Spontaneous deracemizations is a challenging, multidisciplinary subject in current chirality research. In the absence of any chiral inductors, an achiral substance or a racemic composition is driven into an enantioenriched or even homochiral state through a selective energy input, e.g., chemical potential, photoirradiation, mechanical grinding ...

Spontaneous Pancreatitis in Spontaneously Hypertensive Rats
Pancreas, 1994The pancreatic lesions in 6- to 36-week-old spontaneously hypertensive rats (SHR), stroke prone SHR (SHRSP) and Wistar-Kyoto rats (WKY) were examined histopathologically. Inflammatory cell infiltration with hemorrhage and stromal fibrosis became evident in 12-week-old SHR and SHRSP together with acinar atrophy and/or degeneration and ductular ...

Separation of non-spontaneous and spontaneous speech
Proceedings of the 1998 IEEE International Conference on Acoustics, Speech and Signal Processing, ICASSP '98 (Cat. No.98CH36181), 2002There are many situations in which it is desirable to be able to distinguish spontaneous speech and speech which is non-spontaneous. Examples of situations in which this problem may arise include forensic evidence situations, sorting voice-mail responses from voice-mail menus, and automatic segmentation of spontaneous responses from prepared questions.

A case of spontaneous pneumomediastinum with cervical emphysema is reported. Spontaneous pneumomediastinum may complicate processes that decrease pulmonary interstitial pressure or increase intraalveolar pressure leading to alveolar rupture. Free air may then tract along blood vessels and decompress into the soft tissues of the neck.

Primary Care: Clinics in Office Practice, 1993
Spontaneous abortion rates vary with maternal age, but the overall incidence is approximately 2% of clinically recognized pregnancies. The incidence of clinically unrecognized loss is approximately 20%. Most early fetal losses are caused by abnormal karyotypes.

How can we increase the capillarity of the Net without facing the daunting issues that come with large-scale infrastructures? Can we embed all necessary protocols into our terminals and then use the terminals themselves to relay packets? This chapter develops the vision of ubiquitous connectivity, pinpointing foundations and problems.

Spontaneous pyopneumopericardium
The American Journal of Emergency Medicine, 1999A previously healthy 42-year-old man presented to the emergency department with progressive weakness, lightheadedness, nausea, and lower extremity edema. Evaluation revealed hypotension, pulsus paradoxus, leukocytosis, hepatic and renal dysfunction, and an air-fluid level in the mediastinum.

ACM SIGGRAPH 2013 Computer Animation Festival, 2013
J-Walt Adamczyk pushes the envelope of animation and visual creation as a performing art with new physical and software interfaces. At SIGGRAPH 2013, he performs a new piece in which he creates and explores an improvised 3D world, taking the audience on an immersive visual-musical odyssey.

ABSTRACT. Spontaneous pneumomediastinum (SPM) is a rare entity in which free air is found within the mediastinum usually as a complication of respiratory diseases and conditions associated with increased intra‐alveolar pressure. We report a case of unusual asymptomatic SPM caused by an attack of asthma.
