description: Leaf yellowing caused by chlorophyll degradation directly reduces the commercial quality of post-harvest Chinese flowering cabbage. However, the mechanism of chlorophyll degradation in post-harvest Chinese flowering cabbage remains unclear. In this work, we identified a leaf senescence-responsive NAC family transcription factor, a homologue of JUB1 in Arabidopsis, termed BrJUB1 in post-harvest Chinese flowering cabbage. The expression of BrJUB1 was found to increase continuously during storage time, accompanied by an upregulation of chlorophyll catabolic genes (CCGs) and reduced chlorophyll content. Subcellular localisation and transactivation analyses in tobacco revealed that BrJUB1 possessed two characteristics of transcription factors: nuclear localisation and transactivation of gene activity. More importantly, electrophoretic mobility shift assay and dual-luciferase analysis demonstrated that BrJUB1 bound to NAC recognition sequence in the promoters of major CCGs including BrNYC1, BrPAO, BrPPH1 and BrSGR1, and activated their transcription. Taken together, these findings show that BrJUB1 might act as an important regulator in leaf senescence of post-harvest Chinese flowering cabbage through activating chlorophyll degradation. This study expands our understanding of molecular mechanisms involved in leaf senescence of harvested Chinese cabbage and possibly other leafy vegetables.

description: The Klein-Gordon and the Dirac equations with vector and scalar potentials are investigated under a more general condition, $V_{v}+V_{s}= \mathrm{constant}$. These intrinsically relativistic and isospectral problems are solved in a case of squared hyperbolic potential functions and bound states for either particles or antiparticles are found. The eigenvalues and eigenfuntions are discussed in some detail and the effective Compton wavelength is revealed to be an important physical quantity. It is revealed that a boson is better localized than a fermion when they have the same mass and are subjected to the same potentials.

description: Relativistic AGN jets exhibit multi-timescale variability and a broadband non-thermal spectrum extending from radio to gamma-rays. These highly magnetized jets are prone to undergo several Magneto-hydrodynamic (MHD) instabilities during their propagation in space and could trigger jet radiation and particle acceleration. This work aims to study the implications of relativistic kink mode instability on the observed long-term variability in the context of the twisting in-homogeneous jet model. To achieve this, we investigate the physical configurations preferable for forming kink mode instability by performing high-resolution 3D relativistic MHD simulations of a portion of highly magnetized jets. In particular, we perform simulations of cylindrical plasma column with Lorentz factor $\geq 5$ and study the effects of magnetization values and axial wave-numbers with decreasing pitch on the onset and growth of kink instability. We have confirmed the impact of axial wave-number on the dynamics of the plasma column including the growth of the instability. In this work, we have further investigated the connection between the dynamics of the plasma column with its time-varying emission features. From our analysis, we find a correlated trend between the growth rate of kink mode instability and the flux variability obtained from the simulated light curve.

description: Improvements in tracking technology through optical and computer vision systems have enabled a greater understanding of the movement-based behaviour of multiple agents, including in team sports. In this study, a Multi-Agent Statistically Discriminative Sub-Trajectory Mining (MA-Stat-DSM) method is proposed that takes a set of binary-labelled agent trajectory matrices as input and incorporates Hausdorff distance to identify sub-matrices that statistically significantly discriminate between the two groups of labelled trajectory matrices. Utilizing 2015/16 SportVU NBA tracking data, agent trajectory matrices representing attacks consisting of the trajectories of five agents (the ball, shooter, last passer, shooter defender, and last passer defender), were truncated to correspond to the time interval following the receipt of the ball by the last passer, and labelled as effective or ineffective based on a definition of attack effectiveness that we devise in the current study. After identifying appropriate parameters for MA-Stat-DSM by iteratively applying it to all matches involving the two top- and two bottom-placed teams from the 2015/16 NBA season, the method was then applied to selected matches and could identify and visualize the portions of plays, e.g., involving passing, on-, and/or off-the-ball movements, which were most relevant in rendering attacks effective or ineffective.

description: We study one dimensional Bose liquids of interacting ultracold atoms in the Y-shaped potential when each branch is filled with atoms. We find that the excitation packet incident on a single Y-junction should experience a negative density reflection analogous to the Andreev reflection at normal-superconductor interfaces, although the present system does not contain fermions. In a ring interferometer type configuration, we find that the transport is completely insensitive to the (effective) flux contained in the ring, in contrast to the Aharonov-Bohm effect of a single particle in the same geometry.

