description: We compute three-body nuclear forces at short distances by using the nuclear matrix model of holographic QCD proposed in our previous paper with P. Yi. We find that the three-body forces at short distances are repulsive for (a) aligned three neutrons with averaged spins, and (b) aligned proton-proton-neutron / proton-neutron-neutron. These indicate that in dense states of neutrons such as cores of neutron stars, or in Helium-3 / tritium nucleus, the repulsive forces are larger than the ones estimated from two-body forces only.

description: The road to Limuru, Kenya runs beside a mission hospital named Nazareth; this much is true. In these fictional accounts, if the walls — even when topped by glass shards — can be breached by violence, if troubles come inside the gigantic gate, the characters nonetheless discover that compassion, too, can invade. As they care for the sick, they pay the personal costs of belonging to this high, green, misty ridge in Africa during the AIDS epidemic and the ascendancy of modern ways.

description: Der autotypische Rasterdruck, bei dem die Druckpunkte regelmäßig angeordnet sind und die Durchmesser der Druckpunkte entsprechend dem Tonwert variieren, entspricht einem Amplitudenmodulationsverfahren. Demgegenüber ist ein Bildaufbau mittels gleichgroßer Druckpunkte, die stochastisch verteilt und dem Tonwert entsprechend dicht angeordnet sind, ein Frequenzmodulationsverfahren. Der frequenzmodulierte Bildaufbau ist im Offsetdruck probeweise realisiert worden. Gegenüber dem konventionellen autotypischen Rasterdruck weist er Vorteile hinsichtlich der Farbwirkung, des Auflösungsvermögens und des Kontrastes auf. Zudem führt er im Auflagendruck zu einem stabileren Ergebnis.

description: We give a pedagogical introduction to static spherically symmetric solutions in models of New GR, both explaining the basics and showing how all such vacuum solutions can be obtained in elementary functions. In doing so, we coherently introduce the full landscape of these modified teleparallel spacetimes, and find a few special cases. The equations of motion are turned into a very nice and compact form by using the Levi-Civita divergence of the torsion-conjugate; and generalised Bianchi identities are briefly discussed. Another important point we make is that a convenient choice of the radial variable might be instrumental for success of similar studies in other modified gravity models.

description: Aims: We study possible signs of asymmetry in the luminous Type IIn SN2010jl, to obtain independent information on the explosion geometry. Methods: We obtained optical linear spectropolarimetry of SN2010jl two weeks after the discovery, in the spectral range 3700-8800 A. Results: The object exhibits a continuum polarization at a very significant and almost constant level (1.7-2.0%). Marked line depolarization is seen at the positions of the strongest emission features, like Halpha and Hbeta. This implies that the line forming region is well above the photosphere. The continuum polarization level (1.7-2.0%) indicates a substantial asphericity, of axial ratio <=0.7. The almost complete depolarization seen at Halpha suggests a very low level of interstellar polarization (<=0.3%). This rules out the presence of relevant amounts of dust in the progenitor environment at the time of our observations. From a polarimetric point of view, SN2010jl appears to be very similar to the two other well studied Type IIn SNe 1997eg and 1998S, establishing a strong link within this class of objects.

description: If a system falls through a black hole horizon, then its information is lost to an observer at infinity. But we argue that the {\it accessible} information is lost {\it before} the horizon is crossed. The temperature of the hole limits information carrying signals from a system that has fallen too close to the horizon. Extremal holes have T=0, but there is a minimum energy required to emit a quantum in the short proper time left before the horizon is crossed. If we attempt to bring the system back to infinity for observation, then acceleration radiation destroys the information. All three considerations give a critical distance from the horizon $d\sim \sqrt{r_H\over ΔE}$, where $r_H$ is the horizon radius and $ΔE$ is the energy scale characterizing the system. For systems in string theory where we pack information as densely as possible, this acceleration constraint is found to have a geometric interpretation. These estimates suggest that in theories of gravity we should measure information not as a quantity contained inside a given system, but in terms of how much of that information can be reliably accessed by another observer.

