WEAVING AN EXPANDED SONIC PRACTICE: PROPOSING A TEXTILIC SONIC METHOD
Authors: G'Froerer Callum
Published: September 2023

This article discusses the way textile metaphors can act as catalysts for reflection in my practice as a trumpet performer and composer. Metaphors such as ‘fibre’, ‘spin’, ‘yarn’, ‘ply’, ‘weave’, ‘loom’, ‘drape’ and ‘felt’ are engaged as lenses through which the dynamic, contingent and tailorable interactions are made between sonic and extra-sonic elements in my expanded practice. The metaphors are engaged to shape instrumental techniques, improvisation, form, audiovisual media, physicality and spatial design. In this article, I describe how I developed my own expanded sonic practice by using Tim Ingold's concept of ‘textility’, expressed as a Textile Sonic Method (TSM). I demonstrate the application of this method using a subset of textile metaphors as the basis for the development of new double-bell trumpet techniques and applications in a range of compositions: Gradient (2020–23), for double-bell trumpet, live video and sound processing, co-composed with Olivia Davies and Nick Roux; Untitled (2021), for double-bell trumpet, portative organ and electronics, co-composed with James Rushford; and my own work Charcoal VI (2017), for spatialised, amplified double-bell trumpet. This article outlines the potential for the application of metaphor as a creative catalyst in an expanded sonic practice.

Vanilla insignisAmes. (Orchidaceae): morphological variation of the labellum in Quintana Roo, Mexico
Authors: Herrera-Cabrera B. Edgar , Hernández-Silva Néstor , Delgado-Alvarado Adriana , Maceda Agustín
Published: September 2023

The shape of the flower can vary based on the type of pollinator or the environment in which the plant develops. InVanilla insignis, there are no studies that analyse the shape of the labellum of the flower as has been done inV. planifolia. Therefore, the study aimed to determine the variation in the shape of the labellum ofV. insignisthrough a morphometric analysis in different environmental conditions in the state of Quintana Roo, Mexico. The results showed that there were significant differences in the variables analysed. Principal component analysis and dendrogram analysis reveal that fourV. insignismorphotypes were possibly associated with soil water availability conditions because there were significant differences between the variables that define the apical region. In addition, the distribution of the morphotypes corresponded with the presence of humidity regardless of geographical distances such as in the populations of Tenampulco, Puebla and Caobas, Quintana Roo. The presence of these morphotypes allows the development of conservation programmes and genetic improvement of the species ofV. insignisand related commercial species.
Arctic Tundra Lake Drainage Increases Snow Storage in Drifts
Authors: Rangel R. C. , Ohara N. , Parsekian A. D. , Jones B. M.
Published: September 2023

Snowdrifts formed by wind transported snow deposition represent a vital component of the earth surface processes on Arctic tundra. Snow accumulation on steep slopes particularly at the margins of rivers, coasts, lakes, and drained lake basins (DLBs) comprise a significant water storage component for the ecosystem during spring and summer snowmelt. The tundra landscape is in constant change as lakes drain, substantially altering the surface morphology that partially controls how snow drifts and accumulates throughout the cold seasons. Here, we combine field measurements, remote sensing observations, and snow modeling to investigate how lake drainage affects snow redistribution at Inigok on the Arctic Coastal Plain of Alaska, where the snow movement is controlled by wind. Field observations included measurements of snow depth using ground penetrating radar and probe. We mapped mid‐July snow cover and modeled snow redistribution before and after drainage simulation for 33 lakes (∼30 km2) in our study area (∼140 km2). Our results show the advantage of using a wide range of snow depth measurements on frozen lakes, DLBs, and upland to validate the snow modeling in order to capture the variability inherent in the landscape. The lake drainage simulation suggests an increase in snow storage of up to ∼24% at DLBs compared to extant lakes, ∼35% considering only snowdrifts (assumed as ≥1 m depth), and ∼4% considering the whole study area. This increase in snow accumulation could significantly impact the landscape when it melts, including wildlife, vegetation, biogeochemical processes, and potential natural hazards like snow‐dam outburst floods.

