description: Compressed data aggregation (CDA) over wireless sensor networks (WSNs) is task-specific and subject to environmental changes. However, the existing compressed data aggregation (CDA) frameworks (e.g., compressed sensing-based data aggregation, deep learning(DL)-based data aggregation) do not possess the flexibility and adaptivity required to handle distinct sensing tasks and environmental changes. Additionally, they do not consider the performance of follow-up IoT data-driven deep learning (DL)-based applications. To address these shortcomings, we propose OrcoDCS, an IoT-Edge orchestrated online deep compressed sensing framework that offers high flexibility and adaptability to distinct IoT device groups and their sensing tasks, as well as high performance for follow-up applications. The novelty of our work is the design and deployment of IoT-Edge orchestrated online training framework over WSNs by leveraging an specially-designed asymmetric autoencoder, which can largely reduce the encoding overhead and improve the reconstruction performance and robustness. We show analytically and empirically that OrcoDCS outperforms the state-of-the-art DCDA on training time, significantly improves flexibility and adaptability when distinct reconstruction tasks are given, and achieves higher performance for follow-up applications.

Poly (Amido Amine) Dendrimers: Role of Architectural Features on Biodistribution and Oral Absorption Enhancement
Creators: name: Sadekar, Shraddha Shirish
Publisher: name: University of Utah
Year: 2014

description: Most of the chemotherapeutics used in the clinic indiscriminately act on healthy proliferating cells along with malignant cells resulting in nonspecific toxicities, a narrow therapeutic index and reduced patient quality of life. Most of such agents are also limited by very low aqueous solubility. One strategy to overcome these challenges is to use biocompatible, water-soluble polymeric carriers to deliver chemotherapeutics with higher selectivity to sites of action (tumors), resulting in a better safety profile, increased maximum tolerated dose, and potentially better efficacy. Poly(amido amine) or PAMAM dendrimers are a class of branched polymers being extensively investigated for their potential as carriers for the delivery of anticancer agents. Their commercial availability, well-defined physicochemical and architectural features, ease of surface functionalization and encapsulation make PAMAM dendrimers useful for the delivery of chemotherapeutics. This dissertation focusses on two aspects of PAMAM dendrimers as drug carriers. The influence of PAMAM's molecular architecture on biodistribution and pharmacokinetics is compared with traditionally used and clinically investigated linear polymers at various molecular weights. Architecture of the polymer affected its hydrodynamic size at different molecular weights. A difference in accumulation of polymers of varying architecture in nonspecific elimination organs (kidney, liver) as well as site-specific organs (tumor) was observed. Variation in polymer architecture also resulted in a decrease in blood clearance with increase in hydrodynamic size and affinity to passively target the tumor by the enhanced permeability and retention effect when circulating in the blood. This dissertation also explored the use of PAMAM dendrimers for oral delivery of chemotherapeutics. By virtue of their unique three-dimensional architecture, PAMAM dendrimers are known to encapsulate, complex and solubilize hydrophobic drugs, modify epithelial tight junctions and act as drug carriers for oral delivery. It was observed that co-administration with dendrimers increased oral bioavailability of camptothecin, a schedule-dependent drug limited in oral use by low and variable absorption. Results suggest that this increase in absorption was not due to epithelial tight junction modulation and that drug inclusion in PAMAM interior controlled solubilization in gastric conditions and increased oral bioavailability.

Immunology of allosensitization observed with left ventricular assist device implantation: can newly developed methods define precise antibody specificities?

description: Patients implanted with left ventricular assist devices (LVAD) often develop lymphocyte reactive antibodies (allosensitization) leading to prolonged waiting time and possible poor transplant outcome.  The question is: are these antibodies specifically directed against HLA class I antigens and what may be causing their induction?  This thesis is intended to define more precisely the specificity of the lymphocyte reactive antibodies and to evaluate newly developed methods to define allosensitization. Sera from sensitized LVAD recipients studied for autoimmune antibodies and underwent a series of differential cellular adsorptions and elutions.  Sera (unabsorbed and absorbed) and eluates were assayed in parallel using newly developed methods to define antibody specificities.  Fifteen patients were studied in this investigation.  Antiphospholipid antibodies were detected in seven of seven patients tested, but only four of the seven remained positive as HLA specific antibodies became apparent.  No patients tested positive for autoantibodies against antinuclear antigens.  No auto- or cross-reactivity to pig lylmphocytes was found by differential cellular absorptions, and the thermal optima of antibody binding were consistent with alloreactivity.  Sera from eight patients absorbed with pooled platelets had a 78% reduction in reactivity to class I HLA antigens.  Preliminary specificity assignments were confirmed in six of eight patients as a result of absorption using homozygous B-cells.  Using a newly developed single HLA class I antigen flow method, HLA specificity was determined in seven of seven patients previously reported as multispecific.  Blocking studies confirmed HLA class I specificity in six of six patients.  Only three of twelve patients tested positive for proinflammatory or immune-stimulating cytokines.  This investigation demonstrates that a majority of sensitized LVAD recipients have IgG antibodies that are optimally active at room temperature and 37°C, have high avidity, and show HLA specificity in the absence of auto- and cross-reactivity.  Also the use of singly HLA antigen coupled heads to test high panel reactive antibody (PRA) sera showed the precise information about antibody specificity could be obtained.  Blood transfusion, chronic infection, and the LVAD itself are the most likely the causes of allosensitization.

