A novel PNIPAm/PNAGA double-network hydrogel based on a self-assembly cross-linking strategy was prepared for the first time. Due to existence of various hydrogen bonds, exhibits wide and adjustable dual temperature-sensitive behavior LCST-type UCST-type, highly stretchable, healable properties, which indicated great potential applications in simulation human skin monitor ambient temperatures.

In order to enable full participation of high-performance units controlled by different dispatching centers in the performance-based frequency regulation market, a data-driven grid-area coordinated load control (GAC-LFC) strategy using unified market mechanism is proposed. The takes into account coordination LFC controllers areas interconnected power grid, and accommodates large number secondary regulation. addition, an effective exploration-based multi-agent deep deterministic policy...

Adipose-derived mesenchymal stem cell-derived small extracellular vesicles (Ad-MSC-sEVs/AMEs) combined with scaffold materials are used in tissue-engineered bladders; however, the lack of retention leads to limited distribution AMEs areas and low bioavailability after bladder reconstruction. To improve AMEs, we developed a novel strategy that modifies surface charge acellular matrix (BAM) via oxidative self-polymerization dopamine-reducing graphene oxide (GO) using...

Abstract A preliminary experimental evaluation of duration load and creep effects lightweight wood-strand sandwich panels (lwW-SSP) was conducted following ASTM D6815-09 to determine the equivalence visually graded lumber as specified in Practice D245. The modulus rupture (MOR) lwW-SSP obtained using four-point bending tests evaluate their behavior at three stress levels (15, 40 65% MOR). Two different widths were considered observe effect this parameter. preformed well under long-term...

A microfiber Mach-Zehnder interferometer (MMZI) with two spindle-shaped structures was reported for measuring temperature and curvature. Due to the core-separated structure, MMZI could excite more high-order modes, which improves sensitivity efficiently. When central waist region is 4 μm, sensitivities curvature were 1290.4pm /°C 56.1947 nm/m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> , respectively.

To achieve a high operation efficiency and control performance of proton exchange membrane fuel cell (PEMFC), multi-objective optimal fractional-order proportion integration differentiation (FOPID) controller is proposed to maintain the oxygen excess ratio (OER) output voltage at reference value simultaneously. In addition, novel large-scale deep reinforcement learning called demonstration curriculum strategy multi-delay deterministic policy gradient (DCSL-MD3PG) algorithm designed operate...

Bazhen is a classic prescription used for the prevention of qi and blood deficiency. The present study aimed to investigate effects dietary supplementation with modified powder (MBP) on sows during lactation. Forty pure-bred Yorkshire day 100 gestation were randomly fed standard diet supplemented 20 g MBP per sow (MBP group) or without (control -14 7 days relative parturition. Results showed that serum levels interleukin 2 (IL-2), immunoglobulin A (IgA), IgG higher, whereas IL-10 level was...

Distributions of angles departure (AODs) and arrival (AOAs) are essential for mobile communications since they the basis channel modeling, estimation, antenna beamforming, precoding, positioning. However, distributions AODs AOAs air-to-air (A2A) have not been presented precisely, to mention time-variant probability density functions (PDFs). This letter presents analytical derivations PDFs ground scattering paths over open area based on uniformly distributed scatterers in maximum delay...
