Sub-Channel and Power Allocation for Non-Orthogonal Multiple Access Relay Networks With Amplify-and-Forward Protocol

In this paper, we study the resource allocation problem for a single-cell non-orthogonal multiple access (NOMA) relay network where an OFDM amplify-and-forward relay allocates the spectrum and power resources to the source–destination (SD) pairs. We aim to optimize the resource allocation to maximize the average sum-rate. The optimal approach requires an exhaustive search, leading to an NP-hard problem. To solve this problem, we propose two efficient many-to-many two-sided SD pair-subchannel matching algorithms, in which the SD pairs and sub-channels are considered as two sets of players chasing their own interests. The proposed algorithms can provide a sub-optimal solution to this resource allocation problem in affordable time. Both the static matching algorithm and the dynamic matching algorithm converge to a pair-wise stable matching after a limited number of iterations. Simulation results show that the capacity of both proposed algorithms in the NOMA scheme significantly outperforms the conventional orthogonal multiple access scheme. The proposed matching algorithms in NOMA scheme also achieve a better user-fairness performance than the conventional orthogonal multiple access.
Mechanism of T-cell help in the immune response to soluble protein antigens II. Reconstitution of primary and secondary in vitro immune responses to dinitrophenyl-carrier conjugates by T-cell-replacing factor

Spleen cells of dinitrophenyl keyhole limpet hemocyanin (DNPKLH) primed and boosted mice produced a nonantigen-specific helper factor upon in vitro challenge with DNPKLH. This helper factor displays all of the biological characteristics so far described for TRF produced by allogeneic or Concanavalin A stimulation of mouse spleen cells. It restores the primary anti-SRBC response in nude spleen cultures following the same kinetics of action as T-cell-replacing factor (TRF). Conversely, TRF restores the primary in vitro immune response of nude spleen cultures to DNPKLH. TRF also restores the secondary anti-hapten IgG response of T-cell-deprived spleen cell cultures derived from DNPKLH primed and boosted mice. Here the need for carrier specificity is fully overcome. The data therefore suggest that TRF, as a nonantigen- specific maturation signal, is involved in the primary and secondary immune responses to both particulate and soluble antigens.
Recent Activity of the Badu‐Longwei Segment, Guguan‐Xiangong Fault in Southern Liupanshan, Constrained by Rhythmic Sediment Lithology and Geomorphic Characteristics

This study's objective was to investigate the Guguan‐Xiangong Fault, which lies in the southern Liupanshan area, through satellite image interpretation and field observations. Guguan‐Xiangong Fault is divided into five subsegments; among these, the Badu‐Longwei segment has been the most recently active. The geomorphic features of the Badu‐Longwei segment are clearly displayed, including multiple high fault scarps with fresh bedrock free faces. There is significant evidence for Holocene activity of the three fault sections, located in Renhuashu, Tianjiagou, and Xinjiecun respectively. The three sections feature distinct episodic deposition and fault scratches. Based on 14C‐dating and field observations on the three fault sections, two or more paleoearthquakes across the Badu‐Longwei fault segment are ascertained, between 5874±116 and 5430±140 a BP, and after 2037±83 a BP respectively. The Badu‐Longwei segment of the Guguan‐Xiangong Fault is preliminarily extrapolated as the seismogenic structure of the 600 A.D. Qin‐Long earthquake.
High dose intravenous methylprednisolone in treatment of recessive osteopetrosis.

Cartlidge and Rutter have provided useful data relating serum albumin concentration to gestation and discuss its poor correlation with clinical oedema. ' Their view, however, that 'hypoalbuminaemia of prematurity' is a 'normal not a pathological finding' is debatable. A biochemical or clinical finding that is consistently associated with prematurity is not necessarily normal' and may indeed be undesirable. In this study the authors have examined only one clinical aspect of hypoalbuminaemia, oedema; yet low serum albumin concentration may have diverse effectsfor instance, on drug and bilirubin binding and toxicity. Currently, we are analysing the relation between clinical outcome and plasma albumin concentration measured in over 4000 samples during a longitudinal study of 932 infants. Preliminary multiple regression analysis has reaffirmed the strong association between hypoalbuminaemia and respiratory disease, even after adjustment for gestation. Low plasma albumin concentration in this circumstance cannot be regarded as 'normal' and probably reflects excessive losses-for example, into alveoli-and the adverse effect of severe disease or suboptimal nutrition on protein synthesis by an immature liver. Yet sick infants must have comprised an appreciable proportion of the low gestation sample investigated by Cartlidge and Rutter. These workers contend 'that measurement of serum albumin concentrations in preterm infants, either routinely or in the presence of oedema, is of little use in their management'. This conclusion might be misinterpreted. A low plasma albumin concentration may be used as a marker for the high risk neonate, may influence the interpretation of other biochemical findings, and may warrant intervention in its own right. Albumin estimation is cheap and, I believe, should not be abandoned as a routine investigation in very low birthweight infants in the neonatal period.
Association Between Primary Care Practice Characteristics and Emergency Department Use in a Medicaid Managed Care Organization

