Reduced-complexity synchronization for high-order coded modulations (2015)

This paper focuses on phase noise-impaired communications. An efficient Maximum A-posteriori Probability (MAP) iterative synchronization algorithm, where detection and decoding are performed separately from phase estimation, is proposed. This approach has the following key advantages: (i) its computational complexity is relatively low and its performance is near optimal; (ii) it requires very limited statistical knowledge of the phase noise process; and (iii) it enables the direct use of “off-the-shelf” demodulation and decoding blocks. These features are particularly attractive from the implementation viewpoint, as they lead to the design of effective pragmatic high-order coded modulated schemes. The proposed iterative synchronization and decoding algorithm, evaluated for Low-Density Parity-Check (LDPC)-coded pilot symbol-assisted Quadrature Amplitude Modulation (QAM) schemes, entails a negligible energy efficiency loss with respect to optimized joint decoding and phase estimation approaches, with significantly lower computational complexity.
Localization and Properties of Cell Wall Enzyme Activities Related to the Final Stages of Lignin Biosynthesis (1985)

Cell wall activities which are related to the final stages of lignin biosynthesis, that is the generation of hydrogen peroxide and peroxidase activity, were investigated using biochemical and histochemical methods. Peroxidases involved in both reactions appeared to be restricted to lignifying tissues. Isolated cell walls exhibited a very high affinity for syringaldazine. Cell walls were able, in vitro as well as in vivo, to oxidize guaiacol in the absence of H2O2 when NADH was present in the incubation medium together with p-coumarate and MnCl2 as cofactors. The origin of the NADH used to form H2O2 is discussed.

Integrated external cavity laser (1986)

The fabrication and performance characteristics of single frequency integrated external cavity lasers of the coupled cavity type and the distributed Bragg reflector type are described. The active cavity section of these devices utilizes the double channel planar buried heterostructure scheme for current confinement. The lasers emit near 1.55 μm. The threshold current of these lasers is in the range 70–120 mA. cw linewidth of 7 MHz has been obtained for a 2-mm-long laser at an output power of 3 mW. We believe lasers with longer external cavity should exhibit lower cw linewidths.
Biomarkers of Psychological Stress in Health Disparities Research (2008)

Psychological stress can contribute to health disparities in populations that are confronted with the recurring stress of everyday life. A number of biomarkers have been shown to be affected by psychological stress. These biomarkers include allostatic load, which is a summary measure of the cumulative biological burden of the repeated attempts to adapt to daily stress. Allostatic load includes effects on the hypothalamic-pituitary axis, the sympathetic nervous system and the cardiovascular system. These in turn affect the immune system via bidirectional signaling pathways. Evidence is also building that psychological stress, perhaps via heightened inflammatory states, can increase oxidative stress levels and DNA damage. The inter-relationships of ethnicity, genotype, gene expression and ability to adequately mitigate stress response are just starting to be appreciated. The need to conduct these studies in disadvantaged populations is clear and requires methods to address potential logistical barriers. Biomarkers can help characterize and quantify the biological impact of psychological stress on the etiology of health disparities.
HPS: hybrid profiling support (2005)

Key to understanding and optimizing complex applications is our ability to dynamically monitor executing programs with low overhead and high accuracy. Toward this end, we present HPS, a hybrid profiling support system. HPS employs a hardware/software approach to program sampling that transparently, efficiently, and dynamically samples an executing instruction stream. Our system is an extension and application of dynamic instruction stream editing (DISE), a hardware technique that macro-expands instructions in the pipeline decode stage at runtime. HPS toggles profiling to sample the executing program as required by the profile consumer, e.g. a dynamic optimizer. Our system requires few hardware resources and introduces no "basic" overhead - the execution of instructions that triggers profiling. We use HPS to investigate the tradeoffs between overhead and accuracy of different profile types as well as different profiling schemes. In particular, we empirically evaluate hot data stream, hot call pair, and hot method identification using a number of parameterizations of bursty tracing, a popular sampling scheme used in dynamic optimization systems.
Nuclear inclusions in oculopharyngeal muscular dystrophy consist of poly(A) binding protein 2 aggregates which sequester poly(A) RNA (2000)

