A Genetic Polymorphism in the Renin Gene of Dahl Rats Cosegregates with Blood Pressure (1989)

Blood pressure is influenced by multiple genetic loci whose identities are largely unknown. A restriction fragment length polymorphism (RFLP) in the renin gene was found between Dahl salt-hypertension-sensitive (S) and Dahl salt-hypertension-resistant (R) rats. In an F2 population derived from crossing S and R rats, the renin RFLP cosegregated with blood pressure. One dose of the S-rat renin allele was associated with an increment in blood pressure of approximately 10 mmHg, and two doses of this allele increased blood pressure approximately 20 mmHg. From this it can be definitively concluded that in the rat the renin gene is, or is closely linked to, one of the genes regulating blood pressure.
The Intervening Hand (1999)

A case study method was used to investigate the regional Bell operating companies (RBOCs) and to develop an inductive model based on their international expansion processes. The model consists of three phases, with two abrupt turning points during the companies' first 8 years of international expansion. The turning points are the result of deliberate top management interventions that provided forward thrust from one phase to the next. Those interventions highlight the role of strategic choice, which had been lacking in previous international expansion models. Given the prominent role of strategic choice, the authors link the international expansion model to the strategy-making process literature and address the larger issue of how new strategic directions are formed within organizations facing industry deregulation.
Cyber security competencies : cyber security education and research in Finnish universities (2015)

The revolution in information technology that began in the 1990s has been transforming Finland into an information society. Imaginative data processing and utilization, arising from the needs of citizens and the business community, are some of the most important elements in a thriving society. Information and know-how have become key ‘commodities’ in society, and they can be utilized all the more efficiently through information technology. Individuals, public and private organizations alike depend on the cyber world. From the citizens using social media, to banks growing their business, to law enforcement supporting national security – every sector of the society is increasingly dependent upon technology and networked systems. While the public sector, the economy and the business community as well as citizens benefit from globally networked services, the digital IT society contains inherent vulnerabilities which may generate security risks to citizens, the business community or the vital functions of society. Without sufficient awareness of the risks in cyber world, however, behavioral decisions and unseen threats can negatively impact the security of the critical infrastructure and can cause physical damage in the real world. On an individual level, what is at stake is the vulnerability of each individual user in cyber world. As the world grows more connected through cyber world, a highly skilled cyber security workforce is required to secure, protect, and defend national critical information infrastructure. Across the private and public sector organizations are looking for well-trained professionals to assess, design, develop, and implement cyber security solutions and strategies. While the demand for cyber security professionals is high, the supply is low. Meeting the growing demand for cyber security professionals begins in the education system. The most efficient custom to increase cyber security is the improvement of the know-how. The cyber security strategies and development plans require the improvement of the know-how of the citizens and actors of the economic life and public administration. Pursuant to Finland’s Cyber Security Strategy (2013) “the implementation of cyber security R&D and education at different levels does not only strengthen national expertise, it also bolsters Finland as an information society”. In this paper are analyzed the know-how demands and needs of the cyber security which the different actors of the cyber world present. The know-how demands and needs are compared with the cyber security research and education which is offered in Finland's universities. The paper is based on a survey conducted on Finnish universities in 2013 and 2014 and on the analysis of its results.
A hybrid delta-sigma modulator with adaptive calibration (2003)

High-order delta-sigma ADCs can achieve wide dynamic ranges at a relatively low oversampling ratio. As high-order modulators may cause instability, a new delta-sigma modulator structure employing hybrid integrators and adaptive calibration is proposed. Hybrid integrators do not suffer from saturation, and they can be applied for high-order modulators without stability problems. The proposed structure uses adaptive calibration to mitigate the performance degradation caused by mismatches between analog and digital paths of hybrid integrators. Behavioral simulations of a fourth-order delta-sigma modulator show that the proposed structure can achieve a significant improvement in dynamic range.
Application of Image SIFT Features to the Context of CBIR (2008)

This paper is mainly concerned with the application of a kind of distinctive local invariant feature i.e. Lowe's SIFT feature for the purpose of CBIR, instead of the usually used global feature and local statistical feature based on image segmentation. In our CBIR system, the visual contents of the query image and the database images are extracted and described by the 128-dimensional SIFT feature vectors. The KD-tree with the best bin first(BBF), an approximate nearest neighbors(ANN) search algorithm, is used to index and match those SIFT features. As our contribution, a modified voting scheme called nearest neighbor distance ratio scoring (NNDRS) is put forward to calculate the aggregate scores of the corresponding candidate images in the database respectively. By sorting the database images according to their aggregate scores in descending order, the top few similar images are shown to users as the retrieval results. Additionally, RANSAC can be adopted as a geometry verification method to re-check the results and remove the false matches. Experiments show that our approach can obtain high recall and high precision in the context of CBIR on the famous image databases ZuBud.
Mechanism of termination of DNA replication of <i>Escherichia coli</i> involves helicase–contrahelicase interaction (2001)

