Modeling manufacturing process variation for design and test (2011)

For process nodes 22nm and below, a multitude of new manufacturing solutions have been proposed to improve the yield of devices being manufactured. With these new solutions come an increasing number of defect mechanisms. There is a need to model and characterize these new defect mechanisms so that (i) ATPG patterns can be properly targeted, (ii) defects can be properly diagnosed and addressed at design or manufacturing level. This presentation reviews currently available defect modeling and test solutions and summarizes open issues faced by the industry today. It also explores the topic of creating special test structures to expose manufacturing process parameters which can be used as input to software defect models to predict die specific defect locations for better targeting of test.
Rate-distortion optimized streaming from the edge of the network (2004)

This paper addresses the problem of streaming packetized media over a lossy packet network through an intermediate proxy server to a client, in a rate-distortion optimized way. The proxy, located at the junction of the backbone network and the last hop to the client, coordinates the communication between the media server and the client using hybrid receiver/sender-driven streaming in a rate-distortion optimization framework. The framework enables the proxy to determine at every instant which packets, if any, it should either request from the media server or retransmit directly to the client, in order to meet a constraint on the average transmission rate while minimizing the average end-to-end distortion. Performance gains of up to 1.5 dB and up to 4 dB are observed over rate-distortion optimized sender-driven systems for the case when the last hop is wireline and wireless, respectively.
Heteroepitaxial molecular beam epitaxial InSb and room temperature operation of its metal-insulator-semiconductor field-effect transistors (1986)

Calculations are shown to investigate the possibility of modulating the channel conductance of InSb field-effect transistors (FET’s) at 300 K. Molecular beam epitaxy (MBE) grown InSb metal-insulator-semiconductor field-effect transistors (MISFET’s) were successfully fabricated and exhibited room temperature operation.
Correlation of Surface Wettability and Corrosion Rate for Benzotriazole‐Treated Copper (1992)

The wetting characteristics of copper surfaces, with and without an exposure to benzotriazole and benzotriazole derivatives, have been investigated by dynamic contact angle measurements. The results were compared to corrosion rates measured on the same samples by electrochemical techniques. The experiments show that the inhibitor's effectiveness for corrosion reduction is not reflected well by the advancing contact angles of water. However, a good correlation is observed with the parameters obtained on a previously wetted surface, such as receding contact angles and the work of surface rewetting. These parameters were obtained through repeated dipping experiments. The details of the wetting process are evaluated quantitatively as an excess work of adhesion and can be used as an alternate measure of the expected corrosion resistance for differently treated surfaces.
Rivulet Formation in Surface-Water Flow on an Airfoil in Rain (1999)

The location of the onset of rivulet formation in the surface-water flow over a wing with a NACA 4412 airfoil in rainfall rates of 50-160 mm/h is calculated and compared with wind-tunnel experiments. A model is presented in which rivulets form when the surface-tension shear stress between the liquid and the airfoil surface equals the interface shear stress caused by aerodynamic forces on the liquid due to air motion. Surface-tension shear stresses are ohtained from measurements of surface tension and contact angle at the solid-water interface. Aerodynamic shear stresses are calculated by solution of Reynolds-averaged Navier-Stokes equations
Percutaneous aortic valve replacement (part 2): Miniaturization of the delivery system based on the novel temporary valve technology (2009)

Percutaneous aortic valve replacement remains an investigational procedure challenged by multiple key issues. In part 1 of this 2 part series, the issue of precise placement of the percutaneous aortic valve was addressed by a novel design of a delivery and deployment system. The design and use of a hemodynamics supporting temporary aortic valve was highlighted, which can stabilize the hemodynamic and local flow conditions for a more controlled and precise placement of the percutaneous aortic valve. In this part 2 study, the issue of vascular access complications is addressed. The current large French size catheter systems can cause significant vascular injuries; the catheter diameter must be reduced for this procedure to be safe and routine. The hemodynamic support of the temporary aortic valve system allows for the formulation of a novel approach to reduce the catheter-delivery system. The miniaturization strategies consist of pretreatment of the aortic annulus and assembly of the percutaneous aortic valve apparatus in a piecemeal fashion of smaller components. Each component would, therefore, require a smaller diameter delivery catheter. The combined strategies as described in this 2 part series aim at realizing the percutaneous aortic valve replacement as a routine, fully percutaneous and cath lab-based.
A Brief Review of Facial Emotion Recognition Based on Visual Information (2018)

