A Review of the Phytochemistry, Traditional Uses, and Biological Activities of the Genus Ballota and Otostegia
Authors: Rosselli Sergio , Fontana Gianfranco , Bruno Maurizio 
Published: June 2019

AbstractThe 2 genera Ballota and Otostegia, belonging to the Lamiaceae family, are closely related taxonomically and found mainly in the Mediterranean area, Middle East, and North Africa. Since ancient times, they have been largely employed in traditional medicine for their biological properties such as antimicrobial, anti-inflammatory, antispasmodic, insecticidal, anti-malaria, etc. Phytochemical investigations of Ballota and Otostegia species have revealed that diterpenoids are the main constituents of the genera. A large number of flavonoids and other metabolites were also identified. This review, covering literature from 1911 up to 2018, includes traditional uses, chemical profiles (both of volatile and nonvolatile metabolites), and biological properties of all the taxa of these 2 genera studied to date.

Significance
The growing availability of 3D manufacturing methods has implications across diverse applications, from ship building to microelectronics processing. Systems with sizes in the micrometer and millimeter regime are of particular interest, where few techniques offer the necessary range of capabilities in throughput, materials compatibility, and design versatility. Recently reported techniques for mechanically guided 3D assembly offer many appealing features, but limitations remain, such as those in formation of structures with chiral features and morphable shapes. Here we present concepts that allow controlled introduction of twisting into 3D mesostructures. The results provide access to many classes of previously unachievable 3D architectures, as illustrated through nearly 2 dozen examples in diverse materials and across a wide span of length scales.

Published: June 2019

Abstract

GlobalBioIm is an open-source MATLAB® library for solving inverse problems. The library capitalizes on the strong commonalities between forward models to standardize the resolution of a wide range of imaging inverse problems. Endowed with an operator-algebra mechanism, GlobalBioIm allows one to easily solve inverse problems by combining elementary modules in a lego-like fashion. This user-friendly toolbox gives access to cutting-edge reconstruction algorithms, while its high modularity makes it easily extensible to new modalities and novel reconstruction methods. We expect GlobalBioIm to respond to the needs of imaging scientists looking for reliable and easy-to-use computational tools for solving their inverse problems. In this paper, we present in detail the structure and main features of the library. We also illustrate its flexibility with examples from multichannel deconvolution microscopy.
Source term calculation and validation for 18F-production with a cyclotron for medical applications at HZDR
Authors: Konheiser J , Müller S E , Magin A , Naumann B , Ferrari A 
Published: June 2019

Abstract
In this document we present the calculation and experimental validation of a source term for 18F-production with a cyclotron for medical applications operating at 18 MeV proton energy and 30 μA proton current. The Monte Carlo codes MCNP6 and FLUKA were used for the calculation of the source term. In addition, the radiation field around the 18O-enriched water target was simulated with the two codes. To validate the radiation field obtained in the simulation, an experimental program has been started using activation samples which are placed close to the water target during an 18F-production run of the cyclotron. After the irradiation, the samples are analysed and the resulting activation is compared to Monte Carlo calculations of the expected sample activation. We find good agreement between simulations and experimental results, with most calculation to experiment (C/E) ratios well between 0.6 and 1.4.
Practical decoy-state method for twin-field quantum key distribution
Authors: Grasselli Federico , Curty Marcos 
Published: June 2019

Abstract
Twin-field (TF) quantum key distribution (QKD) represents a novel QKD approach whose principal merit is to beat the point-to-point private capacity of a lossy quantum channel, thanks to performing single-photon interference in an untrusted node. Indeed, recent security proofs of various TF-QKD type protocols have confirmed that the secret key rate of these schemes scales essentially as the square root of the transmittance of the channel. Here, we focus on the TF-QKD protocol introduced by Curty et al, whose secret key rate is nearly an order of magnitude higher than previous solutions. Its security relies on the estimation of the detection probabilities associated to various photon-number states through the decoy-state method. We derive analytical bounds on these quantities assuming that each party uses either two, three or four decoy intensity settings, and we investigate the protocol’s performance in this scenario. Our simulations show that two decoy intensity settings are enough to beat the point-to-point private capacity of the channel, and that the use of four decoys is already basically optimal, in the sense that it almost reproduces the ideal scenario of infinite decoys. We also observe that the protocol seems to be quite robust against intensity fluctuations of the optical pulses prepared by the parties.
Minimal model for tidal bore revisited
Authors: Berry M V 
Published: June 2019

