The Schwinger point

open access: yesJournal of High Energy Physics, 2019
The Sommerfield model with a massive vector field coupled to a massless fermion in 1+1 dimensions is an exactly solvable analog of a Bank-Zaks model.

FastNano Liquid: An Automated Platform for Small‐Angle X‐ray Scattering‐Based Materials Discovery

open access: yesAdvanced Engineering Materials, EarlyView.
We present FastNano Liquid, an automated small‐ and wide‐angle X‐ray scattering platform for the combined synthesis and characterization of (nano)materials. The platform is coupled to varied reactor workflows for both in situ studies of reaction kinetics and ex situ screening of synthesis conditions to support machine learning‐guided exploration ...

Effect of Cu and CuP Additions on the Microstructure and Nanoindentation‐Based Fracture Behavior of CoNiAlSi Ferromagnetic Shape Memory Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
Cu and combined Cu–P microalloying refine the microstructure and enhance the nanoindentation‐derived fracture resistance of CoNiAlSi ferromagnetic shape memory alloys without suppressing the martensitic transformation. Comparative SEM, DSC, and nanoindentation results reveal that the CuP‐containing alloy provides the most balanced response, achieving ...

Laws of Science and Laws of Nature in an Evolutionary Knowledge Ecology

open access: yes, 2019
This chapter presents an evolutionary ecological approach in which human knowledge is studied as the ecology of interacting datainformation-knowledge systems developing in time as a consequence of incessant learning from interactions with the environment

An algebraic approach to the analytic bootstrap

open access: yesJournal of High Energy Physics, 2017
We develop an algebraic approach to the analytic bootstrap in CFTs. By acting with the Casimir operator on the crossing equation we map the problem of doing large spin sums to any desired order to the problem of solving a set of recursion relations.

Mandatory reporting laws: Their origin, nature, and development over time

open access: yes, 2015
Dozens of countries have enacted mandatory reporting laws in various forms to respond to child abuse and neglect. Other countries including England are currently considering whether to introduce them, and if so in what form.

Rotary 3D Printing With Integrated Electroplating

open access: yesAdvanced Engineering Materials, EarlyView.
A rotary material extrusion platform integrates localized copper electroplating with printing and encapsulation to fabricate cylindrical polymer–metal structures containing fully embedded, low‐resistance conductive pathways that enable internal Joule heating and thermally activated shape‐memory responses.

Quasinormal corrections to near-extremal black hole thermodynamics

open access: yesJournal of High Energy Physics
Recent work on the quantum mechanics of near-extremal non-supersymmetric black holes has identified a characteristic T 3/2 scaling of the low temperature black hole partition function. This result has only been derived using the path integral in the near-
