description: We argue that certain apparently consistent low-energy effective field theories described by local, Lorentz-invariant Lagrangians, secretly exhibit macroscopic non-locality and cannot be embedded in any UV theory whose S-matrix satisfies canonical analyticity constraints. The obstruction involves the signs of a set of leading irrelevant operators, which must be strictly positive to ensure UV analyticity. An IR manifestation of this restriction is that the "wrong" signs lead to superluminal fluctuations around non-trivial backgrounds, making it impossible to define local, causal evolution, and implying a surprising IR breakdown of the effective theory. Such effective theories can not arise in quantum field theories or weakly coupled string theories, whose S-matrices satisfy the usual analyticity properties. This conclusion applies to the DGP brane-world model modifying gravity in the IR, giving a simple explanation for the difficulty of embedding this model into controlled stringy backgrounds, and to models of electroweak symmetry breaking that predict negative anomalous quartic couplings for the W and Z. Conversely, any experimental support for the DGP model, or measured negative signs for anomalous quartic gauge boson couplings at future accelerators, would constitute direct evidence for the existence of superluminality and macroscopic non-locality unlike anything previously seen in physics, and almost incidentally falsify both local quantum field theory and perturbative string theory.

description: Relative attributes indicate the strength of a particular attribute between image pairs. We introduce a deep Siamese network with rank SVM loss function, called Deep Rank SVM (DRSVM), in order to decide which one of a pair of images has a stronger presence of a specific attribute. The network is trained in an end-to-end fashion to jointly learn the visual features and the ranking function. We demonstrate the effectiveness of our approach against the state-of-the-art methods on four image benchmark datasets: LFW-10, PubFig, UTZap50K-lexi and UTZap50K-2 datasets. DRSVM surpasses state-of-art in terms of the average accuracy across attributes, on three of the four image benchmark datasets.

description: We have studied the UV spectral behavior of the recurrent nova T Pyx during 16 years of IUE observations. We examined both the IUE line-by-line images and the extracted spectra in order to understand the reality and the origin of the observed spectral variations. The UV continuum of T Pyx has remained nearly constant in slope and intensity over this time interval, without any indication of long-term trends. The reddening determined from the UV data is E(B-V}=0.25 \pm 0.02. The best single-curve fit to the dereddened UV continuum is a power-law distribution $\propto λ^{-2.33}$. The tail of this curve agrees well with the B, V, and J magnitudes of T Pyx, indicating that the contribution of the secondary star is negligible. One peculiar aspect of T Pyx is that most emission lines (the strongest ones being those of CIV 1550 and HeII 1640) show substantial changes both in intensity and detectability, in contrast to the near constancy of the continuum. Several individual spectra display emission features that are difficult to identify, suggesting a composite spectroscopic system. We tentatively ascribe the origin of these transient emission features either to loops and jets from the irradiated secondary or to moving knots of the surrounding nebula that are (temporarily) projected in front of the system. The inspection of all IUE line-by-line images has led to the detection of emission spikes outside the central strip of the spectrum, which in some cases seem associated to known emission features in the (main) spectrum. A comparison with other ex-novae reveals a surprising similarity to the spectrum of the very-slow nova HR Del, whose white dwarf primary has a mass that is allegedly about one half that of T Pyx.

