MeV Tau Neutrino in Gauge Mediated Supersymmetry Breaking Model

A supersymmetric model which naturally accommodates MeV tau neutrino within the framework of gauge mediated supersymmetry breaking is described. The lepton number violation is originally introduced in the messenger sector of the theory. A large slepton-Higgs mixing mass and a small lepton-higgsino mixing mass are generated at one-loop. Scalar tau neutrino has non-vanishing vacuum expectation value. These result in a non-zero \nu_{\tau} mass which is in the range of (1-10) MeV.Comment: 18 pages, latex, two figure

Neovesical-Urethral Anastomotic Stricture Successfully Treated by Ureteral Dilation Balloon Catheter

Neovesical-urethral anastomotic stricture is a complication of orthotopic neobladder, with a reported incidence of 2.7% to 8.8%. Strictures of the neovesico-urethral anastomotic site can be treated with regular self-dilation, but high-grade strictures require a surgical procedure involving incision by electrocautery or cold knife. Here we describe a grade III neovesical-urethral anastomotic stricture after an orthotopic bladder substitution that was successfully treated by use of a ureteral dilation balloon catheter

Nano/Microâ Structured Si/C Anodes with High Initial Coulombic Efficiency in Liâ Ion Batteries

One of the major challenges for designing highâ capacity anode materials is to combine both Coulombic efficiency and cycling stability. Herein, nano/microâ structured Si/C composites are designed and synthesized to address this challenge by decreasing the specific surface area and improving the tap density of Si/C materials. An ultrahigh initial Coulombic efficiency of 91.2â % could be achieved due to a proper particle size, low specific surface area, and optimized structure. The nano/microâ structured Si/C anodes exhibit excellent cycling stability with 96.5â % capacity retention after 100 cycles under a current density of 0.2â Aâ gâ 1.An ode to excellence: Nano/microâ structured Si/C materials were designed and synthesized on a large scale. The asâ obtained Si/C anodes exhibit excellent electrochemical properties in terms of specific capacity, Coulombic efficiency, and cycling stability.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/137602/1/asia201600067-sup-0001-misc_information.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/137602/2/asia201600067.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/137602/3/asia201600067_am.pd

Dynamic modelling of flexibly supported gears using iterative convergence of tooth mesh stiffness

This paper presents a new gear dynamic model for flexibly supported gear sets aiming to improve the accuracy of gear fault diagnostic methods. In the model, the operating gear centre distance, which can affect the gear design parameters, like the gear mesh stiffness, has been selected as the iteration criteria because it will significantly deviate from its nominal value for a flexible supported gearset when it is operating. The FEA method was developed for calculation of the gear mesh stiffnesses with varying gear centre distance, which can then be incorporated by iteration into the gear dynamic model. The dynamic simulation results from previous models that neglect the operating gear centre distance change and those from the new model that incorporate the operating gear centre distance change were obtained by numerical integration of the differential equations of motion using the Newmark method. Some common diagnostic tools were utilized to investigate the difference and comparison of the fault diagnostic results between the two models. The results of this paper indicate that the major difference between the two diagnostic results for the cracked tooth exists in the extended duration of the crack event and in changes to the phase modulation of the coherent time synchronous averaged signal even though other notable differences from other diagnostic results can also be observed

Thermochemical liquefaction of agricultural and forestry wastes into biofuels and chemicals from circular economy perspectives

Waste produced in various fields and activities in society has been increasing, thereby causing immediate environmental harm and a serious-global problem. Recently, the attitude towards waste has changed along with innovations making waste as a new resource. Agricultural and forestry wastes (AFWs) are globally produced in huge amounts and thought to be an important resource to be used for decreasing the dependence on fossil fuels. The central issue is to take use of AFW for different types of products making it a source of energy and at the same time refining it for the production of valuable chemicals. In this review, we present an overview of the composition and pretreatment of AFINs, thermochemical liquefaction including direct liquefaction and indirect liquefaction (liquid products from syngas by gasification) for producing biofuels and/or chemicals. The following two key points were discussed in-depth: the solvent or medium of thermochemical conversion and circular economy of liquid products. The concept of bio-economy entails economic use of waste streams, leading to the widened assessment of biomass use for energy where sustainability is a key issue coined in the circular economy. The smart use of AFWs requires a combination of available waste streams and local technical solutions to meet sustainability criteria. (C) 2020 Published by Elsevier B.V.Peer reviewe

Transcatheter Closure of Multiple Atrial Septal Defects With the Amplatzer Device

Percutaneous device occlusion of secundum atrial septal defect (ASD) has become an accepted alternative to surgical repair. A variety of devices have been used successfully. However, all of them have limitations. We report our experience with two devices used to close multiple ASDs
