Optical tachometry for monitoring nuclear magnetic resonance sample spinning rates (1970)

A simple optical tachometer utilizing fibre optics and solid state electronics has been designed and constructed in order to monitor sample turbine spin speeds on a Varian HA 100D nuclear magnetic resonance spectrometer. By use of a bifurcated fibre optical path, light is transmitted to the turbine strobe, modulated, and returned to the detector within the same plastic-sheated glass fibre bundle. Rotational information can thus be retrieved without disturbing the magnetic field or sample environment. The relation of sample spinning speed to spectral quality is discussed.

Trauma-Induced Intention Tremor Relieved by Stereotaxic Thalamotomy (1966)

THIS DESCRIPTION of two cases of trauma-induced intention tremor relieved by thalamotomy serves to add to the list of those already reported and to further delineate the site of the pathologic lesion. The first case presented with intention tremor of the left extremities and paralysis of the right superior oblique ocular muscle. The second case presented with intention tremor of the right extremities and ataxia of gait. Report of Cases Case1.—This 51-year-old, right-handed Negro man had been in good general health, except for mild diabetes mellitus and previous heavy intake of alcohol until March 1965, when he fell down five steps, striking the ulnar aspect of his left forearm and jolting his entire body. There was no loss of consciousness. During the succeeding days he noted some clumsiness of his left arm. About three weeks later the clumsiness became more severe and thereafter progressed so that he had
Process challenges in low-k wafer dicing (2004)

Rapid developments in semiconductor industry and the need to maintain interconnect performance as feature sizes shrink are driving a transition to low dielectric constant (k) materials. The very different chemistries and materials properties of low-k dielectric materials may impose novel challenges to wafer/chip manufacturing and packaging processes. Process integration thus becomes more difficult due to the profound changes in properties compared with traditional dielectric materials. Dicing (or sawing) is the first step in the packaging process and its quality can have a significant impact on yields, as well as on device reliability. This paper describes dicing of eight types of Spin-On and CVD low-k wafers. Effects of various blades and dicing process parameters, as well as their combined effect on quality and yield, are discussed. In addition, the effect of cut depth is also examined. Various problems encountered in low-k wafer dicing are presented, and considerations and potential solutions for overcoming these quality obstacles in low-k wafer dicing are discussed. The study shows that the optimized dicing processes must be based on the actual low-k materials, wafer structures and process history of the low-k wafers.
Giving up logical atomism? Some remarks on Wittgenstein’s Some remarks on logical form (1929) (2013)

Estruturas elementares (atômicas) e complexas podem ser caracterizadas tanto em relação a sua composição quanto em relação a sua decomposição. (a) as regras para (de-)compor estruturas elementares não são recursivas. (b) As regras para (de-)compor estruturas complexas são comumente condicionadas e recursivas. Ao usar esta diferenciação quatro aspectos do atomismo lógico do Tractatus de Wittgenstein são discutidos: fatos (atômicos), proposições elementares, objetos/nomes e regras de substituição. Considerando estes aspectos nós investigamos as modificações de sua posição em relação ao atomismo lógico em Some Remarks on Logical Form. Contra a posição de Wittgenstein as consequencias de se usar funções de verdade dentro de proposições atômicas são analisadas. Finalmente, nós discutimos analogias entre a exclusão de proposições atômicas descrevendo posições das pecas de xadrez em um tabuleiro. A exclusão mútua de descrições é relacionada à estrutura do espaço lógico relativo às regras básicas do jogo. Estas considerações indicam um possível caminho para o conceito de jogos de linguagem na Filosofia tardia de Wittgenstein.

Overview of the SpiNNaker System Architecture (2012)

SpiNNaker (a contraction of Spiking Neural Network Architecture) is a million-core computing engine whose flagship goal is to be able to simulate the behavior of aggregates of up to a billion neurons in real time. It consists of an array of ARM9 cores, communicating via packets carried by a custom interconnect fabric. The packets are small (40 or 72 bits), and their transmission is brokered entirely by hardware, giving the overall engine an extremely high bisection bandwidth of over 5 billion packets/s. Three of the principal axioms of parallel machine design (memory coherence, synchronicity, and determinism) have been discarded in the design without, surprisingly, compromising the ability to perform meaningful computations. A further attribute of the system is the acknowledgment, from the initial design stages, that the sheer size of the implementation will make component failures an inevitable aspect of day-to-day operation, and fault detection and recovery mechanisms have been built into the system at many levels of abstraction. This paper describes the architecture of the machine and outlines the underlying design philosophy; software and applications are to be described in detail elsewhere, and only introduced in passing here as necessary to illuminate the description.
Peripheral inflammation selectively increases TRPV1 function in IB4-positive sensory neurons from adult mouse (2005)