description: Необходимость оптимизации состава желейного мармелада за счет использования природного сырья обусловлена тем, что искусственные красители и ароматизаторы могут быть небезопасными для организма. Показана возможность применения настоя лепестков розеллы («Каркадэ») в составе мармелада как источника антоцианов, флавонолов и других полифенольных соединений, оказывающих гипотензивное и капилляроукрепляющее действие. Обогащающей добавкой явилась аскорбиновая кислота, проявляющая с полифенолами синергический эффект. Исследования проводились на базе Сибирского университета потребительской кооперации, лаборатории Центра гигиены и эпидемиологии Омской области. Применялись стандартизированные методы исследования настоя и мармелада. Определение антоцианов в пересчете на цианид-3-глюкозид проводилось модифицированным спектрофотометрическим методом. Настой получали из сухого измельченного сырья водной экстракцией (1:10). Добавление перед экстракцией 1,2 г лимонной кислоты снижает рН настоя до 2,2, повышает выход и стабилизацию антоцианов, что, вероятно, обусловлено снижением активности фермента полифенолоксидазы и образованием комплексов цитрат-ионов. Впервые разработаны рецептуры мармелада «Каркадэ» c соотношением сахара, настоя и лимонной кислоты (%): 53:15:0,4. Количество аскорбиновой кислоты при ее использовании составило 2 г/кг. Показатели качества мармелада соответствовали требованиям ГОСТ 6442. Рекомендовано хранить мармелад при температуре 10±3 °C и относительной влажности воздуха 75±5 % в закрытых непрозрачных коробках. После 3 месяцев хранения содержание антоцианов в 50 г мармелада составило 26,2 %, аскорбиновой кислоты - 77,6 %, марганца - 10,25 % от рекомендуемой суточной нормы потребления для взрослых, что позволяет считать желейный мармелад «Каркадэ» продуктом повышенной физиологической ценности. Было обнаружено определенное положительное воздействие аскорбиновой кислоты на сохранность антоцианов.

description: We compute an effective action for a composite Higgs boson formed by new fermions belonging to a general technicolor non-Abelian gauge theory, using a quite general expression for the fermionic self-energy that depends on a certain parameter (alpha), that defines the technicolor theory from the extreme walking behavior up to the one with a standard operator product expansion behavior. We discuss the values of the trilinear and quadrilinear scalar couplings. Our calculation spans all the possible physical possibilities for mass and couplings of the composite system. In the case of extreme walking technicolor theories we verify that it is possible to have a composite Higgs boson with a mass as light as the present experimental limit, contrary to the usual expectation of a heavy mass for the composite Higgs boson. In this case we obtain an upper limit for the Higgs boson mass, M_H ~ 700GeV for SU(2)_TC, and the experimental data on the Higgs boson mass constrain SU(N)_TC technicolor gauge groups to be smaller than SU(10)_TC.

description: BlueMUSE (Blue Multi Unit Spectroscopic Explorer) is a blue-optimised, medium spectral resolution, panoramic integral field spectrograph proposed for the Very Large Telescope (VLT) and based on the MUSE concept. BlueMUSE will open up a new range of galactic and extragalactic science cases allowed by its specific capabilities in the 350 - 580 nm range: an optimised end-to-end transmission down to 350 nm, a larger FoV (up to $1.4 \times 1.4$ arcmin$^2$) sampled at 0.3 arcsec, and a higher spectral resolution ($λ/Δλ\sim 3500$) compared to MUSE. To our knowledge, achieving such capabilities with a comparable mechanical footprint and an identical detector format ($4\text{k} \times 4\text{k}$, 15 $\mathrm{μm}$ CCD) would not be possible with a conventional spectrograph design. In this paper, we present the optomechanical architecture and design of BlueMUSE at pre-phase A level, with a particular attention to some original aspects such as the use of curved detectors.

description: Lattice structures are frequently found in nature and engineering due to their myriad attractive properties, with applications ranging from molecular to architectural scales. Lattices have also become a key concept in additive manufacturing, which enables precise fabrication of complex lattices that would not be possible otherwise. While design and simulation tools for stiff lattices are common, here we present a digital design and nonlinear simulation approach for additive manufacturing of soft lattices structures subject to large deformations and instabilities, for which applications in soft robotics, healthcare, personal protection, energy absorption, fashion and design are rapidly emerging. Our framework enables design of soft lattices with curved members conforming to freeform geometries, and with variable, gradually changing member thickness and material, allowing the local control of stiffness. We model the lattice members as 3D curved rods and using a spline-based isogeometric method that allows the efficient simulation of nonlinear, large deformation behavior of these structures directly from the CAD geometries. Furthermore, we enhance the formulation with a new joint stiffening approach, which is based on parameters derived from the actual node geometries. Simulation results are verified against experiments with soft lattices realized by PolyJet multi-material polymer 3D printing, highlighting the potential for simulation-driven, digital design and application of non-uniform and curved soft lattice structures.

