Load shift protocol design in ATM-based VOD systems (2002)

Load shift is a basic operation for load balancing algorithms. In this paper, we study the load shift problem in an ATM-based distributed video-on-demand (VOD) system. Two different system configurations are considered for the load shift. One allows more than one video streams being active simultaneously from multiple video servers to a set-top box (STB), in which no-gap load shift is possible. The other one allows only one video stream between a STB and the VOD system. With respect to this case, two transport schemes are proposed: control with load shift (DRCLS) and constant rate control with load shift (CRCLS). For DRCLS, new water lines of the STB buffer have to be specified for flow control in cases of load shifts. For CRCLS, we compute the new feasible parameter set, which includes the required bandwidth, the minimal STB buffer size and the pre-download time. Finally, we compare the differences between DRCLS and DRCLS.
Surfing the implicit wave (2001)

Implicit learning was investigated in two experiments involving a complex motor task. Participants were required to balance on a stabilometer and to move the platform on which they were standing to match a constantly changing target position. Experiment 1 examined whether a segment (middle third) that was repeated on each trial would be learned without participants becoming aware of the repetitions (i.e., implicitly). The purpose of Experiment 2 was to determine the relative effectiveness of explicit versus implicit learning. Here, two identical segments were presented on each trial (first and last thirds), with participants only being informed that one segment (either first or last) was repeated. The acquisition results from both experiments indicated large improvements in performance across 4 days of practice, with performance on the repeated segments being generally superior to that on the non-repeated segment. On the retention tests on Day 5, errors on the repeated segment(s) were smaller than those on the random segment(s). Furthermore, in Experiment 2, the errors on the repeated-known segment, although smaller than those on the random segment, were larger than those on the repeated-unknown segment. Interview results indicated that participants were not consciously aware that a segment was repeated unless they were informed. These results suggest that implicit learning can occur for relatively complex motor tasks and that withholding information concerning the regularities is more beneficial than providing this information.
Stimulation of somatostatin expression in developing ciliary ganglion neurons by cells of the choroid layer (1991)

An important component of neuronal development is the matching of neurotransmitter expression with the appropriate target cell. We have examined how peptide transmitter expression is controlled in a simple model system, the avian ciliary ganglion (CG). This parasympathetic ganglion contains 2 distinct types of neurons: choroid neurons, which project to vasculature in the eye's choroid layer and use somatostatin as a co-transmitter with ACh, and ciliary neurons, which innervate the ciliary body and iris and use ACh but no known peptide co-transmitter. We have found that the earliest developmental stage in which neurons with somatostatinlike immunoreactivity (SOM-IR) are consistently found in vivo is stage 30 (embryonic day 6.5), a time shortly after the extension of neurites to targets in the eye's choroid layer. In cell culture, CG neurons expressed SOM-IR in co-culture with choroid cells, but not when cultured with striated muscle myotubes or with ganglion non-neuronal cells. No significant differences in neuronal survival or in ChAT activity were observed under these different co-culture conditions, which suggests that somatostatin expression is independently regulated. The stimulation of somatostatin expression was also specific in that other neuropeptides commonly found in autonomic neurons [neuropeptide Y (NPY), substance P (SP), vasoactive intestinal polypeptide (VIP)] were not induced in the presence of choroid cells. The ability to stimulate SOM-IR was not contact dependent because a macromolecule of greater than or equal to 10 kDa in choroid-conditioned medium (ChCM) was found to stimulate somatostatin expression in a dosage-dependent fashion. The somatostatin-stimulating activity induced SOM-IR in more than 90% of CG neurons, as well as in retrogradely labeled ciliary neurons, which would not normally express SOM-IR. Thus, the expression of somatostatin in cultured CG neurons is regulated by a macromolecule produced by cells in the choroid layer, a target normally innervated in vivo by CG neurons expressing somatostatin.

