Prognostic significance of osteopontin expression in early-stage non-small-cell lung cancer (2005)

Osteopontin (OPN) is a multifunctional protein, which has recently been shown to be linked to tumorigenesis, progression and metastasis in different malignancies. Since non-small-cell lung cancer (NSCLC)'s prognosis remains bad, with few predictors of outcome, the purpose of this study was to evaluate if OPN might be involved in NSCLC's biology and therefore represent a prognostic marker and a target for new therapeutic trials. Immunohistochemistry was used to detect OPN expression, evaluated as percentage of neoplastic cells with cytoplasmic immunoreactivity, in a wide cohort of patients with stage I NSCLC (136 cases). The median value of this series (20% of positive cells) was used as the cutoff value to distinguish tumours with low (<20%) from tumours with high (> or =20%) OPN expression. A statistically significant correlation between high levels of OPN and shorter overall (P = 0.034) and disease-free (P = 0.011) survival in our patients was shown. Our results support the hypothesis that high OPN expression is a significantly unfavourable prognostic factor for the survival of patients with stage I NSCLC. This conclusion has notable importance in terms of the biological characterization of early-stage tumours and therapeutic opportunities.
Crystal Structure of Mouse H2-M (1998)

H2-M (HLA-DM in humans) resides in an acidic endosomal compartment, where it facilitates the loading of antigenic peptides into the peptide-binding groove of class II MHC. The crystal structure of a soluble form of H2-M has been solved to 3.1 A resolution, revealing a heterodimer with structural similarities to the MHC family of proteins. In contrast to its antigen-presenting cousins, the membrane distal alpha helices of H2-M pack closely together, occluding most of the binding groove except for a single large pocket near the center. The structure of H2-M has several unique features that may play a role in its function as a molecular chaperone and peptide exchange factor.
Study on classification model based on relevance vector machine with genetic algorithm (2010)

A novel classification method based on relevance vector machine with genetic algorithm is presented in the paper. In the model, genetic algorithm is applied to gain the suitable training parameters of relevance vector machine. State classification of roll bearing is applied to testify the classification ability of the proposed method, and state classification data of roll bearing are given. The experimental results show that relevance vector machine with genetic algorithm has higher classification accuracy than back-propagation neural network and support vector machine.
Double auction protocols for resource allocation in grids (2005)

In this paper we propose the double auction allocation model for grids, and three double auction protocols for resource allocation: Preston-McAfee Double Auction Protocol (PMDA), threshold price double auction protocol (TPDA) and continuous double auction protocol (CDA). We study these protocols in terms of economic efficiency and system performance. The results show that CDA protocol is better from both resource's and user's perspective providing high resource utilization.
Who Are Like-Minded: Mining User Interest Similarity in Online Social Networks (2021)

In this paper, we mine and learn to predict how similar a pair of users’ interests towards videos are, based on demographic, social and interest information of these users. We use the video access patterns of active users as ground truth. We adopt tag-based user profiling to establish this ground truth. We then show the effectiveness of the different features, and their combinations and derivatives, in predicting user interest similarity, based on different machine-learning methods for combining multiple features. We propose a hybrid tree-encoded linear model for combining the features, and show that it out-performs other linear and tree-based models. Our methods can be used to predict user interest similarity when the ground-truth is not available, e.g. for new users, or inactive users whose interests may have changed from old access data, and is useful for video recommendation.
Combination of stereo, motion and rendering for 3D footage display (2002)

The emergence of a new generation of 3D auto stereoscopic displays is driving the requirement for multi-baseline images. The dominant form of this display technology requires multiple views of the same scene, captured at a single, instance in time along a common baseline in order to project stereoscopic images to the viewer. The direct acquisition of multiple views (typically 8 or 16 for the current generation of such displays) is problematic due to the difficulty of configuring, calibrating and controlling multiple cameras simultaneously. This paper describes a technique that alleviates these problems by generating the required views from binocular images. Considering each stereo pair in isolation leads to inconsistency on image sequences. By incorporating a motion-tracking algorithm this problem is significantly reduced. In this paper we describe a novel approach to stereo matching on image sequences for the purpose of generating multiple virtual camera views. Results of extensive tests on stereo image sequences, will be documented indicating that this approach is promising both in terms of the speed of execution and the quality of the results produced.
Design principles of a soft-switching cell usable in bridge DC-DC and DC-AC converters (2003)

