Strain monitoring of drilling riser in deepwater based on fiber Bragg gratings (2011)

It is very important to monitor the lateral and axial strains of drilling riser for evaluation its health in deepwater. An optical fiber strain sensing system based on optical fiber Bragg gratings (FBGs) used for monitoring the strain of drilling riser is presented. The optical fiber strain sensors are made by embedding FBGs into thin columned fiber reinforced polymer which protect FBGs from seawater corrosion. Four optical fiber strain sensors are installed parallel to the riser axis and arranged at 90&deg; angles around the riser by a home-made metal belt, at the same time, twelve resistance strain gauges are pasted near the sensors around the drilling riser at 30&deg; angles as reference sensors. A scaled drilling riser about 1 meter long and 0.245m diameter is pressed in the lateral and axial direction in the range of 0-400KN, the experimental results show that the relative error between optical fiber strain sensors and resistance strain gauges is less than 6%.

Broad-Spectrum, Potent, and Durable Ceria Nanoparticles Inactivate RNA Virus Infectivity by Targeting Virion Surfaces and Disrupting Virus–Receptor Interactions (2023)

There is intense interest in developing long-lasting, potent, and broad-spectrum antiviral disinfectants. Ceria nanoparticles (CNPs) can undergo surface redox reactions (Ce<sup>3+</sup> ↔ Ce<sup>4+</sup>) to generate ROS without requiring an external driving force. Here, we tested the mechanism behind our prior finding of potent inactivation of enveloped and non-enveloped RNA viruses by silver-modified CNPs, AgCNP1 and AgCNP2. Treatment of human respiratory viruses, coronavirus OC43 and parainfluenza virus type 5 (PIV5) with AgCNP1 and 2, respectively, prevented virus interactions with host cell receptors and resulted in virion aggregation. Rhinovirus 14 (RV14) mutants were selected to be resistant to inactivation by AgCNP2. Sequence analysis of the resistant virus genomes predicted two amino acid changes in surface-located residues D91V and F177L within capsid protein VP1. Consistent with the regenerative properties of CNPs, surface-applied AgCNP1 and 2 inactivated a wide range of structurally diverse viruses, including enveloped (OC43, SARS-CoV-2, and PIV5) and non-enveloped RNA viruses (RV14 and feline calicivirus; FCV). Remarkably, a single application of AgCNP1 and 2 potently inactivated up to four sequential rounds of virus challenge. Our results show broad-spectrum and long-lasting anti-viral activity of AgCNP nanoparticles, due to targeting of viral surface proteins to disrupt interactions with cellular receptors.
Coverage Study for VoIP over Enhanced Uplink (2006)

In this paper, the coverage of VoIP over enhanced uplink (EUL) is investigated and compared with the coverage of the traditional circuit switched AMR 12.2 kbps speech and 64 kbps data services. A propagation model is used to analyze the coverage for different cases. The coverage of EUL depends on a number of parameters, such as TTI length, number of retransmissions and relative channel power allocation. The simulations show better coverage for EUL using a TTI of 10 ms than 2 ms under comparable conditions, considering the same delay budget. Furthermore, in most of the cases the coverage of VoIP over EUL is comparable or even better than that of CS 64 kbps. VoIP over EUL has the potential to have a comparable or even better coverage than CS AMR 12.2 kbps if more power is allocated to EUL data channel and more transmission attempts are allowed

Different mechanism to explain the 1∕f noise in n- and p-SOI-MOS transistors fabricated on (110) and (100) silicon-oriented wafers (2009)

The investigation of the low frequency noise in p- and n-channel semiconductor-on-insulator–metal oxide semiconductor transistors fabricated on (100) and (110) silicon-oriented wafers using high advanced processes has been carried out. While for both orientations the 1∕f noise in the n-channel transistors can be explained through the ΔN formalism, the p-channel ones seem to follow the Hooge model. In addition, the new orientation presents a noise level higher than the conventional one. Furthermore, the authors showed that when there is a gap of one decade between the Si(100) and Si(110) p-channel transistors, this one has been reduced to a factor of 2 in the case of the n-channel ones. Finally, by combining the highly advanced microwave-excited high-density plasma oxidation process with the alkali-free five-step cleaning process, it has been possible to fabricate on both surfaces a very high quality oxide with a very low density of traps.
Coordinated lateral and longitudinal vehicle dynamics control of a scale RC vehicle (2015)

