Properties of oxidized porous silicon as insulator material for RF applications (2005)

In this paper we present a method for developing thick layers of silicon oxide. This work is divided into two parts. First we present the fabrication of the dielectric layer using porous silicon technology. In the second part we show the characterization of coplanar transmission lines deposited on it. In order to form the oxide layer, an electrochemical etching in hydrofluoric acid is used to form microporous silicon. Next, several oxidations steps are used to oxidize the porous silicon (OPS) until the final thick oxide layer is obtained. In order to characterize the oxide layer simple coplanar lines were fabricated. Material parameters were extracted from scattering parameters measured with a network analyzer. Experimental results of oxidized porous silicon layer show good properties and can be used as a thick dielectric material, taking the place to other fabrication methods as flame hydrolysis deposition (FHD) and chemical vapor deposition (CVD) techniques.
Branch specificity of bovine colostrum CMP-sialic acid: N-acetyllactosaminide alpha 2—-6-sialyltransferase. Interaction with biantennary oligosaccharides and glycopeptides of N-glycosylproteins. (1985)

By use of 500-MHz 1H NMR spectroscopy, the branch specificity of bovine colostrum CMP-NeuAc:Gal beta 1----4GlcNAc-R alpha 2----6-sialyltransferase towards a biantennary glycopeptide and oligosaccharides of the N-acetyllactosamine type, differing in completeness and structure of their core portion, was investigated. In agreement with earlier reports (Van den Eijnden, D. H., Joziasse, D. H., Dorland, L., Van Halbeek H., Vliegenthart, J. F. G., and Schmid, K. (1980) Biochem. Biophys. Res. Commun. 92, 839-845), it appears that the enzyme strongly prefers the galactosyl residue at the Man alpha 1----3Man branch of the biantennary glycopeptide for attachment of the first sialic acid residue. This branch specificity is fully preserved with the structure (formula; see text) Reduction of the reducing N-acetylglucosaminyl residue in this structure, however, leads to a decreased branch specificity, whereas removal of this residue results in a random attachment of sialic acid to the galactoses at both branches. The decrease in branch specificity is accompanied by a reduction in the rate of sialic acid transfer to the galactose at the alpha 1----3 branch. Our results indicate that the presence of the aforementioned N-acetylglucosaminyl residue is a minimal structural requirement for branch specificity of the sialyltransferase. We propose that in the interaction of the sialyltransferase with its substrates, this N-acetylglucosaminyl residue functions as a recognition site mediating the correct positioning of the substrate on the enzyme.

Bean Abscission Cellulase (1988)

The physiology and anatomy of abscission has been studied in considerable detail; however, information on the regulation of gene expression in abscission has been limited because of a lack of probes for specific genes. We have identified and sequenced a 595 nucleotide bean (Phaseolus vulgaris cv Red Kidney) abscission cellulase cDNA clone (pBACl). The bean cellulase cDNA has extensive nucleic and amino acid sequence identity with the avocado cellulase cDNA pAV363. The 2.0 kilobase bean mRNA complementary to pBACl codes for a polypeptide of approximately 51 kilodalton (shown by hybrid-selection followed by in vitro translation). Bean cellulase antiserum is shown to immunoprecipitate a 51 kilodalton polypeptide from the in vitro translation products of abscission zone poly(A)(+) RNA. Ethylene initiates bean leaf abscission and tissue-specific expression of cellulase mRNA. If ethylene treatment of bean explants was discontinued after 31 h and then 2,5-norbornadiene given to inhibit responses resulting from endogenously synthesized ethylene, polysomal cellulase mRNA hybridizing to pBACl decreased. Thus, ethylene is required not only to initiate abscission and cellulase gene expression but also to maintain continued accumulation of cellulase mRNA. Explants treated with auxin 4 hours prior to a 48 hour treatment with ethylene showed no substantial accumulation of RNA hybridizing to pBACl or expression of cellulase activity.
A Study on the Internet Defamation Policy and Law - Focusing on the Communications Decency Act of 1996 and the Brodie Case (2012)

Defamation is one of most frequently occurring daily legal violation because it can easily be done by words. In internet generation with flooding internet forum websites and social network services, internet defamation is becoming one of most serious problems in many leading IT countries including Korea and United States. Being such a critical issue that can lead to a suicide, Korean policy makers has undertaken efforts to prevent internet defamation by defining liabilities of internet users and internet service providers. Many of policies and laws including the Telecommunication Information Usage Promotion and Security Protection Act of 2007 are modeled after that of United States. Thus, study aims to explore American defamation law and internet defamation law analyzing the Communications Decency Act of 1996 and a recently decided precedent, Brodie case, in Maryland state court.
A national survey of athletic trainer roles and responsibilities in the allied clinical setting. (1992)

