description: We propose an economical model addressing the generation of the Inverse Seesaw mechanism from the spontaneous breaking of a local $U(1)_{B-L}$, with the Majorana masses of the sterile neutrinos radiatively generated from the dark sector. The field content of the Standard Model is extended by neutral scalars and fermionic singlets, and the gauge group is extended with a $U(1)_{B-L}$ and a discrete $\mathbb{Z}_4$ symmetries. Besides dynamically generating the Inverse Seesaw and thus small masses to the active neutrinos, our model offers two possible dark matter candidates, one scalar and one fermionic, stable thanks to a remnant $\mathbb{Z}_2$ symmetry. Our model complies with bounds and constraints form dark matter direct detection, invisible Higgs decays and $Z'$ collider searches for masses of the dark sector at the TeV scale.

Effective gluon mass and infrared fixed point in QCD

description: We report on a special type of solutions for the gluon propagator of pure QCD, obtained from the corresponding non-linear Schwinger-Dyson equation formulated in the Feynman gauge of the background field method. These solutions reach a finite value in the deep infrared and may be fitted using a massive propagator, with the crucial characteristic that the effective ``mass'' employed depends on the momentum transfer. Specifically, the gluon mass falls off as the inverse square of the momentum, as expected from the operator-product expansion. In addition, one may define a dimensionless quantity, which constitutes the generalization in a non-Abelian context of the universal QED effective charge. This strong effective charge displays asymptotic freedom in the ultraviolet whereas in the low-energy regime it freezes at a finite value, giving rise to an infrared fixed point for QCD.

Point-Cloud Deep Learning of Porous Media for Permeability Prediction

description: We propose a novel deep learning framework for predicting permeability of porous media from their digital images. Unlike convolutional neural networks, instead of feeding the whole image volume as inputs to the network, we model the boundary between solid matrix and pore spaces as point clouds and feed them as inputs to a neural network based on the PointNet architecture. This approach overcomes the challenge of memory restriction of graphics processing units and its consequences on the choice of batch size, and convergence. Compared to convolutional neural networks, the proposed deep learning methodology provides freedom to select larger batch sizes, due to reducing significantly the size of network inputs. Specifically, we use the classification branch of PointNet and adjust it for a regression task. As a test case, two and three dimensional synthetic digital rock images are considered. We investigate the effect of different components of our neural network on its performance. We compare our deep learning strategy with a convolutional neural network from various perspectives, specifically for maximum possible batch size. We inspect the generalizability of our network by predicting the permeability of real-world rock samples as well as synthetic digital rocks that are statistically different from the samples used during training. The network predicts the permeability of digital rocks a few thousand times faster than a Lattice Boltzmann solver with a high level of prediction accuracy.

Agricultural land evaluation in the Kailali District in Nepal : using resource inventory data as a basis for national land use planning
Creators: name: Shah, Pravakar Bickram
Publisher: name: University of British Columbia
Year: 2010

description: The objective of this research project was to demonstrate how biophysical information of the land resource survey in Nepal can be interpreted for land use planning and improvement of agricultural production. This was accomplished by devising a suitability rating scheme for six major crops presently grown in the study area. A modified F.A.O. suitability scheme was developed based on optimum, marginal and unsuitable conditions derived mostly from literature and local knowledge. Potential land use was determined for double and triple crop rotation schemes with and without irrigation. A suitability rating for each mapping unit was assigned, and based on the inherent physical and chemical soil limitations, the most appropriate crop rotation sequences were formulated. A comparison between current and proposed land use with and without irrigation was made in order to determine where expansion of certain crops and rotations are feasible and to justify the proposed land use over the existing one. This quantitative analysis showed that agricultural land can be increased by nearly 84% at the expense of forest land, which is at present degraded and not commercially viable. Increase in crop production is not only achievable by increasing the area for cultivation, but also by improving crop rotation and introducing irrigation. Based on currently obtained average yield, crop production can be increased by nearly 96% for improved land use without irrigation and 230% for improved land use with irrigation. These improvements are based on introducing double and triple crop rotation systems. Under more capital intensive management, such as irrigation, artificial fertilizers can be introduced and modest target yields can be obtained which are significantly higher than present yields. With such conditions, future overall production can be increased by nearly twelve times over current production. Long term fertilizer problems can be anticipated by knowing the inherent limitations of each mapping unit and using a Fertilizer Capability Classification Assessment scheme (FCC). It is hoped that by using the best crop rotation sequences, maximizing organic matter management and introducing artificial fertilizers, long term fertility and productivity can be maintained in the more intensively cultivated areas. The model developed is simple, easy to use and can be applied all to other Terai Districts in Nepal, where similar biophysical data are now available. This will facilitate national land use planning, help in the identification of new potential agricultural areas and provide a basis for increasing the national agricultural production.

