Implementation of dynamic voltage frequency scaling on a processor for wireless sensing applications (2017)

The era of internet of things (IoT) envisions a world where electronics is integrated with our environment. This can be achieved with ubiquitous low power sensing devices. It is challenging to achieve low power computing in the IoT paradigm since most applications are data-centric. However, typical applications have low duty cycle processing where idle times can be exploited for energy savings. This paper implements a programmable power management where clock gating and dynamic voltage and frequency scaling (DVFS) are both configurable. Clock gating shuts off the clock to reduce dynamic power consumption of a task. A DVFS system reduces the performance enough for a task to meet a specified deadline, distributing the workload across the long idle times. To scale the voltage, a 3:2 topology switched-capacitor converter (SCC) was used. For frequency scaling, a ring oscillator that scales well within sub-threshold voltages was implemented. Finally, a low overhead programmable DVFS controller was designed. Using these blocks to implement DVFS, results show a 35-38% full system energy savings. Moreover, the active components where the programmable DVFS is applied to shows 52-59% energy savings.
Text Detection in Natural Scenes Based on Maximally Stable External Region and Deep Convolutional Network (2015)

In this paper, an effective scene text detection algorithm is proposed based on Maximally Stable External Region (MSER) and deep convolutional network. This algorithm is competitive with the best existing scheme widely used on benchmark International Conference on Document Analysis and Recognition (ICDAR) 2013. The main contribution of the paper lies in two aspects. Firstly, an efficient text/background classifier is designed on the basis of convolutional neural network, which outperforms the artificial design features. What's more, synthesis data is used for constructing the training set so as to avoid over-fitting; secondly, an analysis method based on MSER is presented to drop out the majority background patches and extract valid character areas. On the basis of analysing connected components, the size of candidate character is determined instead of the time-consuming scale scanning.
Percutaneous absorption of valproic acid and its plasma concentration after application of ointment. (1987)

In order to develop a percutaneous (p.c.) dosage form of valproic acid (VPA), ointments containing VPA and both VPA and its calcium salt (VPA-Ca) were prepared. The p.c. absorption was studied by determining the plasma concentrations of VPA in rabbits following application of either ointment. In addition, the in vitro penetration study with excised full-thickness rabbit skin was done to evaluate the pharmaceutical availability. VPA was readily and rapidly absorbed through the skin from the gel ointment. The plasma concentrations of VPA higher than 30 micrograms/ml were maintained for 6 h after application of 5% VPA.5% VPA-Ca gel ointment, and for 4 h after application of 5% VPA ointment. The bioavailability of VPA following dosing of both ointment was above 97%. The in vitro penetration rate through the skin and skin/solvent partition coefficient were significantly lower with 5% VPA.5% VPA-Ca solution than with 5% VPA, suggesting the slower penetration of VPA from the 5% VPA.5% VPA-Ca. A small difference was observed in the release rate of drugs from these ointments. The present results demonstrated the pharmaceutical effectiveness of the VPA.VPA-Ca ointment for seizure disorders.
Intravenous Lidocaine Does Not Improve Neurologic Outcomes after Cardiac Surgery (2019)

Intravenous lidocaine administered during and after cardiac surgery did not reduce postoperative cognitive decline at 6 weeks.
Cytofluorometric Identification of Plasmin-Sensitive Factor XIIIa Binding to Platelets (1988)

We have investigated the binding of blood coagulation factor XIIIa to thrombin-stimulated platelets using cytofluorometric analysis. Washed thrombin-stimulated platelets bound exogenously added factor XIIIa in a calcium-dependent reaction. The expression of endogenous platelet factor XIII was also detected on the surface of thrombin-stimulated platelets. When fluorescence analysis was performed based on particle size, factor XIIIa bound to the surface of greater than 95% of particles which contained more than one platelet, but only 50% of single platelets. The binding of factor XIIIa to thrombin-stimulated platelets was inhibited by plasmin. Plasmin also inhibited thrombin-dependent expression of the factor XIIIa binding site on platelets. Experiments in which thrombin-stimulated platelets were incubated with factor XIIIa in the presence of 125I-dimethylcasein or 3H-putrescine demonstrated that platelets bear both glutamyl and lysyl substrates for factor XIIIa. Thrombin increased the expression of factor XIIIa substrates by platelets. Plasmin inhibited both the expression of factor XIIIa substrates and degraded them. The binding of factor XIIIa to thrombin-stimulated platelets and the availability of factor XIIIa substrates on the platelet surface could provide a mechanism by which factor XIIIa stabilizes the hemostatic plug by promoting crosslinking reactions between platelet membrane proteins and adhesive glycoproteins. In contrast, plasmin inhibition of factor XIIIa binding and crosslinking could disrupt hemostasis.
Field experience with a digital relay for synchronous generators (1992)

