Augmented RFID Tags (2016)

This paper discusses the evolution of UHF RFID tags towards Augmented Tags. Such an evolution must be compliant with the huge advantages that the tags encompass, in particular full passive feature, compact size, usage flexibility and cost effectiveness. The discussed evolutions are based on the exploitation of some of the properties of the tag antennas or the RFID chips. Indeed, it is well established that any modification introduced in the near field region of antenna will generate significant change in its parameters such as impedance and directivity. Therefore it could be used as an environment sensor. Besides, the non-linear behavior of RFID chip could be used to implement new functions such as energy harvesting and communication channel diversity. Moreover, the design of RFID chip can evolve to allow the integration of external sensor.
A phenomenological approach to the inversion of the helical twist sense in the chiral nematic phase (1998)

Optically active materials that show a temperature dependent inversion of the helical twist sense in the chiral smectic C* and chiral nematic phases have been known for many years. However, it has only recently been found that inversions can occur in compounds which have single chiral centres. It was found previously that the temperature range and the magnitude and sign of the helical twist in the chiral nematic phase are related to the concentration of the optically active material(s) dissolved in a nematic host. In a similar way, we propose to describe the inversion of the helical twist sense in the chiral nematic phase of pure materials containing a single chiral centre. Additionally, we seek to verify the possible validity of the latter model by means of molecular modelling on appropriate compounds, and by deriving a suitable mathematical expression to allow the direct use of experimental data.
Performance assessment of RF power amplifier memory polynomial models under different signal statistics (2009)

Memory polynomial models are widely used in the behavioural modelling and linearization of RF power amplifiers (PAs). In this paper we assess the performances of theses models under different signal bandwidths, statistics and power distributions. For this purpose, Normalized mean square error (NMSE) has been used to compare the model output to measured data when the PA is driven by different input signals. Several simulations and measurements have been carried out and the results demonstrated the effects of the signal characteristics on the performances of the model. Real multi carrier WCDMA and multi tone signals were used with an experimental Doherty amplifier. The obtained results revealed a degradation of the polynomial model performances when the statistics of the input signals change.

Losartan in Combination With Bone Marrow Stimulation Showed Synergistic Effects on Load to Failure and Tendon Matrix Organization in a Rabbit Model (2023)

Tendon healing or scarring is accompanied by the formation of fibrosis, which has been shown to result in compromised biomechanical properties, and is therefore a potential limiting factor in healing after rotator cuff repair. TGF-β1 expression has been shown to play an important role in the formation of fibrosis. Recent studies focusing on muscle healing and cartilage repair have found that the downregulation of TGF-β1 by losartan intake can reduce fibrosis and improve tissue regeneration in animal models.
Device line characterization of Gunn diodes using six-port techniques (2002)

A device line characterization system using a six-port reflectometer with a built-in impedance tuner is reported. Device line measurements on a Gunn diode mounted in a coaxial fixture were performed at the Ka-band to optimize experimentally the output microwave power in the oscillation mode. In addition to its relatively low cost, an inherent advantage of the instrumentation used is that the large-signal reflection coefficient of negative resistance devices can be measured at the actual power level that exists in practice.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Occlusive thrombosis in the rabbit auricular vein in vivo targeted by induction of intralumenal cavitation using HIFU and ultrasound contrast agent (2005)

Hypotheses tested: (1) inertial cavitation [IC] could be induced in the venous lumen in vivo by combined use of intravascular microbubble contrast agent and transcutaneous application of 1-MHz high intensity focused ultrasound [HIFU] of very low duty factor, and that IC activity could be detected and quantified in vivo as in earlier in vitro studies via passive cavitation detection methods; (2) robust IC activity would damage the venous endothelium in treated regions; (3) endothelial damage would be proportional to the IC dose developed in the region; (4) severe local endothelial damage alone may be sufficient to induce occlusive thrombosis, or may sensitize the region to low systemic doses of prothrombotic agents, and (5) biologically significant temperature rises and attendant thermal bioeffects in the vessel and perivascular tissues would not occur, even under the highest amplitude acoustic conditions applied. Each hypothesis was supported by the data. The principal result was that under treatment conditions involving very high peak negative acoustic pressures and contrast agent, treated areas thrombosed acutely but non-occlusively. When fibrinogen was administered locally after such treatment, occlusive thrombi formed acutely and only in the treated region, a response observed with none of the other treatments.
GSM voice evolution using orthogonal subchannels (2012)

