Ultra-compact and highly sensitive pressure sensor based on nano-gauge detection and cointegrated with inertial sensors (2016)

This paper reports for the first time the experimental pressure response of an ultra-compact and highly linear absolute pressure sensor based on suspended piezoresistive nano-gauges with mechanical amplification and embedded low voltage self-test. Nano-gauges being suspended and structurally protected from the external environment, it can be used in high temperature and harsh environments. Unidirectional and amplified stress on the nano-gauges allows drastic miniaturization (0.12mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> footprint for a 1 bar structure). In addition, the M&NEMS technology used for the manufacturing enables its direct cointegration with inertial sensors.
Strength Retention in Hot‐Pressed Si 3 N 4 Ceramics with Lu 2 O 3 Additives after Oxidation Exposure in Air at 1500°C (2002)

The effect of oxidation exposure on room‐temperature flexural strength was examined in 3.33‐ and 12.51‐wt%‐Lu 2 O 3 ‐containing hot‐pressed Si 3 N 4 ceramics exposed to air at 1500°C for up to 1000 h. After oxidation exposure, the room‐temperature strength of the ceramics was degraded, and strength retention decreased with time at temperature, dependent on the amount of additive. The retention in room‐temperature strength displayed by the two compositions after 1000 h of oxidation exposure was 75%–80%. The degradation in strength was attributed to the formation of new defects at and/or near the interface between the oxide layer and the Si 3 N 4 bulk during oxidation exposure.
Antibody Response to Simian Virus 40 Tumor Antigen in Nude Mice Reconstituted with T Cells (1977)

Athymic BALB/c nude mice (nu/nu) fail to generate circulating antibodies to simian virus 40 (SV40) tumor (T) antigen when immunized with SV40-transformed mouse cells or with T antigen positive somatic cell hybrids derived from SV40-transformed human and normal mouse parental cells. However, normal BALB/c mice readily produce antibodies to SV40 T antigen. When nude mice were reconstituted with normal syngeneic T lymphocytes from spleen or thymus source, the humoral immune responsiveness to SV40 T antigen was restored.
Infestation by cabbage aphid (Brevicoryne brassicae) on oilseed rape (Brassica napus) causes a long lasting induction of the myrosinase system (2003)

Abstract Cabbage aphid, Brevicoryne brassicae (L.) (Hemiptera: Aphididae), is specialised on cruciferous plants and constitutes a world‐wide problem with a substantial negative impact on agriculture and horticulture. The myrosinase‐glucosinolate system present in crucifers is believed to serve as an important barrier to general herbivores, whereas specialist insects rely on this system for host recognition. Two proteins with unknown function, myrosinase binding protein (MBP) and myrosinase associated protein (MyAP), are also present in such plants and bind to specific myrosinases. In order to study regulation and overall effects on the myrosinase system, one leaf of oilseed rape ( Brassica napus L.) (Brassicaceae) plants at the two‐leaf stage was exposed to cabbage aphids for 1 h. After removal of the insects, infested and non‐infested leaves were analysed by Northern blot analysis for the presence of MBP, MyAP, and myrosinase transcripts at different time points up to 48 h. MBP transcript levels continued to rise during the whole experiment, and were seven‐ to eight‐fold higher compared with control plants 48 h after removal of the aphids. At 24 h the MyAP transcripts reached maximal levels and were four‐fold higher than the control levels. Myrosinase transcripts were down regulated by aphid infestation and the level was less than half that of the control plants at 48 h. Apparently cabbage aphid infestation causes both transient and more long lasting (up to 48 h) effects on the myrosinase system of the host.
QoS restoration for dependable networks (2002)

QoS restoration, the capability of a network to help maintain the QoS above pre-defined minimum requirements in case of failures or load fluctuations, is proposed. If failures or load fluctuations occur, a network with QoS restoration reallocates surplus network resources from working connections as well as from pre-assigned spare capacity by using a distributed algorithm to restore the degraded connections. This distributed algorithm is composed of the flooding of failure or load fluctuation notification, working connection reconfiguration signaling, and a conventional self-healing or distributed algorithm against load fluctuations. Theoretical maximum restoration ratios for various failures were calculated by integer programming. These analytical evaluations show that resource reallocation allows high ratio of restoration from single-link failures having no spare resources, and double-link failures having spare resources prepared for single-link failures. Simulation results show that the proposed distributed algorithm achieves a restoration ratio close to the theoretical maximum regardless of whether pre-assigned spare capacity exists.

