Knowledge Adaptation with PartiallyShared Features for Event DetectionUsing Few Exemplars (2014)

Multimedia event detection (MED) is an emerging area of research. Previous work mainly focuses on simple event detection in sports and news videos, or abnormality detection in surveillance videos. In contrast, we focus on detecting more complicated and generic events that gain more users' interest, and we explore an effective solution for MED. Moreover, our solution only uses few positive examples since precisely labeled multimedia content is scarce in the real world. As the information from these few positive examples is limited, we propose using knowledge adaptation to facilitate event detection. Different from the state of the art, our algorithm is able to adapt knowledge from another source for MED even if the features of the source and the target are partially different, but overlapping. Avoiding the requirement that the two domains are consistent in feature types is desirable as data collection platforms change or augment their capabilities and we should be able to respond to this with little or no effort. We perform extensive experiments on real-world multimedia archives consisting of several challenging events. The results show that our approach outperforms several other state-of-the-art detection algorithms.

Evolution à long terme de la loi de comportement d'une argile organique sous les remblais d'une autoroute urbaine (2007)

L'autoroute urbaine qui pénètre dans l'agglomération de Bordeaux franchit une vaste plaine alluvionnaire composée d'argile organique compressible. Nous présentons, dans cette communication les résultats d'essais de laboratoire effectués sur le sol organique prélevé sur ce site ayant fait l'objet d'un chargement par plusieurs ouvrages en terre pendant 30 années. Ces ouvrages expérimentaux situés à Cubzac-les-Ponts ont fait l'objet d'un suivi annuel de leur géométrie et de certains paramètres mécaniques. Une analyse critique de l'évolution des techniques d'essais triaxiaux et des choix réalisés dans l'application du mode opératoire est menée et l'influence sur la qualité des résultats d'essais est présentée. Nous analysons dans la communication l'évolution de la surface de chanrge depuis la première campagne ainsi que la loi d'écoulement après ce laps de temps.
Microdialysis Glucose Sensor System Compared With Needle Type Glucose Sensor In Vivo During OGTT And Physical Exercise (2006)

The 'subcutaneous glucose monitoring system' (SCGM) is based on microdialysis and allows continuous glucose monitoring in abdominal adipose tissue of diabetic patients up to 5 days. In the current in vivo study we compared the SCGM system with a commercially available needle type glucose sensor during an oral glucose tolerance test (OGTT) and during physical exercise. The SCGM had a good in vivo performance that was comparable to the needle type sensor. The inherent safe measuring technology of microdialysis and sensor stability of the SCGM makes it a likely candidate for online glucose measurement in diabetic patients. However, the overall system configuration is too bulky to wear comfortably and the measured values have a time lag of 35 min. The SCGM system will be the base for the future development of a miniaturized integrated microdialysis sensor system using lab-on-a-chip technology.
Overexpression of <i>groESL</i> in <i>Clostridium acetobutylicum</i> Results in Increased Solvent Production and Tolerance, Prolonged Metabolism, and Changes in the Cell's Transcriptional Program (2003)

DNA array and Western analyses were used to examine the effects of groESL overexpression and host-plasmid interactions on solvent production in Clostridium acetobutylicum ATCC 824. Strain 824(pGROE1) was created to overexpress the groESL operon genes from a clostridial thiolase promoter. The growth of 824(pGROE1) was inhibited up to 85% less by a butanol challenge than that of the control strain, 824(pSOS95del). Overexpression of groESL resulted in increased final solvent titers 40% and 33% higher than those of the wild type and plasmid control strains, respectively. Active metabolism lasted two and one half times longer in 824(pGROE1) than in the wild type. Transcriptional analysis of 824(pGROE1) revealed increased expression of motility and chemotaxis genes and a decrease in the expression of the other major stress response genes. Decreased expression of the dnaKJ operon upon overexpression of groESL suggests that groESL functions as a modulator of the CIRCE regulon, which is shown here to include the hsp90 gene. Analysis of the plasmid control strain 824(pSOS95del) revealed complex host-plasmid interactions relative to the wild-type strain, resulting in prolonged biphasic growth and metabolism. Decreased expression of four DNA gyrases resulted in differential expression of many key primary metabolism genes. The ftsA and ftsZ genes were expressed at higher levels in 824(pSOS95del), revealing an altered cell division and sporulation pattern. Both transcriptional and Western analyses revealed elevated stress protein expression in the plasmid-carrying strain.
Stable gene replacement in barley by targeted double-strand break induction (2015)

