Frame-invariant formulation of novel generalized Newtonian fluid constitutive equation for polymer melts

In this work, the frame-invariant formulation of a new generalized Newtonian fluid (GNF) constitutive equation is proposed. Viscosity is considered as a specific function of the second and third invariant of the strain rate tensor and of the second invariant of the objective velocity gradient. The GNF model was successfully tested using experimental data taken from the open literature for different high and low density polyethylene melts with varying amounts of long-chain branches utilizing steady-state shear, uniaxial, and planar extensional viscosities plotted as a function of the strain rate.
Corporate Risk Evaluation in the Context of Austrian Business Cycle Theory

This paper expands Fuller’s (2013) analysis of the net present value and interest rate changes in the context of the Austrian business cycle theory. During the boom phase of the business cycle, the economy shifts to a more risky position as the result of entrepreneurs’ profit targeting. To quantify this risk the duration, defined as the number of periods that elapse before the average present value dollar is received from a stream of cash flows, can be used. The new risk-adjusted net present value is created after applying the duration to capital asset pricing model determining the discount rate that should be used to calculate the present value of the project.
Gender-Based Violence and Alcohol Consumption in Youth Leisure Contexts: Challenges for Spanish Social Work

Adolescent leisure contexts in which alcohol are abused have undergone changes in recent decades, with the incorporation of girls/women to more intensive forms of consumption and with new forms of gender-based violence becoming more visible. This article studies the gender differences in the use and enjoyment of time in leisure contexts, the differences in the consumption of alcohol, and the vulnerabilities to which girls/women are subjected to in order to create proposals for Spanish social work intervention. We present empirical data from a qualitative study in which a sample of students from southern Spain have been interviewed in depth with the aim of establishing the connections between alcohol use and abuse and the instances of gender violence that occur in leisure contexts. Our final objective is to reflect upon and make innovative proposals for the role of Spanish professional social workers in prevention and intervention with young alcohol users and in the gender violence that is produced in the spaces of consumption.

Competition and gender: Time’s up on essentialist knowledge production

This article is an intervention in current trends of thinking about competition and gender in essentialist and stereotypical ways. Such thinking has produced numerous comparative studies measuring competitiveness of women and men; ‘proving’ men as competitive and women as non-competitive. Based on experiments and written questionnaires, these studies reduce gender to perceived biological sex and treat competition as a ‘self-evident’, static and easily measurable phenomenon. To contribute new understandings and learning, we surface five fallacies of this comparative research, explaining why the approach is misleading, inequitable and socially harmful. Drawing upon gender as a social construction and women leaders’ narratives, we offer a blueprint for democratising knowledge production. We write differently, choosing not to provide a ‘balanced’ view of the field and construct competition as a processual, complex and contextually specific phenomenon with underlying gender dynamics, rather than a discrete, observable and fixed in time event. The article provides learning: for leaders and managers to resist automatic categorisation on the basis of perceived biological sex; for management educators to challenge the ways that leadership and management are traditionally taught; and, for executive coaches to support changes in practice, by embracing complexity of the contemporary contexts in which leaders operate.
Control of Barents Sea Wintertime Cyclone Variability by Large‐Scale Atmospheric Flow

Extratropical cyclones transport heat and moisture into the Arctic, which can promote surface warming and sea ice melt. We investigate wintertime cyclone variability in the Barents Sea region to understand what controls the impacts, frequency, and path of cyclones at high latitudes. Large‐scale atmospheric conditions are found to be key, with the strongest surface warming from cyclones originating south of 60°N in the North Atlantic and steered northeastward by the upper‐level flow. Atmospheric conditions also control cyclone variability in the Barents proper: Months with many cyclones are characterized by an absence of high‐latitude blocking and enhanced local baroclinicity, due to the presence of strong upper‐level winds and a southwest‐northeast tilted jet stream more than changes in sea ice. This study confirms that Arctic cyclones exhibit large interannual variability, and accounting for this variability reveals that trends in Barents cyclone frequency are not robust over the 1979–2018 period.
Population genomics and history of speciation reveal fishery management gaps in two related redfish species (Sebastes mentella and Sebastes fasciatus)

