Published: September 2023

To increase the detectability of breast cancer, recent efforts have been made in the field of grating-based phase-contrast computed tomography, which provides additional information about the refractive index decrement introduced by the sample. Whereas this signal shows an increased soft-tissue contrast, the implementation for polychromatic sources is still tied to higher doses, preventing medical application on patients. To lower the dose, we introduce the self-supervised deep learning network Noise2Inverse into the grating-based phase-contrast computed tomography field and compare its results with other denoising methods, namely the Statistical Iterative Reconstruction, Block Matching 3D, and Patchwise Phase Retrieval. Before the comparison, the behavior of Noise2Inverse parameters on the phase-contrast results are evaluated. We show that Noise2Inverse delivers superior denoising results with respect to the investigated image quality metrics. Its application allows the increase of resolution while maintaining a good contrast-to-noise ratio. This could enable grating-based phase-contrast computed tomography to outperform conventional absorption-based computed tomography in dose-relevant applications.
Single-cell sequencing reveals the immune landscape of breast cancer patients with brain metastasis
Authors: Zhou Huaping
Published: September 2023

Breast cancer, cancer with the highest incidence rate worldwide, is also the most common cause of cancer death for women in all countries. Among them, brain metastasis (BrM) is a characteristic of a severely poor prognosis for breast cancer. Due to the unique anatomy of brain metastases, the understanding of the tumor immune microenvironment (TME) of BrM from breast cancer is limited, which hinders our diagnosis and treatment of breast cancer patients.

In this study, we used single-cell RNA sequencing (scRNA-seq) to characterize immune cells in the cerebrospinal fluid (CSF) of BrM patients to describe the immune landscape of BrM. We identified 9 cell subtypes: T cells, Tregs, MonoMacs, Macs, TAMs, Myeloid cells, DCs, Endo_Fibs and Glioblastals from CSF samples and analyzed their functions in the TME. In addition, we classified T cell, macrophage and DC subclusters by UMAP analysis and compared the differential genes and biological processes of each subcluster with changes in prognosis. Finally, we also analyzed cell-cell interactions among cell subclusters and their differences.

As our research focuses on the tumor immune microenvironment of brain metastasis, we believe that our research will be attractive not only to cancer immunologists but also to the interdisciplinary readership of Cancer Science.

Sub-domain Model for Induction Motor with More Accurate Realization of Tooth-Saturation
Authors: Kumar Rajendra
Published: September 2023

Incorporation of magnetic saturation and its aftereffects have been challenging for sub-domain based analytical electric motor models. The proposed model utilizes the direct phenomenal impact of magnetic saturation on spatial variation of the core's permeability to formulate the effective tooth width. Implementation of the proposed method does not need an additional domain or magnetic vector-potential dependent term to include the saturation and hence, provides an efficient approach. The developments derived from the proposed method are seen in better estimation of motor's power factor, breakdown torque, and additional iron loss due to tooth pulsation and surface eddy currents. Prediction capability of the model is demonstrated with the experimental and finite element results of an 11 kW, four-pole induction motor for a wide range of operation.

Navigating the Quantum Computing Threat Landscape for Blockchains: A Comprehensive Survey
Authors: Khodaiemehr Hassan , Bagheri Khadijeh , Feng Chen
Published: September 2023

Quantum computers pose a significant threat to blockchain technology’s security, which heavily relies on public-key cryptography and hash functions. The cryptographic algorithms used in blockchains, based on large odd prime numbers and discrete logarithms, can be easily compromised by quantum computing algorithms like Shor’s algorithm and its future qubit variations. This survey paper comprehensively examines the impact of quantum computers on blockchain security and explores potential mitigation strategies. We begin by surveying the existing literature on blockchains and quantum computing, providing insights into the current state of research. We then present an overview of blockchain, highlighting its key components and functionalities. We delve into the preliminaries and key definitions of quantum computing, establishing a foundation for understanding the implications on blockchain security. The application of blockchains in cybersecurity is explored, considering their strengths and vulnerabilities in light of evolving quantum computing capabilities. The survey focuses on the quantum security of blockchain’s fundamental building blocks, including digital signatures, hash functions, consensus algorithms, and smart contracts. We analyze the vulnerabilities introduced by quantum computers and discuss potential countermeasures and enhancements to ensure the integrity and confidentiality of blockchain systems. Furthermore, we investigate the quantum attack surface of blockchains, identifying potential avenues for exploiting quantum computing to strengthen existing attacks. We emphasize the need for developing quantum-resistant defenses and explore solutions for mitigating the threat of quantum computers to blockchains, including the adoption of quantum and post-quantum blockchain architectures. By examining vulnerabilities and discussing mitigation strategies, we aim to guide researchers, practitioners, and policymakers in developing robust and secure blockchain systems capable of withstanding advancements in quantum computing technology.
Distributed Observer-Based Dynamic Event-Triggered Control of Multi-Agent Systems with Adjustable Inter-Event Time
Authors: Wang Zeyuan , Chadli Mohammed
Published: September 2023