subject: Indonesia Politics and government

description: This thesis investigates the emergence and growth of Hizbut Tahrir Indonesia (HTI; Party of Liberation). HTI is a branch of the international movement, Hizb ut-Tahrir. The party has been very successful at utilising political space to recruit and mobilize activists, build loyaI cadres with a deep grasp of its ideology, and most importantly, create a common identity among members. Its ability to forge a collective identity within the movement has led to a high rate of membership retention. Drawing on extensive interviews conducted in the field, the thesis describes the journey a person undergoes before becoming a member of HTI. The interviews will focus on the processes of 'culturing' and socialization to which prospective recruits are subject, which result in behavioural, cognitive and affective changes. It is this transformation that produces a distinctive Hizb ut-Tahrir identity. This study notes that while collective identity is the most important factor in HTI's growth, it is by no means the only one. Other factors have also contributed to its growth. The open political system that followed the collapse of the authoritarian New Order govemment enabled the party to emerge publicly after some two decades of underground activity, and begin overtly recruiting members and launching collective actions. I examine the party's resource mobilization strategies and examine how these strategies have resulted in its successful membership recruitment, raising of funds and expansion of its organizational structure. Consideration is also given to how the party's anti-systemic rationalistic ideology has led to potential members choosing HTI over other Islamist movements in Indonesia. This thesis employs a structural-cognitive approach to understanding the growth of HTI. The political opportunity structure and resource mobilization variant of the social movement theory will be utilized to understand the structural factors that impacted HTI. The cognitive factors will be explained by using the theories of ideology and identity. This theoretical approach allows for a more comprehensive understanding of HTI's growth.

description: We introduce an inhomogeneously-nonlinear Schr{ö}dinger lattice, featuring a defocusing segment, a focusing segment and a transitional interface between the two. We illustrate that such inhomogeneous settings present vastly different dynamical behavior than the one expected in their homogeneous counterparts in the vicinity of the interface. We analyze the relevant stationary states, as well as their stability by means of perturbation theory and linear stability analysis. We find good agreement with the numerical findings in the vicinity of the anti-continuum limit. For larger values of the coupling, we follow the relevant branches numerically and show that they terminate at values of the coupling strength which are larger for more extended solutions. The dynamical development of relevant instabilities is also monitored in the case of unstable solutions.

description: Introduced in 1996 by the newly elected Howard Government, the Temporary Business Visas (long stay) Subclass 457 visa has become an important yet controversial element of Australia's migration program. Allowing the temporary migration of workers for a period of between three months and four years, the 457 visa program is based on the need for such workers to be sponsored by an eligible employer while they are in Australia. Criticism of the program has focused on the exploitation and mistreatment of workers that has been uncovered, much of it linked to the uneven power dynamics that exist due to this need for sponsorship. In addition to these controversies, there has been discussion of the program's role in the purported shift away from permanent towards temporary migration and the related influence of globalisation on its development and operation. Acknowledging that there has been debate over the concept of globalisation, this thesis takes a sceptical view of the concept and investigates the claims made by scholars and politicians that the 457 visa program is a response to globalisation. To do this, it measures the program against five criteria for a globalised worker migration program: it is unprecedented; it allows participants to engage in a global labour market; it provides evidence of the decline in the importance of the nation; it shows the diminishing power of the state; and it demonstrates the increasing power of the business community. This thesis finds that while there is superficial evidence suggesting that the 457 visa program is a response to globalisation, as measured by these criteria, a more detailed examination raises considerable doubts over such claims. It is shown that in contrast, an anti-capitalist analysis of the program provides useful insights into its operation. Further, it demonstrates how the concept of globalisation can be used to disguise the growing influence of both the state and the business community while also making it difficult for opponents of the 457 visa program to criticise it.
Using Mobile Data Collectors to Federate Clusters of Disjoint Sensor Network Segments
Creators: name: Kalyanasundaram, Bhuvana
Publisher: name: Maryland Shared Open Access Repository
Year: 2012