Published: September 2023

Burn injuries are one of the leading causes of morbidity worldwide. Although the overall incidence of burns and burn-related mortality is declining, these factors have not been analysed in our population for 25 years. The aim of this study has been to determine whether the epidemiological profile of patients hospitalized for burns has changed over the past 25 years. We performed a retrospective cohort study of patients hospitalised between 1 January 2011 and 31 December 2018 with a primary diagnosis of burns. The incidence of burns in our setting was 3.68/105 population. Most patients admitted for burns were men (61%), aged between 35 and 45 years (16.8%), followed by children aged between 0 and 4 years (12.4%). Scalding was the most prevalent mechanism of injury, and the region most frequently affected was the hands. The mean burned total body surface (TBSA) area was 8.3%, and the proportion of severely burned patients was 9.7%. Obesity was the most prevalent comorbidity (39.5%). The median length of stay was 1.8 days. The most frequent in-hospital complications were sepsis (16.6%), acute kidney injury (7.9%), and cardiovascular complications (5.9%). Risk factors for mortality were advanced age, high abbreviated burn severity index score, smoke inhalation, existing cardiovascular disease full-thickness burn, and high percentage of burned TBSA. Overall mortality was 4.3%. Multi-organ failure was the most frequent cause of death, with an incidence of 49.5%. The population has aged over the 25 years since the previous study, and the number of comorbidities has increased. The incidence and severity of burns, and the percentage of burned TBSA have all decreased, with scalding being the most prevalent mechanism of injury. The clinical presentation and evolution of burns differs between children and adults. Risk factors for mortality were advanced age, smoke inhalation, existing cardiovascular disease, full-thickness burn, and high percentage of burned TBSA.

With the SARS-CoV-2 pandemic and the need for affordable and rapid mass testing, colorimetric isothermal amplification reactions such as Loop-Mediated Isothermal Amplification (LAMP) are quickly rising in importance. The technique generates data that is similar to quantitative Polymerase Chain Reaction (qPCR), but instead of an endpoint color visualization, it is possible to construct a signal over a time curve. As the number of works using time-course analysis of isothermal reactions increases, there is a need to analyze data and standardize their related treatments quantitatively. Here, we take a step forward toward this goal by evaluating different available data treatments (curve models) for amplification curves, which allows for a cycle threshold-like parameter extraction. In this study, we uncover evidence of a double sigmoid equation as the most adequate model to describe amplification data from our remote diagnostics system and discuss possibilities for similar setups. We also demonstrate the use of multimodal Gompertz regression models. Thus, this work provides advances toward standardized and unbiased data reporting of Reverse Transcription (RT) LAMP reactions, which may facilitate and quicken assay interpretation, potentially enabling the application of machine learning techniques for further optimization and classification.

Published: September 2023

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death in the world. Poor prognosis of HCC patients is a major issue, thus, better treatment options for patients are required. Curcumin (Cur), hydrophobic polyphenol of the plant turmeric, shows anti-proliferative, apoptotic, and anti-oxidative properties. Boron is a trace element which is essential part of human nutrition. Sodium pentaborate pentahydrate (NaB), a boron derivative, is an effective agent against cancer. In the current study, we performed in vitro experiments and transcriptome analysis to determine the response of NaB, Cur, piperine (Pip) and their combination in two different HCC cell lines, HepG2 and Hep3B. NaB and Cur induced cytotoxicity in a dose and time dependent manner in HepG2 and Hep3B, whereas Pip showed no significant toxic effect. Synergistic effect of combined treatment with NaB, Cur and Pip on HCC cells was observed on cytotoxicity, apoptosis and cell cycle assay. Following in vitro studies, we performed RNA-seq transcriptome analysis on NaB, Cur and Pip and their combination on HepG2 and Hep3B cells. Transcriptome analysis reveals combined treatment of NaB, Cur and Pip induces anti-cancer activity in both of HCC cells.

