Determining Distribution Power System Loading Measurements Accuracy Using Fuzzy Logic (2016)

This paper presents a fuzzy logic method and experimental investigation to determine distribution power systems loading measurements accuracy. The method is applied on loading measurements associated with a real South African power systems network, and includes manufacturing supply loading measurements. The results show fuzzy logic as an efficient strategy in determining loading data accuracy in comparison to a traditional approach of manually human analysis. The method is less time consuming relative to the traditional method of going through the data manually. The paper further illustrates that the approach can be applied in manufacturing plants' power systems distribution networks.
Bovine spongiform encephalopathy: epidemiological studies. (1988)

This study, initiated in June 1987, describes the epidemiology of bovine spongiform encephalopathy (BSE), a recently described novel neurological disease of domestic cattle first identified in Great Britain in November 1986. Records suggested that the earliest suspected cases occurred in April 1985. There was variability in the presenting signs and the disease course, but the majority of cases developed behavioural disorders, gait ataxia, paresis and loss of bodyweight; pruritus was not a predominant sign. The form of the epidemic was typical of an extended common source in which all affected animals were index cases. The use of therapeutic or agricultural chemicals on affected farms presented no common factors. Specific genetic analyses eliminated BSE from being exclusively determined by simple mendelian inheritance. Neither was there any evidence that it was introduced into Great Britain by imported cattle or semen. The study supports previous evidence of aetiological similarities between BSE and scrapie of sheep. The findings were consistent with exposure of cattle to a scrapie-like agent, via cattle feedstuffs containing ruminant-derived protein. It is suggested that exposure began in 1981/82 and that the majority of affected animals became infected in calfhood.
Reducing Radiation Risk in Orthopaedic Trauma Surgery (2011)

Summary Fluoroscopy is considered indispensible during contemporary orthopaedic trauma surgery. However, there is increasing concern regarding occupational safety in the operating room (OR). During the course of a career, the orthopaedic surgeon and OR staff could be exposed to potentially dangerous levels of radiation. This exposure can cause substantial cytogenetic and chromosomal damage, potentially increasing cancer risk. The literature does not clearly identify a safe threshold for radiation exposure. Even relatively small doses should be considered dangerous over the long-term. Therefore, it is accepted that annual exposure should be kept to an absolute minimum. Established protective measures include observance of safe working distance from the radiation source and the routine use of protective garments. In addition, promising computerized technologies may support improved surgical precision while significantly reducing dependence on intraoperative fluoroscopy.
The Road to Multi-Dimensional Bit-by-Bit Optical Data Storage (2010)

Recent advances in optical data storage have led to the development of a 5-D device that could hold up to 2,000 times more data than a conventional DVD. These authors discuss this and other milestones on the road to multi-dimensional optical memory with petabyte capacity.
Coincident sequencing for fingerprint verification (2002)

A high-speed and low-cost system for scanning, identifying and encoding fingerprints is described. The system uses a technique called coincident sequencing for the positive identification of individuals using fingerprint characteristics without the necessity to store any fingerprint images. Work to improve the input image by refinement of the scanner and the cleaning process is continuing. As the cleaning process consists of filtering, thinning, and chain coding, improvements and updates on all three stages are constantly being made. It is expected that significantly less than 1% false reject and 0% false accept error rates can and will be achieved.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Drug-induced liver disease 2004 (2005)

Purpose of review To summarize the salient reviews, studies and case reports and series that dealt with clinical, pathological, methodological, and epidemiological descriptions of drug-induced liver disease in the calendar year 2004. Recent findings While no new causes of drug-induced liver injury were reported for 2004, several new reports of previously recognized hepatotoxins, including herbal products, were published. These include the antiretroviral drugs for HIV and agents to manage tuberculosis. Acetaminophen (APAP) retained its preeminent position as the leading cause of drug-induced acute liver failure, currently accounting for nearly 50% of cases according to the latest figures from the U.S. Acute Liver Failure Study Group. Not surprisingly, APAP also heads the list of drugs and toxins leading to liver transplantation for acute hepatic failure. Efforts to reduce the number of cases of intentional APAP poisonings by restricting the number of tablets sold at any one time in the UK are ongoing, but the success of the program may be lessening, as was pointed out this year. The use of potentially hepatotoxic medications in patients with underlying liver disease was examined with the statins, and they emerged as a safe class for use in this setting. Summary Given the apparent increasing incidence of acute liver failure attributable to APAP in the US, additional efforts are still needed to better define the risks associated with its use and to further reduce the incidence of severe liver injury from this widely used agent.
FDTD design of a Chinese hat feed for shallow mm-wave reflector antennas (2002)

