Design, Preparation and Performance Study of On-Chip Flow-Through Amperometric Sensors with an Integrated Ag/AgCl Reference Electrode
Authors: Zhang He , Chuai Rongyan , Li Xin , Zhang Bing
Published: March 2018

To improve the reference potential stability of on-chip amperometric sensors, we propose a novel integrated Ag/AgCl reference electrode structure. This structure can refresh the saturated potassium chloride filling solution surrounding the Ag/AgCl electrode. We then designed a flow-through amperometric sensor and a multilayer microfluidic chip based on the integrated reference electrode. In order to improve the detection signal strength of the flow-through sensor, a numerical simulation model was established. The simulation results showed that a combination of (1) using a step-type detection cell structure that maintains micro-channel width while reducing micro-channel height, and (2) controlling the sample flow rate to limit the mass transfer of the sensor surface effectively, improves the detection signal strength. The step-type detection cell structure had dimensions of 200 μm × 200 μm × 100 μm (length × width × height), and the electroosmotic flow driving voltage was 120 V/cm. Finally, successful trace detection of Mg2+ and Pb2+ in the water was achieved using the amperometric sensor and microfluidic chip: detection limits were 5 μmol/L and 84 μmol/L. The preparation of an on-chip flow-through amperometric sensor with an integrated Ag/AgCl reference electrode will facilitate improved portability of microfluidic detection technology.

Published: March 2018

The color expression of anthocyanins can be affected by a variety of environmental factors and structural characteristics. Anthocyanin acylation (type and number of acids) is known to be key, but the influence of acyl isomers (with unique stereochemistries) remains to be explored. The objective of this study was to investigate the effects of cis–trans configuration of the acylating group on the spectral and colorimetric properties of anthocyanins. Petunidin-3-rutinoside-5-glucoside (Pt-3-rut-5-glu) and Delphinidin-3-rutinoside-5-glucoside (Dp-3-rut-5-glu) and their cis and trans coumaroylated derivatives were isolated from black goji and eggplant, diluted in pH 1–9 buffers, and analyzed spectrophotometrically (380–700 nm) and colorimetrically (CIELAB) during 72 h of storage (25 °C, dark). The stereochemistry of the acylating group strongly impacted the spectra, color, and stability of the Dp and Pt anthocyanins. Cis acylated pigments exhibited the greatest λmax in all pH, as much as 66 nm greater than their trans counterparts, showing bluer hues. Cis acylation seemed to reduce hydration across pH, increasing color intensity, while trans acylation generally improved color retention over time. Dp-3-cis-p-cou-rut-5-glu exhibited blue hues even in pH 5 (C*ab = 10, hab = 256°) where anthocyanins are typically colorless. Cis or trans double bond configurations of the acylating group affected anthocyanin spectral and stability properties.

Published: March 2018

A series of 3-benzoyl imidazo[1,2-a]pyrimidines, obtained from N-heteroarylformamidines in good yields, was tested in silico and in vitro for binding and inhibition of seven Candida species (Candida albicans (ATCC 10231), Candida dubliniensis (CD36), Candida glabrata (CBS138), Candida guilliermondii (ATCC 6260), Candida kefyr, Candida krusei (ATCC 6358) and Candida tropicalis (MYA-3404)). To predict binding mode and energy, each compound was docked in the active site of the lanosterol 14α-demethylase enzyme (CYP51), essential for fungal growth of Candida species. Antimycotic activity was evaluated as the 50% minimum inhibitory concentration (MIC50) for the test compounds and two reference drugs, ketoconazole and fluconazole. All test compounds had a better binding energy (range: −6.11 to −9.43 kcal/mol) than that found for the reference drugs (range: 48.93 to −6.16 kcal/mol). In general, the test compounds showed greater inhibitory activity of yeast growth than the reference drugs. Compounds 4j and 4f were the most active, indicating an important role in biological activity for the benzene ring with electron-withdrawing substituents. These compounds show the best MIC50 against C. guilliermondii and C. glabrata, respectively. The current findings suggest that the 3-benzoyl imidazo[1,2-a]pyrimidine derivatives, herein synthesized by an accessible methodology, are potential antifungal drugs.

Published: March 2018

Sulfonated cellulose beads were prepared by oxidation of Cladophora nanocellulose to 2,3-dialdehyde cellulose followed by sulfonation using bisulfite. The physicochemical properties of the sulfonated beads, i.e., high surface area, high degree of oxidation, spherical shape, and the possibility of tailoring the porosity, make them interesting candidates for the development of immunosorbent platforms, including their application in extracorporeal blood treatments. A desired property for materials used in such applications is blood compatibility; therefore in the present work, we investigate the hemocompatibility of the sulfonated cellulose beads using an in vitro whole blood model. Complement system activation (C3a and sC5b-9 levels), coagulation activation (thrombin-antithrombin (TAT) levels) and hemolysis were evaluated after whole blood contact with the sulfonated beads and the results were compared with the values obtained with the unmodified Cladophora nanocellulose. Results showed that neither of the cellulosic materials presented hemolytic activity. A marked decrease in TAT levels was observed after blood contact with the sulfonated beads, compared with Cladophora nanocellulose. However, the chemical modification did not promote an improvement in Cladophora nanocellulose hemocompatibility in terms of complement system activation. Even though the sulfonated beads presented a significant reduction in pro-coagulant activity compared with the unmodified material, further modification strategies need to be investigated to control the complement activation by the cellulosic materials.

