We apply an online optimization process based on machine learning to the production of Bose-Einstein condensates. BEC is typically created with an exponential evaporation ramp that is optimal for ergodic dynamics with two-body s-wave interactions and no other loss rates, but likely sub-optimal for real experiments. Through repeated machine-controlled scientific experimentation and observations our ’learner’ discovers an optimal evaporation ramp for BEC production. In contrast to previous work, our learner uses a Gaussian process to develop a statistical model of the (...) relationship between the parameters it controls and the quality of the BEC produced. We demonstrate that the Gaussian process machine learner is able to discover a ramp that produces high quality BECs in 10 times fewer iterations than a previously used online optimization technique. Furthermore, we show the internal model developed can be used to determine which parameters are essential in BEC creation and which are unimportant, providing insight into the optimization process of the system.

Alain Badiou offers a distinctive interpretation of time, anchored in his unique metaphysics and philosophy of the event. For Badiou, time is interventional, demarcating a disjunction between two incommensurable sequences of rupture in human history. The concept of disjunction occupies a pivotal role in Badiou’s philosophy of both love and time. This paper provides a comprehensive examination of the temporality of love within the context of Badiou's philosophy. We argue that, when viewed through Badiou’s philosophical lens, love provides an invaluable (...) vantage point for understanding the very creation and transformation of time. As this chapter progresses, a concise exposition of Badiou's metaphysics and his theory of truth procedure is furnished, emphasizing facets that resonate with his philosophy of love. Time is explored from three vantage points: time between worlds, time within a world, and time as difference-as-such. These distinct conceptions of time, when examined in light of love, provide a fertile ground for further developing his concept of time. (shrink)

This paper addresses whether universal, general education programs are enough to satisfy basic criteria of human rights, or whether comprehensive family planning programs, in conjunction with universal education programs, might also be morally required. Even before the Reagan administration instituted the ‘global gag rule’ at the 1984 conference in Mexico City, prohibiting funding to nongovernmental organizations that included providing information about abortion as a possible method of family planning, the moral acceptability of family planning programs has been called into question. (...) This paper makes a moral argument for family planning by appealing to both data and to theory: data about the efficacy of universal and comprehensive family planning education programs at reducing fertility and infant mortality, and theory about what is required for the establishment of autonomy. It reasons that universal educational programs are insufficient for the promotion of autonomy, and therefore argues on substantive autonomy grounds for comprehensive family planning programs in addition to universal education programs.

La idea de que los delirios son creencias es apoyada por la observación de que los delirios, al igual que las creencias, son usados en el razonamiento. Sin embargo, los delirios tienen otras características que son difíciles de explicar por medio de una teoría doxástica —por ejemplo, los delirios persisten a pesar de la evidencia en su contra y algunas veces entran en conflicto con las acciones del agente (de maneras en que las creencias parecerían no hacerlo), dando lugar a (...) lo que se conoce como el fenómeno de la doble cuenta—. Estas características han motivado teorías no doxásticas, que argumentan que los delirios son otro tipo de fenómeno mental (e.g., imaginaciones o actos de habla vacíos). Mientras que las teorías no-doxásticas pueden explicar dichas características de los delirios—como su persistencia a pesar de la evidencia en su contra y el fenómeno de la doble cuenta— estas teorías tienen dificultades para explicar las características de los delirios que los hacen similares a las creencias. Nos encontramos entonces en un punto muerto en el que ni los enfoques doxásticos ni los no doxásticos pueden explicar todas las características de los delirios. En este artículo, propongo avanzar en este debate mostrando que la propuesta doxástica puede, después de todo, dar cuenta tanto de las características de los delirios que los hacen similares a las creencias como de sus demás características. Basándome en literatura reciente en epistemología, argumento que las creencias (racionales) puede estar motivadas por factores no evidenciales (e.g. pragmáticos o emocionales) y que estos factores sirven para explicar las características aparentemente desconcertantes de los delirios. También propongo que categorizar las creencias a través de dos compartimentos funcionales, el implícito y el explícito, nos ayuda a entender la interacción dinámica entre creencias delirantes y no delirantes.

Simultaneous discovery in science has been a subject of close historical investigations, not only for assessing claims of priority, which occasionally generate controversy rather than consensus, but also for understanding the cultural and intellectual context of the time. Thomas S. Kuhn is a pioneer in the contextual study of simultaneous discovery, and his paper on the formulation of the first law of thermodynamics has already become a classic.

Formal definitions of the following concepts of animal ecology are given: environment, niche, locality, local population, natural population, community, ecosystem. Five primitive (undefined) notions are used including "animal", "offspring" and "habitat", the latter in the sense of Charles Elton. The defining equations for the environment of one animal are first given, then niche (in the Elton sense) is formally defined in terms of the environment. The fifth primitve notion "habitat" is then introduced in order to define the remaining concepts.
