description: Multi-wavelength observations of prominence eruptions provide an opportunity to uncover the physical mechanism of the triggering and the evolution process of the eruption. In this paper, we investigated an erupting prominence on October 14, 2012, recorded in Hα, EUV, and X-ray wavelengths. The process of the eruption gives evidences on the existence of a helical magnetic structure and showing the twist being converting to writhe. The estimated twist is ~6π (3 turns), exceeding the threshold of the kink instability. The rising plasma then reached a high speed, estimated at 228 km s-1, followed by a sudden rapid acceleration at 2715 m s-2, and synchronous with a solar are. Co-spatial cusp shaped structures were observed in both AIA 131Å and 94Å images, signifying the location of the magnetic reconnection. The erupted flux rope finally undergone a deceleration with a maximum value of 391 m s-2, which is even larger than the free-fall acceleration on the Sun (273 m s-2) , suggesting that the eruption finally failed, possibly due to an inward magnetic tension force.

description: Marine oil spills at sea may cause disastrous consequences for the marine environment, especially the marine ecosystem. Satellite-based synthetic aperture radar (SAR) provides an important means for monitoring marine oil spills due to its advantages of all-weather and all-time observation ability. Thus, to make a timely damage assessment and spread control of oil spills, it is vital to accurately segment oil spills through SAR images. In oil spill SAR image segmentation, several inevitable challenges exist, and these challenges mainly include: 1) oil spills in SAR images normally exhibit various areas with irregular shapes, and this makes difficulty for accurately segmenting oil spill areas in SAR images. 2) look-alikes can be confused with oil spills and thus being a significant obstacle for segmenting real oil spill areas in SAR images. 3) the availability of oil spill SAR image data is limited in practice, and this makes difficulty in training a qualified segmentation model. To address these challenges, in this thesis, I firstly propose a novel marine oil spill SAR image segmentation method by considering the physics of SAR imagery and oil spill segmentation simultaneously to perform accurate oil spill segmentation. Secondly, I incorporate the intrinsic distribution of backscatter values in SAR images to construct a deep neural segmentation network, which is acpable of segmentation oil spill SAR images include look-alikes.
Finally, I construct a novel oil spill SAR image segmentation network by leveraging the seminal representation of SAR images and the training for oil spill segmentation comprehensively, which operates oil spill segmentation with a small amount of training data. Experimental evaluations over different types of oil spill SAR images demonstrate the proposed methods achieve an average of around 10% improvement for oil spill SAR image segmentation.

description: We investigate the transfer of coherence from atoms to a cavity field initially in a statistical mixture in a two-photon micromaser arrangement. The field is progressively modified from a maximum entropy state (thermal state) towards an almost pure state (entropy close to zero) due to its interaction with atoms sent across the cavity. We trace over the atomic variables, i.e., the atomic states are not collapsed by a detector after they leave the cavity. We find that by applying an external classical driving field it is possible to substantially increase the field purity without the need of previously preparing the atoms in a superposition of their energy eigenstates. We also discuss some of the nonclassical features of the resulting field.

description: This paper uses the Indian tariff reforms of the early nineties to estimate how households responded to the negative income shocks caused by the tariff decreases. Households more hurt by the tariff reform decreased overall expenditure, but the response is not uniform across food items. In particular, households more hurt by the reform did not change their consumption of cereals, but decreased their consumption of all other food items. Although this coping mechanism helped maintain overall levels of calorie consumption, diet diversity and the associated benefits were sacrificed.

Resonant scattering from three-dimensional optical microcavities formed in two-dimensional waveguide-based photonic crystals

