M-Cube: A Visualization Tool for Multi-dimensional Multimedia Databases (2011)

The last decade was marked by a striking growth on database size and dimension. This increase is noticeable in many areas, ranging from personal data storage to large corporation databases. The size and high dimensionality of these data sets prompt the application of specialized graphical representations rather than tables and generic charts to visualize the data. This specialization limits the representation to a particular type of database, but ensures a better understanding of its data. In this paper, we present an innovative visualization tool for multi-dimensional multimedia databases, called Multidimensional Cube (or M-Cube). Unlike previous data cubes, which are simple extensions of two-dimensional tables or charts for any type of data, the M-Cube employs a three-dimensional space to visualize multimedia content with great interaction flexibility – the user can change any of the current dimensions by rotation. Our tool is specialized for multimedia contents, that is, text, music, images and videos, allowing the M-Cube to improve both visually and interactively. While the visualization is enhanced by visually rich data elements inside the cube, the interaction provides fast change of dimensions required when exploring multimedia databases.

The described protocol provides an efficient and time-saving tool for the production of osteogenic cells from amniotic fluid that in the future could be used in oral osteointegrated implantology.
Graphene-Based Chemiluminescence Resonance Energy Transfer for Homogeneous Immunoassay (2012)

We report on chemiluminescence resonance energy transfer (CRET) between graphene nanosheets and chemiluminescent donors. In contrast to fluorescence resonance energy transfer, CRET occurs via nonradiative dipole-dipole transfer of energy from a chemiluminescent donor to a suitable acceptor molecule without an external excitation source. We designed a graphene-based CRET platform for homogeneous immunoassay of C-reactive protein (CRP), a key marker for human inflammation and cardiovascular diseases, using a luminol/hydrogen peroxide chemiluminescence (CL) reaction catalyzed by horseradish peroxidase. According to our results, anti-CRP antibody conjugated to graphene nanosheets enabled the capture of CRP at the concentration above 1.6 ng mL(-1). In the CRET platform, graphene played a key role as an energy acceptor, which was more efficient than graphene oxide, while luminol served as a donor to graphene, triggering the CRET phenomenon between luminol and graphene. The graphene-based CRET platform was successfully applied to the detection of CRP in human serum samples in the range observed during acute inflammatory stress.
Femtosecond optical ranging in biological systems (1986)

Optical ranging using femtosecond laser pulses and nonlinear-optical cross correlation is demonstrated for the investigation of the microstructure of biological systems. By using pulses of 65-fsec duration generated by a colliding-pulse mode-locked ring dye laser, a spatial resolution of less than 15 μm is achieved with a detection sensitivity to remitted signals as small as 10−7 of the incident pulse energy. This technique is applied to measure the cornea in rabbit eyes in vivo as well as to investigate the epidermal structure of human skin in vitro.
Osmium(vi) complexes as a new class of potential anti-cancer agents (2011)

A nitridoosmium(VI) complex [Os(VI)(N)(sap)(OH(2))Cl] (H(2)sap = N-salicylidene-2-aminophenol) displays prominent in vitro and in vivo anti-cancer properties, induces S- and G2/M-phase arrest and forms a stable adduct with dianionic 5'-guanosine monophosphate.
Objective Assessment of Region of Interest-Aware Adaptive Multimedia Streaming Quality (2009)

Adaptive multimedia streaming relies on controlled adjustment of content bitrate and consequent video quality variation in order to meet the bandwidth constraints of the communication link used for content delivery to the end-user. The values of the easy to measure network-related Quality of Service metrics have no direct relationship with the way moving images are perceived by the human viewer. Consequently variations in the video stream bitrate are not clearly linked to similar variation in the user perceived quality. This is especially true if some human visual system-based adaptation techniques are employed. As research has shown, there are certain image regions in each frame of a video sequence on which the users are more interested than in the others. This paper presents the Region of Interest-based Adaptive Scheme (ROIAS) which adjusts differently the regions within each frame of the streamed multimedia content based on the user interest in them. ROIAS is presented and discussed in terms of the adjustment algorithms employed and their impact on the human perceived video quality. Comparisons with existing approaches, including a constant quality adaptation scheme across the whole frame area, are performed employing two objective metrics which estimate user perceived video quality.
Subharmonic Analysis for Buck Converters With Constant On-Time Control and Ramp Compensation (2012)

