description: We examine scale invariant Fulop-Tsutsui couplings in a quantum vertex of a general degree $n$. We demonstrate that essentially same scattering amplitudes as for the free coupling can be achieved for two $(n-1)$-parameter Fulop-Tsutsui subfamilies if $n$ is odd, and for three $(n-1)$-parameter Fulop-Tsutsui subfamilies if $n$ is even. We also work up an approximation scheme for a general Fulop-Tsutsui vertex, using only $n$ $δ$ function potentials.

description: We consider a gravitating spherically symmetric configuration consisting of a scalar field non-minimally coupled to ordinary matter in the form of a perfect fluid. For this system we find static, regular, asymptotically flat solutions for both relativistic and non-relativistic cases. It is shown that the presence of the non-minimal interaction leads to substantial changes both in the radial matter distribution of the star and in the star's total mass. A simple stability test indicates that, for the choice of parameters used in the paper, the solutions are unstable.

Condensing Nielsen-Olesen strings and the vortex-boson duality in 3+1 and higher dimensions

description: The vortex-boson (or Abelian-Higgs, XY) duality in 2+1 dimensions demonstrates that the quantum disordered superfluid is equivalent to an ordered superconductor and the other way around. Such a duality structure should be ubiquitous but in 3+1 (and higher) dimensions a precise formulation of the duality is lacking. The problem is that the topological defects become extended objects, strings in 3+1D. We argue how the condensate of such vortex strings must behave from the known physics of the disordered superfluid, namely the Bose-Mott insulator. A flaw in earlier proposals is repaired, and a more direct viewpoint, avoiding gauge fields, in terms of the physical supercurrent is laid out, that also easily generalizes to higher-dimensional and more complicated systems. Furthermore topological defects are readily identified; we demonstrate that the Bose-Mott insulator supports line defects, which may be seen in cold atom experiments.

description: We find that AdS spacetime with a non-trivial linear dilaton field is an exact solution in the effective action of string theory, which is described by gravity with the Gauss-Bonnet curvature terms coupled to a dilaton field in the string frame. The AdS radius is determined by the spacetime dimensions and the coupling constants of curvature corrections. We also construct the asymptotically AdS black hole solutions with a linear dilaton field numerically. We discuss the thermodynamical properties of those solutions. Extending the model to the case with the even-order higher Lovelock curvature terms, we also find the exact AdS spacetime with non-trivial dilaton. We further find a cosmological solution with a bounce of three space and a solitonic solution with a non-trivial dilaton field, which is regular everywhere and approaches an asymptotically AdS spacetime.

The effects of Co particle size on the deactivation of Co/Al₂O₃ and Re-Co/Al₂O₃ catalysts in the Fischer-Tropsch synthesis
Creators: name: Ghasvareh, Pooneh
Publisher: name: University of British Columbia
Year: 2017

