Accurate iris segmentation in non-cooperative environments using fully convolutional networks (2016)

Conventional iris recognition requires controlled conditions (e.g., close acquisition distance and stop-and-stare scheme) and high user cooperation for image acquisition. Non-cooperative acquisition environments introduce many adverse factors such as blur, off-axis, occlusions and specular reflections, which challenge existing iris segmentation approaches. In this paper, we present two iris segmentation models, namely hierarchical convolutional neural networks (HCNNs) and multi-scale fully convolutional network (MFCNs), for noisy iris images acquired at-a-distance and on-the-move. Both models automatically locate iris pixels without handcrafted features or rules. Moreover, the features and classifiers are jointly optimized. They are end-to-end models which require no further pre- and post-processing and outperform other state-of-the-art methods. Compared with HCNNs, MFCNs take input of arbitrary size and produces correspondingly-sized output without sliding window prediction, which makes MFCNs more efficient. The shallow, fine layers and deep, global layers are combined in MFCNs to capture both the texture details and global structure of iris patterns. Experimental results show that MFCNs are more robust than HCNNs to noises, and can greatly improve the current state-of-the-arts by 25.62% and 13.24% on the UBIRIS.v2 and CASIA.v4-distance databases, respectively.
Enamel Fluoride Retention after DCPD and APF Application and Prolonged Exposure to Fluoride in vitro (1986)

The effect of a topical fluoride regimen consisting of a four-minute pre-treatment with a saturated dicalcium phosphate dihydrate (DCPD) solution followed by a four-minute application of APF was compared with that of a four-minute application of APF alone with respect to the deposition of fluoride in enamel in an apatitic form in vitro. Following the topical applications, specimens were washed in either (1) an inorganic wash solution for 24 hrs or (2) an inorganic wash solution with 1 ppm F added for 28 days; specimens were then subjected to KOH extraction for 24 hrs. Fluoride-by-depth profiles revealed that the DCPD/APF treatment resulted in a significant increase in the apatitic F concentration of enamel to a depth of 20 microns, while APF application alone did not. All groups exposed to the 1 ppm F wash acquired significant amounts of apatitic F, with the differences between groups remaining relatively constant.
Evidence against a circulating ouabain-like transport inhibitor as a cause of increased red cell sodium in essential hypertension. (1984)

Red cell sodium and potassium concentrations, and total ouabain-sensitive and ouabain-insensitive first order red constants for sodium efflux, were measured in 15 patients (11 female, 4 male) with essential hypertension (162 +/- 14/99 +/- 7 (s.d. mmHg) and 15 normotensive control subjects (117 +/- 17/64 +/- 10 mmHg) individually matched for age (45.8 +/- 10 versus 45.7 +/- 10 years, respectively, sex, weight (68.6 +/- 16.1 versus 64.7 +/- 11.2 kg) and blood group. To test for possible plasma inhibitors of sodium transport in hypertension, total efflux rate constants were measured in red cells incubated in two plasma samples, from either the same or the complementary (paired) subjects, respectively. Intracellular sodium was significantly increased in patients (11.8 +/- 3.45 versus 8.75 +/- 2.48 mmols/l of red cell water; P = 0.023). Intracellular potassium and total and ouabain-sensitive sodium efflux rate constants, were similar in both groups. Sodium efflux was similar when cells were incubated in the homologous and complementary plasma samples. Ouabain-insensitive rate constants were decreased in the patients (0.16 +/- 0.08 versus 0.20 +/- 0.05 h-1) but the difference was of borderline significance (P = 0.059). These results confirm the presence of abnormal intracellular sodium concentrations and membrane transport in essential hypertension but are not consistent with the suggestion that the abnormalities are due to a circulating sodium transport inhibitor.

Establishment of pseudovirus infection mouse models for in vivo pharmacodynamics evaluation of filovirus entry inhibitors (2017)

