A computing architecture composed of field‐coupled single domain nanomagnets clocked by magnetic field (2003)

Abstract Next neighbour field coupling of nanodevices is emerging as an alternative way to integrate nanoelectronic devices ( Nanotechnology 1993; 4 : 49). In this paper, integrated circuits composed of single domain nanomagnets are proposed. New magnetic field‐coupled devices with multiple equilibrium states are introduced. The devices are made locally active by exposing them to external magnetic fields. Non‐reciprocity is achieved by proper design of the nanomagnet's shape together with its clocking. We demonstrate that (i) digital signal can propagate along a line of coupled single domain nanomagnets; (ii) and a family of logic circuits (inverter, majority gate, etc.) can be realized. Based on these observations we envision a new nanoelectronic computing architecture as a two‐dimensional array of field‐coupled nanomagnets. We estimate an integration density of 10 10 device/cm 2 , few hundred MHz operation speed, straightforward fabrication technology and robust operation in a wide temperature range.

Development of a Guided Soft Target for Crash Avoidance Technology Evaluation (2011)

<div class="section abstract"><div class="htmlview paragraph">As Advanced Crash Avoidance Technologies (ACATs) such as Forward Collision Warning (FCW), Crash Imminent Braking Systems and other advanced technologies continue to be developed, the need for full-scale test methodologies which can minimize hazards to test personnel and damage to equipment has rapidly increased. The challenge of evaluating such ACAT systems is twofold. First, the evaluation system must be able to deliver a potential Collision Partner (CP) reliably and precisely along a trajectory which would ultimately result in a crash in a variety of configurations, such as rear-ends, head-ons, crossing paths, and sideswipes. Second, and more importantly, the collision partner must not pose a substantial physical risk to the test driver, other test personnel, equipment, or to test vehicles in the event that the collision is not avoided.</div><div class="htmlview paragraph">A Guided Soft Target (GST) system has been developed to provide a versatile test methodology for the evaluation of such crash avoidance technologies. This system can be used to replicate a wide range of crash scenarios while minimizing physical risk. The GST system comprises a soft target vehicle or pedestrian form, a programmable, autonomously guided, self-propelled Dynamic Motion Element (DME) and a wireless computer network. The system accommodates virtually any type of collision between the GST and the subject vehicle, and performs closed-loop control to ensure that the GST arrives at the intended collision point at the same instant in time as the subject vehicle. In another mode, the GST arrives at the target location at a specified time and with a specified speed.</div></div>
Rapid changes of heat and desiccation tolerance correlated with changes of trehalose content in <i>Saccharomyces cerevisiae</i> cells subjected to temperature shifts (1987)

The trehalose content of exponentially growing Saccharomyces cerevisiae cells rapidly increased in response to a temperature shift from 27 to 40 degrees C and decreased again when the temperature was shifted back from 40 to 27 degrees C. These changes were closely correlated with increases and decreases in the thermotolerance and desiccation tolerance of the cells. Our results support the hypothesis that trehalose functions as a protectant against heat and desiccation.
A phase I trial of ISIS 2503, an antisense inhibitor of H-ras, in combination with gemcitabine in patients with advanced cancer. (2003)

The combination of gemcitabine and ISIS 2503 was well tolerated and clinically active in this group of heavily pretreated patients. The recommended Phase II dose of gemcitabine (1000 mg/m(2)) and ISIS 2503 (6 mg/kg/day) warrants additional evaluation.
Fear of frying electromagnetic weapons threaten our data networks. Here's how to stop them (2014)

In the 2001 action movie Ocean's Eleven,criminals use an electromagnetic weapon to black out a portion of Las Vegas. Very futuristic, you may say, but the threat is real and growing. The problem is growing because the technology available to attackers has improved even as the technology being attacked has become more vulnerable. Our infrastructure increasingly depends on closely integrated, high-speed electronic systems operating at low internal voltages. That means they can be laid low by short, sharp pulses high in voltage but low in energy-output that can now be generated by a machine the size of a suitcase, batteries included.

