Abstract
An effective antibacterial edible film made from chitosan-l-lysine incorporating cinnamon essential oil were developed. This study aims to optimize the effectiveness of chitosan, L-lysine, and Cinnamon essential oil concentration to against some foodborne pathogens using a Box-Behnken designs (BBDs) with Response Surface Methodology (RSM). Based on the statistical analysis, L-lysine and cinnamon essential oil has the significance effect to against the foodborne pathogens (Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli and Salmonella enteritidis) proved by the p value<0.5 and the increase of bacteria in inhibition zone. The result showed the optimum formulation of edible film is chitosan 0.71g, L-lysine 0.5g, and Cinnamon essential oil 0.75ml.
Reinforcement to concrete bond strength: a comparison between normal concrete and various types of concrete
Authors: Rohman R K , Kristiawan S A , Saifullah H A , Basuki A 
Published: March 2022

Abstract
This paper describes the bond strength comparison between concrete and reinforcement with several types of concrete. The types of concrete studied were normal concrete (NC), Self-Compacting Concrete (SCC), High-Volume Fly Ash Concrete (HVFAC), and High-Volume Fly Ash Self-Compacting Concrete (HVFA-SCC). Research data were obtained from previous studies. The data of concrete bond strength were obtained by testing the reinforced concrete beam with a lap splice in the tensile moment area. Bond strength values were normalized by dividing with the square root of concrete grade. Then use normalized data to formulate the relationship between the length of lap splice to diameter ratio (ls/db) and the normalized bond strength concrete for both normal concrete and SCC. From the obtained relationship, we can compare the bond strength between NC and SCC. The SCC bond strength is higher than NC. Bond strength of HFVAC and HVFA-SCC is also higher than NC and SCC, so that the use of HVFA-SCC can reduce the need for lap splice.

Published: March 2022

Abstract

Moringa oleifera oleifera Lam leave contains quercetin which has anti-inflammatory activity, with the mechanism of action reducing mast cell activity through the NF-kB pathway. The topical patch of Moringa oleifera leave ethanolic extract was develop as an alternative to oral anti-inflammatory side effects, including first-pass metabolism and gastric irritation. Polymer is the main component of a patch matrix system because it functions to control drug release. Alpha-cellulose (AC) and polyvinyl alcohol (PVA) are hydrophilic polymers with different properties and functions. PVA forms a pore that can control the drug release while AC has a strong barrier film so that the polymer combination can produce a patch matrix that meets the requirements. The combination of PVA and AC with a ratio of 1:2; 1:1; 2:1; then analyze for organoleptic, thickness, weight, folding endurance, moisture content, and pH. The concentration of quercetin in extracts and patch, and in vitro test. Statistical analysis was carried out to determine the effect of polymer combination. The results showed the combination of PVA and AC patch matrix of Moringa oleifera leaves extract had a significant effect on the physicochemical properties there are thickness, patch weight, and moisture content, but they did not affect folding endurance and pH. The ratio of PVA and AC of 1:2 is the chosen formula because it meets the patch requirements. The concentrations of quercetin in the extract is 14.21% w/w. The percentage of total flavonoid that released from patch was 37.23% for 5 hours. The release kinetics followed the Higuchi kinetics model with a diffusion mechanism.

Published: March 2022

Abstract
Zinc oxide nanoparticles are potential metal oxide for antioxidant agent. This paper investigates antioxidant activity of cerium-doped zinc oxide (Ce-doped ZnO) nanoparticles. Ce-doped ZnO nanoparticles was prepared by precipitation method with calcination temperature of 200˚C. The product of precipitate was characterized by X-ray diffraction measurement, and UV-Vis spectrophotometer. The antioxidant activity of Ce-doped ZnO nanoparticles was investigated using 1,1-diphenyl-2-pcrylhydrazyl (DPPH) method. The X-ray diffraction pattern showed the growth of Ce-doped ZnO crystalline structure of hexagonal wurtzite with crystallite size of 42 nm. UV-Vis absorbance spectrum analysis revealed the band gap energy of Ce-doped ZnO nanoparticles was smaller than band gap energy of bulk ZnO. Ce-doped ZnO nanoparticles could scavenge DPPH free radicals and exhibited moderate antioxidant activity.

