Structure and properties of graded cemented carbides sinter-bonded onto steel (1998)

From adjustment gears for sprinkler systems to surgical scissors, from latchbolts to parking gears, the winners of the Metal Powder Industries Federation's (MPIF) 1998 part-of-the-year design competition represent further market breakthroughs for powder metallurgy (PM). The winning parts show successful conversions from malleable iron, plastic injection moulding, investment casting, forging, die casting and machining, with significant cost savings and enhanced design complexity.
Using the SSAV model to evaluate Business Intelligence Software (2012)

Choosing the right Business Intelligence (BI) software is critical to increasing productivity and effectiveness in organizations today. At the same time it is a very elaborating and complex process to choose the right software due to the fact that a large number of BI products exist on the market, which are quite different and updated frequently. The objective of this study is to develop and test a model for the evaluation of BI Software. The findings of the study revealed that it is difficult to declare what is the most competitive BI software as what is good for one user might not be good for another depending on their different business needs. Having said that the study initiated a new classification of BI Software vendors depending on the degree to which they comply with the functions in the Competitive Intelligence (CI) cycle. The software tested was divided into five categories: Fully complete, Complete, Semi Complete, Incomplete and Insubstantial. We conclude that the SSAV (Solberg Søilen, Amara, Vriens) Model Together with some proposed non technological variables and a classification developed can be used as a user's selection tool for deciding which BI Software to purchase.

Overlapping Probabilities of Top Ranking Gene Lists, Hypergeometric Distribution, and Stringency of Gene Selection Criterion (2006)

When the same set of genes appear in two top ranking gene lists in two different studies, it is often of interest to estimate the probability for this being a chance event. This overlapping probability is well known to follow the hypergeometric distribution. Usually, the lengths of top-ranking gene lists are assumed to be fixed, by using a pre-set criterion on, e.g., p-value for the t-test. We investigate how overlapping probability changes with the gene selection criterion, or simply, with the length of the top-ranking gene lists. It is concluded that overlapping probability is indeed a function of the gene list length, and its statistical significance should be quoted in the context of gene selection criterion.
BEECP: Biogeography optimization-based energy efficient clustering protocol for HWSNs (2016)

Energy saving is the prominent requirement of wireless sensor networks implemented in harsh environments. This paper examines the diminution of energy utilization of wireless sensor networks using efficient cluster head election with a novel clustering protocol inspired by biogeography-based optimization. Simulation results show that the proposed method prolongs the overall network lifetime and stability period as compared to other evolutionary-based clustering protocols like stable election protocol (SEP), evolutionary routing protocol (ERP), and intelligent hierarchical clustering routing (IHCR).
Ionization relaxation in a plasma produced by a pulsed inert-gas discharge (1983)

A model is developed for the initial stage of ionization relaxation in a pulsed inert-gas discharge plasma at moderate pressures for E/n/sub 1/ values corresponding to ionization levels n/sup 0//sub e//n/sup 0//sub 1/>>10/sup -4/. It is shown that the electron density increases explosively in time due to accumulation of atoms in the lowest excited states. An approximate analytic solution is found for describing the behavior of the time and spatial increase in n/sub e/ as a function of the specific conditions. The proposed model is verified experimentally.
Loss of the insular ribbon: another early CT sign of acute middle cerebral artery infarction. (1990)

Although computed tomography (CT) remains the most frequently used imaging examination in acute cerebral infarction, its sensitivity for early detection of strokes remains limited. In middle cerebral artery (MCA) strokes less than 6 hours old, loss of definition of the gray-white interface in the lateral margins of the insula ("insular ribbon") was observed. The acute and subacute CT findings in 11 retrospective and 16 prospective patients are presented. Loss of the insular ribbon was detected in 12 of the prospective cases and in all 11 retrospective cases. The insular ribbon is supplied by the insular segment of the MCA and its claustral branches. With cessation of MCA flow, the insular ribbon becomes the region most distal from the anterior and posterior cerebral collateral circulations. Consequently, the insular ribbon effectively becomes a watershed arterial zone. Loss of the insular ribbon is thus a reflection of acute edema due to infarction. Loss of the insular ribbon appears to be another frequent and reliable finding in acute MCA stroke.
Electro Magnetic and Heat Conductive FE Analysis on High Frequency Tube Welding Process (2007)

