The impacts of hydro-dams on forestry in southeastern British Columbia
Creators: name: Szaraz, Gerard
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study is to provide a description of the repercussions of hydro-dam development upon forestry in southeastern British Columbia. This study develops a systems viewpoint, where selected indicators - timber supply, access and transportation, forest land value, and reservoir clearing - are examined to help place land allocation decisions within a comprehensive framework. First, a timber supply model is developed, in which forest land withdrawal to hydro-dams is scrutinized. The model is then expanded to account for timber supply and demand relationships. Findings reveal that approximately 50,000 hectares of better than average sites were withdrawn from forest land, accounting for a reduction in timber supply of approximately 180,000 cubic meters annually. Second, changes in accessibility and transportation patterns due to hydro-dam projects are identified in terms of timber supply disruption, and strategies followed to re-establish forestry. Mica and Revelstoke dams are examined to show the importance of allocating economic resources to forestry for the maintenance of the activity. Third, forest land is evaluated in following the four methodological steps: (1) outline of a benefit-cost analysis framework, (2) definition of a general approach to evaluation, (3) description of B.C. Hydro's assessment, and (4) recommendations for improvement. The case of the Revelstoke Dam is examined, and it is concluded that resource development scenarios must take into consideration timber supply and demand factors. Fourth, reservoir clearing is described to outline an important aspect of short-term impact, and to express the way by which the Forest Service, B.C. Hydro and forest companies co-ordinated their efforts during this transition phase. The study concludes by suggesting that the impacts may be alleviated by initiating intensive forest management in areas affected by hydro-dam projects. The design of an effective system of timber allocation may also permit maintenance, and possible improvement, of accessibility and transportation patterns. However, the success of these actions depends upon the availability of sufficient funding. Finally, within a broader perspective, it is recommended that integrated resource management, as a control mechanism for land allocation and management, be adopted.

description: The outstanding multidisciplinary applicability of nanomaterials has paved the path for the rapid advancement of nanoscience during the last few decades. Such technological progress subsequently results in an inevitable environmental exposure of nanomaterials. Presently, nanomaterials are employed in an extensive range of commercial products. Safe and sustainable incorporation of nanomaterials in industrial products requires a profound and comprehensive understanding of their potential toxicity. Among different nanomaterials, carbon nanomaterials marked its notable superiority toward the development of state-of-the-art nanotechnology due to the significant contribution of each of the carbon allotropes with varied dimensionality. The zero-dimensional fullerene, one-dimensional carbon nanotube, and two-dimensional graphene possess an exclusive combination of distinctive properties that are utilized in most of the nanotechnology-based products nowadays. However, potential risk factors are associated with the production and the use of carbon nanomaterials. Consequently, the number of studies regarding the assessment of the toxicity of these nanomaterials has increased rapidly in the past decade. This chapter will summarize the recent scientific efforts on the toxicity evaluation of different carbon nanomaterials.

description: Memantine is used to prevent glutamate-mediated excitotoxicity and neurodegeneration in Alzheimer’s disease. As glutamine is one of the major source of anabolism in fast growing cancer cells, we aimed to interfere with the cancer cell metabolism in A549 lung cancer cells by using memantine. The effects of memantine on cell cycle progression and cell death in A549 cells were assessed by MTT assay and PI staining. Cells were treated with 0.25 mM memantine for 48 hours and then cell metabolism (AMPKA1, AMPKA2, HIF1A, B-catenin, PKM), apoptosis (p53, p21, Bax, Bcl-XL, NOXA, PUMA) and autophagy related (LC3B-I, LC3B-II, SQSTM1) mRNA and protein expressions were investigated by RT-qPCR and western blotting. Memantine decreased cell viability significantly in a concentration-dependent manner by inducing G0/G1 cell cycle arrest. Our results suggest that memantine activates AMPK1/2 significantly (p=0.039 and p=0.0105) that led cells through apoptosis and autophagy by decreasing cancer cell metabolism regulators like HIF1A, B-catenin and PKM as the consequence of this energetic shift. Memantine represents a useful tool to target metabolism in cancer cells. Therefore, it might be used a new repurposed drug in cancer treatment.