description: Wireless Sensor Networks (WSN) operating unattended in harsh environments have the higher probability of suffering from large scale damage, where many nodes fail simultaneously and the network gets partitioned into several disjoint segments. Restoring connectivity of structurally damaged WSN's segments may be very urgent considering that they are employed to assist in risky missions. A similar scenario is when multiple standalone networks are to be federated to serve an emerging event such as an earthquake and conduct search-and-rescue. To deal with these scenarios, Mobile Data Mules (MDMs) are employed to establish intermittent links by moving around and carrying data from one segment to another. To limit data delivery latency and minimize the motion overhead, the travel path of the MDM should be shortened. When the availability of MDMs is not an issue, a minimum spanning tree of the segment is formed and one MDM is assigned to serve each link on the tree, i.e., a total of (N-1) mules are involved where N is the number of segments. In this thesis, we study a constrained version of the federation problem when the number of MDM's k is less than (N-1), which makes the problem more challenging. We present a novel algorithm that groups the segments into k overlapping clusters based on the inter-segment proximity. Each cluster is assigned a distinct MDM to tour its segments. A segment that belongs to two clusters serves as a gateway that enables data transfer across clusters. Our algorithm minimizes the tour length for each MDM and sets the speed of the individual MDMs to rendezvous at the gateway nodes so that buffering space and time for inter-cluster traffic are minimized. The simulation results confirm the effectiveness of our algorithm.

description: We report three-dimensional hydrodynamical simulations of shocks (${\cal M_{\rm shock}}\geq 4$) interacting with fractal multicloud layers. The evolution of shock-multicloud systems consists of four stages: a shock-splitting phase in which reflected and refracted shocks are generated, a compression phase in which the forward shock compresses cloud material, an expansion phase triggered by internal heating and shock re-acceleration, and a mixing phase in which shear instabilities generate turbulence. We compare multicloud layers with narrow ($σ_ρ=1.9\barρ$) and wide ($σ_ρ=5.9\barρ$) log-normal density distributions characteristic of Mach $\approx 5$ supersonic turbulence driven by solenoidal and compressive modes. Our simulations show that outflowing cloud material contains imprints of the density structure of their native environments. The dynamics and disruption of multicloud systems depend on the porosity and the number of cloudlets in the layers. `Solenoidal' layers mix less, generate less turbulence, accelerate faster, and form a more coherent mixed-gas shell than the more porous `compressive' layers. Similarly, multicloud systems with more cloudlets quench mixing via a shielding effect and enhance momentum transfer. Mass loading of diffuse mixed gas is efficient in all models, but direct dense gas entrainment is highly inefficient. Dense gas only survives in compressive clouds, but has low speeds. If normalised with respect to the shock-passage time, the evolution shows invariance for shock Mach numbers $\geq10$ and different cloud-generating seeds, and slightly weaker scaling for lower Mach numbers and thinner cloud layers. Multicloud systems also have better convergence properties than single-cloud systems, with a resolution of $8$ cells per cloud radius being sufficient to capture their overall dynamics.

description: `Visual inspection of produce fields for signs of fecal contamination and animal intrusion prior to harvest is a currently prescribed method for reducing risk of foodborne illnesses. This report details the continuing development of a fluorescence imaging system to augment human visual inspection. Previous research established that chlorophyll and related compounds, commonly found in feces and injury sites on plants, can be detected using fluorescent responses to UV excitation. In this study, a time-resolved multispectral imaging system was modified to allow hyperspectral line-scan imaging of fluorescent responses to 355-nm pulsed-laser excitation. Addition of a spectral adapter allowed acquisition of line images representing one spatial dimension with full spectral information for each spatial pixel location. Full-object images can be created by concatenating sequential line-scan images. For line-scan imaging, full-object illumination is inefficient. To better fit the illumination to the line-scan imaging field, laser line-expansion was achieved using a Powell lens. Illumination efficiency was 28.5% using the Powell lens compared to 3.0% using simple optical expansion. To test the modified system, spinach was inoculated with 1:2, 1:10, 1:100, and 1:200 dilutions of bovine manure. Using detection based on visual observation, a 100% detection rate was found for all dilutions. Automated detection rates using estimates of fluorescent decay were 100%, 100%, 100%, and 82 % for the 1:2, 1:10, 1:100, and 1:200 dilutions, respectively. These results suggest this technology has potential for the development of a commercial system for pre-harvest detection of fecal contamination and signs of animal intrusion.

