Compressed domain video processing for tile based panoramic streaming using HEVC (2015)

Panoramic streaming is a particular way of video streaming where an arbitrary Region-of-Interest (RoI) of high-spatial resolution videos is transmitted. It allows users to navigate interactively around the video and thus select anytime the portion of it they are interested in. The most basic approach consists of each user interacting with the system indicating the desired RoI. Then an encoder associated with each user encodes the desired RoI. However, such a system does not scale well. Instead, we consider tile based panoramic streaming, where users receive a set of tiles that match their RoI, and propose a low-complexity compressed domain video processing technique for tile based panoramic streaming using H.265/HEVC that generates a single video bitstream out of the selected tiles so that single hardware decoders can be used to decode the RoI video stream.
Structure Abnormality Of Fibrinogen Metz And Its Relationship To The Clotting Defect (1981)

Fibrinogen Metz was discovered in a young woman and was associated with a mild bleeding disorder and repeated abortions. Her parents are cousins and both have an abnormal fibrin formation but less intense than in the propositus. Fibrinogen Metz is therefore an homozygous case characterized by an unclottability of citrated sample, even in the presence of calcium and large quantities of thrombin. In addition, the clotting time is prolonged when the blood is collected in the absence of sodium citrate and the clot is extremely weak. By immunoenzymological assay, no release of fibrinopeptide A was noted after thrombin addition to purified fibrinogen. Furthermore, by disc electrophoresis in polyacrylamide gel in absence of SDS, an abnormal migration of the A α chain was observed. These results led us to analyze the sequence of the N terminal part of the A α chain by the Edman procedure. Arginine in position 16 was replaced by cysteine in fibrinogen Metz. This mutation localized on the site cleaved by thrombin explains the absence of fibrinopeptide A release, and the abnormal clottability of fibrinogen Metz.
A Solar Stationary Type IV Radio Burst and Its Radiation Mechanism (2018)

A stationary Type IV (IVs) radio burst was observed on September 24, 2011. Observations from the Nançay RadioHeliograph (NRH) show that the brightness temperature ( $T_{\mathrm{B}}$ ) of this burst is extremely high, over $10^{11}$ K at 150 MHz and over $10^{8}$ K in general. The degree of circular polarization ( $q$ ) is between $-60\% \sim -100\%$ , which means that it is highly left-handed circularly polarized. The flux–frequency spectrum follows a power-law distribution, and the spectral index is considered to be roughly $-3 \sim -4$ throughout the IVs. Radio sources of this event are located in the wake of the coronal mass ejection and are spatially dispersed. They line up to present a formation in which lower-frequency sources are higher. Based on these observations, it is suggested that the IVs was generated through electron cyclotron maser emission.
AB009. Prognostic outcomes and risk factors for patients with renal cell carcinoma and venous tumor thrombus after radical nephrectomy and thrombectomy: the prognostic significance of venous tumor thrombus level (2016)

Background: To evaluate the prognostic outcomes and risk factors for renal cell carcinoma (RCC) patients with venous tumor thrombus in China. Methods: We reviewed the clinical information of 256 patients who underwent radical nephrectomy and thrombectomy. Overall and cancer-specific survival rates were analyzed. Univariate and multivariate analyses were used to investigate the potential prognostic factors. Results: The median survival time was 45 months. The 5-year overall survival and cancer-specific survival rate were 44.2% and 47.2% for all patients. No matter for all patients or N0M0 patients, significant survival difference were observed between four different tumor thrombus levels, and between early (below hepatic vein) and advanced (above hepatic vein) tumor thrombus. Multivariate analysis demonstrated that higher tumor thrombus level (P=0.016, RR =1.58), N (P=0.013, RR =2.60), M (P<0.001, RR =4.14) stages and adrenal gland invasion (P=0.001, RR =4.91) were the most significant negative prognostic predictors. Conclusions: In this study, we reported the most cases of RCC patients with venous extension in China. We proved that patients with RCC and venous tumor thrombus may have relative promising long-term survival rate, especially for those with early tumor thrombus.
Use of a New Particle Contact Probability Filtration Rate Model to Determine the Effect of Particle Size Distribution in Filtration (1998)

