Duplication‐controlled static energy‐efficient scheduling on multiprocessor computing system
Authors: Kaur Nirmal , Bansal Savina , Bansal Rakesh Kumar 
Published: March 2017

SummaryEnergy‐efficient scheduling is a step towards meeting green computing requirements. The work in this direction mainly aims at reducing dynamic energy consumption that includes clock gating, cache subbanking, and dynamic voltage and frequency scaling of underlying processors. However, the emergence of fast and compact transistor sizes has exponentially added onto the processor static power consumption, which has not been paid much attention. This article proposes a duplication‐controlled static energy‐efficient scheduling (C‐SEED) algorithm for scheduling precedence constrained applications on parallel computing systems. The C‐SEED algorithm couples adaptive threshold‐based duplication with system level dynamic power management technique to achieve its objectives. Dynamic power management works by selectively putting the energy‐consuming resources to efficient low‐power states for idle times to reduce energy consumption. Efficacy of the proposed algorithm is analyzed and compared against other relevant works on the basis of makespan and total energy (dynamic + static + communication) consumption. The extensive simulation results carried over large set of random and regular task graphs show that the proposed C‐SEED algorithm has potential to reduce energy consumption as well as makespan.

Childhood maltreatment (CM) has been indicated as a predictor of a differential response to antidepressant treatment with psychotherapy compared to medication. In this secondary analysis, we investigated whether the presence of CM results in a differential indication for the Cognitive Behavioral Analysis System of Psychotherapy (CBASP) or escitalopram plus clinical management (ESC). Sixty patients with chronic depression were randomized to either 22 sessions of CBASP or ESC over the course of 8 weeks of acute and 20 weeks of extended treatment at 2 German treatment sites. CM was assessed using the Childhood Trauma Questionnaire and the clinician rated Early Trauma Inventory. Intention‐to‐treat analyses were used to examine the impact of CM on depression, global functioning, and quality of life. The presence of CM did not result in significant differences in treatment response to CBASP or ESC on any outcome measure after 28 weeks of treatment independent of the type of CM assessment. After 8 weeks, a significant CM × treatment interaction was found for scores on the Montgomery‐Asberg Depression Rating Scale. Patients with a history of CM receiving CBASP had a significantly lower response rate compared to patients without CM and to those receiving ESC after 8 weeks. Conclusively, CBASP and ESC are equally effective treatment options for the difficult to treat subgroup of patients with chronic depression and a history of CM. CM may be a predictor of a longer latency of treatment response in the case of psychotherapy.Key Practitioner Message

AbstractBoron dipyrromethene (BODIPY) and its derivatives are known to be efficient photon‐harvesting chromophores. However, their study as active materials in bulk heterojunction (BHJ) solar cells is still scarce. In this study, the development of new synthetic ways to design original BODIPY‐based dumbbell‐shape molecules, including a first 2,3,5,6‐tetravinyl aromatic BODIPY molecule, is reported. High fill factors can be obtained in BHJ solar cells when blended with a fullerene derivative, leading to a new record BODIPY‐based power conversion efficiency of 5.8 %.

SummaryThe researchers are using the various variations of re‐encryption schemes, which migrate the computational intensive re‐encryption jobs of mobile devices to the trusted entity/cloud. However, the messages are still encrypted and decrypted using the limited computational power of mobile devices.Our contribution in this paper is to propose a workload distribution model for re‐encryption schemes, which offloads the computational intensive operations, such as encryption and decryption on a trusted entity. Moreover, the proposed workload distribution model is compared with existing re‐encryption schemes of resource utilization on trusted entity and mobile device. The experimental results show substantial improvement in performance compared to the existing schemes.
Competition and facilitation structure plant communities under nurse tree canopies in extremely stressful environments
Authors: Al‐Namazi Ali A. , El‐Bana Magdy I. , Bonser Stephen P. 
Published: March 2017

