Applying camera traps to detect and monitor introduced mammals on oceanic islands
Authors: Lamelas-López Lucas , Salgado Iván 
Published: October 2020

AbstractThe introduction of mammal predators has been a major cause of species extinctions on oceanic islands. Eradication is only possible or cost-effective at early stages of invasion, before introduced species become abundant and widespread. Although prevention, early detection and rapid response are the best management strategies, most oceanic islands lack systems for detecting, responding to and monitoring introduced species. Wildlife managers require reliable information on introduced species to guide, assess and adjust management actions. Thus, a large-scale and long-term monitoring programme is needed to evaluate the management of introduced species and the protection of native wildlife. Here, we evaluate camera trapping as a survey technique for detecting and monitoring introduced small and medium-sized terrestrial mammals on an oceanic island, Terceira (Azores). Producing an inventory of introduced mammals on this island required a sampling effort of 465 camera-trap days and cost EUR 2,133. We estimated abundance and population trends by using photographic capture rates as a population index. We also used presence/absence data from camera-trap surveys to calculate detection probability, estimated occupancy rate and the sampling effort needed to determine species absence. Although camera trapping requires large initial funding, this is offset by the relatively low effort for fieldwork. Our findings demonstrate that camera trapping is an efficient survey technique for detecting and monitoring introduced species on oceanic islands. We conclude by proposing guidelines for designing monitoring programmes for introduced species.

AbstractBackgroundCognition is commonly affected in brain disorders. Non-invasive brain stimulation (NIBS) may have procognitive effects, with high tolerability. This meta-analysis evaluates the efficacy of transcranial magnetic stimulation (TMS) and transcranial Direct Current Stimulation (tDCS) in improving cognition, in schizophrenia, depression, dementia, Parkinson's disease, stroke, traumatic brain injury, and multiple sclerosis.MethodsA PRISMA systematic search was conducted for randomized controlled trials. Hedges'gwas used to quantify effect sizes (ES) for changes in cognition after TMS/tDCSv.sham. As different cognitive functions may have unequal susceptibility to TMS/tDCS, we separately evaluated the effects on: attention/vigilance, working memory, executive functioning, processing speed, verbal fluency, verbal learning, and social cognition.ResultsWe included 82 studies (n= 2784). For working memory, both TMS (ES = 0.17,p= 0.015) and tDCS (ES = 0.17,p= 0.021) showed small but significant effects. Age positively moderated the effect of TMS. TDCS was superior to sham for attention/vigilance (ES = 0.20,p= 0.020). These significant effects did not differ across the type of brain disorder. Results were not significant for the other five cognitive domains.ConclusionsOur results revealed that both TMS and tDCS elicit a small trans-diagnostic effect on working memory, tDCS also improved attention/vigilance across diagnoses. Effects on the other domains were not significant. Observed ES were small, yet even slight cognitive improvements may facilitate daily functioning. While NIBS can be a well-tolerated treatment, its effects appear domain specific and should be applied only for realistic indications (i.e. to induce a small improvement in working memory or attention).
Relationships in late life from a personal communities approach: perspectives of older people in Chile
Authors: Torrejon Maria-Jose , Martin-Matthews Anne 
Published: October 2020

AbstractAlthough the literature on social capital, social support and social networks uses the concept of emotional support, studies rarely recognise nuances of the emotional relationships in late life. Using a personal communities framework, we examine the subjective meaning of family and friendship ties that form the network of emotionally close relationships of a cohort of Chilean people between 60 and 74 years of age. Chile is an interesting case to investigate personal communities, as the country is facing both a rapid process of population ageing and the consequences of abrupt socio-cultural changes triggered by a military government. We conducted qualitative semi-structured interviews using personal communities diagrams that enabled study participants to reflect on what and how different types of personal ties were important to them. Data analysis included thematic analysis of interview transcripts and classification of identified personal communities using Pahl and Spencer's typology. The personal communities framework proved useful in capturing the composition of older people's networks of close relationships and in reflecting the diverse ways different ties are relevant in late life. We further developed a complementary typology based on the distinction between ‘clustered’ and ‘hierarchical’ personal communities. This complementary typology adds a cultural dimension to understand better emotional closeness in late life in a context of rapid socio-cultural changes affecting levels of social trust.
Forward and backward transfer of sentence processing cues in English and Mandarin Chinese: A call for approximate replication of Liu, Bates, and Li (1992) and Su (2001)
Authors: Skalicky Stephen , Chen Victoria 
Published: October 2020

