description: Functional and structural studies on glycoproteins are hampered by lack of homogeneous structures due to the inherent structural heterogeneity in the pendant glycans which makes separation by routine chromatographic techniques extremely difficult. To address this problem, we used a chemoenzymatic method to make homogeneous glycopeptides and glycoproteins, which relies on the glycosynthase-based transglycosylation of a GlcNAc-peptide/protein using synthetic glycan oxazoline as the enzyme substrate. The thesis research presented here consists of three projects.   First, we synthesized selectively fluorinated homogeneous Man3GlcNAc2-RNase glycoproteins for binding studies to the concanavalin A (con A) lectin. From SPR analysis, we observed that fluorine substitution at the C6-hydroxyl of the α-1,6-branched mannose residue of the   Man3GlcNAc2 negated lectin binding suggesting the importance of that hydroxyl group in binding interactions. We found that the fluorinated glycan oxazoline corresponding to the Man3GlcNAc core could serve as an excellent substrate for the Endo-A enzyme during transglycosylation and a structural modeling analysis of the Endo-A enzyme binding pocket suggested favorable hydrophobic interactions between a suitably located tyrosine and the fluorine. This suggest that the selectively fluorinated glycoproteins can be used to probe specific protein-carbohydrate interactions. Secondly, we synthesized homogeneous HIV-1 V3 glycopeptides for characterizing the epitope of a recently discovered, potent anti-HIV-1 broadly neutralizing antibody (bnAb) PGT121 and related antibody 1074. SPR binding analysis indicated that antibody PGT121 recognizes complex type N-glycan while the PGT121-like antibody 10-1074 binds to high-mannose type N-glycan (Man9GlcNAc2) in the context of the V3 domain. Interestingly, these antibodies did not bind to free N-glycans or non-glycosylated V3 polypeptides under the same conditions. This study has facilitated the characterization of the glycan specificity of the two anti-HIV antibodies.  Finally, we designed and synthesized a novel multifunctional BALT tag for separation of N-glycans for functional glycomics applications. It consists of an N-methylhydroxylamine group for attachment to reducing ends of glycans with preservation of ring structure, free primary amine for immobilization to microarrays, tyrosine group providing a chromophore and hydrophobicity during chromatographic separation and biotin for binding to streptavidin. The tag was successfully used for separation and recovery of individual N-glycans from a mixture of four N-glycans released from the glycoprotein bovine fetuin.

description: We present constraints on the presence of isocurvature modes from the temperature and polarization CMB spectrum data from the WMAP satellite alone, and in combination with other datasets including SDSS galaxy survey and SNLS supernovae. We find that the inclusion of polarization data allows the WMAP data alone, as well as in combination with complementary observations, to place improved limits on the contribution of CDM and neutrino density isocurvature components individually. With general correlations, the upper limits on these sub-dominant isocurvature components are reduced to ~60% of the first year WMAP results, with specific limits depending on the type of fluctuations. If multiple isocurvature components are allowed, however, we find that the data still allow a majority of the initial power to come from isocurvature modes. As well as providing general constraints we also consider their interpretation in light of specific theoretical models like the curvaton and double inflation.

description: Despite a lack of empirical evidence of an academic advantage from delayed kindergarten entry, some parents choose to delay their child. School readiness training programs could impact parent inclination to delay kindergarten entry. Therefore, the purpose of the present study was to examine how a school readiness plus behavior parent training program, compared to behavior training alone, affected parent perceptions about their child's school readiness, their personal ability to help their child succeed in school, and parent's likelihood to delay their child's entry into kindergarten. Sixty parents from an upper-middle class suburban area, with preschool-aged children, were randomly assigned to the school readiness plus behavior training group or the behavior training only comparison group. Both groups received behavior training, but only the school readiness group received training based on The Incredible Years Parenting Program.  Parents were assessed before and after 4 weeks of training. Assessments included the Parent Efficacy to Help My Child Succeed in School Scale and a Parent Questionnaire designed specifically to measure the school readiness and behavior skills taught to the training groups, the Eyberg Child Behavior Inventory and the Parenting Stress Index.  Analysis of variance revealed that the School Readiness group improved on skills taught specifically to their group, whereas the behavior only group did not, validating the differences in training content.  Both training programs were effective in significantly reducing parent stress, raising parental efficacy, and improving parent perceptions of their child's behaviors. The participants in the school readiness group who were initially inclined to delay their child's school entry significantly decreased their likelihood to delay post training. Further exploration revealed that these findings were not related to demographics, such as gender, age, or parent education. These findings suggest that parent training programs can significantly improve both parent efficacy and parent stress as well as parent perceptions about their child's school readiness.

