Accurate, Scalable and Parallel Structure from Motion

In this paper, we tackle the accurate Structure from Motion (SfM) problem, in particular camera registration, far exceeding the memory of a single compute node. Different from the previous methods which drastically simplify the parameters of SfM, we preserve as many cameras, tracks and their corresponding connectivity as possible for a highly consistent and accurate SfM. By means of a camera clustering algorithm, we divide all the cameras and associated images into clusters and leverage such formulation to process the subsequent track generation, local incremental SfM and final bundle adjustment in a scalable and parallel scheme. Taking the advantages of both incremental and global SfM methods, we apply the relative motions from local incremental SfM to the global motion averaging framework and obtain more accurate and robust global camera poses than the state-of-the-art methods. We intensively demonstrate the superior performance of our method on the benchmark, Internet and our own challenging city-scale data-sets.
Language model transformation applied to lightly supervised training of acoustic model for congress meetings

For effective training of acoustic and language models for spontaneous speech such as meetings, it is significant to exploit the texts available in a large scale, which may not be faithful transcripts of the utterances. We have proposed a language model transformation scheme to cope with the differences between verbatim transcripts of spontaneous utterances and human-made transcripts such as those in proceedings. In this paper, we investigate its application to lightly supervised training of the acoustic model. By transforming the corresponding text in the proceedings, we can generate a very constrained model to predict the actual utterances. The experimental evaluation with the transcription system for the Japanese Congress meetings demonstrated that the proposed scheme can generate accurate labels for acoustic model training and thus realizes the comparable ASR (Automatic Speech Recognition) performance to the case using manual transcripts.
The Role of Motivated Reasoning in Optimistic Time Predictions

The authors explore the well-documented tendency for people to predict that they will finish tasks earlier than they actually do. Whereas previous research has tied this optimistic bias to the operation of specific cognitive processes, the present studies examine the interplay between motivation and cognition. Two studies supported the hypothesis that incentives to finish tasks quickly exacerbate the optimistic bias. An initial field study using a naturally occurring incentive manipulation demonstrated that individuals who expected an income tax refund were more (overly) optimistic in predicting when they would complete their income tax forms than those who did not expect a refund. A laboratory experiment using a word generation task replicated this general effect and identified mediating cognitive mechanisms: Monetary incentives for early completion led to optimistic predictions, increased attention to detailed future plans, and reduced attention to relevant past experiences.
Bayesian correction for covariate measurement error: A frequentist evaluation and comparison with regression calibration

Bayesian approaches for handling covariate measurement error are well established and yet arguably are still relatively little used by researchers. For some this is likely due to unfamiliarity or disagreement with the Bayesian inferential paradigm. For others a contributory factor is the inability of standard statistical packages to perform such Bayesian analyses. In this paper, we first give an overview of the Bayesian approach to handling covariate measurement error, and contrast it with regression calibration, arguably the most commonly adopted approach. We then argue why the Bayesian approach has a number of statistical advantages compared to regression calibration and demonstrate that implementing the Bayesian approach is usually quite feasible for the analyst. Next, we describe the closely related maximum likelihood and multiple imputation approaches and explain why we believe the Bayesian approach to generally be preferable. We then empirically compare the frequentist properties of regression calibration and the Bayesian approach through simulation studies. The flexibility of the Bayesian approach to handle both measurement error and missing data is then illustrated through an analysis of data from the Third National Health and Nutrition Examination Survey.
Both lipid environment and pH are critical for determining physiological solution structure of 3‐D‐conserved epitopes of the HIV‐1 gp41‐MPER peptide P1