The future of small bowel transplantation. (1995)

Although transplantation of solid organs such as kidney and liver have been established since the 1970s and 1980s, the future of small bowel transplantation as treatment for intestinal fail- ure is only just evolving. Early clinical experience was almost universally unsuccessful but recent developments in surgical technique, immunosuppression, and postoperative man- agement have improved outcome with a 50% survival in at least 100 operations.'
Subcellular localization of epitope-tagged neurotrophins in neuroendocrine cells (1998)

A growing body of evidence suggests that neurotrophins (NTs) play a critical role in synaptic plasticity and other activity dependent processes in the CNS. Release of these growth factors by neurons and neuroendocrine cells was recently shown to occur via the regulated secretory pathway, representing a possible mechanism for preferentially supplying NTs locally to active synapses. However, the identity and characteristics of the intracellular storage compartment for NTs undergoing stimulus-coupled secretion remains controversial. As a step towards addressing these issues we have investigated the subcellular localization of epitope-tagged nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), and neurotrophin-3 (NT-3) in neuroendocrine cells. Placement of the myc-epitope tag at the neurotrophin carboxy terminus did not affect essential properties of the NTs such as their ability to induce Trk tyrosine phosphorylation or their sorting into the regulated secretory pathway in PC12 and AtT-20 neuroendocrine cells. Epitope-tagged NTs colocalize with dense core vesicle (DCV)-markers at the light microscopic level in both cell lines investigated. Furthermore, at an EM level immunoreactivity (IR) for myc-tagged NGF was found over dense core granules (DCGs) in PC12 cells. These data provide evidence that NTs can be stored in DCVs in neuronal model cell lines and, potentially, in neurons as well.

<title>Optical nanocluster microchips for human diagnostics</title> (1999)

Metal clusters excited by light exhibit high local field enhancement and nanoscale resonant behavior. Absorptive properties of these metal clusters bound to a surface are the basis of various new and highly promising setups to transduce biorecognitive interactions into an optical signal. Multilayered highly resonant systems had been proposed and recently demonstrated employing a metal mirror, a nanometric polymer distance layer, a biomolecule interaction layer and biorecognitively bound metal nano clusters. The optochips clearly exhibit strong reflection minima induced by the resonant behavior of the metal cluster layer. At least one narrow reflection minimum can be shifted to the red or infra red spectral range and therefore far away from spherical gold colloids (less than 520 nm) and human plasma absorption. The setup enabled us to replace conventional binding assays (like ELISA) overcoming the various technological limits as there are multiple incubation steps, harmful reagents and spatial resolution. A modified setup (the metal island coated swelling polymer over mirror system) employing an optical thin-layer system consisting of a metal mirror, an active analyte-induced swelling polymer, and a metal cluster (island) film as the topmost layer was used to transduce human plasma ion concentrations.
Designing Audio Equalization Filters by Deep Neural Networks (2020)

Audio equalization is an active research topic aiming at improving the audio quality of a loudspeaker system by correcting the overall frequency response using linear filters. The estimation of their coefficients is not an easy task, especially in binaural and multipoint scenarios, due to the contribution of multiple impulse responses to each listening point. This paper presents a deep learning approach for tuning filter coefficients employing three different neural networks architectures—the Multilayer Perceptron, the Convolutional Neural Network, and the Convolutional Autoencoder. Suitable loss functions are proposed for each architecture, and are formulated in terms of spectral Euclidean distance. The experiments were conducted in the automotive scenario, considering several loudspeakers and microphones. The obtained results show that deep learning techniques give superior performance compared to baseline methods, achieving almost flat magnitude frequency response.
Submicrometer-gate MOSFET's by the use of focused-ion-beam exposure and a dry development technique (1987)

Resist patterns as small as 0.1 µm were fabricated by the irradiation of a gallium focused ion beam followed by an oxygen plasma development. The measured width of the patterns fabricated by this technique was in good agreement with the designed linewidth in the sub-half-micrometer region, n-channel Si MOSFET's with 0.3-0.8-µm gates were fabricated by the use of this technique. These results, accompanied by the fabricated and demonstrated performance of a ring oscillator, showed the feasibility of focused-ion-beam lithography.