description: To assess the effect of Co particle size on the deactivation of Co catalysts during Fischer-Tropsch (FT) synthesis, a series of Co/Al₂O₃ and Re-Co/Al₂O₃ FT catalysts with varying Co particle size, were tested in a continuous flow, stirred tank reactor operated at 220ºC, 2.1MPa and a H₂/CO = 2/1 synthesis gas for periods up to 190 h time-on-stream (TOS). At the chosen operating conditions, carbon deposition was the main cause of catalyst deactivation and the initial rate of carbon deposition per active Co site increased with increased Co particle size (dC₀=2– 22 nm) when measured at approximately the same CO conversion level. Results showed that catalyst stability was dependent upon the Co particle size, degree-of-reduction (DOR) of the catalyst precursor and the CO conversion. The initial rate of carbon deposition increased with increase in CO conversion, when CO conversion ≤ 40%, for a particular catalyst, whereas at high concentrations of H₂O and CO₂ in the reactor (CO conversions> 60%), the initial rate of carbon deposition decreased with increased CO conversion. Furthermore, Co/Al₂O₃ catalysts with small Co particles (dC₀ = 2 nm and dC₀ = 1 nm) were activated with TOS during the FT synthesis. These catalysts had a low DOR (≤3%) and were reduced further when exposed to the synthesis gas. Comparison between the extent of catalyst deactivation for the Co/Al₂O₃ and Re-Co/Al₂O₃ model catalysts and a commercial Co/P-Al₂O₃ catalyst (Co catalyst on a P modified Al₂O₃ support), showed that the Co/P-Al₂O₃ catalyst was more stable during ~160 TOS due to a reduced carbon deposition rate. However, when the catalyst was operated over a range of process conditions (i.e, temperature, pressure and H₂/CO ratio) for extended operating periods (up to 1200 h), the CH₄ selectivity increased at TOS > 400 h and when the catalyst was exposed to high temperature (T≥ 230 ºC) and a PH₂O/PH₂ ratio > 0.5. The change in CH₄ selectivity was shown to be dependent on the high 𝑃𝐻₂𝑂 in the reactor which resulted in Co oxidation and hence a change in product selectivity.
Recommendations for offline combustion-based nitrogen isotopic analysis of silicate minerals and rocks
Creators: Li, Long

Labbe, Mark
Publisher: name: University of Alberta Library
Year: 2021


Rationale

Due to isotope fractionations during partial nitrogen release from minerals and rocks, the complete extraction of nitrogen for analysis is crucial to ensure high-quality nitrogen isotopic data. However, the appropriate nitrogen extraction conditions (e.g. temperature, duration) have not been established for most silicate minerals and rocks.
Methods

Nitrogen in a number of common minerals and rocks was extracted using the most robust sealed-tube offline combustion techniques, purified and quantified in a custom-made metal manifold, and carried by helium gas to an isotope ratio mass spectrometer for isotopic measurement at nanomolar nitrogen level. Each mineral or rock was combusted in a variety of temperature and duration conditions to compare the nitrogen yields and isotopic compositions.
Results

The nitrogen yields and isotopic compositions of minerals and rocks are strongly affected by combustion temperature and duration. The optimal combustion temperature is lowest for cyclosilicate minerals, followed by phyllosilicate, tectosilicate and inosilicate minerals. Preheating of samples can induce significant nitrogen loss and δ15N shift. Heating of samples above their optimal temperatures may cause nitrogen re-assimilation by the residual mineral or rock.
Conclusions

Each mineral or rock has a characteristic optimal temperature and duration for complete nitrogen release. Preheating, under-heating or over-heating can cause nitrogen loss and isotopic shift. Therefore, we recommend using the offline combustion techniques and the optimal combustion conditions obtained in this study for nitrogen quantification and isotopic analysis of silicate minerals and rocks.

description: The Hamiltonian structure of a class of three-dimensional (3D) Lotka-Volterra (LV) equations is revisited from a novel point of view by showing that the quadratic Poisson structure underlying its integrability structure is just a real three-dimensional Poisson-Lie group. As a consequence, the Poisson coalgebra map that is given by the group multiplication provides the keystone for the explicit construction of a new family of 3N-dimensional integrable systems that, under certain constraints, contain N sets of deformed versions of the 3D LV equations. Moreover, by considering the most generic Poisson-Lie structure on this group, a new two-parametric integrable perturbation of the 3D LV system through polynomial and rational perturbation terms is explicitly found.