Abstract
This develops a recent analysis of gentle undular tidal bores (2018 New J. Phys.
20 053066) and corrects an error. The simplest linear-wave superposition, of monochromatic waves propagating according to the shallow-water dispersion relation, leads to a family of profiles satisfying natural tidal bore boundary conditions, involving initial smoothed steps with different shapes. These profiles can be uniformly approximated to high accuracy in terms of the integral of an Airy function with deformed argument. For the long times corresponding to realistic bores, the profiles condense asymptotically onto the previously obtained integral-Airy function with linear argument: as the bore propagates, it forgets the shape of the initial step. The integral-Airy profile expands slowly, as the cube root of time, rather than advancing rigidly. This ‘minimal model’ leads to simple formulas for the main properties of the profile: amplitude, maximum slope, ‘wavelength’, and steepness; and an assumption about energy loss suggests how the bore weakens as it propagates.
Maximum Power Point Tracking of PV Systems Based On a Novel Adaptive Variable Step Size INC MPPT Method
Authors: WeiFeng You , Yan Cui 
Published: June 2019

Abstract
In the future solar energy will become a very important green energy. Maximum power point (MPP) tracking (MPPT) technology is widely used in solar photovoltaic (PV) systems to generate peak power for PV arrays that depend on solar irradiation and ambient temperature. Literature[1] shows that the maximum power point tracking (MPPT) technology can improve the efficiency of photoelectric conversion by more than 20% and the economic cost is relatively low. Based on PROTUES, the output characteristics of PV arrays under different shadow conditions are simulated and the rule between local maximum power point and open circuit voltage is obtained. Among all the MPPT strategies, the incremental conductance (INC) algorithm and perturb and observe (P&O) algorithm are widely used due to the high tracking accuracy at steady state and easy implementation.In this paper, a novel adaptive variable step size INC MPPT method is proposed according to the above rule. This algorithm not only has the advantage of INC, but also can automatically adjust the step size to track the maximum power point of PV arrays. Compared with the adaptive perturb and observe (P&O) algorithm, the proposed approach can effectively improve the MPPT steady-state response speed and accuracy simultaneously. The theoretical analysis and design principle of the proposed algorithm are presented in this paper. The simulation results show that the algorithm can accurately track the maximum power point (MPP) with shadow. The average tracking time is only 0.13 seconds, and the power tracking efficiency reaches 98%.

Abstract
The water impermeability of the rapid setting conventional and polymer-modified waterproof mortars is systematically compared in this paper. Additionally, the self-repairing performance of the rapid setting polymer-modified waterproof mortar is highlighted. Compared with the rapid setting conventional waterproof mortar, the rapid setting polymer-modified waterproof mortar possesses better water impermeability. Furthermore, the presence of the specific reactive chemical compound is justified to improve the secondary water impermeability and thus the self-repairing property of the rapid setting polymer-modified waterproof mortar.

Authors: Zhao Hongyuan , Liu Xiaodong , Zhao Wei , Wang Gong , Liu Bingshan 
Published: June 2019

Abstract
Continuous fiber reinforced composites have excellent mechanical properties, but traditional processes are costly, complex to form, have a long production cycle, and are only suitable for relatively simple structures, which limits the wider application of the material. Fuse Deposition Modeling(FDM) 3D printing has the advantages of simple process, fast molding, low cost, and the ability to manufacture high-complexity structures, which provides the possibility of low-cost and rapid prototyping of composite materials. In this paper, several FDM 3D printing processes for continuous fiber composites are reviewed, and the effects of some related process parameters on the properties of the composites are analyzed. Finally, the problems of FDM 3D printing continuous fiber reinforced composites are pointed out.

Abstract
The aims of this study were to describe the application of guided inquiry with a scaffolding strategy based on lesson study to improve critical thinking skills. This type of research is classroom action research. The results showed that guided inquiry with a scaffolding strategy based on lesson study can improve critical thinking skills. Guided inquiry is an inquiry learning model that actively involves students in the learning process directly and improves mastery of concepts. Scaffolding is learning in which students are given a number of assistance during the early stages of learning and then reduce assistance slowly and give responsibility to students to carry out the specified learning. Lesson Study can reflect the teaching and learning process in the classroom and has the potential to build a learning community in schools that results in improvements in the learning process and increases teacher knowledge that focuses on students and the material taught. The results showed that guided inquiry with a scaffolding strategy based on lesson study can improve critical thinking skills in applying indicators from cycle I to cycle II around 27.5%, analysing from cycle I to cycle II around 15%, using data from cycle I to cycle II around 15% and synthesized from cycle I to cycle II around 25%. It is hoped that further research will apply other models to improve critical thinking skills.
