description: This paper assesses the role of sovereign risk in explaining macroeconomic fluctuations in Turkey. We estimate two versions of a simple New Keynesian small open economy model on quarterly data for the period 1994Q3-2008Q2: A basic version and a version augmented by a default premium on government debt due to a perceived risk of sovereign debt default. Model comparisons clearly support the augmented version since it leads to stronger internal propagation and hence smaller shocks are required in order to reconcile the observed dynamics of nominal and real variables, leading to better forecasting performance. The estimated default probability is highly debt-elastic, indicating that default fears are a relevant concern. The results suggest that the augmented model may lead to a better understanding of macroeconomic fluctuations in emerging market economies that are subject to sovereign risk. In terms of policy implications, counterfactual experiments show that both more active monetary policy and stronger fiscal feedbacks from debt on taxes can lead to less volatile inflation and debt dynamics, but higher debt feedbacks on taxation additionally reduce expected default rates.

description: Microwave heating of a high-temperature plasma confined in a large-scale open magnetic trap, including all important wave effects like diffraction, absorption, dispersion and wave beam aberrations, is described for the first time within the first-principle technique based on consistent Maxwell's equations. With this purpose, the quasi-optical approach is generalized over weakly inhomogeneous gyrotrotropic media with resonant absorption and spatial dispersion, and a new form of the integral quasi-optical equation is proposed. An effective numerical technique for this equation's solution is developed and realized in a new code QOOT, which is verified with the simulations of realistic electron cyclotron heating scenarios at the Gas Dynamic Trap at the Budker Institute of Nuclear Physics (Novosibirsk, Russia).

description: For more than two decades, TRIZ specialists and developers of IT systems have been searching for efficient application of methodological tools in the field of software and hardware development. To date, there is a qualified understanding of when and how the use of TRIZ tools can be effective and fundamentally new. It often happens that such an application directly depends on the formulation of tasks at the business level in IT projects. In this paper, on the one hand, four approaches are identified that differ in the nature of interaction between TRIZ and IT systems, and on the other, business tasks are identified and under what conditions certain tools can be most in demand by the IT development community. The problems and potential of TRIZ application for each of the main information objects of IT systems are considered (Structures and diagrams, interfaces, platforms and systems, hardware architecture, process management\network traffic\big data, algorithms and semantics). Also, a study was conducted on the possibilities of methodological and instrumental integration with specialized technologies in IT systems, similar in their properties to a number of modern TRIZ tools (functional analysis of components and processes, flow analysis), so that their application in this area would be the most productive, would allow to develop and streamline the creative potential of teams developing modern software and hardware solutions and artificial intelligence systems. The article also provides examples and tasks for a better understanding of the specifics of objects and parameters by specialists from other industries. In the final part of the article, the importance of the considered issues is supported by the initiative of the organizing committee of the TRIZ Developers Summit to form research workgroups, in accordance with the previously identified four approaches of interaction between TRIZ and IT systems.

description: The thesis deals with phenomena of molecular diffusion in liquid environments. The examination of diffusing molecules provides information about the molecules themselves, and also about the structure of the surrounding media. This work deals with diffusion phenomena on length scales below 100 μm. The liquid phase consists of water or water/surfactant emulsions. The microstructures are fluidic channels etched in wafers of crystalline silicon. In these channels, diffusion-limited mixing at a liquid boundary is examined. These experiments took place in a stationary liquid flow. Environments on the nanoscale are made of binary liquids forming supramolecular orders by self-assembly. From these structures, the micellar and the lamellar structure are examined in particular. The focus is on the influence of cholesterol on the mobility of probe molecules in the lamellar phase. The main experimental method is Fluorescence Correlation Spectroscopy (FCS). Additionally, fundamentals for the tracking of single molecules are established by analyzing video recordings of fluorescing particles. The thesis provides advanced insight into the nature of molecular motion in nearly ideal systems. Further conclusions for investigations in natural environments, as they exist in eukaryotic cells, can be drawn from the experiments.

