Real-Time Robot Localization, Vision, and Speech Recognition on Nvidia Jetson TX1

Robotics systems are complex, often consisted of basic services including SLAM for localization and mapping, Convolution Neural Networks for scene understanding, and Speech Recognition for user interaction, etc. Meanwhile, robots are mobile and usually have tight energy constraints, integrating these services onto an embedded platform with around 10 W of power consumption is critical to the proliferation of mobile robots. In this paper, we present a case study on integrating real-time localization, vision, and speech recognition services on a mobile SoC, Nvidia Jetson TX1, within about 10 W of power envelope. In addition, we explore whether offloading some of the services to cloud platform can lead to further energy efficiency while meeting the real-time requirements
Effective actions for bosonic topological defects.

We consider a gauge field theory which admits {ital p}-dimensional topological defects, expanding the equations of motion in powers of the defect thickness. In this way we derive an effective action and effective equation of motion for the defect in terms of the coordinates of the {ital p}-dimensional world surface defined by the history of the core of the defect.
Analytical Formula to Estimate the Maximum Inrush Current

This letter presents an analytical formula to predict the peak inrush current for a nonlinear inductor in series with a resistor. The formula is developed using nonlinear circuit analysis and its accuracy is verified by comparing the calculated peak inrush current to those obtained through time-domain simulations. The formula is very useful to estimate the impact of damping resistors on the transformer inrush current.
Identification and Subcellular Localization of the Subunits of L-type Calcium Channels and Adenylyl Cyclase in Cardiac Myocytes*

The properties of cardiac L-type channels have been well characterized electrophysiologically, and many such studies have demonstrated that the channels are regulated by a cAMP-dependent pathway. However, the subunit composition of native cardiac L-type calcium channels has not been completely defined. Furthermore, a very important question exists regarding the status of the C-terminal domain of the pore-forming α1subunit, as this domain has the potential to be the target of protein kinases but may be truncated as a result of post-translational processing. In the present studies, the α1C and β2 subunits were identified by subunit-specific antibodies after partial purification from heart membranes, or immunoprecipitation from cardiac myocytes. Both the β2and the full-length α1C subunits were found to be expressed and co-localized in intact cardiac myocytes along T-tubule membranes. Using a quantitative antibody binding analysis, we demonstrated that the majority of the α1C subunits in intact cardiac myocytes appear to be full-length. In addition, we observed that adenylyl cyclase is localized in a pattern similar to the channel subunits in cardiac myocytes. Taken together, our results provide new insights into the structural basis for understanding the regulation of L-type calcium channels by a cAMP-mediated signaling pathway.
Investigation of interior axially magnetized permanent magnet tubular linear machine used for electromagnetic launcher

Due to high winding utilization ratio, high thrust density, zero transverse end effect, and zero unilateral magnetic force, tubular linear machine (TLM) is a very suitable candidate for electromagnetic launcher. In this paper, two kinds of interior axially magnetized permanent magnet TLMs with and without slots are compared and evaluated with finite element method (FEM) from the aspects of magnetic field, thrust characteristic, thrust density, cogging force, and so on. It is shown that the slotted TLM has higher electromagnetic performance and thrust density, which is an important merit for the electromagnetic launcher. Then the slotted TLM is investigated more deeply by FEM. The material selection and structure optimization are researched to improve the electromagnetic performance. The thrust characteristic is much improved after optimization.
RAYLEIGH QUOTIENT ITERATION AND SIMPLIFIED JACOBI-DAVIDSON WITH PRECONDITIONED ITERATIVE SOLVES FOR GENERALISED EIGENVALUE PROBLEMS

The computation of a right eigenvector and corresponding finite eigenvalue of a large sparse generalised eigenproblem Ax = λMx using preconditioned Rayleigh quotient iteration and the simplified JacobiDavidson method is considered. Both methods are inner-outer iterative methods and we consider GMRES and FOM as iterative algorithms for the (inexact) solution of the inner systems that arise. The performance of the methods is measured in terms of the number of inner iterations needed at each outer solve. For inexact Rayleigh quotient iteration we present a detailed analysis of both unpreconditioned and preconditioned GMRES and it is shown that the number of inner iterations increases as the outer iteration proceeds. We discuss a tuning strategy for the generalised eigenproblem, and show how a rank one change to the preconditioner produces significant savings in overall costs for the Rayleigh quotient iteration. Furthermore for a specially tuned preconditioner we prove an equivalence result between inexact Rayleigh quotient iteration and simplified Jacobi-Davidson method. The theory is illustrated by several examples, including the calculation of a complex eigenvalue arising from a stability analysis of the linearised Navier-Stokes equations.
Semantic Rule-Based Equipment Diagnostic

