Exploiting modern hardware for secure data management (2011)

Databases and data warehouses facilitate the storage and retrieval of large amounts of information. These systems have been increasingly used by corporations to store data such as unit cost information, customers credit card numbers, or patients medical records that are confidential in nature. This trend has been accompanied by numerous incidents of data theft and has resulted in more corporations preferring to store their sensitive records in an encrypted format. Since traditional cryptographic operations entail significant amount of arithmetic calculations, latencies generally arise while recording or retrieving sensitive data. We propose novel and efficient techniques to minimize the cost of cryptographic operations while processing sensitive information. These techniques involve exploiting the parallel computation capability of multi-core CPUs and IO latencies. 
We also present two studies in which we exploit the benefits of a tamper proof cryptographic hardware. In the first study, we discuss how attackers can capture valuable information such as encryption keys from the memories of database systems. We then propose a framework for reducing the disclosure risk of sensitive information for these types of attacks. The experimental results show that the disclosure risk of such attacks can be reduced dramatically while incurring a small performance overhead. 
In the second study, we demonstrate that tamper proof cryptographic hardware can be used for sharing and processing biomedical data. The proposed framework eliminates the need for delegating the storage and processing of sensitive biomedical data to third parties. Within this framework, we define a secure protocol to process genomic data and perform a series of experiments to demonstrate that such an approach can be run in an efficient manner for typical biomedical investigations.
Dynamic power adjustment and resource allocation framework for LTE networks (2016)

In current LTE deployments, the unsupervised and unilateral installation of home or localized base stations, so called eNodeBs, may easily lead to excessive energy consumption and over-provisioning of network infrastructure. In this paper, we propose an energy efficient framework, which dynamically adjusts the power requirements of the system and performs Resource Block (RBs) allocation based on needs. It specifically optimizes power consumption of LTE networks consisting of under-utilized eNodeBs. The Energy Efficiency (EE) issue is formulated as an optimization problem, which trades off EE for SE without adversely impacting the downlink throughput. In order to solve this problem, we develop a heuristic approach called as Two Phase Enhanced Branch and Bound Algorithm (TPEBB) [1]. End-to-end latency, modeled by Markov queues, is used as the main metric for QoS in this study [2]. Finally, we compare the proposed framework with various competing methods to show almost 70% improvement in EE and end-to-end latency.
Supplemental Figure 2. Kaplan-Meier survival curves of Fads1 Null mice. from A New Model to Study the Role of Arachidonic Acid in Colon Cancer Pathophysiology (2023)

&lt;p&gt;Fads1 Null mice exhibited low viability when fed a basal AA-free (10% SAF) diet. Dietary supplementation with AA (0.1, 0.4, 0.6 and 2.0%, w/w) dose-dependently reversed the Fads1 Null mouse phenotype (n=3-5).&lt;/p&gt;
Large deviations of sojourn times in processor sharing queues (2004)

This paper presents a large deviation analysis of the steady-state sojourn time distribution in the GI/G/1 PS queue. Logarithmic estimates are obtained under the assumption of the service time distribution having a light tail, thus supplementing recent results for the heavy-tailed setting. Our proof gives insight into the way a large sojourn time occurs, enabling the construction of an (asymptotically efficient) importance sampling algorithm. Finally our results for PS are compared to a number of other service disciplines, such as FCFS, LCFS, and SRPT.
Non-merohedral twin crystal of 2,3,9,10-tetrakis(triisopropylsilylethynyl)-6,13-bis(trimethylsilylethynyl)pentacene (2007)

All investigated crystals of the title penta­cene derivative, C76H110Si6, obtained from benzene solution and examined at 120 K, were identified as non-merohedral twins. The crystal examined in this study had an approximate 2:1 domain ratio. The mol­ecules have crystallographic inversion symmetry and approximate C2h symmetry, with a planar conjugated central core, including the peripheral C≡C triple bonds. The mol­ecules pack in layers perpendicular to the a axis, with a dihedral angle between individual mol­ecules in adjacent layers of 5.25 (2)°; π–π stacking is prevented by the bulky substituents. One methyl group is disordered over two positions with occupancies of 0.6 and 0.4.
Continuous-Flow Supercritical CO<sub>2</sub> Platform for In-Situ Synthesis and Purification of Small Molecules for Drug Discovery (2023)