C-fiber nociceptors can be divided into two groups based on growth factor dependency and isolectin B4 (IB4) binding. IB4-negative nociceptors have been proposed to contribute to inflammatory pain. Since the TRPV1 receptor is critical for inflammatory heat hyperalgesia, we hypothesized that inflammation would sensitize IB4 negative but not IB4-positive small-diameter neurons to TRPV1 stimuli. Two days after complete Freund's adjuvant (CFA)-induced inflammation in the hind paw of mice, lumbar 4/5 ganglia were dissociated and small-diameter (</=26 microm) neurons were quantified for responsiveness to the TRPV1 agonists, capsaicin and protons using patch clamp recordings. Surprisingly, inflammation did not alter the responsiveness of IB4-negative neurons to capsaicin or protons. Conversely, inflammation increased the percentage of IB4-positive neurons that responded to 1 microM capsaicin from 24 to 80% and increased the percentage that responded to pH 5.0 from 54 to 85%. In parallel, inflammation increased the percentage of IB4-positive neurons that was TRPV1-immunoreactive. The inflammation-induced increase in capsaicin- and proton-responsiveness was entirely mediated by TRPV1 because IB4-positive neurons from inflamed TRPV1-/- mice were capsaicin-insensitive and unaltered in proton-responsiveness. Interestingly, comparison of neurons from TRPV1+/+ and TRPV1-/- mice revealed that the sustained proton-evoked currents in IB4-positive neurons were independent of TRPV1 whereas the sustained-only proton currents in IB4-negative neurons were TRPV1-dependent. Together, these data indicate that TRPV1 function and expression are selectively increased in IB4-positive neurons during inflammation in mouse and suggest a novel role for IB4-positive C-fibers during inflammation.
Production of poly(3-hydroxybutyrate) [P(3HB)] with high P(3HB) content by recombinant Escherichia coli harboring the Alcaligenes latus P(3HB) biosynthesis genes and the E-coli ftsZ gene (1999)

Filamentation-suppressed recombinant Escherichia coli strain harboring the Alcaligenes latus polyhydroxyalkanoate (PHA) biosynthesis genes and the E. coli ftsZ gene was constructed and cultivated for the production of poly(3-hydroxybutyrate) [P(3HB)] with high concentration and high content. By the pH-stat fed-batch culture of this recombinant E. coli strain XL1-Blue(pJC5), the final cell concentration and P(3HB) concentration obtained in 44.25 h were 172.2 g cell dry weight/l and 141.9 g P(3HB)/l, respectively, resulting in productivity of 3.21 g P(3HB)/l-h. More importantly, the P(3HB) content obtained was 82.4 wt %, which was significantly higher than that obtained with the recombinant E. coli harboring only the PHA biosynthesis genes.
The relationship between AGT self‐description and significant life events: A longitudinal study (1977)

BACKGROUND: Non-use of and dissatisfaction with ankle foot orthoses (AFOs) occurs frequently. The objective of this study is to gain insight in the conversation during the intake and examination phase, from the clients’ perspective, at two levels: 1) the attention for the activities and the context in which these activities take place, and 2) the quality of the conversation.<br/>METHODOLOGY: Semi-structured interviews were performed with 12 AFO users within a two-week period following intake and examination. In these interviews, and subsequent data analysis, extra attention was paid to the needs and wishes of the user, the desired activities and the environments in which these activities take place.<br/>RESULTS AND CONCLUSION: Activities and environments were seldom inquired about or discussed during the intake and examination phase. Also, activities were not placed in the context of their specific environment. As a result, profundity lacks. Consequently, orthotists based their designs on a ‘reduced reality’ because important and valuable contextual information that<br/>might benefit prescription and design of assistive devices was missed. A model is presented for mapping user activities and user environments in a systematic way. The term ‘user practices’ is introduced to emphasise the concept of activities within a specific environment.
Stability of Phenylephrine Hydrochloride Nasal Drops (1972)

The stability of a 0.5% solution of phenylephrine hydrochloride containing methylparaben (0.02%) and propylparaben (0.01%) as preservatives and sodium bisulfite (0.1%) as an antioxidant was investigated. Stability tests were conducted at room temperature and using five different pH values (5,6,7,8 and 9) for a period of 540 days. The percent retention of potency was determined using two different colorimetric methods, one for the hydroxyphenol moiety and the other for the secondary amino group on the side chain of phenylephrine. Phenylephrine hydrochloride nasal drops appeared to be very stable at all pH values. In 540 days, the nasal drops which were buffered at pH 5 and 6 did not discolor appreciably. At higher temperatures (40 and 60 C) similar solutions discolored in less than 30 days and therefore were not studied quantitatively. In order for the drops to be stable both chemically and physically, an expiration period of 18 months is suggested provided that the pH is between 5 to 6.
An Improved Preparation of 4,7-Phenanthrolino-5,6:5′,6′-pyrazine (1996)

