Phase-Transition-Induced Surface Reconstruction of Rh Site in Intermetallic Alloy for Propane Dehydrogenation.

The fine-tuning of the geometric and electronic structures of active sites plays a crucial role in catalysis. However, the intricate entanglement between the two aspects results in a lack of interpretable design for active sites, posing a challenge in developing high-performance catalysts. Here, we find that surface reconstruction induced by phase transition in intermetallic alloys enables synergistic geometric and electronic structure modulation, creating a desired active site microenvironment for propane dehydrogenation.

Improving Pareto Local Search Using Cooperative Parallelism Strategies for Multiobjective Combinatorial Optimization.

Pareto local search (PLS) is a natural extension of local search for multiobjective combinatorial optimization problems (MCOPs). In our previous work, we improved the anytime performance of PLS using parallel computing techniques and proposed a parallel PLS based on decomposition (PPLS/D). In PPLS/D, the solution space is searched by multiple independent parallel processes simultaneously.

The potential role of eyestalk in the immunity of Litopenaeus vannamei to Vibrio parahaemolyticus infection II. From the perspective of long non-coding RNA.

Long non-coding RNAs (lncRNAs) have been linked to immunological modulation. Unfortunately, little is known about the processes of immune control in shrimp. In crustaceans such as Litopenaeus vannamei, a prominent aquaculture species, the X-organ-sinus gland complex (XO-SG) in the eyestalk is an essential neuroendocrine regulatory organ.

The potential role of eyestalk in the immunity of Litopenaeus vannamei to Vibrio infection.

The X-organ-sinus gland complex (XO-SG) in the eyestalk is an important neuroendocrine regulatory organ of crustaceans such as Litopenaeus vannamei, a prominent aquaculture species. The current study found significant changes in the enzyme activities of ALP, ACP, and T-SOD of hepatopancreatic in response to Vibrio parahaemolyticus exposure following eyestalk ablation, indicating that they were all involved in the immunological regulation of shrimps against V. parahaemolyticus infection.

Effect of the oat β-glucan on the development of functional quinoa (Chenopodium quinoa wild) milk.

This study aimed to produce novel plant-based milk from quinoa with the addition of oat β-glucan (OGB). The stability of quinoa milk was characterized by zeta potential, particle size, separation index (SI), rheological property, backscattered light intensity (ΔBS), and microstructure. Results showed that OGB addition efficiently prevented the phase separation of quinoa milk, and the highest SI and zeta potential values were obtained at the optimal pH 6.

Homotopic Convex Transformation: A New Landscape Smoothing Method for the Traveling Salesman Problem.

This article proposes a novel landscape smoothing method for the symmetric traveling salesman problem (TSP). We first define the homotopic convex (HC) transformation of a TSP as a convex combination of a well-constructed simple TSP and the original TSP. The simple TSP, called the convex-hull TSP, is constructed by transforming a known local or global optimum.

PPLS/D: Parallel Pareto Local Search Based on Decomposition.

Pareto local search (PLS) is a basic building block in many metaheuristics for a multiobjective combinatorial optimization problem. In this paper, an enhanced PLS variant called parallel PLS based on decomposition (PPLS/D) is proposed. PPLS/D improves the efficiency of PLS using the techniques of parallel computation and problem decomposition.

Integrative transcriptome analysis and discovery of genes involving in immune response of hypoxia/thermal challenges in the small abalone Haliotis diversicolor.

In recent years, the abalone aquaculture industry has been threatened by the deteriorating environmental conditions, such as hypoxia and thermal stress in the hot summers. It is necessary to investigate the molecular mechanism in response to these environmental challenges, and subsequently understand the immune defense system. In this study, the transcriptome profiles by RNA-seq of hemocytes from the small abalone Haliotis diversicolor after exposure to hypoxia, thermal stress, and hypoxia plus thermal stress were established.

Transcriptome analysis provides insights into differentially expressed genes and long noncoding RNAs involved in sex-related differences in Amur sturgeon (Acipenser schrenckii).

In the present study, the next-generation sequencing technology was used to develop a transcriptome database of gonad and liver from 3-year-old male and female Amur sturgeons (Acipenser schrenckii). A total of 139,406 unigenes were generated after the Illumina Hiseq. 2500 sequence and assembled by Trinity.
