Channel State Information Prediction for 5G Wireless Communications: A Deep Learning Approach (2018)

Channel state information (CSI) estimation is one of the most fundamental problems in wireless communication systems. Various methods, so far, have been developed to conduct CSI estimation. However, they usually require high computational complexity, which makes them unsuitable for 5G wireless communications due to employing many new techniques (e.g., massive MIMO, OFDM, and millimeter-Wave (mmWave)). In this paper, we propose an efficient online CSI prediction scheme, called OCEAN, for predicting CSI from historical data in 5G wireless communication systems. Specifically, we first identify several important features affecting the CSI of a radio link and a data sample consists of the information of the features and the CSI. We then design a learning framework that is an integration of a CNN (convolutional neural network) and a long short term with memory (LSTM) network. We also further develop an offline-online two-step training mechanism, enabling the prediction results to be more stable when applying it to practical 5G wireless communication systems. To validate OCEAN's efficacy, we consider four typical case studies, and conduct extensive experiments in the four scenarios, i.e., two outdoor and two indoor scenarios. The experiment results show that OCEAN not only obtains the predicted CSI values very quickly but also achieves highly accurate CSI prediction with up to 2.650-3.457 percent average difference ratio (ADR) between the predicted and measured CSI.
Ionic Liquids with Low Melting Points and Their Application to Double-Layer Capacitor Electrolytes (2002)

Ionic liquids, 1-ethyl-3-methylimidazolium hexafluorotantalate and hexafluoroniobate were synthesized by a new method. They showed lower melting points and higher decomposition temperatures than popular due to larger anion size. Electrolytic conductivities of these ionic liquids were about 6 mS cm−1 at 25°C. Lowering the melting point of ionic liquids did not result in the improvement of low-temperature characteristics of carbon double-layer capacitors, however, the new ionic liquids showed long life compared with and at 3.0 V, 70°C. The derivatives of the new ionic liquids having a methyl group in 2-position (1-ethyl-2,3-dimethylimidazolium salts) were not ionic liquids at room temperature. © 2002 The Electrochemical Society.

High‐performance ester‐based two‐stroke engine oils (1991)

Abstract As lubricant classification of different types of two‐stroke oil moves towards realisation, the need has emerged for environmentally friendly two‐stroke lubricants suitable for different operating conditions and applications. In this paper the authors report results on ester‐based synthetic lubricants according to various test regimes, and show the superiority of synthetics in these tests. Outboard and chainsaw 2T lubricants are discussed.
Doppler compensation for underwater acoustic communications (2003)

Doppler shift in underwater acoustic communications presents a major challenge to modern designers. Carrier tracking and symbol synchronisation are severely affected by Doppler shift induced by relative motion of the transmitting and receiving structures. This paper presents an efficient Doppler compensation system that can be used as a generic pre-processor to conventional equalisation and beamforming structures. The rationale behind the choice of the design parameters is reported as well as the experimental system performance based on results from trials in the North Sea.
Short-block LDPC codes design with semi-random parity-check matrix (2013)

In this paper, we propose a design method for short block length low-density parity-check (LDPC) codes which use the structure of semi-random parity-check matrix and the optimal degree distribution pairs derived from density evolution algorithm. Simulation results show that the bit error performance of the designed code is better than Turbo codes with the same block length and code rate when Signal Noise Ratio (SNR) exceeds 2.5dB. At the same time, the complexity of decoder is lower than that of Turbo codes. This design method provides guiding significance for choosing an error-correcting code for reliable communication in narrow-band channel.
A SELECTIVE 1,2-REDUCTION OF γ-AMINO-α,β-UNSATURATED ESTERS BY MEANS OF BF3·OEt2-DIBAL-H SYSTEM. HIGHLY VERSATILE CHIRAL BUILDING BLOCKS FROM α-AMINO ACIDS (1986)

Abstract A combination of DIBAL-H with BF3·OEt2 has been demonstrated to be a promising agent for a selective 1,2-reduction of γ-amino-α,β-unsaturated esters, which, otherwise, is difficult to realize and provides the route to potent chiral building blocks from α-amino acids.
Formation of Photo-Luminescent Patterns on Paper Using Nanocrystalline Quantum Dot Ink and Mist Deposition (2013)

This study explores patterned deposition of cadmium selenide (CdSe) nanocrystalline quantum dot (NQD) thin films on paper substrates using the process of mist deposition. Because NQDs film can be engineered to produce unique emissive response, an application that prompted this research is concerned with printing of security/anti-counterfeiting patterns and identification labels on various substrates, including paper. Among other thin-film techniques using colloidal solution as a precursor, mist deposition is in this study predicted through Monte Carlo simulation and demonstrated through experiments to be particularly suitable for creating NQD micro-patterns on paper. In this experiment, barcode-like patterned NQD films were successfully deposited on various types of paper substrates. The films were characterized for fluorescence intensity, emission spectrum and quality of pattern transfer from shadow mask to the deposited film. Time dependent degradation of the deposited pattern was among key aspects investigated. The results obtained indicate that NQD films deposited on paper and encapsulated using plastic laminate did not show degradation in photoluminescence intensity over a period of nine weeks.

