The formation of animal breeds usually begins with a small subsample from their ancestral population. Deleterious mutations accumulate in the population under genetic drift, inbreeding, and artificial selection during development maintenance traits desired by humans. White raccoon dogs are among most popular farmed dogs, but white more susceptible to disease have lower reproductive ability. However, accumulation deleterious this breed is largely unknown. By analyzing comparing whole-genome...
A high-quality reference genome coupled with resequencing data is a promising strategy to address issues in conservation genomics. This has greatly enhanced the development of plans for endangered species. Pangolins are fascinating animals variety unique features. Unfortunately, they most trafficked wild animal world. In this study, we assembled chromosome-scale HiFi long reads and Hi-C short Chinese Malayan pangolin provided two new representative genomes We found great improvement...
Mold has long been a priority because of its potential threat to human health and reduction in the value wood. Most traditional mold inhibitors have toxic effects on environment, so developing safe nontoxic remains challenge. In this study, tannic acid carbon dots (TA-CDs) were obtained via straightforward one-step hydrothermal process. Subsequently, Cu2+ cross-linked dot nanoparticles (TA-CDs-Cu2+) synthesized by introducing TA-CDs at room temperature. The TA-CDs-Cu2+ can be firmly anchored...
Twisted and coiled actuators (TCAs) are a type of thermal-driven actuator with high energy density display the enormous application potential to drive soft robots. However, existing robots driven by TCAs scarce can only realize grabbing creeping movement almost without load capacity. The main reason is that TCA fabricated traditional self-coiling method has low force long thermal response time. Aiming improve output TCA, fabrication enhancement principle multitwisted (MTCAs) developed....
Aiming at the potato cropping pattern in hilly area of southwest China, a small digging device for harvester was designed. First, overall structure determined according to soil physical characteristic and test site. Then, shovel, key components were designed analyzed relationship between inclination shovel power loss under conditions different speed, depth bulk density by MATLAB software, mathematical models established. Finally, three-dimensional model whole machine established SolidWorks,...
Infected chronic wounds, in particular, diabetic are hard to heal, posing a global health concern with high morbidity and mortality rates. Diabetic full-thickness wounds infected E. coli belong the most difficult heal wounds. Here, we introduced tannic acid-modified silicon-based nanoparticles (TA-SiNPs) broad-spectrum bactericidal activity that bacteria develop minimal resistance to, they can effectively treat mice coli. Our findings indicate these TA-SiNPs could achieve 100% antibacterial...
The development of biomass-based composites has greatly reduced the daily consumption plastics. However, these materials are rarely recyclable, thus, posing a severe threat to environment. Herein, we designed and prepared novel composite with ultra-high biomass (i.e., wood flour) filling capacity good closed-loop recycling properties. dynamic polyurethane polymer was polymerized in situ on surface fiber, then they were hot-pressed into composites. Fourier-transform infrared (FTIR), scanning...
In this work, titanium dioxide (TiO2)-incorporated rice straw fiber (RS)/poly(butylene succinate) (PBS) biocomposites were prepared by injection molding with different TiO2 powder loadings. The RS/PBS 1 wt% demonstrated the best mechanical properties, where flexural strength and modulus increased 30.34% 28.39%, respectively, compared RS/PBS. non-isothermal crystallization of neat PBS, composites, titanium-dioxide-incorporated composites was investigated differential scanning calorimetry...
Dynamic covalent networks exhibit intriguing reprocessing and self-healing properties, but they usually require complex synthesis procedures frequently use hazardous solvents. Herein, we proposed a green strategy for dynamic polyurethane that was conducted in one-pot, solvent-free manner addresses the aforementioned problems. A new type of low-transition-temperature mixture (LTTM) prepared by blending pyrogallol poly(ethylene glycol), which allowed reagents to remain as liquids at room...
The vibration isolation system is now indispensable to high-precision instruments and equipment, which can provide a low environment ensure performance. However, the disturbance with variable frequency poses challenge system, resulting in precision reduction of dynamic modeling. This paper presents velocity self-sensing method experimental verification system. A actuator designed isolate varying frequencies according absorber structure. mechanical structure illustrated, model derived. Then...
A novel Filippov forest‐pest system with threshold policy control (TPC) is established while an economic (ET) used to guide switching. The aim of our work address how reasonably and successfully pests by means sliding dynamics for the system. On basis above considerations, conditions existence stability equilibria subsystems are addressed, segments several types proposed defined. These include regular/virtual equilibrium, pseudoequilibrium, boundary tangent point. Further, not only relations...
Soft robots made from soft materials can safely interact with humans and environments compared the traditional rigid robots. However, inherent compliance of makes them difficult to realize jumping motion. Although many jump through design bistable structure. existing need spine be embedded in body. Therefore, it is still hard for a robot pure This paper offers method ability. The critical buckling force total elastic potential energy increased by designing body different thickness. We use...
Abstract Wood with a porous structure is the best carrier for phase change energy storage materials, which can effectively prevent material leakage during thermal cycling and ensure its shaping effect.