Fabry-Perot displacement interferometry in air (2013)

We demonstrate Fabry-Perot interferometry for displacement metrology in air using light at both 1560 nm and 1064 nm. Lasers are locked to the cavity and their frequencies are measured with an optical frequency comb.
DNA Methylation Is Globally Disrupted and Associated with Expression Changes in Chronic Obstructive Pulmonary Disease Small Airways (2013)

DNA methylation is an epigenetic modification that is highly disrupted in response to cigarette smoke and involved in a wide spectrum of malignant and nonmalignant diseases, but surprisingly not previously assessed in small airways of patients with chronic obstructive pulmonary disease (COPD). Small airways are the primary sites of airflow obstruction in COPD. We sought to determine whether DNA methylation patterns are disrupted in small airway epithelia of patients with COPD, and evaluate whether changes in gene expression are associated with these disruptions. Genome-wide methylation and gene expression analysis were performed on small airway epithelial DNA and RNA obtained from the same patient during bronchoscopy, using Illumina's Infinium HM27 and Affymetrix's Genechip Human Gene 1.0 ST arrays. To control for known effects of cigarette smoking on DNA methylation, methylation and gene expression profiles were compared between former smokers with and without COPD matched for age, pack-years, and years of smoking cessation. Our results indicate that aberrant DNA methylation is (1) a genome-wide phenomenon in small airways of patients with COPD, and (2) associated with altered expression of genes and pathways important to COPD, such as the NF-E2-related factor 2 oxidative response pathway. DNA methylation is likely an important mechanism contributing to modulation of genes important to COPD pathology. Because these methylation events may underlie disease-specific gene expression changes, their characterization is a critical first step toward the development of epigenetic markers and an opportunity for developing novel epigenetic therapeutic interventions for COPD.
Ophthalmic Manifestations and Long-Term Visual Outcomes in Patients with Cobalamin C Deficiency (2016)

This longitudinal study reports ocular outcomes in the largest group of patients with cblC deficiency systematically examined at a single center over an extended period. Differences in progression and severity of macular degeneration, optic nerve pallor, and vascular attenuation between homozygous c.271dupA (p.R91KfsX14) patients and compound heterozygotes were noted. The pace and chronicity of ophthalmic manifestations lacked strict correlation to metabolic status as measured during visits. Prenatal or early treatment, or both, may have mitigated ocular disease, leading to better functional acuity, but patients still progressed to severe macular degeneration. The effects of prenatal or early treatment, or both, in siblings; the manifestation of severe disease in infancy; the presence of comorbid developmental abnormalities; and the possible laminar structural defect noted in many patients are findings showing that cblC deficiency displays a developmental as well as a degenerative ocular phenotype.
A Pharmacophore Model Specific to Active Site of CYP1A2 with a Novel Molecular Modeling Explorer and CoMFA (2012)

Comparative molecular field analysis (CoMFA) is a widely used 3D-QSAR method by which we can investigate the potential relation between biological activity of compounds and their structural features. In this study, a new application of this approach is presented by combining the molecular modeling with a new developed pharmacophore model specific to CYP1A2 active site. During constructing the model, we used the molecular dynamics simulation and molecular docking method to select the sensible binding conformations for 17 CYP1A2 substrates based on the experimental data. Subsequently, the results obtained via the alignment of binding conformations of substrates were projected onto the active- site residues, upon which a simple blueprint of active site was produced. It was validated by the experimental and computational results that the model did exhibit the high degree of rationality and provide useful insights into the substrate binding. It is anticipated that our approach can be extended to investigate the protein-ligand interactions for many other enzyme-catalyzed systems as well.
Tiny Bubbles; Composite Cocktails for Medical Applications (2016)