This paper proposes a dynamic event-triggered control strategy for the leader-following multi-agent control under directed topology.  A synthesis approach combining distributed controllers and observers design is developed under a dynamic sampling scheme, and only local information is required for each agent to implement the proposed method. The control protocol incorporates model-based estimation and clock-like auxiliary dynamic variables to prolong the inter-event time as long as possible.  Sufficient conditions for leader-following consensus control are established by linear matrix inequalities, and an explicit inter-event time is given to enable flexible tuning. Due to the carefully selected Lyapunov function, the proposed method exhibits significant advantages over the dynamic event-triggered control methods described in the existing literature. Compared to the existing static event-triggered strategy, the proposed approach significantly reduces the utilization of communication resources while preserving asymptotic convergence to the state consensus.  The validity and effectiveness of the proposed theoretical results are demonstrated by comparative simulations.

19/1/2020 to investigate the effect of addition of monensin at levels of 15, 30 and 45 mg/kg

concentrate on growth performance of Awassi lambs. First treatment in which lambs were fed

concentrate diet without addition of monensin was considered the control treatment. Sixteen male

Awassi lambs were used with an average weight of 24.85 and 4-6 months of age. The lambs were

randomly distributed to the experimental treatments, four lambs per each using the individual

feeding in the cages. The concentrate diet was offered at a level of 2.75% of the body weight at 2

meals, morning and evening meals, while the ground wheat straw was offered at free choice.

Results revealed no significant effect of level of monensin on pH values, whereas ruminal ammonia

concentrations were significantly decreased (P˂0.05) from 7.54 in the control treatment to 6.08 and

6.45 mg/100 ml due to addition of monensin at levels of 30 and 45 mg/kg. Moreover, addition of

monensin at a level of 30 mg/kg concentrate diet significantly increased (P˂0.05) ruminal

concentration of total volatile fatty acids to 13.76 as compared with 10.99 mM/100 ml for control

treatment. Concentrations of all rumen fermentation characteristics were significantly affected

Authors: Aziz Rawa Abdul Redha , Mohameed Elaf Sameer
Published: September 2023

Objective(s): P. mirabilis is considered as extensive drug resistant pathogen in many studies as it

can resist complex antibiotic regimes, such pathogen can be threat to public health, especially when

it has the ability to produce biofilm. Therefore, biofilm production was characterized among XDR

P. mirabilis local isolates in this research.

Material and Methods: 100 P. mirabilis isolated from wound infections from patients admitted to

Baghdad hospitals. They were identified using biochemical test and Vitek2 system. The MIC test

for antibiotic sensitivity was done by Vitek 2 automated system. Biofilm production was identified

phenotypically by twitching motility test, scanning electron microscope, and microtiter plate assay.

Results: It could be revealed that 8/100 isolates were MDR, 90/100 isolates were XDR and pan

drug resistance level was shown in only two isolates. 80% of isolates had motile ability through

twitching assay, and scan electron microscope study revealed that 76% of XDR isolates could

produce different stages of biofilm on coverslip placed in MacConkey broth. Microtiter plate assay

revealed 81% of XDR isolates were biofilm producers.

Conclusion: it could be concluded that extensive drug resistant P. mirabilis can produce biofilm

hence resist several important antibiotics; making treatment of infection among wounded patients is

such a challenge in many hospitals in Baghdad.

Published: September 2023

Background/Objectives: The aim of this study is to develop an experiential upcycling DIY kit using Subtraction Cutting, with the goal of promoting sustainable living for consumers during a time when environmental issues are increasingly important. Methods: As a theoretical study, this research examines the current state of sustainable clothing and the design methods of Zero Waste fashion through previous studies. For the practical study, Subtraction Cutting is selected as a technique that can be easily applied by ordinary consumers. Six experiential upcycling clothing kits are developed, with two kits for each of the three main techniques. The participants use a mix of materials, including their own used clothing, waste sheets, and spare fabrics, for the project. Results: The clothing items, including women's sleeveless top, jacket, vest, and skirt are mixed and matched with various materials. This kit is intended for time-limited experiential events for the general public and is designed for simple production. The focus is on enhancing sustainability not only by recycling clothes but also by extending the life of garments through shape deformation, utilizing the features of the Subtraction Cutting design. Conclusion/Implications: This study developed a clothing upcycling kit with enhanced sustainability, using Subtraction Cutting, that can be easily attempted by general consumers. The kit utilizes participants' used clothing, which could extend the life of the product. However, further research is needed to simplify the process and enable shape changes.

