Context Cows are often subjected to different environmental and handling conditions for research purposes, and it is important to understand potential behavioural changes, as they may influence research outcomes. Aim To investigate how a transfer from a group housing system to individual pens affected dairy cow behaviour. Methods Lactating dairy cows (n = 24), housed in an open-sided barn, were transferred to individual pens for 10 weeks. For another experiment’s purposes, cows were assigned to a control or an experimental diet. Measurements were taken before transfer (pre), after transfer to the individual pens (early), in the individual pens (late transfer) and on return to the barn (post transfer). Cows’ behaviour was assessed every 10 min for 8 h per day, and whether cows were eating, ruminating or idling was recorded. Occurrences of social interactions were recorded continuously during the last 60-s of every 10-min observation. Lying time was recorded using dataloggers. Locomotory ability assessment and daily milk yields were also recorded. Key results Ruminating and eating time was not affected by diet type, but decreased after transfer to the individual pens. Only eating time returned to pre transfer values at early transfer. Time that control cows spent idling increased in individual pens, whereas the experimental diet cows spent more time idling in the early transfer phase. Social interactions occurred more often during late and post transfer phases. Cow locomotory ability was not affected by the transfer or by type of diet, but total lying time increased from pre to post transfer, the number of lying bouts decreased from late to post transfer phases, and lying bout duration increased as the experimental period progressed. Milk yield gradually reduced over time, and it was affected by the type of diet. Conclusion Behavioural changes in dairy cows during transfer between housing systems featured adaptive characteristics and did not seem to be detrimental to the major research. Implications The transferring of cows from a group housing system to individual pens under the conditions used in this study did not jeopardise cow behaviour patterns to an extent that could affect other nutritional research outcomes.

Abstract
Malaysia Airlines flight 17 crashed on 17 July 2014 while flying over an area of armed conflict in eastern Ukraine. The first forensic trace evidence was collected after the human remains were transferred to a safe location in the Netherlands for identification and repatriation. Disaster victim identification processes were therefore undertaken in concert with the forensic investigation. Prior to these processes, X-ray and computed tomography scanners were used to reveal foreign objects in the human remains, and a large number of these fragments were recovered after the forensic triage. A distinct group of metal fragments was identified as being potential remnants of high-energy foreign objects. Forensic analysis revealed that they were explosively deformed unalloyed steel fragments, some of which had shapes consistent with pre-formed metal fragments found in a 9N314M warhead used in Buk SA-11 missiles. Furthermore, thin film deposits of cockpit glass and aluminium were identified on the most heavily deformed side of some of the explosively deformed metal fragments, suggesting they came from outside the airplane. These findings supported early suspicions that Malaysia Airlines flight 17 was struck by a Buk SA-11 missile. KeypointsA multidisciplinary approach for combined identification and forensic investigation of human remains after a mass fatality incident.The combined use of complementary X-ray techniques for detection and provisional characterization of foreign objects in human remains.The use of sensitive and highly discriminative state of the art techniques for analysing foreign objects recovered from human remains.

By taking into account the annihilation of dark matter pairs into mono-energetic photons, we found that for masses of O(102) GeV, an electric dipole moment ∼10−16 e cm is required to satisfy the current relic density inferences. Additionally, in order to pin down models viable to describe the physics of dark matter at the early Universe, we also constrain our model according to recent measurements of the temperature anisotropies of the cosmic microwave background radiation, and report constraints to the electric and magnetic dipole moments for a range of masses within our model.
Boron–nitrogen co-terminated diamond (110) surface for nitrogen-vacancy quantum sensors from first-principles calculations
Authors: Zhaolong Sun , Nan Gao 
Published: November 2022

Abstract
The nitrogen-vacancy (NV) center in diamond surface is a critical issue in quantum sensors with no sensitivity to surface terminators. We investigate the structural stabilities and electronic properties of boron (B)–N co-terminated diamond (110) surface based on first-principles calculations. The B–N co-terminated diamond (110) surfaces combined with monolayer coverage of hydrogen (H) and fluorine (F) adsorption are dynamically and thermally stable. Remarkably, the H/F mixed (H/F = 1.0) adsorption surface has neither surface spin noise nor surface-related state, and a positive electron affinity of 1.11 eV, thus it could be a prospective candidate for NV-based quantum sensors.
Transport characteristics and lattice dynamics with phonon topology accentuation in layered CuTlX (X: S, Se)
Authors: Sahoo Sushree Sarita , Kanchana V 
Published: November 2022

