Multispectral Imaging Method in Laparoscopy
Authors: Yang Xin 
Published: March 2024

Introduction. At present, video data acquired in narrow spectral bands are widely used to improve the efficiency of diagnostics in various medical fields, laparoscopy in particular. Conventional laparoscopy uses images obtained in the white light. Images obtained in the visible range suitably depict the color and textural features of tissues. However, it is difficult for a physician to use visible images for distinguishing between lesion areas and normal tissues, largely due to their proximity in color and texture. The efficiency of lesion detection can be improved using fluorescence images, which clearly differentiate lesion areas from normal tissues. However, the use multispectral data implies the need to present the images obtained both in the white and fluorescence light to the physician. In this paper, we propose an image composition method based on visible and fluorescence images, which facilitates their analysis by physicians. A distinctive feature of the method is the use of CIEDE 2000 metric for image fusion, which takes the properties of human vision into account.Aim. Development of a method for multispectral data visualization, which provides a physician with an image that combines white light data and a color-highlighted area of lesions.Materials and methods. The proposed method consists of the following steps: preprocessing of images obtained in visible and fluorescence light; segmentation of the lesion area in the fluorescence images; generation of a pseudo-color image of the segmented lesion area; and fusion of the pseudo-color image with the image obtained in the white light.Results. The proposed method forms an image that includes an image of the operation area obtained in the white light and a separated lesion area based on fluorescence information in the near infrared range. The image composite takes the properties of human vision into account. An experimental study of the method was carried out on actual laparoscopic images, involving endoscopists who were experts in subjective evaluation of video images. The method of paired comparisons was used to evaluated the presented images. The majority of experts preferred the fused image formed by the proposed method to those visualized simultaneously in the white and fluorescence light.Conclusion. The developed method ensures generation of images with an increased diagnostic value.
Research into the Impact of Phase Shifter Failures on the Characteristics of Slotted Waveguide Array Antenna
Authors: Bibarsov M. R. 
Published: March 2024

Introduction. Currently, the impact of phase shifter (PS) failures on the characteristics of phased antenna arrays, slotted waveguide array antenna (SWAA) in particular, represents a significant problem. A review of publications shows that insufficient attention has been paid to PS failures.Aim. To investigate the characteristics of a SWAA in the event of PS failures, when their phase takes a value equal to zero instead of the required value.Materials and methods. The methods of statistical modeling methods were used to study the impact of failures on SWA characteristics. Calculations were carried using the Mathcad 15 software package.Results. An algorithm for statistical modeling of the impact of PS failures on SWAA characteristics is proposed. A relationship that connects the radiation pattern with the volume of the statistical sample and the number of failed PSs is given. The malfunctions of emitters from 5 to 35 out of 50 elements were studied. Changes in the following characteristics were obtained: standard deviation – from 0.064 to 0.18, radiation pattern width – from 8 to 18 %, the level of side lobes – from 13 to 59 %, radiation power – from 0.9 to 0.3.Conclusion. The results obtained can be used in radio-electronic systems with antenna arrays at the stage of their development. Future work will address PS failures with phases being established randomly and with random values, as well as the case of PS failures where power does not pass into the emitter. Another important direction concerns compensation of distortions resulting from failures of antenna elements.

Published: March 2024

Introduction. Safety issues of railway transport are inevitably connected with the condition of railway tracks and railway wheels. Various defects, such as irregularities of the railway track, may lead to emergencies and incidents. Therefore, it is important to measure and calculate short and impulse irregularities. A joint analysis of vibration acceleration signals is needed in order to study the types and size of railway track irregularities.Aim. Development of an algorithm for irregularity search based on accelerometer readings with the vertical measurement axis.Materials and methods. The research encompassed wavelet transformation and wavelet-based signal processing including discrete-time signal processing and continuous wavelet processing. In addition, time-frequency analysis based on Fourier transform and continuous wavelet scalogram was used. These methods provide for time-frequency localization for irregularity detection and measurement.Results. Algorithms for vibrational signal processing using the continuous and discrete-time wavelet transform are proposed. The results show that the discrete wavelet transform is effective for multiresolution and multiband analysis, and continuous wavelet transform and wavelet scalogram allows extraction of irregularities and determination of their parameters. The relative error for irregularity depth was improved by 18 %, and the absolute error for irregularity length determinations was reduced by 7 times.Conclusion. Application of the discrete Fourier transform and Fourier spectrogram provides for fine resolution in the frequency domain. However, separation of signal components in the time-frequency domain is impeded. The continuous-time wavelet transform ensures sufficient resolution in the low-frequency domain for component localization and visualization of irregularities.
A Compensator Microelectromechanical Acceleration Transducer with a Piezoelectric Sensing Element and Optical Reading

