Strategies and Metastrategies in Learning and Performing Self-Paced Athletic Skills (1988)

This article explores techniques that individuals can use during learning and performance to influence thoughts, feelings, and subsequent achievement. Of concern is knowing how to learn—how to perform. Learning strategies can be isolated and task-specific, or combinatorial and more generally applied to related tasks. Researchers have primarily labored in the first area, frequently demonstrating the effectiveness of a particular learning strategy in improving the learning of a certain activity. In more recent years the second area, typically defined as metastrategies, is attracting the interest of scholars. Since the notion of metastrategies is vague, they are difficult to define and pose a challenge to investigate as to their influence in learning/performing situations. This article begins with a general discussion about information processing processes involved in attaining movement skill, and the use of strategies and metastrategies. A proposed global strategy, the Five-Step Strategy, is presented that should be useful in the learning/performing of all types of closed (self-paced) athletic acts. The strategies include readying, imaging, focusing, executing, and evaluating. The learning of task-pertinent strategies appears to be particularly influential in a number of ways, ultimately leading to a higher probability of learning efficiency and performance excellence.
Scalable One-Pot - Liquid-Phase Oligonucleotide Synthesis for Model Network Hydrogels (2020)

Solid-phase oligonucleotide synthesis (SPOS) based on phosphoramidite chemistry is currently the most widespread technique for DNA and RNA synthesis, but suffers from scalability limitations and high reagent consumption. Liquid-phase oligonucleotide synthesis (LPOS) uses soluble polymer supports and has the potential of being scalable. However, at present, LPOS requires 3 separate reaction steps and 4-5 precipitation steps per nucleotide addition. Moreover, long acid exposure times during the deprotection step degrade sequences with high A-content (adenine) due to depurination and chain cleavage. In this work, we present the first one-pot liquid-phase DNA synthesis technique, which allows the addition of one nucleotide in a one-pot reaction of sequential coupling, oxidation and deprotection, followed by a single precipitation step. Furthermore, we demonstrate how to suppress depurination during the addition of adenine nucleotides. We showcase the potential of this technique to prepare high-purity 4-arm PEG‑T20 (T = thymine) and 4-arm PEG-A20building blocks in multi-gram scale. Such complementary 4-arm PEG-DNA building blocks reversibly self-assemble into supramolecular model network hydrogels, and facilitate the elucidation of bond lifetimes. These model network hydrogels exhibit new levels of mechanical properties, high stability at room temperature (melting at 44 ‎°C), and thus open up pathways to next-generation, scalable DNA-materials programmable through sequence recognition and available for macroscale applications.

<div class="htmlview paragraph">A pilot plant facility has now been established to build DC electrolumescent panels. A new product is being made which combines analogue and digital readouts on one panel. Any panel up to 6″ × 18″ can be made due to the process simplicity which consists largely of screen printing techniques. The pilot product is 2″ × 7″ and displays are made six at a time. A combination of custom designed I.C.'s and microprocessor drive can be used to provide full, flexible solid state instrumentation.</div>
Anti-jamming timing channels for wireless networks (2008)

Wireless communication is susceptible to radio interference, which prevents the reception of communications. Although evasion strategies have been proposed, such strategies are costly or ineffective against broadband jammers. In this paper, we explore an alternative to evasion strategies that involves the establishment of a timing channel that exists in spite of the presence of jamming. The timing channel is built using failed packet reception times. We first show that it is possible to detect failed packet events inspite of jamming. We then explore single sender and multisender timing channel constructions that may be used to build a low-rate overlay link-layer. We discuss implementation issues that we have overcome in constructing such jamming-resistant timing channel, and present the results of validation efforts using the MICA2 platform. Finally, we examine additional error correction and authentication mechanisms that may be used to cope with adversaries that both jam and seek to corrupt our timing channel.
Self-Assembled Layer of Thiolated Protein G as an Immunosensor Scaffold (2006)

