description: Flowering time in wheat is regulated mainly by response to seasonal environmental cues and controlled by the photoperiod and vernalization pathways.  Allelic diversity in genes controlling these pathways is used by breeders to adapt wheat for optimal yield in a broad range of environments.  This study characterized genetic loci influencing heading date in a soft red winter wheat doubled haploid population.  Two photoperiod insensitivity alleles, Ppd-A1a and Ppd-D1a, were found to have major effects in eight field locations.  The Ppd-A1 locus explained up to 16.8% of variation in heading date, whereas the Ppd-D1 locus explained up to 39.7%.  In reduced vernalization greenhouse experiments, a QTL in the same region as the VRN-A1 gene explained up to 42.4% of variation in heading date, suggesting that the population differed in this region.  Assays for previously-described allelic diversity in the VRN-A1 gene, however, did not detect any polymorphism between parents of the population.
A triangle of dualities: reversibly decomposable quantum channels, source-channel duality, and time reversal

description: Two quantum information processing protocols are said to be dual under resource reversal if the resources consumed (generated) in one protocol are generated (consumed) in the other. Previously known examples include the duality between entanglement concentration and dilution, and the duality between coherent versions of teleportation and super-dense coding. A quantum feedback channel is an isometry from a system belonging to Alice to a system shared between Alice and Bob. We show that such a resource may be reversibly decomposed into a perfect quantum channel and pure entanglement, generalizing both of the above examples. The dual protocols responsible for this decomposition are the ``feedback father'' (FF) protocol and the ``fully quantum reverse Shannon'' (FQRS) protocol. Moreover, the ``fully quantum Slepian-Wolf'' protocol (FQSW), a generalization of the recently discovered ``quantum state merging'', is related to FF by source-channel duality, and to FQRS by time reversal duality, thus forming a triangle of dualities. The source-channel duality is identified as the origin of the previously poorly understood ``mother-father'' duality. Due to a symmetry breaking, the dualities extend only partially to classical information theory.

description: UV photoinduced fragmentation of protonated aromatics amino acids have emerged the last few years, coming from a situation where nothing was known to what we think a good understanding of the optical properties. We will mainly focus this review on the tryptophan case. Three groups have mostly done spectroscopic studies and one has mainly been involved in dynamics studies of the excited states in the femtosecond/picosecond range and also in the fragmentation kinetics from nanosecond to millisecond. All these data, along with high level ab initio calculations, have shed light on the role of the different electronic states of the protonated molecules upon the fragmentation mechanisms.

description: By analogy with algebraic geometry, we define a category of non-linear sheaves (quasi-coherent homotopy-sheaves of topological spaces) on projective toric varieties and prove a splitting result for its algebraic K-theory, generalising earlier results for projective spaces. The splitting is expressed in terms of the number of interior lattice points of dilations of a polytope associated to the variety. The proof uses combinatorial and geometrical results on polytopal complexes. The same methods also give an elementary explicit calculation of the cohomology groups of a projective toric variety over any commutative ring.

description: A model for an expanding noncommutative acoustic fluid analogous to a Friedmann-Robertson-Walker geometry is derived. For this purpose, a noncommutative Abelian Higgs model is considered in a (3+1)-dimensional spacetime. In this scenario, we analyze the motion of test particles in this fluid. The study considers a scalar test particle coupled to a quantized fluctuating massless scalar field. For all cases studied, we find corrections due to the noncommutativity in the mean squared velocity of the particles. The nonzero velocity dispersion for particles that are free to move on geodesics disagrees with the null result found previously in the literature for expanding commutative fluid.

description: Algorithmic Cooling is a method that uses novel data compression techniques and simplecquantum computing devices to improve NMR spectroscopy, and to offer scalable NMR quantum computers. The algorithm recursively employs two steps. A reversible entropy compression of the computation quantum-bits (qubits) of the system and an irreversible heat transfer from the system to the environment through a set of reset qubits that reach thermal relaxation rapidly. Is it possible to experimentally demonstrate algorithmic cooling using existing technology? To allow experimental algorithmic cooling, the thermalization time of the reset qubits must be much shorter than the thermalization time of the computation qubits. However such thermalization-times ratios have yet to be reported. We investigate here the effect of a paramagnetic salt on the thermalization-times ratio of computation qubits (carbons) and a reset qubit (hydrogen). We show that the thermalization-times ratio is improved by approximately three-fold. Based on this result, an experimental demonstration of algorithmic cooling by thermalization and magnetic ions is currently performed by our group and collaborators.

