A (v, k, t) trade can be used to construct new designs with various support sizes from a given t-design. H.L. Hwang (1986) showed the existence of (v, k, t) trades of volume 2t and the non-existence of trades of volumes less than 2t or of volume 2t + 1. In thIs paper, first we show that there exist (v, k, t) trades of volumes 2t + 2t1 (t ~ 1), 2t + 2t1 + 2t 2 (t ~ 2), 2t + 2t 1 + 2t 2 + 2t 3 (t...

Reactive oxygen species induce formation of 15-F(2t)-isoprostane (15-F(2t)-IsoP), a specific marker of in vivo lipid peroxidation, which is increased after myocardial ischemia and during the subsequent reperfusion. 15-F(2t)-IsoP possesses potent bioactivity under pathophysiological conditions. However, it remains unknown whether 15-F(2t)-IsoP, by itself, can influence myocardial ischemia-reperf...

In this paper we show that if a number field K contains a nonreciprocal unit u of degree s + 2t with s positive conjugates and 2t complex conjugates of equal moduli, where t > 2, then s = (2t+2m)q−2t for some integers m > 0 and q > 2. On the other hand, for any s and t > 2 related as above we construct a number field K with s real and 2t complex embeddings that contains a nonreciprocal unit u o...

In the work, we consider zero Mach number limit of compressible primitive equations in domain R2×2T or T2×2T. We identify to be with incompressible condition. The convergence behaviors are studied both and T2×2T, respectively. This paper takes into account high oscillating acoustic waves is an extension our previous work [29].

We consider matroids with the property that every subset of ground set size s is contained in a 2s-element circuit and t 2t-element cocircuit. say such matroid has (s,2s,t,2t)-property. A an (s,t)-spike if there partition into pairs union any Our main result all sufficiently large (s,2s,t,2t)-property are (s,t)-spikes, generalizing 2019 proved case where s=t. also present some properties (s,t)-...

15-F(2t)-isoprostane (15-F(2t)-IsoP), also termed 8-isoprostaglandin F(2alpha), is one of a series of prostanoids formed by free radical-mediated peroxidation of arachidonic acid and exerts potent biological actions such as vasoconstriction. We recently demonstrated that 15-F(2t)-IsoP is metabolized in humans to a major metabolite, 2,3-dinor-5,6-dihydro-15-F(2t)-IsoP (15-F(2t)-IsoP-M). 15-F(2t)...

The physics that is traditionally formulated in one–time-physics (1T-physics) can also be formulated in two-time-physics (2T-physics). The physical phenomena in 1T or 2T physics are not different, but the spacetime formalism used to describe them is. The 2T description involves two extra dimensions (one time and one space), is more symmetric, and makes manifest many hidden features of 1T-physic...

PURPOSE Increased reactive oxygen species may exhaust the antioxidant capability of human defense systems, leading to oxidative stress and cancer development. Urinary F2-isoprostanes, secondary end products of lipid peroxidation, are more accurate markers of oxidative stress than other available biomarkers. No prospective study has investigated whether levels of 15-F(2t)-isoprostane (15-F(2t)-I...
