Using differential constraints to generate a 3D face model from stereo (2002)

We propose a way to incorporate a priori information in a 3D stereo reconstruction process from a pair of calibrated face images. A 3D mesh modeling the surface is iteratively deformed in order to minimize an energy function. Differential information about the object shape is used to generate an adaptive mesh that can fulfil the compacity and the accuracy requirements. Moreover in areas where the stereo information is not reliable enough to accurately recover the surface shape, because of inappropriate texture or bad lighting conditions, we incorporate geometric constraints related to the differential properties of the surface, that can be intuitive or refer to predefined geometric properties of the object to be reconstructed. They can be applied to scalar fields, such as curvature values, or structural features, such as crest lines. Therefore, we generate a 3D face model using computer vision techniques that is compact, accurate and consistent with the a priori knowledge about the underlying surface.
Dynamically tunable reflecting near-infrared bandpass filter based on a hybrid graphene–nanometallic structure (2020)

A dynamically tunable reflecting near-infrared bandpass filter based on a hybrid graphene–nanometallic structure is demonstrated by numerical simulation. The proposed filter is constructed by unit cells with a graphene monolayer embedded into the nanometallic grating structure. The gradual transition of the graphene monolayer from a very thin metal to dielectric plays the key role in tuning the reflection spectrum of the structure. Spectral analysis clearly shows a passband blueshift with increasing graphene Fermi energy. The filter parameters are investigated by varying graphene Fermi energy through external voltage gates. The modulation depth, center frequency, bandwidth, and quality factor of the filter could be tuned. We achieved stable modulation depth as high as 0.735, and a quality factor as high as 3.4. The center frequency can be tuned in a broad range from 210 to 230 THz and with bandwidth tuning from 60 to 95 THz. The effect of the nanogap size and environment refractive index is also numerically investigated. These results are very promising for future use and integration of the proposed filters as a key element of optical communication systems and infrared sensing.
Environmental research program for slagging fixed-bed coal gasification. Status report, November 1981 (1982)

A collaborative environmental research program to provide information needed to assess the health and environmental effects associated with large-scale coal gasification technology is being conducted by Argonne National Laboratory (ANL) and the Grand Forks Energy Technology Center (GFETC). The objectives are to: investigate the toxicology and chemical composition of coal gasification by-products as a function of process variables and coal feed; compare the characteristics of isokinetic side-stream samples with those of process stream samples; identify the types of compounds responsible for toxicity; evaluate the chemical and toxicological effectiveness of various wastewater treatment operations; refine methodology for the collection and measurement of organic vapors and particulates in workplace air; and obtain preliminary data on workplace air quality. So far the toxicities of a set of process stream samples (tar, oil, and gas liquor) and side-stream condensates from the GFETC gasifier have been measured in a battery of cellular screening tests for mutagenicity and cytotoxicity. Preliminary data on the effects of acute and chronic exposures of laboratory animals to process tar have been obtained. The process tar has been chemically fractionated and the distribution of mutagenicity and compound types among the fractions has been determined. Organic vapors and particulates collected at various times and locations in the gasifier building have been characterized.
Efficient reacquire and identify path planning over large areas (2014)

An important task in maritime search and inspection involves re-acquiring and identifying underwater objects by surveying the objects from multiple angles. Because of false contacts related to clutter on the sea floor, the objects are often detected in dramatically different densities in a given area. Previously developed methods to plan survey paths on groups of contacts led to efficient paths when the contacts occur in close proximity, but inefficient paths when the objects occur over large distances. We present a planning algorithm to generate an efficient path to survey objects from multiple angles that is independent of the density of the objects. The algorithm leverages the previously-developed algorithms for surveying objects from multiple directions, coupled with density-based spatial clustering of applications with noise (DBSCAN) clustering and ant colony optimization techniques.
Toxicity and Repellency of Potting Soil Treated with Bifenthrin and Tefluthrin to Red Imported Fire Ants (Hymenoptera: Formicidae) (1996)

The LCso and LCgo of bifenthrin in potting soil for female alates of tlw red impoded fire ant, SolellOpsis il/vieta Buren, were 1.1 and .5.2 ppm, respectively. For teAllthrin, the LC"o and LCgo were 8 ..5 and 19.0 ppm, respectively. These results may provide a basis for settin?; minimum residue levels for the enforcement of quarantine regulations. Pots filled \vith soil treated \vith either bifenthrin or teAuthrin at the label rate of 2.5 ppm were exposed to slllall colonies of S. illvicta without altemative nesting sites. After 48 h, 6% of the bifenthrintreated pots and 24% of the teAuthrin-treated pots were considered infested under quarantine standards. \Vhen exposure was lengthened to 2 wk, all pots were uninfested. Implications for the impOlted fire ant quarantine program are discussed.
Implantation of Mouse Embryonic Stem Cell-Derived Cardiac Progenitor Cells Preserves Function of Infarcted Murine Hearts (2010)