We assessed the potential retinal microcirculation alterations for postoperative visual recovery in sellar/paraseller tumor patients with Optical Coherence Tomography Angiography (OCT-A). Two hundred ten eyes with sellar/parasellar tumor for which preoperative and postoperative (3 months) MRI Scans, Visual Acuity Test, Optical Coherence Tomography (OCT), OCT-A and, Visual Field Test data were available, besides 92 healthy eyes were evaluated. In the preoperative phase, significant reductions were observed in retinal vascular densities in various regions, including the Superficial Retinal Capillary Plexus (SRCP) (whole: p < 0.001, fovea: p = 0.025, parafovea: p < 0.001), Deep Retinal Capillary Plexus (DRCP) (whole: p < 0.001, fovea: p = 0.003, parafovea: p < 0.001), Peripapillary Vascular Density (PVD) (whole: p = 0.045, peripapillary: p < 0.001, nasal: p < 0.001, inferior: p < 0.001, temporal: p < 0.001), and Retinal Nerve Fiber Layer (RNFL) (nasal: p = 0.024, inferior: p < 0.001, temporal: p < 0.001, superior: p < 0.001) compared to the healthy control group. After surgery, the postoperative data of patients without chiasmal distortion were compared to their preoperative data. In the postoperative evaluation, significant increases were observed in vascular densities in patients without chiasmal distortion in the SRCP (whole: p < 0.001, parafovea: p = 0.045), DRCP (whole: p = 0.007, fovea: p = 0.006, parafovea: p = 0.040), PVD (peripapillary: p = 0.010, inferior: p < 0.001, temporal: p < 0.001, superior: p < 0.001), and RNFL (nasal: p = 0.011, inferior: p = 0.034, temporal: p = 0.046, superior: p = 0.011). Furthermore, significant associations were observed in the ROC analysis between the postoperative Visual Field Mean Deviation (VFMD) and SRCP (whole AUC = 0.793, p < 0.001, cut-off = 51.45, parafovea AUC = 0.820, p < 0.001, cut-off = 53.95), DRCP (whole AUC = 0.818, p < 0.001, cut-off = 55.95, parafovea AUC = 0.820, p < 0.001, cut-off = 59.05), PVD (temporal AUC = 0.692, p < 0.001, cut-off = 55.10), and RNFL (whole AUC = 0.690, p = 0.001, cut-off = 119.5, inferior AUC = 0.712, p < 0.001, cut-off = 144.75). These findings indicate a potential role of pre and post-operative OCT-A measurements in the assessment of surgical timing and postoperative visual recovery in patients with or without optic chiasm distortion.

Published: September 2023

Single-cell technologies have revolutionised biological research and applications. As they continue to evolve with multi-omics and spatial resolution, analysing single-cell datasets is becoming increasingly complex. For biologists lacking expert data analysis resources, the problem is even more crucial, even for the simplest single-cell transcriptomics datasets. We propose ShIVA, an interface for the analysis of single-cell RNA-seq and CITE-seq data specifically dedicated to biologists. Intuitive, iterative and documented by video tutorials, ShIVA allows biologists to follow a robust and reproducible analysis process, mostly based on the Seurat v4 R package, to fully explore and quantify their dataset, to produce useful figures and tables and to export their work to allow more complex analyses performed by experts.

Published: September 2023

The present study successfully combined a stoichiometric bioenergetic approach with an endpoint stochastic model to simultaneously determine specific dynamic action, metabolic substrate use and whole-body protein synthesis in juvenile slipper lobster Thenus australiensis. Juvenile lobsters were fasted for 48 h to investigate routine metabolism before receiving a single meal of formulated feed containing 1% 15N-labeled Spirulina. Postprandial oxygen consumption rate, dissolved inorganic carbon, and total nitrogen excretion returned to the pre-feeding level within 24 h. The rate of whole-body protein synthesis was 0.76 ± 0.15 mg CP g−1 day−1, with a significant reduction from 24 to 48 h post-feeding. The postprandial increase in whole-body protein synthesis accounted for 13–19% of total oxygen uptake. Protein was the primary energy substrate for 48 h fasted (45% oxygen consumption) and post-feeding lobster (44%), suggesting that dietary protein was not efficiently used for growth. The secondary energy substrate differed between carbohydrates in 48 h fasted and lipids in post-feeding lobsters. The present study recommends integrating protein synthesis into protein requirement experiments of marine ectotherms to acquire a more comprehensive picture of protein and energy metabolism and nutritional physiology crucial for formulating cost-effective aquafeeds.

