Identitas ganda yang merupakan hal yang wajar dijumpai di dunia nyata, misal transgender salah satunya. Dalam penelitian ini, membedakan buah yang memiliki jenis rasa yang lebih dari satu, seperti buah lemon mempunyai identitas ganda yaitu asam dan asin. Untuk pengkategorisasian Deep Learning, biasanya populasi dataset training memiliki objek yang berbeda satu sama lain. Pada rasa yang terkandung dalam buah, bisa kita eksploitasi untuk melihat perilaku CNN dalam mengenali objek – objek yang memiliki identitas lebih dari satu. Adapun fase training dalam penelitian ini yaitu pada dua kategori rasa yang berbeda dengan sengaja dimasukkan beberapa citra buah yang sama ke dalam dua kategori ini. Akurasi dari pengkategorisasian ini kemudian dibandingkan dengan akurasi dari pengkategorisasian yang murni tidak terdapat objek kembar di tiap – tiap kategorinya. Dari hasil simulasi didapatkan akurasi model ketika ada identitas ganda sebesar 95%, Adapun yang murni didapatkan sebesar 98%.Kata Kunci: Machine Learning, Deep Learning, CNN, Rasa, Buah

Mindfulness-Based Therapies (MBT) are more and more frequently used in the treatment of mental disorders. In the paper the efficacy of meditation programs in the treatment of a variety of mental health problems in diverse adult and adolescent populations and psychological and neurobiological mechanisms underlying these effects were analysed. Intervention studies data supports the efficacy of mindfulness interventions in the treatment of depression, anxiety and addictive disorders. It is proved that mindfulness interventions affect emotion regulation, attention regulation, body awareness and perspective of the self. The effect of mindfulness based interventions in the treatment of mental disorders is supported by scientific rationale of its mechanism of action, and the treatment efficacy data is promising. However, further verification of mindfulness interventions efficacy through a greater number prospective, randomized, controlled clinical research trials is required.

Published: May 2021

Existe una gran variedad de esfuerzos académicos, gubernamentales y de organismos internacionales para explorar las condiciones de personas que viven en pobreza y evaluar políticas que buscan mejorar sus condiciones de vida. En Panamá, sin embargo, los estudios que utilizan datos de encuestas y administrativos sobre las trayectorias de bienestar social de estas personas luego de salir de la pobreza son más limitados, en particular para entender si y cómo estos cambios impactan sus valores, opiniones y comportamientos políticos. El interés de este estudio es proponer una agenda de investigación que busque cerrar esa brecha de conocimiento, de forma tal que 1) integre perspectivas económicas y sociológicas sobre grupos sociales, reconociendo tanto la agencia de cada individuo que forma parte de un grupo como el contexto social y político que limita decisiones individuales; 2) parta desde una hipótesis que justifique la creación de diferentes grupos; 3) sea transparente sobre los objetivos académicos, políticos y sociales que impulsan estas clasificaciones; 4) reconozca las limitaciones y múltiples operacionalizaciones que se pueden utilizar en estos procesos. El estudio concluye con los resultados de una primera aproximación a esta tipología
Adjustments of selective attention to response conflict – controlling for perceptual conflict, target-distractor identity, and congruency level sequence pertaining to the congruency sequence effect
Authors: Tomat Miriam , Wendt Mike , Luna-Rodriguez Aquiles , Jacobsen Thomas 
Published: May 2021

