A new mobile ubiquitous computing application to control obesity: SapoFit (2012)

The objective of this work was the proposal, design, construction and validation of a mobile health system for dietetic monitoring and assessment, called SapoFit. This application may be personalized to keep a daily personal health record of an individual's food intake and daily exercise and to share this with a social network. The initiative is a partnership with SAPO - Portugal Telecom. SapoFit uses Web services architecture, a relatively new model for distributed computing and application integration. SapoFit runs on a range of mobile platforms, and it has been implemented successfully in a range of mobile devices and has been evaluated by over 100 users. Most users strongly agree that SapoFit has an attractive design, the environment is user-friendly and intuitive, and the navigation options are clear.
Terahertz imaging: applications and perspectives (2010)

Terahertz (THz) spectroscopy, and especially THz imaging, holds large potential in the field of nondestructive, contact-free testing. The ongoing advances in the development of THz systems, as well as the appearance of the first related commercial products, indicate that large-scale market introduction of THz systems is rapidly approaching. We review selected industrial applications for THz systems, comprising inline monitoring of compounding processes, plastic weld joint inspection, birefringence analysis of fiber-reinforced components, water distribution monitoring in polymers and plants, as well as quality inspection of food products employing both continuous wave and pulsed THz systems.
Image encryption scheme based on a Gaussian apertured reality-preserving fractional Mellin transform (2020)

An image encryption scheme based on a Gaussian apertured reality-preserving fractional Mellin transform (GARPFrMT) is proposed. The GARPFrMT was realized in the diffraction domain. The Gaussian aperture, like a soft aperture, improved the amount of light that passed through the lens compared to a hard aperture and reduced the light leakage at the edge of the lens, assisting to some extent in resisting direct attacks. In the proposed scheme, the reality-preserving transform was constructed in the diffraction domain to ensure that the cipher-text is real. The GARPFrMT is a nonlinear transformation used for eliminating potential insecurity existing in the linear image encryption system. In order to further enhance the security of the encryption system, an Arnold transform, and a bitwise XOR operation were employed for permutation and scrambling in the encryption process. Simulation results and theoretical analysis show that the proposed algorithm is feasible and capable of withstanding several common attacks.
<b> Resistance mechanisms of <i>Cucumis melo</i> var. <i>agrestis</i> against <i>Trialeurodes vaporariorum</i> and their use to control a closterovirus that causes a yellowing disease of melon </b> (1996)

One of the yellowing diseases that affects melon ( Cucumis melo ) crops cultivated under plastic greenhouses in southern Europe is caused by a closterovirus transmitted by the greenhouse whitefly Trialeurodes vaporariorum . A Cucumis melo var. agrestis accession shows a certain level of resistance to that virus. Under free‐choice conditions, the reproduction of T. vaporariorum on this accession was significantly lower than on the susceptible control accession C. melo cv. ‘Bola de Oro’, and this suggests that T. vaporariorum prefers to colonize other accessions before C. melo var. agrestis . Under no‐choice conditions, we observed that T. vaporariorum reproduction on C. melo var. agrestis was less than on the susceptible controls. The results showed the participation of both antixenosis and antibiosis resistance mechanisms against T. vaporariorum in C. melo var. agrestis . It is difficult to cultivate melon completely free from T. vaporariorum and yellowing disease. However, success in breeding commercial melon cultivars which incorporate the antixenosis and antibiosis found in C. melo var. agrestis together with biological or chemical insect control, or a combination of these, would reduce the insect population and, therefore, the melon‐yellowing disease would occur later and in less severe form.
Analysis of Carnitine Biosynthesis Metabolites in Urine by HPLC–Electrospray Tandem Mass Spectrometry (2002)

HPLC in combination with electrospray ionization tandem mass spectrometry allows rapid determination of urinary carnitine biosynthesis metabolites. Newborns can synthesize carnitine from exogenous N(6)-trimethyllysine, albeit at a low rate.
Self-aligned bend waveguide (SBW) AlGaInP visible laser diode with small beam astigmatism (1993)

The self-aligned bend waveguide (SBW) AlGaInP visible laser developed produces an index guiding waveguide structure by the bend of the double heterolayers and offers a very small beam astigmatism. The laser was fabricated using two-step metalorganic vapor phase epitaxy (MOVPE). Kink-free operation at 40 mW was achieved by modifying the device parameters. The measured beam astigmatism was maintained at less than 1 mu m and did not vary with output power. The aging results under the condition of 50 degrees C and 20 mW output power demonstrated the laser's reliability.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Piezooptical Properties of Si (1998)