description: We study edges states of graphene ribbons in the quantized Hall regime, and show that they can be described within a continuum model (the Dirac equation) when appropriate boundary conditions are adopted. The two simplest terminations, zigzag and armchair edges, are studied in detail. For zigzag edges, we find that the lowest Landau level states terminate in two types of edge states, dispersionless and current-carrying surface states. The latter involve components on different sublattices that may be separated by distances far greater than the magnetic length. For armchair edges, the boundary conditions are met by admixing states from different valleys, and we show that this leads to a single set of edges states for the lowest Landau level and two sets for all higher Landau levels. In both cases, the resulting Hall conductance step for the lowest Landau level is half that between higher Landau levels, as observed in experiment.

description: Falls are a major cause of injuries in adults above the age of sixty-ve. The economic aftermath of falls and their consequent hospitalization can be extensive. A plausible way of mitigating this problem is accurate prediction of future falls and taking proactive remedial action. Problems in gait is a reliable indicator of a future fall, however, existing systems focus on gait analysis in clinical settings and are not tuned towards continuous gait analysis. This research presents the design of a novel textile capacitive sensor array-based system built into clothing that can reliably capture advanced pedometric parameters that can be used to determine gait attributes. The nal design utilizes hierarchical signal processing architecture that breaks down the signal processing algorithm into a hierarchy of processing elements. The system is prototyped using textile capacitive plates built into an elastic-bandage and a custom FPGA-based system and show that our system can accurately detect gait attributes that have high correlation with falls, while consuming minimal energy.
Emergence of multistability and strongly asymmetric collective modes in two quorum sensing coupled identical ring oscillators

description: The simplest ring oscillator is made from three strongly nonlinear elements repressing each other unidirectionally resulting in the emergence of a limit cycle. A popular implementation of this scheme uses repressive genes in bacteria creating the synthetic genetic oscillator known as the Repressilator. Here, we consider the main collective modes produced when two identical Repressilators are mean-field coupled via the quorum sensing (QS) mechanism which is realized via production of diffusive signal molecules. Using the rate of the repressor's production and the value of coupling strength as the bifurcation parameters, we performed analysis of dynamical regimes starting from the two Andronov-Hopf bifurcations of unstable homogeneous steady state, which generate in-phase and anti-phase limit cycles. Pitchfork bifurcation of the unstable in-phase cycle leads to creation of inhomogeneous limit cycles with very different amplitudes in contrast to well-known asymmetrical limit cycles arising from oscillation death. Neimark-Sacker bifurcation of the anti-phase cycle determines the border of an island in two-parameter space containing almost all the interesting regimes including the set of resonant limit cycles, the area with stable inhomogenous cycle, and very large areas with chaotic regimes resulting from torus destruction, period doubling of resonant cycles and inhomogenous cycles. We discuss the structure of chaos skeleton to show the role of inhomogeneous cycles in its formation. Many regions of multistability and transitions between regimes are presented. These results provide new insights into the coupling-dependent mechanisms of multistability and collective regime symmetry breaking in populations of identical multidimensional oscillators.

