description: Concomitant with the evolution of biological diversity must have been the evolution of mechanisms that facilitate evolution, due to the essentially infinite complexity of protein sequence space. We describe how evolvability can be an object of Darwinian selection, emphasizing the collective nature of the process. We quantify our theory with computer simulations of protein evolution. These simulations demonstrate that rapid or dramatic environmental change leads to selection for greater evolvability. The selective pressure for large scale genetic moves, such as DNA exchange, becomes increasingly strong as the environmental conditions become more uncertain. Our results demonstrate that evolvability is a selectable trait and allow for the explanation of a large body of experimental results.

The progress in reducing the under-5 mortality rate (U5MR) since 1990 has been remarkable but uneven within countries between urban and rural populations. While trend U5MR estimates have been published frequently, an analysis of U5MR by urban and rural area has not been available across countries over time. In this paper, we provide annual estimates of U5MR among urban residence for 109 countries from 1990 to 2018 using a Bayesian time series model and assess the corresponding uncertainty. The analyses are based on an extensive database complied from surveys (including DHS, MICS, RHS, PAPFAM, PAPCHILD), censuses, and vital registration system. We present results for selected countries and identify country-years with the highest disparities in U5MR between urban area and national level.

description: The expanding population and rapid urbanisation, in particular in the Global South, are leading to global challenges on resource supply stress and rising waste generation. A transformation to resource-circular systems and sustainable recovery of carbon-containing and nutrient-rich waste offers a way to tackle such challenges. Eco-industrial parks have the potential to capture symbioses across individual waste producers, leading to more effective waste-recovery schemes. With whole-system design, economically attractive approaches can be achieved, reducing the nvironmental impacts while increasing the recovery of high-value resources. In this paper, an optimisation framework is developed to enable such design, allowing for wide ranging treatment options to be considered capturing both technological and fnancial detail. As well as technology selection, the framework also accounts for spatial aspects, with the design of suitable transport networks playing a key role. A range of scenarios are investigated using the network, highlighting the multi-faceted nature of the problem. The need to incorporate the impact of resource recovery at the design stage is shown to be of particular importance.

Using tissue doppler imaging during exercise to assess ventricular function and wall motion in childhood survivors of acute lymphoblastic leukemia
Creators: name: De Souza, Astrid-Marie
Publisher: name: University of British Columbia
Year: 2009

description: BACKGROUND: Childhood survivors of Acute Lymphoblastic Leukemia (ALL) may be at risk of cardiotoxicity as a consequence of their treatment with anthracyclines. Stress echocardiography has been well established as a method to detect latent cardiac dysfunction, indicative of cardiotoxicity. Tissue Doppler Imaging (TDI) is a new echocardiographic technique that can be incorporated into current stress echocardiography protocols to potentially enhance our ability to detect early changes in cardiac function in ALL patients treated with anthracyclines. PURPOSE: To determine if ALL patients have abnormal wall motion responses to exercise. METHODS: Thirteen ALL patients (11 yrs; 9-14 yrs) and fourteen healthy children (10.5 yrs; 9-16 yrs) were studied. ALL patients were treated with a median cumulative anthracycline dose of 150 mg/m² (150-175 mg/m²). TDI was performed during semi-supine cycle ergometry at rest, peak exercise, immediately post- and 3 minutes post-exercise. The parasternal long axis (posterior wall=POS) and apical 4-chamber (lateral wall=LAT, interventricular septum=SEP, and right ventricular wall=RV) views were used to obtain measurements. Tissue velocities (S' E', A'), strain (ε[sub sys]), and tissue tracking (TT) were measured. TDI analyses were performed off-line. Oxygen capacity (VO₂) was measured concurrently. A Wilcoxon-Rank Sum test was used to determine whether there were differences between ALL patients and controls and between each stage. Data was analyzed using SPSS 12.0 Statistical Software (SPSS Inc., Chicago, IL). RESULTS: No significant differences were found between ALL patients and controls at rest, peak, immediately post-, and 3 minutes post-exercise for all TDI variables. S' and A' significantly increased in all walls, in both groups. E' significantly increased in the POS and RV, but not in the LAT and SEP. Strain did not increase with exercise in any of the segments evaluated. A significant increase in TT was only seen in the POS wall of the controls (p≤0.003); however, values were approaching statistical significance in the POS of ALL patients (p=0.004). Peak VO₂ was similar between groups. CONCLUSIONS: I have shown that TDI variables and VO₂ peak are similar in ALL patients and controls. Further studies are needed to determine the clinical usefulness of TDI during stress echocardiography.