The deformation potentials and the piezooptical properties of Si, for strain along the [001] and [111] directions, are investigated with the use of a realistic empirical tight-binding model. The values, as well as their sign, of the deformation potential constants D 1 1 , D 1 5 , D 3 3 , and D 3 5 for the variation of the critical energy E 1 are evaluated for uniaxial and biaxial strain. The sign is found to be negative for D 1 1 , D 3 3 , and D 3 5 , and positive for D 1 5 . The dielectric function of Si under pressure, as well as the reflectivity and the linear piezooptical tensor components P 11 (ω), P 12 (ω) and P 44 (ω) are also evaluated. The main structures in P ij are located around the critical points E 1 and E 2 .
MARKS: Multicast Key Management using Arbitrarily Revealed Key Sequences (1999)

The goal of this work is to separately control individual secure sessions between unlimited pairs of multicast receivers and senders. At the same time, the solution given preserves the scalability of receiver initiated Internet multicast for the data transfer itself. Unlike other multicast key management solutions, there are absolutely no side eects on other receivers when a single receiver joins or leaves a session and no smartcards are required. Solutions are presented for single and for multi-sender multicast. Further, we show how each receiver’s data can be subject to an individual, watermarked audit trail. The cost per receiver-session is typically just one short set-up message exchange with a key manager. Key managers can be replicated without limit because they are only loosely coupled to the senders who can remain oblivious to members being added or removed. The technique is a general solution for access to an arbitrary sub-range of a sequence of information and for its revocation, as long as each session end can be planned at the time each access is requested. It might therefore also be appropriate for virtual private networks or for information distribution on other duplicated media such as DVD.
Cooled Optically Stimulated Luminescence in CaF<sub>2</sub>:Mn (1988)

A new optically stimulated luminescence technique has been developed for the readout of CaF2:Mn thermoluminescent material. Minimum detectable gamma exposures may potentially be measured at 10 nC.kg-1 using the 254 nm line of a mercury lamp. Additional studies were done on CaF2:Mn using 351 nm excimer laser stimulation.
A multi‐centre collaborative study into the treatment of menorrhagia by Nd‐YAG laser ablation of the endometrium (1991)

Endometrial laser ablation would appear to be a popular, safe, effective and economical alternative to hysterectomy for the treatment of menorrhagia.
The unusual methanogenic seryl‐tRNA synthetase recognizes tRNA<sup>Ser</sup> species from all three kingdoms of life (2004)

The methanogenic archaea Methanococcus jannaschii and M. maripaludis contain an atypical seryl-tRNA synthetase (SerRS), which recognizes eukaryotic and bacterial tRNAsSer, in addition to the homologous tRNASer and tRNASec species. The relative flexibility in tRNA recognition displayed by methanogenic SerRSs, shown by aminoacylation and gel mobility shift assays, indicates the conservation of some serine determinants in all three domains. The complex of M. maripaludis SerRS with the homologues tRNASer was isolated by gel filtration chromatography. Complex formation strongly depends on the conformation of tRNA. Therefore, the renaturation conditions for in vitro transcribed tRNASer(GCU) isoacceptor were studied carefully. This tRNA, unlike many other tRNAs, is prone to dimerization, possibly due to several stretches of complementary oligonucleotides within its sequence. Dimerization is facilitated by increased tRNA concentration and can be diminished by fast renaturation in the presence of 5 mm magnesium chloride.
Adaptive Gesture Recognition with Variation Estimation for Interactive Systems (2014)

This article presents a gesture recognition/adaptation system for human--computer interaction applications that goes beyond activity classification and that, as a complement to gesture labeling, characterizes the movement execution. We describe a template-based recognition method that simultaneously aligns the input gesture to the templates using a Sequential Monte Carlo inference technique. Contrary to standard template-based methods based on dynamic programming, such as Dynamic Time Warping, the algorithm has an adaptation process that tracks gesture variation in real time. The method continuously updates, during execution of the gesture, the estimated parameters and recognition results, which offers key advantages for continuous human--machine interaction. The technique is evaluated in several different ways: Recognition and early recognition are evaluated on 2D onscreen pen gestures; adaptation is assessed on synthetic data; and both early recognition and adaptation are evaluated in a user study involving 3D free-space gestures. The method is robust to noise, and successfully adapts to parameter variation. Moreover, it performs recognition as well as or better than nonadapting offline template-based methods.
PUBLIC-KEY TECHNIQUES: RANDOMNESS AND REDUNDANCY (1989)