Using a strong-disorder energy-space renormalization group, it is shown that for any amount of disorder the critical behavior is controlled by an infinite-randomness fixed point in the universality class of the random transverse-field Ising models. The experimental relevance of our results are discussed.

Capacity Analysis can be an essential tool for modernizing our grid and finally unlocking the value of distribution grid capacity. This class will provide updates on many recent utility planning policies for publishing Integration or Hosting Capacity Analysis. Capacity analysis also becomes an important dataset in evaluating Non-Wires Alternatives. Data can be used to tackle big picture challenges and location specific needs of the grid. In addition, the rapid electrification of transport depends on the utilities' ability to forecast capacity and meet the demand under ever-changing mix of generation resources. This is why the concepts of capacity analysis should be promoted and developed to achieve a stronger, smarter, and greener electric grid.

description: Dim radio-quiet neutron star (DRQNS) 1E 1207.4-5209 is one of the most heavily examined isolated neutron stars. Wide absorption lines were observed in its spectrum obtained by both XMM-Newton and Chandra X-ray satellites. These absorption lines can be interpreted as a principal frequency centered at 0.7 keV and its harmonics at 1.4, 2.1 and possibly 2.8 keV. The principal line can be formed by resonant proton cyclotron scattering leading to a magnetic field which is two orders of magnitude larger than the perpendicular component of the surface dipole magnetic field (B) found from the rotation period (P) and the time rate of change in the rotation period (P) of 1E 1207.4-5209. Besides, age of the supernova remnant (SNR) G296.5+10.0 which is physically connected to 1E 1207.4-5209 is two orders of magnitude smaller than the characteristic age ($τ$=P/2P) of the neutron star. These huge differences between the magnetic field values and the ages can be explained based on a B-decay model. If the decay is assumed to be exponential, the characteristic decay time turns out to be several thousand years which is three orders of magnitude smaller than the characteristic decay time of radio pulsars represented in an earlier work. The lack of detection of radio emission from DRQNSs and the lack of point sources and pulsar wind nebulae in most of the observed SNRs can also be partly explained by such a very rapid exponential decay. The large difference between the characteristic decay times of DRQNSs and radio pulsars must be related to the differences in the magnetic fields, equation of states and masses of these isolated neutron stars.

Phospholipids as adjuncts for chromaffin granule release
Creators: name: Nayar, Rajiv
Publisher: name: University of British Columbia
Year: 2010

description: The chromaffin granules of adrenal medulla cells are membrane bound entities which act as storage vesicles for catecholamines, ATP, and protein. Release of contents to the extracellular medium appears to occur via calcium-stimulated exocytosis which involves fusion with the plasma membrane. The molecular mechanism of exocytosis was approached from two points of view. First, it was shown by ³¹P-NMR techniques that the endogenous phospholipids assume a liquid-crystalline configuration at physiological temperature both in the intact membrane and in model systems composed of the extracted lipid. This is consistent with a structural role of phospholipids in vivo, serving to maintain membrane integrity. Addition of calcium to these systems resulted in little change in the biological membrane spectra and in the appearance of a relatively small component (<10 %) , possibly arising from phospholipid in the hexagonal H₁₁ phase in the model systems composed of the isolated total lipids. Second, incubation of intact granules in the presence of upto 10 mM calcium did not cause significant release of contents. Similarily, incubation in the presence of exogenous lipid vesicles alone did not induce release. However, incubation with phospholipid systems, which have the ability to undergo structural transitions in the presence of calcium, followed by the introduction of calcium caused immediate and total release of granule contents. This behaviour is attributed to disruption of membrane integrity arising from calcium induced fusion of the phospholipid vesicles with the granules. In contrast, incubation with phospholipid systems which do not undergo structural transitions in the presence of calcium is quite ineffective. On the basis of this information, a mechanism of calcium-induced exocytotic release of catecholamines in vivo is proposed.

