Thermal analysis of ultrathin, compliant sensors for characterization of the human skin (2013)

Recent work establishes that ultrathin, stretchable sensors can enable high precision thermal characterization of the skin, with capabilities for spatial mapping, in forms that avoid irritation, thermal or mechanical loads on natural behaviors, or motion artifacts. The results have potential for use in cardiovascular screening, skin hydration sensing, and local skin heating and thermal therapy. A theoretical framework for understanding the thermal behavior of these types of sensors is critically important for interpreting the data and identifying optimized designs. This paper presents an analytical model, validated by the finite element method and experiments, for this purpose. The sensor temperature is obtained analytically in terms of material and geometric parameters. A scaling law for the sensor response time shows that the normalized time depends only on the normalized sensor location and normalized thermal properties. A simple, analytic formula for the response at long times is also obtained. The results provide strategies for reducing the sensor response time and thereby for improving the device performance.
Multi-Tubular Corrosion Inspection Using a Pulsed Eddy Current Logging Tool (2013)

Abstract Tubular inspection can be split between direct measurements such as caliper logs or downhole video observation and Electromagnetic (EM) methods that measure properties sensitive to pipe thickness, with wall thinning associated with corrosion and other pipe defects. Various EM methods have been reported over the years often initially for pipeline inspection and then adapted for downhole well monitoring. These methods include Magnetic Flux Leakage (MFL) and Eddy Current (EC) measurements. Early EM methods were single frequency but later developments include multi-frequency. In this paper we report an emerging technique called Pulsed Eddy Current (PEC) which is inherently multi-frequency and in time domain is radially sensitive which enables inspection of multiple tubular thicknesses. Most inspection techniques including some EM methods are only capable of inspecting the inner most tubular or only the total thickness of multiple tubulars. However, a PEC tool can measure separate thicknesses of both inner and a second tubular. This allows quantitative corrosion evaluation of casing without removing the completion tubing. The paper covers a theoretical review of the PEC technique and development of a fast forward analytical model tied to experimental data acquired with an actual logging instrument. The fast forward model is used to ensure optimum tool design and allows development of an inverse model which realises quantitative evaluation of the corrosion within multiple tubulars from field data.
Pre-hospital portable monitoring of cerebral regional oxygen saturation (rSO2) in seven patients with out-of-hospital cardiac arrest (2016)

We could measure serial changes in cerebral rSO2 in seven patients with OHCA in the pre-hospital setting. Our data suggest that pre-hospital monitoring of cerebral rSO2 might lead to a new resuscitation strategy.
Unified compressive sensing framework for simultaneous acquisition with primary estimation (2009)

The central promise of simultaneous acquisition is a vastly improved crew efficiency during acquisition at the cost of additional post‐processing to obtain conventional source‐separated data volumes. Using recent theories from the field of compressive sensing, we present a way to systematically model the effects of simultaneous acquisition. Our formulation form a new framework in the study of acquisition design and naturally leads to an inversion‐based approach for the separation of shot records. Furthermore, we show how other inversion‐based methods, such as a recently proposed method from van Groen‐estijn and Verschuur (2009) for primary estimation, can be processed together with the demultiplexing problem to achieve a better result compared to a separate treatment of these problems.
Nanochemoprevention: Sustained Release of Bioactive Food Components for Cancer Prevention (2010)

Chemoprevention, especially through the use of naturally occurring phytochemicals capable of impeding the process of carcinogenesis at one or more steps, is an ideal approach for cancer management. Despite accomplished outcomes in preclinical settings, its applicability to humans has met with limited success for many reasons including inefficient systemic delivery and bioavailability of promising chemopreventive agents. We have recently introduced a novel concept of "nanochemoprevention" that utilizes nanotechnology for enhancing the outcome of chemoprevention (Cancer Res 69, 1712-1716, 2009). To establish the usefulness of nanochemoprevention in cancer management, we studied the efficacy of a well identified chemopreventive agent epigallocatechin-3-gallate (EGCG) encapsulated in polylactic acid (PLA) and polyethylene glycol (PEG) nanoparticles (hereafter referred to as nano-EGCG) in preclinical settings. Nano-EGCG was found to retain its biological effectiveness, with over 10-fold dose advantage compared to nonencapsulated EGCG for exerting its cell growth inhibition, proapoptotic, and angiogenic inhibitory effects. Nano-EGCG was also observed to be effective in inhibiting tumor cell growth in athymic nude mice, with over 10-fold dose advantage compared to nonencapsulated EGCG. The rate of degradation of nonencapsulated EGCG was rapid, with a complete degradation within 4 h, whereas nano-EGCG had a significantly longer half-life. This study provides a foundation for the use of nanoparticle-mediated delivery of natural products to enhance the bioavailability of active agents for their enhanced effective and chemopreventive potential. In doing this, it is hoped that perceived toxicity concerns associated with prolonged use of agents could also be minimized. Oral consumption is the most desirable and acceptable form of delivery of chemopreventive agents. One disadvantage of using PLA-PEG nanoparticles is its unstable nature in acidic environment; and therefore, it is not recommended for oral consumption. To overcome this obstacle, it will be important to develop nanoparticles encapsulating phytochemicals that are suitable for oral consumption.
An Avatar-Based Adaptation Workflow for the Web of Things (2016)

