Noninvasive Focal Gene Delivery into the Cerebellum of Non‐Human Primates using Focused Ultrasound
Advanced Science, Volume 13, Issue 37, 3 July 2026.Focal and non‐invasive viral vector delivery in non‐human primates remains a major challenge in translational neuroscience. Low‐intensity focused ultrasound was used to transiently open the blood–brain barrier and enable targeted gene delivery to the cerebellum.

A new in silico model to precisely design focused ultrasound brain therapies
Medical Physics, Volume 53, Issue 7, July 2026.Abstract Background Focused ultrasound (FUS) combined with microbubbles enables transient and noninvasive blood–brain barrier (BBB) opening, facilitating targeted drug delivery. However, accurate treatment planning remains difficult due to inter‐patient anatomical variability and the common assumption in simulations that brain tissues behave like water.

Subharmonic almost periodic functions
, 2005 We prove that almost periodicity in the sense of distributions coincides with almost periodicity with respect to Stepanov's metric for the class of subharmonic functions in a strip {z belongs C : a < Imz < b}.

Tidal River Flood Risk Highest During Intermediate Rather Than Peak River Discharge
AGU Advances, Volume 7, Issue 3, June 2026.Abstract Tidal rivers are defined as the tide‐influenced, salinity‐free inland reaches of estuaries. Understanding the occurrence of peak water levels (PWLs) is critical for flood risk management, yet the timing and magnitude of PWLs in tidal rivers have been little studied. We address this gap by investigating PWLs during two catastrophic floods (1954

Field Observations of Intermittent Cross‐Shore Bed Load Transport on a Low‐Energy Beach
Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.Abstract Low‐energy sandy beaches typically have a rippled bed, and the presence of bed forms can strongly affect net sediment transport rates under combined forcing of waves and currents. In case low‐energetic forcing is combined with coarse sediment, bed load transport is an important mechanism to understand transport processes on such beaches.

Subharmonic spectroscopy of ultrasound contrast agents
, 2010 We have investigated the subharmonic vibration of BR14 (Bracco Research S.A., Geneva, Switzerland) contrast agent microbubbles between 8-11 MHz. The response of the bubbles is recorded optically with the ultrafast recording camera (Brandaris 128) at ...

Subharmonic functions and associated measures in ℝn
Open MathematicsFor subharmonic functions ss in Rn,n≥2,{{\mathbb{R}}}^{n},n\ge 2, there is an associated Radon measure μ\mu that is used to represent ss locally as an integral up to an additive harmonic function. We prove that the total measure μ(R2)\mu ({{\mathbb{R}}}^

Abstract and Applied Analysis, 2012 By introducing subdifferentiability of lower semicontinuous convex function φ(x(t),x(t−τ)) and its conjugate function, as well as critical point theory and operator equation theory, we obtain the existence of multiple subharmonic periodic solutions to ...

Subharmonic resonance and fixed-range asymptotic stability of the fractional-order SD oscillator
Advances in Mechanical EngineeringThe smooth and discontinuous (SD) oscillator is a typical system with strong nonlinear characteristics, and it is widely used in low-frequency vibration isolation and energy harvesting. A fractional damping model denoted by the Caputo model is introduced