Reducing risks of widespread faults and attacks for commercial software applications: towards diversity of software components (2003)

Recent IT attacks demonstrated how vulnerable consumers and enterprises are when adopting commercial and widely deployed operating systems, software applications and solutions. Diversity in software applications is fundamental to increase chances of survivability to faults and attacks. Current approaches to diversity are mainly based on the development of multiple versions of the same software, their parallel execution and the usage of voting mechanisms. Because of the high cost, they are used mainly for very critical and special cases. We introduce and discuss an alternative method to ensure diversity for common widespread software applications without requiring additional resources. We describe a few encouraging results obtained from simulations.

Single Frequency Filtering Approach for Discriminating Speech and Nonspeech (2015)

In this paper, a signal processing approach is proposed for speech/nonspeech discrimination. The approach is based on single frequency filtering (SFF), where the amplitude envelope of the signal is obtained at each frequency with high temporal and spectral resolution. This high resolution property helps to exploit the resulting high signal-to-noise ratio (SNR) regions in time and frequency. The variance of the spectral information across frequency is higher for speech and lower for many types of noises. The mean and variance of the noise-compensated weighted envelopes are computed across frequency at each time instant. Decision logic is applied to the feature derived from the mean and variance values on varieties of degradations, including NTIMIT, CTIMIT and distance speech, besides degradation due to standard noise types. In all cases, the proposed method gives significantly better performance than the standard Adaptive Multi-rate VAD2 (AMR2) method. AMR2 method is chosen for comparison, as the method adapts itself for different degradations, and is seen to give good performance over different SNR situations. The proposed method does not use training data to derive the characteristics of speech or noise, nor makes any assumption on the nonspeech beginning. The SFF method appears promising in other applications of speech processing, such as pitch extraction and speech enhancement.
Ultrasonic wave propagation in thick, layered composites containing degraded interfaces (2005)

The ultrasonic wave propagation of thick, layered composites containing degraded bonds is investigated. A theoretical one-dimensional model of three attenuative viscoelastic layers containing two imperfect interfaces is introduced. Elastic material properties and measured values of ultrasonic phase velocity and attenuation are used to represent E-glass and vinyl ester resin fiber-reinforced plastic (FRP) laminate, syntactic foam, and resin putty materials in the model. The ultrasonic phase velocity in all three materials is shown to be essentially constant in the range of 1.0 to 5.0 megahertz (MHz). The attenuation in all three materials is constant or slightly increasing in the range 1.0 to 3.0 MHz. Numerical simulation of the model via the mass-spring-dashpot lattice model reveals the importance of the input signal shape, wave speed, and layer thickness on obtaining non-overlapping, distinct return signals in pulse-echo ultrasonic nondestructive evaluation. The effect of the interface contact quality on the reflection and transmission coefficients of degraded interfaces is observed in both the simulated and theoretical results.
Metric Structure of the Space of Two-Qubit Gates, Perfect Entanglers and Quantum Control (2013)

We derive expressions for the invariant length element and measure for the simple compact Lie group SU(4) in a coordinate system particularly suitable for treating entanglement in quantum information processing. Using this metric, we compute the invariant volume of the space of two-qubit perfect entanglers. We find that this volume corresponds to more than 84% of the total invariant volume of the space of two-qubit gates. This same metric is also used to determine the effective target sizes that selected gates will present in any quantum-control procedure designed to implement them.

