Micro electret power generators (2005)

The taming of electricity and its widespread use allows people to see in the dark, to speak to one another instantaneously across the earth, and it allows retrieval of data from instruments sent out of the solar system. It is right to expect that the uses and demand for electricity will continue to grow, and to extend the ability to generate electricity; here two new micromachined devices for converting mechanical energy into electrical energy are presented. Aided by the wealth of micromachining process technology, generators that use an oscillatory motion to modify the physical structure of a capacitor with a built-in electric field provided by a permanent electret have been designed, built, and tested. The electret creates an electric field inside the capacitor structure, which induces mirror charge at some potential. The modification of the capacitor then generates an alternating displacement current through an external circuit, which provides useful electrical power. The electret microphone is a similar well known device for converting pressure waves into electrical signals by varying the distance between two charged capacitive plates. This work explores and proves feasible the ability to use mechanical forces to change the overlapping area of a charged capacitor structure and using mechanical forces to move a liquid into the gap of a charged capacitor structure, changing its permittivity to produce electricity. This work demonstrates 2.5mW of power from a 2cm diameter rotary generator at 12kRPM and 10[micro]w for a 0.1cm3 linear shaking generator at 60Hz.
BRANCHED1 Interacts with FLOWERING LOCUS T to Repress the Floral Transition of the Axillary Meristems in Arabidopsis (2013)

Plant architecture shows a large degree of developmental plasticity. Some of the key determinants are the timing of the floral transition induced by a systemic flowering signal (florigen) and the branching pattern regulated by key factors such as BRANCHED1 (BRC1). Here, we report that BRC1 interacts with the florigen proteins FLOWERING LOCUS T (FT) and TWIN SISTER OF FT (TSF) but not with TERMINAL FLOWER1, a floral repressor. FT protein induced in leaves moves into the subtended bud, suggesting that FT protein also plays a role in promotion of the floral transition in the axillary meristem (AM). The brc1-2 mutant shows an earlier floral transition in the axillary shoots compared with the wild type, suggesting that BRC1 plays a role in delaying the floral transition of the AMs. Genetic and gene expression analyses suggest that BRC1 interferes with florigen (FT and TSF) function in the AMs. Consistent with this, BRC1 ectopically expressed in the shoot apical meristem delays the floral transition in the main shoot. These results taken together suggest that BRC1 protein interacts with FT and TSF proteins and modulates florigen activity in the axillary buds to prevent premature floral transition of the AMs.

Reconstructing Strings from Substrings (1995)

We consider an interactive approach to DNA sequencing by hybridization, where we are permitted to ask questions of the form "is s a substring of the unknown sequence S?", where s is a specific query string. We are not told where s occurs in S, nor how many times it occurs, just whether or not s a substring of S. Our goal is to determine the exact contents of S using as few queries as possible. Through interaction, far fewer queries are necessary than using conventional fixed sequencing by hybridization (SBH) sequencing chips. We provide tight bounds on the complexity of reconstructing unknown strings from substring queries. Our lower bound, which holds even for a stronger model that returns the number of occurrence of s as a substring of S, relies on interesting arguments based on de Bruijn sequences. We also demonstrate that subsequence queries are significantly more powerful than substring queries, matching the information theoretic lower bound. Finally, in certain applications, something may already be known about the unknown string, and hence it can be determined faster than an arbitrary string. We show that building an optimal decision tree is NP-complete, then give an approximation algorithm that gives trees within a constant multiplicative factor of optimal.
Optimizing pulsed OBIC technique for ESD defect localization (2006)

The evolution of laser sources has led to the advent of new laser-based techniques for failure analysis. The pulsed OBIC (optical beam induced current) technique is one of them, which is based on the photoelectric laser stimulation of the device under test (DUT) at a micrometric scale. The suitability of this technique to localize failure sites resulting from electrostatic discharges (ESD) has previously been demonstrated. This paper presents a complementary work on the OBIC experimental procedure for defect localization improving the sensitivity of this technique and thus the probability to localize very small size defects

