The Danish-Greek excavations at Kalydon, Aitolia: the theatre. Preliminary report from the 2011 and 2012 campaigns
In the summer of 2011 the Danish–Greek excavations atKalydon entered a new phase with the Ancient Theatreof Kalydon Project. The project, which is a synergasiabetween the 36th Ephorate of Prehistoric and ClassicalAntiquities in Mesolonghi and the Danish Institute atAthens, aims at a total excavation of the theatre of Kalydonover three campaigns; these will then be publishedin monographic form, hopefully by 2015. The campaignin 2011 lasted for five weeks and the workforce comprisedemployees from the Ephorate and the Danish Institute,together with local workmen and students from five Europeanuniversities.The theatre of Kalydon has been known as a monumentsince 1963, when constructions for the highway betweenNafpaktos and Agrinio exposed a series of steps on thesouth side of the hill of the sanctuary of Artemis Laphria,situated south of the city of Kalydon, some 350 m outsidethe city walls (Fig. 1). Some soundings were made by EuthymiosMastrokostas, the archaeologist then responsible for Aitolia, and it was decided that the road should beconstructed some 200 m further south. A brief report waspublished in which the theatre was described as a bouleuterion.A corner of seat-rows were left exposed and themonument was forgotten about until 2001, when the Danish–Greek excavations at Kalydon were re-initiated
Celebrating 25 years of archaeological research at the Danish Institute at Athens
The article gives a brief introduction to the Danish archaeological field projects in Kefallenia, Rhodes, Chalkis, Kalydon, Piraeus, Khania, Lechaion, Delphi and Sikyon as well as on Mount Pelion conducted through The Danish Institute at Athens

Building the Frontier: Frontier Fortifications in the Assyrian Empire
The purpose of this study is to give a general pictures of the different roles tat the act of building fortified settlements had in the creation and maintenance of frontier areas in Assyria. Different kinds of frontier were, it will be argued, affected by different policies on behalf of the Assyrian central administration, and different typologies of fortified settlements can be used to analyse different kinds of frontier policies

‘Finding Old Sikyon’, 2015: A preliminary report
The project “Ancient Sikyon” is a cooperation between the Ephorate of Antiquities of Corinth, the National Museum of Denmark, the Danish Institute at Athens and the Institute of Geoscience of the Christian-Albrechts University of Kiel. Conceived as a five-year project, its main aim is to identify the exact location, the major features and the urbanistic development of the city, prior to its relocation in 303 BC to a plateau nearby. This, however, is intended to serve the greater purpose of answering general questions of Archaic and Classical urbanism and the structure and organization of a famous centre of art and culture in comparison with other such centres like Corinth and Athens. The first year of research has already brought important information about the topography and material culture of Ancient Sikyon, which is presented in this preliminary report
Visual Understanding of Light Absorption and Waveguiding in Standing Nanowires with 3D Fluorescence Confocal Microscopy
Semiconductor nanowires are promising building blocks for next generation photonics. Indirect proofs of large absorption cross sections have been reported in nanostructures with subwavelength diameters, an effect that is even more prominent in vertically standing nanowires. In this work we provide a three-dimensional map of the light around vertical GaAs nanowires standing on a substrate by using fluorescence confocal microscopy, where the strong long-range disruption of the light path along the nanowire is illustrated. We find that the actual long-distance perturbation is much larger in size than calculated extinction cross sections. While the size of the perturbation remains similar, the intensity of the interaction changes dramatically over the visible spectrum. Numerical simulations allow us to distinguish the effects of scattering and absorption in the nanowire leading to these phenomena. This work provides a visual understanding of light absorption in semiconductor nanowire structures, which is of high interest for solar energy conversion applications
Nanowire-Aperture Probe: Local Enhanced Fluorescence Detection for the Investigation of Live Cells at the Nanoscale
Fluorescence microscopy has tackled many of the burning questions in cellular biology. Probing low-affinity cellular interactions remains one of the major challenges in the field to better understand cellular signaling. We introduce a novel approach the nanowire-aperture probe (NAP) to resolve biological signatures with a nanoscale resolution and a boost in light detection. The NAP takes advantage of the photonic properties of semiconductor nanowires and provides a highly localized excitation volume close to the nanowire surface. The probing region extends less than 20 nm into the solution, which can be exploited as a local light probe in fluorescence microscopy. This confined detection volume is especially advantageous in the study of cellular signaling at the cell membrane, as it wraps tightly around the nanowire. The nanowire acts as a local nanoaperture, both focusing the incoming excitation light and guiding photons emitted by the fluorophore. We demonstrate a 20-fold boost in signal-to-background sensitivity for single fluorophores and membrane-localized proteins in live cells. This work opens a completely new avenue for next-generation studies of live cells
