Data cache locking for higher program predictability (2003)

Caches have become increasingly important with the widening gap between main memory and processor speeds. However, they are a source of unpredictability due to their characteristics, resulting in programs behaving in a different way than expected.Cache locking mechanisms adapt caches to the needs of real-time systems. Locking the cache is a solution that trades performance for predictability: at a cost of generally lower performance, the time of accessing the memory becomes predictable.This paper combines compile-time cache analysis with data cache locking to estimate the worst-case memory performance (WCMP) in a safe, tight and fast way. In order to get predictable cache behavior, we first lock the cache for those parts of the code where the static analysis fails. To minimize the performance degradation, our method loads the cache, if necessary, with data likely to be accessed.Experimental results show that this scheme is fully predictable, without compromising the performance of the transformed program. When compared to an algorithm that assumes compulsory misses when the state of the cache is unknown, our approach eliminates all overestimation for the set of benchmarks, giving an exact WCMP of the transformed program without any significant decrease in performance.
Stereoselective Synthesis of Chiral α-SCF3-β-Ketoesters Featuring a Quaternary Stereocenter (2021)

The development of new and efficient methods, reagents, and catalysts for the introduction of fluorine atoms or fluorinated moieties in molecular scaffolds has become a topic of paramount importance in organic synthesis. In this framework, the incorporation of the SCF3 group into organic molecule has often led to beneficial effects on the drug’s metabolic stability and bioavailability. Here we report our studies aimed to the stereoselective synthesis of chiral α-SCF3-β−ketoesters featuring a tetrasubstituted stereocenter. The use of a chiral auxiliary was crucial to synthesize enantiopure enamines that were reacted with N-trifluoromethylthio saccharin or phthalimide, to afford enantioenriched α-SCF3-tetrasubstitued β-keto esters. By using a readily available, inexpensive chiral diamine, such as trans-1,2-diaminocyclohexane, the fluorinated products could be obtained in modest to good yields, and, after the removal of the chiral auxiliary, α-substituted- α trifluoromethylthio-β−ketoesters were isolated with high enantioselectivity (up to 91% ee).
Mutation of Fnip1 is associated with B-cell deficiency, cardiomyopathy, and elevated AMPK activity (2016)

Folliculin (FLCN) is a tumor-suppressor protein mutated in the Birt-Hogg-Dubé (BHD) syndrome, which associates with two paralogous proteins, folliculin-interacting protein (FNIP)1 and FNIP2, forming a complex that interacts with the AMP-activated protein kinase (AMPK). Although it is clear that this complex influences AMPK and other metabolic regulators, reports of its effects have been inconsistent. To address this issue, we created a recessive loss-of-function variant of Fnip1 Homozygous FNIP1 deficiency resulted in profound B-cell deficiency, partially restored by overexpression of the antiapoptotic protein BCL2, whereas heterozygous deficiency caused a loss of marginal zone B cells. FNIP1-deficient mice developed cardiomyopathy characterized by left ventricular hypertrophy and glycogen accumulation, with close parallels to mice and humans bearing gain-of-function mutations in the γ2 subunit of AMPK. Concordantly, γ2-specific AMPK activity was elevated in neonatal FNIP1-deficient myocardium, whereas AMPK-dependent unc-51-like autophagy activating kinase 1 (ULK1) phosphorylation and autophagy were increased in FNIP1-deficient B-cell progenitors. These data support a role for FNIP1 as a negative regulator of AMPK.
1200 V GaN vertical fin power field-effect transistors (2017)

We demonstrate record performance in a novel normally-off GaN vertical transistor with submicron finshaped channels. This vertical fin transistor only needs n-GaN layers, with no requirement for epitaxial regrowth or p-GaN layers. A specific on-resistance of 0.2 mfì-cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and a breakdown voltage over 1200 V have been demonstrated with extremely high ON current (over 25 kA/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) and low OFF current at 1200 V (below 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-4</sup> A/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ), rendering an excellent Baliga's figure of merit up to 7.2 GW/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . A threshold voltage of 1 V was achieved and was stable up to 150 °C. Large devices with high current up to 10 A and breakdown voltage over 800 V were also demonstrated. These results show the great potential of GaN vertical fin transistors for high-current and high-voltage power applications.
High energy-transfer rate from Sn^2+ to Mn^2+ in phosphate glasses (2015)

