Abstract
The Singojuruh flash flood incident have diverse effects on residential and agriculture areas. As result of the 2018 flood, two houses collapsed and there were severe also effects on agriculture. This paper focuses on understanding the river capacity (Badeng River) as well as the modeling to the next flood. We used Hydrological Engineering Center-River Analysis System (HEC-RAS) version 5.0.7 to analyze the river storage capacity. The factor in this analysis i.e. river morphometry (river length, river width, river depth and river slope) and manning coefficient. The sampling conducted in three point along the Badeng River. The result showed that each of point location have different characteristic hence influence its capacity. The smallest capacity has the biggest potential of flooding.

Published: January 2020

Abstract
In this work we studied the grain growth and orientation change of CdTe multi-crystallize thin films during chlorine activation. A thermodynamic energy criterion is proposed for finding non-toxic substitutes of cadmium chloride and tested by Monte-Carlo simulation method combined with CASTEP calculation and annealing algorithm. Visualized pixel images of simulation results are in good agreement with experimental results. The mechanism of cadmium chloride for chlorine activation is explained from the aspect of thermodynamics. Predictions of non-toxic chloride substitutes for toxic cadmium chlorine and corresponding annealing routes are given based on the proposed energy criterion and energy calculation results.

Abstract
In the present investigation, Magnesium composites have been fabricated with boron carbide (B4C) as reinforcement by powder metallurgicaltechnique. Two different particle sizes—micro and nano B4C particles with weight percentage of 0%, 5% and 10% has been studied. The green compacts were prepared by cold pressing and then sintering the specimens before being subjected to cold upsetting under triaxial stress state condition in order to study the phenomenon of workability and instantaneous strain hardening index. Powder characterizations are discussed using x-ray Diffraction peaks, Scanning Electron Microscope images and Energy Dispersive Spectrum analysis. Cold upsetting has been preferred to investigate the performance of the composites. The values of formability stress index factor (β

The results reveal that Mg-10% nano B4C composite has higher relative density, formability stress index factor and hence high workability than the other composites. The addition of B4C particles as reinforcement affects the strain hardening index due to geometric and work hardening of the composites.

Published: January 2020

Abstract
We report reversible dynamic behavior of a magnetic liquid metal marble by changing magnetic field polarity. We coated iron (Fe) particles on the surface of the oxidized liquid metal by HCl-based chemical reaction to make it to be magnetized and to be non-wettable. We utilized electromagnets and changed current direction on-demand to change the magnetic polarity of the electromagnet. In 1-dimension (1-D), with an applied magnetic field of reverse polarity from the bottom, the conventional wetting shape of the magnetic liquid metal marble was observed, whereas the split was occurred with the applied magnetic field of same polarity due to attractive or repulsive force. With an applied magnetic field of reverse polarity, the split marbles was merged. By removing the magnetic field, the deformed magnetic liquid metal marble was recovered. The applied current dependent deformability and recoverability, and split and merge time were investigated. In addition, in 2-dimension (2-D), we observed various deformations and split behavior of the magnetic liquid metal marble with various magnetic field polarity combinations by utilizing electromagnets, which is reversible.

Published: January 2020

Abstract
Due to the excellent electrical transmission and potentially excellent thermoelectric (TE) performance, digenite (Cu1.8S) has attracted more attentions. The combination of mechanical alloying (MA) and spark plasma sintering (SPS) was widely used in preparing Cu1.8S bulk material, while the TE properties for pure sample were still low. Therefore, it’s worth to search a suitable synthesis method to enhance the thermoelectric performance for pristine Cu1.8S material. In this study, high-density bulk samples of copper sulfide (CS) were fabricated by solid states reaction method combined with SPS at different temperatures. When the SPS temperature was over 873 K, large amounts of sulfur volatilization lead to the appearance of Cu1.96S second phase and it was considered to have great influence on the thermoelectric performances. The result reveals that the increased sintering temperature could affect the density and grain size of the bulk samples. The highest ZT value of 0.54 was obtained at 773 K for the sample sintered at 773 K, which is also the highest ZT value for the pristine Cu1.8S in the literature.

