High density human neutrophils produce a transferable factor that delays apoptosis
Creators: name: Ahmad, Sharon Ameena
Publisher: name: University of British Columbia
Year: 2009

description: Pilot experiments performed in this laboratory showed that there was a delay in neutrophil apoptosis in culture at high cell densities. Increasing cell density resulted in a logarithmic decline in the percentage of apoptotic neutrophils when cells were cultured at densities between 3xl0³ and l xl0⁷ cells/cm² (p<0.003, n=3). Investigation of this phenomenon resulted in the detection of a transferable factor produced by high density neutrophils, that was able to delay apoptosis in low density neutrophils when co-cultured. Various soluble mediators were studied to determine the identity of the transferable factor. ELISA assays performed on high density neutrophil-conditioned medium indicated that, of the cytokines tested (GM-CSF, IL-8, IL-6, IL-1β, and TNF-α), neutrophils were producing only IL-8 in significant quantities. Monoclonal neutralizing antibodies to the cytokines G M - CSF, G-CSF, and IL-8 added to neutrophil cultures were not successful in inhibiting the high density delay in neutrophil apoptosis, nor was the platelet-activating factor inhibitor, WEB 2170. The role of cell-cell contact and adhesion molecules CD18, CD11b, CD11a, and L - selectin, were also investigated as high neutrophil density suggests increased cell-cell contact. Blocking antibodies to these cell adhesion molecules added to neutrophil cultures had no effect on the density-dependent delay in neutrophil apoptosis. The CD18/ CD11b upregulator, fMLP, added at either high or low concentrations, also had no effect on neutrophil apoptosis at any density. These data show that there is a delay in neutrophil apoptosis at high cell densities, potentially involving a transferable factor produced by the high density neutrophils, and unlikely to involve intercellular interaction of CD8, CD11b, CD11a, or L-selectin. These findings have important implications for the study of neutrophils both in vitro and in vivo.

description: Energy consumption is one of the most critical protocol properties in a wireless sensor network. Therefore, a precise energy model is required for the evaluation of protocols. In addition to evaluation, an energy model can also be used for on-line energy accounting. After processing user queries, nodes aware of the energy model can send an energy bill towards the network's sink. This allows the user to adjust future queries to be more energy efficient. The contribution of this paper is twofold: First, a theoretical energy model based on simple finite automata is presented. This model can be used for on-line accounting, simulation and generation of a-priori knowledge. Second, the proposed theoretical model is backed up by practical measurements using a new measurement device called SNMD that also offers management functions for sensor-net testbeds. Therewith, output of the theoretical model can be compared to and justified by real-world measurements.

Publisher: name: University of British Columbia

description: Cardiac rehabilitation, an important component of the treatment for coronary artery disease, is provided by a multidisciplinary team in the Healthy Heart Program. The purpose of this study was to evaluate the impact of the Healthy Heart Program on maintenance of healthy lifestyle behaviors and hospital readmission rates, to increase our understanding of the effectiveness of the program, and to make recommendations for improvement of the program. The study began with a retrospective chart review to select study participants, and from which data was collected on demographics and rate of achievement of healthy lifestyle goals during the program. Analysis of the data revealed that the majority of participants were able to successfully achieve their goals during the program. A telephone interview was then conducted with graduates of the program to determine if healthy lifestyle behaviors were maintained and the rate of and reasons for visits to hospital. Analysis of the data revealed that sustained behavior change did occur for at least six months after exiting the program. Analysis of the data also revealed that few Healthy Heart Program participants required visits to the emergency department or admission to hospital for cardiac reasons. Recommendations for improvement to this program include improved stress management, diet management and smoking cessation strategies. As well, strategies to provide more individualized programs for modification of cardiac risk factors would be useful. Ongoing evaluation on cardiac rehabilitation programs for maintenance of healthy lifestyle behaviors is also necessary.

