STM: SpatioTemporal and Motion Encoding for Action Recognition (2019)

Spatiotemporal and motion features are two complementary and crucial information for video action recognition. Recent state-of-the-art methods adopt a 3D CNN stream to learn spatiotemporal features and another flow stream to learn motion features. In this work, we aim to efficiently encode these two features in a unified 2D framework. To this end, we first propose an STM block, which contains a Channel-wise SpatioTemporal Module (CSTM) to present the spatiotemporal features and a Channel-wise Motion Module (CMM) to efficiently encode motion features. We then replace original residual blocks in the ResNet architecture with STM blcoks to form a simple yet effective STM network by introducing very limited extra computation cost. Extensive experiments demonstrate that the proposed STM network outperforms the state-of-the-art methods on both temporal-related datasets (i.e., Something-Something v1 & v2 and Jester) and scene-related datasets (i.e., Kinetics-400, UCF-101, and HMDB-51) with the help of encoding spatiotemporal and motion features together.
Polypyrrole Composite Electrodes in an All‐Polymer Battery System (1996)

We have fabricated an all‐polymer battery utilizing the redox properties of electrically conducting polymers for the anode and cathode in conjunction with an ionic conducting polymer gel electrolyte. The anode and cathode consist of pyrrole electropolymerized onto a graphite fiber substrate resulting in a high‐surface‐area, composite electrode. A polymer gel electrolyte, based on polyacrylonitrile, was solution cast onto the electrodes to form an all‐polymer cell. This system exhibits a specific charge capacity of based on the electroactive mass of the cathode and discharging the system to 0.4 V. These cells show no loss of capacity when cycled to 100 cycles.
Information technology and the independent hotel – failing tomake the connection? (1995)

Reviews the current uses of IT in the independent sector of the hotel industry by means of a survey in south Wales in 1994. Reveals that only 50 per cent of this sector uses IT and that use is essentially clerical. There are some inherent demographic factors creating a barrier, and a potential market for suppliers of hardware and software in the independent sector which is, so far, not met. Concludes that education, training and advice in the application of IT for independent hotels is urgently needed to compete in the “information age”.
Streaming potential properties of westerly granite with applications (1989)

This paper reports on laboratory measurements of the streaming potential properties of common minerals and in particular of Westerly granite. Data are presented for these solids in contact with simple electrolytic solutions and in one case for temperature variation in the range 5°–70°C. For 1:1 electrolytes the ratio of the streaming potential coupling coefficient to fluid resistivity was approximately −4 mV/(atm Ωm) and for 2:1 electrolytes −2 mV/(atm Ωm). The effect of temperature was small (0.05 mV/°C temperature increase) and indicates that the zeta potential was independent of temperature. Preliminary experimental results using mixed electrolytic solutions (NaCl + CaCl 2 ) and two‐phase fluid flow are also described. Two‐phase flow can enhance streaming potentials by as much as a factor of 3 or 4. The laboratory data are used to interpret streaming potentials in geological problems, such as earthquake prediction, geothermal prospecting using the self‐potential method, and surface conductivity contribution to the electrical resistivity of rocks.
Effect of terrain on path loss in urban environments for wireless applications (1998)

Path loss prediction algorithms for advanced wireless communication system planning have long considered the effect of electromagnetic propagation over buildings between the base station and subscriber. This phenomena is particularly important in residential areas, where the houses are typically a few stories high. For the most part, the buildings were assumed to lie on level terrain, although shadowing effects by the terrain in the absence of buildings has been included. Previous works have offered a number of methods to quantitatively determine these effects from path profiles. This study examines propagation over buildings when the buildings are located on terrain features (hills). The buildings, which are represented by a series of absorbing half screens, are assumed to lie in rows that are equally spaced along parallel streets, with the streets running perpendicular to the terrain slope. Numerical results are obtained using successive repetition of the Kirchhoff-Huygens approximation. A phenomenological model based on ray optics for diffraction over a smooth surface is proposed as a way to interpret the numerical results. The dependence of the model coefficients on the terrain parameters are obtained from the numerical results.
Role of 20-HETE in Elevating Chloride Transport in the Thick Ascending Limb of Dahl SS/Jr Rats (1999)

