Published: May 2024

Physics based tools and methods play an enormous role in understanding structural features and functions of viral particles along with their impact on the body. For example, X-ray crystallography utilizes electro-magnetic radiation to produce wavelength that can help to generate 3D detailed structure of the virus. Another technique used for obtaining structure information is the Cryo- electron microscopy. Cryo-EM is the electron microscopy method applied to sample cooled to very low temperature. Computed tomography (CT) imaging technology, widely known  as CT scan, use a narrow beam of X-ray quickly rotated around the patient to produce cross-sectional images or “slices” of the body. The George Washington university hospital utilized CT images to show the impact of COVID-19 on the lungs of a patient. A ventilator is required to strongly give adequate degrees of oxygen in blood. We learn about all of these physics-related methods and tools to fight SARS-CoV-2 and Covid-19 through UNO’s biomedical physics concentration. Medical physicists by diagnosing and treating patients and as biomedical specialists by designing and building biomedical equipment. Artificial intelligence, nanotechnologies, synthetic biology, drones, robots, Tele health technologies, open-source technologies and gene -editing are the application used in technologies to fight covid-19.

Authors: Meng Fan-Tsui , Jhuang Jing-Rong , Peng Yan-Teng , Chiang Chun-Ju , Yang Ya-Wen , Huang Chi-Yen , Huang Kuo-Ping , Lee Wen-Chung
Published: May 2024

Background

Lung cancer remains the leading cause of cancer-related mortality globally, with late diagnoses often resulting in poor prognosis. In response, the Lung Ambition Alliance aims to double the 5-year survival rate by 2025.

Objective

Using the Taiwan Cancer Registry, this study uses the survivorship-period-cohort model to assess the feasibility of achieving this goal by predicting future survival rates of patients with lung cancer in Taiwan.

Methods

This retrospective study analyzed data from 205,104 patients with lung cancer registered between 1997 and 2018. Survival rates were calculated using the survivorship-period-cohort model, focusing on 1-year interval survival rates and extrapolating to predict 5-year outcomes for diagnoses up to 2020, as viewed from 2025. Model validation involved comparing predicted rates with actual data using symmetric mean absolute percentage error.

Results

The study identified notable improvements in survival rates beginning in 2004, with the predicted 5-year survival rate for 2020 reaching 38.7%, marking a considerable increase from the most recent available data of 23.8% for patients diagnosed in 2013. Subgroup analysis revealed varied survival improvements across different demographics and histological types. Predictions based on current trends indicate that achieving the Lung Ambition Alliance’s goal could be within reach.

Conclusions

The analysis demonstrates notable improvements in lung cancer survival rates in Taiwan, driven by the adoption of low-dose computed tomography screening, alongside advances in diagnostic technologies and treatment strategies. While the ambitious target set by the Lung Ambition Alliance appears achievable, ongoing advancements in medical technology and health policies will be crucial. The study underscores the potential impact of continued enhancements in lung cancer management and the importance of strategic health interventions to further improve survival outcomes.
Development of a digital psychological therapy program for pediatric cancer patients (Preprint)
Authors: Hong Jiheun , Oh Hayoung
Published: May 2024

UNSTRUCTURED

Psychotherapy for cancer patients is currently gaining attention in South Korea. The fact that depression and anxiety disorders in cancer patients have been proven to worsen cancer prognosis has had a major impact on the surge in academic interest. In this regard, the Cancer Stress Clinic has been established at the Seoul Asan Medical Center, and the medical community has established a new field of psycho-oncology to study psychotherapy for cancer patients. Despite this interest, only 9% of Korean hospitals actually implement psychotherapy for cancer patients. In this study, we propose VR-based digital therapy as a way to deliver psychotherapy to more patients. In addition, we propose improving patients' understanding of therapy as a methodology for psychological stabilization. Since patients' distrust and nervousness about treatment are related to persistent psychological anxiety, learning breathing exercises for treatment understanding and pain relief are established as additional objectives.In this study, we selected pediatric cancer patients who are familiar with digital devices and require ongoing emotional support after treatment. Here is an overview of the proposed program Patients will be able to utilize VR devices to conduct counseling sessions with a digital human implemented in Unreal Engine. During the counseling process, the patient can select content such as art therapy, meditation content, and pain relief training. By working through the content, patients can improve their understanding of pain management methods and treatment, which can reduce anxiety. Finally, the program can be further developed to provide diagnostic reports to doctors.
Revealing The Economic Viability Of Railway Investments (Case Study: Restoring Your Railway Programme, United Kingdom)
Authors: Alfian Nur Zulhazmi , Muthohar Imam
Published: May 2024

