Singular limits for the bi-laplacian operator with exponential nonlinearity in $\R^4$ [PDF]

, 2007
Let $\Omega$ be a bounded smooth domain in $\mathbb{R}^{4}$ such that for some integer $d\geq1$ its $d$-th singular cohomology group with coefficients in some field is not zero, then problem {\Delta^{2}u-\rho^{4}k(x)e^{u}=0 & \hbox{in}\Omega, u ...

Caracterización morfológica y genética de las ectomicorrizas formadas entre Pinus montezumae y los hongos presentes en los bancos de esporas en la Faja Volcánica Transmexicana Morphologic and genetic characterization of ectomycorrhizae formed by Pinus montezumae and spore bank fungi in the Transmexican Volcanic Belt

Revista Mexicana de Biodiversidad, 2013
Los hongos ectomicorrízicos son indispensables para el establecimiento y funcionamiento de los bosques templados. Algunos de ellos tienen esporas u otros propágulos resistentes y longevos; éstos se acumulan en el suelo forestal formando bancos de ...

Asymptotically flat spacetimes in 3D bigravity

, 2012
We report that a class of three-dimensional bimetric theories contain asymptotically flat solutions. These spacetimes can be cast in a set of asymptotic conditions at null infinity which are preserved under the infinite dimensional BMS group.

Magnetic Field Effects on the Head Structure of Protostellar Jets [PDF]

, 1997
We present the results of 3-D SPMHD numerical simulations of supermagnetosonic, overdense, radiatively cooling jets. Two initial magnetic configurations are considered: (i) a helical and (ii) a longitudinal field.

What characterises well‐connected schools? Exploring centrality in inter‐organisational school networks

British Educational Research Journal, EarlyView.
Abstract Within the educational literature, inter‐organisational school networks are commonly considered instruments for administration, management, and school improvement, but are rarely scrutinised as objects of study themselves. Conversely, in organisational studies, this perspective is given more prominence.

Semiclassical stationary states for nonlinear Schr\"odinger equations under a strong external magnetic field [PDF]

, 2015
We construct solutions to the nonlinear magnetic Schr\"odinger equation $$ \left\{ \begin{aligned} - \varepsilon^2 \Delta_{A/\varepsilon^2} u + V u &= \lvert u\rvert^{p-2} u & &\text{in}\ \Omega,\\ u &= 0 & &\text{on}\ \partial\Omega, \end{aligned}

Gaussian Processes for Predictive QSAR Modeling of Chromatographic Processes

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Chromatography is a key unit operation in the biopharmaceutical manufacturing process used for protein purification and polishing. Design and optimization of these processes are resource‐intensive resulting from the complex combinatorial design space.
