Study of Possible Local Quasars I: The First Sample

This study provides new arguments for the existence of local quasars, i.e. quasars in the vicinity of low redshift galaxies. Local quasars are probably ejected from respective parent galaxy. The sample includes 74 quasars in the vicinity of 8 different galaxies. Assuming for quasars the same distances from the observer, as for their respective parent galaxy, simple calculations lead to the quasars luminosities and radii. Furthermore, the assumption is made that the major part of redshifts of quasars are due to gravitational reddening, i.e. they are intrinsic in origin. In this way, data for masses and densities of quasars are obtained and a diagram Density-Redshift is constructed. Relationships are also found for: Abso- lute mag. - Radius, Absolute mag - Mass, Mass - Radius, and Mass - Luminosity for this sample of local quasars. Com- parison with the same diagrams for stars suggests a possible connection between stars and quasars. All these relationships are compelling evidence that the assumptions and the procedure in this study are correct. The relationships found imply that local quasars behave like single bodies, or at least the bulk of the quasar's mass is a single body, close to its gravita- tional radius. The theory of such strange bodies does not yet exist. Local quasars show signs of evolution: their redshifts decrease with time, as their densities decrease. The physics behind this evolution is not yet clear. However, yet unknown physical processes might be involved, which cause the ejection of quasars by active galactic nuclei and the subsequent disintegration of matter of quasars. The end-product of this evolution (disintegration) could be small-mass companion galaxies. A relation "mass - density" is found, which could be explained if the speed of evolution (disintegration) depends on the mass of the quasar: more massive quasars evolve more rapidly.
QUANTUM CALCULATION OF INELASTIC CO COLLISIONS WITH H. II. PURE ROTATIONAL QUENCHING OF HIGH ROTATIONAL LEVELS

Carbon monoxide is a simple molecule present in many astrophysical environments, and collisional excitation rate coefficients due to the dominant collision partners are necessary to accurately predict spectral line intensities and extract astrophysical parameters. We report new quantum scattering calculations for rotational deexcitation transitions of CO induced by H using the three-dimensional potential energy surface (PES) of Song et al. State-to-state cross sections for collision energies from 10−5 to 15,000 cm−1 and rate coefficients for temperatures ranging from 1 to 3000 K are obtained for CO (v = 0, j) deexcitation from j = 1 – 45 ? > to all lower j′ levels, where j is the rotational quantum number. Close-coupling and coupled-states calculations were performed in full-dimension for j = 1 – 5 ? > , 10, 15, 20, 25, 30, 35, 40, and 45 while scaling approaches were used to estimate rate coefficients for all other intermediate rotational states. The current rate coefficients are compared with previous scattering results using earlier PESs. Astrophysical applications of the current results are briefly discussed.
Search by Ideal Candidates: Next Generation of Talent Search at LinkedIn

One key challenge in talent search is how to translate complex criteria of a hiring position into a search query. This typically requires deep knowledge on which skills are typically needed for the position, what are their alternatives, which companies are likely to have such candidates, etc. However, listing examples of suitable candidates for a given position is a relatively easy job. Therefore, in order to help searchers overcome this challenge, we design a next generation of talent search paradigm at LinkedIn: Search by Ideal Candidates. This new system only needs the searcher to input one or several examples of suitable candidates for the position. The system will generate a query based on the input candidates and then retrieve and rank results based on the query as well as the input candidates. The query is also shown to the searcher to make the system transparent and to allow the searcher to interact with it. As the searcher modifies the initial query and makes it deviate from the ideal candidates, the search ranking function dynamically adjusts an refreshes the ranking results balancing between the roles of query and ideal candidates. As of writing this paper, the new system is being launched to our customers.
Creating and analyzing stereoscopic 3D graphical user interfaces in digital games