Published: January 2020

Abstract
The capture barrier energy of the E-center deep level defect introduced in Pd/Sb-doped Ge by alpha-particle irradiation has been studied. Palladium Schottky barrier diodes (SBDs) fabricated by resistive evaporation technique were successfully characterised by current-voltage (I-V), capacitance-voltage (C-V), conventional and Laplace deep level transient spectroscopy. The rectification quality of Schottky contacts before and after irradiation was confirmed by I-V and C-V results. The ideality factor and doping density were determined to be in the range of 1.23 to 1.46 and 3.55 × 1015 to 5.25 × 1015 cm−3, respectively before and after irradiating the device with alpha-particles. The thermal emission activation energy and the apparent capture cross section of the E-center were determined from the Arrhenius plot to be 0.37 eV and 1.3 × 10−15 cm2, respectively. The capture barrier energyand the true capture cross section of the E-center were calculated to be 0.052 eV and 2.25 × 10−17 cm2, respectively from the experimental findings after varying the pulse width at different temperature range from 145 to 180 K in steps of 5 K.

Published: January 2020

Abstract
This research paper portrays the enrichment of mechanical, wear and corrosion properties of the Aluminium 6061 matrix composite by incorporating hybrid reinforcements. Aluminium 6061 alloy is stir casted with different proportions of boron nitride (BN), Aluminium oxide (Al2O3) and graphite particles. Tensile test reveals that the tensile strength and ductility for the Al 6061-30 BN -10Al2O3- 5C is improved due to the presence of higher BN content along with 10% Al2O3. Significant improvement in microhardness (63HV), compressive strength (187 Pa) and impact strength (12 J) for the Al 6061-30 BN -10Al2O3- 5C when compared with the bare Al 6061 alloy. The dispersion of BN with Al2O3 improved the wear resistance for the Al 6061-30 BN -10 Al2O3- 5 C composite, where as the unreinforced bare Al alloy has caused the major surface degradation resulting in poor wear property and the worn out surfaces are examined through the scanning electron microscope. The main wear mechanism is identified as adhesive wear. The corrosion test results clearly reveals that the corrosion resistance is higher for the Al 6061-30 BN -10Al2O3- 5C (−0.526 ± 0.004 V) with a lower current density of −0.983 ± 0.004 μA cm−2 than the other composites and bare Al 6061.

Published: January 2020

Abstract
Porous nanofibers are of great significance to different applications. Herein, interconnected macroporous nanofibers were electrospun from polystyrene (PS)/chlorobenzene (CB)/N’N-dimethylformamide (DMF) using a bath collector. The effects of the solvent ratio and bath collector temperature on the structure of PS fibers are studied. The results showed that the presence of CB is essentials for the formation of porous fibers. Furthermore, the size of the pores on the surface of fibers increases by increasing the ratio of CB as well as decreasing the temperature of the bath collector. The formation mechanism of the interconnected macroporous structure is discovered. The BET test showed that these fibers had an outstanding specific surface area (SSA) of ~44.27 m2 g−1. We believe our findings can be used as a good reference for the generation of electrospun nanofibers with interconnected macroporous using a water bath as a collector.

Abstract
Bio-molecule capped α-MnO2 nanoparticles have been successfully synthesized from the reduction of KMnO4 via a facile green synthesis route using an aqueous leaf extract of Bryophyllum pinnatum as a reducing and capping agent. The synthesized α-MnO2 nanoparticles were characterized by x-ray diffraction (XRD), Fourier transform—infrared (FT-IR), energy dispersive x-ray (EDX), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), thermogravimetric (TG) and differential scanning calorimetry (DSC) techniques. Experimental results clearly demonstrate the successful synthesis of bio-molecule capped crystalline tetragonal α-MnO2 nanoparticles with the size of 4–18 nm. The magnetic property of the product was evaluated using a vibrating sample magnetometer (VSM) and the result reveals that the presently synthesized bio-molecule capped α-MnO2 nanoparticles exhibit ferromagnetic property at room temperature.
Calculation and comparison on fracture toughness of specific reliability between ASTM and ISO standards
Authors: Zhang Si , Zhou Sizhu , Li Meiqiu , Fu Biwei 
Published: January 2020

