Whole Shape Measurement System Using a Single Camera and a Cylindrical Mirror

This paper proposes a three-dimensional measurement system with a simple structured system. The proposed system consists of a camera with a fish-eye lens and a cylinder whose inside is coated by a silver reflective layer. A target object is placed inside the cylinder and an image is captured by the camera from right above. The captured image includes sets of points that are observed from multiple viewpoints: one is observed directly, and the other is observed via the mirror. Therefore, the whole shape of the object can be measured using stereo vision in a single shot. An actual experimental situation was simulated and the accuracy is evaluated. In addition, a prototype system was implemented and the shape of the real object was measured
Design of a dual-band quadrifilar helix antenna

This paper presents a novel design of a dual-band Quadirfilar helix antenna. The helix antenna is formed by 4 printed strips, where 2 slots cut near the edge of each of the radiating arms are applied for dual-band property. Numerical simulation results show that this design can be used to produce dual frequency resonances, which can be used for applications in some satellite uplink and downlink frequency bands. In addition, the performance of this antenna remains pretty good even at higher frequencies.
Sequence Context of Indel Mutations and Their Effect on Protein Evolution in a Bacterial Endosymbiont

Indel mutations play key roles in genome and protein evolution, yet we lack a comprehensive understanding of how indels impact evolutionary processes. Genome-wide analyses enabled by next-generation sequencing can clarify the context and effect of indels, thereby integrating a more detailed consideration of indels with our knowledge of nucleotide substitutions. To this end, we sequenced Blochmannia chromaiodes, an obligate bacterial endosymbiont of carpenter ants, and compared it with the close relative, B. pennsylvanicus. The genetic distance between these species is small enough for accurate whole genome alignment but large enough to provide a meaningful spectrum of indel mutations. We found that indels are subjected to purifying selection in coding regions and even intergenic regions, which show a reduced rate of indel base pairs per kilobase compared with nonfunctional pseudogenes. Indels occur almost exclusively in repeat regions composed of homopolymers and multimeric simple sequence repeats, demonstrating the importance of sequence context for indel mutations. Despite purifying selection, some indels occur in protein-coding genes. Most are multiples of three, indicating selective pressure to maintain the reading frame. The deleterious effect of frameshift-inducing indels is minimized by either compensation from a nearby indel to restore reading frame or the indel’s location near the 3'-end of the gene. We observed amino acid divergence exceeding nucleotide divergence in regions affected by frameshift-inducing indels, suggesting that these indels may either drive adaptive protein evolution or initiate gene degradation. Our results shed light on how indel mutations impact processes of molecular evolution underlying endosymbiont genome evolution.

The Orthogonality Properties of Vector-Valued Two-dimensional Wavelet Packets with an Integer Dilation Factor

Wavelet analysis has been developing a popular mathematical branch for twenty years. In this paper the notion of orthogonal vector-valued two-dimensional wavelet packets, which is a generalization of uni-wavelet packets, is introduced. Their orthogonality properties are discussed by virtue of time-frequency analysis method, operator theory and matrix theory. Orthogonality formulas are established. Three orthonormal basis of L^2(R^2,C^{u}) is established from these orthogonal vector-valued wavelet packets.
Mammalian Mucosal α-Glucosidases Coordinate with α-Amylase in the Initial Starch Hydrolysis Stage to Have a Role in Starch Digestion beyond Glucogenesis

Starch digestion in the human body is typically viewed in a sequential manner beginning with α-amylase and followed by α-glucosidase to produce glucose. This report indicates that the two enzyme types can act synergistically to digest granular starch structure. The aim of this study was to investigate how the mucosal α-glucosidases act with α-amylase to digest granular starch. Two types of enzyme extracts, pancreatic and intestinal extracts, were applied. The pancreatic extract containing predominantly α-amylase, and intestinal extract containing a combination of α-amylase and mucosal α-glucosidase activities, were applied to three granular maize starches with different amylose contents in an in vitro system. Relative glucogenesis, released maltooligosaccharide amounts, and structural changes of degraded residues were examined. Pancreatic extract-treated starches showed a hydrolysis limit over the 12 h incubation period with residues having a higher gelatinization temperature than the native starch. α-Amylase combined with the mucosal α-glucosidases in the intestinal extract showed higher glucogenesis as expected, but also higher maltooligosaccharide amounts indicating an overall greater degree of granular starch breakdown. Starch residues after intestinal extract digestion showed more starch fragmentation, higher gelatinization temperature, higher crystallinity (without any change in polymorph), and an increase of intermediate-sized or small-sized fractions of starch molecules, but did not show preferential hydrolysis of either amylose or amylopectin. Direct digestion of granular starch by mammalian recombinant mucosal α-glucosidases was observed which shows that these enzymes may work either independently or together with α-amylase to digest starch. Thus, mucosal α-glucosidases can have a synergistic effect with α-amylase on granular starch digestion, consistent with a role in overall starch digestion beyond their primary glucogenesis function.
Quantum reactive scattering in three dimensions: Using tangent-sphere coordinates to smoothly transform from hyperspherical to Jacobi regions