Gene targeting is becoming an important tool for precision genome engineering in plants. During gene replacement, a variant of gene targeting, transformed DNA integrates into the genome by homologous recombination (HR) to replace resident sequences. We have analysed gene targeting in barley (Hordeum vulgare) using a model system based on double-strand break (DSB) induction by the meganuclease I-SceI and a transgenic, artificial target locus. In the plants we obtained, the donor construct was inserted at the target locus by homology-directed DNA integration in at least two transformants obtained in a single experiment and was stably inherited as a single Mendelian trait. Both events were produced by one-sided integration. Our data suggest that gene replacement can be achieved in barley with a frequency suitable for routine application. The use of a codon-optimized nuclease and co-transfer of the nuclease gene together with the donor construct are probably the components important for efficient gene targeting. Such an approach, employing the recently developed synthetic nucleases/nickases that allow DSB induction at almost any sequence of a genome of interest, sets the stage for precision genome engineering as a routine tool even for important crops such as barley.
Bandwidth Enhancement by Optical Modulation of Injection-Locked Semiconductor Lasers (2007)

We experimentally demonstrate optical modulation of injection-locked lasers, resulting in a resonant amplification of the transmitted signal. We enhance the 3-dB bandwidth of a 25-GHz electro-optic modulator to &gt;59 GHz and demonstrate the system’s tunability.
Characterization of a charge injection device camera system for spectrochemical measurements (1985)

An electronic camera system employing a CID-11B Charge Injection Device (CID) detector is described. Unique capabilities of this camera system, including destructive and nondestructive readout modes, signal-to-noise enhancement through multiple nondestructive readouts, and pseudo random pixel addressing are discussed. The performance characteristics related to spectrometric applications are presented. Parameters discussed include sensitivity, linearity, noise, dynamic range, blooming, pixel crosstalk, and spectral response. The CID appears to be uniquely qualified among imaging detectors to fulfill those requirements for an imaging spectroscopic detector presented at the beginning of this manuscript. The sensitivity of the CID-11B has been shown to be very good over a wide spectral range. The effective readout noise can be made to be very low, and the device is not susceptible to readout lag or blooming. In addition, this device has a highly linear response function and, when operated at cryogenic temperatures, exhibits virtually no thermal charge generation. While the CID-11B does suffer from a form of spatial pixel crosstalk, this effect is both understood and easily compensated for.
Dynamic MRI reveals that the magnitude of the ischemia‐related enhancement in skeletal muscle is age‐dependent (2003)

This study was designed to evaluate the influence of age on the dynamic contrast-enhanced MRI of ischemic tissue. A well-established model of peripheral arterial insufficiency (i.e., the rat hindlimb ischemia after removal of femoral artery) in different age groups (i.e., young, presenescent, and senescent rats) was studied. The analysis of the MR signal demonstrated a marked accumulation of a contrast agent (Gd-DTPA) in the ischemic leg (ischemia-related enhancement, IRE). IRE was an age-related event: 4-month-old rats showed a strong IRE while 12-month-old rats and 20-month old rats showed a significantly reduced IRE in comparison to young animals. Histological analysis of the ischemic muscles revealed that there was no evidence of significant necrosis of the muscle tissue but only a weak interstitial fibrosis; CD31-immunostaining revealed a preserved microcirculatory bed.
Hybrid Techniques for Aortic Arch Aneurysm Repair (2016)

Open repair of the aortic arch remains the gold standard for aortic aneurysms and dissections. However, in elderly patients with comorbidities, and in patients where prolonged cardiopulmonary bypass time and circulatory arrest may pose a significant risk, hybrid techniques in repairing the aortic arch have become quite attractive. Hybrid arch surgery includes a combination of endovascular and open surgery that allows surgeons to operate on the arch in a safe and expeditious manner with potential decrease in morbidity and mortality.
Ein Silicogermanat mit einem Si: Ge‐Verhältnis ⩾ 2 – ein neuartiger MFI‐Zeolith (1989)

