Authors: Whelan Anna , Izewski Joanna , Berkelhammer Charles , Walloch Jami , Kay Helen H. 
Published: August 2020

Abstract
Background Drug-induced liver injury is a common cause of transaminitis, occurring in up to 5% of patients who are hospitalized for liver failure. In pregnancy, transaminitis is seen in conditions which may require expedited delivery.
Case A 39-year-old G2P0010 at 272/7 weeks' gestation with chronic hypertension on labetalol was found to have elevated transaminases. Evaluation for preeclampsia, acute fatty liver, nonalcoholic steatohepatitis, cholelithiasis, infections, and autoimmune conditions were all negative. Labetalol was then discontinued, and liver biopsy was performed. After discontinuation of labetalol, her hepatitis improved, and she was discharged on hospital day 12 and went on to deliver at term.
Conclusion Labetalol-induced hepatitis should be considered in the differential for transaminitis during pregnancy to prevent iatrogenic preterm delivery.

Published: August 2020

Abstract
Background Nasoalveolar molding (NAM) has been extensively used as a presurgical technique in the treatment of unilateral cleft lip and palate (UCLP) over the last two decades. It has proven to be a useful tool to reduce the cleft size, improve nasal symmetry, and increase the columellar length. The long-term stability of these findings has not been conclusively proven.
Methods In this longitudinal study, the nasal symmetry of 24 NAM treated UCLP patients was evaluated to assess the 5-year stability of NAM. The basal photographs were shot postcheiloplasty (T1), at 1-year follow-up (T2), at 3-year follow-up (T3), and 5-year follow-up (T4) appointments.
Results In this study, we found that NAM was a useful adjuvant in achieving nasal symmetry in patients with UCLP in the immediate postoperative period. However, as the patients aged, there was a gradual loss of mean nasal height (by 22.83%) and columella length (by 24.89%), a mean gain in nasal width (by 40.25%) and alar base width (by 40.69%), and an increase in the columella deviation (by 3.46%) from the T1 to the T4 follow-up.
Conclusion Although there is no conclusive evidence, the loss of symmetry may be due to the unequal growth on the cleft and noncleft sides. These patients will be followed-up till end of growth for a definite conclusion on the long-term effect of NAM.

Authors: Kavanagh Maeve A. , Karlsson Joshua K. G. , Colburn Jonathan D. , Barter Laura M. C. , Gould Ian R. 
Published: August 2020

Significance
Examining the excited states of the Photosystem II reaction center furthers our understanding of available charge separation pathways that lead to successful photosynthesis. Our results comprise the largest complete model of the Photosystem II reaction center to be described using time-dependent density functional theory reported in the literature to date. We reveal the molecular orbitals contributing to the excited states that are precursors to charge separation. We demonstrate that our model can successfully predict the action of specific mutations, a valuable tool for the agricultural industry. These models may also be beneficial in informing the design of artificial photosynthetic complexes as well as enhanced bioengineered photosystems.
Cognitive control increases honesty in cheaters but cheating in those who are honest

Published: August 2020

SignificanceConsidering the immense economic costs associated with dishonest behavior, such as tax evasion or music piracy, reducing dishonesty is of great relevance to policy-makers. However, targeting dishonesty with interventions requires a thorough understanding of the underlying (neuro)cognitive processes. We combine neuroimaging with a task that pioneers in measuring the neural mechanisms underlying (dis)honesty. While replicating previous findings that greed drives dishonesty, we reveal that self-referential thinking processes promoted honest behavior. Moreover, we found that cognitive control does not serve the same purpose across individuals but facilitates honest decisions for cheaters, whereas it enables cheating for honest participants. We thus observe that different processes prevent dishonesty for different individuals, which can prove instrumental in the development of more effective interventions.
A global view on how local muscular fatigue affects human performance

Published: August 2020

Significance
The human body is an organism with interdependent systems, where phenomena or interventions in a specific region can provoke responses in another apparently unrelated one. Localized muscle fatigue is characterized as a failure in the production of strength in a specific region caused by overuse. To investigate the global effect of this failure, access to interactions between different regions and systems is needed. In this work, we propose a global multivariate model based on artificial neural networks that produces as output a general functional profile, built from information from different control systems, which allows us to access the effects of local muscle fatigue on tasks that imply body performance as a single system.
Measurement of groove depth standards in the range 1 μm up to 1 mm (EURAMET project 1407)

