Multiple injection techniques to stimulate complex fracture networks in coal reservoirs: A case study on gas disaster reduction of subsurface coal mine in southwest China

open access: yesDeep Underground Science and Engineering, EarlyView.
An experimental device for physical simulation of hydraulic fracturing, comprising: a load‐bearing mechanism with multiple interconnected plates that collectively form an sample chamber; a load‐generating mechanisms, with multiple load‐generating mechanisms arranged within the experimental chamber.

Neonatal respiratory support strategies—short and long-term respiratory outcomes

open access: yesFrontiers in Pediatrics, 2023
Mechanical ventilation (MV), although life-saving, is associated with chronic respiratory morbidity in both preterm and term born infants. New ventilation modes have been developed with the aim of minimising lung injury.

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

open access: yesDeep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

THE CLASSIFICATION OF INTERMITTENT POSITIVE PRESSURE VENTILATORS

open access: yesBritish Journal of Anaesthesia, 1972
SUMMARY Minute volume, tidal volume and inspiratory flow are used as the basis for classification; for each characteristic, ventilators are divided into two groups—those that are “stable” and those that are “flexible”.

An Experimental Investigation on the Impact of Burner Height and Location on the Characteristics of Externally Venting Flames

open access: yesFire and Materials, EarlyView.
ABSTRACT Fire sources in actual compartment fires exhibit a predominantly uneven spatial distribution. In this context, the impact of the height and location of the fire source, as well as the heat release rate (HRR) of the fire, on the thermal characteristics of Externally Venting Flames (EVF) is experimentally investigated.

Safety in intrahospital transportation: evaluation of respiratory and hemodynamic parameters. A prospective cohort study

open access: yesSão Paulo Medical Journal
CONTEXT AND OBJECTIVE: Intrahospital transportation of mechanically ventilated patients is a high-risk situation. We aimed to determine whether transfers could be safely performed by using a transportation routine.

A Large‐Area, Stretchable Accelerometer Array for Spatial Assessment of Chest Compressions in Cardiopulmonary Resuscitation

open access: yesFlexTech, EarlyView.
A large‐area stretchable accelerometer array enables multi‐point monitoring of chest compression depth and thoracic contour reconstruction during CPR, offering high spatiotemporal resolution for dynamic deformation tracking and providing a new pathway toward intelligent, feedback‐based resuscitation systems. ABSTRACT High‐quality chest compressions are

Impact of Bariatric Surgery on Hypoglossal Nerve Stimulation Outcomes

open access: yesThe Laryngoscope, EarlyView.
ABSTRACT Objective The effectiveness of hypoglossal nerve stimulation (HGNS) for residual obstructive sleep apnea (OSA) in patients with prior bariatric surgery (BS) has not been previously reported. We evaluate and compare HGNS outcomes in this unique population.

Voice and Speech in Atypical Parkinsonian Disorders

open access: yesMovement Disorders Clinical Practice, EarlyView.
Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics.

Recent advances of non‐invasive sensors for smart wearable respiratory monitoring

open access: yesVIEW, EarlyView.
Respiration contains rich physiological and pathological information, making it one of the most fundamental and continuous vital signs. Respiration monitoring is a non‐invasive and simple, but incredibly powerful, tool for assessing health, managing disease, and tracking fitness.
