Visualization and Analysis Techniques for Three Dimensional Information Acquired by Confocal Microscopy
Confocal Scanning Laser Microscopy (CSLM) is particularly well suited for the acquisition of 3-dimensional data of microscopic objects. In the CSLM a specific volume in the object is sampled during the imaging process and the result is stored in a digital computer as a three-dimensional memory array. Optimal use of these data requires both the development of effective visual representations as well as analysis methods. In addition to the well known stereoscopic representation method a number of alternatives for various purposes are presented. When rendering in terms of solid-looking or semitransparent objects is required, an algorithm based on a simulated process of excitation and fluorescence is very suitable. Graphic techniques can be used to examine the 3-dimensional shape of surfaces. For (near-)real time applications a representation method should not require extensive previous data-processing or analysis.
From the very extensive field of 3-D image analysis two examples are given

Automated team selection and compliance checking in business processes
Plenty of activities in many business contexts must be performed
collaboratively, e.g., in a hospital or when organising
a conference. Tasks such as team composition and allocation
are usually performed manually and on the ground of
limited criteria such as individual skills, a.o. because adequate
automatic support is missing. This paper addresses
this shortcoming. We present an approach for team selection
and compliance checking in business processes, which
includes (i) a language for describing teams; (ii) a way to de-
ne team selection conditions and policies related to team
composition; and (iii) a mechanism for the automatic resolution
of the team selection conditions and for team-related
compliance checking based on formal ontologies.Austrian Research Funding Association (FFG) 845638 (SHAPE)Ministerio de Ciencia e Innovación TIN2009-07366 (SETI)Ministerio de Economía y Competitividad TIN2012-32273 (TAPAS)Junta de Andalucía TIC-5906 (THEOS
Модернизация автоматической системы регулирования уровня воды в парогенераторе типа ПГВ-440 Нововоронежской АЭС
The Innoslab design, already established for neodymium doped laser crystals, was applied to ytterbium doped laser materials. Recent progresses in brightness of high power diode lasers facilitate efficient pumping of quasi-three-level laser materials. Innoslab amplifiers are compared to competing thin-disk and fiber fs-amplifiers. A compact diode-pumped Yb:YAG Innoslab fs-oscillator-amplifier system, scalable to the kilowatt range, was realized. Numerical simulations result in conditions for high efficiency and beam quality. Nearly transform and diffraction limited 680 fs pulses at 400 W average output power and 76 MHz repetition rate without using CPA technology have been achieved at room temperature so far
Insights from practice: A handbook for supervisors of modern doctorate candidates
Doctoral degrees are no longer simply a training ground for the next generation of academics. Different forms have evolved to encompass multi-and trans-disciplinary study by practitioners within their work context (Lester, 2004). The designation has also changed to include terms such as professional, industrial or practice-based PhDs or Doctorates (Fillery-Travis, 2012). For the rest of this handbook we will identify these doctorate types as the modern doctorates. These developments in doctoral education are driven by the contribution to knowledge exchange that these degrees can make and how they are perceived as facilitating innovation and growth within diverse sectors.
But supervision of modern doctorates is not fully codified although it requires a number of capabilities (academic and professional) that are recognised as being beyond those needed for conventional PhD supervision such as advising and facilitation (Boud & Costley, 2007)
Expression of an Arc-Immunoreactive Protein in the Adult Zebrafish Brain Increases in Response to a Novel Environment
Zebrafish are a powerful research tool in the field of neuroscience, offering several logistical and physiological advantages over rodents as a research model. However, the molecular dynamics of this model organism, especially with regards to learning and memory, are scarcely known. The current study explored the zebrafish brain for the presence of a protein bearing a similar function to the activity-regulated, cytoskeleton-associated protein (Arc), a critical player in synaptic plasticity. The adult zebrafish brain was found to express a protein with immunoreactivity against the anti-Arc antibody H-300. Immunoreactivity was detected ubiquitously, especially in areas known as adult progenitor cell zones. The protein, termed Arc-immunoreactive protein (AIP), increased in the telencephalon but not the optic tectum 60 min after exposure to a novel environment. Epileptiform brain activity, however, did not induce AIP expression. Evidence presented herein suggests AIP may be the neuropeptide Y receptor rather than a zebrafish homolog of Arc
Bilayer manganites: polarons in the midst of a metallic breakdown
The exact nature of the low temperature electronic phase of the manganite
materials family, and hence the origin of their colossal magnetoresistant (CMR)
effect, is still under heavy debate. By combining new photoemission and
tunneling data, we show that in La{2-2x}Sr{1+2x}Mn2O7 the polaronic degrees of
freedom win out across the CMR region of the phase diagram. This means that the
generic ground state is that of a system in which strong electron-lattice
interactions result in vanishing coherent quasi-particle spectral weight at the
Fermi level for all locations in k-space. The incoherence of the charge
carriers offers a unifying explanation for the anomalous charge-carrier
dynamics seen in transport, optics and electron spectroscopic data. The
stacking number N is the key factor for true metallic behavior, as an
intergrowth-driven breakdown of the polaronic domination to give a metal
possessing a traditional Fermi surface is seen in the bilayer system.Comment: 7 pages, 2 figures, includes supplementary informatio
