Symbolic Analyses of Dataflow Graphs (2017)

The synchronous dataflow model of computation is widely used to design embedded stream-processing applications under strict quality-of-service requirements (e.g., buffering size, throughput, input-output latency). The required analyses can either be performed at compile time (for design space exploration) or at runtime (for resource management and reconfigurable systems). However, these analyses have an exponential time complexity, which may cause a huge runtime overhead or make design space exploration unacceptably slow. In this article, we argue that symbolic analyses are more appropriate since they express the system performance as a function of parameters (i.e., input and output rates, execution times). Such functions can be quickly evaluated for each different configuration or checked with respect to different quality-of-service requirements. We provide symbolic analyses for computing the maximal throughput of acyclic synchronous dataflow graphs, the minimum required buffers for which as soon as possible (ASAP) scheduling achieves this throughput, and finally, the corresponding input-output latency of the graph. The article first investigates these problems for a single parametric edge. The results are extended to general acyclic graphs using linear approximation techniques. We assess the proposed analyses experimentally on both synthetic and real benchmarks.
Three-dimensional graphene-based hierarchically porous carbon composites prepared by a dual-template strategy for capacitive deionization (2013)

A three-dimensional graphene-based hierarchically porous carbon (3DGHPC) has been prepared by a dual-template strategy and explored as the electrode for capacitive deionization (CDI). The texture analyses indicate that the incorporation of porous carbon into the three-dimensional graphene (3DG) has constructed a hierarchical pore network with a bimodal pore distribution. Compared to those of the 3DG (250.3 m2 g−1, 0.49 cm3 g−1), the 3DGHPC exhibits a higher specific surface area of 384.4 m2 g−1 and an improved pore volume of 0.73 cm3 g−1. The electrosorption behavior investigated by electrochemical techniques demonstrates that the 3DGHPC electrode displays superiority in specific capacitance and cyclability, as well as electrical conductivity. The CDI performance evaluated by batch mode experiments at a direct voltage of 1.2 V in a 25 mg L−1 NaCl aqueous solution reveals that the 3DGHPC electrode presents a higher electrosorptive capacity of 6.18 mg g−1 and an increased desalination efficiency of 88.96%. The enhanced deionization properties are deduced to arise from the improved specific surface area and increased pore volume, as well as an elevated electrical conductivity.
AP2 Gene Determines the Identity of Perianth Organs in Flowers of Arabidopsis thaliana. (1989)

We have examined the floral morphology and ontogeny of three mutants of Arabidopsis thaliana, Ap2-5, Ap2-6, and Ap2-7, that exhibit homeotic changes of the perianth organs because of single recessive mutations in the AP2 gene. Homeotic conversions observed are: sepals to carpels in all three mutants, petals to stamens in Ap2-5, and petals to carpels in Ap2-6. Our analysis of these mutants suggests that the AP2 gene is required early in floral development to direct primordia of the first and second whorls to develop as perianth rather than as reproductive organs. In addition, our results support one of the two conflicting hypotheses concerning the structures of the calyx and the gynoecium in the Brassicaceae.

New frontiers in capsule endoscopy (2007)

Capsule endoscopy (CE) was launched at the beginning of this millennium and has since become a well-established tool for evaluating the entire small bowel for manifold pathologies. CE far exceeded our early expectations by providing us with a tool to establish the correct diagnosis for elusive gastrointestinal (GI) conditions such as obscure GI bleeding, Crohn's disease, polyposis syndrome, and others. Recent evidence has shown CE to be superior to other imaging modalities, such as small bowel follow-through X-ray, colonoscopy with ileoscopy, computerized tomographic enterography, magnetic resonance enteroclysis, and push enteroscopy, for diagnosing small bowel pathologies. Gastroenterologists would prefer the convenience of a single capsule that can create images of the area from the oral cavity to the anal canal in one 'shot'. Because of anatomic and physiologic differences in the GI tract, however, it may not be possible to use the same capsule and so we would need a different one for each organ. In addition to the pioneer small bowel capsule, there is now an esophageal capsule, and a colonoscopy capsule will soon be available. The ideal CE should be capable of performing a biopsy or carrying out an online analysis (an 'optical' biopsy) and 'stop' bleeding by an epinephrine injection, a heat probe, argon plasma coagulation, etc. The ultimate capsule would include special detectors for white blood cells, and it would check oncological markers (e.g. CEA, CA 19-9), perform serology tests (e.g. antiendomysial, IgE), and measure various cytokines, pH levels, temperature and pressure, as well as deliver drugs. The capsule's motility feature in the small bowel may open a window to study the pathophysiology of relatively elusive medical entities, such as irritable bowel syndrome. The optimal capsule needs to contain an automatic computerized system for automatic detection of pathologies, such as that present in the ECG-Holter recording, in order to overcome the drawback of time-consuming viewing. Our dream is that endoscopists will be able to 'control and steer' the CE, as they are able to do in standard endoscopy. This would mean being able to maintain the capsule steady in a selected area and hold the view in order to have more time to examine the opposite wall of the bowel. In conclusion, future gastroenterologists will have a number of CEs from which to choose, according to the purpose of the evaluation, whether it be diagnostic and/or therapeutic. Just as the idea of a swallowed capsule taking images as it travels along the human anatomy was once in the realm of sheer fantasy, we have every reason to believe that the ultimate CE will become a reality in the not far distant future.
<title>A Two Layer Photoresist Process In A Production Environment</title> (1983)

