Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Complexity, Governance and Networks: Introduction to the Inaugural Issue [PDF]

open access: yes, 2014
From the introduction: 1. Yet Another Journal? Why is it necessary to publish a new journal about complexity, governance, and networks? There has been an increasing interest in complexity, governance, and network studies in recent decades.

Modelling H5N1 in Bangladesh across spatial scales: Model complexity and zoonotic transmission risk

open access: yesEpidemics, 2017
Highly pathogenic avian influenza H5N1 remains a persistent public health threat, capable of causing infection in humans with a high mortality rate while simultaneously negatively impacting the livestock industry.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Complexity analysis of spontaneous brain activity: effects of depression and antidepressant treatment [PDF]

open access: yes, 2011
Magnetoencephalography (MEG) allows the real-time recording of neural activity and oscillatory activity in distributed neural networks. We applied a non-linear complexity analysis to resting-state neural activity as measured using whole-head MEG ...

Signal detection by complex spatial filtering [PDF]

open access: yesIEEE Transactions on Information Theory, 1964
Summary: In the past, spatial filtering in coherent optical systems has been limited by the inability to realize practically a general complex filter. This paper describes a technique for realizing such a filter, and gives an application of spatial filtering to the problem of detecting isolated signals in a variety of noise backgrounds.

Smaller is better: nanobodies meet NMR

open access: yesFEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

The IH-complex of Spatial Trivalent Graphs

open access: yesTokyo Journal of Mathematics, 2010
The authors define the IH-complex on the set of spatial trivalent graphs as follows: The vertices of the complex are isotopy classes of spatial trivalent graphs, and two vertices are connected by an edge if one graph can be obtained from another by an IH-move.

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

open access: yesFEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Shopping Centre Spatial Complexity, Management Efficiency and Tenant Mix Variety [PDF]

open access: yes, 2013
Spatial complexity is not only one of the crucial sources of wayfinding problem within a shopping facility but also a significant determinant for space usage efficiency.
