Reduced Precision Checking for a Floating Point Adder (2009)

We present an error detection technique for a floating point adder which uses a checker adder of reduced precision to determine if the result is correct within some error bound. Our analysis establishes a relationship between the width of the checker adder's mantissa and the worst-case magnitude of an undetected error in the primary adder's result. This relationship allows for a tradeoff between error detection capability and area overhead that is not offered by any previously developed floating point adder checking schemes. Experimental results of fault injection experiments are presented which support our analysis.

Significant inhibition by the flavonoid antioxidant silymarin against 12‐O‐tetradecanoylphorbol 13‐acetate–caused modulation of antioxidant and inflammatory enzymes, and cyclooxygenase 2 and interleukin‐1α expression in SENCAR mouse epidermis: Implications in the prevention of stage I tumor promotion (1999)

The flavonoid antioxidant silymarin is used clinically in Europe and Asia for the treatment of liver diseases and is sold in the United States and Europe as a dietary supplement. Recently we showed that silymarin possesses exceptionally high cancer-preventive effects in different mouse skin carcinogenesis models and affords strong anticancer effects in human skin, cervical, prostate, and breast carcinoma cells. More recently, we showed that the anti–tumor-promoting effect of silymarin is primarily targeted against stage I tumor promotion in mouse skin (Cancer Res 1999;59:622–632). Based on this recent study, in this report, further investigations were made to identify and define the biochemical and molecular mechanisms of silymarin's effect during stage I tumor promotion in mouse skin. A single topical application of silymarin at 3-, 6-, and 9-mg doses onto SENCAR mouse skin followed 30 min later with 12-O-tetradecanoylphorbol 13-acetate (TPA) at a 3-μg dose resulted in a 76–95% inhibition (P < 0.001) of TPA-caused skin edema. Similarly, these doses of silymarin also showed 39–90%, 29–85%, and 15–67% protection (P < 0.05 or 0.001), against TPA-caused depletion of epidermal superoxide dismutase, catalase, and glutathione peroxidase activity, respectively. Pretreatment of mice with silymarin also produced highly significant inhibition of TPA-caused induction of epidermal lipid peroxidation (47–66% inhibition, P < 0.001) and myeloperoxidase activity (56–100% inhibition, P < 0.001). In additional studies assessing the effect of silymarin on arachidonic acid metabolism pathways involving lipoxygenase and cyclooxygenase (COX), similar doses of silymarin showed highly significant inhibition of TPA-caused induction of epidermal lipoxygenase (49–77% inhibition, P < 0.001) and COX (35–64% inhibition, P < 0.01 or 0.001) activity. Western immunoblot analysis showed that the observed effect of silymarin on COX activity was due to inhibition of TPA-inducible COX-2 with no change in constitutive COX-1 protein levels. In other studies, silymarin also showed dose-dependent inhibition of TPA-caused induction of epidermal interleukin 1α (IL-1α) protein (39–72% inhibition, P < 0.005 or 0.001) and mRNA expression. Taken together, the results from these biochemical and molecular studies further substantiate our recent observation of silymarin's anti–tumor-promoting effects primarily at stage I tumor promotion. Furthermore, the observed inhibitory effects of silymarin on COX-2 and IL-1α should be further explored to develop preventive strategies against those cancers in which these molecular targets play one of the causative roles, such as non-melanoma skin, colon, and breast cancers in humans.

Parenting payment single: whether member of a couple, whether marriage-like relationship CWTJ and secretary to the DEEWR (2013)

CTWJ was married for a second time in Lebanon after meeting her husband there a few weeks earlier. In 2002 she had a stillborn child. In February 2004, she lodged a claim for parenting payment single (PPS) declaring she had separated from her husband and her first surviving child was born in October2004. CWTJ claimed family tax benefit (FTB) in respect of that child. In April 2007 another child was born and CWTJ claimed FTB for that child.
An immunity-based technique to characterize intrusions in computer networks (2002)

