The construction of colorimetry by committee [PDF]

open access: yes, 1996
This paper explores the confrontation of physical and contextual factors involved in the emergence of the subject of color measurement, which stabilized in essentially its present form during the interwar period. The contentions surrounding the specialty

The Slow‐Rotating Nucleus of Comet C/2013 R1 (Lovejoy)

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The close approach of comet C/2013 R1 (Lovejoy) allowed us to conduct an in‐depth study of the morphology of the inner coma. From the measurement of the dust emission structures expanding near the cometary nucleus in November–December 2013, we derived a slow rotation period of 47.8±1.2$$ 47.8\pm 1.2 $$ h.

Optical photometry of the UCM lists I and II [PDF]

open access: yesAstronomy & Astrophysics, 2001
We present Johnson B surface photometry for the UCM Survey galaxies. One-dimensional bulge-disk decomposition is attempted, discussing on fitting functions and computational procedures. The results from this decomposition, jointly with concentration indices and an asymmetry coefficient, are employed to study the morphological properties of these ...

First Light LBT AO Images of HR 8799 bcde at 1.65 and 3.3 Microns: New Discrepancies between Young Planets and Old Brown Dwarfs

open access: yes, 2012
As the only directly imaged multiple planet system, HR 8799 provides a unique opportunity to study the physical properties of several planets in parallel.

Chromatography in Downstream Processing of Recombinant Adeno‐Associated Viruses: A Review of Current and Future Practises

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Recombinant adeno‐associated virus (rAAV) has emerged as an attractive gene delivery vector platform to treat both rare and pervasive diseases. With more and more rAAV‐based therapies entering late‐stage clinical trials and commercialization, there is an increasing pressure on the rAAV manufacturing process to accelerate drug development ...

New Astronomical Observatory Design for the Detection and Tracking of Satellite Objects: The Satellite Robotic Observatory (SRO)

open access: yesRemote Sensing
Robotic Astronomical Observatories (RAOs) have provided very good results in different research projects in astrophysics/astronomy. Their applications in the detection, tracking, and identification of near-Earth objects have contributed to the ...

Unlocking the secrets of stellar haloes using combined star counts and surface photometry [PDF]

open access: yesMNRAS 421 (2012), 190, 2011
The stellar haloes of galaxies can currently be studied either through observations of resolved halo stars or through surface photometry. Curiously, the two methods appear to give conflicting results, as a number of surface photometry measurements have revealed integrated colours that are too red to be reconciled with the halo properties inferred from ...

bRing: An observatory dedicated to monitoring the $\beta$ Pictoris b Hill sphere transit [PDF]

open access: yes, 2017
Aims. We describe the design and first light observations from the $\beta$ Pictoris b Ring ("bRing") project. The primary goal is to detect photometric variability from the young star $\beta$ Pictoris due to circumplanetary material surrounding the ...

Detecting the Undetectable: Advances in Methods for Identifying Small Tau Aggregates in Neurodegenerative Diseases

open access: yesChemBioChem, EarlyView.
This review explores current methods for detecting and characterising small tau aggregates, which are increasingly recognised as key drivers of neurotoxicity in tauopathies. It discusses emerging techniques such as single‐molecule pull‐down (SiMPull), single‐molecule Förster resonance energy transfer (smFRET), and cryo‐electron tomography (cryo‐ET ...
