Special purpose automatic programming for hidden surface elimination (1982)

In many applications of three dimensional computer graphics, the appearance of the same scene must be computed repeatedly for many different positions of the viewer. This paper concerns a scheme for exploiting this property of an application for the purpose of improving the efficiency of the hidden surface computation. The scheme involves a kind of automatic programming: for each scene to be considered, a different special purpose program is automatically constructed. The special purpose program then takes the position of the viewer as input, and generates a suitable description of the scene with hidden surfaces removed as output. Since the special purpose program has a very limited task to perform - it is adapted to handling just one scene - it can be much faster than any general purpose algorithm would be for the same scene. The paper describes a method by which special purpose programs for hidden surface elimination can be constructed in a fully automatic manner. The method has been implemented, and results of experiments are given.
Vaccination with a feline immunodeficiency virus multiepitopic peptide induces cell-mediated and humoral immune responses in cats, but does not confer protection (1997)

Cats were immunized with a 46-residue multiepitopic synthetic peptide of feline immunodeficiency virus (FIV) comprising immunodominant epitopes present in the third variable domain of the envelope glycoprotein, transmembrane glycoprotein (TM), and p24 Gag core protein, using Quil A as an adjuvant. All vaccinated cats developed a humoral response which recognized the synthetic peptide immunogen and the intact viral core and envelope proteins. A FIV Gag- and Env-specific effector cytotoxic T-lymphocyte response was also detected in the peripheral blood of vaccinated cats, which peaked at week 30. This response appeared to be major histocompatibility complex restricted. Epitope mapping studies revealed that both the cellular and humoral immune responses were directed principally to a peptide within the TM glycoprotein, CNQNQFFCK. However, vaccination did not confer protection when cats were challenged with the Petaluma isolate of FIV at week 35.
Gender, social background and sexual attitudes among Chinese students (2007)

Chinese society is changing rapidly. As a result of the political and economic reforms of the 'socialist market economy', for example, people have more choices than before. To examine current attitudes to sexual behaviour and marriage, 1100 university students from different parts of China were asked to talk about their views on marriage and choosing a marriage partner, and to describe their own sexual behaviours. Views about 'male superiority' in marriage, for age, education and height persisted, especially for women. Overall, attitudes to sexual behaviours were less open then in the West. However, young people from the cities with educated/professional parents showed more liberal attitudes than those from rural backgrounds. While some attitudes are changing, evidence concerning behaviour change is not so clear. There are important implications for the HIV/AIDS awareness programmes and sex education.

A fuzzy iterative approach for determination of current waveform for switched reluctance motors using a torque sharing function at positive and negative torque production regions (2005)

This paper deals with a fundamental control issue in switched reluctance motor (SRM) drives - the torque ripples. Normally, torque ripple minimization is achieved by using a look-up table, i.e., the look-up table uses stored magnetic characteristics to provide the reference current for some specified torque. A number of techniques for the generation of reference current profiles that minimize the torque ripples have been suggested. But, because of highly nonlinear characteristics of the SRM, all these schemes are not fully successful. Our work deals with a novel algorithm for generation of current waveforms by modulation of the reference current pattern of the two-phase-on scheme with torque sharing functions at both positive and negative torque production regions by means of a multiplying factor for minimizing the torque ripple. This multiplying factor is computed with the aid of fuzzy logic, which is well suited to compensate for the nonlinearities of the system. Performance of the proposed strategy is verified by simulation.
Cursor-on-Target Control for Semi-autonomous UAS (2008)

The research presented in this paper focuses on developing and evaluating the concept of a Cursor-on-Target controller for semi-autonomous unmanned aircraft systems (UAS). The proposed Cursor-on-Target operator interface and control laws provide an extremely intuitive means for an operator (who doesn’t have to be an aircraft pilot) to maneuver a UAS with minimum workload. The operator is able to easily control the vehicle without taking eyes off of the sensor display and without having to think in terms of control surface deflections. Autonomous UAS control reduces operator workload; however, real-time information exchange often requires an operator to be able to relay decision changes to the UAS. The goal of this research is to develop a Cursor-on-Target controller to enable the operator to guide the UAS with minimal workload even during high task phases of flight. Then, an operator’s ability to track a moving target using the Cursor-on-Target controller is evaluated using an operator-in-the-loop simulation and a proposed UAS Handling Qualities Rating Scale. The results and lessons learned after having several operators perform tracking tasks using the proposed control system and rating scale is presented.
Wellness Dimensions Relate to Happiness in Children and Adolescents (2010)