Hyperspherical coordinates are well suited for treating rearrangement processes in the strong interaction region, and several different hyperspherical coordinates have been used successfully for quantum reactive scattering by various research groups. However, it is well known that asymptotically the appropriate set of coordinates (for a three particle system) are the three sets of Jacobi coordinates. In this paper we show how one can smoothly connect the hyperspherical coordinates in the rearrangement region to Jacobi coordinates in the nonrearrangement region using tangent-sphere coordinates. This procedure reduces the computational time required to solve the quantum Schrodinger equation and eliminates the need for numerical projection. To illustrate this method, we apply it to the F+H2⇌HF+F reaction, comparing reaction probabilities to those from previous benchmark calculations based on a conventional formulation.
Various image taking strategies for 3-D object modeling based on multiple cameras

A method is described for obtaining 3-D object models, particularly human models, based on multiple cameras and a computer. Existing optical 3-D modeling systems employ calibrated cameras, which inevitably restricts the cameras at fixed positions, giving constraints to object motions. The proposed technique gives various ways of capturing images of object motions. It contains a mobile cameras system for taking images of an object moving widely by following it. It also provides a simultaneous entire shape recovery strategy by the employment of a surrounding cameras system. The proposed recovery technique puts its theoretical basis on the factorization method. The present paper focuses its attention on the issue of defining a measurement matrix having full entries. The technique is described and its performance is shown by the experiments on 3-D human motion modeling.
Solving differential equations for 3-loop diagrams: relation to hyperbolic geometry and knot theory

In hep-th/9805025, a result for the symmetric 3-loop massive tetrahedron in 3 dimensions was found, using the lattice algorithm PSLQ. Here we give a more general formula, involving 3 distinct masses. A proof is devised, though it cannot be accounted as a derivation; rather it certifies that an Ansatz found by PSLQ satisfies a more easily derived pair of partial differential equations. The result is similar to Schlafli's formula for the volume of a bi-rectangular hyperbolic tetrahedron, revealing a novel connection between 3-loop diagrams and 1-loop boxes. We show that each reduces to a common basis: volumes of ideal tetrahedra, corresponding to 1-loop massless triangle diagrams. Ideal tetrahedra are also obtained when evaluating the volume complementary to a hyperbolic knot. In the case that the knot is positive, and hence implicated in field theory, ease of ideal reduction correlates with likely appearance in counterterms. Volumes of knots relevant to the number content of multi-loop diagrams are evaluated; as the loop number goes to infinity, we obtain the hyperbolic volume of a simple 1-loop box.
Antimony Glasses with Large Nonlinear Refractive Indices, Small Two-Photon Absorption Coefficients and Ultrafast Response at Telecom Wavelengths

Nonlinear (NL) optical properties of antimony oxide based glasses (AG) were characterized for excitation wavelengths from 800 to 1600 m. The NL refractive indices, n2, and the two-photon absorption (TPA) coefficient, beta , have been evaluated using the Z-scan technique. Values of n2 ap 10-15 - 10-14 cm2/W of electronic origin were measured and negligible TPA coefficients (beta< 0.003 cm/GW) were determined. The response time of the nonlinearity is faster than 100 fs as determined using the Kerr shutter technique. The figure - of-merit usually considered for all-optical switching, T = 2 betalambda/n2 , indicates that AG are very good materials for ultrafast switches at telecom wavelengths.
Multiple-block ahead branch predictors