Stem cell transplantation holds great promise for the treatment of myocardial infarction injury. We recently described the embryonic stem cell-derived cardiac progenitor cells (CPCs) capable of differentiating into cardiomyocytes, vascular endothelium, and smooth muscle. In this study, we hypothesized that transplanted CPCs will preserve function of the infarcted heart by participating in both muscle replacement and neovascularization. Differentiated CPCs formed functional electromechanical junctions with cardiomyocytes in vitro and conducted action potentials over cm-scale distances. When transplanted into infarcted mouse hearts, CPCs engrafted long-term in the infarct zone and surrounding myocardium without causing teratomas or arrhythmias. The grafted cells differentiated into cross-striated cardiomyocytes forming gap junctions with the host cells, while also contributing to neovascularization. Serial echocardiography and pressure-volume catheterization demonstrated attenuated ventricular dilatation and preserved left ventricular fractional shortening, systolic and diastolic function. Our results demonstrate that CPCs can engraft, differentiate, and preserve the functional output of the infarcted heart.
13fJ/bit probing-resilient 250K PUF array with soft darkbit masking for 1.94% bit-error in 22nm tri-gate CMOS (2014)

A 250K probing-resilient PUF array with measured 2GHz operation and total energy consumption of 13fJ/bit at 0.9V, 25°C is fabricated in 22nm tri-gate CMOS. Hybrid PUF circuit with integrated load modulation and run-time soft dark-bit mask generation enables identification of unstable PUF bits with 100% accuracy, eliminating the need for multiple voltage/temperature characterization while also reducing bit-error down to 1.94%. Transient behavior of the hybrid PUF cell, along with the use of balanced local clock routing improves resiliency to invasive power-up probing attacks by 75%.
Immigration and Preferences for Greater Law Enforcement Spending in Rich Democracies (2019)

Immigration to rich democracies grew substantially in the 1990s and 2000s. We investigate whether the rise of immigration influenced the novel and salient outcome of preferences for greater law enforcement spending. We propose that these preferences are consequential for policymaking, reflect popular demand for punitive social control, and represent micro-level preferences underlying the politics of criminal justice. Motivated by literatures on criminal justice politics, minority threat, and the fear of crime, we examine whether stocks and flows of immigration influence individual-level preferences for greater law enforcement spending. Using International Social Survey Programme (ISSP) data, we analyze between-country variation with multi-level models of 25 countries in 2006, and within-country variation with differences-in-differences (DD) models of 16 countries with available data in both 1996 and 2006. Both multilevel and DD models show that flows of immigration increase preferences for greater law enforcement spending. Indeed, the coefficients for immigration flows are larger than or comparable in magnitude to the coefficients for any other variable, and are robust net of homicide rates and police officers per 100,000. By contrast, the stock of immigrants is not robustly associated with preferences. The results demonstrate that rising immigration contributed to increasing public support for greater law enforcement spending.

A New High-Efficiency Single-Phase Transformerless PV Inverter Topology (2009)

There is a strong trend in the photovoltaic inverter technology to use transformerless topologies in order to acquire higher efficiencies combining with very low ground leakage current. In this paper, a new topology, based on the H-bridge with a new ac bypass circuit consisting of a diode rectifier and a switch with clamping to the dc midpoint, is proposed. The topology is simulated and experimentally validated, and a comparison with other existing topologies is performed. High conversion efficiency and low leakage current are demonstrated.

Pollution Gradients and Chemical Characterization of Particulate Matter from Vehicular Traffic near Major Roadways: Results from the 2009 Queens College Air Quality Study in NYC (2012)

