Design, analysis and implementation of bulk-synchronous parallel algorithms, data structures and techniques by Siniolkis, C

“…The methods considered in this thesis - both theoretically and experimentally - embody deterministic and randomized techniques for the efficient realization of fundamental algorithms (broadcasting, computing parallel-prefixes, load-balancing, list-contracting, merging, sorting, integer-sorting, selecting, searching and hashing), data structures (heaps, search trees and hash tables) and applications (computational geometry, parallel model simulations and structured query language primitives).…”

Synthesis and conformational analysis of fluorinated pyrrolidines by Combettes, L, Lorraine Combettes

“…Finally, we investigated the level of diastereocontrol displayed by these cyclisations as a function of the E/Z geometry of the starting aminated allylsilane. </p> <p><em>Conformational analysis</em></p> <p>Moreover the 3-fluoropyrrolidines obtained via iodoamination served to investigate the stereoelectronic influence of the fluorine gauche effect on ring conformations. …”

Enceladus plume structure and time variability: comparison of Cassini observations by Teolis, BD, Perry, ME, Hansen, CJ, Waite, JH, Porco, CC, Spencer, JR, Howett, CJA

“…This complex spatial variability and dynamics may result from time-variable tidal stress fields interacting with subsurface fissure geometry and tortuosity beyond detectability, including changing gas pathways to the surface, and fluid flow and boiling in response evolving lithostatic stress conditions. …”

Conjectures on counting associative 3-folds in $G_2$-manifolds by Joyce, D

“…Several areas of Symplectic Geometry – Gromov–Witten theory, Quantum Cohomology, Lagrangian Floer cohomology, Fukaya categories – are built using ‘counts’ of moduli spaces of J-holomorphic curves in Y , but give an answer depending only on the symplectic manifold (Y,ω), not on the (almost) complex structure J. …”

Single channel Kondo physics in triple quantum dots by Jarrold, TF

“…<p>In this thesis we investigate a system of three tunnel-coupled quantum dots, arranged in a triangular geometry and attached to a single metallic conduction band, using both analytic and semi-analytic methods and the numerical renormalisation group technique. …”

Black hole jets, accretion discs and dark energy by Potter, WJ

“…I develop an inhomogeneous jet model with a magnetically dominated parabolic accelerating base, transitioning to a slowly decelerating conical jet, with a geometry set by radio observations of M87.</p> <p>This model is able to reproduce the simultaneous multiwavelength spectra of all 38 Fermi blazars with redshifts in unprecendented detail across all wavelengths. …”

Three-dimensional device structures for photovoltaic applications by Urban, H, H. Urban

“…Their power-conversion efficiencies, below 13% and 9% respectively, still limit the economic viability of these technologies. The geometry and optical properties of photonic crystals can be used to improve the absorption and charge collection efficiencies of these devices. …”

A microfluidic platform reveals differential response of regulatory T cells to micropatterned costimulation arrays. by Lee, J, Dustin, M, Kam, L

Residual stress analysis in shot peened and fretting fatigued samples by the eigenstrain method by Korsunsky, A, Kim, K, Golshan, M, Regino, G

“…Fretting fatigue loading was carried out in hte pad-on-flat geometry using the Oxford in-line fretting rig. Flat-and-rounded pad shape was used to introduce the contact tractions and internal stress fields typical of the target application in aeroengine design. …”

Bordism categories and orientations of gauge theory moduli spaces by Joyce, D, Upmeier, M

“…<p>This is the second paper of a series that develops a bordism-theoretic point of view on orientations in enumerative geometry. The first paper is arXiv:2312.06818. This paper focuses on those applications to gauge theory that can be established purely using formal arguments and calculations from algebraic topology.…”

Gravity anomalies, flexure and crustal structure at the Mozambique rifted margin by Watts, A

“…The different amounts of sediment and underplate at rifted margins help, in fact, to explain the diversity of the edge effect, although they obscure the mechanics, styles and geometry of rifting. In this paper, combined 2-dimensional flexural backstripping and gravity modelling techniques are used to quantify the contribution of rifting, sediment loading and magmatic underplating to the edge effect anomaly at the Mozambique margin. …”

Governance in international trade beyond the state: Collective agency, the actorness of trading blocs, and institutional learning by Stiller, KT

“…It entails an increasingly variable and overlapping geometry of cooperation. The theory is then applied to explain the governance of international trade, where trading blocs emerge as transnational actors. …”

Enhanced intersystem crossing and transient electron spin polarization in a photoexcited pentacene–trityl radical by Avalos, CE, Richert, S, Socie, E, Karthikeyan, G, Casano, G, Stevanato, G, Kubicki, DJ, Moser, JE, Timmel, CR, Lelli, M, Rossini, AJ, Ouari, O, Emsley, L

Here, we present transient electron paramagnetic resonance (EPR) measurements on three pentacene derivatives tethered to Finland trityl, BDPA, or TEMPO radicals to explore the influence of the nature of the radical on the spin polarization transfer. …”