Abstract This paper describes the results of a study designed to explore factors in children and adolescents that contribute to happiness, and to contribute to the reliability and validity of the Child and Adolescent Wellness Scale (CAWS). Rooted in resilience research and the philosophy of positive psychology, the CAWS is a recently developed self-report instrument that provides psychologists with a means of evaluating the competencies of children and adolescents across 10 domains associated with well-being. Surveys from a sample of 281 middle and high school students were collected to investigate the instrument's technical properties and its relationship with a measure of happiness or life satisfaction. The CAWS evidenced strong internal consistency reliability. Student CAWS scores were highly correlated (r = .71) with self-report ratings from the Multidimensional Students' Life Satisfaction Survey, providing criterion validity and suggesting that the CAWS dimensions are associated with happiness in youth. Potential applications of the CAWS as a tool to promote positive mental health and future research directions are discussed. Keywords: POSITIVE MENTAL HEALTHSOCIAL-EMOTIONAL ASSESSMENTWELLNESS
An efficient technique for human verification using finger stripes geometry (2007)

This study attempts to improve the performance of person verification by finger stripes geometry, which is an efficient, simple, fast, easy to handle and cost effective compared with other biometric human verification technique. Finger stripe geometry is a new biometric type in verification process. This finger stripe based verification consists of two main attributes, feature extraction by image processing and feature learning by ANN (Artificial Neural Network). The Distance Based Nearest Neighbor Algorithm, which shows greater accuracy than NN is also applied here. Using this approach, experimental result provides, Total Success Rate (TSR) is 98.79%, False Acceptance Rate (FAR) is 3.21% and False Rejection Rate (FRR) is 0%. Since the proposed method requires very small computational time, the practical implementation requirement for a large number of person verification is possible.
Passivity Enforcement via Perturbation of Hamiltonian Matrices (2004)

This paper presents a new technique for the passivity enforcement of linear time-invariant multiport systems in state-space form. This technique is based on a study of the spectral properties of related Hamiltonian matrices. The formulation is applicable in case the system input-output transfer function is in admittance, impedance, hybrid, or scattering form. A standard test for passivity is first performed by checking the existence of imaginary eigenvalues of the associated Hamiltonian matrix. In the presence of imaginary eigenvalues the system is not passive. In such a case, a new result based on first-order perturbation theory is presented for the precise characterization of the frequency bands where passivity violations occur. This characterization is then used for the design of an iterative perturbation scheme of the state matrices, aimed at the displacement of the imaginary eigenvalues of the Hamiltonian matrix. The result is an effective algorithm leading to the compensation of the passivity violations. This procedure is very efficient when the passivity violations are small, so that first-order perturbation is applicable. Several examples illustrate and validate the procedure.
Anti-cydo-oxygenase Agents and Asthma (1983)

Aspirin inhibits cyclo-oxygenase by an irreversible time-dependent process of inactivation; this mechanism appears to be responsible for precipitation of asthmatic attacks in about 5%-10% of adult asthmatic patients. Besides aspirin, all other cyclo-oxygenase inhibitors induce bronchoconstriction in sensitive patients, while nonsteroidal anti-inflammatory drugs without anti-cyclo-oxygenase activity can be taken by the same patients with impunity. While aspirin-sensitive patients should avoid the potential for adverse reactions, there are rare reports of bronchodilation following ingestion of aspirin and aspirinlike drugs.
Hybrid Cooperative Beamforming and Jamming for Physical-Layer Security of Two-Way Relay Networks (2013)

In this paper, we propose a hybrid cooperative beamforming and jamming scheme to enhance the physical-layer security of a single-antenna-equipped two-way relay network in the presence of an eavesdropper. The basic idea is that in both cooperative transmission phases, some intermediate nodes help to relay signals to the legitimate destination adopting distributed beamforming, while the remaining nodes jam the eavesdropper, simultaneously, which takes the data transmissions in both phases under protection. Two different schemes are proposed, with and without the instantaneous channel state information of the eavesdropper, respectively, and both are subjected to the more practical individual power constraint of each cooperative node. Under the general channel model, it is shown that both problems can be transformed into a semi-definite programming (SDP) problem with an additional rank-1 constraint. A current state of the art technique for handling such a problem is the semi-definite relaxation (SDR) and randomization techniques. In this paper, however, we propose a penalty function method incorporating the rank-1 constraint into the objective function. Although the so-obtained problem is not convex, we develop an efficient iterative algorithm to solve it. Each iteration is a convex SDP problem, thus it can be efficiently solved using the interior point method. When the channels are reciprocal such as in TDD mode, we show that the problems become second-order convex cone programming ones. Numerical evaluation results are provided and analyzed to show the properties and efficiency of the proposed hybrid security scheme, and also demonstrate that our optimization algorithms outperform the SDR technique.
Fingerprint Minutiae Matching without Global Alignment Using Local Structures (2008)

