Where did Words Come from? A Linking Theory of Sound Symbolism and Natural Language Evolution
Year: 2008

Where did words come from? The traditional view is that the relation between the sound of a word and its meaning is arbitrary. An alternative hypothesis, known as sound symbolism, holds that form meaning correspondence is systematic. Numerous examples of sound symbolism exist across natural language phyla. Moreover, cross linguistic similarities suggest that sound symbolism represents a language universal. For example, many unrelated languages affix an "ee" sound to words in order to emphasize size distinctions or express affection (e.g. look at the teeny weeny baby) other such phonetic universals are evident for object mass, color, brightness, and aggression. We hypothesize that sound symbolism reflects sensitivity to an ecological law (i.e. Hooke's Law) governing an inverse relation between object mass and acoustic resonance. In two experiments healthy adults showed high agreement in matching pure tones to color swatches and nonwords to novel objects as linear functions of frequency and luminance. These results support a degree of non arbitrariness in integrating visual and auditory information. We discuss implications for sound symbolism as a factor underlying language evolution.
Service Hyperlink: Modeling and Reusing Partial Process Knowledge by Mining Event Dependencies among Sensor Data Services
Venue: 2017 IEEE International Conference on Web Services (ICWS)
Year: 2017

In an IoT environment, process analysis becomes more difficult as a process usually spans over a set of autonomous and distributed sensors. This paper consummates our previous service hyperlink model, to encapsulate dependencies among events generated from services. To effectively discover service hyperlinks, we transform the service hyperlink discovery problem into a frequent sequence mining problem. Existing frequent sequence mining algorithms cannot be directly used because they do not take the temporal constraints in event dependencies into consideration. Based on the dataset from a real power plant as well as several synthetic datasets, we do lots of experiments to verify the effectiveness and efficiency of our algorithm.
Identification of novel genes associated with a poor prognosis in pancreatic ductal adenocarcinoma via a bioinformatics analysis
Venue: Bioscience reports
Year: 2019

Pancreatic ductal adenocarcinoma (PDAC) is a class of the commonest malignant carcinomas. The present study aimed to elucidate the potential biomarker and prognostic targets in PDAC. The array data of GSE41368, GSE43795, GSE55643, and GSE41369 were downloaded from Gene Expression Omnibus (GEO) database. The differentially expressed genes (DEGs) and differentially expressed microRNAs (DEmiRNAs) in PDAC were obtained by using GEO2R, and overlapped DEGs were acquired with Venn Diagrams. Functional enrichment analysis of overlapped DEGs and DEmiRNAs was conducted with Metascape and FunRich, respectively. The protein protein interaction (PPI) network of overlapped DEGs was constructed by STRING and visualized with Cytoscape. Overall survival (OS) of DEmiRNAs and hub genes were investigated by Kaplan Meier (KM) plotter (KM plotter) Transcriptional data and correlation analyses among hub genes were verified through GEPIA and Human Protein Atlas (HPA) Additionally, miRNA targets were searched using miRTarBase, then miRNA DEG regulatory network was visualized with Cytoscape. A total of 32 DEmiRNAs and 150 overlapped DEGs were identified, and Metascape showed that DEGs were significantly enriched in cellular chemical homeostasis and pathways in cancer, while DEmiRNAs were mainly enriched in signal transduction and Glypican pathway. Moreover, seven hub genes with a high degree, namely, V myc avian myelocytomatosis viral oncogene homolog (MYC) solute carrier family 2 member 1 (SLC2A1) PKM, plasminogen activator, urokinase (PLAU) peroxisome proliferator activated receptor g (PPARG) MET proto oncogene, receptor tyrosine kinase (MET) and integrin subunit a 3 (ITGA3) were identified and found to be up regulated between PDAC and normal tissues. miR 135b, miR 221, miR 21, miR 27a, miR 199b 5p, miR 143, miR 196a, miR 655, miR 455 3p, miR 744 and hub genes predicted poor OS of PDAC. An integrative bioinformatics analysis identified several hub genes that may serve as potential biomarkers or targets for early diagnosis and precision target treatment of PDAC.
Joining of SS304 SS316 through novel microwave hybrid heating technique without filler material
Year: 2020

