Zuckerkandl’s organ (ZK) is an extra adrenal para-ganglion and has the ability to express glial cell line derived neurotrophic factor (GDNF) and transforming growth factor (TGF). It is also a source of dopamine and norepinephrine. In the present study, the neuroprotective and restorative potential of ZK was studied by transplanting it into the striatum of adult rats either before or after the i...

This paper deals with singular Schrödinger operators of the form−d2dx2+∑k∈Zγkδ(⋅−zk),γk∈R, in L2(ℓ−,ℓ+), where δ(⋅−zk) is Dirac delta-function supported at zk∈(ℓ−,ℓ+) and (ℓ−,ℓ+) a bounded interval. It will be shown that interaction strengths γk points zk can chosen such way essential spectrum part discrete this self-adjoint operator coincide prescribed sets on real line.

The ZK-Crypt combination compact hardware stream cipher engines each include a true random number generator, a stream cipher and a data authenticator based on a fast compact engine and proven "noise sources". The ZK-Crypt II 7.0 K gate and ZK-Crypt 8.2 K gate "engines" output a 32 bit word at each clock cycle with 128 and 160-bit keys, maximizing throughput with very low energy per enciphered b...

BACKGROUND Antiestrogens of the selective estrogen receptor modulator (SERM) type, such as tamoxifen, have two major limitations: their mixed agonist and antagonist profile and the development of tumor resistance. We characterized two new pure antiestrogens-ZK-703 and ZK-253-that belong to the class of specific estrogen receptor destabilizers (SERDs), which includes fulvestrant, and compared th...

We revisit the question of Zero-Knowledge PCPs, studied by Kilian, Petrank, and Tardos (STOC ’97). A ZK-PCP is defined similarly to a standard PCP, except that the view of any (possibly malicious) verifier can be efficiently simulated up to a small statistical distance. Kilian et al. obtained a ZK-PCP for NEXP in which the proof oracle is in EXP. They also obtained a ZK-PCP for NP in which the ...

The conventional Newton’s method for finding a zero of a function F : R → R, assuming that (F ′(y))−1 exists for at least some y in R, is the familiar iteration: pick z0 in R n and define zk+1 = zk − (F ′(zk))−1F (zk) (k = 0, 1, 2, . . . ), hoping that z1, z2, . . . converges to a zero of F . What can stop this process from finding a zero of F ? For one thing, there might not be a zero of F . F...