Published: August 2020

A comparison measurement between 10 national metrology institutes on two types of depth setting standards was conducted using mostly tactile but also two optical instruments for measurement. Three etched silicon standards with depths of 5, 20 and 50 μm and one diamond turned nickel coated copper standard with depths of 200, 600 and 900 μm were measured. The cross section of the grooves was trapezoidal. Most of the participants confirmed their CMC entries. Since many measurements had to be made, contamination of the standards and heavy wear on the standards were also observed after the comparison was completed. The wear consists of indentation marks from stylus instruments on both types of standards and as many as 70 scratch marks on the nickel coated copper artefact used. This indicates that the contact pressure of the tactile measuring devices used by some partners was too high. This can be caused by a too high probing force or a too small probing tip radius. Thus, for future comparisons the actual probing force and actual tip radius need to be measured during the comparison by the participants to assure that the recommended values (2 μm tip radius and 0.7 mN probing force) are not exceeded. The recently published German standard DIN 32567-3 "Determination of the influence of materials on the optical and tactile dimensional metrology - Part 3: Derivation of correction values for tactile measuring devices" describes methods to do both.

Conical defects and holography in topological AdS gravity
Authors: Kastikainen Jani 
Published: August 2020

Abstract
We study codimension-even conical defects that contain a deficit solid angle around each point along the defect. We show that they lead to delta function contributions to Lovelock scalars and we compute the contribution by two methods. We then show that these codimension-even defects appear as Euclidean brane solutions in higher dimensional topological AdS gravity which is Lovelock–Chern–Simons gravity without torsion. The theory possesses a holographic Weyl anomaly that is purely of type-A and proportional to the Lovelock scalar. Using the formula for the defect contribution, we prove a holographic duality between codimension-even defect partition functions and codimension-even brane on-shell actions in Euclidean signature. More specifically, we find that the logarithmic divergences match, because the Lovelock–Chern–Simons action localizes on the brane exactly. We demonstrate the duality explicitly for a spherical defect on the boundary which extends as a codimension-even hyperbolic brane into the bulk. For vanishing brane tension, the geometry is a foliation of Euclidean AdS space that provides a one-parameter generalization of AdS–Rindler space.
Can a sample having zero net magnetization produce polarized spin current?
Authors: Gupta Debjani Das , Maiti Santanu K 
Published: August 2020

Abstract
Antiferromagnetic materials can be the suitable functional elements for designing of future spin based electronic devices, circumventing the use of conventional ferromagnetic materials and spin–orbit coupled systems. In the present work first time we put forward the underlying physical mechanism, to the best of our knowledge, to generate polarized spin current through a magnetic material having zero net magnetization. Our proposal is substantiated by considering a 2D geometry which is composed of several concentric 1D rings where neighboring rings are mutually connected with each other. The misalignment of up and down spin bands, which is the primary requirement to have finite spin polarization, is described analytically and then several aspects of spin polarization are studied numerically. Finally, we discuss experimental realization of the proposed magnetic quantum system. Our analysis can be utilized to any other complicated magnetic geometries, and may open up a new platform for future spintronic applications.
High enhancement factor of SERS probe based on silver nano-structures deposited on a silica microsphere by laser-assisted photochemical method

Published: August 2020

Abstract
The high enhancement factor (EF) of surface-enhanced Raman (SERS) probes is an important parameter for high-sensitivity Raman scattering measurement applied to environment control. In this article, we present a SERS probe based on silver nano-structures deposited on silica microsphere surfaces made by the laser-assisted photochemical method and reflection converging mirror for a high EF Raman measurement of ultralow organic compound concentration inliquid environments. The laser-assisted photochemical method can synthesize and homogeneously deposit nano-silvers on a silica microsphere, and the reflection converging mirror can collect more Raman signal to the photo-detector and give high Raman enhancement of the SERS probe. The SERS-activity of the probe is verified by the detection of ultralow concentrations of Rhodamine 6 G in aqueous solutions in the range of 10−4–10−10 M. The obtained results show that the proposed SERS probe has an increase of collected Raman intensity up to 32% in comparison to a SERS probe without reflection converging mirror, and an EF of the SERS probe achieved up to 1.8 × 1010. We believe that the novel SERS probe has a large potential for applications in biochemical sensing techniques.

