The necessity of dark matter in MOND within galactic scales [PDF]

, 2008
To further test MOdified Newtonian Dynamics (MOND) on galactic scales -- originally proposed to explain the rotation curves of disk galaxies without dark matter -- we study a sample of six strong gravitational lensing early-type galaxies from the CASTLES

Intuition–Driven Prospection and Uncertainty Misalignment: Sources of Entrepreneurial Agency Problems in Ventures

Strategic Change, EarlyView.
ABSTRACT Start‐up CEOs are usually more aligned with the interests of the venture board compared to CEOs in legacy firms, and therefore it is usual to conclude that the traditional agency problem is lower in ventures. In this article, it is argued that this is only half of the story, and that the agency problem is reversed in early ventures such that ...

A New Framework for Understanding Systematic Errors in Cluster Lens Modeling. IV. Constraints from the Giant Arc in Abell 370

The Astrophysical Journal
We aim to improve cluster lens modeling and source reconstruction by utilizing the full information in giant, caustic-crossing arcs lensed by galaxy clusters.

Mass discrepancy in galaxy clusters as a result of the offset between dark matter and baryon distributions

, 2010
Recent studies of lensing clusters reveal that it might be fairly common for a galaxy cluster that the X-ray center has an obvious offset from its gravitational center which is measured by strong lensing. We argue that if these offsets exist, then X-rays

Pulsed Laser Ablation in Liquid: Numerical Evaluation of Laser Fluence

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
Pulsed laser ablation in liquid is a very powerful technique that allows to synthesize colloidal solution of nanoparticles (NPs) without waste. Herein, a computational approach that given the experimental parameters and draws the laser ray paths inside the experimental apparatus is developed, the effective fluence on the target surface is evaluated ...

Precision Measurement of Large Shear Signals

The Astrophysical Journal Letters
So far, estimators of galaxy shape distortions are only carefully studied perturbatively in the case of small shear signals, mainly for weak-lensing science.

Friction Shock Absorbers and Reverse Thrust for Fast Multirotor Landing on High‐Speed Vehicles

Journal of Field Robotics, EarlyView.
ABSTRACT Typical landing gears of small uninhabited aerial vehicles (UAV) limit their capability to land on vehicles moving at more than 20–50 km/h due to high drag forces, high pitch angles and potentially high relative horizontal velocities. To enable landing at higher speeds, a combination of lightweight friction shock absorbers and reverse thrust ...
