A machine learning approach for estimation of shallow water depths from optical satellite images and sonar measurements (2013)

There has been a rapid growth in the field of remote sensing and its various applications in the area of water management. Nowadays, there are several remote sensing techniques that can be used as a source to derive bathymetry data along coastal areas. The key techniques are: sonar (sound navigating and ranging), LiDAR (light detection and ranging) and high-resolution satellite images. The present paper describes a method which was developed and used to create a shallow water bathymetry data along the Dutch side of Sint Maarten Island by combining sonar measurements and satellite images in a nonlinear machine learning technique. The purpose of this work is to develop a bathymetry dataset that can be used to set up physically-based models for coastal flood modelling work. The nonlinear machine learning technique used in the work is a support vector machine (SVM) model. The sonar data were used as an output whereas image data were used as an input into the SVM model. The results were analysed for three depth ranges and the findings are promising. It remains to further verify the capacity of the new method on a dataset with higher resolution satellite imagery.
Research for room-temperature magnetic refrigerants in <i>R</i> <i>x</i>Ce2−<i>x</i>Fe17 series (1991)

The Curie temperature Tc of some iron-based pseudobinary alloys such as RxCe2−xFe17, can be adjusted to room temperature by changing x in the range from 0 to 2 when R is Y or Pr. Therefore the room-temperature magnetocaloric effects (RTME) can be greatly increased. When R=Pr and x=1.5, the RTME of the alloy reaches the maximum, which is greater than that of Fe by a factor 30 (about one-half that of Gd). The results are explained in terms of the phase diagram and the critical exponent law.
The transcription factor YY1 binds to negative regulatory elements in the human cytomegalovirus major immediate early enhancer/promoter and mediates repression in nonpermissive cells (1994)

We have previously shown that repression of human cytomegalovirus (HCMV) major immediate early (IE) gene expression in non-permissive human teratocarcinoma (T2) cells is associated with a number of nuclear factors which bind to the imperfect dyad symmetry located in the modulator region upstream of the major IE enhancer as well as to the 21 bp repeat elements within the enhancer. Differentiation of T2 cells with retinoic acid (RA) results in a decrease in binding of some of these nuclear factors to these sites and deletion of these specific binding sites from major IE promoter/reporter constructs results in increased IE promoter activity in normally non-permissive cells. In this study, we demonstrate that the transcription factor YY1, which can negatively regulate the adeno-associated virus P5 promoter, directly binds to both the imperfect dyad symmetry and the 21 bp repeat elements in the HCMV major IE promoter/regulatory region and mediates repression of HCMV IE gene expression. This strongly suggests that YY1 plays an important role in regulating HCMV expression in non-permissive cells.

The goal of the application is to annotate text and link it to relevant content, especially from the Linked Open Data (LOD) community and from the Ontos knowledge base. The paper describes two use cases and highlights the main functionality of the application.
An Analog-to-Digital Converter (1953)

A shaft position to binary number converter suitable for use as an input device for a digital computer is described. The basic component of the converter is a binary mechanical revolution counter having an output in the form of voltages or pulses on parallel lines representing, in the binary number system, the quantity stored in the counter. Ambiguities are eliminated by a novel method of internal switching. The effects of backlash are discussed and shown to be negligible.

Centralised Diagnostics of Electronic and Electric Equipment in Vehicles, Engine Lighting Equipment Testing (2007)

This paper proposes a diagnostic method that deals with obtaining diagnostic information on parts of engine systems. The focus of the research is on momentary state of engine lighting equipment "all ok" and "candle fault". The final diagnostic system should recognize "cable fault" and "transformer fault" in addition. Today's diagnostic systems used in vehicles are based on separate diagnostic subsystems for each electronic or electric device. The basic idea of the project is to develop a centralized diagnostic method to cover all functional systems. The proposed method would expedite the overall testing time and bring other significant advantages such as savings on test equipment. The fundamental idea is that both electronic and electric devices in a vehicle have a relationship to communication control busses. Also each device can be described as an electrical consumer with its typical power consumption characteristics. Hence, the proposed diagnostic method is based on investigating transient profile on power lines of a tested device whilst changing its state from off to on. The short time Fourier transform (STFT) processing is then applied to analyze the gained signal. The analysis results evaluate the condition of the engine lighting equipment.
An estimate of the global distribution of radon emissions from the ocean (2004)

