van den Berg, E.M. (author), Boleij, M. (author), Kuenen, J.G. (author), Kleerebezem, R. (author), van Loosdrecht, Mark C.M. (author)Denitrification and dissimilatory nitrate reduction to ammonium (DNRA) compete for nitrate in natural and engineered environments. A known important factor in this microbial competition is the ratio of available electron donor and elector acceptor, here expressed as Ac/N ratio (acetate/nitrate-nitrogen). We studied the impact of the Ac/N ratio...journal article 2016

Prest, E.I.E.D. (author), Weissbrodt, D.G. (author), Hammes, F (author), van Loosdrecht, Mark C.M. (author), Vrouwenvelder, J.S. (author)Large seasonal variations in microbial drinking water quality can occur in distribution networks, but are often not taken into account when evaluating results from short-term water sampling campaigns. Temporal dynamics in bacterial community characteristics were investigated during a two-year drinking water monitoring campaign in a full-scale...journal article 2016

de Graaf, M. (author), Sihler, Holger (author), Tilstra, Lieuwe Gijsbert (author), Stammes, Piet (author)The Ozone Monitoring Instrument (OMI) is a push-broom imaging spectrometer, observing solar radiation backscattered by the Earth's atmosphere and surface. The incoming radiation is detected using a static imaging CCD (charge-coupled device) detector array with no moving parts, as opposed to most of the previous satellite spectrometers, which...journal article 2016

Fu, Guangliang (author), Heemink, A.W. (author), Lu, S. (author), Segers, AJ (author), Weber, Konradin (author), Lin, H.X. (author)The forecast accuracy of distal volcanic ash clouds is important for providing valid aviation advice during volcanic ash eruption. However, because the distal part of volcanic ash plume is far from the volcano, the influence of eruption information on this part becomes rather indirect and uncertain, resulting in inaccurate volcanic ash forecasts...journal article 2016

(author)Organ-on-Chips (OOCs) are micro-fabricated devices which are used to culture cells in order to mimic functional units of human organs. The devices are designed to simulate the physiological environment of tissues in vivo. Cells in some types of OOCs can be stimulated in situ by electrical and/or mechanical actuators. These actuations can mimic...journal article 2016

Antolović, I.M. (author), Burri, S (author), Hoebe, RA (author), Maruyama, Yuki (author), Bruschini, C (author), Charbon-Iwasaki-Charbon, E. (author)The paper presents a camera comprising 512 × 128 pixels capable of single-photon detection and gating with a maximum frame rate of 156 kfps. The photon capture is performed through a gated single-photon avalanche diode that generates a digital pulse upon photon detection and through a digital one-bit counter. Gray levels are obtained through...journal article 2016

Hou, Y. (author), Verhagen, S. (author), Wu, J (author)Ambiguity Resolution (AR) plays a vital role in precise GNSS positioning. Correctly-fixed integer ambiguities can significantly improve the positioning solution, while incorrectly-fixed integer ambiguities can bring large positioning errors and, therefore, should be avoided. The ratio test is an extensively used test to validate the fixed...journal article 2016

Biljecki, F. (author), Arroyo Ohori, G.A.K. (author), Ledoux, H. (author), Peters, R.Y. (author), Stoter, J.E. (author)The remote estimation of a region’s population has for decades been a key application of geographic information science in demography. Most studies have used 2D data (maps, satellite imagery) to estimate population avoiding field surveys and questionnaires. As the availability of semantic 3D city models is constantly increasing, we investigate...journal article 2016

(author)The lack of understanding on the soil moisture–precipitation feedback mechanisms remains a large source of uncertainty for land–atmosphere coupled models. Previous observation-based studies on the soil moisture–precipitation feedback in Illinois have shown contradictory results. This paper extends earlier research by providing a more holistic...journal article 2016

van Turnhout, J. (author)The dielectric spectra of colloidal systems often contain a typical low frequency dispersion, which usually remains unnoticed, because of the presence of strong conduction losses. The KK relations offer a means for converting ε′ into ε″ data. This allows us to calculate conduction free ε″ spectra in which the l.f. dispersion will show up...journal article 2016

Donchyts, G. (author), Schellekens, Jaap (author), Winsemius, H.C. (author), Eisemann, E. (author), van de Giesen, N.C. (author)Accurate maps of surface water are essential for many environmental applications. Surface water maps can be generated by combining measurements from multiple sources. Precise estimation of surface water using satellite imagery remains a challenging task due to the sensor limitations, complex land cover, topography, and atmospheric conditions....journal article 2016

Isufi, E. (author), Dol, H. (author), Leus, G.J.T. (author)Flooding-based protocols are a reliable solution to deliver packets in underwater sensor networks. However, these protocols potentially involve all the nodes in the forwarding process. Thus, the performance and energy efficiency are not optimal. In this work, we propose some advances of a flooding-based protocol with the goal to improve the...journal article 2016

The Fresnel lens is fabricated by encapsulating lithographically defined vertically aligned carbon nanotube (CNT) bundles inside a polydimethyl-siloxane (PDMS) layer. The composite lens material combines the excellent optical absorption...journal article 2016
