To evaluate the effect of potential risk factors, especially human papillomavirus type 16 (HPV-16) infection and nutritional status on the course of cervical dysplasia, we analyzed data from an intervention trial conducted from 1985 to 1990, in Birmingham, Alabama. With the use of data of four repeated evaluations of dysplasia at an interval of 2 months, specific relationships between HPV-16 in...

BACKGROUND Lung transplants, in particular, have the highest rate of infections among solid organ transplant recipients. However, there is no existing objective measure to predict the development of infections. We report the correlation between Cylex ImmuKnow (ng/mL ATP) values and various infectious syndromes in a large prospective cohort of lung transplant recipients. METHODS We followed up...

BACKGROUND Experienced ultrasonographers can rule out pneumothorax reliably. The authors hypothesized that with basic training, anesthesia residents and faculty can also reliably rule out pneumothorax when presented with an optimal ultrasound image of the chest. METHODS The study investigators created a library of 99 ultrasound video images of the chest with or without pneumothorax obtained f...

Hidden leaks from water supply networks account for 50% to 90% of total leakage losses. The presence two or more simultaneous in a section the network significantly reduces accuracy locating hidden leaks. method independent Poisson events and hypothesis stationarity, absence consequences, ordinariness are used probabilistic description problem multi-leakage networks. analytical dependence proba...

BACKGROUND Readmission of mechanically ventilated patients to an ICU within 7 d reflects not only patient safety but also the quality of care of the ICU. This study aimed to investigate the risk and related factors for readmission to an ICU within 7 d in mechanically ventilated subjects. METHODS A total of 658,452 mechanically ventilated subjects discharged from an ICU whose age was ≥ 17 y ol...

accurate and nondestructive methods to determine individual leaf areas of plants are useful tools in physiological and agronomic research. a determination of the individual leaf area (la) of such species in brassicaceae family as red cabbage (brassica oleracea var. cappitata l. f. rabra), cabbage (brassica oleracea var. cappitata l. f. alba) and broccoli (brassica oleracea var. italica l.) ...

In the present work, under some di¤erentiability conditions on the potential functions , we …rst reduce the inverse scattering problem (ISP) for the polynomial pencil of the Scroedinger equation to the corresponding ISP for the generalized matrix Scrödinger equation . Then ISP will be solved in analogy of the Marchenko method. We aim to establish an e¤ective algorithm for uniquely reconstructin...

In this paper, the problem of estimating core losses for inductive components is addressed. A novel methodology applied to estimate an inductor in a DC-DC converter time-domain. The addresses both non-linearity and dynamic behavior magnetic material non-uniformity field distribution device geometry. natively implemented using LTSpice simulation environment can be used include accurate behaviora...

‎this paper obtains the exact solutions of the wave equation as a second-order partial differential equation (pde)‎. ‎we are going to calculate polynomial and non-polynomial exact solutions by using lie point symmetry‎. ‎we demonstrate the generation of such polynomial through the medium of the group theoretical properties of the equation‎. ‎a generalized procedure for polynomial solution is pr...
