Critical Metrics of the Scalar Curvature Functional

open access: yesTokyo Journal of Mathematics, 1999
Consider a compact connected \(n\)-manifold \(M\) and an integer \(p\in\mathbb{N}\). Let \({\mathcal M}(N)\) denote the space of Riemannian metrics on \(M\). In her paper, the author studies the critical metrics of the functional \({\mathcal S}^p:{\mathcal M}(M)\to \mathbb{R}\), \(g\mapsto (\int_M R^p_gv_g) (\int_M v_g)^{-{n-2p\over n}}\), where \(R_g\)

Critical Metrics for the Determinant of the Laplacian in Odd Dimensions [PDF]

open access: yesThe Annals of Mathematics, 2001
Let M be a closed compact n-dimensional manifold with n odd. We calculate the first and second variations of the zeta-regularized determinants det^\primeΛand det L as the metric on M varies, where Δdenotes the Laplacian on functions and L denotes the conformal Laplacian. We see that the behavior of these functionals denotes the conformal Laplacian.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Quantification of three-dimensional cell-mediated collagen remodeling using graph theory. [PDF]

open access: yesPLoS ONE, 2010
Cell cooperation is a critical event during tissue development. We present the first precise metrics to quantify the interaction between mesenchymal stem cells (MSCs) and extra cellular matrix (ECM).

Metric Criticality Identification for Cloud Microservices

open access: yesCoRR
Modern cloud-native applications built on microservice architectures present unprecedented challenges for system monitoring and alerting. Site Reliability Engineers (SREs) face the daunting challenge of defining effective monitoring strategies across multitude of metrics to ensure system reliability, a task that traditionally requires extensive manual ...

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Critical Riemannian metrics [PDF]

open access: yes, 1990
Let $(M,g)$ be a compact oriented n-dimensional smooth Riemannian manifold. Consider the following quadratic Riemannian functional$$SR(g) = \int\sb{M}\ \vert R\sb{ijkl}(g)\vert \sp{2}d\mu$$which is homogeneous of degree ${n\over2}-2,$ where $R\sb{ijkl ...
