Published: July 2022

Applications of X-ray computed tomography (CT) for porosity characterization of engineering materials often involve an extended data analysis workflow that includes CT reconstruction of raw projection data, binarization, labeling and mesh extraction. It is often desirable to map the porosity in larger samples but the computational challenge of reducing gigabytes of raw data to porosity information poses a critical bottleneck. In this work, we describe algorithms and implementation of an end-to-end porosity mapping code that processes raw projection data from a synchrotron CT instrument into a porosity map and visualization in the form of triangular face mesh. Towards this objective, we report the development of a novel subset reconstruction scheme for X-ray CT using filtered backprojection and a convolutional neural network that allows us to reconstruct arbitrarily-shaped subsets of a tomography object. We build upon this scheme to implement the complete code for porosity mapping. The code first detects possible voids by performing a coarse reconstruction on down-sampled projections and then improves the shape of those voids with higher detail offered by reconstructing selected subsets from the original raw data. We report measurements of the time taken by this code to perform complete processing from raw data to a triangular face mesh for several visualization scenarios on a single highperformance workstation equipped with GPU. We show that we can now visualize local porosity within a 8 gigavoxel CT volume (12 gigabytes raw data) within 1 to 2 minutes and a 64 gigavoxel CT volume (100 gigabytes of raw data) within 3 to 7 minutes.
Energy-Efficient Data Collection and Resource Allocation in Age-Aware IoV

Published: July 2022

The emergence of Internet of Vehicles (IoV) has facilitated many attractive vehicular applications that require massive sensed data and timely data analysis. Data collection and resource allocation are critical issues in IoV for timely data processing in dynamic network environments. However, the energy consumption of IoV infrastructure and vehicles pose challenges to developing sustainable vehicular communication and networking infrastructure. Moreover, the communication and computing resources are generally insufficient to support the transmission and analysis of the excessive data. Vehicular data are often updated periodically, which makes much of which outdated, or useless for vehicular applications, and thus leads to large latency and tremendous energy consumption. To this end, age of Information (AoI) has been introduced as a novel metric to characterize data freshness. Satisfying the state update AoI constraint is of great significance to guarantee the freshness of the IoV system. In this paper, we design a sampling strategy with responsive transmission and computing (e.g., no waiting latency), and investigate an energy minimization problem under peak AoI constraints in age-aware vehicular networks. We decouple the problem as a minimum set cover problem, and a convex problem, and propose a joint sampling selection and resource allocation (JSRA) algorithm to obtain the approximate optimal solution. We evaluate the proposed sampling selection and resource allocation strategy and JSRA algorithm by experiments on the simulation of urban mobilty (SUMO). Numerical results show that the proposed sampling strategy and algorithm outperform existing methods in terms of energy consumption, especially for the scenario with dense vehicles and pedestrians.
Robust Long-Term Hand Grasp Recognition With Raw Electromyographic Signals Using Multidimensional Uncertainty-Aware Models
Authors: Lin Yuzhou , Palaniappan Ramaswamy , De Wilde Philippe , Li Ling
Published: July 2022

Hand grasp recognition with surface electromyography (sEMG) has been used as a possible natural strategy to control hand prosthetics.

However, effectively performing activities of daily living for users relies significantly on the long-term robustness of such recognition, which is still a challenging task due to confused classes and several other variabilities.

We hypothesise that this challenge can be addressed by introducing uncertainty-aware models because the rejection of uncertain movements has previously been demonstrated to improve the reliability of sEMG-based hand gesture recognition.

With a particular focus on a very challenging benchmark dataset (NinaPro Database 6), we propose a novel end-to-end uncertainty-aware model, an evidential convolutional neural network (ECNN), which can generate multidimensional uncertainties including vacuity and dissonance, for robust long-term hand grasp recognition.

To avoid heuristically determining the optimal rejection threshold, we examine the performance of misclassification detection in the validation set.