[A study on hepatic perfusion parameter calculation]. (2013)

Hepatic perfusion parameters play an important role in detecting and diagnosing diffusion diseases of liver. Based on a hemodynamic model. In this study, we described a fast and accurate method to calculate the perfusion parameters. First, we used a dual-input one-compartment kinetics model to illustrate the distribution of the contrast agent concentration among the body. Then, we used the Gaussian function to fit the scatter concentration data of portal vein and aorta, to obtain a liver agent concentration on function of time. Finally, we solved the model parameters by using Levenberg-Marquardt algorithm, and calculated the perfusion parameters. The results showed that the method proposed in this study could calculate the parameters precisely, and had a prosperous future application possibility.
An international evaluation of the cancer-preventive potential of nonsteroidal anti-inflammatory drugs. (1997)

The IARC convened a Working Group of experts in Lyon, France, on April 2-8, 1997 to evaluate the cancer-preventive activity of four nonsteroidal anti-inflammatory drugs (aspirin, sulindac, piroxicam, and indomethacin). Epidemiological observational studies of aspirin that differed in design, location, population, and motivating hypothesis have consistently shown that regular use lowers the risk for colorectal cancer by up to 50%; however, the one randomized trial did not show protection by aspirin. Definite evidence of chemopreventive activity normally requires data from appropriately designed randomized trials. The strength of the scientific evidence that aspirin prevents colorectal cancer in humans was thus considered to be limited. In animal models, there was sufficient evidence that aspirin prevented against cancer. Aspirin and aspirin-like drugs may have an important adverse side effects, the most frequent of which are gastrointestinal disturbances ranging in severity from dyspepsia to peptic ulcer. Given the remaining uncertainties in the preventive effect and the risk of adverse side effects, detailed consideration of the total benefits and of toxicity will be required before widespread use of aspirin for the prevention of colorectal cancer can be recommended. Sulindac shows promise in reducing the number and size of adenomatous polyps in patients with familial adenomatous polyposis. Further research is required, however, to determine whether and to what extent the risk for colorectal cancer in such patients is reduced. In people without familial adenomatous polyposis, there is inadequate evidence that sulindac has cancer-preventive activity. Fewer data were available on piroxicam and indomethacin than on aspirin and sulindac. Although these drugs consistently prevent colorectal cancers in experimental animal models, the evidence that they prevent colorectal cancer in humans was considered to be inadequate. The results of the meeting, including recommendations for future research, will be published as Volume 1 of the IARC Handbooks of Cancer Prevention.
Electronic error reporting via Internet in the VAX environment (1995)

Describes an electronic OCLC error reporting (OER) program developed at the Albert B. Alkek Library, Southwest Texas State University, in response to the OCLC announcement that OCLC users could begin submitting bibliographic record change requests and duplicate record reports via Internet e‐mail. OER is a menu‐driven program written in VAX VMS which facilitates sending OCLC error reports by providing blank error‐report forms for various error‐reporting activities. This is accomplished by adding constant and system‐supplied information to the forms and then automatically sending the forms, while giving ample opportunities to review the accuracy of the outgoing report. Doing so provides more uniformity and accuracy in the reporting process and saves money and staff time. Suggests that, although the program is written for the SWT library, it may easily be modified and used by other compatible institutions.
An adaptation of the interior point method for solving the global routing problem (1991)

A linear-programming (LP) solution technique is applied to solve the global routing problem. Minimal spanning trees that were found in the subgrid by generating vertical and horizontal lines about the points of a given net and a modified interior point approach that reduces the number of arc constraints which were considered in the routing problem were used to reduce the problem site. An interior point algorithm approach is developed to solve the resulting LP problem. A FORTRAN code ROUTFAST is tested on several problems of varying arc capacities. ROUTFAST is compared with MINOS 5.0 which is a Simplex-based code on the same set of problems. ROUTFAST is at least 8-20 times faster than MINOS on the largest problems tested and seems to be getting faster as the problem size and arc capacity increases. Using a modification (ROUTLP) to solve four benchmark gate-array layout problems, ROUTFAST yielded competitive global routing results to TimberWolfSC Version 5.4 and in a fraction of TimberWolfSC's running time.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Expression of p53 and Lactate Dehydrogenase in Murine Fibrosarcoma Following Exposure to g-Radiation (2001)