The explosive growth of mobile communications, and the overly crowded and expensive spectrum have pushed both system engineers and operators to make their systems as spectrally efficient as possible in order to accommodate the increasing traffic demand. This article is a tutorial introduction to the orthogonal subchannel (OSC) technique. OSC was adopted to improve the capacity of the GSM/EDGE radio access network GERAN, and it is a new concept in which two users can simultaneously share the same GSM radio resource (time slot and frequency) in both the downlink and in uplink directions. Potentially, OSC could not only provide increased network capacity, but also reduce network-associated costs through more efficient usage of hardware and spectrum resources. In addition, this article presents some challenges related to this method, as well as solutions and their respective impact. The results provided herein may contribute to guidelines for network dimensioning and optimization, as well as list potential enhancements to the OSC radio resource management mechanisms needed to further exploit the benefits of OSC. Currently, in real OSC network deployments a capacity gain of 50 percent has been achieved at the cell level. As an indication of the importance of OSC, GSMA awarded it (called Quad Rate) the Best Technology Breakthrough award at Mobile World Congress 2012 [1].

Structure of the Retinoid X Receptor α DNA Binding Domain: a Helix Required for Homodimeric DNA Binding (1993)

The three-dimensional solution structure of the DNA binding domain (DBD) of the retinoid X receptor alpha (RXR alpha) was determined by nuclear magnetic resonance spectroscopy. The two zinc fingers of the RXR DBD fold to form a single structural domain that consists of two perpendicularly oriented helices and that resembles the corresponding regions of the glucocorticoid and estrogen receptors (GR and ER, respectively). However, in contrast to the DBDs of the GR and ER, the RXR DBD contains an additional helix immediately after the second zinc finger. This third helix mediates both protein-protein and protein-DNA interactions required for cooperative, dimeric binding of the RXR DBD to DNA. Identification of the third helix in the RXR DBD thus defines a structural feature required for selective dimerization of the RXR on hormone response elements composed of half-sites (5'-AGGTCA-3') arranged as tandem repeats.
High frequency thickness expansion mode bulk acoustic wave resonator using LN single crystal thin plate (2020)

Abstract In this report, a thickness expansion mode film bulk acoustic resonator (FBAR) was fabricated using 4 μ m thick 36°Y-LiNbO 3 (LN) single crystal thin plate. The LN thin plate was made by polishing after bonded to a Si bare wafer. The LN FBAR showed a bandwidth of 10.3% and an impedance ratio of 45 dB at 800 MHz. The spurious response due to a thickness shear (TS) mode was much smaller than the main mode, because the optimal cut angle was chosen. The quality factor of anti-resonance is poor probably due to acoustic loss caused by a misalignment of the upper and lower electrodes, the series connection of two resonators etc. By minimizing the acoustic loss, the impedance ratio can be improved up to 60 dB.
Back to the future: Forecasting program behavior in automated homes (2012)

Networked devices such as locks and thermostats are now cheaply available, which is accelerating the adoption of home automation. But unintended behaviors of programs that control automated homes can pose severe problems, including security risks (e.g., accidental disarming of alarms). We facilitate predictable control of automated homes by letting users “fast forward” their program and observe its possible future behaviors under different sequences of inputs and environmental conditions. A key challenge that we face, which is not addressed by existing program exploration techniques, is to systematically handle time because home automation programs depend intimately on absolute and relative timing of inputs. We develop an approach that models programs as timed automata and incorporates novel mechanisms to enable scalable and comprehensive exploration of their behavior. We implement our approach in a tool called DeLorean and apply it to 10 real home automation programs. We find that it can fast forward these programs 3.6 times to 36K times faster than real time and uncover unintended behaviors in them.
A phase 2 randomized multicenter study of 2 extended dosing schedules of oral ezatiostat in low to intermediate‐1 risk myelodysplastic syndrome (2011)

