A seismic refraction and reflexion study of the continent-ocean transition beneath the north Biscay margin (1982)

Abstract The structure of the northern margin of the Bay of Biscay consists of a series of tilted and rotated blocks bounded by prominent listric faults whose polarity is consistently down toward the continent-ocean boundary. These blocks formed by rifting in late Jurassic - early Cretaceous time and are now thinly covered by post-rift sediments of Aptian to Recent age. Seismic refraction profiles were occupied on the shelf, on either side of and across the continent-ocean transition to the shelf, using P ubs and O bs with explosives and a 4 x 1000 in3 (4 x 16400 cm3) airgun array. Two-ship expanding spread multichannel (48-trace) seismic reflexion profiles and 30 km fixed offset reflexion profiles were located along the seismic refraction profiles on either side of the transition. A two-ship 30 km fixed offset multichannel profile was located across the transition as well as a 5 km fixed offset multichannel profile extending from the ocean crust to the shelf. Conventional 48-trace single ship multichannel profiles were located along all the refraction and two-ship reflexion lines. Interpretation of the refraction profiles has been made by using ray tracing as well as synthetic seismograms. Conventional seismic processing techniques have been used to prepare the two-ship multichannel seismic data for interpretation. The survey is believed to be the first attempt to apply two-ship multichannel seismic data to the study of the change in crustal structure of a rifted passive margin from the shelf to the ocean crust. The results from the experiment led to the identification of a zone of transition between continental and oceanic crust about 8 km wide. The seismic refraction data show progressive thinning of the continental crust from 33 km to about 5 km close to the transition zone. However, extension values calculated in the upper crust from the rotation of fault blocks are much less (1.1—1.4) and suggest that the majority of the thinning is achieved by extensive attenuation of the lower crust.
NetCube (2011)

We present a novel method for answering count queries from a large database approximately and quickly. Our method implements an approximate DataCube of the application domain, which can be used to answer any conjunctive count query that can be formed by the user. The DataCube is a conceptual device that in principle stores the number of matching records for all possible such queries. However, because its size and generation time are inherently exponential, our approach uses one or more Bayesian networks to implement it approximately. Bayesian networks are statistical graphical models that can succinctly represent the underlying joint probability distribution of the domain, and can therefore be used to calculate approximate counts for any conjunctive query combination of attribute values and “don’t cares.” The structure and parameters of these networks are learned from the database in a preprocessing stage. By means of such a network, the proposed method, called NetCube, exploits correlations and independencies among attributes to answer a count query quickly without accessing the database. Our preprocessing algorithm scales linearly on the size of the database, and is thus scalable; it is also parallelizable with a straightforward parallel implementation. We give an algorithm for estimating the count result of arbitrary queries that is fast (constant) on the database size. Our experimental results show that NetCubes have fast generation and use, achieve excellent compression and have low reconstruction error. Moreover, they naturally allow for visualization and data mining, at no extra cost.Request access from your librarian to read this chapter's full text.
Optimizing Storages for Transmission System Operation (2014)

A growing amount of congestions is expected for future operation of electrical transmission grids in Europe. Within this context, storages can be used to assist transmission system operators in daily operation and to avoid costly redispatch measures. In this paper, a research methodology to evaluate impact and interdependencies between market operation of storages and participation in redispatch measures is presented. Furthermore, a methodology for the evaluation of benefits by storages solely administrated by TSO is introduced. The methods are evaluated in a case study for the German electricity system in the year 2020.
Interactive Robots as Social Partners and Peer Tutors for Children: A Field Trial (2004)

Robots increasingly have the potential to interact with people in daily life. It is believed that, based on this ability, they will play an essential role in human society in the not-so-distant future. This article examined the proposition that robots could form relationships with children and that children might learn from robots as they learn from other children. In this article, this idea is studied in an 18-day field trial held at a Japanese elementary school. Two English-speaking "Robovie" robots interacted with first-and sixth-grade pupils at the perimeter of their respective classrooms. Using wireless identification tags and sensors, these robots identified and interacted with children who came near them. The robots gestured and spoke English with the children, using a vocabulary of about 300 sentences for speaking and 50 words for recognition. The children were given a brief picture-word matching English test at the start of the trial, af-62 KANDA, HIRANO, EATON, ISHIGURO D o N o t C o p y
The Rules of Engagement: Perspectives on Secure Messaging From Experienced Ambulatory Patient Portal Users (2017)

As secure messaging through patient portals is increasingly being used as a method of physician-patient communication, both patients and providers are looking for guidance on how to appropriately engage with each other using this tool. Patients worry about whether their use is appropriate, and providers are concerned about the content of messages, which allow them to effectively manage patient questions. Our findings suggest that additional training may help address the concerns of both patients and providers, by providing "rules of engagement" for communication via patient portals.
Genetic Algorithm for Restrictive Channel Routing Problem. (1997)

