Abstract
Waterlogging in soil can limit the availability of nitrogen to plants by promoting denitrification and reducing nitrogen fixation and nitrification. The root-associated microorganisms that determine nitrogen availability at the root-soil interface can be influenced by plant genotype and soil type, which potentially alters the nitrogen uptake capacity of plants in waterlogged soils. In a greenhouse experiment, two soybean genotypes with contrasting capacities to resist waterlogging stress were grown in Udic Argosol and Haplic Alisol soils with and without waterlogging, respectively. Using isotope labeling, high-throughput amplicon sequencing and qPCR, we show that waterlogging negatively affects soybean yield and nitrogen absorption from fertilizer, atmosphere, and soil. These effects were soil-dependent and more pronounced in the waterlogging-sensitive than tolerant genotype. The tolerant genotype harbored more ammonia oxidizers and less nitrous oxide reducers. Anaerobic, nitrogen-fixing, denitrifying and iron-reducing bacteria such as Geobacter/Geomonas, Sphingomonas, Candidatus Koribacter, and Desulfosporosinus were proportionally enriched in association with the tolerant genotype under waterlogging. These changes in the rhizosphere microbiome might ultimately help the plant to improve nitrogen uptake under waterlogged, anoxic conditions. This research contributes to a better understanding of the adaptability of soybean genotypes under waterlogging stress and might help to formulate fertilization strategies that improve nitrogen use efficiency of soybean.

Abstract
Recent innovations in computational structural biology have opened an opportunity to revise our current understanding of the structure and function of clinically important proteins. This study centres on human Oca2 which is located on mature melanosomal membranes. Mutations of Oca2 can result in a form of oculocutanous albinism, which is the most prevalent and visually identifiable form of albinism. Sequence analysis predicts Oca2 to be a member of the SLC13 transporter family, but it has not been classified into any existing SLC families. The modelling of Oca2 with AlphaFold2 and other advanced methods show that, like SLC13 members, it consists of a scaffold and transport domain and displays a pseudo inverted repeat topology that includes re-entrant loops. This finding contradicts the prevailing consensus view of its topology. In addition to the scaffold and transport domains, the presence of a cryptic GOLD domain is revealed that is likely responsible for its trafficking from the endoplasmic reticulum to the Golgi prior to localisation at the melanosomes. The GOLD domain harbours some known glycosylation sites. Analysis of the putative ligand binding site of the model shows the presence of highly conserved key asparagine residues that suggest Oca2 may be a Na+/dicarboxylate symporter. Known critical pathogenic mutations map to structural features present in the repeat regions that form the transport domain. Exploiting the AlphaFold2 multimeric modelling protocol in combination with conventional homology modelling allowed the building of plausible homodimers in both inward- and outward-facing conformations, supporting an elevator-type transport mechanism.
A decentralized control strategy for single‐phase cascaded photovoltaic inverters with MPPT ability
Authors: Luo Zhaoxu , Qin Jianheng , Zhou Feng , Wen Yongxing 
Published: July 2023

AbstractCascaded inverters can improve efficiency and reduce cost, so it is widely used in photovoltaic (PV) grid connected power generation system. However, aging or partial shielding of PV panels will lead to their different maximum power points (MPP). This paper proposes a decentralized control strategy for grid‐connected cascaded PV inverters without any communication, which is capable of integrating PV inverters of different capacities connected in series into the grid, and enable them to achieve maximum power point tracking (MPPT) independently. Compared with the traditional centralized control method relying on real‐time communication, the proposed scheme has advantages of improved reliability and decreased costs. The overall system stability is analysed, and the stability condition is derived as well. The Hardware‐In‐the‐Loop test results show that all the inverters in the cascaded system have their output frequency and voltage phase synchronized autonomously, and achieve MPPT independently even in the presence of variation of light condition. Thus, the feasibility of the proposed method is verified.

