Improving Always-On Gesture Recognition Power Efficiency for Android Devices Using Sensor Hubs

In mobile user interaction scenarios, gesture recognition applications often process inertial sensor data and run continuously to reduce latency. In this paper, we evaluate real-life efficiency gains of gesture detection on-loading onto microcontroller-based sensor subsystems (sensor hubs). To this end, we implement smartphone wakeup gestures in two ways: (1) running on the Application Processing Unit (APU) that activates and unlocks the screen of an Android smartphone and (2) running on a sensor hub as interaction composite sensors that can directly wake up the APU through an interrupt line. We show that the sensor hub architecture can massively improve battery life in smartphones over the APU-based app while still enabling these new continuous sensing applications.
Collaborative , Contact-based Schemas for Robot Righting utilizing Hull Shape Design

Nature’s self-organizing teams have long inspired engineering researchers. Imitating birds and fish, researchers built swarms that could keep formation via elegant decentralized control algorithms. Inspired by ants, they applied formation keeping to carrying loads as a mobile robot team. In this work, we further specialize this collaborative manipulation to manipulating teammates, thereby creating collaborative locomotion. Our design space is enriched by designing both the manipulator and the manipulatee at the same time. Traditional collaborative manipulation work focuses on manipulating objects in the same plane of movement as the mobile robots and adheres strictly to form or force closure manipulation paradigms. Our new design richness allows us to leverage work on in-hand, dexterous manipulation and dynamic manipulation techniques to manipulate objects (now teammates) in degrees of freedom (DOF) outside our plane of movement. These further manipulation DOF are accessed by especial care in designing the contact surfaces between robots which allows us to guide objects while slipping, instead of rigidly demanding complete closure. This paper will demonstrate the collaborative locomotion concept in the simplest possible cooperative maneuver: rolling a pronated robot back onto its feet (adding a previously inaccessible roll DOF to a differentially driven robot). Within this showcase application we discover several possible designs for cooperative righting strategies. The strategies follow the traditional manipulation classification framework: kinematic, quasi-static, and dynamic. We investigate each method analytically as well as implementing the best method on real robots. 0.
Thalamo‐cortical processing of near‐threshold somatosensory stimuli in humans

Somatosensory stimuli elicit complex cortical responses that are discernible as somatosensory evoked potentials (SEPs) in scalp electroencephalographic recordings. Whereas earlier SEP components, occurring up to 100 ms after stimulus delivery, have been labeled ‘preconscious’, later responses have been associated with stimulus awareness. To date, how far these processes are primarily cortical or comprise additional subcortical operations remains open. Therefore, we recorded thalamic and scalp SEPs evoked by perceived as well as unperceived median nerve stimulation in neurosurgical patients with electrodes implanted into the ventral intermediate nucleus of the thalamus for deep brain stimulation. At stimulation intensities below perceptual threshold, only thalamic SEP components appeared consistently during the first 75 ms after stimulus delivery. Stimulation that was perceived by the patients elicited cortical as well as thalamic SEPs that lasted longer than 75 ms. These results indicate that the thalamus remains active after the primary propagation of a sensory signal to the cortex, and suggest that the transition from elementary to higher‐order somatosensory processing is based on thalamo‐cortical interactions.
X-ray Based Planning of Implant-Prosthetic Treatment for Oncological Patients after Post-Resective Maxilla / Mandible Reconstruction-Quantitative Evaluation of Implantation Results

The aim of this work was to develop a tool for X-ray based planning of implant-prosthetic treatment for oncological patients after post-resective maxilla or mandible reconstruction. To extend the possibilities of the currently developed system, in cooperation with oncologists and dentists we designed a module of qualitative analysis of pre and postoperative CT image datasets. The surgeon can fuse pre and postoperative images basing on matching markers identified in both datasets. After a proper transformation, matched datasets can be analysed in order to evaluate applied treatment. Using the software the surgeon can measure such parameters as: the accuracy of implants axes locations and orientations, the diameters, lengths and depth of applied implants in comparison to the designed in preoperative planning. It is rational to apply X-ray images to analyse the efficiency of implantprosthetic treatment, since the oncological patients need to be examined regularly to supervise the risk of neoplasm recurrence. The paper presents also our concept to apply Cone Beam Computed Tomography (CBCT), as a significantly less invasive imaging technique in comparison to the standard CT. The 3D dataset reconstructed will be applied similarly to the currently applied in the software CT.
The E2A-HLF Oncoprotein ActivatesGroucho-Related Genes and SuppressesRunx1

