Anomaly Detection Search for New Resonances Decaying Into a Higgs Boson and a Generic New Particle X in Hadronic Final States Using √s=13 Tev Pp Collisions With the Atlas Detector
No full textA search is presented for a heavy resonance Y decaying into a Standard Model Higgs boson H and a new particle X in a fully hadronic final state. The full Large Hadron Collider run 2 dataset of proton-proton collisions at root s =13 TeV collected by the ATLAS detector from 2015 to 2018 is used and corresponds to an integrated luminosity of 139 fb(-1). The search targets the high Y-mass region, where the H and X have a significant Lorentz boost in the laboratory frame. A novel application of anomaly detection is used to define a general signal region, where events are selected solely because of their incompatibility with a learned background-only model. It is constructed using a jet-level tagger for signal-model-independent selection of the boosted X particle, representing the first application of fully unsupervised machine learning to an ATLAS analysis. Two additional signal regions are implemented to target a benchmark X decay into two quarks, covering topologies where the X is reconstructed as either a single large-radius jet or two small-radius jets. The analysis selects Higgs boson decays into bb, and a dedicated neural-network-based tagger provides sensitivity to the boosted heavy-flavor topology. No significant excess of data over the expected background is observed, and the results are presented as upper limits on the production cross section sigma(pp -> Y -> XH -> qqbb) for signals with m(Y) between 1.5 and 6 TeV and m(X) between 65 and 3000 GeV.NSF, United States of America; BCKDF; CANARIE; CRC, Canada [PRIMUS 21/SCI/017, UNCE SCI/013]; Czech Republic; European Cooperation in Science and Technology (COST); ERC; ERDF; European Union; Investissements d'Avenir Labex, Investissements d'Avenir Idex; ANR, France; DFG; AvH Foundation, Germany; EU-ESF; Binational Science Foundation-National Science Foundation (BSF-NSF); MINERVA, Israel; NCN; La Caixa Banking Foundation; CERCA Programme Generalitat de Catalunya; PROMETEO; Gran Gustafssons Stiftelse, Sweden; Royal Society; Leverhulme Trust, United Kingdom; Nordic Grid Facility (NDGF) (Denmark, Norway, Sweden); KIT/GridKA (Germany); ASGC (Taiwan); BNL (USA)This research was supported by the National Natural Science Foundation of China(U21A20132).r Yerevan Physics Institute (YerPhI) , Armenia; ARC, Australia; BMWFW and FWF, Austria; ANAS, Azerbaijan; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; ANID, Chile; CAS, MOST and NSFC, China; Minciencias, Colombia; MEYS CR, Czech Republic; DNRF and Danish Natural Science Council (DNSRC) , Denmark; IN2P3-CNRS and CEA-Fundamental Research Division/IRFU = Institute of Research into the Fundamental Laws of the Universe, France; Shota Rustaveli National Science Foundation of Georgia (SRNSFG) , Georgia; BMBF, HGF and MPG, Germany; General Secretariat for Research and Innovation (GSRI) , Greece; Research Grants Council (RGC) and Hong Kong Special Administrative Region (SAR) , China; ISF and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; NWO, Netherlands; Research Council of Norway (RCN) , Norway; MEiN, Poland; FCT, Portugal; Ministry of National Education (MNE) /IFA, Romania; Ministry of Education, Science and Technological Development (MESTD) , Serbia; Ministry of Education, Science, Research and Sport (MSSR) , Slovakia; ARRS and Ministry of Education, Science and Sport (MIZ ; Scaron;) , Slovenia; DSI/NRF, South Africa; MICINN, Spain; Swedish Research Council (SRC) and Wallenberg Foundation, Sweden; State Secretariat for Education, Research and Innovation (SERI) , SNSF and Cantons of Bern and Geneva, Switzerland; MOST, Taiwan; TENMAK, Turkiye; STFC, United Kingdom; DOE andr NSF, United States of America.

Detection of the Coordinates of the Bee Swarm in the Sky Through Image Processing
No full text6th International Conference on Sustainable Science and Technology (ICSuSaT-2023) 14-16 July 2023, İstanbul-TURKİYEBy scattering pollen to flowers, bees allow plants and trees to bear fruit and disperse their seeds. This important task of bees in life continues the oxygen cycle, which is vital for humans. To put it briefly, a large part of life on earth depends on bees doing their job. In recent years, there has been an annual decrease in the number of bee colonies. For this reason, it is of great importance to keep the bee population under control and to prevent its decline. In this study, the x and y coordinates of a bee swarm in the sky were obtained using the MATLAB program. For this purpose, erosion, one of the morphological image processing methods, was used. In this way, objects other than bees in the photograph used in image processing were removed. With the developed algorithm, the coordinates were determined in the photograph where only the bees were visible. The obtained coordinates are written on the command line of the MATLAB program. Thus, the instantaneous location of the bees could be determined properly