Published: September 2023

Background/Objectives: This study aims to determine the accessibility status of convenience stores from the perspective of manual wheelchair users (MWUs) and develop accessibility maps. Methods: In March 2022, a checklist developed by the researchers was employed to evaluate the entry and indoor space driving accessibility status of 62 convenience stores located in three dongs around the Chungbuk National University in Cheongju, and accessibility maps were developed based on that evaluation results. Results: The major findings are as follows. First, only 9.7% of the cases were found to have entrances where “MWUs can enter by him/herself,” while 14.5% had entrances where “MWUs can enter with insignificant assistance from others.” Second, only 3.2% of the cases had an indoor space where “MWUs can move around as is,” while 40.3% were found to have an indoor space where “MWUs can move around if the current shelf positions were adjusted.” Third, only one case out of the 62 cases was found to have both an entrance where “MWUs can enter by him/herself” and indoor spaces where “MWUs can move around as is.” Accessibility maps were developed considering the evaluation results of entry and indoor space driving accessibility. Conclusion/Implications: The level difference at an entrance exceeding 2 cm must be eliminated by installing a ramp with a slope less than 1/12 so that MWUs can enter without others’ assistance. Moreover, for a smooth indoor driving of MWUs, the spacing of shelves must be planned to be 0.9 m or wider from the preplanning stage or adjusted afterward.
The Impact of Haptic Mental Imagery Induced by Virtual Reality Interactivity on Dual Shopping Values
Authors:   Chungbuk National University, Research Institute of Human Ecology, Park Hyun Jung , Kim Eun Young
Published: September 2023

Background/Objectives: This study investigated the factors that drive the dual shopping values of consumers in virtual reality (VR) fashion store environments, focusing on the role of haptic mental imagery as a mental simulation. It examined how perceived interactivity can enhance haptic mental imagery and increase the vividness of overall mental images, ultimately leading to an increased evaluation of utilitarian and hedonic shopping values. Methods: A professional research company recruited 330 participants in their 20s and 30s. Participants experienced a VR fashion store to browse items they were interested in purchasing, after which they responded to questionnaires online. A total of 319 responses were used for further analysis. Structural equation modeling (SEM) with AMOS 23.0 was employed to test the hypotheses and multi-group comparisons. Results: Interactivity increased the participants’ haptic mental imagery and the vividness of their overall mental images. Haptic mental imagery helped enhance perceived imagery vividness. Both imagery-related variables had positive effects on the two shopping values. Differences in shopping orientation and gender were also observed in the relations among variables. Conclusion/Implications: This research provides insights into the impact of interactivity and the role of haptic mental imagery and vivid imagery in shaping VR store consumers’ shopping values.

Published: September 2023

Background/Objectives: As part of a larger study on predicting the mental health status of the disadvantaged using digital biomarkers, this study investigated the relationship of digital biomarkers (e.g., amount of physical activity, smartphone overuse, and sleeping time collected via smartphones) with the personal happiness of the disadvantaged. Furthermore, it suggests application points for housing welfare field practice. Methods: Using the Dr FoRest smartphone application, this study collected data on five types of digital biomarker (i.e., GPS, GYRO, DATA, TOUCH, and SLEEP) from 192 participants recruited from two public permanent apartment complexes in November 2022. In addition, it conducted a questionnaire survey, including the Happiness Scale and sociodemographic information. We analyzed the relationship between digital biomarkers and personal happiness using a series of statistical analyses, including bivariate correlation and multiple regression analyses. Results: The major findings are as follows. First, digital biomarkers can predict happiness with relatively high explanatory power. Second, the study observed a tendency in which happiness increased with the increase in walking and sufficient sleep and the decrease in smartphone use. Third, the majority of the sociodemographic characteristics (e.g., gender, receipt type, disability status, degree of disability, and household size), except for age group, were not significantly associated with personal happiness. Conclusion/Implications: First, a system that can extend the use of digital biomarkers needs to be established. Second, investing in and expanding programs or facilities that can naturally increase physical activity and reduce smartphone use are necessary measures for enhancing personal happiness. Finally, improving quality of sleep through efforts to mediate or solve this issue by providing customized counseling programs or mediating relationships with neighbors are favorable interventions given the influence of sleep conditions on personal happiness.
