A negotiation‐based service selection approach using swarm intelligence and kernel density estimation
Authors: Mezni Haithem , Sellami Mokhtar 
Published: March 2018

SummaryNowadays, the cloud computing environment is becoming a natural choice to deploy and provide Web services that meet user needs. However, many services provide the same functionality and high quality of service (QoS) but different self‐adaptive behaviors. In this case, providers' adaptation policies are useful to select services with high QoS and high quality of adaptation (QoA). Existing approaches do not take into account providers' adaptation policies in order to select services with high reputation and high reaction to changes, which is important for the composition of self‐adaptive Web services. In order to actively participate to compositions, candidate services must negotiate their self‐* capabilities. Moreover, they must evaluate the participation constraints against their capabilities specified in terms of QoS and adaptation policies. This paper exploits a variant of particle swarm optimization and kernel density estimation in the selection of service compositions and the concurrent negotiations of their QoS and QoA capabilities. Selection and negotiation processes are held between intelligent agents, which adopt swarm intelligence techniques for achieving optimal selection and optimal agreement on providers' offers. To resolve unknown autonomic behavior of candidate services, we deal with the lack of such information by predicting the real QoA capabilities of a service through the kernel density estimation technique. Experiments show that our solution is efficient in comparison with several state‐of‐the‐art selection approaches.
What's Going On in a Graphic Novel?
Authors: Smith Jennifer M. , Pole Kathryn 
Published: March 2018

AbstractThe increase of graphic novels in libraries and schools and on award lists illustrates one way that children's literature is changing. This article explores the relation between words and illustrations in a popular graphic novel. The multimodal format of graphic novels requires readers to consider the words, graphics, panel sizes, and uses of color and line. Thus, the authors propose that (a) students need explicit instruction on how to read graphic novels, (b) graphic novel reading requires slow reading to attend to the details, and (c) opportunities to talk about text are necessary to explore the complexities of graphic novels.
The politics of adaptive climate management: Scientific recipes and lived reality
Authors: Warner Jeroen F. , Wesselink Anna J. , Geldof Govert D. 
Published: March 2018

While excited about the ground‐breaking work coming out of the epistemic community promoting adaptive (climate) management (AM), we worry about its tendency to ignore normative implications originating in the implicit worldviews underlying AM literature. Generally, AM has a “green” ideology and focuses on the bioregion as the only sensible level for analysis and action. This tendency for systemic functionalism of AM‐as‐(green)‐policy‐prescription depoliticizes an issue (“what to do about climate change”) that is political through and through. For example, those who stand to lose their livelihood as a result of AM plans or simply cannot adapt so fast may resist AM propositions. Implementing AM in practice thereby often leads to social and institutional engineering to overcome resistance. AM in academia seems quite far removed from the “real worlds” of social deliberation and praxis where policy is made and implemented, and where other values and interests than those implicit in AM prevail. We therefore highlight the importance of practices on the ground, claiming AM is not achieved by bioregional policies, but developed “on the hoof” at locally appropriate scales. Everyday professional work is characterized by “organized improvisation” where tacit professional and experiential knowledge are of prime importance.This article is categorized under:

Published: March 2018

AbstractIntroductionPrevious research on structural changes in early‐onset Alzheimer's disease (EOAD) and late‐onset Alzheimer's disease (LOAD) have reported inconsistent findings.MethodsIn the present substudy of the Gothenburg MCI study, 1.5 T scans were used to estimate lobar and hippocampal volumes using FreeSurfer. Study participants (N = 145) included 63 patients with AD, (24 patients with EOAD [aged ≤65 years], 39 patients with LOAD [aged >65 years]), 25 healthy controls aged ≤65 years, and 57 healthy controls aged >65 years.ResultsHippocampal atrophy is the most prominent feature of both EOAD and LOAD compared with controls. Direct comparison between EOAD and LOAD showed that the differences between the groups did not remain after correcting for age.DiscussionStructurally, EOAD and LOAD does not seem to be different nosological entities. The difference in brain volumes between the groups compared with controls is likely due to age‐related atrophy.

