Prostaglandins (PGs) of the J2 series form in vivo and exert effects on a variety of biological processes. While most of PGs mediate their effects through G protein-coupled receptors, the mechanism of action for the J2 series of PGs remains unclear. Here, we report the PGJ2 and its derivatives are efficacious activators of peroxisome proliferator-activated receptors alpha and gamma (PPAR alpha ...

that produce the \best ̄t" to the data. Here, n denotes the noise or ̄tting error. By the term \best ̄t," we mean the minimization of the ̄tting error in some sense. For example, typical norm or norm-like functionals used as arguments in the above minimization problem are: 2 knk1 = ess. supt jn(t)j; the L1 norm. 2 knk2 = ¡R1 0 jn(t)j2 dt¢1=2; the L2 norm (energy). 2 knk2;± = ¡R1 0 e2±tjn(t)j2 dt¢1=...

If there exists i ∈ Ys which is not among the s-top ranked ones, then we could replace class i in position ji within Ys with class k / ∈ Ys such that pk,t > pi,t obtaining a smaller loss. Next, we show that the optimal ordering within Y ∗ s,t is precisely ruled by the nonicreasing order of pi,t. By the sake of contradiction, assume there are i and k in Y ∗ s,t such that i preceeds k in Y ∗ s,t ...

We study the higher-order nonlinear dispersive equation ∂tu+ ∂ 2j+1 x u = ∑ 0≤j1+j2≤2j aj1,j2∂ j1 x u∂ j2 x u, x, t ∈ R. where u is a real(or complex-) valued function. We show that the associated initial value problem is well posed in weighted Besov and Sobolev spaces for small initial data. We also prove ill-posedness results when a0,k 6= 0 for some k > j, in the sense that this equation cann...

This paper deals with bases in a finite–dimensional Hilbert space. Such a space can be realized as a subspace of the representation space of SU2 corresponding to an irreducible representation of SU2. The representation theory of SU2 is reconsidered via the use of two truncated deformed oscillators. This leads to replace the familiar scheme {j2, jz} by a scheme {j2, vra}, where the two–parameter...

Filtrates from nematode-parasitic fungi have been reported to be toxic to plant-parasitic nematodes. Our objective was to determine the effects of fungal filtrates on second-stage juveniles and eggs of Heterodera glycines. Eleven fungal species that were isolated from cysts extracted from a soybean field in Florida were tested on J2, and five species were tested on eggs in vitro. Each fungal sp...

Prior work described the baseline version J1 of a spatial domain image steganographic embedding based on manipulation of the frequency domain, and presented a topological approach to the problem. This paper modifies the embedding and extraction processes of J1 to allow for larger payload. The improved steganographic algorithm is called J2, and is more robust to steganographic detection than J1....

Quantum systems where the position and momentum are in the ring Zd (d is an odd integer) are considered. Symplectic transformations are studied, and the order of Sp(2,Zd) is calculated. Quantum tomography is also discussed. It is shown that measurements (used in the inverse Radon transform) need to be made on J2(d) lines (where J2(d) is the Jordan totient function).
