An efficient block Newton-type algorithm (2002)

The algorithm presented in the paper is an exact block processing counterpart of the fast Newton transversal filtering (FNTF) algorithm [Moustakides and Theodorides, 1991]. The main trait of the new algorithm is that the block processing is done in such a way so that the resulting estimates are mathematically equivalent with the respective estimates of the FNTF algorithm. In cases where the involved filter is of medium to long order the new algorithm offers a substantial saving in computational complexity without sacrificing performance.
Authentication and Access Control in e-Health Systems in the Cloud (2016)

The opportunity to access on-demand, unbounded computation and storage resources has increasingly motivated users to move their health records from local data centers to the cloud environment. This change can reduce the costs associated with the management of data sharing, communication overhead and improve Quality of Service (QoS). Processing, storing, hosting and archiving data related to e-Health systems without physical access and control can exacerbate authentication and access control issues in this new environment. Therefore, convincing users to move sensitive medical records to the cloud environment requires implementing secure and strong authentication and access control methods to protect the data. This paper proposes a new information access method that preserves both authentication and access control in cloud-based e-Health systems. Our method is based on a zero-knowledge protocol combined with two-stage keyed access control. In each access request, based on the maximum rights of user, the minimum access is extracted. To establish secure connections between different entities in the system, a two-step combination of public key encryption and DUKPT is used. We analyze our scheme with respect to data confidentiality and resistance to common attacks on the network. Experimental results show that the proposed method tolerates a high number of concurrent authentication requests with a reasonable response time.

Dealing with Lack of Training Data for Convolutional Neural Networks: The Case of Digital Pathology (2019)

Thanks to their capability to learn generalizable descriptors directly from images, deep Convolutional Neural Networks (CNNs) seem the ideal solution to most pattern recognition problems. On the other hand, to learn the image representation, CNNs need huge sets of annotated samples that are unfeasible in many every-day scenarios. This is the case, for example, of Computer-Aided Diagnosis (CAD) systems for digital pathology, where additional challenges are posed by the high variability of the cancerous tissue characteristics. In our experiments, state-of-the-art CNNs trained from scratch on histological images were less accurate and less robust to variability than a traditional machine learning framework, highlighting all the issues of fully training deep networks with limited data from real patients. To solve this problem, we designed and compared three transfer learning frameworks, leveraging CNNs pre-trained on non-medical images. This approach obtained very high accuracy, requiring much less computational resource for the training. Our findings demonstrate that transfer learning is a solution to the automated classification of histological samples and solves the problem of designing accurate and computationally-efficient CAD systems with limited training data.
A Family of New Ergonomic Harness Mechanisms for Full-Body Natural Constrained Motions in Virtual Environments (2007)

A family of new virtual reality harness mechanisms has been developed by this investigator to constrain an immersed user within the field of view of a virtual locomotion sensing system while permitting natural motions such as twisting, turning, jogging in place, dropping to the knees or moving to a prone position. The author has also developed a generalized synthesis approach to the design of such harness systems. Unwanted rotational inertial loads felt by the user are minimized while compliant constraints have been tailored to provide natural feedback forces. These ergonomic forces enhance the experience of virtual motion by partially substituting for the missing real-world dynamic loads encountered in locomotion. They also provide subtle, natural cues to the immersed user that aid the user in remaining centered. Unlike some other virtual locomotion systems, these devices are passive, relatively low-cost, easy and natural to use, making them minimally intrusive on the process of learning the simulated task

Preterm Delivery and Low Birth Weight — A Dire Legacy (1995)

The poor performance of the United States in the international ranking of infant mortality rates is mainly due to high rates of premature birth and associated low birth weight, which have changed little during the past 50 years and may recently even have increased.1 Besides its impact on infant mortality, low birth weight is associated with increased childhood morbidity, including that from respiratory illnesses, impaired postnatal growth, and neurodevelopmental problems. Although these complications increase in frequency with decreasing birth weight, even children at the upper end of the low-birth-weight range who require no intensive care have poorer outcomes than children . . .
The consequences of disrupting cardiac inwardly rectifying K<sup>+</sup> current (<i>I</i><sub>K1</sub><b>)</b> as revealed by the targeted deletion of the murine <i>Kir2.1</i> and <i>Kir2.2</i> genes (2001)

1. Ventricular myocytes demonstrate a steeply inwardly rectifying K(+) current termed I(K1). We investigated the molecular basis for murine I(K1) by removing the genes encoding Kir2.1 and Kir2.2. The physiological consequences of the loss of these genes were studied in newborn animals because mice lacking Kir2.1 have a cleft palate and die shortly after birth. 2. Kir2.1 (-/-) ventricular myocytes lack detectable I(K1) in whole-cell recordings in 4 mM external K(+). In 60 mM external K(+) a small, slower, residual current is observed. Thus Kir2.1 is the major determinant of I(K1). Sustained outward K(+) currents and Ba(2+) currents through L- and T-type channels were not significantly altered by the mutation. A 50 % reduction in I(K1) was observed in Kir2.2 (-/-) mice, raising the possibility that Kir2.2 can also contribute to the native I(K1). 3. Kir2.1 (-/-) myocytes showed significantly broader action potentials and more frequent spontaneous action potentials than wild-type myocytes. 4. In electrocardiograms of Kir2.1 (-/-) neonates, neither ectopic beats nor re-entry arrhythmias were observed. Thus the increased automaticity and prolonged action potential of the mutant ventricular myocytes were not sufficiently severe to disrupt the sinus pacing of the heart. The Kir2.1 (-/-) mice, however, had consistently slower heart rates and this phenotype is likely to arise indirectly from the influence of Kir2.1 outside the heart. 5. Thus Kir2.1 is the major component of murine I(K1) and the Kir2.1 (-/-) mouse provides a model in which the functional consequences of removing I(K1) can be studied at both cellular and organismal levels.
Partial deletions of the long and short arm of chromosome 3 point to two tumor suppressor genes in uveal melanoma. (2001)

