Industrial integration of high coherence tunable single frequency semiconductor lasers based on VECSEL technology for scientific instrumentation in NIR and MIR (2017)

Laser technology is finding applications in areas such as high resolution spectroscopy, radar-lidar, velocimetry, or atomic clock where highly coherent tunable high power light sources are required. The Vertical External Cavity Surface Emitting Laser (VECSEL) technology [1] has been identified for years as a good candidate to reach high power, high coherence and broad tunability while covering a wide emission wavelength range exploiting III-V semiconductor technologies. Offering such performances in the Near- and Middle-IR range, GaAs- and Sb-based VECSEL technologies seem to be a well suited path to meet the required specifications of demanding applications. Built up in this field, our expertise allows the realization of compact and low power consumption marketable products, with performances that do not exist on the market today in the 0.8-1.1 &mu;m and 2-2.5 &mu;m spectral range. Here we demonstrate highly coherent broadly tunable single frequency laser micro-chip, intracavity element free, based on a patented VECSEL technology, integrated into a compact module with driving electronics. VECSEL devices emitting in the Near and Middle-IR developed in the frame of this work [2] exhibit exciting features compared to diode-pumped solid-state lasers and DFB diode lasers; they combine high power (&gt;100mW) high temporal coherence together with a low divergence diffraction limited TEM00 beam. They exhibit a class-A dynamics with a Relative Intensity Noise as low as -140dB/Hz and at shot noise level reached above 200MHz RF frequency (up to 160GHz), a free running narrow linewidth at sub MHz level (fundamental limit at Hz level) with high spectral purity (SMSR &gt;55dB), a linear polarization (&gt;50dB suppression ratio), and broadband continuous tunability greater than 400GHz (&lt; 30V piezo voltage, 6kHz cut off frequency) with total tunability up to 3THz. Those performances can all be reached thanks to the high finesse cavity of VECSEL technology, associated to ideal homogeneous QW gain behaviour [3]. In addition, the compact design without any movable intracavity elements offers a robust single frequency regime with a long term wavelength stability better than few GHz/h (ambient thermal drift limited). Those devices surpass the state of the art commercial technologies thanks to a combination of power-coherence-wavelength tunability performances and integration.
Generating irregular data-stream accelerators : methodology and applications (2015)

This thesis presents Gorilla++, a language and a compiler for generating customized hardware accelerators that process input streams of data.Gorilla++ uses a hierarchical programming model with sequential engines run in parallel and communicate through FIFO interfaces.It also incorporates offload and lock constructs in the language to support safe accesses to global resources.Beside conventional compiler optimizations for regular streaming, the programming model opens up new optimization opportunities including (i) multi-threading to share computation resources by different execution contexts inside an engine, (ii) offload-sharing to share resources between different engines, and (iii) pipe-offloading to pipeline part of a computation that is not efficiently pipelinable as a whole.Due to the dynamic nature of Gorilla++ target applications, closedform formulations are not sufficient for exploring the design space of accelerators.Instead, the design space is explored iteratively using a rule-based refinement process.In each iteration, the rules capture inefficiencies in the design, either bottlenecks or under-utilized resources, and change the design to eliminate the inefficiencies.vii Gorilla++ is evaluated by generating a set of FPGA-based networking and big-data accelerators.The experimental results demonstrate (i) the expressiveness and generality of Gorilla++ language, (ii) the effectiveness of Gorilla++ compiler optimizations, and (iii) the improvement in the design space exploration (DSE) using rule-based refinement process.
Opportunities and challenges in ultra low k dielectrics for interconnect applications (2002)

Reactivating a Tight Carbonate Reservoir in the Greater Burgan Field: Challenges, Options and Solutions (2013)

Abstract The Mauddud Formation in the Greater Burgan field is a thin carbonate reservoir with very low permeability but with moderate to good porosity and variable fracture density. The formation could be divided into three distinctive layers, based on the structural and digenetic complexities. Production in Mauddud wells show rapid decline due to tight rock matrix (low permeability). This decline is associated with an increase in Gas-Oil Ratio (GOR) as reservoir pressure falls below the bubble point pressure near the wellbore. Horizontal wells were drilled in an attempt to develop the Mauddud Formation targeting sweet zone. Most of the wells were located in a relative structural high on the up-thrown blocks of the North and Eastern flank of the Greater Burgan field that had the highest likelihood of intersecting fractures. They are mostly adjoining the major faults. There are now around 40 wells drilled in Mauddud including horizontal and multilaterals, most of which became non-producers due to above reasons. A study has been carried out to evaluate opportunities to revive these wells through available and new technologies in the industry. A detailed geological study incorporating all the available data was carried out initially. Wells were screened for stimulation by using various proven new technologies. Acid Frac, Stage Frac, near well bore SurgiFrac and Matrix Acid techniques have been applied with varying results. Advanced placement technique like distributed temperature profiling was used in some of the jobs. This paper presents the details of the application of the above mentioned technologies, to the candidate wells and discusses the results. The success of some of these technologies opened up new opportunities for a new beginning to revive the closed wells completed in Mauddud Formation.
A Quantitative Signaling Screen Identifies CARD11 Mutations in the CARD and LATCH Domains That Induce Bcl10 Ubiquitination and Human Lymphoma Cell Survival (2012)

