AbstractConventional chemical doping processes for conjugated polymers (CPs) often degrade the film morphology or cause unsatisfactory doping efficiency owing to the aggregation formation between charged species or insufficient dopant diffusion. In this work, a new strategic doping method, “hybrid doping,” is suggested for maximizing the doping efficiency of CPs without hampering the surface morphology of the CP films. The advantage of hybrid doping is that it combines mixture blending and sequential soaking processes. Based on systemic characterizations including spectroscopic, structural, and electrical analyses, it is revealed that hybrid doping enables whole area doping for the crystalline and amorphous regions of CP films, and thus an unprecedentedly high electrical conductivity of up to 81.5 and 639.1 S cm−1, for poly(3‐hexylthiophene) P3HT and poly (2‐([2,2′‐bithiophen]‐5‐yl)‐3,8‐difluoro‐5,10‐bis(5‐octylpentadecyl)‐5,10‐dihydroindolo [3,2‐b]indole) (PIDF‐BT), respectively, is achieved. Furthermore, the exceptional electrical conductivity compensates a reduced Seebeck coefficient, resulting in excellent power factors up to 26.8 and 76.1 μW m−1 K−2 for thermoelectric devices based on doped‐P3HT and PIDF‐BT films, respectively, which is among the highest levels for semiconducting CPs. Hybrid doping is a strategic approach for the simultaneous optimization of electrical conductivity and thermoelectric properties of various CPs.

Published: August 2020

SummaryThe evolution of the traditional power system toward the modern smart grid has posed many new cybersecurity challenges to this critical infrastructure. One of the most dangerous cybersecurity threats is the false data injection (FDI) attack, especially when it is capable of completely bypassing the widely deployed bad data detector of state estimation (SE) and interrupting the normal operation of the power system. Most of the simulated FDI attacks are designed using a simplified linearized DC model, while most of the industry‐standard SE systems are based on the nonlinear AC model. In this article, a comprehensive FDI attack scheme is presented based on the nonlinear AC model. A case study of the nine‐bus Western System Coordinated Council (WSCC)'s power system is provided, using an industry‐standard package to assess the outcomes of the proposed design scheme. A public FDI dataset is generated as a test set for the community to develop and evaluate new detection algorithms, which are lacking in the field. The FDI's stealthy quality of the dataset is assessed and proven through a preliminary analysis based on both physical power law and statistical analysis.

Abstract
In the past decade, clinical and laboratory studies have led to important new insights into the biology of leukemia and its treatment. This review describes the progress of leukemia research in the United States in recent years. Whereas the traditional method of treatment is chemotherapy, it is nonselective and could induce systemic toxicities. Thus, in parallel with research on new chemotherapies, great emphasis has been placed on developing immunotherapies. Here, we will review the current immunotherapies available in research and development that overcome current challenges, specifically looking in the field of chimeric antigen receptor T-cell (CAR-T) therapies, checkpoint inhibitors, and antibody-drug conjugates. With about 100 clinical trials for CAR-T therapies and 30 in checkpoint inhibitors for leukemia treatment, scientists are trying to make these technologies cheaper, faster, and more feasible. Further describing the delivery of these therapeutics, we look at the current progress, clinical, and preclinical status of nano-based medicines such as liposomes, polymeric micelles, and metal nanoparticles. Taking advantage of their physicochemical and biologic properties, nanoparticles have been shown to increase the efficacy of commonly administered chemotherapies with reduced adverse effects.

Published: August 2020

AbstractChild refugees are at high risk for problems with academic achievement and psychosocial well‐being. We aimed to review the literature concerning these outcomes in primary school–aged child refugees. This study was a systematic review and included studies that reported on outcomes of interest in child refugees between 5 and 12 years of age. Our search generated 3,172 articles; we selected 313 for review and included 45. Child refugees are diverse in their educational performance, and early deficits often resolve with time spent in the host country. These children are at an increased risk of emotional and behavioral difficulties, and multiple factors are associated with these outcomes. Although educational difficulties of primary school–aged child refugees in high‐income countries tend to resolve, the risks for psychosocial problems persist. This review provides a deepened understanding of the diverse educational and psychosocial experiences of these children and highlights the need for developing health and educational programs to support this population.