description: Rotation of MO6 (M = transition metal) octahedra is a key determinant of the physical properties of perovskite materials. Therefore, tuning physical properties, one of the most important goals in condensed matter research, may be accomplished by controlling octahedral rotation (OR). In this study, it is demonstrated that OR can be driven by an electric field in Sr$_2$RuO$_4$. Rotated octahedra in the surface layer of Sr$_2$RuO$_4$ are restored to the unrotated bulk structure upon dosing the surface with K. Theoretical investigation shows that OR in Sr$_2$RuO$_4$ originates from the surface electric field, which can be tuned via the screening effect of the overlaid K layer. This work establishes not only that variation in the OR angle can be induced by an electric field, but also provides a way to control OR, which is an important step towards in situ control of the physical properties of perovskite oxides.
Causality in gravitational theories with second order equations of motion

description: This paper considers diffeomorphism invariant theories of gravity coupled to matter, with second order equations of motion. This includes Einstein-Maxwell and Einstein-scalar field theory with (after field redefinitions) the most general parity-symmetric four-derivative effective field theory corrections. A gauge-invariant approach is used to study the characteristics associated to the physical degrees of freedom in an arbitrary background solution. The symmetries of the principal symbol arising from diffeomorphism invariance and the action principle are determined. For gravity coupled to a single scalar field (i.e. a Horndeski theory) it is shown that causality is governed by a characteristic polynomial of degree $6$ which factorises into a product of quadratic and quartic polynomials. The former is defined in terms of an "effective metric" and is associated with a "purely gravitational" polarisation, whereas the latter generically involves a mixture of gravitational and scalar field polarisations. The "fastest" degrees of freedom are associated with the quartic polynomial, which defines a surface analogous to the Fresnel surface in crystal optics. In contrast with optics, this surface is generically non-singular except on certain surfaces in spacetime. It is shown that a Killing horizon is an example of such a surface. It is also shown that a Killing horizon satisfies the zeroth law of black hole mechanics. The characteristic polynomial defines a cone in the cotangent space and a dual cone in the tangent space. The latter is used to define basic notions of causality and to provide a definition of a dynamical black hole in these theories.

description: The holotype specimen of the non-pterodactyloid pterosaur Eudimorphodon rosenfeldi from the Late Triassic (Norian) of NE Italy is described in detail and compared to the other specimens referred in literature to the genus Eudimorphodon. It is considered conspecific with the specimen MPUM 6009 from the Norian of NW Italy, previously attributed to Eudimorphodon ranzii. A new genus, Carniadactylus, is proposed for the two specimens based on the apomorphic shape of the "coronoid" process, coracoid and pteroid, wing phalanx proportions and the several anatomical differences with E. ranzii and "Eudimorphodon" cromptonellus. No definitive evidence of a juvenile stage occurs in the two specimens. A phylogenetic analysis using parsimony shows that Carniadactylus is nested inside the Campylognathoididae and is the sister-group of Caviramus schesaplanensis + "Raeticodactylus" filisurensis. The systematics of specimens referred in the literature to Eudimorphodon is reviewed.

description: The following ammonoid and nautiloid taxa are described for the first time from the Upper Triassic succession (Ekrasar Formation, Shemshak Group) of northern Alborz, Iran: Arcestes sp., Arcestes (Pararcestes?) sp., Thisbites cf. agricolae Mojsisovics, Stikinoceras cf. kerri Mc Learn, Giesbachites sp., Griesbachites cf. pseudomedleyanus Diener, Griesbachites cf. himalayanus Wang & He, and Proclydonautilus? sp. Palaeobiogeographically, the studied ammonoids are Tethyan in character, and stratigraphically attributed to the lower Lower Norian (Guembelites jandianus Zone, possibly also Malayites paulckei Zone). The biostratigraphic data of this study demonstrate the diachronous base of the Shemshak Group: it is older in the northern Alborz (lower Lower Norian), but younger in Central Iran and probably also in the southern Alborz (Middle Norian).

