Published: October 2021

AbstractCalcination treatments in the range of 500–900 °C of TiO2 synthesised by the sol–gel resulted in materials with variable physicochemical (i.e., optical, specific surface area, crystallite size and crystalline phase) and morphological properties. The photocatalytic performance of the prepared materials was evaluated in the oxygen evolution reaction (OER) following UV-LED irradiation of aqueous solutions containing iron ions as sacrificial electron acceptors. The highest activity for water oxidation was obtained with the photocatalyst thermally treated at 700 °C (TiO2-700). Photocatalysts with larger anatase to rutile ratio of the crystalline phases and higher surface density of oxygen vacancies (defects) displayed the best performance in OER. The oxygen defects at the photocatalyst surface have proven to be responsible for the enhanced photoactivity, acting as important active adsorption sites for water oxidation. Seeking technological application, water oxidation was accomplished by immobilising the photocatalyst with the highest OER rate measured under the established batch conditions (TiO2-700). Experiments operating under continuous mode revealed a remarkable efficiency for oxygen production, exceeding 12% of the apparent quantum efficiency (AQE) at 384 nm (UV-LED system) compared to the batch operation mode.

Published: October 2021

Purpose:Hypernasality and atypical voice characteristics are common features of dysarthric speech due to amyotrophic lateral sclerosis (ALS). Existing acoustic measures have been developed to primarily target either hypernasality or voice impairment, and the effects of co-occurring hypernasality-voice problems on these measures are unknown. This report explores (a) the extent to which acoustic measures are affected by concurrent perceptually identified hypernasality and voice impairment due to ALS and (b) candidate acoustic measures of early indicators of hypernasality and voice impairment in the presence of multisystem involvement in individuals with ALS.Method:Two expert listeners rated severity of hypernasality and voice impairment in sentences produced by individuals with ALS (n= 27). The samples were stratified based on perceptual ratings: voice/hypernasality asymptomatic, predominantly hypernasal, predominantly voice impairment, and mixed (co-occurring hypernasality and voice impairment). Groups were compared using established acoustic measures of hypernasality (one-third octave analysis) and voice (cepstral/spectral analysis) impairment.Results:The one-third octave analysis differentiated all groups; the cepstral peak prominence differentiated all groups except asymptomatic versus mixed, whereas the low-to-high spectral ratio did not differ among groups. Additionally, one-third octave analyses demonstrated promising speech diagnostic potential.Conclusions:The results highlight the need to consider the validity of measures in the context of multisubsystem involvement. Our preliminary findings further suggest that the one-third octave analysis may be an optimal approach to quantify hypernasality and voice abnormalities in the presence of multisystem speech impairment. Future evaluation of the diagnostic accuracy of the one-third octave analysis is warranted.
Response reliability and risk analysis of users under time‐of‐use price

Published: October 2021

AbstractTime‐of‐use (TOU) electricity prices are implemented based on the response characteristics of users. TOU prices guide the electricity consumption behaviour of users and make them actively respond to peak shaving and valley filling. In this paper, the conventional psychology response model of consumers is improved based on the history data of customer response to the TOU price. The paper defines four types of response load curves and proposes the response reliability indices. Additionally, it establishes the probability models of customer response. According to the characteristics of customer response, the sensitivity analysis of influencing factors and the risk analysis of customers are carried out according to the probability model of response. For instance, risk and characteristics analyses of the customer response were performed using the load data of residential areas in Nanjing city. The results indicate that the probability distribution of the customer response is approximate to the trapezoid distribution. The sequence of sensitivity coefficients of customer response factors is as follows: customer income, type of customer, and electrical equipment. The proposed method provides a scientific basis for electricity price implementers to accurately grasp the response behaviour of the user and establish a reasonable demand response strategy.
Distributionally robust co‐optimization of the demand‐side resources and soft open points allocation for the high penetration of renewable energy

Published: October 2021

AbstractThe new technologies, such as soft open points (SOPs) and demand response (DR), offer original approaches to stabilize the system operation and accommodate the high penetration of distributed generators (DGs). However, the applied effects of these technologies are closely affected by the uncertainties of the consumer's willingness and the outputs of DGs. To solve the problems caused by the uncertainty of the resources in active distribution system, this paper proposes a distributionally robust co‐optimization model for the demand side resources and SOPs, which realizes the combination of investment economy and operation robustness. Next, using equivalent substitution and polyhedron linearization technique, this paper proposes the mathematical method which transforms the original non‐linear programming model into a mixed‐integer linear programming model, and obtains the solution to the distributionally robust model with column and constraint generation (CCG) algorithm. Finally, the effectiveness of the proposed model is verified with the sample from a power distribution system in northern China. The result demonstrates that the co‐optimization model can realize complementary advantages of the demand side resources and SOPs, which can not only guarantee the economy of scheme, but also improve the accommodation of DGs.

