Experimental Study of Signal Stability on Triple-Layer Perpendicular Recording Media (1997)

Signal stability against the effect of stray fields and thermal relaxation has been experimentally studied for CoCrTa/CoZrNb/CoSm triple-layer (TL) perpendicular recording media. Readback signals are stable in stray fields within 5 Oe. However, signal decay occurs at stray fields larger than 6 Oe. The cause of signal decay is domain wall motions in the CoZrNb layers and magnified fields from the main pole in a single-pole head. Thermal relaxation is not detected at recording densities higher than 100 kfci, while it increases at lower recording densities with a smaller Hc⊥ or Mr⊥/Ms value of the CoCrTa perpendicular layer. Although we previously demonstrated that TL media have higher signal stability compared with conventional double-layer media, the TL media require further improvements and optimization of each layer before they can be applied to practical use.
Thermal Electrification and Removal of Electrons by Solid Particles in a Gas (1963)

Dust particles of a refractory material may provide a method for the removal of free electrons in a gas plasma, provided that the thermionic emission from the dust particles is negligible. A study was made of thermionic emission from solid particles in thermodynamic equilibrium with a gas.

Deuterium isotope effects on the product partitioning of fluoromethylglyoxal by glyoxalase I. Proof of a proton transfer mechanism. (1981)

Fluoromethylglyoxal in the presence of glutathione has been shown to undergo a novel glyoxalase I-catalyzed product partitioning to S-fluorolactoylglutathione and S-pyruvylglutathione with fluoride elimination. While the partition ratio (fluoride eliminated/total fluoride) was insensitive to pH 5.5-7.5 and concentrations of substrate and glyoxalase I, it was species-dependent. When [1-2H]fluoromethylglyoxal was reacted with glyoxalase I, an increase in the partition ratio and retention of deuterium in the product fluorolactate was observed. This result can only be explained by a selective primary isotope effect on the protonation of an enediol intermediate relative to fluoride elimination.

A Multi-world Intelligent Genetic Algorithm to Interactively Optimize Large-scale TSP (2006)

To optimize large-scale distribution networks, solving about 1000 middle scale (around 40 cities) TSPs (traveling salesman problems) within an interactive length of time (max. 30 seconds) is required. Yet, expert-level (less than 3% of errors) accuracy is necessary. To realize the above requirements, a multi-world intelligent GA method was developed. This method combines a high-speed GA with an intelligent GA holding problem-oriented knowledge that is effective for some special location patterns. If conventional methods were applied, solutions for more than 20 out of 20,000 cases were below expert-level accuracy. However, the developed method could solve all of 20,000 cases at expert-level
<i>Puccinia acroptili</i> on Russian Knapweed in Colorado, Montana, and Wyoming (2006)

Acroptilon repens (L.) DC. (Russian knapweed) is a long-lived perennial weed from central Asia that is widely distributed in the western United States (U.S.). Recently, accessions of a rust disease were collected from Colorado (CO), Montana (MT), and Wyoming (WY) for comparison with Eurasian isolates. U.S. accessions had two-celled teliospores with slight constrictions in the middle and urediniospores with three germ pores ± equatorial in location. Urediniospores were (state, width × length, [n = 100]): CO, 16.4 to 25.7 × 19.2 to 27.0 μm; MT, 18.4 to 23.1 × 17.4 to 24.6 μm; and WY, 18.0 to 26.2 × 20.2 to 26.7 μm. These were similar to those of 16.6 to 25.7 × 21.2 to 28.0 μm from two New Mexican (NM) herbarium specimens (BPI Nos. 1107952 and 1110177) (1). Teliospores measured 19.9 to 27.7 × 29.8 to 47.4 μm, 17.4 to 26.0 × 32.4 to 44.2 μm, 16.5 to 27.5 × 29.4 to 45.7 μm, and 18.7 to 27.6 × 31.0 to 46.4 μm for CO, MT, WY, and NM accessions, respectively. These rust isolates have been identified as Puccinia acroptili Syd. on the basis of host plant record and spore morphology (2). To our knowledge, this is the first record of P. acroptili in CO, MT, and WY. Besides NM, P. acroptili has been reported in North America from California, British Columbia, and Saskatchewan.

