Optical-parametric-oscillation-based $\chi^{(2)}$ frequency comb in a lithium niobate microresonator
, 2021 Microresonator frequency combs based on the $\chi^{(3)}$ nonlinearity are nowadays well understood and making their way into different applications. Recently, microresonator frequency combs based on the $\chi^{(2)}$ nonlinearity are receiving increasing ...

Investigation of non-uniform airflow signal oscillation during high frequency chest compression
BioMedical Engineering OnLine, 2005 Background High frequency chest compression (HFCC) is a useful and popular therapy for clearing bronchial airways of excessive or thicker mucus. Our observation of respiratory airflow of a subject during use of HFCC showed the airflow oscillation by HFCC

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer
Molecular Oncology, EarlyView.Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

High frequency oscillations and mucociliary transport
Biomedicine & Pharmacotherapy, 1989 Mucociliary transport is influenced by high frequency oscillation of air within the lungs. While some studies suggest that high frequency ventilation may be detrimental, with appropriate techniques, there is no doubt that this has potential as a means of improving the clearance of secretions from the lung.

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

High-frequency chestwall oscillation in rehabilitation of patients with COPD
Медицинский совет, 2013 Chronic obstructive pulmonary disease is a preventable and treatable disease. It is characterized by persistent airflow limitation that is usually progressive and associated with enhanced chronic inflammatory response in the airways and the lung to ...

HIGH FREQUENCY ELECTRICAL OSCILLATIONS IN CAVITIES
Mathematical Modelling and Analysis, 2018 If the interior of a conducting cavity (such as a capacitor or a coaxial cable) is supplied with a very high-frequency electric signal, the information between the walls propagates with an appreciable delay, due to the _niteness of the speed of light. The con_guration is typical of cavities having size larger than the wavelength of the injected signal.
