The Magnetic Amplifier as an Analog Computer Component (1953)

Some of the basic concepts of obtaining desired function characteristics using magnetic amplifiers with idealized core characteristics are presented. The core-characteristic test procedure is explained along with the results of some tests. The effect of parameter variation is shown and the causes of nonlinearities are discussed. Some new magnetic amplifier circuitry is shown and their use in the analog computer field is indicated.
The effect of the 5-HT re-uptake inhibitor fluoxetine on food intake and body weight in healthy male subjects. (1990)

Eleven healthy male subjects of normal body weight received either 60 mg of the 5-HT re-uptake inhibitor fluoxetine (FXT) or matching placebo daily for two weeks, with a minimum one month wash-out period between treatments. Subjects attended on days 1, 8 and 15 from 08.50 h to 15.15 h in each treatment period when food and fluid intake, body weight, pulse and blood pressure, pupil diameter and plasma levels of FXT and NorFXT were measured and visual analogue scales (VAS) for subjective ratings of hunger, satiety, thirst, mood, arousal, nausea and gastric discomfort were completed. The trial was of a double-blind randomised crossover design, each subject acting as his own control. FXT reduced food intake by 15.7 per cent on day 1; by 12.6 per cent on day 8 but not on day 15. Hunger ratings were lowered by FXT on days 8 and 15 but not on day 1. Subjects were less thirsty when taking FXT but there was no concomitant reduction in fluid intake. FXT produced some mydriasis and slowed heart rate. In two weeks treatment with FXT there was a statistically significant weight loss of 1.07 kg compared to a mean weight gain of 0.15 kg on placebo. The incidence of reported side effects was low, drowsiness and stomach discomfort were reported by some subjects on days 8 and 15.
Synthesis of mesoporous ZSM-5 zeolite crystals by conventional hydrothermal treatment (2013)

Well-defined ZSM-5 crystals with tablet habit, uniform size, controllable silica/alumina ratio, and high mesoporosity were prepared using conventional hydrothermal treatment under stirring. The key to obtaining high mesoporosity of the crystals was to stir a synthesis mixture containing a relatively high concentration of alumina.
An efficient CMOS DC offset cancellation circuit for PGA of low IF wireless receivers (2010)

In this paper, the sources of DC offset in the front-ends of wireless systems are discussed and corresponding DC offset cancellation techniques are analyzed. Upon the discussion, a DC negative feedback technique based DC offset canceller, which is concise and easy to be integrated on chip, is elaborated in details by SMIC 0.18μm CMOS process. DC offset detector is an integral part of DC offset canceller. In this paper, an on chip DC offset detection circuit is proposed for the DC negative feedback canceller which can be used in the CMOS programmable gain amplifier (PGA) of a low intermediate frequency (IF) receiver as which in IEEE802.15.4/ZigBee wireless sensor network. Post-simulation and chip measurement results show that the DC offset canceller performs well.
Association learning of likes and dislikes: A review of 25 years of research on human evaluative conditioning. (2001)

Evaluative conditioning refers to changes in the liking of a stimulus that are due to the fact that the stimulus has been paired with other, positive or negative stimuli. Although evaluative conditioning appears to be subjected to certain boundary conditions, significant evaluative conditioning effects have been obtained using a large variety of stimuli and procedures. Some data suggest that evaluative conditioning can occur under conditions that do not support other forms of Pavlovian conditioning, and several models have been proposed to account for these differences. In the present article, the authors summarize the available literature, draw conclusions where possible, and provide suggestions for future research.