Abstract
In recent years, numerous Cu-based compounds have attracted a great deal of interest for enhanced thermoelectric energy conversion. Here, we demonstrate that CuTlX (X: S, Se), a layered semiconductor, exhibits low lattice thermal conductivity (κ

l
) and a high thermoelectric figure of merit (ZT), using density functional theory calculations and Boltzmann transport theory beyond relaxation time approximation. To evaluate the absolute values of thermoelectric coefficients, different scattering mechanisms such as acoustic deformation potential scattering, impurity phonon scattering, and polar optical phonon scattering are analysed. This low lattice thermal conductivity, which is complemented by a low group velocity and a low phonon lifetime, accounts for the remarkable thermoelectric efficiency in these compounds. In CuTlS, the contribution of the in-plane optical phonon mode to κ

l
results in a decrease in its value, which might be attributed to the occurrence of Dirac-like crossings with non-trivial topological characteristics, as corroborated by the non-zero Berry curvature value. Overall, the thermoelectric behavior of both compounds is favorable at ambient temperature. Specifically, the out-of-plane direction in CuTlSe presents elevated thermoelectric performance with a high value for the thermoelectric figure of merit, with 1.08 and 1.16 for holes and electrons, respectively, at 300 K at the optimal carrier density of 1019 cm−3 , which well aids in both the electron and phonon transport. We also undertook monolayer examinations of these compounds due to the existence of van der Waals interactions, which predicted strong thermoelectric performance for both carrier concentrations at 300 K. As a result, our study presents a theoretical prediction on transport phenomena that requires experimental verification and should motivate additional research into prospective thermoelectric materials in the same crystal family for device applications.
Cosmological constraints from the power spectrum and bispectrum of 21cm intensity maps
Authors: Karagiannis Dionysios , Maartens Roy , Randrianjanahary Liantsoa F. 
Published: November 2022

AbstractThe 21cm emission of neutral hydrogen is a potential probe of the matter distribution in the Universe after reionisation. Cosmological surveys of this line intensity will be conducted in the coming years by the SKAO and HIRAX experiments, complementary to upcoming galaxy surveys. We present the first forecasts of the cosmological constraints from the combination of the 21cm power spectrum and bispectrum. Fisher forecasts are computed for the constraining power of these surveys on cosmological parameters, the BAO distance functions and the growth function. We also estimate the constraining power on dynamical dark energy and modified gravity. Finally we investigate the constraints on the 21cm clustering bias, up to second order. We take into account the effects on the 21cm correlators of the telescope beam, instrumental noise and foreground avoidance, as well as the Alcock-Paczynski effect and the effects of theoretical errors in the modelling of the correlators. We find that, together withPlanckpriors, and marginalising over clustering bias and nuisance parameters, HIRAX achieves sub-percent precision on the ΛCDM parameters, with SKAO delivering slightly lower precision. The modified gravity parameter γ is constrained at 1% (HIRAX) and 5% (SKAO). For the dark energy parametersw0,wa, HIRAX delivers percent-level precision while SKAO constraints are weaker. HIRAX achieves sub-percent precision on the BAO distance functionsDA, H, while SKAO reaches 1 - 2% for 0.6 ≲z≲ 1. The growth ratefis constrained at a few-percent level for the whole redshift range of HIRAX and for 0.6 ≲z≲ 1 by SKAO. The different performances arise mainly since HIRAX is a packed inteferometer that is optimised for BAO measurements, while SKAO is not optimised for interferometer cosmology and operates better in single-dish mode, where the telescope beam limits access to the smaller scales that are covered by an interferometer.

The Unusual AGN Host NGC 1266: Evidence for Shocks in a Molecular Gas Rich S0 Galaxy with a Low Luminosity Nucleus
Authors: Chen Peibin , Zhao Yinghe , Wang Junfeng 
Published: November 2022