This paper presents a new subharmonic analysis for buck converters with constant on-time control and ramp compensation. For constant on-time control, subharmonic oscillation can be eliminated by adding a compensation ramp with a fixed slope during the off time and a fixed level during the on time. Based on the inductor current information, the compensation ramp, and the charge variations of the output capacitor, the minimum amount of compensation ramp to avoid subharmonic is derived, and the effect of circuit propagation delay is quantified. A prototype of buck converter is built by using constant on-time control with ramp compensation. Experimental results demonstrate the detailed theoretical analysis.
Lipid Metabolism in Fungi (1984)

So far, reviews that have appeared on fungal lipids present data mainly on the lipid composition of these organisms and the influence of lipids on their physiology. These reviews provide little information about the enzymes of lipid metabolism in these organisms and it is assumed, by most workers, that lipid synthesis in all fungi takes place as in Saccharomyces cervesiae, the only fungus in which the complete pathways of phospholipid biosynthesis have been worked out. During the last few years, literature has accumulated on lipid metabolic enzymes of other fungi, as investigators became increasingly interested in this area of research. The present review, after an introduction, will be divided into different sections and each section will deal, comparatively, with various aspects of fungal lipid metabolism and physiology. This review will, therefore, bring out the differences or similarities of lipid metabolism in diverse fungal species.
ADVANCES IN ENERGY FORECASTING MODELS BASED ON ENGINEERING ECONOMICS (2004)

▪ Abstract New energy efficiency policies have been introduced around the world. Historically, most energy models were reasonably equipped to assess the impact of classical policies, such as a subsidy or change in taxation. However, these tools are often insufficient to assess the impact of alternative policy instruments. We evaluate the so-called engineering economic models used to assess future industrial energy use. Engineering economic models include the level of detail commonly needed to model the new types of policies considered. We explore approaches to improve the realism and policy relevance of engineering economic modeling frameworks. We also explore solutions to strengthen the policy usefulness of engineering economic analysis that can be built from a framework of multidisciplinary cooperation. The review discusses the main modeling approaches currently used and evaluates the weaknesses in current models. We focus on the needs to further improve the models. We identify research priorities for the modeling framework, technology representation in models, policy evaluation, and modeling of decision-making behavior.

Enhancing the shopping experience through RFID in an actual retail store (2013)

Radio Frequency Identification (RFID) offers an extraordinary opportunity to enhance the shopping experience of customers in a retail store. There are two types of possible enhancements: increasing the efficiency of traditional processes, or offering new use cases at the store. RFID offers a great opportunity in both cases. RFID can be used to improve the availability of products, reducing stock outs, to streamline the check-out process, reducing the lines, or to substitute the typical Electronic Article Surveillance (EAS) "horse gates" by hidden antennas, freeing the entrance to the store from intimidating barriers. Besides these operational improvements, RFID can also be used to offer shoppers new and enticing functionalities, such as a "magic mirror" to virtually try garments on, or an interactive screen in the fitting room that displays information and offers functionalities related to the particular garments brought in by the customer. This paper describes an actual installation in an apparel retail store in Barcelona, and presents some of the initial conclusions after several months of operation with real customers.
Digital communications using self-phased arrays (2001)