Opioid Metabolism and Effects of Cytochrome P450 (2009)

Over the past 10-20 years researchers have enhanced our understanding of the metabolism and risk of drug interactions of numerous medications utilized by patients with pain conditions. Pain patients often are prescribed multiple medications that can inhibit or induce specific cytochrome P450 (CYP450) enzymes. This review will focus on the effect of the CYP450 enzyme system metabolism on opioid agents codeine, fentanyl, hydrocodone, hydromorphone, methadone, morphine, oxycodone, and oxymorphone, as well as the potential effect of these opioids on the metabolism of other medications and vice versa.
How Can I Keep My Drinking Water Safe (2002)

Growth factors in proliferative vitreoretinopathy (1998)

Surgical repair of retinal detachment complicated by proliferative vitreoretinopathy (PVR) remains complex and time consuming. Visual results of such surgery are frequently disappointing. Dissecting the network of growth factors/cytokines involved in PVR is a comparable challenge which may eventually result in improved anatomical and visual outcomes.

Several lines of evidence point to a role for soluble mediators (“growth factors”) in the process of periretinal membrane formation seen in PVR. Firstly, studies of cellular healing responses in other tissues have demonstrated a role for a number of growth factors (sometimes termed “fibrogenic cytokines”) in mediating cellular chemotaxis and proliferation, neovascularisation, extracellular matrix production, wound remodelling, and contraction, processes essential to the normal wound healing response.1 2 Secondly, several in vitro investigations …
Randomized clinical trials in Clinical Rehabilitation (2005)

A randomized clinical trial (RCT) is currently the strongest method for evaluating interventions in clinical practice. RCTs also provide the politically most powerful form of evidence. However it is not necessarily agreed what constitutes an RCT. This editorial explores what might be included within the rubric of 'randomized clinical trial' (and randomized controlled trial) by considering the reasons for using randomization and controls, and by discussing the definitions of clinical and trial. It suggests that the definition used in the Cochrane Glossary is too restricted and needs revision.
Instrument myopia* (1975)

The basis for instrument myopia, the tendency to accommodate inappropriately while viewing through an optical instrument, was investigated in three experiments. The first demonstrated that the distance of a peripheral surround, analogous to a field stop, influences accommodation but that the magnitude of the effect cannot account for instrument myopia. The second experiment re-examined the hypothesis that perceived distance can affect accommodation. The data indicate that perceived distance is unlikely to influence accommodation and does not provide an explanation of instrument myopia. The last experiment tested the hypothesis that instrument myopia is a manifestation of the return of accommodation to an intermediate state of rest or equilibrium in the absence of an adequate stimulus for accommodation. Implications of the intermediate-resting-state hypothesis are discussed.
Subcellular localisation of NS3 in HCV-infected hepatocytes (1999)

Hepatitis C virus (HCV) NS3 is a multifunctional protein with both protease and helicase activities and has been shown to interact with host cell proteins. It is shown that NS3 is present in the hepatocytes from patients with chronic HCV infection by using anti-NS3 antisera. NS3 is detectable in approximately 4% of the hepatocytes from these patients. In most infected cells, NS3 is present in the cytoplasm; however, in a minority of HCV-infected cells, both the cytoplasm and the nucleus or the nucleus on its own are positive for NS3. The presence of NS3 in the nuclei of hepatocytes in chronically infected patients indicates that the protein may play a role other than in virus replication, such as in persistence of HCV infection.
Computed optical emissions from a sonoluminescing bubble (1999)

A sonoluminescing bubble has been modeled as a thermally conducting, partially ionized plasma. The model is more complete than previous models, due to the inclusion of both plasma and normal molecular thermal conduction, vapor pressure, surface tension, the mixing of gas and water vapor in the bubble, and opacities. The model accounts for most of the observed experimental trends, including (i) the asymmetric pulse shape; (ii) the temperature and driving pressure dependence of the pulse width and intensity; and (iii) spectral shapes, in particular, the 300-nm peak in the spectrum of xenon sonoluminescence, which to our knowledge has not been explained by any previous model; and (iv) a hydrodynamic explanation of why water is the ``friendliest'' liquid in which sonoluminescence occurs. The agreement between the calculations and the data, as well as the model's predictions of almost every experimental trend, suggest strongly that the spectral and temporal properties of the emissions of a sonoluminescing bubble are due to adiabatic- or shock-initiated thermal emission from a cool dense plasma.
Graphs and Maps (2013)

