A Bad Attitude and A Bad Stomach: The Soma in Oscar “Zeta” Acosta’s The Autobiography of a Brown Buffalo

Author(s): Fetta, Stephanie | Abstract: What does constipation and bleeding ulcers have to do with racialization? How do such ailments mark the makings of a fine writer? In this article, Fetta takes a transdisciplinary approach utilizing literary analysis, social science, and biological studies, to investigate the effects of racialization on the soma--the intelligent, communicative body-- in the Chicano activist/writer Oscar ‘Zeta’ Acosta’s masterwork The Autobiography of a Brown Buffalo (1971). Fetta develops her theory for somatic analysis in her upcoming monograph: Shame Hurts: Pain in Racialization Through a Somatic Lens in Latino Literature, but in this article, Fetta specifically analyzes Oscar’s stomach as interlocutor, an intelligent entity informing Oscar’s perception of self and society. Fetta argues Oscar engages his digestive disorders in somatic protest against Oscar’s marginalization in US society. At the same time, his visceral disarray defines Oscar with the sensibility of a great Western writer
Learning human motion feedback with neural self-organization

The correct execution of well-defined movements in sport disciplines may increase the body's mechanical efficiency and reduce the risk of injury. While there exists an extensive number of learning-based approaches for the recognition of human actions, the task of computing and providing feedback for correcting inaccurate movements has received significantly less attention in the literature. We present a learning system for automatically providing feedback on a set of learned movements captured with a depth sensor. The proposed system provides visual assistance to the person performing an exercise by displaying real-time feedback to correct possible inaccurate postures and motion. The learning architecture uses recursive neural network self-organization extended for predicting the correct continuation of the training movements. We introduce three mechanisms for computing feedback on the correctness of overall movement and individual body joints. For evaluation purposes, we collected a data set with 17 athletes performing 3 powerlifting exercises. Our results show promising system performance for the detection of mistakes in movements on this data set.
Visualization of the Activity of Rac1 Small GTPase in a Cell

Rho family G proteins including Rac regulate a variety of cellular functions, such as morphology, motility, and gene expression. Here we developed a fluorescence resonance energy transfer-based analysis in which we could monitor the activity of Rac1. To detect fluorescence resonance energy transfer, yellow fluorescent protein fused Rac1 and cyan fluorescent protein fused Cdc42-Rac1-interaction-binding domain of Pak1 protein were used as intermolecular probes of FRET. The fluorophores were separated with linear unmixing method. The fluorescence resonance energy transfer efficiency was measured by acceptor photobleaching assisted assay. With these methods, the Rac1 activity was visualized in a cell. The present findings indicate that this approach is sensitive enough to achieve results similar to those from ratiometric fluorescence resonance energy transfer analysis.
The Pseudomonas aeruginosa Universal Stress Protein PA4352 Is Essential for Surviving Anaerobic Energy Stress

ABSTRACT During infection of the cystic fibrosis (CF) lung, Pseudomonas aeruginosa microcolonies are embedded in the anaerobic CF mucus. This anaerobic environment seems to contribute to the formation of more robust P. aeruginosa biofilms and to an increased antibiotic tolerance and therefore promotes persistent infection. This study characterizes the P. aeruginosa protein PA4352, which is important for survival under anaerobic energy stress conditions. PA4352 belongs to the universal stress protein (Usp) superfamily and harbors two Usp domains in tandem. In Escherichia coli, Usp-type stress proteins are involved in survival during aerobic growth arrest and under various other stresses. A P. aeruginosa PA4352 knockout mutant was tested for survival under several stress conditions. We found a decrease in viability of this mutant compared to the P. aeruginosa wild type during anaerobic energy starvation caused by the missing electron acceptors oxygen and nitrate. Consistent with this phenotype under anaerobic conditions, the PA4352 knockout mutant was also highly sensitive to carbonyl cyanide m-chlorophenylhydrazone, the chemical uncoupler of the electron transport chain. Primer extension experiments identified two promoters upstream of the PA4352 gene. One promoter is activated in response to oxygen limitation by the oxygen-sensing regulatory protein Anr. The center of a putative Anr binding site was identified 41.5 bp upstream of the transcriptional start site. The second promoter is active only in the stationary phase, however, independently of RpoS, RelA, or quorum sensing. This is the second P. aeruginosa Usp-type stress protein that we have identified as important for survival under anaerobic conditions, which resembles the environment during persistent infection.
A Phosphoinositide Synthase Required for a Sustained Light Response