A basic rule in computer architecture is that a processor cannot execute an application faster than it fetches its instructions. This paper presents a novel cost-effective mechanism called the two-block ahead branch predictor. Information from the current instruction block is not used for predicting the address of the next instruction block, but rather for predicting the block following the next instruction block.This approach overcomes the instruction fetch bottle-neck exhibited by wide-dispatch "brainiac" processors by enabling them to efficiently predict addresses of two instruction blocks in a single cycle. Furthermore, pipelining the branch prediction process can also be done by means of our predictor for "speed demon" processors to achieve higher clock rate or to improve the prediction accuracy by means of bigger prediction structures.Moreover, and unlike the previously-proposed multiple predictor schemes, multiple-block ahead branch predictors can use any of the branch prediction schemes to perform the very accurate predictions required to achieve high-performance on superscalar processors.
Haploidentical Stem Cell Transplantation in Adult Haematological Malignancies

Haematopoietic stem cell transplantation is a well-established treatment option for both hematological malignancies and nonmalignant conditions such as aplastic anemia and haemoglobinopathies. For those patients lacking a suitable matched sibling or matched unrelated donor, haploidentical donors are an alternative expedient donor pool. Historically, haploidentical transplantation led to high rates of graft rejection and GVHD. Strategies to circumvent these issues include T cell depletion and management of complications thereof or T replete transplants with GVHD prophylaxis. This review is an overview of these strategies and contemporaneous outcomes for hematological malignancies in adult haploidentical stem cell transplant recipients.
Asymmetric Information, Interviewer Behavior, and Unit Nonresponse

Unit nonresponse in surveys is generally taken to be the result of an unsuccessful interaction, or series of interactions, between an interviewer and a respondent. However, in the case of in-person surveys, the intensity of interactions, and even the pursuit of a situations that would allow interactions are largely under the control of interviewers. Survey managers normally know only a very limited part of the characteristics of sample members—often the managers only know whether or not a case is completed. In contrast, interviewers directly observe many characteristics of the sample. In the absence of effective monitoring, interviewers will tend to arrange their work on cases to suit their own preferences in light of their expectations based on the information they observe and whatever constraints and compensation arrangements are set by the managers. If interviewers’ preferences differ from those of the managers, they may apply effort to cases in a way that differs systematically from what would be desired by managers under an arrangement with more complete information unless this tendency is somehow offset through constraints or a compensation structure. The result of such a deviation would be a type of implicit field stratification—that is, participants may differ systematically from nonrespondents. This paper develops a very simple model of the information structure in a field survey, the nature of interviewer incentives, and the effects of differential field effort, and it provides illustrations based on the outcomes of the 1998 Survey of Consumer Finances. The paper argues for more attention to factors that determine the application of effort to individual cases in surveys. The views presented in this paper are those of the author alone, and they do not necessarily reflect the views of the Board of Governors of the Federal Reserve System or its staff. The author wishes to thank the central office staff—particularly Lisa Thalji and Mary Hess—the field managers and the interviewers at the National Opinion Research Center at the University of Chicago for collecting the data, and the respondents who gave their time for the interview.

Social Support and Career Optimism: Examining the Effectiveness of Network Groups Among Black Managers

As companies look for better ways to managediversity, one of the approaches that is emerging is theuse of female and minoritynetwork groups. These groupsare not well understood, and there has been no quantitative analysis of their impact onminority employees. Social network theory suggests thatnetwork groups should enhance the social resourcesavailable to women and minorities and in that wayenhance their chance of career success, but somecritics of network groups suggest that backlash mightproduce greater social isolation and discrimination. Inthis paper, we analyze a survey of members of theNational Black MBA Association to find out whethernetwork groups have a positive impact on careeroptimism, what specific effects of these groups are mostbeneficial, and whether groups enhance isolation ordiscrimination. Results indicate that network groups have apositive overall impact on career optimism of Blackmanagers, and that this occurs primarily via enhancedmentoring. Network groups have no effect ondiscrimination, either positive or negative. There are someindications of greater isolation, but also someindications of greater contact with Whites.
TabSol: An Efficient Framework to Defend Tabnabbing

Phishing attack is one of the most common cyber attacks causing serious threat to global cyber world and economy. Tab nabbing is a variant of phishing attack evolved recently, in which a malicious page opened in the tab disguises itself to the login page of a popular one, like gmail or facebook, so as to defeat the traditional phish detection mechanisms. In this paper, we propose an efficient security framework called Tab Sol to defend against Tab nabbing attack while detecting the other variants of phishing attacks. We developed and tested Tab Sol in the Google chrome browser and found to be effective. The proposed framework is compared with the existing frameworks and fund to more effective. The most attractive features of Tab Sol includes its simple and fast implementation with less false positive.
Agent based simulation of routine activity with social learning behavior

