description: For most of the state-of-the-art speech enhancement techniques, a spectrogram is usually preferred than the respective time-domain raw data since it reveals more compact presentation together with conspicuous temporal information over a long time span. However, the short-time Fourier transform (STFT) that creates the spectrogram in general distorts the original signal and thereby limits the capability of the associated speech enhancement techniques. In this study, we propose a novel speech enhancement method that adopts the algorithms of discrete wavelet packet transform (DWPT) and nonnegative matrix factorization (NMF) in order to conquer the aforementioned limitation. In brief, the DWPT is first applied to split a time-domain speech signal into a series of subband signals without introducing any distortion. Then we exploit NMF to highlight the speech component for each subband. Finally, the enhanced subband signals are joined together via the inverse DWPT to reconstruct a noise-reduced signal in time domain. We evaluate the proposed DWPT-NMF based speech enhancement method on the MHINT task. Experimental results show that this new method behaves very well in prompting speech quality and intelligibility and it outperforms the convnenitional STFT-NMF based method.

description: The aim of deliverable D5.2 of the Eklipse project (EU Horizon 2020, grant agreement no.690474) was to further improve the ‘network of networks’ model of Eklipse and to engage new actors within it. The tree key questions, answered in the report, included the following ones: 1) how existing networks function; 2) what kind of knowledge and capacity gaps exist and which conditions are required to foster more effective interactions at the science-policy-society interface, and 3) what kind of expectations do existing networks have towards Eklipse. Qualitative and quantitative data were collected and critically analysed in two iterative rounds to shed light on key aspects of networking and to improve the Eklipse Network of Networks (NoN). Several capacity and knowledge gaps were revealed by the study, which hinder effective participation in science-policy-society interactions and could be improved by targeted capacity building actions. These included knowledge gaps with thematic foci (e.g. uncertainty, ES disservices, assessment) and concerning the way how science can link up with the policy cycle; capacity gaps in communication, networking and knowledge generation/sharing, and capacity gaps in networks’ administrative functioning (e.g. fund raising, human resources etc.).

description: The magnetization, magnetic susceptibility, and specific heat of the single crystalline sample SmRh$_2$Zn$_{20}$ were measured. The valence of Sm ions in SmRh$_2$Zn$_{20}$ was found to be trivalent. No evidence of valence fluctuations was detected. SmRh$_2$Zn$_{20}$ is an antiferromagnet with $T_{\rm N}=$ 2.46 K. The observed $C(T,H)$ curves showed that $T_{\rm N}$ splits into two in the external field $H$ along the [001] and [101]directions. On the other hand, $T_{\rm N}$ in $H$ along the [111] direction did not split, decreasing to 2.20 K at $H=7$ T. At 2 K, the magnetization $M_{111}$ in $H$ along the [111] direction increased linearly with increasing field, while $M_{001}$ and $M_{101}$ deviated upward slightly from the linear dependence. We analyzed the observed magnetic and thermal properties of SmRh$_2$Zn$_{20}$ taking into account the crystalline-electric-field effect, the Zeeman energy, and the exchange interaction. The theoretical calculation well reproduced the experimental $χ(T)$, $M(H)$, $C(T,H)$ and $T_{\rm N}(H)$. The sublattice magnetic moments are expected to be along the $\langle 111\rangle$ direction below $T_{\rm N}$ at $H=0$ T. Variations of the magnetic structures induced by the external magnetic fields in a narrow temperature region around $T_{\rm N}$ are inferred on the basis of theoretical calculations.

description: Developments in PV technologies may lead to cheaper PV micro-generation systems at the likely
expense of life expectancy and efficiency. With decreasing costs of PV technologies, the cost of electricity from PV
systems will move towards grid parity prices. At the same time electric power systems are evolving into smart grids.
This paper presents a methodology for optimal integration of grid-connected photovoltaic (PV) systems using
emerging PV technologies. Under the proposed methodology, PV systems are modeled as active and pro-active
participants within the smart electricity grid from the design stage through to system life cycle performance. This is in
contrast to the current situation where micro-generators are treated as passive participants in the grid. A mixed
integer programming model has been developed to optimize the energy flow management in a future PV system with
or without energy storage. The objectives are to minimise the annual energy cost and maximise the PV contribution
to the on-site load. Using this multi-objective approach, an investigation is conducted on the characteristics of
emerging PV technologies that may need to be met to penetrate the market without subsidies or direct monetary
support schemes.

