description: The notion of low-noise channels was recently proposed and analyzed in detail in order to describe noise-processes driven by environment [M. Hotta, T. Karasawa and M. Ozawa, Phys. Rev. A72, 052334 (2005)]. An estimation theory of low-noise parameters of channels has also been developed. In this report, we address the low-noise parameter estimation problem for the $N$-body extension of low-noise channels. We perturbatively calculate the Fisher information of the output states in order to evaluate the lower-bound of the mean-square error of the parameter estimation. We show that the maximum of the Fisher information over all input states can be attained by a factorized input state in the leading order of the low-noise parameter. Thus, to achieve optimal estimation, it is not necessary for there to be entanglement of the $N$ subsystems, as long as the true low-noise parameter is sufficiently small.

Testing habitat suitability models for Roosevelt elk

Publisher: name: University of British Columbia

description: Seasonal habitat suitability models for Roosevelt elk, Cervus elaphus roosevelti, (Brunt 1991) were tested using two distinctly different study areas on northern Vancouver Island, British Columbia. Locations for 5 radio-collared elk, obtained approximately twice per week by telemetry from May 1992 to August 1993, were used to test the models. I used the adaptive kernel method to estimate seasonal home ranges from each elk's locations. Habitat suitability values for summer, mild winter, and severe winter were calculated across each study area on a geographic information system (GIS), using input variables from forest cover, topology, and understory coverages. I compared the suitability values of elk locations to values within home ranges and across study areas, and the suitability values of seasonal home ranges to those across the study areas. The home ranges were further compared with equal sized, circular areas randomly placed in the study areas. Because elk generally used areas of higher suitability than expected, I concluded that the model had some ability to predict areas which contained suitable elk habitat. I also identified limitations of the model.

description: Summarizing the economic Eustathio’s ideas who studied, we find that Eustathios praises work. Regarding professions, yields in agriculture primacy between human occupations and reject trade and crafts. Probably defends the ideal of self-sufficiency and appears skeptical of the market and its laws. Eustathios condemns usury and all tactics that work against the poor and the weak and resents the taxes and particularly the presser tax collectors. He contemns slavery and inhuman attitude towards slaves. Accepts fairly accumulated wealth which can be redistributed to the poor through charity and alms. Moreover celebrates the catalytic role of the poor in a Christian society, who have secured a place in Paradise. He hates the change of social stratification, if it considers that the social status everyone had resulted sulfur and infallible design

description: Reconstruction of digital breast tomosynthesis is a challenging problem due to the limited angle data available in such systems. Due to memory limitations, deep learning-based methods can help improve these reconstructions, but can not (yet) attain sufficiently high resolution. In addition to this practical issue, questions remain on the possibility of such models introducing 'ghost' information from the training data that is not compatible with the projection data. To take advantage of some of the benefits of deep learning-based reconstructions while avoiding these limitations, we propose to use the low resolution deep learning-based reconstruction as an initialization of a regular high resolution iterative method. The network was trained using digital phantoms, some based on a mathematical model and some derived from patient dedicated breast CT scans. The output of this network was then used as initialization for 10 000 iterations of MLTR for nine patient based phantoms that were not included in the training. The same nine cases were also reconstructed without any initialization for comparison. The reconstructions including initialization were found to reach a lower mean squared error than those without, and visual inspection found much improved retrieval of the breast outline and depiction of the skin, confirming that adding the deep learning-based initialization adds valuable information to the reconstruction.

description: We present the highest resolution VLBI imaging observations of Sgr A* made at both 7 and 3.5 mm. These data reveal wavelength-dependent intrinsic sizes with an intrinsic emitting region at 3.5 mm of about 1 AU (at a distance of 8 kpc to the Galactic Center). When combined with the lower limit on the mass of Sgr A*, these size measurements provide strong evidence that Sgr A* is a super-massive black hole. We also detected a structural variation which results in an intrinsically symmetrical structure that increases in its intrinsic size by more than 25% at 7 mm.

