An allergic reaction to mosquitoes can result in severe or abnormal local or systemic reactions such as anaphylaxis, angioedema, and general urticarial or wheezing. The aim of this review is to provide information on mosquito saliva allergens that can support the production of highly specific recombinant saliva allergens. In particular, candidate allergens of mosquitoes that are well suited to the ecology of mosquitoes that occur mainly in East Asia will be identified and introduced. By doing so, the diagnosis and treatment of patients with severe sensitivity to mosquito allergy will be improved by predicting the characteristics of East Asian mosquito allergy, presenting the future direction of production of recombinant allergens, and understanding the difference between East and West.

For the past 18 months the NASPA Journal Editorial Board has been engaged in an ongoing conversation about the future direction of the Journal. Among the issues we have discussed are: What should comprise the content of the Journal?, How do we decide when or if we will move the Journal to an electronic format?, What do our members want in the Journal?, and What type of scholarship should we be publishing? The last question — What type of scholarship should we be publishing? — led to an energetic conversation within the Editorial Board.

Abstract This paper describes the status of the API project to develop and maintain Risk-Based Inspection (RBI) methodology for application within the petroleum and chemical industry. The original project has now moved from a “development” phase into an “implement and improve” phase. This paper describes the essential features of API RBI, the most recent enhancements, software features, the future direction for the project, and some user experiences. This paper also describes the acceptance of RBI by various API codes and standards, by jurisdictional authorities, and it also describes the development of an API recommended practice on RBI (API RP 580) as well as the development of an ASME standard on RBI.

The Hellenic Air Force (HAF) operates both EMB-145 and EMB-135 LR versions of Embraer aircraft, used in surveillance and civil missions respectively. These aircraft are equipped with the same version of Rolls Royce, AE 3007 turbofan engine. This study aims to quantify and compare the life consumption rate of this engine when installed in each of the two aircraft variants. Two typical missions, one for each variant, were constructed based on mission profile data dictated by the aircraft commanders. For each mission profile segment, corresponding engine data were matched out of the engine recordings archives held by the Hellenic Air Force. The life consumption rate was based on the Low Cycle Fatigue (LCF) and creep cumulative detrimental effect on the rotor blades of the 1st High-Pressure Turbine stage. For the LCF, the rainflow method was used to determine the respective loading cycles, whereas the Larson - Miller parameter method was used to determine the consumed life fractions due to creep. The main conclusion of the study was that the engine when installed in the EMB-145 military variant, is much more loaded. Despite the fact absolute life consumption values could hide a great level of uncertainty, the comparative outcomes wherein errors are, to a certain extent, cancelled out, could be used as a rule of thumb when monitoring engine life consumption rates.

SummaryImage-based deep learning systems, such as convolutional neural networks (CNNs), have recently been applied to cell classification, producing impressive results; however, application of CNNs has been confined to classification of the current cell state from the image. Here, we focused on cell movement where current and/or past cell shape can influence the future cell fate. We demonstrate that CNNs prospectively predicted the future direction of cell movement with high accuracy from a single image patch of a cell at a certain time. Furthermore, by visualizing the image features that were learned by the CNNs, we could identify morphological features, e.g., the protrusions and trailing edge that have been experimentally reported to determine the direction of cell movement. Our results indicate that CNNs have the potential to predict the future cell fate from current cell shape, and can be used to automatically identify those morphological features that influence future cell fate.
