Smart Vision

The vision of augmented reality is to provide users with relevant information to supplement their normal interactions with their environment. This technology promises to fundamentally improve many common applications that currently require specific devices or cumbersome interactions (e.g., driving directions, searches for local information, information about individuals with whom we interact, etc.). To achieve this vision, however, there are numerous technical challenges that still need to be addressed we are developing a system that can perform the key functionalities of an augmented-reality system: (1) sensing a user’s location and direction of view, (2) computing what to display in the user’s field of view, and (3) displaying the visual content without obstructing the user’s view of real objects. We present a design concept that aims to surpass prior attempts in its simplicity, efficiency, and functionality, to create a truly real-time fusion of analog and digital worlds. Our design consists of a sensor unit, an Intel Atom Processor, and a projector-based displa sensor unit obtains the live position and movement data of the users and sends it to the processor via a USB cable. The data is then processed through an integrated GPU and displayed by projecting onto a transparent surface
Relating schizotypy and personality to the phenomenology of creativity.

INTRODUCTION Although a considerable amount of research has addressed psychopathological and personality correlates of creativity, the relationship between these characteristics and the phenomenology of creativity has been neglected. Relating these characteristics to the phenomenology of creativity may assist in clarifying the precise nature of the relationship between psychopathology and creativity. The current article reports on an empirical study of the relationship between the phenomenology of the creative process and psychopathological and personality characteristics in a sample of artists. METHOD A total of 100 artists (43 males, 57 females, mean age = 34.69 years) from a range of disciplines completed the Experience of Creativity Questionnaire and measures of "positive" schizotypy, affective disturbance, mental boundaries, and normal personality. RESULTS The sample of artists was found to be elevated on "positive" schizotypy, unipolar affective disturbance, thin boundaries, and the personality dimensions of Openness to Experience and Neuroticism, compared with norm data. Schizotypy was found to be the strongest predictor of a range of creative experience scales (Distinct Experience, Anxiety, Absorption, Power/Pleasure), suggesting a strong overlap of schizotypal and creative experience. DISCUSSION These findings indicate that "positive" schizotypy is associated with central features of "flow"-type experience, including distinct shift in phenomenological experience, deep absorption, focus on present experience, and sense of pleasure. The neurologically based construct of latent inhibition may be a mechanism that facilitates entry into flow-type states for schizotypal individuals. This may occur by reduced latent inhibition providing a "fresh" awareness and therefore a greater absorption in present experience, thus leading to flow-type states.
Corneal asphericity in eye bank eyes implanted with the intrastromal corneal ring.

OBJECTIVE To evaluate the effects of the intrastromal corneal ring, a device developed to reduce myopia, on corneal asphericity in a large set of eye bank eyes. METHODS Forty-one deturgesced eye bank eyes were implanted with intrastromal corneal rings of five different thicknesses, ranging from 0.25 mm to 0.45 mm. Corneal asphericity, before and after implantation, was examined using two different metrologies. Corneal asphericity profiles were produced from dioptric power data collected from videokeratography. To statistically assess the corneal asphericity differences between exam times for each intrastromal corneal ring thickness, dependent sample confidence intervals (95%) were calculated for the mean differences between preoperative and postoperative measures for each topographic diameter zone. Laser holographic interferometry was used to inspect corneal asphericity in one eye bank eye case study for four intrastromal corneal ring sizes. Wave unit map and geometric zonal spot ray tracing analyses derived from laser holographic interferometry topography were surveyed. RESULTS Videokeratographic analysis suggested that preoperative corneal shape was prolate, i.e., flattened from central to paracentral cornea. Corneal shape became more prolate with intrastromal corneal ring implantation for all intrastromal corneal ring thicknesses. Laser holographic interferometry demonstrated that prolate asphericity was preserved with the intrastromal corneal ring sizes tested and that optical collection efficiency of the cornea was not diminished. CONCLUSION Using two different measurement techniques, this eye bank eye study demonstrated that intrastromal corneal rings maintain prolate corneal asphericity.
Robust PD Control Using Adaptive Compensation for Completely Restrained Parallel-Wire Driven Robots: Translational Systems Using the Minimum Number of Wires Under Zero-Gravity Condition

