The significance of interconnection networks extends beyond the semiconductor industry, becoming integral to industrial engineering, particularly in the era of the Internet of Things (IoT). Both sectors share a strategic emphasis on developing sophisticated networks to enhance performance and scalability. Techniques such as Cartesian product fusion have led to the development of novel interconnected networks, addressing the demand for high-speed communication. The novel network topology, including the Torus-Enhanced Butterfly (TREB) network, is developed by the Cartesian product of the Torus (TR) and Enhanced Butterfly (EB) networks and holds unexplored aspects, particularly concerning the existence of Hamiltonian paths. The objective of this study is to devise a methodology for identifying k-Hamiltonian paths in an extensive TREB network. Contributions include theoretical and algorithmic proofs of Hamiltonian path existence using a hybrid approach. This approach divides the large TREB network graph into four EB subgraphs, and from each subgraph, all Hamiltonian paths are sought using the brute force method as a subsolution. Next, a dynamic programming-based algorithm is used to connect the Hamiltonian paths in these four subgraphs into a complete Hamiltonian path in the TREB network. The experiments reveal several properties of the TREB network that can only be derived through algorithmic approaches. These include the exact number of paths, which can be found from a valid permutation arrangement of the EB subgraphs, reaching approximately one billion paths, and the sequence of nodes forming Hamiltonian pathways.

 

Keywords: Hamiltonian paths, torus network, butterfly network, interconnection network, exact algorithms.

The One Health approach considers the interdependence of human, animal, and environmental health because 70% of diseases affecting humans are mainly in animals. Water serves as a vehicle for the transmission of these diseases. Consequently, monitoring the quality of water for human consumption is crucial, constituting an activity of the environmental health units of the Peruvian Ministry of Health. In 2019, water quality monitoring was conducted in the province of Chucuito, Puno Region, to determine the quality of drinking water for human consumption under the One Health approach. The physicochemical analysis indicated that the parameters were within normal limits, except for residual chlorine, which was completely absent. Microbiological analysis revealed total coliforms and E. coli. These findings impact the responsible production of water for human consumption. According to water quality regulations in Peru, this water has fecal contamination, posing a high microbiological risk and rendering it unsuitable for human consumption. Urgent disinfection is required. These results highlight the breakdown of the human–environment–animal interface of the One Health approach, putting public health at risk.

 

Keywords: One Health, public health, risk, water quality, disinfection.

The dominant axial force on reinforced concrete bridge columns may affect the ability of pillars to respond to various lateral excitations. This study aimed to analyze the strength of concrete, tensile behavior, and shear strength in the pillar structure of a bridge. The method used to identify the behavior of pillars is to separately analyze the internal capacity of the pillars according to the characteristics of concrete and steel quality, cross-sectional shape, and the configuration of the reinforcement installed in three sections along the pillar height. By checking the adequacy of the lap joints and the length of reinforcement distribution, we assume that the dominant pillar is in tension or compression. We also assume that the dominance of tension in the reinforcement joints is in anticipation of a tensile response in the reinforcement joints when bending behavior is dominant (for tall pillars). Curvature: Analyzing the relationship of force–lateral displacement by simulating the height of the pillars from 1 to 5 m and comparing it with the shear capacity of the pillars so that a confining reinforcement spacing of 50 mm is obtained both on the precast pile and the additional cast in situ pier has been increasing the compressive strength and strain of the pillars so that with a factored axial compressive force of 730 kN, it produces compressive stress at the effective cross-section of the pillar of 13 MPa, which means that the strength of the concrete on the pillars is still sufficient. The shear capacity of the pillar obtained by factored loading is from 17 to 86 kN, so the pillar is still safe from shear failure along its height.

 

Keywords: bridge, capacity, connection, precast pillar.

This study has two main objectives: 1) investigating the internal control factors that impact the operational efficiency of the Revenue Office in Thailand, and 2) assessing the organizational performance of Revenue Office personnel in Thailand, segmented according to their diverse work experiences. This study gathered data from 2,130 personnel of the Regional Revenue Office in Thailand, employing questionnaires as the primary data collection tool. The data were then analyzed to examine the relationships and impacts of various variables using multiple regression analysis and the test of difference of means (ANOVA), with a focus on statistical significance at the 0.05 level. The analysis revealed that internal control factors within the control environment, control activities, and information and communication significantly influence the organization’s operational efficiency in planning, operations, and monitoring and evaluation, demonstrating statistical significance at the 0.05 level. This study also discovered that personnel at the Revenue Office in Thailand, with varying lengths of work experience, exert differing impacts on the organization’s operational efficiency. Notably, the group of personnel with over 15 years of work experience demonstrated a higher average in operational efficiency than all other groups with less than 15 years of experience, a difference that was statistically significant at the 0.05 level.

 

Keywords: internal control, operational efficiency, Revenue Department in Thailand, work experience.

Schizophrenia (SCZ) is a chronic mental disorder with a lifetime risk of approximately 1%. It is characterized by a profound disruption in cognition, behavior, and sensation with heritability estimated at up to 80%. It is a disorder with a complex etiology that involves multiple and heterogeneous genetic factors. The polygenic model of genetic susceptibility of psychiatric diseases explains that genetic variants of multiple genes determine the overall risk of disease because of their multiplicative effect. Two subunits of voltage-gated calcium channels, cacna1c and cacnb2 genes, play important roles in balancing calcium in brain cells, and their single-nucleotide polymorphisms (SNPs) have been associated differently with schizophrenia risk in different ethnicities. Two SNPs (rs1006737 & 4765913) of the cacna1c gene and a SNP (rs12257556) of the cacnb2 gene have been associated with schizophrenia. In this study, confirmed diagnosed schizophrenia patients and age-matched healthy control subjects were analyzed for the association of SNPs (rs1006737, 4765913 & rs12257556) with schizophrenia risk in Pakistani patients. Both SNPs of the cacna1c gene (rs1006737 and rs4765913) showed significant association with schizophrenia risk in this population. Moreover, two haplotypes (AT and GA) out of four for SNPs (rs1006737, rs4765913) of cacna1c further verified their significant association with the risk of schizophrenia. For cacnb2 , no significant association with the risk of schizophrenia in the SNP (rs12257556) was observed. The results of this study offer compelling evidence of a strong link between cacna1c polymorphisms (individual variant & haplotypes) and schizophrenia risk in the Pakistani population.

 

Keywords: single-nucleotide polymorphisms, rs1006737, rs4765913, rs12257556.
