Toward a real-time tracking of dense point-sampled geometry

In this paper, we address the problem of tracking temporal deformations between two arbitrary densely sampled point-based surfaces. We propose an intuitive and efficient resolution to the point matching problem within two frames of a sequence. The proposed method utilizes two distinct space partition trees, one for each point cloud, which both are defined on a unique discrete space. Our method takes advantage of multi-resolution concerns, voxel adjacency relations, and a specific distance function. Experimental results obtained from both simulated and real reconstructed data sets demonstrate that the proposed method can handle efficiently the tracking process even for very large point clouds. Moreover, our method is easy to implement and very fast, which provides possibilities for real-time tracking applications.
Modal Adverbs in FDG: Putting the Theory to the Test

Abstract One of the distinctive features of the theory of Functional Discourse Grammar (FDG) is that it distinguishes various hierarchically organized layers of analysis, each of which is provided with a slot for modifiers relevant at the layer in question. Linear placement of these modifiers is determined by the layer to which they belong, with the ordering of elements taking place in a top-down, outward-inward manner. The model, in other words, makes predictions concerning the (relative) clausal position of different types of modifiers. In addition, the model places constraints on the occurrence of different types of modifiers in embedded environments (e.g. within the complement of certain types of verbs). Finally, the model places constraints on which modifiers can be expected to co-occur in coordinated constructions. The aim of the present paper is to test these predictions by examining the function, position and distribution of ten adverbs expressing various kinds of modality. Data from the British National Corpus (BYU-BNC) is used (i) to determine whether the predictions following from the overall organization of the FDG model are supported by empirical data; and (ii) to refine, where necessary, the classifications of modal adverbs proposed in the literature.
The weakest reasonable memory model

A memory model is some description of how memory behaves in a parallel computer s ystem. While there is consensus that sequential consistency [Lamport 1979] is the str onge t memory model, nobody seems to have tried to identify the weakest memory model. This thesis concerns itself with precisely this problem. We cannot hope to identify the weakest memory model unless we specify a minimal s et of properties we want it to obey. In this thesis, we identify five such propertie s: completeness, monotonicity, constructibility, nondeterminism confinement, and classica lity. Constructibility is especially interesting, because a nonconstructible model ca nnot be implemented exactly, and hence every implementation necessarily supports a str onger model. One nonconstructible model is, for example, dag consistency [Blumofe et al. 1996a]. We argue (with some caveats) that if one wants the five properties, then locat ion onsistency is the weakest reasonable memory model. In location consistency, every memory location is serialized, but different locations may be serialized independe ntly. (Location consistency is sometimes called coherence [Hennessy and Patterson 1996], and our location consistency isnot the model with the same name proposed by Gao and Sarkar [1994].) We obtain these results within a computation-centric theory of memory models, w here memory models are defined independently of scheduling issues and language semantics.
Catheter contact force estimation from shape detection using a real-time Cosserat rod model

This paper proposes a novel Cosserat rod model based method to estimate contact forces based on the shape analysis of the catheter. We simplify the original Cosserat rod model to achieve real-time estimation of the force magnitude and directions applied to the catheter tip. The simplified model contains a set of arithmetic equations, which can be rapidly solved using an iterative optimization algorithm. Experimental evaluation shows that the computational frequency of the force estimation was found to be 33.7Hz. Both the magnitude and the direction of the contact force were accurately estimated. The accuracy of the estimations of magnitude was 89.50%, and for the contact direction was 88.13%. Mean errors of the contact force and the contact angle are 7 × 10-4N and 0.931 degree respectively. To prove the concept, the catheter shape is detected through a RGB camera. However, the proposed method can be easily applied to existing catheter gating and detecting methods using the medical imaging environments such as X-ray fluoroscopy, CT, ultrasound, magnetic field and MRI. The results of evaluation experiments demonstrate what the proposed method is promising for force estimation without the need of a physical force sensor in various types of catheter tips.