description: The first excitation energy in the two-level pairing model is investigated in terms of the equilibrium and the small fluctuation around it. The basic idea is an extension of results presented in a previous paper by the present authors. In this investigation, the result obtained in the previous paper plays a central role: At the limit of the weak and the strong interaction strength, the results are in good agreement with the exact one. The former and the latter are calculated in the framework of the $su(2)\otimes su(1,1)$- and the $su(2)\otimes su(2)$-coherent state, respectively. On the basis of the above conclusion, the intermediate region for the interaction strength is described in terms of the idea of the interpolation and it is shown that the agreement of the result with the exact one is quite good.

description: Aims. Accretion and luminosity bursts triggered by three distinct mechanisms: the magnetorotational instability in the inner disk regions, clump infall in gravitationally fragmented disks and close encounters with an intruder star, were studied to determine the disk kinematic characteristics that can help to distinguish between these burst mechanisms. Methods. Numerical hydrodynamics simulations in the thin-disk limit were employed to model the bursts in disk environments that are expected for each burst mechanism. Results. We found that the circumstellar disks featuring accretion bursts can bear kinematic features that are distinct for different burst mechanisms, which can be useful when identifying the burst origin. The disks in the stellar encounter and clump-infall models are characterized by tens of percent deviations from the Keplerian rotation, whie the disks in the MRI models are characterized only a few percent deviation, which is mostly caused by the gravitational instability that fuels the MRI bursts. Velocity channel maps also show distinct kinks and wiggles, which are caused by gas disk flows that are peculiar to each considered burst mechanism. The deviations of velocity channels in the burst-hosting disks from a symmetric pattern typical of Keplerian disks are strongest for the clump-infall and collision models, and carry individual features that may be useful for the identification of the corresponding burst mechanism. The considered burst mechanisms produce a variety of light curves with the burst amplitudes varying in the Δm=2.5-3.7 limits, except for the clump-infall model where Δm can reach 5.4, although the derived numbers may be affected by a small sample and boundary conditions. Conclusions. Burst triggering mechanisms are associated with distinct kinematic features in the burst-hosting disks that may be used for their identification. Abridged.

description: JASMINE is a Japanese planned space mission that aims to reveal the formation history of our Galaxy and discover habitable exoEarths. For these objectives, the JASMINE satellite performs high-precision astrometric observations of the Galactic bulge and high-precision transit monitoring of M-dwarfs in the near-infrared (1.0-1.6 microns in wavelength). For feasibility studies, we develop an image simulation software named JASMINE-imagesim, which produces realistic observation images. This software takes into account various factors such as the optical point spread function (PSF), telescope jitter caused by the satellite's attitude control error (ACE), detector flat patterns, exposure timing differences between detector pixels, and various noise factors. As an example, we report a simulation for the feasibility study of astrometric observations using JASMINE-imagesim. The simulation confirms that the required position measurement accuracy of 4 mas for a single exposure of 12.5-mag objects is achievable if the telescope pointing jitter uniformly dilutes the PSF across all stars in the field of view. On the other hand, the simulation also demonstrates that the combination of realistic pointing jitter and exposure timing differences in the detector can significantly degrade accuracy and prevent achieving the requirement. This means that certain countermeasures against this issue must be developed. This result implies that this kind of simulation is important for mission planning and advanced developments to realize more realistic simulations help us to identify critical issues and also devise effective solutions.