Rotationally symmetric reflectors with hat feeds are attractive for radio link applications the mm-wave band due to their low sidelobes, simple rotationally symmetric structure and low manufacture cost. The standard hat feed has its best performance in a very deep reflector. In this paper, the V2D computer code based on the finite-difference time-domain (FDTD) method is applied to the analysis of a Chinese hat feed, which is optimized for use in a more shallow reflector. The FDTD results have been post processed to obtain the different subefficiencies characterizing spillover, polarization, illumination and phase losses.
Healos and Bone Marrow Aspirate Used for Lumbar Spine Fusion (2006)

The null hypothesis is only partially correct. Healos and BMA are not inferior to autologous iliac crest bone as a graft material in posterolateral lumbar spine fusions but are radiographically ineffective in lumbar interbody fusions.
Perinatal and childhood risk factors for inflammatory bowel disease: a case-control study. (1995)

These data contradict reports from a recent study in central Sweden, but relatively early exposure to measles in childhood may still be a risk factor for the development of Crohn's disease.
Risk of pulp damage due to temperature increase during thermodebonding of ceramic brackets (1997)

The purpose of this study was to perform in vitro measurements of the temperature increase at the enamel-dentine interface during electrothermal removal of ceramic brackets, and to analyse, in vivo, whether signs of pulp damage can be observed 4 weeks after the procedure. In vitro study: a total of 29 caries-free human teeth were cut into buccal and lingual halves. The buccal halves were bonded with ceramic brackets, and miniature thermocouples were placed from the pulpal side into holes drilled to the enamel-dentine interface under the centre of the bracket slot. From the onset of thermodebonding, the temperature increase relative to room temperature was recorded for a period of 43 seconds. The maximum temperature increase at the enamel-dentine interface was 6.9 degrees C. In vivo study: a total of 12 human premolars scheduled for extraction for orthodontic reasons were bonded with ceramic brackets. Electrothermal debonding was performed the following day. After 4 weeks, the teeth were extracted and prepared for histological examination. Following demineralization, sections were prepared for light microscopic examination. No signs of pulpal inflammation were observed.
Perspective on the Martini model (2013)

The Martini model, a coarse-grained force field for biomolecular simulations, has found a broad range of applications since its release a decade ago. Based on a building block principle, the model combines speed and versatility while maintaining chemical specificity. Here we review the current state of the model. We describe recent highlights as well as shortcomings, and our ideas on the further development of the model.
Endogenous Voltage Potentials and the Microenvironment: Bioelectric Signals that Reveal, Induce and Normalize Cancer (2014)

Cancer may be a disease of geometry: a misregulation of the field of information that orchestrates individual cells' activities towards normal anatomy. Recent work identified molecular mechanisms underlying a novel system of developmental control: bioelectric gradients. Endogenous spatio-temporal differences in resting potential of non-neural cells provide instructive cues for cell regulation and complex patterning during embryogenesis and regeneration. It is now appreciated that these cues are an important layer of the dysregulation of cell: cell interactions that leads to cancer. Abnormal depolarization of resting potential (V<sub>mem</sub>) is a convenient marker for neoplasia and activates a metastatic phenotype in genetically-normal cells <i>in vivo</i>. Moreover, oncogene expression depolarizes cells that form tumor-like structures, but is unable to form tumors if this depolarization is artificially prevented by misexpression of hyperpolarizing ion channels. V<sub>mem</sub> triggers metastatic behaviors at considerable distance, mediated by transcriptional and epigenetic effects of electrically-modulated flows of serotonin and butyrate. While <i>in vivo</i> data on voltages in carcinogenesis comes mainly from the amphibian model, unbiased genetic screens and network profiling in rodents and human tissues reveal several ion channel proteins as bona fide oncogene and promising targets for cancer drug development. However, we propose that a focus on specific channel genes is just the tip of the iceberg. Bioelectric state is determined by post-translational gating of ion channels, not only from genetically-specified complements of ion translocators. A better model is a statistical dynamics view of spatial V<sub>mem</sub> gradients. Cancer may not originate at the single cell level, since gap junctional coupling results in multi-cellular physiological networks with multiple stable attractors in bioelectrical state space. New medical applications await a detailed understanding of the mechanisms by which organ target morphology stored in real-time patterns of ion flows is perceived or mis-perceived by cells. Mastery of somatic voltage gradients will lead to cancer normalization or rebooting strategies, such as those that occur in regenerating and embryonic organs, resulting in transformative advances in basic biology and oncology.
Acupuncture Points of the Cervical Plexus (1984)

