Opers and theta functions

open access: yesAdvances in Mathematics, 2004
We construct natural maps (the Klein and Wirtinger maps) from moduli spaces of vector bundles on an algebraic curve $X$ to affine spaces, as quotients of the nonabelian theta linear series. We prove a finiteness result for these maps over generalized Kummer varieties (moduli of torus bundles), leading us to conjecture that the maps are finite in ...

High‐Resolution Corrosion Fingerprinting of Alloy Libraries via Microdroplet Spectroelectrochemistry

open access: yesAdvanced Engineering Materials, EarlyView.
Ionic‐liquid microdroplet spectroelectrochemistry enables stable, localized electrochemical measurements over extended timescales. By coupling impedance spectroscopy, wetting analysis, finite‐element simulations, and operando Raman spectroscopy, it disentangles geometrical and electrochemical effects, opening new opportunities for rapid corrosion ...

Possible role of acetylcholine in regulating spatial novelty effects on theta rhythm and grid cells

open access: yesFrontiers in Neural Circuits, 2012
Pharmacological and lesion data indicate that acetylcholine plays an important role in memory formation. Increased levels of acetylcholine in the hippocampal formation are associated with successful encoding while disruption of the cholinergic system ...

Increased mesiotemporal delta activity characterizes virtual navigation in humans [PDF]

open access: yes, 2013
Hippocampal theta or rhythmic slow activity (RSA) occurring during exploratory behaviors and rapid-eye-movement (REM) sleep is a characteristic and well-identifiable oscillatory rhythm in animals.

Low β2 Main Peak Frequency in the Electroencephalogram Signs Vulnerability To Depression.

open access: yesFrontiers in Neuroscience, 2016

Quantum Super Theta Vectors and Theta Functions

open access: yesKyungpook mathematical journal, 2016
\textit{Y. Manin}'s constructions of quantum theta function and quantum theta vector [Lett. Math. Phys. 56, 295--320 (2001; Zbl 1081.14501)] are extended to the super tori. Classically, theta functions play the role of observables and states. However, in quantum mechanics, the roles of observables and states separated.

Algebras, Graphs and Thetas

open access: yesElectronic Notes in Theoretical Computer Science, 2019
We extend the clique-coclique inequality, previously known to hold for graphs in association schemes and vertex-transitive graphs, to graphs in homogeneous coherent configurations and 1-walk regular graphs. We further generalize it to a stronger inequality involving the Lovász theta number of such graphs, and some theta variants, including ...

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...