Oculopharyngeal muscular dystrophy (OPMD) is an adult-onset disease characterized by progressive eyelid drooping, swallowing difficulties and proximal limb weakness. The autosomal dominant form of the disease is caused by short (GCG)(8-13) expansions in the PABP2 gene. This gene encodes the poly(A) binding protein 2 (PABP2), an abundant nuclear protein that binds with high affinity to nascent poly(A) tails, stimulating their extension and controlling their length. In this work we report that PABP2 is detected in filamentous nuclear inclusions, which are the pathological hallmark of OPMD. Using both immunoelectron microscopy and fluorescence confocal microscopy, the OPMD-specific nuclear inclusions appeared decorated by anti-PABP2 antibodies. In addition, the inclusions were labeled with antibodies directed against ubiquitin and the subunits of the proteasome and contained a form of PABP2 that was more resistant to salt extraction than the protein dispersed in the nucleoplasm. This suggests that the polyalanine expansions in PABP2 induce a misfolding and aggregation of the protein into insoluble inclusions, similarly to events in neurodegenerative diseases caused by CAG/polyglutamine expansions. No significant differences were observed in the steady-state poly(A) tail length in OPMD and normal myoblasts. However, the nuclear inclusions were shown to sequester poly(A) RNA. This raises the possibility that in OPMD the polyalanine expansions in the PABP2 protein may interfere with the cellular traffic of poly(A) RNA.
Use of a Keratolytic Agent With Occlusion for Topical Treatment of Hyperkeratotic Seborrheic Keratoses (2008)

Hyperkeratotic seborrheic keratoses can be satisfactorily managed with topical agents and scraping with reasonable patient satisfaction. Further studies with various keratolytic agents using other delivery systems are warranted.

Handling Continuous Attributes in an Evolutionary Inductive Learner (2005)

This work analyzes experimentally discretization algorithms for handling continuous attributes in evolutionary learning. We consider a learning system that induces a set of rules in a fragment of first-order logic (evolutionary inductive logic programming), and introduce a method where a given discretization algorithm is used to generate initial inequalities, which describe subranges of attributes' values. Mutation operators exploiting information on the class label of the examples (supervised discretization) are used during the learning process for refining inequalities. The evolutionary learning system is used as a platform for testing experimentally four algorithms: two variants of the proposed method, a popular supervised discretization algorithm applied prior to induction, and a discretization method which does not use information on the class labels of the examples (unsupervised discretization). Results of experiments conducted on artificial and real life datasets suggest that the proposed method provides an effective and robust technique for handling continuous attributes by means of inequalities.
Differentiation of F18ab<sup>+</sup>from F18ac<sup>+</sup><i>Escherichia coli</i>by Single-Strand Conformational Polymorphism Analysis of the Major Fimbrial Subunit Gene (<i>fedA</i>) (1998)

Toxin-producing Escherichia coli expressing F18 fimbriae colonizes the small intestines of weaned pigs and causes diarrhea, edema disease, or both. The F18 family is composed of two antigenic variants, F18ab and F18ac. Because many strains do not express F18 fimbriae in vitro, identification and differentiation of these two variants are difficult. Single-strand conformational polymorphism (SSCP) analysis is a rapid method for identifying genetic mutations and polymorphisms. The F18 major fimbrial subunit genes (fedA) of 138 strains were amplified by PCR, and genetic differences were detected by SSCP analysis. The SSCP analysis of the fedA gene differentiated F18ab+ strains from F18ac+ strains. Most strains classified as F18ab+ by SSCP analysis contained Shiga toxin 2e and enterotoxin genes. Most strains classified as F18ac+ by SSCP analysis contained only enterotoxin genes. The SSCP analysis was a useful method for predicting the antigenicity of F18+ E. coli and could also be used for analysis of other virulence genes in E. coli and other pathogenic bacteria.
EEG-Informed Attended Speaker Extraction From Recorded Speech Mixtures With Application in Neuro-Steered Hearing Prostheses (2016)

Current research on AAD always assumes the availability of the clean speech signals, which limits the applicability in real settings. We have extended this research to detect the attended speaker even when only microphone recordings with noisy speech mixtures are available. This is an enabling ingredient for new brain-computer interfaces and effective filtering schemes in neuro-steered hearing prostheses. Here, we provide a first proof of concept for EEG-informed attended speaker extraction and denoising.
Disc Stack Centrifuge Operating Parameters and Their Impact on Yeast Physiology (2008)

