OmniTRACS: a commercial Ku-band mobile satellite terminal and its applicability to military mobile terminals (2003)

The technical characteristics of the OmniTRACS system are described. This system is the first operational mobile Ku-band satellite communications system and provides two-way message and position determination service to mobile terminals using existing Ku-band satellites. Interference to and from the system is minimized by the use of spread-spectrum techniques, together with low-power, low-data-rate transmissions. The applicability of this technology to implement a military mobile terminal operating over existing SHF satellites is also presented. Features discussed include the return- and forward-link modulating signals, the return-link power density, and the mobile-terminal hardware.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Silence of the Sexes: Gender Inversion in Jonathan Demme's The Silence of the Lambs (2009)

"Silence of the Sexes: Gender Inversion in Jonathan Demme's The Silence of the Lambs" focuses on the role gender plays in and between the characters of Clarice Starling, Buffalo Bill, and Dr. Hannibal Lecter in Jonathan Demme's film The Silence of the Lambs (1991). Specifically, the paper focuses on the struggle for Clarice to masculinize herself to be accepted in her career, and the struggle for Buffalo Bill to feminize himself in order to accept himself. The paper then discusses the inability for the one person to succeed while the other is still an obstacle in his or her path, which then brings in the role of the phallus for Clarice, who otherwise lacks the symbolic authority encoded in the phallus.
Nanometer-thin titania films with SAM-level stiction and superior wear resistance for reliable MEMS performance (2004)

Most MEMS devices involving contacting surfaces suffer from stiction and wear. While the development of self-assembled monolayer (SAM)-based processes has virtually eliminated stiction, wear remains a serious reliability issue. In this paper, the use of titania ultra-thin films as a means to reduce both stiction and wear is reported. Atomic layer deposition (ALD) is used for the film growth in order to ensure a uniform and conformal coating, effectively encapsulating the released polysilicon microelectromechanical systems (MEMS) devices. The application of 10-nm thin titania coating is shown to result in improved reliability of test microdevices. To further improve reliability, a vapor phase SAM coating is applied to TiO/sub 2/ encapsulated micromachines. Results on the tribological properties of both TiO/sub 2/-and SAM coated TiO/sub 2/-encapsulated microdevices are presented.
Thioredoxin reductase (2000)

Thioredoxin reductase (EC 1.6.4.5) is a widely distributed flavoprotein that catalyzes the NADPH-dependent reduction of thioredoxin. Thioredoxin plays several key roles in maintaining the redox environment of the cell. Like all members of the enzyme family that includes lipoamide dehydrogenase, glutathione reductase and mercuric reductase, thioredoxin reductase contains a redox active disulfide adjacent to the flavin ring. Evolution has produced two forms of thioredoxin reductase, a protein in prokaryotes, archaea and lower eukaryotes having a Mr of 35 000, and a protein in higher eukaryotes having a Mr of 55 000. Reducing equivalents are transferred from the apolar flavin binding site to the protein substrate by distinct mechanisms in the two forms of thioredoxin reductase. In the low Mr enzyme, interconversion between two conformations occurs twice in each catalytic cycle. After reduction of the disulfide by the flavin, the pyridine nucleotide domain must rotate with respect to the flavin domain in order to expose the nascent dithiol for reaction with thioredoxin; this motion repositions the pyridine ring adjacent to the flavin ring. In the high Mr enzyme, a third redox active group shuttles the reducing equivalent from the apolar active site to the protein surface. This group is a second redox active disulfide in thioredoxin reductase from Plasmodium falciparum and a selenenylsulfide in the mammalian enzyme. P. falciparum is the major causative agent of malaria and it is hoped that the chemical difference between the two high Mr forms may be exploited for drug design.
Cloning and characterization of <i>hOGG1</i> , a human homolog of the <i>OGG1</i> gene of <i>Saccharomyces cerevisiae</i> (1997)

