Systematic multi-scale decomposition of ocean variability using machine learning.

Multi-scale systems, such as the climate system, the atmosphere, and the ocean, are hard to understand and predict due to their intrinsic nonlinearities and chaotic behavior. Here, we apply a physics-consistent machine learning method, the multi-resolution dynamic mode decomposition (mrDMD), to oceanographic data. mrDMD allows a systematic decomposition of high-dimensional data sets into time-scale dependent modes of variability.

Uncertainty quantification and sensitivity analysis of COVID-19 exit strategies in an individual-based transmission model.

Many countries are currently dealing with the COVID-19 epidemic and are searching for an exit strategy such that life in society can return to normal. To support this search, computational models are used to predict the spread of the virus and to assess the efficacy of policy measures before actual implementation. The model output has to be interpreted carefully though, as computational models are subject to uncertainties.

Full vestibular approach in pre-prosthetic surgery: retrospective evaluation of 90 patients and literature review.

Atrophy of the jaws could represent a challenge in maxillofacial and oral surgery. The correction of bone defects due to the atrophic process is frequently achieved by means of onlay bone grafting. In the present note, a technique of flap designing to approach the alveolar atrophic crest will be discussed.

The use of sensory action potential to evaluate inferior alveolar nerve damage after orthognathic surgery.

To assess and monitor the common event of neurosensory disturbance to the inferior alveolar nerve (IAN) after bilateral sagittal split osteotomy, we used clinical sensory tests and neurophysiologic test sensory action potentials. The diagnostic value of these tests was evaluated by comparing them with the degree of nerve damage reported by patients. Fourteen patients undergoing bilateral sagittal split osteotomy were analyzed preoperatively and 2 years postoperatively.

Complications of orthognathic surgery: the inferior alveolar nerve.

This study analyzes permanent paresthetic disorders regarding the inferior alveolar nerve (IAN) after mandibular ramus sagittal osteotomy procedures. Fifty patients (ie, 100 nerves) who underwent mandibular bilateral sagittal split osteotomy between 2003 and 2007 were evaluated to detect sensorial disorders of the IAN. The evaluation was performed for each patient at least 1 year after surgical intervention.