Authors: Fu Hua , Hu Jing , Zhang Min , Wang Yuerong , Zhang Hongyang , Hu Ping
Published: March 2018

For enrichment and separation of cis-diol-containing compounds from biomatrix, a new type of magnetic nanoparticles named MS-48-PBSC, whichwas facilely prepared in a one-step heterogeneous reaction. The morphology results demonstrated that the MS-48-PBSC was a spherical nanomaterial containing a core of silica-coated magnetic particle with a diameter of about 200 nm, and a cover layer of mesoporous silica with a thickness of approximate 50 nm. The characterization results showed that MS-48-PBSC presented a pore size of 4.2 nm, a surface area of 548 m2·g−1, and a pore volume of 0.30 cm3·g−1. The MS-48-PBSC also exhibited magnetism of 42 emu·g−1 that contributed to the easy separation of magnetic nanomaterial within 30 s from the matrix with the aid of the external magnetic field. In addition, the MS-48-PBSC exhibited high adsorption capacity for adenosine, xanthosine, uridine, sialic acid, and teicoplanin with 0.60, 0.51, 0.42, 0.75, and 1.26 mg/g, respectively, and showed a high selectivity for the cis-diol structure compounds, relative to interferences of bovine serum albumin, guanine, uric acid, and xanthine. The recoveries of adenosine, xanthosine, uridine, sialic acid, and teicoplanin were 71.8–114.1% with relative standard deviation (RSD) ≤ 8.6%, and the enrichment factors of them were 8–11. MS-48-PBSC exhibited quick separation capability from matrix, high adsorption capacity and size exclusion for bovine serum albumin, which could meet the requirements of separation and enrichment for substances with a cis-diol structure.
Phase Transition-Driven Nanoparticle Assembly in Liquid Crystal Droplets

Published: March 2018

When nanoparticle self-assembly takes place in an anisotropic liquid crystal environment, fascinating new effects can arise. The presence of elastic anisotropy and topological defects can direct spatial organization. An important goal in nanoscience is to direct the assembly of nanoparticles over large length scales to produce macroscopic composite materials; however, limitations on spatial ordering exist due to the inherent disorder of fluid-based methods. In this paper we demonstrate the formation of quantum dot clusters and spherical capsules suspended within spherical liquid crystal droplets as a method to position nanoparticle clusters at defined locations. Our experiments demonstrate that particle sorting at the isotropic–nematic phase front can dominate over topological defect-based assembly. Notably, we find that assembly at the nematic phase front can force nanoparticle clustering at energetically unfavorable locations in the droplets to form stable hollow capsules and fractal clusters at the droplet centers.

Published: March 2018

In craniofacial tissue regeneration, the current gold standard treatment is autologous bone grafting, however, it presents some disadvantages. Although new alternatives have emerged there is still an urgent demand of biodegradable scaffolds to act as extracellular matrix in the regeneration process. A potentially useful element in bone regeneration is strontium. It is known to promote stimulation of osteoblasts while inhibiting osteoclasts resorption, leading to neoformed bone. The present paper reports the preparation and characterization of strontium (Sr) containing hybrid scaffolds formed by a matrix of ionically cross-linked chitosan and microparticles of poly(ε-caprolactone) (PCL). These scaffolds of relatively facile fabrication were seeded with osteoblast-like cells (MG-63) and human bone marrow mesenchymal stem cells (hBMSCs) for application in craniofacial tissue regeneration. Membrane scaffolds were prepared using chitosan:PCL ratios of 1:2 and 1:1 and 5 wt % Sr salts. Characterization was performed addressing physico-chemical properties, swelling behavior, in vitro biological performance and in vivo biocompatibility. Overall, the composition, microstructure and swelling degree (≈245%) of scaffolds combine with the adequate dimensional stability, lack of toxicity, osteogenic activity in MG-63 cells and hBMSCs, along with the in vivo biocompatibility in rats allow considering this system as a promising biomaterial for the treatment of craniofacial tissue regeneration.

