Temporal jitter in a magnetic pulse compression based copper vapor laser (CVL) system is analyzed by considering ripple present in the input dc power supply and ripple present in the magnetic core resetting power supply. It is shown that the jitter is a function of the ratio of operating voltage to the designed voltage, percentage ripple, and the total propagation delay of the magnetic pulse compression circuit. Experimental results from a CVL system operating at a repetition rate of 9 kHz are presented. 相似文献

A biosensor application of vertically coupled glass microring resonators with Q/spl sim/12 000 is introduced. Using balanced photodetection, very high signal to noise ratios, and thus high sensitivity to refractive index changes (limit of detection of 1.8/spl times/10/sup -5/ refractive index units), are achieved. Ellipsometry and X-ray photoelectron spectroscopy results indicate successful modification of biosensor surfaces. Experimental data obtained separately for a bulk change of refractive index of the medium and for avidin-biotin binding on the ring surface are reported. Excellent repeatability and close-to-complete surface regeneration after binding are experimentally demonstrated. 相似文献

Replies to comments made by G. E. Gignac (see record 2005-06671-010) on the current authors' original article (see record 2003-02341-015). Gignac reanalyzed the factor structure of the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) and found results that differed from those the authors obtained initially. The authors tracked down the surprising sources of those discrepancies. G. E. Gignac's hierarchical model of emotional intelligence appears promising, and the authors anticipate that further investigations of the MSCEIT factor structure may yield additional information.

Houses in multiple occupation (HMOs) in which tenants share facilities are housing an increasing proportion of vulnerable adults who have limited affordable housing options. However, knowledge about how these types of property are managed is limited. In this paper, we examine the governance function of HMO landlords from the perspective of landlords/landlord agents and the tenants that live within their properties. The landlord exercises control through formal and informal risk assessment of tenants and close surveillance of them. These control mechanisms may also involve direct or indirect provision of support and care to some tenants. This illustrates the complex relationship between care and control and the extent to which both are integral to the housing management of vulnerable tenants living in HMOs. We suggest that this dual function calls for a critical examination of what constitutes a ‘good landlord’. 相似文献

Abstract ‘The good is oft interred with their bones.’ Much of what has been written of William Henry Fox Talbot has done him meagre justice: criticism for patenting his inventions, accusations that he patented the ideas of others, denigration of the importance of his discoveries. Though acknowledged as a scientist, his place as an artistic worker in the medium he invented has not been appreciated. 相似文献

Copper solubility in low-k dielectrics has been shown to be a major factor in decreasing the useful lifetime of an interconnect.
A number of groups have shown experimentally that increased surface oxygen concentration, increased moisture content in the
dielectric, and an increase in interfacial copper concentration from chemical–mechanical polishing all contribute to accelerated
failure. Here, we assumed that all these processes led to an increase in the solubility of metal at the SiO2/metal. We systematically varied the value of the interfacial solubility, Ce over a wide range and showed that the solubility strongly affects the distribution of copper and the local electric field
within the dielectric. This changes the mechanism by which failure occurs from one where copper must penetrate all the way
through the dielectric to one where copper penetration is limited to a thin layer near the surface. The solubility levels
required to alter the failure mechanism, 1026–1027 atoms/m3, are within the realm of possibility and have been reported in the context of fabricating Cu-SiO2 resistive switching elements for memory applications. 相似文献

An understanding of the complex problems of land-use competition requires an appreciation of natural processes, cultural values, economic imperatives and political agendas. This integrated understanding is an important component of the study programme for higher education students seeking a professional qualification in landscape architecture. A repertoire of game templates is introduced as an initial step in formulating a conceptual framework for the curriculum/games designer to explore the potential of play in ecological landscape planning. The concepts of social action space, permissible action space and motivational action space are used to investigate the qualities of each template for further game design development. The abstraction of these concepts may assist the designer to move beyond the usability of games into viewing their value as a learning method. 相似文献
