Abstract Intrinsic plasticity, a fundamental process enabling neurons to modify their intrinsic properties, plays crucial role in shaping neuronal input‐output function and is implicated various neurological psychiatric disorders. Despite its importance, the underlying molecular mechanisms of plasticity remain poorly understood. In this study, new ubiquitin ligase adaptor, protein tyrosine phosphatase receptor type N (PTPRN), identified as regulator excitability context temporal lobe...
High-voltage electrical pulse (HVEP) technology is a useful method to improve the pore structure of coal. However, breakdown voltage coal very high; therefore, it necessary conductivity first decrease its before subjecting HVEP. In this work, solution NaCl was used for ameliorating Linhua anthracite and Hongliu bituminous Both energy consumed by sample saturated with decreased. The raw (RCS) 3.44 2.88 times that NaCl, respectively. RCS 11.82 8.21 solution, Scanning electron microscopy images...
High-voltage thermal breakdown has great potential application in permeability enhancement of coal seam. The characteristics the channel, element, porosity and microscopic petrography under high-voltage electric load were experimentally studied. interior left apparent tracks due to current burning with high temperature. percentage C, O, Al, Fe, Si had slightly decreased, while content element N increased obviously. Low-pressure nitrogen gas adsorption (LP-N2GA) mercury intrusion analysis...
A thermal-state model experimental study was performed in lab to investigate the thermal performance of a wet cooling tower with different kinds filling layout patterns under windless and 0.4 m/s crosswind conditions. In this paper, contrast analysis focused on comparing uniform pattern one kind optimal non-uniform when environmental speed is 0 m/s. The results proved that conditions, heat transfer coefficient total rejection circulating water for can enhance by approximately 40% 28%,...
The low gas permeability of coal formations with limited pores and fractures leads to difficulty in coalbed methane exploration. High-voltage electrical pulse has a potential application enhanced recovery. In this study, we discuss the microscopic characteristics anthracite coals treated by high-voltage pulse. We find that C, O, other elements constituting oxygenic groups, which mainly account for adsorption, decreased slightly after treatment, indicating elemental variation may have little...
Hydraulic slotting is a technique to enhance coal bed methane (CBM) recovery and prevent gas disasters. The drilling fields are usually arranged in floor roadway rather than roof roadway, but submerged jet effects caused by hydraulic have not been carried out extensively. Concerning this issue, paper conducted series of numerical simulation physical experiments on roadway. It shown that when the impact load middle- high-pressure water applied sample, downlink borehole can cause much stronger...
Mechanical helical phased array antenna (HPAA) realizes microwave beam directing by mechanically rotating the element. Measuring and calibrating phase of HPAA, which can be simplified to measure calibrate each element, is significant important evaluate performance. To realise fast measurement calibration element antenna, this paper proposed a line-scan machine vision (MV) strategy. A prototype MV system combining camera guide rail structure acquire image designed proposed. Phase recognition...
An accurate estimation of soil permeability is essential in geotechnical engineering. Transparent provides a promising experimental material to visualize pore-scale fluid flow, although the characteristic transparent remains unclear. As result replacement and solid phase, coefficient usually several times or even more than ten smaller that natural with same particle size distribution porosity. Fused quartz sand used as phase this proposed soil, which exhibits similar mechanical behavior but...
During the underground mining process, various coal seams with different bedding structures are often encountered. The presence of is one primary factors that influence strength and deformation characteristics seam then affect gas extraction disaster prevention. However, there still a lack mechanical properties rock structural anisotropy influenced by structures. In this study, numerical models were established using particle flow code method to simulate specimens containing varying...
Bend structures in process industries can enhance gas explosions. Many researchers have studied their effects on flame propagations or overpressure evolutions with experiments numerical simulations. In this work, three bends different angles ranging from obtuse to acute were examined, and the effect of bend positions explosions was also experiments. It found that peak under experienced stages, i.e. a slight downtrend before bend, sudden uptrend after following downtrend. The explosion...
We propose a design for simple broad-angle polarization beam splitter (PBS) consisting of two rows dielectric cylinders with different space periods. The finite-difference time-domain method simulations show that TM polarized light is reflected totally by this PBS but TE passes through it freely in broad incident angle range (from −50° to 50°). can work over wide frequency 0.22 × ( c / ) 0.28 )) high efficiency. Moreover, the structure has novel capability tolerance large random disorder,...
The propagation characteristics of premixed methane/air explosion under different filling ratios (20%, 30%, 40%, 50%, 60%, and 100%) were studied using an experimental system. results indicate that the peak overpressure showed a decreasing trend at initial stage but then increasing until reaching its maximum value ratios. As propagated to open end, downtrend. At this point, flame speed initially increased along pipe dropped dramatically. In addition, with increase ratio. However, when ratio...
<title>Abstract</title> Understanding the hypergravity effect on seepage and internal erosion is essential precondition for dam hydraulic disaster modeling using geotechnical centrifuges. Soil column testing useful to bridge this knowledge gap, but previous attempts did not provide adequate functionality in centrifuge environments. This study develops a centrifuge-available apparatus soil tests (CASIE). CASIE ensures consistent stable circulating water supply with no less than 34 000 ml/min...
