Modelling the poroelastoplastic behaviour of soils subjected to internal erosion by suffusion
Authors: Rousseau Quentin , Sciarra Giulio , Gelet Rachel , Marot Didier 
Published: November 2019

AbstractGranular soils subjected to seepage flow may suffer suffusion, ie, a selective internal erosion. Extending the classical approach of poromechanics, we deduce a new form of the Clausius‐Duhem inequality accounting for dissipation due to suffusion, and we deduce restrictions on the constitutive laws of the soil. We suggest (a) a possible coupling between the seepage forces and the suffusion kinetics and (b) an extension of an existing elastoplastic model for the skeleton mechanical behaviour. Numerical integrations of the elastoplastic model are carried out under drained axisymmetric triaxial and oedometric conditions. As a result, we prove that the extended model is able to qualitatively reproduce the suffusion induced strains and the strength reduction experimentally observed. Predictions on the oedometric behaviour of suffusive soils are also provided.

AbstractAimQuantifying the relation between patient characteristics and care time and explaining differences in nursing time between wards.DesignAcademic hospital in the Netherlands. Six surgical wards, capacity 15–30 beds, 2012–2014.MethodsLinear mixed effects model to study the relation between patient characteristics and care time. Estimated marginal means to estimate baseline care time and differences between wards.ResultsNine patient characteristics significantly related to care time. Most required between 18 and 35 min extra, except “two or more IV/drip/drain” (8) and “one‐on‐one care” (156). Care time for minimum patient profile: 44–57 min and for average patient profile: 75–88 min. Sources of variation: nurse proficiency, patients, day‐to‐day variation within patients. The set of characteristics is short, simple and useful for planning and comparing workload. Explained variance up to 36%. Calculating estimated means per ward has not been done before. Nurse proficiency is an important factor.

AbstractAimTo determine the relationship between self‐concept and coping styles in patients with heart failure in an Iranian population.DesignThis study had a correlational design.MethodsIn this study, 100 HF patients hospitalized in the CCU and cardiac ward of Vali‐Asr Hospital of Birjand, Iran were selected by convenience sampling method. Two validated and reliable questionnaires including Cognitive Perception of Self‐Concept and the Coping Styles questionnaires were completed by each patient.ResultsThere were significant associations between emotion‐oriented and threat to self‐concept in total and physical sensation and self‐consistency dimensions. Also, a significant association was observed between avoidance‐oriented and threat to self‐concept in total and body sensation dimension (p < .05). There was no significant association between the problem‐oriented component and the threat to self‐concept in total and none of its dimensions. The challenge to self‐concept and its dimensions were not significantly related to any component of coping styles.
Palaeoenvironmental and hunting activity of the Upper Palaeolithic population in Western Transbaikalia: A case study on the Podzvonkaya Settlement, South Siberia

Published: November 2019

AbstractPaleontological data from Palaeolithic sites in the Transbaikal region are frequently interpreted from the viewpoint of palaeoenvironmental reconstruction. This research describes faunal material from one of the largest Initial Upper Palaeolithic settlements in Transbaikalia Podzvonkaya and the general characteristics of ancient human hunting activity there. The archaeological context of the faunal remains (located near hearths and in the kitchen midden) indicates the bones at the site are kitchen waste. The species composition indicates which species Podzvonkaya's inhabitants preferred to hunt. The largest number of remains belongs to horse, argali, bison, and Mongolian gazelle—animals that prefer open steppe and dry‐steppe landscapes. The results of a spore‐and‐pollen analysis of Podzvonkaya deposits reveal the domination of grass flora. The Tamir River valley could have been the habitat of the main target species, and ancient people probably hunted in the territory within the valley and in the valley's vicinity. Intraregional correlation with data on the species composition of the large mammals within other Palaeolithic remains of the Western Transbaikal region supports a conclusion regarding the identity of fauna at the final stage of the late Neopleistocene. Data from sites belonging to the same culture and period reveal identical prey lists, with certain preferences explained by site type (ie, long‐term base settlement or short‐term hunting camp).
Bioarchaeological investigation of an obstetric death at Huigou site (3900–2900 BC), Henan, China

