Lifespan tree of brain anatomy: diagnostic values for motor and cognitive neurodegenerative diseases [PDF]

open access: yesarXiv
The differential diagnosis of neurodegenerative diseases, characterized by overlapping symptoms, may be challenging. Brain imaging coupled with artificial intelligence has been previously proposed for diagnostic support, but most of these methods have been trained to discriminate only isolated diseases from controls.

Microstructural and Mechanical Properties of a Hard Anodic Coating Applied on an Elastically Prestrained Aluminum Substrate

open access: yesAdvanced Engineering Materials, EarlyView.
Prestraining the substrate influences coating formation process. Higher prestraining force leads to higher coating thickness and lower hardness. Increase in prestraining force enhances preliminary damage in hard anodic coating. Fatigue damage mechanisms change for hard anodized prestrained samples.

Impact of Hot Isostatic Pressing on Microstructure Evolution and Creep Performance of Powder Bed Fusion–Laser Beam Processed CM247LC

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of Hot Isostatic Pressing (HIP) temperature on the microstructure and creep performance of powder bed fusion–laser beam processed CM247LC superalloy is investigated. Grain growth and γ’ precipitate evolution are characterized following HIP at varying temperatures.

Project THANKS: A Socio-Ecological Framework For An Intervention Involving HIV Positive African American Women With Comorbidities

open access: yes, 2015
HIV-positive individuals are living longer today as a result of continuing advances in treatment but are also facing an increased risk for chronic diseases such as diabetes, and hypertension. These conditions result in a larger burden of hospitalization,

Efficient and Scalable Radiative Cooling for Photovoltaics Using Solution‐Processable and Solar‐Transparent Mesoporous Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...

Preserved cognitive functions with age are determined by domain-dependent shifts in network responsivity

open access: yesNature Communications, 2017
Cognitive abilities change with age, but why some decline and some do not is not clear. Here, the authors use data from the Cam-CAN cohort to show that distributed, multi-component brain responsivity and default-mode deactivation supports and ...
