Efficient tunable continuous-time integrated current-mode filter designs (2002)

Current-mode continous-time filters which exploit generic CMOS integrated circuits processes are very promising for high frequency applications, and have been investigated considerably recently. Current-mirror based current-mode circuits inherently have very few internal nodes; hence, they are subjected to minimum secondary parasitic poles effects. Current-mirror circuits also have potential advantages over classical g/sub m/-C circuit techniques in terms of lower power consumption, smaller operating voltage, and potentially higher bandwidth. In this paper we present an efficient tunable current-mirror technique in conjunction with a fine tuning resistive compensation strategy. A high Q current-mode second order bandpass, a fourth-order notch, and a third-order lowpass filter are presented.
A Novel Class of Generalized Chebyshev Low-Pass Prototype for Suspended Substrate Stripline Filters (1982)

A novel class of low-pass prototype filters having an equiripple passband response with three transmission zeros at infinity and the remainder at a finite real frequency is presented. The prototypes are synthesized using the alternating pole technique to obtain directly the even-mode or the odd-mode admittance and little accuracy is lost for prototypes up to degree 15. Tables of element values for commonly used specifications are included. The tables are useful for the design of TEM-mode microwave broad-band filters, diplexers, and multiplexers, particularly for a printed circuit form a realization. A design example of a low-pass microwave broad-band filter designed and constructed in suspended substrate stripline (SSS) configuration is given and experimental results are also presented.
Preparation of 2-BF<sub>3</sub>-Substituted 1,3-Dienes and Their Diels−Alder/Cross-Coupling Reactions (2005)

[reaction: see text] 2-BF3-substituted 1,3-butadienes with potassium and tetrabutylammonium counterions have been prepared in gram quantities from chloroprene via a simple synthetic procedure. The potassium salt of this new main group element substituted diene has been characterized by 1H, 13C, 11B, and 19F NMR. Diels-Alder reactions of these dienes with ethyl acrylate and methyl vinyl ketone are reported, as well as subsequent Pd-catalyzed cross-coupling reactions of those Diels-Alder adducts.
Superconducting materials (1984)

Superconductivity almost from its beginning has depended upon an interplay between materials research and condensed-matter physics. This interplay continues unabatedly today. The seemingly eternal fascination with the phenomenon of superconductivity lies in the spectacular electrical and magnetic properties exhibited by superconductors—zero resistance, the Meissner effect and the various macroscopic quantum aspects of superconductivity. Equally important to the practitioners of the trade is the fact that these striking electrical and magnetic properties make superconductivity easy to detect. In short, the evidence of superconductivity broadcasts itself, even when present only in trace amounts.

Reconstruction and Visualization of Multi-plane Images Based on Spatial Light Modulator (2010)

In order to achieve a real-time and visual observation of multi-plane images,a method using light-emitting materials is proposed.A 3D object can be divided into a series of 2D slices along the optical axis.With an efficient and fast 3D Gerchberg-Saxton algorithm,a computer-generated phase hologram is obtained and a numerical reconstruction is carried out on the computer.The process of 3D Gerchberg-Saxton algorithm is expounded,and the experiment for reconstruction and visualization of multi-plane images based on LC-SLM is conducted.With the grey level-phase curve of the LC-SLM,the computer-generated phase hologram is converted to gray-scale hologram,which is loaded to the LC-SLM to reconstruct the 3D light fields.The fluorescence characteristic of quantum dot materials is used to achieve the visualization of the light fields.Experimental results show that the optical reconstruction is in good agreement with numerical simulation.This technique is applicable in medicine,military,3D display,micromachining and micro-technology.

High-dose megestrol acetate in advanced or recurrent endometrial carcinoma: a Gynecologic Oncology Group Study. (1996)

High-dose MA is active in endometrial carcinoma, but appears to have no advantage over lower-dose progestins.
Potential Therapeutic Target Discovery by 2D-DIGE Proteomic Analysis in Mouse Models of Asthma (2011)

As asthma physiopathology is complex and not fully understood to date; it is expected that new key mediators are still to be unveiled in this disease. The main objective of this study was to discover potential new target proteins with a molecular weight >20 kDa by using two-dimensional differential in-gel electrophoresis (2D-DIGE) on lung parenchyma extracts from control or allergen-exposed mice (ovalbumin). Two different mouse models leading to the development of acute airway inflammation (5 days allergen exposure) and airway remodeling (10 weeks allergen exposure) were used. This experimental setting allowed the discrimination of 33 protein spots in the acute inflammation model and 31 spots in the remodeling model displaying a differential expression. Several proteins were then identified by MALDI-TOF/TOF MS. Among those differentially expressed proteins, PDIA6, GRP78, Annexin A6, hnRPA3, and Enolase display an increased expression in lung parenchyma from mice exposed to allergen for 5 days. Conversely, Apolipoprotein A1 was shown to be decreased after allergen exposure in the same model. Analysis on lung parenchyma of mice exposed to allergens for 10 weeks showed decreased calreticulin levels. Changes in the levels of those different mediators were confirmed by Western blot and immunohistochemical analysis. Interestingly, alveolar macrophages isolated from lungs in the acute inflammation model displayed enhanced levels of GRP78. Moreover, intratracheal instillation of anti-GRP78 siRNA in allergen-exposed animals led to a decrease in eosinophilic inflammation and bronchial hyperresponsiveness. This study unveils new mediators of potential importance that are up- and down-regulated in asthma. Among up-regulated mediators, GRP-78 appears as a potential new therapeutic target worthy of further investigations.

