In this paper, we introduce a new geometric description of the manifolds matrices fixed rank. The starting point is Grassmann manifold Gr(Rk) linear subspaces dimension r<k in Rk, which avoids use equivalence classes. set equipped with an atlas, provides it structure analytic modeled on R(k?r)×r. Then, define atlas for Mr(Rk×r) full rank and prove that resulting principal bundle base typical...

A submanifold Σ ⊂ Rn × Rn is called Lagrangian if ω|Σ = 0. In this paper, we study a boundary value problem for minimal Lagrangian graphs in Rn×Rn. To that end, we fix two domains Ω, Ω̃ ⊂ Rn with smooth boundary. For each diffeomorphism f : Ω → Ω̃, we consider its graph Σ = {(x, f(x)) : x ∈ Ω} ⊂ Rn × Rn. We consider the problem of finding a diffeomorphism f : Ω → Ω̃ such that Σ is Lagrangian and h...

Approximately 60% of registered nurses (RNs) still enter practice with an associate’s degree or diploma in nursing (ADN). Due to recommendations to change entry level to practice to the bachelor’s degree in nursing (BSN), there are now more than 700 RN to BSN programs in the United States. The purpose of this qualitative systematic review was to understand more about what occurs when an RN retu...

Immature bowel and bladder control and large heads are inevitable contributory risk factors specific to children. Concomitant pain and altered appearance are physical and emotional burdens for patients and families already experiencing stress associated with hospitalization i...

In this paper we establish a discrete Calderón’s identity which converges in both Lq(Rn+m) (1 < q <∞) and Hardy space H(R ×Rm) (0 <p ≤ 1). Based on this identity, we derive a new atomic decomposition into (p, q)-atoms (1 < q <∞) on H(R × R) for 0 < p ≤ 1. As an application, we prove that an operator T , which is bounded on Lq(Rn+m) for some 1 < q <∞, is bounded from Hp(Rn×Rm) to Lp(Rn+m) if and...

We present a construction of anisotropic multiresolution and anisotropic wavelet frames based on multilevel ellipsoid covers (dilations) of R. The wavelets we construct are C∞ functions, can have any prescribed number of vanishing moments and fast decay with respect to the anisotropic quasi-distance induced by the cover. The dual wavelets are also C∞, with the same number of vanishing moments, ...

Introduction In June 2002, the Canadian Nurses Association (CNA) released a revised study projecting a shortage of 78,000 nurses in Canada by 2011 (Ryten 2002). This projected nursing shortage, along with the increasing average age of nurses, led The Ottawa Hospital to actively plan and strategize the sourcing of Registered Nurse (RN) positions. Annual workforce planning is followed by the deve...

Let Rn be the n-dimensional real Euclidean space, x = (x1, x2, . . . , xn) ∈ Rn be a generic vector, where the superscript T means transpose. Let x, y ∈ Rn, we denote by yTx the Euclidean scalar product, by ‖x‖ = (xTx)1/2 the Euclidean norm and by the symbols x < y and x ≤ y, x, y ∈ Rn the componentwise inequalities, that is: xi < yi, xi ≤ yi, i = 1, 2, . . . , n. Let us denote by Uδ(x̂) the ope...

Abnormal increases in radon ((222)Rn, half-life = 3.82 days) activity have occasionally been observed in underground environments before major earthquakes. However, (222)Rn alone could not be used to forecast earthquakes since it can also be increased due to diffusive inputs over its lifetime. Here, we show that a very short-lived isotope, thoron ((220)Rn, half-life = 55.6 s; mean life = 80 s),...
