Olive-sided Flycatchers in southeastern Brazil.-The Olive-sided Flycatcher (Contopus borealis) winters principally in the highlands of Central America and the Andes, with occasional birds in the lowlands to Amazonian Brazil (A.O.U.Checklist of North American Birds, 6th edition, 1983, plus observations of Willis and Stotz near Manaus and of Stotz, 10 Oct. 1987, at Colonia Apiau, Roraima, 2"39' N, 61"12' W).On 27 Nov. 1983, Snow saw an Olive-sided Flycatcher at the Boractia Biological Station (23"38' S, 45' 5 1' W) of the Univ.Sfo Paulo, at 850 m elevation in the Serra do Mar of Slo Paulo State, southeastern Brazil.On 10 Nov. 1987, Stotz encountered possibly the same bird at the station, and on 5 Jan. 1991 he found a bird about 4 km away.Willis encountered a bird at a forest overlook at 800 m (24"17' S, 48"26' W) near Intervales, in cloud forests of the similar coastal range of the Serra do Paranapiacaba, on 14 Feb. and 3-4 March 1987.Parker found two separate birds at 1200 and 1400 m in Itatiaia National Park, Serra da Mantiqueira, in neighboring Rio de Janeiro State (30 Nov.-2 Dec. 1986 and 30 Nov., respectively).Willis and students encountered another bird atop a small eucalyptus line in a forested valley just east of the Serra do Mar on 16 March 1990 (Ubatuba Agricultural Experiment Station, 100 m, 23"25' S, 45008' W).On 18 March, yet another was located in the next valley, 5 km northeast, atop cecropias of a cocoa plantation with forest canopy (Fazenda Capricomio, 100 m, 23"23' S, 45"05' W).Like the other birds encountered, these called "pip pip pip" frequently and sallied conspicuously from the tops of exposed branches at forest edges or over mountain escarpments.SIo Paulo and Rio de Janeiro have been well studied ornithologically since the early 1900s.Collectors such as von Ihering, the Garbes, the Limas, Pinto, Sick, A.

WLC11-2: Propagation Channel Characteristics for Peer-to-Peer Multiple Antenna Systems at 300 MHz (2006)

This paper presents results from the first double-directional measurements of the multiple-input multiple-output (MIMO) peer-to-peer radio channel in the 300 MHz frequency range. The measurements were performed with vertically polarized circular antenna arrays mounted on cars driving along a route in a semi rural and sub-urban environment. We evaluate the measurements with a high resolution algorithm, thus obtaining a wideband, double-directional characterization of the propagation channel. The delay- and directional spread, as well as the small-scale fading statistics are analyzed along the measurement routes and major scatterers are identified. The measurements, performed with low antennas heights, show high angular spreads, caused by reflections from trees and buildings and by diffractions over terrain irregularities. We further observe multiple clusters in both the delay and angular domains. The large spreads in these domains indicate a high degree of available diversity, and rich multipath in the considered environment.
Two-dimensional electron-gas AlN/GaN heterostructures with extremely thin AlN barriers (2000)

Plasma-assisted molecular-beam epitaxy is used to grow a set of two-dimensional electron-gas AlN/GaN structures with AlN barrier thicknesses varied between 24 and 50 Å. The density of the two-dimensional electron gas formed at the GaN/AlN interface increases from 1.51×1013 cm−2 for the AlN barrier width of 24 Å to 3.65×1013 cm−2 for the AlN barrier width of 49 Å. The increase in the electron sheet density is accompanied by a decrease in electron mobility related to tensile strain relaxation and enhanced interface roughness scattering. It is shown that room-temperature sheet resistances below 200 Ω/□ can be achieved in AlN/GaN high electron mobility transistor structures with 35–45 Å AlN barriers.
Basic first aid and life support: are the schools prepared? a descriptive study (2021)