Ein reiner Ge‐MFI‐Zeolith sollte nur schwer herstellbar sein. Dies ist die Schlußfolgerung einer Studie über die Möglichkeiten und Auswirkungen des Si/Ge‐Austauschs in Si‐MFI‐Zeolithen. Erhitzt man z.B. das Gemisch GeCl 4 ‐SiO 2 ‐HF‐0.5Pr 4 NBr‐8 CH 3 NH 2 ‐35 H 2 O 15 h auf 180°C, so resultiert ein Feststoff mit MFI‐Struktur, der nach Calcinieren die Zusammensetzung Si 63 Ge 33 O 192 hat. Der unerwartet hohe Ge‐Gehalt überschreitet alle bisher beobachteten Substitutionsgrade bei MFI‐Zeolithen.
Surface EMG Applications in Neurophysiology (2016)

This chapter focuses on the basics of surface electromyography (sEMG) and related methods for the study of human motor control and its adaptations. Recordings of voluntary sEMG provide partial information on the mechanisms involved in muscle activity. However, the combination of sEMG and methods based on electrically and magnetically evoked potentials allows stepping further in a comprehensive approach of movement strategies during tasks, and the influence of various factors such as etiology of cramps, fatigue, training, aging on such strategies. The recorded sEMG signal represents the electrical activity of numerous motor units. The chapter describes the basic methodology to record H-reflex and the relevant factors to consider when assessing its modulations. sEMG and evoked potentials provide relevant information on age-related changes within the muscle and the nervous system, as well as on the neural adjustments required to perform various motor tasks.
Cathodoluminescence spectroscopy study for non-destructive stress analysis of thermal silicon-oxide film (2012)

In this article, a technique for non-destructive stress analysis of thermal silicon-oxide (SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sub> ) film using cathodoluminescence (CL) spectroscopy is described. The uniaxial tensile tester which can be used in a scanning electron microscope (SEM) chamber was developed to apply tensile stress to the film specimen. CL spectra of SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sub> film were measured under various tensile stresses. The peak position linearly increased at 7.53×10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> eV/GPa with an increase in tensile stress. The peak intensity and half bandwidth changed with an increase in electron beam (EB) irradiation time period. Using Raman spectroscope and transmission electron microscope (TEM), it was found that EB irradiation produced silicon nanocrystals in SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sub> film. The nanocrystals as well as applied stress affected CL spectra.

Electronic Properties of a Graphene Device with Peptide Adsorption: Insight from Simulation (2013)

In this work, to explain doping behavior of single-layer graphene upon HSSYWYAFNNKT (P1) and HSSAAAAFNNKT (P1-3A) adsorption in field-effect transistors (GFETs), we applied a combined computational approach, whereby peptide adsorption was modeled by molecular dynamics simulations, and the lowest energy configuration was confirmed by density functional theory calculations. On the basis of the resulting structures of the hybrid materials, electronic structure and transport calculations were investigated. We demonstrate that π-π stacking of the aromatic residues and proximate peptide backbone to the graphene surface in P1 have a role in the p-doping. These results are consistent with our experimental observation of the GFET's p-doping even after a 24-h annealing procedure. Upon substitution of three of the aromatic residues to Ala in (P1-3A), a considerable decrease from p-doping is observed experimentally, demonstrating n-doping as compared to the nonadsorbed device, yet not explained based on the atomistic MD simulation structures. To gain a qualitative understanding of P1-3A's adsorption over a longer simulation time, which may differ from aromatic amino acid residues' swift anchoring on the surface, we analyzed equilibrated coarse-grain simulations performed for 500 ns. Desorption of the Ala residues from the surface was shown computationally, which could in turn affect charge transfer, yet a full explanation of the mechanism of n-doping will require elucidation of differences between various aromatic residues as dependent on peptide composition, and inclusion of effects of the substrate and environment, to be considered in future work.
The Uptake and Release of Polysulfur Cysteine Species by Cells: Physiological and Toxicological Implications (2019)

