Stress-induced leakage current in ultrathin SiO2 films (1994)

A detailed study of the phenomena of high field stress-induced leakage current in thin oxide (5.0–8.0 nm) metal-oxide-semiconductor capacitors has been undertaken. The dependence of the stress leakage on the stressing electric field and the oxide thickness were obtained. The results show that the stressing voltage, rather than the electric field, is the dominant factor for determining stress-induced leakage. Furthermore, a threshold exists for the stressing voltage, below which no stress-induced leakage occurs. Since the voltage is directly related to the electron energy, these findings are consistent with a model where electrons of energy above a threshold are required to produce the observed stress leakage.

MR imaging-based texture analysis has the potential to differentiate squamous cell carcinoma from inverted papilloma and may, in the future, provide incremental information to the neuroradiologist.
A parametric study on the dynamic response of planar multibody systems with multiple clearance joints (2010)

A general methodology for dynamic modeling and analysis of multibody systems with multiple clearance joints is presented and discussed in this paper. The joint components that constitute a real joint are modeled as colliding bodies, being their behavior influenced by geometric and physical properties of the contacting surfaces. A continuous contact force model, based on the elastic Hertz theory together with a dissipative term, is used to evaluate the intrajoint contact forces. Furthermore, the incorporation of the friction phenomenon, based on the classical Coulomb’s friction law, is also discussed. The suitable contact-impact force models are embedded into the dynamics of multibody systems methodologies. An elementary mechanical system is used to demonstrate the accuracy and efficiency of the presented approach, and to discuss the main assumptions and procedures adopted. Different test scenarios are considered with the purpose of performing a parametric study for quantifying the influence of the clearance size, input crank speed, and number of clearance joints on the dynamic response of multibody systems with multiple clearance joints. Additionally, the total computation time consumed in each simulation is evaluated in order to test the computational accuracy and efficiency of the presented approach. From the main results obtained in this study, it can be drawn that clearance size and the operating conditions play a crucial role in predicting accurately the dynamic responses of multibody systems.

Some Results on Performances of Ceramic Tools (1960)

The tool life tests of various types of ceramic tools are carried out to investigate the machining performances, the compatibilities for materials cut and the wear processes. Some of the Japanese ceramic tools have been proved to be better than any foreign product applied for the present test. As far as continuous machining of cast irons is concerned, ceramic tools are substantially effective, and normally the production rate in terms of net machining time can be increased about four times compared with the case of carbide tools. However, for general steels, especially adhesive steels, ceramic tools have not been reliable yet from a practical point of view. It is most essential for steel cutting to increase the toughness of ceramics.
Synthesis of Mesoporous Silica Nanofibers with Controlled Pore Architectures (2004)

A one-phase route has been developed for the synthesis, under strongly acidic conditions with cationic surfactants, of mesoporous silica nanofibers with controlled internal pore architectures. The diameters of the fibers range from 50 to 250 nm, and the lengths are up to millimeters. The nanofibers can have either a longitudinal pore architecture, in which the pore channels are aligned parallel to the fiber axis, or a circular pore architecture, in which the pore channels are wound circularly around the fiber axis. The pore channels in both types of nanofibers are hexagonally packed. The cross sections of the nanofibers with longitudinal pore architectures are hexagonal and those of the nanofibers with circular pore architectures are circular. Systematic experiments were carried out in which the fraction of the nanofibers with circular pore architectures among the overall nanofibers was determined as a function of the growth temperature for hexadecyltrimethylammonium chloride (C16TMAC), hexadecyltrimethylammonium bromide (C16TMAB), hexadecylpyridinium chloride (C16PC), and hexadecylpyridinium bromide (C16PB) surfactants. Generally, lower temperatures produce nanofibers with longitudinal pore architectures and higher temperatures produce nanofibers with circular pore architectures. The transition temperatures for C16TMAC and C16TMAB surfactants are around 75 °C and those for C16PC and C16PB surfactants are around 55 °C. In addition, the one-phase synthesis was carried out with cationic surfactants of different tail lengths, including dodecyltrimethylammonium bromide (C12TMAB), tetradecyltrimethylammonium bromide (C14TMAB), and octadecyltrimethylammonium bromide (C18TMAB). No nanofibers are obtained from the synthesis with C12TMAB or C14TMAB surfactants, while greater than 95 wt % of the products from the synthesis with C18TMAB surfactant are nanofibers with longitudinal pore architectures in the temperature range of 40−90 °C. Furthermore, rhodamine 6G (Rh6G) dye molecules were incorporated during growth to make mesostructured nanofibers that are millimeters long and fluoresce uniformly along the entire length of the individual fiber.
Metal-packaged fibre Bragg grating strain sensors for surface-mounting onto spalled concrete wind turbine foundations (2015)

