Smartcard Integration with Kerberos V5 [PDF]

open access: yes, 1998
We describe our design and implementation of smartcard integration with Kerberos V5. Authentication is among the most important applications for smartcards and is one of the critical requirements for computer security.

How to Navigate in Different Environments and Situations: Lessons From Ants

open access: yesFrontiers in Psychology, 2018
Ants are a globally distributed insect family whose members have adapted to live in a wide range of different environments and ecological niches. Foraging ants everywhere face the recurring challenge of navigating to find food and to bring it back to the

Directed evolution of enzymes at the crossroads of tradition and innovation

open access: yesFEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

A time-stamp mechanism may provide temporal information necessary for egocentric to allocentric spatial transformations

open access: yeseLife, 2018
Learning the spatial organization of the environment is essential for most animals’ survival. This requires the animal to derive allocentric spatial information from egocentric sensory and motor experience.

Developing Conceptualizations of Europeanization and European Integration: Mixing Methodologies [PDF]

open access: yes, 2002
In its most explicit form Europeanization is conceptualized as the process of downloading European Union (EU) directives, regulations and institutional structures to the domestic level. However, this conceptualization of Europeanization has been extended

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education

open access: yesFEBS Open Bio, EarlyView.
Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐

Resting State Connectivity Between Medial Temporal Lobe Regions and Intrinsic Cortical Networks Predicts Performance in a Path Integration Task

open access: yesFrontiers in Human Neuroscience, 2018
Humans differ in their individual navigational performance, in part because successful navigation relies on several diverse abilities. One such navigational capability is path integration, the updating of position and orientation during movement ...

Effects of visual inputs on neural dynamics for coding of location and running speed in medial entorhinal cortex

open access: yeseLife, 2020
Neuronal representations of spatial location and movement speed in the medial entorhinal cortex during the ‘active’ theta state of the brain are important for memory-guided navigation and rely on visual inputs.

A new flow chip in combination with multiphoton microscopy as a protocol for longitudinal 3D imaging of tissue calcification under shear stress

open access: yesFEBS Open Bio, EarlyView.
Miniaturized flow chip platform enabling continuous perfusion and longitudinal multiphoton 3D imaging of vascular smooth muscle cell constructs under physiological flow. Brightfield imaging guides region selection, while CellTracker Green and mRuby‐labeled fetuin‐A visualize cells and mineral deposition, respectively. Magnesium supplementation markedly

Visual landmarks sharpen grid cell metric and confer context specificity to neurons of the medial entorhinal cortex

open access: yeseLife, 2016
Neurons of the medial entorhinal cortex (MEC) provide spatial representations critical for navigation. In this network, the periodic firing fields of grid cells act as a metric element for position.
