Design of Single-Branch Laminated Waveguide Diplexers Using Modal Orthogonality

This paper develops novel laminated waveguide diplexers by taking advantage of the modal orthogonality of multiple cavity modes. The uplink and downlink channels of the diplexer can share a common filter structure, which minimizes the number of the cavities. The feeding probes and coupling slots are adequately located to achieve the required coupling coefficients and external quality factors at both passbands simultaneously. In this way, the matching network, i.e., T-junction, adopted in the traditional diplexer design can be eliminated. In addition, by the symmetric but orthogonal field distributions of two operation modes, nearly 30 dB of isolation can be achieved even by sharing the common cavities. The cavities are vertically stacked in low-temperature cofired ceramic technology, which further miniaturizes the circuit size. Two diplexers with third-order Chebyshev responses are designed and fabricated with different operation modes to show the flexibility in the band allocation. Experimental and simulated results are presented, both validating the design concept of the proposed diplexers.
A classification of author co-citations: Definitions and search strategies

The term author co-citation is defined and classified according to four distinct forms: the pure first-author co-citation, the pure author co-citation, the general author co-citation, and the special co-author/co-citation. Each form can be used to obtain one count in an author co-citation study, based on a binary counting rule, which either recognizes the co-citedness of two authors in a given reference list (1) or does not (0). Most studies using author co-citations have relied solely on first-author cocitation counts as evidence of an author's oeuvre or body of work contributed to a research field. In this article, we argue that an author's contribution to a selected field of study should not be limited, but should be based on his/her complete list of publications, regardless of author ranking. We discuss the implications associated with using each co-citation form and show where simple first-author co-citations fit within our classification scheme. Examples are given to substantiate each author co-citation form defined in our classification, including a set of sample DialogTM searches using references extracted from the SciSearch database.
Virtual Institutions for Preserving and Simulating the Culture of Mount Bego's Ancient People

The Alps of southeastern France, better known as the Valley of Marvels, hide an impressive collection of engravings, mostly visible on the rocks around Mount Bego, which are irreplaceable witnesses of what life of the people who created them looked like. This calls for immediate action on promoting the awareness of this cultural treasure, which is hardly accessible by interested common men, as well as on helping domain experts to analyze these engravings and share their understanding and theories about them with other experts and the public. In this position paper, we propose a set of technologies (some of which are partially implemented) for digital preservation of available data about the region. Our technology will allow domain experts to: (i) organize and structure data into an existing collaborative tool set, (2) process it, (3) make assumptions about the way of life of the ancient people based on the data, (4) make the results of such activities available in form of 3D Virtual Worlds.
The feedback capacity of the binary symmetric channel with a no-consecutive-ones input constraint

The binary symmetric channel (BSC) with feedback is considered, where the input sequence contains no consecutive ones, i.e., satisfies the (1,∞)-RLL constraint. In [1], the capacity of this setting was formulated as dynamic programming (DP); however, analytic expressions for capacity and optimal input distribution were left as an open problem. In this paper, we derive explicit expressions for both feedback capacity and optimal input distribution. The solution was obtained by using an equivalent DP and solving its corresponding Bellman equation. The feedback capacity also serves as an upper bound on the capacity of the input-constrained BSC channel without feedback, a problem that is still open.
Adding OWL-S to UDDI, implementation and throughput

The increasing availability of web services demands for a discovery mechanism to find services that satisfy our requirement. UDDI provides a web wide registry of web services, but its lack of an explicit capability representation and its syntax based search provided produces results that are coarse in nature. We propose to base the discovery mechanism on OWL-S. OWL-S allows us to semantically describe web services in terms of capabilities offered and to perform logic inference to match the capabilities requested with the capabilities offered. We propose OWL-S/UDDI matchmaker that combines the better of two technologies. We also implemented and analyzed its performance.
Incremental abstraction planning for limited-time situations

A planning agent needs the ability to plan some of its responses at run time. Because of the limited time available at run time, the agent must build its plans incrementally so that partial results may be used when time is too short to build a complete plan. We have developed an approach to incremental planning that adapts to a changing environment, while at the same time taking advantage of a temporal representation and multiple levels of abstraction. The planner incrementally builds plans forward at multiple levels of abstraction to produce usable partial results. In addition, the approach models the dynamic and continuous nature of the real world by representing the world and plans temporally. The method also handles changes in the world by continually updating its world model and adapting its plan as an integral part of the planning process.
The role of image composition in image aesthetics

