SHA-1 and the Strict Avalanche Criterion [PDF]

open access: yesarXiv, 2016
The Strict Avalanche Criterion (SAC) is a measure of both confusion and diffusion, which are key properties of a cryptographic hash function. This work provides a working definition of the SAC, describes an experimental methodology that can be used to statistically evaluate whether a cryptographic hash meets the SAC, and uses this to investigate the ...

The Developing Chicken Yolk Sac Acquires Nutrient Transport Competence by an Orchestrated Differentiation Process of Its Endodermal Epithelial Cells*

open access: yesJournal of Biological Chemistry, 2012
Background: The heretofore unknown mechanism for acquisition of chick yolk sac function is described. Results: Receptor expression, lipoprotein secretion, and lipid droplet metabolism in endodermal epithelial cells (EECs) change drastically upon ...

MicroRNA‐371–373 cluster and methylome analysis suggests that a subset of ‘somatic‐type’ malignancies arising in germ cell tumors may originate in yolk sac tumor components

open access: yesThe Journal of Pathology, EarlyView.
Abstract Somatic‐type malignancies (SMs) arising in germ cell tumors (GCTs) are aggressive neoplasms resistant to systemic treatment. Most are diagnosed in metastatic sites after chemotherapy; however, they have also been well‐documented in primary testicular GCTs.

Microglial Drivers of Alzheimer's Disease Pathology: An Evolution of Diverse Participating States

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Microglia, the resident immune‐competent cells of the brain, become dysfunctional in Alzheimer's disease (AD), and their aberrant immune responses contribute to the accumulation of pathological proteins and neuronal injury. Genetic studies implicate microglia in the development of AD, prompting interest in developing immunomodulatory therapies

On the Approximability of the Yolk in the Spatial Model of Voting [PDF]

open access: yesarXiv
In the spatial model of voting, the yolk and LP (linear programming) yolk are important solution concepts for predicting outcomes for a committee of voters. McKelvey and Tovey showed that the LP yolk provides a lower bound approximation for the size of the yolk and there has been considerable debate on whether the LP yolk is a good approximation of the
