Dynamic cracking properties and generating conditions of coal under rapid gas release

Deep Underground Science and Engineering, EarlyView.
Gas release tests revealed that crack initiation and propagation are jointly controlled by initial crack length, residual strength, and gas release velocity. A new outburst risk coefficient was thus developed from a fracture mechanics perspective, offering a novel predictive approach.

Clinical impact of magnetic resonance imaging distortions on gamma knife radiosurgery

Journal of Medical Radiation Sciences, 2021
Introduction Magnetic resonance imaging (MRI) is the preferred imaging modality for Leksell Gamma Knife® (LGK) stereotactic radiosurgery (SRS) treatment planning (TP) due to superior soft tissue definition compared to computed tomography (CT).

Targeted next-generation sequencing of dedifferentiated chondrosarcoma in the skull base reveals combined TP53 and PTEN mutations with increased proliferation index, an implication for pathogenesis [PDF]

, 2016
Dedifferentiated chondrosarcoma (DDCS) is a rare disease with a dismal prognosis. DDCS consists of two morphologically distinct components: the cartilaginous and noncartilaginous components.

Postictal self‐removal of intracerebral electrodes during stereoelectroencephalography monitoring: A case series

Epileptic Disorders, EarlyView.
Abstract Epilepsy surgery remains the most effective treatment for focal drug‐resistant epilepsy, and stereoelectroencephalography (SEEG) is increasingly used to define the epileptogenic‐zone network (EZN) and guide curative or palliative interventions.

Gamma Knife Radiosurgery.

Seminars in radiation oncology
The concept of radiosurgery and its requirements are presented. Dedicated radiosurgical tools include the modified linear accelerators working with a single rotating beam and the Gamma Knife with multiple stationary radiation sources. The 201 gamma beams from the cobalt 60 sources of the Gamma Knife intersect within 0.3 mm and it is possible to align ...

A real-time optimal inverse planning for Gamma Knife radiosurgery by convex optimization: description of the system and first dosimetry data.

Journal of Neurosurgery, 2018
OBJECTIVEThe authors developed a new, real-time interactive inverse planning approach, based on a fully convex framework, to be used for Gamma Knife radiosurgery.METHODSThe convex framework is based on the precomputation of a dictionary composed of the ...

Synchrotron‐generated microbeams as a radiosurgical alternative for drug‐resistant epilepsies: Proof of concept in a mouse model of mesiotemporal lobe epilepsy

Epilepsia, EarlyView.
Abstract Objective One‐third of patients with epilepsy, particularly those with mesial temporal lobe epilepsy (MTLE), remain resistant to medication. Resective surgery, the gold standard, is highly invasive and carries significant risks. Here, using a mouse model, we explored the potential of microbeam radiation therapy (MRT), a new technique based on ...

A retrospective analysis of survival and prognostic factors after stereotactic radiosurgery for aggressive meningiomas [PDF]

, 2014
BACKGROUND: While most meningiomas are benign, aggressive meningiomas are associated with high levels of recurrence and mortality. A single institution’s Gamma Knife radiosurgical experience with atypical and malignant meningiomas is presented ...

Seizure control after radiosurgical treatment in patients with cerebral arteriovenous malformations: An observational study

Epilepsia, EarlyView.
Abstract Objective Seizures are among the most common symptoms of cerebral arteriovenous malformations (AVMs). Although the main goal of AVM treatment remains complete obliteration, seizure control has become an important treatment aspect in recent years.
