Open dynamics of entanglement in mesoscopic bosonic systems

description: A key issue in Quantum Information is finding an adequate description of mesoscopic systems that is simpler than full quantum formalism yet retains crucial information about non-classical phenomena like entanglement. In particular, the study of fully bosonic systems undergoing open evolution is of great importance for the advancement of photonic quantum computing and communication. In this paper, we propose a mesoscopic description of such systems based on boson number correlations. This description allows for tracking Markovian open evolution of entanglement of both non-Gaussian and Gaussian states and their sub-Poissonian statistics. It can be viewed as a generalization of the reduced state of the field formalism [Entropy 2019, 21(7), 705], which by itself does not contain information about entanglement. As our approach adopts the structure of the description of two particles in terms of first quantization, it allows for broad intuitive usage of known tools. Using the proposed formalism, we show the robustness of entanglement against low-temperature damping for four-mode bright squeezed vacuum state and beam-splitted single photon. We also present a generalization of the Mandel Q parameter. Building upon this, we show that the entanglement of the state obtained by beam splitting of a single occupied mode is fully inherited from sub-Poissonian statistics of the input state.

Genetic mapping of aggressiveness in Fusarium graminearum, causing Fusarium head blight in durum wheat
Creators: name: Zhang, Yishan
Publisher: name: University of British Columbia
Year: 2024

description: Fusarium graminearum, the predominant causal agent of Fusarium head blight (FHB) in cereal crops, impacts the Canadian wheat industry through reducing grade and yield, and seed contamination with mycotoxins. Depending on the type of mycotoxins produced by F. graminearum, strains can be classified into multiple chemotypes. 3-acetyl-deoxynivalenol (3ADON) and 15-acetyl-deoxynivalenol (15ADON) are the dominant chemotypes in North America. A highly virulent population of the 3ADON chemotype is becoming more prevalent in North America, compared to the historically dominant population which produces 15ADON, resulting in an increasing risk of FHB in the Canadian wheat growing regions. Therefore, decoding the genetic factors of aggressiveness and their evolution among field populations is crucial for studying the wheat-Fusarium interactions. This project aims to map quantitative trait loci (QTL) conferring aggressiveness in F. graminearum (Fg-QTL), using a bi-parental population Fg09 (n = 170) derived from a cross between a 15ADON isolate (Nit5) and a 3ADON isolate from Saskatchewan (SK1797). A high-density genetic map was constructed and aggressiveness on the durum cultivar Kronos was evaluated. Through pan-genome analysis of a Nested Association Mapping Population (FgNAM), previously constructed to reflect aggressiveness variations in North American field populations, an Fg-QTL was identified in a sub-telomeric co-occurring with a genomic region with high nucleotide diversity on chromosome 3. This Fg-QTL explained 8.18 % of the variance in the area under disease progress curve (AUDPC) values and contained 36 genes. Three candidate genes were detected as potentially associated with the observed phenotypic differences in aggressiveness, as they exclusively held nucleotide variants unique to high-aggressiveness strains. Two of the genes encode proteins with predicted functions, mic19 and FLA protein, provided promising targets for further validation of the genetic basis of F. graminearum aggressiveness on durum wheat.

description: We report our complete database of X-ray eclipse timings of the low mass X-ray binary EXO0748-676 observed by the Rossi X-Ray Timing Explorer (RXTE) satellite. As of this writing we have accumulated 443 full X-ray eclipses, 392 of which have been observed with the Proportional Counter Array on RXTE. These include both observations where an eclipse was specifically targeted and those eclipses found in the RXTE data archive. Eclipse cycle count has been maintained since the discovery of the EXO0748-676 system in February 1985. We describe our observing and analysis techniques for each eclipse and describe improvements we have made since the last compilation by Wolff et al. (2002). The principal result of this paper is the database containing the timing results from a seven-parameter fit to the X-ray light curve for each observed eclipse along with the associated errors in the fitted parameters. Based on the standard O-C analysis, EXO0748-676 has undergone four distinct orbital period epochs since its discovery. In addition, EXO0748-676 shows small-scale events in the O-C curve that are likely due to short-lived changes in the secondary star.

