Componentwise and Cartesian decompositions of linear relations

open access: yes, 2009
Let $A$ be a, not necessarily closed, linear relation in a Hilbert space $\sH$ with a multivalued part $\mul A$. An operator $B$ in $\sH$ with $\ran B\perp\mul A^{**}$ is said to be an operator part of $A$ when $A=B \hplus (\{0\}\times \mul A)$, where ...

Property and Empire: The Law of Imperialism in Johnson v. M’Intosh [PDF]

open access: yes, 2007
Chief Justice\u27s Marshall\u27s opinion in Johnson v. M\u27Intosh, 21 U.S. (8 Wheat.)543 (1823) has long been a puzzle, both in its doctrinal structure and in long, strange dicta which are both triumphal and elegiac.

Roles Played by Critical Potentials in the Study of Poisson–Nernst–Planck Models with Steric Effects Under Relaxed Neutral Boundary Conditions

open access: yesAxioms
We examine the qualitative properties of ionic flows through membrane channels via Poisson–Nernst–Planck (PNP) type models with steric effects under relaxed electroneutrality boundary conditions, and more realistic setups in the study of ion channel ...

How to properly measure a current-voltage relation? - Interpolation versus ramp methods applied to studies of GABAA receptors

open access: yesFrontiers in Cellular Neuroscience, 2016
The relation between current and voltage, I-V relation, is central to functional analysis of membrane ion channels. A commonly used method, since the introduction of the voltage-clamp technique, to establish the I-V relation depends on the interpolation ...

Route Planning of a Polar Cruise Ship Based on the Experimental Prediction of Propulsion Performance in Ice

open access: yesJournal of Marine Science and Engineering, 2023
The effective assessment of risk and speed limitations in ice are critical for the route planning of polar cruise ships. While the Polar Operational Limit Assessment Risk Indexing System (POLARIS) is widely used to evaluate the operational risk in ice ...

Discovery and Targeted Proteomic Studies Reveal Striatal Markers Validated for Huntington's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Clinical trials for Huntington's disease (HD) enrolling persons before clinical motor diagnosis (CMD) lack validated biomarkers. This study aimed to conduct an unbiased discovery analysis and a targeted examination of proteomic biomarkers scrutinized by clinical validation. Methods Cerebrospinal fluid was obtained from PREDICT‐HD and

Cubic-like Features of I–V Relations via Classical Poisson–Nernst–Planck Systems Under Relaxed Electroneutrality Boundary Conditions

open access: yesAxioms
We focus on higher-order matched asymptotic expansions of a one-dimensional classical Poisson–Nernst–Planck system for ionic flow through membrane channels with two oppositely charged ion species under relaxed electroneutrality boundary conditions.

Archipriest Ioann Bazarov and V. A. Zhukovskij: an observation on the history of the religious-philosophical quest of the Russian educated society in the 1840ies [PDF]

open access: yesВестник Православного Свято-Тихоновского гуманитарного университета: Сериа III. Филология, 2013
Based upon an extensive range of unpublished correspondence between the poet V. A. Zhukovsk. and archipriest I. Bazarov, the article describes the poet’s religiousphilisophical quest, his longing for “live faith” as well as the constructions of the ...

Relation between the occurrence rate of ESF and the equatorial vertical plasma drift velocity at sunset derived from global observations [PDF]

open access: yesAnnales Geophysicae, 2008
In this study, we investigate two global climatological data sets; the occurrence rate of Equatorial Spread-F (ESF), associated with equatorial plasma irregularities, at ~400 km altitude obtained from CHAMP observations, and the evening equatorial ...

Direct Distances to Cepheids in the Large Magellanic Cloud: Evidence for a Universal Slope of the Period-Luminosity Relation up to Solar Abundance

open access: yes, 2005
We have applied the infrared surface brightness (ISB) technique to derive distances to 13 Cepheids in the LMC which span a period range from 3 to 42 days. From the absolute magnitudes of the variables calculated from these distances, we find that the LMC
