description: We show that metal-insulator transition in Pr0.5Ca0.5Mn1-xCrxO3 (x = 0.015-0.025) is unstable against thermal cycling. Insulator-metal transition shifts down and low temperature resistivity increases each time when the sample is cycled between a starting temperature TS and a final temperature TF. The effect is dramatic lower is x. Insulator-metal transition in x = 0.015 can be completely destroyed by thermal cycling in absence of magnetic field as well as under H = 2 T. Magnetic measurements suggest that ferromagnetic phase fraction decreases with thermal cycling. We suggest that increase in strains in ferromagnetic- charge ordered interface could be a possible origin of the observed effect.

description: Collisions of galaxy clusters generate shocks and turbulence in the intra-cluster medium (ICM). The presence of relativistic particles and magnetic fields is inferred through the detection of extended synchrotron radio sources such as haloes and relics and implies that merger shocks and turbulence are capable of (re-)accelerating particles to relativistic energies. However, the precise relationship between merger shocks, turbulence, and extended radio emission is still unclear. Studies of the most simple binary cluster mergers are important to help understand the particle acceleration in the ICM. Our main aim is to study the properties of the extended radio emission and particle acceleration mechanism(s) associated with the generation of relativistic particles in the ICM. We measure the low-frequency radio emission from the merging galaxy cluster Abell 2146 with LOFAR at 144 MHz. We characterize the spectral properties of the radio emission by combining these data with data from archival GMRT at 238 MHz and 612 MHz and VLA at 1.5 GHz. We observe extended radio emission at 144 MHz behind the NW and SE shocks. Across the NW extended source, the spectral index steepens from $-1.06\pm0.06$ to $-1.29\pm0.09$ in the direction of the cluster centre. This spectral behaviour suggests that a relic is associated with the NW upstream shock. The precise nature of the SE extended emission is unclear. It may be a radio halo bounded by a shock or a superposition of a relic and halo. At 144 MHz, we detect a faint emission that was not seen with high-frequency observations, implying a steep ($α

description: A way to considerably enhance terahertz radiation, emitted in the interaction of intense mid-infrared laser pulses with atomic gases, in both the total energy and the electric-field amplitude is suggested. The scheme is based on the application of a two-color field consisting of a strong circularly polarized mid-infrared pulse with wavelengths of $1.6÷4\,μ{\rm m}$ and its linearly or circularly polarized second harmonic of lower intensity. By combining the strong-field approximation for the ionization of a single atom with particle-in-cell simulations of the collective dynamics of the generated plasma it is shown that the application of such two-color circularly polarized laser pulses may lead to an order-of-magnitude increase in the energy emitted in the terahertz frequency domain as well as in a considerable enhancement in the maximal electric field of the terahertz pulse. Our results support recently reported experimental and numerical findings.

description: We have measured low-temperature specific heat C(T, H) of La1.9Sr0.1Cu1-xZnxO4 (x=0, 0.01, and 0.02) both in zero and applied magnetic fields. A pronounced dip of C/T below 2 K was first observed in Zn-doped samples, which is absent in the nominally clean one. If the origin of the dip in C/T is electronic, the quasiparticle density of states N(E) in Zn-doped samples may be depressed below a small energy scale E0. The present data can be well described by the model N(E)=N(0)+alphaE^1/2, with a non-zero N(0) and positive alpha. Magnetic fields depress N(0) and lead to an increase in E0, while leaving the energy dependence of N(E) unchanged. This novel depression of N(E) below E0 in impurity-doped cuprates can not be reconciled with the semi-classical self-consistent approximation model. Discussions in the framework based on the non-linear sigma model field theory and other possible explanations are presented in this Letter.

description: Recent experiments suggest that shear-enhanced growth of concentration fluctuations in polymer solutions is strongly influenced by solid boundaries. We analyze the dynamics of a model of a sheared polymer solution, accounting for the effect of stress variations on mass flux and for wall-slip. If (and only if) these effects are present, the flow exhibits a boundary-localized instability consistent with experimental observations. Even in the absence of flow instability, thermally-driven concentration fluctuations are significantly enhanced near the boundary.

