Thorncliffe Formation: A proglacial to subglacial lacustrine basin sequence, Greater Toronto Region, Canada

open access: yesBoreas, EarlyView.
Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Properties of enhançons in supergravity [PDF]

open access: yes, 2003
A certain class of naked singularities, related to N = 2 pure super Yang-Mills theory, are resolved in string theory with the enhançon mechanism. We study the properties of the enhançon in supergravity.

Einstein Supergravity and New Twistor String Theories

open access: yes, 2006
A family of new twistor string theories is constructed and shown to be free from world-sheet anomalies. The spectra in space-time are calculated and shown to give Einstein supergravities with second order field equations instead of the higher derivative ...

Inter‐disciplinary perspectives on sustainability in machinery manufacturing

open access: yesInternational Journal of Management Reviews, EarlyView.
Abstract Perspectives on economic, social and environmental sustainability in machinery manufacturing are changing. These are predominantly driven by increased consumer, firm and public knowledge on the importance of sustainability and the role that machinery manufacturers can play to achieve sustainability outcomes.

Aspects of hydrodynamics in AdS/CMT [PDF]

open access: yes, 2013
Condensed matter theory is the study of systems at finite density. In this thesis we will attempt to argue that gauge-gravity dualities can give deep and meaningful insights into the behaviour of strongly coupled condensed matter systems. The first three

Zebrafish as a practical and convenient model for the study of photodynamic and photothermal therapy of solid tumors: A scoping review

open access: yesPhotochemistry and Photobiology, EarlyView.
Zebrafish provide a high‐throughput, optically transparent platform for cancer and drug screening. Their ~80% genetic homology, xenograft compatibility, and transgenic strains enable targeted photosensitizer screening, real‐time ROS and tumor imaging, and mechanistic assays, while fish embryo acute toxicity (FET) and in vitro tests streamline toxicity ...

The bulk from the boundary; holography and AdS/CFT [PDF]

open access: yes, 2008
In this thesis we consider various methods by which one can extract (in detail) the metric structure of asymptotically anti-de Sitter spacetime, using only information from the boundary.

Strongly-coupled QFTs from string theory

open access: yes, 2022
Strongly-coupled regimes of quantum field theory (QFT) are notoriously challenging to explore. In this thesis, which is divided into two parts, I address the question from a string theoretic perspective.

Retaining Models of Human Evolution After Repeated Falsifications—Why?

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
Two 19th century paradigms of human evolution emerged: Humans are subdivided into isolated populations in an evolutionary tree, versus human populations interbreed (gene flow) with no isolates. The tree model has been rejected whenever tested since the 1970's, whereas gene flow consistently fits.

Anomalies for Galilean fields

open access: yes, 2018
We initiate a systematic study of `t Hooft anomalies in Galilean field theories, focusing on two questions therein. In the first, we consider the non-relativistic theories obtained from a discrete light-cone quantization (DLCQ) of a relativistic ...