This paper presents a technique inspired by the negative selection mechanism of the immune system that can detect foreign patterns in the complement (nonself) space. In particular, the novel pattern detectors (in the complement space) are evolved using a genetic search, which could differentiate varying degrees of abnormality in network traffic. The paper demonstrates the usefulness of such a technique to detect a wide variety of intrusive activities on networked computers. We also used a positive characterization method based on a nearest-neighbor classification. Experiments are performed using intrusion detection data sets and tested for validation. Some results are reported along with analysis and concluding remarks.
Max-min fair rate control of ABR connections with nonzero MCRs (2002)

Traffic sources that do not have intrinsic temporal characteristics are expected to be transported over ATM networks using the available bit rate (ABR) service. These sources are amenable to reactive flow control and are expected to use bandwidth left over after servicing the guaranteed QoS services (CBR and VBR). Fair allocation of the available bandwidth to competing ABR connections is based on the concept of max-min fairness. The ABR service definition allows sources to specify a minimum cell rate (MCR) that is acceptable to them. Most studies of max-min fair rate allocation assume zero MCRs. In this paper, we first develop a natural extension of the concept of max-min fair rate allocation to the case of ABR sessions with nonzero MCR values. Then we present a centralised algorithm and discuss the construction of distributed algorithms for obtaining the max-min allocation. We show that the max-min allocation can be obtained as the solution of a certain vector equation, and discuss how such a perspective can help in designing stochastic approximation type algorithms for obtaining the max-min allocation when the available capacity is randomly varying.
Oral administration of Lactobacillus paracasei L9 attenuates PM2.5-induced enhancement of airway hyperresponsiveness and allergic airway response in murine model of asthma (2017)

This study investigated allergy immunotherapy potential of Lactobacillus paracasei L9 to prevent or mitigate the particulate matter 2.5 (PM2.5) enhanced pre-existing asthma in mice. Firstly, we used a mouse model of asthma (a 21-day ovalbumin (OVA) sensitization and challenge model) followed by PM2.5 exposure twice on the same day of the last challenge. PM2.5 was collected from the urban area of Beijing and underwent analysis for metals and polycyclic aromatic hydrocarbon contents. The results showed that PM2.5 exposure enhanced airway hyper-responsiveness (AHR) and lead to a mixed Th2/ IL-17 response in asthmatic mice. Secondly, the PM2.5 exposed asthmatic mice were orally administered with L9 (4×107, 4×109 CFU/mouse, day) from the day of first sensitization to the endpoint, for 20 days, to investigate the potential mitigative effect of L9 on asthma. The results showed that L9 ameliorated PM2.5 exposure enhanced AHR with an approximate 50% decrease in total airway resistance response to methacholine (48 mg/ml). L9 also prevented the exacerbated eosinophil and neutrophil infiltration in bronchoalveolar lavage fluid (BALF), and decreased the serum level of total IgE and OVA-specific IgG1 by 0.44-fold and 0.3-fold, respectively. Additionally, cytokine production showed that L9 significantly decreased T-helper cell type 2 (Th2)-related cytokines (IL-4, -5, -13) and elevated levels of Th1 related IFN-γ in BALF. L9 also reduced the level of IL-17A and increased the level of TGF-β. Taken together, these results indicate that L9 may exert the anti-allergic benefit, possibly through rebalancing Th1/Th2 immune response and modulating IL-17 pro-inflammatory immune response. Thus, L9 is a promising candidate for preventing PM exposure enhanced pre-existing asthma.
Posturography and vestibular compensation. (1984)

In unilateral vestibular hypofunction, compensation has to be achieved at the several levels of the balance function. The development of compensation at each level has not necessarily a parallel course. Accordingly, a thorough evaluation of the functional state of the patient, requires a separate assessment for each level. In clinical practice, compensation is evaluated by the testing of provoked vertigo (with eventual positional nystagmus) and by the rotation test results. To these data a measurement of the vestibulospinal level has to be added. Posturography provides this assessment and in this way the global functional state is completed. In many cases the complaints can be objectified and the elaboration of adequate rehabilitation exercises can be founded upon these posturographic data. The detailed analysis of the posturograpohic curves furnishes a diversification of the dysfunctional patterns at this balance level, with also emphasis upon the sensory interaction.
Thermal Conductivity and Microstructure Properties of Porous SiC Ceramic Derived from Silicon Carbide Powder (2013)