In this paper, we explore the role that image composition plays in image aesthetic appeal classification. We propose low-level image composition features that approximate traditional photography composition guidelines, such as simplicity and visual balance (e.g. golden mean, golden triangles). We then use these features to build an image aesthetics classifier that we test with a baseline dataset. Interestingly, our approach, that only takes into account image composition features, yields close to state-of-the-art image aesthetic-based classification accuracies, which highlights the importance of image composition in image aesthetic appeal assessment.
Emotional Advisor to help children with autism in social communication

The deficit or impairment in the ability to rationalize emotional states is known as mind-blindness. This condition is seen to be the key inhibitor of social and emotional intelligence for autistic people. Autism is a spectrum of neuro-developmental conditions which affects one's social functioning, communication and is often accompanied with repetitive behaviours and obsessive interests. Inabilities resulting from mind-blindness include gauging the interest of other parties during conversations, withdrawal from social contact, oblivion to social cues, in difference to people's opinions and incomprehensible non-verbal communication. The existing assistive devices and tools mostly serve as remedial tools that provide a learning environment for autistic children to learn about the norms of social behaviour. However, these tools lack the capability to operate in conjunction with real-world situations. An idea is proposed that aims to fulfill this need. We propose a portable device which is able to assist autistic people in communication in real-life situations. We believe that this portable device can help to narrow the gap between us and the world of autism through assisted communication. In this paper, we present one part of this device which is called Emotional Advisor to assist autistic children in engaging in meaningful conversations where people are able to ascertain how they are feeling during communication.
The Experimental College

A classic in the history of American higher education The Experimental College is the record of a radical experiment in university education. Established at the University of Wisconsin in Madison in 1927 by innovative educational theorist Alexander Meiklejohn, the "Experimental College" itself was to be a small, residence-based program within the larger university that provided a core curriculum of liberal education for the first two years of college. Aimed at finding a method of teaching whereby students would gain "intelligence in the conduct of their own lives," the Experimental College gave students unprecedented freedom. Discarding major requirements, exams, lectures, and mandatory attendance, the program reshaped the student-professor relationship, abolished conventional subject divisions, and attempted to broadly connect the democratic ideals and thinking of classical Athens with the dilemmas of daily life in modern industrial America. Meiklejohn's program closed its doors after only five years, but this book, his final report on the experiment, examines both its failures and its triumphs. This edition brings back into print Meiklejohn's original, unabridged text.
Energetics of Copper Trafficking between the Atx1 Metallochaperone and the Intracellular Copper Transporter, Ccc2*

The Atx1 metallochaperone protein is a cytoplasmic Cu(I) receptor that functions in intracellular copper trafficking pathways in plants, microbes, and humans. A key physiological partner of the Saccharomyces cerevisiae Atx1 is Ccc2, a cation transporting P-type ATPase located in secretory vesicles. Here, we show that Atx1 donates its metal ion cargo to the first N-terminal Atx1-like domain of Ccc2 in a direct and reversible manner. The thermodynamic gradient for metal transfer is shallow (K exchange = 1.4 ± 0.2), establishing that vectorial delivery of copper by Atx1 is not based on a higher copper affinity of the target domain. Instead, Atx1 allows rapid metal transfer to its partner. This equilibrium is unaffected by a 50-fold excess of the Cu(I) competitor, glutathione, indicating that Atx1 also protects Cu(I) from nonspecific reactions. Mechanistically, we propose that a low activation barrier for transfer between partners results from complementary electrostatic forces that ultimately orient the metal-binding loops of Atx1 and Ccc2 for formation of copper-bridged intermediates. These thermodynamic and kinetic considerations suggest that copper trafficking proteins overcome the extraordinary copper chelation capacity of the eukaryotic cytoplasm by catalyzing the rate of copper transfer between physiological partners. In this sense, metallochaperones work like enzymes, carefully tailoring energetic barriers along specific reaction pathways but not others.
Orthogonal tensor invariants and the analysis of diffusion tensor magnetic resonance images