This paper presents a genetic algorithm for to the restrictive channel routing problem. The major advance of this algorithm over other GA approaches to this problem is the use of horizontal and vertical constraints in the chromosome encoding which eliminates unfeasible solutions. This representation leads to lower complexity, because repairing procedures become unnecessary; in addition the search space is reduced greatly. Competitive experimental results proving the consistency of the approach were obtained. 1 INTRODUCTION Routing is the final stage in physical design of Integrated Circuits (IC). The aim of routing is to find a topology of connections among elements of an IC in accordance with a given net list, along with other design requirements and preferences. Routing is one of the most highly constrained problems in IC design. There are many approaches such as wave and beam routing algorithms and their various modifications (Burstein1986; Shimamoto and Sakamoto 1989; ...
Reticulation pattern without honeycombing on high-resolution CT is associated with the risk of disease progression in interstitial lung diseases (2022)

Higher extent of reticulation on HRCT and never smoking appeared to associate with the risk of disease progression within 24 months in ILD patients without honeycombing. Approximately half of the patients with ILD revealed disease progression, and similar proportions were observed in patients with IPF and in other types of ILD.

A Post-Swirl Maneuvering Propulsor Application to Undersea Vehicles (2016)

A method to generate vehicle maneuvering forces from a propulsor alone has been applied to a generic undersea vehicle. Open and ducted post-swirl propulsors were configured with an upstream rotor and downstream stator row. During normal operation, the downstream stator blades are all situated at the same pitch angle and generate a roll moment to counter the torque produced by the rotor. By varying the pitch angles of the stator blade about the circumference, it is possible to generate a mean stator side force that can be used to maneuver the vehicle. In addition, the side force can be increased with increasing thrust producing side forces at very low vehicle velocities enabling low-speed maneuvering capability. The viscous, 3-D Reynolds-averaged Navier-Stokes (RANS) commercial code Fluent was used to predict the vehicle and propulsor component forces as well as the velocity field. Open and ducted geometric configurations were studied and force coefficients computed and compared with currently used control surface forces. Computations predicted that the maneuvering propulsor generated side forces equivalent to those produced by conventional control surfaces with side force coefficients on the order of 0.25 for the open propulsor at the self-propulsion point. This translates to 50% larger forces than can be generated by conventional control surfaces on 21" unmanned undersea vehicles. The ducted configuration produces maximum side force coefficients on the order of 0.15, which is still sufficient for vehicle control. Both configurations produced side forces for the Bollard pull condition indicating low-speed maneuvering capability.
Middle Cranial Fossa Transtemporal Approach to the Intrapetrous Internal Carotid Artery (1991)

Diseases involving the proximity of the internal carotid artery at the skull base require identification of this vessel in the temporal bone to gain vascular control for any maneuver in its vicinity. This article details the technique of surgical dissection and exposure of the internal carotid artery within the skull base through a transtemporal middle cranial fossa approach. The anatomic landmarks important in utilizing this procedure include the greater superficial petrosal nerve, the mandibular branch of the trigeminal nerve, and the middle meningeal artery. With this approach, the internal carotid artery can be followed throughout the carotid canal and beyond the formen lacerun to the region of the cavernous sinus. The indications and limitations of this procedure are described and several clinical applications are provided.
Reliability of Al2O3/In-Si-O-C Thin-Film Transistors with an Al2O3 Passivation Layer under Gate-Bias Stress (2018)

We investigated relationship between threshold voltage shift (ΔVth) and hole and deep traps at Al2O3 insulator/In-Si-O-C interface for In-Si-O-C thin-film transistors (TFTs) with Al2O3 dielectric using an Al2O3 passivation layer under the negative gate bias stress (NBS) and negative gate bias illumination stress (NBIS) conditions. A large ΔVth of -4.7 V was observed in TFT without an Al2O3 passivation layer (w/o) due to the three components such as hole trap (-0.9 V) at around the valence band edge, deep trap (-0.7 V) and hole trap (-3.1 V) at around fermi-level generated by absorbed O2 molecule at Al2O3 insulator/In-Si-O-C interface. The influence of absorbed O2 molecule on ΔVth could be significantly suppressed up to approximately 45 % as an Al2O3 passivation layer increases from 0 to 10 nm.
Increased HAS2‐driven hyaluronic acid synthesis in shar‐pei dogs with hereditary cutaneous hyaluronosis (mucinosis) (2011)