Metabolism of arachidonic acid by pancreatic acini: relation to amylase secretion (1982)

Isolated guinea pig pancreatic acini were incubated with exogenous [14C]arachidonic acid (10 microM) at 37 degrees C for 3 min. The lipids were extracted and separated by thin-layer chromatography. Radiolabeled metabolites were identified by comigration with standards: 0.024% of the recovered radioactivity comigrated with prostaglandin E2 (PGE2), 0.016% comigrated with PGF2 alpha, 4.9% was incorporated into triglycerides, 1.8% was incorporated into phospholipids, and 93.2% remained as arachidonic acid. The synthesis of PGE2 and PGF2 alpha was inhibited by indomethacin (ID50, 30 nM). Simultaneous addition of carbachol or caerulein with the [14C]arachidonic acid did not alter the metabolism of the arachidonate. Further studies were done on the role of arachidonate metabolites in the secretion of amylase. Exogenously added PGE2 and PGF2 alpha (0.3-100 nM) did not induce amylase secretion from isolated acini. Incubation of isolated acini with indomethacin (0.1-28 microM) did not inhibit the release of amylase induced by carbachol or caerulein. From these data, we conclude that isolated guinea pig pancreatic acini are capable of converting a small percentage of exogenous arachidonate to PGE2 and PGF2 alpha. However, there is no evidence for a role of these compounds in stimulus-secretion coupling.
Exact traveling wave solution for nonlinear D-S equation (2010)

Synthetic aperture FM-CW radar applied to the detection of objects buried in snowpack (1994)

Presents the principle of synthetic aperture frequency modulated continuous wave (FM-CW) radar and demonstrates the detection results of several objects buried in natural snowpack using the radar system. First, the synthetic aperture technique is explained with emphasis placed on showing that the Fourier transformed beat signal obtained by the FM-CW radar is equivalent to one kind of Fresnel hologram, which leads the authors to use the SAR technique. Then a radar system operative in the microwave L-band is explored to detect objects buried in natural snowpack. Several detection results are presented demonstrating the potential capability of high resolution imaging in the azimuth direction, comparing with real aperture images.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
SiGe bipolar technology for mixed digital and analogue RF applications (2002)

A SiGe bipolar technology with a low-resistivity base integrated into a double-polysilicon self-aligned transistor has been developed. A transit frequency of 85 GHz, a maximum oscillation frequency of 128 GHz, 6.8 ps gate delay, and a minimum noise figure of 1.2 dB at 10 GHz demonstrate balanced transistor performance. With an 88 GHz dynamic frequency divider and a 12 GHz low noise amplifier with 1.9 dB noise figure, state-of-the-art results for digital as well as analogue applications are achieved.
Isolation and Characterization of a Genetically Tractable Photoautotrophic Fe(II)-Oxidizing Bacterium, <i>Rhodopseudomonas palustris</i> Strain TIE-1 (2005)

