Management Of Schema Evolution In Databases (1991)

This paper presents a version model which handles database schema changes and which takes evolution into account. Its originality is in allowing the development of partial schema versions, or views of a schema. These versions are created in the same database from a common schema. We define the set of authorised modifications on a schema and the rules which guarantee its coherence after transformation. Mechanisms allowing data to be associated with each version are also integrated in the model.
[Efficacy of percutaneous ethanol injection therapy in Korean with hepatocellular carcinoma]. (2003)

These results demonstrate that PEIT is therapeutically useful in patients with HCC less than 4 in number and less than 3 cm in diameter. However, since multiple or large tumors are associated with low tumor-free survival or high local recurrence rates, PEIT for these tumors and the subsequent post-treatment follow-up should be performed carefully.
Isolation and Characterization of Sequences from Mouse Chromosomal DNA with ARS Function in Yeasts (1983)

Fragments of chromosomal DNA from a variety of eucaryotes can act as ARSs (autonomously replicating sequence) in yeasts. ARSs enable plasmids to be maintained in extrachromosomal form, presumably because they function as initiation sites for DNA replication. We isolated eight different sequences from mouse chromosomal DNA which function as ARSs in Saccharomyces cerevisiae (bakers' yeast). Although the replication efficiency of the different mouse ARSs in yeasts appears to vary widely, about one-half of them functions as well as the yeast chromosomal sequence ARS1. Moreover, five of the ARSs also promote self replication of plasmids in Schizosaccharomyces pombe (fission yeast). Each of the ARSs was cloned into plasmids suitable for transformation of mouse tissue culture cells. Plasmids were introduced into thymidine kinase (TK)-deficient mouse L cells by the calcium phosphate precipitation technique in the absence of carrier DNA. In some experiments, the ARS plasmid contained the herpes simplex virus type 1 TK gene; in other experiments (cotransformations), the TK gene was carried on a separate plasmid used in the same transformation. In contrast to their behavior in yeasts, none of the ARS plasmids displayed a significant increase in transformation frequency in mouse cells compared with control plasmids. Moreover, only 1 of over 100 cell lines contained the original plasmid in extrachromosomal form. The majority of cell lines produced by transformation with an ARS TK plasmid contained multiple copies of plasmid integrated into chromosomal DNA. In most cases, results with plasmids used in cotransformations were similar to those for plasmids carrying TK. However, cell lines produced by cotransformations with plasmids containing any one of three of the ARSs (m24, m25, or m26) often contained extrachromosomal DNAs.
Alterations of T cell activation signalling and cytokine production by postmenopausal estrogen levels (2009)

Jurkat T cells exposed to 4 pg/ml E(2) expressed significantly diminished activation signalling proteins, correlating with reduced IL-2 production. Lower signalling protein levels appear to result from decreased CD3-zeta, JAK2, and JAK3 gene expressions. These findings may provide a molecular basis for immunosenescence associated with the postmenopausal state.
Normalized Metadata Generation for Human Retrieval Using Multiple Video Surveillance Cameras (2016)

Since it is impossible for surveillance personnel to keep monitoring videos from a multiple camera-based surveillance system, an efficient technique is needed to help recognize important situations by retrieving the metadata of an object-of-interest. In a multiple camera-based surveillance system, an object detected in a camera has a different shape in another camera, which is a critical issue of wide-range, real-time surveillance systems. In order to address the problem, this paper presents an object retrieval method by extracting the normalized metadata of an object-of-interest from multiple, heterogeneous cameras. The proposed metadata generation algorithm consists of three steps: (i) generation of a three-dimensional (3D) human model; (ii) human object-based automatic scene calibration; and (iii) metadata generation. More specifically, an appropriately-generated 3D human model provides the foot-to-head direction information that is used as the input of the automatic calibration of each camera. The normalized object information is used to retrieve an object-of-interest in a wide-range, multiple-camera surveillance system in the form of metadata. Experimental results show that the 3D human model matches the ground truth, and automatic calibration-based normalization of metadata enables a successful retrieval and tracking of a human object in the multiple-camera video surveillance system.

China's Foreign Aid in 1979-80 (1976)

