description: During the total solar eclipse of 11 July 2010, multi-slit spectroscopic observations of the solar corona were performed from Easter Island, Chile. To search for high-frequency waves, observations were taken at a high cadence in the green line at 5303 A due to [Fe xiv] and the red line at 6374 A due to [Fe x]. The data are analyzed to study the periodic variations in the intensity, Doppler velocity and line width using wavelet analysis. The data with high spectral and temporal resolution enabled us to study the rapid dynamical changes within coronal structures. We find that at certain locations each parameter shows significant oscillation with periods ranging from 6 - 25 s. For the first time, we could detect damping of high-frequency oscillations with periods of the order of 10 s. If the observed damped oscillations are due to magnetohydrodynamic (MHD) waves then they can contribute significantly in the heating of the corona. From a statistical study we try to characterize the nature of the observed oscillations while looking at the distribution of power in different line parameters.

description: In the present work we analyze the second order transition line that connect the tricritical point and the quantum critical ending point on the temperature--magnetic-field plane in UGe$_2$. For the microscopic modeling we employ the Anderson lattice model recently shown to provide a fairly complete description of the full magnetic phase diagram of UGe$_2$ including all the criticalities. The shape of the so-called tricritical wings, i.e. surfaces of the first-order transitions, previously reported by us to quantitatively agree with the experimental data, is investigated here with respect to the change of the total filling and the Landé factor for $f$ electrons which can differ from the free electron value. The analysis of the total filling dependence demonstrates sensitivity of our prediction when the respective positions of the critical ending point at the metamagnetic transition and tricritical point are mismatched as compared to the experiment.

description: In the past five years, approximately one third of the 65 pulsars discovered by radio observations of Fermi unassociated sources are black widow pulsars (BWPs). BWPs are binary millisecond pulsars with companion masses ranging from 0.01-0.1 solar masses which often exhibit radio eclipses. The bloated companions in BWP systems exert small torques on the system causing the orbit to change on small but measurable time scales. Because adding parameters to a timing model reduces sensitivity to a gravitational wave (GW) signal, the need to fit many orbital frequency derivatives to the timing data is potentially problematic for using BWPs to detect GWs with pulsar timing arrays. Using simulated data with up to four orbital frequency derivatives, we show that fitting for orbital frequency derivatives absorbs less than 5% of the low frequency spectrum expected from a stochastic gravitational wave background signal. Furthermore, this result does not change with orbital period. Therefore, we suggest that if timing systematics can be accounted for by modeling orbital frequency derivatives and is not caused by spin frequency noise, pulsar timing array experiments should include BWPs in their arrays.

Development of a Causal Connectome in Major Depressive Disorder Using Machine Learning

Subjects: subject: Magnetic brain stimulation

description: Major depressive disorder (MDD) is the leading cause of disability worldwide, affecting more than 300 million people [1, 2]. While the first and primary approach to treating MDD is with antidepressant medications, transcranial magnetic stimulation (TMS) is an emerging non-invasive tool for stimulating brain networks and has proven to be effective for treatment of MDD [3, 4]. Currently, TMS for MDD targets the depression pathophysiology at the left DLPFC [12]. However, relatively low response rates have been observed when TMS is administered in the DLPFC, with other brain regions such as the medial prefrontal cortex (MPFC) or the anterior insula showing promise [13-15]. Therefore, we analyze functional connectivity networks to 1) better understand the pathophysiology of MDD and 2) elucidate potential novel treatment targets. We record TMS-evoked potentials (TEP) from 6 regions of interests (ROIs) that broadly covered the brain for 38 medication-free healthy patients and 27 patients with MDD after single pulses of TMS in 26 stimulation sites across the brain. We hypothesized that the local (left prefrontal) early TEP (20-80ms) after stimulation is more effective at differentiating between patients with MDD and healthy controls based on previous studies [30, 31]. However, we found that the early TEPs (20-80ms) were not able to differentiate between the MDD subgroup and the healthy patient subgroup. Furthermore, our results demonstrated that brain responses from TMS were not localized in the DLPFC, but at various regions of the brain such as the central and occipital regions. There was spatial variance identified in these connectivity networks between stimulation sites and ROIs widespread across the brain. Together, this work reveals that there is greater spatial and temporal diversity in connectivity networks of MDD.