A three-dimensional high frequency tube welding heat model has been developed by using electro magnetic and heat conduction finite element methods. Eddy current density distribution at a static state is calculated by means of a frequency response analytic law. Heat transfer in the tube circumferential and longitudinal direction is calculated with heating and cooling. This model is verified by experiments with laboratory-scale electric resistance welding mill. The analysis has good agreement with the actual measurement. This model can satisfactorily simulate the eddy current density distribution and the temperature distribution in the high frequency tube welding. The influences of welding frequency, welding speed, and magnetic permeability of impeder on a temperature distribution of a tube are quantitatively clarified.
Alterations in cardiovascular function during neurolept anesthesia for surgery on the coronary vessels. (1978)

Induction of anesthesia for aortocoronary bypass surgery was accomplished by the administration of droperidol, morphine, oxygen and nitrous oxide-oxygen in 20 patients. They ranged from 40 to 69 years of age. Premedication consisted of diphenhydramine and morphine. Cardiovascular stability was the most important aspect of the technique. Heart rate changes were insignificant. Cardiac index increased substantially after droperiodol and remained unchanged after morphine. It stayed around control levels for the rest of the induction. A substantial decrease was observed while using mechanical ventilation. Mean arterial pressure dropped significantly after droperidol and again after morphine, then rose about 17% after oxygen to near control levels, where it stayed thereafter. Peripheral vascular resistance dropped substantially after droperidol. A significant increase occurred after oxygen, reaching almost control levels at this point. Mechanical ventilation caused a significant increase, similar to the decrease in the cardiac index. Decreased oxygen availability was compensated for by decreased oxygen consumption. Induction of neurolept anesthesia in the manner described appears to be void of the undesirable effects of either large doses of morphine, or nitrous oxide-oxygen following such morphine doses. Amnesia was complete in every patient.
Polarization-induced astigmatism caused by topographic masks (2007)

With the continuous shrink of feature sizes the pitch of the mask comes closer to the wave length of light. It has been recognized that in this case polarization effects of the mask become much more pronounced and deviations in the diffraction efficiencies from the well-known Kirchhoff approach can no longer be neglected. It is not only the diffraction efficiencies that become polarization-dependent, also the phases of the diffracted orders tend to deviate from Kirchhoff theory when calculated rigorously. This also happens for large structures, where these phase deviations can mimic polarization dependent wave front aberrations, which in the case of polarized illumination can lead to non-negligible focus shifts that depend on the orientation and the features size themselves. This orientation dependence results in a polarization induced astigmatism offset, which can be of the same order of magnitude or even larger as polarization effects stemming from the lens itself. Hence, for correctly predicting polarization induced astigmatism offsets, one has to both consider lens and mask effects at the same time. In this paper we present a comprehensive study of polarized induced phase effects of topographic masks and develop a simple theoretical model that accurately describes the observed effects.
Automatic shadow enhancement in intra vascular ultrasound (IVUS) images (2014)

The goal of image enhancement is improving the interpretability or perception of information in images for human viewers. This paper describes, an automated algorithm for shadow region detection and enhancement in intravascular ultrasound (IVUS) images using an adaptive threshold method for threshold selection, contour approach for border detection and image enhancement algorithm including histogram analysis for the shadow regions improvement. As shadow appears behind the calcification plaque, it makes it difficult or impossible for the dark region to process automatically around these regions. The acoustic shadow usually follows the hard plaque in IVUS images and it can distinguish calcification regions from other bright regions. Therefore we propose to use Otsu Threshold for calcification plaque segmentation and the Active contours without edge method for shadow region separation of the image and histogram matching for shadow enhancing. Results show that the proposed method efficiently detected shadow regions even in complicated images.
Simple Semi-Supervised Training of Part-Of-Speech Taggers (2010)

Most attempts to train part-of-speech taggers on a mixture of labeled and unlabeled data have failed. In this work stacked learning is used to reduce tagging to a classification task. This simplifies semi-supervised training considerably. Our prefered semi-supervised method combines tri-training (Li and Zhou, 2005) and disagreement-based co-training. On the Wall Street Journal, we obtain an error reduction of 4.2% with SVMTool (Gimenez and Marquez, 2004).
Uniqueness of blur measure (2005)

