FFTPL: An Analytic Placement Algorithm Using Fast Fourier Transform for Density Equalization [PDF]

open access: yes, 2013
We propose a flat nonlinear placement algorithm FFTPL using fast Fourier transform for density equalization. The placement instance is modeled as an electrostatic system with the analogy of density cost to the potential energy.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Kraški rob (landscape term) Geologic section along the motorway Kozina – Koper (Capodistria)

open access: yesGeologija, 2007
Geologic section along the motorway from Kozina to Koper in totality exposed geologic structure of the border belt between Adriatic-Apulian foreland and Dinarides that was formed by subthrusting of Adriatic-Apulian foreland (Istria, Friuli) underneath ...

A Proposition for Geodetic Recording of Active Fault Zones [PDF]

open access: yes, 2007
Establishing recent displacements along faults is an important and delicate task. Larger\ud faults are accompanied by broader fault zones that require a specific approach to geodetic\ud measurements of fault block displacements. The vector of fault block

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Managing in situ gold concentrations in placers [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2015
In studying of the in situ gravitational concentration process part feature for placer, the technological ability to transform the in situ massif placer structure is evident.

Ghosts, Words, Memories and Stories in Katherine Anne Porter’s “Old Mortality” and Sandra Cisneros’s The House on Mango Street [PDF]

open access: yes, 2008
[Abstract] Katherine Anne Porter was born in 1890 and she published “Old Mortality” in 1937; she was an acclaimed writer of short stories when Sandra Cisneros was born in 1954, and she had been dead for more than ten years when the latter first published

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Natural revegetation of placer mined lands of interior Alaska II [PDF]

open access: yes, 1980
To the uninitiated eye an aerial photo of Fairbanks’ surrounding area includes patches of what might appear to be the channels left by the workings of a bark beetle grub.
