Towards a real-time driver identification mechanism based on driving sensing data

The growing penetration of telematics systems and connectivity in vehicles has enabled a large variety of possible value-added services for drivers and service providers. In particular telematics based real-time driver identification is in interest of entities such as insurance companies, car rentals and public transportation fleet managers. We propose a mechanism for driver identification based on driving dynamics signals currently available in production cars. The system collects and filters sensing data in a sliding window iteration, computes statistical and spectral features and finally provides driver identification for each window frame through a classification process. Finally, a decision function takes individual predictions and outputs a single prediction for the ongoing trip. We evaluate the impact of various elements of the process on identification accuracy, including sliding window size, classifier algorithms and feature sets. Results show that complementing gas pedal signal with steering wheel cepstral analysis improves identification accuracy by 22.4%. We also show that Boosting classifiers provide better predictions for our problem and the best results have been achieved using AdaBoost with 95,89,82 percent accuracies for 5,15,35 drivers respectively. In terms of real-time identification performance, the proposed system is able to correctly identify 75% of the drivers in less than 65 s in a 5 drivers scenario.
Nutritional and genetic adaptation of galliform birds: implications for hand-rearing and restocking

The impact of hand-rearing on the morphology and physiology of captive and wild grey partridges (Perdix perdix) and capercaillies (Tetrao urogallus) was studied in three feeding trials conducted under laboratory conditions, and two comparative studies between wild and captive birds. Finally, wild and hand-reared grey partridges from several localities in Europe were sampled and the control region 1 of mitochondrial DNA was sequenced to reveal genetic variation between populations, as well as to compare wild and captive stocks. Wild capercaillies had heavier pectoral muscles, hearts, livers and gizzards, longer small intestines than hand-reared ones, and a higher cytochrome-c oxidase activity in muscle and heart. Invertebrates were essential to the growth, primary and temperature regulation development in grey partridge chicks. Fish was not sufficient to replace invertebrates in the diet. A change in diet from commercial to natural decreased the assimilation efficiency in the grey partridge. It also increased the mass of gizzard reflecting the need for greater grinding ability. Of hepatic P450 enzymes used in this study 7-ethoxyresorufin-0-deethylase and 7-pentoxyresorufin-0-deethylase differed between wild and hand-reared birds. Coumarin-7-hydroxylase activity was higher in grey partridges than capercaillies. Diet differences may have caused these differences. Quebracho tannin added to the diet lowered nitrogen concentration in caecal feces, and elevated the level of excreted tannin. Otherwise its effects were slight. Mitochondrial control region revealed 14 variable sites between two main lineages detected. Nucleotide and haplotype diversities varied greatly between populations. The markedly deep divergence between the two lineages indicated most probably post-glacial recolonisations from geographically isolated refuges. In Finland, wild birds represented the eastern lineage, while the farmstock represented the western lineage. Surprisingly little trace, contrary to expectations, from the large-scale releasing of imported partridges could be seen in the European populations.
Context-sensitive statistical language modeling

We present context-sensitive dynamic classes ‐ a novel mechanism for integrating contextual information from spoken dialogue into a class n-gram language model. We exploit the dialogue system’s information state to populate dynamic classes, thus percolating contextual constraints to the recognizer’s language model in real time. We describe a technique for training a language model incorporating context-sensitive dynamic classes which considerably reduces word error rate under several conditions. Significantly, our technique does not partition the language model based on potentially artificial dialogue state distinctions; rather, it accommodates both strong and weak expectations via dynamic manipulation of a single model.
Improvement of Plated Copper Adhesion in Glass Interposer Applications

Glass interposers offer a compelling alternative to silicon interposers with highest I/Os and excellent electrical performance, with potential for low cost from large panel processing. For sub-32nm IC nodes and 3D-IC packages at fine I/O pitch, organic substrates are reaching their limits in terms of I/Os, design rules and CTE mismatch. Glass offers the best combination of electrical insulation, dimensional stability, CTE match to Si ICs, and flat, smooth surfaces for ultra-fine line lithography. The biggest challenge in glass interposers is the formation and metallization of ultra-fine pitch through vias. The formation of small via diameters in thin glass substrate have been demonstrated. The focus of this paper will be on wet metallization of glass interposer with through via, and addressing the challenge of providing reliable adhesion on the copper-to-glass interface. Two main approaches are currently pursued in the wet-chemical metallization of glass interposers: the electroless and electrolytic coppe.
Ultrasound-Induced New Cellular Mechanism Involved in Drug Resistance