A manufacturable, high resolution photoresist process is described. This process was developed to increase production margins on the 1.0 μm geometries used in the Hewlett Packard NMOS III process: This was accomplished through a modification of the portable conformal mask (PCM) technique,2 which drastically reduced substrate effects on GCA. wafer stepper performance by the introduction of a bleachable dye in the bottom photoresist layer.
Steroid Replacement in Addison's Disease and in Subjects Adrenalectomized for Cushing's Disease: Comparison of Various Glucocorticoids* (1982)

The efficacies of four different glucocorticoids as replacement therapy in Addison's disease or after adrenalectomy for Cushing's disease were compared by assessment of plasma ACTH and free plasma glucocorticoid levels determined by a radioreceptor assay (RRA). Twelve patients were maintained on 9α-fluorocortisol (0.05–0.1 mg/day) and received cortisone acetate (25 mg at 0800 h; 12.5 mg at 2000 h) on day 1, hydrocortisone hemisuccinate (20 mg at 0800 h; 10 mg at 2000 h) on day 2, dexamethasone (0.5 mg at 0800 h; 0.5 mg at 2000 h) on day 3, 9α-fluorocortisol alone on day 4, and prednisolone (5 mg at 0800 h; 2.5 mg at 2000 h) on day 5 of study. Plasma glucocorticoid levels after cortisone acetate, hydrocortisone, or prednisolone treatment reached peak values 1 h after administration, as measured by RRA; for all three steroids, levels were significantly below normal by 0800 h the next morning. In contrast, glucocorticoid levels, measured by RRA, attained peak levels 2 h after dexamethasone treatment, with a much more sustained action; levels were still normal at 0800 h on the following day. One of the 12 patients had Nelson's syndrome, with ACTH levels approximately 15,000 pg/ml, which suppressed incompletely with all steroids. Four patients on long term replacement therapy had undetectably low levels of ACTH even 36 h after glucocorticoid withdrawal. In the remaining 7 patients, there was a marked difference between dexamethasone and the other steroids in terms of ACTH suppression. For equivalent plasma glucocorticoid RRA activity, dexamethasone appeared 35–50 times as potent as hydrocortisone in terms of suppressing ACTH. We conclude 1) that dexamethasone appears to achieve effective control of ACTH secretion in hypoadrenal patients with normally responsive ACTH at the lowest total glucocorticoid dose, as judged by RRA; and 2) that prolonged glucocorticoid replacement therapy, even with short-acting steroids, may lead to suppressed ACTH secretion which responds sluggishly to steroid withdrawal. Where the therapeutic aim is prolonged ACTH suppression with minimal systemic glucocorticoid side effects, as, for example, in congenital adrenal hyperplasia, dexamethasone may be the preferred treatment.

The role of hydrogen-bonds in drug binding. (1989)

Hydrogen-bonds play a crucial role in determining the specificity of ligand binding. Their important contribution is explicitly incorporated into a computational method, called GRID, which has been designed to detect energetically favourable ligand binding sites on a chosen target molecule of known structure. An empirical energy function consisting of a Lennard-Jones, an electrostatic and a hydrogen-bonding term is employed. The latter term is found to be necessary because spherically symmetric atom-centred forces alone may not adequately reproduce the geometry of two interacting molecules. The hydrogen-bonding term is dependent on the length and orientation of the hydrogen-bond. Its functional form also varies according to the chemical nature of both the hydrogen-bond donor and acceptor atoms, and has been modelled to fit experimental observations of crystal structures. The mobility of the hydrogen-bonding hydrogens is considered analytically in calculating the hydrogen-bond energy. The hydrogen-bonding energy functions will be described and their application will be demonstrated on molecules of pharmacological interest where hydrogen-bonds influence the binding of ligands.