Ignoring the optimal set of tissue-specific metabolic networks can bias the intepretation of data

description: Tissue specific constraint-based modeling approachess have proven useful as automatic ways of extracting and analyzing metabolic networks that capture the different metabolic states of cells. These methods integrate different sources of information such as stoichiometry, transcriptomics or metabolomics data that constrain the space of possible metabolic networks. This process is usually done by searching for a metabolic network that minimizes an objective function measuring the discrepancy between the observed data and the model. However, current methods usually extract one single optimal network from which all the subsequent analysis is derived. However, this solution may be not unique, meaning that the observed data can be explained by a set of equally good metabolic networks. Ignoring this variability may lead to incorrect or incomplete explanations and bias the interpretation. In order to analyze this effect, we developed an extension of iMAT, a method for extracting tissue-specific networks from transcriptomics data, to enumerate different alternative optimal networks generated from the same data. Our study highlights the importance of analyzing the space of alternative optimal solutions as a way to reduce potential bias in the interpretation of data using constraint-based modeling approaches.
Evaluation of long-term effects of early auditory deprivation: an animal model for otitis media
Creators: name: Adam, Trudy
Publisher: name: University of British Columbia
Year: 2008

description: This project aimed to establish a developmental animal model for the long-term effects of Otitis Media experienced in youth. The procedure employed was based on a model that mimmics the acute physiological symptomology of the syndrome. It consisted of the infusion of lipopolysaccharides (derived from the plasmolemmae of Klebsiella pneumoniae, a pathogen known to cause the infection in nature) into the middle ear cavity. In the young (12 day old) animal, it was found that a dosage 200 times that employed in previous models was necessary to induce like symptomology. This is thought to be due to the boosted immunity of the present rat pups stemming from clostrum in the mother’s initial milk production. Rat pups were raised to an age of approximately 35 days with their respective effusion conditions. Groups of rats were used to study the effects of monolateral versus bilateral infections, severe versus mild hearing reductions, and in steady-state versus fluctuating conditions. During and after the experience of middle ear effusion produced by lipopolysaccharide injection, audiograms were constructed to examine reductions in hearing level associated with the presence of the mucoid mass. Upon adulthood, prior to any other testing, open-field behavior was examined; focussing on exploration and re-exploration tendancies, reaction to novelty, and habituation to new environments. No consistent differences were noted for emotionality, reaction to novelty, or exploratory behavior in general. Subsequently, the spatial navigational abilities of rats being studied were examined. Testing was conducted in both the visual (non-deprived) and auditory (deprived) modalities, employing the standard spatial water maze task. As expected, no group differences were observed in the visual version of the task. However, the auditory task also failed to detect group differences. Implications and directions for future study of Otitis Media are discussed, and alternative behavioral paradigms suggested.

description: We present a strong lensing analysis of the galaxy cluster PSZ1 G311.65-18.48 (z=0.443) using multi-band observations with Hubble Space Telescope, complemented with VLT/MUSE spectroscopic data. The MUSE observations provide redshift estimates for the lensed sources and help reducing the mis-identification of the multiple images. Spectroscopic data are also used to measure the inner velocity dispersions of 15 cluster galaxies and calibrate the scaling relations to model the subhalo cluster component. The model is based on 62 multiple images grouped in 17 families belonging to 4 different sources. The majority of them are multiple images of compact stellar knots belonging to a single star-forming galaxy at z=2.3702. This source is strongly lensed by the cluster to form the Sunburst Arc system. To accurately reproduce all the multiple images, we build a parametric mass model, which includes both cluster-scale and galaxy-scale components. The resulting model has a r.m.s. separation between the model-predicted and the observed positions of the multiple images of only 0.14''. We conclude that PSZ1 G311.65-18.48 has a relatively round projected shape and a large Einstein radius (29'' for z_s = 2.3702), which could indicate that the cluster is elongated along the line of sight. The Sunburst Arc source is located at the intersection of a complex network of caustics, which explains why parts of the arc are imaged with unprecedented multiplicity (up to 12 times).
Steady-state evolution of debris disks around A stars

