3D Reconstruction with Uncalibrated Cameras Using the Six-Line Conic Variety

open access: yes, 2008
We present new algorithms for the recovery of the Euclidean structure from a projective calibration of a set of cameras with square pixels but otherwise arbitrarily varying intrinsic and extrinsic parameters.

A Berger type normal holonomy theorem for complex submanifolds [PDF]

open access: yes, 2010
We prove a kind of Berger-Simons' Theorem for the normal holonomy group of a complex submanifold of the projective ...

Dynamics of real projective transformations

open access: yesApplied General Topology, 2018
The dynamics of a projective transformation on a real projective space are studied in this paper. The two main aspects of these transformations that are studied here are the topological entropy and the zeta function.

Projective and other locative PPs in Greek

open access: yesGlossa, 2022
The distinction between projective and non-projective locative prepositions that has been proposed in the semantic literature (Zwarts & Winter 2000) is reflected in the syntax and morphology of Greek spatial expressions.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Projective Space: Structuring a Beholder’s Imaginative Response [PDF]

open access: yes, 2009
The thesis explores the reciprocal relationship between an artwork and the space of its reception. It proposes a distinctive position on spatiality and the virtual. The thesis is submitted in two parts: a written thesis (Part One), and a documentation of

A Dual of the Chow Transformation

open access: yesComplex Manifolds, 2018
We define a dual of the Chow transformation of currents on the complex projective space. This transformation factorizes a left inverse of the Chow transformation and its composition with the Chow transformation is a right inverse of a linear diferential ...

Rigidity through a Projective Lens

open access: yesApplied Sciences, 2021
In this paper, we offer an overview of a number of results on the static rigidity and infinitesimal rigidity of discrete structures which are embedded in projective geometric reasoning, representations, and transformations.

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics
