Value of contrast-enhanced ultrasonography in prostate cancer (2012)

Enhanced US modalities with intravenous contrast enhancement dramatically improve vascular imaging and resolution within the prostate. Targeted biopsies have higher yield for prostate cancer detection, and may prove useful for the initial evaluation of patients with elevated serum prostate-specific antigen levels, as well as for patients with persistently elevated prostate-specific antigen after negative prostate biopsy.
One index to dominate them all (2017)

Relational Database Management Systems (RDBMS) organize data into relations, representing them as tables. Most of queries executed over them are optimized by index structures. However, considering queries that require scanning indexes across multiple tables, the common approach involves scanning multiple indexes and combining their results, which is potentially costly, especially regarding similarity queries over complex data. This paper proposes a new type of index for modern RDBMS called domain index. Such proposal consists of indexes that allow searching columns of the same type, across multiple tables, with a single index scan, hence with superior performance. To evaluate our proposal, we carried out experiments (i) over a medical image dataset, to evaluate the performance in content-based similarity queries; and (ii) over a flow-based intrusion detection dataset, to evaluate the performance in conventional queries both in a real scenario and over synthetic data so to evaluate scalability. The results exhibit the higher performance of domain indexes. Specifically, the gains reached up to 42.9+ in similarity queries and up to 65.9+ in conventional queries. As the first paper on this subject, we expect this work to provide a basis for further developments on indexing techniques over domains of attributes within modern RDBMS.

Bonds and bridges : social and poverty (1999)

Using the lens of social capital-especially bridging or cross-cutting ties that cut across social groups and between social groups and government-provides new insights into policy design. Solidarity within social groups creates ties (bonding social capital) that bring people and resources together. In unequal societies, ties that cut across groups (bridging social capital) are essential for social cohesion and for poverty reduction. The nature of interaction between state and society is characterized as complementarity and substitution. When states are functional, the informal and formal work well together-for example, government support or community-based development. When states become dysfunctional, the informal institutions become a substitute and are reduced to serving a defensive or survival function. To move toward economic and social well-being, states must support inclusive development. Investments in the organizational capacity of the poor are critical. Interventions are also required to foster bridging ties across social groups-ethnic, religious, caste, or racial groups. Such interventions can stem from the state, private sector, or civil society and include: Changes in rules to include groups previously excluded from formal systems of finance, education, and governance, at all levels. Political pluralism and citizenship rights. Fairness before the law for all social groups together. Infrastructure that eases communication. Education, media, and public information policies that reinforce norms and values of tolerance and diversity.
6 cm 이상의 난소 유피낭종절제술에 있어서 골반경수술법과 개복수술의 비교 고찰 (1998)

1996년 3월 1일부터 1997년 4월 31일까지 전남대학교 의과대학 산부인과학교실을 내원하여 초음파검사, 컴퓨터 단층촬영영, 자기 공명 이미지 혹은 진단 복강경으로 6 cm 이상의 유피낭종으로 진단 받았던 45명의 환자를 대상으로 고안한 유피낭종의 내용물 유출을 최소화할 수 있는 골반경수술법을 이용하여 유피낭종을 난소에서 적출하여, 이를 기존의 개복수술을 통하여 유피낭종적출술을 받았던 환자 27명의 대조군과 비교하여 그 수술 시간, 입원 기간, 환자의 회복 속도 및 수술 후 낭종 내용물 유출에 의한 합병증을 관찰함으로써 다음과 같은 결론을 얻었다. 1. 개복수술에 의한 유피낭종적출술에 걸린 총 수 술 시간은 1.37 ± 0.7시간이었고, 수술골반경을 이 용하여 시행한 유피낭종적출술에 소요된 총 수술 시 간은 1.59 ± 0.4시간으로 통계적으로 유의한 차이를 발견할 수 없었다. 2. 수술 후 낭종 내용물의 유출에 의한 합병증은 개복수술이나 골반경 수술을 통한 유피낭종적출술을 시행한 경우에 전부 한 명도 없었다. 3. 수술 후 위장관의 운동이 정상으로 돌아오는 데 걸리는 시간은 개복수술의 경우는 1.9 ± 0.8일이 었고 수술 골반경의 경우는 1.0 ± 0.5일로써 수술골 반경의 경우가 통계적으로 유의하게 위장관의 회복 이 빨랐다(p ＜ 0.01). 4. 수술 후 진통제가 필요할 정도의 통증은 개복 수술의 경우는 2.7 ± 0.8일에 소실되었으나, 수술 골반경의 경우는 1.3 ± 0.4일에 소실되어 수술 골반 경에 의한 유피낭종 수술시 통계적으로 유의하게 빠 른 진통의 소실을 관찰할 수 있었다(p ＜ 0.01). 5. 수술과 관련하여 입원 기간은 개복수술의 경우 5.5 ± 0.7일이었고, 수술 골반경의 경우는 4.2 ± 0.4일로써 통계적으로 유의하게 입원 기간이 단축되 었다(p ＜ 0.01). 이상의 결과로 유피낭종의 내용물 유출을 최소화 하며 수술하는 방법을 사용한다면 수술 시간이 기존 의 개복수술과 별 다른 차이가 없어, 유피낭종적출 술은 수술 후 내용물 유출에 의한 합병증이 없고 빠 른 위장관 기능의 회복, 수술 통증의 빠른 소실, 입 원 기간의 단축 등의 이점이 많은 골반경 수술이 6 cm 이상의 큰 유피낭종일지라도 개복수술 보다는 더 권장할 만한 것으로 사료되었다.
An optimal ubiquitin-proteasome pathway in the nervous system: the role of deubiquitinating enzymes (2014)

The Ubiquitin-Proteasome Pathway (UPP), which is critical for normal function in the nervous system and is implicated in various neurological diseases, requires the small modifier protein ubiquitin to accomplish its duty of selectively degrading short-lived, abnormal or misfolded proteins. Over the past decade, a large class of proteases collectively known as deubiquitinating enzymes (DUBs) has increasingly gained attention in all manners related to ubiquitin. By cleaving ubiquitin from another protein, DUBs ensure that the UPP functions properly. DUBs accomplish this task by processing newly translated ubiquitin so that it can be used for conjugation to substrate proteins, by regulating the "where, when, and why" of UPP substrate ubiquitination and subsequent degradation, and by recycling ubiquitin for re-use by the UPP. Because of the reliance of the UPP on DUB activities, it is not surprising that these proteases play important roles in the normal activities of the nervous system and in neurodegenerative diseases. In this review, we summarize recent advances in understanding the functions of DUBs in the nervous system. We focus on their role in the UPP, and make the argument that understanding the UPP from the perspective of DUBs can yield new insight into diseases that result from anomalous intra-cellular processes or inter-cellular networks. Lastly, we discuss the relevance of DUBs as therapeutic options for disorders of the nervous system.
Wind power: how new technology is harnessing an age-old energy source (1974)

The major stumbling block to wind power utilization is cost-producing a wind generator that does not cost more per kwh than a coal-steam or nuclear plant. three trends are noted: single site, power production with battery storage (1-6 kw outputs); multimode commercial power combining electrolysis of water to make hydrogen and possibly fuel cells, or a turbine to convert back to electricity or mechanical power; and megawatt-size wind turbines feeding ac directly to the main power bus. several systems are described.

Noisy motion vectors removal for reliable camera parameters estimation in MPEG coded videos (2003)

We face the problem of the estimation of camera motion parameters from MPEG compressed streams. The most common approach relies on the use of the motion vectors defined in the P and B coded frames of the MPEG streams. In this way, the computational efficiency of the whole process is improved. However, in some specific situations the motion vectors do not represent the real motion of the intercoded macroblock; thus, it is important to detect and remove such noisy macroblocks (outliers) in order to obtain reliable camera motion estimation. Hence, we present a simple method for outliers removal. Some preliminary experiments are reported that demonstrate the effectiveness of the proposed technique.
Cross Layer Design for OFDMA Systems Using the Beta-Min-Sum Belief Propagation Algorithm (2007)

This paper investigates the problem of resource allocation and scheduling for an orthogonal frequency division multiple access (OFDMA) broadband wireless network We formulate a utility-based cross-layer resource management framework that exploits instantaneous channel state information at the base station in order to schedule traffic during each frame. During each decision epoch, the objective is to find an efficient and fair rate and sub-carrier allocation policy that maximizes the average network utility subject to certain constraints. We develop an equivalent graph theoretical model for the cross-layer assignment problem and show its equivalence to the classical problem of finding the maximum weight matching (MWM) on a bipartite graph. This is a well-studied problem in classical graph theory and several well-known solutions exist. For the optimal assignment, we consider the Hungarian algorithm - which always achieves the maximal network utility - and compare its performance to a sub-optimal modified min-sum belief propagation algorithm. Through simulations, we demonstrate the negligible difference in performance between the two.
Data truncation artifact reduction in MR imaging using a multilayer neural network (1993)

A magnetic resonance image (MRI) may contain truncation artifacts if there are not enough high-frequency data when the conventional Fourier transform method is used for reconstruction. A method for reducing the artifacts using a multilayer neural network is presented. The network consists of one linear output layer and at least one nonlinear hidden layer. The missing high-frequency components are predicted based on known low-frequency components and are used to reduce the truncation artifacts of the image. Results from a series of simulation experiments are discussed.

Evaluation of recent temperature and pressure data from wells in Tendaho geothermal field, Ethiopia and from well HG-1 at Hágöngur, Iceland (2004)

The Tendaho geothermal field is a geothermal prospect area in N-Ethiopia, which has both shallow and deep wells. Detailed analysis of downhole temperature data from the wells shows that the hottest part of the well field is in the vicinity of well TD5. The reservoir pressure is also at maximum in the same area suggesting an upflow zone near well TD5. Data from short term production tests of wells TD5 and TD6 were analysed. The results of well TD5 discharge indicate an average thermal output of 24.5 MWt at 18 bar-g wellhead pressure. This suggests that TD5 is capable of producing 2.4 MW of electricity. Generally, the wellhead pressures are stable at well shut-in conditions except for wells TD5 and TD6. TD5 showed rising wellhead pressure in 2002 and 2003. Hagongur is a geothermal area located in Central Iceland. Surface exploration started in 1995 with a reconnaissance geological survey and mapping of the geothermal manifestations because of plans to construct a hydro dam in the area. The studies suggested the presence of a central volcano, and a semi-circular alignment of rhyolitic domes implies the possibility of an underlying caldera. A transient electromagnetic (TEM) resistivity survey indicates a subsurface hightemperature geothermal anomaly in an area covering 20-40 km 2 . Sampling and analyses of gas and fluid from geothermal manifestations indicated subsurface temperatures up to 290°C. The first well, HG-1, was drilled to 2360 m depth in 2003 in the central part of the anomaly. The observed bottom hole temperature is over 310°C.
Comparative results with massively parallel spatially-variant maximum likelihood image restoration. (1995)

We present results of concurrent maximum likelihood restoration implementations with spatially-variant point spread function (SV-PSF), exhibiting performance superior to restoration with invariant PSF. We realize concurrency on a network of Unix workstations, and a SV-PSF model from sparse PSF reference information by means of bilinear interpolation. We then use the interpolative PSF model to implement several different SVPSF restoration methods. These restoration methods are tested on a standard Hubble Space Telescope test case, and the results are compared on a computational effort/restoration performance basis. 1 Introduction Consider an optical (intensity) field O(x 0 ) incident on an optical system as a function of the source point x 0 . The optical system produces an image I(x), a function of field point x. The impulse response or point-spread function (PSF) of the optical system, P (x; x 0 ), is in general a function of both source and field location, and relates O and I...
Off-line Supercritical Fluid Extraction and Capillary Gas Chromatography of Pyrrolizidine Alkaloids in Senecio Species (1991)

The pyrrolizidine alkaloid (PA) fraction of two Senecio species (Senecio inaequidens and Senecio cordatus) was extracted by off-line supercritical fluid extraction (sfe) and analyzed by capillary gas chromatography. Sfe was carried out with a home-assembled apparatus, using MeOH/CO2 as extraction medium, at 55-degrees and 15 MPa. Compared to the classical MeOH Soxhlet extraction, this technique requires a smaller sample amount and provides a quicker extraction, a simplified PA fraction clean-up, and a higher recovery.
Reactions with 2‐mercaptopyrimidines. Synthesis of some new thiazolo[3,2‐<i>a</i>]‐ and triazolo[4,3‐<i>a</i>]pyrimidines (1987)

Abstract Alkylation of 5‐cyano‐4‐oxo‐6‐phenyl‐2‐thioxo‐1,2,3,4‐tetrahydropyrimidine I with methyl iodide, chloroacetic acid or 3‐chloro‐2,4‐pentanedione, afforded the S ‐alkyl derivatives IIa‐c. 2‐Carboxymethylthio and 2‐(2′,4′‐dioxopentan‐3‐ylthio) derivatives IIb and IIc could be cyclised by acetic anhydride or polyphosphoric acid to give 6‐cyano‐3,5‐dioxo‐5 H ‐7‐phenylthiazolo[3,2‐ a ]pyrimidine III and 2‐acetyl‐6‐carboxamido‐5 H ‐3‐methyl‐7‐phenylthiazolo[3,2‐ a ]pyrimidine‐5‐one IX , respectively. Benzoylation of 2‐hydrazinopyrimidine derivative XII , in anhydrous dioxan, afforded the N ‐benzoyl derivative XIII , which could be cyclised by heating in dimethylformamide to give 5‐amino‐6‐cyano‐3,7‐diphenyl‐ s ‐triazolo[4,3‐ a ]pyrimidine ( XIV ). The 2‐hydrazinopyrimidine derivatives XII and XV reacted with benzoyl isothiocyanate in dioxane to yield 4‐benzoylthiosemicarbazide derivatives XVI and XVII , which were converted into the 2‐ s ‐trizolopyrimidine derivatives XVIII and XIX , respectively. Also, XVI and XVII reacted with 2,4‐pentanedione and 3‐chloro‐2,4‐pentanedione to yield 2‐pyrazolopyrimidine derivatives XX and XXI , respectively.
The Yielding of Waxy Crude Oils (1998)

The yielding process of statically cooled waxy crude oil was examined in detail. Three direct measurementsa controlled stress test, a creep−recovery test, and an oscillatory testwere employed using a controlled stress rheometer to investigate the yielding of two distinctly different statically cooled waxy crude oils. The results showed that yielding of waxy crude oil occurs by an initial elastic response, followed by viscoelastic creep and a final fracture. A model with an elastic-limit yield stress, a static yield stress, and a dynamic yield stress was introduced to describe the yielding process. The three yield stresses were determined by means of different techniques. The effect of the time scale in different measurements on the three yield stresses was studied. It was shown from both the creep−recovery and oscillatory tests that the elastic-limit yield stress was independent of the time scale. The static yield stress was found to be dependent on the time scale in the three tests. The dynamic yield stress measured only with the controlled stress test was also found to be dependent on the time scale of the yielding. Good reproducibility can be obtained in these tests by strictly controlling the thermal and shear history of the samples.
Modification of Blood Flow to the Extremities by Electrical Stimulation of the Nervous System (1976)