AbstractThe congruency sequence effect (CSE) describes the performance difference of congruent trials (in which target and distractor stimuli are associated with the same response) compared to incongruent trials (in which target and distractor stimuli are associated with different responses) as a function of the preceding congruency level (congruent trials relative to incongruent trials). The CSE is commonly interpreted as a measure of conflict-induced attentional adjustment. Although previous research has made substantial progress aiming at controlling for alternative explanations of the CSE, both task-specific and fundamental confounds have remained. In the current study, we used a temporal flanker task, in which two stimuli (i.e., distractor and target) are presented in rapid succession, and extended previous demonstrations of a CSE in flanker tasks by deconfounding target-distractor congruency from perceptual similarity. Using a four-choice task, we could also control for the reversal of distractor-response priming after incongruent trials (which is only feasible in two-choice tasks). Furthermore, we controlled for all confounds based on the sequence (i.e., repetition versus alternation) of the congruency level – such as feature sequence effects, distractor-response contingency switch costs, or temporal learning – by probing the allocation of attention to the points in time of presentation of the first and the second stimulus of a trial. This was achieved by intermixing trials of a temporal search task. The performance accuracy results in this task were consistent with a stronger attentional bias in favor of the target stimulus’ temporal position after incongruent than after congruent trials.
Distractor filtering is affected by local and global distractor probability, emerges very rapidly but is resistant to extinction
Authors: Valsecchi Matteo , Turatto Massimo 
Published: May 2021

AbstractEffects of statistical learning (SL) of distractor location have been shown to persist when the probabilities of distractor occurrence are equalized across different locations in a so-called extinction phase. Here, we asked whether lingering effects of SL are still observed when a true extinction phase, during which the distractor is completely omitted, is implemented. The results showed that, once established, the effects of SL of distractor location do survive the true extinction phase, indicating that the pattern of suppression in the saliency map is encoded in a form of long-lasting memory. Quite unexpectedly, we also found that the amount of filtering implemented at a given location is not only dictated by the specific rate of distractor occurrence at that location, as previously found, but also by the global distractor probability. We therefore suggest that the visual attention system could be more or less (implicitly) prone to suppression as a function of how often the distractor is encountered overall, and that this suppressive bias affects the degree of suppression at the specific distractor-probability location. Finally, our results showed that the effects of SL of distractor location can appear much more rapidly than has been previously documented, requiring a few trials to become manifest. Hence, SL of distractor location appears to have an asymmetrical rate of learning during acquisition and extinction, while the amount of suppression exerted at a specific distractor location is modulated by distractor contextual probabilistic information.

The project is named as a tribute to the storied Enisala citadel (Dobrogea, Romania). Enisala (“new settlement,” in Turkish and Romanian) sits on top of a windswept hill, at the crossroads of the Danube Delta and the Pontus Euxinus sea (“hospitable sea,” Black Sea), forever shaped by forces of nature. It stands as a metaphor for the ever-evolving galaxy cluster environment and its profound influence on galaxy and black hole evolution. ENISALA can also be understood to stand for “ENvironmental Influence on Star formation and AGN through Line Astrophysics.
project is a collection of multiwavelength observations aimed at understanding how large-scale structure drives galaxy and black hole evolution. Here, we introduce optical spectroscopy of over 800 Hα emission-line galaxies, selected in 14 z ∼ 0.15–0.31 galaxy clusters, spanning a range of masses and dynamical states. We investigate the nature of the emission lines in relation to the host galaxy properties, its location within the cluster, and the properties of the parent cluster. We uncover remarkable differences between mergers and relaxed clusters. The majority of Hα emission-line galaxies in merging cluster fields are located within 3 Mpc of their center. A large fraction of these line emitters in merging clusters are powered by star formation irrespective of cluster-centric radius, while the rest are powered by active galactic nuclei (AGNs). Star-forming galaxies are rare within 3 Mpc of relaxed clusters and AGNs are most abundant at their outskirts (∼1.5–3 Mpc). We discover a population of star-forming galaxies with large equivalent widths and blue UV–optical colors found exclusively in the merging clusters in our sample. The widespread emission-line activity in merging clusters is likely supported by triggered activity in recently accreted, gas-rich galaxies. By contrast, our observations for relaxed clusters match established models in which black hole activity is enhanced at the virial radius and star formation is quenched within the infall region. We conclude that emission-line galaxies experience distinct evolutionary paths in merging and relaxed clusters.
R-process-rich Stellar Streams in the Milky Way*

