Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV
No full textAbstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d? t) and chromomagnetic (?? t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb?1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048?0.087+0.095(stat)?0.029+0.020(syst),??t=?0.024?0.009+0.013(stat)?0.011+0.016(syst), and a limit is placed on the magnitude of | d? t| < 0.03 at 95% confidence level.

Thermal management of electric vehicle battery cells with homogeneous coolant and temperature distribution
No full textElectric vehicles play an integral role in eliminating pollution related to transportation, especially if the electricity is generated via renewable sources. However, storing electricity onboard requires many battery cells. If the temperature of the cells is not strictly regulated, their capacity decreases in time, and they may burn or explode due to thermal runaway. Battery thermal management systems emerged for safe operations by keeping the battery cell temperatures under limit values. However, the current solutions do not yield uniform temperature distribution for all the cells in a pack. Here, we document that constant temperature distribution can be achieved with uniform coolant distribution to the channels located between batteries. The design process of the developed battery pack begins with a design used in current packs. Later, how the shape of the distributor channel affects flow uniformity is documented. Then, the design complexity was increased to satisfy the flow uniformity condition, which is essential for temperature uniformity. The design was altered based on a constructal design methodology with an iterative exhaustive search approach. The uncovered constructal design yields a uniform coolant distribution with a maximum of 0.81% flow rate deviation along channels. The developed design is palpable and easy to manufacture relative to the tapered manifold designs. The results also document that the peak temperature difference between the cells decreases from a maximum of 12K to 0.4K. Furthermore, homogenous distribution of air is one of the limiting factors of the development of metal-air batteries. This paper also documents how air can be distributed uniformly to metal-air battery cells in a battery pack
Magnetic mechanism for the biological functioning of hemoglobin
No full textPubMed: 32444622The role of magnetism in the biological functioning of hemoglobin has been debated since its discovery by Pauling and Coryell in 1936. The hemoglobin molecule contains four heme groups each having a porphyrin layer with a Fe ion at the center. Here, we present combined density-functional theory and quantum Monte Carlo calculations for an effective model of Fe in a heme cluster. In comparison with these calculations, we analyze the experimental data on human adult hemoglobin (HbA) from the magnetic susceptibility, Mossbauer and magnetic circular dichroism (MCD) measurements. In both the deoxygenated (deoxy) and the oxygenated (oxy) cases, we show that local magnetic moments develop in the porphyrin layer with antiferromagnetic coupling to the Fe moment. Our calculations reproduce the magnetic susceptibility measurements on deoxy and oxy-HbA. For deoxy-HbA, we show that the anomalous MCD signal in the UV region is an experimental evidence for the presence of antiferromagnetic Fe-porphyrin correlations. The functional properties of hemoglobin such as the binding of O-2, the Bohr effect and the cooperativity are explained based on the magnetic correlations. This analysis suggests that magnetism could be involved in the functioning of hemoglobin
Extraction and validation of a new set of CMS pythia8 tunes from underlying-event measurements
