On utility of inductive learning in multiobjective robust design (1999)

Most engineering design problems involve optimizing a number of often conflicting performance measures in the presence of multiple constraints. Traditional vector optimization techniques approach these problems by generating a set of Pareto-optimal solutions, where any specific objective can be further improved only at the cost of degrading one or more other objectives. The solutions obtained in this manner, however, are only single points within the space of all possible Pareto-optimal solutions and generally do not indicate to designers how small deviations from predicted design parameters settings affect the performance of the product or the process under study. In this paper we introduce a new approach to robust design based on the concept of inductive learning with regression trees. Given a set of training examples relating to a multiobjective design problem, we demonstrate how a multivariate regression tree can utilize an information-theoretic measure of covariance complexity to capture optimal, tradeoff design surfaces. The novelty of generating design surfaces as opposed to traditional points in the design space is that now designers are able to easily determine how the responses of a product or process vary as design parameters change. This ability is of paramount importance in situations where design parameter settings need to be modified during the lifetime of a product/process due to various economic or operational constraints. As a result, designers will be able to select optimal ranges for design parameters such that the product's performance indices exhibit minimal or tolerable deviations from their target values. To highlight the advantages of our methodology, we present a multiobjective example that deals with optimum design of an electric discharge machining (EDM) process.

A Method of Bucket Index over Encrypted Character Data in Database (2007)

The encryption mechanism is the common method to protect the sensitive data in database from various attacks. But once the data in databases is encrypted, the efficiency of DBMS will fall. To enhance the security of the sensitive data and to improve the efficiency of the encrypted database, one effective method is to build index on the encrypted field, and firstly executes the query on the index to get fewer records to decrypt in this paper. This paper proposes an index mechanism of bucket index on the character data, which has close relationships with all of its characters. The index tries to translate the character string into a numeric data, on which the primary query will be processed to filtrate the records roughly. Only the rest records need to be decrypted, and it will save lots of time. So the cipher index can improve the query efficiency greatly.
Face detection based on template matching and support vector machines (2002)

A face detection algorithm integrating template matching and support vector machines (SVM) is presented. Two types of templates: eyes-in-whole and face itself, are used for coarse filtering, and the SVM classifier is used for classification. A bootstrap method is used to collect non-face samples for SVM training under a template matching constrained subspace, which greatly reduces the complexity of training the SVM. Comparative experimental results demonstrate its effectiveness.

Electric field effects on alignment of lamellar structures in diblock copolymer thin films studied by neutron scattering (2006)

Wir untersuchten die Orientierung von Lamellen in dünnen Filmen eines P(S-b-MMA)-Copolymers unter dem Einfluss von Oberfläche und senkrecht zur Oberfläche angelegtem elektrischen Feld. Die Oberfläche richtet die Lamellen parallel zur Oberfläche aus, während das elektrisch Feld die Lamellen senkrecht zur Oberfläche ausrichtet. Mit Neutronenreflektometrie, diffuser Neutronenstreuung, und Neutronenkleinwinkelstreuung wurde die Struktur der Filme quantitativ analysiert. Die Filmdicke hat einen grossen Einfluss auf die Struktur der Filme. Nach dem Tempern wird eine komplette Orientierung durch die Oberfläche in den dünnen Filmen beobachtet. Die parallele Orientierung bleibt auch dann stabil wenn ein elektrisches Feld mit ungefähr 40V/µm angelegt wird. In den dickeren Filmen wir eine uneinheitliche Orientierung nach dem tempern beobachtet. Die Lamellen in den Grenzflächen richten sich parallel zur Oberfläche aus und die in der Mitte gelegenen senkrecht zur Oberfläche. Die uneinheitliche Orientierung wird durch Druck instabil und die Lamellen orientieren sich komplett parallel. Die durch Druck verursachte parallele Ausrichtung bleibt stabil solange das angelegte elektrische Feld schwächer als einige zehn V/µm ist. Nur ein Feld von ungefähr 40V/µm kann die uneinheitiche Orientierung stabilisieren. Eine vollständige senkrechte Orientierung wurde in unseren Experimenten nie beobachtet. Diffuse Neutronenstreuung zeigt eine mosaikartige Struktur ohne elektrisches Feld, wobei der Grad der Mosaikartigkeit durch das Drehmoment aufgrund des elektrischen Feldes steigt. Die laterale Korrelationslänge der lamellaren Domänen wird auf 1-2µm geschätzt. Der begrenzte qx-Bereich lässt keine klare Aussage über die Existenz der durch ein elektrisches Feld induzierten strukturellen Schwankungen, die durch die Theorie von Onuki vorhergesagt werden, zu.
Production of saccharogenic and dextrinogenic amylases by Rhizomucor pusillus A 13.36. (2005)

