Background Effective interventions for overdose survivors are needed in the emergency departments (EDs). One promising model is the use of peer recovery coaches to engage with survivors in EDs, followed by partnering with community case management navigators to connect survivors to recovery support and treatment services. This paper describes the evaluation of a pilot program, the Recovery Opioid Overdose Team (ROOT), a warm hand-off system that links survivors to treatment services post-ED discharge. Methods The ROOT program is composed of a peer recovery coach who is in long-term recovery, and a case management navigator who specializes in mental health care and provides guidance for accessing community services. After an overdose reversal, law enforcement contacts a county 24/7 Crisis Team, who then notifies ROOT. The peer recovery coach engages with the survivor in the ED, and then follow up continues with the case management navigator and the peer recovery coach for up to 90 days post-ED discharge. Retrospective chart reviews were conducted to evaluate ROOT in two Midwest EDs from September 2017 through March 2019. Results Of the 122 referrals, 77.0% ( n = 94) of the survivors initially engaged with ROOT in the ED or in the community. The remaining 23.0% ( n = 28) left the ED against medical advice or were unengaged. The majority of overdose survivors were male (63.9%; n = 78), White (43.4%; n = 53), had housing (80.2%; n = 48), and access to transportation (48.4%; n = 59). From the 122 referrals, 33.6% ( n = 41) received ongoing treatment services ( n = 20 outpatient, n = 17 residential, n = 2 detoxification facility, n = 1 recovery housing, n = 1 medication treatment for opioid use disorder), 2.5% ( n = 3) were incarcerated, 2.5% ( n = 3) died, and 61.5% ( n = 75) declined services. Conclusions The ROOT, a community-wide coordinated program in the EDs, shows promise in linking overdose survivors to recovery support and treatment services post-overdose.

Simulation of cell deformation inside a microfluidic channel to identify parameters for mechanical characterization of cells
Authors: Schuster Ralf , Marti Othmar 
Published: December 2020

Abstract
The mechanical characterization of different cell types is important to improve the physiological understanding of cells. Cell types can be differentiated by their elasticity, which is a measure of the amount of deformation under a given stress. Simulations based on the finite element method help us to understand, verify and improve the analysis of deformation-based cell characterization methods such as flow-based cytometry. We achieve efficient computations using a 2D-rotationally symmetric model, based on fluid-structure interaction with a hyper-elastic material. The deformation of a cell along the entirety of a microfluidic channel can be tracked for a variety of elasticities, viscosities, cell sizes, channel geometries and flow rates. The model is even able to simulate soft cells with Young’s modulus of a few hundred pascals in microfluidic channels up to 2 mm in length. Simulations can be carried out in media with constant viscosity as well as in non-Newtonian fluids with shear-dependent viscosity. We have shown that the cell carrier-medium has a strong influence on cell deformation. The position of steady-state deformation dependence on cell properties is investigated. Furthermore, the simulation model can reproduce experimentally observed relaxation of cells, which can then be mapped to actual material parameters to classify and distinguish different cell types.
Roughness evolution in strongly interacting donor:acceptor mixtures of molecular semiconductors. An in situ, real-time growth study using x-ray reflectivity

Published: December 2020

Abstract
The evolution of surface roughness in binary mixtures of the two molecular organic semiconductors (OSCs) diindenoperylene (DIP) as electron-donor and 1, 3, 4, 5, 7, 8-hexafluoro-tetracyano naphthoquinodimethane (F6TCNNQ) as electron-acceptor is studied. We co-deposit DIP and F6TCNNQ in vacuum with varying relative molar content while keeping a molar excess of DIP in order to produce phase-heterogeneous mixtures. The excess DIP phase segregates in pristine crystallites, whereas the remaining mixed phase is constituted by DIP:F6TCNNQ co-crystallites. We calculate the surface roughness as function of film thickness by modelling x-ray reflectivity data acquired in situ and in real-time during film growth. To model the experimental data, two distinct approaches, namely the kinematic approximation and the Parratt formalism, are applied. A comparative study of surface roughness evolution as function of DIP:F6TCNNQ mixing ratio is carried out implementing the Trofimov growth model within the kinematic approximation. Depending on the thickness regime, mixing ratio-specific trends are identified and discussed. To explain them, a growth mechanism for binary heterogeneous mixtures of strongly interacting OSCs is proposed.

