Multi-Agent Path Integral Control for Interaction-Aware Motion Planning in Urban Canals (2023)

Autonomous vehicles that operate in urban environments shall comply with existing rules and reason about the interactions with other decision-making agents. In this paper, we introduce a decentralized and communication-free interaction-aware motion planner and apply it to Autonomous Surface Vessels (ASVs) in urban canals. We build upon a sampling-based method, namely Model Predictive Path Integral control (MPPI), and employ it to, in each time instance, compute both a collision-free trajectory for the vehicle and a prediction of other agents' trajectories, thus modeling interactions. To improve the method's efficiency in multi-agent scenarios, we introduce a two-stage sample evaluation strategy and define an appropriate cost function to achieve rule compliance. We evaluate this decentralized approach in simulations with multiple vessels in real scenarios extracted from Amsterdam's canals, showing superior performance than a state-of-the-art trajectory optimization framework and robustness when encountering different types of agents.

Residential microwave oven interference on Bluetooth data performance (2004)

With both Bluetooth and microwave ovens operating in the same frequency band, fears have arisen about the effects of microwave oven interference on Bluetooth networks. While Bluetooth devices use frequency hopping spread spectrum (FHSS), the high power output of microwave ovens may still pose a threat to Bluetooth networks. We therefore endeavored to characterize microwave oven behavior and understand its effect upon Bluetooth networks. Our experimental results show that Bluetooth devices will tolerate a high level of interference. With two Bluetooth devices forming a piconet placed within 1 m of an oven, the Bluetooth throughput was significantly greater than half of the maximum throughput rate. Moving to a distance around 10 m from the oven showed very little degradation to the throughput due to interference. The effects of microwave oven interference, while noticeable, are by no means fatal. The results also showed no gain from the forward error correction (FEC) used on some Bluetooth packets.
Exploring Series and Parallel Combinations of Capacitors by Inquiry (2006)

Using lightbulbs and batteries for qualitatively examining resistive combinations has a long and venerable history. There is, however, no similar body of work that explores combinations of capacitors in a similar fashion. This paper begins to fill that gap by describing an inquiry-based method to examine combinations of capacitors.
Thermal conductivity and diffusivity in swine myocardium (2002)

This paper describes an experimental technique for the measurement of thermal conductivity, and thermal diffusivity using self-heated thermistors. Thermal probes are constructed by placing a miniature thermistor at the tip of a plastic catheter. The volume of tissue over which the measurement occurs depends on the surface area of contact between the thermistor and the tissue. Electrical power is delivered to a spherical thermistor positioned invasively within the tissue of interest. The electrical power and resulting temperature rise are measured by microcomputer-based instrument. The instrument is calibrated by operating the system in media of known thermal properties. Thermal property measurements in swine myocardium were measured at 27, 37 and 50/spl deg/C.
Development of an MRI phantom for diffusion‐weighted imaging with independent adjustment of apparent diffusion coefficient values and T2 relaxation times (2013)

The proposed phantom allows for standardized in vitro studies of DWI methods and protocols. The obtained MR image contrasts are similar to a variety of biological tissues, which can contribute to optimization of imaging techniques with respect to specific clinical questions. Due to the simplicity of design and the accessibility of the contained compounds, this phantom may also serve as a tool for standardization and calibration.
Characterization of a Novel Acyl Carrier Protein, RkpF, Encoded by an Operon Involved in Capsular Polysaccharide Biosynthesis in Sinorhizobium meliloti (1998)

Rhizobial capsular polysaccharides (RKPs) play an important role in the development of a nitrogen-fixing symbiosis with the plant host and in Sinorhizobium meliloti AK631 functional rkpABCDEF genes are required for the production of RKPs. After cloning the rkpF gene, we overexpressed and purified the derived protein product (RkpF) in Escherichia coli. Like acyl carrier protein (ACP), the RkpF protein can be labeled in vivo with radioactive beta-alanine added to the growth medium. If homogeneous RkpF protein is incubated with radiolabeled coenzyme A in the presence of purified holo-ACP synthase from E. coli, an in vitro transfer of 4'-phosphopantetheine to the RkpF protein can be observed. The conversion from apo-RkpF protein to holo-RkpF protein seems to go along with a major conformational change of the protein structure, because the holo-RkpF protein runs significantly faster on native polyacrylamide gel electrophoresis than the apo-RkpF protein. Electrospray mass spectrometric analysis reveals a mass of 9,585 for the apo-RkpF protein and a mass of 9,927 for the holo-RkpF protein. Our data show that RkpF is a novel ACP.
Expression of multiple isozymes of granulocyte, monocyte, and macrophage esterases in polycythemic Friend erythroleukemia cells (1983)

