Investigating the sonosphere can serve as a valuable proxy for understanding various ecosystem processes. Consequently, an ecoacoustic perspective broadens our capacity to understand how airborne sounds interact along an ecotone at the soil surface with the subterranean sounds generated within a pedon. We explored techniques that could detect, quantify, and analyze the sonic dimensions of a sonosphere in the form of sounds within a unit of soil (sonopedon), sounds from a landscape unit (sonotope), and the sonic ecotone (sonotone) where these phenomena converge. We recorded sounds for 24 h over 20 days in September 2024 at 40 sites distributed evenly across a small rural parcel of agricultural land in Northern Italy. We utilized a sound recording device fabricated with a sonic probe that simultaneously operated inside the soil and the grounds’ surface, which successfully captured sounds attributable both to the soilscape and to the landscape. We calculated the Sonic Heterogeneity Indices, SHItf and SHIft, and analyzed the Spectral and Temporal Sonic Signatures along with Spectral Sonic Variability, Effective Number of Frequency Bins, and Sonic Dissimilarity. Each calculation contributed to a detailed description of how the sonosphere is characterized across the frequency spectrum, temporal dynamics, and sound sources. The sonosphere in our study area, primarily characterized by the low-frequency spectra, possessed a mix of biological, geophysical, and anthropogenic sounds displaying distinct temporal patterns (sonophases) that coincided with astronomic divisions of the day (daytime, twilights, and nighttime).

Valleytronics — exploiting a system’s pseudospin degree of freedom — is being increasingly explored in sonic crystals. Now, valley transport of sound is reported for a macroscopic triangular-lattice array of rod-like scatterers in a 2D air waveguide. The concept of valley pseudospin, labelling quantum states of energy extrema in momentum space, is attracting attention 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 because of its potential as a new type of information carrier. Compared with the non-topological bulk valley transport, realized soon after predictions 1 , 2 , 3 , 4 , 5 , topological valley transport in domain walls 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 is extremely challenging owing to the inter-valley scattering inevitably induced by atomic-scale imperfections—but an electronic signature was recently observed in bilayer graphene 12 , 13 . Here, we report the experimental observation of topological valley transport of sound in sonic crystals. The macroscopic nature of sonic crystals permits a flexible and accurate design of domain walls. In addition to a direct visualization of the valley-selective edge modes through spatial scanning of the sound field, reflection immunity is observed in sharply curved interfaces. The topologically protected interface transport of sound, strikingly different from that in traditional sound waveguides 14 , 15 , may serve as the basis for designing devices with unconventional functions.

The main topics of the paper are the (non)ecological dimensions of sonic and other environments in contemporary world reflecting the “suchness” and quality of certain cultures and society of global transcapitalism in its late phase of digitalisation, and devastation as well. Various social discursive and nondiscursive practices of this civilization influence very deeply our ways of living in many important dimensions—spiritual, moral, ecological, economic, political, and way of communication among others, which is mirrored in different sonic (and other) environments we are situated. The author refers to the special works of arts, kind of new musical discourses appropriating field recordings of unique environments, sonic sculptures, or intermedia installations in social-critical contexts as the testimonies of such artists as Bob Ostertag (USA), Peter Machajdík, Jonáš Gruska (both SK), among others.

Compressional sonic logs is one of the important logs for subsurface characterization, reservoir evaluation, and wellbore stability analysis. However, acquiring these logs is often challenging due to logistical constraints. This study explores the application of machine learning (ML) techniques to predict compressional sonic logs using conventional well logs from five wells. The methodology involves data preprocessing, feature selection, and training various regression models, including Random Forest, CatBoost, XGBoost, K-Nearest Neighbors (KNN), Support Vector Machines (SVM), and Deep Neural Networks (DNN). Model performance is optimized through hyperparameter tuning and evaluated using correlation coefficients and root mean square error (RMSE) metrics. Results indicate that ensemble models (Random Forest, CatBoost, XGBoost) achieve the highest accuracy, with correlation coefficients ranging from 89 to 89.6% and RMSE between 5.85 and 6.03. Additionally, feature engineering and data cleaning significantly improve model performance, while input scaling is essential for SVM, KNN, and DNN models. Incorporating blind well testing further enhances reliability. This study presents a robust ML-based workflow for predicting compressional sonic logs, offering a cost-effective solution for reservoir management and geomechanical analysis.