Background: First aid is the immediate assistance provided to a sick or injured. Children spend most of their daytime in schools and are at greater risk of accidents and injuries. National disaster management guidelines 2016 recommends that school teachers and students be trained in first aid and basic life support (BLS). This study was undertaken in schools to assess the awareness of high school students and teachers about first aid and BLS, accompanied by demonstration and hands-on training.Methods: This was a descriptive cross sectional study. All students of class 11th and 12th and teachers of three cantonment schools in New Delhi were included. Knowledge was assessed using a questionnaire comprising 20 multiple choice questions. 377 questionnaires were analyzed.Results: Mean knowledge score=10.96, SD=2.87. 67.6% participants had a score &lt;12 (60%), 29 (7.7%) had good knowledge, 214 (56.8%) average (11-15) and 107 (35.5%) poor (≤10).Conclusions: There was low level of awareness about correct first aid and BLS. First aid training should be incorporated as a part of school curriculum. Repeated reinforcement of knowledge and skills is essential.
.beta.-Carotene as a probe of lipid domains of reconstituted human plasma low-density lipoprotein: induced circular dichroism (1980)

Mixtures of neutral lipids containing cholesteryl esters and beta-carotene were used to reconstitute the lipid core of heptane-extracted low-density lipoproteins (LDL). The resulting preparations of reconstituted LDL, referred to as r-[cholesteryl ester + beta-carotene]LDL, exhibited temperature-dependent circular dichroism (CD) in the visible region similar to that of native LDL. Since beta-carotene lacks intrinsic optical asymmetry, the observed CD must be induced by environmental constraint. LDL reconstituted with cholesteryl oleate, cholesteryl linoleate, or cholesteryl linolenate in the presence of beta-carotene exhibited thermotropic transitions at approximately 40, 35, and 30 degrees C, respectively. These temperatures are similar to the liquid-crystalline to isotropic liquid phase transition temperatures observed for pure cholesteryl ester model systems. The addition of triolein to r-[cholesteryl linoleate + beta-carotene]LDL lowered the transition temperature and decreased the specific ellipticity of the visible CD bands. When triolein accounted for 70% or more of the total neutral lipid content of r-[cholesteryl linoleate + triolein + beta-carotene]LDL, specific ellipticity was zero. The addition of low levels of unesterified cholesterol to r-[cholesteryl linoleate + beta-carotene]LDL did not alter the transition temperature but did reduce the specific ellipticity by 40%. The current data indicate that the organization of the core of neutral lipids in reconstituted LDL resembles that of native LDL with respect to environmental constraint on the beta-carotene molecule and that the helicity of the protein moiety resembles that of native LDL. In addition, the data are consistent with the possibility that the core cholesteryl esters of reconstituted LDL undergo phase transitions similar to their transitions in the free state.
Mixed structural-functional path delay test generation and compaction (2013)

This work considers the use of a mixed structural-functional approach to path delay fault test generation and compaction. K Longest Paths per Gate (KLPG) are generated using structural information and filtered using direct implications and heuristics. These paths are then justified using Boolean satisfiability (SAT) algorithms. The paths are dynamically compacted into test patterns, using structural information to identify most conflicts, before final checking with SAT. Advanced SAT algorithms based on structural information of the circuit are investigated to improve SAT performance. Compared to structural-only approaches, the combined structural-functional approach achieves a better test compaction ratio in less CPU time on benchmark circuits. The improvement is more apparent when generating pseudo functional KLPG tests.
Serum Levels of Soluble CD40 Ligand and Neopterin in HIV Coinfected Asymptomatic and Symptomatic Visceral Leishmaniasis Patients (2018)

