Boosting Vision Semantic Density with Anatomy Normality Modeling for Medical Vision-language Pre-training
Vision-language pre-training (VLP) has great potential for developing multifunctional and general medical diagnostic capabilities. However, aligning medical images with a low signal-to-noise ratio (SNR) to reports with a high SNR presents a semantic density gap, leading to visual alignment bias. In this paper, we propose boosting vision semantic density to improve alignment effectiveness. On one hand, we enhance visual semantics through disease-level vision contrastive learning, which strengthe…

High-fidelity two-qubit gates with transmon qubits using bipolar flux pulses and tunable couplers
High-fidelity two-qubit gates are essential for scalable quantum computing. We present a scheme based on superconducting transmon qubits and a control pulse delivery protocol that enables arbitrary controlled-phase gates modulated solely by an independent arbitrary waveform generator pulse. We combined a tunable coupler design with bipolar flux-pulsing to demonstrate a high-fidelity gate with a performance of $99.5\%$. Our gates inherit the advantages of both approaches: minimal residual ZZ cou…

Enabling Security on the Edge: A CHERI Compartmentalized Network Stack
The widespread deployment of embedded systems in critical infrastructures, interconnected edge devices like autonomous drones, and smart industrial systems requires robust security measures. Compromised systems increase the risks of operational failures, data breaches, and -- in safety-critical environments -- potential physical harm to people. Despite these risks, current security measures are often insufficient to fully address the attack surfaces of embedded devices. CHERI provides strong se…

Robust surface superconductivity and vortex lattice in the Weyl semimetal $γ$-PtBi$_2$
The layered compound $γ$-PtBi$_2$ is a topological semimetal with Fermi arcs at the surface joining bulk Weyl points. Recent work has found a peculiar surface superconducting state with a critical temperature two orders of magnitude larger than the bulk value. However, no superconducting vortices have been identified, raising questions about the robustness of the phase coherence in this new surface superconducting state. Here we measure the superconducting gap and visualize the vortex lattice …

Physics-Informed Detection of Friction Anomalies in Satellite Reaction Wheels
As the number of satellites in orbit has increased exponentially in recent years, ensuring their correct functionality has started to require automated methods to decrease human workload. In this work, we present an algorithm that analyzes the on-board data related to friction from the Reaction Wheel Assemblies (RWA) of a satellite and determines their operating status, distinguishing between nominal status and several possible anomalies that require preventive measures to be taken. The algorit…

Boosting the NOx production in microwave air plasma: A synergy of chemistry and vibrational kinetics
This study employs a quasi-1.5D multi-temperature model to investigate the mechanisms governing NOx production and energy costs in microwave plasma reactors operating at 80 mbar, focusing on the interplay of vibrational, chemical and electron kinetics, thermodynamics, and transport processes across the discharge and afterglow. In the plasma discharge zone, non-thermal processes enhance NOx production as electrons transfer energy effectively to the vibrational mode of N2. However, the non-therma…

Red Teaming for Generative AI, Report on a Copyright-Focused Exercise Completed in an Academic Medical Center
Generative AI is present in multiple industries. Dana-Farber Cancer Institute, in partnership with Microsoft, has created an internal AI tool, GPT4DFCI. Together we hosted a red teaming event to assess whether the underlying GPT models that support the tool would output copyrighted data. Our teams focused on reproducing content from books, news articles, scientific articles, and electronic health records. We found isolated instances where GPT4DFCI was able to identify copyrighted material and r…