description: We study the asymptotic properties of the SCAD-penalized least squares estimator in sparse, high-dimensional, linear regression models when the number of covariates may increase with the sample size. We are particularly interested in the use of this estimator for simultaneous variable selection and estimation. We show that under appropriate conditions, the SCAD-penalized least squares estimator is consistent for variable selection and that the estimators of nonzero coefficients have the same asymptotic distribution as they would have if the zero coefficients were known in advance. Simulation studies indicate that this estimator performs well in terms of variable selection and estimation.

description: The contribution of the fundamental gap E_ as well as those of the E_ + Delta(so) and E+ transitions to the dielectric function of GaAs1-xNx alloys near the band edge were determined from variable-angle spectroscopic ellipsometry and modulated photoreflectance spectroscopy analyses. The oscillator strength of the E_ optical transition increases weakly with nitrogen incorporation. The two experimental techniques independently reveal that not only the oscillator strength of the E+ transition but also that of E_ + Delta(so) become larger compared to that of the fundamental gap as the N content increases. Since the same conduction band is involved in both the E_ transition and its split-off replica, these results reveal that adding nitrogen in GaAs1-xNx alloys affects not only the conduction but also the valence bands.

description: We study the response of the QCD vacuum to an external magnetic field, in the presence of strong CP violation. Using chiral perturbation theory and large N_c expansion, we show that the external field would polarize quantum fluctuations and induce an electric dipole moment of the vacuum, along the direction of the magnetic field. We estimate the magnitude of this effect in different physical scenarios. In particular, we find that the polarization induced by the magnetic field of a magnetar could accelerate electric charges up to energies of the order θ10^3 TeV. We also suggest a connection with the possible existence of "hot-spots" on the surface of neutron stars.

description: Vacancy-induced magnetism in graphene bilayers is investigated using spin-polarized density functional theory calculations. One of two graphene layers has a monovacancy. Two atomic configurations for bilayers are considered with respect to the position of the monovacancy. We find that spin magnetic moments localized at the vacancy site decreases by ~10 % for our two configurations, compared with the graphene monolayer with a monovacancy. The reduction of the spin magnetic moment in the graphene bilayers is attributed to the interlayer charge transfer from the adjacent layer to the layer with the monovacancy, compensating for spin magnetic moments originating from quasilocalized defect state.

description: KS 1741-293, discovered in 1989 by the X-ray camera TTM in the Kvant module of the Mir space station and identified as an X-ray burster, has not been detected in the hard X band until the advent of the INTEGRAL observatory. Moreover this source has been recently object of scientific discussion, being also associated to a nearby extended radio source that in principle could be the supernova remnant produced by the accretion induced collapse in the binary system. Our long term monitoring with INTEGRAL, covering the period from February 2003 to May 2005, confirms that KS 1741-293 is transient in soft and hard X band. When the source is active, from a simultaneous JEM-X and IBIS data analysis, we provide a wide band spectrum from 5 to 100 keV, that can be fit by a two component model, a multiple blackbody for the soft emission and a Comptonized or a cut-off power law model for the hard component. Finally, by the detection of two X-ray bursters with JEM-X, we confirm the bursting nature of KS 1741-293, including this source in the class of the hard tailed X-ray bursters.

description: Instrumental projects that will improve the direct optical finding and characterisation of exoplanets have advanced sufficiently to trigger organized investigation and development of corresponding signal processing algorithms. The first step is the availability of field-of-view (FOV) models. These can then be submitted to various instrumental models, which in turn produce simulated data, enabling the testing of processing algorithms. We aim to set the specifications of a physical model for typical FOVs of these instruments. The dynamic in resolution and flux between the various sources present in such a FOV imposes a multiscale, independent layer approach. From review of current literature and through extrapolations from currently available data and models, we derive the features of each source-type in the field of view likely to pass the instrumental filter at exo-Earth level. Stellar limb darkening is shown to cause bias in leakage calibration if unaccounted for. Occurrence of perturbing background stars or galaxies in the typical FOV is unlikely. We extract galactic interstellar medium background emissions for current target lists. Galactic background can be considered uniform over the FOV, and it should show no significant drift with parallax. Our model specifications have been embedded into a Java simulator, soon to be made open-source. We have also designed an associated FITS input/output format standard that we present here.