A new technique for full duplex digital communications using adaptive phase conjugation is presented in this paper. The technique is based on mixing the RF signal to an IF where it can be easily processed, and filtering the phase of the IF signal to separate the geometry phase and message phase. The retrodirective array automatically tracks communicating platforms and transmits a directive return signal without the use of phase shifters. A 6-GHz microstrip retrodirective antenna array was built, together with the signal IF processing needed for full duplex operation. The measured RCS values of a linear six-element array are in good agreement with theory and result in a 0- to -5-dB RCS for angles up to /spl plusmn/60/spl deg/. The measured RCS values of a circular array are much flatter and are 0 to -5 dB up to /spl plusmn/80/spl deg/. Two-way digital communications at a baud rate of 78 kb/s was also demonstrated with BER<10/sup -6/ for signal-to-noise ratios around 10 dB. The application areas are in high-performance digital mobile telecommunications for commercial and military applications.
GEOPOLYMER CONCRETE- A REVIEW (2012)

Concrete is the world's most versatile, durable and reliable construction material. Next to water, concrete is the most used material, which required large quantities of Portland Cement. Ordinary Portland Cement production is the second only to the automobile as the major generator of carbon di oxide, which polluted the atmosphere. In addition to that large amount energy was also consumed for the cement production. Hence, it is inevitable to find an alternative material to the existing most expensive, most resource consuming Portland Cement. Geopolymer concrete is an innovative construction material which shall be produced by the chemical action of inorganic molecules. Fly Ash, a by-product of coal obtained from the thermal power plant is plenty available worldwide. Flyash is rich in silica and alumina reacted with alkaline solution produced aluminosilicate gel that acted as the binding material for the concrete. It is an excellent alternative construction material to the existing plain cement concrete. Geopolymer concrete shall be produced without using any amount of ordinary Portland cement. This paper briefly reviews the constituents of geopolymer concrete, its strength and potential applications.
Paths from Pesticides to Parkinson's (2013)

High-quality studies of specific chemical pesticides are needed to determine the relationship between exposure and risk of Parkinson's disease.
An automatic prefetching and caching system (2010)

Steady improvements in storage capacities and CPU clock speeds intensify the performance bottleneck at the I/O subsystem of modern computers. Caching data can efficiently short circuit costly delays associated with disk accesses. Recent studies have shown that disk I/O performance gains provided by a cache buffer do not scale with cache size. Therefore, new algorithms have to be investigated to better utilize cache buffer space. Predictive prefetching and caching solutions have been shown to improve I/O performance in an efficient and scalable manner in simulation experiments. However, most predictive prefetching algorithms have not yet been implemented in real-world storage systems due to two main limitations: first, the existing prefetching solutions are unable to self regulate based on changing I/O workload; second, excessive number of unneeded blocks are prefetched. Combined, these drawbacks make predictive prefetching and caching a less attractive solution than the simple LRU management. To address these problems, in this paper we propose an automatic prefetching and caching system (or APACS for short), which mitigates all of these shortcomings through three unique techniques, namely: (1) dynamic cache partitioning, (2) prefetch pipelining, and (3) prefetch buffer management. APACS dynamically partitions the buffer cache memory, used for prefetched and cached blocks, by automatically changing buffer/cache sizes in accordance to global I/O performance. The adaptive partitioning scheme implemented in APACS optimizes cache hit ratios, which subsequently accelerates application execution speeds. Experimental results obtained from trace-driven simulations show that APACS outperforms the LRU cache management and existing prefetching algorithms by an average of over 50%.
A role for L‐α‐lysophosphatidylinositol and GPR55 in the modulation of migration, orientation and polarization of human breast cancer cells (2010)

LPI and GPR55 play a role in the modulation of migration, orientation and polarization of breast cancer cells in response to the tumour microenvironment.
[Brief intracavitary radiation (137 cesium) of the prostatic site in localized cancer of the prostate: preliminary results after 9 years]. (1989)

Incidental detection of an adenocarcinoma's microscopic focus inside a piece of adenoma or TURP-chips is not rare. Generally, these hidden or "latent" carcinomas without any clinical event, are staged T0 (UICC) or stage A (Whitmore). In reviews, we can find justification of two contrasting attitudes: radical prostatectomy or therapeutic abstention. For the last nine years, we have proposed a third method: endocavitary curietherapy by 137 Cs of prostatic lodge, whose first results, in terms of morbidity and mortality, are discussed.
A New Platelet‐Specific Antigen, Nak<sup>a</sup>, Involved in the Refractoriness of HLA‐Matched Platelet Transfusion (1989)

