Nonlinear-periodical network traffic behavioral forecast based on seasonal neural network model (2004)

How to predict Internet behavior is a standing challenge to the study of network behavior. Traditionally, the ARIMA model, always used for network traffic prediction, has difficulties in deciding its parameter values and, therefore, finds it hard to deal with the condition of a nonlinear time series. The paper presents a seasonal neural network prediction model for monitoring network traffic based on the neural network model of a time series and the periodic trend of traffic behavior. In addition, a series of data processes are taken to improve the prediction accuracy. The result of the application of the model to CERNET traffic prediction shows the model's reasonableness, and that it is more accurate than the ARIMA model and the neural network common time series.
Chemoenzymatic Synthesis of New Brush Copolymers Comprising Poly(ω-pentadecalactone) with Unusual Thermal and Crystalline Properties (2004)

Lipases from different sources were screened to determine their relative performance to catalyze ω-pentadecalactone (PDL) ring-opening polymerization from the hydroxyl group of 2-hydroxyethyl methacrylate (2-HEMA) and ω-hydroxyl-ω‘-methacrylate−poly(ethylene glycol) [PEGMA (Mn 360)]. Novozym 435 was found to be the most active biocatalyst for 2-HEMA/PEGMA-initiated PDL ring-opening polymerizations at 70 °C for 48 h in toluene (1:2 w/v of monomers). Thus, 2-HEMA-terminated PPDL was synthesized in yields of ∼80% and with <2 mol % carboxyl-terminated PPDL from initiation by water. Similarly, PEGMA-terminated PPDL was prepared. The free radical polymerizations of the corresponding macromers were carried out with AIBN at 70 °C in toluene. Thermal analysis of 2-HEMA-co-b-PPDL and PEGMA-co-b-PPDL macromers showed them to be stable and highly crystalline (Tm from 80 to 90 °C). In PEGMA-co-b-PPDL macromers, X-ray diffraction measurements show that the ethylene oxide units of the PEG block crystallize in the PPDL lattice. The main change observed upon polymerization of the macromers is a decrease of crystallinity (by both DSC and X-ray measurements).
Graft Polymerisation of Functional Acrylic Monomers onto Cotton Fibres Activated by Continuous Ar Plasma (2005)

Abstract Summary: Continuous cold Ar plasmas were used to activate the mercerised cotton fabric towards surface‐initiated graft polymerisation of glycidyl methacrylate, 2‐hydroxyethyl methacrylate (HEMA) and 1,1,2,2‐tetrahydroperfluorodecyl methacrylate (XFDMA). Single and multi‐step processes, carried out either in the plasma chamber (one‐step and two‐step processes) or ex situ after plasma treatment, were explored to optimise the grafting efficiency. The mechanical properties of the grafted cotton were substantially unaffected. Grafting with XFDMA gave good results only when the plasma activation was performed on monomer‐impregnated fabrics, as shown by gravimetry, ATR FT‐IR spectroscopy, and water and oil repellence tests. On the contrary, with HEMA better results were obtained by in situ grafting from monomer vapours.

Amplification of the <i>neu/erbB-2</i> oncogene in a mouse model of mammary tumorigenesis (2000)

The neu (c-erbB-2, Her-2) protooncogene is amplified and overexpressed in 20-30% of human breast cancers. Although transgenic mouse models have illustrated the role of Neu in the induction of mammary tumors, Neu expression in these models is driven by a strong viral promoter of questionable relevance to the human disease. To ascertain whether expression of activated Neu under the control of the endogenous promoter in the mammary gland could induce mammary tumors we have generated mice that conditionally express activated Neu under the transcriptional control of the intact endogenous Neu promoter. Expression of oncogenic neu in the mammary gland resulted in accelerated lobulo-alveolar development and formation of focal mammary tumors after a long latency period. However, expression of activated Neu under the normal transcriptional control of the endogenous promoter was not sufficient for the initiation of mammary carcinogenesis. Strikingly, all mammary tumors bear amplified copies (2-22 copies) of the activated neu allele relative to the wild-type allele and express highly elevated levels of neu transcript and protein. Thus, like human erbB-2-positive breast tumors, mammary tumorigenesis in this mouse model requires the amplification and commensurate elevated expression of the neu gene.
Quantitative Microbiological Study of Human Carious Dentine by Culture and Real-Time PCR: Association of Anaerobes with Histopathological Changes in Chronic Pulpitis (2002)

