Automating Sensor Characterization with Bayesian Optimization
The development of novel instrumentation requires an iterative cycle with three stages: design, prototyping, and testing. Recent advancements in simulation and nanofabrication techniques have significantly accelerated the design and prototyping phases. Nonetheless, detector characterization continues to be a major bottleneck in device development. During the testing phase, a significant time investment is required to characterize the device in different operating conditions and find optimal ope…

PSA about food labeling in the US
We have a gluten detection service dog because many things that should be gluten free/say they’re gluten free are not actually gluten free.
Stuff gets contaminated when growing (e.g. next to wheat field), by shared equipment, in factories, from packaging, during transport and in-store.
Every US consumer should know:
1. The list of ingredients on food isn't exhaustive
2. Allergen labeling:
a) limited to just some allergens
b) manufacturers don't actually have to test
c) "certified" foods are tested—but not continuously
d) testing only works with enough contamination
Some certifications may require batch-testing, but usually they don't.
A "certified gluten free" product may e.g. contain oats which sometimes are contaminated with gluten—but as not every batch is tested it's impossible to know unless you test yourself (hence the service dog).
Even if the product is properly batch-tested, you might get a part of the product that has the allergen in it, whereas the tested part didn't.
Or the threshold was too low (our dog can detect gluten better than any available lab testing equipment; yes, dogs are amazing).
Food products also contain ingredients that do not have to be included on the label when they're "incidental" (included in an another ingredient) or if they're considered part of the manufacturing process but not of the final product (e.g. various coatings on factory equipment).
Don't need to list flavors or specific spices either. ¯\_(ツ)_/¯
As for allergens, only those responsible for ~90% of food allergies* have to be specifically declared, and they're not tested for as it's simply based on the ingredients list.
Good luck if you have other allergies.

Asteroseismic investigation of HD 140283: The Methuselah star
HD 140283 is a well-studied metal-poor subgiant and a Gaia benchmark star, often used for testing stellar models due to its proximity, brightness, and low metallicity ([Fe/H] = -2.3 dex). Here we present the first asteroseismic analysis of HD 140283, providing improved constraints on its fundamental properties. The star was observed by TESS in 20-second cadence during Sector 51. We extracted a custom light curve and performed a frequency analysis, revealing a rich spectrum of solar-like osc…

Testing Lens Models of PLCK G165.7+67.0 Using Lensed SN H0pe
Supernova H0pe is a multiply-imaged Type Ia supernova (SN Ia) and the second lensed SN to yield a measurement of the Hubble constant by the time-delay cosmography method, finding $H_0 = 75.4^{+8.1}_{-5.5} \text{km s}^{-1} \text{Mpc}^{-1}$. We investigate the seven lens modeling approaches used to derive $H_0$, assessing their agreement with $Λ\text{CDM}$ constraints from SN Ia surveys through a purely observational comparison. While photometrically derived magnifications yield distance moduli …

Improving Sensitivity in A/B Tests: Integrating CUPED with Trimmed Mean Techniques
Accurate estimation of treatment effects in online A/B testing is challenging with zero-inflated and skewed metrics. Traditional tests, like Welch's t-test, often lack sensitivity with heavy-tailed data due to their reliance on means, as opposed to e.g., percentiles. The Controlled Experiments Using Pre-experiment Data (CUPED) technique improves sensitivity by reducing variance, yet that variance reduction is insufficient for highly skewed metrics. Alternatively, Yuen's t-test uses trimmed mean…

An Ultra-Short Period Super-Earth and Sub-Neptune Spanning the Radius Valley Orbiting the Kinematic Thick Disk Star TOI-2345
A crucial chemical link between stars and their orbiting exoplanets is thought to exist. If universal, this connection could affect the formation and evolution of all planets. Therefore, this potential vital link needs testing by characterising exoplanets around chemically-diverse stars. We present the discovery of two planets orbiting the metal-poor, kinematic thick-disk K-dwarf TOI-2345. TOI-2345 b is a super-Earth with a period of 1.05 days and TOI-2345 c is a sub-Neptune with a period of 21…

WALLABY Pilot Survey: Characterizing Low Rotation Kinematically Modelled Galaxies
Many of the tensions in cosmological models of the Universe lie in the low mass, low velocity regime. Probing this regime requires a statistically significant sample of galaxies with well measured kinematics and robustly measured uncertainties. WALLABY, as a wide area, untargetted HI survey is well positioned to construct this sample. As a first step towards this goal we develop a framework for testing kinematic modelling codes in the low resolution, low $S/N$, low rotation velocity regime. We …

Detection of Chagas Disease from the ECG: The George B. Moody PhysioNet Challenge 2025
Objective: Chagas disease is a parasitic infection that is endemic to South America, Central America, and, more recently, the U.S., primarily transmitted by insects. Chronic Chagas disease can cause cardiovascular diseases and digestive problems. Serological testing capacities for Chagas disease are limited, but Chagas cardiomyopathy often manifests in ECGs, providing an opportunity to prioritize patients for testing and treatment. Approach: The George B. Moody PhysioNet Challenge 2025 invites …

MUSE: Multi-Treatment Experiment Design for Winner Selection and Effect Estimation
We study the design of experiments with multiple treatment levels, a setting common in clinical trials and online A/B/n testing. Unlike single-treatment studies, practical analyses of multi-treatment experiments typically first select a winning treatment, and then only estimate the effect therein. Motivated by this analysis paradigm, we propose a design for MUlti-treatment experiments that jointly maximizes the accuracy of winner Selection and effect Estimation (MUSE). Explicitly, we introduce …

We present the first measurement of the sky-projected orbital obliquity of a benchmark transiting brown dwarf host, HIP 33609, as a part of the Orbital Architectures of Transiting Massive Exoplanets And Low-mass stars (OATMEAL) survey. HIP 33609 b is a highly eccentric, 68 $M_{\rm J}$ brown dwarf orbiting a 10,300 K, A-type star with an orbital period of 39 days. Its host star is a known member of the 150 Myr old MELANGE-6 moving group, making it an excellent laboratory for testing sub-stellar …