Published: May 2021

Abstract
We present high-resolution Magellan/MIKE spectra of 22 bright (9 < V < 13.5) metal-poor stars (−3.18 < [Fe/H] < −1.37) in three different stellar streams, the Helmi debris stream, the Helmi trail stream, and the ω Centauri progenitor stream. We augment our Helmi debris sample with results for 10 stars by Roederer et al. for a total of 32 stars. Detailed chemical abundances of light elements as well as heavy neutron-capture elements have been determined for our 22 stars. All three streams contain carbon-enhanced stars. For 13 stars, neutron-capture element lines were detectable, and they all show signatures in agreement with the scaled solar r-process pattern, albeit with a large spread of −0.5 < [Eu/Fe] < +1.3. Eight of these stars show an additional small s-process contribution superposed onto their r-process pattern. This could be discerned because of the relatively high signal-to-noise ratio of the spectra given that the stars are close by in the halo. Our results suggest that the progenitors of these streams experienced one or more r-process events early on, such as a neutron star merger or another prolific r-process source. This widely enriched these host systems before their accretion by the Milky Way. The small s-process contribution suggests the presence of asymptotic giant branch stars and associated local (inhomogeneous) enrichment as part of the ongoing chemical evolution by low-mass stars. Stars in stellar streams may thus be a promising avenue for studying the detailed history of large dwarf galaxies and their role in halo assembly with easily accessible targets for high-quality spectra of many stars.
Multimessenger Signals from Black Hole–Neutron Star Mergers without Significant Tidal Disruption

Published: May 2021

Abstract
We study the multimessenger signals from the merger of a black hole with a magnetized neutron star using resistive magnetohydrodynamics simulations coupled to full general relativity. We focus on a case with a 5:1 mass ratio, where only a small amount of the neutron star matter remains post-merger, but we nevertheless find that significant electromagnetic radiation can be powered by the interaction of the neutron star’s magnetosphere with the black hole. In the lead-up to merger, strong twisting of magnetic field lines from the inspiral leads to plasmoid emission and results in a luminosity in excess of that expected from unipolar induction. We find that the strongest emission occurs shortly after merger during a transitory period in which magnetic loops form and escape the central region. The remaining magnetic field collimates around the spin axis of the remnant black hole before dissipating, an indication that, in more favorable scenarios (higher black hole spin/lower mass ratio) with larger accretion disks, a jet would form.

Abstract
We present the sympathetic eruption of a standard and a blowout coronal jet originating from two adjacent coronal bright points (CBP1 and CBP2) in a polar coronal hole, using soft X-ray and extreme-ultraviolet observations respectively taken by the Hinode and the Solar Dynamics Observatory. In the event, a collimated jet with obvious westward lateral motion first launched from CBP1, during which a small bright point appeared around CBP1's east end, and magnetic flux cancellation was observed within the eruption source region. Based on these characteristics, we interpret the observed jet as a standard jet associated with photospheric magnetic flux cancellation. About 15 minutes later, the westward-moving jet spire interacted with CBP2 and resulted in magnetic reconnection between them, which caused the formation of the second jet above CBP2 and the appearance of a bright loop system in between the two CBPs. In addition, we observed the writhing, kinking, and violent eruption of a small kink structure close to CBP2's west end but inside the jet base, which made the second jet brighter and broader than the first one. These features suggest that the second jet should be a blowout jet triggered by the magnetic reconnection between CBP2 and the spire of the first jet. We conclude that the two successive jets were physically connected to each other rather than a temporal coincidence, and this observation also suggests that coronal jets can be triggered by external eruptions or disturbances, as well as internal magnetic activities or magnetohydrodynamic instabilities.

