In this paper, we treat with in-play classification of sports news photos as an instance of researches on more sophisticated search methods for large-scale photo news databases. We propose two methods to classify sports news photos into one of the given six sports categories and to discriminate in-play photos from not-in-play ones. One is the two-step method which classifies sports categories f...

1. Reference and definition The formulation of the “divided cell” algorithm as an approach to the study of the values of a function f (x, y) that is a product of two inhomogeneous linear forms on a lattice in R2 appears in E. S. Barnes, “The inhomogeneous minima of binary quadratic forms (IV)”, Acta Math. 92 (1954) 235–264. Although this is the fourth paper in a series, the first three were wri...

Two concerns in US education are shortages of qualified math and science teachers and the feminization of teaching. I draw on the National Education Longitudinal Study of 1988 to identify a common reason for the two phenomena. Controlling for self-selection by a propensity score matching estimator and the Heckit, I find that the rigid pay structure for teachers, rather than the pay level, appea...

Math anxiety has an important impact on mathematical development and performance. However, although math anxiety is supposed to be a transcultural trait, assessment instruments are scarce and are validated mainly for Western cultures so far. Therefore, we aimed at examining the transcultural generality of math anxiety by a thorough investigation of the validity of math anxiety assessment in Eas...

Welcome to this introductory tutorial on wavelet transforms. The wavelet transform is a relatively new concept (about 10 years old), but yet there are quite a few articles and books written on them. However, most of these books and articles are written by math people, for the other math people; still most of the math people don't know what the other math people are talking about (a math profess...

In a sample of undergraduate students, myopia was associated with higher Math and Total SAT score, and males had higher Math and Total SAT scores than females. The association between myopia and higher Math and Total SAT scores was significant only among males, and the gender differences in Math and Total SAT scores were significant only among allergic participants. There were also significant ...

Intra-tumor heterogeneity (ITH) is crucial in tumorigenesis and resistance to target therapy. Here, we used mutant-allele tumor heterogeneity (MATH) to measure ITH based on next-generation sequencing data and high MATH was proven as an independent risk prognostic factor in male CRC patients in both a training set of 284 colorectal cancer (CRC) patients with from The Cancer Genome Atlas (TCGA) a...

Social cognitive models examining academic and career outcomes emphasize constructs such as attitude, interest, and self-efficacy as key factors affecting students' pursuit of STEM (science, technology, engineering and math) courses and careers. The current research examines another under-researched component of social cognitive models: social support, and the relationship between this componen...

Das HORSCH Telemetriesystem dient der drahtlosen Wartung und Diagnose der Maschine sowie einem kontinuierlichen Datenaustausch zum Zwecke der Planung und Kontrolle. Dabei kommuniziert ein Telemetriemodul in der Maschine wahlweise über WLAN mit mobilen Endgeräten oder direkt über GSM mit Serverdiensten. Somit wird eine Vernetzung von Online-Diensten, Maschinen und mobilen Endgeräten erreicht.