In terms of background, the solution structure of monomeric peptide P1 (residues 649‐683), located in the conserved membrane proximal region (MPER) of HIV‐1 envelope glycoprotein gp41, is first reported here in dodecylphosphocholine (DPC) micelles. P1 is the minimal MPER region that permits interaction with the mucosal galactosyl ceramide HIV‐receptor; it also contains epitopes recognized by major gp41‐specific, broadly neutralizing immunoglobulin Gs (IgGs), 2F5 and 4E10, determinant in HIV fusion/infection. Our principal findings were as follows: the structural stability of P1 is pH dependent, as the α‐helix comprising Q653 I682, present at pH 3.3, is destabilized at higher pH values. At pH 6, the E‐rich N‐terminal half of P1 (residues 650666), partially overlapping the 2F5‐specific epitope, becomes fully disordered, while the W‐rich C‐terminal half conserves two shorter helices (W666‐W670 and W672‐ W680), separated by a well‐defined bend overlapped by the 4E10‐specific epitope. The two IgGs bind to P1 on DPC micelles with binding parameters (Kd) in the nanomolar range. Next, P1 was derivatized with phosphatidylethanolamine at its C terminal and inserted into liposomes of varied lipid composition, thereby enabling P1 to move laterally. Alternatively, an infectious virus‐binding assay was established. The Kd of both 2F5 and 4E10 IgGs measured on viral liposome and virus are similar and much lower than for the binding of the free peptide. In conclusion, P1, in a lipid environment, is an optimized MPER‐derived peptide suitable for designing an immunogen inducing broadly neutralizing antibodies to HIV. — Coutant, J., Yu, H. , Clément, M. ‐J., Alfsen, A. , Toma, F. , Curmi, P.

Recessive mutations in the kinase ZAK cause a congenital myopathy with fibre type disproportion

Congenital myopathies define a heterogeneous group of neuromuscular diseases with neonatal or childhood hypotonia and muscle weakness. The genetic cause is still unknown in many patients, precluding genetic counselling and better understanding of the physiopathology. To identify novel genetic causes of congenital myopathies, exome sequencing was performed in three consanguineous families. We identified two homozygous frameshift mutations and a homozygous nonsense mutation in the mitogen-activated protein triple kinase ZAK. In total, six affected patients carry these mutations. Reverse transcription polymerase chain reaction and transcriptome analyses suggested nonsense mRNA decay as a main impact of mutations. The patients demonstrated a generalized slowly progressive muscle weakness accompanied by decreased vital capacities. A combination of proximal contractures with distal joint hyperlaxity is a distinct feature in one family. The low endurance and compound muscle action potential amplitude were strongly ameliorated on treatment with anticholinesterase inhibitor in another patient. Common histopathological features encompassed fibre size variation, predominance of type 1 fibre and centralized nuclei. A peculiar subsarcolemmal accumulation of mitochondria pointing towards the centre of the fibre was a novel histological hallmark in one family. These findings will improve the molecular diagnosis of congenital myopathies and implicate the mitogen-activated protein kinase (MAPK) signalling as a novel pathway altered in these rare myopathies.
How Telephone Interviewers’ Responsiveness Impacts Their Success

Growing rates of nonresponse to telephone surveys can contribute to nonresponse error, and interviewers contribute differentially to nonresponse. Why do some telephone interviewers have better response rates than others? This study uncovered a critical behavior of successful telephone interviewers over the course of introductions: responsive feedback. Using detailed coding of telephone introductions, I explored interviewers’ speech. Interviewers were most responsive to answerers in contacts that resulted in deferrals and least responsive in refusals. Practical applications for telephone interviewer training are discussed.
EMC: The Effective Multi-Path Caching Scheme for Named Data Networking

The Named Data Networking (NDN) is proposed recently as a promising paradigm for the future Internet due to its built-in caching and name-based routing for efficient content distribution. For the time being, the research on NDN caching is still a preliminary topic, especially for the scenario of an ISP with multiple gateways. For more in-depth excavation, we have studied the effective intra-ISP caching under multiple gateways and multi-path routing in this paper. With the primary objective of reducing the inter-ISP traffic, we develop a popularity-based coordinated caching strategy named the Effective Multipath Caching scheme (EMC), which substantially saves more than 50% inter-ISP traffic and more than 30% content access latency. Through evaluation, we observe that EMC significantly outperforms the widely used Leaving Copies Everywhere (LCE) scheme and Leaving Copies with Probability (LCProb) scheme in terms of reducing both the inter-ISP traffic as well as the content access latency. Extensive simulation results demonstrate that our proposed caching scheme is effective, scalable and light-weight.

