description: The process of charm quark fragmentation is studied using $D^{*\pm}$ meson production in deep-inelastic scattering as measured by the H1 detector at HERA. Two different regions of phase space are investigated defined by the presence or absence of a jet containing the $D^{*\pm}$ meson in the event. The parameters of fragmentation functions are extracted for QCD models based on leading order matrix elements and DGLAP or CCFM evolution of partons together with string fragmentation and particle decays. Additionally, they are determined for a next-to-leading order QCD calculation in the fixed flavour number scheme using the independent fragmentation of charm quarks to $D^{*\pm}$ mesons.

description: Analysis of inclusions in primitive meteorites reveals that several short-lived radionuclides (SLRs) with half-lives $0.1-100$ Myr existed in the early Solar System (ESS). We investigate the ESS origin of $^{107}$Pd, $^{135}$Cs, and $^{182}$Hf, which are produced by $slow$ neutron captures (the $s$-process) in asymptotic giant branch (AGB) stars. We modelled the galactic abundances of these SLRs using the OMEGA+ galactic chemical evolution (GCE) code and two sets of mass- and metallicity-dependent AGB nucleosynthesis yields (Monash and FRUITY). Depending on the ratio of the mean life $τ$ of the SLR to the average length of time between the formation of AGB progenitor $γ$, we calculate timescales relevant for the birth of the Sun. If $τ/γ\gtrsim2$, we predict self-consistent isolation times between 9 and 26 Myr by decaying the GCE predicted $^{107}$Pd/$^{108}$Pd, $^{135}$Cs/$^{133}$Cs, and $^{182}$Hf/$^{180}$Hf ratios to their respective ESS ratios. The predicted $^{107}$Pd/$^{182}$Hf ratio indicates that our GCE models are missing $9-73\%$ of $^{107}$Pd and $^{108}$Pd in the ESS. This missing component may have come from AGB stars of higher metallicity than those that contributed to the ESS in our GCE code. If $τ/γ\lesssim0.3$, we calculate instead the time ($T_{\rm LE}$) from the last nucleosynthesis event that added the SLRs into the presolar matter to the formation of the oldest solids in the ESS. For the 2 M$_\odot$, $Z=0.01$ Monash model we find a self-consistent solution of $T_{\rm LE}=25.5$ Myr.

description: Die Implementierung der Position der Gleichstellungsbeauftragten in öffentlichen Institutionen ist in der Regel gelungen. Funktionsträgerinnen auf diesen Posten gehören dabei mittlerweile nicht mehr zwingend einer gesellschaftspolitischen Bewegung an bzw. grenzen sich teilweise explizit von der Frauenrechtsbewegung ab. Darüber hinaus haben sich, beispielsweise durch die Etablierung von Vernetzungsstrukturen, Professionalisierungsprozesse vollzogen. Dennoch haftet der Funktion der Frauen- und Gleichstellungsbeauftragten das „Stigma des Feminismus“ an. Vor diesem Hintergrund stellt der Beitrag die Frage nach dem Zusammenspiel biografischer Verletzbarkeit und professionellen Handelns von Gleichstellungsakteurinnen. Stigmatisierungsprozesse in der Gleichstellungsarbeit werden dabei auf der Ebene interpretativer Interaktionsräume verortet und aus feministischer Perspektive betrachtet. Letztlich wird die Notwendigkeit eines reflexiven Stigmamanagements als biografisch dimensioniertes Professionalisierungsprojekt von Gleichstellungsakteurinnen identifiziert.

description: We will take a look at axion inflation in string theory, taking a somewhat eclectic approach guided by some mechanism classes and (semi-)explicit examples. Looking at models with either 1 or 2 axions, we will argue that (up to manifestly tuning for small-field models) inflation can arise from 2 different mechanisms - either monodromy, or hybrid inflation. Cautiously incorporating both known limits of top-down theory knowledge as well as bottom-up ‘effective quantum gravity’ conjectural constraints, should lead to a ‘theory error blob’ of CMB observable predictions describing the ‘mechanism equivalence class’. We outline this using harmonic hybrid inflation as a representative of 2-axion hybrid inflation, and then describe a systematic method of propagating the ‘theory error’ to observable predictions using machine learning and information geometry.