description: We investigate the properties of hot and/or dense matter in QCD-like theories with quarks in a (pseudo)real representation of the gauge group using the Nambu-Jona-Lasinio model. The gauge dynamics is modeled using a simple lattice spin model with nearest-neighbor interactions. We first keep our discussion as general as possible, and only later focus on theories with adjoint quarks of two or three colors. Calculating the phase diagram in the plane of temperature and quark chemical potential, it is qualitatively confirmed that the critical temperature of the chiral phase transition is much higher than the deconfinement transition temperature. At a chemical potential equal to half of the diquark mass in the vacuum, a diquark Bose-Einstein condensation (BEC) phase transition occurs. In the two-color case, a Ginzburg-Landau expansion is used to study the tetracritical behavior around the intersection point of the deconfinement and BEC transition lines, which are both of second order. We obtain a compact expression for the expectation value of the Polyakov loop in an arbitrary representation of the gauge group (for any number of colors), which allows us to study Casimir scaling at both nonzero temperature and chemical potential.

description: Nanotechnology  is  the  most  promising  field  for  generating  new  applications  in  medicine.
Green synthesis of AgNPs is an efficient, fast, cheap, non-toxic, simple, and eco-friendly than
commonly used physicochemical methods. The  present  study  focuses  on  green  synthesis,
characterization,  antibacterial  and  antioxidant  activities  of  AgNPs  synthesized  using
aqueous extract of Moringa stenopetala leaves. The green synthesis of AgNPs was done by
using  aqueous  extract  of  Moringa  stenopetala  leaves  and  silver  nitrate  solution at  room
temperature. Formation of AgNPs was confirmed by the appearance of dark-brown color of
the mixture and further confirmed by spectral analysis. Parameters affecting the formation of
AgNPs were investigated and optimized. Optimum heating time required for the preparation
of aqueous extract of Moringa stenopetala leaves was 15 minutes. It was found that 90 mL of
1 mM of silver nitrate solution and 15 mL of aqueous extract of Moringa stenopetala leaves
were more  favorable  for  maximum  production  of  AgNPs  with  a  yield  of  97.14  %. UV-Vis
spectrum of synthesized AgNPs shows a peak at 412 nm after 24 hours of incubation time.
FTIR spectral analysis indicated the involvement of carbonyl (-C=O), hydroxyl (-O-H) and
amine  (-N-H)  functional  groups in  the  formation  and  stabilization of  AgNPs. The  XRD
pattern showed the face centered cubic structure of synthesized AgNPs with average particle
size of 11.44 nm. The results of the present study revealed that synthesized AgNPs showed
stronger antibacterial activity against E. coli than S. aureus. The present study showed that
synthesized AgNPs has better antioxidant activity than standard ascorbic acid. Synthesized
AgNPs had an efficient antibacterial and antioxidant activities.

description: The chiral magnetic wave (CMW) is a macroscopic quantum phenomenon that arises due to the mixing of the electric and chiral charge oscillations induced by the chiral anomaly. In this study we report the first quantum simulation (on classical hardware) of the real-time dynamics of CMWs in Schwinger model. Our quench protocol is the following: at $t=0$ we suddenly place an electric dipole at the middle of our lattice. Due to chiral anomaly, this dipole excites the CMW that propagates towards the edges of the lattice. In Schwinger model tuned to the conformal critical point (at $θ= π$, $m/g \simeq 0.2$), we find a gapless linear CMW that propagates with the speed of light. For massless Schwinger model ($θ=0, m=0$), we find a gapped linear CMW, in accord with previous analytical analyses. For massive Schwinger model (that is dual to strongly interacting bosonic theory), we enter the new regime of nonlinear CMWs, where we find a surprise. Specifically, for $m/g > 1$, the frequency of electric charge oscillations becomes much smaller than the frequency of the oscillations of the chiral charge. For $m/g =4$, we find a solution corresponding to a nearly static electric dipole with fast oscillations of the chiral charge confined within. We call this solution a "thumper" and study its properties in detail.

description: Using the data from the Rossi X-Ray Timing Explorer satellite, we investigate the spectral evolution along a "Z" track and a "v" track on the hardness-intensity diagrams of the first transient Z source XTE J1701-462. The spectral analyses suggest that the inner disk radius depends on the mass accretion rate, in agreement with the model prediction, R_in \propto ((dM/dt)_disk)^{2/7}, for a radiation pressure dominated accretion disk interacting with the magnetosphere of a neutron star (NS). The changes in the disk mass accretion rate (dM/dt)_disk are responsible for the evolution of the "Z" or "v" track. The radiation pressure thickens the disk considerably, and also produces significant outflows. The NS surface magnetic field strength, derived from the interaction between the magnetosphere and the radiation pressure dominated accretion disk, is ~(1--3)X10^9 G, which is possibly between normal atoll and Z sources. A significant hard tail is detected in the horizontal branches and we discuss several possible origins of the hard tail.