Using yeast forward and reverse two-hybrid analyses, we have discovered that the replication terminator protein Tus of Escherichia coli physically interacts with DnaB helicase in vivo. We have confirmed this protein-protein interaction in vitro. We show further that replication termination involves protein-protein interaction between Tus and DnaB at a critical region of Tus protein, called the L1 loop. Several mutations located in the L1 loop region not only reduced the protein-protein interaction but also eliminated or reduced the ability of the mutant forms of Tus to arrest DnaB at a Ter site. At least one mutation, E49K, significantly reduced Tus-DnaB interaction and almost completely eliminated the contrahelicase activity of Tus protein in vitro without significantly reducing the affinity of the mutant form of Tus for Ter DNA, in comparison with the wild-type protein. The results, considered along with the crystal structure of Tus-Ter complex, not only elucidate further the mechanism of helicase arrest but also explain the molecular basis of polarity of replication fork arrest at Ter sites.
Spin‐Crossover Materials (2013)

The phenomenon of spin-crossover has a large impact on the physical properties of a solid material, including its colour, magnetic moment, and electrical resistance. Some materials also show a structural phase change during the transition. Several practical applications of spin-crossover materials have been demonstrated including display and memory devices, electrical and electroluminescent devices, and MRI contrast agents. Switchable liquid crystals, nanoparticles, and thin films of spin-crossover materials have also been achieved. Spin-Crossover Materials: Properties and Applications presents a comprehensivesurvey of recent developments in spin-crossover research, highlighting the multidisciplinary nature of this rapidly expanding field. Following an introductory chapter which describes the spin-crossover phenomenon and historical development of the field, the book goes on to cover a wide range of topics including. Spin-crossover in mononuclear, polynuclear and polymeric complexes. Structure: function relationships in molecular spin-crossover materials. Charge-transfer-induced spin-transitions. Reversible spin-pairing in crystalline organic radicals. Spin-state switching in solution. Spin-crossover compounds in multifunctional switchable materials and nanotechnology. Physical and theoretical methods for studying spin-crossover materials. Spin-Crossover Materials: Properties and Applications is a valuable resource for academic researchers working in the field of spin-crossover materials and topics related to crystal engineering, solid state chemistry and physics, and molecular materials. Postgraduate students will also find this book useful as a comprehensive introduction to the field.
A Pattern Recognition Approach to Acoustic Emission Data Originating from Fatigue of Wind Turbine Blades (2017)

The identification of particular types of damage in wind turbine blades using acoustic emission (AE) techniques is a significant emerging field. In this work, a 45.7-m turbine blade was subjected to flap-wise fatigue loading for 21 days, during which AE was measured by internally mounted piezoelectric sensors. This paper focuses on using unsupervised pattern recognition methods to characterize different AE activities corresponding to different fracture mechanisms. A sequential feature selection method based on a k-means clustering algorithm is used to achieve a fine classification accuracy. The visualization of clusters in peak frequency-frequency centroid features is used to correlate the clustering results with failure modes. The positions of these clusters in time domain features, average frequency-MARSE, and average frequency-peak amplitude are also presented in this paper (where MARSE represents the Measured Area under Rectified Signal Envelope). The results show that these parameters are representative for the classification of the failure modes.
Coherence and polarization of light propagating through scattering media and biological tissues (1998)

The degree of polarization of light propagating through scattering media was measured as a function of the sample thickness in a Mach-Zehnder interferometer at a wavelength of lambda = 633 nm. For polystyrene microspheres of diameters 200, 430, and 940 nm, depolarization began to appear for thicknesses larger than 23, 19, and 15 scattering mean free paths (SMFP's), respectively, where the coherently detected scattered component dominates the ballistic component. For large particles (940 nm) the initial polarization survived partially in the scattering regime and progressively vanished up to the detection limit of our setup. This phenomenon was similarly observed in diluted blood from 12.5 to 280 SMFP's. Beyond this thickness the fluctuating parallel and crossed components of polarization became random. A dual-channel interferometer allowed us to detect simultaneously the low-frequency fluctuations of both polarized components through a few millimeters in liver tissue.
Effect of pH on Shear Strength Behavior of Granular Soil (2015)

