Abstract
We report on the fabrication of Josephson junction devices with weak links utilizing the Weyl and higher-order topological semimetal WTe2. We show that the WTe2/Pd contact annealed at a low temperature of 80 °C did not exhibit superconducting properties because neither WTe2 nor Pd are superconductors in the ground state. Upon 180 °C annealing, spontaneous formation of superconducting PdTe due to Pd diffusion enabled us to obtain the interface between WTe2 and superconductor suitable for the Josephson junction. This result is a facile technique to make a Josephson junction and induce Cooper pairs into topological telluride semimetals.

Published: June 2022

Abstract
A type of ferroelectric polymer thin-film memristors is demonstrated to show their potential in the emulation of synaptic plasticity. The memristive characteristics of the device arise from the design of asymmetric top electrodes capacitively coupled with a floating bottom electrode, which enables the local modulation of ferroelectric polarization in the ferroelectric terpolymer film. Basic synaptic functions, such as continuous increase/decrease in synaptic weight and paired-pulse facilitation, are successfully emulated using the ferroelectric polymer memristors. This work provides a promising approach to implementing ferroelectric mechanisms in electronic synapses.

Published: June 2022

<p>Objective: The heart sound signals captured via a digital stethoscope are often distorted by environmental and physiological noise, altering their salient and critical properties. The problem is exacerbated in crowded low-resource hospital settings with high noise levels which degrades the diagnostic performance. In this study, we present a novel deep encoder-decoder based denoising architecture (LU-Net) to suppress ambient and internal lung sound noises. Methods: Training is done using a large benchmark PCG dataset mixed with physiological noise, i.e., breathing sounds. Two different noisy datasets were prepared for experimental evaluation by mixing unseen lung sounds and hospital ambient noises with the clean heart sound recordings. We also use the inherently noisy portion of the PASCAL heart sound dataset for evaluation. Results: The proposed framework showed effective suppression of background noises in both un?seen real-world data and synthetically generated noisy heart sound recordings, improving the signal-to-noise ratio (SNR) level by 5.575 dB on an average using only 1.32 M parameters. The proposed model outperforms the current state-of-the-art U-Net model with an average SNR improvement of 5.613 dB and 5.537 dB in the presence of lung sound and unseen hospital noise, respectively. LU-Net also outperformed the state-of-the-art Fully Convolutional Network (FCN) by 1.750 dB and 1.748 dB for lung sound and unseen hospital noise conditions, respectively. In addition, the proposed denoising method model improves classification accuracy by 38.93% in the noisy portion of the PASCAL heart sound dataset. Conclusion: The results presented in the paper indicate that our proposed architecture demonstrated a robust denoising performance on different datasets with diverse levels and characteristics of noise. Significance: The proposed deep learning-based PCG denoising approach is a pioneering study that can significantly improve the accuracy of computer-aided auscultation systems for detecting cardiac diseases in noisy, low-resource hospitals and underserved communities. </p>

Published: June 2022

Desa Bumiwangi merupakan desa pemekaran yang sebelumnya tergabung ke Desa Ciheulang berada di Kecamatan Ciparay Kabupaten Bandung. Sebagai desa yang relatif masih muda, belum banyak capaian yang diraih oleh desa ini. Karenanya kepala desa mempunyai misi salah satunya untuk menggali potensi dan sumber pendapatan baru yang dapat dikembangakan guna meningkatkan pendapatan asli daerah. Salah satu upayanya adalah dengan menjadikan desa yang sebelumnya jarang dikunjungi orang menjadi desa wisata. Pemerintah Desa sudah membuat site plan dan mulai membangun berbagai infrastuktur untuk mewujudkan kawasan Bukit Cula Desa Bumiwangi sebagai kawasan wisata desa. Beberapa kali pula Desa Bumiwangi mengadakan festival seni budaya sebagai daya pikat masyarakat luar untuk berkunjung ke wilayah tersebut, namun gaungnya masih belum terasa dan masyarakat luar masih belum terpapar informasi dari berbagai kegiatan yang dilaksanakan. Dari permasalahan tersebut, dibutuhkan publikasi di media massa serta media promosi lainnya. Cara yang dirasa cukup efektif dan tidak memakan biaya yang tinggi adalah dengan pemanfaatan media teknologi komunikasi informasi, seperti mengaktifkan website desa serta menginformasikan desa wisata ini melalui media sosial oleh masyarakat. Untuk itu diperlukan adanya pelatihan dan pendampingan secara komprehensif bagaimana membina hubungan yang baik dengan media massa (media relations), serta bagaimana cara mendesain pesan yang baik dan membuat liputan kegiatan yang nantinya akan disebarkan melalui media digital yang telah ada. Kegiatan ini menghasilkan 4 liputan di koran online, website resmi desa, serta konten warga tentang bukit cula di media social seperti instagram, youtube, facebook, dan twitter.