There is a need for improved estimates of the radon ( 222 Rn) flux density from the ocean for use in the modeling and interpretation of atmospheric radon in global climate and air pollution studies. We use a modification of a frequently used model of gas transfer to generate global predictions of ocean radon flux density for each month of the year (climate averaged) on a 192 by 94 global grid. Compared with the often‐used approximation of a constant radon flux from the ocean, the model's predictions indicate large variations over regions of the ocean (a factor of ten is not uncommon). For example, latitude bands near the equator and Southern Ocean are predicted to emit relatively high average radon flux compared with other latitude bands. The predicted annually‐averaged flux density from the ocean is 0.0382 mBq m −2 s −1 (0.00182 atoms cm −2 s −1 ), smaller than some commonly‐used estimates.

The Treasury Single Account (TSA) as an Instrument of Financial Prudence and Management: Prospects and Problems (2016)

The Treasury Single Account (TSA) was recently implemented fully in the Nigerian economy by the present government in order to ensure prudence and probity in the management of financial resources. With the TSA government expects to block all loopholes and leakages of financial resources of the government and also ensure a robust financial management system. The paper therefore provides the conceptual meaning of the TSA and also gives its expected benefits to the economy of Nigeria such as enhance system of financial management and control, unification of various Accounts of government, reduction of the costs of government borrowing and ensuring of optimum utilization of government financial resources. The paper also analyses the objectives of the TSA systems and its various Accounts such as TSA main account, Subsidiary Account, ZBAs, Transit and Imprest Account among others. The paper finally discusses the prospects of the TSA system and its challenges and concludes that the system requires political will, honesty and determination so as to overcome the various challenges identified in the paper in order to achieve the expected benefits of the system Keywords: Single treasury account, probity, financial prudence and accountability
Does practice make perfect? Part I: The relation between hospital volume and outcomes for selected diagnostic categories. (1984)

The effect of a greater volume of patients with similar conditions being treated at a hospital on the outcomes achieved is studied using a variety of categories of patients, 15 surgical and 2 medical, and involving 550,000 patients treated in over 1,200 nonfederal United States acute care hospitals. After demonstrating that there are significant differences in the outcomes of patients, taking into account patient health status, the authors examine the impact of being treated in a hospital with a high or low volume of similar patients. Strong and consistent evidence is found that high volume is associated with better outcomes for surgical patients, which supports regionalizing patient care by procedure. Two additional variables, relative difficulty of the procedure and risk level of the patients, are analyzed to determine whether they change the relationship between volume and outcome. Some evidence is found that low-volume hospitals are associated with the poorest outcome for low-risk surgical patients. The evidence for medical patients is weak and mixed. Possible alternative explanations for the observed findings for surgical and medical patients are discussed.
Narrowband interference rejection in OFDM via carrier interferometry spreading codes (2005)

Orthogonal frequency-division multiplexing (OFDM) has gained a great deal of attention lately and is considered as a strong candidate for many next-generation wireless communication systems. However, OFDM (in its current implementation) does not demonstrate robustness to narrowband interference. In our earlier work, we showed how carrier interferometry (CI) spreading codes may be applied to spread OFDM symbols over all N subcarriers - this allows OFDM to exploit frequency diversity and improve performance (without loss in throughput). In this paper, we show that, by spreading OFDM symbols over all N subcarriers via CI spreading codes, the resulting carrier interferometry OFDM (CI/OFDM) system is also capable of suppressing narrowband interference. Simulation results for OFDM, coded OFDM (COFDM), CI/OFDM, and coded CI/OFDM over additive white Gaussian noise and multipath fading channels confirm CI/OFDM's robustness to narrowband interference.

Intracellular Injection of cAMP Induces a Long-Term Reduction of Neuronal K <sup>+</sup> Currents (1988)

Intracellular signals that trigger long-term (24-hour) changes in membrane currents in identified neurons of Aplysia have been examined in order to understand the cellular mechanisms underlying long-term sensitization. Adenosine 3',5'-monophosphate (cAMP) was directly injected into individual sensory neurons to mimic the effects of sensitization training at the single cell level. Potassium currents of these cells were reduced 24 hours after injection of cAMP; these currents were similar to those reduced 24 hours after behavioral sensitization. These results suggest that cAMP is part of the intracellular signal that induces long-term sensitization in Aplysia.