Ezatiostat is the first GSTP1-1 inhibitor shown to cause clinically significant and sustained reduction in RBC transfusions, transfusion independence, and multilineage responses in MDS patients. The tolerability and activity profile of ezatiostat may offer a new treatment option for patients with MDS.
Polyunsaturated fatty acid deficiency during neurodevelopment in mice models the prodromal state of schizophrenia through epigenetic changes in nuclear receptor genes (2017)

The risk of schizophrenia is increased in offspring whose mothers experience malnutrition during pregnancy. Polyunsaturated fatty acids (PUFAs) are dietary components that are crucial for the structural and functional integrity of neural cells, and PUFA deficiency has been shown to be a risk factor for schizophrenia. Here, we show that gestational and early postnatal dietary deprivation of two PUFAs-arachidonic acid (AA) and docosahexaenoic acid (DHA)-elicited schizophrenia-like phenotypes in mouse offspring at adulthood. In the PUFA-deprived mouse group, we observed lower motivation and higher sensitivity to a hallucinogenic drug resembling the prodromal symptoms in schizophrenia. Furthermore, a working-memory task-evoked hyper-neuronal activity in the medial prefrontal cortex was also observed, along with the downregulation of genes in the prefrontal cortex involved in oligodendrocyte integrity and the gamma-aminobutyric acid (GABA)-ergic system. Regulation of these genes was mediated by the nuclear receptor genes Rxr and Ppar, whose promoters were hyper-methylated by the deprivation of dietary AA and DHA. In addition, the RXR agonist bexarotene upregulated oligodendrocyte- and GABA-related gene expression and suppressed the sensitivity of mice to the hallucinogenic drug. Notably, the expression of these nuclear receptor genes were also downregulated in hair-follicle cells from schizophrenia patients. These results suggest that PUFA deficiency during the early neurodevelopmental period in mice could model the prodromal state of schizophrenia through changes in the epigenetic regulation of nuclear receptor genes.
Hybrid Quantum-Classical Approach to Correlated Materials (2016)

Quantum computers promise to shed light on many areas of research that have proven too computationally expensive even for current supercomputers. Researchers show how a hybrid quantum-classical approach can be used to simulate strongly correlated materials, such as high-temperature superconductors and transition-metal oxides.
A Proposal to Realize the Provision of Secure Android Applications -- ADMS: An Application Development and Management System (2012)

To realize the provision of secure Android applications, this paper proposes an application development and management system, or ADMS for short, that is operated and maintained by application developers and the market manager. ADMS requires (i) Android OS to be equipped with a "security manager", (ii) all application developers to embed a code for event notification into applications to tell every event to the security manager whenever an application launches a security-related event, and (iii) market manager to remove all such applications that don't include the event notification code.
Novel dual-mode photoresist based on decarboxylation by photogenerated base compound (1998)

The copolymers containing a carboxyl group were used as the two-component photopolymers in combination with dimethyl 4-(o-nitrophenyl)-2,6-dimethyl-1,4-dihydro-3,5-pyridinedicarboxylate (NMHP) as a photobase generator. Under irradiation by 365 nm light, NMHP is converted to dimethyl 4-(o-nitrosophenyl)-2,6-dimethyl-3,5-pyridinedicarboxylate (NMP). NMP acts as a base catalyst for the thermal decarboxylation of a carboxyl group in the polymer. The decarboxylation in the polymer provides a negative-working photoresist under the additional flood-exposure of 365 nm light before development. This process is called the photoassisted contrast (PAC) process. NMHP acts as a dissolution inhibitor for the aqueous base development of the polymers containing a carboxyl group but NMP promotes the dissolution of the polymers. This change in the solubility inhibition of NMHP offers a positive-working photoresist without the process of post-exposure baking (PEB) and the PAC process. Therefore, NMP, the photoproduct of NMHP, produces dual-tone-mode photoresists with the copolymers containing a carboxyl group. © 1998 John Wiley & Sons, Ltd.
Gear Fault Location Detection for Split Torque Gearbox using AE Sensors (2010)