Understanding the processes shaping population structure and reproductive isolation of marine organisms can improve their management and conservation. Using genomic markers combined with estimation of individual ancestries, assignment tests, spatial ecology, and demographic modeling, we (i) characterized the contemporary population structure, (ii) assessed the influence of space, fishing depth, and sampling years on contemporary distribution, and (iii) reconstructed the speciation history of two cryptic redfish species, Sebastes mentella and S. fasciatus. We genotyped 860 individuals in the Northwest Atlantic Ocean using 24,603 filtered single nucleotide polymorphisms (SNPs). Our results confirmed the clear genetic distinctiveness of the two species and identified three ecotypes within S. mentella and five populations in S. fasciatus. Multivariate analyses highlighted the influence of spatial distribution and depth on the overall genomic variation, while demographic modeling revealed that secondary contact models best explained inter‐ and intragenomic divergence. These species, ecotypes, and populations can be considered as a rare and wide continuum of genomic divergence in the marine environment. This acquired knowledge pertaining to the evolutionary processes driving population divergence and reproductive isolation will help optimizing the assessment of demographic units and possibly to refine fishery management units.
Parametric optimization and ranking analysis of hybrid epoxy polymer composites based on mechanical, thermo-mechanical and abrasive wear performance

In this research work, designing and fabrication of hybrid epoxy polymer composite materials had been carried out. It consists of basalt fiber (constant fraction) and marble dust particulates (0–10 wt% @ step of 2.5%) ensuing five compositions namely, MBE-0, MBE-2.5, MBE-5, MBE-7.5, and MBE-10. The specimen’s undergone physical, mechanical, and thermo-mechanical characterizations followed by three-body abrasive wear performance evaluation. Parametric optimizations of the wear have been evaluated with the Taguchi technique. The performance data are used to rank the compositions using a hybrid AHP-VIKOR selection making tool. It has been observed that voids content improves with reinforcement up to 5 wt% marble dust reinforcement, thereafter, it deteriorates sharply. The mechanical properties with 5 wt% marble dust reinforcement found to be highest. The thermo-mechanical characteristics like modulus and damping improve with marble dust reinforcement and temperature. The Cole-Cole plots reveal the heterogeneity present in the composites. The Taguchi’s analysis reveals the order of operating factors influencing specific wear rate as abrading distance > normal load > reinforcement composition > abrasive size. The steady state-specific wear rate of the composites reveals decremented rate across the abrading distance range irrespective of reinforcement proportions and at any specific abrading distance the order it followed as MBE-5 < MBE-7.5 < MBE-2.5 < MBE-10 < MBE-0. The ranking analysis using hybrid AHP-VIKOR technique predicts the ranking sequence as MBE-5 > MBE-7.5 > MBE-2.5 > MBE-10 > MBE-0, which are in-line with subjective analysis.
An accurate and efficient two‐phase scheme for detecting Android cloned applications

The fast‐growing Android application market has attracted more and more application developers. However, many plagiarists use decompiled tools to modify original applications to get clones, which has become a serious threat. For detecting cloned applications, most of the existing schemes do not consider the detected accuracy and time consumption at the same time. In this article, we propose a two‐phase detection scheme to achieve fast and accurate clone detection in large‐scale applications. In the rapid screening phase, a fix‐length minhash summary is constructed for each application and the locality‐sensitive hashing (LSH) algorithm is used to obtain suspicious cloned applications quickly. In the accurate detection phase, by merging and pruning the layout and interaction information of all user interfaces (UIs) at the application runtime, we obtain the birthmark named merged layout tree (MLT), which can resist nested obfuscation and repacking attack. Finally, cloned apps are detected by calculating the similarity between MLTs from suspicious cloned apps. We evaluate our detection scheme in two app datasets (nearly 170,000 Android applications) and compare it with the state‐of‐the‐art clone detection methods. Extensive experiments show that our method has high accuracy and efficiency for clone detection in large‐scale apps.
Description of a New Species of Killifish of the Genus Profundulus (Atherinomorpha: Profundulidae) from the Mexican State of Oaxaca

