Abstract
Despite increasing interest in tin disulfide (SnS2) as a two-dimensional (2D) material due to its promising electrical and optical properties, the surface treatment of silicon dioxide (SiO2) substrates prior to the atomic layer deposition (ALD) deposition of SnS2 has not been thoroughly studied. In this paper, we prepared two types of SiO2 substrates with and without using an O2 plasma surface treatment and compared the ALD growth behavior of SnS2 on the SiO2 substrates. The hydrophilic properties of the two SiO2 substrates were investigated by x-ray photoelectron spectroscopy and contact angle measurements, which showed that using an O2 plasma surface treatment tuned the surface to be more hydrophilic. ALD-grown SnS2 thin films on the two different SiO2 substrates were characterized by x-ray diffraction, Raman spectroscopy, atomic force microscopy, and x-ray photoelectron spectroscopy. To estimate the exact thickness of the ALD-grown SnS2 thin films, transmission electron microscopy was used. Our data revealed that using O2 plasma surface treatment increased the growth rate of the initial ALD stage. Thus, the ALD-grown SnS2 thin film on the SiO2 substrate treated with O2 plasma was thicker than the film grown on the non-treated SiO2 substrate.
Skyrmion dynamics and topological sorting on periodic obstacle arrays
Authors: Vizarim N P , Reichhardt C , Reichhardt C J O , Venegas P A 
Published: March 2020

Abstract
We examine skyrmions under a dc drive interacting with a square array of obstacles for varied obstacle size and damping. When the drive is applied in a fixed direction, we find that the skyrmions are initially guided in the drive direction but also move transverse to the drive due to the Magnus force. The skyrmion Hall angle, which indicates the difference between the skyrmion direction of motion and the drive direction, increases with drive in a series of quantized steps as a result of the locking of the skyrmion motion to specific symmetry directions of the obstacle array. On these steps, the skyrmions collide with an integer number of obstacles to create a periodic motion. The transitions between the different locking steps are associated with jumps or dips in the velocity–force curves. In some regimes, the skyrmion Hall angle is actually higher than the intrinsic skyrmion Hall angle that would appear in the absence of obstacles. In the limit of zero damping, the skyrmion Hall angle is 90°, and we find that it decreases as the damping increases. For multiple interacting skyrmion species in the collective regime, we find jammed behavior at low drives where the different skyrmion species are strongly coupled and move in the same direction. As the drive increases, the species decouple and each can lock to a different symmetry direction of the obstacle lattice, making it possible to perform topological sorting in analogy to the particle sorting methods used to fractionate different species of colloidal particles moving over two-dimensional obstacle arrays.

Published: March 2020

Abstract
To date, individual addressing of ion qubits has relied primarily on local Rabi or transition frequency differences between ions created via electromagnetic field spatial gradients or via ion transport operations. Alternatively, it is possible to synthesize arbitrary local one-qubit gates by leveraging local phase differences in a global driving field. Here we report individual addressing of 40Ca+ ions in a two-ion crystal using axial potential modulation in a global gate laser field. We characterize the resulting gate performance via one-qubit randomized benchmarking, applying different random sequences to each co-trapped ion. We identify the primary error sources and compare the results with single-ion experiments to better understand our experimental limitations. These experiments form a foundation for the universal control of two ions, confined in the same potential well, with a single gate laser beam.

Abstract
The difference of the patients bearing hepatocellular carcinoma (HCC) with and without cirrhosis at clinical level has not been completely determined. This study compared their differences in clinicopathological traits and prognostic factors for relapse-free survival (RFS) and overall survival (OS). Animal model was established to validate the result of clinical observation. As a result, 82 patients bearing HCC with no cirrhosis (HCC-NC) and 146 patients bearing HCC with cirrhosis (HCC-C) were included. HCC-NC exhibited shorter prothrombin time and higher plasma albumin than HCC-C. In HCC-NC, satellite nodule was an independent risk factor for OS, and high γ-glutamyl transpeptidase was an independent risk factor for RFS. In HCC-C, female sex was an independent risk factor for OS. Stratified analysis showed the OS and RFS of HCC-NC were better than HCC-C in conditions like without cancer embolus (in the portal vein or bile duct), without lymphadenopathy in hepatic portal, without satellite nodule and with small or high-differentiated tumor. Animal model analysis showed HCC-NC had a higher liver/body weight ratio, less tumor count and smaller max tumor volume than HCC-C. In conclusion, clinicopathological traits and risk factors influencing postoperative OS and RFS differed between patients with HCC-C and HCC-NC.