On the Estimation of Confidence Intervals for Binomial Population Proportions in Astronomy: The Simplicity and Superiority of the Bayesian Approach

Year: 2010

description: I present a critical review of techniques for estimating confidence intervals on binomial population proportions inferred from success counts in small-to-intermediate samples. Population proportions arise frequently as quantities of interest in astronomical research; for instance, in studies aiming to constrain the bar fraction, AGN fraction, SMBH fraction, merger fraction, or red sequence fraction from counts of galaxies exhibiting distinct morphological features or stellar populations. However, two of the most widely-used techniques for estimating binomial confidence intervals--the 'normal approximation' and the Clopper & Pearson approach--are liable to misrepresent the degree of statistical uncertainty present under sampling conditions routinely encountered in astronomical surveys, leading to an ineffective use of the experimental data (and, worse, an inefficient use of the resources expended in obtaining that data). Hence, I provide here an overview of the fundamentals of binomial statistics with two principal aims: (i) to reveal the ease with which (Bayesian) binomial confidence intervals with more satisfactory behaviour may be estimated from the quantiles of the beta distribution using modern mathematical software packages (e.g. R, matlab, mathematica, IDL, python); and (ii) to demonstrate convincingly the major flaws of both the 'normal approximation' and the Clopper & Pearson approach for error estimation.

description: Maxwell's and the Drude-Born-Fedorov equations model EM-waves in chiral media. The Factorization method is generalized for inverse scattering by chiral objects. The case of a homogeneous chiral sphere is done analytically. Scattering by a chiral cylinder motivates the Factorization method for the vector Helmholtz equation. Numerical examples illustrate the theoretical results. Scattering from periodic chiral structures is another possible application of the generalized Factorization method.

description: We study the feasibility of a new generation axion helioscope, the most ambitious and promising detector of solar axions to date. We show that large improvements in magnetic field volume, x-ray focusing optics and detector backgrounds are possible beyond those achieved in the CERN Axion Solar Telescope (CAST). For hadronic models, a sensitivity to the axion-photon coupling of $\gagamma\gtrsim {\rm few} \times 10^{-12}$ GeV$^{-1}$ is conceivable, 1--1.5 orders of magnitude beyond the CAST sensitivity. If axions also couple to electrons, the Sun produces a larger flux for the same value of the Peccei-Quinn scale, allowing one to probe a broader class of models. Except for the axion dark matter searches, this experiment will be the most sensitive axion search ever, reaching or surpassing the stringent bounds from SN1987A and possibly testing the axion interpretation of anomalous white-dwarf cooling that predicts $m_a$ of a few meV. Beyond axions, this new instrument will probe entirely unexplored ranges of parameters for a large variety of axion-like particles (ALPs) and other novel excitations at the low-energy frontier of elementary particle physics.

Corotational Instability, Magnetic Resonances and Global Inertial-Acoustic Oscillations in Magnetized Black-Hole Accretion Discs

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Low-order, non-axisymmetric p-modes (also referred as inertial-acoustic modes) trapped in the inner-most region of hydrodynamic accretion discs around black holes, are plausible candidates for high-frequency quasi-periodic oscillations (QPOs) observed in a number of accreting black-hole systems. These modes are subject to global instabilities due to wave absorption at the corotation resonance (where the wave pattern frequency $ω/m$ equals the disc rotation rate $Ω$), when the fluid vortensity, $ζ=κ^2/(2ΩΣ)$ (where $κ$ and $Σ$ are the radial epicyclic frequency and disc surface density, respectively), has a positive gradient. We investigate the effects of disc magnetic fields on the wave absorption at corotation and the related wave super-reflection of the corotation barrier, and on the overstability of disc p-modes. For discs with a pure toroidal field, the corotation resonance is split into two magnetic resonances, where the wave frequency in the corotating frame of the fluid, $\tomega=ω-mΩ$, matches the slow magnetosonic wave frequency. Significant wave energy/angular momentum absorption occurs at both magnetic resonances, but with opposite signs. The combined effect of the two magnetic resonances is to reduce the super-reflection and the growth rate of the overstable p-modes. We show that even a subthermal toroidal field may suppress the overstability of hydrodynamic (B=0) p-modes. For accretion discs with mixed (toroidal and vertical) magnetic fields, two additional Alfven resonances appear, where $\tomega$ matches the local Alfven wave frequency. They further reduce the growth rate of p-modes. Our results suggest that in order for the non-axisymmetric p-modes to be a viable candidate for the observed high-frequency QPOs, the disc magnetic field must be appreciably subthermal, or other mode excitation mechanisms are at work.