This study examined the role of endogenous 20 hydroxyeicosatetraenoic acid (20-HETE) in elevating Cl- transport in the medullary thick ascending loop of Henle (MTAL) of 9-week-old male Dahl salt-sensitive (SS/Jr) and salt-resistant (SR/Jr) rats perfused in vitro. Basal transepithelial voltage (Vte; 14.9+/-0.9 versus 10.1+/-0.5 mV) and net lumen-to-bath Cl- flux (JCl) (155+/-6 versus 127+/-5 pEq. min-1. mm-1) were significantly greater in MTAL isolated from SS/Jr rats (n=16) than in those obtained from SR/Jr rats (n=16). Blockade of the synthesis of 20-HETE with 17-octadecynoic acid (17-ODYA; 10 micromol/L) increased Vte from 9. 9+/-0.8 to 13.1+/-1.0 mV and JCl from 127+/-7 to 152+/-8 pEq. min-1. mm-1 in the MTAL of SR/Jr rats (n=8), but it had no significant effect on Vte or JCl in the MTAL of SS/Jr rats (n=8). Exogenous 20-HETE (1 micromol/L) decreased Vte from 14.8+/-0.6 to 10.5+/-0.6 mV and JCl from 155+/-10 to 116+/-6 pEq. min-1. mm-1 in MTAL of SS/Jr rats (n=8), but it had no effect on Vte or JCl in the MTAL of SR/Jr rats (n=8). The expression of P4504A2 protein in the MTAL of SS/Jr rats was approximately half of that seen in the MTAL of SR/Jr rats. These results indicate that endogenously formed 20-HETE regulates transepithelial voltage and Cl- transport in the MTAL and that a diminished production of 20-HETE contributes to an elevation in Cl- transport in the MTAL of SS/Jr rats.
A Promising DNA Methylation Signature for the Triage of High-Risk Human Papillomavirus DNA-Positive Women (2014)

High-risk human papillomavirus (hrHPV)-DNA testing is frequently performed parallel to cytology for the detection of high-grade dysplasia and cervical cancer particularly in women above 30 years of age. Although highly sensitive, hrHPV testing cannot distinguish between HPV-positive women with or without clinically relevant lesions. However, in principle discrimination is possible on the basis of DNA methylation markers. In order to identify novel DNA regions which allow an effective triage of hrHPV-positive cases, hypermethylated DNA enriched from cervical cancers was compared with that from cervical scrapes of HPV16-positive cases with no evidence for disease by CpG island microarray hybridization. The most promising marker regions were validated by quantitative methylation-specific PCR (qMSP) using DNA from archived cervical tissues and cervical scrapes. The performance of these markers was then determined in an independent set of 217 hrHPV-positive cervical scrapes from outpatients with histopathological verification. A methylation signature comprising the 5' regions of the genes DLX1, ITGA4, RXFP3, SOX17 and ZNF671 specific for CIN3 and cervical cancer (termed CIN3+) was identified and validated. A high detection rate of CIN3+ was obtained if at least 2 of the 5 markers were methylated. In the subsequent cross-sectional study all cervical carcinomas (n = 19) and 56% (13/23) of CIN3 were identified by this algorithm. Only 10% (11/105) of hrHPV-positive women without histological evidence of cervical disease were scored positive by the methylation assay. Of note is that the detection rate of CIN3 differed between age groups. Eight of nine CIN3 were detected among women ≥30 years of age but only five of fourteen among <30 year old group (p = 0.03). The specificity for CIN3+ in the older age group was 76.6% (95% CI 65.6-85.5%). Clinical validation studies are required to determine the usefulness of these novel markers for triage after primary hrHPV testing in a cervical cancer screening setting.

Novel Trisaccharide Fatty Acid Ester Identified from the Fruits of <i>Morinda citrifolia</i> (Noni) (1999)

Two known glycosides and a novel trisaccharide fatty acid ester were isolated from the n-butanol-soluble fraction of the fruits of Morinda citrifolia (noni). Structure determination was carried out by spectral techniques such as MS, IR, NMR, and 2D-NMR. The novel trisaccharide fatty acid ester was elucidated as 2, 6-di-O-(beta-D-glucopyranosyl)-1-O-octanoyl-beta-D-glucopyranose. The known compounds were identified as rutin and asperulosidic acid.
Roles of growth factors in the development of bovine embryos fertilized in vitro and cultured singly in a defined medium (1996)

