High-speed Motion Analysis with Multi-Exposure Images

We propose a method to estimate dense motion vector fields from multi-exposure images. Our approach relies on finding a sparse set of correspondences between features in a single-exposure image and each exposure in a multi-exposure image using a global optimization technique. We iteratively establish such matches, compute a set of locally restricted transformations for the matches, and construct a dense motion vector field in a multiresolution framework. The estimation of the number of necessary transformations and the regions of influence is guided by superpixel segmentation of the image. We present results for multi-exposure photos of different dynamic scenes.
Player Modeling

Player modeling is the study of computational models of players in games. This includes the detection, modeling, prediction and expression of human player characteristics which are manifested through cognitive, aﬀective and behavioral patterns. This chapter introduces a holistic view of player modeling and provides a high level taxonomy and discussion of the key components of a player’s model. The discussion focuses on a taxonomy of approaches for constructing a player model, the available types of data for the model’s input and a proposed classiﬁcation for the model’s output. The chapter provides also a brief overview of some promising applications and a discussion of the key challenges player modeling is currently facing which are linked to the input, the output and the computational model.
The complete mitochondrial genome of the Rhodeus shitaiensis (Teleostei, Cypriniformes, Acheilognathidae)

Abstract The complete mitochondrial genome of the Rhodeus shitaiensis was determined by using a PCR-based method. The total length of mitochondrial DNA of this bitterling is 16,774 bp and includes 13 protein-coding genes, 2 ribosomal RNA, 22 transfer RNA genes, 1 replication origin region and 1 control region. The mitochondrial gene arrangement of the R. shitaiensis is also matching the one observed in the most vertebrate creatures. Base composition of the genome is A (28.7%), T (26.5%), C (27.4%) and G (17.4%) with an A + T rich hallmark as that of other vertebrate mitochondrial genomes.
Mail2Wiki: low-cost sharing and early curation from email to wikis

In this design paper we motivate and describe the Mail2Wiki system, which enables low-cost sharing and early curation from email to wikis by knowledge workers. We aim to aid adoption of enterprise wikis and enable more efficient knowledge sharing and reuse. We present a design rationale grounded in prior empirical work, the design of the system, and the evaluation of the user interface. The system includes two alternative front-ends to enable incremental adoption by workers who are currently using email to share with their communities.
Variations in near‐surface debris temperature through the summer monsoon on Khumbu Glacier, Nepal Himalaya

Debris surface temperature is a function of debris characteristics and energy fluxes at the debris surface. However, spatial and temporal variability in debris surface temperature, and the debris properties that control it, are poorly constrained. Here, near‐surface debris temperature (Ts) is reported for 16 sites across the lower elevations of Khumbu Glacier, Nepal Himalaya, for the 2014 monsoon season. The debris layer at all sites was ≥1 m thick. We confirm the occurrence of temporal and spatial variability in Ts over a 67‐day period and investigate its controls. Ts was found to exhibit marked temporal fluctuations on diurnal, short‐term (1–8 days) and seasonal timescales. Over the study period, two distinct diurnal patterns in Ts were identified that varied in timing, daily amplitude and maximum temperature; days in the latter half of the study period (after Day of Year 176) exhibited a lower diurnal amplitude (mean = 23°C) and reduced maximum temperatures. Days with lower amplitude and minimum Ts were concurrent with periods of increased seasonal variability in on‐glacier air temperature and incoming shortwave radiation, with the increased frequency of these periods attributed to increasing cloud cover as the monsoon progressed. Spatial variability in Ts was manifested in variability of diurnal amplitude and maximum Ts of 7°C to 47°C between sites. Local slope, debris clast size and lithology were identified as the most important drivers of spatial variability in Ts, with inclusion of these three variables in the stepwise general linear models resulting in R2 ≥0.89 for six out of the seven sites. The complexity of surface energy fluxes and their influence on Ts highlight that assuming a simplified relationship between air temperature and debris surface temperature in glacier melt models, and a direct relationship between debris surface temperature and debris thickness for calculating supraglacial debris thickness, should be undertaken with caution. © 2018 The Authors.

New conditions for the convergence of H∞ filters and predictors

The finite-horizon H/sub /spl infin// filtering and prediction problems in the discrete-time case admit solutions only if a suitable difference Riccati equation is solved by a matrix sequence satisfying "feasibility" conditions. In this work, sufficient conditions ensuring the existence of filters and predictors over an arbitrarily long time interval are derived. Moreover, it is shown that, under these conditions, finite horizon estimators tend to stable stationary ones as the time horizon increases.
Gonadotropin secretion during prolonged hyperprolactinemia: basal secretion and the stimulatory feedback effect of estrogen.