We report the isolation and characterization of a phototrophic ferrous iron [Fe(II)]-oxidizing bacterium named TIE-1 that differs from other Fe(II)-oxidizing phototrophs in that it is genetically tractable. Under anaerobic conditions, TIE-1 grows photoautotrophically with Fe(II), H2, or thiosulfate as the electron donor and photoheterotrophically with a variety of organic carbon sources. TIE-1 also grows chemoheterotrophically in the dark. This isolate appears to be a new strain of the purple nonsulfur bacterial species Rhodopseudomonas palustris, based on physiological and phylogenetic analysis. Fe(II) oxidation is optimal at pH 6.5 to 6.9. The mineral products of Fe(II) oxidation are pH dependent: below pH 7.0 goethite (alpha-FeOOH) forms, and above pH 7.2 magnetite (Fe3O4) forms. TIE-1 forms colonies on agar plates and is sensitive to a variety of antibiotics. A hyperactive mariner transposon is capable of random insertion into the chromosome with a transposition frequency of approximately 10(-5). To identify components involved in phototrophic Fe(II) oxidation, mutants of TIE-1 were generated by transposon mutagenesis and screened for defects in Fe(II) oxidation in a cell suspension assay. Among approximately 12,000 mutants screened, 6 were identified that are specifically impaired in Fe(II) oxidation. Five of these mutants have independent disruptions in a gene that is predicted to encode an integral membrane protein that appears to be part of an ABC transport system; the sixth mutant has an insertion in a gene that is a homolog of CobS, an enzyme involved in cobalamin (vitamin B12) biosynthesis.
Laboratory Bioassay for Resistance in Corn to Fall Armyworm (Lepidoptera: Noctuidae) and Southwestern Corn Borer (Lepidoptera: Pyralidae) (1990)

Inbred lines of corn, Zea mays L., were evaluated for resistance to leaf feeding by the fall armyworm, Spodoptera frugiperda (J. E. Smith), and southwestern corn borer, Diatraea grandiosella Dyar, in field and laboratory experiments. For the laboratory bioassays, diets were prepared from lyophilized whorl tissue of field grown plants of resistant and susceptible corn inbred lines. To prepare the diets, 11 g lyophilized tissue was stirred into a mixture of 250 ml distilled water, 2 g agar, 12.5 mg gentamicin sulfate, 132 mg sorbic, and 528 mg ascorbic acid that had been heated to 82°C and poured into 30-ml plastic cups. Cups were infested with two neonate larvae each. Fall armyworm larvae reared for 10 d on diets containing tissue of resistant inbred lines weighed 60% less than those reared on diets containing susceptible inbred tissue. Southwestern corn borer larvae reared for 14 d on whorl tissue from resistant inbred lines weighed 50% less than those reared on susceptible tissue. The laboratory bioassay satisfactorily differentiated among resistant and susceptible corn inbreds.
Chemical mechanisms of Schottky barrier formation (1979)

Ultrahigh vacuum studies of reactive and unreactive metals on a wide range of semiconductors reveal new systematics of Schottky barrier formation. Surface work function, band bending, and chemical bonding measurements indicate several qualitatively different mechanisms of barrier formation, each determined by the degree of interface chemical reactivity. In general, the Schottky barrier formation can be characterized by a twofold process—local charge redistribution plus surface space charge transfer. The specific interface bonding determines the sign and magnitude of the local charge redistribution. Correlations between these interface phenomena and deviations from ideal barrier heights suggest a framework based on interface bonding for determining Schottky barrier heights.
CONVOLUTION AND TIME INVERSION USING PARAMETRIC INTERACTIONS OF ACOUSTIC SURFACE WAVES (1971)

We report on the observation of acoustic convolution, time inversion, and electronically variable delay in real time using 105- and 220-MHz surface acoustic waves in YZ-cut LiNbO3 delay rods. The time inversion is a special case of correlation, where a short ``pip'' pulse will create a reflection in time for the injected input signal pulse. The conversion losses in the processing were 64–74 dB.
Replication and Transmission of H9N2 Influenza Viruses in Ferrets: Evaluation of Pandemic Potential (2008)

