Abstract
A Super Tau Charm Facility (STCF) is one of the major
options for the accelerator-based high energy project in China in
the post-BEPCII era, and its R&D program is underway. The proposed
STCF will span center of mass energies (√(s)) ranging from 2
to 7 GeV with a peaking luminosity above 0.5×
1035 cm−2 s−1 at √(s)=4.0 GeV, and will
provide a unique platform for tau-charm physics and hadron physics.
In order to evaluate the physical potential capabilities and
optimize the detector design, a fast simulation package has been
developed. This package takes as inputs the response of physical
objects in each sub-system of the detector including resolution,
efficiency as well as related variables for the kinematic fit and
the secondary vertex reconstruction algorithm. It can flexibly
adjust the responses of each sub-detector system and is a critical
tool for the STCF R&D program.
Recharge from glacial meltwater is critical for alpine springs and their microbiomes
Authors: Miller Jordyn B , Frisbee Marty D , Hamilton Trinity L , Murugapiran Senthil K 
Published: March 2021

Abstract
The importance of glacier meltwater as a source of mountain-block recharge remains poorly quantified, yet it may be essential to the integrity of alpine aquatic ecosystems by maintaining baseflow in streams and perennial flow in springs. We test the hypothesis that meltwater from alpine glaciers is a critical source of recharge for mountain groundwater systems using traditional stable isotopic source-identification techniques combined with a novel application of microbial DNA. We find that not only is alpine glacier meltwater a critical source of water for many springs, but that alpine springs primarily supported by glacial meltwater contain microbial taxa that are unique from springs primarily supported by seasonal recharge. Thus, recharge from glacial meltwater is vital in maintaining flow in alpine springs and it supports their distinct microbiomes.

AbstractThe relevance of the study is stipulated by the necessity for determining of optimum composition of water-fuel mixture (WFM) for a spark-ignition internal combustion engine with electronic control. The objective of the study is the determining of the optimum composition of water-fuel mixture (WFM) during the operation of a VAZ-21114 engine which allows for the best quantitative performance specifications. For this purpose, an experimental test fixture was developed, consisting of a KI-2139 electrical brake bench with a pendulum arm machine and an “AVTOTEST-02.03” 5-component gas analyzer, with equipment for bench testing in accordance with the requirements of GOST 14846-81 “Automotive engines. Bench test methods”. As a result, for the first time, optimum quantitative WFM composition was obtained for operation of VAZ-21114 spark-ignition engine with electronic control providing for the best quantitative performance specifications. The analysis of the obtained data demonstrates lowering of the concentration of toxic exhaust gas (EG) components of the engine, specific effective (ge) and hourly (Gm) fuel consumption rate, as well as the EG temperature (Toe) during its operation by the external rpm vs. load curve within the utilization range of WFM with 0 to 12% water content. At water content growth in the WFM from 12 to 20%, a growth of carbon monoxide (CO) and unburnt hydrocarbons (CH) in the EG is observed, as well as a growth ofgeandGm. The minimum quantitative values of the parametersCO, CH, NOx, Toe, geandGmwere: 6.0 and 1.65% ofCOat water content in WFM of 10 and 13%, respectively; 173 and 142.5 ppm ofCHat 10% water content in WFM; 113 and 215 ppm ofNOxandToe650 and 730 К at up to 20% water content in WFM;ge330 and 303 g/kWh at 12.5 and 11.5% water content in WFM, respectively,Gm6.5 kg/h at 11.5% water content in WFM. The maximum quantitative value of the effective engine powerNeof 44.2 kW was obtained with WTM with 20% water content. The obtained results demonstrate that, for the operation of a spark-ignition type VAZ-21114 engine with electronic control, the WTM should contain 9…12% water as an optimum providing for achievement of the best quantitative performance values.

Abstract
Rotary screw machines (RSM) are widely known as multipurpose vehicles. RSM easily overcome impassable swamps, snow-covered, off-road, ice surface. A significant problem for the creators of vehicles with rotors is the high vibration loads on the operator and machine units, which require multiple experimental studies. A scaled-down model of a vehicle is often used for experiments. The model of the RSM is included in the experiment, replacing not only the object of research, but also the conditions in which it is studied. Strengthening the role of the theoretical side of research, there is a connection between the formulation of the experiment and its results with the object of research. Calculation and calculation of the elements of proportionality is a hard necessity. The article proposes a complex for calculating scale factors when testing vibration loading of machines equipped with screw rotors.

A study on technologies that enable high-speed communication regardless of the interface standard between the host devices and peripheral devices
Authors: Jung So Ki 
Published: March 2021

Abstract
Recently, I/O interfaces for connecting a computer to peripheral devices have emerged to provide 10Giga services for communication companies. Therefore, Intel has developed Thunderbolt cables, which enable electrical signals and high-speed data transfer to facilitate 10Giga services. Thunderbolt is a type of input–output interface that is used to connect computers and peripherals. It is capable of high-speed input/output(I/O), incurs lower overheads than USB, and supports data, images, and voice simultaneously. As these are very recent standards, they have not been applied to many computers. Moreover, no device exists to use interfaces having a different protocols while differentiating between Thunderbolt and USB devices. Therefore, if both interfaces are mutually incompatible, the user must utilize Thunderbolt or USB devices separately. For this reason, a device that automatically identifies Thunderbolt or USB and automatically adapts to the user’s environment is required. In this study, Thunderbolt MAC and a MAC are alternately connected to each other via an electrical Multiplexer to auto detect link information and connect to Host. Then, based on the determined result, the Thunderbolt to PCIe bridge or the USB to PCIe bridge is electrically connected to the PCIe BUS to which the Multiplexer is connected.

Authors: Huang T Y , Chen W J 
Published: March 2021

Abstract
This paper used sequential quadratic programming (SQP) method to obtain the optimal obstacle avoidance posture and end position of a 7-axis robotic manipulator. By applying restraining conditions, obstacle information, and finishing point coordinates, a homogeneous transformation matrix was firstly used to construct a space for limited movement for the first and sixth axes of the robotic manipulator. Subsequently, we determined whether the terminal point was within reach of the robotic manipulator and calculated the angle of each axis. Finally, the MATLAB software was used to conduct a simulation and verification. In this study, the SQP method was used to introduce inequality constraints into the computation and conducted the iterative method. The simulation results revealed that the method can obtain avoidance of obstacle postures and select optimal values from the iteration results of multiple initial values to avoid the local optimal problem. Overall, the research findings are that the functions and applicability of the 7-axis robotic manipulator can be extended in industry when applied in future intelligent manufacturing.
