Bioremediation techniques–classification based on site of application: principles, advantages, limitations and prospects (2016)

Environmental pollution has been on the rise in the past few decades owing to increased human activities on energy reservoirs, unsafe agricultural practices and rapid industrialization. Amongst the pollutants that are of environmental and public health concerns due to their toxicities are: heavy metals, nuclear wastes, pesticides, green house gases, and hydrocarbons. Remediation of polluted sites using microbial process (bioremediation) has proven effective and reliable due to its eco-friendly features. Bioremediation can either be carried out ex situ or in situ, depending on several factors, which include but not limited to cost, site characteristics, type and concentration of pollutants. Generally, ex situ techniques apparently are more expensive compared to in situ techniques as a result of additional cost attributable to excavation. However, cost of on-site installation of equipment, and inability to effectively visualize and control the subsurface of polluted sites are of major concerns when carrying out in situ bioremediation. Therefore, choosing appropriate bioremediation technique, which will effectively reduce pollutant concentrations to an innocuous state, is crucial for a successful bioremediation project. Furthermore, the two major approaches to enhance bioremediation are biostimulation and bioaugmentation provided that environmental factors, which determine the success of bioremediation, are maintained at optimal range. This review provides more insight into the two major bioremediation techniques, their principles, advantages, limitations and prospects.
A mobile real-time bioengineering front end system. (1993)

In the study of physiological system dynamics, a mobile Front End System is needed in faithfully monitoring and recording physiological signals at various experimental sites. Local real-time mode operation is required at the site of the experiment such that the significant dynamic response or event from the subject can be easily captured and displayed as the experiment progresses. An additional requirement is the interfacing with the campus computer network such that numerous network computing resources can be employed in further processing of the captured data. The system is configured by using general-purpose components such as a 50MHz PC-486, a DAS-HRES data acquisition board and some other necessary peripheral devices. An algorithm has been developed for the continuous manipulation of two queues to maintain the real-time task scheduling. Traces can be played back in forward or reverse mode at varied speed after the recording has been made. As desired, any trace segment can be picked up in the play back mode from the huge data files. The system is incorporated in a live subject bioinstrumentation laboratory and has the capability of monitoring signals from four simultaneously experimental setups. The signal types involved are membrane potentials, ECG, EMG, blood pressure, and respiratory flows and gas concentrations.
Distribution Locational Marginal Pricing Through Quadratic Programming for Congestion Management in Distribution Networks (2014)

This paper presents the distribution locational marginal pricing (DLMP) method through quadratic programming (QP) designed to alleviate the congestion that might occur in a distribution network with high penetration of flexible demands. In the DLMP method, the distribution system operator (DSO) calculates dynamic tariffs and publishes them to the aggregators, who make the optimal energy plans for the flexible demands. The DLMP through QP instead of linear programing as studied in previous literatures solves the multiple solution issue of the aggregator optimization which may cause the decentralized congestion management by DLMP to fail. It is proven in this paper, using convex optimization theory, the aggregator's optimization problem through QP is strictly convex and has a unique solution. The Karush-Kuhn-Tucker (KKT) conditions and the unique solution of the aggregator optimization ensure that the centralized DSO optimization and the decentralized aggregator optimization converge. Case studies using a distribution network with high penetration of electric vehicles (EVs) and heat pumps (HPs) validate the equivalence of the two optimization setups, and the efficacy of the proposed DLMP through QP for congestion management.
The effect of adrenaline on acetylcholine synthesis after blockade of alpha- and beta-adrenergic receptors in vitro. (1977)

The aim of the present work was to explain the mechanism of the stimulating effect of adrenaline (A) on acetylcholine (ACh) synthesis. This action is exerted most probably through the beta- adrenergic receptors, since propranolol and oxprenolol inhibit the stimulating effect of adrenaline on acetylcholine synthesis in the rat cerebral cortex in vitro. Dihydroergotamine does not show such effect. Practolol and phentolamine decrease the spontaneous synthesis of ACh in concentration several times lower than that inhibiting the ACh synthesis stimulated by adrenaline. It is suggested that adrenaline-induced stimulation of ACh synthesis in the rat cerebral cortex is not due to cyclic AMP, because noradrenaline (NA) does not increase ACh synthesis either in vivo or in vitro, although it activates the adenyl cyclase. NA on the other hand activates ACh synthesis in the calcium-free medium, which inhibits activating effect of NA on adenyl cyclase. Moreover it was found that cyclic AMP depresses ACh synthesis in the rat cerebral cortex in vitro.
Distal Biceps Tendon Repair Using the Toggle Loc With Zip Loop (2008)

