Published: July 2019

AbstractIn this work we report a facile route to grow large area, uniform, continuous and few-layer α-In2Te3 film via chemical vapor deposition (CVD) methods. The characterizations show the large area of CVD-grown few-layer α-In2Te3. This method guarantees the precise control of thickness down to few layers and large area preparation. The magnetoresistance (MR) properties of few-layer In2Te3 was investigated from 2 to 300 K and its MR stability under long exposure to ambient air was studied for the first time. Few-layer of α-In2Te3 shows a positive MR and the largest transverse MR was observed to about 11% at 2 K and a high stability of MR to long time exposure in air up to 21 weeks.

Abstract
Lupus nephritis (LN) leads to chronic kidney disease (CKD) through progressive fibrosis. Mycophenolate inhibits inosine monophosphate dehydrogenase and is a standard treatment for LN. The mammalian or mechanistic target of rapamycin (mTOR) pathway is activated in LN. Rapamycin inhibits mTOR and is effective in preventing kidney transplant rejection, with the additional merits of reduced incidence of malignancies and viral infections. The effect of mycophenolate or rapamycin on kidney fibrosis in LN has not been investigated. We investigated the effects of mycophenolate and rapamycin in New Zealand Black and White first generation (NZB/W F1) murine LN and human mesangial cells (HMCs), focusing on mechanisms leading to kidney fibrosis. Treatment of mice with mycophenolate or rapamycin improved nephritis manifestations, decreased anti-double stranded (ds) DNA antibody titer and reduced immunoglobulin G (IgG) deposition in the kidney. Both mycophenolate and rapamycin, especially the latter, decreased glomerular mTOR Ser2448 phosphorylation. Renal histology in untreated mice showed mesangial proliferation and progressive glomerulosclerosis with tubular atrophy, and increased expression of transforming growth factor β1 (TGF-β1), monocyte chemoattractant protein-1 (MCP-1), α-smooth muscle actin (α-SMA), fibronectin (FN) and collagen. Both mycophenolate and rapamycin ameliorated the histopathological changes. Results from in vitro experiments showed that both mycophenolate and rapamycin decreased mesangial cell proliferation and their binding with anti-dsDNA antibodies. Mycophenolate and rapamycin also down-regulated mTOR and extracellular signal-regulated kinase (ERK) phosphorylation and inhibited fibrotic responses in mesangial cells that were induced by anti-dsDNA antibodies or TGF-β1. Our findings suggest that, in addition to immunosuppression, mycophenolate and rapamycin may reduce fibrosis in LN, which has important implications in preventing CKD in patients with LN.

Published: July 2019

Context. Worldwide very long baseline radio interferometry (VLBI) arrays are expected to obtain horizon-scale images of supermassive black hole candidates and of relativistic jets in several nearby active galactic nuclei. This, together with the expected detection of electromagnetic counterparts of gravitational-wave signals, motivates the development of models for magnetohydrodynamic flows in strong gravitational fields.
Aims. The Black Hole Accretion Code (BHAC) is a publicliy available code intended to aid with the modeling of such sources by performing general relativistic magnetohydrodynamical simulations in arbitrary stationary spacetimes. New additions to the code are required in order to guarantee an accurate evolution of the magnetic field when small and large scales are captured simultaneously.
Methods. We discuss the adaptive mesh refinement (AMR) techniques employed in BHAC, which are essential to keep several problems computationally tractable, as well as staggered-mesh-based constrained transport (CT) algorithms to preserve the divergence-free constraint of the magnetic field. We also present a general class of prolongation operators for face-allocated variables compatible with them.
Results. After presenting several standard tests for the new implementation, we show that the choice of the divergence-control method can produce qualitative differences in the simulation results for scientifically relevant accretion problems. We demonstrate the ability of AMR to decrease the computational costs of black hole accretion simulations while sufficiently resolving turbulence arising from the magnetorotational instability. In particular, we describe a simulation of an accreting Kerr black hole in Cartesian coordinates using AMR to follow the propagation of a relativistic jet while self-consistently including the jet engine, a problem set up for which the new AMR implementation is particularly advantageous.
Conclusions. The CT methods and AMR strategies discussed here are currently being used in the simulations performed with BHAC for the generation of theoretical models for the Event Horizon Telescope collaboration.