This paper addresses the design, implementation and validation of a coordinated lateral and longitudinal dynamics control for a racing four-wheel driven RC vehicle. The coordination is achieved hierarchically: a wheel slip control loop stabilizes the fastest longitudinal dynamics, so that the outer lateral dynamics control can rely on non-saturated tires. Designing a wheel slip controller on a scale model requires the estimation of the wheel slip using a reduced set of sensors. The issue of estimating the wheel slip on such a small vehicle is addressed using a complementary filter. The presence of the inner wheel slip control enables the use of a simple gain-scheduled yaw-rate controller to stabilize the yaw rate dynamics and make the yaw rate gain velocity independent. The combined longitudinal and lateral controller is experimentally tested, using both repeatable tests with precomputed inputs and human-in-the-loop tests. The experimental results indicate that the controller is able to extend the operating envelope of the vehicle yielding an easier to operate vehicle.
Noninvasive dosimetry and monitoring of TTT using spectral imaging (2006)

Transpupillary thermo therapy (TTT) is a slow (60 seconds) photothermal treatment of the fundus with a near-infrared (780-810nm) laser irradiating a large spot (0.5- 1. mm) on the retina. Due to high variability in ocular tissue properties and the lack of immediately observable outcome of the therapy, a real-time dosimetry is highly desirable. We found that fundus spectroscopy and spectrally-resolved imaging allow for non-invasive real-time monitoring and dosimetry of TTT. A 795nm laser was applied in rabbit eyes for 60 seconds using a 0.86mm retinal spot diameter. The fundus was illuminated with a broadband polarized light, and its reflectance spectra were measured in parallel and cross-polarizations. The fundus was also imaged in selected spectral domains. At irradiances that do not create ophthalmoscopically visible lesions the fundus reflectance increases at the wavelengths corresponding to absorption of the oxygenated blood indicating the reduced concentration of blood in the choroid. Vasoconstrictive response of the choroidal and retinal vasculature during TTT was also directly observed using spectrally-resolved imaging. At irradiances that produce ophthalmoscopically visible lesions a rapid reduction of the fundus reflectance was observed within the first 5-10 seconds of the exposure even when the visible lesions developed only by the end of the 60 second exposure. No visible lesions were produced where the laser was terminated after detection of the reduced scattering but prior to appearance of the enhanced scattering.
Mechanical Properties and Microstructure of Magnesium Alloys Composites Fabricated by Casting (2000)

SiC and Al 18 B 4 O 33 particle/whisker reinforced (AZ91D) magnesium alloy matrix composites were fabricated by the melt stirring and casting and the squeeze casting. Some composites were fabricated under the semi-solid conditions and extruded at high temperature in order to improve the mechanical properties. The strength and the aging hardness of the composites were investigated. The microstructure was observed in order to investigate the preparation conditions of the composite having salient mechanical properties. Specially, the interlace between the reinforcement and the matrix were observed minutely by high-resolution electron microscopy. The reactivity between the whisker and the matrix in the composite is low, The reinforcements in all composites distribute uniformly in the matrix. The density and the strength of the composite increases and the grain size in the matrix decrease by the extrusion.

Portable performance on asymmetric multicore processors (2016)

Static and dynamic power constraints are steering chip manufacturers to build single-ISA Asymmetric Multicore Processors (AMPs) with big and small cores. To deliver on their energy efficiency potential, schedulers must consider core sensitivity, load balance, and the critical path. Applying these criteria effectively is challenging especially for complex and non-scalable multithreaded applications. We demonstrate that runtimes for managed languages, which are now ubiquitous, provide a unique opportunity to abstract over AMP complexity and inform scheduling with rich semantics such as thread priorities, locks, and parallelism— information not directly available to the hardware, OS, or application. We present the WASH AMP scheduler, which (1) automatically identifies and accelerates critical threads in concurrent, but non-scalable applications; (2) respects thread priorities; (3) considers core availability and thread sensitivity; and (4) proportionally schedules threads on big and small cores to optimize performance and energy. We introduce new dynamic analyses that identify critical threads and classify applications as sequential, scalable, or non-scalable. Compared to prior work, WASH improves performance by 20% and energy by 9% or more on frequency-scaled AMP hardware (not simulation). Performance advantages grow to 27% when asymmetry increases. Performance advantages are robust to a complex multithreaded adversary independently scheduled by the OS. WASH effectively identifies and optimizes a wider class of workloads than prior work.
PMUHardware and Algorithms (2016)