ABSTRACT The Kozeny equation is commonly used to determine the rate of Filtration. This equation is derived from the Poiseuille equation, which states that the rate of filtration has a fourth-order dependency upon the pore radius. The Kozeny equation uses the Poiseuille equation with an average pore size determined based upon porosity and particle surface area. Because the pore sizes vary widely depending upon the particle size distribution, the use of an average pore size can lead to significant errors in determining the rate of filtration for samples with large changes in size distribution and small changes in surface area. In this study the Poiseuille equation was used together with the pore size distribution, which was calculated based upon particle contact probabilities, in order to more accurately determine the effect of size distribution on the filtration rate. Artificial particle size distributions of silica beads and gypsum particles were used at relatively low pressures to demonstrate the usefulness of the proposed model.
Biosynthesis of proteoglycans and their assembly into aggregates in cultures of chondrocytes from the Swarm rat chondrosarcoma. (1979)

Cultured chondrocytes from the Swarm rat chondrosarcoma incorporate [35S]sulfate into proteoglycans typical of hyaline cartilage. The movement of newly synthesized proteoglycans from inside the cells into the extracellular matrix and, finally, into the culture medium was examined by measuring the distribution of 35S-labeled proteoglycans in the medium, a 4 M guanidine HCl extract of the cell layer, and in the remaining residue for a number of chase times following a 5-min pulse with [35S]sulfate. When hyaluronate oligosaccharides containing greater than or equal to 10 monosaccharides were included in the chase media, a proportion of newly synthesized proteoglycans were displaced from the matrix (4 M extract) into the culture medium. This displacement was greatest when oligomers were in the chase media between 10 and 20 min after the pulse, approximately the time when the molecules are being secreted from the cells. The proportion of link-stabilized aggregate in the medium was examined by Sepharose 2B chromatography after adding an excess of unlabeled monomer which displaces labeled monomer from complexes with hyaluronate which are not link-stabilized. The proportion of link-stabilized aggregate increased from 12% to about 70% between 12 and 120 min of chase. The presence of 40 micron hyaluronate oligosaccharides of 16 monosaccharides in the chase media retarded but did not prevent aggregate formation. Oligomers of about 50 monosaccharides, which are large enough to bind both a monomer proteoglycan and a link protein, almost completely prevented the formation of the large link-stabilized aggregates. The results suggest: (a) newly synthesized proteoglycans are not bound into link-stabilized aggregates at the time of secretion; (b) hyaluronic acid oligomers which are long enough to interact only with the hyaluronic acid-binding site of proteoglycans will retard but not prevent link-stabilized aggregation; and (c) hyaluronic acid oligomers long enough to accommodate additionally a link protein form a link-stabilized ternary complex and prevent aggregation with larger hyaluronic acid molecules.

Bandwidth Efficient PIR from NTRU. (2014)

We present a private information retrieval (PIR) scheme based on somewhat homomorphic encryption (SWHE). In particular, we customize an NTRU-based SWHE scheme in order to evaluate a specific class of fixed depth circuits relevant for PIR implementation, thus achieving a more practical implementation. In practice, a SWHE that can evaluate a depth 5 circuit is sufficient to construct a PIR capable of retrieving data from a database containing 4 billion rows. We leverage this property in order to produce a more practical PIR scheme. Compared to previous results, our implementation achieves a significantly lower bandwidth cost (more than 1000 times smaller). The computational cost of our implementation is higher than previous proposals for databases containing a small number of bits in each row. However, this cost is amortized as database rows become wider.
Characterization of a discontinuous epitope on annexin II by site‐directed mutagenesis (1991)

Recombinant annexin II mutants were generated to identify amino acids involved in the formation of the discontinuous epitope of the monoclonal antibody H28. Analysis of the various mutant proteins by immunoblotting and enzyme-linked immunosorbent assay revealed that residues Lys27, Arg62, Glu65, and Arg67 are indispensable for H28 reactivity. Residues in equivalent positions are also in close proximity in the recently determined X-ray structure of annexin V, a different member of the same family of Ca2+/lipid-binding proteins. Thus annexins II and V show a similar three-dimensional folding in this region of the molecule. Consequently, the Ca2+ binding sites and the residues phosphorylated by pp60src (Tyr23) and protein kinase C (Ser25) most likely reside on opposite sides of the annexin II molecule.
The Noisy-Logical Distribution and its Application to Causal Inference (2007)

