The neuronal stem cell of the olfactory epithelium

Reviews and evaluates psychosocial treatments for attention deficit hyperactivity disorder (ADHD) in children and adolescents according to Task Force Criteria (Lonigan, Elbert, & Johnson, this issue). It is concluded that behavioral parent training and behavioral interventions in the classroom meet criteria for well-established treatments. Cognitive interventions do not meet criteria for well-established or probably efficacious treatments. Issues regarding the evaluative process are discussed and future directions for psychosocial treatment for ADHD are outlined.     

General circular permutation layout

In thegeneral circular permutation layout problem there are two concentric circles,C _in andC _out. There are a set ofn inner terminals onC _in and a set ofn outer terminals onC _out: terminalsi onC _in and _i onC _out are to be connected by means of a wire, where 1 i n. All wires must be realized in the interior ofC _out. Each wire can intersectC _in at most once and at mostK wires, for a fixedK, can pass between two adjacent inner terminals. A linear-time algorithm for obtaining a planar homotopy (single-layer realization) of an arbitrary instance of the general circular permutation layout problem, forK 0, is proposed. Previously,K = 1 has been studied. In this paper the algorithm is also extended to a more general problem, in which the number of wires allowed to pass between each pair of adjacent terminals onC _in may be different from pair to pair.The work of R.

Multi-phase toughened epoxy with poly(ether sulphone) and carboxyl-terminated butadiene-acrylonitrile rubber

The structure and properties of ternary blends of epoxy with poly(ether sulphone) (PES) and carboxyl-terminated butadiene-acrylonitrile rubber (CTBN) have been investigated. In these blends, the phase separation occurs in two stages: a macrophase separation during mixing and a microphase separation during curing. At low PES compositions, the PES-rich spherical domains are dispersed. With increasing PES composition, a co-continuous structure develops and, eventually, the phases are inverted. Regardless of structure change, the modulus and yield stress changes with composition just follow the simple rule of mixtures. However, the fracture toughness of these blends exhibits a synergistic effect. Among the various compositions, 55 weight ratio of CTBN to PES exhibited the maximum toughness, which was 140% larger than that calculated from the rule of mixtures. The synergism is believed to be due to the bridging by the PES-rich phase followed by a lowering of the yield stress. The lowering of the yield stress can enlarge the process zone size and the amount of plastic dilatation of the matrix.     

Fuzzy Tree Clustering Algorithm with Mobile Data Collectors in Wireless Sensor Networks

In recent years, the need to deploy Wireless Sensor Networks increases in different applications. Several studies have been proposed to demonstrate the importance to use Mobile Data Collectors (MDC) in Wireless sensor Networks. The main goal of this paper is to reduce the energy consumption of sensor nodes and to extend the network lifetime. In this paper, we propose to construct a Minimum Spanning tree, we design a fuzzy Cluster Head election system to elect the best sensor nodes as Cluster Heads, considering two input parameters, namely the weight of Sensor Nodes (WoSN) and the State of Sensor Node Locations (SoSNLoc). To extend the network lifetime, a subset of MDCs travels the area to gather the sensed data from nodes instead of sending them directly to the Base Station (BS) in a single hop or multi-hop manner. The BS is located at the center of the area which will be divided into sub-regions, one for each MDC. According to their positions, each CH will belong to a specific region, and then will be visited by the corresponding MDC. Simulation results show the effectiveness of our proposed algorithm in terms of energy consumption and network lifetime in comparison with other ones.

     

The orthorhombic-to-tetragonal phase transition in YBa2(Cu1−xFex)3O7−y

The phase transition YBa₂(Cu_1–x Fe _x )₃O_7–y (0x0.05) prepared through solid-state reaction was studied with X-ray diffraction analysis and optical microscope. It was found that the orthorhombic-to-tetragonal phase change was induced between x=0.02 and x=0.03 by X-ray diffraction. The phase transition was also identified by the disappearance of striations in plate-like grains under polarized light. The microstructures of the specimens with compositions of x=0.01 and x=0.02 showed faint striation images. It is considered that a mixture of the orthorhombic and tetragonal phase exists in these compositions.     

What you like in design use to correct bad-smells

Over the past decades, many techniques and tools have been developed to support maintenance activities in order to improve software quality. One of the most efficient ones is software refactoring to eliminate bad-smells. A majority of existing work propose “standard” refactoring solutions that can be applied by hand for each kind of defect. However, it is difficult to prove or ensure the generality of these solutions to any kind of bad-smells or software codes. In this paper, we propose an approach to correct bad-smells using well-designed code. We use genetic algorithms to generate correction solutions defined as a combination of refactoring operations that maximize, as much as possible, the similarity between the corrected bad-smells and examples of well-designed code. We report the results of an evaluation of our approach using four open-source projects. Our proposal achieved high correction scores by fixing the majority of expected bad-smells.

Outcomes of patients with end‐stage renal disease (ESRD) under chronic hemodialysis requiring continuous renal replacement therapy (CRRT) and patients without ESRD in acute kidney injury requiring CRRT: A single‐center study

In most continuous renal replacement therapy (CRRT) studies, end‐stage renal disease (ESRD) patients were excluded and the outcomes of patients with ESRD treated with chronic hemodialysis (HD) were unknown. The purposes of this study were to (1) evaluate short‐term patient survival and (2) compare the survival of conventional HD patients needing CRRT with the survival of non‐ ESRD patients in acute kidney injury (AKI) requiring CRRT. We evaluated adults (>18 years) requiring CRRT who were treated in the intensive care unit (ICU) at Kosin University Gospel Hospital from January 1, 2009 to December 31, 2010. A total of 100 (24 ESRD, 76 non‐ESRD) patients underwent CRRT during the study period. Patients were divided into two major groups: patients with ESRD requiring chronic dialysis and patients without ESRD (non‐ESRD) with AKI. We compared the survival of conventional HD patients requiring CRRT with the survival of non‐ ESRD patients in AKI requiring CRRT. For non‐ESRD patients, the 90‐day survival rate was 41.6%. For ESRD patients, the 90‐day survival rate was 55.3%. Multivariate Cox proportional hazards analyses demonstrated that conventional HD was not a significant predictor of mortality (hazard ratio [HR]: 0.334, 95% confidence interval [CI]: 0.063–1.763, P = 0.196), after adjustment for age, gender, presence of sepsis, APACHE score, use of vasoactive drugs, number of organ failures, ultrafiltration rate, and arterial pH. The survival rates of non‐ESRD and ESRD patients requiring CRRT did not differ; ESRD with conventional HD patients may be not a significant predictor of mortality.
