T HE RELATIONSHIP between oxygen tension and the sickling phenomenon has been recognized for over 45 years’ and has become central to our thinking about sickle cell disease. It has been emphasized that sickling of red cells depends to a large degree upon the absolute concentration of reduced sickle hemoglobin.2 In the past two decades many therapeutic strategies have been explored in the manage...

The chromatic content (saturation) of monochromatic stimuli (480, 505, 577, and 650 nm) was scaled as a function of field size at three different retinal locations by 58 observers ranging from 18 to 83 yr of age. The different retinal locations (6 deg nasal, 2.5 deg inferior and 6 deg temporal eccentricity) were chosen according to anatomical studies demonstrating different degrees of senescent...

Coral reefs are essential to many nations, and are currently in global decline. Although climate models predict decreases in seawater pH (∼0.3 units) and oxygen saturation (∼5 percentage points), these are exceeded by the current daily pH and oxygen fluctuations on many reefs (pH 7.8-8.7 and 27-241% O2 saturation). We investigated the effect of oxygen and pH fluctuations on coral calcification ...

In recent years, oxygen targeting has become a relevant topic in neonatal intensive care medicine.1 Despite large SpO2 targeting trials including numerous subjects and the available results of a meta-analysis of these data,2,3 there is still an ongoing debate on the optimum SpO2 target range in preterm infants. Both conditions, hyperoxia as well as hypoxia, frequently occur in extremely low bir...

Expanding upon work by Diessel & Tomasello (2005, hereafter D&T) and Gries (to appear), 1 this study explores particle positioning in child language as a gradual cognitive-pragmatic development based on statistical distribution of input. The phenomenon of particle position alternation is peculiar insofar as it defines a category of combinations which show syntactic variation without concomitant...

OLAP cubes are a powerful database technology to join tables and aggregate data to discover interesting trends. However, OLAP cubes exhibit limitations to uncover fractional relationships on a measure aggregated at multiple granularity levels. One prominent example is the percentage, an intuitive probablistic metric, used in practically every analytic application. With such motivation in mind, ...

`gym-saturation` is an OpenAI Gym environment for reinforcement learning (RL) agents capable of proving theorems. Currently, only theorems written in a formal language the Thousands Problems Theorem Provers (TPTP) library clausal normal form (CNF) are supported. implements 'given clause' algorithm (similar to one used Vampire and E Prover). Being Python, was inspired by PyRes. In contrast monol...

a periodic increase in blood pressure (bp) occurs during apneic episodes in patients with obstructive sleep apnea (osa). several factors including hypoxemia and an increase in heart rate (hr) were reported to be responsible for this increased bp. to examine the contribution of these two factors in increasing bp, 35 healthy male subjects (mean age±sd= 23.64±3.80) were studied in three experiment...
