BACKGROUND Both gastric bypass (GB) and duodenal switch with sleeve gastrectomy (DS) have been widely used as bariatric surgeries, and DS appears to be superior to GB. The aim of this study was to better understand the mechanisms leading to body weight loss by comparing these two procedures in experimental models of rats. METHODS Animals were subjected to GB, DS or laparotomy (controls), and ...

Assume a local simulator (LS) of a given system is available and we wish to turn it into a distributed simulator (DS). In the DS case, the LS is partitioned into segments called federates, each federate being run by a separate host. Before implementing the DS (i.e., at design-time) we wonder: will the DS execution time be shorter than LS one? In some cases the DS may run slower than the equival...

Census counts are subject to different types of nonsampling errors. One of these main errors is coverage error. Undercount and overcount are two types of coverage error. Undercount usually occurs more than the other, thus net undercount estimation is important. There are various methods for estimating the coverage error in censuses. One of these methods is dual system (DS) that usually uses dat...

We report new measurements of the branching fraction B(Ds+→ℓ+ν), where ℓ+ is either μ+ or τ+(→π+ν¯τ), based on 6.32 fb−1 electron-positron annihilation data collected by BESIII experiment at six center-of-mass energy points between 4.178 and 4.226 GeV. Simultaneously floating Ds+→μ+νμ Ds+→τ+ντ components yields B(Ds+→τ+ντ)=(5.21±0.25±0.17)×10−2, B(Ds+→μ+νμ)=(5.35±0.13±0.16)×10−3, ratio decay wi...

In this study, stability of hyaluronic acid (HA) based nanoemulsion was systematically investigated. Factors including zeta potential, pH, crosslinking agents and degree of substitution (DS) were considered to assess their roles in stability. Nanoemulsions prepared from HA-GMS with higher DS showed smaller droplet sizes. In the presence of Ca2+ as a crosslinker, size distribution was improved t...

In the paper, we present simulation results for the 32 channel DS CDMA WLAN utilising modified Walsh-Hadamard spreading sequences. The method to obtain those spreading sequences is shown. The resultant system BER as well as the distribution of errors within frames is given. The obtained results indicate that with the application of a hybrid ARQ scheme with errors and erasures decoding, the numb...

On the basis of analyzing the principle of multicarrier DS-CDMA, we propose a novel multiband complex wavelet based multicarrier DS-CDMA system in this paper by using the optimized multiband complex wavelet as multicarrier basis function. The system bit error rate (BER) performance is investigated over Nakagamim fading channel. Without any cyclic prefix (CP), the proposed system can avoid the d...

Although it is well established that the renal endothelin (ET-1) system plays an important role in regulating sodium excretion and blood pressure through activation of renal medullary ET(B) receptors, the role of this system in Dahl salt-sensitive (DS) hypertension is unclear. The purpose of this study was to determine whether the DS rat has abnormalities in the renal medullary endothelin syste...

We have investigated the thermal evolution of the structure and the dynamics of poly~vinyl chloride! ~PVC! in a wide temperature range. Corroborating earlier findings, small angle neutron scattering revealed the presence of structural heterogeneities. On the other hand, the single chain form factor corresponds to that of Gaussian chains. Gradually with increasing temperature the system becomes ...
