ARDIS: a Swedish historical handwritten digit dataset

CHEDDAD, Abbas | GRAHN, Håkan | HALL, Johan | KUSETOĞULLARI, Hüseyin | YAVARIABDI, Amir

This paper introduces a new image-based handwritten historical digit dataset named Arkiv Digital Sweden (ARDIS). The images in ARDIS dataset are extracted from 15,000 Swedish church records which were written by different priests with various handwriting styles in the nineteenth and twentieth centuries. The constructed dataset consists of three single-digit datasets and one-digit string dataset. The digit string dataset includes 10,000 samples in red–green–blue color space, whereas the other datasets contain 7600 single-digit images in different color spaces. An extensive analysis of machine l ...Daha fazlası

Background/aim: The present study aimed to define the clinical and laboratory criteria for predicting patients that will not benefit from invasive mechanical ventilation (IMV) treatment and determine the prediction of mortality and prognosis of these critical ill patients. Materials and methods: The study was designed as an observational, multicenter, prospective, and cross-sectional clinical study. It was conducted by 75 researchers at 41 centers in intensive care units (ICUs) located in various geographical areas of Turkey. It included a total of 1463 ICU patients who were receiving invasive ...Daha fazlası

Construction of efficient bioelectrochemical devices: Improved electricity production from cyanobacteria (Leptolyngbia sp.) based on π‐conjugated conducting polymer/gold nanoparticle composite interfaces

ÇEVİK, Emre | BÜYÜKHARMAN, Mustafa | YILDIZ, Hüseyin Bekir

In this study, gold electrodes (GE) were coated with conducting polymers to obtain a high photocurrent using cyanobacteria from a novel bioelectrochemical fuel cell. For this purpose, 4‐(4H‐ditiheno[3,2‐b:2',3'‐d]pyrol‐4‐yl) aniline and 5‐(4H‐dithieno[3,2‐b:2',3'‐d]pyrol‐4‐yl) napthtalane‐1‐amine monomers were coated on GE by performing an electropolymerization process. After that, gold nanoparticles (AuNP) were specifically modified by 2‐mercaptoethane sulfonic acid and p‐aminothiophenol to attach to the electrode surface. The conducting polymers GE coat was modified with functionalized AuNP ...Daha fazlası

Kazakhstan Country Image On The Websites Of Turkish Newspapers

BÜYÜKDOĞAN, Birol

The aim of this study was to examine the representation of Kazakhstan in the internet websites of Turkish newspapers. The study sample comprises the websites of Turkey's top four newspapers in terms of sales. The news reports were examined between October 1 and December 31, 2017. Data obtained were analyzed using the method of content analysis. The results revealed that the representation of Kazakhstan by the Turkish press is generally positive. Additionally, it revealed that politics, economics, and sports are top three topics discussed in the news. Most reports about politics, economics, cul ...Daha fazlası

Direct photon production at low transverse momentum in proton–proton collisions at √ s = 2.76 and 8 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Measurements of inclusive and direct photon production at midrapidity in pp collisions at s=2.76 and 8 TeV are presented by the ALICE experiment at the LHC. The results are reported in transverse momentum ranges of 0.4

Event-shape- and multiplicity-dependent identified particle production in pp collisions at 13 TeV with ALICE at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

Multiplicity-dependent measurements of identified particle production led to the discovery of collective-like behavior in pp collisions at the LHC. Better understanding of the effects attributed to well-understood physics, like multiple hard scatterings, is required to establish whether this behaviour is truly collective in origin. Experimentally, those effects can be controlled using event shapes, like transverse spherocity, which allows the classification of pp collisions either as jetty or isotropic events. The transverse momentum (p(T)) spectra of light-flavor hadrons in pp collisions meas ...Daha fazlası

ALICE results on system-size dependence of charged-particle multiplicity density in p-Pb, Pb-Pb and Xe-Xe collisions

KARASU UYSAL, Ayben | ALICE Collaboration

Particle production at LHC energies involves the interplay of hard (perturbative) and soft (non-perturbative) QCD processes. Global observables, such as the charged-particle multiplicity, are related to the initial geometry and the energy density produced in the collision. They are important to characterise relativistic heavy-ion collisions and to constrain model calculations. The LHC produced Xenon-Xenon collisions for the first time in October 2017. New results on the primary charged-particle pseudorapidity density, and its pseudorapidity and centrality dependence are presented for this ligh ...Daha fazlası

Multiplicity dependence of (anti-)deuteron production in pp collisions at s=7TeV

KARASU UYSAL, Ayben | ALICE Collaboration

In this letter, the production of deuterons and anti-deuterons in pp collisions at s=7 TeV is studied as a function of the charged-particle multiplicity density at mid-rapidity with the ALICE detector at the LHC. Production yields are measured at mid-rapidity in five multiplicity classes and as a function of the deuteron transverse momentum (pT). The measurements are discussed in the context of hadron � coalescence models. The coalescence parameter B2, extracted from the measured spectra of (anti-)deuterons and primary (anti-)protons, exhibits no significant pT-dependence for pT

Testing the system size dependence of hydrodynamical expansion and thermal particle production with π, K, p, and φ in Xe–Xe and Pb–Pb collisions with ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

We present new results on transverse momentum spectra, integrated yields, and mean transverse momenta of pions, kaons, and protons, as well as of phi-mesons for various centrality classes measured in Pb-Pb and Xe-Xe collisions at the LHC. This unique set of data allows us to investigate bulk particle production for very different systems at similar multiplicities. The chemical and kinetic freeze-out parameters are extracted via statistical-thermal and combined blast-wave fits to the data in heavy-ion collisions and are compared to results obtained in pp and p-Pb collisions at similar multiplic ...Daha fazlası

Measurements of anisotropic flow and flow fluctuations in Xe–Xe and Pb–Pb collisions with ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

Anisotropic flow is a key observable to characterise the system created in heavy-ion collisions, as it is sensitive to the system's initial state, transport properties, the equation of state and freeze-out conditions. In these proceedings we present the anisotropic flow coefficients of inclusive charged particles in Pb-Pb collisions at root s(NN) = 2.76 and 5.02 TeV, and in Xe-Xe collisions at root s(NN) = 5.44 TeV. The results are reported for a wide range of particle transverse momentum within the pseudo-rapidity range vertical bar eta vertical bar < 0.8 at different collision centralities. ...Daha fazlası