Abstract Phasor measurement units (PMUs) are digital instruments that report the magnitude and phase of sinusoidal voltages and currents on an AC power system at a rate of 30/50/60 samples per second. Coupled with a precise time signal such as GPS (global positioning system) time pulses, the magnitude and phase information can be time tagged and communicated via the Internet, allowing the investigation of power system dynamics over a large geographical area. This chapter reviews the PMU specifications and algorithms to compute the magnitude and phase of a sinusoidal signal, hardware components, and testing methods.
Knowledge Graph Completion to Solve University Campus Issues (2020)

A number of urban challenges are encountered by modern societies. Governments, businesses and public bodies need to make statistical data widely available in order to tackle these challenges. Nonetheless, current literature and data are problematic; they have inaccuracies which lead to less effective methods of resolving these issues. This research aims to solve this challenge by thinking of a university campus as a microcosm of society, implementing a data integration schema, and combining data into a knowledge graph. Existing completion methods will then be applied and updated. Especially in regards to bicycle environment, our knowledge graph was tailored and evaluated in line with conventional methods, and secondly with our proposed derivative methods. Roughly 650 pieces of parking data, with various dates and times, was contrasted with each time's mean absolute error. Our approach accurately projected 54.5 more bicycles than the conventional method.
Multivariable control for air management system in fuel reforming Fuel Cell Vehicle (2007)

With the purpose of meeting the specifically restrictive requirements of fuel reforming Fuel Cell Vehicle, this paper brings into focus the issues of transient operation of Fuel Cell systems, and presents a multivariable control methodology for Fuel Cell Air Management System. Indeed, considering the highly non-linear and coupled behaviour of thermo-fluid equations, the penalizing sensors dynamics, and the uncertainty on model parameters, design and control of such a complex air system require robust control strategies, that will ensure multiple control objectives while remaining suitable for onboard integration. In a first step, a dynamic and non-linear model exhibiting the main dynamics of the considered air system - based on lumped parameter pneumatic models combined with semi-empirical actuators models - is briefly described. Then, a classical approach is followed to obtain a reduced model that balances model fidelity with model simplicity. In a second step, we deduce from our model-based design methodology a LQ control structure - based on a multivariable state feedback - that limits the deterioration of performances by compensating inherent couplings and sensors dynamics. The validity of this approach is compared to monovariable strategies in simulation environment, and checked on a dedicated air supply system test bench.
Development of “spin dice” — A Scalable Random Number Generator Based on Spin-Torque Switching (2019)

We have developed a random-number-generator (RNG) named “spin dice,” which employs the stochastic nature of spin-torque switching (STS) in a magnetic tunnel junction. The principle of the idea is that the switching probability first tuned around 0.5 is varied linearly with the applied current. After that, the switching results are converted into binary random numbers. We fabricated several types of “spin dice” by combining magnetic tunnel junctions and single-board microcomputer, and achieved generation speed of random numbers up to several hundred kbit/sec. Because STS is scalable and magnetic tunnel junctions have compatibility to semiconductor fabrication process, “spin dice” can be considered as a promising candidate for truly random-number-generator (TRNG) for security applications.

Abstract B84: HCI-2528 is a potent inhibitor of LSD1 with improved druglike characteristics. (2011)

Abstract Lysine Specific Demethylase 1 (LSD1/KDM1A) plays an important role in the regulation of histone methylation at lysine residues, and is currently being validated as an attractive therapeutic target for many diseases, particularly for multiple forms of cancer. Methylation of lysine residues on histones can signal transcriptional activation or repression depending on the specific residue involved. H3K4me2 is a transcription-activating chromatin mark at gene promoters, and demethylation of this mark by LSD1 is thought to prevent expression of tumor suppressor genes important in human cancer. In contrast, methylation of H3K9 is a repressive mark and LSD1 activity has been shown to upregulate tumor promoting pathways. Thus, LSD1 is emerging as an important target for the development of specific inhibitors as a new class of antitumor drugs. Several LSD1 inhibitors have been reported, but they have shown poor selectivity and/or pharmacological properties, making further exploration of LSD1 biology difficult. We previously reported the identification of CIT-0665, an LSD1 inhibitor identified through a virtual screening effort in our lab. Evaluation of the structure activity relationships of multiple analogs of our LSD1 inhibitor led to the identification of HCI-2528, which is more potent and exhibits improved drug like properties. Using a cell viability assay, a large panel of cancer cell lines was tested for sensitivity to HCI-2528. In addition to the well-documented sensitivity of breast cancer cell lines, we also found that Ewing's sarcoma cell lines are uniquely sensitive to LSD-1 inhibition. We are currently engaged in a bioinformatic effort to determine possible mechanisms of sensitivity from our studies, and performing xenograft studies in mice. In conclusion, HCI-2528 is a novel LSD1 inhibitor with activity in biochemical and cell-based assays. Citation Format: {Authors}. {Abstract title} [abstract].

