A differential SiP (LNA-filter-mixer) in silicon technology for the SKA project (2007)

This paper describes two filters realised in a technology entirely dedicated to passive components and which allows active dies flip-chip by means of bumps. Then, it presents the design of a SiP (system in package) constituted of a differential LNA (low noise amplifier) and mixer flipped respectively in front and back of a balanced filter. Measurements of a SiP, where just the LNA is flipped onto the filter, are shown in the last part.
Hydrocarbon Oxidation with H2O2, Catalyzed by Iron Complexes with a Polydentate Pyridine-Based Ligand (2010)

We report the structural and functional features of two new catalysts: a mononuclear [Fe(N5mpy)(CH3CN)](BF4)2 (N5mpy = (N,N′E,N,N′E)-N,N′-(pyridine-2,6-diylbis(ethan-1-yl-1-ylidene))bis(1-(pyridin-2-yl)methanamine)) complex and a binuclear {[Fe(N5mpy)]2O}(BF4)4 complex. Both compounds catalyze the oxidation of alkanes by H2O2, in MeCN or acetone to yield alcohols and ketones. Moderate to good yields are obtained with various cyclic and benzylic alkanes. Screening of several substrates revealed that higher yields are obtained for the oxidation of alkanes with low C–H bond dissociation energies. The ratio alcohol/ketone observed suggests the involvement of iron-based oxidizing species.
Effect of weak and ultraweak combined magnetic fields and low-intensity microwaves on regeneration in the planarian Dugesia tigrina (2007)

Regeneration (blastema growth) in Dugesia tigrina was accelerated if prior to transection the planarians were exposed to a weak constant magnetic field (42 μT) combined with an ultraweak alternating magnetic field (40 nT, 3.7 Hz); lesser stimulation was obtained with weak microwaves (100 μW/cm2 at 36 GHz). Field exposure after transection produced only half of the effect (magnetic field) or none at all (microwaves).
Accumulation of Lead and Arsenic by Potato Grown on Lead–Arsenate-Contaminated Orchard Soils (2016)

There are concerns of potential food chain transfer of metals in crops grown on lead–arsenate-contaminated soils. The objective of this study was to investigate lead and arsenic uptake by four potato (Solanum tuberosum L.) cultivars grown on lead–arsenate-contaminated soils with lead and arsenic concentrations ranging from 350 to 961 and 43 to 290 mg kg−1, respectively. Yield was not reduced due to treatment. Potato tubers were washed thoroughly before peeling. Lead concentration in both peeled tubers and peel was below instrument detection limit. Arsenic concentration in peeled tubers grown on the lead–arsenate soils ranged from 0.24 to 1.44 mg kg−1. Arsenic concentration was 60% higher in the peel than in the peeled tuber. The relatively high arsenic levels in the peel demonstrated that arsenic was taken up into the potato peel tissue. It is recommended that if potatoes are grown on these soils they should be peeled before consumption.Abbreviations Pb, lead; As, arsenic; DW, dry weight; FW, fresh weight
A Study on Subject Matter Expertise (2012)

 A Study on Subject Matter Expertise Inbal Tadeski, Omer Barkol, Ruth Bergman HP Laboratories HPL-2012-239 expertise retrieval; graph mining; collaboration systems We suggest a method to automatically evaluate employees' subject matter expertise in knowledge management systems. The approach stems from several conclusions that arose in extensive research of subject matter experts and their expertise. We find that self-reported expertise is biased and constantly changing. We, furthermore, observe that automatic methods to infer expertise perform about as well as self-reported profiles. The crux of the proposed method is to combine automatic inference expertise with the benefit of the expert's opinion, and to do so periodically so the profile remains accurate and fresh.