Multi-Target Angle Tracking Algorithm for Bistatic Multiple-Input Multiple-Output (MIMO) Radar Based on the Elements of the Covariance Matrix
Authors: Zhang Zhengyan , Zhang Jianyun , Zhou Qingsong , Li Xiaobo
Published: March 2018

In this paper, we consider the problem of tracking the direction of arrivals (DOA) and the direction of departure (DOD) of multiple targets for bistatic multiple-input multiple-output (MIMO) radar. A high-precision tracking algorithm for target angle is proposed. First, the linear relationship between the covariance matrix difference and the angle difference of the adjacent moment was obtained through three approximate relations. Then, the proposed algorithm obtained the relationship between the elements in the covariance matrix difference. On this basis, the performance of the algorithm was improved by averaging the covariance matrix element. Finally, the least square method was used to estimate the DOD and DOA. The algorithm realized the automatic correlation of the angle and provided better performance when compared with the adaptive asymmetric joint diagonalization (AAJD) algorithm. The simulation results demonstrated the effectiveness of the proposed algorithm. The algorithm provides the technical support for the practical application of MIMO radar.
Simultaneous Detection of Two Chemicals Using a TE20-Mode Substrate-Integrated Waveguide Resonator
Authors: Salim Ahmed , Memon Muhammad , Lim Sungjoon
Published: March 2018

Microwave resonators working as sensors can detect only a single analyte at a time. To address this issue, a TE20-mode substrate-integrated waveguide (SIW) resonator is exploited, owing to its two distinct regions of high-intensity electric fields, which can be manipulated by loading two chemicals. Two microfluidic channels with unequal fluid-carrying capacities, engraved in a polydimethylsiloxane (PDMS) sheet, can perturb the symmetric electric fields even if loaded with the two extreme cases of dielectric [ethanol (E), deionized water (DI)] and [deionized water, ethanol]. The four layers of the sandwiched structure considered in this study consisted of a top conductive pattern and a bottom ground, both realized on a Rogers RT/Duroid 5880. PDMS-based channels attached with an adhesive serve as the middle layers. The TE20-mode SIW with empty channels resonates at 8.26 GHz and exhibits a −25 dB return loss with an unloaded quality factor of Q ≈ 28. We simultaneously load E and DI and demonstrate the detection of the four possible combinations: [E, DI], [DI, E], [E, E], and [DI, DI]. The performance of our proposed method showed increases in sensitivity (MHz/εr) of 7.5%, 216%, and 1170% compared with three previously existing multichannel microwave chemical sensors.
From Viability to Sustainability: The Contribution of the Viable Systems Approach (VSA)
Authors: Formisano Vincenzo , Quattrociocchi Bernardino , Fedele Maria , Calabrese Mario
Published: March 2018

The current dynamics of business systems require new ways of conceiving the role of single entities. On this basis, a complex of interactions between the company and the reference context must be activated to guarantee survival dynamics. From these considerations re-emerge the ideas of Peccei (2013) and King (2013) that recognise in the systemic thought the foundations for a sustainable society. The present study derives from these considerations, and aims at contributing to the advancement of the knowledge necessary to overcome the challenges in the sustainability field. The methodological approach, albeit heuristic, can be traced back to the positive scientific and constructivist method. The results of the study showed the prevalence of qualitative and subjective techniques, accompanied by the so-called inductive method, testifying to the intense interaction between the scholar and the object investigated. With regard to future research, it would be interesting to construct a flexible, scalable and extensible model to recover both a database and an ontology for the theoretical framework.
A Novel Integrated Approach for Green Supplier Selection with Interval-Valued Intuitionistic Uncertain Linguistic Information: A Case Study in the Agri-Food Industry
Authors: Shi Hua , Quan Mei-Yun , Liu Hu-Chen , Duan Chun-Yan
Published: March 2018

With strengthening global consciousness of environmental protection, green supply chain management plays an increasingly important role in modern enterprise production operation management. A critical means to implement green supply chain management is incorporating environmental requirements into the supplier selection practices. In this paper, we put forward a novel integrated approach by using interval-valued intuitionistic uncertain linguistic sets (IVIULSs) and grey relational analysis (GRA)-technique for order preference by similarity to ideal solution (TOPSIS) method for the evaluation and selection of green suppliers. First, various qualitative assessments of alternatives provided by decision makers are described by the IVIULSs. Then, the GRA-TOPSIS method is extended and employed to prioritize the alternative suppliers. The proposed model can handle the uncertainty and fuzziness of decision makers’ subjective evaluations more easily and get a more realistic and accurate ranking of green suppliers. Finally, an illustrative example in the agri-food industry is presented to verify the proposed green supplier selection model and demonstrate its practicality and effectiveness.
The Impact of the Anisotropy of the Media between Parallel Plates on the Casimir Force
Authors: Deng Gang , Pei Ling , Hu Ni , Liu Yang , Zhu Jin-Rong
Published: March 2018

Quantum fluctuations of the electromagnetic field give rise to the force between parallel plates: the Casimir force. We theoretically calculate the Casimir force between two parallel isotropic plates when the space between the plates is filled with anisotropic material. Our result shows that the Casimir force, especially in the direction of the force, can be significantly affected by the anisotropy of the intervening material. We also discuss the combined influence of dispersion and anisotropy, and analyze the impact of the external electric filed on the Casimir force by affecting the anisotropy of the intervening material by Kerr electro-optical effect.
The Merger of Two Compact Stars: A Tool for Dense Matter Nuclear Physics
Authors: Drago Alessandro , Pagliara Giuseppe , Popov Sergei , Traversi Silvia , Wiktorowicz Grzegorz
Published: March 2018