In this study, our goal was to produce a self-assembled layer on a gold electrode that would enable the capture of antibodies orientated for maximum binding to their specific antigen in an immunosensor. To achieve this, the amine groups from lysine residues in protein G were initially converted to thiol groups with 2-iminothiolane. The high affinity of thiols for a gold surface facilitates the direct formation of a self-assembled protein G layer. Following this, the coated gold electrode was exposed to a solution of capture antibody (mAb1) so that these antibodies could attach to the protein G layer through their nonantigenic regions, leaving antigen binding sites available with minimal steric hindrance for binding of target analyte. A comparative study between this method and the more conventional strategy of covalently attaching a layer of nonthiolated protein G on an alkanethiol self-assembled monolayer-coated gold electrode has been performed. Based on a reduced preparation time, and an enhanced capacity for immobilized capture antibody to bind its target analyte due to a more favorable orientation, the layer of thiolated protein G was found to be a more suitable backbone for an electrochemical immunosensor.
Dielectric layers suitable for high voltage integrated trench capacitors (2011)

In this work, two different dielectric stacks consisting of silicon dioxide (SiO2) and silicon nitride (Si3N4) are analyzed regarding their suitability as dielectrics in a high voltage trench capacitor. The processing of the dielectric layers and the resulting edge-coverage in the trench holes are described. Voltage and temperature dependence of the trench capacitance are analyzed and compared with planar capacitors for reference. The leakage currents are measured and the current transport mechanisms are analyzed. The outstanding properties of the devices are a high capacitance per area (1.25 nF/mm2 for SiO2 and 1.5 nF/mm2 for Si3N4), a low temperature coefficient (SiO2: 18 ppm/K; Si3N4: 85 ppm/K from 25–100 °C), and a low leakage current (&lt;1×10−6 A) for voltages up to 400 V for Si3N4.
Iliac arteriovenous fistula due to spinal disk surgery. Causes severe hemodynamic repercussion with pulmonary hypertension. (1993)

We present a case of a 46-year-old man with a pulsatile mass in the left inferior abdominal quadrant that irradiated a continuous murmur extending to the left lumbar region. Despite an 8-year history of cardiomegaly, he appeared to be asymptomatic except for the mass and could recollect no traumatic injury or surgery that might have caused it. Near the vertebral column, we found a small scar, the result of spinal disk surgery 11 years before. Following chest radiography and electrocardiography, we located the suspected arteriovenous fistula by selective angiography of the aorta and its branches: a communication of the left iliac artery with the left iliac vein had resulted in a very large left-to-right shunt and a severely dilated inferior vena cava. We then divided and isolated the arterial segment containing the fistula, but left this segment in continuity with the left iliac vein by over-sewing both ends. To avoid injury to surrounding structures, dissection was limited to the area of maximal thrill. Hemodynamic improvement was immediate, and the postoperative course was uneventful. At the present time, almost 3 years postoperatively, the patient is asymptomatic.
Local Climate Zones for Urban Temperature Studies (2012)

The effect of urban development on local thermal climate is widely documented in scientific literature. Observations of urban–rural air temperature differences—or urban heat islands (UHIs)—have been reported for cities and regions worldwide, often with local field sites that are extremely diverse in their physical and climatological characteristics. These sites are usually described only as “urban” or “rural,” leaving much uncertainty about the actual exposure and land cover of the sites. To address the inadequacies of urban–rural description, the “local climate zone” (LCZ) classification system has been developed. The LCZ system comprises 17 zone types at the local scale (102 to 104 m). Each type is unique in its combination of surface structure, cover, and human activity. Classification of sites into appropriate LCZs requires basic metadata and surface characterization. The zone definitions provide a standard framework for reporting and comparing field sites and their temperature observations. The LCZ system is designed primarily for urban heat island researchers, but it has derivative uses for city planners, landscape ecologists, and global climate change investigators.
Abnormally high circulation levels of tissue plasminogen activator and plasminogen activator inhibitor-1 in patients with a history of ischemic stroke. (1994)

