Calculable membrane theory [PDF]

open access: yesarXiv, 2009
The key to membrane theory is to enlarge the diffeomorphism group until 4D gravity becomes almost topological. Just one ghost survives and its central charges can cancel against matter. A simple bosonic membrane emerges, but its flat D = 28 target space is unstable.

CRC 1114 - Report Membrane Deformation by N-BAR Proteins: Extraction of membrane geometry and protein diffusion characteristics from MD simulations [PDF]

open access: yesarXiv, 2017
We describe simulations of Proteins and artificial pseudo-molecules interacting and shaping lipid bilayer membranes. We extract protein diffusion Parameters, membrane deformation profiles and the elastic properties of the used membrane models in preparation of calculations based on a large scale continuum model.

Case studies on the genes zerknuellt, decapentaplegic and short gastrulation in the beetle Tribolium illustrate concepts in evolutionary developmental biology [PDF]

open access: yes, 2006
Evolutionary developmental biology (Evo-Devo) attempts to trace modifications in development that have lead to evolutionary novelty. Some important concepts in Evo-Devo are GENE DUPLICATION, SUBFUNCTIONALIZATION, MODULARITY, CO-OPTION, CIS-REGULATORY ...

Developmental Potential of Mouse Embryos without Extraembryonic Membranes in Modified Organ Culture [PDF]

open access: yes, 2004
The long term stationary culture of postimplanatation embryos without extraembryonic membranes is a method to assess their developmental potential in vitro.

Desarrollo embrionario de Columba livia(Aves: Columbiformes) desde una perspectiva altricial-precoz Desenvolvimento embrionário de Columba livia(Aves: Columbiformes) a partir de uma perspectiva altricial-precoce Embryonic development of Columba livia(Aves: Columbiformes) from an altricial-precocial perspective

open access: yesRevista Colombiana de Ciencias Pecuarias, 2012
Objetivo: en el presente trabajo se caracteriza la morfogénesis de Columba livia y se propone una tabla con 43 estadios embrionarios. La ontogenia de dicha especie fue dividida en tres etapas: temprana, media y tardía.

X-chromosome inactivation mosaicism in the three germ layers and the germ line of the mouse embryo [PDF]

open access: yes, 1982
Electrophoretic variant forms of the X-linked enzyme phosphoglycerate kinase (PGK-1, E.C.2, 7, 2, 3) have been used to examine X-chromosome mosaicism in tissues from 121/2-day post coitum heterozygous female mouse embryos.

Influence of Membrane Characteristics on Efficiency of Vacuum Membrane Distillation: a Lattice Boltzmann Study [PDF]

open access: yesarXiv
With increasing water scarcity, membrane distillation technology has gained widespread attention as an innovative method for seawater desalination.However,existing studies often overlook the influence of membrane characteristics on mass transfer efficiency.

Polydactylous limbs in Strong's Luxoid mice result from ectopic polarizing activity [PDF]

open access: yes, 1995
Strong's Luxoid (1st^D) is a semidominant mouse mutation in which heterozygotes show preaxial hindlimb polydactyly, and homozygotes show fore- and hindlimb polydactyly.
