Shape-Induced, Hexagonal, Open Frameworks: Rubidium Ion Complexed Cucurbituril (1999)

A honeycomb structure is shown by the one-dimensional coordination polymer comprising D<sub>6h</sub> -symmetric cucurbituril molecules and rubidium ions (see picture). The cucurbituril molecules stack atop one another and show coordination of their carbonyl groups to the rubidium ions in between. The shape and symmetry of the building blocks encourage the coordination polymer chains to be arranged in such a way as to produce an open-framework structure with large, linear, hexagonal channels.
Oily Drill Cuttings - From Waste to Resource (2000)

Abstract Discharge of drill cuttings generated offshore while drilling with oil-based drilling fluids in the North Sea areas was banned in 1994. This paper outlines how oily drill cuttings may be used in soil, and presents results of a meso-scale growth experiment where fresh oily cuttings were used in plant growth media. Growth experiments were performed at meso-scale. A standard test species, Rye gras, was grown in pots containing oily cuttings mixed with different soils, and peat in varying ratios. The physical conditions of the oily drill cuttings were generally within current accept criteria for soil meant for agricultural purposes. Measured concentrations of heavy metals and organic components complied with current environmental standards. Analyses included crop yield, assimilation of heavy metals, soil chemistry, and toxicological tests in selected blends of materials. The collected data provide a basis in evaluation of alternative applications of the technology, and issues that should be addressed when environmental impacts in general are discussed. The experiments suggest that oily drill cuttings is applicable as a constituent of growth media, preferably used for cultivation of plants used for other purposes than consumption. Cuttings may be added in significant proportions to natural soils. Thus it should be considered as a viable alternative for final disposal of oily drill cuttings.
Artificial Embolic Occlusion of the Terminal Internal Carotid Artery in the Treatment of Carotid-Cavernous Fistula (1968)

HE most radical and effective treatment of carotid-cavernous fistula consists of isolation of the cavernous portion of the internal carotid artery by ligation in the neck after intracranial clipping of its terminal portion. Because of its hazards, however, this procedure is often avoided, and the results are correspondingly poor. This report describes the successful intraluminal occlusion of the terminal internal carotid artery by embolization with a porcelain bead, thus eliminating the need for craniotomy. Case Report A 42-year-old man had been brutally beaten about the head. He was admitted in deep shock in a stuporous condition with severe facial and scalp lacerations, multiple linear fractures, and a severe right parietal depressed fracture. After treatment for shock, the depressed fragment was removed, a large epidural hematoma was evacuated, and the middle meningeal artery occluded close to the foramen spinosum. The dura had not been damaged. The patient made an uneventful recovery. Two months after discharge the patient became aware of a pulsatile bruit over the left eye; in the course of the next 2 weeks this eye protruded severely. There was chemosis and engorgement of conjunctival vessels in both eyes, more marked in the left. The optic discs were normal but the retinal veins were slightly engorged. There was no visual impairment. Intraocular pressure was elevated to 22 mm Hg in the right eye and 24 mm Hg in the left eye. All over the cranium a blowing bruit could be heard, louder over the left eye, and synchronous with the pulse and abolished by carotid compression. Left carotid angiography (Fig. 1 left) dem
Inter-device spacing issues within wave and tidal energy converter arrays (2010)

Inter-device spacing within wave and tidal arrays will affect many aspects of array performance including power production, installation, maintenance and the effect upon the wider flow field. It follows that inter-device spacing within an array will vary based upon a number of factor including (but not limited to) characteristics of the incoming resource, water depth, device type and installation/maintenance methods. Therefore it is clear that the issues surrounding interaction effects within arrays are complex with a high degree of linkage between certain aspects of design. Despite the low level of understanding of many issues surrounding wave and tidal energy arrays there are a number of areas where guidance can be given to developers in order to assist in array design. One such area is the classification of arrays by size and complexity. Other more generic advice can be given to advise upon potential interaction effects whilst guiding early array design to encompass knowledge gathering to inform subsequent arrays that are greater in size and complexity

