An Efficient Umpire Key Frame Segmentation in Cricket Video using HOG and SVM (2021)

The identification of most important frames in games videos is a universal issue for several purposes, such as games categorization, recognition of acts, Human identification, object classification and video summarization. These tasks can be carried out greater efficaciously as an alternative to maintaining the entire recording, only a handful of main frames are used. In an immense corpus of preparing information to show the models, existing key casing discovery strategies is commonly anticipated managed examination and include manual stamping of keyframes. Naming requires human marginalize from various foundations to clarify key casings in recordings which aren't just costly and tedious yet additionally inclined to emotional blunders and irregularities between the labelers. To beat these problems, we propose a programmed self-managed strategy for distinguishing key casings in a video. To beat these issues, we suggest programmed and self-directed division and examination of Umpire keyframe of side interest in cricket video photographs by means of filtering Blur, Sky oriented, Replay, and Crowded frames which are now not useful frames for the Umpire Action Recognition in Highlight Extraction. Our method comprises an algorithm which segments umpire Key Frames by filtering Blur, Crowded, Replay and Sky view oriented frames for the manually selected ODI Cricket Video of Length 2:12:38 seconds. The projected scheme works in two parts.

Autonomous underground navigation of an LHD using a combined ICP-EKF approach (2002)

A new approach for the autonomous navigation of a load-haul-dump (LHD) truck in an underground mine is presented. The development of a minimal-structure combined ICP-EKF algorithm utilizing a scanning-laser range-finder for the localization of the vehicle is described. The iterative closest point (ICP) algorithm is employed for matching the scanned data to an existing map in the form of a poly-line. This combined approach efficiently deals with the uncertainty present in the range data. An extended Kalman filter (EKF) algorithm is employed, that exploits a nonlinear kinematic model incorporating the vehicle-slip, a nonlinear observation model based on the vertices of the poly-line map, and the bearing of the laser-observations. This provides reliable vehicle estimates. Real data gathered during a trial run in the mine is employed in testing the efficiency of this approach which is found to be robust with respect to occlusions and outliers, demonstrating the successful navigation of the LHD.
Dynamic Channels: a New Development Methodology for Mobile Computing Applications (1998)

We discuss the software engineering of mobile computing information dissemination systems and introduce dynamic channels, a set of extensions to the conceptual models developed for information channels, capturing mobility-specific requirements. These are used for filtering and setting update order priorities for the information that users intend to monitor, which depends on their location and changes as they roam. We also present a new development methodology for a class of mobile computing applications operating under an information dissemination metaphor. The methodology is based on UML, the OMG standard for objectoriented analysis and design. Keywords: Mobile computing applications, Information-push, Object-oriented development. 1. Introduction Mobile computing environments bring new challenges to software developers. Presently, most applications are built following a user-in-control model, where user commands trigger clientserver exchanges of information. However, the mob...
Augmentation of host resistance to Listeria monocytogenes infection by Lactobacillus casei. (1985)

The effect of heat-killed Lactobacillus casei YIT 9018 (LC 9018), a potent antitumor agent as well as a potent macrophage-activating agent, on the resistance of mice to Listeria monocytogenes was studied. Mice pretreated intravenously (i.v.) with 0.5 mg of LC 9018 showed enhanced resistance to subsequent i.v. infection with L. monocytogenes. Antigenic cross-reaction between L. monocytogenes and LC 9018 was not seen in the delayed footpad reaction in mice, and LC 9018 inhibited the growth of L. monocytogenes in the liver and spleen of athymic nude mice. Therefore the antilisterial activity of LC 9018 was considered to be expressed nonspecifically and independently of the thymus. Carrageenan, a selective macrophage blocker, diminished the antilisterial effect of LC 9018. Peritoneal cells induced by intraperitoneal administration of LC 9018, which were composed mainly of macrophages and polymorphonuclear cells, showed enhanced phagocytosis and marked intracellular killing activity against L. monocytogenes in vitro as compared with those of the control. Kupffer cells of mice pretreated i.v. with LC 9018 produced a high oxygen radical level. The antilisterial effect of LC 9018 was maintained even at 21 days after its injection.
Surface composition and etching of III-V semiconductors in Cl2 ion beams (1982)

