Integration of role based access control with homomorphic cryptosystem for secure and controlled access of data in cloud (2017)

Recent advances in cloud technology facilitates data owners having limited resources to outsource their data and computations to remote servers in Cloud. To protect against unauthorized information access, sensitive data are encrypted before outsourcing. However, traditional cryptosystems need decrypting ciphertext for outsourced computations that may violate data security as well may introduce higher computational complexity. Homomorphic encryption is a solution that allows performing computations directly on ciphertext. On the otherhand, it is evident that the computations on data may vary from users to users depending on the requirements. So, it is not always feasible to allow all computations to different users on the whole ciphertext stored in cloud. In this paper, we proposed a framework for integration of role based access control (RBAC) mechanism with homomorphic cryptosystem for secure and controlled access of data in cloud. Our proposed framework is developed based on trust and role hierarchy with multi-granular operational access rights to heterogeneous stakeholders or users.
Immunologic Overlap of Helper T-Cell Subtypes 17 and 22 in Erythrodermic Psoriasis and Atopic Dermatitis (2015)

This study confirms the TH1- and TH2-skewed phenotype of chronic psoriasis and chronic AD, respectively. However, the immune phenotype, as determined by immunohistochemical analysis, cannot discriminate between these inflammatory diseases in the erythrodermic phase. These findings advance our understanding of the pathophysiological characteristics of erythroderma, psoriasis, and AD and may influence therapeutic decisions.

Virtual histology imaging in acute coronary syndromes: useful or just a research tool? (2010)

Acute coronary syndromes (ACS) frequently cause considerable morbidity and mortality with a high risk of further events within the following year, despite the use of percutaneous coronary intervention (PCI). Numerous studies have described the concept of acute, partial or complete thrombotic occlusion of the coronary artery, which occurs at the site of a friable atherosclerotic plaque with a lipidrich necrotic core and a ruptured overlying thin fibrous cap ("culprit lesion"). Moreover, this process appears independent of the severity of the underlying stenosis. Most of our knowledge about the morphological characteristics of culprit lesions has been obtained from necropsy studies of lesions at the extreme end of the ACS spectrum. The development of intravascular ultrasound (IVUS) with virtual histology (VH), using spectral analysis of the radiofrequency ultrasound backscatter signals to identify the components of atherosclerotic plaque, has allowed in-vivo delineation of the relative contributions of necrotic core and fibrous atheroma in unstable lesions. This evidence suggests that there may be variations in the morphology of plaques that rupture and promote thrombosis in ACS, rather than the traditionally accepted view that a common pathological mechanism is at play. This imaging modality, therefore, provides great potential for invivo information about the culprit lesion. In this review article, we explore the background and potential application of virtual histology to improve the invasive treatment of ACS patients.

Distributional Smoothing with Virtual Adversarial Training (2015)

We propose local distributional smoothness (LDS), a new notion of smoothness for statistical model that can be used as a regularization term to promote the smoothness of the model distribution. We named the LDS based regularization as virtual adversarial training (VAT). The LDS of a model at an input datapoint is defined as the KL-divergence based robustness of the model distribution against local perturbation around the datapoint. VAT resembles adversarial training, but distinguishes itself in that it determines the adversarial direction from the model distribution alone without using the label information, making it applicable to semi-supervised learning. The computational cost for VAT is relatively low. For neural network, the approximated gradient of the LDS can be computed with no more than three pairs of forward and back propagations. When we applied our technique to supervised and semi-supervised learning for the MNIST dataset, it outperformed all the training methods other than the current state of the art method, which is based on a highly advanced generative model. We also applied our method to SVHN and NORB, and confirmed our method's superior performance over the current state of the art semi-supervised method applied to these datasets.
Heterologous Rhizobial Lipochitin Oligosaccharides and Chitin Oligomers Induce Cortical Cell Divisions in Red Clover Roots, Transformed with the Pea Lectin Gene (2000)

Division of cortical cells in roots of leguminous plants is triggered by lipochitin oligosaccharides (LCOs) secreted by the rhizobial microsymbiont. Previously, we have shown that presence of pea lectin in transgenic white clover hairy roots renders these roots susceptible to induction of root nodule formation by pea-specific rhizobia (C. L. Díaz, L. S. Melchers, P. J. J. Hooykaas, B. J. J. Lugtenberg, and J. W. Kijne, Nature 338:579-581, 1989). Here, we report that pea lectin-transformed red clover hairy roots form nodule primordium-like structures after inoculation with pea-, alfalfa-, and Lotus-specific rhizobia, which normally do not nodulate red clover. External application of a broad range of purified LCOs showed all of them to be active in induction of cortical cell divisions and cell expansion in a radial direction, resulting in formation of structures that resemble nodule primordia induced by clover-specific rhizobia. This activity was obvious in about 50% of the red clover plants carrying hairy roots transformed with the pea lectin gene. Also, chitopentaose, chitotetraose, chitotriose, and chitobiose were able to induce cortical cell divisions and cell expansion in a radial direction in transgenic roots, but not in control roots. Sugar-binding activity of pea lectin was essential for its effect. These results show that transformation of red clover roots with pea lectin results in a broadened response of legume root cortical cells to externally applied potentially mitogenic oligochitin signals.
Measuring the van der Waals forces between a Rydberg atom and a metallic surface (1988)