Monolithically integrated InGaAlAs dielectric reflectors for vertical cavity optoelectronic devices (1991)

Monolithically integrated dielectric reflectors have opened up a new field of optoelectronic devices. Vertical cavity lasers in the AlGaAs system are grown by MBE almost as a matter of routine. In this contribution dielectric reflectors composed of InAlAs and InGaAlAs lattice matched to InP are investigated. We achieve reflectivities of 70%, 83%, and 96% using 5, 10, and 20 periods of quarter wavelength layers. Increasing the number to 30 periods results in a maximum reflectivity exceeding 99% at a center wavelength of 1.65 μm. These experimental results indicate that vertical cavity lasers for optical communication systems in the InGaAlAs system are feasible.
Handover of packet-switched services in GERAN A/Gb mode (2005)

Due to strict quality of service requirements on low latency and packet loss, real-time packet-switched (PS) services require a minimal service interruption on the data transfer during cell change. Existing GPRS cell change mechanisms with network assisted cell change (NACC) enable a theoretical minimum service interruption of 0.7-1.2 second, while real-time PS services of conversational class do not tolerate a service gap longer than 0.15 seconds. Therefore in GERAN A/Gb mode a PS handover procedure is being designed to allow for conversational services in GPRS that would improve the network performance for any PS service. PS handover follows the GSM circuit-switched handover principle of allocating radio resources in the target cell prior to changing cell. In this paper PS handover procedure is described and its performance evaluated in terms of service interruption by means of network simulations
Ti O 2 – Cd Se nanowire arrays showing visible-range light absorption (2007)

High-density single crystalline TiO2 nanowires (∼50nm diameter) were grown on Ti substrates by chemical vapor deposition, and they were overcoated with the solution containing CdSe nanocrystals (∼5nm diameter) and heat treated at 600°C to form TiO2 hetersotructured nanowire arrays. The TiO2 nanowire arrays showed uniformly distributed CdSe nanocrystals and high crystallinity of rutile and wurtzite from the TiO2 and the CdSe, respectively. Owing to the heterostructure of TiO2, they demonstrate almost full visible-range light absorption, and thus enhanced photocatalytic activity by the charge separation via electron and hole transfers between the CdSe and the TiO2.
Radiotherapy and concomitant chemoradiotherapy in the NB rat prostate adenocarcinoma model. (1992)

The NB Rat Prostate Adenocarcinoma Model has been utilized to evaluate the effect of radiation therapy, chemotherapy, and the combination of these two modalities on growth of the androgen insensitive Nb AI-3 prostate tumor. These studies have demonstrated tumor regression in animals treated with Cyclophosphamide in combination with Cisplatin (p less than 0.05). Tumor regression was also seen in the groups treated with radiation therapy at doses of 600 cGy, twice weekly, for three weeks (p less than 0.05), 500 cGy, three times weekly, for three weeks (p less than 0.05), and 300 cGy, three times weekly, for three weeks (p less than 0.05). Complete tumor regression was seen in groups receiving 500 cGy, three times per week, for three weeks, concomitantly with fractional dose Cyclophosphamide and Cisplatin (p less than 0.001). Complete tumor regression was also seen in rats treated with radiation therapy at a dose of 300 cGy three times per week for three weeks concomitantly with fractional dose Cyclophosphamide and Cisplatin (p less than 0.001). Another group treated with radiation therapy alone at a dose of 750 cGy, one time weekly, for four weeks, demonstrated progression of tumor growth. All control and treatment groups demonstrated metastatic lesions with the exception of the group receiving 600 cGy twice weekly.

Training and Evaluating Multimodal Word Embeddings with Large-scale Web Annotated Images (2016)

In this paper, we focus on training and evaluating effective word embeddings with both text and visual information. More specifically, we introduce a large-scale dataset with 300 million sentences describing over 40 million images crawled and downloaded from publicly available Pins (i.e. an image with sentence descriptions uploaded by users) on Pinterest. This dataset is more than 200 times larger than MS COCO, the standard large-scale image dataset with sentence descriptions. In addition, we construct an evaluation dataset to directly assess the effectiveness of word embeddings in terms of finding semantically similar or related words and phrases. The word/phrase pairs in this evaluation dataset are collected from the click data with millions of users in an image search system, thus contain rich semantic relationships. Based on these datasets, we propose and compare several Recurrent Neural Networks (RNNs) based multimodal (text and image) models. Experiments show that our model benefits from incorporating the visual information into the word embeddings, and a weight sharing strategy is crucial for learning such multimodal embeddings.

