Published: February 2023

AbstractThe software is changing rapidly with the invention of advanced technologies and methodologies. The ability to rapidly and successfully upgrade software in response to changing business requirements is more vital than ever. For the long‐term management of software products, measuring software maintainability is crucial. The use of soft computing techniques for software maintainability prediction has shown immense promise in software maintenance process by providing accurate prediction of software maintainability. To better understand the role of soft computing techniques for software maintainability prediction, we aim to provide a systematic literature review of soft computing techniques for predicting software maintainability. Firstly, we provide a detailed overview of software maintainability. Following this, we explore the fundamentals of software maintainability and the reasons for adopting soft computing methodologies for predicting software maintainability. Later, we examine the soft computing approaches employed in the process of software maintainability prediction. Furthermore, we discuss the difficulties and potential solutions associated with the use of soft computing techniques in predicting maintainability of software. Finally, we conclude the review with some promising future directions to drive further research innovations and developments in this promising area. This systematic literature review provides a comprehensive overview of the soft computing strategies utilized for software maintainability for future researchers.
The consequences of density‐dependent individual growth for sustainable harvesting and management of fish stocks
Authors: Croll Jasper C. , van Kooten Tobias , de Roos André M. 
Published: February 2023

AbstractDensity dependence is likely to act as a regulatory mechanism in fish stocks that are recovering from overfishing. In general, density dependence in fish stocks is assumed to only occur in reproduction and early life stages and is therefore usually modelled as a stock‐recruitment relationship. Recent research shows that density dependence can also reduce individual growth in body size later in life. In this study, we show how optimal fishing effort changes with the strength of density dependence in individual growth for four stocks of North Sea flatfish species. Using size‐structured population models we show that density dependence arises due to a mechanistic link between the resource availability and life history processes at the individual level. We furthermore show that the stock response to harvesting is either driven by changes in individual reproduction when density dependence in individual growth is weak or by changes in individual growth rate when individual growth is strongly affected by density dependence. These two types or regimes are separated by a sudden shift in dynamics. It is therefore of great importance to account for density dependence in growth when managing fish stocks.

Published: February 2023

AbstractObjectivesWe included two sacrifice constructs to reflect the awareness and (in)equity of behavioral sacrifice in same‐sex relationships: (a) the receiver's awareness (whether the receiver under‐, over‐, or unbiasedly estimated the other's frequency of sacrifice behaviors) and (b) the provider's perceived (in)equity (whether the provider perceived themselves as underbenefitted, overbenefitted, or equitably treated). We then tested how heterosexist discrimination related to same‐sex couples' relationship quality via receivers' awareness and providers' perceived (in)equity.BackgroundSacrifices are pro‐relationship efforts in which individuals forgo self‐interests for the partner or the relationship. The links from sacrifice to same‐sex couples' relationship quality are still understudied. Further, no study has examined whether sexual minority stressors relate to sacrifice in same‐sex relationships.MethodWe used dyadic, survey data from 141 same‐sex couples and conducted actor–partner interdependence models.ResultsFor receivers' awareness, unbiased estimation and overestimation were related to higher relationship quality; underestimation was related to lower relationship quality. For providers' perceived (in)equity, being underbenefitted—a situation in which individuals perceived that the other made fewer sacrifices than they did—was related to lower relationship quality. For indirect pathways, when one individual encountered heterosexist discrimination, this individual's sacrifice was likely underestimated by the receiver; in turn, this individual's partner experienced low relationship quality.ConclusionsTo better understand sacrifice and relationship quality for same‐sex couples, heterosexist discrimination should be considered.ImplicationsInterventions are needed when practitioners work with same‐sex couples who feel that their sacrifices were underestimated, and efforts are still needed to reduce heterosexist discrimination.