The use of supercritical CO2 (scCO2) as an enabling technology paves the way for an efficient in-line integration of the synthesis and purification of organic molecules. The scCO2 platform presented here provides a streamlined process to produce a diverse family of triazoles, common drug precursors, by 1,3-dipolar copper-catalyzed azide-alkyne cycloaddition (CuAAC, Huisgen reaction), also decreasing the environmental impact by significantly reducing the use of traditional solvents. To further exemplify the potential of this scCO2 platform, the synthesis and purification of rufinamide, a drug used to treat seizures associated with Lennox–Gastaut syndrome, is also reported.
Adaptive Arbitrary Pulse Shaper (2008)

A simple, yet effective, ultra wideband pulse shaping circuit architecture is presented. The circuit enables generation of an arbitrary pulse based on in-time superposition of the excitation waveform. The proposed system addresses problems associated with spectrum management, pulse reception and equalization. The pulse shaper was implemented in planar microstrip technology to provide a fully variable waveform.

Room temperature columnar phase: Influence of 2-ethylhexane peripheral chain on the mesomorphism of polyalkynylbenzene-based disc-shaped molecules (2011)

A series of novel symmetrical and non-symmetrical polyalkynylbenzene-based chiral and achiral disc-shaped materials with respectively five and six 2-ethylhexyl peripheral aliphatic chains have been synthesised. The symmetrical and non-symmetrical polyalkynylbenzene was prepared by Sonogashira coupling of hexabromobenzene or monofunctionalised pentabromobenzene with phenylacetylenes substituted by 2-ethylhexyl peripheral chains. The molecular structures were confirmed by spectroscopic and spectrometric analysis. The phenylacetylene bearing 2-ethylhexyl peripheral aliphatic chains via oxygen (OR) or sulfur (SR) or ester (CO2R, without branched chain) functions to balance steric and space-filling effects of the peripheral branched chains. Non-symmetrical molecules exhibit the hexagonal and/or rectangular columnar mesophase whereas symmetrical molecules have higher melting temperature. These molecular engineering drastically affects the intermolecular forces of attractions that lead to unusual molecular self-assembly and affect the transition temperatures. Thus, the mesophase is stabilised above and below room temperature.
Development and evaluation of an enzyme-linked immunosorbent assay for serum Vi antibodies for detection of chronic Salmonella typhi carriers (1987)

An enzyme-linked immunosorbent assay (ELISA) measuring, in serum, immunoglobulin G (IgG), IgM, and IgA to Vi capsular polysaccharide antigen that was tyraminated (Vi-Tyr) to increase its binding efficiency to microtiter plates was compared with the standard passive hemagglutination assay (PHA) as a screening test for chronic Salmonella typhi carriers. Initially, three populations were evaluated: 22 healthy U.S. adults, 17 young Chilean adults with acute typhoid fever, and 51 Chileans who had bacteriologically confirmed S. typhi chronic carriage. IgG-specific Vi-Tyr antibodies were preferentially present in the S. typhi chronic carrier state. A total of 44 of 51 (81%) chronic carriers, 0 of 22 (0%) healthy U.S. adults, and 2 of 17 (12%) Chileans with acute typhoid fever had reciprocal IgG Vi-Tyr ELISA antibody titers in serum of greater than or equal to 200. The IgG Vi-Tyr ELISA was then compared with the PHA as a screening test for chronic carriers in 141 Chilean female food handlers. One woman was serologically incriminated as a carrier by both the IgG ELISA and PHA; her coprocultures were positive for S. typhi. One other woman, identified as a carrier by PHA, was negative by culture and IgG ELISA. The IgG Vi-Tyr ELISA is as sensitive as the PHA (86 versus 76%) and as specific (95 versus 95%) in screening for chronic carriers.
Particle-laden viscous thin-film flows on an incline: experiments compared with an equilibrium theory (2010)