We present measurements of traffic-related pollutants made near the Long Island Expressway (LIE, I-495), in Queens, New York. The Aerodyne Research Inc. (ARI) mobile laboratory (AML) was deployed to map spatial and temporal gradients of gas-phase species and particulate matter (PM) associated with vehicular exhaust in the residential areas near the LIE. We observe that pollutant levels build up during the early morning hours under stable boundary layer conditions yet fall off quickly within 150 m downwind of the highway. An ARI soot particle aerosol mass spectrometer (SP-AMS) provided measurements of the size-resolved chemical composition of refractory black carbon (rBC) and the associated coating species. The average size distribution of the traffic related PM is characterized by a rBC mode centered at ∼100 nm in vacuum aerodynamic diameter, D va (rBC mass fraction ∼50%). A second rBC mode (rBC mass fraction ∼5%) more heavily coated with organic material is also observed at D va ∼500 nm. Positive matrix factorization (PMF) analyses of the traffic-related PM indicates that rBC is mostly associated with hydrocarbon-like organic (HOA) PM. These results are discussed in the context of chemically resolved size distributions and PMF analysis results performed on the SP-AMS stationary data collected at the Queens College site. Finally, we report emission indices (EI) for both fleet-average conditions and single vehicles, including several New York City Metropolitan Transit Authority (MTA) buses, sampled by the AML in "chase" mode during the study.

Applications of Electromyography in the Throwing Shoulder (1996)

In the complex movement that makes up the baseball pitch, shoulder motion is a single link in an orderly chain of events. It can be argued, though, that herein lies the weakest link and by far the most commonly affected cog in the spectrum of overuse injuries in pitchers. Just why the shoulder receives the brunt of the stress has been the subject of numerous studies in the past several years. The tools of choice in many of these articles have been electromyography and high speed photography which have enabled researchers to study dynamically the phases of the pitch and the sequential firing of the muscles involved. With this information and the knowledge gained from studies looking at muscle activity during specific exercises, the clinician should be able to tailor a rehabilitation program that meets the needs of his or her patient. What has been learned from these articles as applied to the biomechanics of the pitch and the rehabilitation of the athlete who throws and the limitations of this form of study need to be clarified.
Expression of delta-like ligand 4 (Dll4) and markers of hypoxia in colon cancer (2009)

Endothelial expression of Dll4 is not a prognostic factor, but is significantly associated with VEGF. Assessing endothelial Dll4 expression may be critical in predicting response to anti-VEGF therapies.
Rate-Splitting Multiple Access for Coordinated Multi-Point Joint Transmission (2019)

As a promising downlink multiple access scheme, Rate-Splitting Multiple Access (RSMA) has been shown to achieve superior spectral and energy efficiencies compared with SpaceDivision Multiple Access (SDMA) and Non-Orthogonal Multiple Access (NOMA) in downlink single-cell systems. By relying on linearly precoded rate-splitting at the transmitter and successive interference cancellation at the receivers, RSMA has the capability of partially decoding the interference and partially treating the interference as noise, and therefore copes with a wide range of user deployments and network loads. In this work, we further study RSMA in downlink Coordinated Multi-Point (CoMP) Joint Transmission (JT) networks by investigating the optimal beamformer design to maximize the Weighted Sum-Rate (WSR) of all users subject to individual Quality of Service (QoS) rate constraints and per base station power constraints. Numerical results show that, in CoMP JT, RSMA achieves significant WSR improvement over SDMA and NOMA in a wide range of inter-user and inter-cell channel strength disparities. Specifically, SDMA (resp. NOMA) is more suited to deployments with little (resp. large) inter-user channel strength disparity and large (resp. little) inter-cell channel disparity, while RSMA is suited to any deployment. We conclude that RSMA provides rate, robustness and QoS enhancements over SDMA and NOMA in CoMP JT networks.
Real-Time Growth Kinetics Measuring Hormone Mimicry for ToxCast Chemicals in T-47D Human Ductal Carcinoma Cells (2013)

High-throughput screening (HTS) assays capable of profiling thousands of environmentally relevant chemicals for in vitro biological activity provide useful information on the potential for disrupting endocrine pathways. Disruption of the estrogen signaling pathway has been implicated in a variety of adverse health effects including impaired development, reproduction, and carcinogenesis. The estrogen-responsive human mammary ductal carcinoma cell line T-47D was exposed to 1815 ToxCast chemicals comprising pesticides, industrial chemicals, pharmaceuticals, personal care products, cosmetics, food ingredients, and other chemicals with known or suspected human exposure potential. Cell growth kinetics were evaluated using real-time cell electronic sensing. T-47D cells were exposed to eight concentrations (0.006-100 μM), and measurements of cellular impedance were repeatedly recorded for 105 h. Chemical effects were evaluated based on potency (concentration at which response occurs) and efficacy (extent of response). A linear growth response was observed in response to prototypical estrogen receptor agonists (17β-estradiol, genistein, bisphenol A, nonylphenol, and 4-tert-octylphenol). Several compounds, including bisphenol A and genistein, induced cell growth comparable in efficacy to that of 17β-estradiol, but with decreased potency. Progestins, androgens, and corticosteroids invoked a biphasic growth response indicative of changes in cell number or cell morphology. Results from this cell growth assay were compared with results from additional estrogen receptor (ER) binding and transactivation assays. Chemicals detected as active in both the cell growth and ER receptor binding assays demonstrated potencies highly correlated with two ER transactivation assays (r = 0.72; r = 0.70). While ER binding assays detected chemicals that were highly potent or efficacious in the T-47D cell growth and transactivation assays, the binding assays lacked sensitivity in detecting weakly active compounds. In conclusion, this cell-based assay rapidly detects chemical effects on T-47D growth and shows potential, in combination with other HTS assays, to detect environmentally relevant chemicals with potential estrogenic activity.
Cholinesterase affects dynamic transduction properties from vagal stimulation to heart rate (1998)