Convective overshooting and production of s-nuclei in massive stars during their core He-burning phase

description: With the "post-processing" technique we explore the role of the convective overshooting on the production of s-nuclei in stellar models of different initial mass and metallicity ($15 \leq M_{ZAMS}/M_{\odot} \leq 25$; $10^{-4} \leq Z \leq 0.02$), considering a range of values for the parameter $f$, which determines the overall efficiency of convective overshooting.We find enhancements in the production of s-nuclei until a factor $\sim 6$ (measured as the average overproduction factor of the 6 s-only nuclear species with $60\lesssim A\lesssim90$) in all our models of different initial mass and metallicity with $f$ in the range $0.01{-}0.035$ (i.e. models with overshooting) compared to the production obtained with "no-overshooting" models (i.e. models with the same initial mass and metallicity, but $f=10^{-5}$). Moreover the results indicate that the link between the overshooting parameter $f$ and the s-process efficiency is essentially monotonic in all our models of different initial mass and metallicity. Also evident is the higher s-process efficiency when we progressively increase for a given f value both the mass of the models from 15 M$_\odot$ to 25 M$_\odot$ and the Z value from 10$^{-4}$ to 0.02. We also briefly discuss the possible consequences of these results for some open questions linked to the s-process weak component efficiency, as well as a "rule of thumb" to evaluate the impact of the convective overshooting on the yields of a generation of stars.

International Patent TRICEU REV26 Global Cancer cure 2025
Creators: name: Paradis, Sébastien
Publisher: name: Zenodo
Year: 2025

description: I took a meticulous and innovative approach to develop a robust, flawless international patent for TRICEU-REV26, ensuring it could withstand scrutiny from medical, scientific, and regulatory experts while meeting PCT filing standards. Recognizing the complexity of a theranostic platform targeting resistant cancers with 65-75% efficacy and tissue regeneration at 40-55%, I aimed to create a comprehensive and credible document.

I started by drafting a detailed patent framework, outlining the platform’s five modules—OmniSomes™, NanoMatrix™, StimuSense™, NEURA v2.0, and SentinelSense™—with precise technical specifications, such as nanoliposome sizes of 65-70 nm and microchannel porosity of 20-50 μm. I included preclinical data from 300 organoids (n=5-8, p<0.01) and aligned claims with recent literature, like Nano Letters and Nature Communications (2023-2024), to bolster credibility. To avoid overstatement, I moderated performance metrics, ensuring toxicity remained below 3%.

To refine this draft, I engaged multiple AI systems, including Grok 3 (built by xAI), to iteratively revise and challenge the content. I provided specific feedback, requesting:

Clarity and Precision: I asked for stronger justifications, such as bioprinting pressures of 75-85 kPa validated by CFD and rheology, and detailed protocols, like Q2-Q4 2025 preclinical tests with n=5 replicates.

Scientific Rigor: I ensured data consistency (e.g., efficacy at 65-75%, regeneration at 40-55%) and addressed potential objections, like immunogenicity below 1% and scalability through Lonza CMO.

Regulatory Compliance: I emphasized adherence to GLP/ICH E6 standards and freedom-to-operate analysis against Doxil and Organovo patents to prepare for FDA/EMA submissions.

Multilingual and Cost Adjustments: I requested versions in English and French, with costs converted to USD (1 EUR ≈ 1.1 USD), setting unit costs at $66-82.50 for global accessibility.

By challenging various AIs to critique and enhance the patent, I identified gaps, such as insufficient justification for replicates or ambiguous budgets, and incorporated advanced features like 4D bioprinting with holographic feedback and adaptive pressure control. This iterative process ensured exhaustive claims that comprehensively protected the invention’s compositions, methods, and synergies.

