Wavelet Transform-based Network Traffic Prediction: A Fast On-line Approach (2012)

High speed network traffic prediction is essential to provision QoS for multimedia applications while keeping bandwidth utilization high. Wavelet transform is a powerful technique for analyzing time domain signals. When combined with LMS, wavelet based predictor can achieve better performance than time domain predictor for MPEG-4 VBR videos and self-similar traffic. However, the computational complexity in predicting each wavelet coefficient is high. In this paper, LMK (Least Mean Kurtosis), which uses the negated kurtosis of the error signal as the cost function, is first proposed to estimate wavelet coefficients, then, by analyzing the wavelet coefficients of two consecutive data sets, Reduced Computation Complexity Wavelet LMK (RCCWLMK) is proposed to reduce the computational complexity. Simulation results for a wide range of MPEG-4 videos and network self-similar traffic show that RCCWLMK not only incurs smaller prediction error, but also reduces the computational complexity greatly.
Fitting pinna-related transfer functions to anthropometry for binaural sound rendering (2010)

This paper faces the general problem of modeling pinna-related transfer functions (PRTFs) for 3-D sound rendering. Following a structural approach, we aim at constructing a model for PRTF synthesis which allows to control separately the evolution of ear resonances and spectral notches through the design of two distinct filter blocks. Taking such model as endpoint, we propose a method based on the McAulay-Quatieri partial tracking algorithm to extract the frequencies of the most important spectral notches. Ray-tracing analysis performed on the so obtained tracks reveals a convincing correspondence between extracted frequencies and pinna geometry of a bunch of subjects.
Preventing document leakage through active document (2014)

Electronic documents inside any enterprise environment are assets that add to the enterprise's capital in intellectual property such as design patents or customer information, securing, these assets is a priority requirement in any security system design. The security of these documents suffers when they have migrated outside the organisation security system, as there is not always possible to extend the enterprise security policy to limit/prevent access to those assets. This limitation in extending the originating security policy may be due to difference in technology used, domain or security policy. This paper presents the challenges faced when preventing document leakage. We propose active document as a measure to control/limit access when electronic document are outside its domain.
SOME HATCHERY FACTORS INVOLVED IN EARLY CHICK MORTALITY (1979)

Observations made in a commerical broiler hatchery revealed that chicks hatched over a period of 48 hours. Chick mortality to 10 days of age was 3.2% for those hatched at the commencement of the hatch, 1.2% for those hatched at peak of hatch and 52.9% for those hatched at the end of hatching. Chicks hatched early were more prone to dehydration while late hatching chicks had a higher incidence of leg weakness. Chicks held for 48 hours in hatcher machines lost 12.5% to 21.7% of their hatching weight and 79.4% of the hatching weight of the yolk sac. Normal 10-day mortality from this hatchery in winter months was observed to be 2.4% but was reduced to 1.2% when staggered setting times of donor flocks was employed by removing chicks from the machines 3 hours after 100% hatch, but was increased to 5.6% by holding chicks in the hatchery in chick boxes for 24 hours at 70 degrees C.
Full Quantification of Left Ventricle via Deep Multitask Learning Network Respecting Intra- and Inter-Task Relatedness (2017)

Cardiac left ventricle (LV) quantification is among the most clinically important tasks for identification and diagnosis of cardiac diseases, yet still a challenge due to the high variability of cardiac structure and the complexity of temporal dynamics. Full quantification, i.e., to simultaneously quantify all LV indices including two areas (cavity and myocardium), six regional wall thicknesses (RWT), three LV dimensions, and one cardiac phase, is even more challenging since the uncertain relatedness intra and inter each type of indices may hinder the learning procedure from better convergence and generalization. In this paper, we propose a newly-designed multitask learning network (FullLVNet), which is constituted by a deep convolution neural network (CNN) for expressive feature embedding of cardiac structure; two followed parallel recurrent neural network (RNN) modules for temporal dynamic modeling; and four linear models for the final estimation. During the final estimation, both intra- and inter-task relatedness are modeled to enforce improvement of generalization: 1) respecting intra-task relatedness, group lasso is applied to each of the regression tasks for sparse and common feature selection and consistent prediction; 2) respecting inter-task relatedness, three phase-guided constraints are proposed to penalize violation of the temporal behavior of the obtained LV indices. Experiments on MR sequences of 145 subjects show that FullLVNet achieves high accurate prediction with our intra- and inter-task relatedness, leading to MAE of 190mm$^2$, 1.41mm, 2.68mm for average areas, RWT, dimensions and error rate of 10.4\% for the phase classification. This endows our method a great potential in comprehensive clinical assessment of global, regional and dynamic cardiac function.
Preparation of N-alkylthiomethyl derivatives of hydroxylamines. (1979)

