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...

CO2 flooding plays a crucial role in enhancing oil recovery and achieving carbon reduction targets, particularly unconventional reservoirs with complex pore structures. The phase behavior of hydrocarbons at different scales significantly affects efficiency, yet its underlying mechanisms remain insufficiently understood. This study improves existing thermodynamic models by introducing Helmholtz free energy as convergence criterion incorporating adsorption effects micro- nano-scale pores....
Late extraluminal postpancreatectomy hemorrhage (LEPPH) is a rare but severe complication of pancreaticoduodenectomy (PD). Current predictors LEPPH are limited and cannot quantify bleeding risk. As consequence, establishment prediction model important. This study aims to construct nomogram combining perioperative factors predict LEPPH. A total 2,924 retrospective 467 prospective cases undergoing PD, 420 131 with postoperative pancreatic fistula (POPF) after PD from three centers were...