Inoculation of cyclic female rats with the prolactin (Prl)/growth hormone-secreting pituitary tumor, MtT.W15, resulted in a cessation of estrous cyclicity within 5--10 days. Associated with this acyclicity was a persistently low serum concentration of estradiol and marked increases in both circulating Prl and progesterone. At Day 26 of acyclicity, basal serum luteinizing hormone (LH) values measured in samples taken every 20 min from 0900--1100 h were significantly reduced when compared to cyclic, nontumor animals on diestrus Day 2. There was no difference in basal follicle-stimulating hormone (FSH) concentrations. In a separate group of acyclic, tumor-bearing females 42--56 days after transplantation, a single s.c. injection of 20 micrograms estradiol benzoate (EB) at 1030 h elicited significant increases in both serum LH and FSH values between 1700 and 1830 h on the next day. The magnitude of the LH surge was reduced and that of FSH was increased in tumor-bearing animals when compared to cyclic, nontumor females given a similar EB injection on diestrus Day 1. These results demonstrate that chronic hyperprolactinemia is associated with inhibition of basal LH secretion and ovarian estrogen production and an increase in circulating progesterone concentrations. Nevertheless, the stimulatory feedback effects of estrogen on LH and FSH release are still present and functioning in acyclic female rats under chronically hyperprolactinemic conditions. These data suggest that the cessation of regular ovulatory cycles associated with hyperprolactinemia may be due to a deficiency of LH and/or estrogen secretion, but not to a lack of central nervous system response to the stimulatory feedback action of estrogen.
Hacia el inventario de flujos de carbono en aguas tropicales: unificar métodos

Recientemente se ha revalorado la relevancia de los sistemas acuaticos epicontinentales en el ciclo global del carbono, ya que estos tienen una gran capacidad de ser tanto sumideros de carbono, hacia sus sedimentos, como fuentes de carbono atmosferico. Sin embargo, la informacion acerca de los sistemas tropicales es aun heterogenea y escasa, situacion particularmente critica, dado que estos sistemas enfrentan problemas crecientes en el panorama del cambio global, contaminacion y eutrofizacion incluidas, particularmente esta ultima, asi como impactos de las estrategias de manejo (e.g., cambios en el nivel de agua). El estudio de la dinamica del oxigeno, criticado en el pasado, ha sido retomado y hoy es nuevamente utilizado ampliamente para estimar la produccion primaria y la respiracion ecosistemica ante la urgencia por estimar los flujos de carbono asociados a los sistemas acuaticos. Se revisan aqui, por ello, los aspectos metodologico-conceptuales asociados a la implementacion moderna del metodo de evolucion del oxigeno y se discuten las ventajas y los problemas asociados a esta metodologia, para facilitar y extender su aplicacion a los sistemas tropicales, donde su implementacion es muy conveniente. Se propone tambien una secuencia metodologica unificadora para hacer posible la comparacion entre estudios, y el escalamiento de los flujos de carbono, tanto espacial como temporalmente. Los inventarios de carbono en diferentes escalas (espaciales y temporales) son necesarios para entender la participacion y las respuestas de los sistemas acuaticos y regiones tropicales (en particular su papel como fuentes o sumideros de carbono) frente al cambio global.
Automatic Gait Motion Capture with Missing-Marker Fillings

Although marker-based optical motion capture has been a useful method for computer animation during the past decades, automatic and robust motion tracking from multiple video sequences is still very challenging. Several critical issues in practical implementations are not adequately addressed. For example, how to track and identify the reconstructed 3D points after image matching process? How to handle the heavy occlusion problem? This paper gives a careful investigation of the above issues. In particular, we propose a novel way to track and identify proper markers, and a new method of filling missing markers by taking account of the human model constraints. Experiments are presented to show its accuracy and robustness.
Genus distributions of iterated 3-wheels and 3-prisms

The iterated 3-prism P r 3 n is the cartesian product C 3 □ P n of a 3-cycle and an path. At each end of the iterated 3-prism, there is a 3-cycle whose vertices are 3-valent in C 3 □ P n . The iterated 3-wheel W 3 n is obtained by contracting one of these 3-cycles in C 3 □ P n + 1 to a single vertex. Using rooted-graphs , we derive simultaneous recursions for the partitioned genus distributions of W 3 n and a formula for the genus distribution of the graphs P r 3 n . A seemingly straightforward way to construct either the sequence of iterated prisms P r 3 n or the sequence of iterated wheels W 3 n , would be by iterative amalgamation of a copy of C 3 □ K 2 , such that a copy of C 3 contained in it is matched to the “newest” copy of C 3 in the growing graph. Calculating genus distributions for the sequences would then involve an excessively large set of simultaneous recurrences. To avoid this, we propose a method of iterative surgery, under which the same vertex is considered a root-vertex in all graphs of the sequence, and in which the successive calculations of genus distributions require only four simultaneous recurrences. We also prove that the genus distribution of P r 3 n not only dominates the genus distribution of W 3 n − 1 , but is also dominated by the genus distribution of W 3 n .
Deep sparse representation for robust image registration