&#x0D; &#x0D; &#x0D; In comparison with a traditional planetary gearbox, the split torque gearbox (STG) potentially offers lower weight, increased reliability, and improved efficiency. These benefits have driven helicopter OEMs to develop products using STG. However, the effect of multiple gears meshing simultaneously with the central gear and a large number of synchronous components (gears or bearing) in close proximity creates a problem on how to detect the gear fault location in a STG. As of today, only limited research on STG fault detection using vibration sensors and acoustic emission sensors has been conducted.In this paper, an effective methodology on gear fault location detection using AE sensors for STG is presented. The methodology uses wavelet transform to process the AE sensor signals to determine the arrival time of the AE bursts at different locations. By analyzing the arrival times of the AE bursts, the gear fault location can be determined. The parameters of the wavelet transform are optimized by using an ant colony optimization algorithm. Real seeded gear fault experimental tests on a notational STG are conducted. AE sensor signals at the locations of healthy and damaged output driving gears are collected simultaneously to determine the location of the damaged gear. Experimental results have shown the effectiveness of the presented methodology.&#x0D; &#x0D; &#x0D;
Structural identification of mouse urinary metabolites of pterostilbene using liquid chromatography/tandem mass spectrometry (2010)

Pterostilbene, the dimethoxy derivative of resveratrol, has drawn much attention recently due to its potential beneficial health effects. The metabolic fate of pterostilbene, however, is not well understood. In the present study, we identified nine novel mouse urinary pterostilbene metabolites, pterostilbene glucuronide, pterostilbene sulfate, mono-demethylated pterostilbene glucuronide, mono-demethylated pterostilbene sulfate, mono-hydroxylated pterostilbene, mono-hydroxylated pterostilbene glucuronide, mono-hydroxylated pterostilbene sulfate, and mono-hydroxylated pterostilbene glucuronide sulfate, using liquid chromatography/atmospheric pressure chemical ionization and electrospray ionization tandem mass spectrometry. The structures of these metabolites were confirmed by analyzing the MS(n) (n = 1-3) spectra. To our knowledge, this is the first report of the identification of urinary metabolites of pterostilbene in mice.
Wave Function Engineering in Elongated Semiconductor Nanocrystals with Heterogeneous Carrier Confinement (2005)

We explore two routes to wave function engineering in elongated colloidal CdSe/CdS quantum dots, providing deep insight into the intrinsic physics of these low-dimensional heterostructures. Varying the aspect ratio of the nanoparticle allows control over the electron-hole overlap (radiative rate), and external electric fields manipulate the interaction between the delocalized electron and the localized hole. In agreement with theory, this leads to an exceptional size dependent quantum confined Stark effect with field induced intensity modulations, opening applications as electrically switchable single photon sources.
Impact of Sediment Resuspension Events on the Availability of Heavy Metals in Freshwater Sediments (2012)

Release of heavy metals during sediment resuspension is an understudied problem that may be cause for environmental concern. Common activities such as shipping and dredging have the ability to resuspend large amounts of contaminated anoxic sediment into the overlying water column. Oxidation of anoxic sediment can alter metal binding, potentially releasing metals into the water column. Understanding fate, bioavailability, and transport of metals is ecologically important, and key to creating more accurate metal speciation and transport models to predict environmental impacts. A Sediment Flux Exposure Chamber (SeFEC) was used to resuspend four types of contaminated sediment to replicate different resuspension scenarios. Dissolved metal concentrations were measured to determine the percent of total metal released. AVS and SEM values were measured to gauge sediment toxicity. Pyrocystis lunula (dinoflagellate) Daphnia magna (zooplankton) and Hyallela azteca (amphipod) were exposed to resuspension conditions to assess biotic endpoints No significant mortality of D. magna and H. azteca was seen. P. lunula exhibited decreased bioluminescence when exposed to bedded sediments, but exhibited mixed responses with resuspended water column samples. . Release of heavy metals to the water column occurred during resuspension. Both increasing and decreasing concentrations were seen through time during consecutive resuspension events.. The findings allow for better determination of the ecological relevance of resuspension events and further the development of metal speciation models by tracing the transport of heavy metals during resuspension events.