Antigen receptor signaling to NF-κB, essential for normal lymphocyte activation, is dysregulated in several types of lymphoma. During normal signaling, the multidomain adapter CARD11 transitions from a closed, inactive state to an open, active scaffold that assembles a multiprotein complex, leading to NF-κB activation. The regulation of CARD11 scaffold function is bypassed by lymphoma-associated oncogenic CARD11 mutations that induce spontaneous signaling. We report an unbiased high-throughput quantitative signaling screen that identifies new CARD11 hyperactive variants and defines a LATCH domain that functions with the CARD to promote CARD11 autoinhibition. Gain-of-function mutations in the LATCH or CARD disrupt inhibitory domain binding, promote Bcl10 association, and induce Bcl10 ubiquitination, NF-κB activation, and human lymphoma cell survival. Our results identify CARD11 mutations with oncogenic potential, provide a mechanistic explanation for their signaling potency, and offer a straightforward method for the discovery of variants that promote the tumorigenesis of NF-κB-dependent lymphomas.
Protective Role of DNJ-27/ERdj5 in Caenorhabditis elegans Models of Human Neurodegenerative Diseases (2013)

Our data support a scenario where the levels of DNJ-27/ERdj5 in the ER impact cytoplasmic protein homeostasis and the integrity of the mitochondrial network which might underlie its protective effects in models of proteotoxicity associated to human ND.
Selectively oxidized vertical-cavity lasers (2002)

Summary form only given. During 1995 there has been rapid advance in the performance of vertical-cavity surface emitting lasers (VCSELs) fabricated using the conversion of AlGaAs into a stable oxide. VCSELs with Al-oxide current apertures have exhibited the highest wall plug efficiency and lowest threshold current reported to date for VCSELs. We discuss the fabrication and performance of IR and visible VCSELs employing buried oxide layers within monolithic distributed Bragg reflectors for efficient electrical and optical confinement.
Estimation of protein fractional synthetic rate from tracer data (1993)

The fractional synthetic rate (FSR) is a key parameter characterizing protein turnover that is estimated from tracer kinetic data. Formulas to estimate this parameter usually assume a precursor-product model. Assuming this model is correct, we discuss these formulas to estimate the FSR in the steady and non-steady state both for the radioactive and stable isotope tracer. Then we deal with the non-steady-state case where the FSR becomes time varying and derive formulas for its estimation. A non-steady-state case study on the flooding-dose technique for measuring protein turnover is presented.
Quantum Dynamics of Attractive and Repulsive Polarons in a Doped MoSe$_2$ Monolayer (2023)

When mobile impurities are introduced and coupled to a Fermi sea, new quasiparticles known as Fermi polarons are formed. There are two interesting, yet drastically different regimes of the Fermi polaron problem: (I) the attractive polaron (AP) branch, connected to pairing phenomena spanning the crossover from BCS superfluidity to the Bose-Einstein condensation of molecules; and (II) the repulsive branch (RP), which underlies the physics responsible for Stoner's itinerant ferromagnetism. Here, we study Fermi polarons in two dimensional systems, where many questions and debates regarding their nature persist. The model system we investigate is a doped MoSe$_2$ monolayer. We find the observed AP-RP energy splitting and the quantum dynamics of attractive polarons agree with the predictions of polaron theory. As the doping density increases, the quantum dephasing of the attractive polarons remains constant, indicative of stable quasiparticles, while the repulsive polaron dephasing rate increases nearly quadratically. The dynamics of Fermi polarons are of critical importance for understanding the pairing and magnetic instabilities that lead to the formation of rich quantum phases found in a wide range of physical systems including nuclei, cold atomic gases, and solids.
Correlation of the substitution position of diphenylphosphine oxide on phenylcarbazole and device performances of blue phosphorescent organic light-emitting diodes (2011)

Two diphenylphosphine oxide modified phenylcarbazole host materials with substituents at 2,7 (PPO27) and 3,6 (PPO36) positions were synthesized and their device performances were correlated with the chemical structure of the host materials. Low driving voltage was obtained in the PPO27host with two diphenylphosphine oxides at 2,7 positions due to reduced band gap. The PPO27 showed better performances in sky blue phosphorescent organic light-emitting diodes, while the PPO36 showed better performances in deep blue phosphorescent organic light-emitting diodes. A high quantum efficiency of 23.9% and power efficiency of 37.5 lm W−1 were achieved in the blue device with PPO27host.
Sensitivity of quantum information to environment perturbations measured with a nonlocal out-of-time-order correlation function (2020)