description: Introduced and investigated new kind of percolation problem - so called internal percolation problem (IP). In usual percolation problem current flows from top to bottom of the system and here it can be called as external percolation problem (EP) despite of the IP case when voltage is applied to the system through bars which are inside of the hole in system. EP problem has two major parameters: M size of system and a0 size of inclusion, lattice size etc. IP holds one more parameter the size of hole - L. Results of computer simulation show that critical indexes of conductance for IP problem are very close to those in EP problem. In opposite indexes of relative spectral noise density of 1/f noise and higher moments are really differs from EP problem. The source of such behaviour is discussed.

Auf dem Umschlag wurde später von fremder Hand beschriftet "auch 1917 u. 1918/19 benutzt".
Bei der Aufbereitung für die Digitalisierung ist nur ein einziges Doppelblatt (ohne Bl.-Nr.), beschriftet mit "Winter 1918/19", vor Bl. 11 gefunden worden. Besser passen würde es vor Bl. 18. Am besten aber passt es in die Unterlagen aus dem Jahr 1918/19, womit die Daten von 18.11.1918 und 23.11.1918, beide auf dem Doppelbl. notiert, neu an anderer Stelle wieder als Beginn der Vorlesung vorhanden sind. Entsprechend hier entnommen und in die Unterlagen von 1918/19 eingeordnet (in der Abfolge des gesamten Materials in der nächsten Einheit platziert).
Die Doppelblätter, die jeweils pro Doppelbl. für 4 S. Text lassen, sind numerisch aufsteigend abgelegt (es sind alle Nrn. vorh.) und sind meist explizit mit Vorlesungsdaten des Jahres 1915 beschriftet. Die Bl. wurden als Umschläge für Bl. von kleinerem Format verwendet. In fast jedem Doppelbl. liegt ein kleineres Doppelbl. der Vorlesung aus dem Jahr 1916/17. Im letzten Doppelbl. liegen vier Doppelbl. zur Vorlesung von 1917, deren anschliessende letzte zwei Doppelblätter bis zum Schluss der Vorlesung sich nicht hier, sondern bei den Unterlagen von 1918/19 am Schluss befinden (sie wurden dort offenbar (später?) eingeordnet, weil damals während der Vorlesung 1919 einiges "ganz beiseite" gelassen werden musste).
Im Rahmen der Digitalisierung wurde es möglich, sowohl die vorgefundene Ablage mit der Einordnung der Innenblätter abzubilden, als auch zusätzlich die jahrgangsweise Zuordnung der Teile explizit zu benennen.
Das Doppelblatt mit der Beschriftung "Winter 1918/19" wurde wie beschrieben neu eingeordnet.

description: We study high-pt jets from QCD and from highly-boosted massive particles such as tops, W, Z and Higgs, and argue that infrared-safe observables can help reduce QCD backgrounds. Jets from QCD are characterized by different patterns of energy flow compared to the products of highly-boosted heavy particle decays, and we employ a variety of jet shapes, observables restricted to energy flow within a jet, to explore this difference. Results from Monte Carlo generators and arguments based on perturbation theory support the discriminating power of the shapes we refer to as planar flow and angularities. We emphasize that for massive jets, these and other observables can be analyzed perturbatively.