AbstractNurse plant facilitation in stressful environments can produce an environment with relatively low stress under its canopy. These nurse plants may produce the conditions promoting intense competition between coexisting species under the canopy, and canopies may establish stress gradients, where stress increases toward the edge of the canopy. Competition and facilitation on these stress gradients may control species distributions in the communities under canopies. We tested the following predictions: (1) interactions between understory species shift from competition to facilitation in habitats experiencing increasing stress from the center to the edge of canopy of a nurse plant, and (2) species distributions in understory communities are controlled by competitive interactions at the center of canopy, and facilitation at the edge of the canopy. We tested these predictions using a neighbor removal experiment under nurse trees growing in arid environments. Established individuals of each of four of the most common herbaceous species in the understory were used in the experiment. Two species were more frequent in the center of the canopy, and two species were more frequent at the edge of the canopy. Established individuals of each species were subjected to neighbor removal or control treatments in both canopy center and edge habitats. We found a shift from competitive to facilitative interactions from the center to the edge of the canopy. The shift in the effect of neighbors on the target species can help to explain species distributions in these canopies. Canopy‐dominant species only perform well in the presence of neighbors in the edge microhabitat. Competition from canopy‐dominant species can also limit the performance of edge‐dominant species in the canopy microhabitat. The shift from competition to facilitation under nurse plant canopies can structure the understory communities in extremely stressful environments.
Capture efficiency and trophic adaptations of a specialist and generalist predator: A comparison
Authors: Michálek Ondřej , Petráková Lenka , Pekár Stano 
Published: March 2017

AbstractSpecialist true predators are expected to exhibit higher capture efficiencies for the capture of larger and dangerous prey than generalist predators due to their possession of specialized morphological and behavioral adaptations. We used an araneophagous spider (Lampona murina) and a generalist spider (Drassodes lapidosus) as phylogenetically related model species and investigated their realized and fundamental trophic niches and their efficacy with respect to prey capture and prey handling. The trophic niche of both species confirmed that Lampona had a narrow trophic niche with a predominance of spider prey (including conspecifics), while the niche of Drassodes was wide, without any preference. DNA analysis of the gut contents of Lampona spiders collected in the field revealed that spiders form a significant part of its natural diet. Lampona captured significantly larger prey than itself and the prey captured by Drassodes. As concerns hunting strategy, Lampona grasped the prey with two pairs of legs possessing scopulae, whereas Drassodes immobilized prey with silk. Lampona possess forelegs equipped with scopulae and a thicker cuticle similar to other nonrelated araneophagous spiders. Lampona fed for a longer time and extracted more nutrients than Drassodes. We show that specialized behavioral and morphological adaptations altogether increase the hunting efficiency of specialists when compared to generalists.

AbstractMigrating long distances requires time and energy, and may interact with an individual's performance during breeding. These seasonal interactions in migratory animals are best described in populations with disjunct nonbreeding distributions. The black‐tailed godwit (Limosa limosa limosa), which breeds in agricultural grasslands in Western Europe, has such a disjunct nonbreeding distribution: The majority spend the nonbreeding season in West Africa, while a growing number winters north of the Sahara on the Iberian Peninsula. To test whether crossing the Sahara has an effect on breeding season phenology and reproductive parameters, we examined differences in the timing of arrival, breeding habitat quality, lay date, egg volume, and daily nest survival among godwits (154 females and 157 males), individually marked in a breeding area in the Netherlands for which wintering destination was known on the basis of resightings. We also examined whether individual repeatability in arrival date differed between birds wintering north or south of the Sahara. Contrary to expectation, godwits wintering south of the Sahara arrived two days earlier and initiated their clutch six days earlier than godwits wintering north of the Sahara. Arrival date was equally repeatable for both groups, and egg volume larger in birds wintering north of the Sahara. Despite these differences, we found no association between wintering location and the quality of breeding habitat or nest survival. This suggests that the crossing of an important ecological barrier and doubling of the migration distance, twice a year, do not have clear negative reproductive consequences for some long‐distance migrants.
Population assessment using multivariate time‐series analysis: A case study of rockfishes in Puget Sound