We describe a novel noisy-logical distribution for representing the distribution of a binary output variable conditioned on multiple binary input variables. The distri-bution is represented in terms of noisy-or’s and noisy-and-not’s of causal features which are conjunctions of the binary inputs. The standard noisy-or and noisy-and-not models, used in causal reasoning and artificial intelligence, are special cases of the noisy-logical distribution. We prove that the noisy-logical distribution is complete in the sense that it can represent all conditional distributions provided a sufficient number of causal factors are used. We illustrate the noisy-logical dis-tribution by showing that it can account for new experimental findings on how humans perform causal reasoning in complex contexts. We speculate on the use of the noisy-logical distribution for causal reasoning and artificial intelligence. 1
Complete Genome Assembly of Enterococcus faecalis 29212, a Laboratory Reference Strain (2014)

Enterococcus faecalis is a nonmotile Gram-positive coccus, found both as a commensal organism in healthy humans and animals and as a causative agent of multiple diseases, in particular endocarditis. We sequenced the genome of E. faecalis ATCC 29212, a commonly used reference strain in laboratory studies, to complete "finished" annotated assembly (3 Mb).
Hybrid hill-climbing and knowledge-based methods for intelligent news filtering (1996)

As the size of the Internet increases, the amount of data available to users has dramatically risen, resulting in an information overload for users. This work involved the creation of an intelligent information news filtering system named INFOS (Intelligent News Filtering Organizational System) to reduce the user's search burden by automatically eliminating Usenet news articles predicted to be irrelevant. These predictions are learned automatically by adapting an internal user model that is based upon features taken from articles and collaborative features derived from other users. The features are manipulated through keyword-based techniques and knowledge-based techniques to perform the actual filtering. Knowledge-based systems have the advantage of analyzing input text in detail, but at the cost of computational complexity and the difficulty of scaling up to large domains. In contrast, statistical and keyword approaches scale up readily but result in a shallower understanding of the input. A hybrid system integrating both approaches improves accuracy over keyword approaches, supports domain knowledge, and retains scalability. The system would be enhanced by more robust word disambiguation.

Computing correspondence based on regions and invariants without feature extraction and segmentation (2002)

The problem addressed is the matching of corresponding regions in two images, even when the image intensity may be smoothly varying without distinctive edges. Corresponding small regions are assumed to be related by affine transformations. The matching is done by using a new class of low computational cost affine invariants. This approach also computes the affine transformation, and is ideal for applications to 3-D motion estimation and 3-D surface reconstruction, image alignment, etc. No feature extraction, segmentation or epipolar constraint is required. The advantage of the authors' approach over area matching is that it handles large baselines, i.e., the distance between camera positions, where the differences in orientation and linear distortion of two areas being compared is large.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Synthesis of near-diffraction-free orbital-angular-momentum space-time wave packets having a controllable group velocity using a frequency comb (2022)

Novel forms of light beams carrying orbital angular momentum (OAM) have recently gained interest, especially due to some of their intriguing propagation features. Here, we experimentally demonstrate the generation of near-diffraction-free two-dimensional (2D) space-time (ST) OAM wave packets (ℓ = +1, +2, or +3) with variable group velocities in free space by coherently combining multiple frequency comb lines, each carrying a unique Bessel mode. Introducing a controllable specific correlation between temporal frequencies and spatial frequencies of these Bessel modes, we experimentally generate and detect near-diffraction-free OAM wave packets with high mode purities (>86%). Moreover, the group velocity can be controlled from 0.9933c to 1.0069c (c is the speed of light in vacuum). These ST OAM wave packets might find applications in imaging, nonlinear optics, and optical communications. In addition, our approach might also provide some insights for generating other interesting ST beams.
Handbook of Diagnostic and Structured Interviewing (2003)

Article AbstractFrom our regular book review column. With the advent of DSM-III-R, psychiatry committed itself to a quantitative and operational system. Although a dramatic increase in reliability was achieved, clinical diagnosis was, and is, still completely dependent on how the history of illness was obtained. Slight changes in inflection, in choice of language, and in sequence of questioning, coupled with clinicians†idiosyncratic choices as to what questions should be asked and determination of what answers are clinically relevant, result in unnecessary diagnostic variability. Structured interviews were designed to remedy this problem by organizing clinician inquiry and by limiting, as much as possible, sources of needless variance. As the author of this work notes, however, mindless adherence to structured interviews, at the cost of rapport and abandonment of clinical intuition, can result in a cure that is worse than the problem itself.
Estimating heading direction from monocular video sequences using biologically-based sensors (2016)