Uveal melanoma is the most common form of primary eye cancer. Monosomy 3, which is an unusual finding in tumors but is present in approximately 50% of uveal melanomas, is significantly correlated with metastatic disease. To obtain positional information on putative tumor suppressor genes on this chromosome, we have investigated tumors from 333 patients by comparative genomic hybridization, microsatellite analysis, or conventional karyotype analysis. A partial deletion of the long arm was found in eight tumors, and the smallest region of deletion overlap (SRO) spans 3q24-q26. We found six tumors with a partial deletion of the short arm and were able to define a second SRO of about 2.5 Mb in 3p25. This SRO does not overlap with the VHL gene. Our finding suggests a role for two tumor suppressor genes in metastasizing uveal melanoma and may explain the loss of an entire chromosome 3 in these tumors.
An overview of industrial X-ray computed tomography. (2012)

Driven by the need for quality control of complex three-dimensional engineering components, and enabled by progress in medical imaging and consumer graphics processing, X-ray computed tomography (XCT) has been increasingly used for industrial inspection in recent years. A review of the recent development of industrial XCT systems in the context of traceable dimensional metrology is presented. The market trends of industrial XCT systems are briefly reviewed. Progress towards standards and methods for XCT calibration and verification are studied in detail. The report also covers the recent development of both hardware and software and discusses the challenges regarding systematic errors. Commercial systems are summarised to establish the capability available to the industrial user. Finally, what will be required to develop XCT technology in the field of dimensional metrology is considered.

Respiratory sounds classification using cepstral analysis and Gaussian mixture models (2005)

The Cepstral analysis is proposed with Gaussian Mixture Models (GMM) method to classify respiratory sounds in two categories: normal and wheezing. The sound signal is divided in overlapped segments, which are characterized by a reduced dimension feature vectors using Mel-Frequency Cepstral Coefficients (MFCC) or subband based Cepstral parameters (SBC). The proposed schema is compared with other classifiers: Vector Quantization (VQ) and Multi-Layer Perceptron (MLP) neural networks. A post processing is proposed to improve the classification results.
Practice Parameter: Treatment of postherpetic neuralgia: [RETIRED] (2004)

A systematic review of the literature on postherpetic neuralgia was performed. The authors identified studies using the National Library of Medicine's Medline database and Cochrane Library database. The authors determined absolute reduction rate, number needed to treat (NNT), 95% CI for NNT, and number needed to harm (NNH) for successful therapies of postherpetic neuralgia. Tricyclic antidepressants, gabapentin, pregabalin, opioids, and lidocaine patch were found to be effective in reducing the pain of postherpetic neuralgia.
Ginsenoside Rg1 nanoparticle penetrating the blood&ndash;brain barrier to improve the cerebral function of diabetic rats complicated with cerebral infarction (2017)

Diabetic cerebral infarction is with poorer prognosis and high rates of mortality. Ginsenoside Rg1 (Rg1) has a wide variety of therapeutic values for central nervous system (CNS) diseases for the neuron protective effects. However, the blood-brain barrier (BBB) restricts Rg1 in reaching the CNS. In this study, we investigated the therapeutic effects of Rg1 nanoparticle (PHRO, fabricated with γ-PGA, L-PAE (H), Rg1, and OX26 antibody), targeting transferrin receptor, on the diabetes rats complicated with diabetic cerebral infarction in vitro and in vivo. Dynamic light scattering analysis shows the average particle size of PHRO was 79±18 nm and the polydispersity index =0.18. The transmission electron microscope images showed that all NPs were spherical in shape with diameters of 89±23 nm. PHRO released Rg1 with sustained release manner and could promote the migration of cerebrovascular endothelial cells and tube formation and even penetrated the BBB in vitro. PHRO could penetrate the BBB with high concentration in brain tissue to reduce the cerebral infarction volume and promote neuronal recovery in vivo. PHRO was promising to be a clinical treatment of diabetes mellitus with cerebral infarction.
Spam filtering email classification (SFECM) using gain and graph mining algorithm (2017)