description: In recent years there has been significant fundamental research into phonon polaritons, owing to their ability to compress light to extremely small dimensions, low-losses, and ability to support anisotropic propagation. In this perspective, after briefly reviewing the present state of mid-infrared optoelectronics, we will assess the potential of phonon-polariton based nanophotonics for infrared (3-100$\mathrmμ$m) light sources, detectors and modulators. These will operate in the Reststrahlen region where conventional semiconductor light sources become ineffective. Drawing on the results from the past few years, we will sketch some promising paths to create such devices and we will evaluate their practical advantages and disadvantages when compared to other approaches to infrared optoelectronics.

description: An integrated clinical environment (ICE) enables the connection and coordination of the internet of medical things around the care of patients in hospitals. However, ransomware attacks and their spread on hospital infrastructures, including ICE, are rising. Often the adversaries are targeting multiple hospitals with the same ransomware attacks. These attacks are detected by using machine learning algorithms. But the challenge is devising the anti-ransomware learning mechanisms and services under the following conditions: (1) provide immunity to other hospitals if one of them got the attack, (2) hospitals are usually distributed over geographical locations, and (3) direct data sharing is avoided due to privacy concerns. In this regard, this paper presents a federated distributed integrated clinical environment, aka. FedDICE. FedDICE integrates federated learning (FL), which is privacy-preserving learning, to SDN-oriented security architecture to enable collaborative learning, detection, and mitigation of ransomware attacks. We demonstrate the importance of FedDICE in a collaborative environment with up to four hospitals and four popular ransomware families, namely WannaCry, Petya, BadRabbit, and PowerGhost. Our results find that in both IID and non-IID data setups, FedDICE achieves the centralized baseline performance that needs direct data sharing for detection. However, as a trade-off to data privacy, FedDICE observes overhead in the anti-ransomware model training, e.g., 28x for the logistic regression model. Besides, FedDICE utilizes SDN's dynamic network programmability feature to remove the infected devices in ICE.

description: A {\em k-generalized Dyck path} of length $n$ is a lattice path from $(0,0)$ to $(n,0)$ in the plane integer lattice $\mathbb{Z}\times\mathbb{Z}$ consisting of horizontal-steps $(k, 0)$ for a given integer $k\geq 0$, up-steps $(1,1)$, and down-steps $(1,-1)$, which never passes below the x-axis. The present paper studies three kinds of statistics on $k$-generalized Dyck paths: "number of $u$-segments", "number of internal $u$-segments" and "number of $(u,h)$-segments". The Lagrange inversion formula is used to represent the generating function for the number of $k$-generalized Dyck paths according to the statistics as a sum of the partial Bell polynomials or the potential polynomials. Many important special cases are considered leading to several surprising observations. Moreover, enumeration results related to $u$-segments and $(u,h)$-segments are also established, which produce many new combinatorial identities, and specially, two new expressions for Catalan numbers.

description: The recognition of entanglement states is a notoriously difficult problem when no prior information is available. Here, we propose an efficient quantum adversarial bipartite entanglement detection scheme to address this issue. Our proposal reformulates the bipartite entanglement detection as a two-player zero-sum game completed by parameterized quantum circuits, where a two-outcome measurement can be used to query a classical binary result about whether the input state is bipartite entangled or not. In principle, for an $N$-qubit quantum state, the runtime complexity of our proposal is $O(\text{poly}(N)T)$ with $T$ being the number of iterations. We experimentally implement our protocol on a linear optical network and exhibit its effectiveness to accomplish the bipartite entanglement detection for 5-qubit quantum pure states and 2-qubit quantum mixed states. Our work paves the way for using near-term quantum machines to tackle entanglement detection on multipartite entangled quantum systems.

