Resumo
Objetivos A falha do componente glenoidal é a principal causa de revisão da artroplastia total do ombro (ATO) e sua frequência parece ser influenciada pelo design do componente. O objetivo deste estudo foi a avaliação clínica e radiográfica (através de raios X e tomografia computadorizada) dos resultados da ATO com componente glenoidal minimamente cimentado.
Métodos O presente trabalho analisou ATOs realizadas com componente glenoidal Anchor Peg (DuPuy Synthes, Warsaw, IN, EUA) minimamente cimentado entre 2008 e 2013. Por um período mínimo de acompanhamento de 24 meses, escores segundo critérios da University of California at Los Angeles (UCLA) e imagens padronizadas de radiografia simples e tomografia computadorizada foram analisadas. A presença de osso entre as aletas do pino do componente central, que é um indicador de sua integração, foi avaliada nas imagens, bem como a presença de linhas radiotransparentes ao redor do componente glenoidal.
Resultados Dezenove ombros de 17 pacientes foram avaliados. De acordo com o escore da UCLA, os resultados clínicos foram satisfatórios em 74% dos casos e moderados em 21% dos casos. O resultado foi ruim em um paciente. A integração de componentes foi observada em 58% dos pacientes, sendo total em 42% e parcial em 16% dos casos. Linhas radiotransparentes foram observadas em 52% dos pacientes. Nenhuma relação entre a integração de componentes e os resultados clínicos foi detectada.
Conclusão A maioria dos pacientes submetidos à ATO com componente glenoidal minimamente cimentado apresentou resultados clínicos satisfatórios. Linhas radiotransparentes ao redor do componente glenoidal são comuns, mas não interferem nos resultados clínicos

Significance
Methods for analyzing individual-level geo-located disease data have existed for some time, but have rarely been used to analyze endemic human diseases. Here we apply such methods to nearly a decade’s worth of uniquely detailed epidemiological data on incidence of the deadly vector-borne disease visceral leishmaniasis (VL) and its secondary condition, post–kala-azar dermal leishmaniasis (PKDL), to quantify the spread of infection around cases in space and time by inferring who infected whom, and estimate the relative contribution of different infection states to transmission. Our findings highlight the key role long diagnosis delays and PKDL play in maintaining VL transmission. This detailed characterization of the spatiotemporal transmission of VL will help inform targeting of interventions around VL and PKDL cases.

Significance
Memory CD8 T lymphocytes are a long-lived population of immune cells that provide formidable protection against infections and malignancy and are thus often central to vaccine and cancer immunotherapy efficacy. Here we refine the identity, developmental relationships, and functional roles of memory CD8 T cells in mice through delineation of a discrete population that confers robust protection against reinfection and exhibits an unexpected molecular program bearing typically divergent characteristics of short-lived effector cells and long-lived memory T cells. Mass cytometry and single-cell RNA-sequencing analyses revealed an analogous population of cells in humans. These findings hold broad implications for both informing immunotherapy treatments and predicting their efficacy.

Significance
We present an individual-level model of severe acute respiratory syndrome coronavirus 2 transmission that accounts for population-specific factors such as age distributions, comorbidities, household structures, and contact patterns. The model reveals substantial variation across Hubei, Lombardy, and New York City in the dynamics and progression of the epidemic, including the consequences of transmission by particular age groups. Across locations, though, policies combining “salutary sheltering” by part of a particular age group with physical distancing by the rest of the population can mitigate the number of infections and subsequent deaths.
Constrained optimal foraging by marine bacterioplankton on particulate organic matter

Published: September 2020

Significance
Patch use theory predicts that organisms foraging in a heterogeneous resource landscape balance their residence time on a patch yielding diminishing returns with the sum of the metabolic, predation, and opportunity costs of foraging. By combining single-cell tracking with mathematical modeling, we show that bacteria foraging on seascapes of organic particles switch between attached and planktonic lifestyles and tune the time spent on particles to increase individual fitness. As predicted by patch use theory, bacteria remain longer on particles of higher quality and in poor environments, or when search times for fresh particles are longer. These results show that patch use theory can be a valuable framework to understand not only animals, but also microorganisms, and ultimately their ecosystem-level consequences.
Non-aligned Einstein–Maxwell Robinson–Trautman fields of Petrov type D
Authors: Van den Bergh Norbert , Carminati John 
Published: September 2020