ABSTRACT The E2A-HLF fusion gene, formed by the t(17;19)(q22;p13) chromosomal translocation in leukemic pro-B cells, encodes a chimeric transcription factor consisting of the transactivation domain of E2A linked to the bZIP DNA-binding and protein dimerization domain of hepatic leukemia factor (HLF). This oncoprotein blocks apoptosis induced by growth factor deprivation or irradiation, but the mechanism for this effect remains unclear. We therefore performed representational difference analysis (RDA) to identify downstream genetic targets of E2A-HLF, using a murine FL5.12 pro-B cell line that had been stably transfected with E2A-HLF cDNA under the control of a zinc-regulated metallothionein promoter. Two RDA clones, designated RDA1 and RDA3, were differentially upregulated in E2A-HLF-positive cells after zinc induction. The corresponding cDNAs encoded two WD40 repeat-containing proteins, Grg2 and Grg6. Both are related to the Drosophila protein Groucho, a transcriptional corepressor that lacks DNA-binding activity on its own but can act in concert with other proteins to regulate embryologic development of the fly. Expression of both Grg2 and Grg6 was upregulated 10- to 50-fold by E2A-HLF. Immunoblot analysis detected increased amounts of two additional Groucho-related proteins, Grg1 and Grg4, in cells expressing E2A-HLF. A mutant E2A-HLF protein with a disabled DNA-binding region also mediated pro-B cell survival and activated Groucho-related genes. Among the transcription factors known to interact with Groucho-related protein, only RUNX1 was appreciably downregulated by E2A-HLF. Our results identify a highly conserved family of transcriptional corepressors that are activated by E2A-HLF, and they suggest that downregulation of RUNX1 may contribute to E2A-HLF-mediated leukemogenesis.
PERFORMANCE COMPARISON AND ANALYSIS OF MOBILE AD HOC ROUTING PROTOCOLS

A mobile ad hoc network (MANET) is a wireless network that uses multi-hop peer-to-peer routing instead of static network infrastructure to provide network connectivity. MANETs have applications in rapidly deployed and dynamic military and civilian systems. The network topology in a MANET usually changes with time. Therefore, there are new challenges for routing protocols in MANETs since traditional routing protocols may not be suitable for MANETs. Researchers are designing new MANET routing protocols and comparing and improving existing MANET routing protocols before any routing protocols are standardized using simulations. However, the simulation results from different research groups are not consistent with each other. This is because of a lack of consistency in MANET routing protocol models and application environments, including networking and user traffic profiles. Therefore, the simulation scenarios are not equitable for all protocols and conclusions cannot be generalized. Furthermore, it is difficult for one to choose a proper routing protocol for a given MANET application. According to the aforementioned issues, this paper focuses on MANET routing protocols. Specifically, my contribution includes the characterization of different routing protocols and compare and analyze the performance of different routing protocols.
The Meta Distribution of the SINR in mm-Wave D2D Networks

In this paper, the meta distribution of the signal-to- interference-plus-noise ratio (SINR) in millimeter wave (mm-wave) device-to-device (D2D) networks is studied, which is the distribution of the conditional SINR distribution given a realization of the point process modeling the network. This analysis provides much more fine-grained information on the performance of individual links than just the mean that is usually evaluated. Modeling the D2D transmitters as a Poisson point process (PPP) and considering the unique mm-wave features, moments of the conditional SINR distribution given the point process are derived in order to calculate analytical expression for the meta distribution. It turns out that when the size of the antenna array tends to infinity, the noise is totally suppressed and the node density becomes the dominating factor affecting the interference in the network. Closed-form approximations of the meta distribution with the beta distribution are also provided. Numerical results give interesting insights into the effects of mm-wave features on the performance of D2D communication.
Cine‐MRI versus two‐dimensional echocardiography to measure in vivo left ventricular function in rat heart

