Methods for Measurement of Energy Consumption in Mobile Devices (2013)

Abstract Mobile devices have become an integral part of our life and provide dozens of useful services to their users. However, usability of mobile devices is hindered by battery lifetime. Energy conservation can extend battery lifetime, however, any energy management policy requires accurate prediction of energy consumption, which is impossible without reliable energy measurement and estimation methods and tools. We present an analysis of the energy measurement methodologies and describe the implementations of the internal (profiling) software (proprietary, custom) and external software-based (Java API, Sensor API, GSM AT) energy measurement methodologies. The methods are applied to measure energy consumption on a variety of mobile devices (laptop PC, PDA, smart phone). A case study of measuring energy consumption on a mobile computer using 3DMark06 benchmarking software is presented

The palpable nodule of prostatic cancer. Results 15 years after radical excision (1968)

Until Jan 1, 1951, radical perineal prostatectomy was performed on 111 patients with clinically localized and discrete cancer. Of these, 103 patients were followed for 15 years or longer. No patient with high-grade cancer or with cancer extending microscopically beyond the prostate survived without recurrence. Of 86 patients with locally limited cancer, 28 lived 15 years free of the disease (33%). This represents twice the success rate achieved with endocrine treatment of patients with what was thought to be comparable conditions. One patient died in the hospital. Complications were infrequent, minor, and temporary. In 82 recent cases an improved technique has provided complete urinary control in 80 instances.
Computed Departure Curves For The Thermal Neutron Decay Time Log (1975)

The Thermal Neutron Decay Time (TDT) Log has become an important tool for formation evaluation in cased holes. For accurate interpretation of this log, it is necessary to know how to correct for borehole effects and for the effect of spatial diffusion of thermal neutrons. Some experimental measurements of tool response have been made in laboratory formations. However, these are limited as to the cases that can be handled, and they are very time-consuming. Furthermore, for the many situations that arise in logging practice, results are needed for a wide range of formation porosities, formation salinities, hole sizes, casing sizes, and borehole salinities. For this reason, a computer program has been developed to calculate tool response under various conditions. The nature of the program and its uses and limitations are described. Some indications of its use are also given. Illustrative computed departure curves are shown for the TDT-K tool, which is in wide use at the present time. A log example is shown. (auth)
In vitro Replication of Scrapie Agent in a Neuronal Model: Infection of PC12 Cells (1984)

A rat phaeochromocytoma cell line, termed PC12, was used to study scrapie replication. These cells, in response to the addition of nerve growth factor (NGF), exhibit a number of neuronal properties including morphological differentiation, electrophysiological responsiveness, and neurotransmitter synthesis. Cultures were exposed to scrapie brain homogenate (strain 139A), harvested every week for up to 6 weeks, and assayed for scrapie infectivity. Scrapie replication in vitro was monitored by injecting scrapie agent-exposed NGF-treated PC12 cells into mice and measuring time intervals from injection to onset of clinical symptoms. Mouse incubation periods vary inversely with the amount of scrapie infectivity present. Cells harvested at 7 and 14 days after exposure to scrapie agent showed a decrease in the level of infectivity followed by an increase at subsequent time points. The increase in scrapie infectivity from early to late time intervals after agent exposure clearly indicated replication in vitro. A fusion agent was not necessary to establish infection, and the addition of mouse peritoneal macrophages caused a reduction in the yield of infectivity per culture. Examination of cells by phase-contrast microscopy failed to reveal any cytopathology.

A Novel Top-K Automobiles Probabilistic Recommendation Model Using User Preference and User Community (2014)

The economic level rising and the rapid development of automobile industry offers various opinions for buyers. The automobile dealers provide services to users by recommending popular and fashionable automobiles. However, few of them offer the personalized recommendation services online. In this paper, we propose an automobile recommendation system to recommend top-K ranked automobiles for users. We first propose a model to analyze the individual requirements and user community which may affect the user's purchase behaviors. And then we develop an estimation algorithm to compute the parameters in proposed model. With the trained model, we conduct the personalized recommendation algorithm using model parameters. Experiments with real-life data sets confirms the effectiveness and scalability of our algorithms.
A Control Circuit With Load-Current Injection for Single-Phase Power-Factor-Correction Rectifiers (2007)

A load-current-injection control technique for boost-derived power-factor-correction (PFC) rectifiers with average current-mode control is proposed in this paper. By adding a load-current loop to the conventional inductor current loop, the output voltage response to load steps is speeded up, almost eliminating the typical voltage overshoots of this kind of converters. Although the techniques based on the load-current injection are traditionally called "load feedforward," this paper shows that an additional feedback loop, which modifies the linear small-signal model of the converter, is also introduced. In order to validate the concept, a converter prototype working from a universal input line has been designed and tested, showing that a very fast dynamic response of PFC rectifiers may be achieved in a cost-effective way
Chitin Synthesis as a Target for Antifungal Drugs (2003)