We consider gravity driven flows of particle-laden thin films on an incline. Three distinct regimes are observed depending on the inclination angle and the bulk volume fraction of particles: the particles either settle out of the flow, aggregate at the moving front, or remain well-mixed. The experiments are carried out with a range of particle sizes and fluid viscosities. The results compare well with an equilibrium theory balancing shear-induced migration with settling in the normal direction. We find that the well-mixed regime is transient in nature, with both the particle size and the liquid viscosity a ecting the time scale on which it occurs.
<i>Sarcocystis rommeli</i>, n. sp. (Apicomplexa: Sarcocystidae) from Cattle (<i>Bos taurus</i>) and its Differentiation from <i>Sarcocystis hominis</i> (2015)

Cattle (Bos taurus) are intermediate hosts for three named species of Sarcocystis, S. cruzi, S. hirsuta, and S. hominis. Recently, a fourth species was identified and named S. sinensis. However, S. sinensis originally named a species of Sarcocystis in water buffalo (Bubalus bubalis) in China. Based on unverifiable evidence, it was suggested that the same parasite infects cattle. In addition, S. sinensis was recently declared as nomen nudum because its naming violated the rules of International Code of Zoological Nomenclature. Thus, the fourth species using cattle as an intermediate host does not have a valid name. Here, we propose a new name, Sarcocystis rommeli for the S. sinensis-like parasite from cattle in Argentina, and differentiate it ultrastructurally from S. hominis sarcocysts from experimentally infected cattle. Sarcocystis rommeli sarcocysts were microscopic with a 5-μm-thick wall with slender villar protrusions (Vp); the Vp were up to 5 μm long, up to 0.5 μm wide, and of uneven thickness, often bent at an angle. The ground substance layer (Gs) was up to 0.8 μm thick and smooth. Vesicular structures were seen at the base of the Vp. The bradyzoites were 10-12 μm long. Sarcocystis hominis sarcocysts had Vp that were often upright, up to 7.5 μm long, and up to 1.8 μm wide; the Gs was up to 2 μm thick and without vesicles. Its sarcocyst wall was up to 5.6 μm thick, the vp were bent at an angle, up to 5.8 μm long, the Gs was up to 2 μm thick, but without vesicles seen in S. rommeli. Beef containing sarcocysts of S. rommeli was not orally infectious for two human volunteers and a red fox (Vulpes vulpes). The Sarcocystis described here is molecularly different from S. cruzi, S. hirsuta, and S. hominis based on 18S rRNA and cox1 gene sequences.
High-speed and low-power silicon-organic hybrid modulators for advanced modulation formats (2015)

We demonstrate silicon-organic hybrid (SOH) modulators for generating advanced modulation formats at high data rates and with low energy consumption. SOH integration combines slot waveguides on conventional silicon-on-insulator substrates with highly efficient electro-optic materials. With this approach we generate 16QAM signals at symbol rates of 28 GBd and 40 GBd leading to gross data rates (net data rates) of up to 160 Gbit/s (133 Gbit/s) for a single polarization. This is the highest value achieved by a silicon-based modulator up to now. With a maximum symbol rate of 28 GBd, low drive voltages of only 0.6 V<sub>pp</sub> are sufficient and result in a record-low energy consumption of only 19 fJ/bit. This is the lowest energy consumption that has so far been reported for a 16QAM modulator at 28 GBd.
Aplicação da metodologia TRIZ na inovação do equipamento de teste FRICTORQ (2013)