The Chinese shar-pei dog is known for its distinctive feature of wrinkled and thickened skin, defined as primary or hereditary cutaneous mucinosis. In a recent report, we identified the mucinous material deposited in the shar-pei skin as the polysaccharide hyaluronan (HA). In the present work, the molecular and cellular mechanisms underlying this phenotype have been identified in dermal fibroblasts isolated from shar-pei dogs. The production of HA, which appeared to be mainly associated with cell membrane protrusions and also intracellular, was higher in shar-pei fibroblasts than in control cells. The HA accumulation is related to a higher mRNA expression of the isoform HAS2 of the HA-synthesizing enzyme family, hyaluronan synthases (HAS). The higher expression of HAS2 in shar-pei fibroblasts was confirmed at the protein level. The other HAS isoenzymes, HAS1 and HAS3, and the HA-degrading enzymes, Hyal1 and Hyal2, were not differentially expressed in shar-pei fibroblasts compared with cells from control dogs. Fibroblasts from shar-pei dogs and from control dogs are morphologically different as observed by transmission electron microscopy. Scanning electron microscopy revealed a large number of cellular protrusions with associated globular deposits. Electron microscopy after labelling with biotinylated HA-binding protein confirmed an increased HA content in shar-pei fibroblasts, which could be localized in several subcellular structures. The authors propose the name hereditary cutaneous hyaluronosis (HCH) for affected dogs, because it better defines the cutaneous mucinosis of shar-pei dogs.
Improving the Diffie-Hellman Secure Key Exchange (2005)

Diffie-Hellman (DH) is a well-known cryptographic algorithm used for secure key exchange. The first appearance of DH was in 1976. The algorithm allows two users to exchange a symmetric secret key through an insecure wired or wireless channel and without any prior secrets. DH works under the domain of integers Z*/sub n/ where n = p. Here, p and /spl alpha/ are the two parameters of DH where p is a large prime number and /spl alpha/ is a generator selected from the cyclic group Z*/sub n/. In this paper, we propose two modifications of DH. The first modification is to change the domain to integer with n=2p/sup t/ where Z*/sub n/ is still cyclic and the second modification is to change the domain to Gaussian arithmetic Z*/sub n/. After implementing the three algorithms we found that the symmetric key size derived from the two modified algorithms is much greater than the classical one. Moreover, attacking the two modified algorithms using Pohlig-Hellman algorithm, using the same prime value p and private value a or b, needs much more time than the classical one.
Activity of a β‐nucleating agent for isotactic polypropylene and its influence on polymorphic transitions (2002)

Abstract The influence of a nonpigmenting β‐nucleating additive in the crystallization of isotactic polypropylene (iPP) is investigated by differential scanning calorimetry and X‐ray diffraction. It is found that this additive induces the formation of a very high level of the trigonal modification of iPP. The crystallization and melting behavior of the nucleated systems are studied as a function of the cooling and heating rates and the control of the final temperature during the cooling process. The nucleating agent exerts an important effect on the crystallization temperatures and the polymorphic transitions of iPP, delaying the β–α recrystallization process through an increase in the stability of the trigonal crystals. © 2002 Wiley Periodicals, Inc.

A novel bone conduction implant (BCI): Engineering aspects and pre-clinical studies (2010)

Percutaneous bone anchored hearing aids (BAHA) are today an important rehabilitation alternative for patients suffering from conductive or mixed hearing loss. Despite their success they are associated with drawbacks such as skin infections, accidental or spontaneous loss of the bone implant, and patient refusal for treatment due to stigma. A novel bone conduction implant (BCI) system has been proposed as an alternative to the BAHA system because it leaves the skin intact. Such a BCI system has now been developed and the encapsulated transducer uses a non-screw attachment to a hollow recess of the lateral portion of the temporal bone. The aim of this study is to describe the basic engineering principals and some preclinical results obtained with the new BCI system. Laser Doppler vibrometer measurements on three cadaver heads show that the new BCI system produces 0-10 dB higher maximum output acceleration level at the ipsilateral promontory relative to conventional ear-level BAHA at speech frequencies. At the contralateral promontory the maximum output acceleration level was considerably lower for the BCI than for the BAHA.
Loss of heterozygosity and transcriptome analyses of a 1.2 Mb candidate ovarian cancer tumor suppressor locus region at 17q25.1‐q25.2 (2005)