Creating graphical user interfaces (GUI) for stereoscopic 3D (S3D) games is a difficult choice between visual comfort and effect. We present a S3D Game GUI Design Space and a list of S3D-specific attributes that emphasizes integrating visually comfortable interfaces into the game world, story and S3D view. To showcase our approach, we created two GUI concepts and evaluated them with 32 users. Our results show quality improvements for a combination of bottom position and visual attachment for a menu. In a referencing interface, placing the reference near to the target depth significantly improved perceived quality, game integration, and increased presence. These results confirm the need to create S3D GUIs with perceptual constraints in mind, demonstrating the potential to extend the user experience. Additionally, our design space offers a formal and flexible way to create new effects in S3D GUIs.
CTL the language for describing core-based test

As part of an industry wide effort the IEEE is in the process of standardizing the elements of test technology such that plug & play can be achieved when testing SoC designs. This standard under development is a language namely, Core Test Language (CTL), which is introduced in this paper. CTL describes all necessary information for test pattern reuse and the needs of test during system integration. CTL syntax and its link to STIL are explained with examples.
Web image mining towards universal age estimator

In this paper, we present an automatic web image mining system towards building a universal human age estimator based on facial information, which is applicable to all ethnic groups and various image qualities. First, a large (<391k) yet noisy human aging image dataset is crawled from the photo sharing website Flickr and Google image search engine based on a set of human age related text queries. Then, within each image, several human face detectors of different implementations are used for robust face detection, and all the detected faces with multiple responses are considered as the multiple instances of a bag (image). An outlier removal step with Principal Component Analysis further refines the image set to about 220k faces, and then a robust multi-instance regressor learning algorithm is proposed to learn the kernel-regression based human age estimator under the scenarios with possibly noisy bags. The proposed system has the following characteristics: 1) no manual human age labeling process is required, and the age information is automatically obtained from the age related queries, 2) the derived human age estimator is universal owing to the diversity and richness of Internet images and thus has good generalization capability, and 3) the age estimator learning process is robust to the noises existing in both Internet images and corresponding age labels. This automatically derived human age estimator is extensively evaluated on three popular benchmark human aging databases, and without taking any images from these benchmark databases as training samples, comparable age estimation accuracies with the state-of-the-art results are achieved.
Learnings Options End-to-End for Continuous Action Tasks

We present new results on learning temporally extended actions for continuoustasks, using the options framework (Suttonet al.[1999b], Precup [2000]). In orderto achieve this goal we work with the option-critic architecture (Baconet al.[2017])using a deliberation cost and train it with proximal policy optimization (Schulmanet al.[2017]) instead of vanilla policy gradient. Results on Mujoco domains arepromising, but lead to interesting questions aboutwhena given option should beused, an issue directly connected to the use of initiation sets.
Free field representation of Toda field theories

We study the following problem: Can a classical sln Toda field theory be represented by means of free bosonic oscillators through a Drinfeld-Sokolov construction? We answer affirmatively in the case of a cylindrical space-time and for real hyperbolic solutions of the Toda field equations. We establish in fact a one-to-one correspondence between such solutions and the space of free left and right bosonic oscillators with coincident zero modes. We discuss the same problem for real singular solutions with nonhyperbolic monodromy.
Economic hardship after retirement age Economic Hardship Among Older People in New Zealand : The Effects of Low Living Standards on Social Support , Loneliness , and Mental Health

B 2026 it has been estimated that people aged 65 and over will make up approximately 20% of the population of New Zealand (Statistics New Zealand, 2005). These demographic changes, which reflect international trends, call for reconsideration of the conventional ways of understanding decrements in mental health and cognitive functioning as part of an inevitable decline in older age. In response to increases in life expectancy and rapid increase in the older population, social policy has shifted toward a focus on ‘positive ageing’ and an interest in addressing the factors that will affect wellbeing in older age. One important aspect of wellbeing is mental health. Mental illnesses, including anxiety and depression as well as dementia and psychiatric disorders are “widespread among the elderly in OECD countries and can lead to entry into institutional care” (Oxley, 2009). Alarmingly, of 10 OECD countries, New Zealand has been shown to be second only to the USA in lifetime prevalence of mental health disorders (Chapple & Ladaique, 2009). From a population health perspective, two important aspects of people’s social lives have been shown to be reliably related to their mental health are economic hardship (Wilkinson, 2005) or poverty (Belle, 1990) and social support (Berkman, 2000) or loneliness (Cornwell & Waite, 2009. The social position of older people in our societies puts them at risk for both poorer economic well-being and lower social support or more loneliness, compared to the rest of the population. Thus, experiences of old age include risk of poorer mental health, lower social support, and increased poverty and these are not experienced separately by elders, but have intertwined effects which we will explore in this paper.
Vehicle Speed Detecting App