Biofouling and antifouling (2004)

Most benthic organisms produce planktonic larvae in their life cycles; larval settlement and metamorphosis are influenced by many environmental factors, especially chemical cues originating from conspecific adults, prey organisms, and substrates. On the other hand, larval settlement of other species endangers the survival of benthic organisms which therefore have antifouling defense. Marine natural products involved in biofouling and antifouling are described.
Synthesis of a holographic image velocity filter using the nonlinear photorefractive effect (1988)

We demonstrate a technique by which components of an image moving with a given speed and direction may be selectively enhanced. By using the strong grating velocity sensitivity of the nonlinear photorefractive response, we show that a BSO crystal used in a schlieren imaging system may be used as a real-time velocity filter. The velocity selectivity, tunability and resolution constraints of this system are discussed in detail.
Electrochemical carbon capture processes for mitigation of CO2 emissions (2022)

Carbon capture and storage (CCS) is essential if global warming mitigation scenarios are to be met. However, today's maturing thermochemical capture technologies have exceedingly high energy requirements and rigid form factors that restrict their versatility and limit scale. Using renewable electricity, rather than heat, as the energy input to drive CO<sub>2</sub> separations provides a compelling alternative to surpass these limitations. Although electrochemical technologies have been extensively developed for energy storage and CO<sub>2</sub> utilization processes, the potential for more expansive intersection of electrochemistry with CCS is only recently receiving growing attention, with multiple scientific proofs-of-concept and a burgeoning pipeline with numerous concepts at various stages of technology readiness. Here, we describe the emerging science and research progress underlying electrochemical CCS processes and assess their current maturity and trajectory. We also highlight emerging ideas that are ripe for continued research and development, which will allow the impact of electrochemical CCS to be properly assessed in coming years.

ALS Clinical Trials Review: 20 Years of Failure. Are We Any Closer to Registering a New Treatment? (2017)

Amyotrophic lateral sclerosis (ALS) is a devastating condition with an estimated mortality of 30,000 patients a year worldwide. The median reported survival time since onset ranges from 24 to 48 months. Riluzole is the only currently approved mildly efficacious treatment. Riluzole received marketing authorization in 1995 in the USA and in 1996 in Europe. In the years that followed, over 60 molecules have been investigated as a possible treatment for ALS. Despite significant research efforts, the overwhelming majority of human clinical trials (CTs) have failed to demonstrate clinical efficacy. In the past year, oral masitinib and intravenous edaravone have emerged as promising new therapeutics with claimed efficacy in CTs in ALS patients. Given their advanced phase of clinical development one may consider these drugs as the most likely near-term additions to the therapeutic arsenal available for patients with ALS. In terms of patient inclusion, CT with masitinib recruited a wider, more representative, less restrictive patient population in comparison to the only successful edaravone CT (edaravone eligibility criteria represents only 18% of masitinib study patients). The present manuscript reviews >50 CTs conducted in the last 20 years since riluzole was first approved. A special emphasis is put on the analysis of existing evidence in support of the clinical efficacy of edaravone and masitinib and the possible implications of an eventual marketing authorisation in the treatment of ALS.
Tuning of Induction Motor Drive with Torque Sensor (2018)

To achieve precise torque control of an induction motor drive, the control parameters are tuned with torque sensor before shipping the drive system. In this paper, a method to estimate the rotor resistance and the magnetizing inductance with measured test data which consist of torque, current amplitude and slip frequency is proposed. Then a torque control with look up tables (LUTs) which are built from test data is also proposed. The LUTs decide the current amplitude and the voltage amplitude based on the operating point which is defined as the condition of the motor speed and the torque command.
Analysis of glycosaminoglycan substitution in decorin by site-directed mutagenesis. (1990)

