Causal Frequency-Specific Contributions of Frontal Spatiotemporal Patterns Induced by Non-Invasive Neurostimulation to Human Visual Performance (2013)

Neural oscillatory activity is known to play a crucial role in brain function. In the particular domain of visual perception, specific frequency bands in different brain regions and networks, from sensory areas to large-scale frontoparietal systems, have been associated with distinct aspects of visual behavior. Nonetheless, their contributions to human visual cognition remain to be causally demonstrated. We hereby used non-uniform (and thus non-frequency-specific) and uniform (frequency-specific) high-beta and gamma patterns of noninvasive neurostimulation over the right frontal eye field (FEF) to isolate the behavioral effects of oscillation frequency and provide causal evidence that distinct visual behavioral outcomes could be modulated by frequency-specific activity emerging from a single cortical region. In a visual detection task using near-threshold targets, high-beta frequency enhanced perceptual sensitivity ( d′ ) without changing response criterion (beta), whereas gamma frequency shifted response criterion but showed no effects on perceptual sensitivity. The lack of behavioral modulations by non-frequency-specific patterns demonstrates that these behavioral effects were specifically driven by burst frequency. We hypothesize that such frequency-coded behavioral impact of oscillatory activity may reflect a general brain mechanism to multiplex functions within the same neural substrate. Furthermore, pathological conditions involving impaired cerebral oscillations could potentially benefit in the near future from the use of neurostimulation to restore the characteristic oscillatory patterns of healthy systems.
The use of acetyl-CoA carboxylase activity and changes in wall composition as measures of embryogenesis in tissue cultures of oil palm (<i>Elaeis guineensis</i>) (1982)

With some lines of oil-palm tissue cultures embryogenesis occurs spontaneously within the callus grown on a medium containing 2.5 mg of 3-naphthylacetic acid/litre. One of the initial biochemical events that occurs just before the embryoid can be seen is the accumulation of fat droplets within the cells. This accumulation of lipid is correlated with an increase in acetyl-CoA carboxylase activity. The carboxylase is thus probably a rate-limiting step in fatty acid synthesis in these cells and can be used as a quantitative marker of somatic embryogenesis within the tissue. During the development of the embryoid tissue there is an increase in cell division and the differentiation of vascular cells with secondary thickened walls. These stages of the differentiation may be monitored by measuring the ratio of pectin synthesis (polygalacturonic acid formation) to hemicellulose synthesis (xylan formation).
The interaction between polymer and surfactant as revealed by interfacial tension (2007)

The aging of aqeusous ethyl(hydroxyethyl)cellulose (EHEC) solution and mixed solutions of polymer and sodium dodecyl sufate (SDS) in contact with cyclohexane was studied by measurement of interfacial tension, using the pendant drop method. Studies were performed over the concentration ranges 0–18 mM SDS with fixed concentration 0.2% w/w EHEC, and 0–16 mM SDS with no polymer added. EHEC was found t be very surface active, and the kinetics of polymer adsorption to the water/cyclohexane interface is extremely slow. The mixed solutions of polymer and surfactant showed a more typical timescale for adsorption. The variation in the equilibrium interfacial tension of the mixed polymer-surfactant solutions was assumed to reflect the variation of the activity of polymer, and the interactions between the polymer and other particles in the system. The observed effects were explained as due to the changes in polymer-solvent and polymer-surfactant interactions, resulting in a changed conformation of the polymer, as well as the formation of micelle-like clusters and free micelles.

Oriented to Multi-Branched Structure Unsupported 3D Printing Method Research (2020)

For the traditional three-axis (3D) configuration of the additive manufacturing (AM) platform, when printing the target model with a multi-branched structure, it is imperative to construct adequate support structures. To eliminate the use of support during the printing process, a non-directional unsupported 3D printing method for five-axis AM is proposed in this paper. By carrying out the K-means clustering algorithm, the coarse partition of the model is obtained, and then the fine decomposition represented by a sequence of separating planes is determined by a local dynamic search adjustment algorithm according to manufacturing constraints. The multi-branched structure of the model is divided into simple subparts so that the general model can be built in different directions and be printed with its own parts as the support. Two case studies were carried out for verification. The experimental results showed that the branch-model can be printed without support using the non-directional unsupported 3D printing method, and the non-directional unsupported 3D printing can save 18.72-20.60% of materials and 20.60-23.33% of time compared to conventional 3D printing.
Detection and Recognition of Abnormal Running Behavior in Surveillance Video (2012)

Abnormal running behavior frequently happen in robbery cases and other criminal cases. In order to identity these abnormal behaviors a method to detect and recognize abnormal running behavior, is presented based on spatiotemporal parameters. Meanwhile, to obtain more accurate spatiotemporal parameters and improve the real‐time performance of the algorithm, a multitarget tracking algorithm, based on the intersection area among the minimum enclosing rectangle of the moving objects, is presented. The algorithm can judge and exclude effectively the intersection of multitarget and the interference, which makes the tracking algorithm more accurate and of better robustness. Experimental results show that the combination of these two algorithms can detect and recognize effectively the abnormal running behavior in surveillance videos.