The Web of Things (WoT) extends the Internet of Things to provide users with high-level features, involving physical objects connected through Web technologies and standards. Avatar-based infrastructures is one of the most promising solution for the WoT. Avatars are component-based software agents that extend physical objects and are able to reason about contextual information. A major challenge of the WoT is to allow applications to adapt to their environment. In this paper, we propose an approach to process multi-purpose adaptation in an avatar-based WoT infrastructure. Our approach relies on a context meta-model that offers accurate granularity levels of information required for the different types of adaptation involved in WoT applications. We show how avatar components pre-process data from different sources, handle an operational context model, and respond to adaptation requests. We evaluate the performance of our approach and compare the effects of our adaptation process in different experimental conditions.
[Bovine cerebral cortex gangliosides in the treatment of radicular lesions (author's transl)]. (1980)

Bovine cerebral cortex gangliosides were given to 71 patients following surgical intervention for radicular compression of different etiologies. The extract was given for 20-25 days at daily doses of 20 mg for the first 15 days and 10 mg thereafter until completion of treatment. H reflexology was shown to be a good method for evaluating the response to therapy. Most information was gained by the use of the following parameters: AM/AH, AH/IE, and AH/number of stimulation pulses. The results have been compared with those obtained prior to surgical therapy, those collected in a series of 68 normal individuals and, finally, with those found in another series of 71 patients that were treated postoperatively with conventional measures (B vitamins, analgesics, antiinflammatory drugs, corticoids, etc.). The statistical analysis of the final data shows that the reflexologic parameters tested revert to normal quicker in the patients treated with gangliosides than in those not receiving such therapy. The authors consider the use of gangliosides of great interest in the postoperative period after surgical relief of radicular compression.
A Novel Isolation Scheme featuring Cavities in the Collector for a High-Speed 0.13μm SiGe:C BiCMOS Technology (2007)

A novel isolation scheme is presented in this work, which uses oxide filled cavities in the collector to separate the extrinsic base and collector regions.

A physical model of the extreme mantis shrimp strike: kinematics and cavitation of Ninjabot (2014)

To study the mechanical principles and fluid dynamics of ultrafast power-amplified systems, we built Ninjabot, a physical model of the extremely fast mantis shrimp (Stomatopoda). Ninjabot rotates a to-scale appendage within the environmental conditions and close to the kinematic range of mantis shrimp's rotating strike. Ninjabot is an adjustable mechanism that can repeatedly vary independent properties relevant to fast aquatic motions to help isolate their individual effects. Despite exceeding the kinematics of previously published biomimetic jumpers and reaching speeds in excess of 25 m s(-1) at accelerations of 3.2 × 10(4) m s(-2), Ninjabot can still be outstripped by the fastest mantis shrimp, Gonodactylus smithii, measured for the first time in this study. G. smithii reached 30 m s(-1) at accelerations of 1.5 × 10(5) m s(-2). While mantis shrimp produce cavitation upon impact with their prey, they do not cavitate during the forward portion of their strike despite their extreme speeds. In order to determine how closely to match Ninjabot and mantis shrimp kinematics to capture this cavitation behavior, we used Ninjabot to produce strikes of varying kinematics and to measure cavitation presence or absence. Using Akaike Information Criterion to compare statistical models that correlated cavitation with a variety of kinematic properties, we found that in rotating and accelerating biological conditions, cavitation inception is best explained only by maximum linear velocity.
Use of a Lactoferrin Assay in the Differential Diagnosis of Female Genital Tract Infections and Implications for the Pathophysiology of Bacterial Vaginosis (1996)

Vaginal lactoferrin determinations may provide a useful screen for inflammatory genital infections and identify individuals who require additional diagnostic evaluation. The observed absence of PMN in bacterial vaginosis may result from the destruction of PMN in vaginal discharge rather than the absence of a primary inflammatory response.
Uplink Ultra-Reliable Low Latency Communications Assessment in Unlicensed Spectrum (2018)

Through this paper, the performance of uplink transmissions in terms of latency and reliability in unlicensed spectrum is addressed. Our goal is to provide insights into how ultra-reliable and low latency communications behave over the unlicensed spectrum in standalone mode. Our system model is based on the MulteFire radio access technology and operates in the 5 GHz unlicensed band. Grant-free is an alternative to scheduled uplink scheme aiming at reducing the latency of uplink transmissions. With grant-free uplink, the users can transmit their uplink data without needing a specific grant. In this paper, both grant-free and scheduled uplink are analyzed with a focus on their performance in unlicensed spectrum. Based on extensive system-level simulations, we show that the grant-free approach is also suitable for latency reduction in the unlicensed spectrum under certain load conditions. Nevertheless, scheduled uplink presents some advantages when the number of grant-free users transmitting simultaneously increases.