We implemented Bayesian methods for probabilistic sex ratio at birth (SRB) estimation and projection for all countries based on an extensive database with data from vital registration systems, censuses, and surveys. We identified countries at risk of SRB inflation due to sex-selective abortion in the past/current/future. We modeled SRB regional biological norms, fluctuation around regional norms, and SRB inflation. For countries at risk of SRB inflation without empirical evidence of past inflation, projections with and without future inflation were constructed. We found that the past/ongoing SRB inflation occurred mostly in Southern Asia and Eastern Asia, resulting in 9.3 (95% uncertainty interval [5.7; 13.7]) and 11.2 [7.2; 15.7] million missing female births during 1970–2015. Under the scenario that all countries at risk of SRB inflation will experience inflation, the estimated number of missing female births globally between 2016–2100 is 8.8 [6.5; 12.7] million, with 94.2% in Sub-Saharan Africa.

description: Machine learning potentials (MLPs) are becoming powerful tools for performing accurate atomistic simulations and crystal structure optimizations. An approach to developing MLPs employs a systematic set of polynomial invariants including high-order ones to represent the neighboring atomic density. In this study, a formulation of the polynomial invariants is extended to the case of multicomponent systems. The extended formulation is more complex than the formulation for elemental systems. This study also shows its application to Ti-Al binary system. As a result, an MLP with the lowest error and MLPs with high computational cost performance are selected from the many MLPs developed systematically. The predictive powers of the developed MLPs for many properties, such as the formation energy, elastic constants, thermodynamic properties, and mechanical properties, are examined. The MLPs exhibit high predictive power for the properties in a wide variety of ordered structures. The present scheme should be systematically applicable to other multicomponent systems.

description: Survival data are most frequently analyzed by the intention-to-treat principle. However, presenting a compliance-adjusted analysis alongside the primary analysis can provide an insight into the effect of the treatment for those individuals actually complying with their randomized intervention. There are a number of methods for this type of analysis. Loeys and Goetghebeur (2003) use proportional hazards techniques to provide an estimate of the treatment effect for compliers when compliance is measured on an all-or-nothing scale. This methodology is here made available through a new Stata command, stcomply.

description: We calculate neutron multiplicities from fission fragments with specified mass numbers for events having a specified total fragment kinetic energy. The shape evolution from the initial compound nucleus to the scission configurations is obtained with the Metropolis walk method on the five-dimensional potential-energy landscape, calculated with the macroscopic-microscopic method for the three-quadratic-surface shape family. Shape-dependent microscopic level densities are used to guide the random walk, to partition the intrinsic excitation energy between the two proto-fragments at scission, and to determine the spectrum of the neutrons evaporated from the fragments. The contributions to the total excitation energy of the resulting fragments from statistical excitation and shape distortion at scission is studied. Good agreement is obtained with available experimental data on neutron multiplicities in correlation with fission fragments from $^{235}$U(n$_{\rm th}$,f). At higher neutron energies a superlong fission mode appears which affects the dependence of the observables on the total fragment kinetic energy.

description: We study higher twist corrections to the perturbative QCD cross sections for ep deep inelastic scattering and the Drell-Yan lepton pair production in pp collision. The corrections arise due to the initial state interaction of the active quarks with the spectator partons. The effect of this interaction is calculated by dressing the incoming quark lines with phenomenological single parameter Breit-Wigner spectral functions and taking into account the full off-shell kinematics. The quark width in the proton is estimated by analyzing the data on Drell-Yan triple differential cross section from the experiment E866 at Fermilab.