The authors provide the specifications and characteristics of a digital relay for synchronous generators that performs seven protection functions. They also present preliminary performance results, following installation on one of the units at the Carillon generating station in the Hydro-Quebec power system. During a period of four months, although no fault was recorded in the unit, the relay watchdog system and self-monitoring routines functioned flawlessly. The prototype provides the basis for a new standard protection system for Hydro-Quebec's future and existing generating stations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Slow Intramural Heating With Diffused Laser Light (1999)

Slow, volumetric, and direct intramyocardial heating induces large, deep lesions without hazardous tissue damage. Such heating might cure postinfarction VT more successfully and safely than present techniques. Further testing and development of this method seem warranted.
Effect of Low Level laser Therapy and Pelvic Rocking Exercise in the Relief of Primary Dysmenorrhoea (2008)

This study was conducted to determine the effect of low level laser therapy (LLLT) and pelvic rocking exercise in reducing pain of primary dysmenorrhoea. Thirty volunteers virgin females complained of primary dysmenorrhoea engaged in this study. They were treated one day before menstruation and continued in the next two successive days of menstruation. They were evaluated by McGill Pain Questionnaire (MPQ) and estimation of serum cortisol level (SCL) before and after three months of treatment. The results revealed that LLLT and pelvic rocking exercise can alleviate pain during menstruation as there was a statistically significant reduction in pain and SCL after three months of treatment. It was concluded that LLLT and pelvic rocking exercise are effective and low cost methods for reducing dysmenorrheal pain.

Predictive Value of Robotic-Assisted Total Hip Arthroplasty (2015)

Acetabular cup positioning, leg-length discrepancy, and global offset are important parameters associated with outcomes following total hip arthroplasty (THA). Deviation from an accepted range of values can lead to significant complications, including dislocation, leg-length discrepancy, impingement, accelerated bearing surface wear, and revisions. The purpose of this study was to assess whether robotic-assisted THA was reliable in predicting radiographic measurements of cup inclination and anteversion, leg-length change, and global offset change. All 61 robotic-assisted THAs that met the inclusion and exclusion criteria were performed by a single surgeon through a mini-posterior approach. Data provided by the robot were collected prospectively, and radiographic data were collected retrospectively by 2 blinded independent reviewers. The cohort in this study consisted of 27 male and 34 female patients, with an average age of 60.5 years. A strong inter- and intraobserver correlation was found for the radiographic measurements of cup inclination, cup anteversion, leg-length discrepancy, and global offset (r>0.8 with P<.001 for all). Ninety-six point seven percent of robotic-measured inclination angles and 98.4% of robotic-measured anteversion angles were within 10° of radiographic measurements. One hundred percent of robotic-measured leg-length change and 91.8% of robotic-measured global offset change were within 10 mm of radiographic measurements. Robotic-assisted THA showed good predictive value for cup inclination and anteversion angles and measurements of leg-length change and global offset change done postoperatively on plain radiographs. Further refinement of the robotic system would make it more accurate in predicting the postoperative parameters mentioned.
Neuropathic Pain (2010)

Complex regional pain syndrome (CRPS) is a neuropathic pain condition that generally presents in an extremity usually following trauma. The diagnostic criteria originally proposed in 1994 and published by the IASP Press have been refined and subjected to validation studies. Dysfunction of the autonomic nervous system, once thought to be a key component of CRPS, is but one of several pathophysiologies. Much has been learned about the inflammatory and neurologic changes found in CRPS. Treatment is directed at the clinical disturbances. CRPS in children may be distinguished from the adult with subtle sensory differences and a larger behavioral disturbance.
Resistive Solenoid Development at the NHMFL (2010)

The National High Magnetic Field Laboratory (NHMFL) has several resistive solenoid magnet projects underway presently, including upgrade of four existing magnets, design of the conical bore insert for the Helmholtz Center Berlin (HZB), design of insert coils of the Series-Connected-Hybrid (SCH) for NHMFL and design of resistive split magnet. The upgrades and the design of the conical bore insert are discussed in detail while other programs are presented briefly.
Estimating Arterial Cyclic Strain from the Spacing of Endothelial Nuclei (2020)

Applying the new technique to areas around arterial branches could support or refute the hypothesis that the development of atherosclerosis is influenced by mural strain, and the method may be applicable to other tissues.
Proppant Flow Back Control for Fracturing Low Temperature Formations of Russia Methodology and Case Studies (2015)