description: We analyze the left-right asymmetry of pion production in semi-inclusive deep inelastic scattering (SIDIS) process of unpolarized charged lepton on transversely polarized nucleon target. Unlike available treatments, in which some specific weighting functions are multiplied to separate theoretically motivated quantities, we do not introduce any weighting function following the analyzing method by the E704 experiment. The advantage is that this basic observable is free of any theoretical bias, although we can perform the calculation under the current theoretical framework. We present numerical calculations at both HERMES kinematics for the proton target and JLab kinematics for the neutron target. We find that with the current theoretical understanding, Sivers effect plays a key role in our analysis.

Mentally retarded adults in the community: social policy and the normalization of services for deinstitutionalized adults
Creators: name: Eni, Godwin Onuoha
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to explore the nature and content of the social policy of "normalization" in community based services which have been used to meet the needs of deinstitutionalized mentally retarded adults. In the process it was hoped that data would be obtained to aid decision makers in planning community services for retarded adults. The study was directed to examine the relationship between the levels of normalization in services which had been provided for retarded adults who were discharged from the Provincial institution for mental retardation - Woodlands - under the medical administration of retardation services as well as after the assumption of same responsibility by the Ministry of Human Resources. These administrations represented the medical and the social systems of service delivery. "Normalization" had been adopted as "policy" soon after the transfer of responsibilities by the Ministries. Three areas of concern were examined: Levels of normalization of services; needs of subjects; and normalization as policy. These areas had been central to public discussion of retardation issues in British Columbia. In order to examine the three areas, normalization was defined in the Greater Vancouver Area of study using the explicit judgement of citizens and the implicit judgement of professionals. From their judgements, a criteria for measuring normalization was developed and used in scoring individual services according to the special features of those services. A total of seven service areas were scored: Residential, Social, Medical, Recreational, Educational, Psychological and Vocational. The needs of subjects were identified from institutional records and scored. Five service characteristics were further examined for normalization. These were the nature, type, name, location and degree of integration. An integrated framework for policy analysis as well as empirical results were then used to analyse findings. The study showed that community services were essentially deviant in orientation; that level of normalization were about the same for each five year period of study; that services were inadequate in meeting needs; that there was lack of coordination in delivery of services] and that "normalization" was a principle rather than a policy of the Provincial Government. Implications for policy development as well as areas for further research have been suggested.

description: An extended use of renewable energies and a trend towards increasing energy consumption lead to challenges such as temporal and spatial decoupling of energy generation and consumption. This work evaluates the possible applications and advantages of hybrid energy storage systems compared to conventional, single energy storage applications. In a mathematical approach, evaluation criteria such as frequency, probability of power transients, as well as absolute power peaks are combined to identify suitable thresholds for energy management systems on a multi-timescale basis. With experimental load profiles from a municipal application, an airport, and an industrial application, four categories, clustering similar roles of the VRFB and the SC, are developed.

description: The real-time dynamics of interacting electrons out of equilibrium contains detailed microscopic information about electronically correlated materials, which can be read out with time-resolved optical spectroscopy. The reflectivity that is typically measured in pump-probe experiments is related to the nonequilibrium optical conductivity. We show how to express this quantity in terms of real-time Green functions using dynamical mean-field theory. As an application we study the electrical response of the Falicov-Kimball model during the ultrafast buildup of the gapped phase at large interaction.

