The authors describe a highly sensitive and practical in situ hybridization method using an oligonucleotide probe for EBER1 RNA for the detection of Epstein-Barr virus (EBV) in formalin-fixed, paraffin-embedded tissue sections. Paraffin-embedded tissues from 793 cases of normal and neoplastic tissues were studied. Nuclear staining for EBV RNA was uniformly present in all or virtually all neoplastic cells in a variety of known EBV-positive tumors. We also demonstrate rare EBV-infected cells in no ...
Recent anatomical tracing studies have yielded substantial amounts of data on the areal connectivity underlying distributed processing in cortex, yet the fundamental principles that govern the large-scale organization of cortex remain unknown. Here we show that functional similarity between areas as defined by the pattern of shared inputs or outputs is a key to understanding the areal network of cortex. In particular, we report a systematic relation in the monkey, human, and mouse cortex between ...
Neurophysiological and behavioral studies have shown that perception and memory share neural substrates and functional properties. But are perception and the active working memory of a stimulus one and the same? To address this question in the spatial domain, we compared the percept and the working memory of the position of a target stimulus embedded within a surround of moving dots. Motion in a particular direction after the target's offset biased the memory of target location in the same direc ...
Single layers of WS2 nanoplates are uniformly embedded in nitrogen-doped carbon nanofibers (WS2@NCNFs) via a facile electrospinning method. Crystallization of the single-layered WS2 nanoplates and in situ nitrogen doping into the carbon nanofibers were simultaneously accomplished during a two-step heat treatment. The distinctive structure of the WS2@NCNFs enables outstanding electrochemical performances. ...
Four isomers are currently known for the trioxygenated fullerene derivative C(60)(O)(3), three regioisomers with all of the oxygen addends as epoxy groups and the unstable ozonide isomer with a 1,2,3-trioxlane ring. Here we report the synthesis of an open-cage isomer for C(60)(O)(3) with a ketolactone moiety embedded into the fullerene skeleton through a three-step procedure mediated by fullerene peroxide chemistry. Two fullerene skeleton carbon-carbon bonds are cleaved in the process. The open- ...
Hematoxylin bodies are considered to be the only pathognomonic feature of systemic lupus erythematosus. In this paper, the ultrastructure of hematoxylin bodies is described in a patient with active lupus glomerulonephritis. For identification of hematoxylin bodies, electron micrographs at low magnification were compared with hematoxylin-eosin-stained, Epon-embedded sections from the same block. One electron micrograph at low magnification displayed a whole glomerulus. The bodies were then studie ...
To acquire continuous observation results is an essential demand to environmental monitoring. Wireless sensor networks (WSNs), composed of many tiny sensing equipment, give a good solution to collect continuously temporal and spatial data. Due to the limitation of WSNs, such as volume of wireless sensors, cost, energy, processing capability, and transmission distance, we need a solution in charge of collecting sensed data and transmitting it to the backend server. This solution has to handle all ...

This paper presents an comparison on interactivity of three Linux schedulers: O (1), CFS and MIOS [1], in an embedded system. We have ported the O (1) and MIOS into Linux 2.6.32, and done the test in this framework. Different experiments in both high workload and low workload are done in a 0.16 millisecond accuracy. The result shows that a) CFS is not the best in interactivity comparing with O(1) and MIOS; b) CFS is more fair even in high workload; c) O(1) and MIOS differ very slightly on intera ...
This paper describes the fabrication of a novel stretchable fingernail sensor prototype, mounted on the fingernail for detecting fingertip touch force direction. Fingernail sensors are optical reflectance photoplethysmograph sensors that detect the change in blood perfusion in the nail bed, as the finger pad touches a planar surface with various forces. The original fingernail sensor was rigidly attached to the human fingernail and accordingly needed to be customized to the geometry of the finge ...