Monitoring respiratory characteristics is an important method to monitor sleep respiratory diseases such as obstructive sleep apnea syndrome (OSAS). In this letter, a passive wireless respiratory sensor is developed, which is based on a surface acoustic wave (SAW) microsensor using graphene oxide as a sensitive layer. The developed sensor is placed on the upper lip below the nose, which monitors human's breathing by detecting the humidity changes while inhale and exhale. To meet the fast response requirement of human respiratory, the effect of the thicknesses of graphene oxide (GO) films is investigated. Results show that the response and recovery time of the sensor can achieve 0.4 and 1.4 s, respectively, with the optimized 70‐nm thickness of GO. The respiratory rate that the sensing system can measure is greater than 33 breaths per minute, outcompeting the average number of breaths per minute from an adult (i.e. 16–20 breaths per minute). The new sensor proposed here paves the way for the fabrication of high‐performance and low‐cost respiratory sensors in human breathing monitoring in real life.

Pancreatic cancer is one of the leading causes of cancer-related death in the United States and survival outcomes remain dismal despite significant advances in molecular diagnostics and therapeutics in clinical practice. The microenvironment of pancreatic cancer carries unique features with increased desmoplastic reaction and is infiltrated by regulatory T cells and myeloid-derived suppressor cells which negatively impact the effector immune cells. Current evidence suggests that stellate cell-induced hypovascular stroma may have direct effects on aggressive behavior of pancreatic cancer. Preclinical studies suggested improvement in drug delivery to cancer cells with stroma modifying agents. However these findings so far have not been confirmed in clinical trials. In this article, we elaborate current-state-of-the science of the pancreatic cancer microenvironment and its impact on molecular behavior of cancer cells, chemotherapy resistance and druggability of stroma elements in combination with other agents to enhance the efficacy of therapeutic approaches.

Based on Wagner’s thorough knowledge of Mendelssohn’s Hebriden-Overture, parallels between his works and Mendelssohn’s overture with respect to the organization of sonorites are identified: systematic ones, where a decrease in motivic development shifts the listener’s attention to sonority, causing traditional forms to become blurred, creating thereby new ones due to various applications of sonic layers; and, conversely, where the shift to sonority gives rise to occasional similarities, in that both composers present themselves in dramaturgical climaxes that are realized through developmental techniques that gradually lead to a fusion of previously fluctuating layers. This technique, however, is dependent on both composers’ differing relationship to traditional formal schemes and how this relates to their disparate degrees of expression and continuity of musical thought.

Research into the geographies of sound and music has developed over the last 20 years, yet such work largely remains reliant on conventional verbal-textual methods of data collection and dissemination. In this paper, we conduct a review of current approaches to sonic research, demonstrating that the erasure of audio media within geography silences a rich seam of empirical data. As a result, we propose that phonographic methods – including listening, audio recording and playback – need to be developed further. We consider a range of epistemological implications of phonographic methods, and possible future directions for their development in human geography.

The main goal of this article is to combine, within the context of sonic warfare, the concepts of soundscape (R. Murray Schafer), narrativity (Algirdas Greimas), and sonic warfare continuum (Steve Goodman), all interpreted through the lens of the resonance theory as postulated by Hartmut Rosa. The thesis is that resonance, as an unstoppable and affective force that can be exerted on (and by) all physical objects, contains a dangerous component that can be identified in so-called “sonic weapons” and “sonic war machines”. By identifying specific soundscapes and analyzing different sonic weapons, it becomes possible to use the sonic warfare continuum to study the resonance they establish with listeners, and one can also conceive different effects and inclinations towards the same “resonating” objects. To illustrate this theoretical framework, two recordings of Rudyard Kipling’s poem and their reception in different contexts and soundscapes will be analyzed. This will demonstrate how, within the sonic warfare continuum, different narratives surrounding sonic war machines push the listeners to react to similar stimulations. Therefore, listeners establish resonance through sonic war machines in powerful, tensive, and potentially threatening ways.