Background:Many patients use emergency departments (EDs) for primary care. Previous studies have found that patient characteristics affect ED utilization. However, such studies have led to few policy changes. Objectives:We sought to determine whether Medicaid patients’ ED use is associated with characteristics of their primary care practices. Research Design:This was a cohort study. Subjects:A total of 57,850 patients, assigned to 353 primary care practices affiliated with a Medicaid HMO, were included. Measures:Predictor variables were characteristics of primary care practices, which were measured by visiting each practice. The outcome variable was ED use adjusted for patient characteristics. Results:On average, patients made 0.80 ED visits/person/yr. Patients from practices with more than 12 evening hours/wk used the ED 20% less than patients from practices without evening hours. A higher ratio of the number of active patients per clinician-hour of practice time was associated with more ED use. When more Medicaid patients were in a practice, these patients used the ED more frequently. Other factors associated with ED use included equipment for the care of asthma and presence of nurse practitioners and physician assistants. Discussion:Modifiable characteristics of primary care practices were associated with ED use. Because the observational design of this study does not allow definitive conclusions about causality, future studies should include intervention trials to determine whether changing practice characteristics can reduce ED use. Conclusions:Improving primary care access and scope of services may reduce ED use. Focusing on systems issues rather than patient characteristics may be a more productive strategy to improve appropriate use of emergency medical care.
Discovery of Gait Anomalies from Motion Sensor Data

A tool for discovery of gait anomalies of elderly from motion sensor data is proposed. The gait of the user is captured with the motion capture system, which consists of tags attached to the body and sensors situated in the apartment. Position of the tags is acquired by the sensors and the resulting time series of position coordinates are analyzed with dynamic time warping and machine learning algorithms in order to identify the specific gait anomaly. We designed medically oriented features for training a machine learning classifier that classifies the user’s gait into: i) normal, ii) with hemiplegia, iii) with Parkinson’s disease, iv) with pain in the back and v) with pain in the leg. Experimental results show that the proposed tool is usable for discovery of gait anomalies
I get by with a little help from my family and friends: adolescents' support for diabetes care.

Evaluated and compared the support provided by family members and friends for adolescents' diabetes care. Family and friend support also were examined in relation to other measures of social support, to demographic variables (age, gender, duration of diabetes) and to adherence. Using a structured interview, 74 adolescents with diabetes described the ways that family members and friends provided support for diabetes management (insulin shots, blood glucose monitoring, eating proper meals, exercise), and for helping them to "feel good about their diabetes. " Families provided more support than friends for three management tasks (insulin injections, blood glucose monitoring, meals); this support was largely instrumental. In contrast, friends provided more emotional support for diabetes than families. Greater family support was related to younger age, shorter disease duration, and better treatment adherence. Implications of the findings include encouraging parents to remain involved in adolescents' treatment management, and involving peers as supportive companions for meals and exercise.
Performance Evaluation of an Active Learning System to Improve Students Self-Learning and Concentration

In our previous work, it has been shown that the students can improve the learning process by using smartphones. The professors of the university cannot provide the information to satisfy all students because the quantity of knowledge of each student attending a lecture is different. Therefore, for the lectures of a higher level than intermediate level, the students should study the learning materials by themselves. In the previous work, we presented an interactive learning process in order to improve the students learning motivation and the self-learning time. To improve the progress speed of a lecture, we proposed an Active Learning System (ALS). Also, we introduced a procedure for Self-learning by adding some functions in order to improve the efficiency of the Self-learning. In this paper, we performed experimental evaluation of our ALS. The results showed that the proposed ALS can improve student self-learning and concentration.
Germinal Matrix Hemorrhage: Intraventricular Hemorrhage in Very-Low-Birth-Weight Infants The Independent Role of Inherited Thrombophilia