Context. The tip-tilt stabilisation system of the 1.8 m Auxiliary Telescopes of the Very Large Telescope Interferometer was never dimensioned for robust fringe tracking, except when atmospheric seeing conditions are excellent.
Aims. Increasing the level of wavefront correction at the telescopes is expected to improve the coupling into the single-mode fibres of the instruments, and enable robust fringe tracking even in degraded conditions.
Methods. We deployed a new adaptive optics module for interferometry (NAOMI) on the Auxiliary Telescopes.
Results. We present its design, performance, and effect on the observations that are carried out with the interferometric instruments.

Published: July 2019

Abstract
Objective Probiotic supplementation can help to improve recovery from jaundice by reducing enterohepatic circulation through the regulation of intestinal microbial flora. The aim of our study was to investigate the effect of probiotic supplementation on neonatal hyperbilirubinemia caused by isoimmunization alone.
Study Design Sixty neonates were randomly divided into a placebo group and a probiotic group (Lactobacillus rhamnosus GG). Serum total bilirubin (STB) levels were measured at birth and at 4, 8, 16, 24, and 36 hours of treatment (and at 48, 60, and 72 hours if necessary). Duration of phototherapy, rephototherapy requirements, and daily meconium evacuation were recorded.
Results STB and rebound STB levels at 36 hours were lower in the probiotic group than in the placebo group (p = 0.01 and p = 0.006, respectively). Meconium evacuation was more frequent in the probiotic group than in the placebo group on the second and third days of life (p = 0.002 and 0.009, respectively).
Conclusion Probiotics do not affect STB levels in the first 24 hours of life or duration of phototherapy in neonates with jaundice caused by blood group incompatibility. The effect of probiotic supplementation by reducing enterohepatic circulation occurs at 36 hours of life in newborns with isoimmunization.

Published: July 2019

Objective Our objective was to evaluate the impact of a quality improvement (QI) initiative on the regional anesthesia placement-to-infant delivery time during cesarean delivery (CD).
Study Design We performed a quality improvement trial. Before June 18, 2018, the preoperative protocol was as follows: the anesthesiologist administered regional anesthesia in the operating room then the nurse placed the Foley's catheter, clipped pubic hair, precleaned the abdomen, and abdominal preparation. On June 18, 2018, the protocol changed and all the preoperative preparation (Foley's clip and preclean) were performed prior to the arrival in the operating room. The records of patients who underwent scheduled or nonemergency CD between May 1 and July 15, 2018, were reviewed. Our primary outcome was time between the placements of regional anesthesia to infant delivery at the time of CD. Bivariate and multivariable analyses were performed.
Results A total of 194 patients were included, 124 before and 70 after the process change. The change in process leads to a significant reduction in anesthesia-to-delivery time, even after adjusting for number of prior CD and body mass index (BMI). Other times were also significantly impacted by the change.
Conclusion Our QI initiative significantly decreased the time from anesthesia placement to delivery of the fetus. Performing preoperative preparation activities, such as Foley's placement and shaving, after regional anesthesia for CD, increase the risk of fetal exposure to maternal hypotension. We evaluated the impact of a QI initiative on regional anesthesia placement to infant delivery time during CD.

Published: July 2019

AbstractRuptures of the anterior cruciate ligament (ACL) typically occur in professional football and epidemiological data about longitudinal injury development is needed. This practice‐driven investigation of media‐derived ACL data provides information about professional football over 10 years. Injury registration was based on “kicker” sports magazine information that have been recorded over one decade in a standardized manner. Only ACL ruptures in the first German football league were included when they could be verified by a second reliable source. Level of evidence: III. Fifty‐seven primary ACL ruptures were verified in the first German football league during the seasons 2007/2008 to 2016/2017. Among them, six re‐injuries were found. Mean age at the time of injury was 24.8 years (SD 3.8). 31% (n = 20) of ACL ruptures occurred at the beginning of the season in August or September (p = 0.02). Mean time of RTC after primary ACL ruptures was 226.7 days (SD: 93.5) and 245.6 days (SD: 45.4) after re‐injury. Although 62 (98%) players returned to football after injury and only one player immediately finished his career, 54.9% of the affected individuals played 3 years after the ACL rupture in the same league. ACL ruptures lead to longer absence than 7 months from football but does not give reason for immediate career‐ending. The decrease in playing level after 3 years illustrate the serious consequences of ACL ruptures in football. Media‐based injury reports may provide interesting information.
Collective operations can extremely reduce work fluctuations
Authors: Perarnau-Llobet Martí , Uzdin Raam

Abstract
We consider work extraction from N copies of a quantum system. When the same work-extraction process is implemented on each copy, the relative size of fluctuations is expected to decay as

can be obtained almost deterministically by globally processing a few copies of the state. This is derived in the two canonical scenarios for work extraction: (i) in thermally isolated systems, where