The determination of one's movement through the environment (visual odometry or self-motion estimation) from monocular sources such as video is an important research problem because of its relevance to robotics and autonomous vehicles. The traditional computer vision approach to this problem tracks visual features across frames in order to obtain 2-D image motion estimates from which the camera motion can be derived. We present an alternative scheme which uses the properties of motion sensitive cells in the primate brain to derive the image motion and the camera heading vector. We tested heading estimation using a camera mounted on a linear translation table with the line of sight of the camera set at a range of angles relative to straight ahead (0° to 50° in 10° steps). The camera velocity was also varied (0.2, 0.4, 0.8, 1.2, 1.6 and 2.0 m/s). Our biologically-based method produced accurate heading estimates over a wide range of test angles and camera speeds. Our approach has the advantage of being a one-shot estimator and not requiring iterative search techniques for finding the heading.
Stereoselective Syntheses of Highly Functionalized Bicyclo[3.1.0]hexanes:  A General Methodology for the Synthesis of Potent and Selective mGluR2/3 Agonists (2005)

[Chemical reaction: See text] A Et3Al mediated intramolecular epoxide opening, cyclopropanation reaction is described. The transformation provided highly functionalized bicyclo[3.1.0]hexane systems in high efficiency and with perfect H or F endo selectivity. Application of this reaction to the synthesis of mGluR2/3 agonist 1 (43% overall yield) and a few intermediates suitable for the synthesis of other bicyclo[3.1.0]hexane mGluR2/3 agonists is discussed.
Primary osteosarcoma of the heart with long-term survival: A case report of laparoscopic resection of a metastatic sarcoma in the intestine (2014)

Primary cardiac tumors are uncommon and cardiac osteosarcoma is a rare disease. While complete surgical resection is considered to be the best treatment option for cardiac osteosarcomas, local and metastatic recurrences present challenges and indicate a poor prognosis. A combination of surgical resection with radio- and/or chemotherapy is a more effective course of treatment for osteosarcoma. In the present case, the patient underwent a complete resection of a primary cardiac osteosarcoma, and received chemotherapy and radiotherapy following local recurrence and metastasis to the bone post-operatively. Following these treatments, a rectal metastatic tumor was detected as causative of anemia. There is currently a lack of guidelines on the treatment of metastatic osteosarcomas in the intestine and there are few reports on rectal metastases. The present study described a laparoscopic resection of the osteosarcoma. The patient recovered without any complications and radiotherapy and chemotherapy were administered post-surgery to treat the bone metastases. The patient remained healthy at a follow-up examination, 61 months post surgery.
&lt;title&gt;Silicon deformable mirrors and CMOS-based wavefront sensors&lt;/title&gt; (2000)

Inexpensive wavefront sensors and deformable mirrors are essential for addressing potential commercial applications for adaptive optics like laser beam control and ophthalmology. Silicon micromachined deformable mirrors offer the potential for low cost and high actuator density, but there are some problems with the architectures currently available like low mirror quality and high actuator crosstalk. Shack-Hartmann wavefront sensors are still based on traditional charge coupled device (CCD) arrays making them very expensive at high frame rates. To address the need for low cost deformable mirrors, we have implemented a new architecture of silicon deformable mirror designed to be low cost, have low actuator crosstalk, and still maintain good mirror quality. Furthermore, we built and tested a CMOS Shack-Hartmann wavefront sensor to address the needs of the adaptive optics community for high speed wavefront sensing.
Global Interactions in Random Field Models: A Potential Function Ensuring Connectedness (2010)

Markov random field (MRF) models, including conditional random field models, are popular in computer vision. However, in order to be computationally tractable, they are limited to incorporating only local interactions and cannot model global properties such as connectedness, which is a potentially useful high-level prior for object segmentation. In this work, we overcome this limitation by deriving a potential function that forces the output labeling to be connected and that can naturally be used in the framework of recent maximum a posteriori (MAP)-MRF linear program (LP) relaxations. Using techniques from polyhedral combinatorics, we show that a provably strong approximation to the MAP solution of the resulting MRF can still be found efficiently by solving a sequence of max-flow problems. The efficiency of the inference procedure also allows us to learn the parameters of an MRF with global connectivity potentials by means of a cutting plane algorithm. We experimentally evaluate our algorithm on both synthetic data and on the challenging image segmentation task of the PASCAL Visual Object Classes 2008 data set. We show that in both cases the addition of a connectedness prior significantly reduces the segmentation error.