description: The notion of «strategy» is a key notion in management theory. Strategy is a kind of behavior style, which preconditions quite definite and relatively stable line of behavior of the object of strategy application at a fairly long historical interval. That’s why approaches and methods for strategy development, which are practically applicable, are so necessary and needed by the enterprises of any branch of industry and sphere of activity. Methods for strategic planning are known, which are based on system analysis and modeling of interaction between the analyzed object and external environment in time. The main disadvantage of these methods consists in the fact that they are not adapted to registering of quality changes in the analyzed system. In order to take into account, the fundamental changes in the system, it is proposed to use TRIZ tools in strategic planning, in particular, direct and reverse use of TRIZ Model. The method of strategic planning presupposes twofold approach: one way of planning implies the direction from solving the problems and resolving the contradictions within the system, while another way presupposes following the direction from ways of realization of the already formulated future image of the system under discussion. Both approaches mutually enrich each other in the iterative process of strategic planning. The article contains a review of existing methods of planning implying the identification of their strong and weak sides, comparison of these methods using a nine-screen model (system operator). The authors of this work describe the method and algorithm for forming strategic plans and quote practical examples for using this method and algorithm.

Investigating the Effectiveness of Semantic Tagging in Sense Disambiguation of Specialized Homographs from the perspective of F-Measure in Retrieving scientific texts
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2022

description: The aim of this study was to explain the application of text corpus tagging method in Sense disambiguation from specialized homographs and increasing the retrieval F-Measure of scientific texts containing such homographs.\nThis is an experimental study. Specialized homographs were identified by direct observation and morphological analysis of the word. The research sample consisted of 442 scientific articles of two groups of experimental group and control group. The control group had 221 full-text articles without tags and the experimental group had same 221 tagged articles, which were tested in the information retrieval system to measure the effectiveness of tagging in word sense disambiguation from specialized homographs.\nThe level of significance of the Wilcoxon signed-rank test showed that the F-Measure of retrieval results of specialized homographs after using the tagged specialized text corpus in the information retrieval system is significantly different than before. Examination of negative and positive rankings showed that the F-Measure of the results after using the tagged specialized text corpus has increased significantly and has reached its maximum level of 1.\nThe findings of the present study showed that there is not necessarily an inverse relationship between recall and precision, and the two can reach their maximum level of 1. The better efficiency of the retrieval system using this approach is due to the empowerment of the retrieval system in distinguishing between specialized homographs and identifying their semantic roles by using semantic tags as training data that were considered in the test and training set. Embedding the training set in the structure of the retrieval system provides additional information to serve the retrieval system to distinguish between the various meanings of specialized homographs. This tool is one of the elements that causes the optimal quality of retrieval and leads the information retrieval system from word-driven retrieval to content-driven retrieval when retrieving texts containing specialized homographs.

description: The anti-inflammatory effect of selagin-7-O-(6″-O-Acetyl-)-β-D-glucoside, isolated from the medicinal herb Cancrinia discoidea (Ledeb.) Poljak, was evaluated for its anti-inflammatory activity in the carrageenin- and serotonin-induced rat paw oedema models of acute inflammation and the cotton pellet-induced granuloma rat model of chronic inflammation. Flavone glycoside at doses of 5, 10, or 20 mg/kg, the clinical anti-inflammatory indo-methacin at 10 mg/kg, or vehicle were administered orally before injection of the pro-inflammatory compound. The test compound showed significant anti-inflammatory activity against paw edema induced by carrageenin or serotonin, most notably at the highest test dose of 20 mg/kg. In the cotton pellet-induced granuloma model, the compound showed dose-dependent anti-inflammatory activity, with the highest effect at 20 mg/kg. In all three assays, the flavone glucoside compound was more active at 20 mg/kg than indomethacin at 10 mg/kg.

Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2022

description: Context-aware systems serve the user by providing information that aligns with the preferences and context of the user. This study aims to recognize the contexts related to the entities of electronic theses and dissertations. Research is of the qualitative type that has used the documentary research method to find concepts, make coding, and classify contexts. The contribution of this research in increasing knowledge is to recognize the contexts of the users, electronic theses, and dissertation "ETD" and the system entities. The findings showed that the contexts of users are classified into 10 categories: user identity, interests and preferences, activities and history, social communication, computer context, user locations, user times, user access level, user status, and physical environment. The contexts of ETD have 8 categories: ETD identity, access level, audiences, activities and events, ETD content, time, place, and physical format of ETD. System contexts were grouped into 8 categories: system characteristics, user interaction capabilities, indexing capability, systems communication, user’s data storage, computing context, activity, and location. Conducting this research gives developers and decision-makers of ETD systems knowledge of contexts to redesign the system by considering the capabilities of context-aware systems to respond to users' needs, recommend documents, retrieve user-oriented documents, and develop system compatibility procedures. In the present study, we have tried to recognize all the contexts in an ETD system, and not only the user contexts but also the ETD contexts and the system contexts have been considered. context-aware ETD developers need some of the recognized contexts based on the type of context-aware services
Typology of the mentality of experts of government organizations in the field of establishing big data governance using Q methodology
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2022