Sixteen patients who had electrical stimulation applied to various portions of the nervous system were examined for increase in blood flow to the extremities. Clinical observations and a one-channel plethysmograph were used to measure arterial dilatation. Seven patients had transcutaneous stimulation applied over the cervical or thoracic spinal cord, peripheral nerves, or low lumbar region; eight had electrical stimulators implanted over the spinal cord in attempts to relieve intractable pain or some of the symptoms of multiple sclerosis; and one patient had electrical stimulators implanted over the C-6 dorsal roots for small artery disease of the upper extremities. Twelve of 13 patients who had electrical stimulation applied to the spinal cord or dorsal roots had significant arterial dilatation in one or more extremities. Electrical stimulation applied to the ulnar nerves did cause arterial dilatation. One patient did not show any change in the central arterial pressure curve during transcutaneous stimulation of the cervical spinal cord.
A Cluster Operating System Based on Software COMA Memory Management (2007)

Clusters of SMPs are attractive for executing shared memory parallel applications but reconciling high performance and ease of programming remains an open issue. A possible approach is to provide an efficient Single System Image operating system giving the illusion of an SMP machine. In this paper, we present such a system focusing on global management of the memory resource. We introduce the concept of container at the lowest operating system level to build a COMA-like memory management subsystem. Higher level operating system services such as virtual memory system and file cache can be easily implemented based on containers and transparently take benefit of the whole memory resource available in the cluster.
Laparoscopic appendectomy using a polymeric clip to close the appendicular stump. (2007)

An efficient CORDIC array structure for the implementation of discrete cosine transform (1995)

We propose a novel implementation of the discrete cosine transform (DCT) and the inverse DCT (IDCT) algorithms using a CORDIC (coordinate rotation digital computer)-based systolic processor array structure. First, we reformulate an N-point DCT or IDCT algorithm into a rotation formulation which makes it suitable for CORDIC processor implementation. We then propose to use a pipelined CORDIC processor as the basic building block to construct l-D and 2-D systolic-type processor arrays to speed up the DCT and IDCT computation. Due to the proposed novel rotation formulation, we achieve 100% processor utilization in both 1-D and 2-D configurations. Furthermore, we show that for the 2-D configurations, the same data processing throughput rate ran be maintained as long as the processor array dimensions are increased linearly with N. Neither the algorithm formulation or the array configuration need to be modified. Hence, the proposed parallel architecture is scalable to the problem size. These desirable features make this novel implementation compare favorably to previously proposed DCT implementations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Leukotriene A4 hydrolase: an anti-inflammatory role for a proinflammatory enzyme (2011)

Neutrophils represent a prominent source of pathology in an array of persistent pulmonary diseases. A recent article published in Science describes a novel anti-inflammatory pathway that degrades the neutrophil chemoattractant Pro-Gly-Pro (PGP) to limit neutrophilic inflammation of the lung. Degradation of PGP was mediated through the action of leukotriene A4 hydrolase (LTA4H), an enzyme classically recognised for its capacity to generate another neutrophil chemoattractant, leukotriene B4 (LTB4). The same enzyme therefore has opposing proinflammatory (LTB4 generation) and anti-inflammatory (PGP degradation) activities that govern neutrophilic inflammation. Intriguingly, cigarette smoke, a key risk factor for the development of chronic obstructive pulmonary disease, impedes PGP degradation but not LTB4 generation by LTA4H. Cigarette smoke therefore essentially converts LTA4H into an exclusively proinflammatory enzyme, whereby both PGP and LTB4 can drive persistent neutrophila observed in chronic obstructive pulmonary disease. In recent years there has been significant pharmaceutical interest in the development of LTA4H inhibitors to alleviate LTB4-mediated pathologies. In light of these new findings, such strategies should be viewed with caution since they may inadvertently prevent PGP degradation and promote chronic neutrophilic inflammation.