Abstract
Fracture toughness, as a crucial mechanical property, is essential in the research of fatigue crack propagation and fatigue life. Considering the enormous data scatter of the fracture toughness in experiments, a data processing method is proposed to calculate the fracture toughness for the specified reliability. Based on the traditional data processing method shown in the relative standards, the two-dimensional, one-sided tolerance factor is introduced to calculate the influence of the reliability. In addition, by comparing the data processing methods of the fracture toughness presented in the ISO12135:2016 and ASTM E1820-2013 standards, the differences between them were mainly the range of the qualified data, the function of the construction line, and the equation of the regression line. Because the construction lines of the two standards are based on two different material constitutive models, if the constitutive model of material is more aligned with that of the ideal elastic plastic material, the ASTM E1820-2013 standard is recommended; otherwise, the ISO12135:2016 standard is recommended. For 30CrNi2MoVA, the ISO 12135:2016 standard was more suitable, and the error of the JIC obtained by the two standards was about 5%.
Strong correlation between mobility and magnetoresistance in Weyl and Dirac semimetals
Authors: Singh Sukriti , Süβ Vicky , Schmidt Marcus , Felser Claudia , Shekhar Chandra 
Published: January 2020

Abstract
The discovery of Weyl and Dirac fermions in solid systems is a recent major breakthrough in the field of condensed matter physics. These materials exhibit extraordinary properties in terms of carrier mobility and magnetoresistance (MR). These two quantities are highly dependent in the Weyl semimetal transition monopnictide family, i.e. NbP, TaP, NbAs, and TaAs. Furthermore, the gathered mobility and MR (or slope of MR) at 2 K in 9 T of other well-known Weyl and Dirac semimetals follow a relation similar to the right turn symbol, i.e. the MR increases rapidly with mobility; thereafter it begins to saturate after reaching a value of 103. This suggests a nonlinear dependency. Nevertheless, for materials possessing high carrier mobility, it is valid to expect high MR.

Published: January 2020

AbstractObjectivesPrimary cutaneous clear cell sarcoma (PCS) is a rare malignancy and difficult to differentiate from melanoma. We investigated factors influencing survival and recurrence.MethodsAn institutional cancer registry and literature search were used for a retrospective study. Only clear cell sarcoma cases with a primary site of skin and subcutaneous tissue were included. Kaplan-Meier and Cox regression analyses were used to assess survival time and hazard ratios.ResultsThree eligible cases were identified at our institution. In addition, the PubMed and Google Scholar reviews identified 1,878 items, with 23 patients with PCS. The median age was 25 years with 62% female. The tumors ranged in size from 0.4 to 4.5 cm. Cytogenetics showed t(12;22)(q13;q12) in all cases and a unique variant of t(2;22)(q32.3;q12) in one case. Surgery was the most common treatment, followed by chemotherapy/radiation. PCS recurred in 46% of patients with a median relapse-free survival time of 15 months. Only two known PCS-related mortalities were recorded, at 38 and 60 months following initial diagnosis. Smaller tumor size and negative sentinel lymph node biopsy (SLNB) status were significantly associated with a better disease-free survival.ConclusionsTumor size and SLNB status influence PCS survival and recurrence. More research is needed due to the rarity of this disease.

Published: January 2020

Abstract

Objectives
The study explored job stress, burnout, work-life balance, well-being, and job satisfaction among pathology residents and fellows. The aims were to examine the prevalence and sources of stress and burnout, as well as identify resources to promote work-life balance and well-being and prevent burnout.

Methods
The study used a cross-sectional survey deployed online to a large national sample of pathology residents and fellows.

Results
Job stress and burnout were prevalent, with more than a third of the respondents reporting that they were currently experiencing burnout. The respondents, particularly residents, were struggling with academics, and higher percentages were struggling with work-life balance and emotional well-being. Overall, the majority of respondents who rated their work-life balance indicated that it was poor or fair. Among the factors contributing to job stress and burnout and detracting from work-life balance, workload was the leading factor.

