The application of incentives, such as reward and punishment, is a frequently applied way for promoting cooperation among interacting individuals in structured populations. However, how to properly use the incentives still challenging problem incentive-providing institutions. In particular, since implementation incentive costly, explore optimal protocol, which ensures desired collective goal at minimal cost, worthy study. this work, we consider positive negative population whose conflicting...

Localization of bicoid (bcd) mRNA to the anterior and oskar (osk) posterior Drosophila oocyte is critical for embryonic patterning. Previous genetic studies implicated exuperantia (exu) in bcd localization, but its role this process not understood. We have biochemically isolated Exu show that it part a large RNase-sensitive complex contains at least seven other proteins. One these proteins was identified as cold shock domain RNA-binding protein Ypsilon Schachtel (Yps), which we binds...

Layered Li-rich 3d-transition-metal cathode materials, xLi2MnO3·(1–x)LiMO2, have increasingly triggered immense interest for their use in Li-ion batteries due to advantages terms of energy density. Nevertheless, poor cycle and rate performances cause limitations practical commercial applications. We modified the material with boron bulk doping carbon surface modification form a B-doped layered@spinel@carbon heterostructure. Herein, B-doping can increase lattice spacing favorable Li+...

In the "14th Five-Year Plan" period, emphasis is made on green and low-carbon initiatives, which has become a defining feature of China's development, it great significance to help enterprises realize sustainable development under guidance environmental regulation achieve goal "dual-carbon". At first, this research analyzes decision-making process between government using evolutionary game model. Moreover, TOPSIS method, paper constructs indicators corporate performance, empirically examines...

SET domain proteins are histone lysine methyltransferases (HMTs) that play essential roles in development. Here we show for the first time methylation occurs both germ cells and somatic of Drosophila ovary, demonstrate vivo an HMT, product eggless (egg) gene, is required oogenesis. Egg a protein similar to human SETDB1 its mouse ortholog ESET. These members small family HMTs contain bifurcated domains. Because depletion tissue culture cell-lethal, ESET mutation causes very early...

Pro-social punishment and exclusion are common means to elevate the level of cooperation among unrelated individuals. Indeed, it is worth pointing out that combined use these two strategies quite across human societies. However, still not known how a strategy where switched can promote from theoretical perspective. In this paper, we thus propose different switching strategies, namely peer based on exclusion, pool exclusion. Individuals adopting will punish defectors when their numbers below...

The ideal composite electrolyte for the pursued safe and high‐energy‐density lithium metal batteries (LMBs) is expected to demonstrate peculiarity of superior bulk conductivity, low interfacial resistances, good compatibility against both Li‐metal anode high‐voltage cathode. There no synchronously meet all these requirements yet, battery performance inhibited by absence effective design. Here we report a unique “concentrated ionogel‐in‐ceramic” silanization (SCE) validate an design strategy...

Abstract Realizing fast charging in high‐specific‐energy lithium metal batteries (LMBs) remains a significant challenge. Here, oleophilic garnet suspension electrolyte design is reported, using inorganic solid modified by low‐surface‐energy 1H,1H,2H,2H‐perfluorooctyl trichlorosilane (PFOTS), to address the dilemma of and high specific energy LMBs. With electrolytes, ionic conductivity carbonate increased ≈20%. Importantly, Li + transference number ≈50% (reaching 0.57). Furthermore, regulates...

Abstract Porous mullite hollow fiber membranes were prepared with a combined phase-inversion and sintering method, using three additives including yttrium stabilized zirconia (YSZ), small particles (SMP), titanium oxide (TiO 2 ) to promote the particle sintering. The results indicated that all could improve performance of due decrease in activation energy grains. Both YSZ TiO react grains generate composite oxides (e.g., ZrSiO 4 Al 5 during sintering, following reaction-sintering mechanism....

Microscopic strategy update rules play an important role in the evolutionary dynamics of cooperation among interacting agents on complex networks. Many previous related works only consider one <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">fixed</i> rule, while real world, individuals may switch, sometimes periodically, between rules. It is particular theoretical interest to investigate under what conditions periodic switching facilitates...

Ionogels, which are being considered as quasi-solid electrolytes for energy-storage devices, exhibited technical superiority in terms of nonflammability, negligible vapor pressure, remarkable thermostability, high ionic conductivity, and broad electrochemical stability window. However, their applications lithium metal batteries (LMBs) have been hindered by several issues: poor compatibility with Li-metal anodes high-voltage cathodes, viscosity, inadequate wettability. Little attention has...