Human mycoses have become a threat to health world-wide. Unfortunately there are only a limited number of antimycotic drugs in use. Promising targets for drugs specific against fungi are those affecting chitin synthesis. Chitin is absent in vertebrates, and is essential for fungal wall integrity. A thorough knowledge of the mechanism of chitin synthesis is required to design specific inhibitors. We review here our current understanding of the process, and the most promising drugs that inhibit it. Chitin is made by chitin synthases requiring specific microvesicles, the chitosomes, for intracellular transport. Fungi contain several chitin synthases, some of which may be essential at a certain stage. This phenomenon is important to take into account for drug design. The most widely studied chitin synthase inhibitors are polyoxins and nikkomycins that probably bind to the catalytic site of chitin synthases. These are not equally susceptible to the drugs. In Saccharomyces cerevisiae the order of sensitivity is: Chs3p>Chs1p>Chs2p. Main problems for their succesful use in vivo are: low permeability, and different susceptibility of fungal species, and variable responses in animal models. Chemical modifications have been proposed to make more potent derivatives. Other synthetic or natural compounds are also promising as possible inhibitors, but their properties are less well known. Rational drug design has proceeded only on the basis of existing inhibitors, because the structure of the active site of chitin synthase is unknown. Undoubtedly, determination of this, and the biosynthetic mechanism will reveal unexpected drug targets in the future.
Uses of turmeric in dentistry: An update (2009)

Turmeric has been used for thousands of years as a dye, a flavoring, and a medicinal herb. In India, it has been used traditionally as a remedy for stomach and liver ailments, as well as topically to heal sores. Ancient Indian medicine has touted turmeric as an herb with the ability to provide glow and luster to the skin as well as vigor and vitality to the entire body. Since turmeric has antimicrobial, antioxidant, astringent, and other useful properties, it is quite useful in Dentistry also. The objective of this article is to highlight various uses of turmeric in the dental field along with its use in medical problems.
Production of modified clays and their use in polypropylene‐based nanocomposites (2012)

Abstract The use of modified bentonite as a reinforcement in polypropylene (PP)/organoclay/maleic anhydride grafted polypropylene (MAPP) nanocomposites was investigated. The modified bentonites (organoclays) were prepared from raw (unpurified) bentonite (RB) and two quaternary ammonium salts with long alkyl tails: hexadecyl trimethyl ammonium bromide [HDA][Br] and tetrakisdecyl ammonium bromide [TKA][Br]. The ternary composites were produced by using a corotating twin screw extruder, followed by injection molding, and they exhibited microcomposite structure as observed by XRD. In order to observe the effects of purification of the bentonite, purified bentonite (PB) was obtained through sedimentation of raw bentonite, and later modified with two quaternary ammonium salts: dimethyl dioctadecylammonium chloride [DMDA][Cl] and [TKA][Br], and one quaternary phosphonium salt: tributyl hexadecyl phosphonium bromide [TBHP][Br]. Ternary nanocomposites (PP/organoclay/MAPP) with these organoclays were produced by using a corotating twin screw extruder, followed by batch mixing in an intensive batch mixer, and by injection molding. The use of [DMDA][Cl] and [TBHP][Br] resulted in nanocomposite formation, whereas the use of [TKA][Br] resulted in microcomposite formation as observed by XRD and TEM. Young's modulus of PP was increased by 30% with DMDA and 9% with TBHP. The yield strength of PP was increased by 15% with DMDA and 8.3% with TBHP. © 2012 Wiley Periodicals, Inc. J. Appl. Polym.

Assessment and validation of a defined fluid restriction protocol in the use of subcutaneous desmopressin for children with inherited bleeding disorders (2016)

Subcutaneous desmopressin was well-tolerated, with no serious side-effects observed, and good biological responses in preoperative trials. A two-thirds maintenance fluid regimen was effective at preventing symptomatic hyponatremia in our cohort, and is now the standard protocol for fluid restriction post-DDAVP administration in our centre.
Spatial Data Resource Index in Grid Environment (2009)

Grid is a promise technology which could easily share distributed heterogeneous computing resources. It brings together geographically and organizationally dispersed computational resources. This paper presented a framework that aggregated the spatial resources based on grid technology, OGC specification and spatial data index. First, a grid environment for sharing geospatial data resources was setup by GlobusToolkits(GT); an effective architecture was designed for managing spatial data in a grid environment. Secondly all the geospatial resource was described by geographic markup language (GML), which could describe the metadata of heterogeneous data effectively. And with monitor and discovery service (MDS), a service discovery framework was implemented, with the framework; all the grid services encapsulated with the Web service resource framework (WSRF) could be easily discovered. Then with calling these services, the spatial data could be easily discovered. A spatial data index was also built up by R-tree for access of data more effectively. We implemented the spatial data discovery framework and experiments indicated that spatial data could be easily discovered in the grid environment effectively and reliably.