My approach—blending my oversight with AI-driven refinement—produced a bulletproof patent optimized for scientific credibility, regulatory approval by 2030, and commercial scalability (500 units by Q3 2026). It reflects my commitment to leveraging cutting-edge AI collaboration to drive innovation in nanomedicine.

description: We investigate the scenario where spatially separated parties perform measurements in randomly chosen bases on an N-partite Greenberger-Horne-Zeilinger state. We show that without any alignment of the measurements, the observers will obtain correlations that violate a Bell inequality with a probability that rapidly approaches 1 as N increases and that this probability is robust against noise. We also prove that restricting these randomly chosen measurements to a plane perpendicular to a common direction will always generate correlations that violate some Bell inequality. Specifically, if each observer chooses their two measurements to be locally orthogonal, then the N observers will violate one of two Bell inequalities by an amount that increases exponentially with N. These results are also robust against noise and perturbations of each observer's reference direction from the common direction.

description: Japan, the leading foreign market for American farm products, has developed a long-term policy of diversifying sources of its agricultural imports to hedge against supplies being reduced or shut off from major sources and to encourage other countries to purchase Japan's industrial products. Programs are underway for assisting developing countries to increase agricultural production. Implementation is primarily through Japan's foreign aid programs--both government and private enterprise participate. The commodities on which most emphasis is being placed are corn, grain sorghum, cassava (for animal feed), oilseeds, tropical fruits, and silk. Programs are underway in all developing regions of the world. Currently, the most ambitious programs are in Southeast Asia. By 1975, it seems reasonable to expect that Southeast Asia will be exporting to Japan 1.5 million to 2.0 million metric tons of corn and 200,000 to 300,000 tons of grain sorghum. A roughly equivalent amount of grain sorghum may be moving from Australia to Japan. Other items that are expected to show a significant increase in volume of imports by Japan by 1975 include dried cassava, tropical fruits and fruit products, raw silk, cotton, and tobacco.

description: A {\it gauge invariant} combination of LLe {\it sleptons} within the Minimal Supersymmetric Standard Model is one of the few inflaton candidates that can naturally explain population of the observable sector and creation of matter after inflation. After the end of inflation, the inflaton oscillates coherently about the minimum of its potential, which is a point of {\it enhanced gauged symmetry}. This results in bursts of non-perturbative production of the gauge/gaugino and (s)lepton quanta. The subsequent decay of these quanta is very fast and leads to an extremely efficient transfer of the inflaton energy to (s)quarks via {\it instant} preheating. Around 20% of the inflaton energy density is drained during every inflaton oscillation. However, all of the Standard Model degrees of freedom (and their supersymmetric partners) {\it do not} thermalize immediately, since the large inflaton vacuum expectation value breaks the electroweak symmetry. After about 100 oscillations -- albeit within one Hubble time -- the amplitude of inflaton oscillations becomes sufficiently small, and all of the degrees of freedom will thermalize. This provides by far the most efficient reheating of the universe with the observed degrees of freedom.

description: Predicting the statistics of realistic wave-chaotic scattering systems requires, in addition to random matrix theory, introduction of system-specific information. This paper investigates experimentally one aspect of system-specific behavior, namely the effects of short ray trajectories in wave-chaotic systems open to outside scattering channels. In particular, we consider ray trajectories of limited length that enter a scattering region through a channel (port) and subsequently exit through a channel (port). We show that a suitably averaged value of the impedance can be computed from these trajectories and that this can improve the ability to describe the statistical properties of the scattering systems. We illustrate and test these points through experiments on a realistic two-port microwave scattering billiard.

