Published: October 2022

Highlights. Early atherosclerotic changes in the abdominal aortic wall and common iliac arteries in patients without clinical manifestations of critical atherosclerotic stenosis of the lower extremity arteries were studied using contrast enhanced magnetic resonance imaging. A method for quantitative characterization of the accumulation of paramagnetic contrast in the abdominal aortic wall and common iliac arteries is presented.Aim. To study the pattern of early atherosclerotic lesions of the abdominal aortic wall and common iliac arteries in patients without clinical manifestations of critical atherosclerotic stenosis of the lower extremity arteries using paramagnetic contrast enhancement (CE-) MRI.Methods. The retrospective study included 36 patients (25 men, 11 women) who underwent MRI of the lumbar spine with CE, without signs of atherosclerosis of the lower extremities. Subsequently, 2.5 and 4 years after CE-MRI, two patients developed acute leg ischemia and required vascular surgeries. At the time of the study, both had higher levels of C-reactive protein in the blood (6.3 mg/L and 5.9 mg/L, while the other patients had <4.2 mg/L). MRI included T2 – and T1-weighted spin-echo scans (T2-w and T1-w) in the axial and sagittal planes, before and in 10-15 minutes after contrast injection. The index of enhancement (IE) of T1-w was calculated based on the ratio of mean intensities of the region of arterial wall over aorta and iliac arteries in CE-MRI and pre-contrast MRI: IE = Int.T1–w. CE / Int. T1–w pre-contrast.Results. Depending on the IE of the abdominal aortic wall in CE-MRI, patients were divided into three groups: group 1 (n = 11) with IE ≤1.05; group 2 (n = 16) with 1.05 <IE ≤1.15; group 3 (n = 9) with IE >1.15. The aortic IE in all three groups was 1,03 (1,01;1,03); 1,10 (1,09;1,15); 1,36 (1,16;1,40) respectively (p<0.001). The thickness of the abdominal aortic wall progressively increased moving up the group 1, while statistically significant differences were found only between the groups 1 and 3, and the groups 2 and 3 (p<0.001). There were no differences in the wall thickness of the common iliac arteries and the diameter of all vessels studied between the groups. Two patients from the group 3 later presented with acute limb ischemia.Conclusion. The state of the abdominal aortic wall and common iliac arteries should be evaluated, and IE of T1-w should be calculated when performing CE-MRI examination of the area of the descending aorta to assess pathological neoangiogenesis as the most important component of atherogenesis.

Published: October 2022

Due to the COVID-19 pandemic, face-to-face interactions are still not permitted for the teaching and learning process. This condition has led to changes to the existing learning method to willy-nilly switch from conventional classes to what is called distance learning. Distance learning is referred to as online learning as its implementation requires Internet media that accommodate lecturers to interact with students online. The success of implementing online learning contributes to the learner’s satisfaction within the process of teaching and learning. This study used three applications—Camtasia video creator, YouTube, and Google Classroom—to assess how learners perceive the synchronous and asynchronous learning they have received. This study used a hybrid technique, combining a Google Form online survey with qualitative analysis of the respondents' answers. 52 students from the English Literature Department's Intermediate English Grammar Class served as the research participants. The findings indicate that the majority of students react well to the adoption of asynchronous learning when those three programs are used. The flexibility of access and timing is the most important and beneficial benefit. The integration between those three applications in conducting asynchronous learning is expected to provide a new perspective on implementing technology in English language teaching.

Abstract
Geothermal exploration poses as the stage with the highest risk of failure, due to its high technical uncertainty and limitations of expense. A substantial part of it is locating prospective reservoir, where in the conventional approach of physics-based modelling, geothermal data limitations are prone to be ignored with simplifying assumptions. In a stage when achieving technical accuracy while also maintaining cost-effectiveness is very crucial, this work is proposed to maximize both aspects by leveraging Machine Learning (ML) models to address the shortcomings of physics-based model and significantly cut down the cost incurred in the exploration stage.
This paper will discuss the proposed novel methodology of ML utilization in generating high resolution temperature-at-depth map used to locate prospective geothermal reservoir, with less time and resource than the conventional approach. The result and impact are studied and evaluated using the dataset of the UTAH Forge project.