Data collected from a survey instrument mailed to all 188 NATA-approved allied clinical setting directors were analyzed to assess the current levels of professional preparation as related to the NATA competencies, job roles, and responsibilities of certified athletic trainers in the allied clinical setting. The topics examined included specific roles and responsibilities of certified athletic trainers currently employed in an allied clinical setting. A response rate of 70.5% was obtained. Skills and services provided by the clinical ATC rated as very important were: evaluation, prevention, and rehabilitation/reconditioning of athletic injuries. Competency regarding recognition and evaluation received the highest relative importance score, which is consistent with the findings of the 1982 NATA Role Delineation Study and the 1991 NATA Validation Study. Educational preparation through NATA-approved curriculums had the highest importance in professional preparation for a career in athletic training. The data indicated that educational emphasis for athletic training students interested in employment in the nontraditional setting has diverged from the guidelines established in the 1982 Role Delineation Study. The results of this study suggest that students preparing for a career in a nontraditional (clinical) setting should focus on developing skills in athletic injury evaluation, rehabilitation and reconditioning, and prevention. While these results support findings of the 1982 Role Delineation Study, additional research is needed to address the levels of professional preparation as related to the NATA competencies, job roles, and responsibilities of the clinical athletic trainer.
Design of a uniplanar resonance phase-matched Josephson traveling-wave parametric amplifier (2017)

In this paper, we present the design of a resonance phase-matched Josephson travelling-wave parametric amplifier that have a 12 GHz 3 dB-bandwidth centred near 10 GHz. Our design utilises a unilateral planar circuit structure which requires only a single layer of thin superconductor film deposited on a supporting substrate to reduce the fabrication complexity. The nonlinear medium of the device is provided by a series of Josephson junctions embedded in a coplanar waveguide with integrated shunt capacitor, and the dispersion of the transmission line is controlled by quarter wavelength resonators coupled capacitively to the feedline. Here, we describe in detail the electromagnetic designs of the various components of the amplifier, and the coupled-mode equations model that governs the three-wave mixing process. We extract the required circuit parameters of the amplifier through electromagnetic modelling, and determine the parametric gain-bandwidth product of the amplifier using an analytical model. Finally, we discuss the various design aspects that affect the overall performance of the amplifier.
An Optimal Message Authentication Scheme for Lossy Channels (2006)

This paper presents an optimal chaining technique for message authentication in lossy environments such as MANets. The scheme is similar in topology to star chaining but is more economic in terms of transmission and computational overhead. The overhead is independent of group size and it enables individual packet verification, so it is ideal for selective multicast transmission, video and audio streaming. The generality of the scheme makes it suitable for many scenarios. A security vulnerability of the proposed scheme has been identified that limits the usefulness of this scheme in certain scenarios. Furthermore, we have pointed out a conceptual mistake by Sato et. al. in constructing a comparison table (F. Sato, et al., 2005)
Cardiac Electrophysiological Effects of Pinacidil and Related Pyridylcyanoguanidines (1988)

It has been suggested that certain direct acting vasodilators increase potassium conductance (gK) of smooth muscle membranes. A similar increase of gK in cardiac tissue would be expected to selectively shorten the action potential duration (APD). The present studies were conducted to determine whether a series of pyridylcyanoguanidine antihypertensive agents, including pinacidil, might shorten the APD of canine Purkinje fibers and ventricular muscle, and if so, whether this effect can be correlated with their antihypertensive activities in anesthetized spontaneously hypertensive rats (SHR). Cardiac Purkinje fiber APD was decreased by most compounds. P-1075, the most potent compound of the series (EC50 = 3.7 x 10(-8) M), reduced the APD of Purkinje fibers by a maximum of 91 +/- 2% at 10(-6) M with no change in the maximum rate of rise (Vmax) or conduction time of the action potential. Similar selective effects on APD were noted in ventricular muscle cells. Shortening of APD was not altered by muscarinic blockade with atropine (3 x 10(-6) M) or adenosine receptor blockade with isobutyl methylxanthine (3 x 10(-5) M). In chloralose-anesthetized SHR, the pyridylcyanoguanidines reduced mean arterial blood pressure (BP) and left ventricular dP/dtmax with an order of potency similar to their effect on APD95. The most potent compound was again P-1075 with an ED50 of 8 micrograms/kg i.v. for its effect on BP. When the ED50 for BP reduction in vivo was compared with the EC50 for Purkinje fiber APD shortening in vitro, an excellent correlation was obtained (r = 0.97, p less than 0.005).(ABSTRACT TRUNCATED AT 250 WORDS)