Published: October 2021

AbstractThis paper proposes a power system multimode generator energy loss factor (GELF) based on energy flow method under environmental excitation. This index can evaluate generator damping changes in different oscillation modes in power systems, timely discover the damping deterioration of the generator, and track the source of low‐frequency oscillation. A signal expression method for electrical frequency domain under environmental excitation is derived. This method is combined with dissipated energy flow method to obtain a new type of GELF. In terms of signal processing, dynamic mode decomposition and Morlet wavelet filter extraction system mode components are used to improve computing accuracy. The proposed index enables online calculation with the support of phasor measurement unit and wide area measurement system. Simulation analysis is conducted in a standard 39 node system and wind‐integrated power system. Test results show the effectiveness and generality of the proposed index and method.
Management komplexer Behandlungsbedarfe durch Patientenlotsen – eine qualitative Studie zur Erfassung des Status quo in der GKV
Authors: Brandt Florian , Salm Frederike 
Published: October 2021

Zusammenfassung
Zielsetzung Seit mehreren Jahren werden Lotsenansätze zur patientenorientierten Versorgungskoordination in unterschiedlichen Modellprojekten erprobt. Diese Studie soll beantworten, welche projektübergreifenden Erkenntnisse hinsichtlich Zugangsvoraussetzungen, organisatorischer Rahmenbedingungen und Zielgruppen gewonnen werden konnten und welche Implikationen sich hieraus für den Transfer in die bundesweite Regelversorgung ergeben.
Methodik Die erforderlichen Daten wurden in einem qualitativ-explorativen Forschungsdesign erhoben. Es wurden leitfadengestützte Interviews mit 14 einschlägigen Experten geführt, aufgezeichnet, transkribiert und mittels qualitativer Inhaltsanalyse ausgewertet.
Ergebnisse Haupteinsatzgebiet laut den Experten sind komplexe Behandlungssettings sowie Patientengruppen mit besonderem Unterstützungsbedarf. Neben einer Ausbildung und Berufserfahrung im Bereich der Humandienstleistungen, ist eine sozialrechtliche Schulung als Zugangsvoraussetzung sinnvoll. Auch eine klare Definition und Abgrenzung des Tätigkeitsprofils sowie eine Verzahnung mit der ambulanten und stationären Versorgung wurden mehrfach als hilfreich genannt. Die Experten waren sich weitestgehend darüber einig, dass Patientenlotsen strukturell in der GKV angesiedelt werden sollten. Eine Finanzierungsbeteiligung anderer Sozialversicherungssysteme sei aufgrund inhaltlicher Überschneidungen jedoch angemessen.
Schlussfolgerung Patientenlotsen unterstützen bedürftige Patienten bei der Koordination komplexer Versorgungsbedarfe und leisten damit einen Beitrag zur Verbesserung von Effektivität und Effizienz der Gesundheitsversorgung. Nachdem eine Vielzahl von praktischen Erkenntnissen zum Einsatz von Patientenlotsen in entsprechenden Modellprojekten gewonnen werden konnte, erscheint eine Übertragung in die bundesweite Regelversorgung nun geboten.

Published: October 2021

Abstract
Daphniphyllum alkaloids have complex molecular structures; consequently, their synthesis can be challenging. A new method for the construction of the [7-5-5] tricyclic core of Daphniphyllum alkaloids was developed. The bicyclo[5.3.0]decane skeleton was constructed through a divinylcyclopropane rearrangement of a cyclopentenone derivative with a vinylcyclopropyl group at the β-position. After introduction of a 2-iodoethyl group by a regioselective Michael addition with phenyl vinyl selenone, the [7-5-5] tricyclic system was formed by intramolecular alkylation of a cyclopentadienyl anion species.
Partial Regression of Congenital Brain Stem Glioma and Its Outcome
Authors: Kadam Sandeep , Chavan Rajendra , Kadam Archana , Patole Sanjay 
Published: October 2021

