Aluminium-27 nuclear magnetic resonance investigations of highly alkaline aluminate solutions (1984)

The high-field 27Al n.m.r spectra are reported of three solutions from which solid materials can be crystallised containing either a dimeric anion with tetrahedrally co-ordinated aluminium or anions with octahedrally co-ordinated aluminium. In two cases the principal ionic species present in solution is [Al(OH)4]– and only in the case of a sodium aluminate solution is evidence obtained that significant concentrations of species exist in solution prior to crystallisation which may be related in composition to that of the crystalline products.
Information Rx: Evaluation of a new informatics tool for physicians, patients, and libraries (2006)

This paper reports selected results from two comprehensive evaluation studies of the Information Prescription (or "Information Rx") Program implementation conducted from 2002-05 by the American College of Physicians Foundation (ACPF) and the U.S. National Library of Medicine (NLM). In this Program physicians are provided with Information Prescription pads, analogous to pads used to prescribe medications, that are used to direct patients to the MedlinePlus web site and its contents that are applicable to a patient's health condition. The results describe the Program's potential to enhance patient education and interpersonal communication from physician and patient perspectives. The findings suggest once physicians adopt the use of an information prescription, they perceive they are providing an additional clinical service that enhances patient education and interpersonal communication. For physicians, participation in information prescription may improve patient communication, encourage information seeking, and lessen the number of poor quality Internet searches that patients frequently self-perform and bring to a doctor's office. Similarly, once patients receive a recommendation from a physician to seek health information on the web, patients may be more comfortable with health seeking on the Internet and discussing their findings with their doctor. The conclusions of the two evaluation studies imply an Information Prescription fosters a dialogue between providers and patients, helps patients use the Internet more effectively and seems to favorably impact patient education. As the medical community and patient advocacy groups continue to emphasize the importance of evidence-based information as the gold standard for accepted care, it can be expected that informatics tools such as Information Rx will come to play an increasingly important role as a vehicle to help identify and access high quality health information on the Internet.
The Ubiquitin-Proteasome Pathway and Its Role in Cancer (2005)

Critical cellular processes are regulated, in part, by maintaining the appropriate intracellular levels of proteins. Whereas de novo protein synthesis is a comparatively slow process, proteins are rapidly degraded at a rate compatible with the control of cell cycle transitions and cell death induction. A major pathway for protein degradation is initiated by the addition of multiple 76–amino acid ubiquitin monomers via a three-step process of ubiquitin activation and substrate recognition. Polyubiquitination targets proteins for recognition and processing by the 26S proteasome, a cylindrical organelle that recognizes ubiquitinated proteins, degrades the proteins, and recycles ubiquitin. The critical roles played by ubiquitin-mediated protein turnover in cell cycle regulation makes this process a target for oncogenic mutations. Oncogenes of several common malignancies, for example colon and renal cell cancer, code for ubiquitin ligase components. Cervical oncogenesis by human papillomavirus is also mediated by alteration of ubiquitin ligase pathways. Protein degradation pathways are also targets for cancer therapy, as shown by the successful introduction of bortezomib, an inhibitor of the 26S proteasome. Further work in this area holds great promise toward our understanding and treatment of a wide range of cancers.
Si Depth Profiles in Focused-Ion-Beam-Implanted GaAs (1985)

Depth distribution of implanted Si into GaAs using a focused-ion-beam (0.2 µm diameter, 160 keV) was profiled by means of differential Hall effect measurement and secondary ion mass spectroscopy. As compared to conventional unfocused-ion-beam implantation, implantation with a focused ion beam of high current density at high doses results in broadened profiles of the implanted Si at greater depths. This is probably caused by radiation-enhanced migration of the implanted Si during implantation.
Studies on Uracils: Synthesis of Novel Uracil Analogues via 1,5- and 1,6-Intramolecular Cycloaddition Reactions (1998)

6-(Tertiary amino)uracils 1 react with dimethyl acetylenedicarboxylate (DMAD) to afford 5,6-dihydropyrrolo[2,3-d]pyrimidines 3a and 3b and the tricyclic analogues 3c–fvia 1,5-electrocyclisation in excellent yields, whereas suitably functionalized uracil derivatives 5 undergo intramolecular 1,6-cycloaddition reactions to afford 5,6,7,8-tetrahydropyrido[2,3-d]pyrimidines 6a and 6b and the tricyclic analogues 6c–h in high yields.
Recurrent aphthous stomatitis. A study of the clinical characteristics of lesions in 93 cases (1991)

