Abstract:
Visual corona tests have been broadly applied for identifying the critical corona points of diverse high-voltage devices, although other approaches based on partial discharge or radio interference voltage measurements are also widely applied to detect corona activity. Nevertheless, these two techniques must be applied in screened laboratories, which are scarce and expensive, require sophisticated instrumentation, and typically do not allow location of the discharge points. This paper describes the detection of the visual corona and location of the critical corona points of a sphere-plane gap c

Abstract:
Voltage-gated calcium channels (VGCC) are key to many biological functions. Entry of Ca2+into cells is essential for initiating or modulating important processes such as secretion, cell motility, and gene transcription. In the retina and other neural tissues, one of the major roles of Ca2+-entry is to stimulate or regulate exocytosis of synaptic vesicles, without which synaptic transmission is impaired. This review will address the special properties of one L-type VGCC,CaV1.4, with particular emphasis on its role in transmission of visual signals from rod and cone photoreceptors (hereafter cal

Abstract Background We have previously reported that nicotine enhances recognition memory (Esaki et al. 2021), which may be mediated by increased spiking activity of medial prefrontal cortex (mPFC) layer V pyramidal cells via suppressing voltage-dependent potassium (Kv) channels. However, it remains unclear which subtype of Kv channels is associated with this effect of nicotine. Additionally, although nicotine has been suggested to affect synaptic transmission (Lambe et al. 2003), whether this effect is involved in recognition memory enhancement also remains undiscovered.

Abstract:
AbstractIn the primate retina, parasol ganglion cells contribute to the primary visual pathway via the magnocellular division of the lateral geniculate nucleus, display ON and OFF concentric receptive field structure, nonlinear spatial summation, and high achromatic temporal–contrast sensitivity. Parasol cells may be homologous to the alpha-Y cells of nonprimate mammals where evidence suggests that N-methyl-D-aspartate (NMDA) receptor-mediated synaptic excitation as well as glycinergic disinhibition play critical roles in contrast sensitivity, acting asymmetrically in OFF- but not ON-pathways.

Abstract:
This research aims to analyze the implementation of a fuzzy logic-based approach in improving the diagnosis of power transformer oil deterioration, which is critical for maintaining the efficient performance and operational life of transformers. Traditional diagnoses are based on strict measurements that do not account for the factors of variability and uncertainty of the actual data. In this article, we perform six different types of tests in this regard, and data have been collected during the period of 2021 to 2022 of 188 power transformer failures in the New KotLakhpat Lahore unit, whose v

Abstract:
Peptide toxins are invaluable tools for studying the structure and physiology of ion channels. Pseudechetoxin (PsTx) is the first known peptide toxin that targets cyclic nucleotide–gated (CNG) ion channels, which play a critical role in sensory transduction in the visual and olfactory systems. PsTx inhibited channel currents at low nM concentrations when applied to the extracellular face of membrane patches expressing olfactory CNGA2 subunits. Surprisingly, 500 nM PsTx did not inhibit currents through channels formed by the CNGA3 subunit from cone photoreceptors. We have exploited this differe

Abstract:
Ca2+ influx through Cav1.4 L-type Ca2+ channels supports the sustained release of glutamate from photoreceptor synaptic terminals in darkness, a process that is critical for vision. Consistent with this role, Cav1.4 exhibits weak Ca2+-dependent inactivation (CDI)—a negative feedback regulation mediated by Ca2+-bound calmodulin (CaM). CaM binds to a conserved IQ domain in the proximal C-terminal domain of Cav channels, but in Cav1.4, a C-terminal modulatory domain (CTM) disrupts interactions with CaM. Exon 47 encodes a portion of the CTM and is deleted in a Cav1.4 splice variant (Cav1.4Δex47) t

Introduction Sodium-ion batteries (NIBs) are attracting an attention because of their abundant raw material resources and low material costs. In particular, the recent surge in lithium prices has led to a demand for alternatives to lithium-ion batteries (LIBs), which accelerates moves toward the practical use of NIBs. The major issue for their practical application is its lower energy density than that of LIBs. One of the critical challenges for improving the energy density of NIBs is the difficulty to handle high-voltage positive electrodes. This difficulty is attributed to the higher operati

Like Kraftwerk, Cabaret Voltaire’s music was influenced by the artistic movements of the twentieth century (most prominently Dada) and drew upon modernist techniques. Especially significant in this regard was their location within post-industrial Sheffield and the ideologies of post-punk more generally. This di