We examined the expression of cytochemical markers of myeloid and monocyte-macrophage differentiation in conjunction with ultrastructural studies of different malignant erythroleukemic cells isolated from mice infected with the Friend polycythemic virus complex (FLV-P). The amounts of fluoride-sensitive and resistant nonspecific esterase activity increased with the progression of malignancy. Isoelectric focusing resolved this enzyme activity into 13 isozymes in the most malignant Friend cell type tested. These same isozymes were found in the adherent cell population of normal spleens. Two of these isozymes were shown to have chloroacetate esterase activity characteristic of granulocytes. Despite these myeloid and monocyte characteristics, light and electron microscopy showed no morphological evidence of differentiation in either of these lineages. This study demonstrates that the Friend erythroleukemic cell contains markers of three different hemopoietic cell types. The expression of myeloid, monocytic, and erythroid traits in these erythroleukemic cells can be used to monitor their malignant progression.
High Level Design of a Flexible PCA Hardware Accelerator Using a New Block-Streaming Method (2020)

Principal Component Analysis (PCA) is a technique for dimensionality reduction that is useful in removing redundant information in data for various applications such as Microwave Imaging (MI) and Hyperspectral Imaging (HI). The computational complexity of PCA has made the hardware acceleration of PCA an active research topic in recent years. Although the hardware design flow can be optimized using High Level Synthesis (HLS) tools, efficient high-performance solutions for complex embedded systems still require careful design. In this paper we propose a flexible PCA hardware accelerator in Field-Programmable Gate Arrays (FPGA) that we designed entirely in HLS. In order to make the internal PCA computations more efficient, a new block-streaming method is also introduced. Several HLS optimization strategies are adopted to create an efficient hardware. The flexibility of our design allows us to use it for different FPGA targets, with flexible input data dimensions, and it also lets us easily switch from a more accurate floating-point implementation to a higher speed fixed-point solution. The results show the efficiency of our design compared to state-of-the-art implementations on GPUs, many-core CPUs, and other FPGA approaches in terms of resource usage, execution time and power consumption.

Comparison of egg yolk and serum for the detection of Mycoplasma gallisepticum and M. synoviae antibodies by enzyme-linked immunosorbent assay. (1986)

Egg yolk was evaluated in the enzyme-linked immunosorbent assay (ELISA) as an alternative source of antibodies for detection of Mycoplasma gallisepticum (MG) and M. synoviae (MS) infections in chickens. There was no statistically significant difference (P greater than 0.05) between the ELISA geometric mean titers (GMTs) of saline-diluted egg yolk and chloroform-extracted egg yolk, and both preparations had a high correlation coefficient (0.87 for MG; 0.97 for MS). The saline-diluted and chloroform-extracted yolk had a relative sensitivity of 90% and specificity of 98% in the MG ELISA; in MS ELISA they were 100% and 96%, respectively. Hemagglutination-inhibition (HI) results with chloroform-extracted samples were satisfactory, but those with saline-diluted samples were not. Neither preparation was satisfactory for use in the rapid plate agglutination (RPA) test. A 1-ml sample of yolk was compared with the whole-yolk method. The chloroform-extracted whole yolk yielded a significantly higher (P less than 0.05) GMT in the MG ELISA; however, there was no statistically significant difference (P greater than 0.05) between GMTs yielded by the two procedures in the MS ELISA. The correlation coefficients for the two sampling methods were 0.73 for MG ELISA and 0.63 for MS ELISA. ELISA detected no statistically significant difference (P greater than 0.05) between GMTs of serum and chloroform-extracted yolk from individual birds. Results with the HI test were comparable to those with ELISA on the same samples. The RPA test yielded comparable results on the serum samples. No statistically significant differences (P greater than 0.05) were observed in HI or ELISA antibody levels between egg-yolk samples and sera on random samples collected from nine flocks that were MG- and MS-free or were infected with MG, MS, or both; however, egg-yolk samples tended to have slightly higher titers than sera in both tests. The optimum screening dilution of chloroform-extracted yolk for detecting MG and MS antibodies by ELISA was 1:800.
Albumin-Binding Evans Blue Derivatives for Diagnostic Imaging and Production of Long-Acting Therapeutics (2016)

One of the major design considerations for a drug is its pharmacokinetics: a drug with short blood half-life is less available at a target organ which in turn dictates treatment with either high or more frequent doses, and increases the likelihood of undesirable side effects. One method to improve drug pharmacokinetics is adding functional chemical groups to the drug molecule that can increase the half-life in the blood, hopefully, without significantly affecting its desired biological activity. Evans Blue (EB) dye reversibly binds to serum albumin with moderate affinity and has a long blood half-life. The binding of EB to albumin has been exploited to quantify protein leakage as an indicator of increased vascular permeability. Design of new chemical entities based on EB structure and coupling them to drugs, enables the usage of albumin as a reversible carrier in the blood and improves drug's half-life. This Topical Review summarizes the recent developments of various EB derivatives for molecular imaging and therapy applications.
Anti-HIV Activity of the Combination of Didanosine and Hydroxyurea in HIV-1-Infected Individuals (1995)