Posttranslational glycosaminoglycan attachment to decorin, a chondroitin/dermatan sulfate proteoglycan, was studied by expression of a wild-type decorin cDNA and several mutagenized forms in two types of mammalian cells. Transfection of the wild-type cDNA resulted in the synthesis of an authentic chondroitin/dermatan sulfate proteoglycan similar to the decorin molecule synthesized by cultured human fibroblasts. Conversion of the serine residue that serves as the attachment site for the sole glycosaminoglycan chain in decorin to a threonine residue greatly reduced the efficiency of the glycosaminoglycan substitution. Less than 10% of the threonine-mutated core protein acquired a glycosaminoglycan chain, whereas most of the core protein was secreted without such substitution. Expression of cDNA in which an alanine residue had been introduced into the substituted serine position resulted in the secretion of core protein with no detectable glycosaminoglycan. Conversion to alanine of either one of the glycine residues that are adjacent to the substituted serine yielded the proteoglycan form of decorin. These results show that the xylosyltransferase responsible for the initiation of the glycosaminoglycan chain on the core protein can use a threonine residue for this substitution instead of a serine residue, but that such substitution is only partial, creating a "part-time" proteoglycan. Moreover, variations are possible in the sequence context of a glycosaminoglycan-substituted serine residue without loss of glycosaminoglycan substitution. The conformation of the substitution site may therefore be important for xylosyltransferase recognition.
Assessing the effect of guideline introduction on clinical practice and outcome in patients with endometrial cancer in Japan: a project of the Japan Society of Gynecologic Oncology (JSGO) guideline evaluation committee (2017)

It was suggested that guideline introduction influenced the management of endometrial cancer at several aspects. Better organized information and continuous evaluation are necessary to understand the causal relationship between the guideline and patient outcome.
Psi: A Silicon Compiler for Very Fast Protocol Processing (1989)

Conventional protocols implementations typically fall short, by a few orders of magnitude, of supporting the speeds afforded by high-speed optical transmission media. This protocol processing bottleneck is a key hurdle in taking advantage of the opportunities presented by high-speed communications. This paper describes PSi, a silicon compiler that transforms formal protocol specifications into efficient VLSI implementations. PSi takes advantage of the parallelisms intrinsic to a given protocol to accomplish very high-speed implementations. Initial application of PSi to the IEEE 802.2 (logical link control) leads to processing rates in the order of 106 packets per second (p/s). The 802.2 was selected as a benchmark of complexity; light-weight protocols can accomplish even higher processing rates, reaching the limits set by chip clock rates (i.e., a packet per cycle). These speeds significantly exceed typical of software implementations (up to a few hundred p/s) or special hardware-assisted implementations (up to a few thousands p/s). More importantly, at these rates when the packet size is 103-4 bits the protocol throughput of 109-10 bits/sec reaches the limiting throughput afforded by memory technology. Thus, the protocol processing bottleneck is pushed to the ultimate bounds set by VLSI technologies.

CYP3A4 GENETIC VARIANT AND DISEASE-FREE SURVIVAL AMONG WHITE AND BLACK MEN AFTER RADICAL PROSTATECTOMY (2004)

The CYP3A4 genotype studied was not associated with pathological features of prostate cancer for men of either race. Unstratified analyses of men of both races and stratified analyses of white men demonstrated poorer PFS after prostatectomy for those with the G allele, but the G allele did not predict PFS among black men.
Effect of Urea, Glycerol, and Mannitol on Basilar and Labyrinthine Arteries (1988)

We studied the effect of urea, glycerol, and mannitol on basilar and labyrinthine arteries of dogs in vitro by use of tension recording methods. When the tissue was exposed to urea or glycerol, temporary relaxation of smooth muscles was initially observed, but was followed by gradually increasing contraction. With mannitol, relaxation of the smooth muscles remained stable as long as mannitol existed in the bathing solution. When the specimens were washed with normal Krebs solution after exposure to any of these three substances, large phasic contractions of the smooth muscles were observed. While only theoretical, we propose a possible explanation for the different effects of these three drugs in the improvement of hearing loss that results from Meniere's disease.
Design and optimization of a distributed, embedded speech recognition system (2008)

