Inference on factor graphs with loops with the standard forwardbackward algorithm, can give unpredictible results as messages can travel indefinitely in the system with no guarantee on convergence. We apply the exact method of cutset conditioning to Factor Graphs with loops starting from a fully developed three-variable example and providing comments and suggestions for distributed implementati...

Recent advances in shopper insights reveal that consumers rarely “shop” the entire store. On average, shoppers’ paths only cover about one-third of the areas in a grocery store and hence are unexposed to the majority of products in the store. Given that shoppers typically use physical products in the store as an external memory cue, encouraging shoppers to travel more of the store may increase ...

Simple spatial interaction models of human mobility based on physical laws have been used extensively in the social, biological, and physical sciences, and in the study of the human dynamics underlying the spread of disease. Recent analyses of commuting patterns and travel behavior in high-income countries have led to the suggestion that these models are highly generalizable, and as a result, g...

The importance of household structure on mobility patterns in urban areas has been revealed by many studies. However, data for this type of analysis are not always available even though the need for taking into account family structure may be extremely important in the explanation of differences in travel behavior, namely in the comparative analysis of different socioeconomic or cultural contex...

Travellers are at risk of a diverse range of environmental and infectious conditions, some of which may affect the eyes and lead to blindness in severe cases. Travel-related ocular infections include onchocerciasis, leishmaniasis, cysticercosis, trachoma, dengue, loiasis, and leptospirosis. The travel medicine adviser should also recognise other hazards encountered during travel which may adver...

In traditional traffic assignment procedure, each traffic analysis zone is represented by one point in its geometric center which is connected to the network by several connectors. Results of studies show that different connector patterns would result up to 10% change in estimated volume and up to 20% change in total travel time. Also the different patterns of connectors can change the priority...

introduction: it has been known for a long time in the french-speaking, but not the english-speaking literature that travel can exacerbate pre-existing psychosis. the purpose of this article was to review the literature on this subject and present recommendations for prevention. methods: for this narrative review of the literature on travel risks in individuals with pre-existing psychosis, appr...

Introduction: There has been significant growth in international tourism from South-East Asia. Travel medicine services are still quite limited in this region. Few data exists on the knowledge, attitudes and practices of travelers from South-East Asia regarding the prevention of travel-related health risks. The present study aimed to characterize the travel t...

Introduction: Immigrants to the United States who return home to visit friends and relatives (VFRs) have high rates of travel-related infections. The data on VFR utilization of pre-travel health care is inadequate. The objective of this study was to describe the travel patterns and adherence to pre-travel recommendations of VFRs.Methods: This retrospectiv...
