The high facioselectivity in the epoxidation of 4-deoxypentenosides (4-DPs) by dimethyldioxirane (DMDO) correlates with a stereoelectronic bias in the 4-DPs' ground-state conformations, as elucidated by polarized-pi frontier molecular orbital (PPFMO) analysis.

GOALS We designed this study to evaluate the efficacy of spleen salvage during distal pancreatectomy for patients with benign and borderline malignant tumors. BACKGROUND Despite the emphasis on its role, the spleen has commonly been removed in distal pancreatectomy. STUDY From January 2005 to July 2009, 82 patients underwent distal pancreatectomy with splenectomy (DPS) and 78 patients under...

This paper deals with the complexity of the decomposition of a digital surface into digital plane segments (DPS for short). We prove that the decision problem (does there exist a decomposition with less than k DPS ?) is NP-complete, and thus that the optimisation problem (finding the minimal number of DPS) is NP-hard. The proof is based on a polynomial reduction of any instance of the well-know...

is sentence has two meanings that depend on how she is semantically interpreted. On one meaning, she refers to the same individual that Sally does. On this interpretation, we say that she is “coreferent” with Sally. On the other interpretation, she refers to some female individual that isn’t Sally. On this interpretation we say that she and Sally are “disjoint in reference.” One way of expressi...

Low power has played an increasingly important role for embedded systems. To save power, lowering voltage and frequency is very straightforward and effective; therefore dynamic voltage scaling (DVS) has become a prevalent low-power technique. However, DVS makes no effect on power saving when the voltage reaches a lower bound. Fortunately, a technique called dynamic pipeline scaling (DPS) can ov...

This work introduces a proficient method to build a newly proposed code, named diagonal permutation shifting (DPS) code for the spectral-amplitude-coding (SAC) optical code-division multiple-access (OCDMA) system. The DPS code is derived and constructed from well-known prime codes and certain matrix operations. This proposed code possesses numerous properties such as the cross-correlation (CC) ...

This paper investigates the control problem of distributed parameter systems (DPS) with time-varying delay by employing mobile actuator-sensor networks. It is assumed that each agent in the networks has a sensor device which can measure spatial state, and an actuator device that can dispense control signals to spatially distributed process and can communicate with its neighbors. To better contr...

The chemokine IP-10 (CXCL10) is a candidate marker for hepatitis C virus (HCV) fibrosis monitoring. The aim of this proof-of-concept study is to assess if IP-10 measurements from dried plasma spots (DPS) are accurate in HCV-infected patients with either minimal or significant fibrosis. We measured IP-10 levels in plasma and DPS of 21 HCV-infected patients with cirrhosis and 19 patients with no/...

In this paper, we model the end-to-end QoS provisioning mechanisms in the WLAN and 3GPP interworking network. For the end-to-end QoS guaranteed service, we model the control plane and user plane considering the WLAN and 3GPP interworking network. And we propose the QoS parameter/class mapping and DPS packet scheduler. By the simulation results, DPS can provide the low end-to-end delay of voice ...

Abstract Paper reports the main results of a systematic study on longitudinal train dynamics (LTD) long freight trains, equipped with radio communication. The simulation have been used to prepare an experimental test campaign Distributed Power System (DPS) technology. simulations refer up/down and level track they compare LTD trains without DPS, for different operations link conditions. DPS tec...