Case report: fourth branchial pouch sinus. (1993)

The fourth branchial pouch sinus is a rare anomaly of the branchial arch apparatus. The 31st reported case of a fourth branchial sinus is presented. A thorough understanding of the developmental anatomy of the branchial region is necessary for the detection and treatment of this entity. The diagnosis can be made with a high index of suspicion in patients with recurrent left neck infections by demonstration of a pyriform sinus tract on pharyngoesophagram. Treatment consists of complete surgical excision following exposure of the entire course of the sinus tract including its insertion into the apex of the pyriform sinus.
A low-ripple poly-Si TFT charge pump for driver-integrated LCD panel (2005)

A low-ripple charge pump for voltage up-conversion is described which was implemented in a poly-Si thin-film-transistor (TFT) technology for driver-integrated liquid-crystal-display (LCD) panels. The ripple voltage of the charge pump is reduced by employing a multi-phase clocking method. The charge pump was implemented in a poly-Si TFT technology. For output current of 100/spl mu/A, filtering capacitor of 100 pF and pumping clock frequency of 1 MHz, the measured ripple voltage of the proposed charge pump is 135 mV while that of conventional Dickson charge pump is 590 mV. The measured pumping efficiencies of the Dickson and proposed 4-phase clocking charge pump are 59% and 65%, respectively.

New antibacterial agents are urgently needed for the elimination of biofilm-forming bacteria that are highly resistant to traditional antimicrobial agents. Proliferation of such bacteria can lead to significant economic losses in the agri-food sector. This study demonstrates the potential of the bacteriophage-derived peptidase, CHAP(K), as a biocidal agent for the rapid disruption of biofilm-forming staphylococci, commonly associated with bovine mastitis. Purified CHAP(K) applied to biofilms of Staphylococcus aureus DPC5246 completely eliminated the staphylococcal biofilms within 4 h. In addition, CHAP(K) was able to prevent biofilm formation by this strain. The CHAP(K) lysin also reduced S. aureus in a skin decolonization model. Our data demonstrates the potential of CHAP(K) as a biocidal agent for prevention and treatment of biofilm-associated staphylococcal infections or as a decontaminating agent in the food and healthcare sectors.
Analysis and Digital Realization of a Pseudorandom Gaussian and Impulsive Noise Source (1975)

This paper presents results on the analysis and digital hardware realization of a non-Gaussian impulse noise source which can be used to model the impulsive noise present in wide-band communications systems. The impulse noise appearing in practical systems is characterized by bursts of much higher amplitudes than would be predicted by a normal- or Gaussian-distribution law. A need exists for a better characterization of this non-Gaussian impulsive noise as well as actual noise generators which can be used for evaluation of present and future communications equipment under realistic system-operating conditions. The impulse noise model and the realization of the noise generator described in this paper are capable of producing Gaussian background noise, lognormal impulsive noise, and burst timing to set prescribed starting and ending times of the bursts and impulse density within each of the burst periods. The techniques used in this paper are based on first generating a basic pseudorandom binary sequence (PRBS) and then from this deriving the Gaussian background noise by adding samples from the PRBS generator. The lognormal noise is then derived from the same sequence by using an incremental exponential generator. The burst timing signals which realize an approximate Poisson distribution are obtained by observing the occurrences of specific subsequences from the PRBS generator.

Provable Inductive Matrix Completion (2013)

Consider a movie recommendation system where apart from the ratings information, side information such as user's age or movie's genre is also available. Unlike standard matrix completion, in this setting one should be able to predict inductively on new users/movies. In this paper, we study the problem of inductive matrix completion in the exact recovery setting. That is, we assume that the ratings matrix is generated by applying feature vectors to a low-rank matrix and the goal is to recover back the underlying matrix. Furthermore, we generalize the problem to that of low-rank matrix estimation using rank-1 measurements. We study this generic problem and provide conditions that the set of measurements should satisfy so that the alternating minimization method (which otherwise is a non-convex method with no convergence guarantees) is able to recover back the {\em exact} underlying low-rank matrix. In addition to inductive matrix completion, we show that two other low-rank estimation problems can be studied in our framework: a) general low-rank matrix sensing using rank-1 measurements, and b) multi-label regression with missing labels. For both the problems, we provide novel and interesting bounds on the number of measurements required by alternating minimization to provably converges to the {\em exact} low-rank matrix. In particular, our analysis for the general low rank matrix sensing problem significantly improves the required storage and computational cost than that required by the RIP-based matrix sensing methods \cite{RechtFP2007}. Finally, we provide empirical validation of our approach and demonstrate that alternating minimization is able to recover the true matrix for the above mentioned problems using a small number of measurements.
Gas phase diffusion and surface reactions in the chemical vapour deposition of silicon (1978)