base  ligand were synthesized  through treatment of the Schiff base ligand with  the corresponding
metal halides, normally by heating the Schiff base  ligand  in the presence of  the metal salt under
reflux conditions  [2].  The  resulting  metal complexes were found to be crystalline  which have been

along with magnetic data suggest square planer geometry for Co(II) and Ni(II) complexes. The FTIR  spectra determined  the υ(C=N) stretching  vibration  found in the free ligand at 1627 cm

the  rate  o f  photodegradation  of  C R  was  also  investigated.  The  experimental  results
showed that  CR  degradation  depends  on  the  annealing  temperature  and alumina  content.
In  all  cases,  .he  photocatalytic  activity  gradually  increased  with  increasing  alumina

description: We build an exact inhomogeneous universe composed of a central flat Friedmann zone up to a small redshift $z_1$, a thick shell made of anisotropic matter, an hyperbolic Friedmann metric up to the scale where dimming galaxies are observed ($z\simeq 1.7$) that can be matched to a hyperbolic Lemaître-Tolman-Bondi spacetime to best fit the WMAP data at early epochs. We construct a general framework which permits us to consider a non-uniform clock rate for the universe. As a result, both for a uniform time and a uniform Hubble flow, the deceleration parameter extrapolated by the central observer is always positive. Nevertheless, by taking a non-uniform Hubble flow, it is possible to obtain a negative central deceleration parameter, that, with certain parameter choices, can be made the one observed currently. Finally, it is conjectured a possible physical mechanism to justify a non-uniform time flow.

Linking sediment supply, channel morphology, and aquatic habitat in forested, gravel-bed streams : spatial and temporal considerations
Creators: name: Reid, David A.
Publisher: name: University of British Columbia
Year: 2019

description: Gravel-bed streams in mountain environments are complex systems which respond unpredictably to episodic inputs of sediment from hillslopes. Stream channel response to episodic sediment supply has implications for channel morphology, stability, and aquatic habitat. While insight into the behaviour of these systems can be gained from numerical models and physical experiments, a paucity of long-term, comprehensive, and multi-scale field data has limited researchers’ ability to describe channel response to episodic sediment supply, and to situate this response in a broader landscape context. This thesis aims to overcome these limitations by examining long-term channel dynamics in response to episodic sediment supply and variable wood loading and then linking this variability to modeled aquatic habitat for juvenile salmonids. A 45 year field dataset from Carnation Creek, a small forested, gravel-bed stream located in a deglaciated catchment on coastal British Columbia, is used for analysis. Results indicate that temporal patterns of sediment storage are governed by the sediment conditions and local erosional and depositional processes, while spatial patterns are associated with sediment travel distance statistics. A conceptual model is proposed which presents channel response to episodic supply as a function of channel position downstream relative to colluvial input. In-stream wood is also found to influence channel morphology: logjams impact sediment throughput and lead to locations of elevated sediment storage, which decay exponentially over a 10-20 year period. A wood budget model indicates that wood loads will take up to 200 years to recover following riparian timber harvesting, with long-lasting implications for channel morphology. Modeled habitat for juvenile salmonids, simulated using Carnation Creek topographic and wood data, is found to vary through time by up to a factor of ten as a function of variable channel morphology and wood abundance. These results are found to support a conceptual model which links the contribution to habitat variability from channel morphology to a watershed’s sediment supply regime. Collectively, this work has improved our understanding of how episodic sediment supply and wood impact channel morphology, sediment storage, and aquatic habitat in a forested, gravel-bed stream over the long term.

Discovery and Monitoring of a new Black Hole Candidate XTE J1752-223 with RXTE: RMS spectrum evolution, BH mass and the source distance

description: We report on the discovery and monitoring observations of a new galactic black hole candidate XTE J1752-223 by Rossi X-ray Timing Explorer (RXTE). The new source appeared on the X-ray sky on October 21 2009 and was active for almost 8 months. Phenomenologically, the source exhibited the low-hard/high-soft spectral state bi-modality and the variability evolution during the state transition that matches standard behavior expected from a stellar mass black hole binary. We model the energy spectrum throughout the outburst using a generic Comptonization model assuming that part of the input soft radiation in the form of a black body spectrum gets reprocessed in the Comptonizing medium. We follow the evolution of fractional root-mean-square (RMS) variability in the RXTE/PCA energy band with the source spectral state and conclude that broad band variability is strongly correlated with the source hardness (or Comptonized fraction). We follow changes in the energy distribution of rms variability during the low-hard state and the state transition and find further evidence that variable emission is strongly concentrated in the power-law spectral component. We discuss the implication of our results to the Comptonization regimes during different spectral states. Correlations of spectral and variability properties provide measurements of the BH mass and distance to the source. The spectral-timing correlation scaling technique applied to the RXTE observation during the hard-to-soft state transition indicates a mass of the BH in XTE J1752-223 between 8 and 11 solar masses and a distance to the source about 3.5 kiloparsec.