description: Astronomers have yet to establish whether high-mass protostars form from high-mass prestellar cores, similar to their lower-mass counterparts, or from lower-mass fragments at the heart of a pre-protostellar cluster undergoing large-scale collapse. Part of the uncertainty is due to a shortage of envelope structure data on protostars of a few tens of solar masses, where we expect to see a transition from intermediate-mass star formation to the high-mass process. We sought to derive the masses, luminosities, and envelope density profiles for eight sources in Cygnus-X, whose mass estimates in the literature placed them in the sampling gap. Combining these sources with similarly evolved sources in the literature enabled us to perform a meta-analysis of protostellar envelope parameters over six decades in source luminosity. We performed spectral energy distribution (SED) fitting on archival broadband photometric continuum data from 1.2 to 850 $μ$m, to derive bolometric luminosities for our eight sources plus initial mass and radius estimates for modelling density and temperature profiles with the radiative transfer package Transphere. The envelope masses, densities at 1000 AU, outer envelope radii, and density power law indices as functions of bolometric luminosity all follow established trends in the literature spanning six decades in luminosity. Most of our sources occupy an intermediate to moderately high range of masses and luminosities, which helps to more firmly establish the continuity between low- and high-mass star formation mechanisms. Our density power law indices are consistent with observed values in literature, which show no discernible trends with luminosity. Finally, we show that the trends in all of the envelope parameters for high-mass protostars are statistically indistinguishable from trends in the same variables for low- and intermediate-mass protostars.

description: Lorentz invariant violation (LIV) test is very important to study in the new physics. All the known astrophysical constraints either have a very small examinable parameter space, or are only suitable for some special theoretical models. Here we suggest that it is possible to detect the time-delay of ultra-high-energy cosmic-rays (UHECRs) directly. We discuss some difficulties in our method, including the intergalactic magnetic fields. It seems that none of them are crucial, hence this method could give a larger examinable parameter space and a stronger constraint on LIV.

description: In this paper we address the issue of universal or robust communication over quantum channels. Specifically, we consider memoryless communication scenario with channel uncertainty which is an analog of compound channel in classical information theory. We determine the quantum capacity of finite compound channels and arbitrary compound channels with informed decoder. Our approach in the finite case is based on the observation that perfect channel knowledge at the decoder does not increase the capacity of finite quantum compound channels. As a consequence we obtain coding theorem for finite quantum averaged channels, the simplest class of channels with long-term memory. The extension of these results to quantum compound channels with uninformed encoder and decoder, and infinitely many constituents remains an open problem.

description: Recent studies have shown that lung cancer screening using annual low-dose computed tomography (CT) reduces lung cancer mortality by 20% compared to traditional chest radiography. Therefore, CT lung screening has started to be used widely all across the world. However, analyzing these images is a serious burden for radiologists. The number of slices in a CT scan can be up to 600. Therefore, computer-aided-detection (CAD) systems are very important for faster and more accurate assessment of the data. In this study, we proposed a framework that analyzes CT lung screenings using convolutional neural networks (CNNs) to reduce false positives. We trained our model with different volume sizes and showed that volume size plays a critical role in the performance of the system. We also used different fusions in order to show their power and effect on the overall accuracy. 3D CNNs were preferred over 2D CNNs because 2D convolutional operations applied to 3D data could result in information loss. The proposed framework has been tested on the dataset provided by the LUNA16 Challenge and resulted in a sensitivity of 0.831 at 1 false positive per scan.

description: Exact analytical formulas are derived, by means of Keldysh Green functions, for currents and current correlation functions in a Cooper pair splitter modelled on a double quantum dot system coherently coupled to a superconductor and two normal metallic electrodes. Confining to the subspace with the inter-dot singlet we show perfect entanglement of split electrons in two separated crossed Andreev reflection processes. The studies are focused on the noise power spectrum in a whole bias voltage range. In particular, in the large voltage limit shot noise dominates and its spectrum exhibits two extraordinary side dips related to resonant inter-level current correlations caused by coherent electron-hole recombination processes accompanied by emission and absorption of photons. In the linear response limit we derived the frequency dependent admittance which shows different interference patterns for the cross and the auto current correlations.