An adaptive ARQ scheme using pragmatic TCM (2002)

We propose an adaptive automatic repeat request (ARQ) scheme using pragmatic trellis-coded modulations (TCMs) and soft-decision Viterbi decoding. The scheme adapts to the changing channel noise condition by selecting the TCM with a code rate which best matches the current channel signal-to-noise ratio (SNR). A simple and yet efficient algorithm for estimating channel SNR is also proposed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Der er gjort en del erfaringer på erhvervsskoler med mentorfunktioner, og på baggrund heraf tror vi, der kan udvikles en didaktik, som integrerer en elev-til-elev hjælpefunktion i undervisningen. Vi tror på baggrund af erfaringerne, at der er perspektiver i, at man til en hvis grad kan integrere hjælpefunktionen i undervisningsrummet, frem for at det er en særlig støttefunktion.
Large-Area Micro-Hot Embossing of Glass Materials with Glassy Carbon Mold Machined by Dicing (2006)

Micro-nano-imprinting or hot embossing is a target of interest for the industrial production of micro- and nano-devices from the aspect of low cost. In fluidic micro electromechanical systems (MEMS) applications, polymer materials have been widely employed to fabricating economical products owing to their low cost. However, glasses are much more suitable for higher-temperature applications or under more adverse chemical environments. Moreover, the UV absorption of glass materials is much lower than that of polymers, which is an advantage for bioanalysis. In optical MEMS as well, glasses are good candidate materials with which to achieve good optical properties, such as a high refractive index and a low UV absorption. In our previous study, micro/nano imprinting was developed for glass using glassy carbon (GC) mold prepared by focused ion beam (FIB) machining. The disadvantages of FIB machining are the limited area of etching and long machining time. The typical area in FIB machining is less than 0.25 mm2. This is the reason we tried using GC mold fabricated using dicing machine. Micro-hot-embossed test structures were successfully demonstrated with a high fidelity. These fabricated microstructures can be applied to the fabrication of microchamber arrays used for PCR analysis.
Semantic resource allocation with historical data based predictions (2010)

One of the most important issues for Service Providers in Cloud Computing is delivering a good quality of service. This is achieved by means of the adaptation to a changing environment where different failures can occur during the execution of different services and tasks. Some of these failures can be predicted taking into account the information obtained from previous executions. The results of these predictions will help the schedulers to improve the allocation of resources to the\ndifferent tasks. In this paper, we present a framework which uses semantically enhanced historical data for predicting the behavior of tasks and resources in the system, and allocating the resources according to these predictions.
Act No. 16.045 of 2 June 1989 prohibiting all discrimination that violates the principle of equality of treatment and opportunities for both sexes in all sectors of labor activity. (1989)

The plaintiffs, unions and employees, claimed that the defendant employer's fetal protection policy, which banned fertile women from working in positions where they incurred high lead exposure, constituted sex discrimination contrary to Title VII of the Civil Rights Act of 1964. The US Court of Appeals for the 7th Circuit held that the policy was valid under either a business necessity or bona fide occupational qualification theory. It noted that the scientific data available showed that the risk of harming the fetus through lead exposure was restricted to fertile women and, thus, the difference between the treatment of men and women was based on real physical differences. It also ruled that the plaintiffs had failed to show that less discriminatory alternatives would be able to protect fetuses as effectively as the defendant's policy.
The effects of fenoldopam, a selective dopamine receptor agonist, on systemic and renal hemodynamics in normotensive subjects (1999)

Fenoldopam increased renal blood flow in a dose-dependent manner compared with placebo, and, at the lowest dose, significantly increased renal blood flow occurred without changes in systemic blood pressure or heart rate. These findings will be useful in designing future studies exploring the role of fenoldopam in preventing or treating renal failure in patients who are not hypertensive.
Importance of specific guanosine N7-nitrogens and purine amino groups for efficient cleavage by a hammerhead ribozyme (1993)