The climatic suitability of New Zealand for Cirsium arvense and its biological control agent Cassida rubiginosa

description: The leaf-feeding beetle, Cassida rubiginosa, was introduced into New Zealand from Europe in 2007 as a biological control agent for Cirsium arvense (Californian thistle) and is now widely distributed. To determine the extent to which geographically variable climate might explain its observed sporadic impact, we developed a climate-niche model for each of the species using CLIMEX. The models reveal that the climate throughout most of New Zealand is variably suitable for both species, although everywhere relatively less suitable for the beetle. However, we found no evidence that this climate suitability bias favouring the thistle explains the sporadic impact of the beetle. First, 64 geographically separate beetle populations classified by field observers according to their impact on the thistle (‘none’, n = 29; ‘low’, n = 22; ‘high’, n = 13) showed no relationship with the modelled climate suitability (Ecoclimatic Index) of their locations for either the beetle or the thistle. Second, the two models reveal a similar climate suitability bias favouring the thistle throughout much of the species’ ‘eco-climatic suitability space’ in their native range (Eurasia) where the beetle is a widespread natural enemy of the thistle. Hypothetical explanations for the sporadic impact of the beetle in New Zealand are explored, including lack of suitable overwintering habitat, predation, and incompatible thistle control operations. We conclude that in general, climate suitability, while a necessary condition, is alone insufficient for the success of a weed biological control program, and that non-climatic habitat factors may often explain spatially patchy impacts of natural enemies such as C. rubiginosa.
Nonlinear Schrödinger Equation with a White-Noise Potential: Phase-space Approach to Spread and Singularity

Year: 2005
Subjects: subject: Chaotic Dynamics (nlin.CD)

description: We propose a phase-space formulation for the nonlinear Schrödinger equation with a white-noise potential in order to shed light on two issues: the rate of spread and the singularity formation in the average sense. Our main tools are the energy law and the variance identity. The method is completely elementary. For the problem of wave spread, we show that the ensemble-averaged dispersion in the critical or defocusing case follows the cubic-in-time law while in the supercritical and subcritical focusing cases the cubic law becomes an upper and lower bounds respectively. We have also found that in the critical and supercritical focusing cases the presence of a white-noise random potential results in different conditions for singularity-with-positive-probability from the homogeneous case but does not prevent singularity formation. We show that in the supercritical focusing case the ensemble-averaged self-interaction energy and the momentum variance can exceed any fixed level in a finite time with positive probability.

description: Matching is occasionally used in cohort studies; examples include studies of twins and some studies of traffic crashes. Analysis of matched cohort data is not discussed in many textbooks or articles and is not mentioned in the Stata manuals. Risk ratios can be estimated using matched-pair cohort data with Stata’s mcc command. We describe a new command, csmatch, which can produce these risk ratios and is often more convenient. We briefly review flexible regression methods that can estimate risk ratios in matched cohort data: conditional Poisson regression and some versions of Cox regression.

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: In a spin field effect transistor, a magnetic field is inevitably present in the channel because of the ferromagnetic source and drain contacts. This field causes random unwanted spin precession when carriers interact with non-magnetic impurities. The randomized spins lead to a large leakage current when the transistor is in the ``off''-state, resulting in significant standby power dissipation. We can counter this effect of the magnetic field by engineering the Dresselhaus spin-orbit interaction in the channel with a backgate. For realistic device parameters, a nearly perfect cancellation is possible, which should result in a low leakage current.
description: To appear in Physica E. The revised version has additional material which addresses the issue of which way the contacts should be magnetized in a Spin Field Effect Transistor. This was neither addressed in the previous version, nor in the upcoming journal paper

description: Data structure has a dramatic impact on the properties of neural networks, yet its significance in the established theoretical frameworks is poorly understood. Here we compute the Vapnik-Chervonenkis entropy of a kernel machine operating on data grouped into equally labelled subsets. At variance with the unstructured scenario, entropy is non-monotonic in the size of the training set, and displays an additional critical point besides the storage capacity. Remarkably, the same behavior occurs in margin classifiers even with randomly labelled data, as is elucidated by identifying the synaptic volume encoding the transition. These findings reveal aspects of expressivity lying beyond the condensed description provided by the storage capacity, and they indicate the path towards more realistic bounds for the generalization error of neural networks.