Inhibitory Effects of Korean Red Ginseng and Its Genuine Constituents Ginsenosides Rg3, Rf, and Rh2 in Mouse Passive Cutaneous Anaphylaxis Reaction and Contact Dermatitis Models (2006)

The inhibitory effects of the Korean red ginseng (steamed root of Panax ginseng C.A. MEYER, family Araliaceae) saponin fraction (KRGS) and its constituents ginsenosides Rg3, Rf, and Rh2 in mouse passive cutaneous anaphylaxis (PCA) and contact dermatitis models were measured. Orally administered KRGS and its genuine ginsenosides potently inhibited the PCA reaction induced by IgE. However, when these ginsenosides were intraperitoneally administered, ginsenoside Rh2 showed the most potent inhibition. The ginsenoside Rh2 also the most potently inhibited the beta-hexosaminidase release from RBL-2H3 cells induced by IgE with antigen. KRGS administered topically at a dose of 0.1% suppressed ear swelling in an oxazolone-induced mouse contact dermatitis model by 38.8%. Its constituents ginsenosides Rg3, Rf, and Rh2 at a concentration of 0.05% also potently suppressed mouse ear swelling by 47.5%, 34.8%, and 49.9% at 16 d, respectively. These ginsenosides also significantly reduced mRNA expression levels of cyclooxygenase (COX)-2, interleukin (IL)-1beta, tumor necrosis factor-alpha and interferon-gamma induced by oxazolone applied to mouse ears. However, the ginsenosides, except for ginsenoside Rh2, almost did not notably reduce IL-4 levels. The ginsenoside Rh2 also potently inhibited COX-2 and inducible NO synthetase protein expression in liphopolysaccharide-stimulated RAW264.7 cells. Based on these findings, KRGS and its ginsenosides are suggested to improve atopic and contact dermatitis by regulating expression of cytokines.
Abstract 19140: Targeted Disruption of Endothelial Specific Molecule (ESM)-1 Results in Atrioventricular Valve Malformations Leading to Cardiac Dysfunction (2012)

Background: Endothelial cell specific molecule-1 (ESM-1) or Endocan is a circulating dermatan sulphate proteoglycan secreted primarily by the vascular endothelium. Elevated levels of ESM-1 are observed in the plasma of patients during tumor progression and in inflammatory disorders like sepsis suggesting that it could be potential biomarker for endothelial activation or dysfunction. To date there have been no in vivo studies of ESM-1. In this study we investigated the in vivo functional role of ESM-1 by the targeted deletion of the gene in mice. Methods and Results: To determine the critical functions of ESM-1 in vivo, we generated a global ESM-1 knockout mouse by deletion of exon1 of the ESM-1 mouse gene. ESM-1 knockout mice were born at the normal Mendelian ratio but showed 50% perinatal mortality by postnatal day 3 (P3). Pathological analysis of mice that died at P2 revealed dilated atria engorged with blood and thrombi indicative of possible defect in cardiac contractility. Pulmonary and liver congestion were also observed in ESM-1 knockout mice. Furthermore, histopathological studies revealed structural abnormalities in atrioventricular valves (AV) with an ebstenoid tricuspid malformation and parachute mitral valve abnormality suggesting AV valve regurgitation in ESM-1 knockout mice. In contrast, the semilunar valves appeared normal. Fetal genes associated with cardiac stress response including atrial natriuretic peptide (Nppa), brain natriuretic pepetide (Nppb) and beta-myosin heavy chain (Myh7) were significantly up regulated in ESM1 knockout P2 hearts compared to controls. Conclusion: In conclusion, our findings demonstrate for the first time that targeted disruption of ESM-1 results in atrioventricular valve anomalies leading to cardiac dysfuction. Understanding the mechanisms and signaling networks through which ESM-1 regulates valve formation has implications in the field of congenital heart disease research
Synthesis and anthelmintic activity of 3'-benzoylurea derivatives of 6-phenyl-2,3,5,6-tetrahydroimidazo[2,1-b]thiazole (1991)

Reaction of 3-amino derivatives of the nematocides tetramisole and levamisole with variously substituted benzoylisocyanates gave a series of benzoylureas I which were tested for activity against helminths and ectoparasites. Compounds bearing 2,6-difluoro and 4-trifluoromethyl substituents had potent nematocidal activity in both mice and sheep. No antiectoparasitic activity was observed.