Acupuncture points in the neck region are basically distributed along the terminal branches of the cervical plexus. There are two components of the plexus, cutaneous and muscular. The cutaneous component of the cervical plexus consists of four major branches which are the lesser occipital, great auricular, transverse cervical, and supraclavicular nerves. Practically all of the acupuncture points in the neck are found along the routes of these cutaneous nerves. It is suggested that acupuncture points in this region be names according to the anatomical designation of these nerves.
Performance comparison of index structures for multi-key retrieval (1984)

In this paper, we report on a performance comparison of four software implemented index structures for multi-key retrieval the inverted file, the grid file and two variants of multidimensional B-trees It turns out that the recently suggested structures multidimensional B-tree and grid file outperform the traditional inverted file
Drive-level capacitance profiling: Its application to determining gap state densities in hydrogenated amorphous silicon films (1985)

We have developed a new method of capacitance profiling which is greatly superior to standard profiling techniques for materials like amorphous silicon that contain high densities of deep gap states. This technique, which makes use of the variation of the junction capacitance with the alternating voltage amplitude, is largely immune to the effects of surface states and is readily interpreted in terms of a simple integral over the density of states, g(E). This method is applicable to both doped and semi-insulating undoped samples.
Clinical studies with matrix metalloproteinase inhibitors (1999)

Matrix metalloproteinases (MMPs) have been implicated in the invasive growth and spread of tumours. Potent and selective inhibitors of MMPs have been synthesized. These inhibitors can prevent tumour invasion in vitro and have suppressed tumour growth and metastasis in animal cancer models. Several MMP inhibitors have now reached clinical trials. Phase I studies indicate that the inhibitors can be given by mouth and that over the short term they are well tolerated. Longer, randomised studies in cancer patients are now underway.
MPRINT: VAX printing made simple (1994)

Users with stand-alone personal computers and personal printers usually find printing simple, but on a VAX computer or VAX cluster there may be many printers of different types located in different areas. The print queues set up for these printers may require different form qualifiers and may not all be able to print all documents. This article describes the basic steps a VAX system manager should take in setting up and managing print queues on a VAX and tells how to access these queues from a VAX, Unix, Macintosh, or DOS Computer. It gives a basic overview, but includes several helpful items that are obscure or completely undocumented. Following this overview, there is a description of a Fortran program, MPRINT, written to simplify printing for users. The MPRINT program simplifies the choice of printers and print forms for users of VAX print queues by allowing them to select from a one line per queue menu. The menu includes queue descriptions and only lists printers which can correctly print the specified file. MPRINT selects the correct form to use based on file type and maximum record length of the file. MPRINT may be useful at your site, and provides examples of a number of system services. MPRINT includes routines to do a user open of a file and get information from the File and Record Access Blocks (FAB and RAB), and a routine to obtain information about print queues. There are also routines to parse a file name, detab a character buffer, and trim trailing nulls and blanks from a character string.
Assembly of Mesoporous SBA-15 with an Asymmetry Copper Porphyrin and Study of Its Luminescent Property (2012)

The asymmetry porphyrin incorporates into mesoporous molecular sieves SBA-15 which through the reaction of the OH group of SBA-15 with the fluorine group of the porphyrin. The resultant material was characterized by means of XRD, TEM, solid UV/Vis, FTIR and nitrogen adsorption. Results indicate that the channels of SBA-15 have been filled with porphyrins. Luminescent property was studied by solid fluorescent emission and excitation spectra. Result indicates that the property of SBA-15/porphyrin is better than that of the pure porphyrin. Keywords: Assembly, Asymmetry porphyrin, Characterized, Hydrogen bond, Luminescent property, Mesoporous, Mesoporous material, Metal complex, SBA-15, Synthesis.
Nonmyopic adaptive informative path planning for multiple robots (2009)