In this work, we demonstrate preliminary results for a hermetically sealed, metal-packaged fibre Bragg grating strain sensor for monitoring existing concrete wind turbine foundations. As the sensor is bolted to the sub-surface of the concrete, it is suitable for mounting onto uneven, wet and degraded surfaces, which may be found in buried foundations. The sensor was able to provide reliable measurements of concrete beam strain during cyclic three- and four- point bend tests. The strain sensitivity of the prototype sensor is currently 10 % of that of commercial, epoxied fibre strain sensors.
Experiments with computer vision methods for hand detection (2011)

For gesture and sign language recognition, hand shape and hand motion are the primary sources of information that differentiate one sign from another. So, building an efficient and reliable hand detector is an important step for recognizing signs and gesture. In this paper we evaluate four features for hand detection: color, temporal motion, gradient norm, and motion residue, and we explore the potential of these features for building a reliable hand detector. At first, we use these four features separately to identify where the hands are in each frame of our gesture videos. Then we evaluate different combinations of such features using weighted linear combination, so to build a more accurate hand detector. Experimental results show the relative performance of the four features in isolation and in different combinations, and demonstrate promising results for detectors that combine these features.
Seismic surface extraction using iterative Seismic DNA detection (2012)

A methodology for automated 3D horizon interpretation is presented. This methodology consists of two main parts. The first part is a detection step where a novel method inspired by DNA string detection, called Seismic DNA (Bakke et al. 2012), is used to detect seismic textures. The second part connects the detected textures into regions. An example of seismic textures can be e.g. a sorted sequence of seismic events. The detection step, described as iterative Seismic DNA, will be explained in the paper. The connection step is an extension of the Extrema technology (Borgos et al., 2003), and it generates spatial regions of similar seismic textures. The second step is described as extrema surface extraction.
A new computing rule for neuromorphic engineering (2015)

Neuromorphic engineering has helped to build a brain-inspired intelligent paradigm based on VLSI, and to promise a new application space on smart devices. Throughout most of the state-of-the-art neuromorphic systems, including analog, digital, the mixed one, as well as some other memristor-based systems, the dominated computing rule in neuron is simply based on the linear-superposition operation of the excitatory and inhibitory pre-synaptic inputs. However, recent discoveries in neuroscience field reveal that the post-synaptic potential at the soma cannot be directly achieved by linearly adding up all the pre-synaptic inputs, which indicates the prevailing computing rule in current neuromorphic systems is not very biologically plausible. In this paper, we introduce a new computing rule in neuron block, which nonlinearly depends on the pre-synaptic inputs. Besides the superposition operation, the membrane potential is also related to the product item of the excitatory and inhibitory inputs. Furthermore, we design a heuristic circuit for the bio-plausible computing rule, which is compatible with the crossbar structure based systems. These results provide a new insight into the role of inhibitory signals in the brain, which is very helpful to explore more reliable computing principles in future neuromorphic devices.
Convergent regulation of NF-IL6 and Oct-1 synthesis by interleukin-6 and retinoic acid signaling in embryonal carcinoma cells. (1993)

The nuclear signaling by the pleiotropic cytokine interleukin-6 (IL-6) has been investigated in human embryonal carcinoma cells and T cells. We show that Oct-1, a ubiquitously expressed octamer-binding protein known to be regulated posttranslationally, can also be regulated at the levels of mRNA and protein synthesis by IL-6 and by retinoic acid (RA) in human embryonal carcinoma cells. NF-IL6, an IL-6-inducible transcription factor of the C/EBP family, can confer this regulation and is itself regulated by both signals. The abundance and the molar ratios of the three forms of NF-IL6, corresponding to peptides initiated in frame from different AUGs of the same NF-IL6 mRNA species, are regulated by IL-6 and by RA. These results suggest that the two signal transduction pathways overlap in human embryonal carcinoma cells and that Oct-1 may be downstream of NF-IL6 in the shared regulatory cascade. Enhanced Oct-1 synthesis correlates with one of the functions of Oct-1, i.e., stimulation of adenovirus DNA replication. This provides an example of a possible functional consequence of IL-6 and RA signaling that is mediated by NF-IL6 and Oct-1 regulation.
A Randomized Prospective Study of Single Coil Versus Dual Coil Defibrillation in Patients with Ventricular Arrhythmias Undergoing Implantable Cardioverter Defibrillator Therapy (2003)