Published: November 2019

AbstractHistorical documents record that many young women died of pregnancy, delivery, or related complications. However, such cases are rare archaeologically due to the limitations of archaeological materials. Here, we report the case of an adult female buried with an infant in the Neolithic graveyard of Huigou (Yangshao Culture, 3900–2900 BCE) in China's Henan Province. The remains of the infant were positioned between the lower legs of the adult. Both appear to have died during or shortly after delivery, as the estimated age of the infant is full term. The adult female's pubic symphysis was unusually long compared with a modern Chinese reference sample, a trait that increases the risk of dystocia in modern clinical cases. The pelvis also shows a hyperplastic lesion on the superior margin of the pubic symphysis that might reflect a prior difficult birth that was survived. Taken together this evidence suggests a history of obstetric problems that ultimately led to the death of the woman and her last child. Our reconstruction offers a glimpse of an ancient life, suggesting the difficulties this woman suffered in childbirth before her death and illustrating the insights that osteology can offer into obstetric experiences in the past.
Adolescent academic achievement: A model of social support and grit

Published: November 2019

AbstractGrit has been defined as passionate perseverance toward long‐term challenging goals and it is associated with various positive outcomes for youth, including academic achievement. However, less is known about these associations for the two facets of grit (i.e., perseverance of effort, consistency of interest) and few studies have examined the link between grit and perceived social support. The present study examined the group‐level demographic differences (i.e., gender, grade, socioeconomic status, and special education status) of grit in a high school sample (N = 1,077). In addition, direct associations between grit and perceived social support from multiple sources (i.e., teacher, classmate, parent) were examined, as well as a potential enhancing effect of social support as a moderator of the relation between grit and academic achievement. Results indicated positive associations among grit and its facets with social support from parents and classmates. Furthermore, the positive relation between grit and achievement was stronger for students reporting high social support from teachers, but not other sources (i.e., classmates, parents). Practical and theoretical implications for promoting student success are discussed.

AbstractObjectiveTo investigate the association between prophylactic bilateral oophorectomy and use of antidepressants in women with a family history of cancer.MethodsNationwide population‐based cohort study using Danish National Registries including women oophorectomized due to a family history of cancer (n = 2,002) and an age matched reference group (n = 18,018). Analyses were stratified by age at time of bilateral oophorectomy and use of hormone replacement therapy (HRT).ResultsWomen oophorectomized at age ≤ 45 years were more likely to use antidepressants from the first year after bilateral oophorectomy (OR = 1.34; 95 % CI: 1.08‐1.65) compared to the reference group. Women oophorectomized at age 46‐55 years and at age >55 years had no significantly increased use of antidepressants (OR = 0.90; 95 % CI: 0.68‐1.18 and OR = 1.14; 95 % CI: 0.81‐1.61). The increased use of antidepressants in women oophorectomized at age ≤ 45 years was limited to women treated with HRT (OR = 1.51; 95 % CI: 1.18‐1.94) whereas women oophorectomized at age ≤ 45 years not treated with HRT had no increased use of antidepressants (OR = 1.03; 95 % CI: 0.70‐1.51).ConclusionsWomen oophorectomized due to a family history of cancer at age ≤ 45 years were more likely to use antidepressants after bilateral oophorectomy. The increased use of antidepressants was limited to women treated with HRT. The study calls for further large‐scale studies to understand how bilateral oophorectomy and concomitant HRT affects risk of depression in women with a family history of cancer.

Published: November 2019

AbstractObjectiveSurvivors of multiple primary cancers (MPC) are at increased risk for poor health outcomes compared with survivors of single cancers. Using an adapted psychobehavioral stress‐response model, the study purpose was to identify pathways and individual risk factors associated with poor health outcomes in adults with MPC.MethodsAdult MPC survivors (N = 211) with first cancers (stages I‐III) diagnosed within 1 to 10 years were recruited via tumor registry. Employing a cross‐sectional design, established questionnaires were used to operationalize patient characteristics and theoretical constructs including perceived stress, psychological and behavioral responses, financial hardship, social role function, and physical health. Disease and treatment data were obtained via registry and medical records. Structural equation modeling (SEM) was performed to fit, test, and modify the hypothesized psychobehavioral model.ResultsFollowing measurement model refinement, an SEM linking self‐management behaviors, distress, financial hardship, and functional health demonstrated a good fit:χ2(200, N = 206) = 332.06,P< .01; Tucker‐Lewis index (TLI) = .95, comparative fit index (CFI) = .96, standardized root mean residual (SRMR) = .06, root‐mean‐square error of approximation (RMSEA) = .06. Less use of self‐management behaviors predicted higher distress which, in turn, predicted higher financial hardship; higher distress and financial hardship predicted poorer functional health. Several sociodemographic and personal factors predicted self‐management behaviors and distress.ConclusionsThe hypothesized stress‐response model was partially supported. Data supported pathways among self‐management behaviors, distress, financial hardship, and functional health. Self‐management and distress may represent modifiable intervention targets for MPC survivors. High body mass index (BMI), less education, greater neuroticism, and lower social support were associated with less use of self‐management behaviors and higher distress and should be further evaluated as potential markers of vulnerability.
Transnational migrants in Shanghai: residential spatial patterns and the underlying driving forces
Authors: Wang Chunlan , Li Chen , Wang Mark , Yang Shangguang 
Published: November 2019