We evaluated 106 subjects with and 109 subjects without a history of ischemic stroke. All were attending a metabolic ward. The two groups were compared for major risk factors for ischemic events. A positive family history for ischemic complications of atherosclerosis was more common in subjects with a history of stroke than in those without; moreover, plasma levels of plasminogen activator inhibitor-1 (PAI-1) and tissue-type plasminogen activator (TPA) were higher in patients with documented previous events. A strong positive significant correlation was found between TPA and PAI-1 levels, and an interaction between age and TPA was observed when the sample was stratified according to ages being above or below 70 years. When the patient population was analyzed according to the number of ischemic events, it was found that 62 of the 106 subjects with a history of stroke had experienced more than one ischemic event. Under these conditions, the levels of TPA and PAI-1 still correlated with the occurrence of previous ischemic episodes. As in the whole patient sample, TPA was the strongest discriminator. We conclude that in subjects attending a metabolic ward, TPA and PAI-1 levels consistently help identify subjects with a history of cerebral ischemic episodes and that TPA is the strongest discriminator.
Perception of the Queen by Workers in the Honeybee Colony (1973)

SummaryWorkers gathered on cages containing a mated laying queen placed above a normal queenright colony. Fewer workers gathered on a cage when they could not touch the caged queen, or when she was dead, or when her mandibular glands had been removed. The number of workers on the cage was correlated with the amount of 9-oxodecenoic acid in the queen's head. Workers gathered on cages containing only 9-oxodecenoic acid on filter-paper that the bees could not touch. “Court” formation round a free queen was not diminished by removing her mandibular glands. The head of queens whose mandibular glands had been removed contained traces of 9-oxodecenoic acid. No hitherto unknown substance affecting worker bees' behaviour was detected in the queen's head. No sounds likely to be specifically communicative were heard from the queen or from workers that formed a “court” round her. Workers did not move from afar to form a “court” round a queen. It is concluded that in an undisturbed colony with a mated laying queen there is no attraction of workers towards the queen except over very short distances.
Fast and automatic city-scale environment modeling for an accurate 6DOF vehicle localization (2013)

To provide high quality augmented reality service in a car navigation system, accurate 6DoF localization is required. To ensure such accuracy, most of current vision-based solutions rely on an off-line large scale modeling of the environment. Nevertheless, while existing solutions require expensive equipments and/or a prohibitive computation time, we propose in this paper a complete framework that automatically builds an accurate city scale database using only a standard camera, a GPS and Geographic Information System (GIS). As illustrated in the experiments, only few minutes are required to model large scale environments. The resulting databases can then be used during a localization algorithm for high quality Augmented Reality experiences.
Synergism of protein kinase A, protein kinase C, and myosin light-chain kinase in the secretory cascade of the pancreatic beta-cell. (2000)

Protein phosphorylation by myosin light-chain kinase (MLCK), protein kinase A, and protein kinase C (PKC) plays a positive role in insulin secretion from the pancreatic beta-cell. To investigate the underlying mechanisms, we examined intracellular distribution of the insulin granules and MLCK by immunofluorescence and immunoelectron microscopies and also investigated intracellular traffic of the granules in cultured beta-cells (MIN6) by video microscopy. Considerable parts of MLCK immunoreactivity were colocalized with the insulin granules. Subcellular fractionation of MIN6 cell extracts revealed that myosin light chain (MLC) may be distributed with the insulin-rich fractions, and immunofluorescence staining using specific antibodies against mono- and diphosphorylated MLCs depicted presence of phosphorylated MLCs in the cytoplasm, in part, with colocalization with the insulin granules. Activation of PKC by 12-O-tetradecanoyl-phorbol 13-acetate (TPA) caused a shift of both insulin granules and MLCK to the cell periphery, which was not reproduced by the adenylate cyclase activator, forskolin. In contrast, forskolin, but not TPA, increased the granule movement. Costimulation of the beta-cell by TPA and forskolin induced drastic translocation of insulin granules and MLCK to the cell periphery, resulting in enormous potentiation of insulin release. These findings suggest that these protein kinases increase insulin granules in the ready-releasable pool by acting on different steps in the secretory cascade.
Dual reflector antenna with narrow broadside beam for omnidirectional coverage (1993)

