FIRS: Neonatal considerations

Seminars in Fetal and Neonatal Medicine, 2020
Fetal Inflammatory Response Syndrome (FIRS) is the fetal counterpart of systemic inflammatory response syndrome (SIRS) described in adults. When the fetus is directly exposed to inflammation of the fetal membranes or the placental-fetal circulation, and organs are adversely affected, the disorder is known as FIRS. This syndrome can significantly affect

FIR-median hybrid filters with predictive FIR substructures

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1988
Median filters are especially used when processing signal which exhibit smooth behaviour with unknown switching points (e.g. blood pressure signals). They work on the basis of the so-called Standard Median (SM) filter algorithm. A better solution has been found by the introduction of finite-impulse-response (FIR) median hybrid filters (FMH) which allow

Dwarfmistletoe on Red Fir and White Fir in California

Journal of Forestry, 1963
Abstract Stands of red fir and white fir in California are extensively infected with the fir dwarfmistletoe, and damage is heavy over much of the fir belt. Field observations and cross-inoculation studies show that there are two specialized forms of fir dwarfmistletoe, one attacking only red fir and one only white fir.

Comparative Susceptibility of Corkbark Fir and Douglas-fir to Douglas-fir Dwarf Mistietoe

Forest Science, 1984
Abstract Corkbark fir (Abies lasiocarpa var. arizonica [Merriam] Lemm.) is less susceptible to infection by Douglas-fir dwarf mistletoe (Arceuthobium douglasii Engelm.) than previously reported. Infection of corkbark fir was less than 20 percent in nearly all of the mixed conifer stands sampled, regardless of the intensity of ...

Douglas-Fir Defects caused by the Douglas-Fir Beetle

Journal of Forestry, 1965
Abstract The Douglas-fir beetle is shown to cause pitch streaks in Douglas-fir. These insects are attracted to dead or dying trees but also attack nearby healthy, standing trees. Usually only a small percentage of the attacked trees are killed. The rest sustain some kind of beetle-caused defect in the form of pitch pockets or streaks.
