description: Using concave rectangular patches, a new solution to reduce mutual coupling and return loss in two-dimensional array of microstrip antennas is proposed. The effect of width and length concavity on mutual coupling and return loss is studied. Also, the patch parameters as well as the amounts of width and length concavity are optimized using an enhanced genetic algorithm. Simulation results show that the resulting array antenna has low amounts of mutual coupling and return loss.

Choline nutrition, choline status, and developmental outcome in early childhood
Creators: name: Wu, Brian Tid-Fung
Publisher: name: University of British Columbia
Year: 2014

description: Choline is an essential dietary nutrient that plays a key role as one of the few sources of methyl donors in the diet. Additional roles include the neurotransmitter acetylcholine and lipids such as phosphatidylcholine and sphingomyelin. Studies in adults have shown that choline deficiency results in fatty liver. In developing animals, choline deficiency also leads to impaired neural development. Despite the importance of choline as a nutrient, there is limited data on dietary intake in relation to needs, or dietary choline and its connection to human development. This project aims to determine the choline intake and plasma status of choline among children 5 years and 9 months of age, and to explore the relationship plasma free choline and its metabolites and cognitive development. This study includes a cross-sectional study with a total of 200 children at 5 years and 9 months of age. Dietary intake was collected by FFQ, 3x24 hr recalls and 1x24 hr recall. Dietary choline intake was estimated using USDA database. Venous blood was collected and plasma free choline, betaine, dimethylglycine, homocysteine, methionine and cysteine were analyzed using LC-MS/MS, and plasma tB12 and folate were analyzed using microparticle enzyme immunoassay and ion capture assay, respectively. Cognitive development was evaluated using KABC-II, PPVT-4, and Beery-VIM. The median intakes of choline and betaine were 278 mg/d and 90.2 mg/d, respectively, when estimated using the FFQ. The mean±SD (IQR) for plasma free choline, betaine and dimethylglycine were 8.57±2.08 (7.20–9.60) µmol/L, 45.4±12.9 (37.0–53.1) µmol/L, and 3.26±0.95 (2.60–3.80) µmol/L, respectively. About 34% of the children consumed below the current DRI of 250 mg/d of choline. Significant positive association was found between dietary intake of choline and plasma free choline (r=0.198, P=0.014), but dietary intake of betaine was not related to plasma betaine (P=0.915). Plasma free choline was inversely associated with plasma homocysteine (P=0.013). No associations were found between plasma free choline, betaine or dimethylglycine and any of the cognitive test results (P>0.05). An inverse relationship between plasma free choline and homocysteine might indicate the presence of choline deficiency in the children in this study.

description: Conjectures of Suciu relate the fundamental group of the complement M = C^n\A of a hyperplane arrangement A to the first resonance variety of H^*(M,Z). We describe a connection between the first resonance variety and the Orlik-Terao algebra C(A) of the arrangement. In particular, we show that non-local components of R^1(A) give rise to determinantal syzygies of C(A). As a result, Proj(C(A)) lies on a scroll, placing geometric constraints on R^1(A). The key observation is that C(A) is the homogeneous coordinate ring associated to a nef but not ample divisor on the blowup of P^2 at the singular points of A.

description: Decoherence represents a major obstacle towards realizing reliable quantum technologies. Identifying states that can be uphold against decoherence by purely coherent means, i.e., {\it stabilizable states}, for which the dissipation-induced decay can be completely compensated by suitable control Hamiltonians, can help to optimize the exploitation of fragile quantum resources and to understand the ultimate limits of coherent control for this purpose. In this work, we develop conditions for stabilizability based on the target state's eigendecomposition, both for general density operators and for the covariance matrix parameterization of Gaussian states. Unlike previous conditions for stabilizability, these spectral conditions are both necessary and sufficient and are typically easier to use, extending their scope of applicability. To demonstrate its viability, we use the spectral approach to derive upper bounds on stabilizability for a number of exemplary open system scenarios, including stabilization of generalized GHZ and W states in the presence of local dissipation and stabilization of squeezed thermal states under collective damping.