No full textPubMed: 31976986New sets of CMS underlying-event parameters ("tunes") are presented for the pythia8 event generator. These tunes use the NNPDF3.1 parton distribution functions (PDFs) at leading (LO), next-to-leading (NLO), or next-to-next-to-leading (NNLO) orders in perturbative quantum chromodynamics, and the strong coupling evolution at LO or NLO. Measurements of charged-particle multiplicity and transverse momentum densities at various hadron collision energies are fit simultaneously to determine the parameters of the tunes. Comparisons of the predictions of the new tunes are provided for observables sensitive to the event shapes at LEP, global underlying event, soft multiparton interactions, and double-parton scattering contributions. In addition, comparisons are made for observables measured in various specific processes, such as multijet, Drell-Yan, and top quark-antiquark pair production including jet substructure observables. The simulation of the underlying event provided by the new tunes is interfaced to a higher-order matrix-element calculation. For the first time, predictions from pythia8 obtained with tunes based on NLO or NNLO PDFs are shown to reliably describe minimum-bias and underlying-event data with a similar level of agreement to predictions from tunes using LO PDF sets
Observation of nuclear modifications in W± boson production in pPb collisions at √s(NN)=8.16 TeV
No full textThe production of W-+/- bosons is studied in proton-lead (pPb) collisions at a nucleon-nucleon centre-of-mass energy of root s(NN) = 8.16 TeV. Measurements are performed in the W-+/- -> mu(+/-)nu(mu) channel using a data sample corresponding to an integrated luminosity of 173.4 +/- 6.1 nb(-1), collected by the CMS Collaboration at the LHC. The number of positively and negatively charged W bosons is determined separately in the muon pseudorapidity region in the laboratory frame vertical bar eta(mu)(lab)vertical bar 25 GeV/c. The W-+/- boson differential cross sections, muon charge asymmetry, and the ratios of W-+/- boson yields for the proton-going over the Pb-going beam directions are reported as a function of the muon pseudorapidity in the nucleon-nucleon centre-of-mass frame. The measurements are compared to the predictions from theoretical calculations based on parton distribution functions (PDFs) at next-to-leading-order. The results favour PDF calculations that include nuclear modifications and provide constraints on the nuclear PDF global fits. (C) 2019 The Author(s). Published by Elsevier B.V
Performance of multicast MISO-OFDM systems
No full text13th European Wireless Conference: Enabling Technologies for Wireless Multimedia Communications, EW 2007In this paper, we evaluate the performance of multicast OFDM systems with single and multiple transmit antennas. We have shown that it is possible to increase the data rate of multicast OFDM systems by selecting the users with good channel for each subcarrier. For the single transmit antenna case, the resource allocation has been applied using the two-step algorithm where subcarrier allocation and bit loading are performed separately. For the multiple transmit antennas case, we have proposed a suboptimal algorithm using a set of precoding vectors. In this study, we present the simulation results of the complete transmission chain where we have associated the resource allocation algorithms with a powerful erasure code. The results show that the proposed algorithms outperform the classical worst case algorithm for both single and multiple transmit antennas. © EW 2007 - 13th European Wireless Conference: Enabling Technologies for Wireless Multimedia Communications.

Nguyen, Thong Q./0000-0003-3954-5131A search for charged Higgs bosons (H-+/-) decaying into a top and a bottom quark in the all-jet final state is presented. The analysis uses LHC proton-proton collision data recorded with the CMS detector in 2016 at root s = 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1). No significant excess is observed above the expected background. Model-independent upper limits at 95% confidence level are set on the product of the H-+/- production cross section and branching fraction in two scenarios. For production in association with a top quark, limits of 21.3 to 0.007 pb are obtained for H-+/- masses in the range of 0.2 to 3 TeV. Combining this with a search in leptonic final states results in improved limits of 9.25 to 0.005 pb. The complementary s-channel production of an H-+/- is investigated in the mass range of 0.8 to 3 TeV and the corresponding upper limits are 4.5 to 0.023 pb. These results