description: In recent years, organizations in the public and private sectors have been faced with large volumes of structured and unstructured data that require a big data governance framework. Big data governance, by using environment monitoring and data collection, data storage and data analysis, provides the information needed by organizational decision makers. Establishing a big data governance framework enables organizations in the public and private sectors to make better decisions based on evidence and insight. Therefore, the purpose of this study is to investigate the mentality of experts in the field of establishing big data governance and for this purpose, Q methodology has been used. The statistical population of the present study included experts of government organizations and based on purposive sampling; 38 experts were selected for the study. In the present study, the discourse atmosphere included authentic domestic and foreign books and articles and semi-structured interviews. The number of propositions that were identified in the discourse atmosphere included 52 propositions, and by modifying and removing duplicate propositions, 48 final propositions were identified. Then, each of the Q propositions was numbered and the experts were asked to sort the number of each Q proposition in the Q diagram. Exploratory factor analysis and correlation matrix used to analyze the resulting data from the discourse atmosphere. Cronbach's alpha test, KMO index and Bartlett test used to evaluate the validity and reliability of the research method. The results of the present study showed three types of mentality that the total amount of variance explained was equal to 80.81%. The percentage of explained variance was 30.59% for the first type, 26.31% for the second type, and 23.90% for the third type. Evaluation of propositions related to the mentality of expert’s shows that most experts emphasize the results of establishing big data governance; They emphasize such things as facilitating knowledge flow, efficient and effective decision making, innovative performance, strengthening teamwork, and strategic planning and analysis. Experts, on the other hand, focus on drivers such as information technology, data control and oversight, structural mechanisms, democratization capacity, and legal capacity. In general, to take advantage of big data governance in public organizations and reduce the data gap, there must be coordination and consistency between the propositions and the results of establishing big data governance, and this research can serve as a stepping stone to this.
IoT Deployment Data Models in the Wheat Supply Chain Storage Section: Using an Action Design Research Approach
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2022

description: The supply chain for perishable products, especially agricultural goods, has always been one of the most important and challenging management issues at different times. Because, at all stages of the agricultural production process, unsafe and unsanitary factors may endanger the health of agricultural products. In addition, one of the key problems of the agricultural supply chain is the high volume of products wasted throughout the whole supply chain. For example, in Iran, as a developing country, about 30% of all agricultural products are wasted annually. The high volume of agricultural waste is especially important concerning wheat products as a political and strategic product. The results of some studies show that a large amount of wheat waste in developing countries is due to the widespread use of traditional methods in the storage process. Therefore, the application of emerging technologies such as the Internet of Things (IoT) can be an effective solution to this kind of problem. However, there are shortcomings in the IoT deployment in the supply chain, especially in the logistics sector, and researchers need to cover theoretical gaps in this area through modeling and optimization. Therefore, the present study intends to emphasize this important research issue for the first time in Iran using the Action Design Research approach. The most important findings of this research include the conceptual data model, the logical model of the database, and the physical data model for the IoT deployment in the storage section of the wheat supply chain, which has been designed and validated with the participation of industry and software engineering experts. The models designed in this research can be useful for the implementation of IoT technology in wheat storage centers and food factories. The findings of this study can provide a good guideline for officials and decision-makers to deploying IoT in the field of wheat storage.

Year: 2023

description: As a result of the pandemic, many companies consider digital transformation as the most important strategic direction of their development, which will help them maintain and develop their business in new conditions. At the same time, according to McKinsey, only 30% of companies successfully accomplish digital transformation of their businesses [1]. The complexity of digital transformation results from the fact that it affects almost all aspects of the company: the business model, product lines and services, customer segmentation, customer experience, operational processes, and technological solutions. In addition, there are many intangible factors, such as speed of adaptation, agility, innovation culture and leadership, which must not be neglected to succeed in digital transformation. During digital transformation, companies face multiple complex interrelated problems that need to be identified and addressed. Using TRIZ as one of problem-solving frameworks for digital transformation projects have been already discussed [2-4]. The papers usually consider the use of individual TRIZ tools for solving particular problems that arise during digital transformation. In this article we would like to investigate digital transformation from the point of view of the system evolution laws of TRIZ. Such analysis will allow us to develop a consistent view of digital transformation process as a stage of the system evolution, prioritize and reframe the arising problems in terms of evolution laws, provide recommendations on application of TRIZ tools. The ultimate goal of this study is to maximize the effect of using TRIZ framework in digital transformation process. We will also validate our conclusions with real cases from our practice.
Customer Value Analysis Based on WRFM Model With the Combined Data Mining Method(Case Study of Hygienic and Cosmetic Products)
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2022

