A Reaction-Diffusion-Based Coding Rate Control Mechanism for Camera Sensor Networks

A wireless camera sensor network is useful for surveillance and monitoring for its visibility and easy deployment. However, it suffers from the limited capacity of wireless communication and a network is easily overflown with a considerable amount of video traffic. In this paper, we propose an autonomous video coding rate control mechanism where each camera sensor node can autonomously determine its coding rate in accordance with the location and velocity of target objects. For this purpose, we adopted a biological model, i.e., reaction-diffusion model, inspired by the similarity of biological spatial patterns and the spatial distribution of video coding rate. Through simulation and practical experiments, we verify the effectiveness of our proposal

Bis(1H-imidazole-κN 3){2,2′-[propane-1,2-diylbis(nitrilo­methyl­idyne)]diphenolato-κ4 O,N,N′,O′}iron(III) perchlorate

The title compound, [Fe(C17H16N2O2)(C3H4N2)2]ClO4, consists of monomeric [Fe(salmen)(HIm)2]+ cations {salmen is the 2,2′-[propane-1,2-diylbis(nitrilo­methyl­idyne)]diphen­olate dianion and HIm is 1H-imiazole} and perchlorate anions. In the cation, the Fe3+ ion is octahedrally coordinated by two N atoms and two O atoms from a tetra­dentate salmen anion and two N atoms from two Him mol­ecules. These ligands are coordinated to the iron ion in a direction perpendicular to the [Fe(salmen)]+ coordination plane. The benzene ring planes in the salmen ligands are oriented nearly parallel to one another inter­molecularly [dihedral angle = 6.36 (3)°]. The dihedral angle between the mean planes through the imidazole rings in the cation is 76.9 (2)°. In the crystal, N—H⋯O inter­actions link the mol­ecules into a one-dimensional double chain running along [101] and C—H⋯O inter­actions link the double chains into a two-dimensional network, running parallel to the ac plane

Rikkunshito Ameliorates Cancer Cachexia Partly through Elevation of Glucarate in Plasma

Cancer cachexia, which is characterized by decreased food intake, weight loss and systemic inflammation, increases patient’s morbidity and mortality. We previously showed that rikkunshito (RKT), a Japanese traditional herbal medicine (Kampo), ameliorated the symptoms of cancer cachexia through ghrelin signaling-dependent and independent pathways. To investigate other mechanisms of RKT action in cancer cachexia, we performed metabolome analysis of plasma in a rat model bearing the Yoshida AH-130 hepatoma. A total of 110 metabolites were detected in plasma and RKT treatment significantly altered levels of 23 of those metabolites in cachexia model rats. Among them, glucarate, which is known to have anticarcinogenic activity through detoxification of carcinogens via inhibition of β-glucuronidase, was increased in plasma following administration of RKT. In our AH-130 ascites-induced cachexia rat model, administration of glucarate delayed onset of weight loss, improved muscle atrophy, and reduced ascites content. Additionally, glucarate reduced levels of plasma interferon-γ (IFN-γ) in tumor-bearing rats and was also found to suppress LPS-induced IFN-γ expression in splenocytes in vitro. These results suggest that glucarate has anti-inflammatory activity via a direct effect on immune host cells and suggest that RKT may also ameliorate inflammation partly through the elevation of glucarate in plasma