A narrative examination of the governing scripts in the dreams and early recollections of women with eating disorders
Creators: name: Goldswain, Susan M.
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to examine the governing scripts in the lives of women with eating disorders via narrative analysis. Interviews were conducted with 5 women with eating disorders (EDs), whose ages ranged from 27 years to 36 years. An average of two interviews per participant took place, with each interview being recorded and transcribed. The interviews centred around early recollections (ERs) and dream reports, which were gathered in the context of their life-stories. The participants were recruited from private counselling practices, psychiatric practices, and family practices, and were considered suitable for the study if they expressed an interest in participating in the study, and their attending therapist or doctor was satisfied they fit the DSM-1V (APA, 1994) criteria for an eating disorder. Tomkins' (1979, 1987, 1991) script theory provided the theoretical underpinnings to the research, with Carlson's (1981, 1986) script-theoretic analysis as the primary methodological tool. Alexander's (1988) method of accessing scripts via principal identifiers of salience was used in conjunction with script-theoretic analysis when applicable. The ERs were examined for evidence of the nuclear scene, followed by analysis of the life-stories and dream stories for magnifications of the nuclear scene in the form of analogs and anti-analogs. The results showed the following commonalities: a) that a story of perceived loss of the parent or parental figure was at the heart of each nuclear scene, with the script threading through each woman's life as a theme of "longing for mother" or "a quest for love"; b) that the nuclear script was profoundly reactivated at the time of the development of each participant's ED; c) a family "no talk" rule about negative feelings and traumatic events; d) participants had difficult relationships with their mothers; e) a perception of home as unsafe, manifested in a recurring nightmare from childhood; f) participants responded to stress in their homes by adopting the personality of the "perfect girl" according to family values; g) body-image/self-image disturbances predated the eating disorder; and h) that traditional gender-roles and attitudes towards women were present in all the families in varying ways. More narrative research of the lives of women with EDs is needed to confirm and support these findings.

description: The vector vortex coronagraph is an instrument designed for direct detection and spectroscopy of exoplanets over a broad spectral range. Our team is working towards demonstrating contrast performance commensurate with imaging temperate, terrestrial planets orbiting solar-type stars using the High Contrast Imaging Testbed facility at NASA's Jet Propulsion Laboratory. To date, the best broadband performance achieved is $\sim$10$^{-8}$ raw contrast over a bandwidth of $Δλ/λ$=10\% in the visible regime (central wavelengths of 550-750 nm), while monochromatic tests yield much deeper contrast ($\sim$10$^{-9}$ or better). In this study, we analyze the main performance limitations on the testbeds so far, focusing on the quality of the focal plane mask manufacturing. We measure the polarization properties of the masks and the residual electric field in the dark hole as a function of wavelength. Our results suggest that the current performance is limited by localized defects in the in the focal plane masks. A new generation of masks is under test that have fewer defects and promise performance improvements.

description: We study phases of five-dimensional three-charge black holes with a circle in their transverse space. In particular, when the black hole is localized on the circle we compute the corrections to the metric and corresponding thermodynamics in the limit of small mass. When taking the near-extremal limit, this gives the corrections to the constant entropy of the extremal three-charge black hole as a function of the energy above extremality. For the partial extremal limit with two charges sent to infinity and one finite we show that the first correction to the entropy is in agreement with the microscopic entropy by taking into account that the number of branes shift as a consequence of the interactions across the transverse circle. Beyond these analytical results, we also numerically obtain the entire phase of non- and near-extremal three- and two-charge black holes localized on a circle. More generally, we find in this paper a rich phase structure, including a new phase of three-charge black holes that are non-uniformly distributed on the circle. All these three-charge black hole phases are found via a map that relates them to the phases of five-dimensional neutral Kaluza-Klein black holes.