A new type of high gain omnidirectional antenna is presented, particularly suited for higher frequencies (e.g. milllimetre waves): it is obtained with an axially symmetric dual reflector system, fed with an unconventional feed with conical pattern. The feed radiated field, after reflection on the parabolic subreflector and on the conical main reflector, is uniformly scattered in the plane perpendicular to the axis of the system, with vertical polarisation and narrow vertical beamwidth.
Detection of Islet β-Cell Death in Vivo by Multiplex PCR Analysis of Differentially Methylated DNA (2013)

Noninvasive detection of early β-cell death in type 1 diabetes might identify individuals in whom therapeutic interventions would preserve β-cell mass and prevent hyperglycemia. Recent studies in mice have shown that β-cell death produces a corresponding increase in unmethylated preproinsulin (PPI) DNA in serum. Here, we report the development of a novel assay using dual fluorescent-probe multiplex PCR (TaqMan) to detect differential methylation of circulating PPI DNA. Key assay features include low background signals, linear assay output across a large range of values, and simultaneous detection of methylated and unmethylated PPI DNA in a single reaction. We defined the "unmethylation index" as a summary parameter that reflects the relative amounts of unmethylated vs methylated PPI DNA. To validate this assay's ability to detect β-cell death in vivo, we measured the unmethylation index in the serum of diabetic mouse models, including high- and multiple low-dose streptozotocin-induced diabetes, and the nonobese diabetic mouse model of type 1 diabetes. Our data show a significantly increased unmethylation index concordant with the known timeline of β-cell death that precedes the onset of hyperglycemia. Subsequently, we observed a decrease in the unmethylation index following diabetes development, likely reflecting the absence of further β-cell death in the pancreas. We conclude that simultaneous measurement of methylated and unmethylated PPI DNA using the multiplex PCR method described here is a readily available and sensitive indicator of dying β-cells that may be useful to track diabetes progression and response to therapeutic intervention.

Pitting and Bending Fatigue Evaluations of a New Case-Carburized Gear Steel (2007)

The power density of a gearbox is an important consideration for many applications and is especially important for gearboxes used on aircraft. One approach to improving power density of gearing is to improve the steel properties by design of the alloy. The alloy tested in this work was designed to be case-carburized with surface hardness of Rockwell C66 after hardening. Test gear performance was evaluated using surface fatigue tests and single-tooth bending fatigue tests. The performance of gears made from the new alloy was compared to the performance of gears made from two alloys currently used for aviation gearing. The new alloy exhibited significantly better performance in surface fatigue testing, demonstrating the value of the improved properties in the case layer. However, the alloy exhibited lesser performance in single-tooth bending fatigue testing. The fracture toughness of the tested gears was insufficient for use in aircraft applications as judged by the behavior exhibited during the single tooth bending tests. This study quantified the performance of the new alloy and has provided guidance for the design and development of next generation gear steels.

DETERMINATION OF IN SITU SHEAR WAVE VELOCITIES FROM SPECTRAL ANALYSIS OF SURFACE WAVES (1982)

A method for determining elastic moduli at soil and pavement sites was proposed and tested. Surface receivers were utilized to evaluate the Rayleigh wave motion created by a vertical, impulsive source that could excite a wide range of frequencies with a single impact. Analysis was facilitated by using a portable spectral analyzer to study the magnitude and phase of the frequency content of the recorded wave pulse. Results from field testing at two flexible pavement sites and two soil sites indicate that the spectral analysis of surface waves provides an accurate estimation of the velocity (and hence modulus) profile at a site. Moduli calculated from wave propagation velocities were generally comparable to moduli calculated by deflection measurements from Dynaflect testing. (FHWA)
