ENHANCE CANONICAL IMAGE COMPUTATION FOR FINITE PERMUTATION GROUPS USING GRAPH BACKTRACKING

In this paper, we present a novel algorithm for efficiently computing canonical images of objects under the action of finite permutation groups. Our approach builds upon previous work utilizing Graph Backtracking, an extension of Jeffrey Leon's Partition Backtrack framework. By generalizing both Nauty and Steve Linton's Minimal Image algorithm, our method achieves significant improvements in computational efficiency and accuracy. We introduce a systematic exploration of the permutation group structure to guide the canonical image computation process, resulting in enhanced performance compared to existing methods. Through rigorous theoretical analysis and empirical evaluation, we demonstrate the effectiveness and scalability of our algorithm across diverse application scenarios

Ethnomedicinal plant knowledge and practice of the Oromo ethnic group in southwestern Ethiopia

An ethnomedicinal study was conducted to document the indigenous medicinal plant knowledge and use by traditional healers in southwestern Ethiopia from December 2005 to November 2006. Data were collected from 45 randomly selected traditional healers using semi-structured interviews and observations. Sixty-seven ethnomedicinal plant species used by traditional healers to manage 51 different human ailments were identified and documented. Healers' indigenous knowledge was positively correlated with their reported age but not with their educational level. High degree of consensus was observed among traditional healers in treating tumor (locally known as Tanacha), rabies (Dhukuba Seree) and insect bite (Hadhaa). The use of more than one species was significantly cited for remedy preparations. The reported abundance of the ethnomedicinal plant species varied significantly with respect to the presence of multiple uses of the reported species. Our results showed that ethnomedicinal plant species used by healers are under serious threat due to several factors, which indicates the need for urgent attention towards their conservation and sustainable utilization

Particularistic and system trust in family businesses: the role of family influence

Research on how trust develops and why it matters in family businesses is in development. Our study investigates the emergence and the evolution of trust in family business leaders. Drawing on the New Systems Theory, we also examine the impact of family influence on trust. Multiple semi‐structured interviews were performed in three Chinese family businesses. Results suggest that relationship‐based particularistic trust prevails at the start‐up stage because of the void of governance mechanisms. As businesses grow, particularistic trust gradually gives way to institution‐based system trust. Evidence further indicates high family influence catalyzes particularistic trust initially and restricts system trust subsequently

Dark energy survey year 1 results: calibration of redMaGiC redshift distributions in DES and SDSS from cross-correlations

These results determine the priors of the redshift distribution of redMaGiC galaxies, which were used for galaxy clustering measurements and as lenses for galaxy-galaxy lensing measurements in DES Y1 cosmological analyses. We empirically determine the bias in redMaGiC photometric redshift estimates using angular cross-correlations with Baryon Oscillation Spectroscopic Survey (BOSS) galaxies. For DES, we calibrate a single-parameter redshift bias in three photometric redshift bins: z is an element of [0.15, 0.3], [0.3,0.45], and [0.45,0.6]. Our best-fit results in each bin give photometric redshift biases of vertical bar Delta z vertical bar < 0.01. To further test the redMaGiC algorithm, we apply our calibration procedure to SDSS redMaGiC galaxies, where the statistical precision of the cross-correlation measurement is much higher due to a greater overlap with BOSS galaxies. For SDSS, we also find best-fit results of vertical bar Delta z vertical bar < 0.01. We compare our results to other analyses of redMaGiC photometric redshifts.481224272443FINEP - FINANCIADORA DE ESTUDOS E PROJETOSFAPERJ - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DO RIO DE JANEIROCNPQ - CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOMCTIC - MINISTÉRIO DA CIÊNCIA, TECNOLOGIA, INOVAÇÕES E COMUNICAÇÕESFINEP - FINANCIADORA DE ESTUDOS E PROJETOSFAPERJ - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DO RIO DE JANEIROCNPQ - CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOMCTIC - MINISTÉRIO DA CIÊNCIA, TECNOLOGIA, INOVAÇÕES E COMUNICAÇÕESSem informaçãoSem informaçãoSem informaçãoSem informaçãoAgências de fomento estrangeiras apoiaram essa pesquisa, mais informações acesse artig