Scalp and intracranial EEG quantitative analysis : robust detection and prediction of epileptic seizures
Creators: name: Hussein, Ramy
Publisher: name: University of British Columbia
Year: 2019

description: Epilepsy is a common neurological disorder that affects over 90 million people globally — 30-40% of whom do not respond to medication. Electroencephalogram (EEG) is the prime tool that has been widely used for the diagnosis and management of epilepsy. As the visual inspection of long-term EEG is tedious, expensive, and time-consuming, research in the EEG-based methods to automatically detect and predict epileptic seizures has been very active. This thesis studies how to leverage the temporal, spectral, and spatial information in the EEG data to accurately detect and also predict seizures. To automatically detect epileptic seizures, we first introduce a computationally-efficient method that detects a seizure within a very short time of its onset. It relies on a computationally-simple feature extraction method based on LASSO regression and extracts the prominent EEG seizure-associated features in a time-efficient manner, achieving high seizure detection accuracy with very short detection latency. Subsequently, we propose two novel methods for robust detection of epileptic seizures where the main question addressed is: Can we identify the seizure pattern(s) hidden in the contaminated EEG data? We first present a novel feature learning algorithm based on L1-penalized robust regression. This algorithm extracts the most distinguishable EEG spectral features pertinent to epileptic seizures. We then propose a deep learning method that achieves a better robust performance under real-life conditions. This method uses long-short-term memory recurrent networks to exploit the temporal dependencies in the EEG data and accurately recognize the seizure patterns. Both methods are proven to maintain robust performance in the presence of common signal contaminants and ambient noise. The thesis then addresses the seizure prediction problem using intracranial EEG (iEEG) data. A novel architecture of multi-scale convolutional neural networks is proposed to learn the discriminative pre-seizure iEEG features that could potentially help predict impending seizures. Experiments on clinical data show that this method achieves high seizure prediction sensitivity and maintains reliable performance against inter- and intra-patient variations.

description: This paper addresses the robustness of a network to sustain its connectivity and controllability against malicious attacks. This kind of network robustness is typically measured by the time-consuming attack simulation, which returns a sequence of values that record the remaining connectivity and controllability after a sequence of node- or edge-removal attacks. For improvement, this paper develops an efficient framework for network robustness prediction, the spatial pyramid pooling convolutional neural network (SPP-CNN). The new framework installs a spatial pyramid pooling layer between the convolutional and fully-connected layers, overcoming the common mismatch issue in the CNN-based prediction approaches and extending its generalizability. Extensive experiments are carried out by comparing SPP-CNN with three state-of-the-art robustness predictors, namely a CNN-based and two graph neural networks-based frameworks. Synthetic and real-world networks, both directed and undirected, are investigated. Experimental results demonstrate that the proposed SPP-CNN achieves better prediction performances and better generalizability to unknown datasets, with significantly lower time-consumption, than its counterparts.

Investigation  of the  Source  of Dual Fluorescence in  Quinoline-2-  carboxylic  acid through  Conformational Analysis