We discuss the different signals, in gravitational and electromagnetic waves, emitted during the merger of two compact stars. We will focus in particular on the possible contraints that those signals can provide on the equation of state of dense matter. Indeed, the stiffness of the equation of state and the particle composition of the merging compact stars strongly affect, e.g., the life time of the post-merger remnant and its gravitational wave signal, the emission of the short gamma-ray-burst, the amount of ejected mass and the related kilonova. The first detection of gravitational waves from the merger of two compact stars in August 2017, GW170817, and the subsequent detections of its electromagnetic counterparts, GRB170817A and AT2017gfo, is the first example of the era of “multi-messenger astronomy”: we discuss what we have learned from this detection on the equation of state of compact stars and we provide a tentative interpretation of this event, within the two families scenario, as being due to the merger of a hadronic star with a quark star.
Hadron–Quark Combustion as a Nonlinear, Dynamical System
Authors: Ouyed Amir , Ouyed Rachid , Jaikumar Prashanth
Published: March 2018

The hadron–quark combustion front is a system that couples various processes, such as chemical reactions, hydrodynamics, diffusion, and neutrino transport. Previous numerical work has shown that this system is very nonlinear, and can be very sensitive to some of these processes. In these proceedings, we contextualize the hadron–quark combustion as a nonlinear system, subject to dramatic feedback triggered by leptonic weak decays and neutrino transport.
Using Sap Flow Data to Parameterize the Feddes Water Stress Model for Norway Spruce
Authors: Rabbel Inken , Bogena Heye , Neuwirth Burkhard , Diekkrüger Bernd
Published: March 2018

Tree water use is a key variable in forest eco-hydrological studies and is often monitored by sap flow measurements. Upscaling these point measurements to the stand or catchment level, however, is still challenging. Due to the spatio-temporal heterogeneity of stand structure and soil water supply, extensive measuring campaigns are needed to determine stand water use from sap flow measurements alone. Therefore, many researchers apply water balance models to estimate stand transpiration. To account for the effects of limited soil water supply on stand transpiration, models commonly refer to plant water stress functions, which have rarely been parameterized for forest trees. The aim of this study was to parameterize the Feddes water stress model for Norway spruce (Picea abies [L.] Karst.). After successful calibration and validation of the soil hydrological model HYDRUS-1D, we combined root-zone water potential simulations with a new plant water stress factor derived from sap flow measurements at two plots of contrasting soil moisture regimes. By calibrating HYDRUS-1D against our sap flow data, we determined the critical limits of soil water supply. Drought stress reduced the transpiration activity of mature Norway spruce at root-zone pressure heads <−4100 cm, while aeration stress was not observed. Using the recalibrated Feddes parameters in HYDRUS-1D also improved our water balance simulations. We conclude that the consideration of sap flow information in soil hydrological modeling is a promising way towards more realistic water balance simulations in forest ecosystems.
Application of an Automated Discharge Imaging System and LSPIV during Typhoon Events in Taiwan
Authors: Huang Wei-Che , Young Chih-Chieh , Liu Wen-Cheng
Published: March 2018

An automated discharge imaging system (ADIS), which is a non-intrusive and safe approach, was developed for measuring river flows during flash flood events. ADIS consists of dual cameras to capture complete surface images in the near and far fields. Surface velocities are accurately measured using the Large Scale Particle Image Velocimetry (LSPIV) technique. The stream discharges are then obtained from the depth-averaged velocity (based upon an empirical velocity-index relationship) and cross-section area. The ADIS was deployed at the Yu-Feng gauging station in Shimen Reservoir upper catchment, northern Taiwan. For a rigorous validation, surface velocity measurements were conducted using ADIS/LSPIV and other instruments. In terms of the averaged surface velocity, all of the measured results were in good agreement with small differences, i.e., 0.004 to 0.39 m/s and 0.023 to 0.345 m/s when compared to those from acoustic Doppler current profiler (ADCP) and surface velocity radar (SVR), respectively. The ADIS/LSPIV was further applied to measure surface velocities and discharges during typhoon events (i.e., Chan-Hom, Soudelor, Goni, and Dujuan) in 2015. The measured water level and surface velocity both showed rapid increases due to flash floods. The estimated discharges from ADIS/LSPIV and ADCP were compared, presenting good consistency with correlation coefficient R = 0.996 and normalized root mean square error NRMSE = 7.96%. The results of sensitivity analysis indicate that the components till (τ) and roll (θ) of the camera are most sensitive parameters to affect the surface velocity using ADIS/LSPIV. Overall, the ADIS based upon LSPIV technique effectively measures surface velocities for reliable estimations of river discharges during typhoon events.
Implementing change in primary care practice: lessons from a mixed-methods evaluation of a frailty initiative
Authors: Bryce Carol , Fleming Joanna , Reeve Joanne
Published: March 2018

Background

The NHS is facing increasing needs from an aging population, which is acutely visible in the emerging problem of frailty. There is growing evidence describing new models of care for people living with frailty, but a lack of evidence on successful implementation of these complex interventions at the practice level.