Background and Purpose— The etiology of germinal matrix hemorrhage–intraventricular hemorrhage (GMH-IVH) is multifactorial and the role of genetic polymorphisms is unclear. The aim of this prospective study was to evaluate prothrombotic genetic mutations as independent risk factors for the development of all grades of GMH-IVH in very-low-birth-weight infants. Methods— The presence of both factor V Leiden and prothrombin gain-of-function gene mutations were prospectively assessed in 106 very-low-birth-weight infants. Infants with GMH-IVH were compared to those without GMH-IVH according to genetic and clinical characteristics. Results— Twenty-two out of 106 infants had GMH-IVH develop (20.7%). Infants with GMH-IVH had significantly lower gestational ages and birth weights. In the multivariate Poisson regression model, the prevalence of GMH-IVH appeared to be inversely related to gestational age, with a risk ratio of 0.83 (95% CI, 0.72–0.97; P=0.02) per week. Risk ratio of GMH-IVH for carriers of either prothrombotic mutation was 2.65 (95% CI, 1.23–5.72; P=0.01), similar to the risk ratio associated with need for resuscitation at birth (2.30; 95% CI, 1.02–5.18; P=0.04). Conclusions— Very-low-birth-weight infants who are carriers for either prothrombotic mutations are at increased risk for development of GMH-IVH. Genetic factors act as independent risk factors of the same magnitude as other known risk factors.
Déterminants et conséquences du dégoût physique et moral : du jugement stéréotypé à la déshumanisation

Le degout est une emotion au cœur de notre vie individuelle et collective. A la fois « gardien » du corps et de l’esprit, un degout physique se distingue d’un degout moral. Dans une premiere recherche (Etude 1), nous avons examine les caracteristiques de ces deux types de degout a partir de recits d’experiences emotionnelles vecues. Une analyse de contenu thematique ainsi qu’une analyse lexicale informatisee de ces recits (logiciel ALCESTE) ont mis en evidence que le degout physique passe par les sens et emerge lors de situations ou l’individu est « acteur » de ce qui se passe alors que le degout moral, moins pur car mele de colere et de tristesse, serait ressenti apres observation et evaluation d’une situation de transgression morale (ex. trahison). Le second objectif de cette these etait d’examiner les consequences du degout physique et moral sur la perception stereotypee et deshumanisee d’autrui (Dasgupta et al., 2009 ; Harris & Fiske, 2006 ; Tiedens & Linton, 2001). Deux recherches (Etudes 2 et 3) nous ont permis de mettre en evidence qu’une compatibilite entre le degout incident (i.e. induit independamment de la cible de l’evaluation) et le degout integral chronique (i.e. suscite par l’appartenance groupale de la cible) conduit les individus a baser davantage leur jugement sur leurs stereotypes. De plus, l’etude 3 suggere de considerer dans ce processus, outre le degout chronique, le degout integral episodique (i.e. evoque par le comportement de la cible ; Bodenhausen, 1993). Dans une quatrieme etude, nous avons examine l’impact d’une compatibilite entre le degout chronique et episodique sur la perception stereotypee. Les resultats montrent que cette compatibilite conduit a une stereotypie plus importante lorsque la cible appartient a un groupe protege (i.e. obese). En outre, cette recherche met au jour le role du degout comme facteur de deshumanisation, mais aussi l’effet d’une emotion positive de sympathie dans le processus de « re-humanisation ». L’ensemble de ce travail souligne le role cle des emotions integrales dans la perception sociale et laisse apparaitre la necessite de s’interesser au degout et a ses effets afin de comprendre et de lutter contre l’exclusion sociale dont certains groupes sont victimes
Determining Effective Elasticity Parameters of Microstuctured Materials

In this paper we study homogenization of elastic materials with a periodic microstructure. Homogenization is a tool to determine effective macroscopic material laws for microstructured materials that are in a statistical sense periodic on the microscale. For the computations Composite Finite Elements (CFE), tailored to geometrically complicated shapes, are used in combination with appropriate multigrid solvers. We consider representative volume elements constituting geometrically periodic media and a suitable set of microscopic simulations on them to determine an effective elasticity tensor. For this purpose, we impose unit macroscopic deformations on the cell geometry and compute the microscopic displacements and an average stress. Using sufficiently many unit deformations, the effective (usually anisotropic) elasticity tensor of the cell can be determined. In this paper we present the algorithmic building blocks for implementing these ‘cell problems’ using CFE, periodic boundary conditions and a multigrid solver. We apply this in case of a scalar model problem and linearized elasticity. Furthermore, we present a method to determine whether the underlying material property is orthotropic, and if so, with respect to which axes.
The structure of memory meets memory for structure in linguistic cognition

Title of dissertation: THE STRUCTURE OF MEMORY MEETS MEMORY FOR STRUCTURE IN LINGUISTIC COGNITION Matthew Webb Wagers Doctor of Philosophy, 2008 Dissertation directed by: Professor Colin Phillips Department of Linguistics This dissertation is concerned with the problem of how structured linguistic representations interact with the architecture of human memory. Much recent work has attempted to unify real-time linguistic memory with a general content-addressable architecture (Lewis & Vasishth, 2005; McElree, 2006). Because grammatical principles and constraints are strongly relational in nature, and linguistic representation hierarchical, this kind of architecture is not well suited to restricting the search of memory to grammatically-licensed constituents alone. This dissertation investigates under what conditions real-time language comprehension is grammatically accurate. Two kinds of grammatical dependencies were examined in reading time and speeded grammaticality experiments: subject-verb agreement licensing in agreement attraction configurations (“The runners who the driver wave to .”; Kimball & Aissen, 1971, Bock & Miller, 1991), and active completion of wh-dependencies. We develop a simple formal model of agreement attraction in an associative memory that makes accurate predictions across different structures. We conclude that dependencies that can only be licensed exclusively retrospectively, by searching the memory to generate candidate analyses, are the most prone to grammatical infidelity. The exception may be retrospective searches with especially strong contextual restrictions, as in reflexive anaphora. However dependencies that can be licensed principally by a prospective search, like wh-dependencies or backwards anaphora, are highly grammatically accurate.

