Understanding the Burden of Orofacial Involvement and Patient Treatment Preferences in Systemic Sclerosis: Results From a Large International Survey

open access: yesArthritis Care &Research, EarlyView.
Objective Orofacial manifestations are significantly impactful in patients with systemic sclerosis (SSc) yet remain understudied, with no dedicated clinical guidelines to inform their management. Methods An international online survey comprised38 questions addressing orofacial manifestations of SSc, including patients’ confidence in their treating ...

Flexural Behavior of 3D‐Printed Porous Bouligand‐Structured Polymers: Influence of Pitch Angle and Porosity

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight

Understanding public attitudes toward restrictive voting laws in the United States

open access: yesResearch & Politics, 2023
Existing research on voting legislation argues that Republican lawmakers enact strict voting laws as part of a racialized, partisan electoral strategy—they believe that the laws will reduce minority turnout and benefit Republicans electorally.

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Will Concurrent Elections Reshape the Electorate?

open access: yesCalifornia Journal of Politics and Policy, 2020
In 2015, Governor Jerry Brown signed the California Voter Participation Rights Act (SB 415) into law.  As its title suggests, the bill aimed to increase turnout in local elections by forcing all California jurisdictions to hold elections concurrently ...

Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

open access: yesAdvanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Electoral Arrangements and Turnout Variance at the Sub-National Level: Comparative Insights from Three Constituencies in Ghana

open access: yesModern Africa, 2020
Using micro-level data from three constituencies in Ghana, which are cases of high, average and low turnout respectively, I assess whether voters’ perceptions of the cost of voting (resource and time) can explain such variation in voter turnout.