description: We report on growth of InP-InAs core-shell nanowires and demonstration of the formation of single quantum structures, which show Coulomb blockade effect, over entire lengths of the nanowires. The core-shell nanowires are grown by a selective area growth technique via metal-organic vapor phase epitaxy. The as-grown core-shell nanowires are found to be of wurtzite crystals. The InP cores have a hexagonal cross section, while the InAs shell are grown preferentially on specific {1$\bar{1}$00} facets, leading to the formation of the core-shell nanowires with an overall triangular cross section. The grown core-shell nanowires are transferred on to a Si/SiO$_2$ substrate and then contacted with several narrow metal electrodes. Low-temperature transport measurements show the Coulomb-blockade effect. We analyze the measured gate capacitance and single electron charging energy of the devices and demonstrate that a quantum structure which shows the Coulomb blockade effect of a many-electron quantum dot is formed over the full length of a single core-shell nanowire and consists of the entire InAs shell in the nanowire.

Stochastic optimization

description: Stochastic Gradient Descent (SGD) has played a crucial role in the success of modern machine learning methods. The popularity of SGD arises due to its ease of implementation, low memory and computational requirements, and applicability to a wide variety of optimization problems. However, SGD suffers from numerous issues; chief amongst them are high variance, slow rate of convergence, poor generalization, non-robustness to outliers, and poor performance for imbalanced classification. In this thesis, we propose variants of stochastic gradient descent, to tackle one or more of these issues for different problem settings. In the first chapter, we analyze the trade-off between variance and complexity to improve the convergence rate of SGD. A common alternative in the literature to SGD is Stochastic Variance Reduced Gradient (SVRG), which achieves linear convergence. However, SVRG involves the computation of a full gradient every few epochs, which is often intractable. We propose the Cheap Stochastic Variance Reduced Gradient (CheapSVRG) algorithm that attains linear convergence up to a neighborhood around the optimum without requiring a full gradient computation step. In the second chapter, we aim to compare the generalization capabilities of adaptive and non-adaptive methods for over-parameterized linear regression. Of the many possible solutions, SGD tends to gravitate towards the solution with minimum l2-norm while adaptive methods do not. We provide specific conditions on the pre-conditioner matrices under which a subclass of adaptive methods has the same generalization guarantees as SGD for over-parameterized linear regression. With synthetic examples and real data, we show that minimum norm solutions are not an excellent certificate to guarantee better generalization. In the third chapter, we propose a simple variant of SGD that guarantees robustness. Instead of considering SGD with one sample, we take a mini-batch and choose the sample with the lowest loss. For the noiseless framework with and without outliers, we provide conditions for the convergence of MKL-SGD to a provably better solution than SGD in the worst case. We also perform the standard rate of convergence analysis for both noiseless and noisy settings. In the final chapter, we tackle the challenges introduced by imbalanced class distribution in SGD. In place of using all the samples to update the parameter, our proposed Balancing SGD (B-SGD) algorithm rejects samples with low loss as they are redundant and do not play a role in determining the separating hyperplane. Imposing this label-dependent loss-based thresholding scheme on incoming samples allows us to improve the rate of convergence and achieve better generalization.

description: Three different clusters, Si_9H_12, Si_15H_16, and Si_21H_20, are used in density-functional theory calculations in conjunction with ab initio pseudopotentials to study how the energetics of H_2 dissociativ e adsorption on and associative desorption from Si(001) depends on the cluster size. The results are compared to five-layer slab calculations using the same pseudopotentials and high qu ality plane-wave basis set. Several exchange-correlation functionals are employed. Our analysis suggests that the smaller clusters generally overestimate the activation barriers and reaction energy. The Si_21H_20 cluster, however, is found to predict reaction energetics, with E_{a}^{des}=56 +- 3 kcal/mol (2.4 +- 0.1 eV), reasonably close (though still different) to that obtained from the slab calculations. Differences in the calculated activation energies are discussed in relation to the efficiency of clusters to describe the properties of the clean Si(001)-2x1 surface.

