The blazar PKS 1510-089 was the first of the flat spectrum radio quasar type, which had been detected simultaneously by a ground based Cherenkov telescope (H.E.S.S.) and the LAT instrument on board the Fermi satellite. Given the strong broad line region emission defining this blazar class, and the resulting high optical depth for VHE (E > 100 GeV) γ-rays, it was surprising to detect VHE emissio...

In this work a distributed video surveillance system based on a Client-Server architecture is presented. The proposed system is accessible from portable devices such as tablets, smartphones, etc. In a typical real-world scenario, for example in homeland security, it is useful to have portable devices that can receive in real-time a frame or a sequence of frames coming from a selected camera to ...

Abstract We perform correlation and periodicity search analyses on long-term multiband light curves of the flat-spectrum radio quasar PKS 1510−089 observed by space-based Fermi-Large Area Telescope in γ -rays, SMARTS Steward Observatory telescopes optical near-infrared (NIR), 13.7 m telescope Metsähovi Radio between 2008 2018. The z -transform discrete function method is applied to study possib...

The Dirac spin liquid ground state of the spin 1/2 Heisenberg kagome antiferromagnet has potential instabilities. This has been suggested as the reason why it does not emerge as the ground state in large-scale numerical calculations. However, previous attempts to observe these instabilities have failed. We report on the discovery of a projected BCS state with lower energy than the projected Dir...

Using structure-directing agents, pore space partitions of a Zn-phosphonocarboxylate framework have been achieved. Selective adsorption of CO(2) over N(2) has been greatly improved from ca. 9 : 1 to 94 : 1.

The flat spectrum radio quasar (FSRQ) PKS 1510−089 is known for its complex multiwavelength behaviour and it one of only a few FSRQs detected in very-high-energy (VHE, E > 100 GeV) γ rays. VHE -ray observations with H.E.S.S. MAGIC late May early June 2016 resulted the detection an unprecedented flare, which revealed, first time, intranight variability this source. While common timescale 1.5 ...

MagSaki software was developed for the magnetic analysis of dinuclear high-spin cobalt(II) complexes. This software performs magnetic analysis to determine magnetic parameters using several types of theoretical calculations, such as the following: (1) a mononuclear complex in an isotropic octahedral field, (2) a mononuclear complex in an axially distorted octahedral field, (3) a dinuclear compl...

The preparation and spectroscopic characterization of a CO-inhibited [FeFe] hydrogenase with a selectively (57)Fe-labeled binuclear subsite is described. The precursor [(57)Fe2(adt)(CN)2(CO)4](2-) was synthesized from the (57)Fe metal, S8, CO, (NEt4)CN, NH4Cl, and CH2O. (Et4N)2[(57)Fe2(adt)(CN)2(CO)4] was then used for the maturation of the [FeFe] hydrogenase HydA1 from Chlamydomonas reinhardti...

The covid-19 pandemic has exacerbated access problems in general practice and patients have reported finding it difficult to book appointments treatment, a report by Healthwatch found.1 The watchdog said that GPs must prioritise telling they are open for face-to-face wherever possible. Its latest looked at how had changed the way people their GP this affected experience of care. It was based ...