AbstractWith a remarkably increasing number of transnational migrants settling down in China, their residential spatial distributions in Chinese cities have drawn significant academic attention. This paper investigates recent residential spatial patterns of transnational migrants in Shanghai and the underlying driving forces behind such choices. Based on China's sixth population census and our 30 focus group interviews in 30 neighbourhood committees, this paper finds that comparing with it in the semi‐colonial period, Mao's era and the early stages of China's economic reform, transnational migrants' residential spatial patterns in recent times in Shanghai are dispersed in every corner rather than concentrated in specific areas such as the old settlement sites and foreign expert buildings. The paper explains that such residential spatial fragmentation is largely driven by the combined forces of a neoliberal approach in the unique urban political economy in China, globalisation development, individual socioeconomic and demographic concerns and cultural factors.
Limitations of ion mobility spectrometry‐mass spectrometry for the relative quantification of architectural isomeric polymers: A case study
Authors: Liénard Romain , Duez Quentin , Grayson Scott M. , Gerbaux Pascal , Coulembier Olivier , De Winter Julien 
Published: November 2019

RationaleSince their discovery, cyclic polymers have attracted great interest because of their unique properties. Today, the preparation of these macrocyclic structures still remains a challenge for polymer chemists, and most of the preparation pathways lead to an inescapable contamination by linear by‐products. As the properties of the polymers are closely related to their structure, it is of prime importance to be able to assess the architectural purity of a sample.MethodsIn this work, the suitability of ion mobility spectrometry‐mass spectrometry (IMS‐MS) for the quantification of two isomers was investigated. A cyclic poly(L‐lactide) was prepared through photodimerization of its linear homologue. Since IMS‐MS can be used to differentiate cyclic polymer ions from their linear analogues because of their more compact three‐dimensional conformation, the present work envisaged the use of IMS‐MS for the quantification of residual linear polymers within the cyclic polymer sample.ResultsUsing the standard addition method to plot calibration curves, the fraction of linear contaminants in the sample was determined. By doing so, unrealistically high values of contamination were measured.ConclusionsThese results were explained by an ionization efficiency issue. This work underlines some intrinsic limitations when using IMS‐MS in the context of the relative quantification of isomers having different ionization efficiencies. Nevertheless, the linear‐to‐cyclic ratio can be roughly estimated by this method.
Containment control for distributed networks subject to multiplicative and additive noises with stochastic approximation–type protocols
Authors: Du Yingxue , Wang Yijing , Zuo Zhiqiang , Zhang Wentao 
Published: November 2019

SummaryThis paper is concerned with the stochastic containment control problem for distributed network with multiplicative and additive noises, in which the stochastic approximation technique is utilized. A major challenge, compared with the existing results with multiplicative and additive noises, is that the involving leaders are dynamically changing. It is shown that finite boundedness for dynamical leaders is of great importance for addressing the stochastic containment control issue. A suitable approach is proposed to handle multiplicative and additive noises based on the stochastic approximation, and some necessary/sufficient conditions are derived for mean square convergence with mild requirements. Furthermore, the convergence rates are studied for both dynamical leaders and static leaders scenarios. We conclude this paper by using two illustrative examples to verify the effectiveness of the theoretical results.
Reformulating ‘Holism' in hydropower decision‐making
Authors: Kang Kenneth 
Published: November 2019