Authors: Abumettleq Ibrahim S S , Bayraktar Nurhan 
Published: May 2021

Introduction: The increasing number of persons > 65 years of age form a special population at risk for nosocomial and other health care-associated infections. Nosocomial infections are major problems in terms of morbidity and mortality as well as prolonged hospitalization and increased costs. The aim of the present study was determination of nurses’ awareness of hospital-acquired infection risks of the geriatric patients.
Methodology: This descriptive and cross-sectional study was conducted at a university hospital in North Cyprus. A total of 164 voluntary nurses composed the sample of the study. A questionnaire that was developed by the researchers based on the literature was used as data collection tool. After the ethical approval, data were collected using a questionnaire in September and October 2017 with self-completion method. The methods used to analyze the data include an analysis of descriptive statistic variables such as frequency and percentages for the categorical variables and the Pearson’s Chi-square test for comparisons.
Results: Results of the study showed inadequate awareness among nurses on hospital-acquired infection risks of the geriatric patients. It was also determined that there were the statistically significant differences in term of education levels and experiences of nurses with different items on hospital-acquired infection risks of the geriatric patients.
Conclusions: Based on the results of the study, implementations of comprehensive, systematic, and continuous educational programs to enhance awareness of the nurses on health care-associated infections was recommended.

Introduction: Health care workers (HCWs), especially from sub-Saharan Africa, are at risk of occupational exposure to HIV. Post exposure prophylaxis (PEP) can reduce this risk. There is no published information from Zimbabwe, a high HIV burden country, about how PEP works. We therefore assessed how the PEP programme performed at the Parirenyatwa Hospital, Harare, Zimbabwe, from 2017-2018.
Methodology: This was a cohort study using secondary data from the staff clinic paper-based register. The chi square test and relative risks were used to assess associations.
Results: There were 154 HCWs who experienced occupational injuries. The commonest group was medical doctors (36%) and needle sticks were the most frequent type of occupational injury (74%). The exposure source was identified in 114 (74%) occupational injuries: 91% of source patients were HIV-tested and 77% were HIV-positive. All but two HCWs were HIV-tested, 148 were eligible for PEP and 142 (96%) started triple therapy, all within 48 hours of exposure. Of those starting PEP, 15 (11%) completed 28 days, 13 (9%) completed < 28 days and in the remainder PEP duration was not recorded. There were no HCW characteristics associated with not completing PEP. Of those starting PEP, 9 (6%) were HIV-tested at 6-weeks, 3 (2%) were HIV-tested at 3-months and 1 (< 1%) was HIV-tested at 6-months: all HIV-tests were negative.
Conclusions: While uptake of PEP was timely and high, the majority of HCWs failed to complete the 28-day treatment course and even fewer attended for follow-up HIV-tests. Various changes are recommended to promote awareness of PEP and improve adherence to guidelines.

Introduction: Typhoid incidence in children is higher in urban areas than in rural areas of Bangladesh. This study examined whether healthy urban children harboured higher levels of Salmonella genes than healthy rural children.
Methodology: Stool samples from 140 children were studied: 70 from rural areas and 70 from urban metropolitan areas.
Results: The stool samples of urban children contained more Salmonella genes (median 4, IQR 3-4) than those of rural children (median 3, IQR 3-4). This suggests that urban Bangladeshi children have more Salmonella genes in their guts than rural children. Especially, in those under 12 months of age, the Salmonella gene prevalence in urban children was unique. They had more Salmonella genes (median 4, IQR 4-5) than rural children in the same age group (median 3, IQR 2.5-4). We also found more Salmonella genes in urban children who drank tap water (median 4, IQR 3-5) than in rural children whose water source was tube well water (median 3, IQR 2-4) and boiled pond water (median 3, IQR 3-3.5). However, there was no significant difference of Salmonella genes between urban children who drank tap-water and children whose water source was a tube well (median 4, IQR 3-4).
Conclusions: These data suggest that the urban environment, including the drinking water supply system, increases the likelihood of healthy children in urban areas harbouring more potentially pathogenic Salmonella organisms in their gut than found in rural healthy children.