Published: September 2023

As the in-depth expansion and integrated application of information technology, smart city is one of the important directions for nurturing breakthroughs in the new generation of information technology, and an important part of the development of global strategic emerging industries. In the context of world peace, the world economy is developing rapidly and the process of urbanization is accelerating. The construction of a city not only reflects the economic strength of the city, but also is closely related to the life of the citizens. Therefore, this paper aimed to explore a new way of urban cultural creative design. This paper focused on the application of human–computer interaction virtual reality (VR) technology in urban cultural creative design. For this reason, this paper designed an interactive and immersive urban design simulation platform based on VR technology. In order to choose the viewing angle freely and control the design module freely, this paper proposed improved gesture recognition algorithm and anti-collision algorithm. The algorithm designed in this paper can enable designers to have better presentation effects when working on the platform, making architectural design more intuitive. Experiments show that the average accuracy rate of the gesture recognition algorithm designed in this paper reaches 97.3%, which is 4.1% higher than that of the traditional algorithm; and when the anti-collision algorithm in this paper is set to the optimal parameters, the accuracy rate is as high as 95%. These results fully demonstrate that the human–computer interaction VR technology design platform proposed in this paper has good design performance and can be applied to urban cultural creative design.

Authors: Hayes Richard S.
Published: September 2023

(J. Extra-Corpor. Technol. 19[3] p. 287-289 Fall 1987) We have developed a complete system for acquiring data directly from electronic monitoring devices in the OR and ICU. In addition, this system maintains a database used for documentation of clinical management, report generation, and archival analysis of general patient information and clinical treatment.

This system is microcomputer based and file driven. Monitoring of patients occurs in the operating room, ICU, office, and at home via modem.

Since the system is file driven, it can be configured for any operation. It can be reconfigured at any time, including during an operation as clinical situations dictate.

Data is entered simultaneously from direct interface with monitoring devices and also manually. And as data is entered, new calculations are performed (i.e., SVR, LVSWI) to provide current clinical data so decisions in clinical management can be made.

Published: September 2023

Introduction : L’intégration multisensorielle est un mécanisme fondamental permettant d’intégrer et synchroniser les différentes entrées sensorielles. Nous avons évalué l’impact de la variation sensorielle plantaire sur la fusion binoculaire. Méthode : La contribution de la modalité podale a été étudiée en faisant varier l’afférence plantaire par réduction (mousse) et augmentation (texture) objectivée au Maddox Perceptif en évaluant les Hétérophories Verticales (HV) et leur Labilité (L). 40 participants (28 adultes, 12 adolescents) présentant une HV ont été inclus. Les HV ont été évaluées de façon aléatoire sur différents sols en mousse (Crispon Diabète® (CD) et Airgom® (AG)) et sur sol texturé (Black Pyramides®, BP), en comparaison à un sol contrôle (dur). Résultat : CD et BP induisent une réduction significative des hétérophories verticales et une augmentation de leur labilité. Ces effets ne varient pas avec l’âge. Discussion : Les résultats suggèrent que la modalité sensorielle plantaire permet d’avoir une incidence immédiate sur les phories verticales s’exprimant par la réduction de ces dernières ainsi qu’une variation de leur index de labilité. Nous confirmons qu’il est possible de modifier la perception visuelle en réduisant ou en augmentant les informations sensorielles plantaires et suggérons que le système plantaire peut influencer la proprioception visuelle en impactant la fusion binoculaire.
Choosing a better communication style: revealing the relationship between communication style and knowledge hiding behaviour
Authors: Jiang Zhenyu , Wang Zongjun , Feng Chengxiao
Published: September 2023