Bovine embryos at the 8- or 16-cell stage were cultured singly, or in groups (10-12 embryos), in the presence or absence of bovine oviduct epithelial cells (BOEC) in a defined medium which was used as a basic culture medium. A higher (P < 0.05) proportion of 8-cell embryos (48.3-50.8%) cultured singly developed beyond the 8-cell stage after the addition of platelet-derived growth factor (PDGF)-AB (1 ng mL-1) only, or with PDGF-AB + basic fibroblast growth factor (bFGF; 1 ng ml-1) + transforming growth factor (TGF)-beta 1 beta 2 (1 ng mL-1) than in basic medium alone (30.3%). In contrast, a significantly (P < 0.02) higher percentage (62.6-65.8%) of 16-cell embryos developed to the morula stage after the addition of TGF-beta 1 beta 2 only, or the addition of TGF-beta 1 beta 2 + bFGF + PDGF-AB than in basic medium alone (30.2%). These proportions were not significantly (P > 0.05) different from the proportions obtained when embryos were cultured in groups, but were significantly (P < 0.005) lower than the proportions obtained when embryos were cultured in groups on BOEC monolayers. Arachidonic acid (50 ng mL-1), beta-mercaptoethanol (10 microM) and glutathione (10-1000 microM) stimulated the development of 8-cell embryos in the presence of PDGF and TGF-beta 1 beta 2; blastocyst formation was observed for the first time in 8-cell embryos cultured singly in the presence of these embryotrophic substances (2.2-6.2%).

Infectious bronchitis virus variants: a review of the history, current situation and control measures (2011)

The history, current situation and control measures for infectious bronchitis virus (IBV) variants are reviewed. A large number of IBV variants exist worldwide; some being unique to a particular area, others having a more general distribution. The possible reasons why some strains spread readily over major parts of the world, whereas other strains stay more localized are discussed. The advantages and disadvantages of strain classification by protectotyping, serotyping and genotyping are discussed in relation to in vivo protection. The different vaccination strategies are also considered.
Bioavailability of zinc glycinate in comparison with zinc sulphate in the presence of dietary phytate in an animal model with <sup>65</sup>Zn labelled rats (2005)

The objective of this study was to quantify the bioavailability of zinc (Zn) from sulphate and glycinate as representatives of inorganic and organic zinc sources. The semi-synthetic basal diet contained 2 microg/g of native Zn and was fortified with pure sodium-phytate (8 g/kg) in order to simulate conditions of common cereal-based meals. The basal diet was supplemented with either 53 microg/g of Zn from sulphate (control) or 10 microg/g of Zn from either sulphate (ZnSulphate) or glycinate (ZnGly). Twenty-four (65)Zn-labelled, growing rats weighing 133 g were allotted to the three diets (eight animals per treatment) and were kept pair-fed to ZnSulphate for 15 days. Zn contents in blood plasma, femur and whole body, as well as, plasma alkaline phosphatase activities were reduced compared with control indicating a zinc deficiency in ZnSulphate and ZnGly treatment. This allowed their differentiation in zinc bioavailability. True absorption of dietary Zn was significantly higher in ZnGly than in ZnSulphate (51% vs. 44%) while losses of endogenous faecal Zn and urinary Zn were not affected to a quantitatively relevant extent (mean: 17% and 2% of intake). This resulted in a +30% significantly improved Zn retention for ZnGly (33% vs. 25%) and a lower severity on Zn deficiency symptoms compared with ZnSulphate. Metabolic utilization accounted for 95% of absorbed dietary Zn for both Zn sources. Overall, the bioavailability of zinc glycinate was significantly superior by 16% to zinc sulphate (49% vs. 42%), mainly because of a higher absorptive potential at presence of a strong anti-nutritive component (phytate) in the diet.
An assessment of ultra-capacitors as the power cache in Toyota THS-II, GM-Allision AHS-2 and Ford FHS hybrid propulsion systems (2005)

In this paper a brief history of the development paths leading to power split concepts is given. The power split architecture is used as the comparison platform because the global OEM's have converged to the electronic CVT in two different configurations, Toyota and Ford to the single epicyclic gear set, THS and FHS respectively and GM-Allison to the dual epicyclic gear set, AHS designs, each requiring a pair of electric motor-generators in order to deliver their intended function. The power electronic architecture for the Toyota Hybrid System, THS can be in either a battery unbuffered THS-I or battery buffered via a buck/boost converter as in THS-II. The GM-Allison Advanced Hybrid System, AHS is configured as a battery unbuffered configuration, but it could also be realized using the battery buffered configuration. Benefits of ultra-capacitor augmentation of the energy storage system in both unbuffered and buffered configurations are investigated
Generation of acoustic waves by an impulsive line source in a fluid/solid configuration with a plane boundary (1983)

The space–time acoustic wave motion generated by a two-dimensional, impulsive, monopole line source in a fluid/solid configuration with a plane boundary is calculated with the aid of the modified Cagniard technique. The source is located in the fluid, and numerical results are presented for the reflected-wave acoustic pressure, especially in those regions of space where head wave contributions occur. There is a marked difference in time response in the different regimes that exist for the wave speed in the fluid in relation to the different wave speeds (compressional, shear, Rayleigh) in the solid. These differences are of importance to the situation where the reflected wave in the fluid is used to determine experimentally the elastic properties of the solid.
Self-phasing array antennas (1964)

