This paper presents an anlysis based on the momentum conservation equations of a redundant free-flying spacecraft/manipulator system, acting in zero-gravity environment. In order to follow a predefined end-effector path, the inverse kinematics at velocity level is considered. The redundancy i solved alternatively in terms of pseudoinverses and null-space components of the manipulator inertia ma...

White spot syndrome virus (WSSV), the most contagious pathogen of cultured shrimp, causes mass mortality, leading to huge economic loss to the shrimp industry. The lack of effective therapeutic or prophylactic measures has aggravated the situation, necessitating the development of antiviral drugs. With this objective, the antiviral activity of the drug, (TP22C derived from the terrestrial plant...

This paper is a case study in proof mining applied to non-effective proofs in nonlinear functional anlysis. More specifically, we are concerned with the fixed point theory of nonexpansive selfmappings f of convex sets C in normed spaces. We study the Krasnoselski iteration as well as more general so-called Krasnoselski-Mann iterations. These iterations converge to fixed points of f only under s...

The chemical components and biological activity of Camellia mistletoe, Korthalsella japonica (Loranthaceae) are relatively unknown compared to other mistletoe species. Therefore, we investigated the phytochemical properties and biological activity of this parasitic plant to provide essential preliminary scientific evidence to support and encourage its further pharmaceutical research and develop...

While most researchers in industrial organization agree that the neoclassical, cost-minimizing, unitary, view of the firm is restrictive, it is still the main object of anlysis in the literature. We review the literature in industrial organization and the place occupied by a richer view of the firm both before and after Grossman & Hart (1986) (GH). Before GH, integration was viewed as a way to ...

The main effort of theoretical studies on neutrino-nucleus reactions at intermediate energies (few hundreds MeV) has been devoted to quasi-elastic (QE) charged-current (CC) reactions. This is due to the fact that water Cerenkov detectors only detect outgoing charged leptons. New experiments such as K2K aim to measure the espectrum of outgoing nucleons produced in neutral currents (NC) in this e...

Many healtcare organizations face the challenge of scaling up effective health care delivery. There is a growing agreement that a better understanding of the structure of the healthcare system is needed to achieve that goal. Networks analysis provides the formal framework of thought to understand such systems. Given the definition of health care system as as a network of actors who aim to provi...

INTRODUCTION Dyslipidemia is often detected in patients with chronic kidney disease (CKD). Previous studies of the relationship between lipid profiles and kidney function have yielded variable results. We aimed to investigate the correlation between serum lipid levels and kidney function evaluated by measured glomerular filtration rate (mGFR) in Chinese patients with CKD. METHODS A cross-sect...