AbstractEstimating a population's growth rate and year‐to‐year variance is a key component of population viability analysis (PVA). However, standard PVA methods require time series of counts obtained using consistent survey methods over many years. In addition, it can be difficult to separate observation and process variance, which is critical for PVA. Time‐series analysis performed with multivariate autoregressive state‐space (MARSS) models is a flexible statistical framework that allows one to address many of these limitations. MARSS models allow one to combine surveys with different gears and across different sites for estimation of PVA parameters, and to implement replication, which reduces the variance‐separation problem and maximizes informational input for mean trend estimation. Even data that are fragmented with unknown error levels can be accommodated. We present a practical case study that illustrates MARSS analysis steps: data choice, model set‐up, model selection, and parameter estimation. Our case study is an analysis of the long‐term trends of rockfish in Puget Sound, Washington, based on citizen science scuba surveys, a fishery‐independent trawl survey, and recreational fishery surveys affected by bag‐limit reductions. The best‐supported models indicated that the recreational and trawl surveys tracked different, temporally independent assemblages that declined at similar rates (an average of −3.8% to −3.9% per year). The scuba survey tracked a separate increasing and temporally independent assemblage (an average of 4.1% per year). Three rockfishes (bocaccio, canary, and yelloweye) are listed in Puget Sound under the US Endangered Species Act (ESA). These species are associated with deep water, which the recreational and trawl surveys sample better than the scuba survey. All three ESA‐listed rockfishes declined as a proportion of recreational catch between the 1970s and 2010s, suggesting that they experienced similar or more severe reductions in abundance than the 3.8–3.9% per year declines that were estimated for rockfish populations sampled by the recreational and trawl surveys.
The spatial organization of ecosystem services in river‐floodplains
Authors: Tomscha Stephanie A. , Gergel Sarah E. , Tomlinson Matthew J. 
Published: March 2017

AbstractRiver‐floodplains are hotspots for many ecosystem services (ES), and thus, understanding how these services are spatially organized along river systems is essential. General principles from river‐floodplain ecology may provide guidance for understanding these spatial patterns, yet such concepts have rarely been incorporated into spatial assessments of ES. Using a lens of riverine concepts, we contrasted how floodplain ES capacity and diversity (orchard production, forage production, carbon storage, paddle route quality, fish capacity) vary with longitudinal river‐floodplain position. High spatial resolution aerial photography (2006) facilitated detection of floodplain features contributing to the production of ES. We also determined how river reach types are linked to production of ES. We found that ES capacity varied considerably with longitudinal position and reach type. Agricultural capacity was concentrated in lower reaches, high‐quality paddle routes in middle‐lower reaches, and fish capacity and carbon storage in upper reaches. Furthermore, the highest diversity of ES was concentrated in the lowland floodplain reaches. Our results suggest river‐floodplain concepts can improve spatial assessments of ES, increase our understanding of the relationships among biological features and ES, and thus help us better manage some of the key ES trade‐offs.
Fate of river‐transported carbon in china: implications for carbon cycling in coastal ecosystems
Authors: Gao Yang , Yang Tiantian , Wang Yafeng , Yu Guirui 
Published: March 2017

Abstract
Rivers play an important role in carbon (C) exchange between terrestrial and oceanic water bodies and the atmosphere. The aim of this study was to systematically quantify fluxes in riverine C export and C exchange in the air–sea interface of marine ecosystems in China. Results show that annual C transport from rivers to coastal ecosystems in China can reach up to 64.35 TgC, which accounts for approximately 4.8%–8.1% of global C transport from river systems. In the Bohai Sea, particulate inorganic carbon is the main form of C influx, and it can reach up to 20.79 TgC/yr. Conversely, dissolved inorganic carbon is the main form of C influx into the East China Sea, and it can reach up to 10.52 TgC/yr, which is 42.6% of the total annual C imported into the East China Sea. China's marine ecosystems including the Yellow Sea, the Bohai Sea, the East China Sea, and the South China Sea can absorb 65.06 TgC/yr from the atmosphere.
Effect of water and lipophilic alcohols or amines on the 4‐dodecylbenzenesulfonic acid‐catalyzed esterifications, trans‐esterifications, and amidations