Effect of Environmental Conditions on Flight Capacity in Mountain Pine Beetle (Coleoptera: Curculionidae: Scolytinae)
Creators: Wijeranthna, Asha

Publisher: name: University of Alberta Library
Year: 2020

Mountain pine beetle (Dendroctonus ponderosae Coleoptera: Curculionidae: Scolytinae) is a major pest of pine (Pinaceae) in western North America. Mountain pine beetle has an obligatory dispersal phase during which beetles fly in search of new hosts to colonize. Climatic factors may influence dispersal in the expanding geographic range of the mountain pine beetle. This study tests mountain pine beetle flight capacity in the laboratory under different abiotic conditions including temperature, light and wind speed. Beetle flight capacity was tested under different temperatures before and during flight and different light regimes in separate computer-linked flight mill bioassays. A wind tunnel experiment tested the effect of wind speed on beetle flight. Pre-flight temperature and temperature during flight did not affect beetle flight capacity (distance or duration). Beetles do, however, use more energy during flight at high temperatures, which could affect host colonization following dispersal by flight of mountain pine beetle in nature. Beetles fly a greater distance and longer duration during a long (18 h) than short (16 h) photophase, suggesting that increased day length with a northern range expansion could affect beetle flight capacity. Although wind speed does not affect flight probability or duration, it affects the number of flights and flight patterns of mountain pine beetles.

description: The results of Direct Numerical Simulations of the oscillatory flow over a cohesionless bed of spherical particles, mimicking sediment grains, are described. The flow around the sediment particles is explicitly computed by using the immersed boundary method, which allows the force and torque acting on the particles to be evaluated along with their dynamics. Different values of the Reynolds number and different values of the ratio between the grain size and the thickness of the boundary layer are considered such that the results are useful to quantify the sand transport generated by sea waves in the region offshore of the breaker line. Therefore, the results are used to test the capability of empirical sediment transport formulae to predict the sediment transport rate during the oscillatory cycle.

 Remarks. According to the original description and figures (Wu 1948: figs. 15–17), this species certainly belongs to Hemacroneuria. The only character that may contradict this placement is the presumed lack of an anterior ocellus, but similar intrageneric variability of presence and the lack of an anterior ocellus occur also in Sinacroneuria Yang & Yang, 1995 (Li et al. 2017). Distinctive specific characters in the male of H. spatulata are the well separated, rounded patches of sensilla basiconica on tergum 10 and the wide apices of the paraprocts.

description: Representations of the quantum superalgebra U_q[osp(1/2)] and their relations to the basic hypergeometric functions are investigated. We first establish Clebsch-Gordan decomposition for the superalgebra U_q[osp(1/2)] in which the representations having no classical counterparts are incorporated. Formulae for these Clebsch-Gordan coefficients are derived, and it is observed that they may be expressed in terms of the $Q$-Hahn polynomials. We next investigate representations of the quantum supergroup OSp_q(1/2) which are not well-defined in the classical limit. Employing the universal T-matrix, the representation matrices are obtained explicitly, and found to be related to the little Q-Jacobi polynomials. Characteristically, the relation Q = -q is satisfied in all cases. Using the Clebsch-Gordan coefficients derived here, we construct new noncommutative spaces that are covariant under the coaction of the even dimensional representations of the quantum supergroup OSp_q(1/2).

description: Self-similar shock solutions in spherically symmetric polytropic gas flows are constructed and analyzed in contexts of proto-star formation processes. Among other possible solutions, we model a similarity shock across the sonic critical curve with an inner free-fall core collapse and a simultaneous outer expansion of the extended envelope; the separation or stagnation surface between these two flow zones travels outwards in a self-similar manner at a variable speed. One readily obtains accretion shock solutions. Semi-complete self-similar solutions across the sonic critical curve either once or twice without shocks can also be constructed. Features of star formation clouds of our polytropic model include the mass density scaling in the outer flow zone $ρ\propto r^{-2/(2-γ)}$, the temperature scalings of the inner flow zone $T\propto r^{-3(γ-1)/2}$ and of the outer flow zone $T\propto r^{-2(γ-1)/(2-γ)}$, and the variable central mass accretion rate $\dot{M}=k^{3/2}t^{(3-3γ)}m_0/G$ where $γ$ is the polytropic index, $k$ is a constant, $m_0$ is the core mass, and $G$ is the gravitational constant. Spectral line profiles characteristic of the `envelope expansion with core collapse' (EECC) shock solutions are expected. Random magnetic field permeated in a partially ionized cloud can be incorporated into this theoretical polytropic model framework. We discuss briefly our results in context of the oft-observed starless B335 cloud system as an example.