Publisher: name: University of British Columbia
Year: 2009

description: Reflectivity properties of indium phosphide-(InP-)based two dimensional (2D) photonic crystals and photonic crystal microcavities were studied via optical experimentation and numerical simulations. Planar InP waveguides textured with a hexagonal array of air holes were studied with a specular white-light reflectivity apparatus. Their reflectivity as a function of wavenumber. as measured at different incident angles with an FTIR spectrometer, was compared to the results of computer simulations of the structure, based on a Green's function model. The simulation fits were used to determine salient fabrication parameters of the waveguide structures, including the filling fraction of the texturing, as well as the configuration of the layered structure of the waveguide and its substrate. The reflectivity properties of InP-based photonic crystal defect structures, which, in principle, serve as high-finesse (high Q-value) resonant microcavities. were also probed using both localized (2-μm spot size) 100-fs pulses from an optical parametric oscillator (tunable from 1.44 μm to 1.58 μm) and a broadband white light source. These reflectivity spectra revealed no evidence of modes in the microcavities. Numerical simulations were performed to study the extent to which the Q values and the field distributions of the defect states are affected by known fabrication imperfections; such as random variations in radii of the air holes in the microcavity arrays, as well as the slanting of hole sidewalks. The simulations were also used to mimic the microreflectivity experiment in order to determine the effect of the relative position of an incident Gaussian beam on the reflectivity properties of ideal photonic crystal defect cavities. The implications and insights arising from this work point to numerous recommendations for future work. These include a sample design comprising both a uniform photonic crystal region as well as a region of several photonic crystal defect microcavities; allowing for better characterization of fabrication parameters; modifications to the microreflectivity apparatus and experimental design that would likely yield better resolution of experimentally measured spectral features from resonant modes; and the controlled exploitation of symmetry-breaking to reduce modal volume for potential applications in cavity quantum electrodynamics.

description: In the context of various application scenarios and/or for the sake of strengthening field-programmable gate array (FPGA) security, the system functions of an FPGA design need to be analyzed, which can be achieved by systematically partitioning the FPGA's bitstream into manageable functional blocks and detecting their functionalities thereafter. In this paper, we propose a novel deep learning-based FPGA function block detection method with three major steps. In specific, we first analyze the format of the bitstream to obtain the mapping relationship between the configuration bits and configurable logic blocks because of the discontinuity of the configuration bits in the bitstream for one element. In order to reap the maturity of object detection techniques based on deep learning, our next step is to convert an FPGA bitstream to an image, following the proposed transformation method that takes account of both the adjacency nature of the programmable logic and the high degree of redundancy of configuration information. Once the image is obtained, a deep learning-based object detection algorithm is applied to this transformed image, and the objects detected can be reflected back to determine the function blocks of the original FPGA design. The deep neural network used for function block detection is trained and validated with a specially crafted bitstream/image dataset. Experiments have confirmed high detection accuracy of the proposed function detection method, showing a 98.11% of mean Average Precision (IoU=0.5) for 10 function blocks within a YOLOv3 detector implemented on Xilinx Zynq-7000 SoCs and Zynq UltraScale+ MPSoCs.

description: This study analyzes the potential impact of climate change on China's corn, wheat, and rice, domestic agricultural markets, and the international markets out to the year 2050. The study provides a brief background and reviews research literature of climate change effects on China's crop yields. The paper presents the potential impact of climate change on China's yields and attempts to quantify the domestic and global market impacts. The analysis has four scenarios, which assumes two future levels of greenhouse gas emissions with the effects of CO2 fertilization and no CO2 fertilization. A 27-country commodity partial equilibrium simulation mathematical programming model (PEATSim) is used for this analysis. Results indicate under CO2 fertilization, which increases yields, China's grain imports may decrease leading to a decrease in international prices. Under no CO2 fertilization, yields decrease, China's grain imports may increase leading to increased international prices.

description: The gravitino problem gives a severe constraint on the thermal leptogenesis scenario. This problem leads us to consider some alternatives to it if we try to keep the gravitino mass around the weak scale $m_{3/2} \sim 100$ GeV. We consider, in this paper, the non-thermal leptogenesis scenario in the framework of a minimal supersymmetric SO(10) model. Even if we start with the same minimal SO(10) model, we have different predictions for low-energy phenomenologies dependent on the types of seesaw mechanism. This is the case for leptogenesis: it is shown that the type-I see-saw model gives a consistent scenario for the non-thermal leptogenesis but not for type-II. The predicted inflaton mass needed to produce the observed baryon asymmetry of the universe is found to be $M_I \sim 5 \times 10^{11}$ GeV for the reheating temperature $T_R = 10^6$ GeV.

description: Brain extraction or skull stripping of magnetic resonance images (MRI) is an essential step in neuroimaging studies, the accuracy of which can severely affect subsequent image processing procedures. Current automatic brain extraction methods demonstrate good results on human brains, but are often far from satisfactory on nonhuman primates, which are a necessary part of neuroscience research. To overcome the challenges of brain extraction in nonhuman primates, we propose a fully-automated brain extraction pipeline combining deep Bayesian convolutional neural network (CNN) and fully connected three-dimensional (3D) conditional random field (CRF). The deep Bayesian CNN, Bayesian SegNet, is used as the core segmentation engine. As a probabilistic network, it is not only able to perform accurate high-resolution pixel-wise brain segmentation, but also capable of measuring the model uncertainty by Monte Carlo sampling with dropout in the testing stage. Then, fully connected 3D CRF is used to refine the probability result from Bayesian SegNet in the whole 3D context of the brain volume. The proposed method was evaluated with a manually brain-extracted dataset comprising T1w images of 100 nonhuman primates. Our method outperforms six popular publicly available brain extraction packages and three well-established deep learning based methods with a mean Dice coefficient of 0.985 and a mean average symmetric surface distance of 0.220 mm. A better performance against all the compared methods was verified by statistical tests (all p-values<10-4, two-sided, Bonferroni corrected). The maximum uncertainty of the model on nonhuman primate brain extraction has a mean value of 0.116 across all the 100 subjects...

