Blood lactate concentration is an established circulating biomarker for measuring muscle acidity and can be evaluated monitoring endurance, training routines, or athletic performance. Sweat alternative biofluid that may serve similar purposes offers the advantage of noninvasive collection continuous monitoring. The relationship between blood dynamic sweat biochemistry wearable engineering applications in physiological fitness remains poorly defined. Here, we developed a microfluidic band...
Abstract The earth's hydroclimate is continuing to change, and the corresponding impacts on water resource space‐time distribution need be understood mitigate their socioeconomic consequences. A variety of ecosystem services, transport processes, human activities are synced with timing peak annual runoff. To understand influence changing runoff dates across continental United States, we downscaled outputs 10 Global Circulation Models for different future scenarios. Our results quantify...
Competition for nitrogen (N), particularly in resource-limited habitats, might be avoided by different N acquisition strategies of plants. In our study, we investigated whether slow-growing European beech and fast-growing sycamore maple seedlings avoid competition growth-limiting uptake patterns the potential alteration soil availability a microcosm experiment. We quantified growth biomass indices, (15)N capacity pools fine roots. Overall, roots were influenced species-specific depending on...
This article is related to the coordinated formation control of multiple unmanned aerial vehicles (UAVs) with confined communication resources under a path-following context. To fulfill path following without any temporal limitations, an individual robust heading law derived for UAVs approximate predefined orbit characterized by implicit functions free from operational times, whereas concise and computationally efficient observation option, i.e., unknown system dynamics estimator (USDE)...
A novel high- speed image super-resolution algorithm based on sparse representation for MEMS defect detection is proposed in this paper. Traditional algorithms adopt a single dictionary to represent images, which cannot differentiate varieties of blocks and leads slow processing speed. Aiming at overcoming shortage traditional algorithms, are divided into different categories by local features each these possesses the corresponding high low resolution pairs. Experimental results defects show...
This paper presents a hybrid unscented particle filter (UPF) based on the firefly algorithm for tightly-coupled stereo visual-inertial vehicle positioning systems (VIVPS). Compared with standard UPF, this novel approach can achieve similar estimation accuracy much less computational complexity. To reduce complexity, time updating of Kalman is conducted via formula linear basis constructed linear/nonlinear mixed model. The optimised by modified to number particles needed means moving towards...
Abstract Based on the system coupling mechanism, a three-system model of energy, economy and environment is constructed. panel data Hebei Province from 2010 to 2019, empirical analysis development status three systems in Province. The results show that degree generally shows an upward trend, consistent with coordination energy-economy, energy-environment economy-environment. coordinated each binary basic guarantee for increase ternary system.
The use of nanometre fiso interferometer to measure heterodyne interference signals at the same time for phase and element detection phase-locked frequency multiplication counting is employed here. After a certain logic mixing, set measurement results with degree redundancy can be obtained; test measured resolved. rate better than 0.1 nm, range not limited by λ/2 period, thus overcoming previous problems that method one period resolution easy improve.
In the context of geographical "emotional turn", urban leisure began to pay attention locality reflected by subject and "human-land relationship" city.This study takes Xi'an cricket fighting as an example, analyzes coupling relationship between this style local time space interpreting cognitive system map leisure, using GIS analysis in-depth interviews.It also reveals spatial attributes, meaning, spiritual functions from three levels: material, social, spiritual.The conclusions show that:...

A cycled generative adversarial network to obtain high-quality loss via forcing the forward and backward half-cycle output consistent estimation. Moreover, gradient-based perceptual are introduced eliminate interference of complex photometric change on To solve ill-posed problem depth estimation, multi-task learning aided estimation module based strong...
A polydimethylsiloxane-coated Mach–Zehnder interferometer combined with a tilted fiber Bragg grating is proposed and experimentally evaluated for temperature refractive index measurements of liquids. The average sensitivity the sensor can reach 4.88, 5.15, 4.53, 4.38 nm/°C in ranges 20, 30, 40, 50 °C, respectively. range 1.3330–1.3614, sensing 521.92 nm/RIU. Comparisons other optic interferometers show that has attractive application prospects owing to its simple fabrication, compactness,...
In this work, the electromagnetic properties of Ni0.22Cu0.31Zn0.47Fe2O4 (NiCuZn) ferrites doped with 0.3 wt% Bi2O3 + x CuO flux (x = 0.2, 0.4, 0.6, and 0.8 wt%) were studied. Doping resulted in a reduction sintering temperature to 900 ℃. The synthesized via solid-state method. XRD reveal that prepared have cubic spinel structure; thus, moderate addition does not change crystal structure. SEM images as well density grain size distribution samples show NiCuZn densified, homogenized, contain...
An efficient forecasting algorithm on burst transmission probability is proposed in this paper. This new based the self-similarity characteristics of traffic. Firstly, tests by evaluating Hurst index according to graphical R/S analysis. Secondly, adopts Pareto distribution analyze transmitted probability. Because convenient and economical considerations, analysis groups data OFF time periods. Simulation results show can estimate simply efficiently.
