Given a k-dimensional subspace M ⊆ R and a full rank integer lattice L ⊆ R, the subspace avoiding problem SAP, defined by Blömer and Naewe [BN07], is to find a shortest vector in L\M . Treating k as a parameter (in the sense of parameterized complexity), we obtain new parameterized approximation and exact algorithms for SAP based on the AKS sieving technique [AKS01]. – Our first result is a ran...

OBJECTIVES Emergency department (ED) bedside echocardiography may offer useful information on cardiac function and volume status. The authors evaluated the accuracy of emergency physician (EP) performance of echocardiography in the assessment of left ventricular ejection fraction (LVEF) and central venous pressure (CVP). METHODS The authors conducted a cross-sectional observational study at a...

Changes in intra-abdominal pressure during bowel tumor surgery have not been documented. The purpose of the present study was to analyze changes in intra-abdominal pressure (IAP), central venous pressure (CVP) and iliac venous pressure (IVP) in patients undergoing laparotomy due to large tumor of the bowel. Twenty-one adult patients undergoing elective abdominal surgery were examined. Intra-abd...

In this work we consider the closest vector problem (CVP) —a problem also known as maximum-likelihood decoding— in the tensor of two root lattices of type A (Am⊗An), as well as in their duals (Am⊗An). This problem is mainly motivated by lattice based cryptography, where the cyclotomic rings Z[ζc] (resp. its co-different Z[ζc]) play a central role, and turn out to be isomorphic as lattices to te...

It has been shown (Cambillau, C., and Claverie, J. M. (2000) J. Biol. Chem. 275, 32383-32386) that a large difference between the proportions of charged versus polar (non-charged) amino acids (CvP-bias) was an adequate, if empirical, signature of the proteome of hyperthermophilic organisms (T(growth) >80 degrees C). Since that study, the number of available microbial genomes has more than doubl...

Plasma volume is reduced by 10-20% within 24-48 h of exposure to simulated or actual microgravity. The clinical importance of microgravity induced hypovolemia is manifested by its relationship with orthostatic intolerance and reduced maximal oxygen uptake (VO2max) after return to one gravity (1G). Since there is no evidence to suggest that plasma volume reduction during microgravity is associat...

This paper introduces a new approach to Large-Eddy Simulation (LES) where subgrid-scale (SGS) dissipation is applied proportionally to the degree of local spectral broadening, hence mitigated or deactivated in regions dominated by large-scale and/or laminar vortical motion. The proposed coherentvorticity preserving (CvP) LES methodology is based on the evaluation of the ratio of the test-filter...

INTRODUCTION The early detection of critically ill patients together with the rapid initiation of effective treatment in emergency departments(ED) increase the survival rates. AIM This study investigated whether a correlation exists between haemodynamic parameters of critically ill patients and the diameter of the inferior vena cava (IVC). MATERIALS AND METHODS A cross-sectional study was p...

BACKGROUND A common problem in cardiac surgery patients is decreased central venous pressure (CVP) and systemic blood pressure during transfer from operation room to intensive care unit (ICU). Since these reductions may lead to dangerous complications, this study aimed to evaluate the effects of vasopressors and isotonic fluids on hemodynamic status of cardiac surgery patients during their tran...

Background Patients with complex congenital heart disease increasingly undergo noncardiac surgeries because of advancements in surgical techniques and medical management. In Fontan circulation, maintaining an adequate transpulmonary gradient is essential for preserving both pulmonary blood flow and cardiac output. However, intraoperative circulatory monitoring of Fontan patients has not been es...