Abstract
NGC 1266 is a lenticular galaxy (S0) hosting an active galactic nucleus (AGN), and known to contain a large amount of shocked gas. We compare the luminosity ratio of mid-J CO lines to IR continuum with star-forming galaxies (SFGs), and then model the CO spectral line energy distribution (SLED). We confirm that in the mid- and high-J regions (J
up = 4–13), the C-type shock (v
s = 25 km s−1, n
H = 5 × 104 cm−3) can reproduce the CO observations well. The galaxy spectral energy distribution (SED) is constructed and modeled by the code X-CIGALE and obtains a set of physical parameters including the star formation rate (SFR, 1.17 ± 0.47 M
⊙ yr−1). Also, our work provides SFR derivation of [C ii] from the neutral hydrogen regions only (1.38 ± 0.14 M
⊙yr−1). Previous studies have illusive conclusions on the AGN or starburst nature of the NGC 1266 nucleus. Our SED model shows that the hidden AGN in the system is intrinsically low-luminosity, consequently the infrared luminosity of the AGN does not reach the expected level. Archival data from NuSTAR hard X-ray observations in the 3–79 keV band shows a marginal detection, disfavoring presence of an obscured luminous AGN and implying that a compact starburst is more likely dominant for the NGC 1266 nucleus.

Abstract
Organoids, and in particular patient-derived organoids, have emerged as crucial tools for cancer research. Our organoid platform, which has supported patient-derived tumor organoids (PTOs) from a variety of tumor types, has been based on the use of hyaluronic acid (HA) and collagen, or gelatin, hydrogel bioinks. One hurdle to high throughput PTO biofabrication is that as high-throughput multi-well plates, bioprinted volumes have increased risk of contacting the sides of wells. When this happens, surface tension causes bioinks to fall flat, resulting in 2D cultures. To address this problem, we developed an organoid immersion bioprinting method—inspired by the FRESH printing method—in which organoids are bioprinted into support baths in well plates. The bath—in this case an HA solution—shields organoids from the well walls, preventing deformation. Here we describe an improvement to our approach, based on rheological assessment of previous gelatin baths versus newer HA support baths, combined with morphological assessment of immersion bioprinted organoids. HA print baths enabled more consistent organoid volumes and geometries. We optimized the printing parameters of this approach using a cell line. Finally, we deployed our optimized immersion bioprinting approach into a drug screening application, using PTOs derived from glioma biospecimens, and a lung adenocarcinoma brain metastasis. In these studies, we showed a general dose dependent response to an experimental p53 activator compound and temozolomide (TMZ), the drug most commonly given to brain tumor patients. Responses to the p53 activator compound were effective across all PTO sets, while TMZ responses were observed, but less pronounced, potentially explained by genetic and epigenetic states of the originating tumors. The studies presented herein showcase a bioprinting methodology that we hope can be used in increased throughput settings to help automate biofabrication of PTOs for drug development-based screening studies and precision medicine applications.

Abstract
Increasing concentrations of atmospheric CO2 are projected to have positive effects on crop photosynthesis and yield (CO2 fertilization effect, CFE). High-temperature events, such as heatwaves, during sensitive periods can have significant negative impacts on crop yield and quality; however, the combined effects of elevated CO2 (EC) and short-period elevated temperature (ET) have not been determined in the open field. Here, we show a strong negative interaction between EC and ET obtained from a temperature-free-air controlled enhancement treatment embedded in a season-long free-air CO2 enrichment (FACE) experiment on a japonica rice cultivar, Koshihikari, over three seasons at the Tsukuba FACE facility in Ibaraki, Japan. CFE was 15% at ambient temperature, but it was reduced to 3% by ET, where canopy surface temperature (Tc) was elevated by ∼1.6 °C for 20 d after flowering. Reductions in CFE mainly arose from poor grain setting at Tc above ∼30 °C. High Tc also increased the percentage of chalky grains and substantially decreased the grain appearance quality, although the threshold temperature varied between the seasons. Simultaneous increases in atmospheric CO2 concentration and air temperature are expected to increase daytime canopy temperatures more than air warming alone, thereby affecting grain yield and quality. Crop models without these processes are likely to underestimate the negative impacts of climate change on crop yield and quality. The development of adaptation measures against heat stress, particularly during reproductive and grain-filling periods, needs to be enhanced and accelerated.
Bioaccumulation of silver nanoparticles in marine copepod Tigriopus japonicus under waterborne and dietary exposure
Authors: Liu Chenge , Liu Wenxia 
Published: November 2022