Published: March 2024

Introduction.Modern mobile control objects require the use of highly sensitive transducers of motion parameters, e.g., acceleration, with a wide measurement range. Increased sensitivity to measured parameters can be achieved by using precision optics, e.g., based on the tunneling effect. However, operating ranges of induced movements are less than a micrometer, which creates difficulties in positioning the sensing element. In order to improve manufacturability, to extend the measurement range and to reduce errors of acceleration transducers with optical tunneling, compensation circuits with a piezoelectric actuator as an active sensor can be used.Aim.To extend the measurement range of microelectromechanical acceleration transducers through the use of an integrated approach, including the introduction of a compensation circuit for sensor movements based on the inverse piezoelectric effect and detection of these movements by optical means.Materials and methods.An approach to compensating sensor movements is proposed. This approach consists in using a bimorph piezoelectric plate as an inertial element. The use of optical reading of sensor sub-micrometer displacements is considered.Results.A block scheme and a functional scheme of a compensator micro-opto-electromechanical acceleration transducer with a bimorph piezoelectric sensing element are developed. Deformations in the sensing element under the influence of accelerations (up to 100 m/s2) and compensation voltages, whose amplitude does not exceed several volts, are investigated to ensure the possibility of using the optical tunneling effect in the proposed transducer.Conclusion.A mathematical model of the transducer was developed and studied. A 2.5-fold increase in the measurement range was achieved. It was shown that the introduction of compensation feedback does not decrease the permissible frequency range of measured accelerations.
Three Buddhist Distinctions of Great Consequence for Cross-Cultural Philosophy of Personal Identity
Authors: Panaioti Antoine 
Published: March 2024

<p>This paper seeks to lay down the theoretical groundwork for the emergence of holistic cross-cultural philosophical investigations of personal identity ¾ investigations that approach the theoretical, phenomenological, psychological, and practical-ethical dimensions of selfhood as indissociable. My strategy is to discuss three closely connected conceptual distinctions that the Buddhist approach to personal identity urges us to draw, and a lucid understanding of which is essential for the emergence of appropriately comprehensive and thus genuinely cosmopolitan discussions at the cross-road between Western and Buddhist philosophical traditions. The first, primary distinction is that between the “visceral sense of self” (VSS) and the “substance view of self” (SVS). This in turn gives rise to two derivative distinctions, namely between “harbouring VSS” and “believing SVS”, and between “overcoming VSS” and “rejecting SVS”. After discussing these distinctions, I consider and respond to three philosophical objections to features of Buddhist approach to selfhood that are thrown into sharper relief when attention is paid to these three distinctions. I then discuss some of the ways the foregoing may inform research in cross-cultural philosophy of personal identity. This discussion focuses on: (1) the primacy of the first-person stance in matters of personal identity; (2) the relationship between numerical identity and narrative identity; (3) interdisciplinarity in the study of selfhood; and (4) personal identity and egoism.</p>

Illusion Or Delusion? A Re-Examination of Buddhist Philosophy of Personal Identity
Authors: Panaioti Antoine 
Published: March 2024

