Computer vision enables taxon-specific identification of African carnivore tooth marks on bone

open access: yesScientific Reports
Taphonomic works aim at discovering how paleontological and archaeofaunal assemblages were formed. They also aim at determining how hominin fossils were preserved or destroyed.

Discrete Loewner evolution [PDF]

open access: yesarXiv, 2003
We study a one parameter family of discrete Loewner evolutions driven by a random walk on the real line. We show that it converges to the stochastic Loewner evolution (SLE) under rescaling. We show that the discrete Loewner evolution satisfies Markovian-type and symmetry properties analogous to SLE, and establish a phase transition property for the ...

Intratumor heterogeneity and branched evolution revealed by multiregion sequencing.

open access: yesNew England Journal of Medicine, 2012
BACKGROUND Intratumor heterogeneity may foster tumor evolution and adaptation and hinder personalized-medicine strategies that depend on results from single tumor-biopsy samples.

Elmer\u27s Evolution [PDF]

open access: yes, 2014
Spring is here! Can\u27t you hear the rumble of skates as the children zip by the house in their youthful glee? Can\u27t you hear the mingled chatter of the spring birds?

STAT3 expression is reduced in cardiac pericytes in HFpEF and its loss reduces cellular adhesion and induces pericyte senescence

open access: yesFEBS Letters, EarlyView.
Heart failure with preserved ejection fraction (HFpEF) accounts for half of the heart failure cases. It is characterised by microvascular dysfunction, associated with reduced pericyte coverage and diminished STAT3 expression in pericytes. Loss of STAT3 impairs pericyte adhesion, promotes senescence, and activates a pro‐fibrotic gene program.

Systematic errors in orthology inference and their effects on evolutionary analyses

open access: yesiScience, 2021
Summary: The availability of complete sets of genes from many organisms makes it possible to identify genes unique to (or lost from) certain clades. This information is used to reconstruct phylogenetic trees; identify genes involved in the evolution of ...

Group classification of the general evolution equation: local and quasi-local symmetries [PDF]

open access: yesSIGMA 1 (2005), 009, 7 pages, 2005
We expand our group classification of quasilinear evolution equations (Acta Appl.Math., v.69, 2001) to the case of general evolution equation in one spatial variable. This enables obtaining several new classes of evolution equations with nontrivial Lie symmetry.

Creationism and evolution [PDF]

open access: yes, 2009
In Tower of Babel, Robert Pennock wrote that “defenders of evolution would help their case immeasurably if they would reassure their audience that morality, purpose, and meaning are not lost by accepting the truth of evolution.” We first consider the ...

Simulating Galaxy Evolution

open access: yes, 1998
The forwards approach to galaxy formation and evolution is extremely powerful but leaves several questions unanswered. Foremost among these is the origin of disks.

Cytoplasmic delivery of antibodies through grafting a functional single complementarity‐determining region loop

open access: yesFEBS Letters, EarlyView.
We achieved cytoplasmic delivery of non‐cell‐penetrating IgGs by grafting a single functional complementarity‐determining region 1 (CDR1) from the light chain variable region (VL) of the cell‐internalizable 3D8 antibody. The engineered IgG acquired cell‐penetrating ability while maintaining antigen affinity, highlighting CDR1 grafting as a promising ...
