Atypical Brain Mechanisms of Prediction According to Uncertainty in Autism (2016)

Resistance to change is often reported in autism and may arise from an inability to predict events in uncertain contexts. Using EEG recorded in 12 adults with autism and age-matched controls performing a visual target detection task, we characterized the influence of a certain context (targets preceded by a predictive sequence of three distinct stimuli) or an uncertain context (random targets) on behavior and electrophysiological markers of predictive processing. During an uncertain context, adults with autism were faster than controls to detect targets. They also had an enhancement in CNV amplitude preceding all random stimuli-indexing enhanced preparatory mechanisms, and an earlier N2 to targets-reflecting faster information processing-compared to controls. During a certain context, both controls and adults with autism presented an increase in P3 amplitude to predictive stimuli-indexing information encoding of the predictive sequence, an enhancement in CNV amplitude preceding predictable targets-corresponding to the deployment of preparatory mechanisms, and an earlier P3 to predictable targets-reflecting efficient prediction building and implementation. These results suggest an efficient extraction of predictive information to generate predictions in both controls and adults with autism during a certain context. However, adults with autism displayed a failure to decrease mu power during motor preparation accompanied by a reduced benefit in reaction times to predictable targets. The data reveal that patients with autism over-anticipate stimuli occurring in an uncertain context, in accord with their sense of being overwhelmed by incoming information. These results suggest that adults with autism cannot flexibly modulate cortical activity according to changing levels of uncertainty.

Comparison of Two Ultrasonic Instruments for Post Removal (2002)

The relative performance of two different ultrasonic units commonly used clinically for post removal was evaluated using tips designed specifically for post vibration. Twenty-four extracted maxillary and mandibular cuspids with crowns removed at the labial cementoenamel junction were treated endodontically. Post spaces were made 10 mm into the roots before cementing a 16 mm #5 (0.050-inch) Para-Post with zinc phosphate cement. The teeth were divided into three similar groups of eight. Post retention was assessed in group 1. Ultrasonic vibration was applied to groups 2 and 3 until post removal. The average force required to dislodge the posts from the teeth in group 1 (control group, no ultrasound) was 40.5 kg (SD = 12.3 kg). The average time for post removal in group 2 (Spartan) was 4:52 min (SD = 2:26). The average time for post removal in group 3 (Enac) was 1:31 min (SD = 0:34). The difference between groups 2 and 3 was statistically significant (p < 0.005). Use of ultrasonic tips designed for post vibration and maximization of audible sound level during ultrasonic treatment of posts seem to play an important role in the effectiveness and efficiency of post removal. The results obtained indicate that both the Enac ultrasonic unit with the ST-09 vibration tip and the Spartan ultrasonic unit with the Analytic VT-S tip were effective. Nevertheless, the Enac ultrasonic unit with the ST-09 vibration tip was clearly more efficient under these study conditions, resulting in typical post removal times of <2 min.
An optimization method for the decision threshold level in optical receivers for WDM-PONs (2006)

We demonstrate an optimization method of the decision threshold level in optical receivers for WDM-PONs based on wavelength locked Fabry-Perot laser diodes. The decision threshold level is controlled by the average optical power. For the WDM-PON with 100 GHz channel spacing, we reduced required injection power for color-free operation by 6 dB using the proposed method.

A study on the variable radiation pattern antenna using a parasitic slot (2004)

It is advantageous for cellular phones or WLAN-APs (wireless LAN access points) that their antennas have variable radiation patterns in certain cases, such when they are mounted on a wall or for the purpose of avoiding interference. Most conventional antennas, such as reactively controlled directive arrays, are composed of multiple elements of identical shape to resolve the above-mentioned issues. This work proposes a novel variable radiation pattern antenna consisting of an inverted-F antenna and a parasitic slot with an electrical switch, and shows its fundamental characteristics and the appropriateness of its parameter optimization with GA.
Effect of OROS® controlled‐release delivery on the pharmacokinetics and pharmacodynamics of oxybutynin chloride (2001)

Oxy-XL maintains relatively constant plasma drug and metabolite concentrations and minimizes first-pass metabolism of oxybutynin. The metabolite appears to contribute to dry mouth associated with oxybutynin, and following Oxy-XL metabolite exposure is reduced compared with IR-Oxy. Consequently less dry mouth was observed with Oxy-XL as compared with IR-Oxy.

