Using FSR based muscule activity monitoring to recognize manipulative arm gestures (2007)

We present an experiment that investigates the usefulness of muscle monitoring information from arm mounted force sensitive resistors (FSR) for activity recognition. The paper is motivated by previous work that has demonstrated the feasibility of using FSRs for muscle activity monitoring (on leg muscles) and presented some initial signals related to distinct arm activities. We systematically investigate the performance of an FSR system on 16 different manipulative gestures and 2 subjects. The aim is to test the limits of the system, compare them to established sensing modalities (3D acceleration and gyro), and establish the value of combining FSR with other sensing modalities. We also present a hardware setup that addresses key problems that were identified in previous work: large variations in the attachment force and sensor placement accuracy issues. For all classifiers the overall accuracy of the FSR system is in the middle between the accelerometer (between 5% and 10% better) and the gyro (between 2% and 11% worse). Adding FSRs to another sensor improves the accuracy by 1% to 29%.
Antiatherosclerotic Actions of Isradipine (1992)

Isradipine, a calcium antagonist of the dihy-dropyridine type, shows antiatherosclerotic actions that interfere with all three main mechanisms of atherosclerosis. These actions are mediated by the release of prostaglandin I:2 and endothelium-derived relaxing factor, and the subsequent elevation of intracellular adenosine-3′,5′-cyclic phosphate and 3′,5′-guanosine monophosphate, re- spectively. These mechanisms have been proven in vitro and in animal models. Preliminary data in humans suggest that these mechanisms have clinical relevance in the long-term treatment of patients as well.
Comparative safety profile between "modern" trabeculectomy and non-penetrationg deep sclerectomy. (2006)

Whether surgery was augmented with intraoperative antimetabolite or not, mTRAB revealed as a priority to be associated with comparable and even less complications than deep sclerectomy. Owing to the limitations of our study and until further confirmation, our results have suggested that mTRAB was associated with a slightly more important IOP reduction as well as higher success rates than NPDS.

Carers' perceptions of pain in people with dementia: a grounded theory approach. (2004)

The purpose of this Grounded Theory based study was to add to the limited understanding about the perception and observation of pain by the formal and informal carers of people with dementia. Thirty-one carers talked about how they know when their person with dementia has pain. Findings showed there is no one set of signs or behaviours that indicate pain in all people with dementia. However, a common pain assessment process amongst carers involved being able to detect deviation from normal behaviours based upon their intimate knowledge of what is normal for their person. A central hypothesis was thus generated from the data that considered that effective pain assessment for people with dementia is dependent on carers having an intimate knowledge of the individual's normal state of being with dementia. Implications for nursing practice are discussed.
Viable Tumor Tissue Adherent to Needle Applicators after Local Ablation: A Risk Factor for Local Tumor Progression (2011)

Viable tumor cells adherent to the needle applicators were found after ablation of 26.7% of patients. An independent risk factor for viable cells adherent to the needle applicators is the omission of track ablation. We recommend using only RFA devices that have track ablation functionality. Adherence of viable tumor cells to the needle applicator after local ablation was an independent risk factor for LTP.
Nitrogen-induced fcc phase in rf sputtered Co–Cr films having the hcp phase and perpendicular magnetic anisotropy (1982)

The presence of as little as 2.3×10−5 Pa (1.73×10−7 Torr) of residual nitrogen gas in an rf sputtering chamber has been found to promote the formation of the fcc phase in Co-Cr films under conditions otherwise favorable to the formation of the hcp phase. The fcc phase follows the disorientation of the hcp phase as the nitrogen partial pressure or throughput increases. The occurrence of the fcc phase is directly related to the partial pressure or throughput of nitrogen in the system as shown using controlled leaks of both pure nitrogen and air. The nitrogen may destroy the columnar microstructure and the film perpendicular magnetic anisotropy which is due to the well-oriented hcp phase. This sensitivity to nitrogen in the background gases makes it necessary to achieve a low background pressure in the sputtering chamber if films with perpendicular magnetic anisotropy are to be obtained.
STANDING SEDATION IN AFRICAN ELEPHANTS (LOXODONTA AFRICANA) USING DETOMIDINE–BUTORPHANOL COMBINATIONS (2005)