AbstractIntroductionThe objective of this study was to evaluate amyloid β (Aβ) deposition patterns in different groups of cerebral β amyloidosis: (1) nondemented with amyloid precursor protein overproduction (Down syndrome); (2) nondemented with abnormal processing of amyloid precursor protein (preclinical autosomal dominant Alzheimer disease); (3) presumed alteration in Aβ clearance with clinical symptoms (late‐onset AD); and (4) presumed alterations in Aβ clearance (preclinical AD).MethodsWe performed whole‐brain voxelwise comparison of cerebral Aβ between 23 Down syndrome, 10 preclinical autosomal dominant Alzheimer disease, 17 late‐onset AD, and 16 preclinical AD subjects, using Pittsburgh Compound B–positron emission tomography.ResultsWe found both Down syndrome and preclinical autosomal dominant Alzheimer disease shared a distinct pattern of increased bilateral striatal and thalamic Aβ deposition compared to late‐onset AD and preclinical AD.ConclusionDisorders associated with early‐life alterations in amyloid precursor protein production or processing are associated with a distinct pattern of early striatal fibrillary Aβ deposition before significant cognitive impairment. A better understanding of this unique pattern could identify important mechanisms of Aβ deposition and possibly important targets for early intervention.

ABSTRACTObjectiveThe purpose of this study was to assess the pattern of adult dog bites presenting to a medium size Canadian city’s Emergency Departments.MethodsAll adult (≥16 years) patients presenting to Emergency Departments in our region during a 30-month period (January 2013 to June 2015) were identified. Demographics, injury patterns, and dog-specific characteristics were studied.ResultsA total of 475 dog bites were identified. The greatest proportion of dog bites occurred in the summer months (140, 30%). Pit-bull type was the most frequently implicated breed (27%). The majority of patients identified were female (295, 62%). The majority of bites occurred in the hands (264 cases, 56%). Bites occurring in the head and neck accounted for 11% of all injuries. Although 50% of injuries required only washout and dressing, 15 cases (3%) required a complex primary closure. The operating room was utilized in the reconstruction of eight defects (2%). There were four (1%) tendon repairs, one (0.2%) nerve repair, and one injury requiring a skin graft (0.2%). Three patients were admitted to hospital. We identified an overall infection rate of 10%.ConclusionsDog bites most commonly occurred in the hands and upper extremities, and carried an infection risk of approximately 10%. Large, muscular breeds were the most frequently implicated. The effectiveness of breed-specific legislation remains unclear, but educational programs for dog owners, children, and health care workers may help decrease the number and severity of attacks.
Analyzing the Constitutional Theory of Money: Governance, Power, and Instability
Authors: MOUDUD JAMEE K. 
Published: March 2018

AbstractAt the heart of the constitutional theory of money is the argument that money is central to governance. This article explores the ways in which the core mechanism of the publicly undergirded monetary system, involving the incentivization and disciplining of private investors in the money creation process, creates its ‘fiscal value’ and generates both power struggles and possible instability in the unit of account. This twin dynamic of power and instability is intrinsic to alongue duréeanalysis of money. It is argued that since the current jural relations allocate money and power in particular ways, the basis is created for potential future political challenges to the status quoante, thereby creating instability. Further, the article emphasizes the centrality of the indeterminacy criterion which is at the core of the critical legal studies (CLS) framework, and its intimate connection to Keynes's notion of uncertainty. The indeterminacy/uncertainty nexus is used to explore how currency stability is determined or undermined by expectations, power struggles, tax contestations, and broader policy frameworks. Finally, the article relates this monetary theory to the literature on state-led industrialization and shows how such a constitutional money theory of industrialization is an alternative to the New Institutionalist perspective which emphasizes the centrality of ‘clear and well-defined’ property and contracts in order to create an ‘efficient’ economy.

Published: March 2018

AbstractTiming of seedling emergence is a critical aspect of a plant's life cycle, and it may influence the expression of other plant life history traits. However, most studies have been conducted at the population level, and thus little is known about timing of seedling emergence at the community level. In the field, we determined the peak emergence season for seedlings of 144 species collected from a subalpine meadow on the eastern Tibet Plateau in China. The proportion of species with seedlings emerging in autumn, spring and summer, seedling field emergence percentage (FE) and mean emergence time (MET) were analysed in relation to seed mass, life cycle type (annual/biennial and perennial) and phylogeny. The results showed that (1) the proportion of species with seedlings emerging in autumn (33%), spring (44%) and summer (23%) differed significantly; (2) overall, species with seedlings emerging in autumn had higher FE than those emerging during spring/summer; (3) there was a positive relationship between log-seed mass and log-MET, but log-seed mass had no significant effect on log-FE; (4) life cycle type did not affect seedling emergence; and (5) phylogeny significantly explained peak emergence season. These results suggest that seed mass and phylogenetic position are the main determinants of seedling emergence season. However, seedling peak emergence season affected FE, growing season length and resource utilization, and thus may be related to the importance of a species in the community.
Preoperative bioelectrical impedance predicts intensive care length of stay in children following cardiac surgery