AbstractThis paper investigates the necessary‐impossible paradox facing hydropower decision‐makers of the Mekong River Commission: that aspiring towards a holistic risk assessment is both socially useful and necessary, but also meaningless and impossible (because the future remains unknown). The thesis here is that to come to terms with this paradox, a Luhmannian inspired relational model offers superior analytical tools compared with an Aristotelian essentialist approach. This is because where the latter typically employs integrative approaches which attempt to show why through rational reasoning risk assessments are holistic, the former takes into account that holistic risk assessments are contingent on the observer, on an organisation's position within a network, and on the ‘temporal atoms' that mark the ‘time' of social systems. By employing a relational framework comprised ofvariation,selectionandretentionto capture this comparative sociology of the observer, the contribution here offers a radical reformulation of holism in hydropower decision‐making.
Time‐dependent material properties and reinforced beams behavior of two alkali‐activated types of concrete
Authors: Prinsse Silke , Hordijk Dick A. , Ye Guang , Lagendijk Paul , Luković Mladena 
Published: November 2019

AbstractThis paper presents an experimental study on the development of material properties over time (up to around 2 years) and the structural behavior of reinforced beams, for two types of alkali‐activated concrete (AAC). Compressive strength, flexural strength, tensile splitting strength, elastic modulus, and flexural behavior of reinforced beams are investigated. Tested material properties of AAC are compared with the properties of conventional concrete, as predicted by Eurocode. For the mixes of AAC and the conventional concretes with the same 28 days compressive strength, flexural and tensile splitting strength at 28 days are found to be similar, whereas the elastic moduli of AAC mixtures is up to 30% lower than those of conventional concrete. Related to the long term behavior, after 28 days moist‐curing and subsequently exposing AAC specimens to laboratory conditions (50% RH/20°C), a reduction of flexural strength, tensile splitting strength and elastic modulus, is observed. Structural behavior of the reinforced AAC beams in four‐point bending test seems not to be affected significantly by the observed decrease in material properties, and is found to be similar to that of conventional concrete beams. The acquired results indicate that the observed decrease of material properties over time might be related to drying (moisture loss). However, more research is needed to understand the phenomenon, especially related to the aimed structural application and safe upscaling of AAC.
Mode decomposition approach in robust control design for horizontal axis wind turbines
Authors: Poureh Ali , Nobakhti Amin 
Published: November 2019

AbstractA robust multivariable strategy for pitch and torque control design of variable‐speed variable‐pitch wind turbines in the full load region is introduced in this paper. The pitch and torque control loops that share the tracking and active damping of drivetrain torsional mode objectives are designed simultaneously using a novel decomposition scheme. This permits the systematic design of robust multivariable controllers for wind turbines in a manner that facilitates industrial application. We achieve this by making the process of weighting function design fast, intuitive, and simple and by giving the designer a clear insight on the compromising aspects of the various control system objectives. FAST simulation is used to demonstrate application of the method.
ABJM quantum spectral curve at twist 1: algorithmic perturbative solution
Authors: Lee R.N. , Onishchenka A.I. 
Published: November 2019

Abstract
We present an algorithmic perturbative solution of ABJM quantum spectral curve at twist 1 in sl (2) sector for arbitrary spin values, which can be applied to, in principle, arbitrary order of perturbation theory. We determined the class of functions- products of rational functions in spectral parameter with sums of Baxter polynomials and Hurwitz functions - closed under elementary operations, such as shifts and partial fractions, as well as differentiation. It turns out, that this class of functions is also sufficient for finding solutions of inhomogeneous Baxter equations involved. For the latter purpose we present recursive construction of the dictionary for the solutions of Baxter equations for given inhomogeneous parts. As an application of the proposed method we present the computation of anomalous dimensions of twist 1 operators at six loop order. There is still a room for improvements of the proposed algorithm related to the simplifications of arising sums. The advanced techniques for their reduction to the basis of generalized harmonic sums will be the subject of subsequent paper. We expect this method to be generalizable to higher twists as well as to other theories, such as $$ \mathcal{N} $$

Duality walls in the 4d $$ \mathcal{N} $$ = 2 SU(N) gauge theory with 2N flavours

Abstract
S-duality domain walls are extended objects in supersymmetric gauge theories with several rich physical properties. This paper focuses on 3d $$ \mathcal{N} $$
N
= 2 gauge theories associated with S-duality walls in the 4d $$ \mathcal{N} $$
N
= 2 SU(N ) gauge theory with 2N flavours. The theories associated with multiple duality walls are constructed by gluing together a basic building block, which is the theory associated with a single duality wall. We propose the prescription for gluing many copies of such a basic building block together as well as present the prescription for self-gluing. A number of dualities between such theories are discovered and studied using the supersymmetric index. This work generalises the notion of the S-fold theory, which has been so far studied extensively in the context of duality walls in the 4d super-Yang-Mills theory, to the theory with lower amounts of supersymmetry.