High energy-transfer rates from Sn2+ to Mn2+ centers are demonstrated in ZnO–P2O5 glass. Emission decay curves of Sn2+ suggest an energy exchange interaction between Sn2+ and Mn2+. It is notable that the high energy-transfer rates are attained for random phosphate glass and that the transfer rate becomes slower with increasing amounts of Mn2+. Because these glasses possess high internal quantum efficiencies independent of the Sn2+ or Mn2+ concentration, we emphasize that effective energy-transfer paths are generated in the transparent glass phosphor, which leads to the development of a transparent inorganic light-emitting material different from conventional rare-earth-containing powdered phosphors.

Towards Integrated Powertrain Control for a Mild-Hybrid Urban Vehicle with a Downsized Turbo-Charged CNG Engine (2007)

Compressed natural gas (CNG) is considered as one of the most promising alternative fuels for transportation due to its ability to reduce greenhouse gas emissions (CO2, in particular) and its abundance. An earlier study from IFP has shown that CNG has a considerable potential when used as a fuel for a dedicated downsized turbo-charged SI engine on a small urban vehicle. To take further advantage of CNG assets, this approach can be profitably extended by adding a small secondary (electrical) power source to the CNG engine, thus hybridizing the powertrain. This is precisely the focus of the new IFP project, VEHGAN, which aims to develop a mild-hybrid CNG prototype vehicle based on a MCC Smart car equipped with a reversible starter-alternator and ultra-capacitors (Valeo Starter Alternator Reversible System, StARS). The unfolding of this project has involved and will involve several interesting and challenging issues from an engine control point of view, such as mastering the automatic manual transmission (AMT) control system and integrating a new power source, with its new functions, into the torque-oriented engine control structure.

Splitting of microcavity degenerate modes in rotating photonic crystals—the miniature optical gyroscopes (2006)

A manifestation of the Sagnac effect in a rotating photonic crystal that contains a microcavity with degenerate modes is explored. It is shown that generally rotation can cause the resonance frequency to split into M different frequencies, where M is the order of the stationary-system mode degeneracy. The results are derived using a new rotation-induced eigenvalue theory that holds for any two-dimensional or three-dimensional rotating microcavity with mode degeneracy. Comparison with exact numerical simulations of the rotating system is provided. Miniature optical gyroscopes are discussed.
PixelMaps: a new visual data mining approach for analyzing large spatial data sets (2004)

PixelMaps are a new pixel-oriented visual data mining technique for large spatial datasets. They combine kernel-density-based clustering with pixel-oriented displays to emphasize clusters while avoiding overlap in locally dense point sets on maps. Because a full evaluation of density functions is prohibitively expensive, we also propose an efficient approximation, Fast-PixelMap, based on a synthesis of the quadtree and gridfile data structures.
Temporarily implanted urethral coil stent for the treatment of recurring urethral strictures: (UROCOIL). (1990)

Effects of Optical Distortion on Focusing Characteristics of CO2 Laser. (1994)

Focusing characteristics of CO2 laser beam affected by an optical distortion are calculated for a Gaussian mode and higher order modes using computer simulation, which gives a theoretical dependence of the optical distortion on the transverse intensity profiles. The theoretical results show that the beam with higher intensity at a center region gives more serious distortion effect for focusing than the beam with lower intensity at a center region.
Changes in the Luteinizing Hormone Content of the Rat Pars tuheralis during the Estrus Cycle and after Lesions in the Preoptic Area (1982)