The OGG1 gene of Saccharomyces cerevisiae encodes a DNA glycosylase activity that is a functional analog of the Fpg protein from Escherichia coli and excises 7,8-dihydro-8-oxoguanine (8-oxoG) from damaged DNA. The repair of this ubiquitous kind of oxidative damage is essential to prevent mutations both in bacteria and in yeast. A human cDNA clone carrying an ORF displaying homology to the yeast protein was identified. The predicted protein has 345 amino acids and a molecular mass of 39 kDa. This protein shares a 38% sequence identity with the yeast Ogg1 protein, adding this novel human gene product to the growing family of enzymes that the repair of oxidatively damaged bases and are related to the E. coli endonuclease III. Northern blot analysis indicates that this gene, localized to chromosome 3p25, is ubiquitously expressed in human tissues. The cloned coding sequence was expressed in an E. coli strain that carried a disrupted fpg gene, the bacterial functional analog of OGG1. Cell-free extracts from these cultures displayed a specific lyase activity on duplex DNA that carried an 8-oxoG/C base pair. The products of the reaction are consistent with an enzymatic activity like the one displayed by the yeast Ogg1. Analysis of the substrate specificity reveals a very strong preference for DNA fragments harboring 8-oxoG/C base pairs. The pattern of specificity correlates well with the one found for the yeast enzyme. Moreover, when the human coding sequence was expressed in a yeast strain mutant in OGG1 it was able to complement the spontaneous mutator phenotype. These results make this novel gene (hOGG1) a strong candidate for the human homolog of the yeast OGG1 and suggest an important role of its product in the protection of the genome from the mutagenic effects of the oxidatively damaged purines.

Solving the singularity problem of non-redundant manipulators by constraint optimization (2003)

A solution to the singularity problem of a non-redundant robot is proposed by reformulating the inverse kinematic problem as a constraint optimization problem. The main idea is to allow a cartesian error in a given subspace in the vicinity of a singularity and to minimize this error subject to operational constraints such as maximum motor speeds. As a result, in every sampling instant a series of linear least squares problems with linear equality and inequality constraints have to be solved. This task can be carried out on a Pentium processor within a few milliseconds. The new method is demonstrated by real experiments with an industrial robot.
An improved active suspension yaw rate control (2002)

The authors previously (2002) gave an insight into the full vehicle suspension model. They proposed a truly decoupled model for the full vehicle suspension consisting of 4 subsystems. The first 3 ones are completely decoupled single input single output systems. They are analogous to, and may be seen as virtual, quarter car suspension models. The fourth subsystem is one for an abstract variable called /spl gamma/ which insures a rational distribution of the 3 virtual suspension efforts to the 4 real ones. The present communication we use this modeling result to propose a new yaw rate control using the active suspension. We first show how /spl gamma/ is related to the yaw rate. Next we reduce the yaw rate control problem to the regulation of a ratio of the front normal forces over the rear ones. The setpoint in this regulation chosen in order to obtain a so-called neutral car. The control design is illustrated through simulations.
Low Alpha-Particle-Emitting Ceramics: What's the Lower Limit? (1979)

Typical semiconductor, ceramic packaging materials, and typical commercial raw materials used in formulating ceramic packaging materials were analyzed for alpha-particle-emission characteristics and for trace uranium and thorium contents. Results indicate the possibilities of achieving low alpha-particle-emitting ceramic substrates, covers, and sealants.

Evaluating a cloud federation ecosystem to reduce carbon footprint by moving computational resources (2015)

Cloud federation is an emerging topic towards new dynamic scenarios in smart ecosystems, where new more flexible energy management strategies are needed than the traditional, in order to optimize mobility and energy efficiency. In this paper we focus both on cloud federation and energy efficiency to enforce a dynamic energy management strategy for the whole ecosystem, in order to reduce carbon dioxide emissions. More specifically, starting from our two-step approach, we evaluate a cloud federation ecosystem by moving computational resources among federated cloud DCs in order to maintain, for a forecast period, the related workload at the best Green Destination (GD) powered by renewable energy sources. To this end we present and discuss two simulated scenarios, and their experimental results, thus to proving the goodness of our approach. Moreover, an energy comparison between the transfer and the maintenance phases for the computational workload is made.
Semiconductor lasers on Si substrates using the technology of bonding by atomic rearrangement (1993)

