Speech processes in the cognitive learning of young children (1973)

Because “talking one's way” is a dynamic aid to learning, the relationship of thought, speech, and language to the development of cognitive formations is explored and discussed in this essay.
A Bayesian Approach to Multipath Mitigation in GNSS Receivers (2009)

Multipath is known to be one of the most dominant sources of accuracy degradation in satellite-based navigation systems. Multipath may cause biased position estimates that could jeopardize high-precision applications. This paper considers the problem of tracking the time-variant synchronization parameters of both the line-of-sight signal (LOSS) and its multipath replicas. In particular, the proposed algorithm tracks time-delays, amplitudes, phases and proposes a procedure to extract Doppler shifts from complex amplitudes. However, the interest is focused on LOSS time-delay estimates, since those provide the means to compute user's position. The undertaken Bayesian approach is implemented by a particle filter. The selection of the importance density function, from which particles are generated, is performed using a Gaussian approximation of the posterior function. This selection provides a particle generating function close to the optimal, which yields to an efficient usage of particles. The complex-linear part of the model, i.e., complex amplitudes, is tackled by a Rao-Blackwellization procedure that implements a complex Kalman filter for each generated particle, thus reducing the computational load. Computer simulation results are compared to other Bayesian filtering alternatives (namely, the extended Kalman filter, the unscented Kalman filter and the sequential importance resampling algorithms) and the posterior Cramer-Rao bound.
Differential antifungal effects of stereoisomeric styrylimidazole compounds on Candida albicans and Trichophyton rubrum. (1990)

New active antifungal agents with 1-(2-phenyl-1-alkenyl)-1H-imidazole structure were prepared and their structure-activity relationships were examined.The most potential activity among these derivatives was observed in Z-2-(2, 4-dichlorophenyl)-3-methyl-1-pentenyl-1H-imidazole (coded as GBR-14206), which displayed a marked activity against not only Candida but Trichophyton. It was of particular interest to note that the antifungal profiles of these styrylimidazole derivatives were dependent on the geometry in the styryl portion; the Z-isomers were found to be more potent against Candida than the corresponding E-isomers, whereas the E-isomers were more effective for Trichophyton.Thus, the geometry in the styryl portion of 1-(2-phenyl-1-alkenyl)-1H-imidazole derivatives is crucial for their differential antifungal potency.
A paradigm shift in GP-GPU computing (2014)

General purpose computing on GPUs have became increasingly popular over the last decade. Scientific applications with SIMD computation characteristics show considerable performance improvements when run on these massively parallel architectures. However, data dependencies across thread blocks significantly impact the degree of achievable parallelism by requiring global synchronization across multi-processors (SMs) inside the GPU.
RADICAL PRINCIPLES AND THE LEGAL INSTITUTION OF MARRIAGE: DOMESTIC RELATIONS LAW AND SOCIAL DEMOCRACY IN SWEDEN (1990)

Reforms in Sweden in the last twenty years have produced a distinctive system of domestic relations law. The first objective of this article is to analyse the initial stage in this programme of reforms: the revision of marital capacity and divorce laws in 1973. The immediate practical importance of changes in these two areas will be limited: the introduction of the Swedish Marriage Code of 1920 may well have had a more tangible impact on society. However, the legislation enacted in 1973, which has now been consolidated in a new Marriage Code, altered the foundations of the legal institution of marriage in Sweden. These reforms represent one of many attempts at the development of new principles of social organization in this jurisdiction. The second objective of this article is to identify influences on the development of Swedish domestic relations law. The purpose is not to provide a detailed analysis of the response to commission proposals as they have passed through the ‘remiss’ or consultation stage, and on to Government Bills and legislation. Any broader enquiry than this is inevitably somewhat speculative and risks, for an outsider, superficial and ethnocentric assessments. However, with all these caveats, the argument in this article is that the first stage of the general programme of reforms can be identified with political programmes of the Social Democratic Party, and that beyond this, reforms in Sweden in this area of law appear as the logical product of an ideology developed by a particular form of social democracy. The focus here is on the structure and evolution of Swedish marriage laws: in conclusion an assessment is made of their political significance.

Activation of endothelial cell phospholipase D by hydrogen peroxide and fatty acid hydroperoxide. (1993)