Radiation-induced alterations in the levels of p53 and lactate dehydrogenase activities were studied in fibrosarcoma, following exposure to different doses of gamma-irradiation (2-10 Gy). The levels of p53 were elevated in the cytoplasm, while the lactate dehydrogenase activity in tumor tissue was considerably decreased.
Determination of Nitrate and Nitrite Content of Dietary Supplements Using Ion Chromatography (2014)

Following the discovery of nitrite and nitrate as pro-drugs of the vasorelaxant nitric oxide, many studies have reported enhanced athletic performance following intake of these ions either intravenously or as a food supplement. The primary aim of this study was to develop a new accurate, reliable and robust ion chromatography based method. The newly developed method was applied to selected foodstuffs in powdered and/or juice form to measure levels of nitrate and nitrite. In addition to the commonly used beetroot juice, an initial HPLC-based screen of a range of foods identified spinach powder with very high nitrate and nitrite content. As a result of the initial screening, branded beetroot juice, concentrated beetroot juice and spinach powder were analysed using a new extraction method followed by a newly developed and validated ion chromatographic determination of nitrate and nitrite levels. The new ion chromatography based assay showed higher efficiency and better recovery than the HPLC approach. Significant inter-batch variations were found in levels of nitrate and nitrite in the beetroot juice and concentrated beetroot juice samples tested. In contrast spinach powder could provide a homogenous source of nitrate and nitrate for physiological studies. In summary, the new assay is rapid and efficient facilitating rigorous analyses of nitrate and nitrite levels prior to investigations requiring intake of foodstuffs containing these nitric oxide precursors.
Performance Optimization of Nyquist Signaling for Spectrally Efficient Optical Access Networks [Invited] (2014)

In this work, Nyquist pulse-shaping technology is exploited for future implementations of optical access networks. The paper first presents technical issues regarding digital implementation of Nyquist spectral shaping for low-symbol-rate systems. Second, the potential benefits regarding mitigation of cross talk (linear and nonlinear) of Nyquist pulse shaping in symmetric and bidirectional wavelength-division multiplexing passive optical networks (WDM-PONs) are presented. Lastly, the paper proposes a WDM-PON solution employing self-coherent detection at the optical network unit and heterodyne coherent detection at the optical line terminal. In this proposed architecture, a multi-objective optimization strategy is developed to enhance the transmission performance of the Nyquist-shaped bands in full-duplex mode.
Right Hemifield Deficits in Judging Simultaneity: A Perceptual Learning Study (2012)

Introduction: Right visual field (RVF) deficits have been demonstrated for several temporal vision tasks (Newman & Albino, 1977, 1979; Verleger et al., 2009; Smigasiewicz et al., 2010; Kelly & Matthews, 2011). Here, we combined signal detection theory and perceptual learning to provide new information about why and when (e.g., the visual information stage at which) RVF deficits arise in simultaneity judgments. Method: Twenty-two Denison University undergraduates judged whether peripheral Gabor targets changed orientation simultaneously versus asynchronously, and in separate blocks, whether those targets were the same or different in spatial frequency. Retinal stimulation was identical on the simultaneity and spatial frequency tasks. Trials containing RVF Gabor targets were blocked separately from LVF-Gabor-target trials. In experiment 1, we evaluated selective attention’s effects by randomly interleaving trials on which Gabor distractors either appeared contralateral to the targets or were absent. In experiment 2, participants completed seven perceptual learning sessions requiring RVF simultaneity judgments on the above-described stimuli. Results: (Experiment 1) When attention was not needed to exclude distractors, signal detection theory analyses revealed a significant RVF simultaneity deficit with error patterns implicating low RVF temporal acuity, not excessive RVF neural noise. Adding attentionally demanding distractors introduced a separate, significant RVF simultaneity deficit with error patterns implicating the inappropriate integration of temporal asynchronies from distractor locations. Neither the distractor-independent RVF acuity deficit nor the distractor-induced RVF excessive spatial integration occurred for spatial frequency discrimination at the same retinal locations. (Experiment 2) Our perceptual learning procedure significantly improved RVF simultaneity judgments. The learning was task-specific but generalized to the untrained (left) visual field and to novel retinal locations. Conclusion: Our findings suggest that the RVF deficit in judging simultaneity reflects low temporal acuity and excessive spatial integration –rather than excessive neural noise– at the visual information stage responsible for the simultaneity decision.

NOTE ON CAHEN′S INTEGRAL FORMULAS (2002)

We present an explicit form for a class of definite integrals whose special cases include some definite integrals evaluated, over a century ago, by Cahen who made use of an appropriate contour integral for the integrand of a well-known integral representation of the Riemann Zeta function given in (3). Furthermore another analogous class of definite integral formulas and some identities involving Riemann Zeta function and Euler numbers En are also obtained as by-products.
