Bundle Adjustment for Multi-Camera Systems with Points at Infinity

Abstract. We present a novel approach for a rigorous bundle adjustment for omnidirectional and multi-view cameras, which enables an efficient maximum-likelihood estimation with image and scene points at infinity. Multi-camera systems are used to increase the resolution, to combine cameras with different spectral sensitivities (Z/I DMC, Vexcel Ultracam) or – like omnidirectional cameras – to augment the effective aperture angle (Blom Pictometry, Rollei Panoscan Mark III). Additionally multi-camera systems gain in importance for the acquisition of complex 3D structures. For stabilizing camera orientations – especially rotations – one should generally use points at the horizon over long periods of time within the bundle adjustment that classical bundle adjustment programs are not capable of. We use a minimal representation of homogeneous coordinates for image and scene points. Instead of eliminating the scale factor of the homogeneous vectors by Euclidean normalization, we normalize the homogeneous coordinates spherically. This way we can use images of omnidirectional cameras with single-view point like fisheye cameras and scene points, which are far away or at infinity. We demonstrate the feasibility and the potential of our approach on real data taken with a single camera, the stereo camera FinePix Real 3D W3 from Fujifilm and the multi-camera system Ladybug 3 from Point Grey.
Low-Dimensional Shaping for High-Dimensional Lattice Codes

We propose two low-complexity lattice code constructions that have competitive coding and shaping gains. The first construction, named systematic Voronoi shaping, maps short blocks of integers to the dithered Voronoi integers, which are dithered integers that are uniformly distributed over the Voronoi region of a low-dimensional shaping lattice. Then, these dithered Voronoi integers are encoded using a high-dimensional lattice retaining the same shaping and coding gains of lowand high-dimensional lattices. A drawback to this construction is that there is no isomorphism between the underlying message and the lattice code, preventing its use in applications such as compute-and-forward. Therefore, we propose a second construction, called mixed nested lattice codes, in which a high-dimensional coding lattice is nested inside a concatenation of low-dimensional shaping lattices. This construction not only retains the same shaping/coding gains as first construction but also provides the desired algebraic structure. We numerically study these methods, for point-to-point channels as well as compute-and-forward using low-density lattice codes as coding lattices and E8 and Barnes-Wall as shaping lattices. Numerical results indicate a shaping gain of up to 0.86 dB, compared with the state-ofthe-art of 0.4 dB; furthermore, the proposed method has lower complexity than the state-of-the-art approaches.
Probing in Vivo Metabolism by Stable Isotope Labeling of Storage Lipids and Proteins in Developing Brassica napusEmbryos1

Developing embryos of Brassica napusaccumulate both triacylglycerols and proteins as major storage reserves. To evaluate metabolic fluxes during embryo development, we have established conditions for stable isotope labeling of cultured embryos under steady-state conditions. Sucrose supplied via the endosperm is considered to be the main carbon and energy source for seed metabolism. However, in addition to 220 to 270 mmcarbohydrates (sucrose, glucose, and fructose), analysis of endosperm liquid revealed up to 70 mm amino acids as well as 6 to 15 mm malic acid. Therefore, a labeling approach with multiple carbon sources is a precondition to quantitatively reflect fluxes of central carbon metabolism in developing embryos. Mid-cotyledon stageB. napus embryos were dissected from plants and cultured for 15 d on a complex liquid medium containing13C-labeled carbohydrates. The 13C enrichment of fatty acids and amino acids (after hydrolysis of the seed proteins) was determined by gas chromatography/mass spectrometry. Analysis of 13C isotope isomers of labeled fatty acids and plastid-derived amino acids indicated that direct glycolysis provides at least 90% of precursors of plastid acetyl-coenzyme A (CoA). Unlabeled amino acids, when added to the growth medium, did not reduce incorporation of 13C label into plastid-formed fatty acids, but substantially diluted 13C label in seed protein. Approximately 30% of carbon in seed protein was derived from exogenous amino acids and as a consequence, the use of amino acids as a carbon source may have significant influence on the total carbon and energy balance in seed metabolism. 13C label in the terminal acetate units of C20 and C22 fatty acids that derive from cytosolic acetyl-CoA was also significantly diluted by unlabeled amino acids. We conclude that cytosolic acetyl-CoA has a more complex biogenetic origin than plastidic acetyl-CoA. Malic acid in the growth medium did not dilute 13C label incorporation into fatty acids or proteins and can be ruled out as a source of carbon for the major storage components of B. napusembryos.
Aboriginal English: A Case for the Recognition of Prior Learning.