Abstract
We discuss Petrov type D Einstein–Maxwell (EM) fields in which both double null eigenvectors of the Weyl tensor are non-aligned with the eigenvectors of a non-null electromagnetic field and are assumed to be geodesic, shear-free, diverging and non-twisting. We obtain the general solution of the EM equations under the extra condition that the complex null vectors of the Weyl canonical tetrad are hypersurface orthogonal. The corresponding space–times are all conformally related to a Killing–Yano space and are described by a 5-parameter family of metrics, admitting two commuting Killing vectors and having the C-metric as a possible vacuum limit.
Strong temperature-dependent thermoelectric power of IrMn3 thin films of different thicknesses
Authors: Hu Junfeng , Kothari Mukund Krishna , Eimer Sylvain , Zhao Weisheng , Yu Haiming , Ansermet Jean-Philippe 
Published: September 2020

Abstract
IrMn3 thin films were experimentally characterized by thermoelectric power and resistivity as a function of temperature and sample thickness. The Seebeck coefficient shows strong temperature dependence and the value increases with temperature up to 350 K. An empirical Boltzmann sigmoid function can fit our data remarkably well. The temperature-dependent resistivity shows a similar behavior as the thermoelectric power, i.e. both these two properties exhibit a transitional behavior at some critical temperature range, which is further confirmed by the magnetic susceptibility measurements.
Violation of Stokes–Einstein and Stokes–Einstein–Debye relations in polymers at the gas-supercooled liquid coexistence
Authors: Singh Jalim , Jose Prasanth P 
Published: September 2020

Abstract
Molecular dynamics simulations are performed on a system of model linear polymers to look at the violations of Stokes–Einstein (SE) and Stokes–Einstein–Debye (SED) relations near the mode coupling theory transition temperature T
c at three (one higher and two lower) densities. At low temperatures, both lower density systems show stable gas-supercooled-liquid coexistence whereas the higher density system is homogeneous. We show that monomer density relaxation exhibits SE violation for all three densities, whereas molecular density relaxation shows a weak violation of the SE relation near T
c in both lower density systems. This study identifies disparity in monomer mobility and observation of jumplike motion in the typical monomer trajectories resulting in the SE violations. In addition to the SE violation, a weak SED violation is observed in the gas-supercooled-liquid coexisting domains of the lower densities. Both lower density systems also show a decoupling of translational and rotational dynamics in this polymer system.

Published: September 2020

Abstract
In this research, we have investigated the unintended graphene nucleation problem and its damaging effects on monolayer graphene synthesis in low-pressure chemical vapor deposition (LPCVD) process. This problem is the growth of graphene on the copper surface with no carbon feedstock. A new source of undesired carbon species was identified which has not been addressed so far. The hydrogen-rich heating stage was diagnosed as the onset of the unintended nucleation for the first time owing to the determinant catalytic role of hydrogen in this stage. It was found out that this problem leads to uncontrollable growth of multilayer graphene, growth of defective graphene film and also inhibition of the reliable synthesis of monolayer graphene. We managed to grow enhanced-quality monolayer graphene by developing some innovative solutions to the problem containing a general solution based on the hydrogen effects in the heating stage. The results reveal a significant decrease in the unintended nucleation density from ∼2000 to almost zero domains per 100 × 100 μm2 copper area. Furthermore, Raman, HRTEM and SAED analysis confirm the defect-free growth of monolayer graphene after employing the solutions. These findings could pave the way for the reliable synthesis of high-quality monolayer graphene as well as large-sized graphene domains.
Current propagation behaviors and spin filtering effects in three-terminal topological-insulator junctions
Authors: Yang Jia-En , Lü Xiao-Long , Xie Hang 
Published: September 2020

Abstract
Understand the spin and current behavior in the topological-insulator (TI) system is crucial for the design of electronic and spintronic devices. To study these behaviors, some three-terminal hetero-junction TI systems made from the zigzag silicene-like nanoribbons (ZSiNRs) are investigated. Different external fields are applied in the leads and conductor regions, which result in the expected topological edge states. By calculating the local current distribution, we find two important characteristics of topological edge current propagating in these systems. Firstly, the topological edge current prefers to flow into the nearest channel, rather than the other faraway channels. Secondly, the group-velocity mismatch as a scattering engineering has a significant effect on current propagation behavior. In other words, one can manipulate the topological edge current by velocity mismatch. Based on these characteristics, a type of three-terminal spin filter is proposed in this paper. Moreover, some interesting transport phenomena such as space-separated Fano-resonance are also discovered in the TI-junction systems.
From the open generalized Heisenberg model to the Landau–Lifshitz equation
Authors: Norambuena Ariel , Franco Andrés , Coto Raúl 
Published: September 2020

