Temporal Variation of Moose–Vehicle Collisions in Alaska

open access: yesHuman-Wildlife Interactions, 2020
Collisions between vehicles and wildlife have long been recognized to pose threats to motorists and wildlife populations. In addition to the risk of injury or mortality faced by the motorists involved in wildlife-vehicle collisions (WVCs), other drivers ...

About Russian Alaska and Its Ruler A.A. Baranov

open access: yesАрктика и Север, 2021
The purpose of this study is to analyze the present and past of the history of Alaska. Such a combination of times highlighted the most difficult problem of ambiguous attitude to the historical past in the USA from the standpoint of modernity.

Proposal for midinfrared light--induced ferroelectricity in oxide paraelectrics [PDF]

open access: yesPhys. Rev. B 95, 134113 (2017), 2016
I show that a nonequilibrium paraelectric to ferroelectric transition can be induced using midinfrared pulses. This relies on a quartic $lQ_{\textrm{l$_z$}}^2Q_{\textrm{h$_x$}}^2$ coupling between the lowest ($Q_{\textrm{l$_z$}}$) and highest ($Q_{\textrm{h$_x$}}$) frequency infrared-active phonon modes of a paraelectric material.

Possible role of human ribonuclease dicer in the regulation of R loops

open access: yesFEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

The last deglaciation of Alaska

open access: yesCuadernos de Investigación Geográfica, 2017
We review available chronologies that constrain the timing of glacier fluctuations during the last deglaciation in Alaska. We address three questions relating to the last glacial termination: (i) How did the timing of glacier recession relate to buildup ...

A bitter taste of fish: the temporality of salmon, settler colonialism, and the work of well-being in a Yupiaq fishing village

open access: yesEcology and Society, 2020
In southwest Alaska, dominant narratives of subsistence and conservation are concerned predominantly with material relations with fish, with the number of fish that are killed. In Akiak, an Alaska Native (Yupiaq) village located along the Kuskokwim River,

Ionizing wave via high-power HF acceleration [PDF]

open access: yes, 2010
Recent ionospheric modification experiments with the 3.6 MW transmitter at the High Frequency Active Auroral Research Program (HAARP) facility in Alaska led to discovery of artificial ionization descending from the nominal interaction altitude in the background F-region ionosphere by ~60 km. This paper presents a physical model of an ionizing wavefront

Proposal for ultrafast switching of ferroelectrics using mid-infrared pulses [PDF]

open access: yesPhys. Rev. B 92, 214303 (2015), 2015
I propose a method for ultrafast switching of ferroelectric polarization using mid-infrared pulses. This involves selectively exciting the highest frequency $A_1$ phonon mode of a ferroelectric material with an intense mid-infrared pulse. Large amplitude oscillations of this mode provides a unidirectional force to the lattice such that it displaces ...

Radio in Alaska [PDF]

open access: yesProceedings of the IRE, 1916
The chain of semi-high-power stations (25 K.W.) established by the Marconi Company at Ketchikan, Juneau, and Astoria in Alaska are described. The masts, insulation, antenna, power supply, rotary converter, discharger, and relay key of these stations are considered in detail. The climatic and radio stray conditions are shown to be unusual.

Enhanced discovery of bacterial laccase‐like multicopper oxidase through computer simulation and metagenomic analysis of industrial wastewater

open access: yesFEBS Open Bio, EarlyView.
We obtained potential bacterial laccase‐like multicopper oxidase (LMCO) sequences through metagenomic sequencing. All sequences exhibited significant differences from known LMCOs in databases. To select the most promising candidates, we performed structure prediction and molecular docking using alphafold2, metal3d and rosetta.
