Reflex vasodilation is attenuated in aged skin during hyperthermia. We used laser-Doppler imaging (LDI) to test the hypothesis that the magnitude of conductance and the spatial distribution of vasodilation are altered with aging. LDI of forearm skin was compared in 12 young (19- to 29-yr-old) and 12 older (64- to 75-yr-old) men during supine passive heating. Additionally, iontophoresis of brety...

Cell membrane-derived nanoparticles are becoming more attractive because of their ability to mimic many features of their source cells. This study reports on a biomimetic delivery platform based on human cytotoxic T-lymphocyte membranes. In this system, the surface of poly-lactic-co-glycolic acid nanoparticles was camouflaged using T-lymphocyte membranes, and local low-dose irradiation (LDI) wa...

Currently, desertification is a major problem in the western desert of Iraq. The harsh nature, remoteness, and size make it difficult expensive to monitor mitigate desertification. Therefore, this study proposed comprehensive cost-effective method, via integration geographic information systems (GISs) remote sensing (RS) techniques estimate potential risk desertification, identify most vulnerab...

We created different TiO₂-based coatings on silicon nanowires (SiNWs) by using either thermal metallization or atomic layer deposition (ALD). The fabricated surfaces were characterized by X-ray photoelectron spectroscopy (XPS), energy dispersive X-ray spectroscopy (EDX), and reflectivity measurements. Surfaces with different TiO₂ based coating thicknesses were then used for phosphopeptide enric...

Context. Line-driven winds of hot, luminous stars are intrinsically unstable due to the line-deshadowing instability (LDI). In non-magnetic hot stars, LDI leads formation an inhomogeneous wind consisting small-scale, spatially separated clumps that can have great effects on observational diagnostics. However, for magnetic generated structures, dynamics, and diagnostics not been directly investi...

Synthetic host-guest chemistry is a versatile tool for biomedical applications. Characterization and detection of host-guest complexes in biological systems, however, is challenging due to the complexity of the biological milieu. Here, we describe and apply a mass spectrometric method to monitor the association and dissociation of nanoparticle (NP)-based host-guest interactions that integrates ...

We present a new algorithm for the efficient detection of collisions of geometrically complex objects. Our approach requires neither expensive setup nor sophisticated spatial data structures and is hence specifically suitable for handling deformable objects with arbitrarily shaped, closed surfaces. The algorithm is based on a Layered Depth Image (LDI) decomposition of the intersection volume. C...

Latent variable conditional models, including the latent conditional random fields as a special case, are popular models for many natural language processing and vision processing tasks. The computational complexity of the exact decoding/inference in latent conditional random fields is unclear. In this paper, we try to clarify the computational complexity of the exact decoding. We analyze the c...