Surface composition and etching of InP and GaAs in Cl2 ion beams was investigated. In situ analysis of the substrate using Auger electron spectroscopy demonstrated selective removal of phosphorous from InP leaving a thin (⩽50 Å) surface layer enriched with In after etching at room temperature with a 500-eV Cl+/Cl+2 beam. GaAs does not show selective removal of the group V element, resulting in no significant change in surface composition after etching. These results reflect the involatility of the In chlorides at room temperature. Etch rate results indicate that at low ion energy (200 eV) or high neutral reactant flux, removal of the group III chloride from the surface is rate limiting. At high ion energy (500 eV) and low neutral flux, supply of reactant to the surface is rate limiting.
Effect of Strain Rates on Strength of Sheet Steels (1997)

Stain rate sensitivity of deformation behavior in various sheet steels were investigated in order to find out the suitable steel for automotive anti-crash parts. Dual phase steels consisted of ferrite and martensite phases absorbed higher energy at strain rate of 2 × 103/s with lower yield strength at strain rate of 2 × 10-2/s, compared with other steels. Higher energy absorption of dual phase steels was due to high strain rate sensitivity of yield strength and n-value. Increase of volume fraction or large surface area of martensite phase in dual phase steel led higher strain rate sensitivity in work hardenability as well as yield strength.
Second Harmonic Generation from AlAs/GaAs Vertical Cavity (1994)

Second harmonic generation(SHG) in semiconductors such as GaAs and AlGaAs has been demonstrated to realize compact short wavelength light sources.1·2·3·4·5·6·7 Most of the devices are surface emitters, which radiate SH wave normal to the surface with horizontally propagating fundamental waves.2·3’4·6·7 A stack of GaAs and AlGaAs with a period of half a wavelength of the second harmonic has been incorporated to give quasi phase matched(QPM) SHG.5·6·7
Design and proof-of-concept for targeted phage-based COVID-19 vaccination strategies with a streamlined cold-free supply chain (2021)

The ongoing COVID-19 global pandemic has accounted for over 2.5 million deaths and an unprecedented impact on the health of mankind worldwide. Over the past several months, while a few COVID-19 vaccines have received Emergency Use Authorization and are currently being administered to the entire human population, the demand for prompt global immunization has created enormous logistical challenges--including but not limited to supply, access, and distribution--that justify and reinforce the research for additional strategic alternatives. Phage are viruses that only infect bacteria and have been safely administered to humans as antibiotics for decades. As experimental proof-of-concept, we demonstrated that aerosol pulmonary vaccination with lung-targeted phage particles that display short epitopes of the S protein on the capsid as well as preclinical vaccination with targeted AAVP particles carrying the S protein gene elicit a systemic and specific immune response against SARS-CoV-2 in immunocompetent mice. Given that targeted phage- and AAVP-based viral particles are sturdy yet simple to genetically engineer, cost-effective for rapid large-scale production in clinical grade, and relatively stable at room temperature, such unique attributes might perhaps become additional tools towards COVID-19 vaccine design and development for immediate and future unmet needs.
Mood stabilizers for patients with bipolar disorder: the state of the art (2010)

Bipolar disorder (BD) is a prevalent and disabling condition, often comorbid with other medical and psychiatric conditions and frequently misdiagnosed. International treatment guidelines for BD recommend the use of mood stabilizers – either in monotherapy or in association – as the gold standard in both acute and long-term therapy. Commonly used in the clinical practice of BD, mood stabilizers have represented an evolving field over the last few years. The concept of stabilization, in fact, has been stressed as the ultimate objective of the treatment of BD, given the chronic and recurrent nature of the illness, which accounts for its significant levels of impairment and disability. To date, different compounds are included within the broad class of mood stabilizers, with lithium, anticonvulsants and, more recently, atypical antipsychotics being the most representative agents. This article is aimed at providing an updated review of the available literature in relation to the role of mood stabilizers in BD, with particular emphasis on their mechanism of action, main clinical aspects and specific use in the different phases of BD treatment, according to the most recently published international treatment guidelines.
New wideband integrated miniature branchline coupler for beamforming applications (2012)