Graphs and maps help you reason with data. They also help you communicate results. A good graph gives you the most information in the shortest time, with the least ink in the smallest space (Tufte, 1997). In this chapter, we show you how to make graphs and maps using R. A good strategy is to follow along with an open session, typing (or copying) the code as you read. Before you begin make sure you have the following data sets available in your workspace. Do this by typing . . . > SOI = read.table("SOI.txt", header=TRUE) > NAO = read.table("NAO.txt", header=TRUE) > SST = read.table("SST.txt", header=TRUE) > A = read.table("ATL.txt", header=TRUE) > US = read.table("H.txt", header=TRUE) . . . Not all the code is shown but all is available on our Web site. It is easy to make a graph. Here we provide guidance to help you make informative graphs. It is a tutorial on how to create publishable figures from your data. In R you have several choices. With the standard (base) graphics environment, you can produce a variety of plots with fine details. Most of the figures in this book use the standard graphics environment. The grid graphics environment is even more flexible. It allows you to design complex layouts with nested graphs where scaling is maintained upon resizing. The lattice and ggplot2 packages use grid graphics to create more specialized graphing functions and methods. The spplot function for example is plot method built with grid graphics that you will use to create maps. The ggplot2 package is an implementation of the grammar of graphics combining advantages from the standard and lattice graphic environments. It is worth the effort to learn. We begin with the standard graphics environment. A box plot is a graph of the five-number summary. The summary function applied to data produces the sample mean along with five other statistics including the minimum, the first quartile value, the median, the third quartile value, and the maximum. The box plot graphs these numbers. This is done using the boxplot function.
Nanostructured Nickel Phosphide as an Electrocatalyst for the Hydrogen Evolution Reaction (2013)

Nanoparticles of nickel phosphide (Ni2P) have been investigated for electrocatalytic activity and stability for the hydrogen evolution reaction (HER) in acidic solutions, under which proton exchange membrane-based electrolysis is operational. The catalytically active Ni2P nanoparticles were hollow and faceted to expose a high density of the Ni2P(001) surface, which has previously been predicted based on theory to be an active HER catalyst. The Ni2P nanoparticles had among the highest HER activity of any non-noble metal electrocatalyst reported to date, producing H2(g) with nearly quantitative faradaic yield, while also affording stability in aqueous acidic media.
Regulation of mammalian acetyl-CoA carboxylase (2002)

Acetyl-CoA carboxylase (ACC) plays a critical role in the regulation of fatty acid metabolism and its two isoforms, ACCalpha and ACCbeta, appear to have distinct functions in the control of fatty acid synthesis and fatty acid oxidation, respectively. They are regulated by similar short-term mechanisms of allosteric activation by citrate, and reversible phosphorylation and inactivation, and there is clearly interaction between these mechanisms. AMP-activated protein kinase is the important physiological ACC kinase for both isoforms and yet there is a potential physiological role for cAMP-dependent protein kinase in the hormonally mediated inactivation of ACCalpha, and phosphorylation of ACCbeta in its unique N-terminus.
Fabrication of Photoswitchable and Thermotunable Multicolor Fluorescent Hybrid Silica Nanoparticles Coated with Dye-Labeled Poly(<i>N</i>-isopropylacrylamide) Brushes (2009)