description: In recent work we have shown how an accurate reduced model can be utilized to perform mesh refinement in random space. That work relied on the explicit knowledge of an accurate reduced model which is used to monitor the transfer of activity from the large to the small scales of the solution. Since this is not always available, we present in the current work a framework which shares the merits and basic idea of the previous approach but does not require an explicit knowledge of a reduced model. Moreover, the current framework can be applied for refinement in both random and physical space. In this manuscript we focus on the application to random space mesh refinement. We study examples of increasing difficulty (from ordinary to partial differential equations) which demonstrate the efficiency and versatility of our approach. We also provide some results from the application of the new framework to physical space mesh refinement.

description: We demonstrate a broadband, polarization independent, omnidirectional absorber based on a metallic metasurface architecture, which accomplishes greater than 90% absorptance in the visible and near-infrared range of the solar spectrum, and exhibits low emissivity at mid- and far-infrared wavelengths. The complex unit cell of the metasurface solar absorber consists of eight pairs of gold nano-resonators that are separated from a gold ground plane by a thin silicon dioxide spacer. Our experimental measurements reveal high-performance absorption over a wide range of incidence angles for both s- and p-polarizations. We also investigate numerically the frequency-dependent field and current distributions to elucidate how the absorption occurs within the metasurface structure. Furthermore, we discuss the potential use of our metasurface absorber design in solar thermophotovoltaics by exploiting refractory plasmonic materials.

description: A structural theorem for Kleene algebras is proved, showing that an element of a Kleene algebra can be looked upon as an ordered pair of sets. Further, we show that negation with the Kleene property (called the `Kleene negation') always arises from the set theoretic complement. The corresponding propositional logic is then studied through a 3-valued and rough set semantics. It is also established that Kleene negation can be considered as a modal operator, and enables giving a perp semantics to the logic. One concludes with the observation that all the semantics for this logic are equivalent.

description: At the GIS-studio of the Faculty of Science (FNWI) at the University of Amsterdam, a project has been completed in which two maps (models) are produced in 3D using ArcGIS, Blender and a 3D printer. 3D printing is an emerging technology in both science and in business, fine arts and for everyday objects. With the advent of LiDAR (Light Detection And Ranging), a relatively new remote sensing technology, more and more detailed digital elevation models are being produced, displaying the Earth's surface in 3D in very high detail. 3D printing offers an excellent supplement, because with the use of it, it is not necessary to visualize and analyze 3D data in 2D, but the data can be studied directly in 3D. A tutorial has been developed for making 3D-printed models from digital height models, which is included as an English appendix at the end of this document.

description: We use cosmological simulations to identify dark matter subhalo host candidates of the Fornax dwarf spheroidal galaxy using the stellar kinematic properties of Fornax. We consider cold dark matter (CDM), warm dark matter (WDM), and decaying dark matter (DDM) simulations for our models of structure formation. The subhalo candidates in CDM typically have smaller mass and higher concentrations at z = 0 than the corresponding candidates in WDM and DDM. We examine the formation histories of the ~ 100 Fornax candidate subhalos identified in CDM simulations and, using approximate luminosity-mass relationships for subhalos, we find two of these subhalos that are consistent with both the Fornax luminosity and kinematics. These two subhalos have a peak mass over ten times larger than their z = 0 mass. We suggest that in CDM the dark matter halo hosting Fornax must have been severely stripped of mass and that it had an infall time into the Milky Way of ~ 9 Gyr ago. In WDM, we find that candidate subhalos consistent with the properties of Fornax have a similar infall time and a similar degree of mass loss, while in DDM we find a later infall time of ~ 3 - 4 Gyr ago and significantly less mass loss. We discuss these results in the context of the Fornax star formation history, and show that these predicted subhalo infall times can be linked to different star formation quenching mechanisms. This emphasizes the links between the properties of the dark matter and the mechanisms that drive galaxy evolution.