In this paper, we present a new wideband miniature branchline coupler as a key element to be integrated for 60 GHz beamforming networks in phased arrays. Theory and equations as well as a first proof-of-concept at 2.2 GHz are presented. A 25% matching bandwidth (−10 dB), ± 1 dB amplitude imbalance and ± 2° phase imbalance are measured with a reduced footprint. Then, the same coupler topology is optimized at 60 GHz in a BiCMOS9MW and IPD technology, both from ST Microelectronics. Its implementation on both technologies is discussed and compared to state-of-the art recently published couplers operating at 60 GHz.
Two-Layer Energy-Management Architecture for a Fuel Cell HEV Using Road Trip Information (2012)

This paper investigates the design of a two-layer energy-management system for a fuel cell hybrid electric vehicle (HEV). The first layer (upper layer) deals with the vehicle energy consumption, whereas the second layer (lower layer) deals with the power splitting between the fuel cell and the battery. The upper layer aims at providing the globally optimal energy consumption profile by considering the road-trip information and the vehicle dynamics. This energy profile is independent of the number and type of power sources on the vehicle. Therefore, it can be used to assist the real-time power splitting algorithm implemented into the lower layer. This layer design goal is mainly to share the vehicle power demand between the fuel cell and the battery while minimizing the hydrogen consumption. In addition, the splitting method takes into account the fuel cell efficiency map and the hydrogen/electricity relative pricing while imposing a smooth behavior on the fuel cell. This smooth behavior is desirable to preserve the fuel cell life and reduce the oxygen starvation phenomenon. The proposed energy-management system has been successfully implemented and validated on an HEV test bench. The experiments and simulations using several standard driving cycles suggest that the approach can reduce the hydrogen consumption up to 10% compared to a rule-based method and a depleting-sustaining method while preserving at the same time the battery pack from overdischarging.
Development and Distribution of Root System in Two GrainSorghum Cultivars Originated from Sudan under Drought Stress (2005)

The difference in rooting pattern between two grain sorghum cultivars differing in drought tolerance was investigated under drought stress. The cultivars, Gadambalia (drought-tolerant) and Tabat (droughtsusceptible), were grown in bottomless wooden or acrylic root boxes to examine root parameters. Gadambalia consistently exhibited higher dry matter production and leaf water potential than Tabat under drought stress in both root boxes. In the experiment with wooden root boxes, under a drought condition, Gadambalia extracted more water from deep soil layers (1.1-1.5 m), which was estimated from the reduction in soil water content, than Tabat. This was because Gadambalia had a significantly higher root length density in these soil layers. The high root length density was due to enhanced lateral root development in Gadambalia. In the other experiment with acrylic root boxes, though total root length in the upper soil layer (0-0.5 m) was declined by limited irrigation in both cultivars, the reduction in Gadambalia was moderate compared with that in Tabat owing to the maintenance of fine root growth. Unlike Tabat, Gadambalia had an ability to produce the nodal roots from higher internodes even under drought, which resulted in the high nodal root length of Gadambalia. The growth angle of nodal roots was significantly correlated with root diameter, and the nodal roots from the higher internodes had large diameters and penetrated into the soil more vertically. These results indicate that the responses of roots (i.e. branching and/or growth of lateral root, and nodal root emergence from higher internodes) to soil dryness could be associated with the drought tolerance of Gadambalia.
Continuous RAFT miniemulsion polymerization of styrene in a train of CSTRs (2005)