Microwaves are type of electromagnetic radiations with a wide range of wavelength varying from 1 m to 1 mm and frequency between 300 MHz and 300 GHz for different wavelengths. Rapid heat transfer takes place through microwaves and these waves can easily penetrate throughout the material leading to localized volumetric heating. Joining of materials through microwaves seen a rapid increase in current years over conventional methods because of its high diffusion rate, lower power consumption, lower defects and improved mechanical and physical properties; at the same time; this technology is non hazardous to the environment. In this work, microwave joining technique has been used to join stainless steel of different grades (SS304 and SS316) Experiments were carried out in 900 W and 2.45 GHz microwave oven. Specimens of cross section 6 x 5 mm2 were selected for butt joining purpose, completed by each half of SS304 and SS316. No filler powder was used during this joining process. Direct joining of stainless steel specimen SS304 and SS316 was done with the help of microwave hybrid heating technique. Charcoal powder was used as susceptor to accelerate the initial heating process. Optimum process time for joining of SS304 SS316 has been found by trial method, using constant gap of 10 s between successive trials. The joints have been characterized mechanically through micro hardness test. Physical characterization of joint was also performed through scanning electron microscopy and energy dispersive spectroscopy method. Results show that proposed method is able to develop joints with good mechanical and physical properties.
Learning Disentangled Multimodal Representations for the Fashion Domain
Venue: 2018 IEEE Winter Conference on Applications of Computer Vision (WACV)
Year: 2018

In many visual domains (like fashion, furniture, etc. the search for products on online platforms requires matching textual queries to image content. For example, the user provides a search query in natural language (e.g.,pink floral top) and the results obtained are of a different modality (e.g. the set of images of pink floral tops) Recent work on multimodal representation learning enables such cross modal matching by learning a common representation space for text and image. While such representations ensure that the n dimensional representation of pink floral top is very close to representation of corresponding images, they do not ensure that the first k1 n) dimensions correspond to color, the next k2 n) correspond to style and so on. In other words, they learn entangled representations where each dimension does not correspond to a specific attribute. We propose two simple variants which can learn disentangled common representations for the fashion domain wherein each dimension would correspond to a specific attribute (color, style, silhoutte, etc. Our proposed variants can be integrated with any existing multimodal representation learning method. We use a large fashion dataset of over 700K fashion items crawled from multiple fashion e commerce portals to evaluate the learned representations on four different applications from the fashion domain, namely, cross modal image retrieval, visual search, image tagging, and query expansion. Our experimental results show that the proposed variants lead to better performance for each of these applications while learning disentangled representations.
Moving beyond Borders: A History of Black Canadian and Caribbean Women in the Diaspora
Year: 2013