Nonboolean Pattern Recognition Using Chains of Coupled CMOS Oscillators as Discriminant Circuits (2017)

Networks of weakly coupled oscillators are special cases of Hopfield networks and as such may be used in building physical systems capable of associative memory recall and pattern recognition. However, the existing architectures are not suitable for hardware implementation mainly due to the complexity of required couplings between the oscillators. In this paper, we propose an alternative way of using coupled oscillators in what we call “discriminant circuits” in analogy to the concept of “discriminant functions” in the field of artificial intelligence and machine learning. The main advantage of our system is in the simplicity of its architecture, which relies only on local couplings between adjacent oscillators. Using this architecture, we design a network of coupled CMOS oscillators as the core of a physical non-Boolean pattern recognition engine. The simplicity of the proposed circuit makes it readily implementable on any standard CMOS technology.

Magnetoelastic/piezoelectric laminated structures for tunable remote contactless magnetic sensing and energy harvesting (2009)

In this letter, we report a method for a tunable magnetic field sensor based on the magnetoelastic coupling properties of a magnetoelastic/piezoelectric laminated composite structure. The magnetically and elastically tunable, flexural resonant mode in the bimorph FeNi36% (invar)/polyvinylidene fluoride clamped bilayer has been investigated by Doppler laser spectroscopy. Here we demonstrate that this bimorph structure can be used for low-frequency contactless detection of magnetic field fluctuation and magnetic field monitoring.
Metallography and Biomimetics – Or New Surfaces Without Chemistry? (2021)

Abstract Fingerprints, a butterfly’s wings, or a lotus leaf: when it comes to surfaces, there is no such thing as coincidence in animated nature. Based on their surfaces, animals and plants control their wettability, their swimming resistance, their appearance, and much more. Evolution has optimized these surfaces and developed a microstructure that fits every need. It is all the more astonishing that, with regard to technical surfaces, man confines himself to random roughnesses or “smooth” surfaces. It is surely not a problem of a lack of incentives: structured surfaces have already provided evidence of optimizing friction and wear [1, 2, 3, 4], improving electrical contacts [5, 6], making implants biocompatible [7, 8], keeping away harmful bacteria [9], and much more. How come we continue counting on grinding, polishing, sandblasting, or etching? As so often, the problem can be found in economic cost effectiveness. It is possible to produce interesting structures such as those of the feather in Fig. 1. However, generating fine structures in the micro and nanometer range usually requires precise processing techniques. This is complex, time-consuming, and cannot readily be integrated into a manufacturing process. Things are different with Direct Laser Interference Patterning, DLIP) [10, 11]. This method makes use of the strong interference pattern of overlapped laser beams as a “stamp” to provide an entire surface area with dots, lines, or other patterns – in one shot. It thus saves time, allows for patterning speeds of up to 1 m 2 /min and does it without an elaborate pre- or post-treatment [10, 12]. The following article intends to outline how the method works, which structures can be generated, and how the complex multi-scale structures that nature developed over millions of years can be replicated in only one step.
On the legacy of cover crop-specific microbial footprints (2023)

Apart from improving the physical and chemical condition of arable soils, cover crops have the potential to boost and activate selected soil microbiota that could contribute to improved nutrient cycling and strengthened disease suppressiveness. However, a main crop can only benefit from cover crop-induced microbial shifts if these persist until the onset of the main growing season. Here, we map the persistence of microbiome changes by cover crops over time. We performed a field experiment on a sandy soil with ten different cover crop monocultures belonging to five plant families, one cover crop mixture and a fallow control. Cover crops were grown for 4.5 months under field conditions in 70-L bottomless containers in a random block design with eight replications. We studied the total (DNA-based) and the potentially active (RNA-based) microbial fractions at the onset of the main growing season, and just after the harvest of the main crop, potato (respectively 3.5 and 10 months after cover crop termination), through MiSeq sequencing. All cover crops tested induced shifts in the soil microbiome that lasted at least until the onset of the main growing season. Cover crop treatments gave rise to species and even cultivar-specific microbial footprints, and - although roughly the same trends were observed - DNA-based microbial shifts were not necessarily paralleled by similar changes at RNA level. We conclude that cover crops have the potential to act as handles to steer the soil microbiome in a way that is supportive of sustainable crop production.
