Electromagnetic properties of the neutrinos in gamma-proton collision at the LHC
We have investigated non-standard and couplings via production in a
collision at the LHC. We obtain 95\% confidence level bounds on and couplings by considering three
different forward detector acceptances; , and . We show that the reaction provides more than eight orders of magnitude improvement in
neutrino-two photon couplings compared to LEP limits.Comment: 18 pages, 5 figure
Anomalous WWgamma couplings in gamma-proton collision at the LHC
We examine the potential of pp-> p gamma p -> p W q X reaction to probe
anomalous WWgamma couplings at the LHC. We find 95% confidence level bounds on
the anomalous coupling parameters with various values of the integrated
luminosity. We show that the reaction pp -> p gamma p -> p W q X at the LHC
highly improve the current limits.Comment: 12 pages,3 figure
Nanoscale tunnel field effect transistor based on a complex oxide lateral heterostructure
We demonstrate a tunnel field effect transistor based on a lateral
heterostructure patterned from an electron gas.
Charge is injected by tunneling from the /
contacts and the current through a narrow channel of insulating
is controlled via an electrostatic side gate. Drain-source
I/V-curves have been measured at low and elevated temperatures. The transistor
shows strong electric-field and temperature-dependent behaviour with a steep
sub-threshold slope %of up to as small as and a
transconductance as high as . A fully
consistent transport model for the drain-source tunneling reproduces the
measured steep sub-threshold slope.Comment: 20 pages, 6 figures, Supplementary material: 4 pages, 2 figure
The effect of electromagnetic properties of neutrinos on the photon-neutrino decoupling temperature
We examine the impact of electromagnetic properties of neutrinos on the
annihilation of relic neutrinos with ultra high energy cosmic neutrinos for the
process. For this process, photon-neutrino
decoupling temperature is calculated via effective lagrangian model beyond the
standard model. We find that photon-neutrino decoupling temperature can be
importantly reduced below the QCD phase transition with the model independent
analysis defining electromagnetic properties of neutrinos.Comment: 12 pages, 3 figures, published versio
Bottom trawl fishery discards in the Black Sea coast of Turkey
The purpose of this study is to determine the amount of bycatch and discardfish caught by bottom trawlers used in the Black Sea coasts of Turkey anddiscard changes depending on the depth. The study was conducted during theSeptember 2009 – April 2010 fishing season. Twenty-one bottom trawleroperations were sampled and the catch composition was determined. A total of 26species were caught, which included 22 species of fish, 2 species of arthropods,1 species of gastropods and 1 species of bivalves. Two of these were targetspecies (Mullusbarbatus, Merlangius merlangus), while 25 species werediscarded including trash fish and specimens below the legal size. A total of2142.76 kg of biomass was caught during the operations, of which 53.99 % bycatch.The weighted discard rate was determined as 42.06% and two different groupswere identified in discards (T1: 10-57 m, T2: 72-118 m) based on the depth. Significantdifferences were identified between these depth groups (p0.05) between theecological parameters of landings
Open borders, closed minds: the discursive construction of national identity in North Cyprus
The article investigates the discursive construction of a Turkish Cypriot national
identity by the newspapers in North Cyprus. It questions the representation and
reconstruction processes of national identity within the press and examines the
various practices employed to mobilize readers around certain national imaginings.
Using Critical Discourse Analysis, the article analyses news reports of the opening of
border crossings in Cyprus in 2003, based on their content, the strategies used in the
production of national identity and the linguistic means employed in the process. In this
way, the nationalist tendencies embedded in news discourses, as well as discriminatory
and exclusive practices, are sought out