Implication of prostaglandin receptors in the accumulation of osteoprotegerin in human osteoblast cultures. (2006)

Our results show that activation of EP4 or DP receptors decreased the accumulation of OPG in supernatants of osteoblasts in culture, and suggest that these receptors could be interesting pharmacological targets in bone diseases. They also demonstrate important differences between primary osteoblasts and immortalized cell lines, both in the distribution and in the effects mediated by prostaglandin receptors.
Parametric chirp and 20-fold compression of pulses from a quasi-cw picosecond optical parametric oscillator (1985)

A linear chirp was observed for phase-conjugate picosecond pulses from a resonator-type optical parametric oscillator based on an LiNbO3 crystal pumped by the second harmonic of a YAG:Nd3+ laser with active mode locking and switching at repetition frequencies up to 10 kHz. A 20-fold compression of the parametric oscillator pulses to 2.5 psec was achieved.
The Early Activation Marker CD69 Regulates the Expression of Chemokines and CD4 T Cell Accumulation in Intestine (2013)

Migration of naïve and activated lymphocytes is regulated by the expression of various molecules such as chemokine receptors and ligands. CD69, the early activation marker of C-type lectin domain family, is also shown to regulate the lymphocyte migration by affecting their egress from the thymus and secondary lymphoid organs. Here, we aimed to investigate the role of CD69 in accumulation of CD4 T cells in intestine using murine models of inflammatory bowel disease. We found that genetic deletion of CD69 in mice increases the expression of the chemokines CCL-1, CXCL-10 and CCL-19 in CD4(+) T cells and/or CD4(-) cells. Efficient in vitro migration of CD69-deficient CD4 T cells toward the chemokine stimuli was the result of increased expression and/or affinity of chemokine receptors. In vivo CD69(-/-) CD4 T cells accumulate in the intestine in higher numbers than B6 CD4 T cells as observed in competitive homing assay, dextran sodium sulphate (DSS)-induced colitis and antigen-specific transfer colitis. In DSS colitis CD69(-/-) CD4 T cell accumulation in colonic lamina propria (cLP) was associated with increased expression of CCL-1, CXCL-10 and CCL-19 genes. Furthermore, treatment of DSS-administrated CD69(-/-) mice with the mixture of CCL-1, CXCL-10 and CCL-19 neutralizing Abs significantly decreased the histopathological signs of colitis. Transfer of OT-II×CD69(-/-) CD45RB(high) CD4 T cells into RAG(-/-) hosts induced CD4 T cell accumulation in cLP. This study showed CD69 as negative regulator of inflammatory responses in intestine as it decreases the expression of chemotactic receptors and ligands and reduces the accumulation of CD4 T cells in cLP during colitis.
Fanconi syndrome in lymphoma patients: report of the first case series (2010)

Patients with lymphoma require careful monitoring for features of FS; lymphoma should also be added to the spectrum of disorders associated to FS. Prospective studies are needed to ascertain the implication of HTLV1 in the genesis of FS.
Activity of T-1106 in a Hamster Model of Yellow Fever Virus Infection (2007)

Yellow fever virus (YFV) causes 30,000 deaths worldwide, despite the availability of a vaccine. There are no approved antiviral therapies for the treatment of YFV disease in humans, and, therefore, these studies were designed to investigate the anti-YFV properties of T-1106, a substituted pyrazine, in a hamster model of YFV disease. Intraperitoneal (i.p.) treatment with 100 mg/kg of body weight/day of T-1106 starting 4 h prior to virus inoculation and continuing twice daily through 7 days post-virus inoculation (dpi) resulted in significantly improved survival, alanine aminotransferase levels in the serum, weight gain, and mean day to death. Virus titer in the liver at 4 dpi was significantly reduced in treated animals, as determined by both quantitative real-time PCR and infectious cell culture assay. No toxicity (weight loss or mortality) was observed at a dose of 100 mg/kg/day in sham-infected control animals. The observed minimal effective dose of T-1106 was 32 mg/kg/day administered either by oral or i.p. treatment. Therapeutic treatment was effective in significantly improving survival when T-1106 was administered beginning as late as 4 days after virus challenge with twice-daily treatment for 8 days at a dose of 100 mg/kg/day. With favorable safety, bioavailability, and postviral challenge treatment efficacy, T-1106 was effective in the treatment of disease in hamsters infected with YFV and should be further studied for potential use as a therapy for human YFV disease.

