Published: March 2023

Abstract
Compressed sensing algorithm can be used in color ghost imaging to restore the image of object at the less demand of measurements times. However, the quality of the reconstructed color image is usually not satisfactory. In this paper, we propose a sequential color ghost imaging method that can complete color ghost imaging in a simple architecture and improve the quality of color image, which is optimize compressed sensing that can get better result of compressed sensing algorithm by post-processing the measurement matrix and establishing a new compressed sensing process. Under the condition of the same measurement times and reconstruction algorithm, compared with the unpost-processing one, the quality and detail of reconstructed image by the post-processing measurement matrix is quite improved especially with the increase of measurement times. Discussions on factors affecting the quality of the new compressed sensing process, such as the number of measurement and the detection noise intensity, are also conducted. Numerical simulation and physical experiment verified our proposed method.
Photodetecting properties on Sn-doped Bi2S3 thin film fabricated by nebulizer spray pyrolysis technique
Authors: Ganesh V , AlAbdulaal T H , Yahia I S 
Published: March 2023

Abstract
Metal chalcogenides have recently gained intensive attention due to their tunable bandgap energy, optoelectronic characteristics, and exceptional optical absorption. Because of the potential advantage of photodetectors, photovoltaic, holographic recording systems, and field-effect transistors, bismuth tri-sulfide (Bi2S3) crystals, in particular, have attracted a lot of focus in scientific research. In this study, the low-cost nebulizer spray technique was employed to synthesize the proposed Bi2S3:Sn thin films on glass substrates, varying the Sn doping concentrations in Bi2S3 films (from 1 to 3%). The crystallites of the orthorhombic-structured polycrystalline Bi2S3 films were all oriented in the same direction (130). According to the XRD spectra, preferred orientation and crystalline quality were improved by Sn doping concentrations up to 2%, but, above 2% of the Sn doping ratio, the structural properties were decreased. With increasing Sn-doping levels, the estimated direct band gap (Eg) of the Bi2S3:Sn films decreased, reaching a low value of 2.01 eV at 2% Sn and then rising. A field emission scanning electron microscope (FESEM) was applied to determine the size and shape of the grains in prepared Sn: Bi2S3 films.The 2% Sn-doped Bi2S3 thin film may be more appropriate for high-speed optoelectronic devices due to its high responsivity (1.24 AW−1), external quantum efficiency (40%), and detectivity properties (1.83 × 1010Jones). A potential mechanism for photodetector performance in the presence of air and UV radiation was also discussed in the present work for the proposed Sn: Bi2S3 thin films.
Cosmological distances with general-relativistic ray tracing: framework and comparison to cosmographic predictions
Authors: Macpherson Hayley J. 
Published: March 2023

Abstract
In this work we present the first results from a new ray-tracing tool to calculate
cosmological distances in the context of fully nonlinear general relativity. We use this tool to
study the ability of the general cosmographic representation of luminosity distance, as truncated
at third order in redshift, to accurately capture anisotropies in the “true” luminosity
distance. We use numerical relativity simulations of cosmological large-scale structure formation
which are free from common simplifying assumptions in cosmology. We find the general, third-order
cosmography is accurate to within 1% for redshifts to z ≈ 0.034 when sampling scales
strictly above 100 h
-1 Mpc, which is in agreement with an earlier prediction. We find the
inclusion of small-scale structure generally spoils the ability of the third-order cosmography to
accurately reproduce the full luminosity distance for wide redshift intervals, as might be
expected. For a simulation sampling small-scale structures, we find a ∼ ±5% variance in
the monopole of the ray-traced luminosity distance at z ≈ 0.02. Further, all 25 observers
we study here see a 9–20% variance in the luminosity distance across their sky at z ≈
0.03, which reduces to 2–5% by z ≈ 0.1. These calculations are based on simulations and
ray tracing which adopt fully nonlinear general relativity, and highlight the potential importance
of fair sky-sampling in low-redshift isotropic cosmological analysis.

