Modular components for an optical array logic system (1987)

On the basis of modularization of an optical parallel array logic system (OPALS), a new concept of an optical digital computer is considered. The OPALS is a parallel digital optical computing system using optical array logic capable of executing parallel neighborhood logical operations, or cellular logic. Modularizing functional elements in the OPALS, stability, reliability, and flexibility of the system can be improved. Performance of the modularized OPALS is estimated.
A modified Holland machine (1963)

A highly parallel machine is, in concept, a multiprocessor with more than one hundred semi-independent, program-controlled computing elements. One type of highly parallel machine is the parallel-network computer, wherein the computing elements are arranged in a geometrical array and direct communication among elements is restricted for each to a local neighborhood. (See Section II.) Most of the postulated network systems have a separate central control unit that directs the operation of the network. Examples of such are Unger's machine (References 17 and 18), McCormick's machine (References 5 and 13), and SOLOMON (References 1, 14, and 15). The only published example of a network machine without central control is that proposed by Holland (References 4, 9, 10, and 16), and is the organization to be considered here.
High-density lipoprotein cholesterol measurements. A help or hindrance in practical clinical medicine? (1986)

Often, plasma high-density lipoprotein cholesterol (HDLC) measurements lack sufficient accuracy to be of practical use in an individual clinical setting. Recent clinical investigations have demonstrated the strong predictive value of HDLC concentration for future coronary events and rate of progression of angiographically assessed coronary atherosclerosis. Clinical demand for HDLC measurements by clinicians has increased after the announcements of these results. The ability of clinical laboratories to assess HDLC values accurately, so that they may be applied on an individual basis, may be lacking, and enhanced accuracy should be encouraged.

Breitbandige Ausbreitungsmessungen zur Charakterisierung des Funkkanals beim GSM-System (1991)

The performance of a mobile radio communication system is strongly affected by the characteristics of the radio channel. For measurement of the time-variant impulse response of the mobile radio channel a measurement setup was developed having a bandwidth matched to the GSM system. A signal analysis using adaptive noise suppression allows for the extraction of parameters relevant to the GSM system. Different propagation conditions are characterized by different shapes of the impulse response as well as different Doppler spectra
Representing partial ignorance (1996)

This paper advocates the use of nonpurely probabilistic approaches to higher-order uncertainty. One of the major arguments of Bayesian probability proponents is that representing uncertainty is always decision-driven and as a consequence, uncertainty should be represented by probability. Here we argue that representing partial ignorance is not always decision-driven. Other reasoning tasks such as belief revision for instance are more naturally carried out at the purely cognitive level. Conceiving knowledge representation and decision-making as separate concerns opens the way to nonpurely probabilistic representations of incomplete knowledge. It is pointed out that within a numerical framework, two numbers are needed to account for partial ignorance about events, because on top of truth and falsity, the state of total ignorance must be encoded independently of the number of underlying alternatives. The paper also points out that it is consistent to accept a Bayesian view of decision-making and a non-Bayesian view of knowledge representation because it is possible to map nonprobabilistic degrees of belief to betting probabilities when needed. Conditioning rules in non-Bayesian settings are reviewed, and the difference between focusing on a reference class and revising due to the arrival of new information is pointed out. A comparison of Bayesian and non-Bayesian revision modes is discussed on a classical example.
CuZn-superoxide dismutase, Mn-superoxide dismutase, catalase and glutathione peroxidase in pancreatic islets and other tissues in the mouse (1981)

Exogenous superoxide dismutase, catalase and scavengers of the hydroxyl radical protect pancreatic-islet cells against the toxic actions of alloxan in vitro [Grankvist et al. (1979) Biochem. J. 182, 17--25]. To test whether the extraordinary sensitivity of islet cells to alloxan is due to a deficiency of endogenous enzymes protecting against oxygen-reduction products, we assayed CuZn-superoxide dismutase, Mn-superoxide dismutase, catalase and glutathione peroxidase in mouse islets and other tissues. To correct for any blood contamination, haemoglobin was also measured in the tissue samples. Pancreatic islets were found to belong to tissues with relatively little activity of the protective enzymes. However, the deviation from other tissues in this respect is probably not large enough to explain the especially great susceptibility of islet cells to alloxan.
Determination of Fluorescence-Labeled Asparaginyl-Oligosaccharide in Glycoprotein by Reversed-Phase Ultraperformance Liquid Chromatography with Electrospray Ionization Time-of-Flight Mass Spectrometry (2007)

