The Association of Universities for Research in Astronomy, et 
al.; Notice of Consolidated Decision on Applications for Duty-Free 
Entry of Scientific Instruments

    This is a decision pursuant to Section 6(c) of the Educational, 
Scientific, and Cultural Materials Importation Act of 1966 (Pub. L. 89-
651, as amended by Pub. L. 106-36; 80 Stat. 897; 15 CFR part 301). 
Related records can be viewed between 8:30 a.m. and 5:00 p.m. in Room 
3720, U.S. Department of Commerce, 14th and Constitution Avenue NW., 
Washington, DC.
    Comments: None received. Decision: Approved. We know of no 
instruments of equivalent scientific value to the foreign instruments 
described below, for such purposes as each is intended to be used, that 
was being manufactured in the United States at the time of its order.
    Docket Number: 13-052. Applicant: The Association of Universities 
for Research in Astronomy, Tucson, AZ 85719. Instrument: Enclosure 
control system for the Advanced Technology Solar Telescope. 
Manufacturer: AEC Engineering, part of the IDOM Group, Spain. Intended 
Use: See notice at 79 FR 6888, February 5, 2014. Comments: None 
received. Decision: Approved. We know of no instruments of equivalent 
scientific value to the foreign instruments described below, for such 
purposes as this is intended to be used, that was being manufactured in 
the United States at the time of order. Reasons: The instrument will be 
used to understand the nature of transient solar events which affect 
life on Earth by employing techniques such as augmenting pointing 
control of the Telescope at the Sun and augmenting control over the 
thermal environment during operational use. During normal sun-tracking 
operations, the Enclosure accessory shall provide complete protection 
of the Telescope (except for the M1 Assembly) from incoming solar 
radiation (insolation), the Enclosure accessory shall provide an 
unobstructed

optical path from the Sun to the M1 Assembly when the carousel and 
shutters are in any position within their allowable ranges of travel, 
and the Enclosure accessory skin shall be insulated to the extent 
required to ensure that the interior surface temperature can be 
maintained at +0 \0\F/-3.5\0\ relative to ambient temperature while the 
exterior skin temperature is at ambient minus 7.2 \0\F in all 
operational conditions.
    Docket Number: 13-054. Applicant: Regents of the University of 
Minnesota, School of Physics and Astronomy, Minneapolis, MN 55455-0149. 
Instrument: Yanus IV Laser Scan Head. Manufacturer: Till Photonics, 
Germany. Intended Use: See notice at 79 FR 6888, February 5, 2014. 
Comments: None received. Decision: Approved. We know of no instruments 
of equivalent scientific value to the foreign instruments described 
below, for such purposes as this is intended to be used, that was being 
manufactured in the United States at the time of order. Reasons: The 
instrument will be used to study the oligomeric state of EGFP tagged 
Retenoid X Receptor (RXR-EGFP) in the absence and presence of its 
ligand by PCH analysis, as well as follow its binding to DNA and other 
nuclear factors by conventional and scanning fluorescence correlation 
spectroscopy (FCS). The laser beam is continuously scanned in a 
circular fashion, which shows peaks and valleys which add contrast and 
give information about the scan radius, diffusion coefficient and 
particle concentrations that would be absent in conventional FCS. 
Conventional scan heads for laser microscopy have a finite distance 
between their scan axes, which introduces aberrations and vignetting 
into the scan. These distortions in the point spread function prohibit 
the quantitative imaging experiments. The Yanus IV scan head has been 
engineered with an effective zero optical distance between the scan 
axes, which maintains diffraction-limited performance across the entire 
scan field. This is the only instrument with zero effective optical 
distance between the scan axes.