IGFBP-5 Metabolism Is Disrupted in the Rat Medial Meniscal Tear Model of Osteoarthritis (2010)

Insulin-like growth factor binding protein 5 (IGFBP-5) has been proposed to promote cartilage anabolism through insulin-like growth factor (IGF-1) signaling. A proteolytic activity towards IGFBP-5 has been detected in synovial fluids from human osteoarthritic (OA) joints. The purpose of this study was to determine if protease activity towards IGFBP-5 is present in the rat medial meniscal tear (MMT) model of OA and whether inhibition of this activity would alter disease progression. Sprague-Dawley rats were subject to MMT surgery. Synovial fluid lavages were assessed for the presence of IGFBP-5 proteolytic activity. Treatment animals received intra-articular injections of vehicle or protease inhibitor peptide PB-145. Cartilage lesions were monitored by India ink staining followed by macroscopic measurement of lesion width and depth. The MMT surgery induced a proteolytic activity towards IGFPB-5 that was detectable in joint fluid. This activity was stimulated by calcium and was sensitive to serine protease inhibitors as well as peptide PB-145. Significantly, intra-articular administration of PB-145 after surgery protected cartilage from lesion development. PB-145 treatment also resulted in an increase in cartilage turnover as evidenced by increases in serum levels of procollagen type II C-propeptide (CPII) as well as synovial fluid lavage levels of collagen type II neoepitope (TIINE). IGFBP-5 metabolism is disrupted in the rat MMT model of OA, potentially contributing to cartilage degradation. Inhibition of IGFBP-5 proteolysis protected cartilage from lesion development and enhanced cartilage turnover. These data are consistent with IGFBP-5 playing a positive role in anabolic IGF signaling in cartilage.
High-Efficiency Zn-Diffused GaAs Electroluminescent Diodes (1972)

Electroluminescent GaAs diodes have been fabricated in heavily doped (n &gt; 1018 cm−3) GaAs using ZnAs2 or a Zn–Ga solution as a diffusion source. Using the Zn–Ga source, efficiencies of 1.3–1.4% for planar uncoated devices and 3.2–3.5% with an Epoxy lens are reproducibly obtained, and uncoated devices with efficiencies as high as 1.7% have been observed. A variety of GaAs crystals were evaluated in order to determine the type most suitable for the fabrication of diffused electroluminescent diodes. The optimum material was found to be Si-doped GaAs with n in the range (2–3) × 1018 cm−3. Both Czochralski and boat-grown GaAs were investigated. The device efficiency has been found to depend strongly on the etch-pit density of the crystal, with maximum efficiencies obtained for boat-grown GaAs with Δ &lt; 103 cm−2. A series of zero dislocation crystals grown using the Czochralski technique was investigated and found to yield lower efficiency devices than boat-grown GaAs with an etch-pit density between 102 and 103 cm−2.
Modulator Effect of Acetic Acid on the Morphology of Luminescent Mixed Lanthanide-Organic Frameworks (2017)

The control of the size and morphology of Metal-Organic Frameworks is a challenge that must be overcome to ensure the use of these materials in advanced applications. Mixed Lanthanide-Organic Frameworks (MLOFs) were synthesized via solvo(hydro)thermal method and then characterized by PXRD, IR, TG/DTA, SEM and PL spectroscopy. The effect of the modulator (acetic acid) on the morphological characteristics of the obtained powders was investigated. Trivalent terbium ions were successfully incorporated into La-framework conferring green luminescence to the prepared samples. It was observed that a gradual increase in acetic acid concentration led to the morphology change from micro-rods to flower-like small particle agglomerates. Moreover, a higher concentration of the acetic acid prevented the crystallization of secondary phases.
Cognitive Small Cell Networks: Energy Efficiency and Trade-Offs (2013)

Heterogeneous networks using a mix of macrocells and small cells are foreseen as one of the solutions to meet the ever increasing mobile traffic demand. Nevertheless, a massive deployment of small cell access points (SAPs) leads also to a considerable increase in energy consumption. Spurred by growing environmental awareness and the high price of energy, it is crucial to design energy efficient wireless systems for both macrocells and small cells. In this work, we evaluate a distributed sleep-mode strategy for cognitive SAPs and we analyze the trade-off between traffic offloading from the macrocell and the energy consumption of the small cells. Using tools from stochastic geometry, we define the user discovery performance of the SAP and derive the uplink capacity of the small cells located in the Voronoi cell of a macrocell base station, accounting for the uncertainties associated with random position, density, user activity, propagation channel, network interference generated by uncoordinated activity, and the sensing scheme. In addition, we define a fundamental limit on the interference density that allows robust detection and we elucidate the relation between energy efficiency and sensing time using large deviations theory. Through the formulation of several optimization problems, we propose a framework that yields design guidelines for energy efficient small cell networks.
Eigenface-domain super-resolution for face recognition (2003)