A parallel-wire driven mechanism uses flexible wires instead of heavy rigid links. In this paper, we propose a robust point-to-point (PTP) position control method in the task-oriented coordinates for completely restrained parallel wire-driven robots, which are translational systems using the minimum number of wires under zero-gravity conditions. In the cases where parallel-wire driven robots are disassembled/assembled and used outdoors (also applied in space), actuator positions would be uncertain or contain some errors. The error of internal force among wires that results from such uncertainty of actuator positions deteriorates positioning performance. To overcome such a difficulty, adaptive compensation is employed for robust PD control against the error of internal force, in this paper. It is necessary for the adaptive compensation to separate the internal force term linearly into a regressor matrix and a parameter vector concerned with the errors of actuator positions. The internal force term, however, possesses the nonlinear characteristic concerned with the errors of actuator position. Noting the structure of the internal force term, this paper shows that measuring both the position of an end-effector and wire length in real time enables the linear separation. Not only does this robust PD control method ensure precise positioning using external sensors; it enhances the robustness for uncertainty of the Jacobian matrix, which results from the error of actuator installation. First, we explain the linearization of the internal force term. Next, the robust PD control for the parallel-wire driven system using the uncertain Jacobian matrix is proposed; then, we prove the motion convergence to desired points and discuss its robustness based on Lyapunov stability analysis. Finally, the usefulness of the proposed control method is demonstrated through experiments and simulations.
Optimal Correlation Clustering via MaxSAT

We introduce an extensible framework for correlation clustering by harnessing the Maximum satisfiability (MaxSAT) Boolean optimization paradigm. The approach is based on formulating the correlation clustering task in an exact fashion as MaxSAT, and then using a state-of-the-art MaxSAT solver for finding clusterings by solving the MaxSAT formulation. Our approach allows for finding optimal clusterings wrt the objective function of the problem, extends to constrained correlation clustering-by allowing for easy integration of user-defined domain knowledge in terms of hard constraints over the clusterings of interest-as well as overlapping correlation clustering. First experiments on the scalability of the approach are presented.
A Radar Target Recognition Method Based on Circular Convolution Coefficients of High-Resolution Range Profiles

In order to extract robust features for radar high-resolution range profile (HRRP) recognition, a feature extraction method using circular convolution coe-fficients of HRRP is proposed in this paper. The features extracted by the proposed method represent the HRRP structure information which is more robust compared with local details. Moreover, this feature can make up for the loss of HRRP local details caused by feature selection. Due to the high dimensionality and nonlinear separability of HRRP features, feature selection based on kernel class separability was also used. Experiment results on simulation HRRP data sets are analyzed to demonstrate the efficiency of our method.
Combination of an ACE inhibitor and indapamide improves blood pressure control, but attenuates the beneficial effects of ACE inhibition on plasma adiponectin in patients with essential hypertension.

BACKGROUND Antihypertensive agents differentially influence the plasma adiponectin concentration and the effects of fixed-dose combination regimens remain unclear. The influence of a combination of an angiotensin-converting enzyme inhibitor (ACEI) and a thiazide-type diuretic or an ACEI alone on plasma adiponectin concentrations in patients with essential hypertension was evaluated in the present study. METHODS AND RESULTS After a 2-week placebo run-in phase, 30 patients with essential hypertension were randomized to receive preterax (2 mg perindopril/0.625 mg indapamide) or cilazapril (2.5 mg) once daily for 12 weeks. Plasma adiponectin and insulin concentrations were measured before and after treatment. Insulin resistance was measured by homeostasis assessment index (HOMA-IR). Treatment with preterax (P=0.003) and cilazapril (P=0.031) significantly reduced systolic blood pressure (BP), but only preterax reduced diastolic BP (P=0.024). Cilazapril treatment significantly increased the plasma adiponectin concentration (P=0.025) and reduced plasma triglycerides (P=0.041), whereas preterax treatment increased the plasma insulin concentration (P=0.041) and tended to increase HOMA-IR. CONCLUSIONS The combination of an ACEI and indapamide improved BP control, but attenuated the beneficial effects of ACE inhibition on plasma adiponectin in patients with essential hypertension. Such a combination may be best reserved for improved BP control rather than for metabolic protection in clinical hypertension.
Interfamily Conflict, Reproductive Success, and the Evolution of Male Homosexuality

In a preindustrial context, the mate choices of women are controlled by their parents, who require evidence of wealth and of ability to generate wealth from prospective sons-in-law in order to grant access to their daughters’ reproductive capacity. As a consequence, male siblings have to compete among themselves for controlling family resources required for successful reproduction. This competition increases interfamily conflict, decreasing each of the siblings’ inclusive fitness. Moreover, the sharing of resources among brothers reduces the chances that each one will be able to gain access to a high-quality female and/or to mate polygynously. It is proposed that male homosexuality has evolved to increase the reproductive success of male siblings and to decrease interfamily conflict. That is, by having a homosexual orientation, a younger male sibling increases his inclusive fitness by reducing competition over resources, whereas his older brothers enjoy higher reproductive success by having more resources available for reproduction. Finally, the reproductive costs of this sexual orientation are kept low by the elevated probability that a homosexual man will find himself in an arranged marriage where he is likely to have children.
EVALUATION OF STEREO ALGORITHMS FOR OBSTACLE DETECTION WITH FISHEYE LENSES