Two‐dimensional echocardiography is the most commonly used non‐invasive method for measuring in vivo cardiac function in experimental animals. In humans, measurements of cardiac function made using cine‐MRI compare favourably with those made using echocardiography. However, no rigorous comparison has been made in small animals. Here, standard short‐axis two‐dimensional (2D) echocardiography (2D‐echo) and cine‐MRI measurements were made in the same rats, both control and after chronic myocardial infarction. Correlations between the two techniques were found for end diastolic area, stroke area and ejection fraction, but cine‐MRI measurements of ejection fraction were 12 ± 6% higher than those made using 2D‐echo, because of the 1.8‐fold higher temporal resolution of the MRI technique (4.6 ms vs 8.3 ms). Repeated measurements on the same group of rats over several days showed that the cine‐MRI technique was more reproducible than 2D‐echo, in that 2D‐echo would require five times more animals to find a statistically significant difference. In summary, caution should be exercised when comparing functional results acquired using short‐axis 2D‐echo vs cine‐MRI. The accuracy of cine‐MRI allows identification of alterations in heart function that may be missed when using 2D‐echo. Copyright © 2008 John Wiley & Sons, Ltd.
A cohesive law for carbon nanotube/polymer interfaces based on the van der Waals force

We have established the cohesive law for interfaces between a carbon nanotube (CNT) and polymer that are not well bonded and are characterized by the van der Waals force. The tensile cohesive strength and cohesive energy are given in terms of the area density of carbon nanotube and volume density of polymer, as well as the parameters in the van der Waals force. For a CNT in an infinite polymer, the shear cohesive stress vanishes, and the tensile cohesive stress depends only on the opening displacement. For a CNT in a finite polymer matrix, the tensile cohesive stress remains the same, but the shear cohesive stress depends on both opening and sliding displacements, i.e., the tension/shear coupling. The simple, analytical expressions of the cohesive law are useful to study the interaction between CNT and polymer, such as in CNT-reinforced composites. The effect of polymer surface roughness on the cohesive law is also studied. r 2006 Elsevier Ltd. All rights reserved.
Perioperative Epidural or Intravenous Ketamine Does Not Improve the Effectiveness of Thoracic Epidural Analgesia for Acute and Chronic Pain After Thoracotomy

Objectives:Persistent postsurgical pain (PPP) after thoracotomy effect 50% to 80%. Nerve damage and central sensitization involving NDMDAr activation may play an important role. This study evaluates the efficacy of adding intravenous (IV) or epidural ketamine to thoracic epidural analgesia (TEA) after thoracotomy. Materials and Methods:Double-blind randomized study on patients undergoing thoracotomy allocated to one of the following: group Kiv (IV racemic ketamine 0.5 mg/kg preincisional +0.25 mg/kg/h for 48 h), group Kep (epidural racemic ketamine 0.5 mg/kg preincisional +0.25 mg/kg/h for 48 h), or group S (saline). Postoperative analgesia was ensured by TEA with ropivacaine and fentanyl. Pain visual analog scales (VAS), Neuropathic Pain Symptom Inventory, Catastrophizing Scale, and Quantitative Sensory Testing, measuring both the peri-incisional and distant hyperalgesia area, were conducted preoperatively and postoperatively until 6 months. Plasma ketamine levels and stability of the analgesic solutions were analyzed. Results:A total of 104 patients were included. PPP incidence was 20% at 6 months. Pain scores on coughing were significantly lower in Kiv and Kep than in S at 24 and 72 hours, but there were no differences afterwards. There were no significant differences in pain at rest, Neuropathic Pain Symptom Inventory, and Catastrophizing Scale, or in the area of mechanical allodynia at any time. Adverse effects were mild. Plasma ketamine levels did not differ significantly between groups. Analgesic solutions were stable. Conclusions:Adding epidural or IV racemic ketamine to TEA after thoracotomy did not lead to any reduction in PPP or allodynia. Epidural administration produced similar plasma ketamine levels to the IV route.
Intraperitoneal Pulse Calcitriol in the Treatment of Secondary Hyperparathyroidism in Patients on Continuous Ambulatory Peritoneal Dialysis