Abstract
Based on economic nomenclature of Indonesian food crops, corn is the second important commodity after rice. The high corn production correlates with corncob waste produced. The existence of corncob waste is abundant and continuous post-harvest. One alternative to utilize of corncob waste is the high content of cellulose processed to cellulose-based nano hydrogel. In this study, cellulose from corncob was processed into hydrogel by gamma irradiation. Cellulose size reduction is done by the wet milling process. The treatment tested of nano hydrogel control was cellulose dissolved in NaOH/PEG solvent whereas the ratio of cellulose: solvent was 1:2 and 1:4 and nano hydrogel by gamma irradiation that nano-cellulose solution was filtered by vacuum filtration. The aim of this research was to find out the characteristics of nano hydrogel by gamma irradiation. Parameters observed were swelling ratio, gel fraction, texture and morphology. The result showed that the treatment test of nano hydrogel without gamma radiation has 111% and 127% swelling ratio, meanwhile, nano hydrogel with gamma irradiation has a 214% swelling ratio, 99% gel fraction and 1.17 mJ hardness with morphology showed higher porosity. The higher swelling ratio of nano hydrogel by gamma irradiation has the potential for application in agriculture as water absorbent material and fertilizer carrier agent.

Published: July 2019

AbstractNutrition addition in Microbial Enhanced Oil Recovery (MEOR) application is one of the methods used to increase oil production. Nutrition injection in MEOR application must be done carefully because the lack of proper nutrition addition can induce biofilm and biocorrosion formation. The composition of biostimulation medium for optimizing beneficial indigenous bacterial growth in Microbial Enhanced Oil Recovery (MEOR) was evaluated using Response Surface Methodology (RSM) with Central Composite Design (CCD). Three main factors for the medium composition were molasses, Diammonium Phosphate (DAP), and NPK. The RSM was used to know the most effective medium composition towards biofilm production and strength that high potential leads to biocorrosion. Molasses, NPK, and diammonium phosphate (DAP) are utilized as carbon, nitrogen, and phosphate supplementary substrate in Brine water as basal medium. Molasses concentration was 0%-10% while DAP and NPK was 0%-0.5%. Both aerobic and anaerobe sessile bacteria, as well as acid producing bacteria, were enumerated by total plate and turbidity methods. Statistical analysis with α=0.05 proves molasses give significance effect to biofilm strength and sessile anaerobic bacteria. DAP gives significance effect to biofilm strength and sessile aerobic and anaerobic bacteria. NPK give significance effect to sessile anaerobic bacteria. Molasses addition decrease brine pH by microbial activity, make the carbon steel coupon ST-37 corrosion rate increased. Meanwhile, the addition of DAP increased the pH of brine medium and decrease the corrosion rate.

Published: July 2019

Abstract
One way to improve the accuracy of predictive modeling is by combining the models. This research tries to study local cascade. It combined one or more base classifier sequentially. In each stage, the probability prediction of the base classifier was inserted to the data. The data then modeled using a decision tree algorithm. This process continued until the data is homogenous. In the original method, the base classifier used was non-ensemble classifier. Our study included bagging, boosting, and random forest as base classifiers. 11 dataset with binary response was used to assess the accuracy of this method. We also compared the accuracy of our method with others that were published between 1996 and 2009. We found that cascading ensemble classifier slightly improve accuracy and performed better for a dataset with numerical predictors.

Abstract
Bio-photovoltaic is one of the energy-transfer technology that uses oxygenic photoautotrophic organisms to harvest light energy and generate electricity. The aerobic phototropic organisms such as blue-green algae primarily absorb solar energy in visible light areas (400-700 nm). The design of a bio-photovoltaic prototype cell can be constructed using electrodes and Cyanobacteria put inside a plastic container. When the cell is irradiated the photosynthetic reactions will run and produce free electrons. Based on a previous result it is possible to put the cathodes inside the chamber or outside the chamber. In this research, the anode was variated using copper, stainless steel, and zinc. For the measurement while all of the electrodes are in the chamber the efficiency value of each metal is 0.094%; 0.3475%; 4.1026% with the fill factor value of each metal is 0.5719; 0.4204; 0.5776. On the other hand, when one of the electrodes is outside the chamber efficiency value of each metal is 0.0058%; 0.4949%; 1.3013% and the fill factor value of each metal is 0.5559; 0.3519; 0.4564.