Drosophila phototransduction serves as a model for phosphoinositide (PI) signaling and for characterizing the mechanisms regulating transient receptor potential (TRP) channels in vivo. Activation of TRP and TRP-like (TRPL) requires hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2), resulting in the generation of inositol 1,4,5-trisphosphate (IP3) and diacylglycerol (DAG). Although a role for IP3 has been excluded, TRP channels have been proposed to be activated by either a reduction of inhibitory PIP2 or production of DAG/polyunsaturated fatty acids. Here, we characterize a protein, phosphatidylinositol synthase (dPIS), required for a key step during PIP2 regeneration, the production of phosphatidylinositol. Overexpression of dPIS suppressed the retinal degeneration resulting from two other mutations affecting PIP2 cycling, rdgB (retinal degeneration B) and cds (CDP-diacylglycerol synthase). To characterize the role of dPIS, we generated a mutation in dpis, which represented the first mutation in a gene encoding a PI synthase in an animal. In contrast to other mutations that reduce PIP2 regeneration, the dpis1 mutation eliminated all PI synthase activity in flies and resulted in lethality. In mosaic animals, we found that dPIS was essential for maintaining the photoresponse. Because the dpis1 mutation eliminates production of an enzyme essential for PIP2 regeneration, our data argue against activation of TRP and TRPL through a reduction of inhibitory PIP2.
A kinematics and kinetic comparison of overground and treadmill running.

PURPOSE The purpose of this study was to compare the kinematic and kinetic parameters of treadmill running to those of overground running. METHODS Twenty healthy young subjects ran overground at their self-selected moderate running speed. Motion capture and ground reaction force (GRF) data for three strides of each limb were recorded and the subjects' average running speed was evaluated. The subjects then ran on an instrumented treadmill set to their average overground running speed while motion capture and GRF data were recorded. The kinematics (body segment orientations and joint angles) and kinetics (net joint moments and joint powers) for treadmill (15 consecutive gait cycles) and overground running (three cycles each limb) were calculated and compared. RESULTS The features of the kinematic and kinetic trajectories of treadmill gait were similar to those of overground gait. Statistically significant differences in knee kinematics,the peak values of GRF, joint moment, and joint power trajectories were identified. DISCUSSION Parameters measured with an adequate instrumented treadmill are comparable to but not directly equivalent to those measured for overground running. With such an instrument, it is possible to study the mechanics of running under well-controlled and reproducible conditions. SIGNIFICANCE Treadmill-based analysis of running mechanics can be generalized to overground running mechanics, provided the treadmill surface is sufficiently stiff and belt speed is adequately regulated.
A first evaluation study of a database of kinetic facial expressions (DaFEx)

In this paper we present DaFEx (Database of Facial Expressions), a database created with the purpose of providing a benchmark for the evaluation of the facial expressivity of Embodied Conversational Agents (ECAs). DaFEx consists of 1008 short videos containing emotional facial expressions of the 6 Ekman's emotions plus the neutral expression. The facial expressions were recorded by 8 professional actors (male and female) in two acting conditions ("utterance" and "no- utterance") and at 3 intensity levels (high, medium, low). The properties of DaFEx were studied by having 80 subjects classify the emotion expressed in the videos. High rates of accuracy were obtained for most of the emotions displayed. We also tested the effect of the intensity level, of the articulatory movements due to speech, and of the actors' and subjects' gender, on classification accuracy. The results showed that decoding accuracy decreases with the intensity of emotions; that the presence of articulatory movements negatively affects the recognition of fear, surprise and of the neutral expression, while it improves the recognition of anger; and that facial expressions seem to be recognized (slightly) better when acted by actresses than by actors.
Exposure to Electrical Contact Currents and the Risk of Childhood Leukemia

Abstract The objectives of this study were to examine the association between contact current exposure and the risk of childhood leukemia and to investigate the relationship between residential contact currents and magnetic fields. Indoor and outdoor contact voltage and magnetic-field measurements were collected for the diagnosis residence of 245 cases and 269 controls recruited in the Northern California Childhood Leukemia Study (2000–2007). Logistic regression techniques produced odds ratios (OR) adjusted for age, sex, Hispanic ethnicity, mother's race and household income. No statistically significant associations were seen between childhood leukemia and indoor contact voltage level [exposure ≥90th percentile (10.5 mV): OR = 0.83, 95% confidence interval (CI): 0.45, 1.54], outdoor contact voltage level [exposure ≥90th percentile (291.2 mV): OR = 0.89, 95% CI: 0.48, 1.63], or indoor magnetic-field levels (>0.20 µT: OR = 0.76, 95% CI: 0.30, 1.93). Contact voltage was weakly correlated with magnetic field; correlation coefficients were r = 0.10 (P = 0.02) for indoor contact voltage and r = 0.15 (P = 0.001) for outdoor contact voltage. In conclusion, in this California population, there was no evidence of an association between childhood leukemia and exposure to contact currents or magnetic fields and a weak correlation between measures of contact current and magnetic fields.
Gaze-based teleprosthetic enables intuitive continuous control of complex robot arm use: Writing & drawing