H9N2 avian influenza A viruses are endemic in poultry of many Eurasian countries and have caused repeated human infections in Asia since 1998. To evaluate the potential threat of H9N2 viruses to humans, we investigated the replication and transmission efficiency of H9N2 viruses in the ferret model. Five wild-type (WT) H9N2 viruses, isolated from different avian species from 1988 through 2003, were tested in vivo and found to replicate in ferrets. However these viruses achieved mild peak viral titers in nasal washes when compared to those observed with a human H3N2 virus. Two of these H9N2 viruses transmitted to direct contact ferrets, however no aerosol transmission was detected in the virus displaying the most efficient direct contact transmission. A leucine (Leu) residue at amino acid position 226 in the hemagglutinin (HA) receptor-binding site (RBS), responsible for human virus-like receptor specificity, was found to be important for the transmission of the H9N2 viruses in ferrets. In addition, an H9N2 avian-human reassortant virus, which contains the surface glycoprotein genes from an H9N2 virus and the six internal genes of a human H3N2 virus, showed enhanced replication and efficient transmission to direct contacts. Although no aerosol transmission was observed, the virus replicated in multiple respiratory tissues and induced clinical signs similar to those observed with the parental human H3N2 virus. Our results suggest that the establishment and prevalence of H9N2 viruses in poultry pose a significant threat for humans.
Adding implicit invocation to traditional programming languages (1993)

Implicit invocation based on event broadcasting is an increasingly important technique for integrating systems. The authors broaden the class of systems that can benefit from this approach by showing how to augment general-purpose programming languages with facilities for implicit invocation. They illustrate the approach in the context of the Ada language. Attempts to add implicit invocation to standard languages raise a number of design decisions that can have a significant impact on the properties of the mechanism and on its usability. These design considerations are highlighted so that any similar attempt to add implicit invocation to a strongly-typed, procedure-oriented programming language can benefit from this work. >
Physiological Studies of an Oligosporogenous Strain of <i>Bacillus popilliae</i> (1971)

A relatively small but consistent increase in the frequency of spore formation by an oligosporogenous strain of Bacillus popilliae (NRRL B-2309M) was obtained by adding 0.1% sodium pyruvate to the sporulation medium. The frequency of spore formation was essentially the same when a low level of glucose, trehalose, or glucose-6-phosphate or a high level of alpha-methyl-d-mannoside was added as the carbon and energy source. Many other variations in the cultural medium and cultural conditions failed to enhance spore formation of 2309M, and no spores were found in four asporogenic strains under any of the conditions tried. There were no significant differences between the 2309M strain and three nonsporeforming cultures with respect to (i) the rate and extent of growth, (ii) the rates of glucose utilization, or (iii) volatile acid production and utilization. None of the cultures tested was found to produce detectable levels of extracellular protease or an antibiotic. The only consistent marker found associated with spore formation was the development of catalase activity, and this activity was stimulated by heating at 80 C for 10 min. This was not found unless morphological evidence of spore formation was observed. The germination of the spores formed by 2309M in vitro was stimulated by heat shock and by the addition of pyruvate to the germination medium.
Studies of Amyloid <i>β</i>‐Protein Precursor Expression in Alzheimer's Disease (1991)

The generation of the beta/A4 peptide and its accumulation into insoluble amyloid deposits represent key events in the neuropathologic process of Alzheimer's disease (AD). This posit has gained further support from recent reports that beta/A4 is directly responsible for the death of neurons. Potential therapies for AD aimed at abating the production of beta/A4 will require the basic knowledge of where it comes from. The 4.2-kD peptide is derived from a much larger amyloid precursor protein (APP) encoded by a gene that produces multiple transcripts. Employing in situ hybridization with biotinylated oligonucleotide probes, we set out to define which forms of the precursor are synthesized in affected regions of AD brain (e.g., hippocampal formation) and to determine the cell populations responsible for their manufacture.

Natura visionaria, palpitante di emozioni e pensieri, è la pittura di Raimondo Sirotti. Artista ligure, fra i più rappresentativi dell'informale, che da oltre cinquanta anni nutre la tavolozza di materia cosmica, di terra e acqua, vento e luce. Pittura passionale che sconosce la geometria dell'astrazione e l'impassibilità della mente, tesa a significare, con colori e segni, i turbini dell'anima e le pulsioni dei sensi, la verità cioè dell'uomo posto dinanzi all'enigma dell'universo e al mistero dell'io.