The UK’s ”Restoring Your Railway” (RYR) programme aims to reopen abandoned railway infrastructure to foster local economic growth. However, since 2020, only 30% of RYR proposals have progressed, revealing challenges in the methodological approach, especially for projects introducing rail as a new mode. The current unimodal approach for estimating user benefits in such projects is considered inadequate. To address this, a Cost-Benefit Analysis (CBA) with improved methods for user benefit estimation has been conducted, compared with existing cases to determine if it results in a better Benefit-Cost Ratio (BCR). Historically, early appraisal methods relied on the Strategic Outline Business Case (SOBC), which took six months and incurred costs of approximately Rp. 1.5 billion. To expedite project delivery, sensitivity analysis explores circumstances under which RYR projects are socially justifiable across different Value for Money scenarios. Additionally, a comparative analysis is performed between the UK and Indonesian approaches. This study introduces a new CBA approach, focusing on user benefit estimation and conducting sensitivity analysis on key determinants. The mathematical CBA model, modified for the value of time and diversion factor, forms the basis for sensitivity analysis on BCR, travel time savings, capital and operational costs, diversion factor, and GDP growth. Testing the model against business cases reveals a 17-20% reduction in the required demand for the same BCR compared to conventional CBA approaches, suggesting the new method captures additional benefits related to mode shifts. Sensitivity analysis highlights circumstances under which railway projects are likely to deliver acceptable value for money, considering various BCR values. Total order indices show that operational costs contribute 40% to the model output, followed by capital costs and GDP growth rate at 29% and 25%, respectively. Surprisingly, the In-Vehicle Time (IVT) for trains has only a small contribution, ranging from 1.83% to 4%.
Radiation Observation Instruments Based on the Peltier Effect
Authors: Liu Yiya
Published: May 2024

Ionising radiation consists of three types of radiation, alpha beta gamma, which are invisible to the naked eye. In order to observe ionising radiation with the naked eye, the Wilson cloud chamber was invented. The operation of Wilson cloud chamber requires the use of a disposable cold source such as dry ice, which has the disadvantage of short operating time and releasing a large amount of greenhouse gases. The semiconductor cooling chip is a solid-state thermoelectric device using the Peltier effect, which does not release any greenhouse gases during the working process. This paper explores the design and fabrication of an all-solid-state-cooled Wilson cloud chamber based on the working principle of semiconductor refrigeration discs, and fabricates an engineering prototype by means of 3D printing-based technology.
A Study on the English Translation of Fond Memories of Peiping from the Perspective of Reception Aesthetics
Authors: Yang Huiyu , Bai Yangming
Published: May 2024

The prose Fond Memories of Peiping portrays the unique impression of Peijing of the Chinese writer Lao She, highlighting deep affection and attachment to his homeland, which is of high literary and aesthetic value. This paper discusses the application of reception aesthetics’ core concepts of “horizon of expectations”, “fusion of horizons” and “indeterminacy” in the translation of prose, which takes Mr. Zhang Peiji’s English translation of Fond Memories of Peiping as an example. It is found that Mr. Zhang Peiji’s employs amplification and free translation methods to deal with culture-loaded words and idioms to meet the readers’ expectations. Through the manipulation of rhetorical devices and the adaptation of sentence structures, the translated text is made more in line with the reading habits of the target language readers, thereby achieving “fusion of horizons”. Zhang Peiji demonstrates subjectivity in the translation process to deal with “indeterminacy” in the original text, which effectively preserves and conveys the aesthetic value of the original work.

Published: May 2024

Effective food packaging provides number of purposes. It functions as a container to hold and transport the food product, as well as a barrier to protect the food from outside contamination such as water, light, odours, bacteria, dust, and mechanical damage by maintaining the food quality. The package may also include barriers to keep the product's moisture content or gas composition consistent. Furthermore, convenience is vital role in packaging, and the desire for quick opening, dispensing, and resealing packages that maintain product quality until fully consumed is increasing. To facilitate trading, encourage sales, and inform on content and nutritional attributes, the packaging must be communicative. For storage of food there is huge scope for modified atmosphere packaging, intelligent packaging, active packaging, and controlled atmosphere packaging. Active packaging has a variety of uses, including carbon dioxide absorbers and emitters, oxygen scavengers, antimicrobials, and moisture control agents. Smart packaging is another term for intelligent packaging. Edible packaging, self-cooling and self-heating packaging, micro packaging, and water-soluble packaging are some of the advancements in package material.
La persistencia de los estereotipos de género sobre las competencias de liderazgo
Authors: Berings Dries , Deschacht Nick
Published: May 2024