Abstract
Ozone can be produced by plasma processing. Plasma is the fourth form of matter after gas when the gas is energized to be ionized or charged. To achieve efficient energy, the monitoring plasma production process is required. In this study, the plasma analysis was successfully carried out using simultaneous current-voltage measurement. The equipment was set in an ozone plasma generator consisting of an MQ-131 gas ozone sensor, PZEM-004T power sensor, DHT22 sensor for room temperature and humidity, MLX-90614 infrared temperature sensor, and Arduino Mega 2560, connected to an oscilloscope. Ozone device and sensors give and extract data to measure power and the ionization energy in ozone generation. The calculation results show the ionization energy with the highest value of 8.4 x 10“7 loule and the lowest value of 2.82xl014Ioule.
Resampling schemes in population annealing — numerical results
Authors: Gessert Denis , Weigel Martin , Janke Wolfhard 
Published: March 2022

Abstract
Population annealing (PA) is a population-based algorithm that is designed for equilibrium simulations of thermodynamic systems with a rough free energy landscape. It is known to be more efficient in doing so than standard Markov chain Monte Carlo alone. The algorithm has a number of parameters that can be fine-tuned to improve performance. While there is some theoretical and numerical work regarding most of these parameters, there appears to be a gap in the literature concerning the role of resampling in PA. Here, we present a numerical comparison of a number of resampling schemes for PA simulations of the 2D Ising model.
Phase diagram of the dodecahedron spin model on square lattice with diluted bonds
Authors: Yunita S. , Rahmat R. , Surungan T. 
Published: March 2022

Abstract
We study the effect of bond dilution of a dodecahedron spin model on ferromagnetic square lattice. The dodecahedron spin constitutes a discrete (polyhedral) counterpart of the continuous Heisenberg spin. Previous work found that, in the absence of dilution, the ferromagnetic dodecahedron system exhibits a finite temperature phase transition. We use Monte Carlo simulation with Wolff cluster algorithm to monitor how phase transitions are impacted by the bond dilution. We simulate the model with various bond concentrations and investigate the resulting phase diagram and critical behavior.

Authors: Suzuki D , Hori T , Miura S 
Published: March 2022

Abstract
In this paper, a simple method to improve sampling efficiency of the generalized hybrid Monte Carlo (GHMC) method is presented. Compared to the standard GHMC method, our method is found to allow us to safely increase the time increment for solving an equation-of-motion in the GHMC calculations by a factor of 4. We have demonstrated various algorithmic parameter dependence on the sampling efficiency of a hydrated alanine dipeptide.
Interaction between PET tracer and the specific residues around the gate of the open form of Monoamine Oxidase B (MAO-B)
Authors: Ottawa M , Miyashita N 
Published: March 2022

AbstractMonoamine Oxidase B (MAO-B) is the enzyme that metabolizes a monoamine neurotransmitter. Recently, a PET tracer targeting MAO-B, SMBT-1, has been developed as the biomarker of neurodegenerative diseases. However, the detailed binding mode of SMBT-1 has not been clear. To clarify the binding mode of SMBT-1 on MAO-B, we performed the molecular dynamics (MD) simulations of MAO-B in the outer mitochondrial membrane and the complex of MAO-B to SMBT-1, and the docking simulation of MAO-B with SMBT-1. We found that the Leu88, Leu171, Ile199, and Tyr326around the substrate-binding site interact with SMBT-1. These hydrophobic residues mainly support the two aromatic rings of the center of SMBT-1, making the stable binding of SMBT-1.
Role of temperature and alignment activity on kinetics of coil-globule transition of a flexible polymer
Authors: Paul Subhajit , Majumder Suman , Janke Wolfhard 
Published: March 2022

Abstract
We study the nonequilibrium kinetics during the coil-globule transition of a flexible polymer chain with active beads after a quench from good to poor solvent condition using molecular dynamics simulation. Activity for each bead is introduced via the well-known Vicsek-like alignment rule due to which the velocity of a bead tries to align towards the average direction of its neighbors. We investigate the role of quenching temperature with varying activity during collapse of this polymer. We find that although for lower activities the kinetics remains qualitatively similar for different temperatures, for higher activity noticeable differences can be identified.
Compressed sensing based on QUBO formulation
Authors: Kudo Kazue 
Published: March 2022

