I find that data for the reaction 10Be(p, γ) can be reasonably well described with a 1/2+ resonance whose width is 640 keV, rather than the accepted 210 keV. Disciplines Physical Sciences and Mathematics | Physics Comments Suggested Citation: Fortune, H.T. (2006). Energy and Width of 11B(1/2+, T = 3/2).

Generally, a superconducting nanowire single-photon detector (SNSPD) is composed of wires with typical width ? 100 nm . Recent studies have found that strips micrometer-scale can also detec...
The synthesis and characterization of two direct platinum (1 and 6a/b) and three ethynyl-platinum corannulene derivatives (2, 8 and 9), bearing 2, 4, or 5 square planar platinum centers, are presented. The structure of the bowl bearing substituents remains comparable to corannulene and the dynamic behavior of the bowl inversion as assessed by VT NMR supports a persistent bowl structure in solut...
Bowl-in-bowl stacking of buckybowls on a copper surface is observed via scanning tunneling microscopy (STM) at low temperatures and characterized by density functional theory (DFT) calculations.
Human studies suggest that prior emotional responses are stored within the brain as associations called somatic markers and are recalled to inform rapid decision-making. Consequently, behavioural and physiological indicators of arousal are detectable in humans when making decisions, and influence decision outcomes. Here we provide the first evidence of anticipatory arousal around the time of de...
To understand the pathogenesis of chronic inflammatory disease, we analyzed an experimental mouse model of chronic lung disease with pathology that resembles asthma and chronic obstructive pulmonary disease (COPD) in humans. In this model, chronic lung disease develops after an infection with a common type of respiratory virus is cleared to only trace levels of noninfectious virus. Chronic infl...
The molecular chaperone Hsp90 (heat shock protein 90) maintains the conformation, stability, and activity of several key oncogenic proteins, such as EGF receptor (EGFR), cyclin-dependent kinases, Raf, and p53, which are collectively known as Hsp90 client proteins (Whitesell and Lindquist, 2005). The chaperone function of Hsp90 requires the formation of a multichaperone complex, which is depende...
The cerebral cortex must have access to an eye position signal, as humans can report passive changes in eye position in total darkness, and visual responses in many cortical areas are modulated by eye position. The source of this signal is unknown. Here we demonstrate a representation of eye position in monkey primary somatosensory cortex, in the representation of the trigeminal nerve, near cel...
We propose and demonstrate a method to gauge and optimize the signal-to-noise ratios (SNRs) in lensless imaging using partially coherent sources. Through spatial filtering we tuned the coherence width of an incoherent soft x-ray undulator source, and we deduce that there exists an optimal spatial filter setting for imaging micrometer-sized objects, while high-resolution imaging is best executed...