ZONE MODELING OF VERY-LOW-FREQUENCY UNSTABLE BEHAVIOR IN MECHANICALLY-VENTILATED COMPARTMENT FIRES
Creators: name: Pi, Xiaoyue
Publisher: name: Digital Repository at the University of Maryland
Year: 2015
Subjects: subject: Mechanical engineering
subject: FOS: Mechanical engineering

description: A zone model is developed to simulate the oscillatory behavior occasionally observed in compartment fires. This oscillatory behavior is the result of an unstable coupling between the liquid fuel evaporation rate, the combustion process, the compartment pressure and the ventilation of the compartment. The governing equations use a classical zone modeling approach combined with a (N-τ) model description of the variations of the fuel evaporation rate. The equations are solved with an in-house Matlab solver. The model is evaluated by comparisons with experimental data previously obtained at Institut de Radioprotection et de Sûreté Nucléaire (IRSN) in France. Three different variations of the (N-τ) model are evaluated, corresponding to a coupling between liquid fuel evaporation and bulk oxygen, bulk temperature or admission flow rate. It is found that the variation corresponding to a coupling between liquid fuel evaporation and bulk oxygen provides the more realistic results.
A STUDY OF FEATURE SETS FOR EMOTION RECOGNITION FROM SPEECH SIGNALS

Year: 2015
Subjects: subject: Electrical engineering
subject: Emotion Recognition

description: This thesis focuses on finding useful features for emotion recognition from speech signals. In comparison to the popular openSMILE “emobase” feature set, our proposed method reduced the size of feature space to about 28% yet boosted the recognition rate by 3.3%.

Given we are at a point technologically where computing is cheap and fast, and lots of data are available, the approach to solving all sorts of problems is based on sophisticated machine learning techniques to implicitly make sense of data. Yet in this work, we study particular features that are felt to correlate with changes in emotion but have not been commonly selected for emotion recognition tasks. Jitter, shimmer, breathiness, and speaking rate are analyzed and are found to systematically change as a function of emotion.

We not only explore these additional acoustic features that help improve the classification performance, but also try to understand the importance of the existing features in improving accuracy. Our results show that using our features together with MFCCs and pitch related features lead to a better performance.

description: Crosslinking is an essential procedure for maintaining the integrity of protein-based nanoparticles, but the application of toxic crosslinkers is usually undesirable. In this study, a tyrosinase-aided crosslinking procedure was developed and compared to a conventional crosslinker (i.e. glutaraldehyde). Nanoparticles were firstly synthesized from sodium caseinate (SC) in both aqueous and alcoholic solvent systems. The particles were crosslinked by tyrosinase (alone or with added natural phenols) or glutaraldehyde and then examined for their integrity under simulated environmental stress, including pH variation and solvent evaporation. Under aqueous condition, SC nanoparticles were not crosslinked sufficiently by tyrosinase or phenols alone, despite the abundance of tyrosine residues in SC. Conversely, satisfying crosslinking was achieved by tyrosinase combined with two natural phenols (catechol or chlorogenic acid, both at 2.5 mol/mol protein), as evidenced by stable particle size and count rate under environmental stress. A higher dose of 7.5 mol/mol protein was required for glutaraldehyde to achieve a comparable efficacy. Upon introduction of alcohol, the efficacies for both glutaraldehyde and tyrosinase-phenol mixtures decreased, but glutaraldehyde required lower dose and exhibited more significant crosslinking for achieving same crosslinking efficiency. However, a considerable number of nanoparticles were detected by scanning electron microscopy with both crosslinkers. Overall, tyrosinase-aided oxidation is a competitive, low-toxicity approach for crosslinking protein nanoparticles.