CoNTEMPORARY AsiAN STUDIES SERIES and some nations that are not considered rich nations, such as Australia and Argentina. 4ecause of the emphasis put upon domestic economic development, much less was said about economic assistance to other countries by Chinese leaders or by the media in China.Thus, while China has always been reluctant to announce its aid promises for a variety of reasom;, including the fact that it wants to avoid comparisons with aid given by the richer countries and maintain the image of giving aid without strings attached, it has recently become even more reticent in providing details about its aid giving.Hence officially announced bilateral aid in 1979 and 1980 was down from previous years. (See Table 1).In 1979 China provided between $99 and $112 million in aid to other countries that it or the recipient country provided figures on, and this included only two nations.(See Table 2).In 1980 the figure was smaller, or a total of $89.5 million in official aid, with four recipients.(See Table 3).And in the case of only one of the recipients during this two year period was the announcement made in China -an interest free loan to Zimbabwe.On the other hand, Beijing made public most of its RP.d Cross and other emergency aid, which exceeded previous years, and, if added to China's official aid giving, would bring the total of officially announced aid up slightly.Funds China provided to U.N.-affiliated and other international organizations were considerably larger than emergency aid, especially in 1980, and, if added to China's aid program, would increase the total figure noticeably.Finally, if the costs borne by China for resettling ethnic Chinese among the Indo-Chinese refugees is counted, China's aid program increases by several fold.Further details on these points are provided in subsequent pages.----~npast years, official aid figures tell very little about China's foreign aid program and during 1979-80 this remained true.Most of China's aid giving was unannounced and its real aid exceeded by several fold the amount that can be documented in terms of values and conditions or terms.On the other hand, like its official aid giving, China's real aid also declined appreciably.Two factors explain this drop: (1) the termination of aid to Vietnam and Albania -the , 4. In June 1980 Argentina extended China credits totalling $300 million to buy non-traditional goods.The rate of interest was 7V2 percent for capital goods and 3 1 /2 percent for durable and semi-durable goods, and the repayment period was 81/2 and 10 years respectively.For further details see New China
Fibre Optic Sensors Using Adiabatically Tapered Single Mode Fibres (1994)

A tapered single-mode fibre optic device was investigated for use as an intrinsic pH sensor. The sensing process is based on the detection of evanescent-wave excited fluorescence energy from an indicator dye circulating the taper. Appropriate selection of dye and taper parameters have allowed the sensor to perform well in harsh chemical environments, with near-real-time response. Future work could include immobilisation schemes for the indicator as well as other sensor types, such as pCa. Further optical properties of the tapered fibre will also be investigated.
Patch Testing With a Routine Screening Tray in North America, 1985 Through 1989: II. Gender and Response (1991)

Patients with suspect allergic contact dermatitis (2,306 women and 1,743 men) were patch tested in 14 clinics in North America between August 1985 and July 1989. While allergic contact dermatitis was equally represented in the two genders, irritant contact dermatitis and occupational dermatitis were more common in men. Hand, foot, and generalized skin eruptions were more common in men while face, neck, and eyelids were more common locations in women. Differences in the frequency of response to 13 of the test chemicals in the two genders were evident.

MRI techniques for cardiovascular imaging (1999)

Over the last several years, cardiovascular MRI has benefited from a number of technical advances which have improved routine clinical imaging techniques. As a result, MRI is now well positioned to realize its longstanding promise of becoming the comprehensive cardiac imaging test of choice in many clinical settings. This may be achieved using a combination of basic advanced techniques. In this overview, the basic cardiac MRI techniques which are clinically useful are reviewed, and the recent technical advances which are clinically promising are described. These advances include routine black blood and cine bright blood techniques that are high speed (<10s per black blood image or cine slice), multislice whole heart perfusion imaging methods, and recently emerging real-time imaging methodologies.

The Exposure-Defocus Forest (1994)

The exposure-defocus (E-D) forest, a large cluster of E-D trees, is a valuable lithography characterization tool. With the E-D forest, processing parameters are compressed into relevant ones that are significant for manufacturing. It forms a universal quantitative base for comparison of lithographic performance, hence an essential vehicle to analyze and optimize the imaging performance of lithographic systems. This paper shows the physical meaning of the E-D space and the construction of E-D tree and E-D forest from aerial, developed, or etched images either from simulation or from experimental linewidth measurement results. The performance criteria based on E-D trees and optimization in depth of focus, exposure latitude, and E-D window area, are explained. The significance of dealing with an entire E-D forest, instead of single trees, is shown. The difference between linewidth-based and edge-based E-D trees is given. Examples of E-D forest application include: Determining the mutual dependence of depth of focus and exposure latitude; Optimizing the imaging lens numerical aperture and the degree of partial coherence; Determining the resist operation window; Characterizing and reducing optical proximity effects; Evaluating phase shifting masks; Optimizing off-axis illumination; and Comparing the performance of optical and X-ray lithography.
An aerial image segmentation approach based on enhanced multi-scale convolutional neural network (2019)