On the Development of the SIMon Finite Element Head Model (2003)

The SIMon (Simulated Injury Monitor) software package is being developed to advance the interpretation of injury mechanisms based on kinematic and kinetic data measured in the advanced anthropomorphic test dummy (AATD) and applying the measured dummy response to the human mathematical models imbedded in SIMon. The human finite element head model (FEHM) within the SIMon environment is presented in this paper. Three-dimensional head kinematic data in the form of either a nine accelerometer array or three linear CG head accelerations combined with three angular velocities serves as an input to the model. Three injury metrics are calculated: Cumulative strain damage measure (CSDM) - a correlate for diffuse axonal injury (DAI); Dilatational damage measure (DDM) - to estimate the potential for contusions; and Relative motion damage measure (RMDM) - a correlate for acute subdural hematoma (ASDH). During the development, the SIMon FEHM was tuned using cadaveric neutral density targets (NDT) data and further validated against the other available cadaveric NDT data and animal brain injury experiments. The hourglass control methods, integration schemes, mesh density, and contact stiffness penalty coefficient were parametrically altered to investigate their effect on the model's response. A set of numerical and physical parameters was established that allowed a satisfactory prediction of the motion of the brain with respect to the skull, when compared with the NDT data, and a proper separation of injury/no injury cases, when compared with the brain injury data. Critical limits for each brain injury metric were also established. Finally, the SIMon FEHM performance was compared against HIC15 through the use of NHTSA frontal and side impact crash test data. It was found that the injury metrics in the current SIMon model predicted injury in all cases where HIC15 was greater than 700 and several cases from the side impact test data where HIC15 was relatively small. Side impact was found to be potentially more injurious to the human brain than frontal impact due to the more severe rotational kinematics.
Learning to blend rankings (2010)

There have been great needs to develop effective methods for combining multiple rankings from heterogeneous domains into one single rank list arising from many recent web search applications, such as integrating web search results from multiple engines, facets, or verticals. We define this problem as Learning to blend rankings from multiple domains. We propose a class of learning-to-blend methods that learn a monotonically increasing transformation for each ranking so that the rank order in each domain is preserved and the transformed values are comparable across multiple rankings. The transformation learning can be tackled by solving a quadratic programming problem. The novel machine learning method for blending multiple ranking lists is evaluated with queries sampled from a commercial search engine and a promising improvement of Discounted Cumulative Gain has been observed.
Somatic rearrangement of T-cell antigen receptor gene in human T-cell malignancies. (1985)

A cDNA clone representing the gene encoding the beta chain of the human T-cell antigen receptor has been isolated recently. By using fragments of this cDNA as hybridization probes in Southern blot analysis of restriction endonuclease-digested genomic DNA, we have now examined the structure of the gene in DNA from 26 patients with acute leukemia and from 23 normal individuals. We have found that the T-cell antigen receptor gene has undergone somatic rearrangement in 14 of 14 patients with the phenotypic diagnosis of T-cell acute lymphoblastic leukemia. In this group of patients, similar patterns of rearrangement appear to occur in different patients. This finding suggests that there is either a limited repertoire of possible rearrangements or an association between the development of leukemia and specific patterns of rearrangement. DNA from 6 patients with acute myeloblastic leukemia, 6 patients with non-B, non-T acute lymphoblastic leukemia, and 23 nonleukemic individuals showed no rearrangement or polymorphism. One case of T-cell acute lymphoblastic leukemia, however, showed rearrangement of both the T-cell receptor beta chain and the constant region of the immunoglobulin gene. Studies with mixtures of DNAs from leukemic bone marrow cells and cultured skin fibroblasts, as well as with remission and relapse marrow DNAs from the same patients, indicate that this technique can detect 1% leukemic cells in a mixed population. In addition, DNA from the marrow of a patient in relapse contains a similar rearrangement to that found in the marrow sample taken at the time of diagnosis, which suggests that the original clone of leukemic cells was responsible for relapse. Our results indicate that assessment of rearrangement of the T-cell antigen receptor gene will be valuable in the diagnosis and management of leukemia and can be used to evaluate clonality in T-cell neoplasia.
In vivo validation of 4D flow MRI for assessing the hemodynamics of portal hypertension (2012)

