PrivBasis: Frequent Itemset Mining with Differential Privacy (2012)

The discovery of frequent itemsets can serve valuable economic and research purposes. Releasing discovered frequent itemsets, however, presents privacy challenges. In this paper, we study the problem of how to perform frequent itemset mining on transaction databases while satisfying differential privacy. We propose an approach, called PrivBasis, which leverages a novel notion called basis sets. A theta-basis set has the property that any itemset with frequency higher than theta is a subset of some basis. We introduce algorithms for privately constructing a basis set and then using it to find the most frequent itemsets. Experiments show that our approach greatly outperforms the current state of the art.
The synthesis of single-phase V6O13 and VO2 (1995)

The synthesis of single-phase V6O13 and VO2 is described. The method involves thermal decomposition of NH4VO3 at 0.5 degrees C/min from 50 to 500 degrees C in a specially designed reaction chamber. The synthesis of V6O13 requires a controlled maximum pre
Evidences for Circadian Rhythmicity in the per° Mutant of Drosophila melanogaster (1987)

per0 Mutants of Drosophila melanogaster which are exposed to light-dark cycles (LD) with different Zeitgeber period (T) have a limited range of entrainment. Entrained flies show a characteristic phase relationship of activity to the LD which depends on the period of the driving cycle as expected by oscillator theory. Both facts are taken as evidence that per. possesses endogenous oscillators and that the per gene product is not concerned with central clock structures but rather might be responsible for the mutual coupling between the individual oscillators in a multioscillatory system controlling locomotor activity.

As advancements in computer software continue, Bayesian techniques will become more accessible. Researchers must educate themselves on applications for Bayesian inference, as well as its methods and implications for future research.
[Pathogenesis of hilar cholangiocarcinoma and infection of hepatitis virus]. (2002)

OBJECTIVE To study the correlation between hepatic hilar cholangiocarcinoma and the infection of HB (C)V. METHODS Combined with clinical data, immunohistochemistry was used to detect HBXAg antigen and HCV-C protein in 68 formalin-fixed and paraffin-embedded samples of hilar cholangiocarcinoma. RESULTS Six cases(8.8%) were positive to HBXAg antigen and 24 cases (35.0%) to HCV-C protein respectively. One case was positive to both HBXAg antigen and HCV-C protein. There were statistical differences in differentiation and invasion, lymph node metastasis, treatment between hilar cholangiocarcinomas infected HB(C)V and those non-infected. CONCLUSIONS HBXAg antigen and HCV-C protein may play an important role in the pathogenesis of hilar cholangiocarcinoma. Hilar cholangiocarcinoma infected HB(C)V may have a high malignancy and more poor prognosis.
Transcriptional Regulation of the <i>orf19</i> Gene and the <i>tir-cesT-eae</i> Operon of Enteropathogenic <i>Escherichia coli</i> (2001)

To establish an intimate interaction with the host epithelial cell surface, enteropathogenic Escherichia coli (EPEC) produces Tir, a bacterial protein that upon translocation and insertion into the epithelial cell membrane constitutes the receptor for intimin. The tir gene is encoded by the locus for enterocyte effacement (LEE), where it is flanked upstream by orf19 and downstream by the cesT and eae genes. With the use of a series of cat transcriptional fusions and primer extension analysis, we confirmed that tir, cesT, and eae form the LEE5 operon, which is under the control of a promoter located upstream from tir, and found that the orf19 gene is transcribed as a monocistronic unit. We also demonstrated that the LEE-encoded regulator Ler was required for efficient activation of both the tir and the orf19 promoters and that a sequence motif located between positions -204 and -157 was needed for the Ler-dependent activation of the tir operon. Sequence elements located between positions -204 and -97 were determined to be required for the differential negative modulatory effects exerted by unknown regulatory factors under specific growth conditions. Upon deletion of the upstream sequences, the tir promoter was fully active even in the absence of Ler, indicating that tir expression is subject to a repression mechanism that is counteracted by this regulatory protein. However, its full activation was still repressed by growth in rich medium or at 25 degrees C, suggesting that negative regulation also occurs at or downstream of the promoter. Expression of orf19, but not of the tir operon, became Ler independent in an hns mutant strain, suggesting that Ler overcomes the repression exerted by H-NS (histone-like nucleoid structuring protein) on this gene.
Optimizing the internal quantum efficiency of GaInN SQW structures for green light emitters (2006)