The modern MPI3 feature of asynchronous communication is an essential ingredient of the computing model. Parallel numerical evaluation applies both to phase-space integration and to event generation, thus covering the most computing-intensive parts of physics simulation for a realistic collider environment.

description: Millimeter-wave (mmWave) communication and radar are key technologies for many demanding applications, such as autonomous driving and smart connected devices. The combination of these two technologies into a single joint communication-radar (JCR) enables hardware reuse and a common signaling waveform. This leads to significant benefits in power consumption, spectrum efficiency, and market penetrability. Prior work has proposed a mmWave wireless local area network-based JCR, which provides a good baseline for designing a future mmWave JCR standard. These JCR systems, however, incurred limited radar estimation performance. In this dissertation, we present advanced adaptive JCR waveform and beamforming designs to achieve superior radar performance, at the cost of a small reduction in the communication rate. These contributions are foundational for the development of futuristic standard-based mmWave JCR systems in automotive applications. The summary of our contributions is as follows. First, we propose a virtual waveform design for an adaptive mmWave JCR to enhance velocity estimation accuracy without reducing the communication data rate much. We formulate three different minimum mean square error-based optimization problems for the adaptive JCR waveform design. We solve the JCR optimization problems for a uniform waveform as well as for nested and Wichmann virtual waveforms. Numerical results demonstrate that optimal virtual waveforms achieve significant performance improvements over a uniform waveform, especially at low SNR and high target density. Second, this dissertation presents a low-complexity fully-digital multiple-input-multiple-output measurement platform, named JCR70, to evaluate and demonstrate the JCR performance in the 71-76 GHz band. Additionally, an experimental proof-of-concept is also performed for low-resolution analog-to-digital converters by emulating quantization effect on the collected data. The JCR70 platform demonstrated higher resolution capability than the Radarbook, which is a leading automotive radar evaluation platform at 77 GHz. Finally, this dissertation develops an adaptive combined waveform-beamforming design for automotive mmWave JCR that uses a phased-array architecture. To estimate the radar channel in the Doppler-angle domain with a wide field-of-view, all the transmit antennas are used to generate a narrow coherent beam for communication and distribute the remaining energy uniformly along other radar sensing directions. By applying partial Fourier compressed sensing technique, the framework is shown to estimate radar channels with high accuracy, at the cost of a small reduction in the communication rate.
Quiet Region Jet by Eruption of Minifilament and Associated Change in Magnetic Flux

description: We observe a coronal jet around 22:08 UT on 23 rd March of 2017, in a quiet region towards the north-east of the solar disk. A minifilament eruption leads to this jet. We analyze dynamics of the minifilament from its formation until its eruption. We observe that the minifilament starts forming around 15:50 UT. Then at a later time, it disappears but again appears and finally erupts as a blowout jet around 22:08 UT. We study the evolution of photospheric magnetic field beneath the minifilament. Initially, we observe subsequent increase and decrease of positive magnetic flux. Prior to the initiation of the eruption, positive magnetic flux shows a continuous decrease until the minifilament disappears. The positive magnetic flux increases and decreases due to new positive flux emergence and cancellation of positive magnetic flux with negative magnetic flux respectively.

description: Infrastructure and construction projects are large, complex, and arduous ventures involving various actors or stakeholders. However, taking decisions based on the individual attributes of stakeholders is insufficient. The emergence of the private sector in Public-Private Partnership (PPP) projects reveal the need to consider how multiple stakeholders in an inter-reliant network can impact the project’s performance. This research uses stakeholder and social network theories, and analyzes the centrality measures – total-degree, betweenness, closeness – of the key public and private entities against two project performance criteria: cost and schedule. Findings reveal that private sector becomes significantly more central in PPP projects, and there is a statistically significant correlation between private sector centrality measures and project schedule performance. In addition, the research reveals that the number of public agencies or sponsors involved in the project also plays a significant role in determining project performance