New types of methylene compounds, N-alkylthiomethyl derivatives of N-alkyl (or aryl) hydroxylamines and N, N-bis (alkylthiomethyl) hydroxylamines, have been obtained by Mannich-type condensation using thiols, formaldehyde and hydroxylamines.
End-to-end encryption at the network layer (2003)

Both network-layer and transport-layer encryption are permitted by the OSI Security Addendum. The advantages of network-layer encryption are discussed. Secure data network system (SDNS) protocols are described. In the SDNS, SP is a single, simple encryption protocol between end-systems. This protocol has two descriptions, SP3 (network layer) and SP4 (transport layer). Both definitions are OSI compliant. Extensions of the basic protocol allow SP3 to be used at intermediate systems and allow SP4 to provide a more connection-oriented service.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
An inverted FL antenna for dual-frequency operation (2005)

An inverted FL antenna (InvFLA) is analyzed to obtain dual-frequency operation at 2.45 and 5.2 GHz (wireless LAN system frequencies). The InvFLA is composed of inverted FL elements, a parasitic element, and a ground plate, where these lie in the same plane, i.e., the structure is a card-type structure having a co-planar ground plate. The antenna height above the ground plate is very small: 5.5 mm=0.045 wavelength at 2.45 GHz. The analysis shows that the InvFLA has a 4.1% bandwidth around 2.45 GHz and a 31.8% bandwidth around 5.2 GHz, both for a VSWR=2 criterion. The gain is calculated to be 0.9 dBi at 2.45 GHz and 1.7 dBi at 5.2 GHz, with a small gain variation in each of the VSWR bands.
Glucose‐Responsive Bioinorganic Nanohybrid Membrane for Self‐Regulated Insulin Release (2010)

Abstract A bioinorganic nanohybrid glucose‐responsive membrane is developed for self‐regulated insulin delivery analogous to a healthy human pancreas. The application of MnO 2 nanoparticles as a multifunctional component in a glucose‐responsive, protein‐based membrane with embedded pH‐responsive hydrogel nanoparticles is proposed. The bio‐nanohybrid membrane is prepared by crosslinking bovine serum albumin (BSA)–MnO 2 nanoparticle conjugates with glucose oxidase and catalase in the presence of poly( N ‐isopropyl acrylamide‐ co ‐methacrylic acid) nanoparticles. The preparation and performance of this new nanocomposite material for a glucose‐responsive insulin release system is presented. The activity and stability of immobilized glucose oxidase and the morphology and mechanical properties of the membrane are investigated. The enzymatic activity is well preserved in the membranes. The use of MnO 2 nanoparticles not only reinforces the mechanical strength and the porous structure of the BSA‐based membrane, but enhances the long‐term stability of the enzymes. The in vitro release of insulin across the membrane is modulated by changes in glucose concentration mimicking possible fluctuations of blood‐glucose level in diabetic patients. A four‐fold increase in insulin permeation is observed when the glucose concentration is increased from normal to hyperglycemic levels, which returns to the baseline level when the glucose concentration is reduced to a normal level.
Evaluation of Spinal Missile Injuries With Respect to Bullet Trajectory, Surgical Indications and Timing of Surgical Intervention (2008)

Anteroposterior and oblique trajectories [Gulhane Military Medical Academy (GATA)-SMI I and GATA-SMI II] of SMI must be recognized as highly infective in the lumbar region. A side-to-side trajectory (GATA-SMI III) missile causing spinal cord injury is unstable and needs further stabilization. The spinal cord is not injured by the GATA-SMI IV trajectory, and thus, the best approach in this case is conservative. The best results from neurosurgical interventions may be achieved after rapid neurologic deteriorations because of spinal compression and/or instability.
Interfacial oxide, grain size, and hydrogen passivation effects on polysilicon emitter transistors (1988)

The influence of several process variables on the characteristics of polysilicon emitter transistors is studied. The diffusion length of the polysilicon layer was increased using hydrogen passivation, resulting in an increase in the transistor current gain. The increase observed was less than that predicted by the T.H. Ning and R.D. Isaac (1980) transport model, especially at high emitter doping levels. Similarly, the polysilicon grain size had a smaller effect on the current gain than predicted by this model. On the other hand, an increase in the interfacial layer thickness caused a large increase in the emitter efficiency and also resulted in retarded arsenic diffusion and increased emitter resistance and base current ideality factor. The results suggest that reflection of minority carriers at the interface plays a dominant role in determining the emitter Gummel number in devices with heavily doped emitters.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
How do brain tumors alter functional connectivity? A magnetoencephalography study (2005)