Published: February 2023

AbstractObjectiveThis study examined sex and sexual orientation differences in the context of the effects of coping strategies on relationship satisfaction.BackgroundThe sex and sexual orientation differences on the association between coping strategies and relationship satisfaction are not yet fully understood.MethodThe participants were 3,805 Belgian individuals who self‐identified as heterosexual (n = 2,024), bisexual (n = 790), or gay/lesbian (n = 991).ResultsResults showed that (a) task‐oriented and emotion‐oriented coping was positively and negatively associated with relationship satisfaction, respectively; (b) social diversion–oriented coping was positively associated with relationship satisfaction only among those who identified as heterosexual, gay, or lesbian; and (c) distraction‐oriented coping was positively associated with relationship satisfaction only among those identifying as bisexual. Multiple group tests based on sex within each sexual orientation category confirm that (a) a stronger association was observed between task‐oriented coping and relationship satisfaction for bisexual men compared to bisexual women; (b) the negative association between emotion‐oriented coping and relationship satisfaction is only significant for heterosexual women, and not for bisexual women; and (c) the negative association between distraction‐oriented coping and relationship satisfaction is significant for bisexual women, but not for heterosexual women.ConclusionThis study enhances our comprehension of the variations in the utilization of coping strategies and their effect on relationship satisfaction among individuals based on their sex and sexual orientation.ImplicationsThese findings might lead to improved interventions related to coping strategies for reducing the effect of stress in romantic relationships.

Authors: Patrício Lurdes D. , Ferreira João J. 
Published: February 2023

AbstractAs key players in innovation and entrepreneurial ecosystems, Higher Education Institutions (HEI) assume a position as catalysts in creating and disseminating knowledge with repercussions in the societal, economic, political and innovation environments. In this scenario, HEI are facing the need to balance the performance of their traditional missions—teaching and research—with the pursuit of entrepreneurial performance. This brings awareness of the need to pay particular attention to HEI entrepreneurial performance (HEIEP) and how to measure it. Based on HEInnovate, a self‐assessment tool resulting from a joint effort of the European Community and the OECD, this study aims to explore the benefits of university entrepreneurial metrics, analysing HEIEP as a discriminant function of the HEInnovate dimensions complemented with a qualitative approach using Fuzzy Set Qualitative Comparative Analysis (fsQCA). The analysis provides valuable details, presenting recipes based on the HEInnovate dimensions or combinations of dimensions to achieve a mission legitimation. This research brings awareness to the use of the HEInnovate scale, where it is possible to highlight the importance of the digital transformation and capability dimension to entrepreneurial performance (EP) and university mission legitimation.

AbstractBoth high pyroelectric coefficient and figure of merits of ferroelectric materials are desirable for infrared detection. In this work, we prepared Pb0.99Nb0.02[(Zr0.57Sn0.43)1−xTix]0.98O3 (0.060 ≤ x ≤ 0.080) ceramics, and the microstructure and electric properties were studied systematically. It is observed that the composition x = 0.07 shows enhanced pyroelectric properties around ambient temperature due to the ferroelectric–antiferroelectric phase transition, with the pyroelectric coefficient p = 6.83 × 10−4 C m−2 K−1 and the figures of merit Fi = 5.04 × 10−10 m V−1, Fv = 7.61 × 10−2 m2 C−1, and Fd = 3.46 × 10−5 Pa−1/2 at room temperature and the highest pyroelectric coefficient of 695.5 × 10−4 C m−2 K−1 and Fi = 1410.46 × 10−10 m V−1, Fv = 1587.39 × 10−2 m2 C−1, and Fd = 1182.94 × 10−5 Pa−1/2 at 36.7°C. These values are superior to other pyroelectric materials. These results indicate that this system is a promising pyroelectric material for the applications of infrared detectors.

AbstractBackgroundDysphagia can have serious health implications including choking and respiratory infection leading to poorer quality of life. People with intellectual disabilities are at higher risk of dysphagia related health complications and early death. Robust dysphagia screening tools are vital for this population.MethodA scoping review and appraisal of the evidence for dysphagia and feeding screening tools for use with people with intellectual disabilities was undertaken.ResultsSeven studies (using six screening tools) met the review inclusion criteria. Mostly studies were limited by no defined dysphagia criteria, no verification of tools with a gold reference standard (e.g., videofluoroscopic examination) and lack of participant diversity (small samples, narrow age range, severity of intellectual disability or limited settings).ConclusionsThere is urgent need for development and rigorous appraisal of existing dysphagia screening tools to meet the needs of a wider range of people with intellectual disabilities (particularly mild‐to‐moderate severity) and in wider settings.
“Pill‐in‐Pocket” anticoagulation for stroke prevention in atrial fibrillation
Authors: Peigh Graham , Passman Rod S. 
Published: February 2023