Blowups are an important technique in algebraic geometry that permit the smoothing of singular algebraic varieties. It is a challenge to visualize this process even in the case of blowups of points X in the affine plane AA<sup>2</sup><sub>IR</sub>. First results were obtained by Brodmann with the aid of the so-called toroidal blowup, a compact embedding of the blowup into affine 3-space. In fact, Brodmann provides a rational parametrization of the toroidal blowup, but its ...
BACKGROUND The prognostic significance of tumor DNA ploidy in patients with cancer of the pancreas has not been defined because conflicting results have been reported. METHODS DNA content was measured in 56 ductal adenocarcinomas of the pancreas. DNA ploidy status was evaluated by flow cytometry in nuclei isolated from paraffin-embedded tumor tissues. RESULTS An abnormal DNA stemline was observed in 27 (48%) patients. The percentage of aneuploid tumors was significantly increased in tumors c ...
The HC2D barcode is a highest capacity of 2D barcode while it occupies a small area. The size of the HC2D barcode is suitable for displaying on print media such as paper and poster. But, for reading the HC2D barcode, the bit representation of the barcode is obtained by scanning the image of the barcode with scanner machine only. This paper shows the implementations of image reorganization of HC2D barcodes in mobile phones with android operating system. The mobile phone system used here consists ...
The load/store pipe in an embedded processor is clocked at 2/spl times/ the processor clock frequency. It sustains two load or store operations per core clock cycle with zero load-to-use issue latency. The design is implemented in 0.13/spl mu/m 7M CMOS process and dissipates between 650 and 1090mW for core clock frequencies between 600MHz and 1GHz. ...
This paper proposes a fragile image watermarking scheme with recover ability based on local binary pattern (LBP). The local binary pattern operator is mostly used to extract localized spatial features for texture analysis, image classification, and pattern recognition. According to spatial relations of a natural image, a local binary pattern can be utilized to represent the localized relations of a pixel with its neighborhood. Each pixel measured by the LBP operator can be obtained its own local ...
An old problem of P. Levy is to characterize those Banach spaces which embed isometrically in Lp. We show a new criterion in terms of the second derivative of the norm. As a consequence we show that, if M is a twice differentiable Orlicz function with M (0) = M (0) = 0, then the n-dimensional Orlicz space l M , n ≥ 3 does not embed isometrically in Lp with 0 < p ≤ 2. These results generalize and clear up the recent solution to the 1938 Schoenberg’s problem on positive definite functions ...
The interaction between the prosthetic group 6,7-dimethyl-8-(1'-D-ribityl)lumazine and the lumazine apoproteins from two marine bioluminescent bacteria, one from a relatively thermophilic species, Photobacterium leiognathi, and the other from a psychrophilic species, Photobacterium phosphoreum, was studied by 13C and 15N NMR using various selectively enriched derivatives. It is shown that the electron distribution in the protein-bound 6,7-dimethyl-8-ribityllumazine differs from that of free 6,7- ...
In this note we shall prove that every locally compact group can be embedded as a closed subgroup in a unimodular group. If the original group is locally Euclidean, the enlarged group will be also, hence the fifth problem of Hilbert is reduced to the unimodular case. We shall use certain results concerning Haar measure whose proof may be found in A. Weil, U integration dans les groupes topologiques et ses applications, Paris, Hermann, 1938, Chap. II, which we shall refer to as AW. Let ƒ stand f ...
The prediction of RNA structure is a major field of bioinformatics research. A framework for modeling RNA 3D structures based on sequence-to-structure alignment via genetic algorithm (RAGA) has been designed in a previous work. Due to performance and robustness problems with the RAGA algorithm it has to be exchanged with a newly developed method: Lagrangian Relaxed RNA structure alignment (LR-RSA). This thesis describes the necessary modifications which had to be applied to the framework to embe ...