description: Two types of long range interactions, dipolar interaction and cavity-mediated interaction lead to exotic quantum phases. Both interactions have been realized and observed in optical lattice setups. Here, we study quantum phases of dipolar bosons trapped in optical lattices and coupled to a high-finesse cavity where both dipolar interaction and cavity-mediated interaction coexist. We perform quantum Monte Carlo simulations, and find that the checkerboard solid is enhanced and the checkerboard supersolid phase can exist in a wide range of densities (e.g. $ 0.27\lesssim n\lesssim0.73 $). Our unbiased numerical results suggest that both solid and supersolid phases can be achieved experimentally with magnetic atoms coupled to a cavity.

description: We extend molecular bootstrap embedding to make it appropriate for implementation on a quantum computer. This enables solution of the electronic structure problem of a large molecule as an optimization problem for a composite Lagrangian governing fragments of the total system, in such a way that fragment solutions can harness the capabilities of quantum computers. By employing state-of-art quantum subroutines including the quantum SWAP test and quantum amplitude amplification, we show how a quadratic speedup can be obtained over the classical algorithm, in principle. Utilization of quantum computation also allows the algorithm to match -- at little additional computational cost -- full density matrices at fragment boundaries, instead of being limited to 1-RDMs. Current quantum computers are small, but quantum bootstrap embedding provides a potentially generalizable strategy for harnessing such small machines through quantum fragment matching.

description: The interpretation of the charged (CCQE) and neutral (NCE) current quasi elastic events collected by the MiniBooNE collaboration involves a number of unresolved issues. While it has been suggested that the data can be explained in terms of an effective nucleon axial mass, $M_A$, the results of our theoretical calculations suggest that the CCQE and NCE samples cannot be described by the same value of $M_A$. We argue that the disagreement between theory and data may arise from the uncertainties associated with the flux average procedure. We also analyze the role of the strange quark in NCE interactions and find that, due to a cancellation between proton and neutron contributions, it turns out to be negligible.

description: This paper studies properties of simplicial complexes for which the m-th symbolic power of the Stanley-Reisner ideal equals to the m-th ordinary power for a given m > 1. The main results are combinatorial characterizations of such complexes in the two-dimensional case. It turns out that there exist only a finite number of complexes with this property and that these complexes can be described completely. As a consequence we are able to determine all complexes for which the m-th ordinary power of the Stanley-Reisner ideal is Cohen-Macaulay for a given m > 1.

description: We present the fingerprints of dynamic Jahn-Teller effect in resonant inelastic x-ray scattering (RIXS) spectra of K$_2$RuCl$_6$. We determined the dynamic Jahn-Teller model Hamiltonian of an embedded Ru$^{4+}$ ion using post Hartree-Fock methods, and derived the vibronic states by numerically diagonalizing the Hamiltonian. With the obtained vibronic states, we reproduced the RIXS spectra. The shape and the temperature dependence of the RIXS spectrum agree well with the experimental data. We found that some peaks emerge due to the dynamic Jahn-Teller effect rather than the crystal field splitting. Our study indicates the significance of the Jahn-Teller coupling to adequately interpret RIXS spectra.

Zwick (1982d) redescribed this species but eggs were unavailable at that time. Eggs from our specimens are ca. 0.35 mm long and ca. 0.20 mm wide in the equatorial zone. The collar is short, wide and the narrow rim is slightly flanged (Figs. 18‐19); collar width ca. 0.07 mm. Anchor mushroom shaped with marginal double row of globular bodies on small lobes (Fig. 20). Chorion with obscure, narrow striae extending from collar rim, ca. 12 visible in lateral aspect; area immediately adjacent to collar impunctate, but punctations become progressively more distinct distal to collar. Equatorial zone with slightly larger punctations than those on either side; lid completely punctate but most pits outline follicle cell impression walls and floors of most cells have few pits (Fig. 21). These eggs are similar to those of P.flaveola and P. flabellare (described above). They differ from the former in having more prominent striae, less conspicuous punctations on the lid and the equatorial zone has larger rather than smaller pits than the adjacent chorionic areas; they differ from eggs of the latter species in having more and slightly more prominent striae and in having much less conspicuous punctuation on the lid.