Augmented GARCH sequences: Dependence structure and asymptotics

Publisher: name: arXiv
Year: 2008
Subjects: subject: Statistics Theory (math.ST)

description: The augmented GARCH model is a unification of numerous extensions of the popular and widely used ARCH process. It was introduced by Duan and besides ordinary (linear) GARCH processes, it contains exponential GARCH, power GARCH, threshold GARCH, asymmetric GARCH, etc. In this paper, we study the probabilistic structure of augmented $\mathrm {GARCH}(1,1)$ sequences and the asymptotic distribution of various functionals of the process occurring in problems of statistical inference. Instead of using the Markov structure of the model and implied mixing properties, we utilize independence properties of perturbed GARCH sequences to directly reduce their asymptotic behavior to the case of independent random variables. This method applies for a very large class of functionals and eliminates the fairly restrictive moment and smoothness conditions assumed in the earlier theory. In particular, we derive functional CLTs for powers of the augmented GARCH variables, derive the error rate in the CLT and obtain asymptotic results for their empirical processes under nearly optimal conditions.

Furthermore we show that the computed two dimensional Angular Correlation of Electron Positron Annihilation Radiation (the so called $2D$-ACAR) clearly demonstrates the existence of these $L$-hole pockets, which remains robust against electronic correlations. A $2D$-ACAR experiment should therefore provide the "smoking-gun" proof for the existence of the $L$-hole pockets in the palladium Fermi surface.

description: We present a study of the extinction, traced by the Balmer decrement, in HII regions in the dwarf galaxies NGC 1569 and NGC 4214. We find that the large-scale extinction around the most prominent HII regions in both galaxies forms a shell in which locally the intrinsic extinction can adopt relatively high values ($A_V = 0.8 - 0.9$ mag) despite the low metallicity and thus the low overall dust content. The small-scale extinction (spatial resolution $\sim$0.3'') shows fluctuations that are most likely due to variations in the dust distribution. We compare the distribution of the extinction to that of the dust emission, traced by Spitzer emission at 8 and 24 \mi, and to the emission of cold dust at 850 \mi. We find in general a good agreement between all tracers, expect for the 850 \mi emission in NGC 4214 which is more extended than the extinction and the other emissions. Whereas in NGC 1569 the dust emission at all wavelengths is very similar, NGC 4214 shows spatial variations in the 24-to-850 \mi ratio. We furthermore compared the 24 \mi and the extinction-corrected Halpha emission from HII regions in a sample of galaxies with a wide range of metallicities and found a good correlation between both emissions, independent of metallicity. We suggest that this lack of dependence on metallicity might be due to the formation of dust shells with a relatively constant opacity, like the ones observed here, around ionizing stars.

description: In high transition temperature (T_c) superconductivity, charge doping is a natural tuning parameter that takes copper oxides from the antiferromagnet to the superconducting region. In the metallic state above T_c the standard Landau's Fermi-liquid theory of metals as typified by the temperature squared (T^2) dependence of resistivity appears to break down. Whether the origin of the non-Fermi-liquid behavior is related to physics specific to the cuprates is a fundamental question still under debate. We uncover a new transformation from the non-Fermi- to a standard Fermi-liquid state driven not by doping but by magnetic field in the overdoped high-T_c superconductor Tl_2Ba_2CuO_{6+x}. From the c-axis resistivity measured up to 45 T, we show that the Fermi-liquid features appear above a sufficiently high field which decreases linearly with temperature and lands at a quantum critical point near the superconductivity's upper critical field -- with the Fermi-liquid coefficient of the T^2 dependence showing a power-law diverging behavior on the approach to the critical point. This field-induced quantum criticality bears a striking resemblance to that in quasi-two dimensional heavy-Fermion superconductors, suggesting a common underlying spin-related physics in these superconductors with strong electron correlations.

