Simple homodyne technique for the characterisation of wideband optical detectors (1990)

In this work we present a simple self-homodyne technique for the characterisation of wideband photodetectors. This technique transforms the frequency modulation of the laser diode into intensity modulation using a 2-beam interferometer. When the laser diode is modulated by a triangular signal, the power is concentrated in one beating frequency component that can be swept by changing the amplitude of the modulating signal. The experimental and theoretical results are in good agreement. As an example, with the frequency of the modulating signal equals only 15 kHz we have measured a detector response of up to 1.5MHz.
Low-G Electrostatically Actuated Resonant Switch (2012)

This work investigates a new concept of an electrostatically actuated resonant switch (EARS) for earthquake detection and low-g seismic applications. The resonator is proposed to operate close to instability bands of frequency-response curves, where it is forced to pull-in if operated within these bands. By careful tuning, the resonator can be made to enter the instability zone upon the detection of the earthquake signal, thereby pulling-in as a switch. Such a switching action can be functionalized for alarming purposes or can be used to activate a network of sensors for seismic activity recording. The EARS is modeled and its dynamic response is simulated using a nonlinear single degree of freedom model. Experimental investigation is conducted demonstrating the EARS capability of being triggered at small levels of acceleration as low as 0.02 g. Experimental data and simulation results are compared showing good agreement.
Concerted Ring Opening and Cycloaddition of Chiral Epoxy Enolsilanes with Dienes (2015)

Abstract Silyl‐triflate‐catalyzed (4+3) cycloadditions of epoxy enolsilanes with dienes provide a mild and chemoselective synthetic route to seven‐membered carbocycles. Epoxy enolsilanes containing a terminal enolsilane and a single stereocenter undergo cycloaddition with almost complete conservation of enantiomeric purity, a finding that argues against the involvement of oxyallyl cation intermediates which have been previously proposed for these types of reactions. Reported are theoretical and experimental investigations of the cycloaddition mechanism. The major enantiomers of the cycloadducts are derived from S N 2‐like reactions of the silylated epoxide with the diene, in which stereospecific ring opening and formation of the two new CC bonds occur in a single step. Calculations predict, and experiments confirm, that the observed small losses of enantiomeric purity are traced to a triflate‐mediated double S N 2 cycloaddition pathway.
Hybrid type-I InAs/GaAs and type-II GaSb/GaAs quantum dot structure with enhanced photoluminescence (2015)

We investigate the photoluminescence (PL) properties of a hybrid type-I InAs/GaAs and type-II GaSb/GaAs quantum dot (QD) structure grown in a GaAs matrix by molecular beam epitaxy. This hybrid QD structure exhibits more intense PL with a broader spectral range, compared with control samples that contain only InAs or GaSb QDs. This enhanced PL performance is attributed to additional electron and hole injection from the type-I InAs QDs into the adjacent type-II GaSb QDs. We confirm this mechanism using time-resolved and power-dependent PL. These hybrid QD structures show potential for high efficiency QD solar cell applications.
Impact of γ-chain cytokines on EBV-specific T cell cultures (2010)

Our data indicated that the addition of γ-chain cytokines other than IL-2 for the generation of EBV-specific T cell cultures did not produce the improvements expected on the basis of recent published literature. This fact was likely due to the intrinsic differences between murine and human models and highlights the need to design ad hoc protocols rather than simply modify the cytokines added in culture.
Human-Centered Design for the Personal Satellite Assistant (2000)

The Personal Satellite Assistant (PSA) is a softball-sized flying robot designed to operate autonomously onboard manned spacecraft in pressurized micro-gravity environments. We describe how the Brahms multi-agent modeling and simulation environment in conjunction with a KAoS agent teamwork approach can be used to support human-centered design for the PSA.
A Review on RF ESD Protection Design (2005)

Radio frequency (RF) electrostatic discharge (ESD) protection design emerges as a new challenge to RF integrated circuits (IC) design, where the main problem is associated with the complex interactions between the ESD protection network and the core RFIC circuit being protected. This paper reviews recent development in RF ESD protection circuit design, including mis-triggering of RF ESD protection structures, ESD-induced parasitic effects on RFIC performance, RF ESD protection solutions, as well as characterization of RF ESD protection circuits.
[Fetal death in hydrops fetalis at 21 weeks of amenorrhea]. (1997)