Filoviruses cause severe and fatal viral hemorrhagic fever in humans. Filovirus research has been extensive since the 2014 Ebola outbreak. Due to their high pathogenicity and mortality, live filoviruses require Biosafety Level-4 (BSL-4) facilities, which have restricted the development of anti-filovirus vaccines and drugs. An HIV-based pseudovirus cell infection assay is widely used for viral entry studies in BSL-2 conditions. Here, we successfully constructed nine <i>in vitro</i> pseudo-filovirus models covering all filovirus genera and three <i>in vivo</i> pseudo-filovirus-infection mouse models using Ebola virus, Marburg virus, and Lloviu virus as representative viruses. The pseudo-filovirus-infected mice showed visualizing bioluminescence in a dose-dependent manner. A bioluminescence peak in mice was reached on day 5 post-infection for Ebola virus and Marburg virus and on day 4 post-infection for Lloviu virus. Two known filovirus entry inhibitors, clomiphene and toremiphene, were used to validate the model. Collectively, our study shows that all genera of filoviruses can be well-pseudotyped and are infectious <i>in vitro</i>. The pseudo-filovirus-infection mouse models can be used for <i>in vivo</i> activity evaluation of anti-filovirus drugs. This sequential <i>in vitro</i> and <i>in vivo</i> evaluation system of filovirus entry inhibitors provides a secure and efficient platform for screening and assessing anti-filovirus agents in BSL-2 facilities.
Synthesis and characterization of CdS/multiwalled carbon nanotube heterojunctions (2004)

CdS nanoparticles were successfully immobilized on multiwalled carbon nanotubes (MWNTs) via a simple solvothermal approach using dimethyl sulfoxide (DMSO) both as medium and sulfur source. The dependences of size and morphology of CdS nanoparticles on the reaction duration, Cd2+ concentration, and medium were investigated. IR, thermogravimetry–differential scanning calorimetry (TG–DSC), and UV–vis spectrometry were performed to understand the interaction between CdS nanoparticles and MWNTs.

Resilience in live peer-to-peer streaming [Peer-to-Peer Multimedia Streaming] (2007)

The success of peer-to-peer overlays for live multicast streaming depends on their ability to maintain low delays and a low ratio of information loss end-to-end. However, data distribution over an overlay consisting of unreliable peers is inherently subject to disturbances. Resilience is thus inevitably a key requirement for peer-to-peer live-streaming architectures. In this article, we present a survey of the media distribution methods, overlay structures, and error-control solutions proposed for peer-to-peer live streaming. We discuss the trade off between resilience and overhead and argue that efficient architectures can be defined only through thorough performance analysis.
Amantadine-induced conformational and dynamical changes of the influenza M2 transmembrane proton channel (2008)

The M2 protein of influenza A virus forms a transmembrane proton channel important for viral infection and replication. Amantadine blocks this channel, thus inhibiting viral replication. Elucidating the high-resolution structure of the M2 protein and its change upon amantadine binding is crucial for designing antiviral drugs to combat the growing resistance of influenza A viruses against amantadine. We used magic-angle-spinning solid-state NMR to determine the conformation and dynamics of the transmembrane domain of the protein M2TMP in the apo- and amantadine-bound states in lipid bilayers. (13)C chemical shifts and torsion angles of the protein in 1,2-dilauroyl-sn-glycero-3-phosphatidylcholine (DLPC) bilayers indicate that M2TMP is alpha-helical in both states, but the average conformation differs subtly, especially at the G34-I35 linkage and V27 side chain. In the liquid-crystalline membrane, the complexed M2TMP shows dramatically narrower lines than the apo peptide. Analysis of the homogeneous and inhomogeneous line widths indicates that the apo-M2TMP undergoes significant microsecond-time scale motion, and amantadine binding alters the motional rates, causing line-narrowing. Amantadine also reduces the conformational heterogeneity of specific residues, including the G34/I35 pair and several side chains. Finally, amantadine causes the helical segment N-terminal to G34 to increase its tilt angle by 3 degrees , and the G34-I35 torsion angles cause a kink of 5 degrees in the amantadine-bound helix. These data indicate that amantadine affects the M2 proton channel mainly by changing the distribution and exchange rates among multiple low-energy conformations and only subtly alters the average conformation and orientation. Amantadine-resistant mutations thus may arise from binding-incompetent changes in the conformational equilibrium.
Correlation of clinical, magnetic resonance imaging, and cerebrospinal fluid findings in optic neuritis (1997)

We found 42 of 74 patients (57%) with isolated monosymptomatic optic neuritis to have 1 to 20 brain lesions, by magnetic resonance imaging (MRI). All of the brain lesions were clinically silent and had characteristics consistent with multiple sclerosis (MS). None of the patients had ever experienced neurologic symptoms prior to the episode of optic neuritis. During 5.6 years of follow-up, 21 patients (28%) developed definite MS on clinical grounds. Sixteen of the 21 converting patients (76%) had abnormal MRIs; the other 5 (24%) had MRIs that were normal initially (when they had optic neuritis only) and when repeated after they had developed clinical MS in 4 of the 5. Of the 53 patients who have not developed clinically definite MS, 26 (49%) have abnormal MRIs and 27 (51%) have normal MRIs. The finding of an abnormal MRI at the time of optic neuritis was significantly related to the subsequent development of MS on clinical grounds, but interpretation of the strength of that relationship must be tempered by the fact that some of the converting patients had normal MRIs and approximately half of the patients who did not develop clinical MS had abnormal MRIs. We found that abnormal IgG levels in the cerebrospinal fluid correlated more strongly than abnormal MRIs with the subsequent development of clinically definite MS.

