The timely fixing of bugs is important to ensure software quality. In Open Source Software (OSS) development, behaviors of stakeholders impact the bug fixing process, especially the different stages respectively. However, most of the existing studies on impact factors of bug fixing time usually treat bug fixing process as a whole, while neglecting the particularity at its different stages. Igno...

‘Who can fix this bug?’ is an important question in bug triage to “accurately” assign developers to bug reports. To address this question, recent research treats it as a optimizing recommendation accuracy problem and proposes a solution that is essentially an instance of content-based recommendation (CBR). However, CBR is well-known to cause over-specialization, recommending only the types of b...

We recently synthesized all stereoisomers of 1,10-bisaboladien-3-ol and 10,11-epoxy-1-bisabolen-3-ol, including three stink bug pheromones, via a rhodium-catalyzed asymmetric addition of trimethylaluminum to diastereomeric mixtures of cyclohex-2-enones. However, yields of trans isomers were low, and scaling reactions using expensive catalysts were cumbersome. Now we describe a new synthesis of ...

Researchers have proposed a number of tools for automatic bug localization. Given a program and a description of the failure, such tools pinpoint a set of statements that are most likely to contain the bug. Evaluating bug localization tools is a difficult task because existing benchmarks are limited in size of subjects and number of bugs. In this paper we present iBugs, an approach that automat...

Virtual platform checkpointing is a technology by which the entire state of the software and hardware of an executing system is captured. Checkpoints can be used for many different purposes during software (and hardware) development. Here, we focus on how they are used to transport bugs between bug reporters and developers. Compared to describing the system state and steps needed to reproduce a...

Bug tracking systems play a central role in software development since they allow users and developers to submit and discuss bugs and new features. To better understand information and communication needs in bug tracking, we analysed what questions are asked in bug reports. We sampled 600 bug reports from the MOZILLA and ECLIPSE projects and located 947 questions in the reports. Next, we used a...

This manuscript presents an approach for studying the abundance of bug fix patterns. Bug fix patterns capture the knowledge on how to fix bugs, they are essential building blocks for research areas such as bug fix recommendation and automatic repair. In this paper, we focus on the problem of the accurate measurement of bug fix pattern abundance: how to reliably tell that one pattern is more com...

Soybean is an important food crop, and insect integrated pest management (IPM) is critical to the sustainability of this production system. In recent years, the introduction into the United States of the kudzu bug currently identified as Megacopta cribraria (F.), poses a threat to soybean production. The kudzu bug was first discovered in the state of Georgia, U.S. in 2009 and since then has spr...

Since 1988, cucurbit crops, particularly watermelon, cantaloupe, and squash, grown in Oklahoma and Texas have experienced devastating losses from cucurbit yellow vine disease (CYVD), caused by the phloem-limited bacterium Serratia marcescens Bizio. Squash bug, Anasa tristis (De Geer), is a putative vector of the pathogen. In 2000-2001, overwintering populations of squash bug collected from DeLe...

In the southeast United States, a field of peanuts, Arachis hypogaea L., is often closely associated with a field of cotton, Gossypium hirsutum L. The objective of this 4-yr on-farm study was to examine and compare the spatiotemporal patterns and dispersal of the southern green stink bug, Nezara viridula L., and the brown stink bug, Euschistus servus (Say), in six of these peanut-cotton farmsca...
