Coordinated control for capturing a highly maneuverable evader using forward reachable sets (2006)

This paper proposes a control strategy based on forward reachable sets (FRSs) analysis for multiple pursuers to capture an evader with a higher maneuverability than the pursuers. The strategy first finds the pursuers' capture states at which their FRSs cover the evader's entire FRS so as to improve the possibility of capture. The pursuers approach these capture states from their initial states in feed-forward control at a low sampling rate. Upon reaching the capture states, the pursuers approach and capture the evader in a feedback manner. The proposed strategy was applied to two pursuit-evasion scenarios and compared to the generic motion tracking algorithm. Results show the efficacy of the proposed strategy and its superiority to the motion tracking algorithm
Energy-Efficient Joint Power Control and Receiver Design for Uplink mmWave-NOMA (2020)

In this paper, we study the energy efficiency (EE) maximization problem of a millimeter-wave system with non-orthogonal multiple access. We consider a base station equipped with a single radio frequency chain, which serves two uplink users through analog beamforming. The EE maximization problem is formulated under minimal rate requirements, involves a joint design of power and receive beamformer, and is non-convex in nature. To tackle it, we decompose the original problem into two sub-problems: the power control and beam gain allocation sub-problem, and the beamforming sub-problem. The former is solved via alternating optimization, while the latter is tackled by transforming it into a convex optimization problem. Simulation results show the effectiveness of the proposed algorithms and its superiority over orthogonal multiple access.
Fourier analysis and Gabor filtering for texture analysis and local reconstruction of general shapes (2009)

Since the pioneering work of Gibson in 1950, Shape-From-Texture has been considered by researchers as a hard problem, mainly due to restrictive assumptions which often limit its applicability. We assume a very general stochastic homogeneity and perspective camera model, for both deterministic and stochastic textures. A multi-scale distortion is efficiently estimated with a previously presented method based on Fourier analysis and Gabor filters. The novel 3D reconstruction method that we propose applies to general shapes, and includes non-developable and extensive surfaces. Our algorithm is accurate, robust and compares favorably to the present state of the art of Shape-From-Texture. Results show its application to non-invasively study shape changes with laid-on textures, while rendering and re-texturing of cloth is suggested for future work.
Explicit construction of finite-dimensional nonlinear filters with state space dimension 3 (2002)

In this note, we use the Wei-Norman approach (1964) to explicitly construct finite-dimensional nonlinear filters with state space dimension three. It is shown that from the Lie algebraic point of view, generically all finite-dimensional recursive filters are of this form.
Tamm State-Coupled Emission: Effect of Probe Location and Emission Wavelength (2014)

We report the effect of the probe location and wavelength on the emission spatial distribution and spectral properties of fluorophores located on structures which display Tamm states. Our structure consists of a one-dimensional photonic crystal (1DPC)-that is, a multilayer structure of alternate high and low refractive index dielectrics-and a thin top silver film. Simulations show the presence of Tamm and surface plasmon modes in the structure. The electric field intensities for the Tamm modes are located mostly in the dielectric layer below the metal film. The corresponding field intensities for the surface plamon modes are located above the metal film in the distal side. Tamm states can be in resonance with the incident light normal or near normal to the surface, within the light line, and can be accessed without the use of a coupling prism or gratings. We investigated the emission spectra and angular distribution of the emission for probes located above and below the metal film to explore the interaction of fluorophores with Tamm plasmons and surface plasmons modes. Three probes were chosen with different overlap of the emission spectra with the Tamm modes. The fluorophores below the metal film coupled predominantly with the Tamm state and displayed more intense and only Tamm state-coupled emission (TSCE). Probes above the metal film display both surface plasmon-coupled emission (SPCE) and Tamm state-coupled emission. In contrast to SPCE, which shows only KR, P-polarized emission, the Tamm states can display both S- and P-polarized emission and can be populated using both RK and KR illuminations. The TSCE angle is highly sensitive to wavelength, which suggests the use of Tamm structures to provide both directional emission and wavelength dispersion. The combination of plasmonic and photonic structures with directional emission close to surface normal offers the opportunities for new design formats for clinical testing, portable devices, and other fluorescence-based applications.
Context-Aware Neural Voice Activity Detection Using Auxiliary Networks for Phoneme Recognition, Speech Enhancement and Acoustic Scene Classification (2019)

This paper proposes a novel fully neural network based voice activity detection (VAD) method that estimates whether each speech segment is speech or non-speech even in very low signal-to-noise ratio (SNR) environments. Our innovation is to improve context-awareness of speech variability by introducing multiple auxiliary networks into the neural VAD framework. While previous studies reported that phonetic-aware auxiliary features extracted from a phoneme recognition network can improve VAD performance, none examined other effective auxiliary features for enhancing noise robustness. Thus, this paper present a neural VAD that uses auxiliary features extracted from not only the phoneme recognition network but also a speech enhancement network and an acoustic scene classification network. The last two networks are expected to improve context-awareness even in extremely low SNR environments since they can extract de-noised speech awareness and noisy environment awareness. In addition, we expect that combining these multiple auxiliary features yield synergistic improvements in VAD performance. Experiments verify the superiority of the proposed method in very low SNR environments.