This paper outlines the mathematical development and application of two analytically orthogonal tensor invariants sets. Diffusion tensors can be mathematically decomposed into shape and orientation information, determined by the eigenvalues and eigenvectors, respectively. The developments herein orthogonally decompose the tensor shape using a set of three orthogonal invariants that characterize the magnitude of isotropy, the magnitude of anisotropy, and the mode of anisotropy. The mode of anisotropy is useful for resolving whether a region of anisotropy is linear anisotropic, orthotropic, or planar anisotropic. Both tensor trace and fractional anisotropy are members of an orthogonal invariant set, but they do not belong to the same set. It is proven that tensor trace and fractional anisotropy are not mutually orthogonal measures of the diffusive process. The results are applied to the analysis and visualization of diffusion tensor magnetic resonance images of the brain in a healthy volunteer. The theoretical developments provide a method for generating scalar maps of the diffusion tensor data, including novel fractional anisotropy maps that are color encoded for the mode of anisotropy and directionally encoded colormaps of only linearly anisotropic structures, rather than of high fractional anisotropy structures.

Modeling and Validation of Silicon Contour-Based Extraction and Simulation of Non-Uniform Devices

A current density-based model that incorporates narrow width effects is proposed to predict the drawn current of transistors that exhibit non-uniform device geometry. A continuous, integrable, analytical model of current density that includes the details of stress, edge effects and dopant loss/pileup is first calibrated to silicon data or existing SPICE models. Using the active and poly contours of the actual transistor shape obtained from a lithography-like simulation with an enriched model or directly from SEM images, the current density model is integrated over the width of the transistor to obtain its drawn current. From this predicted current, equivalent transistor parameters for circuit simulation can be extracted. Comparison to silicon drive current measurements of poly T and active T structures on a ST 65 nm process show excellent correlation, with an average difference of less than 0.5% for active shapes and 0.8% for poly shapes.
Thoughts and emotion assimilation and detonation through VR for people with ASD

This study proposes a new tool based on Virtual Reality (VR) as a complement in the treatment of people diagnosed with Autism Spectrum Disorder (ASD). VR tools have been stablished in last years as a new option in learning and practising new skills during the treatment. In this work, a VR application is developed simulating several environments corresponding to diﬀerent types of emotions according to the Gestalt school of psychology. The VR application was tested in five male teenagers diagnosed with ASD of level one according to the DSM-5 during the therapy sessions. A qualitative evaluation of the VR application is carried out by the therapist during the session. It is observed and annotated which emotions have been detonated by the VR application giving to the therapist new information for the subsequent sessions.
SysObjC: C extension for development of object-oriented operating systems

Object-oriented operating systems prefer to consider every data structure as an object. However, data structures predefined by the hardware's manufacturer do not fit into this scheme. First of all, traditional object-oriented languages do not support objects with user-defined representation, which would be needed to these data structures as objects. Secondly, classic object-oriented languages have an overhead unacceptable for operating systems. To overcome both problems we introduce predicate classes into C as an extension of the standard structures. Inheritance is based on overlapping reserved fields without extending the object in size, which enables polymorphism by value, a very important feature in system programming. Dispatcher routines of methods add no significant overhead compared to standard C.
Progressive Loss of Cd8 + T Cell-mediated Control of a ~/-herpesvirus in the Absence of Cd4 + T Cells

A unique experimental model has been developed for dissecting the integrity of CD8 + T cellmediated immunity to a persistent gammaherpesvirus under conditions of CD4 + T cell deficiency. Respiratory challenge of major histocompatibility complex class II / and + / + C57BL/6J mice with the murine gammaherpesvirus 68 (MHV-68) leads to productive infection of both lung and adrenal epithelial cells. Virus titers peak within 5-10 d, and are no longer detected after day 15. Persistent, latent infection is established concurrently in splenic and lymph node B cells, with higher numbers of MHV-68 § lymphocytes being found in all lymphoid sites analyzed from the + / + mice concurrent with the massive, but transient splenomegaly that occurred only in this group. From day 17, however, the numbers of infected B lymphocytes were consistently higher in the / group, while the frequency of this population diminished progressively in the + / + controls. Infectious MHV-68 was again detected in the respiratory tract and the adrenals of the / (but not the + / + ) mice from day 22 after infection. The titers in these sites rose progressively, with the majority of the / mice dying between days 120 and 133. Even so, some CD8 + effectors were still functioning as late as 100 d after infection. Depletion of CD8 + T cells at this stage led to higher virus titers in the / lung, and to the development of wasting in some of the / mice. Elimination of the CD8 + T cells from the + / + group (day 80) increased the numbers o fMHV-68 + cells in the spleen, but did not reactivate the infection in the respiratory tract. The results are consistent with the interpretation that CD8 + T cell-mediated control of this persistent gammaherpesvirus is progressively lost in the absence of the CD4 + T cell subset. This parallels what may be happening in AIDS patients who develop Kaposi's sarcoma and various Epstein Barr virus-associated disease processes.
PRoPHET Routing Protocol Based on Neighbor Node Distance Using a Community Mobility Model in Delay Tolerant Networks

