recognized as a reliable tool for assessing the hypothalamus-pituitary-adrenal (hpa) axis, measurement of salivary cortisol plays an important role in both the clinical and research settings. to establish a normative data, which forms the basis for the usage of this valuable parameter, we gathered 8:00 h saliva samples from 94 healthy individuals aged 6-14 years. cortisol levels were measured b...

background and purpose: absence from work, quitting job and turnover of nursing staff put a great burden on any health care system in terms of hiring, training and maintaining nurses. studies suggest that those with higher job satisfaction are less likely to state being sick and indicate that there is a relationship between the nurses’ job satisfaction and their tendency to quit or ask for a tu...

We consider a one-dimensional translation invariant point process of density one with uniformly bounded variance of the number NI of particles in any interval I . Despite this suppression of fluctuations we obtain a large deviation principle with rate function F(ρ) ' −L log Prob(ρ) for observing a macroscopic density profile ρ(x), x ∈ [0, 1], corresponding to the coarse-grained and rescaled den...

The system Q undergoes a completely positive trace-preserving transformation or quantum operation E and R is assumed to be isolated and its state remains the same. This quantum operation is also represented by IR ⊗ E , where IR is the identity superoperator on R. We add subscript ‘1’ to denote the state of the system (joint or otherwise) after this quantum operation. So the state of the joint s...

We give parallel constructions of an invariant R(W,ρ), based on the classical Rogers dilogarithm, and of quantum hyperbolic invariants (QHI), based on the Faddeev-Kashaev quantum dilogarithms, for flat PSL(2,C)-bundles ρ over closed oriented 3-manifolds W . All these invariants are explicitely computed as a sum or state sums over the same hyperbolic ideal tetrahedra of the idealization of any f...

OBJECTIVES To investigate the association between self-reported low back pain (LBP) and lower limb disability as well as the association between neck pain and upper limb disability. METHODS A hundred twenty-six participants registered as a healthcare staff member were included in this cross-sectional study. The presence of neck and LBP were determined using the Nordic Musculoskeletal Question...

Let L ≥ 1, > 0 be real numbers, (M,d) be a finite metric space and (N, ρ) be a metric space (Rudin 1976). The metric space (M,d) is said to be Lbilipschitz embeddable into (N, ρ) if there is an injective function f :M → N with 1/L · d(x, y) ≤ ρ(f(x), f(y)) ≤ L · d(x, y) for all x, y ∈ N (Farb & Mosher 1999, David & Semmes 2000, Croom 2002). In this paper, we also say that (M,d) is -far from bei...

We study the Spitzer Infrared Array Camera (IRAC) mid-infrared (rest-frame optical) fluxes of 14 newly WFC3/ IR-detected z ∼ 7 z850-dropout galaxies and 5z ∼ 8Y105-dropout galaxies. The WFC3/IR depth and spatial resolution allow accurate removal of contaminating foreground light, enabling reliable flux measurements at 3.6μm and 4.5μm. None of the galaxies are detected to [3.6] ≈ 26.9 (AB, 2σ ),...

In this paper, we give some new generalized convexities with the tool–right upper-Diniderivative which is an extension of directional derivative. Next, we establish not only Karush-KuhnTucker necessary but also sufficient optimality conditions for mathematical programming involving new generalized convex functions. In the end, weak, strong and converse duality results are proved to relate weak ...
