Join Radu Pop and Pietro Mele at Berlin Buzzwords as they discuss building an extensible hybrid search solution with Elasticsearch. They will cover functional modeling, cluster architecture, and practical insights on managing billions of vectors in real-world scenarios. Radu and Pietro will also address hybrid reranking challenges and the limitations of standard fusion techniques, explaining their innovative approach.

Koopman Operator Based Time-Delay Embeddings and State History Augmented LQR for Periodic Hybrid Systems: Bouncing Pendulum and Bipedal Walking
Time-delay embedding is a technique that uses snapshots of state history over time to build a linear state space model of a nonlinear smooth system. We demonstrate that periodic non-smooth or hybrid system can also be modeled as a linear state space system using this approach as long as its behavior is consistent in modes and timings. We extended time-delay embeddings to generate a linear model of two periodic hybrid systems: the bouncing pendulum and the simplest walker with control inputs. Th…

A coalition of European Union countries is pushing to bar Russian citizens who participated in the war against Ukraine from entering the Schengen Area, citing serious security concerns.
The call comes as Russia increased its hybrid operations targeting the European Union.
EU security agencies have repeatedly warned of Russian-linked sabotage operations, including arson attacks, orchestrated by Moscow as part of hybrid warfare strategies.
Interior ministers from the Baltic …

Baltics, Nordics, Poland propose Schengen ban for Russians who fought in Ukraine
"There are hundreds of thousands of Russian citizens who have fought against Ukraine," Estonian Interior Minister Lauri Laanemets said. "We must take a clear stance, these individuals cannot freely travel across Schengen."

Distortion-Aware Hybrid Beamforming for Integrated Sensing and Communication
This paper investigates a practical partially-connected hybrid beamforming transmitter for integrated sensing and communication (ISAC) with distortion from nonlinear power amplification. For this ISAC system, we formulate a communication rate and sensing mutual information maximization problem driven by our distortion-aware hybrid beamforming design. To address this non-convex problem, we first solve for a fully digital beamforming matrix by alternatively solving three sub-problems using manifo…

Hybrid Classical-Quantum Rainbow Table Attack on Human Passwords
Passwords that are long and human-generated pose a challenge for both classical and quantum attacks due to their irregular structure and large search space. In this work, we present an enhanced classical-quantum hybrid attack tailored to this scenario. We build rainbow tables using dictionary-based password generation with transformation rules to better model real user behavior. These tables are then organized into buckets, enabling faster lookup and reduced space complexity. To perform quantum…

A "Faux-Shock" Method for Hybrid Simulations of Astrophysical Shocks
We demonstrate a novel setup for hybrid particle-in-cell simulations designed to isolate the physics of the shock precursor over long time periods for significantly lower computational cost than previous methods. This is achieved using a "faux-shock" or shock-like boundary condition on one edge of our simulation domain such that particles that interact with the boundary either pass through it or are reflected off of it with a change in momentum that mimics scattering in the downstream. We show …

A 21-DOF Humanoid Dexterous Hand with Hybrid SMA-Motor Actuation: CYJ Hand-0
CYJ Hand-0 is a 21-DOF humanoid dexterous hand featuring a hybrid tendon-driven actuation system that combines shape memory alloys (SMAs) and DC motors. The hand employs high-strength fishing line as artificial tendons and uses a fully 3D-printed AlSi10Mg metal frame designed to replicate the skeletal and tendon-muscle structure of the human hand. A linear motor-driven module controls finger flexion, while an SMA-based module enables finger extension and lateral abduction. These modules are int…