Lateral-shearing interferometer using square prisms for optical testing of aspheric lenses (1998)

We present a lateral-shearing interferometer specially devised for production-line inspection of aspheric lenses. The interferometer constitutes four right-angle prisms, whose relative sliding motions provide the lateral shearing and phase shifts necessary for measuring the beam wavefront collimated by the lens under test. The prisms are held together face to face using index-matching oil, so environmental disturbances from external vibration and atmospheric turbulence can be minimized. Furthermore, a special phase-measuring algorithm of least-squares type is adopted to compensate for the phase shift error caused by the variation in thickness of the index-matching oil holding the prisms. Experimental results prove that the interferometer provides a measuring reproducibility of the order of one hundredth of the light's wavelength.

Control of the Growth Optimum in Producing High‐Quality CaF<sub>2</sub>Crystals by an Improved Bridgman‐Stockbarger Technique (1996)

Abstract The axial temperature distribution in an empty crucible and the determination of quenched interface within fixed crucible were investigated to find the relationships governing the growing process of CaF 2 by Bridgman‐Stockbarger methods. A system of additional molybdenum reflective sheaths was placed into the furnace unit and its effect on the temperature field was estimated in order to achieve the growth optimum. A long liner into the diaphragm bore of the furnace and a number of thin rings slipped on the crucible stem were found capable to provide a reproducible optimum on each stage of growing in single and multicamera crucibles at a relatively low level of power supply. Single and in‐group growth experiments were carried out using high density quenched ingots purified from oxygen contaminants through high temperature treatment of fluorspar. The properties of the grown crystals were found to depend on the degree of the fluorspar purification and on the improvement of the thermal conditions yielding either competitor or laser‐grade CaF 2 . In multicamera crucibles the crystals grown in the central compartment are of better characteristics than those in the peripheral ones.
Constructing Red−Black Trees (1999)

This paper explores the structure of red-black trees by solving an apparently simple problem: given an ascending sequence of elements, construct a red-black tree which contains the elements in symmetric order. Several extreme red-black tree shapes are characterized: trees of minimum and maximum height, trees with a minimal and with a maximal proportion of red nodes. These characterizations are obtained by relating tree shapes to various number systems. In addition, connections to left-complete trees, AVL trees, and half-balanced trees are highlighted. 1 Introduction Red-black trees are an elegant search-tree scheme that guarantees O(log n) worstcase running time of basic dynamic-set operations. Recently, C. Okasaki (1998; 1999) presented an impressively simple functional implementation of red-black trees. In this paper we plunge deeper into the structure of red-black trees by solving an apparently simple problem: given an ascending sequence of elements, construct a red-black tree whic...

Libraries in university towns (2006)

The period between the end of the English Civil War (and its associated conflicts in Ireland and Scotland) and the mid-eighteenth century has not generally been regarded as one of great intellectual distinction in the universities of these islands. Their number remained the same throughout the period, showing no increase on those in existence at the end of the sixteenth century. There were Oxford and Cambridge in England; the newly founded (1592) Trinity College, Dublin, in Ireland; and in Scotland the fifteenth-century foundations of Glasgow and St Andrews, the recent (1582) Edinburgh, and in Aberdeen King's College and Marischal College, which were united in one university in 1641 and separated just after the Restoration in 1660.

Agarose Droplet Microfluidics for Highly Parallel and Efficient Single Molecule Emulsion PCR (2012)

Agarose emulsion droplet microfluidic technology for single copy emulsion PCR (ePCR) is a suitable technique for the detection of single copy DNA molecules. It improves the traditional ePCR by employing agarose with low melting and low gelling temperatures, which is coupled with PCR forward primers using Schiff-base reaction. Highly uniform monodisperse nanoliter agarose droplets each containing PCR reagents and single copy template are produced with a microfabricated emulsion generator. Following PCR, the cooled droplets transform to microbeads carrying amplicons to maintain the monocolonity of each droplet, which can be further analyzed. This method allows high-throughput generation of uniform droplets and enables high PCR efficiency, making it a promising platform for many single copy genetic studies.
