SF-ESPRIT: An Efficient 3D Localization for MIMO SFCW Radars using Space-Frequency Array (2023)

In this paper, the problem of 3D localization of multiple point targets with Multiple Input Multiple Output (MIMO) Stepped Frequency Continuous Wave (SFCW) radar is considered. We propose to combine the channel response of the virtual Uniform Rectangular Array (vURA) obtained by scanning at uniformly spaced frequency points to form a larger array referred as Space-Frequency (SF) array. Towards estimating jointly the azimuth, elevation and range of multiple targets with this SF-array, we propose a new ESPRIT based algorithm which we refer to as SF-ESPRIT. The localization capability of SF-ESPRIT largely depends upon the number of frequency scanning points, and further possess the ability to localize far more targets than the dimension of the vURA. In addition, the inter-element spacing requirement of vURA is also greatly relaxed. We show that with this proposed approach one can obtain much better localization performance with fewer elements than the standard existing methods. Appropriate numerical results are presented to corroborate these findings.
Hydrogenation of Imino‐bisnitriles—Synthesis of Novel Triamines (2007)

Abstract The hydrogenation of iminonitriles and iminobisnitriles of type 1a–f is a particularly difficult process as the intermediate dieneamines are highly susceptible to addition reactions. A short general method of preparation and purification of 2‐aminomethylene‐1,3‐diamine of type 2a–e by catalytic hydrogenation of iminobisnitriles is described. Keywords: hydrogenationimino‐bisnitriletriamine
Eikenella corrodens adherence to human buccal epithelial cells (1981)

The mechanism of Eikenella corrodens adherence to human buccal epithelial cells in vitro was studied. Initial experiments to determine the optimal conditions for adherence of E. corrodens to buccal epithelial cells showed that adherence was dependent on time, temperature, bacterial concentration, and pH. Different strains of E. corrodens varied in their ability to adhere, and strain 1073 showed the greatest ability in adherence. Strain 1073 was selected for studies of adherence mechanisms. Trypsin treatment or heating (100 degrees C, 10 min) of the bacterial cells abolished their capacity to adhere to buccal epithelial cells. Treatment of buccal epithelial cells with trypsin also abolished adherence of E. corrodens 1073, whereas neuraminidase treatment of buccal epithelial cells enhanced the adherence. The adherence was inhibited by ethylenediaminetetraacetic acid and restored by adding Ca2+. The adherence was remarkably inhibited by sugars containing D-galactose and n-acetyl-D-galactosamine. Treatment of neuraminidase-treated epithelial cells with sodium metaperiodate or alpha- and beta-galactosidase did not decrease the adherence. These data suggest that adherence of E. corrodens 1073 to human buccal epithelial cells may require the interaction of lectin-like proteins on the bacterial surface with galactose-like receptors on the surface of epithelial cells.

Impact of molecular subtypes on the prediction of distant recurrence in estrogen receptor (ER) positive, human epidermal growth factor receptor 2 (HER2) negative breast cancer upon five years of endocrine therapy (2019)

St Gallen Luminal A-like tumors identified by RT-qPCR display markedly low rates of distant recurrence at ten years follow-up. Patients with such tumors could be spared chemotherapy due to the obviously unfavourable benefit/toxicity ratio.
Co-incidental Von Willebrands disease and immune thrombocytopenia in pregnancy: treatment with high dose intravenous immunoglobulin (1986)

Summary We report a rare association of Von Willebrands disease and idiopathic immune thrombocytopenia in pregnancy. The major threat to the successful outcome of the pregnancy was posed by the acquired disorder. The use of high dose immunoglobulin allowed a normal delivery, without any adverse effects on mother or child.
Two Birds with One Stone: Spontaneous Size Separation and Growth Inhibition of Femtosecond Laser-Generated Surfactant-Free Metallic Nanoparticles via ex Situ SU-8 Functionalization (2018)