AbstractIsing machines efficiently solve the combinatorial optimization problems described by the Ising model or the quadratic unconstrained binary optimization (QUBO) formulation. A hybrid method based on the QUBO formulation for compressed sensing is proposed. The proposed method comprises alternative steps of discrete and continuous optimization. In the discrete optimization step, the objective function is described by the QUBO formulation. Successful examples obtained via the proposed method are demonstrated. The performance of the proposed method depends highly on the initial conditions.
The formation of dark-matter-deficient galaxies through galaxy collisions
Authors: Otaki Koki , Mori Masao 
Published: March 2022

Abstract
In the standard galaxy formation model, cold dark matter (CDM) drives the hierarchical structure formation. However, recently it is suggested that the satellite galaxy NGC1052-DF2, a member of the elliptical galaxy NGC1052 group, has a very little dark matter component compared to the theoretical predictions. 27 dark-matter-deficient galaxies have been discovered, but it is difficult to explain their formation process in the CDM model. We investigate the formation process through dark matter subhalo (DMSH) collisions using three-dimensional numerical simulations. As a result, we show the bifurcation sequence of the formation of dark-matter-dominated galaxies and dark-matter-deficient galaxies. In the case of low-speed collisions, a merger of the two DMSHs produces dark-matter-dominated galaxies. However, the two DMSHs penetrate each other, but the gaseous mediums collide for the middle-speed encounter. The enhancement of the gas density induces a burst of star formation, and then a dwarf galaxy without a dark matter halo forms at the interface of the DMSH collision.

Published: March 2022

Abstract
Graphitization of the (111) face of diamond irradiated with fast neutrons under single pulses of the third harmonic of a Ti: sapphire laser (100 fs, 266 nm) is investigated. Transformations of the structure of the graphitized material along the surface of laser spots formed by the pulses at different energies are investigated by confocal Raman spectroscopy. It is found that irradiation of diamond with fast neutrons lowers the graphitization threshold by about five times compared with that of unirradiated diamond.

Abstract
In this work we study zinc oxide nanostructures of various geometries synthesized via the hydrothermal technique on Si (111) substrate. We demonstrate capabilities of the growth protocol for control over the morphology of nanostructures varying from nanowires to hexapods. The obtained samples were studied by photoluminescence spectroscopy to demonstrate a very narrow spontaneous emission near 370 nm. Despite cheap and feasible fabrication, the obtained nanostructures possess high crystallinity confirmed by the absence of typical for ZnO wide emission band in the visible region, related with the structure imperfections. This property together with the capabilities of the geometrical control over the nanostructures unveil perspectives of the reported approach for future UV photonic applications.

/Si superlattices (SL) grown on silicon substrates by molecular beam epitaxy. It was shown that the addition of Sn (y = 0.07) to the alloy layers within the structures results in a significant shift of the photoluminescence (PL) spectra towards longer wavelengths (2.0-3.5 μm) compared to similar Ge0.7Si0.3/Si superlattices. A series of experiments involving etching the structures to different depths have shown that the observed photoluminescence occurs exactly in the Ge1-x-y

/Si SL region, with the sublinear nature of the PL power dependence indicating the probable participation of defects in radiative recombination. A significant increase in low-temperature PL was observed with a decrease in the thickness of narrow-gap SL layers from 6 to 2 nm, as well as with an increase in the number of superlattice periods from 10 to 30. The obtained structures exhibit relatively good temperature stability of luminescence, which is preserved up to 160 K. Thus, the current work demonstrates the possibility of creating mid-wave IR emitting epitaxial structures on silicon substrates.