Stacked Similarity-Aware Autoencoders (2017)

As one of the most popular unsupervised learning approaches, the autoencoder aims at transforming the inputs to the outputs with the least discrepancy. The conventional autoencoder and most of its variants only consider the one-to-one reconstruction, which ignores the intrinsic structure of the data and may lead to overfitting. In order to preserve the latent geometric information in the data, we propose the stacked similarity-aware autoencoders. To train each single autoencoder, we first obtain the pseudo class label of each sample by clustering the input features. Then the hidden codes of those samples sharing the same category label will be required to satisfy an additional similarity constraint. Specifically, the similarity constraint is implemented based on an extension of the recently proposed center loss. With this joint supervision of the autoencoder reconstruction error and the center loss, the learned feature representations not only can reconstruct the original data, but also preserve the geometric structure of the data. Furthermore, a stacked framework is introduced to boost the representation capacity. The experimental results on several benchmark datasets show the remarkable performance improvement of the proposed algorithm compared with other autoencoder based approaches.
Abnormalities in Serum Lipids and Liver Fuction in Nigeria Patients with Leprosy (2001)

To estimate the serum lipids and liver function of Nigerian leprosy patients and the effect of dietary habits on their serum lipid levels. A questionnaire was administered to all leprosy patients seen in leprosy clinics in Anambra State to ascertain disease type, activity and duration as well as dietary preferences. Each patient was medically examined and venous blood sample obtained for the determination of total cholesterol, triglycerides, albumin, total globulin and tests for liver function. The analysis of variance was applied for the comparison of data obtained for the groups of patients in the leprosy spectrum and the different disease activity. The t-test was used to compare the data obtained for the defined dietary habits. P TgBL>Tg-TT. There were functional abnormalities in the liver of patients with lepromatous leprosy. The differences in the liverfunction and the serum proteins between the leprosy groups were significant (P Jnl of Medical Investigation and Practice Vol.2 2001: 5-10
Analysis on the Interaction and Integration of Piano Education and Moral Education in Colleges and Universities (2015)

With the reform of China’s educational system going deeper, quality-oriented education has been fully implemented and enforced. Simultaneously, education principles and personnel training objectives in colleges and universities have changed a lot.

Piano education is an important part of the education system in colleges and universities. Under the new situation, ideological and moral education focuses on the improvement of the internal quality of students. It has inevitability with the development of the times as they fuse organically, and that can greatly improve the quality of teaching, makes the students’ physical and mental health development toward a more positive direction. Accordingly, the article started with the current situation of the cultivation of talents in colleges and universities, analyzes and discusses the interaction and fusion of piano education and moral education.
Immunogenicity Studies of Cosmetically Administered Nonanimal-Stabilized Hyaluronic Acid Particles (2007)

BACKGROUND Hypersensitivity resulting from humoral or cellular immunologic mechanisms is the least well-documented of adverse events associated with dermal fillers. OBJECTIVE Humoral and cellular immunogenicity of nonanimal-stabilized hyaluronic acid (NASHA) was studied in prospective clinical trials involving nasolabial fold augmentation. METHODS In two randomized clinical studies, 150 (10 centers) and 283 (17 centers) subjects received NASHA as Restylane and/or Perlane (both QMed, Uppsala, Sweden; mean, 69 mg) for dermal augumentation. Serum immunoglobulin (Ig)E and IgG anti-NASHA were measured by immunoassay at 0, 6, and 24 weeks and IgE anti-NASHA by intradermal skin testing (ID-ST) at 0 and 24 weeks. The 24-week ID-ST site was biopsied 3 days later for histopathologic evidence of cell-mediated immunity. RESULTS Of 433 subjects, 42 systemic adverse experiences were reported by 37 participants; all but 1 were judged by investigators to be unrelated to NASHA administration. All ID-STs and IgE anti-NASHA results were negative, indicating no IgE sensitization. Serologically, 91.8% of 425 subjects were negative for IgG anti-NASHA (<1.5 μg/mL) at all time points, whereas 7.8% had positive enrollment IgG anti-NASHA (range, 1.5–18.5 μg/mL) that remained essentially unchanged over the study period. The 24-week ID-ST biopsies showed no histological evidence for NASHA-induced cell mediated lymphocytic inflammatory reactions (Type IV hypersensitivity) or superficial dermal edema (Type 1 hypersensitivity). CONCLUSION NASHA administration does not elicit clinical/laboratory evidence for cellular or humoral immune responses in 98% of individuals, supporting the conclusion that Restylane and/or Perlane are not commonly immunogenic or allergenic.
Four Diseases, Two Associations, One Patient: A Case of Frontal Fibrosing Alopecia, Lichen Planus Pigmentosus, Acne Rosacea, and Morbihan Disease. (2018)