description: We study the possible covariant Lagrangians that describe the propagation of pure spin-3/2 particles. We show that, apart from the well-known Rarita-Schwinger Lagrangian, there is another possibility where the field is described by a gamma-traceless combination and that both Lagrangians yield the same physical predictions for the interaction of conserved sources. We also prove that for the case when the spin-2 field is described by a traceless field, there is no possible spin-3/2 action that makes the system supersymmetric. Nevertheless, the interaction between this field andthe spin-3/2 field may be possible.

Effect of semiochemical exposure on flight propensity and flight capacity of Dendroctonus ponderosae in laboratory bioassays
Creators: Jones, Kelsey L.
Evenden, Maya L.
Publisher: name: University of Alberta Library
Year: 2021

During flight, insect herbivores respond to volatile organic compounds (VOCs) released by host and non-host plants or conspecifics. Dendroctonus ponderosae uses chemical cues including host and non-host VOCs, as well as aggregation pheromones to navigate through the environment and find a suitable reproductive host. The dispersal flight distance of D. ponderosae from its natal host to its reproductive host varies widely, even within populations of beetles. Beetle energetics do not entirely explain this flight variation. In this study, we test the effect of beetle exposure to semiochemical cues before and during flight on subsequent flight propensity (the likelihood of flight initiation) and flight capacity (the distance and velocity of flight) using computer-linked flight mills. Exposure to host volatiles before flight interacts with beetle pre-flight weight to influence subsequent flight capacity of female but not male beetles. Female beetles flew further and faster following exposure to their aggregation pheromone, trans-verbenol. Flight of female beetles was reduced when they were exposed to volatiles from the non-host, Populus tremuloides, during flight. This study is the first to indicate that semiochemical cues not only influence beetle orientation during flight but also flight capacity of D. ponderosae. These results provide baseline information on the effect of environmental cues on dispersal by flight of D. ponderosae.
Icelandic women’s identifications of stressors and social support in the diagnostic phase of breast cancer

description: Breast cancer is the most common cancer among women. Approximately one in ten Icelandic women will develop breast cancer during her lifetime. Women cope with breast cancer in a wide variety of ways. Social support is an important coping resource and is seen as mediating the effects of stress on individual's well-being and adjustment. The purpose of this descriptive exploratory research was to describe the nature of stressors Icelandic women identify in the diagnostic phase of breast cancer, what sources of social support they draw upon, and their satisfaction with the social support they receive. Lazarus and Folkman's (1984) theory of stress, appraisal, and coping was used as a theoretical framework for the study. Semi-structured interviews were conducted with twelve women in the diagnostic phase of breast cancer. The diagnostic phase of breast cancer is a very stressful time in women's lives. Women experience the possibility of having cancer as an enormous threat, characterized by emotions like fear, anger, anxiety, restlessness, and sense of floating in the air. Women use emotion-focused coping throughout the diagnostic phase and, additionally, problem-focused coping after the diagnosis. Social support was a fundamental coping resource. Emotional support from husbands, family, and close friends was of utmost importance. Health professionals were not only the most important source of informational support but also a valuable source of emotional support. Acts people intended to be supportive, were in some cases perceived by the women as negative and a source of stress in themselves. Research findings define the supportive roles Icelandic health professionals should play in the diagnostic phase of breast cancer. Findings also provide a framework for further research on social support and breast cancer.

