Circular Dichroism (CD) of the phenyl- and phenyl-1-thio-β(or α)--glycosides were studied. The sign and the rotational strength of Band C, the shortest and the strongest band between 180~210 nm, were associated with the anomeric configuration and conformation in the same manner as the σ→σ* band of the ring oxygen in the 1-alkyl- and 1-alkyl-thio-glycosides. This result suggested that the could be extended to the phenyl- and phenyl-1-thio-glycosides. 相似文献

An astigmatic method for focus error detection has been integrated into a singlet. The first convex and the second concave surfaces compose a telephoto system with a telephoto ratio of about 0.4. The first surface of the lens is rotationally symmetrical asphere and the second surface is a toric shape whose aspherical profiles correct spherical aberration. We implemented our optical design using a molded glass process. Its performance was confirmed using the optical head of a magneto-optical disk system. 相似文献

The mechanism and temporal characteristics of gloss perception are not entirely clear. In addition, the formulation for predicting
gloss perception from photometric values has not been established. In the present study, we conducted an experiment to measure
several temporal characteristics of gloss perception in order to clarify the mechanism. All stimuli were rendered as computer
graphics with Phong and Lambert models to provide gloss perception to human observers. We measured perceptual glossiness with
a magnitude estimation method and perceptual diffuse/specular reflectance of test stimuli with a matching method under several
stimulus conditions, such as reflectance coefficients and stimulus duration. The results showed that the perceptual specular
component and perceptual glossiness increase with decreasing stimulus duration. Finally, we proposed a formulation to predict
perceptual glossiness as a function of stimulus duration. 相似文献

We propose to utilize the leading pulse of a petawatt class laser to create a conic plasma channel in the dense plasmas. This plasma channel could serve as a natural cone to guide the main pulse to the cone tip, as behaves similarly to the physical Au cone. We estimate that the leading pulse of a petawatt laser could create a natural cone with cone tip only about 100 μm away from the edge of compressed core plasma. The natural cone formation should be compatible for a good uniform compression and efficient fast heating of the imploded fuel. 相似文献

The direct sum \({{\mathcal O}_{*}}\) of all Cuntz algebras has a non-cocommutative comultiplication \({\Delta_{\varphi}}\) such that there exists no antipode of any dense subbialgebra of the C*-bialgebra \({({\mathcal O}_{*},\Delta_{\varphi})}\). From states equations of \({{\mathcal O}_{*}}\) with respect to the tensor product, we construct an operator W for \({({\mathcal O}_{*},\Delta_{\varphi})}\) such that W* is an isometry, \({W(x\otimes I)W^{*}=\Delta_{\varphi}(x)}\) for each \({x\in {\mathcal O}_{*}}\) and W satisfies the pentagon equation. 相似文献

Objective: To derive a clinical prediction rule for early recovery of knee range of motion after total knee arthroplasty. Methods: This prospective cohort study evaluated the data of 273 individuals undergoing primary total knee arthroplasty. The individual factors, the physical and motor function data were assessed preoperatively upon admission as a baseline survey. The knee joint extension angle and knee joint flexion angle were re-evaluated on postoperative day 14 as a follow-up. The recovery group comprised individuals with a knee joint extension angle of more than -5 degrees and knee joint flexion angle of more than 110 degrees on postoperative day 14. The other patients constituted the non-recovery group. Multivariate logistic regression analysis was used for deriving a clinical prediction rule. Results: The results indicated that the use of a cane, knee joint extension and flexion angles, and Timed Up and Go test time were significant factors for predicting early recovery of knee range of motion after total knee arthroplasty. Furthermore, a clinical prediction rule was derived and included the use of a cane, knee joint extension angle ≥ -15 degrees, knee joint flexion angle ≥ 125 degrees, and a Timed Up and Go test time < 11.2 s. A total clinical prediction rule score ≥ 8 indicated a positive likelihood ratio of more than 10 for a successful outcome and the post-test probability was approximately 95%. Conclusions: The derived clinical prediction rule might be a useful screening tool for proper postoperative goal setting and the establishment of individualized physical therapy programs. 相似文献

Two krypton-chloride germicidal excimer lamp units (Care222 TRT-104C11-UI-U3, USHIO Inc.) were installed in the examination room of an ophthalmology department. The irradiation dose was set not to exceed the former (i.e., before 2022) threshold limit value (TLV) (22 mJ cm−2/8 h) recommended by the ACGIH. Section 1: The eyes and lids of the six ophthalmologists (5 wore glasses for myopic correction) who worked in the room for a mean stay of 6.7 h week−1 were prospectively observed for 12 months. Slitlamp examinations revealed neither acute adverse events such as corneal erosion, conjunctival hyperemia, and lid skin erythema nor chronic adverse events such as pterygium, cataract, or lid tumor. The visual acuity, refractive error, and corneal endothelial cell density remained unchanged during the study. Section 2: The irradiation of samples placed on the table or floor using the same fixtures in the room (5–7.5 mJ cm−2) was associated with >99% inhibition of φX174 phage and >90% inhibition of Staphylococcus aureus. In conclusion, no acute or chronic health effects in human participants was observed in a clinical setting of full-room ultraviolet germicidal irradiation by 222-nm lamp units, and high efficacy in deactivation of microorganisms was determined in the same setting. 相似文献