04 03 07 4 v 1 7 M ar 2 00 4 Neutral top-pion and tγ ( z ) production at the HERA and THERA colliders

In the context of top-color assisted technicolor (TC2) models, we calculate the contributions of the neutral top-pion π t to tγ and tz production via the processes ep → γc → tγ and ep → γc → tz at the HERA and THERA colliders. Our results show that the cross sections σtγ(s) and σtz(s) are very small at the HERA collider with √ s = 320GeV . However, in most of the parameter space, σtγ(s) and σtz(s) are in the ranges of 0.14pb ∼ 1.37pb and 0.13pb ∼ 1.35pb at the THERA collider with √ s = 100GeV , respectively. ∗E-mail:cxyue@lnnu.edu. cn
Attributes affecting the level of tourist satisfaction with and loyalty towards theatrical performance in China: Evidence from a qualitative study

This study seeks to explore attributes affecting the level of tourist satisfaction with and loyalty towards theatrical performance in China. Based on four focus group discussions with 31 participants, the study identifies 34 attributes that affect the level of tourist satisfaction with theatrical performance, and groups them into five categories: stage, performance, venue, service, and tourist-related attributes. The findings on tourist loyalty reveal that most of the respondents would not watch the same theatrical performance alone in the future; however, they would recommend it to others. The study concludes with a discussion of the rich and insightful findings and their implications for tourism industry practitioners.
Evaluation of small organic acids present in fast pyrolysis bio‐oil from lignocellulose as feedstocks for bacterial bioconversion

Small organic acids derived from fast pyrolysis of lignocellulosic biomass represent a significant proportion of microbially accessible carbon in bio‐oil. However, using bio‐oil for microbial cultivation is a highly challenging task due to its strong adverse effects on microbial growth as well as its complex composition. In this study, the main small organic acids present in bio‐oil as acetate, formate and propionate were evaluated with respect to their suitability as feedstocks for bacterial growth. For this purpose, the growth behavior of four biotechnological production hosts—Escherichia coli, Pseudomonas putida, Bacillus subtilis, and Corynebacterium glutamicum—was quantified and compared. The bacteria were cultivated on single acids and mixtures of acids in different concentrations and evaluated using common biotechnological efficiency parameters. In addition, cultivation experiments on pretreated fast pyrolysis‐derived bio‐oil fractions were performed with respect to the suitability of the bacterial strains to tolerate inhibitory substances. Results suggest that both P. putida and C. glutamicum metabolize acetate—the major small organic acid generated during fast pyrolysis of lignocellulosic biomass—as sole carbon source over a wide concentration range, are able to grow on mixtures of small organic acids present in bio‐oil and can, to a limited extent, tolerate the highly toxic inhibitory substances within bio‐oil. This work provides an important step in search of suitable bacterial strains for bioconversion of lignocellulosic‐based feedstocks and thus contributes to establishing efficient bioprocesses within a future bioeconomy.

Changes in Tree Reproductive Traits Reduce Functional Diversity in a Fragmented Atlantic Forest Landscape

Functional diversity has been postulated to be critical for the maintenance of ecosystem functioning, but the way it can be disrupted by human-related disturbances remains poorly investigated. Here we test the hypothesis that habitat fragmentation changes the relative contribution of tree species within categories of reproductive traits (frequency of traits) and reduces the functional diversity of tree assemblages. The study was carried out in an old and severely fragmented landscape of the Brazilian Atlantic forest. We used published information and field observations to obtain the frequency of tree species and individuals within 50 categories of reproductive traits (distributed in four major classes: pollination systems, floral biology, sexual systems, and reproductive systems) in 10 fragments and 10 tracts of forest interior (control plots). As hypothesized, populations in fragments and control plots differed substantially in the representation of the four major classes of reproductive traits (more than 50% of the categories investigated). The most conspicuous differences were the lack of three pollination systems in fragments-pollination by birds, flies and non-flying mammals-and that fragments had a higher frequency of both species and individuals pollinated by generalist vectors. Hermaphroditic species predominate in both habitats, although their relative abundances were higher in fragments. On the contrary, self-incompatible species were underrepresented in fragments. Moreover, fragments showed lower functional diversity (H' scores) for pollination systems (−30.3%), floral types (−23.6%), and floral sizes (−20.8%) in comparison to control plots. In contrast to the overwhelming effect of fragmentation, patch and landscape metrics such as patch size and forest cover played a minor role on the frequency of traits. Our results suggest that habitat fragmentation promotes a marked shift in the relative abundance of tree reproductive traits and greatly reduces the functional diversity of tree assemblages in fragmented landscapes.
A Methane, Isolated, Planetary-Mass Object in Orion