Image transmission over OFDM channel with rate allocation scheme and minimum peak-toaverage power ratio

Publisher: name: arXiv
Year: 2010
Subjects: subject: Networking and Internet Architecture (cs.NI)

description: This paper proposes new scheme for efficient rate allocation in conjunction with reducing peak-to-average power ratio (PAPR) in orthogonal frequency-division multiplexing (OFDM) systems. Modification of the set partitioning in hierarchical trees (SPIHT) image coder is proposed to generate four different groups of bit-stream relative to its significances. The significant bits, the sign bits, the set bits and the refinement bits are transmitted in four different groups. The proposed method for reducing the PAPR utilizes twice the unequal error protection (UEP), using the Read-Solomon codes (RS), in conjunction with bit-rate allocation and selective interleaving to provide minimum PAPR. The output bit-stream from the source code (SPIHT) will be started by the most significant types of bits (first group of bits). The optimal unequal error protection (UEP) of the four groups is proposed based on the channel destortion. The proposed structure provides significant improvement in bit error rate (BER) performance. Performed computer simulations have shown that the proposed scheme outperform the performance of most of the recent PAPR reduction techniques in most cases. Moreover, the simulation results indicate that the proposed scheme provides significantly better PSNR performance in comparison to well-known robust coding schemes.

Our approach follows the density-functional theory with the energy functional based on the exact Quantum Monte Carlo (QMC) simulations. Our model covers, but goes beyond, the popular approach with the Lee-Huang-Yang corrections. We first benchmark our approach against available QMC data in all interaction regimes and then study dynamical properties, inaccessible by ab initio many-body simulations. Our analysis includes a study of monopole modes and reveals the presence of anomalous dark solitons.

Data famine in big data era : machine learning algorithms for visual object recognition with limited training data
Creators: name: Guo, Zhenyu
Publisher: name: University of British Columbia
Year: 2014

description: Big data is an increasingly attractive concept in many fields both in academia and in industry. The increasing amount of information actually builds an illusion that we are going to have enough data to solve all the data driven problems. Unfortunately it is not true, especially for areas where machine learning methods are heavily employed, since sufficient high-quality training data doesn't necessarily come with the big data, and it is not easy or sometimes impossible to collect sufficient training samples, which most computational algorithms depend on. This thesis mainly focuses on dealing situations with limited training data in visual object recognition, by developing novel machine learning algorithms to overcome the limited training data difficulty. We investigate three issues in object recognition involving limited training data: 1. one-shot object recognition, 2. cross-domain object recognition, and 3. object recognition for images with different picture styles. For Issue 1, we propose an unsupervised feature learning algorithm by constructing a deep structure of the stacked Hierarchical Dirichlet Process (HDP) auto-encoder, in order to extract "semantic" information from unlabeled source images. For Issue 2, we propose a Domain Adaptive Input-Output Kernel Learning algorithm to reduce the domain shifts in both input and output spaces. For Issue 3, we introduce a new problem involving images with different picture styles, successfully formulate the relationship between pixel mapping functions with gradient based image descriptors, and also propose a multiple kernel based algorithm to learn an optimal combination of basis pixel mapping functions to improve the recognition accuracy. For all the proposed algorithms, experimental results on publicly available data sets demonstrate the performance improvements over previous state-of-arts.

