G-Learn A Graph Machine Learning Content Recommendation System for Virtual Learning Environments
Authors: Damasceno Hugo , Rocha Leonardo , Serra Antonio 
Published: October 2023

<p>Recommender Systems are information systems that provide personalized suggestions or recommendations to users based on their preferences, interaction history, and behavior patterns. An important use of recommender systems is in Virtual Learning Environments (VLEs), i.e. remote learning platforms where students can access educational materials, activities, assessments, etc., where they offer significant benefits to both students and instructors. Such benefits include personalized learning, increased engagement and effectiveness of both teaching and learning tasks. </p>
<p>Challenges for the use of recommendation systems in VLEs include the cold start problem, data sparsity, and limited coverage.</p>
<p>To deal with these challenges, we propose G-Learn, a recommendation system for contents in VLEs that can operate in both supervised and unsupervised modes. The recommendations are based on graph machine learning techniques combined with keyword mining and similarity, allowing the system to recommend educational materials that are adapted to the performance of each student detected when the student solves questions on the platform. </p>
<p>We show the effectiveness of G-learn in a realistic scenario, using data from the VLE Homero, a computer science platform supported by the federal government of Brazil. We compare different settings for the keyword mining and machine learning techniques. Real data from students is used to validate the recommendation graphs, where G-learn obtained an average f1-score of 0.64 in the unsupervised mode and 0.95 in the supervised one.</p>

Published: October 2023

Objective: Irritable bowel syndrome (IBS) is a chronic, functional disorder of the gastrointestinal tract. Recent investigations have highlighted the potential involvement of inflammation, although the etiology of IBS remains unknown. This study aims to assess the connection between IBS and Monocyte/High-Density Lipoprotein (HDL) ratio (MHR), a new inflammatory marker.
Material and Method: The study was conducted in the outpatient gastroenterology unit of a tertiary center between March-2021 and March-2022. Patients with IBS, according to the Rome IV criteria were examined retrospectively. Age- and sex-matched healthy controls were used to compute MHR and compare the results.
Results: A total of 255 participants, 155 diagnosed with IBS and 100 in the control group, were included. The median (min-max) monocyte counts (cells/mm³) in the IBS and control groups were 380.0 (310.0-460.0) and 332.0 (232.0-449.3), respectively (p = 0.008). The median(min-max) HDL levels(mg/dl) in IBS and control groups were 45.0(36.0-55.0) and 49.0(43.0-57.0), respectively(p=0.001). The median MHR was higher in the IBS group (9.5) compared to healthy controls (6.73, p<0.001). Logistic regression analysis revealed MHR as an independent predictor of the presence of IBS (OR: 1.406, 95% CI: [insert confidence interval]). The cut-off value for MHR to detect IBS with 62.6% sensitivity and 63.0% specificity was 7.57, and ROC analysis revealed an AUROC value of 0.646 (95% CI: 0.577-0.715, p<0.001).
Discussion: The study's primary findings were that IBS patients had significantly lower levels of HDL cholesterol and significantly higher levels of monocyte counts when compared to the control group. Consequently, monocyte/HDL ratios (MHR) were statistically substantially greater in IBS patients than in the control group. Furthermore, when the cut-off value was set at 7.6, MHR was found to be an independent predictor for IBS, with 62.6% sensitivity and 63.0% specificity.
Conclusion: MHR can be a simple, inexpensive, and effective tool to demonstrate the inflammatory state in patients with IBS.

