Some studies on the multi-mesh architecture.

In this thesis, we have reported our investigations on interconnection network architectures based on the idea of a recently proposed multi-processor architecture, Multi-Mesh network. This includes the development of a new interconnection architecture, study of its topological properties and a proposal for implementing Multi-Mesh using optical technology. We have presented a new network topology, called the 3D Multi-Mesh (3D MM) that is an extension of the Multi-Mesh architecture [DDS99]. This network consists of n3 three-dimensional meshes (termed as 3D blocks), each having n3 processors, interconnected in a suitable manner so that the resulting topology is 6-regular with n6 processors and a diameter of only 3n. We have shown that the connectivity of this network is 6. We have explored an algorithm for point-to-point communication on the 3D MM. It is expected that this architecture will enable more efficient algorithm mapping compared to existing architectures. We have also proposed some implementation of the multi-mesh avoiding the electronic bottleneck due to long copper wires for communication between some processors. Our implementation considers a number of realistic scenarios based on hybrid (optical and electronic) communication. One unique feature of this investigation is our use of WDM wavelength routing and the protection scheme. We are not aware of any implementation of interconnection networks using these techniques.Dept. of Computer Science.

Confirmatory Silos in COVID-19-Related Attitudes and Behaviors

Confirmation bias is a pervasive phenomenon. We hypothesize that confirmation bias plays a role in our choice of news media, which may lead to the creation of confirmatory silos. These silos may create closed feedback loops that may shape attitudes and behavior. The purpose of this study was to explore the extent to which these confirmatory silos may extend to COVID-19 attitudes and behavior. This correlational survey study was completed by 389 USF undergraduates from psychology classes. Participants provided information about attitudes toward COVID-19, self-reported COVID-related behavior, cable media news sources, and political outlook (conservative vs. liberal). We found that liberal outlooks lean toward consumption of more liberal media (CNN, NPR, MSNBC), while conservative outlooks lean toward viewing of more conservative media (Fox News). As expected, we found that consumption of more liberal news was associated with higher levels of COVID-19 worry, while viewing of more conservative media predicted less COVID-19 worry. This relationship extended to behavior. Viewing of more liberal media was also associated with more self-reported COVID-19 protective behaviors (e.g. social distancing and hand washing), while consumption of more conservative media correlated with fewer protective behaviors. These findings provide evidence of confirmatory silos in the context of COVID-19. Attitudes and behaviors were consistent with the messages within the silo. Silos may reinforce a single point of view and limit awareness of alternative points of view

Exploring therapeutic potential of Woodfordia fruticosa (L.) Kurz leaf and bark focusing on antioxidant, antithrombotic, antimicrobial, anti‐inflammatory, analgesic, and antidiarrheal properties

Abstract Background and Aims The study aimed to evaluate the pharmacological properties of methanolic extracts of leaves and barks of Woodfordia fruticosa (L.) Kurz (family: Lythraceae) focusing on antioxidant, thrombolytic, anti‐inflammatory, antibacterial, analgesic, and antidiarrheal effects. Methods 1,1‐Diphenyl‐2‐picrylhydrazyl (DPPH) free radical scavenging assay, clot lysis, disc diffusion, and membrane stabilizing methods were employed to assess in vitro antioxidant, thrombolytic, antibacterial, and anti‐inflammatory properties of the leaf and bark methanolic extracts (ME) of W. fruticosa and different organic solvents, that is, petroleum ether (PE), dichloromethane (DCM), chloroform (CL), and aqueous (AQ) fractions. In addition, in vivo central and peripheral analgesic and antidiarrheal activities of both crude extracts were evaluated at two doses (200 and 400 mg/kg of body weight [bw]). Results All the extracts and fractions showed promising antioxidant properties by scavenging DDPH free radicals with IC50 of 6.11–20.79 μg/mL. AQ fraction (41.24%) of leaves and ME (44.90%) of bark exerted notable in vitro thrombolytic activity. The CL fraction of leaves and AQ fraction of the bark showed 43.16% and 45.37% inhibition of RBC hemolysis, respectively, compared to the inhibition of RBC hemolysis by aspirin in a hypotonic‐induced membrane stabilizing assay. Besides, both extracts were observed to provide significant (p < 0.001) central and peripheral analgesic responses at both doses of 200 and 400 mg/kg bw. Furthermore, both doses of bark extract (p < 0.001) and the 400 mg/kg bw of leaf extract (p < 0.05) were observed to possess statistically significant antidiarrheal activity. Additionally, in an in vivo acute toxicity investigation, both extracts had a median lethal dose (LD50) greater than 5000 mg/kg bw, indicating their safety level. Conclusion The current study proves the ethnomedicinal uses of W. fruticosa; however, further studies are required for phytochemical screening to isolate the responsible bioactive compounds and discover the lead molecules from the plant species
