Incident Lung Cancer and Mortality: Data From Health ABC Using Periodontal Status and Tooth Loss

Oral Diseases, EarlyView.
ABSTRACT Aim To evaluate whether periodontal parameters and tooth loss are associated with lung cancer incidence and mortality among older adults. Materials and Methods Data are from the Health, Aging and Body Composition (Health ABC) study, which included 1136 older adults who received a periodontal examination and were followed for up to 16 years ...

FWM-based wavelength conversion of 40 Gbaud PSK signals in a silicon germanium waveguide.

Optics Express, 2013
We demonstrate four wave mixing (FWM) based wavelength conversion of 40 Gbaud differential phase shift keyed (DPSK) and quadrature phase shift keyed (QPSK) signals in a 2.5 cm long silicon germanium waveguide.

The Impact and Reliability of Tissue Segmentation on In Vivo Magnetic Resonance Spectroscopy Metabolite Quantification

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 516-529, August 2026.
ABSTRACT Purpose Quantification of metabolite concentrations using MRS requires tissue‐dependent signal corrections. Accurate estimation of voxel tissue composition is therefore essential. Commonly used brain tissue segmentation tools differ in their algorithms and implementation, potentially introducing variability in MRS‐derived concentration ...

Biomimicry of the Hawk Moth, Manduca sexta (L.), Produces an Improved Flapping-Wing Mechanism

Biomimetics, 2020
Flapping-wing micro air vehicles (FWMAVs) that mimic the flight capabilities of insects have been sought for decades. Core to the vehicle’s flight capabilities is the mechanism that drives the wings to produce thrust and lift.