Facial emotion recognition (FER) is an important topic in the fields of computer vision and artificial intelligence owing to its significant academic and commercial potential. Although FER can be conducted using multiple sensors, this review focuses on studies that exclusively use facial images, because visual expressions are one of the main information channels in interpersonal communication. This paper provides a brief review of researches in the field of FER conducted over the past decades. First, conventional FER approaches are described along with a summary of the representative categories of FER systems and their main algorithms. Deep-learning-based FER approaches using deep networks enabling "end-to-end" learning are then presented. This review also focuses on an up-to-date hybrid deep-learning approach combining a convolutional neural network (CNN) for the spatial features of an individual frame and long short-term memory (LSTM) for temporal features of consecutive frames. In the later part of this paper, a brief review of publicly available evaluation metrics is given, and a comparison with benchmark results, which are a standard for a quantitative comparison of FER researches, is described. This review can serve as a brief guidebook to newcomers in the field of FER, providing basic knowledge and a general understanding of the latest state-of-the-art studies, as well as to experienced researchers looking for productive directions for future work.
Syntheses of Potentially Antineoplastic Amides and Esters of <i>N</i>‐[<i>N</i>'‐(2‐Chloroethyl)‐<i>N</i>'‐nitrosocarbamoyl]amino Acids, II (1984)

Abstract Syntheses of N ‐[ N '‐(2‐chloroethyl)‐ N '‐nitrosocarbamoyl]amino acid amides and esters as potential antineoplastic substances are reported. N ‐[ N '‐(2‐chloroethyl)‐ N '‐nitrosocarbamoyl]amino acids (with the exception of the glycine derivative) were prepared by reaction of 2‐chloroethyl isocyanate with the sodium salt of an amino acid in a heterogenous medium followed by nitrosation with sodium nitrite under acidic conditions. Condensation with amines or alcohols using 1,1‐carbonyldiimidazole led to the amides or esters.
3′ RNA Elements in Hepatitis C Virus Replication: Kissing Partners and Long Poly(U) (2007)

The hepatitis C virus (HCV) genomic RNA possesses conserved structural elements that are essential for its replication. The 3' nontranslated region (NTR) contains several of these elements: a variable region, the poly(U/UC) tract, and a highly conserved 3' X tail, consisting of stem-loop 1 (SL1), SL2, and SL3. Studies of drug-selected, cell culture-adapted subgenomic replicons have indicated that an RNA element within the NS5B coding region, 5BSL3.2, forms a functional kissing-loop tertiary structure with part of the 3' NTR, 3' SL2. Recent advances now allow the efficient propagation of unadapted HCV genomes in the context of a complete infectious life cycle (HCV cell culture [HCVcc]). Using this system, we determine that the kissing-loop interaction between 5BSL3.2 and 3' SL2 is required for replication in the genotype 2a HCVcc context. Remarkably, the overall integrity of the 5BSL3 cruciform is not an absolute requirement for the kissing-loop interaction, suggesting a model in which trans-acting factor(s) that stabilize this interaction may interact initially with the 3' X tail rather than 5BSL3. The length and composition of the poly(U/UC) tract were also critical determinants of HCVcc replication, with a length of 33 consecutive U residues required for maximal RNA amplification. Interrupting the U homopolymer with C residues was deleterious, implicating a trans-acting factor with a preference for U over mixed pyrimidine nucleotides. Finally, we show that both the poly(U) and kissing-loop RNA elements can function outside of their normal genome contexts. This suggests that the poly(U/UC) tract does not function simply as an unstructured spacer to position the kissing-loop elements.
An improved dynamic power distribution control scheme for PWM controlled converter modules (2003)

PWM gain scheduling control is applied to a load-sharing system driven by different line sources whose voltages vary over a wide range. This system can distribute total output current among converter modules with various current ratings. The large-signal behavior of such a system is verified, based primarily on computer simulation. Based on the small-signal analysis, the design procedure for the current and voltage error amplifiers is shown in detail. The system relative stability is investigated to ensure that the performance requirements are satisfied. It is pointed out that the loop-gain function in a multiple-loop system is not as useful as that in a single-loop system. In other words. the current and voltage error amplifiers or compensators need to be selected based on the system characteristic equation, which is uniquely defined for a system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Dual-camera design for coded aperture snapshot spectral imaging (2015)

Coded aperture snapshot spectral imaging (CASSI) provides an efficient mechanism for recovering 3D spectral data from a single 2D measurement. However, since the reconstruction problem is severely underdetermined, the quality of recovered spectral data is usually limited. In this paper we propose a novel dual-camera design to improve the performance of CASSI while maintaining its snapshot advantage. Specifically, a beam splitter is placed in front of the objective lens of CASSI, which allows the same scene to be simultaneously captured by a grayscale camera. This uncoded grayscale measurement, in conjunction with the coded CASSI measurement, greatly eases the reconstruction problem and yields high-quality 3D spectral data. Both simulation and experimental results demonstrate the effectiveness of the proposed method.
Mitochondrial abnormalities in ageing macular photoreceptors. (2001)