A case‐control study of Alzheimer's disease in China (1992)

We conducted a case-control study to assess possible factors associated with Alzheimer's disease (AD) with 70 clinically diagnosed AD patients and 140 age- and sex-matched nondemented neighborhood controls in China. Factors significantly associated with AD cases were family history of dementia in first-degree relatives, family history of psychotic disorders in first-degree relatives, and left-handedness/ambidexterity. A history of arthritis showed a significantly negative association with AD. Neither a family history for Down's syndrome, history of head trauma, nor other conditions that might support immune or viral hypotheses in AD were significantly associated with AD cases. These data support the role of familial/genetic factors in AD.
Gas Turbine Cogeneration in the Australian Economic Environment (1993)

The viability of a cogeneration project is affected by a number of factors. A model has been developed to analyse the economics of retrofitting cogeneration to sites with suitable heat and power demands. The model compares the cost of operating the gas turbine cogeneration plant with the cost of generating the heat in gas fired package boilers and purchasing the electricity from the local Council, and calculates a simple payback period for the cogeneration unit. The model allows optimisation of the electrical size, the heat to power ratio and the operating hours of a gas turbine powered cogeneration installation so as to minimise the payback period. The optimum arrangement depends on the buyback arrangements available for surplus electricity, and for different buyback prices there are widely different solutions. Once the situation has been optimised, the model allows easy sensitivity analysis of the other variables involved. This analysis shows that the payback period is sensitive to buyback rates, electricity prices and gas prices, in that order.
Heuristic Intrusion Detection and Prevention System (2015)

The Heuristic Intrusion Detection and Prevention System (HIDPS) is a system that can intelligently scan for malicious behavior from a program either within the system, or trying to access the system. The aforementioned system contains no `Virus definitions' as such but works “Intelligently” using heuristics and online scanning techniques. The proposed system will be able to analyze the program and make decisions about its nature i.e. malicious or non-malicious. Depending upon the nature of the program access is granted or revoked. The system does not rely on time to time updates or any kind of updates at all, reason being the use of heuristics and online scanning techniques. It functions as a standalone script which can be a complete security suite in itself. Since every active process and network packet is monitored, the possibility of rootkits or Trojans remaining undetected is small.
Penetration of electromagnetic fields of an open-ended coaxial probe between 1 MHz and 1 GHz in dielectric skin measurements (1999)

An open-ended coaxial probe is often used for investigating the dielectric properties of biological tissues. The present study indicates that in addition to the probe size, the penetration of the electromagnetic (EM) fields of an open-ended coaxial probe in contact with the skin is dependent on the applied frequency between 1 MHz and 1 GHz. At high frequencies, above 100 MHz, the measured dielectric parameters are functions of the dielectric properties of different cutaneous layers and subcutaneous fat. At lower frequencies, less than 10 MHz, the measurement is mainly dependent on the dielectric properties of superficial structures of the skin. The reason for this is that the probe, the surface of the skin, mainly stratum corneum, and underlying skin form a capacitance where the stratum corneum with low water content lies between the well-conducting dermis and the probe. The situation is equivalent to the frequency-dependent Maxwell-Wagner interfacial polarization. This result is verified by experimental dielectric measurements and with human skin in vivo.
A novel method for stochastic nonlinearity analysis of a CMOS pipeline ADC (2001)

An analytic appraoch is presented for estimating the nonlinearity of an analog to digital converter (ADC) as a function of the variations in the circuit devices. The approach is demonstrated for the case of a pipeline ADC with digital error correction. Under some mild assumptions on the expected variations, the error probability is expressed as a simple explicit function of the standard deviations in the components' parameters: gain errors, comparator offset errors and resistor errors. The analytical expression is verified for Integral Non Linearity (INL), and its limits are studied using Monte-Carlo simulations of a 10 bit pipeline ADC structure.
A Review of the Properties and Applications of Poly (Methyl Methacrylate) (PMMA) (2015)