Eight fluorescence reagents, i.e., DBD-F, NBD-F, DNS-Cl, NDA, PSC, FITC, Fmoc-Cl, and DMEQ-COCl, which are reactive to an amino functional group, were tested for the labeling of asparaginyl-oligosaccharides in a glycoprotein. Although the optimal reaction conditions and the fluorescence maximal wavelengths were different for each reagent, the highly sensitive fluorescence detection at the femtomole level of Disialo-Asn (a representative asparaginyl-oligosaccharide) was obtained from the labeling utilizing these reagents. Among them, PSC was the most reliable reagent in terms of detection sensitivity (approximately 3 fmol, signal-to-noise ratio of 5 (S/N = 5) on the chromatogram). However, the structural information could not be obtained from the fluorescence detection. Thus, the on-line determination of a real sample was carried out by UPLC-ESI-TOF-MS. The detection limit of the PSC-labeled Disialo-Asn by selected-ion chromatography was 58 fmol (S/N = 5). When the proposed procedure was applied to the determination of oligosaccharides in ovalbumin, 15 species of PSC-labeled oligosaccharides possessing Man, GlcNAc, and Gal units were identified from the UPLC-ESI-TOF-MS. The number of identified oligosaccharides was relatively greater than the method using Fmoc-Cl. Based on the ovalbumin results, the proposed labeling with PSC followed by UPLC-ESI-TOF-MS detection seems to be useful for the on-line asparaginyl-oligosaccharide analysis.
Long-Term Therapy to Prevent Stroke (2005)

Cerebrovascular disease is the third leading cause of mortality and the leading cause of long-term neurological disability in the United States. Most strokes are of ischemic origin and, other than cardioembolic or small vessel strokes, are caused by the development of platelet-fibrin thrombi on an atherosclerotic plaque. This underlying disease mechanism shares important features with coronary artery disease and peripheral artery disease, highlighting the systemic nature of atherothrombosis and the elevated cross risk in stroke patients for ischemic events in other vascular beds. It has been estimated that up to 80% of ischemic strokes could be prevented with application of currently available treatments for blood pressure, cholesterol, and antithrombotic therapies. Stroke is not, like cancer, waiting for a scientific breakthrough; stroke preventive treatments are well understood and widely available. It is only the application of these treatments to patients, many of whom do not visit physicians, that is lacking. Clearly, better education of the public and active participation of primary care physicians is essential to get the message out to all those at risk.

How to measure CMB power spectra without losing information (1997)

A new method for estimating the angular power spectrum ${C}_{l}$ from cosmic microwave background (CMB) maps is presented, which has the following desirable properties. (1) It is unbeatable in the sense that no other method can measure ${C}_{l}$ with smaller error bars. (2) It is quadratic, which makes the statistical properties of the measurements easy to compute and use for estimation of cosmological parameters. (3) It is computationally faster than rival high-precision methods such as the nonlinear maximum-likelihood technique, with the crucial steps scaling as ${n}^{2}$ rather than ${n}^{3}$, where $n$ is the number of map pixels. (4) It is applicable to any survey geometry whatsoever, with arbitrary regions masked out and arbitrary noise behavior. (5) It is not a ``black-box'' method, but quite simple to understand intuitively: it corresponds to a high-pass filtering and edge softening of the original map followed by a straight expansion in truncated spherical harmonics. It is argued that this method is computationally feasible even for future high-resolution CMB experiments with $n\ensuremath{\sim}{10}^{6}$--${10}^{7}$. It is shown that ${C}_{l}$ computed with this method is useful not merely for graphical presentation purposes, but also as an intermediate (and arguably necessary) step in the data analysis pipeline, reducing the data set to a more manageable size before the final step of constraining Gaussian cosmological models and parameters --- while retaining all the cosmological information that was present in the original map.
The Effect of Thalamotomy on the Progress of Unilateral Parkinson's Disease (1970)