description: In  this  study  steady  state  absorption,  fluorescence  excitation  and  emission  spectra  of
quinoline-i-carboxylic  acid  have  been  examined  in  non-polar  and polar  solvents  and
computational  calculation  is  also performed to  achieve  the  goal  of  this  research  work  in
finding  the  origin  of  dual  fluorescence.  The  fluorescence  spectra  of  quinoline-Z.
carboxylic  acid  are  found  to  exhibit  dual  emission  in  polar solvent  (dioxatie  and DMSO)
at  a  shorter  and  at  longer  wctve  length  region  corresponding  to
I
Lb  and
I
La  state
respectively.  The  excitation  wavelength  dependence  of  the  emission  spectra  has  also  been
studied,  and  strong  dependence  was  observed  in  case  of  dioxane  and  Dlv!SO.  Closer
examination  of  the  absorption  (excitation)  spectra  of  the  sample  in  these  solvents
revealed  the  presence  of  two  different  absorptions  (excitations)  at  shorter  and  longer
wavelength  region  indicating  the  sources  of  the  two  emissive  states  to  be  in  the  ground
state.  The  3D  emission  spectra  of  the  sample  in  these  solvents  indicate  the
correspondence  between  the  observed  excitation  spectra  and  the  emission  spectra.
Stepwise  addition  of  solution  of  Zn  (II )  ion  i n  to  the  solution  o f  the  sample  changed  the
absorption  position f r o m  shorter  wavelength  to  the  longer  wavelength  region  indicating
the  presence  of  t wo  absorbing species  in  the ground state.  These  results  together  with  the
observation  of  t wo  energy  minima  i n  computational  calculations  of  the  PE S  of  quinoline-
2-carboxylic  acid,  indicated  the  presence  of  two  different  conformers  of  the  same
molecule  i n  the  ground  state  that  lead  to  two  close  l ying  excited  state;
1
Lb  and
I
La  and
thereby  results  in  the  dual  fluorescence  of  the  compound.  On  the  basis  of  the
experimental  and  theoretical  results,  it  is  suggested  that  the  existence  of  tw o  different
conformers  of  quinoline-i-carboxylic  acid  i n  the  ground  state,  which  are  at  equilibrium
are  the  cause  for  the  observed dual  fluorescence.

description: We characterize theoretically and experimentally the degradation of polarization entanglement in a fiber-optic entanglement distribution system where one of the optical fibers is exposed to the effects of polarization mode dispersion (PMD). We show gradual reduction of entanglement with increasing PMD and find that the highest PMD tolerance is achieved when the bandwidth of the pump used to generate the entangled photons in a $χ^{(3)}$ process is approximately half the bandwidth of the quantum channels.

description: Microsclerotia (MS) are considered one of the most promising propagules for use as active ingredients in biopesticides due to their tolerance to abiotic factors and ability to produce infective conidia for the control of pests. Therefore, the objective of this research was to establish the conditions required to induce the formation of microsclerotia in Metarhizium robertsii Mt004 and to study its development process, tolerance to abiotic factors and insecticidal activity of MS-derived conidia. M. robertsii started to form hyphal aggregates after 2 days and looked more compact after 8 days. MS were mature and pigmented after 20 days. The final yield was 2.0 × 103 MS/mL and MS size varied between 356.9 and 1348.4 μm. Ultrastructure analysis revealed that mature MS contained only a few live cells embedded in an extracellular matrix. Mature MS were more tolerance to UV-B radiation, heat and storage trials than conidia from Solid State Fermentation. MS-derived conidia were as virulent as conidia against Diatraea saccharalis larvae. These results showed that MS are promising propagules for the development of more persistent and efficient biopesticides for harsh environmental conditions. Our findings provide a baseline for production and a better understanding of microsclerotia development in M. robertsii strains.
A First and Second Law for Nonequilibrium Thermodynamics: Maximum Entropy Derivation of the Fluctuation-Dissipation Theorem and Entropy Production Functionals

description: A theory for non-equilibrium systems is derived from a maximum entropy approach similar in spirit to the equilibrium theory given by Gibbs. Requiring Hamilton's principle of stationary action to be satisfied on average during a trajectory, we add constraints on the transition probability distribution which lead to a path probability of the Onsager-Machlup form. Additional constraints derived from energy and momentum conservation laws then introduce heat exchange and external driving forces into the system, with Lagrange multipliers related to the temperature and pressure of an external thermostatic system. The result is a fully time-dependent, non-local description of a nonequilibrium ensemble. Detailed accounting of the energy exchange and the change in information entropy of the central system then provides a description of the entropy production which is not dependent on the specification or existence of a steady-state or on any definition of thermostatic variables for the central system. These results are connected to the literature by showing a method for path re-weighting, creation of arbitrary fluctuation theorems, and by providing a simple derivation of Jarzynski relations referencing a steady-state. In addition, we identify path free energy and entropy (caliber) functionals which generate a first law of nonequilibrium thermodynamics by relating changes in the driving forces to changes in path averages. Analogous to the Gibbs relations, the variations in the path averages yield fluctuation-dissipation theorems. The thermodynamic entropy production can also be stated in terms of the caliber functional, resulting in a simple proof of our microscopic form for the Clausius statement. We find that the maximum entropy route provides a clear derivation of the path free energy functional, path-integral, Langevin, Brownian, and Fokker-Planck statements of nonequilibrium processes.