VHE trial over Mobile IP (2002)

Because surfing the World Wide Web and extending multimedia sessions for the benefit of mobile users will be basic requirements for the 21st century, the support of multimedia services in a seamless manner becomes an important feature of future telecommunication networks. Due to this increasing demand for advanced service offering at any place and on any terminal, developments in telecommunication infrastructures are changing the current global networking world. In this perspective, the virtual home environment (VHE) appears as a key concept for the 3rd generation mobile networks as the Universal Mobile Telecommunication System (UMTS). It promises mobile users the ability of accessing a large range of personalized services, whatever the location or the terminal. In fact, it allows global service portability. Among other services, Internet/Intranet applications are of course attractive targets. In parallel to the works on the VHE realization, the ongoing studies in the different standardization bodies (3GPP, 3GPP2, MWIF, IETF, 3GIP) indicate that the future telecommunication systems will be IP-based. And if SIP and H.323 are natural candidates for voice over IP (VoIP) applications, Mobile IP could play an important part for the mobility management in those new generation networks. This IETF protocol allows transparent routing of IP datagrams to mobile nodes in the wide Internet. The EURESCOM Project P920 investigated the provision of VHE services through an all-IP architecture and a VHE trial was implemented, tested and evaluated. The activities reported here focus on a web based VHE realization in which Mobile IP is used as a mobility management protocol and on events happening from the end user viewpoint, when this user wants to reach personalized services in a mobility context.
Content-based image retrieval for brain MRI: An image-searching engine and population-based analysis to utilize past clinical data for future diagnosis (2015)

Radiological diagnosis is based on subjective judgment by radiologists. The reasoning behind this process is difficult to document and share, which is a major obstacle in adopting evidence-based medicine in radiology. We report our attempt to use a comprehensive brain parcellation tool to systematically capture image features and use them to record, search, and evaluate anatomical phenotypes. Anatomical images (T1-weighted MRI) were converted to a standardized index by using a high-dimensional image transformation method followed by atlas-based parcellation of the entire brain. We investigated how the indexed anatomical data captured the anatomical features of healthy controls and a population with Primary Progressive Aphasia (PPA). PPA was chosen because patients have apparent atrophy at different degrees and locations, thus the automated quantitative results can be compared with trained clinicians' qualitative evaluations. We explored and tested the power of individual classifications and of performing a search for images with similar anatomical features in a database using partial least squares-discriminant analysis (PLS-DA) and principal component analysis (PCA). The agreement between the automated z-score and the averaged visual scores for atrophy (r = 0.8) was virtually the same as the inter-evaluator agreement. The PCA plot distribution correlated with the anatomical phenotypes and the PLS-DA resulted in a model with an accuracy of 88% for distinguishing PPA variants. The quantitative indices captured the main anatomical features. The indexing of image data has a potential to be an effective, comprehensive, and easily translatable tool for clinical practice, providing new opportunities to mine clinical databases for medical decision support.
Fis binding in the dnaA operon promoter region (1996)

The region between the rpmH and dnaA genes contains five promoters that divergently express the ribosomal protein L34 and the proteins of the dnaA operon, including DnaA, the beta clamp of DNA polymerase III holoenzyme, and RecF. The DNA-binding protein Fis was shown by the band shift assay to bind near the rpmHp2 and dnaAp2 promoters and by DNase I footprinting to bind to a single site in the dnaAp2 promoter overlapping the -35 and spacer sequences. There were no observable differences in Fis affinity or the angle of bending induced by Fis between methylated and unmethylated DNA fragments containing the Fis binding site in the dnaAp2 promoter. Fis directly or indirectly represses the expression of DnaA protein and the beta clamp of DNA polymerase III. A fis null mutant containing a dnaA-lacZ in-frame fusion had twofold greater beta-galactosidase activity than a fis wild-type strain, and induced expression of Fis eliminated the increase in activity of the fusion protein. A two- to threefold increase in the levels of DnaA and beta clamp proteins was found in a fis null mutant by immunoblot gel analysis.
Data fusion and tracking using HMMs in a distributed sensor network (1997)