Aim

This study aimed to determine what factors enable or prevent implementation of a whole-system, complex intervention for managing frailty (the PACT initiative) in the UK primary care setting.

Design & setting

A mixed-methods evaluation study undertaken within a large clinical commissioning group (CCG). Design and analysis was informed by normalisation process theory (NPT).

Method

Data collection from six sites included: observation of delivery, interviews with staff, and an online survey. NPT-informed analysis sought to identify enablers and barriers to implementation of change.

Results

Seven themes were identified. PACT was valued by professionals and patients but a lack of clarity on its aims was identified as a barrier to implementation. Successful implementation relied on champions pushing the work forward, and dealing with unanticipated resistance. Contracts focused on delivery of service outcomes, but these were sometimes at odds with professional priorities. Implementation followed evidence-informed rather than evidence-based practice, requiring redesign of the intervention and potentially created a new body of knowledge on managing frailty.

Conclusion

Successful implementation of complex interventions in primary care need inbuilt capacity for flexibility and adaptability, requiring expertise as well as evidence. Professionals need to be supported to translate innovative practice into practice-based evidence.
Featural definition of syntactic positions: Evidence from hyper-raising
Authors: Fong Suzana
Published: March 2018

Hyper-raising consists in raising a DP from an embedded finite clause into the matrix clause. HR introduces a phase problem: the embedded clause is finite, which is supposed to be impervious to raising. This can be overcome by postulating A-features at the C of the the embedded clause. They trigger the movement of the subject to [Spec, CP]. Being at the edge of a phase, it is visible to a matrix probe. If successful, this analysis provides support for the claim that syntactic positions are not inherently A or A-bar; they can be defined featurally instead.
Inherent case in Archaic Chinese
Authors: Aldridge Edith
Published: March 2018

This paper proposes an analysis of subject case in Late Archaic Chinese (LAC). By examining the distribution of first person pronominal subjects, I conclude that there were two distinct morphological cases for subjects in LAC. One of these pronouns, 我 wǒ, valued structural nominative case, while the other one, 吾 wú, was marked with a different case. The occurrence of 吾 wú as the external argument of experiencer and modal predicates clearly suggests that this case was at least sometimes inherent case assigned to the external argument in [Spec, vP]. 吾 wú also functioned as the subject of relative clauses, embedded subjunctive clauses, and irrealis matrix clauses. Since the case valued in these clause types was not sensitive to predicate types, I propose that the source of the case valued by the subject in these environments was T. Working within Chomsky’s (2008) C-T Inheritance framework, I propose that Inheritance did not take place in indicative clauses, so the subject moved to [Spec, CP] to value nominative case. A first person pronoun with nominative case was spelled out as 我 wǒ. But Inheritance was forced if another constituent needed to occupy [Spec, CP]. I propose that relative clauses and irrealis/subjunctive clauses are all derived through operator movement. Because the operator must occupy [Spec, CP], C-T Inheritance must also take place, forcing the subject to move to [Spec, TP] to value its case. The case valued in this position was also the non-nominative form exemplified by the first person pronoun 吾 wú.
A compositional approach to conjunct agreement in Turkish
Authors: Koylu Yilmaz
Published: March 2018

This article presents novel empirical evidence on verbal agreement patterns observed in conjunction phrases (CPs) in Turkish. To account for the discrepancies observed in native speaker preferences in agreement paradigms in CPs, two experimental tasks were carried out: namely an acceptability judgment task and a forced choice task. Based on the results, it is proposed that there is compositional conjunct agreement in Turkish that takes place in two stages. The agreement relationship is first established between the Agreement head and the coordinated phrase in the syntax. Then, the PF spells out the features of either the coordinated phrase, or the features of the linearly closest conjunct inside the coordinated phrase. I argue that Full Agreement (FA) results from the Spec-head agreement with the CP, whereby the features of both conjuncts are resolved and inherited to the CP (Johannessen 1996). In Closest Conjunct Agreement (CCA), on the other hand, the agreeing head has asymmetric access to one of the prominent conjuncts or its features (Bošković 2009; Johannessen 1998; Munn 1993, 1999; Benmamoun 1992). Thus, in CCA in Turkish, the agreement is with the linearly closest conjunct and the features of that conjunct appear on the verb.
Linguistics and race: An interdisciplinary approach towards an LSA statement on race
Authors: Charity Hudley Anne H. , Mallinson Christine , Bucholtz Mary , Flores Nelson , Holliday Nicole , Chun Elaine , Spears Arthur
Published: March 2018