are interpreted using different minimal supersymmetric extensions of the standard model.BMBWF (Austria); FWF (Austria)Austrian Science Fund (FWF); FNRS (Belgium)Fonds de la Recherche Scientifique - FNRS; FWO (Belgium)FWO; CNPq (Brazil)National Council for Scientific and Technological Development (CNPq); CAPES (Brazil)CAPES; FAPERJ (Brazil)Carlos Chagas Filho Foundation for Research Support of the State of Rio de Janeiro (FAPERJ); FAPERGS (Brazil)Foundation for Research Support of the State of Rio Grande do Sul (FAPERGS); FAPESP (Brazil)Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP); MES (Bulgaria); CERN; CAS (China)Chinese Academy of Sciences; MoST (China)Ministry of Science and Technology, China; NSFC (China)National Natural Science Foundation of China (NSFC); COLCIENCIAS (Colombia)Departamento Administrativo de Ciencia, Tecnologia e Innovacion Colciencias; MSES (Croatia); CSF (Croatia); RPF (Cyprus); SENESCYT (Ecuador); MoER (Estonia); ERC IUT (Estonia)Estonian Research Council; PUT (Estonia); ERDF (Estonia)European Union (EU); Academy of Finland (Finland)Academy of Finland; MEC (Finland); HIP (Finland); CEA (France)French Atomic Energy Commission; CNRS/IN2P3 (France)Centre National de la Recherche Scientifique (CNRS); BMBF (Germany)Federal Ministry of Education & Research (BMBF); DFG (Germany)German Research Foundation (DFG); HGF (Germany); GSRT (Greece)Greek Ministry of Development-GSRT; NKFIA (Hungary); DAE (India)Department of Atomic Energy (DAE); DST (India)Department of Science & Technology (India); IPM (Iran); SFI (Ireland)Science Foundation Ireland; INFN (Italy)Istituto Nazionale di Fisica Nucleare (INFN); MSIP (Republic of Korea); NRF (Republic of Korea); MES (Latvia); LAS (Lithuania); MOE (Malaysia); UM (Malaysia); BUAP (Mexico); CINVESTAV (Mexico); CONACYT (Mexico)Consejo Nacional de Ciencia y Tecnologia (CONACyT); LNS (Mexico); SEP (Mexico); UASLP-FAI (Mexico); MOS (Montenegro); MBIE (New Zealand); PAEC (Pakistan); MSHE (Poland); NSC (Poland); FCT (Portugal)Portuguese Foundation for Science and Technology; JINR (Dubna); MON (Russia); RosAtom (Russia); RAS (Russia)Russian Academy of Sciences; RFBR (Russia)Russian Foundation for Basic Research (RFBR); NRC KI (Russia); MESTD (Serbia); SEIDI (Spain); CPAN (Spain); PCTI (Spain); FEDER (Spain)European Union (EU); MOSTR (Sri Lanka); Swiss Funding Agencies (Switzerland); MST (Taipei); ThEPCenter (Thailand); IPST (Thailand); STAR (Thailand); NSTDA (Thailand); TUBITAK (Turkey)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK); TAEK (Turkey)Ministry of Energy & Natural Resources - Turkey; NASU (Ukraine); STFC (United Kingdom)Science & Technology Facilities Council (STFC); DOE (U.S.A.)United States Department of Energy (DOE); NSF (U.S.A.)National Science Foundation (NSF); Marie-Curie program (European Union)European Union (EU); Horizon 2020 Grant (European Union)European Union (EU) [675440, 752730, 765710]; Leventis Foundation; A.P.

Mimarlıkta ve sanatta mekanizmaların kullanımı ve tasarımı üzerine bir çalışma
No full textThesis (Master)--Izmir Institute of Technology, Architecture, Izmir, 2020Includes bibliographical references (leaves: 185-198)Text in English; Abstract: Turkish and EnglishThis study consists of research on developmental processes, fundamentals, kinematic properties, and design methods of art and architectural examples that involve mechanisms and a proposal of a novel method of designing polygonal deployable surfaces. The effect of motion studies on art and architecture is analyzed from the first technical studies of motion and portable examples of architecture. The pre-industrial automata, acoustic designs, musical instruments, water-lifting devices, and aqueducts were designed by artists and architects as well; windmills that are the first rotating structures, clocks, clock towers, construction machines and early examples of movable bridges are examined. The kinematic properties and fundamentals of mechanisms are analyzed. The kinematic structural analyses of contemporary art and architectural products are conducted by drawing kinematic diagrams, demonstrating link and joint types and numbers; and mobility calculations. The primary