Aldosteronism
Authors: Meyer Lucie S. , Gong Siyuan , Reincke Martin , Williams Tracy Ann 
Published: March 2020

AbstractPrimary aldosteronism (PA) is the most common form of endocrine hypertension.
Agonistic autoantibodies against the angiotensin II type 1 receptor
(AT1R-Abs) have been described in transplantation medicine and
women with pre-eclampsia and more recently in patients with PA. Any functional
role of AT1R-Abs in either of the two main subtypes of PA
(aldosterone-producing adenoma or bilateral adrenal hyperplasia) requires
clarification. In this review, we discuss the studies performed to date on
AT1R-Abs in PA.

Published: March 2020

ABSTRACTPulp stones are usually found in the pulp chamber. Radiographically, they appear as radiopaque structures in the pulp chambers or root canals of individual teeth. Generalized pulp stones throughout the dentition are usually associated with systemic or genetic disorders of the dentine. This report presents an unusual case of a 13-year-old girl with generalized pulp stones with clinically normal crowns. The patient’s main complaint was a crossbite affecting all permanent canines. Radiographic examination revealed multiple pulp stones and several teeth with atypically shaped roots. Orthodontic treatment, gingivoplasty, and esthetic restorations were performed, thus using a multidisciplinary approach to establish functionally and esthetically sound dentition.

Authors: Al-Thobity Ahmad M. 
Published: March 2020

Abstract
Objective Different polymerization and reinforcement techniques have been tested to enhance the mechanical characteristics of denture base acrylic resins. The goal of the present study was to evaluate the influence of autoclave polymerization techniques with glass fiber reinforcement on the flexural strength and elastic modulus of polymethyl methacrylate denture base resins.
Materials and Methods Ninety specimens were fabricated from heat-polymerized acrylic resin and randomly distributed depending on the polymerization technique into three groups (n = 30): water bath polymerization, short-cycle autoclave polymerization, and long-cycle autoclave polymerization. Each group was further divided into three subgroups (n = 10) based on the concentration of glass fiber 0, 2.5, and 5wt%. The flexural strength and elastic modulus were investigated using a universal testing machine. One-way ANOVA and Tukey’s post hoc test were performed to analyze the results (α = 0.05).
Results The flexural strength and elastic modulus values were significantly higher in 5wt% glass fiber reinforced long-cycle autoclave group in comparison with the other test groups (p < 0.05).
Conclusions The long-cycle autoclave polymerization technique with the glass fiber reinforcement significantly increased the flexural strength and elastic modulus of the denture base resin material.

Published: March 2020

Abstract
Objective The aim of study was to evaluate in vitro the surface hardness, sorption, solubility, and color stability of three light-cured resin cements, namely RelyX Veneer (RLX), Variolink Veneer (VLK), and All Cem Veneer (ACV).
Materials and Methods Cylindrical samples (15 × 1 mm) were made for each group using a metallic mold (n = 10). Vickers microhardness test was performed, and average hardness was calculated from three indentations (300 gf/15s) per sample. The sorption and solubility of the materials were evaluated according to ISO 4049:2009 based on three samples weighing: initial (m
1), after immersion in distilled water for 7 days (m
2), and final (after removal of all moisture [m
3]). The color change was observed using a digital spectrophotometer, at three different time points, baseline, 1 day, and 1 week of immersion in coffee and distilled water (control).
Statistical Analysis Shapiro–Wilk test was used to analyze the normality of the data, and groups were compared using Kruskal–Wallis and Mann–Whitney tests. A significance level of 5% was used.
Results RLX showed the highest microhardness mean values (36.96 VHN), but higher sorption (23.2 µg/mm3) and solubility (2.40 µg/mm3), with statistically significant differences with the other groups. For color stability, higher ∆E was observed for the samples immersed in coffee (p = 0.009). The VLK resin cement presented statistically significant differences from the other groups, with higher color changes in coffee at 1 day (15.14) and after 1 week (23.65).
Conclusion RLX resin cement showed better hardness results. All materials tested performed satisfactorily for sorption and solubility according to ISO 4049:2009. All materials showed high-staining values after 1 week of immersion in coffee.