Driving vascular endothelial cell fate of human multipotent Isl1+ heart progenitors with VEGF modified mRNA (2013)

Distinct families of multipotent heart progenitors play a central role in the generation of diverse cardiac, smooth muscle and endothelial cell lineages during mammalian cardiogenesis. The identification of precise paracrine signals that drive the cell-fate decision of these multipotent progenitors, and the development of novel approaches to deliver these signals in vivo, are critical steps towards unlocking their regenerative therapeutic potential. Herein, we have identified a family of human cardiac endothelial intermediates located in outflow tract of the early human fetal hearts (OFT-ECs), characterized by coexpression of Isl1 and CD144/vWF. By comparing angiocrine factors expressed by the human OFT-ECs and non-cardiac ECs, vascular endothelial growth factor (VEGF)-A was identified as the most abundantly expressed factor, and clonal assays documented its ability to drive endothelial specification of human embryonic stem cell (ESC)-derived Isl1+ progenitors in a VEGF receptor-dependent manner. Human Isl1-ECs (endothelial cells differentiated from hESC-derived ISL1+ progenitors) resemble OFT-ECs in terms of expression of the cardiac endothelial progenitor- and endocardial cell-specific genes, confirming their organ specificity. To determine whether VEGF-A might serve as an in vivo cell-fate switch for human ESC-derived Isl1-ECs, we established a novel approach using chemically modified mRNA as a platform for transient, yet highly efficient expression of paracrine factors in cardiovascular progenitors. Overexpression of VEGF-A promotes not only the endothelial specification but also engraftment, proliferation and survival (reduced apoptosis) of the human Isl1+ progenitors in vivo. The large-scale derivation of cardiac-specific human Isl1-ECs from human pluripotent stem cells, coupled with the ability to drive endothelial specification, engraftment, and survival following transplantation, suggest a novel strategy for vascular regeneration in the heart.
Modélisation, caractérisation, simulation et interprétation du comportement thermique de la paroi à inertie faible d’une serre tunnel expérimentale à l’aide du quotient de Bibi CB (.) (2023)

La serre tunnel agricole classique est largement répandue dans les pays méditerranéens, malgré les insuffisances qu’elle présente, notamment la surchauffe pendant le jour et le refroidissement nocturne intense, qui parfois se traduit par l’inversion thermique interne. La serre chapelle habillée en verre est relativement plus performante, mais son évolution reste lente en raison de son coût d’investissement et son amortissement. Le comportement énergétique d’une serre a fait l’objet de plusieurs études et concerne globalement la nuit et afin de contribuer en une meilleure gestion climatique nous nous sommes proposé d’entreprendre une étude et analyse thermique de la paroi en fonction d’une modélisation. Lors de ce travail, nous avons mis au point un quotient nommé Bibi, qui permet de caractériser un matériau de couverture. Cet état d’évolution thermique est fonction du degré d’étanchéité de la couverture et de ses caractéristiques physiques, pour être transparente aux rayonnements solaires, absorbante et réfléchissante des rayonnements infrarouges émis par le sol, d’où l’effet de piégeage des radiations solaires autrement appelé ‘effet de serre’. Nous proposons dans cet article, la modélisation et l’analyse du comportement thermique de la paroi en polyéthylène ‘PE’ de la serre tunnel expérimentale.
<i>GOSR2</i>: a progressive myoclonus epilepsy gene (2016)

GOSR2-associated PME is associated with a homozygous mutation in GOSR2 (c.430G>T, p.Gly144Trp), a Golgi vesicle transport gene. The functional effect of this mutation is a loss of function that results in failure of the GOSR2 protein to localize to the cis-Golgi. The main clinical features of the GOSR2-associated PME are early-onset ataxia, areflexia, action myoclonus and seizures, scoliosis, elevated creatine kinase levels, relative preservation of cognitive function until the late stages of the disease, and relentless disease course. Severe photosensitive myoclonus is a common feature. GOSR2-associated PME is a rare disease with very few cases reported so far and it can be expected that the identification of further patients will contribute to expanding the phenotype and genotype of this condition.
Ion-Implanted Epitaxially Grown Gd2O3 on Silicon with Improved Electrical Properties (2020)