LTHOUGH tremor and rigidity are frequently unilateral at the onset of Parkinson's disease, these signs usually spread to the opposite side of the body. Certain patients with unilateral tremor and rigidity, however, appear to be cured by successful thalamotomy. Cooper 1 has proposed alternative hypotheses to explain the effect of thalamic surgery in these patients: 1) a thalamotomy that permanently abolishes unilateral tremor and rigidity prevents spread to the opposite side of the body by interrupting the pathways in the basal ganglia subserving the propagation of the disease process; or 2) thalamotomy has no effect on the progress of tremor and rigidity to the opposite side of the body, and those patients with unilateral tremor and rigidity who appear to be cured by successful surgery have a benign form of Parkinson's disease. To study these hypotheses, we examined 72 patients approximately 5 years after they had undergone cryosurgical ventrolateral thalamotomy for tremor and rigidity which, at the time of surgery, were confined to one side of the body. Material and Methods For the purposes of this study, unilateral Parkinson's disease was defined as tremor and rigidity confined to the extremities of one side of the body. Masked facies, balance disturbances, akinesia, and other vegetative signs of Parkinson's disease were not included in this definition. From the St. Barnabas Hospital neurosurgical files subsequent to January 1, 1963, we selected the first 100 patients whose tremor and rigidity were unilateral at the time of surgery. Each patient was then contacted to arrange an interview
Examination of natural gums as matrices for sustained release of theophylline. (1984)

Release patterns of theophylline from compressed tablets prepared from theophylline and various natural gums were examined. Carrageenan, locust bean gum, guar gum, gum tragacanth, and sodium alginate were tested. Release patterns of the drug from tablets prepared from a mixture of carrageenan and locust bean gum were more sustained than those from carrageenan tablets. Changes in release rates caused by changing the gum contents or drug-to-gum ratios were also examined.
Rat Calmodulin cDNA (1987)

We report the isolation of a clone encoding calmodulin from a rat brain cDNA library; genomic clones were also isolated and partially characterized. The derived amino acid sequence has 100% homology to the published mammalian protein sequences. In rat, we identify two major RNA species of approximately 2.2 and 0.75 kb in length by RNA blot analysis. Furthermore, the mRNA is highly enriched in brain tissue, compared to liver or kidney. A variant (GATAAA) of the putative poly(A) addition signal is observed at the 3' end of one of the mRNA species.
Depression, excessive alcohol consumption and nalmefene (2014)

It is common for people with low mood to drink alcohol to excess, thus setting up a cycle of worsening depression. It is well recognised that antidepressants are not a stand-alone treatment and that concurrent treatment to help the patient reduce or stop drinking is also required. This article describes how nalmefene, a relatively new drug which helps reduce alcohol comsumption, was used effectively in a woman with depression.
CloudTPS: Scalable Transactions for Web Applications in the Cloud (2010)

NoSQL Cloud data services provide scalability and high availability properties for web applications but at the same time they sacrifice data consistency. However, many applications cannot afford any data inconsistency. CloudTPS is a scalable transaction manager to allow cloud database services to execute the ACID transactions of web applications, even in the presence of server failures and network partitions. We implement this approach on top of the two main families of scalable data layers: Bigtable and SimpleDB. Performance evaluation on top of HBase (an open-source version of Bigtable) in our local cluster and Amazon SimpleDB in the Amazon cloud shows that our system scales linearly at least up to 40 nodes in our local cluster and 80 nodes in the Amazon cloud.
The Effect of Fuzzy Logic on Database (2009)

For many years, achieving unambiguous knowledge has been turned to a serious challenge for human being. From Aristotlepsilas introduction of two valued logic up to now, human being, through utilizing it, could achieve outstanding positions. Technology has grown up and still is getting more efficiency day by day. Contingenciespsila phenomena were among phrases that may be seen thoroughly in all science fields especially where systems have got complication or the numbers of observations increased. However, whatever contingencies were to follow had a distinct difference than ambiguous situations existed in the systems. In spite of emergence of random phenomena, scientists still believed that the only way of a systempsilas increasing efficiency is to increase precision. One of the related areas is about application of fuzzy systems theory on database, data retrieval & expert support systems, and knowledge base. These three areas are similar in many directions; however, there are some differences. Yet, the most important issue that is being considered in fuzzy database is how to encounter with phenomenon of uncertainty. There are many courses of action for solving this problem; hence, in this study we propose the most important approaches and existed solutions for fuzzy database modeling.
Human-environment process (1986)

Rogers' principle of integrality was examined through testing the hypothesis that healthy subjects who are confined to bed in a varied harmonic environment will perceive themselves to be more rested than those subjects confined to bed in quiet ambient environment. A two-group pretest-posttest design was used to gather data to test the hypothesis. The findings of the study revealed that the hypothesis was supported beyond the 0.05 level of significance. The integrity of the mutual human-environment field process was strengthened with an environment of varied harmonic sounds.