title:  Diritto privato e funzione economico-sociale: radici bettiane d’una formula
Creators: name: Miletti, Marco Nicola
Publisher: name: Roma TrE-Press
Year: 2017

description: La formula funzione economico-sociale è ricorrente nelle pagine civilistiche di Emilio Betti. Essa esprime l’aspirazione ad un diritto privato in grado di affrancarsi dall’individualismo liberale e di recepire, soprattutto nella sfera delle obbligazioni e dei contratti, le istanze di cooperazione e di solidarietà maturate nella «coscienza sociale». Nella riflessione dello studioso camerte, tuttavia, il negozio giuridico da un lato rappresentava lo strumento di ‘spontanea’ auto-regolamentazione di rapporti pre-giuridici, dall’altro sottostava al vaglio di conformità effettuato dall’ordinamento, al quale spettava valutare la coerenza tra tipi negoziali creati dai privati e finalità perseguite dai pubblici poteri. Quest’ultima convinzione emerge nettamente nel contributo dell’insigne giurista alla codificazione civile del 1942 e imprime all’accezione bettiana di funzione una curvatura conservatrice o comunque dirigistica.

description: In this work, we propose that Majorana zero modes can be realized at the corners of the two-dimensional unconventional insulator. We demonstrate that 1T-PtSe2 is a symmetry indicator-free (SI-free) unconventional insulator, originating from orbital hybridization between Pt $d$ and Se $p_{x,y}$ states. The kind of SI-free unconventionality has no symmetry eigenvalue indication. Instead, it is diagnosed directly by the Wannier charge centers by using the one-dimensional Wilson loop method. The obstructed edge states exhibit strong anisotropy and large Rashba splitting. By introducing superconducting proximity and an external magnetic field, the Majorana corner modes can be obtained in the 1T-PtSe2 monolayer. In the end, we construct a two-Bernevig-Hughes-Zhang model with anisotropy to capture the Majorana physics.

Studies of poliovirus replication.

description: Poliovirus RNA synthesis in vitro was studied in an attempt to determine the conditions required for accurate product synthesis. Analysis of in vitro reaction products by gel electrophoresis, sucrose gradient sedimentation, hybridization and RNase T(,1) oligonucleotide fingerprints revealed that crude cytoplasmic extracts synthesize products which are identical to those made in infected cells; whereas, detergent-extracted complexes fail to synthesize full-length single-stranded RNA. Both complexes synthesize predominantly plus-stranded RNA, and detergent treatment inhibits synthesis of full-length single-stranded RNA by complexes which, untreated, are capable of making this product. The results suggest that poliovirus replication complexes consist of a detergent-resistant core complex which elongates nascent chains on predominantly double-stranded templates, and a detergent-sensitive factor which permits completion and release of full-length single-stranded RNA. RNase T(,1) oligonucleotide fingerprints of in vitro products revealed that detergent-extracted complexes fail to replicate a specific internal region of the RNA, suggesting that detergent interferes with a function involved in conformational aspects of replication. A short-lived replication complex protein, 4a, was identified which is associated with the detergent-extracted complex. Tryptic peptide analysis, pulse-chase data and the effects of inhibitors of proteolytic enzymes suggest that 4a may be a precursor to the protein associated with RNA elongation activity, 4b. Since VPg may be a primer for RNA synthesis and appears to be derived from a precursor protein, 4a may contain the sequences for both VPg and 4b. Thus, 4a may be involved in initiation of RNA synthesis. This possibility prompted an analysis of initiation by replication complexes in vitro. Crude cytoplasmic extracts were demonstrated to be capable of utilizing an exogenous RNA template to synthesize minus-strand RNA, which was detected among double-stranded products by RNase T(,1) fingerprints. For comparative purposes, a fingerprint of poliovirus minus-strand RNA from infected cells was prepared. This approach may be useful in the development of an in vitro assay which will permit further analysis of possible initiation activity by the replication complex-associated protein, 4a.

