description: We investigate the linear polarization in the light of extrasolar planetary systems that may arise as a result of an occultation of the star by a transiting planet. Such an occultation breaks any spherical symmetry over the projected stellar disk and thus results in a non-vanishing linear polarization. This polarization will furthermore vary as the occultation progresses. We present both analytical and numerical results for the occultation of G-K-M-T dwarf stars by planets with sizes ranging from the one of Earth to two times the size of Jupiter. We find that the occultation polarization may result in an observable signal and provide additional means to characterize various parameters of the system. A particularly interesting result is that, for the later spectral types (i.e., smaller stellar radii), this polarization signature may be observable even for Earth-like planets. This suggests polarization as a possible tool to detect such planets. Departs from symmetry around mid-transit in the time dependence of the polarization signature may provide an estimate of the orbital eccentricity.

description: The merging black-hole (BH) binaries GW190412, GW190814 and GW190521 from the third LIGO/VIRGO observing run exhibit some extraordinary properties, including highly asymmetric masses, significant spin, and component mass in the "mass gap". These features can be explained if one or both components of the binary are the remnants of previous mergers. In this paper, we explore hierarchical mergers in multiple stellar systems, taking into account the natal kick and mass loss due to the supernova explosion (SN) on each component, as well as the merger kick received by the merger remnant. The binaries that have survived the SNe and kicks generally have too wide orbital separations to merge by themselves, but can merge with the aid of an external companion that gives rise to Lidov-Kozai oscillations. The BH binaries that consist of second-generation BHs can also be assembled in dense star clusters through binary interactions. We characterize the parameter space of these BH binaries by merger fractions in an analytical approach. Combining the distributions of the survived binaries, we further constrain the parameters of the external companion, using the analytically formulated tertiary perturbation strength. We find that to produce the three LIGO/VIRGO O3 events, the external companions must be at least a few hundreds $M_\odot$, and fall in the intermediate-mass BH and supermassive BH range. We suggest that GW190412, GW190814 and GW190521 could all be produced via hierarchical mergers in multiples, likely in a nuclear star cluster, with the final merger induced by a massive BH.

description: The increasing popularity of essential oils for skincare has led to investigation of their biological effects in human skin cells. In this study, we investigated the biological activities of three commercially available essential oils, i.e. rosemary oil, wild orange oil, and a blend (commercial name: Deep Blue) composed of oils from wintergreen, camphor, peppermint, blue tansy, German chamomile, Helichrysum, and Osmanthus, in a pre-inflamed human dermal fibroblast culture model, simulating chronic inflammation. The impact of essential oils on proteins associated with inflammation and tissue remodeling and on the genome-wide expression of 21,224 genes was investigated. The three essential oils diversely modulated global gene expression. Ingenuity Pathway Analysis showed that the oils affected numerous critical genes and signaling pathways. Specifically, rosemary oil influenced processes involved in cancer signaling and metabolism; orange oil affected processes related to cancer signaling, immunomodulation, and metabolism; the blend influenced inflammation, immunomodulation, and wound healing. These findings are largely consistent with the existing literature, supporting the beneficial biological activities of these essential oils. Our study provides the first evidence indicating how these essential oils affect genome-wide gene expression in human skin cells and establishes a basis for further research into their biological mechanisms of action.

description: We study the damage process of fiber bundles in a wedge-shape geometry which ensures a constant strain gradient. To obtain the wedge geometry we consider the three-point bending of a bar, which is modelled as two rigid blocks glued together by a thin elastic interface. The interface is discretized by parallel fibers with random failure thresholds, which get elongated when the bar is bent. Analyzing the progressive damage of the system we show that the strain gradient results in a rich spectrum of novel behavior of fiber bundles. We find that for weak disorder an interface crack is formed as a continuous region of failed fibers. Ahead the crack a process zone develops which proved to shrink with increasing deformation making the crack tip sharper as the crack advances. For strong disorder, failure of the system occurs as a spatially random sequence of breakings. Damage of the fiber bundle proceeds in bursts whose size distribution shows a power law behavior with a crossover from an exponent 2.5 to 2.0 as the disorder is weakened. The size of the largest burst increases as a power law of the strength of disorder with an exponent 2/3 and saturates for strongly disordered bundles.