AbstractThe Competition Model has served as a functional explanation of cross-linguistic influence and transfer for more than 30 years. A large number of studies have used the Competition Model to frame investigations of sentence processing strategies in different types of bilingual and multilingual speakers. Among the different bilingual speakers investigated, Mandarin Chinese and English bilinguals represent a clear testing ground for the claims of the Competition Model. This is because of purportedly stark contrasts in sentence processing strategies between the two languages. Previous studies investigating sentence processing strategies of English L2 and Mandarin L2 bilinguals suggests forward transfer of L1 cues to the L2, moderated by L2 proficiency. In this paper, we argue for replication of two of these studies, namely Liu, Bates, and Li (1992) and Su (2001). These studies continue to be cited today as evidence of differences between English and Mandarin sentence processing strategies which is in turn taken as support for the predictions of the Competition Model. However, both studies presented methodological limitations in terms of measures of proficiency, participant and stimuli selection, and the statistical analysis. We suggest approximate replication of both of these studies and provide suggestions for how such replications might be conducted.
Relativistic cavity, possibilities, and advantages

AbstractThe relativistic mirror (RM) is an interesting subject which introduced in the nonlinear regime of the laser–plasma interaction. Reflection of counter-propagating probe pulse from relativistic flying mirror has some excellent features, such as frequency up-shifting and compressing by a factor of 4γ2. In the high-intensity laser–plasma interaction, sometimes a sequence of RMs creates. For example, electron density cusps generate in the nonlinear laser wakefield generation or flying electron sheaths create in the blown-out regime of the laser foil interaction. Under these circumstances, the second counter-propagated seed (probe) pulse can be reflected back and forth between two or more successive RMs. This structure may be used as a relativistic cavity (RECA). Amplification and threshold conditions for the gain medium and pumping rate in the RECA are obtained, and it is shown that amplification can be started from background simultaneous emission (without seed pulse). A new feature of RECA is it's bidirectional (two frequencies) characteristic. Thereupon, the gain process can be implemented on the two different transitions in this bidirectional gain structure. In the RECA, driver pulse may be assembled as a pumping operation, and background plasma medium with high degree ionized substances is a good candidate for gain medium in the UV or X-ray regions. In this paper, we propose a new all-optical cavity for the generation of the ultrashort laser pulse in the UV or X-ray regions.

Published: October 2020

AbstractThe Adult Attachment Interview (AAI) is a widely used measure in developmental science that assesses adults’ current states of mind regarding early attachment-related experiences with their primary caregivers. The standard system for coding the AAI recommends classifying individuals categorically as having an autonomous, dismissing, preoccupied, or unresolved attachment state of mind. However, previous factor and taxometric analyses suggest that: (a) adults’ attachment states of mind are captured by two weakly correlated factors reflecting adults’ dismissing and preoccupied states of mind and (b) individual differences on these factors are continuously rather than categorically distributed. The current study revisited these suggestions about the latent structure of AAI scales by leveraging individual participant data from 40 studies (N = 3,218), with a particular focus on the controversial observation from prior factor analytic work that indicators of preoccupied states of mind and indicators of unresolved states of mind about loss and trauma loaded on a common factor. Confirmatory factor analyses indicated that: (a) a 2-factor model with weakly correlated dismissing and preoccupied factors and (b) a 3-factor model that further distinguished unresolved from preoccupied states of mind were both compatible with the data. The preoccupied and unresolved factors in the 3-factor model were highly correlated. Taxometric analyses suggested that individual differences in dismissing, preoccupied, and unresolved states of mind were more consistent with a continuous than a categorical model. The importance of additional tests of predictive validity of the various models is emphasized.
Independent dominating sets in graphs of girth five
Authors: Harutyunyan Ararat , Horn Paul , Verstraete Jacques 
Published: October 2020

AbstractLet
$\gamma(G)$
and
$${\gamma _ \circ }(G)$$
denote the sizes of a smallest dominating set and smallest independent dominating set in a graph G, respectively. One of the first results in probabilistic combinatorics is that if G is an n-vertex graph of minimum degree at least d, then$$\begin{equation}\gamma(G) \leq \frac{n}{d}(\log d + 1).\end{equation}$$In this paper the main result is that if G is any n-vertex d-regular graph of girth at least five, then$$\begin{equation}\gamma_(G) \leq \frac{n}{d}(\log d + c)\end{equation}$$for some constant c independent of d. This result is sharp in the sense that as
$d \rightarrow \infty$
, almost all d-regular n-vertex graphs G of girth at least five have$$\begin{equation}\gamma_(G) \sim \frac{n}{d}\log d.\end{equation}$$Furthermore, if G is a disjoint union of
${n}/{(2d)}$
complete bipartite graphs
$K_{d,d}$
, then
${\gamma_\circ}(G) = \frac{n}{2}$
. We also prove that there are n-vertex graphs G of minimum degree d and whose maximum degree grows not much faster than d log d such that
${\gamma_\circ}(G) \sim {n}/{2}$
as
$d \rightarrow \infty$
. Therefore both the girth and regularity conditions are required for the main result.
Graphene-based microwave coaxial antenna for microwave ablation: thermal analysis
Authors: Uzman Burak , Yilmaz Adem , Acikgoz Hulusi , Mittra Raj 
Published: October 2020

