A New Oriented-Diffusion Image Inpainting Framework for Striped Texture Images (2009)

Modeling texture image is a challenge in image processing. The classical PDE model proposed for digital image inpainting can not be directly applied to striped texture image inpainting, since variation analysis of the PDE model shows that it may lead to trivial solution. In this paper, A novel PDE framework is proposed for striped texture image inpainting. The major idea is to employ the orientation field to act as the constraint of the diffusion directions. Once the orientation field can be correctly estimated, the gray level information can be propagated into the inpainting domain along a local fix orientation, which characterizes the orientation of the stripes. This paper is also an attempt to proposing an inpainting model which explicitly encoding spatial or geometrical correlations which mean orientation field in our models, especially for striped texture image or texture image with similar patterns. Numerical experimental results show that the proposed models are superior to common PDE models when inpainting striped texture images.
Energy partition at the collapse of spherical cavitation bubbles (2012)

Spherically collapsing cavitation bubbles produce a shock wave followed by a rebound bubble. Here we present a systematic investigation of the energy partition between the rebound and the shock. Highly spherical cavitation bubbles are produced in microgravity, which suppresses the buoyant pressure gradient that otherwise deteriorates the sphericity of the bubbles. We measure the radius of the rebound bubble and estimate the shock energy as a function of the initial bubble radius (2-5.6mm) and the liquid pressure (10-80kPa). Those measurements uncover a systematic pressure dependence of the energy partition between rebound and shock. We demonstrate that these observations agree with a physical model relying on a first-order approximation of the liquid compressibility and an adiabatic treatment of the noncondensable gas inside the bubble. Using this model we find that the energy partition between rebound and shock is dictated by a single nondimensional parameter ξ=Δpγ6/[p(g0)1/γ(ρc2)1-1/γ], where Δp=p∞ - pv is the driving pressure, p∞ is the static pressure in the liquid, pv is the vapor pressure, pg0 is the pressure of the noncondensable gas at the maximal bubble radius, γ is the adiabatic index of the noncondensable gas, ρ is the liquid density, and c is the speed of sound in the liquid.

Development of a Low Cost Printable Chipless RFID Humidity Sensor (2013)

A novel low-cost chipless radio frequency identification tag sensor is presented. The tag sensor provides identification data as well as monitors relative humidity (RH) of tagged objects. The tag sensor is made of passive microwave circuit that uses humidity sensitive polymer material for RH sensing. The aim of this paper is to investigate RF sensing properties of moisture absorbing polymer polyvinyl alcohol at microwave frequency. In addition, frequency shifting technique is used to encode data bits for high data capacity. The overall size of the proposed tag sensor is 15 mm × 6.8 mm and has 6 bit data capacity for ID generation and single bit for humidity sensing. Results presented here show ~ 607 MHz frequency deviation for 50% RH increase. The tag sensor has potential to be printed on flexible laminates such as plastic and paper for ultra-low cost item level tagging and ubiquitous sensing.
Background Music Removal Based on Cepstrum Transformation for Popular Singer Identification (2010)

One major challenge of identifying singers in popular music recordings lies in how to reduce the interference of background accompaniment in trying to characterize the singer voice. Although a number of studies on automatic Singer IDentification (SID) from acoustic features have been reported, most systems to date, however, do not explicitly deal with the background accompaniment. This study proposes a background accompaniment removal approach for SID by exploiting the underlying relationships between solo singing voices and their accompanied versions in cepstrum. The relationships are characterized by a transformation estimated using a large set of accompanied singing generated by manually mixing solo singing with the accompaniments extracted from Karaoke VCDs. Such a transformation reflects the cepstrum variations of a singing voice before and after it is added with accompaniments. When an unknown accompanied voice is presented to our system, the transformation is performed to convert the cepstrum of the accompanied voice into a solo-voice-like one. Our experiments show that such a background removal approach improves the SID accuracy significantly; even when a test music recording involves sung language not covered in the data for estimating the transformation.