We report on the fabrication of hybrid silica nanoparticles densely grafted with thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) brushes with inner and outer layers selectively labeled with fluorescence resonance energy transfer (FRET) donors, 4-(2-acryloyloxyethylamino)-7-nitro-2,1,3-benzoxadiazole (NBDAE), and photoswitchable acceptors, 1′-(2-methacryloxyethyl)-3′,3′-dimethyl-6-nitro-spiro(2H-1-benzo-pyran-2,2′-indoline) (SPMA), respectively, via surface-initiated sequential atom transfer radical polymerization (ATRP). P(NIPAM-co-NBDAE)-b-P(NIPAM-co-SPMA) brushes at the surface of silica core exhibit collapse in the broad temperature range of 20−37 °C. UV irradiation of the aqueous dispersion of hybrid silica nanoparticles induces the transformation of SPMA moieties in the outer layer of polymer brushes from nonfluorescent spiropyran (SP) form to fluorescent merocyanine (MC) form, leading to occurrence of the FRET process between NBDAE and SPMA residues. Most importantly, the FRET efficiency can be facilely tuned via thermo-induced collapse/swelling of P(NIPAM-co-NBDAE)-b-P(NIPAM-co-SPMA) brushes by changing the relative distance between donor and acceptor species located within the inner and outer layers of polymer brushes, respectively. Thus, hybrid silica nanoparticles coated with P(NIPAM-co-NBDAE)-b-P(NIPAM-co-SPMA) brushes can serve as a sensitive ratiometric fluorescent thermometer. On the other hand, when the hybrid nanoparticle dispersion was irradiated with visible light again after UV irradiation, the MC form of SPMA moieties reverts back to the nonfluorescent SP form, leading to the turn-off of FRET process. Overall, aqueous dispersion of this novel type of hybrid silica nanoparticle is capable of emitting multicolor fluorescence, which can be facilely tuned by UV irradiation, visible light, and temperatures or a proper combination of these factors.
Lipoprotein(a) in Type 1 Diabetic Patients with Renal Disease (1994)

Lp(a) was measured in 64 normoalbuminuric, 52 microalbuminuric, and 37 proteinuric Type 1 diabetic patients and 54 healthy subjects. Microalbuminuric and proteinuric Type 1 diabetic patients had higher median Lp(a) values (133 (16-1932) and 169 (17-1149) mg l-1) than patients with normal AER (73 (15-1078) mg l-1; p = 0.048 and p = 0.027). Lp(a) in healthy subjects (110 (15-1630)mg l-1) did not differ from the diabetic subgroups. The frequency of Lp(a) values in the upper quarter of the normal distribution was similar in the diabetic groups and did not differ between diabetic and control subjects. The cumulative distribution of Lp(a) was similar in all groups. Lp(a) concentrations were not related to AER, age, gender, duration of diabetes, body mass index, glycaemic control, serum creatinine, free insulin or systolic blood pressure. Cholesterol, LDL-cholesterol, triglycerides, and apo B were higher in microalbuminuric and proteinuric than in normoalbuminuric Type 1 diabetic patients. Lp(a) was independently related to diastolic blood pressure, fibrinogen, and macroangiopathy. In conclusion, median Lp(a) concentrations tend to be higher in Type 1 diabetic patients with early and established renal disease, although the differences are small and the overlap between groups large. Lp(a) is related to diastolic blood pressure and fibrinogen, and this association of powerful risk factors suggests that Lp(a) may play a role in the pathogenesis of cardiovascular disease in Type 1 diabetic patients with proteinuria. Whether Lp(a) is an independent determinant of increased cardiovascular risk in these patients needs to be elucidated by prospective studies.

The RAND Tablet: A Man-Machine Graphical Communications Device (1964)

The RAND tablet was one of the first devices permitting the input of handwritten text and freehand drawings into a computer. While limited in its capabilities and far too expensive for commercial use, the RAND Tablet nonetheless showed the way for PalmPilots, Tablet PCs, and iPads.
Enterohemorrhagic Escherichia coli associated with hemolytic-uremic syndrome in Chilean children (1992)

A clinicoepidemiological study was undertaken to determine if enterohemorrhagic Escherichia coli (EHEC) was associated with hemolytic-uremic syndrome (HUS) in children in Santiago, Valdivia, and Temuco, Chile. Prospective surveillance detected 20 hospitalized cases of HUS in children less than 4 years of age in these cities from March 1988 to March 1989. Each HUS patient was matched (by sex and age) with two control children (hospitalized elective-surgery patients). To detect EHEC, DNA from stool culture isolates of E. coli was detected by hybridization with biotin-labelled DNA probes specific for the EHEC virulence plasmid, Shiga-like toxin I (SLT-I) or SLT-II. Stool cultures from 6 of 20 cases (30%) and from 2 of 38 controls (5.3%) yielded EHEC (P = 0.0158). EHEC isolates from all HUS cases hybridized with the EHEC plasmid probe and with probes for SLT-I or -II (or both). The serogroups of the isolates included O157, O26, and O111. EHEC causes HUS in Chile, and the biotinylated gene probes are practical diagnostic tools for epidemiologic studies.
Learning monocular visual odometry with dense 3D mapping from dense 3D flow (2018)

