Navigating a social world with robot partners: A quantitative cartography of the Uncanny Valley
Venue: Cognition
Year: 2016

Android robots are entering human social life. However, human robot interactions may be complicated by a hypothetical Uncanny Valley (UV) in which imperfect human likeness provokes dislike. Previous investigations using unnaturally blended images reported inconsistent UV effects. We demonstrate an UV in subjects' explicit ratings of likability for a large, objectively chosen sample of 80 real world robot faces and a complementary controlled set of edited faces. An "investment game" showed that the UV penetrated even more deeply to influence subjects' implicit decisions concerning robots' social trustworthiness, and that these fundamental social decisions depend on subtle cues of facial expression that are also used to judge humans. Preliminary evidence suggests category confusion may occur in the UV but does not mediate the likability effect. These findings suggest that while classic elements of human social psychology govern human robot social interaction, robust UV effects pose a formidable android specific problem.

Comprehensive Transcriptome Analysis Reveals Competing Endogenous RNA Networks During Avian Leukosis Virus, Subgroup J Induced Tumorigenesis in Chickens
Venue: Front. Physiol.
Year: 2018

Avian leukosis virus subgroup J (ALV J) is an avian oncogenic retrovirus that induces myeloid tumors and hemangiomas in chickens and causes severe economic losses with commercial layer chickens and meat type chickens. High throughput sequencing followed by quantitative real time polymerase chain reaction and bioinformatics analyses were performed to advance the understanding of regulatory networks associated with differentially expressed non coding RNAs and mRNAs that facilitate ALV J infection. We examined the expression of mRNAs, long non coding RNAs (lncRNAs) and miRNAs in the spleens of 20 week old chickens infected with ALV J and uninfected chickens. We found that 1723 mRNAs, 7,883 lncRNAs and 13 miRNAs in the spleen were differentially expressed between the uninfected and infected groups (P 0.05) Transcriptome analysis showed that, compared to mRNA, chicken lncRNAs shared relatively fewer exon numbers and shorter transcripts. Through competing endogenous RNA and co expression network analyses, we identified several tumor associated or immune related genes and lncRNAs. Along transcripts whose expression levels significantly decreased in both ALV J infected spleen and tumor tissues, BCL11B showed the greatest change. These results suggest that BCL11B may be mechanistically involved in tumorigenesis in chicken and neoplastic diseases, may be related to immune response, and potentially be novel biomarker for ALV J infection. Our results provide new insight into the pathology of ALV J infection and high quality transcriptome resource for in depth study of epigenetic influences on disease resistance and immune system.
Managing real time risks and returns: The Thomson Reuters NewsScope Event Indices
Year: 2012

As financial markets grow in size and complexity, risk management protocols must also evolve to address more challenging demands. One of the most difficult of these challenges is managing event risk, the risk posed by unanticipated news that causes major market moves over short time intervals. Often cited but rarely managed, event risk has been relegated to the domain of qualitative judgment and discretion because of its heterogeneity and velocity. In this chapter, we describe one initiative aimed at solving this problem. The Thomson Reuters NewsScope Event Indices Project is an integrated framework for incorporating real time news from the Thomson Reuters NewsScope subscription service into systematic investment and risk management protocols. The framework consists of a set of real time event indices each one taking on numerical values between 0 and 100 designed to capture the occurrence of unusual events of a particular kind. Each index is constructed by applying disciplined pattern recognition algorithms to real time news feeds, and validated using econometric methods applied to historical data. 3.
Methods for Evaluating Online, Resource based Learning Environments for Teachers
Year: 2006

Online delivery methods offer much promise for anytime, anywhere adult learning. As a method of outreach, and to provide support for just in time learning, teacher educators are increasingly deciding to design Web sites that are online, resource based learning environments for teachers and preservice teachers. Automated evaluation tools and data collection methods can help such Web site designers develop and use online, resource based learning environments to meet their goals of providing high quality learning opportunities for teachers. This article presents a three pronged approach for evaluating issues of pedagogical design and user centered functionality in online, resource based Web sites. Checklist, Web site traffic analysis, and talk aloud protocols art each described and then illustrated through their application to a site aimed at educating teachers about technology integration. We discuss the relevance for developing effective learning environments when teacher educators apply this evaluation approach to resource based learning environments.