In order to work towards greater racial justice within linguistics, the challenge remains for linguists to develop a cohesive theory of and approach to race and racial analysis in linguistics that is influenced by researchers of different methodological approaches and racial backgrounds. A formal LSA statement on race will provide linguistic researchers with a framework for studying race and will also serve as a method of intellectual and social inclusion in linguistics. We draw on interdisciplinary expertise in related fields, including psychology, sociology, anthropology, education, and ethnic studies, to examine how scholars from >neighboring disciplines have formally conceptualized and dealt with race and racial classification strategies. Points of convergence as well as divergence are articulated, drawing insights that may advance work related to race within and beyond linguistics.
Against the universal phasehood of nP: Evidence from the morphosyntax of book titles
Authors: Erschler David
Published: March 2018

Languages vary as to whether DPs used as book titles (such as Alice in Wonderland, Harry Potter and the Philosopher’s Stone, etc.) can be assigned case and trigger agreement. In languages where they do participate in case and agreement relations, book (and movie) titles form a subsystem with very peculiar properties. I argue that when used as a title, any XP gets embedded in a new nP which projects a DP. Phasehood properties of nPs vary across languages, which leads to the variation in the agreement properties of book titles. However, even in languages that normally require lexical DP titles to trigger agreement and be assigned case, personal pronouns and other functional are exempt from this. I argue that this is related to the fact that participation in case assignment and agreement makes the index and the phi-features of a pronoun visible on the LF thus creating an interpretational conflict.
Sonority bias in Rugao di-syllabic syllable contraction
Authors: Xu Chenchen , Lin Yen-Hwei , Durvasula Karthik
Published: March 2018

Two analyses, vowel sonority and the linear order of pre-contraction vowels, have been proposed to account for the vowel selection between two competing vowels in Chinese syllable contraction. An experiment was run to test whether sonority and/or linear order bias the vowel selection in Rugao syllable contraction. Our results confirmed the role of vowel sonority, and did not present supporting evidence for the linear order analysis. Sonority hierarchies along the dimensions of both height and centrality exhibit the same consistent and robust pattern, providing a new perspective to look at competing vowels in vowel-related phonological processes.
Covert reflexive argument in inalienable relational nouns
Authors: Ke Alan Hezao , Pires Acrisio
Published: March 2018

This paper argues that inalienable relational nouns in Mandarin Chinese, specifically kinship nouns (e.g. father, sister) and body-part nouns (e.g. head, face), have an implicit reflexive argument. Based on  a syntactic comparison between kinship nouns, body-part nouns, local- and long-distance bound reflexives, we argue that the implicit reflexive arguments of kinship nouns and body-part nouns differ from each other: The implicit argument of kinship nouns must be locally bound, whereas that of body-part nouns can either be locally bound or long-distance bound. Therefore, we conclude that these two types of implicit arguments in Mandarin Chinese correspond to local- long-distance bound reflexives, respectively. Finally, we relate this difference to binding theory concerning local and long-distance anaphors.
Suffix interference in Russian
Authors: Comstock Lindy B
Published: March 2018

The phenomenon of “suffix interference” has been used as evidence for a distinction between inflectional and derivational processes (e.g. Pinker & Prince, 1988; Pinker, 1999; Pinker & Ullman, 2002). Yet much of the work on affix priming exists in English, a morphologically poor language, and suffix interference appears inconsistently in cross-linguistic data. The greater reliance on morphological complexity in Russian, and its use of an infinitival suffix and aspectual affixes that may bridge the distinction between traditional definitions of inflectional and derivational word forms, call into question how generalizable the original findings on suffix interference may be for morphologically-complex languages. Investigating these questions, this paper provides unexpected findings: suffix interference is absent in Russian, inflectional suffixes reveal significantly more robust priming effects, and the infinitival suffix is best considered a special case of affix priming, failing to pattern with either inflectional or derivational suffixes. Thus, Russian appears to defy the assumption that inflections are “stripped” during morphological parsing; instead, verbal inflections prove the greatest facilitators of morphological priming. A linear mixed effects model indicates these effects cannot be explained by frequency alone.
On the Foundation of Equipartition in Supernova Remnants
Authors: Urošević Dejan , Pavlović Marko Z. , Arbutina Bojan
Published: March 2018

A widely accepted paradigm is that equipartition (eqp) between the energy density of cosmic rays (CRs) and the energy density of the magnetic field cannot be sustained in supernova remnants (SNRs). However, our 3D hydrodynamic supercomputer simulations, coupled with a nonlinear diffusive shock acceleration model, provide evidence that eqp may be established at the end of the Sedov phase of evolution in which most SNRs spend the longest portions of their lives. We introduce the term “constant partition” for any constant ratio between the CR energy density and the energy density of the magnetic field in an SNR, while the term “equipartition” should be reserved for the case of approximately the same values of the energy density (also, it is constant partition in the order of magnitude) of ultra-relativistic electrons only (or CRs in total) and the energy density of the magnetic field. Our simulations suggest that this approximate constant partition exists in all but the youngest SNRs. We speculate that since evolved SNRs at the end of the Sedov phase of evolution can reach eqp between CRs and magnetic fields, they may be responsible for initializing this type of eqp in the interstellar medium. Additionally, we show that eqp between the electron component of CRs and the magnetic field may be used for calculating the magnetic field strength directly from observations of synchrotron emission from SNRs. The values of magnetic field strengths in SNRs given here are approximately 2.5 times lower than values calculated by Arbutina et al.

