Epidemiologists have access to various methods to reduce bias and improve statistical efficiency in effect estimation, from standard multivariable regression to state-of-the-art doubly-robust efficient estimators paired with highly flexible, data-adaptive algorithms ("machine learning"). However, due to numerous assumptions and trade-offs, epidemiologists face practical difficulties in recognizing which method, if any, may be suitable for their specific data and hypotheses. Importantly, relative advantages are necessarily context-specific (data structure, algorithms, model misspecification), limiting the utility of universal guidance.

This paper presents the novel design of a printed, low-cost, dual-port, and dual-polarized slot antenna for microwave biomedical radars. The butterfly shape of the radiating element, with orthogonally positioned arms, enables simultaneous radiation of both vertically and horizontally polarized waves. The antenna is intended for full-duplex in-band applications using two mutually isolated antenna ports, with the CPW port on the same side of the substrate as the slot antenna and the microstrip port positioned orthogonally on the other side of the substrate.

The first experimental formation of thiocarbonic acid (HCS) is presented in this work from low-temperature interstellar ice analogs composed of hydrogen sulfide (HS) and carbon disulfide (CS) exposed to electron irradiation simulating the impact of galactic cosmic rays (GCRs) on interstellar ices. The recent attention brought to sulfur-bearing molecules, as well as the recent detection of carbonic acid (HCO) in the interstellar medium (ISM), invites the study of the interstellar detection of the sulfur counterpart, thiocarbonic acid. However, the interstellar formation pathways of thiocarbonic acid have remained elusive.

Carbonyl sulfide (OCS) is currently the only securely detected sulfur-bearing species in interstellar ices, making it an ideal window into solid-state sulfur chemistry in dense star-forming regions. Previous astronomical observations of the OCS asymmetric stretching mode (ν) at ∼2040 cm (∼4.9 μm) demonstrate that interstellar OCS may be embedded in CHOH-rich ices, indicating that OCS likely forms in the coldest, densest parts of star-forming regions where catastrophic CO freezeout occurs.

The formation and characterization of hydrogen trioxide have fascinated scientists for more than a century, due to its role as a prototype model for oxygen-chain bonding and as a key transient in antibody-catalyzed oxidation reactions relevant to the origin of life. However, the abiotic formation pathways to hydrogen trioxide have remained elusive. Here, we demonstrate in laboratory simulation experiments that hydrogen trioxide effectively forms in water-molecular oxygen ice analogs at temperatures as low as 5 kelvin under exposure to proxies of galactic cosmic rays.
