Roadway Crash Trend Analysis with Innovative Trend Analysis and Mann-Kendall Test
, 2022 Following the national goal of crash reduction, the state of Louisiana set an ambitious goal of ‘Destination Zero Deaths’ (DZD), aiming to halve the number of fatalities and severe injuries by 2030. The goal of this study is to detect and quantify fatal and severe injury (FSI) trends in several DZD focus areas, including young drivers, alcohol ...

Homogeneity of Climate Aridity Index Trends Using Mann-Kendall Trend Test [PDF]
Journal of Korea Water Resources Association, 2014 우리나라 전국 43개 기후관측지점을 대상으로 기후 건조지수 추세의 시간적(월별, 계절별, 연별) 동질성을 분석하였다. 또한 43개 기후관측지점을 9개 지역으로 구분하여 이들 각 지역과 전체 9개 지역을 대상으로 시간적 및 지역적인 기후 건조지수 추세의 동질성 유무와 추세정도를 파악하였다. 분석을 위해 43개 기후관측지점의 월별, 계절별 그리고 연별 건조지수를 강수량과 FAO Penman-Monteith식으로 계산된 잠재증발산량으로부터 산정하였다. 또한 산정된 지수를 이용하여 Mann-Kendall 추세분석을 실시하였고, 추세분석 결과(Z scores)를 이용하여 기후 건조지수 추세의 시간적 및 지역적 동질성 분석을 실시하였다.

Cadmium and Zinc‐Doped p‐type Sb2Se3 Single Crystals and Solar Cells
Advanced Energy and Sustainability Research, EarlyView.Cd and Zn were assessed as candidate p‐type dopants in Sb2Se3 single crystals in concentrations between 1016‐1020 cm−3. Both are effective in inducing p‐type conductivity, however Cd doped crystals exhibit lower resistivity across a wider range of dopant levels.

Prognostic Utility of the Preoperative Cachexia Index in Patients Undergoing Emergency Laparotomy
Annals of Gastroenterological Surgery, EarlyView.The preoperative cachexia index, incorporating muscle mass, nutritional status, and inflammation, predicts in‐hospital and one‐year mortality in patients undergoing emergency laparotomy. This simple index may aid in risk stratification and perioperative decision‐making in high‐risk surgical patients. ABSTRACT Aim Emergency laparotomy is associated with

Annals of Gastroenterological Surgery, EarlyView.This retrospective study identified low preoperative psoas muscle volume, measured by computed tomography, as an independent predictor of postoperative complications in patients undergoing emergency surgery for strangulated small bowel obstruction. Low psoas muscle volume, particularly in older adults, was associated with cardiopulmonary and systemic ...

ANALYSIS OF PRECIPITATIONS BY NON-PARAMETRIC TESTS OF MANN-KENDALL AND KRUSKAL-WALLIS
Mercator, 2020 Resumo O objetivo principal desta pesquisa foi verificar o comportamento temporal das chuvas a longo prazo, numa localidade inserida no Semiárido brasileiro. Para isso, utilizaram-se dados mensais de precipitação secular (1911 a 2017), cedidos pelo DNOCS/SUDENE. De posse dos dados, determinaram-se as estatísticas descritivas nas escalas mensais, anuais,

Changes in wet nitrogen deposition in the United States between 1985 and 2012
Environmental Research Letters, 2014 The United States (US) is among the global hotspots of nitrogen (N) deposition and assessing the temporal trends of wet N deposition is relevant to quantify the effectiveness of existing N regulation policies and its consequent environmental effects ...

Arthritis &Rheumatology, EarlyView.Objective Cardiovascular events are major determinants of morbidity and mortality in systemic lupus erythematosus (SLE), particularly in patients with renal involvement. Although oxidative stress has been implicated in driving vascular and renal damage in SLE, the specific mechanisms remain unclear.