Published: August 2020

Abstract
Radiation-induced defects are the significant cause of radiation damage in austenitic stainless steels. In this work, the interactions between a screw dislocation and stacking fault tetrahedrons (SFTs) are studied in Fe–10Ni–20Cr (a model alloy of austenitic stainless steel) and Ni, using molecular dynamics simulations. Four interaction processes were primarily found, including (1) partial absorption, (2) sheared, (3) bypassing, and (4) restored through double cross-slip. In Fe–10Ni–20Cr alloys, there is almost no correlation between the critical resolved shear stress (CRSS) value and SFT size, but the intersection position largely impacts the results. And the CRSS value decreases with temperature increasing in Fe–10Ni–20Cr. The occurrence of cross-slip has a significant effect on the interactions, and there exist greater CRSS value in the interactions of cross-slipping. Besides, the occurrence of the cross-slip is linked to the stacking fault energy and the distribution of solute atoms of the alloys.
Kerr effect anomaly in magnetic topological insulator superlattices

Published: August 2020

Abstract
We report the magneto-optical Kerr effect (MOKE) study of magnetic topological insulator superlattice films with alternating transition-metal and rare-earth doping. We observe an unexpected hump in the MOKE hysteresis loops upon magnetization reversal at low temperatures, reminiscent of the topological Hall effect (THE) reported in transport measurements. The THE is commonly associated with the existence of magnetic skyrmions, i.e. chiral spin textures originating from topological defects in real space. Here, the observation of the effect is tied to ferromagnetic ordering in the rare-earth-doped layers of the superlattice. Our study may provide a new approach for the non-invasive optical investigation of skyrmions in magnetic films, complementary to electrical transport measurements, where the topological Hall signal is often the only hint of non-trivial magnetization patterns.

Published: August 2020

AbstractGraphene decorated with graphitic nanospheres functionalized with pyrene butyric acid (PBA) is used for the first time to fabricate a DNA biosensor. The electrode was formed by attaching a DNA probe onto PBA, which had been stacked onto a graphene material decorated with graphene nanospheres (GNSs). The nanomaterial was drop-coated onto a carbon screen-printed electrode (SPE) to create the GNS-PBA modified electrode (GNS-PBA/SPE). A simple method was used to produce GNS by annealing graphene oxide (GO) solution at high temperature. Field emission scanning electron micrographs confirmed the presence of a spherical shape of GNS with a diameter range of 40–80 nm. A stable and uniform PBA-modified GNS (GNS-PBA) was obtained with a facile ultrasonication step. Thus allowing aminated DNA probes of genetically modified (GM) soybean to be attached to the nanomaterials to form the DNA biosensor. The GNS-PBA/SPE exhibited excellent electrical conductivity via cyclic voltammetry (CV) and differential pulse voltammetry (DPV) tests using potassium ferricyanide (K3[Fe(CN)6]) as the electroactive probe. By employing an anthraquinone monosulfonic acid (AQMS) redox intercalator as the DNA hybridization indicator, the biosensor response was evaluated using the DPV electrochemical method. A good linear relationship between AQMS oxidation peak current and target DNA concentrations from 1.0 × 10−16to 1.0 × 10−8M with a limit of detection (LOD) of less than 1.0 × 10−16M was obtained. Selectivity experiments revealed that the voltammetric GM DNA biosensor could discriminate complementary sequences of GM soybean from non-complementary sequences and hence good recoveries were obtained for real GM soybean sample analysis. The main advantage of using GNS is an improvement of the DNA biosensor analytical performance.
Disentangling dark and luminous phases of nanosecond discharges developing in liquid water

