A PROTOTYPE SYSTEM TO MEASURE THE TRUNK ANGLE IN SAGITAL PLANE

The most prevalent musculoskeletal condition and one of the most disabilities are caused by low back pain. In the low back pain, a large variety of evaluation tools is presented to assess the results of the treatment; therefore, it is important to measure the trunk angle in order to determine the progress during patient’s treatment. In this project, we developed a low cost prototype system for flexion-extension movement to measure the angle of the trunk in sagital plane. The system consists of clothing that is stretchable; a Rubbery Ruler sensor (RRs) attached on clothing, data acquisition system. Inertial Magnetic Unit (IMU) sensor installed on spine is used to calibrate the orientation for the output of RRs twenty times. This system was validated by repeated experiments. The curve equation of the RRs output versus the IMU output is presented. Finally, this curve equation can be used to determine the angle of trunk in the clinical applications.
Nonlinear heat-release/acoustic model for thermoacoustic instability in lean premixed combustors

Lean premixed combustors, such as those used in industrial gas turbines to achieve low emissions, are often susceptible to thermoacoustic combustion instabilities, which manifest themselves as pressure and heat release oscillations in the combustor. These oscillations can result in increased noise and decreased durability due to vibration and flame motion. A physically based nonlinear parametric model has been developed that captures this instability. It describes the coupling of combustor acoustics with the rate of heat release. The model represents this coupling by accounting for the effect of acoustic pressure fluctuations on the varying fuel/air ratio being delivered to the flame, causing a fluctuating heat release due to both fuel air ratio variations and flame front oscillations. If the phasing of the fluctuating heat release and pressure are proper, an instability results that grows into a limit cycle. The nonlinear nature of the model predicts the onset of the instability and additionally captures the resulting limit cycle. Tests of a lean premixed nozzle run at engine scale and engine operating conditions in the UTRC single nozzle rig, conducted under DARPA contract, exhibited instabilities. Parameters from the model were adjusted so that analytical results were consistent with relevant experimental data from this test. The parametric model captures the limit cycle behavior over a range of mean fuel air ratios, showing the instability amplitude (pressure and heat release) to increase and limit cycle frequency to decrease as mean fuel air ratio is reduced.
Mitochondrial Management of Reactive Oxygen Species

Mitochondria in aerobic eukaryotic cells are both the site of energy production and the formation of harmful species, such as radicals and other reactive oxygen species, known as ROS. They contain an efficient antioxidant system, including low-molecular-mass molecules and enzymes that specialize in removing various types of ROS or repairing the oxidative damage of biological molecules. Under normal conditions, ROS production is low, and mitochondria, which are their primary target, are slightly damaged in a similar way to other cellular compartments, since the ROS released by the mitochondria into the cytosol are negligible. As the mitochondrial generation of ROS increases, they can deactivate components of the respiratory chain and enzymes of the Krebs cycle, and mitochondria release a high amount of ROS that damage cellular structures. More recently, the feature of the mitochondrial antioxidant system, which does not specifically deal with intramitochondrial ROS, was discovered. Indeed, the mitochondrial antioxidant system detoxifies exogenous ROS species at the expense of reducing the equivalents generated in mitochondria. Thus, mitochondria are also a sink of ROS. These observations highlight the importance of the mitochondrial antioxidant system, which should be considered in our understanding of ROS-regulated processes. These processes include cell signaling and the progression of metabolic and neurodegenerative disease.
De novo assembly and functional annotation of blood transcriptome of loggerhead turtle, and in silico characterization of peroxiredoxins and thioredoxins

The aim of this study was to generate and analyze the atlas of the loggerhead turtle blood transcriptome by RNA-seq, as well as identify and characterize thioredoxin (Tnxs) and peroxiredoxin (Prdxs) antioxidant enzymes of the greatest interest in the control of peroxide levels and other biological functions. The transcriptome of loggerhead turtle was sequenced using the Illumina Hiseq 2000 platform and de novo assembly was performed using the Trinity pipeline. The assembly comprised 515,597 contigs with an N50 of 2,631 bp. Contigs were analyzed with CD-Hit obtaining 374,545 unigenes, of which 165,676 had ORFs encoding putative proteins longer than 100 amino acids. A total of 52,147 (31.5%) of these transcripts had significant homology matches in at least one of the five databases used. From the enrichment of GO terms, 180 proteins with antioxidant activity were identified, among these 28 Prdxs and 50 putative Tnxs. The putative proteins of loggerhead turtles encoded by the genes Prdx1, Prdx3, Prdx5, Prdx6, Txn and Txnip were predicted and characterized in silico. When comparing Prdxs and Txns of loggerhead turtle with homologous human proteins, they showed 18 (9%), 52 (18%) 94 (43%), 36 (16%), 35 (33%) and 74 (19%) amino acid mutations respectively. However, they showed high conservation in active sites and structural motifs (98%), with few specific modifications. Of these, Prdx1, Prdx3, Prdx5, Prdx6, Txn and Txnip presented 0, 25, 18, three, six and two deleterious changes. This study provides a high quality blood transcriptome and functional annotation of loggerhead sea turtles.
DURABILIDAD DE LA MADERA DEL Pinus taeda L. IMPREGNADO CON ARSENIATO DE COBRE CROMATADO, FRENTE A HONGOS XILÓFAGOS, MISIONES, ARGENTINA

