The x-ray telescope of CAST [PDF]
, 2007 The CERN Axion Solar Telescope (CAST) has been in operation and taking data since 2003. The main objective of the CAST experiment is to search for a hypothetical pseudoscalar boson, the axion, which might be produced in the core of the sun.

Local sensitivity analysis of a supercritical extraction model
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study investigates the process of chamomile oil extraction from chamomile flowers. A parameter‐distributed model, consisting of a set of partial differential equations, was used to describe the governing mass transfer phenomena between solid and fluid phases under supercritical conditions using carbon dioxide as the solvent.

SIGMA and XTE observations of the soft X-ray transient XTEJ1755-324
, 1998 We present observations of the X-ray transient XTEJ1755-324 performed during summer 1997 with the XTE satellite and with the SIGMA hard X-ray telescope onboard the GRANAT observatory.

Laser &Photonics Reviews, EarlyView.Simultaneous temporal soliton self‐compression with simultaneous formation of a radial Townes profile is reported for millijoule pulses at 4.9 µm wavelength in ZnS. Pulses as short as 37 fs are generated in a 1‐kHz pulse train. The compression regime appears below the onset of filamentation, yielding two‐cycle pulses with 2.0 mJ energy which translates

Discovery of SXP265, a Be/X-ray binary pulsar in the Wing of the Small Magellanic Cloud
, 2014 We identify a new candidate for a Be/X-ray binary in the XMM-Newton slew survey and archival Swift observations that is located in the transition region of the Wing of the Small Magellanic Cloud and the Magellanic Bridge.

Reversal Asymmetry of Reciprocal Metasurface Enables Ultra‐Compact Varifocal Reflective Lens
Laser &Photonics Reviews, EarlyView.The possibility of breaking the reversal symmetry of a lens without violating reciprocity is demonstrated. The freedom provided is utilized to realize an ultra‐compact reflective varifocal lens‐doublet based on a flat metasurface lens and a piezoelectric actuated micromirror.
