Hiding its age: the case for a younger bulge

open access: yes, 2016
The determination of the age of the bulge has led to two contradictory results. On the one side, the color-magnitude diagrams in different bulge fields seem to indicate a uniformly old ($>$10 Gyr) population.

Kinematics of extragalactic bulges: evidence that some bulges are really disks [PDF]

open access: yesSymposium - International Astronomical Union, 1993
Recent work on the dynamics of galaxy bulges has been dominated by two themes. (1) Bulges share the richness in kinematic structure that is currently being discovered in elliptical galaxies. This includes kinematic evidence for triaxiality and for accretion (counterrotating gas and stellar components).

Fully Printed Organic Electrochemical Transistors With Low‐Resistance Electrodes on Planarized 3D‐Printed Substrates

open access: yesAdvanced Materials Technologies, EarlyView.
This paper explores integrating organic electrochemical transistors (OECTs) with planarized 3D‐printed substrates, utilizing ironing to enhance surface suitability for printing, dispense printing for thick, low‐resistance silver electrodes, and inkjet printing for semiconductor deposition.

The GIRAFFE Inner Bulge Survey (GIBS). I. Survey Description and a kinematical map of the Milky Way bulge

open access: yes, 2014
The Galactic bulge is a massive, old component of the Milky Way. It is known to host a bar, and it has recently been demonstrated to have a pronounced boxy/peanut structure in its outer region.

Electrolyte‐Jet 3D Printing of Copper‐Based Strain Sensors for Physiological Signal Monitoring and Robotic Manipulation

open access: yesAdvanced Materials Technologies, EarlyView.
Electrolyte‐jet (EJ) 3D printing turns copper ions into precisely arranged copper microspheres, which combine with flexible polymers and carbon nanomaterials to create durable, high‐sensitivity sensors. These sensors accurately monitor human motion and physiological signals. Real‐time robotic hand control via gesture mirroring demonstrates an intuitive

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Spin-up of low mass classical bulges in barred galaxies

open access: yes, 2011
Secular evolution is one of the key routes through which galaxies evolve along the Hubble sequence. Not only the disk undergoes morphological and kinematic changes, but also a preexisting classical bulge may be dynamically changed by the secular ...

Identification of PKN2 and MOB4 as Coordinators of Collective Cell Migration

open access: yesAdvanced Science, EarlyView.
Through a genetic screen, PKN2 and MOB4 are identified as two proteins regulating the healing of an epithelial model wound. PKN2 promotes collective cell migration by maintaining the cohesion of cell monolayers from their lateral junctions, whereas MOB4 restrains collective cell migration and provides a lamellipodial cue for front‐rear polarity in ...
