Notes on monotonically metacompact generalized ordered spaces
In this paper, we show that any generalized ordered space X is monotonically (countably) metacompact if and only if the subspace X - { x } is monotonically (countably) metacompact for every point x of X and monotone (countable) metacompact property is hereditary with respect to convex (open)…

Discussion on Reinforcement Mechanism and Construction Technology of Pressurized Vacuum Preloading
Based on the basic theory of vacuum preloading, this paper proposes an good effect of pressurized vacuum preloading in which the high pressure gas results in tiny cracks between the air pressurized pipe and band drain. Therefore additional drainage paths are introduced to improve the permeability…

Stability of Volume Inequalities Associated with Lp Zonoids
In this paper, we establish stability versions of the volume inequalities associated with Lp zonoids. These results, particularly for the case 1≤p≤2, extend the case p=1 previously obtained by Brazitikos and Giannopoulos. As applications, we derive several stability inequalities for Lp isotropic…

Cardioprotective effect of alpha-lipoic acid and its mechanisms
Alpha-lipoic acid (ALA), a sulfur-containing fatty acid ubiquitously present in living organisms, is a cofactor that covalently binds to mitochondrial enzymes, such as pyruvate dehydrogenase (PDH) and oxoglutarate dehydrogenase (OGDH). ALA is not only crucial to the function of major enzymes that…

Responses and Receptive Fields of Amacrine Cells and Ganglion Cells in the Salamander Retina
Retinal amacrine cells (ACs) and ganglion cells (GCs) have been shown to display large morphological diversity, and here we show that four types of ACs and three types of GCs exhibit physiologically-distinguishable properties. They are the sustained ON ACs; sustained OFF ACs; transient ON-OFF ACs…

Receptive Fields of Retinal Bipolar Cells Are Mediated by Heterogeneous Synaptic Circuitry
Center-surround antagonistic receptive field (CSARF) organization is the basic synaptic circuit that serves as elementary building blocks for spatial information processing in the visual system. Cells with such receptive fields converge into higher-order visual neurons to form more complex…

Synthesis of Fluorescent Copper Nanomaterials and Detection of Bi(3+)
Based on the aggregation-induced luminescence of glutathione-protected non-noble metal copper nanoparticles (GSH-CuNPs), a fluorescence method for the rapid detection of bismuth (Bi(3 +)) was developed. The fluorescence intensity of GSH-CuNP solution is good, and the fluorescence can be quenched in…

Antagonistic surround responses in different cones are mediated by feedback synapses from different horizontal cells
Cone photoreceptors are the first neurons along the visual pathway that exhibit center-surround antagonistic receptive fields, the basic building blocks for spatial information processing in the visual system. The surround responses in cones are mediated by the horizontal cells (HCs) via multiple…
