Robust delay-dependent H∞ control of uncertain time-delay systems with mixed neutral, discrete, and distributed time-delays and Markovian switching p…
2011
Author's version of an article published in the journal: IEEE Transactions on Circuits and Systems I: Regular Papers. Also available from the publisher at: http://dx.doi.org/10.1109/tcsi.2011.2106090 The problem of robust mode-dependent delayed state feedback H ∞ control is investigated for a class of uncertain time-delay systems with Markovian switching parameters and mixed discrete, neutral, and distributed delays. Based on the LyapunovKrasovskii functional theory, new required sufficient conditions are established in terms of delay-dependent linear matrix inequalities for the stochastic stability and stabilization of the considered system using some free matrices. The desired control is …
Aging and longevity: An evolutionary approach
2021
Abstract In the chapter, first of all, the definition of aging, longevity, and the various types of aging are discussed. Then, analyzing various theories of aging, it is recalled how evolution teaches us that there should be no genes selected to promote aging. Aging is not planned but derives from the accumulation of physical damage, due to limited investments in maintenance and repair as well as from the epigenetic changes. After sufficient time has passed, the increasing levels of these defects interfere with the performance of tissues and organs, resulting in a breakdown of self-organizing system and a reduced ability to adapt to the environment.
Determination of Death in Execution by Lethal Injection in China.
2018
Abstract:Since 1997, execution in China has been increasingly performed by lethal injection. The current criteria for determination of death for execution by lethal injection (cessation of heartbeat, cessation of respiration, and dilated pupils) neither conform to current medical science nor to any standard of medical ethics. In practice, death is pronounced in China within tens of seconds after starting the lethal injection. At this stage, however, neither the common criteria for cardiopulmonary death (irreversible cessation of heartbeat and breathing) nor that of brain death (irreversible cessation of brain functions) have been met. To declare a still-living person dead is incompatible wi…
Self-reported reasons for on-duty sleepiness among commercial airline pilots
2021
Experimental and epidemiological research has shown that human sleepiness is determined especially by the circadian and homeostatic processes. The present field study examined which work-related factors airline pilots perceive as causing on-duty sleepiness during short-haul and long-haul flights. In addition, the association between the perceived reasons for sleepiness and actual sleepiness levels was examined, as well as the association between reporting inadequate sleep causing sleepiness and actual sleep-wake history. The study sample consisted of 29 long-haul (LH) pilots, 28 short-haul (SH) pilots, and 29 mixed fleet pilots (flying both SH and LH flights), each of whom participated in a…
Unmet care needs are common among community-dwelling older people with memory problems in Finland
2021
Aims: Ageing in place has become a policy priority. Consequently, residential care has been reduced, and more older people with multiple care needs reside at home with the help of informal care and home care services. An increasing share of these people has memory disorders. We examined the extent to which memory problems, in addition to other individual characteristics, are associated with unmet care needs among community-dwelling older people. Methods: The study employed cross-sectional survey data from community-dwelling people aged 75+ collected in 2010 and 2015, analysed using binary logistic regression analysis. The study population consisted of people who had long-term illnesses or d…
Il diritto alla retribuzione proporzionata e sufficiente: problemi e prospettive
2010
L''articolo esamina il modo in cui l''art. 36 della Costituzione ha trovato concreta applicazione nell''esperienza giurisprudenziale. L''accurato esame delle teorie proposte in dottrina e della giurisprudenza conduce a ricostrire in termini attuali la questione della retribuzione proporzionata e sufficiente, criticando le numerose oscillazioni dei giudici sul tema.
Physiological and autonomic stress responses after prolonged sleep restriction and subsequent recovery sleep in healthy young men
2018
Purpose Sleep restriction is increasingly common and associated with the development of health problems. We investigated how the neuroendocrine stress systems respond to prolonged sleep restriction and subsequent recovery sleep in healthy young men. Methods After two baseline (BL) nights of 8 h time in bed (TIB), TIB was restricted to 4 h per night for five nights (sleep restriction, SR, n = 15), followed by three recovery nights (REC) of 8 h TIB, representing a busy workweek and a recovery weekend. The control group (n = 8) had 8 h TIB throughout the experiment. A variety of autonomic cardiovascular parameters, together with salivary neuropeptide Y (NPY) and cortisol levels, were assessed.…