description: Detailed control over the motion of colloidal particles is relevant in many applications in colloidal science such as lab-on-a-chip devices. Here, we use an external magnetic field to assemble paramagnetic colloidal spheres into colloidal rods of several lengths. The rods reside above a square magnetic pattern and are transported via modulation of the direction of the external magnetic field. The rods behave like bipeds walking above the pattern. Depending on their length, the bipeds perform topologically distinct classes of protected walks above the pattern. We demonstrate that it is possible to design parallel polydirectional modulation loops of the external field that command up to six classes of bipeds to walk on distinct predesigned paths. We use such parallel polydirectional loops to induce the collision of reactant bipeds, their polymerization addition reaction to larger bipeds, the separation of product bipeds from the educts, the sorting of different product bipeds, and also the parallel writing of a word consisting of several different letters.
DISCOSIPHONELLA MINIMA SENOWBARI-DARYAN & LINK AND SOLENOLMIA? PARVA N. SP. ("SPHINCTOZOA", PORIFERA) FROM THE UPPER TRIASSIC (NORIAN) OF THE SOUTHERN APPENNINES (NORTHERN CALABRIA/ITALY)

description: Two hypercalcified sphinctozoan sponges are described from several localities of dolomitic Norian reefs of northern Calabria (southern Italy). Solenolmia? parva n. sp. occurs as an extremely abundant, albeit local, component in peculiar bioconstructions dominated by serpulids and microbialitic crusts. Discosiphonella minima Senowbari-Daryan & Link, previously recognized only in the type locality of Turkey, has been now found also as a minor component in association with other typical "Dachstein" reef biota, such as corals, sponges, microbial crusts and fragments of "microproblematica". Solenolmia? parva assemblage represents the primary framebuilder of small build-ups which developed on the margins of restricted intraplatform basins. The Discosiphonella minima assemblages were found as resedimented blocks along the slope of intraplatform anoxic basins. The distribution of the different reefal assemblages of Northern Calabria can be related to the paleogeographic position of northern Calabria with respect to the evolution of Triassic crustal extension in western Mediterranean.

description: The fuel ethanol industry is poised to adopt a wide range of technologies that would reduce costs at every stage of the production process. Improved enzymes and fermenter designs can reduce the time needed to convert corn to ethanol and lower capital costs. Membrane filtration can allow the recovery of high-value coproducts such as lactic acid. Adoption of these and other innovations in the next 5 years is expected in new ethanol plants constructed to cope with new demand resulting from Clean Air Act stipulations for cleaner burning fuel. Biomass (agricultural residues, municipal and yard waste, energy crops like switchgrass) can also be converted to ethanol, although commercial-scale ventures are limited by current technology. While biomass requires more handling and sorting before conversion, those costs may be offset by the abundance of biomass relative to corn.

description: This analysis updates two previous analyses that evaluated the exposure-response relationships for lung cancer and mesothelioma in chrysotile-exposed cohorts. We reviewed recently published studies, as well as updated information from previous studies. Based on the 16 studies considered for chrysotile (<10% amphibole), we identified the “no-observed adverse effect level” (NOAEL) for lung cancer and/or mesothelioma; it should be noted that smoking or previous or concurrent occupational exposure to amphiboles (if it existed) was not controlled for. NOAEL values ranged from 2.3–<11.5 f/cc-years to 1600–3200 f/cc-years for lung cancer and from 100–<400 f/cc-years to 800–1599 f/cc-years for mesothelioma. The range of best-estimate NOAELs was estimated to be 97–175 f/cc-years for lung cancer and 250–379 f/cc-years for mesothelioma. None of the six cohorts of cement or friction product manufacturing workers exhibited an increased risk at any exposure level, while all but one of the six studies of textile workers reported an increased risk at one or more exposure levels. This is likely because friction and cement workers were exposed to much shorter chrysotile fibers. Only eight cases of peritoneal mesothelioma were reported in all studies on predominantly chrysotile-exposed cohorts combined. This analysis also proposed best-estimate amosite and crocidolite NOAELs for mesothelioma derived by the application of relative potency estimates to the best-estimate chrysotile NOAELs for mesothelioma and validated by epidemiology studies with exposure-response information. The best-estimate amosite and crocidolite NOAELs for mesothelioma were 2–5 f/cc-years and 0.6–1 f/cc-years, respectively. The rate of peritoneal mesothelioma in amosite- and crocidolite-exposed cohorts was between approximately 70- to 100-fold and several-hundred-fold higher than in chrysotile-exposed cohorts, respectively. These findings will help characterize potential worker and consumer health risks associated with historical and current chrysotile, amosite, and crocidolite exposures.

