The impact of neurosurgical procedure on cognitive resources: Results of bypass training.

Surgical neurology international

Huotarinen A, Niemelä M, Hafez A.
PMID: 29721350
Surg Neurol Int. 2018 Apr 05;9:71. doi: 10.4103/sni.sni_427_17. eCollection 2018.

BACKGROUND: Neurosurgeons are exposed to unavoidable distractions in their natural operating environment. Distractions can affect both the surgeon's concentration and the safety and duration of the surgery. Such distraction can be studied by applying a simultaneous cognitive task during...

The influence of ants on the survival of mountain birches during an Oporinia autumnata (Lep., Geometridae) outbreak.

Laine KJ, Niemelä P.
PMID: 28309626
Oecologia. 1980 Jan;47(1):39-42. doi: 10.1007/BF00541773.

The present study reports the influence of ants on the survival of mountain birch (Betula pubescens ssp. tortuosa) during an Oporinia autumnata (Lep., Geometridae) outbreak. Undamaged "green islands" with a radius of 15-20 m were observed around Formica aquilonia...

Foliage phenols and nitrogen in relation to growth, insect damage, and ability to recover after defoliation, in the mountain birch Betula pubescens ssp tortuosa.

Haukioja E, Niemelä P, Sirén S.
PMID: 28310668
Oecologia. 1985 Jan;65(2):214-222. doi: 10.1007/BF00379220.

We studied growth of the mountain birch, and the role of foliage phenols, nitrogen, and variance in the timing of bud burst, as potential defensive characters, in Finnish Lapland in 1975-1979. Annual and local variation both in phenol and...

Gene flow from domesticated escapes alters the life history of wild Atlantic salmon.

Nature ecology & evolution

Bolstad GH, Hindar K, Robertsen G, Jonsson B, Sægrov H, Diserud OH, Fiske P, Jensen AJ, Urdal K, Næsje TF, Barlaup BT, Florø-Larsen B, Lo H, Niemelä E, Karlsson S.

Nat Ecol Evol. 2017 Apr 10;1(5):124. doi: 10.1038/s41559-017-0124.

Interbreeding between domesticated and wild animals occurs in several species. This gene flow has long been anticipated to induce genetic changes in life-history traits of wild populations, thereby influencing population dynamics and viability. Here, we show that individuals with...

Rev Sci Instrum. 2019 Sep;90(9):093002. doi: 10.1063/1.5115105.

We present the design of a Cr:forsterite based single-frequency master-oscillator power-amplifier laser system delivering much higher output energy compared to previous literature reports. The system has four amplifying stages with two-pass configuration each, thus enabling the generation of 24...