description: Low energy scattering amplitudes for two atoms in one- and two-dimensional atomic wave guides are derived for short range isotropic and resonant interactions in high partial wave channels. Taking into account the finite width of the resonance which was neglected in previous works is shown to have important implications in the properties of the confinement induced resonances. For spin polarized fermions in quasi-1D wave guides it imposes a strong constraint on the atomic density for achieving the Fermi Tonks Girardeau gas. For a planar wave guide, the charateristics of the 2D induced scattering resonances in $p$- and d-wave are determined as a function of the 3D scattering parameters and of the wave guide frequency.
Laying the Groundwork for Creating Utility Analytics (Slides)

Utility analytics do not start with buying an analytic package and hiring a data scientist or two. Instead, they start in the field with the decisions on what data to capture, how much of it is transmitted, where it is processed and storage. Relays and other sensing equipment in the field have many inputs, and some are only connected to a few of these inputs, meaning data is not possible to capture, should those inputs be connected? How do you create a simple diagram that allows the discussion of the inputs and their value? Why are field walk downs needed and what can I do about fixing my topology in my systems – which is the basic requirement for most analytics?
Once the right field data is flowing into the enterprise, what do I do with it, and why can’t I just drop it into an analytics package or an AI system and be done with it? What do you mean there is hard work between raw data and actionable analytics? What are the hard won lessons of real insight?

description: Despite decades of research, the structural basis for the optical properties of chromophoric dissolved organic matter (CDOM) and humic substances (HS) are still not clear. Through several analytical techniques, it is known that CDOM contains carbonyls (aromatic ketones, aldehydes, and quinones), carboxylic acids, and phenols. The charge-transfer model proposed to explain the optical properties of these materials assigns the short-wavelength absorption (<350 nm) and fluorescence emission to electron donors (phenols) and acceptors (carbonyls), while the long-wavelength absorption is attributed to charge-transfer interactions among these species. Because carbonyls are reducible species a method was developed to eliminate them and to investigate its effects on the optical properties of HS in relation to their structure. In addition, the effect of pH on the optical absorption spectra for both untreated and borohydride reduced HS was examined and related to the deprotonation of carboxylic acids and phenolic moieties.

description: This review paper highlights the recent developments in supercapacitors by pointing out the significance of appropriate electrode and device designs. We reported ten extremely high-performance supercapacitors with specific capacitance values among the highest available until now to the best of our knowledge. These state-of-the-art designs employing innovative electrode materials have been discussed along with their short descriptions. The supercapacitors collected here possess the most promising potential for facilitating next-generation systems in energy harvesting and storage. This review is just the surface that can help provide a pathway for supercapacitor research, which is still wide open for exploring and developing new advanced materials for energy applications of the future.

BACKGROUND: In South Africa, cervical cancer remains among the most common cancers and a leading cause of cancer death. Co-infection with HIV increases the risk of developing cervical pre-cancer and cancer. We analysed National Health Laboratory Service cervical cytology data to investigate geographic variations of Pap smear coverage, quality, and high grade lesions. METHODS: Facility-level data were extracted from the NHLS for April 2013-March 2014. We present results and choropleth maps detailing coverage, adequacy and high-grade Pap smear cytology abnormalities defined as Pap smears suspicious for invasive carcinoma, high-grade squamous intraepithelial lesions (HSIL) or atypical squamous cells: cannot exclude HSIL (ASC-H). RESULTS: 4,562 facilities submitted 791,067 cytology slides. The interquartile range (IQR) for Pap smear coverage among HIV-infected women was 26-41%; similar to coverage in women aged 30 and older (IQR: 26-42%). 6/52 districts had adequacy rates above the national standard (70%) and 2/52 districts had adequacy rates below 35%. We observed marked variation in Pap smear abnormalities across the country, with the proportion of high-grade cytology abnormalities ≥0.3% in 17/52 districts. CONCLUSION: Using district-level choropleth maps, we are able to display variations in Pap smear coverage, quality, and results across South Africa. This approach may be used to improve resource allocation, achieving better equity in cervical cancer prevention.
Open Access in der Max-Planck-Gesellschaft – Determinanten, Strategien und Perspektiven der Umsetzung in ausgewählten Institutsbibliotheken

