Based on the existing Land Surface Physical Process Models(Deardorff, Dickinson, LIU, Noilhan, Seller, ZHAO), a Comprehensive Land Surface Physical Process Model (CLSPPM) is developed by considering the different physical processes of the earth's surface-vegetation-atmosphere system more completely. Compared with SiB and BATS, which are famous for their detailed parameterizations of physical variables, this simplified model is more convenient and saves much more computation time. Though simple, the feas...

In this article, we prove the Hyers-Ulam-Rassias stability of the following Cauchy-Jensen functional inequality：‖f （x）＋ f （y）＋ 2. （z）＋ 2. （w）‖ ≤‖ 2. x ＋ y2.＋ z ＋ w ‖（0.1）This is applied to investigate isomorphisms between C＊-algebras, Lie C＊-algebras and JC＊-algebras, and derivations on C＊-algebras, Lie C＊-algebras and JC＊-algebras, associated with the Cauchy-Jensen functional equation 2. （x ＋ y/2.＋ z ＋ w） = f（x）＋ f（y）＋ 2.（z）＋ 2.（w）.

The anti-allergic drug,N-(3,4-dimethoxycinnamonyl) anthranilic acid(3,4-DAA),is a synthetic anthranilic acid derivative that has been used therapeutically in Japan for many *** this study,to investigate the effects of 3,4-DAA in allograft immunorejection model,liver orthotopic transplants were performed using inbred male Dark Agouti donors and Lewis rat recipients(allografts).The levels of indoleamine 2.3-dioxygenases (IDO) enzymic activities in five groups,allografts(control),DMSO-treated group(vehicle control),2.0 mg/kg/day 3,4-DAA-treated group and 2.0 mg/kg/day 3,4-DAA+5mg/ml 1-Methyl-D-tryptophan(1-MT)treated group were confirmed by determination of L-kynurenine(L-Kyn) *** serum alanine aminotransferase(ALT) levels in 3,4-DAA-treated rats significantly decreased compared with those in mock and control group while treatment of 1 -MT in allografts led to the opposite *** of 3,4-DAA reduced histological severity of allograft immunorejection,decreased serum levels of cytokines tumor necrosis factor-alpha(TNF-α) and interferon-gamma(IFN-γ),and raised serum levels of interleukin-10(IL-10), suggesting 3,4-DAA has both anti-inflammatory and anti-immunorejection properties through IDO in immune regulation,and may therefore be useful in filling an unmet need,in the treatment of allograft immunorejection.

The protocol testing technology used in the next generation Internet should satisfy some new challenges and requirements. This paper focuses on the test suite description and test implementation techniques. TTCN-3 is chosen as the test suite description language and extended in both syntax and semantics to satisfy the requirements of protocol robustness testing. PITSv3, a protocol integrated testing system based on TTCN-3, is developed, and the extensions for robustness testing are implemented. Finally, two practical test applications are presented.
