Initial State Privacy of Nonlinear Systems on Riemannian Manifolds

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In this paper, we investigate initial state privacy protection for discrete‐time nonlinear closed systems. By capturing Riemannian geometric structures inherent in such privacy challenges, we refine the concept of differential privacy through the introduction of an initial state adjacency set based on Riemannian distances.

Machine learning‐driven advances in carbon‐based quantum dots: Opportunities accompanied by challenges

Responsive Materials, EarlyView.
Machine learning provides a unifying framework to connect structure, fluorescence properties, and applications of carbon‐based quantum dots. This review highlights how data‐driven strategies enable fluorescence regulation, reveal underlying mechanisms, and accelerate the rational design of functional carbon dots.

Nonequilibrium Dynamics in Low Dimensional Systems

, 2001
In these lectures we give an overview of nonequilibrium stochastic systems. In particular we discuss in detail two models, the asymmetric exclusion process and a ballistic reaction model, that illustrate many general features of nonequilibrium dynamics ...

Splitting of Conditional Expectations and Liftings in Product Spaces II

Axioms
Let (X,A,P) and (Y,B,Q) be two probability spaces, R be their skew product on the product σ-algebra A⊗B and {(Ay,Sy):y∈Y} be a Q-disintegration of R. Then, let A⋇B be the σ-algebra generated A⊗B and by the family M:={E⊂X×Y:∃N∈B0∀y∉NSy^(Ey)=0} and R⋇ be ...

Confidence intervals for extinction risk: Validating population viability analysis with limited data

Methods in Ecology and Evolution, EarlyView.
Abstract The assessment of extinction risk remains a key component of IUCN and CITES evaluations. However, it has been argued that, under realistic data limitations, confidence intervals (CIs) for extinction probability often span the entire 0–1 range, rendering such assessments meaningless.

Why did Putin invade Ukraine? A theory of degenerate autocracy

American Journal of Political Science, EarlyView.
Abstract Many dictatorships end up with a series of disastrous decisions such as Hitler's attack on the Soviet Union or Saddam Hussein's aggression against Kuwait. Even if a certain policy choice is not ultimately fatal for the regime, such as Mao's Big Leap Forward or the Pol Pot's collectivization drive, they typically involve both a miscalculation ...

Neural Local Inter‐reflection Modeling for Garment Fold Rendering

Computer Graphics Forum, EarlyView.
Abstract Realistic garment rendering requires simulating complex multi‐bounce light paths within intricate fold geometries. In these regions, conventional path tracing is computationally expensive as light becomes trapped, necessitating high bounce counts for convergence.

Survey on differential estimators for 3d point clouds

Computer Graphics Forum, EarlyView.
Abstract Recent advancements in 3D scanning technologies, including LiDAR and photogrammetry, have enabled the precise digital replication of real‐world objects. These methods are widely used in fields such as GIS, robotics, and cultural heritage. However, the point clouds generated by such scans are often noisy and unstructured, posing challenges for ...
