Joint Angle and Velocity-Estimation for Target Localization in Bistatic mmWave MIMO Radar in the Presence of Clutter
Sparse Bayesian learning (SBL)-aided target localization is conceived for a bistatic mmWave MIMO radar system in the presence of unknown clutter, followed by the development of an angle-Doppler (AD)-domain representation of the target-plus-clutter echo model for accurate target parameter estimation. The proposed algorithm exploits the three-dimensional (3D) sparsity arising in the AD domain of the scattering scene and employs the powerful SBL framework for the estimation of target parameters, s…

Conspiracy theory participation expands as research reveals participatory culture appeal
A five-year study dispels the stereotype of conspiracy theorists as angry loners or keyboard warriors. Rather, social and emotional connections provided by conspiracy theorists are recruiting diverse participants on a growing scale.

A Practical Guide to using Pauli Path Simulators for Utility-Scale Quantum Experiments
In this this paper we present an inexpensive protocol to perform runtime and memory estimation for large-scale experiments with Pauli Path simulators (PPS). Additionally, we propose a conceptually simple solution for studying whether PPS can be used as a scientific discovery tool, rather than reproducing existing answers. We start by analyzing the dynamics of the Pauli coefficients tracked in the Heisenberg picture. In addition to surprisingly generic convergence features of the Pauli coefficie…

Aerodynamics and Aeroacoustics of da Vinci's Aerial Screw
Leonardo da Vinci's aerial screw, conceived in the 15th century, represents one of the earliest conceptualizations of lift-generating rotary flight. Despite its historical significance, the aerodynamic and aeroacoustic performance of this rotor has received limited scientific attention. In this study, we employ direct numerical simulations to analyze the aerodynamic forces and acoustic emissions of a modernized da Vinci aerial screw design across a range of Reynolds numbers (2000, 4000, and 800…

Evasive Ransomware Attacks Using Low-level Behavioral Adversarial Examples
Protecting state-of-the-art AI-based cybersecurity defense systems from cyber attacks is crucial. Attackers create adversarial examples by adding small changes (i.e., perturbations) to the attack features to evade or fool the deep learning model. This paper introduces the concept of low-level behavioral adversarial examples and its threat model of evasive ransomware. We formulate the method and the threat model to generate the optimal source code of evasive malware. We then examine the method u…

I just took a look at the proposed text for these "trump accounts".
The language begins at page 741 in the linked-to .pdf file, below.
The language is rather vague. For example, it does not indicate the base date for measuring the age of the "beneficiary". Is it the conception date or the live-birth date?
And the text is filled with terribly vague phrases like "Rules similar to the rules of section" - There are big devils lurking in that hor…

Trump to promote $1,000 ‘Trump Accounts’ for newborns at White House event
President Donald Trump is set to host a roundtable at the White House on Monday to promote a key feature of the sweeping Republican domestic policy bill – a provision that would provide every American newborn with a $1,000 investment account, a White House official told CNN.

Entangled Polariton States in the Visible and Mid-Infrared Spectral Ranges
Entanglement generation in polariton systems is fundamentally constrained by high losses and decoherence, which typically outweigh polariton nonlinearities. Here, we propose a conceptually different approach that uses optomechanical interactions, rather than polariton-polariton interactions, to generate entangled polaritons. Our double-resonant scheme relies on strong exciton-phonon coupling, found in both inorganic and molecular semiconductors, enabling room-temperature generation of spectrall…

On something and nothing: The interface of two types of nothing
We suggest that the question of why is there something rather than nothing can be answered by the existence of two types of nothing. We propose that matter occurs at the boundaries of intersection of both nothings. This accords with the common view that there are three worlds; the platonic world of concepts, the material world (i.e. of matter), and the non-material world (i.e. of consciousness). Both the material and non-material worlds have their own type of nothing, thus leading to the propos…

Exploiting Cognition in ISAR Processing for Spectral Compatibility Applications
This paper introduces and analyzes the concept of a cognitive inverse synthetic aperture radar (ISAR) ensuring spectral compatibility in crowded electromagnetic environments. In such a context, the proposed approach alternates between environmental perception, recognizing possible emitters in its frequency range, and an action stage, synthesizing and transmitting a tailored radar waveform to achieve the desired imaging task while guaranteeing spectral coexistence with overlaid emitters. The per…

mmFlux: Crowd Flow Analytics with Commodity mmWave MIMO Radar
In this paper, we present a novel framework for extracting underlying crowd motion patterns and inferring crowd semantics using mmWave radar. First, our proposed signal processing pipeline combines optical flow estimation concepts from vision with novel statistical and morphological noise filtering to generate high-fidelity mmWave flow fields - compact 2D vector representations of crowd motion. We then introduce a novel approach that transforms these fields into directed geometric graphs, where…