description: An interpretation to the physics of stable geodesics of massive particles in black hole backgrounds has been recently proposed in the context of the AdS/CFT correspondence. It was argued that the existence of stable orbits indicates that the dual state does not thermalize on a thermal time scale and the bulk excitations can be interpreted as metastable states in the dual field theory. Here we study motion of massive particles in the background of the D-dimensional asymptotically anti-de Sitter (AdS) black holes in the Einstein-Lovelock theory. We show that, unlike the asymptotically flat case, for any kind of higher curvature Lovelock corrections there appear a stable circular orbit at a distance from the black hole. We find the general analytical expressions for the frequencies of distant circular orbits and radial oscillation frequencies. We show that the corresponding correction has the same power as in the Schwarzschild-AdS case, implying a universal scaling with the temperature for any Lovelock theory.

description: A two-fluid model is proposed to describe the transport properties of granular superconductors. Using the resistively shunted junction model and some aspects of the two-level system theory, a statistical model is developed which takes into account the ratio between the number of normal and superconducting electrons carrying the applied current. The theoretical model reveals excellent agreement when compared to transport properties of four high-Tc superconductors. The results suggest that the two-fluid model is independent of the sample composition, critical temperature and whether the superconducting compound is electron or hole-doped.

description: The EU enlargement revives the debate around the participation to the EMU. The accession to a monetary union can affect trade through several channels. In this paper we study the link between the membership to a monetary union and informal barriers to trade. The question we ask is whether the participation to the Euro Area reduces the impact of informal barriers on new members' agricultural trade. We base our analysis on Greek imports of agricultural products from partners in the Euro area and third countries between 1996 and 2005. A first result we find is that the country's accession to the Euro zone has reduced the effect of information flows on its imports of agricultural products from EMU partners. Secondly, institutional aspects have become a less important determinant of Greek imports from all countries. After 2001 non-EMU suppliers are viewed by Greek partners as more homogeneous in terms of institutions' quality.

Year: 1978
Subjects: subject: Transportation Engineering

description: The objective of this report was to develop a procedure for the collection and use of traffic conflict data. Data were collected at five intersections to determine characteristics of conflicts. Observer reliability was found to be excellent. Traffic volumes accounted for only about 30 percent of the variation in numbers of conflicts. At one intersection, repeatability of conflict numbers, rates, and types was found to be very good. A total of 6,535 conflicts and 2,957 benign weaves were observed at the test sites.  Based on the data, recommendations were made for collecting data during three peak hours at each site. Revised conflict data sheets were developed for signalized and nonsignalized intersections. The conflict diagram is illustrated and recommended for use. Collection of conflict data is recommended during inspections of suspected hazardous locations.

description: This paper attempts to generalize the results, on both the local and the national level, of graziers on 1.7m. acres of New England following planned investment patterns developed from farm surveys. This area, at present unimproved, is assumed capable of establishment under improved pastures over a period of ten years. If all the investment capital required over and above the additional revenue generated by the improvement (assuming no change from present prices) were supplied as loans to landholders, the advances required would range at their maximum between £8 and £10 per acre, or £l3m. to £17m. in aggregate, according to the pattern of improvement adopted. Under these conditions farmers would receive approximately 10 per cent return on investment, but if debts were to be amortized as soon as possible, disposable net revenue would not increase until about the eighteenth year. Many may consider that such a result provides insufficient inducement to invest, but in the long run unimproved properties are expected to fare worst in any continued cost-price squeeze. Net export earnings from such a scheme would be £50m. to £80m. over the twenty years considered, while turnover on the farms considered would increase by some £lOOm. Investment in such development could provide superior benefits to other national schemes, and such peripheral development may avoid the need for some shifts of population while making greater use of existing communications and utilities.

