One of neuroscience’s greatest challenges is to bridge the gaps between the external environment, the brain’s internal electrical activity, and the abstract workings of behavior and cognition. Many ne...
The role of metabolism (and the microbiome) in defining the clinical efficacy of dietary flavonoids
absorption ADME flavonoids genotype health metabolism microbiome
2018/11/12
At a population level, there is growing evidence of the beneficial effects of dietary flavonoids on health. However, there is extensive heterogeneity in the response to increased intake, which is like...
Challenges in defining the role of dietary protein in bone health
Challenges bone health dietary protein
2018/11/14
The systematic review of dietary protein and bone health and falls in the current issue of the Journal by Shams-White et al. (1) is thorough and timely. Their key findings are that dietary protein int...

The individuation of areas that are more likely to be affected by new events in volcanic regions is of fundamental relevance for the mitigation of the possible consequences, both in terms of loss of h...
Reading through this issue of Oceanography, it will become apparent that researchers in different disciplines see their seamounts in quite different ways. The term seamount has been defined many times...
Twist1 and Etv5 are part of a transcription factor network defining T helper cell identity

CD4 T helper cells control immunity to pathogens and the development of inflammatory disease by acquiring the ability to secrete effector cytokines. Cytokine responsiveness is a critical component of ...
Defining the mechanism of prostaglandin E₂-enhanced hematopoietic stem and progenitor cell homing
Prostaglandin Homing HIF1-alpha
2015/5/21
Hematopoietic stem cell (HSC) transplantation is a lifesaving therapy for a number of hematological disorders. However, to be effective, transplanted HSCs must efficiently “home” to supportive niches ...
A universal first order formula defining the ring of integers in a number field
universal first order formula defining ring integers number field
2012/3/1
We show that the complement of the ring of integers in a number field K is Diophantine. This means the set of ring of integers in K can be written as {t in K | for all x_1, ..., x_N in K, f(t,x_1, ......
Remarks on modular representations of finite groups of Lie type in non-defining characteristic
Finite groups of Lie type unipotent representations decomposition numbers
2011/8/23
Abstract: Let $G$ be a finite group of Lie type and $\ell$ be a prime which is not equal to the defining characteristic of $G$. In this note we discuss some open problems concerning the $\ell$-modular...
A note on dynamical systems defining Jacobi's theta-constants
Jacobi’s theta-constants modular forms Poisson structures
2010/12/28
We propose a system of ordinary differential equations which defines Jacobi’s theta-constant series. The relations of this system to the classical Darboux–Halphen equations and equations introduced by...

We propose a system of ordinary differential equations which defines Jacobi’s theta-constant series. The relations of this system to the classical Darboux–Halphen equations and equations introduced by...
Defining and Computing Topological Persistence for 1-cocycles
Topological Persistence 1-cocycles
2011/2/22
The concept of topological persistence, introduced recently in computational topology, finds applications in studying a map in relation to the topology of its domain. Since its introduction, it has be...
Defining Z in Q
Defining Z in Q math
2010/11/22
We show that ${\mathbb Z}$ is definable in ${\mathbb Q}$ by a universal first-order formula in the language of rings. We also present an $\forall\exists$-formula for ${\mathbb Z}$ in ${\mathbb Q}$ wi...
Inductive McKay Condition in defining Characteristic
Inductive McKay Condition defining Characteristic
2010/11/29
We reformulate the inductive McKay condition, from Isaacs–Malle–Navarro [IMN07], and apply the new criterion to simple groups of Lie type, when the prime is the defining characteristic p. Thereby we m...
Improving risk assessment by defining consistent and reliable system scenarios

2009/12/16
During the entire procedure of risk assessment for hydrologic hazards, the selection of consistent and reliable scenarios, constructed in a strictly systematic way, is fundamental for the quality and ...