We have investigated oxidant-mediated stimulation of phospholipase D (PLD) activity in bovine pulmonary artery endothelial cells (BPAEC), prelabeled with [32P]orthophosphate or [32P]lysophospholipids. Treatment of cells incubated in Hanks' balanced salt solution (HBSS) containing 0.5% ethanol with hydrogen peroxide (H2O2) or linoleic acid hydroperoxide (18:2-OOH) enhanced the formation of 32P-labeled phosphatidylethanol (PEt) and phosphatidic acid (PA) in a dose- and time-dependent manner, indicating the activation of PLD. The H2O2- and 18:2-OOH-mediated PLD activation was not associated with cytotoxicity as determined by [3H]deoxyglucose release. The addition of ferrous chloride (50 microM) augmented H2O2-induced formation of [32P]PEt and [32P]PA about 2-fold, whereas the addition of the iron chelator desferoxamine blocked the potentiating effect of ferrous chloride. Replacement of the HBSS medium with Medium 199 containing 20% calf serum also potentiated the effect of H2O2-induced PLD activation. In addition to phosphatidylcholine (PC), phosphatidylethanolamine (PE), and phosphatidylinositol (PI) were readily hydrolyzed by PLD in response to H2O2 and 18:2-OOH treatment. The substrate specificity for oxidant-stimulated PLD activity differed from that observed in the presence of bradykinin or exhibited by agonist stimulation with 12-O-tetradecanoylphorbol 13-acetate (TPA) where PC was the major phospholipid hydrolyzed by PLD. The formation of PEt in the presence of H2O2 and 18:2-OOH was not abolished by chelation of either extracellular Ca2+ with EGTA (5 mM) or intracellular Ca2+ with 1,2-bis-(2-aminophenoxy)ethane-N,N,N,N-tetraacetic acid-acetoxymethyl ester (BAPTA-AM) (25 microM, 30 min). Furthermore, pretreatment of BPAEC with the protein kinase C (PKC) inhibitor staurosporine and down-regulation of PKC by chronic TPA treatment (100 nM, 18 hr) had no effect on H2O2-induced PLD activation, suggesting that PLD activation by H2O2 is independent of PKC activity. It is possible that H2O2- and 18:2-OOH-induced activation of PLD represents an important mechanism to produce PA and diacylglycerol in endothelial cells.
Direct Alteration of the P/Q-Type Ca<sup>2+</sup>Channel Property by Polyglutamine Expansion in Spinocerebellar Ataxia 6 (1999)

Spinocerebellar ataxia 6 (SCA6) is caused by expansion of a polyglutamine stretch, encoded by a CAG trinucleotide repeat, in the human P/Q-type Ca(2+) channel alpha(1A) subunit. Although SCA6 shares common features with other neurodegenerative glutamine repeat disorders, the polyglutamine repeats in SCA6 are exceptionally small, ranging from 21 to 33. Because this size is too small to form insoluble aggregates that have been blamed for the cause of neurodegeneration, SCA6 is the disorder suitable for exploring the pathogenic mechanisms other than aggregate formation, whose universal role has been questioned. To characterize the pathogenic process of SCA6, we studied the effects of polyglutamine expansion on channel properties by analyzing currents flowing through the P/Q-type Ca(2+) channels with an expanded stretch of 24, 30, or 40 polyglutamines, recombinantly expressed in baby hamster kidney cells. Whereas the Ca(2+) channels with </=24 polyglutamines showed normal properties, the Ca(2+) channels with 30 or 40 polyglutamines exhibited an 8 mV hyperpolarizing shift in the voltage dependence of inactivation, which considerably reduces the available channel population at a resting membrane potential. The results suggest that polyglutamine expansion in SCA6 leads to neuronal death and cerebellar atrophy through reduction in Ca(2+) influx into Purkinje cells and other neurons. Besides the widely accepted notion that polyglutamine stretches exert toxic effects by forming aggregates, expanded polyglutamines directly alter functions of the affected gene product.

Cloud-Vision: Real-time face recognition using a mobile-cloudlet-cloud acceleration architecture (2012)

Face recognition applications for airport security and surveillance can benefit from the collaborative coupling of mobile and cloud computing as they become widely available today. This paper discusses our work with the design and implementation of face recognition applications using our mobile-cloudlet-cloud architecture named MOCHA and its initial performance results. The challenge lies with how to perform task partitioning from mobile devices to cloud and distribute compute load among cloud servers (cloudlet) to minimize the response time given diverse communication latencies and server compute powers. Our preliminary simulation results show that optimal task partitioning algorithms significantly affect response time with heterogeneous latencies and compute powers. Motivated by these results, we design, implement, and validate the basic functionalities of MOCHA as a proof-of-concept, and develop algorithms that minimize the overall response time for face recognition. Our experimental results demonstrate that high-powered cloudlets are technically feasible and indeed help reduce overall processing time when face recognition applications run on mobile devices using the cloud as the backend servers.
Prediction of paroxysmal atrial fibrillation onset by using ECG (2012)

The advances in medical technologies increased the importance of a reliable arrhythmia predictor to predict the arrhythmia onset. The goal of this study is to predict paroxysmal atrial fibrillation (PAF) onset by using electrocardiograph (ECG) signals. 53 pairs of 30 minute ECG signals were used for this purpose. Complex correlation measures (CCM) were calculated for 5 minute ECG windows. It was observed that the standard deviation of CCM values obtained for records just before the PAF onset were significantly greater than the ones obtained away from PAF onset. Based on this observation, the records just before to PAF onset were correctly predicted with 72% success rate.