This paper discusses Aboriginal English speakers in Australia, noting the importance of recognizing prior learning and of recognizing Aboriginal English within the context of programs that understand the particular areas where Aboriginal English speakers need support to achieve outcomes in standard English. It defines recognition of prior learning (learning from experience that children bring to their schooling, particularly when the experience has been in a speech community different from that of the school), then discusses: prior learning and language/literacy acquisition, recognition of prior minority language knowledge and second language acquisition, Aboriginal English prior learning and education, and the relationship of dominant and alternative discourses. The paper goes on to discuss linguistic processes present in Aboriginal English, examining some of the phonological, morphological, syntactic, semantic, and discoursal processes, schemas, and genres that underlie it. Finally, it examines community (vernacular) literacy practices of aboriginal youth, presenting information from a study of the vernacular literacy practices, of Aboriginal high school students. Analyses were conducted at the sociolinguistic, linguistic, and semiotic levels. The paper concludes by presenting outcomes where Aboriginal English speakers' prior knowledge can be utilized and where speakers may need help in literacy education. (Contains 16 references.)

Analysis of the viewing zone of multiview autostereoscopic displays

The viewing zone of a multi-view autostereoscopic display can be shown to be completely determined by four parameters: the width of the screen, the optimal distance of the viewer from the screen, the width over which an image can be seen across the whole screen at this optimal distance (the eye box width), and the number of views. A multi-view display's viewing zone can thus be completely described without reference to the internal implementation of the device. These results can be used to determine what can be seen from any position in front of the display. This paper presents a summary of the equations derived in an earlier paper. These equations allow us to analyze an autostereoscopic display, as specified by the above parameters. We build on this work by using the derived equations to analyze the configurations of the extant models of the Cambridge autostereoscopic display: 10' 8- and 16-view, 25' 28-view, 50' 15-view displays and an experimental 25' 7-view display.
Prior Zero Forcing for Cognitive Relaying

Relaying primary signals by cognitive base-stations (CBSs) can help the primary system and thus win CBSs a higher chance to transmit their own signals. For this purpose, conventional zero-forcing (CZF) beamforming is a straightforward solution where the primary and cognitive signals are transmitted from a multi-antenna CBS without causing interference to each other. However, with CZF, no priority is given to the primary user (PU), which is not consistent with the idea of cognitive radio. In this paper, we shall propose a prior ZF (PZF) scheme which gives priority to the PU by transmitting primary signals without considering their interference to the cognitive users (CUs), while cognitive signals are not allowed to generate interference to the PU. As a result, PZF provides a better channel for the CBS-PU link than CZF but the same channel gain for the CBS-CU links as CZF. We compare PZF and CZF by considering both the transmit power with given target rates and the outage performance with given transmit power, where closed-form conditions are derived to indicate their respective advantages. One of the important contributions of this paper is to prove that, with one CU, a target rate of 1 bit/s/Hz for the CU is the key point that differentiates PZF and CZF, which is independent of the number of CBS-antennas, the channel distributions, and the signal-to-noise power ratio (SNR).
Aquaporin 9 Expression along the Male Reproductive Tract1

Abstract Fluid movement across epithelia lining portions of the male reproductive tract is important for modulating the luminal environment in which sperm mature and reside, and for increasing sperm concentration. Some regions of the male reproductive tract express aquaporin (AQP) 1 and/or AQP2, but these transmembrane water channels are not detectable in the epididymis. Therefore, we used a specific antibody to map the cellular distribution of another AQP, AQP9 (which is permeable to water and to some solutes), in the male reproductive tract. AQP9 is enriched on the apical (but not basolateral) membrane of nonciliated cells in the efferent duct and principal cells of the epididymis (rat and human) and vas deferens, where it could play a role in fluid reabsorption. Western blotting revealed a strong 30-kDa band in brush-border membrane vesicles isolated from the epididymis. AQP9 is also expressed in epithelial cells of the prostate and coagulating gland where fluid transport across the epithelium is important for secretory activity. However, it was undetectable in the seminal vesicle, suggesting that an alternative fluid transport pathway may be present in this tissue. Intracellular vesicles in epithelial cells along the reproductive tract were generally poorly stained for AQP9. Furthermore, the apical membrane distribution of AQP9 was unaffected by microtubule disruption. These data suggest that AQP9 is a constitutively inserted apical membrane protein and that its cell-surface expression is not acutely regulated by vesicular trafficking. AQP9 was detectable in the epididymis and vas deferens of 1-wk postnatal rats, but its expression was comparable with adult rats only after 3–4 wk. AQP9 could provide a route via which apical fluid and solute transport occurs in several regions of the male reproductive tract. The heterogenous and segment-specific expression of AQP9 and other aquaporins along the male reproductive tract shown in this and in our previous studies suggests that fluid reabsorption and secretion in these tissues could be locally modulated by physiological regulation of AQP expression and/or function.
The potential of televisions in the bedroom increasing a child's risk for obesity through decreased sleep times