A novel relative orientation feature for shape-based object recognition (2009)

We propose a novel relative orientation feature (ROF) to represent the contour or skeleton of a two-dimensional object. With the aid of ROF, the shapes of two objects with fine structures can be compared. Matching with ROF is invariant with respect to translation, rotation and scaling transforms. Experimental results on hand gesture recognition demonstrate the effectiveness and efficiency of ROF with the identification rate of 98% and the average computational time less than 0.45 ms/frame.
Electron trajectories in twisted electrostatic deflection yokes (1973)

A mathematical analysis is carried out for electron motion in a cylindrical electrostatic deflection yoke which is twisted around its axis and immersed in a uniform axial magnetic field to form a twisted focus projection and scanning (FPS) deflection system. The yoke has an arbitrary twist angle, and is a generalization of yokes with π/2 rad of twist recently used in FPS vidicons. New modes of operation are found which eliminate shading caused by off-normal beam landing at the target, while providing improved deflection sensitivity, increased resolution, and reduced power consumption in the focusing solenoid as compared with the untrusted shading-free mode previously reported by Schlesinger, Wagner, and Saldi [1]-[3]. The theoretical predictions are supported by data from experimental devices.
<i>In vitro</i> Inhibitory Activity of Soluble ICAM-1 for the Numbered Serotypes of Human Rhinovirus (1993)

We studied the antirhinovirus activity of soluble intercellular adhesion molecule-1 (sICAM-1) against all 100 numbered human rhinovirus (HRV) serotypes in human embryonic lung fibroblast (HEL) cells. sICAM-1 inhibited replication of 88 of 90 HRVs belonging to the major receptor group with 50% effective concentrations (EC 50 ) ranging from 0.1 to 41.1 μg ml −1 (~0.002 to 0.8 μM). No inhibition at 100 μg ml −1 (~2 μM) was observed for HRV belonging to the minor receptor group, type 87, and two serotypes of the major receptor group (types 23 and 25). Yield reduction assays done with five HRV serotypes in human adenoid expiants found that sICAM-1 had concentration-dependent inhibitory effects that correlated closely with the activity observed in HEL cells ( r 2 = 0.99, P < 0.001).
Wide band meander line antenna for wireless communication systems (2002)

O-Charts: Towards an effective toolkit for teaching time complexity (2015)

Scientists, business analysts, and others in a growing number of fields are trying to cope with the vast amount of data being generated. The lack of software that can efficiently process large data sets hinders insight into complex relationships. One of the most important concepts in learning how to construct efficient code is time complexity analysis with Big-O notation. Students often find time complexity difficult to learn and too abstract to apply in any meaningful way. Common instructional methods consist of a combination of mathematics and intuitive analysis which are often too cumbersome for practical application or cannot be extended to complex algorithms. Unfortunately, there are few tools available for teaching time complexity that students find concrete, straightforward, and applicable to real problems. In this paper, we present O-Charts, a first step in the development of a practical toolkit for teaching and applying time complexity analysis. O-Charts allow the systematic analysis of deeply nested loops where the use of control variables makes the number of executions difficult to define, calculate, and explain. We report initial results and our plans for future work.
Effects of Glutamine‐Supplemented Diets on Immunology of the Gut (1990)

Recent research developments have identified the gastrointestinal tract as the most metabolically active organ after surgical stress. In addition to fulfilling its role as an organ of digestion and absorption, the gut must maintain immunologic function in order to protect the host from invading pathogens. Central to the function of the intestinal immune system is the expression of secretory IgA, the most abundant immunoglobulin in external secretions. The synthesis and expression of IgA in secretions appear to be sensitive to dietary alteration and may be impaired after surgical stress. Data are presented suggesting that maintenance of gut mass and barrier function to bacteria via dietary manipulation may be essential to ensure host survival during critical illness.
Synthesis and electrochemical properties of LiNi0.5Mn1.5O4 as a 5 V cathode material for lithium ion batteries (2012)