Abstract
We have theoretically investigated Brillouin lasing in microcavities in the case when the Brillouin shift and the intermode spacing of the microcavity do not coincide. It is shown that, despite the rise of the lasing threshold, a significant increase in the Brillouin signal intensity can be achieved in this case compared to the resonance one. A necessary condition for this effect is to select an optimal value of detuning of the pump radiation frequency from the frequency of the corresponding microcavity mode. The result of increasing the lasing threshold is also a narrowing of the Brillouin signal lasing range in the nonresonant case, which leads to a decrease in the signal noise level provided the detuning value is optimally selected. Analytical calculations are confirmed by the results of numerical modelling.
Femtosecond dynamics of cavity modes in ZnSe films on a metal
Authors: Vinogradov E.A. 
Published: March 2020

Abstract
The ultrafast evolution of cavity modes in a ZnSe film on a metal (Cr, Cu, or Ni) is studied by femtosecond pump/supercontinuum-probe spectroscopy on a time scale of several tens of femtoseconds. Femtosecond excitation of a microcavity in a ZnSe film on a metal substrate leads to a change in the parameters of cavity (Fabry – Perot) modes. The cavity-mode frequency shifts are due to the photoinduced changes in the boundary conditions and the optical thickness of microcavity.

Abstract
Coherent dynamics of lattice oscillations in a ∼20-nm-thick film obtained by thermal sputtering of bismuth is studied using ultrashort electron bunches synchronised with femtosecond laser pulses irradiating the sample. The Fourier analysis of ultrafast electron diffraction (UED) data shows that the observed modulation of the signal is due to the ensemble of modes corresponding to optical phonons with frequencies of approximately 3, 6 and 9 THz. A conclusion is made that these peaks correspond to the manifestation of the bismuth A
1g mode (three-terahertz peak), as well as its first and second overtones, which is probably due to quantum confinement in a 20-nm Bi nanostructure. The possibility of a detailed study of the quantum-size effect in bismuth with the help of a transmission UED is analysed.

Abstract
Micro four-point probes (M4PP) provide rapid and automated lithography-free transport properties of planar surfaces including two-dimensional materials. We perform sheet conductance wafer maps of graphene directly grown on a 100 mm diameter SiC wafer using a multiplexed seven-point probe with minor additional measurement time compared to a four-point probe. Comparing the results of three subprobes we find that compared to a single-probe result, our measurement yield increases from 72%–84% to 97%. The additional data allows for correlation analysis between adjacent subprobes, that must measure the same values in case the sample is uniform on the scale of the electrode pitch. We observe that the relative difference in measured sheet conductance between two adjacent subprobes increase in the transition between large and low conductance regions. We mapped sheet conductance of graphene as it changed over several weeks. Terahertz time-domain spectroscopy conductivity maps both before and after M4PP mapping showed no significant change due to M4PP measurement, with both methods showing the same qualitative changes over time.
Synergy effect in hybrid nanocomposites based on carbon nanotubes and graphene nanoplatelets
Authors: Gbaguidi Audrey , Namilae Sirish , Kim Daewon 
Published: March 2020

