Frailty and Cardiovascular Events as Determined by Body Composition: A Systematic Review

open access: yesChronic Diseases and Translational Medicine, EarlyView.
Frailty phenotypes and risk of cardiovascular disease. Sarcopenic obese phenotype is associated with increased prevalence of cardiovascular risk factors and progression of metabolic syndrome, leading to cardiovascular events and cardiovascular mortality, while the Anorexic malnourished phenotype is associated with reduced prevalence of cardiovascular ...

Evolution of a geometric constant along the Ricci flow

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we establish the first variation formula of the lowest constant λ a b ( g ) $\lambda_{a}^{b}(g)$ along the Ricci flow and the normalized Ricci flow, such that to the following nonlinear equation there exist positive solutions: − Δ u + a u ...

Parabolic Frequency on Ricci Flows

open access: yesInternational Mathematics Research Notices, 2022
AbstractThis paper defines a parabolic frequency for solutions of the heat equation on a Ricci flow and proves its monotonicity along the flow. Frequency monotonicity is known to have many useful consequences; here it is shown to provide a simple proof of backwards uniqueness.

Building a Robust Investigator‐Initiated Platform: The I‐CARE Experience

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Investigator‐initiated studies that include information collected by patients are rising, but limited data is available on patient and investigator experience in this setting. The I‐CARE cohort included patients with inflammatory bowel disease (IBD) monthly collecting clinical information in 15 countries for up to 6 years.

Hurdles to overcome to achieve biostimulant‐driven, low chemical input crop production

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Crop production requires considerable chemical inputs that result in significant greenhouse gas emissions and other environmental costs. Biostimulants are natural agents, such as microorganisms or seaweed, applied to plants and soil to stimulate plant growth and reduce chemical inputs. Biostimulant use is rapidly increasing globally, but hurdles remain,

A design tool for globally developable discrete architectural surfaces using Ricci flow

open access: yesJapan Architectural Review, 2023
This paper presents an approach for the design of discrete architectural surfaces that are globally developable; that is, having zero Gaussian curvature at every interior node.