Tiny bubbles or glass microspheres/microcapsules are used in our society today in many ways. The microspheres can be solid or hollow and represent particles that are generally in the range of 0.1–100 μm. Solid and hollow microspheres have significantly different densities, properties, and capabilities and are commercially available. Special morphologies, formulations, and compositions can also be achieved by a variety of techniques in the laboratory. One of the most interesting morphologies of these tiny bubbles, are porous wall hollow glass microspheres, which are glass micro‐balloons in which through‐wall porosity was induced in the thin outer shells and controlled, on a scale of 10–100 nm. This unique porosity can be used to fill the microspheres with a variety of cargos of various contents that can later be released on demand. For medical applications, an interdisciplinary team investigated these tiny bubbles, as part of a new series of composites or medical cocktails. The microspheres are key components in the composites and can be used alone or mixed in various amounts and ratios, with a variety of contents, outer coatings, and/or biocompatible matrices, resulting in a wide range of medical cocktails designed and tailored for various applications.
Final Results of a Phase I/II Multicenter Trial of WST11 Vascular Targeted Photodynamic Therapy for Hemi-Ablation of the Prostate in Men with Unilateral Low Risk Prostate Cancer Performed in the United States (2016)

Hemi-ablation of the prostate with WST11 vascular targeted photodynamic therapy was well tolerated and resulted in a negative biopsy in the treated lobe in the majority of men. Dosing parameters and the light dose index appear related to tissue response as determined by magnetic resonance imaging and biopsy. These parameters may serve as the basis for further prospective studies.
Reliable operation of lattice-mismatched indium gallium arsenide photodetectors grown on silicon substrates (2002)

In/sub 0.53/Ga/sub 0.47/As-InP photodetectors for the 0.9-1.7 mu m spectrum have been fabricated with compositional step-grading (using hydride vapor phase epitaxy) upon both GaAs-Si substrates (deposited by metallorganic chemical vapor deposition) and bulk GaAs substrates. Both exhibited good device performance with dark currents (at -5 V) near 100 nA for the GaAs-Si substrate and near 1 nA for the bulk GaAs substrate. Measured dark currents decreased an order of magnitude sequentially as the applied stress was reduced from wafer form to chip form. Dark currents decreased further after 1500 h of aging at 125 degrees C.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Twelve polymorphic microsatellite loci from the Asian citrus psyllid, Diaphorina citri Kuwayama, the vector for citrus greening disease, huanglongbing (2007)

Abstract Twelve polymorphic microsatellite markers were developed from microsatellite‐enriched DNA libraries and mined from an expressed sequence tags library of Diaphorina citri , the vector of the citrus greening disease (huanglongbing). Analysis of 288 individuals from Florida, Texas, and Brazil showed that allelic diversity ranged from three to eight alleles per locus and observed and expected heterozygosities ranged from 0.014 to 0.569 and from 0.052 to 0.653, respectively. These variable microsatellite loci can provide means for assessing overall genetic variation and migration patterns for this agriculturally important pest species. This information can be used to aid in developing successful management strategies.

Merging parallel-plate and levitation actuators to enable linearity and tunability in electrostatic MEMS (2019)

In this study, a linear electrostatic MEMS actuator is introduced. The system consists of a MEMS cantilever beam with combined parallel-plate and electrostatic levitation forces. By using these two forcing methods simultaneously, the static response and natural frequency can be made to vary linearly with the voltage. The static response shows a linear increase of 90 nm/V and is maintained for more than 12μm of the tip displacement. The natural frequency shows a linear increase of 16 Hz/V and is maintained throughout a 2.9 kHz shift in the natural frequency. This wide range of linear displacement and frequency tunability is extremely useful for MEMS sensors and actuators, which suffer from the inherent nonlinearity of electrostatic forces. A theoretical model of the system is derived and validated with experimental data. Static response, natural frequency, and frequency response calculations are performed. Merging these two mechanisms enables high oscillation branches for a wide range of frequencies with potential applications in MEMS filters, oscillators, and sensors.
Manipulation and Orientation of Zeolite L by Using a Magnetic Field (2014)