AbstractIn this study, the problem of backward heating in microwave ablation technique is examined and an electromagnetic solution based on the use of high impedance graphene material is presented for its mitigation. In this context, a one-atom-thick graphene layer is added on the coaxial double slot antenna. In addition to the electromagnetic behavior, thermal effects caused by the graphene-covered antenna are emphasized. The graphene's conductivity being highly dependent on its chemical potential and the relaxation time, a parametric study is performed to determine a range of tolerances within which the graphene-coated antenna outperform a typical graphene-free antenna. The range of values is found to be 0 < μc < 0.5 eV and τ < 0.4 ps, for the chemical potential and the relaxation time, respectively. The backward heating problem being prevented, the ablation region is ensured to be spherical around the tip of the antenna. Effects of the graphene layer to the heat dissipation in the tissue, the necrotic tissue ratio (damage to the cancerous tissue of the caused by electromagnetic energy), and the treatment time using the coaxial double slot antenna were examined. The results show that the heat dissipation is concentrated around the slots (region of cancerous tissue) and a higher necrotic tissue ratio can be achieved with a graphene-covered double slot antenna in a shorter time.
Longitudinal associations between adolescents’ trajectory membership of depressive symptoms and suicidality in young adulthood: a 10-year cohort of Chinese Wenchuan earthquake survivors

Published: October 2020

Abstract

Aims
Previous studies regarding associations between depressive symptoms and suicidality (suicidal ideation, plans and attempts) have usually employed a variable-centred approach, without considering the individual variance in time-varying changes of depressive symptoms. Through 10-year follow-up of a large cohort of Chinese adolescents exposed to the 2008 Wenchuan earthquake, this study examined whether individual variance in depressive symptoms during the early phases post-earthquake could generate different suicidality outcomes in young adulthood.

Methods
A total of 1357 Chinese adolescents exposed to the Wenchuan earthquake were surveyed on depressive symptoms and other variables at 6, 18 and 30 months post-earthquake. In total, 799 participants responded to the 10-year follow-up and completed an online survey covering suicidality and other variables. The analytic sample was 744 participants who had valid data on depressive symptoms and suicidality. Data were analysed using logistic regressions.

Results
Prevalence estimates of past-year suicidal ideation, suicide plans and suicide attempts measured at 10 years post-earthquake were found to be 10.8%, 7.3% and 3.0%, respectively. Five trajectories of depressive symptoms were classified: resistance (54.4%), chronicity (13.3%), recovery (10.4%), delayed dysfunction (12.0%) and relapsing/remitting (10.0%). After controlling for covariates, whole-sample regressions revealed only the relapsing/remitting depressive trajectory remained significantly predictive of suicidality. Moreover, males not females in the chronic group were more likely to have suicide plans.

Conclusions
The findings highlight the importance of detecting disaster survivors with different trajectories of mental status and providing with them individualised and effective mental health services, to decrease their risk of suicidality in the future.
How does the Leader’s Centrality affect Team Performance Assessment? Testing the Role of Leader’s Satisfaction
Authors: Alves Marta Pereira , Dimas Isabel Dórdio , Lourenço Paulo Renato 
Published: October 2020

AbstractThe study aims to test how the association between leader’s centrality (outdegree and betweenness) in the group network, considering both workflow and friendship ties between leader and members, and the perception of team performance is mediated by the leader’s satisfaction with the team. The research included a total of 74 formal leaders of organizational teams from several organizations. Total, direct and indirect effects were calculated through the estimation of an OLS regression-based mediation model, controlling for team size. Results revealed that only leader’s outdegree and betweenness centrality in the team friendship network positively predicted the leader’s perception of team performance. In contrast to the predictions, a significant negative indirect effect of outdegree centrality of the leader within the team workflow network on the evaluation of group performance through leader’s satisfaction was observed. Also, both leader´s outdegree and betweenness centrality levels in the friendship network were shown to have a positive effect on leader’s assessment of team performance through leader’s satisfaction with the team. Overall, findings point to the negative effects of leader’s centrality in the workflow team network and the positive effects of leader’s centrality in the friendship team network on his/her attitudes toward the team. The effects of the more or less central position of the leader within each of the group networks are discussed.