Eye tracking is a powerful mean for assistive technologies for people with movement disorders, paralysis and amputees. We present a highly intuitive eye tracking-controlled robot arm operating in 3-dimensional space based on the user's gaze target point that enables tele-writing and drawing. The usability and intuitive usage was assessed by a “tele” writing experiment with 8 subjects that learned to operate the system within minutes of first time use. These subjects were naive to the system and the task and had to write three letters on a white board with a white board pen attached to the robot arm's endpoint. The instructions are to imagine they were writing text with the pen and look where the pen would be going, they had to write the letters as fast and as accurate as possible, given a letter size template. Subjects were able to perform the task with facility and accuracy, and movements of the arm did not interfere with subjects ability to control their visual attention so as to enable smooth writing. On the basis of five consecutive trials there was a significant decrease in the total time used and the total number of commands sent to move the robot arm from the first to the second trial but no further improvement thereafter, suggesting that within writing 6 letters subjects had mastered the ability to control the system. Our work demonstrates that eye tracking is a powerful means to control robot arms in closed-loop and real-time, outperforming other invasive and non-invasive approaches to Brain-Machine-Interfaces in terms of calibration time (<;2 minutes), training time (<;10 minutes), interface technology costs. We suggests that gaze-based decoding of action intention may well become one of the most efficient ways to interface with robotic actuators - i.e. Brain-Robot-Interfaces - and become useful beyond paralysed and amputee users also for the general teleoperation of robotic and exoskeleton in human augmentation.
A Scrutiny of Automated Healthcare System with Sft

In today's techno savvy world, automated system is very important and contemporary issue. Automated systems are widely used at industries, appliance, automobile, undersea, space and healthcare over the past decade. The accuracy of Robots makes any system more acceptable. Here we use the Robots which assist us to manage patient's heath. We always expect the system must work under any situation. The development of Robotic software is a complex and error prone process. Most complex systems contain software, and systems failures activated by software faults can provide lessons for software development practices and software quality assurance. They must be identified and removed as early as possible. The interrelationship between software faults and failures is quite intricate and obtaining a meaningful characterization. Towards this characterization, we have investigated and classified failures observed in Robotic system. In this paper, we describe the process used in our study for tracking faults. We present the different types of faults, their impact and fault classification. The concern thing is Faults classification and proposed way to manage them. Then we propose the fault tolerance techniques as single to covenant with different faults. Introduction As technically we can say robot as ―A reprogrammable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks"[15].
Adoption of Cardiovascular Risk Reduction Guidelines: A Cluster-Randomized Trial

BACKGROUND AND OBJECTIVES: Cardiovascular disease (CVD) and underlying atherosclerosis begin in childhood and are related to CVD risk factors. This study evaluates tools and strategies to enhance adoption of new CVD risk reduction guidelines for children. METHODS: Thirty-two practices, recruited and supported by 2 primary care research networks, were cluster randomized to a multifaceted controlled intervention. Practices were compared with guideline-based individual and composite measures for BMI, blood pressure (BP), and tobacco. Composite measures were constructed by summing the numerators and denominators of individual measures. Preintervention and postintervention measures were assessed by medical record review of children ages 3 to 11 years. Changes in measures (pre–post and intervention versus control) were compared. RESULTS: The intervention group BP composite improved by 29.5%, increasing from 49.7% to 79.2%, compared with the control group (49.5% to 49.6%; P < .001). Intervention group BP interpretation improved by 61.1% (from 0.2% to 61.3%), compared with the control group (0.4% to 0.6%; P < .001). The assessment of tobacco exposure or use for 5- to 11-year-olds in the intervention group improved by 30.3% (from 3.4% to 49.1%) versus the control group (0.6% to 21.4%) (P = .042). No significant change was seen in the BMI or tobacco composites measures. The overall composite of 9 measures improved by 13.4% (from 48.2% to 69.8%) for the intervention group versus the control group (47.4% to 55.2%) (P = .01). CONCLUSIONS: Significant improvement was demonstrated in the overall composite measure, the composite measure of BP, and tobacco assessment and advice for children aged 5 to 11 years.
THE USAGE OF RADAR IMAGES IN OIL SPILL DETECTION

