Authors: Rioux-Forker Dana , Patel Raahil S. , Hinchcliff Katharine M. , Shin Alexander Y. 
Published: May 2023

Abstract
Background The inclusion of the third carpometacarpal (CMC) joint in the fusion mass in total wrist fusion (TWF) remains controversial. Our goal was to evaluate the clinical outcomes and effects of third CMC joint arthrodesis compared with bridging the CMC joint during TWF. A retrospective chart review was performed. Outcomes assessed included hardware loosening, hardware failure, symptomatic hardware necessitating removal, and need for revision arthrodesis.
Case Description/Literature Review We found that concomitant third CMC joint arthrodesis was associated with a significantly reduced rate of radiocarpal and midcarpal joint nonunion, hardware loosening, and symptomatic hardware removal when compared to bridging of the CMC joint. There was no significant difference in hardware failure rates or the need for revision arthrodesis.
Clinical Relevance When using a contoured dorsal spanning plate, concomitant CMC joint arthrodesis should be considered during TWF to mitigate against hardware loosening and symptomatic hardware.

Published: May 2023

This work investigated the oxidation suppression effect of a reduced graphene oxide (rGO) film applied to a Cu substrate, which may have application in electrical connectors. To ensure prolonged low electrical contact resistance, a thin GO film was formed using an electrophoretic deposition method and subsequently heated to generate rGO. The surface morphology and thickness of the rGO film were assessed using atomic force microscopy and transmission electron microscopy. The thickness of the rGO film was estimated to be 5–7 nm, and the electrical contact resistance for the Cu substrate with and without an rGO film was 20 and 8 mΩ, respectively, at a contact load of 2 N. After accelerating the oxidation of the substrate by heating for 30 min at 180 °C under a dry air atmosphere, the formation of a Cu2O layer on the Cu substrate was confirmed by Raman spectroscopy and electron energy loss spectroscopy. The thickness of this oxide layer with and without an rGO film was 1.5 and 6 nm, respectively. In addition, the electrical contact resistance for the Cu substrate with and without the rGO film was 40 and 200 mΩ, respectively, at a contact load of 2 N. These results suggest that the thin rGO coating suppressed oxidation of the metal substrate while also suppressing the increase in contact resistance.

The upconversion color tuning of Lanthanide ions usually requires complex core–shell structures and excitation configurations. This work presents simple Er3+ doped Yttria phosphors capable of color change through the manipulation of 1530 nm excitation intensity. Compared to the reported results of Er3+ color change from green to red with the increase in excitation intensity, the formed color-tunable phosphors show an inverse change of red to green. The color tuning mechanisms are attributed to the competition between the upward absorption and the downward decay at the Er3+ intermediate state. Finally, the potential applications of the formed color-tunable phosphors are demonstrated. This work provides a simple solution for high-performance upconversion color tuning and thus shows wide application prospects.

Published: May 2023

Based on steady-state experiments, a three-dimensional (3D) simulation study under pulsation conditions was carried out. This was performed to study the effect of pulsation of the supply system on the atomization characteristics of a gas-centered swirl coaxial injector. The results indicated that the spray shape resembled a pagoda when the Klystron effect occurred. When the low-frequency pulsation (200 Hz) was applied to the liquid inlet, the peak of the exit pressure was close to the trough of the inlet mass flow rate. Meanwhile, the exit mass flow rate and pressure were approximately sinusoidal. There was no significant lag effect in the response of the exit mass flow rate to the inlet mass flow rate but with a small sawtooth-like oscillation. Increasing the amplitude of the liquid inlet disturbance amplified the exit mass flow rate fluctuation, which was greater than the set amplitude of the inlet pulsation. The dominant frequency of the injector exit mass flow rate and pressure variation was significantly less than the inlet pulsation frequency when the frequency of the liquid inlet pulsation was increased to 1000 Hz. This was due to the low-pass filtering effect of the annular slit. There was no significant change in the overall spray morphology for the gas inlet pulsation. By applying the same amplitude and frequency of pulsation to the gas and liquid inlets of the injector, the pulsation of the liquid inlet had a stronger effect on the injector exit spray than that of the gas inlet.

We have studied the decomposition of methanol-d4 on thin film Al2O3/NiAl(100) under near-ambient-pressure conditions, with varied surface-probe techniques and calculations based on density-functional theory. Methanol-d4 neither adsorbed nor reacted on Al2O3/NiAl(100) at 400 K under ultrahigh vacuum conditions, whereas they dehydrogenated, largely to methoxy-d3 (CD3O*, * denoting adsorbates) and formaldehyde-d2 (CD2O*), on the surface when the methanol-d4 partial pressure was increased to 10−3 mbar and above. The dehydrogenation was facilitated by hydroxyl (OH* or OD*) from the dissociation of little co-adsorbed water; a small fraction of CD2O* interacted further with OH* (OD*) to form, via intermediate CD2OOH* (CD2OOD*), formic acid (DCOOH* or DCOOD*). A few surface carbonates were also yielded, likely on the defect sites of Al2O3/NiAl(100). The results suggest that alumina not only supports metal clusters but also participates in reactions under realistic catalytic conditions. One may consider accordingly the multiple functions of alumina while designing ideal catalysts.

