Raman spectroscopy is a key technique for the identification and structural interrogation of molecules. It generally exploits changes in vibrational state within individual molecules which produce, in the scattered light, frequencies that are absent in the incident light. Considered as a quantum optical process, each Raman scattering event involves the concurrent annihilation and creation of ph...

Approximate nearest neighbor search is a technique which greatly reduces processing time and required amount of memory. Generally, there are the relationships of trade-off among accuracy, processing time and memory amount. Therefore, analysis on the relationships is an important task for practical application of the approximate nearest neighbor search method. In this paper, we construct a model...

A positive correlation between the sizes of plants and the sizes of their nearest neighbors has been observed in many plant populations and is most often attributed to variation in microsite quality. We demonstrate another potentially important cause, using a simple spatial simulation model in which a plant's size is determined by its available area plus stochastic variation. If the spatial arr...

Natural phenomena frequently involve a very large number of interacting molecules moving in confined regions of space. Cellular transport by motor proteins is an example of such collective behavior. We derive a deterministic compartmental model for the unidirectional flow of particles along a one-dimensional lattice of sites with nearest-neighbor interactions between the particles. The flow bet...

The structure of N,N'-bis(2-hydroxybenzylidene)-2,2-dimethyl-1,3-propanediamine, C19H22N2O2, has been studied at low temperature (120K) by means of single-crystal X-ray diffraction. Solving the structure shows an orthorhombic unit cell, with P212121 space group, Z = 4, a = 6.1046 (4) Å, b = 15.8349 (11) Å, c = 17.2898 (12) Å and V = 1671.3 (2) Å. There are two relatively strong hydrogen bonds (...

recently several 1,3,4-oxadiazole derivatives were identified as potentially active antimycobacterial agents. various 5-aryl-2-thio-1,3,4-oxadiazoles have been reported having good antimycobacterial activity against mycobacterium tuberculosis h37rv (atcc 27294). in this paper we report 3d qsar studies for the 41 molecules of 1,3,4-oxadiazoles by using k-nearest neighbor molecular field analysis...

Advances in mobile technologies and devices has changed the way users interact with devices and other users. These new interaction methods and services are offered by the help of intelligent sensing capabilities, using context, location and motion sensors. However, indoor location sensing is mostly achieved by utilizing radio signal (Wi-Fi, Bluetooth, GSM etc.) and nearest neighbor identificati...

Deep neural networks (DNNs) enable innovative applications of machine learning like image recognition, machine translation, or malware detection. However, deep learning is often criticized for its lack of robustness in adversarial settings (e.g., vulnerability to adversarial inputs) and general inability to rationalize its predictions. In this work, we exploit the structure of deep learning to ...

In this review/perspective article we show how the dipole moment of a single molecule in cluster can be calculated and used for describing polarization effect. Additionally, review accuracy calculation several simple protic aprotic molecules. It is shown that polar (water, methanol, formamide, acetone acetonitrile) molecules neighborhood cation increased primarily by from bare electrostatic cha...

Background: Gap junctions composed of connexins (Cx) are functional in cell defense by propagation of toxic/death molecules to neighboring cells. Hippocampus, one of the brain regions with particular vulnerability to damage, has a wide network of gap junctions. Functional response of astrocytic Cx30 and neuronal Cx32 to hippocampal damage is unknown. Methods: We infused lipopolysaccharide (LPS)...