Published: July 2023

In this study, we investigated the utilization of alumina (AlOx), formed through the oxidation of thermally evaporated aluminum, as a passivation layer for nanometer-thin indium-tin-oxide (ITO) transistors. The ITO transistors passivated with thermally oxidized AlOx passivation exhibited remarkable electrical properties, with an average field-effect mobility of 241 cm2/Vs, significantly higher than the 40 cm2/Vs observed for devices without the AlOx passivation layer. Moreover, the passivated transistors maintained a high on/off current ratio at 108 level. In addition, the passivated transistors demonstrated improved stability, with a decrease in the threshold voltage (Vth) shift under negative bias stress testing conducted over 3600 seconds. The ITO transistors also displayed better air-ambient stability compared to transistors without the AlOx passivation layer. These results demonstrate the potential application of alumina passivation in nanometer-thin ITO field-effect transistors.
A folded triboelectric sensor for performance evaluation of shock absorbers in automobile
Authors: Sun Bo , Chen Xizeng , Wang Huiqiang 
Published: July 2023

Recently, pressure sensors for vibration monitoring are widely used in mechanical equipment safety monitoring. Here, we proposed a folded triboelectric nanogenerator (TENG) based on polyether Imide/reduced graphene oxide (PEI/rGO) polymer (PR-TENG) with through-hole structure to harvest mechanical energy and monitor the vibration response of automotive shock absorbers. In this design, the polytetrafluoroethylene film andPEI/rGo (PR) polymer film form the triboelectric pairs. When the mechanical frequency reaches 15 Hz, the output performance of the seven-layer PR-TENG device reaches its maximum at 308 V, 55.2 µA, and 198 nC, respectively. When the external load is 5 MΩ, the output power of seven-layer PR-TENG reaches its maximum value of 3 mW. According to the experimental results, when the space size is 30 mm and the number of working layers is 7, the linearity of vibration amplitude monitoring is the best. In addition, by establishing a fitting curve between multilayer PR-TENG and amplitude, the matching relationship between the test amplitude of TENG and the actual amplitude can be observed. The results indicate that the test results are highly consistent with the actual results, indicating that the multilayer PR-TENG matches the vibration response of the shock absorber. This research will promote the development of automotive vibration sensors.

Context Arachidonic acid (AA) is the precursor of prostaglandins, which may play autocrine roles during early embryo development. Aims To test the developmental effects of addition of AA to pre- and post-hatching culture media on in vitro–produced bovine embryos. Methods Pre-hatching effects of AA were tested by culturing bovine zygotes in synthetic oviductal fluid (SOF) supplemented with 100 or 333 μM AA. Post-hatching effects of AA were tested by culturing Day 7 blastocysts in N2B27 supplemented with 5, 10, 20 or 100 μM AA up to Day 12. Key results Pre-hatching development to blastocyst was completely abrogated at 333 μM AA, whereas blastocyst rates and cell numbers were not altered at 100 μM AA. Impaired post-hatching development was observed at 100 μM AA, whereas no effect on survival rates was noted at 5, 10 and 20 μM AA. However, a significant reduction in Day 12 embryo size was observed at 10 and 20 μM AA. Hypoblast migration, epiblast survival and formation of embryonic-disc-like structures were unaffected at 5–10 μM AA. AA exposure downregulated the genes PTGIS, PPARG, LDHA and SCD in Day 12 embryos. Conclusions Pre-hatching embryos are mostly irresponsive to AA, whereas AA was observed to have negative effects during early post-hatching development. Implications AA does not improve in vitro bovine embryo development and is not required up to early post-hatching stages.
Language use, language attitudes, and identity in Aruba
Authors: Kester Ellen-Petra , Buijink Samantha 
Published: July 2023