description: In this paper a simple analytical model for the steady-state evolution of debris disks due to collisions is confronted with Spitzer observations of main sequence A stars. All stars are assumed to have planetesimal belts with a distribution of initial masses and radii. In the model disk mass is constant until the largest planetesimals reach collisional equilibrium whereupon the mass falls off oc 1/t. We find that the detection statistics and trends seen at both 24 and 70um can be fitted well by the model. While there is no need to invoke stochastic evolution or delayed stirring to explain the statistics, a moderate rate of stochastic events is not ruled out. Potentially anomalous systems are identified by a high dust luminosity compared with the maximum permissible in the model (HD3003, HD38678, HD115892, HD172555). Their planetesimals may have unusual properties (high strength or low eccentricity) or this dust could be transient. While transient phenomena are also favored for a few systems in the literature, the overall success of our model, which assumes planetesimals in all belts have the same strength, eccentricity and maximum size, suggests a large degree of uniformity in the outcome of planet formation. The distribution of planetesimal belt radii, once corrected for detection bias, follows N(r) oc r^{-0.8+-0.3} for 3-120AU. Since the inner edge is often attributed to an unseen planet, this provides a unique constraint on the planetary systems of A stars. It is also shown that P-R drag may sculpt the inner edges of A star disks close to the Spitzer detection threshold (HD2262, HD19356, HD106591, HD115892). This model can be readily applied to the interpretation of future surveys, and predictions are made for the upcoming SCUBA-2 survey, including that >17% of A stars should be detectable at 850um.

description: We study the entanglement entropy of free fermions in 2d in the presence of a partially transmitting interface that splits Minkowski space into two half-spaces. We focus on the case of a single interval that straddles the defect, and compute its entanglement entropy in three limits: Perturbing away from the fully transmitting and fully reflecting cases, and perturbing in the amount of asymmetry of the interval about the defect. Using these results within the setup of the Poincaré patch of AdS$_2$ statically coupled to a zero temperature flat space bath, we calculate the effect of a partially transmitting AdS$_2$ boundary on the location of the entanglement island region. The partially transmitting boundary is a toy model for black hole graybody factors. Our results indicate that the entanglement island region behaves in a monotonic fashion as a function of the transmission/reflection coefficient at the interface.

description: Hadamard spectroscopy has earlier been used to speed-up multi-dimensional NMR experiments. In this work we speed-up the two-dimensional quantum computing scheme, by using Hadamard spectroscopy in the indirect dimension, resulting in a scheme which is faster and requires the Fourier transformation only in the direct dimension. Two and three qubit quantum gates are implemented with an extra observer qubit. We also use one-dimensional Hadamard spectroscopy for binary information storage by spatial encoding and implementation of a parallel search algorithm.

Investigation of selected variables from the primary and secondary circulatory systems in rainbow trout (Oncorhynchus mykiss)
Creators: name: Ahlborn, Dorit
Publisher: name: University of British Columbia
Year: 2008

description: A series of experiments are reported which utilize a cannulating method for the secondary circulation. A modification of a new method for cannulating the secondary system in rainbow trout (Oncorhynchus mykiss) is described. A T-shaped catheter was placed inside the lateral cutaneous vessel, thereby allowing multiple samples to be taken from the same animal. Rainbow trout were cannulated in both the primary and secondary circulatory systems. Repeated samples were taken over several days to determine the concentrations of selected parameters. White blood cell numbers were significantly greater in the secondary system; however, they also varied much more than the cell numbers in the primary circulation suggesting that blood cell composition changes within the secondary circulation. Concentrations of selected parameters from the secondary circulation were calculated as a percentage of the primary system: plasma cortisol was 60.2 ± 9.7%; total protein was 72.9 ± 4.9%,plasma glucose was 90.3 ± 11.4%, plasma chloride was 97.8 ± 1.9%, and hematocrit was 0.5 ± 0.2%. Only glucose and chloride concentrations did not differ significantly between the two systems. Adrenaline was determined to be 64.9 ± 17.3% in the secondary compared to the primary circulation; however, since this hormone was detectable in only a few samples, this value may not be representative of the system. A sharp increase in the cortisol concentration of the primary system 48 hours after operation was observed again approximately two hours later in the secondary system, suggesting a slow mixing time between the primary and secondary circulation. Fish were vaccinated with an intraperitoneal injection of Vibrio anguillarum to investigate the possible role of the secondary system in immune function. As in the first experiment, the white blood cell numbers were significantly greater and more variable in the secondary compared to the primary circulation. The concentrations of selected plasma constituents in the secondary system were also determined as percentages of the primary circulation: lysozyme was 114.9± 14.9%, cortisol was 51.4 ± 17.2%, total protein was 71.1 ±7.5%, glucose was 92.1 ± 11.8%, and chloride was 96.4 ±2.3%. Only total protein was significantly different between the two circulatory systems. A low response in the hemolytic plaque assay and a negative outcome from antibody titer tests in both circulatory systems, suggests that the adaptive (specific) immune response may not have been stimulated.

