We utilized UV resonance Raman (UVRR) measurements and density functional theory (DFT) calculations to relate the AmII'p frequency to the psi angle. The AmII'p frequency shifts by approximately 25 cm(-1) as the psi angle is varied over allowed angles of the Pro peptide bond. The AmII'p frequency does not show any significant dependence on the phi dihedral angle. The conformation sensitivity of ...

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$ ...

The suppression of the $\psi$(2S) nuclear modification factor has been seen as a trademark signature final state effects in large collision systems for decades. In small systems, deviations from unity had attributed to cold matter until observation strong differential $p/d+$A collisions, which suggests presence effects. this paper, we present results J/$\psi$ and measurements dimuon decay chann...

PURPOSE To calculate the indirect costs of Patient Specific Instruments (PSI) based on an opportunity cost, cost of efforts and a supply chain cost model to compare PSI for value with conventional total knee arthroplasty (TKA). METHODS In 81 patients the total (direct+indirect) cost of PSI-assisted TKA was compared with conventional TKA. Surgical times and coronal mechanical alignment were me...

We characterized the hyperpolarization of the electrical potential profile of flounder intestinal cells that accompanies inhibition of NaCl cotransport. Several observations indicate that hyperpolarization of psi a and psi b (delta psi a,b) results from inhibition of NaCl entry across the apical membrane: (a) the response was elicited by replacement of mucosal solution Cl or Na by nontransporte...

PSI is a large protein-pigment complex located in the thylakoid membrane in cyanobacteria, plants, and algae. Although the structure and components of PSI are well characterized, mechanisms that orchestrate its assembly are poorly understood. In this study, we discovered a novel nucleus-encoded protein, Photosystem I Assembly3 (PSA3), that is required for PSI accumulation. PSA3 is conserved amo...

The water relations parameters involved in assimilate flow into developing wheat (Triticum aestivum L.) grains were measured at several points from the flag leaf to the endosperm cavity in normally watered (Psi approximately -0.3 MPa) and water-stressed plants (Psi approximately -2 MPa). These included direct measurement of sieve tube turgor and several independent approaches to the measurement...

An isolated "native" photosystem I (PSI complex) contains three spectral populations of chlorophyll a antennae (Mullet, Burke, Arntzen 1980 Plant Physiol 65: 814-822). It was hypothesized that nearly one-half of these antennae ( approximately 45 Chl/P(700)) are associated with polypeptides of 21,500 to 24,500 daltons. The present study utilizes two developmental systems to verify this associati...

The photosynthetic sensitivity to high light differs among understory plants of shade- and sun- established tree species. Shade-established tree species are sensitive to high light but the underlying photosynthetic mechanism has not been fully resolved. In the present study, we examined the responses of photosystem I (PSI) and photosystem II (PSII) to high light in shade leaves of a shade-estab...