L'observation Madame P.A., 32 ans, presente dans ses antecedents obstetricaux une premiere grossesse marquee par un diabete gestationnel. L'accouchement d'un enfant en bonne sante a eu lieu a terme en 1993. Une deuxieme grossesse debute en aout 1996. Madame P.A., immunisee contre la toxoplasmose et la rubeole, n'a pas d'antecedent d'allo-immunisation (absence d'anticorps irreguliers et test de Kleihauer apres la premiere grossesse negatif). Le debut de cette grossesse s'est deroule sans probleme particulier. Le depistage serique de trisomie 21, realise par dosage de l'hormone chorionique gonadotrope, couple a un dosage d'alpha-fœtoproteine, a mis en evidence l'existence d'un risque eleve et a conduit a la realisation, a 17 semaines et demie d'amenorrhee, d'une amniocentese pour caryotype fœtal qui s'est avere normal de type 46XX. Une echographie fœtale, realisee a 18 semaines et demie d'amenorrhee, permet de decouvrir un epanchement pericardique isole de faible abondance avec integrite des structures cardiaques. Les resultats de l'echographie motivent la demande chez la mere d'un serodiagnostic viral : le serodiagnostic de cytomegalovirus est negatif, le serodiagnostic de l'herpes simplex virus est positif en IgG et faiblement positif en IgM, et le serodiagnostic de parvovirus B19 est positif en IgG avec une reaction douteuse en IgM. Madame P.A. est revue en consultation d'echographie fœtale pour un deuxieme controle a 21 semaines d'amenorrhee. L'examen met en evidence une anasarque fœto-placentaire avec persistance de l'epanchement pericardique et apparition d'une ascite, une hepatomegalie importante et une cardiomegalie. Une ponction de sang fœtal permet de montrer un taux d'hemoglobine a 3 g/dl et une numeration plaquettaire a 89 000/mm3. Une exsanguino-transfusion in utero completee par une transfusion intra-peritoneale, realisee en urgence, permet d'augmenter le taux d'hemoglobine a 7 g/dl. La vitalite fœtale controlee dans la soiree est normale mais, malheureusement, le fœtus decede in utero le lendemain. Le diagnostic etiologique de cette anemie fœtale mortelle est confirme par la detection du genome viral du parvovirus B19 par amplification genique (PCR) de l'ADN dans le liquide amniotique et le liquide d'ascite ainsi que dans le placenta.

Grain yield, plant height, flour yield, flour protein, sedimentation volume, and other quality traits of the lines were similar to those of Biggar. Key words: Common root rot, resistance, Triticum aestivum, germplasm
The Innovations and Inventions of Steve Jobs [IP Corner] (2014)

Much of the world of patents is shrouded in layers of legal mysticism, semantic nuances, and subtle complexities. Those of you who are regular readers of "IP Corner" will know that I often try to explain the principles of the patenting process using real-world examples and case studies. I feel that this is probably the most useful approach to explain the many shades of gray of this world to engineers. Normally I focus on a particular aspect of patents and the patenting process and explore it through a series of examples. However, for this issue, I thought it might be interesting to take a different approach-why not explore a selection of the innovations of a well-known inventor to gain a different perspective and provide insight into the art and business of patenting your own inventions? And there is no better candidate for our first study than the man who founded and later rebuilt the most successful consumer electronics company of the 21st century-Steve Jobs.

Ergebnisse der zweiten Bundeswaldinventur: Holzvorrat, Holzzuwachs und Holznutzung (2005)

Der Holzvorrat in Deutschland ist so hoch wie nie zuvor. Mit 3,4 Mrd. cbm ist Deutschland das Land mit dem hochsten Gesamtholzvorrat in Europa, deutlich vor Schweden (2,9 Mrd. cbm), Frankreich (2,9 Mrd. cbm) und Finnland (1,9 Mrd. cbm). Um die gigantische Menge anschaulich zu machen, kann man sich einen bis zum Mond reichenden massiven Holzturm mit 3 x 3 m Grundflache vorstellen oder eine ganz Deutschland bedeckende massive Holzplatte von 1 cm Dicke.
Interactive Demonstration of Probabilistic Predicates (2018)

We will demonstrate a prototype query processing engine that uses probabilistic predicates (PPs) to speed up machine learning inference jobs. In current analytic engines, machine learning functions are modeled as user-defined functions (UDFs) which are both time and resource intensive. These UDFs prevent predicate pushdown; predicates that use the outputs of these UDFs cannot be pushed to before the UDFs. Hence, considerable time and resources are wasted in applying the UDFs on inputs that will be rejected by the subsequent predicate. We uses PPs that are lightweight classifiers applied directly on the raw input and filter data blobs that disagree with the query predicate. By reducing the input to be processed by the UDFs, PPs substantially improve query processing. We will show that PPs are broadly applicable by constructing PPs for many inference tasks including image recognition, document classification and video analyses. We will also demonstrate query optimization methods that extend PPs to complex query predicates and support different accuracy requirements.