The 3-state model has a phase transition to the high-temperature disordered phase at v = e^J - 1 = -0.860599 +- 0.000004 that appears to be in the universality class of the 3-state Potts ferromagnet. The 4-state model is disordered throughout the physical region, including at zero temperature.

description: Dust properties within a galaxy are known to change from the diffuse medium to dense clouds due to increased local gas density. However, the question of whether dust properties change with redshift remains elusive. In this paper, using the fact that the mean radiation intensity of the interstellar medium (ISM) of star-forming galaxies increases with redshift, we show that dust properties should change due to increasing efficiency of rotational disruption by radiative torques, an effect named RAdiative Torque Disruption (RATD). We first show that, due to RATD, the size distribution of interstellar dust varies with redshift, such as dust grains become smaller at higher $z$. We model the extinction curves and find that the curve becomes steeper with increasing redshift. The ratio of total-to-selective extinction, $R_{V}$, decreases with redshift and achieves low values of $R_{V}\sim 1.5-2.5$ for grains having a composite structure. We also find that dust properties change with the local gas density due to RATD, but the change is dominated by the radiation field for the diffuse ISM. The low values of $R_{V}$ implied by RATD of interstellar dust could reproduce anomalous dust extinction observed toward type Ia supernovae (SNe Ia) and Small Magellanic Cloud (SMC)-like extinction curves with a steep far-UV rise toward high-z galaxies. Fluctuations in $R_{V}$ due to interstellar turbulence and varying radiation intensity may resolve the tension in measurements of the Hubble constant using SNe Ia. We finally discuss the implications of evolving dust properties for high-z astrophysics.

Subjects: Psychology, Clinical (0622)

description: This study sought to extend the current body of knowledge related to exercise-induced analgesia through examination of the central modulation of pain (DNIC) and the psychological constructs of perceived physical fitness and in vivo pain catastrophizing. Participants completed questionnaires assessing their involvement in strenuous and non-strenuous exercise, perceptions of physical fitness, and catastrophic thoughts related to painful stimulation. Participants then underwent standardized experimental pain testing. Results showed that strenuous exercise involvement was significantly and inversely related to in vivo pain catastrophizing for males, B = -0.35, p = 0.03 but not females,    B = -0.16, p = 0.31.  Further, less in vivo catastrophizing was significantly related to greater baseline pressure pain thresholds, B = -0.25, p = 0.03 and cold pressor tolerance, B = -0.26, p = 0.02. Despite these relationships, strenuous exercise involvement was not directly related to DNIC or other pain outcomes (e.g., baseline PPT, CPT tolerance). Additionally, in vivo catastrophizing was not shown to be a significant mediator for any of the proposed relationships among strenuous exercise involvement, perceived physical fitness, and pain outcomes. None of the proposed mediated relationships were found to be moderated by participants' sex. Pain catastrophizing has consistently been shown to be predictive of pain outcomes. This study's findings suggest that, at least in males, strenuous exercise involvement may be a potentially efficacious intervention for positively affecting pain outcomes given the inverse relationship between greater strenuous exercise involvement and less pain catastrophizing. Limitations and implications for future research are discussed in greater detail.

description: We study the branching fractions and the lepton polarization asymmetries of rare $B \to X_s τ^+ τ^-$ and $B \to K^{(*)} τ^+ τ^-$ modes within the Standard Model and in the Appelquist-Cheng-Dobrescu model, which is a New Physics scenario with a single universal extra dimension. In particular, we investigate the sensitivity of the observables to the radius $R$ of the compactified extra-dimension, which is the only new parameter in this New Physics model. For the exclusive transitions we study the uncertainties due to the hadronic matrix elements using two set of form factors, finding that in many cases such uncertainties are small. In particular, we show that the $τ^-$ polarization asymmetries become free of hadronic uncertainties if Large Energy relations for the form factors, valid for low momentum transfer to the lepton pair, are used. We also consider $K^*$ helicity fractions and their sensitivity to the compactification parameter.