description: We study the linear syzygies of a homogeneous ideal I in a polynomial ring S, focusing on the graded betti numbers b_(i,i+1) = dim_k Tor_i(S/I, k)_(i+1). For a variety X and divisor D with S = Sym(H^0(D)*), what conditions on D ensure that b_(i,i+1) is nonzero? Eisenbud has shown that a decomposition D = A + B such that A and B have at least two sections gives rise to determinantal equations (and corresponding syzygies) in I_X; and conjectured that if I_2 is generated by quadrics of rank at most 4, then the last nonvanishing b_(i,i+1) is a consequence of such equations. We describe obstructions to this conjecture and prove a variant. The obstructions arise from toric specializations of the Rees algebra of Koszul cycles, and we give an explicit construction of toric varieties with minimal linear syzygies of arbitrarily high rank. This gives one answer to a question posed by Eisenbud and Koh about specializations of syzygies.

description: Abstract

This study examines how forensic auditing influences bank performance in Nigeria, using annual data from 2013 to 2023. By applying the autoregressive distributed lag (ARDL) model and validating the results with fully modified ordinary least squares (FMOLS), the study provides a comprehensive analysis of forensic auditing's impact on the banking sector. The findings reveal that forensic auditing plays a crucial role in enhancing financial reporting accuracy, fraud detection, and risk management. By minimizing fraudulent activities and ensuring compliance with regulatory standards, forensic auditing fosters a more secure and efficient banking environment. Additionally, the study underscores its role in restoring stakeholder confidence, as greater transparency and accountability lead to increased trust in financial institutions. Banks that integrate forensic auditing are better positioned to detect irregularities early, mitigate risks, and improve overall operational efficiency and profitability. Given these insights, the study recommends that banks enhance their Anti-Money Laundering (AML) mechanisms by adopting stronger forensic auditing frameworks. This proactive approach can help identify and prevent money laundering activities, ultimately safeguarding the integrity of Nigeria’s financial system.

description: We present an optimized algorithm for assigning fibers to targets in next-generation fiber-fed multi-object spectrographs. The method, that we named draining algorithm, ensures that the maximum number of targets in a given target field is observed in the first few tiles. Using randomly distributed targets and mock galaxy catalogs we have estimated that the gain provided by the draining algorithm as compared to a random assignment can be as much as 2% for the first tiles. This would imply for a survey like BigBOSS saving for observation several hundred thousand objects or, alternatively, reducing the covered area in ~350 sq. deg. An important advantage of this method is that the fiber collision problem can be solved easily and in an optimal way. We also discuss additional optimizations of the fiber positioning process. In particular, we show that allowing for rotation of the focal plane can improve the efficiency of the process in ~3.5-4.5% even if only small adjustments are permitted (up to 2 deg). For instruments that allow large rotations of the focal plane the expected gain increases to ~5-6%. These results, therefore, strongly support focal plane rotation in future spectrographs, as far as the efficiency of the fiber positioning process is concerned. Finally, we discuss on the implications of our optimizations and provide some basic hints for an optimal survey strategy based on the number of targets per positioner.

description: GRIPS is planned to be the next great satellite-born survey mission lead by Europe; it will look into the cosmos with unprecedented accuracy in several bands of the EM spectrum (infrared, X-rays, MeV gamma-rays); in particular in gamma-rays, GRIPS will be able to bridge the so-called MeV gap and to answer several questions brought forth by GeV-TeV gamma-ray observations. We will discuss here several connections to GeV-TeV gamma-ray astrophysics, focussing in particular to show how GRIPS will be crucial in revealing the origin of cosmic rays.

description: We investigate compact objects in modified teleparallel gravity with realistic equations of state. We propose a modification of Teleparallel Equivalent to General Relativity, then an appropriate tetrad is applied to the field equations. A specific set of relations showing an equivalency between our gravitational model and the New General Relativity is found. The conservation equation implies that our Tolman-Oppenheimer-Volkoff equations are presented with an effective gravitational coupling constant. Numerical analysis using realistic equations of state is made, and the behavior of mass, radius, and the relation mass-radius as functions of a free parameter of our model is also investigated.

