Authors: Bensinger Andrew , Wilson Farra , Green Patrick , Bloomfeld Richard , Dharod Ajay 
Published: December 2019

Abstract
Background Inflammatory bowel disease (IBD) is a chronic condition with wide variation in treatment and resource utilization because of many different disease presentations and treatment options. In an effort to standardize care and improve health outcomes, several organizations have created performance measures to monitor various aspects of IBD care.
Objectives We aimed to assess longitudinal documentation adherence with physician quality reporting system's (PQRS) IBD performance measures before, immediately after, and 1 year following the implementation of a comprehensive electronic health record (EHR) IBD clinical documentation support tool intervention.
Methods We reviewed 50 patient charts that were randomly selected from consecutive outpatient IBD visits at our tertiary care center from September 1, 2015 to June 30, 2016, prior to implementation of an IBD-specific note template, order set, and patient education handout on September 1, 2016. Two additional cohorts of 50 patient charts were randomly selected from September 1, 2016 to June 30, 2017 and September 1, 2017 to June 30, 2018. These charts were reviewed to assess adherence of pertinent PQRS performance measures for outpatient IBD care. The project was deemed not human subjects research and received exempt approval by the Institutional Review Board (IRB#: IRB00040399).
Results The cohort immediately after the intervention showed significant increases in documentation rates of influenza immunization (19–59%, p < 0.001), pneumococcal immunizations (2–38%, p < 0.001), tobacco cessation (28.6–77.8%, p = 0.049), and proportion of all eligible measures (40.6–62.2%, p < 0.001) when compared with the preintervention group. Moreover, documentation rates were sustained in the 1-year follow-up group when compared with the postintervention group.
Conclusion A multifaceted, EHR focused approach can significantly and sustainably improve documentation of outpatient IBD quality measures.
Nonlinear diffusion and hyperuniformity from Poisson representation in systems with interaction mediated dynamics
Authors: Bertrand Thibault , Chatenay Didier , Voituriez Raphaël 
Published: December 2019

Abstract
We introduce a minimal model of interacting particles relying on conservation of the number of particles and interactions respecting conservation of the center of mass. The dynamics in our model is directly amenable to simple pairwise interactions between particles leading to particle displacements, ensues from this what we call interaction mediated dynamics. Inspired by binary reaction kinetics-like rules, we model systems of interacting agents activated upon pairwise contact. Using Poisson representations, our model is amenable to an exact nonlinear stochastic differential equation. We derive analytically its hydrodynamic limit, which turns out to be a nonlinear diffusion equation of porous medium type valid even far from steady state. We obtain exact self-similar solutions with subdiffusive scaling and compact support. The nonequilibrium steady state of our model in the dense phase displays hyperuniformity which we are able to predict from our analytical approach. We reinterpret hyperuniformity as stemming from correlations in particles displacements induced by the conservation of center of mass. Although quite simplistic, this model could in principle be realized experimentally at different scales by active particles systems.
Topological spinor vortex matter on spherical surface induced by non-Abelian spin-orbital-angular-momentum coupling
Authors: Cheng Jia-Ming , Gong Ming , Guo Guang-Can , Zhou Zheng-Wei , Zhou Xiang-Fa 
Published: December 2019

Abstract
We propose a scheme to implement non-Abelian spin-orbital-angular-momentum (SOAM) coupling in spinor Bose–Einstein condensates using magnetic gradient coupling. For a spherical surface trap addressable using high-order Hermite–Gaussian beams, we show that this system supports various degenerate ground states carrying different total angular momenta J, and the degeneracy can be tuned by changing the strength of SOAM coupling. For spinor condensates with hyperfine spin F = 1, the system supports various meta-ferromagnetic phases and meta-polar states always described by quantized total mean angular momentum

The system can be used to prepare various stable spin vortex states with nontrivial topology, and serve as a platform to investigate strong-correlated physics of neutral atoms with tunable ground-state degeneracy.
The Newton problem solution of the transformed complex curve parameters
Authors: Lozhkin Alexander , Korobeynikov Alexander , Khaziyakhmetov Ruslan 
Published: December 2019