description: Previous research has shown that amendment of activated carbon and other sorbents can be a viable option for the remediation of sites contaminated with organic or inorganic contaminants. These options could serve as alternative or additional solutions to current remediation strategies. The research documented in this thesis, illustrates the potential for application of these treatment materials to contaminated sites.  Dissolved metals in sediment pore water constitute an important route of exposure to benthic organisms. Therefore, aqueous phase metal sorptivity of various sorbents was evaluated to select suitable amendments that could be used to reduce sediment pore water metal concentrations. Based on pH- edge sorption tests, natural sorbents were eliminated due to inferior performance. Selected amendments were tested in fresh and salt- water matrices and were shown to reduce bioavailability of metal contaminants by reducing the bioavailable fraction of metals in sediment and sediment pore water.  A low- impact delivery system for treatment materials was developed and tested in laboratory mesocosms and shown to successfully deliver treatment materials through a water column to the sediment surface. Mixing of the treatment amendments in the surficial sediment layer was achieved through natural bioturbation of the benthic organisms. Delivered sorbent materials were shown to effectively reduce the bioaccumulation of organic contaminants by 40 % in a 10- day exposure period, and by 55% in a 28- day exposure period. This delivery system can be tailored to deliver various amendments to contaminated sediments.

description: We develop integration-by-parts rules for Feynman diagrams involving massive scalar propagators in a constant background electromagnetic field, and use these to show that there is a simple diagrammatic interpretation of mass renormalization in the two-loop scalar QED Heisenberg-Euler effective action for a general constant background field. This explains why the square of a one-loop term appears in the renormalized two-loop Heisenberg-Euler effective action. No integrals need be evaluated, and the explicit form of the background field propagators is not needed. This dramatically simplifies the computation of the renormalized two-loop effective action for scalar QED, and generalizes a previous result obtained for self-dual background fields.

description: The Zwicky Transient Facility (ZTF) has discovered five new events belonging to an emerging class of AGN undergoing smooth flares with large amplitudes and rapid rise times. This sample consists of several transients that were initially classified as supernovae with narrow spectral lines. However, upon closer inspection, all of the host galaxies display resolved Balmer lines characteristic of a narrow-line Seyfert 1 (NLSy1) galaxy. The transient events are long-lived, over 400 days on average. We report UV and X-ray follow-up of the flares and observe persistent UV-bright emission, with two of the five transients detected with luminous X-ray emission, ruling out a supernova interpretation. We compare the properties of this sample to previously reported flaring NLSy1 galaxies, and find that they fall into three spectroscopic categories: Transients with 1) Balmer line profiles and Fe II complexes typical of NLSy1s, 2) strong He II profiles, and 3) He II profiles including Bowen fluorescence features. The latter are members of the growing class of AGN flares attributed to enhanced accretion reported by Trakhtenbrot et al. (2019). We consider physical interpretations in the context of related transients from the literature. For example, two of the sources show high amplitude rebrightening in the optical, ruling out a simple tidal disruption event scenario for those transients. We conclude that three of the sample belong to the Trakhtenbrot et al. (2019) class, and two are TDEs in NLSy1s. We also aim to understand why NLSy1s are preferentially the sites of such rapid enhanced flaring activity.

Psychology, Physiological (0989)

