Quasar-galaxy and AGN-galaxy cross-correlations [PDF]

, 1998
We compute quasar-galaxy and AGN-galaxy cross-correlation functions for samples taken from the \cite{VCV98} catalog of quasars and active galaxies, using tracer galaxies taken from the Edinburgh/Durham Southern Catalog.

Synergistic Microcrack Engineering and Auxetic Metamaterials for Enhanced Sensitivity in Stretchable Strain Sensors

Advanced Materials Technologies, EarlyView.
A highly sensitive crack‐based piezoresistive strain sensor is developed using a biaxially pre‐stretched multi‐walled carbon nanotubes/Ecoflex composite and integrated with auxetic metamaterials. Biaxial pre‐stretching improves the sensitivity by 56% compared to the uniaxially pre‐stretched strain sensor.

The κ-Model under the Test of the SPARC Database

Universe
Our main goal here is to conduct a comparative analysis between the well-known MOND theory and a more recent model called the κ-model. An additional connection, between the κ-model and two other novel MOND-type theories, Newtonian Fractional-Dimension ...

On the Root Cause of the Host “Mass Step” in the Hubble Residuals of Type Ia Supernovae

The Astrophysical Journal, 2023
It is well established that the Hubble residuals of Type Ia supernovae (SNe Ia) show the luminosity step with respect to their host galaxy stellar masses.

Towards an understanding of third-order galaxy-galaxy lensing

, 2012
Third-order galaxy-galaxy lensing (G3L) is a next generation galaxy-galaxy lensing technique that either measures the excess shear about lens pairs or the excess shear-shear correlations about lenses.

The 2dF Galaxy Redshift Survey: spectra and redshifts [PDF]

, 2001
The 2dF Galaxy Redshift Survey (2dFGRS) is designed to measure redshifts for approximately 250 000 galaxies. This paper describes the survey design, the spectroscopic observations, the redshift measurements and the survey data base.

Controlled Air Gap Formation between W and TiO2 Films via Sub‐Surface TiO2 Atomic Layer Etching

Advanced Materials Technologies, EarlyView.
Delivering SiH4 and WF6 to a lined array of TiO2 films produces a thin film of tungsten while simultaneously, the underlying TiO2 is removed. When the W‐coated TiO2 structure is exposed to further etching cycles after deposition, TiO2 etching continues vertically and laterally, creating a self‐supported W structure and a vacant air gap.

Baryon Acoustic Oscillations in the Sloan Digital Sky Survey Data Release 7 Galaxy Sample [PDF]

, 2009
The spectroscopic Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) galaxy sample represents the final set of galaxies observed using the original SDSS target selection criteria. We analyse the clustering of galaxies within this sample, including both

A Proof‐of‐Concept Assessment of a Novel Wearable Eyelid Muscle Device: A Pre‐Clinical Animal Cadaver Study for Eyelid Closure Restoration

Advanced Robotics Research, EarlyView.
This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.