Identification of wheat endosperm proteins by MALDI mass spectrometry and LC-MS/MS. (2002)

The commercial value of the wheat crop is a function of the quality and amount of the storage protein and starch present in the grain, which in turn are influenced by environmental conditions during grain-fill. To understand how environment modifies the size and composition of wheat grains, we set out to identify the key metabolic and regulatory proteins in developing grain. We present results of initial studies aimed at establishing instrument conditions that will allow us to identify cytoplasmic proteins present in wheat endosperm. Proteins were isolated, separated by 2D gel electrophoresis and stained with Coomassie blue to visualize and quantify changes in protein expression. Mass spectrometry was used to identify protein spots in 2D gels by means of "peptide mass maps" of in-gel enzymatically digested protein spots. Because only about 30% of the proteins could be identified by "peptide mass mapping," we developed nano-flow LC-MS/MS techniques that allowed us to identify about 80% of the salt-soluble proteins in wheat endosperm.
Near-Ultraviolet Mutagenesis in Superoxide Dismutase-deficient Strains of Escherichia coli. (1994)

We compared mutagenic spectra induced by polychromatic near-ultraviolet radiation (near-UV; 300-400 nm) with superoxide anion (O2-) -dependent mutagenesis using a set of Escherichia coli tester strains. Near-UV radiation produced increased frequencies of G:C to A:T transitions, G:C to T:A and A:T to T:A transversions, and small increases in frameshift mutations in wild-type cells. Tester strains lacking superoxide dismutase (SOD) activity (sodAsodB double mutants) demonstrated high spontaneous mutation frequencies and increased near-UV sensitivity. The double mutants also showed increased mutations induced by near-UV compared to either isogenic wild type, sodA or sodB single mutants. Furthermore, these mutants had an unusual spontaneous mutation spectrum, with a predominance of A:T to T:A transversions, followed by G:C to T:A transversions and frameshifts generated in runs of adenines in both the +1 and -1 direction. Other frameshifts were detected to a lesser degree. The oxygen dependency and the type of mutations spontaneously induced in SOD-deficient cells indicated that this mutagenic spectrum was caused by oxidative DNA damage. However, no apparent synergistic action between near-UV radiation and an increased flux of O2- could be detected. From the frequency and types of mutations induced by the two agents, we speculate that near-UV-induced mutagenesis and O2--dependent mutagenesis involve, in part, different lesion(s) and/or mechanism(s). The nature and possible mutagenic pathways of each are discussed.
Event-triggered control via reset control systems framework (2016)

This paper deals with a systematic way to design the event-triggered rules to stabilize a class of linear reset control systems. The event-triggering condition depends only on local information, that is it only uses the measured signals. The approach proposed combines a hybrid framework to describe the sampled-data system with Lyapunov-based techniques. Dwell-time dependent constructive conditions expressed through linear matrix inequalities (LMI) are proposed to design the event-triggered rule ensuring the asymptotic stability of the closed-loop system. The effectiveness of the approach is evaluated through an example borrowed from the literature.
Overexpression of c-erbB-2/neu in breast cancer cells confers increased resistance to Taxol via mdr-1-independent mechanisms. (1996)