Abstract
Electrohydrodynamic jet (E-Jet) printing is a powerful technique for micro/nanostructure fabrication with high resolution and efficiency. However, conventional E-Jet printing are still limited in printing accuracy and ink adaptability due to the nozzle clogging effect. In this paper, we develop a nano-tip focused electrohydrodynamic jet (NFEJ) method to print high-resolution structures. The Ni cantilever nanoprobes with nanoscale radius of curvature (ROC) on their tips were manufactured by a facile and scalable method using silicon template and micro-electroforming technique. Scanning electron microscope was used to analyse the micromorphology of the silicon template with inverted pyramid pits, which was obtained from anisotropic wet etching of silicon. Electroforming mold was obtained by photolithography and plasma etching which divide the top side of Ni film into isolated cantilever pits. Ni cantilever nanoprobes with an average tip ROC of about 48 nm were achieved by the subsequent micro electroforming process. High-resolution droplets array with an average diameter of about 890 ± 93 nm were printed by the NFEJ printing head equipped with these Ni nanoprobes, which verified the practicality of the developed Ni nanoprobes for NFEJ printing.

Abstract
Graphene oxide-quantum dots systems are emerging as a new class of materials that hold promise for biochemical sensing applications. In this paper, the eco-friendly carbon quantum dots (CQDs) are prepared with cheap and recyclable coke powders as carbon source. The graphene oxide-carbon quantum dots (GO-CQDs) composites are synthesized using graphene oxide as the conductive skeleton to load the CQDs by a one-step calcination method. The obtained GO-CQDs composites demonstrate the successful decoration of CQDs on GO nanosheets. The CQDs acting as spacers create gaps between GO sheets, resulting in a high surface area, which electively increases the electrolyte accessibility and electronic transmission. The electrocatalytic activity and reversibility of GO-CQDs composites can be effectively enhanced by tuning the mass ratio of GO to CQDs and the heating process. Furthermore, a highly sensitive and selective electrochemical sensor for determining uric acid (UA) and ascorbic acid (AA) was developed by modifying GO-CQDs composites onto a glassy carbon electrode. The results show that the linear range, minimum detection limit, and sensitivity of the GO-CQDs electrode for UA detection are 1–150 μM, 0.01 μM, and 2319.4 μA mM−1 cm−2, respectively, and those for AA detection are 800–9000 μM, 31.57 μM, and 53.1 μA mM−1 cm−2, respectively. The GO-CQDs are employed as the electrode materials for the serum and urine samples electrochemical sensing, the results indicate that the sensor can be used for the analysis of real biological samples.
Bethe ansatz approach for dissipation: exact solutions of quantum many-body dynamics under loss
Authors: Buča Berislav , Booker Cameron , Medenjak Marko , Jaksch Dieter 
Published: December 2020

Abstract
We develop a Bethe ansatz based approach to study dissipative systems experiencing loss. The method allows us to exactly calculate the spectra of interacting, many-body Liouvillians. We discuss how the dissipative Bethe ansatz opens the possibility of analytically calculating the dynamics of a wide range of experimentally relevant models including cold atoms subjected to one and two body losses, coupled cavity arrays with bosons escaping the cavity, and cavity quantum electrodynamics. As an example of our approach we study the relaxation properties in a boundary driven XXZ spin chain. We exactly calculate the Liouvillian gap and find different relaxation rates with a novel type of dynamical dissipative phase transition. This physically translates into the formation of a stable domain wall in the easy-axis regime despite the presence of loss. Such analytic results have previously been inaccessible for systems of this type.
Finite difference computation of free magneto-convective Powell-Eyring nanofluid flow over a permeable cylinder with variable thermal conductivity