Although under uniform excitation in a single confined microstructure typically standing spin waves are expected, all imaged spin waves showed a nonstanding character both, at and off resonance, the latter being additionally detected with microantenna-based ferromagnetic resonance. The effect of the edge quality on the spin waves was observed in micromagnetic simulations.

description: When quantifying the mixing properties of a quantum dynamical system in terms of dynamical entropy, the following scheme appears natural: observe the state of the system at regular time intervals while it evolves and determine the entropy produced over time. It is clear that this entropy will not only depend on the type of dynamics, but also on the type of observations. Intuitively, one can expect that some measurements are better suited than others to reveal information about the dynamics, whereas many will generate undesirable noise. In this paper, we show for two widely used model systems that the dynamical entropy is rather robust in this respect. More precisely, general local positive operator-valued measurements may be restricted to von Neumann type measurements for the shift on a quantum spin chain and gauge-invariant ones for the shift on a Fermion chain.

description: Spectrally efficient communication is studied for short-reach fiber-optic links with chromatic dispersion (CD) and receivers that employ direction-detection and oversampling. Achievable rates and symbol error probabilities are computed by using auxiliary channels that account for memory in the sampled symbol strings. Real-alphabet bipolar and complex-alphabet symmetric modulations are shown to achieve significant energy gains over classic intensity modulation. Moreover, frequency-domain raised-cosine (FD-RC) pulses outperform time-domain RC (TD-RC) pulses in terms of spectral efficiency for two scenarios. First, if one shares the spectrum with other users then inter-channel interference significantly reduces the TD-RC rates. Second, if there is a transmit filter to avoid interference then the detection complexity of FD-RC and TD-RC pulses is similar but FD-RC achieves higher rates.

description: In this paper, we study the small-large black hole phase transition and construct the Ruppeiner geometry for the five-dimensional charged Gauss-Bonnet-AdS black hole in the grand canonical ensemble. By making use of the equal area law, we obtain the analytical coexistence curve of the small and large black holes. Then the phase diagrams are examined. We also calculate the change of the thermodynamic volume during the small-large phase transition, which indicates that there exists a sudden change among the black hole microstructures. The corresponding normalized scalar curvature of the Ruppeiner geometry is also calculated. Combing with the empirical observation of scalar curvature, we find that for low electric potential, the attractive interaction dominates among the microstructures, while a high electric potential produces repulsive interactions. In the reduced parameter space, we observe that only attractive interaction is allowed when the coexistence region is excluded. The normalized scalar curvature also admits a critical exponent 2 and a universal constant $-\frac{1}{8}$. In particular, the value of the normalized scalar curvature keeps the same along the coexistence small and large black hole curves. So in the grand canonical ensemble, the interaction can keep constant at the phase transition where the black hole microstructures change. These results disclose the intriguing microstructures for the charged AdS black hole in the Gauss-Bonnet gravity.

description: Different from shopping at retail stores, consumers on e-commerce platforms usually cannot touch or try products before purchasing, which means that they have to make decisions when they are uncertain about the outcome (e.g., satisfaction level) of purchasing a product. To study people's preferences, economics researchers have proposed the hypothesis of Expected Utility (EU) that models the subject value associated with an individual's choice as the statistical expectations of that individual's valuations of the outcomes of this choice. Despite its success in studies of game theory and decision theory, the effectiveness of EU, however, is mostly unknown in e-commerce recommendation systems. Previous research on e-commerce recommendation interprets the utility of purchase decisions either as a function of the consumed quantity of the product or as the gain of sellers/buyers in the monetary sense. As most consumers just purchase one unit of a product at a time and most alternatives have similar prices, such modeling of purchase utility is likely to be inaccurate in practice. In this paper, we interpret purchase utility as the satisfaction level a consumer gets from a product and propose a recommendation framework using EU to model consumers' behavioral patterns. We assume that consumer estimates the expected utilities of all the alternatives and choose products with maximum expected utility for each purchase. To deal with the potential psychological biases of each consumer, we introduce the usage of Probability Weight Function (PWF) and design our algorithm based on Weighted Expected Utility (WEU). Empirical study on real-world e-commerce datasets shows that our proposed ranking-based recommendation framework achieves statistically significant improvement against both classical Collaborative Filtering/Latent Factor Models and state-of-the-art deep models in top-K recommendation.