AbstractCongenital brain stem gliomas are rare in neonates and are difficult to diagnose given their subtle clinical presentation. They are usually associated with poor prognosis by their location and behavior. However, there are few reports of spontaneous regression of brain stem glioma with favorable long-term outcome. In this article, we reported a case of congenital brain stem glioma with a normal long-term outcome where a wait and watch approach allowed observation of spontaneous partial regression of the tumor with normal neurodevelopmental outcome at 40 months of age. The optimal approach to the management of children with brain stem glioma is difficult to define as, in general, the prognosis is considered poor. Selecting an “early intervention” or “wait and watch” approach depends on the nature, size, and progression of the lesion, and the risk versus benefits of early intervention. The clinical course of our case suggests that a conservative approach may be justified in selected cases as long as the parents have been counselled and regular frequent follow-up is assured.
The discourse structure of free indirect discourse reports
Authors: Bimpikou Sofia , Maier Emar , Hendriks Petra 
Published: October 2021

Abstract
We investigate the discourse structure of Free Indirect Discourse passages in narratives. We argue that Free
Indirect Discourse reports consist of two separate propositional discourse units: an (explicit or implicit) frame segment and a
reported content. These segments are connected at the level of discourse structure by a non-veridical, subordinating discourse
relation of Attribution, familiar from recent SDRT analyses of indirect discourse constructions in natural conversation (Hunter, 2016). We conducted an experiment to detect the covert presence of a
subordinating frame segment based on its effects on pronoun resolution. We compared (unframed) Free Indirect Discourse with
overtly framed Indirect Discourse and a non-reportative segment. We found that the first two indeed pattern alike in terms of
pronoun resolution, which we take as evidence against the pragmatic context split approach of Schlenker (2004) and Eckardt (2014), and in favor of our discourse
structural Attribution analysis.
Strange nominative case in topicalized object pronominal relative clauses
Authors: Suijkerbuijk Michelle , Redl Theresa , de Hoop Helen 
Published: October 2021

Abstract
In an online production experiment, we investigated the effect of sentence position on the preference for either a
nominative or object form of an object pronoun restricted by a relative clause in Dutch. Results show a significant preference for
the nominative form of the restricted object pronoun in sentence-initial position as it was chosen in 95% of the cases. In the
original object position this percentage is only 20%. The preference for a nominative pronominal object is considered a
grammatical norm violation. We account for this in terms of a combination of two factors. First, the presence of the relative
clause makes the object ‘long’. Second, the sentence-initial position is a syntactic position that is relatively far removed from
the original object position. We argue that when a long object is topicalized, there are too many intervening elements between the
pronoun and the verb of which it is the complement. If the distance between the pronominal object and the verb has become too
long, the object case fades from the working memory. This then results in the appearance of nominative case as the default case
for topicalized object pronominal relative clauses in Dutch.
“Boom! You bought them.”

Abstract
A review of advertisement studies shows that there has been little attempt to examine infomercials in terms of
rhetorical appeals and persuasive strategies. Therefore, this study sought to contribute to the existing literature by exploring
the persuasive elements of Apple infomercials through Aristotle’s modes of persuasion to reveal the most frequent persuasive
language features and structures and to study how such elements were utilized to promote the products and services of the company.
A top-down approach based on Aristotle’s modes of persuasion was adopted to identify the rhetorical appeals of logos,
ethos and pathos as well as the promotional tokens and patterns in the text. The descriptive
findings provided evidence to demonstrate that although all the rhetorical proofs were employed in the corpus, emotional appeal
was the most dominant. The findings of this research open new horizons for further studies on infomercials in general and
persuasive rhetoric in specific.
Quantitative signal subspace imaging
Authors: González-Rodríguez Pedro , Kim Arnold D , Tsogka Chrysoula 
Published: October 2021

Abstract
We develop and analyze a quantitative signal subspace imaging method for single-frequency array imaging. This method is an extension to multiple signal classification which uses (i) the noise subspace to determine the location and support of targets, and (ii) the signal subspace to recover quantitative information about the targets. For point targets, we are able to recover the complex reflectivity and for an extended target under the Born approximation, we are able to recover a scalar quantity that is related to the product of the volume and relative dielectric permittivity of the target. Our resolution analysis for a point target demonstrates this method is capable of achieving exact recovery of the complex reflectivity at subwavelength resolution. Additionally, this resolution analysis shows that noise in the data effectively acts as a regularization to the imaging functional resulting in a method that is surprisingly more robust and effective with noise than without noise.
Origin of phonon-limited mobility in two-dimensional metal dichalcogenides
Authors: Chang Hao , Wang Hao , Song Ke-Ke , Zhong Min , Shi Li-Bin , Qian Ping 
Published: October 2021