AbstractUninterrupted anticoagulation for atrial fibrillation (AF), regardless of AF burden, is deeply rooted in practice since the early anticoagulation trials. However, uninterrupted anticoagulation is not without risks, and may not be beneficial for allcomers with a history of AF. Indeed, contemporary data that support a critical duration threshold of AF that benefits from anticoagulation, and a temporal association between stroke and multihour AF episodes, compel the study of a more targeted approach to AF anticoagulation. In this review, we discuss data that support further investigation of “pill in the pocket” anticoagulation for AF, and introduce the pivotal Rhythm Evaluation for Anticoagulation Therapy for Atrial Fibrillation (REACT‐AF) trial that will robustly evaluate this strategy.

AbstractIntroductionPreliminary data suggest that high power short duration (HPSD) ablation for pulmonary vein isolation (PVI) are safe. Limited data are available on its effectiveness. Aim was to evaluate HPSD ablation in atrial fibrillation ablation using a novel Qdot Micro catheter.Methods and ResultsProspective multicenter study evaluating safety and efficacy of PVI with HPSD ablation. First pass isolation (FPI) and sustained PVI was assessed. If FPI was not achieved additional ablation index (AI)‐guided ablation with 45 W was performed and metrics predictive of this were determined. Sixty‐five patients and 260 veins were treated. Procedural and LA dwell time was 93.9 ± 30.4 and 60.5 ± 23.1 min, respectively. FPI was achieved in 47 (72.3%) patients and 231 veins (88.8%) with an ablation duration of 4.6 ± 1.0 min. Twenty‐nine veins required additional AI‐guided ablation to achieve initial PVI with 24 anatomical sites ablated with the right posterior carina being the most common site (37.5%). A contact force of ≥8 g (area under the curve [AUC]: 0.81; p < 0.001) and catheter position variation of ≤1.2 mm (AUC: 0.79; p < 0.001) with HPSD were strongly predictive of not requiring additional AI‐guided ablation. Out of the 260 veins, only 5 (1.9%) veins showed acute reconnection. HPSD ablation was associated with shorter procedure times (93.9 vs. 159.4 min; p < 0.001), ablation times (6.1 vs. 27.7 min; p < 0.001), and lower rates of PV reconnection (9.2% vs. 30.8%; p = 0.004) compared to moderate power cohort.ConclusionsHPSD ablation is an effective ablation modality which results in effective PVI whilst maintaining a safety profile. Its superiority needs to be evaluated in randomized controlled trials.

AbstractBackgroundThe diagnostic work‐up for cardiac arrest from ventricular tachyarrhythmias occurring in younger adults and structurally normal hearts is variable and often incomplete.MethodsWe reviewed records for all recipients of a secondary prevention implantable cardiac defibrillator (ICD) younger than 60 years at a single quaternary referral hospital from 2010 to 2021. Patients with unexplained ventricular arrhythmias (UVA) were identified as those with no structural heart disease on echocardiogram, no obstructive coronary disease, and no clear diagnostic features on ECG. We specifically evaluated the adoption rate of five modalities of “second‐line” cardiac investigations: cardiac magnetic resonance imaging (CMR), exercise ECG, flecainide challenge, electrophysiology study (EPS), and genetic testing. We also evaluated patterns of antiarrhythmic drug therapy and device‐detected arrhythmias and compared them with secondary prevention ICD recipients with a clear etiology found on initial assessment.ResultsOne hundred and two recipients of a secondary prevention ICD under the age of 60 were analyzed. Thirty‐nine patients (38.2%) were identified with UVA and were compared with the remaining 63 patients with VA of clear etiology (61.8%). UVA patients were younger (35.6 ± 13.0 vs. 46.0 ± 8.6 years, p < .001) and were more often female (48.7% vs. 28.6%, p = .04). CMR was performed in 32 patients with UVA (82.1%), whereas flecainide challenge, stress ECG, genetic testing, and EPS were only performed in a minority of patients. Overall, the use of a second‐line investigation suggested an etiology in 17 patients with UVA (43.5%). Compared to patients with VA of clear etiology, UVA patients had lower rates of antiarrhythmic drug prescription (64.1% vs. 88.9%, p = .003) and had a higher rate of device‐delivered tachy‐therapies (30.8% vs. 14.3%, p = .045).ConclusionIn this real‐world analysis of patients with UVA, the diagnostic work‐up is often incomplete. While CMR was increasingly utilized at our institution, investigations for channelopathies and genetic causes appear to be underutilized. Implementation of a systematic protocol for work‐up of these patients requires further study.
Evolutionary coexistence in a fluctuating environment by specialization on resource level
Authors: Wortel Meike T. 
Published: February 2023