We report on the discovery of a free-floating methane dwarf toward the direction of the young star cluster σ Ori. Based on the object's far-red, optical, and near-infrared photometry and spectroscopy, we conclude that it is a possible member of this association. We have named it S Ori J053810.1-023626 (S Ori 70 is the abridged name). If it is a true member of σ Ori, the comparison of the photometric and spectroscopic properties of S Ori 70 with state-of-the-art evolutionary models yields a mass of 3 Jupiter mass for ages between 1 and 8 Myr. The presence of such a low-mass object in our small search area (55.4 arcmin2) would indicate a rising substellar initial mass function in the σ Ori cluster, even for planetary masses.
Oxidative Stress and Lipid Peroxidation Products in Cancer Progression and Therapy

The generation of reactive oxygen species (ROS) and an altered redox status are common biochemical aspects in cancer cells. ROS can react with the polyunsaturated fatty acids of lipid membranes and induce lipid peroxidation. The end products of lipid peroxidation, 4-hydroxynonenal (HNE), have been considered to be a second messenger of oxidative stress. Beyond ROS involvement in carcinogenesis, increased ROS level can inhibit tumor cell growth. Indeed, in tumors in advanced stages, a further increase of oxidative stress, such as that occurs when using several anticancer drugs and radiation therapy, can overcome the antioxidant defenses of cancer cells and drive them to apoptosis. High concentrations of HNE can also induce apoptosis in cancer cells. However, some cells escape the apoptosis induced by chemical or radiation therapy through the adaptation to intrinsic oxidative stress which confers drug resistance. This paper is focused on recent advances in the studies of the relation between oxidative stress, lipid peroxidation products, and cancer progression with particular attention to the pro-oxidant anticancer agents and the drug-resistant mechanisms, which could be modulated to obtain a better response to cancer therapy.

A Wideband Receiver for Multi-Gbit/s Communications in 65 nm CMOS

High-rate communications technology leveraging the unlicensed spectrum around 60 GHz is almost ready for deployment with several demonstrations of successful wireless links. One key aspect of the transceiver is the ability to handle analog fractional bandwidths in the order of 20%, challenging for both the linear processing chain and the frequency reference generator. In classical LC loaded stages bandwidth trades with gain making them unsuitable for wide band amplifiers at millimeter-waves where the available device gain is relatively low. In this work, we exploit inter-stage coupling realizing higher order filters where wider bandwidth is achieved at the expense of in-band gain ripple only. The receiver adopts a sliding IF architecture employing an integer-N type-II synthesizer, with a three state phase frequency detector charge pump combination, a switched tuned LC VCO followed by a low power wide range divider chain. By judicious choice of charge pump current and filter components integrated phase noise, critical for signal constellation integrity at high rate, is kept low. This paper inspects the inter-stage coupling technique, providing design formulas, and discusses the design of each receiver block. Experiments performed on 65 nm prototypes provide: 6.5 dB maximum noise figure over >;13 GHz bandwidth, -22.5 dBc integrated phase noise while consuming 84 mW.
Cartesian impedance control of redundant robots: recent results with the DLR-light-weight-arms

This paper addresses the problem of impedance control for flexible joint robots based on a singular perturbation approach. Some aspects of the impedance controller, which turned out to be of high practical relevance during applications are then addressed, such as the implementation of nullspace stiffness for redundant manipulators, the avoiding of mass matrix decoupling and the related design of the desired damping matrix. Finally, the proposed methods are validated through measurements on the DLR robot.