Extensive comparisons of accuracy under the non-rejection and rejection scheme are conducted when classifying 8 hand grasps (including rest) over 8 subjects across proposed models.

The proposed ECNN is shown to improve the recognition performance, achieving an accuracy of 52.44% without the rejection option and 83% under the rejection scheme with multidimensional uncertainties, which significantly improves the current state-of-the-art (SoA) by 5.72% and 13.19%, respectively.

Furthermore, its overall rejection-capable recognition accuracy remains stable with only a small accuracy degradation after the last data acquisition over 3 days.

These results show the potential design of a reliable classifier that yields accurate and robust recognition performance.
A ±0.5-mV-Minimum-Input DC-DC Converter with Stepwise Adiabatic Gate-Drive and Efficient Timing Control for Thermoelectric Energy Harvesting
Authors: Carlson Eric , Smith Joshua
Published: July 2022

This paper presents a step-up DC-DC converter that uses a stepwise gate-drive technique to reduce the power FET gate-drive energy by 82%, allowing positive efficiency down to an input voltage of ±0.5 mV—the lowest input voltage ever achieved for a DC-DC converter as far as we know. Below ±0.5 mV the converter automatically hibernates, reducing quiescent power consumption to just 255 pW. The converter has an efficiency of 63% at ±1 mV and 84% at ±6 mV. The input impedance is programmable from 1 Ω to 600 Ω to achieve maximum power extraction. A novel delay line circuit controls the stepwise gate-drive timing, programmable input impedance, and hibernation behavior. Bipolar input voltage is supported by using a flyback converter topology with two secondary windings. A generated power good signal enables the load when the output voltage has charged above 2.7 V and disables when the output voltage has discharged below 2.5 V. The DC-DC converter was used in a thermoelectric energy harvesting system that effectively harvests energy from small indoor temperature fluctuations of less than 1°C. Also, an analytical model with unprecedented accuracy of the stepwise gate-drive energy is presented. 
A Comprehensive Exploration of Product Description Ranking
Authors: Guo Tong
Published: July 2022

In this paper, we study the personalized ranking problem for item's recommendation text (product description). Item's recommendation text is the sentence that describe the item highlights for user decision (such as buy or click). The recommendation texts is shown under the item, and we also call them rec-texts. One item has multiple rec-texts, and different rec-texts have different affect for user decision. So the problem is to capture the user preference for each item's rec-texts and to personalized display. In this paper, we study multiple methods to train a model which learn the user preference scores for each item's rec-texts. The online experimental results demonstrate our methods work.
Nucleotide tetramers TCGA and CTAG: viral DNA and the genetic code (hypothesis)
Authors: Filatov F. P.
Published: July 2022

Introduction. The published and our own data show that CTAG and, to a lesser extent, TCGA tetra-nucleotides have significantly lower concentrations in frequency profiles (FPs) of herpesvirus DNAs compared to other complete, bilaterally symmetrical tetra-nucleotides.The aim of the study is to present a comparative analysis of CTAG and TCGA tetra-nucleotide FPs in viral DNAs.Materials and methods. We have analyzed FPs and other characteristics of the two above tetramers in DNAs of at least one species of viruses of each genus (or each subfamily, if the classification into genera was not available), complying with the size limit requirements (minimum 100,000 base pairs) — a total of more than 200 species of viruses. The analysis was performed using the GenBank database.Results. Two groups of characteristics of TCGA and CTAG tetramers have been described. One of them covers the results of the FP analysis for these tetranucleotides in viral DNAs and shows that DNAs with GC:AT 2 are characterized by nCGn FP symmetries while these symmetries are frequently distorted in nTAn FP due to CTAG underrepresentation. The other group of tetramer characteristics demonstrates differences in their FPs in complete viral DNAs and in their genomes (a coding part, which can reach 80% in some studied viruses, thus making the analysis of their DNAs more significant than the analysis of DNAs of cellular live forms) and suggests that these tetramers may have participated in the origin of the universal genetic code.Discussion. Assumedly, the genetic code started evolving amid C+G prevailing in "pre-code" DNA polymers; then the initial code forms evolved further to their final structure where TCGA and CTAG tetramers hold a central position, encapsulating the previous stages of this evolution. The nCGn FP symmetries typical of the "complete" DNA of Herpes simplex viruses disappear in the sequence of the second codon letters of the genome of these viruses, implying that their functions differ from functions of other letters and emphasizing the reasonableness of presenting the genetic code as a calligram where the second line is not symmetrical.