AbstractMicrobial communities in fluctuating environments, such as oceans or the human gut, contain a wealth of diversity. This diversity contributes to the stability of communities and the functions they have in their hosts and ecosystems. To improve stability and increase production of beneficial compounds, we need to understand the underlying mechanisms causing this diversity. When nutrient levels fluctuate over time, one possibly relevant mechanism is coexistence between specialists on low and specialists on high nutrient levels. The relevance of this process is supported by the observations of coexistence in the laboratory, and by simple models, which show that negative frequency dependence of two such specialists can stabilize coexistence. However, as microbial populations are often large and fast growing, they evolve rapidly. Our aim is to determine what happens when species can evolve; whether evolutionary branching can create diversity or whether evolution will destabilize coexistence. We derive an analytical expression of the invasion fitness in fluctuating environments and use adaptive dynamics techniques to find that evolutionarily stable coexistence requires a special type of trade‐off between growth at low and high nutrients. We do not find support for the necessary evolutionary trade‐off in data available for the bacterium Escherichia coli and the yeast Saccharomyces cerevisiae on glucose. However, this type of data is scarce and might exist for other species or in different conditions. Moreover, we do find evidence for evolutionarily stable coexistence of the two species together. Since we find this coexistence in the scarce data that are available, we predict that specialization on resource level is a relevant mechanism for species diversity in microbial communities in fluctuating environments in natural settings.
Towards real‐time STEM simulations through targeted subsampling strategies

Published: February 2023

AbstractScanning transmission electron microscopy images can be complex to interpret on the atomic scale as the contrast is sensitive to multiple factors such as sample thickness, composition, defects and aberrations. Simulations are commonly used to validate or interpret real experimental images, but they come at a cost of either long computation times or specialist hardware such as graphics processing units. Recent works in compressive sensing for experimental STEM images have shown that it is possible to significantly reduce the amount of acquired signal and still recover the full image without significant loss of image quality, and therefore it is proposed here that similar methods can be applied to STEM simulations. In this paper, we demonstrate a method that can significantly increase the efficiency of STEM simulations through a targeted sampling strategy, along with a new approach to independently subsample each frozen phonon layer. We show the effectiveness of this method by simulating a SrTiO3 grain boundary and monolayer 2H‐MoS2 containing a sulphur vacancy using the abTEM software. We also show how this method is not limited to only traditional multislice methods, but also increases the speed of the PRISM simulation method. Furthermore, we discuss the possibility for STEM simulations to seed the acquisition of real data, to potentially lead the way to self‐driving (correcting) STEM.

AbstractUnderstanding the factors that govern variation in genetic structure across species is key to the study of speciation and population genetics. Genetic structure has been linked to several aspects of life history, such as foraging strategy, habitat association, migration distance, and dispersal ability, all of which might influence dispersal and gene flow. Comparative studies of population genetic data from species with differing life histories provide opportunities to tease apart the role of dispersal in shaping gene flow and population genetic structure. Here, we examine population genetic data from sets of bird species specialized on a series of Amazonian habitat types hypothesized to filter for species with dramatically different dispersal abilities: stable upland forest, dynamic floodplain forest, and highly dynamic riverine islands. Using genome‐wide markers, we show that habitat type has a significant effect on population genetic structure, with species in upland forest, floodplain forest, and riverine islands exhibiting progressively lower levels of structure. Although morphological traits used as proxies for individual‐level dispersal ability did not explain this pattern, population genetic measures of gene flow are elevated in species from more dynamic riverine habitats. Our results suggest that the habitat in which a species occurs drives the degree of population genetic structuring via its impact on long‐term fluctuations in levels of gene flow, with species in highly dynamic habitats having particularly elevated gene flow. These differences in genetic variation across taxa specialized in distinct habitats may lead to disparate responses to environmental change or habitat‐specific diversification dynamics over evolutionary time scales.