As a result, user activities have become an important resource for various sociological studies. In this study, we proposed machine learning methods that utilize text-based and interaction-based features to predict the opinions of users who post messages in Turkish. We also performed zero-shot classification using ChatGPT. We labeled 4,502 accounts that posted during the Turkey Presidential election in 2018 according to the candidates they supported. In our experiments with the dataset we created, we achieved a classification accuracy of 0.831 for users.IEEE,TUBITAK BILGEM,Turkcel
Modernite, Terbiye ve Bellek: Erken Cumhuriyet Dönemi Başkent Ankara’da Tiyatro Sahnesi
No full textState Theater’s archive, State Theaters Refik Ahmet Sevengil Theater Library, Koç University Vehbi Koç Ankara Studies Research Center (VEKAM) archival sources, and Presidency of the Republic of Türkiye Directorate of State Archives and Turkish Grand National Assembly reports. In the light of the documents identified, a general picture of the theater scene, one of the most important actors of the cultural and artistic environment in the capital Ankara in the Early Republican period, was tried to be created.In the early years of the Republic, Ankara, as the intellectual and administrative space of Turkish modernization, turned into a laboratory where the futurist ideology was projected, the ideals of the new country and the way of life were positioned, and reforms in all areas of life were realized. Mustafa Kemal Atatürk's view that a modern society could be built within the framework of cultural developments, his understanding of utilizing the universality and educational value of art, and visual representations were seen as key elements in strengthening national community ties and transferring the codes of the new memory. Ankara's transformation into a modern capital city marks a process of change/transformation, the integration, and consumption of modern life practices into daily life. The messages/codes contained in activities such as theaters, concerts, and exhibitions, which the leaders of the Republic and the civil servants experienced, modeled, and encouraged for the people of Ankara were expected to spread throughout Anatolia, and the modern Turkish society that would emerge was defined as the only force that would ensure the permanence of the revolution. This article focuses on the theatrical activities followed in the capital between 1923 and 1950 and draws attention to the contribution of the Ankara State Conservatory and Tatbikat Stage to the cultural and artistic environment, as well as the establishment of the State Theater and Opera. It discusses the development of theater activities followed in Ankara, the basis on which they developed, the dynamics and movements of the theater scene, and how they became institutionalized. The relationship of the stage with the city and the urbanite was explored through the publications of the period and the documents of the Ankara Community House, and after the institutionalization of the theater stage, through the Ankara State ConservatoryDevlet Tiyatroları Arşivi, Devlet Tiyatroları Refik Ahmet Sevengil Tiyatro Kütüphanesi, Koç Üniversitesi Vehbi Koç Ankara Araştırmaları Uygulama ve Araştırma Merkezi (VEKAM) Arşivi verileriyle T.C.

Bu makalede, 19231950 yılları arasında başkentte takip edilen tiyatro etkinliklerine odaklanılmış, Ankara Devlet Konservatuvarı ve Tatbikat Sahnesi’nin kültür ve sanat ortamına katkısı ile Devlet Tiyatro ve Operası kuruluşuna dikkat çekilmiştir. Ankara’da takip edilen tiyatro etkinliklerinin nasıl bir zeminde gelişim gösterdiği, tiyatro sahnesinin devinimi ve dinamikleri ile nasıl kurumsallaştığı ele alınmıştır. Sahnenin kent ve kentli ile kurduğu ilişki, dönemin yayın organları ve Ankara Halkevi dokümanları aracılığıyla, tiyatro sahnesinin kurumsallaşmasının ardından ise Ankara Devlet Konservatuvarıdeğişimlerin/dönüşümlerin yaşandığı, modern yaşam pratiklerinin gündelik hayata entegre edildiği ve tüketildiği bir süreci işaret etmektedir. Cumhuriyet liderleri ile memur kesimin deneyimleyerek, Ankara halkına örneklediği ve özendirdiğiCumhuriyet’in erken yıllarında Ankara, Türk modernleşmesinin düşünsel ve yönetsel mekânı olarakgelecekçi ideolojinin projelendirildiği, yeni ülke idealleri ile yaşama biçiminin konumlandığı, hayatın her alanına dair reformların gerçekleştiği bir laboratuvara dönüşmüştür.

