Multi-Sensory synergies in Humanoid Robotics

Sensing is a key element for any intelligent robotic system. This paper describes the current progress of a project in the Intelligent Robotics Research Center at Monash University that has the aim of developing a synergistic set of sensory systems for a humanoid robot. Currently, sensing modes for colour vision, stereo vision, active range, smell and airflow are being developed in a size and form that is compatible with the humanoid appearance. Essential considerations are sensor calibration and the processing of sensor data to give reliable information about properties of the robot's environment. In order to demonstrate the synergistic use of all of the available sensory modes, a high level supervisory control scheme is being developed for the robot. All time-stamped sensor data together with derived information about the robot's environment are organized in a blackboard system. Control action sequences are then derived from the blackboard data based on a task description. The paper presents details of each of the robot's sensory systems, sensor calibration, and supervisory control. Results are also presented of a demonstration project that involves identifying and selecting mugs containing household chemicals. Proposals for future development of the humanoid robot are also presented.
Mating Preferences of the Gynogenetic Amazon Molly Differ Between Populations Sympatric with Different Host Species

Gynogenetic species rely on sperm from heterospecifics for reproduction but do not receive genetic benefits from mating because none of the paternal genome is incorporated into offspring. The gynogenetic Amazon molly (Poecilia formosa) is a species of hybrid origins that are sympatric with one of the two parent species that provide sperm for reproduction, P. latipinna or P. mexicana. Amazons should not prefer to mate with one species over the other because sperm from both species will trigger embryogenesis, but mating preferences may be present in Amazons through other mechanisms. Amazons may prefer the more familiar species (males found in sympatry), or Amazons may prefer males with the greatest lateral projection area (LPA), a preference that is present in the parent species and may be retained within the Amazon hybrid genome. We tested association preferences of two populations of Amazons sympatric with either P. mexicana or P. latipinna. We first performed live trials to test whether Amazons preferred one host species over the other and found that neither population of Amazons showed a preference. We then tested whether Amazons preferred sympatric male (familiar) host or the male with the greatest lateral projection area (LPA) using four animated male models that varied in host species and manipulation of LPA. We found Amazons from a population sympatric with P. latipinna showed no variation in their association preference across the different models. In contrast, Amazons from a population sympatric with P. mexicana (naturally small LPA) spent more time associating with the male models that had smaller LPA, which is more familiar to this population of Amazons. We suggest that Amazons may have population differences in mating preferences, where Amazons sympatric with P. latipinna may not show mating preference for host species, but Amazons sympatric with P. mexicana may show preferences for more familiar-shaped males.
Contemporary Issues in Crime and Justice Number 100 September 2006 Malicious Damage to Property Offences in New South Wales

In the 24 months to December 2005 recorded incidents of malicious damage to property increased by eight per cent in NSW. This bulletin provides information about the nature of malicious damage to property incidents through a detailed analysis of police database records and narratives of incidents occurring in 2005. These data reveal that the most frequent targets of malicious damage are private dwellings, private vehicles and commercial buildings, and the most common features damaged at these locations are windows. One in ten malicious damage incidents involve graffiti, and in these cases schools and commercial buildings were often the target. Incidents of malicious damage where police were able to identify an offender typically involve young male offenders and often take place in the evening and on weekends. The median cost of police recorded malicious damage incidents as estimated by the victim is $300.
Crossing lines in medicine.

Several years ago one of us (NED) discussed with an Emory University medical student the temperature-pulse dissociation that is said to be seen occasionally in patients with typhoid fever. We recalled seeing in an old textbook a chart that was similar to that represented by Figure 1. In this figure the pulse rate is represented by the open circles and the temperature by the solid squares. I would like to think this was one of Dr. Osler's patients at the University of Pennsylvania, but it so happens that Osler was in Toronto in August 1887, compiling his chorea data (1). It can be seen in the figure that the rising temperature curve and the falling pulse curve cross. This was known by physicians in the past to be a very bad sign but one that is rarely if ever seen today because of good sanitation and antibioticst. The student was impressed by this small piece of esoterica and said, "Gee, that's a pearl. " Shortly thereafter we were sent an article by Dr. James Pitman, Dean of the School of Medicine of the University of Alabama in Birmingham, in which he predicted that Doomsday in medicine would occur on Friday the 13th in November, 1987 (4). § Figure 2 is taken from Dr. Pitman's paper and is rather complicated. The upper solid line plots the physician's anticipated lifetime income assuming he or she started practice at about age 30 and retired at 65. It can be seen that anticipated incomes began increasing markedly during the late 1960's but began declining sharply in the early 1980's. Writing in 1985, Dr. Pitman predicted that by Doomsday, ". the anticipated lifetime earnings of an individual physician from the practice of medicine . falls below the anticipated income for the average high school teacher. " Indeed, it is possible that his (the physician's) anticipated income may fall below zero so that he may still be practicing medicine but doing something else (e.g., farming, real estate, etc.) for a living. The broken line on this chart represents the Health Care Provider Saturation Index, or HECAPSI. Health care providers have traditionally been
Steady-state auditory evoked potential in children and adolescents