Standing sedation was provided for 14 clinical procedures in three African elephants (Loxodonta africana) managed by combined protected and modified-protected contact and trained through operant conditioning. An initial hand-injection of detomidine hydrochloride and butorphanol tartrate at a ratio of 1:1 on a microg:microg basis was administered intramuscularly, with a dosage range of 50-70 mg (12.9-19.7 microg/kg) for each drug. The initial injection resulted in adequate sedation for initiation and completion of eight procedures, whereas supplemental doses were required for the remaining procedures. The dosage range for the supplemental injections of each drug was 4.0-7.3 microg/kg. Initial effect was noted within 3.0-25 min (mean = 11.6 min, SD +/- 5.9 min), with maximal effect occurring at 25-30 min for those procedures not requiring supplementation. In all but one procedure, this effect was maintained until the end of the procedure, which ranged from 47 to 98 min (mean = 74.7 min, SD +/- 18.8 min). No cardiac or respiratory depression was appreciated. Recovery after administration of reversal agents was rapid and complete, ranging from 2 to 20 min (mean = 9.0 min, SD +/- 7.0 min). On the basis of the authors' experience, recommended dosage ranges for reversal agents would be intravenous yohimbine (73.4-98.5 microg/kg), intravenous naltrexone (48.9-98.5 microg/kg), and intramuscular naltrexone (73.4-98.5 microg/kg). Approximately one-third to one-half of the total naltrexone dose should be administered intravenously. Mild adverse side effects limited to the gastrointestinal tract were observed in association with five procedures including abdominal distention with or without transient anorexia. Administration of reversal agents, encouraging exercise and water consumption, and administration of flunixin meglumine were helpful in the resolution of signs. In addition to gastrointestinal signs, slight ataxia was observed before initiation of surgical stimulation during one procedure in which 19.7 microg/kg of each drug was administered. On the basis of the procedures that did not require supplementation to initiate treatment and taking into consideration the potential for ataxia at higher doses, a starting dosage range of 14.7-16.2 microg/kg of both detomidine and butorphanol in a ratio of 1:1 on a microg:microg basis administered i.m. simultaneously is recommended.
Virtual concatenation tutorial: enhancing SONET/SDH networks for data transport (2001)

Synchronous optical network (SONET) and synchronous digital hierarchy (SDH) contiguous concatenation have enabled high-speed networking in both metro and core networks for many narrow-band and broadband services including digital subscriber loop (DSL), cable, and Ethernet. Ironically, the tremendous success and rise of data traffic have, in part, put the focus on some of the inefficiencies and inflexibilities of SDH contiguous concatenation. Here I examine these shortcomings, survey available bandwidth efficiency techniques for data transport, examine two relatively new mechanisms known as virtual concatenation and link capacity adjustment scheme (LCAS) that address these issues, and finally present several potential applications for these technologies.
Point Cloud-Based Automatic Assessment of 3D Computer Animation Courseworks (2016)

Computer-supported assessment tools can bring significant benefits to both students and teachers. When integrated in traditional education workflows, they may help to reduce the time required to perform the evaluation and consolidate the perception of fairness of the overall process. When integrated within on-line intelligent tutoring systems, they could provide students with a timely feedback and support self-assessment activities. The current work presents an alternative approach (and not just a “yet-another-implementation”) to the problem of automatically evaluating technical skills needed to create 3D computer animations. Although some solutions have been reported already in the literature, their applicability is partially constrained, as they require the teaching staff to define evaluation criteria that are strictly linked to the particular animation technique being assessed. Students are forced to operate in environments where they can only perform a part of the required animation steps, by using a pre-defined set of techniques and tools. To address such limitations, the proposed system exploits shapeand time-based features extracted from the 3D point clouds (i.e., the set of data points) describing animated geometries, which are independent of the particular animation techniques used. Experimental observations collected in the evaluation of course assignments in which students were asked to recreate 3D animations of deformable meshes prepared by the teaching staff showed a good correlation between automatic and manual evaluations. Obtained results confirmed the ability of the proposed approach to cope with heterogeneous evaluation tasks in which the relevant learning outcomes can be properly considered.
Aloe Genus Plants: From Farm to Food Applications and Phytopharmacotherapy (2018)