Abstract
Hybrid nanocomposites reinforced with a mixture of graphene nanoplatelets (GNPs) and carbon nanotubes (CNTs) have shown improvement in filler dispersion while providing a cost-effective alternative to CNT monofiller composites. Depending on their composition, hybrid composites can exhibit electrical performance superior to either of the constituent monofiller composites due to synergistic effects. In this work, we develop a three-dimensional tunneling-based continuum percolation model for hybrid nanocomposites filled with hardcore particles of elliptical GNPs and cylindrical CNTs. Using Monte Carlo simulations, parametric studies of the filler content, composition and morphology are carried out to analyze the conditions required for synergy in percolation onset and electrical conductivity. Our results suggest that for hybrid systems with well-dispersed fillers, the electrical performance is linked to the number of tunneling junctions per filler inside the percolated network of the nanocomposites. More importantly, hybrid composites filled with specific morphology of GNP and CNT, exhibit synergy in their electrical performance when the monofiller composites of each of those exact fillers have similar percolation onset values. The simulations results are in agreement with relevant experimental data on hybrid nanocomposites.
Acoustic versus electromagnetic field theory: scalar, vector, spinor representations and the emergence of acoustic spin
Authors: Burns Lucas , Bliokh Konstantin Y , Nori Franco , Dressel Justin 
Published: March 2020

Abstract
We construct a novel Lagrangian representation of acoustic field theory that describes the local vector properties of longitudinal (curl-free) acoustic fields. In particular, this approach accounts for the recently-discovered nonzero spin angular momentum density in inhomogeneous sound fields in fluids or gases. The traditional acoustic Lagrangian representation with a scalar potential is unable to describe such vector properties of acoustic fields adequately, which are however observable via local radiation forces and torques on small probe particles. By introducing a displacement vector potential analogous to the electromagnetic vector potential, we derive the appropriate canonical momentum and spin densities as conserved Noether currents. The results are consistent with recent theoretical analyses and experiments. Furthermore, by an analogy with dual-symmetric electromagnetic field theory that combines electric- and magnetic-potential representations, we put forward an acoustic spinor representation combining the scalar and vector representations. This approach also includes naturally coupling to sources. The strong analogies between electromagnetism and acoustics suggest further productive inquiry, particularly regarding the nature of the apparent spacetime symmetries inherent to acoustic fields.
Temperature monitoring in mountain regions using reanalyses: lessons from the Alps
Authors: Scherrer Simon C 
Published: March 2020

Abstract
The monitoring of near-surface temperature is a fundamental task of climatology that remains especially challenging in mountain regions. Here we assess the regional monitoring capabilities of modern reanalysis products in the well-monitored northern Swiss Alps during the last 20–60 years. Monthly and seasonal 2 m air temperature (T2m) anomalies the global ERA5 and the three regional reanalysis products HARMONIE, MESCAN-SURFEX and COSMO-REA6 are evaluated against high quality in situ observational data for a low elevation (foothills) mean, and a high elevation (Alpine) mean. All reanalysis products show a good year-round performance for the foothills with the global reanalysis ERA5 showing the best overall performance. The high-resolution regional reanalysis COSMO-REA6 clearly performs best for the Alpine mean, especially in winter. Most reanalysis data sets show deficiencies at high elevations in winter and considerably overestimate recent T2m trends in winter. This stresses the fact that even in the most recent decades utmost care is required when using reanalysis data for near-surface temperature trend assessments in mountain regions. Our results indicate that a high-resolution model topography is an important prerequisite for an adequate monitoring of winter T2m using reanalysis data at high elevations in the Alps. Assimilating T2m remains challenging in highly complex terrain. The remaining shortcomings of modern reanalyses also highlight the continued need for a reliable and dense in situ observational monitoring network in mountain regions.
Uncertainty and trade-offs in quantum multiparameter estimation
Authors: Kull Ilya , Guérin Philippe Allard , Verstraete Frank 
Published: March 2020

Abstract
Uncertainty relations in quantum mechanics express bounds on our ability to simultaneously obtain knowledge about expectation values of non-commuting observables of a quantum system. They quantify trade-offs in accuracy between complementary pieces of information about the system. In quantum multiparameter estimation, such trade-offs occur for the precision achievable for different parameters characterizing a density matrix: an uncertainty relation emerges between the achievable variances of the different estimators. This is in contrast to classical multiparameter estimation, where simultaneous optimal precision is attainable in the asymptotic limit. We study trade-off relations that follow from known tight bounds in quantum multiparameter estimation. We compute trade-off curves and surfaces from Cramér–Rao type bounds which provide a compelling graphical representation of the information encoded in such bounds, and argue that bounds on simultaneously achievable precision in quantum multiparameter estimation should be regarded as measurement uncertainty relations. From the state-dependent bounds on the expected cost in parameter estimation, we derive a state-independent uncertainty relation between the parameters of a qubit system.

