Hierarchical Cycle Accounting: A New Method for Application Performance Tuning

To address the growing difficulty of performance debugging on modern processors with increasingly complex micro-architectures, we present Hierarchical Cycle Accounting (HCA), a structured, hierarchical, architecture-agnostic methodology for the identificat ...

Dynamics of heterogeneity in urban networks: aggregated traffic modeling and hierarchical control

Nikolaos Geroliminis, Mohsen Ramezani Ghalenoei, Jack Haddad

Real traffic data and simulation analysis reveal that for some urban networks a well-defined Macroscopic Fundamental Diagram (MFD) exists, which provides a unimodal and low-scatter relationship between the network vehicle density and outflow. Recent studie ...

CDK6 Levels Regulate Quiescence Exit in Human Hematopoietic Stem Cells

Jie Chen, Cyrille Dunant

Regulated blood production is achieved through the hierarchical organization of dormant hematopoietic stem cell (HSC) subsets that differ in self-renewal potential and division frequency, with long-term (LT)-HSCs dividing the least. The molecular mechanism ...

HOXA5 Counteracts Stem Cell Traits by Inhibiting Wnt Signaling in Colorectal Cancer

Paloma Ordonez Moran, Caroline Dafflon

Hierarchical organization of tissues relies on stem cells, which either self-renew or produce committed progenitors predestined for lineage differentiation. Here we identify HOXA5 as an important repressor of intestinal stem cell fate in vivo and identify ...

Emergent Power Hierarchies and Group Performance

Daniel Gatica-Perez, Denise Frauendorfer, Dairazalia Sanchez Cortes

In newly formed groups, informal hierarchies emerge automatically and readily. In this study, we argue that emergent group hierarchies enhance group performance (Hypothesis 1) and we assume that the more the power hierarchy within a group corresponds to th ...

A Hierarchical Structure of Cortical Interneuron Electrical Diversity Revealed by Automated Statistical Analysis

Henry Markram, Sean Lewis Hill, Idan Segev

Although the diversity of cortical interneuron electrical properties is well recognized, the number of distinct electrical types (e-types) is still a matter of debate. Recently, descriptions of interneuron variability were standardized by multiple laborato ...