The objective of this work was to study the behavior of Pinus taeda L. wood without and with impregnation with retentions of 5, 10 and 15 kg/m 3 of chromated copper arsenate, type C, preservative against Pycnoporus sanguineus, Laetiporus sulphureus, Plerotus sajor caju, Ganoderma applanatum, Glophyllum sp. in laboratory conditions. The wood was obtained from six trees chosen at random, and impregnated with C.C. A. in laboratory autoclave. To determine the efficiency of preservative 5 samples were used 5 samples of 3x 1 x 0,5 cm of no treated wood, were used. The wood samples were sterilized and put on a xylophagaus fungi staying in oven at 28°C for 12 weeks; after this period, the samples were taken away and put on a laboratory environment, until the moisture content of the beginning of the experiment was attained. The degradation was evaluated through the weight loss. The Pinus taeda L. wood was moderately resistant with retentions of 5 and 10 kg/m 3 of CCA, therefore retention of 5 kg/m 3 is enough.

The universal magnetic tunnel junction logic gates representing 16 binary Boolean logic operations

The novel devices are expected to shift the paradigm of a logic operation by their own nature, replacing the conventional devices. In this study, the nature of our fabricated magnetic tunnel junction (MTJ) that responds to the two external inputs, magnetic field and voltage bias, demonstrated seven basic logic operations. The seven operations were obtained by the electric-field-assisted switching characteristics, where the surface magnetoelectric effect occurs due to a sufficiently thin free layer. The MTJ was transformed as a universal logic gate combined with three supplementary circuits: A multiplexer (MUX), a Wheatstone bridge, and a comparator. With these circuits, the universal logic gates demonstrated 16 binary Boolean logic operations in one logic stage. A possible further approach is parallel computations through a complimentary of MUX and comparator, capable of driving multiple logic gates. A reconfigurable property can also be realized when different logic operations are produced from different.
The Role of Augmented Feedback on Motor Learning: A Systematic Review

In motor learning, augmented feedback (AF) is the information provided by sources outside the body and encompasses visual feedback, auditory feedback, and multimodal augmented feedback. This review aims to examine the most recent evidence on these different modality types in healthy and diseased populations and athletes. The reporting of this review was guided by the standards of the “Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA)” statement with the aim to examine the most recent evidence on these feedback types in healthy and diseased populations and athletes. The literature search for this review has been limited to electronic journals with the search engines ISI Web of Knowledge, OvidSP EMBASE, and PubMed databases. This review considers visual feedback as the cornerstone of all augmented feedback types by citing its superiority in learning complex skills by medical students and balance maintenance by older adults. The review also deciphers the role of auditory augmented feedback in encumbering already burdened visual connections in the rehabilitation of patients with Parkinson’s disease (PD) and prosthetic limbs and further argues why the multimodal feedback model seems to be the most efficient way to offer feedback in learning motor tasks by alluding to multifaceted “skill training communication model” in the prevention of sports injuries such as anterior cruciate ligament tears. Multimodal augmented feedback seems to be the most effective and appropriate way to give feedback during motor learning in healthy and diseased populations and athletes as its stimuli are perceived faster and tend to be retained longer compared with the unimodal stimuli of auditory and visual feedback mechanisms.
StoryScape : fun technology for supporting learning, language and social engagement through story craft

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder that a↵ects approximately 1-in-68 persons and 1-in-42 boys. Challenges related to communication form a core characteristic of the ASD condition. Literature suggests the single most important prognostic indicator for young children diagnosed with ASD is communication ability. Yet, engaging children diagnosed with ASD in communication centered activities is one of the cardinal challenges presented by the condition and contributes to poor outcome. This work explores the development, implementation and testing of StoryScape, a platform for engaging children diagnosed with ASD in communication centered activities. Through extensive work with the ASD community, I have sought to develop a more holistic learning technology around communication. The StoryScape platform connects web, mobile, and physical technologies through interactive stories, enabling fun and engaging learning through story creation and other activities. While the main focus of this work is related to children diagnosed with ASD, I also present a number of exploratory studies conducted with neurotypical children. In total, six exploratory studies, three with children diagnosed with ASD and three with neurotypical children, are presented. These studies demonstrate the many uses of StoryScape, and were critical for eliciting feedback on usability and design features during its iterative development. In addition, I present the results from a seven-week study of story co-creation, conducted as a whole-class activity with students diagnosed with ASD. Results show a statistically significant increase in vocal expressions during use of StoryScape. Students also demonstrate a strong preference for the StoryScape activity compared to other activities. Teachers reported being surprised by the high level of student engagement and cooperation with each other, and they reported that students looked forward to using StoryScape daily. While teachers reported meaningful communication improvements during use of StoryScape for all of their students, one student was described by his teacher as “a totally di↵erent student when using StoryScape. ” Thesis Supervisor: Rosalind Picard Title: Professor of Media Arts and Sciences, Massachusetts Institute of Technology
Charge-Based Formulation of Thermal Noise in Short-Channel MOS Transistors