Este artículo estudia los estereotipos de género sobre las competencias de liderazgo entre hombres y mujeres, y el efecto del pensamiento estereotipado sobre la autoestima de dichas competencias. Nos basamos en datos de encuestas originales que miden tanto el pensamiento estereotipado de género como la autoestima, sobre una extensa lista de 25 competencias de liderazgo. Nuestro principal hallazgo es que las actitudes estereotipadas de género tienen un efecto sustancial en la autoestima y que este efecto es mayor para las mujeres que para los hombres. También encontramos que los estereotipos más fuertes existen para las competencias en las que se considera que las mujeres son mejores (como empatizar); que tanto los hombres como las mujeres tienen estereotipos, aunque los estereotipos son más fuertes entre los hombres (especialmente para las competencias que están más estrechamente relacionadas con el liderazgo); que existen diferencias sustanciales de género en la autoestima sobre ciertas competencias específicas de liderazgo, pero no sobre la competencia general para liderar; y que las teorías implícitas del liderazgo están fuertemente relacionadas con los estereotipos de género (competencias que están más fuertemente relacionadas con el liderazgo, son también competencias de las que los encuestados consideran que los hombres son mejores en ello).

Comparative Analysis of Spiral Bevel Gear Pressure Angle for Off-Highway Vehicle Applications: Optimization of Performance and Durability
Authors: C Karthik
Published: May 2024

Abstract: This research paper presents a comparative analysis of different pressure angles in spiral bevel gears to determine their impact on performance and durability in off-highway vehicle applications, particularly in industries such as construction, mining, and agriculture. Through theoretical modeling, finite element analysis (FEA), and experimental testing, we investigate how varying pressure angles—specifically 20°, 22.5°, and 25°—influence key performance indicators such as load distribution, stress concentration, and wear characteristics under diverse operational conditions. Our findings indicate that higher pressure angles enhance load-carrying capacity and reduce gear size but introduce higher stress levels, potentially compromising gear durability. Conversely, lower pressure angles improve durability but may result in increased gear size and reduced load capacity. The optimization process involves balancing these trade-offs to identify the most suitable pressure angle for specific applications. This research provides comprehensive guidelines for selecting pressure angles in spiral bevel gears, aiding in the design of more robust and efficient transmission systems for off-highway vehicles, thereby benefiting gear manufacturers and designers in enhancing operational efficiency and lifespan.

Published: May 2024

Abstract: The early prediction and accurate diagnosis of diabetes are critical for effective disease management and treatment. This study presents a novel diabetes prediction model based on a Grasshopper Optimization Algorithm (GOA)-tuned Adaptive Neuro-Fuzzy Inference System (ANFIS). The proposed model aims to enhance accuracy in diabetes prediction by optimizing key parameters within the ANFIS framework using the GOA algorithm. Also, various other issues like complexity, dimensionality, overfitting and under-fitting are mitigated by implementing a hybrid Grey Wold optimization (GWO) and Fuzzy (F) based GWOF Feature selection technique. The efficacy of proposed approach is examined on one of the widely used diabetic datasets i.e., PIMA dataset. Simulations were carried out in MATLAB software under different metrics including accuracy (A), Precision (P), recall (R) and F1-measure (F1-M) on PIMA dataset. The results reveal that proposed GOA-tuned ANFIS model attained an accuracy of 96.22% on given dataset which is higher than standard Non-Linear, DWT, EMD, CNN-LSTM, and CNN-LSTM with SVM considerably.

Authors: Agudelo-Maldonado Dennis Valentina , Bayona-Torrado Yolmery , Pérez-Castro Karol Andrea , Sánchez-Perozo Mayra Alejandra
Published: May 2024

