[NII] fine-structure emission at 122 and 205um in a galaxy at z=2.6: a globally dense star-forming interstellar medium

Doherty, M. J.; Geach, J. E.; Ivison, R. J.; Dye, S. (2020-12-23)

We present new observations with the Atacama Large Millimeter/sub-millimeter Array of the 122um and 205um fine-structure line emission of singly-ionised nitrogen in a strongly lensed starburst galaxy at z=2.6. The 122/205um ...

Experimental investigation and statistical analysis of additively manufactured onyx-carbon fiber reinforced composites

Piramanayagam, S. R.; Kalimuthu, M.; Nagarajan, R.; Sait, A. M. A. K.; Krishnamoorthy, R. K.; Ismail, S. O.; Siengchin, S.; Mohammad, F.; Al-Lohedan, H. (2020-12-16)

Availability of additive manufacturing (AM) has influenced the scientiﬁc community to improve on production and versatility of the components created with several associated technologies. Adding multiple substances through ...

Serendipitous discovery of a dusty disc around WDJ181417.84-735459.83

Egea, E. González; Koester, D.; Rogers, L. K.; Marocco, F.; Cooper, W. J.; Beamin, J. C.; Burningham, B.; Day-Jones, A.; Forbrich, J.; Pinfield, D. J. (2020-12-12)

Spectroscopic observations of white dwarfs reveal that many of them are polluted by exoplanetary material, whose bulk composition can be uniquely probed this way. We present a spectroscopic and photometric analysis of the ...

Animal fiber characterization and fiber loading effect on mechanical behaviors of sheep wool fiber reinforced polyester composites

Manivannan, J.; Rajesh, S.; Mayandi, K.; Rajini, N.; Ismail, S. O.; Mohammad, F.; Kuzman, M. K.; Al-Lohedan, H. A. (2020-12-06)

This study presents animal fiber characterization and the influence of various fiber loadings on mechanical properties of sheep hair fiber-reinforced polymer (SHFRP) composites. The sheep hair fibers (SHF) characterization ...

Coverage Probability of Cell-Free Massive MIMO Systems

Papazafeiropoulos, A. K.; Kourtessis, P.; Renzo, M. DI; Chatzinotas, S.; Senior, J. M. (IEEE, 2020-12-04)

Despite that ongoing and future networks become denser and increasingly irregular, prior works in the area of cell-free (CF) massive multiple-input-multiple-output (mMIMO) systems relied on the strong assumption of uniformly ...

Design of a Broadband Circularly Polarized Antenna by Using Axial Ratio Contour

Wen, L.; Gao, S.; Luo, Q.; Hu, W.; Sanz-Izquierdo, B. (2020-12)

A novel method of using axial ratio (AR) contour to design a broadband circularly polarized (CP) antenna is presented in this letter. By resolving a radiated CP wave into two orthogonal far-field components, the resulted ...

Cellulosic fiber based hybrid composites: A comparative investigation into their structurally influencing mechanical properties

Vignesh, V.; Balaji, A. N.; Rabi, B. R. M.; Rajini, N.; Ayrilmis, N.; Karthikeyan, M. K. V.; Mohammade, F.; Ismail, S. O.; Al-Lohedan, H. A. (2020-11-25)

This paper focuses on hybrid and twisted hybrid Indian mallow/roselle cellulosic fiber yarn mat reinforced polyester composites and effects of their wood sawdust filler. The composite materials were fabricated using ...

Statically Verified Refinements for Multiparty Protocols

Zhou, Fangyi; Ferreira, Francisco; Hu, Raymond; Neykova, Rumyana; Yoshida, Nobuko (2020-11-20)

With distributed computing becoming ubiquitous in the modern era, safe distributed programming is an open challenge. To address this, multiparty session types (MPST) provide a typing discipline for message-passing concurrency, ...

Low-power, high-linearity transconductor with a high tolerance for process and temperature variations

Zhao, Jing; Sun, Yichuang; Nie, Guigen; Simpson, Oluyomi; Xu, Weilin (2020-11-18)

A novel scheme for tunable complementary metal–oxide–semiconductor (CMOS) transconductor robust against process and temperature (PT) variations is presented. The proposed configuration is a voltage controlled circuit based ...

LeMMINGs. II. The e-MERLIN legacy survey of nearby galaxies. The deepest radio view of the Palomar sample on parsec scale

Baldi, R. D.; Williams, D. R. A.; McHardy, I. M.; Beswick, R. J.; Brinks, E.; Dullo, B. T.; Knapen, J. H.; Argo, M. K.; Aalto, S.; Alberdi, A.; Baan, W. A.; Bendo, G. J.; Corbel, S.; Fenech, D. M.; Gallagher, J. S.; Green, D. A.; Kennicutt, R. C.; Klöckner, H. -R.; Körding, E.; Maccarone, T. J.; Muxlow, T. W. B.; Mundell, C. G.; Panessa, F.; Peck, A. B.; Pérez-Torres, M. A.; Romero-Cañizales, C.; Saikia, P.; Shankar, F.; Spencer, R. E.; Stevens, I. R.; Varenius, E.; Ward, M. J.; Yates, J. (2020-11-17)

We present the second data release of high-resolution ($\leq0.2$ arcsec) 1.5-GHz radio images of 177 nearby galaxies from the Palomar sample, observed with the e-MERLIN array, as part of the LeMMINGs (Legacy e-MERLIN ...