Aerial images are the images captured from high attitudes above the ground. Processing and analyzing aerial images play central roles in terrain modeling, agricultural monitoring, city planning, environmental surveillance, etc. Aerial images are developing towards high resolution and large size, which poses a major challenge in pixel-level image segmentation. With the rapid development of deep learning technology, the application of deep learning to image semantic segmentation has obtained satisfactory effect. In this paper, we propose a novel aerial image segmentation method based on convolutional neural network (CNN). The main structure of the proposed network adopts U-Net. In order to capture objects of different scales in the deep features, a group of cascaded dilated convolution is inserted at the bottom of U-Net which has different dilation rates. Furthermore, to better optimize the network at different scales, an auxiliary loss function is proposed to be integrated in the cascaded dilated convolution. The effectiveness of the proposed method is evaluated on the Inria Aerial Image Labeling Dataset. Experiment results show that the proposed method has better segmentation performance than existing approaches.
Zinc complexes of fluorous alkoxide-imino ligands: Synthesis, structure, and use in ring-opening polymerization of lactide and β-butyrolactone (2009)

The reaction of fluorous imino-alcohols {ON(R1,R2)}H (R(1) = Me, Ph; R(2) = Ph, CH(2)Ph, cyclohexyl, piperidinyl) with Zn(N(SiMe(3))(2))(2) (1 or 0.5 equiv) systematically led to bis(ligand) complexes Zn{ON(R1,R2)}(2) (1-9), which were isolated in 84-88% yield. Imino-alcohols {ON(R1,R2)}H react selectively with ZnEt(2) to give the corresponding complexes {ON(R1,R2)}ZnEt (4-7), in 74-78% yield. The stability of complexes 4-7 appears to be controlled by the nature of the substituent at the imine N atom: a phenyl group leads to slow ligand redistribution while alkyl-type substituents (benzyl, cyclohexyl, piperidinyl) prevent this disproportionation. Treatment of 5 with isopropanol afforded {ON(Ph,Bn)}Zn(OiPr) (8) in modest yield, due to rapid ligand redistribution. Complexes 1-8 were authenticated by elemental analysis, (1)H, (19)F and (13)C NMR spectroscopy in solution, and single-crystal X-ray diffraction studies for 1, 3, 5, 7 and 8. In situ combinations of {ON(Ph,Bn)}ZnEt (5)/BnOH and Zn{ON(Ph,Bn)}(2) (2)/BnOH are active systems for the ROP of racemic lactide and beta-butyrolactone at 20-50 degrees C, yielding atactic polylactide and poly(3-hydroxybutyrate) with good molecular weight control (M(n) up to 20,700 g/mol) and relatively narrow molecular weight distributions (M(w)/M(n) = 1.06-1.57). These binary systems also allow the immortal ROP of lactide and beta-butyrolactone, using excess alcohol (up to 5 equiv) vs the Zn catalyst.
Successive Cancellation of Power Amplifier Distortion for Multiuser Detection (2010)

This paper presents an iterative interference suppression technique to cancel power amplifier (PA) distortion at the receiver. The focus is mainly on single carrier frequency division multiple access systems, and on removing the distortion created by adjacent users' power amplifier. It is assumed that the receiver has perfect knowledge of all the users' transmitter power amplifier nonlinearities. By relaxing the requirement on PA linearity at the mobile terminals, the PA power efficiency can be improved. The simulations show that by utilizing the successive interference cancelation technique, the require signal to noise ratio required to achieve 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> symbol error rate is decreased by 3 - 4 dB. By using a clipped communication signal instead of backing off the power in the transmitter PA, we are able to improve the power added efficiency by 8 percentage points.
Friendly Neighbors: Contextualized Sequence-to-Sequence Link Prediction (2023)

We propose KGT5-context, a simple sequence-to-sequence model for link prediction (LP) in knowledge graphs (KG). Our work expands on KGT5, a recent LP model that exploits textual features of the KG, has small model size, and is scalable. To reach good predictive performance, however, KGT5 relies on an ensemble with a knowledge graph embedding model, which itself is excessively large and costly to use. In this short paper, we show empirically that adding contextual information — i.e., information about the direct neighborhood of the query entity — alleviates the need for a separate KGE model to obtain good performance. The resulting KGT5-context model is simple, reduces model size significantly, and obtains state-of-the-art performance in our experimental study.

<i>In Situ</i> Observation of the Phase Transformations in Ti15Mo Alloy Deformed by High Pressure Torsion (2018)

Metastable β-Ti alloys including Ti15Mo alloy are perspective candidates for use in medical applications. During thermal treatment Ti15Mo alloy undergoes various phase transformations. After solution treatment it contains metastable β-phase and ω-phase. During annealing the ω-phase partially dissolves as well as stable α-phase particles are formed. The solution treated Ti15Mo alloy was deformed by high pressure torsion (HPT) at room temperature. Significant grain refinement with grain size of ~100 nm was achieved even after 1/4 of HPT rotation. The effect of the ultra-fine grained (UFG) structure achieved by HPT on the phase transformations was studied by differential scanning calorimetry (DSC) and transmission electron microscopy (TEM) during in-situ heating. High density of lattice defects, dense network of grain boundaries as well as ongoing recovery and recrystallization upon heating significantly affected the phase transitions. Observation of the microstructure during in-situ heating in TEM revealed no representative changes in transparent part of the sample due to the “thin foil effect”.
[Examination of human herpesvirus-6 antibody in blood patients serum]. (1999)

