A locally finite model for gravity [PDF]

, 2008
Matter interacting classically with gravity in 3+1 dimensions usually gives rise to a continuum of degrees of freedom, so that, in any attempt to quantize the theory, ultraviolet divergences are nearly inevitable.

Magnetically Driven Biofabrication for Tissue Engineering: From Nanoparticle Design to Mag‐ATMP Translation

Advanced Healthcare Materials, EarlyView.
Magnetically responsive nanoparticles enable remote control over biomaterials, cells, and engineered tissues. This review summarizes material design, biological safety, fabrication and actuation strategies, computational validation, and translational pathways that support the development of magnetic tissue‐engineering platforms and future magnetically ...

Updated Interior Structure of Callisto From a Reanalysis of Galileo Data

Geophysical Research Letters
The internal structure of Callisto has been a long‐standing question since the Galileo mission. Previous analyses suggested a largely undifferentiated interior.

The average acceleration approach applied to gravity coefficients recovery based on GOCE orbits

Geodesy and Geodynamics, 2012
The average acceleration approach was applied to recover a gravity field model Model_ACA from GOCE precise science orbits from September 2 to November 2, 2010, and furthermore a so called sequential least square adjustment was used.

Comprehensive In Vitro Profiling Demonstrates Successful Immune Evasion of Bioengineered Immune‐Shielded Heart Valves

Advanced Healthcare Materials, EarlyView.
Living donor heart valves offer superior durability for pediatric patients but trigger immune rejection. Lentiviral delivery of viral immune‐evasion genes US2 and Serpin b9 into donor valve cells and valve tissue suppresses HLA expression, reduces PBMC clustering and cytotoxic killing, and induces transcriptional immune‐tolerance programs, paving the ...

DEEP-SEATED STRUCTURE OF THE LOWER AMUR PROVINCE AND EPITHERMAL GOLD MINERALIZATION THEREIN

Геодинамика и тектонофизика
The density and magnetic models of the Earth’s crust and lithospheric mantle were developed for the Lower Amur River gold-bearing area. Geological and geodynamical interpretations were made of the deep-seated inhomogeneities found there.

GOCE data evidence underplating beneath the Paraná basin

, 2012
The Paraná basin in the stable South American Platform accumulated a thick sediment layer during the Paleozoic, with more than 3500 m thickness. In Early Cretaceous the same area experienced a flood basalt volcanism which produced a LIP-(Large Igneous ...

The emergence of spacetime, or, quantum gravity on your desktop [PDF]

, 2008
Is there an approach to quantum gravity which is conceptually simple, relies on very few fundamental physical principles and ingredients, emphasizes geometric (as opposed to algebraic) properties, comes with a definite numerical approximation scheme, and

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...
