A Demographic Profile of Independently Incorporated Native American Foundations and Selected Funds in the United States
This report gives basic demographic information on 60 grantmaking entities grouped into three categories: 1) Native foundations that are independently incorporated; 2) 501c3 Native organizations; and 3) tribal funds. These categories capture the variety of Native controlled approaches currently at work in the field
Predicted Unusual Catalytic Activity of One-Dimensional Pt-Induced Atomic Nanowires on Ge(001) Surface
One
dimensional (1D) metal-induced nanowires on a semiconductor
surface have attracted enormous interest recently because of their
unique electronic properties and great potential in device applications
arising from the ideal 1D nature of the systems. Via ab initio modeling,
we investigate for the first time the catalytic properties of Pt-induced
nanowires (Pt-INWs) on a Ge(001) surface that have been successfully
fabricated in experiments. We show that these 1D atomic wires can
also be used as excellent catalysts for chemical reaction of CO oxidation.
A new ground-state configuration of Pt-INWs on Ge (001) that is significantly
more stable than previously reported ones is predicted. The origin
of the low reaction barrier of the catalyzed CO oxidation is thoroughly
discussed. These results pave the way for a new class of high-performance
catalysts with 1D characteristics

ObjectivesTo determine whether the age at menarche (AAM) and the age at menopause (ANM) are causally related to the development of sepsis.MethodsWe performed a two-sample Mendelian randomization (MR) analysis by utilizing summary statistics from genome-wide association study (GWAS) datasets for both the exposure and outcome variables. Single nucleotide polymorphisms (SNPs) that exhibited significant associations with AAM and ANM were chosen as instrumental variables to estimate the causal effects on sepsis. Our study employed a variety of methods, including MR-Egger regression, weighted median estimation, inverse variance weighting, a simple model, and a weighted model. Odds ratios (ORs) along with their corresponding 95% confidence intervals (CIs) were used as the primary indicators for assessing causality. Furthermore, we conducted sensitivity analyses to explore the presence of genetic heterogeneity and validate the robustness of the tools employed.ResultOur analysis revealed a significant negative causal relationship between AAM and the risk of sepsis (IVW: OR = 0.870, 95% CI = 0.793–0.955, P = 0.003). However, our Mendelian randomization (MR) analysis did not yield sufficient evidence to support a causal link between ANM and sepsis (IVW: OR = 0.987, 95% CI = 0.971–1.004, P = 0.129).ConclusionsOur findings suggest that an earlier AAM may be associated with an increased risk of sepsis. However, we did not find sufficient evidence to support a causal relationship between ANM and sepsis.</div