Published: March 2020

Abstract
Kelapa Gading is one of the sub-districts located in North Jakarta which consists of low-level plains prone to flooding. One of the areas in Kelapa Gading that is most severely affect by the floods is in front of the Mall of Indonesia (MOI). Based on earlier research, it has been reported that one of the causes of flooding in Kelapa Gading is its drainage system’s inability to pass the flood discharge. Therefore, this study discusses the micro-scale drainage system in the MOI catchment area. The purpose of this study is to evaluate the performance of the micro-scale drainage system in the Mall of Indonesia (MOI) area by comparing the results of the calculation of the flood discharge of the planned catchment area with the capacity of the drainage channels using the help of WinTR-20 and HEC-RAS applications. From the simulation results using the two applications, it can be seen that all micro drainage channels in the MOI catchment area are able to pass flood discharge up to period of 25 years, except in reach 6. Based on this, an open drainage system analysis is carried out into a polder system by placing two pumps with a capacity of 0.25 m3/s. With this proposed polder system design, the flooding in the MOI catchment area can contain the discharge up to a 25-year return period floodings.

Published: March 2020

Abstract
Damage index is a define scale to describe damage of the structure due to earthquake. Several studies of damage index have been carried out on reinforced structures, but not many studies performed on steel structures. Numerical research about damage index on moment resisting frame of steel structure has been conducted. Monotonic and semi-cyclic pushover analyses using OpenSEES software was carried out to obtain the index. Two paramaters that affect the damage index value are the displacement ratio and energy absorbsion. Damage index value of MRF obtained in this research is governed by the displacement ratio. The main objective of this study is to correlate damage index and the natural frequency. SAP2000 is used to get the natural frequency through modal analysis. The results show that natural frequency can be used to assess structural damage. Hence, structural health monitoring can be simplied by assesing the natural frequency.

Abstract
Lots of bridge failure phenomenon caused by scour on pier foundation or abutment. One of the most important factors of the bridge is the abutment. Abutment is a structure, built at the edge of the bridge. Abutment is designed to hold the weight of the bridge and over the bridge. The structure of abutment usually planted in to the river. One of methods to minimize the scour impact is considering the shape and design of abutment. This research aims to find out the effect of abutment model or shape variation (semi-circular end abutment, wing wall abutment and spill through abutment) toward the change of velocity using Flow-3D for numerical modeling, the physical test to validation the flow condition and analyze the characteristic sediment transport pattern using Hjulstörm curve. The result of research state that the spill through abutment is the most effective model to keep the stability of flow velocity around the abutment. Correlation between Froude Number (Fr) with Relative Longitudinal Distance Ratio is discussed in this paper. Then, Hjulstörm curve shows that with bed material diameter (d

Authors: Suangga Made , Furkon Muhammad Chairul 
Published: March 2020

Abstract
Shearwall plays an important role in resisting shear force generated from earthquake loads. The lay out of the shear wall is very influential on the performance of the shear wall in receiving lateral forces. To investigate how the shear wall layout affecting the performance of the structure to lateral load, pushover analysis on 27 storey structure with three different shear wall shape is conducted. The three shapes of shear wall layout considered are shear wall with C shape layout, shear wall with I shape lay-out and shear wall with L shape lay-out. The shear capacities of the structure with different shear wall shapes were checked against the design requirement in SNI 1726-2012. ETABS software were used for push over analysis. Their ductility and structural performance level based on the ATC-40 method were compared for both in x direction and y direction. From the results of the pushover over analysis it was found that shear wall with C shape layout is the most favorable since it has the highest structural stiffness and smaller drift.
