Gut-derived norepinephrine (NE) has been shown to play a critical role in producing hepatocellular dysfunction in early sepsis, but it is not known whether alpha2-adrenoceptor activation mediates this dysfunction. We infused normal male adult rats with NE, NE plus the specific alpha2-adrenergic antagonist rauwolscine (RW), or vehicle (normal saline) for 2 h. Hepatocellular function was determin...

A new method of generating realistic three dimensional simulated breast 12 lesions known as diffusion limited aggregation (DLA) is presented, and compared 13 with the random walk (RW) method. Both methods of lesion simulation utilize a 14 physics-based method for inserting these simulated lesions into 2D clinical mammogram 15 images that takes into account the polychromatic X-ray spectrum, loca...

– The iterated random walk is a random process in which a random walker moves on a one-dimensional random walk which is itself taking place on a one-dimensional random walk, and so on. This process is investigated in the continuum limit using the method of moments. When the number of iterations n → ∞, a time-independent asymptotic density is obtained. It has a simple symmetric exponential form ...

A segmentation algorithm based on the random walk (RW) method, called 3D-LARW, has been developed to delineate small tumors or tumors with a heterogeneous distribution of FDG on PET images. Based on the original algorithm of RW [1], we propose an improved approach using new parameters depending on the Euclidean distance between two adjacent voxels instead of a fixed one and integrating probabil...

Most soil moisture sensor systems (SMSs) marketed for landscape irrigation respond to the dielectric permittivity of the soil. Compared to potable water (PW), reclaimed water (RW) may contain more salts, which can modify the dielectric permittivity of the soil and, hence, alter the readings of SMSs when measuring the soil water content. The main objectives of this experiment were to evaluate th...

We present a framework for evaluating and generating access control policies. The framework contains a modelling formalism called RW, which is supported by a model checking tool. RW is designed for modelling access control policies, and verifying their properties. The RW language is very expressive, allowing us to model complex access conditions which can depend on data values, other permission...

We use distorted wave electron scattering calculations to extract the weak charge form factor FW (q̄), the weak charge radius RW , and the point neutron radius Rn of 208Pb from the Lead Radius Experiment (PREX) parity-violating asymmetry measurement. The form factor is the Fourier transform of the weak charge density at the average momentum transfer q̄ = 0.475 fm−1. We findFW (q̄) = 0.204 ± 0.028 ...

This work assesses the efficiency of the Codacs system actuator (Cochlear Ltd., Sydney Australia) in different inner ear stimulation modalities. Originally the actuator was intended for direct perilymph stimulation after stapedotomy using a piston prosthesis. A possible alternative application is the stimulation of middle ear structures or the round window (RW). Here the perilymph stimulation w...

SCOPE We investigated the long-term effects of maternal high-fat consumption and post-weaning exercise on offspring obesity susceptibility and insulin resistance. METHODS C57BL/6J dams were fed either a high-fat (HFD, 40% kcal fat) or low-fat (LFD, 10% kcal fat) semi-synthetic diet during pregnancy and lactation. After weaning, male offspring of both maternal diet groups (mLFD; mHFD) received...