We provide the complete lists of four forbidden minors and eleven forbidden subdivisions for the toroidal graphs with no $K_{3,3}$'s and prove that the lists are sufficient.

description: Batched sparse (BATS) codes were proposed as a reliable communication solution for networks with packet loss. In the finite-length regime, the error probability of BATS codes under belief propagation (BP) decoding has been studied in the literature and can be analyzed by recursive formulae. However, all existing analyses have not considered precoding or have treated the BATS code and the precode as two separate entities. In this paper, we analyze the word-wise error probability of finite-length BATS codes with a precode under joint decoding, including BP decoding and maximum-likelihood (ML) decoding. The joint BP decoder performs peeling decoding on a joint Tanner graph constructed from both the BATS and the precode Tanner graphs, and the joint ML decoder solves a single linear system with all linear constraints implied by the BATS code and the precode. We derive closed-form upper bounds on the error probability for both decoders. Specifically, low-density parity-check (LDPC) precodes are used for BP decoding, and any generic precode can be used for ML decoding. Even for BATS codes without a precode, the derived upper bound for BP decoding is more accurate than the approximate recursive formula, and easier to compute than the exact recursive formula. The accuracy of the two upper bounds has been verified by many simulation results. Based on the two upper bounds, we formulate an optimization problem to optimize the degree distribution of LDPC-precoded BATS codes, which improves BP performance, ML performance, or both. In our experiments, to transmit 128 packets over a line network with packet loss, the optimized LDPC-precoded BATS codes reduce the transmission overhead to less than 50% of that of standard BATS codes under comparable decoding complexity constraints.

A priori derivation of the discrete lattice BGK Boltzmann equation with a spatially and temporally dependent relaxation time parameter, which is used to represent the averaged flow field, from its corresponding continuous form is given. The averaged behavior of the turbulence field is represented by the standard {\it k-$ε$} turbulence model and computed using a finite-volume scheme on non-uniform grids. Computed results are compared with analytical solutions, experimental data and results of other computational methods. Satisfactory agreement is shown.

description: in West Sumatra, Indonesia, killed more than 1200 people. Thousands of damaged houses, buildings and infrastructure have been reported with low to severe damage level. This research reports the effect of the Padang earthquake in terms of building damages and landslides that occured in the city of Padang, Padang Pariaman, Pariaman and Agam. Analysis on earthquake effects was carried out based on the geology, geotechnical, building damages and geohazards data collected from various sources and field works in affected areas. Results from field work showed that damages on the building structures in Padang and Padang Pariaman was due to the quality of construction which did not meet the building code and standard requirements, and the effect of geological conditions, i.e., ground amplification on deep layer of alluvial deposit. Some observed damage in the buildings were related to the building location constructed on the fault lines and soil or rock layers discontinuity. From the site visit, it was found that landslide cases which occurred in Pariaman and Agam after the earthquake were caused by the topography, geomorphology of area and steep slopes. Further studies should be carried out for hazard risks identification and assessment in order to prepare for future earthquakes.

description: We present the Bethe ansatz solution for the discrete time zero range and asymmetric exclusion processes with fully parallel dynamics. The model depends on two parameters: $p$, the probability of single particle hopping, and $q$, the deformation parameter, which in the general case, $|q|<1$, is responsible for long range interaction between particles. The particular case $q=0$ corresponds to the Nagel-Schreckenberg traffic model with $v_{\mathrm{max}}=1$. As a result, we obtain the largest eigenvalue of the equation for the generating function of the distance travelled by particles. For the case $q=0$ the result is obtained for arbitrary size of the lattice and number of particles. In the general case we study the model in the scaling limit and obtain the universal form specific for the Kardar-Parisi-Zhang universality class. We describe the phase transition occurring in the limit $p\to 1$ when $q<0$.

