Almost Settling the Hardness of Noncommutative Determinant [PDF]
, 2011 In this paper, we study the complexity of computing the determinant of a matrix over a non-commutative algebra. In particular, we ask the question, "over which algebras, is the determinant easier to compute than the permanent?" Towards resolving this ...

Determinant of a new fermionic action on a lattice - (I) [PDF]
, 2000 We investigate, analytically and numerically, the fermion determinant of a new action on a (1+1)-dimensional Euclidean lattice. In this formulation the discrete chiral symmetry is preserved and the number of fermion components is a half of that of Kogut ...

High-dimensional covariance estimation by minimizing ℓ1-penalized log-determinant divergence [PDF]
, 2008 Given i.i.d. observations of a random vector X 2 R p , we study the problem of estimating both its covariance matrix ∗ , and its inverse covariance or concentration matrix ∗ = ( ∗ ) −1 .

Environmental Health and Preventive Medicine, 2022 Background: COVID-19 pandemic is tremendously impacted by socioeconomic and health determinants worldwide. This study aimed to determine factors associated with COVID-19 fatality among member states and partner countries of the Organization for Economic ...

Determinants of confirmation [PDF]
Psychonomic Bulletin & Review, 2007 Epistemologists often suppose that the extent to which evidence e confirms hypothesis H depends on probabilities involving e and H, and nothing more. We show experimentally that human reasoners sometimes violate this assumption.

Determining Environmental Determinism
Progress in Human Geography, 2012 This commentary is a direct response to the Forum article ‘Environmentalist thinking and/in geography’ by Radcliffe et al. (2010) . Two main problems are addressed: the perpetuation of a false analogy between cultural and biological evolution, and a misunderstanding of memes.

The boundary of the orbit of the 3 by 3 determinant polynomial [PDF]
, 2016 We consider the 3 by 3 determinant polynomial and we describe the limit points of the set of all polynomials obtained from the determinant polynomial by linear change of variables. This answers a question of J.

The phospholipid PI(3,4)P2 is an apical identity determinant
Nature Communications, 2018 Apical-basal polarization is essential for epithelial tissue formation, segregating cortical domains to perform distinct physiological functions. Cortical lipid asymmetry has emerged as a determinant of cell polarization.

On the expressive power of read-once determinants
, 2015 We introduce and study the notion of read-$k$ projections of the determinant: a polynomial $f \in \mathbb{F}[x_1, \ldots, x_n]$ is called a {\it read-$k$ projection of determinant} if $f=det(M)$, where entries of matrix $M$ are either field elements or ...