This work demonstrates the feasibility of radial 4D flow MRI to quantify flow in the hepatic and splanchnic vasculature. Flow results agreed well with data reported in the literature, and conservation of mass provided indirect validation of flow quantification. Flow in patients with portal hypertensions demonstrated high variability, with patterns and magnitude consistent with the hyperdynamic state that commonly occurs in portal hypertension.
600V-class Super Junction MOSFET with High Aspect Ratio P/N Columns Structure (2008)

A Super Junction (SJ) MOSFET with high aspect ratio p/n columns structure has been proposed to improve the trade-off relationship between breakdown voltage and specific on-resistance (R <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">on</sub> )- We have proposed a new trench filling epitaxial growth technique to fabricate this structure. In this work, we tried to apply this method to 600 V-class SJ-MOSFETs. We succeeded in fabricating p/n columns structure of which the aspect ratio is 25. It shows that its R <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">on</sub> is lower than that of IGBTs, and is the lowest in the reported 600 V-class Si devices.
Fusacandins A and B; Novel Antifungal Antibiotics of the Papulacandin Class from Fusarium sambucinum. II. Isolation and Structural Elucidation. (1995)

Two novel antifungal compounds of the papulacandin class, named fusacandins A and B, have been isolated from Fusarium sambucinum. Each compound contains two units of galactose and one of glucose, the latter connected as a C-glycoside to an aromatic moiety. Fusacandin A is esterified at two sites with long-chain, unsaturated fatty acids and fusacandin B at only one site. The structures of the fusacandins were elucidated through analysis of mass spectral and 1-D and 2-D homonuclear and heteronuclear NMR data.
The psychology of emotion regulation: An integrative review (2008)

The present article reviews modern research on the psychology of emotion regulation. Emotion regulation determines the offset of emotional responding and is thus distinct from emotional sensitivity, which determines the onset of emotional responding. Among the most viable categories for classifying emotion-regulation strategies are the targets and functions of emotion regulation. The emotion-generating systems that are targeted in emotion regulation include attention, knowledge, and bodily responses. The functions of emotion regulation include satisfying hedonic needs, supporting specific goal pursuits, and facilitating the global personality system. Emotion-regulation strategies are classified in terms of their targets and functions and relevant empirical work is reviewed. Throughout this review, emotion regulation emerges as one of the most far-ranging and influential processes at the interface of cognition and emotion.
PVC Classification Algorithm Through Efficient R Wave Detection (2013)

Premature ventricular contractions are the most common of all arrhythmias and may cause more serious situation like ventricular fibrillation and ventricular tachycardia in some patients. Therefore, the detection of this arrhythmia becomes crucial in the early diagnosis and the prevention of possible life threatening cardiac diseases. Most methods for detecting arrhythmia require pp interval, or the diversity of P wave morphology, but they are difficult to detect the p wave signal because of various noise types. Thus, it is necessary to use noise-free R wave. So, the new approach for the detection of PVC is presented based on the rhythm analysis and the beat matching in this paper. For this purpose, we removed baseline wandering of low frequency band and made summed signals that are composed of two high frequency bands including the frequency component of QRS complex using the wavelet filter. And then we designed R wave detection algorithm using the adaptive threshold and window through RR interval. Also, we developed algorithm to classify PVC using RR interval. The performance of R wave and PVC detection is evaluated by using MIT-BIH arrhythmia database. The achieved scores indicate average detection rate of 99.76%, sensitivity of 99.30% and specificity of 98.66%; accuracy respectively for R wave and PVC detection.
Fronthaul dimensioning in C-RAN with web traffic for coordinated multipoint joint transmission (2015)

The use of centralized signal processing for dense urban mobile networks is gaining interest both in research and in industry. Gathering most of the base station functionalities in a processing pool would enable capacity sharing and the implementation of advanced techniques such as coordinated multi-point. Nevertheless, this puts stringent requirements on the network interconnecting the processing pool and the sites, especially in terms of maximum latency. In this paper, we provide results for dimensioning the fronthaul network that are obtained through modelling and discrete-event simulation. We model the full protocol stack for the network end-to-end in order to use realistic application-layer traffic and user behavior models. Our results show that the fronthaul latency should be kept below 0.6 ms in order to ensure optimal performances for the application.
Non‐verbal behaviour and the outcome of selection interviews (1980)

Non‐verbal behaviour (NVB) is an important component of the selection interview, yet it has received limited attention in the literature. In particular, little published research has examined NVB in real‐life interviews. A study is described in which 101 school‐leavers were interviewed by a four‐member panel for places on an engineering apprentice training scheme. The NVB of each candidate was categorized during the interview using a schedule of 10 classes of NVB divided into 30 components. When the interviews were grouped by outcome, i.e. accept, reserve, and reject, differences were found on several important classes of NVB. Alternative causal hypotheses are suggested for the observed relationship between NVB in the interview and the decision which was made.