This work deals with the problem of multiple target tracking, from the measurements made on a field of passive sonars activated by an active sonar (multistatic network). The difficulties encountered then are of two kinds: each sensor alone does not provide full observability of a target, and multiple, possibly maneuvering targets moving in a cluttered environment must be dealt with. The algorithm presented here is based on a discrete Markovian modelization of the targets evolution in time. It starts with a fusion of the detections obtained at each measurement time. Tracking and target motion analysis (TMA) are next achieved thanks to dynamic programming (DP). This approach leads to multiple and maneuvering target tracking, with few assumptions; for instance, the use of deterministic target state models are avoided. Simulation results are presented and discussed.
SoftLight: Adaptive visible light communication over screen-camera links (2016)

Screen-camera links for Visible Light Communication (VLC) are diverse, as the link quality varies according to many factors, such as ambient light and camera's performance. This paper presents SoftLight, a channel coding approach that considers the unique channel characteristics of VLC links and automatically adapts the transmission data rate to the link qualities of various scenarios. SoftLight incorporates two new ideas: (1) an expanded color modulation interface that provides soft hint about its confidence in each demodulated bit and establishes a bit-level VLC erasure channel, and (2) a rateless coding scheme that achieves bit-level rateless transmissions with low computation complexity and tolerates the false positive of bits provided by the soft hint enabled erasure channel. SoftLight is orthogonal to the visual coding schemes and can be applied atop any barcode layouts. We implement SoftLight on Android smartphones and evaluate its performance under a variety of environments. The experiment results show that SoftLight can correctly transmit a 22-KByte photo between two smartphones within 0.6 second and improves the average goodput of the state-of-the-art screen-camera VLC solution by 2.2.
Modelling of blood glucose profiles non-invasively using a neural network algorithm (2003)

Monitoring blood glucose levels of Insulin-Dependent-Diabetes-Mellitus (IDDM) is essential for detecting onset of hypoglycaemia and hyperglycaemia. We have developed a method based on a neural network algorithm for estimating blood glucose levels non-invasively using only physiological parameters such as skin impedance and heart rate. Results have shown that an accuracy of 10% can be achieved.

Accelerating non-Cartesian sense for large coil arrays: Application to motion compensation in multishot DWI (2012)

Multi-shot sequences are often combined with techniques such as parallel imaging to achieve high fidelity images. For non-Cartesian sampling schemes, the reconstruction of such data becomes extremely computationally intensive. The problem of motion compensated SENSE reconstruction of non-Cartesian diffusion weighted images falls into a similar setting, when phase corrections are involved. Here we propose a new pipeline for the fast reconstruction of such data. The large array of composite sensitivity functions are replaced by a low-dimensional set of virtual sensitivity functions using a principal component analysis, thus enabling the evaluation of very few Fourier transforms. The time consuming gridding steps are replaced by a more efficient multiplication in the k-space, enabling further simplifications. Significant acceleration of reconstruction time is shown to be achieved with the new scheme. The algorithm in the general setting can accelerate SENSE reconstruction for large coil arrays.
Study of the Dendritic Growth of Ni–Co Alloys Electrodeposited on Cu Substrates (2010)

Ni-Co alloy deposits and their parent metals were formed on Cu substrates by electrolysis under different current densities applied in the galvanostatic regime. A quantitative scanning electron microscopy technique was employed to study the morphology and surface roughness of the obtained deposits. The structure of the deposits is governed by the nature of depositing ions and quantity of evolved hydrogen. The cauliflower morphology and the highest mean surface roughness values are the results of electrodeposition from the Ni containing bath. The structure of the Co deposits formed under the same conditions and determined by the formation of the hexagonal close-packed phase results in a more uniform grain size distribution and formation of smoother platelet deposits. The mean surface values of the parent metals are independent of the current density. The dendritic growth is a special case of a structure formed only in the Ni-Co alloy deposition at selected, high current densities of 220 and 400 mA cm-2. The dendrites obtained at a higher current density of 400 mA cm-2 have shown more developed structures with smaller dendrites that have more pronounced secondary branch and high order branches. © 2010 The Electrochemical Society.
Evidence supporting that the excess of the sVEGFR-1 concentration in maternal plasma in preeclampsia has a uterine origin (2005)

Plasma concentration of sVEGFR-1 was higher in the uterine vein than in the antecubital vein in women with preeclampsia. This provides evidence supporting the concept that the uterus is a potential source of the excess circulating sVEGFR-1 concentration in preeclamptic women.
