Summary: This article proposes a combined control method based on the anti-control principle of chaos for a class of asymptotically stable linear systems with multiple controllers. The Lyapunov exponents method and equilibrium points analysis are used to investigate a higher-dimensional hyperchaotic system, which exhibits the largest number of positive Lyapunov exponents. The chaotic pseudo-random sequences of the system pass all NIST tests after preprocessing and demonstrate improved chaotic characteristics. An encryption algorithm for image information is designed based on these chaotic pseudo-random sequences, utilizing position scrambling, sequential diffusion, and reverse diffusion. Experimental results confirm the effectiveness and feasibility of the encryption algorithm. Moreover, security analyses including key sensitivity, differential attack, and statistical analysis are discussed, showing that the encryption algorithm has a sufficiently large key space and can be applied to secure communication.

Summary: A new optimization problem is proposed in this paper to improve the PWM control of an inverter for a generic RLE load by optimizing the zero sequence component waveform with special decision variables. The proposed PWM strategy is similar to both SVM and CBPWM methods, and simulation results show significant improvements compared to classical CBPWM strategies, with implementation possible on existing hardware.

Summary: Proteins with physiological functions have been found to interact with ribosomes and regulate gene expression during translation in both prokaryotes and eukaryotes. These regulatory nascent chains, also known as bacterial nascent chain-based mechanisms, can stall ribosomes and control translation arrest. Recent studies have shown that certain nascent chains can destabilize ribosomes and cause premature translation termination. This review highlights the importance of these bacterial mechanisms in regulating cellular functions.

Summary: Dissipative behaviors in biology, controlled by living cells, shape the complexities in biological materials. Synthetic dissipative materials controlled by fuel consumption have been developed, but living materials directly controlled by cell fuel consumption are unprecedented. In this paper, a chemical fuel-driven dissipative behavior of living materials is reported, using Staphylococcus epidermidis and telechelic block copolymers. The macroscopic phase transition is controlled by D-glucose, serving as both a disassembling agent and a biological fuel source. This work is a significant step towards designing emergent living materials.

Summary: This study reveals that excision of CP4-57 prophage in E. coli leads to the inactivation of tmRNA and switches the primary ribosome rescue pathway from trans-translation to ArfA/RF2. This switch not only rearranges the proteome landscape and phenotype of E. coli, but also provides a novel example of trans-translation-dependent regulation and redefines the physiological roles of prophage excision.

Summary: Here, an ATP-responsive nanoparticle, (NP)-N-GroEL, was synthesized by DNA hybridization between a gold nanoparticle and GroEL protein. The (NP)-N-GroEL retained its machine-like function and could capture and release denatured green fluorescent protein in response to ATP. It exhibited significantly higher ATPase activity compared to its precursor (cys)GroEL and DNA-functionalized analogue. Furthermore, it was found that (NP)-N-GroEL could be extended to double-layered (GroEL)2 NP.

Summary: Olfactory receptors (ORs) in olfactory sensory neurons mediate olfaction and require the assistance of receptor-transporting proteins (RTPs) for functional expression. This study examined the interactome of RTP1S and OR using proximity biotinylation and revealed the involvement of HSPA6 and STAU2 in the trafficking process of OR through interaction with RTP1S.

Summary: We report a uniform composite hydrogel that displays substantial mechanical nonreciprocity, owing to direction-dependent buckling of embedded nanofillers. This material exhibits an asymmetric deformation when subjected to local interactions, which can induce directional motion of various objects. This material could promote the development of nonreciprocal systems for practical applications such as energy conversion and biological manipulation.

Summary: The study developed a cell-free method using a reconstituted cell-free protein synthesis system (PURE system) to perform N-terminal acetylation and myristoylation of nascent proteins in vitro. The proteins synthesized using the PURE system were successfully modified in the presence of modifying enzymes. The study also demonstrated protein myristoylation in giant vesicles, leading to partial localization to the membrane. The PURE-system-based strategy is useful for controlled synthesis of post-translationally modified proteins.

Summary: Cellulose nanofibers (CNFs) prepared via TEMPO-mediated oxidation are used as pseudocatalysts for enhancing the aluminum powder/pure water reactions. The formation of TEMPO-CNFs on the native Al2O3 thin layer captures Al3+ ions and restricts OH- ions nearby, generating a highly alkaline condition and accelerating the reaction of metallic Al with water. This leads to a nearly 100% Al/H-2 conversion at temperatures below 50 degrees C.

Summary: Dissipative behaviors in biology are controlled by living cells and shape the complexities of biological materials. The development of synthetic dissipative materials controlled by time-dependent consumption of fuels has been inspired by this concept. In this paper, we report a chemical fuel-driven dissipative behavior in living materials composed of Staphylococcus epidermidis and telechelic block copolymers, controlled by both a competitive disassembling agent and a biological fuel source. Our work is a significant step towards constructing a synthetic dissipative living system and provides new knowledge for designing emergent living materials.