O uso da multimodalidade como estratégia metadiscursiva em texto literário no Wattpad

Publisher: name: Labfront/UEMG
Year: 2023

description: Ao longo de uma interação, realizamos diversas manobras discursivas para garantir que ela ocorra da maneira mais efetiva possível. Nesse sentido, partimos da hipótese de que autores que publicam na plataforma Wattpad utilizam elementos multimodais como recursos interacionais. Esses recursos podem ser compreendidos como elementos metadiscursivos, pois o metadiscurso é entendido como quando enunciados se dobram sobre outros enunciados (JUBRAN, 1999). Ao valer-se de imagens para complementar a descrição de uma personagem, por exemplo, os autores do Wattpad realizam um encapsulamento metadiscursivo (KOCH, 2017) como estratégia discursiva, visando a proteção de suas faces (GOFFMAN, 2011). Ao usar uma imagem para compor sua narrativa multimodal, os autores buscam garantir que a interação com o leitor ocorra de forma efetiva — pois, além da descrição física realizada no texto, há o apoio da imagem para compor a totalidade descritiva da personagem. Assim, a pesquisa buscou demonstrar a relação entre multimodalidade, metadiscurso e negociação de faces em uma produção literária no Wattpad.

description: Predicting the effects of future global changes on species requires a better understanding of the ecological niche dynamics in response to climate; the large climatic fluctuations of the last 50,000 years can be used as a natural experiment to that aim. Here we test whether the realized niche of horse, aurochs, red deer, and wild boar changed between 47,000 and 7,500 years ago using paleoecological modelling over an extensive archaeological database. We show that they all changed their niche, with species-specific responses to climate fluctuations. We also suggest that they survived the climatic turnovers thanks to their flexibility and by expanding their niche in response to the extinction of competitors and predators. Irrespective of the mechanism behind such processes, the fact that species with long generation times can change their niche over thousands of years cautions against assuming it to stay constant both when reconstructing the past and predicting the future.

description: Observations of galactic nuclei help us to test General Relativity. Whereas the No-hair Theorem states that classical, isolated black holes eventually settle to a stationary state that can be characterized by a small number of parameters, cosmic black holes are neither isolated nor steady. Instead, they interact with the environment and evolve on vastly different time-scales. Therefore, the astrophysically realistic models require more parameters, and their values likely change in time. New techniques are needed in order to allow us to obtain independent constraints on these additional parameters. In this context, non-electromagnetic messengers have emerged and a variety of novel electromagnetic observations is going to supplement traditional techniques in the near future. In this outline, we summarize several fruitful aspects of electromagnetic signatures from accretion disks in strong-gravity regime in the outlook of upcoming satellite missions and ground-based telescopes. As an interesting example, we mention a purely geometrical effect of polarization angle changes upon light propagation, which occurs near the black hole event horizon. Despite that only numerical simulations can capture the accretion process in a realistic manner, simplified toy-models and semi-analytical estimates are useful to understand complicated effects of strong gravity near the event horizon of a rotating black hole, and especially within the plunging region below the innermost stable circular orbit.

The biosynthesis of sphingomyelin and the role of phosphatidylcholine as its precursor in baby hamster kidney-21F cells
Creators: name: Ruff, Blair A.
Publisher: name: University of British Columbia
Year: 2010