description: Mechanical creep behaviors of natural gas hydrates (NGHs) are of importance for understanding mechanical instability of gas hydrate-bearing sediments on Earth. Limited by the experimental challenges, intrinsic creep mechanisms of nanocrystalline methane hydrates remain largely unknown yet at molecular scale. Herein, using large-scale molecular dynamics (MD) simulations, mechanical creep behaviors of nanocrystalline methane hydrates are investigated. It is revealed that mechanical creep responses are greatly dictated by internal microstructures of crystalline grain size and external conditions of temperature and static stress. Interestingly, a long steady-state creep is observed in nanocrystalline methane hydrates, which can be described by a modified constitutive Bird-Dorn-Mukherjee model. Microstructural analysis show that deformations of crystalline grains, grain boundary (GB) diffusion and GB sliding collectively govern the mechanical creep behaviors of nanocrystalline methane hydrates. Furthermore, structural transformation also appears important in their mechanical creep mechanisms. This study sheds new insights into understanding the mechanical creep scenarios of gas hydrates.

description: Substantial experimental, theoretical, as well as numerical effort has been invested to understand the effect of boundary slippage in microfluidic devices. However, even though such devices are becoming increasingly important in scientific, medical, and industrial applications, a satisfactory understanding of the phenomenon is still lacking. This is due to the extremely precise experiments needed to study the problem and the large number of tunable parameters in such systems. In this paper we apply a recently introduced algorithm to implement hydrophobic fluid-wall interactions in the lattice Boltzmann method. We find a possible explanation for some experiments observing a slip length depending on the flow velocity which is contradictory to many theoretical results and simulations. Our explanation is that a velocity dependent slip can be detected if the flow profile is not fully developed within the channel, but in a transient state. Further, we show a decrease of the measured slip length with increasing viscosity and demonstrate the effect of adding surfactant to a fluid flow in a hydrophobic microchannel. The addition of surfactant can shield the repulsive potential of hydrophobic walls, thus lowering the amount of slip with increasing surfactant concentration.

description: We study the heat transfer between two parallel metallic semi-infinite media with a gap in the nanometer-scale range. We show that the near-field radiative heat flux saturates at distances smaller than the metal skin depth when using a local dielectric constant and investigate the origin of this effect. The effect of non-local corrections is analysed using the Lindhard-Mermin and Boltzmann-Mermin models. We find that local and non-local models yield the same heat fluxes for gaps larger than 2 nm. Finally, we explain the saturation observed in a recent experiment as a manifestation of the skin depth and show that heat is mainly dissipated by eddy currents in metallic bodies.

description: Multipath routing is useful for networks to achieve load sharing among multiple routing paths. Multipath BGP (MBGP) is a technique to realize inter-domain multipath routing by enabling a BGP router to install multiple equally-good routes to a destination prefix. Most of previous works did not distinguish between intra-domain and inter-domain multipath routing. In this paper, we present a measurement study on the deployment of M-BGP in a large Internet service provider (ISP) network. Our method combines control-plane BGP measurements using Looking Glasses (LG), and data-plane traceroute measurements using RIPE Atlas. We focus on Hurricane Electric (AS6939) because it is a global ISP that connects with hundreds of major exchange points and exchanges IP traffic with thousands of different networks. And more importantly, we find that this ISP has by far the largest number of M-BGP deployments among autonomous systems with LG servers. Specifically, Hurricane Electric has deployed M-BGP with 512 of its peering ASes at 58 PoPs around the world, including many top ASes and content providers. We also observe that most of its M-BGP deployments involve IXP interconnections. Our work provides insights into the latest deployment of M-BGP in a major ISP network and it highlights the characteristics and effectiveness of M-BGP as a means to realize load sharing.

description: Using the Landau Fermi liquid theory we have discovered a new regime for the propagation of spin waves in a quasi-equilibrium spin systems. We have determined the dispersion relation for the transverse spin waves and found that one of the modes is gapless. The gapless mode corresponds to the precessional mode of the magnetization in a paramagnetic system in the absence of an external magnetic field. One of the other modes is gapped which is associated with the precession of the spin current around the internal field. The gapless mode has a quadratic dispersion leading to some interesting thermodynamic properties including a $T^{3/2}$ contribution to the specific heat. We also show that these modes make significant contributions to the dynamic structure function.