description: (Abridged) Classical Be stars occasionally transition from having a gaseous circumstellar disk (''Be phase'') to a state in which all observational evidence for the presence of these disks disappears (''normal B-star phase''). We present one of the most comprehensive spectropolarimetric views to date of such a transition for two Be stars, pi Aquarii and 60 Cygni. 60 Cyg's disk loss episode was characterized by a monotonic decrease in emission strength over a time-scale of 1000 days, consistent with the viscous time-scale of the disk, assuming alpha is 0.14. pi Aqr's disk loss was episodic in nature and occurred over a time-scale of 2440 days. An observed time lag between the behavior of the polarization and H-alpha in both stars indicates the disk clearing proceeded in an ''inside-out'' manner. We determine the position angle of the intrinsic polarization to be 166.7 +/- 0.1 degrees for pi Aqr and 107.7 +/- 0.4 degrees for 60 Cyg, and model the observed polarization during the quiescent diskless phase of each star to determine the interstellar polarization along the line of sight. Minor outbursts observed during the quiescent phase of each star shared similar lifetimes as those previously reported for mu Cen, suggesting that the outbursts represent the injection and subsequent viscous dissipation of individual blobs of material into the inner circumstellar environments of these stars. We also observe deviations from the mean intrinsic polarization position angle during polarization outbursts in each star, indicating deviations from axisymmetry. We propose that these deviations might be indicative of the injection (and subsequent circularization) of new blobs into the inner disk, either in the plane of the bulk of the disk material or in a slightly inclined (non-coplanar) orbit.

description: A modified fluctuation-dissipation-theorem (MFDT) for a non-equilibrium steady state (NESS) is experimentally checked by studying the position fluctuations of a colloidal particle whose motion is confined in a toroidal optical trap. The NESS is generated by means of a rotating laser beam which exerts on the particle a sinusoidal conservative force plus a constant non-conservative one. The MFDT is shown to be perfectly verified by the experimental data. It can be interpreted as an equilibrium-like fluctuation-dissipation relation in the Lagrangian frame of the mean local velocity of the particle.

description: The reionization of the second electron of helium (HeII) leaves important imprints on the thermal and ionization state of the intergalactic medium (IGM). Observational evidence suggests that HeII reionization ended at $z \simeq 3$ due to ionizing photons emitted predominantly by quasars. We present efficient semi-numerical simulations of helium reionization in a $230 \ \mathrm{h^{-1}~Mpc}$ box, that takes into account the spatial patchiness of reionization coupled with photoheating of the IGM. Dark matter haloes are assigned quasars using empirical measurements of the quasar luminosity function, assuming a universal quasar lifetime consistent with duty cycle values inferred from measurements of the quasar clustering. The ionizing photon field from quasars is then included in the semi-numerical Code for ReionIzation with PhoTon conservation (SCRIPT), which was originally developed for modeling hydrogen reionization. In this work, we make appropriate modifications to SCRIPT for modeling inhomogenous HeII reionization and the corresponding thermal history of the IGM is modelled via a subgrid prescription. Our model has three main free parameters i.e. the global clumping factor $\mathcal{C}_{HeIII}$, the temperature increase due to photoheating $T^{re}_{He}$ and the quasar spectral energy distribution (SED) index, $α_{UV}$. Our fiducial model with $\mathcal{C}_{HeIII}=15.6$ and $T^{re}_{He} \sim 6000 \ K$ gives reasonable values for the empirical measurements of the temperature density equation of state at these redshifts, assuming that quasars brighter than $\mathrm{M_{1450}}<-21$ and having $α_{UV}=1.7$ contribute to HeII reionization. The efficiency of our code shows promising prospects for performing parameter estimation in future, for models of HeII reionization using observations of the Ly$α$ forest.

By using a finite element method for three-dimensional anisotropic heat transfer, we have simulated the heat conduction and temperature variations of a single nanotube, a nanotube array and a part of nanotube-based composite surface with heat generation. The thermal conductivity used is obtained from the upscaled value from the molecular simulations or experiments. Simulations show that nanotube arrays have unique cooling characteristics due to its anisotropic thermal conductivity.

