This study analyzed routine locations (activity spaces) of urban adolescents enrolled in a substance abuse treatment program to understand the relationship between their spatial lives and health outcomes such as substance use and mental health. Sixty-eight adolescents were interviewed and produced a list of 199 locations identified as most important, safe, and risky. A TwoStep Cluster analysis ...

Remarkable cardinals were introduced by Schindler, who showed that the existence of a remarkable cardinal is equiconsistent with the assertion that the theory of L(R) is absolute for proper forcing [Sch00]. Here, we study the indestructibility properties of remarkable cardinals. We show that if κ is remarkable, then there is a forcing extension in which the remarkability of κ becomes indestruct...

Metal hydride heat pump (MHHP for short) is a promising candidate among the many sorption heat pumps. To improve its performance, the alloys used in the system should be selected carefully. In this article, a new procedure was proposed for selection of pairing alloys according to the operation conditions of MHHP, which followed a twostep strategy. First several pairs of alloys feasible for work...

To capture the missed information in the standardized errors by parametric multivariate generalized autoregressive conditional heteroskedasticity (MV-GARCH) model, we propose a new semiparametric MV-GARCH (SM-GARCH) model. This SM-GARCH model is a twostep model: firstly estimating parametric MV-GARCH model, then using nonparametric skills to model the conditional covariance matrix of the standa...

Game analysis has an important role on the description of ‘what happens’ in competitions and should reach the ability to suggest new ways to enhance sport performances. In order to accomplish this goal is important that possible factors enables to influence these performances were considered. Quality of opposition is one of these factors. In this study, TwoStep Clusters analysis was used to cla...

In cryptography, quantum information processing can be used to do much more than just key distribution. Simple quantum transformations augmented with the ability to store qubits in a quantum memory are the building blocks of a protocol allowing two parties to communicate secretly by encoding/decoding the exchanged message directly through quantum means, without the need to establish a secret en...

Numerous NLP tasks rely on clustering or community detection algorithms. For many of these tasks, the solutions are disjoint, and the relevant evaluation metrics assume nonoverlapping clusters. In contrast, the relatively recent task of abstractive community detection (ACD) results in overlapping clusters of sentences. ACD is a sub-task of an abstractive summarization system and represents a tw...

Sentence simplification reduces semantic complexity to benefit people with language impairments. Previous simplification studies on the sentence level and word level have achieved promising results but also meet great challenges. For sentencelevel studies, sentences after simplification are fluent but sometimes are not really simplified. For word-level studies, words are simplified but also hav...

In this paper, we investigate the transmission of H.263 video sequences over wireless networks with error recovery provided by a twostep adaptive hybrid ARQ scheme using RS codes. Each video frame is divided into data packets for transmission. For each packet transmission, by using a simple table-driven approach, the best RS code is selected from a given set of codes to minimize the transmissio...