Conception of a higher power amongst recovering alcoholics

description: Historically, mainstream psychology has viewed spirituality as irrelevant and/or inappropriate material for non-religious counselling settings. With increasing recognition of constructivist research and a renewed interest in holistic counselling approaches, spirituality has become an acceptable topic for counselling research and is theorized to be a central factor in the development of wellness across the life span. However, spirituality has not been clearly defined, and no known study has been made of the ways in which people conceptualize a higher power. Working from within the constructivist paradigm, this study used phenomenographic techniques to arrive at categories of description which capture the qualitatively different ways in which recovering alcoholics understand and experience a higher power. Using purposeful sampling methods, a sample of seven women and men was drawn from the fellowship of Alcoholics Anonymous, a program which actively promotes reliance on a power greater than oneself but does not specify any particular conception of a higher power. During individual, audio-taped interviews, participants described concrete experiences which had in some way affected their conception of a higher power. The interviews were transcribed and analyzed, yielding seven qualitatively different ways of conceptualizing a higher power: as Vengeful Judge, as Human Fabrication, as Bird-Goddess, as Loving Father, as Spirit of Love, as Universal Order and as Everything. The conceptions describe not people, but the various ways in which people think about a higher power; individuals were found to shift from one conception to another over time, and in different circumstances. Viewed along a continuum, the conceptions reveal an increasing sense of connection with self, others and the infinite as the source of power is internalized and an intrinsic system of values is developed. The findings support recent theories suggesting that spirituality plays a central role in the development of wellness.
Consistency of the black hole mass determination in AGN from the reverberation and the X-ray excess variance method

description: Values of black hole masses are frequently determined with the help of the reverberation method. This method requires a specific geometrical factor related to the distribution of the orbits of the Broad Line Region clouds. Onken et al. determined the value f^2= 1.37+/-0.45 from the black hole mass - dispersion relation. In this paper we determine this factor using an independent mass determination from the X-ray variance method for a number of Seyfert 1 galaxies and comparing them with the reverberation results by Peterson et al. We obtain mean value f^2 = 1.12 +/- 0.54, consistent with Onken et al. Both values are larger than the value 0.75 corresponding to a spherical geometry. It indicates that most probably all values of the black hole masses obtained with the use of the Kaspi et al. formulae should be multiplied by a factor of \sim 1.7. This also shows that the Broad Line Region is rather flat, and hints for a dependence of the factor f^2 on a source inclination seem to be present in the data.

description: We establish a formula of the large N factorization of the modular S-matrix for the coupled representations in U(N) Chern-Simons theory. The formula was proposed by Aganagic, Neitzke and Vafa, based on computations involving the conifold transition. We present a more rigorous proof that relies on the universal character for rational representations and an expression of the modular S-matrix in terms of the specialization of characters.

description: Within the so-called "no-man's land" between about 150 and 235 K, crystallization of bulk water is inevitable. The glasslike freezing and a liquid-to-liquid transition of water, predicted to occur in this region, can be investigated by confining water in nanometer-sized pores. Here we report the molecular dynamics of water within the pores of a metal-organic framework using dielectric spectroscopy. The detected temperature-dependent dynamics of supercooled water matches that of bulk water as reported outside the borders of the no-man's land. In confinement, a different type of water is formed, nevertheless still undergoing a glass transition with considerable molecular cooperativity. Two different length scales seem to exist in water: A smaller one, of the order of 2 nm, being the cooperativity length scale governing glassy freezing, and a larger one (> 2 nm), characterizing the minimum size of the hydrogen-bonded network needed to create "real" water with its unique dynamic properties

description: We revisit the electromagnetic heat transfer between a metallic nanoparticle and a metallic semi-infinite substrate, commonly studied using the electric dipole approximation. For infrared and microwave frequencies, we find that the magnetic polarizability of the particle is larger than the electric one. We also find that the local density of states in the near field is dominated by the magnetic contribution. As a consequence, the power absorbed by the particle in the near field is due to dissipation by fluctuating eddy currents. These results show that a number of near-field effects involving metallic particles should be affected by the fluctuating magnetic fields.