This paper introduces a fully deep learning approach to monocular SLAM, which can perform simultaneous localization using a neural network for learning visual odometry (L-VO) and dense 3D mapping. Dense 2D flow and a depth image are generated from monocular images by sub-networks, which are then used by a 3D flow associated layer in the L-VO network to generate dense 3D flow. Given this 3D flow, the dual-stream L-VO network can then predict the 6DOF relative pose and furthermore reconstruct the vehicle trajectory. In order to learn the correlation between motion directions, the Bivariate Gaussian modelling is employed in the loss function. The L-VO network achieves an overall performance of 2.68% for average translational error and 0.0143 deg/m for average rotational error on the KITTI odometry benchmark. Moreover, the learned depth is fully leveraged to generate a dense 3D map. As a result, an entire visual SLAM system, that is, learning monocular odometry combined with dense 3D mapping, is achieved.
Water-Soluble Diketopiperazine Receptors - Selective Recognition of Arginine-Rich Peptides (2005)

The selective recognition of arginine-rich peptides by diketopiperazine receptors in aqueous solution is presented. The binding properties of the easily prepared receptors were elucidated by on-bead screenings with a combinatorial split-and-mix peptide library.
Coffee Development of Appropriate Technology for Processing of Machine Harvested Arabica (1992)

In Australia and increasingly overseas, a viable coffee culture can only exist under a fully mechanised regime incorporating the use of mechanical harvesters. Traditionally coffee is selectively hand-picked in prime (red) condition. Existing processing equipment however is incapable of successfully handling mechanically harvested feedstock, which will always contain a mixture of immature, prime and overripe cherry. Innovative, yet low technology processing techniques and equipment has been developed to produce prime quality coffee from machine-harvested feedstock.
A rotor platform assisted system for 3D hairstyles (2002)

We recently reported our experience searching for patients with primary biliary cholangitis (PBC) who were lost in the health system. Our search of databases in 4 hospitals, 3 of which were tertiary institutions, revealed that sufficient data were available to ensure a reliable diagnosis (i.e., cholestasis, positive antimitochondrial antibody titer, and no other liver disease) in 14.3 % (100/697) of PBC cases. However, patients remained undiagnosed, thus missing an opportunity to start early treatment and follow-up. Even more strikingly, of 30 rescued patients, 27 % had an elastography result indicating a poorer prognosis (> 9.5 kPa).
Interleukin-6 induces the synthesis of tissue inhibitor of metalloproteinases-1/erythroid potentiating activity (TIMP-1/EPA) (1991)

This study examines the role of interleukin-6 (IL-6) in connective tissue metabolism. Effects of different preparations of IL-6 on production of collagenase and tissue inhibitor of metalloproteinases-1/erythroid potentiating activity production are studied in human fibroblasts, synoviocytes, and articular chondrocytes. In contrast to interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF alpha), IL-6 does not stimulate the production of collagenase, nor does it modulate the stimulatory effects of IL-1 beta and TNF alpha on the production of this proteinase. Furthermore, IL-6 has no detectable effect on prostaglandin E2 production, an additional proinflammatory response induced by IL-1 beta and TNF alpha. IL-6, however, is identified as a potent inducer of de novo synthesis of tissue inhibitor of metalloproteinases-1/erythroid potentiating activity in all types of connective tissue cells examined. These results define new biological activities of IL-6 and provide further insight into the regulation of connective tissues by cytokines.