Thermodynamic guidelines for the prediction of hydrogen storage reactions and their application to destabilized hydride mixtures

description: We propose a set of thermodynamic guidelines aimed at facilitating more robust screening of hydrogen storage reactions. The utility of the guidelines is illustrated by reassessing the validity of reactions recently proposed in the literature, and through vetting a list of more than 20 candidate reactions based on destabilized LiBH4 and Ca(BH4)2 borohydrides. Our analysis reveals several new reactions having both favorable thermodynamics and relatively high hydrogen densities (5-9 wt.% H2 & 85-100 g H2 /L), and demonstrates that chemical intuition alone is not sufficient to identify valid reaction pathways.

description: The increasing number of transiting planets raises the possibility of finding changes in their transit time, duration and depth that could be indicative of further planets in the system. Experience from eclipsing binaries indeed shows that such changes may be expected. A first obvious candidate to look for a perturbing planet is GJ 436, which hosts a hot transiting Neptune-mass planet in an eccentric orbit. Ribas et al. (2008) suggested that such eccentricity and a possible change in the orbital inclination might be due to a perturbing small planet in a close-in orbit. A radial velocity signal of a 5 M_earth planet close to the 2:1 mean-motion resonance seemed to provide the perfect candidate. Recent new radial velocities have deemed such signal spurious. Here we put all the available information in context and we evaluate the possibility of a small perturber to GJ 436 b to explain its eccentricity and possible inclination change. In particular, we discuss the constraints provided by the transit time variation data. We conclude that, given the current data, the close-in perturber scenario still offers a plausible explanation to the observed orbital and physical properties of GJ 436 b.

description: The simulation of the neutrino interaction is a crucial step in the simulation chain of a neutrino experiment. The different processes taking part in the neutrino scattering on a nucleus require several approximations in order to make the simulation possible and to realize reasonable computation times. This can be realised in different ways, e.g. by parametrised models for the different scattering processes and energy regimes as it is implemented in GENIE. The GiBUU neutrino generator utilises the Boltzmann-Uehling-Uhlenbeck equation to simulate the particle flow after the neutrino interactions, the so-called final state interactions. The detector-specific results in form of the visible energy in the detector after the light propagation simulation and the KM3NeT event reconstruction are presented. In addition to that, the comparison to the GENIE based simulation environment in KM3NeT (gSeaGen) is drawn.

description: We investigate the nature of the recently catalogued star cluster candidate FSR584, which is projected in the direction of the molecular cloud W3 and may be the nearest globular cluster to the Sun. 2MASS CMDs, the stellar radial density profile, and proper motions are employed to derive fundamental and structural parameters. The CMD morphology and the radial density profile show that FSR584 is an old star cluster. With proper motions, the properties of FSR584 are consistent with a metal-poor globular cluster with a well-defined turnoff and evidence of a blue horizontal-branch. FSR584 might be a Palomar-like halo globular cluster that is moving towards the Galactic plane. The distance from the Sun is approx 1.4kpc, and it is located at approx 1kpc outside the Solar circle. The radial density profile is characterized by a core radius of rc=0.3+/-0.1 pc. However, we cannot exclude the possibility of an old open cluster. Near-infrared photometry coupled to proper motions support the scenario where FSR584 is a new globular cluster in the Galaxy. The absorption is A_V=9.2+/-0.6$, which makes it a limiting object in the optical and explains why it has so far been overlooked

description: The use of nanoparticles for intracellular drug delivery could reduce the toxicity and side effects of the drug but, the uptake of these nanocarriers could induce adverse effects on cells and tissues after their incorporation. Macrophages play a central role in host defense and are responsible for in vivo nanoparticle trafficking. Assessment of their defense capacity against pathogenic micro-organisms after nanoparticle uptake, is necessary to prevent infections associated with nanoparticle therapies. In this study, the effects of hollow mesoporous SiO2-CaO nanospheres labeled with fluorescein isothiocyanate (FITC-NanoMBGs) on the function of peritoneal macrophages was assessed by measuring their ability to phagocytize Candida albicans expressing a red fluorescent protein. Two macrophage-fungus ratios (MOI 1 and MOI 5) were used and two experimental strategies were carried out: a) pretreatment of macrophages with FITC-NanoMBGs and subsequent fungal infection; b) competition assays after simultaneous addition of fungus and nanospheres. Macrophage pro-inflammatory phenotype markers (CD80 expression and interleukin 6 secretion) were also evaluated. Significant decreases of CD80+ macrophage percentage and interleukin 6 secretion were observed after 30 min, indicating that the simultaneous incorporation of NanoMBG and fungus favors the macrophage noninflammatory phenotype. The present study evidences that the uptake of these nanospheres in all the studied conditions does not alter the macrophage function. Moreover, intracellular FITCNanoMBGs induce a transitory increase of the fungal phagocytosis by macrophages at MOI 1 and after a short time of interaction. In the competition assays, as the intracellular fungus quantity increased, the intracellular FITC-NanoMBG content decreased in a MOI- and timedependent manner...