ICD implantation is standard therapy for malignant ventricular arrhythmias. The advantage of dual and single coil defibrillator leads in the successful conversion of arrhythmias is unclear. This study compared the effectiveness of dual versus single coil defibrillation leads. The study was a prospective, multicenter, randomized study comparing a dual with a single coil defibrillation system as part of an ICD using an active pectoral electrode. Seventy-six patients (64 men, 12 women; age 61 +/- 11 years) were implanted with a dual (group 1, n = 38) or single coil lead system (group 2,n = 38). The patients represented a typical ICD cohort: 60% presented with ischemic cardiomyopathy as their primary cardiac disease, the mean left ventricular ejection fraction was 0.406 +/- 0.158. The primary tachyarrhythmia was monomorphic ventricular tachyarrhythmia in 52.6% patients and ventricular fibrillation in 38.4%. There was no significant difference in terms of P and R wave amplitudes, pacing thresholds, and lead impedance at implantation and follow-up in the two groups. There was similarly no difference in terms of defibrillation thresholds (DFT) at implantation. Patients in group 1 had an average DFT of 10.2 +/- 5.2 J compared to 10.3 +/- 4.1 J in Group 2, P = NS. This study demonstrates no significant advantage of a dual coil lead system over a single coil system in terms of lead values and defibrillation thresholds. This may have important bearing on the choice of lead systems when implanting ICDs.

Oxygen Donor Stabilized Alkaline Earth Metal Iodides (2003)

Alkaline earth metal iodides show ionic behavior in water, but their bonding situation is not that clear in less polar solvents. The alkaline earth metal iodide adducts, i.e. [MI2(thf)5](M = Sr and Ba), [CaI2(L)4] (L = thf, H2O), [Ba(OH)I(H2O)4] and [CaI2(dme)(diglyme)] (dme = dimethoxy ethane; diglyme = diethylene glycol dimethyl ether) are presented in this context and their bonding situation is discussed.
Clinical breast cancer and estrogen (2003)

The remarkable generation of scores of increasingly sophisticated mouse models of mammary cancer over the past two decades has provided tremendous insights into molecular derangements that can lead to cancer. The relationships of these models to human breast cancer, however, remain problematic. Recent advances in genomic technologies offer significant opportunities to identify critical changes that occur during cancer evolution and to distinguish in a complex and comprehensive manner the key similarities and differences between mouse models and human cancer. Comparisons between mouse and human tumors are being performed using comparative genomic hybridization, gene expression profiling, and proteomic analyses. The appropriate use of genetically engineered mouse models of mammary cancer in preclinical studies remains an important challenge which may also be aided by genomic technologies. Genomic approaches to cancer are generating huge datasets that represent a complex system of underlying networks of genetic interactions. Mouse models offer a tremendous opportunity to identify such networks and how they relate to human cancer. The challenge of the future remains to decipher these networks in order to identify the genetic nodes of oncogenesis that may be important targets for chemoprevention and therapy.
Robotic Computing on FPGAs: Current Progress, Research Challenges, and Opportunities (2022)

Robotic computing has reached a tipping point, with a myriad of robots (e.g., drones, self-driving cars, logistic robots) being widely applied in diverse scenarios. The continuous proliferation of robotics, however, critically depends on efficient computing substrates, driven by real-time requirements, robotic size-weight-and-power constraints, cybersecurity considerations, and dynamically changing scenarios. Within all platforms, FPGA is able to deliver both software and hardware solutions with low power, high performance, reconfigurability, reliability, and adaptivity characteristics, serving as the promising computing substrate for robotic applications. This paper highlights the current progress, design techniques, challenges, and open research challenges in the domain of robotic computing on FPGAs.
FBE, a Foundation for Pipeline Corrosion Coatings (2000)

Abstract The key to a successful pipeline anti-corrosion program is an effective protective coating system comprised of proven, high-quality coating materials, consistently applied to exacting specifications. Mill applied fusion-bonded epoxy (FBE) has been, and continues to be, the coating of choice for many pipeline operating companies since the 1960s. As the use of such coatings has expanded, much research has been conducted in an effort to improve the physical, chemical, and economic aspects of these coatings. New advancements in FBE coating technology have led to the availability of dramatically improved coating materials and systems to address specific pipeline construction needs and to enable the coating to function under a wide variety of corrosive conditions. In this paper, a review of FBE pipe coatings will be presented, progressing from their early years to the next-generation materials under development today. FBE coating solutions for the corrosion mitigation of pipeline systems will be discussed, ranging from its use as a stand-alone external coating, to the foundation layer of a three-layer coating, to a stand alone internal lining.
Well clear recovery for detect and avoid (2016)

