Gallate MOF membranes show great promise for efficient C2H4/C2H6 separation due to the ability precisely discriminate subtle difference in molecular cross-section size of C2H4 and C2H6. Nevertheless, it remains a huge challenge prepare high-performance gallate with optimized structure uncontrollable nucleation growth bulk solution, which leads poor on substrate surface. In this study, we facilely prepared Co-gallate showing unprecedented through development freezing contra-diffusion...
Prussian Blue (PB), which was first discovered as robust blue-colored pigment in the year 1706, has shown promising prospects disease treatment, energy conversion, water splitting, and sensing. Relying on uniform 3.2 Å-sized pore channels well high stability aqueous environments, this study, we pioneered situ preparation of polycrystalline PB membranes to justify their dye rejection metal ion discrimination ability environments. Among various factors, introduction calcined NiFe layered...
Malt is an important raw material in brewing beer. With the increasing development of craft beer, malt has contributed diverse colours and abundant flavours to While "malty" "worty" were commonly used describe flavour they are still inadequate. This study focused on developing a sensory lexicon wheel for malt. Here, total 22 samples evaluation. The panels identified 53 attributes form malt, including appearance, flavour, taste, mouthfeel. After consulting with experts from industry, 46...
Aims:Calling is an important way for birds to communicate and transmit information each other.This provides a unique opportunity assess bird diversity through acoustic monitoring.The use of indices the rapid assessment biodiversity emerging survey method, but complex sonic environment in urban forests may lead bias.The feasibility using still needs be further explored.Methods: To understand effectiveness forests, we set up 50 matrix sample sites Beijing Eastern Suburb Forest Park.Bird point...
This paper explores the relationship between Internet use, environmental risk perception, government performance and pro-environmental behaviors.Survey data from Chinese General Social Survey 2013 was used to test relevant hypotheses.The results show that: (1) use has significant positive effects on perception behaviors.(2) have negative public about government's performance.(3) Government a effect behaviors negatively mediates of behaviors.The findings suggest that increasing exposure can...
The production of anti-Her2 chimeric antigen receptor (CAR) T cells needs to be optimized make it a reliable therapy.Three types lentiviral vectors expressing CAR together with packaging plasmids were co-transfected into 293 T-17 cells. vector the best efficiency was selected, and cell culture system plasmid optimized. Centrifugation speed for concentration lentivirus stock. various purification methods used included membrane filtration, centrifugation sucrose cushion novelly-designed...
Fragrant rapeseed oils and traditional pressed are increasingly popular in China owing to their sensory advantages. Many fragrant labeled by different fragrance types; however, the scientific basis for these differences is lacking. To identify distinctive aroma achieve classification, characteristics components of nine were analyzed via evaluation gas-chromatography-mass spectrometry-olfactometry. A total 35 compounds found contribute overall aroma. By using chemometrics methods, categorized...
Background Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a common disorder. The lower atmospheric pressure and decreased oxygen levels of high-altitude areas can exacerbate the severity OSAHS, but research into OSAHS in remains limited. This study, from June 2015 to January 2020, involved 4,667 patients with suspected 38 healthy volunteers. non-OSAHS group (AHI <5/h) had 395 patients, while larger ≥5/h) comprised 4,272 patients. significant size difference between groups...
Abstract In this study, four typical fragrance types of rapeseed oils were investigated under short-term frying French fries and heating processes. Volatile flavor profiles, aroma compounds, sensory attributes evaluated by gas chromatography–mass spectrometry (GC-MS), chromatography–olfactory (GC-O), evaluation. The examination showed 140 volatiles, 28 as well 8 detected. Aldehydes, nitriles, acids principal groups in unheated delicate oil (DFRO) refined (RRO), acids, heterocycles strong...

回帰分析は統計的データ解析の本流を成し,多くの分野で適用されている.回帰関数としては通常単一の滑らかな関数を考えることが多いが,回帰関数がある点を境に折れ曲がっているように見えることがある.そのような場合は,回帰関数として単一の関数を想定するよりも,独立変数に2つの相があり,各相で異なる回帰関数を当てはめる方が自然であろう.本論文では回帰関数として1次式を考え,単純直線回帰を帰無仮説,ある未知の点(変化点)を境にして連続ではあるが折れ曲がった2相直線回帰を対立仮説とした検定問題に対する尤度比検定を考える.この場合,検定統計量の厳密分布を求めることは現実には困難であり,漸近的にも標準の漸近理論の仮定が成立せず,したがって対数尤度比検定統計量にカイ2乗近似を用いることができない.この点に関し多くの研究者により様々な議論が展開されてきたが,現在のところ実用的な結論は得られていない.本論文ではそれらの議論を検証し,尤度比検定統計量の実用に耐える近似帰無分布を導いた.さらに,誤差分散の大きさ,独立変数の配置により帰無分布がどう変わるか,また検出力がどう変わるかを調べ,棄却点が分散の大きさに...
The application of sodium laser guide star is the key difference between modern adaptive optics system and traditional system. Especially in like multi-conjugate optics, asterism which formed by several stars certain pattern required to probe more atmospheric turbulence different directions. To achieve this, a launching platform required. In this paper, we will introduce built tested on 1.8m telescope Gaomeigu Observatory. has two functions: one compare performance generated lasers at same...