description: Tab ribbons are used to conduct current from Si thin-film solar cells to the junction box, where a
reliable connection with low contact resistance is required. Ultrasonic bonding is a room-temperature process that
can create stronger and more reliable bonds with lower contact resistance at a lower consumable cost. Two types of
ribbons (Al ribbon and Al-clad Cu ribbon) with different sizes were ultrasonically bonded on four different Si thinfilm
solar panels. The cell structure, metallization layer, and surface conditions and their influence on the ultrasonic
bonds were investigated. The process parameters and several bondtool configurations were systematically studied.
Bond quality was evaluated mechanically by a 90° bond peel test and electrically by measuring contact resistance.
Potential cell damage was inspected by microscope and monitored by measuring the open circuit voltage (Voc) and
short circuit current (Isc) of the panel. Robust, reliable bonds were demonstrated by 800 temperature cycles, 1000
hours damp heat, and accelerated lifetime tests. A 16-month accelerated lifetime test showed that the modules with
ultrasonically-bonded tab ribbons passed four combined cycles, while four other commercial thin-film modules failed
within 1.5 combined cycles.

description: The analysis of high-precision $π^{\pm}p \to π^{\pm}p$ cross section data from the EPECUR Collaboration based on the multichannel $K$-matrix approach is presented.The sharp structures seen in these data are studied in terms of both opening thresholds and new resonance contributions. Some prominent features are found to be due to the opening $KΣ$ channel. However, a complete description of the data is improved with the addition of two narrow resonant structures at $W\sim 1.686$ and $W\sim 1.720$ GeV. These structures are interpreted as manifestations of $S_{11}$ and $P_{11}$ resonances. The underlying nature of the observed phenomena is discussed.

currently available instantaneous values of the irradiance, different results are achieved.

description: This was presented as a poster at the 2023 AGU meeting in San Franciso, CA.

Many aspects of Open Science depend on a robust community of people who manage scientific data and create and curate analysis software. Therefore, we initiated the DASH meeting to provide a venue for increased communication and collaboration among informatics and data science practitioners throughout Heliophysics and related Geosciences areas. DASH 2023 will have been held in early October, covering high-level themes such as cloud computing, machine learning, and Python development, as well as more specific topics including data processing pipelines, data service interfaces, and solar coronal analysis. Note that DASH 2023 is held adjacent to the yearly gathering for the International Heliophysics Data Environment Alliance (IHDEA), reflecting the intent that both DASH and IHDEA be inclusive across national borders. We are also emphasizing early career participation, and a less formal meeting structure with plenty of time for discussion. We will provide a summary of the DASH meeting, describe highlights and outcomes, and discuss plans for future meetings.

description: Global population has grown from approximately one billion a hundred years ago to eight billion in 2022. To feed this rapidly expanding population has required sustained technological advances in agricultural production and food storage, transportation and processing. This technological progress is fostered by the application of science and engineering to mechanization, chemistry and genetics. While not everyone is well fed, most are. Feeding the additional two billion people expected by 2050 will require continued technological advances. Some countries, however, are in the process of eschewing the use of modern agricultural technology to return agricultural production to pre-modern methods. They do so at their peril and, in some cases, threaten the food security of their populations. The major mandated changes in production methods also have the potential to create barriers to international trade – again negatively impacting on food security. This paper reports on the results of three such experiments in Sri Lanka, Mexico and the European Union. The conclusion is that policy makers should take more care when making radical changes in agricultural policy pertaining to production methods.

description: We demonstrate an efficient core-shell GaAs/AlGaAs nanowire photodetector operating at room temperature. The design of this nanoscale detector is based on a type-I heterostructure combined with a metal-semiconductor-metal (MSM) radial architecture, in which built-in electric fields at the semiconductor heterointerface and at the metal/semiconductor Schottky contact promote photogenerated charge separation, enhancing photosensitivity. The spectral photoconductive response shows that the nanowire supports resonant optical modes in the near-infrared region, which lead to large photocurrent density in agreement with the predictions of electromagnetic and transport computational models. The single nanowire photodetector shows remarkable peak photoresponsivity of 0.57 A/W, comparable to large-area planar GaAs photodetectors on the market, and a high detectivity of 7.2 10^10 cm\sqrt{Hz}/W at λ=855 nm. This is promising for the design of a new generation of highly sensitive single nanowire photodetectors by controlling optical mode confinement, bandgap, density of states, and electrode engineering.