Low-wage mobility during the early career

description: Despite the size of the low-wage workforce, knowledge of the low-wage labor market is markedly sparse. In particular, little is known about the mobility patterns of low-wage workers. Using data from the Panel Study of Income Dynamics, I analyze low-wage mobility during the early career. I find that exits from low-wages are common, but the odds of exit and the permanence of an exit vary by social group membership and have changed in recent decades. Women, African Americans, and the less educated fare worse in the low-wage labor market. My findings also suggest that low-wage mobility has changed since the 1970s, with low-wages becoming more difficult to avoid.

The present calculations are based on using two types of compact and accurate trial wave functions, which are put forward for consideration in calculating energies in the absence of magnetic field. The obtained results are compared with the most recent accurate values. We conclude that the applications of VMC method can be extended successfully to cover the case of molecules under the effect of the magnetic field.

Virasoro vacuum block at next-to-leading order in the heavy-light limit

description: We consider the semiclassical limit of the vacuum Virasoro block describing the diagonal 4-point correlation functions on the sphere. At large central charge c, after exponentiation, it depends on two fixed ratios h_H/c and h_L/c, where h_{H, L} are the conformal dimensions of the 4-point function operators. The semiclassical block may be expanded in powers of the light ratio h_L/c and the leading non-trivial (linear) order is known in closed form as a function of h_H/c. Recently, this contribution has been matched against AdS_3 gravity calculations where heavy operators build up a classical geometry corresponding to a BTZ black hole, while the light operators are described by a geodesic in this background. Here, we compute for the first time the next-to-leading quadratic correction O((h_L/c)^{2}), again in closed form for generic heavy operator ratio h_H/c. The result is a highly non-trivial extension of the leading order and may be relevant for further refined AdS_{3}/CFT_{2} tests. Applications to the two-interval Rényi entropy are also presented.

description: We observed the Seyfert 1 galaxy NGC 985 on multiple occasions to search for variability in its UV and X-ray absorption features in order to establish their location and physical properties. We use XMM-Newton to obtain X-ray spectra using the EPIC-pn camera, and the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope (HST) to obtain UV spectra. Our observations are simultaneous and span timescales of days to years. We find that the soft X-ray obscuration that absorbed the low energy continuum of NGC 985 in August 2013 diminished greatly by January 2015. The total X-ray column density decreased from 2.1 x 10^22 cm^-2 to ~6 x 10^21 cm^-2. We also detect broad, fast UV absorption lines in COS spectra obtained during the 2013 obscuration event. Lines of C III*, Ly alpha, Si IV and C IV with outflow velocities of -5970 km/s and a full-width at half-maximum of 1420 km/s are prominent in the 2013 spectrum, but have disappeared in all but Ly alpha in the 2015 spectra. The ionization state and the column density of the UV absorbing gas is compatible with arising in the same gas as that causing the X-ray obscuration. The high velocity of the UV-absorbing gas suggests that the X-ray obscurer and the associated UV outflow are manifestations of an accretion disk wind.

description: The exact solution, via transfer matrix, of the simple one dimensional lattice Coulomb gas (1d LCG) model can reproduce peculiar features of ionic liquid capacitors, such as overscreening, layering, and camel- and bell-shaped capacitance curves. Using the same transfer matrix method, we now compute the bulk properties of the 1d LCG in the constant voltage ensemble. We unveil a phase diagram with rich structure exhibiting a low density disordered and high density ordered phases, separated by a first order phase transition at low temperature; the solid state at full packing can be ordered or not, depending on the temperature. This phase diagram, which is strikingly similar to its three dimensional counterpart, also sheds light on the behaviour of the confined system.