A newly-isolated thermophilic strain of the zygomycete fungus Rhizomucor pusillus 13.36 produced highly active dextrinogenic and saccharogenic enzymes. Cassava pulp was a good alternative substrate for amylase production. Dextrinogenic and saccharogenic amylases exhibited optimum activities at a pH of 4.0-4.5 and 5.0 respectively and at a temperature of 75 degrees C. The enzymes were highly thermostable, with no detectable loss of saccharogenic or dextrinogenic activity after 1 h and 6 h at 60 degrees C, respectively. The saccharogenic activity was inhibited by Ca(2+) while the dextrinogenic was indifferent to this ion. Both activities were inhibited by Fe(2+) and Cu(2+) Hydrolysis of soluble starch by the crude enzyme yielded 66% glucose, 19.5% maltose, 7.7% maltotriose and 6.6% oligosaccharides.

Dispersion flattening in a W fiber (1994)

An exhaustive and simple method for dispersion flattening in double-clad single-mode fibers is presented. The idea is to generate all such fibers with a certain cutoff wavelength and then find, by one-dimensional minimization and direct inspection, fibers yielding minimum dispersion. As examples, the root mean square chromatic dispersion over the wavelength range (1.25, 1.60 µm) is minimized for a W fiber and also for a triangular-index fiber with a depressed inner cladding. The material dispersion is included through a Sellmeier refractive-index formula. The full vector solution of Maxwell's equations is used. It is found, as is well known, that the W fiber is capable of dispersion flattening. The validity of the numerical results presented depends on the validity of the approximate refractive-index model used.

Recent Advances in Casing Wear Technology (1994)

ABSTRACT Casing wear is often a problem in deep wells where doglegs and large tension loads on the drill string combine to produce high lateral loads where the drill string contacts the casing. Casing wear can result in blowouts, lost production, and other hazardous and expensive problems. A mathematical model which describes casing wear in terms of hole geometry, casing/tool-joint material, mud system, and drilling program, has been developed and verified. Over 300 laboratory wear tests have provided wear factors which allow the model to be applied to a wide range of drilling situations. The model has been incorporated into a computer program, CWEAR. The prediction of dogleg severity and casing wear is seriously compromised by directional surveys in which the station spacing is 100 ft or greater. Through the laboratory test program, means to reduce casing wear rate have been demonstrated and applied in the field. Mud lubricants, tool-joint materials, pipe protectors, and casing materials and internal coatings have all been examined as possible means to reduce casing wear. Some mud lubricants significantly reduce frictional drag; others do not. Because a mud lubricant significantly reduces frictional drag does not imply that it will also reduce the casing wear rate. Newer, proprietary tool-joint coating materials have proven effective in reducing casing wear, while continuing to protect the tool joints in open hole. Pipe protectors have proven to be one of the better means of reducing casing wear. Laboratory experiments have demonstrated severe operational difficulties of these protectors. Several of the protector manufacturers are now engaged in development programs to improve their products. Inadequacies in the available methods of measuring casing wear in the field have been demonstrated. As a result of this work, at least two new casing wear measurement tools are under development.