The purpose of Detect and Avoid (DAA) is to maintain Well Clear between ownship and any potential intruders. One sub-function of a DAA system is the human interface where aural alerts and visual guidance for maintaining Well Clear are displayed to the pilot. However, situations can occur where Well Clear is lost. In such situations, the visual guidance must change from displaying guidance meant to maintain Well Clear to guidance that aids the pilot to recover Well Clear. This paper describes a concept for displaying guidance to maintain and recover Well Clear. A distinguishing feature is that the generated guidance is continuous before and after loss of Well Clear, i.e. no discontinuity occurs in the guidance when crossing the Well Clear boundary. The concept was evaluated using simulations and flight-testing, and some of the results are discussed here.
New Criteria Based on ST Changes in 12‐Lead Surface ECG to Detect Proximal versus Distal Right Coronary Artery Occlusion in a Case of Acute Inferoposterior Myocardial Infarction (2004)

The new criterion based on the ST changes in V1 lead is highly accurate in detecting the location of occlusion in the RCA compared to the criteria based only on ST changes in lateral leads. The use of this criterion might increase the accuracy of ECG-based identification of myocardial involvement in acute inferoposterior MI.

SCAU-Net: Spatial-Channel Attention U-Net for Gland Segmentation (2020)

With the development of medical technology, image semantic segmentation is of great significance for morphological analysis, quantification, and diagnosis of human tissues. However, manual detection and segmentation is a time-consuming task. Especially for biomedical image, only experts are able to identify tissues and mark their contours. In recent years, the development of deep learning has greatly improved the accuracy of computer automatic segmentation. This paper proposes a deep learning image semantic segmentation network named Spatial-Channel Attention U-Net (SCAU-Net) based on current research status of medical image. SCAU-Net has an encoder-decoder-style symmetrical structure integrated with spatial and channel attention as plug-and-play modules. The main idea is to enhance local related features and restrain irrelevant features at the spatial and channel levels. Experiments on the gland dataset GlaS and CRAG show that the proposed SCAU-Net model is superior to the classic U-Net model in image segmentation task, with 1% improvement on Dice score and 1.5% improvement on Jaccard score.
New Role of CO2 as a Selective Agent in Palladium-Catalyzed Reductive Ullmann Coupling with Zinc in Water (2003)

Carbon dioxide was found to promote the palladium-catalyzed zinc-mediated reductive Ullmann coupling of aryl halides. In the presence of carbon dioxide, Pd/C, and zinc, various aromatic halides including less reactive aromatic chlorides were coupled to give the corresponding homocoupling products in good yields.
Localization of Gonadotropin Releasing Hormone (GnRH) Within the Bovine Hypothalamus11 (1977)

The distribution of immunoreactive gonadotropin releasing hormone (GnRH) was determined within regions of the bovine hypothalamus. Fresh, frozen bovine hypothalami were cut in serial sections (500 µ) in the horizontal, frontal or sagittal planes. All sections were individually extracted with 2N acetic acid and the 10,000 × g supernatant lyophilized. Extracts were reconstituted in water and radioimmunoassayed for GnRH. In the frontal plane, GnRH concentration was localized in a peak centered at the midpoint of the pituitary stalk and extending 5 mm anterior and posterior. A small (18 percent of major peak) but significant (P<0.05) peak of GnRH was localized 8 to 10 mm anterior to the midpoint of the pituitary stalk. In the sagittal plane, GnRH was localized in a symmetrical peak centered at the midpoint of the stalk and extending 3.5 mm from the midline. In the horizontal plane, peak GnRH concentration was found in the pituitary stalk and a smaller quantity (5 percent of major peak) was found 3.5 mm dorsal to the ventral surface of the median eminence. Luteinizing hormone releasing activity of these extracts was estimated by evaluating their ability to release LH from bovine anterior pituitary cells in primary culture. Areas of greatest bioactivity corresponded to areas of greatest immunoreactive GnRH concentration. The results suggest that GnRH in the bovine hypothalamus is confined to the pituitary stalk and a rostral hypothalamic region. In addition, areas of LH releasing activity and immunologically detectable GnRH concentrations coincide.