The Middle American killifish genus Profundulus occurs in most Pacific and Atlantic drainages from the Mexican state of Guerrero to the Chamelecón River in Honduras, with highest species diversity in southern Mexico. In this study, we describe a new member of the genus, Profundulus parentiae, new species, from the Mexican state of Oaxaca. It is distinguished from P. guatemalensis and P. kreiseri by having rows of dots on the sides of the body. Profundulus parentiae, new species, can be distinguished from P. oaxacae by having 33 lateral scales, versus 29–31 in P. oaxacae. Profundulus parentiae, new species, can be distinguished from P. balsanus, P. oaxacae, and P. mixtlanensis by the presence of long epiotic processes that extend beyond the epipleural ribs of the first vertebra, versus short epiotic processes not reaching the epipleural ribs of the first vertebra. Profundulus parentiae, new species, can be differentiated from P. punctatus by the presence of a dorso-ventrally compressed Meckel's cartilage with a relatively straight medial process and a narrow and strongly concave sesamoid articular, versus a dorso-ventrally expanded Meckel's cartilage with concave medial process and a wide and moderately concave sesamoid articular. Based on the phylogenetic analysis of molecular sequence data, the new species is recovered as the sister taxon to P. balsanus. The discovery and description of this new species in southeastern Mexico, raises the number of species from this region to five and suggests that this area has been an important center for diversification within this lineage of killifishes.
Restoration of macroinvertebrates, fish, and habitats in streams following mining subsidence: replicated analysis across 18 mitigation sites

Human activities have led to declines in stream functioning and stream restoration seeks to reverse this trend. Longwall coal mining, an underground full‐extraction method, can cause surface subsidence, affecting streams by creating a series of deep pools that trap sediment, reduce habitat diversity, and impair macroinvertebrate and fish communities. Mining effects on streams must be mitigated to maintain the functions, values, and foreseeable uses of streams. Gate cutting is a procedure that alleviates pooling by reestablishing the stream grade, accompanied by procedures that stabilize the channel, restore substrates, and enhance in‐stream and riparian habitats. We evaluated effectiveness of gate cuts at restoring streams affected by subsidence pooling at 18 independent restoration sites over two mines in southwestern Pennsylvania, U.S.A. At each site, sampling stations were established to monitor effects of mining subsidence and its restoration on macroinvertebrates, fish communities, and habitats. We tested for effects of sequential interventions (subsidence and restoration) on biological and habitat variables in a replicated before–after design, controlling for potentially confounding temporal effects (sample month and antecedent effective precipitation). All biological indices and substrate‐related habitat indices declined following subsidence but improved following restoration. Macroinvertebrate indicex and taxa richness, substrates, and riparian vegetation continued to improve with time following restoration. Whereas other studies have concluded that biological communities may take many years to respond to restoration, these results indicate that where macroinvertebrate and fish communities are altered by subsidence pooling, they can be effectively restored using gate cuts to pre‐mining levels within relatively short time periods.
Optimising trait and source selection for explaining occurrence and abundance changes: A case study using British butterflies

1.Functional traits that define the ecological role of an organism are increasingly being used to determine and predict responses to environmental change. Functional trait analyses of butterflies remain underexplored compared with other taxa, such as plants. Previous works using butterfly functional traits have not comprehensively addressed issues about the quality of trait datasets used and the relative predictive power of different trait types. 2.We compare the consistency of trait descriptions between six widely used trait sources for the British butterfly fauna. We analysed consistency of trait sources using Fleiss's kappa and intraclass correlation coefficient. Principal component analysis was used to produce species ordinations, comparing outputs to examine which trait sets were better at explaining recent species range and abundance changes within the UK. 3.There was a large range in congruence values for specific traits between sources. No single source can be relied upon to produce accurate trait information for British butterflies. Most trait sets are poor predictors of abundance and occurrence changes but are better at predicting current occurrence. An extensive trait set, supplementing biotope‐related traits with explicit resource‐based information recovers more informative ecological classifications and models than those primarily based on life‐history traits or biotope descriptors. Smaller trait sets do, however, recover the specialist–generalist continuum. 4.We conclude that analyses of distribution and abundance changes that rely on traits are highly dependent on trait source and trait type. For butterflies, traits that are based on measures of biotope occupancy should be avoided in explaining changes of abundance and distribution. Including trait information that describes their resource requirements is essential for such analyses.
GENERATION OF ARABIDOPSIS LINES WITH ALTERED CYTOKININ LEVEL EXPRESSING GFP-FUSED CYTOSKELETAL PROTEINS