We have observed the deflection of Rydberg atoms towards a metallic surface by the van der Waals force. Cs and Na atoms in states of principal quantum number n were sent between two parallel gold-coated mirrors, spaced by a gap w (2.1 \ensuremath{\mu}m\ensuremath{\le}w\ensuremath{\le}8.5 \ensuremath{\mu}m). We measured the value ${n}_{m}$ at which the transmission cuts off and from the variation of ${n}_{m}$ versus w, we obtained a measure of the atom-surface interaction. For $12<n<30$ this interaction is 3--4 orders of magnitude larger than for ground-state atoms, and it obeys the scaling laws of the Lennard-Jones model.
Development of a Portable Device for Telemonitoring of Snoring and Obstructive Sleep Apnea Syndrome Symptoms (2008)

The First Intensive Balkan Telemedicine and e-Health Seminar was held in the war-ravaged capital of Kosova, Prishtina, in 2002. This event was created under the auspices of the International Virtual e Hospital (IVeH). This organization, the brain child of Rifat Latifi, M.D., was established with the intent to establish a medical capability using telemedicine in an environment where the health infrastructure had been totally destroyed by war. Recently, the IVeH opened six regional telemedicine centers in Kosova. These centers are in the cities of Gjilan, Prizren, Gjakove, Peja, Skenderaj, and Mitrovica. These centers cover the entire country through a telemedicine network. Recently, the Second Intensive Seminar was organized and held October 2123, 2007, in Tirana, Albania. It was organized to broaden the concept of telemedicine and e-health in the Balkans region, and to introduce telemedicine in Albania, which was an ideal choice for holding the seminar. The seminar represented a significant step for Albania as it embraces the concept of telemedicine. These important events have shaped telemedicine development in the Balkans and are serving as a model for the rest of the South Eastern European countries to embrace telemedicine and e-health. This paper summarizes the events of this second seminar and addresses the importance telemedicine has for the region.
The Extracellular Polysaccharide of a Methylotrophic Culture (1978)

The constituent sugars of the extracellular polysaccharide produced by an enrichment culture, growing on methane as sole carbon source, were identified as glucose, galactose, mannose, fucose and rhamnose, in the approximate molar ratios of 1·00: o· 36: 0·19 : O· 31 : 0·16. When the culture was grown on methanol as sole carbon source, only glucose, galactose and mannose, in the approximate molar ratios of 1 ·00 : 0·67 : 0·42, were identified as components of the extracellular polysaccharide.
Identification of 11,13-dihydroxy-14-octadecaenoic acid as a circulating Na+/K+-ATPase inhibitor (1991)

Two digitalis-like compounds (DLC) were purified to homogeneity from bovine plasma. The purification procedure consisted of organic extractions and batch chromatography followed by three subsequent separations using reverse-phase high-performance liquid chromatography. The presence of a DLC in the different fractions was monitored by their ability to inhibit (a) [3H]ouabain binding to rat brain synaptosomes, and (b) microsomal Na+/K(+)-ATPase activity. Using mass spectrometry and nuclear magnetic resonance spectroscopy the structure of one of the DLCs was identified as 11,13-dihydroxy-14-octadecaenoic acid. It is suggested that this new hydroxy, unsaturated, fatty acid derivative may regulate Na+/K(+)-ATPase activity under some physiological and pathological conditions.
Microwave Super-Heated Boiling of Organic Liquids: Origin, Effect and Application (2001)

This paper reports the state of the art of the microwave super-heated boiling phenomenon. When a liquid is heated by microwaves, the temperature increases rapidly to reach a steady temperature while refluxing. It happens that this steady state temperature can be up to 40 K higher than the boiling point of the liquid. With the same reactor, overheating is not observed under conventional heating. The bulk temperature of a microwaved solvent under boiling depends on many factors: physical properties of the solvent, reactor geometry, mass flow, heat flow, and electric field distribution. The influence of these factors is studied and discussed. The kinetics of homogeneous organic reactions shows an extension of Arrhenius behaviour into the super-heated temperature region. Reaction rate enhancement of order 10–100 can thus be achieved, which is normally only possible under pressure. Finally, we present a model predicting reaction kinetics and yields under classical and microwave heating, based on predicted temperature profiles in agreement with experimental data.
<i>Ruscus aculeatus</i> (Butcher's Broom) as a Potential Treatment for Orthostatic Hypotension, with a Case Report (2000)

