We report a precision measurement of the parity-violating asymmetry $A_{PV}$ in elastic scattering longitudinally polarized electrons from $^{208}$Pb. measure $A_{PV}=550\pm 16 {\rm (stat)}\pm 8\ (syst)}$ parts per billion, leading to an extraction neutral weak form factor $F_W(Q^2 = 0.00616\ GeV}^2) 0.368 \pm 0.013$. Combined with our previous measurement, extracted neutron skin thickness is $R_n-R_p=0.283 0.071$~fm. The result also yields first significant direct interior density...
We report a precise measurement of the parity-violating (PV) asymmetry A_{PV} in elastic scattering longitudinally polarized electrons from ^{48}Ca. measure A_{PV}=2668±106(stat)±40(syst) parts per billion, leading to an extraction neutral weak form factor F_{W}(q=0.8733 fm^{-1})=0.1304±0.0052(stat)±0.0020(syst) and charge minus F_{ch}-F_{W}=0.0277±0.0055. The resulting neutron skin thickness R_{n}-R_{p}=0.121±0.026(exp)±0.024(model) fm is relatively thin yet consistent with many model...
We report precision determinations of the beam-normal single spin asymmetries (A_{n}) in elastic scattering 0.95 and 2.18 GeV electrons off ^{12}C, ^{40}Ca, ^{48}Ca, ^{208}Pb at very forward angles where most detailed theoretical calculations have been performed. The first measurements A_{n} for ^{40}Ca ^{48}Ca are found to be similar that consistent with expectations thus demonstrating validity nuclei Z≤20. also two new momentum transfers (Q^{2}) extending previous measurement. Our data...
We report a high precision measurement of electron beam polarization using Compton polarimetry. The was made in experimental Hall A at Jefferson Lab during the CREX experiment 2020. total uncertainty dP/P=0.36% achieved detecting back-scattered photons from scattering process. This is highest accuracy ever reported, surpassing ground-breaking SLAC Large Detector (SLD) polarimeter. Such reaches level required for future flagship measurements to be by MOLLER and SoLID experiments.
In order to ensure accuracy of positioning rescue drilling, studied over technical basis required for precise drilling location and confirmation method locating finished underground drill-hole surface hole. Put forward the formulating drilling-positioning scheme, Discussed finishing hole positioned by synthesis center determined total station with GPS RTK give demonstrates cases. Related studies indicated that mutual verification two or more methods above are key measures accuracy.
Objective To explore the model of human resource management in operating room.Method We investigated work intensity 25 nurses room and took elastic scheduling to solve problem shortage resources.Results There was statistically significant difference outstanding rate nurses' overall performance rating between experimental group control (P =0.042).Quality care optimization mode April improved compared with conventional March.There satisfaction surgeon anesthesiologist (x2 =12.028,P...
In traditional video surveillance systems, supervisors need to watch multiple images at the same time. Surveillance resources are scattered and huge, making it difficult browse them all extract useful information from in a timely manner. The splicing system can be used merge splice fuse different perspectives form whole image, which is convenient for personnel supervision. This article introduces multi-view system: consists of several cameras. Through GStreamer framework, streaming performed...
Indoor growing is a trend in agriculture the future. Using drones to replace manual monitoring and picking of fruits can save costs free up manpower. Achieving precise by requires strong indoor positioning capabilities, but complex environment orchards, using single sensor may produce data fluctuations. This project proposes method fuse depth camera UWB solve problem insufficient performance sensor: independently obtain UWB, use Kalman filter process noise, calculate fluctuations degree,...