The clinical and basic pharmacology of mivacurium: a short‐acting nondepolarizing benzylisoquinolinium diester neuromuscular blocking drug (1995)

Mivacurium is a benzylisoquinolinium diester. The drug is a nondepolarizing relaxant which is hydrolysed by plasma cholinesterase at 70-88% of the rate of suxamethonium. Enzymatic hydrolysis gives the drug its short duration of action. The length of paralysis is about 2-2.5 times that of suxamethonium and one-half to one-third that of the intermediate-acting nondepolarizers. The development of mivacurium represents a collaboration between industrial pharmacologists and chemists at Burroughs Wellcome Co. (USA) and investigators at the Massachusetts General Hospital, Boston, MA, USA.
Inside-out: Reflecting on your inner state (2013)

We present a novel sensor system and interface that enables an individual to capture and reflect on their daily activities. The wearable system gathers both physiological responses and visual context through the use of a wearable biosensor and a cell-phone camera, respectively. Collected information is locally stored and securely transmitted to a novel digital mirror. Through interactive visualizations, this interface allows users to reflect not only on their outer appearance but also on their inner physiological responses to daily activities. Finally, we illustrate how combining a time record of physiological data with visual contextual information can improve and enhance the experience of reflection in many real-life scenarios, and serve as a useful tool for behavior science and therapy.
Devitrification products of rapidly solidified Ni-Nb amorphous alloys. (1990)

Rapid solidification of Ni-Nb alloys promotes the formation of amorphous structure. Preliminary results indicate promising elastic properties and high fracture strength for the metallic glass. Knowledge of the thermal stability of the amorphus alloy and the changes in properties with temperature is therefore of prime importance. In this work rapidly solidified Ni-Nb alloys were analyzed with transmission electron microscopy (TEM) during in-situ heating experiments and after isothermal annealing of bulk samples. Differential thermal analysis (DTA), scanning electron microscopy (SEM) and x-ray diffraction (XRD) techniques were also used to characterize both the solidification and devitrification sequences. Samples of Ni-44 at.% Nb were electromagnetically levitated, melted, and rapidly solidified by splatquenching between two copper chill plates. The resulting samples were 100 to 200 μm thick discs of 2 to 3 cm diameter. TEM specimens were either ion-milled or alternatively electropolished in a methanol-10% sulphuric acid solution at 20 V and −40°C.
TH‐C‐210A‐03: X‐Ray Based Imaging in Neurovascular Intervention — Requirements and Challenges (2009)

In the US, 795,000 people are expected to have a new or recurrent stroke in 2009. Ischemic stroke , which accounts for more than 80% of all strokes, carries a severe toll being the 3 rd cause of death and the leading cause of disability. The cost of stroke, both direct and indirect, will exceed $60 billion this year alone. Hemorrhagic stroke on the other hand originates from rupture of brain aneurysms, which cause the vast majority of subarachnoid hemorrhage, a devastating medical emergency that affects more than 30,000 Americans each year and causes substantial disability and death. As in the coronary and peripheral vascular system, surgical treatment and medical management is progressively replaced by minimally invasive endovascular treatment . In recent years we have witnessed a rapid advancement in stent and stent‐like technology. Stents do not only serve for a combined intra‐ and extrasaccular treatment of challenging aneurysms, but assist the revascularization in acute and chronic ischemic conditions of the neurovascular system. In the Neuroangiography Suite x‐ray based imaging for guidance of devices and for monitoring brain perfusion during the intervention has experienced a quantum leap. Replacement of Image Intensifiers (II) with Flat Panel Detectors (FD) has enabled to increase the rotational speed of the system and its use as cone beam CT. Today angiography techniques do not only serve to characterize local flow alterations induced by vessel implants, but also study brain perfusion prior and during revascularization maneuvers. Detailed information of vascular structures is provided in conjunction with the surrounding brain tissue and vessel wall . Imaging of temporary or permanent implants is available with high resolution that is vital for a precise placement, treatment efficacy and patient safety.
The Shaker-like potassium channels of the mouse rod bipolar cell and their contributions to the membrane current (1995)

RT PCR on mRNA from enzymatically dissociated, isolated bipolar cells showed that these neurons express the Shaker-like K+ channels Kv1.1, Kv1.2, and Kv1.3. Immunohistochemical localization showed each channel to have a unique subcellular distribution: Kv1.1 immunoreactivity was detected in the dendrites and axons terminal, whereas Kv1.2 and Kv1.3 subunits were localized to the axon and the postsynaptic membrane of the rod ribbon synapse, respectively. Whole-cell patch-clamp recordings indicated that the activation voltage of the delayed rectifier current of the isolated bipolar cell and the inhibitory constants for current blockade by TEA, 4-AP, and Ba2+ were similar to these same properties measured for Kv1.1 expressed in oocytes. However, the TEA and 4-AP inhibitory constants for the bipolar cell current differed from the inhibitory constants for Kv1.2 or Kv1.3. These results suggest that the current of the isolated rod bipolar cell is most similar to Kv1.1 but that all three channels may function in the intact retina to allow complex modulation of retinal synaptic signals.
OPERATION SANDSTONE. Nuclear Explosions. 1948. Scientific Director's Report of Atomic Weapon Tests. Annex 7, Part 2. Technical Photography Measurements. (1950)

