Temporally incoherent magnetic fields mitigate the response of biological systems to temporally coherent magnetic fields (1994)

We have previously demonstrated that a weak, extremely-low-frequency magnetic field must be coherent for some minimum length of time (approximately 10 s) in order to affect the specific activity of ornithine decarboxylase (ODC) in L929 mouse cells. In this study we explore whether or not the superposition of an incoherent (noise) magnetic field can block the bioeffect of a coherent 60 Hz magnetic field, since the sum of the two fields is incoherent. An experimental test of this idea was conducted using as a biological marker the twofold enhancement of ODC activity found in L929 murine cells after exposure to a 60 Hz, 10 microT rms magnetic field. We superimposed an incoherent magnetic noise field, containing frequencies from 30 to 90 Hz, whose rms amplitude was comparable to that of the 60 Hz field. Under these conditions the ODC activity observed after exposure was equal to control levels. It is concluded that the superposition of incoherent magnetic fields can block the enhancement of ODC activity by a coherent magnetic field if the strength of the incoherent field is equal to or greater than that of the coherent field. When the superimposed, incoherent noise field was reduced in strength, the enhancement of ODC activity by the coherent field increased. Full ODC enhancement was obtained when the rms value of the applied EM noise was less than one-tenth that of the coherent field. These results are discussed in relation to the question of cellular detection of weak EM fields in the presence of endogenous thermal noise fields.
Male reproductive success and population control in the Mediterranean Fruit Fly, Ceratitis capitata (2012)

The traits that determine male reproductive success in Ceratitis capitata (medfly) are largely unknown. This comes despite decades of research into the reproductive behaviour of this agricultural pest. An understanding of what makes a successful male is of great importance in this lekking species, as one male has the ability to dominate access to females. In addition species-specific pest control techniques such as the Sterile Insect Technique (SIT) and Release of Insects carrying a Dominant Lethal (RIDL) rely on the mating competitiveness of mass-reared ‘sterile’ males to disrupt natural mating systems and reduce population numbers. However, it is well known that the mass-rearing process required to generate these individuals produces less competitive males, despite this an understanding of the sexual selection processes that are involved is severely lacking. In this thesis I used the medfly as a model organism to investigate the context-dependent nature of male reproductive success. In Chapters 2 and 3 I investigate the effect of manipulating the adult sex ratio on pre- and post-mating reproductive traits. Chapter 2 uses proximate\nmanipulation of the adult sex ratio to show how the relationship between pre- and post-mating success is affected by the levels of male competition. Chapter 3 shows that selection lines are unable to select for the traits that predict male reproductive success under altered levels of male competition. Chapter 4 describes the attempts to produce RIDL genetic constructs with embryonic lethality. Chapter 5 demonstrates that RIDL lines of medfly display characteristics that make them suitable for wild population control and may exceed the performance of existing SIT lines. Chapter 6 shows that manipulation of the larval diet can alter the gut microbiota of adults; however these manipulations have no effect on reproductive behaviour. Instead there was a significant effect of high-sugar larval rearing on mating success and body mass. This effect persisted for a single generation in offspring of these flies, even when they were reared on an inferior starch-based larval diet. Finally Chapter 7 summarises the thesis and discusses the implications of this work and future directions for both research in the reproductive behaviour of the medfly, and the future of RIDL technology in medfly population control.

A Method of Modeling the Directional Behavior of Bottomhole Assemblies Including Those With Bent Subs and Downhole Motors (1986)

ABSTRACT This paper presents an analytical model that has successfully predicted the inclination directional behavior of rotary drilling bottomhole assemblies, including assemblies that contain bent subs and downhole motors. The model has been installed as part of the Engineering Simulator for Drilling (ESD), and combines the effects on directional behavior of bottomhole assembly configuration, hole geometry, rock drillability, bit type and operating parameters such as bit hydraulics, weight-on-bit and rotary speed. The model combines previous work dealing with bottomhole assembly analysis and bit mechanics (including side-cutting behavior), with original work defining the manner by which bits directionally penetrate. The model's computation scheme depends on a microcoded version of a finite element bottomhole assembly behavior program running on an array processor. The system provides solutions of the finite element routine every one to six seconds. Solutions are required at this frequency in order to obtain stable directional predictions at 30 times faster than real time. The paper also shows that comparisons of the model results with field data are good in areas where formation affects are benign. Comparisons of model predictions with field results in areas of significant formation directional affects are also shown. These comparisons are useful in quantifying the effect of the dip and strike on directional behavior, and in defining areas where future work is needed.
Using Machine-Learning to Efficiently Explore the Architecture/Compiler Co-Design Space (2010)