Abstract
A new, simple, stability-indicating high-performance thin-layer chromatography method was developed for the quantification of 10-hydroxy-2-decenoic acid (10-HDA) in some royal jelly products marketed in Egypt. The used solvent system was chloroform:acetic acid (10:1, v/v) and the bands were measured densitometrically at 210 nm. First- and second-derivative treatments of the data were performed. The present study shows a comparison between three statistical regression methods for handling data: parametric, nonparametric and weighted regression (WR) methods. The developed methods were validated as per International Conference on Harmonization guidelines. To validate the stability-indicating power of the developed analytical method, the royal jelly standard was subjected to forced degradation studies including the effect of hydrolysis, oxidation, photolysis and dry heat. It was found that derivative treatment of the chromatographic response data gives improved quantitation and sensitivity of the chromatographic signals. Weighted regression of the response data is found to be advantageous over the use of both parametric and nonparametric regression models. This was shown by a great enhancement in the accuracy and precision in the analysis of 10-HDA in royal jelly products. The % recovery in case of WR was 99.92 ± 0.16, while % recovery in case of nonparametric and parametric regressions were 99.56 ± 0.25 and 98.63 ± 0.65, respectively.

Abstract
Coronavirus Disease 2019 (COVID-19), which originated in Wuhan, China, has caused many healthcare workers (HCWs) to be infected. Seventy-two HCWs manifested with acute respiratory illness were retrospectively enrolled to analyze the risk factors. The high-risk department, longer duty hours, and suboptimal hand hygiene after contacting with patients were linked to COVID-19.

Published: March 2020

Abstract

Background
Invasive aspergillosis (IA) remains a potentially lethal disease and requires timely diagnosis and initiation of antifungal therapy. Recently, the IMMY lateral flow assay (LFA), the OLM Diagnostics lateral flow device (LFD), and the Wako turbidimetric β-d-glucan assay have been approved for use as a diagnostic aid. However, their performance in diagnosing IA on serum samples from at-risk patients and the added value to the existing detection of serum galactomannan remain to be investigated.

Methods
We prospectively collected serum samples from 239 hematology patients and evaluated the diagnostic performance of these 3 assays while using the 2019 EORTC/MSG definitions (study number S59863/S61797, NCT03004092).

Results
We identified 5 cases of proven IA, 36 cases of probable IA, and 188 controls. The LFA had the highest negative predictive value (NPV) and sensitivity (0.90 and 0.49, respectively) while galactomannan detection had the highest positive predictive value and specificity (0.93 and 0.99, respectively). Sensitivity was not significantly different between both tests. When used in combination, the highest NPV was seen in patients with a negative LFA and a negative β-d-glucan test. The sensitivity of the LFD was significantly lower than the LFA. After omitting serum galactomannan from the definitions to control for incorporation bias, the sensitivity of the LFA outperformed galactomannan detection (0.41 vs 0.31, P = .046).

Conclusions
The LFA is a fast and effective alternative to serum galactomannan detection for the diagnosis of IA and is especially useful for centers with low sample throughputs. The addition of the Wako β-D-glucan assay further improves the diagnostic performance.
Non-Universal Arguments under the European Convention on Human Rights
Authors: Altwicker Tilmann 
Published: March 2020