The bacteria found in carious dentine were correlated with the tissue response of the dental pulps of 65 teeth extracted from patients with advanced caries and pulpitis. Standardized homogenates of carious dentine were plated onto selective and nonselective media under anaerobic and microaerophilic conditions. In addition, real-time PCR was used to quantify the recovery of anaerobic bacteria. Primers and fluorogenic probes were designed to detect the total anaerobic microbial load, the genera Prevotella and Fusobacterium, and the species Prevotella melaninogenica, Porphyromonas endodontalis, Porphyromonas gingivalis, and Micromonas (formerly Peptostreptococcus) micros. The pulpal pathology was categorized according to the cellular response and degenerative changes. Analysis of cultured bacteria showed a predominance of gram-positive microorganisms, particularly lactobacilli. Gram-negative bacteria were also present in significant numbers with Prevotella spp., the most numerous anaerobic group cultured. Real-time PCR analysis indicated a greater microbial load than that determined by colony counting. The total number of anaerobes detected was 41-fold greater by real-time PCR than by colony counting, while the numbers of Prevotella and Fusobacterium spp. detected were 82- and 2.4-fold greater by real-time PCR than by colony counting, respectively. Real-time PCR also identified M. micros, P. endodontalis, and P. gingivalis in 71, 60, and 52% of carious samples, respectively. Correlation matrices of the real-time PCR data revealed significant positive associations between M. micros and P. endodontalis detection and inflammatory degeneration of pulpal tissues. These anaerobes have been strongly implicated in endodontic infections that occur as sequelae to carious pulpitis. Accordingly, the data suggest that the presence of high levels of these bacteria in carious lesions may be indicative of irreversible pulpal pathology.
Automatic 3D face verification from range data (2003)

In this paper, we presented a novel approach for automatic 3D face verification from range data. The method consists of range data registration and comparison. There are two steps in registration procedure: the coarse step conducting the normalization by exploiting a priori knowledge of the human face and facial features, and the fine step aligning the input data with the model stored in the database by the partial directed Hausdorff distance. To speed up the registration, a simplified version of the model is generated for each model in the model database. During the face comparison, the partial Hausdorff distance is employed as the similarity metric. The experiments are carried out on a database with 30 individuals and the best EER of 3.24% is achieved.
Alginate‐encapsulated Human Hepatoblastoma Cells in an Extracorporeal Perfusion System Improve Some Systemic Parameters of Liver Failure in a Xenogeneic Model (2004)

Previous studies have demonstrated that alginate encapsulation of proliferating hepatocyte-derived cell lines (e.g., HepG2 cells) enhances the expression of differentiated hepatocyte function compared with conventional monolayer culture. Furthermore, such capsules have the advantage of cryopreservability, and can be readily manipulated, e.g., for the charging of extracorporeal devices. We utilize a rabbit model of acute liver failure caused by acetaminophen administration to rabbits pretreated to enhance cytochrome p450 enzyme activity, and demonstrate that encapsulated HepG2 cells, in an extracorporeal chamber, perfused by rabbit plasma separated on-line at a rate of 2-5 mL/min, and perfused over cells at 40-60 mL/min, improve systemic parameters of liver failure (diastolic blood pressure and transjugular venous oxygen saturation). Such encapsulated cells have the potential to be developed for extracorporeal liver support systems for acute liver failure.
Automatically classifying sentences in full-text biomedical articles into Introduction, Methods, Results and Discussion (2009)

Biomedical texts can be typically represented by four rhetorical categories: Introduction, Methods, Results and Discussion (IMRAD). Classifying sentences into these categories can benefit many other text-mining tasks. Although many studies have applied different approaches for automatically classifying sentences in MEDLINE abstracts into the IMRAD categories, few have explored the classification of sentences that appear in full-text biomedical articles. We first evaluated whether sentences in full-text biomedical articles could be reliably annotated into the IMRAD format and then explored different approaches for automatically classifying these sentences into the IMRAD categories. Our results show an overall annotation agreement of 82.14% with a Kappa score of 0.756. The best classification system is a multinomial naïve Bayes classifier trained on manually annotated data that achieved 91.95% accuracy and an average F-score of 91.55%, which is significantly higher than baseline systems. A web version of this system is available online at-http://wood.ims.uwm.edu/full_text_classifier/.
Inversion‐recovery echo‐planar imaging (ir‐epi) at 0.5 T (1990)

Echo-planar imaging is used in combination with a spin preparation phase to produce a T1-weighted image. The small additional time penalty in this procedure does not detract significantly from the ultrahigh-speed imaging capability of EPI, allowing a rapid real-time optimization of tissue parameters in the image display. Results obtained on a head demonstrate this technique.
Denucleation promotes neovascularization of ePTFE in vivo (1999)

