Publisher Copyright: © 1991-2012 IEEE.This paper presents algorithms for the parallelization of inference in hidden Markov models (HMMs). In particular, we propose a parallel forward-backward type of filtering and smoothing algorithm as well as a parallel Viterbi-type maximum-a-posteriori (MAP) algorithm. We define associative elements and operators to pose these inference problems as all-prefix-sums computations and parallelize them using the parallel-scan algorithm. The advantage of the proposed algorithms is that they are computationally efficient in HMM inference problems with long time horizons. We empirically compare the performance of the proposed methods to classical methods on a highly parallel graphics processing unit (GPU).Peer reviewe
Tomorrow and Tomorrow and Tomorrow: Foreign Lands on Stolen Lands
No full textIn this moment of Palestinian liberation – a new future is in the making; un-walled and de-fenced. Inspired by Dr. Taylor Miller’s text, “A Pause, On Possibility,” I look to “Tomorrow.” This thesis imagines a possible world and architecture of a free Palestine – beyond western, colonized, pseudo-diplomatic fantasy, and into a pluriversal imagination that encompasses its freedom and radical re-imagination of bureaucracy. I propose the design of a Musafir Khana (a “Traveller’s Room”), on unceded and never-surrendered Algonquin land along the Kìchì Sìbì (Ottawa River), in so-called Ottawa, in so-called Canada. The project imagines futures beyond subject colonial realities. A wall, a fence, a gate – these are not only material obstacles, but also limits on the imaginations of fragile colonial minds. A wall, after all, will never touch the sky, nor the Earth's core. It is always limited by its own materiality and always circumvented by emancipatory imagination
Shear alignment of particles during spin coating
No full textSpin coating is a process for applying uniform coatings to a wide variety of substrates. The final film thickness depends on viscosity, drying rate, percentage of solids, and surface tension and many of these influencing factors have been investigated. Our recent research has been focused on alignment of anisotropic particles being deposited by spin coating. One key aspect of spin coating is the shear forces that are experienced by the fluid before solvent evaporation takes over and freezes in a final particle arrangement. We have calculated the shear experienced by the particles during all stages of the process and tracked the fluid flow to determine the individual particle trajectories. A small fraction of fluid that starts near the center of the wafer contributes to the final coating while the majority of the fluid is flung off. From our calculations and associated measurements, it is evident that the particles away from the center of the wafer are more aligned toward the flow direction due to the higher shearing effect they experienced. Less alignment of particles is found near the center of the wafer as shear is significantly lower at the center. Experimental investigation has been performed to verify the numerical results. Alignment of the particles in the final coating can be advantageous for various optical, electrical and magnetic applications.M.S.Includes bibliographical references (p. 49-50)
Mediapipe based Preprocessed VGGFace2 Dataset
No full textVGGFace2 Dataset and Face Mesh PreprocessingIntroductionThe VGGFace2 dataset is a large-scale face recognition dataset containing over 3.31 million images of 9,131 identities, with an average of 362 images per identity. The dataset is designed to include extensive variations in pose, age, illumination, ethnicity, and profession, making it one of the most diverse and challenging face recognition datasets available. For more details, please refer to the original publication:VGGFace2: A dataset for recognizing faces across pose and age - DOI: 10.48550/arXiv.1710.08092
Preprocessing Using MediaPipe 3D Face MeshOn this dataset, we applied the MediaPipe-based 3D face mesh algorithm to accurately detect faces while removing all background elements, including hair. Our preprocessing strictly retained facial landmarks, ensuring that only the essential facial features were preserved. This approach significantly enhanced the accuracy and generalization of our model, as the model was trained exclusively on landmark-based facial data.
Training and PerformanceThe preprocessed data was utilized to train Xception model, which resulted in remarkably accurate outcomes due to the strictly landmark-based facial representation. The model demonstrated robust performance including explainable-AI, proving that eliminating unnecessary background elements contributed positively to its efficiency and reliability.