Migration of <i>Plasmodium</i> Sporozoites Through Cells Before Infection (2001)

Intracellular bacteria and parasites typically invade host cells through the formation of an internalization vacuole around the invading pathogen. Plasmodium sporozoites, the infective stage of the malaria parasite transmitted by mosquitoes, have an alternative mechanism to enter cells. We observed breaching of the plasma membrane of the host cell followed by rapid repair. This mode of entry did not result in the formation of a vacuole around the sporozoite, and was followed by exit of the parasite from the host cell. Sporozoites traversed the cytosol of several cells before invading a hepatocyte by formation of a parasitophorous vacuole, in which they developed into the next infective stage. Sporozoite migration through several cells in the mammalian host appears to be essential for the completion of the life cycle.

Characterization of monoclonal antibodies that define rat T cell alloantigens. (1983)

A panel of monoclonal antibodies with specificity for rat T cell alloantigens was prepared by somatic cell hybridization with the use of spleen cells from either BH (ART-1b, 2b) or NBR (ART-1b, 2a) rats immunized with LEW (ART-1a, 2a) thymus, spleen, or lymph node cells. Comparison of the antibodies resulted in three distinct patterns of complement-mediated cytotoxicity. Further comparison of four representative hybridoma antibodies with antisera having specificity for ART antigens by indirect immunofluorescence demonstrated that two of the three patterns corresponded to anti-ART-1a and anti-ART-2a specificities. The patterns of binding of the anti-ART hybridomas were shown to be different from those produced by mouse monoclonal antibodies having anti-leukocyte-common (L-C) or anti-Thy-1.1 activities as well as antibodies produced by the monoclonal W3/25, which detect a subpopulation of T lymphocytes. Functional studies performed in vitro with cells fractionated by treatment with the monoclonal anti-ART antibodies and complement showed the ART-1 determinant recognized by the hybridoma products BC 84A or BY 12.3 is expressed by mature cytolytic T lymphocytes (CTL) and by cells involved in the generation of CTL during MLR, but not plaque-forming cells. Together, the data suggest the antibodies BC 84A and BY 12.3 can be used to define rat T cell populations. To date, the functional significance of cell populations recognized by monoclonal antibodies having anti-ART-2a or anti-ART-3-like activities has not been determined.
Direct Coupled Resonator Filters Realized by Gap Waveguide Technology (2015)

Novel types of narrow band filters based on the newly introduced gap waveguide technology are presented in this paper. The proposed filters have a central frequency of 35 GHz with approximately 1% fractional bandwidth. The filter resonators are composed of two separate plates and are manufactured by milling metallic blocks. The gap between the two metallic plates eliminates the need for electrical contact between them. This feature allows the resonators to be stacked in different layers. The filtering function is realized by producing a coupling between the stacked resonators. The measurement results of the manufactured filters are in good agreement with full-wave simulations, even without any tuning or adjustments.

On the Performance of Mixed RF/FSO Variable Gain Dual-Hop Transmission Systems with Pointing Errors (2013)

In this work, the performance analysis of a dual-hop relay transmission system composed of asymmetric radio-frequency (RF) and unified free-space optical (FSO) links subject to pointing errors is presented. These unified FSO links account for both types of detection techniques (i.e. indirect modulation/direct detection (IM/DD) as well as heterodyne detection). More specifically, we derive new exact closed-form expressions for the cumulative distribution function, probability density function, moment generating function, and moments of the end- to-end signal-to-noise ratio of these systems in terms of the Meijer's G function. We then capitalize on these results to offer new exact closed-form expressions for the outage probability, higher-order amount of fading, average error rate for binary and M-ary modulation schemes, and ergodic capacity, all in terms of Meijer's G functions. All our new analytical results are verified via computer-based Monte-Carlo simulations.
Linear Furano Compounds: Synthesis of 7<i>H</i>-Furo[3,2-g][1]benzopyran-7-ones (1986)

Abstract A novel synthesis of 2-aroyl-7H-furo[3,2-g][1]benzopyran-7-ones, viz., IIIa and b was reported by condensing 2-benzoyl- and 2-(p-methoxybenzoyl)-3-methyl-5-acetyl-6-hydroxybenzofuran (Ia and b) with C6H5CH2COONa-Ac2O. VI was synthesised by condensing 7-hydroxy-6-benzoyl-4,8-dimethylcoumarin (IV) with V. The basic ethers (IIId–j) were synthesised by demethylating IIIb with pyridinehydrochloride and resultant IIIc was condensed with N,N-dialkyl-2-haloalkanamine hydrochlorides. UV, IR, 1H NMR, and Mass spectral data are also given.
