Background Increased vitamin B6 catabolism related to inflammation, as measured by the PAr index (the ratio of 4-pyridoxic acid over the sum of pyridoxal and pyridoxal-5'-phosphate), has been positively associated with lung cancer risk in two prospective European studies. However, the extent to which this association translates to more diverse populations is not known. Materials and methods For th
This thematic issue is devoted to how human service work may be influenced by accentuated administrative processes, as well as reinforced by digitalization, in contemporary society. The public sector has expanded the requirements of documentation, auditing and evaluation practices. Policy, problems and persons are shaped and enacted in meetings and documents. Meetings and documents comprise the fo
To write about clients is an established routine in countless institutional settings, regardless of the fact that clients themselves seldom feel that the produced texts mirror or summarize their experiences. But what, more specifically, is left unwritten when staff starts typing on the keyboard to insert a piece of daily life into the computer? This article draws on data on violent events in Swedi
Resolution of interference between competing memories is often critical for remembering. This study employed multivariate pattern analysis (MVPA) of electroencephalographic (EEG) data to investigate the temporal dynamics of retrieval competition and competition resolution. Competition between memories was created through the AB/AC interference paradigm.

Attosecond pulses allow for imaging of very fast processes, like electron dynamics. Stockman et al. suggested to use these pulses in connection with a Photoemission electron microscope (PEEM) to study the ultrafast dynamics of plasmons (Stockman et al. Nat Photonics 1:539–544, 2007). For efficient plasmon studies, the repetition rate of the attosecond pulses used needs to be higher than a few kHz
Dynamic quantum effects in biological systems is a hotly debated question, which since recently has been experiencing renewed wave of broad attention [1]. This discussion was initiated by the application of the multidimensional spectroscopy techniques for investigating dynamics in biological complexes. Is nature really optimized to use non-trivial quantum effects, like dynamically evolving coheren
Spectral oscillations in 2D molecular spectroscopy of the displaced oscillator system and their phase relationships are analyzed. The phase maps of the dispersive and absolute-valued signals give hints for experimental probing of peak oscillations.
A variety of two-dimensional electronic spectroscopy experiments on natural lightharvesting complexes reveal inter-chromophore coupling and monitor ultrafast dynamics, furthering understanding of the way these proteins function and the underlying design principles of photosynthesis.
Two-dimensional Fourier transform electronic spectra were recorded for the LH3 light harvesting complex. The spectra reveal the weak coupling between B800 molecules, the ultrafast dynamics within B820 and energy flow from B800 to B850.
Two-dimensional optical spectroscopy is a potent tool for studying correlations among different vibrational and electronic transitions as well as other nonlinear properties of molecules and materials. This chapter utilizes recently developed phase-stabilized two-dimensional electronic Fourier-transform spectroscopy to probe electronic couplings among different chromophores and explore the distribu
This thesis consists of three papers that study individual preferences. The focus of the first two papers is on time preferences. In the third paper, preferences regarding how inequality in health and income should be defined are elicited.In the first paper, we study the long-term stability of survey-based subjective time preferences using a Dutch household survey panel. We find that while the ind
The two-photon absorption (TPA) properties of β-carotene (beta-carotene) in chloroform solution were investigated over the 590-790 nm wavelength range. The TPA was characterized using the open-aperture z-scan technique with picosecond pulses provided by a widely traveling-wave optical parametric amplifier (OPA) pumped with a Ti:sapphire laser amplifier. We found the 0.2-1 cm/GW values of two photo
Attempts to measure the capitalization of local taxes into property prices, starting with Oates (1969), have suffered from a lack of local public service controls. We revisit this vast literature with a novel dataset of 947 time-varying local characteristic and public service controls for all municipalities in Sweden over the 2010-2016 period. To make use of the high dimensional vector of control
Digital work has become part of social workers’ daily routines in countries where digitalisation is on the agenda. As a consequence, documentation practices are expanding—on paper as well as digitally—and include reporting detailed statistics about client interventions, filling in digital forms, and fulfilling local and national performance measurement goals. Standardised formulas with tick-box an
Femtosecond spectroscopy is an important tool used for tracking rapid photoinduced processes in a variety of materials. To spatially map the processes in a sample would substantially expand the method’s capabilities. This is, however, difficult to achieve, due to the necessity of using low-noise detection and maintaining feasible data acquisition time. Here, we demonstrate realization of an imagin