Introduction: The applicability of the Steady-State Auditory Evoked Potential has grown in audiological diagnosis. Objective: To investigate the correlation between the electrophysiological thresholds and behavioural thresholds in individuals with normal hearing and sensorineural hearing loss. Method: We evaluated 25 individuals of both genders aged between 5 and 15 years divided into the following groups: 15 individuals with normal hearing and 10 individuals with moderate and moderately severe sensorineural hearing loss. The individuals were submitted to pure tone audiometry, speech audiometry, acoustic impedance and Steady-State Auditory Evoked Potential. Results: In the group with normal hearing, the maximum thresholds electrophysiological ranged from 19 to 27dBcgNA. In the group with moderate and moderately severe hearing loss the correlation was 0.42 to 0.74. Mean differences in electrophysiological and behavioural thresholds were between –0.3 and 12dB for the normal hearing group, –9 and 2dB in the moderate and moderately hearing loss group. Conclusion: In the group with normal hearing there was no correlation between the electrophysiological and behavioural thresholds, however positive correlation was found in the group with loss of moderate and moderately severe.
Stability conditions for a class of nonlinear dynamical systems

The problem of absolute stability for a certain class of nonlinear systems is investigated by means of the Lyapunov direct method. The necessary and sufficient conditions for existence of Lyapunov's functions of the special form for the systems considered are studied. The results obtained are used for the stability analysis of complex systems in critical cases. An example of the system composed from two interconnected nonlinear oscillators is considered.
Contact mechanics of filled thermoplastic and thermoset polymer systems

This study aims to relate the intrinsic mechanical response of particle-filled polymer glasses to their response in sliding friction. A previous study showed that the frictional properties of unfilled polycarbonate are quantitatively captured by finite element simulations when using a proper constitutive model, i.e. a model that captures the polymers intrinsic mechanical response quantitatively, and a rate-independent friction (stick-slip) model. Single-asperity scratch tests were successfully modeled over a range of scratch velocities and for different indenter-tip geometries. In this thesis we extend these pioneering results to the class of practically more relevant and interesting particle-filled (thermoplastic and thermoset) polymer systems. To that end, hard- and soft-particle filled polycarbonate and epoxy systems are investigated. Starting with polycarbonate (that is over the years fully characterized) as matrix material, hard inorganic (TiO2) and soft rubber (MBS) filled model systems are designed and produced. Their intrinsic response is measured in lubricated uniaxial compression tests. To reveal local events at the interparticle level, three-dimensional representative volume elements (3D-RVEs) are constructed to model the complex microstructure of these systems. Finite element simulations of these 3D-RVEs show that the intrinsic response is captured well but, moreover, they provide insight in the critical local events that lead to global failure. The simulations provide the (homogenized) material parameters that macroscopically describe these particle-filled systems, and that are used in the simulations of their scratch response in sliding friction tests. It is confirmed that by combining a proper constitutive framework with the most simple, rate-independent, friction model, all experiments are appropriately described quantitatively by the numerical simulations. Furthermore, the onset of failure during scratching becomes accessible. The local (homogenized) strains resulting from the scratch simulations can be translated to simulations on the RVE-level that reveal the extent of critical events at the interparticle level. After the successful modeling of filled thermoplastic systems, the focus is next on thermosets. Epoxy-based composites are investigated, designed and produced, since thismatrix is more relevant for coating applications. The intrinsic mechanical response ofthe matrix material, a standard epoxy, is characterized and the material parameters usedin the constitutive model are determined. The model systems filled with either softpolysiloxane rubber particles or hard TiO2 particles are created and tested. It is shownthat the complete methodology as derived and described for polycarbonate is also validfor these thermoset systems. The thesis ends with an onset of designing smart materials, inspired by our findingsfrom the simulations on the microstructures and the scratch tests.
Changes in Colorectal Carcinoma Genomes under Anti-EGFR Therapy Identified by Whole-Genome Plasma DNA Sequencing