description: Use case modeling is very popular to represent the functionality of the system to be developed, and it consists of two parts: use case diagram and use case description. Use case descriptions are written in structured natural language (NL), and the usage of NL can lead to poor descriptions such as ambiguous, inconsistent and/or incomplete descriptions, etc. Poor descriptions lead to missing requirements and eliciting incorrect requirements as well as less comprehensiveness of produced use case models. This paper proposes a technique to automate detecting bad smells of use case descriptions, symptoms of poor descriptions. At first, to clarify bad smells, we analyzed existing use case models to discover poor use case descriptions concretely and developed the list of bad smells, i.e., a catalogue of bad smells. Some of the bad smells can be refined into measures using the Goal-Question-Metric paradigm to automate their detection. The main contribution of this paper is the automated detection of bad smells. We have implemented an automated smell detector for 22 bad smells at first and assessed its usefulness by an experiment. As a result, the first version of our tool got a precision ratio of 0.591 and recall ratio of 0.981.

description: A semiclassical theory of chaotic atomic transport in a one-dimensional nondissipative optical lattice is developed. Using the basic equations of motion for the Bloch and translational atomic variables, we derive a stochastic map for the synchronized component of the atomic dipole moment that determines the center-of-mass motion. We find the analytical relations between the atomic and lattice parameters under which atoms typically alternate between flying through the lattice and being trapped in the wells of the optical potential. We use the stochastic map to derive formulas for the probability density functions (PDFs) for the flight and trapping events. Statistical properties of chaotic atomic transport strongly depend on the relations between the atomic and lattice parameters. We show that there is a good quantitative agreement between the analytical PDFs and those computed with the stochastic map and the basic equations of motion for different ranges of the parameters. Typical flight and trapping PDFs are shown to be broad distributions with power law ``heads'' with the slope -1.5 and exponential ``tails''. The lengths of the power law and exponential parts of the PDFs depend on the values of the parameters and can be varied continuously. We find analytical conditions, under which deterministic atomic transport has fractal properties, and explain a hierarchical structure of the dynamical fractals.

description: In contrast to great success of memory-consuming face editing methods at a low resolution, to manipulate high-resolution (HR) facial images, i.e., typically larger than 7682 pixels, with very limited memory is still challenging. This is due to the reasons of 1) intractable huge demand of memory; 2) inefficient multi-scale features fusion. To address these issues, we propose a NOVEL pixel translation framework called Cooperative GAN(CooGAN) for HR facial image editing. This framework features a local path for fine-grained local facial patch generation (i.e., patch-level HR, LOW memory) and a global path for global lowresolution (LR) facial structure monitoring (i.e., image-level LR, LOW memory), which largely reduce memory requirements. Both paths work in a cooperative manner under a local-to-global consistency objective (i.e., for smooth stitching). In addition, we propose a lighter selective transfer unit for more efficient multi-scale features fusion, yielding higher fidelity facial attributes manipulation. Extensive experiments on CelebAHQ well demonstrate the memory efficiency as well as the high image generation quality of the proposed framework.

description: The zeroth law of black hole mechanics is an assertion of constancy of the surface gravity on a stationary Killing horizon. The Hawking temperature of the black hole horizon is proportional to the surface gravity. Therefore, the constancy of the surface gravity is reminiscent of the zeroth law of ordinary thermodynamics. In this work, we provide a proof of the zeroth law in Lanczos-Lovelock theories of gravity, where the Einstein Hilbert action is supplemented by higher curvature terms.

description: We introduce new algorithms for computing non-termination sensitive control dependence (NTSCD) and decisive order dependence (DOD). These relations on control flow graph vertices have many applications including program slicing and compiler optimizations. Our algorithms are asymptotically faster than the current algorithms. We also show that the original algorithms for computing NTSCD and DOD may produce incorrect results. We implemented the new as well as fixed versions of the original algorithms for the computation of NTSCD and DOD and we experimentally compare their performance and outcome. Our algorithms dramatically outperform the original ones.