Identifying and validating recurrent structural variants affecting tumor genomes using GROM and VN
No full textDo recurring structural variants in genomes of multiple myeloma patients affect tumorigenesis? We hypothesize that these structural variants play a part in tumorigenesis as they overlap certain genes that have functions related to cancer symptoms.Presented at the annual Celebration of Undergraduate Research and Creative Activity while the author was an undergraduate student at Rutgers University-Camden
Investigation of minimum fragment requirement for mimicking n-cadherin mediated adhesion
No full textCadherins are transmembrane glycoproteins that are involved in maintaining integrity of cell junctions, morphogenesis, cell sorting and many more important biological processes. In my thesis, I have focused on studying the binding affinity of a class of cadherin superfamily called N-cadherins. Prior studies have demonstrated that N-cadherins can promote neuronal growth and axonal regeneration in vitro. Moreover, there is a growing interest in development of small molecules targeting N-cadherins and designing of therapeutic agents to promote cell survival and axonal regeneration as well as inhibit cadherin mediated signaling. For in vitro studies, knowing the minimum fragments of adhesive binding domain i.e. extracellular domains that can recapitulate the wild type N-cadherin binding functions can help develop designing of biomaterials and platforms to study N-cadherin interactions. Two dimensional affinity measurements reveal probability of stable bond formation during homophilic and/or heterophilic interactions between cadherins via extracellular domains. In order to determine the minimum fragment of the extracellular domain required for binding to mimic full length cadherin and wild type cadherins expressed on cell surfaces, Micropipette Aspiration Assay (MPA) was performed. Using N-cadherin as a model for classical cadherins, the binding affinity of full length N-cadherin (N-cad EC1-5) expressed on a test cell surface (here, mesenchymal stem cell (MSCs) with the first two extracellular domains (N-cad EC1-2) and the binding pocket sequence HAVDI peptide and full length N-cadherin (N-cad EC 1-5) were measured by this assay. The first chapter of my thesis, I talked about the structural differences of most studied cadherins E and N-cadherins and briefly described the importance of the flanking amino acid of binding pocket sequence HAVDI in N-cadherins. In the following chapter, I describe the experimental approach for determining the binding affinities of N-cadherin fragments and compared the 2D binding affinity results with that of the full length wild type N-cadherin expressed on MSCs. Surprisingly, the results of the study revealed that there is no significantly difference in binding affinity between N-cad EC1-2 and N-cad EC1-5 as well as HAVDI and N-cad EC1-5. The MPA studies were conducted with both wild type MSCs expressing N-cad EC1-5 as well as RBCs modified with N-cad EC1-5. However, there is a lower binding affinity between E-cadherin and HAVDI than that between N-cadherin and HAVDI. These results demonstrate the importance of the flanking amino acids next to HAV sequence in cadherin specificity as well as the possible application of small peptide sequence HAVDI as a novel antagonist in processes involving N-cadherin mediated adhesion.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2020-12-01The student, Syeda Tajin Ahmed, accepted the attached license on 2018-12-10 at 21:09.The student, Syeda Tajin Ahmed, submitted this Thesis for approval on 2018-12-10 at 23:09.This Thesis was approved for publication on 2018-12-13 at 17:32.DSpace SAF Submission Ingestion Package generated from Vireo submission #13282 on 2019-02-07 at 14:23:22Made available in DSpace on 2019-02-07T20:44:28Z (GMT).

Are Status of Women and Contraceptive Prevalence Correlated in Pakistan?
No full textPakistan with an estimated population of around 142.5 million in mid 2001 is the seventh most populous country in the world and fourth in Asia and Pacific countries. The historical trends indicate a continuously increasing growth in population (Table 1). The population of the area now constituting Pakistan was 16.6 million in 1901. Since then the population has increased over eight-fold. Annual growth rates have risen from 1 percent in the first three decades of the century to around 2 percent in the next three decades and after peaking at little over 3 percent in the 1960s, has started showing a declining trend. Currently it is estimated that Pakistan’s population is growing at around 2.1 percent, still a very high rate of annual growth in population. Major contributing factor to the fast growth in population of Pakistan has been high fertility which has remained high for a very long period. It is evident that nearly 100 million population has been added to the population of Pakistan since 1961, that is, during the last four decades. Such rapid growth in population has several adverse implications for the socio-economic development of the country which has been offsetting the gains in social and economic development.