Monoclonal antibodies targeting the Epidermal Growth Factor Receptor (EGFR), such as cetuximab and panitumumab, have evolved to important therapeutic options in metastatic colorectal cancer (CRC). However, almost all patients with clinical response to anti-EGFR therapies show disease progression within a few months and little is known about mechanism and timing of resistance evolution. Here we analyzed plasma DNA from ten patients treated with anti-EGFR therapy by whole genome sequencing (plasma-Seq) and ultra-sensitive deep sequencing of genes associated with resistance to anti-EGFR treatment such as KRAS, BRAF, PIK3CA, and EGFR. Surprisingly, we observed that the development of resistance to anti-EGFR therapies was associated with acquired gains of KRAS in four patients (40%), which occurred either as novel focal amplifications (n = 3) or as high level polysomy of 12p (n = 1). In addition, we observed focal amplifications of other genes recently shown to be involved in acquired resistance to anti-EGFR therapies, such as MET (n = 2) and ERBB2 (n = 1). Overrepresentation of the EGFR gene was associated with a good initial anti-EGFR efficacy. Overall, we identified predictive biomarkers associated with anti-EGFR efficacy in seven patients (70%), which correlated well with treatment response. In contrast, ultra-sensitive deep sequencing of KRAS, BRAF, PIK3CA, and EGFR did not reveal the occurrence of novel, acquired mutations. Thus, plasma-Seq enables the identification of novel mutant clones and may therefore facilitate early adjustments of therapies that may delay or prevent disease progression.
Methods of Parallel Experimental Design of Online Automatic Tuning and their Application to Parallel Sparse Matrix Data Structure

Automatic tuning is one of key technologies in high performance computing, where parallel processing is essential. In this paper, we propose some methods of parallel experimental design for online automatic tuning of parallel programs. In parallel processing, two kinds of tuning should be investigated. One is local tuning, which optimizes local tuning parameters on each processor, and the other is global tuning, that affects executions of all processors. This paper deals with local tuning, and proposes three methods. The first method we consider is SEO (Serial Experiments Once), where each processor once measures the performance of all the candidates. The second method is PEO (Parallel Experiments Once), where the candidates are evaluated in a distributed manner over the parallel processors. Each processor observes the performance of a subset of the candidates that are assigned to it. Then the performance results are collected, and the candidate of the best performance is chosen. The third method is MPEO (Modified PEO), where each processor can replace the candidate chosen by PEO if it performs badly. Pros and cons of those methods are discussed, and results of application of those methods to an online optimization of parallel sparse matrix data structure are shown.

Role of Cytokine-Induced Glycosylation Changes in Regulating Cell Interactions and Cell Signaling in Inflammatory Diseases and Cancer

Glycosylation is one of the most important modifications of proteins and lipids, and cell surface glycoconjugates are thought to play important roles in a variety of biological functions including cell-cell and cell-substrate interactions, bacterial adhesion, cell immunogenicity and cell signaling. Alterations of glycosylation are observed in number of diseases such as cancer and chronic inflammation. In that context, pro-inflammatory cytokines have been shown to modulate cell surface glycosylation by regulating the expression of glycosyltransferases involved in the biosynthesis of carbohydrate chains. These changes in cell surface glycosylation are also known to regulate cell signaling and could contribute to disease pathogenesis. This review summarizes our current knowledge of the glycosylation changes induced by pro-inflammatory cytokines, with a particular focus on cancer and cystic fibrosis, and their consequences on cell interactions and signaling.
Finite element simulation of ferromagnetic shape memory alloys using a revised constitutive model

