In this paper, we establish the existence of nonoscillatory solutions to neutral dynamic equations with positive and negative coefficients on time scales form (x(t) ? ?ba p(t, ?)x(1(t, ?))??)? + ?li =1 ri(t)x(?i(t)) ?m j=1 sj(t)x(?j(t)) = 0. Two examples are included illustrate our presented results. approaches, a key role is played by fixed point technique.

Ultrasonography uses multiple piezo-electric element probes to image tissues. Current time-domain beamforming techniques require the signal at each transducer-element to be sampled at a rate higher than the Nyquist criterion, resulting in an extensive amount of data to be received, stored and processed. In this work, we propose to exploit sparsity of the signal received at each transducer-eleme...

Objective This study compared the symptomatic emotional traits of elderly South Korean patients with hwa-byung and those with depression. Methods We enrolled 58 patients with hwa-byung, 180 patients with depression, and 181 healthy control subjects. All participants completed the Hwa-byung Scale, Hamilton Depression Rating Scale (HDRS), Beck Depression Inventory (BDI), Geriatric Depression Sc...

A novel thermophilic and endospore-forming Gram-positive bacterium capable of assimilating and isomerizing l-ribose was isolated from a volcanic area in Likupang, Indonesia. The isolate, RI-39(T), was able to grow at high temperatures (37-60 degrees C); optimum growth was observed at pH 6.5 and 45 degrees C. The strain contained MK-7 (87 %) as the main respiratory quinone and had a DNA G+C cont...

formulation Let us, before proceeding, for convenience first define the index sets of the dynamic fields, Jd = {1, . . . ,Md}, static (dynamic) fields, Js = {Md + 1, . . . ,M}, dynamic states, Id = {1, . . . , Nd}, and static (dynamic) states, Is = {Nd + 1, . . . , N}. The equations (6.2)–(6.6) together constitute the dynamical system behind the model that can be written in the form ż = f(t, z,...

(A) Let x1 ∈ R n be arbitrary and H1 ∈ R n,n be nonsingular arbitrary. Set i = 1. (B) Compute the residual ri = Axi − b. If ri = 0, then stop, xi solves the problem. Otherwise compute si = HiA T vi, where vi ∈ R n is arbitrary, save that v1, . . . , vi are linearly independent. If si 6= 0, then go to (C). If si = 0 and r T i vi = 0, then set xi+1 = xi, Hi+1 = Hi and go to (F). If si = 0 and r T...