Serum from a thrombocytopenic patient who was refractory to the transfusions of HLA-matched platelets contained a platelet-specific alloantibody, anti-Naka. Immunofluorescence analyses revealed that the Naka antigen defined by the serum was expressed exclusively on platelets and its distribution was different from P1A1, Baka, Yuka or Yukb. Analysis by Dr. von dem Borne's group revealed the Naka was also different from Koa, Kob or Zwb. Family studies showed that the Naka antigen was inherited as an autosomal codominant trait. Its antigen frequency in the Japanese population was over 97%. The results of the enzyme immunoassay using monoclonal antibodies for antigen immobilization showed that the Naka epitope did not appear to reside on GPIIb/IIIa or Ib. The transfusions of Naka-compatible platelets improved the patient's thrombocytopenia.
Analysis of Feature Point Distributions for Fast Image Mosaicking Algorithms (2010)

In many algorithms the registration of image pairs is done by feature point matching. After the feature detection is performed, all extracted interest points are usually used for the registration process without further feature point distribution analysis. However, in the case of small and sparse sets of feature points of fixed size, suitable for real-time image mosaicking algorithms, a uniform spatial feature distribution across the image becomes relevant. Thus, in this paper we discuss and analyze algorithms which provide different spatial point distributions from a given set of SURF features. The evaluations show that a more uniform spatial distribution of the point matches results in lower image registration errors, and is thus more beneficial for fast image mosaicking algorithms.
Nanopore device-based fingerprinting of RNA oligos and microRNAs enhanced with an Osmium tag (2019)

Protein and solid-state nanopores are used for DNA/RNA sequencing as well as for single molecule analysis. We proposed that selective labeling/tagging may improve base-to-base resolution of nucleic acids via nanopores. We have explored one specific tag, the Osmium tetroxide 2,2'-bipyridine (OsBp), which conjugates to pyrimidines and leaves purines intact. Earlier reports using OsBp-tagged oligodeoxyribonucleotides demonstrated proof-of-principle during unassisted voltage-driven translocation via either alpha-Hemolysin or a solid-state nanopore. Here we extend this work to RNA oligos and a third nanopore by employing the MinION, a commercially available device from Oxford Nanopore Technologies (ONT). Conductance measurements demonstrate that the MinION visibly discriminates oligoriboadenylates with sequence A<sub>15</sub>PyA<sub>15</sub>, where Py is an OsBp-tagged pyrimidine. Such resolution rivals traditional chromatography, suggesting that nanopore devices could be exploited for the characterization of RNA oligos and microRNAs enhanced by selective labeling. The data also reveal marked discrimination between a single pyrimidine and two consecutive pyrimidines in OsBp-tagged A<sub>n</sub>PyA<sub>n</sub> and A<sub>n</sub>PyPyA<sub>n</sub>. This observation leads to the conjecture that the MinION/OsBp platform senses a 2-nucleotide sequence, in contrast to the reported 5-nucleotide sequence with native nucleic acids. Such improvement in sensing, enabled by the presence of OsBp, may enhance base-calling accuracy in enzyme-assisted DNA/RNA sequencing.
Computationally Assisted Discovery and Assignment of a Highly Strained and PANC-1 Selective Alkaloid from Alaska’s Deep Ocean (2019)