Abstract
Magnetic systems can be described by the classical Landau–Lifshitz (LL) equation or the fully quantum open generalized Heisenberg model. Using the Lindblad master equation and the mean-field approximation, we demonstrate that the open generalized Heisenberg model is reduced to a generalized LL equation. The open dynamic is modeled using spin-boson interactions with a common bosonic reservoir at thermal equilibrium. By tracing out the bosonic degrees of freedom, we obtain two different decoherence mechanisms: on-site dissipation and an effective spin–spin interaction mediated by bosons. Using our approach, we perform hysteresis calculations, closely connected with the Stoner–Wohlfarth theory. We compare the exact numerical master equation and the mean-field model, revealing the role of correlations originated by non-local interactions. Our work opens new horizons for the study of the LL dynamics from an open quantum formalism.

Abstract
Integrated edge-localized-mode (ELM)-free or small ELM scenarios for the demonstration fusion power plant (DEMO) are investigated in ASDEX Upgrade using argon seeding for radiative power removal mainly in the pedestal region. An important aspect is the modification of the electron pressure in the pedestal by the additional radiative power losses. Full ELM suppression could be achieved in a no-ELM H-mode scenario featuring an edge electromagnetic quasicoherent mode up to a heating power of 5 MW, where argon radiation allowed the extension of the heating power operational space. At higher powers up to 12 MW (reaching the beta limit), ELMs of reduced size prevail and detachment is obtained by the argon seeding. Control of the position of a radiating zone localized inside the X-point was found to be favorable compared to the control of the separatrix power for low

. Integration of pedestal cooling with Ar and ELM suppression by resonant magnetic perturbations (RMP) allowed an increase of the core radiation and a partial recovery of normalized confinement to H98 = 1. This favorable behavior is finally limited by the loss of the RMP density pump-out effect, followed by an ELM-free H-mode phase and re-occurrence of ELMs. For an active tailoring of the pedestal pressure profile, precise knowledge of the radiation profile is required. Modeling of the argon radiation profile with the STRAHL code showed good agreement with bolometry only if charge exchange of neutral deuterium with argon ions was taken into account, highlighting the importance of the neutral density in the pedestal region. In view of best integration of a no-ELM scenario with divertor detachment and high heating power, the divertor compression and enrichment of argon and neon were compared using dynamic gas puff experiments. Argon shows more than a factor of 3 higher divertor enrichment compared to neon, but the absolute values decrease with higher neutral deuterium pressure.

Abstract
The International Fusion Materials Irradiation Facility (IFMIF) is a projected accelerator-based, D-Li neutron source for fusion reactor materials qualification. LIPAc (Linear IFMIF Prototype Accelerator) is an accelerator aiming to generate a 125 mA, 9 MeV continuous wave deuteron beam, which is currently being commissioned in Rokkasho (Japan) with the objective of validating the IFMIF accelerator design.
In LIPAc, a 10 m long High Energy Beam Transport line (HEBT) will connect the exit of the superconducting linac to the beam dump (BD). The HEBT line must accommodate the diagnostics for beam characterization and open the beam at the end to allow its stopping at the BD. The line contains several magnets to control the beam shape and its trajectory, maintaining beam losses below 1 W m−1 along the beamline to limit activation of surrounding elements and allow hands-on maintenance.
In this work, the LIPAc HEBT line project is described since its origins. A summary of the beam dynamics calculations and other studies (vacuum, radioprotection, assembly, alignment) that led to the conceptual design of the line is done. After that, the detailed design of the line is presented, justifying the main design decisions taken and finally, the manufacturing and procurement process and the acceptance tests performed are summarized.
Numerical viscosity in simulations of the two-dimensional Kelvin-Helmholtz instability
Authors: Obergaulinger M. , Aloy M.Á. 
Published: September 2020