This paper proposes a soft-switching cell, based on the concept of input voltage cancellation or switching input supply, performed with a resonant commutated pole at the input of any bridge converter. The proposed auxiliary switching cell permits soft switching in all bridge topologies (half bridge, full bridge and 3-phase), in any load conditions, even with bi-directional input current.
The Polytropic Analysis of Centrifugal Compressors (1962)

The real-gas equations of polytropic analysis are derived in terms of compressibility functions X and Y which supplement the familiar compressibility factor, Z. A polytropic head factor, f, is introduced to adjust test results for deviations from perfect-gas behavior. Functions X and Y are generalized and plotted for gases in corresponding states.
Gamma-carboxylated isoforms of recombinant human protein S with different biologic properties (1990)

Human protein S (HPS), a regulator of hemostasis, is a vitamin K-dependent plasma protein with potential clinical utility. We have obtained high-level expression of the cDNA for HPS in two mammalian cell lines. Both cell lines secreted single chain recombinant HPS (rHPS) in serum-free medium as determined by Western blot analysis. The ability of the rHPS from both cell lines to act as a cofactor for human protein C (HPC) was determined; the rHPS secreted from the human 293 cell line had an activity six times that of the rHPS from the AV12-664 Syrian hamster cell line. Furthermore, the relative specific cofactor activity of rHPS from the 293 cell line was actually 2.5-fold higher than that of single-chain human plasma-derived HPS. Essentially all of the rHPS secreted from the 293 cell line exhibited a calcium-dependent elution profile on anion exchange chromatography, whereas only 25% to 35% of the hamster cell-derived rHPS exhibited this profile. However, the calcium-eluted rHPS from the AV12 cell line had a high specific cofactor activity, equivalent to that of the 293-derived rHPS. A NaCl-elutable rHPS fraction (calcium nondependent) was isolated from the recombinant AV12-664 cell line, further purified, and found to have reduced activity, only 40% that of the calcium-dependent rHPS. The only observable difference in the calcium-dependent and nondependent rHPS molecules was in the content of gamma-carboxyglutamic acid (Gla); the calcium-dependent material contained approximately 10 mol Gla/mol protein whereas the calcium-nondependent material contained only approximately 8 mol Gla/mol of protein. In addition, the calcium-nondependent rHPS had reduced ability to interact with phospholipid vesicles as evidenced by an eightfold increase in the apparent kd. Our data demonstrate the isolation of rHPS with high specific activity, and show that a reduction in as few as two Gla residues dramatically decreases its functional cofactor activity for HPC, due to a reduction in ability to interact with the phospholipid bilayer.
Design and Implementation of Noncontact Measurement Device for Irregular Dental Osseointegration Detection (2011)

The dental implantation has been a popular treatment for edentulous and partially dentate patients. To assess osseointegration and discriminate bone defects effectively is demanding for obtaining successful dental implantation. This study aims at developing noncontact a detection technique to measure the severity as well as to locate the orientation of imperfection around bone-implant interface based on resonance frequency analysis (RFA). To justify the effectiveness, both in vitro (artificial bone defects) and in vivo (animal tests) models were performed. A prototype design of an integrated excitation and detection transducer was proposed.