Laser ablation in liquids (LAL) offers a facile technique to develop a large variety of surfactant-free nanomaterials with high purity. However, due to the difficulty in the control of the particle synthesis process, the as-prepared nanomaterials always have a broad size distribution with a large polydispersity (σ). Surfactant-free properties can also cause problems with particle growth, which further increases the difficulty in size control of the colloids. Therefore, searching for strategies to simultaneously unify the sizes of colloids and inhibit particle growth has become significantly important for LAL-synthesized nanomaterials to be extensively used for biological, catalytic, and optical applications, in which fields particle size plays an important role. In this work, we present a facile way to simultaneously realize these two goals by ex situ SU-8 photoresist functionalization. Ag nanoparticles (NPs) synthesized by femtosecond laser ablation of silver in acetone at laser powers of 300 and 600 mW were used as starting materials. The synthesized Ag NPs have a broad size distribution between 1 and 200 nm with an average size of ca. 5.9 nm and σ of 127-207%. After ex situ SU-8 functionalization and 6 months storage, most particles larger than 10 nm become aggregates and precipitate, which makes the size distribution narrow with an average diameter of 4-5 nm and σ of 48-78%. The precipitation process is accompanied by the decrease in colloid mass from the initial ∼0.2 to 0.10-0.11 mg after ex situ SU-8 functionalization and 6 months colloid storage. Morphology analysis indicates that ex situ SU-8 functionalization inhibits the particle growth into polygonal nanocrystals. Radical polymerization of SU-8 on Ag NPs is considered to be the reason for both spontaneous size separation and growth inhibition phenomena. Benefiting from Ag NPs embedment and acetone dissolution, the glass-transition temperature of SU-8 photoresist increased from 314 to 331 °C according to thermogravimetric analysis. The universality of ex situ SU-8 functionalization-induced growth inhibition and size separation behaviors is further proved using the Au colloids generated by LAL in acetone. This work is expected to provide a new route for better size control of LAL-synthesized colloids via ex situ photoresist functionalization, although a half of colloidal mass is wasted due to radical polymerization-induced colloidal precipitation.

Chiral cyclopentadienylruthenium sulfoxide catalysts for asymmetric redox bicycloisomerization (2016)

A full account of our efforts toward an asymmetric redox bicycloisomerization reaction is presented in this article. Cyclopentadienylruthenium (CpRu) complexes containing tethered chiral sulfoxides were synthesized via an oxidative [3 + 2] cycloaddition reaction between an alkyne and an allylruthenium complex. Sulfoxide complex 1 containing a p-anisole moiety on its sulfoxide proved to be the most efficient and selective catalyst for the asymmetric redox bicycloisomerization of 1,6- and 1,7-enynes. This complex was used to synthesize a broad array of [3.1.0] and [4.1.0] bicycles. Sulfonamide- and phosphoramidate-containing products could be deprotected under reducing conditions. Catalysis performed with enantiomerically enriched propargyl alcohols revealed a matched/mismatched effect that was strongly dependent on the nature of the solvent.
Potentiation of morphine antinociception by monoamine reuptake inhibitors in the rat spinal cord (1985)

Potentiation of the antinociceptive effects of morphine by the tricyclic antidepressants was assayed in awake restrained rats using the tail-flick test. Intrathecally administered amitriptyline, desipramine or sertraline at doses that had no effect themselves (25-30 micrograms) potentiated a subthreshold parenteral dose of morphine (0.5 mg/kg). The morphine potentiating effect of amitriptyline was prevented by prior administration of parachlorophenylalanine (PCPA). This effect of PCPA was not restored by 5-hydroxytryptophan (5-HTP) but was restored when the animals were left for 14 days to replete. The morphine potentiating effects of amitriptyline, desipramine and sertraline were blocked by intrathecal administration of low doses of the serotonin antagonist methysergide and the alpha-adrenergic antagonists yohimbine and phentolamine but not by the beta-adrenergic antagonist propranolol. The results are consistent with the hypothesis that the potentiation of morphine's antinociceptive effect by tricyclic antidepressants depends on activation of both spinopetal serotonin and adrenergic neurons.