Abstract Reversible addition fragmentation transfer (RAFT) miniemulsion polymerization of styrene in a train of continuous stirred tank reactors (CSTRs) is described. It is observed that the polydispersity of the polymer decreases as the number of CSTRs in the train increases, as has been derived theoretically. Furthermore, the CSTRs do not reach steady state, which has been attributed to, at least in part, slow oligomerization of monomer and capping by RAFT agent in the feed. Particle nucleation in a CSTR is found to be less effective than in a batch reactor. This is attributed to a “dry‐out” mechanism, which is observed to be more significant in a CSTR than in batch, leading to a “nongrowing” population of dormant chains. Experimental evidence for the presence of this “nongrowing” population is also provided. © 2005 American Institute of Chemical Engineers AIChE J, 51: 1009–1021, 2005
Three-Dimensional Structure and Dynamics of Wine Tannin−Saliva Protein Complexes. A Multitechnique Approach (2003)

The interactions between the B3 (catechin-4alpha,8-catechin) red wine tannin and the human salivary protein fragment IB7(14) (SPPGKPQGPPPQGG) were monitored by (1)H magic angle spinning NMR, circular dichroism, electrospray ionization mass spectrometry, and molecular modeling. It is found that the secondary structure of IB7(14) is made of a type II helix (collagen helix) and random coil. The central glycine 8 appears to act as a flexible rotula separating two helix II regions. Three tannin molecules tightly complex the peptide, without modifying its secondary structure, but seem to reduce its conformational dynamics. The binding dissociation constant is in the millimolar range. B3 tannins with a "tweezers" conformation bind to the hydrophilic side of the saliva peptide, suggesting that the principal driving forces toward association are governed by hydrogen bonding between the carbonyl functions of proline residues and both the phenol and catechol OH groups. These findings are further discussed in the frame of an astringency phenomenon.
Noradrenaline-Functionalized Hyperbranched Fluoropolymer–Poly(ethylene glycol) Cross-Linked Networks As Dual-Mode, Anti-Biofouling Coatings (2012)

The strategy of decorating antibiofouling hyperbranched fluoropolymer-poly(ethylene glycol) (HBFP-PEG) networks with a settlement sensory deterrent, noradrenaline (NA), and the results of biofouling assays are presented. This example of a dual-mode surface, which combines both passive and active modes of antibiofouling, works in synergy to improve the overall antibiofouling efficiency against barnacle cyprids. The HBFP-PEG polymer surface, prior to modification with NA, was analyzed by atomic force microscopy, and a significant distribution of topographical features was observed, with a nanoscopic roughness measurement of 110 ± 8 nm. NA attachment to the surface was probed by secondary ion mass spectrometry to quantify the extent of polymer chain-end substitution with NA, where a 3- to 4-fold increase in intensity for a fragment ion associated with NA was observed and 39% of the available sites for attachment were substituted. Cytoskeletal assays confirmed the activity of tethered NA on adhering oyster hemocytes. Settlement assays showed deterrence toward barnacle cyprid settlement, while not compromising the passive biofouling resistance of the surface. This robust strategy demonstrates a methodology for the incorporation of actively antibiofouling moieties onto a passively antibiofouling network.
Robot-aided sensorimotor arm training improves outcome in patients with chronic stroke (2003)

Thirty patients with chronic stroke received 6 weeks of sensorimotor robotic training in a pilot study that targeted motor function of the affected shoulder and elbow. The impairment and disability scores were stable during a 2-month observation/measurement period, improved significantly by program completion, and remained robust in the 3-month follow-up. Task-specific motor training attenuated a chronic neurologic deficit well beyond the expected period for improvement after stroke.
<i>Arabidopsis thaliana</i> subcellular responses to compatible <i>Erysiphe cichoracearum</i> infections (2005)