description: Recently, contrastive learning (CL) has emerged as a successful method for unsupervised graph representation learning. Most graph CL methods first perform stochastic augmentation on the input graph to obtain two graph views and maximize the agreement of representations in the two views. Despite the prosperous development of graph CL methods, the design of graph augmentation schemes -- a crucial component in CL -- remains rarely explored. We argue that the data augmentation schemes should preserve intrinsic structures and attributes of graphs, which will force the model to learn representations that are insensitive to perturbation on unimportant nodes and edges. However, most existing methods adopt uniform data augmentation schemes, like uniformly dropping edges and uniformly shuffling features, leading to suboptimal performance. In this paper, we propose a novel graph contrastive representation learning method with adaptive augmentation that incorporates various priors for topological and semantic aspects of the graph. Specifically, on the topology level, we design augmentation schemes based on node centrality measures to highlight important connective structures. On the node attribute level, we corrupt node features by adding more noise to unimportant node features, to enforce the model to recognize underlying semantic information. We perform extensive experiments of node classification on a variety of real-world datasets. Experimental results demonstrate that our proposed method consistently outperforms existing state-of-the-art baselines and even surpasses some supervised counterparts, which validates the effectiveness of the proposed contrastive framework with adaptive augmentation.

description: Degenerative disc disease is commonly linked with low back pain, a major musculoskeletal disorder contributing to an annual socioeconomic impact of over $100 billion. The intervertebral disc (IVD) plays a critical role in spinal load bearing and many of the mechanisms of its degeneration are still unknown. This study focused on eliciting gene expression changes of the Nucleus Pulposus (NP), the inner region of the IVD critical to load support using an in vivo rat model. First, pneumatic artificial muscles (PAMs) were calibrated and integrated into a small loading device as an actuation mechanism. Next, various load histories were then applied on IVDs and gene expression was determined by qRT-PCR. Results show that discs with increased intradiscal pressure led increased expression of genes common to the NP. This study contributes to the better understanding of how load history alters IVD health and validates a device for future long term studies.

description: Using the similarity between spacetime torsion and axial gauge couplings, we study torsional contributions to the equilibrium partition function in a stationary background. In the case of a charged fluid minimally coupled to torsion, we spot the existence of linear torsional magnetic and vortical effects, while the axial-vector current and the spin energy potential do not receive corrections in the torsion at linear order. The covariant energy-momentum tensor, on the other hand, does contain terms linear in the torsion tensor. The case of a two-flavor hadronic superfluid is also analyzed, and the torsional contributions to the constitutive relations computed. Our results show the existence of a torsional electric chiral effect mediated by the charged pions.

A Simplified Model for Interconnect Stresses Induced by Bending of Printed Wiring Boards

Year: 2015
Subjects: subject: Mechanical engineering
subject: FOS: Mechanical engineering

subject: Rayleigh-Ritz Model

description: A simplified model is developed for analysis of interconnect stresses induced by changes in the curvature of printed wiring boards.  The model utilizes the Rayleigh-Ritz variational approach and can be used for rapid assessment and is well-suited for parametric studies because it does not need any numerical meshing.  This simplified model represents the component as an equivalent shell and the interconnects as deformable beams.  As a simplification, any initial warpage of the component has been neglected in this study.  Finite element models are used to verify the simplified model: a simplified FEA model that utilizes the same shell idealization as the proposed Rayleigh-Ritz model and a more detailed 3D solid model. The proposed simplified model provides a faster, more versatile alternative to FEA and can be used to estimate the interconnect stresses caused by PWB warpage under a variety of thermomechanical, vibration, and shock/drop loading conditions.

This thesis focuses on demonstrating the use of this simplified modeling approach for area array surface mount components (e.g. stud-grid array, land-grid array, column grid array, and ball grid array).  In particular, the example problem addressed in this thesis is the pre-stress induced in surface mount area-array interconnects during the solder reflow process used for attaching surface mount packages to printed wiring boards (PWBs).  The possibility exists for the PWB and component to warp during the reflow process and therefore exhibit some concave or convex curvature once the process has been completed.  If the PWB is then straightened during the assembly process, the act of straightening the PWB can cause pre-stresses to develop in the interconnects between the PWB and the component package.  It is important to understand these pre-stresses because unaccounted for interconnect pre-stresses can result in premature wear-out failures or unexpected overstress failures of the assembly.