description: The Toarcian/Aalenian Global Stratotype Section and Point (GSSP) have been recently placed in the Fuentelsaz section, northeastern Spain. This paper is part of a long-term project that attempts to describe for the first time the fossil ostracod assemblages present in the Toarcian-Aalenian boundary GSSP, and to assess their palaeobiogeographical significance. The study of the Late Toarcian-Early Aalenian Turmiel and Casinos formations at the Fuentelsaz section has produced a detailed stratigraphy and a large collection of stratigraphically constrained ostracod faunas. Twenty benthic ostracod species have been identified and for the first time described in Spain. Higher part of the Mactra Subzone, Late Toarcian, have yielded abundant ostracod faunas, including mostly species of the genera Praeschuleridea, Cytherelloidea and Kinkelinella; fossiliferous marls of the Late Toarcian and part of the Early Aalenian and poorly fossiliferous marls at the beginning of the Opalinum Zone are dominated by Praeschuleridea and Cytherelloidea. The boundary between the Toarcian and Aalenian is not characterized by any radical change in the ostracod faunal composition. The Fuentelsaz sequence exhibits ostracod assemblages comparable to those recorded in western Europe, with many of their species having similar stratigraphical distributions.

description: We report on a pure $^{181}$Ta-nuclear quadrupole resonance (NQR) measurement of PbTaSe$_2$ at zero magnetic field, which has the advantage of directly probing the intrinsic superconducting phase and electronic states of the TaSe$_2$ layer. We observed the $^{181}$Ta-NQR spectrum of the intrinsic structure with space group $P6$-$m2$, which agrees well with density functional theory (DFT) calculations. The nuclear spin relaxation rate ($1/T_1$) shows an exponential decrease well below $T_{\rm_c}$, indicating that the superconducting state is fully gapped in the framework of Bardeen-Cooper-Schrieffer (BCS) theory. The gap size obtained by $^{181}$Ta-NQR was smaller than the value in previous reports, which may imply that the Fermi surfaces composed of Ta-5$d$ orbitals, where the average pairing interactions are expected to be weaker than in BCS model, are primarily probed. The temperature dependence of $1/T_1$ below $T_{\rm_c}$ can be reproduced well by the superposition of quadrupole and magnetic relaxation mechanisms, together with the distribution of superconducting gap size inherent to multiple Fermi surfaces theoretically proposed in PbTaSe$_2$.

description: Since the '60s geologists discussed if the Tuscan Nappe includes the Macigno, the Mt. Modino Sandstone and the olistostromes interposed between these two clastic wedges or instead the foredeep deposits of the Tuscan Nappe is the Macigno and, therefore, the Mt. Modino Sandstone sedimented in a distinct basin and belongs to a different tectonic unit. One of the main difficulties to unravel the Macigno-Mt. Modino Sandstone relationships is the absence of continuous biostratigraphic records, helpful to date these formations and the underlying units. To fill this gap, a quantitative biostratigraphical analysis of calcareous nannofossils was performed on a large number of smear slides. The results confirm the stratigraphic continuity between the Tuscan Shale and the Macigno, and prove the stratigraphic continuity between the Fiumalbo Shale, the Marmoreto Marl and the Mt. Modino Sandstone (Mt. Modino Unit auctt.), supporting the tectonic superposition of the Mt. Modino Unit onto the Tuscan Nappe. In fact, the upper portion of the Tuscan Nappe ranges from the Late Eocene (MNP19/20) to the lower Miocene (MNN1c) and the Tuscan Shale-Macigno boundary lies within the upper Rupelian-Chattian (MNP24-MNP25a), whilst the sampled part of the Mt. Modino Unit spans in age the middle Eocene-lower Miocene (MNP15-MNN1c), and the Fiumalbo Shale-Marmoreto Marl and Marmoreto Marl-Mt. Modino Sandstone boundaries lie within the Rupelian (MNP23) and the uppermost Chattian (MNP25b-MNN1a).