Abstract
Background
MammaPrint (MMP) helps clinicians identify the ideal time for adjuvant treatment for patients with early HR+/HER2- breast cancer. We aimed to externally validate a nomogram designed to predict probability of low risk of MMP results and to evaluate the difference in survival outcome between two groups stratified by nomogram score.
Methods
In this retrospective cohort study, we evaluated 172 patients from Asan Medical Center, Seoul, Korea, who underwent breast cancer surgery and MMP during 2020–2021. We internally validated the nomogram by calculating the area under the curve (AUC) and using calibration. With the data of 1,835 T1-3N0-1M0 HR+/HER2- patients from Asan Medical Center during 2010–2013, we compared the disease-free survival (DFS), overall survival (OS), and breast cancer-specific survival (BCSS) rates by Kaplan-Meier analysis between the two groups divided by nomogram total point (TP) for externally validation.
Results
The AUC calculated by internal validation of 172 patients was 0.73 (95% confidence interval [CI], 0.77–0.87). The discrimination and calibration of the prediction model were satisfactory following external validation. The high-risk and low-risk groups had different 5-year OS (97.9% vs 98.1%, p = 0.056), DFS (98.6% vs 99.4%, p = 0.008), and BCSS rates (98.6% vs 99.4%, p = 0.002).
Conclusions
For treatment decision-making among clinically high-risk patients with HR+/HER2- and node-positive disease, the nomogram showed satisfactory performance in predicting patients with low genomic risk. Survival outcome significantly differed between two groups divided by nomogram TP. More studies are needed to validate this model in international cohorts and large prospective cohorts from other institutions.
In-silico design of a multi-epitope recombinant vaccine against SARS-CoV-2 targeting the receptor-binding domain
Authors: Pande Harshawardhan , Aranha Michelle 
Published: October 2022

Abstract
The COVID-19 pandemic caused by the SARS-CoV-2 virus has posed several challenges in the development of efficacious epitope-based vaccines. While multiple bioinformatic studies have attempted to predict epitopes, they have focused on the whole spike protein without considering antibody-mediated enhancement or Th-2 immunopathology, and some have missed some important but less antigenic epitopes in the receptor binding domain. Therefore, this study used in-silico methods to design and evaluate a potential multiepitope vaccine that specifically targets the receptor-binding domain due to its critical function in viral entry. Immunoinformatic tools were used to specifically examine the receptor-binding domain of the surface glycoprotein for suitable T cell and B cell epitopes. The selected 5 B cell and 8 T cell epitopes were then constructed into a subunit vaccine and appropriate adjuvants along with the universal immunogenic PADRE sequence were added to boost efficacy. The structure of the vaccine construct was predicted through a de-novo approach and molecular docking simulations were performed which demonstrated high-affinity binding to TLR 5 receptor and appropriate HLA proteins. Finally, the vaccine candidate was cloned into an expression vector for use as a recombinant vaccine. Similarities to some recent epitope mapping studies suggest a high potential for eliciting neutralizing antibodies and generating a favorable overall immune response.
Topological breakdown influenced by both disorder and
electron-electron interaction probed by real-time bulk and edge
measurement

Abstract
Quantum properties associated with topology [1, 2] are distinguishable in their immunity to a range of variations. The extent of this range, which is found to vary ubiquitously in real systems, marks a robustness fundamental to all topological orders. The underlying mechanisms that potentially obscure topological protection are usually associated with effects of disorders either inherent to the systems or imperfections introduced during sample fabrications [3]. Suppression of the influence of disorders is an essential challenge facing realistic precision quantum applications. So far, relevant works concentrate mostly on the dissipationless edge states (i.e. in the integer quantum Hall effect (IQHE) [4, 5]) in the context of the ability of sustaining the absence of backscattering [6]. The findings of the edge effects [7] alone, however, are insufficient to address the more general phenomena of topological breakdown which necessarily involves the bulk effects. In this study, simultaneous measurements of the bulk and edge responses are carried out independently in an IQHE, hosted in a Corbino two-dimensional system, brought to the verge of a topological breakdown. Accurately measured insulating and conducting responses reveal exceptional topological robustness in a strongly correlated limit where the cause of the breakdown is identified as back-scatterings arising between dissipationless current paths of opposite chirality facilitated by rare local resonant tunnelings. A unique "staircase" bulk feature, captured in real-time correspondence with the emergence of edge dissipation and deviation from Hall quantization, indicates a dielectric reconstruction effect influenced by enhanced impurity screening due to strong electron-electron interaction. These findings provide insight on suppressing disorder effects as an important means of reaching topological robustness.
Massive and massless plasmons in germanene nanosheets
Authors: Pisarra Michele , Gomez Cristian Vacacela , Sindona Antonello 
Published: October 2022

Abstract
Atomically thin crystals may exhibit peculiar dispersive electronic states equivalent to free charged particles of ultralight to ultraheavy masses.
A rare coexistence of linear and parabolic dispersions yields correlated charge density modes exploitable for nanometric light confinement.
Here, we use a time-dependent density-functional approach, under several levels of increasing accuracy, from the random-phase approximation to the Bethe-Salpeter equation formalism, to assess the role of different synthesized germanene samples as platforms for these plasmon excitations.
In particular, we establish that both freestanding and some supported germenene monolayers can sustain infrared massless modes, resolved into an out-of-phase~(optical) and an in-phase~(acoustic) component.
We further indicate precise experimental geometries that naturally host infrared massive modes, involving two different families of parabolic charge carriers.
We thus show that the interplay of the massless and massive plasmons can be finetuned by applied extrinsic conditions or geometry deformations, which constitutes the core mechanism of germanene-based optoelectronic and plasmonic applications.