Effect of BaO Morphology on NO<sub><i>x</i></sub> Abatement: NO<sub>2</sub> Interaction with Unsupported and γ-Al<sub>2</sub>O<sub>3</sub>-Supported BaO (2008)

First-principles density functional theory calculations have been applied to study NO2 interaction with BaO in various morphologies, including extended BaO surfaces as well as unsupported and γ-Al2O3-supported BaO clusters. Adsorption of NO2 over BaO of different morphologies studied with the same method allowed a direct comparison of adsorption structures and energetics. In comparison with the flat BaO(100) surface, the presence of the low-coordinated sites on the small BaO clusters and at the edge of the stepped BaO(310) surface not only strengthens the binding of NO2 at these sites but also creates new NO2 binding modes. The adsorption of NO2 at the accessible edge oxygen sites on the BaO clusters and stepped BaO(310) surface led to the formation of a nitrate species with the new N−O (surface or cluster) bond length of 1.3−1.5 Å. Furthermore, BaO(310) created an adsorption configuration with two oxygen atoms of the adsorbed NO2 bridging the step-edge and terrace Ba sites. This adsorption configuration has an adsorption energy of 1.39 eV and cannot be formed on BaO(100). The nonstoichiometric clusters and defective surfaces with either O or Ba vacancies exhibit much stronger affinity toward NO2, up to 4.09 eV for NO2 adsorption at the edge oxygen site of Ba14O13. NO2 prefers interacting with the nucleophilic substrate (O deficient) through its O atoms in an O-down configuration. Consequently, the adsorbed NO2 molecule gains partial electronic charge from the substrate, forming a NO2δ− species. On the other hand, the NO2 interacts with the electrophilic substrate (Ba deficient) by sharing its lone pair electrons on the N atom with a surface O site which resulted in a NO3δ− species. Furthermore, the synergistic effect of γ-Al2O3 and BaO toward NO2 adsorption reported previously (Cheng, L.; Ge, Q. Surf. Sci. 2007, 601, L65) was confirmed with a larger γ-Al2O3 surface unit cell that isolates the supported BaO cluster from its periodic images. The synergistic effect was attributed to the enhanced basicity and acidity of the supported BaO cluster and the γ-Al2O3 surface, respectively.

Where, What, Whether: Multi-modal Learning Meets Pedestrian Detection (2020)

Pedestrian detection benefits greatly from deep convolutional neural networks (CNNs). However, it is inherently hard for CNNs to handle situations in the presence of occlusion and scale variation. In this paper, we propose W$^3$Net, which attempts to address above challenges by decomposing the pedestrian detection task into \textbf{\textit{W}}here, \textbf{\textit{W}}hat and \textbf{\textit{W}}hether problem directing against pedestrian localization, scale prediction and classification correspondingly. Specifically, for a pedestrian instance, we formulate its feature by three steps. i) We generate a bird view map, which is naturally free from occlusion issues, and scan all points on it to look for suitable locations for each pedestrian instance. ii) Instead of utilizing pre-fixed anchors, we model the interdependency between depth and scale aiming at generating depth-guided scales at different locations for better matching instances of different sizes. iii) We learn a latent vector shared by both visual and corpus space, by which false positives with similar vertical structure but lacking human partial features would be filtered out. We achieve state-of-the-art results on widely used datasets (Citypersons and Caltech). In particular. when evaluating on heavy occlusion subset, our results reduce MR$^{-2}$ from 49.3$\%$ to 18.7$\%$ on Citypersons, and from 45.18$\%$ to 28.33$\%$ on Caltech.

Experimental results on gridded arrays of field emission tips (2003)

The results of experiments on gridded arrays of both dry-etched niobium and wet-etched silicon field emission tips are reported. The niobium results are the first to be reported for field emission from emitters fabricated in sputtered metal layers by reactive ion etching. Both I-V measurements and electron emission spectra are presented. It is found that emission occurred from only a small fraction of the available surface area, which is consistent with previous results for emission from tips fabricated by evaporating metal through the grid aperture. Spectroscopic measurements on the silicon tips revealed that the emission originated from several electronvolts below the Fermi energy in the emitters and that the linewidth is narrow with Delta E=0.28 eV full width at half maximum.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