Cell division, expansion and differentiation require a sophisticated spatial arrangement of the cytoskeleton. The ever increasing progress in fluorescent microscope techniques has allowed to visualize rearrangements and dynamics of actin and microtubule arrays in various cell types and tissues in plants. Processes controlling proper cytoskeleton organisation and its response to various stimuli, mediated by actin and microtubule binding proteins as well as plant hormones, are being an area of active investigation. As the current research of cytoskeleton regulation focused mainly on hormone auxin, the involvement of cytokinin is still unclear. In this study, we describe generation of transgenic lines of Arabidopsis thaliana comprising inducible system for manipulation of endogenous cytokinin level and simultaneously GFP-labelled actin or microtubule proteins. These lines serve as a tool for the study of cytokinin mode of action in the course of cell/organ development. Based on our results, it is obvious that cytokinins play a considerable role in modulation of plant cytoskeleton. However, further research is necessary to elucidate precise cytokinin signalling pathways and cross-talk with other hormones, which participate in such complex processes of cell morphology.
Assessment of cotton fibre length measurement methods

Abstract This study was conducted to explore new opportunities to deliver accurate and reliable measurements in terms of fibre length distribution. Ten samples of cotton fibre with a wide range of mean length ranging from 24.28 to 32.38 mm and a short fibre content (SFC%) ranging from 7.3% to 17.4% were selected. In Part 1 of the study, the fibre was tested using the more traditional methods, which include HVI, AFIS and SWA. There were strong positive and significant relationships between the various fibre length measurements provided by the three methods. Although there were moderate relationships between SFC% as measured by HVI and AFIS, the relationship with SWA was low and negative. In Part 2 of the study, cotton sliver, from the above-mentioned fibre was tested on AFIS, Almeter , Fibrotest and OFDA 4000. There were also moderate and strong positive relationships between all the length measurements, including SFC% as measured by AFIS, Almeter, Fibrotest and OFDA 4000.
Reducing the number of experiments required for modelling the hydrocracking process with kriging through Bayesian transfer learning

The objective is to improve the learning of a regression model of the hydrocracking process using a reduced number of observations. When a new catalyst is used for the hydrocracking process, a new model must be fitted. Generating new data is expensive and therefore it is advantageous to limit the amount of new data generation. Our idea is to use a second data set of measurements made on a process using an old catalyst. This second data set is large enough to fit performing models for the old catalyst. In this work, we use the knowledge from this old catalyst to learn a model on the new catalyst. This task is a transfer learning task. We show that the results are greatly improved with a Bayesian approach to transfer linear model and kriging model.
Investigating the abundance and flight period of bark beetles (Coleoptera: Curculionidae: Scolytinae) over elevational gradients in Sitka spruce forests

A warming climate, as predicted under current climate change projections, is likely to influence the population dynamics of many forest insect species. Numerous bark beetle species in both Europe and North America have already responded to a warming climate by significantly expanding their geographical ranges. The aim of the current study was to investigate how populations of bark beetles within stands of Sitka spruce, a widely planted non‐native commercial plantation tree species in the U.K., were likely to respond to a warming climate. Experimental plots were established in stands of Sitka spruce over elevational gradients in two commercial forest plantations, and the abundance and emergence times of key bark beetle species were assessed over a 3‐year period using flight interception traps. The air temperature difference between the lowest and highest experimental plot in each forest was consistently >1°C throughout the 3‐year period. In general, the abundance of the most dominant bark beetle species (e.g. Trypodendron, Dryocoetes, Hylastes spp.) was higher, and emergence times tended to be earlier in the year at the lower elevation plots, where temperatures were higher, although not all bark beetle species responded in the same manner. The results of the study indicated that, under the projected future climate warming scenarios, monoculture Sitka spruce stands at low elevations may potentially be more vulnerable to significant outbreak events from existing or invasive bark beetle species. Hence, consideration of establishing more resilient forests of Sitka spruce by diversifying the species composition and structure of Sitka spruce stands is discussed.