Face images that are captured by surveillance cameras usually have a very low resolution, which significantly limits the performance of face recognition systems. In the past, super-resolution techniques have been proposed to increase the resolution by combining information from multiple images. These techniques use super-resolution as a preprocessing step to obtain a high-resolution image that is later passed to a face recognition system. Considering that most state-of-the-art face recognition systems use an initial dimensionality reduction method, we propose to transfer the super-resolution reconstruction from pixel domain to a lower dimensional face space. Such an approach has the advantage of a significant decrease in the computational complexity of the super-resolution reconstruction. The reconstruction algorithm no longer tries to obtain a visually improved high-quality image, but instead constructs the information required by the recognition system directly in the low dimensional domain without any unnecessary overhead. In addition, we show that face-space super-resolution is more robust to registration errors and noise than pixel-domain super-resolution because of the addition of model-based constraints.
Thyroid hormone promotes the phosphorylation of STAT3 and potentiates the action of epidermal growth factor in cultured cells (1999)

We have examined the effects of l-thyroxine (T4) on the activation of signal transducer and activator of transcription 3 (STAT3) and on the STAT3-dependent induction of c-Fos expression by epidermal growth factor (EGF). T4, at a physiological concentration of 100 nM, caused tyrosine phosphorylation and nuclear translocation (i.e. activation) of STAT3 in HeLa cells in as little as 10–20 min. Activation by T4 of STAT3 was maximal at 30 min (15±4-fold enhancement; mean±S.E.M.) in 18 experiments. This effect was reproduced by T4–agarose (100 nM) and blocked by CGP 41251, genistein, PD 98059 and geldanamycin, inhibitors of protein kinase C (PKC), protein tyrosine kinase (PTK), mitogen-activated protein kinase (MAPK) kinase and Raf-1 respectively. Tyrosine-phosphorylated MAPK also appeared in nuclear fractions within 10 min of treatment with T4. In the nuclear fraction of T4-treated cells, MAPK immunoprecipitate also contained STAT3. The actions of T4 were similar in HeLa and CV-1 cells, which lack thyroid hormone receptor (TR), and in TR-replete skin fibroblasts (BG-9). T4 also potentiated the EGF-induced nuclear translocation of activated STAT1α and STAT3 and enhanced the EGF-stimulated expression of c-Fos. Hormone potentiation of EGF-induced signal transduction and c-Fos expression was inhibited by CGP 41251, geldanamycin and PD 98059. Therefore the non-genomically induced activation by T4 of STAT3, and the potentiation of EGF by T4, require activities of PKC, PTK and an intact MAPK pathway.
Inhibition of arabinose 5-phosphate isomerase. An approach to the inhibition of bacterial lipopolysaccharide biosynthesis (1984)

Arabinose 5-phosphate ( A5P ) isomerase is a key enzyme in the biosynthesis of lipopolysaccharide, an essential component of the outer membrane of Gram-negative bacteria. The mechanism of the isomerase is envisioned to involve an enediol intermediate. A series of compounds, which are analogues of the substrates or intermediate, were tested as inhibitors of A5P isomerase with the belief that a good inhibitor would stop bacterial growth or render the cells more susceptible to other antibiotics or natural defenses. In a series of phosphorylated sugars, the order of isomerase inhibitory activity was as follows: aldonic acids greater than alditols greater than aldoses. Nonphosphorylated sugars were much less inhibitory. The best inhibitor was erythronic acid 4-phosphate (54), which had Km/Ki = 29. None of the compounds displayed antibacterial activity in vitro.
THE RESPONSE OF INBRED MICE TO OESTROGENS (1955)

