    Korshunov instantons out of equilibrium

    Get PDF
    Zero-dimensional dissipative action possesses non-trivial minima known as Korshunov instantons. They have been known so far only for imaginary time representation that is limited to equilibrium systems. In this work we reconstruct and generalise Korshunov instantons using real-time Keldysh approach. This allows us to formulate the dissipative action theory for generic non-equilibrium conditions. Possible applications of the theory to transport in strongly biased quantum dots are discussed..Comment: 6 pages, 2 figure

    Younger adults in long-term care facilities : a review of the literature concerning their characteristics and environmental design, staffing and programming needs

    Get PDF
    Concern over provision of long-term care for an increasing seniors\u27 population has tended to obscure the fact that younger persons may also require this level of care. This report focuses on the non-geriatric population in long-term care: specifically, on adults between the aged of 20-64. Within this group, the emphasis is on those requiring facility care. While there is general consensus (Ontario Medical Association Committee on Rehabilitation, 1980a and b; Reinecke, 1979; Nichols, 1978) that everything possible should be done to enable younger adult disabled persons to live out their lives in the community, it is recognized that for some individuals with severe congenital or accident-caused disabilities, community living is impossible. Others require periodic admission to an institution in order to continue to live most of the time in the community. Still others enter an institution at the late stages of a progressive deteriorating illness which they and/or their family caregivers can no longer manage in a community setting. For all of these groups, the objective must be to construct institutions that will best meet their physical and psycho-social needs -- that is, that provide the best possible physical care in the least restrictive, most emotionally and intellectually satisfying environment possible.Table of Contents: I INTRODUCTION.

    Transient deprotonation of bacterial halorhodopsin by photoexcited base

    Get PDF
    AbstractThe excited singlet state of 6-methoxyquinoline is basic enough to abstract a proton from water and generate OH−. Pulse excitation of such a solution undergoes a massive transient alkalinization. This procedure was employed to monitor the deprotonation of the Schiff base of halorhodopsin. Both the deprotonation and reprotonation of the chromophore are diffusion controlled reactions

    Towards more elder friendly hospitals : final report - studies 3b and 3c

    Get PDF
    Deconditioning and loss of functional status occurs at high rates among elderly persons admitted to hospitals, independent of their medical condition. Design of the physical environment is one of several explanations as to why this may occur. The two pilot studies described in this report tested selected environmental modifications designed to overcome some of the physical barriers to safe independent transfer, mobility, and toileting identified in Studies 1 and 2 of the Towards More Elder Friendly Acute Hospitals Research Project. One pilot study (Study 3b) took place in two originally identical bedrooms at Burnaby Hospital, a community hospital located in Burnaby, British Columbia. The second (Study 3c) took place in two adjacent bathrooms. In both Studies 3b and 3c, one room remained "as is " and the other was modified; 36 community-dwelling volunteers aged 75+ performed a series of tasks in both the original and the modified bedrooms and the two toilet areas. Order of exposure to the "typical" and modified rooms was counterbalanced. Three types of data were collected: subjective, physiological and video. The environment modifications of interest were rated by participants for ease of use, for helpfulness, and/or for appeal and they were asked to respond to questions such as "what did you like most/least about the rooms and why"? Heart rate was measured as participants rested in each bedroom and postural sway was recorded as they transferred from the bedroom to the bathroom and while they pretended to use the toilet and "freshen up" at the sink. To document gross movement, gestures, coping actions and facial expressions, high resolution webcams were mounted in the bedrooms and bathrooms and a camcorder followed the participants throughout the study. A number of lessons were learned from the study about relatively inexpensive design features that if implemented in new construction and retrofitting, have the potential to increase the elder friendliness of FH hospitals (e.g. movement activated lighting at the entrance to the bathroom). A number of useful lessons were also learned concerning equipment and procedures for remote monitoring of physiological functioning and stress. The report ends with a series of recommendations that include recognizing the diversity of the frail elder population of British Columbia and designing physical space in hospitals to meet the needs of patients with multiple chronic physical and/or cognitive impairments.

    Rethinking retirement

    Get PDF
    Four of the seven chapters in this volume are based on papers originally presented at the 6th Annual John K. Friesen Lecture Series in Gerontology held at Simon Fraser University April 3-4, 1995. The impetus for the symposium and the volume was provided by the profound changes that are taking place in Canada and throughout the developed world in the way retirement is being conceptualized, timed, and reflected in corporate and public policy.\u27 A systematic examination of these changes seemed warranted.TABLE OF CONTENTS: 1.

    Note on Branching

    It has been demonstrated that the spectrum of the molecular graph contains information about the extent of branching of the molecular skeleton. In particular, the largest eigenvalue, xi, in the spectrum has been shown to be closely related to the total number of walks in the graph (eqs. (11) and (15)). Thus, a justification of the recent empirical finding that x1 is a measure of branching9,in has been obtained

    Effects of Cattle Grazing on a Perennial Legume, Bitumen Trefoil (\u3ci\u3eBituminaria bituminosa\u3c/i\u3e (L.) Stirton), in a Mediterranean Grassland

    A six-year study was conducted in a Mediterranean grassland in north-eastern Israel to investigate the effects of cattle grazing management on a perennial legume, Bitumen Trefoil (Bituminaria bituminosa (L.) Stirton). The relationship between grazing pressure and its relative plant cover was studied in the context of inter-annual variation in rainfall. Treatments included manipulations of stocking rates (moderate, heavy and very heavy) and of grazing regimes (continuous vs. seasonal), in a factorial design. The results showed that inter-seasonal rainfall variation was a dominant factor in the expression of plant cover changes of this species. Grazing showed no significant effect on plant cover of this species even under very heavy grazing pressure. The importance of this species as complementary forage at the end of the grazing season and its resistance to grazing is discussed within the framework of persistence of dominant species, despite wide variation in grazing regimes and climatic condition