Objective To determine whether it is practicable to use intraperitoneal calcitriol to treat continuous ambulatory peritoneal dialysis (CAPD) patients with secondary hyperparathyroidism and whether this form of therapy is effective and safe. Design A prospective, nonrandomized study. Setting Division of Nephrology, Tertiary Hospital. Method Eight patients from our CAPD population were recruited (5 F,3 M), aged 24 to 63 years (mean 38.9 ± 7.6 yr). They had been on CAPD for 8 to 84 months (mean 47.6 ± 24.6 months). All the patients had bone biopsy -proven secondary hyperparathyroidism with 2 patients showing mixed lesions. The CAPD system was changed to the twinbag system (Ultrabag, Baxter Healthcare, McGaw Park, IL, U.S.A.) in all 8 patients, who were taught to inject the calcitriol directly through the short transfer set and the Tenckhoff catheter into the peritoneal cavity, twice per week before bedtime. Calcium carbonate or calcium acetate was used as the main phosphate binder. Intact parathyroid hormone level (iPTH), serum ionized calcium (iCa), serum phosphate, and serum total alkaline phosphatase (alk. phos.) levels were measured at baseline and then every 4 weeks. The mean duration of follow-up was 10.5 months ± 1.9 months. Results There was a significant drop of iPTH level from the pretreatment level of 100.6 ± 35.8 pmoll L to a level of 63.8 ± 48.7 pmoll L at 24 weeks (p = 0.036). The lowest level of iPTH attained was 43.4 ± 27.0 pmol/L at 48 weeks. Serum total alk. phos. also dropped from 232.4 ± 83.3 lUlL pretreatment to 147.9 ± 52.0 lUlL at 24 weeks (p = 0.017). The decrease in alk. phos. level paralleled the decrease in iPTH level. The mean serum iCa level did not show any significant rise throughout the study period. The maximum dose of calcitriol used was 6.6 ± 1.5 μg/week and the average dose of calcitriol was 5.4 ± 1.2 μg/week. One patient did not respond satisfactorily and she subsequently had a parathyroidectomy. Two episodes of peritonitis occurred during the study period, giving a peritonitis rate of one episode per 42 patient-months. There was no significant change in the urea clearance tests or the peritoneal equilibration tests before and after the study. Conclusion Intraperitoneal calcitriol is practicable, effective, and safe in the treatment of secondary hyperparathyroidism in CAPD patients.
A coverage-based drop-policy in wireless sensor network with disruptive connections

Many applications in Wireless Sensor Networks (WSNs) consider remote and large scale monitoring. For those scenarios, the whole network is difficultly fully connected all the time. A possible vision is the union of WSNs and Disruptive Tolerant Network(DTNs) concepts, where mobile nodes make collect data in sparse networks and deliver them to a base station. This work presents a buffer management strategy, which is a basic principle in DTN networks. The proposed solution considers the global coverage to choose which messages are dropped, therefore, minimizing the impact on monitoring application. Such solutions are important for WSNs applications with limited resources. We show through simulation that the proposed Coverage-Based Drop-Policy in Wireless Sensor Network with Disruptive Connections (CBDP) improves the network coverage compared to traditional DTN drop policies like Drop Last Packet (DL) and Drop First Packet (DF).
Identification of lactoferrin‐binding proteins from Treponema pallidum subspecies pallidum and Treponema denticola

Lactoferrin‐binding or ‐associated proteins were identified in Treponema pallidum subspecies pallidum and Treponema denticola by affinity column chromatography using human lactoferrin and detergent‐solubilized, radiolabelled spirochaetes. Two discrete polypeptides of T. pallidum with masses of 45 and 40kDa and a broad band from 29‐34 kDa exhibited association with human apo‐ and partially ferrated lactoferrin. T. denticola produced two proteins that associated with a lactoferrin affinity matrix (50 and 35 kDa). T. pallidum and T. denticola did not associate with soluble, human transferrin in parallel experiments. Soluble human lactoferrin competed with all lactoferrin‐associated proteins from T. pallidum and T. denticola in competitive‐binding assays. However, the T. denticola proteins dissociated from a lacto‐ferrin‐affinity matrix in the presence of differing concentrations of unlabelled, soluble lactoferrin competitor. Treatment with phospholipase D altered migration of the diffuse 29‐34 kDa band of T. pallidum suggesting that the polypeptide was lipid‐modified. Each of the lactoferrin‐binding proteins from T. pallidum and T. denticola reacted with pooled rabbit syphilitic antisera. The lactoferrin‐binding proteins of T. pallidum reacted with human sera from patients at all stages of syphilis. In addition, a monoclonal antibody generated against the 45 kDa polypeptide of T. pallidum crossreacted with the 29–34 kDa protein.
Analysis of temporal compression characteristics using active phase conjugation in systems with multiple antenna elements