description: Deep learning enhances earthquake monitoring capabilities by mining seismic waveforms directly. However, current neural networks, trained within specific areas, face challenges in generalizing to diverse regions. Here, we employ a data recombination method to create generalized earthquakes occurring at any location with arbitrary station distributions for neural network training. The trained models can then be applied to various regions with different monitoring setups for earthquake detection and parameter evaluation from continuous seismic waveform streams. This allows real-time Earthquake Early Warning (EEW) to be initiated at the very early stages of an occurring earthquake. When applied to substantial earthquake sequences across Japan and California (US), our models reliably report earthquake locations and magnitudes within 4 seconds after the first triggered station, with mean errors of 2.6-6.3 km and 0.05-0.17, respectively. These generalized neural networks facilitate global applications of real-time EEW, eliminating complex empirical configurations typically required by traditional methods.

description: To determine the origin of the spiral structure observed in the dust continuum emission of Elias 2-27 we analyze multi-wavelength continuum ALMA data with a resolution of $\sim$0.2 arcsec ($\sim$23au) at 0.89, 1.3 and 3.3mm. We also study the kinematics of the disk with $^{13}$CO and C$^{18}$O ALMA observations in the $J=$3-2 transition. The spiral arm morphology is recovered at all wavelengths in the dust continuum observations, where we measure contrast and spectral index variations along the spiral arms and detect subtle dust-trapping signatures. We determine that the emission from the midplane is cold and interpret the optical depth results as signatures of a higher disk mass than previous constraints. From the gas data, we search for deviations from Keplerian motion and trace the morphology of the emitting surfaces and the velocity profiles. We find an azimuthally varying emission layer height in the system, large-scale emission surrounding the disk, and strong perturbations in the channel maps, co-located with the spirals. Additionally, we develop multigrain dust and gas SPH simulations of a gravitationally unstable disk and compare them to the observations. Given the large scale emission and highly perturbed gas structure, together with the comparison of continuum observations to theoretical predictions, we propose infall-triggered gravitational instabilities as origin for the observed spiral structure.

Strategies and the Language Learner
Creators: name: D’Este, Claudia
Publisher: name: Università Ca’ Foscari Venezia, Italia
Year: 2012

description:

The active role of the learner in the language learning process has been thoroughly acknowledged in the past fifty years. The discussion on the centrality of the learner in the acquisi- tion of a second (L2) or foreign language (FL) is essentially based on the postulate that the charac- teristics of the learner affect the way in which the second or foreign language is acquired and that successful learners appear to have common personal features. Research on the language learner has demonstrated that every person learning a language has his or her own peculiar features and considerable personal baggage which must be taken into account throughout the learning pro- cess. Individual differences in foreign and second language learning can be identified in character- istics such as age, gender and aptitude, and in factors such as motivation, styles and strategies. This paper will first focus on the development of research on the language learner and on the main issues concerning language learner’s aptitude, motivation, and, in particular, on learner strategies. Age, styles and gender will not be considered as research on these characteristics also involves a deep analysis of sociological and psychological issues which are beyond the aim of this paper. The second part will concentrate on language learner strategies involved in language testing situations and on how the use of these strategies affects the test, its quality and, namely, its validity.