Abstract
This study investigates the language situation in Aruba, a Caribbean island that is part of the Kingdom of the
Netherlands. The main home language in Aruba is Papiamento, a Spanish/Portuguese lexifier creole, but Dutch was the only official
language for centuries. English and Spanish are also widely used due to immigration, tourism, and the media.
Carroll (2009, 2010, 2015) observes that Papiamento has high vitality, but also signals that speakers think
that the language is under threat due to the increase in the use of English and Spanish. The aim of this study is to examine to
what extent Carroll’s findings may be corroborated by a quantitative survey that accessed the views of a large group of people
(809) from all over the island. The results indicate that Papiamento is the most frequently cited language regardless of
backgrounds. People hold positive attitudes toward Papiamento and Aruban identity. Hence, our findings corroborate Carroll’s
hypothesis that sentiments of language threat are mostly based in perception rather than in actual language use and attitudes.
Orthography, ideology and the codification of Mauritian Creole
Authors: Auckle Tejshree 
Published: July 2023

Abstract
This paper examines the choices made at the levels of Ausbau (‘language by development’, Kloss 1967: 29–30) and Abstand (‘language by distance’, ibid) during the codification phase of Mauritian
Creole. Using the document Lortograf Kreol Morisien (Ministry of Education
and Human Resources 2011) as its focal point, it studies the co-association between Ausbau and Abstand and connects the
choices made to a broader ideological framework which sets out to ‘promot[e] our country’s language’ (Hookoomsing 2011: 9). It explores the implication of adopting a linguistic form which a user can
‘intimately connect with loved ones, community and personal identity’ (Delpit 2006: 95)
while simultaneously providing it with the stature traditionally enjoyed by the lexifier. In the final instance it views the
decreasing Abstand of Mauritian Creole as a form of prestige planning (Haarmann 1986)
carried out with the possible intention of enhancing its public image.
A mental spaces analysis of religious identity discourse
Authors: Mueller Charles M. , Richardson Peter , Pihlaja Stephen 
Published: July 2023

Abstract
Religious identity is often viewed as a relatively stable construct, reflecting an individual’s personal worldview. However, individuals living within modern multi-cultural societies often must engage in extensive reflection to orient themselves to faith traditions in ways that are coherent and personally relevant. Although some work has examined the connection between narratives of religious experience, identity and cognition (cf. Richardson, 2012; Richardson & Nagashima, 2018; Richardson & Mueller, 2019), the relationship between thinking and speaking about this identity is still a developing area of enquiry, with important consequences for how religious faith and practice are understood. This article presents a detailed analysis of an interview with a UK-based Jewish woman based on the mental spaces (Fauconnier, 1994) and conceptual blending (Fauconnier & Turner, 2002) frameworks. The analysis shows how mental spaces and the relationship between elements within those spaces emerge over the course of a discourse event so as to constitute a personal account of religious identity. The concluding section furthermore discusses how within- and across-space contrast links are utilized, along with general processes of compression and decompression, to develop a blend that dynamically expresses the interviewee’s religious identity as an integrated and coherent position lying between competing attractor states.
An experimental study for thermal sensing applications of PP and PN heterojunctions fabricated in the same architecture and under the same conditions
Authors: Gumus Ilknur , Aydogan Sakir 
Published: July 2023

Abstract
In this research, Ni/p-GO@Fe3O4/p-Si (P–P) and Ni/ p-GO@Fe3O4/n-Si (P–N) heterojunctions (HJs) were constructed under the same conditions. Current–voltage (I–V) measurements of devices over a wide temperature range were investigated. Thermionic emission theory was used to evaluate the temperature-dependent I–V characteristics. The ideality factor (n), barrier height (Φ), rectification ratio (RR) and turn-on voltage (V
0), which are the main HJ parameters of the HJs, were determined as a function of temperature and it was seen that all parameters were dependent on temperature. The n, RR, and V
0 values for both devices decreased with increasing temperature, while Φ increased. This was attributed to the inhomogeneity between p-GO@Fe3O4 and Si. The thermal sensitivity (S) and activation energy of both devices were calculated and it was seen that S decreased linearly with increasing current. Furthermore, the highest sensitivity and the lowest activation energy values were determined as 1.35 mV K−1 and 0.79 eV, respectively for P–P HJ. These values were calculated as 0.97 mV K−1 and 0.66 eV for P–N HJ, respectively.
Stabilization despite pervasive strong cross-degeneracies in a nonlinear diffusion model for migration–consumption interaction
Authors: Winkler Michael 
Published: July 2023