A Novel Approach for Measurement and Decomposition of the Economywide Costs of Shutting Down Tourism and Related Service Sectors Against Covid-19
No full textThe trade-off between desirable public health outcomes and undesirable economic outcomes of anti-pandemic measures forces policy makers everywhere to seek the right combination of measures to balance the public health concerns against employment and income considerations. This article describes a novel input-output approach to assessing economywide costs of shutting down tourism and related sectors to curb the spread of COVID-19. Our framework allows for a decomposition of the total effects of shutdowns into sectoral output losses resulting from (i) suspension of the delivery of inputs to other sectors, (ii) termination of the demand for inputs produced by these sectors, and (iii) the interruption of payments to the owners of factors of production employed in the sectors ordered to shut down. We illustrate the use of this methodological framework to measure and decompose the effects of recent shutdown orders issued in Turkey, a country of major tourism activity
Go/Zno-based All-Solid Photo-Supercapacitors: Effect of Go:zno Ratio on Composite Properties and Device Performance
No full textThe development of photo-supercapacitors (PSC), which is an important step towards more efficient use of solar energy and reducing the carbon footprint, will be possible with a better understanding and manipulation of the properties of photo-active dual-effect electrodes used in these devices. This work demonstrates the existence of critical ratios for graphene oxide/zinc oxide (GO/ZnO) composites in terms of PSC performance. In this ratio, both photoluminescence intensity in the UV region and the defect densities determined from electron paramagnetic resonance spectroscopy are low. Moreover, the specific capacitance of the best-performing GO/ZnO composites increased 2.7-fold and reached 6612 mFg(-1) after UV illumination. Besides, this device showed exceptional stability over 30,000 galvanostatic charge and discharge cycles with 99.6 % capacitance retention and 100 % Coulombic efficiency. The maximum energy density of 6.3 Whkg(-1) and power density of 625 Wkg(-1) were calculated for a 2.5 V operating voltage under UV illumination. As proof of concept, a digital watch was powered for more than 1 h and 40 min with GO/ZnO-based PSC charging under UV and AM1.5 sunlight illumination at 0.2 Ag-1 for 50 and 130 s, respectively.National Research Development and Innovation Plan [118C243]; TUBITAK [2020/38/E/ST5/00176]; National Science Centre of Poland from the SONATA BIS project; [PN 23 24 01 01]A.M.R., M.M. and M.D.L acknowledge the partial financial support from the Romanian Ministry of Research, Innovation and Digitalization, Nucleu Program within the National Research Development and Innovation Plan 2022-2027, project number PN 23 24 01 01.

Circulating miRNAs and their functional genetic variants in pseudoexfoliative glaucoma: potential of miR-146a-5p as a diagnostic biomarker
No full textPurposeThe etiology and pathogenesis of pseudoexfoliation syndrome (PEX) and its advancement into pseudoexfoliative glaucoma (PEG) are not fully understood. In this study, we aimed to evaluate the possible role played by two circulating microRNAs (miR-146a-5p and miR-196a-5p) in plasma and their functional genetic variants MIR146A rs2910164 and MIR196A2 rs11614913 in susceptibility to PEG or PEX.MethodsPlasma miRNA relative expression of 27 patients with PEG, 25 patients with PEX and 27 controls was determined using quantitative RT-PCR, and fold change was calculated using the 2(-; UDeltaUDelta;Ct) method. Genotyping of 300 patients with PEG, 300 patients with PEX, and 300 controls was performed using a PCR-restriction fragment length polymorphism analysis.ResultPlasma miR-146a-5p relative expression was significantly elevated in patients with PEG (3.9-fold) (P .000) and patients with PEX (2.7-fold) relative to controls (P = .001). The diagnostic ability of plasma miR-146a-5p expression fold change was good for discriminating PEG vs. controls (AUC = 0.897, P .000), and the optimal decision threshold was 1.83 (sensitivity = 74%, specificity = 93%). Plasma miR-196a-5p relative expression did not differ significantly between study groups. No significant difference in terms of the minor allele frequency or the distribution of genotypes for MIR146A rs2910164 G/C or MIR196A2 rs11614913 C/T was observed between study groups.ConclusionsCirculating miR-146a-5p can contribute to the risk of PEX/PEG. Therefore, we propose that plasma miR-146a-5p can be developed as a potential biomarker for the minimally invasive diagnoses of PEX/PEG and as a potential therapeutic target with further studies
Open Source Software Tools for Data Management and Deep Model Training Automation
No full text38th IEEE/ACM International Conference on Automated Software Engineering, ASE 2023 -- 11 September 2023 through 15 September 2023 -- 194295Designing and optimizing deep models require managing large datasets and conducting carefully designed controlled experiments that depend on large sets of hyper-parameters and problem dependent software/data configurations. These experiments are executed by training the model under observation with varying configurations. Since executing a typical training run can take days even on proven acceleration fabrics such as Graphics Processing Units (GPU), properly managing training data, avoiding human error in configuration preparations and securing the repeatability of the experiments are of utmost importance. In this paper, we present two open source software tools that aim to achieve these goals, namely, a Dataset Manager (DatumAid) tool and a Training Automation Manager (OrchesTrain) tool. DatumAid is a software tool that integrates with Computer Vision Annotation Tool (CVAT) to facilitate the management of annotated datasets. By adding additional functionality, DatumAid allows users to filter labeled data, manipulate datasets, and export datasets for training purposes. The tool adopts a simple code structure while providing flexibility to users through configuration files. OrchesTrain aims to automate model training process by facilitating rapid preparation and training of models in the desired style for the intended tasks. Users can seamlessly integrate their models prepared in the PyTorch library into the system and leverage the full capabilities of OrchesTrain. It enables the simultaneous or separate usage of Wandb, MLflow, and TensorBoard loggers. To ensure reproducibility of the conducted experiments, all configurations and codes are saved to the selected logger in an appropriate structure within a YAML file along with the serialized model files. Both software tools are publicly available on GitHub. © 2023 IEEE
