Hierarchical axion inflation.

Physical review letters

Ben-Dayan I, Pedro FG, Westphal A.
PMID: 25615300
Phys Rev Lett. 2014 Dec 31;113(26):261301. doi: 10.1103/PhysRevLett.113.261301. Epub 2014 Dec 23.

We propose a new field theory mechanism for generating an effective trans-Planckian decay constant from sub-Planckian ones. Using the minimal two axions and a hierarchy between two axion decay constants is sufficient for realizing inflation through nonperturbative effects only...

Value of H(0) in the inhomogeneous universe.

Physical review letters

Ben-Dayan I, Durrer R, Marozzi G, Schwarz DJ.
PMID: 24949753
Phys Rev Lett. 2014 Jun 06;112(22):221301. doi: 10.1103/PhysRevLett.112.221301. Epub 2014 Jun 06.

Local measurements of the Hubble expansion rate are affected by structures like galaxy clusters or voids. Here we present a fully relativistic treatment of this effect, studying how clustering modifies the mean distance- (modulus-)redshift relation and its dispersion in...

Psammomys obesus, a particularly important animal model for the study of the human diabetic nephropathy.

Anatomy & cell biology

Scherzer P, Katalan S, Got G, Pizov G, Londono I, Gal-Moscovici A, Popovtzer MM, Ziv E, Bendayan M.

The Psammomys obesus lives in natural desert habitat on low energy (LE) diet, however when maintained in laboratory conditions with high energy (HE) diet it exhibits pathological metabolic changes resembling those of type 2 diabetes. We have evaluated and...

Decline in Memory, Visuospatial Ability, and Crystalized Cognitive Abilities in Older Adults: Normative Aging or Terminal Decline?.

Journal of aging research

Thymoma-associated multiorgan autoimmunity disease can be seen in patients with thymomas and presents with features of graft versus host disease. Here, we report a case of a 52-year-old woman with a complex medical history including malignant thymoma, myasthenia gravis,...

Validation and Optimization of Proximal Femurs Microstructure Analysis Using High Field and Ultra-High Field MRI.

Diagnostics (Basel, Switzerland)

PMID: 34573945
Diagnostics (Basel). 2021 Sep 02;11(9). doi: 10.3390/diagnostics11091603.

Trabecular bone could be assessed non-invasively using MRI. However, MRI does not yet provide resolutions lower than trabecular thickness and a comparative analysis between different MRI sequences at different field strengths and X-ray microtomography (μCT) is still missing. In...

Impaired aerobic capacity and premature fatigue preceding muscle weakness in the skeletal muscle Tfam-knockout mouse model.

Disease models & mechanisms