units and assembly methods of them are examined. Strengthening the bond among the fields of kinetic architecture, art and mechanism science is intended. The present study is the first source in which examples from the related fields and corresponding kinematic science are explicitly transmitted for artists and architects. Finally, a novel design method for polygonal deployable surfaces that is adaptable to climatic, functional, visual and/or social needs is developed. The method starts with the kinematic design of the triangular primary unit, which is topologically Bennett's plano-spherical mechanism. The planar position provides covering surfaces, while the spherical linkage generates a 3D dynamic form during movement. The design is adapted to polygons and multiplied in Archimedean tilings. A single actuator can drive all designs. The modularity provides designs versatility and flexibility.Bu tezde mimari ve sanat alanlarından mekanizma içeren örneklerin gelişim süreçleri, temel prensipleri, kinematik özellikleri ve tasarım yöntemleri incelenmiş; sonrasında tek serbestlik dereceli, çokgenlerden oluşan hareketli yüzeylerin tasarımları için bir yöntem önerisi geliştirilmiştir. Hareket çalışmalarının mimariyi ve sanatı şekillendirme biçimi, hareketin teknik olarak ilk incelendiği dönemlerden ve mimarinin ilk portatif örneklerinden başlanarak ele alınmıştır. Endüstri öncesi dönemde sanatçılar ve mimarlar tarafından da tasarlanan otomatlar, akustik tasarımlar ve müzik aletleri, suyu yukarıya taşıyan araçlar ve su kemerleri, dönme kabiliyetine sahip ilk yapılardan rüzgâr çarkları, saatler ve saat kuleleri, inşaat makineleri ve hareketli köprülerin ilk örnekleri araştırılmıştır. Mekanizmaların kinematik özellikleri, temel kavramlarıyla birlikte incelenmiştir. Sanat ve mimarlık alanlarından güncel örneklerin kinematik yapısal analizleri ise kinematik diyagramları çizilerek, uzuv ve mafsal tipleriyle sayıları gösterilerek, serbestlik dereceleri hesaplanarak ortaya konmuştur. Tasarımların temel birimleri ve birleşme özellikleri incelenmiştir. Kinetik mimari, sanat ve mekanizma bilimleri arasındaki köprüleri güçlendirmesi amaçlanmıştır. Mimarlar ve sanatçılar için oluşturulan, bu alanlardaki örnekler ve özellikler incelenip temel kinematik bilgisinin süzülerek toplandığı ilk kaynaktır. Son olarak iklimsel, işlevsel, görsel ve/veya sosyal ihtiyaçlara adapte olabilecek, düzgün çokgenlerden oluşan, açılıp kapanabilen yüzeyler için yeni bir tasarım yöntemi önerilmiştir. Bu yöntem üçgensel temel birimin kinematik tasarımıyla başlar. Bu birim topolojik olarak Bennett'in düzlemsel ve küresel bağlantı biçimini kullanır. Düzlemsel form, düz yüzeyleri kapatmaya uygundur; ayrıca kullanılan küresel bileşen, hareket sırasında 3B dinamik bir form oluşmasını sağlar. Ardından tasarım, çokgenlere adapte edilerek düzenli ve yarı düzenli teselasyonlarda çoğaltılır. Oluşan tasarımların hepsi tek bir motorla kontrol edilebilir. Modüler olması ise tasarımlara çok yönlülük ve esneklik sağlar
Indoor Air Levels and Health Risk Assessment of Carbon Tetrachloride Emitted from Toilet-Bowl Cleaners
No full textİç hava kirliliği açısından temizlik ürünleri kullanımı önemli bir kaynak oluşturmak-tadır. Bir Uçucu Organik Bileşik (UOB) olan karbon tetraklorürün emisyonu, diğer UOB’ler ile birlikte klorlanmış çeşme suyundan, özellikle su sıcaklığının artırıldığı yıkanma, çamaşır ve bulaşık yıkanması sırasında oluşur. Bununla birlikte, ağartıcı olarak hipoklorit (çamaşır suyu) içeren temizlik ürünlerinde ve kullanımı sırasında, çamaşır suyu ile organik maddelerin reaksiyona girmesiyle oluşumu bu bileşik için göreceli çok daha güçlü bir kaynak oluşturmaktadır. Karbon tetraklorürün hem kro-nik-toksik hem de karsinojenik sağlık etkileri olması sebebiyle bu temizlik ürünlerinin kullanımı durumunda iç ortam havasından etkin bir havalandırma ile uzaklaştırılma-sı gerekmektedir. Bu çalışmada, karbon tetraklorürün tuvalet ve banyolarda kullanı-lan klozet ve rezervuar tipi temizleyicilerden emisyonu deneysel olarak incelenmiş, iç hava düzeyleri modelleme ile tahmin edilmiş, solunum yoluyla maruziyet için kanser riski değerlendirmesi yapılmıştır. Ürünlerin emisyon