Abstract. Polar stratospheric clouds (PSCs) have been observed from 2014 to 2018 the lidar observatory at Antarctic Concordia station (Dome C), included as a primary in NDACC (Network for Detection of Atmospheric Climate Change). Many these measurements performed coincidence with overpasses satellite-borne CALIOP (Cloud Aerosol Lidar Orthogonal Polarization) lidar, order perform comparison term...

A quasi-real time approach is used to investigate the relative influence of urban green space on individual’s experienced well-being. Using a diary-style survey instrument (the Day Reconstruction Method; Kahneman et al., 2004) combined with personal GPS trackers, the influence that visual exposure to natural and urban features has on the emotional experiences of everyday trips and activities is...

Here we propose and computationally demonstrate a quasi-planar metasurface consisting of arrays of pairs of concentric coaxial apertures in a metallic film. The structure relies on destructive interference between Fabry-Pérot modes excited in each aperture at resonance producing transmitted fields that interfere destructively leading to suppressed transmission. Conversely, we show that in the c...

We analyze the parsec-scale jet kinematics from 2007 June to 2018 December of a sample $\gamma$-ray bright blazars monitored roughly monthly with Very Long Baseline Array at 43 GHz under VLBA-BU-BLAZAR program. implement novel piece-wise linear fitting method derive 521 distinct emission knots total 3705 intensity images in 22 quasars, 13 BL Lacertae objects, and 3 radio galaxies. Apparent spee...

A high-resolution study of fragment-fragment-γ triple coincident measurements of the symmetric-mass fission exit-channel from the Si+Si reaction has been performed at the VIVITRON Tandem facility by using the EUROGAM Phase II γ-ray spectrometer. The bombarding energy Elab( Si) = 111.6 MeV has been chosen to populate a well known quasi-molecular resonance in Ni. Evidence is presented for a selec...

We report the results of a search for X-ray emission from quasar host clusters at moderate redshift using the ROSAT HRI. We detect no emission from the host clusters of 3C 263 (z=0.646) and PKS 2352-34 (z=0.706) to 3 limits of 3.26 and 2.86 10 ergs s 1 respectively (Ho=50, qo=1/2) for clusters with rcore=125 kpc and T=5 keV. These limits show that these quasar host clusters are not substantiall...
