Critically endangered chameleon discovered outside its known habitat in Madagascar
ANTANANARIVO — At the end of April, a team of researchers scouring a scarred area of spiny forest in southwestern Madagascar came across three individuals of a critically endangered chameleon species. Furcifer belalandaensis had not previously been recorded outside of a tiny, 4-square-kilometer (1.5-square-mile) area near the village of Belalanda after which it’s named, so […]

Causal Effect Identification in lvLiNGAM from Higher-Order Cumulants
This paper investigates causal effect identification in latent variable Linear Non-Gaussian Acyclic Models (lvLiNGAM) using higher-order cumulants, addressing two prominent setups that are challenging in the presence of latent confounding: (1) a single proxy variable that may causally influence the treatment and (2) underspecified instrumental variable cases where fewer instruments exist than treatments. We prove that causal effects are identifiable with a single proxy or instrument and provide…

Infinitesimal freeness for orthogonally invariant random matrices
We introduce a new kind of free independence, called real infinitesimal freeness. We show that independent orthogonally invariant with infinitesimal laws are asymptotically real infinitesimally free. We introduce new cumulants, called real infinitesimal cumulants and show that real infinitesimal freeness is equivalent to vanishing of mixed cumulants. We prove the formula for cumulants with products as entries.

Many thanks to Michael Daniel of the Cyber Threat Alliance and Mark Montgomery of FDD for their help and insight.
Daniel made a point about Trump's cutbacks on cyber spending, a situation that most cyber folks haven't see…

A Novel Approach to Fast Calculation of High-Order Q-Cumulants
The method of Q-cumulants has been shown as a powerful tool to study the fine details of the azimuthal anisotropies in high-energy nucleus-nucleus collisions. A new method for the fast calculation of arbitrary order Q-cumulant v_{n}\{2k\} values, based on the partition of a non-negative integer l $\le$ m for calculation of the 2m-particle azimuthal correlations is presented in this paper. Unlike the standard Q-cumulants method in which the calculation of high-order multi-particle calculations i…

Measurement of the longitudinal flow-plane decorrelation using multi-plane cumulants in sqrt(s_NN) = 200 GeV Au+Au, Ru+Ru, and Zr+Zr collisions
Measurements of the variation of anisotropic flow-plane angles (Psi_n) with rapidity, commonly known as flow-plane decorrelation, provide important insights into the initial conditions of the matter produced in heavy-ion collisions. In this paper, using data collected by the STAR experiment, we report the first measurement of the four-plane cumulant observable T_n{ba;dc} = <>, where superscripts a, b, c, and d denote sequential regions in pse…

Large time cumulants of the KPZ equation on an interval
We consider the Kardar-Parisi-Zhang equation on the interval $[0,L]$ with Neumann type boundary conditions and boundary parameters $u,v$. We show that the $k$-th order cumulant of the height behaves as $c_k(L,u,v)\, t$ in the large time limit $t \to +\infty$, and we compute the coefficients $c_k(L,u,v)$. We obtain an expression for the upper tail large deviation function of the height. We also consider the limit of large $L$, with $u=\tilde u/\sqrt{L}$, $u=\tilde v/\sqrt{L}$, which should give …

CHIP: Chameleon Hash-based Irreversible Passport for Robust Deep Model Ownership Verification and Active Usage Control
The pervasion of large-scale Deep Neural Networks (DNNs) and their enormous training costs make their intellectual property (IP) protection of paramount importance. Recently introduced passport-based methods attempt to steer DNN watermarking towards strengthening ownership verification against ambiguity attacks by modulating the affine parameters of normalization layers. Unfortunately, neither watermarking nor passport-based methods provide a holistic protection with robust ownership proof, hig…