This work shows that by exploring the collective response of a many-body nuclear-spin system, the correlation between various parts of it can be studied. The appearance of the higher correlation orders, as a qubit shares its quantum information with the surrounding qubits, is used to measure quantum information flow.
Safety and effectiveness of rivaroxaban and warfarin in moderate-to-advanced CKD: real world data (2018)

Rivaroxaban seems a safe and effective therapeutic option in CKD stage 3b-4 patients. However, future randomized controlled trials are needed to definitively establish the role of rivaroxaban in CKD patients.
Evidence of universality in the dynamical response of micromechanical diamond resonators at millikelvin temperatures (2008)

We report kelvin to millikelvin-temperature measurements of dissipation and frequency shift in megahertz-range resonators fabricated from ultra-nanocrystalline diamond. Frequency shift $δf/f_0$ and dissipation $Q^{-1}$ demonstrate temperature dependence in the millikelvin range similar to that predicted by the glass model of tunneling two level systems. The logarithmic temperature dependence of $δf/ f_0$ is in good agreement with such models, which include phonon relaxation and phonon resonant absorption. Dissipation shows a weak power law, $Q^{-1}\propto T^{1/3}$, followed by saturation at low temperature. A comparison of both the scaled frequency shift and dissipation in equivalent micromechanical structures made of single-crystal silicon and gallium arsenide indicates universality in the dynamical response.
A Game Theoretic Framework for Power Control in Wireless Sensor Networks (2009)

In infrastructure-less sensor networks, efficient usage of energy is very critical because of the limited energy available to the sensor nodes. Among various phenomena that consume energy, radio communication is by far the most demanding one. One of the effective ways to limit unnecessary energy loss is to control the power at which the nodes transmit signals. In this paper, we apply game theory to solve the power control problem in a CDMA-based distributed sensor network. We formulate a noncooperative game under incomplete information and study the existence of Nash equilibrium. With the help of this equilibrium, we devise a distributed algorithm for optimal power control and prove that the system is power stable only if the nodes comply with certain transmit power thresholds. We show that even in a noncooperative scenario, it is in the best interest of the nodes to comply with these thresholds. The power level at which a node should transmit, to maximize its utility, is evaluated. Moreover, we compare the utilities when the nodes are allowed to transmit with discrete and continuous power levels; the performance with discrete levels is upper bounded by the continuous case. We define a distortion metric that gives a quantitative measure of the goodness of having finite power levels and also find those levels that minimize the distortion. Numerical results demonstrate that the proposed algorithm achieves the best possible payoff/utility for the sensor nodes even by consuming less power.

Principles Of Fusion Energy: An Introduction To Fusion Energy For Students Of Science And Engineering (2020)

This textbook accommodates the two divergent developmental paths which have become solidly established in the field of fusion energy: the process of sequential tokamak development toward a prototype and the need for a more fundamental and integrative research approach before costly design choices are made.Emphasis is placed on the development of physically coherent and mathematically clear characterizations of the scientific and technological foundations of fusion energy which are specifically suitable for a first course on the subject. Of interest, therefore, are selected aspects of nuclear physics, electromagnetics, plasma physics, reaction dynamics, materials science, and engineering systems, all brought together to form an integrated perspective on nuclear fusion and its practical utilization.The book identifies several distinct themes. The first is concerned with preliminary and introductory topics which relate to the basic and relevant physical processes associated with nuclear fusion. Then, the authors undertake an analysis of magnetically confined, inertially confined, and low-temperature fusion energy concepts. Subsequently, they introduce the important blanket domains surrounding the fusion core and discuss synergetic fusion-fission systems. Finally, they consider selected conceptual and technological subjects germane to the continuing development of fusion energy systems.
Stack-level validation of a semi-analytic channel-to-channel fuel cell model for two-phase water distribution boundary value control (2008)

A dynamic model combining analytic and numeric solutions to the partial differential equations (PDE) describing mass transport in the gas diffusion layers (GDL) of a fuel cell is verified by voltage prediction. The model estimates the effect of stack temperature changes, reactant gas concentration fluctuation, and excess liquid water (flooding) in the GDL. The semi-analytic model is more computationally efficient than a fully numeric model, and includes both anode and cathode channel dynamics enabling future boundary value control.
Remote control of the Fe magnetic moment in magnetic heterostructures (2007)