Abstract : This report presents a complete analysis of the work done to date on the post-detonation phenomena from the Sandstone films. Due to the extreme changes in brightness after detonation, a large number of frames from each film had improper exposures. The Fastax films were most useful during the first thirty milliseconds since the shorter exposure time limited the dynamic error and time could be measured accurately from the time markers on the film. The Mitchell films gave good resolution after thirty milliseconds, but the absence of time markers made time measurements uncertain. The lack of a value for the camera-to-aircraft distance or accurate position markers on the water surface limit the measurement to accuracies of less than + or - 100 meters on the best of the aerial photographs. A number of reports by the J-7 Photographic Analysis Sub-group have been incorporated into this account. The reports used are: LAMS-921 -- Analysis of Fireball Growth at Sandstone; LAB-J-7 -- Analysis of Spike Growth and Fireball Height at Sandstone; LAB-J-705 -- Mach Stem Height versus Horizontal Distance Determinations; and LAB-J-786 -- Evaluations of the Errors in the LAMS-921 Space-Time Curve.
Missionary to the Malagasy: The Madagascar Diary of the Rev. Charles T. Price, 1875-1877 (1989)

Just married and just ordained, the Rev. C.T. Price provides a fascinating travelogue of his journey by sail from England to Madagascar and of his subsequent trips on church business in that country (1875-1877). The author is a careful chronicler of his daily encounters, a frank commentator of persons and situations, and also an informed observer of conditions in this island kingdom, such as state-church relations, Malagasy custom, local government, or economic life. Needless to say, his account also tells much about missionaries, including himself.
Parenchymal preamyloid and amyloid deposits in the brains of patients with hereditary cerebral hemorrhage with amyloidosis—Dutch type (1990)

Hereditary cerebral hermorrhage with amyloidosis--Dutch type, one of the 'cerebral beta-amyloid diseases', like Alzheimer's disease, is characterized by extensive deposition of amyloid in small cerebral vessels. We investigated the presence of parenchymal beta-protein deposits in two Dutch patients with hereditary cerebral hemorrhage with amyloidosis. Immunostaining with anti-SP28 revealed a full spectrum of these deposits, varying from preamyloid deposits to burned-out plaques. However, their density is less than in Alzheimer's disease, and immunostaining with Alz50 and anti-PHF did not show abnormal neurites in and around amyloid deposits in these two patients.
Live sound loudspeaker array optimization for consistent directional coverage with diffuse radiation characteristics. (2018)

A central aim of sound reinforcement systems is to deliver consistent tonality across a wide audience area. Loudspeaker arrays are commonly used to meet this goal, where the upper and lower frequency bounds that can be spatially controlled are dictated by inter-element spacing and array width, respectively. This work focuses on the calculation of frequency-dependent complex coefficients for each array element using a modified Fourier technique to achieve a frequency-independent radiation pattern across an array’s functional region. In order to ensure efficiency, temporally diffuse impulses are utilized within the optimization procedure to avoid clustering of radiated energy at the center of an array and to provide a diffuse radiated field while maintaining the desired directional characteristics. Example applications for subwoofer arrays are presented, although the technique is applicable to any frequency range across the audible spectrum.
Automated Selection of Active Orbital Spaces (2016)

One of the key challenges of quantum-chemical multi-configuration methods is the necessity to manually select orbitals for the active space. This selection requires both expertise and experience and can therefore impose severe limitations on the applicability of this most general class of ab initio methods. A poor choice of the active orbital space may yield even qualitatively wrong results. This is obviously a severe problem, especially for wave function methods that are designed to be systematically improvable. Here, we show how the iterative nature of the density matrix renormalization group combined with its capability to include up to about 100 orbitals in the active space can be exploited for a systematic assessment and selection of active orbitals. These benefits allow us to implement an automated approach for active orbital space selection, which can turn multi-configuration models into black box approaches.