Reversible data hiding (RDH) is a special class of steganography that can not only embed secret data into images, but also can restore the original images after secret data are extracted. Prediction-based techniques constitute an important class of reversible data hiding methods. However, most prediction-based RDH rely on the use of a single predictor to compute predictions that are used for data embedding. This may restrict the embedding capacity and image quality. The objective of this paper i ...
It is reported that the ductility and strength of a metal matrix composite could be concurrently improved if the reinforcing particles were of the size of nanometers and distributed uniformly. In this paper, we revealed that gas atomization solidification could effectively disperse TiB2 nanoparticles in the Al alloy matrix due to its fast cooling rate and the coherent orientation relationship between TiB2 particles and α-Al. Besides, nano-TiB2 led to refined equiaxed grain structures. Furthermo ...
Everyone has their own unique version of the visual world and there has been growing interest in understanding the way that personality shapes one's perception. Here, we investigated meaningful visual experiences in relation to the personality dimension of schizotypy. In a novel approach to this issue, a non-clinical sample of subjects (total n = 197) were presented with calibrated images of scenes, cartoons and faces of varying visibility embedded in noise; the spatial properties of the images ...
In many biological systems, variability of the components can be expected to outrank statistical fluctuations in the shaping of self-organized patterns. In pioneering work in the late 1990s, it was hypothesized that a drift of cellular parameters (along a 'developmental path'), together with differences in cell properties ('desynchronization' of cells on the developmental path) can establish self-organized spatio-temporal patterns (in their example, spiral waves of cAMP in a colony of Dictyostel ...
Recent results suggest that observers can learn, unsupervised, the co-occurrence of independent shape features in viewed patterns (e.g., Fiser & Aslin, 2001). A critical question with regard to these findings is whether learning is driven by a structural, rule-based encoding of spatial relations between distinct features or by a pictorial, template-like encoding, in which spatial configurations of features are embedded in a 'holistic' fashion. In two experiments, we test whether observers can le ...
Emerging single cell technologies have provided rich, high dimensional datasets. Analysis of single cell data has shed light on various different cellular processes. [1] These data have proved to be particularly useful in many important medical applications. One of the most prominent applications is to detect cancer tumors. These datasets from single-cell mass cytometry often come in the form of large matrices, where each column represents measurements of some parameter of interest, such as the ...
This article presents a summary and critical review of what is known about the 'grouped retina', a peculiar type of retinal organization in fish in which groups of photoreceptor cell inner and outer segments are arranged in spatially separated bundles. In most but not all cases, these bundles are embedded in light-reflective cups that are formed by the retinal pigment epithelial cells. These cups constitute a specialized type of retinal tapetum (i.e., they are biological 'mirrors' that cause eye ...
A laboratory tank was used to study entrapment of water in coarse sand lenses above the water table and of air in coarse sand lenses below the water table. Monitoring of these experiments involved a combination of visual inspection, measurement of moisture content, and measurement of air/water pressure. The medium consisted of coarse sand lenses with various degrees of vertical connectivity embedded within a fine sand matrix. Experiments were performed under conditions of both drainage (from a f ...
Three-dimensional graphene-supported TiO2 nanorod nanocomposites (3D GS-TNR) are prepared using graphene oxide hydrogel as a restricted-area nanoreactor in the hydrothermal process, in which well-distributed TiO2 nanorods with a width of approximately 5 nm and length of 30 nm are conformally embedded in the 3D interconnected graphene network. The 3D graphene oxide not only works as a restricted-area nanoreactor to constrain the size, distribution and morphology of the TiO2; it also work as a hig ...
For the purpose of investigating a topographical correlation between antigen molecules and protein A-gold(PAG) particles which localized as an immunocytochemical probe, the simplest model on a localization pattern of antigen molecules, which were arranged two-dimensionally on a plane surface of the resin, was used. Ultrathin sections of a G-actin layer, which was adsorbed on epoxy resin and was re-embedded subsequently in JB-4 resin, was stained indirectly with rabbit anti-actin antibody and sub ...