description: The influence of cobalt doping in SnO2 crystal lattice tailored the optical, structural, and surface properties of SnO2. Co2+ was successfully doped in SnO2 (Co-SnO2) via green synthesis using Tradescantia spathacea aqueous leaf extract. Powder X-ray diffraction patterns of the synthesized nanoparticles showed a rutile structure with no impurities. As Co-doping was increased, the average crystallite size increased from 13.25 nm to 32.32 nm and BET results showed reduced surface area. The presence oforganic compounds of the aqueous leaf extract was confirmed by Fourier-transform infrared spectroscopy. UV-visible diffuse reflectance spectroscopy showed a red shift suggesting a band gap reduction with Co-doping. The photoluminescence study showed a peak quenching with the increase in Co-doping. Spherical and smaller particles were observed by scanning electron microscopy. The density of states was proposed using X-ray photoelectron spectroscopy and UV-visible diffuse reflectancespectroscopy data. A novel antioxidant study of SnO2 and Co-SnO2 nanoparticles was done under visible light irradiation using 2,2-diphenyl-1-picrylhydrazyl free radicals and was compared to conventional antioxidant method in the dark. Photocatalytic 4-nitrophenol conversion was also conducted in the dark and under visible light irradiation. The enhancement in the photoantioxidant activities and photocatalytic conversion of 4-nitrophenol to 4-itrophenolate using SnO2 and Co-SnO2 was observed under visible light irradiation.

description: If neutral Higgs bosons will be discovered at the CERN Large Hadron Collider (LHC) then an important subsequent issue will be the investigation of their CP nature. Higgs boson decays into tau lepton pairs are particularly suited in this respect. Analyzing the three charged pion decay modes of the tau leptons and taking expected measurement uncertainties at the LHC into account, we show that the CP properties of a Higgs boson can be pinned down with appropriately chosen observables, provided that sufficiently large event numbers will eventually be available.

description: Due to its proximity to Earth, Jupiter of the Solar System serves as a unique case study for gas-giant exoplanets. In the current study, we perform fits of ab initio, reflective, semi-infinite, homogeneous model atmospheres to 61 phase curves from 0.40 to 1.00 $μ$m, obtained from the Cassini spacecraft, within a Bayesian framework. We reproduce the previous finding that atmospheric models using classic reflection laws (Lambertian, Rayleigh, single Henyey-Greenstein) provide poor fits to the data. Using the double Henyey-Greenstein reflection law, we extract posterior distributions of the single-scattering albedo and scattering asymmetry factors and tabulate their median values and uncertainties. We infer that the aerosols in the Jovian atmosphere are large, irregular, polydisperse particles that produce strong forward scattering together with a narrow backscattering lobe. The near-unity values of the single-scattering albedos imply that multiple scattering of radiation is an important effect. We speculate that the observed narrow backscattering lobe is caused by coherent backscattering of radiation, which is usually associated with Solar System bodies with solid surfaces and regolith. Our findings demonstrate that precise, multi-wavelength phase curves encode valuable information on the fundamental properties of cloud/haze particles. The method described in this Letter enables single-scattering albedos and scattering asymmetry factors to be retrieved from James Webb Space Telescope phase curves of exoplanets.

description: Since 1991, the Caverna Generosa was subject of numerous digging campaigns, principally in two areas called "Sala Terminale" and "Cunicolo 13-15". Dating of the first 6 stratigrafical levels of the 13 investigated in the "Sala Terminale" gave an age between 50.000 and 38.000 years BP (14C non calibrated dating). In the area of the "Cunicolo 13-15", between meters 13 and 15 from the entrance, seven stratigrafical levels were excavated, and bones coming from layers from II to V were dated between 37.000 and 31.000 years BP ago (14C non calibrated dating). Microvertebrates remains are used to infer paleoenvironmental and paleoclimatic information. The microfaunal assemblages of "Sala Terminale" testifies for a climatic improvement, during the period between over 50.000 y BP and 40.000 y BP: from a cold climate and an environment characterised by open vegetation to a wooded areas and milder temperature. This climatic improvement is also recorded in the lower level of "Cunicolo 13-15", probably subsequent to the top of the "Sala Terminale". Then, microfaunal associations became typical of cold climate. This climatic worsening had its maximum at the base of lev. Cun 0, during the last Pleniglacial. Therefore, the sediments of "Caverna Generosa" probably testify the climatic and faunal changes of the period between isotopic stage 4 and 1.