<i>Aloe</i> genus plants, distributed in Old World, are widely known and have been used for centuries as topical and oral therapeutic agents due to their health, beauty, medicinal, and skin care properties. Among the well-investigated <i>Aloe</i> species are <i>A. arborescens</i>, <i>A. barbadensis</i>, <i>A. ferox</i>, and <i>A. vera</i>. Today, they account among the most economically important medicinal plants and are commonly used in primary health treatment, where they play a pivotal role in the treatment of various types of diseases via the modulation of biochemical and molecular pathways, besides being a rich source of valuable phytochemicals. In the present review, we summarized the recent advances in botany, phytochemical composition, ethnobotanical uses, food preservation, and the preclinical and clinical efficacy of <i>Aloe</i> plants. These data will be helpful to provide future directions for the industrial and medicinal use of <i>Aloe</i> plants.
Base Catalysts Derived from Hydrocalumite for the Transesterification of Sunflower Oil (2009)

This work investigates the use of a layered Ca−Al double hydroxide (hydrocalumite) as precursor, after its thermal activation, of base catalysts for the methanolysis of sunflower oil. Above 750 °C, hydrocalumite is transformed into a mixture of CaO and mayenite (Ca12Al14O33). Another Ca−Al material obtained under similar experimental conditions was also studied, but using the Ca/Al molar ratio of the mayenite, 12:14. A sunflower oil conversion of 97% has been reached with a methanol/oil molar ratio of 12:1, a reaction temperature of 60 °C, and 1 wt % of the CaAl-2:1 catalyst. This catalyst needs to be previously activated at 500 °C in helium atmosphere, which is an activation temperature at least 200 °C lower than that required to revert the CO2 poisoning in bulk and supported CaO catalysts.

Pulse delay measurements in the zero-material-dispersion region for germanium- and phosphorus-doped silica fibres (1978)

Wavelength-dependent pulse dispersion in germanium- and phosphorus-doped silica fibres of different concentrations was measured using mode-locked subnanosecond pulses in the 1.064–1.55 μm wavelength range. Zero dispersion for GeO2-SiO2 fibres was observed in the 1.3–1.33 μm region depending on the concentration. P2O5-doped silica fibres showed zero dispersion near 1.28 μm, independent of doping concentration.
An analytical solution to the budget-pacing problem in programmatic advertising (2019)

Recent developments in the advertising industry have motivated changes in the way adinventory is purchased. Among the main innovations in this direction is the use of automated strategies deciding in real time the price they are willing to pay in order to expose a potential customer to a given message. In particular, once a strategic optimization layer determines the budget allocated to each audience and type of inventory, it remains the tactical problem of how to schedule the budget-delivery over time. This is the so called budget-pacing problem. In this article, we provide a framework to analyze this problem using variational calculus techniques, allowing to treat general settings and to obtain a simple characterization of the optimality conditions which leads to an implementation in the form of a feedback-control system. Our results are consistent with the fluid-limit approximation found in [4], which treats the problem using stochastic optimal control techniques.
Depletion of Arginine by Recombinant Arginine Deiminase Induces nNOS-Activated Neurotoxicity in Neuroblastoma Cells (2014)

The abnormal regulation of inducible nitric oxide synthase (iNOS) and neuronal nitric oxide synthase (nNOS) is associated with neurodegenerative disorders. Recombinant arginine deiminase (rADI) is a selective NO modulator of iNOS and eNOS in endothelial cells, and it also exhibits neuroprotective activity in an iNOS-induced neuron-microglia coculture system. However, the effect of rADI on nNOS remains unknown. Addressing this issue is important for evaluating the potential application of rADI in neurodegenerative diseases. SH-SY5Y cells were treated with N-methyl-D-aspartic acid (NMDA) to activate nNOS. NMDA increased NO production by 39.7 ± 3.9% via nNOS under arginine-containing conditions, but there was no significant increase in both arginine-free and rADI pretreated arginine-containing (citrulline) buffer. Subsequently, neither NMDA nor rADI alone caused cytotoxicity, whereas cotreatment with NMDA and rADI resulted in dissipation of the cell mitochondrial membrane potential and decreased cell viability. The mechanism of rADI cytotoxicity in the presence of NMDA is caused by the inhibition of NO production via nNOS mediated by the NMDA receptor, which was abolished when extracellular arginine was absent, even in the presence of citrulline. rADI not only reduced NO production but also caused cellular toxicity in nNOS-activated SH-SY5Y cells, suggesting a dual role for rADI in NOS-mediated neurotoxicity.
Removal of local field gradient artifacts in T<sub>2</sub>*‐weighted images at high fields by gradient‐echo slice excitation profile imaging (1998)

