The role of crystallographic orientation of martensitic variants on cleavage crack propagation [PDF]
arXiv, 2016 Cleavage crack propagation has been investigated in a low-carbon lath-martensitic steel using electron back-scattered diffraction technique. The ability of different martensitic boundaries within prior-austenite grain, such as sub-block, block and packet boundaries to resist cleavage crack propagation has been estimated in terms of Kurdjumov-Sachs ...

Social progress at the expense of economic equality? New data on left parties' equality preferences
European Journal of Political Research, EarlyView.Abstract Have concerns about equal rights and equal chances crowded out economic equality as a priority of left parties? Despite the increased importance of inequality in political science, this contentiously fought debate has been standing on shaky empirical foundations.

Reverse Engineering of Proteasomal Translocation Rates [PDF]
arXiv, 2008 We address the problem of proteasomal protein translocation and introduce a new stochastic model of the proteasomal digestion (cleavage) of proteins. In this model we account for the protein translocation and the positioning of cleavage sites of a proteasome from first principles.

Computational Synthesis of Substrates by Crystal Cleavage [PDF]
arXiv, 2020 The discovery of novel substrate materials has been dominated by trial and error, opening the opportunity for a systematic search. To identify stable crystal surfaces, we generate bonding networks for materials from the Materials Project database with one to five atoms in the primitive unit cell.

Aging Cell, EarlyView.Amyloid‐β (Aβ) oligomers affect VDAC1 electrophysiology and the physiological metabolic cross‐talk between cytosol and mitochondria. The use of a small, synthetic VDAC1‐antagonist peptide, derived from hexokinase, restores mitochondrial functionality, and respiration in cellular models of Alzheimer's disease. ABSTRACT Mitochondrial dysfunction has been

An atomistic-to-continuum analysis of crystal cleavage in a two-dimensional model problem [PDF]
arXiv, 2011 A two-dimensional atomic mass spring system is investigated for critical fracture loads and its crack path geometry. We rigorously prove that, in the discrete-to-continuum limit, the minimal energy of a crystal under uniaxial tension leads to a universal cleavage law and energy minimizers are either homogeneous elastic deformations or configurations ...

From Cosmic Explosions to Terrestrial Fires?: A Reply [PDF]
arXiv, 2020 Deschamps and Mottez (hereafter DM) argue that the Gauss-Matuyama terrestrial magnetic field reversal may have left a vanishing main dipole moment to the field for a time of order 10,000 years. They say this may have allowed an enhanced cosmic ray flux, boosting the effect we proposed in Melott and Thomas (2019).

Geology of symmetric grounds [PDF]
arXiv, 2019 Let us say that a model of $\mathsf{ZF}$ is a symmetric ground if $V$ is a symmetric extension of the model. In this paper, we investigate set-theoretic geology of symmetric grounds. Under a certain assumption, we show that all symmetric grounds of $V$ are uniformly definable. We also show that if $\mathsf{AC}$ is forceable over $V$, then the symmetric

Can pseudocomplementary peptide nucleic acid nucleases (pcPNANs) be a new tool for genetic engineering? [PDF]
arXiv, 2014 Zinc-finger nucleases (ZFNs) and transcription activator-like effector nucleases (TALENs) comprise a powerful class of tools that are redefining the boundaries of biological research. Although these technologies have begun to enable targeted genome modifications, there remains a need for new technologies that are affordable, scalable, and easy to ...

Martini coarse-grained model for clay-polymer nanocomposites [PDF]
arXiv, 2019 We have developed a coarse-grained (CG) model of a polymer-clay system consisting of organically modified montmorillonite nanoclay as the nanoparticle in accordance with the MARTINI forcefield. We have used mechanical properties and cleavage free energy of clay particle to respectively parameterize bonded and nonbonded interaction parameters for an ...