Designing new microprocessors is a time consuming task. Architects rely on slow simulators to evaluate performance and a significant proportion of the design space has to be explored before an implementation is chosen. This process becomes more time consuming when compiler optimisations are also considered. Once the architecture is selected, a new compiler must be developed and tuned. What is needed are techniques that can speedup this whole process and develop a new optimising compiler automatically. This thesis proposes the use of machine-learning techniques to address architecture/compiler co-design. First, two performance models are developed and are used to efficiently search the design space of amicroarchitecture. These models accurately predict performance metrics such as cycles or energy, or a tradeoff of the two. The first model uses just 32 simulations to model the entire design space of new applications, an order of magnitude fewer than state-of-the-art techniques. The second model addresses offline training costs and predicts the average behaviour of a complete benchmark suite. Compared to state-of-the-art, it needs five times fewer training simulations when applied to the SPEC CPU 2000 and MiBench benchmark suites. Next, the impact of compiler optimisations on the design process is considered. This has the potential to change the shape of the design space and improve performance significantly. A new model is proposed that predicts the performance obtainable by an optimising compiler for any design point, without having to build the compiler. Compared to the state-of-the-art, this model achieves a significantly lower error rate. Finally, a new machine-learning optimising compiler is presented that predicts the best compiler optimisation setting for any new program on any new microarchitecture. It achieves an average speedup of 1.14x over the default best gcc optimisation level. This represents 61% of the maximum speedup available, using just one profile run of the application.
Effects of Navigation Errors in Maneuvering SAR (1973)

A maneuvering synthetic aperture radar in squint mode, during a loosely piloted maneuver, is simulated with presence of various navigation system errors. The error sources investigated place emphasis on short-term effects, involving platform servo transients, noise and quantization in accelerometers, interaction of angle pickoff uncertainty with the displacement from platform to radar antenna, and uncertainty in this displacement itself. Simulation results are accompained by interpretive discussion, and followed by suggested areas for further study.
PHASE LOCKING OF LASER MODES BY CONTINUOUS CAVITY LENGTH VARIATION (1967)

Phase locking of the longitudinal modes of a gas laser has been obtained by translating one of the cavity mirrors at a constant velocity. The velocity required to obtain locking depends almost lineraly on excitation as long as only the fundamental transverse mode is oscillating. No plausible explanation has been found for these effects.
Nerve Injury Induces a Tonic Bilateral μ-Opioid Receptor–mediated Inhibitory Effect on Mechanical Allodynia in Mice (2004)

The authors' observations indicate that (1) unilateral nerve injury induces a bilateral tonic activation of endogenous mu-opioid receptor-mediated inhibition that attenuates mechanical allodynia but not thermal hyperalgesia, (2) both mu- and kappa-opioid agonists attenuate neuropathic pain in mice, and (3) the antihyperalgesic actions of morphine are mediated primarily via mu-opioid receptors.
Physiological and pathophysiological roles of eicosanoids in the microcirculation (1996)

Eicosanoids are important mediators of both physiological and pathophysiological responses of the microcirculation. These biologically active lipid mediators can be produced locally by the cellular elements within the microvasculature (endothelium, pericytes, smooth muscle cells) as well as interstitial cells (e.g. fibroblasts, mast cells) and by various cells in the vascular compartment (e.g. leukocytes, platelets). Transcellular metabolism of intermediates produced by one cell type in close contact with another also has the potential to generate potent metabolites. This review integrates some of the older literature with recent developments in eicosanoid synthesis and release, the molecular advances in the enzymology and receptor specificity of the eicosanoids and the regulation by autocoids and inflammatory mediators. The potential roles of eicosanoids in regulation of local blood flow, vascular reactivity, angiogenesis and leukocyte adhesion and transmigration are discussed.
Therapeutic effect of dopamine infusion on human malignant melanoma. (1982)