Experiencias de la disidencia sexual y la disidencia de género en colegios bogotanos: el lugar de los docentes de la población LGBTIQ y las opiniones de la comunidad escolar
Authors: Ramírez-Rincón Michael Eduardo , Velasco López Gloria Susana
Published: July 2022

En este artículo se presentan algunos de los resultados más representativos de una investigación doctoral desarrollada durante el año 2021. Debido a las expresiones de violencia, acoso y discriminación que aún experimentan las personas de la población LGBTIQ en los colegios bogotanos, se consideró pertinente comprender las afectaciones de las dinámicas escolares cotidianas sobre las experiencias de disidencia sexual y de género de profesores homosexuales, lesbianas y transgénero cuyos relatos biográficos se contrastaron con las narrativas grupales de padres de familia, estudiantes y docentes desde un enfoque cualitativo-hermenéutico. Los resultados indican que los discursos y prácticas escolares relacionados con la sexualidad y el género están determinados por referentes heteronormados cuyo efecto sobre las experiencias de la disidencia sexual y de género de los docentes de la población LGBTIQ al interior de los colegios bogotanos es problemático, de ahí que estos educadores, en la mayoría de los casos, prefieran mantener privada su orientación sexual diversa o identidad de género no normativa.

Higgledy-Piggledy Sets in Projective Spaces of Small Dimension
Authors: Denaux Lins
Published: July 2022

This work focuses on higgledy-piggledy sets of $k$-subspaces in $\text{PG}(N,q)$, i.e. sets of projective subspaces that are 'well-spread-out'. More precisely, the set of intersection points of these $k$-subspaces with any $(N-k)$ subspace $\kappa$ of $\text{PG}(N,q)$ spans $\kappa$ itself.

We highlight three methods to construct small higgledy-piggledy sets of $k$-subspaces and discuss, for $k\in\{1,N-2\}$, 'optimal' sets that cover the smallest possible number of points.

Furthermore, we investigate small non-trivial higgledy-piggledy sets in $\text{PG}(N,q)$, $N\leqslant5$. Our main result is the existence of six lines of $\text{PG}(4,q)$ in higgledy-piggledy arrangement, two of which intersect. Exploiting the construction methods mentioned above, we also show the existence of six planes of $\text{PG}(4,q)$ in higgledy-piggledy arrangement, two of which maximally intersect, as well as the existence of two higgledy-piggledy sets in $\text{PG}(5,q)$ consisting of eight planes and seven solids, respectively. Finally, we translate these geometrical results to a coding- and graph-theoretical context.

ABSTRACT
Distance Learning Learning From Home (PJJ BDR) raises so many problems in society. The Covid 19 pandemic has changed the entire order of life, one of which is the learning process. This distance learning seems to be carried out very hastily, considering that so far our society is accustomed to traditional learning patterns. Parents are forced to become teachers for their children, and even teachers must master various types of online-based learning applications. In addition, face-to-face learning systems also change places in virtual classrooms. Facts on the ground, this virtual class is often underestimated and ignored by students for various reasons. So in this study will examine the role of teachers, parents and students in facing distance learning during the Covid 19 pandemic. This research is a qualitative research with a case study method. The results of this study indicate that students, teachers, and parents have an important role that is interrelated with each other in creating success in the learning process, especially distance learning during the current Covid 19 pandemic.