Abstract
We present a photoluminescence study of In(As,P) monolithic nanoinclusions into Si (100) substrates. The structures were grown in openings of the silicon substrates using an original approach based on the metal-organic vapor epitaxy method. The obtained arrays of In(As,P) nanoinclusions into the Si (100) surface were investigated by scanning microphotoluminescence spectroscopy. The obtained results show high crystalline quality of In(As,P) inclusions with broad emission peak in the near-infrared range of wavelengths.
Control of the morphology of silver dendrites formed by glass electrolysis
Authors: Lubyankina E A , Babich E S , Lipovskii A A , Kryzhanovskaya N V 
Published: March 2022

AbstractWe demonstrate a new technique to fabricate silver dendritic structures in a subsurface glass layer based on electrolysis of silver-enriched glass. Chemical etching of glass in water diluted HF allows “opening” of the dendrites for their characterization, which makes possible their use for Surface-enhanced Raman scattering. The structure and morphology of the dendrites were characterized using atomic force and scanning electron microscopy, and energy-dispersive X-ray spectroscopy. It was demonstrated that the surface morphology of the formed structures depends on the electric charge passed through the sample during the electrolysis and the duration of the chemical etching. The presented method does not require expensive equipment and materials and allows one to form silver nanostructures of a prescribed pattern.

Abstract
For the Phase-II Upgrade of the ATLAS Detector, the Inner
Detector will be replaced with the Inner Tracker (ITk), consisting
of a pixel and a strip tracker. The 17,888 silicon strip detector
modules comprising the ITk strip tracker will be assembled from
silicon strip sensors and flexes with readout chips in a manual
assembly process performed at 20 module assembly sites in a complex
distribution chain, which requires quality control steps to be
performed after each distribution and assembly step.

Sensor quality control requires a visual inspection of the full
sensor area (about 100 cm2) of each sensor to detect and log any
defects (e.g. scratches, breakdown areas or chipped corners) or
contamination. Since manual surveys of full sensor areas for several
thousand sensors are both time-consuming and prone to errors,
alternative methods were investigated to automate the process and
improve its reliability.

This paper presents a setup developed to take high-resolution images
of full silicon strip sensors with high repeatability quickly and an
algorithm developed for the automated detection of defects, built
using functions and filters from popular open-source visual
processing packages OpenCV and Scikit-image. Methods were developed
both for small-scale high-resolution images and full-size sensor
images with lower resolution — both are presented here.

I describe the interplay between Minkowski and Euclidean signature gamma matrices, Majorana fermions, and discrete and continuous symmetries in all spacetime dimensions.

Exact percolation probabilities for a square lattice: site percolation on a plane, cylinder, and torus
Authors: Akhunzhanov R K , Eserkepov A V , Tarasevich Y Y 
Published: March 2022

Abstract
We have found analytical expressions (polynomials) of the percolation probability for site percolation on a square lattice of size L × L sites when considering a plane (the crossing probability in a given direction), a cylinder (spanning probability), and a torus (wrapping probability along one direction). Since some polynomials are extremely cumbersome, they are presented as separate files in supplemental material. The system sizes for which this was feasible varied up to L = 17 for a plane, up to L = 16 for a cylinder, and up to L = 12 for a torus. To obtain a percolation probability polynomial, all possible combinations of occupied and empty sites have to be taken into account. However, using dynamic programming along with some ideas related to the topology, we offer an algorithm which allows a significant reduction in the number of configurations requiring consideration. A rigorous formal description of the algorithm is presented. Divisibility properties of the polynomials have been rigorously proved. Reliability of the polynomials obtained have been confirmed by the divisibility tests. The wrapping probability polynomials on a torus provide a better estimate of the percolation threshold than that from the spanning probability polynomials. Surprisingly, even a naive finite size scaling analysis allows an estimate to be obtained of the percolation threshold p

The Judgment of the Appeals Chamber of the International Criminal Court of 5 March 2020 in the Case of Afghanistan
Authors: Bula-Bula Sayeman 
Published: March 2022

Abstract
This study seeks to show that the Appeals Chamber of the ICC responsible for the ruling on the case of the armed conflict in Afghanistan has made an inchoate historic judgment. The analysis focuses on two main points: First, the reasoning made by the Prosecutor that the Pre-Trial Chamber abused its discretion in assessing the “interests of justice”; and second, the assessment of the scope of the procedural act. Finally, the unprecedented ruling of the ICC can consolidate the progressive positivism which now seems to be spreading across many areas of international law.