В исследовании с помощью номотетических методов установлено, что большинство опрошенных тренеров относятся к андрогинному гендерному типу личности и придерживаются в своей педагогической деятельности стилей, направленных как на результат, так и на процесс обучения.
Attention and the visuomotor system : can the dorsal stream process two action targets simultaneously?

description: The processing of visual information for the purpose of executing goal-directed actions is, according to dual-stream theory, carried out by the 'dorsal stream', an occipito-parietal route of visual processing in the primate brain. The current study investigated the attentional capacity of the dorsal stream: Can it attend to more than one action target at a time? Two experiments were carried out to address this question. In the first experiment, 11 healthy participants executed fast sequential aiming movements in which they tapped two horizontally aligned targets. On a given trial, either, or both, of the targets could jump to a new location. This perturbation was tied to the participant's saccade so that the target movement would not be consciously perceived, and the targets were extinguished 20ms after the perturbation. The targets were, therefore, no longer visible when the eyes landed. The results of Experiment 1 revealed that participants consistently adjusted their aiming movements in accordance with the perturbations, regardless of which target jumped. Experiment 2 employed a similar protocol, but added a 3sec delay between the saccadically-triggered double-step and the onset of the participant's movement. This manipulation was intended to eliminate dorsal-stream involvement in the guidance of the movement, as the dorsal-stream is thought to retain visual information for, at most, 2sec. After this 2sec period, movement guidance should rely on a ventrally-stored conscious visual representation. We hypothesized, therefore, that the delay would eliminate the effect observed in Experiment 1. Nine healthy participants took part in Experiment 2, and, contrary to our hypothesis, produced aiming movements very similar to those of Experiment 1. The results of Experiments 1 and 2 demonstrate that location information about both targets in a sequential aiming movement is processed simultaneously and that this information can be used to update the movement. However, the results do not allow us to confidently conclude that the dorsal stream can process two targets simultaneously. Potential problems with the saccadically-triggered double-step design as a means of investigating dorsal stream processing are discussed.

description: Intense light-field can dress both Bloch electrons inside crystals and photo-emitted free electrons in the vacuum, dubbed as Floquet and Volkov states respectively. These quantum states can further interfere coherently, modulating light-field dressed states. Here, we report experimental evidence of the Floquet-Volkov interference in a semiconductor - black phosphorus. A highly asymmetric modulation of the spectral weight is observed for the Floquet-Volkov states, and such asymmetry can be further controlled by rotating the pump polarization. Our work reveals the quantum interference between different light-field dressed electronic states, providing insights for material engineering on the ultrafast timescale.

description: This paper presents an implementation of matching estimators for average treatment effects in Stata. The nnmatch command allows you to estimate the average effect for all units or only for the treated or control units; to choose the number of matches; to specify the distance metric; to select a bias adjustment; and to use heteroskedastic-robust variance estimators.
PET-enabled Dual-Energy CT: Image Reconstruction and A Proof-of-Concept Computer Simulation Study

