1Particle manipulation beyond the diffraction limit using structured super-oscillating light beams显示文摘The diffraction-limited resolution of light focused by a lens was derived in 1873 by Ernst Abbe.Later in 1952,a method to reach sub-diffraction light spots was proposed by modulating the wavefront of the focused beam.In a related development,super-oscillating functions,that is,band-limited functions that locally oscillate faster than their highest Fourier component,were introduced and experimentally applied for super-resolution microscopy.Up till now,only simple Gaussian-like sub-diffraction spots were used.Here we show that the amplitude and phase profile of these sub-diffraction spots can be arbitrarily controlled.In particular,we utilize Hermite–Gauss,Laguerre–Gauss and Airy functions to structure super-oscillating beams with subdiffraction lobes.These structured beams are then used for high-resolution trapping and manipulation of nanometer-sized particles.The trapping potential provides unprecedented localization accuracy and stiffness,significantly exceeding those provided by standard diffraction-limited beams.Brijesh K Singh Harel Nagar Yael Roichman Ady Arie 2017Light(Science & Applications)2017,6,1:5
2何种要求是为权利?——权利与理由关系的探究显示文摘一、导论言论自由经常与保护国家安全相冲突,前者传统上被划归为是一项个人权利,后者则是一项并非立基于权利(right-based)之上的重要关切(concern)。同样,正当程序、宗教自由以及平等保护被划归为个人权利,不受犯罪的侵害、公共秩序的维持、经济繁荣以及家庭价值的增进被划归为并非立基于权利之上的关切。[1]更为一般地说,有些要求(demands)被划归为权利,而其他有价值的要求却并未被划归为权利。Alon Harel 瞿郑龙(译) 张梦婉(译) 2013法理学论丛2013,,1:2
3Rubber plunger surface texturing for friction reduction in medical syringes显示文摘Friction is a genuine issue in the use of many medical devices involving rubbery materials such as plungers in medical syringes. This paper presents a new direction for the reduction of friction in medical syringes based on surface texturing of the rubber plunger. The specimens were prepared by casting poly(vinylsiloxane)(PVS) rubber into a pre-fabricated negative template obtained by 3D printing. Friction tests were performed on a home-made test-rig. It was clearly shown that friction resistance can be considerably manipulated when using textured plungers.Haytam KASEM Harel SHRIKI Lihi GANON Michael MIZRAHI Kareem ABD-RBO Abraham JDOMB 2019Friction2019,7,4:2
4Transverse approach between real world concentrations of SO_2, NO_2, BTEX, aldehyde emissions and corrosion in the Grand Mare tunnel显示文摘With regard to automotive traffic, a tunnel-type semi enclosed atmosphere is characterized by a higher concentration of gaseous pollutants than on urban traffic roads and highlights the gaseous effluent species having an impact on material degradation. Therefore, a transverse approach between air quality and its consequences upon the longevity of materials is necessary, implying better knowledge of tunnel atmosphere and a better understanding of material degradation inside a tunnel for operating administration. Gaseous pollutant measurements carried out in a road tunnel in Rouen (Normandy) give the real world traffic concentrations of experimental exposure conditions. The sampling campaigns, achieved in summer and winter include SO2, NO2, BTEX and aldehyde analyses. Effluent profiles in the upward and downward tubes have been established. The current work shows that SO2, NO2, formaldehyde, acetaldehyde, propanal and butanal must be considered in the degradation process of materials in a stuffy environment. As regards NO2, its concentration depends on the modification of the automotive fleet. The total aldehyde concentrations indicate no particular trend between the two bores. Formaldehyde, acetaldehyde, propanal, butanal and acrolein species are the most abundant species emitted by vehicles and represent 90% to 95% of the total aldehyde emissions.I. Ameur-Bouddabbous J.