<p>In this article, I argue against the conventional view that Buddhist philosophy of personal identity regards the self as an illusion. Critically engaging the work of Miri Albahari, I defend the view that it is instead centered around the properly diagnostic claim that the overwhelming majority of human beings suffer from a <em>delusion</em> concerning the nature of the self. In the central section of the paper, I draw from contemporary work in philosophy of psychiatry to gain clarity on what delusions are and how they are distinct from illusions. On the <em>narrative theory of delusions</em> I thence develop, delusions are best understood as <em>faulty and harm-inducing self-referential narrative constructions</em>. Buddhist views on human beings’ confusion concerning the self, I then submit, consist of the diagnosis of a delusion in precisely this sense. At the end of the article, I argue that in addition to its intrinsic merits this interpretation has the added advantage of bringing into sharper focus the irreducibly therapeutic character of Buddhist philosophy of personal identity, and I discuss the implications of this for future cross-cultural research on the problem of selfhood.</p>

Abstract

Serratia marcescens is a global opportunistic pathogen. In vitro cytotoxicity of this bacterium is mainly related to metalloprotease serralysin (PrtS) activity. Proteolytic capability varies among the different isolates. Here, we characterized protease production and transcriptional regulators at 37°C of two S. marcescens isolates from bronchial expectorations, HU1848 and SmUNAM836. As a reference strain the insect pathogen S. marcescens Db10 was included. Zymography of supernatant cultures revealed a single (SmUNAM836) or double proteolytic zones (HU1848 and Db10). Mass spectrometry confirmed the identity of PrtS and the serralysin-like protease SlpB from supernatant samples. Elevated proteolytic activity and prtS expression were evidenced in the HU1848 strain through azocasein degradation and qRT-PCR, respectively. Evaluation of transcriptional regulators revealed higher eepR expression in HU1848, whereas cpxR and hexS transcriptional levels were similar between studied strains. Higher eepR expression in HU1848 was further confirmed through an in vivo transcriptional assay. Moreover, two putative CpxR binding motifs were identified within the eepR regulatory region. EMSA validated the interaction of CpxR with both motifs. The evaluation of eepR transcription in a cpxR deletion strain indicated that CpxR negatively regulates eepR. Sequence conservation suggests that regulation of eepR by CpxR is common along S. marcescens species. Overall, our data incorporates CpxR to the complex regulatory mechanisms governing eepR expression and associates the increased proteolytic activity of the HU1848 strain with higher eepR transcription. Based on the global impact of EepR in secondary metabolites production, our work contributes to understanding virulence factors variances across S. marcescens isolates.

Abstract

Salmonella enterica is a common pathogen in humans and animals that causes food poisoning and infection, threatening public health safety. We aimed to investigate the genome structure, drug resistance, virulence characteristics, and genetic relationship of a Salmonella strain isolated from patients with food poisoning. The pathogen strain 21A was collected from the feces of patients with food poisoning, and its minimum inhibitory concentration against commonly used antibiotics was determined using the strip test and Kirby-Bauer disk methods. Subsequently, WGS analysis was used to reveal the genome structural characteristics and the carrying status of resistance genes and virulence genes of strain 21A. In addition, an MLST-based minimum spanning tree and an SNP-based systematic spanning tree were constructed to investigate its genetic evolutionary characteristics. The strain 21A was identified by mass spectrometry as S. enterica, which was found to show resistance to ampicillin, piperacillin, sulbactam, levofloxacin, and ciprofloxacin. The WGS and bioinformatics analyses revealed this strain as Salmonella Enteritidis belonging to ST11, which is common in China, containing various resistance genes and significant virulence characteristics. Strain 21A was closely related to the SJTUF strains, a series strains from animal, food and clinical sources, as well as from Shanghai, China, which were located in the same evolutionary clade. According to the genetic makeup of strain 21A, the change G > A was found to be the most common variation. We have comprehensively analyzed the genomic characteristics, drug resistance phenotype, virulence phenotype, and genetic evolution relationship of S. Enteritidis strain 21A, which will contribute towards an in-depth understanding of the pathogenic mechanism of S. Enteritidis and the effective prevention and control of foodborne diseases.