description: Recent Chandra and XMM-{\it Newton} observations reported evidence of two X-ray filaments G359.88-0.08 (SgrA-E) and G359.54+0.18 (the ripple filament) near the Galactic center. The X-ray emission from these filaments has a nonthermal spectrum and coincides with synchrotron emitting radio sources. Here, we report the detection of a new X-ray feature coincident with a radio filament G359.90-0.06 (SgrA-F) and show more detailed VLA, Chandra and BIMA observations of the radio and X-ray filaments. In particular, we show that radio emission from the nonthermal filaments G359.90-0.06 (SgrA-F) and G359.54+0.18 (the ripple) has a steep spectrum whereas G359.88-0.08 (SgrA-E) has a flat spectrum. The X-ray emission from both these sources could be due to synchrotron radiation. However, given that the 20 \kms molecular cloud, with its intense 1.2mm dust emission, lies in the vicinity of SgrA-F, it is possible that the X-rays could be produced by inverse Compton scattering of far-infrared photons from dust by the relativistic electrons responsible for the radio synchrotron emission. The production of X-ray emission from ICS allows an estimate of the magnetic field strength of ~0.08 mG within the nonthermal filament. This should be an important parameter for any models of the Galactic center nonthermal filaments.

description: In this paper we combine archival and proprietary XMM-Newton observations (about 5deg^2) that overlap with the Sloan Digital Sky Survey to explore the nature of the moderate-z X-ray population. We focus on X-ray sources with optically red colours (g-r>0.4), which we argue are important for understanding the origin of the X-ray background. Firstly, these systems constitute a significant fraction, about 2/3, of the z<1 X-ray population to the limit f(2-8keV)~2e-14cgs. Secondly, their luminosity function under evolution of the form ~(1+z)^3 suggests that they could be responsible for about 17 per cent of the diffuse X-ray background to z=1. Thirdly, their stacked X-ray spectrum in the range 1-8keV is consistent with a power-law distribution with Gamma~1.4 (without fitting intrinsic absorption), i.e. similar to the diffuse X-ray background. We find that the optically red X-ray population comprises a mixed bag of objects, both obscured (N_H>1e22 cm^{-2}) and unobscured (N_H<1e22 cm^{-2}), with a wide range of X-ray luminosities up L_X~1e44cgs. We argue that dilution of the AGN light by the host galaxy may play a role in shaping the continuum optical emission of this population. Finally, we explore a possible association of these sources and the moderate-z red (J-Ks>2mag) AGNs identified in the Two Micron All Sky Survey (2MASS). The median N_H of the red X-ray sources studied here is ~1e21cm^{-2}, lower than that found for the 2MASS AGNs, suggesting different populations.

Observation and modelling of urban dew
Creators: name: Richards, Katrina
Publisher: name: University of British Columbia
Year: 2009

description: Despite its relevance to many aspects of urban climate and to several practical questions, urban dew has largely been ignored. Here, simple observations, an outof- doors scale model, and numerical simulation are used to investigate patterns of dewfall and surface moisture (dew + guttation) in urban environments. Observations and modelling were undertaken in Vancouver, B.C., primarily during the summers of 1993 and 1996. Surveys at several scales (0.02-25 km) show that the main controls on dew are weather, location and site configuration (geometry and surface materials). Weather effects are discussed using an empirical factor, Φw. Maximum dew accumulation (up to ~0.2 mm per night) is seen on nights with moist air and high Φw, i.e., cloudless conditions with light winds. Favoured sites are those with high Ψsky and surfaces which cool rapidly after sunset, e.g., grass and well insulated roofs. A 1/8-scale model is designed, constructed, and run at an out-of-doors site to study dew patterns in an urban residential landscape which consists of house lots, a street and an open grassed park. The Internal Thermal Mass (ITM) approach is used to scale the thermal inertia of buildings. The model is validated using data from fullscale sites in Vancouver. Patterns in the model agree with those seen at the fullscale, i.e., dew distribution is governed by weather, site geometry and substrate conditions. Correlation is shown between Ψsky and surface moisture accumulation. The feasibility of using a numerical model to simulate urban dew is investigated using a modified version of a rural dew model. Results for simple isolated surfaces—a deciduous tree leaf and an asphalt shingle roof—show promise, especially for built surfaces.