Published: August 2020

ObjectivesPhysician compensation for procedures is typically rooted in the work relative value unit (wRVU) system. Operative time is one of the factors that goes into the determination of wRVU assignment. There should be consistency between the wRVU/hr rate, irrespective of average operative time required to perform certain procedures. We investigate if wRVU assignment for otolaryngology procedures adequately accounts for increased operative time.Study DesignRetrospective analysis of a surgical database.MethodsNSQIP was queried from 2015–2018 for the top 50 most frequently performed otolaryngology Current Procedural Terminology (CPT) codes completed as standalone procedures. Median operative time was determined for each CPT code, and wRVU/hr was calculated. Correlations between operative time, wRVU, and wRVU/hr were investigated using linear regression analysis. A secondary analysis using complication rate as an indicator for procedure complexity was performed to examine the relation between wRVUs and complication rates.ResultsFifty CPT codes containing 64,084 patients where only one code was reported were included in this analysis. The median operative time was 84 minutes, median wRVU was 11.23, and median wRVU/hour was 7.96. Linear regression analysis demonstrated a strong positive correlation between operative time and wRVU assignment (R2 = 0.805, P < .001). Further analysis found no correlation between operative time and wRVU/hr (R2 = 0.008, P = .525). Linear regression of wRVU/hr and complication rate showed a statistically significant positive correlation (R2 = 0.113, P = .017).ConclusionThis analysis suggests that compensation for otolaryngology procedures is positively correlated with operative time. Surgeries where more than one code is reported could not be evaluated, thus excluding some common combination of procedures performed by otolaryngologists.Level of Evidence4 Laryngoscope, 131:E395–E400, 2021
Engineering the Mammalian Cell Surface with Synthetic Polymers: Strategies and Applications
Authors: Arno Maria C. 
Published: August 2020

AbstractManipulating the surface of living cells represents a powerful tool by which to control cell behavior and provides a unique strategy to modulate cellular function and cell–cell interactions. Recent progress in this area has seen the development of robust and elegant approaches to selectively decorate the cell surface, leading to unprecedented advances in cellular manipulation and cell‐based therapies. Despite some impressive in vitro results, several obstacles remain to the broader application of some of these strategies, including their limited translation in vivo. In this review, the leading techniques used to introduce polymers at the plasma membrane of mammalian cells are discussed, focusing on strategies that generate a stable and homogeneous distribution of polymeric chains at the cell surface. Application of these strategies to control cell behavior and deliver cell‐based therapies to targeted tissues are highlighted.

Published: August 2020

AbstractSmart drugs, such as antibody‐drug conjugates, for targeted therapy rely on the ability to deliver a warhead to the desired location and to achieve activation at the same site. Thus, designing a smart drug often requires proper linker chemistry for tethering the warhead with a vehicle in such a way that either allows the active drug to retain its potency while being tethered or ensures release and thus activation at the desired location. Recent years have seen much progress in the design of new linker activation strategies. Herein, we review the recent development of chemical strategies used to link the warhead with a delivery vehicle for preferential cleavage at the desired sites.
Internal capital markets and bank holding company efficiency
Authors: Bressan Silvia , Rammerstorfert Margarethe , Weinmayer Karl 
Published: August 2020

AbstractBank Holding Companies and in particular their internal capital markets have been widely discussed in recent financial literature. The financial crisis especially brought regulatory intervention in financial markets into question. Empirical evidence suggests that bank holding companies have clear preferences for double leverage, which are not based on unambiguous and explicit economic foundations. In this article, we analyze the effects of equity, debt and double leverage on the efficiency of bank holding companies. We show that Bank Holding Company efficiency is negatively affected by equity financing from parents to subsidiaries and this effect is even more pronounced in case of double leveraging. Our findings indicate that further measures from regulators are necessary in order to prevent inefficient financing via double leverage, which may be used to circumvent regulatory capital requirements.