Hydrodynamic stresses imposed on brewing cells of Saccharomyces cerevisiae during beer processing can have a detrimental impact on beer quality. The use of centrifuges has become an efficient way to increase brewery throughput as they decrease clarification times and improve fermenter and tank conditioning efficiency. The effect of a disc stack centrifuge on yeast and beer physical stability has been investigated. In this study, a commercial ale yeast strain has been subjected to different operating conditions during centrifugation. Cell viability and intracellular pH decreased due to processing conditions encountered during yeast cropping with a centrifuge. A relationship has been established that yeast cell wall mannan, an unfilterable haze constituent, as a function of G-force and centrifugation cycles, is released from the cell wall while concurrently, particle sizes between 0.5-2.8 μm and beer haze increased. Furthermore, yeast intracellular glycogen and trehalose levels were depleted as a result of centrifugation.
Learning Attribute Representations with Localization for Flexible Fashion Search (2018)

In this paper, we investigate ways of conducting a detailed fashion search using query images and attributes. A credible fashion search platform should be able to (1) find images that share the same attributes as the query image, (2) allow users to manipulate certain attributes, e.g. replace collar attribute from round to v-neck, and (3) handle region-specific attribute manipulations, e.g. replacing the color attribute of the sleeve region without changing the color attribute of other regions. A key challenge to be addressed is that fashion products have multiple attributes and it is important for each of these attributes to have representative features. To address these challenges, we propose the FashionSearchNet which uses a weakly supervised localization method to extract regions of attributes. By doing so, unrelated features can be ignored thus improving the similarity learning. Also, FashionSearchNet incorporates a new procedure that enables region awareness to be able to handle region-specific requests. FashionSearchNet outperforms the most recent fashion search techniques and is shown to be able to carry out different search scenarios using the dynamic queries.
Structural and Functional Characterization of Diffusible Signal Factor Family Quorum-Sensing Signals Produced by Members of the <i>Burkholderia cepacia</i> Complex (2010)

Previous work has shown that Burkholderia cenocepacia produces the diffusible signal factor (DSF) family signal cis-2-dodecenoic acid (C(12):Delta(2), also known as BDSF), which is involved in the regulation of virulence. In this study, we determined whether C(12):Delta(2) production is conserved in other members of the Burkholderia cepacia complex (Bcc) by using a combination of high-performance liquid chromatography, mass spectrometry, and bioassays. Our results show that five Bcc species are capable of producing C(12):Delta(2) as a sole DSF family signal, while four species produce not only C(12):Delta(2) but also a new DSF family signal, which was identified as cis,cis-11-methyldodeca-2,5-dienoic acid (11-Me-C(12):Delta(2,5)). In addition, we demonstrate that the quorum-sensing signal cis-11-methyl-2-dodecenoic acid (11-Me-C(12):Delta(2)), which was originally identified in Xanthomonas campestris supernatants, is produced by Burkholderia multivorans. It is shown that, similar to 11-Me-C(12):Delta(2) and C(12):Delta(2), the newly identified molecule 11-Me-C(12):Delta(2,5) is a potent signal in the regulation of biofilm formation, the production of virulence factors, and the morphological transition of Candida albicans. These data provide evidence that DSF family molecules are highly conserved bacterial cell-cell communication signals that play key roles in the ecology of the organisms that produce them.
Design and Experimentation of WPT Charger for Electric City Car (2015)

Wireless power transfer systems (WPTSs) with inductive coupling are advantageously used to charge the battery pack of electric vehicles. They basically consist of coil coupling, power supply circuitry connected to the transmitting side of the coil coupling, and power-conditioning circuitry connected to the receiving side of the coil coupling. This paper presents the design and implementation of a wireless power transfer (WPT) battery charger for an electric city car. A short overview on the working principles of a series-series resonant WPTS is given before describing in detail the design procedure of the power circuitry needed for its operation, i.e., an alternating-current-direct-current converter cascaded by a high-frequency inverter in the transmitting section and a diode rectifier cascaded by a chopper in the receiving section. The coil coupling with spiral coils is designed with the help of a finite-element-method code. A prototype of the WPT battery charger is built up according to the design results, and experiments that validate the design procedure are carried out.
Seminal cytokine concentrations (IL-1beta, IL-2, IL-6, sR IL-2, sR IL- 6), semen parameters and blood hormonal status in male infertility (1997)