Decoralin Analogs with Increased Resistance to Degradation and Lower Hemolytic Activity (2017)

Abstract Decoralin is an antimicrobial peptide with activity against microorganisms and pronounced hemolytic activity. Decoralin analogs have been proposed, and the results indicated that when isoleucine at position 6 was substituted by phenylalanine residue, the peptides exhibited increased resistance towards enzymes action. Besides that, lower hemolytic activity was obtained for [Pro] 4 ‐Decoralin‐NH 2 and [Phe] 6 ‐Des[Thr] 11 ‐Decoralin‐NH 2 ; this effect is probably due to their poor helical tendency. [Arg] 1 ‐Decoralin‐NH 2 exhibited +4 net charge and lower hemolytic activity (25.0 μmol L −1 ) and even showed helical propensity; as a consequence, it presented the higher therapeutic indexes (values from 16.0 to 32.0). The helical conformational tendency is believed to be determinant of the antimicrobial activity of this decoralin family and has been shown to be as important as the increased positive net charge. This points to a new direction for the design of potential chemotherapeutic agents.
Development of Large Aperture PRISM-FFAG Magnet (2008)

The magnetic field of three scaled‐radial‐sector fixed field alternating gradient (FFAG)‐magnets has been measured. The measurements results are compared to a three‐dimensional field analysis using the TOSCA code; the generated magnetic field agrees satisfactorily with the TOSCA calculation in a range of 0.5%. Tracking simulation with the measured‐field map has been performed and compared to that with the TOSCA field map.
Bottom-Up Synthesis of Liquid-Phase-Processable Graphene Nanoribbons with Near-Infrared Absorption (2014)

Structurally defined, long (>100 nm), and low-band-gap (∼1.2 eV) graphene nanoribbons (GNRs) were synthesized through a bottom-up approach, enabling GNRs with a broad absorption spanning into the near-infrared (NIR) region. The chemical identity of GNRs was validated by IR, Raman, solid-state NMR, and UV–vis–NIR absorption spectroscopy. Atomic force microscopy revealed well-ordered self-assembled monolayers of uniform GNRs on a graphite surface upon deposition from the liquid phase. The broad absorption of the low-band-gap GNRs enables their detailed characterization by Raman and time-resolved terahertz photoconductivity spectroscopy with excitation at multiple wavelengths, including the NIR region, which provides further insights into the fundamental physical properties of such graphene nanostructures.
Defective suppression in the autologous mixed lymphocyte reaction in patients with Crohn's disease. (1989)

T helper and suppressor cell control of autologous immunoglobulin production was measured in 14 patients with Crohn's disease (CD) using autologous B cells or monocytes to stimulate regulatory T-cell activity. A pronounced defect in suppressor cell function was observed in the patient group but not in matched controls irrespective of whether B cells or monocytes were used as the stimulus. This defect was observed for IgG, A and M. This defect was seen both in patients with active disease and with inactive CD suggesting the possibility that a primary regulatory defect might exist in this disease. The patient group displayed normal helper cell function.
Wound healing activity of ethanolic extract of Shorea robusta Gaertn. f. resin. (2012)

The ethanolic extract of S. robusta resin (10 and 30 % w/w applied locally in excised and incised wounds) produced a dose-dependent acceleration in wound contraction and increased hydroxyproline content and tensile strength of wounds in rats. The results demonstrate wound healing activity of ethanolic extract of S. robusta resin.
Laboratory medicine: the precursors strike back. (2011)

Laboratory Medicine represents a major component of healthcare and nowadays it is involved in more than seventy percent of medical decisions. The value of any innovative laboratory test will depend on its clinical sensitivity and specificity. This clinical value is of course influenced by the analytical performance and reliability of the assay. Some spectacular advances in the understanding of circulating forms were recently accomplished with an emphasis place on prohormones and analytes precursors. Release of prohormones in the blood flow may be of major impact to improve diagnosis and risk stratification but may also influence the analytical specificity of some commercial assays. The goal of this short review is to discuss some perspectives related to some analytes' precursors that have recently been evidenced to affect assay specificity or increase assay discriminatory power.
Genome Editing: A New Approach to Human Therapeutics (2015)

The ability to manipulate the genome with precise spatial and nucleotide resolution (genome editing) has been a powerful research tool. In the past decade, the tools and expertise for using genome editing in human somatic cells and pluripotent cells have increased to such an extent that the approach is now being developed widely as a strategy to treat human disease. The fundamental process depends on creating a site-specific DNA double-strand break (DSB) in the genome and then allowing the cell's endogenous DSB repair machinery to fix the break such that precise nucleotide changes are made to the DNA sequence. With the development and discovery of several different nuclease platforms and increasing knowledge of the parameters affecting different genome editing outcomes, genome editing frequencies now reach therapeutic relevance for a wide variety of diseases. Moreover, there is a series of complementary approaches to assessing the safety and toxicity of any genome editing process, irrespective of the underlying nuclease used. Finally, the development of genome editing has raised the issue of whether it should be used to engineer the human germline. Although such an approach could clearly prevent the birth of people with devastating and destructive genetic diseases, questions remain about whether human society is morally responsible enough to use this tool.