In this paper, we present the design and implementation of a distributed sensor network application for embedded, isolated-word, real-time speech recognition. In our system design, we adopt a parameterized-dataflow-based modeling approach to model the functionalities associated with sensing and processing of acoustic data, and we implement the associated embedded software on an off-the-shelf sensor node platform that is equipped with an acoustic sensor. The topology of the sensor network deployed in this work involves a clustered network hierarchy. A customized time division multiple access protocol is developed to manage the wireless channel. We analyze the distribution of the overall computation workload across the network to improve energy efficiency. In our experiments, we demonstrate the recognition accuracy for our speech recognition system to verify its functionality and utility. We also evaluate improvements in network lifetime to demonstrate the effectiveness of our energy-aware optimization techniques.
Structure-dynamics relationships of the ?-relaxation in flexible copolyesters during crystallization as revealed by real-time methods (1999)

The evolution of the α-relaxation during an isothermal crystallization process of a series of flexible copolyesters of hydroxybutyrate (HB) and hydroxyvalerate (HV) has been followed in real-time by wide-angle X-ray scattering and dielectric complex permittivity measurements. The change of the dielectric parameters with crystallization time can be phenomenologically described in terms of the Havriliak-Negami equation. The dielectric strength follows a sigmoidal-shaped pattern similar to that shown by the crystallinity. A reduction of the overall mobility with crystallization time of the polymeric chains in the amorphous phase has been observed. This slowing down effect depends on the HV molar content. The influence of the chain flexibility on the crystalline-induced restriction has been discussed in the light of similar studies carried out with more rigid polymers. Dielectric experiments suggest that the progressive immobilization of polymer segments as crystallization proceeds cannot be exclusively associated with the amount of crystalline material. Differences in microstructure, depending on the HV molar content, seem to be responsible for the observed behavior. The progressive broadening and symmetrization of the α-relaxation with increasing crystallization time has been explained as due to a restriction of the large-scale motions of the polymeric chains, as the material is being filled in with crystals. © 1999 John Wiley & Sons, Inc.

Transferts radiatifs dans les récepteurs-réacteurs solaires à haute température (2015)

Les projets de recherche, sur les nouveaux procedes de conversion de l'energie solaire concentree, doivent relever le defi de la simulation des recepteurs solaires. En effet, des mecanismes complexes de couplage ecoulement/rayonnement/reaction chimique/croissance de particules doivent etre simules pour developper les connaissances et les applications. Dans ce memoire, l'influence du rayonnement a ete etudiee dans un reacteur solaire de craquage du methane pour la production d'hydrogene et de particules de noirs de carbone. L'influence des transferts radiatifs a aussi ete etudiee dans des recepteurs et reacteurs volumiques poreux a particules ou en mousse ainsi que des recepteurs surfaciques plans et a cavite. De plus, des campagnes experimentales ont ete menees pour valider les modeles construits notamment ceux sur les recepteurs volumiques. La necessite d'augmenter les rendements de ces recepteurs requiert de limiter les pertes par emission thermique. C'est pourquoi, des travaux ont ete realises dans l'objectif d'etudier le gain d'efficacite que procure l'utilisation de materiaux spectralement selectifs pour des recepteurs volumiques et surfaciques a haute temperature. Pour l'ensemble de ces travaux, des modeles numeriques de transferts radiatifs (Monte Carlo, Ordonnees Discretes, 2-Flux) et de transferts couples ont ete developpes et utilises. De plus, des modeles de proprietes radiatives spectrales de parois opaques rugueuses, de milieux semi-transparents composes d'un melange gaz-particules ou d'un milieu macroporeux ou de gaz a haute temperature ont ete proposes et leurs domaines de validite etudies.
Robot Dynamic Model Identification Through Excitation Trajectories Minimizing the Correlation Influence among Essential Parameters (2014)