Hepatocellular carcinoma (HCC) is considered one of the most aggressive tumors worldwide. The consumption of lipid-enriched diets, mainly high cholesterol, induces oxidative stress and chronic inflammation, leading to HCC progression. Moreover, fatty acids and cholesterol could display differential responses on immune cells inside the tumor immune microenvironment (TIME). Tumor-associated macrophages (TAMs) represent one of the most critical leukocytes in the tumor microenvironment (TME) displaying pro-tumoral responses and one of the mainly cholesterol donors to cancer cells. Immunotherapy or cholesterol regulators, alone or combined, would represent an effective strategy for HCC treatment. Nonetheless, steatotic etiology from non-alcoholic fatty liver disease (NAFLD)-HCC tumors has been unexpectedly resulting in highly aggressive behavior.

Aim: To evaluate the local impact of the coronavirus disease 2019 (COVID-19) pandemic on breast cancer (BC) care, with particular attention to the economical and psychological consequences of the possible delay of new diagnoses and treatments.
Methods: Three years’ activity (from 2019 to 2021) has been compared. The number of BCs diagnosed from the total amount of mammographic and ultrasound (US) examinations performed in women aged more than 40 years old has been considered. A Pearson’s chi-squared test was performed to verify differences between results. Statistical significance was set at P ≤ 0.01.
Results: A statistically significant difference was found in the number of BC diagnosed between screening and ambulatory care patients in both the 2019–2020 (χ2 = 24.93, P < 0.01) and 2019–2021 (χ2 = 29.93, P < 0.01) comparisons. No statistically significant difference was found in the data recorded between 2020 and 2021 (χ2 = 2.35, P > 0.01). By evaluating the specific age groups for each year, a statistically significant difference (P < 0.01) was found in the number of BC diagnosed in screening patients aged 50–69 years old in both 2019–2020 and 2019–2021 comparisons. The percentages of early BC diagnosed in 2019, 2020, and 2021 were 80.9%, 91.7%, and 89.8%, respectively. The adherence rates to screening in 2019, 2020, and 2021 were 67.5%, 45.2%, and 56.9%, respectively.
Conclusions: Results showed a reduction of new diagnoses in the screening range during the pandemic in comparison with the previous period. The high percentage of early BC would seem to have prevented worsening outcomes. Nevertheless, women who have not undergone screening could present a more advanced stage disease in the following years. Consequently, the evaluation of possible solutions to guarantee an essential level of care with the purpose to avoid worsening patients’ outcomes and the increase in healthcare costs is mandatory.
Are auditory cues special? Evidence from cross-modal distractor-induced blindness
Authors: Kern Lea , Niedeggen Michael
Published: July 2022

A target that shares features with preceding distractor stimuli is less likely to be detected due to a distractor-driven activation of a negative attentional set. This transient impairment in perceiving the target (distractor-induced blindness/deafness) can be found within vision and audition. Recently, the phenomenon was observed in a cross-modal setting involving an auditory target and additional task-relevant visual information (cross-modal distractor-induced deafness). In the current study, consisting of three behavioral experiments, a visual target, indicated by an auditory cue, had to be detected despite the presence of visual distractors. Multiple distractors consistently led to reduced target detection if cue and target appeared in close temporal proximity, confirming cross-modal distractor-induced blindness. However, the effect on target detection was reduced compared to the effect of cross-modal distractor-induced deafness previously observed for reversed modalities. The physical features defining cue and target could not account for the diminished distractor effect in the current cross-modal task. Instead, this finding may be attributed to the auditory cue acting as an especially efficient release signal of the distractor-induced inhibition. Additionally, a multisensory enhancement of visual target detection by the concurrent auditory signal might have contributed to the reduced distractor effect.
The effect of bilingualism on executive functions when languages are similar: a comparison between Hungarian–Serbian and Slovak–Serbian young adult bilinguals