description: Despite effective treatment being available since the 1940s, tuberculosis (TB) remains a leading cause of death by a single infectious agent. Continued transmission is one of the driving factors of the TB epidemic. In high TB and HIV prevalent settings Mycobacterium tuberculosis transmission dynamics are still poorly understood. Throughout adolescence, individuals have increasing social contacts with the wider community. Thus, understanding M. tuberculosis infection among adolescents has potential for understanding M. tuberculosis infection in the population. This thesis reports findings from a cross-sectional study among adolescents in a high TB and HIV prevalence setting. A sample of adolescents (aged 10-19 years) resident in the southern part of the Africa Health Research Institute(AHRI) demographic surveillance area (DSA) was enrolled from their homes. Blood samples were obtained, and M. tuberculosis infection was measured using the QuantiFERON-TB Gold-plus assay. A total, 1,094 adolescents were enrolled, and the prevalence of M. tuberculosis infection was 22.8% (95% confidence interval [CI]: 20.4-25.3%). Older age, history of lifetime household TB contact and living in communities with high HIV prevalence were associated with increased odds of M. tuberculosis infection. There was no evidence of association between M. tuberculosis infection and Bacillus Calmette-Guérin (BCG) vaccination, household socioeconomic status, and increased cumulative monthly contact hours with either adult males or females. The spatial distribution of M. tuberculosis infection showed geographical variation. Communities with increased M. tuberculosis infection prevalence were observed on the south eastern part of the study area where population density and HIV prevalence are higher than other parts of the study area. The findings in this research show that household contacts of individuals with TB disease and individuals from communities with high HIV prevalence remain at risk of infection and should be prioritised for TB prevention and care activities.

description: The complex background in the soil image collected in the field natural environment will affect the subsequent soil image recognition based on machine vision. Segmenting the soil center area from the soil image can eliminate the influence of the complex background, which is an important preprocessing work for subsequent soil image recognition. For the first time, the deep learning method was applied to soil image segmentation, and the Mask R-CNN model was selected to complete the positioning and segmentation of soil images. Construct a soil image dataset based on the collected soil images, use the EISeg annotation tool to mark the soil area as soil, and save the annotation information; train the Mask R-CNN soil image instance segmentation model. The trained model can obtain accurate segmentation results for soil images, and can show good performance on soil images collected in different environments; the trained instance segmentation model has a loss value of 0.1999 in the training set, and the mAP of the validation set segmentation (IoU=0.5) is 0.8804, and it takes only 0.06s to complete image segmentation based on GPU acceleration, which can meet the real-time segmentation and detection of soil images in the field under natural conditions.

Modeling and analysis of longitudinal multimodal magnetic resonance imaging: application to early brain development
Creators: name: Sadeghi, Neda
Publisher: name: University of Utah
Year: 2014

description: Many mental illnesses are thought to have their origins in early stages of development, encouraging increased research efforts related to early neurodevelopment. Magnetic resonance imaging (MRI) has provided us with an unprecedented view of the brain in vivo. More recently, diffusion tensor imaging (DTI/DT-MRI), a magnetic resonance imaging technique, has enabled the characterization of the microstrucutral organization of tissue in vivo. As the brain develops, the water content in the brain decreases while protein and fat content increases due to processes such as myelination and axonal organization. Changes of signal intensity in structural MRI and diffusion parameters of DTI reflect these underlying biological changes. Longitudinal neuroimaging studies provide a unique opportunity for understanding brain maturation by taking repeated scans over a time course within individuals. Despite the availability of detailed images of the brain, there has been little progress in accurate modeling of brain development or creating predictive models of structure that could help identify early signs of illness. We have developed methodologies for the nonlinear parametric modeling of longitudinal structural MRI and DTI changes over the neurodevelopmental period to address this gap. This research provides a normative model of early brain growth trajectory as is represented in structural MRI and DTI data, which will be crucial to understanding the timing and potential mechanisms of atypical development. Growth trajectories are described via intuitive parameters related to delay, rate of growth, and expected asymptotic values, all descriptive measures that can answer clinical questions related to quantitative analysis of growth patterns. We demonstrate the potential of the framework on two clinical studies: healthy controls (singletons and twins) and children at risk of autism. Our framework is designed not only to provide qualitative comparisons, but also to give researchers and clinicians quantitative parameters and a statistical testing scheme. Moreover, the method includes modeling of growth trajectories of individuals, resulting in personalized profiles. The statistical framework also allows for prediction and prediction intervals for subject-specific growth trajectories, which will be crucial for efforts to improve diagnosis for individuals and personalized treatment.