description: We have carried out semi-empirical modelling of amorphous silicon/microcrystalline silicon thin-film solar
cells in tandem optical configuration, under series (two-terminal) and independent (four-terminal) electrical connections,
versus top-cell layer thickness, for initial and degraded states of the amorphous silicon sub-cell. This was done by scaling
typical experimental J-V characteristics for each sub-cell along the current axis by the short-circuit current densities
calculated under AM1.5 illumination, and then solving under equal-current (two-terminal) and independent-current
(four-terminal) maximum-power conditions. The bottom-cell remained unchanged throughout. No intermediate tunnel
junction or contacts, or optical gains or losses specific to either connection were included. In the initial state, an increase
in maximum efficiency from 10.0% (two-terminal) to 10.8% (four-terminal) is indicated. In the degraded state, the
figures are 8.5% and 9.8% respectively. The optimum degraded top-cell in four-terminal connection is 150 nm thick.

description: Proton spin is investigated in chiral effective field theory through an examination of the singlet axial charge, $a_0$, and the two non-singlet axial charges, $a_3$ and $a_8$. Finite-range regularization is considered as it provides an effective model for estimating the role of disconnected sea-quark loop contributions to baryon observables. Baryon octet and decuplet intermediate states are included to enrich the spin and flavour structure of the nucleon, redistributing spin under the constraints of chiral symmetry. In this context, the proton spin puzzle is well understood with the calculation describing all three of the axial charges reasonably well. The strange quark contribution to the proton spin is negative with magnitude 0.01. With appropriate $Q^2$ evolution, we find the singlet axial charge at the experimental scale to be ${\hat a}_0 = 0.31^{+0.04}_{-0.05}$, consistent with the range of current experimental values.

description: In this study the influence of sulfuric acid on the frequently-used HF-HNO3-H2O silicon etching
system is investigated. Silicon etching rates are strongly affected by sulfuric acid. Raman and UV/Vis spectroscopy
turned out to be very useful for etch bath analytics. Nitrous acid HNO2 and nitrosyl ions NO+ were identified as
intermediates in HF-HNO3-based etching mixtures. Laser scanning microscopy was performed to characterize etched
silicon surfaces. Etched surface morphologies depend on sulfuric acid concentrations. Nitronium ion containing
mixtures generate rough and porous surfaces.

description: Background: The radial forearm flap remains the gold standard in phalloplasty in gender-affirming surgery due to its versatility and functional outcome, but the significant donor site morbidity and its impact on daily functioning and aesthetic perception remains understudied. This study provides valuable insights into the mid-term functional and aesthetic outcomes of the forearm in transgender individuals following radial forearm flap phalloplasty using widespread instruments for assessment scoring systems and for the evaluation of postoperative wound healing of surgical interventions in general. Methods: Between January 2013 and March 2018, a total of 47 patients underwent radial phalloplasty at AGAPLESION Markus Hospital, and 20 consented to participate in this cross-sectional, retrospective study evaluating functional and aesthetic outcomes post-radial forearm flap phalloplasty using standardized questionnaires (DASH, POSAS, and SBSES). A univariate median regression of each score was performed to determine the associations with selected variables, and correlation analyses between scores was performed using a nonparametric Spearman rank correlation. Results: Among the 20 participants, the median Quick DASH, DASH functionality, DASH sport and music, and DASH work scores indicated minimal to no functional impairment. Scar evaluations using the PSAS, OSAS, and SBSES scales showed overall patient satisfaction with minimal concerns regarding pigmentation and scar texture. Notably, an increase of 0.27 cm2 in wound surface area added one point to the DASH sport and music score (p = 0.037). Statistical analysis also demonstrated a significant correlation between functional and aesthetic assessment scores. Conclusions: The radial forearm phalloplasty donor site, evaluated by the PSAS, OSAS, and SBSES scales, leads to minimal or no functional impairment; however, the worsening of the DASH sport and music score with increasing wound surface reflects a direct relation between wound size and functional impairment.