Abstract
Many tasks from the natural and engineering sciences require precision solutions with complex curves. The main obstacle is the lack of the necessary mathematical apparatus. The analysis of symmetries on the Euclidean plane by Dieudonne and the figure by Weyl allowed us to formulate a new method for obtaining the parameters of linear transformation alternative to classical. It can be used for an ellipse, hyperbola, as well as complex flat curves. The method is analyzed for trajectories having symmetries. A theorem to obtain the parameters of the transformed curve in the general case is formulated. Theoretical calculations and the results of experimental studies using the method of geometric modeling are given. The method is very new, so it may not work for some curves. There is the possibility of obtaining it, since the research uses the simplest apparatus.

Published: December 2019

Abstract
Chemical reagents used in standard technologies are significantly inferior in effectiveness to their intended use in the purification of a biological matrix by supercritical carbon dioxide due to several reasons: retention of residual solvent in the structure of the biological matrix, the presence of pronounced cytotoxicity, problems associated with capillary effects (limited penetration of the reagent to the cleaned surface), pronounced allergenicity of chemical reagents. Laboratory studies of the influence of pressure processing from 20 to 35 MPa of a two-stage bone matrix cleaning process at a holding temperature of 308, 313 K to the 60-minute static processing time and the 240-minute dynamic processing time were carried out, including subsequent biochemical analyzes to determine residual DNA, calcium protein in the obtained samples. The addition of a cosolvent - ethanol in an amount of 5% of the main solvent of supercritical CO2 was studied. Pyrogenic testing was carried out. All samples are recognized not pyrogenic. Physical properties and surface morphology were determined using a Carl Zeiss AURIGA CrossBeam scanning electron microscope. Identification and quantification of potential degradation products using liquid chromatography was determined.

The non-capacitor model of leaky integrate-and-fire VO2 neuron with the thermal mechanism of the membrane potential
Authors: Velichko A A , Belyaev M A , Ryabokon D V , Khanin S D 
Published: December 2019

Abstract
The study presents a numerical model of leaky integrate-and-fire neuron created on the basis of VO2 switch. The analogue of the membrane potential in the model is the temperature of the switch channel, and the action potential from neighbouring neurons propagates along the substrate in the form of thermal pulses. We simulated the operation of three neurons and demonstrated that the total effect happens due to interference of thermal waves in the region of the neuron switching channel. The thermal mechanism of the threshold function operates due to the effect of electrical switching, and the magnitude (temperature) of the threshold can vary by external voltage. The neuron circuit does not contain capacitor, making it possible to produce a network with a high density of components, and has the potential for 3D integration due to the thermal mechanism of neurons interaction.

Published: December 2019

Abstract
The use of reindeer resources in Central Siberia - the main welfare source for the majority of farms and the indigenous population of the North region. Protection and rational use of Taimyr-Evenk reindeer population inhabiting the Krasnoyarsk territory on the area of more than 1.5 million km2 are impossible without the use of modern remote sensing methods. It provides objective and live data information about the spatial and temporal location of animals at different stages of their life cycle. Monitoring carried out with the use of modern technical devices allows to solve not only applied control problems, but also to obtain new unique knowledge about the biology of this species. The basis for this message was the materials on the use of collars equipped with satellite transmitters of the Argos system and worn on deer. A total number of collars was 17, which were worn on reindeer in their wintering grounds, except for one, which a half-grown female was marked during the crossing of the Heta river. From a technical point of view, it was important to trace the total duration of the beacon and the viability of the battery packs in extreme temperature amplitude and also to establish reliability of the device protection from physical and mechanical influence during migrations of animals. The maximum duration of signal receipt with using the new battery packs in 2015-2016 amounted to 438 and 444 days, in 2017-2018 – 539 days. The maximum length of the deer during the satellite direction finding was 9538 km. The average speed was 13.5 km / day; the maximum was up to 45-72 km / day in azimuth. Used collars with radio beacons of Argos satellite system produced by ES-PAS Ltd. (Russia), showed a high degree of functional reliability.