The rat pars tuberalis was studied with conventional electron microscopy and immunocytochemistry for the demonstration of luteinizing hormone (LH). The LH-secreting cells were preferentially located in two regions of the pars tuberalis (PT), namely, that surrounding the neural stalk and that occupying the tuberoinfundibular sulci. Dialyzed extracts of PT prepared after removal of the pituitary stalk, had the capacity to induce ovulation in chlorpromazine-blocked rats in proestrus. In radioimmunoassays carried out under the same conditions, the PT extracts yielded displacement curves parallel to those of standard LH. The immunoreactive LH content of the female PT was determined at three phases of the estrous cycle: diestrus, afternoon of proestrus and estrus. The lowest values were found in rats sacrificed in the evening of proestrus (18.00 h), and they were about one sixth of the peak values found at estrus. 1 month after inducing lesions in the preoptic area of female rats, the LH content of the PT was four times higher than the highest values found during the estrous cycle. The results suggest that the rat PT does secret LH, and that this secretory activity fluctuates with the estrous cycle, but in a manner that differs from that reported for LH secretion of the pars distalis.
Finite aperture correction for spectral cameras with integrated thin-film Fabry–Perot filters (2018)

Spectral cameras with integrated thin-film Fabry-Perot filters enable many different applications. Some applications require the detection of spectral features that are only visible at specific wavelengths, and some need to quantify small spectral differences that are undetectable with RGB color cameras. One factor that influences the central wavelength of thin-film filters is the angle of incidence. Therefore, when light is focused from an imaging lens onto the filter array, undesirable shifts in the measured spectra are observed. These shifts limit the use of the sensor in applications that require fast lenses or lenses with large chief ray angles. To increase flexibility and enable new applications, we derive an analytical model that explains and can correct the observed shifts in measured spectra. The model includes the size of the aperture and physical position of each filter on the sensor. We experimentally validate the model with two spectral cameras: one in the visible and near-infrared region and one in the short wave infrared region.
Master Maker: Understanding Gaming Skill Through Practice and Habit From Gameplay Behavior (2017)

The study of expertise is difficult to do in a laboratory environment due to the challenge of finding people at different skill levels and the lack of time for participants to acquire mastery. In this paper, we report on two studies that analyze naturalistic gameplay data using cohort analysis to better understand how skill relates to practice and habit. Two cohorts are analyzed, each from two different games (Halo Reach and StarCraft 2). Our work follows skill progression through 7 months of Halo matches for a holistic perspective, but also explores low-level in-game habits when controlling game units in StarCraft 2. Players who played moderately frequently without long breaks were able to gain skill the most efficiently. What set the highest performers apart was their ability to gain skill more rapidly and without dips compared to other players. At the beginning of matches, top players habitually warmed up by selecting and re-selecting groups of units repeatedly in a meaningless cycle. They exhibited unique routines during their play that aided them when under pressure.
Space vector modulation: an engineering review (1990)

The space vector pulse width modulation (PWM) technique has rapidly gained favour among industrial drives manufacturers as an alternative to the traditional regularly sampled triangulation method. The authors present a practical engineering comparison between the two modulation techniques and show that the space vector technique inherently generates a 'superior' PWM waveform. In particular the waveforms are easier to generate with a microprocessor in real-time, they cause significantly lower motor losses, and motor stability problems are reduced as the current zero crossings are improved. The waveforms can be generated with essentially the same hardware so that all these advantages are available for zero additional cost.<

Noncovalent interaction between amyloid-β-peptide (1–40) and oleuropein studied by electrospray ionization mass spectrometry (2006)

Beta amyloid peptide (Abeta) is the major proteinaceous component of senile plaques formed in Alzheimer's disease (AD) brain. The aggregation of Abeta is associated with neurodegeneration, loss of cognitive ability, and premature death. It has been suggested that oxidative stress and generation of free radical species have implications in the fibrillation of Abeta and its subsequent neurotoxicity. For this reason, it is proposed that antioxidants may offer a protective or therapeutic alternative against amyloidosis. This study is the first report of the formation of the noncovalent complex between Abeta or its oxidized form and the natural derived antioxidant oleuropein (OE) by electrospray ionization mass spectrometry (ESI MS). ESI MS allowed the real time monitoring of the complex formation between Abeta, OE, and variants thereof. Several experimental conditions, such as elevated orifice potential, low pH values, presence of organic modifier, and ligand concentration were examined, to assess the specificity and the stability of the formed noncovalent complexes.
11.2 A 10.8ps-time-resolution 256&#x00D7;512 image sensor with 2-Tap true-CDS lock-in pixels for fluorescence lifetime imaging (2015)