Conclusions
The factors contributing to job stress and burnout included organizational factors such as workload, value, and aspects of the learning environment, as well as personal factors such as work-life integration. One of the overarching implications is the need to address a range of interdependent considerations in designing resources to reduce job stress, promote work-life balance, and prevent burnout.

AbstractObjectivesINSM1 has been described as a sensitive and specific neuroendocrine marker. This study aims to compare INSM1 with traditional neuroendocrine markers in gastrointestinal neuroendocrine neoplasms.MethodsRetrospective review (2008-2018) was used to retrieve paraffin-embedded tissue from 110 gastrointestinal neuroendocrine neoplasms and controls that was subsequently stained with INSM1, synaptophysin, chromogranin, CD56, and Ki-67.ResultsINSM1 was positive in 16 of 17 (94.1%) gastric, 17 of 18 (94.4%) pancreatic, 13 of 18 (72.2%) small bowel, 17 of 21 (81.0%) colonic, and 26 of 36 (72.2%) appendiceal tumors. INSM1 was positive in 58 of 70 (82.9%) well-differentiated neuroendocrine tumors, 17 of 20 (85.0%) poorly differentiated neuroendocrine carcinomas, 8 of 11 (72.7%) low-grade goblet cell adenocarcinomas (grade 1), and 6 of 9 (66.7%) high-grade goblet cell adenocarcinomas (grade 2/3). INSM1 sensitivity for neuroendocrine neoplasms (80.9%) was less than that of synaptophysin (99.1%), chromogranin (88%), and CD56 (95.3%); specificity was higher (95.7% vs 86.0%, 87.3%, and 86.0%, respectively).ConclusionsINSM1 is a useful marker of neuroendocrine differentiation in gastrointestinal neuroendocrine and mixed neuroendocrine neoplasms. Compared with traditional neuroendocrine markers, INSM1 is less sensitive but more specific.

Abstract

Summary
Segmentation of single cells in microscopy images is one of the major challenges in computational biology. It is the first step of most bioimage analysis tasks, and essential to create training sets for more advanced deep learning approaches. Here, we propose 3D-Cell-Annotator to solve this task using 3D active surfaces together with shape descriptors as prior information in a semi-automated fashion. The software uses the convenient 3D interface of the widely used Medical Imaging Interaction Toolkit (MITK). Results on 3D biological structures (e.g. spheroids, organoids and embryos) show that the precision of the segmentation reaches the level of a human expert.

Availability and implementation
3D-Cell-Annotator is implemented in CUDA/C++ as a patch for the segmentation module of MITK. The 3D-Cell-Annotator enabled MITK distribution can be downloaded at: www.3D-cell-annotator.org. It works under Windows 64-bit systems and recent Linux distributions even on a consumer level laptop with a CUDA-enabled video card using recent NVIDIA drivers.

Published: January 2020

Abstract

Motivation
Liquid chromatography–mass spectrometry (LC-MS) is a standard method for proteomics and metabolomics analysis of biological samples. Unfortunately, it suffers from various changes in the retention times (RT) of the same compound in different samples, and these must be subsequently corrected (aligned) during data processing. Classic alignment methods such as in the popular XCMS package often assume a single time-warping function for each sample. Thus, the potentially varying RT drift for compounds with different masses in a sample is neglected in these methods. Moreover, the systematic change in RT drift across run order is often not considered by alignment algorithms. Therefore, these methods cannot effectively correct all misalignments. For a large-scale experiment involving many samples, the existence of misalignment becomes inevitable and concerning.

Results
Here, we describe an integrated reference-free profile alignment method, neighbor-wise compound-specific Graphical Time Warping (ncGTW), that can detect misaligned features and align profiles by leveraging expected RT drift structures and compound-specific warping functions. Specifically, ncGTW uses individualized warping functions for different compounds and assigns constraint edges on warping functions of neighboring samples. Validated with both realistic synthetic data and internal quality control samples, ncGTW applied to two large-scale metabolomics LC-MS datasets identifies many misaligned features and successfully realigns them. These features would otherwise be discarded or uncorrected using existing methods. The ncGTW software tool is developed currently as a plug-in to detect and realign misaligned features present in standard XCMS output.
