Academic evaluations such as tenure/promotion applications and society fellowship nominations rely heavily on bibliometric measures of each candidate’s research impact, including their research citations. This article first reviews existing evaluation criteria such as the h-index and<em> q</em>-most-citations, and then proposes a weighted w-index which minimizes shortcomings in existing single-number measures. The w-index consists of three factors<span style="white-space:nowrap;">&#8212;</span>3 most cited first-author publications, 3 most cited publications as the corresponding/last author, and 3 additional most cited publications as a co-author, but does not allow double counting of these publications. 展开更多

In this paper, a semi-parametric regression model with an adaptive LASSO penalty imposed on both the linear and the nonlinear components of the mode is considered. The model is rewritten so that a signed-rank technique can be used for estimation. The nonlinear part consists of a covariate that enters the model nonlinearly via an unknown function that is estimated using Bsplines. The author shows that the resulting estimator is consistent under heavy-tailed distributions and asymptotic normality results are given. Monte Carlo simulations as well as practical applications are studied to assess the validity of the proposed estimation method. 展开更多

Over the past 50 years,crown asymmetry of forest trees has been evaluated through several indices constructed from the perspective of projected crown shape or displacement but often on an ad hoc basis to address specifi c objectives related to tree growth and competition,stand dynamics,stem form,crown structure and treefall risks.Although sharing some similarities,these indices are largely incoherent and non-comparable as they diff er not only in the scale but also in the direction of their values in indicating the degree of crown asymmetry.As the fi rst attempt at devising normative measures of crown asymmetry,we adopted a relative scale between 0 for perfect symmetry and 1 for extreme asymmetry.Five existing crown asymmetry indices(CAIs)were brought onto this relative scale after necessary modifi cations.Eight new CAIs were adapted from measures of circularity for digital images in computer graphics,indices of income inequality in economics,and a bilateral symmetry indicator in plant leaf morphology.The performances of the 13 CAIs were compared over diff erent numbers of measured crown radii for 30 projected crowns of mature Eucalyptus pilularis trees through benchmarking statistics and rank order correlation analysis.For each CAI,the index value based on the full measurement of 36 evenly spaced radii of a projected crown was taken as the true value in the benchmarking process.The index(CAI 13)adapted from the simple bilateral symmetry measure proved to be the least biased and most precise.Its performance was closely followed by that of three other CAIs.The minimum number of crown radii that is needed to provide at least an indicative measure of crown asymmetry is four.For more accurate and consistent measures,at least 6 or 8 crown radii are needed.The range of variability in crown morphology of the trees under investigation also needs to be taken into consideration.Although the CAIs are from projected crown radii,they can be readily extended to individual tree crown metrics that are now commonly extracted from 展开更多

Text Rank is a popular tool for obtaining words or phrases that are important for many Natural Language Processing (NLP) tasks. This paper presents a practical approach for Text Rank domain specific using Field Association (FA) words. We present the keyphrase separation technique not for a single document, although for a particular domain. The former builds a specific domain field. The second collects a list of ideal FA terms and compounds FA terms from the specific domain that are considered to be contender keyword phrases. Therefore, we combine two-word node weights and field tree relationships into a new approach to generate keyphrases from a particular domain. Studies using the changed approach to extract key phrases demonstrate that the latest techniques including FA terms are stronger than the others that use normal words and its precise words reach 90%. 展开更多

This paper generalizes the factorization theorem of Gouveia,Parrilo and Thomas to a broader class of convex sets.Given a general convex set,the authors define a slack operator associated to the set and its polar according to whether the convex set is full dimensional,whether it is a translated cone and whether it contains lines.The authors strengthen the condition of a cone lift by requiring not only the convex set is the image of an affine slice of a given closed convex cone,but also its recession cone is the image of the linear slice of the closed convex cone.The authors show that the generalized lift of a convex set can also be characterized by the cone factorization of a properly defined slack operator. 展开更多

The primary objective of this pilot study was to evaluate the impact of social rank on the well-being of gestating sows housed in a free access stall-pen housing environment. At d 30 post-breeding, 32 multiparous crossbred sows in groups of 4 were allocated to a stall-pen housing environment. Blood samples were taken at gestational d 30 (before mixing) and d 31 (24-h post-mixing), and then again at d 89 and 110;whereas, sow behavior was recorded at gestational d 30, 66, 87, and 102. Social rank was determined based on aggressive encounters, dyadic fighting wins and losses, and displacements between sows by 48-h post-mixing. At d 31 (post-mixing), regardless of social rank, total WBC decreased and, lymphocyte counts increased, but % change was more significant among the subordinates than dominants. The same trend occurred with neutrophil chemotaxis increased more in subordinates, but ConA-induced lymphocyte proliferation increased more in dominants, whereas LPS-induced lymphocyte proliferation was reduced among dominants. Sow behavior was differentially affected by social rank and time-periods or gestational day, with subordinates spending more time sitting and drinking, especially during time-periods 1, 3, and 4. Dominants displayed more oral-nasal-facial behaviors during mid-gestation but more sham-chew during time-period 2, which included feeding time. Social rank also influenced the percentage of time sows spent in either the stall or pen area, with subordinates in stalls and dominants in pen. These data imply that social rank differentially influences physiology and behavior of dry sows housed in a free access stall-pen environment. More specifically, the location of the dominant sow, time of day, and activity may influence when and where the subordinates spend their time within this housing system. 展开更多

Let G be a graph of order n with vertex set V(G) = {v1, v2,…, vn}. the adjacency matrix of G is an n × n matrix A(G) = (aij)n×n, where aij is the number edges joining vi and vj in G. The eigenvalues λ1, λ2, λ3,…, λn, of A(G) are said to be the eigenvalues of the graph G and to form the spectrum of this graph. The number of nonzero eigenvalues and zero eigenvalues in the spectrum of G are called rank and nullity of the graph G, and are denoted by r(G) and η(G), respectively. It follows from the definitions that r(G) + η(G) = n. In this paper, by using the operation of multiplication of vertices, a characterization for graph G with pendant vertices and r(G) = 7 is shown, and then a characterization for graph G with pendant vertices and r(G) less than or equal to 7 is shown. 展开更多

In this paper, we are interested to find the most sensitive parameter, local and global stability of ovarian tumor growth model. For sensitivity analysis, we use Latin Hypercube Sampling (LHS) method to generate sample points and Partial Rank Correlation Coefficient (PRCC) method, uses those sample points to find out which parameters are important for the model. Based on our findings, we suggest some treatment strategies. We investigate the sensitivity of the parameters for tumor volume, <em>y</em>, cell nutrient density, <em>Q</em> and maximum tumor size, <em>ymax</em>. We also use Scatter Plot method using LHS samples to show the consistency of the results obtained by using PRCC. Moreover, we discuss the qualitative analysis of ovarian tumor growth model investigating the local and global stability. 展开更多