Abstract The effects of nitrogen incorporation by high-dose ion implantation in epitaxial gadolinium oxide (Gd 2 O 3 ) films on Si (111) followed by annealing have been investigated. The nitrogen content in the oxide layer was changed by altering the implantation dose. The presence of nitrogen incorporation on the Gd 2 O 3 layer was studied using Auger electron spectroscopy. Nitrogen incorporation is believed to occur by filling the oxygen vacancies or by removing hydroxyl group ions in Gd 2 O 3 . A maximum concentration of 11% was obtained for nitrogen in the interface between the silicon dioxide and Gd 2 O 3 layer and the implanted areas of the Gd 2 O 3 oxide layer after sputter depth profiling. The nitrogen distribution in the layer was found to be non-uniform. Nitrogen incorporation sharply reduced the leakage current and effectively suppressed the hysteresis. Leakage current was two orders lower compared with the pure Gd 2 O 3 .
Early-branching gut fungi possess a large, comprehensive array of biomass-degrading enzymes (2016)

The fungal kingdom is the source of almost all industrial enzymes in use for lignocellulose bioprocessing. We developed a systems-level approach that integrates transcriptomic sequencing, proteomics, phenotype, and biochemical studies of relatively unexplored basal fungi. Anaerobic gut fungi isolated from herbivores produce a large array of biomass-degrading enzymes that synergistically degrade crude, untreated plant biomass and are competitive with optimized commercial preparations from Aspergillus and Trichoderma. Compared to these model platforms, gut fungal enzymes are unbiased in substrate preference due to a wealth of xylan-degrading enzymes. These enzymes are universally catabolite-repressed and are further regulated by a rich landscape of noncoding regulatory RNAs. Additionally, we identified several promising sequence-divergent enzyme candidates for lignocellulosic bioprocessing.
Survival Impact of Planned Restaging and Early Surgical Salvage Following Definitive Chemoradiation for Locally Advanced Squamous Cell Carcinomas of the Oropharynx and Hypopharynx (2005)

For patients with T3/4 resectable nonlaryngeal head and neck cancers, planned clinical, radiographic, and pathologic restaging at 1 to 2 months after definitive RT provides the opportunity for early surgical salvage in those who fail at the primary site. This practice produces improved overall local control and survival rates compared with the literature reports for delayed attempted salvage with timing based on the findings of routine postradiation clinical surveillance. Future efforts may focus on the improved selection of patients who would be most likely to require early surgical intervention.
Diversity of <i>Cenococcum geophilum</i> isolates from serpentine and non-serpentine soils (2001)

Serpentine soils are characterized by a disproportionate level of Mg in relation to Ca and often contain phytotoxic levels of available Ni. Both of these factors may represent stresses to plants and fungi colonizing these soils. Ectomycorrhizal fungi play important roles in tree biology, and ecotypic adaptation in these fungi may be critical to the success of trees on serpentine soils. A collection of Cenococcum geophilum isolates was obtained from serpentine and non-serpentine soils by trapping isolates on the roots of Virginia pine (Pinus virginiana) seedlings. Restriction fragment length polymorphism (RFLP) analysis of the internal transcribed spacer region of ribosomal repeat exhibited certain common fragments among isolates and other fragments that varied in length. Additional polymorphic markers were obtained from PCR-amplified (β-tubulin gene fragments. UPGMA analysis of the RFLP data indicated that, with one possible exception, the serpentine isolates of C. geophilum are genetically more similar to each other than they are to the isolates from local or distant non-serpentine sites. AFLP analyses, sampling a greater number of loci across the genome, provided an even more distinct separation of the serpentine isolates from non-serpentine isolates. All serpentine isolates lacked a group I intron frequently found within the 18S ribosomal RNA gene in isolates of this species. The genetic divergence between serpentine and non-serpentine isolates may reflect adaptation to serpentine soil factors.
Reprogramming mouse embryo fibroblasts to functional islets without genetic manipulation (2017)

The constant quest for generation of large number of islets aimed us to explore the differentiation potential of mouse embryo fibroblast cells. Mouse embryo fibroblast cells isolated from 12- to 14-day-old pregnant mice were characterized for their surface markers and tri-lineage differentiation potential. They were subjected to serum-free media containing a cocktail of islet differentiating reagents and analyzed for the expression of pancreatic lineage transcripts. The islet-like cell aggregates (ICAs) was confirmed for their pancreatic properties via immunofluorecence for C-peptide, glucagon, and somatostain. They were positive for CD markers-Sca1, CD44, CD73, and CD90 and negative for hematopoietic markers-CD34 and CD45 at both transcription and translational levels. The transcriptional analysis of the ICAs at different day points exhibited up-regulation of islet markers (Insulin, PDX1, HNF3, Glucagon, and Somatostatin) and down-regulation of MSC-markers (Vimentin and Nestin). They positively stained for dithizone, C-peptide, insulin, glucagon, and somatostatin indicating intact insulin producing machinery. In vitro glucose stimulation assay revealed three-fold increase in insulin secretion as compared to basal glucose with insulin content being the same in both the conditions. The preliminary in vivo data on ICA transplantation showed reversal of diabetes in streptozotocin induced diabetic mice. Our results demonstrate for the first time that mouse embryo fibroblast cells contain a population of MSC-like cells which could differentiate into insulin producing cell aggregates. Hence, our study could be extrapolated for isolation of MSC-like cells from human, medically terminated pregnancies to generate ICAs for treating type 1 diabetic patients.
Wideband High-Resolution Frequency-to-Resistance Converter Based on Nonhomogeneous Magnetic-State Transitions (2020)