Abstract
Hydrocarbon constituents of petroleum are persistent, bioaccumulated, and bio-magnified in living tissues, transported to longer distances, and exert hazardous effects on human health and the ecosystem. Bioaugmentation with microorganisms like bacteria is an emerging approach that can mitigate the toxins from environmental sources. The present study was initiated to target the petroleum-contaminated soil of gasoline stations situated in Lahore. Petroleum degrading bacteria were isolated by serial dilution method followed by growth analysis, biochemical and molecular characterization, removal efficiency estimation, metabolites extraction, and GC-MS of the metabolites. Molecular analysis identified the bacterium as Bacillus cereus, which exhibited maximum growth at 72 hours and removed 75% petroleum. Biochemical characterization via the Remel RapID™ ONE panel system showed positive results for arginine dehydrolase (ADH), ornithine decarboxylase (ODC), lysine decarboxylase (LDC), o-nitrophenyl-β-D-galactosidase (ONPG), p-nitrophenyl-β-D-glucosidase (βGLU), p-nitrophenyl-N-acetyl-β-D-glucosaminidase (NAG), malonate (MAL), adonitol fermentation (ADON), and tryptophane utilization (IND). GC-MS-based metabolic profiling identified alcohols (methyl alcohol, o-, p- and m-cresols, catechol, and 3-methyl catechol), aldehydes (methanone, acetaldehyde, and m-tolualdehyde), carboxylic acid (methanoic acid, cis,cis-muconic acid, cyclohexane carboxylic acid and benzoic acid), conjugate bases of carboxylic acids (benzoate, cis,cis-muconate, 4-hydroxybenzoate, and pyruvate) and cycloalkane (cyclohexene). It suggested the presence of methane, methylcyclohexane, toluene, xylene, and benzene degradation pathways in B. cereus.

Published: March 2024

Introducción: en el ámbito de la clínica veterinaria, la esterilización se muestra como la cirugía de mayor frecuencia en gatas, no solo por su papel en la prevención de patologías del aparato reproductor, sino también por su contribución a la reducción del riesgo de contagio de enfermedades de transmisión sexual. En este contexto, el presente estudio se enmarca en el dinámico panorama de la medicina veterinaria, caracterizado por una revolución impulsada por avances tecnológicos. La investigación propuso la implementación de la pinza bipolar estilo bayoneta del Electrocauterio LED SPA SURTRON 160, Código 10100.30, de origen italiano. El objetivo central consistió en evaluar el impacto del tratamiento con dicha pinza bipolar en la Ovariectomía (OVE) en gatos domésticos (Felis catus). La metodología empleada abordó la comparación de dos técnicas quirúrgicas en un grupo de 30 pacientes felinos, divididos de manera homogénea. El grupo A, sometido a OVE, fue tratado mediante sutura absorbible de ácido poliglicólico, mientras que el grupo B fue sometido al mismo procedimiento, pero utilizando la pinza bipolar. Este enfoque metodológico riguroso buscó proporcionar una evaluación comprehensiva del efecto del tratamiento con la pinza bipolar en comparación con la técnica convencional de sutura absorbible. Resultados. Al trabajar con una muestra homogénea de pacientes felinos, se logró obtener un conjunto uniforme de datos. Los resultados indican que la cirugía de Ovariectomía (OVE) realizada con la pinza bipolar requiere significativamente menos tiempo en comparación con la técnica convencional de OVE, según el análisis de la prueba T de Student. En cuanto al dolor, no se observaron diferencias estadísticamente significativas entre ambas técnicas; sin embargo, se registró una menor intensidad del dolor en el grupo tratado con la pinza, según los resultados del análisis de Kruskal-Wallis. En conclusión, se infiere que la aplicación de la pinza en la OVE en gatas es recomendable, ya que no solo se traduce en una reducción significativa del tiempo quirúrgico, sino que también se muestra como una técnica confiable. Estos hallazgos respaldan la viabilidad y eficacia del uso de la pinza bipolar en este procedimiento específico, sugiriendo su consideración como una opción preferente en la práctica clínica veterinaria.