A 77-year-old woman born in the Dominican Republic presented with fullness of the glabella and medial eyebrows for 1 year followed by alopecia of the lateral eyebrows and frontal hairline. She stated that although she had a high hairline at baseline, it had receded in the past year. She had also noted central scalp hair thinning that started 6 years earlier. She denied all styling practices that used traction or chemical processes, although she admitted to hair dye and blow dryer use. She reported "acne" in the central face for decades and darkening of the skin on the lateral face for several years. Her medical history included hypertension, hyperlipidemia, hypothyroidism, benign paroxysmal positional vertigo, and treated breast ductal hyperplasia. Her medications were metoprolol, amlodipine, aspirin, levothyroxine, omeprazole, pravastatin, and meclizine; she denied starting any new medications within the past 2 years. Her family history was notable for androgenic pattern alopecia in a brother and a high hairline in her father. Review of systems was negative except for knee arthralgias and seasonal allergic rhinitis.
High spatial resolution diffusion tensor imaging and its applications. (2002)

Introduction Magnetic Resonance Imaging is at present the only imaging technique available to measure diffusion of water and metabolites in humans. It provides vital insights to brain connectivity and has proved to be an important tool in diagnosis and therapy planning in many neurological diseases such as brain tumour, ischaemia and multiple sclerosis. This project focuses on the development of a high resolution diffusion tensor imaging technique. In this thesis, the basic theory of diffusion tensor MR Imaging is presented. The technical challenges encountered during development of these techniques will be discussed, with proposed solutions. New sequences with high spatial resolution have been developed and the results are compared with the standard technique more commonly used. Overview The project aims at the development of diffusion tensor imaging techniques with a high spatial resolution. Chapter 2 will describe the basic physics of MRI, the phenomenon of diffusion and the measurement of diffusion by MRI. The basic parameters used all through the projects will be presented. In Chapter 3, a reproducibility study on DTI with the single shot EPI sequence will be conducted. The single shot DT-EPI was carried out on a stroke patient. In Chapter 4, current techniques on high spatial resolution DTI will be explored. Sequences of Interleaved EPI of two segments and EPI with Half Fourier acquisition will be developed. The sources of artefacts which contaminate most DT images will be discussed with solution proposed. Chapter 5 proposed a new selective averaging algorithm for the data acquired by the sequences of interleaved EPI. It does not require cardiac gating during data acquisition period and thus increase the speed of data collection. A new ghost free segmented EPI sequence will be presented in Chapter 6: Half-FOV EPI. The technique will be tested on a phantom in vitro as well as in two normal male volunteers in vivo. A comparison study on diffusion tensor imag

Systematic evaluation of rating scales for impairment and disability in Parkinson's disease (2002)

We assessed the clinometric characteristics of rating scales used for the evaluation of motor impairment and disability of patients with Parkinson's disease (PD), conducting a systematic review of PD rating scales published from 1960 to the present. Thirty studies describing clinometrics of 11 rating scales used for PD were identified. Outcome measures included validity (including factor structure), reliability (internal consistency, inter-rater, and intrarater) and responsiveness. We traced three impairment scales (Webster, Columbia University Rating Scale [CURS] and Parkinson's Disease Impairment Scale), four disability scales (Schwab and England, Northwestern University Disability Scale [NUDS], Intermediate Scale for Assessment of PD, and Extensive Disability Scale), and four scales evaluating both impairment and disability (New York University, University of California Los Angeles, Unified Parkinson's Disease Rating Scale [UPDRS], and Short Parkinson Evaluation Scale). The scales showed large differences in the extent of representation of items related to signs considered responsive to dopaminergic treatment or to those signs that appear late in the disease course and lack responsiveness to treatment. Regardless of the scale, there was a conspicuous lack of consistency concerning inter-rater reliability of bradykinesia, tremor, and rigidity. Overall disability items displayed moderate to good inter-rater reliability. The available evidence shows that CURS, NUDS, and UPDRS have moderate to good reliability and validity. In contrast to their widespread clinical use for assessment of impairment and disability in PD, the majority of the rating scales have either not been subjected to an extensive clinometric evaluation or have demonstrated clinometric shortcomings. The CURS, NUDS, and UPDRS are the most evaluated, valid, and reliable scales currently available.
