Emergent Quantum Mechanics – How the Classical Laws Can Replicate the Quantum Harmonic Oscillator
Authors: van Holten Theo 
Published: September 2023

Emergent Quantum Mechanics (Em.QM) is defined here as the attempt to bridge the gap between quantum and classical mechanics, and to restore causality to the atomic world. An example described in the paper shows how a conspiracy of the classical laws produces a replica of the quantum harmonic oscillator. This is achieved using a droplet model of electrons, obeying Newton/Einstein dynamics in combination with Maxwell’s electromagnetic laws.

A concise sketch of the droplet theory precedes the sections on the harmonic oscillator. This summary also briefly mentions other successes of the droplet theory, such as the derivation of the fundamental quantum laws \(p=\frac{h}{\lambda}\) and \(E=h.\nu\) with a practically correct numerical value of Planck’s constant h. Although these subjects were already addressed in earlier publications about Em.QM, recently simpler and more transparent derivations were found and are reported here.

Finally, the achievements of Em.QM until now are reviewed. Em.QM does not compete with conventional QM: the latter will always be superior for performing actual calculations, whereas Em.QM is concerned with possible interpretations of quantum phenomena. An assessment is given of the present status of Em.QM in this perspective.
Asymptomatic Apical Hypertrophic Cardiomyopathy: Case Report and Review of Literature
Authors: Akhil Mehrotra  , Anurag Mehrotra  , Mohammed Shaban  , Shubham Kacker  
Published: September 2023

Apical hypertrophic cardiomyopathy (AHCM) is a known entity since its first introduction by Sakamoto and Yamaguchi. However, unlike classical hypertrophic cardiomyopathy (HCM), it is less explored in terms of its associated diagnosis and long-term outcomes. Given the increased availability and utilization of ultra-sophisticated cardiac imaging modalities, AHCM will be increasingly recognized as a distinct, clinically significant variant of classical HCM. It is associated with a wide spectrum of presentation ranging from asymptomatic course with incidental findings on imaging to rarely being associated with ventricular arrhythmias, syncope and sudden cardiac death (SCD). Contrast echocardiography is the most effective and diagnostic study when performed in the right setting with high suspicion on clinical and typical electrocardiogram (ECG) findings. Cardiac magnetic resonance imaging (CMR) has an equal diagnostic yield as a contrast echocardiogram. We are presenting a unique case report of a 57-year old gentleman with asymptomatic AHCM which was distinctly delineated after utilizing contrast tuned imaging (CnTI) echocardiography sans administration of intravenous contrast agents. This is a first case report of AHCM portrayed by this ingenious technology.

Infeasible Desires of Women in Girish Karnad’s Selected Plays
Authors: Prabhakar Madella  , Brij Govind  
Published: September 2023

This article is a humble attempt to search the identity of women in the patriarchal society prevailing in India. The condition of women in India has undergone several alterations since past millennia. During the Vedic time, women enjoyed a higher status and were extolled to the heights of Heaven by epitomising her as Goddess. Gradually with the passage of time women lost their status and dignity. She is regarded as an abla, a weak and helpless lady who depends upon man for her existence and sustenance. Indian Literature viewed women as role bound possession whose sacrifices preserved the sanctity and the well being of the family. Literature has always been ambivalent in its representation of women. Writers observed that women had become a heated argument and they started portraying them in their works. They drew inspirations from the real life incidents, which talked about liberating the images. This article traces the paradigm shift where women emerge despite all obstacles to hold her identity in personal and professional life. This paper aims at portraying, the women is no more an accessory to man rather she is a companion, a life partner who is equal to men in all aspects.

Spatio-angular filter (SAF) imaging device for deep interrogation of scattering media
Authors: Pandya Aditya , Schelkanova Irina , Douplik Alexandre 
Published: September 2023

<p>Optical microscopy is limited to shallow interrogation depths as high-resolution imaging in scattering media is challenging. Current methods require complex and expensive experimental setup or suffer from low resolution. Through gating of photons exiting the scattering media using a restricted numerical aperture (NA) fiber optic plate (FOP), we establish a novel spatio-angular filter imaging device that allows deeper imaging in scattering media. Using dilutions of Intralipid (1-4 v/v%) and a USAF resolution target, it is shown that by reducing the NA of the FOP from 0.55 to 0.17, the interrogation depth improves ~2 times using trans-illumination.</p>

Feasibility of Specular Reflection Imaging for Extraction of Neck Vessel Pressure Waveforms
Authors: Saiko Gennadi , Burton Timothy , Douplik Alexandre 
Published: September 2023

