A Procedure for Detecting Intersections of Three-Dimensional Objects (1968)

As a step toward the solution of the placement problem in engineering design, a procedure has been developed for detecting intersections of convex regions in 3-space by means of a pseudocharacteristic function. The mathematical techniques underlying the procedure are discussed, and a system of programs embodying these techniques is described. As a special case a solution is given for the hidden-line problem in graphic display.
CDM-reliable T-coil techniques for high-speed wireline receivers (2015)

An inherent CDM hazard exists in T-coil circuits due to magnetic coupling. An “inductance halving” technique is proposed to reduce magnetic coupling during ESD. From simulation, the proposed solution can effectively suppress voltage overshoot and minimize bandwidth degradation, compared to the conventional secondary ESD protection.
Use of aquarium fish, Danio rerio and Poecilia reticulata, as test species for evaluation of nitrosamine carcinogenicity. (1984)

The carcinogenic effects of various doses of dimethylnitrosamine (DMNA), diethylnitrosamine (DENA), and nitrosomorpholine (NM), as well as the results of varying temperature and length of exposure to these carcinogens, were studied in short-term (20-21 wk) experiments in aquarium fish (820 Danio rerio and 944 Poecilia reticulata). All nitroso compounds induced liver tumors (hepatocellular carcinomas and adenomas, cholangiomas, and cholangiocarcinomas) and esophageal papillomas. Exposure to NM also induced intestinal adenocarcinomas in D. rerio. At a conventional temperature (22 degrees +/- 1 degree C), tumors were induced in 76% of the D. rerio in an average of 13.8 weeks following an initial 8-week exposure to 100 ppm DMNA and in 22% of P. reticulata in an average of 10.9 weeks. The DENA exposure resulted in tumors in 61.5% of Danio by 15 weeks and in 29% of Poecilia in 15.5 weeks. Under the same conditions, 500 ppm NM induced tumors in 78% of the zebra fish in 15.6 weeks and in 75% of the guppies after 12.3 weeks. When exposure time was shortened to 2 weeks, the dosage was decreased, or if the temperature was reduced to 17 degrees +/- 1 degree C, the tumor incidence dropped and the latency increased. An increase in temperature to 27 degrees +/- 1 degree C resulted in a 72-89% tumor incidence and shortened the latency to 11.3-14.1 weeks. Thus the modulation of our experimental conditions to maximize tumor incidence and minimize mean latency permitted the use of the aquarium fish D. rerio and P. reticulata for the screening of carcinogenic nitrosamines.

A finite-difference time-domain near zone to far zone transformation (electromagnetic scattering) (1991)

An efficient time-domain near-zone-to-far-zone transformation for FDTD (finite-difference-time-domain) computations is presented. The approach is to keep a running accumulation of the far-zone time-domain vector potentials due to the tangential electric and magnetic fields on a closed surface surrounding the scatterer at each time step. At the end of the computation, these vector potentials are converted to time-domain far-zone fields. Many far-zone bistatic directions can be included efficiently during one FDTD computational run. Frequency domain results can be obtained via fast Fourier transform. Wideband results for scattering from a perfectly conducting plate were obtained from a single FDTD computation transformed to the frequency domain, and compared with moment method results. This approach is significantly more efficient than computing many FDTD results using sinusoidally varying excitation if a wide frequency band is of interest. Coupled with recent advances in computing FDTD results for frequency-dependent materials, wideband results for far-zone scattering from targets including frequency-dependent materials can be obtained efficiently.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Introduction to the Magnetic Properties of New England Granitoids (1984)

The l-type and S-type granitoids of New England, NSW, generally equate to the magnetite-series and ilmenite-series classification. The only non-conforming suite is the Uralla l-type suite which is non-magnetic, but these granitoids also exhibit several abnormal geochemical parameters. The Triassic leuco-adamellites are also non-magnetic, but exhibit magnetic aureoles. Limited remanence measurements are available. Samples of two late-Triassic plutons show strong remanence, indicating allowance will have to be made for such effects in quantitative analysis of magnetic data.
The Effect of Oxidation/Reduction of Sulfide Mineral on Its Recovery by Flotation (2007)