In this communication we develop a charge-based formulation for the thermal noise in short-channel transistors. We arrive at a closed expression for the channel thermal noise including the velocity saturation effect for all the operating regions of the MOSFET. Such a result is increasingly important not only in strong inversion but also in moderate and weak inversion owing to technology scaling into the deep submicron regime. We based the calculation of the thermal noise on the impedance field method [4], which allows calculating the effect of local fluctuations on the measurable noise at the device terminals. Our derivation follows the same procedure used in [2], but rather than constraining the result to strong inversion, our quite general result is expressed in terms of the inversion charge densities at the source and drain terminals.
Accurate modeling for parasitic source resistance in two-dimensional electron gas field-effect transistors

An accurate two-layer model has been developed for parasitic source resistance in two-dimensional electron gas field-effect transistors (2DEGFETs). In this model, the 2DEG concentration-voltage and current density-voltage relations at the cap/barrier/2DEG junction are taken into account, based on the self-consistent charge control model and effective mass tunneling theory. Empirical 2DEG velocity field characteristics are also included. To show the feasibility of this method, the source resistance in conventional GaAs/AlGaAs 2DEGFETs was analyzed and the AlGaAs thickness dependence was discussed. For comparison, the lattice-matched GaInAs/AlInAs 2DEGFET and pseudomorphic GaInAs/AlGaAs 2DEGFET were examined. It was shown that introducing a highly doped cap layer leads to a drastic reduction in source resistance for pseudomorphic 2DEGFETs but has a very small effect for GaInAs/AlGaAs 2DEGFETs. >
Survey on Methods for Investigating Protein Functionality and Related Molecular Characteristics

Proteins from various sources are widely used in the food industry due to their unique functional performances in food products. The functional properties of proteins are somehow dictated by their molecular characteristics, but the exact relationship is not fully understood. This review gives a tangible overview of the methods currently available for determining protein functionality and related molecular characteristics in order to support further research on protein ingredients. The measurements of protein functionality include solubility, water holding capacity, oil holding capacity, emulsion property, foam property, and gelation. This review also provides a description of different methods of molecular characteristics including electrophoresis, surface hydrophobicity and charge, molecular interaction, and thermal property measurement. Additionally, we have put significant emphasis on spectroscopic methods (ultraviolet-visible, Fourier transform infrared, Raman, circular dichroism, fluorescence and nuclear magnetic resonance). In conclusion, first and foremost, there is a need to agree on a standardization of the analytical methods for assessing functional properties. Moreover, it is mandatory to couple different analyses of molecular characteristics to measure and monitor the structural changes obtained by different processing methods in order to gain knowledge about the relationship with functionality. Ideally, a toolbox of protein analytical methods to measure molecular characteristics and functionality should be established to be used in a strategic design of protein ingredients.
Cold comfort in a high carbon society?