Abstract
It is popular to view international human rights law as universal. In a normative sense, human rights universality refers to certain qualities of human rights norms. These qualities have long been under attack, most recently by what is called here human rights nationalism. The main point made in this article is that some of the criticism levelled against normative human rights universality can be accommodated through interpretation. To this end, non-universality of human rights is judicially created (argumentative non-universality). This article offers an analysis of argumentative non-universality in the context of the European Convention on Human Rights (ECHR). It shows that the European Court of Human Rights (ECtHR) operationalizes argumentative non-universality through a conception of asymmetric protection, by using context as a difference-making fact and by allowing, in certain cases, for a decentralized interpretation of rights under the ECHR. As argued here, resorting to argumentative non-universality sometimes makes sense because non-universality takes seriously the fact that individual freedom is, to some extent, socially and politically conditioned. Furthermore, non-universality allows for reasonable interpretive pluralism, and it contributes to the institutional legitimacy of the ECtHR. In conclusion, the ECtHR is, rightly so, an ‘interpreter of universality’ (as quoted by Judge Pinto de Albuquerque) as it is an interpreter of the non-universality of convention rights.

ABSTRACT
Globally, the conversion of primary forests to plantations and agricultural landscapes is a common land use change. Kauri (Agathis australis) is one of the most heavily impacted indigenous tree species of New Zealand with &lt;1% of primary forest remaining as fragments adjacent to pastoral farming and exotic forest plantations. By contrasting two forest systems, we investigated if the fragmentation of kauri forests and introduction of pine plantations (Pinus radiata) are significantly impacting the diversity and composition of soil microbial communities across Waipoua kauri forest, New Zealand. Using next generation based 16S rRNA and ITS gene region sequencing, we identified that fungal and bacterial community composition significantly differed between kauri and pine forest soils. However, fungal communities displayed the largest differences in diversity and composition. This research revealed significant shifts in the soil microbial communities surrounding remnant kauri fragments, including the loss of microbial taxa with functions in disease suppression and plant health. Kauri dieback disease, caused by Phytophthora agathidicida, currently threatens the kauri forest ecosystem. Results from this research highlight the need for further investigations into how changes to soil microbial diversity surrounding remnant kauri fragments impact tree health and disease expression.

Abstract
The impairment of the mitochondrial functions is a hallmark of aging. During aging, there is a downregulation of two mechanisms strictly associated with mitochondrial integrity, including the mitonuclear imbalance (eg, imbalance in mitochondrial- versus nuclear-encoded mitochondrial proteins) and the mitochondrial unfolded protein response (UPRmt). Here, we evaluated the effects of aerobic exercise in the mitonuclear imbalance and UPRmt markers in the skeletal muscle of old mice. We combined the physiological tests, molecular and bioinformatic analyzes to evaluate the effects of 4 weeks of aerobic exercise training on mitonuclear imbalance and UPRmt markers in the skeletal muscle of young (2 months) and aged (24 months) C57BL/6J mice. Initially, we found that aging reduced several mitochondrial genes in the gastrocnemius muscle, and it was accompanied by the low levels of UPRmt markers, including Yme1l1 and Clpp mRNA. As expected, physical training improved the whole-body metabolism and physical performance of aged mice. The aerobic exercise increased key proteins involved in the mitochondrial biogenesis/functions (VDAC and SIRT1) along with mitochondrial-encoded genes (mtNd1, mtCytB, and mtD-Loop) in the skeletal muscle of old mice. Interestingly, aerobic exercise induced the mitonuclear imbalance, increasing MTCO1/ATP5a ratio and UPRmt markers in the skeletal muscle, including HSP60, Lonp1, and Yme1L1 protein levels in the gastrocnemius muscle of aged mice. These data demonstrate that aerobic exercise training induced mitonuclear imbalance and UPRmt in the skeletal muscle during aging. These phenomena could be involved in the improvement of the mitochondrial metabolism and oxidative capacity in aged individuals.
The Role of Feed in Aquatic Laboratory Animal Nutrition and the Potential Impact on Animal Models and Study Reproducibility
Authors: Brenes-Soto Andrea , Tye Marc , Esmail Michael Y 
Published: March 2020

Abstract
Feed plays a central role in the physiological development of terrestrial and aquatic animals. Historically, the feeding practice of aquatic research species derived from aquaculture, farmed, or ornamental trades. These diets are highly variable, with limited quality control, and have been typically selected to provide the fastest growth or highest fecundity. These variations of quality and composition of diets may affect animal/colony health and can introduce confounding experimental variables into animal-based studies that impact research reproducibility.