Impulsively generated sausage wave trains in coronal structures are important for interpreting a substantial number of observations of quasi-periodic signals with quasi-periods of order seconds. We have previously shown that the Morlet spectra of these wave trains in coronal tubes depend crucially on the dispersive properties of trapped sausage waves, the existence of cutoff axial wavenumbers, and the monotonicity of the dependence of the axial group speed on the axial wavenumber in particular. This study examines the difference a slab geometry may introduce, for which purpose we conduct a comprehensive eigenmode analysis, both analytically and numerically, on trapped sausage modes in coronal slabs with a considerable number of density profiles. For the profile descriptions examined, coronal slabs can trap sausage waves with longer axial wavelengths, and the group speed approaches the internal Alfvén speed more rapidly at large wavenumbers in the cylindrical case. However, common to both geometries, cutoff wavenumbers exist only when the density profile falls sufficiently rapidly at distances far from coronal structures. Likewise, the monotonicity of the group speed curves depends critically on the profile steepness right at the structure axis. Furthermore, the Morlet spectra of the wave trains are shaped by the group speed curves for coronal slabs and tubes alike. Consequently, we conclude that these spectra have the potential for inferring the subresolution density structuring inside coronal structures, although their detection requires an instrumental cadence of better than ∼1 s.

It has been proposed that some meteorites, CB and CH chondrites, contain material formed as a result of a protoplanetary collision during accretion. Their melt droplets (chondrules) and FeNi metal are proposed to have formed by evaporation and condensation in the resulting impact plume. We observe that the skeletal olivine (SO) chondrules in CBb chondrites have a blebby texture and an enrichment in refractory elements not found in normal chondrules. Because the texture requires complete melting, their maximum liquidus temperature of 1928 K represents a minimum temperature for the putative plume. Dynamic crystallization experiments show that the SO texture can be created only by brief reheating episodes during crystallization, giving a partial dissolution of olivine. The ejecta plume formed in a smoothed particle hydrodynamics simulation served as the basis for 3D modeling with the adaptive mesh refinement code FLASH4.3. Tracer particles that move with the fluid cells are used to measure the in situ cooling rates. Their cooling rates are ∼10,000 K hr−1 briefly at peak temperature and, in the densest regions of the plume, ∼100 K hr−1 for 1400–1600 K. A small fraction of cells is seen to be heating at any one time, with heating spikes explained by the compression of parcels of gas in a heterogeneous patchy plume. These temperature fluctuations are comparable to those required in crystallization experiments. For the first time, we find an agreement between experiments and models that supports the plume model specifically for the formation of CBb chondrules.
Distribution, diversity patterns and faunogenesis of the millipedes (Diplopoda) of the Himalayas
Authors: Golovatch Sergei I. , Martens Jochen
Published: March 2018

The Himalayas support a highly rich, diverse, multi-layered, mostly endemic diplopod fauna which presently contains >270 species, 53 genera, 23 families and 13 orders. This is the result of mixing the ancient, apparently Tertiary and younger, Plio-Pleistocene elements of various origins, as well as the most recent anthropochore (= man-mediated) introductions. At the species and, partly, generic levels, the fauna is largely autochthonous and sylvicolous, formed through aboundingin situradiation and vicariance events. In general, the species from large genera and families tend to occupy a wide range of altitudes, but nearly each of the constituent species shows a distribution highly localized both horizontally and altitudinally, yet quite often with sympatry or even syntopy involved. The bulk of the fauna is Indo-Malayan in origin, with individual genera or families shared with those of SE Asia (mostly) and/or S India (few). Sino-Himalayan and, especially, Palaearctic components are subordinate, but also clearly distinguishable.

The total species richness in the myriapod assemblages of the lowland Altais near Charyshskoe Village, Altai Province, southwestern Siberia, Russia is estimated to be at least 19 species from ten genera, eight families, five orders, and two classes. The following species are new to SW Siberia: Lithobius (Ezembius) ostiacorum Stuxberg, 1876,L. vagabundusStuxberg, 1876, and L. (Monotarsobius) nordenskioeldii Stuxberg, 1876, while L. (E.) proximus Sseliwanoff, 1880 and L. (M.) insolens Dányi & Tuf, 2012 are recorded for the first time from the Altai Province of Russia. A species ofStrigamiawhich is morphologically similar to Strigamia cf. transsilvanica (Verhoeff, 1928) has been found in the study area but its true specific identity is yet to be determined. The seasonal dynamics of myriapod assemblages in terms of the species diversity, density, sex-age structure, and vertical distribution along the soil profile have been studied with regard to the different slope exposures.
VIRMISCO – The Virtual Microscope Slide Collection