In December 1984, under reference ISO/TC97/SC20/N42, a Technical Report has been published relating the state-of-the-art of public-key cryptosystems: various comments were sent to WG2, the ISO Working Group dedicated to public-keys; major results have since been published. This document is a brief synthesis on this large subject where randomness and redundancy play the major roles, mainly in integrity techniques: identification, authentication and signature.
Inhibitors of protein-protein interactions (2002)

Protein-protein interactions are the basis of a number of intra- and extracellular processes. One of the challenges facing the pharmaceutical industry in the post genomic era is the rational identification and inhibition of this class of targets. Examples are presented of currently marketed drugs, compounds in clinical development and lead molecules in research programmes, which have been identified as inhibitors of protein-protein interactions. Modern drug discovery tools, including the use of humanised antibodies to validate targets and protein SARs in the identification of lead molecules, have brought these targets within reach.
Molecular Dynamics in Liquids: Spin-Lattice Relaxation of Nitroxide Spin Labels (1994)

Time domain pulsed saturation recovery and electron-electron double resonance spectroscopies were used to measure the spin-lattice relaxation rates of the electron and the nitrogen nucleus in nitroxide spin labels in liquids. The rotational correlation time range covered is from picoseconds to milliseconds. These rates are quantitatively explained by isotropic rotational Brownian dynamics, which modulate the interactions between the electron spin and the molecular angular momentum; the nitrogen and electron spins; and the solvent protons with both the electron and the nitrogen spins. This solves a 20-year-old problem that has limited scientific applications of nitroxides.
Mining Cause-Effect-Chains from Version Histories (2011)

Software reliability is heavily impacted by soft ware changes. How do these changes relate to each other? By analyzing the impacted method definitions and usages, we determine dependencies between changes, resulting in a change genealogy that captures how earlier changes enable and cause later ones. Model checking this genealogy reveals temporal process patterns that encode key features of the software process such as pending development activities: "Whenever class A is changed, its test case is later updated as well." Such patterns can be validated automatically: In an evaluation of four open source histories, our prototype would recommend pending activities with a precision of 60-72%.
The association between urinary kidney injury molecule 1 and urinary cadmium in elderly during long-term, low-dose cadmium exposure: a pilot study (2011)

We showed that urinary kidney injury molecule 1 levels are positively correlated with urinary cadmium concentration in an elderly population after long-term, low-dose exposure to cadmium, while other classical markers do not show an association. Therefore, urinary kidney injury molecule 1 might be considered as a biomarker for early-stage metal-induced kidney injury by cadmium.
Finding fairness in a high volume statutory ADR environment: observations from an Australian workcover conciliation service (2017)

Pre-hearing compulsory Appropriate Dispute Resolution processes (ADR) is increasingly popular in the Australian judicial system, with expectations of achieving fair, quick and efficient resolution of disputes and a reduction in the number of lengthy expensive court based proceedings. While new jurisdictions are enthusiastically incorporating compulsory pre-hearing ADR there is little research on longstanding institutions. The private nature of these court annexed ADR processes can be an inherent weakness; allowing less rigorous use of ADR processes to go unchecked and potentially lessening achievement of substantive justice for individual appellants. In Victoria the Accident Compensation Conciliation Service (ACCS) conciliates all disputes between WorkCover insurers and workers as a compulsory step before proceedings can be taken in court. This paper seeks indicators of how well the ACCS is currently achieving the Workplace Injury Rehabilitation and Compensation Act 2013 (the Act)’s Objectives compared to historical outcomes by examining trends in new applications and resolution rates, and levels of human resources. These statistical trends are derived from 10 consecutive Annual Reports. Key areas explored include power imbalances, work intensification, fairness and selection of assessment criteria. This analysis found resolution rates are slowly declining and workloads are intensifying. Questions remain about how these trends will impact on public confidence in these justice processes and what is meant by ‘reasonable efforts to bring the parties to agreement’. Developing assessment criteria for conciliation processes is identified as a future industry wide project essential for the credibility of mandatory statutory ADR.
Stress-birefringence reduction in elliptical-core fibers under ultraviolet irradiation (1992)

It is found that the temperature sensitivity of a fiber polarimeter can be significantly reduced by UV irradiation of the fiber. A stress-relief model is proposed to explain the mechanism, which is proposed to be a consequence of the breakage of oxygen-deficient bonds (wrong bonds) in the glass network through single-photon or multiphoton absorption, with a subsequent relaxation of the tensile stresses in the fiber core.