The 3<sup>rd</sup>degree of biomimetism: associating the cavity effect, Zn<sup>II</sup>coordination and internal base assistance for guest binding and activation (2018)

The synthesis and characterization of a resorcinarene-based tetra(imidazole) ligand is reported. The properties of the corresponding Zn<sup>II</sup> complex are studied in depth, notably by NMR spectroscopy. In MeCN, acid-base titration reveals that one out of the four imidazole arms is hemi-labile and can be selectively protonated, thereby opening a coordination site in the <i>exo</i> position. Quite remarkably, the 4<sup>th</sup> imidazole arm promotes binding of an acidic molecule (a carboxylic acid, a β-diketone or acetamide), by acting as an internal base, which allows guest binding as an anion to the metal center in the <i>endo</i> position. Most importantly, the presence of this labile imidazole arm makes the Zn<sup>II</sup> complex active for the catalyzed hydration of acetonitrile. It is proposed that it acts as a general base for activating a water molecule in the vicinity of the metal center during its nucleophilic attack to the <i>endo</i>-bound MeCN substrate. This system presents a unique degree of biomimetism when considering zinc enzymes: a pocket for guest binding, a similar first coordination sphere, a coordination site available for water activation in the <i>cis</i> position relative to the substrate and finally an internal imidazole residue that plays the role of a general base.
Synthesis, optical anisotropies, polarisabilities and order parameters of 4-cyanophenyl and 4-isothiocyanatophenyl 4′-butylsulfanylbenzoates with oxygen and sulfur substitution in the ester linkage (1995)

The optical anisotropies, polarisabilities, refractive indices and order parameters of 4-cyanophenyl and 4-isothiocyanatophenyl 4′-butylsulfanylbenzoates with oxy- and thin-substitution in all possible combinations in the ester link have been measured and the results are discussed in terms of the position and number of sulfur atoms in the ester linkage. The S-aryl thio- and dithio-benzoates have greater polarisabilities than the corresponding O-aryl esters; the differences between O-aryl and S-aryl thiobenzoates are discussed in terms of the electronegativity and structural changes caused by substitution with sulfur.
Flexible Mild Heaters in Structural Conservation of Paintings: State of the Art and Conceptual Design of a New Carbon Nanotubes-based Heater (2012)

INDEXED BY SCOPUS\nThermal treatments constitute the core in the success for most structural treatments, such as consolidation, treating planar deformations, reinforcing degraded support and others. Among the wide range of devices for thermal treatments of paintings proposed in scientific and technical literature, flexible heaters appear to be the most promising technology, especially for working with large painting or in situ. The present paper provides a comprehensive review of flexible mild heater systems devised for structural conservation of paintings in the last decades, bringing forward the issues related to the instrumentation used for thermal treatments, stressing the importance of accurate control, and the inadequateness of available devices. By highlighting the actual limitations of existing devices, a different approach, which employs Carbon Nanotubes-based flexible heaters, is then proposed in its conceptual form. The design of such device, called IMAT (Intelligent Mobile Accurate Thermo-electrical device), is supported by the European Community in the context of the EC-FP7 Environment Theme (ENV-NMP.2011.2.2-5) into a three-year project started on November 2011.
Cyclometalated Platinum(II) Complexes of Lepidine-Based Ligands as Highly Efficient Electrophosphors (2010)

A new series of lepidine-containing-ligand-based cyclometalated platinum(II) complexes 1−7 with general formula [Pt(L)acac] (L = lepidine-based ligand, acac = acetylacetonate) have been synthesized. The complexes have been characterized using spectral and electrochemical techniques. The single-crystal X-ray structures of complexes 2 and 5 have been successfully determined. The effects of substituents on the electronic features and redox potentials of the cyclometalated phenyl ring of the complexes are discussed. Complexes 1−7 are highly phosphorescent in fluid as well as in solid state, covering a rather broad spectral range from yellow to saturated red. These complexes were successfully used as a dopant material to fabricate the electroluminescent device, ITO/NPB (40 nm)/CBP-doped Pt complex (5 wt %) (20 nm)/BCP (10 nm)/Alq3 (20 nm)/LiF (1 nm)/Al (150 nm), which exhibits very promising performance. The device doped with 5 wt % 3 produced a maximum external quantum efficiency of 15.2% with a maximum brightness of 26847 cd m−2 and corresponds to a luminance efficiency of 29.83 cd A−1.
Testing Genetic Linkage with Relative Pairs and Covariates by Quasi-Likelihood Score Statistics (2007)

Although application of our methods to a prostate cancer linkage study did not find any critical covariates in our data, the results illustrate the utility and interpretation of our methods, and suggest, nonetheless, that our methods will be useful for a broad range of genetic linkage heterogeneity analyses.