Abstract
Metal dichalcogenides are novel two-dimensional (2D) semiconductors after the discovery of graphene. In this article, phonon-limited mobility for six kinds of 2D semiconductors with the composition of MX2 is reviewed, in which M (Cr, Mo and W) is the transition metal, and X (S and Se) is the chalcogen element. The review is divided into three parts. In the first part, we briefly introduce the calculation method of mobility, including the empirical model and Boltzmann transport theory (BTE). The application scope, merits and limitations of these methods are summarized. In the second part, we explore empirical models to calculate the mobility of MX2, including longitudinal acoustic phonon, optical phonon (OP) and polar optical phonon (POP) models. The contribution of multi-valley to mobility is reviewed in the calculation. The differences between static and high-frequency dielectric constants (Δϵ) are only 0.13 and 0.03 for MoS2 and WS2. Such a low value indicates that the polarization hardly changes in the external field. So, their mobility is not determined by POP, but by deformation potential models. Different from GaAs, POP scattering plays a decisive role in its mobility. Our investigations also reveal that the scattering from POP cannot be ignored in CrSe2, MoSe2 and WSe2. In the third parts, we investigate the mobility of MX2 using electron–phonon coupling matrix element, which is based on BTE from the framework of a many-body quantum-field theory. Valence band splitting of MoS2 and WS2 is induced by spin–orbit coupling effect, which leads to the increase of hole mobility. In particular, we review in detail the theoretical and experimental results of MoS2 mobility in recent ten years, and its mobility is also compared with other materials to deepen the understanding.
FFT based approaches in micromechanics: fundamentals, methods and applications
Authors: Lucarini S , Upadhyay M V , Segurado J 
Published: October 2021

Abstract
FFT methods have become a fundamental tool in computational micromechanics since they were first proposed in 1994 by Moulinec and Suquet for the homogenization of composites. Since then many different approaches have been proposed for a more accurate and efficient resolution of the non-linear homogenization problem. Furthermore, the method has been pushed beyond its original purpose and has been adapted to a variety of problems including conventional and strain gradient plasticity, continuum and discrete dislocation dynamics, multi-scale modeling or homogenization of coupled problems such as fracture or multi-physics problems. In this paper, a comprehensive review of FFT approaches for micromechanical simulations will be made, covering the basic mathematical aspects and a complete description of a selection of approaches which includes the original basic scheme, polarization based methods, Krylov approaches, Fourier–Galerkin and displacement-based methods. Then, one or more examples of the applications of the FFT method in homogenization of composites, polycrystals or porous materials including the simulation of damage and fracture will be presented. The applications will also provide an insight into the versatility of the method through the presentation of existing synergies with experiments or its extension toward dislocation dynamics, multi-physics and multi-scale problems. Finally, the paper will analyze the current limitations of the method and try to analyze the future of the application of FFT approaches in micromechanics.
Modeling and experimental validation of thin, tightly rolled dielectric elastomer actuators

Published: October 2021

Abstract
Due to their large deformation, high energy density, and high compliance, dielectric elastomer actuators (DEAs) have found a number of applications in several areas of mechatronics and robotics. Among the many types of DEAs proposed in the literature, rolled DEAs (RDEAs) represent one of the most popular configurations. RDEAs can be effectively used as compact muscle-like actuators for soft robots, since they allow eliminating the need for external motors or compressors while providing at the same time a flexible and lightweight structure with self-sensing capabilities. To effectively design and control complex RDEA-driven systems and robots, accurate and numerically efficient mathematical models need to be developed. In this work, we propose a novel lumped-parameter model for silicone-based, thin and tightly rolled RDEAs. The model is grounded on a free-energy approach, and permits to describe the electro-mechanically coupled response of the transducer with a set of nonlinear ordinary differential equations. After deriving the constitutive relationships, the model is validated by means of an extensive experimental campaign, conducted on three RDEA specimens having different geometries. It is shown how the developed model permits to accurately predict the effects of several parameters (external load, applied voltage, actuator geometry) on the RDEA electro-mechanical response, while maintaining an overall simple mathematical structure.