Development of high magnetic field MRI techniques is hampered by the significant artifacts produced by B0 field inhomogeneities in the excited slices. A technique, gradient-echo slice excitation profile imaging (GESEPI), is presented for recovering the signal lost caused by intravoxel phase dispersion in T2*-weighted images. This technique superimposes an incremental gradient offset on the slice refocusing gradient to sample k-space over the full range of spatial frequencies of the excitation profile. A third Fourier transform of the initial two-dimensional image set generates an image set in which the artifacts produced by the low-order B0 inhomogeneity field gradients in the sample are separated and removed from the high-order microscopic field gradients responsible for T2* contrast. Application to high field brain imaging, at 3.0 T for human and at 9.4 T for immature rat imaging demonstrates the significant improvement in quality of the T2*-weighted contrast images.
Quantitative imaging of electron density and effective atomic number using phase contrast CT (2010)

Compared to single energy CT, which only provides information for x-ray linear attenuation coefficients, dual-energy CT is able to obtain both the electron density and effective atomic number for different materials in a quantitative way. In this study, as an alternative to dual-energy CT, a novel quantitative imaging method based on phase contrast CT is presented. Rather than requiring two projection data sets with different x-ray energy spectra, diffraction-grating-based phase contrast CT is capable of reconstructing images of both linear attenuation and refractive index decrement from the same projection data using a single x-ray energy spectra. From the two images, quantitative information of both the electron density and effective atomic number can be extracted. Two physical phantoms were constructed and used to validate the presented method. Experimental results demonstrate that (1) electron density can be accurately determined from refractive index decrement through a linear relationship, and (2) the effective atomic number can be explicitly derived from the ratio of the linear attenuation to refractive index decrement using a power function plus a constant. The presented method will provide insight into the technique of material separation and find its use in medical and industrial applications.
Immunization against cholecystokinin decreases appetite in lambs (1992)

The effects of immunization against cholecystokinin (CCK) on feed intake, weight gain, and carcass characteristics were studied in sheep. Nine wether lambs at 10 wk of age were immunized with a conjugate of sulphated CCK octapeptide and human serum globulin or against human globulin alone. All CCK-immunized lambs produced antibodies, and the average titer 5 wk after the primary immunization was calculated to be sufficient to bind normal circulating levels of CCK. Mean daily feed intakes and BW were similar in the CCK-immunized and the control-immunized groups at the start of treatment, but after immunization, feed intake, appetite, and BW gain were decreased in the CCK-immunized animals. There was no effect on carcass composition or organ growth relative to body growth. It is concluded that the immunization procedure used in this study may have potentiated the actions of CCK rather than neutralizing its action as an appetite regulator.
Modal gain in a semiconductor nanowire laser with anisotropic bandstructure (2004)

We investigate optical gain for the modes guided by semiconductor nanowires. We focus on optically anisotropic wurtzite-type semiconductors (such as GaN) and the situation when the optical axis of the crystal coincides with the geometrical axis of the nanowire. For GaN nanowire lasers, the calculation of the modal gain requires the knowledge of two confinement factors for a given mode and two gain coefficients for the bulk crystal. We show that the confinement factors for nanowire lasers are very large in comparison to those for heterostructure lasers, and can even exceed unity. To estimate the bulk gain in GaN we use the free-carrier model and emphasize the importance of accounting for anisotropy of gain. Using the calculated confinement factors and bulk gain, we predict that free-standing nanowires with small radius (R /spl lsim/ 70 nm) lase into the HE/sub 11/ mode, thicker nanowires (70 nm /spl lsim/ R /spl lsim/ 90 nm) lase into the TE/sub 01/ mode.
Towards Plug and Play in Home and Building Automation Networks (2006)

High configuration cost hampers the adoption of powerful home automation solutions. Automating the necessary configuration steps will alleviate this problem. The article defines the task of "plug and play" in the context of a distributed control system built from smart sensors and actuators and the network management services involved. It gives an overview of existing approaches and outlines the requirements for a comprehensive plug and play solution as well as work-in-progress toward this goal.