description: African Americans have disproportionately high rates of cardiovascular disease (CVD) that remain poorly understood.  Biopsychosocial research on depression could prove informative regarding such disparities in CVD.  Both major depression and less severe subclinical levels of depressive symptoms have been linked to increased risk for CVD in prospective studies.  Given the evidence that subclinical depression is more prevalent in African Americans than Caucasians, it could contribute to population differences in CVD.  Among the potential mechanisms underlying depression-CVD relations are hemodynamic, metabolic, and anthropometric risk factors for CVD that might be potentiated by depressive symptoms.  Reports suggest that depression differentially influences CVD risk factors according to gender, but scant information is available about these variations among African Americans.  This information gap was addressed by the examination of gender for interactive effects with depressive symptoms, as measured with the Center for Epidemiologic Studies-Depression (CES-D), on a spectrum of cardiovascular risk factors. Participants were 734 African Americans (320 men, 414 women; ages 30 to 64) from the Healthy Aging in Neighborhoods of Diversity Across the Lifespan (HANDLS) Study in Baltimore, MD.  Separate multiple regressions examined CES-D x Gender as a predictor of nine anthropometric, hemodynamic, and metabolic risk factors for CVD.  These included body mass index (BMI), waist circumference (WC), resting measures of systolic and diastolic blood pressure (SBP, DBP), as well as fasting measures of total serum cholesterol (TSC), low- and high-density lipoprotein cholesterol (LDL-C, HDL-C), triglycerides (TG), and glucose (GLU).  Regressions were adjusted for age, BMI (except in analyses of BMI as a risk factor), poverty status, smoking, alcohol, and medical comorbidities. The CES-D x Gender interaction predicted WC, SBP, DBP, LDL-C, HDL-C, and TG, along with a main effect of increasing CES-D scores on decreasing TSC.  Subsequent gender-stratified regressions showed that increases in depressive symptoms among African American women were related to clinically relevant decreases in HDL-C and increases in WC, SBP, and DBP.  Among African American men, increasing depressive symptoms were associated with increasing HDL-C and decreasing LDL-C and TG. Subclinical depression may operate differently across gender to confer greater cardiovascular risk among African American women than African American men.

description: In biomedical wearable devices, patient's convenience and accuracy are the main priorities. To fulfill the patient's convenience requirement, the power consumption, which directly translates to the battery lifetime and size, must be kept as low as possible. Meanwhile, adopted improvements should not impact the accuracy. Therefore, focus on reducing the energy consumption within these devices has already been the subject of a significant amount of research in the past few years. In most wearable devices, all raw data is transmitted to a computer to carry out the required processing. This vast amount of communication leads to a considerable amount of power consumption and the need for a bulky battery, which hinders the device's practicality and patient's convenience. Tongue Drive System (TDS) is a new unobtrusive, wireless, and wearable assistive device that allows for real time tracking of the voluntary tongue motion in the oral space for communication, control, and navigation applications. The intraoral TDS clasps to the upper teeth and resists sensor misplacement. However, the iTDS has more restrictions on its dimensions, limiting the battery size and consequently requiring a considerable reduction in its power consumption to operate over an extended period of two days on a single charge. In this thesis, we propose an ultra low power local processor for the TDS that performs all signals processing on the transmitter side, following the sensors. Implementing the computational engine reduces the data volume that needs to be wirelessly transmitted to a PC or smartphone by a factor of 30x, from 12 kbps to ~400 bps. The proposed design is implemented on an ultra low power IGLOO nano FPGA and is tested on AGLN250 prototype board. According to our post place and route results, implementing the engine on the FPGA significantly drops the required data transmission, while an ASIC implementation in 65 nm CMOS results in 0.128 mW power consumption and occupies a 0.02 〖mm〗^2 footprint. To explore a different architecture, we mapped our proposed TDS processor on the EEHPC many-core. The many-core has a flexible and time saving design procedure. As a result of having a local processor, the power consumption and size of the iTDS will be significantly reduced through the use of a much smaller rechargeable battery. Moreover, the system can operate longer following every recharge, improving the iTDS usability.

description: Possible detection of signatures of structure formation at the end of the 'dark age' epoch (z~40-20) is examined. We discuss the spectral-spatial fluctuations in the CMBR temperature produced by elastic resonant scattering of CMBR photons on HD molecules located in protostructures moving with peculiar velocity. Detailed chemical kinematic evolution of HD molecules in the expanding homogeneous medium is calculated. Then, the HD abundances are linked to protostructures at their maximum expansion, whose properties are estimated by using the top-hat spherical approach and the LambdaCDM cosmology. We find that the optical depths in the HD three lowest pure rotational lines for high-peak protohaloes at their maximum expansion are much higher than those in LiH molecule. The corresponding spectral-spatial fluctuation amplitudes however are probably too weak as to be detected by current and forthcoming millimeter-telescope facilities. We extend our estimates of spectral-spatial fluctuations to gas clouds inside collapsed CDM haloes by using results from a crude model of HD production in these clouds. The fluctuations for the highest-peak CDM haloes at redshifts ~20-30 could be detected in the future. Observations will be important to test model predictions of early structure formation in the universe.