The results show that mitochondrial DNA deletions and cytochrome c oxidase-deficient cones accumulate in the ageing retina, particularly in the foveal region. These defects may contribute to the changes in macular function observed in ageing and age-related maculopathy.
Comparison of transmission acquisition approaches for SPECT nonuniform attenuation compensation (1998)

This study compared two approaches for acquiring transmission computed tomography (TCT) data for SPECT nonuniform attenuation compensation. One approach, which has been implemented in commercial SPECT systems, acquires the TCT and SPECT data simultaneously using a scanning transmission line source, dual head SPECT system and parallel beam collimation (PB-sim). The other approach acquires the TCT and SPECT data sequentially using long focus, off-set fan beam collimation with a non-scanning line source and a triple head system (FB-seq). The two systems were compared based on: (a) the noise level of the TCT projection data, (b) the spatial resolution of the TCT projection data, and (c) the quality of reconstructed TCT and SPECT images of a thorax phantom. For the thorax phantom data a fast TCT scan (2 min.) was used and total scan time (TCT and SPECT) was the same for the two systems. The results from the TCT noise measurements showed that for the source activities used here (400 mCi for PB-sim, 56 mCi for FB-seq), PB-sim had higher count density in the lung region whereas FB-seq had higher in the heart and liver regions. The measured TCT spatial resolution for the two systems was comparable in the axial direction but was superior with FB-seq in the transaxial direction. The resolution difference was apparent in the reconstructed TCT images. These results suggest that the FB-seq system offers a viable approach for TCT acquisition and one that compares favorably with current commercial approaches based on TCT noise, resolution and reconstructed image quality.
Effects of Caffeine in Parkinson's Disease: From Neuroprotection to the Management of Motor and Non-Motor Symptoms (2010)

Parkinson's disease (PD) is the second most common neurodegenerative disorder affecting approximately 1% of the population older than 60 years. Classically, PD is considered to be a motor system disease and its diagnosis is based on the presence of a set of cardinal motor signs (rigidity, bradykinesia, rest tremor) that are consequence of a pronounced death of dopaminergic neurons in the substantia nigra pars compacta. Nowadays there is considerable evidence showing that non-dopaminergic degeneration also occurs in other brain areas which seems to be responsible for the deficits in olfactory, emotional and memory functions that precede the classical motor symptoms in PD. The present review attempts to examine results reported in epidemiological, clinical and animal studies to provide a comprehensive picture of the antiparkinsonian potential of caffeine. Convergent epidemiological and pre-clinical data suggest that caffeine may confer neuroprotection against the underlying dopaminergic neuron degeneration, and influence the onset and progression of PD. The available data also suggest that caffeine can improve the motor deficits of PD and that adenosine A2A receptor antagonists such as istradefylline reduces OFF time and dyskinesia associated with standard 'dopamine replacement' treatments. Finally, recent experimental findings have indicated the potential of caffeine in the management of non-motor symptoms of PD, which do not improve with the current dopaminergic drugs. Altogether, the studies reviewed provide strong evidence that caffeine may represent a promising therapeutic tool in PD, thus being the first compound to restore both motor and non-motor early symptoms of PD together with its neuroprotective potential.
Halogen‐Bond‐Templated [2+2] Photodimerization in the Solid State: Directed Synthesis and Rare Self‐Inclusion of a Halogenated Product (2016)

A ditopic halogen-bond acceptor organizes a diiodooctafluorostilbene for a [2+2] photodimerization reaction to take place between two stilbene molecules in the solid state. The resultant cyclobutane product is functionalized with halogen atoms and undergoes self-assembly to form a channel-type host-guest compound that exhibits a very rare form of self-inclusion.
Research progress of B7-H4,tumor and T cell immunity (2011)

Tumor is a malignant disease with high incidence and mortality and poor prognosis,which is harmful to human's health. B7-H4 ,a new member of B7 family, is a negative regulatory factor of T cell immune response. It can negatively regulate T cell immune response by inhibiting T cell proliferation and activation, cytokine secretion, and cell cycle progression. It is overexpressed in malignant tumor tissues,has an important relationship with tumor formation and immunity. It can be used as a new target for the diagnosis and treatment of tumor.

