SELF-CALIBRATION OF GRAVITATIONAL SHEAR-GALAXY INTRINSIC ELLIPTICITY CORRELATION IN WEAK LENSING SURVEYS

, 2010
The galaxy intrinsic alignment is a severe challenge to precision cosmic shear measurement. We propose self-calibrating the induced gravitational shear-galaxy intrinsic ellipticity correlation (the GI correlation) in weak lensing surveys with photometric

Engineering an artificial trachea: Quantitative benchmarks and modular strategies for mechanics, epithelialization, and vascular integration

FlexMat, EarlyView.
In this work, we first examine the limitations of surgical repair and stenting, including migration, granulation, mucus plugging, and infection. We then translate these failures into engineering constraints involving geometry, mechanics, fixation, degradation, junctional stress, and remodeling.

Weak lensing: applications in gravitational wave and galaxy cluster cosmology [PDF]

Radiation travelling through the Universe is weakly lensed by Large Scale Structure. Measurements of this effect are a valuable probe of the content and dynamics of the Universe.

Applying a Complexity Lens to Policy Implementation: How Feedback Loops Help to Understand Systems Change in Integrated Healthcare

The International Journal of Health Planning and Management, EarlyView.
ABSTRACT Background Although a complexity theory lens can help to understand national policy implementation at a local government level, application of this lens often remains at a metaphorical level. We illustrate how complexity concepts, such as adaptation, feedback, emergence and co‐evolution can be used practically in research on policy ...

Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

WEAK GRAVITATIONAL LENSING BY STOCHASTIC GRAVITATIONAL WAVE BACKGROUND [PDF]

Publications of The Korean Astronomical Society, 2007
On the formulation frameworks of linearly perturbed spacetime and weak gravitational lensing(WGL) we studied the statistical properties of a bundle of light rays propagating through stochastic gravitational wave background(SGWB). For this we considered the SGWB as tensor perturbations of linearly perturbed Friedmann spacetime.

The Shear TEsting Programme 1: Weak lensing analysis of simulated ground-based observations [PDF]

The Shear TEsting Programme, STEP, is a collaborative project to improve the accuracy and reliability of all weak lensing measurements in preparation for the next generation of wide-field surveys.

Cosmic tomography with weak gravitational lensing [PDF]

, 2023
We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

Developing and Testing a Citywide Inclusive Sanitation Financial Tool

Sustainable Development, EarlyView.
ABSTRACT Citywide Inclusive Sanitation (CWIS) represents a paradigm shift in the provision of safely managed sanitation services with a framework of three outcomes—equity, safety and sustainability. There are several sanitation financial tools, but none of these fully address all CWIS outcomes. Citywide Inclusive Sanitation Financial Tool (CWIS‐FiT) is