description: A simulation study for the magnetization process is performed for the multi-domain state in a chiral p-wave superconductor, using the time-dependent Ginzburg-Landau theory. The external field penetrates inside as core-less vortices through the domain wall, forming the vortex sheet structure. We find that, with increasing magnetic fields, the domain walls move so that the unstable domains shrink to vanish. Therefore, the single domain structure is realized at higher fields.
County Effects on White-Collar Sentencing in Maryland Circuit Courts

description: Research on local contexts has been a major development within sentencing literature in recent years. White-collar sentencing, however, is an area that has not received much attention from local contexts research. The current study addresses that gap, estimating geographical effects on sentencing outcomes for a group of white-collar offenders in Maryland’s circuit courts using data from the Maryland State Commission on Criminal Sentencing Policy. The results show, consistent with local contexts research focused on conventional offenders, that the jurisdiction sentencing a white-collar defendant affects outcomes after controlling for a variety of individual-level case characteristics. The county effects this study finds, however, are not entirely consistent with what the local contexts of sentencing literature would predict for general offender sentencing. These findings, though limited, suggest that somewhat different dynamics may apply in the white-collar sentencing context, highlighting the need for further research in this area.

description: We present the first lattice QCD determination of the $Λ_b \to Λ^*(1520)$ vector, axial vector, and tensor form factors that are relevant for the rare decays $Λ_b \to Λ^*(1520)\ell^+\ell^-$. The lattice calculation is performed in the $Λ^*(1520)$ rest frame with nonzero $Λ_b$ momenta, and is limited to the high-$q^2$ region. An interpolating field with covariant derivatives is used to obtain good overlap with the $Λ^*(1520)$. The analysis treats the $Λ^*(1520)$ as a stable particle, which is expected to be a reasonable approximation for this narrow resonance. A domain-wall action is used for the light and strange quarks, while the $b$ quark is implemented with an anisotropic clover action with coefficients tuned to produce the correct $B_s$ kinetic mass, rest mass, and hyperfine splitting. We use three different ensembles of lattice gauge-field configurations generated by the RBC and UKQCD collaborations, and perform extrapolations of the form factors to the continuum limit and physical pion mass. We give Standard-Model predictions for the $Λ_b \to Λ^*(1520)\ell^+\ell^-$ differential branching fraction and angular observables in the high-$q^2$ region.

Robust sculpting using boundary represented solids

Publisher: name: University of British Columbia
Year: 2009

description: Boolean operations are often used in the computer modeling of 3-D mechanical parts and machineries and are known for their predictable behavior and ease of use. The use of Boolean operations in the interactive modeling of free-form models, however, has been rather limited. Some of the difficulties in realizing this include: selecting a model representation that may be displayed at interactive speed, applying Boolean operations robustly, and creating smooth surface transitions at the junctions between models. This thesis explores the use of the real number package of the Library of Efficient Datatypes and Algorithms (LEDA) for computing the Boolean combination of triangulated and boundary-represented solids robustly. This thesis also suggests a scheme for removing numerically unstable triangles which are detrimental to the validity of solids, and a surface blending scheme that simulates the smoothing of sharp surface junctions by modifying surface normals. Our scheme for computing Boolean operations is more robust than those used in two popular modeling applications but at the expense of longer computation time. Our scheme for removing numerically unstable triangles is effective in removing invalid surface triangulations while preserving the appearances of models and our simulated surface blending scheme is capable of smoothing non-trivial surface junctions at near-interactive rates. These features were implemented in a simple solid modeler and a set of models was created interactively using this system.

description: The economic value of energy storage to meet peak electricity demand is analyzed with an emphasis on the role of demand uncertainty. The concept of the stabilization value, which measures that part of the benefit of the storage project which is due solely to the stochastic demand components, is defined. The magnitude of the stabilization value, relative to the overall value of energy storage, is evaluated in terms of a simple model that accounts for the relevant characteristics of the electric power utility's production mix. It is found that neglecting the demand uncertainty can seriously bias the benefit assessment of the storage project as well as the determination of the optimal storage capacity.

description: The Alpha Magnetic Spectrometer (AMS) to be installed on the International Space Station (ISS) will be equipped with a proximity Ring Imaging Cherenkov (RICH) detector for measuring the velocity and electric charge of the charged cosmic particles. This detector will contribute to the high level of redundancy required for AMS as well as to the rejection of albedo particles. Charge separation up to iron and a velocity resolution of the order of 0.1% for singly charged particles are expected. A RICH protoptype consisting of a detection matrix with 96 photomultiplier units, a segment of a conical mirror and samples of the radiator materials was built and its performance was evaluated. Results from the last test beam performed with ion fragments resulting from the collision of a 158 GeV/c/nucleon primary beam of indium ions (CERN SPS) on a lead target are reported. The large amount of collected data allowed to test and characterize different aerogel samples and the sodium fluoride radiator. In addition, the reflectivity of the mirror was evaluated. The data analysis confirms the design goals.