description: Climate change is causing warmer winter and spring periods with increased frequency of chilling and frost damage on crop plants. Psychrotolerant plant-associated bacteria could improve plant tolerance to cold stress. This work aims to identify psychrotolerant bacteria associated with cold-adapted plants and to understand mechanisms responsible for cold tolerance in crops. The bacterial community structure associated with alpine and Arctic plants was characterized by metataxonomic analyses and taxa associated with cold tolerance were highlighted. Psychrotolerant bacterial endophytes collected from cold-adapted plants improved the shoot growth of tomato seedlings under chilling stress and limited frost damage on apple and strawberry leaves. Bacterium-inoculated plants showed enhanced metabolic changes in response to chilling exposure and recovery, suggesting intimate interactions between psychrotolerant bacteria and the plant host.

description: The amount of impurities and contaminations in the feedstock material and in the crystallized silicon
ingots is one major source of defects and electrical losses in the later processed solar cells. Therefore, a reliable
analysis of trace elements in silicon is of fundamental importance for the understanding of material properties and
quality control. We demonstrate here the power of two analytical techniques for the determination of trace elements
in solar silicon: ICP-MS and ToF-SIMS which are among the few techniques that achieve sufficiently low detection
limits and which may complement each other due to their specific performance. We show examples of the
quantitative chemical analysis of boron, phosphorus and iron in different solar silicon as well as the enrichment of
metals and alkali metals in Si3N4 precipitates.

description: Tunable photonic elements at the surface of an optical fiber with piezoelectric core are proposed and analyzed theoretically. These elements are based on whispering gallery modes whose propagation along the fiber is fully controlled by nanoscale variation of the effective fiber radius, which can be tuned by means of a piezoelectric actuator embedded into the core. The developed theory allows one to express the introduced effective radius variation through the shape of the actuator and the voltage applied to it. In particular, the design of a miniature tunable optical delay line and a miniature tunable dispersion compensator is presented. The potential application of the suggested model to the design of a miniature optical buffer is discussed.

description: Electric network calculation of currents and voltages in an arbitrary configuration with multiple
generation and load nodes is a time consuming task. The standard method for a network calculation usually involves
matrix iteration, which tends to be very slow as the number of nodes gets large. By approximating, a new method can
be formulated to increase the speed of voltage evaluation considerably. This enables easier evaluation of problems
related voltage when introducing large schemes of distributed energy generation. The method can be used e.g. to find
the optimal place and the maximal amount of electricity generation with given tolerance of overvoltage in a
distribution network.

description: Brute force matching of binary image feature descriptors is conventionally performed using the Hamming distance. This paper assesses the use of alternative metrics in order to see whether they can produce feature correspondences that yield more accurate homography matrices. Two statistical tests, namely ANOVA (Analysis of Variance) and McNemar's test were employed for evaluation. Results show that Jackard-Needham and Dice metrics can display better performance for some descriptors. Yet, these performance differences were not found to be statistically significant.

description: This study covers the design of innovative product concepts based on a combination of PV and LED
technology. The products were developed in a project that took place in 2008 and 2009 during a cooperation of the
University of Twente with Philips Lighting. It is shown that surprisingly unpredictable - yet technically feasible – PV
powered LED products can be designed by carefully selected industrial design methods and an open view towards
potential applications. In this scope innovation is not just a matter of implementing advanced technology in existing
products, but particularly a matter of sensing new opportunities which are created by the combination of new
technologies such as LEDs and PV technology. The PV powered LED product concepts range from small products,
like watches, remote controls and other electronic handhelds, to large-sized products such as tents. In this paper it is
shown how the concepts have been developed and they will be visualized by high key renderings. Also attention will
be paid to the prototyping a few product concepts to evaluate their functional requirements.

description: One-way quantum deficit and quantum discord are two important measures of quantum correlations. We revisit the relationship between them in two-qubit systems. We investigate the conditions that both one-way quantum deficit and quantum discord have the same optimal measurement ensembles, and demonstrate that one-way quantum deficit can be derived from the quantum discord for a class of X states. Moreover, we give an explicit relation between one-way quantum deficit and entanglement of formation. We show that under phase damping channel both one-way quantum deficit and quantum discord evolve exactly in the same way for four parameters X states. Some examples are presented in details.

