Spherical deconstruction [PDF]

open access: yesPhysics Letters B, 2005
We present evidence that N=1* SUSY Yang-Mills provides a deconstruction of a six-dimensional gauge theory compactified on a two-sphere. The six-dimensional theory is a twisted compactification of N=(1,1) SUSY Yang-Mills theory of the type considered by Maldacena and Nunez (MN).

On the sphericity test with large-dimensional observations [PDF]

open access: yes, 2013
In this paper, we propose corrections to the likelihood ratio test and John's test for sphericity in large-dimensions. New formulas for the limiting parameters in the CLT for linear spectral statistics of sample covariance matrices with general fourth ...

Preparation of 304 Stainless Steel Powder for 3D Printing by Vacuum-Induced Multistage Atomization

open access: yesFrontiers in Materials, 2021
A vacuum-induced multistage atomization process was adopted to fabricate the high-performance 304 stainless steel powder for 3D printing, based on the flexible control of the droplet spheroidization and solidification process. The 36.7 μm-median diameter

Are Nanoparticles Spherical or Quasi‐Spherical? [PDF]

open access: yesChemistry – A European Journal, 2015
AbstractThe geometry of quasi‐spherical nanoparticles is investigated. The combination of SEM imaging and electrochemical nano‐impact experiments is demonstrated to allow sizing and characterization of the geometry of single silver nanoparticles.

The global geometrical property of jet events in high-energy nuclear collisions

open access: yes, 2020
We present the first theoretical study of medium modifications of the global geometrical pattern, i.e., transverse sphericity ($S_{\perp}$) distribution of jet events with parton energy loss in relativistic heavy-ion collisions.

Spherical Categories

open access: yesAdvances in Mathematics, 1999
This paper is a study of monoidal categories with duals where the tensor product need not be commutative. The motivating examples are categories of representations of Hopf algebras and the motivating application is the definition of 6j-symbols as used in topological field theories. We introduce the new notion of a spherical category.