The stellar spectra were observed with FEROS/ESO, and the stellar atmospheric parameters of the 8 barium giant stars and 6 normal giants analyzed by us lie in the range 4300 < T_eff/K < 5300, -0.7 < [Fe/H] <= 0.12 and 1.5 <= log g < 2.9. Carbon and nitrogen abundances were derived by the spectral synthesis of molecular bands of C_2, CH and CN. For all the other elements, atomic lines were used to perform the spectral synthesis. A very large scatter was found when data from the literature were considered, mainly for the Mn abundances. We found that [Zn/Fe] correlates well with the heavy element excesses, its abundance clearly increasing as the heavy element excesses increase, a trend not shown by the [Cu/Fe] and [Mn/Fe] ratios. Also, the excess of Mn, Cu and Zn relative to heavy elements usually show an increasing trend toward higher metallicities. Our results suggest that a larger fraction of the synthesis of Zn is owed to massive stars than is the case of Cu, and that the contribution of the main-s process to the synthesis of both elements is small. We also conclude that Mn is mostly synthesized by SN Ia, and that a non-negligible fraction of the synthesis of Mn, Cu and Zn is owed to the weak s-process.

Forecasting of nonlinear extreme quantiles using copula models
Creators: name: Coia, Vincenzo
Publisher: name: University of British Columbia
Year: 2017

description: Forecasts of extreme events are useful in order to prepare for disaster. Such forecasts are usefully communicated as an upper quantile function, and in the presence of predictors, can be estimated using quantile regression techniques. This dissertation proposes methodology that seeks to produce forecasts that (1) are consistent in the sense that the quantile functions are valid (non-decreasing); (2) are flexible enough to capture the dependence between the predictors and the response; and (3) can reliably extrapolate into the tail of the upper quantile function. To address these goals, a family of proper scoring rules is first established that measure the goodness of upper quantile function forecasts. To build a model of the conditional quantile function, a method that uses pair-copula Bayesian networks or vine copulas is proposed. This model is fit using a new class of estimators called the composite nonlinear quantile regression (CNQR) family of estimators, which optimize the scores from the previous scoring rules. In addition, a new parametric copula family is introduced that allows for a non-constant conditional extreme value index, and another parametric family is introduced that reduces a heavy-tailed response to a light tail upon conditioning. Taken together, this work is able to produce forecasts satisfying the three goals. This means that the resulting forecasts of extremes are more reliable than other methods, because they more adequately capture the insight that predictors hold on extreme outcomes. This work is applied to forecasting extreme flows of the Bow River at Banff, Alberta, for flood preparation, but can be used to forecast extremes of any continuous response when predictors are present.

Nitrogen (N) in subducting slab resides in both sediments and altered oceanic crust (AOC). The extent of subduction-zone metamorphic devolatilization of N in these reservoirs determines the amount of remaining N for deep recycling. However, N behavior inside the subduction zone, particularly below the forearc region, remains poorly understood so far. Here, we studied the pillow-shaped epidote-blueschist facies meta-basalts (hereafter refer to as blueschists) in the Heilongjiang Complex in Northeast China, aiming to understand the N behavior during the early subduction stage. Results show that these blueschists contain N (13.9 to 122.6 ppm; average: 51.0 ppm) up to seven times higher than the AOC (including pillow lavas) entering global trenches (N < 19 ppm; average 7 ppm). The N concentrations of the blueschists correlate with the Ba and Th concentrations, indicating that significant N enrichment of the blueschists took place inside the subduction zone in addition to small N enrichment on seafloor. The N concentrations and δ15N values of the blueschists show two distinct mixing trends, indicating that two types of ammonium (NH4+) were added into the blueschists. One is characterized by relatively high abundance and positive δ15N value (~ +3‰), which can be attributed to the direct assimilation of NH4+ in metamorphic fluids derived from the sedimentary components in the mélange. The other is characterized by relatively low abundance and extremely low δ15N values (~ −16‰). This NH4+ is consistent with a product of abiotic reduction of sediment-derived N2. This study demonstrates that the labile N in sediments released during early subduction can be at least partially (if not all) re-fixed into the more refractory meta-igneous part of the subducting slab, which facilitates the retention of N for deep subduction and recycling.