description: The accumulated volume of customer information due to the growth and development of information technology and the creation of databases has led companies that want to provide better services to their customers to benefit from new tools for customer relationship. One of these tools and methods is data mining techniques that can play an important and key role in customer relationship management. The purpose of this study is to analyze customer value with a combined data mining approach based on the WRFM model.  So 64858 samples from customer database in the period 2019-2020 have been selected by available purposive sampling method. The weight of WRFM attributes has been determined by surveying 3 experts of the company using a hierarchical analysis process. Based on the initial variables of the research and the variables obtained from the attributes of the WRFM model, the purchase value of customers has been analyzed. SPSS Modeller and SPSS software were used to analyze the data.The results show that the K-Means clustering method has a better performance in customer segmentation than the TwoStep clustering and the Cohonen neural network methods. Finally, based on the criteria of purity percentage, repetition, error rate and Normalized Mutual Information (NMI (index, six clusters with NMI (0.631) were selected from different K-Means clustering.\nThis study introduces the WRFM model for customer value analysis.The weight of the attributes of this model is based on a survey of experts and using a hierarchical analysis process based on the degree of incompatibility (0.052) obtained from the hierarchical analysis method (0.15), (0.29) and (0.56), respectively, have been determined that these values ​​indicate the greater importance of the monetary value index than the other two indices; Finally, these six clusters were divided into 4 general categories using naming market segments methods in research (Chang and Tsai 2004; Babaian and Sarfarazi 2019): key and special customers, golden potential customers, missing uncertain customers and new uncertain customers. According to the research model, the company should focus more on its specific and key customers, ie customers who are in the first, third and fifth clusters, ie loyal customers who have higher than average values in the two attributes of monetary value and frequency and recently they have had purchases with a high value of Rials that the company should consider effective marketing strategies for this group of customers due to its limited resources in order to lead to more profitability for the company while maintaining customer relationship management.

Persian Causality Corpus (PerCause) and the Causality Detection Benchmark
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2022

description: Recognizing causal elements and causal relations in the text is among the challenging issues in natural language processing (NLP), specifically in low-resource languages such as Persian. In this research, we prepare a causality human-annotated corpus for the Persian language. This corpus consists of 4446 sentences and 5128 causal relations. Three labels of Cause, Effect, and Causal mark are specified to each relation, if possible. We used this corpus to train a system for detecting causal elements’ boundaries.\nAlso, we present a causality detection benchmark for three machine-learning methods and two deep learning systems based on this corpus. Performance evaluations indicate that our best total result is obtained through the CRF classifier, which provides an F-measure of 0.76. In addition, the best accuracy (91.4%) is obtained through the BiLSTM-CRF deep learning method

description: Numerical inversion is a general detector calibration technique that is independent of the underlying spectrum. This procedure is formalized and important statistical properties are presented, using high energy jets at the Large Hadron Collider as an example setting. In particular, numerical inversion is inherently biased and common approximations to the calibrated jet energy tend to over-estimate the resolution. Analytic approximations to the closure and calibrated resolutions are demonstrated to effectively predict the full forms under realistic conditions. Finally, extensions of numerical inversion are presented which can reduce the inherent biases. These methods will be increasingly important to consider with degraded resolution at low jet energies due to a much higher instantaneous luminosity in the near future.

description: Differential cross-sections for top-quark pair production, inclusively and in association with jets, are measured in $pp$ collisions at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC using an integrated luminosity of 140 fb$^{-1}$. The events are selected with one charged lepton (electron or muon) and at least four jets. The differential cross-sections are presented at particle level as functions of several jet observables, including angular correlations, jet transverse momenta and invariant masses of the jets in the final state, which characterise the kinematics and dynamics of the top-antitop system and the hard QCD radiation in the system with associated jets. The typical precision is 5%-15% for the absolute differential cross-sections and 2%-4% for the normalised differential cross-sections. Next-to-leading-order and next-to-next-to-leading-order QCD predictions are found to provide an adequate description of the rate and shape of the jet-angular observables. The description of the transverse momentum and invariant mass observables is improved when next-to-next-to-leading-order QCD corrections are included.

