A framework of operator product expansion (OPE) allows us to study high-energy behaviour of Green functions. A calculation of such Green functions within chiral perturbation theory (PT) or resonance chiral theory (RT) and subsequent matching of the result to the OPE enables us to determine constraints for unknown parameters of the effective theories. We present such procedure for Green functions i

Female scientists play important leadership roles in the field and with the International Society for Stem Cell Research. We asked a number of these top researchers to share their personal stories and reflect on their career paths. Part II of this series will run in the October 2018 issue of Stem Cell Reports.

This study investigates patterns of seasonal variation in hours worked by women employed in home-based industrial production in Sweden in the early 20th century. Previous studies often describe workers in this type of production as the most flexible segment of industrial workers, and highly dependent on seasonal fluctuations in supply and demand. However, few have studied this empirically.

Känner du till Caloplaca monacensis och vet hur man skiljer den från dess närmaste släktingar? Om inte så har du chansen att lära känna arten lite bättre genom denna artikel.

This paper is based on a lecture held in Nagoya, Japan as part of a seminar on issues relating to disabled women, sexuality and sexual and reproductive health and rights (SRHR). I present preliminary results from the research project Sexual Citizenship and Disability: Implications for Theory, Practice and Policy, which focuses on sexual rights for people with mobility impairments. The data compris

Double U-pipe boreholes are the second most used type of ground heat exchangers after single U-pipe boreholes. The borehole thermal resistance is a key design and performance parameter for the double U-pipe boreholes. Another parameter that is particularly important for double U-pipe boreholes is the internal thermal resistance between the U-pipes. There is, however, a general lack of methods that

We have measured B/Ca in four core-top planktonic foraminiferal species (Globigerinoides ruber (white), Globigerinoides sacculifer (without final sac-like chamber), Neogloboquadrina dutertrei, and Pulleniatina obliquiloculata) from three depth transects (the Caribbean Sea, the southwestern Indian Ocean, and the Ontong Java Plateau) to evaluate the effect of dissolution on planktonic foraminiferal

Introduction The aim of this study was to describe the complications of ureteroscopy (URS) and to investigate whether performing URS outside normal working hours leads to increased risk for clinically significant complications. Material and methods A cohort of 486 consecutive patients treated with URS, with a total of 567 sessions between 2009 and 2015 at Helsingborg/Ängelholm Hospital, Sweden, wa

Background: Correct prediction of treatment response is a central goal of precision psychiatry. Here, we tested the predictive accuracy of a variety of pre-treatment patient characteristics, including clinical, demographic, molecular genetic, and neuroimaging markers, for treatment response in patients with social anxiety disorder (SAD). Methods: Forty-seven SAD patients (mean±SD age 33.9 ± 9.4 ye

We present a low-temperature processing scheme for the integration of either lateral or vertical nanowire (NW) transistors with a multilayer back-end-of-line interconnect stack. The nanowire device temperature budget has been addressed, and materials for the interconnect fabrication have been selected accordingly. A benzocyclobutene (BCB) polymer is used as an interlayer dielectric, with interconn

We have prepared electrodes for photo-electro-chemical cells which have enabled to pre-charge colloidal quantum dots in well-controlled fashion. Femtosecond transient absorption measurements were carried out revealing clear speed-up of the photo-induced charge carrier dynamics, particularly the recombination. Such studies allow to understand the behavior of light harvesting materials in operationa

Using resources shared within a social group – either in a cooperative or a competitive way - requires keeping track of own and others’ actions, which, in turn, requires well-developed short-term memory. Although short-term memory has been tested in social mammal species, little is known about this capacity in highly social birds, such as ravens. We compared ravens (Corvus corax) with humans in sp

Malafouris (2013) proposes that agency is an emergent product of the relational ontology of our material engagement. However, I suggest a distinction between meaning and agency for a better understanding of our relational ontology with things. Meaning is the payoff of the relational ontology, meaning emerges when an agent act within the world. Agency is the capability to act, signify, produce and

What can a music teacher do in a school where half of the students belong to minority cultures? In music education research there are many reports on the important role music has in preventing social exclusion. These reports refer to music’s power to serve both as aim and means to build efficient learning environments in multicultural schools (see for example Bamford, 2006; Bauer, 2005; Beck, 1993

The recent success in the development of high-precision printing techniques allows one to manufacture free-standing polymer structures of high quality. Two-photon polymerization lithography is a mask-less technique with down to 100 nm resolution that provides full geometric freedom. It has recently been applied to the nanofabrication of X-ray compound refractive lenses (CRLs). In this article we r