A TRIZ, acrónimo russo para teoria da resolução de problemas inventivos, é uma metodologia destinada à resolução de problemas, a qual procura criar uma forma sistemática de gerar novas soluções de projeto e de potenciar a criatividade individual. Esta metodologia foi criada e desenvolvida por Genrikh Altshuller nos anos 40 do Séc. XX na extinta União Soviética. Através do estudo de milhares de patentes, Altshuller descobriu que, independentemente da sua área, todas as tecnologias seguem os mesmos princípios e que estes podem ser aplicados na solução de novos problemas. Neste artigo pretende-se demonstrar de que forma a metodologia TRIZ pode ser usada para inovar um equipamento desenvolvido no Departamento de Engenharia Mecânica da Universidade do Minho destinado à medição do coeficiente de atrito em materiais flexíveis (apelidado de FRICTORQ). Através do estudo das leis de evolução para os sistemas tecnológicos descritos nesta metodologia pretende-se ‘prever’ quais os próximos (possíveis) caminhos de evolução deste equipamento e assim permitir a geração de novas ideias que possibilitem conceptualizar outras soluções inovadoras.

The bat influenza H17N10 can be neutralized by broadly-neutralizing monoclonal antibodies and its neuraminidase can facilitate viral egress. (2018)

The diversity of subtypes within the Influenza A virus genus has recently expanded with the identification of H17N10 and H18N11 from bats. In order to further study the tropism and zoonotic potential of these viruses, we have successfully produced lentiviral pseudotypes bearing both H17 and N10. These pseudotypes were shown to be efficiently neutralized by the broadly-neutralizing monoclonal antibodies CR9114 and FI6. Our studies also confirm previous reports that H17 does not use sialic acid as its cellular receptor, as pseudotypes bearing the H17 envelope glycoprotein are released into the cell supernatant in the absence of neuraminidase. However, we demonstrate that N10 facilitates heterosubtypic (H5 and H7) influenza hemagglutinin-bearing pseudotype release in the absence of another source of neuraminidase, significantly increasing luciferase pseudotype production titres. Despite this, N10 shows no activity in the enzyme-linked lectin assay used for traditional sialidases. These findings suggest that this protein plays an important role in viral egress, but is perhaps involved in further accessory roles in the bat influenza lifecycle that are yet to be discovered. Thus we show the lentiviral pseudotype system is a useful research tool, and amenable for investigation of bat influenza tropism, restriction and sero-epidemiology, without the constraints or safety issues with producing a replication-competent virus, to which the human population is naive.
Removal of Selenite from Water Using a Synthetic Dithiolate: An Experimental and Quantum Chemical Investigation (2014)

Combination of the dithiol N,N'-bis(2-mercaptoethyl)isophthalamide, abbreviated as BDTH2 and as 1, with excess H2SeO3 in aqueous acidic (pH ≈ 1) conditions resulted in precipitation of BDT(S-Se-S) (6), with a (77)Se NMR chemical shift of δ = 675 ppm, and oxidized BDT. When the reaction is conducted under basic conditions Se(IV) is reduced to red Se(0) and oxidized 1. No reaction takes place between 1 and selenate (Se(VI)) under acidic or basic conditions. Compound 6 is stable in air but decomposes to red Se(0) and the disulfide BDT(S-S) (9) with heating and in basic solutions. Mechanisms and energetics of the reactions leading to 6 in aqueous solution were unraveled by extensive calculations at the ωB97X-D/aug-cc-pVTZ-PP level of theory. NMR chemical shift calculations with the gauge-independent atomic orbital (GIAO) method for dimethyl sulfoxide as solvent confirm the generation of 6 (calculated δ value = 677 ppm). These results define the conditions and limitations of using 1 for the removal of selenite from wastewaters. Compound 6 is a rare example of a bidentate selenium dithiolate and provides insight into biological selenium toxicity.
Experimental and theoretical investigations on the nature of spontaneous emission to lasing transition in near-unity spontaneous emission factor emitters (2016)

We investigated the lasing criterion for high-β emitters, when the customarily-used intensity jump and linewidth narrowing are no longer trustworthy. Spectrally-resolved photoluminscence and photon autocorrelation are measured from AlAs/GaAs micropillars containing InGaAs quantum dots and analyzed using cavity-QED. A physically intuitive lasing criterion applicable to all lasers is proposed.