Abstract Ga x In 1–x N/GaN single quantum well (QW) structures emitting in the range of 450 nm to 620 nm have been grown by MOVPE. Temperature and excitation power dependent photoluminescence (PL) was used to determine the internal quantum efficiency (IQE) for these structures. For the blue emitting QWs high IQE values on the order of 60% were achieved. Due to a reduced growth temperature, reduced growth rate and increased V/III ratio we obtained QWs with good morphology and high In content above 25%. Thinner QWs with high In content showed a clear improvement of IQE compared to QW‐structures with larger thickness but smaller In‐content emitting at the same wavelength. Between λ peak = 460 nm and 530 nm we observed a slight reduction in IQE with values of 58% at 490 nm and 40% at 525 nm. But towards λ peak = 620 nm IQE decreased due to the electric field induced separation of the electron and hole wavefunction down to 1%. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Magnetic films and optics in computer memories (1967)

The thermal cycle-time and read bandwidth are calculated for a magnetic film memory which is written by heating from focussed light and read by the same beam at reduced power. The heat flow model approximates the memory bit as a planar disc source and the cycle time <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</tex> is determined by the condition that, for repetitive writing, the ratio of transient to dc temperature must be >1. Then it is found that the bit radius <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">a</tex> must be <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">< \sqrt{kT}</tex> = thermal diffusion length in time <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</tex> ( <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</tex> = thermal diffussivity of substrate); for <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T < 1\mu</tex> s and an Ag substrate this gives <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">a \sim 5 \mu</tex> . For a magneto-optical reflection coefficient <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k \sim 10^{-3}</tex> the shot-noise limited bandwidth is then found to be ∼100 MHz for a temperature rise of 10 degrees in the memory bit. Surface noise due to imperfections will limit the bandwidth to less than the shot-noise limit unless some form of signal processing can be used to extract the magnetic information. For incident light polarized at, say, 45° to the plane of incidence, phase modulation of one of the components will generate a magneto-optical signal with a phase of 0 or π relative to the modulation, depending on the magnetic state of the memory bit. Additional topics which are considered include a review of magneto-optical enhancement using multilayer dielectric films, a discussion of possible memory materials, and a proposal for a content-addressed memory which is interrogated magneto-optically.

線上遊戲中個人對遊戲規則的詮釋與再建構:以台灣玩家「開外掛」之行為為例 (2007)

This thesis discussed about the “Open outside-suspending” phenomenon, which violates the rules, of Taiwanese online-game players. Two theories were used as the basis of the research. First, the magic circle proposed by Huizinga defines the conception of games. And the following interpretation, asserted by Salen & Zimmerman , divides the players by ideal and practical rules. Based on the above ideas, this research observed how the “Open outside-suspending” players interpret, deconstruct, and reconstruct the rules that established in the on-line game community. With the use of semi-structure one-to-one interviewing technique, the investigation included 25 online game players. From these interviewers’ own experiences and views on outside-suspending, the study aimed to analyze their conceptions of rules as well as the processes of constructing, deconstructing, and reconstructing during their playing. Based on a general idea, those classifying themselves as “manual players” form an extremely opposing group to the outside-suspending. However, the research findings showed that such groupings, manual and outside-suspending, are not the case. In reality, according to the players’ external behaviors, they should be divided into three groups, the manual, semi-automatic, and fully automatic ones. What’s more, the so-called manual players are actually rare. In most of these players’ real experiences, most of them are at the different levels of semi- and fully automatic who often deconstruct the rules in their own ways. Meanwhile, by observing the “open outside-suspending” phenomenon through Huizinga, Salen & Zimmermnan’s point of views, it showed that the imagination of “Magic Circle” in the fictitious world was not a shared concept. Conversely, the players make the boundary between real life and fictitious game individually by their own special online and offline contexts. Besides, due to the influence of these intricately interwoven threads between reality (life) and fabrication (games), each player tends to use their unique methods to construct the rules from the ideal principles to personal ones. As a result, these individuals’ schemata in online and offline societies led them to the different interpretations toward the community of “Magic Circle”.
Sickle Cell Disease: Basic Principles and Clinical Practice (1994)