Among the factors argued to contribute to a bilingual advantage in executive function (EF), the combination of languages spoken by the bilingual is often overlooked. In this study, we explored the role of language similarity on memory and EF task by comparing performance of three groups of young adults—Hungarian–Serbian and Slovak–Serbian early balanced bilinguals, and Serbian-speaking monolinguals. Slovak is typologically related to Serbian, which are both Slavic, in contrast to Hungarian, which is Finno–Ugric. On the computerized tasks from the CANTAB battery (CANTAB Cognition, 2016, www.cantab.com), differences between monolinguals and bilinguals emerged on the EF tasks: Stockings of Cambridge (SOC) and Attentional Set Shifting (AST), but not the memory tasks: Delayed Matching to Sample (DMS), Paired Associate Learning (PAL), Spatial Working Memory (SWM). Both Hungarian–Serbian and Slovak–Serbian bilinguals outperformed the monolinguals on the more difficult SOC tasks, solved using more than a minimally required number of moves. This is in line with reports that bilinguals perform better under more complex conditions that require more monitoring and switching. However, bilinguals speaking Hungarian and Serbian spent less time preparing to execute the simpler SOC tasks, which can be solved in a minimum of two or three moves; they also exhibited reduced local switching cost and were faster overall on AST than both the Slovak–Serbian bilinguals and Serbian monolinguals. The advantageous performance of speakers of the typologically unrelated languages in our study suggests that these bilinguals may have more efficient attention switching and inhibition systems than bilinguals who speak typologically similar languages.
Robert Larose’un Teleolojik Çeviri Modeli Temelinde Dipnot İncelemeleri: İstanbul Üçlemesi
Authors: ZEYTİNKAYA Dilber
Published: July 2022

Çeviribilime katkıda bulunmak amacıyla yürütülen bu araştırmanın temelini Robert Larose’un önerdiği bütünleştirici nitelikteki teleolojik (erekbilimsel), amaç odaklı çeviri modeli oluşturmaktadır. Gisèle Durero Köseoğlu’nun Fransızca yazdığı eserlerin çevirileri İstanbul Üçlemesi I: İstanbul’dan Pencereler (2014), İstanbul Üçlemesi II: İstanbul’da Bir El Yazması (2006c), İstanbul Üçlemesi III: Sır Dolu İstanbul (2009b) araştırma nesnesini oluşturmaktadır. Aynı zamanda İstanbul Üçlemesi adlı eserler Gérard Genette’in öne sürdüğü yanmetinler kapsamında çözümlenmiştir. Genette’in metinsel aşkınlık, yanmetinsellik ve metinlerarasılık kavramları irdelenmiş, yanmetinsel öğelerin işlevi ele alınarak metinsel aşkınlık çerçevesinde tartışılmıştır. Larose’un üzerinde yoğunlaştığı metinsel yaklaşım bağlamında dipnot çevirileri değerlendirmeye alınmış, bütünleştirici model kapsamında çeviri için “ön koşullar” ve “sözceleme koşulları” belirlenmeye çalışılmıştır. Larose’un önerdiği Fransızca “traductométrie” ifadesine karşılık olarak “çeviriölçü” ifadesi benimsenmiş, bu tanımlamayla çeviriyi ölçen, değerlendiren bir modele gönderme yapılmıştır. Çeviriölçü yöntemi bağlamında eşdeğerlik kavramının asimetrik doğası, çevirinin benzerlik yapısı, çeviride kazanç-kayıp oranı gibi hususlar irdelenmiştir. Bu araştırma Larose’un teleolojik çeviri modeli temelinde dipnot ve çevirilerini çeviribilimsel sorgulamalarla bütünleştirme gayretinin bir yansıması olarak yürütülmüştür. Larose’un teleolojik çeviri olgusunun çeviri araştırmalarına uyarlanabileceğini kanıtlayan öncül bir araştırma sunma gayreti gösterilmiştir.