description: Inertial sensors based on cold atom interferometry exhibit many interesting features for applications related to inertial navigation, particularly in terms of sensitivity and long-term stability. However, at present the typical atom interferometer is still very much an experiment---consisting of a bulky, static apparatus with a limited dynamic range and high sensitivity to environmental effects. To be compliant with mobile applications further development is needed. In this work, we present a compact and mobile experiment, which we recently used to achieve the first inertial measurements with an atomic accelerometer onboard an aircraft. By integrating classical inertial sensors into our apparatus, we are able to operate the atomic sensor well beyond its standard operating range, corresponding to half of an interference fringe. We report atom-based acceleration measurements along both the horizontal and vertical axes of the aircraft with one-shot sensitivities of $2.3 \times 10^{-4}\,g$ over a range of $\sim 0.1\,g$. The same technology can be used to develop cold-atom gyroscopes, which could surpass the best optical gyroscopes in terms of long-term sensitivity. Our apparatus was also designed to study multi-axis atom interferometry with the goal of realizing a full inertial measurement unit comprised of the three axes of acceleration and rotation. Finally, we present a compact and tunable laser system, which constitutes an essential part of any cold-atom-based sensor. The architecture of the laser is based on phase modulating a single fiber-optic laser diode, and can be tuned over a range of 1 GHz in less than 200 $μ$s.

description: In the braneworld scenario the zero mode gravitons are trapped on a brane due to non-linear warping effect, so that gravitational waves can reflect from the brane walls. If the reflected waves form an interference pattern on the brane then it can be detected on existing detectors due to spatial variations of intensity in the pattern. As an example we interpret the LIGO event GW150914 as a manifestation of such interference pattern produced by the burst gravitational waves, emitted by a powerful source inside or outside the brane and reflected from the brane walls.

description: We analyse the performance of two quantum-state-transfer Hamiltonians in the presence of diagonal and off-diagonal disorder, and in terms of different measures. The first Hamiltonian pertains to a fully-engineered chain and the second to a chain with modified boundary couplings. The task is to find which Hamiltonian is the most robust to given levels of disorder and irrespective of the input state. In this respect, it is shown that the performance of the two protocols are approximately equivalent.

description: To a large class of graphs of groups we associate a C*-algebra universal for generators and relations. We show that this C*-algebra is stably isomorphic to the crossed product induced from the action of the fundamental group of the graph of groups on the boundary of its Bass-Serre tree. We characterise when this action is minimal, and find a sufficient condition under which it is locally contractive. In the case of generalised Baumslag-Solitar graphs of groups (graphs of groups in which every group is infinite cyclic) we also characterise topological freeness of this action. We are then able to establish a dichotomy for simple C*-algebras associated to generalised Baumslag-Solitar graphs of groups: they are either a Kirchberg algebra, or a stable Bunce-Deddens algebra.

A Hybrid Transmission Grid Architecture Enabling Efficient Optimal Power Flow

description: The recent rise of electricity generation based on renewable energy sources increases the demand for transmission capacity. Capacity expansion via the upgrade of transmission line capacity, e.g., by conversion to a high-voltage direct current (HVDC) line, is an attractive option. In this paper, it is shown that if the upgrade to HVDC is applied systematically to selected transmission lines across the grid, a hybrid architecture is obtained that enables an efficient and globally optimal solution of the optimal power flow (OPF) problem. More precisely, for conventional meshed AC transmission grids the OPF problem is nonconvex and in general NP-hard, rendering it hard to solve. We prove that after the upgrade to the proposed hybrid architecture, the same mesh topology facilitates an exact convex relaxation of the OPF problem, enabling its globally optimal solution with efficient polynomial time algorithms. This OPF method is then employed in simulations, which demonstrate that the hybrid architecture can increase the effective transmission capacity and substantially reduce the generation costs, even compared to the AC grid with optimal transmission switching.

description: In classical amorphous/crystalline silicon (a-Si:H/c-Si) heterojunction solar cells, very low interface
defect densities and, thus, high open circuit voltages above Voc = 700 mV, can be achieved. However, the external
quantum efficiency EQE at short wavelengths and thereby the short circuit current density jsc are decreased by
parasitic absorption in the low band-gap a-Si:H layer, especially if stacks of doped and undoped a-Si:H are used.
Implementation of a SiO2 tunnel oxide layer instead of the undoped a-Si:H at the interface is proposed to decrease
this absorption losses. In this contribution we demonstrate that to this end, high-quality ultrathin SiO2 tunnel layers
(< 2 nm) with both chemically abrupt interfaces and low densities of interface states can be produced on c-Si by
plasma oxidation with thermalized atomic oxygen at low substrate temperatures of 200 °C. Efficient reduction of
densities of electronic defect states is achieved by proper passivation with thermalized atomic hydrogen and wetchemical
wafer pre-treatment.
The Controlled Natural Language of Randall Munroe's Thing Explainer