Caffeic Acid layered Double Hydroxide Hybrid: A New Raw Material for Cosmetic Applications
Year: 2018

Bioactive ingredients from natural sources possess well known positive effects in cosmetic applications. Among them, phenolic acids have emerged with very interesting potential. Caffeic acid (CAF) is one of the most promising active compounds because it possess antioxidant, anti inflammatory, antitumoral and anti wrinkle effects. In order to increase its local bioavailability in topical applications, the vehiculation of caffeic acid can lead to a new raw material of cosmetic interest. For this purpose, clay minerals possess excellent properties, such as low or null toxicity and good biocompatibility. Clays are able to host a wide range of active ingredients in the interlayer region, using a green process known as intercalation reaction. The hosting of cosmetic actives into the layered structure of anionic clays allows the preparation of new materials with enhanced stability towards oxidation and photodegradation, better local bioavailability, and easier workability. In this paper, the successful vehiculation of caffeic acid into anionic clay is presented. The obtained hybrid is very promising for the cosmetic market because of its higher bioavailability and prolonged antioxidant activity.
Policy iteration based adaptive optimal control for uncertain continuous time linear systems with excitation signals
Venue: ICCAS 2010
Year: 2010

This paper proposes a novel policy iteration based adaptive optimal scheme for uncertain continuous time linear systems with excitation signals. The proposed method can solve the related linear quadratic optimal control problem in online fashion exactly and safely. In order to maintain persistence excitation condition, the controller injects the small excitation signals to the system. For this linear system with excitation signals, the policy iteration (PI) technique is investigated to adaptively find the optimal control law in the presence of both internal uncertainties and known excitation signals. For the proposed PI technique, the stability of the closed loop system and convergence to the optimal solution are mathematically proven. Numerical simulations are carried out to verify the effectiveness of the proposed method.
Review: Jo Reichertz (2013) Die Abduktion in der qualitativen Sozialforschung. Uber die Entdeckung des Neuen [Abduction in Qualitative Social Research. On the Discovery of the New]
Year: 2013

In this textbook, Jo REICHERTZ provides a competent insight into the concept of abduction. Proceeding from PEIRCE, especially his late works, the author analyzes all the key facets and relationships of this concept, paying particular attention to the delimitation of abduction against deduction and induction as the other, rigorous logical types of reasoning. The value of the second edition lies in its discussion of the aspects of naturalization and socialization in abduction, which is approached as intelligently as the rest of the book.

Impulse dispersion of aerosols during playing wind instruments
Venue: medRxiv
Year: 2021

Musical activities especially singing and playing wind instruments have been singled out as potentially high risk activities for transmission of SARS CoV 2, because of a higher rate of aerosol production and emission. Playing wind instruments can produce condensation water, droplets of saliva, and aerosol particles, which hover and convectional spread in the environmental air and can be potentially infectious. The aim of this study is to investigate the primary impulse dispersion of aerosols during playing different wind instruments in comparison to breathing and speaking. Nine professional musicians (3 trumpeters, 3 cross flutists and 3 clarinetists) of the Bavarian Symphony Orchestra performed the main theme of Ludwig van Beethoven' 9th symphony, 4th movement in different pitches and loudness. Thereby, the inhaled air volume was marked with small aerosol particles produced with a commercial e cigarette. The expelled aerosol cloud was recorded by cameras from different perspectives. Afterwards, the dimensions and dynamics of the aerosol cloud was measured by segmenting the video footage at every time point. Overall, the flutes produced the largest dispersion at the end of task of up to maximum distances of 1.88 m in front direction. Thereby it was observed an expulsion of aerosol in different directions: upwards and downwards at the mouthpiece, at the end of the instrument and along the flute at the key plane. In comparison, the maximum impulse dispersion generated by the trumpets and clarinets were lower in frontal and lateral direction (1.2 m and 1.0 m in front direction) The expulsion to the sides was also lower. Consequently, a distance of 3 m to the front and to the sides of 2 m for the flutes in an orchestral formation is proposed, for trumpets and clarinets a safety distance of 2 m to the front and 1.5 m between instrumentalists are recommendable.
Twin width I: tractable FO model checking
Venue: 2020 IEEE 61st Annual Symposium on Foundations of Computer Science (FOCS)
Year: 2020