Discharge of oil including with the tanker accidents have the most dangerous and hazardous effects on marine environment. It is specified that annually more than 4.5 million tons of oil based disposals are poured out to the sea worldwide. The main waste source is the ship based operational discharges with an approximate %45 percentage.The world’s %28 petroleum transfer passes through Mediterranean which makes the %50 of all the transfers in Mediterranean as risky and dangerous. Therefore Turkey, with its surrounded coasts and heavy tanker traffic, is under risk of petroleum hazard. An oil spill monitoring and detection system should be used to prevent and interfere immediately.In order to interfere the oil spill, it is important to identify the type, aerial extent, position, (nearest ship position if any), the possibility percentage etc. For this purpose, satellite-based oil pollution monitoring systems are being used to take precautions and even to determine the possible polluter. Today, Synthetic Aperture Radar (SAR) satellites are the main data sources to detect the oil spills discharged into the sea with sufficient accuracies. In this study, the advantages and disadvantages of using different radar images for oil spill detection in Marmara Sea were investigated.
A Distributed Sensing System for Vehicles State Estimation

This paper presents the design of a distributed sensing system that uses an Extended Kalman Filter (EKF) to fuse measurements, so that automotive vehicle states can be estimated for use by a Semi-active Suspension control system. To improve ride comfort and handling quality, relative displacements and velocities of suspension systems are estimated. To control the stability of vehicles, roll, yaw, and pitch must also be determined. The designed (EKF) uses easily accessible measurements such as accelerations and body's angular velocities. These measurements are provided by 8 accelerometers and an Inertial Measurement Unit (IMU). The accelerometers are strategically mounted on the two ends of each individual shock absorber (damper). The IMU was mounted near the vehicle's center of gravity. Computer simulations and experiments were conducted for full vehicle state estimation of a 1993 Toyota Tercel equipped with the above mentioned sensor suite. Results show that except relative displacements, all states of the automobile's semi-active suspension systems can be estimated using this set of sensors. The designed EKF works well despite not knowing accurate information about road inputs, external disturbances and car characteristics such as moments of inertia, mass, and equivalent spring and damping coefficients. Both simulation results and experimental results show the effectiveness of the designed EKF in estimating the required states. © 2006 ASME
Associations between Infant Feeding Practice Prior to Six Months and Body Mass Index at Six Years of Age

Rapid growth during infancy is associated with increased risk of overweight and obesity and differences in weight gain are at least partly explained by means of infant feeding. The aim was to assess the associations between infant feeding practice in early infancy and body mass index (BMI) at 6 years of age. Icelandic infants (n = 154) were prospectively followed from birth to 12 months and again at age 6 years. Birth weight and length were gathered from maternity wards, and healthcare centers provided the measurements made during infancy up to 18 months of age. Information on breastfeeding practices was documented 0–12 months and a 24-h dietary record was collected at 5 months. Changes in infant weight gain were calculated from birth to 18 months. Linear regression analyses were performed to examine associations between infant feeding practice at 5 months and body mass index (BMI) at 6 years. Infants who were formula-fed at 5 months of age grew faster, particularly between 2 and 6 months, compared to exclusively breastfed infants. At age 6 years, BMI was on average 1.1 kg/m2 (95% CI 0.2, 2.0) higher among infants who were formula fed and also receiving solid foods at 5 months of age compared to those exclusively breastfed. In a high-income country such as Iceland, early introduction of solid foods seems to further increase the risk of high childhood BMI among formula fed infants compared with exclusively breastfed infants, although further studies with greater power are needed.

Reconstructing security types for automated policy enforcement in FABLE

Providing security at programming language level has received enormous attention in recent years. FABLE is an outstanding language intended to enforce the security policies specified by programmers. In doing so, it employs a rich type system whereby only a program with appropriate labels and policy-function calls can type-check. In this paper, we present a constraint-based type system that enables FABLE to infer security labels. It can also be utilized to correct an ill-typed program by identifying missing policy-function invocations. The point is how to preserve the intended functionality of a program when we add code to satisfy a given policy.
Environmental bio-monitoring with high-throughput sequencing

There is much interest in using high-throughput DNA sequencing methodology to monitor microorganisms, complex plant and animal communities. However, there are experimental and analytical issues to consider before applying a sequencing technology, which was originally developed for genome projects, to ecological projects. Many of these issues have been highlighted by recent microbial studies. Understanding how high-throughput sequencing is best implemented is important for the interpretation of recent results and the success of future applications. Addressing complex biological questions with metagenomics requires the interaction of researchers who bring different skill sets to problem solving. Educators can help by nurturing a collaborative interdisciplinary approach to genome science, which is essential for effective problem solving. Educators are in a position to help students, teachers, the public and policy makers interpret the new knowledge that metagenomics brings. To do this, they need to understand, not only the excitement of the science but also the pitfalls and shortcomings of methodology and research designs. We review these issues and some of the research directions that are helping to move the field forward.
