The inclusive B→Xcℓν branching fraction, B cℓν, the Cabibo-Kobayashi-Maskawa matrix element, and other heavy quark parameters were determined from a simultaneous fit moments of the hadronic mass and lepton-energy distributions in semileptonic B-meson decays. Using data recorded with BABAR detector, the values were mesured as function of the lower limit on the lepton energy. The vaues for Bceν were extracted using heavy quark expansions to the order of 1÷m b3. The stated errors were referred to the experimental, HQE and additional (...) theoretical uncertainties.

Merker's insightful broad review fertilely recasts the mind/brain issue, but the phenomenological appeals require additional considerations of behavioral and neural flexibility. Motor equivalences and perceptual constancies may be cortical contributions to a “robotic” tectal orientation mechanism. Intermediate “third layers” of associative neural networks, each with a few diffusely summing convergence-divergence modules, may be the economical expedient by which evolution has extended the limited unity-in-diversity of sensorimotor coordination to perception, action, thinking, and memory.

Many philosophers as well as many biological psychologists think that recent experiments in neuropsychology have definitively discredited any notion of freedom of the will. I argue that the arguments mounted against the concept of freedom of the will in the name of natural causal determinism are valuable but not new, and that they leave intact a concept of freedom of the will that is compatible with causal determinism. After explaining this concept, I argue that it is interestingly related to our (...) use of the first person pronoun “I.” I discuss three examples of our use of “I” in thought and language and submit a few questions I would like neuropsychologists to answer concerning the brain processes that might underlie those uses. I suggest answering these questions would support the compatibilist notion of freedom of the will I have offered in part 1 of the paper. (shrink)
This paper discusses sovereignty and examines in detail Hobbes's debates with the two leading legal theorists of his day, Coke and Hale, both Lord Chief Justices of the King's Bench. I argue that Hobbes came to change his mind somewhat about the desirability of divided sovereignty by the time, near the end of his life, that he wrote the Dialogue . But I also argue that Hobbes should have developed more than a very thin conception of the rule of law. (...) Hobbes should have been more open to the ideas that the jurists of his day were developing, especially the idea that the judiciary should have independent status. (shrink)
Brain–computer interfacing (BCI) aims at directly capturing brain activity in order to enable a user to drive an application such as a wheelchair without using peripheral neural or motor systems. Low signal to noise ratio’s, low processing speed, and huge intra- and inter-subject variability currently call for the addition of intelligence to the applications, in order to compensate for errors in the production and/or the decoding of brain signals. However, the combination of minds and machines through BCI’s (...) and intelligent devices (IDs) can affect a user’s sense of agency. Particularly confusing cases can arise when the behavioral control switches implicitly from user to ID. I will suggest that in such situations users may be insecure about the extent to which the resulting behavior, whether successful or unsuccessful, is genuinely their own. Hence, while performing an action, a user of a BCI–ID may be uncertain about being the agent of the act. Several cases will be examined and some implications for (legal) responsibility (e.g. establishing the presence of a ‘guilty mind’) are discussed. (shrink)
David Balme's major critical edition of Aristotle's largest and perhaps least studied treatise is based on a collation of the 26 known extant manuscripts and a study of the early Latin translations. Begun in 1975, with his work towards the Loeb editio minor of books VII–X, this edition of all ten books, including a very full apparatus criticus, was largely complete by 1989 when Professor Balme died, but it needed extensive work to put it in publishable form. This work has (...) been carried out by Allan Gotthelf, Balme's friend and associate. Volume I of the edition contains the complete text of the Historia Animalium, the critical apparatus, and Balme's introduction to the manuscripts, expanded and updated with the assistance of Friederike Berger, and in consultation with the editors of forthcoming editions of the extant medieval translations. A substantial index to the text has been provided by Liliane Bodson in collaboration with Professor Gotthelf. (shrink)
