The aim of our study was to examine whether pre-natal exposure to dichlorodiphenyldichloroethylene (DDE) increases the risk of lower respiratory tract infections (LRTIs) and wheeze in infants. The study is based on a birth cohort of 1,455 mother-child pairs. Maternal serum concentrations of DDE, polychlorinated biphenyls (PCBs) and hexachlorobenzene (HCB) were measured during pregnancy. Parenta...
Differential evolution (DE) is a prominent stochastic optimization technique for global optimization. After its original definition in 1995, DE frameworks have been widely researched by computer scientists and practitioners. It is acknowledged that structuring a population is an efficient way to enhance the algorithmic performance of the original, single population (panmictic) DE. However, only...
Late last month the NEW ENGLAND JOURNAL OF MEDICINE (NEJM) published a study (by David J. Hunter) comparing the levels of DDE and PCBs in the blood of two groups of women, one group with breast cancer, the other without.[1] The Hunter study failed to find a positive relationship between breast cancer and DDE or PCBs in the blood. DDE is a breakdown product of the organochlorine pesticide DDT, w...
Intestinal absorption mechanisms of young calves change rapidly during the first 24 h postpartum and subsequently effect the absorption efficiencies of a wide range of compounds. This study was conducted to determine absorption efficiencies of (p,p'-dichlorodiphenyl)dichloroethylene (DDE), 2,2',4,4',5,5'-hexachlorobiphenyl (PCB-153), and 1,2,3,4,6,7,8,9-octachlorodibenzo-p-dioxin (OCDD) when ad...
در این مقاله، نخست با تبیین نظریه تأثیر قصد بر مشروعیت عمل (dde) و شرح محدوده دقیق ادّعای آن، در ادامه ادلّه مخالفان این نظریه در قالب پنج دسته دلیل ارائه می گردد. سپس پاسخ و ادلّه طرفداران dde بیان می شود که ضمن ردّ استدلال های طرف مقابل، شواهدی برای تثبیت ادّعای خویش عرضه داشته اند. نگارنده با ارزیابی آرای دو گروه، به این جمع بندی می رسد که دلایل مخالفان dde، آن اندازه قوّت ندارد که بتواند ادّعای شه...
All-Solid-State Batteries In article number 2300172, Ju Young Kim, Yong Min Lee, and co-workers present a dry pre-lithiation strategy for the graphite/silicon-based diffusion-dependent electrodes (DDEs) by simply introducing Li metal powder in DDE. The added uniformly continuously provides ions to active materials mitigates volume change of DDE during charge/discharge cycles, leading high-perfo...
BACKGROUND Although it is known that sperm aneuploidy contributes to early pregnancy losses and congenital abnormalities, the causes are unknown and environmental contaminants are suspected. OBJECTIVES Our goal was to evaluate associations between lifetime exposure to organochlorines, specifically dichlorodiphenyldicholorethylene (p,p´-DDE) and polychlorinated biphenyls (PCBs), and sperm aneu...
OBJECTIVES To investigate the effect of prenatal exposure to polychlorinated biphenyls (PCBs) and dichlorodiphenyl-dichloroethylene (DDE) on weight, height and body mass index (BMI) in adult female offspring of the Michigan fisheater cohort examined between 1973 and 1991. METHODS 259 mothers from the Michigan fisheater cohort were studied. Prenatal exposure to PCBs and DDE was estimated by ex...
In this paper, by considering ordinary differential equation (ODE) as a special case and a starting point of delay differential equation (DDE), we will show that some typical topological methods such as continuation theorems can be applied to detect some dynamics of DDE like periodic solutions. Several problems will be presented.
This paper presents a data-driven method for constructing Koopman linear model based on the Direct Encoding (DE) formula. The prevailing methods, Dynamic Mode Decomposition (DMD) and its extensions are least squares estimates that can be shown to biased towards data densely populated. DE formula consisting of inner products nonlinear state transition function with observable functions does not ...