description: The influence of functionalised graphene nanoplatelets with melamine on the thermal and mechanical properties of a 3D-printed photopolymerisable resin is investigated. In this work, a liquid-based 3D printer and stereolithography were employed to fabricate the 3D-printed parts, and a commercial dimethacrylate-based resin was used. The 3D-printed parts were subjected to ultraviolet and thermal post-curing stages to improve thermal and mechanical behaviour. The quality of the graphene nanoplatelets’ functionalisation was characterised by Fourier transform infrared spectroscopy and thermogravimetric analysis. Thermal and mechanical characterisations were performed via thermogravimetric, tensile, and Izod impact tests. The fractured surfaces were observed via scanning electron microscopy. The degree of graphene nanoplatelet dispersion in the polymer matrix is enhanced by bonding with melamine via π–π interactions and inhibited surface defect formation. Results show property enhancements of up to 35% in tensile strength, 78% in impact strength, and 38% in residual weight at 400 ◦C.

description: Computing needs for high energy physics are already intensive and are expected to increase drastically in the coming years. In this context, heterogeneous computing, specifically as-a-service computing, has the potential for significant gains over traditional computing models. Although previous studies and packages in the field of heterogeneous computing have focused on GPUs as accelerators, FPGAs are an extremely promising option as well. A series of workflows are developed to establish the performance capabilities of FPGAs as a service. Multiple different devices and a range of algorithms for use in high energy physics are studied. For a small, dense network, the throughput can be improved by an order of magnitude with respect to GPUs as a service. For large convolutional networks, the throughput is found to be comparable to GPUs as a service. This work represents the first open-source FPGAs-as-a-service toolkit.

Relations among pain appraisal, pain catastrophizing, and cardiovascular reactivity

description: Both the meaning that is ascribed to pain (e.g., cognitive appraisal) and the way in which individuals cope with pain are important predictors of clinical outcomes among patients with chronic pain.  Few experimental studies of appraisal and pain-coping styles, however, have investigated physiological outcomes, although these appear to be as important measures to examine in chronic pain sufferers.  Physiological measures (e.g., cardiovascular, immunologic, genetic) warrant inclusion and rigorous exploration in studies, as they may shed light on the processes that underlie cardiovascular disease morbidity and mortality observed among individuals with chronic pain.  In this study, the relations of cognitive pain appraisals and styles of pain coping to cardiovascular reactivity (e.g., excessive cardiovascular response to stress) and affect were examined in seventy-eight healthy female participants.  Measures of systolic blood pressure, diastolic blood pressure, heart rate, cardiac index, and total peripheral resistance were assessed at rest and during the forehead cold pressor test.  Participants also completed measures of pain appraisal, pain coping, and positive and negative affect prior to and following the cold pressor test.  Results indicated that higher self-reported threat appraisal independently predicted greater systolic (t(69) = 5.02, p < .05) and diastolic (t(69) = 5.59, p < .05) blood pressure reactivity.  Cardiovascular responses were not predicted by the challenge appraisal measure.  Threat appraisals predicted greater negative affect (R2 = .29), whereas challenge appraisals were related to greater positive affect (R2 = .34).  Styles of pain coping, including pain catastrophizing (e.g., a negative cognitive-affective response), were unrelated to task-related changes in cardiovascular functioning.  Thus, our results do not support pain catastrophizing as a mediator of the effect of threat appraisal on total peripheral resistance.  A second model examining active coping strategies (i.e., effective strategies used to control or to function despite pain) as mediators between challenge appraisal and increased cardiac output was similarly unsupported.  Our findings do, however, highlight the importance of appraisals and their impact on affect and physiological responses to pain.  Future interventions that target reductions in the threat value of pain may help to reduce the negative impact of pain on the cardiovascular system.
