A High-Order Imaging Algorithm for High-Resolution Space-Borne SAR Based on a Modified Equivalent Squint Range Model

Two challenges have been faced in signal processing of ultrahigh-resolution spaceborne synthetic aperture radar (SAR). The first challenge is constructing a precise range model, and the second one is to develop an efficient imaging algorithm since traditional algorithms fail to process ultrahigh-resolution spaceborne SAR data effectively. In this paper, a novel high-order imaging algorithm for high-resolution spaceborne SAR is presented. First, a modified equivalent squint range model (MESRM) is developed by introducing equivalent radar acceleration into the equivalent squint range model, and it is more suitable for high-resolution spaceborne SAR. The signal model based on the MESRM is also presented. Second, a novel high-order imaging algorithm is derived. The insufficient pulse-repetition frequency problem is solved by an improved subaperture method, and accurate focusing is achieved through an extended hybrid correlation algorithm. Simulations are performed to validate the presented algorithm

Dollar Estimates of Feral Hog Damage to Agriculture in Louisiana (Research Information Sheet #113)

A study of feral hog activity and damage in Louisiana. Data were gathered from Louisiana farmers. The study results show that feral hogs caused at least $30 million in damage to crops on Louisiana farms in 2013.

Obesity and Physical Activity Variance by Income and Ethnicity in Kansas City

Purpose: Although obesity and physical activity prevalence systematically vary by income and ethnicity, it is unclear how well census data represent actual conditions. Using data from the Kansas City Built Environment and Health Study, we examined whether differences in measured obesity prevalence and self-reported physical activity would systematically vary by both census block group median income and percent ethnic minority and self-reported income and ethnicity. Methods: Participants included 586 adults; average age 45±14.7. Most participants were female (69.8%), married (51.5%), had some college or more (72.7%) and had incomes ≤$60,000 (54.6%). Households were solicited from 21 census block groups, stratified by household income and percent ethnic minority across the Kansas City Metropolitan area. After obtaining informed consent, trained data collectors conducted 60-minute interviews. Physical activity was measured with the International Physical Activity Questionnaire. Height was measured with a portable stadiometer and weight and percent body fat (%BF) percentages were measured using a Tanita scale. Results: Using calculated BMI data, 33.3% were obese; 55.8% were obese when using %BF. Comparison by census block group showed significantly lower obesity rates (BMI) for the highest income tertile (p=.01) and the lower ethnic minority tertile (p=.009 BMI; p\u3c.001 %BF). Self-reported ethnicity data showed significantly higher obesity rates for both African Americans and American Indians (p=.001 BMI; p\u3c.001 %BF). Overall, physical activity levels were low, with only 19.1% (n=112) meeting walking, 9.4% (n=55) meeting moderate (both 150+minutes/week), and 24.7% (n=145) meeting vigorous recommendations (75+minutes/week). Both census and self-reported income were positively correlated with meeting walking recommendations (p\u3c.01) and meeting vigorous activity recommendations (p\u3c.05 and p\u3c.05, respectively). Meeting vigorous activity recommendations was significantly more likely for those in the lower ethnic minority tertile (p=.04). Conclusions: We found systematic variation across income and ethnicity for both obesity and physical activity, with worse rates for lower income individuals, Blacks and American Indians. BMI may have underestimated obesity prevalence. Future research should determine related environmental correlates

Fracture behaviour of notched round bars made of PMMA subjected to torsion at -60 °C

This paper presents seventy new experimental results from PMMA notched specimens tested under torsion at 60 C. The notch root radius ranges from 0.025 to 7.0 mm. At this temperature the non-linear effects previously observed on specimens of the same material tested at room temperature strongly reduce. The averaged value of the strain energy density over a control volume is used to assess the critical loads to failure. The radius of the control volume and the critical strain energy density are evaluated a priori by using in combination the mode III critical stress intensity factor from cracked-like specimens and the critical stress to failure detected from semicircular notches with a large notch root radiu

Design and baseline characteristics of the finerenone in reducing cardiovascular mortality and morbidity in diabetic kidney disease trial

Background: Among people with diabetes, those with kidney disease have exceptionally high rates of cardiovascular (CV) morbidity and mortality and progression of their underlying kidney disease. Finerenone is a novel, nonsteroidal, selective mineralocorticoid receptor antagonist that has shown to reduce albuminuria in type 2 diabetes (T2D) patients with chronic kidney disease (CKD) while revealing only a low risk of hyperkalemia. However, the effect of finerenone on CV and renal outcomes has not yet been investigated in long-term trials. Patients and Methods: The Finerenone in Reducing CV Mortality and Morbidity in Diabetic Kidney Disease (FIGARO-DKD) trial aims to assess the efficacy and safety of finerenone compared to placebo at reducing clinically important CV and renal outcomes in T2D patients with CKD. FIGARO-DKD is a randomized, double-blind, placebo-controlled, parallel-group, event-driven trial running in 47 countries with an expected duration of approximately 6 years. FIGARO-DKD randomized 7,437 patients with an estimated glomerular filtration rate >= 25 mL/min/1.73 m(2) and albuminuria (urinary albumin-to-creatinine ratio >= 30 to <= 5,000 mg/g). The study has at least 90% power to detect a 20% reduction in the risk of the primary outcome (overall two-sided significance level alpha = 0.05), the composite of time to first occurrence of CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure. Conclusions: FIGARO-DKD will determine whether an optimally treated cohort of T2D patients with CKD at high risk of CV and renal events will experience cardiorenal benefits with the addition of finerenone to their treatment regimen.