Infectious Bronchitis (2019)

Agent, Infection, and Disease. Infectious bronchitis is caused by the avian coronavirus, infectious bronchitis virus (IBV), which is found worldwide. Infections, depending on the strain, may cause an acute upper-respiratory tract disease, drops in egg production, decreased egg quality, and nephritis. The virus is transmitted by inhalation or direct contact with contaminated objects and morbidity is usually 100%; whereas, mortality can vary depending on a variety of host factors and the strain of the infecting virus. Chickens are the primary host but the virus has also been found in pheasants and peafowl. There exist many different antigenic types of the virus and due to a high rate of mutation, new antigenic variants constantly emerge. As a general rule, different antigenic types and variants have little to no cross-protection.
Comprehensive quantitative analysis of central carbon and amino‐acid metabolism in <i>Saccharomyces cerevisiae</i> under multiple conditions by targeted proteomics (2011)

Decades of biochemical research have identified most of the enzymes that catalyze metabolic reactions in the yeast Saccharomyces cerevisiae. The adaptation of metabolism to changing nutritional conditions, in contrast, is much less well understood. As an important stepping stone toward such understanding, we exploit the power of proteomics assays based on selected reaction monitoring (SRM) mass spectrometry to quantify abundance changes of the 228 proteins that constitute the central carbon and amino-acid metabolic network in the yeast Saccharomyces cerevisiae, at five different metabolic steady states. Overall, 90% of the targeted proteins, including families of isoenzymes, were consistently detected and quantified in each sample, generating a proteomic data set that represents a nutritionally perturbed biological system at high reproducibility. The data set is near comprehensive because we detect 95-99% of all proteins that are required under a given condition. Interpreted through flux balance modeling, the data indicate that S. cerevisiae retains proteins not necessarily used in a particular environment. Further, the data suggest differential functionality for several metabolic isoenzymes.
Probing atomic-scale symmetry breaking by rotationally invariant machine learning of multidimensional electron scattering (2021)

Abstract The 4D scanning transmission electron microscopy (STEM) method maps the structure and functionality of solids on the atomic scale, yielding information-rich data sets describing the interatomic electric and magnetic fields, structural and electronic order parameters, and other symmetry breaking distortions. A critical bottleneck is the dearth of analytical tools that can reduce complex 4D-STEM data to physically relevant descriptors. We propose an approach for the systematic exploration of 4D-STEM data using rotationally invariant variational autoencoders (rrVAE), which disentangle the general rotation of the object from other latent representations. The implementation of purely rotational rrVAE is discussed as are applications to simulated data for graphene and zincblende structures. The rrVAE analysis of experimental 4D-STEM data of defects in graphene is illustrated and compared to the classical center-of-mass analysis. This approach is universal for probing symmetry-breaking phenomena in complex systems and can be implemented for a broad range of diffraction methods.

High-power microwave filters and frequency selective surfaces utilizing EM wave tunneling through &amp;#x2208;-negative layers (2012)

In this paper, we examine electromagnetic wave tunneling through multi-layer structures composed of ϵ-negative (ENG) materials sandwiched by double-positive (DPS) layers. We present an analytical method for synthesizing such structures and demonstrate that these structures can be used to develop frequency selective surfaces (FSS) and filters capable of handling extremely high power levels. An FSS prototype based on this concept is designed and experimentally characterized in a waveguide environment.

Effect of electric fields and fluctuations on confinement in a bumpy torus (1987)

In order to understand the relationships between confinement and space potential (electric field) and between confinement and density fluctuations, plasma parameters in the ELMO Bumpy Torus Scale (EBT-S)[in Plasma Physics and Controlled Nuclear Fusion Research (IAEA, Tokyo, 1974), Vol. 2, p. 141; Plasma Phys. 25, 597 (1983)] have been measured systematically for a wide range of operating conditions. Present EBT plasma parameters do not show a strong dependence on the potential profile, but rather exhibit a correlation with the fluctuations. The plasma pressure profile is found to be consistent with the profile anticipated on the basis of the flute stability criterion for a marginally stable plasma. For a heating power of 100 kW, the stored energy density is found to be restricted to the range between 4.5×1013 eV-cm−3 and 7×1013 eV-cm−3. The lower limit remains constant regardless of heating power and pertains to plasmas lacking an equilibrium and/or stability. The upper limit increases with heating power and is found to result from the onset of instabilities. In between the two limits is a plasma that is in an equilibrium state and is marginally stable. Operational trajectories exist that take the EBT plasma from one limit to the other.
Numerical Simulation of the Abrasive WaterJet (AWJ) Machining: Multi-Fluid Solver Validation and Material Removal Model Presentation (2015)