Abstract
The production of vector boson tagged heavy quark jets potentially provides new tools to probe the jet quenching effect. In this paper, we present the first theoretical study on the angular correlations (

), transverse momentum imbalance (

), and nuclear modification factor (

) of

boson tagged b-jets in heavy-ion collisions, which was performed using a Monte Carlo transport model. We find that the medium modification of the

for

+ b-jet has a weaker dependence on

+ jet, and the modification patterns are sensitive to the initial jet

distribution. Additionally, with the high purity of the quark jet in

+ (b-) jet production, we calculate the momentum imbalance

and the nuclear modification factor

of

+ b-jet in Pb+Pb collisions. We observe a smaller

and larger

+ b-jet in Pb+Pb collisions relative to those of

+ jet, which may be an indication of the mass effect of jet quenching and can be tested in future measurements.
Regular black holes with improved energy conditions and their analogues in fluids*
Authors: Lan Chen , Miao Yan-Gang , Zang Yi-Xiong 
Published: March 2023

Abstract
On the premise of the importance of energy conditions for regular black holes, we propose a method to remedy those models that break the dominant energy condition, e.g., the Bardeen and Hayward black holes. We modify the metrics but ensure their regularity at the same time, so that the weak, null, and dominant energy conditions are satisfied, with the exception of the strong energy condition. Likewise, we prove a no-go theorem for conformally related regular black holes, which states that the four energy conditions can never be met in this class of black holes. In order to seek evidences for distinguishing regular black holes from singular black holes, we resort to analogue gravity and regard it as a tool to mimic realistic regular black holes in a fluid. The equations of state for the fluid are solved via an asymptotic analysis associated with a numerical method, which provides a modus operandi for experimental observations, in particular, the conditions under which one can simulate realistic regular black holes in the fluid.
Asynchronous axonal firing patterns evoked via continuous subthreshold kilohertz stimulation

Published: March 2023

Abstract

Objective. Transcutaneous electrical stimulation of peripheral nerves is a common technique to assist or rehabilitate impaired muscle activation. However, conventional stimulation paradigms activate nerve fibers synchronously with action potentials time-locked with stimulation pulses. Such synchronous activation limits fine control of muscle force due to synchronized force twitches. Accordingly, we developed a subthreshold high-frequency stimulation waveform with the goal of activating axons asynchronously. Approach. We evaluated our waveform experimentally and through model simulations. During the experiment, we delivered continuous subthreshold pulses at frequencies of 16.67, 12.5, or 10 kHz transcutaneously to the median and ulnar nerves. We obtained high-density electromyographic (EMG) signals and fingertip forces to quantify the axonal activation patterns. We used a conventional 30 Hz stimulation waveform and the associated voluntary muscle activation for comparison. We modeled stimulation of biophysically realistic myelinated mammalian axons using a simplified volume conductor model to solve for extracellular electric potentials. We compared the firing properties under kHz and conventional 30 Hz stimulation. Main results. EMG activity evoked by kHz stimulation showed high entropy values similar to voluntary EMG activity, indicating asynchronous axon firing activity. In contrast, we observed low entropy values in EMG evoked by conventional 30 Hz stimulation. The muscle forces evoked by kHz stimulation also showed more stable force profiles across repeated trials compared with 30 Hz stimulation. Our simulation results provide direct evidence of asynchronous firing patterns across a population of axons in response to kHz frequency stimulation, while 30 Hz stimulation elicited synchronized time-locked responses across the population. Significance. We demonstrate that the continuous subthreshold high-frequency stimulation waveform can elicit asynchronous axon firing patterns, which can lead to finer control of muscle forces.

Published: March 2023

Abstract
Iraqi Metakaolin was used to produce geopolymer mortar and concrete with high specifications. To convert Kaolin to Metakaolin, the De-hydroxylation process was carried out by burning Kaolin at 700°C. Metakaolin was crushed and ground by a ball mill to obtain the Metakaolin at the nanoscale. The large specific surface area of total nanoparticles gives unique properties during their interaction with an alkali-activated solution to form the geopolymer. Nano metakaolin geopolymer mortar mixtures were manufactured entirely according to specification ASTM C109/C109M-16a with different concentrations of alkaline solution (8 - 10 - 12 – 14) molarity. Through mortar test, it was noted the best result of geopolymer at 12 molarity, gives the advantage of dissolving alumina and silica nanoparticles to forming a geopolymer with high specifications. The highest rate of compressive strength of geopolymer mortar is 73 MPa. But in the geopolymer concrete mix with other nanomaterials replaced as a percentage by weight of the nano metakaolin binder, where incorporated (3%) nano-glass blended with (0.01%) carbon nanotube to observe the superior compressive strength reached 74.7 MPa. The effect of freezing and thawing has been, and no effect on compressive strength. During the water absorption test, observed that the absorbance is close to 1.7 %. The main benefit of the total binder nano metakaolin geopolymer is no heat treatment is used for the polymerization process and obtaining high specifications due to the effectiveness and high pozzolan effect of nanomaterials leads to improving compressive strength and other durability properties.