The definition of the similarity measure is an essential component in image registration. In this paper, we propose a novel similarity measure for registration of two or more images. The proposed method is motivated by that the optimally registered images can be deeply sparsified in the gradient domain and frequency domain, with the separation of a sparse tensor of errors. One of the key advantages of the proposed similarity measure is its robustness to severe intensity distortions, which widely exist on medical images, remotely sensed images and natural photos due to the difference of acquisition modalities or illumination conditions. Two efficient algorithms are proposed to solve the batch image registration and pair registration problems in a unified framework. We validate our method on extensive challenging datasets. The experimental results demonstrate the robustness, accuracy and efficiency of our method over 9 traditional and state-of-the-art algorithms on synthetic images and a wide range of real-world applications.
Object Search and Localization for an Indoor Mobile Robot

In this paper we present a method for search and localization of objects with a mobile robot using a monocular camera with zoom capabilities. We show how to overcome the limitations of low resolution images in object recognition by utilizing a combination of an attention mechanism and zooming as the first steps in the recognition process. The attention mechanism is based on receptive field cooccurrence histograms and the object recognition on SIFT feature matching. We present two methods for estimating the distance to the objects which serve both as the input to the control of the zoom and the final object localization. Through extensive experiments in a realistic environment, we highlight the strengths and weaknesses of both methods. To evaluate the usefulness of the method we also present results from experiments with an integrated system where a global sensing plan is generated based on view planning to let the camera cover the space on a per room basis.
A character-level sequence-to-sequence method for subtitle learning

This paper presents a character-level sequence-to-sequence learning method, RNNembed. Specifically, we embed a Recurrent Neural Network (RNN) into an encoder-decoder framework and generate character-level sequence representation as input. The dimension of input feature space can be significantly reduced as well as avoiding the need to handle unknown or rare words in sequences. In the language model, we improve the basic structure of a Gated Recurrent Unit (GRU) by adding an output gate, which is used for filtering out unimportant information involved in the attention scheme of the alignment model. Our proposed method was examined in a large-scale dataset on a task of English-to-Chinese translation. Experimental results demonstrate that the proposed approach achieves a translation performance comparable, or close, to conventional word-based and phrase-based systems.
Effects of profilin and profilactin on actin structure and function in living cells

Previous studies have yielded conflicting results concerning the physiological role of profilin, a 12-15-kD actin- and phosphoinositide- binding protein, as a regulator of actin polymerization. We have addressed this question by directly microinjecting mammalian profilins, prepared either from an E. coli expression system or from bovine brain, into living normal rat kidney (NRK) cells. The microinjection causes a dose-dependent decrease in F-actin content, as indicated by staining with fluorescent phalloidin, and a dramatic reduction of actin and alpha-actinin along stress fibers. In addition, it has a strong inhibitory effect toward the extension of lamellipodia. However, the injection of profilin causes no detectable perturbation to the cell- substrate focal contact and no apparent depolymerization of filaments in either the nonlamellipodial circumferential band or the contractile ring of dividing cells. Furthermore, cytokinesis of injected cells occurs normally as in control cells. In contrast to pure profilin, high- affinity profilin-actin complexes from brain induce an increase in total cellular F-actin content and an enhanced ruffling activity, suggesting that the complex may dissociate readily in the cell and that there may be multiple states of profilin that differ in their ability to bind or release actin molecules. Our results indicate that profilin and profilactin can function as effective regulators for at least a subset of actin filaments in living cells.
Selecting an appropriate scheduler for use with time-triggered embedded systems

We have previously described a “language” consisting of more than seventy patterns. This language is intended to support the development of reliable embedded systems: the particular focus of the collection is on systems with a time triggered (TT) system architecture. We have been assembling this collection for a decade. As our experience with the collection has grown, we have begun to add a number of new patterns and revised some of the existing ones. As we have worked with this collection, we have felt that there were ways in which the overall architecture could be improved in order to make the collection easier to use, and to reduce the impact of future changes. The introduction to this paper describes the approach that we have taken in order to refactor and refine our original pattern collection. The core of the paper then goes on to describe one new pattern that has resulted from this process.