Written by 80 of the world's foremost basic scientists and clinicians, this volume is the first comprehensive reference on sickle cell disease. Because this disease has diverse manifestations and involves many medical specialties, the contributors were chosen for their expertise in specific areas. Their discussions cover virtually every aspect of the disease - its molecular and cellular biology, pathophysiology, diagnosis, organ-specific complications, and clinical management. Coverage begins with recent laboratory findings on sickle hemoglobin and sickle red cell pathology. Subsequent sections examine the pathophysiology and natural history of sickle cell disease and describe diagnostic methods, including prenatal diagnosis and neonatal Screening. A major section focuses on strategies for management of the organ-specific complications and psychosocial aspects of the disease. Coverage of therapy includes antibiotics, transfusion, surgery, patient control, nursing concerns, and future prospects for cure of the disease by gene therapy, bone marrow transplantation, and drugs that induce fetal haemoglobin synthesis.
Cryo-Electron Microscopy of Aura Viruses (1998)

Abstract Alphaviruses are a group of enveloped viruses in the Togaviridae family. Studies of several alphaviruses, including Ross River, Sindbis and Semliki Forest viruses, by cryo-electron microscopy (cryo-EM), three-dimensional (3D) image resconstruction and other techniques have illustrated that these spherical viruses have a T=4, multi-layered structure. Aura virus, which is closely related to Sindbis, was first isolated in South America. Unlike the other alphaviruses, both genomic RNA (12kb, 49S) and subgenomic RNA(4.2kb, 26S) are encapsidated efficiently and form mature virions. Studies on negatively-stained virus particles demonstrated that there are two major size classes. The first contains particles of ∼72nm diameter, which are most similar to wild type virus, whereas the second class includes particles of ∼62nm in diameter. The 72nm particles are believed to have one copy of genomic RNA or one to three copies of subgenomic RNA, and a T=4 structure. The 62nm particles probably only have a single copy of subgenomic RNA and are presumed to be T=3 structures.

Model reduction of interconnected linear systems (2008)

Abstract The problem of model reduction of linear systems with certain interconnection structure is considered in this paper. To preserve the interconnection structure between subsystems in the reduction, special care needs to be taken. This problem is important and timely because of the recent focus on complex networked systems in control engineering. Two different model reduction methods are introduced and compared in this paper. Both methods are extensions to the well‐known balanced truncation method. Compared with earlier work in the area these methods use a more general linear fractional transformation framework, and utilize linear matrix inequalities. Furthermore, new approximation error bounds that reduce to classical bounds in special cases are derived. The so‐called structured Hankel singular values are used in the methods, and indicate how important states in the subsystems are with respect to a chosen input–output map for the entire interconnected system. It is shown how these structured Hankel singular values can be used to select an approximation order. Finally, the two methods are applied to a model of a mechanical device.

Direct observation of complexes formed between recA protein and a fluorescent single-stranded deoxyribonucleic acid derivative (1982)

The reaction of chloroacetaldehyde with single-stranded DNA (ssDNA) yields epsilon DNA, a highly fluorescent substance. The binding of recA protein to epsilon DNA nearly doubles its fluorescence yield. The enhanced fluorescence signals the formation of a recA-epsilon DNA complex. This complex exhibits an ATPase activity as great as that of the corresponding recA-ssDNA complex. Addition of a saturating concentration of adenosine 5'-O-(3-thiotriphosphate) (ATP gamma S) to a solution of the recA-epsilon DNA complex yields a further rise in fluorescence. Saturation with ATP produces the same rise. The nucleotide triphosphates have converted the recA-epsilon DNA complex into the respective ATP gamma S-recA-epsilon DNA and ATP-recA-epsilon DNA complexes. The fluorescence changes that accompany the formation of the three complexes have enabled us to (1) establish by titration that recA protein binds to 6.0 +/- 0.3 nucleotides of epsilon DNA, (2) show that the binding of ATP to the recA-epsilon DNA complex is highly cooperative under various conditions, with a Hill coefficient of 2.4-4.9 and Kapp = 25 +/- 2 micro M, (3) show that the binding of ATP gamma S is also highly cooperative, with a Hill coefficient of 3.3-4.2 and Kapp congruent to 0.5 micro M, and (4) perform initial measurements on the rate at which recA protein transfers between polynucleotides. The experiments provide the first direct observation of an ATP-recA-ssDNA-like complex, and they illuminate some of the properties of such complexes.
New Health Delivery Networks: Merging Public Health and Health Care Systems (2013)