description: The logistic regression models has been widely used in the social and natural sciences and results from studies using this model can have significant impact. Thus, confidence in the reliability of inferences drawn from these models is essential. The robustness of such inferences is dependent on sample size. The purpose of this study is to examine the impact of sample size on the mean estimated bias and efficiency of parameter estimation and inference for the logistic regression model. A number of simulations are conducted examining the impact of sample size, nonlinear predictors, and multicollinearity on substantive inferences (e.g. odds ratios, marginal effects) and goodness of fit (e.g. pseudo-R2, predictability) of logistic regression models. Findings suggest that sample size can affect parameter estimates and inferences in the presence of multicollinearity and nonlinear predictor functions, but marginal effects estimates are relatively robust to sample size.

We also investigate some standard properties of the schematization functor helpful for the description of the schematization of smooth projective complex varieties. In a companion paper these results are used in the construction of a non-abelian Hodge structure on the schematic homotopy type of a smooth projective variety.

description: We investigate the stability properties of a multi-converter power system model, defined on a high-order manifold. For this, we identify its symmetry (i.e., rotational invariance) generated by a static angle shift and rotation of AC signals. We characterize the steady state set, primarily determined by the steady state angles and DC power input. Based on eigenvalue conditions of its Jacobian matrix, we show asymptotic stability of the multi-converter system in a neighborhood of the synchronous steady state set by applying the center manifold theory. We guarantee the eigenvalue conditions via an explicit approach. Finally, we demonstrate our results based on a numerical example involving a network of identical DC/AC converter systems.

Distribution
Korea? (GB) (Lee et al. 1994), Japan (Hokkaido, Honshu, Shikoku, Kyushu, Nansei Islands) (Miyamoto and Hayashi 1998, Noishiki 2020, Watanabe 2020, Ito and Nakajima 2021, Mariko et al. 2024), Russia (Far East: South Sakhalin, Primorsky Krai) (Kanyukova 1988, Kanyukova and Egorov 2022).
Notes
Mesovelia egorovi was initially recorded from South Korea by Lee et al. (1994), based on an unspecified number of specimens from Mt. Palgongsan, Gyeongsangbuk-do Province. These specimens were apparently collected from a mountainous habitat, far from the coastline (see Kanyukova and Egorov (2022) for details). However, all known records of M. egorovi are restricted to salt marshes and estuaries from the Russian Far East (Kanyukova and Egorov 2022) and Hokkaido and Honshu in Japan (Miyamoto and Hayashi 1998, Watanabe 2020). No additional specimens or distributional records of M. egorovi have been reported in South Korea since its initial report. Based on this evidence, the distributional record of M. egorovi in South Korea is regarded as doubtful; similar suggestions were made by early authors (Aukema et al. 2013, Kanyukova and Egorov 2022). Collection efforts in salt marshes and lagoons in Goseong, Sokcho and Gangneung, along the north-eastern coastline in South Korea by the authors also failed to locate this species.

description: In this paper, the financial/ownership structures of agribusiness co-operatives (co-ops) are analyzed in order to examine whether new co-op models perform better than the more traditional ones. The assessment procedure introduces a new financial decision-aid approach, which is based on data-analysis techniques in combination with a Preference Ranking Organization Method of Enrichment Evaluations (PROMETHEE II). The application of this multi-criteria decision-aid approach allows the rank ordering of the co-ops on the basis of the most prominent financial ratios. The financial ratios were selected using principal component analysis. This analytical procedure reduces the dimensionality of large numbers of interrelated financial performance measures. We assess the financial success of selected EU agribusiness co-ops for the period 1999-2007. Results show that there is no clear-cut evidence that co-op models used to attract outside equity perform better than the more traditional models. This suggests that ownership structure of co-ops is not a decisive factor for their financial success.