Our findings suggest that brain tumors induce a loss of functional connectivity that affects multiple brain regions, and that left side brain tumors have the more severe consequences in this respect.
Constraint based frequent pattern mining for generalized query templates from web log (2011)

The World-Wide Web provides every Internet citizen access to an abundance of information, but difficulty increases in identifying the relevant piece of information. Popular Search engine uses log for keeping track of user activities including user queries, click-through and their behavior. Research in web mining tries to address this problem by discovering knowledge from user logs. We propose an approach to discover patterns that can predict user’s search, without aid of remote server. Our method analyses user’s interactions by constructing FP-tree, which facilitates in producing templates from the user logs. Consensus tree growth is restricted and templates are obtained from leaves, which assist user’s searching process with precision. We show the effectiveness of our method on realistic web logs and explore the tradeoff between prediction’s accuracy and usefulness. Test results show the improved algorithm has lower complexity of time and space, and fit the capacity of memory.
Efficient fair queueing algorithms for packet-switched networks (1998)

Although weighted fair queueing (WFQ) has been regarded as an ideal scheduling algorithm in terms of its combined delay bound and proportional fairness properties, its asymptotic time complexity increases linearly with the number of sessions serviced by the scheduler, thus limiting its use in high-speed networks. An algorithm that combines the delay and fairness bounds of WFQ with O(1) timestamp computations had remained elusive so far. In this paper we present two novel scheduling algorithms that have O(1) complexity for timestamp computations and provide the same bounds on end-to-end delay and buffer requirements as those of WFQ. The first algorithm, frame-based fair queueing (FFQ), uses a framing mechanism to periodically recalibrate a global variable tracking the progress of work in the system, limiting any short-term unfairness to within a frame period. The second algorithm, starting potential based fair queueing (SPFQ), performs the recalibration at packet boundaries, resulting in improved fairness while still maintaining the O(1) timestamp computations. Both algorithms are based on the general framework of rate-proportional servers (RPSs) introduced by Stiliadis and Varma (see ibid., vol.6, no.2, p.164-74, 1998). The algorithms may be used in both general packet networks with variable packet sizes and in asynchronous transfer mode (ATM) networks.
NLOS Error Mitigation for UWB Ranging in Dense Multipath Environments (2007)

To mitigate the non-line-of-sight (NLOS) error of ultra-wideband (UWB) ranging caused by obstructions in dense multipath environments, this paper proposed a novel NLOS error mitigation method. The principles and characteristics of NLOS error are analyzed. Based on the signal propagation path loss model, the NLOS error estimation expression is deduced and further used to calibrate the ranging results. Low complexity path detection algorithms are proposed for implementation of the method. Test on measured data shows that the method can improve the ranging precision greatly.
Molecular Materials for Organic Photovoltaics: Small is Beautiful (2014)

An overview of some recent developments of the chemistry of molecular donor materials for organic photovoltaics (OPV) is presented. Although molecular materials have been used for the fabrication of OPV cells from the very beginning of the field, the design of molecular donors specifically designed for OPV is a relatively recent research area. In the past few years, molecular donors have been used in both vacuum-deposited and solution-processed OPV cells and both fields have witnessed impressive progress with power conversion efficiencies crossing the symbolic limit of 10 %. However, this progress has been achieved at the price of an increasing complexity of the chemistry of active materials and of the technology of device fabrication. This evolution probably inherent to the progress of research is difficult to reconcile with the necessity for OPV to demonstrate a decisive economic advantage over existing silicon technology. In this short review various classes of molecular donors are discussed with the aim of defining possible basic molecular structures that can combine structural simplicity, low molecular weight, synthetic accessibility, scalability and that can represent possible starting points for the development of simple and cost-effective OPV materials.
Analysis of acoustic impedance matching in dual-band ultrasound transducers (2017)

Dual-frequency band probes are needed for ultrasound (US) reverberation suppression and are useful for image-guided US therapy. A challenge is to design transducer stacks that achieve high bandwidth and efficiency at both operating frequencies when the frequencies are widely separated with a frequency ratio ∼6:1-20:1. This paper studies the loading and backing conditions of transducers in such stacks. Three stack configurations are presented and analyzed using one-dimensional models. It is shown that a configuration with three layers of material separating the transducers is favorable, as it reduces high frequency ringing by ∼20 dB compared to other designs, and matches the low frequency (LF) transducer to the load at a lower frequency. In some cases, the LF load matching is governed by a simple mass-spring interaction in spite of having a complicated matching structure. The proposed design should yield improved performance of reverberation suppression algorithms. Its suitability for reduction of probe heating, also in single-band probes, should be investigated.