description: We present a measurement of the systemic proper motion of the Small Magellanic Cloud (SMC) made using the Advanced Camera for Surveys (ACS) on the \textit{Hubble Space Telescope} (\textit{HST}). We tracked the SMC's motion relative to 4 background QSOs over a baseline of approximately 2 years. The measured proper motion is : $μ_W = -1.16 \pm 0.18 \masyr, μ_N = -1.17 \pm 0.18 \masyr$. This is the best measurement yet of the SMC's proper motion. We combine this new result with our prior estimate of the proper motion of the Large Magellanic Cloud (LMC) from the same observing program to investigate the orbital evolution of both Clouds over the past 9 Gyr. The current relative velocity between the Clouds is $105 \pm 42 \kms$. Our investigations of the past orbital motions of the Clouds in a simple model for the dark halo of the Milky Way imply that the Clouds could be unbound from each other. However, our data are also consistent with orbits in which the Clouds have been bound to each other for approximately a Hubble time. Smaller proper motion errors and better understanding of the LMC and SMC masses would be required to constrain their past orbital history and their bound vs. unbound nature unambiguously. The new proper motion measurements should be sufficient to allow the construction of improved models for the origin and properties of the Magellanic Stream. In turn, this will provide new constraints on the properties of the Milky Way dark halo.

Prediction and Inference: From Models and Data to Artificial Intelligence
Creators: name: Gammaitoni, Luca

description: In this paper we present a discussion of the basic aspects of the well-known problem of prediction and inference in physics, with specific attention to the role of models, the use of data and the application of recent developments in artificial intelligence. By focussing in the time evolution of dynamic system, it is shown that main difficulties in predictions arise due to the presence of few factors as: the occurrence of chaotic dynamics, the existence of many variables with very different characteristic time-scales and the lack of an accurate understanding of the underlying physical phenomena. It is shown that a crucial role is assigned to the preliminary identification of the proper variables, their selection and the identification of an appropriate level of description (coarse-graining procedure).

Functional characterization of mfs (2) 31 : a recessive supressor of position effect variegation
Creators: name: Burr, Roderick H. L.
Publisher: name: University of British Columbia
Year: 2009

description: The Drosophila melanogaster gene, mfs(2)31, is a recessive suppressor of position effect variegation (PEV) and has two open reading frames (ORFs) putatively derived from a single heterogeneous nuclear RNA (hnRNA). The coding region of Intronic Centrosomal Protein (ICP) is located in the first intron of the ubiquitin 80 amino acid fusion protein (DUb80) transcript, and is known to be liberated as a 1.2 Kb polyadenylated mRNA. Antibodies raised against the C-terminal 85 amino acids of ICP were used as a reagent for western blotting and indirect immunofluorescent staining of Drosophila embryos and HeLa cells. ICP was found to co-localize with p- tubulin in a Triton X-100® resistant compartment of both the Drosophila embryonic centrosome, and the HeLa cell centrosome. ICP was also localized to small, discrete, Triton X-100® resistant 'flecks' within HeLa cell nuclei in a pattern suggestive of the nuclear scaffold. These data suggest that ICP is involved in modulating nuclear and cytoplasmic microtubule dynamics throughout the cell cycle.
Continuous weak measurement and feedback control of a solid-state charge qubit: physical unravelling of non-Lindblad master equation

description: Conventional quantum trajectory theory developed in quantum optics is largely based on the physical unravelling of Lindbald-type master equation, which constitutes the theoretical basis of continuous quantum measurement and feedback control. In this work, in the context of continuous quantum measurement and feedback control of a solid-state charge qubit, we present a physical unravelling scheme of non-Lindblad type master equation. Self-consistency and numerical efficiency are well demonstrated. In particular, the control effect is manifested in the detector noise spectrum, and the effect of measurement voltage is discussed.