The influence of oxidation on the floatability of sulfide minerals contained in mine failings has been investigated employing chalcopyrite as a target material. The critical surface tension of chalcopyrite was estimated to be about 15.5 dyne/cm based on Zisman plot and the floatability of chalcopyrite was observed to increase with the concentration of collector. The enhanced float-ability of chalcopyrite at its initial stage of oxidation was considered to be due to the transformation of disulfide to elemental sulfur and the decrease in its floatability at further oxidation was presumably caused by the formation of sulfate and/or disulfur trioxide from elemental sulfur. When the oxidized chalcopyrite was reduced, its floatability was increased and the variation of the critical surface tension of chalcopyrite according to tile oxidation/reduction was interpreted by an energy diagram constructed by different bond energies between atoms.
Toy-gun pellet-related ocular trauma on festive occasions. (2018)

BACKGROUND: Toy-guns with plastic pellets are used on festive and social occasions by children in Pakistan. Assuming these guns as toys and incapable to cause severe ocular damage, these are favorites, cheap and easily available without age restriction. PURPOSE: Reporting the data, treatment methods and results of the patients sustaining eye injuries with toy gun pellets. SUBJECTS & METHODS: Prior permission was sought from Institutional Review Board of King Edward Medical University, Lahore. This is a retrospective analysis of patients with toy gun eye injuries who presented at Ophthalmology Unit-I, Mayo hospital Lahore, from January 2017 to May 2018. We observed demographic data and the type of injuries to the eyes, choice of treatment and visual acuity after treatment. RESULTS: Thirty (30) patients (22 male & 8 females) with ocular injuries due to Toy gun plastic pellets were included in this study. Gun pellet casualties were common in a young male with mean age 13.63 years ranging 4½ to 40 years. Most injuries to the globe were without laceration (n=20) and were unilateral (n=30). Most common ocular injury encountered was corneal abrasions (36.60%), followed by hyphema(33.33%) and corneal laceration (13.30%). No case of vitreous haemorrhage, retinal detachment, or intraocular foreign body was reported. Cases were managed conservatively. Corneoscleral laceration repair was done in four (04) cases while cataract surgery was done in two (02) cases only. CONCLUSION: Ocular injuries resulting from pellets of plastic toy guns are quite significant in number among the younger population on festive occasions. It is desirable to report pellet related ocular injuries and their disastrous impact on visual acuity for proper public education.
Visualization in Interrogator using Graphviz (2006)

The Interrogator infrastructure is comprised of a number of networks each consisting of multiple thousands of nodes. The data produced by the sensors in this infrastructure is collected and stored in three distinct formats: relational databases, data files containing packet traffic or network flow information, and other report files - usually in extensible markup language (XML) format. In a network infrastructure of this size, it becomes very difficult to keep abreast of the complex relationships that exist within. Additionally, due to the sheer volume of data produced in the previously mentioned formats, a method to aid in extracting the security relevant content from the data becomes highly essential. We propose the use of network graphs to address these limitations in the current Interrogator architecture. Generation of the graphs required the development of methods to extract - from the data sources available - the needed connectivity and data transfer information. This information was then passed to a graphing utility, Graphviz, which was used to generate the network graphs. Using the capabilities provided in Graphviz, we were able to quickly obtain information about any node in the network including: the connectivity of the node, the data transferred, and any alerts generated that included these nodes. These graphs are used as another analysis source for an analyst to aid in the identification of suspicious network behavior
Prescribing for Older Patients (2020)

Older patients, particularly if debilitated, deserve special thought when prescribing. With a rapidly ageing population, every clinician must be comfortable prescribing for this unique set of patients. While it is important to consider frailty, cognitive impairment and declining organ function, clinicians must also beware of physical barriers to drug adherence, the hazardous effects of polypharmacy and of the importance of shared decision-making when making treatment decisions. These complex issues and others are discussed in this chapter.
Design Aspects of Conductive Microfiber Rings for Shaft Grounding Purposes (2007)

Carbon brushes using electrically conductive carbon graphite have been used for shaft-grounding and current-conduction purposes for a long time. We present an alternative brush concept made from millions of conductive microfibers. If properly designed, such brushes can meet all the demands on carbon brushes but exclude the problems of excessive wear and hot-spotting/thermal wear commonly quoted with the first. These brushes have negligible frictional wear, are free of maintenance, and robust towards contamination. In addition, they are especially suitable for use with high-frequency currents and voltages, as they also allow current- conduction based on electric field emission. We develop the design criteria for such brushes both for prevention of voltage build-up and current-conduction of several 10s of Amperes with frequencies in the MHz range. We support the theoretical results with measurement results taken at different rotor shaft speed.
[Relationship between irradiation and appearance of brain tumors in rats]. (1994)