Moving Beyond Borders: A History of Black Canadian and Caribbean Women in the Diaspora By Karen Flynn (Toronto, Buffalo, London: University of Toronto Press, 2011) (301 pages, $60.00 cloth; $27.95 paper)Karen Flynn's study focuses on the lives of Caribbean and Canadian born Black professional women who were born between 1914 and the late 1940s. These women worked as nurses in Canada after training in hospital apprenticeship programs in Britain, the Caribbean, or Canada. The basis of her study, which is situated in nursing and labor history, rests on oral testimonies of 35 of these women; but the analysis is broadened by theoretical perspectives gleaned from postcolonialism, feminism, intersectionality, and diasporic Black studies. The book argues that Black women developed multiple subjectivities during their life course and underscores how these women "navigated the transition from childhood to adulthood" (p. 4) Their subjectivities and identities, first forged within the context of childhood, were then shaped and reshaped through migration, nursing education, and their different social roles as wives, single mothers, and community activists. The study highlights "the role of the interviewees as social actors in their own right" (p. 12).The author organizes the book along the life course paradigm the age graded life patterns that are influenced by trajectories of family and working life. A life course perspective "while attentive to social structures, allows us to see commonalities that the interviewees for this study share with women of other cultural and racial backgrounds" (p.5) We follow the life course of the interviewees through three interrelated frameworks of family, nation, and the political economy of work.Chapter 1 focuses on the primary socialization of the interviewees. The family "emerged as the central force for preparing the women to make the transition to adulthood" (p. 41) and it emerged as crucial to the formation of their psyches. Chapter 2 discusses the secondary socialization that took place in the school and the church. Flynn uses Althusser's concept of ideological state apparatuses, which constitutes subjects by interpellation to explain the influence of these institutions on the Black women's identities. According to Flynn, both institutions were imbricated in subjectivity and identity formation in ways that were both empowering and repressive. Schools provided an education and enabled friendships but contributed to how gendered selfhoods evolved and were characterized by racism. The church encouraged the young people to be competent individuals, although it also reinforced gendered hierarchies. Chapter 3 demonstrates that people do not migrate only for socioeconomic reasons. Instead, the interviewees provided multiple explanations for why they leftthe Caribbean. Flynn characterizes emigration as a luminal period in their lives: being separated from their families as young women caused much uncertainty but was also liberating.
The Return of the Sacred Stones of the Ovambo Kingdoms: Restitution and the Revision of the Past
Year: 2020

The discourse of restitution often takes place within the framework of the `ethics of collecting' with a focus on the return of objects obtained violently, but this has restricted the debate. The case study of the return of two sacred stones from Finland to Namibia reflects on the cultural impact of their return. Largely Christianised communities re encountered objects that were sacred and central to earlier belief systems. We argue that the role of the sacred stones changed over time, before they went into exile, in a way that challenges any assumption of stasis that might be assumed when deploying the concept of `tradition' The return of the two stones provoked renewed interest in pre Christian rituals, but also related to efforts to strengthen the position of `traditional authorities' in relation to the democratic system of governance in Namibia. The ripples of restitution illustrate the wider importance of the return of cultural artifacts to stimulating contemporary cultural and political debate.
?Se ha abierto el sistema politico colombiano? Una evaluacion de los procesos de cambio (1970 1998)
Year: 2009

A pesar de la continuidad democratica colombiana, existe una prolongada crisis de su sistema politico que se refleja en varias dimensiones. Esta crisis se ha atribuido tradicionalmente a los efectos que se derivan del <cierre> del sistema politico colombiano. A traves del analisis de las diferentes dimensiones del <cierre politico> indicando que tipo de implicaciones tiene cada una de ellas para el sistema y como han evolucionado, se trata de ver si los defectos del sistema politico que tradicionalmente se han atribuido a este <cierre> son en realidad causa exclusiva del mismo o bien pudieran deberse en parte a la apertura politica del sistema. El paso del cierre a la apertura politica tiene como consecuencia que durante un periodo de tiernpo relativamente prolongado los indicadores de convivencia y civilidad empeoren, este seria el caso de Colombia, donde en las ultimas decadas se han dado una serie de aperturas y cierres simultaneos, siendo esta tension entre cierre y apertura la que ha provocado avances, estancamientos y retrocesos democraticos simultaneos.  In spite of colombian democratic continuity, there is a extend crisis in its political system that reflects in several aspects. This crisis has been derived traditionally from <the closing> of the colombian political system. Through the analysis and evolutions of several aspects of <political closing> and its implies on the system, it is tried to proof if they are cause of the defects of the political system. The transit from the closing to the opening can deteriorate the indicators of coexistence and public spirit, there's the case of Colombia, where in the last decades the excessives openings and closings have simultaneous advances and breaking downs in the democracy.
Design and behavior of super long span cable stayed bridge with CFRP cables and UHPC members
Venue: Composites Part B: Engineering
Year: 2019