Human Immunodeficiency Virus (HIV) co-infection drastically increases the risk of developing overt visceral leishmaniasis (VL). The asymptomatic <i>Leishmania</i> infection window constitutes an opportunity to identify those HIV patients at highest risk by defining early markers associated with disease susceptibility or resistance. As intracellular parasite killing is essential, we investigated whether serum markers of macrophage activation were notably affected in HIV patients with an asymptomatic <i>Leishmania</i> infection or overt visceral leishmaniasis disease. Serum levels of soluble CD40 ligand and neopterin were assessed in 24 active VL-HIV patients, 35 HIV patients with asymptomatic <i>Leishmania</i> infection and 35 HIV endemic controls. All patients were recruited in <i>L. donovani</i> endemic regions of North-West Ethiopia. The serum levels of sCD40L and neopterin significantly decreased and increased in HIV patients with active VL compared to HIV patients with asymptomatic <i>Leishmania</i> infection, respectively. No statistically significant differences could be detected in neopterin and sCD40L levels between <i>Leishmania</i> asymptomatically infected HIV patients and endemic HIV control patients. However, an inverse trend, between <i>Leishmania</i> antibody positivity or VL development and neopterin levels could be seen. The CD4+ T-cell count was inversely correlated with serum neopterin levels, but not with sCD40L levels. Our results in HIV coinfected patients, correspond with the postulated protective role of sCD40L in VL and underline the importance of the CD40-CD40L pathway in resistance against the parasite. Neopterin levels suggest an increased macrophage activation upon infection and could have a value in clinical algorithms to, although non-specifically, improve prediction of VL development in HIV patients with asymptomatic <i>Leishmania</i> infection.
Abstract 366: Enhanced tumor detection of fluoroscence laparoscopy improves laparoscopic resection of primary pancreatic cancer in mouse models (2012)

Abstract The aim of this study was to evaluate the utility of fluorescence laparoscopy for resection of primary pancreatic cancer. Orthotopic mouse models of human pancreatic cancer were established with the brightly-fluorescent BxPC-3 RFP human pancreatic cancer cell line. Two weeks after implantation, mice were randomized to undergo either bright light laparoscopic resection (BLR) or fluorescence-guided laparoscopic resection (FLR). Fluorescence laparoscopy (FL) was performed with a Stryker L9000 LED light source 24 hours after tail vein injection of CEA antibodies conjugated to Alexa 488. Bright light laparoscopy (BL) was performed with a Stryker X8000 xenon light source. Pre- and postoperative images were taken with the Olympus OV-100 Small Animal Imaging System to assess completeness of resection. Postoperatively, whole body images were obtained to assess for recurrence and follow tumor progression. All resected tumors were collected for histologic review. Fluorescence laparoscopy with a 495-nm emission filter and an LED light source enabled real-time identification and localization of the brightly-fluorescent BxPC-3 RFP tumor additionally labeled with anti-CEA-Alexa 488. The combination of red and green fluorophores optimized the fluorescence signal of the tumor thereby enabling accurate distinction of tumor margins from normal surrounding tissue without compromising background illumination. Furthermore, adequate visualization of surrounding structures enabled surgical navigation for resection of primary pancreatic tumor. Tumor was more readily detected and resected under fluorescence guidance than under standard bright light. In addition, sub-millimeter lesions within the pancreas that were undetected by bright light laparoscopy were easily identified and resected by fluorescence laparoscopy. This study demonstrates the capabilities of laparoscopic fluorescence-guided surgery of primary pancreatic cancer. The optimal combination of fluorophores with the use of an LED light source enhanced the fluorescence tumor-to-background ratio while permitting enough light leakage for background illumination for surgical navigation.

The architecture and recognition algorithm in Haibao perceptual development robot (2010)

Haibao, demonstrated at World Expo 2010, has dense LED lights all over its body for flexible changes of its facial expressions, clothes and display of other graphic information. Its visual capability is performed by a Where-What Network (WWN), modeling the dorsal and ventral streams of the biological visual cortex. It is adapted from WWN-3, the first series of visual detection and recognition algorithms that are capable of detecting and recognizing a general object or pattern from complex backgrounds. In this paper, key issues in the architecture, detection and recognition algorithm, and the robot body are discussed with some results of experiments.
Risk-Adapted Melphalan and Stem Cell Transplant for Systemic Light Chain Amyloidosis: A Single Institution Experience (2013)