El trabajo de investigación se centra en el fenómeno del comercio informal en la ciudad de Cúcuta, se manifiesta como una respuesta palpable a los desafíos económicos que enfrentan diversos sectores de la sociedad. Es evidente que esta forma de comercio ha desempeñado un papel significativo en la generación de oportunidades laborales para un segmento considerable de la población. No obstante, junto con sus beneficios, también plantea importantes desafíos. Uno de los aspectos más notables es la creación de una competencia desigual en el mercado, dado que los comerciantes informales operan en un contexto diferente y, en ocasiones, sin las mismas regulaciones y obligaciones que los comerciantes formales. Además, el comercio informal a menudo genera problemas relacionados con la ocupación del espacio público, afectando la planificación urbana y la comodidad de los ciudadanos. En este contexto, la propuesta apunta a abordar estos problemas fundamentales a través de una estrategia que fomente la conciencia sobre los riesgos asociados con la informalidad en el comercio. Se pretende promover la transición hacia la formalización de estas actividades a través de la implementación de una guía educativa. Esta guía estaría diseñada para informar y asistir a los comerciantes informales en el proceso de transición hacia una operación comercial formal y legal. Es esencial reconocer la necesidad de simplificar los procesos administrativos gubernamentales relacionados con la formalización. Esto facilitaría y agilizaría la transición de los comerciantes informales hacia la legalidad, eliminando obstáculos y brindando incentivos claros para operar dentro de un marco legal. Además, la propuesta busca un cambio cultural en la percepción de los beneficios a largo plazo que conlleva la operación legal de un negocio. Se pretende inculcar una mentalidad que valore la legalidad empresarial, reconociendo los beneficios económicos y sociales que provienen de esta transición hacia la formalidad.
Diversity, equality, and inclusion: A case for public procurement bid disputes management in an emerging market
Authors: Nyathore Paul Mathenge , Wainaina Gituro , Awino Zachary Bolo , Kariuki James Thuo
Published: May 2024

Bid disputes arise when aggrieved bidders appeal decisions of procuring entities. It is through procurement appeals that issues of discrimination, inequality, and exclusion are challenged (Canayaz et al., 2022). However, the marginalized groups of youth, women, people living with disabilities, and micro, small and medium enterprises (MSMEs) rarely pursue this avenue of procurement justice. This is despite public procurement growing into an important avenue for helping governments achieve various development objectives (Organisation for Economic Co-operation and Development [OECD], 2013). The objective of this study was to assess diversity, equality, and inclusion (DEI) in the management of bid disputes in Kenya. Content analysis of all the bid dispute cases that were heard and determined by the Public Procurement Administrative Review Board (PPARB) between 2011 and 2020 was conducted. In addition, requests for review procedures and guiding laws were reviewed. Descriptive data analysis supported by deductive reasoning was thereafter conducted. It was established that the procurement appeals system in Kenya does not favor the disadvantaged categories of youth, women, people living with disabilities, and MSMEs thus promoting discrimination, inequality, and exclusion. In addition to contributing to the body of knowledge, this research proposes policy direction regarding the management of public procurement bid disputes in Kenya with a special focus on DEI.

In bacteria, faithful DNA segregation of chromosomes and plasmids is
mainly mediated by ParABS systems. These systems, consisting of a ParA
ATPase, a DNA binding ParB CTPase, and centromere sites parS,
orchestrate the separation of newly replicated DNA copies and their
intracellular positioning. Accurate segregation relies on the assembly
of a high-molecular-weight complex, comprising a few hundreds of ParB
dimers nucleated from parS sites. This complex assembles in a
multi-step process and exhibits dynamic liquid-droplet properties.
Despite various proposed models, the complete mechanism for partition
complex assembly remains elusive. This study investigates the impact of
DNA supercoiling on ParB DNA binding profiles in vivo, using the
ParABS system of the plasmid F. We found that variations in DNA
supercoiling does not significantly affect any steps in the assembly of
the partition complex. Furthermore, physical modeling, leveraging
ChIP-seq data from linear plasmids F, suggests that ParB sliding is
restricted to approximately 2-Kbp from parS, highlighting the
necessity for additional mechanisms beyond ParB sliding over DNA for
concentrating ParB into condensates nucleated at parS. Lastly,
explicit simulations of a polymer coated with bound ParB suggest a
dominant role for ParB-ParB interactions in DNA compaction within ParB
condensates.
Left Atrial Septal Pouch Thrombus: An Unusual Cause of An Embolic Stroke

Published: May 2024

A large proportion of ischemic strokes have an undetermined cause and
are considered “cryptogenic.” A left atrial septal pouch (LASP)
develops due to incomplete fusion of the septa primum and secundum,
forming a pocket at the interatrial septum. It can be a potential site
of blood stasis with resultant thrombus formation. LASP has a higher
prevalence among patients who present with cryptogenic stroke, but it is
rare to visualize a thrombus in the LASP. We present a case of stroke
with visualization of a LASP with in-situ thrombus confirming a
pathogenic role.
Functional traits and habitat types rather than elevation predispose an African cycad to pre-dispersal seed predations