We demonstrated InGaAs/GaAs strained quantum well lasers on silicon substrates. The epitaxial layers for lasers were first grown on a GaAs substrate and then bonded to a silicon substrate using the technology of bonding by atomic rearrangement. Covalently bonded III-V/Si heterointerface was confirmed by the cross-sectional transmission electron microscopy. The ridge waveguide lasers on Si substrates lasing at about 1 μm wavelength have a 12 mA threshold current and a 56% external quantum efficiency at room temperature, at pulsed condition. Both the threshold current and the external quantum efficiency are close to the values of lasers on GaAs substrates. The technology of bonding by atomic rearrangement will be useful for making optoelectronic integrated circuits on Si.
Ultrafiltration tandem mass spectrometry of estrogens for characterization of structure and affinity for human estrogen receptors (2004)

Although hormone replacement therapy (HRT) is used by post-menopausal women for the relief of menopausal symptoms and the potential reduction of osteoporosis, HRT also increases their risk of Alzheimer's disease, stroke, breast cancer, and endometrial cancer. Since the majority of these effects are associated primarily with estrogen binding to only one of the estrogen receptors (ER), new assays are needed that can more efficiently evaluate ER-binding and identify ligands selective for ER-alpha and ER-beta. High performance liquid chromatography-tandem mass spectrometry (LC-MS-MS) was combined with ultrafiltration as a new method to investigate the relative binding of compounds to the ERs and to evaluate the structures of these estrogens. Mixtures of estradiol and six equine estrogens, including equilin, equilenin, 8,9-dehydroestrone, and their 17beta-hydroxyl derivatives, were assayed simultaneously to determine their relative binding to human ER-alpha and ER-beta. Estrogens containing a 17beta-OH group were found to have higher relative affinities for the estrogen receptors than their ketone analogs. In addition, 17beta-EN showed selectivity for binding to ER-beta over ER-alpha. The results were compared to the IC50 values obtained by using a conventional radiolabled estradiol competitive binding assay. Finally, the utility of negative ion electrospray tandem mass spectrometry for the unambiguous identification of these estrogen isomers was investigated. Several characteristic recyclization pathways during tandem mass spectrometry were identified, which might be useful for distinguishing related estrogens.
Unified L2 Abstractions for L3-Driven Fast Handover (2006)

This draft proposes unified L2 abstractions for fast
handovers. For efficient network communication, it is vital for a
protocol layer to know or utilize other layer's information such as
a form of L2 triggers. However, each protocol layer is basically
designed independently. Since each protocol layer is also implemented
independently in current operating systems, it is very hard to
exchange control information between protocol layers. To solve the
problem, this draft defines nine kinds of L2 abstractions in the form
of primitive to achieve fast in the network layer. This
mechanism is called L3-driven fast handovers because the network
layer initiates L2 and L3 by using the primitives.
Pulmonary Embolus after Vena Cava Filter Placement (1999)

This report characterizes risk factors in patients who suffer pulmonary embolus (PE) after insertion of vena caval filter (VCF) and formulates an organized diagnostic and therapeutic plan of management. Three hundred eighteen patients were included in a review of patients undergoing insertion of VCF from 1989 to 1995. Ten patients (six men and four women, ages 25-72 years) from this group (3.1%) experienced PE after VCF insertion. Risk factors for deep venous thrombosis were documented in these ten patients. Venacavography was performed after diagnosis of PE. Thrombus length measured from the apex of the filter was used to determine further therapy. Thrombus 5 cm or greater in length was treated with a second VCF (VCF-2). Smaller clots were treated with anticoagulation (AC). All patients treated with AC underwent repeat vena caval study (CT scan or venacavagram) 10 days to 18 months after treatment. PE occurred from 8 days to 5.5 years after original VCF insertion. Five patients suffered PE longer than 6 months (range, 21-66 months; mean, 39 months) after VCF insertion. Venacavagrams demonstrated thrombus in all ten patients with PE. Six patients were treated with VCF-2 and four patients with AC. Dissolution of thrombus was seen on follow-up in all patients given AC. All 10 patients harbored at least two risk factors for deep venous thrombosis. Malignancy was found in only two patients. Five patients were found to have procoagulant states characterized by decreased levels of anti-thrombin III or protein C or S. No postoperative deaths or early recurrent PE occurred. One patient experienced another PE 5 years after treatment with AC when she discontinued warfarin. Contraindications to AC appeared to be self-limited, and all patients were discharged on warfarin. No significant bleeding occurred during early follow-up. Our findings confirm the reliability and low complication rate for VCF. Patients experiencing PE after insertion of VCF mandate an aggressive diagnostic approach that should include venacavography and a search for identifiable risk factors including procoagulant state. Treatment with AC and insertion of a second VCF both give favorable results. All patients appear to benefit from short- or long-term warfarin therapy, and contraindications to AC frequently are self-limited. Therapy based on clot size warrants further study.
Apneustic breathing in children with brainstem damage due to hypoxic–ischemic encephalopathy (1999)

