundant components counting at every stage of the system is the main objective of this study. This optimization is done by satisfying the entropy constraints with limited redundant components at every stage and in the whole system. The reliability and cost of every component are represented as triangular fuzzy numbers (TFN) to handle the uncertainty of input information of the system. According to time the component reliability and cost decrease by some factor of their previous existing value. This factor follows the change in the length of radius of the inverse logarithmic spiral with respect to angle which is regarded as time here. The proposed problem is analysed by using an over-speed protection system of a gas turbine. We compare the membership values of optimal solutions obtained by using two well-known techniques namely Non-dominated sorting genetic algorithm-II (NSGA-II) and a multi-objective particle swarm optimization algorithm called NF-MOPSO. Various performances of the algorithms are compared to solve the aforementioned problem by using some performance metrics. NF-MOPSO shows the high satisfaction level of objective functions and better performance than NSGA-II.

Published: June 2023

Abstract

FPGAs promise significant performance improvements for several computations in cloud applications. However their shared use in multi-tenant scenarios makes them susceptible for attacks. Different fromclassical scenarios, where the attacker has hardware access to the device, in cloud scenarios the attackis possible only from remote. As a consequence remote SCA attacks gained increasing attention inthe last years. These attacks exploit that attacker and victim share with the same FPGA also thesame PDN so that operation dependant voltage fluctuations caused by the victim’s IP are observableby a voltage sensor of the attacker. While previous attacks in this domain focused on cryptographicalgorithms, this work provides insights in an attack on a PUF primitive, the Loop PUF. This primitiveis an interesting target for the attack since it might be used, e.g., for storing or deriving secret keyson a remote FPGA. We introduce and discuss the setup of such a remote SCA using a TDC-basedvoltage sensor. With this sensor, we compare the performance of classical and remote SCA attackson the Loop PUF using two different Artix-7 FPGAs and demonstrate and discuss findings regardingsampling frequency and placement. This work extends and deepens the analysis from a previously published analysis at the ASHES Workshop 2022. In particular it provides insights into the influenceof repeated measurements, measurement time, and usage multiple TDCs on the attack performance.It also discusses the applicability of the attack to further RO-based PUF primitives. Overall the resultshow that remote SCA attacks on PUFs in a multi-tenant FPGA scenario have to be considered as asevere attack vector in the future.