In the second case, the experimental fission probability for excited 188Os is compared with the calculated one with Tc as a free parameter. It is concluded for both cases that the critical temperature is higher than 16 MeV.

A channel for educators to share lessons learned in these countries could benefit individuals preparing for assignments in foreign countries. Understanding the cultural and social differences in decision-making systems is critical to successful educational program development and implementation. Individuals in the emerging democracies often need training in management and market economics to apply at institutional as well as personal levels. Similar training for recipients of economic development funds could result in more effective application of funds.

The Z-scan measurements are recorded for both ZnO and ZnS with femtosecond laser pulses. While the wavelength dispersions of the Kerr nonlinearity are in agreement with a two-band model, the wavelength dependences of the 3PA are found to be given by (3Ephoton/Eg-1)5/2(3Ephoton/Eg)-9. We also evaluate higher-order nonlinear optical effects including the fifth-order instantaneous nonlinear refraction associated with virtual three-photon transitions, and effectively seventh-order nonlinear processes induced by three-photon-excited free charge carriers. These higher-order nonlinear effects are insignificant with laser excitation irradiances up to 40 GW/cm2. Both pump-probe measurements and three-photon figures of merits demonstrate that ZnO and ZnS should be a promising candidate for optical switching applications at telecommunication wavelengths.

description: We study the effects of final state interactions in the non-mesonic weak decay $ΛN \rightarrow nN$ (n is a neutron and N is either a neutron or a proton) of the hypernucleus $_Λ^4$He. Using a three-body model the effects of distortion of the interaction of the emitted nucleon pair with the residual nucleus is considered. We also study the influence of the final state interaction between the emitted nucleons using the Migdal-Watson model. The effect of spin symmetries in the final state of the pair is also considered. Based on our calculations, we conclude that final state interactions play a minor role in the kinetic energy spectrum of the emitted nucleon pair.

description: We investigate the impact of a common approximation on weak lensing power spectra: the use of single-epoch matter power spectra in integrals over redshift. We disentangle this from the closely connected Limber's approximation. We derive the unequal-time matter power spectrum at one-loop in standard perturbation theory and effective field theory to deal with non-linear physics. We compare these formalisms and conclude that the unequal-time power spectrum using effective field theory breaks for larger scales. As an alternative, we introduce the midpoint approximation. We also provide, for the first time, a fitting function for the time evolution of the effective field theory counterterms based on the Quijote simulations. Then we compute the angular power spectrum using a range of approaches: the Limber's approximation, and the geometric and midpoint approximations. We compare our results with the exact calculation at all angular scales using the unequal-time power spectrum. We use DES Y1 and LSST-like redshift distributions for our analysis. We find that the use of the Limber's approximation in weak lensing diverges from the exact calculation of the angular power spectrum on large-angle separations, $\ell < 10$. Even though this deviation is of order $2\%$ maximum for cosmic lensing, we find the biggest effect for galaxy clustering and galaxy-galaxy lensing. We show that not only is this true for upcoming galaxy surveys, but also for current data such as DES Y1. Finally, we make our pipeline and analysis publicly available as a Python package called unequalpy.