description: The last step in sphingomyelin's de novo biosyn-thetic pathway was investigated in Baby Hamster Kidney (BHK-21F) cells in tissue culture. Three types of pulse-chase experiments were done to try to identify the precursor for sphingomyelin's phosphocholine moiety. First, [Me- ³H]-choline was used to monitor the movement of the choline moiety in all the possible phosphocholine donors: ie. phosphocholine, CDP-choline, phosphatidylcholine, lysophospha-tidylcholine, and glycerophosphocholine. Radioactivity was observed in phosphocholine before appearing in phosphatidylcholine, glycerophosphocholine, and sphingomyelin. Specific radioactivities of phosphatidylcholine and sphingomyelin revealed a peculiar pattern, if representative of a precursor-product relationship between these two phospholipids. Their specific radioactivities became equal at 22 hours of chase and remained quite similar for the next 24 hours. The other two types of pulse-chase experiments both utilized prelabeled BHK phosphatidyl[Me- ³H]choline in phospholipid vesicles as their 'pulse' source. Phospholipid Exchange Protein(PLEP)-mediated exchange and polyethylene glycol/phytohemagglutinin (PEG/PHA)-mediated fusion between phospholipid vesicles and BHK cells were used to introduce the labeled phosphatidylcholine. In addition, in the 'fusion' experiments, other labeled compounds (glycerophosphocholine and sphingomyelin) were substituted for labeled phosphatidylcholine. PLEP- mediated exchange of labeled phosphatidylcholine did not result in enough transfer of radioactivity into the cell to adequately monitor individual cell phospholipids or any transfer of label - ie. from phosphatidylcholine to sphingomyelin. However, PEG/PHA-mediated fusion of vesicles and cells did result in enough radioactivity showing up in the cells. When labeled phosphatidylcholine was used, the radioactivity ratio between it and sphingomyelin averaged around 16, depending on the length of the chase (2-52 hours)m The use of either labeled glycerophosphocholine or sphingomyelin resulted in a ratio of about 1.8. One 'cold-trap1 experiment was done by including a large amount of unlabeled glycerophosphocholine with labeled phosphatidylcholine in the vesicle preparation. The resultant radioactivity in sphingomyelin was 50% less than previously, but phosphatidylcholine's had remained the same. The evidence seems to indicate a reversible precursor-product relationship between phosphatidylcholine and sphingomyelin, but does not clearly show whether or not any other intermediate (such as glycerophosphocholine) is also involved.

description: We study the symmetry classes of graphene quantum dots, both open and closed, through the conductance and energy level statistics. For abrupt termination of the lattice, these properties are well described by the standard orthogonal and unitary ensembles. However, for smooth mass confinement, special time-reversal symmetries associated with the sublattice and valley degrees of freedom are critical: they lead to block diagonal Hamiltonians and scattering matrices with blocks belonging to the unitary symmetry class even at zero magnetic field. While the effect of this structure is clearly seen in the conductance of open dots, it is suppressed in the spectral statistics of closed dots, because the intervalley scattering time is shorter than the time required to resolve a level spacing in the closed systems but longer than the escape time of the open systems.

description: Neutron diffraction has been used to determine the magnetic structure of Na$_8$Cu$_5$O$_{10}$, a stoichiometric compound containing chains based on edge-sharing CuO$_4$ plaquettes. The chains are doped with 2/5 hole per Cu site and exhibit long-range commensurate charge order with an onset well above room temperature. Below $T_N = 23$ K, the neutron data indicate long-range collinear magnetic order with a spin density modulation whose propagation vector is commensurate along and incommensurate perpendicular to the chains. Competing interchain exchange interactions are discussed as a possible origin of the incommensurate magnetic order.

description: Energy system models for long-term planning are widely used to explore the future electricity system. Typically, to represent the future electricity demand in these models, historical demand profiles are used directly or scaled up linearly. Although the volume change for the electricity demand is considered, the potential change of the demand pattern is ignored. Meanwhile, the future electricity demand pattern is highly uncertain due to various factors, including climate change, e-mobility, electric heating, and electric cooling. We use a techno-economic cost optimization model to investigate a stylized case and assess the effects on system cost and electricity supply mix of assuming different demand patterns for the models. Our results show that differences in diurnal demand patterns affect the system cost by less than 3%. Similarly, demand profiles with a flat seasonal variation or a winter peak result in only minor changes in system cost, as compared to the present demand profile. Demand profiles with a summer peak may display a system cost increase of up to 8%, whereas the electricity supply mix may differ by a factor of two. A more detailed case study is conducted for Europe and the results are consistent with the findings from the stylized case.