MicroRNA‑146a as a potential regulator involved in the pathogenesis of atopic dermatitis (2019)

Previous studies have demonstrated that microRNA (miR)‑146a is involved in the inflammatory response of atopic dermatitis (AD). The aim of the present study was to investigate the expression of miR‑146a in the serum of patients with AD and in skin lesions of AD animal models. In addition, we aimed to predict and verify the target genes of miR‑146a. miR‑146a expression was measured in AD patient serum via reverse transcription‑quantitative PCR. T‑helper (Th)1 [CD4+; interferon (IFN)‑γ+] and Th2 [CD4+; interleukin (IL)‑4+] expression in peripheral blood mononuclear cells was evaluated using flow cytometry. Following the establishment of a 2,4‑dinitrofluorobenzene‑induced C57BL/6 mouse AD model, Th1 (CD4+IFN‑γ+) and Th2 (CD4+IL‑4+) expression was analyzed in murine spleen cells via flow cytometry. Plasmids were transfected into 293T cells and at 48 h post‑transfection, cells were analyzed using a luciferase assay system. The results revealed that the AD group had a significantly lower Th1/Th2 ratio and a significantly higher miR‑146a expression compared with the control group (P<0.05). Furthermore, a decreased Th1/Th2 ratio and a significantly increased miR‑146a expression were observed in the model group compared with the control group (P<0.01). We also conducted a dual‑luciferase assay to determine whether small ubiquitin‑related modifier 1 (SUMO1) if the target gene of miR‑146a. We observed a ~30% decrease in the relative luciferase activity in cells containing the 3'‑untranslated region of SUMO1 + miR‑146a). The results of the luciferase assay indicated that may be a direct mRNA target of miR‑146a; however, the quantification of band density of SUMO1 expression following western blotting did not significantly differ. The development of animal models in AD research is of vital importance. The results revealed that miR‑146a may be a potential regulator involved in the pathogenesis of AD. Furthermore, the current study determined that miR‑146a could be a valuable marker of AD and thus, may be applied in the development of therapeutic strategies for treating AD.

Production, isolation, and antifungal activity of scytalidin, a metabolite of <i>Scytalidium</i> species (1973)

The production and isolation of scytalidin, a recently reported metabolite of Scytalidium sp., are described. The compound was found to be relatively active in vitro against many fungi associated with stain and decay of pulpwood chips in outside storage and decay in the roots and butts of conifers. Other fungi associated with diseases of trees and deterioration of forest products were also found to be sensitive to scytalidin. Seed germination tests indicated relatively low phytotoxicity.
Natural Course and Prognosis of Intervertebral Disc Diseases (1995)

The disc is an osmotic system that lives from motion. Because of the human sedentary nonmoving lifestyle, disc degeneration is progressive. The morbidity curve does not follow the degeneration curve. In patients between 40 and 50 years old, discs have highlights in their clinical course because of the biomechanical constellation, with the presence of tears and fissures in the anulus and maintained expansion power of nucleus material. In old discs, the nucleus is not willing to move. This is the comfortable rigidity of the aging spine. Not only during lifetime also in case of acute back pain and sciatica natural course is benign. If patients and their doctors wait long enough, most pain curves drop, so that initially planned surgery can be cancelled. This is the waiting list phenomenon. Few patients need a disc operation because of hard disc fragments, which can be identified on magnetic resonance imaging. Open disc surgery is the most frequent and important spine operation. Proper patient selection and good technique with a small approach by microsurgery can help avoid PDS, the worst course and prognosis of intervertebral disc disease.
Classification, identification and subtyping of bacteria based on pyrosequencing and signature matching of 16S rDNA fragments (2002)

The rapid identification of the etiological agent of microbial infections can bring about both clinical and financial benefits. Thus, fast and generally applicable classification methods are needed that will enable us to rapidly distinguish pathogenic bacteria from commensals or saprophytic bacteria found in the same habitat. We here show that provisional classification of bacterial isolates can be performed on a large scale based on 16S rRNA sequence comparisons using Pyrosequencing, a recently described real-time DNA sequence analysis technique, and the concept of signature matching. The probes we have developed, together with the new technology, will enable early diagnosis of specific pathogens, which is critical for the rational use of antimicrobial therapy in clinical medicine.