description: It is rare that texts or entire books written in a Controlled Natural Language (CNL) become very popular, but exactly this has happened with a book that has been published last year. Randall Munroe's Thing Explainer uses only the 1'000 most often used words of the English language together with drawn pictures to explain complicated things such as nuclear reactors, jet engines, the solar system, and dishwashers. This restricted language is a very interesting new case for the CNL community. I describe here its place in the context of existing approaches on Controlled Natural Languages, and I provide a first analysis from a scientific perspective, covering the word production rules and word distributions.
Resonantly Enhanced Multiphoton Ionization under XUV FEL radiation: A case study of the role of harmonics

description: We provide a detailed quantitative study of the possible role of a small admixture of harmonics on resonant two-photon ionization. The motivation comes from the occasional presence of 2nd and 3rd harmonics in FEL radiation. We obtain the dependence of ionic yields on the intensity of the fundamental, the percentage of 2nd harmonic and the detuning of the fundamental from resonance. Having examined the cases of one and two intermediate resonances, we arrive at results of general validity and global behavior, showing that even a small amount of harmonic may seem deceptively innocuous.

The role of central bank regulations in enhancing Islamic bank performance in Egypt

Subjects: Banking, finance and investment not elsewhere classified

description: One of the key success elements of economic development is a well-established, banking system. This sector is often considered for mobilising savings as credit or investment tools. In addition, the banking system plays a vital role in increasing investments to serve the financial resources essential for developmental needs (Etab, 2016). However, continual financial crises have resulted in troubles in many conventional banks all over the world. By contrast, the Islamic banks (IBs) were safeguarded against these crises (Johnes et al., 2014). In fact, Islamic banking broadened its requests to more investors other than just traditional Muslims ones. Recently, more than 300 Islamic financial institutions were established in 70 countries across the world (Johnes et al., 2014).

description: Three-dimensional topological Dirac semimetals have hitherto stimulated unprecedented research interests as a new class of quantum materials. Breaking certain types of symmetries has been proposed to enable the manipulation of Dirac fermions; and that was soon realized by external modulations such as magnetic fields. However, an intrinsic manipulation of Dirac states, which is more efficient and desirable, remains a significant challenge. Here, we report a systematic study of quasi-particle dynamics and band evolution in Cd3As2 thin films with controlled Chromium (Cr) doping by both magneto-infrared spectroscopy and electrical transport. For the first time, we observe square-root-B relation of inter-Landau-level resonance in undoped Cd3As2 Dirac semimetal, an important signature of ultra-relativistic Dirac state inaccessible in previous optical experiments. A crossover from quantum to quasi-classical behavior makes it possible to directly probe the mass of Dirac fermions. Importantly, Cr doping allows for a Dirac mass acquisition and topological phase transition enabling a desired dynamic control of Dirac fermions. Corroborating with the density-functional theory calculations, we show that the mass generation is essentially driven by explicit C4 rotation symmetry breaking and the resultant Dirac gap engineering through Cr substitution for Cd atoms. The manipulation of the system symmetry and Dirac mass in Cd3As2 thin films provides a tuning knob to explore the exotic states stemming from the parent phase of Dirac semimetals.
The role of phase dynamics in a stochastic model of a passively advected scalar

description: Collective synchronous motion of the phases is introduced in a model for the stochastic passive advection-diffusion of a scalar with external forcing. The model for the phase coupling dynamics follows the well known Kuramoto model paradigm of limit-cycle oscillators. The natural frequencies in the Kuramoto model are assumed to obey a given scale dependence through a dispersion relation of the drift-wave form $-β\frac{k}{1+k^2}$, where $β$ is a constant representing the typical strength of the gradient. The present aim is to study the importance of collective phase dynamics on the characteristic time evolution of the fluctuation energy and the formation of coherent structures. Our results show that the assumption of a fully stochastic phase state of turbulence is more relevant for high values of $β$, where we find that the energy spectrum follows a $k^{-7/2}$ scaling. Whereas for lower $β$ there is a significant difference between a-synchronised and synchronised phase states, and one could expect the formation of coherent modulations in the latter case.