Evaluating Shear Rigidity of Woven Fabrics (2006)

A new shear tester of woven fabrics based on the trellis shear model is described. The tester can be used to carry out shear deformation experiments under quite low tensile stresses. The values of shear rigidity tested on the new tester were compared with those tested on the uniaxial tensile tester and the KES (Kawabata’s Evaluation System) instrument. The results confirm that the tester is more feasible and effective for measuring shear behavior in a natural state. This study establishes a foundation for constructing a universal instrument that can be used to measure shear deformation under any conditions.

The canthal regions can be successfully reconstructed with orbicularis oculi myocutaneous island flaps. These flaps offer several key advantages, including similarity in texture, color, and thickness to the recipient site and a negligible incidence of donor site morbidity.
Large-scale deployment of SIT-based technology in a Brazilian city prevented Dengue outbreak (2022)

Abstract Background Dengue is a global problem that seems to be worsening, as hyper-urbanization associated with climate change has led to a significant increase in the abundance and geographical spread of its principal vector, the Ae des aegypti mosquito. The current available solutions, including vaccines and traditional vector-control methods, have not been able to stop the spread of dengue which shows the urgent need to implement alternative technologies as practical solutions. We recently presented ‘Natural Vector Control’ (NVC), a new Sterile Insect Technology-based method that uses massive releases of sterile male mosquitoes produced from the combined treatment with dsRNA and thiotepa. In a previous pilot trial, two intervention periods over two epidemiological seasons were carried out, in which the control and treated areas were alternated between the epidemiological seasons, and we demonstrated the efficacy and safety of the method in suppressing the Ae. aegypti vector population and in blocking the occurrence of an outbreak of dengue in the treated areas. Here, we expand the use of the “Natural Vector Control” program in a large-scale 2-year period intervention carried out in an entire city located in southern Brazil. Methods Sterile male mosquitoes were produced from locally sourced Ae. aegypti mosquitoes by using a treatment that includes double-stranded RNA and thiotepa. Weekly massive releases of sterile male mosquitoes were performed in predefined areas of Ortigueira from December 2020 to July 2022. Mosquito monitoring was performed by using ovitraps during the entire period of intervention. Dengue incidence data in Ortigueira and neighboring cities was obtained from the Brazilian National Disease Surveillance system. Results During the two epidemiological seasons, the intervention in Ortigueira resulted in up to 98.7% suppression of live progeny of field Ae. aegypti mosquitoes recorded over time. More importantly, the program protected Ortigueira from a dengue outbreak that occurred in the neighboring cities: the dengue incidence in Ortigueira was 97% lower compared to 4 control cities. Conclusions The Natural Vector Control method has again been shown to be a safe and efficient way to suppress Ae. aegypti field populations and prevent the occurrence of a dengue outbreak. Importantly, it has been shown to be applicable for large-scale, real-life conditions.
Information-Energy Region for SWIPT Networks in Mobility Scenarios (2020)

This paper studies the information-energy (I-E) region for simultaneous wireless information and power transfer (SWIPT) networks in mobility scenarios, where a moving transmitter simultaneously transmits information and power to a fixed receiver, and the receiver adopts power splitting (PS) receiving architecture. In order to characterize the tradeoff between the received information and harvested energy, the I-E region is defined, and corresponding optimization problems are formulated to explore the system I-E regions by jointly optimizing the transmit power at the transmitter and the PS ratio at the receiver with three popular energy harvesting (EH) models, i.e., traditional linear EH model, the logistic nonlinear EH model and the piecewise nonlinear EH model. Particularly, to efficiently solve the nonconvex optimization problem with the logistic nonlinear EH model, a successive convex approximate (SCA)-based algorithm is proposed, which is able to characterize the lower bound of the I-E with low complexity. To solve the optimization problems with the linear and piecewise EH models, as they are convex, some closed and semi-closed solutions are derived by using Lagrange dual method and KKT conditions. Numerical results show that compared with the I-E regions under the linear and piecewise EH models, that under the logistic nonlinear EH model is smaller due to the limitations of practical EH circuit features. Moreover, with a fixed moving speed, when the transmit power is relatively large, the logistic nonlinear EH model can be replaced with the piecewise one due to the relatively small gap between their achieved I-E regions. Additionally, for a fixed moving track length, the higher moving speed yields the smaller I-E region with all three EH models.