LiNi0.5Mn1.5O4 as a 5 V cathode material for a lithium-ion battery was synthesized by solution evaporation process in this paper. Thermal gravimetric analysis of the precursor compounds was carried out. X-ray diffraction and scanning electron microscope were used for studying the structure and the morphology of the LiNi0.5Mn1.5O4 materials. Cyclic voltammograms and charge–discharge curves were obtained for presenting the electrochemical performances of LiNi0.5Mn1.5O4. Experimental results show that the discharge capacity and capacity retention of the LiNi0.5Mn1.5O4 prepared by solution evaporation process are superior to the LiNi0.5Mn1.5O4 obtained by melting salt method. The effects of different sintering temperatures on the electrochemical properties of the LiNi0.5Mn1.5O4 electrode materials synthesized by a solution evaporation process were also systematically investigated. With the raising of the sintering temperature, the size of the LiNi0.5Mn1.5O4 gradually increases, its crystallinity is enhanced and the surface morphology of grain is gradually neatened. Electrochemical test results show that the LiNi0.5Mn1.5O4 prepared at 800 °C has the best cycle reversibility, the highest discharge capacity and the optimal capacity retention.
[Psychosomatic resort clinic patients]. (1977)

The structure of patients' specific expectations as to their "rehabilitation cure" in a psychosomatic rehabilitation clinic is demonstrated by means of a statistical study over 100 patients. Thereafter a collective of 500 patients of such a clinic is discribed in detail as to symptoms complained, duration of symptoms, prognosis, and psychotherapeutic results. At last, a review is given following up the further development of 247 rehabilitation patients; this review is prooving the effectiveness of group psychotherapy in the treatment of these patients.
The Effect of Ethane-1-Hydroxy-1, 1-Diphosphonic Acid (EHDP) on Matrix Induced Ectopic Bone Formation (1978)

The effect of diphosphonates (EHDP) was studied on induced ectopic osteoneogenesis. Decalcified allogeneic bone matrix was implanted into the lumbar muscles in rabbits for an ectopic osteoinductor. The ectopic new bone formation was studied under continuous EHDP administration and after discontinuation of EHDP. Although there was no inhibitory effect of EHDP on the osteoinduction, the calcification of the new bone and the resorption of the implanted matrix was retarded. The induced "osteoid-like" tissue had an atypical structure with a small number of cells and a deficiency in collagen fiber bundles. There were also large fields of new cartilage formation. Thus remodelling and mineralization were inhibited under the influence of continuous administration of EHDP. After discontinuation of EHDP administration a recovery phase was observed which seemed to lead to the formation of a normal ossicle.
Predicting Bond Ratings Using Neural Networks: A Comparison with Logistic Regression (1997)

Bond rating agencies examine the financial outlook of a company and the characteristics of a bond issue and assign a rating that indicates an independent assessment of the degree of default risk associated with the firm’s bonds. Predicting this bond rating has been of interest to potential investors as well as to the firm. Prior research in this area has primarily relied upon traditional statistical methods to develop models with reasonably good prediction accuracy. This article utilizes a neural network approach to modeling the bond rating process in an attempt to increase the overall prediction accuracy of the models. A comparison is made to a more traditional logistic regression approach to classification prediction. The results indicate that the neural networks-based model performs significantly better than the logistic regression model for classifying a holdout sample of newly issued bonds in the 1990–92 period. A potential drawback to a neural network approach is a tendency to overfit the data which could negatively affect the model’s generalizability. This study carefully controls for overfitting and obtains significant improvement in bond rating prediction compared to the logistic regression approach. © 1997 by John Wiley & Sons, Ltd.
Fragile X Syndrome (1998)

Fragile X syndrome (MIM 30955) is among the most common of human single-gene disorders and is the leading cause of inherited mental retardation, with an estimated frequency of 1/2000 to 1/4000 individuals. It is inherited as an X-linked dominant disorder with reduced penetrance. Males and females can be affected; however, the degree of mental retardation is usually more severe in males.
Marijuana: Current Concepts† (2013)

Marijuana (cannabis) remains a controversial drug in the twenty-first century. This paper considers current research on use of Cannabis sativa and its constituents such as the cannabinoids. Topics reviewed include prevalence of cannabis (pot) use, other drugs consumed with pot, the endocannabinoid system, use of medicinal marijuana, medical adverse effects of cannabis, and psychiatric adverse effects of cannabis use. Treatment of cannabis withdrawal and dependence is difficult and remains mainly based on psychological therapy; current research on pharmacologic management of problems related to cannabis consumption is also considered. The potential role of specific cannabinoids for medical benefit will be revealed as the twenty-first century matures. However, potential dangerous adverse effects from smoking marijuana are well known and should be clearly taught to a public that is often confused by a media-driven, though false message and promise of benign pot consumption.