It is now obvious that technology and society co-evolve. This should lead to increasing collaboration between social scientists and engineers in fields such as buildings. Yet engineering insights still have hegemony over building practices and the setting of standards. This paper considers how the insights from the recent Building Research & Information 2008 special issue titled ‘Comfort in a Lower Carbon Society’ might be applied in the building sector and in associated policy-making processes. It concludes that economics, the dominant discipline in the policy world, tells us that there is a huge prize to be gained in terms of reducing carbon emissions in the built environment, but that it does not provide many clues about the practical steps needed to secure the prize. Social science insights could be critical here. Specifically, it is argued that social science can increase one's understanding of the ways in which needs and demand for comfort are created. It can help design regulatory processes that build in visions of a lower carbon society from the start. It also provides the insight that high-level policy-makers must send coherent signals to regulators and practitioners to avoid the low carbon building agenda coming into conflict with other policy goals. Il est évident, aujourd'hui, que la technologie et la société évoluent ensemble. Cela devrait conduire à une collaboration plus étroite entre chercheurs sociaux et ingénieurs dans des domaines tels que la construction. Or, l'information technique prend toujours le pas sur les pratiques du bâtiment et sur l'élaboration de normes. Cet article étudie comment les idées contenues dans le numéro spécial de Building Research & Information 2008 consacré au confort dans une société sobre en carbone pourraient être appliquées au secteur du bâtiment et aux procédures décisionnelles associées. L'auteur conclut que l'économie, la discipline dominante du monde politique, nous indique qu'il y aurait beaucoup à gagner en termes de réduction des émissions de carbone dans le milieu bâti mais il ne donne aucune piste sur les mesures pratiques nécessaires pour sécuriser cet avantage. Les idées qui circulent dans les sciences sociales pourraient être critiques à cet égard. De manière spécifique, on fait valoir que les sciences sociales pourraient améliorer la compréhension des solutions dans lesquelles sont créés les besoins et la demande de confort. Elles pourraient aider à définir des procédures régulatrices envisageant dès le départ la perspective d'une société sobre en carbone. Elles indiquent également que les décideurs politiques de haut niveau doivent envoyer des signaux cohérents aux organes de réglementation et aux praticiens pour éviter que les programmes de construction à faible teneur en carbone contredisent d'autres objectifs politiques.

VLCIoT: design and implementation of a visible light communication system for indoor Internet of Things applications.

In this paper, a visible light communication (VLC) system for indoor Internet of Things (IoT) applications, called VLCIoT, is proposed. The proposed system is based on type I of the IEEE 802.15. 7 standard physical (PHY) layer. The PHY I is provided for low data rate applications from 10 to 100 kb/s, which looks suitable for the typical IoT applications. The on-off keying suggested modulation scheme by the PHY I that is simple and requires low-cost hardware for implementation is considered. The implemented VLCIoT system is robust against indoor ambient light interference. Using the frequency division multiple access, several VLC networks can operate at different frequencies in the vicinity of each other without interference. The data rate of VLCIoT is up to 115.2 kb/s, and the bit error ratio of the system is very low. This system is designed for indoor, which for this purpose operates well up to 7 m distances. In this paper, a figure of merit (FoM) is proposed, in which the most important parameters for IoT applications are considered. A comprehensive comparison of VLCIoT to other suitable VLC systems for IoT applications is performed. The results show that the VLCIoT achieves the best FoM and is suitable for indoor IoT applications.
Recent Advances in the Brønsted/Lewis Acid Catalyzed Conversion of Glucose to HMF and Lactic Acid: Pathways toward Bio-Based Plastics

One of the most trending topics in catalysis recently is the use of renewable sources and/or non-waste technologies to generate products with high added value. That is why, the present review resumes the advances in catalyst design for biomass chemical valorization. The variety of involved reactions and functionality of obtained molecules requires the use of multifunctional catalyst able to increase the efficiency and selectivity of the selected process. The use of glucose as platform molecule is proposed here and its use as starting point for biobased plastics production is revised with special attention paid to the proposed tandem Bronsted/Lewis acid catalysts.
Filterbank design for oversampled subband adaptive filtering structures

A simple design procedure for uniform DFT filterbanks used in oversampled subband adaptive filtering structures is presented. The analysis prototype filter is designed with extended bandwidth to obtain fast convergence. The synthesis prototype filter is then optimised to reduce the mean square error. The resulting improvements in the convergence performance are verified through computer simulations.
Passive-heat stress does not induce muscle fatigue, central activation failure or changes in intracortical properties of wrist flexors

This study evaluated the effect of passive-heat stress on the neuromuscular properties of the wrist flexor muscles, which are commonly used in manual labour hand tasks. A combination of techniques were utilised, involving nerve stimulation and paired-pulse transcranial magnetic stimulation to assess changes in muscle strength, contractile properties, fatigue-resistance and central activation as well as indices of intracortical excitability in 10healthy humans who were exposed to a passive heat stress protocol as well as a normothermia control protocol. Passive-heat stress increased core body temperature ∼1°C (37.2 ± 0.4 to 38.2 ± 0.4°C ; p < 0.01), mean skin temperature (34.5 ± 0.7°C to 37.3 ± 1.1°C; p < 0.01), and heart rate (79.5 ± 20.0 to 110.0 ± 23.0 beats/min; p = 0.04). No effect was observed on muscle strength, contractile properties, muscle fatigability, central activation orindices of intracortical excitability (p > 0.05). These data indicate that allowing internal temperatures of workers to increase ≤1.0°C does not affect neuromuscular properties of the wrist flexors. Statement of Relevance: Exercise-heat stress has been shown to reduce human performance and exacerbate muscle fatigue. However, lessis known about passive-heat stress, especially during milder heat stress encountered in many occupational settings. Accordingly, the effect of occupationally relevant passive-heat stress on the neuromuscular properties of thewristflexors was examined.