Inspired by a width invariant defined on permutations by Guillemot and Marx [ we introduce the notion of twin width on graphs and on matrices. Proper minor closed classes, bounded rank width graphs, map graphs, $K_{t^ free unit $d$ dimensional ball graphs, posets with antichains of bounded size, and proper subclasses of dimension 2 posets all have bounded twin width. On all these classes (except map graphs without geometric embedding) we show how to compute in polynomial time a sequence of $d$ contractions, witness that the twin width is at most $d$ We show that FO model checking, that is deciding if a given first order formula \phi$ evaluates to true for a given binary structure $G$ on a domain $D$ is FPT in \vert \phi\vert$ on classes of bounded twin width, provided the witness is given. More precisely, being given a $d$ contraction sequence for $G$ our algorithm runs in time $f(d,\vert \phi\vert)\cdot\vert D\vert$ where $f$ is a computable but non elementary function. We also prove that bounded twin width is preserved by FO interpretations and transductions (allowing operations such as squaring or complementing a graph) This unifies and significantly extends the knowledge on fixed parameter tractability of FO model checking on non monotone classes, such as the FPT algorithm on bounded width posets by Gajarsky et al. [FOCS '15]
COMPARING ARTIFICIAL INTELLIGENCE MUSIC AND HUMAN MUSIC: A CASE STUDY OF PROF. DAVID COPE'S EMMY SYSTEM
Year: 2015

This is a pilot study analysing the difference between algorithmic compositions and human music, and subsequently evaluating the authenticity of music composing algorithms. In this project, we use tools from information theory to study the music pieces created by a well known system, "Emmy" built by Prof. David Cope. We make the comparison between Emmy's compositions in the style of J.S. Bach's chorales  and actual chorales pieces written by Bach  The main metric we use is the Shannon entropy (shortened as entropy in the paper) which measures the unpredictability of information content. We found that the overall entropy of Emmy's pieces are in general higher than the real Bach's pieces, indicating that the AI music are less predictable and are short of repeated notes. We also design the tool of entropy profile and the entropy window to examine the evolution of the entropy within the piece. It turns out that Emmy's pieces have higher and smoother pitch entropy profiles, relatively authentic duration entropy profile, which gives clues on how to improve the composition algorithm: reduce the introduction of new pitch patterns. Taking both the pitch and duration into consideration, Emmy's music have higher entropy profiles throughout, which confirms the observations and conclusions from the whole piece entropy perspective.
Gender mainstreaming in Sudan under climate change stresses: gaps and ways forward
Year: 2016

This study investigates the level of gender mainstreaming on planning and implementation of activities within number of governmental, nongovernmental and academic organizations in Sudan. Gender mainstreaming is the process of assessing the implications for women and men of any planned action including legislation policies or programs in all areas and at all levels. Organizations included on this research are entities that mainly involved on natural resources management disciplines, humanitarian activities, and academia. The problem stated on this study stemmed on the fact that information on agriculture and natural resources management domain including farming, forests, range management, livestock production is not disaggregated by sex, while climate change stresses on natural resources and agriculture compounds the vulnerability of women in use and management of natural resources. The methodology used on this study was purposive sampling using semi structured interviews to elicit information from selected organizations within Khartoum City the capital of the Sudan. The study revealed that there is lack of knowledge on gender concepts and lack of skillful expertise within some of the studied organizations and thus gender mainstreaming is not fulfilled yet. It also showed that there are either no regulations or no commitment to regulations on gender policies within the studied organizations, therefore, gender policies on domain of agriculture and natural resources management are not formulated. The study concluded that establishment of gender research units within academic institutions is necessary. Those units can be platforms to source and develop knowledge about the role of gender in climate change adaptations, and they also can be linked to decision making processes within institutions involved in natural resources and agriculture, where gender policies, could be developed and applied. Improved policy for natural resources management and agriculture had been suggested to reduce climate stresses on natural resources and agriculture.
Energy Efficient Multi Hop Device to Device Communications with Adaptive Forwarding Strategy
Venue: GLOBECOM 2017 2017 IEEE Global Communications Conference
Year: 2017