Motivation. Diagnostic systems play an important role in industry since they help to maximise equipment’s up-time and minimise its maintenance and operating costs [16]. In the energy sector companies like Siemens often rely on rule-based diagnostics to analyse power generating equipment by, e.g., testing newly deployed electricity generating gas turbines [11], or checking vibration instrumentation [13], performance degradation [14], and faults in operating turbines. For this purpose diagnostic engineers create and use complex diagnostic rule-sets to detect equipment abnormalities. An important class of rules that are commonly used in Siemens are signal processing rules (SPRs) that allow one (i) filter, aggregate, combine, and compare signals1 coming from sensors installed in equipment and (ii) send notification messages when a certain pattern in signals is detected. Authoring SPR based rule-sets is challenging. We now discuss this challenge in details and then present our solution to address them.
An Event Study Analysis of the Economic Impact of IT Operational Risk and its Subcategories

Organizations’ growing exposure to IT operational risk, or the risk of failures of operational IT systems, could translate into significant losses. Despite this, there are notable theoretical and empirical gaps in the literature on IT operational risk. We propose the “resource weaknesses” framework, which extends the resource-based theory of the firm, as a theoretical lens for investigating IT operational risk and its impacts. We also theorize about and empirically examine the impact differences of two categories of IT operational failures: ones resulting in the disclosure, misuse, or destruction of data assets, and ones resulting in the loss of availability or the mis-operation of functional IT assets responsible for the handling of data assets. Whereas the former, data-related failures have had some coverage in the literature, little is known about the latter, function-related failures. We apply an event study analysis with a well-balanced data set of IT operational failure events that occurred in U.S. financial service firms over a 25-year period. We find that function-related events have a substantially larger negative wealth effect than data-related events, and that firm characteristics such as firm size and growth potential greatly influence the degree of wealth effect. We conclude with important implications for practice and research.
Extended ICMP to Support Multi-Part Messages

This document redefines selected ICMP messages to support multi-part operation. A multi-part ICMP message carries all of the information that ICMP messages carried previously, as well as additional information that applications may require. Multi-part messages are supported by an ICMP extension structure. The extension structure is situated at the end of the ICMP message. It includes an extension header followed by one or more extension objects. Each extension object contains an object header and object payload. All object headers share a common format. This document further redefines the above mentioned ICMP messages by specifying a length attribute. All of the currently defined ICMP messages to which an extension structure can be appended include an "original datagram" field. The "original datagram" field contains the initial octets of the datagram that elicited the ICMP error message. Although the original datagram field is of variable length, the ICMP message does not include a field that specifies its length. Therefore, in order to facilitate message parsing, this document allocates eight previously reserved bits to reflect the length of the "original datagram" field. The proposed modifications change the requirements for ICMP compliance. The impact of these changes on compliant implementations is discussed, and new requirements for future implementations are presented. This memo updates RFC 792 and RFC 4443. [STANDARDS-TRACK]
Effects of contact location and voltage amplitude on speech and movement in bilateral subthalamic nucleus deep brain stimulation

Subthalamic nucleus deep brain stimulation (STN‐DBS) is particularly effective in improving limb symptoms in Parkinson's disease. However, speech shows a variable response. Contact site and amplitude of stimulation have been suggested as possible factors influencing speech. In this double blind study, we assessed 14 patients post bilateral STN‐DBS, without medication. Six conditions were studied in random order as follows: stimulation inside the STN at low voltage (2 V) and at high voltage (4 V); above the STN at 2 V and at 4 V, at usual clinical parameters, and off‐stimulation. The site of stimulation was defined on the postoperative stereotactic MRI data. Speech protocol consisted of the assessment of intelligibility of the dysarthric speech, maximum sustained phonation, and a 1‐minute monologue. Movement was assessed using the UPDRS‐III. Stimulation at 4 V significantly reduced the speech intelligibility (P = 0.004) independently from the site of stimulation. Stimulation at 4 V significantly improved the motor function. Stimulation inside the nucleus was significantly more effective than outside the nucleus (P = 0.0006). The significant improvement in movement coupled with significant deterioration in speech intelligibility when patients are stimulated inside the nucleus at high voltage indicates a critical role for electrical stimulation parameters in speech motor control. © 2008 Movement Disorder Society
Effects of cassava hay supplementation on antibacterial activity of the lactoperoxidase system in raw milk of dairy cows.