Hydropersulfides and related polysulfides have recently become topics of significant interest due to their physiological prevalence and proposed biological functions. Currently, examination of the effects of hydropersulfide treatment on cells is difficult due to their lack of inherent stability with respect to disproportionation. Herein, it is reported that the treatment of a variety of cell types with cysteine trisulfide (also known as thiocystine; Cys-SSS-Cys), results in an increase in intracellular hydropersulfide levels (e.g., cysteine hydropersulfide; Cys-SSH, and glutathione hydropersulfide; GSSH). Thus, Cys-SSS-Cys represents a possible pharmacological agent for examining the effects of hydropersulfides on cell function/viability. It has also been found that cells with increased intracellular hydropersulfide levels can export Cys-SSH into the extracellular media. Interestingly, the Cys-SSH is the major hydropersulfide exported by cells, although GSSH is the predominant intracellular species. The possible implications of cellular export are discussed.
On sketching matrix norms and the top singular vector (2014)

Sketching is a prominent algorithmic tool for processing large data. In this paper, we study the problem of sketching matrix norms. We consider two sketching models. The first is bilinear sketching, in which there is a distribution over pairs ofrxn matrices S and n x s matrices T such that for any fixed n x n matrix A, from S · A · T one can approximate ||A||p up to an approximation factor α ≥ 1 with constant probability, where ||A||p is a matrix norm. The second is general linear sketching, in which there is a distribution over linear maps L: Rn2 → Rk, such that for any fixed n x n matrix A, interpreting it as a vector in Rn2, from L(A) one can approximate ||A||p up to a factor α.We study some of the most frequently occurring matrix norms, which correspond to Schatten p-norms for p e {0, 1, 2, ∞}. The p-th Schatten norm of a rank-r matrix A is defined to be [EQUATION], where σ1,...,σr are the singular values of A. When p = 0, ||A||0 is defined to be the rank of A. The cases p = 1, 2, and ∞ correspond to the trace, Frobenius, and operator norms, respectively. For bilinear sketches we show:1. For p = ∞ any sketch must have r · s = O(n2/α4) dimensions. This matches an upper bound of Andoni and Nguyen (SODA, 2013), and implies one cannot approximate the top right singular vector v of A by a vector v' with ||v' -- v||2 ≤ 1/2 with r · s = o(n2)2. For p e {0, 1} and constant α, any sketch must have r · s ≥ n1-e dimensions, for arbitrarily small constant e > 0.3. For even integers p ≥ 2, we give a sketch with r · s = O(n2-4/pe-2) dimensions for obtaining a (1 + e)-approximation. This is optimal up to logarithmic factors, and is the first general subquadratic upper bound for sketching the Schatten norms.For general linear sketches our results, though not optimal, are qualitatively similar, showing that for p = ∞, k = Ω(n3/2/α4) and for p e {0, 1}, k = Ω(√n). These give separations in the sketching complexity of Schatten-p norms with the corresponding vector p-norms, and rule out a table lookup nearest-neighbor search for p = 1, making progress on a question of Andoni.
Interconnection of autonomous error-tolerant cells (2003)

In this paper we propose an interconnection scheme for the autonomous error-tolerant (AET) cell introduced in a paper by Valtonen et al. (2001). The objective here is to partition the system into identical, physically autonomous and highly configurable cells that can operate without outside control or synchronization. In billion transistor Network-on-Chip (NoC) circuits, an AET cell fabric could prove highly flexible and reliable, and allow for low replication costs, due to homogeneousity. However, many challenges persist before a useful system can be constructed: the need for (i) scalable long-distance communication-global bus wiring fits poorly into a homogeneous, symmetric fabric and limits scalability, (ii) flexible communication-cells in all directions, within a given range, should be accessible and (iii) self-synchronizing topologies, due to the absence of external synchronization; (iv) the interconnect scheme is to be implemented using near-future technology generations, and (v) the fabric should be efficient when constituting billions of cells.