Published: December 2020

Abstract
It is essential to account the variability in thermophysical properties such as thermal conductivity to obtain the characteristics of transport properties in industrial thermal systems more accurately. This phenomenon is especially significant in coating protection for rocket chambers, heat exchangers and power generation, wherein cooling techniques are required for sustaining temperature regulation and structural material integrity. At high operating temperatures, the working fluid and hot walls generally emit appreciable radiation. Mathematical models are therefore required which simultaneously analyse all three modes of heat transfer in addition to viscous flow and a variety of other effects including reactions (corrosion, combustion), mass diffusion and rheological behaviour. The modern thrust in nanoscale materials is a major consideration. Motivated by these applications, in this paper, a theoretical examination is implemented to analyse the impact of thermal conductivity variation and thermal radiation on chemically reacting, free convective Powell-Eyring nanofluid flow over a cylinder. The nanoscale effects are accounted by employing the Buongiorno model. The transformed governing equations are numerically solved by using Keller box method under suitable boundary conditions. The comparison results reveal that the obtained results find an excellent match with the results in the literature. The graphs and tables elucidate the impacts of various pertinent parameters on thermo-solutal transport characteristics. It is to be noted that amplifying thermal conductivity variation rises fluid velocity and temperature. Velocity of the fluid decelerates for elevating Darcy number. Magnifying the radiation corresponds to weak radiative flux and stronger thermal conduction which decrease the heat transfer whereas the mass transfer is increased. Furthermore, nanoparticle concentration decreases with greater first-order chemical reaction and Brownian motion parameter values.

Abstract
This article intends to describe the three-dimensional flow of nanofluid consisting of carbon nanotubes (CNTs) subject to rotating frame. Disturbance in flow is generated by an exponentially stretching sheet. Prescribed heat flux condition is considered. Darcy-Forchheimer relation is employed to characterize the flow in porous space. System of dimensionless equations is obtained by utilizing adequate transformations. Optimal homotopy analysis algorithm is employed for solution development. Physical interpretation of emerging variables on flow fields and physical quantities is discussed. Skin friction coefficient enhances for local porosity parameter, nanoparticle volume fraction and Forchheimer number. Augmentation for heat transfer rate is noticed through solid volume fraction of nanoparticles.

Abstract
Infertile people who suffered from loss of uterine structures and/or functions can be treated through gestational surrogacy or uterus transplantation, which remains challenging due to the ethical and social issues, the lack of donor organs as well as technical and safety risks. One promising solution is to regenerate and reconstruct a bioartificial uterus for transplantation through the engineering of uterine architecture and appropriate cellular constituents. Here, we developed a well-defined system to regenerate a functional rat uterine through recellularization of the decellularized uterine matrix (DUM) patches reseeded with human mesenchymal stem cells (hMSCs). Engraftment of the recellularized DUMs on the partially excised uteri yielded a functional rat uterus with a pregnancy rate and number of fetuses per uterine horn comparable to that of the control group with an intact uterus. Particularly, the recellularized DUMs enhanced the regeneration of traumatic uterine in vivo because of MSC regulation. The established system here will shed light on the treatment of uterine infertility with heterogeneous DUMs/cell resources through tissue engineering in the future.

Published: December 2020

Abstract
While wind power is a low-carbon renewable energy technology with relatively little land footprint, the necessary infrastructure expansion still has land-related environmental impacts. Brazil has seen more than a ten-fold increase in wind power capacity in the last decade. However, little is known about these impacts of wind power generation in Brazil compared to other world regions, although Brazilian wind power infrastructure is concentrated in the least protected ecosystems that are prone to degradation, desertification and species extinction. This study focuses on land-use impacts of past wind power generation development in four Brazilian federal states, covering 80% of the country’s installed capacity. We assessed their spatial installation patterns, associated land-use and land cover change in the period before installation until 2018, and potential alternative installation locations, using a detailed wind turbine location database in combination with a high-resolution land-use and land cover map. In contrast to wind parks built in Europe, we found that 62% of the studied wind park area was covered by native vegetation and coastal sands. Overall, 3.2% of the total wind cluster area was converted from native vegetation to anthropogenic use. Wind parks installed mainly on native vegetation, on average, underwent higher land-use change compared to other wind parks. As Brazil intends to more than double its current wind power capacities by 2029, we explored possibilities to reduce environmental risks due to wind power expansion. We showed that this is feasible by integrating wind parks into human-altered areas, as sufficient wind resources there are available.
Renormalizing Yukawa interactions in the standard model with matrices and noncommutative geometry
Authors: Gesteau Elliott 
Published: December 2020

Abstract
We show that gauge-independent terms in the one-loop and multi-loops β-functions of the standard model can be exactly computed from the Wetterich functional renormalization of a matrix model. Our framework is associated to the finite spectral triple underlying the computation of the standard model Lagrangian from the spectral action of noncommutative geometry. This matrix-Yukawa duality for the β-function is a first hint towards understanding the renormalization of the noncommutative standard model conceptually, and provides a novel computational approach for multi-loop β-functions of particle physics models.

