Identifying and predicting key features to support bug reporting

Published: August 2019

AbstractBug reports are the primary means through which developers triage and fix bugs. To achieve this effectively, bug reports need to clearly describe those features that are important for the developers. However, previous studies have found that reporters do not always provide such features. Therefore, we first perform an exploratory study to identify the key features that reporters frequently miss in their initial bug report submissions. Then, we propose an approach that predicts whether reporters should provide certain key features to ensure a good bug report. A case study of the bug reports for Camel, Derby, Wicket, Firefox, and Thunderbird projects shows that Steps to Reproduce, Test Case, Code Example, Stack Trace, and Expected Behavior are the additional features that reporters most often omit from their initial bug report submissions. We also find that these features significantly affect the bug‐fixing process. On the basis of our findings, we build and evaluate classification models using four different text‐classification techniques to predict key features by leveraging historical bug‐fixing knowledge. The evaluation results show that our models can effectively predict the key features. Our comparative study of different text‐classification techniques shows that naïve Bayes multinomial (NBM) outperforms other techniques. Our findings can benefit reporters to improve the contents of bug reports.
A cross‐scale refined damage evolution analysis of large commercial aircraft crashing into a nuclear power plant

SummarySince the 9/11 attacks, whether nuclear power plants (NPPs) can withstand the malicious impact of large commercial aircraft has become a question that must be considered in the design phase. Refined model and fine‐scale element reflect more accurately the failure procedure and behaviour. However, due to the exceedingly complex structure of NPP, the traditional meshing method requires a substantial number of geometric operations involving point, line, area, and volume, leading to a tedious modelling process and very high computational costs, as well as making it difficult to modify and optimize the model. This paper combines the scaled boundary finite element method with the octree technique to refine nuclear engineering damage evolution analysis and establish a refined numerical model of the Generation III+ NPP, considering the detailed equipment hatch, air intake, and internal steel containment vessel structures. Subsequently, the refined damage evolution analysis of a large commercial aircraft crashing into an NPP was developed. The mesh size sensitivity, impact region shape comparison, and the influence of different impact heights were discussed. The results indicate that the cross‐scale refined meshing and analysis method provides a high‐quality discrete grid with fewer elements. Furthermore, this method is highly flexible, more accurately simulating the damage evolution and gradual destruction process. We recommend future structural optimization for the air intake and conducting detailed analyses at this location. The cross‐scale analysis method presented in this paper enables a rapid, refined simulation of a malicious impact by a large commercial aircraft. Additionally, it provides technical support for future studies of the responses of NPPs' internal structures, systems, and equipment under extreme earthquake and other disaster conditions.

Published: August 2019

A robust generic classification for Amaryllidaceae has remained elusive mainly due to the lack of unequivocal diagnostic characters, a consequence of highly canalized variation and a deeply reticulated evolutionary history. A consensus classification is proposed here, based on recent molecular phylogenetic studies, morphological and cytogenetic variation, and accounting for secondary criteria of classification, such as nomenclatural stability. Using the latest sutribal classification of Hippeastreae (Hippeastrinae and Traubiinae) as a foundation, we propose the recognition of six genera, namely Eremolirion gen. nov., Hippeastrum, Phycella s.l., Rhodolirium s.str., Traubia, and Zephyranthes s.l. A subgeneric classification is suggested for Hippeastrum and Zephyranthes to denote putative subclades. In Hippeastrum, we recognize H. subg. Hippeastrum and H. subg. Tocantinia. In Zephyranthes, Z. subg. Eithea, Z. subg. Habranthus, Z. subg. Myostemma (= core Rhodophiala clade), Z. subg. Neorhodophiala subg. nov., and Z. subg. Zephyranthes are recognized. Descriptions, synonymy, taxonomic keys, and new combinations are provided for each genus and subgenus.
A componovation perspective of innovation in emerging markets: Evidence from Indian organizations
Authors: Dutta Swarup K. , Snehvrat Saurav 
Published: August 2019

AbstractIn todays market landscape firms can effectively compete without the benefit of resource advantages, proprietary technology, or market power but by being more aligned towards creative combination and responsive innovation. This study approaches the concept of componovation from the composition based view (CBV) developed by Luo and Child. The CBV emphasizes how firms with ordinary resource endowments can achieve outstanding results through the creative use of open resources and unique integrating capabilities that result in an enhanced speed and a value‐price ratio that are well suited to large numbers of mass market consumers. Thus componovation is a new approach aimed at innovation in emerging markets.