For autonomous navigation of micro aerial vehicles (MAVs), a robust detection of obstacles with onboard sensors is necessary in order to avoid collisions. Cameras have the potential to perceive the surroundings of MAVs for the reconstruction of their 3D structure. We equipped our MAV with two fisheye stereo camera pairs to achieve an omnidirectional field-of-view. Most stereo algorithms are designed for the standard pinhole camera model, though. Hence, the distortion effects of the fisheye lenses must be properly modeled and model parameters must be identified by suitable calibration procedures. In this work, we evaluate the use of real-time stereo algorithms for depth reconstruction from fisheye cameras together with different methods for calibration. In our experiments, we focus on obstacles occurring in urban environments that are hard to detect due to their low diameter or homogeneous texture.
Feature extractionand incremental learning to improve activity recognition on streaming data

In this paper, we propose an approach for an online human daily activity recognition system using motion sensor data. From the sensor readings, the system decides which activity is performed when the values change. It uses the previous measurements to interpret the current ones, without the need to wait for future information. The contributions of this study relies on the presentation of two methods to extract features from the sequence of sensor events, a clustering method to handle missing activity labels in dataset and an incremental learning method to deal with complexity and time spent in training since our system works on streaming data. Our methods are evaluated on publicly available real environment datasets.
Preferential Low Complexity Description Logics: Complexity Results and Proof Methods

In this paper we describe an approach for reasoning about typicality and defeasible properties in low complexity preferential Description Logics. We describe the non-monotonic extension of the low complexity DLs EL and DL-Litecore based on a typicality operator T, which enjoys a preferential semantics. We summarize complexity results for such extensions, called EL⊥Tmin and DL-LitecTmin. Entailment in DL-LitecTmin is in Π p 2 , whereas entailment in EL⊥Tmin is EXPTIME-hard. However, for the Left Local fragment of EL⊥Tmin the complexity of entailment drops to Π 2 . We present tableau calculi for Left Local EL⊥Tmin and for DL-LitecTmin. The calculi perform a two-phase computation in order to check whether a query is minimally entailed from the initial knowledge base. The calculi are sound, complete and terminating, and provide decision procedures for verifying entailment in the two logics, whose complexities match the above mentioned complexity results.
New insights on eye blindness and hand sight: Temporal constraints of visuo-motor networks

Pioneer experiments on saccadic suppression have shown that this effect is not followed by motor disorientation: Conscious perception of a target displacement can be dissociated from correct manual target reaching. It has subsequently been demonstrated that movement corrections with the same latency and spatial characteristics can be produced in conditions allowing perceptual awareness of perturbation of a target as in condition inducing saccadic suppression. In addition to the qualitative dissociation between motor performance and conscious awareness, quantitative temporal dissociations in action can be observed by manipulating different features of the visual target. When the target of an ongoing simple action is perturbed, a temporal advantage is found for responses to perturbations of location relative to colour and shape. Furthermore, there seems to be a temporal advantage for automatic motor corrections made in response to a target displacement as compared to other responses (other ongoing movement adjustments, movement interruption, conditional motor response such as pressing a key, verbal response, delayed matching-to-sample tasks). Thus, this paper reviews evidence for the fact that the temporal characteristics of any given response to a stimulus are dependent both on the sensory processes and on the type of response generated. Accordingly, identification responses (such as verbal report) to a visual stimulus are much slower than motor corrections of an ongoing movement in response to a target location change because of different processing times of the stimulus features (“What” compared to “Where”) and of the response itself (“What” compared to “How”). The existence of two continua (What/Where and What/How) is proposed between these two extreme stimulus- response combinations. This model may be a useful framework to better understand visuo-motor transformations and the network of connections between visual and motor areas.
Approaches Mediating Oxytocin Regulation of the Immune System

