Recently Bai and Yang in [On HSS-based iteration methods for weakly nonlinear systems, Appl. Numer. Math. 59 (2009) 2923–2936.] proposed the Picard-HSS iteration method to solve the system of nonlinear equations Ax = φ(x), where A ∈ Cn×n is a nonHermitian positive definite matrix and φ : D ⊂ C → C is continuously differentiable function defined on the open complex domain D in the n-dimensional ...

Heated scallop-shell (HSS) nano-particles, prepared using a wet grinding mill, and microparticles were examined for their antibacterial activity against vegetative bacterial cells and spores. The median diameters of the nano-particles and micro-particles were approximately 20 nm and 30 µm, respectively. The antibacterial activity of HSS against Escherichia coli increased with an increase in con...

The mRNA coding for the rat liver S14 protein (Mr 17,000; pI 4.9) is rapidly induced by triiodothyronine (T3) (Jump, D. B., Narayan, P., Towle, H. C., and Oppenheimer, J. H. (1984) J. Biol. Chem. 259, 2789-2797). In an effort to define the molecular basis for the rapid increase in mRNAS14, the in vitro run-on activity and chromatin structure of the S14 gene was examined. Following injection of ...

PURPOSE Beta igh3 is a transforming growth factor-beta-inducible cell adhesion molecule and its mutations are responsible for human autosomal dominant corneal dystrophies. Previously, we have studied the molecular properties of beta igh3 in vitro and reported that beta igh3 polymerizes to form a fibrillar structure and interacts with several extracellular matrix proteins including type I collag...

Hepatic stimulator substance (HSS) protects liver cells from various toxins by alleviating lesions caused in the mitochondria. This paper demonstrates the necessity of the conserved CXXC catalytic motif (C62-C65) for the mitochondria-targeted anti-apoptotic activity of HSS. Mutating the conserved CXXC motif eliminated the protective effects against H(2)O(2)-induced apoptosis and diminished the ...

It is known that the Hermitian and skew-Hermitian splitting (HSS) iteration method is an efficient solver for non-Hermitian positive definite linear system of equations. In [M. Benzi, SIAM J. Matrix Anal. Appl. 31 (2009) 360–374] Benzi proposed a generalization of the HSS (GHSS) iteration method. In this paper, we present a two-parameter version of the GHSS (TGHSS) method and investigate its co...

Eine verlängerte Werkzeuglebensdauer bei der Gewindefertigung ist durch eine Neugestaltung inneren Kühlschmierstoffzufuhr am Werkzeug möglich. Der Einsatz additiver Fertigungsverfahren wie dem Laser Powder Bed Fusion erlaubt die Fertigung innen liegender und komplexer Kanal- Düsengeometrien. In umfangreichen Einsatztests konnten Prozesssicherheit Potenziale additiv gefertigter Gewindeform- Gewi...

Hot spots (HSs) are regions of enhanced radio emission produced by supersonic jets at the tip of the radio lobes of powerful radio sources. Obtained with the Very Large Telescope (VLT), images of the HSs in the radio galaxy 3C 445 show bright knots embedded in diffuse optical emission distributed along the post-shock region created by the impact of the jet into the intergalactic medium. The obs...

Newton-HSS methods, that are variants of inexact Newton methods different from Newton-Krylov methods, have been shown to be competitive methods for solving large sparse systems of nonlinear equations with positive definite Jacobian matrices [Bai and Guo, 2010]. In that paper, only local convergence was proved. In this paper, we prove a Kantorovich-type semilocal convergence. Then we introduce N...
