Quantum Key Distribution over 658 km Fiber with Distributed Vibration Sensing.

Twin-field quantum key distribution (TFQKD) promises ultralong secure key distribution which surpasses the rate distance limit and can reduce the number of the trusted nodes in long-haul quantum network. Tremendous efforts have been made toward implementation of TFQKD, among which, the secure key with finite size analysis can distribute more than 500 km in the lab and in the field. Here, we demonstrate the sending-or-not-sending TFQKD experimentally, achieving a secure key distribution with finite size analysis over a 658 km ultra-low-loss optical fiber.

[Acupoint selection rules of neurogenic dysphagia treated with acupuncture and moxibustion in ancient times].

Acupoint selection rules of neurogenic dysphagia treated with acupuncture and moxibustion from pre-Qin to late Qing Dynasty in were analyzed based on data mining. The literature regarding acupuncture and moxibustion for neurogenic dysphagia was searched and screened according to the inclusion and exclusion criteria in (5th Edition), the prescriptions were extracted according to the principle of acupoint extraction.The SPSS 21.

Vibrationally resolved photoemissions of N (CΠ → BΠ) and CO (bΣ → aΠ) by low-energy electron impacts.

Vibrationally resolved photoemission spectra of the electronic-state transitions CΠ → BΠ of N and bΣ → aΠ of CO following low-energy electron impacts are measured with a crossed-beam experimental arrangement. The absolute cross sections of CΠ (ν') → BΠ (ν″) of N are presented for the vibrational state-to-state transitions (ν',ν″) = (0,0), (0,1), (1,0), (1,2), and (2,1). The excitation cross sections of the metastable state CΠ of N show the maxima at the electron-impact energies 14.

[Acupuncture for dysarthria: systematic review].

Objective: To systematically evaluate the clinical efficacy of acupuncture for dysarthria, and to explore the rules of acupoints selection for dysarthria.

Methods: The clinical randomized control trial literature regarding acupuncture for dysarthria published before January of 2018 were searched in databases, including CNKI, Wanfang, VIP, CBM, PubMed, Ebsco, Science Direct and Cochrane Library. The information of included studies was extract and the quality was assessed.

8-Prenylgenistein, a prenylated genistein derivative, exerted tissue selective osteoprotective effects in ovariectomized mice.

Our previous study reported that the osteogenic effects of 8-prenylgenistein (8PG) were more potent than its parent compound genistein. This study aimed to evaluate the osteoprotective effects of 8PG in ovariectomized (OVX) mice as well as to characterize its estrogenic effects in uterus. Mature OVX mice were treated with phytoestrogen-free diet containing 8PG or genistein.

Effect of the water fraction isolated from Fructus Ligustri Lucidi extract on bone metabolism via antagonizing a calcium-sensing receptor in experimental type 1 diabetic rats.

Our previous studies have demonstrated that the extract of Fructus Ligustri Lucidi (FLL) can maintain in vivo calcium homeostasis in aged and ovariectomized rats. This study was designed to elucidate the action of water fraction isolated from the FLL extract on bone metabolism and a calcium-sensing receptor (CaSR) in parathyroid glands and kidneys of diabetic rats. The streptozotocin-induced diabetic rats were treated with vehicle, FLL extract, and the water fraction (WF) isolated from the FLL extract for 4 weeks.

Deletion of Opg Leads to Increased Neovascularization and Expression of Inflammatory Cytokines in the Lumbar Intervertebral Disc of Mice.

Study Design: Neovascularization and expression of inflammatory cytokines were examined in Osteoprotegerin (Opg) knockout (KO) mice that show intervertebral disc (IVD) degeneration.

Objective: The aim of this study was to clarify the pathological changes in lumbar IVD degeneration in Opg KO mice.

Summary Of Background Data: Osteoporosis is a controversial risk factor for IVD degeneration.

[Application of PHILOS plate with injectable artificial bone for the treatment of proximal humeral fractures in elderly patients].

Objective: To investigate the clinical effects of PHILOS plate with injectable artificial bone for the treatment of proximal humeral fractures in elderly patients.

Methods: From March 2007 to March 2009,17 patients who suffered from proximal humeral fractures were retrospectively studied. There were 7 males, 10 females, with an average age of 71 years (ranged, 66 to 81 years).

Tertiary treatment of textile wastewater with combined media biological aerated filter (CMBAF) at different hydraulic loadings and dissolved oxygen concentrations.

An up-flow biological aerated filter packed with two layers media was employed for tertiary treatment of textile wastewater secondary effluent. Under steady state conditions, good performance of the reactor was achieved and the average COD, NH(4)(+)-N and total nitrogen (TN) in the effluent were 31, 2 and 8mg/L, respectively. For a fixed dissolved oxygen (DO) concentration, an increase of hydraulic loading resulted in a decrease in substrate removal.

WNT/beta-catenin pathway up-regulates Stat3 and converges on LIF to prevent differentiation of mouse embryonic stem cells.

Embryonic stem (ES) cells rely on growth factors provided by feeder cells or exogenously to maintain their pluripotency. In order to identify such factors, we have established sub-lines of STO feeder cells which exhibit variable ability in supporting ES cell self-renewal. Functional screening identifies WNT5A and WNT6 as STO cell-produced factors that potently inhibit ES cell differentiation in a serum-dependent manner.
