A multiparty quantum secret sharing (MQSS) protocol with two-photon three-dimensional Bell states was proposed by Gao [Commun. Theor. Phys. 52 (2009) 421] recently. This study points out that the performance of Gao's protocol can be much improved by using the technique of decoy single photons and carefully modifying the protocol to remove some unnecessary unitary operations, devices, and transmissions.

Background: Despite many reports on the diagnostic yield of cytology from endoscopic ultrasound-guided fine-needle aspiration(EUS-FNA), inter-slide differences are unknown. This prospective study aimed to compare diagnostic yield and cellular characteristics of bottom slides(BS) and top slides(TS) from EUSFNA cytology performed without an on-site cytopathologist. Methods: In patients with suspected pancreatic cancer on previous imaging explorations, a single endoscopist performed EUS-FNA and obtained 2 sets of cytology slide(8 BS and 8 TS), 1 cellblock slide, and 1 biopsy slide. Both slide sets were randomly assigned. A cytopathologist with more than 10 years of expertise in pancreatic cytopathology blindly inspected and compared two slide sets. Results: In total, 73 specimens [42 head(57.5%), 16 body(21.9%), and 15 tail(20.5%)] were acquired for final analysis. Seventy-one cases were finally diagnosed with pancreatic cancer. The sensitivity and specificity of BS were 80.3% and 100.0%; and of TS 78.9% and 100.0%, respectively. In analyzing inter-slide difference, 66 cases(90.4%) showed consistent results between BS and TS. However, seven(9.6%) were positive only in one slide sets(4 BS and 3 TS). The proportions of specimens more than moderate and high cellularity were 75.3% and 60.3% in both slide sets( P > 0.99), and the proportion of artifact-free sets were 50.7%, and 52.1% for the BS and TS, respectively( P = 0.869). Conclusions: Although BS and TS exhibited highly consistent diagnostic yields in cytologic smears from EUS-FNA, the proportion of inter-slide discordance is clinically considerable. Both slide sets need to be examined if there is no on-site cytopathologist.

OBJECTIVE: To quantitatively evaluate the therapeutic effects of Red Liriope platyphylla(RLP) on atopic dermatitis(AD), alterations in the luciferase(Luc) signal and general phenotype biomarkers were compared in phthalic anhydride(PA) treated Interleukin-4(IL-4)/Luc/Consensus non-coding sequence-1(CNS-1) transgenic(Tg) mice following treatment with aqueous extract of RLP(AEt RLP) for4 ***: Alterations in AD phenotypes were measured in IL-4/Luc/CNS-1 Tg mice following treatment with AEt RLP using inflammation parameter analysis, bioluminescence imaging analysis, histological analysis, reverse transcription-polymerase chain reaction, enzyme linked immunosorbent assay and Western blot ***: RLP contained high concentrations of total phenolic compounds, total flavonoid compounds and 5-HNE related to AD therapy. The Luc signal was only detected in the abdominal region and the submandibular lymph node(SL), mesenteric lymph node(ML), thymus and pancreas of the PA treated group. This signal was significantly decreased by 28%-73% throughout the body and in the four organs in PA + AEt RLP treated group. Furthermore, the lymph node weight, immunoglobulin E concentration and dermal thickness were decreased by 37%-67% in the PA + AEt RLP treated ***: Our findings suggest that the therapeutic effect of AEt RLP on PA induced AD could be successfully quantified by comparison of Luc signals and AD phenotype markers in IL-4/Luc/CNS-1Tg mice, and that the Luc signal was as sensitive as the general AD phenotypes, enabling detection of effects without euthanasia.

This study examines how the complex flow structure within a gas turbine rotor affects aerodynamic loss. An unshrouded linear turbine cascade was built, and velocity and pressure fields were measured using a 5-hole probe. In order to elucidate the effect of tip clearance, the overall aerodynamic loss was evaluated by varying the tip clearance and examining the total pressure field for each case. The tip clearance was varied from 0% to 4.2% of blade span and the chord length based Reynolds number was fixed at 2×10^(5). For the case without tip clearance, a wake downstream of the blade trailing edge is observed, along with hub and tip passage vortices. These flow structures result in profile loss at the center of the blade span, and passage vortex related losses towards the hub and tip. As the tip clearance increases, a tip leakage vortex is formed, and it becomes stronger and eventually alters the tip passage vortex. Because of the interference of the secondary tip leakage flow with the main flow, the streamwise velocity decreases while the total pressure loss increases significantly by tenfold in the last 30% blade span region towards the tip for the 4.2% tip clearance case. It was additionally observed that the overall aerodynamic loss increases linearly with tip clearance.

Guard cells are specialized cells forming stomatal pores at the leaf surface for gas exchanges between the plant and the atmosphere. Stomata have been shown to playan important role in plant defense as a part of the innate immune response. Plants actively close their stomata upon contact with microbes, thereby preventing pathogen entry into the leaves and the subsequent colonization of host tissues. In this review, we present current knowledge of molecular mechanisms and signaling pathways implicated in stomatal defenses, with particular emphasis on plant-bacteria interactions. Stomatal defense responses begin from the perception of pathogen-associated molecular patterns （PAMPs） and activate a signaling cascade involving the production of secondary messengers such as reactive oxygen species, nitric oxide, and calcium for the regulation of plasma membrane ion channels. The analyses on downstream molecular mechanisms implicated in PAMP-triggered stomatal closure have revealed extensive interplays among the components regulating hormonal signaling pathways. We also discuss the strategies deployed by pathogenic bacteria to counteract stomatal immunity through the example of the phytotoxin coronatine.
