Functions of linear operators: Parameter differentiation [PDF]

open access: yes, 1999
We derive a useful expression for the matrix elements $[\frac{\partial f[A(t)]}{\partial t}]_{i j}$ of the derivative of a function $f[A(t)]$ of a diagonalizable linear operator $A(t)$ with respect to the parameter $t$. The function $f[A(t)]$ is supposed to be an operator acting on the same space as the operator $A(t)$.

Reactions of 1,4‐Diborinine Derivatives with CO2

open access: yesChemPhysChem, EarlyView.
The reaction of CO2 with seven molecules featuring a 1,4‐diborinine central ring is studied by means of density functional theory calculations. The selected systems present five‐ and six‐membered aza rings surrounding 1,4‐diborinine. The computed reactivity trends and origin of regioselectivity are quantitatively analyzed with the activation strain ...

El derecho a la ciudad: de Henri Lefebvre a los análisis sobre la ciudad capitalista contemporánea

open access: yes, 2016
The right to the city, defined by Henri Lefebvre in 1967 as the right of urban inhabitants to build, decide and create the city, and make of it a privileged space of anti-capitalist struggle, is again at the center of political debate. Social scientists,

Using the HClO4–H2O2 System for Efficient Platinum Leaching: Optimal Conditions and Kinetics

open access: yesChemPlusChem, EarlyView.
GA: The platinum leaching using HClO4 and H2O2 is studied. For each HClO4 concentration, an H2O2/HClO4 = 2.5 ratio optimizes the kinetics. The best operating conditions are ≈70 °C, [HClO4] 3 m, and [H2O2] 7.2 m. The leaching process is governed by diffusion in the boundary layer and chemical reaction. In this new extraction process, Cl2(g) is generated

Acid-sensing ion channels 1a (ASIC1a) inhibit neuromuscular transmission in female mice [PDF]

open access: yes, 2014
Acid-sensing ion channels (ASIC) open in response to extracellular acidosis. ASIC1a, a particular subtype of these channels, has been described to have a postsynaptic distribution in the brain, being involved not only in ischemia and epilepsy, but also ...