The common ground of these projects is the focus on German schools abroad and the qualitative research approach to firstly, translingual practices and language ideologies, secondly, multilingual educational biographies of students, and thirdly, transnational professional biographies of teachers.
‘What Shall We Sing Now, Amir?’ Developing a Voice through Translanguaging Pedagogy—An Ethnographic Research and Professional Training Project in Day-Care Centers and Schools
Authors: Panagiotopoulou Julie A. , Hammel Maria J. 
Published: August 2020

AbstractWith the aim of promoting inclusion and social justice in education, a new project supports (multilingual) professionals who address their own pedagogical practice of counteracting the disadvantages multilingual children face within a monolingual norm in Germany. The presentation of the project highlights how translanguaging as a pedagogy gives language-minoritized children a voice and as a sensitizing concept can be utilized for the analysis of project data and especially of ethnographic observations of learning and teaching practices.
‘We Learn Together’—Translanguaging within a Holistic Approach towards Multilingualism in Education
Authors: Duarte Joana , Günther-van der Meij Mirjam 
Published: August 2020

AbstractWithin two multilingual education projects in the north of the Netherlands a holistic model for multilingualism in education is being tested. This is done through design-based interventions in which in- and pre-service teachers, teacher trainers and researchers co-develop and evaluate multilingual activities for different school types. Results show that through experimenting in a safe environment teachers gradually embraced their pupils’ multilingualism. This contradicts earlier findings on teachers strongly favouring monolingual instruction and viewing migrant languages as a deficit.

Emerging Spanning Trees in the Work of Candilis–Josic–Woods
Authors: Athanasopoulos Georgios-Spyridon 
Published: August 2020

AbstractThis paper introduces the use of graph theory for the study of the work of Candilis–Josic–Woods. Α short introduction to the architects’ main strategies as members of Team Χ and CIAM (Congrès Internationaux d’Architecture Moderne) critics is given. Geometry and computational design methods for city planning and design are briefly discussed. Definitions of the minimum spanning tree, the shortest walk tree and the Steiner tree are then developed. The research projects these methods onto the main principles of Candilis–Josic–Woods’ planning and urban design approach to reinforce their strategic concepts. Distance-related and proximity-based ideas and their importance are sought in the literature related to Candilis–Josic–Woods’ body of work. Algorithmic based examples approximating a Euclidean Steiner tree are shown and discussed in the context of Candilis–Josic–Woods’ syntax. This paper argues that the generation of additional points through the use of a Euclidean Steiner tree algorithmic process is of importance in the work of Candilis–Josic–Woods as it allows for a systematic but emerging creation of hubs that can be activated as space on the one hand, and facilitate pedestrian circulation on the other. The project seeks to demonstrate the relevance of the triplet’s design methods to today’s complex networks of urban environments.
Akute virale Bronchiolitis und obstruktive Bronchitis bei Kindern
Authors: Schorlemer Christina , Eber Ernst 
Published: August 2020

ZusammenfassungAkute Bronchiolitis und obstruktive Bronchitis sind im Säuglings- und Kleinkindalter sehr häufige Krankheitsbilder. Sie werden durch Viren, v. a. respiratorisches Synzytialvirus und Rhinoviren, verursacht. Risikofaktoren für schwere Verläufe sind u. a. Frühgeburtlichkeit, Tabakrauchexposition und Immundysfunktionen. Die Diagnose kann durch Anamnese und klinische Untersuchung gestellt werden; Thorax-Röntgen und Laboruntersuchungen sind in der Regel nicht notwendig. Für die akute Bronchiolitis wurden viele therapeutische Ansätze propagiert, generell empfohlen sind aber nur supportive Maßnahmen (minimales Handling, Sicherstellung ausreichender Oxygenierung und Hydratation). Routinemäßig nicht empfohlen werden u. a. Antibiotika, Bronchodilatatoren, Kortikosteroide und Leukotrienrezeptorantagonisten. Kurz wirksame β2-Agonisten sind Therapie der 1. Wahl bei akuter obstruktiver Bronchitis. Bei häufigen und/oder schweren obstruktiven Bronchitiden kann zur Symptomkontrolle eine Therapie mit inhalativen Kortikosteroiden versucht werden. Die Entstehung von Asthma bronchiale ist jedoch durch keine medikamentöse Therapie zu verhindern.
Comparative study of eutectic Al-Si alloys manufactured by WAAM and casting