Evidence of ancient microbial activity on Mars (2015)

We report for the first time <i>in situ</i> observations of a relatively rare secondary iron arsenate-sulphate mineral named bukovskýite – Fe<sup>3+</sup> <sub>2</sub>(As<sup>5+</sup>O<sub>4</sub>)(S<sup>6+</sup>O<sub>4</sub>)(OH)•7(H<sub>2</sub>O) - found in a shock melt vein of the Tissint Martian meteorite. It is hypothesised that the mineral formed when high concentrations of aqueous H<sup>+</sup>, Fe(III), SO<sub>4</sub> and AsO<sub>4</sub> were maintained for long periods of time in microenvironments created within wet subsurface Martian clays. The aqueous H<sup>+</sup>, Fe(III), SO<sub>4</sub> and AsO<sub>4</sub> species arose from the microbial oxidation of FeS<sub>2</sub> with concurrent release of sequestrated As. The availability of aqueous AsO<sub>4</sub> would also be complemented by dissolution by-products of the microbial reduction of Feoxides influenced by dissolved organic matter that alters the redox state and the complexation of As, thus shifting As partitioning in favour of the solute phase. This hypothesis is substantially supported by SEM analysis of a 15&mu;m spherical structure comprising of a carbonaceous outer coating with a inner core of FeS<sub>2</sub> (pyrite) that showed the pyrite surface with spherical pits, and chains of pits, with morphologies distinct from abiotic alteration features. The pits and channels have a clustered, geometric distribution, typical of microbial activity, and are closely comparable to biologically mediated microstructures created by Fe- and S-oxidising microbes in the laboratory. These microstructures are interpreted as trace fossils resulting from the attachment of bacteria to the pyrite surfaces.
A myeloid tumor suppressor role for <i>NOL3</i> (2017)

Despite the identification of several oncogenic driver mutations leading to constitutive JAK-STAT activation, the cellular and molecular biology of myeloproliferative neoplasms (MPN) remains incompletely understood. Recent discoveries have identified underlying disease-modifying molecular aberrations contributing to disease initiation and progression. Here, we report that deletion of <i>Nol3</i> (<i>Nucleolar protein 3</i>) in mice leads to an MPN resembling primary myelofibrosis (PMF). <i>Nol3<sup>-/-</sup></i> MPN mice harbor an expanded Thy1<sup>+</sup>LSK stem cell population exhibiting increased cell cycling and a myelomonocytic differentiation bias. Molecularly, this phenotype is mediated by <i>Nol3</i><sup>-/-</sup>-induced JAK-STAT activation and downstream activation of <i>cyclin-dependent kinase 6</i> (<i>Cdk6</i>) and <i>Myc</i><i>Nol3<sup>-/-</sup></i> MPN Thy1<sup>+</sup>LSK cells share significant molecular similarities with primary CD34<sup>+</sup> cells from PMF patients. <i>NOL3</i> levels are decreased in CD34<sup>+</sup> cells from PMF patients, and the <i>NOL3</i> locus is deleted in a subset of patients with myeloid malignancies. Our results reveal a novel genetic PMF-like mouse model and identify a tumor suppressor role for <i>NOL3</i> in the pathogenesis of myeloid malignancies.

Relation of type 2 diabetes to individual admixture and candidate gene polymorphisms in the Hispanic American population of San Luis Valley, Colorado (2004)

The prevalence of type 2 diabetes is higher in Hispanic American populations than in populations of European ancestry. The objectives of this study were to distinguish between genetic and environmental explanations for this ethnic difference in disease risk, and to test candidate gene polymorphisms for association with type 2 diabetes in the Hispanic American population of San Luis Valley, Colorado, USA.