Subcellular events of Erysiphe cichoracearum infections of epidermal cells were visualized in living tissues of Arabidopsis plants carrying various green fluorescent protein (GFP)-tagged organelles via laser scanning confocal microscopy. Early in the infection sequence, cytoplasm and organelles moved towards penetration sites and accumulated near penetration pegs. Peroxisomes appeared to accumulate preferentially relative to the cytoplasm at penetration sites. Another early event, which preceded haustorium formation, was the aggregation of some GFP-tagged plasma membrane marker proteins into rings around penetration sites, which extended across cell-wall boundaries into neighboring cells. This feature localized to sites where papillae were deposited. The extrahaustorial membrane (EHM) encases the fungal feeding structure, the haustorium, separating it from the host cytoplasm. Eight plasma membrane markers were excluded from the EHM and remained in a collar-like formation around the haustorial neck. These observations support the suggestions that the EHM is a unique, specialized membrane and is different from the plasma membrane. Our results suggested two possibilities for the origin of the EHM: invagination of the plasma membrane coupled with membrane differentiation; or de novo synthesis of the EHM by targeted vesicle trafficking.
Gene trap as a tool for genome annotation and analysis of X chromosome inactivation in human embryonic stem cells (2004)

Human embryonic stem (ES) cells were suggested to be an important tool in transplantation medicine. However, they also play a major role in human genetics. Using the gene trap strategy, we have created a bank of clones with insertion mutations in human ES cells. These insertions occurred within known, predicted and unknown genes, and thus assist us in annotating the genes in the human genome. The insertions into the genome occurred in multiple chromosomes with a preference to larger chromosomes. Utilizing a clone where the integration occurred in the X chromosome, we have studied X-chromosome inactivation in human cells. We thus show that in undifferentiated female human ES cells both X chromosomes remain active and upon differentiation one chromosome undergoes inactivation. In the differentiated embryonic cells the inactivation is random, while in the extra-embryonic cells it is non-random. In addition, using a selection methodology, we demonstrate that in a minority of the cells partial inactivation and XIST expression occur even in the undifferentiated cells. We suggest that X chromosome inactivation during human embryogenesis, which coincides with differentiation, may be separated from the differentiation process. The genetic manipulation of human ES cells now opens new ways of analyzing chromosome status and gene expression in humans.
Membrane Stabilization of Biodegradable Polymersomes (2009)

Biodegradable polymersomes are promising vehicles for a range of applications. Their stabilization would improve many properties, including the retention and controlled release of polymersome contents, yet this has not been previously accomplished. Here, we present the first example of stabilizing fully biodegradable polymersomes through acrylation of the hydrophobic terminal end of polymersome-forming poly(caprolactone-b-ethylene glycol). Exposure of the resulting polymersomes loaded with a hydrophobic photoinitiator to ultraviolet light polymerized the acrylates, without affecting polymersome morphology or cell cytotoxicity. These stabilized polymersomes were more resistant to surfactant disruption and degradation. As an example of stabilized polymersome utility, the unintended release of doxorubicin (DOX) due to leakage from polymersomes decreased with membrane stabilization and slower sustained release was observed. Finally, DOX-loaded polymersomes retained their cytotoxicity following stabilization.
Seismic Rehabilitation of Deficient Exterior Concrete Frame Joints (2005)

The performance of rehabilitated reinforced concrete beam-column joints was compared with the response of existing joints designed to preseismic codes to assess proposed rehabilitation techniques. Six beam-column subassemblies with nonductile reinforcement detailing were tested. The joints were subjected to quasi-static load that simulates seismic forces. The first three specimens had inadequate anchorage length of the bottom beam bars. Two of them were strengthened by using carbon-fiber-reinforced polymer sheets attached to the bottom beam face and then tested. The other three specimens had no steel ties installed in the joint zone, in addition to inadequate anchorage length of the beam bars. Two of the beam-column joints were strengthened by glass-fiber-reinforced polymer jackets of the joint zone and steel rods or plates. The rehabilitation techniques were found effective in eliminating the brittle joint shear and steel bar bond-slip failure modes, and ductile beam hinging instead occurred.