Dopamine is a novel antitumor agent that has shown activity against B16 melanoma. Four patients with advanced malignant melanoma were infused with dopamine at 20 micrograms/kg/min for 48--120 hours. Tumor and bone marrow samples were obtained before and after treatment for comparison. Each of the patients tested showed significant reduction in the labeling index of tumor cells following treatment. These results suggest that dopamine is capable of attaining cytotoxic levels necessary to induce a biochemical inhibition of human malignant melanoma.
Survival of Lactobacillus acidophilus and Bifidobacterium bifidum in Ice Cream for Use as a Probiotic Food (1992)

Probiotic ice cream was made by fermenting a standard ice cream mix with Lactobacillus acidophilus and Bifidobacterium bifidum cultures and then freezing the mix in a batch freezer. Survival of the L. acidophilus and B. bifidum, as well as beta-galactosidase activity, was monitored during 17 wk of frozen storage at -29 degrees C. After freezing of the fermented mix, bacterial counts were 1.5 x 10(8) cfu/ml for L. acidophilus and 2.5 x 10(8) cfu/ml for B. bifidum. Seventeen weeks after freezing, these counts had decreased to 4 x 10(6) and 1 x 10(7) cfu/ml, respectively. During the same period, beta-galactosidase activity decreased from 1800 to 1300 units/ml. Probiotic ice cream was prepared at pH 5.0, 5.5, and 6.0 to determine consumer preferences and was compared with standard Utah State University "Aggie" ice cream. All samples were strawberry-flavored and were evaluated by 88 judges. The preferred pH of probiotic ice cream, based on overall acceptance, was pH 5.5. We demonstrated that probiotic ice cream is a suitable vehicle for delivering beneficial microorganisms such as L. acidophilus and B. bifidum to consumers. The bacteria can be grown to high numbers in ice cream mix and remain viable during frozen storage.

Date Palm Tree-Based Fibrous LCM ARC Eco-Fiber -A Better Alternative to Equivalent Imported Products (2018)

Abstract A novel fibrous LCM coined "ARC Eco-Fiber" has been developed using deceased date tree wastes to use as an alternative to equivalent imported products. Every year about 5 to 10% trees are discarded due to old age, poor food bearing capacity and also due to the damage and degradation of trees by diseases. Currently, there is no industrial use of the discarded and deceased date palm trees available in the Kingdom. Moreover, the disposal of the deceased and old trees is a big headache for the date farming communities due to the economic cost and their negative impact on surrounding environment and the existing date farm plants. As there is a sustainable source of discarded and deceased date trees in the Kingdom, it is a potential source of raw material for localization of fibrous LCM product development to replace the equivalent imported products. The industrial use of deceased and old date trees will also boost the growth of local industries and enterprises along with the creation of new job opportunities for the local communities. It will also help to uplift the social and economic condition of the date farming communities. The date palm trunk-based fibrous LCM described in this paper indicates good ductile and malleable characteristics and thus expected to have good tensile and compressive load bearing capacity to prevent damage and degradation while pumping. The performance of the newly developed fibrous LCM "ARC Eco-Fiber" was evaluated using a see-through and a Permeability Plugging Test (PPT) Apparatus. The PPT apparatus used 2mm slotted disc, 250 oF temperature and 1000 psi pressure to conduct the tests. A commercial fibrous LCM product widely used by industry has also been tested to compare the performance of the date palm trunk-based fibrous LCM -ARC Eco-Fiber. The results demonstrated superior sealing and plugging efficiency for the ARC Eco-Fiber with little or no loss of whole mud compared to the widely used commercial fibrous LCM product. Both the conventional and see-through test results indicate effective sealing and plugging performance for the date palm waste-based fibrous LCMs and thus demonstrated the reliability of the product as an alternative to equivalent imported LCM products.
Liquid secondary ion mass spectrometry/Fourier transform mass spectrometry of oligosaccharide anions (1993)

The liquid secondary ionization mass spectrometry of oligosaccharide anions is investigated with an external source quadrupole Fourier transform mass spectrometer (FTMS). Selected linear and cyclic oligosaccharides are analyzed to determine the performance of the external source FTMS in the anion mode. Fragmentation behavior of disaccharides is characterized and related to the fragmentation behavior of larger oligomers. General correlation is found between the linkages and the fragment ions observed.

