All-inorganic CsPbX3 (X = Cl, Br, I) perovskite nanocrystals (NCs) as promising optoelectronic materials have attracted tremendous research interest because of their intense photoluminescence, broad absorption, and tunable bandgap. Even with these fascinating characteristics, their practical applications are still suffering from the presence of toxic lead and inadequate stability. Herein, we successfully synthesize CsNiCl3 NCs in a comparatively low-temperature route for the first time. By Cu+ and In3+ doping, CsNiCl3 NCs can be converted from non-luminous into photoluminescent materials. The broad green fluorescence emission at 530 nm of CsNiCl3 NCs with high luminescence intensity and quantum yield (42.2%) is achieved. Broad band emission with a large Stokes shift can be attributed to the recombination process of self-trapped excitons (STEs). The transient fluorescence spectra of the doped CsNiCl3 NCs show two ultra-long lifetimes of about 50 and 120 µs, which are assigned to the STE recombination, indicating that the nonradiative recombination process is suppressed after doping. Our research provides an innovative method for developing environmentally friendly lead-free metal halide NCs.
A statistical investigation of the rate constants for the H+ + HD reaction at temperatures of astrophysical interest
Authors: González-Lezana Tomás , Hily-Blant Pierre , Faure Alexandre 
Published: November 2022

The H+ + HD(v, j) reaction has been investigated in detail by means of a statistical quantum method. State-to-state cross sections and rate constants for transitions between reactants and rovibrational states HD(v′, j′) of the product arrangement with energies below 0.9 eV collision energy [that is, HD(v = 0, j = 0–11) and HD(v = 1, j = 0–6)] have been calculated. For the other product channel, D+ + H2(v′, j′), rovibrational states up to (v′ = 0, j′ = 9) have been considered for the calculation of the corresponding thermal rate. Present predictions are compared with previously reported theoretical and experimental rates. Finally, cooling functions for HD due to proton and atomic hydrogen collisions are computed in the low-density regime. We find that the much larger HD–H+ cooling function, as compared with that of HD–H, does not compensate for the low H+/H abundance ratio in astrophysical media so that HD cooling is dominated by HD–H (or HD–H2) collisions.

Context Across much of its geographic range, the masked water snake, Homalopsis buccata, is harvested each year in large numbers, questioning the sustainability of that offtake. Aims To quantify abundance and demography of water snakes in anthropogenically disturbed habitats in an area of West Java, where these snakes are subject to intensive harvest. Methods We accompanied professional snake-collectors, and conducted our own surveys of ponds and irrigation canals, to record the numbers and attributes (species, sex, size, etc.) of snakes that were captured using a variety of methods. Key results Snakes of several species were abundant, with mean capture rates of 32 666 snakes km−1 of irrigation canals, and 57 501 snakes km−2 of fishponds (9500 and 43 788 for H. buccata alone). Sex ratios of H. buccata were female-biased in ponds but not irrigation channels. Ponds underlain by deeper mud contained more snakes. Collecting methods varied among habitat types, in a way that reduced collateral risk to commercially farmed fish in ponds. Conclusions These water snakes are extremely abundant in Java, despite high levels of historical and continuing harvest. The inference of low population sizes for H. buccata in Indonesia, as presented in the IUCN Red List, is erroneous. Implications An ability to utilise anthropogenic resource subsidies (in this case, fish farmed in village ponds) allows some native predator species to attain remarkably high abundances, and to withstand intense efforts at harvesting.

Published: November 2022

The management of biofilm-related infections is a challenge in healthcare, and antimicrobial photodynamic therapy (aPDT) is a powerful tool that has demonstrated a broad-spectrum activity. Nanotechnology has been used to increase the aPDT effectiveness by improving the photosensitizer’s delivery properties. NewPS is a simple, versatile, and safe surfactant-free nanoemulsion with a porphyrin salt shell encapsulating a food-grade oil core with promising photodynamic action. This study evaluated the use of NewPS for aPDT against microorganisms in planktonic, biofilm, and in vivo models of infected wounds. First, the potential of NewPS-mediated aPDT to inactivate
Streptococcus pneumoniae
and
Staphylococcus aureus
suspensions was evaluated. Then, a series of protocols were assessed against
S. aureus
biofilms by means of cell viability and confocal microscopy. Finally, the best biofilm protocol was used for the treatment of
S. aureus
in a murine-infected wound model. A high NewPS-bacteria cell interaction was achieved since 0.5 nM and 30 J/cm
2
was able to kill
S. pneumoniae
suspension. In the
S. aureus
biofilm, enhanced efficacy of NewPS-aPDT was achieved when 100 µM of NewPS was applied with longer periods of incubation at the light dose of 60 J/cm
2
. The best single and double-session protocol reduced 5.56 logs and 6.03 logs, respectively, homogeneous NewPS distribution, resulting in a high number of dead cells after aPDT. The in vivo model showed that one aPDT session enabled a reduction of 6 logs and faster tissue healing than the other groups. In conclusion, NewPS-aPDT may be considered a safe and effective anti-biofilm antimicrobial photosensitizer.
On the origins of multiple exponence in Crow
Authors: Ko Edwin 
Published: November 2022