Seven modified hammerhead ribozyme/substrate complexes have been prepared in which individual purine nitrogens, the guanine N7-, the guanine N2-, or the adenine N6-nitrogen, have been excised. The modified complexes were chemically synthesized with the substitution of a single 7-deazaguanosine (c7G), inosine (I), or nebularine (purine riboside, P) base analogue as appropriate for residues G5, G8, G12, A13, A14, or A15. Two of the base analogues, c7G5 and C7G8, occur in a 19-mer ribozyme, while the remaining three residues are present in a 24-mer substrate. Under stoichiometric conditions, four of the complexes, G5c7G, G8c7G, G12c7G, and A14P, are cleaved with relatively little change in rate when compared with the native complex. Two complexes, A13P and A15P, are cleaved some 6-8-fold slower than the native complex, while the G12I complex is reduced in rate by 50-fold. Steady-state kinetic analyses indicate that the cleavage efficiencies, as measured by kcat/KM values, for the G5c7G, G8c7G, and G12c7G complexes are only marginally reduced relative to the native complex. The values for the A13P, A14P, and A15P complexes are reduced by 25-, 15-, and 60-fold, respectively. These reductions in cleavage efficiency are primarily a result of lower kcat values. By comparison, the kcat/KM value for the G12I complex is decreased 450-fold relative to the native complex and is characterized by an 8-fold increase in KM and a kcat value that is reduced nearly 60-fold. These results indicate that the N2-amino group of G12 in the hammerhead ribozyme/substrate complex is critical for efficient cleavage activity.(ABSTRACT TRUNCATED AT 250 WORDS)
Push–Pull Perfusion Sampling with Segmented Flow for High Temporal and Spatial Resolution in Vivo Chemical Monitoring (2011)

Low-flow push-pull perfusion is a sampling method that yields better spatial resolution than competitive methods like microdialysis. Because of the low flow rates used (50 nL/min), it is challenging to use this technique at high temporal resolution which requires methods of collecting, manipulating, and analyzing nanoliter samples. High temporal resolution also requires control of Taylor dispersion during sampling. To meet these challenges, push-pull perfusion was coupled with segmented flow to achieve in vivo sampling at 7 s temporal resolution at 50 nL/min flow rates. By further miniaturizing the probe inlet, sampling with 200 ms resolution at 30 nL/min (pull only) was demonstrated in vitro. Using this method, L-glutamate was monitored in the striatum of anesthetized rats. Up to 500 samples of 6 nL each were collected at 7 s intervals, segmented by an immiscible oil and stored in a capillary tube. The samples were assayed offline for L-glutamate at a rate of 15 samples/min by pumping them into a reagent addition tee fabricated from Teflon where reagents were added for a fluorescent enzyme assay. Fluorescence of the resulting plugs was monitored downstream. Microinjection of 70 mM potassium in physiological buffered saline evoked l-glutamate concentration transients that had an average maxima of 4.5 ± 1.1 μM (n = 6 animals, 3-4 injections each) and rise times of 22 ± 2 s. These results demonstrate that low-flow push-pull perfusion with segmented flow can be used for high temporal resolution chemical monitoring and in complex biological environments.
Definitions of Managed Object for the DS3/E3 Interface Type (1999)

This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes objects used for managing DS3 and E3 interfaces. This document is a companion document with Definitions of Managed Objects for the DS0 (RFC 2494 [25]), DS1/E1/DS2/E2 (RFC 2495 [17]), and the work in progress SONET/SDH Interface Types. This memo specifies a MIB module in a manner that is both compliant to the SNMPv2 SMI, and semantically identical to the peer SNMPv1 definitions.
Tyrosinase subcellular distribution and kinetic parameters in wild type and <i>c</i>‐locus mutant C57BL/6J mice (1981)

The distribution and kinetic parameters of tyrosinase (EC 1.14.-18.1) from anagen hair follicles of the C57BL/6J mouse and several c-locus mutants were investigated. The results showed that c-locus mutations not only influenced the total tyrosinase activity, but the subcellular distribution as well. The kinetic parameters of tyrosinase were not influenced by the pigment mutations, suggesting that the mutations were not influencing the structure of the enzyme.
A High-Quality Denoising Dataset for Smartphone Cameras (2018)

The last decade has seen an astronomical shift from imaging with DSLR and point-and-shoot cameras to imaging with smartphone cameras. Due to the small aperture and sensor size, smartphone images have notably more noise than their DSLR counterparts. While denoising for smartphone images is an active research area, the research community currently lacks a denoising image dataset representative of real noisy images from smartphone cameras with high-quality ground truth. We address this issue in this paper with the following contributions. We propose a systematic procedure for estimating ground truth for noisy images that can be used to benchmark denoising performance for smartphone cameras. Using this procedure, we have captured a dataset - the Smartphone Image Denoising Dataset (SIDD) - of <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">~</sub> 30,000 noisy images from 10 scenes under different lighting conditions using five representative smartphone cameras and generated their ground truth images. We used this dataset to benchmark a number of denoising algorithms. We show that CNN-based methods perform better when trained on our high-quality dataset than when trained using alternative strategies, such as low-ISO images used as a proxy for ground truth data.