In this paper we give first account of a simple analysis tool for modeling temporal compression for automatic mitigation of multipath induced intersymbol interference through the use of active phase conjugation (APC) technique. The temporal compression characteristics of an APC system is analyzed using a simple discrete channel model, and numerical results are provided to justify the theoretical findings.
High-Efficiency Silicon Solar Cells With Boron Local Back Surface Fields Formed by Laser Chemical Processing

The successful implementation of industrially feasible local boron dopings as local back surface field (LBSF) for high-efficiency silicon solar cells processed with laser chemical processing (LCP) is demonstrated for the first time. The processed passivated-emitter rear locally diffused solar cells with LCP LBSFs show cell efficiencies of up to 20.9% with a cell efficiency benefit of up to 0.3-0.4%abs. in comparison to the reference passivated emitter and rear cells processed with a doping-free LCP opening. The results show the potential of LCP to create boron dopings in order to decrease the contact resistance and reduce the minority carrier recombination at the local metal contacts in order to improve the fill factor and the open-circuit voltage, respectively.
Responses of the bed bug, Cimex lectularius, to temperature extremes and dehydration: levels of tolerance, rapid cold hardening and expression of heat shock proteins

This study of the bed bug, Cimex lectularius, examines tolerance of adult females to extremes in temperature and loss of body water. Although the supercooling point (SCP) of the bed bugs was approximately −20°C, all were killed by a direct 1 h exposure to −16°C. Thus, this species cannot tolerate freezing and is killed at temperatures well above its SCP. Neither cold acclimation at 4°C for 2 weeks nor dehydration (15% loss of water content) enhanced cold tolerance. However, bed bugs have the capacity for rapid cold hardening, i.e. a 1‐h exposure to 0°C improved their subsequent tolerance of −14 and −16°C. In response to heat stress, fewer than 20% of the bugs survived a 1‐h exposure to 46°C, and nearly all were killed at 48°C. Dehydration, heat acclimation at 30°C for 2 weeks and rapid heat hardening at 37°C for 1 h all failed to improve heat tolerance. Expression of the mRNAs encoding two heat shock proteins (Hsps), Hsp70 and Hsp90, was elevated in response to heat stress, cold stress and during dehydration and rehydration. The response of Hsp90 was more pronounced than that of Hsp70 during dehydration and rehydration. Our results define the tolerance limits for bed bugs to these commonly encountered stresses of temperature and low humidity and indicate a role for Hsps in responding to these stresses.
fMRI of intrasubject variability in ADHD: anomalous premotor activity with prefrontal compensation.

OBJECTIVE Children with attention-deficit/hyperactivity disorder (ADHD) consistently display increased intrasubject variability (ISV) in response time across varying tasks, signifying inefficiency of response preparation compared to typically developing (TD) children. Children with ADHD also demonstrate impaired response inhibition; inhibitory deficits correlate with ISV, suggesting that similar brain circuits may underlie both processes. To better understand the neural mechanisms underlying increased ISV and inhibitory deficits in children with ADHD, functional magnetic resonance imaging was used to examine the neural correlates of ISV during Go/No-go task performance. METHOD Event-related functional magnetic resonance imaging was used to study 25 children with ADHD and 25 TD children ages 8 to 13 years performing a simplified Go/No-go task. Brain-behavior correlations were examined between functional magnetic resonance imaging activation and ISV within and between groups. RESULTS For TD children, increased rostral supplementary motor area (pre-supplementary motor area) activation during No-go events was associated with less ISV, whereas the reverse was true for children with ADHD for whom increased pre-supplementary motor area activation was associated with more ISV. In contrast, children with ADHD with less ISV showed greater prefrontal activation, whereas TD children with more prefrontal activation demonstrated more ISV. CONCLUSIONS These findings add to evidence that dysfunction of premotor systems may contribute to increased variability and impaired response inhibition in children with ADHD and that compensatory strategies eliciting increased cognitive control may improve function. However, recruitment of prefrontal resources as a compensatory mechanism for motor task performance may preclude the use of those prefrontal resources for higher order, more novel executive functions with which children with ADHD often struggle.
