SignificanceTherapy-loaded nanoparticles may be directed to the brain by functionalization with ligands targeting blood–brain barrier (BBB)-associated proteins. However, such targeting strategies have inherent brain-specificity limitations, as the target proteins are also significantly expressed in peripheral organs. Here, we present a counterintuitive targeting strategy that exploits the high impermeability of the BBB to selectively retain ligand labels on the surface of brain endothelium. Nanoparticles capable of binding the displayed ligands are consequently directed specifically to the brain microvasculature. This two-step targeting strategy paves the way to overcome the peripheral “off-target” nanoparticle accumulation, increasing the clinical translation of nanoparticle-based therapies. In addition, it shifts the identification of brain-target proteins from focusing on differential expression to instead focus on differential endocytic rates.

Significance
Solution processing of high-performance, high-Ga-content IGZO thin-film transistors (TFTs)—or compositionally simpler and, hence, technologically more desirable indium gallium oxide (IGO) TFTs—remains challenging and an impediment to manufacturing low-temperature, solution-processed metal oxide electronics. Here, the performance of aqueous solution-processed IGO TFTs is greatly enhanced with polyvinyl alcohol in the precursor solution, yielding a >70-fold increase in electron mobility. By achieving optimal H doping and conversion from six- to four-coordinate Ga, PVA addition suppresses deep trap defect localization. This result not only offers a route to high-performance, ultra-stable metal oxide semiconductor electronics with simple binary compositions, but also provides powerful tools to probe H locations in amorphous metal oxides via a combination of experimental and theoretical approaches.
Populism in performance?
Authors: Montgomery Martin 
Published: July 2020

Abstract
Much commentary on the discourse of Donald Trump’s populist appeal has tended to focus on his use of Twitter, to the relative neglect of his campaign rallies. Yet his campaign rallies during the presidential election were arguably crucial for delivering the votes which secured his victory. Members of his own team, and Trump himself, certainly thought so.
Since the election Trump has continued to campaign in rallies in key states with increasing vigour, attracting
large audiences as the second term elections in 2020 approach.
These large-scale public events confirm the bond between Trump and his base. But they also require us to re-focus attention beyond Trump as an individual figure to the process of mutual engagement between him and his highly active and vocal
audience.
This article, by examining the overall communicative behaviour of participants at his rallies asks: “Is the
audience Trump’s creation or is Trump the audience’s creation?”
German discourse particles in the second language classroom
Authors: Trotzke Andreas , Bidese Ermenegildo , Moroni Manuela Caterina 
Published: July 2020

Abstract
One of the main pedagogical objectives for language learners at high proficiency levels is to use ‘cohesive
devices’ when writing a text or conducting a conversation. Usually, curricula stress the importance of clause-internal cohesion
(by means such as connectives: and, but, when, because, etc.).
By contrast, we stress the importance of cohesion at the level of the dialogue and in this context focus on discourse (aka
‘modal’) particles as a means to yield cohesion at that level. In this domain, German discourse particles represent a challenging
learning objective for second language learners of German. This paper explores some production patterns of German discourse
particles in L2 German by L1 Italian learners. We show that looking at those elements can provide new insights because these
elements allow us to tease apart problems within syntax as compared to the lexicon-pragmatics interface in second language
learning.
Dimensional analysis in relativity and in differential geometry
Authors: Mana P G L Porta 
Published: July 2020

Abstract
This note provides a short guide to dimensional analysis in Lorentzian and general relativity and in differential geometry. It tries to revive Dorgelo and Schouten’s notion of ‘intrinsic’ or ‘absolute’ dimension of a tensorial quantity. The intrinsic dimension is independent of the dimensions of the coordinates and expresses the physical and operational meaning of a tensor. The dimensional analysis of several important tensors and tensor operations is summarized. In particular it is shown that the components of a tensor need not have all the same dimension, and that the Riemann (once contravariant and thrice covariant) and Ricci (fully covariant) curvature tensors are dimensionless. The relation between dimension and operational meaning for the metric and stress–energy–momentum tensors is discussed; and the main conventions for the dimensions of these two tensors and of Einstein's constant are reviewed. A more thorough and updated analysis is available as a preprint.
Improvement of Bi doping in ZnO nanocrystals by co-doping with Al: crystal geometry calculations and photocatalytic activity
Authors: Emara Mahmoud M , Hassan Abdelhamied A , El-Dissouky Ali , Patten P Gregory Van 
Published: July 2020