description: The recent paper 1809.01197 described how states of a holographic CFT can be approximated by states of a large collection of non-interacting BCFTs, such that the dual of the new system accurately approximates an arbitrarily large causal patch of the original geometry. In this paper, we first describe in more detail the geometries dual to such discrete BCFT systems, emphasizing that they are multi-boundary wormholes in which it is not possible to move causally between different asymptotic regions. By reintroducing couplings between the BCFTs in various ways, we show that the wormholes can be made traversable, giving an intermediate class of geometries that interpolate between the multi-boundary wormhole and the original geometry that it approximates.

description: Mixed methods were used with various data sources to describe organisation and delivery of maternity care in Maputo city, Mozambique in early 2010s and to compare the plans with the service provision in practice. In the public health sector, maternity care was organised to be area based and hierarchical with a planned referral system. The provision of basic and emergency maternity care was publicly funded, largely dependent of donor funds, and free of charge for users. Even though Maputo City was better resourced than the rest of the country, there was a large lack of health professionals. Women’s choices and self-referrals, even to higher levels of care, were common, which broke the plans of areas responsibility, gate keeping and care by medical needs. Private services for maternity care had emerged for those who were able to pay, leading to dual practices of health professionals and shortage of care providers in the public system at odd hours. Information of maternity care was aggregate and poorly stored. The gap between “planned” services delivery and “practice” in a real-life requires overall health system strengthening to improve efficiency and effectiveness of health services delivery.

description: A survey of twenty-three soldier settlers who face adjustment problems following falls in sheep product prices and damage to pastures by a scarab pest is reported. Settlers estimates of input-output coefficients, and results from agronomic experiments, were used in formulating production possibilities in linear programming matrices. Normative plans for farm organization, to maximise incomes over a range of relative prices of agricultural and livestock products, were derived from these matrices by simplex programming. It was deduced that settlers could increase incomes by devoting all arable or potentially arable land to a cash crop rotation, even where pastures are not scarab infested. Once embarked on such a programme, substantial change in relative prices would be required before further adjustment was merited. Improved rotations for the district have been suggested by co-ordinating results from programming and agronomic experiments.

The lectotypes of the following taxa were designated: Serica flavimana Gory, 1832, Symmela angustula Moser, 1919, S. clypeata Erichson, 1835, S. corumbana Moser, 1921, S. instabilis Erichson, 1835, S. longula Erichson, 1835, S. mutabilis Erichson, 1835, S. nitidicollis Burmeister, 1855, S. opaca Erichson, 1835, S. tarsalis Moser, 1919, and S. tenella Erichson, 1835. Species are redescribed and a key to the species is given; details of external morphological features as well as the aedeagus are illustrated for all taxa. Distribution of the species is shown on a map. A phylogenetic analysis based on 137 morphological characters and parsimony indicates that Symmela is monophyletic. http://www.zoobank.org/urn:lsid:zoobank.org:pub:5147CC1B-6144-4CA4-BA63-E39ED0A20E1C

description: A method of designing asphaltic concrete overlays has been developed making use of (1) Kentucky's proposed design curves, (2) an estimate of future traffic and the associated fatigue (five procedures are presented according to types of information available), (3) strength of subgrade on subject project (laboratory CBR tests or results of dynamic in-place tests such as the Road Rater), and (4) present condition of the existing pavement (from dynamic in-place tests, roughness measurements, or present serviceability index). Deterioration was expressed as reduced thicknesses of new-quality materials producing the same measured dynamic deflections. The total thickness for the predicted traffic minus the effective or reduced thickness of the existing pavement is the overlay thickness required.