Incomplete coordination between medical care and public health delivery systems can result in significant missed opportunities for improving population health and constraining overall resource use. This lecture uses insight from the field of public health services and systems research (PHSSR) to examine: (1) why medical care and public health systems often fail to connect; (2) what are the potential health and economic consequences of these failures; and (3) what are the opportunities for connecting medical care and public health delivery to improve population health.
Fast range imaging by CMOS sensor array through multiple double short time integration (MDSI) (2002)

The presented novel approach for direct range image acquisition is based on a CMOS image sensor with extremely short integration time and a defined flash illumination by fast infrared laser diodes. Determining the light propagation time by the MDSI method on a chip, a single CMOS sensor chip measures simultaneously distances to a net of numerous target points in a few milliseconds with a resolution of typically 5 mm. The exclusive use of semiconductor components assures high robustness, small size and low cost under high volume production. Hence the fields of applications are very versatile, ranging from safety and security to transportation, traffic and industrial automation as well.
Rules: Looking in the Right Place (1989)

I read ′The Philosophy of Wittgenstein′, Rush Rhees′s review of Pitcher′s study of Wittgenstein, soon after it was published, and have read it again many times since then. Phrases and sentences in it have stuck in my mind, and have guided my thought about Wittgenstein′s work. Some of Rhees′s remarks stayed in my mind because I understood them, or thought I did, and found them particularly illuminating; some because I did not understand them, or not at all completely, but had a persistent sense that I should try to. Rhees also drew attention in that review to several passages in Wittgenstein′s writings and to remarks of his in lectures; and his selection of those passages and remarks has always seemed to me one of the best things in the review. I shall look at the first half of the sentence of Rhees′s with which I began this essay. But I want first simply to list some of the things in that review, things which have been in my mind for years and which I am particularly glad to have had put there.

Finite Element Modeling of Tires on Snow2 (2006)

Abstract Vehicle movement on unpaved surfaces is important to military, agriculture, forestry, mining, construction, and recreation industries. Because of the complicated nature of vehicle-terrain interaction, comprehensive modeling of off-road mobility is often done using empirical algorithms. The desire to incorporate more physics into performance models has generated great interest in applying numerical modeling techniques in a full three-dimensional analysis, accounting for the deformation of both the tire and the terrain. In this study, a three-dimensional finite element model was constructed to simulate a tire rolling over snow. The snow was modeled as an inelastic material using critical-state constitutive modeling and plasticity theory. The snow material model was generated from experiments on the mechanical deformation of snow and was validated using a plate sinkage test. The tire models represent a range of sizes accommodating light-truck and off-road military vehicles and were rolled on snow of various depths. The combined tire-terrain models were validated using force measurements collected with instrumented vehicles and with measured snow deformation. The model results were also compared to vehicle mobility predictions made using the winter algorithms of the NATO Reference Mobility Model. These comparisons illustrate the agreement between the finite element models and field measurements of motion resistance forces and snow deformation under the tire.
Fabrication and Properties of Porous SiC-Cordierite Ceramics (2013)

The porous SiC-cordierite ceramics were prepared from SiC, calcined kaolin, talc, aluminum hydroxide, and graphite as pore-forming. The influence of pore-forming agent contents and sintering temperatures on the porosity and flexural strength of porous SiC-cordierite ceramics were investigated. The grain phases and the fracture surface micrograph were analyzed with XRD and SEM, respectively. The results show that the sample sintered at 1350°C for 3h with 15% graphite as the pore-forming agent exhibits the most excellent properties: flexural strength of 63.74MPa was achieved at a porosity of 31.80%.
