A Discontinuous Sturm-Liouville Operator With Indefinite Weight
Journal of Mathematics Research, 2010 In this paper, we consider an indefinite Sturm-Liouville operator with eigenparameter-dependent boundary conditions andtransmission conditions. In an appropriate space K, we define a new self-adjoint operator A such that the eigenvalues ofA coincide with those of such a problem and obtain asymptotic approximation for its eigenvalues and eigenfunctions.

Economic Anthropology, EarlyView.ABSTRACT In the Chinese kimchi industry, manufacturers employ product names, photographs, and logistical strategies to promote their kimchi's “Koreanness.” So, what makes their kimchi “Korean,” and how does its Koreanness formulate kimchi's commodity value?

A minimax formula for the principal eigenvalues of Dirichlet problems and its applications
Electronic Journal of Differential Equations, 2007 A minimax formula for the principal eigenvalue of a nonselfadjoint Dirichlet problem was established in [8,18]. In this paper we generalize this formula to the case where an indefinite weight is present.

Scalable Purification of Iron Oxide Nanoparticles for Organ Cryopreservation and Transplantation
Small, EarlyView.Scalable purification of silica‐coated iron oxide nanoparticles (sIONP) enables organ‐scale nanowarming and cryopreservation. Tangential flow filtration (TFF) offers a rapid and scalable alternative to conventional ultracentrifugation, completing purification in 2.5 h.

Principal eigenvalue for an elliptic problem with indefinite weight on cylindrical domains
Mathematical Biosciences and Engineering, 2008 This paper is concerned with an indefinite weight linear eigenvalueproblem in cylindrical domains. We investigate the minimization of the positiveprincipal eigenvalue under the constraint that the weight is bounded bya positive and a negative constant ...

Homicide, punishment and deterrence in Australia
Southern Economic Journal, EarlyView.Abstract Australian data encompassing 1910–2022, by year and state, were analyzed to estimate the effect of capital punishment on homicide rates. Our estimates showed that capital punishment had a negative and significant effect on homicides. In some specifications, the estimates implied that an execution was associated with 12.68 fewer homicides ...

, 2018 In this paper we will study the existence of solutions for the nonhomogeneous elliptic equation with variable exponent $\Delta^2_{p(x)} u=\lambda V(x) |u|^{q(x)-2} u$, in a smooth bounded domain,under Neumann boundary conditions, where $\lambda$ is a ...

Living With Chronic Rhinosinusitis: Insights From an Arts‐Based Study
World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Background Chronic rhinosinusitis (CRS) significantly reduces quality of life (QoL), but data regarding the extent of its impact is sparse. Questionnaire‐based assessments of QoL may neglect aspects of complex patient experiences. Recent studies on asthma patients and other chronic conditions have used self‐expression through artwork to better