AbstractWe examined microplastic concentrations, size distributions, and polymer types in surface waters of a northern European dimictic lake. Two sampling methods, a pump sieving water onto filters with different pore sizes (20, 100, and 300 µm) and a common manta trawl (333 µm), were utilized to sample surface water from 12 sites at the vicinity of potential sources for microplastic emissions. The number and polymer types of microplastics in the samples were determined with optical microscopy and μFTIR spectroscopy. The average concentrations were 0.27 ± 0.18 (mean ± SD) microplastics/m3 in manta trawled samples and 1.8 ± 2.3 (>300 μm), 12 ± 17 (100–300 μm) and 155 ± 73 (20–100 μm) microplastics/m3 in pump filtered samples. The majority (64%) of the identified microplastics (n = 168) were fibers, and the rest were fragments. Materials were identified as polymers commonly used in consumer products, such as polyethylene, polypropylene, and polyethylene terephthalate. Microplastic concentrations were high near the discharge pipe of a wastewater treatment plant, harbors, and snow dumping site.Practitioner points

Samples were taken with a manta trawl (333 μm) and a pump filtration system (300/100/20 μm)

With pump filtration, small 20–300 μm particles were more common than >300 μm particles

The average concentration of manta trawled samples was 0.27 ± 0.18 (mean ± SD) microplastics/m3

FTIR analysis revealed PE, PP, PET, and PAN to be the most common polymers

AbstractThis book is about Singapore’s development into a city in which water and vegetation, along with associated environmental, technical, social and political aspects have been harnessed and cultivated into a livable sustainable way of life. It is also a story about a unique and thoroughgoing approach to large-scale and potentially transferable water sustainability, within largely urbanized circumstances, which can be achieved, along with complementary roles of environmental conservation, ecology, public open-space management and the greening of buildings, together with infrastructural improvements.
Water Resources and Sustainability
Authors: Rowe Peter G. , Hee Limin 
Published: August 2019

AbstractIn addition to ‘green and clean’ in the service of national identity, equality and attractiveness, sustainability of Singapore with regard to water supply and use is of strategic national concern. Indeed, it is expected to achieve this by 2061 when Singapore’s remaining water agreement with neighboring Malaysia will end, even though imported sources from Malaysia account for 40% or so of overall supply as of 2009. Moreover, sustainability in this regard is so strategically important that all other matters of national concern ‘bend at the knee’, so to speak, in abeyance to this single outcome and issue. At present Singapore is dependent upon what are called its ‘four national taps’ as its supply strategy. In addition to importation, ‘local water catchment’ provides some supply, largely by way of collecting and channeling rainwater to Singapore’s 17 reservoirs via a network of rivers, canals and drains.

SummaryPurpose BAL101553, the prodrug of the microtubule-destabilizer BAL27862, previously showed signs of antitumor activity when administered as a 2-h infusion, but its use was limited by vascular toxicity. We investigated an alternative dosing strategy aimed at improving the safety profile of BAL101553. Methods This multicenter, open-label, Phase 1 dose-escalation study used a 3 + 3 design to determine the maximum tolerated dose (MTD), dose-limiting toxicities (DLTs), pharmacokinetics, and antitumor activity of BAL101553 administered as a 48-h IV infusion on Days 1, 8, and 15 of a 28-day cycle. Patients received oral BAL101553 on Days 15–21 of cycle 2 to assess oral bioavailability. Results BAL101553 was well tolerated at doses up to ≤70 mg/m2. Three grade 3 DLTs occurred: hypotension (70 mg/m2), hyponatremia and neutropenia (both 90 mg/m2). The MTD for 48-h IV BAL101553 was 70 mg/m2. At this dose level, the AUC for BAL27862 was 8580 ng.h/mL and the Cmax was 144 ng/mL. No apparent dose-related effects on blood pressure were observed with 48-h BAL101553 IV infusion. BAL27862 oral bioavailability was >80%. Conclusions Continuous 48-h IV BAL101553 infusion achieved higher exposure of the BAL27862 active metabolite than a 2-h infusion at the RP2D and did not cause vascular toxicity.