In this research, the performances of pH value on shear strength behavior of granular soil have been studied. The shear strength of soil is an important term in most of the foundation engineering problems such as the bearing capacity of shallow foundation, slope stability of dam/embankment and lateral earth pressure on retaining walls. A series of direct shear tests were conducted on two types of dry granular soils (taken from Rangpur and Rajshahi areas of Bangladesh) with different pH value (pH = 0, pH = 3.0, pH = 5.0, pH = 7.0 and pH = 9.0). Hydrochloric acid (HCl) and ammonia (NH 4 ) solution were used to monitor the pH of the solution for about 30 days. In all, 15 specimens of each type of soils were considered for direct shear test with dry condition at a constant density. The specimens were prepared by static compaction with different pH values solution (0, 3, 5, 7 and 9) at same void ratio. Experiment result shows that the shear strength increase with increase of pH values of soil.

Sexuality and The Midlife Woman (1990)

Both physical and psychological factors affect the sexual interest and behavior of women at midlife. Hot flashes and genitourinary atrophy are the major menopausal complaints and may affect the ease and comfort of sexual exchange, although hormone replacement therapy can be helpful in reducing these symptoms. Changes in the sexual response cycle occur as well and may be attributable to the psychological and/or physical effects of aging, the partner's physical or psychological difficulties and/or the hormonal changes associated with the climacteric. Many women note a decline in sexual desire during the climacteric years, although orgasmic response is usually unimpaired. Hysterectomy, the second most commonly performed major surgical operation, can either enhance or diminish sexual comfort, depending on the women's preoperative distress and expectations. Often, sexual difficulties can be avoided at midlife by alterations in the sexual script.

Agarose-encapsulated adsorbents. (1979)

A method is described for the encapsulation of ion-exchange and adsorbent resins of native particle diameter 0.2-1.0 mm into agarose spheres of diameter 5-10 mm. Plasma components diffuse rapidly through the agarose coating, but blood corpuscles have no direct access to the resins. At least 0.3 g of resin can be incorporated into 1 g of the agarose beads, so that the effective surface area with regard to erythrocytes, thrombocytes, and leucocytes is reduced by a factor of at least 5, and up to 20, depending on the native resin particle size. Pulverised active charcoal, or resins in powder form can also be encapsulated in this manner. The haemocompatibility of the agarose coating seems to be considerably more acceptable than that of the adsorbents in their native state.
Clindamycin-associated enterocolitis in guinea pigs: evidence for a bacterial toxin (1979)

Experimental enterocolitis was induced in guinea pigs by intraperitoneal injection of clindamycin. Specimens of feces were collected daily in phosphate-buffered saline (pH 7.0) and pooled every second day. The pooled samples were centrifuged to remove solids, and the supernatant was sterilized by membrane filtration. The sterile fecal supernatants were then dialyzed for 48 h against two 15-liter changes of phosphate-buffered saline and subsequently tested for toxicity in cultured monolayers of mouse adrenal cells. A filterable toxin(s) was found in the fecal supernatants on days 2, 4, and 6 postchallenge and not in pretreatment samples. The toxin(s) caused enterocolitis when administered orogastrically to healthy animals and altered the morphology of cultured mouse adrenal cells. The alteration of adrenal cell morphology was neutralized by specific antitoxin to Clostridium histolyticum.
Theories of violence and their influence on the practice of counselling (2004)

Why violence occurs in the world continues to provoke heated debate within the counselling fraternity, whether the violence be familial, spousal or societal. Arguments can focus upon issues of moral responsibility and considerations of whether or not violent behaviour is under the control of the perpetrator. Richard Johnson argues that to gain further insight into the complex processes that instigate violence a perspective that integrates biological, psychological and sociopolitical theories is needed. Such a model enables the helping professions to instigate effective and judicious practical interventions that address violent tendencies in clients. Without a clear model or theory of violence, the counsellor risks falling victim to manipulative argument or distorted assumptions, and as a consequence may foster diffusion, encourage abdication of responsibility or maintenance of status quo, or exert inappropriate power themselves. Clinical vignettes are provided to illustrate the complexities of this clinical concern. (editor abstract)
Radar cross-section enhancement of dihedral corner reflector using fractal-based metallo-dielectric structures (2006)

Effective use of fractal-based metallo-dielectric structures for enhancing the radar cross-section (RCS) of dihedral corner reflectors is reported. RCS enhancement of about 30 dBsm is obtained for corner reflectors with corner angles other than 90°. This may find application in remote sensing and synthetic aperture radar.
Maternal methadone use in pregnancy: factors associated with the development of neonatal abstinence syndrome and implications for healthcare resources (2009)

