Raman Scattering Errors in Stimulated-Raman-Induced Logic Gates in ^{133}Ba^{+}.

^{133}Ba^{+} is illuminated by a laser that is far detuned from optical transitions, and the resulting spontaneous Raman scattering rate is measured. The observed scattering rate is lower than previous theoretical estimates. The majority of the discrepancy is explained by a more accurate treatment of the scattered photon density of states.

Biallelic Loss and Homologous Recombination Deficiency in Nonbreast/Ovarian Tumors in Germline Carriers.

Purpose: Breast and ovarian tumors in germline carriers undergo allele-specific loss of heterozygosity, resulting in homologous recombination deficiency (HRD) and sensitivity to poly-ADP-ribose polymerase (PARP) inhibitors. This study investigated whether biallelic loss and HRD also occur in primary nonbreast/ovarian tumors that arise in germline carriers.

Methods: A clinically ascertained cohort of carriers with a primary nonbreast/ovarian cancer was identified, including canonical (prostate and pancreatic cancers) and noncanonical (all other) tumor types.

Prostaglandins limit nuclear actin to control nucleolar function during oogenesis.

Prostaglandins (PGs), locally acting lipid signals, regulate female reproduction, including oocyte development. However, the cellular mechanisms of PG action remain largely unknown. One cellular target of PG signaling is the nucleolus.

High-fidelity laser-free universal control of trapped ion qubits.

Universal control of multiple qubits-the ability to entangle qubits and to perform arbitrary individual qubit operations-is a fundamental resource for quantum computing, simulation and networking. Qubits realized in trapped atomic ions have shown the highest-fidelity two-qubit entangling operations and single-qubit rotations so far. Universal control of trapped ion qubits has been separately demonstrated using tightly focused laser beams or by moving ions with respect to laser beams, but at lower fidelities.