Expanded polytetrafluoroethylene (ePTFE) implants are being increasingly used as vascular prostheses and other devices. However the tissue response associated with this and other polymer implants continues to limit any long-term function. One of the major approaches currently being investigated to improve biocompatibility involves surface modification of the base polymer. In this report, we attempted to alter the healing characteristics of ePTFE by denucleation, a process which removes air trapped within the interstices of the material. Additionally, adsorption of extracellular proteins on the denucleated polymer was also tested. After 5 weeks implanted in subcutaneous and epididymal fat sites of rats, the material was explanted and the healing around the implant evaluated histologically. We found that in skin implants, denucleation alone resulted in a substantial reduction in the fibrous capsule which has been previously reported for untreated ePTFE, and an increase in blood vessel development around and within the polymer. Absorption of extracellular matrix proteins prior to implantation resulted in a reduced vascularity of the implants compared with denucleation-only implants. Implants in fat tissue, regardless of treatment, showed very little tissue reaction, either in the number of inflammatory cells, development of a fibrous capsule or neovascularization. These results suggest that the presence of air nuclei within porous material may contribute to the inappropriate healing response associated with these polymers. In addition, they confirm earlier reports that healing around implanted polymers is tissue-specific.
RGB-Infrared Cross-Modality Person Re-Identification via Joint Pixel and Feature Alignment (2019)

RGB-Infrared (IR) person re-identification is an important and challenging task due to large cross-modality variations between RGB and IR images. Most conventional approaches aim to bridge the cross-modality gap with feature alignment by feature representation learning. Different from existing methods, in this paper, we propose a novel and end-to-end Alignment Generative Adversarial Network (AlignGAN) for the RGB-IR RE-ID task. The proposed model enjoys several merits. First, it can exploit pixel alignment and feature alignment jointly. To the best of our knowledge, this is the first work to model the two alignment strategies jointly for the RGB-IR RE-ID problem. Second, the proposed model consists of a pixel generator, a feature generator, and a joint discriminator. By playing a min-max game among the three components, our model is able to not only alleviate the cross-modality and intra-modality variations but also learn identity-consistent features. Extensive experimental results on two standard benchmarks demonstrate that the proposed model performs favorably against state-of-the-art methods. Especially, on SYSU-MM01 dataset, our model can achieve an absolute gain of 15.4% and 12.9% in terms of Rank-1 and mAP.
Using a Multi-Task Recurrent Neural Network With Attention Mechanisms to Predict Hospital Mortality of Patients (2019)

Estimating hospital mortality of patients is important in assisting clinicians to make decisions and hospital providers to allocate resources. This paper proposed a multi-task recurrent neural network with attention mechanisms to predict patients' hospital mortality, using reconstruction of patients' physiological time series as an auxiliary task. Experiments were conducted on a large public electronic health record database, i.e., MIMIC-III. Fifteen physiological measurements during the first 24 h of critical care were used to predict death before hospital discharge. Compared with the conventional simplified acute physiology score (SAPS-II), the proposed multi-task learning model achieved better sensitivity (0.503 ± 0.020 versus 0.365 ± 0.021), when predictions were made based on the same 24-h observation period. The multi-task learning model is recommended to be updated daily with at least a 6-h observation period, in order for it to perform similarly or better than the SAPS-II. In the future, the need for intervention can be considered as another task to further optimize the performance of the multi-task learning model.

Why Gases Dissolve in Liquids (1991)

The thermodynamics and statistical mechanics of solubility are fairly well understood. It is still very difficult, however, to make quantitative predictions of solubility for real systems from first principles. The purposes of this article are to present the results of solubility experiments in some prototype solute-solvent systems, to show how far they may be understood from molecular first principles, and to discuss some of the things that are still missing. The main systems used as examples have the inert gas xenon as solute and some simple organic liquids as solvents.

Synthesis of<u>N</u>-Aminopyrazinium Analogs of Cytidine and 2′-Deoxycytidine (1991)

Abstract N-Aminopyrazine analogues of cytidine and 2′-deoxycytidine were prepared from 1-(β-D-ribofuranosyl)-1,2-dihydro-2-oxopyrazine and 1-(2-deoxy-β-D-ribofuranosyl)-1,2-dihydro-2-oxopyrazine, respectively, by amination with O-mesitylenesulfonylhydroxylamine.
Novel method of producing ultrasmall platinum silicide gate electrodes (1985)

A novel method has been developed for producing platinum silicide gate electrodes with submicron width. A lateral chemical reaction of platinum with polycrystalline silicon at a step edge was used. The width of the wire is determined by the thickness of a sputtered metal layer. Wires with width between 35 and 300 nm have been produced. The method has been used for making long-channel field-effect transistors with good device properties. Some preliminary results of the study of the low-temperature electrical transport properties of inversion layers with width of 0.12 μm are reported.