description: Standard dual-energy computed tomography (CT) uses two different X-ray energies to obtain energy-dependent tissue attenuation information to allow quantitative material decomposition. The combined use of dual-energy CT and positron emission tomography (PET) may provide a more comprehensive characterization of disease states in cancer and many other diseases. However, the integration of dual-energy CT with PET is not trivial, either requiring costly hardware upgrade or increasing radiation dose. This paper proposes a novel dual-energy CT imaging method that is enabled by the already-available PET data on PET/CT. Instead of using a second X-ray CT scan with a different energy, this method exploits time-of-flight PET image reconstruction via the maximum likelihood attenuation and activity (MLAA) algorithm to obtain a 511 keV gamma-ray attenuation image from PET emission data. The high-energy gamma-ray CT image is then combined with the low-energy X-ray CT of PET/CT to provide a pair of dual-energy CT images. A major challenge with the standard MLAA reconstruction is the high noise present in the reconstructed 511 keV attenuation map, which does not compromise the PET activity reconstruction too much but significantly affects the performance of the gamma-ray CT for material decomposition. To overcome the problem, we further propose a kernel MLAA algorithm to exploit the prior information from the available X-ray CT image. We conducted a computer simulation to test the concept and algorithm for the task of material decomposition. The simulation results indicate that this PET-enabled dual-energy CT method is promising for quantitative material decomposition. The proposed method can be readily implemented on time-of-flight PET/CT scanners to enable simultaneous PET and dual-energy CT imaging.

description: The Great Barrier Reef (GBR) is a vast iconic environmental asset covering an area of approximately 35 million hectares. It is valued by people all over Australia, as well as overseas. Non-market values for the GBR will comprise both use and non-use values. The values of people who live closer to the GBR and who can visit it more frequently are likely to be higher than those who live further away. The aim of this study was to estimate the values to protect the health of the GBR at the national level and to examine the effects of distance decay on valuation estimates. A split-sample choice-modelling experiment was conducted in six locations: a regional town within the GBR catchment area (Townsville); Brisbane, the state capital approximately 450 km from the southern limit of the GBR; and four other capital cities (Sydney, Melbourne, Adelaide and Perth) ranging from 730 km to over 3600 km from Brisbane. The results indicate that the total national value for a 1 per cent improvement in the health of the GBR ranges from between a low of approximately $433.6 million to a high of $811.3 million, depending on the underlying assumptions made. There was some evidence of distance decay in values. Most decline occurred once outside the home state, and little further decline once away from the east coast. There was no evidence to suggest any difference in patterns of use and non-use values. The values of the potential future users were most influential in determining WTP estimates.

National-level estimates of the under-five mortality rate (U5MR) may mask disparities at the subnational level. We developed a Bayesian hierarchical time series model to assess disparities in the U5MR by household-level socioeconomic status (measured through wealth quintiles). In the model, country-specific ratios of wealth-quintile-specific U5MRs are modelled as the product of an expected ratio and a country-specific deviation from that expected ratio. We obtained quintile-specific estimates for 96 countries from 1990 (or the earliest year of data collection) to 2015 and pinpointed countries with unusually large or small disparities. We find that important differences exist between children from the poorest and richest households with respect to survival up to age five.

description: There is an ongoing policy debate regarding both how much government intervention there should be to protect ecosystems affected by agriculture, and how the costs of these interventions should be distributed across different interest groups. In accordance with the policy focus in most countries, the majority of the valuation literature on ecosystem services and agriculture estimates the benefits that managed agricultural landscapes can provide to the rest of society. We argue, however, that the efficiency and equity of policies for ecosystem services related to agriculture can be further enhanced by understanding the value and sources of ecosystem services that agricultural production receives. With this in mind, we survey studies and techniques for estimating the value of ecosystem services to agricultural production.

description: Ta films with tetragonal crystalline structure (beta-phase), deposited by magnetron sputtering on different substrates (steel, silicon and silicon dioxide), have been studied. In all cases, very highly preferred (001) orientation was observed in x-ray diffraction (XRD) measurements. All diffraction data revealed two weak reflections corresponding to d-spacing of 0.5272 and 0.1777 nm. The presence of the two peaks, attributed to (001) and (003) reflections, indicates that beta-Ta films exhibit a high preference for the space group of P-421m over P42/mnm, previously proposed for beta-Ta. Differences in relative intensities of (00l) reflections, calculated for single crystal beta-Ta sigma-type Frank-Kasper structure and those measured in the films, are attributed to defects in the films. Molecular dynamics simulations performed on tantalum clusters with six different initial configurations using the embedded-atom-method (EAM) potential revealed the stability of beta-Ta, which might explain its growth on many substrates under various deposition conditions.
