Astronomy at sub-millimeter wavelengths [PDF]

The first flight test of a gondola containing a Newtonian telescope with a 16 in. primary mirror is described. Bolometer tests were conducted along with gondola design studies, and changes were made in the mechanical system as a result.

Early evolutionary history of the seed

Biological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Dust in the 55 Cancri planetary system

, 2000
The presence of debris disks around $\sim$ 1-Gyr-old main sequence stars suggests that an appreciable amount of dust may persist even in mature planetary systems.

Quantification of Palmar and Digital Epidermal Thickness and Sweat Duct Density

Clinical Anatomy, EarlyView.
ABSTRACT Palmar digital skin, with its high density of epidermal sweat glands and unique stratum corneum, derives its autonomic innervation from peripheral nerves. Understanding the changes to these structures could serve as objective proxy markers following peripheral nerve injury and interventions to promote regeneration.

Talin1 Adhesion Morphology and Colocalization With Tensin3 Are Largely Unaffected by Polyacrylamide Substrate Stiffness

Cytoskeleton, EarlyView.
ABSTRACT Cells sense the stiffness of their extracellular matrix (ECM) and adapt their behavior accordingly. We investigated how ECM stiffness affects the spatial organization of talin1, a key mechanosensitive focal adhesion protein. Using polyacrylamide (PA) hydrogels with tunable stiffnesses (0.2–188 kPa), we analyzed cell morphology, migration ...

Constraints on the Physical Origin of Large Cavities in Transition Disks from Multiwavelength Dust Continuum Emission

The Astrophysical Journal
The physical origin of the large cavities observed in transition disks is to date still unclear. Different physical mechanisms (e.g., a companion, dead zones, enhanced grain growth) produce disk cavities of different depth, and the expected spatial ...

Bioinspired Flexible and Stretchable Coil Structure from Ti3C2Tx MXene/AgNPs‐Functionalized Piezoelectric Nanofibers for Enhanced Energy Harvesting

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Ti3C2Tx MXene and Ag nanoparticles are embedded into piezoelectric nanofibers to form a stretchable, self‐powered coil that converts mechanical deformation into electrical energy. The device enables controllable power output during stretching and release while maintaining a compact and lightweight architecture, making it suitable for miniaturized ...