Robot dynamics is commonly modeled as a linear function of the robot kinematic state from a set of dynamic parameters into motor torques. Base parameters (i.e. the set of theoretically demonstrated linearly-independent parameters) can be reduced to a subset of “essential” parameters by eliminating those that are negligible with respect to their contribution in motor torques. However, generic trajectories, if not properly defined, couple the contribution of such essential parameters into the motor torques, actually reducing the estimation accuracy of the dynamics parameters. The work presented here introduces an index for evaluating correlation influence among essential parameters along an executed trajectory. Such index is then exploited for an optimal search of excitatory patterns consistent with the kinematical coupling constraints. The method is experimentally compared with the results achievable by one of the most popular IRs dynamic calibration method.
Genetic and Epigenetic Alteration in Gastric Carcinogenesis (2010)

Gastric cancer (GC) is an important cause of morbidity and mortality worldwide. In addition to environmental factors, genetic factors also play an important role in GC etiology, as demonstrated by the fact that only a small proportion of individuals exposed to the known environmental risk factors develop GC. Molecular studies have provided evidence that GC arises not only from the combined effects of environmental factors and susceptible genetic variants but also from the accumulation of genetic and epigenetic alterations that play crucial roles in the process of cellular immortalization and tumorigenesis. This review is intended to focus on the recently described basic aspects that play key roles in the process of gastric carcinogenesis. Genetic variation in the genes DNMT3A, PSCA, VEGF, and XRCC1 has been reported to modify the risk of developing gastric carcinoma. Several genes have been newly associated with gastric carcinogenesis, both through oncogenic activation (MYC, SEMA5A, BCL2L12, RBP2 and BUBR1) and tumor suppressor gene inactivation mechanisms (KLF6, RELN, PTCH1A, CLDN11, and SFRP5). At the level of gastric carcinoma treatment, the HER-2 tyrosine kinase receptor has been demonstrated to be a molecular target of therapy.
Training sequence versus cyclic prefix-a new look on single carrier communication (2001)

Orthogonal frequency-division multiplexing (OFDM), with the help of a cyclic prefix, enables low complexity frequency domain equalization, but suffers from a high crest factor. Single carrier with cyclic prefix (SC-CP) has the same advantage with similar performance, but with a lower crest factor and enhanced robustness to phase noise. The cyclic prefix is overhead, so we put more information in it by implementing this cyclic prefix as a training sequence (TS). This new training aided frequency domain equalized single carrier (TASC) scheme offers us additional known symbols and enables better synchronization and (potentially) channel estimation, with the same performance as SC-CP.
Safety and Feasibility of Transcranial Direct Current Stimulation in Pediatric Hemiparesis: Randomized Controlled Preliminary Study (2014)

Based on the results of this study, tDCS appears to be safe, feasible, and well tolerated in most children with hemiparesis. Future investigations of serial sessions of tDCS in conjunction with rehabilitation in pediatric hemiparesis are indicated to explore the benefit of a synergistic approach to improving hand function.
ILP Formulation for Monitoring-Cycle Construction Using Segment Routing (2018)

A monitoring-cycle can be easily implemented using segment routing and subject to a given maximum segment list size. In this paper, we propose the first ILP formulation (ILP1) to optimally solve the problem of covering every link in the network using monitoring-cycles and with minimum cycle cover length. To further conserve network bandwidth, we extend ILP1 to jointly minimize the total segment list size needed (ILP2). Since the time required to detect a network failure is affected by the longest cycle, we also extend ILP1 to jointly minimize the length of the longest cycle (ILP3). Finally, since all the existing network monitoring algorithms need to maintain a dedicated monitoring topology, we evaluate the gain brought by the monitoring topology using our ILPs. We found that the gain is limited, therefore we argue that maintaining a dedicated monitoring topology for monitoring-cycle construction is unnecessary.