В работе приводятся результаты натурных экспериментальных исследований параметров микроклимата внутреннего воздуха в рабочей зоне. Целью исследований являлось выявление путем сравнительного анализа отклонений экспериментальных значений параметров микроклимата от нормативных, для реализации мер по повышению производительности труда человека на рабочем месте. В работе описываются проведенные авторами натурные экспериментальные исследования по определению ТНС-индекса. Измерения выполнялись «мокрым» и «сухим» термометром, а также сферой Вернона. В результате эксперимента установлено, что экспериментальные значения параметров микроклимата не соответствуют нормативным. Обоснована целесообразность использования полученных результатов при интегральной оценке тепловой нагрузки среды на рабочих местах.
This paper presents the results of experimental studies of the parameters of the indoor air microclimate in the working area. The aim of the study is to identify deviations of normative and experimental values of microclimate parameters by comparative analysis, which might increase human productivity in the workplace. The paper describes the experimental studies and the results of the analysis of the TNS index. We carried out the measurements with a wet thermometer, dry thermometer and Vernon sphere. The results of the experiment showed that the experimental values do not correspond to the normative ones. It is suggested that the obtained values should be used when compiling the thermal balance of the room.

Weighted sums method applied for decision making in improvement towards complete street: a case study in Popayan, Colombia
Authors: Albán-Pérez Carlos Andrés , Serrano-Guzmán María Fernanda , Pérez-Ruiz Diego Dario 
Published: October 2023

The design of a street must adhere to functionality requirements that ensure the safety and comfort of users. From this perspective, if a street encompasses attributes of safety, inclusivity, sustainability, and resilience, it can be referred to as a complete street. This study presents the application of the weighted sum method for evaluating the conditions of a complete street in the modernization of the road network in Popayán, considering the impact that different alternatives offer to enhance road quality. Prior to implementing this method, a group of experts defined the weight of each attribute of a complete street, and using a compliance checklist, a visual assessment was conducted across four sections in the city.
The study provides an example of rating a segment within a study section and the economic impact in relation to the benefits of the implemented improvements to achieve complete street functionality. This procedure enables a project manager or public expenditure manager to assess how to enhance the success or integrity of the street before carrying out a public project. The goal of the weighted sum method applied in this scenario is to provide a tool for evaluating the fulfillment of complete street conditions before commencing construction.
The effects of a story-telling approach on sixth-grade pupils' values, attitudes and motivation with regard to studies of the human nervous system
Authors: Sali Hüseyin , Aydin Mirac 
Published: October 2023

The current study investigates the effects of instruction with the storytelling approach on sixth-graders’ values, attitudes and motivation in relation to the study of the human nervous system. The instruction consisted of a series of lessons on the human nervous system in which nine stories were included. The study employed a one-group pre-test and post-test design. Twenty-four pupils, all of whom were girls, participated in the study. The Dilemma Cases Form (Inventory), an attitude scale towards science, and a motivation scale for science were administered before and after the intervention. Pre and post-tests were compared using the non-parametric Wilcoxson’s Rank Sum Tests. The results indicated that sixth-graders who were exposed to story-telling as part of the instruction improved their scores on the values and attitudes toward science scales but not those for motivation. Based on the results, it is argued that the story-telling approach in the unit on the human nervous system could be a good source of enrichment for sixth graders in science education.
Prevalence of Adrenal Incidentaloma by Chest Computed Tomography in Patients with a Preliminary Diagnosis of COVID-19 Pneumonia
Authors: KULA Osman , ÇELİK Ahmet Onur , GÜNAY Burak 
Published: October 2023

Aim: Adrenal incidentalomas are typically discovered as an incidental finding during routine computed tomography (CT) or magnetic resonance imaging (MRI) scans conducted for unrelated purposes. Our objective was to examine the frequency of adrenal incidentaloma, in individuals who underwent thoracic CT scan as a result of Covid-19 infection.
Material and Methods: In the retrospective descriptive study, 808 patients who applied to the emergency radiology department with the suspicion of covid 19 and underwent thoracic CT between March 2020 and July 2020 were included. The presence of incidentaloma in the CT images of the patients was evaluated.
Results: Adrenal incidentaloma was detected in 78 (9.7%) of the 808 patients, and of those 78 adrenal incidentalomas, 70 (8.7%) were unilateral and 8 (1%) were bilateral. The mean diameter of the adrenal incidentaloma was 20 mm, and it was 18.5 mm in females and 21.5 mm in males. A total of 808 patients, 351 (43.4%) females and 457 (56.6%) males, were included in the study.
Conclusion: Adrenal incidentaloma have become more common radiological findings with the recent COVID-19 pandemic due to the increased frequency of CT scans, and it is important to appropriately manage these patients.
Systematically Measuring Ultradiffuse Galaxies (SMUDGes). IV. Ultradiffuse Satellites of Milky Way Analogs
Authors: Goto Hina , Zaritsky Dennis , Karunakaran Ananthan , Donnerstein Richard , Sand David J. 
Published: October 2023