Published: March 2018

AbstractWe have previously shown that children with a bioelectrical impedance spectroscopy phase angle at 50° (PA 50°) of <2.7 on postoperative day 2 had a four-fold increase in the risk of prolonged paediatric intensive care length of stay. In this study, we demonstrate a relationship between a baseline measure of phase angle 200/5° and postoperative length of stay.

Published: March 2018

AbstractObjectiveThe present research aimed to investigate the impact of the physical activity calorie equivalent (PACE) front-of-pack label on consumption, prospective consumption and liking of familiar and unfamiliar discretionary snack foods.DesignIn a within-subject randomised design, participants tasted and rated liking (9-point hedonic scale) and prospective consumption (9-point category scale) of four different snack foods with four different labels (i.e. blank, fake, PACE, PACE doubled) and four control snack foods. The twenty snack foods were presented during two 45 min sessions (i.e. ten snack foods per session) which were separated by one week. The amount participants sampled of each snack food was measured.SettingThe study was conducted in the Centre for Advanced Sensory Sciences laboratory at Deakin University, Australia.SubjectsThe participants were 153 university students (126 females, twenty-seven males, mean age 24·3 (sd 4·9) years) currently enrolled in an undergraduate nutrition degree at Deakin University.ResultsWhen the PACE label was present on familiar snack foods, participants sampled 9·9 % (22·8 (sem 1·4) v. 25·3 (sem 1·5) g, P=0·03) less than when such label was not present. This was in line with a decreased prospective snack food consumption of 9·1 % (3·0 (sem 0·2) v. 3·3 (sem 0·2) servings, P=0·03). Such pattern was not seen in unfamiliar snacks.ConclusionsThe PACE label appears to be a promising way to decrease familiar discretionary snack food consumption in young, health-minded participants.

AbstractIron deficiency chlorosis (IDC) is common among groundnut grown in calcareous and alkaline soils in India, China and Pakistan and causes considerable reduction in pod yield. To identify genetically diverse IDC tolerant accessions, the mini-core collection of groundnut representing geographical diversity was evaluated for IDC response over 2 years in iron-deficient calcareous soils. Enormous genetic variability was evident in the mini-core collection for IDC tolerance-related traits such as a visual chlorotic rating (VCR) and SPAD chlorophyll meter reading (SCMR) across five growth stages. Several IDC tolerant sources belonging to different botanical varieties such as hypogaea bunch (ICG # 5051, 6766, 5286, 6667, 4538, 14008, 5663, 9842, 11855), hypogaea runner (ICG 10479), fastigiata (ICG 10890) and vulgaris (ICG # 11651, 118) were identified. Among the six botanical varieties of groundnut, hypogaea bunch types were found most tolerant to IDC and this is the first report in groundnut. The IDC tolerant sources identified were irrespective of their country of origin. The principal component analysis based on VCR, SCMR, pod yield and its related traits revealed five major principal components that explained 80% of the total variation. The biplot generated using PC1 and PC2 revealed a distinct separation of IDC tolerant genotypes from the susceptible ones. The hierarchical clustering using five major principal components revealed seven major clusters that were mainly based on IDC response of the accessions.

Published: March 2018

AbstractThe facilitating role of the facial expression of surprise in the discrimination of the facial expression of fear was analyzed. The sample consisted of 202 subjects that undertook a forced-choice test in which they had to decide as quickly as possible whether the facial expression displayed on-screen was one of fear, anger or happiness. Variations were made to the prime expression (neutral expression, or one of surprise); the target expression (facial expression of fear, anger or happiness), and the prime duration (50 ms, 150 ms or 250 ms). The results revealed shorter reaction times in the response to the expression of fear when the prime expression was one of surprise, with a prime duration of 50 ms (p = .009) and 150 ms (p = .001), compared to when the prime expression was a neutral one. By contrast, the reaction times were longer in the discrimination of an expression of fear when the prime expression was one of surprise with a prime duration of 250 ms (p < .0001), compared to when the prime expression was a neutral one. This pattern of results was obtained solely in the discrimination of the expression of fear. The discussion focuses on these findings and the possible functional continuity between surprise and fear.
Comparative genomics sheds light on niche differentiation and the evolutionary history of comammox Nitrospira