Insulin secretion and action and the response of endogenous glucose production to a lack of glucagon suppression in nondiabetic subjects (2021)

In prediabetes, anthropometric characteristics as well as insulin action do not alter the hepatic response to glucagon. The postprandial suppression or lack of suppression of glucagon secretion is an important factor governing postprandial glucose tolerance independent of insulin secretion.
Frequency conversion through time refraction using an epsilon-near-zero material (2019)

We report a large and tunable frequency shifting over 14.8 THz bandwidth of an infrared probe beam through time refraction in indium tin oxide (ITO) in its epsilon-near-zero region. The sign of the frequency change can be controlled by adjusting the delay between a pump and the probe.
Dopamine D1Receptors and Nonlinear Probability Weighting in Risky Choice (2010)

Misestimating risk could lead to disadvantaged choices such as initiation of drug use (or gambling) and transition to regular drug use (or gambling). Although the normative theory in decision-making under risks assumes that people typically take the probability-weighted expectation over possible utilities, experimental studies of choices among risks suggest that outcome probabilities are transformed nonlinearly into subjective decision weights by a nonlinear weighting function that overweights low probabilities and underweights high probabilities. Recent studies have revealed the neurocognitive mechanism of decision-making under risk. However, the role of modulatory neurotransmission in this process remains unclear. Using positron emission tomography, we directly investigated whether dopamine D₁ and D₂ receptors in the brain are associated with transformation of probabilities into decision weights in healthy volunteers. The binding of striatal D₁ receptors is negatively correlated with the degree of nonlinearity of weighting function. Individuals with lower striatal D₁ receptor density showed more pronounced overestimation of low probabilities and underestimation of high probabilities. This finding should contribute to a better understanding of the molecular mechanism of risky choice, and extreme or impaired decision-making observed in drug and gambling addiction.
Remplissage Versus Modified Latarjet For Off-Track Hill-Sachs Lesions With Subcritical Glenoid Bone Loss (2017)

Objectives: Off track Hill-Sachs lesions have been associated with high rate of recurrent shoulder instability. Both arthroscopic Bankart with Remplissage and modified Latarjet have been described to treat off-track Hill-Sachs lesions. However, few comparative studies exist between the two techniques in heterogeneous populations. The purpose of this study was to examine the outcome of the two procedures in patients with off-track Hill-Sachs lesions with subcritical (&lt;25%) glenoid bone loss, both in the primary and revision setting. Methods: Arthroscopic Bankart with Remplissage was performed in thirty-one patients and modified Latarjet was performed in forty patients with recurrent anterior shoulder instability, off-track Hill-Sachs lesion, and less than 25% glenoid bone loss. Surgeries were performed at two centers. Patients were divided based on if they have had no previous surgical stabilization (Group A) or if they have had one or more previous surgical stabilization (Group B). The mean follow up time was four years. Patients were assessed for their risk of recurrence using the Instability Severity Index score and had preoperative 3-dimensional imaging to assess humeral and glenoid bone loss. Single Assessment Numeric Evaluation (SANE), Western Ontario Shoulder Instability Index (WOSI), radiographs, range of motion, recurrence rate, subsequent procedures and complications were analyzed. Results: In the thirty-two patients of group A, seventeen had remplissage and fifteen had Latarjet performed. Within group A, there were no difference found between the two techniques in regards to SANE, WOSI, range of motion (p&gt;0.35). There were no complications, recurrence or revision with both techniques in group A. In the thirty-nine patients of group B, fourteen had remplissage and twenty-five had Latarjet performed. In group B, the reoperation surgery rate was significantly higher in the remplissage group (36% vs 8%, p=0.044). The reoperation was performed predominately for pain in patients with remplissage and for recurrent instability with Latarjet. Recurrence instability rate were similar between the remplissage and Latarjet group (14% vs 8%, p=0.45). The WOSI score was similar between the remplissage and Latarjet group (405 vs 461, p=0.66). The complication rate was also similar (36% vs 40%, p=1). Conclusion: For off-track Hill-Sachs lesions with subcritical glenoid bone loss, both the remplissage and modified Latarjet can achieve excellent clinical results in the primary setting (no previous instability surgery). However, in the revision setting (one or more previous instability surgery), patients with remplissage may have a higher reoperation rate.