Loss of heterozygosity (LOH) analysis was performed in epithelial ovarian cancers (EOC) to further characterize a previously identified candidate tumor suppressor gene (TSG) region encompassing D17S801 at chromosomal region 17q25.1. LOH of at least one informative marker was observed for 100 (71%) of 140 malignant EOC samples in an analysis of 6 polymorphic markers (cen-D17S1839-D17S785-D17S1817-D17S801-D17S751-D17S722-tel). The combined LOH analysis revealed a 453 kilobase (Kb) minimal region of deletion (MRD) bounded by D17S1817 and D17S751. Human and mouse genome assemblies were used to resolve marker inconsistencies in the D17S1839-D17S722 interval and identify candidates. The region contains 32 known and strongly predicted genes, 9 of which overlap the MRD. The reference genomic sequences share nearly identical gene structures and the organization of the region is highly collinear. Although, the region does not show any large internal duplications, a 1.5 Kb inverted duplicated sequence of 87% nucleotide identity was observed in a 13 Kb region surrounding D17S801. Transcriptome analysis by Affymetrix GeneChip and reverse transcription (RT)-polymerase chain reaction (PCR) methods of 3 well characterized EOC cell lines and primary cultures of normal ovarian surface epithelial (NOSE) cells was performed with 32 candidates spanning D17S1839-D17S722 interval. RT-PCR analysis of 8 known or strongly predicted genes residing in the MRD in 10 EOC samples, that exhibited LOH of the MRD, identified FLJ22341 as a strong candidate TSG. The proximal repeat sequence of D17S801 occurs 8 Kb upstream of the putative promoter region of FLJ22341. RT-PCR analysis of the EOC samples and cell lines identified DKFZP434P0316 that maps proximal to the MRD, as a candidate. While Affymetrix technology was useful for initially eliminating less promising candidates, subsequent RT-PCR analysis of well-characterized EOC samples was essential to prioritize TSG candidates for further study.
Characterization of phosphorus and boron heavily doped LPCVD polysilicon films in the temperature range 293-373 K (2002)

In this paper, thermal properties of phosphorus and boron-doped low pressure chemical vapor deposition (LPCVD) polysilicon layers with regard to sensor applications are presented. Thermoelectric coefficient and relative resistance variations of polysilicon are investigated within the temperature range of 293-373 K. Test structures and characterization benches have been developed to obtain measurements with precision of 5%. Ion implantation has been experimented to achieve low electrical resistivities and high Seebeck coefficients. It can be seen that the temperature coefficient of resistance of doped polysilicon is negative, approaches zero, or positive depending on the doping concentration. These results are, to our knowledge, the first reported for such dopant concentrations and are important for design and optimization of high sensitivity thermal sensors using n- and p-doped-LPCVD polysilicon thermopile.
Psoroptic mange: rising prevalence in UK sheep flocks and prospects for its control (2007)

Psoroptic mange in sheep, known as scab, is caused by infestation by the astigmatid mite Psoroptes ovis (Hering). The disease has been widely prevalent and economically important in Europe for many hundreds of years. In the UK, intensive control measures over the first half of the twentieth century, involving compulsory treatment of infested flocks with organochlorine insecticides and movement controls, resulted in apparent eradication of the disease by 1952. However it was inadvertently reintroduced with imported stock in 1972. Twenty years of unsuccessful attempts to re-eradicate the disease then followed. Eventually, concern over the effects of the widespread use of acaricides on human health and the environment, and the failure of compulsory treatment programmes to control the disease, led in 1992 to deregulation of sheep scab and removal of compulsory national treatment programmes. Following this change, scab has very quickly become increasingly common and problematic. Nationally, there were estimated to be only 40 and 120 outbreaks per year in 1989 and 1992, but prevalence was estimated to have risen to 3,000 in 1997 and then 7,000 outbreaks by 2004. This has led to calls to re-impose eradication measures. Here, the biology of Psoroptes mites and the spread of the disease following reintroduction are described; the formidable obstacles to the success any proposed new eradication programme in the UK are then discussed.
Assembly, glycosylation, and secretion of the oligomeric rat prostatic binding protein in Xenopus oocytes. (1982)

Prostatic binding protein (PBP), a hormonally controlled oligomeric glycoprotein secreted by the rat ventral prostate, is composed of three different polypeptide chains, C1, C2, and C3. Microinjection of prostate mRNA into Xenopus laevis oocytes results in the synthesis, processing, and correct assembly of these three components, and also in the export of PBP into the medium. The glycosylation of component C3--the only glycopeptide of PBP--by the oocyte enzymes does not lead to the same result as in the native prostate tissue. The intracellular oocyte component contains an incompletely processed oligomannosyl core unit. Upon secretion this sugar core is further processed, probably at random because the carbohydrate chains attached to the exported C3 molecules are heterogeneous; they are also different from the oligosaccharide unit of authentic C3. However, tunicamycin experiments show that glycosylation is neither a prerequisite for secretion nor for the assembly of PBP, at least in oocytes.
A novel DNA methylation signature is associated with androgen receptor activity and patient prognosis in bone metastatic prostate cancer (2021)

A promoter methylation signature classifies PC bone metastases into two groups and predicts tumor AR activity and patient prognosis after ADT. The explanation for the methylation diversities observed during PC progression and their biological and clinical relevance need further exploration.
