Antimaximum principle for elliptic problems with weight
Electronic Journal of Differential Equations, 1999 This paper is concerned with the antimaximum principle for the linear problem with weight $-Delta u = lambda m(x) u +h(x)$, under Dirichlet or Neumann boundary conditions.

Clinical Anatomy, EarlyView.ABSTRACT The use of human donor bodies for anatomical examination in the United Kingdom is regulated by the Human Tissue Authority (England, Wales, and Northern Ireland) and His Majesty's Inspector of Anatomy for Scotland. This study aimed to assess the variability of information provided to body donors and the associated consent forms across UK ...

On solvability of an indefinite Riccati equation [PDF]
, 2013 This note concerns a class of matrix Riccati equations associated with stochastic linear-quadratic optimal control problems with indefinite state and control weighting costs. A novel sufficient condition of solvability of such equations is derived, based

On the representation of integers by quadratic forms
, 2006 Let Q be a non-singular quadratic form with integer coefficients. When Q is indefinite we provide new upper bounds for the least non-trivial integral solution to the equation Q=0. When Q is positive definite we provide improved upper bounds for the least

European Journal of Heart Failure, EarlyView.The value of uACR. CKD, chronic kidney disease; CVD, cardiovascular disease; eGFR, estimated glomerular filtration rate; uACR, urine albumin‐to‐creatinine ratio. Abstract The high disease burden and bidirectional relationship of chronic kidney disease (CKD), heart failure (HF) and other cardiovascular disease (CVD) necessitate the need for early ...

A global bifurcation result of a Neumann problem with indefinite weight
Electronic Journal of Qualitative Theory of Differential Equations, 2004 This paper is concerned with the bifurcation result of nonlinear Neumann problem \begin{equation} \left\{\begin{array}{lll} -\Delta_p u=& \lambda m(x)|u|^{p-2}u + f(\lambda,x,u)& \mbox{in} \ \Omega\\ \frac{\partial u}{\partial \nu}\hspace{0.55cm}= & 0 &

Principal eigenvalues for indefinite-weight elliptic problems in 𝑅ⁿ [PDF]
Proceedings of the American Mathematical Society, 1992 We consider the problem − Δ u = λ g u - \Delta u = \lambda gu in R n {R^n} , u → 0 u \to 0 at ∞ \infty with g g a function that changes sign.
