Aggressiveness attributed to violent video game play is typically studied as a function of the content features of the game. However, can interface features of the game also affect aggression? Guided by the General Aggression Model (GAM), we examine the controller type (gun replica vs. mouse) and screen size (large vs. small) as key technological aspects that may affect the state aggression of ...

Correlated response data arise often in biomedical studies. The generalized estimation equation (GEE) approach is widely used in regression analysis for such data. However, there are few methods available to check the adequacy of regression models in GEE. In this paper, a graphical method is proposed based on Cook and Weisberg's marginal model plot. A bootstrap method is applied to obtain the r...

Plasma shaping effects on temperature gradient-driven instabilities and geodesic acoustic oscillations are investigated with a gyrokinetic theory and a local magnetohydrodynamics equilibrium model. In specific, we focus on the effect of the elongation κ , including its radial derivative ( )( ) r r s ∂ ∂ = κ κ κ , in the large aspect ratio limit. An analytical formula of the dependence of the GA...

Bayesian network classifiers (BNC) have received considerable attention in machine learning field. Some special structure BNCs have been proposed and demonstrate promise performance. However, recent researches show that structure learning in BNs may lead to a non-negligible posterior problem, i.e, there might be many structures have similar posterior scores. In this paper, we propose a generali...

Abstract Secondary low frequency mode generation by energetic particle induced geodesic acoustic (EGAM) observed in LHD experiment is studied using nonlinear gyrokinetic theory. It found that the EGAM can be significantly higher than local (GAM) collisionality plasmas, and it decay into two GAMs as its approaches twice GAM frequency, a process analogous to well-known plasmon instability. The co...

Japanese sardines (Sardinops melanostictus) are environmentally sensitive pelagic fish. We investigated the effects of environmental factors on stock-recruitment (S-R) relationship S. melanostictus in Pacific Ocean from 1984 to 2018. modeled and analyzed recruitment using Ricker model, environment extension model (Ricker-E), generalized additive (GAM). Different numbers were added models for fi...

The Northwest Indian Ocean is a key fishing ground for China’s pelagic fisheries, with the purpleback flying squid being significant target. This study uses commercial logs of between 2015 and 2021, alongside seawater temperature its vertical difference within 0–200 m depth range, to construct generalized additive models (GAMs) gradient boosting tree (GBTs). These two are evaluated using cross-...

Adaptive Resonance theory was introduced by Grossberg to address the stability versus plasticity dilemma. That is, how can one design a learning system that is plastic enough to learn new information, and at the same time stable enough not to forget old, important information that it has already learned. In the past two decades a number of ART neural network architectures were introduced in the...

BACKGROUND Nutritional surveillance remains generally weak and early warning systems are needed in areas with high burden of acute under-nutrition. In order to enhance insight into nutritional surveillance, a community-based sentinel sites approach, known as the Listening Posts (LP) Project, was piloted in Burkina Faso by Action Contre la Faim (ACF). This paper presents ACF's experience with th...