MARS: A New Maximum-entropy-regularized Strong Lensing Mass Reconstruction Method
Authors: Cha Sangjun , Jee M. James 
Published: June 2022

Abstract
Free-form strong-lensing (SL) mass reconstructions typically suffer from overfitting, which manifests itself as false-positive small-scale fluctuations. We present a new free-form MAximum-entropy ReconStruction (MARS) method without the assumption that light traces mass (LTM). The MARS algorithm enables us to achieve excellent convergence in source positions (∼0.″001), minimize spurious small-scale fluctuations, and provide a quasi-unique solution independently of initial conditions. Our method is tested with the publicly available synthetic SL data FF-SIMS. The comparison with the truth shows that the mass reconstruction quality is on par with those of the best-performing LTM methods published in the literature, which have been demonstrated to outperform existing free-form methods. In terms of the radial mass profile reconstruction, we achieve <1% agreement with the truth for the regions constrained by multiple images. Finally, we apply MARS to A1689 and find that the cluster mass in the SL regime is dominated by the primary halo centered on the brightest cluster galaxy and the weaker secondary halo is also coincident with the bright cluster member ∼160 kpc northeast. Within the SL field, the A1689 radial profile is well described by a Navarro–Frenk–White profile with c

Abstract
During reionization, a fraction of galactic Lyα emission is scattered in the intergalactic medium (IGM) and appears as diffuse light extending megaparsecs from the source. We investigate how to probe the properties of the early galaxies and their surrounding IGM using this scattered light. We create a Monte Carlo algorithm to track individual photons and reproduce several test cases from previous literature. Then, we run our code on the simulated IGM of the CoDaII simulation. We find that the scattered light can leave an observable imprint on the emergent spectrum if collected over several square arcminutes. Scattering can redden the emission by increasing the path lengths of photons, but it can also make the photons bluer by upscattering them according to the peculiar motion of the scatterer. The photons emitted on the far blue side of the resonance appear more extended in both frequency and space compared to those emitted near the resonance. This provides a discriminating feature for the blueward emission, which cannot be constrained from the unscattered light coming directly from the source. The ionization state of the IGM also affects the scattered light spectrum. When the source is in a small H ii region, the emission goes through more scatterings in the surrounding H i region regardless of the initial frequency and ends up more redshifted and spatially extended. This can result in a weakening of the scattered light toward high z during reionization. Our results provide a framework for interpreting the scattered light to be measured by high-z integral-field-unit surveys.
Not That Simple: The Metallicity Dependence of the Wide Binary Fraction Changes with Separation and Stellar Mass
Authors: Niu Zexi , Yuan Haibo , Wang Yilun , Liu Jifeng 
Published: June 2022

Abstract
The metallicity dependence of the wide binary fraction (WBF) is critical for studying the formation of wide binaries. While controversial results have been found in recent years, here we combine the wide binary catalog recognized from Gaia EDR3 and stellar parameters from LAMOST to investigate this topic. Taking the bias of the stellar temperature at given separations into account, we find that the relationship between the WBF and metallicity depends on the temperature for the thin disk at s > 200 au. It changes from negative to positive as the temperature increases from 4000 to 7500 K. This temperature/mass dependence is not seen for the thick disk. Besides, the general tendency between the WBF and metallicity varies with the separation, consistent with previous results. It shows anticorrelation at small separations, s < 200 au for the thin disk and s < 600 au for the thick disk. Then it becomes an “arcuate” shape at larger separations (hundreds to thousands of astronomical units), peaking at [Fe/H] ≈0.1 for the thin disk and [Fe/H] ≈−0.5 for the thick disk. Finally it becomes roughly flat for the thin disk at 1000 < s < 10,000 au. Our work provides new observational evidence for theoretical studies on binary formation and evolution.