This paper proposes the sleep stage estimation method that can provide more accurate estimation than the conventional method and is robust to bad condition of humans without connecting any devices to human's body. Our proposed method can extract the specific wave pattern required to estimate the sleep stage from heart beat data. Through the intensive simulations by using the actual data of the human subjects, the following implications have been revealed: (1) the proposed method can provide more accurate sleep stage estimation than the conventional methods, and (2) he sleep stage estimation is robust to the bad physical conditions.
Joint base station selection and distributed compression for cloud radio access networks

This work studies joint base station (BS) selection and distributed compression for the uplink of a cloud radio access network. Multiple multi-antenna BSs are connected to a central unit, also referred to as cloud decoder, via capacity-constrained backhaul links. Since the signals received at different BSs are correlated, distributed source coding strategies for communication to the cloud decoder are potentially beneficial. Moreover, reducing the number of active BSs can improve the network energy efficiency, since BS energy consumption provides a major contribution to the overall energy expenditure for the network. An optimization problem is formulated in which compression and BS selection are performed jointly by introducing a sparsity-inducing term into the objective function. An iterative algorithm is proposed. From numerical results, it is observed that the proposed joint BS selection and compression algorithm performs close to the more complex exhaustive search solution.
ProtEST: protein multiple sequence alignments from expressed sequence tags

MOTIVATION An automatic sequence searching method (ProtEST) is described which constructs multiple protein sequence alignments from protein sequences and translated expressed sequence tags (ESTs). ProtEST is more effective than a simple TBLASTN search of the query against the EST database, as the sequences are automatically clustered, assembled, made non-redundant, checked for sequence errors, translated into protein and then aligned and displayed. RESULTS A ProtEST search found a non-redundant, translated, error- and length-corrected EST sequence for > 58% of sequences when single sequences from 1407 Pfam-A seed alignments were used as the probe. The average family size of the resulting alignments of translated EST sequences contained > 10 sequences. In a cross-validated test of protein secondary structure prediction, alignments from the new procedure led to an improvement of 3.4% average Q3 prediction accuracy over single sequences. AVAILABILITY The ProtEST method is available as an Internet World Wide Web service http://barton.ebi.ac.uk/servers/protest.html+ ++ The Wise2 package for protein and genomic comparisons and the ProtESTWise script can be found at http://www.sanger. ac.uk/Software/Wise2 CONTACT geoff@ebi.ac.uk
Cross-Cultural Validation of a Memorable Tourism Experience Scale (MTES)

The present study seeks to establish the cross-cultural validity of the memorable tourism experience scale (MTES), a recently developed measurement scale designed to assess individuals’ memorable tourism experiences (MTEs). Since the psychometric properties of the MTES have only been examined within a sample of American college students, the aim of this study was to replicate the previous psychometric findings using a sample of Taiwanese respondents. The data confirmed the validity of the previously established seven dimensions of MTES in the Taiwanese sample. Thus, the findings of the study suggest that MTES can generally be utilized to assess individuals’ MTEs in cross-cultural settings.
Educational intervention to sensitize future retirees and work colleagues about retirement from work

A two-phase comprehensive evaluation study for the purpose of evaluating lessons learned by and expectations of future retirees and their work colleagues by means of an educational sensitization strategy towards an understanding of retirement, by Aguilera et al., (2013). 20 employees (11 pre-retirees and nine colleagues) from a Mexican hospital participated in 2013. Date was gathered with the SQA-E form. The analysis implied an initial and final naturalist criterion evaluation. None, limited, clear and practical previous knowledge was found as well as personal, learning, political-economical and procedural interests. After the conference, theoretical, practical, and practical-theoretical knowledge was obtained and political-economical, economical-political, personal, preventive, contextual, physical health and no expectations were created. Understanding and empathy by work colleagues were achieved as well as the need to become prepared, plan and have political-economic awareness in all participants. Sensitizing the general public to understand retirement is recommended.
How, When, and Why Do Attribute-Complementary versus Attribute-Similar Cobrands Affect Brand Evaluations: A Concept Combination Perspective

Extant research on cobranding does not examine when and why complementarity or similarity between cobranding partners can be more effective. This research examines consumers’ reactions to cobranded partnerships that feature brands with either complementary or similar attribute levels, both of which are common in the marketplace. The results of six experiments show that consumers’ evaluations vary as a function of concept combination interpretation strategy (property mapping or relational linking) and whether cobranded partners have complementary or similar attributes. Specifically, when consumers use property mapping, they evaluate cobranded partnerships with complementary (vs. similar) attribute levels more favorably. In contrast, when using relational linking, they evaluate cobranded partnerships with complementary (vs. similar) attribute levels less favorably. The results also reveal that the breadth of the host brand (broad vs. narrow) and the type of advertising influence the extent to which consumers are likely to use property mapping or relational linking in evaluating cobranded partnerships.
Text Categorization from Category Name via Lexical Reference