description: M 83 is one of the nearest galaxies with an enhanced nuclear star formation and it presents one of the best opportunities to study the kinematics and physical properties of a circumnuclear starburst. Our three-dimensional spectroscopy data in R band confirm the presence of a secondary nucleus or mass concentration (previously suggested by Thatte and coworkers). We determine the position of this hidden nucleus, which would be more massive than the visible one, and was not detected in the optical HST images due, probably, to the strong dust extinction. The optical nucleus has a mass of 5 x 10^6 M_Sun / sin i (r < 1''.5), and the hidden nucleus, located 3''.9 +/- 0''.5 at the NW (PA 271 +/- 15 deg) of the optical nucleus, would have a mass of 1 x 10^7 M_Sun / sin i (r < 1''.5). The emission line ratio map also unveils the presence of a second circumnuclear ring structure, previously discovered by IR imaging (Elmegreen and coworkers). The data allow us to resolve the behavior of the interstellar medium inside the circumnuclear ring and around the binary mass concentration.

description: The NANOGrav Collaboration recently reported a strong evidence for a stochastic common-spectrum process in the pulsar-timing data. We evaluate the evidence of interpreting this process as mergers of super massive black hole binaries and/or various stochastic gravitational wave background sources in the early Universe, including first-order phase transitions, cosmic strings, domain walls, and large amplitude curvature perturbations. We discuss the implications of the constraints on these possible sources. It is found that the cosmic string is the most favored source against other gravitational wave sources based on the Bayes factor analysis.

description: In the presence of the charged impurities, we study the weak localization (WL) effect by evaluating the quantum interference correction (QIC) to the conductivity of Dirac fermions in graphene. With the inelastic scattering rate due to electron-electron interactions obtained from our previous work, we investigate the dependence of QIC on the carrier concentration, the temperature, the magnetic field and the size of the sample. It is found that WL is present in large size samples at finite carrier doping. Its strength becomes weakened/quenched when the sample size is less than a few microns at low temperatures as studied in the experiments. In the region close to zero doping, the system may become delocalized. The minimum conductivity at low temperature for experimental sample sizes is found to be close to the data.

description: Although juniper (Juniperus communis) berry essential oil (JEO) has been used in skin care products, research on its biological activity in human skin cells is scarce. In the current study, we explored the biological activity of JEO (with alpha-pinene as the major active component) in pre-inflamed human dermal fibroblasts, which were designed to mimic the disease biology of chronic inflammation and fibrosis. We analyzed the levels of 17 important protein biomarkers pertinent to inflammation and tissue remodeling. JEO exhibited robust antiproliferative activity and significantly inhibited the increased production of the proinflammatory chemokines interferon gamma-induced protein 10 (IP-10) and interferon-inducible T-cell alpha chemoattractant (I-TAC). Additionally, JEO significantly inhibited tissue remodeling biomarkers, namely collagen I, collagen III, and plasminogen activator inhibitor 1 (PAI-I). Macrophage colony-stimulating factor (M-CSF), an immunomodulatory protein molecule, was also significantly downregulated by JEO. Moreover, we found that JEO robustly modulated global gene expression. Ingenuity Pathway Analysis also showed that JEO affected many important signaling pathways that are closely related to metabolism, inflammation, immune response, wound healing, and cancer biology. This study provides the first evidence of the biological activity of JEO in human dermal fibroblasts. Thus, JEO is a promising therapeutic candidate for inflammatory conditions in the skin.

description: A method of designing asphaltic concrete overlays has been developed from (1) Kentucky's theoretical design curves, (2) an estimate of future traffic and the associated fatigue (five procedures are presented according to types of information available), (3) strength of subgrade on subject project (laboratory CBR tests or results of dynamic in-place tests such as the Road Rater), and (4) present condition of the existing pavement (from dynamic in-place tests, roughness measurements, or present serviceability index). Deterioration has been expressed as reduced or effective thicknesses of new-quality materials producing the same measured dynamic deflections. The total thickness required for the future traffic minus the effective or reduced thickness of the existing pavement is the overlay thickness required.

