The Large-scale Structure of the Universe: Probes of Cosmology and Structure Formation [PDF]

, 2013
The usefulness of large-scale structure as a probe of cosmology and structure formation is increasing as large deep surveys in multi-wavelength bands are becoming possible.

Accurate N-body simulations with local primordial non-Gaussianities: Initial conditions and aliasing

Astronomy & Astrophysics
The new generation of galaxy surveys designed to constrain local primordial non-Gaussianity (PNG) requires N-body simulations that accurately reproduce its effects.

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

Molecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

Galaxy clustering and galaxy clusters from the UKIDSS DXS [PDF]

, 2011
Recent wide and deep surveys allow us to investigate the large scale structure of the Universe at high redshift. We present studies of the clustering of high redshift galaxies and galaxy clusters, using reprocessed UKIDSS DXS catalogues.

Exploring the Signature of Assembly Bias and Modified Gravity Using Small-scale Clusterings of Galaxies

The Astrophysical Journal
We apply a halo velocity bias model, γ _f , within the Aemulus simulation suite for General Relativity to investigate its efficacy in identifying the signature of assembly bias and Modified Gravity (MG).

Tracing the high-z cosmic web with Quaia: Catalogues of voids and clusters in the quasar distribution

Astronomy & Astrophysics
Context. Understanding the formation and evolution of the cosmic web of galaxies is a fundamental goal of both theoretical and observational cosmology, which use various tracers of the cosmic large-scale structure at an ever wider range of redshifts ...

p190A/ARHGAP35 and p190B/ARHGAP5 proteins in endometrial cancer: a novel cancer‐relevant paralog interplay

Molecular Oncology, EarlyView.
This study identifies ARHGAP5, in addition to the frequently mutated ARHGAP35, as significantly mutated in endometrial cancer. Mutations in both genes co‐occur and are associated with their correlated downregulation. Functional CRISPR studies show that both paralogs regulate similar pathways, including actin cytoskeleton organization.

Development of large-scale structure in the Universe

, 1991
This volume grew out of the 1988 Fermi lectures given by Professor Ostriker, and is concerned with cosmological models that take into account the large scale structure of the universe. He starts with homogeneous isotropic models of the universe and then,

Testing the cosmological principle with quasars

Astronomy & Astrophysics
The cosmological principle posits that the universe is homogeneous and isotropic on the large scales. In history, the cosmological principle was confirmed by various cosmological observations from CMB to large scale structure.

Automated FRAP microscopy for high‐throughput analysis of protein dynamics in chromatin organization and transcription

FEBS Open Bio, EarlyView.
RoboMic is an automated confocal microscopy pipeline for high‐throughput functional imaging in living cells. Demonstrated with fluorescence recovery after photobleaching (FRAP), it integrates AI‐driven nuclear segmentation, ROI selection, bleaching, and analysis.