Discover layered structure in ultrasound images with a joint sparse representation model

Deconvolution can improve the resolution of ultrasound system since the effect of point spread function can be removed. Traditional methods carry out the deconvolution line by line, so the neighborhood information are unused. A joint sparse model is proposed in this work to discover layered structure in ultrasound images. The model joints the axial deconvolution with a sparse lateral constraint. The model was tested on simulation and real data, and results support the enhanced performance in terms of resolution.
Evaluation Set for Slovak News Information Retrieval

This work proposes an information retrieval evaluation set for the Slovak language. A set of 80 queries written in the natural language is given together with the set of relevant documents. The document set contains 3980 newspaper articles sorted into 6 categories. Each document in the result set is manually annotated for relevancy with its corresponding query. The evaluation set is mostly compatible with the Cranfield test collection using the same methodology for queries and annotation of relevancy. In addition to that it provides annotation for document title, author, publication date and category that can be used for evaluation of automatic document clustering and categorization.
Designing an interface for real-time and embedded DEVS

In this work, we are proposing a hardware-in-the-loop model-driven method to develop real-time and embedded applications based on DEVS (Discrete Event Systems Specification) formalism. This approach combines the advantages of a simulation-based approach with the rigor of a formal methodology. This framework can be used to develop embedded applications incrementally, and integrate simulation models with hardware components seamlessly. We have defined structural modifications to the current DEVS abstract simulator, allowing for integration with hardware devices, using external ports of the model and adding hardware control mechanisms. The use of this methodology provides model continuity from the early stages of model design to embedding it on the target. We have discussed the details of implementation of the proposed technique on E-CD++ (a DEVS based toolkit).
Immunofluorescence detection of Cryptosporidium oocysts in fecal smears

An indirect fluorescent antibody (IFA) procedure was developed for the detection of Cryptosporidium sp. oocysts in human, nonhuman primate, and bovine fecal smears. The procedure, which takes about 90 min to perform, involves the use of a rabbit antiserum against Cryptosporidium oocysts isolated from dairy cattle. Cross-specificity testing of the IFA method revealed no reactivity with yeasts, various amoebae, Giardia lamblia, Chilomastix sp. , or Blastocystis sp. and only very weak cross-reactivity with coccidian oocysts of other genera. IFA detection of oocysts in human and nonhuman primate fecal smears was far more sensitive than was dimethyl sulfoxide-carbolfuchsin staining. Moreover, IFA detection was comparable in sensitivity to auramine O staining with samples of high oocyst concentration and somewhat more sensitive than auramine O with samples containing relatively few oocysts. The IFA procedure may be useful in the clinical diagnosis of human and animal cryptosporidiosis and also in the detection of oocysts in environmental samples.
The CS Freiburg Team: Playing Robotic Soccer Based on an Explicit World Model

Robotic soccer is an ideal task to demonstrate new techniques and explore new problems. Moreover, problems and solutions can easily be communicated because soccer is a well-known game. Our intention in building a robotic soccer team and participating in RoboCup-98 was, first, to demonstrate the usefulness of the self-localization methods we have developed. Second, we wanted to show that playing soccer based on an explicit world model is much more effective than other methods. Third, we intended to explore the problem of building and maintaining a global team world model. As has been demonstrated by the performance of our team, we were successful with the first two points. Moreover, robotic soccer gave us the opportunity to study problems in distributed, cooperative sensing.
Object manipulation in 3d space by two cone-shaped finger robots based on finger-thumb opposability without object sensing

There are many difficulties in dexterous object manipulation by multi-fingered hands, due to redundant degree-of-freedom of the entire system and uncertainties in interaction with the object. In this paper, however, 3D object manipulation without any external sensors are attempted. Under the assumption of point contact without rolling, the object position and orientation are computed in relative sense and used as the feedback for object manipulation. Overall system dynamics including two cone-shaped finger robots and an arbitrary object is modeled, and the closed-loop system stability is analyzed based with the proposed controllers for stable grasping and object position/orientation control. In order to validate the proposed method, dynamic simulation is conducted, and showed complacent results.