Published: August 2020

Abstract
There is no clear experimental evidence of the underlying microscopic physical mechanisms of micro-discharges directly produced in liquids. In this study, we examine shadowgraph images and plasma-induced emission (PIE) to decouple simultaneously developing dark and luminous phases of micro-discharges with nanosecond durations in liquid water. We apply diagnostics with extremely high temporal (down to 30 ps) and spatial (down to 1 μm) resolutions to capture tiny bush-like dark filaments that expand from the anode tip together with the formation of luminous tree-like structures. For the first time, we disentangle two closely coupled dark and luminous phases of the discharge events and determine their onsets accurately with respect to the driving high-voltage (HV) pulse. The dark filaments start appearing within ∼3–4 ns after the onset of the HV pulse, and subsequently expand at a constant velocity of ∼1 × 105–2 × 105 m s−1, depending on the HV amplitude and anode curvature. A systematic analysis of the PIE waveforms using the associated shadowgraph images reveals that the onset of the luminous discharge phase is delayed by ∼600–800 ps with respect to the onset of the initial dark filament structures. Considering the constant propagation velocity of dark filaments, the luminous phase starts to develop when the extension of regions with a perturbed refractive index (i.e., perturbed density) reaches several tens of micrometres. An analysis of PIE tracks within the captured shadowgraph images confirms that luminous filaments develop only in regions affected by primary dark filaments and their attachment to the anode surface coincides with points of initial onset of the first dark filaments. Furthermore, the emission intensity produced during the luminous phase originates from the luminous filaments developing in the bulk liquid. Our study provides an important insight into the dynamics of different phases of micro-discharges in de-ionised water.
On uniformity and non-local transport in low pressure capacitively coupled plasmas
Authors: Rauf Shahid 
Published: August 2020

Abstract
Low pressure (<30 mTorr) capacitively coupled plasmas (CCP) are important for many plasma processing applications. Due to high energy of electrons in these plasmas and long electron mean free path, kinetic phenomena dominate the electron behavior. A multi-dimensional particle-in-cell (PIC) model is utilized to study the physics of sub-100 mTorr Ar CCPs in this article. A one-dimensional model for helium plasma in the 30–300 mTorr pressure range is first used to benchmark the PIC code against published results by Turner et al [2013 Phys. Plasmas 013507]. The article then focuses on two-dimensional modeling of the gaseous electronics conference (GEC) reference cell in cylindrical geometry. Computed ion density and DC bias voltage at 100 mTorr are compared to available experimental data for a range of radio frequency voltages, demonstrating good agreement. The validated model is used to examine Ar plasmas in the GEC reference cell in the 12.5–100 mTorr pressure range. It is found that the peak in ion and electron densities is near the electrode edge at 100 mTorr due to strong electric field there. As the gas pressure decreases, the peak in plasma density moves to the chamber center. This change in plasma spatial profile is linked to kinetic behavior of electrons, both regarding plasma production and transport in the plasma. Time-dependent results are used to illustrate that electron current at 25 mTorr is mainly kinetic and carried by beam electrons generated by expanding sheaths.

Published: August 2020

Abstract
Farmer’s exchange rate (FER) is a proxy indicator to value the farmer’s purchasing rate and shows the term of trade between agricultural products and services sold and the goods purchased by farmers in producing and consuming households. FER obtained by comparing the Farmer Received Price Index with the Farmer Paid Price Index both expressed as percentages. The purpose of this study is to predict the FER of Bali Province from May 2019 to December 2019 and to count the level of purchasing power of the farmers. The monthly data of FER from January 2010 to April 2019 were used to build a seasonal ARIMA (SARIMA). Four models i.e. SARIMA(0, 1, 3), SARIMA(3,1, 0), SARIMA(4,1,0), and SARIMA(1,1, 1) with seasonal factor (0,1, 1)12 were tested. Referring AIC value for SARIMA(0,1,3) as much as 326.94 is the lowest then we inferred this model is the best SARIMA model to predict the FER of Bali Province. Our research concludes the farmer’s income increases more than their expenditures.

Published: August 2020

Abstract
In this paper, we consider a mathematical model for the study of the interaction between leukemia cells and chemotherapeutic drug in Acute Myeloid Leukemia (AML). In our model, there are three compartments, namely, leukemia-initiating cells, leukemics blast, and chemotherapeutic drug. Using a stability theory of differential equation, we analyze the existence and stability of the system at various equilibrium points. Furthermore, we discuss the effect of leukemia treatment by varying the values of relevant parameters. We also provide numerical simulations to illustrate the theoretical results.