This paper proposes a hybrid solution of spam email classifier using context based email classification model as main algorithm complimented by information gain calculation to increase spam classification accuracy. Proposed solution consists of three stages email pre-processing, feature extraction and email classification. Research has found that LingerIG spam filter is highly effective at separating spam emails from cluster of homogenous work emails. Also experiment result proved the accuracy of spam filtering is 100% as recorded by the team of developers at University of Sydney. The study has shown that implementing the spam filter in the context-based email classification model is feasible. Experiment of the study has confirmed that spam filtering aspect of context-based classification model can be improved.
Immunotherapy for Bladder Cancer Using Recombinant Bacillus Calmette-Guerin DNA Vaccines and Interleukin-12 DNA Vaccine (2004)

Highly immunopotent recombinant vaccines of bacillus Calmette-Guerin DNA were produced that elicited T helper 1 immune responses with a high serum interferon-gamma level, inhibited tumor growth and prolonged the survival of tumor bearing mice. Thus, electroporation immunogene therapy using poly-rBCG plus mIL-12 may be an attractive regimen for the treatment of bladder cancer.

Measurement of transit time of digesta through sections of gastrointestinal tract of pigs fed with diets containing various sources of dietary fibre (non-starch polysaccharides) (1990)

The effects of various sources of dietary fibre (defined as non-starch polysaccharides (NSP] on the transit time (TT) of digesta through sections of digestive tract were measured in pigs of 30-85 kg. The pigs were fitted with simple cannulas in the terminal ileum, caecum and mid-colon. Diets in experiments 1-3 were based on barley, wheat, soya bean meal and fish meal with NSP added in the form of wood cellulose (experiment 1), guar gum (experiment 2), wheat bran, pectin (experiment 3). Lactulose was also included in experiment 3 because of its NSP-like effects. Diets in experiments 4 and 5 were based on starch and casein and contained Phaseoluos vulgaris or Pisum sativum (experiment 4) and sugar beet pulp or wheat bran (experiment 5). Transit time (TT) was measured using 103Ruthenium phenanthroline to label solids and 51Chromium complexed to EDTA for liquids. Samples were taken every 3 h after marker administration for 51 h from all cannulas and the faecal output was collected every 3 h. The values obtained were very variable. The range of TT (h) defined as first arrival of markers and peak marker level was 3-12.2 and 3-12.2 to the ileum, 3-22.3 and 4.5-22.3 to the caecum, 4.5-50.3 and 16.5-48.8 to the colon and 24- less than 51 and 30- less than 51 to the rectum respectively.
Excitotoxicity and Selective Neuronal Loss in Epilepsy (1993)

The early stages of selective neuronal loss occurring in the hippocampus and other brain regions after prolonged epileptic activity have fine structural characteristics matching those induced by excitotoxic agents. NMDA receptor antagonists provide protection against such damage. The extracellular concentration of glutamate or aspartate may be transiently raised prior to or early in seizure activity but tends not to match the levels associated with hypothalamic damage in the original paradigm of excitotoxicity. Various aspects of the excitotoxic process are examined to see if they can account for particular details of the pattern of selective neuronal loss. A full explanation of selective vulnerability will take into account not only a range of characteristics of the vulnerable neuron but also its functional network during sustained activity.
Multiple Window Correlation Analysis of HRV Power and Respiratory Frequency (2007)

In this paper, we evaluate the correlation estimate, based on multiple window spectrum analysis, between the respiratory center frequency and the high-frequency band of the heartrate variability (HRV) power. One aim is to examine whether a more restricted frequency range would better capture respiratory related HR variation, especially when the HR variation is changing rapidly. The respiratory peak is detected and a narrow-banded measure of the high-frequency (HF) band of the HRV is defined as the respiratory frequency +/-0.05 Hz. We compare the mean square error of the correlation estimate between the frequency of the respiratory peak and the power of the HRV with the power in the usual 0.12-0.4 Hz frequency band. Different multiple window spectrum techniques are used for the estimation of the respiratory frequency as well as for the power of the HRV. We compare the peak-matched multiple windows with the Welch method while evaluating the two different HF-power estimates mentioned above. The results show that using a more narrow band for the power estimation gives stronger correlation which indicates that the estimate of the power is more robust.
Sequence and Positional Requirements for DNA Sites in a Mu Transpososome (2002)

Transposition of bacteriophage Mu uses two DNA cleavage sites and six transposase recognition sites, with each recognition site divided into two half-sites. The recognition sites can activate transposition of non-Mu DNA sequences if a complete set of Mu sequences is not available. We have analyzed 18 sequences from a non-Mu DNA molecule, selected in a functional assay for the ability to be transposed by MuA transposase. These sequences are remarkably diverse. Nonetheless, when viewed as a group they resemble a Mu DNA end, with a cleavage site and a single recognition site. Analysis of these "pseudo-Mu ends" indicates that most positions in the cleavage and recognition sites contribute sequence-specific information that helps drive transposition, though only the strongest contributors are apparent from mutagenesis data. The sequence analysis also suggests variability in the alignment of recognition half-sites. Transposition assays of specifically designed DNA substrates support the conclusion that the transposition machinery is flexible enough to permit variability in half-site spacing and also perhaps variability in the placement of the recognition site with respect to the cleavage site. This variability causes only local perturbations in the protein-DNA complex, as indicated by experiments in which altered and unaltered DNA substrates are paired.