Abstract
In recent years, the domestic study on shale gas has been affected greatly by significant research achievements of overseas marine-facies shale gas exploration and development. In order to study exploration potential of Zhaoxian shale gas of Carboniferous Benxi Formation in Ordos Basin, the petrology, organic geochemistry and gas-bearing capacity of Zhaoxian shale samples from Benxi Formation were investigated. Based on these parameters, the exploration potential of these shales were estimated by applying mathematical statistics and analysing logging response characteristics. Results showed that the Zhaoxian shale was located in the lower part of the Benxi Formation, it was formed in a marine sedimentary environment with a thickness of 15-30m, logging was characterized by higher gamma anomalies and high compensation neutrons. The brittle minerals were mainly quartz, carbonate rock and pyrite, with an average of 36.9%, and a maximum of 50.9%. The total organic carbon (TOC) content was greater than 1% in general and the average value was 2.8%. Organic matter type of the shale samples was mainly type II2 and a few samples were of type II1 organic matter. Vitrinite reflectance values (1.82% on average) showed that shale samples were at mature-high mature stage, which enables good pyrolysis gas generation. The desorbed gas content ranged between 0.34∼2.01 m3/t with an average of 0.99 m3/t. All the evidences indicate that Zhaoxian shale from Carboniferous Benxi formation was of great potential for shale gas exploration.

Published: December 2020

Abstract
The characteristics of sequence stratigraphy, geochemistry and coal petrology of Taiyuan and Shanxi formations of Upper Paleozoic in Huanghua depression are systematically analyzed in this paper, It is considered that the thick coal seams in the study area are formed near the transgressive surface, while the coal seams formed at the most flooding surface are not so thick. The thick coal seams are mostly formed in the transgressive system tract, and the coal seams in the highstand system tract are relatively thin, and the coal seams in the lowstand system tract are hardly developed. There are mainly three coal forming models in the study area: ① the land surface coastal coal forming model; ② the abandoned clastic system tract coal forming model; ③ the shallow water delta coal forming model. The main coal forming model is the epicontinental seashore coal forming mode, and the Taiyuan Formation thick coal seam is mainly formed in the epicontinental seashore coal forming mode, and the Shanxi Formation thick coal seam is mainly formed in the waste clastic coal forming mode.
Discussion about the contribution of water to the shale gas reserves within high-over matured shale rocks

Published: December 2020

Abstract
The shale gas currently exploited in China is mainly featured by high thermal maturity level and the methane concentration is generally more than 95% (v/v). The H/C atomic ratios of residual kerogen gradually decreased with the maturity whereas the source of elemental hydrogen contribution to the shale gas generation within high-over matured shale rocks is still vague. In recent years, some work indicated that the methane generation and its hydrogen isotope characteristics were greatly affected by elemental hydrogen from external water at the over-mature stage in shale rocks. The significance of water should be probed in the processes of geochemical degradation of residual kerogen and hydrocarbon generation in shales. It will be very meaningful to perform the hydrous pyrolysis experiments with heavy water to quantitatively appraise the impact of water on the hydrocarbon generation within shale rocks. A better understanding of the role that water plays on the shale gas generation and enrichment can be hopefully attained.

Published: December 2020

Abstract
The Zhu III Sub-basin is an important petroliferous basin in the Pearl River Mouth Basin. To obtain the evolution of liquid and gaseous hydrocarbon of the kerogen in the Zhu III Sub-basin, a sample of Wenchang formation in the sub-basin was used in the confined pyrolysis experiments in the present study. The results show that the kerogen has very good hydrocarbon generation potential, with the maximum ΣC1-C5 and ΣC6+ yields of 999.69ml/g·TOC and 808.71mg/g·TOC, respectively, at 600°C. To further study the process of the process of hydrocarbon generation in geological conditions of the sub-basin, the burial, temperature, and thermal history are reconstructed. The kerogen of Wenchang formation started to generate oil and gas at 37Ma and 25Ma, respectively. The transformation ratio value of ΣC6+ reached 100% at 14.45Ma, and that of ΣC1-C5 reached 37%, mainly ΣC2-C5, at present.
