Despite becoming an octogenarian this year, Prof. C. L. Tsou (Zou chenglu)still keeps strictly to a busy work schedule, coming to his laboratory at 8 am and leaving at 4 pmevery day. At weekends, he buries himself in literature, reading, pondering and writing. In short,work is the eternal theme and major part of his life. Recently, however, he took his doctor's adviceand added a walk to his daily routine. Prof. Tsou was born in 1923 in Wuxi City, Jiangsu *** the locals have a unique dialect, he speaks perfect Mandarin. He also speaks Shanghaidialect with an accent, which can be attributed to his work in Baoshan, a suburban county inShanghai in the mid-1960s. In 1941, after he graduated from the Nankai Middle School in Chongqing,the wartime capital of China, he was admitted to the National Southwest Associate University as achemistry major and graduated in 1945. Two years later, he went to England on a state scholarshipand came home in 1951, after obtaining his Ph.D. in biochemistry from Cambridge University. For 20years he worked at the Shanghai Institute of Biochemistry, a CAS affiliate, and in 1971 he moved tothe CAS Institute of Biophysics (IBP) in Beijing, where he personally guided the founding of theNational Laboratory for Biomacromolecules, working there till now. During the past 50 years, he usedto serve as a member of the CAS Presidium of Academic Divisions (CASAD), director of the AcademicDivision of Biology, and chairman of the executive council under Chinese Society of Biochemistry andMolecular Biology. In addition, he served from 1978 to 1997 on the 5^(th) to 8^(th) NationalCommittee of the Chinese People's Political Consultative Conference, the national top advisory bodyand also its 8th standing committee. In 1980, he was elected to CAS. He is a fellow of the ThirdWorld Academy of Sciences and an honorary member of the American Society for Biochemistry andMolecular Biology. For many years, he has sat as a member of the editorial board or

A programmable algorithm using bonddissociation energies has been proposed for the prediction of reaction pathways. It has been successfully applied to a gas-phase reaction of F2+CH3Cl, with the accurate revelation of the most favorable product CF4 and its corresponding reaction pathway. This acts as an inspiring example of chemical empiricism 2.0, and may open the door for the large-scale prediction of reaction pathways at the age of big data.

Many real-world optimization problems involve multiple conflicting objectives. Such problems are called multiobjective optimization problems(MOPs). Typically, MOPs have a set of so-called Pareto optimal solutions rather than one unique optimal solution. To assist the decision maker(DM) in finding his/her most preferred solution, we propose an interactive multiobjective evolutionary algorithm(MOEA)called iDMOEA-εC, which utilizes the DM’s preferences to compress the objective space directly and progressively for identifying the DM’s preferred region. The proposed algorithm employs a state-of-the-art decomposition-based MOEA called DMOEA-εC as the search engine to search for solutions. DMOEA-εC decomposes an MOP into a series of scalar constrained subproblems using a set of evenly distributed upper bound vectors to approximate the entire Pareto front. To guide the population toward only the DM’s preferred part on the Pareto front, an adaptive adjustment mechanism of the upper bound vectors and two-level feasibility rules are proposed and integrated into DMOEA-εC to control the spread of the population. To ease the DM’s burden, only a small set of representative solutions is presented in each interaction to the DM,who is expected to specify a preferred one from the set. Furthermore, the proposed algorithm includes a two-stage selection procedure, allowing to elicit the DM’s preferences as accurately as possible. To evaluate the performance of the proposed algorithm, it was compared with other interactive MOEAs in a series of experiments. The experimental results demonstrated the superiority of iDMOEA-εC over its competitors.

This paper further investigates cluster synchronization in a complex dynamical network with *** cluster contains a number of identical dynamical systems,however,the sub- systems composing the two clusters can be different,i.e.,the individual dynamical system in one cluster can differ from that in the other *** synchronization within each cluster is possible only if each node from one cluster receives the same input from nodes in other *** this case,the stability condition of one-cluster synchronization is known to contain two terms:the first accounts for the contribution of the inner-cluster coupling structure while the second is simply an extra linear term,which can be deduced by the'same-input'*** the connection graph stability method,the authors obtain an upper bound of input strength for one cluster if the first account is known,by which the synchronizability of cluster can be *** different clusters,there are different upper bound of input strength by virtue of different dynamics and the corresponding cluster ***,two illustrative examples are presented and the numerical simulations coincide with the theoretical analysis.