The acoustic effects in a biological milieu offer several scenarios for the reversal of multidrug resistance. In this study, we have observed higher sensitivity of doxorubicin-resistant uterine sarcoma MES-SA/DX5 cells to ultrasound exposure compared to its parent counterpart MES-SA cells; however, the results showed that the acoustic irradiation was genotoxic and could promote neotic division in exposed cells that was more pronounced in the resistant variant. The neotic progeny, imaged microscopically 24 hr post sonication, could contribute in modulating the final cell survival when an apoptotic dose of doxorubicin was combined with ultrasound applied either simultaneously or sequentially in dual-treatment protocols. Depending on the time and order of application of ultrasound and doxorubicin in combination treatments, there was either desensitization of the parent cells or sensitization of the resistant cells to doxorubicin action.
FEM analysis of bonding process used for minimization of deformation of optical surface under Metis coronagraph mirrors manufacturing

High demands on the final surfaces micro-roughness as well as great shape accuracy have to be achieved under the manufacturing process of the precise mirrors for Metis orbital coronagraph. It is challenging engineering task with respect to lightweight design of the mirrors and resulting objectionable optical surface shape stability. Manufacturing of such optical elements is usually affected by number of various effects. Most of them are caused by instability of temperature field. It is necessary to explore, comprehend and consequently minimize all thermo - mechanical processes which take place during mirror cementing, grinding and polishing processes to minimize the optical surface deformation. Application of FEM simulation was proved as a useful tool to help to solve this task. FEM simulations were used to develop and virtually compare different mirror holders to minimize the residual stress generated by temperature changes and to suppress the shape deformation of the optical surface below the critical limit of about 100 nm.
Analysis of Successful Immune Responses in Persons Infected with Hepatitis C Virus

Although hepatitis C virus (HCV) infection is very common, identification of patients during acute infection is rare. Consequently, little is known about the immune response during this critical stage of the disease. We analyzed the T lymphocyte response during and after acute resolving HCV infection in three persons, using interferon (IFN)-γ enzyme-linked immunospot (ELISPOT) and human histocompatibility leukocyte antigen (HLA) peptide tetramer assays. Acute infection was associated with a broadly directed T helper and cytotoxic T lymphocyte (CTL) response, which persisted after resolution of clinical hepatitis and clearance of viremia. At the earliest time point studied, highly activated CTL populations were observed that temporarily failed to secrete IFN-γ, a “stunned” phenotype, from which they recovered as viremia declined. In long-term HCV-seropositive persons, CTL responses were more common in persons who had cleared viremia compared with those with persistent viremia, although the frequencies of HCV-specific CTLs were lower than those found in persons during and after resolution of acute HCV infection. These studies demonstrate a strong and persistent CTL response in resolving acute HCV infection, and provide rationale to explore immune augmentation as a therapeutic intervention in chronic HCV infection.
Serologic Detection of Antibodies Targeting the Leukocidin LukAB Strongly Predicts Staphylococcus aureus in Children With Invasive Infection.

BACKGROUND Staphylococcus aureus is among the most commonly identified causes of invasive bacterial infection in children; however, reliable results from cultures of sterile-site samples often cannot be obtained, which necessitates prescription of a broad empiric antimicrobial agent(s). Children with invasive S aureus infection rapidly generate high antibody titers to the cytotoxin LukAB; therefore, the aim of this study was to assess the diagnostic utility of an anti-LukAB antibody assay for children with musculoskeletal infection (MSKI). METHODS We conducted a 2-year prospective study of all eligible children admitted to Vanderbilt Children's Hospital with an MSKI. Acute and convalescent sera were obtained, and antibodies that target LukAB were measured by an enzyme-linked immunosorbent assay. RESULTS Forty-two children were enrolled. The median concentrations of LukAB antibodies for children with S aureus infection were 130.3 U/mL in the acute phase and 455 U/mL in the convalescent phase (P < .001). The median concentrations of LukAB antibodies in children with a non-S aureus MSKI were 8.6 U/mL in the acute phase and 9.7 U/mL in the convalescent phase. The assay discriminated between S aureus and non-S aureus infection with areas under the receiver operating characteristic curve of 0.81 (95% confidence interval, 0.67-0.95; P < .001) and 0.95 (95% confidence interval, 0.86-1; P < .001) for samples tested in the acute and follow-up periods, respectively. With no false-negative results, the assay accurately ruled out S aureus in samples obtained during the convalescent phase. CONCLUSION Culture-independent diagnostics have the potential to improve care by narrowing antimicrobial therapy on the basis of the likelihood of S aureus infection. The results of this proof-of-concept study suggest that a LukAB serologic assay might be useful in the diagnosis of invasive bacterial infections, and larger-scale validation studies are warranted.
Concurrent treatment of aplastic anemia/paroxysmal nocturnal hemoglobinuria syndrome with immunosuppressive therapy and eculizumab: a UK experience