Optimizing the Energy Efficiency of Unreliable Memories for Quantized Kalman Filtering (2022)

This paper presents a quantized Kalman filter implemented using unreliable memories. We consider that both the quantization and the unreliable memories introduce errors in the computations, and we develop an error propagation model that takes into account these two sources of errors. In addition to providing updated Kalman filter equations, the proposed error model accurately predicts the covariance of the estimation error and gives a relation between the performance of the filter and its energy consumption, depending on the noise level in the memories. Then, since memories are responsible for a large part of the energy consumption of embedded systems, optimization methods are introduced to minimize the memory energy consumption under the desired estimation performance of the filter. The first method computes the optimal energy levels allocated to each memory bank individually, and the second one optimizes the energy allocation per groups of memory banks. Simulations show a close match between the theoretical analysis and experimental results. Furthermore, they demonstrate an important reduction in energy consumption of more than 50%.

An Efficient Electroporation Protocol for the Genetic Modification of Mammalian Cells (2017)

Genetic modification of cell lines and primary cells is an expensive and cumbersome approach, often involving the use of viral vectors. Electroporation using square-wave generating devices, like Lonza's Nucleofector, is a widely used option, but the costs associated with the acquisition of electroporation kits and the transient transgene expression might hamper the utility of this methodology. In the present work, we show that our in-house developed buffers, termed Chicabuffers, can be efficiently used to electroporate cell lines and primary cells from murine and human origin. Using the Nucleofector II device, we electroporated 14 different cell lines and also primary cells, like mesenchymal stem cells and cord blood CD34+, providing optimized protocols for each of them. Moreover, when combined with sleeping beauty-based transposon system, long-term transgene expression could be achieved in all types of cells tested. Transgene expression was stable and did not interfere with CD34+ differentiation to committed progenitors. We also show that these buffers can be used in CRISPR-mediated editing of <i>PDCD1</i> gene locus in 293T and human peripheral blood mononuclear cells. The optimized protocols reported in this study provide a suitable and cost-effective platform for the genetic modification of cells, facilitating the widespread adoption of this technology.
CuI/Oxalamide Catalyzed Couplings of (Hetero)aryl Chlorides and Phenols for Diaryl Ether Formation (2016)

Couplings between (hetero)aryl chlorides and phenols can be effectively promoted by CuI in combination with an N-aryl-N'-alkyl-substituted oxalamide ligand to proceed smoothly at 120 °C. For this process, N-aryl-N'-alkyl-substituted oxalamides are more effective ligands than bis(N-aryl)-substituted oxalamides. A wide range of electron-rich and electron-poor aryl and heteroaryl chlorides gave the corresponding coupling products in good yields. Satisfactory conversions were achieved with electron-rich phenols as well as a limited range of electron-poor phenols. Catalyst and ligand loadings as low as 1.5 mol % are sufficient for the scaled-up variants of some of these reactions.
Preparation and Characterization of Single-Atom Tips (2004)

A new, simple, and easily reproducible method of preparing single-atom tips by electroplating Pd or Pt on single-crystal W(111) tips followed by thermal annealing in a vacuum is reported. These tips are both thermally and chemically stable and can also be regenerated when accidentally damaged. The atomic structures of the tips are identical to those prepared by vacuum evaporation, as observed by field ion microscopy. The corresponding field emission characteristics are investigated with field emission microscopy.
Criteria for the Detection of Hail Cells (1979)

One of the Soviet seeding criteria used to detect hail cells at an early stage of development is examined. The radar history of 195 strong convective cells is studied and compared with information of a dense hailpad network (323 pads per 1292 km2). It is found that all hail-bearing cells are detected early in their development. About 50% of the 71 cells which met the seeding criterion never produced hail on the ground. This corresponds to a 30% waste of seeding rockets. The criterion which uses six radar parameters can be replaced by a simpler and slightly more efficient criterion which necessitates only the determination of the height of the 45 dBZ contour H45 in relation to the melting level H0. The new criterion is compared with other criteria and its microphysical implications are discussed.
Self-contained, Integrated Biochip System for Sample-to- Answer Genetic Assays (2003)

