Case-Based Radiological Anatomy Instruction Using Cadaveric Mri Imaging and Delivered With Extended Reality Web Technology
No full textPurpose: Extended reality (XR) technology enhances learning in medical education. The purpose of this study was to develop and apply a case-based approach for teaching radiological anatomy utilizing XR technology for improved student exploration and engagement. Methods: The workflow consisted of MRI scanning cadavers followed by radiological, pathological, and anatomical assessment, and finally case presentation based on XR visualizations and student interaction. Case information (Subject, History, and Physical Exam) was presented to student groups who generated and recorded hypotheses using Google Forms. Results: Use of all components of the system was voluntary and a total of 74 students responded to the survey request (response rate = 95%). Assessment of the experience was conducted through a qualitative survey comprising four Likert scale questions (1-5, 1 lowest), three binary questions, and open-ended comments. Mean, standard deviation, and overall agreement (mean +/- SD, OA) showed that students found MRI scans of cadavers to be helpful for dissections (4.14 +/- 1.1, 74.3%) and provided an understanding of relevant anatomy (4.32 +/- 0.9, 79.7%), while 78.4% of students used the DICOM viewer to visualize scans of cadavers. The difficulty of use was found to be average (2.90 +/- 1.0, 23%). zSpace visualizations were used by 40.5% of students, generally agreeing that an understanding of spatial relationships improved as a result (3.60 +/- 1.0, 43.2%). More case-based sessions were favored by 97.3% of students. Conclusions: Results suggest that cadaveric MRI radiological visualization and XR technology enhance understanding of case-based anatomical dissections and encourage student exploration and engagement.The authors wish to thank the altruistic donors of the JABSOM, Willed Body Program for their generous contributions in providing unique educational and research opportunities for the next generation of health care providers.

Privacy Protection Via Joint Real and Reactive Load Shaping in Smart Grids
No full textFrequent metering of electricity consumption is crucial for demand-side management in smart grids. However, metered data can be processed fairly easily by employing well-established nonintrusive appliance load monitoring techniques to infer appliance usage, which reveals information about consumers' private lives. Existing load shaping techniques for privacy primarily focus only on altering metered real power, whereas smart meters collect reactive power consumption data as well for various purposes. This study addresses consumer privacy preservation via load shaping in a demand response scheme, considering both real and reactive power. We build a multi-objective optimization framework that enables us to characterize the interplay between privacy maximization, user cost minimization, and user discomfort minimization objectives. Our results reveal that minimizing information leakage due to a single component, e.g., real power, would suffer from overlooking information leakage due to the other component, e.g., reactive power, causing sub-optimal decisions. In fact, joint shaping of real and reactive power components results in the best possible privacy preservation performance, which leads to more than a twofold increase in privacy in terms of mutual information.

The Impact of Exporting on Women's Employment
No full textPurpose This paper aims to examine the effect of exports on women's employment rate for Turkish manufacturing firms over a recent period of 2003-2015. Design/methodology/approach The authors establish treatment models and use propensity score matching (PSM) techniques together with difference-in-difference methodology. Findings The results of the study indicate that starting to export increases women's employment rate for manufacturing firms. Gains in female employment rates are observed for the firms operating in low and medium low technology intensive sectors, low-wage sectors as well as laborlabor-intensive goods exporting sectors. Originality/value The authors complement previous literature by utilizing a rich harmonized firm-level dataset that covers a large number of firms and a recent time period. The authors distinguish between several sub-samples of firms according to technology intensity of the sector in which they operate, wage level and factor intensity of exports and investigate whether or not women gain from trade in terms of employment opportunities
Concept of Tectonics in Architectural Education