Porous SiC ceramic were prepared with silicon carbide powder as the aggregate, silicone resin as the binder and pore agent by the process of mixing, iso-static pressure molding, and calcination. The mechanical properties and microstructures of the samples were characterized with a universal testing machine, X-ray diffraction, scanning electron microscope, and mercury injection. Two main factors, molding pressures and silicone resin mass ratio were studied in the experiments. The thermal conductivity of the samples was tested. The compressive strength was up to 19.4 MPa, and the porosities up to 30%. The thermal conductivities, mainly influenced by porosities, increased from 0.68 W.m-1.K-1 to 1.03 W.m-1.K-1 with the porosity decreasing from 41.96% to 31.30%.
The Mothra tool set (software testing) (2003)

Mothra is a software test environment that supports mutation-based testing of software systems. Mutation analysis is a powerful software testing technique that evaluates the adequacy of test data based on its ability to differentiate between the program under test and its mutants, where mutants are constructed by inserting single, simple errors into the program under test. This evaluation process also provides guidance in the creation of new test cases to provide more adequate testing. Mothra consists of a collection of individual tools, each of which implements a separate, independent function for the testing system. The initial Mothra tool set, for the most part, duplicates functionality existing in previous mutation analysis systems. Current efforts are concentrated on extending this basic tool set to include capabilities previously unavailable to the software testing community. The authors describe Mothra tool set and extensions planned for the future.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

PRIVACYGRID: Supporting Anonymous Location Queries in Mobile Environments (2007)

Abstract : We present PRIVACYGRID - a framework for supporting anonymous location-based queries in mobile information delivery systems. The PRIVACYGRID framework offers three unique capabilities. First, we provide a location privacy preference profile model, called location P3P, which allows mobile users to explicitly define their preferred location privacy requirements in terms of both location hiding measures e.g., location k-anonymity and location and location service quality measures e.g., maximum spatial resolution and maximum temporal resolution. Second, we develop three fast and effective location cloaking algorithms for providing location k-anonymity and location l-diversity in a mobile environment. The Quad Grid cloaking algorithm is fast but has lower anonymization success rate. The dynamic bottom-up or top-down grid cloaking algorithms provide much higher anonymization success rate and yet are efficient in terms of both time complexity and maintenance cost. Finally, we discuss a hybrid approach that combines the top-down and bottom-up search of location cloaking regions to further lower the average anonymization time. In addition, we argue for incorporating temporal cloaking into the location cloaking process to further increase the success rate of location anonymization. We also discuss the PRIVACYGRID mechanisms for anonymous support of range queries. Our experimental evaluation shows that the PRIVACYGRID approach can provide optimal location anonymity as defined by per user location P3P without introducing significant performance penalties.
Reusable Electrochemical Sensing Platform for Highly Sensitive Detection of Small Molecules Based on Structure-Switching Signaling Aptamers (2007)

Aptamers are nucleic acids that have high affinity and selectivity for their target molecules. A target may induce the structure switching from a DNA/DNA duplex to a DNA/target complex. In the present study, a reusable electrochemical sensing platform based on structure-switching signaling aptamers for highly sensitive detection of small molecules is developed using adenosine as a model analyte. A gold electrode is first modified with polytyramine and gold nanoparticles. Then, thiolated capture probe is assembled onto the modified electrode surface via sulfur-gold affinity. Ferrocene (Fc)-labeled aptamer probe, which is designed to hybridize with capture DNA sequence and specifically recognize adenosine, is immobilized on the electrode surface by hybridization reaction. The introduction of adenosine triggers structure switching of the aptamer. As a result, Fc-labeled aptamer probe is forced to dissociate from the sensing interface, resulting in a decrease in redox current. The decrement of peak current is proportional to the amount of adenosine. The present sensing system could provide both a wide linear dynamic range and a low detection limit. In addition, high selectivity, good reproducibility, stability, and reusability are achieved. The recovery test demonstrates the feasibility of the designed sensing system for an adenosine assay.
Expression of the genes for the epidermal growth factor receptor and its ligands in porcine corpora lutea. (1993)