Published: March 2017

4‐Dodecylbenzenesulfonic acid (DBSA) was employed in the esterification of oleic acid (OA) and the trans‐esterification of oleic oil (OO) with 1‐butanol as alcohol in the presence of various degrees of excess water. Under these conditions DBSA was found to be a highly active esterification catalyst regardless of excess water content, but was found to be a less effective for trans‐esterification reactions. Lipophilic alcohols of differing straight and branched C3‐6 chains were also tested on mixtures of OA/water (1:1) in DBSA‐catalyzed esterifications; OO/water (1:1) in trans‐esterifications; and OA/OO/water (1:1:1) in simultaneous esterifications and trans‐esterifications. While longer straight chain alcohols generally gave a two‐fold increase in yield of their corresponding alkyl oleates to 80%+, we observed a doubling from 30–50% to 60–95% of alkyl oleate yield for the OO/OA/water mixture. DBSA‐catalyzed amidations of OO and methyl oleate emulsions in water were conducted with 1‐butyl and 1‐heptyl amine where it was found that the more lipophilic the ester moiety the higher the yield of alkyl amide.Practical applications: The practical advantages of DBSA as catalyst are high conversions to the desired product along with its tolerance to high quantities of water, emulsified within the lipid material. A capacity to transform a range of substrates with varying lipophilic character in a range of condensation reactions. In addition, we demonstrate that esterification and trans‐esterification reactions could be performed simultaneous and in the presence of high quantities of water. This is of direct interest to the transformation of waste sources of lipids that often contain a mixture of triglycerides and free fatty acids in various concentrations, emulsified with waste water. Furthermore, we demonstrate that all of the value‐added products/co‐products can be separated by an effective and industrially relevant methodology, including recovery of the DBSA catalyst as well as the water and water soluble co‐products, such as glycerol.A 4‐Dodecylbenzenesulfonic acid (DBSA) is demonstrated to be an effective polyvalent catalyst for the recovery of aqueous emulsified lipids by conversion into value‐added products. DBSA proved to be a polyvalent catalyst showing high activity using a range of substrates, performing esterification, trans‐esterification, and amidations reactions efficiently despite the potential detrimental presence of high water loadings. The commercial incentive of our system is the phase separation of the product mixture into the converted lipids for use as biofuels and glycerol for resale as a fine chemical.
Re‐Thinking ‘The Different Perspectives That can be Used When Eliciting Preferences in Health’
Authors: Tsuchiya Aki , Watson Verity 
Published: March 2017

AbstractThe 2003 Health Economics paper by Dolan, Olsen, Menzel and Richardson on ‘An inquiry into the different perspectives that can be used when eliciting preferences in health’ presents a conceptual framework of six perspectives along two dimensions: preferences (personal, social, and socially inclusive personal) and context (ex ante and ex post). The objective of our paper is to re‐think this framework. We ask four questions concerning: the patient, or the user of the treatment; the payer of the treatment; the assessor of the value of treatment; and the timing of the illness and the nature of its risk. These questions refine the preference and context dimensions, and lead to the identification of perspectives not classified by the original framework. We propose an extended framework with five preferences (personal, non‐use, proxy, social, and socially inclusive personal) and five contexts (one of which is ex post and four ex ante): since two of these cells are empty, this results in 23 possible perspectives. Online Supplementary Information presents 11 of these more formally to clearly distinguish between them and uses monetary and non‐monetary (time trade‐off) valuation tasks as examples.

The impact of adverse health events on consumption: Understanding the mediating effect of income transfers, wealth, and health insurance
Authors: Babiarz Patryk , Yilmazer Tansel 
Published: March 2017

AbstractUsing data from the Panel Study of Income Dynamics for years 1999–2013, we investigate the impact of physical and mental illnesses on household consumption and financial status. In comparison to severe physical health problems, mental illnesses lead to larger decreases in labor income. Increases in public and private transfers following the onset of a mental illness do not completely offset the decline in labor income. Consequently, we find a significant decrease in consumption expenditures after the household head experiences a mental problem. On the other hand, public and private transfers and accumulated wealth offset the relatively smaller decline in labor income and enable households with severe physical problems to smooth their consumption. Health insurance helps to prevent larger drops in consumption after the onset of a mental health problem.

ABSTRACTBackgroundCyclic dinucleotides (CDNs) are bacterial intracellular messengers that have demonstrated antitumor activity in melanoma and breast tumors, although their role in immunotherapy of head and neck squamous cell cancers (HNSCCs) has not been well investigated.MethodsWe measured primary tumor growth rates, mechanism of antitumor activity, and efficacy of programmed death‐L1 blockade combinatorial therapy in SCCFVII tumor‐bearing C3H/HeOUJ mice undergoing intratumoral injections with RR‐cyclic‐di‐guanine (synthetic CDG), CDG (natural cyclic‐di‐guanine), R848 (TLR 7/8 agonist), or phosphate buffered saline (PBS, control).ResultsIntratumoral CDN treatment groups showed decreased tumor size and enhanced splenocyte Th1 response when compared to the PBS treatment control group (p < .05). The RR‐CDG tumor microenvironment showed upregulated interferon (IFN)‐γ+CD8+ and programmed death‐L1. Combining programmed death‐L1 blocking antibody with RR‐CDG induced regression of established tumors.ConclusionThis study demonstrates the antitumor effects of CDNs in a HNSCC cell line. These preclinical data strongly support the future clinical development of intratumoral CDN in patients with HNSCC. © 2017 Wiley Periodicals, Inc. Head Neck 39: 1086–1094, 2017