Paroxysmal nocturnal hemoglobinuria (PNH), an ultraorphan disease with a prevalence of 15.9 per million in Europe, is a life threatening disorder characterized by hemolysis, bone marrow failure and thrombosis. Patients with PNH prior to eculizumab had a median survival of between 10 and 22 years. Eculizumab (Soliris®, Alexion), a fully humanized immunoglobulin G (IgG) monoclonal antibody to C5, is currently the only licensed treatment for PNH. Aplastic anemia and PNH are intimately linked, with 40-60% of patients with aplastic anemia having a PNH clone, albeit often small. Patients are at risk of developing clinical PNH on recovery from aplastic anemia, due to PNH clone expansion. Patients with aplastic anemia should be treated according to current guidelines, depending on disease severity and concomitant health problems. Concurrent treatment of PNH and aplastic anemia is uncommon, with aplastic anemia treatment often predating PNH. There are very few publications as to the best course of treatment for these patients. Single case reports and small case series suggest this is safe, and report a positive outcome when patients are treated as per national guidelines whilst remaining on eculizumab, however there is likely a positive reporting bias.
Driver's decision analysis in terms of pedestrian attributes — A case study in passing by a pedestrian

In this paper, we report a case study on driver's decision in terms of pedestrian attributes. Among various traffic situations, the situation that a vehicle passes by a pedestrian is one of the major situations. To build a safety driving system that supports a non-experienced driver in such a situation, we analyzed how experienced drivers decide to handle the vehicle in such a situation. Since pedestrian's behavior can be considered as a key factor for the decision, and also the behavior is different depending on their “attributes,” such as walking or stopping, noticing the vehicle or not, using a smartphone, etc., we analyzed what pedestrian's attributes affect the driver's decisions. For the analysis, we first built a large-scale dataset of driving data. Using the dataset, we clarified what attributes are dominant for the driver's decision.

Cooperative Communications in Machine to Machine (M2M): Solutions, Challenges and Future Work

The application of cooperative communication (CC) in wireless networks makes it possible for the terminals to hear and aid the transfer of each other’s information to the required destinations. CC utilizes the advantage of the broadcast nature of wireless communications to achieve its objectives. The advantages enjoyed by networks that employ the principles of CC include: improvement of connectivity, improvement in energy utilization, spectrum efficiency, counteracting of the limited per device complexity, and a boost in communication reliability among devices in the network. When CC is compared with other techniques that perform functions similar to it like multiple input multiple output, it has an upper hand due to the fact that CC has a hardware that is feasible and its deployment is more flexible. The implementation of CC in machine to machine (M2M) in this paper is based on the use of relays and clustering protocols. Popular protocols of relays and clustering are presented as solutions, and detailed emerging research challenges that include but are not limited to: escalating complex scheduling design, increased message overheads, increased intra and inter network interferences, increased end-to-end latency, and redundancy are discussed. Future works that includes critical application of full duplex relays, utilization of non-regenerative mode of relay operation, cross layer optimization, application of clustering scheme with reconciling quality-of-service properties, and designing of hybrid clustering techniques are proposed. They are aimed at improving on the challenges and hence foster efficiency in M2M network resources.
Design of user clustering and precoding for downlink non-orthogonal multiple access (NOMA)

In this paper, we propose a novel user clustering algorithm for non-orthogonal multiple access (NOMA) considering the channel correlation between users and the channel gain. We also adopt sum-rate maximization approach to find an optimal precoding matrix in the multi-user multiple-input-multiple-output (MU-MIMO) setup after the user clustering. Grouping two users in a single beam to serve users in a non-orthogonal fashion raises multi-user interference (MUI). To tackle this problem, the clustering algorithm considers the channel correlation to select users aligned with same direction. Furthermore, the channel gain is also reflected in the clustering algorithm to enhance signal-to-interference-plus-noise ratio (SINR) inspired by the fact that the optimal precoding matrix is less sensitive to channel direction. Optimization algorithm over the precoding matrix is proposed based on Majorization Minimization (MM) approach for a non-convex objective function. We demonstrate the superiority of the proposed schemes comparing with conventional ones through numerical results.
Actinomadura barringtoniae sp. nov., an endophytic actinomycete isolated from the roots of Barringtonia acutangula (L.) Gaertn.

