Imidazole derivative KK-42 is a well-known regulator of insect growth. KK-42 pretreatment has been shown to promote the survival of Macrobrachium nipponense infected with Aeromonas hydrophila, possibly via activation of superoxide dismutase (SOD). In this study, the cytMnSOD gene was cloned from the hepatopancreas of M. nipponense using the rapid amplification of cDNA ends technique. The full-l...
A separable potential formalism is used to describe the ππ and KK interactions in the I G (J P C) = 0 + (0 ++) states in the energy range from the ππ threshold up to 1.4 GeV. Introduction of relativistic propaga-tors into a system of Lippmann-Schwinger equations leads to a very good description of the data (χ 2 = 0.93 per one degree of freedom). Three poles are found in this energy region: f 0 ...
This paper deals with the problem of constant false alarm rate (CFAR) target detection in high-resolution ground synthetic aperture radar (SAR) images based on KK distribution. For the parameter estimation of KK distribution, the semi-experiential algorithm is analyzed firstly. Then a new estimation algorithm based on the particle swarm optimization (PSO) is proposed, which takes the discrepanc...
de Sitter inflationary expansion from a noncompact KK theory: a nonperturbative quantum (scalar) field formalism Abstract We develop a nonperturbative quantum scalar field formalism from a non-compact Kaluza-Klein (KK) theory using the induced-matter theory of gravity during inflation. We study the particular case of a de Sitter expansion for the universe.
OBJECTIVE To study the role of the ENPP1 Q121 variant on glucose homeostasis in whites from Italy. RESEARCH DESIGN AND METHODS We conducted case-control studies in 764 adults (from two independent samples of 289 nonobese and 485 obese individuals) and 240 overweight/obese children undergoing oral glucose tolerance testing (OGTT). Early-phase insulin secretion and insulin sensitivity (the insu...
An analysis of the J/ψ→ηη′γ decay by BESIII collaboration claims observation an exotic state η1(1855) with IGJPC=0+1−+. To establish its C-parity partner η1′(1855) in picture KK¯1(1400) molecular state, we propose that J/ψ→η1′(1855)η(′) receives main contributions from final interaction KK⁎(K+K⁎−, K−K⁎+, K0K¯⁎0, and K¯0K⁎0). Specifically, K K⁎ J/ψ→KK⁎ decays transform as η1′(1855)η(′), exchangi...