Abstract
To better understand the formation of large, low-surface-brightness galaxies, we measure the correlation function between ultradiffuse galaxy (UDG) candidates and Milky Way analogs (MWAs). We find that: (1) the projected radial distribution of UDG satellites (projected surface density ∝r
−0.84±0.06) is consistent with that of normal satellite galaxies; (2) the number of UDG satellites per MWA (S
UDG) is ∼0.5 ± 0.1 over projected radii from 20 to 250 kpc and −17 < M

r
< −13.5; (3) S
UDG is consistent with a linear extrapolation of the relationship between the number of UDGs per halo versus halo mass obtained over galaxy group and cluster scales; (4) red UDG satellites dominate the population of UDG satellites (∼80%); (5) over the range of satellite magnitudes studied, UDG satellites comprise ∼10% of the satellite galaxy population of MWAs; and (6) a significant fraction of these (∼13%) have estimated total masses >1010.9
M
⊙ or, equivalently, at least half the halo mass of the LMC, and populate a large fraction (∼18%) of the expected subhalos down to these masses. All of these results suggest a close association between the overall low-mass galaxy population and UDGs, which we interpret as favoring models where UDG formation principally occurs within the general context of low-mass galaxy formation over models invoking more exotic physical processes specifically invoked to form UDGs.

Abstract
We present timing solutions for 21 pulsars discovered in 350 MHz surveys using the Green Bank Telescope (GBT). All were discovered in the Green Bank North Celestial Cap pulsar survey, with the exception of PSR J0957−0619, which was found in the GBT 350 MHz Drift-scan pulsar survey. The majority of our timing observations were made with the GBT at 820 MHz. With a spin period of 37 ms and a 528 days orbit, PSR J0032+6946 joins a small group of five other mildly recycled wide binary pulsars, for which the duration of recycling through accretion is limited by the length of the companion’s giant phase. PSRs J0141+6303 and J1327+3423 are new disrupted recycled pulsars. We incorporate Arecibo observations from the NANOGrav pulsar timing array into our analysis of the latter. We also observed PSR J1327+3423 with the Long Wavelength Array, and our data suggest a frequency-dependent dispersion measure. PSR J0957−0619 was discovered as a rotating radio transient, but is a nulling pulsar at 820 MHz. PSR J1239+3239 is a new millisecond pulsar (MSP) in a 4 days orbit with a low-mass companion. Four of our pulsars already have published timing solutions, which we update in this work: the recycled wide binary PSR J0214+5222, the noneclipsing black widow PSR J0636+5128, the disrupted recycled pulsar J1434+7257, and the eclipsing binary MSP J1816+4510, which is in an 8.7 hr orbit with a redback-mass companion.
Direct Observations of Reconnection Fronts in Earth's Turbulent Magnetosheath
Authors: Liu C. M. , Xing X. N. , Cao J. B. 
Published: October 2023

Abstract
Reconnection fronts (RFs), ion-scale magnetic transients characterized by dramatic enhancement of reconnected magnetic fields, have been documented as crucial energy transfer regions during magnetic reconnection. RFs have hitherto been observed only in the planetary (e.g., Earth, Saturn, Mars, and Venus) magnetotails. Whether RFs can exist in other magnetospheric regions remains unclear. Here, using high-cadence data from NASA’s Magnetospheric Multiscale mission, we present the first observation of successive RFs in Earth's turbulent magnetosheath. The RFs were detected inside an ion diffusion region and several di (ion inertial length) away from reconnection X-line. In addition, we find that the strongest energy conversion occurs at the RF rather than at the X-line. The present observation indicates that RFs may be universal in the planetary magnetosphere and play a crucial role in the reconnection dynamics.