The hypothalamic neuroendocrine system is mainly composed of the neural structures regulating hormone secretion from the pituitary gland and has been considered as the higher regulatory center of the immune system. Recently, the hypothalamo-neurohypophysial system (HNS) emerged as an important component of neuroendocrine–immune network, wherein the oxytocin (OT)-secreting system (OSS) plays an essential role. The OSS, consisting of OT neurons in the supraoptic nucleus, paraventricular nucleus, their several accessory nuclei and associated structures, can integrate neural, endocrine, metabolic, and immune information and plays a pivotal role in the development and functions of the immune system. The OSS can promote the development of thymus and bone marrow, perform immune surveillance, strengthen immune defense, and maintain immune homeostasis. Correspondingly, OT can inhibit inflammation, exert antibiotic-like effect, promote wound healing and regeneration, and suppress stress-associated immune disorders. In this process, the OSS can release OT to act on immune system directly by activating OT receptors or through modulating activities of other hypothalamic–pituitary–immune axes and autonomic nervous system indirectly. However, our understandings of the role of the OSS in neuroendocrine regulation of immune system are largely incomplete, particularly its relationship with other hypothalamic–pituitary–immune axes and the vasopressin-secreting system that coexists with the OSS in the HNS. In addition, it remains unclear about the relationship between the OSS and peripherally produced OT in immune regulation, particularly intrathymic OT that is known to elicit central immunological self-tolerance of T-cells to hypophysial hormones. In this work, we provide a brief review of current knowledge of the features of OSS regulation of the immune system and of potential approaches that mediate OSS coordination of the activities of entire neuroendocrine–immune network.
Statistics of N-Body Simulations - Part Two - Equal Masses after Core Collapse

This paper presents and analyses statistical results from a large number of N -body simulations of isolated systems with equal masses, in which 250 ≤ N ≤ 2000. It concen-trates on the phase starting around the end of core collapse. Binaries play a crucial role, and we ﬁnd that the total energy of bound pairs is in line with theoretical expectations. Interpretation of the total number is complicated by the presence of a number of binaries on the hard/soft threshold. Interactions of hard binaries are consistent with the Spitzer (1987) cross section. The spatial evolution of the half-mass radius after core collapse nearly follows classical theory, and, by comparison with Fokker-Planck and gas models, allows a redetermination of the eﬀective thermal conductivity and the argument of the Coulomb logarithm in the expression for the relaxation time. The evolution of the inner parts of the system around the time of core bounce is consistent with these simpliﬁed models provided that the continuous production of energy, as usually assumed, is replaced by a model of stochastic energy production. Similarly, post-collapse evolution of the core requires a modest recalibration of the coeﬃcient of energy generation, especially for small N . These remarks refer to the behaviour averaged over many models; individual cases show alternate and irregular phases of expansion and recollapse. The distributions of velocity dispersion and anisotropy become remarkably homologous soon after core bounce. The bound mass of the systems very nearly follows a power law with time. A small number of escapers, presumed to be those associated with binary activity, dominate the energy which is carried oﬀ: the distribution of energies of escapers changes abruptly at the end of core collapse. The “internal” energy of escaping binaries is consistent with theoretical expectations, and again supports Spitzer’s reaction cross section for hard binaries.

Language Acquisition and Development : Proceedings of GALA 2009

INTRODUCTION The conference Generative Approaches to Language Acquisition is the biannual meeting of researchers who study language development from a generative point of view. Its importance for the development of research in the area, and as a forum for exchange of results and ideas is consensual. The edition of 2009 was organized by Centro de Linguística da Universidade Nova de Lisboa, and was held in Lisbon from September 9 till 11. The high selectivity of the conference can be seen by the fact that only about 30% of the submitted abstracts could be accepted for presentation. The conference included a general session, a workshop on Crosspopulation study of atypical language acquisition (organized by Laurie Tuller and Philippe Prévost, Université de Tours), a workshop on Sound structures and lexical representations (organized by Maria João Freitas and Paula Fikkert), and a poster session. The present volume contains 43 papers presented at GALA 2009. A quick look at the table of contents illustrates the diversity and richness of the conference and of this volume: the acquisition of languages from different families is studied; comparisons between acquisition of L1, L2 and atypical language development are made; all areas of language development are explored (phonology, morphology, syntax, semantics, lexicon, pragmatics and interactions between components). The proceedings of GALA are a very important and unavoidable reference in the literature on Language Acquisition, due to the quality of the work published therein. We are sure that this volume will be no exception to this. Introduction xii We are grateful to all contributors to the volume, and to the following institutions for the support given to the organization of GALA and to the preparation of this book:
A BIST Architecture For At-Speed DRAM Testing

A high-speed Built-In Self-Test (BIST) architecture for Dynamic Random Access Memories (DRAMs) is proposed. The circuit automatically generates a sequence of pre-defined test patterns for on-chip DRAM testing. The innovation herein is mainly an architecture consisting of two finite state machines, instead of the conventional single finite state machine. Based upon this architecture, the pipeline technique can then be applied to divide the pattern generation process into stages, leading to a higher-speed design which is capable of testing DRAM at speed for catching delay faults. In addition to pipelining, a technique referred to as protocolbased relaxation is also incorporated. This technique, imposing a certain protocol on the two communicating finite state machines, further relaxes the timing criticality of the design. Synthesis results show that the proposed BIST circuit can operate at the speed of as high as 400MHz using 0.35um CMOS technology.