This paper presents a method of minutiae based fingerprint matching that is robust to deformations and does not do fingerprint alignment. It concentrates on comparing rotation and translation invariant local structures defined by minutiae point and its neighboring minutiae points. Then the collection of most probable correspondences of matched minutiae is found. Finally, the local structures of higher order are validated. All three steps are completely rotation and translation invariant, robust to nonlinear deformations and do not use any fingerprint alignment. Experimental results on publicly available as well as internal databases show an improved performance of the proposed method in comparison with the traditional minutiae based algorithms that perform fingerprint registration.
Magnetic Measurements on Iron Powders (1944)

CLONAL ANALYSIS OF CELL LINEAGE PATTERNS IN PLANT DEVELOPMENT (1987)

Somatic sectors induced by ionizing radiation provide a great deal of information about cell lineage patterns in both plants and animals. Somatic sectors arise when the dominant allele of a mutation with a visible, cell‐autonomous phenotype is lost as a result of a deletion or somatic recombination. In addition to marking the fate of cells in a primordium at different stages of development and in different tissues, this technique also provides information about the distribution, orientation, rate, and duration of cell division. The technology and underlying assumptions of this method, termed clonal analysis , are described in this paper.
Evidence shows staff ratios can work (2013)

Supporters of mandatory staffing ratios argue that they are essential to ensure safe patient care, and can point to states in the United States and Australia where they have been implemented successfully. Ratios are complex and are likely to face political resistance in the UK.
Systematic evaluation of CNN on land cover classification from remotely sensed images (2018)

In using the convolutional neural network (CNN) for classification, there is a set of hyperparameters available for the configuration purpose. This study aims to validate the effectiveness of the CNN architecture, i.e. AlexNet on land cover classification, based on four remotely sensed land-use land-cover (LULC) datasets. In addition to the evaluation of the impact of a range of parameters in the evaluation tests, the influence of a set of hyperparameters on the classification performance will be assessed. The parameters include the epoch values, batch size, convolutional filter size and input image size. Thus, a set of experiments were conducted to specify the effectiveness of the selected parameters. We first explore the number of epochs under several selected batch size values. The impact of the first layer kernel size of the convolutional filters also was evaluated. Moreover, testing assorted sizes of the input images provided insight of the influence of the size of the convolutional filters and the image sizes. To generalize the validation, four remote sensing datasets, AID, RDS, UCMerced and RSCCN7, which have different land coverage and are publicly available, were used in the experiments. These datasets have a wide diversity of input data, such as the number of classes, amount of labelled data and texture patterns. A specifically-designed, interactive, deep-learning GPU training platform for image classification (Nvidia Digit) was employed in the experiments. It has shown efficiency in both training, evaluation and testing. These results provide opportunities toward better classification performance in various applications, such as hyperspectral multi-temporal agricultural LULC.

Experimental data in this paper verify Ausman’s solution. A correlation is attempted, and the design procedure given herein is based upon a combination of the Ausman theoretical method and these experimental studies.
Address allocation scheme of wireless sensor networks based on IPv6 (2009)

The Wireless Sensor Network (WSN) is one of the core technologies to form the future networks. A WSN is typically composed of numerous tiny energy-constrained sensor nodes with limited information processing and data storage capabilities, thus, the energy-efficient strategy is the key issue in designing protocols for WSN. All IPv6-based addressing is suitable for the seamless integration between WSN and IPv6. However, the length of IPv6 address is too long for WSN, and the energy cost becomes a key problem in the use of all IPv6-based addressing. We propose an improved self-organized addressing scheme with simplified IPv6 address format which is designed for intra-WSN communication, and the corresponding address allocation, stateless autoconfiguration, redirection method are presented. This scheme realizes dynamic addressing, and stateless address autoconfiguration. The simulation result demonstrates that the scheme reaches the expected effect of saving energy and prolonging the lifespan of the sensor networks.
Statistics of maximum entropy IID noise given its cumulants (2003)

Given a finite set of moments or cumulants, the problem of finding the probability density function that maximizes the differential entropy is treated. Following the MAXENT approach of E.T. Jaynes (1982), a Lagrange multiplier optimization problem for the probability density of the independent, identically distributed (i.i.d.) noise, which can be solved analytically with the help of gamma and Bessel functions, is arrived at.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Differential Regulation of HIC1 Target Genes by CtBP and NuRD, via an Acetylation/SUMOylation Switch, in Quiescent versus Proliferating Cells (2010)