description: We examine the possible acceleration mechanisms of the relativistic particles responsible for the extended radio emission in Abell 520. We used new LOFAR 145 MHz, archival GMRT 323 MHz and VLA 1.5 GHz data to study the morphological and spectral properties of extended cluster emission. The observational properties are discussed in the framework of particle acceleration models associated with cluster merger turbulence and shocks. In Abell 520, we confirm the presence of extended synchrotron radio emission that has been classified as a radio halo. The comparison between the radio and X-ray brightness suggests that the halo might originate in a cocoon rather than from the central X-ray bright regions of the cluster. The halo spectrum is roughly uniform on the scale of 66 kpc. There is a hint of spectral steepening from the SW edge towards the cluster centre. Assuming DSA, the radio data are suggestive of a shock of $\mathcal{M}_{SW}=2.6_{-0.2}^{+0.3}$ that is consistent with the X-ray derived estimates. This is in line with the scenario in which relativistic electrons in the SW radio edge gain their energies at the shock front via acceleration of either thermal or fossil electrons. We do not detect extended radio emission ahead of the SW shock that is predicted if the emission is the result of adiabatic compression. An X-ray surface brightness discontinuity is detected towards the NE region that may be a counter shock of $\mathcal{M}_{NE}^{X}=1.52\pm0.05$. This is lower than the value predicted from the radio emission ($\mathcal{M}_{NE}=2.1\pm0.2$). Our observations indicate that the SW radio emission in Abell 520 is likely effected by the prominent X-ray detected shock in which radio emitting particles are (re-)accelerated through the Fermi-I mechanism. The NE X-ray discontinuity that is approximately collocated with an edge in the radio emission hints at the presence of a counter shock.

Competition between a rotating field and a shear flow originates a multiplicity of anomalous stress behaviors in suspensions of bounded dimers constituted by induced dipoles. The great variety of stress regimes includes non-monotonous behaviors, multi-resonances, negative viscosity effect and blockades. The reversibility of the transitions between the different regimes and the self-similarity of the stresses make this phenomenon controllable and therefore applicable to modify macroscopic properties of soft condensed matter phases

description: Millimeter wave (mmWave) bands offer several gigahertz of bandwidth that can support high data rate applications. To efficiently use the spectrum at mmWave frequencies, the wireless link between the transmitting and receiving radios must be configured properly. The link configuration problem at mmWave, however, is challenging due to the use of large antenna arrays and radio frequency (RF) impairments that are less severe in common lower frequency systems. Some of these impairments include the low resolution of RF phase shifters, carrier frequency offset, and the misfocus effect in near field systems with large arrays. An important characteristic of mmWave multiple-input multiple-output (MIMO) channels is sparsity. The sparse nature of such channels has allowed the use of compressed sensing (CS) for fast link configuration through channel estimation or beam alignment. CS techniques usually involve random sensing matrices to acquire a compressed channel representation and an optimization algorithm to estimate the sparse channel. Unfortunately, common random CS matrices result in poor link configuration under RF impairments. In the first part of this dissertation, we construct a new class of CS matrices that achieve robustness to the low resolution of RF phase shifters and the carrier frequency offset. To aid our construction, we propose a framework called FALP and develop an algorithm called Swift-Link within this framework. Swift-Link achieves better beam alignment than standard CS-based solutions at a reduced computational complexity. In the second part of this dissertation, we investigate the misfocus effect in near field beamforming. The beams in a near field communication scenario can focus RF signals in a spatial region called the focal point. The focal point, however, changes with the frequency of operation in a wideband phased array that uses a center frequency-based beamformer. This effect called misfocus, reduces the effective operating bandwidth of the near field system. To mitigate the misfocus effect, we propose a technique called InFocus that constructs beams which are well suited for massive wideband phased arrays. InFocus enables massive wideband phased array-based radios to achieve a higher data rate than comparable beamforming solutions.