No full textThe creation of space in architecture can be explained in many ways and understandings. The ideational and practical creation or production of space, as the principal act or focus of architecture, is the result of a form of conception associated with the technological, cultural, social, philosophical or structural data contained in the relevant time. It can be said that researching expressions about the creation or production of space gains meaning depending on time, theoretical reading style and factors that affect architecture, such as technology or culture. This study sees the theoretical and practical expressions related to the creation of space can acquire different contents according to time and conditions, in the context of different factors, and the new readings to be made in current conditions that can produce new meanings as different conceptions of space as the source of its discussion. In this context, for example, investigating the effects of digital production and software technologies on the creation and production of space these days creates a research and discussion area in order to understand the attitudes of contemporary architecture towards the creation of space and to create a contemporary reading of space. This research, which can be generalized as the production of space and the questioning of the effect of current technologies on it, requires understanding different approaches and methods from the past in terms of the creation and production of space, considering the production of space before digital technologies. In addition, this study includes a discussion for the changes and transformations that have occurred or will occur in the spatial production of contemporary architecture, in the field of architectural tectonics, with the developing technology. Thus, it claims that classical and digital tectonic understandings have affordances for each other and understanding the affordances can enable the definition or comprehension of the new tectonic approach. In this framework, this study investigates James Gibson's concept of affordances as a theoretical basis. Afterwards, an experimental study in the field of education in the context of the results of this research is explained. This experimental study, which was created within the scope of Building Technologies MIM107 and MIM108 courses conducted at the first-year level of TOBB ETU Department of Architecture, provided the research and definition of the content of the new tectonic approach. This thesis depends on classical and digital tectonic understandings and concludes that hybrid tectonics, which emerged from them, as a theoretical research and experiment area, can create different and innovative approaches in all relevant areas of architectural theory and practice.Mimarlığın mekanını yaratması veya üretmesi farklı bir çok biçimde ve anlayışla açıklanabilir. Mekanın düşüncede ve pratik olarak yaratılmasının veya üretilmesinin, mimarlığın asal eylemi veya odağı olarak, ilgili zamanın barındırdığı teknolojik, kültürel, sosyal, felsefik veya yapısal verilerle ilişkili bir kavrama biçiminin sonucu olduğu; mekanın yaratılması veya üretilmesine yönelik ifadeleri araştırmanın da zamana, kuramsal okuma biçimine ve mimarlığa etki eden, örneğin teknoloji veya kültür gibi unsurlara bağlı olarak anlam kazandığı söylenebilir. Bu çalışma, mekanın yaratılmasına ilişkin kuramsal ve pratiğe yönelik ifadelerin, zamana ve koşullara göre, farklı etkenler bağlamında, farklı içerikler edinebileceği ve güncel koşullarda yapılacak yeni okumaların, farklı mekan kavrayışları olarak, yeni anlamlar üretebileceği tartışılmasını motivasyonunun kaynağı olarak görür. Bu bağlamda, örneğin bugünlerde, dijital üretim ve yazılım teknolojilerinin sağladığı olanakların mekanın yaratılması ve üretilmesine yaptığı etkinin araştırılması, güncel mimarlığın mekanın yaratılmasına yönelik tavırlarını anlamak ve bir mekan okuması oluşturmak için bir araştırma ve tartışma alanı doğurmuştur. Mekanın üretilmesi ve güncel teknolojilerin buna etkisinin sorgulanması olarak genellenebilecek bu araştırmanın mekanın yaratımı ve üretimi bakımından, dijital teknolojiler öncesi mekan üretimi göz önüne alındığında, geçmişten farklı anlayış ve yöntemleri kavramayı gerektirdiği iddia edilebilir. Böylece, mimarlık alanına etki eden teknoloji gibi bir faktörün ve de bundan önce mekanın yaratımı ve üretimine yönelik içeriğin, bugün güncel mimarlıkta mekansal üretimlerimizi düşünce ve pratik alanlarda nasıl etkilediği ve geçmişe göre neyin farklılaştığı üzerinden kuramsal bir tartışma yürütülmüştür. Bu çalışma, teknoloji ile birlikte güncel mimarlığın mekansal üretimlerinde, mimari tektonikler alanında, oluşan veya oluşacak değişim ve dönüşümleri tartışmaya açmıştır. Klasik ve dijital tektonik anlayışların günümüzde birbirlerine yönelik olanaklılıklarının olduğunu ve olanaklılıkların kavranmasının yeni tektonik anlayışın tanımlanması veya kavranmasını sağlayabileceğini iddia etmektedir. Bu çerçevede bu çalışma öncelikle James Gibson'ın olanaklılık kavramını kuramsal dayanak noktası haline getirmiş ve araştırmıştır. Sonrasında, bu araştırmanın sonuçları bağlamında eğitim alanında deneysel bir çalışma planlamıştır. TOBB ETÜ Mimarlık Bölümü 1. Sınıf düzeyinde yürütülen Yapı Teknolojileri MIM107 ve MIM108 dersleri kapsamında oluşturulan bu deneysel çalışma yeni tektonik anlayışın içeriğinin araştırılmasını ve tanımlanmasını sağlamıştır. Bu tez sonuçta klasik ve dijital tektonik anlayışlara bağlı olan; onlardan varlık bulan hibrit tektoniklerin kuramsal bir araştırma ve deney alanı olarak, mimari kuram ve pratiğin ilgili tüm alanlarında farklı ve yenilikçi yaklaşımları oluşturulabileceği sonucuna ulaşmıştır
Implementation and Evaluation of Age-Aware Downlink Scheduling Policies in Push-Based and Pull-Based Communication