description: We estimate the influence of policy-induced price changes and of technology supply on North Carolina flue-cured tobacco yields. The decline in land rent and effective output price that accompanied a 1965 policy change from acreage allotments to poundage quotas caused a 12 percent decrease in yields. Farmer yields were more responsive to yield-increasing technologies under acreage allotments than under poundage quotas. Annual yield growth was 0.5 percent under poundage quotas and 4.32 percent under acreage allotments. The growth rate decline is attributable to changes in relative prices and to a slowdown in the supply of available technologies.
On the stability and accuracy of the Empirical Interpolation Method and Gravitational Wave Surrogates

description: The combination of the Reduced Basis and the Empirical Interpolation Method (EIM) approaches have produced outstanding results in many disciplines. In particular, in gravitational wave (GW) science these results range from building non-intrusive surrogate models for GWs to fast parameter estimation adding the use of Reduced Order Quadratures. These surrogates have the salient feature of being essentially indistinguishable from or very close to supercomputer simulations of the Einstein equations, but can be evaluated in the order of a milisecond per multipole mode on a standard laptop. In this article we clarify a common misperception of the EIM as originally introduced and used in practice in GW science. Namely, we prove that the EIM at each iteration chooses the interpolation nodes so as to make the related Vandermonde-type matrix as invertible as possible; not necessarily optimizing its conditioning or accuracy of the interpolant as is sometimes thought. In fact, we introduce two new variations of the EIM, nested as well, which do optimize with respect to conditioning and the Lebesgue constant, respectively, and compare them through numerical experiments with the original EIM using GWs. Our analyses and numerical results suggest a subtle relationship between solving for the original EIM, conditioning, and the Lebesgue constant, in consonance with active research in rigorous approximation theory and related fields.

description: The debate over privatizing and water markets has moved back and forth for decades between the "I" and the "We" perspectives. Rather than either/or, a balanced "I&We" view of water institutions is needed. West is meeting east in water law. Public interest needs must be satisfied in appropriate decision forums, but marketing may prove a social improvement when used as a supplement. Balancing an "I&We" institution involves establishing an acceptable or tolerable level of interference through judicious mixing of state, common and private property regimes. Third-party effects are eliminated as mutual gain arises in a variety of decision forums.

Local most-probable routes and classic-quantum correspondence in strong-field two-dimensional tunneling ionization

description: We study ionization of atoms in strong two-dimensional (2D) laser fields with various forms, numerically and analytically. We focus on the local most-probable tunneling routes (some specific electron trajectories) which are corresponding to the local maxima of photoelectron momentum distributions (PMDs). By making classic-quantum correspondence, we obtain a condition for these routes characterized by the electron position at the tunnel exit. With comparing the identified routes with the classical limit and the partial-decoupling approximation where it is assumed that tunneling is dominated by the main component of the 2D field, some semiclassical properties of 2D tunneling are addressed. The local maxima of PMD related to the local most-probable routes can be used as one of the preferred observables in ultrafast measurements.

description: In the American colonial era, Anglicans associated with the Church of England founded parishes and built churches throughout the colonies. After the Revolutionary War, many of these Anglicans refused any sort of loyalty toward the Church of England, and thus established the Episcopal Church. Early churches were often central within individual settlements and central to the lives of its inhabitants. Over the centuries, however, the Episcopal Church has migrated to the peripheries of communities and has diminished in importance to much of the populace. Over the last decade membership in the Episcopal Church has decreased by nearly twenty percent, despite progressive attempts by church leadership to evolve with an ever-changing society. Utilizing the canon and customs of the Church as a guide, this thesis will explore how the Episcopal Church can respond and relate to a diverse contemporary society while maintaining its rich history and traditions so vital to its tenets, and explores what role innovative architectural thinking can play to support that evolution.

Considering the topology of the network, both uniform and degree-dependent delays are studied during the contagion process. We find that the existence of time delay will enhance both outbreaks and prevalence of infectious diseases in the network.

description: It is widely held that disorder is essential to the existence of a finite interval of magnetic field in which the Hall conductance is quantized, i.e. for the existence of `plateaus' in the quantum Hall effect. Here, we show that the existence of a quasi-particle Wigner crystal results in the persistence of plateaus of finite extent even in the limit of vanishing disorder. Several experimentally detectable features that characterize the behavior in the zero disorder limit are also explored.

description: Morale and faculty development are closely related. The agricultural economics profession must decide what it is about. There is room to practice the principle of comparative advantage and allow a degree of specialization in teaching, extension, and research. To continue in the role of an applied discipline, there must also be an opportunity for the young professional to establish rapport with, and understanding of, the private sector and the policy-making arena. If that is to happen, there must be encouragement in the institutional setting and by faculty colleagues who respect the importance of investment in building rapport and in establishing credibility. If that environment is present, morale should be good and faculty development will occur.