This article introduces the Toggle Loc with Zip Loop as a fixation technique for a single-incision distal biceps tendon repair. The ease with which the Toggle Loc can be attached to the ruptured tendon is a distinct advantage of this technique. Because the suture loops (Zip Loop) can be shortened after the tendon is sutured over it, the surgeon can attach the implant to the tendon away from the wound. The implant can then be inserted and seated on the dorsal cortex of the radius prior to final tendon reinsertion and tensioning of the repair. This allows for a technically easier reinsertion while maintaining appropriate elbow flexion and rotation.

Visualizing hyperbolic space (1992)

We briefly discuss hyperbolic geometry, one of the most useful and important kinds of non-Euclidean geometry. Rigid motions of hyperbolic space may be represented by 4 x 4 homogeneous transformations in exactly the same way as rigid motions of Euclidean space. This is a happy situation for those of us interested in visualizing what life in hyperbolic space might be like, because it means we can use existing graphics hardware and software libraries to animate scenes in hyperbolic space. We present formulas for computing reflections, translations, and rotations in hyperbolic space. These are a bit more complicated than the corresponding formulas for Euclidean geometry, which emphasizes our need for graphics libraries which allow completely arbitrary 4 X 4 transformations.
Analysis and Design of a Differentially-Fed Frequency Agile Microstrip Patch Antenna (2010)

The design of a frequency agile microstrip patch antenna is described that is readily interfaced with differential RF transceivers. By integrating three pairs of varactor diodes with the patch antenna, and tuning them in unison, frequency tuning ratios approaching 2 are possible with the design. This is made possible by the intrinsically broadband nature of the differential feeding scheme used. An intuitive equivalent circuit for predicting the port characteristics of the antenna is presented. Moreover, the circuit is shown to be highly accurate in predicting losses produced by the varactor diodes and the consequent radiation efficiency of the antenna. To the best of the authors' knowledge, this is the first time a detailed analysis of the effect of varactor diode losses has been undertaken in frequency agile antennas using an equivalent circuit. The equivalent circuit model is subsequently validated using full-wave simulations and experimental measurements of an antenna operating in the 2-4 GHz range.
Voltaglue Electroceutical Adhesive Patches for Localized Voltage Stimulation (2019)

Electroceuticals have been proposed as nerve- and tissue-stimulating therapeutics for diverse ailments such as fracture repair, Parkinson's disease, diabetes, hypertension, and wound healing. However, academic and clinical investigations of electroceutical hypotheses remain intangible due to the lack of suitable interfaces required for the application of uniform electric fields to localized tissues. There is an unmet need to develop materials that match the mechanical properties of soft tissues, are electrically conductive, and can flex to accommodate body movements. Herein, the design of a flexible resistive substrate and voltage-activated adhesive-based "electroceutical plaster" is demonstrated, which generates bound electric fields. The electric fields generated by the resistive substrate can interact with the active component in the voltage-activated adhesive. Structure-activity relationships of applied voltage and current bias on electrorheology and tissue adhesion are investigated. Electrocuring migration is observed, where curing commences near the cathode and progresses toward the anode. A potential electroceutical dressing with a tunable lap shear adhesion of 20-65 kPa is introduced for evaluation of electroceutical therapies.
The Labeled Multi-Bernoulli Filter (2014)

This paper proposes a generalization of the multi- Bernoulli filter called the labeled multi-Bernoulli filter that outputs target tracks. Moreover, the labeled multi-Bernoulli filter does not exhibit a cardinality bias due to a more accurate update approximation compared to the multi-Bernoulli filter by exploiting the conjugate prior form for labeled Random Finite Sets. The proposed filter can be interpreted as an efficient approximation of the δ-Generalized Labeled Multi-Bernoulli filter. It inherits the advantages of the multi-Bernoulli filter in regards to particle implementation and state estimation. It also inherits advantages of the δ-Generalized Labeled Multi-Bernoulli filter in that it outputs (labeled) target tracks and achieves better performance.
The Terminally Redundant, Nonpermuted Genome of<i>Listeria</i>Bacteriophage A511: a Model for the SPO1-Like Myoviruses of Gram-Positive Bacteria (2008)