Device to device (D2D) communications in cellular networks facilitate direct transmissions between user equipment (UEs) In the case that direct transmission is not favourable due to long distances or poor channel conditions between the source UE (SUE) and the destination UE (DUE) multi hop D2D communications can be deployed, where relay UEs (RUEs) forward the data received from SUE to the DUE. In this paper, we propose an adaptive forwarding strategy for multi hop D2D communications to optimally choose between the best relay forwarding (BRF) mode and the cooperative relays beamforming (CRB) mode with the optimal number of RUEs, depending on which of them provides the higher instantaneous energy efficiency (EE) We analyse the associated average EE taking into account the circuit power consumption and the overhead for obtaining channel state information (CSI) forwarding mode selection and cooperative beamforming. In order to reduce the overhead for mode selection, we propose a distributed adaptive forwarding mode selection strategy. Simulation results reveal that multi hop D2D communications utilizing the proposed adaptive forwarding strategy achieves significantly higher EE than the BRF, CRB with the optimal number of RUEs, direct D2D communications, and conventional cellular communications.
Revolutions Without Revolutionaries? Social Media Networks and Regime Response in Egypt
Year: 2010

Does the Internet change the balance of power between authoritarian regimes and their domestic opponents? The results of this case study of Egyptian digital activism suggest that the Internet has important effects on authoritarian politics, though not necessarily the kind we have come to expect from popular accounts of online activism. In this dissertation, I argue that what I call Social Media Networks can trigger informational cascades through their interaction effects with independent media outlets and on the ground organizers. They do so primarily through the reduction of certain costs of collective action, the transmission capabilities of certain elite nodes in social and online networks, and through changing the diffusion dynamics of information across social networks. An important secondary argument is that while states, including Egypt, have become more adept at surveillance and filtering of online activities, SMNs make it impossible for authoritarian countries to control their media environments in the way that such regimes have typically done so in the past. Case studies of media events in Egypt between 2006 and 2008 explain how SMNs undermine the process of authoritarian media control and why the independent press is critical for claims making and the building of shared meaning. However, the power of SMNs is not capable of challenging the entrenched repressive capacity of determined states, nor can SMNs be substituted for the difficult work of grassroots organizing. I arrive at this conclusion through a case study of the April 6th Youth Movement, which staged nearly identical strikes on April 6th, 2008, and April 6th, 2009, with divergent results. Therefore, the dissertation concludes that even though SMNs may lead to richer information environments with increased capacity for organizing, the technologies themselves are not determinative of political outcomes. Finally, by studying the use of digital tools by Muslim Brothers and Baha'is, the dissertation argues that SMNs can provide critical public space and create discursive focal points for political and religious minorities.

Hyperbolic Heterogeneous Information Network Embedding
Venue: AAAI
Year: 2019

Heterogeneous information network (HIN) embedding, aiming to project HIN into a low dimensional space, has attracted considerable research attention. Most of the exiting HIN embedding methods focus on preserving the inherent network structure and semantic correlations in Euclidean spaces. However, one fundamental problem is that whether the Euclidean spaces are the appropriate or intrinsic isometric spaces of HIN? Recent researches argue that the complex network may have the hyperbolic geometry underneath, because the underlying hyperbolic geometry can naturally reflect some properties of complex network, e.g. hierarchical and power law structure. In this paper, we make the first effort toward HIN embedding in hyperbolic spaces. We analyze the structures of two real world HINs and discover some properties, e.g. the power law distribution, also exist in HIN. Therefore, we propose a novel hyperbolic heterogeneous information network embedding model. Specifically, to capture the structure and semantic relations between nodes, we employ the meta path guided random walk to sample the sequences for each node. Then we exploit the distance in hyperbolic spaces as the proximity measurement. The hyperbolic distance is able to meet the triangle inequality and well preserve the transitivity in HIN. Our model enables the nodes and their neighborhoods have small hyperbolic distances. We further derive the effective optimization strategy to update the hyperbolic embeddings iteratively. The experimental results, in comparison with the state of the art, demonstrate that our proposed model not only has superior performance on network reconstruction and link prediction tasks but also shows its ability of capture hierarchy structure in HIN via visualization.