Improving white spruce genome annotation and generation of a chromosome-scale epigenetic map
Creators: name: Yucel, Irem
Publisher: name: University of British Columbia
Year: 2024

description: White spruce (Picea glauca; Pinaceae) is a conifer native to the northern temperate and boreal forests of North America. It is a resilient tree that tolerates variations in climatic conditions. As a result, it is often used as a model for studying the genetic makeup and adaptability of conifer trees. A previous genome assembly of P. glauca, generated using short- and linked-read sequencing data, had over 2.4 million scaffolds with an NG50 length (a measure of assembly contiguity indicating that at least half of the expected genome size is in pieces at least the NG50 length) of 131 kb. Here I produce and report on an improved assembly of P. glauca, built using long nanopore sequencing reads and scaffolded with linked-read sequencing data, which represents one of the most contiguous (NG50 length = 2.3 Mbp) and gene-complete (56.1% complete BUSCO genes in the Embryophyta lineage) genomes of this size (~20 Gb). The new assembly was annotated using BRAKER2, which predicted 68,796 genes with a mean length of 18 kb. Repeat masking demonstrates that approximately 90% of the white spruce genome consists of repeat sequences, the majority of which are long terminal repeats (LTRs). Among other sequenced conifer species, phylogenetic analysis finds the closest relative of the white spruce to be interior, Engelmann and Sitka spruces. Orthogroup analysis recovered 2,024 genes found only in white spruce and not in other spruce or pines I analyzed. These genes are enriched in Gene Ontology (GO) terms related to biotic and abiotic stress responses. I used epigenetic information inherent in the long-read sequencing data to conduct a methylome analysis using NanoMethPhase. Using this, I identified a total of 320,946,144 CpG sites and 12,698 quality-filtered allelic differentially methylated regions (DMRs) for the genome. A total number of 1,930 of the annotated genes intersect with these allelic DMRs and this overlapping subset if enriched with GO terms related to plant responses to external damage and pathogen infection. The updated white spruce genome assembly with its detailed annotation and epigenetic map described here provides a valuable resource for furthering conifer research.

description: Splitting probabilities quantify the likelihood of a given outcome out of competitive events. This key observable of random walk theory, historically introduced as the gambler's ruin problem, is well understood for memoryless (Markovian) processes. However, in complex systems such as polymer fluids, the motion of a particle should typically be described as a process with memory, for which splitting probabilities are much less characterized analytically. Here, we introduce an analytical approach that provides the splitting probabilities for one-dimensional isotropic non-Markovian Gaussian processes with stationary increments, in the case of two targets. This analysis shows that splitting probabilities are controlled by the out of equilibrium trajectories observed after the first passage. This is directly evidenced in a prototypical experimental reaction scheme in viscoelastic fluids. These results are extended to $d$-dimensional processes in large confining volumes, opening a path towards the study of competitive events in complex media.

description: The γd \to K^+K^-pn reaction has been studied to search for the evidence of the Θ^+ by detecting K^+K^- pairs at forward angles. The Fermi-motion corrected nK^+ invariant mass distribution shows a narrow peak at 1.524 +- 0.002 + 0.003 GeV/c^2. The statistical significance of the peak calculated from a shape analysis is 5.1 σ, and the differential cross-section for the γn \to K^- Θ^+ reaction is estimated to be 12 +- 2 nb/sr in the photon energy range from 2.0 GeV to 2.4 GeV in the LEPS angular range by assuming the isotropic production of the Θ^+ in the γn center-of-mass system. The obtained results support the existence of the Θ^+.

description: Standard modern machine-learning-based imaging methods have faced challenges in medical applications due to the high cost of dataset construction and, thereby, the limited labeled training data available. Additionally, upon deployment, these methods are usually used to process a large volume of data on a daily basis, imposing a high maintenance cost on medical facilities. In this paper, we introduce a new neural network architecture, termed LoGoNet, with a tailored self-supervised learning (SSL) method to mitigate such challenges. LoGoNet integrates a novel feature extractor within a U-shaped architecture, leveraging Large Kernel Attention (LKA) and a dual encoding strategy to capture both long-range and short-range feature dependencies adeptly. This is in contrast to existing methods that rely on increasing network capacity to enhance feature extraction. This combination of novel techniques in our model is especially beneficial in medical image segmentation, given the difficulty of learning intricate and often irregular body organ shapes, such as the spleen. Complementary, we propose a novel SSL method tailored for 3D images to compensate for the lack of large labeled datasets. The method combines masking and contrastive learning techniques within a multi-task learning framework and is compatible with both Vision Transformer (ViT) and CNN-based models. We demonstrate the efficacy of our methods in numerous tasks across two standard datasets (i.e., BTCV and MSD). Benchmark comparisons with eight state-of-the-art models highlight LoGoNet's superior performance in both inference time and accuracy.