Abstract
Multiple exponence is a phenomenon in which morphemes that encode a given piece of information are realized
multiple times within a single word. Unlike other members of the Siouan language family spoken across North America, Crow
possesses a set of modal auxiliaries that display multiple exponence of subject person agreement. I show that one source of
multiple exponence in Crow is the grammaticalization of the inflectional future from the motion verb arrive there, which
brings with it its own agreement prefixes. Multiple exponence then extended to compound modals containing the inflectional future
and finally to a morphologically unrelated modal – a distinct case of multiple exponence begetting additional multiple exponence.
Thus, this study contributes to the broader understanding of the diachronic pathways to multiple exponence.
Serbian Progressive Party’s shameless normalization of expressing sycophancy toward the leader
Authors: Jeftić Ljerka 
Published: November 2022

Abstract
The notion of shameless normalization is applied in the paper to argue that the Serbian ruling
party’s press releases introduce shameless normalization of expressing sycophancy toward the leader. Within the
framework of critical (political) discourse analysis postulating that social actors’ use of language is vested with interests that
need to be linguistically managed, the paper focuses on how the proposed strategies in political discourse – coercion,
legitimisation and (mis)representation – manage the interest of the authors of press releases in realization of sycophancy. The
analysis shows that the shameless normalization of sycophancy is realized by coercing the recipients to accept the exclusive right
of the leader to represent the homogenized people of Serbia (the ingroup). This exclusive right is legitimized through positive
representation of the leader as the self of the ingroup. Such legitimisation is enabled by misrepresentation both in terms of
quality and quantity of the information conveyed.
Turn design in talk-in-interaction in a foreign language – Collaborative turn constructions and ellipses in casual
conversations among German high-school learners of English
Authors: Haselow Alexander 
Published: November 2022

Abstract
This study explores the ability of advanced adolescent German learners of English to optimize turn design for
talk-in-interaction, focusing on collaborative turn constructions and ellipses. Data deriving from recorded conversations
conducted in the foreign language among German learners of English are compared to conversations between native speakers of
British English and integrated into a diagnostic approach that helps identify deficits in the field of interactional skills. The
results show that the two syntactic formats occur less frequently in learner conversations, which indicates that learners are less
likely to use syntactic resources to bind their contribution immediately to prior talk or to the situational context. It is argued
that this has a negative effect upon the sequential fit of turns and that conversational practice targeted toward a syntax for
conversation would help learners achieving a more fluid interplay of conversational moves.
The effect of quaternary ammonium salts with different chain lengths on copper filling behavior in blind holes of printed circuit board

Published: November 2022

Abstract
The rapid and defect free blind hole copper super filling is the key technology to ensure the quality and development of printed circuit boards (PCBs). The linear quaternary ammonium compounds with a low molecular weight are expected to act as a potential suppressor for blind hole copper filling. Here, three quaternary ammonium salts with different molecular chain lengths (the dodecyl trimethyl ammonium chloride, the cetyl trimethyl ammonium chloride and the stearyl trimethyl ammonium chloride) were selected to study the effects of the molecular chain length of quaternary ammonium salt on the copper filling behavior of the PCB blind holes. The electrochemical results show that the three quaternary ammonium salts show greater inhibition ability on copper deposition compared with the traditional additives (polyethylene glycol (PEG) and Cl−) and furthermore, the suppressor effect becomes stronger with the increase of molecular weight. The blind hole copper filling experiment of PCB is also carried out to study the copper filling capacity of three quaternary ammonium salts. The filling experiment reveals that compared with the traditional suppressors (PEG and Cl−), the filling quality of blind hole copper is significantly improved when the three quaternary ammonium salts are used as suppressors. Moreover, under the coordination of accelerator (bis (3-sulfopropyl) disulfide (SPS)), the three quaternary ammonium salts can realize more rapid copper super filling without chloride ion in the electrolyte. Cross-section and surface morphological analysis further illuminates that the quaternary ammonium salt as an suppressor can also more effectively inhibit the deposition of copper on the PCB surface and reduce the roughness of the copper layer. The present results imply that quaternary ammonium salts have greater advantages for copper filling and are expected to replace traditional suppressors as new suppressors.