Authors: Hairi H M , Rosli M H , Mamat M H , Noor N H M , Supardan S N , Kamil S A 
Published: March 2023

Abstract
Optical Fiber Humidity Sensors (OFHSs) have attracted significant research interest due to their several advantages including small size, high durability and can withstand the extreme environment regardless of high temperature, high pressure and high electromagnetic radiation. In this study, the proposed sensors were built from standard single-mode silica fibers working at telecommunication wavelengths and exhibited very good humidity sensing characteristics. Single-mode optical fibers were coated with different dipping numbers (2, 4, 6 8, and 10 times) of polyvinyl alcohol (PVA) solution using a dip coating method. The sensing performance of uncoated and PVA-coated optical fiber sensors in terms of its sensitivity for various relative humidity (RH) percentages ranging from 40 to 90 % RH was monitored using Ocean Optics spectrometer. The intensity peaks of PVA-coated optical fibers were increased linearly with dipping numbers. The optimum sensing performance was observed for 10 times dipping number of PVA solution with the highest intensity of 4100 counts at 60 % RH and exhibits good repeatability with precision error values in the range of 0 to 2 %. Furthermore, the gap difference between intensity counts due to % RH changes could be clearly observed for 10 times dipping numbers. These reported results are important to enhance the performance of humidity sensor for sensing and monitoring purposes.

Published: March 2023

Abstract
The main focus in this study is to determine the stability of the plasma generated by a Dielectric Barrier Discharge (DBD) reactor in the presence and without glass beads as dielectric enhancement. The stability of plasma was determined based on plasma temperature which measured within plasma stream. The DBD plasma reactor was designed, fabricated and being operated in an open air system. Fiber Bragg grating (FBG) was used to measure the plasma temperature. The applied voltage was increased up to 8 kV to determine breakdown voltage and evaluate plasma stability with and without the presence of glass beads as dielectric enhancement. Experimental results revealed that plasma started to generate at applied voltage about 3.0 kV. Plasma formation found generated with stable at applied voltage 8 kV for both with and without the presence of glass beads. With the presence of glass beads, the plasma temperature found much higher about 180 °C compare with without glass beads which is about 90 °C, and yet the plasma generation is still stable.

Published: March 2023

Abstract
Image segmentation is a critical step in computer-aided diagnosis that could speed up Leukemia detection. Leukemia is a cancer of the blood that has a reputation for being particularly lethal. Based on the immunohistochemical method, the leukocytes can be manually counted in a stained peripheral blood smear image to detect Acute Lymphoblastic Leukemia (ALL). Regrettably, the manual diagnosis process takes about 3 to 24 hours to complete, which is insufficient. This paper introduced a new and straightforward ALL image segmentation approach based on color image transformation. First, Leukemia, ALL-IDB1, ALL-IDB2, and ALL image datasets were used in this paper. The Leukemia dataset includes 208 ALL-IDB1 and ALL-IDB2 images, while The ALL dataset has 3256 images. Next, we use the HSV model to transform ALL images. In addition, we modified the HSV model by pre-processing the saturation channel for better results. Then, the pre-processed images were segmented based on a fixed threshold. After that, various metrics are utilized to measure the output of the proposed method. Finally, the proposed methodology is compared to currently used benchmarks. The proposed method outperforms previous approaches regarding accuracy, specificity, sensitivity, and time. In addition, results show that the proposed technique improves performance measures significantly.
A new approach for DNA sequence analysis using multiwavelet transform (MWT)
Authors: Sakran Ammar AbdRaba , Hadi Suha M , Mahmoud Al-Jawher Waleed A 
Published: March 2023