After discussing usual approaches to measuring blur, we show theoretically that there is essentially a unique way to quantify blur by a single number and we confirm the usefulness of that measure by some experiment on a natural image.
Beta-Zirconium Oxide Monophosphate:  Structural Keys for an Ultralow Expansion Material (2003)

Rietveld analyses performed on high-temperature X-ray (HTXRD) and neutron (HTND) powder patterns of β-(Zr2O)(PO4)2 have allowed us to follow accurately the thermal variations of the cell parameters and to explain its strong dilatometric anisotropy in terms of structural distortions. It appeared that the anomaly resulted from two simultaneous mechanical effects: libration movements of the bridging oxygen atoms related to a rocking of the ZrO7 and PO4 polyhedra and a rotation effect resulting from electrostatic repulsions between ZrIV cations of neighbor polyhedra. Both effects lead to a strong shrinkage of the b parameter and contribute to the ultralow overall expansion that has made β-(Zr2O)(PO4)2 famous as a thermal-shock resistant material.
A novel channel estimation algorithm for sounding reference signal in LTE uplink transmission (2009)

A novel channel estimation algorithm for sounding reference signal in DFT-Spread OFDM (DFT-S OFDM) system is proposed, which can estimate the channel response with high efficiency. According to the MSE metric between the estimated channel response and the real one, the simulation result shows that the intra-cell interference is neglectable while the effect of the inter-cell interference is so serious that certain IC (Interference Cancellation) techniques must be considered in the system design.
View and texture-independent facial expression recognition in videos using dynamic programming (2005)

In this paper, we address the recognition of facial expressions in continuous videos. We introduce a fast and texture-independent approach that exploits facial action parameters estimated by an appearance-based 3D tracker. We represent the learned facial actions associated with different facial expressions by time series. We adopt a dynamic time warping technique for recognizing the facial expressions using similarity measures between the learned time series and the tracked ones. The developed approach can be used online and can deal with non-frontal face images since it is view-independent. Preliminary experiments demonstrated the effectiveness of the developed method.
[Studies on the phenotype deviation of the single-cell subclones of human stomach carcinoma MGC-803 cell line]. (1996)

The diversity of phenotypes of tumor cells is the main reason for the differences of drug-sensitivity, immunology, metastatic properties and cellular growth rate, and thus raises difficulties in tumor diagnosis and therapy. In order to investigate the mechanisms involved in the expression, correlation, development and regulation of the diversed malignant phenotypes, cell models from single-cell subclones of human stomach carcinoma cell line MGC-803 were studied. According to the growing time needed for the process of separation of each single-cell subclone, they were categoried into 3 groups as fast growing, moderatly and slowly growing subclones and named. From each group, representative subclones were selected--M17 fast. M6 moderate and M3 slow, for further comparative studies. Foci frequency in soft agar was very high with M17, very low with M3, and M6, the middle. The difference in the major transformed phenotype among the 3 subclones were statistically significant. There were differences in the function of gap junctional intercellular communication as detected by scrape-loading and dye transfer method. M17 negative, while M6 and M3 were positive with dye transfer. Immunocytochemical staining of cytoskeleton elements showed heavy disruption of microtubule and microfilament networks and appearance of F-actin aggregates in M17 cells. On the other hand, M3 showed less disruptive changes and more normal appearance of microtubules and microfilament organization. Immunofluorescent staining showed marked differences in gene expression of c-myc, c-Ha-ras and c-met between M17 and M3. M17 expressed intense fluorescence of the 3 onco-proteins while M3 was negative with c-myc and c-Ha-ras, only weak c-met fluorescence in the cytoplasm.