We report here the orchestration of molecular ion networking and a set of computationally assisted structural elucidation approaches in the discovery of a new class of pyrroloiminoquinone alkaloids that possess selective bioactivity against pancreatic cancer cell lines. Aleutianamine represents the first in a new class of pyrroloiminoquinone alkaloids possessing a highly strained multibridged ring system, discovered from Latrunculia ( Latrunculia) austini Samaai, Kelly & Gibbons, 2006 (class Demospongiae, order Poecilosclerida, family Latrunculiidae) recovered during a NOAA deep-water exploration of the Aleutian Islands. The molecule was identified with the guidance of mass spectrometry, nuclear magnetic resonance, and molecular ion networking (MoIN) analysis. The structure of aleutianamine was determined using extensive spectroscopic analysis in conjunction with computationally assisted quantifiable structure elucidation tools. Aleutianamine exhibited potent and selective cytotoxicity toward solid tumor cell lines including pancreatic cancer (PANC-1) with an IC<sub>50</sub> of 25 nM and colon cancer (HCT-116) with an IC<sub>50</sub> of 1 μM, and represents a potent and selective candidate for advanced preclinical studies.
Physiological Diagnostic Algorithm Tracks Ventilation and Workload in Patients with Heart Failure (2013)

A physiological diagnostic (PhD) algorithm in a cardiac resynchronization device called Paradym (Paradym CRT+PhD) has a low sensitivity of 34% and a false-positive rate of 2.4 per patient year. This article reports on the results the trial Evaluation of a Diagnostic Feature in a Cardiac Resynchronization Therapy Device [CLEPSYDRA; NCT00957541]. A subanalysis of the study provided the basis for development of an alternative device-derived risk stratifier of heart failure (HF) events, identifying patients likely to develop HF decompensation in the following month with a Hazard Ratio of 4.4 [Gold M et al. EuroPace 2013 (abstr P1511)].
Oblix: An Efficient Oblivious Search Index (2018)

Search indices are fundamental building blocks of many systems, and there is great interest in running them on encrypted data. Unfortunately, many known schemes that enable search queries on encrypted data achieve efficiency at the expense of security, as they reveal access patterns to the encrypted data. In this paper we present Oblix, a search index for encrypted data that is oblivious (provably hides access patterns), is dynamic (supports inserts and deletes), and has good efficiency. Oblix relies on a combination of novel oblivious-access techniques and recent hardware enclave platforms (e.g., Intel SGX). In particular, a key technical contribution is the design and implementation of doubly-oblivious data structures, in which the client's accesses to its internal memory are oblivious, in addition to accesses to its external memory at the server. These algorithms are motivated by hardware enclaves like SGX, which leak access patterns to both internal and external memory. We demonstrate the usefulness of Oblix in several applications: private contact discovery for Signal, private retrieval of public keys for Key Transparency, and searchable encryption that hides access patterns and result sizes.
A presença dos elementos naturais na construção de identidades, memória e História dos lugares: o caso da insularidade e sua abordagem pela literatura. (2001)

"Antes de tudo, é necessário destacar que existe uma variada literatura a respeito das diversas ilhas que existem no mapa mundi e na mente das pessoas. Ou seja, a ilha nem sempre é um lugar no mapa mas, muitas vezes, um lugar na mente. Um lugar onde se imagina encontrar tesouros grandiosos, mulheres sensuais, homens viris, animais exóticos, fontes da juventude, aventuras sem fim ou a paz e o sossego que o ser humano deseja em seus momentos de angústia e cansaço."
Remapping disparate images for coincidence (1993)

With the development of complex multimode computerized microscope systems, it is possible and necessary to obtain images of the same area of the microscopical preparation by several methods of microscopy, such as differential interference contrast, reflection interference microscopy, several wavelengths of fluorescence microscopy, laser scanning and confocal modes. Thus, varied information may be obtained about a single field, in the form of a set of images, taken at different ports of the microscope, using different digitizing cameras, each appropriate to certain tasks. For comparative purposes, the images should be superimposable, pixel by pixel, but in general they are not--they differ in image shape and size, magnification, distortion, centration and orientation. This paper shows how the problem may be approached, using an extension of the remapping procedures described in a previous paper, in which images of a separate grid reference slide are used to detect, quantify and correct the image errors. Affine remapping, without the use of grid images, is also described.