Published: June 2022

Introduction: Invasive candidiasis is a severe form of infection. The incidence of invasive fungal infections has increased, due to the increasing number of patients with impaired immunity who are being treated through prolonged stay in hospital facilities. Neurological patient treatment methods such as antimicrobials, corticosteroid, central venous catheter (CVC), total parenteral nutrition, and mechanical ventilation use are associated with common risk factors for invasive candidiasis. Our study demonstrated invasive candidiasis prevalence among neurological patients.
Methodology: A cross-sectional study was done with consecutive sampling of neurological patients who were hospitalized from January 2017 to February 2020 at the Mahar Mardjono National Brain Center Hospital East Jakarta Indonesia. Patients with sepsis, septic shock, or fever (> 38.5 °C), and who had not received antifungals before culture were enrolled in the study. Clinical specimens were obtained from blood, liquor cerebrospinal or other sterile sites, CVC, respiratory tract specimens, and urine or other non-sterile sites. Socio-demographic data, potential risk factors based on previous studies, clinical, and other tests data were obtained from medical records. Classification of invasive candidiasis was according to the Paphitou classification criteria.
Results: One hundred and two subjects met the study criteria. The prevalence of invasive candidiasis in neurological patients was 13.7%. All of the isolates were C. parapsilosis.
Conclusions: The prevalence of invasive candidiasis was high in the samples studied. The infection was associated with septic shock, tracheostomy, and duration of use of central venous catheter, ventilator, and steroids.

Published: June 2022

Introduction: Acinetobacter baumannii, a pathogen of concern in hospitals worldwide, has diverse antimicrobial resistance mechanisms leading to limiting the antibiotic options and carbapenemase enzyme production is one of the common mechanisms in carbapenem resistance. The epidemiology and resistance pattern of clinical isolates are critical in developing a prevention and treatment strategy. The aim of this was to determine the prevalence and resistance pattern of carbapenem non-susceptible strains (CNS) A. baumannii at Arifin Achmad General Hospital, Pekanbaru, Indonesia.
Methodology: Data were retrieved from the culture and susceptibility test results from various clinical specimens from January 2015 to December 2019. A susceptibility test was conducted using Vitek 2 Compact following the manufacturer’s protocol. To explore the genetic profile of CNS A. baumannii, we amplified the blaOXA-23 and blaOXA-51 genes, carbapenemase producing genes, using a duplex polymerase chain reaction (PCR) among 24 isolates Chi-squared was used to assess the factors associated with the presence of CNS A. baumannii.
Results: Between 2015-2019, 1.263 A. baumannii isolates were tested and the prevalence of CNS A. baumannii was 50%. The trend decreased from 53% in 2016 to 45% in 2019. The proportion of CNS A. baumannii was higher among samples from patients treated in the Intensive Care Unit (ICU) compared to non-ICU (p < 0.001). The CNS A. baumannii was also more frequently detected from sputum than from non-sputum samples (p = 0.009). CNS A. baumannii were highly resistant to almost all antibiotics and the highest susceptibility was to amikacin, tigecycline, and trimethoprim/sulfamethoxazole with 64%, 53%, and 43%, respectively. The blaOXA-23 gene was detected in 92% of tested CNS A. baumannii isolates.
Conclusions: The prevalence of CNS A. baumannii is high at Arifin Achmad Hospital Riau, Indonesia. This is also supported by the high prevalence of the blaOXA-23 gene among tested isolates. Based on the antibiotic susceptibility pattern there are limited antibiotic choices for CNS A. baummannii urging the strengthening of antimicrobial stewardship programs in the country.