A space-time block coding system with backward compatibility for OFDM-based WLANs (2007)

Orthogonal frequency-division multiplexing (OFDM) has been selected as the basis for several standards for high-speed wireless local area networks (WLANs), such as IEEE 802.11a. Increasing the transmission robustness of the SISO (single-input single-output) WLAN system was considered by using the space-time block coding (STBC) scheme with two transmit and one receive antennas. A preamble design for this STBC system was proposed. This preamble is backward compatible with its SISO counterpart as specified by the standards. With this preamble design, a sequential method can be used for the estimation of the channel parameters. Phase tracking and least-squares fitting approaches are discussed to improve channel parameter estimation. A simple soft-detector is also given. Furthermore, a semi-blind channel estimation technique is presented to improve the channel estimation accuracy which leads to improved performance. The approaches given herein are ideally suited for real-time implementations. The effectiveness of this system design and algorithms is demonstrated via numerical examples.
The herpes simplex virus type 1 latency-associated transcript promoter is activated through Ras and Raf by nerve growth factor and sodium butyrate in PC12 cells (1996)

Herpes simplex virus establishes latent infections in the nuclei of sensory neurons. These infections are characterized by the abundant expression of a series of 5' coterminal transcripts termed the latency-associated transcripts (LATs). Available evidence indicates that LAT expression is specifically regulated in latently infected neurons. Although previous studies have examined the regulation of LAT expression in neuronal and nonneuronal cells, the mechanism of regulation of LAT expression in neuronal cells in response to external factors has not been investigated. To address this question, we characterized the activity of LAT promoter fusion constructs in PC12 cells following treatment with nerve growth factor (NGF) and/or sodium butyrate (NaB), agents that affect expression of cell cycle-associated genes. Expression from the LAT promoter was induced 8- to 12-fold by either NGF or NaB alone and 40- to 60-fold when the two agents were added simultaneously. Fibroblast growth factor also induced expression from the LAT promoter but to a lesser extent than NGF. Treatment with factors such as epidermal growth factor, phorbol myristate acetate, cyclic AMP, or KCI had no significant effect on LAT promoter activity. Notably, promoter-reporter constructs containing immediate-early (ICP0 and ICP4), early (ICP8 and UL9), and late (UL10 and UL30) viral promoters were induced only two- to fourfold by NGF, suggesting that the LAT promoter may be unusual among herpes simplex virus genes in the magnitude of its response to this factor. To identify pathways leading to LAT activation in vitro, we characterized the response of the LAT promoter to NGF and/or NaB in PC12-derived cell lines containing mutations in specific signal transduction pathways. We found that activation of the LAT promoter requires Ras activation and that activation of the serine/threonine kinase, Raf, is sufficient to induce LAT expression. Together, these results indicate that the LAT promoter is regulated via the Ras/Raf signal transduction pathway in response to external factors such as NGF and NaB and that LAT expression may be regulated by NGF in latently infected neurons.
Hydrocolloid Gel Particles: Formation, Characterization, and Application (2008)

Hydrocolloid gel particles of micron and sub-micron size are particularly attractive for use in many applications in the food, agricultural, pharmaceutical, and chemical industries, due to their biocompatibility, perception as "natural" materials, and soft-solid texture. Industrial applications for such particles include uses as texturizers in confectionery and cosmetic products, slow-release encapsulation agents for flavors, nutrients, and pharmaceutical products, and thickeners in soups and sauces. Properties such as particle size, hardness, shape, texture, and molecular release rates can be important for individual applications. In addition, product formats will determine specific needs for physical form (e.g. dry or wet) and compatibility with other components. The diverse range of potential applications for hydrocolloid gel particles provide a driver for understanding-led tailoring of raw material and process conditions. This review introduces some of the materials that are used to form hydrocolloid gel particles and the corresponding gel formation mechanisms. One issue of importance in the production of hydrocolloid gel particles is the control of particle properties, such as release profiles, strength, and detectability within products. An alternative technique to traditional methods of hydrocolloid gel particle production is evaluated and a model for control of particle size, and subsequently other particle properties, is proposed. Key properties of hydrocolloid gel particles are identified and characterization methods for evaluating these properties are described.
A UHV guarded Kelvin probe (1972)

A probe for use in measurements of contact potential differences (CPD) has been designed and constructed. The probe has the following unique features: (i) it is guarded against capacitive coupling between the probe and surfaces other than the sample; (ii) it can be heated so that adsorbed gases can be flashed off; (iii) it is excellent for use in UHV systems; (iv) it can be made small enough for nonuniformities in the work function of the sample material to be examined; (v) it is simple to construct. The effectiveness of such a probe to measure true CPD value was tested and the data presented here. Specifically the author is interested in: (i) the contact potential difference against the measured distances between probe and sample; (ii) resolution of the probe (the size of sample area contributing to the observed CPD); (iii) contact potential differences against amplitude of vibration of the probe and against the tilt of the probe about the axis perpendicular to the sample.
