A network analysis of cofactor-protein interactions for analyzing associations between human nutrition and diseases

The involvement of vitamins and other micronutrients in intermediary metabolism was elucidated in the mid 1900's at the level of individual biochemical reactions. Biochemical pathways remain the foundational knowledgebase for understanding how micronutrient adequacy modulates health in all life stages. Current daily recommended intakes were usually established on the basis of the association of a single nutrient to a single, most sensitive adverse effect and thus neglect interdependent and pleiotropic effects of micronutrients on biological systems. Hence, the understanding of the impact of overt or sub-clinical nutrient deficiencies on biological processes remains incomplete. Developing a more complete view of the role of micronutrients and their metabolic products in protein-mediated reactions is of importance. We thus integrated and represented cofactor-protein interaction data from multiple and diverse sources into a multi-layer network representation that links cofactors, cofactor-interacting proteins, biological processes, and diseases. Network representation of this information is a key feature of the present analysis and enables the integration of data from individual biochemical reactions and protein-protein interactions into a systems view, which may guide strategies for targeted nutritional interventions aimed at improving health and preventing diseases

Design of software radio

Software Define Radio (SDR) has become a prevalent technology in wireless systems. In SDR some or all of the signal specific handling is implemented in software functions, while other functions like decimation, interpolation, digital up-conversion and digital down conversion are done on reprogrammable Digital Signal Processor or Field Programmable Gate Arrays.Twelve laboratory exercises have been designed to lead the student through the process of using the Universal Software Radio peripheral (USRP) hardware and GNU Radio open source software

Emotion Knowledge and Relational Aggression in Preschoolers

The preschool years are an important time in a child\u27s emotional development. Children learn how to navigate peer relationships and understand the source of others\u27 emotions, one of the most important tasks of this developmental period. Deficits in emotion knowledge have been linked with increased aggressive behaviors and poor peer acceptance. This study\u27s main objective was to clarify whether emotion knowledge is related to relational aggression in young children. In addition, the role of age, sex, siblings, depressed affect, and peer acceptance and rejection was examined in the context of relational aggression. Sixty-six preschool children from ages 3 to 4 were administered Denham\u27s Affective Knowledge Test (DAKT; Denham, 1986), and both preschool teachers and children completed the Preschool Social Behavior Scale-Teacher and Peer Forms (PSBS-T; PSBS-P; Crick et al., 1997) to assess relationally-aggressive behaviors. Results of the study indicated that four-year-old children engage in more relationally-aggressive behaviors as rated by teachers than three-year-old children. In addition, relationally-aggressive preschool boys experience significantly less peer rejection than non-relationally-aggressive preschool boys. Several additional findings involving emotion knowledge, depressed affect, and peer acceptance and rejection approached significant levels

German POWs Make Colorado Home: Coping by Craft and Exchange

From 1943 to 1946, the U.S. government held over 3,000 German POWs at Camp Trinidad in southern Colorado. In 2013 and 2014, archaeological fieldwork, interviews, and archival research were conducted in order to better understand the daily lives of those incarcerated at the camp. The information gathered about artifacts, environmental features, and personal narratives, reveals insights into the lesser known details of the prisoners\u27 lives. Despite the U.S. military rules and regulations and efforts by American personnel within camp, prisoners created goods they wanted or needed. Acquiring the necessary goods was accomplished through modification of available goods, through scavenging the local built or natural environment to craft desired items, and through exchange of goods between the prisoners and their captors. By creating the goods the prisoners wanted or needed, they were not only able to exert their own power within institutional confinement, they also coped and made-do in their temporary home

MWS and FWS Codes for Coordinate-Wise Weight Functions

A combinatorial problem concerning the maximum size of the (hamming) weight set of an $[n,k]_q$ linear code was recently introduced. Codes attaining the established upper bound are the Maximum Weight Spectrum (MWS) codes. Those $[n,k]_q$ codes with the same weight set as $\mathbb{F}_q^n$ are called Full Weight Spectrum (FWS) codes. FWS codes are necessarily ``short", whereas MWS codes are necessarily ``long". For fixed $k,q$ the values of $n$ for which an $[n,k]_q$-FWS code exists are completely determined, but the determination of the minimum length $M(H,k,q)$ of an $[n,k]_q$-MWS code remains an open problem. The current work broadens discussion first to general coordinate-wise weight functions, and then specifically to the Lee weight and a Manhattan like weight. In the general case we provide bounds on $n$ for which an FWS code exists, and bounds on $n$ for which an MWS code exists. When specializing to the Lee or to the Manhattan setting we are able to completely determine the parameters of FWS codes. As with the Hamming case, we are able to provide an upper bound on $M(\mathcal{L},k,q)$ (the minimum length of Lee MWS codes), and pose the determination of $M(\mathcal{L},k,q)$ as an open problem. On the other hand, with respect to the Manhattan weight we completely determine the parameters of MWS codes.Comment: 17 page