description: Low surface brightness (LSB) galaxies are dominated by dark matter halo from the innermost radii; hence they are ideal candidates to investigate the influence of dark matter on different dynamical aspects of spiral galaxies. Here, we study the effect of dark matter halo on grand-design, m = 2, spiral modes in a galactic disk, treated as a collisionless system, by carrying out a global modal analysis within the WKB approximation. First, we study a superthin, LSB galaxy UGC 7321 and show that it does not support discrete global spiral modes when modeled as a disk-alone system or as a disk plus dark matter system. Even a moderate increase in the stellar central surface density does not yield any global spiral modes. This naturally explains the observed lack of strong large-scale spiral structure in LSBs. An earlier work (Ghosh, Saini & Jog, 2016) where the galactic disk was treated as a fluid system for simplicity had shown that the dominant halo could not arrest global modes. We found that this difference arises due to the different dispersion relation used in the two cases and which plays a crucial role in the search for global spiral modes. Thus the correct treatment of stars as a collisionless system as done here results in the suppression of global spiral modes, in agreement with the observations. We performed a similar modal analysis for the Galaxy, and found that the dark matter halo has a negligible effect on large-scale spiral structure.

description: In this note, we aim to review algorithms for constructing crystal representations of quiver Yangians in detail. Quiver Yangians are believed to describe an action of the BPS algebra on BPS states in systems of D-branes wrapping toric Calabi-Yau three-folds. Crystal modules of these algebras originate from molten crystal models for Donaldson-Thomas invariants of respective three-folds. Despite the fact that this subject was originally at the crossroads of algebraic geometry with effective supersymmetric field theories, equivariant toric action simplifies applied calculations drastically. So the sole pre-requisite for this algorithm's implementation is linear algebra. It can be easily taught to a machine with the help of any symbolic calculation system. Moreover, these algorithms may be generalized to toroidal and elliptic algebras and exploited in various numerical experiments with those algebras. We illustrate the work of the algorithms in applications to simple cases of $\mathsf{Y}(\mathfrak{sl}_2)$, $\mathsf{Y}(\widehat{\mathfrak{gl}}_{1})$ and $\mathsf{Y}(\widehat{\mathfrak{gl}}_{1|1})$.

description: We test for galactic conformity at $0.23σ)$ one-halo conformity signal, or an excess of star-forming neighbors around star-forming central galaxies, of $\sim5$% on scales of 0-1 Mpc and a $2.5σ$ two-halo signal of $\sim1$% on scales of 1-3 Mpc. These signals are weaker than those detected in SDSS and are consistent with galactic conformity being the result of large-scale tidal fields and reflecting assembly bias. We also measure the star-forming fraction of central galaxies at fixed stellar mass as a function of large-scale environment and find that central galaxies are more likely to be quenched in overdense environments, independent of stellar mass. However, we find that environment does not affect the star formation efficiency of central galaxies, as long as they are forming stars. We test for redshift and stellar mass dependence of the conformity signal within our sample and show that large volumes and multiple fields are required at intermediate redshift to adequately account for cosmic variance.

description: The Chiral Magnetic Effect (CME) is a fundamental prediction of QCD, and various observables have been proposed in heavy ion collisions to access this physics. Recently the CMS Collaboration \cite{Khachatryan:2016got} has reported results from p+Pb collisions at 5.02 TeV on one such observable, the three-point correlator. The results are strikingly similar to those measured at the same particle multiplicity in Pb+Pb collisions, which have been attributed to the CME. This similarity, combined with two key assumptions about the magnetic field in p+Pb collisions, presents a major challenge to the CME picture. These two assumptions as stated in the CMS paper are (1) that the magnetic field in p+Pb collisions is smaller than that in Pb+Pb collisions and (2) that the magnetic field direction is uncorrelated with the flow angle. We test these two postulates in the Monte Carlo Glauber framework and find that the magnetic fields are not significantly smaller in central p+Pb collisions, however the magnetic field direction and the flow angle are indeed uncorrelated. The second finding alone gives strong evidence that the three-point correlator signal in Pb+Pb and p+Pb is not an indication of the CME. Similar measurements in d+Au over a range of energies accessible at RHIC would be elucidating. In the same calculational framework, we find that even in Pb+Pb collisions, where the magnetic field direction and the flow angle are correlated, there exist large inhomogeneities that are on the size scale of topological domains. These inhomogeneities need to be incorporated in any detailed CME calculation.