The ferroelectric domain structures in 1-3 type bulk magnetoelectric composites were studied using the phase-field method. The ferroelectric polarization distributions in triangle, square, circle, and other polygonsshaped rods embedded in a ferromagnetic matrix were obtained. The influences of ferroelectric particle size and symmetry and the surrounding magnetic phase medium on the stability of double vortex structures are discussed. ...
Metal organic frameworks (MOFs) containing metal nanoclusters (NCs) display great potentials, but the fabrication faces challenges because of the serious agglomeration of NCs during the MOF growth. We report a crystalline ion triggered growth strategy for embedding AuNCs in ZIF-8. As control, when the encapsulation was triggered with other metal ions (e.g. Ca2+, Pb2+, Cd2+, Na+, Fe3+, Cu2+ and Ni2+), the AuNCs failed to be encapsulated. The quantum yields and lifetime of AuNCs were greatly enhan ...
In this paper, a dual-band band stop filter is applied based on a modified stepped impedance hairpin resonator in which, two open stubs are embedded in the structure. There are two transmission zeros in each stop bands. The center frequencies of the stop bands are placed at 2 and 5.92 GHz and their widths are 0.94 and 0.55 GHz, respectively. These stop bands can be adjusted by changing the dimensions of the embedded open stubs. ...
Integration of surface-enhanced Raman scattering (SERS) sensors onto transparent and flexible substrates enables lightweight and deformable SERS sensors which can be wrapped or swabbed on various nonplanar surfaces for the efficient collection and detection of analytes on various surfaces. However, the development of transparent and flexible SERS substrates with high sensitivity is still challenging. Here, we demonstrate a transparent and flexible SERS substrate with high sensitivity based on a ...
We report an ab initio study of the Kondo states formed from a Co adatom on Cu(111) and Cu(100). The model consists of a CoCun cluster ( n = 5-19) embedded in (111) and (100) Cu slabs. An embedding potential derived from density functional theory treats the interaction between the periodic crystal surroundings and the CoCun cluster, while strong electron correlations within CoCun are explicitly accounted for via configuration interaction (CI) methods. Analysis of the embedded CI wave function pr ...

In order to improve the robustness and invisibility of watermarkings embedded into the images, a novel algorithm is presented, which is based on discrete wavelet transformation (DWT). The original watermarking signal is embedded into the lowest frequency sub-band of the wavelet domain. Combined with the technique of encryption, the extracted Krawtchouk moment invariants of the image are used to establish another layer virtual watermarking and a mapping relationship between the two layer watermar ...
There are more than 3000 natural geothermal outcrops in China. The two high temperature geothermal areas in China include the Taiwan geothermal zone and the Himalayan geothermal zone. Low temperature geothermal areas are widely distributed in the vast area of Chinese mainland. The distribution of hot springs, geothermal wells and heat flow are controlled by geological structure. Taking the Ordos Basin and the Sichuang Basin as the centre, the geothermal areas in China can be divided into three s ...
Librarians are increasingly moving out of the library and into the wider university setting as patrons spend more time seeking information online and less time visiting the library. The move to embed librarians in colleges, departments, or customer groups has been going on for some time but has recently received more attention as libraries work to find new ways to reach patrons that no longer need to come to the physical library. Few universities have attempted to embed all their librarians. Thi ...
Recent advances in Xilinx’s FPGA hardware and commercial software design tools, spurred in large part by the DOD’s Joint Tactical Radio System initiative, offer the possibility of incorporating dynamic partial reconfiguration (PR) into highperformance, embedded systems outside of academic research laboratories. PR can provide the flexibility and run-time reconfigurability that no pure hardware or software solution can offer. By multiplexing the hardware resources of a single programmable dev ...

Food related web services, such as recipe websites and food journaling apps, are rapidly gaining popularity. Data from service providers and that generated by users often coexist in these services. Compared to the former, the latter, due to its randomness and lack of organization, is often difficult to incorporate into common service features like recommendation making and associative searching. This work addresses this problem by investigating the effectiveness of multiple text embedding method ...