Destiny and Freedom in the Bahá’í Writings (2010)

The 28th Hasan M. Balyuzi Memorial Lecture To know the boundaries of one’s destiny and freedom and, especially, to know how the latter can be best used are two very common aspirations among human beings. This paper will comment upon a number of relevant, mainly officially translated, Writings, some untranslated Tablets, as well as a few talks by ‘Abdu’l-Bahá and interpretations by Shoghi effendi. human destiny is a mystery and only the true seeker can obtain an insight into it. Life itself will assist him in this endeavor. Human beings are free, and yet their lives are regulated by the decrees of God, both irrevocable and revocable decrees. a man best uses his freedom, if he understands God’s will and makes a disciplined effort to fulfill it in his daily life, with radiant acquiescence.
Higher order blind source separation using the cyclostationarity property of the signals (2002)

Over the last decade, a great number of higher order (HO) blind source separation methods have been developed, aiming at separating several statistically independent sources without any a priori information about the latter. A performance analysis of some of these methods has shown that the latter perform very well in a great number of situations encountered in radiocommunication contexts but fail in separating several Gaussian sources. Besides, their performance degrades in the presence of background noise which is either spatially correlated or non-Gaussian, a situation encountered in the HF bandwidth. In this context, the purpose of this paper is to present and to analyse the performance of a new family of HO blind source separation methods exploiting the potential cyclostationarity of the received sources to overcome most of the limitations of the classical HO blind source separation methods while keeping their good properties.

Tracheal transplantation (2012)

This will enable wider application of tracheal allotransplantation for patients in need of complex reconstructive surgery for airway defects that are not amenable to standard methods of repair. Ongoing research suggests that tracheal allotransplantation may become available as a new treatment modality. Additional data are needed to define optimal withdrawal of immunosuppressants without loss of airway lumen.
A novel CoSi/sub 2/ thin film process with improved thickness scalability and thermal stability (2002)

Novel silicidation processes have been developed to improve the thermal stability of thin CoSi/sub 2/ films (250 /spl Aring/ to 1200 /spl Aring/) by the following silicidation schemes: (1) using as-deposited amorphous Si gate, (2) applying light nitridation to the silicon surface before depositing metals, and (3) using a Co/Ti bilayer technique for growing epitaxial CoSi/sub 2/ layer. Individually, each of the three schemes provides improved thermal stability, while a highly stable CoSi/sub 2/ film on both polysilicon and Si substrate can be obtained by combining these three schemes, in which the CoSi/sub 2/Si structure is stable up to 1100/spl deg/C/30 s and the CoSi/sub 2/polysilicon structure is stable up to 1000/spl deg/C/30 s.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Chemical vapor infiltration (1992)

Continuous filament ceramic composites are enabling new, high temperature structural applications. Chemical vapor infiltration methods for producing these composites are being studied, with the complexity of filament weaves and deposition chemistry merged with standard heat and mass transport relationships. Silicon carbide-based materials are, by far, the most advanced, and are already being used in aerospace applications. This paper will address the state-of-the-art of the technology and outline current issues.
Mesoporous carbons with graphitic structures fabricated by using porous silica materials as templates and iron-impregnated polypyrrole as precursor (2005)

Templated mesoporous carbons containing graphitic structures and a well-developed porosity were synthesised by using mesoporous silica materials (i.e. SBA-15 and silica xerogel) as templates and polypyrrole as carbon precursor. The polypyrrole was synthesised by in situ polymerization of pyrrole which was infiltrated into the silica pores containing FeCl3. The carbonization of polypyrrole in presence of iron allows carbon structures with some degree of graphitic order to be formed. The samples were characterised by XRD, nitrogen sorption, TEM, Raman and elemental analysis. The results show that the templated carbons have BET surface areas >1000 m2 g−1 and a porosity built up by two pore systems with sizes centred at ∼3–4 nm and at 10–14 nm. In addition, they have a good electrical conductivity due to the presence of graphitic structures in the carbon framework.