description: We consider baryon vertices within the gauge/gravity correspondence for a class of curved backgrounds. The holographic description based on the N=4 SYM theory for SU(N) allows classical solutions representing bound states of k-quarks with k less than or equal to N. We construct the corresponding classical configurations and perform a stability analysis. We present the details for the theory at the conformal point and at finite temperature and show that there is a critical value of k, below which there is instability. This may also arise when the baryon reaches a critical size. We also extend our treatment to magnetically charged baryon vertices.

description: Electrocardiogram (ECG) has been widely used for emotion recognition. This paper presents a deep neural network based on convolutional layers and a transformer mechanism to detect stress using ECG signals. We perform leave-one-subject-out experiments on two publicly available datasets, WESAD and SWELL-KW, to evaluate our method. Our experiments show that the proposed model achieves strong results, comparable or better than the state-of-the-art models for ECG-based stress detection on these two datasets. Moreover, our method is end-to-end, does not require handcrafted features, and can learn robust representations with only a few convolutional blocks and the transformer component.

description: Due to the high cost and environmental instability of antibodies, there is precedent for developing synthetic molecular recognition agents for use in diagnostic sensors. Molecular imprinting was first investigated as a method for improving selectivity of crosslinked polymer hydrogels. However, the lysozyme-imprinted polymers exhibited high cross-reactivity and did not afford the polymer with improved selectivity. Instead, the observed cross-reactivity prompted the investigation of charge-containing, non-imprinted polymers as differential protein receptors. To this end, a set nanogels were synthesized by copolymerizing N-isopropylacrylamide with methacrylic acid, followed by a post-synthesis modification. Specifically, a carbodiimide coupling scheme was used to introduce sulfate, guanidinium, secondary amine, or primary amine groups. As expected, modification of the ionizable groups in the network changed the physicochemical and protein binding properties of the nanogels. For high affinity protein-polymer interactions, turbidity of the nanogel solution increased, while for low affinity interactions minimal change in turbidity was observed. Thus, relative turbidity was used as input for multivariate analysis. Turbidimetric assays were performed in two buffers of different pH (i.e., 7.4 and 5.5), but comparable ionic strength, in order to improve differentiation. Using both buffers, it was possible to achieve 100% classification accuracy of eleven model protein biomarkers with as few as two of the nanogel receptors. Subsequently, these polymeric receptors were synthesized on the surface of silica-gold nanoshells to develop a diagnostic biosensor based on localized surface plasmon resonance (LSPR). In particular, the sensitivity of LSPR to changes in local refractive index was exploited to enable detection of three biomarkers (lysozyme, lactoferrin, and IgG) of Sjögren’s syndrome, an autoimmune disease that primarily affects the exocrine system. Overall, the polymer-gold nanomaterial composites developed in this dissertation provide a promising platform for developing affordable and environmentally robust diagnostic biosensors.

description: We discuss experimental studies of the interaction between a nanoscopic object and a photonic crystal membrane resonator of quality factor Q=55000. By controlled actuation of a glass fiber tip in the near-field of a photonic crystal, we constructed a complete spatio-spectral map of the resonator mode and its coupling with the fiber-tip. On the one hand, our findings demonstrate that scanning probes can profoundly influence the optical characteristics and the near-field images of photonic devices. On the other hand, we show that the introduction of a nanoscopic object provides a low-loss method for on-command tuning of a photonic crystal resonator frequency. Our results are in a very good agreement with the predictions of a combined numerical/analytical theory.