HIV is known to be present in massive amounts in both resting and actively replicating cells in infected individuals. We tested the combination of didanosine and hydroxyurea, known to suppress viral production in vitro in both of these cell types, in a small number of asymptomatic patients. After 3 months of well tolerated treatment, we observed a large reduction of viral load in the peripheral blood of all 12 patients, down to nonquantifiable levels in 7 of 12 as measured by infectious virus titer, and 6 of 12 as measured by plasma HIV-RNA. In this subgroup of 6 patients, whose baseline HIV-RNA was below 14,000 copies/ml, the median increase in CD4+ count after 90 days of treatment was 244 cells/mm3.
Growth and Hydrogen Production of Rubrivivax gelatinosus CBS (2011)

Rubrivivax gelatinosus CBS is a purple non-sulfur photosynthetic bacterium that has been found to produce substantial amounts of Hydrogen (H2) which could be used as a clean burning biofuel. CBS has been known to grow on a variety of carbon sources, but it is unknown as to which carbon sources it has the greatest potential to use, and this understanding could be helpful in engineering future strains of the bacteria. Hydrogen production in CBS occurs when carbon monoxide (CO) is present and is presumed to be under the control of the RcoM transcription factor. When CBS wild-type strains were grown in different carbon sources it was found that the bacteria were able to use the organic acid substrates much more successfully than the sugar substrates. This is useful in that organic acids are often waste products and we can use those products as a nutrient to support the growth of CBS. When the rcoM gene was deleted from the CBS bacteria, growth with CO in the mutant strain ceased, and H2 production and protein production were greatly reduced when compared to the wild-type. Understanding how RcoM impacts the CO to H2 pathway will allow us to better engineer the pathway to further increase the production of H2 in CBS.
NDNCERT (2017)

The Named Data Networking (NDN) architecture builds the security primitives into the network layer: all retrieved data packets must be signed to ensure their integrity authenticity and provenance. To ensure that these primitives are used in a meaningful way without imposing undue burdens on NDN users, the management of cryptographic keys and certificates needs to work in a simple, secure, and user-friendly way. This poster introduces the NDN Trust Management system (NDNCERT) which is designed to fill this need. NDNCERT provides flexible mechanisms to delegate trust between certificates, either within a single device (managing permissions for local applications on a node to operate under a given namespace) or across devices/entities. NDNCERT features a modular design for security challenges that establish trust through out-of-band means for certificate issuing. Once a node or an application obtains a valid certificate for its namespace (or being configured with a self-signed certificate), it automatically becomes a certificate authority for its namespace, and can use the same NDNCERT protocol to produce certificates for the sub-namespaces.
Proteomic investigation of the impact of oxygen on the protein profiles of hyaluronic acid‐producing Streptococcus zooepidemicus (2009)

Abstract Hyaluronic acid (HA) is a linear and negatively charged polysaccharide regularly used in medicine and cosmetics. Recently, Streptococcus zooepidemicus has been exploited in the fermentation industry to produce HA. Many studies showed that higher amounts of HA were produced under aerobic condition compared with anaerobic conditions. In order to explore the effect of oxygen on the HA synthesis in S. zooepidemicus , 2‐DE was used to compare the proteomes of aerobically and anaerobically fermented bacteria to identify proteins, which might be associated with the influence of oxygen on the HA synthesis. Totally nine pairs of 2‐DE gels collected from three batches were compared and nine over‐expressed proteins were observed in aerobically fermented bacteria. These proteins were identified by LC‐MS/MS as dihydrolipoamide dehydrogenase, UDP‐acetyl‐glucosamine pyrophosphoylase, dihydrolipoamide‐ S ‐acetyltransferase, and acetoin dehydrogenase α and β chains, respectively. These up‐regulated proteins were involved in acetoin dissimilation, the central carbon metabolism, and the HA anabolic pathway, implicating that oxygen might augment the expression of genes that are involved in central energy metabolism, acetoin reutilization, and HA biosynthesis to enhance the amount of acetyl‐CoA as such more acetyl‐CoA can be divergent from the central carbon metabolism to replenish acetyl‐CoA for the HA synthesis.

