Passive Continuous Variable Measurement-Device-Independent Quantum Key Distribution Predictable with Machine Learning in Oceanic Turbulence.

Building an underwater quantum network is necessary for various applications such as ocean exploration, environmental monitoring, and national defense. Motivated by characteristics of the oceanic turbulence channel, we suggest a machine learning approach to predicting the channel characteristics of continuous variable (CV) quantum key distribution (QKD) in challenging seawater environments. We consider the passive continuous variable (CV) measurement-device-independent (MDI) QKD in oceanic scenarios, since the passive-state preparation scheme offers simpler linear elements for preparation, resulting in reduced interaction with the practical environment.

Propofol combined with alfentanil for general anesthesia in vocal cord polypectomy under suspension laryngoscopy.

Objective: To investigate the clinical effect of propofol combined with alfentanil in vocal cord polypectomy under suspension laryngoscopy.

Methods: A total of 308 patients undergoing vocal cord polypectomy under suspension laryngoscopy in the First Affiliated Hospital of Nanchang University were included in this prospective study, and the patients were randomly divided into an observation group and a control group. Patients in the observation group received alfentanil combined with propofol, while those in the control group were anesthetized with sufentanil combined with propofol.

Remimazolam benzenesulfonate anesthesia effectiveness in cardiac surgery patients under general anesthesia.

Background: Sedation with propofol injections is associated with a risk of addiction, but remimazolam benzenesulfonate is a comparable anesthetic with a short elimination half-life and independence from cell P450 enzyme metabolism. Compared to remimazolam, remimazolam benzenesulfonate has a faster effect, is more quickly metabolized, produces inactive metabolites and has weak drug interactions. Thus, remimazolam benzenesulfonate has good effectiveness and safety for diagnostic and operational sedation.

First Report of Round Spot Disease of Zanthoxylum armatum DC Caused by Fusarium fujikuroi in China.

Zanthoxylum armatum DC, a deciduous tree in Rutaceae, has significant economic value as an important food condiment, spice, and medicine (Cao et al. 2019). Recently, an unknown round leaf spot disease has been found on Z.

A smart bottom-up strategy for fabrication of complex hydrogel constructs with 3D controllable geometric shapes through dynamic interfacial adhesion.

A novel and facile dynamic interfacial adhesion (DIA) strategy has been successfully applied in the reversible fabrication of complex 3D hydrogel constructs based on dynamic covalent bonds (DCBs). By tailoring the geometry of gel building blocks (GBBs) and incorporating stimuli-responsive units, various shapes could be easily achieved.

Methods: From November, 2009 to November, 2012, an 0. hupensis snail infested beach of the Yueyang jail and an O.

Biphasic recognition chiral extraction: A novel method for separation of mandelic acid enantiomers.

This article reports a new chiral separation method-biphasic recognition chiral extraction for the separation of mandelic acid enantiomers. Distribution behavior of mandelic acid enantiomers was studied in the extraction system with O,O'-di-benzoyl-(2S,3S)-4-toluoyl-tartaric acid (D-(+)-DTTA) in organic phase and beta-CD derivatives in aqueous phase, and the influence of the types and concentrations of extractants and pH on extraction efficiency was investigated. Hydroxypropyl-beta-cyclodextrin (HP-beta-CD), hydroxyethyl-beta-cyclodextrin (HE-beta-CD), and methyl-beta-cyclodextrin (Me-beta-CD) have stronger recognition abilities for S-mandelic acid than those for R-mandelic acid, among which HP-beta-CD has the strongest ability.