With proven phlebotherapeutic properties, including vasoconstrictive action and venotonic properties, Ruscus aculeatus shows great promise for ameliorating the symptoms of OH and improving the quality of life for large groups in the population. It clearly deserves to be the object of wider research and study as a treatment for OH.
A new adaptive PID control approach based on closed-loop response recognition (2006)

Abstract:- A new type of adaptive control, based on the closed-loop response recognition is proposed. This approach tries to mimic the behaviour of an expert, who has experience with the particular controlled system. The adaptive system updates the controller parameters according to the changes of system behaviour. The algorithm uses a knowledge-based system, which evaluates the closed-loop response shape after the decay of the transient response or after only a part of it, and computes corrections of controller parameters. Because the main problem of such a control structure consists in designing of the knowledge-base, we focused our interest on the design of an automatic procedure for the knowledge-base generating. Key-Words:- adaptive control, control response shape, recognition, knowledge base generating, PID controller
Shack–Hartmann-based objective straylight assessment of the human eye in an increased scattering angle range (2016)

Objective measurement of straylight in the human eye with a Shack–Hartmann (SH) wavefront aberrometer is limited in imaging angle. We propose a measurement principle and a point spread function (PSF) reconstruction algorithm to overcome this limitation. In our optical setup, a variable stop replaces the stop conventionally used to suppress reflections and scatter in SH aberrometers. We record images with 21 diameters of the stop. From each SH image, the average intensity of the pupil is computed and normalized. The intensities represent integral values of the PSF. We reconstruct the PSF, which is the derivative of the intensities with respect to the visual angle. A modified Stiles Holladay approximation is fitted to the reconstructed PSF, resulting in a straylight parameter. A proof-of-principle study was carried out on eight healthy young volunteers. Scatter filters were positioned in front of the volunteers’ eyes to simulate straylight. The straylight parameter was compared to the C-Quant measurements and the filter values. The PSF parameter shows strong correlation with the density of the filters and a linear relation to the C-Quant straylight parameter. Our measurement and reconstruction techniques allow for objective straylight analysis of visual angles up to 4 deg.
A New Process with the Promise of High J<sub>c</sub> in Oxide Superconductors (1989)

We report a new process which promises high critical current density in oxide superconductors. The process consists of three stages. Firstly a YBa 2 Cu 3 O x sample is rapidly heated and quenched from the Y 2 O 3 plus liquid region. Subsequently the quenched sample is reheated to the Y 2 BaCuO 5 plus liquid region, and then slowly cooled with a temperature gradient in flowing oxygen. The process enables us to grow a superconducting phase unidirectionally and to suppress the second phase intrusion, leading to the production of well textured YBa 2 Cu 3 O x which yields a high J c value in the presence of magnetic fields. It is also found that Bean's critical state is realized in such high J c samples.
Learning Radio Resource Management in RANs: Framework, Opportunities, and Challenges (2018)

In the fifth generation (5G) of mobile broadband systems, radio resource management (RRM) will reach unprecedented levels of complexity. To cope with the ever more sophisticated RRM functionalities and the growing variety of scenarios, while carrying out the prompt decisions required in 5G, this manuscript presents a lean RRM architecture that capitalizes on recent advances in the field of machine learning in combination with the large amount of data readily available in the network from measurements and system observations. The architecture consists of a learner (or a few), which learns RRM policies directly from the data gathered in the network using a single general-purpose learning framework, and a set of distributed actors, which execute RRM policies issued by the learner and repeatedly generate samples of experience. Thus, the complexity of RRM is shifted to the design of the learning framework, while the RRM algorithms derived from this framework are executed in a computationally efficient distributed manner at the radio access nodes. The potential of this approach is verified in a pair of pertinent scenarios, and future directions on applications of machine learning to RRM are discussed. Although we focus on a mobile broadband context, the concepts proposed hereafter extend to any radio access network technology where one can conceive the idea of a central learning unit gathering data from distributed actors.
Robust Servo Control of a High Friction Industrial Turbine Gas Valve by Indirectly Using the Standard$mu$-Synthesis Tools (2006)