description: We present the first fully and uniformly sampled, spatially complete HI survey of the entire Magellanic System with high velocity resolution, performed with the Parkes Telescope. The final data-cubes have an rms noise of sigma ~ 0.05 K and an effective angular resolution of 16 arcmin. The Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC) are associated with huge gaseous features with a total HI mass of M(HI) = 4.87 10^8 M_sun [d/55 kpc]^2, if all HI gas is at the same distance of 55 kpc. Approximately two thirds of this HI gas is located close to the Magellanic Clouds (Magellanic Bridge and Interface Region), and 25% of the HI gas is associated with the Magellanic Stream. The Leading Arm has a four times lower HI mass than the Magellanic Stream, corresponding to 6% of the total HI mass of the gaseous features. We have analyzed the velocity field of the Magellanic Clouds and their neighborhood introducing a LMC-standard-of-rest frame. The HI in the Magellanic Bridge shows low velocities relative to the Magellanic Clouds suggesting an almost parallel motion, while the gas in the Interface Region has significantly higher relative velocities indicating that this gas is leaving the Magellanic Bridge building up a new section of the Magellanic Stream. The clouds in the Magellanic Stream and the Leading Arm show significant differences, both in the column density distribution and in the shapes of the line profiles. The HI gas in the Magellanic Stream is more smoothly distributed than the gas in the Leading Arm. These morphological differences can be explained if the Leading Arm is at considerably lower z-heights and embedded in a higher pressure ambient medium.

Characterization of the molecular mechanisms underlying the cadherin-mediated differentiation of human trophoblastic cells

description: The majority of the biological functions of the human placenta are performed by the syncytial trophoblast layer, a multinucleated cell that is formed by the terminal differentiation and fusion of the underlying layer of mitotically active, mononucleate cytotrophoblasts. This key step in the formation and organization of the placenta is mediated by a decrease in E-cadherin (E-cad) and a concomitant increase in the levels of Cadherin-11 (cad-11) expressed on the surface of differentiating trophoblastic cells. Similarly, aberrant expression of these two cadherin subtypes has also been associated with the development of persistent trophoblastic disease in vivo. To identify the mechanisms underlying the switch in cadherin expression in human trophoblasts, we examined the mRNA levels and the protein levels of Snail and Slug, 2 zinc finger transcription repressors that regulate E-cad expression, and Twist, a transcription factor associated with tumor metastasis, in BeWo choriocarcinoma cells undergoing differentiation and fusion in response to the intracellular secondary messenger, cAMP. Quantitative Competitive Polymerase Chain Reaction (QC-PCR) analysis revealed significant declines in E-cadherin mRNA levels in BeWo choriocarcinoma cells after 12h of culture in the presence of cAMP. The levels of this mRNA transcript continued to decline until the termination of these studies at 48h. Western blot analysis and immunostaining also demonstrated a significant decrease in the protein levels of Ecadherin in response to cAMP. A significant and continuous increase in Snail mRNA levels and protein levels were detected in these trophoblastic cells over time in culture with cAMP using QC-PCR and Western Blot. Intense immunostaining for Snail expression was also detected in the nuclei of cultured BeWo cells. However, the levels of the mRNA transcript encoding Slug remained relatively low and constant, at least at the time points examined in these studies. There was also a significant increase in Twist mRNA levels and protein levels as the BeWo cells underwent terminal differentiation and fusion. Collectively, these observations suggest that Snail and Twist regulate the switch in cadherin subtypes expressed, on the surface of human trophoblastic cells, a cellular event underlying the formation of multinucleated syncytium in vivo and in vitro. Future studies will examine the effects of loss-, or gain-of-function of Snail and Twist on the terminal differentiation and fusion of human trophoblastic cells in vitro.

description: Strong many-body interactions in two-dimensional (2D) semiconductors give rise to efficient exciton-exciton annihilation (EEA). This process is expected to result in the generation of unbound high energy carriers. Here, we report an unconventional photoresponse of van der Waals heterostructure devices resulting from efficient EEA. Our heterostructures, which consist of monolayer transition metal dichalcogenide (TMD), hexagonal boron nitride (hBN), and few-layer graphene, exhibit photocurrent when photoexcited carriers possess sufficient energy to overcome the high energy barrier of hBN. Interestingly, we find that the device exhibits moderate photocurrent quantum efficiency even when the semiconducting TMD layer is excited at its ground exciton resonance despite the high exciton binding energy and large transport barrier. Using ab initio calculations, we show that EEA yields highly energetic electrons and holes with unevenly distributed energies depending on the scattering condition. Our findings highlight the dominant role of EEA in determining the photoresponse of 2D semiconductor optoelectronic devices.
