This paper addresses two concerns with the state of the art in network revenue management with dependent demands. The first concern is that the basic attraction model (BAM), of which the multinomial logit (MNL) model is a special case, tends to overestimate demand recapture in practice. The second concern is that the choice based deterministic linear program, currently in use to derive heuristi...

Current therapies for high-grade gliomas extend survival only modestly. The glioma microenvironment, including glioma-associated microglia/macrophages (GAM), is a potential therapeutic target. The microglia/macrophage cytokine CSF1 and its receptor CSF1R are overexpressed in human high-grade gliomas. To determine whether the other known CSF1R ligand IL34 is expressed in gliomas, we examined exp...

BACKGROUND Hu County is a serious hemorrhagic fever with renal syndrome (HFRS) epidemic area, with notable fluctuation of the HFRS epidemic in recent years. This study aimed to explore the optimal model for HFRS epidemic prediction in Hu. METHODS Three models were constructed and compared, including a generalized linear model (GLM), a generalized additive model (GAM), and a principal componen...

Generalized additive models are useful in finding predictor-response relationships in many kinds of data without using a specific model. They combine the ability to explore many nonparametric relationships simultaneously with the distributional flexibility of generalized linear models. The approach often brings to light nonlinear dependency structures in your data. This paper discusses an examp...

Research has consistently demonstrated a link between certain personality disorders (PDs) and increased rates of aggression and violence. At present, understanding of the mechanisms that underlie this relationship is limited. This study was designed to examine the contention (Gilbert & Daffern, 2011) that the application of a contemporary psychological aggression theory, the General Aggression ...

In this work, targeting, e.g., future generation cellular, microwave-links, or optical fiber systems, we propose a new geometric shaping design for golden angle modulation (GAM) based on a (double) truncated Gaussian input distribution. The design improves the mutual information (MI), and the peak-toaverage power ratio, over the full signal-to-noise ratio (SNR) range relative to two key GAM sch...

This paper introduces a formally specified design of a compositional generic agent model (GAM). This agent model abstracts from specific application domains; it provides a unified formal definition of a model for weak agenthood. It can be (re)used as a template or pattern for a large variety of agent types and application domain types. The compositional development method DESIRE was used to des...

The forest temperature is one key parameter in the models developed for providing early fire risk alerts. The satellite remote sensing data are the best way to obtain this parameter both regionally and globally. This study proposes an approach to obtain Forest Surface Temperature (FST) by means of Terra-ASTER (Advanced Spaceborne Thermal Emission and Reflectance Radiometer) multiband algorithms...
