Let Tf be a circle homeomorphism with two break points ab, cb and irrational rotation number ̺f . Suppose that the derivative Df of its lift f is absolutely continuous on every connected interval of the set S\{ab, cb}, that DlogDf ∈ L 1 and the product of the jump ratios of Df at the break points is nontrivial, i.e. Df−(ab) Df+(ab) Df − (cb) Df+(cb) 6= 1. We prove that the unique Tf invariant pr...

BACKGROUND Dengue fever (DF) has been emerging in Hanoi over the last decade. Both DF epidemiology and climate in Hanoi are strongly seasonal. This study aims at characterizing the seasonality of DF in Hanoi and its links to climatic variables as DF incidence increases from year to year. METHODS Clinical suspected cases of DF from the 14 central districts of Hanoi were obtained from the Minis...

AIM There is scarce information concerning the pharmacodynamic behavior of topical substances used in the physiotherapy setting. The aim of the present study was to estimate the formation and emptying of the diclofenac (DF) skin reservoir after passive, semiocclusive, and electrically assisted applications of DF. SUBJECTS AND METHODS Five different groups of healthy volunteers (ntotal=60, 23 ...

This paper investigates the impact of chip duty factor (DF) in DS-UWB system with Rake receiver over AWGN and UWB indoor multipath environment corresponding to system parameters such as spreading bandwidth and chip length. Manipulating DF in DS-UWB system offers several advantages over multipath channel and thus, capable of improving system performance for better quality of communication. Altho...

OBJECTIVE To explore the associations between the monthly number of dengue fever(DF) cases and possible risk factors in Guangzhou, a subtropical city of China. METHODS The monthly number of DF cases, Breteau Index (BI), and meteorological measures during 2006-2014 recorded in Guangzhou, China, were assessed. A negative binomial regression model was used to evaluate the relationships between B...

We investigate the use of direct-Fourier (DF) image reconstruction in computerized tomog-raphy and synthetic aperture radar (SAR). One of our aims is to determine why the convolution-backprojection (CBP) method is favored over DF methods in tomography, while DF methods are virtually always used in SAR. We show that the CBP algorithm is equivalent to DF reconstruction using a Jacobian-weighted 2...

INTRODUCTION Diabetic foot (DF) is a serious complication of diabetes mellitus (DM) that occurs due to neuropathy or atherosclerosis of the lower limbs. Omentin (encoded by the ITLN1 gene) has been implicated as a protective factor in vascular complications of diabetes, likely due to its endothelial vasodilator activity and its anti‑inflammatory actions. However, susceptibility to DF with respe...