Published: November 2022

Abstract
The ex situ sputtered AlN buffer and GaN epilayer grown on top of it by metalorganic chemical vapor deposition were studied comprehensively by a variety of techniques including atomic force microscope, high resolution x-ray diffraction, Raman and x-ray photoelectron spectroscopy characterizations. It exhibited that the AlN buffer deposited by using sputtering technique could be oxidized with exposure in atmosphere. Such oxidation phenomenon significantly influences the characteristics of GaN epilayer, for example leading to poor surface morphology, high dislocation density, and large compressive stress. This study demonstrated the effect of oxygen impurities on GaN growth and has an important guiding significance for the growth of high-quality III-nitride related materials.

Abstract
Quality assurance program (QAP) implementation in mammography is a key aspect to guarantee the acquisition of -quality images and, thus, an opportune diagnosis of breast cancer. A QAP involves planned and systematic actions, such as quality control (QC) tests that will produce consistently high-quality images, while considering low radiation exposure for stakeholders. Currently, there is poor evidence of the current QAP implementation status in developing countries, particularly in Latin America. In this work, 47 Mexican digital mammography facilities were evaluated in terms of their QAP implementation’s current status during the period October 2021 to April 2022. A survey of three key indicators of compliance/non-compliance with QAPs was carried out. Also, 17 QC test parameters were assessed in all mammography units according to an international framework. The Kruskal–Wallis test, McNemar test, and Spearman correlation were used to identify the significant correlation between the QC tests and QAP indicators. Statistical analysis showed a significant positive correlation between the QAP indicators and QC parameters that were evaluated, especially associated with an increase in image quality. Almost 90% of the facilities evaluated failed in some QAP indicators, and only 44.68% of the facilities had an updated and current QAP implemented. Successful QAP implementation directly impacted on the QC mammography test results, particularly in terms of image quality, thus conditioning a successful mammography acquisition chain. The results obtained in this work suggest that better regulations need to be implemented to guarantee QAP surveillance, which could mean an increase in opportune diagnosis and management of breast cancer, with improved radiological safety for patients and occupational exposure personnel.
Estimation of state of charge integrating spatial and temporal characteristics with transfer learning optimization
Authors: Zhang Yiwei , Liu Kexin , Chuang Yutong , Zhang Jiusi 
Published: November 2022

AbstractState of charge (SOC) estimation of lithium-ion batteries is of vital significance for the control strategy in battery management systems. To integrate the spatial and temporal characteristics of the data and to accomplish the transfer of knowledge, a novel convolutional neural network-bidirectional long short-term memory network based on transfer learning optimization (CNN-BiLSTM-TF) is proposed to estimate the SOC. Specifically, the spatial and temporal features hidden in the data are learned through CNN and BiLSTM, respectively. Furthermore, the CNN-BiLSTM network is established under one working condition and transferred to other working conditions through transfer learning, from which the SOC can be estimated online. A lithium-ion battery data set is applied to verify the proposed SOC estimation approach. The results of a case study demonstrate that the estimation performance of CNN-BiLSTM-TF is better than some existing approaches.
Design and performance investigation of a novel 3DOF compact MR damper

Published: November 2022

Abstract
Magnetorheological (MR) fluid based dampers have been established as an alternative to classical hydraulic dampers with proportional electromagnetic valves under vibration processes which demand adaptive damping forces. Almost all MR-dampers are spatially 1-degree-of-freedom (DOF) dampers, having only one axis or direction of damping force generation. In many technical applications there exist movements in more than one spatial DOF, eventually necessitating more than one damper. Because of this, the damping is required not only in one but in more spatial directions, yet adjustable. In this work, a new design of a spatial 3DOF MR damper is proposed to allow damping in three directions within one damping device. The underlying motivation is to spatially integrate three damping directions in one device to potentially reduce installation space compared to three separate 1DOF dampers. The basic idea of the construction is to use one fluid chamber with several spatially distributed control elements at different positions of the fluid chamber. The control elements are electromagnets, generating the magnetic field in the fluid at different positions so that in total three spatial DOFs can be damped individually. Experiments and investigation are made, where the damper’s behavior are analyzed not only in one single DOF but also in more than one DOF. It is shown, that the damping concept can generate damping in all three spatial DOFs, both individually or together. Moreover, the damping can be generated to be dominant in one specific direction, meanwhile minimum in the other direction orthogonal to it.

