No full textTranscript (64 pages) of an interview by Becky B. Lloyd with Byron J. Sharp, on September 14, 2004. From tape number 712 in the "Saving the Legacy" Oral History ProjectMr. Sharp was born October 13, 1921, in Salt Lake City, Utah. He enlisted in the Army in May 1942, and took basic training at Camp Roberts, California, where he became an instructor. He was recruited for glider pilot training in Colorado and received gunnery training in Kentucky. After transfer to Spanhoe, England, in the fall of 1943, he was assigned to the 315th Troop Carrier Group, 52nd Troop Carrier Wing, IX Troop Carrier Command in the 9th Air Force. He describes his experiences landing paratroopers in gliders during the D-Day invasion. He was involved in Market Garden and returned to the states when the war ended. As a civilian, Sharp received his PhD in Geology, worked for the USGS, and retired from the Department of Energy. Interviewed by Becky Lloyd. 64 pages
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)

Physiological sharp wave-ripples and interictal events in vitro: What’s the difference?
No full textSharp wave-ripples and interictal events are physiological and pathological forms of transient high activity
in the hippocampus with similar features. Sharp wave-ripples have been shown to be essential in memory
consolidation, while epileptiform (interictal) events are thought to be damaging. It is essential to grasp the
difference between physiological sharp wave-ripples and pathological interictal events in order to
understand the failure of control mechanisms in the latter case. We investigated the dynamics of activity
generated intrinsically in the CA3 region of the mouse hippocampus in vitro, using four different types of
intervention to induce epiletiform activity. As a result, sharp wave-ripples spontaneously occurring in CA3
disappeared, and following an asynchronous transitory phase, activity reorganized into a new form of
pathological synchrony. During epileptiform events, all neurons increased their firing rate compared to sharp
wave-ripples. Different cell types showed complementary firing: parvalbumin-positive basket cells and
some axo-axonic cells stopped firing due to a depolarization block at the climax of the events in high
potassium, 4-aminopyridine and zero magnesium models, but not in the gabazine model. In contrast,
pyramidal cells started firing maximally at this stage. To understand the underlying mechanism we
measured changes of intrinsic neuronal and transmission parameters in the high potassium model. We found
that the cellular excitability increased and excitatory transmission was enhanced, whereas inhibitory
transmission was compromised. We observed a strong short-term depression in parvalbumin-positive basket
cell to pyramidal cell transmission. Thus, the collapse of pyramidal cell perisomatic inhibition appears to be
a crucial factor in the emergence of epileptiform events