Routine activity theory and social learning theory are two most important aspects of criminal psychology. Routine activity theory states that criminal acts are caused due to the presence of criminals, victims and the absence of guardians in time and place. As the number of collision of these elements in place and time increases, criminal acts will also increase even if the number of criminals or civilians remains the same within the vicinity of a city. Street robbery is a typical example of routine activity theory and the occurrence of which can be predicted using routine activity theory. Agent-based models allow simulation of diversity among individuals. Therefore agent based simulation of street robbery can be used to visualize how chronological occurrences of human activity influence the incidence of street robbery. The conceptual model identifies three classes of people-criminals, civilians and police with certain activity areas for each. Police exist only as agents of formal guardianship. Criminals with a tendency for crime will be in the search for their victims. Civilians without criminal tendency can be either victims or guardians. These agents are subjected to random walk through a street environment guided by a Q-learning module and the possible outcomes are analyzed. Through the time period some civilian agents with a tendency to commit crime and have criminal background or criminal companions may turn into criminals. This phenomenon reflects social learning theory. The results compare gang and single robberies, robberies made on kids and women, tests on criminal social learning and comparison of different guardian patrolling strategies.
Distributed Graph Querying with Decoupled Storage and Smart Routing

During this project we developed an online distributed graph query processing system that is capable of handling queries on very large graphs that do not fit on the main memory of a commodity server. A common approach for tackling this problem is to split the graph up into several partitions and assign each of them to a server which then has the dual responsibility of storing part of the graph and processing queries. This design leads to problems like servers being overloaded by workloads that concentrate in one area of the graph and a large amount of inter-machine communication if many queries are at the border of graph partitions. To solve these problems, parts of the graph can be replicated and the partitions can be updated to adapt to the workload however this relies expensive operations like online workload monitoring and copying large amounts of data between machines. Our system avoids these problems by decoupling the graph storage and query processing. With this design, partitioning of the graph is not relevant since it is now encapsulated by the storage tier and queries no longer have specific servers they must be sent to, facilitating load balancing. However, query processing servers now need to retrieve graph data from storage servers which implies an extra communication cost. This cost is reduced by adding cache to the query processors that holds recently used graph data. In addition, smart routing schemes were developed to route queries to processors that are likely to have relevant data in their cache. We show that, not only our smart routing is able to significantly reduce communication overhead further but also that our system performs well, being able to outperform a state-of-the-art graph querying system. i
Metadata Independent Hashing for Media Identification &amp; P2P Transfer Optimisation

Efficient swarming behaviours within peer-to-peer networks are hindered by imprecise or incorrect metadata content. Once published, metadata corrections can only be effected by a complete republish/swarm recreation or for each peer to manually make corrections (causing them to leave the swarm, decreasing performance). This work presents an approach which enables a swarm to collaboratively upgrade embedded data to reflect changes in metadata, and to identify additional candidates which contain differing metadata but a correct payload. Swarm degradation due to peer drop-off resulting from edits is eliminated, and additional peers can be identified in a fully automated fashion, increasing swarm lifetime and performance. Arising from this metadata abstraction, automatic purification can be realised in situations where multiple incomplete/incorrect versions are available within one or more unconnected swarms. Variations associated with a content set are processed associatively using a knowledge discovery rule set to extrapolate a canonical tag set, which can also be reinforced using data from external corpora. After any update, these changes can again be automatically disseminated in a peer-to-peer swarm. The system presented enables context-aware P2P data transfers which abstract metadata optimally, while also maximising swarm size and enabling cataloguing of content. A proof-of-concept implementation is presented, and its impact on swarm purification/ optimisation is evaluated.
FAST PERCEPTUAL CONVOLUTION FOR ROOM REVERBERATION

The FIR-based reverberators, which convolve the input sequence with an impulse response modelling the concert hall, have better quality compared to the IIR-based approach. However, the high computational complexity of the FIR-based reverberators limits the applicability to most cost-oriented system. This paper introduces a method that uses perceptual criterion to reduce the complexity of convolution methods for reverberation. Also, an objective measurement criterion is introduced to check the perceptual difference from the reduction. The result has shown that the length of impulse response can be cut off by 60% without affecting the perceptual reverberation quality. The method is well integrated into the existing FFT-based approach is have around 30% speed-up.
