Triggering Star Formation by Galaxy-Galaxy Interactions [PDF]

open access: yesSymposium - International Astronomical Union, 2004
We analyzed the effects of having a close companion on the star formation activity of galaxies in the 8K galaxy pair catalog selected from the 2dFGRS. We found that, statistically, galaxies with rp < 25h−1 kpc and ΔV < 100km s−1 have enhanced star formation with respect to isolated galaxies with the same luminosity and redshift distribution.

Triazine‐Trione Thermosets with High Processability for Scaffold Applications in Bone Tissue Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
Novel photo‐clickable triazine‐trione thermosets can be shaped and cured under mild conditions, including room and physiological temperatures. These materials are biocompatible and support osteogenic differentiation of bone marrow–derived mesenchymal stem cells on their surface.

Hierarchical galaxy formation [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2002
We describe the GALFORM semi-analytic model for calculating the formation and evolution of galaxies in hierarchical models. It improves upon, and extends, the Cole et al 1994 model. The model employs a new Monte-Carlo algorithm to follow the merging evolution of dark matter halos with arbitrary mass resolution. It incorporates realistic descriptions of

Star Formation for Predictive Primordial Galaxy Formation

open access: yes, 2015
The elegance of inflationary cosmology and cosmological perturbation theory ends with the formation of the first stars and galaxies, the initial sources of light that launched the phenomenologically rich process of cosmic reionization. Here we review the

Facile Bottom‐Up Assembly of Photonic Micropatterns via Surface‐Guided Colloidal Crystallization

open access: yesAdvanced Materials, EarlyView.
High‐resolution photonic micropatterns with vivid structural colors are fabricated through bottom‐up assembly, guided by surface‐dependent regioselective heterogeneous nucleation and crystal growth of colloidal particles. Full‐spectrum color tunability is achieved by controlling particle size and interparticle attraction, while in situ color mixing is ...

Roles of Supernova and Active Galactic Nucleus Feedback in Shaping the Baryonic Content in a Wide Range of Dark Matter Halo Masses

open access: yesThe Astrophysical Journal Supplement Series
We build upon FEGA25 , a previously introduced semianalytic model (SAM) for galaxy formation and evolution, by focusing on its enhanced treatment of supernova (SN) and active galactic nucleus (AGN) feedback mechanisms.

O and Fe abundance correlations and distributions inferred for the thick and thin disk [PDF]

open access: yesSerbian Astronomical Journal, 2015
A linear [Fe/H]-[O/H] relation is found for different stellar populations in the Galaxy (halo, thick disk, thin disk) from a data sample obtained in a recent investigation (Ramґırez et al. 2013).

End‐to‐End Sensing Systems for Breast Cancer: From Wearables for Early Detection to Lab‐Based Diagnosis Chips

open access: yesAdvanced Materials Technologies, EarlyView.
This review explores advances in wearable and lab‐on‐chip technologies for breast cancer detection. Covering tactile, thermal, ultrasound, microwave, electrical impedance tomography, electrochemical, microelectromechanical, and optical systems, it highlights innovations in flexible electronics, nanomaterials, and machine learning.

Versatile Gasochromic Hydrogen Detection via Supraparticle‐Based Applied Composite Materials

open access: yesAdvanced Optical Materials, EarlyView.
Silica‐platinum‐resazurin supraparticles are embedded into PMMA to form suprabeads and thin films. The thereby obtained indicators change color from purple to pink to colorless on hydrogen exposure. The indicator systems are tested under various environmental conditions, and their performance is related to their microscopically visualized structure ...

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

open access: yesAdvanced 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.