Our results do not support the association between active discopathy and systemic bone fragility.
Quantitative encapsulation and retention of<sup>227</sup>Th and decay daughters in core–shell lanthanum phosphate nanoparticles (2020)

Targeted alpha therapy (TAT) offers great promise for treating recalcitrant tumors and micrometastatic cancers. One drawback of TAT is the potential damage to normal tissues and organs due to the relocation of decay daughters from the treatment site. The present study evaluates La(227Th)PO4 core (C) and core +2 shells (C2S) nanoparticles (NPs) as a delivery platform of 227Th to minimize systemic distribution of decay daughters, 223Ra and 211Pb. In vitro retention of decay daughters within La(227Th)PO4 C NPs was influenced by the concentration of reagents used during synthesis, in which the leakage of 223Ra was between 0.4 ± 0.2% and 20.3 ± 1.1% in deionized water. Deposition of two nonradioactive LaPO4 shells onto La(227Th)PO4 C NPs increased the retention of decay daughters to >99.75%. The toxicity of the nonradioactive LaPO4 C and C2S NP delivery platforms was examined in a mammalian breast cancer cell line, BT-474. No significant decrease in cell viability was observed for a monolayer of BT-474 cells for NP concentrations below 233.9 μg mL-1, however cell viability decreased below 60% when BT-474 spheroids were incubated with either LaPO4 C or C2S NPs at concentrations exceeding 29.2 μg mL-1. La(227Th)PO4 C2S NPs exhibit a high encapsulation and in vitro retention of radionuclides with limited contribution to cellular cytotoxicity for TAT applications.
Wave number of the coherent acoustic field in a medium with randomly distributed spheres (2009)

This paper presents an iterative method for numerically solving the secular equation obtained by Fikioris and Waterman for the effective wave number of the coherent acoustic field propagating in a medium with a random distribution of identical spherical scatterers. The method works both for the original equation derived by Fikioris and Waterman and for its generalization to the case of an arbitrary two-point correlation function in the positions of any two scatterers. An explicit solution up to second order in the density of scatterers is also obtained. In the point scatterer limit this solution is identical to that obtained by Lloyd and Berry which is considered to be the correct result for the effective wave number to second order in the density of scatterers in the point scatterer limit.
ON THE STUDIES OP MOLYBDENUM (VI) SORPTION ON TITANIUM PHOSPHATE 'S ION EXCHANGERS (1994)

Abstract Mo (VI) sorption on the inorganic Ion exchangers on amorphous titanium phosphate and hydrous titanium dioxide was studied. The influence of solution acidity, Mo(VI) concentration In a solution, P:T1 mole ratio in a sorbent and the presence of various anions In solution was Investigated. Mo-contalnlng lonites, as a result of a sorption process, were studied for the purification of water and Ringer’s solution, contamlned with Cs 137 Ions. Obtained sorbents were examined In solutions with some transition metals and alkaline earth metals. Also IR spectrophotometry studies were carried out. It was found that the process of Mo (VI) sorption on titanium hydroxophosphate occurred mainly according to an anion exchange mechanism and did not Improve upon the ion-exchange properties of the Initial lonites. Obtained caesium uptake characteristics demonstrated the absence of surface heteropolycompounds in titanium hydroxophosphate treated by Mo(VI)-compounds.
Draft genome sequences of five recent human uropathogenic<i>Escherichia coli</i>isolates (2013)

This study reports the release of draft genome sequences of five isolates of uropathogenic Escherichia coli (UPEC), isolated from patients suffering from uncomplicated cystitis in 2012 in Ann Arbor, Michigan. Phylogenetic analyses revealed that these strains belonged to E. coli phylogroups B2 and D and are closely related to known UPEC strains. Comparative genomic analysis revealed that more conserved proteins were shared between these recent isolates and UPEC strains causing cystitis than those causing pyelonephritis. Additional genomic comparisons identified that three isolates encode a type III secretion system (T3SS) and a putative T3SS effector gene cluster along with an invasin-like outer membrane protein. The presence of T3SS genes is a rare occurrence among UPEC strains. These genomes further substantiate the heterogeneity of the gene pool of UPEC and provide a foundation for comparative genomic studies using recent clinical isolates.