The report presents the measurement of vehicular speed using a smartphone camera. The speed measurement is accomplished by detecting the position of the vehicle on a camera frame using the LBP cascade classifier of OpenCV API, the displacement of the detected vehicle with time is used to compute the speed. Conversion coefficient is determined to map the pixel displacement to actual vehicle distance. The speeds measured are proportional to the ground truth speeds.
Environmental factors regulate Paneth cell phenotype and host susceptibility to intestinal inflammation in Irgm1-deficient mice

ABSTRACT Crohn's disease (CD) represents a chronic inflammatory disorder of the intestinal tract. Several susceptibility genes have been linked to CD, though their precise role in the pathogenesis of this disorder remains unclear. Immunity-related GTPase M (IRGM) is an established risk allele in CD. We have shown previously that conventionally raised (CV) mice lacking the IRGM ortholog, Irgm1 exhibit abnormal Paneth cells (PCs) and increased susceptibility to intestinal injury. In the present study, we sought to utilize this model system to determine if environmental conditions impact these phenotypes, as is thought to be the case in human CD. To accomplish this, wild-type and Irgm1−/− mice were rederived into specific pathogen-free (SPF) and germ-free (GF) conditions. We next assessed how these differential housing environments influenced intestinal injury patterns, and epithelial cell morphology and function in wild-type and Irgm1−/− mice. Remarkably, in contrast to CV mice, SPF Irgm1−/− mice showed only a slight increase in susceptibility to dextran sodium sulfate-induced inflammation. SPF Irgm1−/− mice also displayed minimal abnormalities in PC number and morphology, and in antimicrobial peptide expression. Goblet cell numbers and epithelial proliferation were also unaffected by Irgm1 in SPF conditions. No microbial differences were observed between wild-type and Irgm1−/− mice, but gut bacterial communities differed profoundly between CV and SPF mice. Specifically, Helicobacter sequences were significantly increased in CV mice; however, inoculating SPF Irgm1−/− mice with Helicobacter hepaticus was not sufficient to transmit a pro-inflammatory phenotype. In summary, our findings suggest the impact of Irgm1-deficiency on susceptibility to intestinal inflammation and epithelial function is critically dependent on environmental influences. This work establishes the importance of Irgm1−/− mice as a model to elucidate host-environment interactions that regulate mucosal homeostasis and intestinal inflammatory responses. Defining such interactions will be essential for developing novel preventative and therapeutic strategies for human CD. Summary: In this study, we rederived conventionally raised Irgm1-deficient mice into specific pathogen-free and germ-free conditions. We show that these environments determine how Irgm1 regulates Paneth cell function and gut inflammation susceptibility.
Nuclear respiratory factor 2 induces SIRT3 expression

The mitochondrial deacetylase SIRT3 regulates several important metabolic processes. SIRT3 is transcriptionally upregulated in multiple tissues during nutrient stresses such as dietary restriction and fasting, but the molecular mechanism of this induction is unclear. We conducted a bioinformatic study to identify transcription factor(s) involved in SIRT3 induction. Our analysis identified an enrichment of binding sites for nuclear respiratory factor 2 (NRF‐2), a transcription factor known to play a role in the expression of mitochondrial genes, in the DNA sequences of SIRT3 and genes with closely correlated expression patterns. In vitro, knockdown or overexpression of NRF‐2 modulated SIRT3 levels, and the NRF‐2α subunit directly bound to the SIRT3 promoter. Our results suggest that NRF‐2 is a regulator of SIRT3 expression and may shed light on how SIRT3 is upregulated during nutrient stress.
Hybrid Queries over Symbolic and Spatial Trajectories: A Usage Scenario