The current mu-synthesis tools are not directly suitable for industrial turbine fuel and water control because they lead to high-order controllers with physically meaningless states. The production valve example here is the Woodward GS6 Turbine Gas Metering Valve that has a single-phase permanent magnet motor coupled by a shaft to an inertia disc and a gas metering shoe with a high level of dry (nonlinear) friction and flow forces. The embedded TI-DSP-2407 processor that runs the position controller in the 1 ms loop rate practically limits the maximum controller order to seven. This paper describes how an industrial seventh-order 2-degrees of freedom (DOF) controller was designed by indirectly using the standard tools available in the mu-Toolbox. Step, limit cycle, and frequency response measurements show that the new design compares favorably well with the standard production controller. However, the key advantages were that the first design downloaded into the controller did not require retuning, the design process was higher level, and the measure of "robustness" was in terms of the physical description of plant uncertainties
Highly stereoselective total synthesis of pikronolide, the aglycon of the first macrolide antibiotic pikromycin. Crucial role of benzyl-type protecting groups removable by 2,4-dichloro-5,6-dicyanobenzoquinone oxidation. (1987)

The first total synthesis of pikronolide, the aglycon of pikromycin, isolated as the first macrolide antibiotic, is described. Two segments i (5 : C-1-C-10) and ii (6 : C-11-C-15) were synthesized highly stereoselectively from D-glucose and coupled by Yamaguchi's method to give the ester (17), which was subjected to macrocyclization by means of the intramolecular Wittig-Horner reaction developed by Nicolaou, and the 14-membered cyclic enone (18) was isolated in excellent yield. Removal of protecting groups and Swern oxidation gave pikronolide (2). In this synthesis, 3, 4-dimethoxybenzyl, 4-methoxybenzyl, and benzyl protecting group for hydroxy function played a crucial role.
Clinical evaluation of the serodiagnostic value of enzyme‐linked immunosorbent assay for <i>Rhodococcus equi</i> infection in foals (1997)

An enzyme-linked immunosorbent assay (ELISA) for detection of serum IgG antibodies against Tween 20-extracted antigen of strain ATCC 6939 was applied in Hidaka, Japan to a total of 752 sick foals showing a variety of signs of infectious disease. An optical density (OD) value of more than 0.3 was tentatively fixed to be positive on the basis of readings made of healthy horse sera in previous studies. During a 2 year study, 138 of the 752 sick foals showed an OD value of 0.3 or higher and were designated as 'suspected of R. equi infection'. Age distribution during the initial medical examination of the 138 seropositive foals was significant in that most (64%) foals were age 31-60 days, with a sharp decrease in subjects beyond that age. Of the 138 foals suspected of having R. equi infection, 34 foals (25%) showed OD values of over 0.9 at the initial medical examination, in addition to high blood leucocyte counts and serum fibrinogen and alpha-globulin values. The infectious foals had been treated with antibiotics just before and after serodiagnosis and 126 foals (91%) recovered from the disease. However, no clinical improvement was observed in 12 foals (9%). At necropsy, these foals revealed suppurative pneumonia and lymphadenitis of gut associated lymph nodes accompanied by abdominal abscesses. All isolates from the pulmonary and abdominal abscesses revealed R. equi. These results suggest that OD readings in the high range are associated with severe disseminated infection with R. equi.
Gene expression of the renin-angiotensin system in human tissues. Quantitative analysis by the polymerase chain reaction. (1993)

Activation of tissue-specific gene expression of the components of the renin-angiotensin system (RAS) in humans may play an important role in cardiovascular regulation and pathophysiology. Studies of human tissue RAS expression, however, have been limited by the lack of availability of sufficient amounts of fresh human tissues and a sensitive method for detecting specific mRNAs. To demonstrate the presence of components of local RASs in humans we used the polymerase chain reaction (PCR) after reverse transcription to detect renin- angiotensinogen-, and angiotensin-converting enzyme-mRNA in small quantities of human tissues. Results indicated that all components of the RAS were widely expressed in human organ samples. In order to study changes of gene expression in small tissue samples (e.g., renal biopsies) obtained from patients, we established a competitive PCR assay for quantification of renin, using a 155-basepair deletion mutant of the human renin cDNA as an internal standard. Renin-mRNA concentration was quantitated in the kidney (1.74 +/- 0.2 pg renin/micrograms total RNA), adrenal gland (1.15 +/- 0.15 pg renin/micrograms total RNA), placenta (0.7 +/- 0.1 pg renin/micrograms total RNA), and saphenous vein (0.02 +/- 0.01 pg renin/micrograms total RNA). The method described here may serve as a highly sensitive tool to quantify alterations in gene expression in man under various pathophysiologic conditions. This study should provide the methodological basis for future studies of tissue RAS in human physiology and disease.