description: Dolphins are marine mammals with unique anatomical structures in their airways. These particular respiratory structures make dolphins very sensitive to microorganisms in the air, and the habitats of dolphins in captivity and in the wild are quite different. This causes captive dolphins to suffer from illnesses, especially respiratory diseases. Previous studies have shown that the respiratory flora plays an essential role in the health of humans and animals. Therefore, by comparative analysis of the respiratory flora of wild dolphins and dolphins in captivity, we want to find the flora related to dolphins’ respiratory diseases, and try to improve dolphin health through flora homeostasis. For this purpose, we performed 16S rRNA gene sequencing and analyses. We found that Proteobacteria, Firmicutes, Actinobacteria, Campilobacterota, Paracoccus, and other flora differed between wild and healthy and sub-healthy captive dolphins. Some of them are the dominant flora for promoting health, and the others may be essential pathogenic bacteria in the sub-healthy state of dolphins in captivity.

description: Indiana University-Purdue University Indianapolis (IUPUI)
description: Introduction: A novel device developed by J. Morita can generate electromagnetic stimulation (EMS) into the root canal. Objectives: The purpose of this study was to determine the anti-biofilm effect of EMS combined with low concentrations of NaOCl against an established biofilm of Enterococcus faecalis in an in vitro human tooth model. Materials and Methods: Single rooted human teeth were standardized and an E. faecalis biofilm was established in the canal. The specimens were subject to six treatment groups: 1) 1.5% NaOCl; 2) 1.5% NaOCl and EMS; 3) 0.25% NaOCl; 4) 0.25% NaOCl and EMS; 5) saline and 6) saline and EMS. Biofilm was collected, plated, and the number of colony forming units (CFU)/mL was used to determine antibacterial activity. Results: The effect of treatment group on bacterial counts were made using one-way ANOVA followed by pair-wise comparisons. Although there was no significant difference between individual groups tested, there was statistically significant difference between the average difference between ‘treatments with EMS’ and ‘treatments without EMS.’ Conclusion: EMS can improve the antibacterial efficacy of NaOCl against an established biofilm of E. faecalis in an in vitro human tooth model
Jamming creep of a frictional interface

description: We measure the displacement response of a frictional multicontact interface between identical polymer glasses to a biased shear force oscillation. We evidence the existence, for maximum forces close below the nominal static threshold, of a jamming creep regime governed by an ageing-rejuvenation competition acting within the micrometer-sized contacting asperities. Quantitative analysis of the creep curves suggests that another such mechanism might be at work within the nanometer-thick adhesive junctions.

Polymers and manifolds in static random flows: a renormalization group study

description: We study the dynamics of a polymer or a D-dimensional elastic manifold diffusing and convected in a non-potential static random flow (the ``randomly driven polymer model''). We find that short-range (SR) disorder is relevant for d < 4 for directed polymers (each monomer sees a different flow) and for d < 6 for isotropic polymers (each monomer sees the same flow) and more generally for d2 and the velocity versus applied force characteristics is sublinear, i.e. at small forces v(f) f^phi with phi > 1. It indicates that this new state is glassy, with dynamically generated barriers leading to trapping, even by a divergenceless (transversal) flow. For random flows with long-range (LR) correlations, we find continuously varying exponents with the ratio gL/gT of potential to transversal disorder, and interesting crossover phenomena between LR and SR behavior. For isotropic polymers new effects (e.g. a sign change of zeta - zeta_0) result from the competition between localization and stretching by the flow. In contrast to purely potential disorder, where the dynamics gets frozen, here the dynamical exponent z is not much larger than 2, making it easily accessible by simulations. The phenomenon of pinning by transversal disorder is further demonstrated using a two monomer ``dumbbell'' toy model.

description: We propose a technique to develop (and localize in) topological maps from light detection and ranging (Lidar) data. Localizing an autonomous vehicle with respect to a reference map in real-time is crucial for its safe operation. Owing to the rich information provided by Lidar sensors, these are emerging as a promising choice for this task. However, since a Lidar outputs a large amount of data every fraction of a second, it is progressively harder to process the information in real-time. Consequently, current systems have migrated towards faster alternatives at the expense of accuracy. To overcome this inherent trade-off between latency and accuracy, we propose a technique to develop topological maps from Lidar data using the orthogonal Tucker3 tensor decomposition. Our experimental evaluations demonstrate that in addition to achieving a high compression ratio as compared to full data, the proposed technique, $\textit{TensorMap}$, also accurately detects the position of the vehicle in a graph-based representation of a map. We also analyze the robustness of the proposed technique to Gaussian and translational noise, thus initiating explorations into potential applications of tensor decompositions in Lidar data analysis.

