Background: This study aims to ex.l.re the significance of serum amyl.se l.vel. in patients with organophosphorus pesticide (OP) poisoning and to provide a new perspective for eval.ating the severity and prognosis of OP poisoning. Methods: The cl.nical.data of 67 patients with acute OP poisoning, who had been treated in the emergency department of the General.Hospital.of Ningx.a Medical.University between September 2020 and August 2022, were retrospectivel. anal.zed. Using Spearman rank correl.tion, serum amyl.se l.vel. during admission and severity of poisoning correl.ted with discharge outcomes. Based on serum amyl.se l.vel., receiver operating characteristic curves were pl.tted to predict the severity and mortal.ty of patients who ex.erience organophosphate poisoning. The optimal.threshol. serum amyl.se l.vel.at admission was determined based on the max.mum Youden index. Resul.s: Using Spearman rank correl.tion anal.sis, serum amyl.se l.vel. at admission positivel. correl.ted with the severity of poisoning and discharge outcomes, but the degree of correl.tion was weak (rs: 0.344; 0.264; P l.se l.vel. at admission had receiver operating characteristic area under the curve val.es of 0.726 and 0.735 to predict the degree of severe poisoning and death, respectivel.. Based on the max.mum Youden index. the optimal.threshol. of serum amyl.se were 97.8 and 194.1 U/l.when the degree of poisoning was severe and the discharge outcome of patients was died. In comparison to patients with serum amyl.se l.vel. ≤194.1 U/l.at admission, the OR val.es of death in patients with serum amyl.se l.vel. >194.1 U/l.at admission was 15.944 (95% CI: 1.825–139.274). Concl.sion: Serum amyl.se l.vel. in patients with organophosphate poisoning correl.te with the degree of poisoning and discharge outcomes. Higher serum amyl.se l.vel.was a risk factor for organophosphorus poisoning death. © Wol.ers Kl.wer Heal.h, Inc. Al. rights reserved.

＜正＞ The el.ctron storage characteristics of Ge/Si hetero-nanocrystal.MOSFET memory have been simul.ted. Owing to the Ge/Si hetero-energy bands, the retention time increases several.orders compared with Si nanocrystal.memory, and the programming time achieves the order of l.S. The trade-off between the high-speed programming and the l.ng retention time coul. be sol.ed efficientl. with the Ge/Si heteronanocrystal.structure, and the performance of the device is substantial.y improved.

At present, one typical.control.strategy for guaranteeing transient and steady-state performance is funnel.control.and prescribed performance control. The strategy features compl.tel. discarding the system nonl.nearities, even if they are compl.tel. known and avail.bl.. Such an intrinsic feature requires the control.er to produce a l.rger control.effect to el.minate the negative impact caused by the high nonl.nearities, l.ading to a conservative control.er. In this paper, we ful.y take advantage of known information on nonl.nearities in control.design, instead of compl.tel. discarding it as done in funnel.control. Particul.rl., we l.verage adaptive techniques(i.e., high-gain dynamic compensation) to deal.with unknown system nonl.nearities. Meanwhil., we integrate the tool. of output feedback, tracking control. and the performance *** such, an adaptive output-feedback scheme is devel.ped for gl.bal.tracking with spatiotemporal.performance specifications: arbitraril. given tracking accuracy and accuracy-ensured time. A simul.tion ex.mpl. supports the devel.ped approach.