Sprague-Dawley rats were exposed to Co 60 irradiation (3 Gy) at different ages. Rats were distributed among sham-control (618 males and 120 females) and exposed groups: foetus (66 males and 65 females), 3 month-old (304 males), and 9 month-old (120 males and 60 females). The incidence of brain tumours was 5.3% in male control rats and nil in female control rats. Brain tumour incidence decreased in 9 month-old rats (3.3%), and increased from 6.6% in 3 month-old rats to 15.2% in male foetuses and 12.3% in female foetuses. Age at incidence of brain tumours decreased in irradiatiated animals. Astrocytomas were the more susceptible type of brain tumours to radiocarcinogenesis.
[Anomalous excretion of glycosaminoglycans in patients with syringomyelia]. (1992)

Glycosaminoglycan (GAG) urine concentrations in syringomyelia patients were much higher than in healthy subjects from January to September. Maximum values of GAG excretion (twice as much as control) in affected patients were observed in spring and summer (from March to July). The results suggest that syringomyelia is accompanied by disorders in GAG connective tissue accumulation.
Maximum leaf conductance driven by CO <sub>2</sub> effects on stomatal size and density over geologic time (2009)

Stomatal pores are microscopic structures on the epidermis of leaves formed by 2 specialized guard cells that control the exchange of water vapor and CO(2) between plants and the atmosphere. Stomatal size (S) and density (D) determine maximum leaf diffusive (stomatal) conductance of CO(2) (g(c(max))) to sites of assimilation. Although large variations in D observed in the fossil record have been correlated with atmospheric CO(2), the crucial significance of similarly large variations in S has been overlooked. Here, we use physical diffusion theory to explain why large changes in S necessarily accompanied the changes in D and atmospheric CO(2) over the last 400 million years. In particular, we show that high densities of small stomata are the only way to attain the highest g(cmax) values required to counter CO(2)"starvation" at low atmospheric CO(2) concentrations. This explains cycles of increasing D and decreasing S evident in the fossil history of stomata under the CO(2) impoverished atmospheres of the Permo-Carboniferous and Cenozoic glaciations. The pattern was reversed under rising atmospheric CO(2) regimes. Selection for small S was crucial for attaining high g(cmax) under falling atmospheric CO(2) and, therefore, may represent a mechanism linking CO(2) and the increasing gas-exchange capacity of land plants over geologic time.
Colostomy irrigation survey: The Australian STN experience (2016)

Before the new Colostomy Irrigation Patient Information Pamphlet became available from the Education and Professional Development Committee (E and PDC) it was considered prudent to survey all AASTN members to ascertain the current prevalence of irrigation as a colostomy management option, the opportunity for members to teach the procedure and the education of STNs and patients about the procedure.
An automated retinal image quality grading algorithm (2011)

This paper introduces an algorithm for the automated assessment of retinal fundus image quality grade. Retinal image quality grading assesses whether the quality of the image is sufficient to allow diagnostic procedures to be applied. Automated quality analysis is an important preprocessing step in algorithmic diagnosis, as it is necessary to ensure that images are sufficiently clear to allow pathologies to be visible. The algorithm is based on standard recommendations for quality analysis by human screeners, examining the clarity of retinal vessels within the macula region. An evaluation against a reference standard data-set is given; it is shown that the algorithm's performance correlates closely with that of clinicians manually grading image quality.
Color Image Segmentation (1993)

Segmentation is a key problems in image processing. In the framework of mathematical morphology the traditional method of segmentation is based on the watershed transform. This method may be analysed as a region growing algorithm, starting from a set of markers for all zones of interest. The author extends it to the segmentation of color images and illustrates it, with paintings.<

Emergency Defibrillation Using a Temporary Pacing Electrode Catheter (1985)

Direct application of electrical current to the heart utilizing special equipment such as implantable defibrillators or specially designed catheters has been useful in patients with recurrent ventricular tachyarrhythmias. We describe a patient who developed intractable ventricular fibrillation (VF) during the course of electrophysiologic testing. VF continued for 50 minutes, during which time multiple transthoracic shocks of 360 joules failed to convert the arrhythmia. Intracardiac shocks were then delivered via a transvenous 6 French standard quadripolar pacing catheter positioned in the right ventricular apex by direct application of the defibrillator paddle to the catheter, with the patient lying on the posterior paddle. Energy of up to 300 joules failed to defibrillate the patient, but use of 360 joules delivered in this fashion defibrillated the patient twice. Despite the protracted time of cardiac arrest, the patient recovered without sequelae. We report this case to demonstrate that VF refractory to transthoracic defibrillation may be converted by intracardiac shocks using a temporary pacing catheter without special equipment.
Resolving the Sugar and Health Controversy with Special Reference to Malaysia (2018)