Using reverse transcription-polymerase chain reaction (RT-PCR), transcripts for EGF receptor and for EGF, transforming growth factor-alpha (TGF alpha), amphiregulin (AR) and heparin binding-EGF (HB-EGF) were detected in porcine corpora lutea at day 4, 10 and 20 of the estrous cycle. No cycle-dependent changes were apparent in the expression of the receptor, AR or TGF alpha. In contrast, HB-EGF mRNA levels appeared highest on day 4 during luteal growth and development, whereas EGF mRNA levels appeared highest on day 20 when the corpora lutea undergo luteolysis. These results suggest that luteal function may be subject to regulation by members of the EGF family acting in an autocrine, paracrine or intracrine manner.

Bile Acid Conjugates with Anticancer Activity: Most Recent Research (2020)

The advantages of a treatment modality that combines two or more therapeutic agents in cancer therapy encourages the study of hybrid functional compounds for pharmacological applications. In light of this, we reviewed recent works on hybrid molecules based on bile acids. Due to their biological properties, as well as their different chemical/biochemical reactive moieties, bile acids can be considered very interesting starting molecules for conjugation with natural or synthetic bioactive molecules.
Inter-Stage Gain Error self-calibration of a 31.5fJ 10b 470MS/S Pipelined-SAR ADC (2012)

This paper proposes an Inter-Stage Gain Error (ISGE) calibration method devoted to correct the residue gain errors induced by the parasitic effects, non-ideal op-amp gain and capacitor mismatch, and also the mismatches for supply-derived reference voltages between two stages for Pipelined-SAR ADC. The calibration reuses the SAR ADC to estimate the overall inter-stage gain error and compensates it in the 2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">nd</sup> -stage DAC in 2 cycles, and it is implemented in a Pipelined-SAR which achieves 10b 470 MS/s in 65 nm CMOS with the FoM of 31.5 fJ/conv.-step by consuming only 6% of the total ADC area (0.049 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ).
Superresolution source localization through data-adaptive regularization (2003)

We address the task of source localization using a novel non-parametric data-adaptive approach based on regularized linear inverse problems with sparsity constraints. The class of penalty functions that we use for regularization favors sparsity of the reconstructions, thus producing superb resolution of the sources. We present a computationally efficient technique to carry out the numerical optimization of the resulting cost function. In comparison to conventional source localization methods, the proposed approach provides numerous improvements, including increased resolution, reduced sidelobes, and better robustness properties to noise, limited snapshots, and coherence of the sources. The method is developed for the general source localization scenario, encompassing nearfield and farfield, narrowband and broadband, and non-linear array geometry cases. Simulation results manifest the capabilities of the approach.

Liquid metal expulsion during laser spot welding of 304 stainless steel (2006)

During laser spot welding of many metals and alloys, the peak temperatures on the weld pool surface are very high and often exceed the boiling points of materials. In such situations, the equilibrium pressure on the weld pool surface is higher than the atmospheric pressure and the escaping vapour exerts a large recoil force on the weld pool surface. As a consequence, the molten metal may be expelled from the weld pool surface. The liquid metal expulsion has been examined both experimentally and theoretically for the laser spot welding of 304 stainless steel. The ejected metal droplets were collected on the inner surface of an open ended quartz tube which was mounted perpendicular to the sample surface and co-axial with the laser beam. The size range of the ejected particles was determined by examining the interior surface of the tube after the experiments. The temperature distribution, free surface profile of the weld pool and the initiation time for liquid metal expulsion were computed based on a three-dimensional transient heat transfer and fluid flow model. By comparing the vapour recoil force with the surface tension force at the periphery of the liquid pool, the model predicted whether liquid metal expulsion would take place under different welding conditions. Expulsion of the weld metal was also correlated with the depression of the liquid metal in the middle of the weld pool due to the recoil force of the vapourized material. Higher laser power density and longer pulse duration significantly increased liquid metal expulsion during spot welding.
