Recently, the BESIII Collaboration published Born cross section of $e^+e^- \to K^+K^- J/\psi$, in which a new vector enhancement structure $Y(4500)$ was observed for first time. The mass resonance is good agreement with our previous prediction $5S$-$4D$ mixing charmonium candidate $\psi(4500)$, while measured width $2\sigma$ larger than theoretical estimate. In this work, we reanalyzed J/\psi$ ...

Overproduction or deficiency of many chaperones and other cellular components cure the yeast prions [PSI+] (formed by Sup35p) or [URE3] (based on Ure2p). However, at normal expression levels, Btn2p and Cur1p eliminate most newly arising [URE3] variants but do not cure [PSI+], even after overexpression. Deficiency or overproduction of Hsp104 cures the [PSI+] prion. Hsp104 deficiency curing is a ...

Plant photosynthesis and photosystem II (PSII) are susceptible to high temperature. However, photosynthetic electron transport process under heat stress remains unclear. To reveal this issue, chlorophyll a fluorescence and modulated 820 nm reflection were simultaneously detected in sweet sorghum. At 43°C, J step in the chlorophyll a fluorescence transient was significantly elevated, suggesting ...

Three new proteins which inhibit protein synthesis in rabbit reticulocyte lysates were isolated from an extract of sponge gourd (Luffa cylindrica) seeds by chromatography on a AF-Blue Toyopearl column followed by FPLC with a Mono S column. These three protein-synthesis inhibitory proteins (PSIs) have molecular masses of 19 kDa, 15 kDa, and 9 kDa, and were designated 19K-PSI, 15K-PSI, and 9K-PSI...

When startled adult D. melanogaster react by jumping into the air and flying away. In many invertebrate species, including D. melanogaster, the "escape" (or "startle") response during the adult stage is mediated by the multi-component neuronal circuit called the Giant Fiber System (GFS). The comparative large size of the neurons, their distinctive morphology and simple connectivity make the GFS...

Pseudouridine (5-ribosyluracil) is a ubiquitous yet enigmatic constituent of structural RNAs (transfer, ribosomal, small nuclear, and small nucleolar). Although pseudouridine (psi) was the first modified nucleoside to be discovered in RNA, and is the most abundant, its biosynthesis and biological roles have remained poorly understood since its identification as a "fifth nucleoside" in RNA. Rece...

THE elastic and mechanical properties of dentin were studied as early as 1895 by Black' who measured the compressive strengths of cubes of dentin and reported that a cube, 0.08 inch square, had an average compressive strength of 37,200 psi and an elastic deformation of 2.09 per cent when subjected to a load of 100 pounds (elastic modulus 0.8 x106 psi). Peyton, Mahler, and Hershenov2 reported av...

We define tropical Psi-classes on M 0,n (R 2 , d) and consider intersection products of Psi-classes and pull-backs of evaluations on this space. We show a certain WDVV equation which is sufficient to prove that tropical numbers of curves satisfying certain Psi-and evaluation conditions are equal to the corresponding classical numbers. We present an algorithm that generalizes Mikhalkin's lattice...

Seven zinc oxide-eugenol cements with compressive strengths from 200 psi to 8,000 psi were used for temporarily cementing completed inlays, crowns, and bridges. The effectiveness of each cement in a variety of clinical situations is presented. Cement of 1,000 psi met the requirements of typical clinical cases most frequently. The cements of compressive strength 200, 400, 600, 2,200, and 3,500 p...