In magnetic superlattices with interlayer exchange coupling, not only the coupling strength but also the magnetic moment of the ferromagnetic layer can be altered non-locally by modifying the electronic structure of the non-magnetic spacer layer. Specifically, changes of the electronic structure of the V spacer layers in Fe/V (001) superlattices are seen to affect the adjacent Fe layers. By reversibly loading the V layer with hydrogen, the magnetic moment of Fe increases, whereas the induced magnetic moment in V remains unchanged. The nature of this remote and non-local control of the magnetic moment is connected with a &lt;em&gt;d&lt;/em&gt;-electron charge transfer and effective shift of the Fermi level relative to the &lt;em&gt;d&lt;/em&gt;-bands of Fe and V, as elucidated on the basis of self-consistent electronic structure calculations. © Europhysics Letters Association.
Immunity to murine sarcoma virus-inducted tumors. II. Suppression of T cell-mediated immunity by cells from progressor animals. (1974)

Experiments have been performed to examine the immune status in animals carrying tumors which are in their progressive phase of growth. Unfractionated spleen or lymph node cells of BALB/c mice, inoculated 10 to 14 days previously with murine sarcoma virus (MSV), have no demonstrable immunity in vitro to MSV-viral antigens. On fractionation of the spleen cells from such animals, however, large and small cells can be detected which react in well defined assays for immunity in this system. A cell population of intermediate size is capable of suppressing this activity. Treatment of the suppressing cell population with anti-θ or anti-immunoglobulin antiserum has provided data to suggest that the suppression is caused by a cell with immunoglobulin moieties on its surface. Moreover, evidence is presented to show that this suppression is nonspecific, in that the induction of protein synthesis in thymus-associated (T) cells in response to the mitogen phytohemagglutinin (PHA) is also suppressed by a cell with the above characteristics. The significance of these findings in relation to the status of growth of the tumor in the host is discussed.
Large electrical conductivity enhancement of WO3 thin films produced by ion implantation (1998)

Ion implantation induced dc electrical conductivity changes in polycrystalline WO3 thin films was examined. Helium, argon, and tungsten ions were implanted under the following conditions: helium at 90 keV, argon at 360 keV, and tungsten at 300 keV. The fluence range studied was from 1×1017 to 3×1017 cm−2 for helium and argon, and from 5×1014 to 5×1015 cm−2 for tungsten. The 300 K conductivities after implantation at a 1×1017 cm−2 fluence increased from ∼10−5 to ∼10−1 S cm−1 for helium implantation and to ∼102 S cm−1 for argon implantation. Also, implantation induced a broad optical absorption feature at ∼1000 nm and a negative thermopower coefficient indicating n-type conduction. The implanted samples exhibited low conductivity activation energies, which were consistent with degenerate conduction. Tungsten implantation induced conductivities were higher than those resulting from either helium or argon implantation as a conductivity of ∼102 S cm−1 was obtained at a 5×1015 cm−2 fluence. These conductivity changes are correlated to the displacements per atom resulting from the various ion implantations. Several mechanisms are responsible for the observed donor species increase: (1) in the proton case the implanted species becomes a donor, (2) in the helium and argon cases a charged oxygen vacancy may be formed by the nuclear collisions that occur during implantation, and (3) in the tungsten case the subsequent oxidation of the implanted tungsten results in the formation of a donor species.
Internet packet loss: measurement and implications for end-to-end QoS (2002)

We analyze a month of Internet packet loss statistics for speech transmission using three different sets of transmitter/receiver host pairs. Our results indicate that packet loss is highly bursty, with the majority of individual losses occurring in a relatively small number of bursts. We find that loss exhibits dependence in most cases, but is not always well modeled as dependent. We introduce an analytical technique for measuring loss dependency. We also consider the asymmetry of round trip packet loss, and find that most loss on a round trip path occurs in either one direction or the other. We introduce a normalized metric for measuring loss asymmetry and apply it to our measurements. Finally we discuss the implications of our study for the next generation of real time voice services in the Internet.

The vicilin gene family of pea (Pisum sativumL.): a complete cDNA coding sequence for preprovicilin (1983)

A cDNA plasmid bank has been constructed using mRNA from developing pea seeds and three cDNAs coding for vicilin polypeptides have been selected. These cDNAs have been sequenced and between them cover the whole of the coding sequence plus part of the 5' and 3' untranslated regions. Comparison with amino acid sequence data from the protein indicates that vicilin is synthesised as preprovicilin with subsequent removal of a signal peptide and a C-terminal peptide as well as post translational endo-proteolytic cleavage. The cDNAs represent two different classes of vicilin genes whilst amino acid data show that there are at least three major classes of vicilin polypeptide. The vicilin sequences show extensive homology with conglycinin and phaseolin except in the regions of the internal proteolytic cleavages. The evolutionary significance of this relationship is discussed.