Abstract In semiconductor technology silicon is widely used as a starting material for the production of a great number of devices ranging from complicated integrated circuits to cheap solar cells. In this technology the chemical vapour deposition (CVD) of silicon plays the important role of providing the thin silicon layer in which the active devices are formed. In the growth of silicon from the vapour phase the main methods used are the hydrogen reduction of silicon halides such as SiCl 4 or SiHCl 3 , or the decomposition of SiHl 4 . Various resistances are present to limit the growth rate, such as gas phase diffusion of reactants towards the interface and the surface reactions needed to arrive at the desired crystal structure. This paper deals with the nucleation of silicon, with models for high- and low temperature growth reactions and with the morphology of the resulting layers and the conditions are discussed under which monocrystalline, polycrystalline or amorphous layers can be expected.
Remote Sensing of Turbulence and Transverse Atmospheric Wind Profiles using Optical Reference Sources (1992)

This thesis examines a remote sensing technique for measuring the atmospheric structure constant and the transverse atmospheric wind velocity as a function of altitude by performing temporal and spatial correlations of band pass filtered wave front slope sensor measurements. Two point sources are used to illuminate two pairs-of cc>-located wave front slope sensors. The sources and sensors are arranged to give rise to crossed optical paths. For each pair of wave front slope sensors, the output of the larger sensor is subtracted from the output of the smaller sensor. This band pass filters the smaller sensor's output. The filtered outputs are then correlated. The spatial correlation is related to the structure constant by an integral containing a path weighting function. The path weighting function is sharply peaked at the intersection altitude and decays rapidly to zero. The temporal correlation is related to the wind velocity through an integral containing a wind path weighting function which is sharply peaked at the intersection altitude and decays rapidly to zero. The vertical resolution of each path weighting function is calculated. Also, signal-to-noise ratios are calculated using generally accepted models for the structure constant and atmospheric wind profiles.
A New Feature Ensemble with a Multistage Classification Scheme for Breast Cancer Diagnosis (2017)

A new and effective feature ensemble with a multistage classification is proposed to be implemented in a computer-aided diagnosis (CAD) system for breast cancer diagnosis. A publicly available mammogram image dataset collected during the Image Retrieval in Medical Applications (IRMA) project is utilized to verify the suggested feature ensemble and multistage classification. In achieving the CAD system, feature extraction is performed on the mammogram region of interest (ROI) images which are preprocessed by applying a histogram equalization followed by a nonlocal means filtering. The proposed feature ensemble is formed by concatenating the local configuration pattern-based, statistical, and frequency domain features. The classification process of these features is implemented in three cases: a one-stage study, a two-stage study, and a three-stage study. Eight well-known classifiers are used in all cases of this multistage classification scheme. Additionally, the results of the classifiers that provide the top three performances are combined via a majority voting technique to improve the recognition accuracy on both two- and three-stage studies. A maximum of 85.47%, 88.79%, and 93.52% classification accuracies are attained by the one-, two-, and three-stage studies, respectively. The proposed multistage classification scheme is more effective than the single-stage classification for breast cancer diagnosis.
Protein Sequences from Mastodon and <i>Tyrannosaurus Rex</i> Revealed by Mass Spectrometry (2007)

Fossilized bones from extinct taxa harbor the potential for obtaining protein or DNA sequences that could reveal evolutionary links to extant species. We used mass spectrometry to obtain protein sequences from bones of a 160,000- to 600,000-year-old extinct mastodon (Mammut americanum) and a 68-million-year-old dinosaur (Tyrannosaurus rex). The presence of T. rex sequences indicates that their peptide bonds were remarkably stable. Mass spectrometry can thus be used to determine unique sequences from ancient organisms from peptide fragmentation patterns, a valuable tool to study the evolution and adaptation of ancient taxa from which genomic sequences are unlikely to be obtained.
Characterization of NERF, a Novel Transcription Factor Related to the Ets Factor ELF-1 (1996)

We have cloned the gene for a novel Ets-related transcription factor, new Ets-related factor (NERF), from human spleen, fetal liver, and brain. Comparison of the deduced amino acid sequence of NERF with those of other members of the Ets family reveals that the level of homology to ELF-1, which is involved in the regulation of several T- and B-cell-specific genes, is highest. Homologies are clustered in the putative DNA binding domain in the middle of the protein, a basic domain just upstream of this domain, and several shorter stretches of homology towards the amino terminus. The presence of two predominant NERF transcripts in various fetal and adult human tissues is due to at least three alternative splice products, NERF-1a, NERF-1b, and NERF-2, which differ in their amino termini and their expression in different tissues. Only NERF-2 and ELF-1, and not NERF-1a and NERF-1b, function as transcriptional activators of the lyn and blk gene promoters, although all isoforms of NERF bind with affinities similar to those of ELF-1 to a variety of Ets binding sites in, among others, the blk, lck, lyn, mb-1, and immunoglobulin H genes and are expressed at similar levels. Since NERF and ELF-1 are coexpressed in B and T cells, both might be involved in the regulation of the same genes.