OF THE THESIS The Potential of Televisions in the Bedroom Increasing a Child's Risk for Obesity Through Decreasing Sleep Times by Brittany Nicole Mellen Master of Public Health with a Concentration in Health Promotion and Behavioral Science San Diego State University, 2014 The purpose of this study was to determine if a television in a child’s bedroom is related to his/her risk for obesity through reduced sleep duration. Social Cognitive Theory provided the theoretical framework for this study. Data were collected through interviews with 104 caregivers who are participants in the intervention LUCES de Cambio. Caregivers were asked to report the typical bedtime and wake times of their child to determine average nightly sleep duration. The interview asked the caregivers to also report whether there was a television in the child’s bedroom. Baseline measurements were taken of the child’s height and weight to determine the child’s BMI percentile. Relationships were assessed with linear regression including bivariate and multivariate analyses. The children were Hispanic and had a mean age of 7.9 (SD=1.3). Fifty-seven percent of caregivers had a family monthly income of less than $2000 and 40% had less than a high school education. The average BMI percentile for children was 90.8 (SD=6.4). Twenty-one percent of the children had a healthy weight, 43% were overweight, and 39.5% were obese. There was a trend in the relationship between the presence of a television in the bedroom and a child’s BMI percentile. No significant relationship was found between sleep duration and a child’s BMI percentile. These findings suggest that it is important to investigate the impact of televisions in the bedroom on a child’s risk for obesity. Due to limitations in parent-reported sleep duration, future research should consider using objective measurements, such as an actigraph, to more precisely investigate the relationship between sleep and obesity risk in children.
Population structure of honey bees in the Carpathian Basin (Hungary) confirms introgression from surrounding subspecies

Abstract Carniolan honey bees (Apis mellifera carnica) are considered as an indigenous subspecies in Hungary adapted to most of the ecological and climatic conditions in this area. However, during the last decades Hungarian beekeepers have recognized morphological signs of the Italian honey bee (Apis mellifera ligustica). As the natural distribution of the honey bee subspecies can be affected by the importation of honey bee queens or by natural gene flow, we aimed at determining the genetic structure and characteristics of the local honey bee population using molecular markers. All together, 48 Hungarian and 84 foreign (Italian, Polish, Spanish, Liberian) pupae and/or workers were used for mitochondrial DNA analysis. Additionally, 53 sequences corresponding to 10 subspecies and the Buckfast hybrid were downloaded from GenBank. For the nuclear analysis, 236 Hungarian and 106 foreign honey bees were genotyped using nine microsatellites. Heterozygosity values, population‐specific alleles, FST values, principal coordinate analysis, assignment tests, structure analysis, and dendrograms were calculated. Haplotype and nucleotide diversity values showed moderate values. We found that one haplotype (H9) was dominant in Hungary. The presence of the black honey bee (Apis mellifera mellifera) was negligible, but a few individuals resembling other subspecies were identified. We proved that the Hungarian honey bee population is nearly homogeneous but also demonstrated introgression from the foreign subspecies. Both mitochondrial DNA and microsatellite analyses corroborated the observations of the beekeepers. Molecular analyses suggested that Carniolan honey bee in Hungary is slightly affected by Italian and black honey bee introgression. Genetic differences were detected between Polish and Hungarian Carniolan honey bee populations, suggesting the existence of at least two different gene pools within A. m. carnica.
Antithrombotic and thrombolytic therapy for ischemic stroke: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines.

OBJECTIVES This article provides recommendations on the use of antithrombotic therapy in patients with stroke or transient ischemic attack (TIA). METHODS We generated treatment recommendations (Grade 1) and suggestions (Grade 2) based on high (A), moderate (B), and low (C) quality evidence. RESULTS In patients with acute ischemic stroke, we recommend IV recombinant tissue plasminogen activator (r-tPA) if treatment can be initiated within 3 h (Grade 1A) or 4.5 h (Grade 2C) of symptom onset; we suggest intraarterial r-tPA in patients ineligible for IV tPA if treatment can be initiated within 6 h (Grade 2C); we suggest against the use of mechanical thrombectomy (Grade 2C) although carefully selected patients may choose this intervention; and we recommend early aspirin therapy at a dose of 160 to 325 mg (Grade 1A). In patients with acute stroke and restricted mobility, we suggest the use of prophylactic-dose heparin or intermittent pneumatic compression devices (Grade 2B) and suggest against the use of elastic compression stockings (Grade 2B). In patients with a history of noncardioembolic ischemic stroke or TIA, we recommend long-term treatment with aspirin (75-100 mg once daily), clopidogrel (75 mg once daily), aspirin/extended release dipyridamole (25 mg/200 mg bid), or cilostazol (100 mg bid) over no antiplatelet therapy (Grade 1A), oral anticoagulants (Grade 1B), the combination of clopidogrel plus aspirin (Grade 1B), or triflusal (Grade 2B). Of the recommended antiplatelet regimens, we suggest clopidogrel or aspirin/extended-release dipyridamole over aspirin (Grade 2B) or cilostazol (Grade 2C). In patients with a history of stroke or TIA and atrial fibrillation we recommend oral anticoagulation over no antithrombotic therapy, aspirin, and combination therapy with aspirin and clopidogrel (Grade 1B). CONCLUSIONS These recommendations can help clinicians make evidence-based treatment decisions with their patients who have had strokes.
Los insultos entre los jóvenes: la agresividad verbal como arma para la creación de una identidad grupal