description: Precision measurements, now and at a future linear electron-positron collider (ILC), can provide indirect information about the possible scale of supersymmetry. Performing a chi^2 analysis, we illustrate the present-day and possible future ILC sensitivities within the constrained minimal supersymmetric extension of the Standard Model (CMSSM), varying the parameters so as to obtain the cold dark matter density allowed by WMAP and other cosmological data. The current data are in very good agreement with the CMSSM prediction for tan beta = 10, with a clear preference for relatively small values of the universal gaugino mass, m_{1/2} \sim 300 GeV. In this case, there would be good prospects for observing supersymmetry directly at both the LHC and the ILC, and some chance already at the Tevatron collider. For tan beta = 50, the quality of the fit is worse, and somewhat larger m_{1/2} values are favoured. With the prospective ILC accuracies the sensitivity to indirect effects of supersymmetry greatly improves. This may provide indirect access to supersymmetry even at scales beyond the direct reach of the LHC or the ILC.

description: Interacting disordered zigzag graphene nanoribbons have fractional charges, are quasi-one-dimensional, and display an exponentially small gap. Our numerical computations showed that the topological entanglement entropy of these systems has a small finite but universal value, independent of the strength of the interaction and the disorder. The result that was obtained for the topological entanglement entropy shows that the disorder-free phase is critical and becomes unstable in the presence of disorder.

description: Cardamom (Elettaria cardamomum) essential oil (CEO) is popular in skin care, although no studies have reported its biological activity in human skin cells. We studied its effect on 17 protein biomarkers closely related to inflammation, immune responses, and tissue remodeling using a dermal fibroblast cell culture system designed to model chronic inflammation. CEO significantly inhibited the proliferation of skin cells and the expression of vascular cell adhesion molecule 1 (VCAM-1) and macrophage colonystimulating factor (M-CSF). The CEO-induced inhibition of the production of these protein biomarkers suggests its anti-inflammatory and immunomodulatory potential, which has been largely attributed to its major active component, eucalyptol. We further studied the effect of CEO on the expression of 21,224 genes in the same cell culture system. Ingenuity pathway analysis showed that CEO affected critical genes and signaling pathways closely involved in inflammation, immune responses, and tissue remodeling. The observed overall CEO-induced inhibition of these genes and pathways supports its anti-inflammatory and immunomodulatory properties. This study provides important evidence of the biological activity of CEO in human skin cells. Further research into the mechanism of action of CEO in human skin and other systems is recommended.

description: Two-dimensional hexagonal boron nitride (hBN) has attracted large attentions as platforms for realizations for integrated nanophotonics and collective effort has been focused on the spin defect centers. Here, the temperature dependence of the resonance spectrum in the range of 5-600 K is investigated. The zero-field splitting (ZFS) parameter D is found to decrease monotonicly with increasing temperature and can be described by Varshni empirical equation perfectly, while E almost does not change. We systematically study the differences among different hBN nanopowders and provide an evidence of edge effects on ODMR of VB- defects. Considering the proportional relation between D and reciprocal of lattice volume, the thermal expansion might be the dominant reason for energy-level shifts. We also demonstrate that the VB- defects still exist stably at least at 600 K. Moreover, we propose a scheme for detecting laser intensity using the VB- defects in hBN nanopowders, which is based on the obvious dependence of its D value on laser intensity. Our results are helpful to gain insight into the spin properties of VB- and for the realizations of miniaturized, integrated thermal sensor.