By harnessing the rich dynamics associated with nonhomogeneous magnetization configurations in confined nanostructures, the free layer of a magnetic tunnel junction (MTJ) can be forced, via a localized magnetic field, to transition between two magnetic states: the quasi-uniform and vortex states. Here, we demonstrate that such transitions can be driven back and forth to a dynamic equilibrium by exciting a MTJ with ac magnetic fields close to the resonant modes of the magnetic vortex. The frequency dependence of the dynamic-state transitions leads to a proposal for an alternative type of broadband analogue frequency-to-resistance converter (FRC). In this report, two quasilinear bands of the FRC are demonstrated: a relatively lower frequency converter operating between 200 and 350 MHz with 250-kHz resolution (\ensuremath{\sim}500 channels) and a higher frequency converter operating between 2.5 and 6 GHz with a 2.5-MHz resolution (\ensuremath{\sim}800 channels). The fact that a single CMOS-compatible nanoscale device can perform such a complex function over a multitude of frequency bands, with high-frequency resolution relative to that of conventional CMOS circuits, can enable the next generation of wireless communication circuit topologies.
Scintigraphic Detection of Pulmonary Emboli by Serial Positron Imaging of Inhaled<sup>15</sup>O-Labeled Carbon Dioxide (1978)

Inhaled radioactive carbon dioxide is retained in pulmonary blood distal to embolic obstruction and appears as an area of increased radioactivity that delineates the site and magnitude of the affected zone. The scintigraphic detection of pulmonary emboli by serial imaging of inhaled carbon dioxide labeled with cyclotron-produced 15O2 was evaluated in 27 patients undergoing conventional pulmonary ventilation/perfusion imaging and pulmonary arteriography. Fifteen patients proved to have pulmonary emboli on arteriography. Sensitivity (87%) and specificity (92%) rates for inhalation imaging were superior to those of conventional ventilation/perfusion imaging (P less than 0.05). Clearance of 15O2 activity was markedly delayed over embolized pulmonary segments (mean half time of 47.0 +/- 11.1 seconds [S.E.M.]) in comparison to normal segments (mean of 3.6 +/- 0.08 seconds; P less than 0.001). Pulmonary imaging by this method provides an approach to the detection of pulmonary emboli that is relatively sensitive and specific and permits analysis of persisting perfusion in embolized pulmonary segments. A major practical limitation, however, is the necessity of a nearby cyclotron.
SLSNet: Skin lesion segmentation using a lightweight generative\n adversarial network (2019)

The determination of precise skin lesion boundaries in dermoscopic images\nusing automated methods faces many challenges, most importantly, the presence\nof hair, inconspicuous lesion edges and low contrast in dermoscopic images, and\nvariability in the color, texture and shapes of skin lesions. Existing deep\nlearning-based skin lesion segmentation algorithms are expensive in terms of\ncomputational time and memory. Consequently, running such segmentation\nalgorithms requires a powerful GPU and high bandwidth memory, which are not\navailable in dermoscopy devices. Thus, this article aims to achieve precise\nskin lesion segmentation with minimum resources: a lightweight, efficient\ngenerative adversarial network (GAN) model called SLSNet, which combines 1-D\nkernel factorized networks, position and channel attention, and multiscale\naggregation mechanisms with a GAN model. The 1-D kernel factorized network\nreduces the computational cost of 2D filtering. The position and channel\nattention modules enhance the discriminative ability between the lesion and\nnon-lesion feature representations in spatial and channel dimensions,\nrespectively. A multiscale block is also used to aggregate the coarse-to-fine\nfeatures of input skin images and reduce the effect of the artifacts. SLSNet is\nevaluated on two publicly available datasets: ISBI 2017 and the ISIC 2018.\nAlthough SLSNet has only 2.35 million parameters, the experimental results\ndemonstrate that it achieves segmentation results on a par with the\nstate-of-the-art skin lesion segmentation methods with an accuracy of 97.61%,\nand Dice and Jaccard similarity coefficients of 90.63% and 81.98%,\nrespectively. SLSNet can run at more than 110 frames per second (FPS) in a\nsingle GTX1080Ti GPU, which is faster than well-known deep learning-based image\nsegmentation models, such as FCN. Therefore, SLSNet can be used for practical\ndermoscopic applications.\n