No full textAs communication systems evolve to better cater to the needs of machine-type applications such as remote monitoring and networked control, advanced perspectives are required for the design of link layer protocols. The age of information (AoI) metric has firmly taken its place in the literature as a metric and tool to measure and control the data freshness demands of various applications. AoI measures the timeliness of transferred information from the point of view of the destination. In this study, we experimentally investigate AoI of multiple packet flows on a wireless multi-user link consisting of a transmitter (base station) and several receivers, implemented using software-defined radios (SDRs). We examine the performance of various scheduling policies under push-based and pull-based communication scenarios. For the push-based communication scenario, we implement age-aware scheduling policies from the literature and compare their performance with those of conventional scheduling methods. Then, we investigate the query age of information (QAoI) metric, an adaptation of the AoI concept for pull-based scenarios. We modify the former age-aware policies to propose variants that have a QAoI minimization objective. We share experimental results obtained in a simulation environment as well as on the SDR testbed.TUBITAK-BIDEB Grant [119C028]This work has been supported by TUBITAK-BIDEB Grant 119C028

Search for Resonant Pair Production of Higgs Bosons in the B(b)over-Barb(b)over Final State Using Pp Collisions at Root S=13 Tev With the Atlas Detector
No full textA search for resonant Higgs boson pair production in the b (b) over barb (b) over bar final state is presented. The analysis uses 126 fb(-1)- 139 fb(-1) of pp collision data at root s = 13 TeV collected with the ATLAS detector at the Large Hadron Collider. The analysis is divided into two channels, targeting Higgs boson decays which are reconstructed as pairs of small-radius jets or as individual large-radius jets. Spin-0 and spin2 benchmark signal models are considered, both of which correspond to resonant HH production via gluon-gluon fusion. The data are consistent with Standard Model predictions. Upper limits are set on the production cross section times branching ratio to Higgs boson pairs of a new resonance in the mass range from 251 GeV to 5 TeV.ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW, Austria; FWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq, Brazil; FAPESP, Brazil; NSERC, Canada; NRC, Canada; CFI, Canada; CERN; ANID, Chile; CAS, China; MOST, China; NSFC, China; Minciencias, Colombia; MEYS CR, Czech Republic; DNRF, Denmark; DNSRC, Denmark; IN2P3-CNRS, France; CEA-DRF/IRFU, France; SRNSFG, Georgia; BMBF, Germany; HGF, Germany; MPG, Germany; GSRI, Greece; RGC, China; Hong Kong SAR, China; ISF, Israel; Benoziyo Center, Israel; INFN, Italy; MEXT, Japan; JSPS, Japan; CNRST, Morocco; NWO, Netherlands; RCN, Norway; MEiN, Poland; FCT, Portugal; MNE/IFA, Romania; JINR; MES of Russia, Russian Federation; NRC KI, Russian Federation; MESTD, Serbia; MSSR, Slovakia; ARRS, Slovenia; MIZS, Slovenia; DSI/NRF, South Africa; MICINN, Spain; SRC, Sweden; Wallenberg Foundation, Sweden; SERI, Switzerland; SNSF, Switzerland; Canton of Bern, Switzerland; Canton of Geneva, Switzerland; MOST, Taiwan; TAEK, Turkey; STFC, United Kingdom; DOE, United States of America; NSF, United States of America; BCKDF, Canada; CANARIE, Canada; Compute Canada, Canada; CRC, Canada; COST, European Union; ERC, European Union; ERDF, European Union; Horizon 2020, European Union; Marie Sklodowska-Curie Actions, European Union; Investissements d'Avenir Labex, France; Investissements d'Avenir Idex, France; ANR, France; DFG, Germany; AvH Foundation, Germany; Herakleitos programme - EU-ESF, Greece; Thales programme - EU-ESF, Greece; Aristeia programme - EU-ESF, Greece; Greek NSRF, Greece; BSF-NSF, Israel; GIF, Israel; Norwegian Financial Mechanism 2014-2021, Norway; NCN, Poland; NAWA, Poland; La Caixa Banking Foundation, Spain; CERCA Programme Generalitat de Catalunya, Spain; Generalitat Valenciana, Spain; Gran Gustafssons Stiftelse, Sweden; Royal Society, United Kingdom; Leverhulme Trust, United KingdomWe thank CERN for the very successful operation of the LHC, as well as the support staff from our institutions without whom ATLAS could not be operated efficiently.We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW and FWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; 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 DNSRC, Denmark; IN2P3-CNRS and CEA-DRF/IRFU, France; SRNSFG, Georgia; BMBF, HGF and MPG, Germany; GSRI, Greece; RGC and Hong Kong SAR, China; ISF and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; NWO, Netherlands; RCN, Norway; MEiN, Poland; FCT, Portugal; MNE/IFA, Romania; JINR; MES of Russia and NRC KI, Russian Federation; MESTD, Serbia; MSSR, Slovakia; ARRS and MIZS, Slovenia; DSI/NRF, South Africa; MICINN, Spain; SRC and Wallenberg Foundation, Sweden; SERI, SNSF and Cantons of Bern and Geneva, Switzerland; MOST, Taiwan; TAEK, Turkey; STFC, United Kingdom; DOE and NSF, United States of America.