description: We compute the statistical entropy of the three charge (D1-D5-p) five dimensional black hole to sub-leading order in a large charge expansion. We find an agreement with the macroscopic calculation of the Wald entropy in R^2 corrected supergravity theory. The two calculations have a overlapping regime of validity which is not the Cardy regime. We use this result to clarify the 4d-5d lift for black holes on Taub-NUT space. In particular, we compute sub-leading corrections to the formula S^{4d} = S^{5d}. In the microscopic analysis, this correction arises from excitations bound to the Taub-NUT space. In the macroscopic picture, the difference is accounted by a mechanism present in a higher derivative theory wherein the geometry of the Taub-NUT space absorbes some of the electric charge.

description: We consider the wide class of few-particle systems that have some analog of the thermodynamic laws. These systems are characterized by the distributions that are determined by the Hamiltonian and satisfy the Liouville equation. Few-particle systems of this class are described by a non-holonomic constraint: the power of non-potential forces is directly proportional to the velocity of the elementary phase volume change. The coefficient of this proportionality is determined by the Hamiltonian. In the general case, the examples of the few-particle systems of this class are the constant temperature systems, canonical-dissipative systems, and Fermi-Bose classical systems.

description: (Abridged) We present multi-epoch imaging of the T5.0+T5.5 binary 2MASS J1534-2952AB obtained with the Keck laser guide star adaptive optics system. Combined with an extensive (re-)analysis of archival HST imaging, we find a total mass of 0.056+/-0.003 Msun (59+/-3 Mjup). This is the first field binary for which both components are directly confirmed to be substellar. This is also the coolest and lowest mass binary with a dynamical mass determination to date. Using evolutionary models, we derive an age of 0.78+/-0.09 Gyr for the system, and we find Teff = 1028+/-17 K and 978+/-17 K and masses of 0.0287+/-0.0016 Msun (30.1+/-1.7 Mjup) and 0.0269+/-0.0016 Msun (28.2+/-1.7 Mjup) for the individual components. These precise measurements generally agree with previous studies of T dwarfs and affirm the current theoretical models. However, (1) the temperatures are about 100 K cooler than derived for similar objects and suggest that the ages of field brown dwarfs may be overestimated. Also, (2) the H-R diagram positions are discrepant with current predictions. While this may arise from large errors in the evolutionary models, the likely cause is a modest (~100 K) overestimate in temperatures determined from model atmospheres. We discuss future tests of theory as the sample of substellar dynamical masses increases. In particular, we suggest that low-mass field binaries with dynamical masses ("mass benchmarks") can serve as reference points for Teff and log(g) and thereby constrain ultracool atmosphere models, as good as or even better than single brown dwarfs with age estimates ("age benchmarks").

description: We have conducted a deep ($15 \la r \la 23$), 20 night survey for transiting planets in the intermediate age ($\sim 550 {\rm Myr}$) open cluster M37 (NGC 2099) using the Megacam wide-field mosaic CCD camera on the 6.5m Multiple Mirror Telescope (MMT). In this paper we present a catalog and light curves for 1445 variable stars; 1430 (99%) of these are new discoveries. We have discovered 20 new eclipsing binaries and 31 new short period ($P < 1 {\rm day}$) pulsating stars. The bulk of the variables are most likely rapidly rotating young low-mass stars, including a substantial number ($\ga 500$) that are members of the cluster. We identify and analyze five particularly interesting individual variables including a previously identified variable which we suggest is probably a hybrid $γ$ Doradus/$δ$ Scuti pulsator, two possible quiescent cataclysmic variables, a detached eclipsing binary (DEB) with at least one $γ$ Doradus pulsating component (only the second such variable found in an eclipsing binary), and a low mass ($M_{P} \sim M_{S} \sim 0.6 M_{\odot}$) DEB that is a possible cluster member. A preliminary determination of the physical parameters for the DEB+$γ$ Doradus system yields $M_{P} = 1.58 \pm 0.04 M_{\odot}$, $M_{S} = 1.58 \pm 0.04 M_{\odot}$, $R_{P} = 1.39 \pm 0.07 R_{\odot}$ and $R_{S} = 1.38 \pm 0.07 R_{\odot}$.

