Published: November 2019

Significance
Programmable self-assembly of smart, digital, and structurally complex materials from simple components remains a long-standing goal of material science. Here, we propose an assembly platform where information is encoded into building blocks using arrays of magnets that induce specific binding. Similar to current state-of-the-art platforms, magnetic encoding can achieve controlled polymerization of lone panels, complementary binding of panel strands, and 3D assembly of panel nets. This platform, however, has several advantages over current methods in that the approach is scale-invariant, has tunable mechanical strength, and has high information capacity for programmable self-assembly. We envision that this approach will lead to the formation of structures that transmit information, act as mechanical elements, or function as machines across length scales.
Calling Mr Speaker ‘Mr Speaker’
Authors: Bull Peter , Fetzer Anita , Kádár Dániel Z. 
Published: November 2019

AbstractPrime Minister’s Questions (PMQs) in the UK House of Commons is a ritual event, governed by a cluster of conventions. Members of Parliament (MPs) must address their remarks to the Prime Minister (PM) through the medium of the Speaker of the House, who is responsible for maintaining order during debates, and determining which MP may speak next. Due to the sacred role of the Speaker and the prevalence of conventionalised conflict avoidance between the PM and those who ask challenging questions, PMQs resembles archaic tribal councils, in which rights and obligations prevail. Yet, the importance of conventionalised indirectness and the sacred role of the Speaker do not correlate with a lack of face-threats and challenges. PMQs represents an aggressive ritual setting in which the ritual roles and rules only offer a façade to package aggression, and indeed may operate as interactional resources whereby participants can even increase the efficiency of their verbal attacks. Thus, PMQs embodies a scene that ritual experts define as ‘anti-structural’ in character: in this setting, the normative expectation in daily life to avoid conflict is temporarily suspended, to such an extent that conflict has become the ritual norm and is regarded as quintessential to this parliamentary institution.
Short‐term effects of differential learning and contextual interference in a goalkeeper‐like task: Visuomotor response time and motor control

Published: November 2019

AbstractIn this experiment, we compared changes in visuomotor performance and motor control after a single session of differential learning (DL) and contextual interference (CI) in a reaching task to mimic goalkeeping. Subjects (nDL = nCI = 16) stood in front of a wall with six LED‐light targets that flashed on in a random order and subjects had to move their hand in front of it as fast as possible in order to extinguish the target. After the pre‐test subjects followed a DL or CI training session, followed immediately by a post‐test, followed by one hour of rest and a retention test. Performance and motor control were measured respectively by visuomotor response time (VMRT) and an Index of Motor Abundance (IMA; reflecting the strength of movement synergies) calculated with Uncontrolled Manifold analysis. A mixed‐effects Bayesian ANOVA model was used to evaluate differences in changes in both parameters between both training groups. Averaged over the six targets, the decrease in VMRT was stronger for DL than CI at the post‐test (interference effect) but not at retention. The IMA was on average increased at post‐ and retention test in both groups, indicating stronger synergies between the degrees‐of‐freedom. While the ANOVA for IMA was not conclusive, the changes were likely not different between both learning methods. Thus, while an interference effect was found for CI but not DL in terms of performance on the task, no such effect was observed on the behavioural level in terms of the strength of movement synergies.
Direct observation of paramagnetic spin fluctuations in LaFe13−xSix

Published: November 2019

Abstract
Spin fluctuations are a crucial driving force for magnetic phase transitions, but their presence usually is indirectly deduced from macroscopic variables like volume, magnetization or electrical resistivity. Here we report on the direct observation of spin fluctuations in the paramagnetic regime of the magnetocaloric model system LaFe11.6Si1.4 in the form of neutron diffuse scattering. To confirm the magnetic origin of the diffuse scattering, we correlate the temperature dependence of the diffuse intensity with ac magnetic susceptibility and x-ray diffraction experiments under magnetic field. Strong spin fluctuations are already observable at 295 K and their presence alters the thermal contraction behavior of LaFe11.6Si1.4 down to the Curie temperature of the first-order magneto-structural transition at 190 K. We explain the influence of the spin fluctuation amplitude on the lattice parameter in the framework of the internal magnetic pressure model and find that the critical forced magnetostriction follows Takashi’s spin fluctuation theory for itinerant electron systems.
Folding points of unimodal inverse limit spaces

Published: November 2019

Abstract
Williams’ work from the 1960s and 1970s provides a thorough understanding of hyperbolic one-dimensional attractors through their representation as inverse limits. In fact, point in a uniformly hyperbolic attractor has a neighbourhood that is homeomorphic to a Cantor set of open arcs. In order to understand the topology of non-uniformly hyperbolic attractors better, we study the existence and prevalence of points with more complicated local structures in simple models of planar attractors, focusing on unimodal inverse limits setting. Such points whose neighbourhoods are not homeomorphic to the product of a Cantor set and an open arc are called folding points. We distinguish between various types of folding points and study how the dynamics of the underlying unimodal map affects their structures. Specifically, we characterise unimodal inverse limit spaces for which every folding point is an endpoint.
Improving fast-particle confinement in quasi-axisymmetric stellarator optimization
Authors: Henneberg S A , Drevlak M , Helander P 
Published: November 2019

Abstract
A method to improve fast-particle confinement during quasi-axisymmetric stellarator optimization has been identified. Quasi-axisymmetric (qa) stellarator designs have improved neoclassical transport due to their special symmetry of the magnetic field strength. Previously, it has been shown that, in general, quasi-symmetry can only be obtained on one single flux surface (Garren and Boozer 1991 Phys. Fluids B 3 2805–21). Even though quasi-symmetry can be a crucial property of stellarator design, there is no established convention for choosing the flux surface on which this should be optimized. To address this question, the flux surface on which quasi-axisymmetry is optimized has been varied in a qa configuration. The optimal location was found to lie between half radius and the plasma edge, since this allows for two beneficial features: it increases the number of flux-surfaces with improved quasi-axisymmetry and it increases the volume enclosed by the flux surface with the best qa quality.

