A recent study has assessed how the choice and cultivation of native and introduced pine tree species affects the impact of insect pests and fungal diseases in Spanish plantations. Native maritime pine trees appeared to be more susceptible to insect attack, whilst non-native Monterey pines were more likely to suffer from fungal attacks. Thinning trees also had differing effects on reducing the effects of pests, depending on the tree species.

In this paper, we present a novel method for line artefacts quantification in lung ultrasound (LUS) images of COVID-19 patients. We formulate this as a non-convex regularisation problem involving a sparsity-enforcing, Cauchy-based penalty function, and the inverse Radon transform. We employ a simple local maxima detection technique in the Radon transform domain, associated with known clinical definitions of line artefacts. Despite being non-convex, the proposed method has guaranteed convergence via a proximal splitting algorithm and accurately identifies both horizontal and vertical line artefacts in LUS images. In order to reduce the number of false and missed detection, our method includes a two-stage validation mechanism, which is performed in both Radon and image domains. We evaluate the performance of the proposed method in comparison to the current state-of-the-art B-line identification method and show a considerable performance gain with 87% correctly detected B-lines in LUS images of nine COVID-19 patients. In addition, owing to its fast convergence, which takes around 12 seconds for a given frame, our proposed method is readily applicable for processing LUS image sequences.

Described is a method to prepare wet foams exhibiting long-term stability wherein colloidal particles are used to stabilize the gas-liquid interface, said particles being initially inherently partially lyophobic particles or partially lyophobized particles having mean particle sizes from 1 nm to 20 μm. In one aspect, the partially lyophobized particles are prepared in-situ by treating initially hydrophilic particles with amphiphilic molecules of specific solubility in the liquid phase of the suspension.

Provided are a three-dimensional (3D) ultrasound system and a method for operating the 3D ultrasound system, which are capable of intuitively displaying the abnormality of an object by determining a grade by comparing measurement data obtained by measuring ultrasound data relating to the object and displaying the measurement data in a different way based on the determined grade.

A method and system uniquely capable of generating thermal bubbles for improved ultrasound imaging and therapy. Several embodiments of the method and system contemplates the use of unfocused, focused, or defocused acoustic energy at variable spatial and/or temporal energy settings, in the range of about 1 kHz-100 MHz, and at variable tissue depths. The unique ability to customize acoustic energy output and target a particular region of interest makes possible highly accurate and precise thermal bubble formation. In an embodiment, the energy is acoustic energy. In other embodiments, the energy is photon based energy (e.g., IPL, LED, laser, white light, etc.), or other energy forms, such radio frequency electric currents (including monopolar and bipolar radio-frequency current). In an embodiment, the energy is various combinations of acoustic energy, electromagnetic energy and other energy forms or energy absorbers such as cooling.

A method and devices comprise a low frequency high energy ultrasound system having at least one sonotrode projecting into a reactor vessel through which the liquid passes via at least one inlet orifice and at least one outlet orifice. To avoid cavitation at the sonotrode, in a close region of the oscillation-transducing sonotrode surface a pressure/amplitude combination close to or above the pressure-amplitude characteristic line is generated at which considerably reduced or no cavitation occurs and in the adjacent region in the vessel at least in a region and at least at times a pressure/amplitude combination is maintained below the pressure-amplitude characteristic line at which cavitation is generated. A device has an inlet orifice arranged such that the liquid impacts directly onto the oscillation-transducing sonotrode surface, and is shaped that in the close region of the oscillation-transducing sonotrode surface a pressure close to or above the pressure-amplitude characteristic line prevails.