Symbolic trajectories is a novel data model recently proposed for the modeling and querying of temporally annotated sequences of symbolic descriptions, representing e.g. transportation means, places of interest, and so forth. Unlike geometric trajectories, symbolic trajectories capture the thematic dimension of movement. In this demonstration, we illustrate a practical approach to the querying of hybrid trajectories, combining the symbolic and geometric dimension in a multidimensional trajectory. The system runs on the Secondo moving object database. The multi-dimensional trajectories are obtained from the GeoLife dataset.
Split-Gate Logic circuits for multi-threshold technologies

A new dual-Vt static CMOS circuits, the Split-Gate dual-Vt (SG-DVT) logic, are devised. Their performance is compared to that of all-low-Vt, all-high-Vt, and other dual-Vt circuits in terms of speed and energy consumption (both static and dynamic). They achieved speeds close to that of the all-low-Vt circuits, lower leakage (both stand-by and active) than other dual-Vt circuits, and lower leakage dependency on logic block input patterns.
Capacity Bounds for a Class of Interference Relay Channels

The capacity of a class of interference relay channels (IRCs)-the injective semideterministic IRC where the relay can only observe one of the sources-is investigated. We first derive a novel outer bound and two inner bounds which are based on a careful use of each of the available cooperative strategies together with the adequate interference decoding technique. The outer bound extends Telatar and Tse's work, whereas the inner bounds contain several known results in the literature. Our main result is the characterization of the capacity region of the Gaussian class of IRCs studied within a fixed number of bits per dimension, constant gap. The proof relies on the use of the different cooperative strategies in specific SNR regimes due to their complexity. As a matter of fact, this issue reveals the complex nature of the Gaussian IRC where the combination of a single coding scheme for the Gaussian relay and interference channel may not lead to a good coding scheme for this problem, even when the focus is only on capacity within a constant gap over all possible fading statistics.
Towards a model of story puns

There is a class of joke which consists of an anecdote, which is sometimes quite long and often has no inherently humorous content, followed by a final line which is a distorted form of some well-known phrase, proverb or quotation. Usually this final line purports to summarize or draw a moral from the preceding story. This genre has some unusual aspects, from the viewpoint of conventional claims about the attributes of jokes. These jokes also have certain structural or formal regularities, which suggest that it might be possible to define a computational model of their production. We outline how this might be done, by decomposing the construction of such story puns into a sequence of stages; some of these are clearly manageable, others are less straightforward. We also make some observations about where such an endeavor would fit within the broader field of humor research.
NMR Shielding in Metals Using the Augmented Plane Wave Method

We present calculations of solid state NMR magnetic shielding in metals, which includes both the orbital and the complete spin response of the system in a consistent way. The latter contains an induced spin-polarization of the core states and needs an all-electron self-consistent treatment. In particular, for transition metals, the spin hyperfine field originates not only from the polarization of the valence s-electrons, but the induced magnetic moment of the d-electrons polarizes the core s-states in opposite direction. The method is based on DFT and the augmented plane wave approach as implemented in the WIEN2k code. A comparison between calculated and measured NMR shifts indicates that first-principle calculations can obtain converged results and are more reliable than initially concluded based on previous publications. Nevertheless large k-meshes (up to 2 000 000 k-points in the full Brillouin-zone) and some Fermi-broadening are necessary. Our results show that, in general, both spin and orbital components of the NMR shielding must be evaluated in order to reproduce experimental shifts, because the orbital part cancels the shift of the usually highly ionic reference compound only for simple sp-elements but not for transition metals. This development paves the way for routine NMR calculations of metallic systems.
Early Detection of Amyloidopathy in Alzheimer's Mice by Hyperspectral Endoscopy.

