We present the first measurement of the missing energy due to nuclear effects in monoenergetic, muon neutrino charged-current interactions on carbon, originating from K^{+}→μ^{+}ν_{μ} decay at rest (E_{ν_{μ}}=235.5 MeV), performed with the J-PARC Sterile Neutrino Search at the J-PARC Spallation Neutron Source liquid scintillator based experiment. Toward characterizing the neutrino interaction, ostensibly ν_{μ}n→μ^{-}p or ν_{μ}^{12}C→μ^{-}^{12}N, we define the missing energy as the energy transferred to the nucleus (ω) minus the kinetic energy of the outgoing proton(s), E_{m}≡ω-∑T_{p}, and relate this to visible energy in the detector, E_{m}=E_{ν_{μ}}(235.

The Ξ_{b}^{0(-)}→Ξ_{c}(3055)^{+(0)}(→D^{+(0)}Λ)π^{-} decay chains are observed, and the spin-parity of Ξ_{c}(3055)^{+(0)} baryons is determined for the first time. The measurement is performed using proton-proton collision data at a center-of-mass energy of sqrt[s]=13 TeV, corresponding to an integrated luminosity of 5.4 fb^{-1}, recorded by the LHCb experiment between 2016 and 2018.

Importance: Overactive bladder (OAB) is a condition characterized by urinary urgency, frequency, and incontinence, affecting up to 43% of women. While treatment disparities are well-documented, this study sheds light on broader systemic barriers and the need for equitable approaches to improve diagnosis and management.
Objective: This study aimed to examine the types of OAB treatments (no treatment, pharmacotherapy, advanced therapy) received by patients in the United States, stratified by race, ethnicity, and socioeconomic factors, using data from the All of Us Research Hub.
Optical coating, an integral part of many optical systems, is prone to damage from environmental exposure and laser irradiation. This underscores the need for reliable and sensitive coating diagnostics. We introduce second harmonic generation (SHG) as a method for the sensitive detection of defects and inhomogeneities within optical thin films.

Background And Objectives: Primary care physician (PCP) shortages and uneven geographic distribution are well-documented. Black populations have less access to primary care and worse health outcomes, with a lack of provider-patient racial concordance playing a role. Addressing these disparities requires targeted approaches that produce more Black PCPs in high-need areas, including expanding community-based residency programs (CBRPs), which are more likely to produce physicians in high-need areas.