To know the infection state of human herpesvirus-6(HHV-6) in leukemia, lymphoma, myeloproliferative disorder syndrome, and multiple myeloma, indirect fluoroimmunoassay was taken to examine the rate of HHV-6's antibody. The results were that: the patient's rate of HHV-6 antibody was 75.6% (149/197), the blood donor's rate was 45.6% (115/252), there was a significant difference between them (P < 0.01). The results show that the examined patients are infected by HHV-6, which has a good relationship with leukemia, lymphoma, myeloproliferative disorder syndrome, and multiple myeloma.
Non-HDL C equals apolipoprotein B: except when it does not! (2010)

Thus, our conclusion is that apoB and non-HDL C are equal - except when they are not. Because apoB allows greater specificity of diagnosis and therapy, it re-establishes the primacy of individuals over groups as the objects of our study and our care and that may be its most important contribution to clinical lipidology.
Micro-stereolithography of dot shapes for lightguide using LCD grayscale mask (2005)

In this study, a novel microfabrication method that is micro-stereolithography using a LCD grayscale mask has been proposed. Light transmittance distribution with the LCD grayscale mask can be varied with that level of grayscale. Accordingly, a grayscale pattern of the LCD mask is responsible for an intensity distribution of an exposure pattern. This method has realized a fabrication of the prismatic shaped dot with the size of 18µm in width and 15µm in height. Consequently, the feasibility of the microfabrication was experimentally confirmed for the lightguide with high light guiding efficiency used in LCD backlight unit.
Comparative in vitro activity of moxalactam, cefotaxime, cefoperazone, piperacillin, and aminoglycosides against gram-negative bacilli (1980)

The in vitro activities of four new beta-lactam antimicrobial agents (moxalactam, cefotaxime, cefoperazone, and piperacillin) and the aminoglycosides against 744 recent clinical isolates of facultative gram-negative bacilli were compared simultaneously by the agar dilution method. The major in vitro difference of these newer beta-lactam compounds appeared to be their antipseudomonal activity; cefoperazone was the most active, whereas cefotaxime had the least potency. The aminoglycosides, however, had the most effective in vitro activity on a weight basis against Pseudomonas aeruginosa.
Phenformin has anti-tumorigenic effects in human ovarian cancer cells and in an orthotopic mouse model of serous ovarian cancer (2020)

Obesity and diabetes have been associated with increased risk and worse outcomes in ovarian cancer (OC). The biguanide metformin is used in the treatment of type 2 diabetes and is also believed to have anti-tumorigenic benefits. Metformin is highly hydrophilic and requires organic cation transporters (OCTs) for entry into human cells. Phenformin, another biguanide, was taken off the market due to an increased risk of lactic acidosis over metformin. However, phenformin is not reliant on transporters for cell entry; and thus, may have increased potency as both an anti-diabetic and anti-tumorigenic agent than metformin. Thus, our goal was to evaluate the effect of phenformin on established OC cell lines, primary cultures of human OC cells and in an orthotopic mouse model of high grade serous OC. In three OC cell lines, phenformin significantly inhibited cellular proliferation, induced cell cycle G1 arrest and apoptosis, caused cellular stress, inhibited adhesion and invasion, and activation of AMPK and inhibition of the mTOR pathway. Phenformin also exerted anti-proliferative effects in seven primary cell cultures of human OC. Lastly, phenformin inhibited tumor growth in an orthotopic mouse model of serous OC, coincident with decreased Ki-67 staining and phosphorylated-S6 expression and increased expression of caspase 3 and phosphorylated-AMPK. Our findings demonstrate that phenformin has anti-tumorigenic effects in OC as previously demonstrated by metformin but it is yet to be determined if it is superior to metformin for the potential treatment of this disease.
Reliability-based micromechanical small crack growth model (1999)

A probabilistic small crack growth fatigue model is proposed in which a small crack is defined as a crack of size comparable to the microstructure. The model relates the microstructural material heterogeneities to the statistical scatter in the macrostructural response. The microstructure is explicitly modeled with microelements that represent the grains of a single phase alloy. The properties of the grain such as size, orientation, and frictional strength are modeled as random variables. The macrostructure is modeled as an ensemble of microelements. A cracktip opening displacement model based on the assumption of continuously distributed dislocations is used to determine the small crack growth rate. The models are combined in a Monte Carlo simulation to determine the statistical distribution of short crack growth fatigue response of the macrostructure. The modeled response is compared to the trends in experimental observations from the literature. The purpose of the study is to investigate only the microstructural effects. Variations in the applied loading, stress concentrations! residual stresses, and global geometry are not consrdered.