description: The crossover between a free magnetic moment phase and a Kondo phase in low dimensional disordered metals with dilute magnetic impurities is studied. We perform a finite size scaling analysis of the distribution of the Kondo temperature as obtained from a numerical renormalization group calculation of the local magnetic susceptibility and from the solution of the self-consistent Nagaoka-Suhl equation. We find a sizable fraction of free (unscreened) magnetic moments when the exchange coupling falls below a disorder-dependent critical value $J_{\rm c}$. Our numerical results show that between the free moment phase due to Anderson localization and the Kondo screened phase there is a phase where free moments occur due to the appearance of random local pseudogaps at the Fermi energy whose width and power scale with the elastic scattering rate $1/τ$.

description: The Australia Telescope 20 GHz (AT20G) Survey is a blind survey of the whole Southern sky at 20 GHz (with follow-up observations at 4.8 and 8.6 GHz) carried out with the Australia Telescope Compact Array (ATCA) from 2004 to 2007. The Bright Source Sample (BSS) is a complete flux-limited subsample of the AT20G Survey catalogue comprising 320 extragalactic (|b|>1.5 deg) radio sources south of dec = -15 deg with S(20 GHz) > 0.50 Jy. Of these, 218 have near simultaneous observations at 8 and 5 GHz. In this paper we present an analysis of radio spectral properties in total intensity and polarisation, size, optical identifications and redshift distribution of the BSS sources. The analysis of the spectral behaviour shows spectral curvature in most sources with spectral steepening that increases at higher frequencies (the median spectral index α, assuming S\propto ν^α, decreases from α_{4.8}^{8.6}=0.11 between 4.8 and 8.6 GHz to α_{8.6}^{20}=-0.16 between 8.6 and 20 GHz), even if the sample is dominated by flat spectra sources (85 per cent of the sample has α_{8.6}^{20}>-0.5). The almost simultaneous spectra in total intensity and polarisation allowed us a comparison of the polarised and total intensity spectra: polarised fraction slightly increases with frequency, but the shapes of the spectra have little correlation. Optical identifications provided an estimation of redshift for 186 sources with a median value of 1.20 and 0.13 respectively for QSO and galaxies.

description: Polaritons are the collective excitations of many atoms dressed by resonant photons, which can be used to explain the slow light propagation with the mechanism of electromagnetically induced transparency. As quasi-particles, these collective excitations possess the typical feature of the matter particles, which can be reflected and deflected by the inhomogeneous medium in its spatial motion with some velocity. In this paper we develop a quantum theory to systematically describe the spatial motion of polaritons in inhomogeneous magnetic and optical fields. This theoretical approach treats these quasi-particles through an effective Schrödinger equation with anisotropic depression that the longitudinal motion is like a ultra-relativistic motion of a "slow light velocity" while the transverse motion is of non-relativity with certain effective mass. We find that, after passing through the EIT medium, the light ray bends due to the spatial-dependent profile of external field. This phenomenon explicitly demonstrates the exotic corpuscular property of polaritons with anisotropic nature.

description: We consider two very different models of the flux tube linking two heavy quarks: a string linking the matter fields and a Coulombic description of two separately gauge invariant charges. We compare how close they are to the unknown true ground state in compact U(1) and the SU(2) Higgs model. Simulations in compact U(1) show that the string description is better in the confined phase but the Coulombic description is best in the deconfined phase; the last result is shown to agree with analytical calculations. Surprisingly in the non-abelian theory the Coulombic description is better in both the Higgs and confined phases. This indicates a significant difference in the width of the flux tubes in the two theories.

description: The concept of ‘political energy’ is often treated as merely a rhetorical synonym for enthusiasm and active engagement. However, as Bruce Clarke’s Energy Forms argues there is an allegorical traffic of ideas between politics and science that reaches an apotheosis in the early-twentieth century interest in energy. In the field of the ‘energy-humanities’ inaugurated by Clarke, the work of George Sorel remains largely overlooked. Situating itself in this field, my paper investigates the interplay of science and politics in Sorel’s work. I contend that Sorel, influenced by Vico’s ideogeneitic law anticipates Clarke’s allegorical framework. Paralleling Henri Bergson’s attempts to rethink the novelty of life in the post-thermodynamic framework of energy, I argue that models from science (Brownian motion and friction) underlie Sorel’s conceptions of political myth and class antagonism. While these remain inchoate in Sorel’s works, I conclude with the suggestion that these traces are completed in Ernst Jünger’s conception of ‘total mobilization’.