description: We report on observations of four early-type galaxies performed with the Rutgers Fabry-Perot in order to search for Planetary Nebulae (PNe) in these systems. The aim is to use the PNe as kinematic tracers of the galaxy potential. We describe our data reduction and analysis procedure and show that the proper calibration of our detection statistic is crucial in getting down to our limiting magnitude of $m_{5007} = 26.1$. In the case of the two Leo galaxies we find moderately sized samples: 54 PNe in NGC 3379 and 50 PNe in NGC 3384; NGC 4636 (2 PNe) and NGC 1549 (6 PNe) are included for completeness. We present our samples in tabular form, as well as the spectrum for each PN. We constructed simple non-parametric spherical mass models for NGC 3379 using a Monte Carlo Markov Chain method to explore the space of likely mass models. We find a remarkably constant mass-to-light ratio within five half-light radii with an overall $B$ band mass-to-light ratio $\sim 5$. A simple mass-to-light estimate for NGC 3384 yields $Υ_B \sim 11$, but is likely an overestimate.

description: Sleep disorders are associated with an elevated risk of developing various diseases. Herbal supplementation has been shown to alleviate sleep disorders such as insomnia. Here, the effect on sleep quality of an herbal supplement was evaluated subjectively. The supplement primarily contained lavender essential oil, as well as L-theanine and extracts of lemon balm, passion flower, and chamomile. Fifty-one healthy adults with self-reported symptoms of insomnia, divided into placebo and treatment groups, completed a 6-week crossover study (1-week washout, 2-week intervention, 1-week washout, and 2-week intervention, sequentially). Participants were asked to fill out the Leeds Sleep Evaluation Questionnaire (LSEQ) survey weekly and keep a sleep diary daily, which were used to assess their sleep quality. Compared to the placebo group, the active group (participants who received the supplement) showed significant improvements in overall LSEQ scores (p
Supersymmetric solutions from N=6 gauged supergravity

description: We study supersymmetric solutions in four-dimensional $N=6$ gauged supergravity with $SO(6)$ gauge group. There is a unique $N=6$ supersymmetric $AdS_4$ vacuum with $SO(6)$ symmetry dual to an $N=6$ SCFT in three dimensions. We find a number of domain walls interpolating between this $AdS_4$ vacuum and singular geometries in the IR with $SO(2)\times SO(4)$, $U(3)$, $SO(3)$ and $SO(2)\times SO(2)\times SO(2)$ symmetries. The $SO(3)$ case admits $N=6$ or $N=2$ solutions depending on whether the pseudoscalars are present or not. On the other hand, all the remaining solutions preserve $N=6$ supersymmetry. These solutions describe RG flows from the $N=6$ SCFT to non-conformal field theories driven by mass deformations. In particular, the $SO(2)\times SO(4)$ solution is in agreement with the previously known mass deformations of the dual $N=6$ SCFT. We also give a supersymmetric Janus solution with $SO(2)\times SO(4)$ symmetry, describing two-dimensional conformal defects in the $N=6$ SCFT with unbroken $N=(4,2)$ supersymmetry. Finally, we find an $N=2$ supersymmetric $AdS_2\times H^2$ solution with $SO(2)\times SO(4)$ symmetry and the corresponding domain wall interpolating between this fixed point and the $AdS_4$ vacuum. The solution describes an $AdS_4$ black hole with a magnetic charge and is dual to a twisted compactification of the $N=6$ SCFT on a hyperbolic space $H^2$. We also give a domain wall interpolating between a locally supersymmetric $AdS_4$ and a curved domain wall with $SO(2)\times SO(2)\times SO(2)$ symmetry dual to an RG flow across dimensions from the $N=6$ SCFT to a supersymmetric quantum mechanics.

description: We report on a new experiment that tests for a violation of Lorentz invariance (LI), by searching for a dependence of atomic transition frequencies on the orientation of the spin of the involved states (Hughes-Drever type experiment). The atomic frequencies are measured using a laser cooled $^{133}$Cs atomic fountain clock, operating on a particular combination of Zeeman substates. We analyze the results within the framework of the Lorentz violating standard model extension (SME), where our experiment is sensitive to a largely unexplored region of the SME parameter space, corresponding to first measurements of four proton parameters and improvements by 11 and 13 orders of magnitude on the determination of four others. In spite of the attained uncertainties, and of having extended the search into a new region of the SME, we still find no indication of LI violation.