Microfluidics-based biochip devices are developed to perform DNA analysis from complex biological sample solutions. Microfluidic mixers, valves, pumps, channels, chambers, heaters, and DNA microarray sensor are integrated to perform magnetic bead-based rare cell capture, cell preconcentration and purification, cell lysis, polymerase chain reaction, DNA hybridization and electrochemical detection in a single, fully automated biochip device. Pathogenic bacteria detection and singlenucleotide polymorphism analysis directly from blood are demonstrated. The device with capability of on-chip sample preparation and DNA detection provides a costeffective solution to direct sample-to-answer genetic analysis, and thus has potential impact in the fields of point-of-care genetic analysis and disease diagnosis.
Channel Identification: Secret Sharing using Reciprocity in Ultrawideband Channels (2007)

To establish a secure communications link between any two transceivers, the communicating parties require some shared secret, or key, with which to encrypt the message so that it cannot be understood by an enemy observer. Using the theory of reciprocity for antennas and electromagnetic propagation, a key distribution method is proposed that uses the ultrawideband channel pulse response between two transceivers as a source of common randomness that is not available to enemy observers in other locations. The maximum size of a key that can be shared in this way is characterized by the mutual information between the observations of two radios, and an approximation on mutual information is found for a general multipath channel and examples given for UWB channel models. Simulation results of key lengths achieved using the proposed key sharing techniques over some ultrawideband channel models are presented.
Integration of CFD to Design Experiments for Enhanced Spatial and Temporal Discretization (2017)

The availability of high fidelity Computational Fluid Dynamics (CFD) suitable for turbomachinery design offers a powerful tool to define an effective experimental measurement campaign. This paper describes approaches to integrate Reynolds-Averaged Navier-Stokes simulations into experiment design. CFD simulations are used to a priori estimate the measurement errors induced by the finite spatial sampling and inherent limited sensor bandwidth for space-resolved and time-resolved turbine aerothermal measurements. The CFD predictions are employed to optimize the probe placement and traversing while minimizing the measurement errors associated with the finite spatial sampling. Additionally, time-resolved CFD traces serve to quantify the measurement errors as a function of the measurement chain bandwidth. This approach was applied to a recent turbine test program, focused on the aerothermal characterization of the turbine over-tip casing endwall and downstream flow field. Based on the 3D simulations of the different rotor geometries, the discrete radial positions of the aerothermal probes located downstream of the stage were optimized to minimize the uncertainty on the individual aerodynamic quantities, as well as to mitigate the propagated uncertainty on the turbine loss coefficient. Furthermore, the effect of the implicit time-averaging of all sensors, due to the limited frequency response, was quantified. This manuscript illustrates the benefits of CFD in the design and planning of a turbine experimental campaign. Based on the proposed procedure, the experimentalist can find the best compromise between measurement precision and instrumentation costs by establishing the minimum sensor performance requirements to obtain the target accuracies.

It focuses on the dynamic simulations of carbene reaction. The chapter explores the general theme of organocatalysis by car-benes. It presents a short overview of the use of diaminocyclopropylidene. The chapter highlights the fact that organocatalysis by carbene is far from being restricted to N–heterocyclic carbenes (NHCs). It describes the oxidative homocoupling of pyridine-substituted NHC in the coordination sphere of copper. Diazoesters are still among the most relevant precursors of transition-metal car-benoids. Intermolecular NHC–catalysed reactions initiated by the umpolung of an aldehyde continue to be a powerful strategy for the construction of polycyclic skeletons. Computational methods have been used to investigate the formation and the chemical reactivity profile of various sulfonyl nitrenes. The chapter describes the flash vacuum thermolysis (FVT) chemistry and matrix photochemistry of diverse (hetero)aryl nitrenes.