description: Die Arbeit beschäftigt sich mit der Umsetzung von Open Access und ihrer Determinanten in einer der vier großen deutschen außeruniversitären Forschungsorganisationen – der Max-Planck-Gesellschaft (MPG). Es wird dafür untersucht, welche Open-Access-bezogenen Services an Bibliotheken ausgewählter Max-Planck-Institute konkret angeboten werden und geplant sind sowie welche Faktoren bei der lokalen Umsetzung von Open Access befördernd wirken, welche Bedarfe existieren und welche Potentiale sich für die Bibliotheken daraus ergeben. Zudem wird eruiert, welche Faktoren die Arbeit der Institutsbibliotheken dabei beeinflussen und welche Handlungsspielräume sich hierbei ergeben. Die Analyse wird durch die Betrachtung der übergeordneten Open-Access-Strategie der MPG und der Aufgabenverteilung innerhalb ihrer Informationsversorgungsstruktur in einen größeren Kontext eingebettet. Dazu wurden leitfadengestützte ExpertInneninterviews mit zehn VertreterInnen von Max-Planck-Institutsbibliotheken geführt, in denen Informationen und Einschätzungen zu den genannten Themenkomplexen abgefragt wurden. Die konkrete Umsetzung von Open Access erfolgt in den befragten Bibliotheken auf unterschiedliche, stark an die lokalen Bedingungen und individuellen Bedürfnisse der Zielgruppe angepasste Weise. Dabei wird diese Arbeit, neben weiteren Faktoren, stark durch das persönlichkeitszentrierte Funktionsprinzip der MPG und die Publikationskulturen der jeweiligen Fachdisziplinen beeinflusst. Trotz identifizierter Bedarfe zeigt sich, dass die MPG ihrer selbstgesetzten Aufgabe, eine starke Triebkraft bei der Transformation des wissenschaftlichen Publikationssystems hin zu vollständigem Open Access zu sein, mit großen Bemühungen nachgeht. Die InformationsspezialistInnen an den Instituten spielen dabei eine essenzielle Rolle.

description: Torsional oscillator (TO) is an experimental technique which is widely used to investigate superfluid responses in helium systems confined in porous materials or adsorbed on substrates. In these systems, heat capacity (HC) is also an important quantity to study the local thermodynamic properties. We have developed a simple method to incorporate the capability of HC measurement into an existing TO without modifying the TO itself. By inserting a rigid thermal isolation support made of alumina and a weak thermal link made of fine copper wires between a standard TO and the mixing chamber of a dilution refrigerator in parallel, we were able to carry out simultaneous TO and HC measurements on exactly the same helium sample, i.e., four atomic layers of $^4$He adsorbed on graphite, with good accuracies down to 30 mK. The data reproduced very well the previous workers' results obtained independently using setups optimized for individual measurements. This method is conveniently applicable to a variety of experiments where careful comparisons between results of TO and HC measurements are crucial. We describe how to design the thermal isolation support and the weak thermal link to manage conflicting requirements in the two techniques.

Publisher: name: IEEE
Year: 2021

Capacity Analysis can be an essential tool for modernizing our grid and finally unlocking the value of distribution grid capacity. This class will provide updates on many recent utility planning policies for publishing Integration or Hosting Capacity Analysis. Capacity analysis also becomes an important dataset in evaluating Non-Wires Alternatives. Data can be used to tackle big picture challenges and location specific needs of the grid. In addition, the rapid electrification of transport depends on the utilities' ability to forecast capacity and meet the demand under ever-changing mix of generation resources. This is why the concepts of capacity analysis should be promoted and developed to achieve a stronger, smarter, and greener electric grid.