The assortments of their synthetic methods are then summarized, including insights on their advantages and limitations, alongside some recommendations on suitable characterization techniques. We also discuss in detail the utilization of these ultrathin 2D nanomaterials for wide ranges of potential applications among the electronics/optoelectronics, electrocatalysis, batteries, supercapacitors, solar cells, photocatalysis, and sensing platforms. Finally, the challenges and outlooks in this promising field are featured on the basis of its current development.
TREC-3 Ad Hoc Retrieval and Routing Experiments using the WIN System. (1994)

Introduction The WIN retrieval engine is West&apos;s implementation of the inference network retrieval model [Tur90]. The inference net model ranks documents based on the combination of different evidence, e.g., text representations, such as words, phrases, or paragraphs, in a consistent probabilistic framework [TC91]. WIN is based on the same retrieval model as the INQUERY system that has been used in previous TREC competitions [BCC93, Cro93, CCB94]. The two retrieval engines have common roots but have evolved separately -- WIN has focused on the retrieval of legal materials from large (?50 gigabyte) collections in a commercial online environment that supports both Boolean and natural language retrieval [Tur94]. For TREC-3 we decided to run an essentially unmodified version of WIN to see how well a state-of-the-art commercial system compares to state-of-the-art research systems. Some modifications to WIN were required to handle the TREC topics, which bear little resem

Deleted in Colorectal Carcinoma and Differentially Expressed Integrins Mediate the Directional Migration of Neural Precursors in the Rostral Migratory Stream (2002)

Precursors of the olfactory interneurons migrate from the subventricular zone via the rostral migratory stream (RMS). To investigate the molecular mechanisms by which RMS cells migrate, we used a slice preparation, which allows the migrating cells to be imaged at very high temporal and spatial resolution in the presence of added inhibitors. Using immunohistochemistry, we first determined that the α1-, β8-, and β1-integrin subunits and the α5- and γ1-laminin subunits are expressed during embryonic day 16 to the early postnatal stage. During early postnatal days, αv- and β6-integrins appeared, and their expression persisted throughout adulthood. The migrating cells also expressed the netrin receptors neogenin and Deleted in Colorectal Carcinoma (DCC). Netrin-1 is expressed in olfactory mitral cells. Anti-integrin antibodies inhibited the production of protrusions as well as cellular translocation. In contrast, anti-DCC antibodies primarily altered the direction of the protrusions; consequently, the migration was no longer unidirectional, and the speed was reduced. Thus, the interaction of DCC, possibly through an interaction with netrin-1, contributes to the direction of migration by regulating the formation of directed protrusions. In contrast, the integrins function in production of protrusions and cellular translocation, with different integrins participating at different developmental stages.
An Investigation of Scheduling and Packet Reordering Algorithms for Bandwidth Aggregation in Heterogeneous Wireless Networks (2013)

Heterogeneous Wireless Network (HWN) is the next generation wireless communication system’s platform where Internet services will be offered and delivered through multiple technologies like WiFi,WiMAX, GSM etc. There are some Internet applications that require high bandwidth and therefore, the bandwidth of an individual interface need to be aggregated to form a high speedy logical link. In this regard,some critical issues like packet loss, packet reordering and delay need to be addressed efficiently. This paper aims to investigate the common scheduling algorithms both adaptive and non-adaptive solutions that have been using in networking and communication field. Packet reordering is common in heterogeneous wireless network that has been evaluated briefly in reorder metrics analysis and reorder delay analysis sections. The challenges of packet reordering are also addressed in this paper. This paper gives a state-of-the-art knowledge of bandwidth aggregation and packet reordering in HWN and it is expected that this investigation will be a milestone for further research.

Holey graphene hydrogel with in-plane pores for high-performance capacitive desalination (2016)

Capacitive deionization is an attractive approach to water desalination and treatment. To achieve efficient capacitative desalination, rationally designed electrodes with high specific capacitances, conductivities, and stabilities are necessary. Here we report the construction of a three-dimensional (3D) holey graphene hydrogel (HGH). This material contains abundant in-plane pores, offering efficient ion transport pathways. Furthermore, it forms a highly interconnected network of graphene sheets, providing efficient electron transport pathways, and its 3D hierarchical porous structure can provide a large specific surface area for the adsorption and storage of ions. Consequently, HGH serves as a binder-free electrode material with excellent electrical conductivity. Cyclic voltammetry (CV) measurements indicate that the optimized HGH can achieve specific capacitances of 358.4 F·g−1 in 6 M KOH solution and 148 F·g−1 in 0.5 M NaCl solution. Because of these high capacitances, HGH has a desalination capacity as high as 26.8 mg·g−1 (applied potential: 1.2 V; initial NaCl concentration: ~5,000 mg·L−1).