Abstract
At present, the emission of silver nanoparticles (AgNPs) will affect a variety of aquatic organisms. AgNPs may be transferred to the food web through the bioaccumulation or biomagnification of the food chain, which is harmful to at higher trophic level organisms, and even threatens human health. Therefore, in this study, we tested the acute toxicity effect of AgNPs to marine copepod Tigriopus japonicus, and analyzed the Ag bioaccumulation in T. japonicus under short-term waterborne (exposure of AgNPs to T. japonicus) and dietary exposure (AgNP-accumulated algae cells of Isochrysis galbana are used to feed T. japonicus). The results showed that, after 48 h exposure, significant effects of AgNPs on the mortalities were observed (LC50=6.330 mg·L−1). The bioaccumulation of Ag by T. japonicus under different exposure modes was positively correlated with exposure concentration and time, and the bioaccumulation level under waterborne exposure was significantly higher. The biomagnification of T. japonicus was not observed under 24 h dietary exposure of different AgNP concentrations (BMFs<1), but the transfer efficiency was higher under low exposure concentration (BMFlow concentration>BMFhigh concentration). This study is helpful to understand the toxicity mechanism and effect of AgNPs on aquatic organisms.
Reaction of Japanese media to discharging Fukushima nuclear waste water into ocean and the analysis----taking relevant reports of Japanese media as examples
Authors: Li Guangzhen , Li Zilong 
Published: November 2022

Abstract
Japanese government published the decision that the stored nuclear waste water in Fukushima Daiichi Nuclear Power Plant would be discharged into ocean, which met with violent objection from surrounding countries. Japanese domestic media reported in succession, and expressed a strong disagreement. And Fukushima local media were full of worries. They believed that local life and fishery production would be influenced for long. Being made a general observation of Japanese media, million tons of treated nuclear waste water discharged into ocean would be quite harmful to the environment. Japanese domestic attitude presented a distinct objection to the decision about discharging nuclear waste water into ocean made by Japanese government.
Comparison and study of several methods for solving the hydraulic jump values in pumping well

Abstract
This paper was envisaged to provide deeper insights of the hydraulic jump value in pumping well in the loess aquifer. Herein, we discussed the research status and problems of the value, compared the differences between the analytical solution method and the empirical formula method. Subsequently, we proposed a fitting method with improvement and the tangent method to estimate the hydraulic jump value, and quantitatively analyzed the linear variation rule of the water level curve around the well. The results show that the value calculated by the traditional empirical formula was about one tenth of the theoretical value in constant flow and the water level around the well was found to be logarithmic in the range of N1∼N3. When the range was extended, the water level curve changed to a parabolic nature and power function in turn. The hydraulic jump value obtained by h-r extension of the modified water level curve fitting equation was improved greatly, and the average error was found to be less than 1 m. The stability of the hydraulic jump value using the tangent method was poor, and the estimated horizontal distance was larger than 3 m. The results show that the reliability of the improved curve fitting method was better, while the empirical formula method and the tangent method exhibited a larger error and poor stability. When the error correction was performed, the improved curve fitting method could be used to estimate the hydraulic jump value under the same conditions, and can replace the theoretical calculation value.

Published: November 2022

Abstract
Fluid calculation simulation software was used to simulate the sludge blending in a 1000MW coal-fired power station boiler to study the effect of different blending ratios on the generation and emission of NOx, SO2, and CO. In this paper, the total calorific value of blending is kept constant for blending. The results show that the furnace chamber temperature decreases with increasing blending ratio. NOX concentration also decreases with increasing blending ratio. SO2 and CO concentrations gradually increase at the burner nozzle of the blended sludge, and the SO2 concentration at the furnace outlet is on the rise.

Published: November 2022

Abstract
Various uncertain influencing factors and incomprehensible mechanisms have posed daunting challenges to the management and treatment of regional surface water environment quality. The unified measures and the “one-size-fits-all” management approach limit the treatment effectiveness. Therefore, considering natural and human activities which are major factors affecting the surface water environment quality, the present study proposed a set of zoning management and control schemes for nitrogen and phosphorus concentrations in surface water based on its natural attributes. Selecting DEM, rainfall, vegetation type, soil type, and land use, and employing “grid transformation”, “data extraction”, “attribute superposition” of GIS software and “correlation analysis”, “cluster analysis”, and “principal component analysis” of SPSS software, the Haihe River Basin was divided into the prevention zone, the control zone, and the non-control zone with different natural attribute sets by the correlation coefficient R2 and the nitrogen and phosphorus pollution therein. Based on the nitrogen and phosphorus data of 276 surface water quality monitoring sites, the multiple nonlinear stepwise regression analysis was conducted to construct the relationship between a single water quality indicator and its natural attributes in the three zones. The results are of essential practical significance to surface water environment quality zoning management and survey in the Haihe River Basin. Meanwhile, it provides innovative insights into environmental zoning management in other regions.