Elimination of Complex RIAs without Automata

We present an algorithm that eliminates complex role inclusion axioms (RIAs) from a SROIQ ontology preserving all logical consequences not involving non-simple roles. Unlike other existing methods, our algorithm does not explicitly construct finite automata recognizing the languages generated by the RIAs. Instead, it is formulated as a recursive expansion of universal restrictions, similar to well-known encodings of transitivity axioms.
Immune-Complex Mimics as a Molecular Platform for Adjuvant-Free Vaccine Delivery

Protein-based vaccine development faces the difficult challenge of finding robust yet non-toxic adjuvants suitable for humans. Here, using a molecular engineering approach, we have developed a molecular platform for generating self-adjuvanting immunogens that do not depend on exogenous adjuvants for induction of immune responses. These are based on the concept of Immune Complex Mimics (ICM), structures that are formed between an oligomeric antigen and a monoclonal antibody (mAb) to that antigen. In this way, the roles of antigens and antibodies within the structure of immune complexes are reversed, so that a single monoclonal antibody, rather than polyclonal sera or expensive mAb cocktails can be used. We tested this approach in the context of Mycobacterium tuberculosis (MTB) infection by linking the highly immunogenic and potentially protective Ag85B with the oligomeric Acr (alpha crystallin, HspX) antigen. When combined with an anti-Acr monoclonal antibody, the fusion protein formed ICM which bound to C1q component of the complement system and were readily taken up by antigen-presenting cells in vitro. ICM induced a strong Th1/Th2 mixed type antibody response, which was comparable to cholera toxin adjuvanted antigen, but only moderate levels of T cell proliferation and IFN-γ secretion. Unfortunately, the systemic administration of ICM did not confer statistically significant protection against intranasal MTB challenge, although a small BCG-boosting effect was observed. We conclude that ICM are capable of inducing strong humoral responses to incorporated antigens and may be a suitable vaccination approach for pathogens other than MTB, where antibody-based immunity may play a more protective role.
A Comparision of College and High School Students in an Online IT Foundations Course

As computer science and information systems departments face declining enrollments, we must find ways to attract and retain students. One option is through partnering with high schools to attract students into the IT field. As we work to reach more students, distance learning offers an alternative method to reach many students. However, some argue that satisfaction levels of students taking distance learning courses is lower than that of students taking traditional courses. This study compares the satisfaction levels of high school students and college students taking an almost identical IT Foundations course. Preliminary results suggest that levels of satisfaction for the two groups are similarly high. Several potential areas of improvement in delivery of distance learning courses are also discussed.
Inside the black box of innovation : Strategic differences between SMEs

The downsizing waves in large enterprises have turned the attention towards the SME as an engine of economic growth and employment. Based on the early Schumpeterian ideas of ‘creative destruction’, it is often thought that innovative SMEs may be the solution. But who are these innovative SMEs? Do they really create employment? Are they performing better financially? This paper explores these questions in a population of Flemish SMEs active in the chemical and textile sector. First, a novel methodology is constructed to identify ‘innovative’ companies. Second, it is shown that innovative companies do not necessarily create more employment. In contrast, among them, we find also the ones that downsize most. Third, we argue that innovation is reflected in the long term, but not the short term financial performance of the company. Again, we find that the set of innovative SMEs is very heterogeneous. To further explore the strategic differences between innovative SMEs, we open the black box of innovation and come up with a set of 18 strategic competence factors. Based on these factors, a typology of innovative SMEs is suggested along the lines of current strategic thinking: the Porterian innovators, the resource based innovators and the Schumpeterian pioneers.
Failure-specific self-protecting multipaths — increased capacity savings or overengineering?

The self-protection multipath (SPM) is a simple protection switching mechanism. It distributes the traffic over several disjoint paths from source to destination according to a traffic distribution function. When a path fails, the traffic is redistributed to the working paths according to another traffic distribution function, i.e., the traffic distribution function depends on the failed path. The contribution of this work is the introduction of a failure-specific traffic distribution function for the SPM that depends on the exact failure of the paths. We present a linear program for the global optimization of the traffic distribution function of all SPMs in all protected failure scenarios. Finally, we compare the amount of protected traffic that can be transported in the network for the conventional SPM and the new failure-specific SPM (FSPM).