We compare the data from two different stations at the summit considering the accuracy of both instruments. We analysed the diurnal, seasonal and annual cycles for all the parameters. The thermal stability is remarkably good, crucial for a good performance of the telescopes. From the solar radiation data we developed a new method to estimate the fraction of time when the sky is clear of clouds. We show that our measurements are consistent with a warm standard atmosphere model. The conditions at the site are benign and stable given its altitude, showing that Sierra Negra is a extremely good site for millimeter and high energy observations.

Crystallographic and biochemical characterization of key steps in reductasporine and capuramycin biosynthesis

description: Studying individual biosynthetic transformations in the creation of natural products often reveals surprising and powerful chemical reactivities and molecular handling strategies. Indolocarbazole bisindoles have been widely tested in clinical studies and arise from oxidative dimerization of L-tryptophan. Among bisindoles, reductasporine bears an unusual dimethylpyrrolinium structure. Its biosynthesis differs from other indolocarbazole pathways by two tailoring enzymes: the imine reductase RedE and N,N-dimethyltransferase RedM. Here I reconstitute this pathway in vitro and show that RedE prevents unstable indolocarbazole intermediates from becoming oxidized and provides reduced didemethylreductasporine substrate to RedM. Employing X-ray crystallography, I solved two ternary complexes of RedE co-crystallized with the substrate-mimic arcyriaflavin A, revealing an extended active site cleft with distinct secondary indolocarbazole binding site. Site-directed mutagenesis confirms the conserved active site aspartate (D168) is essential for activity and anchors the substrate via hydrogen-bonding. Variants targeting the secondary binding site reduce catalytic efficiency, suggesting this site protects the substrate from autooxidation. I solved the 1.7 Å structure of RedM demonstrating it adopts distinct open and closed conformations with either SAH or SAM cofactor, respectively. Site-directed mutagenesis, docking and sequence bioinformatics identify conserved substrate-recognizing residues and suggest dimethyltransferase catalytic activity likely arises from precise orientation and desolvation of the substrate. Recently, Cap15 has been shown to be an oxygen- and pyridoxal phosphate (PLP)-dependent enzyme and is the first example of this activity in the L-seryl-tRNA(Sec) selenium transferase enzyme family. It catalyzes oxidative-decarboxylation of 5ʹ-glycyl uridine to the corresponding 5ʹ-carboxamide uridine. Solving for the 2.40 Å resolution crystal structure of Cap15 shows PLP bonds to K230 and a phosphate anion in the active site bridges N- and C-terminal domains. Sequence analysis reveals the loop proximal to the internal aldimine and hydrogen bonding to the active site phosphate is strictly conserved among Cap15 homologues present in capuramycin-type gene clusters. The crystal structures provide a basis for further investigations into the sequence-determinants of secondary binding site formation in RedE, dimethylation activity in RedM and oxygen-consuming activity in Cap15. RedE in particular can serve as a starting-point in the engineering of imine reductases to accommodate large substrates in the production of industry-relevant chiral amines.