Objectives The objectives of this study were to investigate factors associated with the development of neonatal abstinence syndrome (NAS) and to assess the implications for healthcare resources of infants born to drug‐misusing women. Design Retrospective cohort study from 1 January 2004 to 31 December 2006. Setting Inner‐city maternity hospital providing dedicated multidisciplinary care to drug‐misusing women. Population Four hundred and fifty singleton pregnancies of drug‐misusing women prescribed substitute methadone in pregnancy. Methods Case note review. Main outcome measures Development of NAS and duration of infant hospital stay. Results 45.5% of infants developed NAS requiring pharmacological treatment. The odds ratio of the infant developing NAS was independently related to prescribed maternal methadone dose rather than associated polydrug misuse. Breastfeeding was associated with reduced odds of requiring treatment for NAS (OR 0.55, 95% CI 0.34–0.88). Preterm birth did not influence the odds of the infant receiving treatment for NAS. 48.4% infants were admitted to the neonatal unit (NNU) 40% of these primarily for treatment of NAS. The median total hospital stay for all infants was 10 days (interquartile range 7–17 days). Infants born to methadone‐prescribed drug‐misusing mothers represented 2.9% of hospital births, but used 18.2% of NNU cot days. Conclusions Higher maternal methadone dose is associated with a higher incidence of NAS. Pregnant drug‐misusing women should be encouraged and supported to breastfeed. Their infants are extremely vulnerable and draw heavily on healthcare resources.
Developing a system for securely time-stamping and visualizing the changes made to online news content (2018)

Nowadays, the Internet is indispensable when it comes to information dissemination. People rely on the Internet to inform themselves on current news events, as well as to verify facts. We, as a community, are quickly approaching an 'electronic information age' where the majority of information will be distributed electronically and tools to preserve this information will become essential. While archiving online digital information is a good way to preserve online information for future generations, it has many disadvantages including the easy manipulation of archived information, e.g. by the archiving authority. Online information is also prone to getting hacked or being taken offline. Therefore, it is necessary that archived online news information is securely time-stamped with the date and time when it was first archived in a way that cannot be manipulated. The process of 'trusted timestamping' is an established approach for claiming that particular digital information existed at a particular 'point in time' in the past. However, traditional approaches for trusted timestamping depend on the time-stamping authority's fidelity. Directly embedding the hash of a digital file into the blockchain of a cryptocurrency is a more recent method that allows for secure time-stamping, since digital information is stored as part of the transaction information in, e.g. Bitcoin's, blockchain, and not stored at a centralized time-stamping authority. However, there is no system yet available, which uses this approach for archiving and time-stamping online news articles. Therefore, the aim of this thesis is to develop a system that 1) enables decentralized trusted time-stamping of web and news articles as a means of making future manipulation of online information identifiable, and 2) allows users to determine the authenticity of articles by checking different versions of the same article online.
Velocity analysis by iterative profile migration (1987)

In conventional seismic processing, velocity analysis is performed by using the normal moveout (NMO) equation which is based on the assumption of flat, horizontal reflectors. Imaging by migration (either before or after stack) is done normally in a subsequent step using these velocities. In this paper, velocity analysis and imaging are combined in one step, and migration itself is used as a velocity indicator. Because, unlike NMO, migration can be formulated for any velocity function, migration‐based velocity analysis methods are capable of handling arbitrary structures, i.e., those with lateral velocity variations. In the proposed scheme, each shot gather (profile) is migrated with an initial depth‐velocity model. Profile migration is implemented in the (x, ω) domain, but the actual implementation of profile migration is not critical, as long as it is not done in a spatial‐wavenumber domain, which would preclude handling of lateral velocity variations. After migration with an initial velocity model, the ...
Cradle to Cradle Evolution: How Can Legislation Assist? (2010)

Environmentalists fall into two groups: those who think we are hopelessly entangled in an utter catastrophe of our own making and those who think we have the technical know-how to cope or adapt to the future we have created. This research paper is devised with the latter in mind and explores the theory around waste not existing in the future. It also reviews opposing environmental discourses around the current issues and whether global legislation is the way to achieve this theory in the future.
Towards Personalized Medicine in Pediatric Cancer: Genome-Wide Strategies to Investigate Cancer Risk and Response to Therapy (2012)

Cancer results from the complex actions and interactions of multiple genetic, epigenetic and environmental factors that lead to the acquisition of somatic alterations abrogating the function of a variety of normal regulatory networks. While there has been considerable progress in understanding the genetic basis of cancer, only rarely has this knowledge translated to the development of rational therapeutics. In fact, the majority of children with cancer are still treated with nonspecific cytotoxic agents, and the remarkable strides made in curing these diseases have come largely from improvements in chemotherapy, radiation, cellular transplantation, and supportive care rather than from the use of targeted therapies.