We studied the clinical characteristics of 93 patients with recurrent aphthous stomatitis (RAS); 66 corresponded to minor aphthae (MiRAS), 20 to major aphthae (MaRAS), and 7 to herpes-like ulcerations (HU). MiRAS was seen to present the lowest rate of recurrences, as well as the shortest duration and the fewest lesions per episode. In turn, MaRAS presented the longest duration per recurrence, along with a number of lesions and recurrences that was lower than in HU but greater than in cases of MiRAS. Finally, HU developed the greatest number of lesions and recurrences. When we classified RAS according to the rate of episodes, no statistically significant differences were observed among the three types in terms of patient age, number and duration of lesions, or evolution time of the oral disorder.
Experiencing and handling the diversity in data density and environmental locality in an indoor positioning service (2014)

Diversity in training data density and environment locality is intrinsic in the real-world deployment of indoor localization systems and has a major impact on the performance of existing localization approaches. In this paper, through micro-benchmarks, we find that fingerprint-based approaches are preferable in scenarios where a dense database is available; while model-based approaches are the method of choice in the case of sparse data. It should be noted, however, that practical situations are complex. A single deployment often features both sparse and dense sampled areas. Furthermore, the internal layout affects the propagation of radio signals and exhibits environmental impacts. A certain number of measurement samples may be sufficient for one part of the building, but entirely insufficient for another. Thus, finding the right indoor localization algorithm for a given large-scale deployment is challenging, if not impossible; there is no one-size-fits-all indoor localization approach.
Inside the Java Virtual Machine (1997)

From the Book:
My primary goal in writing this book was to explain the Java virtual machine-and several core Java APIs closely related to the virtual machine-to Java programmers. Although the Java virtual machine incorporates technologies that have been tried and proven in other programming languages, prior to Java, many of these technologies had not yet entered into common use. As a consequence, many programmers will encounter these technologies for the first time as they begin to program in Java. Garbage collection, multi-threading, exception handling, dynamic extension---even the use of a virtual machine itself-might be new to many programmers. The aim of this book is to help programmers understand how all these things work, and in the process we hope to help them become more adept at Java programming.
Another goal I had in mind as I wrote this book was to experiment a bit with the changing nature of text. Web pages have three interesting characteristics that differentiate them from paper-based text: they are dynamic (can evolve over time), they are interactive (especially if you embed Java applets in them), and they are interconnected (you can easily navigate from one to another). Besides the traditional text and figures, this book includes several Java applets (in a mini-Web site on the CD-ROM) that serve as interactive illustrations of the concepts presented in the text. In addition, I maintain a Web site at art ima. com on the Internet that serves as a launching point for readers to find more (and more current) information about the topics covered in the book. This book is composed of all of these components: text, figures, interactive illustra. tions, and constantly evolving links tofurther reading.
Simple 1-D image enhancement for head-mounted low vision aid (1999)

AbstractHigh-contrast binary images (black and white without shades of gray) were demonstrated to improve face recognition performance by the visually impaired using static images (Peli et al., Invest Ophthalmol Vis Sci 1991;32:2337-2350). A binary head-mounted display device has now been adapted to present video in real time for testing as a low vision mobility aid (an electronic telescope). When used for text presentation (as a head-mounted CCTV), a single threshold produces satisfactory performance. However, binarization of a video signal through a single threshold results in high-contrast but extremely poor image detail. A more detailed binary image can be obtained by applying bandpass filtering prior to thresholding. The application of the adaptive 2-D enhancement technique used by the DigiVision device enables such live bandpass processing and provides substantial improvement. To reduce the cost, weight, and power consumption of a portable low vision aid, a one dimensional (1-D) analog video processing alternative has been designed and implemented. Since the processing is applied only across the horizontal dimension, it provides no enhancement of horizontal features in the image. However, in this head-mounted camera application the user can easily resolve such details by a slight tilt of the head. The 1-D enhancement alternative provides satisfactory quality, high-contrast binary imaging at substantial savings.