Abstract
The Kelvin-Helmholtz instability serves as a simple, well-defined setup for assessing the accuracy of different numerical methods for solving the equations of hydrodynamics. We use it to extend our previous analysis of the convergence and the numerical dissipation in models of the propagation of waves and in the tearing-mode instability in magnetohydrodynamic models. To this end, we perform two-dimensional simulations with and without explicit physical viscosity at different resolutions. A comparison of the growth of the modes excited by our initial perturbations allows us to estimate the effective numerical viscosity of two spatial reconstruction schemes (fifth-order monotonicity preserving and second-order piecewise linear schemes).
On Entropy Conservation and Kinetic Energy Preservation Methods
Authors: Yee H. C. , Sjögreen Björn 
Published: September 2020

Abstract
The Tadmor-type entropy conservative method using the mathematical logarithmic entropy function and two forms of the Sjogreen & Yee entropy conservative methods using the Harten entropy function are examined for their nonlinear stability and accuracy in very long time integration of the Euler equations of compressible gas dynamics. Following the same procedure as Ranocha [6] these entropy conservative methods can be made kinetic energy preserving with minimum added computational effort. The focus of this work is to examine the nonlinear stability and accuracy of these newly introduced high order entropy conserving and kinetic energy preserving methods for very long time integration of selected test cases when compared with their original methods. Computed entropy, and kinetic energy errors for these methods are compared with the Ducros et al. and the Kennedy-Gruber-Pirozzoli skew-symmetric splittings.

Abstract
The giant clams (Tridacnidae) found in tropical coral reef ecosystems of the Indo-Pacific are considered endangered, with declining populations throughout most of their range. One anthropogenic impact which could have adverse effects on giant clam populations is hydrocarbon pollution. We conducted an acute toxicity test to assess the effect of the water-accommodated fraction (WAF) of diesel on the mortality, morphology, and behavior of fluted giant clam (Tridacna squamosa) veliger phase larvae. The D-veliger larvae (ten per experimental unit) were exposed to different concentrations of diesel (control, 0.1, 1, 2.5, 5, and10 ml L−1) using a 24-hr static nonrenewal test with four replicates per treatment. The 24-hr LC50 of diesel was 1.14 ml L−1 (CI: 0.65- 1.98 ml L−1) based on Finney’s Probit Method. There were no morphological abnormalities (shell deformation) detected at the concentrations tested. However, the expulsion of zooxanthellae was observed at the higher concentrations (2.5, 5, and 10 ml L−1), and the severity of this phenomenon increased in line with diesel concentration. The decreased density of zooxanthellae detected in some living veliger larvae could weaken the larvae and lead to increased mortality.

Published: September 2020

Abstract
The geological conditions in Southwest China are complex, and the dangerous rock hazards developed in the high and steep slopes has extremely high harmfulness and concealment. The traditional contact survey method is difficult to find out the geological hazard effectively under the limitation of complex and changeable terrain conditions. Unmanned aerial vehicle photogrammetric system has high flexibility and can obtain high-efficient, high precision and high resolution remote sensing images of geological disaster investigation area. By using the UAV photogrammetry system, the dangerous rock mass of the intake slope of Jinping secondary hydropower station is investigated. The working principle of UAV, the acquisition of high-definition image data and the construction of 3D model are discussed, and the feasibility of using the model data obtained by the system to investigate dangerous rock mass is demonstrated. Through repeated analysis and interpretation of the 3D real-scene model, the distribution characteristics of the dangerous rock hazard points of the intake slope are found out. On this basis, four sections are selected to simulate the movement track of unstable dangerous rock mass with Rocfall software, and the movement velocity, jump height and impact energy of different characteristic points of falling rock are calculated quantitatively with the formula.The research results provide an important reference value for the investigation of dangerous rock mass of high and steep slope in southwest China.

AbstractSatellite remote sensing data has the advantages of wide coverage, short imaging cycle, and nocturnal imaging. It has important applications in earthquake disaster monitoring. The built up remote sensing satellite receiving station of our lab could collect the MODIS, NOAA, FY3 Series data. In this paper, we developed a geometric correction algorithm based on conjugate triangles and affine transformation for remote sensing satellite data in the first, and then produce land surface temperature (LST), Vegetation Index (NDVI), and aerosol products for seismic disaster monitoring. In the future work, the products will be applied for earthquake disaster monitoring.