Abstract A simple approach for the functionalization of cylindrically shaped zeolite L crystals with iron oxide magnetic nanoparticles is reported. These functionalized zeolites can be aligned very easily by applying a magnetic field in solution, on different substrates, and in a polymeric matrix. The aligned zeolite loaded with fluorescent dyes are anisotropic in both absorption and fluorescence owing to the linear arrangement of the channels and the restricted rotation of the molecules inside the channels. These findings can be applied on polymeric matrices, such as poly[3‐3′(vinylcarbazole)].
Conformational Transitions in the Cell Binding Domain of Fibronectin (1995)

Plasma fibronectin readily changes shape in response to environmental conditions which may, in turn, lead to differential expression of its multiple functional sites. To test this possibility, the expression of two of the type III modules within cell binding domain of fibronectin was assessed with monoclonal antibodies (mAb). Utilizing proteolytic and recombinant fragments of plasma fibronectin, the epitopes recognized by mAbIII-9 and mAbIII-10 were localized to the ninth and tenth (RGD-containing) type III repeats of fibronectin, respectively. Both mAb inhibited the adhesion of platelets to immobilized fibronectin, suggesting that the recognized epitopes resided in close spatial proximity to the cell binding sites. Radioimmunoassay and Scatchard analyses showed that, in solution, each dimeric fibronectin molecule bound two mAbIII-9 but only one mAbIII-10 molecule (ionic strength 0.15, pH 7.4). The binding of a single mAbIII-10 per fibronectin molecule was verified by electron microscopy. Heparin, heparan sulfate, gangliosides (but not chondroitin sulfates A and B and hyaluronic acid), and self-association increased the apparent affinity of mAbIII-10 for soluble fibronectin. Adsorption of fibronectin onto a polystyrene surface resulted in the appearance of an additional binding site for mAbIII-10. MAbIII-9 binding also was altered by fibronectin immobilization. These results suggest that the deposition of fibronectin and its interaction with components of the extracellular matrix can modulate the expression of the cell binding domains including the RGDS-containing type III repeat. Exposure of the second tenth type III repeat within the fibronectin dimer, as a result of unfolding on a surface, could contribute to the enhanced adhesiveness of adsorbed fibronectin.

Obstacle detection for self-driving cars using only monocular cameras and wheel odometry (2015)

Mapping the environment is crucial to enable path planning and obstacle avoidance for self-driving vehicles and other robots. In this paper, we concentrate on ground-based vehicles and present an approach which extracts static obstacles from depth maps computed out of multiple consecutive images. In contrast to existing approaches, our system does not require accurate visual inertial odometry estimation but solely relies on the readily available wheel odometry. To handle the resulting higher pose uncertainty, our system fuses obstacle detections over time and between cameras to estimate the free and occupied space around the vehicle. Using monocular fisheye cameras, we are able to cover a wider field of view and detect obstacles closer to the car, which are often not within the standard field of view of a classical binocular stereo camera setup. Our quantitative analysis shows that our system is accurate enough for navigation purposes of self-driving cars and runs in real-time.

Linearization Technologies for High Efficiency Power Amplifier of Cellular Base Stations (2021)

This paper presents linearization technologies for high efficiency power amplifiers of cellular base stations. These technologies are important to actualizing highly efficient power amplifiers that reduce power consumption of the base station equipment and to achieving a sufficient non-linear distortion compensation level. It is well known that it is very difficult for a power amplifier using linearization technologies to achieve simultaneously high efficiency and a sufficient non-linear distortion compensation level. This paper presents two approaches toward addressing this technical issue. The first approach is a feed-forward power amplifier using the Doherty amplifier as the main amplifier. The second approach is a digital predistortion linearizer that compensates for frequency dependent intermodulation distortion components. Experimental results validate these approaches as effective for providing power amplification for base stations.