Measuring the relevance of retrieved images in search engines based on Persian language writing styles
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2022

description: The aim of this study was to investigate the image retrieval from selected search engines according to the written and semantic features of Persian language and determine their relevance using recall and precision formulas and to identify the most efficient search engine in retrieving images in Persian and by survey-analytical method. It was done using direct observation technique. After reviewing related researches, search keywords list was formed in the form of a checklist based on the written and semantic features of Persian language. Each of these keywords in the studied search engines, including two general search engines Google and Bing and Duckduckgo semantic search engine, which are among the most used search engines and have also provided the ability to search for images in Persian, search and the number of relevant and unrelated retrieved results were recorded. Then, the recall and precision of search results in each search engine were calculated and the relevance of images based on these features in each of the studied search engines was investigated. A variety of descriptive statistical techniques were applied to analyze the data along with Kolmogorov-Smirnov, Shapiro-Wilk, Kruskal-Wallis and Friedman tests. Findings demonstrated that Google, Bing and Duckduckgo search engines do not pay enough attention to the written and semantic features of Persian language and many of these features are ignored while searching and retrieving images. In the present study, Google search engine had a higher recall and precision than the other two search engines, and despite the claim of semantic search engines to provide better and more relevant information than other search engines, Duckduckgo search engine did not show good performance in retrieving images related to the written and semantic part of Persian language. There is also a significant difference between the recall and the precision of the three studied search engines.
Studying the users’ information-seeking behavior by recording brain waves activity with Electroencephalography method: A systematic Review
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2022

description: Despite the novelty in methodologies, User behavior study based on brain activity during information-seeking stages has become popular among information science researchers. This paper reviews scientific publications in which information-seeking behavior has been studied along with recorded brain activity to shed light on research status, challenges, and suggestions for future studies. Based on Kitchenham & Charters (2007) framework, a complete web search was performed in English and Persian scientific databases, and 22 publications in English were found as the final result, from 2007 to 2020. Review results demonstrate that exploring the user status (10 papers) and brain wave activity during information-seeking episodes (12 papers) were the most dominant subjective approaches in the field of user behavior studies. Cognitive load was found as an effective cognitive component on user status. With eye movement measurement and brain waves frequency study, 3 factors were found effective on cognitive load level generated during information searching and processing: searching media type, information representation, and text reading style. Brain wave activity and pupil dilation analysis were the most important measures in user status during search stages, and alpha and theta band waves were demonstrated as an index for cognitive load measurement during the information searching process. A correlation among eye data, search behavior, task complexity based on user experience, and cognitive style – as another effective factor on user status- led to results in different information searching behavior demonstrations. Also, 3 main stages were analyzed in the information-seeking process, based on brain wave activity: information exploring and query formulation, query reformulation and selection, relevance judgment, and decision making. Results showed a difference between brain activity areas, and differences in pupil dilation change level and alpha/beta frequency level during different search episodes. For future research, some suggestions were offered based on reviews. Finding relations between correlations among cognitive styles, task features, and domain knowledge during information searching process, personalized information retrieval improvement, more collaboration between information science and neurocognitive specialists, research in more user affective status like aggression and fatigue during the search process, using more economic methods and portable devices aiming to reduce research costs and expenses, facilitating larger sample studies and designing standard tasks were considered as a suggestion. Finally, some challenges were found based on reviewed studies. Some concepts like relevance feedback in information retrieval need more investigation. Also, it is necessary to investigate and explore user affections during the search process with multiple approaches.

description: The thermal-photon emission from strongly coupled gauge theories at finite temperature is calculated using holographic models for QCD in the Veneziano limit (V-QCD). The emission rates are then embedded in hydrodynamic simulations combined with prompt photons from hard scattering and the thermal photons from hadron gas to analyze the spectra and anisotropic flow of direct photons at RHIC and LHC. The results from different sources responsible for the thermal photons in QGP including the weakly coupled QGP (wQGP) from perturbative calculations, strongly coupled $\mathcal{N}=4$ super Yang-Mills (SYM) plasma (as a benchmark for reference), and Gubser's phenomenological holographic model are then compared. It is found that the direct-photon spectra are enhanced in the strongly coupled scenario compared with the ones in the wQGP, especially at high momenta. Moreover, both the elliptic flow and triangular flow of direct photons are amplified at high momenta for V-QCD and the SYM plasma. The results are further compared with experimental observations.