AbstractA no-flux initial-boundary value problem forut=Δ(uϕ(v)),vt=Δv−uv,(⋆)is considered in smoothly bounded subdomains ofRnwithn⩾1and suitably regular initial data, whereφis assumed to reflect algebraic type cross-degeneracies by sharing essential features with0⩽ξ↦ξαfor someα⩾1. Based on the discovery of a gradient structure acting at regularity levels mild enough to be consistent with degeneracy-driven limitations of smoothness information, in this general setting it is shown that with some measurable limit profileu∞and some null setN⋆⊂(0,∞), a corresponding global generalized solution, known to exist according to recent literature, satisfiesρ(u(⋅,t))⇀⋆ρ(u∞)in L∞(Ω) and v(⋅,t)→0in Lp(Ω)for all p⩾1as(0,∞)∖N⋆∋t→∞, whereρ(ξ):=ξ2(ξ+1)2,ξ⩾0. In the particular case when eithern⩽2andα⩾1is arbitrary, orn⩾1andα∈[1,2], additional quantitative information on the deviation of trajectories from the initial data is derived. This is found to imply a lower estimate for the spatial oscillation of the respective first components throughout evolution, and moreover this is seen to entail that each of the uncountably many steady states(u⋆,0)of (⋆) is stable with respect to a suitably chosen norm topology.
Probing the origin of primordial black holes through novel gravitational wave spectrum
Authors: Banerjee Indra Kumar , Dey Ujjal Kumar 
Published: July 2023

AbstractIn this article we investigate the cumulative stochastic gravitational wave spectra as a tool to gain insight on the creation mechanism of primordial black holes. We consider gravitational waves from the production mechanism of primordial black holes and from the gravitational interactions of those primordial black holes among themselves and other astrophysical black holes. We specifically focus on asynchronous bubble nucleation during a first order phase transition as the creation mechanism. We have used two benchmark phase transitions through which the primordial black holes and the primary gravitational wave spectra have been generated. We have considered binary systems and close hyperbolic interactions of primordial black holes with other primordial and astrophysical black holes as the source of the secondary part of the spectra. We have shown that this unique cumulative spectra have features which directly and indirectly depend on the specifics of the production mechanism.
Ultra-peripheral collisions of charged hadrons in extensive air showers
Authors: Masip Manuel , Rosario Ivan , Sciutto Sergio J. 
Published: July 2023

Abstract
We discuss the electromagnetic collisions of high energy protons, pions and kaons with
atmospheric nuclei. In particular, we use the equivalent photon approximation to estimate (i) the diffractive collisions where the projectile scatters inelastically off a nucleus, and
(ii) the usual radiative processes (bremsstrahlung, pair production and photonuclear
interactions) of these charged hadrons in the air. We then include the processes in the simulator
AIRES and study how they affect the longitudinal development of extensive air showers. For
109-11 GeV proton primaries we find that they introduce a very small reduction (below 1%) in
the average value of both X
max and ΔX
max. At a given shower age (relative slant depth from
X
max), these electromagnetic processes slightly increase the number of charged particles at the
shower maximum and reduce the number of muons when it is old, decreasing by 1% the
muon-to-(γ + e) near the ground level.
Constraints on the non-minimally coupled Witten-O'Raifeartaigh inflation
Authors: dos Santos F.B.M. , Silva R. , Alcaniz J.S. 
Published: July 2023