AbstractAnnual grass weeds reduce profits of wheat farmers in the Pacific Northwest. The very-long-chain fatty acid elongase (VLCFA)-inhibiting herbicides S-metolachlor and dimethenamid-P could expand options for control of annual grasses but are not registered in wheat, because of crop injury. We evaluated a safener, fluxofenim, applied to wheat seed for protection of 19 soft white winter wheat varieties from S-metolachlor, dimethenamid-P, and pyroxasulfone herbicides; investigated the response of six varieties (UI Sparrow, LWW 15-72223, UI Magic CL+, Brundage 96, UI Castle CL+, and UI Palouse CL+) to incremental doses of fluxofenim; established the fluxofenim dose required to optimally protect the varieties from VLCFA-inhibiting herbicides; and assessed the impact of fluxofenim dose on glutathione S-transferase (GST) activity in three wheat varieties (UI Sparrow, Brundage 96, and UI Castle CL+). Fluxofenim increased the biomass of four varieties treated with S-metolachlor or dimethenamid-P herbicides and one variety treated with pyroxasulfone. Three varieties showed tolerance to the herbicides regardless of the fluxofenim treatment. Estimated fluxofenim doses resulting in 10% biomass reduction of wheat ranged from 0.55 to 1.23 g ai kg−1 seed. Fluxofenim doses resulting in 90% increased biomass after treatment with S-metolachlor, dimethenamid-P, and pyroxasulfone ranged from 0.07 to 0.55, 0.09 to 0.73, and 0.30 to 1.03 g ai kg−1 seed, respectively. Fluxofenim at 0.36 g ai kg−1 seed increased GST activity in UI Castle CL+, UI Sparrow, and Brundage 96 by 58%, 30%, and 38%, respectively. These results suggest fluxofenim would not damage wheat seedlings up to three times the rate labeled for sorghum, and fluxofenim protects soft white winter wheat varieties from S-metolachlor, dimethenamid-P, or pyroxasulfone injury at the herbicide rates evaluated.
Calibrating Simple Climate Models to Individual Earth System Models: Lessons Learned From Calibrating Hector
Authors: Dorheim Kalyn , Link Robert , Hartin Corinne , Kravitz Ben , Snyder Abigail 
Published: October 2020

AbstractSimple climate models (SCMs) are computationally efficient and capable of emulating global mean output of more complex Earth system models (ESMs). In doing so, SCMs can play a critical role in climate research as stand‐ins for the computationally more expensive models, especially in studies involving low, spatial, and/or temporal resolution, providing more computationally efficient sources of climate data. Here we use Hector v2.5.0 to emulate the multiforcing historical and RCP scenario output for 31 concentration and seven emission‐driven ESMs. When calibrating Hector, sufficient calibration data must be used to constrain the model; otherwise, climate and/or carbon parameters affecting physical processes may be able to trade off with one another, allowing for solutions to use physically unreasonable fitted parameter values as well as limiting the application of the SCM as an emulator. We also present a novel methodology that uses the ESM range as a calibration data, which can be adopted when faced with missing variable output from a specific model.
MARHYS (MARine HYdrothermal Solutions) Database: A Global Compilation of Marine Hydrothermal Vent Fluid, End Member, and Seawater Compositions
Authors: Diehl Alexander , Bach Wolfgang 
Published: October 2020

AbstractWe introduce a database of hydrothermal vent fluid compositions extracted from peer‐reviewed publications. The database includes general fluid parameters (e.g., temperature, salinity, and pH) as well as major‐, minor‐, and trace‐element concentrations (including rare earth elements) of dissolved cations, anions, reduced carbon compounds, and gases. In addition, isotopic compositions of elements and molecules are included. Each parameter in the database is given in a uniform unit and enables direct intercomparison of data from the incorporated sources. The database provides detailed information about geographic location, the date of sampling, and a broad set of supplementary information that enables clear identification of each individual sample and the original data source. This type of metadata was used to merge compositional data for discrete vent fluid samples that originate from different publications. Hence, the database provides a more complete set of compositional parameters than the original sources do. To facilitate operability, the database is provided as ®Excel sheet, which enables users to visualize, sort, filter, and evaluate the database in a straightforward way. The sample information metadata enables extraction of available vent fluid data for specific regions, tectonic settings, host rock types, etc. The database will be a useful tool in determining (1) mechanisms that set fluid chemistry, as well as (2) regional and global geochemical fluxes across the seabed. To demonstrate the extent of the database, we examine the global distribution of magnesium, chloride, and sodium concentrations in vent fluid samples that are incorporated in MARHYS Database.