Establishment of a Vaporous Hydrogen Peroxide Bio-Decontamination Capability (2007)

Vaporous hydrogen peroxide (VHP) has previously been demonstrated to be effective against biological agents and to some extent chemical agents. As part of the current HPPD work program on chemical and biological decontamination a VHP decontamination system was acquired. Here we describe the commissioning of the VHP unit which involved setting up a small scale testing capability, the sterilization of a PC3 laboratory and conducting a field trial to decontaminate equipment in a tent. In each case positive results were obtained regarding the distribution of the vaporous decontaminant and its efficacy as a biological decontaminant.
Molecular Structure and Bonding of Copper Cluster Monocarbonyls Cu<i><sub>n</sub></i>CO (<i>n</i> = 1−9) (2006)

In this work we analyze CO binding on small neutral copper clusters, Cun (n = 1-9). Molecular structures and reactivity descriptors of copper clusters are computed and discussed. The results show that the condensed Fukui functions and the frontier molecular orbital theory are useful tools to predict the selectivity of CO adsorption on these small clusters. To get further insight into the CO binding to copper clusters, an energy decomposition analysis of the CO binding energy is performed. The Cs symmetry of the formed CunCO clusters (n = 1-8) allows the separation between the orbital interaction terms corresponding to donation and back-donation. It is found that, energetically, the donation is twice as important as back-donation.
Intracavity doubling of CW diode-pumped Nd:YAG lasers with KTP (1992)

Intracavity-doubled lasers exhibit amplitude fluctuations driven by a combination of two nonlinearities: sum generation and spatial hole burning. Optimizing the cavity polarizations to minimize sum generation does not consistently eliminate the oscillations. Elimination of spatial hole burning prevents oscillations over a much larger range of operating conditions. The system is still bistable however, and can suffer abrupt changes in power due to mode hops. This can be eliminated with an etalon or other wavelength selective element.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
An Immunohistochemical Study of Na<sup>+</sup>/I<sup>−</sup>Symporter in Human Thyroid Tissues and Salivary Gland Tissues (1998)

The human Na+/I- symporter (hNIS) is the plasma membrane protein that mediates active iodide uptake into several tissues, such as the thyroid and salivary glands. To study the distribution and cellular localization of the hNIS protein, we have generated a polyclonal antibody that could detect the hNIS protein by immunohistochemical staining on tissue sections. In normal thyroids, hNIS expression is heterogeneous, and it is only detected in sporadic thyrocytes of a given follicle. The hNIS protein was not detected in thyroid carcinomas, yet it was detected in the majority of thyrocytes in Graves' thyroids. In salivary glands, hNIS protein was not detected in acinar cells, but it was detected in ductal cells. The hNIS proteins are clustered in the basal and lateral membranes in cells stained positive for hNIS.

Special features of the clinical use of oral terbinafine in the treatment of fungal diseases (1992)

Terbinafine (Lamisil) is an antifungal drug, belonging to a class of drugs called the allylamines, which has recently become available for clinical use. This is a report of four special features which emerged during evaluation of the systemic use of orally administered terbinafine in the treatment of 2500 patients during the last 5 years. These features include: (i) distribution of terbinafine in skin, hair and nail tissue; (ii) use in short-duration treatment of chronic tinea pedis and onychomycosis; (iii) use in patients with serious infections often associated with local or generalized immunological defects; and (iv) tolerability and safety of the drug. The diffusion of terbinafine into thickened, chronically infected tissue and into nails, and its recognized fungicidal action are the most likely features responsible for its success in the treatment of chronic fungal diseases, including those with immunological defects. Terbinafine is well tolerated, particularly when compared with other available systemic antifungal drugs.

Multi-object optimal design of electromagnetic artificial muscle structure (2011)

An artificial muscle linear actuator is proposed based on electromagnetically technology by analysis of the skeletal muscle structure and function. By simulating the microstructure of skeletal muscle, artificial muscles are composed of numerous fascicles of artificial muscle fibers. Artificial muscle fibers are composed of artificial sarcomeres arranged in series. The structure of artificial sarcomeres is designed and optimized. The simulation indicates that the linear electromagnetic series-parallel array artificial muscle possesses some good characteristics, such as high response speed, small volume, light quality, high power density ect.. The linear electromagnetic series-parallel array artificial muscle has good prospects for actual engineering application.