<p>Cardiovascular disease (CVD) is a leading cause of death worldwide and was responsible for 31% of all deaths in 2015. Changes in fluid pressures within the vessels of the circulatory system reflect the mechanical function of the heart. The jugular venous (JV) pulse waveform is an important clinical sign for assessing cardiac function. However, technology able to aid evaluation and interpretation are currently lacking. The goal of the current study was to develop a remote monitoring tool that aid clinicians in robust measurements of JV pulse waveforms. To address this need, we have developed a novel imaging modality, Specular Reflection Vascular Imaging (SRVI). The technology uses specular reflection for visualization of skin displacements caused by pressure pulsations in blood vessels. SRVI has been tested on 10 healthy volunteers. 10-seconds videos of the neck illuminated with a diffuse light source were captured at 250 fps. SRVI was able to identify and discriminate skin displacements caused by carotid artery and jugular vein pulsations to extract both carotid artery and jugular vein waveforms, making them easier to be visualized and interpreted. The method provided a 6-fold improvement in signal strength over a comparator remote PPG dataset. The current pilot study is a proof-of-concept demonstration of the potential of Specular Reflection Vascular Imaging for extraction of JV pulse waveforms.</p>

Microvascular contrast enhancement in optical coherence tomography using microbubbles
Authors: Assadi Homa , Demidov Valentin , Karshafian Raffi , Douplik Alexandre , Vitkin I. Alex 
Published: September 2023

<p>Gas microbubbles (MBs) are investigated as intravascular optical coherence tomography (OCT) contrast agents. Agar + intralipid scattering tissue phantoms with two embedded microtubes were fabricated to model vascular blood flow. One was filled with human blood, and the other with a mixture of human blood + MB. Swept-source structural and speckle variance (sv) OCT images, as well as speckle decorrelation times, were evaluated under both no-flow and varying flow conditions. Faster decorrelation times and higher structural and svOCT image contrasts were detected in the presence of MB in all experiments. The effects were largest in the svOCT imaging mode, and uniformly diminished with increasing flow velocity. These findings suggest the feasibility of utilizing MB for tissue hemodynamic investigations and for microvasculature contrast enhancement in OCT angiography.</p>

Contrast Ratio during Visualization of Subsurface Optical Inhomogeneities in Turbid Tissues: Perturbation Analysis
Authors: Saiko Gennadi , Douplik Alexandre 
Published: September 2023

<p>Visualization and monitoring of the capillary loops and microvasculature patterns in dermis and mucosa are of interest for various clinical applications, including early cancer and shock detection. We developed an approach for the assessment of the contrast ratio during the visualization of subsurface optical heterogeneities. Using the diffuse approximation and perturbation analysis, we considered light absorption heterogeneities as negative light sources. We estimated the contrast ratio as a function of the surface layer's optical properties for diffuse and collimated wide beam illumination. Based on findings, we formulated several practical suggestions: a) proper selection of camera (with maximum dynamic range) is of paramount importance, b) narrow-band illumination is more efficient than white light illumination, and c) use of collimated light provides up to 60% improvement in contrast vs. diffuse illumination. Obtained results can be used for the optimization of imaging techniques </p>

<p>Developing minimally invasive methodologies for imaging of internal organs is an emerging field in the biomedical examination research. This paper introduces a new multi-functional microendoscope device capable of imaging of internal organs with a minimal invasive intervention. In addition, the developed microendoscope can also be employed as a monitoring device for measuring local hemoglobin concentration in blood stream when administrated into a blood artery. The microendoscope device has a total external diameter of only 200 μm and can provide high imaging resolution capability of more than 5,000 pixels. The device can detect features with a spatial resolution of less than 1 μm. The microendoscope has been tested both in-vitro as well as in-vivo in rats presenting a promising and powerful tool as a high resolution and minimally invasive imaging facility suitable for previously unreachable clinical modalities.</p>

Decoupling and tuning the light absorption and scattering resonances in metallic composite nanostructures
Authors: Danan Yossef , Ramon Yehonatan , Azougi Jonathan , Douplik Alexandre , Zalevsky Zeev 
Published: September 2023

<p>Utilizing the localized surface plasmon resonance (LSPR) effect of metallic nanoparticles enables their usage as contrast agents in a variety of applications for medical diagnostics and treatment. Those applications can use both the very strong absorption and scattering properties of the metallic nanoparticle due to their LSPR effects. There are certain applications where domination of the scattering over absorption or vice versa would be an advantage. However, the scattering and absorption resonance peaks have practically the same spectral location for solid noble metal nanoparticles at a certain domination of one over the other. In this paper we present gold nanoparticles coated with silicon that switches the order between the scattering and the absorption magnitude at the resonance peak by up to 34% in scattering-absorption ratio and tune the plasmon resonance over the spectrum by up to 56nm. This is obtained by modifying the refractive index of the silicon coating of the nanoparticle by illuminating it with a pumping light due to the plasma dispersion effect in silicon.</p>

Number symbols are processed more automatically than nonsymbolic numerical magnitudes: Findings from a Symbolic-Nonsymbolic Stroop task
Authors: Sokolowski Moriah , Hawes Zachary , Leibovich-Raveh Tali , Ansari Daniel 
Published: September 2023

