Life extension

Life extension is the concept of extending the human lifespan, either modestly through improvements in medicine or dramatically by increasing the maximum lifespan beyond its generally-settled limit of 125 years. Several researchers in the area, along with "life extensionists", "immortalists" or "longevists" (those who wish to achieve longer lives themselves), postulate that future breakthroughs in tissue rejuvenation, stem cells, regenerative medicine, molecular repair, gene therapy, pharmaceuticals, and organ replacement (such as with artificial organs or xenotransplantations) will eventually enable humans to have indefinite lifespans (agerasia) through complete rejuvenation to a healthy youthful condition. The ethical ramifications, if life extension becomes a possibility, are debated by bioethicists. The sale of purported anti-aging products such as supplements and hormone replacement is a lucrative global industry. For example, the industry that promotes the use of hormones as a t

Collaborative coverage using a swarm of networked miniature robots

Nicolaus Correll, Alcherio Martinoli, Samuel Rutishauser

We study distributed coverage of environments with unknown extension using a team of networked miniature robots analytically and experimentally. Algorithms are analyzed by incrementally raising the abstraction level starting from physical robots, to realistic and discrete event system (DES) simulation. The realistic simulation is calibrated using sensor and actuator noise characteristics of the real platform and serves for calibration of the DES microscopic model. The proposed algorithm is robust to positional noise and communication loss, and its performance gracefully degrades for communication and localization failures to a lower bound, which is given by the performance of a non-coordinated, randomized solution. Results are validated by real robot experiments with miniature robots of a size smaller than 2 cm×2 cm×3 cm in a boundary coverage case study. Trade-offs between the abilities of the individual platform, required communication, and algorithmic performance are discussed.

Flexibilisierung der Wasserkraft in der Schweiz für zukünftige Aufgaben im internationalen Strommarkt

Felix Oberrauch, Anton Schleiss

La situation économique tendue en Europe ainsi que la surabondance des énergies solaire et éolienne, fortement subventionnées, dans le marché de l’électricité européen ont créé une situation de concurrence très défavorable pour la force hydraulique en Suisse. A court terme, les perspectives sont tellement sombres que beaucoup de sociétés n’osent plus investir dans l’extension de l’hydraulique bien que ceci soit indispensable à moyen terme pour atteindre les objectifs de la politique énergétique. Dans le passé, de telles perceptives ont toujours existées pour le domaine de l’hydraulique et celles-ci revenaient avec une périodicité de 5 à 8 ans. La bonne nouvelle est que ces perceptives ne se sont jamais concrétisées. La force hydraulique les a toutes surmontées avec succès et ceci est certainement dû à son caractère incontestablement durable. Pour que l’extension de la force hydraulique soit un succès dans cet avenir incertain, elle doit viser, en premier lieu, la flexibilisation de la production et des aménagements. La contribution suivante présente les possibilités constructives ainsi que les approches méthodiques lors de la planification de projets qui permettent de maîtriser avec succès les incertitudes de l’avenir.

Senescence (sɪˈnɛsəns) or biological aging is the gradual deterioration of functional characteristics in living organisms. The word senescence can refer to either cellular senescence or to senescence

Maximum life span

Maximum life span (or, for humans, maximum reported age at death) is a measure of the maximum amount of time one or more members of a population have been observed to survive between birth and death.