It has been reported that breast tumors that overexpress c-erbB-2/neu are less responsive to certain adjuvant chemotherapy regimens than those that express a normal amount of the gene product. To investigate whether overexpression of the c-erbB-2/neu-encoded p185 can indeed lead to increased chemoresistance in breast cancers, we introduced the human c-erbB-2/neu gene into the very low p185-expressing MDA-MB435 human breast cancer cells and examined Taxol sensitivities among the parental MDA-MB-435 cells and stable transfectants which express increased levels of p185. The p185-overexpressing MDA-MB-435 transfectants were more resistant to Taxol than the parental cells. The increased Taxol resistance was not accompanied by changes in doubling time and S-phase fraction. The increased Taxol resistance was independent from oncogenic transformation since it was observed only in c-erbB-2/neu-transformed cells and not ras-transformed cells when oncogene-transformed NIH3T3 cells were examined. To study whether p185 induced Taxol resistance through the mdr-1 pathway, we examined the mdr-l-encoded p170 levels in these transfectants. The MDA-MB-435 cells expressed very low levels of p170 and there was no increase of p170 expression in the p185-overexpressing MDA-MB-435 transfectants. Furthermore, these transfectants were not sensitized to Taxol treatment by mdr-1 blocker thioradazine. These data demonstrated that overexpression of c-erbB-2/neu can lead to intrinsic Taxol resistance independent from mdr-1 mechanisms.

Efficient Modeling of the Lithium Ion Cell Using the Proper Orthogonal Decomposition Method (2010)

The lithium ion cell has been widely used in portable electronic devices, is used in aerospace and is the most promising power supplier for hybrid electric vehicles (HEV) and electric vehicles (EV) because of its high energy density, no memory effect, and low self-discharge properties. Since the lithium ion cell is gradually becoming an indispensable energy storage device in human life, the studies of mathematical modeling of the lithium ion cell have been extensively scrutinized to better understand the mechanism of the electrochemical process in the cell, to extend the cell life, and to prevent thermal runaway. Among the current models for the lithium ion cell, the physics based pseudo two-dimensional (P2D) model is commonly believed as the most accurate model, but it is also the most time consuming model. The proper orthogonal decomposition method was also applied to develop an efficient, reduced order electrochemical-thermal model for a lithium ion cell. This model was validated for discharge simulations over a wide range of C rates and various cooling conditions of the cell. The ROM agrees well with the simulation from COMSOL Multiphysics®, a commercial finite element method (FEM) solver, and requires about seven times less computation time than the COMSOL model. The model predictions indicate that the discharge time or percent of capacity removed from the cell at an end of discharge voltage of 3.0V depends on the rate of the discharge and heat transfer rate away from the cell. Also, the heat transfer rate determines whether the capacity removed is limited by mass transfer in the solid phase or mass transfer in the electrolyte. Accurately approximating the surface concentration in the solid particles plays important role to obtain accurate simulation results using the P2D model for a lithium ion cell in the applications with high rate charge/discharge. The frequency responses of the surface concentration for the various simplified models for the diffusion problem in the spherical particle were compared to the analytical solution. It was turned out that the current simplified models for the diffusion problem fail for the short time period when the frequency is greater than 10 rad/sec. The method of orthogonal collocation on finite elements was introduced to solve the diffusion problem numerically. The effects of the number of collocation points, the locations of the collocation points and the size of the element near the surface on the accuracy of the approximation of the surface concentration for the short time period were analyzed. The reduced order model for the diffusion problem was developed based on the method of the orthogonal collocation on finite elements and the proper orthogonal decomposition. The effects of the locations of the collocation points on the frequency response of the surface concentration predicted by the reduce order model were discussed.

Solvothermal treatment of MgF2 coating solutions: a comparative study (2022)

Abstract MgF 2 coating solutions were prepared by the fluorolytic processing of Mg(OEt) 2 and MgCl 2 . Parts of these sols are solvothermally treated in an autoclave at 160 °C. The two respective precursors were used to prepare porous λ/4 antireflective films by dip-coating on soda-lime and borosilicate glass substrates. UV–Vis spectroscopy and X-Ray diffraction (XRD) were applied to characterize the films as a function of annealing temperature. Samples treated at 500 °C underwent testing of abrasion resistance and water solubility.