Recent investigations in our laboratory using a Gaussian white noise technique showed that the transfer function representing the dynamic properties of transduction from vagus nerve activity to heart rate had characteristics of a first-order low-pass filter. However, the physiological determinants of those characteristics remain to be elucidated. In this study, we stimulated the vagus nerve according to a Gaussian white noise pattern to estimate the transfer function from vagal stimulation to the heart rate response in anesthetized rabbits and examined how changes in acetylcholine kinetics affected the transfer function. We found that although increases in the mean frequency of vagal stimulation from 5 to 10 Hz did not change the characteristics of the transfer function, administration of neostigmine (30 microg . kg-1 . h-1 iv), a cholinesterase inhibitor, increased the dynamic gain from 8.19 +/- 3.66 to 11.7 +/- 4.88 beats . min-1 . Hz-1 (P < 0.05), decreased the corner frequency from 0.12 +/- 0.05 to 0.04 +/- 0.01 Hz (P < 0.01), and increased the lag time from 0.17 +/- 0.12 to 0.27 +/- 0.08 s (P < 0.05). These results suggest that the rate of acetylcholine degradation at the neuroeffector junction, rather than the amount of available acetylcholine, plays a key role in determining the dynamic properties of transduction from vagus nerve activity to heart rate.
Induction of intracellular Ca2+ mobilization and cytotoxicity by hybrid mouse monoclonal antibodies. Fc gamma RII regulation of Fc gamma RI-triggered functions or signaling? (1991)

We studied the interaction of bispecific mouse mAb with human IgG Fc receptors, and assessed their ability to activate the monocytic cell line U937. Binding of monomeric hybrid anti-HuIgA1/HRP mAb to the high-affinity IgG receptor, Fc gamma RI, on U937 cells was only observed when mAb with one or more mIgG2a H chains (hybrid mIgG1-2a, mIgG2a-2b, and mIgG2a-2a) were used. These Fc gamma RI-bound hybrid mAb were capable of enhancing the internal free cytosolic Ca2+ concentration ([Ca2+]i) in U937 cells only when bound mIgG were cross-linked using F(ab')2 fragments of goat anti-mIg antibody. A hybrid mIgG1-2a mAb were cross-linked using goat anti-mIgG1 antibody, showing that the hybrid mAb themselves mediate the induction of Ca2+ increase. Remarkably, anti-Fc gamma RII mAb IV.3 was able to inhibit the Ca2+ increase induced via mIgG2a-1 or mIgG1-2a hybrid mAb completely, despite the fact that we could not detect any effect of IV.3 on binding of monomeric hybrid mIgG1-2a or mIgG2a-1 mAb to U937. The hybrid mAb were also able to induce lysis of HuIgA1-coated E using U937 effector cells. This lysis was completely inhibited by preincubation of U937 cells with mIgG2a mAb TB-3, which blocks Fc gamma RI via its Fc-part ("Kurlander phenomenon"). In contrast, Fc gamma RII-blocking mAb IV.3 and CIKM5 caused a significant enhancement of the antibody-dependent cellular cytotoxicity (ADCC) activity mediated by hybrid mIgG1-2a and mIgG2a-2b mAb. This enhancement did not occur when the parental anti-HuIgA1/2a or the hybrid anti-HuIgA1/HRP/2a-2a mAb were evaluated for ADCC activity. These findings suggest that hybrid mAb not only can bind to Fc gamma RI, but can mediate functional activation of myeloid cells. Given the effect of mAb IV.3 on [Ca2+]i changes and ADCC triggered through IgG1-2a mAb, we suggest that Fc gamma RII may have a role in the regulation of Fc gamma RI-triggered functions or signaling.
