Time--delay autosynchronization of the spatio-temporal dynamics in resonant tunneling diodes

The double barrier resonant tunneling diode exhibits complex spatio-temporal patterns including low-dimensional chaos when operated in an active external circuit. We demonstrate how autosynchronization by time--delayed feedback control can be used to select and stabilize specific current density patterns in a noninvasive way. We compare the efficiency of different control schemes involving feedback in either local spatial or global degrees of freedom. The numerically obtained Floquet exponents are explained by analytical results from linear stability analysis.Comment: 10 pages, 16 figure

Living with persistent pain: experiences of older people receiving home care.

Background. Although the topic of pain among older people has received increasing interest, little is still known about how pain is experienced or handled by those who no longer manage independently but depend on professionals for help with daily living. Developing pain management for older people requires such knowledge. Aim. To explore sense of self, sense of pain, daily living with pain, sense of others and ways of handling pain in older people with persistent pain. Methods. Interviews with 90 older people receiving home care from nursing auxiliaries in their own homes or in sheltered accommodation were collected from January to June 2000. A typology of older people in persistent pain was developed. Activities for handling pain were examined using content analysis. Findings. Respondents' experiences of themselves and their pain varied. Two groups of older people, considered as 'competent and proud' and 'confident and serene', expressed satisfaction in spite of pain, while the groups 'misunderstood and disappointed' and 'resigned and sad' expressed dissatisfaction. The most common strategies used were medication, rest, mobility, distracting activities and talking about pain. Respondents chose strategies by balancing the advantages of the activities against the disadvantages these brought for their daily living. Conclusion. This study indicates that characteristics of the older people, such as their way of experiencing themselves, how pain affects their daily life and how they perceive effects and side-effects of pain management are areas that need to be identified when staff assess pain and plan pain management. Caring for older people in pain could be improved by listening to and believing their complaints, evaluating effects and side-effects from medications and nonpharmacological pain management and by emphasising the importance of common everyday activities such as mobility and distraction to relieve pain

Parametric Amplification of Propagating Spin Waves in Ferrite Films

Amplification of a weak signal spin wave by a strong pump spin wave propagating in yttrium iron garnet film was observed for the first time. A theoretical explanation of this effect is given on the basis of the four-wave parametric processes

The lived-experiences of family caregivers of mentally ill relatives

AIM: The aim of this paper is to report a study conducted to explore the meanings of the lived experiences that Chinese family caregivers in Malaysia ascribed to the care they provided to relatives with severe and persistent mental illness. BACKGROUND: In the past, many researchers have used quantitative approaches to explore the experiences of family caregivers of relatives with severe and persistent mental illness. However, the results of these studies have been far from conclusive because of serious methodological flaws. In addition, a large majority of these studies were conducted in western cultures, and it has been difficult to transfer the results to family caregivers in oriental cultures. METHOD: The philosophy of Martin Heidegger underpinned the study. Qualitative data were collected mainly through in-depth interviews with 19 criterion-selected Chinese family caregivers of relatives with severe and persistent mental illness in 2002. FINDINGS: We present the emergent themes reflecting the meaning structures of managing, enduring, and surviving the day-to-day experiences of the Chinese family caregivers. The impact of the stigma of the relatives' mental illness on family caregivers and families is pervasive and strong. As a result, family caregivers tried to avoid talking about their relative's mental illness with extended family or friends in order to protect their families from 'losing face'. In addition, most family caregivers believed that adopting positive behaviours and attitudes helped them cope with caregiving. CONCLUSION: Mental health nurses need to help Chinese family caregivers to cope with the stresses and stigmas of their relatives' mental illnesses through psychosocial education or family intervention, and to provide them with culturally-congruent care. They should also educate the public about mental health and ill health through health promotion and education