Under the Rainbow (1976)

This ethnographic study of the Panare Indians of Venezuela is the first extensive look at a tribe of this region of the Amazonia. It is an important book not only because it delves into the myth-filled Panare culture, but also because the author has used a modified version of the structural analysis of Claude Lévi-Strauss in examining the Panare. Lévi-Strauss applied his method of structural analysis to the mythology of many societies in Amazonia, but never to any single society. Jean-Paul Dumont has filled that gap and has shown how the approach works in practice when applied to the intensive study of a single, small-scale culture. His book significantly expands the discussion of the strengths and weaknesses of the method. The work deals specifically with the implicit mythology of the Panare and is concerned with the symbolic activities manifested in the daily behavior of this group. The analysis of the symbolism, explains Dumont, allows for the discovery of the conceptual system through which the Panare conceive of themselves. The study is organized into two parts: a presentation of the data and an analysis. The presentation includes a geographical and historical account of the Panare and a general ethnological profile. The analysis is organized into the conceptual categories of inhabited space, time, astrosexuality, hearing, and taste. A concluding chapter summarizes the analysis. Under the Rainbow will be of interest and of value not only to anthropologists but also to linguists, philosophers, psychologists, and others interested in the general intellectual movement represented by French structuralism. The fieldwork for Under the Rainbow was conducted in Venezuelan Guiana from September 1967 to July 1969.
Fatty acid alterations and polymyxin B binding by lipopolysaccharides from Pseudomonas aeruginosa adapted to polymyxin B resistance (1989)

Lipopolysaccharides were extracted from freeze-dried cells of Pseudomonas aeruginosa PAO1 (polymyxin B susceptible), isolate A (polymyxin B resistant), and isolate A-reverted (polymyxin B intermediate resistance) by either the phenol-chloroform-petroleum ether or the modified phenol-water method. Isolate A and isolate A-reverted had drastic losses of 2-hydroxydodecanoic acid and significant decreases in 3-hydroxydecanoic acid. Concentrations of amide-linked 3-hydroxydecanoic acid were similar in all three strains. Minor alterations were noted in the composition of 3-deoxy-D-manno-2-octulosonic acid, heptose, phosphate, neutral sugars, and amino compounds. The concentrations of rhamnose in isolate A and of rhamnose and glucose in isolate A-reverted were significantly different from those in PAO1. Trace amounts of mannose and other minor unidentified carbohydrates were detected in all strains. Polymyxin B included in isolate. A growth medium complexed with lipopolysaccharides and remained bound throughout purification. PAO1 lipopolysaccharides bound more polymyxin B than did isolate A lipopolysaccharides. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis indicated minor differences in smooth- and rough-form lipopolysaccharides of the different strains. We propose that loss of hydroxy fatty acids from lipopolysaccharides perturbs outer membrane hydrophobicity and is a contributing factor to polymyxin B adaptive resistance.
Prospective evaluation of methylated <i>SEPT9</i> in plasma for detection of asymptomatic colorectal cancer (2013)

Optimal frequency measurements with maximally correlated states (1996)

We show how maximally correlated states of N two-level particles can be used in spectroscopy to yield a frequency uncertainty equal to (NT${)}^{\mathrm{\ensuremath{-}}1}$, where T is the time of a single measurement. From the time-energy uncertainty relation we show that this is the best precision possible. We rephrase these results in the language of particle interferometry and obtain a state and detection operator which can be used to achieve a phase uncertainty exactly equal to the 1/N Heisenberg limit, where N is the number of particles used in the measurement.
Expression of Angiogenic Factors During Acute Coronary Syndromes in Human Type 2 Diabetes (2004)

Inadequate angiogenic response to ischemia in diabetic myocardium could result in poor collateral formation. Because hypoxia-inducible factor (HIF)-1alpha is a transcriptional activator of vascular endothelial growth factor (VEGF) and is critical for initiating angiogenic responses to hypoxia, we investigated the expression of HIF-1alpha and VEGF in specimens of human heart tissue to elucidate the molecular responses to myocardial ischemia in diabetic patients during unstable angina. Moreover, accumulation of a marker of protein nitration nitrotyrosine, as well as the superoxide anion (O(2)(-)) levels and inducible nitric oxide synthase (iNOS), were evaluated. Ventricular biopsy specimens from 15 type 2 diabetic and 14 nondiabetic patients presenting with unstable angina (ischemic group) and from 20 patients (11 type 2 diabetic and 9 nondiabetic patients) who underwent coronary bypass surgery without angina within the preceding 10 days (control group) were collected during coronary bypass surgery. Nondiabetic patients had higher HIF-1alpha and VEGF expressions compared with diabetic patients (P < 0.001). As compared with nondiabetic specimens, diabetic specimens showed higher levels of both iNOS mRNA and protein levels (P < 0.001) associated with the highest tissue levels of nitrotyrosine and O(2)(-) (P < 0.001). Diabetes is associated with increased myocardial tissue levels of iNOS, O(2)(-), and nitrotyrosine and reduced expression of myocardial angiogenesis factors during ischemia.