Resistance Evaluation and Growth of Carbon Nanotubes (2006)

We have investigated electronic transport in single-wall carbon nanotubes attached to multiple electrodes. Resistance measurement using a pair of electrodes with different gaps enabled separate evaluation of nanotube resistivity and contact resistance. We found that the resistivity depends on nanotube diameter. Electrodes with gold or palladium exhibit similar contact resistance with an order of 10kΩ. Contact resistance is insensitive to back gate voltage, contrary to the Schottky-barrier transistor model. We also demonstrated the top-down control of diameter and position of Fe catalysts by means of “lithographically anchored nanoparticle synthesis (LANS)” for nanotube growth. Chemical vapor deposition by using these patterned particles successfully produced single-wall carbon nanotubes.
RESERVOIR PROPERTIES OF BARREMIAN–APTIAN URGONIAN LIMESTONES, SE FRANCE, PART 2: INFLUENCE OF DIAGENESIS AND FRACTURING (2020)

Integrated sedimentological, diagenetic and structural analyses have been carried out on microporous and tight Urgonian (Barremian – Aptian) limestones in a study area in SE France in order to understand the influence of diagenetic changes and structural deformation on the spatial distribution of reservoir properties. A diagenetic history for the carbonates was established and was divided into phases which correspond to episodes of regional geodynamic activity. Petrographic (optical, SEM and cathodoluminescence microscopy), structural and geochemical (δ 18 O, δ 13 C) studies were carried out to characterize the cement phases in the carbonates, especially micrite and blocky calcite, and to investigate their relationship with episodes of fracturing. Eleven calcite cement phases and four micritic cement phases were identified in relation to the two main phases of structural deformation which affected the Urgonian limestones. A first phase of micrite cementation occurred early in the diagenetic history and was linked to early marine cementation at the tops and bases of depositional cycles during the Barremian. A major phase of micrite recrystallization, which generated microporosity in carbonates that had previously been preserved from early cementation, was followed by a first phase of blocky calcite which occluded intergranular pore spaces. The blocky cement formed in a shallow burial meteoric environment and contributed to the preservation of microporosity during late Durancian tectonism (Albian – Cenomanian). A second phase of blocky calcite is associated with fracture activation during latest Eocene (Priabonian) – Oligo‐Miocene extension. Reservoir rock‐types (RRTs) proposed in a previous study were consistent with the diagenetic characteristics and the results of δ 13 C / δ 18 O analyses. Microporous RRTs formed as a result of early to late shallow burial processes and display low δ 13 C values; whereas cemented RRTs developed both due to early marine cementation (with high δ 13 C values) and/or as a result of cementation related to fluid flow linked to the reactivation of faults and fractures. This suggests that some late diagenetic and microstructural processes were pre‐determined by early diagenetic changes in the carbonates. The resulting stratigraphic architecture consists of a vertical stacking of weakly fractured microporous limestone intervals alternating with highly fractured, cemented limestone units.
Subsystem and System-level Implications of PCM (2011)

Robert Haas, Xiao-Yu Hu, Ioannis Koltsidas, Roman A. Pletka IBM Research – Zurich, 8803 Ruschlikon, Switzerland, {rha,xhu,iko,rap}@zurich.ibm.com ABSTRACT Emerging data-centric workloads necessitate systems with highly scalable storage components, not only in terms of capacity, but also in terms of performance and energy efficiency. These requirements, in combination with advances in Storage Class Memory (SCM) technologies, will drive the departure from traditional memory and storage architectures. The focus of this paper is on systems that employ Phase-Change Memory (PCM) to either complement or replace traditional media such, as HDDs, protected DRAM, and Flash. We study possible uses of PCM across the entire stack, and present an analysis of the implications this has for the various components, such as the main memory subsystem, storage subsystems, operating systems, filesystems and databases, as well as of its impact on the overall system architectures. Key problems introduced by the new medium are identified and solutions are outlined, which, we believe, will be very valuable for the designers of next-generation data-centric systems and applications.