PURPOSE To describe a spectral imaging system for small animal studies based on noninvasive endoscopy of the retina, and to present time-resolved spectral changes from live Alzheimer's mice prior to cognitive decline, corroborating our previous in vitro findings. METHODS Topical endoscope fundus imaging was modified to use a machine vision camera and tunable wavelength system for acquiring monochromatic images across the visible to near-infrared spectral range. Alzheimer's APP/PS1 mice and age-matched, wild-type mice were imaged monthly from months 3 through 8 to assess changes in the fundus reflection spectrum. Optical changes were fit to Rayleigh light scatter models as measures of amyloid aggregation. RESULTS Good quality spectral images of the central retina were obtained. Short-wavelength reflectance from Alzheimer's mice retinae showed significant reduction over time compared to wild-type mice. Optical changes were consistent with an increase in Rayleigh light scattering in neural retina due to soluble Aβ1-42 aggregates. The changes in light scatter showed a monotonic increase in soluble amyloid aggregates over a 6-month period, with significant build up occurring at 7 months. CONCLUSIONS Hyperspectral imaging technique can be brought inexpensively to the study of retinal changes caused by Alzheimer's disease progression in live small animals. A similar previous finding of reduction in the light reflection over a range of wavelengths in isolated Alzheimer's mice retinae, was reproducible in the living Alzheimer's mice. The technique presented here has a potential for development as an early Alzheimer's retinal diagnostic test in humans, which will support the treatment outcome.
Prototype 250 GHz Bandwidth Chip to Chip Electrical Interconnect, Characterized With Ultrafast Optoelectronics

We have connected two optoelectronic chips with air-spaced two-wire transmission lines and have observed essentially undistorted transmission of 1.8 ps (FWHM) electrical pulses over propagation distances up to 200 cm. The lines consist of two 0.4 mm (or 0.5 mm) diameter copper wires with centers separated by 1.0 mm. The air spaced two-wire lines show transform-limited TEM mode pulse propagation with very small group velocity dispersion (GVD), and relatively low attenuation. Our achieved performance with a power loss of 5.8 dB/m approaches that needed for mm-wave and THz interconnects. The coupling was enabled by two tungsten probes with 1 μm diameter tips in near-contact (5 μm gap) with the coplanar transmission lines on the transmitting and receiving optoelectronic chips. The air spaced two-wire line's relatively small, measured pulse amplitude attenuation coefficient was 1.31 times larger than the theoretical prediction for the TEM mode. This discrepancy is considered to be primarily due to reduction of the Cu conductivity in the THz skin-depth layer.
Using Verb Subcategorization for Word Sense Disambiguation

We develop a model for predicting verb sense from subcategorization information and integrate it into SSI-Dijkstra, a wide-coverage knowledge-based WSD algorithm. Adding syntactic knowledge in this way should correct the current poor performance of WSD systems on verbs. This paper also presents, for the first time, an evaluation of SSI-Dijkstra on a standard data set which enables a comparison of this algorithm with other knowledge-based WSD systems. Our results show that our system is competitive with current graph-based WSD algorithms, and that the subcategorization model can be used to achieve better verb sense disambiguation performance.
Topography and scale in a community-driven maternal and child health program in Eastern Indonesia

In 2007, the Indonesian government introduced Generasi, a community-driven development program to address village priorities such as reducing poverty, maternal mortality, and child mortality. When describing Generasi’s biggest challenges, program facilitators on the eastern Indonesian island of Flores used a geographic vocabulary of fields (medan, lapangan) and topography (topografi) that evokes the demands of supervising Generasi’s implementation across dozens of mountain villages with poor infrastructure. But their geographic language also extends metaphorically to the enduring problems of scale and governance. I analyze these discourses of topography and field in relation to the changing therapeutic landscape of maternal and child health services in the Manggarai highlands of western Flores, then follow Generasi’s scalar scaffolding from the meetings and clinics in villages, to the technocratic policy work in Jakarta, and to the academic spaces of Auckland and Cambridge.