Many robotic path planning applications, such as search and rescue, involve uncertain environments with complex dynamics that can be only partially observed. When selecting the best subset of observation locations subject to constrained resources (such as limited time or battery capacity) it is an important problem to trade off exploration (gathering information about the environment) and exploitation (using the current knowledge about the environment most effectively) for efficiently observing these environments. Even the nonadaptive setting, where paths are planned before observations are made, is NP-hard, and has been subject to much research.In this paper, we present a novel approach to adaptive informative path planning that addresses this exploration-exploitation tradeoff. Our approach is nonmyopic, i.e. it plans ahead for possible observations that can be made in the future. We quantify the benefit of exploration through the ``adaptivity gap'' between an adaptive and a nonadaptive algorithm in terms of the uncertainty in the environment. Exploiting the submodularity (a diminishing returns property) and locality properties of the objective function, we develop an algorithm that performs provably near-optimally in settings where the adaptivity gap is small. In case of large gap, we use an objective function that simultaneously optimizes paths for exploration and exploitation. We also provide an algorithm to extend any single robot algorithm for adaptive informative path planning to the multi-robot setting while approximately preserving the theoretical guarantee of the single robot algorithm. We extensively evaluate our approach on a \\emph{search and rescue} domain and a scientific monitoring problem using a real robotic system.
Inhibitory effects of Broccolini leaf flavonoids on human cancer cells (2011)

Broccolini (Brassica oleracea Italica × Alboglabra) is a hybrid between broccoli and Gai Lan, also known as Chinese broccoli and Chinese kale. The aim of this study was to assess the antitumor activity of Broccolini leaf flavonoids (BLF). Cell growth inhibition was evaluated using a standard colorimetric MTT assay, cellular morphology was observed using phase contrast microscopy and flow cytometry was introduced to further investigate cells apoptosis effect. The results showed that BLF possess a dose-dependent antiproliferative effects on four human cancer cell lines (SW480, HepG2, Hela, and A549) and apoptosis induction activity on SW480 cell line. Thus, the hybrid species Broccolini could be considered as a functional vegetable with potential in assisting for the treatment of four human cancers examined here.
A Novel Approach of Using Phosphate-spiked Smart Brines to Alter Wettability in Mixed Oil-wet Carbonate Reservoirs (2015)

Abstract Smart waterflooding (SWF), an emerging EOR technique, was first investigated in sandstone reservoirs. However in recent years, the effect of smart water on carbonate reservoirs has gained wide interest. Despite the increasing number of research and publications in this area, the mechanism enhancing the recovery is still not fully understood. Wettability alteration and reduction in interfacial tension (IFT) have been identified as the two most dominant mechanisms. Divalent ions such as sulfate (SO42-) are found by many investigators to show promising results during SWF. However, limited research has been carried out to investigate the effect of trivalent ions. The objective of this study was to investigate the potential of phosphate (PO43-) spiked brines as a viable EOR technique in tight carbonate reservoirs. Seawater with different dilution factors and varying concentration of phosphate ions were investigated against non-phosphate brines. Impact of these brines on wettability alteration was qualitatively monitored by tracking the rate of contact angle change on several aged-carbonate core samples subjected to varying aging periods. Various designed phosphate brines were tested at elevated temperature of 90 °C, and IFT was also measured at both ambient and elevated temperature (90 °C) to complement our findings. To identify the impact of phosphate ions on wettability alteration due to brine/crude oil/rock interactions, carbonate core samples were prepared having initial contact angle ranging from 130° to 160°. The rate of contact angle change observed ranged from 9° to 36° as a function of varying composition of smart brines. A slight decrease in IFT was observed when lower salinity brines were used without phosphate. Phosphate spiked brines show a near surfactant reduction in IFT, compared to the low salinity brines. Smart brines with higher concentration of phosphate achieved better results than those with lower concentration.

Optimal portfolio selection and compression in an incomplete market (2001)

We investigate an optimal investment problem with a general performance criterion which, in particular, includes discontinuous functions. Prices are modelled as diffusions and the market is incomplete. We find an explicit solution for the case of limited diversification of the portfolio, i.e. for the portfolio compression problem. By this we mean that any admissible strategy may include no more than m different stocks concurrently, where m may be less than the total number n of available stocks.