Published: August 2020

AbstractWire and arc additive manufacturing (WAAM) of metallic materials is expected to become part of the new industrial revolution. The possibilities for complex designs and superior mechanical properties can in many cases replace traditional manufacturing processes such as casting. In order to benchmark the properties of aluminium WAAM components, a comparative study was performed with two different casting techniques: permanent casting with steel mould and sand mould casting. Aluminium-silicon alloys with near eutectic composition were used for the comparison. Porosity levels, secondary dendrite arm spacing, grain size distribution, tensile strength and microhardness were considered for the comparison. The WAAM material exhibited superior mechanical properties originating from a finer dendritic and eutectic microstructure compared with the castings. A slight anisotropy in tensile ductility was observed in the WAAM material, probably due to a coarse microstructural zone between individual beads. All investigated materials had low levels of porosity, < 1% by area fraction. The comparative study has shown that WAAM of aluminium-silicon alloys is well suited for high-integrity applications.
Energy distribution of harmonic 1-forms and Jacobians of Riemann surfaces with a short closed geodesic
Authors: Buser Peter , Makover Eran , Muetzel Bjoern , Silhol Robert 
Published: August 2020

AbstractWe study the energy distribution of harmonic 1-forms on a compact hyperbolic Riemann surface S where a short closed geodesic is pinched. If the geodesic separates the surface into two parts, then the Jacobian variety of S develops into a variety that splits. If the geodesic is nonseparating then the Jacobian degenerates. The aim of this work is to get insight into this process and give estimates in terms of geometric data of both the initial surface S and the final surface, such as its injectivity radius and the lengths of geodesics that form a homology basis. The Jacobians in this paper are represented by Gram period matrices. As an invariant we introduce new families of symplectic matrices that compensate for the lack of full dimensional Gram-period matrices in the noncompact case.
Semi-Oblivious Chase Termination: The Sticky Case
Authors: Calautti Marco , Pieris Andreas 
Published: August 2020

AbstractThe chase procedure is a fundamental algorithmic tool in database theory with a variety of applications. A key problem concerning the chase procedure is all-instances termination: for a given set of tuple-generating dependencies (TGDs), is it the case that the chase terminates for every input database? In view of the fact that this problem is undecidable, it is natural to ask whether known well-behaved classes of TGDs, introduced in different contexts such as ontological reasoning, ensure decidability. We consider a prominent paradigm that led to a robust TGD-based formalism, called stickiness. We show that for sticky sets of TGDs, all-instances chase termination is decidable if we focus on the (semi-)oblivious chase, and we pinpoint its exact complexity: PSpace-complete in general, and NLogSpace-complete for predicates of bounded arity. These complexity results are obtained via a graph-based syntactic characterization of chase termination that is of independent interest.
On the Relation Between Structured d-DNNFs and SDDs
Authors: Bollig Beate , Farenholtz Martin 
Published: August 2020

AbstractStructuredd-DNNFs and SDDs are restricted negation normal form circuits used in knowledge compilation as target languages into which propositional theories are compiled. Structuredness is imposed by so-called vtrees. By definition SDDs are restricted structuredd-DNNFs. Beame and Liew (2015) as well as Bova and Szeider (2017) mentioned the question whether structuredd-DNNFs are really more general than SDDs w.r.t. polynomial-size representations (w.r.t. the number of Boolean variables the represented functions are defined on.) The main result in the paper is the proof that a function can be represented by SDDs of polynomial size if the function and its complement have polynomial-size structuredd-DNNFs that respect the same vtree.