description: Diffusion models have shown their effectiveness in generation tasks by well-approximating the underlying probability distribution. However, diffusion models are known to suffer from an amplified inherent bias from the training data in terms of fairness. While the sampling process of diffusion models can be controlled by conditional guidance, previous works have attempted to find empirical guidance to achieve quantitative fairness. To address this limitation, we propose a fairness-aware sampling method called \textit{attribute switching} mechanism for diffusion models. Without additional training, the proposed sampling can obfuscate sensitive attributes in generated data without relying on classifiers. We mathematically prove and experimentally demonstrate the effectiveness of the proposed method on two key aspects: (i) the generation of fair data and (ii) the preservation of the utility of the generated data.

description: We consider the dynamics of a non-recombining haploid population of finite size which accumulates deleterious mutations irreversibly. This ratchet like process occurs at a finite speed in the absence of epistasis, but it has been suggested that synergistic epistasis can halt the ratchet. Using a diffusion theory, we find explicit analytical expressions for the typical time between successive clicks of the ratchet for both non-epistatic and epistatic fitness functions. Our calculations show that the inter-click time is of a scaling form which in the absence of epistasis gives a speed that is determined by size of the least-loaded class and the selection coefficient. With synergistic interactions, the ratchet speed is found to approach zero rapidly for arbitrary epistasis. Our analytical results are in good agreement with the numerical simulations.

description:

The essay presents the results of a project on the use of multiple intelligence tests in grades 6-8. The aim was to gather data on the learning styles of migrant students in multilevel classes. The test was administered to migrant students in phase1, and to the whole class in phase 2. The results of phase 1 show the migrant students’ problems with CALP in Italian as a Second Language, while the results of phase 2 show the difference between mother tongue and migrant students. In the light of these data, individualized activities have been proposed which take into consideration the types of intelligence prevailing in each student or in groups of students.

MDMA-assisted psychotherapy rapidly decreases PTSD symptoms, dissociation, depression, and functional disability : a systematic review and meta-analysis
Creators: name: Green, WM
Publisher: name: University of Tasmania
Year: 2024

description: Current treatment of posttraumatic stress disorder (PTSD) targets 5-HT receptors with selective serotonin reuptake inhibitors (SSRIs) in combination with psychotherapy. It is ineffective in many cases. Four decades have passed without any clinically meaningful alternative. Here we show MDMA (3, 4-methylenedioxymethamphetamine)-assisted therapies are effective in reducing PTSD symptoms, dissociation severity, comorbid depression, and functional disability. A systematic literature search identified randomised control trials (RCTs) in adult participants with treatment-resistant PTSD. The result was streamlined using Covidence systematic review software. A random-effects meta-analysis was performed for each dependent variable using Review Manager (RevMan). The protocol followed the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. A total of six RCTs, constituting 169 participants, were included. MDMA-assisted psychotherapy decreases PTSD symptoms, MD = -19.37, 95% CI [-29.02, -9.73], p<.001; dissociation severity, MD = -9.75, 95% CI [ -13.39, -6.12], p<.001; comorbid depression, MD = -11.13, 95% CI [-19.35, -2.92], p = 0.008; sleep disturbance MD = -3.67, 95% CI [ -7.70, 0.36], p = 0.07; and increases daily functioning, SMD = 0.92, 95% CI [0.10, 1.73], p = 0.03. These data suggest MDMA-assisted therapies is effective for PTSD and indicates there is potential for clinical translation.
An introductory review on resource theories of generalized nonclassical light