SUMMARY The vaginal response of two inbred lines of mice (C 57 and CBA), and their reciprocal crosses, to oestrone and oestradiol-3:17β has been studied, with the subcutaneous and intravaginal routes of administration. In all cases the variability of the response of F 1 hybrids was approximately 25% of the variability of the inbred lines. In the intravaginal tests the median effective dose ( m.e.d. ) was the same for both inbred lines, while the m.e.d. for the F 1 hybrids was less. In the subcutaneous tests the C 57 line has a lower m.e.d. than the CBA line, while the m.e.d. of the F 1 hybrids was lower than both the inbred lines. This phenomenon is an example of heterosis, and the findings have been discussed in relation to bioassay and experimental study of oestrogens, and to mammary carcinoma in the mouse.
State-Variable Representations For Moving-Average Sampling (1991)

Two state-variable representations derived for continuous-time plant driven by control algorithm including zero-order hold and measurements sampled at mutliple rates by multiple-input/multiple-output moving-average processes. New representations enhance observability and controllability of plant. Applications include mathematical modeling of navigation systems including star trackers, gyroscopes, and accelerometers.
On the efficiency of some suboptimal algorithms for bit decoding of binary codes (2002)

Several popular, suboptimal algorithms for bit decoding of binary block codes such as turbo decoding, threshold decoding, and message passing for LDPC, were developed almost as a common sense approach to decoding of some specially designed codes. We explain exactly how they approximate the optimal decoding algorithm, and show how good this approximation is in some special cases.
Process Development of (1<i>S</i>,2<i>S</i>,5<i>R</i>,6<i>S</i>)- Spiro[bicyclo[3.1.0]hexane-2‘,5‘-dioxo-2,4‘-imidazolidine]-6-carboxylic Acid, (<i>R</i>)-α-Methylbenzenemethanamine Salt (LSN344309) (2005)

Process development and a pilot-plant process for the synthesis of 4 and its resolution to obtain (1S,2S,5R,6S)-spiro[bicyclo[3.1.0]hexane-2‘,5‘-dioxo-2,4‘-imidazolidine]-6-carboxylic acid, (R)-α-methylbenzenemethanamine salt (5) are described. Starting from the inexpensive raw 2-cyclopenten-1-one and sulfur ylide 1 the racemic bicyclo keto ester 2 was synthesized. Reaction of 2 with potassium cyanide and ammonium carbonate under Bücherer−Berg's reaction conditions affords racemic 3 in 80% yield. Hydrolysis of 3 followed by the resolution with (R)-(+)-α-methylbenzylamine gave 4 in excellent yield and purity under optimized conditions. The improvement of the original discovery process to accommodate safety and environmental requirements for scale-up in manufacturing facilities is also discussed.
Chain growth in the base catalyzed hydrogen transfer polymerization of acrylamide to poly(β‐alanine) (1970)

Abstract Yields and reduced specific viscosities of the products of the sodium tert ‐butoxide catalyzed hydrogen transfer polymerization at 100°C of acrylamide in 1‐methyl‐2‐pyrrolidone have been determined as a function of time of polymerization. The results conclusively prove a stepwise chain growth mechanism since the early stages of the reaction.

Efectos secundarios de la azardiractina, vía contacto residual, en larvas jóvenes del depredador Chrysoperla carnea (Stephens) (Neuroptera, Chrysopidae) (1998)