How bacterial pathogens colonize their hosts and invade deeper tissues (2015)

Bacterial pathogens have evolved a wide range of strategies to colonize and invade human organs, despite the presence of multiple host defense mechanisms. In this review, we will describe how pathogenic bacteria can adhere and multiply at the surface of host cells, how some bacteria can enter and proliferate inside these cells, and finally how pathogens may cross epithelial or endothelial host barriers and get access to internal tissues, leading to severe diseases in humans.
Comparison of Uniaxial Strain and Hydrostatic Stress Pore-Volume Compressibilities in the Nugget Sandstone (1983)

This paper presents a comparison of rock compressibilities determined under two different stress states. One stress state was the traditional though unrealistic hydrostatic stress method; the other was the more realistic though more complicated uniaxial strain (triaxial stress) with pore pressure method. Compressibilities were determined by both stress methods on Nugget sandstone core plugs from the Rocky Mountain Overthrust Belt. The resulting relationship between the two types of compressibilities did not match with previously published predictions.The uniaxial strain pore volume compressibilities averaged about one-third of the corresponding hydrostatic stress pore volume compressibilities. This was a greater difference than predicted using standard practices. Also, the uniaxial strain data varied only slightly between samples, while the hydrostatic stress data exhibited a greater range of values. From the uniaxial strain measurements, bulk volume compressibility of the Nugget sandstone is constant over the porosity and pressure range of the reservoir. Pore volume compressibility can therefore be easily determined from the porosity and the bulk volume compressibility.
Subwavelength ripple formation on the surfaces of compound semiconductors irradiated with femtosecond laser pulses (2003)

High-spatial-frequency periodic structures on the surfaces of InP, GaP, and GaAs have been observed after multiple-pulse femtosecond laser irradiation at wavelengths in the transparency regions of the respective solids. The periods of the structures are substantially shorter than the wavelengths of the incident laser fields in the bulk materials. In contrast, high-frequency structures were not observed for laser photon energies above the band gaps of the target materials.
A Method for Learner Grouping Based on Personality Clustering (2006)

Grouping learners according to their features in the Web-based learning environment is a key to build personalization learning system. This paper proposes a new method for learner grouping based on personality clustering. We first build a learner model including a personality model and a behavior mode, which is the basis of learner grouping. Furthermore, the feasibility of K-means algorithm being used in learner grouping is discussed. In addition, the process and result of learner grouping based on personality clustering is investigated. The result of experiment indicated that this method is feasible and efficient
The structure, magnetism, and electrical-transport properties of the Heusler alloys Co2Cr1−xFexAl(x=0.2–0.6) (2005)

We synthesize the polycrystalline Heusler compounds Co2Cr1−xFexAl(x=0.2−0.6). The x-ray diffraction patterns show A2 structure rather than L21 structure. The magnetic moment and the Curie temperature increase with increasing x. The electrical resistivity characterizes the Co2Cr1−xFexAl compounds to be not typical metals and the temperature dependence of the resistivity changes from metallic to semiconductinglike behavior with increasing Cr concentrations. We attribute the fact, which we observe for most of the compounds smaller magnetic moments than the theoretical values and the low magnetoresistance in these alloys, to the considerably high level of Co-(Cr, Fe)-type disorder.
Specification and synthesis of hardware checkpointing and rollback mechanisms (2012)

The increasing pressure to make hardware resilient to runtime failures has prompted development of design techniques for specific classes of systems, e.g. processors and routers. However, these techniques come at increased design and verification costs, thus limiting their broader application. In this work we describe a methodology for general RTL designs based on the widely usable checkpointing and rollback resiliency mechanism. We take a modeling and language approach that provides an appropriate set of abstractions for the resiliency logic. This cleanly separates the main design behavior from the resiliency behavior, leading to ease of design. Further, as the language abstractions can be automatically synthesized into resiliency logic, our methodology can merge with existing design flows. The concerns of verifying this additional resiliency logic can be addressed by synthesizing behavioral assertions capturing correct behavior. We demonstrate the use of this methodology on four examples, with synthesis for performance and area to estimate the overhead of the additional synthesis logic.
