We present a laser architecture to obtain continuous-wave (CW) light sources at the 589 nm sodium D2 line. A 808 diode-pumped Nd:YLiF4 (Nd:YLF) crystal emitting 1053 nm. part of pump power was then absorbed by Nd:YLF crystal. The remaining used Nd:YAG 1338 Intracavity sum-frequency mixing and realized in LiB3O5 (LBO) reach yellow-orange radiation. obtained CW output 235 mW with diode 17.8 W

Ankaflavin (AK) is a typical yellow pigment extracted from Monascus-fermented rice with several biological effects; however, its solubility poor. Thus, research studies of the delivery systems AK, especially those constructed protein-polysaccharide complexes, have attracted considerable attention. However, interactions that exist in system rarely been investigated. This work focused on between AK and bovine serum albumin (BSA) as well influence carrageenan (Car) binding to BSA. Results...
Time series analysis is based on the continuous regularity of development objective things to predict next value depending observed values. Based time analysis, we present autoregressive moving average models future for an uncertain series. In this paper, imprecise observations and disturbance terms are regarded as variables assume that latter satisfied normal distribution. The prediction established combining knowledge model uncertainty theory. Therefore, interval range predicted...
Tumor necrosis factor-α-inducing protein (Tipα) is a newly identified toxin that promotes the inflammation and carcinogenesis caused by Helicobacter pylori. However, its mechanism of pathogenesis still unclear. To investigate carcinogenic mechanisms Tipα, SGC7901 cells SGC7901-derived cancer stem-like (CSCs) were stimulated recombinant Tipα with or without Wnt/β-catenin signaling inhibitor XAV939. qRT-PCR Western blotting employed to detect expression epithelial-mesenchymal transition (EMT),...
Agricultural product trade openness is a crucial factor impacting agricultural carbon emissions. This study analyzes the relationship between and emissions in China. Using panel data from 2002 to 2020 for 31 provinces, threshold model employed examine non-linear an environmental regulation perspective. The findings reveal significant single-threshold effect of regulation. When intensity low, positively associated with However, when high, significantly reduces Regional regression analysis...
In this work, we focus on overcoming the challenge of a snake robot climbing outside bifurcated pipe. Inspired by postures biological snakes, propose an S-shaped rolling gait designed using curve transformations. For gait, robot's body presenting is wrapped mainly around one side pipe, which leaves space for fork To overcome difficulty in constructing and clarifying curve, present method establishing transformation between plane 3D cylindrical surface. Therefore, can intuitively design...
Misfolding and amyloid fibrillogenesis of proteins have close relationships with several neurodegenerative diseases. The present work investigates the inhibitive activities ankaflavin (AK) monascin (MS), two yellow pigments separated from
We report an efficient continuous-wave (CW) dual-wavelength operation of Nd:YAG (YAG: yttrium aluminum garnet) laser at 1319 and 1338 nm. An output power 2.47 W for the was achieved incident pump 16.7 W. Intracavity sum-frequency mixing nm then realized in LBO (lithium triborate) crystal to reach red range.

<p>This paper presents a gait design method for snake robots fit non-smooth backbone curves. Introducing bending angles at the points where directions of tangent vectors curve changes discontinuously breaks restriction that left and right limits each point on fitting target shape robot must be same, which makes trunk simpler more convenient. The was utilized to gaits spanning motions between parallel intersecting bars. in both scenarios are demonstrated simulation validate...
Hand synergy from neuroscience provides an effective tool for anthropomorphic hands to realize versatile grasping with simple planning and control.