description: Analysis of a longitudinal wave event observed by the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO) is presented. A time sequence of 131 A images reveals that a C-class flare occurred at one footpoint of a large loop and triggered an intensity disturbance (enhancement) propagating along it. The spatial features and temporal evolution suggest that a fundamental standing slow-mode wave could be set up quickly after meeting of two initial disturbances from the opposite footpoints. The oscillations have a period of ~12 min and a decay time of ~9 min. The measured phase speed of 500$\pm$50 km/s matches the sound speed in the heated loop of ~10 MK, confirming that the observed waves are of slow mode. We derive the time-dependent temperature and electron density wave signals from six AIA extreme-ultraviolet (EUV) channels, and find that they are nearly in phase.The measured polytropic index from the temperature and density perturbations is 1.64$\pm$0.08 close to the adiabatic index of 5/3 for an ideal monatomic gas. The interpretation based on a 1D linear MHD model suggests that the thermal conductivity is suppressed by at least a factor of 3 in the hot flare loop at 9 MK and above. The viscosity coefficient is determined by coronal seismology from the observed wave when only considering the compressive viscosity dissipation. We find that to interpret the rapid wave damping, the classical compressive viscosity coefficient needs to be enhanced by a factor of 15 as the upper limit.

description: Covariation between internalizing and externalizing problems is typically summarized using correlations. This assumes the same covariation pattern holds for all children, but there are empirical and theoretical rationales for qualitatively different patterns over time. In this study, growth mixture modeling of 8 waves of mother-reported internalizing and externalizing symptoms (ages 2-11; N=1,222) from the NICHD Study of Early Child Care were used to test four theories of internalizing/externalizing covariation. Growth mixture modeling probabilistically links developmental courses of internalizing and externalizing symptoms, while capturing heterogeneity in the expression of each. Results showed that stable covariation occurred at all levels of behavior (high, moderate, and low), for all functional forms of behavior (decreasing, persisting, or low-stable), and for the majority of children. Unique patterns of differentiation with development (among one fifth of boys) and rising internalizing (among one fifth of girls) evidenced in this study would have been obscured using correlational analyses.

description: The innovation anticipated here is the use of our previously prepared chitosan nanoparticles in conjunction with citric acid and sodium hypophosphite for rendering viscose fabrics dyed and finished concurrently in one step with dual classes of dyes, namely basic and acid dyes, using a pad-dry-cure process. This was done to see the effect of the aforementioned eco-friendly finishing formulation on creating dual anchoring sites onto finished fabrics for dye-ability using Basic Red 2 and Acid Orange 7, which have no direct affinity to viscose fabric. So, different concentrations of CA, CNPs, and dyes were mixed into a viscose fabric cross-linking formulation together with a set concentration of SHP (50% based on weight of CA concentration) and cured at 170°C for 2 minutes. Citric acid is predicted to react with the hydroxyl groups in viscose and CNPs to produce ester crosslinking and/or to form an inter-ionic attraction with the amino groups of CNPs. The latter was responsible for viscose fabrics dye ability with Basic Red 2 by anchoring the free carboxyl groups in citric acid, as well as their dye ability with Acid Orange 7 by anchoring the residual amine groups in CNPs.

description: Non-invasive and ultra-accurate optical manipulation of nanometer objects has recently gained a growing interest as a powerful enabling tool in nanotechnology and biophysics. In this context, Self-Induced Back-Action (SIBA) trapping in nano-optical cavities has shown a unique potential for trapping and manipulating nanometer-sized objects under low optical intensities. Yet, the existence of the SIBA effect has that far only been evidenced indirectly through its enhanced trapping performances. In this article we present for the first time a direct experimental evidence of the self-reconfiguration of the optical potential experienced by a nanoparticle trapped in a plasmonic nanocavity. Our observations enable us gaining further understanding of the SIBA mechanism and determine the optimum conditions to boost the performances of SIBA-based nano-optical tweezers.