ABSTRACT Only little information on a particular class of myoviruses, the SPO1-like bacteriophages infecting low-G+C-content, gram-positive host bacteria ( Firmicutes ), is available. We present the genome analysis and molecular characterization of the large, virulent, broad-host-range Listeria phage A511. A511 contains a unit (informational) genome of 134,494 bp, encompassing 190 putative open reading frames (ORFs) and 16 tRNA genes, organized in a modular fashion common among the Caudovirales . Electron microscopy, enzymatic fragmentation analyses, and sequencing revealed that the A511 DNA molecule contains linear terminal repeats of a total of 3,125 bp, encompassing nine small putative ORFs. This particular genome structure explains why A511 is unable to perform general transduction. A511 features significant sequence homologies to Listeria phage P100 and other morphologically related phages infecting Firmicutes such as Staphylococcus phage K and Lactobacillus phage LP65. Equivalent but more-extensive terminal repeats also exist in phages P100 (∼6 kb) and K (∼20 kb). High-resolution electron microscopy revealed, for the first time, the presence of long tail fibers organized in a sixfold symmetry in these viruses. Mass spectrometry-based peptide fingerprinting permitted assignment of individual proteins to A511 structural components. On the basis of the data available for A511 and relatives, we propose that SPO1-like myoviruses are characterized by (i) their infection of gram-positive, low-G+C-content bacteria; (ii) a wide host range within the host bacterial genus and a strictly virulent lifestyle; (iii) similar morphology, sequence relatedness, and collinearity of the phage genome organization; and (iv) large double-stranded DNA genomes featuring nonpermuted terminal repeats of various sizes.
Effects of Triacetoxyvinylsilane as SEI Layer Additive on Electrochemical Performance of Lithium Metal Secondary Battery (2007)

The effects of a solid electrolyte interface (SEI) additive, triacetoxyvinylsilane (VS), on the electrochemical performance of a lithium metal secondary battery were investigated. When VS was added to the electrolyte, no lithium dendrite on the lithium metal surface after precycling was observed and thereby the lowest interfacial resistance of the unit cell could be achieved. With these reasons, the capacity of the unit cell based on the electrolyte containing VS could maintain about 80% of the initial capacity after at a high charge/discharge current density (C/2, ).

Calibrating a Real-Time Traffic Crash-Prediction Model Using Archived Weather and ITS Traffic Data (2006)

Growing concern over traffic safety has led to research efforts directed towards predicting freeway crashes in Advanced Traffic Management and Information Systems (ATMIS) environment. This paper aims at developing a crash-likelihood prediction model using real-time traffic-flow variables (measured through series of underground sensors) and rain data (collected at weather stations) potentially associated with crash occurrence. Archived loop detector and rain data and historical crash data have been used to calibrate the model. This model can be implemented using an online loop and rain data to identify high crash potential in real-time. Principal component analysis (PCA) and logistic regression (LR) have been used to estimate a weather model that determines a rain index based on the rain readings at the weather station in the proximity of the freeway. A matched case-control logit model has also been used to model the crash potential based on traffic loop data and the rain index. The 5-min average occupancy and standard deviation of volume observed at the downstream station, and the 5-min coefficient of variation in speed at the station closest to the crash, all during 5-10 min prior to the crash occurrence along with the rain index have been found to affect the crash occurrence most significantly.
Bookmark‐agent: Sharing of bookmarks for search assists (2002)

Abstract The Bookmark‐Agent is a system which references bookmark files that register URLs which users are interested in, and then shares information among users. This engine can perform information searches more effectively than existing search engines. When a user is searching for a Web page by browsing, the agent searches for Web pages thought to represent what the user wants from among bookmarks, then presents a list in hyperlink form to the user's browser. In addition, the agent can also search other users' bookmarks by communicating with other users' agents. By using this agent in a small‐scale group consisting of users with similar interests, information which has been filtered by users, that is, bookmarks, can be used. As a result, the Bookmark‐Agent can display Web pages with a precision level higher than that of existing search engines. This is confirmed by experiments using six users for the purpose of evaluating the performance of the Bookmark‐Agent. © 2002 Wiley Periodicals, Inc.