Abstract
We investigate the sensitivity of the Laser Interferometer Space Antenna (LISA) to the anisotropies of the Stochastic Gravitational Wave Background (SGWB). We first discuss
the main astrophysical and cosmological sources of SGWB which are characterized by anisotropies in the GW energy density, and we build a Signal-to-Noise estimator to quantify the sensitivity of LISA to different multipoles. We then perform a Fisher matrix analysis of the prospects of detectability of anisotropic features with LISA for individual multipoles, focusing on a SGWB with a power-law frequency profile. We compute the noise angular spectrum taking into account the specific scan strategy of the LISA detector. We analyze the case of the kinematic dipole and quadrupole generated by Doppler boosting an isotropic SGWB. We find that β ΩGW ∼ 2 × 10-11 is required to observe a dipolar signal with LISA. The detector response to the quadrupole has a factor ∼ 103
β relative to that of the dipole. The characterization of the anisotropies, both from a theoretical perspective and from a map-making point of view, allows us to extract information that can be used to understand the origin of the SGWB, and to discriminate among distinct superimposed SGWB sources.

Published: November 2022

Abstract
Lump solutions are one of the most common solutions for nonlinear evolution equations. This study aspires to investigate the generalized Hietarintatype equation. We auspiciously provide multiple M-lump waves. On the other hand, collision phenomena to multiple M-lump waves with soliton wave solutions are also provided. During the collision, the amplitude of the lump will change significantly over the processes, whereas the amplitude of the soliton will just minimally alter. As it is of paramount importance, we use suitable values of parameter to put out the physical features of the reported results through three dimensional and contour graphics. The results presented express physical features of lump and lump interaction phenomena of different kinds of nonlinear physical processes. Further, this study serves to enrich nonlinear dynamics and provide insight into how nonlinear waves propagate.
A laser pistonphone designed for absolute calibration of infrasound sensors from 10 mHz up to 20 Hz

Published: November 2022

Abstract
There has been an increased demand for traceable calibrations at infrasonic frequencies in support of geophysical monitoring applications, an example being the Comprehensive Nuclear-Test-Ban Treaty Organization, which provides global international coverage for a nuclear testing ban, and requires the International Monitoring System. In this paper, a new laser pistonphone design is presented with the objective of establishing primary standards for sound pressure at very low frequencies down to 10 mHz. The piston is a modified accessorized loudspeaker driver whose diameter is equal to the diameter of the front pistonphone cavity. The volume velocity of the piston is measured through a laser interferometer and the current version was designed to have an upper frequency limit of 20 Hz, to overlap with the closed coupler reciprocity method of calibration. Particular attention has been given to the sealing to avoid pressure leakage loss. The dimensions of the front cavity were designed to allow the calibration of a large variety of sensors, including microphones, barometers, manometers and microbarometers. Examples of calibrations for several sensors are presented and also an uncertainty budget for the Brüel & Kjær type 4160 laboratory standard microphones, commonly used for primary calibrations. Finally, the metrological performance of the laser pistonphone is demonstrated by comparing the calibration results with those obtained with alternative methods.

Abstract
In a reversed shear discharge in the Experimental Advanced Superconducting Tokamak (EAST), an internal transport barrier (ITB) was formed. For the first time, the turbulence in the plasma core before and after the formation of the ITB in EAST was investigated by microwave reflectometry. It was found that during the formation of the ITB, the turbulence inside the barrier was not completely suppressed. The density fluctuation level decreased in the early phase of ITB and significantly increased later. It was found that the density fluctuation level increased with the density gradient after the appearance of reversed shear Alfvén eigenmodes (RSAEs). The change in turbulence, measurable by the reflectometer, did not affect the rate of increase in core density. Through the measurement of RSAEs, it was found that the formation of this ITB may be related to the minimum q (q
min). q
min was close to 2.
