Quantum spin coherence in halogen-modified Cr7Ni molecular nanomagnets [PDF]

, 2014
Among the factors determining the quantum coherence of the spin in molecular magnets are the presence and the nature of nuclear spins in the molecule.

Phase transitions and symmetry energy in nuclear pasta [PDF]

, 2018
Cold and isospin-symmetric nuclear matter at sub-saturation densities is known to form the so-called pasta structures, which, in turn, are known to undergo peculiar phase transitions.

Cytological evaluation of thyroid lesions by nuclear morphology and nuclear morphometry

Journal of Cytology, 2017
Fine needle aspiration (FNA) of the thyroid gland is an effective diagnostic method. The Bethesda system for reporting thyroid cytopathology classifies them into six categories and gives implied risk for malignancy and management protocol in each category. Though the system gives specific criteria, diagnostic dilemma still exists.

Achieving the Way for Automated Segmentation of Nuclei in Cancer Tissue Images through Morphology-Based Approach: a Quantitative Evaluation [PDF]

, 2010
In this paper we address the problem of nuclear segmentation in cancer tissue images, that is critical for specific protein activity quantification and for cancer diagnosis and therapy.

Beyond Nuclear Pasta: Phase Transitions and Neutrino Opacity of Non-Traditional Pasta [PDF]

, 2014
In this work, we focus on different length scales within the dynamics of nucleons in conditions according to the neutron star crust, with a semiclassical molecular dynamics model, studying isospin symmetric matter at subsaturation densities.

The Nuclear Bulge of the Galaxy. III. Large-Scale Physical Characteristics of Stars and Interstellar Matter [PDF]

, 2002
We analyse IRAS and COBE DIRBE data at wavelengths between 2.2 and 240 mu of the central 500pc of the Galaxy and derive the large-scale distribution of stars and interstellar matter in the Nuclear Bulge.

Nuclear Morphology: When Round Kernels Do the Charleston [PDF]

Current Biology, 2006
New studies in Drosophila have identified a novel nuclear envelope protein with a farnesyl moiety, termed Kugelkern/Charleston, that helps regulate the size, shape and position of cellular blastoderm nuclei.

Using Hubble Space Telescope Imaging of Nuclear Dust Morphology to Rule Out Bars Fueling Seyfert Nuclei [PDF]

, 1999
If AGN are powered by the accretion of matter onto massive black holes, how does the gas in the host galaxy lose the required angular momentum to approach the black hole?

Luminosity-variation independent location of the circum-nuclear, hot dust in NGC 4151 [PDF]

, 2010
After recent sensitivity upgrades at the Keck Interferometer (KI), systematic interferometric 2um studies of the innermost dust in nearby Seyfert nuclei are within observational reach. Here, we present the analysis of new interferometric data of NGC 4151,