In a Delay Tolerant Network (DTN), the Probabilistic Routing Protocol using the History of Encounters and Transitivity (PRoPHET) routing protocol mainly uses the delivery predictability of node encounters and transitivity to select and forward bundles to the desired neighbor nodes regardless of their distance. This concept introduces a delivery dilemma and the drawbacks of a low delivery ratio, high delay, and overhead when two or more neighbor nodes carry equal delivery predictability when the distance from these nodes to the source node varies from high node mobility. To solve these problems, we propose the use of the Distance-based PRoPHET (DiPRoPHET), a modified version of the traditional PRoPHET, along with the use of a DTN cross-layer implementation for distance value retrieval. We also conducted a simulation between the proposed protocol and a traditional protocol using both random and community models. The simulation results show that, by adding a distance metric to the existing PRoPHET delivery predictability vector, the bundle delivery ratio is increased, in contrast, the bundle delay and overhead are decreased during delivery dilemmas regarding the node to be selected as a message forwarder.
Achievements, Open Problems and Challenges for Search Based Software Testing

Search Based Software Testing (SBST) formulates testing as an optimisation problem, which can be attacked using computational search techniques from the field of Search Based Software Engineering (SBSE). We present an analysis of the SBST research agenda, focusing on the open problems and challenges of testing non-functional properties, in particular a topic we call 'Search Based Energy Testing' (SBET), Multi-objective SBST and SBST for Test Strategy Identification. We conclude with a vision of FIFIVERIFY tools, which would automatically find faults, fix them and verify the fixes. We explain why we think such FIFIVERIFY tools constitute an exciting challenge for the SBSE community that already could be within its reach.
Relationship between classroom social goal structures, gender, and social outcomes in Japanese elementary school children

This study examines the interaction between gender and classroom social goal structures and the impact they have on children's prosocial behaviors and classroom adjustment. Specifically, classroom social goal structures (consisting of prosocial and compliance goal structure) are the degree to which focal social goals are presented in classrooms. Numerous previous studies have tested the gender differences in social outcomes; however, the results of such past studies have been mixed, as some detected gender differences while others did not. This suggests the existence of moderator variables. Consequently, in this research, we focused on classroom-level moderators in the relationship between gender and social outcomes. We analysed a sample of 3,609 Japanese public elementary school children from 114 classrooms, and we detected the presence of cross-level interactions and found that classroom social goal structures can promote or degrade boys' social outcomes.
The Impact of Fluctuating Financial Markets on the Signaling Effect of E-Commerce Announcements

This paper presents an event study of business signaling through electronic commerce announcements during fluctuating financial markets. This topic is of unique and substantial importance. If there are abnormal returns on an eCommerce initiative, and these returns are different during bull and bear markets, then we know that the markets value these investments, but the value is subjective rather than inherent to the investment. If the value is subjective, then gains to the investor and corporation itself will vary in sympathy with market movement. This paper researches these new aspects of returns due to eCommerce announcements and compares them with other recent studies. We use event study methodology and assess the cumulative abnormal returns from eCommerce initiatives announced by firms in the S&P 100 Index between January 1999 and December 2000.
Processing of Semipolar and Nonpolar InGaN Based Laser Diodes

Laser diodes (LDs) based on InGaN quantum well (QW) structures emitting in the blue to green spectral region are of great interest for applications ranging from spectroscopy to laser projectors for mobile devices. Whereas LDs in the blue spectral region are available commercially, the so-called “green gap” is just at the point of being bridged. The necessity of creating InGaN QWs with high indium content in order to achieve longer wavelengths leads to an aggravation of epitaxial challenges. Optimal growth conditions for the active region become increasingly different from the surrounding GaN layers with increasing In content. Furthermore, the lattice mismatch between GaN and InGaN induces strong polarization fields along the commonly used polar directions, thus resulting in a reduced recombination rate, due to the quantum confined Stark effect (QCSE). The QCSE draws the wave functions of electrons and holes apart, thereby decrasing the wave function overlap. This inherent issue can be avoided or alleviated by the growth of the active region on nonpolar or semipolar planes [1].
