Full Disclosure: Financial Statement Disclosures Under CERCLA [PDF]

open access: yes, 1993
This paper presents a comprehensive mathematical framework for depletion rate analysis and ties it to the physics of depletion. Theory was compared with empirical data from 1036 fields and a number of regions. Strong agreement between theory and practice

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Breakdown of field theory in near-horizon regions

open access: yesJournal of High Energy Physics
We discuss back-reaction in the semiclassical treatment of quantum fields near a black hole. When the state deviates significantly from Hartle-Hawking, simple energetic considerations of back-reaction give rise to a characteristic radial distance scale ∼

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Modular parallel transport of multiple intervals in 1+1-dimensional free fermion theory

open access: yesJournal of High Energy Physics, 2023
Modular parallel transport is a generalization of Berry phases, applied to modular (entanglement) Hamiltonians. Here we initiate the study of modular parallel transport for disjoint field theory regions.

An inductive theory of regional development

open access: yesPapers in Regional Science, 1993
Regional development tendencies in Western Europe in recent decades are analyzed. They show a mosaic-like pattern of dynamic and declining regions in all parts of Europe, while there is no uniform core/periphery polarization. On this basis, an inductive theory of regional development in economically advanced societies is constructed. It states that the

D-brane Spectrum and K-theory Constraints of D=4, N=1 Orientifolds [PDF]

open access: yes, 2006
We study the spectrum of stable BPS and non-BPS D-branes in Z_2 x Z_2 orientifolds for all choices of discrete torsion between the orbifold and orientifold generators.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

A Dual Mind Approach to Understanding the Conscious Self and Its Treatment

open access: yesNeuroSci, 2021
In this paper I will address questions about will, agency, choice, consciousness, relevant brain regions, impacts of disorders, and their therapeutics, and I will do this by referring to my theory, Dual-brain Psychology, which posits that within most of ...

Landau theory of phase separation in cuprates

open access: yes, 1994
I discuss the problem of phase separation in cuprates from the point of view of the Landau theory of Fermi liquids. I calculate the rate of growth of unstable regions for the hydrodymanics and collisionless limit and, in presence of long range Coulomb ...