Published: May 2023

Recently, room-temperature superconductivity has been reported in a nitrogen-doped lutetium hydride at near-ambient pressure [Dasenbrock-Gammon et al., Nature 615, 244 (2023)]. The superconducting properties might arise from Fm3̄m-LuH3−δNε. Here, we systematically study the phase diagram of Lu–N–H at 1 GPa using first-principles calculations, and we do not find any thermodynamically stable ternary compounds. In addition, we calculate the dynamic stability and superconducting properties of N-doped Fm3̄m-LuH3 using the virtual crystal approximation (VCA) and the supercell method. The R3m-Lu2H5N predicted using the supercell method could be dynamically stable at 50 GPa, with a Tc of 27 K. According to the VCA method, the highest Tc is 22 K, obtained with 1% N-doping at 30 GPa. Moreover, the doping of nitrogen atoms into Fm3̄m-LuH3 slightly enhances Tc, but raises the dynamically stable pressure. Our theoretical results show that the Tc values of N-doped LuH3 estimated using the Allen–Dynes-modified McMillan equation are much lower than room temperature.
The hypothermic nature of fungi

Published: May 2023

Fungi play essential roles in global health, ecology, and economy, but their thermal biology is relatively unexplored. Mushrooms, the fruiting body of mycelium, were previously noticed to be colder than surrounding air through evaporative cooling. Here, we confirm those observations using infrared thermography and report that this hypothermic state is also observed in mold and yeast colonies. The relatively colder temperature of yeasts and molds is also mediated via evaporative cooling and associated with the accumulation of condensed water droplets on plate lids above colonies. The colonies appear coldest at their center and the surrounding agar appears warmest near the colony edges. The analysis of cultivatedPleurotus ostreatusmushrooms revealed that the hypothermic feature of mushrooms can be observed throughout the whole fruiting process and at the level of mycelium. The mushroom’s hymenium was coldest, and different areas of the mushroom appear to dissipate heat differently. We also constructed a mushroom-based air-cooling prototype system capable of passively reducing the temperature of a semiclosed compartment by approximately 10 °C in 25 min. These findings suggest that the fungal kingdom is characteristically cold. Since fungi make up approximately 2% of Earth’s biomass, their evapotranspiration may contribute to cooler temperatures in local environments.

Asevolution: a relativistic N-body implementation of the (a)symmetron
Authors: Christiansen Øyvind , Hassani Farbod , Jalilvand Mona , Mota David F. 
Published: May 2023

Abstract
We present asevolution, a cosmological N-body code developed based on gevolution, which consistently solves for the (a)symmetron scalar field and metric potentials within the weak-field approximation. In asevolution, the scalar field is dynamic and can form non-linear structures.
A cubic term is added in the symmetron potential to make the symmetry-broken vacuum expectation values different, which is motivated by observational tensions in the late-time universe. To study the effects of the scalar field dynamics, we also implement a constraint solver making use of the quasi-static approximation, and provide options for evaluating the background evolution, including using the full energy density averaged over the simulation box within the Friedmann equation. The asevolution code is validated by comparison with the Newtonian N-body code ISIS that makes use of the quasi-static approximation. There is found a very small effect of including relativistic and weak-field corrections in our small test simulations; it is seen that for small masses, the field is dynamic
and can not be accurately solved for using
the quasi-static approximation;
and we observe
the formation of unstable domain walls and demonstrate a useful way to identify them within the code. A first consideration indicates that the domain walls are more unstable in the asymmetron scenario.

Published: May 2023

Abstract
Traditional stellar classification methods include spectral and photometric classification separately. Although satisfactory results can be achieved, the accuracy could be improved. In this paper, we pioneer a novel approach to deeply fuse the spectra and photometric images of the sources in an advanced multimodal network to enhance the model’s discriminatory ability. We use Transformer as the fusion module and apply a spectrum–image contrastive loss function to enhance the consistency of the spectrum and photometric image of the same source in two different feature spaces. We perform M-type stellar subtype classification on two data sets with high and low signal-to-noise ratio (S/N) spectra and corresponding photometric images, and the F1-score achieves 95.65% and 90.84%, respectively. In our experiments, we prove that our model effectively utilizes the information from photometric images and is more accurate than advanced spectrum and photometric image classifiers. Our contributions can be summarized as follows: (1) We propose an innovative idea for stellar classification that allows the model to simultaneously consider information from spectra and photometric images. (2) We discover the challenge of fusing low-S/N spectra and photometric images in the Transformer and provide a solution. (3) The effectiveness of Transformer for spectral classification is discussed for the first time and will inspire more Transformer-based spectral classification models.
Ammonia production in a dual crossed atom beam experiment