Insults have been considered as an act of threatening, own speech deliberately of the impoliteness and the linguistic agressiveness . Nevertheless, the objective of our work will be to analyze, within the linguistic current of the pragmatic, to what extent these terms can be used in determined occasions -concretely in colloquial conversations between young people- right with the opposite objective: with the intention to cause a certain effect of politeness, because they are one of the resources that show the property to a group o generation. Insults between young people can be used to reinforce the feeling of group solidarity and the proximity between the interlocutors. For it, we will to analyze a transcription of a verbal interaction between young people publishec by Antonio Briz and the Val. Es. Co. group (2002)
A metaheuristic hybrid optimization technique for designing broadband FSS

This work presents a metaheuristic hybrid optimization technique developed to synthesize frequency selective surface (FSS) structures, composed of triangular patch elements and printed on FR-4 dielectric substrates for microwave filtering applications. The optimization technique is based on the combination of genetic algorithm (GA) and Multilayer Perceptron (MLP) artificial neural network (ANN). The developed MLP model for FSS synthesis was performed for efficient evaluation of cost function in GA iterations. The advantages in the optimal design of FSS through the proposed GA-ANN technique are discussed in terms of convergence and computational cost. An optimized FSS prototypes were fabricated and measured. The accuracy of the proposed optimization technique was verified through the good agreement obtained by means of comparison between theoretical and experimental results.
An Alternative Proof of an Extremal Entropy Inequality

This paper first focuses on deriving an alternative approach for proving an extremal entropy inequality (EEI), originally presented in [11]. The proposed approach does not rely on the channel enhancement technique, and has the advantage that it yields an explicit description of the optimal solution as opposed to the implicit approach of [11]. Compared with the proofs in [11], the proposed alternative proof is also simpler, more direct, more information-theoretic, and has the additional advantage that it offers a new perspective for establishing novel as well as known challenging results such the capacity of the vector Gaussian broadcast channel, the lower bound of the achievable rate for distributed source coding with a single quadratic distortion constraint, and the secrecy capacity of the Gaussian wire-tap channel. The second part of this paper is devoted to some novel applications of the proposed mathematical results. The proposed mathematical techniques are further exploited to obtain a more simplified proof of the EEI without using the entropy power inequality (EPI), to build the optimal solution for a special class of broadcasting channels with private messages and to obtain a mutual information-based performance bound for the mean square-error of a linear Bayesian estimator of a Gaussian source embedded in an additive noise channel.
Precise Bounded-Concurrent Zero-Knowledge in Almost Constant Rounds

Precise concurrent zero-knowledge is a new notion introduced by Pandey et al. in Eurocrypt'08, which captures the idea that the view of any verifier in concurrent interaction can be reconstructed in almost the same time. They also constructed some (private-coin) concurrent zero-knowledge argument systems for NP which achieve precision in different levels and all these protocols use at least ω (log n) rounds. In this paper we investigate the feasibility of reducing the round complexity and still keeping precision simultaneously. Our main result is that we construct a public-coin precise bounded-concurrent zero-knowledge argument system for NP only using almost constant rounds, i.e., ω (1) rounds. Bounded-concurrency means an a-priori bound on the (polynomial) number of concurrent sessions is specified before the protocol is constructed. Our result doesn't need any setup assumption.
Fast Parallel Molecular Solution to the Hitting-Set Problem

The hitting-set problem is an NP-complete problem in set theory. Assume that we have collection C of subsets of a finite set S, and a positive integer K les |S|, and we would like to know if there is a subset S' sube S with |S'| les K such that S' hits (contains) at least one element from each subset in C. In this paper, the DNA-based algorithm is proposed to solve the hitting-set problem. Furthermore, the simulated experiment is applied to verify correction of the proposed DNA-based algorithm for solving the hitting-set problem.