We describe the application of a polyethylene glycol (PEG) embedding technique to examine the sensory and supporting structures of the inner ear. The chinchilla organ of Corti was exposed by cracking PEG embedded cochleas. A range of PEG molecular weights (2000-8000) were utilized; PEG 2000, with a melting point of 57 degrees C was preferred. After removal of the PEG, the three-dimensional aspects of intracellular structures were observed using scanning electron microscopy. Filamentous elements ...
The goal of unsupervised learning, i.e., clustering, is to determine the intrinsic structure of unlabeled data. Feature selection for clustering improves the performance of grouping by removing irrelevant features. Typical feature selection algorithms select a common feature subset for all the clusters. Consequently, clusters embedded in different feature subspaces are not able to be identified. In this paper, we introduce a probabilistic model based on Gaussian mixture to solve this problem. Pa ...

Rapidly increasing functionality and performance of RF/wireless communication products, along with mandated decreases in size, weight, and cost, have created a critical need to replace discrete, surface-mounted passive circuit components with embedded passives in substrate technologies such as Low-Temperature Cofired Ceramic (LTCC). The design process for embedded passives requires rapid electromagnetic simulation with full mutual coupling among all embedded structures, to allow each design-refi ...
Let G be a connected reductive group. We find a necessary and sufficient condition for a quasiaffine homogeneous space of G/H to be embeddable into an irreducible G-module. If H is reductive we also find a necessary and sufficient condition for a closed embedding of G/H into an irreducible module to exist. These conditions are stated in terms of the group of central automorphisms of G/H . ...
The design of many-core system-on-chips confronts the developer with a more and more challenging task. Modern embedded applications have a continuously increasing requirement for highly parallelized and flexible heterogeneous processor structures. The interconnection problem becomes a crucial design decision with a growing number of parallel cores. Today, these decisions are usually solely based on the designer’s experience. However, this will not be feasible anymore for future many-core syste ...
A redox active polymer, hydroquinone modified chitosan (Q-chitosan) was synthesized and characterized by IR and (1)H NMR spectroscopy. The nanocomposite of Q-chitosan with carbon was prepared and used to construct a stable conductive film on the electrode surface. The SEM studies confirms that the Q-chitosan/C composite covers the electrode surface with polymer embedded 50 nm size carbon particles. The formal redox potential, E(0) of the Q-chitosan/C composite modified electrode is evaluated to ...
This study is part of a project which investigates computational principles which underlie perception and representation of architectural streetscape character. Some of the principles can be associated with fundamental concepts in brain theory and Gestalt psychology. For the experimental analysis streetscapes were represented by sequences of digital images of house facades which were prepared by a team of researchers from architecture. Two methods for non-linear dimensionality reduction, isomap ...
The contribution of this paper is proposing a new entropy extraction mechanism based on sampling phase jitter in ring oscillators to make a high throughput true random number generator in a field programmable gate array (FPGA) practical. Starting from experimental observation and analysis of the entropy source in FPGA, a multi-phase sampling method is exploited to harvest the clock jitter with a maximum entropy and fast sampling speed. This parametrized design is implemented in a Xilinx Artix-7 ...
CdSe/ZnS core-shell quantum dots have been embedded within microstructured polymer optical fibres. The emission properties of quantum dots within fibres have been explored to show that variation in concentration, sample length and pumping regimes effects the emission characteristics of these quantum dots. ...
4H-SiC Junction Barrier Schottky diode with embedded P-layer (JBS-EPL) is reported in this paper. JBS-EPL has attractive advantages, such as remarkably increasing the breakdown voltage and decreasing the power loss and die area comparing with conventional Junction Barrier Schottky diode. The estimates for power loss and die area are proposed that can be used for evaluating the different structure design of power devices. ...