potansiyeli tepe boşluğu katı fazlı mikroekstraksiyonu takiben GC/MS yöntemiyle incelenmiş, iç hava düzeylerinin modellenmesi için 8,9 m3 oda hacmi ve 0,5 ach hava değişimi hızı kullanılmıştır. Kul-lanılan bu hız ile ürünlerin kullanımından kaynaklanan karbon tetraklorür konsant-rasyonun sadece %0,6’lık kısmı uzaklaştırılabilmektedir. Ortalama ve 95. yüzdelik kanser risk değerleri kabul edilebilir risk olan milyonda birin altındadır ancak ürün-ler birer iç ortam karbon tetraklorür kaynağı oluşturmaktadır.The use of household cleaning products constitute an important source of indoor air pollution. Carbon tetrachloride is a volatile organic compound (VOC) emitted from chlorinated water especially when heated for example for showering and washing clothes / dishes, along with other VOCs. However, hypochlorite (bleach) containing household cleaning products and their use is a relatively much stronger source of the compound due to reaction of bleach with organic matter. Because carbon tetra-chloride has both chronic-toxic and carcinogenic health effects, removing it with an effective ventilation is necessary. In this study, the emission of carbon tetrachloride from automatic toilet bowl and reservoir cleaners was investigated experimentally. The emission potential of the products was studied by headspace - solid phase micro-extraction - GC/MS method, indoor air levels were modeled for 8,9 m3 bathroom vol-ume and 0,5 ach air exchange rate, and associated carcinogenic risks were estimated. Only 0,6% of the carbon tetrachloride concentration resulting from the use of the products could be removed at the specified conditions. The mean and 95th percentile risk values for cancer are below one-in-a-million acceptable risk level, but the prod-ucts are sources of carbon tetrachloride
Kuantum yürüyüşü: Uzay serbestlik dereceleri arasında dolanıklık ve çok fotonlu yürüyüşlerde girişim
No full textThesis (Master)--Izmir Institute of Technology, Physics, Izmir, 2020Includes bibliographical references (leaves: 61)Text in English; Abstract: Turkish and EnglishQuantum walks can be described as quantum analogues of classical random walks. In quantum walks, the direction of the walker is dictated by the quantum state of a coin in a coherent fashion. Unlike classical random walk with a fair coin, quantum walk has non-Markovian property. First, we studied 2-D quantum walk analytically and numerically with one-walker and two entangled coins to investigate the transfer of the entanglement in initial coins state to spatial degrees of freedom. The coins are Hadamard Coin, Fourier Coin, among which the Fourier coin generates entanglement, thus increase entanglement between spatial degrees of freedom. Here we calculated the amount of entanglement using negativity. In the second part we studied average photon number correlations for 1-D quantum walk with many body bosonic walkers, like different light sources, to investigate quantum interference effects and we showed the second-order intensity correlations function in terms of the probability amplitudes of the 1-D quantum walk with Hadamard coin. We compared the resulting correlations for various initial many photon states.Kuantum yürüyüşleri, klasik rastgele yürüyüşünün kuantum benzeri olarak tanımlanabilir. Kuantum yürüyüşlerinde yürüyücünün gideceği yön bir kuantum parasının kuantum durumuna göre belirlenir.Klasik rastgele yürüyüşlerin aksine kuantum yürüyüşleri Markov özelliklerine sahip değildir. Bu tezde ilk bölümde 2 boyuttaki kuantum yürüyüşlerde, başlangıçta kuantum paralar arasında bulunan dolanıklığın uzay serbestlik derecelerine transferini inceledik. Kullanılan kuantum paralar Hadamard ve Fourier paralar olarak seçidi. Hadamard parasının aksine Fourier parası her adımda dolanıklık yaratmaktadır. Dolanıklık miktarı "Negatiflik" metodu kullanılarak hesaplandı. İkinci bölümde ortalama foton sayıları üzerinden 1 boyutta çok fotonlu kuantum yürüyüşlerdeki kuantum girişim etkilerini ve 2. mertebe yoğunluk korelasyonlarını Hadamard para ile yapılan 1 boyutta kuantum yürüyüşünün olasılık genlikleri üstünden gösterdik ve farklı başlangıç durumlarına sahip sonuçları birbirleriyle karşılaştırdık