description: Wave effects can be important for the gravitational lensing of gravitational waves. In such a case, wave optics must be used in stead of geometric optics. We consider a plane wave entering a lens object and solve numerically the wave equation for three lens models: the uniform density sphere, the singular isothermal sphere, and the Hernquist model. By comparing our numerical solutions with the analytical solutions under the thin lens approximation, we evaluate the error of this approximation. The results show that the relative error of the thin lens approximation is small if the geometrical thickness of the lens is much smaller than the distance between the lens and the observer.

description: Building footprint extraction (BFE) from multi-sensor data such as optical images and light detection and ranging (LiDAR) point clouds is widely used in various fields of remote sensing applications. However, it is still challenging research topic due to relatively inefficient building extraction techniques from variety of complex scenes in multi-sensor data. In this study, we develop and evaluate a deep competition network (DCN) that fuses very high spatial resolution optical remote sensing images with LiDAR data for robust BFE. DCN is a deep superpixelwise convolutional encoder-decoder architecture using the encoder vector quantization with classified structure. DCN consists of five encoding-decoding blocks with convolutional weights for robust binary representation (superpixel) learning. DCN is trained and tested in a big multi-sensor dataset obtained from the state of Indiana in the United States with multiple building scenes. Comparison results of the accuracy assessment showed that DCN has competitive BFE performance in comparison with other deep semantic binary segmentation architectures. Therefore, we conclude that the proposed model is a suitable solution to the robust BFE from big multi-sensor data.

LATE TRIASSIC (EARLY-MIDDLE CARNIAN) CRUROTARSAN TRACKS FROM THE VAL SABBIA SANDSTONE (EASTERN LOMBARDY, BRESCIAN PREALPS, NORTHERN ITALY)

description: A new Late Triassic tetrapod tracksite was discovered north of the Zone village, on the north-eastern side of the Iseo Lake (Southern Alps, Brescia, Lombardy). The tracks are preserved on two distinct bedding planes, belonging to the lower/middle Carnian Val Sabbia Sandstone. The ichnoassemblage is composed of about seventy footprints, organized in six quadrupedal trackways exhibiting both wide and narrow gauge. All the trackways can be attributed to a crurotarsan archosaur trackmaker and at least three of them could be assigned with confidence to the ichnogenus Brachychirotherium Beurlen 1950. If we exclude a dubious Brachychirotherium specimen track from Mt. Pelmetto (Dolomites), the Zone material represents the first well documented report of this ichnogenus from the Upper Triassic of Northern Italy. The footprints have been analyzed both with traditional methods, and with 3D technologies, such as the terrestrial laser scanner. The ichnoassemblage, although not exceptionally preserved, adds new important data for the stratigraphic distribution of crurotarsan tracks in the Triassic of Southern Alps.

description: This paper deals with the regional stratigraphy around the Alps-Apennines junction during late Eocene-Miocene. The basin-fill architecture and its relation to changes in structural style were deciphered through the integration of subsurface and outcrop data on the basis of seismic- and sequence-stratigraphy principles, respectively.
During late Eocene-Oligocene, the study area hosted a mosaic of partially interconnected sub-basins, and the Torino Hill area marked the junction towards the western apex of the Southern Alps foredeep (Gonfolite Basin). Since the latest Oligocene, the uplift of the north-verging Monferrato arc provided the separation from the adjacent Gonfolite Basin and the Tertiary Piedmont Basin behaved as a larger and more regularly subsiding thrust-top basin.
The upper Eocene-Miocene successions record a long-term, major transgressive-regressive cycle, consisting of seven large-scale unconformity-bounded stratigraphic units, whose stacking pattern was controlled by changes in the rate of tectonic subsidence and whose boundaries were generated by basin-modification phases. During the Oligocene-lower Miocene deepening-upward sequence set, the marginal marine systems show a marked diachronism associated with  the SW-ward change of coastal onlap, punctuated by drowning-platform unconformities generated in relation to basinward tilting and high-angle synsedimentary faults.  The maximum transgression coincides with the late Burdigalian tectonic space creation phase, when a basinwide, highly efficient turbidite system was deposited. The middle-upper Miocene progradation, punctuated by forced regression pulses, was driven by the inversion and uplift of the southern basin margin, so that a northward shift and progressive narrowing of the turbidite depocentre occurred.