This paper proposes a cable stayed bridge with carbon fiber reinforced polymer (CFRP) cables and ultra high performance concrete (UHPC) members and presents its design and structural behavior to analyze its feasibility with a super long span. Based on the geometrical dimensions of a real cable stayed bridge with a steel girder and cables in addition to a normal concrete (NC) pylon and main span of 1088 m, a new counterpart cable stayed bridge using CFRP cables and a UHPC girder and pylon was designed. The dimensions of the UHPC girder were quantified by the section stiffness, punching resistance, local stability, and shearing resistance. The cross section sizes of the CFRP cables were determined by the principle of equivalent strength. The geometric and physical conditions of the UHPC pylon satisfied the principle of similarity theory. Using the finite element method, a comparative analysis of the mechanical behavior of two cable stayed bridge schemes was conducted, specifically regarding the static behavior, global stability, aerostatic stability, dynamic mode, and seismic performance. The results indicated that the detailed design and superior performance of the CFRP and UHPC made it practical to form a highly efficient and durable concrete cable stayed bridge system with CFRP cables and UHPC members. Moreover, these properties could enlarge the main span of a concrete cable stayed bridge to approximately 1000 m.

DNN Based Simultaneous Screen to Camera and Screen to Eye Communications
Venue: 2019 IEEE Global Communications Conference (GLOBECOM)
Year: 2019

Simultaneous screen to camera and screen to eye communications, i.e. watermarking, have been proposed in visible light communications. The main purpose of such communications is to provide many data bits for camera devices and visual information for human eyes by using a common displayed image. To this end, the existing studies leverage the capability discrepancy and distinctive features between the human vision system and camera devices. However, the existing techniques mainly require high refresh rates in both screen and camera devices to achieve better throughput while keeping high visual quality. In this paper, we propose a novel transmission scheme for efficient simultaneous screen to camera and screento eye communications without a need of high refresh rates. Specifically, we use deep convolutional neural networks (DCNN) based watermark encoder and decoder to embed many bits into high quality images, and then to maximize throughput from the bit embedded image. With end to end adversarial learning, the encoder networks learn a mapping function to embed digital data into an original image based on a perceptual loss function while the decoder networks also learn a mapping function from the bitembedded image to the data bits based on a cross entropy loss function. From the evaluations, we show that the proposed watermark encoding and decoding networks yield high throughput from the bit embedded images compared with a simple DCNNbased watermarking. In addition, the bit embedded images on the screen achieve high quality for human perception.
Effect of Emotion and Articulation of Speech on the Uncanny Valley in Virtual Characters
Venue: ACII
Year: 2011

This paper presents a study of how exaggerated facial expression in the lower face region affects perception of emotion and the Uncanny Valley phenomenon in realistic, human like, virtual characters. Characters communicated the six basic emotions, anger, disgust, fear, sadness and surprise with normal and exaggerated mouth movements. Measures were taken for perceived familiarity and human likeness. The results showed that: an increased intensity of articulation significantly reduced the uncanny for anger; yet increased perception of the uncanny for characters expressing happiness with an exaggeration of mouth movement. The practical implications of these findings are considered when controlling the uncanny in virtual characters.
Evaluating the Effect of Smart Parking Technology on Campus Parking System Efficiency using Discrete Event Simulation
Year: 2013

This study investigated the effect of smart parking systems (SPS) on parking search times (PST) in large parking lots. SPSs are systems that disseminate parking spot availability to drivers. The parking lot selected for data collection was a university parking lot with 234 spaces. The data collected included arrival rates, departure rates, the geometric properties of the parking lot, preferred parking search strategies, and driving speeds. Arena 13.9, by Rockwell Automation, Inc, was utilized as the modeling software. The base model was built from observed parking search strategies (PSS) of drivers. The model was validated using a t test for independent samples to compare the PSTs of the base model and actual parking lot. Once the base model was verified and validated, the logic was altered to reflect (PSS) (IV) with real time parking availability (i.e. simulating the presence of an SPS) The PSTs (DV) for the base and experimental models were compared using a t test for independent samples. It was found that SPSs reduce PSTs by an average of only 11 seconds over a 2 week period for a single lot SPS. However, this shows potential for a multi lot SPS that might save more time and harmful vehicle emissions.