The genus Encephalartos is entirely endemic to Africa. Like most cycad
species, the genus is at risk of extinction. One of the threats
jeopardizing the future of the genus is reproduction failure. Our
objective is to investigate what predisposes Encephalartos species to
reproduction failure. We collected functional traits of 430 individuals
of Encephalartos villosus, including pre-dispersal seed predation and
habitat types and elevation in Origi Gorge Nature Reserve in South
Africa. Then, we analysed our data by fitting a structural equation
model (SEM). Surprisingly, elevation does not predict pre-dispersal seed
predations, adding to the inconsistent effects of elevation on seed
predation. However, there was evidence of more predated seeds on plants
with more leaves, fitting the patterns of resource concentration
hypothesis which predicts more insect herbivores, particularly
specialist herbivores, where food resources (e.g., leaves, flowers,
fruits, and seeds) are abundant. We also found that more predated seeds
are in open habitats, perhaps mirroring the specialist feeding behaviour
of the weevil Antliarhinus zamiae feeding on the seeds of Encephalartos
spp. Furthermore, taller plants tend to bear more predated seeds,
potentially because taller plants are easy located by the weevil.
Finally, large canopy correlates negatively with predated seeds,
mirroring our finding of increased seed predation in open habitats. Our
SEM explains 67% of the variations in pre-dispersal seed predations,
suggesting that this metamodel provides insights into the predisposition
of cycad seed to predations. Since open habitats correlate with more
seed predation, we suggest that anthropogenic activities that contribute
to open forest must be avoided if we are to limit seed predations.

Saliva has emerged as a promising diagnostic resource due to its
accessibility, non-invasiveness, and repeatability, enabling early
disease detection and timely intervention. However, current studies
often overlook the distinction between whole saliva (WS) and cell-free
saliva (CFS). This study aims to compare the proteomic profiles of WS
and CFS, both with and without low-abundance proteins enrichment using
nanoparticles, employing DIA-MS technology. Our findings reveal a
substantial enhancement in the detectability of low-abundance proteins
in saliva with utilization of nanoparticles, enabling identification of
12%-15% low-abundance proteins previously undetectable in WS or CFS.
In total, 3817 saliva proteins were identified, with 3413 found in WS
and 2340 in CFS. More interestingly, we found that it wasn’t the
similarity of the samples that did the clustering, but rather it
depended more on the different detection methods and sample types. And
the predominant functions of the identified proteins in WS were related
to oxidative phosphorylation and neurodegenerations, whereas those in
CFS were primarily associated with nitrogen and glycosaminoglycan
metabolism. And both exhibited functions in immune response and
proteasome. This study represents the first comparison of WS and CFS,
providing valuable experimental evidence for guiding the selection of
research subjects in future salivomics studies.
Familial Hypercholesterolemia presenting with Acute Coronary Syndrome (NSTEMI)

Published: May 2024

Familial hypercholesterolemia (FH) is the most common metabolic disorder
and is inherited in an autosomal dominant fashion. FH presents with
xanthomas and early coronary artery disease, owing to relatively high
levels of low-density lipid-cholesterol (LDL-C) compared to
hypercholesterolemia without a genetic predisposition. The first
clinical manifestation of this condition could be an acute coronary
syndrome in undiagnosed and unsuspecting patient. Various clinical
criteria are available to make a diagnosis of FH and a clinician should
use the one which he is familiar with. Owing to very high LDL-C levels
patients often need multiple oral lipid lowering agents to achieve the
desired LDL-C goal. There are multiple novel parenteral lipid lowering
agents in offing and some are in pipeline with advantage of high potency
and weekly or monthly dosing. This case report emphasizes the importance
of FH screening and aggressive treatment to decrease morbidity and
mortality in the general population.

Let R be a ring and a, d1, d2 ? R. First, we obtain several equivalent
conditions for the equality aa?d1 = a?d2 a to hold, under the condition a ?
R?d1 ? R?d2 . Then, when a ? R??d1 ? R??d2 , the equality ama?d1 = a?d2 am
(m ? N) is also investigated by means of Drazin inverses. Next, some
characterizations for the invertibility of aa?d1 ? a?d2 a are obtained.
Particularly, a number of examples are given to illustrate our results.
Two algorithms for solving generalized coupled Sylvester tensor equations

Published: May 2024

In this paper, we consider the generalized coupled Sylvester tensor equations
by the tensor forms of the biconjugate A-orthogonal residual and the
conjugate A-orthogonal residual squared algorithms. With the absence of
round-off errors, we show that our methods converge to the exact solution
group within finite steps when they are consistent. Finally, we provide some
numerical examples to demonstrate the effectiveness of the proposed methods,
including when testing the algorithms by color image restoration problems
and randomly generated data.