Abstract
Information transfer in generalized probabilistic theories (GPT) is an important problem. We have dealt with the problem based on repeatability postulate, which generalizes Zurek’s result to the GPT framework (Wu et al., Phys. Lett. A 379, 2694, 2015). A natural question arises: can we deduce the information transfer result under weaker assumptions? In this paper, we generalize Zurek’s result to the framework of GPT using weak repeatability postulate. We show that if distinguishable information can be transferred from a physical system to a series of apparatuses under the weak repeatability postulate in GPT, then the initial states of the physical system must be completely distinguishable. Moreover, after each step of invertible transformation, the composite states of the composite system composed of the physical systems and the apparatuses must also be completely distinguishable.

ABSTRACT:In Canada, recreational use of cannabis was legalized in October 2018. This policy change along with recent publications evaluating the efficacy of cannabis for the medical treatment of epilepsy and media awareness about its use have increased the public interest about this agent. The Canadian League Against Epilepsy Medical Therapeutics Committee, along with a multidisciplinary group of experts and Canadian Epilepsy Alliance representatives, has developed a position statement about the use of medical cannabis for epilepsy. This article addresses the current Canadian legal framework, recent publications about its efficacy and safety profile, and our understanding of the clinical issues that should be considered when contemplating cannabis use for medical purposes.

Abstract:Introduction:Hyperbaric oxygen therapy (HBOT) shows promising results in treating radionecrosis (RN) but there is limited evidence for its use in brain RN. The purpose of this study is to report the outcomes of using HBOT for symptomatic brain RN at a single institution.Methods:This was a retrospective review of patients with symptomatic brain RN between 2008 and 2018 and was treated with HBOT. Demographic data, steroid use, clinical response, radiologic response and toxicities were collected. The index time for analysis was the first day of HBOT. The primary endpoint was clinical improvement of a presenting symptom, including steroid dose reduction.Results:Thirteen patients who received HBOT for symptomatic RN were included. The median time from last brain radiation therapy to presenting symptoms of brain RN was 6 months. Twelve patients (92%) had clinical improvement with median time to symptom improvement of 33 days (range 1–109 days). One patient had transient improvement after HBOT but had recurrent symptomatic RN at 12 months. Of the eight patients with evaluable follow-up MRI, four patients had radiological improvement while four had stable necrosis appearance. Two patients had subsequent deterioration in MRI appearances, one each in the background of initial radiologic improvement and stability. Median survival was 15 months with median follow-up of 10 months. Seven patients reported side effects attributable to HBOT (54%), four of which were otologic in origin.Conclusions:HBOT is a safe and effective treatment for brain RN. HBOT showed clinical and radiologic improvement or stability in most patients. Prospective studies to further evaluate the effectiveness and side effects of HBOT are needed.

AbstractContinuing surgical antimicrobial prophylaxis after the incision is closed is not recommended in current guidelines. Our survey found that only 30.8% of hospitals had fully adopted these new recommendations. Feedback on prophylaxis duration was infrequently provided. Promoting guideline-concordant surgical antimicrobial prophylaxis discontinuation is an important target for future stewardship interventions.

Published: August 2019

AbstractThe quality of intimate relationships has been found to be a strong negative predictor for individuals’ mental and physical health problems. A significant predictor of relationship quality is adult attachment insecurity, but the mechanism by which attachment insecurity affects relationship quality needs further investigation. This study investigated whether self-compassion and compassion for one's partner mediated this association. Three hundred and forty-two individuals participated in an online survey assessing attachment anxiety and avoidance, compassionate and uncompassionate attitudes towards self and one's partner, as well as relationship quality and relationship satisfaction. The results showed that low self-compassionate attitude mediated the association between attachment anxiety and poor relationship quality. Further, low compassionate and high uncompassionate attitude towards one's partner mediated the association between attachment avoidance and poor relationship quality. No mediating effect was found for relationship satisfaction. Implications for interventions are discussed.