Fluorescence lifetime imaging microscopy (FLIM), which is a nondestructive and minimally invasive manner and can therefore be applied to living cells and tissues, is a great analysis tool in fundamental physics as well as in the life sciences. Charge-coupled devices (CCDs) [1] and single-photon avalanche diodes (SPADs) [2,3] are used for time-resolved lifetime measurement. In particular, SPAD-based time-resolved imagers have a high single-photon sensitivity and good noise robustness. However, they consist of a SPAD array with pixel circuitry, time-to-digital converters (TDCs), digital integrators to amplify signals, and readout circuitry. To implement the high photon-counting rate, a large number of TDCs and digital integrators are required. The spatial resolution of the SPAD-based time-resolved imagers is limited on this account. A recently reported time-resolved CMOS imager [4] using a draining-only modulation (DOM) technique has an attractive feature that a very simple pixel structure and 2-stage charge transfer without transfer gate (TG) can be simultaneously attained. However, it has a small aperture area, a comparatively low transfer speed, and multiple outputs are a challenge.

IIn this paper, we describe a C-band high power amplifier(HPA) Monolithic Microwave Integrated Circuit(MMIC) design and measurement results for satellite transmitters. For a high output power of 20 W, a 0.25 μm GaN process was used and the HPA MMIC with a 2-stage cascade configuration was operated in Class AB mode for high efficiency. The fabricated MMIC has 29 dB gain, 43.3 dBm output power, and 48 % power added efficiency(PAE) with an MMIC size of 3.0 mm×1.8 mm over a frequency range from 5.0 GHz to 7.2 GHz and exhibits an output power density of 3.96 W/mm2.
Characterization of a De Novo Conversion in Human Complement C4 Gene Producing a C4B5-Like Protein (2002)

Complement C4 is a highly polymorphic protein essential for the activation of the classical complement pathway. Most of the allelic variation of C4 resides in the C4d region. Four polymorphic amino acid residues specify the isotype and an additional four specify the Rodgers and Chido determinants of the protein. Rare C4 allotypes have been postulated to originate from recombination between highly homologous C4 genes through gene conversions. Here we describe the development of a de novo C4 hybrid protein with allotypic and antigenic diversity resulting from nonhomologous intra or interchromosomal recombination of the maternal chromosomes. A conversion was observed between maternal C4A3a and C4B1b genes producing a functional hybrid gene in one of the children. The codons determining the isotype, Asp(1054), Leu(1101), Ser(1102), Ile(1105) and His(1106), were characteristic of C4B gene, whereas the polymorphic sites in exon and intron 28 were indicative of C4A3a sequence. The protein produced by this hybrid gene was electrophoretically similar to C4B5 allotype. It also possesses reversed antigenicity being Rodgers 1, 2, 3 and Chido-1, -2, -3, 4, -5, and -6. Our case describes the development of a rare bimodular C4B-C4B haplotype containing a functional de novo C4 hybrid gene arisen through gene conversion from C4A to C4B. Overall the data supports the hypothesis of gene conversions as an ongoing process increasing allelic diversity in the C4 locus.

Evaluation of ultra-compact rectifiers for low power, high-speed, permanent-magnet generators (2009)

Literature reports several future portable and distributed power supplies in the watt to kilowatt range based on rotating machinery equipped with a variable-speed permanent-magnet generator. In order to generate a constant dc voltage, an ultra-compact, highly efficient, low power rectifier is required. In this paper, different topologies are compared concerning losses, volume and control complexity. The most suitable, the half controlled three-phase PWM boost rectifier (HCBR) is selected and evaluated, and a novel modulation scheme enhancing the power electronics efficiency is proposed. The integration into a compressed-air-to-electric-power-system with a generator rotating at 350 000 rpm is presented including measurement results.