description: CHERI-C extends the C programming language by adding hardware capabilities, ensuring a certain degree of memory safety while remaining efficient. Capabilities can also be employed for higher-level security measures, such as software compartmentalization, that have to be used correctly to achieve the desired security guarantees. As the extension changes the semantics of C, new theories and tooling are required to reason about CHERI-C code and verify correctness. In this work, we present a formal memory model that provides a memory semantics for CHERI-C programs. We present a generalised theory with rich properties suitable for verification and potentially other types of analyses. Our theory is backed by an Isabelle/HOL formalisation that also generates an OCaml executable instance of the memory model. The verified and extracted code is then used to instantiate the parametric Gillian program analysis framework, with which we can perform concrete execution of CHERI-C programs. The tool can run a CHERI-C test suite, demonstrating the correctness of our tool, and catch a good class of safety violations that the CHERI hardware might miss.

description: In battery modeling, the electrode is discretized at the macroscopic scale with a single representative particle in each volume. This lacks the accurate physics to describe interparticle interactions in electrodes. To remedy this, we formulate a model that describes the evolution of degradation of a population of battery active material particles using ideas in population genetics of fitness evolution, where the state of a system depends on the health of each particle that contributes to the system. With the fitness formulation, the model incorporates effects of particle size and heterogeneous degradation effects which accumulate in the particles as the battery is cycled, accounting for different active material degradation mechanisms. At the particle scale, degradation progresses nonuniformly across the population of active particles, observed from the autocatalytic relationship between fitness and degradation. Electrode-level degradation is formed from various contributions of the particle-level degradation, especially from smaller particles. It is shown that specific mechanisms of particle-level degradation can be associated with characteristic signatures in the capacity-loss and voltage profiles. Conversely, certain features in the electrode-level phenomena can also provide insight into the relative importance of different particle-level degradation mechanisms.
Enzyme-substrate interactions and their influence on enzyme recycling strategies as a way of reusing cellulases

description: Relatively high enzyme loadings are required for the bioconversion of lignocellulosic biomass, impeding the economical production of cellulosic sugars. The relative stability and robustness of these enzymes make enzyme recycling an attractive cost-reduction strategy. However, the efficiency of enzyme recycling has been limited by the complexity of enzyme-substrate interactions, which are influenced by enzyme, substrate, and physical factors. A lack of techniques to probe specific enzyme adsorption further limits our understanding of these interactions. Therefore, overcoming these challenges to better understand enzyme-substrate interactions is crucial if we are to improve the effectiveness of enzyme recycling strategies. Initial work compared various ways to assess enzyme adsorption during hydrolysis of steam pretreated corn stover (SPCS) using a complete commercial cellulase mixture. While the distribution of six individual enzymes could be followed, the initial approach used was laborious, highlighting the limitations of techniques used to quantify individual enzyme adsorption profiles. A quicker, more sensitive double antibody sandwich enzyme-linked immunosorbent assay (ELISA) was subsequently developed, to follow Cel7A, Cel6A, and Cel7B adsorption during hydrolysis, and shown to agree with earlier results. As enzyme, substrate, and physical factors were known to affect enzyme recycling performance, their influence on individual enzyme adsorption was evaluated. Although the lignin present in the SPCS did not appear to influence enzyme adsorption (although Cel6A adsorbed more readily to the lignin-containing SPCS), cellulose allomorphs and crystallinity did appear to influence enzyme adsorption. The addition of Auxiliary Activity (AA) family 9, an oxidative enzyme, increased desorption of Cel7A, likely by increasing the substrate’s negative charge. The AA9 itself remained primarily in the supernatant, which highlighted the importance of recovering enzymes from both the liquid and solid phases of the reaction. The influence of glucose and ethanol on enzyme adsorption was evaluated, and a reduction in enzyme adsorption was observed at high glucose but not ethanol concentrations. When the addition of fresh substrate was assessed as one way to recover enzymes, by combining enzyme recycling at low glucose concentrations with enzyme supplementation, good overall cellulose hydrolysis (~70%) over 5 rounds of enzyme recycle could be achieved with a 50% reduction in enzyme loading.