description: Enforcing balance of multi-limbed robots in multiple non-coplanar unilateral contact settings is challenging when a subset of such contacts are also induced in motion tasks. The first contribution of this paper is in enhancing the computational performance of state-of-the-art geometric center-of-mass inclusion-based balance method to be integrated online as part of a task-space whole-body control framework. As a consequence, our second contribution lies in integrating such a balance region with relevant contact force distribution without pre-computing a target center-of-mass. This last feature is essential to leave the latter with freedom to better comply with other existing tasks that are not captured in classical twolevel approaches. We assess the performance of our proposed method through experiments using the HRP-4 humanoid robot.

description: We consider nonparametric estimation of mean regression and conditional variance (or volatility) functions in nonlinear stochastic regression models. Simultaneous confidence bands are constructed and the coverage probabilities are shown to be asymptotically correct. The imposed dependence structure allows applications in many linear and nonlinear auto-regressive processes. The results are applied to the S&P 500 Index data.

description: Recently, scanning tunneling microscopy on Bi-2212 cuprate superconductor has revealed a spatial variation of the energy gap that is directly correlated with a modulation of the apical oxygen position. We identify two mechanisms by which out-of-plane oxygens can modulate the pairing interaction within the CuO_2 layer: a covalency between the x^2-y^2 band and apical p-orbital, and a screening of correlation U by apical oxygen polarization. Both effects strongly depend on the apical oxygen position and their cooperative action explains the experiment.

description: Fan and Li propose a family of variable selection methods via penalized likelihood using concave penalty functions. The nonconcave penalized likelihood estimators enjoy the oracle properties, but maximizing the penalized likelihood function is computationally challenging, because the objective function is nondifferentiable and nonconcave. In this article, we propose a new unified algorithm based on the local linear approximation (LLA) for maximizing the penalized likelihood for a broad class of concave penalty functions. Convergence and other theoretical properties of the LLA algorithm are established. A distinguished feature of the LLA algorithm is that at each LLA step, the LLA estimator can naturally adopt a sparse representation. Thus, we suggest using the one-step LLA estimator from the LLA algorithm as the final estimates. Statistically, we show that if the regularization parameter is appropriately chosen, the one-step LLA estimates enjoy the oracle properties with good initial estimators. Computationally, the one-step LLA estimation methods dramatically reduce the computational cost in maximizing the nonconcave penalized likelihood. We conduct some Monte Carlo simulation to assess the finite sample performance of the one-step sparse estimation methods. The results are very encouraging.

Distribution and variability of some chemical parameters in the soils of a forested hillslope

Publisher: name: University of British Columbia

description: Trends in soil chemistry are studied on a 300 meter long hillslope in the Cascade Mountain Range of southwestern British Columbia. Although trends are not wholly consistent from horizon to horizon, the following general statements can be made: pH tends to increase downslope; exchangeable calcium, exchangeable magnesium and cation exchange capacity decrease noticeably downslope; carbon may decrease slightly downslope; nitrogen, carbon/nitrogen ratio, percent base saturation, exchangeable sodium and exchangeable potassium remain effectively constant downslope. Soil chemistry is shown to be related to horizon, slope position and parent material. Variability among chemical species increases in the sequence: pH, percent base saturation, carbon/nitrogen ratio, cation exchange capacity, nitrogen, exchangeable calcium, percent carbon, exchangeable potassium, exchangeable sodium, exchangeable magnesium. Variability fluctuates among soil horizons but not so noticeably with slope position. A slight increase in variability with the size of the area sampled is evident.

description: The new rare-earth arsenate superconductors are layered, low carrier density compounds with many similarities to the high-Tc cuprates. An important question is whether they also exhibit weak-coupling across randomly oriented grain-boundaries. In this work we show considerable evidence for such weak-coupling by study of the dependence of magnetization in bulk and powdered samples. Bulk sample magnetization curves show very little hysteresis while remanent magnetization shows almost no sample size dependence, even after powdering. We conclude that these samples exhibit substantial electromagnetic granularity on a scale approximating the grain size, though we cannot yet determine whether this is intrinsic or extrinsic.
