Inclusive Hadronic Results at BaBar: ISR and Pentaquark Searches
We present recent measurements of hadronic cross-sections from the BaBar
experiment and report preliminary results on searches for pentaquark states.Comment: 4 pages, 9 postscript figues, contributed to the Proceedings of

Simplified likelihoods using linearized systematic uncertainties
This paper presents a simplified likelihood framework designed to facilitate
the reuse, reinterpretation and combination of LHC experimental results. The
framework is based on the same underlying structure as the widely used
HistFactory format, but with systematic uncertainties considered at linear
order only. This simplification leads to large gains in computing performance
for likelihood evaluation and maximization, compared to the original
experimental likelihoods. The framework accurately describes non-Gaussian
effects from low event counts, as well as correlated uncertainties in
combinations. While primarily targeted towards binned descriptions of the data,
it is also applicable to unbinned models.Comment: 19 pages, 8 figure
An investigation into the impact of coaching strategies with respect to physical and performance characteristics of male youth of varying biological maturation
This thesis will be presented as two standalone experimental chapters which will culminate in a thesis discussion linking the two papers under the overarching concept of maturation in male youth. Chapter 2 is currently under review in ‘Cogent Medicine’, and the intention of Chapter 2 is to identify physical, injury and performance-based differences between maturational groups within a general school-based population of 8 youth. These observed differences within Chapter 2 will then inform the methodology and coaching strategies utilised within Chapter 3, which will investigate the effectiveness of various coaching methods in order to maximise adaptation, motor ability and injury prevention within each maturational group. The outcome of this thesis hopes to inform practitioners as to how they can best implement their training programmes to maximise learning and adaptation across a range of biological maturation levels. Rather than just knowing when training should occur which has been investigated previously, it is hoped this thesis will provide insight into how coaching should occur to maximise learning within this diverse adolescent population. Due to the layout of this thesis with the individual papers, there is an element of content repetition throughout Chapters 1,2,3 and 4 which needs to be acknowledged, although the various contexts provides uniqueness throughout
Subjective preferences of varying menthol mouthwash concentrations
Menthol is a widely used, naturally occurring monoterpene alcohol that elicits a feeling of coolness and freshness upon application to the oral cavity, or skin (Stevens & Best, 2016).
Recently menthol has demonstrated improvements in time to exhaustion (Mündel & Jones, 2010) and time trial performance (Stevens et al., 2015), but no investigations have been
conducted to ascertain the preferred concentration of menthol mouth swill(s)
Menthol mouth rinsing evokes mixed responses in trained runners
Menthol is used to evoke pleasant feelings of coolness and freshness. Sport science has focused upon the topical or oral application of menthol to athletes, either directly on the skin or menthol soaked garments, and as a mouth rinse or in beverages
Fixed Parameter Undecidability for Wang Tilesets
Deciding if a given set of Wang tiles admits a tiling of the plane is
decidable if the number of Wang tiles (or the number of colors) is bounded, for
a trivial reason, as there are only finitely many such tilesets. We prove
however that the tiling problem remains undecidable if the difference between
the number of tiles and the number of colors is bounded by 43.
One of the main new tool is the concept of Wang bars, which are equivalently
inflated Wang tiles or thin polyominoes.Comment: In Proceedings AUTOMATA&JAC 2012, arXiv:1208.249
Scanning photocurrent microscopy reveals electron-hole asymmetry in ionic liquid-gated WS2 transistors
We perform scanning photocurrent microscopy on WS2 ionic liquid-gated field
effect transistors exhibiting high-quality ambipolar transport. By properly
biasing the gate electrode we can invert the sign of the photocurrent showing
that the minority photocarriers are either electrons or holes. Both in the
electron- and the hole-doping regimes the photocurrent decays exponentially as
a function of the distance between the illumination spot and the nearest
contact, in agreement with a two-terminal Schottky-barrier device model. This
allows us to compare the value and the doping dependence of the diffusion
length of the minority electrons and holes on a same sample. Interestingly, the
diffusion length of the minority carriers is several times larger in the hole
accumulation regime than in the electron accumulation regime, pointing out an
electron-hole asymmetry in WS2