Published: May 2023

Abstract
Production of ammonia by surface reactions of H and N atoms on surfaces not wetted by partially ionized plasma may represent an important technological issue in fusion reactors where puffing nitrogen is employed to cool plasma in the divertor region. The H and N atoms are likely to interact on such surfaces forming NH3 molecules. The interaction efficiency was studied in a laboratory setup consisting of two separate sources of either N or H atoms. Both sources enabled experiments with atoms at room temperature in the range of H-atom density of the order of 1021 m−3 and N-atom density of the order of 1020 m−3. The production of ammonia was measured with a calibrated residual gas analyser. The production depended on the fluxes of both atoms onto the surface of selected materials. As a general rule, the higher H-atom flux at a constant N-atom flux caused an increase in ammonia production. The highest efficiency of up to 50% was found for nickel. It was up to 30% for tungsten, whereas for P92 alloy, it was up to about 20%. The accuracy of these results is within about ±20% of the measured values. Methods for suppressing ammonia formation in fusion reactors will have to be invented in order to enable appropriate long-term operation.

Published: May 2023

Abstract
Retaining wall type contiguous pile is a structure that serves to hold and stabilize the soil in certain soil conditions. Retaining walls can be deformed by various factors. This research on retaining walls compares the deformation results between the actual data, the finite element method with the Mohr - Coulomb, Soft Soil and Hardening Soil parameters, and find the safety factor based on SNI Geotechnical 8460:2017. The result of this research is that the deformation value of Mohr - Coulomb modelling is closer than the actual value in the field, followed by the modelling of Soft Soil & Hardening Soil, Soft Soil & Mohr-Coulomb, and Hardening Soil. This difference occurs because there are differences in the correlation approach and the type of undrained type used. It was found that the Mohr - Coulomb parameter is better than the other parameters with a deformation result of 24.5 mm with a safety factor of 1.675 which is close to the actual data.

Authors: Erizal Muhamad Iqbal , Suwondo Riza , Suangga Made 
Published: May 2023

Abstract
Along with development of the method for calculating the stability of steel structures, the direct analysis method is one of the recommended methods. This method is adopted by many design codes including AISC 360 and SNI 1729:2020. The direct analysis method has been considered as the primary method since it can overcome the limitations of the previous method, known as the effective length method. The main objective of this study is to understand the application of the direct analysis method on the long span steel structures. This research considers the effect of building height, earthquake loads, and gravity loads on the steel structure stability. The results show that the direct analysis method is a simpler and more efficient method since it has taken into account the second-order effect and has a smaller stress ratio value compared to the Effective Length Method. Therefore, the direct analysis method can be used as a recommendation method for calculating the stability of steel structures.

Published: May 2023

Abstract
Breadfruit plant also known as Artocarpus altilis, is a plant that lives in tropical climate. This plant has various advantages neither for consumption nor health. This makes some people interested in growing breadfruit plants. However, most people still do not know breadfruit leaves can be beneficial, so it often ends up as organic waste or compost. From the problem that has been mentioned, dried breadfruit leaves have the potential to be used for other things such as particle board material. Particle board is made from wood chips and adhesive such as resin that are processed at high temperature also pressed until it become a board. The theory and method that are used in these experiments is quantitative to know whether dried breadfruit leaves have a good quality as particle board material or not. The experiments use different variables and will be compared to determine which experiments have the best quality. With this experiments method, the expected result is that dried breadfruit leaves can be used as particle board material with a good strength and density.
Development of ready-to-eat (RTE) liwet rice with corn analog rice substitution as an alternative food in emergency conditions
Authors: Rubby M , Oktarina R , Amrinola W 
Published: May 2023

Abstract
This research aims to develop ready-to-eat (RTE) rice based on local food, namely liwet rice which is substituted with corn analog rice. This RTE rice is intended for food supplies in disaster emergencies and still contributes to the food diversification program. The RTE liwet rice production carried out in this study was by using the retort process. The retort process was carried out using an autoclave at 121 0C for 15 minutes and used retort pouch packaging. The RTE liwet rice in this study made used five formulations of corn analog rice substitution, namely 0%, 20%, 30%, 40%, and 50%. The resulting liwet rice was then analyzed for its physicochemical and organoleptic characteristics. The results showed that the substitution of corn analog rice had a significant effect on the proximate content and physical properties (texture and color) of the liwet rice produced but did not significantly affect the pH and organoleptic characteristics. The best formula in this study was obtained in the 30% substitution of corn analog rice.
