OBJECTIVE To test the hypothesis that the blood antithrombin (AT) activity is correlated with the plasma aldosterone concentration (PAC), the plasma renin activity (PRA), and/or the PAC-to-PRA ratio during the late stage of pregnancy. METHODS The AT activity, PAC, and PRA were determined within 7 days prior to delivery in 47 women, consisting of 30 normotensive and 6 hypertensive women with s...

The protection of anaerobes in Port-A-Cul (PAC) transport system (Bioquest, Div. of Becton, Dickinson &Co., Cockeysville, Md.) tubes and vials was studied. Ten species of obligately anaerobic bacteria commonly isolated from clinical specimens were used to prepare simulated swab and fluid specimens in high and low concentrations. Samples in PAC tubes and vials were held for 2, 24, and 48 h at am...

Polarization-adjusted convolutional (PAC) codes have better error-correcting performance than polar mostly because of the improved weight distribution brought by pre-transformation. In this paper, we propose parity check PAC (PC-PAC) to further improve codes. The design principle is establish functions between bits with distinct row weights, such that information lower reliability are re-protec...

BACKGROUND Detecting paroxysmal atrial fibrillation (PAF) in patients with cerebral ischemia is challenging. Frequent premature atrial complexes (PAC/h) and the longest supraventricular run on 24-h-Holter (SV-run(24 h)), summarised as excessive supraventricular ectopic activity (ESVEA), may help selecting patients for extended ECG-monitoring, especially in combination with echocardiographic mar...

We study PAC learning in the presence of strategic manipulation, where data points may modify their features certain predefined ways order to receive a better outcome. show that vanilla ERM principle fails achieve any nontrivial guarantee this context. Instead, we propose an incentive-aware version which has asymptotically optimal sample complexity. then focus our attention on incentive-compati...

Hemodynamicg, myocardial function, and regional myocardial blood flow (MBF) were measured during acute right ventricular (RV) pressure overload created by inflation of a previously implanted cuff to constrict the pulmonary artery trunk (PAC) in seven closed-chest, anesthetized calves during normoxia (Pad: 90-110 mm Hg) and hypoxia (PaOj ~ 40 mm Hg). MBF was determined by the microsphere method....

Today's market of Power Amplifiers (PAs) offers both PAs stand-alone and PA modules (PA plus PA Controller, PAC, integrated in the same module). PA modules do not require an on-chip PAC but simply an Automatic Power Control (APC) able to shape the transmission (TX) burst for the PAC within the PA module. In order to maximize the flexibility of the on-chip PA's control system, the design of prog...

Batch tests were conducted using four groundwater samples high levels of total hardness such as 600.17, 800.42, 1088.85 and 1278.38 mg/L as CaCO3, so as water is not suitable for several industries. The work aimed to evaluate the feasibility of using powdered pseudoactivated carbon (PAC) prepared from wheat husk for the removal of water hardness and also to study of impact of sodium dodecyl sul...

The method of the poly A-linked colorimetric reverse transcriptase assay (PAC-RTA) was developed and evaluated for the measurement of Mg(2+)-dependent reverse transcriptase (RT) activity of feline immunodeficiency virus (FIV). PAC-RTA was first evaluated for the detection of RT activity in the culture supernatant of FIV Petaluma strain. The detection limit of RT activity by PAC-RTA was about 10...