<p>Are number symbols (e.g., 3) and numerically equivalent quantities (e.g., •••) processed similarly or distinctly? If symbols and quantities are processed similarly then processing one format should activate the processing of the other. To experimentally probe this prediction, we assessed the processing of symbols and quantities using a Stroop-like paradigm. Participants (N<sub>Study1</sub> = 80, N<sub>Study2</sub> = 63) compared adjacent arrays of symbols (e.g., 4444 vs 333) and were instructed to indicate the side containing <em>either</em> the greater quantity of symbols (nonsymbolic task) or the numerically larger symbol (symbolic task). The tasks included congruent trials, where the greater symbol and quantity appeared on the same side (e.g. 333 vs. 4444), incongruent trials, where the greater symbol and quantity appeared on opposite sides (e.g. 3333 vs. 444), and neutral trials, where the irrelevant dimension was the same across both sides (e.g. 3333 vs. 333 for nonsymbolic; 333 vs. 444 for symbolic). The numerical distance between stimuli was systematically varied, and quantities in the subitizing and counting range were analyzed together and independently. Participants were more efficient comparing symbols and ignoring quantities, than comparing quantities and ignoring symbols. Similarly, while both symbols and quantities influenced each other as the irrelevant dimension, symbols influenced the processing of quantities more than quantities influenced the processing of symbols, especially for quantities in the counting rage. Additionally, symbols were less influenced by numerical distance than quantities, when acting as the relevant and irrelevant dimension. These findings suggest that symbols are processed differently and more automatically than quantities.</p>

Published: September 2023

The coronavirus pandemic overwhelmed many countries and a shortage of testing kits and centers for exposed patients worsens the situation in most countries. These have prompted the need to quickly predict COVID-19 in patients and stop the spread of the virus. In this research, we present a method for predicting COVID-19 based on symptoms, and to make this system efficient, the dataset was obtained from Afriglobal Laboratory Nigeria, and preprocessing and feature extraction were done on the dataset. Three classifiers, logistic regression, support vector machines, and hybridization of the logistic regression and support vector machines were used to train the data. The test data were evaluated against the model, and the research found that the performance analysis values for accuracy, precision, recall, and F1score for logistic regression (LR) are 91%, 91%, 95%, and 93%, for Support Vector Machines (SVM), 94%, 93%, 100%, and 96% and for the Hybridized model (LR+SVM) are 95%, 94%, 98%, and 96%. To get the parameters needed for the performance evaluation of the classifiers, the confusion matrix method was employed. In comparison to existing methods and studies, the hybridized system performs better than LR and SVM models. As a result, the hybridized model can accurately predict Covid-19.

In this work, a new scheme is generated from the extended 3–point super class of block backward differentiation formula for integrating stiff IVP and the proposed method is subjected to convergence test. The proposed scheme is found to be zero stable, consistent and of order 5. Thus, possess all the required criteria for convergence. The scheme can approximate the values of three points at a time per integration step. The scheme maintained the same technique of co-opting a stability control parameter () in the formula and by adjusting its value within the interval , more A-stabled schemes can be generated. However, this research considers and arrived at zero and A– Stabled method, capable of solving any stiff IVPs. Hence, the proposed convergent scheme can be used for integrating stiff IVPs and archives accuracy of scale error and less executional time.

The higher level of human activities has resulted in several forms of anthropogenic activities with diverse adverse effects on human and environmental sustainability. The traditional means of handling xenobiotics pollutants are no longer sustainable due to the high cost involved, complex procedures and demanding regulatory requirements. Bioremediation using fungi (mycoremediation) is now recognized as an efficient and workable biotechnological tool that effectively employ fungal enzymes via the process of absorption and mineralization to get rid of contaminants. Cytochrome P450s (CYPs) are diverse and unique gene families with varying degree of complexities in the eukaryotes. CYPs mainly utilize molecular oxygen to modify substrate conformation, thereby establishing a mechanism of action for achieving their important physiological and ecological processes. Xylariaceae belongs to the main and highly diversified families of filamentous Ascomycota; it plays an important role as saprotrophs of wood, soil, litter and dung. Genome-wide annotation analysis was carried out to explore the possibility of utilizing the CYPs of Xylaria sp. for achieving mycoremediation. The evolutionary analysis has divided the 214 Xylaria CYPs into fifteen (15) clades. The CYPs were categorized into forty-seven (47 clans) and eighty-six (86) families. MEME suite identified ten (10) conserved motifs. The gene structural investigation reveals high dynamic intron-exon organization. Most of the CYPs have been predicted to be localized in the endoplasmic reticulum. This study therefore calls for deeper exploration of the Xylaria sp and its high potential for application in bioremediation for the degradation of environmental contaminants.