The systematics of Rocky Mountain Maple, Acer Glabrum Torr
Creators: name: Justice, Douglas Edward Clive
Publisher: name: University of British Columbia
Year: 2009

description: This study was undertaken to determine the most appropriate infraspecific taxonomy for Acer glabrum, as a review of the recent literature showed that the biological and taxonomic validity of the infraspecific taxa of Acer glabrum is not clear. This study involved field and herbarium studies, morphometric analysis, common garden transplant experiments and foliar flavonoid analysis. Field and herbarium studies showed that subsp. siskiyouense, var. greenei and var. tripartitum, names common in the literature, do not represent valid taxa. Varieties diffusum, douglasii, glabrum, neomexicanum, and torreyi are recognized, and have distinguishing leaf morphological characters that are correlated with more or less discrete geographical ranges. Morphometric analysis showed that leaf morphology is geographically correlated, but some numerical methods are not able to discriminate all taxa. Transplant experiments suggest that the distinctive morphologies of the early leaves of individual taxa are genetically fixed, and that late leaves, subject to environmental constraints, all tend toward a single morphology. Flavonoid analysis showed that there is no variation within or among the infraspecific taxa. The presence of flavanones strengthens the presumed close relationships between sections Glabra, Arguta, Cissifolia and Indivisa.

description: Neutron star-white dwarf (NS-WD) binaries evolve into either ultra-compact X-ray binaries undergoing stable mass transfer or direct mergers by unstable mass transfer. While much attention has been on gravitational wave (GW) emissions from NS-WD binaries with the former evolutionary pathway, this work explores GW emissions related to {\em r}-mode instability of the accreting NSs in NS-WD mergers particularly with WD's mass $\gtrsim 1M_{\odot}$. Due to considerably high accretion rates, the GW emissions associated with both {\em r}-modes and magnetic deformation intrinsically induced by {\em r}-modes presented in this work are much stronger than those in NS-WD binaries categorized as intermediate-mass or low-mass X-ray binaries, rendering them interesting sources for the advanced Laser Interferometer Gravitational Wave Observatory and upcoming Einstein Telescope. Moreover, these strong GW emissions might accompany some intriguing electromagnetic emissions such as peculiar long gamma-ray bursts (LGRBs), fast blue optical transients including kilonova-like emissions associated with peculiar LGRBs, and/or fast radio bursts.

description: Autophagy is an intracellular degradation process that is mediated by de novo formation of autophagosomes. Autophagosome formation involves dynamic morphological changes; a disk-shaped membrane cisterna grows, bends to become a cup-shaped structure, and finally develops into a spherical autophagosome. We have constructed a theoretical model that integrates the membrane morphological change and entropic partitioning of putative curvature generators, which we have used to investigate the autophagosome formation process quantitatively. We show that the membrane curvature and the distribution of the curvature generators stabilize disk- and cup-shaped intermediate structures during autophagosome formation, which is quantitatively consistent with in vivo observations. These results suggest that various autophagy proteins with membrane curvature-sensing properties control morphological change by stabilizing these intermediate structures. Our model provides a framework for understanding autophagosome formation.

Time-Aware Models for Software Effort Estimation

description: It seems logical to assert that the dynamic nature of software engineering practice would mean that software effort estimation (SEE) modelling should take into account project start and completion dates. That is, we should build models for future projects based only on data from completed projects; and we should prefer data from recent similar projects over data from older similar projects. Research in SEE modelling generally ignores these recommendations. In this study two different model development approaches that take project timing into account are applied to two publicly available datasets and the outcomes are compared to those drawn from three baseline (non-time-aware) models. Our results indicate: that it is feasible to build accurate effort estimation models using project timing information; that the models differ from those built without considering time, in terms of the parameters included and their weightings; and that there is no statistical significance difference as to which of the two model building approaches is superior in terms of accuracy.

description: We present a dynamical spectral model for Large Eddy Simulation of the incompressible magnetohydrodynamic (MHD) equations based on the Eddy Damped Quasi Normal Markovian approximation. This model extends classical spectral Large Eddy Simulations for the Navier-Stokes equations to incorporate general (non Kolmogorovian) spectra as well as eddy noise. We derive the model for MHD and show that introducing a new eddy-damping time for the dynamics of spectral tensors in the absence of equipartition between the velocity and magnetic fields leads to better agreement with direct numerical simulations, an important point for dynamo computations.