Abstract
Twin-field quantum key distribution(TF-QKD) protocol and its variants, such as phase-matching QKD, sending-or-not-sending QKD and no phase post-selection TF-QKD(NPP-TFQKD), are very promising for long-distance applications. However, there are still some gaps between theory and practice in these protocols. Concretely, a finite-key size analysis is still missing, and the intensity fluctuations are not taken into account. To address the finite-key size effect, we first give the key rate of NPP-TFQKD against collective attack in finite-key size region and then prove it can be against coherent attack. To deal with the intensity fluctuations, we present an analytical formula of 4-intensity decoy state NPP-TFQKD and a practical intensity fluctuation model. Finally, through detailed simulations, we show NPP-TFQKD can still keep its superiority of high key rate and long achievable distance.
Dynamic characterization of beating sinusoidal wave oscillations in a thin-slice solid-state laser with coupled orthogonally polarized transverse modes
Authors: Otsuka Kenju 
Published: November 2019

Abstract
Dynamic characterization of self-induced beating sinusoidal wave (BSW) oscillations and related phenomena, which were previously explored in a thin-slice dual-polarization solid-state laser operating in the regime of incomplete mode-locking of orthogonally polarized transverse eigenmodes, namely, a quasi-locked state Otsuka (2018 Laser Phys. Lett. 15 075001), is performed in terms of the amplitude correlation coefficient and intensity circulation among various orthogonally polarized mode pairs. Polarization-dependent symmetry-breaking featuring a nonreciprocal intensity flow for different orthogonally polarized mode pairs operating in the BSW state are found. The singular state is hidden in a nonlinear system where a perfect mode-locked BSW state with a large amplitude correlation coefficient featuring reciprocal intensity flow is established for a transverse mode pair possessing particular polarization directions that are related to the intensity ratio of orthogonally polarized transverse eigenmodes. Self-organized chaos synchronization is shown to take place for such a single pair of transverse modes subjected to self-mixing modulations.
Carrier-envelope-phase dependence of harmonics induced by a few-cycle vortex laser
Authors: Zhang Chaojin , Liu Chengpu 
Published: November 2019

Abstract
When a few-cycle vortex laser interacted with an inversion-symmetric atomic-like system, beyond the usual odd-order harmonics, some additional components also occur. The detailed numerical investigation on their transverse field distributions discloses that they depend sensitively on the carrier-envelope-phase (CEP) and the rotation period of the transverse distribution is 2π. This could be used to directly determine the CEP value of an incident pulse, unique without falling back on specific polar molecules or static electric fields.

We investigate the mass-shift of P-wave charmonium (

,

,

, and

) states in magnetized hot asymmetric nuclear matter using the unification of QCD sum rules (QCDSR) and the chiral

model. Within QCDSR, we use two approaches, i.e., the moment sum rule and the Borel sum rule. The magnetic field induced scalar gluon condensate

and the twist-2 gluon operator

calculated in the chiral

) model are utilised in QCD sum rules to calculate the in-medium mass-shift of the above mesons. The attractive mass-shift of these mesons is observed, which is more sensitive to magnetic field in the high density regime for charmonium, however less so for bottomonium. These results may be helpful to understand the decay of higher quarkonium states to the lower quarkonium states in asymmetric heavy ion collision experiments.

Abstract
Akway (Drimys beccariana, Gibbs) is a plant endemic to Papua highlands contained in Manokwari. D. beccariana is used for traditional malaria treatment in West Papua. The methanol extract of stem bark of D. beccariana showed antimalarial activity against Plasmodium falciparum parasites, in vitro. Methanol extract of D. beccariana is partitioned between water and n-hexane (1:9), and ethyl acetate. Furthermore, ethyl acetate extract was separated through several combination of chromatography techniques on silica gel, resulting in three known compounds (1-3). The chemical structures of compounds (1-3) were identified based on IR, UV/Vis, 1H NMR and 13C NMR, and MS data as 5,3’-dihydroxy-7,4’-dimethoxyflavone (1), 5,7-dihydroxy-4’-methoxyflavone (2), and 5-hydroxy-7,3’,4’-trimethoxyflavone (3). Compounds 1-3 showed strong antiplasmodium against 3D7 strain of P. falciparum with IC50 values of 0.002, 0.005, and 0.001 micro Molar, respectively. This result indicates that stem bark of D. beccariana is a promising source of antimalarial agents, and merits further investigation.

Number of Failures for Weibull Hazard Function witha Fuzzy Shape Parameter
Authors: Husniah H , Widjajani  , Rohmana  , Supriatna A K 
Published: November 2019

Abstract
Number of failures play important role in maintenance strategy for industrial equipment, either repairable or non-repairable ones. There are several form of known distribution used to model the failures of an industrial equipment. Weibull distribution, and its hazard function, is among the most used distribution. Most maintenance models in literature mainly consider certain or crisp condition in a deterministic form. However, many real phenomena seem do not suitable to model in such certain or crisp condition. One approach to model a possibilistic uncertainty is by applying the fuzzy number theory. In this paper, we discuss the Weibull hazard function by assuming a fuzzy shape parameter. We look for the number of failures generating by the function using two different methods. The first one assumes that the fuzziness of the shape parameter propagates to the number of failures with the same form of fuzzy number membership. The second one use the fuzziness of the shape parameter in the computation of the number of failures directly, through the concept of alpha-cut or alpha-level. Some comparisons regarding these approaches are presented.