Photocatalytic properties of layered perovskite tantalates, MLnTa2O7 (M = Cs, Rb, Na, and H; Ln = La, Pr, Nd, and Sm) (2003)

Layered lanthanide tantalates and their ion-exchanged phases (MLnTa2O7, M = Cs, Rb, Na, and H; Ln = La, Pr, Nd, and Sm) were prepared to evaluate their photocatalytic activity for water splitting under UV irradiation. The optical band gap energy was dependent on the lanthanide, Ln, but negligibly affected by the monovalent interlayer cations, M. By contrast, the photocatalytic activity was strongly affected by not only Ln but also M; the highest activity was attained by a series of M = Rb with a sequence of Ln: Nd > Sm > La > Pr. The effect of Ln can be explained by the energy level and hybridization of the Ln 4f band, which was discussed based on the results of electronic structure calculations in our previous work. The ion exchanged phases (M = Na and H) having deformed hydrous layer structure were less active compared to anhydrous Rb and Cs phases, whereas the NiOx loading of the Na phase greatly enhances the activity. It seems that the high mobility of water molecules between the layers allows the interlayer sites to behave as active sites for the photocatalytic reaction over NiOx-loaded catalysts.

A comparative study of multimodal vs. bimodal polyethylene pipe resins for PE‐100 applications (2005)

Abstract In this paper several high density polyethylene pipe resins are compared to polyethylene resins made in the Phillips Loop‐Slurry Process (single‐reactor), using a catalyst of chromium on modified aluminophosphate (Cr/AlPO 4 ). A brief description of the Cr/AlPO 4 system is presented along with polymer chain architecture (i.e., topology) and other structural aspects of polymers made from these catalysts. The physical properties of these resins and their fabricated pipe processing/performance properties were compared to both PE80 and conventional bimodal type PE‐100 resins. Results from this study show that high‐density polyethylene resins made from Cr/AlPO 4 catalysts possess primary structural attributes that are truly unique for chromium‐catalyzed resins. These multimodal resins have very high molecular weights (MW; M w &gt; 400 kg/mol) and exceptionally broad MW distributions (MWD; M w / M n &gt; 50). Topologically, these resins were found to have uniform short chain branching distributions across the MWD; as in polymers made from single site metallocene catalysts) and significantly reduced levels (10 times less) of long chain branching when compared to resins made using chromium catalysts on conventional supports. Furthermore, results from rheological, fabricated pipe processing, and performance studies suggest that these resins should be especially well suited for high performance pipe applications. Pipe samples made from these resins were found to meet PE‐100 requirements including low temperature impact properties. POLYM. ENG. SCI., 45:1203–1213, 2005. © 2005 Society of Plastics Engineers
Development of a New Serological Test for SerotypingHaemophilus parasuisIsolates and Determination of Their Prevalence in North America (2004)

Haemophilus parasuis causes polyserositis in swine. Fifteen serovars have been characterized by immunodiffusion test, but many field strains are not typeable. Isolates (n = 300) of H. parasuis from animals in North America were serotyped by a new indirect hemagglutination test. The test was rapid and effective for serotyping of H. parasuis, and serovars 4, 5, 13, and 7 were the most prevalent serotypes.
Quickest seizure onset detection in drug-resistant epilepsy (2012)

Epilepsy affects 50 million people worldwide, and 30% remain drug-resistant. This has increased interest in responsive neurostimulation, which is assumed to be most effective when administered right at the seizure onset. We propose a novel framework for seizure onset detection that involves (i) constructing statistics from intracranial multichannel EEG signals (iEEG) to distinguish non-ictal vs. ictal states; (ii) modeling the dynamics of these statistics in each state and the state transitions; (iii) developing an optimal control-based “quickest detection” (QD) strategy to estimate the transition time from non-ictal to ictal states from sequential iEEG measurements. The QD strategy minimizes a cost function of detection delay and false positive probability. The solution is a threshold that non-monotonically decreases over time and avoids responding to rare events that normally trigger false positives. We applied QD to a preliminary dataset of two drug-resistant epileptic patients (87h continuous recordings, 34 and 28 electrodes, respectively, 5 seizures), and achieved 100% sensitivity with low false positive rates (0.16 false positive/h).