Abstract
We investigate the impact of a non-minimal coupling of the scalar field with gravity in
inflationary models, where a small coupling is allowed. As a concrete example, we consider the
Witten-O'Raifeartaigh model, where, in line with other models, the presence of a coupling strength
ξ can recover concordance of the inflationary parameters with cosmic microwave background (CMB) constraints, provided by the Planck collaboration. We go beyond the slow-roll regime and
investigate the impact in the description of CMB anisotropies by performing a statistical analysis
of the model with the most recent Planck + Baryon Acoustic Oscillations (BAO) data to seek for any
indication of a non-zero coupling by data within the model. We find that not only the presence of
a non-minimal coupling is seen, but the model has a slight statistical preference when compared
with the standard ΛCDM one. We also discuss the results on the minimally-coupled model,
which in general, favours the simple setting where the associated mass scale is equal to the
reduced Planck mass Mp
while being, in general, disfavored concerning the standard model.
Kinetic field theory: generic effects of alternative gravity theories on non-linear cosmic density-fluctuations
Authors: Oestreicher A. , Capuano L. , Matarrese S. , Heisenberg L. , Bartelmann M. 
Published: July 2023

Abstract
Non-linear cosmic structures contain valuable information on the expansion history of the background space-time, the nature of dark matter, and the gravitational interaction. The recently developed kinetic field theory of cosmic structure formation (KFT) allows to accurately calculate the non-linear power spectrum of cosmic density fluctuations up to wave numbers of k ≲ 10 h Mpc-1 at redshift zero. Cosmology and gravity enter this calculation via two functions, viz. the background expansion function and possibly a time-dependent modification of the gravitational coupling strength.
The success of the cosmological standard model based on general relativity suggests that cosmological models in generalized theories of gravity should have observable effects differing only weakly from those in standard cosmology. Based on this assumption, we derive the functional, first-order Taylor expansion of the non-linear power spectrum of cosmic density fluctuations obtained from the mean-field approximation in KFT in terms of the expansion function and the gravitational coupling strength. This allows us to study non-linear power spectra expected in large classes of generalized gravity theories. To give one example, we apply our formalism to generalized Proca theories.

Abstract
The 100 m long X-ray test facility (100XF for clarity) in Institute of High Energy Physics of CAS has been playing an increasingly important role in the X-ray astronomy field in China. 100XF has been contributing to the missions under development, such as the Einstein Probe mission. The facility has also been providing support to R&D of focusing X-ray optics in China that will enable future X-ray telescopes to be realized, such as the enhanced X-ray Timing and Polarization (eXTP) mission. A pnCCD-based camera has been employed at 100XF to rapidly measure the performance of the X-ray optics. In this work, we study the performance of the camera and its spectral and imaging applications at 100XF. The camera system can provide a high frame readout rate, with a low readout noise <3 e−. It is sensitive to X-ray photons in the 3–10 keV energy band with a high quantum efficiency exceeding 90%. Actually, the low threshold of detection energy range can reach down to 0.2 keV. The energy resolution can reach 145.2 eV for single events and 154.8 eV for all valid events (including single events and split events) at 6.4 keV. The camera also exhibits excellent imaging capability in both the full frame mode and the windowing mode, with a readout rate of up to 1000 Hz. Finally, a prototype of a focusing X-ray mirror shell of eXTP was smoothly measured with this camera. The obtained on-axis point-spread function and half-power diameter are consistent with expectations. It is proven that the camera can improve the capability of 100XF in characterizing the X-ray optics. This camera will be very useful for performing on-ground calibrations for future X-ray telescope missions.
Structural design and mechanical performance verification of a mobile piler with a double-scissor fork

Published: July 2023

AbstractThe traditional piler structure is column type. The stacker of this structure needs the same height as the top of the warehouse. At present, there is no good solution for highly inconsistent special-shaped warehouses. This paper proposes a piler based on the requirement of variable height of the piler based on a double shear fork mechanism. The double shear difference mechanism drives the lifting and lowering of the piler. Since there is no need to arrange rails on the top of the warehouse, they can be used in warehouses with different heights. Especially for warehouses with a height of less than 3 m, this new structure of piler has broad application space and application prospects. Finally, according to the actual working force of the piler, the mechanical model is established and verified by FEM. It is proved that the stacking machine with this structure has good mechanical properties.