Influence of Manganese Oxide Minerals on the Formation of Iron Oxides (1988)

Abstract The influence of manganese oxide minerals (cryptomelane, hausmannite, and pyrolusite) on the formation of iron oxides was studied in the FeCl 2 -NH 4 OH system at different Mn/Fe molar ratios (0, 0.01, 0.1, and 1.0) and pHs (3.0, 4.0, 5.0, and 6.0) by X-ray powder diffraction, infrared absorption, transmission electron microscopic, and chemical analyses. In the absence of Mn minerals, lepidocrocite (γ-FeOOH) precipitated at pHs 5.0 and 6.0; however, no precipitate formed at lower pHs. All the Mn minerals studied promoted the precipitation of iron oxides and oxyhydroxides. In the presence of Mn oxides, Fe 2+ was oxidized to Fe 3+ , which hydrolyzed and precipitated as noncrystalline and/or different crystalline iron oxides and oxyhydroxides, depending on the nature of the Mn oxides present in the system. Simultaneously, Mn 2+ was detected in solution after the reaction by electron spin resonance spectroscopy. The presence of cryptomelane and hausmannite resulted in the formation of åkaganeite ( β -FeOOH) and magnetite (Fe 3 O 4 ), respectively. Thus, the effect of Mn oxides on the formation of Fe oxide minerals in the weathering zone merits attention.
Anatomy, histology, and pathology of coronary arteries: A review relevant to new interventional and imaging techniques—Part III (1992)

In the last 15 years, intense interest has focused on various interventional pharmacologic and mechanical forms of therapy for the treatment of atherosclerosis coronary artery disease. Many techniques and devices (dilating balloons, perfusion catheters, thermal probes and balloons, lasers, atherectomy devices, stents, intravascular ultrasound) have been used or are under study for future use. Many of these techniques and devices require an understanding of histologic and pathologic features of the coronary arteries and diseases which affect them. This article reviews selective areas of anatomy, histology, and pathology relevant to the use of various new interventional techniques. Part I of this review will focus on anatomic aspects of the epicardial coronary artery system, coronary arterial distribution, myocardial supply, and histologic features of the normal coronary artery.
Improvement of Charge‐Discharge Characteristics of the Mg‐Ni Powder Electrodes at 55°C (2013)

Magnesium‐nickel (Mg‐Ni) powders are used as the anode materials for secondary lithium (Li) ion batteries. Mg‐Ni powders with ratios of 1 : 1 (Mg : Ni) are prepared and their structure and electrochemical behavior at room temperature and 55°C are investigated. The results show that adding Ni powders to Mg powders can reduce the charge‐discharge capacities and improve cycling life. In charge‐discharge cycle testing at 55°C, the Li ion concentration gradually increased with increasing the duration of electrochemical reactions, indicating that the charge‐discharge capacities increase with increment of cycling number. The formation of a solid electrolyte interface (SEI) layer restrains Mg ions from dissolving into the electrolyte and thus improves the charge‐discharge capacities at high temperature.

Digital Image Scaling (2006)

The proposed scaling algorithm outperforms other standard and widely used scaling techniques. The algorithm uses a mask of maximum four pixels and calculates the final luminosity of each pixel combining two factors; the difference in luminosity between the source pixels. The interpolation is capable of scaling both grey-scaling and color images of any resolution in any scaling factor. Its key characteristics and low complexity make the interpolation very fast and capable of standard tests are presented and compared to other scaling algorithms.