Digitisation allows scientists rapid access to research objects. For transparent to semi-transparent three-dimensional microscopic objects, such as microinvertebrates or small body parts of organisms, available databases are scarce. Most mounting media used for permanent microscope slides deteriorate after some years or decades, eventually leading to total damage and loss of the object. However, restoration is labour-intensive, and often the composition of the mounting media is not known. A digital preservation of important material, especially types, is important and an urgent need. The Virtual Microscope Slide Collection – VIRMISCO project has developed recommendations for taking microscopic image stacks of three-dimensional objects, depositing and presenting such series of digital image files or z-stacks as an online platform. The core of VIRMISCO is an online viewer, which enables the user to virtually focus through an object online as if using a real microscope. Additionally, VIRMISCO offers features such as search, rotating, zooming, measuring, changing brightness or contrast, taking snapshots, leaving feedback as well as downloading complete z-stacks as jpeg files or video file. The open source system can be installed by any institution and can be linked to common database or images can be sent to the Senckenberg Museum of Natural History Görlitz. The benefits of VIRMISCO are the preservation of important or fragile material, to avoid loan, to act as a digital archive for image files and to allow determination by experts from the distance, as well as providing reference libraries for taxonomic research or education and providing image series as online supplementary material for publications or digital vouchers of specimens of molecular investigations are relevant applications for VIRMISCO.
Un exemple de circuit court dans l’aide alimentaire : de A2MAP à Uniterres-équitable
Authors: Blanchot Véronique , Téchoueyres Isabelle
Published: March 2018

Cet article est un témoignage de terrain dans le champ de l’aide alimentaire et tout particulièrement celui des épiceries sociales. Il présente la mise en place, par l’une des auteures, d’un dispositif d’approvisionnement local en circuit court : Uniterres. Face au manque de fruits et légumes frais dans les épiceries sociales, et au constat que de plus en plus d’agriculteurs s’inscrivent comme bénéficiaires de ces structures, Uniterres propose de reconnecter agriculture et aide alimentaire tout en soutenant une agriculture paysanne de proximité. A travers les différentes étapes du développement de ce projet, cet article expose les problématiques rencontrées sur le terrain et les adaptations qui ont été nécessaires. A travers cet article sont abordées les thématiques actuelles touchant à la mise en place d’une démocratie alimentaire, mais aussi les difficultés rencontrées dans un contexte d’économie de marché.
La recherche en GRH entre rigueur et pertinence : apport de la contextualisation
Authors: Igalens Jacques , Tahri Najoua
Published: March 2018

Le débat traditionnel concernant l’arbitrage auquel est confrontée la recherche en management entre pertinence et rigueur n’épargne pas la GRH. L’ouvrage de Gibbons en a toutefois renouvelé les termes en décrivant deux régimes de production des savoirs (M1K et M2K) qui permettent de mieux cerner les caractéristiques principales de ce que certains appellent également la « science académique » versus la « science post académique ». Nous examinons, pour la GRH, chacune des caractéristiques de ces deux régimes (notamment en analysant les 106 articles du précédent congrès de l’AGRH à Montpellier) avant de proposer un pont entre les deux, la contextualisation.
Peut-on compenser des conditions de travail nocives ? L’apport du modèle Exigences-Ressources
Authors: Silveri Federica
Published: March 2018

Cet article porte sur les ressources qui ont le potentiel de réduire les effets des conditions de travail nocives. Nous avons effectué une revue systématique des applications du modèle Exigences/Ressources. La revue nous a permis d’identifier les ressources citées dans la littérature. Nous avons classé ces ressources dans une grille de codage, utile pour de futurs travaux. Au-delà de la contribution à la théorie Exigences/Ressources, nos travaux souhaitent aussi contribuer à la prise de conscience, par les managers, de l’intérêt de certaines ressources pour la mise en place de meilleures conditions de travail.
Équilibre vie personnelle-vie professionnelle, Soutien social, Engagement et Satisfaction au travail : une analyse des effets médiateurs
Authors: Kilic Sinem
Published: March 2018

Peu de recherches analysent les effets de médiation qui peuvent exister entre l’engagement dans le travail, le soutien social perçu, l’équilibre vie personnelle-vie professionnelle et la satisfaction au travail. Cette étude, conduite auprès de 224 cadres du secteur privé, montre que la perception de l’équilibre de vie est un médiateur sur deux niveaux. Premièrement, sur la relation entre le soutien social perçu et la satisfaction au travail, mais c’est plus spécifiquement le soutien du manager à la fois pour des questions liées au travail et au hors-travail qui contribue le plus à cet effet. Cela interroge sur l’évolution du rôle et des compétences du manager qui se voit de plus en plus gérer les frontières entre travail et hors-travail de ses collaborateurs. Deuxièmement, sur la relation entre engagement dans le travail et satisfaction au travail, ce qui traduit l’évolution des attentes des salariés vers plus de qualité de vie au travail.