Abstract
The description of comammox Nitrospira spp., performing complete ammonia-to-nitrate oxidation, and their co-occurrence with canonical β-proteobacterial ammonia oxidizing bacteria (β-AOB) in the environment, calls into question the metabolic potential of comammox Nitrospira and the evolutionary history of their ammonia oxidation pathway. We report four new comammox Nitrospira genomes, constituting two novel species, and the first comparative genomic analysis on comammox Nitrospira. Unlike canonical Nitrospira, comammox Nitrospira genomes lack genes for assimilatory nitrite reduction, suggesting that they have lost the potential to use external nitrite nitrogen sources. By contrast, compared to canonical Nitrospira, comammox Nitrospira harbor a higher diversity of urea transporters and copper homeostasis genes and lack cyanate hydratase genes. Additionally, the two comammox clades differ in their ammonium uptake systems. Contrary to β-AOB, comammox Nitrospira genomes have single copies of the two central ammonia oxidation pathway operons. Similar to ammonia oxidizing archaea and some oligotrophic AOB strains, they lack genes involved in nitric oxide reduction. Furthermore, comammox Nitrospira genomes encode genes that might allow efficient growth at low oxygen concentrations. Regarding the evolutionary history of comammox Nitrospira, our analyses indicate that several genes belonging to the ammonia oxidation pathway could have been laterally transferred from β-AOB to comammox Nitrospira. We postulate that the absence of comammox genes in other sublineage II Nitrospira genomes is the result of subsequent loss.
Vangl2 regulates spermatid planar cell polarity through microtubule (MT)-based cytoskeleton in the rat testis

Published: March 2018

AbstractDuring spermatogenesis, developing elongating/elongated spermatids are highly polarized cells, displaying unique apico-basal polarity. For instance, the heads of spermatids align perpendicular to the basement membrane with their tails pointing to the tubule lumen. Thus, the maximal number of spermatids are packed within the limited space of the seminiferous epithelium to support spermatogenesis. Herein, we reported findings that elongating/elongated spermatids displayed planar cell polarity (PCP) in adult rat testes in which the proximal end of polarized spermatid heads were aligned uniformly across the plane of the seminiferous epithelium based on studies using confocal microscopy and 3-dimensional (D) reconstruction of the seminiferous tubules. We also discovered that spermatid PCP was regulated by PCP protein Vangl2 (Van Gogh-like protein 2) since Vangl2 knockdown by RNAi was found to perturb spermatid PCP. More important, Vangl2 exerted its regulatory effects through changes in the organization of the microtubule (MT)-based cytoskeleton in the seminiferous epithelium. These changes were mediated via the downstream signaling proteins atypical protein kinase C ξ (PKCζ) and MT-associated protein (MAP)/microtubule affinity-regulating kinase 2 (MARK2). These findings thus provide new insights regarding the biology of spermatid PCP during spermiogenesis.

AbstractDespite considerable effort and significant therapeutic advances, age-related macular degeneration (AMD) remains the commonest cause of blindness in the developed world. Progressive late-stage AMD with outer retinal degeneration currently has no proven treatment. There has been significant interest in the possibility that cellular treatments may slow or reverse visual loss in AMD. A number of modes of action have been suggested, including cell replacement and rescue, as well as immune modulation to delay the neurodegenerative process. Their appeal in this enigmatic disease relate to their generic, non-pathway-specific effects. The outer retina in particular has been at the forefront of developments in cellular regenerative therapies being surgically accessible, easily observable, as well as having a relatively simple architecture. Both the retinal pigment epithelium (RPE) and photoreceptors have been considered for replacement therapies as both sheets and cell suspensions. Studies using autologous RPE, and to a lesser extent, foetal retina, have shown proof of principle. A wide variety of cell sources have been proposed with pluripotent stem cell-derived cells currently holding the centre stage. Recent early-phase trials using these cells for RPE replacement have met safety endpoints and hinted at possible efficacy. Animal studies have confirmed the promise that photoreceptor replacement, even in a completely degenerated outer retina may restore some vision. Many challenges, however, remain, not least of which include avoiding immune rejection, ensuring long-term cellular survival and maximising effect. This review provides an overview of progress made, ongoing studies and challenges ahead.