Abstract Formations with a bottomhole static temperature below 70 degC are very common for quite a number of Russian oil provences such as Komi, Samara Area, Orenburg, Tatarstan Bashkiria, and Eastern Siberia. Many of these formations are now being developed with proppant fracturing which incorporates a lot of flow back issues due to the various reasons including high viscosity oil, aggressive TSO designs and cycle loads on a proppant pack due to ESP change regime. There are a number of solutions to prevent proppant flow back and the most common one is usage of resin- coated proppants. At temperatures below 70degC RCP needs chemical activation in order to achieve a solid proppant pack consolidation. Depending on temperature range and coating structure various types of activators can be used. Traditionally commercial activators were used at very high concentrations that may compromise proppant pack conductivity and performance fracturing fluid. Alternative techniques are based on using fiber technologies and unconventionally shaped proppants. The majority of flowback control techniques have been tested in Volga-Urals region of Russia, Orenburg, Samara and Bashkiria areas. Novel additives that accelerate curing, RCP was successfully implemented and pumped during hydraulic fracturing on the most oil fields of Samara area. Flow back problems were observed only at extremely low temperature reservoir (&amp;lt;30 degrees Celcius) with high- viscous (∼100+ cP) oil. Paper uncovers the details of activation process with detailed laboratory investigation for several RCPs and activators, proposes decision matrix for low temperature flow back control techniques, its applicability and design.
The prevention of type 2 diabetes mellitus: recent advances (2004)

Diabetes is a major public health problem that is approaching epidemic proportions globally. There is an urgent need for strategies to curb the rising prevalence of this disease, and prevention appears a logical approach. Lifestyle modifications with weight loss and moderate exercise can reduce the incidence of diabetes by >50% in patients with impaired glucose tolerance (IGT). The use of metformin, acarbose and other agents have been shown in randomized prospective trials to prevent type 2 diabetes in high-risk subjects with IGT. Other pharmacological interventions are currently being examined in large prospective studies. It is likely that one or a combination of these approaches could make diabetes prevention a reality in the near future.
Tunable Reaction Potentials in Open Framework Nanoparticle Battery Electrodes for Grid-Scale Energy Storage (2012)

The electrical energy grid has a growing need for energy storage to address short-term transients, frequency regulation, and load leveling. Though electrochemical energy storage devices such as batteries offer an attractive solution, current commercial battery technology cannot provide adequate power, and cycle life, and energy efficiency at a sufficiently low cost. Copper hexacyanoferrate and nickel hexacyanoferrate, two open framework materials with the Prussian Blue structure, were recently shown to offer ultralong cycle life and high-rate performance when operated as battery electrodes in safe, inexpensive aqueous sodium ion and potassium ion electrolytes. In this report, we demonstrate that the reaction potential of copper-nickel alloy hexacyanoferrate nanoparticles may be tuned by controlling the ratio of copper to nickel in these materials. X-ray diffraction, TEM energy dispersive X-ray spectroscopy, and galvanostatic electrochemical cycling of copper-nickel hexacyanoferrate reveal that copper and nickel form a fully miscible solution at particular sites in the framework without perturbing the structure. This allows copper-nickel hexacyanoferrate to reversibly intercalate sodium and potassium ions for over 2000 cycles with capacity retentions of 100% and 91%, respectively. The ability to precisely tune the reaction potential of copper-nickel hexacyanoferrate without sacrificing cycle life will allow the development of full cells that utilize the entire electrochemical stability window of aqueous sodium and potassium ion electrolytes.
Q-Learning for energy balancing and avoiding the void hole routing protocol in underwater sensor networks (2018)

In energy constraint networks, the utilization of limited node battery is very crucial to enhance the network lifespan. The imbalanced node battery dissipation greatly effects the performance of the network. In this paper, we propose QLearning based energy-efficient and balanced data gathering routing protocol (QL-EEBDG). The effectiveness of a forwarder node is computed based on; residual energy of the source node and group energies of the neighbour nodes. The consideration of energy parameters provides complete control on the forwarder node selection and ensures efficient energy consumptions in the network. Still, due to topology changes, void node occurs which is avoided through adjacent node technique (QL-EEBDG-ADN). This scheme finds an alternate route via neighbor nodes to provide continuous communication among the network nodes. Simulations are performed to validate the effectiveness of proposed schemes against existing scheme based on energy tax, network lifetime.
A Validated Biorepository of Retina and Choroid Tissues for Gene Expression Studies (2014)