description: Traditionally, stratospheric sudden warming events (SSWs) are defined using a fixed threshold criterion. This criterion, however, may lead to spurious results if the climate of the underlying dataset is changing. In an attempt to overcome this potential shortcoming we develop alternative criteria to define such events and test these criteria using reanalysis and climate model data. Results show that under different future climate forcing scenarios the annual and monthly mean SSW frequency increase. This increase is most robust in early to mid-winter. We therefore conclude that under a changing climate there is a higher potential for winter cold air outbreaks for regions such as North America, Europe, and northern Asia.

description: Nonequilibrium phases of quantum matter featuring time crystalline eigenstate order have been realized recently on noisy intermediate-scale quantum (NISQ) devices. While ideal quantum time crystals exhibit collective subharmonic oscillations and spatiotemporal long-range order persisting for infinite times, the decoherence time of current NISQ devices sets a natural limit to the survival of these phases, restricting their observation to a shallow quantum circuit. Here we propose a time-periodic scheme that leverages quantum-classical feedback protocols in subregions of the system to enhance a time crystal signal significantly exceeding the decoherence time of the device. As a case of study, we demonstrate the survival of the many-body localized discrete time crystal phase in the one-dimensional periodically kicked Ising model, accounting for decoherence of the system with an environment. Based on classical simulation of quantum circuit realizations we find that this approach is suitable for implementation on existing quantum hardware and presents a prospective path to simulate complex quantum many-body dynamics that transcend the low depth limit of current digital quantum computers.

Tropical geometry

description: Tropical geometry connects the fields of algebraic and polyhedral geometry. This connection has been used to discover much simpler proofs of fundamental theorems in algebraic geometry, including the Brill-Noether theorem. Tropical geometry has also found applications outside of pure mathematics, in areas as diverse as phylogenetic models and auction theory. This dissertation seeks to answer the question of when the minors of a symmetric matrix form a tropical basis. The first chapter introduces the relevant ideas and concepts from tropical geometry and tropical linear algebra. The second chapter introduces different notions of rank for symmetric tropical matrices. The third chapter is devoted to proving all the cases, outside symmetric tropical rank three, where the minors of a symmetric matrix form a tropical basis. The fourth chapter deals with symmetric tropical rank three. We prove that the 4 × 4 minors of an n×n symmetric matrix form a tropical basis if n ≤ 5, but not if n ≥ 13. The question for 5 < n < 13 remains open. The fifth chapter is devoted to when the minors of a symmetric matrix do not form a tropical basis. We prove the r × r minors of an n × n symmetric matrix do not form a tropical basis when 4 < r < n. We also prove that, when the minors of a matrix (general or symmetric) define a tropical variety and tropical prevariety that are different, then, with one exception, the two sets differ in dimension. The exception is the 4 × 4 minors of a symmetric matrix, where the question is still unresolved. The sixth chapter explores tropical conics. A correspondence between a property of the symmetric matrix of a quadric and the dual complex of that quadric is demonstrated for conics, and proposed for all quadrics. The seventh chapter reviews the results and proposes possible questions for further study. The first appendix is devoted to correcting a proof in a paper cited by this dissertation. The second appendix is a transcript of the Maple worksheets used to perform the computer calculations from the fifth chapter.

description: In tempi recenti la formula della ‘funzione sociale’ ha assunto contenuti meno generici e svolge effetti pratici che in passato non aveva. Ciò avviene per la moderna tendenza alla ‘costituzionalizzazione’ del diritto privato. Ne derivano rilevanti implicazioni – a volte sicuramente positive, altre volte però preoccupanti – sia sul piano della giurisprudenza sia su quello dottrinario.

description: Deep learning-based melanoma classification with dermoscopic images has recently shown great potential in automatic early-stage melanoma diagnosis. However, limited by the significant data imbalance and obvious extraneous artifacts, i.e., the hair and ruler markings, discriminative feature extraction from dermoscopic images is very challenging. In this study, we seek to resolve these problems respectively towards better representation learning for lesion features. Specifically, a GAN-based data augmentation (GDA) strategy is adapted to generate synthetic melanoma-positive images, in conjunction with the proposed implicit hair denoising (IHD) strategy. Wherein the hair-related representations are implicitly disentangled via an auxiliary classifier network and reversely sent to the melanoma-feature extraction backbone for better melanoma-specific representation learning. Furthermore, to train the IHD module, the hair noises are additionally labeled on the ISIC2020 dataset, making it the first large-scale dermoscopic dataset with annotation of hair-like artifacts. Extensive experiments demonstrate the superiority of the proposed framework as well as the effectiveness of each component. The improved dataset publicly avaliable at https://github.com/kirtsy/DermoscopicDataset.