ThinSight

ThinSight is a thin form-factor interactive surface technology based on optical sensors embedded inside a regular liquid crystal display (LCD). These augment the display with the ability to sense a variety of objects near the surface, including fingertips and hands, to enable multitouch interaction. Optical sensing also allows other physical items to be detected, allowing interactions using various tangible objects. A major advantage of ThinSight over existing camera and projector-based systems is its compact form-factor, making it easier to deploy in a variety of settings. We describe how the ThinSight hardware is embedded behind a regular LCD, allowing sensing without degradation of dis- play capability, and illustrate the capabilities of our system through a number of proof-of-concept hardware prototypes and applications.
TACLeBench: A Benchmark Collection to Support Worst-Case Execution Time Research

Engineering related research, such as research on worst-case execution time, uses experimentation to evaluate ideas. For these experiments we need example programs. Furthermore, to make the research experimentation repeatable those programs shall be made publicly available. We collected open-source programs, adapted them to a common coding style, and provide the collection in open-source. The benchmark collection is called TACLeBench and is available from GitHub in version 1.9 at the publication date of this paper. One of the main features of TACLeBench is that all programs are self-contained without any dependencies on standard libraries or an operating system.
Seismic Evidence for Plume‐ and Craton‐Influenced Upper Mantle Structure Beneath the Northern Malawi Rift and the Rungwe Volcanic Province, East Africa

P and S wave tomographic models have been developed for the northern Malawi rift and adjacent Rungwe Volcanic Province (RVP) using data from the Study of Extension and maGmatism in Malawi aNd Tanzania project and data from previous networks in the study area. The main features of the models are a low‐velocity zone (LVZ) with δVp = ~−1.5–2.0% and δVs = ~−2–3% centered beneath the RVP, a lower‐amplitude LVZ (δVp = ~−1.0–1.3% and δVs = ~−0.7–1%) to the southeast of the RVP beneath the center and northeastern side of the northern Malawi rift, a shift of the lower‐amplitude anomaly at ~−10° to −11° to the west beneath the central basin and to the western side of the rift, and a fast anomaly at all depths beneath the Bangweulu Craton. The LVZ widens further at depths >~150–200 km and extends to the north beneath northwestern Malawi, wrapping around the fast anomaly beneath the craton. We attribute the LVZ beneath the RVP and the northern Malawi rift to the flow of warm, superplume mantle from the southwest, upwelling beneath and around the Bangweulu Craton lithosphere, consistent with high 3He/4He values from the RVP. The LVZ under the RVP and northern Malawi rift strongly indicates that the rifted lithosphere has been thermally perturbed. Given that volcanism in the RVP began about 10 million years earlier than the rift faulting, thermal and/or magmatic weakening of the lithosphere may have begun prior to the onset of rifting.
Response of six cultivars of cowpea (vigna unguiculata(l.) walp) to spent engine oil

Laboratory studies were carried out in 2008 at the Plant and Soil laboratory of the Faculty of Agriculture, Delta State University, Asaba Campus, Delta State, Nigeria to investigate the response of six cultivars (IT81D-699, 1T82 (e-18), IT84S-2246-4, TVx3236, IT90K-277-2 and IT870-94-1) of cowpea to spent engine oil. Seeds of the six cultivars of cowpea were presoaked in water for 24 hours and thereafter, soaked in spent engine oil for varying hours (0, 1, 2, 4, 8 and 16). Other seeds were soaked in the oil for 0, 1, 2, 3 and 4 days before germinated in Petri dishes lined with moist tissue paper. The results showed that the percentage germination, days to germination and rate of germination of the cowpea cultivars were both periods of seed soaking in oil and cultivar dependent. The results also showed that the longer the hours of seed presoaking in the oil, the poorer the germination response of the seeds. No germination occurred while seeds were still in the oil. TVx3236 followed by IT84S-2246-4 were more tolerant among the cowpea cultivars examined hence could be considered for phytoremediation practice in oil producing areas of the Niger Delta.
Cosmological parameters from lensed supernovae

We investigate the possibility of measuring the Hubble constant, the fractional energy density components and the equation of state parameter of the "dark energy" using lensed multiple images of high-redshift supernovae. With future instruments, such as the SNAP and NGST satellites, it will become possible to observe several hundred lensed core-collapse supernovae with multiple images. Accurate measurements of the image separation, flux-ratio, time-delay and lensing foreground galaxy will provide complementary information to the cosmological tests based on, e.g., the magnitude-redshift relation of type Ia supernovae, especially with regards to the Hubble parameter that could be measured with a statistical uncertainty at the one percent level. Assuming a flat universe, the statistical uncertainty on the mass density is found to be stat M < 0:05. However, systematic eects from the uncertainty of the lens modeling are likely to dominate. E.g., if the lensing galaxies are extremely compact but are (erroneously) modeled as singular isothermal spheres, the mass density is biased by syst M 0:1. We argue that wide-field near-IR instruments such as the one proposed for the SNAP mission are critical for collecting large statistics of lensed supernovae.