A self-phasing array antenna is described which operates on the incident wavefront in such a manner that when it is retransmitted it returns whence it came as a coherent wavefront irrespective of the original phase distribution incident on the array. Self-phasing is useful where a two-way propagation path is available and where a conventional antenna cannot operate efficiently because of an unknown phase distribution in the incident wavefront. The operation of a self-phasing array, its properties, its relation to other antenna design techniques and its potential applications are discussed.
Combination of Foot Stimulation and Tramadol Treatment Reverses Irritation Induced Bladder Overactivity in Cats (2012)

This study suggests a new treatment strategy for overactive bladder by combining foot stimulation with a low dose of tramadol, which is noninvasive and has potentially high efficacy and fewer adverse effects.
Secure Publishing using Schema-level Role-based Access Control Policies for Fragments of XML Documents (2009)

Popularity of social networks is growing rapidly and secure publishing is an important implementation tool for these networks. At the same time, recent implementations of access control policies (ACPs) for sharing fragments of XML documents have moved from distributing to users numerous sanitized sub-documents to disseminating a single document multi-encrypted with multiple cryptographic keys, in such a way that the stated ACPs are enforced. Any application that uses this implementation of ACPs will incur a high cost of generating keys separately for each document. However, most such applications, such as secure publishing, use similar documents, i.e. documents based on a selected schema. This paper describes RBAC defined at the schema level, (SRBAC), and generation of the minimum number of keys at the schema level. The main advantage of our approach is that for any application that uses a fixed number of schemas, keys can be generated (or even pre-generated) only once, and then reused in all documents valid for the given schema. While in general, key generation at the schema level has to be pessimistic, our approach tries to minimize the number of generated keys. Incoming XML documents are efficiently encrypted using single-pass SAX parsing in such a way that the original structure of these documents is completely hidden. We also describe distributing to each user only keys needed for decrypting accessible nodes, and for applying the minimal number of encryption operations to an XML document required to satisfy the protection requirements of the policy.
Low-loss NiZnCo ferrite processed at low sintering temperature with matching permeability and permittivity for miniaturization of VHF-UHF antennas (2017)

Spinel ferrites of a nominal composition of Ni0.5Zn0.3Co0.2Fe2O4 (NiZnCo) with various B2O3–Bi2O3–SiO2–ZnO (BBSZ) glass additions were successfully synthesized at a relatively low temperature of 930 °C for their potential applications as magneto-dielectric antenna substrate materials. Measurements of magnetic and dielectric properties show that, with an increasing content of BBSZ from 0 to 2 wt. %, the permeability μ′ at low frequencies was increased from ∼4.7 to ∼8.9, whereas the permittivity ε′ was improved from ∼5.9 to ∼12.5. These tunable permeability and permittivity were proved to be closely related to the grain size and density, based on the magnetic circuit model and effective medium theory. Importantly, the sample with 0.5 wt. % addition demonstrated the optimal magneto-dielectric performance with nearly equivalent values of μ′ and ε′, which yields a large miniaturization factor of ∼6.5 and the normalized impedance of ∼1 over the frequency range of 10 MHz–1 GHz. Moreover, this sample exhibits low loss characteristics over a wide frequency range, where the dielectric loss tan δε is in the order of 10−3 and the magnetic loss tan δμ is less than 0.15. These properties make the ferrite material a promising candidate for miniaturized antennas with good impedance matched to free space and open a great potential for low-temperature co-fired ceramic applications toward the practical fabrication and high integration of the antennas.

Multisource Software on Multicore Automotive ECUs—Combining Runnable Sequencing With Task Scheduling (2012)

As the demand for computing power is quickly increasing in the automotive domain, car manufacturers and tier-one suppliers are gradually introducing multicore electronic control units (ECUs) in their electronic architectures. In addition, these multicore ECUs offer new features such as higher levels of parallelism, which ease the compliance with safety requirements such as the International Organization for Standardization (ISO) 26262 and the implementation of other automotive use cases. These new features involve greater complexity in the design, development, and verification of the software applications. Hence, car manufacturers and suppliers will require new tools and methodologies for deployment and validation. In this paper, we address the problem of sequencing numerous elementary software modules, called runnables, on a limited set of identical cores. We show how this problem can be addressed as the following two subproblems, which cannot optimally be solved due to their algorithmic complexity: 1) partitioning the set of runnables and 2) building the sequencing of the runnables on each core. We then present low-complexity heuristics to partition and build sequencer tasks that execute the runnable set on each core. Finally, we globally address the scheduling problem, at the ECU level, by discussing how we can extend this approach in cases where other OS tasks are scheduled on the same cores as the sequencer tasks.