description: External galaxies often intervene in front of background radio sources such as quasars and radio galaxies. Linear polarization of the background emission is depolarized by Faraday rotation of inhomogeneous magnetized plasma of the intervening galaxies. Exploring the depolarizing intervening galaxies (DINGs) can be a powerful tool to investigate the cosmological evolution of the galactic magnetic field. In this paper, we investigate the effects of DINGs on background radio emission using theoretical DING models. We find that complex structures of galaxy result in complicated depolarization features and the Faraday dispersion functions (FDFs), but, for the features of depolarizations and FDFs, the global component of magnetic fields is important. We show the simplest results with ring magnetic field in the galactic disk. We find that the degree of depolarization significantly depends on the inclination angle and the impact parameter of the DING. We found that the larger the standard deviation, the more likely it is that depolarization will occur. The FDF represents the RM structure within the beam. The FDF exhibits multi-components due mainly to the RM structure within the beam and the fraction of the DING that covers the background emission (the filling factor). The peak Faraday depth of the FDF is different from the beam-averaged RM of the DING. The Monte-Carlo simulations indicate that DING's contribution to the standard deviation of observed RMs follows $σ_{\rm RM} \propto 1/{(1+z)^k}$ with $k \sim 2.7$ and exhibits a steeper redshift dependence than the wavelength squared. DINGs will have a significant impact on RM catalogs created by future survey projects such as the SKA and SKA Precursor/Pathfinder.

description: As a designer, I am influenced by the appearance and tactility of the materials that surround me. I notice their color, shape, texture, type and decoration. My subconscious records these details and replays them as I design. I have a particular affinity for things with history. For this reason I am drawn to the collection of materials that once belonged to ancestors and family members residing in my grandmother's attic. These items range from fine china and linens to boxes of letters, photographs, toys, and other ephemeral materials. I initially justified my interest in documenting this collection as a way to use my graphic design skills in service to my grandmother, who feels compelled to plan a way to distribute her things to her descendants before her death. However, I am also compelled to record the collection as bones in the skeleton of my own identity. "In the West, the fact of collecting is linked to the construction of identity. Baudrillard points out that it is "a dimension of our lives that is both essential and imaginary, as essential as dreams themselves."1 By handling the material things that surrounded my ancestors when they lived, I hope to divine something of who they were and how much of them is in me. All of the choices they made, minor or major,led to my existence, and perhaps my disposition. In some way these objects retain a memory of all the things that involved them, much like German psychologist Ewald Hering "concluded that every living cell contains the memory of the experience of the entire series of its parent cells and even those of former generations... every moment leaves traces that continue to affect all subsequent physical or mental processes. The past collects in the fibers of the body as it does in the mind and determines the way we walk and dance as well as the way we think."

description: In recent years, two competitive time series classification models, namely, ROCKET and MINIROCKET, have garnered considerable attention due to their low training cost and high accuracy. However, they rely on a large number of random 1-D convolutional kernels to comprehensively capture features, which is incompatible with resource-constrained devices. Despite the development of heuristic algorithms designed to recognize and prune redundant kernels, the inherent time-consuming nature of evolutionary algorithms hinders efficient evaluation. To efficiently prune models, this paper eliminates feature groups contributing minimally to the classifier, thereby discarding the associated random kernels without direct evaluation. To this end, we incorporate both group-level ($l_{2,1}$-norm) and element-level ($l_2$-norm) regularizations to the classifier, formulating the pruning challenge as a group elastic net classification problem. An ADMM-based algorithm is initially introduced to solve the problem, but it is computationally intensive. Building on the ADMM-based algorithm, we then propose our core algorithm, POCKET, which significantly speeds up the process by dividing the task into two sequential stages. In Stage 1, POCKET utilizes dynamically varying penalties to efficiently achieve group sparsity within the classifier, removing features associated with zero weights and their corresponding kernels. In Stage 2, the remaining kernels and features are used to refit a $l_2$-regularized classifier for enhanced performance. Experimental results on diverse time series datasets show that POCKET prunes up to 60% of kernels without a significant reduction in accuracy and performs 11$\times$ faster than its counterparts.