Risk Factors for Retinopathy in Type 1 Diabetes: The DCCT/EDIC Study (2019)

Thermodynamics of Metal Ion Binding. 1. Metal Ion Binding by Wild-Type Carbonic Anhydrase (2001)

Understanding the energetic consequences of molecular structure in aqueous solution is a prerequisite to the rational design of synthetic motifs with predictable properties. Such properties include ligand binding and the collapse of polymer chains into discrete three-dimensional structures. Despite advances in macromolecular structure determination, correlations of structure with high-resolution thermodynamic data remain limited. Here we compare thermodynamic parameters for the binding of Zn(II), Cu(II), and Co(II) to human carbonic anhydrase II. These calorimetrically determined values are interpreted in terms of high-resolution X-ray crystallographic data. While both zinc and cobalt are bound with a 1:1 stoichiometry, CAII binds two copper ions. Considering only the high-affinity site, there is a diminution in the enthalpy of binding through the series Co(II) --> Zn(II) --> Cu(II) that mirrors the enthalpy of hydration; this observation reinforces the notion that the thermodynamics of solute association with water is at least as important as the thermodynamics of solute-solute interaction and that these effects must be considered when interpreting association in aqueous solution. Additionally, DeltaC(p) data suggest that zinc binding to CAII proceeds with a greater contribution from desolvation than does binding of either copper or cobalt, suggesting Nature optimizes binding by optimizing desolvation.
SWAMP: Smart Water Management Platform Overview and Security Challenges (2018)

The intensive use of technology in precision irrigation for agriculture is getting momentum in order to optimize the use of water, reduce the energy consumption and improve the quality of crops. Internet of Things (IoT) and other technologies are the natural choices for smart water management applications, and the SWAMP project is expected to prove the appropriateness of IoT in real settings with the deployment of on-site pilots. At the same time, the more intense the use of technology is, agriculture turns new security risks, which may affect both crop development and the commodities market. A security breach may irreversibly compromise a crop and data eavesdropping may compromise price and contracts exposing sensitive data such crop quality, development or management. This paper discusses security challenges and technologies for the application of IoT in agriculture and indicates that one of the most relevant challenges to be handled in SWAMP project is dealing with the multitude of behaviors from IoT application and what would be considered as normal and what would be considered as a threat.

Investigation of InGaAs-InP quantum wells by optical spectroscopy (1986)

A detailed study of the optical properties of InGaAs-InP single quantum wells (QWS) grown by atmospheric-pressure metal-organic chemical vapour deposition is described. Photoluminescence (PL), photoluminescence excitation (PLE), photoconductivity (PC) and electroreflectance (ER) are employed to study both undoped and modulation-doped quantum wells. The role of extrinsic processes in determining the low-temperature PL spectra is demonstrated from the variation of peak position and linewidth with temperature. The best PL linewidth obtained for a 150 AA well is 5.3 meV, fairly close to the limit imposed by alloy fluctuations in the InGaAs. The role of free carriers in the undoped QWS in determining the energy threshold for optical absorption is demonstrated from a comparison of PLE and PC spectra. Lineshape fitting of the PL spectra is described, and it is deduced that at 160K recombination processes in both doped and undoped QWS proceed with wavevector conservation, although at lower temperatures highly anomalous lineshapes are found in modulation-doped samples. The observation of a threshold in PC spectra under forward bias is interpreted as a transition from the valence-band well to the top of the conduction well. The ratio of the conduction- to valence-band discontinuities is deduced to be approximately 0.4:0.6.
Biodiesel Fuel from Vegetable Oil Wastes by Supercritical Methanol. (2000)