description: Quantum resource theory is perhaps the most revolutionary framework that quantum physics has ever experienced. It plays vigorous roles in unifying the quantification methods of a requisite quantum effect as wells as in identifying protocols that optimize its usefulness in a given application in areas ranging from quantum information to computation. Moreover, the resource theories have transmuted radical quantum phenomena like coherence, nonclassicality and entanglement from being just intriguing to being helpful in executing realistic thoughts. A general quantum resource theoretical framework relies on the method of categorization of all possible quantum states into two sets, namely, the free set and the resource set. Associated with the set of free states there is a number of free quantum operations emerging from the natural constraints attributed to the corresponding physical system. Then, the task of quantum resource theory is to discover possible aspects arising from the restricted set of operations as resources. Along with the rapid growth of various resource theories corresponding to standard harmonic oscillator quantum optical states, significant advancement has been expedited along the same direction for generalized quantum optical states. Generalized quantum optical framework strives to bring in several prosperous contemporary ideas including nonlinearity, $\mathcal{PT}$-symmetric non-Hermitian theories, $q$-deformed bosonic systems, etc., to accomplish similar but elevated objectives of the standard quantum optics and information theories. In this article, we review the developments of nonclassical resource theories of different generalized quantum optical states and their usefulness in the context of quantum information theories.

Nonlocal spin Hall effect and spin-orbit interaction in nonmagnetic metals

description: Spin Hall effect in a nonlocal spin-injection device is theoretically studied. Using a nonlocal spin-injection technique, a pure spin current is created in a nonmagnetic metal (N). The spin current flowing in N is deflected by spin-orbit scattering to induce the Hall current in the transverse direction and accumulate charge at the edges of N, yielding the spin-current induced Hall effect. We propose a method for extracting information for spin-orbit scattering in nonmagnetic metals.

Optical conductivity of polaronic charge carriers

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: The optical conductivity of charge carriers coupled to quantum phonons is studied in the framework of the one-dimensional spinless Holstein model. For one electron, variational diagonalisation yields exact results in the thermodynamic limit, whereas at finite carrier density analytical approximations based on previous work on single-particle spectral functions are obtained. Particular emphasis is put on deviations from weak-coupling, small-polaron or one-electron theories occurring at intermediate coupling and/or finite carrier density. The analytical results are in surprisingly good agreement with exact data, and exhibit the characteristic polaronic excitations observed in experiments on manganites.

Planetary magnetosphere evolution around post-main-sequence stars

description: Accompanying the mounting detections of planets orbiting white dwarfs and giant stars are questions about their physical history and evolution, particularly regarding detectability of their atmospheres and potential for habitability. Here we determine how the size of planetary magnetospheres evolve over time from the end of the main sequence through to the white dwarf phase due to the violent winds of red giant and asymptotic giant branch stars. By using a semianalytic prescription, we investigate the entire relevant phase space of planet type, planet orbit and stellar host mass (1-7Msun). We find that a planetary magnetosphere will always be quashed at some point during the giant branch phases unless the planet's magnetic field strength is at least two orders of magnitude higher than Jupiter's current value. We also show that the time variation of the stellar wind and density generates a net increase in wind ram pressure and does not allow a magnetosphere to be maintained at any time for field strengths less than 10^{-5} T (0.1 G). This lack of protection hints that currently potentially habitable planets orbiting white dwarfs would have been previously inhospitable.

description: We investigate a new approach to the detection of companions to extrasolar planets beyond the transit method. We discuss the possibility of the existence of binary planets. We develop a method based on the imaging of a planet-companion as an unresolved system (but resolved from its parent star). It makes use of planet-companion mutual phenomena, namely mutual transits and mutual shadows. We show that companions can be detected and their radius measured down to lunar sizes.

description: This research addresses the complex challenge of automated repair of code vulnerabilities, vital for enhancing digital security in an increasingly technology-driven world. The study introduces a novel and efficient format for the representation of code modification, using advanced Large Language Models (LLMs) such as Code Llama and Mistral. These models, fine-tuned on datasets featuring C code vulnerabilities, significantly improve the accuracy and adaptability of automated code repair techniques. A key finding is the enhanced repair accuracy of these models when compared to previous methods such as VulRepair, which underscores their practical utility and efficiency. The research also offers a critical assessment of current evaluation metrics, such as perfect predictions, and their limitations in reflecting the true capabilities of automated repair models in real-world scenarios. Following this, it underscores the importance of using test datasets devoid of train samples, emphasizing the need for dataset integrity to enhance the effectiveness of LLMs in code repair tasks. The significance of this work is its contribution to digital security, setting new standards for automated code vulnerability repair and paving the way for future advancements in the fields of cybersecurity and artificial intelligence. The study does not only highlight the potential of LLMs in enhancing code security but also fosters further exploration and research in these crucial areas.