A novel actinomycete strain, designated GKU 128T, isolated from the roots of an Indian oak tree [Barringtonia acutangula (L.) Gaertn. ] at Khao Khitchakut district, Chantaburi province, Thailand, was characterized by using a polyphasic approach. The strain formed a branched substrate and aerial mycelia which differentiated into straight to flexuous chains of smooth-ornamented spores. Analysis of the cell wall revealed the presence of meso-diaminopimelic acid and N-acetylmuramic acid in the peptidoglycan. The whole-cell sugars were glucose, madurose, mannose, rhamnose and ribose. Mycolic acids were absent. The major phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositolmannoside. The predominant menaquinones were MK-9(H6), MK-9(H8), MK-9(H0) and MK-9(H4). The major fatty acids were C16 : 0, C18 : 1ω9c and 10-methyl C18 : 0 (tuberculostearic acid). The genomic DNA G+C content was 70.5 mol%. Based on 16S rRNA gene sequence analysis, strain GKU 128T was closely related to the type strains of Actinomadura nitritigenes NBRC 15918T (99.2 % sequence similarity) and Actinomadura fibrosa JCM 9371T (98.7 %). The levels of DNA-DNA relatedness between strain GKU 128T and the closely related type species were less than 19 %. On the basis of phenotypic and genotypic characteristics, strain GKU 128T could be distinguished from its closely related type strains and represents a novel species of the genus Actinomadura, for which the name Actinomadura barringtoniae sp. nov. (=TBRC 7225T=NBRC 113074T) is proposed.
Quantifying muscle patterns and spine load during various forms of the push-up.

PURPOSE This study was conducted to quantify the normalized amplitudes of the abdominal wall and back extensor musculature during a variety of push-up styles. We also sought to quantify their impact on spinal loading by calculating spinal compression and torque generation in the L4-5 area. METHODS Ten university-age participants, nine males and one female, in good to excellent condition, volunteered to participate in this study. All participants were requested to perform a maximum of 12 different push-up exercises, three trials per exercise. Surface electromyographic data (EMG) were collected bilaterally on rectus abdominis, external oblique, internal oblique, latissimus dorsi, and erector spinae muscles, and unilaterally (right side) on pectoralis major, triceps brachii, biceps brachii, and anterior deltoid muscles. Spine kinetics were obtained using an anatomically detailed model of the torso/spine. RESULTS This study revealed that more dynamic push-ups (i.e., ballistic, with hand movement) required more muscle activation and higher spine load, whereas placing labile balls under the hands only resulted in modest increases in spine load. Right rectus abdominis (RA) activation was significantly higher than left RA activation during the left hand forward push-up and vice versa for the right hand forward push-up (P < 0.001). External oblique (EO) demonstrated the same switch in dominance during staggered hand push-ups (P < 0.01). The one-arm push-up resulted in the highest spine compression. Skilled participants showed greater synchronicity with peak muscle activation (plyometric type of contractions) during ballistic push-ups. CONCLUSION These data will help guide exercise selection for individuals with differing training objectives and injury history.
Face Perception and Learning in Autism Spectrum Disorders

Autism Spectrum Disorder (ASD) is characterized by impairment in social communication and restricted and repetitive interests. While not included in the diagnostic characterization, aspects of face processing and learning have shown disruptions at all stages of development in ASD, although the exact nature and extent of the impairment vary by age and level of functioning of the ASD sample as well as by task demands. In this review, we examine the nature of face attention, perception, and learning in individuals with ASD focusing on three broad age ranges (early development, middle childhood, and adolescence/adulthood). We propose that early delays in basic face processing contribute to the atypical trajectory of social communicative skills in individuals with ASD and contribute to poor social learning throughout development. Face learning is a life-long necessity, as the social world of individual only broadens with age, and thus addressing both the source of the impairment in ASD as well as the trajectory of ability throughout the lifespan, through targeted treatments, may serve to positively impact the lives of individuals who struggle with social information and understanding.
Preparation of transparent hydrophobic polymeric films spray-deposited on substrates

This paper describes the production of transparent hydrophobic polymeric films made of poly(vinyl chloride) and paraffin wax. A liquid polymeric solution was prepared and spray-deposited on silica glass and nonwoven fabric surfaces. The contact angle between water droplets and glass substrate was 102° while that between droplets and nonwoven fabric was 120°. The films exhibited hydrophobic behaviour regardless of the droplet size. Field emission gun scanning electron microscopy revealed complete adhesion of the film on the substrate and a film thickness of 0.16 µm. The atomic force microscopy micrographs showed a nanoscale rough film surface, which was responsible for air entrapment, preventing water from penetrating the film. This fact explains the high contact angle obtained. The raw materials also contributed to the film's hydrophobicity because of their non-polarity, which prevents miscibility between water droplets and film. GRAPHICAL ABSTRACT