New Pr1-xZrxO2-y oxides with x < 0.5 have been prepared by co-precipitation in basic medium and annealed under air at high temperatures (T≤ 1200 °C). Defined compositions with x = 0.02, 0.1, 0.2, 0.35, 0.40 and 0.5 have been characterized by XRD, Zr-K-edge EXAFS for the local structure, magnetic susceptibility measurements, and Pr LIII-edge XANES in order to identify the variation of the cell parameter and Zr local environment versus Zr content and Pr(n+) (4 < n < 3) oxidation states. The higher the Zr content, the lower the Pr valence state. The Zr amount stabilized in the distorted octahedral site is at the origin of the formation of defined compositions as discovered by Leroy Eyring et al. in the PrnO2n-2m series and the generation of oxygen vacancies stabilized in the fluorite-type network. TGA and TPR analyses help to follow the reduction properties under Ar/5% H2 and show high Pr reducible rates at low temperatures (T < 250 °C). The identification of the fluorite-type superstructure (SG: Ia3[combining macron]) of reduced compositions annealed at T = 900 °C under Ar/5% H2 shows the cationic and oxygen vacancy ordering. This feature plays a key role with Zr(4+) cations stabilized in flattened octahedral sites for the generation of oxygen vacancies and the stabilization of Pr(3+) in the reduced states.
New perspectives in multi-nucleon pion absorption on light nuclei (1997)

Multinucleon absorption cross sections have been measured in 3He and 4He with three unbound, energetic nucleons in the final state. The ratios of the different 3NA cross sections are difficult to understand in terms of only two-step processes. Similar difficulties appear in the decomposition of the 3NA yield into mechanisms. Although a part of this yield is identified to be due to two-step processes, a large fraction is well described by a simple phase space model. (AIP)
Olfactory neurons exhibit heterogeneity in depolarization-induced calcium changes (1990)

Olfactory neurons from the channel catfish, Ictalurus punctatus, were isolated by a brief (15 min) treatment with papain. After incubation with fura-2 acetoxymethyl ester (fura-2/AM) for 1 h, the isolated olfactory receptor cells are found to hydrolyze fura-2/AM to fura-2 free acid without detectable traces of intermediate products of hydrolysis. Intracellular calcium measured with fura-2 in single cells covers a wide range (from less than 2 to 100 nM with a median of 17.6 nM, n = 140 cells). Twenty-one percent of the cells respond to potassium-induced depolarization with an increase in intracellular calcium mediated by influx of extracellular calcium. The L-type calcium channel antagonist nimodipine inhibits the increase in intracellular calcium triggered by membrane depolarization and blocks small unitary barium currents displaying the characteristics of L-type calcium currents (unitary conductance of 29 +/- 5 pS in 55 mM BaCl2 and high selectivity for Ba2+ over Na+ and K+) recorded from azolectin bilayers at the tip of patch pipettes into which isolated olfactory cilia membrane vesicles had been incorporated. Olfactory neurons are found to be functionally heterogeneous in their response to membrane depolarization and can be separated into three groups: one in which the increase in intracellular calcium is rapid and transient, another in which calcium increases slowly, and a third group of cells in which depolarization causes no change in intracellular calcium.
Unexpected Isomerism in <i>cis</i>‐2 Bis(pyrrolidino)[60]Fullerene Diastereomers (2013)

Similar yet different: A one-step regio- and diastereoselective synthesis of three new bis(pyrrolidine)[60]fullerenes, one cis-1 and two unprecedented cis-2 diastereoisomers, is reported. The compounds are easily purified using simple chromatographic techniques, and were fully characterized by spectroscopic techniques and X-ray crystallography. A mechanism for the isomeric conversion observed is proposed.
Walking Pattern Filter for Dynamic Biped Robot With SMA Actuators (2006)

In this paper we present a walking pattern filter for Shape Memory Alloy (SMA) actuated biped robots. SMAs are known for their slow response. The actuation speed limitation can potentially lead to stability problems for biped robots. This filter adapts the human motion for a SMA biped in order to have a stable walking pattern. The Zero Moment Point (ZMP) is used as a main criterion of the filter to guarantee the stability of the motion. The SMA actuators are designed based on the dynamic and kinematics data of the motion. The response time of each SMA actuator is modeled in order to estimate the behavior of the actuator in realizing the given trajectory. After applying the delay times to the motion new trajectories are generated and checked by the ZMP criterion. The output of the filter can generate smooth trajectories for the SMA biped robots. The filter furthermore guarantees the stability while mimicking the human motion. The filter provides a practical way to create stable walking patterns using SMA actuators.