Abstract
In this work we demonstrate enhancement in visible-light photocatalytic activity (PCA) of ZnO nanoparticles (NPs) with minimal attenuation of visible light transmittance. This approach can benefit numerous optoelectronic and photocatalytic applications. ZnO NPs were p-n co-doped with Al and Bi to improve Bi doping into the ZnO crystal. Al- and/or Bi-doped ZnO was coprecipitated by ammonia from aqueous nitrate solutions of Zn2+, Al3+, and Bi3+, followed by microwave heating. Doping concentrations in Al- and Bi- doped ZnO (AZO and BZO) and Al/Bi co-doped ZnO (ABZO) were 1, 3, 5, and 7 mole %. The resulting NPs were characterized by XRD, TEM, EDS, BET, and UV-visible absorption. While EDS shows that almost all added Bi was incorporated into the ZnO, XRD analysis of BZO reveals formation of α-Bi2O3 as a secondary phase due to the poor Bi solubility in ZnO. Co-doping of Al with Bi suppressed α-Bi2O3 formation and increased Bi solubility in ZnO. XRD-based calculations of the lattice constants and deformation strain, stress, and energy all show insertion of Al and/or Bi into the crystal with different extents according to the dopants’ solubilities into ZnO. AZO and BZO NPs had E
g lowered by 0.05–1.39 eV and 0.30–0.70 eV, respectively, relative to ZnO. On the other hand, ABZO had E
g reductions of only 0.01–0.20 eV due to formation of acceptor-donor complex through co-doping. ABZO gave higher PCA enhancements with respect to E
g reductions (Δk
photo/–ΔE
g) than either AZO and BZO, with values up to 370, 126, and 13 min–1 eV–1, respectively.
Characterization of an operational quantum resource in a critical many-body system
Authors: Sarkar S , Mukhopadhyay C , Bayat A 
Published: July 2020

Abstract
Quantum many-body systems have been extensively studied from the perspective of quantum technology, and conversely, critical phenomena in such systems have been characterized by operationally relevant resources like entanglement. In this paper, we investigate robustness of magic (RoM), the resource in magic state injection based quantum computation schemes, in the context of the transverse field anisotropic XY model. We show that the the factorizable ground state in the symmetry broken configuration is composed of an enormous number of highly magical H states. We find the existence of a point very near the quantum critical point where magic contained explicitly in the correlation between two distant qubits attains a sharp maxima. Unlike bipartite entanglement, this persists over very long distances, capturing the presence of long range correlation near the phase transition. We derive scaling laws and extract corresponding exponents around criticality. Finally, we study the effect of temperature on two-qubit RoM and show that it reveals a crossover between dominance of quantum and thermal fluctuations.

Abstract
The PK-4 laboratory consists of a direct current plasma tube into which microparticles are injected, forming a complex plasma. The microparticles acquire many electrons from the ambient plasma and are thus highly charged and interact with each other. If ion streams are present, wakes form downstream of the microparticles, which lead to an attractive term in the potential between the microparticles, triggering the appearance of microparticle strings and modifying the complex plasma into an electrorheological form. Here we report on a set of experiments on compressional waves in such a string fluid in the PK-4 laboratory during a parabolic flight and on board the International Space Station. We find a slowing of acoustic waves and hypothesize that the additional attractive interaction term leads to slower wave speeds than in complex plasmas with purely repulsive potentials. We test this hypothesis with simulations, and compare with theory.

Abstract
Tumpeng is one of the ceremonial facilities used almost in every Hindu religious ceremony. Many people take advantage of these opportunities as a home-based business. At present the craftsmen encounter obstacles in the process of drying the cone. Currently the drying process still uses the manual method, namely by drying it by utilizing direct sunlight. In the previous research, the product planning for cone drying machine has been carried out, where the results obtained from this study are an increase in the productivity of the drying machine from the drying machine which was previously used by the cone maker of 683.33%. Although there is an increase in the productivity of the drying machine, the air distribution at each level of the rack is not evenly distributed, so the drying machine needs to be reviewed so that the air distribution in the drying chamber becomes more evenly distributed between the racks. From the results of studies conducted by the hot air entering the drying chamber from the results of the previous engine design, it is likely that conditions on level 1 shelves and level 2 shelves have temperatures that are quite high compared to other rack levels because this air is circulated at level 3, 4.5 and 6. To get the air distribution between the level of the rack evenly, it is necessary to do a redesign of the tool. The alternative that can be done is by circulating hot air from rack 1 to rack 6, another alternative is to try variations in air distribution in the drying chamber by varying the cone seat holes.
The redesign method that was carried out was to replace the existing distribution before the air out of the level 3 blower in the rack was changed to the air out of the level 1 rack entry blower, and the cone seat was made varied by random holes, concentric holes and zigzag holes.
From the results of engine redesign after testing the air distribution in the drying chamber with a random hole stacking model, the highest temperature is found in almost all shelf levels, except at the level 1 rack the highest temperature is achieved by a concentric perforated pedestal model that reaches 183 °C. Judging from the hot air distribution, the randomly hollowed cone seat model provides a more even distribution of hot air compared to the concentric and zigzag hollow cone seat model.