AbstractAcanthogyrus(Acanthosentis)maroccanus(Dollfus, 1951), an insufficiently described quadrigyrid acanthocephalan of cyprinid fishes from Northwest Africa, is redescribed based on recently collected specimens from the Algerian barbLuciobarbus callensis(Valenciennes) in Algeria. Newly observed morphological features forA.(A.)maroccanusinclude the arrangement of proboscis hooks (not in regular circles), the male reproductive structures extending into the copulatory bursa and the presence of a para-receptacle structure and vaginal sleeve. The mechanism of copulation of this acanthocephalan is described based on several copulating pairs. The phylogenetic position ofA.(A.)maroccanuswithin Eoacanthocephala was assessed based on partial 28S rDNA sequences. Maximum likelihood and Bayesian inference analyses placedA.(A.)maroccanusin a clade withPalliolisentis(Demidueterospinus)ophiocephalus(Thapar, 1931), both species included in the Quadrigyridae, the only family within the Gyracanthocephala.
America’s Largest Denomination: None
Authors: Norpoth Helmut 
Published: August 2019

ABSTRACTBy a measure of religious affiliation used by Gallup polls for nearly a century, the denomination with the largest following in the United States has always turned out to be “None,” ahead of Catholic, Methodist, Baptist, or any other faith. The existence of such a large flock without religious affiliation might be expected for a country with a Constitution guaranteeing freedom of and from religion. The secular portion of the American electorate has always been big enough to wield, potentially at least, political clout. Its partisan attachments have consistently favored the Democratic over the Republican side. What is limiting the electoral clout of the “Nones” today is that nearly half of them profess no partisan affiliation. They are Independents in matters of both churchandstate.
Exploring the Parameter Space of Point Spread Function Determination for the Scanning Electron Microscope—Part II: Effect on Image Restoration Quality
Authors: Nevins Mandy C. , Hailstone Richard K. , Lifshin Eric 
Published: August 2019

AbstractPoint spread function (PSF) deconvolution is an attractive software-based technique for resolution improvement in the scanning electron microscope (SEM) because it can restore information which has been blurred by challenging operating conditions. In Part 1, we studied a modern PSF determination method for SEM and explored how various parameters affected the method's ability to accurately estimate the PSF. In Part 2, we extend this exploration to PSF deconvolution for image restoration. The parameters include reference particle size, PSF smoothing (K), background correction, and restoration denoising (λ). Image quality was assessed by visual inspection and Fourier analysis. Overall, PSF deconvolution improved image quality. Low λ enhanced image sharpness at the cost of noise, while high λ created smoother restorations with less detail. λ should be chosen to balance feature preservation and denoising based on the application. Reference particle size within ±0.9 nm and K within a reasonable range had little effect on restoration quality. Restorations using background-corrected PSFs had superior quality compared with using no background correction, but if the correction was too high, the PSF was cut off causing blurrier restorations. Future efforts to automatically determine parameters would remove user guesswork, improve this method's consistency, and maximize interpretability of outputs.

AbstractGiant cell tumor (GCT) of bone is a common benign lesion that causes significant morbidity due to the failure of modern medical and surgical treatment. Surface ultra-structures of giant cells (GCs) may help in distinguishing aggressive tumors from indolent GC lesions. This study aimed to standardize scanning electron microscopic (SEM) imaging of GC from GCT of bone. Fresh GCT collected in Dulbecco's Modified Eagle Medium was washed to remove blood, homogenized, or treated with collagenase to isolate the GCs. Mechanically homogenized and collagenase-digested GCs were imaged on SEM after commonly used drying methodologies such as air-drying, tetramethylsilane (TMS)-drying, freeze-drying, and critical point-drying (CPD) for the optimization of sample processing. The collagenase-treated samples yielded a greater number of isolated GC and showed better surface morphology in comparison to mechanical homogenization. Air-drying was associated with marked cell shrinkage, and freeze-dried samples showed severe cell damage. TMS methodology partially preserved the cell contour and surface structures, although the cell shape was distorted. GC images with optimum surface morphology including membrane folding and microvesicular structures on the surface were observed only in collagenase-treated and critical point-dried samples. Collagenase digestion and critical point/TMS-drying should be performed for optimal SEM imaging of individual GCs.