AbstractBackgroundReplacing tenofovir disoproxil fumarate (TDF) with tenofovir alafenamide (TAF) improves renal tubular markers in HIV-infected individuals but the impact on estimated glomerular filtration rate (eGFR) remains unclear.MethodsIn all participants from the Swiss HIV Cohort Study who switched from TDF to TAF-containing antiretroviral regimen or continued TDF, we estimated changes in eGFR and urine protein-to-creatinine ratio (UPCR) after 18 months using mixed-effect models.ResultsOf 3520 participants (26.6% women, median age 50 years), 2404 (68.5%) switched to TAF. Overall, 1664 (47.3%) had an eGFR &lt;90 mL/min and 1087 (30.9%) an UPCR ≥15 mg/mmol. In patients with baseline eGFR ≥90 mL/min, eGFR decreased with the use of TDF and TAF (−1.7 mL/min). Switching to TAF was associated with increases in eGFR of 1.5 mL/min (95% confidence interval [CI], .5–2.5) if the baseline eGFR was 60–89 mL/min, and 4.1 mL/min (95% CI, 1.6–6.6) if &lt;60 mL/min. In contrast, eGFR decreased by 5.8 mL/min (95% CI, 2.3–9.3) with continued use of TDF in individuals with baseline eGFR &lt;60 mL/min. UPCR decreased after replacing TDF by TAF, independent of baseline eGFR.ConclusionsSwitching from TDF to TAF improves eGFR and proteinuria in patients with renal dysfunction.

Abstract

Objectives
To determine antibiotic susceptibility of community-acquired respiratory tract infection (CA-RTI) isolates of Streptococcus pneumoniae and Haemophilus influenzae collected in 2015–17 from Pakistan.

Methods
MICs were determined by CLSI broth microdilution and susceptibility was assessed using CLSI, EUCAST (dose-specific) and pharmacokinetic/pharmacodynamic (PK/PD) breakpoints.

Results
A total of 94 S. pneumoniae and 122 H. influenzae isolates were collected. Susceptibility to penicillin was noted in 23.4% of the S. pneumoniae isolates by CLSI oral/EUCAST low-dose IV breakpoints, although by CLSI IV and EUCAST high-dose breakpoints all isolates were characterized as susceptible. Susceptibility to trimethoprim/sulfamethoxazole (10.6%), macrolides (33%) and cefaclor (28.7%) was low but higher susceptibility was observed to ceftriaxone (100%), amoxicillin and amoxicillin/clavulanic acid (98.9%), cefuroxime (oral, 97.9%), cefpodoxime (96.8%), fluoroquinolones (93.6%–96.8%) and cefdinir (76.6%) by CLSI breakpoints. However, using EUCAST breakpoints, susceptibility to cefpodoxime (70.2%) and cefuroxime (oral, 61.7%) was reduced. H. influenzae isolates were almost all β-lactamase negative (96.7%). Using CLSI breakpoints, ≥93.4% of isolates were susceptible to all antibiotics tested except fluoroquinolones (75.4%–77.1%) and trimethoprim/sulfamethoxazole (41%). The proportion of isolates susceptible using EUCAST breakpoints was similar or identical for penicillins, trimethoprim/sulfamethoxazole and the cephalosporins that have EUCAST breakpoints; the proportion of isolates susceptible using EUCAST breakpoints was similar or identical to that using CSLI breakpoints except for cefuroxime (oral), where only 1.6% of isolates were considered susceptible. Susceptibility of H. influenzae to fluoroquinolones was also lower by EUCAST breakpoints (33.6%–34.4%). The application of different EUCAST breakpoints for low and higher doses for some of the antibiotics (amoxicillin, amoxicillin/clavulanic acid, ampicillin, penicillin, ceftriaxone, clarithromycin, erythromycin, levofloxacin and trimethoprim/sulfamethoxazole) allowed, for the first time in a SOAR study, the effect of raising the dosage on susceptibility to be quantified.

Conclusions
Antibiotic susceptibility in these important respiratory tract pathogens varied in Pakistan based on different breakpoints. These data are important for empirical therapy choices in the treatment of CA-RTIs.
