Accurate outcome and exposure ascertainment in electronic health record (EHR) data, referred to as EHR phenotyping, relies on the completeness and accuracy of EHR data for each individual. However, some individuals, such as those with a greater comorbidity burden, visit the health care system more frequently and thus have more complete data, compared with others. Ignoring such dependence of exposure and outcome misclassification on visit frequency can bias estimates of associations in EHR analysis.

This Letter presents the first study of Higgs boson production in association with a vector boson (V=W or Z) in the fully hadronic qqbb final state using data recorded by the ATLAS detector at the LHC in proton-proton collisions at sqrt[s]=13  TeV and corresponding to an integrated luminosity of 137  fb^{-1}. The vector bosons and Higgs bosons are each reconstructed as large-radius jets and tagged using jet substructure techniques. Dedicated tagging algorithms exploiting b-tagging properties are used to identify jets consistent with Higgs bosons decaying into bb[over ¯].

Article Synopsis
  • Scientists used special techniques to study how glucose is used in cells that help control insulin, called β cells, in both mice and humans.
  • They discovered that glucose is used similarly in both species, but humans produce much more lactate, which is a waste product.
  • A specific protein called LDHB helps control how much lactate these cells make, and lower levels of this protein are linked to higher insulin levels in humans.

Desire discrepancies are a common source of relationship conflict and one reason adults may seek couples counseling. Within romantic relationships, adults individually experience sexual and affectionate desire, but also experience desire relative to their partner. If desire discrepancies exist, partners may attempt to resolve these discrepancies.

Research suggests that COVID-19-related restrictions affected individuals' ability to engage in relationship maintenance behaviors and have led to poorer romantic relationship quality. Poor relationship quality may be especially problematic for lesbian, gay, bisexual, transgender, queer or questioning, and otherwise non-heterosexual or-cisgender (LGBTQ+) college students, who often lack family support and are at greater risk for mental health issues. We used a social exchange theory lens to examine correlates of relationship satisfaction for LGBTQ+ college students during the early months of the pandemic.

Article Synopsis
  • The study aims to establish an enzyme-driven bioleaching pathway for extracting copper, focusing on the Type-1 copper protein rusticyanin from Acidithiobacillus ferrooxidans (AfR).
  • Comparisons were made with an ancestral form of rusticyanin (N0) and an archaeal version from Ferroplasma acidiphilum (FaR), revealing that while N0 and FaR have similar redox potentials to AfR, their electron transport rates are significantly slower.
  • The findings indicate that AfR has evolved for efficient energy conversion during iron oxidation, and newly observed behavior of AfR involves a partially unfolded state, which could affect its stability and has implications for optimizing it for bioleaching applications.

Optogenetics allows manipulation of neural circuits with high spatial and temporal precision. However, combining this precision with control over a significant portion of the brain is technologically challenging (especially in larger animal models). Here, we have developed, optimised, and tested in vivo, the Utah Optrode Array (UOA), an electrically addressable array of optical needles and interstitial sites illuminated by 181 µLEDs and used to optogenetically stimulate the brain.

Article Synopsis
  • Frontotemporal lobar degeneration (FTLD) is a rare condition characterized by behavioral and motor symptoms, making traditional neuropsychological assessments less effective for early detection; smartphone-based cognitive tests may provide a solution for remote evaluations.
  • A study conducted over four years involved 360 participants with varying stages of FTLD using smartphone apps to assess cognitive function, splitting them into discovery and validation groups, with a majority being asymptomatic or at preclinical stages.
  • Results indicate the smartphone-based tests showed moderate to excellent reliability in measuring cognitive function, suggesting they could serve as valid tools for remote assessments in FTLD patients.
