New Insights into the Controls and Mechanisms of Plankton Productivity in Coastal Upwelling Waters of the Northern California Current System
Controls and Mechanisms Plankton Productivity Coastal Upwelling Waters Northern California Current System
2015/7/22
During the lifetime of the National Science Foundation's Coastal Ocean Processes program, four experiments were conducted on the US West Coast in the northern California Current System. Although each ...
We consider mechanism design for agents who know their own ordinal preferences, but whose preferences over lotteries may be uncertain. We ask whether
this uncertainty gives a reason to use mechanisms...
Ocean Dynamics and the Carbon Cycle:Principles and Mechanisms
Ocean Dynamics Carbon Cycle Principles and Mechanisms
2015/7/15
Williams and Follows combined their expertise to write a book targeted at honors undergraduate or graduate students, as well as at professionals in ocean science who need to learn the fundamentals of ...
Determining molecular mechanisms of DNA Non-Homologous End Joining proteins
DNA repair non-homologous end joining
2015/5/25
DNA double strand breaks (DSB), particularly those induced by ionizing radiation (IR) are complex lesions and if not repaired, these breaks can lead to genomic instability, chromosomal abnormalities a...
THE MECHANISMS REGULATING THE TRANSCRIPTION FACTOR ATF5 AND ITS FUNCTION IN THE INTEGRATED STRESS RESPONSE
ATF5 stress uORF
2015/5/25
Phosphorylation of eukaryotic initiation factor 2 (eIF2) is an important mechanism regulating global and gene-specific translation during different environmental stresses. Repressed global translation...
Mechanisms of recruitment of the CTD phosphatase Rtr1 to RNA polymerase II
Rtr1 RNA polymerase II transcription
2015/5/25
The C-terminal domain (CTD) of the RNA polymerase II (RNAPII) subunit Rpb1 must exist in a hypophosphorylated state prior to forming a competent transcription initiation complex. However, during trans...
Mechanisms of binding diversity in protein disorder : molecular recognition features mediating protein interaction networks
Many-to-one binding Partner selection MoRF
2015/5/25
Intrinsically disordered proteins are proteins characterized by lack of stable tertiary structures under physiological conditions. Evidence shows that disordered proteins are not only highly involved ...
Signaling mechanisms that suppress the anabolic response of osteoblasts and osteocytes to fluid shear stress
Mechanotransduction Osteoblast Osteocyte
2015/5/22
Bone is a dynamic organ that responds to its external environment. Cell signaling cascades are initiated within bone cells when changes in mechanical loading occur. To describe these molecular signali...
Distribution and supply mechanisms of high uranium concentration in the rivers of Okinawa Island, Japan
uranium river Okinawa Island guideline value supply mechanism
2017/4/10
Uranium concentrations in the rivers of Okinawa Island, Japan were determined in this study. Most rivers in the
southwestern area of the island showed high U concentrations, the highest of which was ...
Stochastic Quantification of Missing Mechanisms in Dynamical Systems
ynamical Systems Missing Mechanisms
2015/4/3
Due to lack of knowledge:
Missing mechanisms (ignored “too small" or “too fast" or
“unimportant" processes)
Unresolved scales (not represented in models)
Model uncertainties
Mechanisms of Fe(III) oxide reduction in the environment and in pure culture
Soil sediment microbes oxide minerals
2015/1/28
The reduction of Fe(III) is one of the most significant reactions that takes place as anaerobic conditions develop in soils and sediments. The mechanisms by which Fe(III) is reduced in sediment and by...
Focal mechanisms in the southern Aegean from temporary seismic networks – implications for the regional stress field and ongoing deformation processes
Focal mechanisms the southern Aegean temporary seismic networks the regional stress field ongoing deformation processes
2015/1/6
The lateral variation of the stress field in the southern Aegean plate and the subducting Hellenic slab is determined from recordings of seismicity obtained with the CYCNET and EGELADOS networks in th...
Exhumation of (ultra-)high-pressure terranes: concepts and mechanisms
Ultra-high pressure crustal rocks in phanerozoic continental plate subduction collision events
2015/1/5
The formation and exhumation of high and ultra-high-pressure, (U)HP, rocks of crustal origin appears to be ubiquitous during Phanerozoic plate subduction and continental collision events. Exhumation o...
Entrainment Mechanisms for Outflows in the L1551 Star-Forming Region
L1551 IRS5 formation
2014/12/24
We present high sensitivity 12CO and 13CO J=1!0 molecular line maps covering the full extent of the parsec scale L1551 molecular outflow, including the redshifted east-west (EW) flow. We also present ...
The fine-tuning problems of particle physics and anthropic mechanisms
Particle physics the multiverse fine-tuning the multiverse
2014/12/20
Many of the classic problems of particle physics appear in a very different light when viewed from the perspective of the multiverse. Most importantly the two great ``fine tuning'' problems that motiv...