Research studies on pathologies affecting the posterior segment of the eye are usually carried out either in animal models or cell lines of human origin that mimic the molecular patterns occurring in the human retina-pigment epithelium-choroid (RPC) complex in vivo. As this is not always the case, we were prompted to validate a biorepository of RPC tissues for research purposes. A PubMed literature search on "retina," "choroid," "bio-bank," or "biorepository" as keywords did not lead to any publication describing the collection and banking of samples from the RPC complex for research purposes. The possibility to obtain access to a validated collection of high quality human RPC tissues as starting material is likely to lead to more appropriate findings and treatments, which eventually may improve human ocular health. Here we show that when tissues are harvested (T <25 hours from donor death) and stored appropriately, RNAs are not degraded (RNA Integrity Number Values >8.0) and express specific genes and molecular/biochemical pathways occurring in the RPC complex. These quality controlled tissues/RNAs comprising the biorepository could therefore be used for gene expression studies by research scientists and clinicians interested in testing their hypotheses in a more appropriate setting, thus replacing studies performed on less relevant animal models and cells in vitro, and directly extrapolating the findings to human pathophysiology.

Preparation of Tl2Ba2Ca2Cu3Oy Thick Films from Ba-Ca-Cu-O Films (1988)

The preparation of Tl 2 Ba 2 Ca 2 Cu 3 O y thick films from spin-coated Ba-Ca-Cu-O films in the presence of thallium oxide vapor was studied. The starting Ba-Ca-Cu-O films were prepared by pyrolysis of organic acid salts. The preparation of the Tl 2 Ba 2 Ca 2 Cu 3 O y thick films was carried out for cases of the presence of Tl 2 O 3 powder and of mixed powders of Tl 2 O 3 , BaO 2 , CaO 2 and CuO. A Tl 2 Ba 2 Ca 2 Cu 3 O y film with T c onset =126 K, T c mid =115 K and T c zero =108 K was obtained. Control of the thallium content of the films was more easily accomplished when using the mixed powders of Tl 2 O 3 , BaO 2 , CaO 2 and CuO than when using Tl 2 O 3 powder alone.
Syntheses of 5-Formyl- and 5-Carboxyl-dC Containing DNA Oligos as Potential Oxidation Products of 5-Hydroxymethylcytosine in DNA (2011)

To investigate the potential oxidation products of 5-hydroxymethylcytosine (5-hmC)-containing DNA, we present here efficient syntheses of 5-formyl- and 5-methoxycarbonyl-2'-deoxycytidine phosphoramidites. The 5-formyl group in III was easy to introduce and was compatible with phosphoramidite and DNA syntheses. An additional treatment of ODN1 with NaBH(4) produced the corresponding ODN2 quantitatively. Phosphoramidite V was also incorporated into DNA, and the methyl ester could be hydrolyzed under mild basic conditions to afford ODN3.
Optimism, coping, psychological distress, and high-risk sexual behavior among men at risk for acquired immunodeficiency syndrome (AIDS). (1992)

In a cohort of gay men responding to the threat of acquired immunodeficiency syndrome (AIDS), dispositional optimism was associated with less distress, less avoidant coping, positive attitudes as a coping strategy, and fewer AIDS-related concerns. Men who knew they were seropositive for human immunodeficiency virus (HIV) were significantly more optimistic about not developing AIDS than men who knew they were seronegative for HIV. This AIDS-specific optimism was related to higher perceived control over AIDS and to active coping among seropositive men only and to health behaviors in both serostatus groups. There was no relation of optimism to risk-related sexual behavior. It is concluded that optimism is psychologically adaptive without necessarily compromising health behavior. It is also concluded that it is useful to distinguish between event-based optimistic expectations and dispositional optimism.
Acute Renal Failure due to Bacterial Pyelonephritis (1979)

Five patients who presented with acute renal failure in association with urinary tract infection are reported. Renal function improved rapidly on antibacterial therapy and no alternative cause for acute renal failure could be identified. None had previously been known to have renal disease but three of the five had taken considerable amounts of analgesics. The unusual severity of renal functional impairment resulting from urinary tract infection in these patients is unexplained but may relate to previous analgesic abuse and/or delay in treatment. Since acute non-obstructive pyelonephritis may result in severe reversible renal failure, this diagnosis must be considered in patients presenting with acute uraemia.
Thermo/structural design considerations to achieve the Large Space Telescope line-of-sight requirements (1975)

The Large Space Telescope (LST) which is scheduled for launch in 1982, is a long-life, precision-pointing, earth-orbiting satellite requiring a structural system that provides high dimensional stability, minimum thermal distortion, and minimum response to onboard dynamic environments (e.g., reaction wheels). The results of a detailed thermostructural finite element computer analysis show that the telescope structure, even though fabricated from a material with a zero coefficient of thermal expansion, must be isolated from the external structure by a three-point support (flex joints or spherical bearings will accomplish this). Other thermo/structural analysis of the metering structure showed that second-order deformations have a significant effect on the alignment of the primary and secondary mirrors.