description: Eucalyptus globulus bio extract was applied on woven cotton textiles for antibacterial and aroma finish. Molecular characterisation was done by using FTIR. Chemical groups responsible for antibacterial behaviour and the chemical structure of this plant were investigated through GCMS. Eucalyptus globulus treated fabric has greater colour depth (K/S) in comparison to original fabric. The mordanted fabrics were treated with Eucalyptus globulus solution and evaluated for antibacterial activity against Escherichia.coli (Gram negative bacteria) and Staphylococcus aureus (Gram-positive bacteria) by Agar Well Diffusion method. Zone of inhibition of 16 mm to 26 mm was measured for the different treated fabrics against Escherichia.coli (Gram negative bacteria) in comparison to 18 mm to 32 mm for Staphylococcus aureus (Gram-positive bacteria). Zone of inhibition in treated fabrics reveal that the antibacterial effect is more potent against gram positive bacteria. There is decrease in zone of inhibition for both gram negative and gram positive bacteria after 20 washing cycles. However, Eucalyptus globulus treated fabric can retain 56.2% to 88.5% of its initial antibacterial property even after 20 washing cycles. Cotton fabrics also generate fragrance after treatment. Fragrance intensity ratings of 200 respondents have been documented and evaluated.

description: As a model for an on-line classification setting we consider a stochastic process $(X_{-n},Y_{-n})_{n}$, the present time-point being denoted by 0, with observables $ \ldots,X_{-n},X_{-n+1},\ldots, X_{-1}, X_0$ from which the pattern $Y_0$ is to be inferred. So in this classification setting, in addition to the present observation $X_0$ a number $l$ of preceding observations may be used for classification, thus taking a possible dependence structure into account as it occurs e.g. in an ongoing classification of handwritten characters. We treat the question how the performance of classifiers is improved by using such additional information. For our analysis, a hidden Markov model is used. Letting $R_l$ denote the minimal risk of misclassification using $l$ preceding observations we show that the difference $\sup_k |R_l - R_{l+k}|$ decreases exponentially fast as $l$ increases. This suggests that a small $l$ might already lead to a noticeable improvement. To follow this point we look at the use of past observations for kernel classification rules. Our practical findings in simulated hidden Markov models and in the classification of handwritten characters indicate that using $l=1$, i.e. just the last preceding observation in addition to $X_0$, can lead to a substantial reduction of the risk of misclassification. So, in the presence of stochastic dependencies, we advocate to use $ X_{-1},X_0$ for finding the pattern $Y_0$ instead of only $X_0$ as one would in the independent situation.

description: Graphene-based electroconductive textile materials are advantageous over metal/gel-based heating pads for thermotherapy because of their flexibility, processability, and ability to maintain a constant temperature for an extended period. The electro-thermal properties of graphene-based nonwoven depend on its surface resistivity which in turn depends on the amount of graphene oxide (GO) deposition. In this work, highly conductive, flexible, lightweight, and antibacterial graphene functionalized cotton nonwoven with excellent electro-thermal performance is reported. For this, needle punched nonwoven structure is designed and its construction variables (Fabric GSM, punch density, and depth of penetration) are optimized with the Box-Behnken response surface design to achieve maximum GO adsorption and minimum surface resistivity. The lowest surface resistivity of 727.57 Ω sq−1 is achieved at 22.18% GO add-on. The functionalized fabric shows excellent electro-thermal properties and a maximum surface temperature of 118°C is achieved at 30V DC supply. The change in surface resistivity of rGO-cotton (reduced graphene oxide coated cotton) is insignificant even after atmospheric aging for 10 weeks, 4 washings and 10 rubbings. Antibacterial activity of 97.10% is achieved toward Staphylococcus aureus bacterium.
