Understanding wrist skin temperature changes to hormone variations across the menstrual cycle.

Consumer devices are increasingly used to monitor peripheral body temperature (PBT) for menstrual cycle tracking, but the link between PBT and hormone variations remains underexplored. This study examines the relationship between these variables with a focus on nightly wrist skin temperature (WST). Fifty participants provided physiological and self-reported data, including WST, daily step counts, glucose levels, hormone levels (E3G, LH), and diary entries.

Blood glucose variance measured by continuous glucose monitors across the menstrual cycle.

Past studies on how blood glucose levels vary across the menstrual cycle have largely shown inconsistent results based on limited blood draws. In this study, 49 individuals wore a Dexcom G6 continuous glucose monitor and a Fitbit Sense smartwatch while measuring their menstrual hormones and self-reporting characteristics of their menstrual cycles daily. The average duration of participation was 79.

VisTA: Integrating Machine Intelligence with Visualization to Support the Investigation of Think-Aloud Sessions.

Think-aloud protocols are widely used by user experience (UX) practitioners in usability testing to uncover issues in user interface design. It is often arduous to analyze large amounts of recorded think-aloud sessions and few UX practitioners have an opportunity to get a second perspective during their analysis due to time and resource constraints. Inspired by the recent research that shows subtle verbalization and speech patterns tend to occur when users encounter usability problems, we take the first step to design and evaluate an intelligent visual analytics tool that leverages such patterns to identify usability problem encounters and present them to UX practitioners to assist their analysis.

Proton disorder in a short intramolecular hydrogen bond investigated by single-crystal neutron diffraction at 2.5 and 170 K.

The substituted acetylacetone 3-[2-(pyridin-4-yl)ethyl]pentane-2,4-dione, CHNO, (1), with an ethylene bridge between the acetylacetone moiety and the heteroaromatic ring, represents an attractive linker for mixed-metal coordination polymers. In the crystal, (1) adopts an antiperiplanar conformation with respect to the C-C bond in the central ethylene group and almost coplanar acetylacetone and pyridyl groups. The ditopic molecule exists as the enol tautomer, with proton disorder in the short intramolecular hydrogen bond.

3-(Pyridin-4-yl)acetylacetone: a donor ligand towards mercury(II) halides and a versatile linker for complex materials.

The ditopic organic molecule 3-(pyridin-4-yl)acetylacetone (HacacPy) acts as a pyridine-type ligand towards HgX (X = Cl, Br, I). The nature of the anion and the ligand-to-cation ratio dominate the outcome of the reaction. Two different coordination compounds form with HgCl, namely a ligand-rich mononuclear complex, HgCl(HacacPy), and a ligand-deficient one-dimensional chain polymer, [Hg(μ-Cl)(HacacPy)], with five-coordinated Hg cations.

3-(Pyridin-4-yl)acetylacetone: Cd and Hg compete for nitrogen coordination.

3-(Pyridin-4-yl)acetylacetone (HacacPy) acts as a pyridine-type ligand towards Cd and Hg halides. With CdBr, the one-dimensional polymer [Cd(μ-Br)(HacacPy)Cd(μ-Br)(HacacPy)] is obtained in which five- and six-coordinated Cd cations alternate in the chain direction. Reaction of HacacPy with HgBr results in [Hg(μ-Br)Br(HacacPy)], a polymer in which each Hg centre is tetracoordinated.

A whole zoo of hydrogen bonds in one crystal structure: tris(isonicotinium) hydrogensulfate sulfate monohydrate.

Depending on the reaction partner, the organic ditopic molecule isonicotinic acid (Hina) can act either as a Brønsted acid or base. With sulfuric acid, the pyridine ring is protonated to become a pyridinium cation. Crystallization from ethanol affords the title compound tris(4-carboxypyridinium) hydrogensulfate sulfate monohydrate, 3CHNO·HSO·SO·HO or [(Hina)(HSO)(SO)(HO)].

Co-Designing Ambient Assisted Living (AAL) Environments: Unravelling the Situated Context of Informal Dementia Care.

Ambient assisted living (AAL) aims to help older persons "age-in-place" and manage everyday activities using intelligent and pervasive computing technology. AAL research, however, has yet to explore how AAL might support or collaborate with informal care partners (ICPs), such as relatives and friends, who play important roles in the lives and care of persons with dementia (PwDs). In a multiphase codesign process with six (6) ICPs, we envisioned how AAL could be situated to complement their care.

Barriers to acceptance of personal digital assistants for HIV/AIDS data collection in Angola.

Purpose: Handheld computers have potential to improve HIV/AIDS programs in healthcare settings in low-resource countries, by improving the speed and accuracy of collecting data. However, the acceptability of the technology (i.e.