Abstract
Finding the nucleotide sequence within a DNA (deoxyribonucleic acid) molecule is the process of DNA sequencing. The DNA of every organism is made up of a specific pattern of nucleotides. Scientists can compare the DNA of different organisms by sequence to understand how organisms are connected. Three different forms of DNA sequencing - fragment analysis, Next Generation Sequencing (NGS), and Sanger sequencing - enable many new applications that increase our knowledge of genomes. It significantly impacts how well we understand how the genome works. Finding the hidden structural information of DNA is an important task. This paper introduces Multi-Wavelet Transformation (MWT) for analysis of the sequence of the DNA symbols. The symbolic DNA sequence has four indicator sequences. The MWT assigned symbols to numbers based on DNA structure. It can change each channel’s weighting to optimize energy distribution over MWT output. Analysis of synthetic and actual DNA sequences allowed the researchers to evaluate how well the proposed MWT works. The results show that the MWT has a higher energy dispersion than the regular WT and the bionic wavelet transform (BWT). Future DNA sequence analyses should be able to discover hidden structural features using this MWT approach.
Semileptonic weak Hamiltonian to in momentum-space subtraction schemes

Published: March 2023

Abstract
The CKM unitarity precision test of the Standard Model requires a systematic treatment of electromagnetic corrections for semi-leptonic decays. Electromagnetic corrections renormalize a semi-leptonic four-fermion operator and we calculate the 𝒪(ααs
) perturbative scheme conversion between the

MS

¯

scheme and several momentum-space subtraction schemes, which can also be implemented on the lattice. We consider schemes defined by MOM and SMOM kinematics and emphasize the importance of the choice of projector for each scheme. The conventional projector, that has been used in the literature for MOM kinematics, generates an artificial QCD contribution to the conversion factor, which reflects in an unphysical dependence on the lattice matching scale. This can be traced to the violation of a Ward identity that holds in the case QED is neglected. We show how to remedy this by judicious choices of projector. The resulting Wilson coefficients (and operator matrix elements) have greatly reduced scale dependence.
Sterile neutrinos in light of the Cabibbo-angle anomaly
Authors: Kitahara Teppei , Tobioka Kohsaku 
Published: March 2023

Abstract
Based on recent developments in the lattice simulations and calculations of the radiative corrections to the charged-current interactions, the uncertainties for each component in the CKM matrix have been sophisticated. It is known that the first-row CKM unitarity is violated at about 3σ level, implying a 3σ level deviation from the standard model prediction. This new deviation is called Cabibbo-Angle Anomaly (CAA). These CKM components are mainly extracted from kaon, pion, and the superallowed beta decays. In this contribution, we point out that a MeV scale sterile neutrino can economically explain the CAA. We consistently investigate the sterile neutrino contributions to the kaon, pion, superallowed beta decays, and also the Fermi coupling constant.

Direct CP violation in K → ππ decay on the lattice with periodic boundary conditions
Authors: Tomii Masaaki 
Published: March 2023

Abstract
Following our recent publication on direct CP violation and the ΔI = 1/2 rule in K → ππ decay, which was made with G-parity boundary conditions, we revisit this problem with a conventional lattice setup employing periodic boundary conditions and two lattice spacings to check our previous result and to improve the precision. We show that the physical amplitude, which corresponds to an excited state in this case, can be obtained reliably with the Generalized Eigenvalue Problem (GEVP) method. Not only are periodic boundary conditions cheaper and allow the use of existing ensembles to take the continuum limit, but they provide a straightforward path to introduce electromagnetism and strong isospin symmetry breaking, which will be needed in the near future. In this article we show our preliminary results and discuss the prospect of the high-precision calculation of K → ππ decay with periodic boundary conditions.

Effect of low-energy neutrons on accidental counting rate in the KOTO experiment
Authors: Matsumura T 
Published: March 2023

Abstract
For further sensitivity improvement in the KOTO experiment, we studied the origin and mechanism of accidental hits of the VETO counters. A simulation study shows that a half of the counts of Front-Barrel (FB) VETO counter is stemmed from “delayed photons”, which is produced by the (n,γ) reaction due to the thermal neutrons moderated in the KOTO detector. A boron-carbide absorber is a possible candidate to suppress the delayed photons.

Baryon number violation from confining New Physics
Authors: Arun Mathew Thomas 
Published: March 2023

Abstract
The detection of neutron-antineutron oscillation will be a discovery of fundamental importance in particle physics and cosmology. Models predicting them, usually, assume weak couplings at the scale of the experiment, although Nature has been quite evasive regarding the issue. Acknowledging this, we discuss a new non-perturbative mechanism, generated by confining New Physics in a linear moose, resulting in low-energy baryon number violating effects within the reach of current terrestrial and Neutron Star measurements.