To confirm the presence of apneusis in patients with hypoxic-ischemic encephalopathy and to clarify which factors influence their respiratory patterns, polygraphic studies were performed on two patients. Apneusis was clinically suspected in both patients who had severe brainstem damage. In one subject, inputs of vagal afferents from the gastrointestinal tract and the urinary bladder often resulted in extreme tachypnea instead of apneusis. Lung inflation facilitated expiration during inspiratory arrest. Expiration preceded a periodic inhibition of rigospastic discharge in the right biceps muscle. In the other subject, prolonged inspiratory pauses with cyanosis occurred with or without preceding epileptic seizure. Both phenytoin dose reduction and treatment with tandospirone, a serotonin-1A agonist, were effective in improving the respiratory distress in this subject.
The Diffusion of Bismuth in Silicon (1989)

The diffusion of bismuth into silicon from a spin-on source has been investigated at a temperature range of 1050–1200°C. The concentration profile of bismuth agrees with the complementary error function, and its diffusion coefficient shows a value similar to the values of phosphorus and boron. Its activation energy is estimated to be 2.50 eV. That is much smaller than the values of phosphorus, boron and arsenic.
Power GaN HEMT degradation: from time-dependent breakdown to hot-electron effects (2018)

This paper describes our most advanced results in the field of GaN-HEMT degradation, with focus on power devices. We discuss three main aspects: (i) the first part of the paper analyzes the dependence of breakdown voltage on substrate and buffer properties, by reporting the results obtained on wafers with different substrate resistivities and superlattice thickness. (ii) the second part of the paper demonstrates the existence of time-dependent breakdown of GaN buffer submitted to high vertical stress, and describes the related process. (iii) in the third part of the paper, we focus on the role of hot-electrons in limiting the dynamic performance of the devices. We demonstrate that the exposure to hard switching transitions may lead to an increase in dynamic R <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">on</inf> . This effect is ascribed to the presence of hot electrons, which was verified by means of electroluminescence measurements.
Inhibition of Tomato Early Blight Disease by Culture Extracts of a <i>Streptomyces puniceus</i> Isolate from Mangrove Soil (2019)

This study investigates the potential of natural products derived from a mangrove rhizosphere bacterium in tomato early blight management. A <i>Streptomyces puniceus</i> strain L75 was isolated from the rhizosphere of <i>Acanthus ilicifolius</i> Linn in the Mai Po Reserve, Hong Kong. The crude ethyl acetate (EA) extract of L75 fermentation cultures has broad-spectrum antifungal bioactivities. L75 EA extract was significantly more effective in <i>Alternaria solani</i> growth inhibition at 25 μg/ml or lower compared with Mancozeb, with no observable negative impacts on tomato leaves or root development. Furthermore, L75 EA extract had significantly lower aquatic toxicity than Mancozeb at the same concentrations. L75 EA extract targets germ tube elongation of <i>A. solani</i> conidia, with a fungistatic mode of action. Liquid chromatography-quadrupole time-of-flight mass spectrometry analysis identified two possible antifungal compounds, Alteramide A and the Heat-Stable Antifungal Factor, which together contribute partially to the bioactivity of L75 EA extract. On detached tomato leaves, coinoculation of <i>A. solani</i> with L75 EA extract of 50, 25, or 5 μg/ml reduced diseased areas by ∼98, ∼90, and ∼48%, respectively, relative to the control after 5 days. This study demonstrates the potential of natural products from mangrove rhizosphere bacteria in agricultural applications.