Background: It is alleged that the incidence of obesity, type 2 diabetes mellitus (T2DM), and metabolic syndrome (MetS) have sharply increased throughout the world. It is generally argued that increased consumption of a calorie-rich/ high-fat diet, lack of exercise, and sedentary-lifestyles are responsible, besides increasing age, gender, and obesity itself. But, certain authors argue that increased consumption of a carbohydrate-rich diet high in sucrose, fructose, and/or glucose is responsible for the increasing incidence of obesity, T2DM, and MetS. The same proponents also claim that these sugars cause cancers and other chronic diseases through ‘chronic low-grade inflammation’, besides directly. Some yet argue against these claims, causing an on-going raging international controversy, with strong implications for Malaysia. Objective: The aim is to resolve this controversy through an appropriate literature-review. Methodology: Literature from both sides, such as journal-articles, systematic-reviews, meta-analyses and booksummaries were reviewed, besides videos of lectures uploaded onto YouTube. Results: Although here is observed for and against claims that sugar, especially sucrose and fructose, is an addictive, toxic-substance capable of causing chronic-diseases and, being the main cause of obesity, the evidence is overwhelmingly against such claims. Almost all of the studies for appear to have been done on rats and cell-lines, and not of an epidemiological-study nature. Even the nature of the metabolism of sugars claimed as conclusions from these studies is doubted by different studies/articles. The ACGIH categorizes sucrose as not classifiable as human or animal carcinogen. Current existing guidelines on dietary-sugar do not seem to meet criteria for trustworthy recommendations. Conclusion: The evidence is overwhelmingly against claims that sugar causes chronic diseases, and that sugar is the main cause of obesity. There is a need for more epidemiological-studies.
Detection of genomic polymorphisms among isolates of the intracellular bacterium Cowdria ruminantium by random amplified polymorphic DNA and Southern blotting (1997)

Sixteen primers were successfully used in a RAPD assay to generate reproducible fingerprints for six isolates of Cowdria ruminantium, a tick-transmitted rickettsia of ruminants. Distinction between stocks was possible by using one or at most two primers. Two stocks were very similar although originating from widely distant geographical regions. A genetic distance tree was constructed by analysing 108 fragments in pairwise comparison between stocks. Three amplification fragments probed with C. ruminantium genomic DNA determined a restriction fragment length polymorphism which allowed the distinction between stocks except for the two stocks that had similar RAPD patterns. The potential of RAPD to determine the extent of genetic diversity of C. ruminantium and to develop probes or PCR primers for diagnostic purposes is discussed.
3D visualization of carbonate reservoirs (2003)

Conventional 2D and 3D seismic mapping is not ideal for characterizing carbonate reservoirs mainly because of the complexity and heterogeneity of carbonate systems. The unique depositional systems of carbonate environments means that a standard interpretation routine is often inadequate and more sophisticated techniques are needed.
Guidelines of the European Society of Gastrointestinal Endoscopy (E.S.G.E.) antibiotic prophylaxis for gastrointestinal endoscopy. European Society of Gastrointestinal Endoscopy. (1998)

There are two situations when antibiotic prophylaxis is recommended. The first is associated with procedures known to be followed by high rates of bacteraemia, involving organisms prone to cause endocarditis. These include oesophageal dilatation, variceal sclerotherapy and laser therapy in the upper gastrointestinal tract. As bacteraemia following these procedures is usually harmless in average risk patients antibiotic prophylaxis is recommended only for a patient with a lesion susceptible to endocarditis or one who is at increased risk of symptomatic bacteraemia due to neutropenia or immunosuppression. In most cases parenteral amoxycillin and gentamicin is recommended plus metronidazole for neutropenic patients. Vancomycin or teicoplanin replace amoxycillin in a case of allergy. The second situation concerns procedures with a high incidence of local infection or which may lead to serious sepsis. These include therapeutic retrograde cholangiopancratography and percutaneous endoscopic gastrostomy where antibiotic prophylaxis is recommended even in average risk patients. Several antibiotics are recommended including oral ciprofloxacin or parenteral gentamicin or quinolone for ERCP and amoxycillin for PEG or cephalosporin or ureidopenicillin for both.