The visualization of hepatic vasculature by X-ray micro-computed tomography (2006)

In this study, X-ray micro-computed tomography (CT) was used to reconstruct the fine structure macro- and microvasculature in three dimensions in contrast-enhanced rat liver samples. The subsequent application in the experimental CC531s colorectal cancer model was concurrent with results obtained from confocal microscopy in earlier studies. The en bloc stains osmium tetroxide in combination with uranyl acetate provided an excellent contrasting result for hepatic tissue after a trial of several contrasting agents. X-ray micro-CT allowed us to image the large blood vessels together with the branching sinusoids of hepatic tissue in three dimensions. Furthermore, interruption of the microvasculature was noted when rats were injected with CC531s colorectal cancer cells indicating the presence of hepatic metastases.
DEVELOPMENT AND ANALYSIS OF INPUT‐OUTPUT RELATIONS FOR IRRIGATION WATER (1967)

Recent developments in climatology mean that economists now have a highly acceptable physical theory which can underlie their analysis of the economic aspects of water as an input to the production process, as a source of production instability, and as a major component of error in their estimated crop production functions. This paper presents a model and a procedure for synthesising and analysing irrigation water crop input output relations based on this theory. The importance of time of application of water as well as quantity is shown. Different frequencies of irrigation are optimal at different times of the growing season.
Tamoxifen and Thromboembolism (1980)

<h3>To the Editor.—</h3> We question the safety of using tamoxifen citrate for patients with a known predisposition to thrombosis. This antiestrogen has been shown to be an effective hormonal agent in metastatic breast cancer, and so far, few serious side effects have been associated with its use. However, deep-vein thrombosis and pulmonary emboli have occurred in patients taking tamoxifen,<sup>1-3</sup>and it is possible that this could be related to its paradoxical estrogenic effects. <h3>Report of a Case.—</h3> A 72-year-old woman with metastatic pleural effusion and bone disease from breast cancer showed development of occlusion of the right brachial and ulnar arteries while she was receiving chemotherapy. A successful thromboembolectomy was performed. There was no obvious cardiac cause of embolism. A year later her disease progressed despite changes in chemotherapy. Estrogen receptor status was unknown. Tamoxifen citrate therapy, 10 mg twice daily, was started but was discontinued after a month
A novel pyrolyzed polyacrylonitrile-sulfur@MWCNT composite cathode material for high-rate rechargeable lithium/sulfur batteries (2011)

A novel pPAN-S@MWCNT core-shell composite material is prepared via in situpolymerization of acrylonitrile on the surface of MWCNT, mixing with sulfur and final pyrolysis. The homogenous dispersion and integration of MWCNT in the composite create an electronically conductive network and reinforce the structural stability, leading to the outstanding electrochemical performances as a cathode material for rechargeable lithium/sulfur batteries.
Quinazolinone Derivatives as Orally Available Ghrelin Receptor Antagonists for the Treatment of Diabetes and Obesity (2007)

The peptide hormone ghrelin is the endogenous ligand for the type 1a growth hormone secretagogue receptor (GHS-R1a) and the only currently known circulating appetite stimulant. GHS-R1a antagonism has therefore been proposed as a potential approach for obesity treatment. More recently, ghrelin has been recognized to also play a role in controlling glucose-induced insulin secretion, which suggests another possible benefit for a GHS-R1a antagonist, namely, the role as an insulin secretagogue with potential value for diabetes treatment. In our laboratories, piperidine-substituted quinazolinone derivatives were identified as a new class of small-molecule GHS-R1a antagonists. Starting from an agonist with poor oral bioavailability, optimization led to potent, selective, and orally bioavailable antagonists. In vivo efficacy evaluation of selected compounds revealed suppression of food intake and body weight reduction as well as glucose-lowering effects mediated by glucose-dependent insulin secretion.
Demonstration of various low group velocity effects in photonic crystal line defect waveguides by laser oscillation (2005)

In this work, waveguide modes were investigated in a two-dimensional photonic crystal slab, which lie above light line, from the point of view of the low group velocity. Low group velocity effects other than usual distributed feedback (DFB) were demonstrated as Fabry-Perot lasing oscillation in the short cavity length of 70 /spl mu/m.
Image formation in a fiber-optical confocal scanning microscope (1991)