ABSTRACT: The increasing use of high-pressure water jets in the industry for machining materials yields numerous studies aiming at the optimization of this technology. Since the experimental study of pure or abra-sive water jet cutting is complex to carry out, the numerical simulation of this process stands as an attractive alternative. Such a simulation relies on the coupling of numerical tools devoted on one hand to the description of the high-velocity jet and on the other hand to the deformation of the impacted material. The present paper provides a careful validation for the simulation of an impinging abrasive liquid jet, taking progressively into account the necessary features: impingement, free-surface, particles.
Design and Implementation of Real-Time Multi-sensor Vision Systems (2016)

Implementation of high performance multi-camera / multi-sensor imaging systems that are required to produce real-time video output pose a large number of unique challenges to conventional digital design based on general-purpose processors or GPUs. In potential application areas ranging from machine vision, automotive, and virtual reality, the need for real-time operation with very limited latency dictates customized architectures that are not readily implementable using conventional approaches. In this talk, we will discuss the algorithms that are utilized in such multi-sensor platforms, the specialized architectures that allow streaming video processing, and system-level integration issues. Problems such as light-field reconstruction, multi-band blending, pixel-level interpolation, and rectification are presented, with detailed circuit and system level examples.
A novel invariant-based design approach to carbon fiber reinforced laminates (2016)

An invariant-based design procedure using trace-normalized plane stress stiffness matrix and unit circle failure criterion for carbon fiber reinforced polymer (CFRP) is presented and compared to the traditional design approach. Using the invariant-based design approach, the optimal stiffness-based layup solution is material independent and thus valid for any CFRP. Then, trace of the plane stress stiffness matrix is the only material property needed for strain scaling. Moreover, the unit circle failure criterion is invariant with respect to ply orientation and requires only the unidirectional longitudinal tensile and compressive strains-to-failure, which greatly simplifies testing. In this study, smooth and open-hole plates are evaluated using the traditional design approach and invariant-based design procedures. The results show that the invariant-based design approach greatly simplifies the design procedure of CFRP structural components.
Transplantation of tissue‐engineered cell sheets for stricture prevention after endoscopic submucosal dissection of the oesophagus (2016)

SpliceRadar: A Learned Method For Blind Image Forensics (2019)

Detection and localization of image manipulations like splices are gaining in importance with the easy accessibility of image editing softwares. While detection generates a verdict for an image it provides no insight into the manipulation. Localization helps explain a positive detection by identifying the pixels of the image which have been tampered. We propose a deep learning based method for splice localization without prior knowledge of a test image's camera-model. It comprises a novel approach for learning rich filters and for suppressing image-edges. Additionally, we train our model on a surrogate task of camera model identification, which allows us to leverage large and widely available, unmanipulated, camera-tagged image databases. During inference, we assume that the spliced and host regions come from different camera-models and we segment these regions using a Gaussian-mixture model. Experiments on three test databases demonstrate results on par with and above the state-of-the-art and a good generalization ability to unknown datasets.
Strigolactones are involved in sugar signaling to modulate early seedling development in &lt;i&gt;Arabidopsis&lt;/i&gt; (2016)

Strigolactones are a novel class of plant hormones that interact with multiple signaling molecules, including auxin, abscisic acid, ethylene, and brassinosteroid, to regulate plant growth and development. Recently, researchers have shown that sugars are involved in bud outgrowth control, suggesting a potential interaction between sugars and strigolactone signaling. To better understand the relationship between strigolactones and sugar in plant development, the sugar sensitivity of strigolactone biosynthesis and signaling mutants (max1 and max2) was evaluated in early seedling development with a low-glucose assay. Both max1 and max2 displayed obvious hyposensitivity to glucose repression, as do gin mutants, but they were hypersensitive like the wild type to the high-glucose conditions used for gin mutant screening. The strigolactones acted synergistically with glucose in repressing seedling establishment. A further comparative transcriptomic analysis indicated that the expression of stress-related genes in the max2 mutant is impaired by glucose, and a carbohydrate analysis revealed a reduced hexose content in the max mutants. Our results suggest that the roles of strigolactones in the regulation of early seedling development are probably independent of the HXK1 signaling pathway. Taken together, these findings provide evidence that strigolactones are involved in sugar signaling, thus modulating early seedling development.