Spinning up and down a Boltzmann gas

description: Using the average method, we derive a close set of linear equations that describes the spinning up of an harmonically trapped gas by a rotating anisotropy. We find explicit expressions for the needed to transfer angular momentum as well as the decay time induced by a static residual anisotropy. These different time scales are compared with the measured nucleation time and lifetime of vortices by the ENS group. We find a good agreement that may emphasize the role played by the non-condensed component in thoses experiments.

description: Wearable devices including accelerometers are increasingly being used to collect high-frequency human activity data in situ. There is tremendous potential to use such data to inform medical decision making and public health policies. However, modeling such data is challenging as they are high-dimensional, heterogeneous, and subject to informative missingness, e.g., zero readings when the device is removed by the participant. We propose a flexible and extensible continuous-time hidden Markov model to extract meaningful activity patterns from human accelerometer data. To facilitate estimation with massive data we derive an efficient learning algorithm that exploits the hierarchical structure of the parameters indexing the proposed model. We also propose a bootstrap procedure for interval estimation. The proposed methods are illustrated using data from the 2003 - 2004 and 2005 - 2006 National Health and Nutrition Examination Survey.

description: We describe the construction of a conserved reaction-diffusion system that exhibits self-organized critical (avalanche-like) behavior under the action of a slow addition of particles. The model provides an illustration of the general mechanism to generate self-organized criticality in conserving systems. Extensive simulations in d=2 and 3 reveal critical exponents compatible with the universality class of the stochastic Manna sandpile model.

$μ\to eγ$ Decay in the Left-Right Supersymmetric Model

description: We calculate the rate of the decay $μ\to eγ$ and the electric dipole moment of the electron in the left-right supersymmetric model when the breaking of parity occurs at a considerably large scale. The low-energy flavor violation in the model originates either from the nonvanishing remnants of the left-right symmetry in the slepton mass matrix or from the direct flavor changing lepton-slepton-neutralino interaction. The result is found to be large for the masses of the supersymmetric particles not far from the electroweak scale and already accessible at the current experimental accuracy. It also provides nontrivial constraints of the lepton mixing in the model.

description: The halo masses $M_{halo}$ of low surface brightness (LSB) galaxies are critical measurements for understanding their formation processes. One promising method to estimate a galaxy's $M_{halo}$ is to exploit the empirical scaling relation between $M_{halo}$ and the number of associated globular clusters ($N_{\mathrm{GC}}$). We use a Bayesian mixture model approach to measure $N_{\mathrm{GC}}$ for 175 LSB ($23\leq\left\langle μ_{e,r} \right\rangle [\mathrm{mag\ arcsec}^{-2}]\leq 28$) galaxies in the Fornax cluster using the Fornax Deep Survey (FDS) data; this is the largest sample of low mass galaxies so-far analysed for this kind of study. The proximity of the Fornax cluster means that we can measure galaxies with much smaller physical sizes ($0.3\leq r_{e,r}\ [\mathrm{kpc}]\leq 9.5$) compared to previous studies of the GC systems of LSB galaxies, probing stellar masses down to $M_{*}\sim10^{5}\mathrm{M_{\odot}}$. The sample also includes \nudg\ ultra-diffuse galaxies (UDGs), with projected $r$-band half-light radii greater than 1.5 kpc. Our results are consistent with an extrapolation of the $M_{*}-M_{halo}$ relation predicted from abundance matching. In particular, our UDG measurements are consistent with dwarf sized halos, having typical masses between $10^{10}$ and $10^{11}\mathrm{M_{\odot}}$. Overall, our UDG sample is statistically indistinguishable from smaller LSB galaxies in the same magnitude range. We do not find any candidates likely to be as rich as some of those found in the Coma cluster. We suggest that environment might play a role in producing GC-rich LSB galaxies.