In the era of the knowledge economy, knowledge hiding behaviour and its antecedents and consequences have been of great interest to the academic community. Through a survey of 350 employees of Chinese manufacturing enterprises, this paper explores the mechanism of organizational communication on employees’ knowledge hiding behaviour. The results of the regression analysis show that (1) cooperative communication will reduce employees’ knowledge hiding behaviour; in contrast, competitive communication will increase employees’ knowledge hiding behaviour. (2) There is no significant relationship between online communication and employees’ knowledge hiding behaviour. (3) Although online communication weakens the inhibitory effect of cooperative communication on employee knowledge hiding behaviour, it can alleviate employee knowledge hiding behaviour caused by competitive communication. This study reveals the association between communication styles and employees’ knowledge hiding behaviour, which not only deepens the understanding of the antecedents of knowledge hiding in the academic community but also provides guidance for corporate internal communication and knowledge management practises.
Neural network predicts ion concentration profiles under nanoconfinement
Authors: Cao Zhonglin , Wang Yuyang , Lorsung Cooper , Barati Farimani Amir
Published: September 2023

Modeling the ion concentration profile in nanochannel plays an important role in understanding the electrical double layer and electro-osmotic flow. Due to the non-negligible surface interaction and the effect of discrete solvent molecules, molecular dynamics (MD) simulation is often used as an essential tool to study the behavior of ions under nanoconfinement. Despite the accuracy of MD simulation in modeling nanoconfinement systems, it is computationally expensive. In this work, we propose neural network to predict ion concentration profiles in nanochannels with different configurations, including channel widths, ion molarity, and ion types. By modeling the ion concentration profile as a probability distribution, our neural network can serve as a much faster surrogate model for MD simulation with high accuracy. We further demonstrate the superior prediction accuracy of neural network over XGBoost. Finally, we demonstrated that neural network is flexible in predicting ion concentration profiles with different bin sizes. Overall, our deep learning model is a fast, flexible, and accurate surrogate model to predict ion concentration profiles in nanoconfinement.

Published: September 2023

As a follow-up study of Wang et al. [“Control of the flow around a finite square cylinder with a flexible plate attached at the free end,” Phys. Fluids 34(2), 027109 (2022)], this paper presents an experimental study of flow around a wall-mounted finite square cylinder with a vertically clamped flapping film at its free end. The width (d) of the square cylinder was 40 mm, and the aspect ratio (H/d) was 5, where the height H was 200 mm. The flexible film was made of low-density polyethylene, with a thickness of 0.04 mm and the width and length (l) each of d. Flow visualization and particle image velocimetry were conducted in the central lateral plane and several horizontal planes to reveal the 3D structure of the flapping induced vortex (FIV) and its effects on the cylinder near wake. All measurements were done in a low-speed wind tunnel at a flow speed of U∞ = 5 m/s with a Reynolds number of 13 700 based on U∞ and d. Previous study suggests that the flapping film reduces aerodynamic forces of the cylinder significantly and that the fluctuating lateral force is reduced by 60% [Wang et al., “Control of the flow around a finite square cylinder with a flexible plate attached at the free end,” Phys. Fluids 34(2), 027109 (2022)]. Vortices that shed from the trailing edge of the flapping film connect those from the side edges, forming n-shape FIVs downstream. FIVs induce more high-speed flow downwards into the wake, which suppresses the mean recirculation zone near the free end but enlarges it in the lower part of the wake. The two legs of n-shape FIVs are symmetrically arranged near the cylinder free end, whose effects diminish gradually as approaching the bottom wall, where alternating Karman vortex shedding still prevails.