77 GHz MMIC T/R module for diplex radar application in collision avoidance radar (CAR) (2002)

A MMIC chip set has been developed for use in a forward-looking Collision Avoidance Radar (CAR) at 77 GHz with diplex radar configuration. The chip set is designed with available MMIC foundry processes using a mix of 0.18 and 0.10 /spl mu/m T-gate PHEMT technology. The diplex radar has certain advantages over FMCW and FSK methods commonly adopted in CAR applications. For example, since this method allows for less stringent phase noise requirements on the oscillator, a common MMIC process can be used for all of the MMIC designs. The complete MMIC module has been evaluated for receive and transmit characteristics at 77 GHz and is presently awaiting road testing.

An evaluation of void‐filling interpolation methods for SRTM data (2007)

The Digital Surface Model that has been derived from the February 2000 Shuttle Radar Topography Mission (SRTM) has been one of the most important publicly available new spatial datasets in recent years. However, the ‘finished’ version of the data still contains data voids (some 836,000 km2) – and other anomalies - that prevents immediate use for a wide range of applications. These voids can be filled using a range of interpolation algorithms in conjunction with other sources of elevation data, but there is little guidance on the most appropriate void filling method. This paper describes; (i) a methodology to fill voids using a variety of methods, (ii) a methodology to determine the most appropriate void filling algorithms using a classification of the voids based on their size and a typology of their surrounding terrain; and (iii) the classification of the most appropriate algorithm to each of the 3,339,913 voids in the SRTM data. Based on a sample of 1,304 artificial but realistic voids across six terrain types and eight void size classes, we found that the choice of void filling algorithm is dependent on both the size and terrain type of the void. Contrary to some previous findings, the best methods can be generalised as: Kriging or Inverse Distance Weighting interpolation for small and medium size voids in relatively flat low-lying areas; Spline interpolation for small and medium sized voids in high altitude and dissected terrain; Triangular Irregular Network or Inverse Distance Weighting interpolation for large voids in very flat areas, and an advanced Spline Method (ANUDEM) for large voids in other terrains.
Estimating the number of release sites and probability of firing within the nerve terminal by statistical analysis of synaptic charge (2002)

Investigating the function of individual synapses is essential to understanding the mechanisms that influence the efficacy of chemical synaptic transmission. The known simplicity of the synaptic structure at the crayfish neuromuscular junction (NMJ) and its quantal nature of release allows an assessment of discrete synapses within the motor nerve terminals. Our goal in this article is to investigate the effect of the stimulation frequency on the number of active release sites (n) and the probability of release (p) at those active sites. Because methods based on direct counts often provide unstable joint estimates of (n) and (p), we base our analysis on mixture modeling. In particular, the mixture modeling approach is used to estimate (n) and (p) for stimulation frequencies of 1 Hz, 2 Hz, and 3 Hz. Our results indicate that as the stimulation frequency increases, new sites are recruited (thus increasing n) and the probability of release (p) increases.
Nasal challenge studies with bradykinin: influence upon mediator generation (1991)

Previous studies have shown that nasal allergen provocation leads to dose-dependent increases of inflammatory mediators, e.g. histamine, kinins, LTC4 and PGD2 in nasal lavages. To investigate further the interaction of these mediators, a titration study with intranasal bradykinin (Bk) application (maximal dose 100 nmol/nostril) and consecutive lavage were performed in eight grass-pollen-allergic patients out of season, and five controls. The nasal lavages were analysed for albumin, N-alpha-tosyl-L-arginine methyl ester (TAME) esterase activity, histamine, 9 alpha,11 beta-PGF2, and LTC4. The clinical reactions were measured with a subjective symptom score. A dose-dependent elevation of albumin was found which was significantly higher in patients with allergic and non-allergic rhinitis compared with normal volunteers. TAME-esterase activity also increased in relation to the dosage of Bk given without significant difference between the various groups. No influence on histamine, LTC4 and 9 alpha,11 beta-PGF2, release (PGD2 metabolite) was seen. Short-lasting clinical symptoms like irritation, sneezing, and obstruction were noticed after the two highest Bk dosages (10 and 100 nmol). We conclude that intranasally applied Bk induces a dose-dependent plasma leakage into the nasal cavity, which is significantly higher in patients with seasonal allergic rhinitis out of season compared to normals. Bk does not seem to affect the mast cell since histamine, LTC4 and 9 alpha,11 beta-PGF2 levels do not alter. The ability to induce relevant symptoms of rhinitis provides strong support for the hypothesis that kinins may be important mediators of inflammatory disorders of the upper airways.
Nonlinear Optical Properties of Polydiacetylenes (1983)

The nonlinear optical properties of novel, soluble polydiacetylenes are reviewed and discussed. The nonlinear optical properties are determined using resonance Raman scattering, coherent anti-stokes Raman scattering and coherent stokes Raman scattering. The two-photon polarizability is found to be very large in these materials. General aspects of the third-order susceptibility of these materials are also discussed.