Abstract
We present the results of processing the effects of the powerful gamma-ray burst GRB221009A captured by the charged particle detectors (electrostatic analyzers and solid-state detectors) on board spacecraft at different points in the heliosphere on 2022 October 9. To follow the GRB221009A propagation through the heliosphere, we used the electron and proton flux measurements from solar missions Solar Orbiter and STEREO-A; Earth’s magnetosphere and solar wind missions THEMIS and Wind; meteorological satellites POES15, POES19, and MetOp3; and MAVEN—a NASA mission orbiting Mars. GRB221009A had a structure of four bursts: the less intense Pulse 1—the triggering impulse—was detected by gamma-ray observatories at T
0 = 13:16:59 UT (near the Earth); the most intense Pulses 2 and 3 were detected on board all the spacecraft from the list; and Pulse 4 was detected in more than 500 s after Pulse 1. Due to their different scientific objectives, the spacecraft, whose data were used in this study, were separated by more than 1 au (Solar Orbiter and MAVEN). This enabled the tracking of GRB221009A as it was propagating across the heliosphere. STEREO-A was the first to register Pulse 2 and 3 of the GRB, almost 100 s before their detection by spacecraft in the vicinity of Earth. MAVEN detected GRB221009A Pulses 2, 3, and 4 at the orbit of Mars about 237 s after their detection near Earth. By processing the observed time delays, we show that the source location of the GRB221009A was at R.A. 288.°5, decl. 18.°5 ± 2° (J2000).
Fortuitous Observations of Potential Stellar Relay Probe Positions with GBT
Authors: Palumbo Michael L. , Wright Jason T. , Huston Macy J. 
Published: October 2023

Abstract
Recent theoretical and observational works have investigated the possibility that extraterrestrial intelligence could use the Sun as a gravitational lens in order to aid communication across interstellar distances. Unlike other targeted SETI searches where the drift rate of any artificial extraterrestrial signals may be unknown up to some large upper limit, the drift rates of any solar system relay probes would be known and set only by the motion of the Earth. One recent work used purpose-designed Green Bank Telescope (GBT) observations to search for signals from a hypothetical communications probe several hundred astronomical unit from the Sun at the antipode of the α Centauri AB system. To further aid in the advancement of relay-probe searches, we present a table of 1764 archival GBT observations which fortuitously fall near the positions of hypothetical probes communicating with stars within 100 pc and compute the drift rates for these probes.
Interfaces hospitalières et solitudes

Published: October 2023

La première vague de la pandémie de Covid 19 a modifié les modalités de prise en charge des malades. Les examens cardiologiques, souvent au contact prolongé des patients, ont été pratiqués avec des tenues adaptées visant à protéger de la contamination non plus les malades mais les soignants. Les restrictions de visite des proches auprès des hospitalisés ont quant à elles donné une nouvelle dimension à la relation soignant-soigné lors du séjour hospitalier. Les déséquilibres liés à ces changements, le plus souvent surmontés, soulignent l’importance des relations soignants-soignés, et la nécessité de les préserver dans une évolution de la médecine de plus en plus tournée vers la technicité, pour ne pas lui faire perdre sa dimension humaniste.

Published: October 2023

La mort d’un parent, d’un frère n’est pas forcément intégrée durant l’enfance. L’acquisition du sens de la mort est progressive, elle est liée aux stades de développement cognitif et psychoaffectif de l’enfant. Celui-ci est beaucoup dans la pensée magique : tout ce qu’il pense peut arriver, ce qui peut engendrer un sentiment de culpabilité.