Design of an efficient terahertz source using triply resonant nonlinear photonic crystal cavities (2009)

We propose a scheme for efficient cavity-enhanced nonlinear THz generation via difference-frequency generation (DFG) processes using a triply resonant system based on photonic crystal cavities. We show that high nonlinear overlap can be achieved by coupling a THz cavity to a doubly-resonant, dual-polarization near-infrared (e.g. telecom band) photonic-crystal nanobeam cavity, allowing the mixing of three mutually orthogonal fundamental cavity modes through a chi((2)) nonlinearity. We demonstrate through coupled-mode theory that complete depletion of the pump frequency - i.e., quantum-limited conversion - is possible. We show that the output power at the point of optimal total conversion efficiency is adjustable by varying the mode quality (Q) factors.

Should We Use the Sample? Analyzing Datasets Sampled from Twitter’s Stream API (2015)

Researchers have begun studying content obtained from microblogging services such as Twitter to address a variety of technological, social, and commercial research questions. The large number of Twitter users and even larger volume of tweets often make it impractical to collect and maintain a complete record of activity; therefore, most research and some commercial software applications rely on samples, often relatively small samples, of Twitter data. For the most part, sample sizes have been based on availability and practical considerations. Relatively little attention has been paid to how well these samples represent the underlying stream of Twitter data. To fill this gap, this article performs a comparative analysis on samples obtained from two of Twitter’s streaming APIs with a more complete Twitter dataset to gain an in-depth understanding of the nature of Twitter data samples and their potential for use in various data mining tasks.
Quantifying dysphonia severity using a spectral/cepstral-based acoustic index: Comparisons with auditory-perceptual judgements from the CAPE-V (2010)

This study investigated the relationship between acoustic spectral/cepstral measures and listener severity ratings in normal and disordered voice samples. CAPE-V sentence samples and the vowel /a/were elicited from eight normal speakers and 24 patients with varying degrees of dysphonia severity. Samples were analysed for measures of the cepstral peak prominence (CPP), the ratio of low-to-high spectral energy, and their respective standard deviations. Perceptual ratings of overall severity were also obtained for all samples. Results showed that all acoustic variables combined in a four-factor model which correlated with perceived severity with R = 0.81 (R(2) = 0.65). For the vowel /a/, a five-factor model incorporating all acoustic variables and gender correlated with perceived severity with R = 0.96 (R(2) = 0.91). Results indicate that a strong relationship between perceptual and acoustic estimates of dysphonia severity can be achieved in both continuous speech and vowel contexts using a model incorporating spectral/cepstral measures.

Mobility Control Experience in the Joffre Viking Miscible CO2 Flood (1993)

Summary This paper discusses mobility control in the Joffre Viking field miscible CO2 flood. Since 1984, three injection strategies have been tried: water-alternating-CO2 (WACO2), continuous CO2, and simultaneous CO2 and water. The studies showed that simultaneous injection results in the best CO2 conformance. CO2-foam injection has also been investigated.
Correlation Maximized Structural Similarity Loss for Semantic Segmentation (2019)

Most semantic segmentation models treat semantic segmentation as a pixel-wise classification task and use a pixel-wise classification error as their optimization criterions. However, the pixel-wise error ignores the strong dependencies among the pixels in an image, which limits the performance of the model. Several ways to incorporate the structure information of the objects have been investigated, \eg, conditional random fields (CRF), image structure priors based methods, and generative adversarial network (GAN). Nevertheless, these methods usually require extra model branches or additional memories, and some of them show limited improvements. In contrast, we propose a simple yet effective structural similarity loss (SSL) to encode the structure information of the objects, which only requires a few additional computational resources in the training phase. Inspired by the widely-used structural similarity (SSIM) index in image quality assessment, we use the linear correlation between two images to quantify their structural similarity. And the goal of the proposed SSL is to pay more attention to the positions, whose associated predictions lead to a low degree of linear correlation between two corresponding regions in the ground truth map and the predicted map. Thus the model can achieve a strong structural similarity between the two maps through minimizing the SSL over the whole map. The experimental results demonstrate that our method can achieve substantial and consistent improvements in performance on the PASCAL VOC 2012 and Cityscapes datasets. The code will be released soon.
