Abstract Ocean-bottom pressure gauges of wide and dense ocean-bottom observation networks around Japan, S-net DONET, observed ocean waves caused by the Tonga eruption that started at approximately 13:00 JST (UTC + 0900) on January 15, 2022. We scrutinized waveform records arriving to evaluate their nature found two significant disturbances between 20:00 21:00 after 22:00. The first disturbance ...

Advances in theoretical ideas on how galaxies formed have not been strongly influenced by the advances in observations of what might be in the voids between the concentrations of ordinary optically selected galaxies. The theory and observations are maturing, and the search for a reconciliation offers a promising opportunity to improve our understanding of cosmic evolution. I comment on the deve...

terized by one or more fingers becoming blanched, cyanotic, and red (often in that order), upon an individual’s exposure to cold stimuli or emotional stress.1 These color changes are attributable to several factors; however, they mainly result from vasospasms of the digital arteries. The disorder occurs fairly commonly and can have a variety of other presentations, ranging from mild discomfort ...

The term white coat hypertension (WCH) was initially introduced in 1984 to describe patients who had hypertension in the office but were normotensive with ambulatory blood pressure monitoring (ABPM). At the time, WCH was simply a phenomenon with nothing known about its possible effect on the development of cardiovascular (CV) disease. Three decades later, it is apparent that hypertension in the...

1. Hand heat elimination was measured during central body heating or cooling to evaluate the sensitivity of thermoregulation in patients exhibiting Raynaud’s Phenomenon. 2. Patients with Raynaud’s Phenomenon responded to central heating and cooling very much as did normal subjects. 3. Patients with Raynaud’s Phenomenon and associated connective tissue disease do not vasodilate in the hand in re...

We revisit experimental studies performed by Ekman on dead-water (Ekman, 1904) using modern techniques in order to present new insights on this peculiar phenomenon. We extend its description to more general situations such as a three-layer fluid or a linearly stratified fluid in presence of a pycnocline, showing the robustness of dead-water phenomenon. We observe large amplitude nonlinear inter...

His companion papers spurred large amounts of research, debating changes that are requ...

SINCE the jaw-winking phenomenon was first described by Marcus Gunn (1863), many such cases with other associated findings have been reported. Falls, Krause, and Cotterman (1949) reviewed 115 cases, Simpson (1956) published a comprehensive study, and Dhir and Agarwal (1961) reported a case following ptosis surgery. This case is reported because of an associated peculiarity which does not appear...

Marcus Gunn phenomenon consists of a synkenesis between the masticatory musculature and the levator muscle of the contralateral eyelid. It is seen in patients with congenital ptosis. The phenomenon is normally unilateral, but bilateral cases are not unknown. Its exact etiology is not known. We report a case of bilateral Marcus Gunn phenomenon. The ptosis is secondary to a conflict between the o...

The cervical spine is the most common site of traumatic vertebral column injuries. Respiratory insufficiency constitutes a significant proportion of the morbidity burden and is the most common cause of mortality in these patients. In seeking to enhance our capacity to treat specifically the respiratory dysfunction following spinal cord injury, investigators have studied the "crossed phrenic phe...