The classical critical Trudinger-Moser inequality in R^(2)under the constraint∫_(R_(2))(|▽u|^(2)+|u|^(2))dx≤1 was established through the technique of blow-up analysis or the rearrangement-free argument:for anyτ>0,it holds that sup u∈H^(1)(r^(2)fR^(2)(τ|U|^(2)+|▽u|^(2)dx≤1∫_(R^(2)(E^4π|u|^(2)-1)dx≤C(τ)lutions to the following Sciridinger equations with critical exponeitial growth:-Δu+V(x)u=f u)in R^(2),(0.1)where V(x)≥0 and vanishes on an open set of R^(2)and f has critical exponential *** a positive constant lower bound for the potential V(x)(e.g.,the Rabinowitz type potential)has been the standard assumption when one deals with the existence of solutions to the above Schrodinger equations when the nonlinear term has the exponential *** existence result seems to be the first one without this standard assumption.

Age and body size are two important demographic traits that determine the life history strategies of populations and species. We measured these two parameters ofRana amurensis, at a 900 m and a 500 m altitude site in northeastern China. At the two sites, age at first reproduction was 2 years for males and 3 years for females. The maximum age of males and females at the high-altitude site was 6 and 7 years, and 5 and 7 years at the low-altitude population, respectively. Females were significantly larger than males in both populations, due to greater age in both the high- and low-altitude sites, Body size of either males or fe- males did not differ significantly between populations; only males showed increased body size at the high-altitude site when age effect was statistically controlled for. The increased cline of male body size may be attributable to delayed maturation of the sex due to a shorter growing season at high altitudes

Rational design and development of cost-effective, highly active and durable bifunctional electrocatalysts towards oxygen redox reactions is of critical importance but great challenge for the broad implementation of next-generation metal-air batteries for electric transportation. Herein, a high-performance electrocatalyst of cobalt and zinc sulfides nanocrystals embedded within nitrogen and sulfur co-doped porous carbon is successfully designed and derived from bimetallic metal-organic frameworks of cobalt and zinc containing zeolitic imidazolate frameworks. The unique nanostructure contains abundant electrocatalytic active sites of sulfides nanocrystals and nitrogen and sulfur dopants which can be fast accessed through highly porous structure originate from both zinc vaporization and sulfurization processes. Such bifunctional electrocatalyst delivers a superior half-wave potential of 0.86 V towards oxygen reduction reaction and overpotential of 350 mV towards oxygen evolution reaction, as well as excellent durability owing to the highly stable carbon framework with a great graphitized portion. The performance boosting is mainly attributed to the unique nanostructure where bimetallic cobalt and zinc provide synergistic effect during both synthesis and catalysis processes. The design and realization pave a new way of development and understanding of bifunctional electrocatalyst towards clean electrochemical energy technologies.

The purpose of this paper is five-fold. First, we employ the harmonic analysis techniques to establish the following Hardy–Littlewood–Sobolev inequality with the fractional Poisson kernel on the upper half space ■ where f ∈ L^p(?R_+~n), g ∈ Lq(R_+~n) and p, q'∈(1, +∞), 2 ≤α lutions to the integral system of the Euler–Lagrange equations associated with the extremals of the fractional Poisson kernel. Finally, by using the method of moving plane in integral forms, we prove that extremals of the Hardy–Littlewood–Sobolev inequality with the fractional Poisson kernel must be radially symmetric and decreasing about some point ξ_0 ∈ ?R_+~n. Our results proved in this paper play a crucial role in establishing the Stein–Weiss inequalities with the Poisson kernel in our subsequent paper.

By using a pressure-based method and the finite volume method in the framework of the time dependent Reynolds-averaged Navier-Stokes equations, the authors studied the unsteady process of ventilated cavities generated forcing air through an orifice in a 2D hydrofoil without natural cavitation physically. The computation was carried out with the Volume Of Fluid （VOF） technique to track the gas-liquid two-phase interface. The results of simulation indicate that the ventilation rate is an important parameter in determining the morphology of cavity. There exists a critical value to convert sheet cavity into supereavity. A high ventilation rate can induce a two phase interface fluctuation and enable the ventilated eavitating flow to present a characteristic of periodicity.