Sixteen multiparous cows in early-to-mid lactation (82.4±8.6 day in milk, DIM) were used in a completely randomized block design with repeated measurement to evaluate the effects of cassava hay (CH) supplementation on antibacterial activity of the lactoperoxidase system in raw milk. The cows were blocked into four groups based on DIM and previous milk yield. Each group was randomly fed dietary treatment twice daily for four months. Treatment diets were: T1) concentrate (control); T2) concentrate+1 kgCH/head/day; T3) concentrate+2 kgCH/head/day; and T4) concentrate+3 kgCH/head/ day. The concentrate for each treatment was formulated to provide together with CH, a daily intake of 1,830-1,940 gm protein. The cows received 25 kg/head/day of ruzi grass silage. After a 14-d adaptation period, daily milk yield was recorded and the raw milk of the cows was collected every month and analyzed for lactoperoxidase and thiocyanate concentration, standard plate, coliform, psychrotrophic and thermophilic counts. Milk yield and milk lactoperoxidase concentrations were not affected by treatments (P>0.05). Thiocyanate concentrations were higher (P<0.01) for T2, T3 and T4 than for T1. Standard plate, coliform, psychrotrophic and thermophilic counts were lower in T2, T3 and T4 compared to T1. The results showed that supplementation of cassava hay to dairy cows increased the efficiency of antibacterial activity of the lactoperoxidase system in raw milk.

Gun Focus Effect Revisited

This study attempts to clarify the relationship between message emotional tone and memory vividness, specifically gun focus effect. Based on findings in neuroimaging research, it is claimed here that positive and negative messages trigger different processing mechanisms in the brain and therefore later detail retrieval is dependent on the degree to which the same processing paths are activated. Overall, data support an assumption that visual recognition aids negative arousing content detail memory more than positive. In contrast, cued recall procedure is more helpful for recalling positive detail. For central detail the matching cues work together with the arousing content to boost memory specificity. Yet for peripheral detail, the matching cues help overcome the harmful effects of arousing content by reducing forgetting. Thus visual recognition minimizes gun focus effect for negative visual content and enhances it for positive. At the same time, a cued recall task minimizes gun focus effect for positive visual content and enhances it for negative.
Normal anatomy and pathology of the posterior capsular area of the knee: findings in cadaveric specimens and in patients.

955 he imaging anatomy of the medial and lateral supporting structures of the knee has been previously described [1–3]. Normal anatomy and pathology of structures making up the posteromedial and posterolateral corners of the knee have also been discussed [2]. However, to our knowledge no articles have directly addressed the posterior capsular area of the knee at the level of the popliteal fossa. This area is well depicted on sagittal MR images. Fibers from the posteromedial and posterolateral knee do contribute to the posterior capsule. From the medial side of the knee, a portion of the distal semimembranosus tendon extends along the posterior aspect of the knee. This portion is referred to as the oblique popliteal ligament [1]. From the lateral side of the knee, fibers from the arcuate ligament contribute to the posterior knee capsule [3]. Pathologic conditions commonly affect the posterior knee capsule or intercondylar area. Hence, a correct understanding of the normal imaging anatomy of the posterior capsular area is necessary for precise location of a lesion. Precise location of a lesion is important for the surgical approach and for the differential diagnosis.

Attenuation of Bunyavirus Replication by Rearrangement of Viral Coding and Noncoding Sequences

ABSTRACT Bunyamwera virus (BUN) is the prototype virus of the family Bunyaviridae. BUN has a tripartite negative-sense RNA genome comprising small (S), medium (M), and large (L) segments. Partially complementary untranslated regions (UTRs) flank the coding region of each segment. The terminal 11 nucleotides of these UTRs are conserved between the three segments, while the internal regions are unique. The UTRs direct replication and transcription of viral RNA and are sufficient to allow encapsidation of viral RNA into ribonucleoprotein complexes. To investigate the segment-specific functions of the UTRs, we have used reverse genetics to recover a recombinant virus (called BUN MLM) in which the L segment open reading frame (ORF) is flanked by the M segment UTRs. Compared to wild-type virus, BUN MLM virus shows growth attenuation in cultured mammalian cells and a slower disease progression in mice, produces small plaques, expresses reduced levels of L mRNA and L (RNA polymerase) protein, synthesizes less L genomic and antigenomic RNA, and has an increased particle-to-PFU ratio. Our data suggest that the packaging of BUN RNAs is not segment specific. In addition, the phenotype of BUN MLM virus supports the finding that BUN UTRs differ in their regulation of RNA synthesis but suggests that the interplay between each segment UTR and its cognate ORF may contribute to that regulation. Since BUN MLM virus is attenuated due to an essentially irreversible mutation, the rearrangement of UTRs is a feasible strategy for vaccine design for the more pathogenic members of the Bunyaviridae.
Applicability of Marshall’s Agglomeration Theory to Indus-trial Clustering in the Japanese Manufacturing Sector: An Exploratory Factor Analysis Approach