High dose melphalan (MEL) is a standard treatment for eligible patients with AL, a disease in which hematologic response is a key determinant of survival. With the advent of novel agents the role of SCT for patients with AL is being questioned, especially given safety concerns. Yet with appropriate patient selection and the use of risk-adapted SCT (RA-SCT), treatment-related mortality (TRM) improved. (Br J Haem 2007;139:224; Bone Marrow Transplantation 2011; 46:970) Beginning in 2002, we showed in 2 consecutive phase II trials that following RA-SCT patients can safely receive consolidation with thalidomide and dexamethasone (TD) or bortezomib and D (BD), with the goal of improving hematologic response thereby extending overall survival (OS). (Br J Haem 2007;139:224; Amyloid 2010;17:80a) Consolidation was administered for patients achieving less than a complete response (CR). We now describe the outcomes of all patients with AL who underwent RA-SCT at Memorial Sloan-Kettering Cancer Center (MSKCC) since the year 2000. We performed a retrospective study to assess the OS of all patients who underwent SCT for a diagnosis of AL confirmed at MSKCC. Patients who had >2 major organs involved, NYHA class III or greater CHF, critical arrhythmias or cardiac syncope were ineligible for SCT. OS was calculated from transplant to date of death or last follow up. Median survival was estimated by Kaplan Meier methods. Log-rank test was used to determine whether survival functions differed by covariates of interest. Cumulative incidence function was used to estimate the incidence of cause-specific mortality. A total of 151 patients underwent RA-SCT between February 2000 and June 2011; three lost to follow-up are excluded from this analysis. Of the remaining 148 patients 21%, 52% and 34% received RA-SCT at 100, 140 and 200mg/m2 of melphalan respectively based on age, renal function and cardiac involvement.(Blood 2002; 99: 4276) Five patients died within 100 days of SCT (TRM 3.4%). At a median follow up of 6.7 years, the median OS for all patients is 11.1 years (95% CI, 7.32 - not reached-NR) (Figure 1), and for patients who received MEL 100, 140 or 200 is 4.4 (95% CI, 2.7 – 6.3), NR and 11 years (95% CI, 8.2 – NR) respectively (P ≤ 0.01). Cumulative incidence of disease related mortality at 2 years is 5.5%, and subsequently the rate of death from other causes exceeds that due to AL. RA-SCT for appropriately selected patients is safe and is associated with excellent long-term survival. Consolidation with novel agents may improve survival following RA-SCT and likely accounts for the similar OS seen in patients who received MEL 140 and 200. In the era of novel agents available for post-SCT consolidation, RA-SCT is an effective and important initial treatment for patients with AL.
Generation of femtosecond pulses through second-harmonic compression of the output of a Nd:YAG laser (1995)

We report a greater than 20-fold compression during second-harmonic generation from an active–passive mode-locked Nd:YAG laser controlled by passive negative feedback. A compression ratio of 32 times is achieved in the beam center, resulting in a pulse duration of 360 fs.
Evaluation of Electrode and Solution Area-Based Resistances Enables Quantitative Comparisons of Factors Impacting Microbial Fuel Cell Performance (2019)

Direct comparisons of microbial fuel cells based on maximum power densities are hindered by different reactor and electrode sizes, solution conductivities, and materials. We propose an alternative method here, the electrode potential slope (EPS) analysis, to enable quantitative comparisons based on anode and cathode area-based resistances and operating potentials. Using EPS analysis, the brush anode resistance ( R<sub>An</sub> = 10.6 ± 0.5 mΩ m<sup>2</sup>) was shown to be 28% lower than the resistance of a 70% porosity diffusion layer (70% DL) cathode ( R<sub>Cat</sub> = 14.8 ± 0.9 mΩ m<sup>2</sup>) and 24% lower than the solution resistance ( R<sub>Ω</sub> = 14 mΩ m<sup>2</sup>) (acetate in a 50 mM phosphate buffer solution). Using a less porous cathode (30% DL) did not impact the cathode resistance but did reduce the cathode performance due to a lower operating potential. With low-conductivity domestic wastewater ( R<sub>Ω</sub> = 87 mΩ m<sup>2</sup>), both electrodes had higher resistances [ R<sub>An</sub> = 75 ± 9 mΩ m<sup>2</sup>, and R<sub>Cat</sub> = 54 ± 7 mΩ m<sup>2</sup> (70% DL)]. Our analysis of the literature using EPS analysis shows how electrode resistances can easily be quantified to compare system performance when the electrode distances are changed or the sizes of the electrodes are different.
Nanoscale Spatiotemporal Diffusion Modes Measured by Simultaneous Confocal and Stimulated Emission Depletion Nanoscopy Imaging (2018)