Quantitative Assessment of Augmentation Therapy (1990)

We report the results obtained from 18 women whose facial folds and furrows were treated with augmentation therapy. The results of treatment with microlipoinjection and injectable collagen were measured and compared at regular intervals for a period of 1 year using a method of optical profilometry. Subsidence was noted with both modalities. Collagen gave consistent results. Seventy-five percent of correction on the average is lost at 6 months, but 22% of the collagen-treated subjects maintained at least 30% correction 1 year from the time of treatment. Autologous fat gave unpredictable results ranging from poor to excellent. A good result at 6 months is likely to be maintained until 1 year from the time of treatment. Forty-four percent of fat augmented subjects maintained at least 30% correction 1 year after treatment.

A bioreactor system for clinically relevant bone tissue engineering (2010)

Similar to bioreactors in classical applications, the key functions of bioreactors in tissue engineering are to provide control and standardization of physiochemical culture parameters during cell/tissue culture. Bioreactors can improve the quality (i.e. cell distribution and cell utilization) and reproducibility of the process of seeding cells into 3D porous scaffolds. Mass transport of nutrients and waste products to and from cells within engineered constructs can be enhanced by convective bioreactor systems. Bioreactors which perfuse media directly through the scaffold have the greatest potential to eliminate mass transport limitations and maintain cell viability within large 3D constructs. Mechanical conditioning within controlled bioreactor systems has the potential to improve the structural and functional properties of engineered tissues. However, optimizing the operating parameters (i.e. which specific mechanical force(s) and regimes of application) for a particular tissue will require significant quantitative analysis and computational modeling. By recapitulating aspects of the actual cellular microenvironment that exists in vivo, bioreactors can provide in vitro model systems to investigate cell function and tissue development in 3D environments. Design and development of a tissue engineering bioreactor system should be approached as for classical engineering problems: define the problem, conceptualize the solution, develop a prototype, quantify reactor performance, refine the design, validate reactor performance. Innovative and low-cost bioreactor systems that automate, standardize and scale the production of a tissue-engineered product will be central to future manufacturing strategies, and will play a key role in the successful exploitation of an engineered product for widespread clinical use.
Feasibility study of a new method for low-complexity fetal movement detection from abdominal ECG recordings (2016)

<p>Fetal movement counting can provide valuable information on the fetal health, as a strong decrease in the number of movements can be seen as a precursor to fetal death. Typically, assessment of fetal health by fetal movement counting relies on the maternal perception of fetal activity. The percentage of detected movements is strongly subject dependent and with undivided attention of the mother varies between 37% and 88%. Various methods to assist in fetal movement detection exist based on a wide spectrum of measurement techniques. However, these are unsuitable for ambulatory or long-term observation. In this paper, a novel low-complexity method for fetal movement detection is presented based on amplitude and shape changes in the abdominally recorded fetal ECG. This method was compared to a state-of-the-art method from the literature. Using ultrasound-based movement annotations as ground truth, the presented method outperforms the state-of-the-art abdominal-ECG based method, with a sensitivity, specificity, and accuracy of 56%, 68%, and 63%, respectively. Additionally, a significant reduction in algorithm complexity is achieved, possibly enabling continuous ambulatory fetal movement detection and early detection of reduced fetal motility.</p>
High pressure treatment of liquid whole egg and advantages of low temperature application (2000)

Abstract High hydrostatic pressure in combination with controlled temperature could be an alternative process for prolonging the shelf life of liquid whole egg (LWE). As a first step of process optimisation, the equivalent lines of pressure-induced coagulation are provided at three different temperatures (5°C, 25°C and 45°C). The excess work of structure breakdown (ΔW) was calculated from rheological measurements and used as a parameter for the degree of coagulation. Below the line of ΔW = 5.0 kj/m3, the rheological properties of processed LWE were comparable to those of fresh LWE, considered as a critical value. Pressure treatment at higher temperature caused increased coagulation and allowed only a limited possibility of performing high pressure treatment. Furthermore, the inactivation kinetics of E. coli in LWE showed that temperature optima for inactivation could also be found in the low temperature region.