Requiring only category names as user input is a highly attractive, yet hardly explored, setting for text categorization. Earlier bootstrapping results relied on similarity in LSA space, which captures rather coarse contextual similarity. We suggest improving this scheme by identifying concrete references to the category name's meaning, obtaining a special variant of lexical expansion.
Space-Time Block Coding (STBC) for Multiple Transmit Antennas over Time Selective Fading Channels

A study of space-time block coding in analytical formmultiple input and multiple output (STBC-MIMO) system was done in various cases. Initially, a basic Alamouti scheme for encoding was illustrated. Then, the performance of proposed STBC-MIMO was studied under varying a number of transmitting antennas, varying number of receiving antennas, varying channels, various modulations and also at varying rates. The simulation results were obtained for all cases. At each and every stage, a new encoding matrix was derived.
On Generalized SecondΦ -Variation of Normed Space Valued Maps

In this article we present a Young-type generalization of the concept of second variation for normed space valued functions defined on an interval (a, b) ⊂ . We show that a function f which take values on a Banach space X, is of bounded second Φ-variation, in the sense of Young, if and only if it can be expressed as the (Bochner) integral of a function of bounded (first) Φ-variation. This extend results of (11) and (13). Keywords and Phrases: Second Variation of a Function, Young Function. This paper is part of the first author's doctoral dissertation at the Universidad de los Andes, Merida, Venezuela. This research has been partly supported by the Central Bank of Venezuela. We want to give thanks to the library staff of B.C.V for compiling the references.
Cancer Therapy : Preclinical Tipping the Noxa / Mcl-1 Balance Overcomes ABT-737 Resistance in Chronic Lymphocytic Leukemia

Purpose: Chronic lymphocytic leukemia (CLL) cells in lymph nodes (LN), from which relapses are postulated to originate, display an antiapoptotic profile in contrast to CLL cells from peripheral blood (PB). The BH3 mimetic ABT-737 antagonizes the antiapoptotic proteins Bcl-XL and Bcl-2 but not Mcl-1 or Bfl-1. Previously, it was shown that CD40-stimulated CLL cells were resistant to ABT-737. We aimed to define which antiapoptotic proteins determine resistance to ABT-737 in CLL and whether combination of known antileukemia drugs and ABT-737 was able to induce apoptosis of CD40-stimulated CLL cells. Experimental Design: To mimic the LN microenvironment, PB lymphocytes of CLL patients were cultured on feeder cells expressing CD40L and treated with ABT-737 with or without various drugs. In addition, we carried out overexpression or knockdown of proand antiapoptotic proteins in immortalized
Retinoic Acids Potentiate BMP9-Induced Osteogenic Differentiation of Mesenchymal Progenitor Cells

Background As one of the least studied bone morphogenetic proteins (BMPs), BMP9 is one of the most osteogenic BMPs. Retinoic acid (RA) signaling is known to play an important role in development, differentiation and bone metabolism. In this study, we investigate the effect of RA signaling on BMP9-induced osteogenic differentiation of mesenchymal progenitor cells (MPCs). Methodology/Principal Findings Both primary MPCs and MPC line are used for BMP9 and RA stimulation. Recombinant adenoviruses are used to deliver BMP9, RARα and RXRα into MPCs. The in vitro osteogenic differentiation is monitored by determining the early and late osteogenic markers and matrix mineralization. Mouse perinatal limb explants and in vivo MPC implantation experiments are carried out to assess bone formation. We find that both 9CRA and ATRA effectively induce early osteogenic marker, such as alkaline phosphatase (ALP), and late osteogenic markers, such as osteopontin (OPN) and osteocalcin (OC). BMP9-induced osteogenic differentiation and mineralization is synergistically enhanced by 9CRA and ATRA in vitro. 9CRA and ATRA are shown to induce BMP9 expression and activate BMPR Smad-mediated transcription activity. Using mouse perinatal limb explants, we find that BMP9 and RAs act together to promote the expansion of hypertrophic chondrocyte zone at growth plate. Progenitor cell implantation studies reveal that co-expression of BMP9 and RXRα or RARα significantly increases trabecular bone and osteoid matrix formation. Conclusion/Significance Our results strongly suggest that retinoid signaling may synergize with BMP9 activity in promoting osteogenic differentiation of MPCs. This knowledge should expand our understanding about how BMP9 cross-talks with other signaling pathways. Furthermore, a combination of BMP9 and retinoic acid (or its agonists) may be explored as effective bone regeneration therapeutics to treat large segmental bony defects, non-union fracture, and/or osteoporotic fracture.