The transesterification reaction of rapeseed oil in supercritical methanol was investigated in this study, without using any catalyst. It was consequently demonstrated that, in a preheating temperature of 350°C, 240 sec of supercritical treatment of methanol was sufficient to convert rapeseed oil to methyl esters with the molar ratio of methanol in triglycerides being 42. In addition, although prepared methyl esters were basically the same as those of the common method with a basic catalyst, the yield of methyl esters by the former was found to be higher than that by the latter due to a successful methyl esterification of free fatty acids present in the rapeseed oil. Furthermore, the kinetics study showed that the conversion rate of rapeseed oil to its methyl esters was found to increase dramatically in the supercritical state. Therefore, supercritical methanol process which requires the shorter reaction time and simpler purification procedure because of the catalyst unused, would become a powerful method for recycling vegetable oil wastes to biodiesel fuel.

Crystallization behavior of elastomeric block copolymers: Thermoplastic polyurethane and polyether‐block‐amide (2008)

Abstract The isothermal crystallization kinetics of melt‐blown webs produced from a series of elastomeric block copolymers was studied through differential scanning calorimetry (DSC). Three hardness grades were selected for a polyester and a polyether Elastollan® thermoplastic polyurethane and Pebax® polyether‐ block ‐amide copolymers. The Avrami crystallization kinetics parameters, k and n , were derived from two different methods: (1) traditional Avrami model and (2) derivative of the Avrami model proposed by Kurajica et al. (Croat Chem Acta 2002, 75, 693). The kinetic parameters from both models were consistent and showed good correlation. For all polymer types and hardness grades, crystallization kinetics were interpreted with the derivative model (Kurijica et al.) since it could be directly fitted to untransformed DSC isothermal crystallization data, and thus reduces the errors involved in Avrami analysis. The values of the Avrami exponent, n ranged between 2.59 and 3.41, indicating similar nucleation and growth mechanisms. These n values and morphological observations indicate that crystallization occurs in these copolymers in three dimensions from pre‐existing nuclei and the crystals grow under isothermal conditions. This suggests that, in these elastomeric copolymers, crystallization of the hard segments drives microphase separation into crystalline and amorphous regions rather than formation of hard and soft domains. © 2008 Wiley Periodicals, Inc.

Statistical performance analysis of the minimum-norm method (1989)

The performance of the minimum-norm method, both root and spectral forms, for estimating the direction of arrival (DOA) of plane waves in white noise is analysed for the case of a linear equispaced sensor array. In particular, asymptotic results for the mean squared error in the estimates of the direction of arrival are derived. Simple closed-form expressions are derived for the one and two source case to get further insight. Computer simulations are provided to substantiate the analysis. The results obtained are compared to those obtained for root-MUSIC and it is shown that the relative performance of the two methods is directly dependent on the ratio of their parameter sensitivities.
Simultaneous shape and topology optimization of wings (2022)

This paper presents a method for simultaneous optimization of the outer shape and internal topology of aircraft wings, with the objective of minimizing drag subject to lift and compliance constraints for multiple load cases. The physics are evaluated by the means of a source-doublet panel method for the aerodynamic response and linear elastic finite elements for the structural response, which are one-way coupled. At each design iteration, a mapping procedure is applied to map the current wing shape and corresponding pressure loads to the unfitted finite element mesh covering the design domain. Wings of small fixed-wing airplanes both with and without a stiffening strut are optimized. The resulting wings show internal topologies with struts and wall-truss combinations, depending on the design freedom of the shape optimization. The lift distributions of the optimized wings show patterns like the ones obtained when performing optimization of wing shapes with constraints on the bending moment at the root.

Ni-FUSI on high-k as a candidate for 65nm LSTP CMOS (2005)

We show for the first time that full Ni silicidation (Ni-FUSI) of poly gates in combination with Hf based gate dielectrics meets the required device performance for the 65nm LSTP technology node. Important device parameters, like C/sub inv/, mobility and drive currents exhibit significant improvement without compromising the oxide integrity and reliability. The drive of nMOS and pMOS transistors for the V/sub DD/=1.1V at 10pA//spl mu/m off state leakage is 575/spl mu/A/ /spl mu/m and 1650 /spl mu/A//spl mu/m respectively.
