Aging and the Spectral Properties of Brain Hemodynamics

open access: yesAdvanced Science, EarlyView.
As the brain ages, its metabolic demands decline—but not uniformly. Here, spectral slope flattening of resting‐state fMRI signals is proposed as a potential biomarker of pathologic brain aging. A subset of older adults diverges from youthful spectral and metabolic patterns, with changes linked to frontal white matter pathology and regional loss of ...

The Euclidean distance degree of smooth complex projective varieties

open access: yes, 2017
We obtain several formulas for the Euclidean distance degree (ED degree) of an arbitrary nonsingular variety in projective space: in terms of Chern and Segre classes, Milnor classes, Chern-Schwartz-MacPherson classes, and an extremely simple formula ...

Bio‐Inspired Strategy for Radiation‐Based Thermal Management and Utilization

open access: yesAdvanced Science, EarlyView.
Biological organisms have evolved remarkable strategies to manage and exploit thermal radiation. This review explores bio‐inspired systems that mimic these adaptations—such as radiative cooling, thermal regulation, thermal insulation, water harvesting, infrared camouflage, and infrared detection—and highlights their application in thermal management ...

Astrocytic expression of the chaperone DNAJB6 results in non-cell autonomous protection in Huntington’s disease

open access: yesNeurobiology of Disease, 2019
Several neurodegenerative diseases like Huntington's, a polyglutamine (PolyQ) disease, are initiated by protein aggregation in neurons. Furthermore, these diseases are also associated with a multitude of responses in non-neuronal cells in the brain, in ...

Sparse Nanocrystals Enable Ultra‐Low Coercivity and Remarkable Mechanical Robustness in High‐Entropy Amorphous Alloy

open access: yesAdvanced Science, EarlyView.
An order modulation strategy is introduced to overcome trade‐off between mechanical and magnetic properties by constructing an amorphous‐nanocrystalline transitional structure in a ferromagnetic HEA system. This enable the resultant alloys to combine an ultra‐low coercivity of 0.3 A m−1 with a remarkable mechanical toughness, thereby achieving a ...

Diversity of ants (Hymenoptera: Formicidae) in two rubber plantations in Songkhla Province, Southern Thailand [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2011
Ants play important roles in tropical rainforest ecosystems. In southern Thailand, many such areas have been extensivelylogged and replaced by rubber plantations.