DNA deformability and differential hydration are crucial determinants of biological processes ranging from genetic material packaging to gene expression; their associative details, however, remain inadequately understood. Herein, we report investigations of the dynamic and thermodynamic responses of the local hydration of a variety of base pair sequences. Leveraging in silico sampling and our in-house analyses, we first report the local conformational propensity of sequences that are either predisposed toward the canonical A- or B-conformations or are restrained to potential transitory pathways. It is observed that the transition from the unrestrained A-form to the B-form leads to lengthwise structural deformation. The insertion of intermittent -(CG)- base pairs in otherwise homogeneous -(AT)- sequences bears dynamical consequences for the vicinal hydration layer. Calculation of the excess (pair) entropy suggests substantially higher values of hydration water surrounding A conformations over the B- conformations. Applying the Rosenfeld approximation, we project that the diffusivity of water molecules proximal to canonical B conformation is least for the minor groove of the canonical B-conformation. We determine that structure, composition, and conformation specific groove dimension together influence the local hydration characteristics and, therefore, are expected to be important determinants of biological processes.

Published: September 2023

Ultra-thin capacitor structures of barium titanate (BaTiO3, BTO) nanocube monolayers are fabricated using graphene as an electrode without high-temperature sintering. The capacitor consists of a self-assembled BTO nanocube monolayer (approximately 20 nm in thickness) and an eight-layer graphene electrode (≤3 nm in thickness) that are sandwiched metal electrodes. The graphene electrode functions as a barrier layer preventing the occurrence of short circuits caused by the penetration of metal species into the dielectric layer during the deposition process of the metal electrode, dramatically reducing the leakage current of the capacitor in comparison with the case without the graphene electrode. Furthermore, this approach is applicable to the fabrication of the graphene/BTO-nanocube-monolayer multi-stacked structures, demonstrating the potential to reduce the thickness of individual electrode/dielectric layers in multilayer ceramic capacitors down to less than 25 nm. This opens up possibilities for energy-efficient production of high-performance ceramic capacitors.

Published: September 2023

This paper presents a piezoelectric energy harvesting device applicable to wireless mouse (WM-PEH). Adding magnetic force to the excitation piezoelectric generating unit makes the impact better and more pronounced. The polygonal roller can increase the excitation frequency of the piezoelectric generating unit and broaden the energy collection range and capability of the WM-PEH. The theoretical and simulation analysis of WM-PEH was carried out in this paper. The effects of the length ratio of the exciter rod to the support frame and the circular impact area on the output characteristics of the prototype were discussed in the experiment. When the length ratio of the exciter rod and the support rod is 3:1, the activity increment of the exciter rod is the largest, and the maximum output voltage can reach 42 V and the maximum output power is 22.43 mW when it acts on a circular generator set with a radius of 1.5 mm. The design of the device is highly integrated with the wireless mouse that is widely used, and the piezoelectric energy harvesting mechanism and the wireless mouse are perfectly combined, which provides a scientific basis for the subsequent development of a self-powered wireless mouse.

Published: September 2023

We present the chemical bonding and electronic properties of liquid methane at temperatures from 2000 to 4000 K and high densities of up to 3.0 g/cm3, calculated using ab initio molecular dynamics simulations in combination with the Mulliken population analysis. Bond-overlap populations and pair distribution functions are studied to investigate the evolution of electron delocalization accompanying atomic structure change as the density is increased. In addition, we also investigated the bandgap energy, electronic density of states, and spatial distribution of electron density. We observed that molecular hydrogen and C‒C bonds are formed after methane dissociates, and then the system undergoes a nonmetal–metal transition coinciding with hydrogen being transformed from the molecular to the atomic state. The C‒C bonds in the system retain covalent character, even at the highest density of 3.0 g/cm3.
A statistical mechanical model of supercooled water based on minimal clusters of correlated molecules

Published: September 2023

In this paper, we apply a theoretical model for fluid state thermodynamics to investigate simulated water in supercooled conditions. This model, which we recently proposed and applied to sub- and super-critical fluid water [Zanetti-Polzi et al., J. Chem. Phys. 156(4), 44506 (2022)], is based on a combination of the moment-generating functions of the enthalpy and volume fluctuations as provided by two gamma distributions and provides the free energy of the system as well as other relevant thermodynamic quantities. The application we make here provides a thermodynamic description of supercooled water fully consistent with that expected by crossing the liquid–liquid Widom line, indicating the presence of two distinct liquid states. In particular, the present model accurately reproduces the Widom line temperatures estimated with other two-state models and well describes the heat capacity anomalies. Differently from previous models, according to our description, a cluster of molecules that extends beyond the first hydration shell is necessary to discriminate between the statistical fluctuation regimes typical of the two liquid states.
Molecular insights into fluid-solid interfacial tensions in water + gas + solid systems at various temperatures and pressures

