Classification of Symmetry-Protected Phases for Interacting Fermions in Two Dimensions

open access: yes, 2018
Recently, it has been shown that two-dimensional bosonic symmetry-protected topological(SPT) phases with on-site unitary symmetry $G$ can be completely classified by the group cohomology class $H^3(G, \mathrm{U}(1))$.

EVALUATION OF THE UTILITY OF THE ANTERIOR CRUCIATE LIGAMENT RETURN TO SPORT AFTER INJURY (ACL-RSI) SCALE WITHIN PEDIATRIC ATHLETES

open access: yesOrthopaedic Journal of Sports Medicine, 2019
Background: The incidence of anterior cruciate ligament (ACL) injury and surgical reconstruction in youth athletes is increasing. In the United States, most athletes elect to undergo ACL reconstruction (ACLR), with the goal of returning to their previous

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Expedient Discovery of a Metallaphotoredox Cyanomethylation for Synthesizing α‐Aryl Nitriles

open access: yesChemistry – A European Journal, EarlyView.
A metallaphotoredox cyanomethylation reaction has been developed for the synthesis of valuable α‐aryl nitrile intermediates. The methodology was successfully applied to diverse medicinally‐relevant substrates, providing an expedient route to anti‐cancer Senexin compounds, while also removing the need for toxic cyanide reagents. The mechanism was probed