description: The set of quantum Gaussian channels acting on one bosonic mode can be classified according to the action of the group of Gaussian unitaries. We look for bounds on the classical capacity for channels belonging to such a classification. Lower bounds can be efficiently calculated by restricting to Gaussian encodings, for which we provide analytical expressions.

description: In this thesis, we present a fabrication technology of Al/AlOx/Al Josephson junctions on Nb pads. The described technology gives the possibility of combining a variety of Nb-based superconducting circuits, like pi-junction phase-shifters with sub-micron Al/AlOx/Al junctions. Using this approach, we fabricated hybrid Nb/Al flux qubits with and without the SFS-junctions and studied dispersive magnetic field response of these qubits as well as their spectroscopy characteristics.

Monitoring miombo woodlands of Southern Africa with multi-source information in a model-based framework

description: Acquiring forest resources information for tropical developing countries is challenging due to financial and logistical constraints, yet this information is critical for enhancing management capability and engaging in initiatives such as Reducing Emissions from Deforestation and forest Degradation (REDD+). In this dissertation, I investigated innovative approaches to monitoring forest resources and deepened understanding of multi-source information (i.e., remote-sensing, environmental, and disturbance data) needs by examining methods using a model-based framework for assessment of a jurisdictional landscape in the miombo ecoregion of Zambia. I focused on percent canopy cover (CC) and above-ground biomass (AGB) within a National Forest Inventory (NFI) context because both are important for land management and REDD+. First, I compared multi-source information and four modeling methods to estimate CC and total forest area. Landsat outperformed RapidEye and a generalized additive model was most precise. Available soil water content (AWC), slope, distance to district capital, and texture of remotely sensed data were crucial predictor variables in improving estimates. Second, I used multi-source information and compared methods with and without predicted CC in three modeling methods to estimate total AGB. A nonlinear sigmoidal model was most precise when using predicted CC, AWC, pH, occurrence of late season fire, and the Normalized Difference Moisture Index as predictor variables. Third, I developed an innovative monitoring framework using time series classification and a stock-difference approach to estimate change in land cover and AGB over a 16-year annual time series of Landsat data. Forest/nonforest change trajectories were used to develop change classes relevant to underlying biotic and abiotic factors and provided ecologically meaningful context for land cover change and AGB change. Overall, predictor variables related to soil moisture, topography, shortwave infrared bands and texture of vegetation indices from remotely sensed data are vital to accurate models of CC and AGB. Genetic algorithms provide an opportune method for predictor variable selection across a diversity of modeling methods. Further, robust change estimates are feasible when using annual monitoring methods based on freely available, multi-source information. In conclusion, the model-based framework provides a precise, statistically sound, approach to estimating and mapping forest attributes within an NFI context.

description: It is theoretically known that a pair of phase conjugating surfaces can function as a perfect lens, focusing propagating waves and enhancing evanescent waves. However, the known experimental approaches based on thin sheets of nonlinear materials cannot fully realize the required phase conjugation boundary condition. In this paper we show that the ideal phase conjugating surface is in principle physically realizable and investigate the necessary properties of nonlinear and nonreciprocal particles which can be used to build a perfect lens system. The physical principle of the lens operation is discussed in detail and directions of possible experimental realizations are outlined.

description: The production of doubly charged Higgs bosons (H^{\pm\pm}) at the CERN LHC can give rise to distinctive multi-lepton signatures. The discovery potential of H^{\pm\pm} can be optimized by considering a search strategy which is sensitive to both of the dominant production mechanisms, q\bar q\to H^{++}H^{--} and q\bar {q'}\to H^{\pm\pm}H^{\mp}. We compare the discovery potential for the signatures of exactly four leptons and at least three leptons in the final state, using the same set of cuts. We have carried out fast detector simulations at the LHC for both signal and backgrounds for a wide range of values of the charged Higgs mass. We find that the use of the latter channel can substantially improve the detection prospects of the doubly charged Higgs boson at the LHC.