Electroweak Sphaleron in a Magnetic field

description: Using lattice simulations we calculate the rate of baryon number violating processes, the sphaleron rate, in the Standard Model with an external (hyper)magnetic field for temperatures across the electroweak cross-over, focusing on the broken phase. Additionally, we compute the Higgs expectation value and the pseudocritical temperature. The electroweak cross-over shifts to lower temperatures with increasing external magnetic field, bringing the onset of the suppression of the baryon number violation with it. When the hypermagnetic field reaches the magitude $B_Y \approx 2 T^2$ the cross-over temperature is reduced from $160$ GeV to $145$ GeV. In the broken phase for small magnetic fields the rate behaves quadratically as a function of the magnetic flux. For stronger magnetic fields the rate reaches a linear regime which lasts until the field gets strong enough to restore the electroweak symmetry where the symmetric phase rate is reached.

description: A novel framework to enhance the angular resolution of automotive radars is proposed. An approach to enlarge the antenna aperture using artificial neural networks is developed using a self-supervised learning scheme. Data from a high angular resolution radar, i.e., a radar with a large antenna aperture, is used to train a deep neural network to extrapolate the antenna element's response. Afterward, the trained network is used to enhance the angular resolution of compact, low-cost radars. One million scenarios are simulated in a Monte-Carlo fashion, varying the number of targets, their Radar Cross Section (RCS), and location to evaluate the method's performance. Finally, the method is tested in real automotive data collected outdoors with a commercial radar system. A significant increase in the ability to resolve targets is demonstrated, which can translate to more accurate and faster responses from the planning and decision making system of the vehicle.

The importance of tight $f$ basis functions for heavy p-block oxides and halides: a parallel with tight $d$ functions in the second row

description: It is well-known that both wavefunction ab initio and DFT calculations on second-row compounds exhibit anomalously slow basis set convergence unless the basis sets are augmented with additional `tight' (high-exponent) $d$ functions, as in the cc-pV($n+d$)Z and aug-cc-pV($n+d$)Z basis sets. This has been rationalized as being necessary for a better description of the low-lying $3d$ orbital, which as the oxidation state increases sinks low enough to act as a back-donation acceptor from chalcogen and halogen lone pairs. This prompts the question whether a similar phenomenon exists for the isovalent compounds of the heavy p-block. We show that for the fourth and fifth row, this is the case, but this time for tight $f$ functions enhancing the description of the low-lying $4f$ and $5f$ Rydberg orbitals, respectively. In the third-row heavy $p$ block, the $4f$ orbitals are too far up, while the $4d$ orbitals are adequately covered by the basis functions already present to describe the $3d$ subvalence orbitals.

description: The nonbaryonic dark matter of the Universe is assumed to consist of new stable particles. A specific case is possible, when new stable particles bear ordinary electric charge and bind in heavy "atoms" by ordinary Coulomb interaction. Such possibility is severely restricted by the constraints on anomalous isotopes of light elements that form positively charged heavy species with ordinary electrons. The trouble is avoided, if stable particles $X^{--}$ with charge -2 are in excess over their antiparticles (with charge +2) and there are no stable particles with charges +1 and -1. Then primordial helium, formed in Big Bang Nucleosynthesis, captures all $X^{--}$ in neutral "atoms" of O-helium (OHe), thus creating a specific Warmer than Cold nuclear-interacting composite dark matter. Slowed down in the terrestrial matter, OHe is elusive for direct methods of underground dark. However OHe-nucleus interaction leads to their binding and in OHe-Na system the energy of such level can be in the interval of energy 2-4 keV. It explains the results of DAMA/NaI and DAMA/LIBRA experiments. The puzzles of direct dark matter searches appear in this solution as a reflection of nontrivial nuclear physics of OHe. (abridged)