This study explores the results of a location survey of new Japanese manufacturing plants from 1997 to 2004 and reports an industrial cluster in Japan. More specifically, this study identifies an industrial cluster and specifies its advantages based on an exploratory factor analysis (EFA), which explores the spatial position of the cluster through spatial variation of factor scores. The major finding of this study is that there exists an industrial cluster factor containing most of the location advantages of a Marshallian industrial cluster, especially the secondary reason of the location choice. In addition, through the spatial analysis of the factor scores, this study identifies two prefectures—Nagano and Niigata—where Marshallian advantages are most effective in attracting plant locations.

The Edge-to-Edge Technique f For Barlow ' s Disease

The basic concept of this technique is that mitral regurgitation can be corrected simply by suturing together the edges of the mitral leaflets just at the site where regurgitation occurs. In particular the free edge of the diseased leaflet is anchored to the corresponding edge of the opposing leaflet exactly where the regurgitant jet is located. When the jet of regurgitation is in the central part of the mitral valve, the application of the "edge-to-edge" technique produces a double orifice valve configuration (Figure 1). On the other hand, when the mitral lesion is commissural, the plication of this area creates a single orifice mitral valve with a relatively smaller area. The first instance is usually called double orifice repair, and the second paracommissural repair.
Evaluating Optical Contact Bonds Using Thin-Film ZnO Transducers

The bond integrity between optically bonded fused quartz blocks has been evaluated using ultrasonic waves in the frequency range from 200 MHz to 800 MHz. The ultrasonic waves were produced by thin-film zinc oxide (ZnO) transducers. By excitation of the thin film ZnO transducers on glass blocks of two different thicknesses and optically bonding their free surfaces opposite the transducers, the properties of the bonded area can be evaluated using transmission and reflection loss measurements. The measurements were made using pulse excitation and detection, and spectrum analyzer measurements
Molecular phylogeny and phylogeography of genus Pseudois (Bovidae, Cetartiodactyla): New insights into the contrasting phylogeographic structure

Abstract Blue sheep, Pseudois nayaur, is endemic to the Tibetan Plateau and the surrounding mountains, which are the highest‐elevation areas in the world. Classical morphological taxonomy suggests that there are two subspecies in genus Pseudois (Bovidae, Artiodactyla), namely Pseudois nayaur nayaur and Pseudois nayaur szechuanensis. However, the validity and geographic characteristics of these subspecies have never been carefully discussed and analyzed. This may be partially because previous studies have mainly focused on the vague taxonomic status of Pseudois schaeferi (dwarf blue sheep). Thus, there is an urgent need to investigate the evolutionary relationship and taxonomy system of this genus. This study enriches a previous dataset by providing a large number of new samples, based on a total of 225 samples covering almost the entire distribution of blue sheep. Molecular data from cytochrome b and the mitochondrial control region sequences were used to reconstruct the phylogeny of this species. The phylogenetic inferences show that vicariance plays an important role in diversification within this genus. In terms of molecular dating results and biogeographic analyses, the striking biogeographic pattern coincides significantly with major geophysical events. Although the results raise doubt about the present recognized distribution range of blue sheep, they have corroborated the validity of the identified subspecies in genus Pseudois. Meanwhile, these results demonstrate that the two geographically distinct populations, the Helan Mountains and Pamir Plateau populations, have been significantly differentiated from the identified subspecies, a finding that challenges the conventional taxonomy of blue sheep.
Development of a flat-field grazing-incidence XUV spectrometer and its application in picosecond XUV spectroscopy.

A new type of grazing-incidence spectrometer with a flat focal field is developed, and XUV spectroscopy in the extreme ultraviolet region ranging from 15 to 200 A is carried out. Soft x-ray line spectra emitted from picosecond laser plasmas of aluminum and iron targets are measured and good resolutions are obtained in the XUV region. The spectral regions of detection are extended to shorter wavelengths (15 A) using a finer spaced grating. Computational studies on x-ray spectra are also performed taking into account the transient characteristics of picosecond laser-produced plasmas; the importance of the transient treatment is clearly shown. This type of soft x-ray spectrometer should be useful for time-resolved picosecond soft x-ray spectroscopy.