description: We present the physical model for the entropy source of a quantum random number generator chip based on the quantum fluctuations of the photon number emitted by light-emitting diodes. This model, combined with a characterization of the chip, estimates a quantum min-entropy of over 0.98 per bit without post-processing. Finally, we show with our model that the performances in terms of security are robust against fluctuations over time.
Distribution of Gamma-ray Burst Ejecta Energy with Lorentz Factor

description: The early X-ray afterglow for a significant number of gamma-ray bursts detected by the Swift satellite is observed to have a phase of very slow flux decline with time ($F_ν\propto t^{-α}$ with $0.2 \lesssim α\lesssim 0.8$) for $10^{2.5} s \lesssim t \lesssim 10^4$ s, while the subsequent decline is the usual $1 \lesssim α_3 \lesssim 1.5$ behavior, that was seen in the pre-Swift era. We show that this behavior is a natural consequence of a small spread in the Lorentz factor of the ejecta, by a factor of $\sim 2-4$, where the slower ejecta gradually catch-up with the shocked external medium, thus increasing the energy of forward shock and delaying its deceleration. The end of the ``shallow'' flux decay stage marks the beginning of the Blandford-McKee self similar external shock evolution. This suggests that most of the energy in the relativistic outflow is in material with a Lorentz factor of $\sim 30-50$.

On (non-)monotonicity and phase diagram of finitary random interlacement

description: In this paper, we study the evolution of a Finitary Random Interlacement (FRI) with respect to the expected length of each fiber. In contrast to the previously proved phase transition between sufficiently large and small fiber length, we show that for $d=3,4$, FRI is NOT stochastically monotone as fiber length increasing. At the same time, numerical evidences still strongly support the existence of a unique and sharp phase transition on the existence of a unique infinite cluster, while the critical value for phase transition is estimated to be an inversely proportional function with respect to the system intensity.

description: We consider a cusped Wilson line with J insertions of scalar fields in N=4 SYM and prove that in a certain limit the Feynman graphs are integrable to all loop orders. We identify the integrable system as a quantum fishchain with open boundary conditions. The existence of the boundary degrees of freedom results in the boundary reflection operator acting non-trivially on the physical space. We derive the Baxter equation for Q-functions and provide the quantisation condition for the spectrum. This allows us to find the non-perturbative spectrum numerically.

description: Electric deflections of niobium clusters in molecular beams show that they have permanent electric dipole moments at cryogenic temperatures but not higher temperatures, indicating that they are ferroelectric. Detailed analysis shows that the deflections cannot be explained in terms of a rotating classical dipole, as claimed by Anderson et al. The shapes of the deflected beam profiles and their field and temperature dependences indicates that the clusters can exist in two states, one with a dipole and the other without. Cluster with dipoles occupy lower energy states. Excitations from the lower states to the higher states can be induced by low fluence laser excitation. This causes the dipole to vanish.

description: A contract is an agreement between a buyer and a seller that specifies terms for future delivery of and payment for a product, asset, or service. Contracting enables farmers to reduce income uncertainty by assuring prices and outlets for their crops and livestock before the products are actually delivered. This report describes some of the contracting alternatives available to farmers, the factors to be considered in choosing among the different types of contracts, and the major advantages and disadvantages of each alternative. For example, the contracts most widely used by farmers are with local buyers. Such contracts assure farmers' outlets and set conditions for delivery. Some farmers use the highly standardized contracts traded on futures exchanges to temporarily set approximate prices for their products or inputs, pending actual sales to or purchases from local merchants or processors. Commodity options contracts, which are also highly standardized and traded on exchanges, can be used to set approximate lower or upper bounds on prices for commodities to be sold or bought later. The farmer's choice of contracts depends on the commodities produced or used as inputs, and the farmer's financial situation and risk preferences.

description: We present results for the three-loop universal anomalous dimension of Wilson twist-2 operators in the N=4 Supersymmetric Yang-Mills theory. These expressions are obtained by extracting the most complicated contributions from the three-loop anomalous dimensions in QCD. This result is in an agreement with the hypothesis of the integrability of N=4 Supersymmetric Yang-Mills theory in the context of AdS/CFT-correspondence.