Published: September 2023

The fluid–solid interfacial tension is of great importance to many applications including the geological storage of greenhouse gases and enhancing the recovery of geo-resources, but it is rarely studied. Extensive molecular dynamics simulations are conducted to calculate fluid–solid interfacial properties in H2O + gas (H2, N2, CH4, and CO2) + rigid solid three-phase systems at various temperatures (298–403 K), pressures (0–100 MPa), and wettabilities (hydrophilic, neutral, and hydrophobic). Our results on the H2O + solid system show that vapor–solid interfacial tension should not be ignored in cases where the fluid–solid interaction energy is strong or the contact angle is close to 90°. As the temperature rises, the magnitude of H2O’s liquid–solid interfacial tension declines because the oscillation of the interfacial density/pressure profile weakens at high temperatures. However, the magnitude of H2O vapor–solid interfacial tension is enhanced with temperature due to the stronger adsorption of H2O. Moreover, the H2O–solid interfacial tension in H2O + gas (H2 or N2) + solid systems is weakly dependent on pressure, while the pressure effects on H2O–solid interfacial tensions in systems with CH4 or CO2 are significant. We show that the assumption of pressure independent H2O–solid interfacial tensions should be cautiously applied to Neumann’s method for systems containing non-hydrophilic surfaces with strong gas–solid interaction. Meanwhile, the magnitude of gas–solid interfacial tension increases with pressure and gas–solid interaction. High temperatures generally decrease the magnitude of gas–solid interfacial tensions. Further, we found that the increment of contact angle due to the presence of gases follows this order: H2 < N2 < CH4 < CO2.

We investigate the thermal phase shift in an integrated terahertz silicon effective medium waveguide at a frequency of 0.15 THz. The obtained value of the thermo-optic coefficient opens the possibility of creating thermally tunable phase shifters for future THz phased antenna arrays, which will become the basic elements of new generation communication systems with a high data transfer rate.
Borderline first-order phase transition and large cryogenic magnetocaloric effect in PrNdIn

Published: September 2023

We report a large cryogenic magnetocaloric effect stemming from an unconventional borderline first-order magnetic phase transition with negligibly small thermomagnetic hysteresis in a rare-earth-based intermetallic compound PrNdIn. The sample exhibits maximum magnetic field-induced entropy change as large as −10 J/Kg K (for 20 kOe magnetic field change) near the boiling point of oxygen. Magnetocaloric properties of PrNdIn are comparable to those of other known potential magnetocaloric materials with operating temperatures ranging between 50 and 125 K. The magnetic properties of the present sample are qualitatively reminiscent of those of the binary Pr2In and Nd2In, including the emergence of a second low-temperature anomaly in the temperature dependence of magnetization.

We study the structure of reverse shocks formed by the collision of supersonic, magnetized plasma flows driven by an inverse (or exploding) wire array with a planar conducting obstacle. We observe that the structure of these reverse shocks varies dramatically with wire material, despite the similar upstream flow velocities and mass densities. For aluminum wire arrays, the shock is sharp and well-defined, consistent with magneto-hydrodynamic theory. In contrast, we do not observe a well-defined shock using tungsten wires, and instead we see a broad region dominated by density fluctuations on a wide range of spatial scales. We diagnose these two very different interactions using interferometry, Thomson scattering, shadowgraphy, and a newly developed imaging refractometer that is sensitive to small deflections of the probing laser corresponding to small-scale density perturbations. We conclude that the differences in shock structure are most likely due to radiative cooling instabilities, which create small-scale density perturbations elongated along magnetic field lines in the tungsten plasma. These instabilities grow more slowly and are smoothed by thermal conduction in the aluminum plasma.