A new positioning technique for RSS-Based localization based on a weighted least squares estimator (2008)

In this paper we propose the use of a weighted least squares estimator to calculate the position of a mobile node in RSS-based localization systems for ad hoc networks. This technique outperforms the traditional positioning algorithms in terms of localization accuracy and robustness to inaccuracy in the channel model. The performance of the method is shown both through numerical simulations and through some experiments with real data for a wireless sensor network and a WiFi network.
Visible light communication using laser diode based remote phosphor technique (2015)

This paper reports a demonstration of high speed visible light communications using a blue laser diode combined with a remote phosphor. This method both generates white light and supports multi Gb/s communications. Data rates of up to 5.62 Gb/s and 6.52 Gb/s were achieved by using OFDM with fixed-rate and adaptive loading approaches, respectively. A total data rate of 10 Gb/s was found to be achievable by employing a two channel imaging system. These results demonstrate the considerable promise of the laser diode based remote phosphor approach in visible light communications.
A model for n-well junction effect on gate-charging damage in PMOSFETs (2002)

A quantitative model explaining N-well junction effect on gate charging damage in PMOSFETs is presented. This model takes into account the reverse-biased N-well junction leakage, generated both thermally and by photons and its behavior on limiting charging current passing through gate oxide during plasma processing. The modeling results suggest that plasma illumination plays a key role in enabling gate charging damage in PMOSFETs. The model can also apply to reverse-biased source and drain junctions in both P and NMOSFETs during plasma events.
15.5 Cryo-CMOS circuits and systems for scalable quantum computing (2017)

Quantum computing holds the promise to achieve unprecedented computation power and to solve problems today intractable. State-of-the-art quantum processors consist of arrays of quantum bits (qubits) operating at a very low base temperature, typically a few tens of mK, as shown in Fig. 15.5.1 The qubit states degrade naturally after a certain time, upon loss of quantum coherence. For proper operation, an error-correcting loop must be implemented by a classical controller, which, in addition of handling execution of a quantum algorithm, reads the qubit state and performs the required corrections. However, while few qubits (~10) in today's quantum processors can be easily connected to a room-temperature controller, it appears extremely challenging, if not impossible, to manage the thousands of qubits required in practical quantum algorithms [1].
<i>Escherichia coli</i> SecY and SecE proteins appear insufficient to constitute the SecA receptor (1994)

In order to test whether SecY and SecE proteins constitute the SecA receptor inside out membrane vesicles where prepared from strains producing greatly different levels of these two proteins, and their SecA binding activity was quantitated. Substantial overproduction of SecE or SecY and SecE proteins resulted in no increase or only 50% increase, respectively, in the number of high affinity SecA binding sites. These results suggest that SecY and SecE proteins appear insufficient to constitute the primary SecA receptor. The existence of a cycle of SecA association with the inner membrane and its modulation by particular integral membrane proteins is discussed.
Increasing Herbicide Selectivity in Maize and Cowpeas by seed Treatment with Activated Carbon and NA (1976)

Abstract Treating maize seed and cowpea seed with activated carbon or naphthalic anhydride permitted highly selective and economic early control of grasses and some broadleaved weeds with respectively EPTC and linuron and EPTC and chloramben. Without protectant every herbicide treatment produced less crop yield than with protectant. Early season control of grasses with herbicides followed by one row-cultivation controlled weeds throughout the crop.
[Stomach tolerance of non-steroid anti-rheumatic agents. Studies on gastric irritation caused by carprofen in comparison with acetylsalicyclic acid, indomethacin, piroxicam, and diclofenac]. (1982)

This is the report of a study on the new non-steroidal antiphlogistic substance Carprofen. In this comparative study Carprofen was tested versus acetylsalicylic acid, Indomethacin, Piroxicam and Diclofenac using the gastric irritation model, by means of a non invasive technique of measuring the gastric transmural potential difference. The study was carried out on a group of 10 healthy male volunteers and led to the following results: The most marked irritation was observed after administration of acetylsalicylic acid followed by Indomethacin. The lowest values of the relevant parameters concerning the gastric irritation were measured after the administration of Carprofen. The differences between acetylsalicylic acid and Indomethacin, and between Indomethacin and the other nonsteroidal substances which were tested could be proven statistically. There was no difference between Piroxicam, Diclofenac and Carprofen that could be proven statistically, nevertheless Carprofen showed the lowest irritation potency of the three non-steroidal antiphlogistics tested.