Moderate External Rotation of Tibial Component Generates More Natural Kinematics Than Internal Rotation After Total Knee Arthroplasty (2022)

This study aimed to investigate the influence of tibial malrotation on knee kinematics after total knee arthroplasty (TKA). A symmetric fixed-bearing posterior-stabilized prosthesis was implanted in the validated knee model with different rotational alignments of the tibial component (neutral, 3° external rotation, 5° external rotation, 3° internal rotation, and 5° internal rotation). Computational kinematic simulations were used to evaluate the postoperative kinematics of the knee joint including anteroposterior translation femoral condyles and axial rotation of tibial component during 0°-135° knee flexion. The results revealed that the neutral position of the tibial component was not the closest kinematics to the intact knee, the model with 5° external rotation of the tibial component showed the closest lateral condyle translation and tibial axial rotation, and moderate external rotation could improve the kinematics after TKA.
Influences of North Pacific anomalies on Indian summer monsoon onset (2021)

Abstract This study finds a significantly decreasing (increasing) trend (1979–2018) of sea level pressure (SLP) over coastal East Asia (far North Pacific) during May and June, which resembles the negative (positive) Pacific Decadal Oscillation (PDO) (North Pacific Oscillation, NPO)‐like pattern. Thus, we examine May composite differences between early and late Indian summer monsoon (ISM) onset years. Sea surface temperature (SST) differences show that early (late) ISM onset is accompanied by a negative (positive) PDO‐like state. Whereas, in SLP, an intense low pressure over northwestern India, the Arabian Sea to Southeast Asia (far North Pacific, East Asia) is associated with the early (late) onset. During the early onset, warm surface air temperature (SAT) anomalies over southeast Russia propagate towards Central Asia to the Middle East and the northwest Indian subcontinent, strengthening the land‐sea thermal contrast, which subsequently strengthens the monsoon low. We thus show how the positive NPO, negative PDO, and high spring Bering Sea ice link with the SAT anomalies. In the early onset, more wave packets generated in response to these North Pacific anomalies propagate towards the Atlantic and European region, reaching and converging over the northwest Indian subcontinent. The warm surface anomalies possibly draw eastward‐propagating waves towards northwest India, thus intensifying the monsoon low there. Meanwhile, in the CAM5 PDO simulation, we observe a similar pattern of atmospheric responses, where warm SAT anomalies associated with stationary Rossby wave trains propagate from the North Pacific towards the North Atlantic to Central Asia and the northwest Indian subcontinent, strengthening the monsoon low. Terefore, our study highlights the crucial role of the North Pacific anomalies in modulating the ISM onset processes via atmospheric pathways.
Seleção de linhagens de Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) para o controle das traças Tuta absoluta (Meyrick) e Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae) (2001)

Foram estudados aspectos biológicos e o parasitismo de seis linhagens de Trichogramma pretiosum Riley, criadas em ovos das traças Tuta absoluta (Meyrick) e Phthorimaea operculella (Zeller), com o objetivo de selecionar as linhagens com melhores características biológicas e mais agressivas no controle dessas traças. O ciclo de desenvolvimento, a viabilidade, a razão sexual e a porcentagem de parasitismo foram semelhantes entre as seis linhagens estudadas com relação ao parasitismo de ovos de T. absoluta. Em ovos de P. operculella, as linhagens L1, L4 e L6 foram as mais agressivas. Baseando-se na análise de agrupamento (cluster analysis), as linhagens L1, L2, L4 e L5, quando criadas em ovos de T. absoluta, mostraram comportamento semelhante. Para P. operculella, foram observadas semelhanças entre as linhagens L1, L3, L4 e L6. Considerando-se as características biológicas desejáveis, ou seja, maior parasitismo, encurtamento do ciclo, maior viabilidade e predominância de fêmeas, são mais indicadas, para ambas as traças, as linhagens L1 e L4.

Estimation of the Weight of Vegetation Using Microwave Transmission Measurements (1986)

This work reports on a technique for inferring the weight of standing vegetation from microwave transmission measurements. This nondestructive technique is invaluable when it is necessary to remeasure vegetation plots to examine effects with time. Such applications include ecological studies of the forest understory. Results are reported for field tests with pine trees in Virginia and stands of softwood, hardwood, and mixed-wood in Maine. It was found that depolarization-compensated attenuation at 12 GHz is highly correlated with the weight of vegetation and woody shoots less than 1.27 cm (one-half inch) in diameter along the signal path. The method was applied to ecological studies into ways of reducing spruce budworm defoliation.
Analysis of a strip-grating twist reflector (1990)

We present a rigorous analysis of scattering from a twist reflector composed of a strip grating placed on a dielectric slab and backed by a conducting metallic sheet. The obliquely incident, arbitrarily polarized plane wave is decomposed into fast- and slow-polarized modes, and a complete and accurate solution of the total diffracted fields is derived. The solution procedure used is an extension of our solution procedure developed for the analysis of scattering from a strip grating. We calculate the optimum height w, in order for the fast- and slow-polarized diffracted fields to be in phase, for various angles of incidence and different periods of the strip grating. With air as the dielectric between the strip grating and the ground plane, it is shown that a strip-grating twist polarizer behaves similarly to the corrugated-surface twist polarizer.