description: The majority of galaxy mergers are expected to be minor mergers. The observational signatures of minor mergers are not well understood, thus there exist few constraints on the minor merger rate. This paper seeks to address this gap in our understanding by determining if and when minor mergers exhibit disturbed morphologies and how they differ from the morphology of major mergers. We simulate a series of unequal-mass moderate gas-fraction disc galaxy mergers. With the resulting g-band images, we determine how the time-scale for identifying galaxy mergers via projected separation and quantitative morphology (the Gini coefficient G, asymmetry A, and the second-order moment of the brightest 20% of the light M20) depends on the merger mass ratio, relative orientations and orbital parameters. We find that G-M20 is as sensitive to 9:1 baryonic mass ratio mergers as 1:1 mergers, with observability time-scales ~ 0.2-0.4 Gyr. In contrast, asymmetry finds mergers with baryonic mass ratios between 4:1 and 1:1 (assuming local disc galaxy gas-fractions). Asymmetry time-scales for moderate gas-fraction major disc mergers are ~ 0.2-0.4 Gyr, and less than 0.06 Gyr for moderate gas-fraction minor mergers. The relative orientations and orbits have little effect on the time-scales for morphological disturbances. Observational studies of close pairs often select major mergers by choosing paired galaxies with similar luminosities and/or stellar masses. Therefore, the various ways of finding galaxy mergers (G-M20, A, close pairs) are sensitive to galaxy mergers of different mass ratios. By comparing the frequency of mergers selected by different techniques, one may place empirical constraints on the major and minor galaxy merger rates.

The Complexity of Algebraic Algorithms for LWE

description: Arora & Ge introduced a noise-free polynomial system to compute the secret of a Learning With Errors (LWE) instance via linearization. Albrecht et al. later utilized the Arora-Ge polynomial model to study the complexity of Gröbner basis computations on LWE polynomial systems under the assumption of semi-regularity. In this paper we revisit the Arora-Ge polynomial and prove that it satisfies a genericity condition recently introduced by Caminata & Gorla, called being in generic coordinates. For polynomial systems in generic coordinates one can always estimate the complexity of DRL Gröbner basis computations in terms of the Castelnuovo-Mumford regularity and henceforth also via the Macaulay bound.
 Moreover, we generalize the Gröbner basis algorithm of Semaev & Tenti to arbitrary polynomial systems with a finite degree of regularity. In particular, existence of this algorithm yields another approach to estimate the complexity of DRL Gröbner basis computations in terms of the degree of regularity. In practice, the degree of regularity of LWE polynomial systems is not known, though one can always estimate the lowest achievable degree of regularity. Consequently, from a designer's worst case perspective this approach yields sub-exponential complexity estimates for general, binary secret and binary error LWE.
 In recent works by Dachman-Soled et al. the hardness of LWE in the presence of side information was analyzed. Utilizing their framework we discuss how hints can be incorporated into LWE polynomial systems and how they affect the complexity of Gröbner basis computations.

description: : This paper examines the relationship between human capital effectiveness in creating diversification for economic development in Nigeria. To enhance economic development in Nigeria adequate time and resources must be commission into developing human capital. That is providing education and training, infrastructural facilities and friendly working environment that will enable these human element to strive in different dimensions in the economy. This paper further explains that, by so doing, the knowledge, skills and competences acquired by the human element remains an assets to creating enormous ideas that will help in diversifying the economy of Nigeria from oil to non-oil sectors for future economic growth.

Minimal Z' models: present bounds and early LHC reach

description: We consider `minimal' Z' models, whose phenomenology is controlled by only three parameters beyond the Standard Model ones: the Z' mass and two effective coupling constants. They encompass many popular models motivated by grand unification, as well as many arising in other theoretical contexts. This parameterization takes also into account both mass and kinetic mixing effects, which we show to be sizable in some cases. After discussing the interplay between the bounds from electroweak precision tests and recent direct searches at the Tevatron, we extend our analysis to estimate the early LHC discovery potential. We consider a center-of-mass energy from 7 towards 10 TeV and an integrated luminosity from 50 to several hundred pb^-1, taking all existing bounds into account. We find that the LHC will start exploring virgin land in parameter space for M_Z' around 700 GeV, with lower masses still excluded by the Tevatron and higher masses still excluded by electroweak precision tests. Increasing the energy up to 10 TeV, the LHC will start probing a wider range of Z' masses and couplings, although several hundred pb^-1 will be needed to explore the regions of couplings favored by grand unification and to overcome the Tevatron bounds in the mass region around 250 GeV.

Linear theory and velocity correlations of clusters
Creators: name: Sheth, Ravi K.

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Linear theory provides a reasonable description of the velocity correlations of biased tracers both perpendicular and parallel to the line of separation, provided one accounts for the fact that the measurement is almost always made using pair-weighted statistics. This introduces an additional term which, for sufficiently biased tracers, may be large. Previous work suggesting that linear theory was grossly in error for the components parallel to the line of separation ignored this term.