The tumor suppressor gene HIC1 encodes a transcriptional repressor involved in regulatory loops modulating P53-dependent and E2F1-dependent cell survival, growth control, and stress responses. Despite its importance, few HIC1 corepressors and target genes have been characterized thus far. Using a yeast two-hybrid approach, we identify MTA1, a subunit of the NuRD complex, as a new HIC1 corepressor. This interaction is regulated by two competitive posttranslational modifications of HIC1 at lysine 314, promotion by SUMOylation, and inhibition by acetylation. Consistent with the role of HIC1 in growth control, we demonstrate that HIC1/MTA1 complexes bind on two new target genes, Cyclin D1 and p57KIP2 in quiescent but not in growing WI38 cells. In addition, HIC1/MTA1 and HIC1/CtBP complexes differentially bind on two mutually exclusive HIC1 binding sites (HiRE) on the SIRT1 promoter. SIRT1 transcriptional activation induced by short-term serum starvation coincides with loss of occupancy of the distal sites by HIC1/MTA1 and HIC1/CtBP. Upon longer starvation, both complexes are found but on a newly identified proximal HiRE that is evolutionarily conserved and specifically enriched with repressive histone marks. Our results decipher a mechanistic link between two competitive posttranslational modifications of HIC1 and corepressor recruitment to specific genes, leading to growth control.

Antineutrophil cytoplasmic antibodies in Wegener's granulomatosis (1998)

The prevalence of antineutrophil cytoplasmic antibodies (ANCA) was studied in 12 children with Wegener's granulomatosis. The serum samples were taken in the active phase of disease and were screened for ANCA by indirect immunofluorescence with normal neutrophils and enzyme linked immunosorbent assay (ELISA) using crude neutrophil extract, proteinase 3, myeloperoxidase, cathepsin G, lactoferrin, and elastase as antigens. Of these 12 patients, 10 wre positive for ANCA in the active phase of their illness, and they showed a predominantly cytoplasmic ANCA staining pattern on indirect immunofluorescence. There were high titres of ANCA directed against crude neutrophil extract, proteinase 3, myeloperoxidase, and cathepsin G. IgM isotypes occurred as commonly as IgG isotypes. Therefore, screening for ANCA is usually but not invariably positive in children with Wegener's granulomatosis. Specific diagnosis still relies on clinical and pathological features, and the value of ANCA in the diagnosis of paediatric Wegener's granulomatosis requires further study.
Clinical efficacy of capecitabine and cyclophosphamide (XC) in patients with metastatic breast cancer. (2011)

Combined low-dose therapy of oral capecitabine (Xeloda) and cyclophosphamide (XC) has been demonstrated to be useful for long-term control of lesions in patients with metastatic breast cancer (MBC) and is aimed at symptomatic alleviation and prolongation of survival. Here, a retrospective review was conducted of MBC patients administered XC at the Okayama University Hospital (OUH), to evaluate responses to XC, adverse events and time to progression (TTP). Twenty patients with MBC received XC between 2006 and 2009. With the exception of 2 elderly patients who were over the age of 70 at the initial examination, all of the patients had received prior treatment with an anthracycline and/or a taxane. No complete response (CR) cases were observed, but partial response (PR) was achieved in 6 patients (30%) and SD in 9 (45%), of whom 5 (20%) sustained SD status for >12 months. The median TTP was 6 months (range:3-27 mo.). Three patients developed Grade 3 adverse events (diarrhea, nausea and stomatitis), but no other patients developed adverse reactions causing interruption of the therapy. XC was safe even in previously treated and elderly MBC patients;moreover, it yielded remarkable clinical responses.
An integrated approach towards designing an embedded wireless monitoring and access control system using RFID and MMS technologies (2013)

This paper proposes and implements an embedded wireless access control system using a combination of RFID and MMS technologies. The RFID and MMS sections are each controlled by a cost effective AT89C52 microcontroller. The microcontroller in RFID section is responsible for reading the user tag information, searching the read information in a memory chip for a match and triggering the microcontroller in MMS section accordingly while the microcontroller in MMS section is responsible for issuing AT commands to Quectel M33 cellular engine for capturing the user image and transferring the image to owner mobile phone using MMS, a multimedia service of GSM network. A decision is finally made by the owner either to grant or deny access to the user by sending a text message to the access control system.