In this article, a previously developed constitutive model for ferromagnetic shape memory alloys is phenomenologically enhanced using experimental observations. A modified phase diagram along with a method for calibration of the required model parameters is further presented. The model is implemented into a user material subroutine to equip commercial finite element software ABAQUS with the capability of simulating magneto-mechanical behaviors of ferromagnetic shape memory alloys. A combined convergence scheme is employed to solve the implicit equations. The proposed model together with the presented numerical solution is shown to be able to study shape memory effect and pseudoelasticity at different constant magnetic fields. The simulated magnetic loading/unloading cycles at different constant stresses are found to be well-fitted to the experimental findings. As a practical application of the ferromagnetic shape memory alloy coupled magneto-mechanical response, a spring actuator (a bias spring serially connected to one ferromagnetic shape memory alloy element) is investigated, and the numerical predictions are shown to be in a good agreement with available experimental results. As a novel case, geometrically graded NiMnGa elements are also introduced and are simulated with the use of this approach.
Pattern and keyword based opinion analysis from opinionated texts

In this paper we present an approach to identify opinion of web users from opinionated texts and to classify web users opinion into positive or negative. It is found that a few opinionated texts even though opinionated yields values that are classified neither as positive nor as negative by opinion detection algorithm. When an opinionated text is subjected to opinion detection algorithm, it yields a value that is lesser or greater or equal to the threshold. If it is less than the threshold, it is classified as negative opinion. If it is greater than the threshold, it is classified as positive opinion. If it is equal to the threshold, it is considered as neutral opinion. Different approaches can be considered to obtain opinion from these computed neutral texts so as to classify texts efficiently as positive or negative. We propose the use of pattern and keyword based approach for detection and classification of users opinion from opinionated texts. Our approach is effective in detecting opinion and reducing in-correct classifications. It is found to better than the other implemented methods on different data sets.
Effectiveness of Link Prediction for Face-to-Face Behavioral Networks

Research on link prediction for social networks has been actively pursued. In link prediction for a given social network obtained from time-windowed observation, new link formation in the network is predicted from the topology of the obtained network. In contrast, recent advances in sensing technology have made it possible to obtain face-to-face behavioral networks, which are social networks representing face-to-face interactions among people. However, the effectiveness of link prediction techniques for face-to-face behavioral networks has not yet been explored in depth. To clarify this point, here we investigate the accuracy of conventional link prediction techniques for networks obtained from the history of face-to-face interactions among participants at an academic conference. Our findings were (1) that conventional link prediction techniques predict new link formation with a precision of 0.30–0.45 and a recall of 0.10–0.20, (2) that prolonged observation of social networks often degrades the prediction accuracy, (3) that the proposed decaying weight method leads to higher prediction accuracy than can be achieved by observing all records of communication and simply using them unmodified, and (4) that the prediction accuracy for face-to-face behavioral networks is relatively high compared to that for non-social networks, but not as high as for other types of social networks.
Eight Weeks of Kettlebell Swing Training Does not Improve Sprint Performance in Recreationally Active Females

The kettlebell swing (KBS), emphasizing cyclical, explosive hip extension in the horizontal plane, aligns with movement- and velocity-specificity of sprinting. The present study examined the effect of an eight-week KBS intervention on sprinting in recreationally-active females, in comparison to an eight-week intervention using the stiff-legged deadlift (SDL). Following a pre-testing session measuring 30 meter sprint and countermovement vertical jump performance, participants were divided evenly by sprint time into KBS (n=8) and SDL (n=10) cohorts. Following familiarization with the exercises, KBS met twice weekly to perform swings using the Tabata interval (20s work, 10s rest, 8 rounds), stressing a rapid, explosive tempo. In contrast, the SDL group performed their Tabata stiff-legged deadlifts at a conventional resistance training tempo (2 seconds concentric, 2 seconds eccentric). Following eight weeks and greater than 95% training adherence, the SDL group only had a slightly greater average training volume (~3%) than KBS. No significant differences in pre-test values, or changes were noted in sprint performance from pre- to post-intervention in either group. An improvement in vertical jump performance was noted across groups. Potential explanations for the lack of sprint improvement compared to previous studies include differences between recreationally-active and athletic females, and low exercise volume (~46% of a comparable study with improvements in vertical jump). Future studies should seek to determine the appropriate volume and intensity for KBS components of sprint programming.