The diffusion dynamics in the cellular plasma membrane provide crucial insights into molecular interactions, organization, and bioactivity. Beam-scanning fluorescence correlation spectroscopy combined with super-resolution stimulated emission depletion nanoscopy (scanning STED-FCS) measures such dynamics with high spatial and temporal resolution. It reveals nanoscale diffusion characteristics by measuring the molecular diffusion in conventional confocal mode and super-resolved STED mode sequentially for each pixel along the scanned line. However, to directly link the spatial and the temporal information, a method that simultaneously measures the diffusion in confocal and STED modes is needed. Here, to overcome this problem, we establish an advanced STED-FCS measurement method, line interleaved excitation scanning STED-FCS (LIESS-FCS), that discloses the molecular diffusion modes at different spatial positions with a single measurement. It relies on fast beam-scanning along a line with alternating laser illumination that yields, for each pixel, the apparent diffusion coefficients for two different observation spot sizes (conventional confocal and super-resolved STED). We demonstrate the potential of the LIESS-FCS approach with simulations and experiments on lipid diffusion in model and live cell plasma membranes. We also apply LIESS-FCS to investigate the spatiotemporal organization of glycosylphosphatidylinositol-anchored proteins in the plasma membrane of live cells, which, interestingly, show multiple diffusion modes at different spatial positions.
2D mm-wave imaging based on singular value decomposition (2019)

In this paper, we develop a systematic framework for two-dimensional mm-wave imaging, based on the singular value decomposition (SVD) of the Helmholtz wave equation under the Born approximation. We identify the degrees of freedom as a function of the geometry of the aperture and the scene, and provide insight into the eigenmodes identified by the SVD. For sparse arrays with number of elements smaller than the degrees of freedom, we propose, and experimentally demonstrate the efficacy of, an eigen-filtered pseudo-inverse algorithm which selects the eigenmodes being imaged.
Extra‐intestinal thrombosis in experimental colitis (2007)

Inflammatory bowel disease (IBD) is associated an increased risk for thromboembolism. While thrombosis is known to contribute to morbidity and mortality in IBD, it remains unclear whether this hypercoagulable state can be recapitulated in animal models of colitis. The objectives of this study were to determine whether murine colitis is associated with enhanced thrombus formation in an extra‐intestinal vascular bed, and whether genetic overexpression of the endothelial cell protein C receptor (ECPR) offers protection against the thrombus promoting effects of colitis. Intravital microscopy was used to monitor thrombus formation in arterioles and venules of the cremaster muscle in wild type (WT) and ECPR‐transgenic mice placed on 3 % dextran sodium sulfate (DSS) in drinking water for 6 days. Thrombus formation was induced using the light/dye endothelial injury model and quantified using the time of onset and completion (blood flow cessation) of the formed thrombus. Our results show that DSS colitis is also associated with an enhanced thrombotic response that is consistent with a pro‐coagulant state; this effect was largely manifested in arterioles but not in venules. Overexpression of ECPR significantly delayed thrombus formation. These findings indicate that extra‐intestinal thrombus formation is enhanced in experimental IBD and that ECPR affords protection against this response. (P01 DK43785)

Charge Transport in LDPE Nanocomposites Part I—Experimental Approach (2016)

This work presents results of bulk conductivity and surface potential decay measurements on low-density polyethylene and its nanocomposites filled with uncoated MgO and Al₂O₃, with the aim to highlight the effect of the nanofillers on charge transport processes. Material samples at various filler contents, up to 9 wt %, were prepared in the form of thin films. The performed measurements show a significant impact of the nanofillers on reduction of material's direct current (dc) conductivity. The investigations thus focused on the nanocomposites having the lowest dc conductivity. Various mechanisms of charge generation and transport in solids, including space charge limited current, Poole-Frenkel effect and Schottky injection, were utilized for examining the experimental results. The mobilities of charge carriers were deduced from the measured surface potential decay characteristics and were found to be at least two times lower for the nanocomposites. The temperature dependencies of the mobilities were compared for different materials.