Advances in the use of poly (methyl methacrylate) (PMMA) have opened up a wide range of applications in the field of nanotechnology. The knowledge of the properties of PMMA has contributed a lot to the recent boosts in the synthesis, modification, and applications of the polymer. However, there is a need to condense these developments in the form of an article for better understanding and easy access. This review highlights the fundamental physical properties of PMMA, coupled with experimental evidence of its essential chemistry, such as solubility, hydrolysis, grafting, combustion reactions, reactions with amines, and thermal decomposition. The recent developments in the applications of PMMA in biomedical, optical, solar, sensors, battery electrolytes, nanotechnology, viscosity, pneumatic actuation, molecular separations, and polymer conductivity were also revealed.
Rhabdomyolysis: a review of the literature. (2009)

Rhabdomyolysis is a potentially life-threatening syndrome that can develop from a variety of causes; the classic findings of muscular aches, weakness and tea-coloured urine are non-specific and may not always be present. The diagnosis therefore rests upon the presence of a high level of suspicion of any abnormal laboratory values in the mind of the treating physician. An elevated plasma creatine kinase (CK) level is the most sensitive laboratory finding pertaining to muscle injury; whereas hyperkalaemia, acute renal failure and compartment syndrome represent the major life-threatening complications. The management of the condition includes prompt and aggressive fluid resuscitation, elimination of the causative agents and treatment and prevention of any complications that may ensue. The objective of this review is to describe the aetiological spectrum and pathophysiology of rhabdomyolysis, the clinical and biological consequences of this syndrome and to provide an appraisal of the current data available in order to facilitate the prevention, early diagnosis and prompt management of this condition.
The effects of a thyroid hormone analog on left ventricular performance and contractile and calcium cycling proteins in the baboon. (1997)

To determine the biochemical and related functional effects of the thyroid analog diiodothyroproprionic acid (DITPA) on primate myocardium, we examined, both before and after 23 days of DITPA (3.75 mg/kg): myosin heavy-chain (MHC) isoforms and sarcoplasmic reticulum (SR) calcium cycling proteins; left ventricular (LV) function; and the LV force-frequency relation in four baboons chronically instrumented with sonomicrometers and micromanometers. The force-frequency relation was measured as the response of isovolumic contraction (dP/dtmax) to incremental pacing and the critical heart rate (HRcrit) as the rate at which dP/dtmax reached its maximum. DITPA increased basal LV dPt/dtmax (3,300 +/- 378 versus 2,943 +/- 413 mm Hg/sec; p = .09), and velocity of circumferential shortening (1.13 +/- 0.30 versus 0.76 +/- 0.30 circ/sec; p < .01), decreased the basal time constant of isovolumic relaxation (24.2 +/- 1.6 versus 29.9 +/- 2.5 msec; p < .05), and increased the HRcrit (203 +/- 19 versus 168 +/- 20 bpm; p < .05), without effecting significant changes in either basal heart rate (119 +/- 14 versus 111 +/- 17 bpm) or systolic blood pressure (137 +/- 14 versus 126 +/- 8 mm Hg). Quantitative immunoblotting revealed significant decreases in both phospholamban and the ratio of phospholamban to SR Ca2+ adenosine triphosphatase in DITPA-treated animals when compared to four untreated controls. By contrast, alpha-MHC isoform was undetectable in both DITPA treated and control baboons. Thus, DITPA favorably alters the stoichiometry between the SR calcium pump and its inhibitor, phospholamban, and has positive inotropic and lusitropic effects in the normal primate left ventricle, which may be useful in the treatment of heart failure. Unlike thyroid hormone, these changes occur in the absence of detectable alpha-MHC isoform protein expression and without an increase in heart rate.
Performance of an Instrumented Slope Covered by a Capillary Barrier System (2011)

A capillary barrier as a cover system is a two-layer system of distinct hydraulic properties to prevent water infiltration into the underlying soil by utilizing unsaturated soil mechanics principles. This paper illustrates the application of the capillary barrier system on a slope that experienced shallow slip failures to prevent future rainfall-induced slope failures. In this study, the capillary barrier system was designed as a cover system for residual soil slopes with a steep slope angle under heavy rainfall conditions of the tropics. The capillary barrier system was constructed using fine sand as the fine-grained layer and granite chips as the coarse-grained layer. Both layers were contained in a cellular confinement system. The slope was instrumented with tensiometers and piezometers. The tensiometers were installed at different depths from about 0.5 m to 2.0 m below the slope surface. An adjacent original slope without the capillary barrier system was also instrumented using tensiometers to investigate the performance and effectiveness of the capillary barrier system in reducing rainwater infiltration and maintaining negative pore-water pressure in the slope. The detailed installation of a matric suction measurement device is discussed comprehensively in this paper. The measurement results showed that the capillary barrier system was effective in maintaining the negative pore-water pressures during rainfalls, particularly on the crest of the slope.