Theoretical studies on image formation in a confocal scanning microscope with optical fibers as the transmission medium are reported. Theoretical analyses show that this new kind of microscope can be considered a coherent imaging system, even for finite fiber spot size. Based on these studies the coherent transfer functions in both in-focus and defocused cases are derived and calculated. The axial coherent transfer functions are also obtained, and, furthermore, the optical-sectioning property of the microscope system is investigated with the consideration of the image formation of a perfect-reflection planar object and a point object.
Novel Tear Interferometer Made of Paper for Lipid Layer Evaluation (2014)

We could successfully obtain photographs of the lipid layer pattern with this novel interferometer without additional equipment or cost. This interferometer may be useful for research regarding the pathophysiology, diagnosis, and treatment of dry eye.
Grey image enlargement with edge enhancement (2008)

In a previous paper, we presented an image enlargement approach based on the grey polynomial interpolation (GPI) [11]. In this paper, we propose an edge enhancement scheme to improve the enlarged image by the GPI. The proposed approach is called GPI/EE (GPI with edge enhancement). Basically, the edge enhancement consists of two stages. First, the edge in the enlarged image is enhanced by Laplacian filter. This doing relieves the blur in the enlarged image. Next, the zigzag edge in the image after Stage 1 is solved by smoothing neighborhood pixels around edges which are located by Canny edge detector. Examples are provided to justify the GPI/EE approach. Simulation results indicate that the enlargement image obtained by GPI/EE has better visual quality than that by GPI in the given examples.
Evaluation of a Mycoplasma gallisepticum Strain Exhibiting Reduced Virulence for Prevention and Control of Poultry Mycoplasmosis (1992)

Two experiments were conducted to evaluate the virulence and vaccination efficacy of a Mycoplasma gallisepticum (MG) isolate designated MG Intervet 6/85. Virulence of the strain was determined by evaluation of airsacculitis scores following aerosol exposure to the isolate before and after 10 sequential passes in either commercial broiler chickens or commercial turkeys. Two-week-old specific-pathogen-free chickens were vaccinated by aerosol exposure. The birds were challenged with the R' strain of MG at either 4 or 8 weeks post-vaccination. Efficacy was evaluated by airsacculitis scores determined 21 days after challenge. Ten repetitive back-passes of the isolate in chickens and turkeys did not substantially increase the virulence. Virulence for both chickens and turkeys was minimal, while protection elicited by aerosol vaccination in young chickens against virulent R' strain was significant (P less than or equal to 0.05) compared with unvaccinated controls.
Varactor Tuned Microwave Filters (2005)

Optically Patternable Polymer Films as Model Interfaces to Study Cellular Behaviour on Topographically Structured Materials (2010)

We assessed blood interaction with different micrometer-scale topographies under flow conditions using a micro-fluidic array system. The channels of the micro-fluidic array chip were coated with azobenzene polymer films, which were then topographically structured using a one-step non-contact optical technique. A set of surfaces with different topographies was produced varying laser irradiation duration. These surfaces were then exposed to blood flow. The blood flow rate was measured with a micro-channel array flow analyzer. The measured blood flow rates decreased with time for all the samples, indicating formation of platelet clots which obstruct the channels during flow. This effect appeared enhanced on polymer surfaces having a sinusoidal profile with 200-nm-high ridges and 1.2-μm-grating spacing. The morphology of platelets that adhered on the polymer films was studied by scanning electron microscopy. Platelets adhered on azobenzene surfaces with flat topographies, typically exhibiting filopodia. Platelets adhered on optically structured surfaces also exhibited lamellipodia and appeared flattened on surfaces with the highest ridges. We conclude that surface topography influences blood behaviour on azobenzene polymer films.

Multilevel neural network system for EEG spike detection (2002)

The design and evaluation of an artificial neural network system for the detection of epileptogenic spikes is described. The system is composed of smaller neural network modules which are trained individually and organized in two levels. The first-level modules are trained to recognize candidate spikes in single referential electroencephalogram (EEG) channels. Original digitized data with a running window of 100 ms provided the input for the first-level modules. A second-level module is used for the spatial integration of 16 first-level modules. The system was trained and tested using clinical EEG data interpreted by four expert electroencephalographers. The results show that spikes can be recognized directly from unprocessed EEG and a second-level neural network can integrate spatial EEG information and eliminate false detections.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