Several lines of evidence indicate that cyokines are involved in male fertility. They are secreted by different parts of the male genital tract and may exert effects on steroidogenesis, spermatogenesis and sperm functions. We measured the concentrations of interleukins (IL-beta, IL-2, IL-6) and those of interleukin soluble receptors (sR IL-2, SR IL-6) in semen of fertile subjects (n = 21) and of patients with a range of andrological diseases (n = 119). The seminal concentrations of cytokines were analysed according to semen parameters as well as to the blood hormonal profiles of follicle stimulating hormone, luteinizing hormone and testosterone. An increase of IL-1beta was observed in the group of patients with infertility. No difference was found between the different subgroups defined on the basis of progressive motility, percentage of abnormal forms and diagnosis of infection. The seminal cytokine concentrations were independent of the blood hormonal status. Our data suggest that the determination of interleukins (-1beta, -2 and -6) or interleukin soluble receptors (sR IL-2, sR IL-6) in human spermatozoa does not provide convenient information in male routine infertility work-up.
Utilization of the wise and cobra 1000/11 technologies for tps transportability and reusable software without software changes or source code availability (2006)

The WISE Technology (WinSoft Instrument System Emulator) allows the reuse of Legacy Test System's software in the Next Generation Testers while preserving the old TPS. The technology supports common programming languages (e.g. ATLAS, HP- BASIC, Fortran, etc.) common communication protocols (GPIB, USB, LXI, etc.) and common instruments (Rack-mount, VXI, PXI, Synthetic Instruments). The COBRA 1000/11 enables replacement of HPI000 and PDP-11 while preserving the old TPS. New TPSs (LabVIEW, C/C++, VB) can be developed and run on the COBRA. There is no change to the legacy software and the source code is not required. A combination of the technologies enables the Next Generation testers to utilize the latest technology available (software and hardware) while still running existing TPS for years to come.
Selected ion flow tube mass spectrometry of urine headspace (1999)

We describe the use of our selected ion flow tube mass spectrometric technique (SIFT-MS) for the analysis of the headspace above urine. Ammonia, nitric oxide, acetone, ethanol and methanol are identified as the dominant species. As expected, the ammonia is increased in the headspace by making the urine alkaline and the nitric oxide is increased by making the urine acidic. Nitric oxide is abnormally high in the headspace of acidified bacterially infected urine and nitrous acid is also detected. The potential clinical implications of analyses of urine by SIFT-MS are alluded to.
Statelessness in Australian Refugee Law: The (Renewed) Case for Complementary Protection (2005)

Australian law currently provides inadequate consideration to the international problem of statelessness. The 1954 Convention relating to the Status of Stateless Persons and the 1961 Convention on the Reduction of Statelessness, Australian laws dealing with this issue are limited and the feature of the inadequacies of the law is the fact that Australia's process for assessing asylum claims has no procedure for considering cases of statelessness.
Identification of Serum Amyloid A as a Biomarker to Distinguish Prostate Cancer Patients with Bone Lesions (2005)

Evaluating Differences in Aluminum Exposure through Parenteral Nutrition in Neonatal Morbidities (2017)

Aluminum is a common contaminant in many components of parenteral nutrition, especially calcium and phosphate additives. Although long-term effects have been described in the literature, short-term effects are not well-known. Currently, the Food and Drug Administration recommends maintaining aluminum at <5 mcg/kg/day. This was a single center, retrospective case-control study of 102 neonatal intensive care unit patients. Patients were included if they had a diagnosis of necrotizing enterocolitis, rickets/osteopenia, or seizures and received at least 14 days of parenteral nutrition. Patients were matched 1:1 with control patients by gestational age and birth weight. Mean total aluminum exposure for the 14 days of parenteral nutrition was calculated using manufacturer label information. Differences in mean aluminum exposure between cases and controls, as well as subgroup analysis in those with renal impairment or cholestasis, was conducted. Aluminum exposure in patients meeting inclusion criteria closely mirrored the aluminum exposure of control patients. The difference in aluminum exposure was not found to be statistically significant, except in patients with cholestasis. Although the study found no difference in aluminum exposure in short-term complications with neonates, long-term complications are well established and may warrant the need to monitor and limit neonatal aluminum exposure.