ViViT: A Video Vision Transformer (2021)

We present pure-transformer based models for video classification, drawing upon the recent success of such models in image classification. Our model extracts spatiotemporal tokens from the input video, which are then encoded by a series of transformer layers. In order to handle the long sequences of tokens encountered in video, we propose several, efficient variants of our model which factorise the spatial- and temporal-dimensions of the input. Although transformer-based models are known to only be effective when large training datasets are available, we show how we can effectively regularise the model during training and leverage pretrained image models to be able to train on comparatively small datasets. We conduct thorough ablation studies, and achieve state-of-the-art results on multiple video classification benchmarks including Kinetics 400 and 600, Epic Kitchens, Something-Something v2 and Moments in Time, outperforming prior methods based on deep 3D convolutional networks.
Shoulder Pain and Subluxation After Stroke: Correlation or Coincidence? (1996)

These results do not support a strong relationship between shoulder subluxation and pain after stroke. Appropriate precautions should be taken to prevent range of motion limitations that may result in shoulder pain.
A Region Based Approach for SAR Image Co-registration (2008)

A novel region based SAR image co-registration method is proposed, which formulates the problems as an optimization with respect to co-registration and recognition simultaneously based on statistics. The experimental results on ERS1/2 SAR datasets and a series of simulated experiments demonstrate the robustness of the proposed approach with respect to the conventional tie-patch method.
Learning support order for manipulation in clutter (2013)

Understanding positional semantics of the environment plays an important role in manipulating an object in clutter. The interaction with surrounding objects in the environment must be considered in order to perform the task without causing the objects fall or get damaged. In this paper, we learn the semantics in terms of support relationship among different objects in a cluttered environment by utilizing various photometric and geometric properties of the scene. To manipulate an object of interest, we use the inferred support relationship to derive a sequence in which its surrounding objects should be removed while causing minimal damage to the environment. We believe, this work can push the boundary of robotic applications in grasping, object manipulation and picking-from-bin, towards objects of generic shape and size and scenarios with physical contact and overlap. We have created an RGBD dataset that consists of various objects used in day-to-day life present in clutter. We explore many different settings involving different kind of object-object interaction. We successfully learn support relationships and predict support order in these settings.
Methicillin Resistance in <i>Staphylococcus aureus</i> and Coagulase‐Negative Staphylococci: Epidemiological and Molecular Aspects (2007)

Infections caused by the genus Staphylococcus are of great importance for human health. Staphylococcus species are divided into coagulase-positive staphylococci, represented by S. aureus, a pathogen that can cause infections of the skin and other organs in immunocompetent patients, and coagulase-negative staphylococci (CNS) which comprise different species normally involved in infectious processes in immunocompromised patients or patients using catheters. Oxacillin has been one of the main drugs used for the treatment of staphylococcal infections; however, a large number of S. aureus and CNS isolates of nosocomial origin are resistant to this drug. Methicillin resistance is encoded by the mecA gene which is inserted in the SCC mec cassette. This cassette is a mobile genetic element consisting of five different types and several subtypes. Oxacillin-resistant strains are detected by phenotypic and genotypic methods. Epidemiologically, methicillin-resistant S. aureus strains can be divided into five large pandemic clones, called Brazilian, Hungarian, Iberian, New York/Japan and Pediatric. The objective of the present review was to discuss aspects of resistance, epidemiology, genetics and detection of oxacillin resistance in Staphylococcus spp., since these microorganisms are increasingly more frequent in Brazil.
Flexural resonance measurements of clamped and partially clamped disks excited by nanosecond laser pulses (1986)

Nanosecond pulses from a Nd:YAG laser are used to excite clamped aluminum disks to resonance. The first two flexural vibration modes are shown to be in agreement with classical plate theory. This theory is then applied to the case of flat-bottomed holes in aluminum plates, when the remainder of the plate below the hole may be said to be partially clamped. It is shown that the theory can still be used over a well-defined regime. In addition, the depth of the hole can be obtained from the ring-around longitudinal ultrasonic pulse generated by the laser. A combination of these two techniques, therefore, allows a sizing of circularlike flaws in laminations lying close to a sample’s surface.
Life–style changes and coronary heart disease: The influence of nonpharmacologic interventions (1995)

Life-style habits such as diet and exercise can have powerful affects on the development and progression of coronary heart disease. This article presents evidence supporting the use of these two modalities in the treatment of coronary heart disease. Diet is discussed in terms of cholesterol, obesity, fiber, fish oils, and antioxidants. Exercise is discussed in terms of the preparation for and the components of an exercise program. Appropriate nursing interventions are offered for use when working with patients who must modify their dietary or exercise habits.
