Evolutionary and Ecological Processes Underlying Geographic Variation in Innate Bird Songs
Ecological and evolutionary processes underlying spatial variation in signals involved in mate recognition and reproductive isolation are crucial to understanding the causes of population divergence and speciation. Here, to test hypotheses concerning the causes of song divergence, we examine how songs of two sister species of Atlantic Forest suboscine birds with innate songs, the Pyriglena fire-ey
Localizing Unsynchronized Sensors With Unknown Sources
We propose a method for sensor array self-localization using a set of sources at unknown locations. The sources produce signals whose times of arrival are registered at the sensors. We look at the general case where neither the emission times of the sources nor the reference time frames of the receivers are known. Unlike previous work, our method directly recovers the array geometry, instead of fi

Peritoneal dialysis (PD) uses the peritoneal membrane for dialysis. The peritoneal membrane is a thin layer of tissue that lines the abdomen. The lining is used as a filter to help remove extra fluid and poisonous waste from the blood. Everybody is unique. What is normal for one person’s membrane may be very different from another person’s. The kidney care team wants to provide each person with th

A practical and environmentally friendly protocol for synthesis of α-deuterated carboxylic acids
α-deuterated carboxylic acids have been synthesized from the corresponding malonic acids via hydrogen/deuterium exchange and decarboxylation in presence of D2O. The method is general, mild and efficient and does not require organic solvents or other additives. Yields range between 83% and 94% and purification was not necessary. Starting materials were easy accessible and the α-deuterated carboxyli
Modeling cancer’s ecological and evolutionary dynamics
In this didactic paper, we present a theoretical modeling framework, called the G-function, that integrates both the ecology and evolution of cancer to understand oncogenesis. The G-function has been used in evolutionary ecology, but has not been widely applied to problems in cancer. Here, we build the G-function framework from fundamental Darwinian principles and discuss how cancer can be seen th

Quality of life, sense of coherence and occupational balance one year after an occupational therapy intervention for people with depression and anxiety disorders
BACKGROUND: Quality of life (QOL), sense of coherence (SOC) and occupational balance (OB) have been found to increase after rehabilitation among people living with depression and anxiety. However, these aspects have not been investigated over time in participants with different paid work situations, such as being on sick leave or not. OBJECTIVE: To describe and compare the self-rated QOL, SOC and
Enforcing Corporate Opportunity Rules : Antitrust Risks and Antitrust Failures
This paper identifies the potential competitive harm in the enforcement of corporate opportunity rules and shows that antitrust intervention cannot sufficiently address such harm. It suggests that the current antitrust framework is ill-suited to tackle the anticompetitive risks, in particular, regarding effects on innovation. The paper first explains corporate opportunity rules in EU member States
APOE -ε4 modulates the association between regional amyloid deposition and cognitive performance in cognitively unimpaired middle-aged individuals
Purpose: To determine whether the APOE-ε4 allele modulates the relationship between regional β-amyloid (Aβ) accumulation and cognitive change in middle-aged cognitively unimpaired (CU) participants. Methods: The 352 CU participants (mean aged 61.1 [4.7] years) included completed two cognitive assessments (average interval 3.34 years), underwent [18F]flutemetamol Aβ positron emission tomography (PE
Fluorescence excitation enhancement by waveguiding nanowires
The optical properties of vertical semiconductor nanowires can allow an enhancement of fluorescence from surface-bound fluorophores, a feature proven useful in biosensing. One of the contributing factors to the fluorescence enhancement is thought to be the local increase of the incident excitation light intensity in the vicinity of the nanowire surface, where fluorophores are located. However, thi
Did the Bronze Age deforestation of Europe affect its climate? A regional climate model study using pollen-based land cover reconstructions
This paper studies the impact of land use and land cover change (LULCC) on the climate around 2500 years ago (2.5 ka), a period of rapid transitions across the European landscape. One global climate model was used to force two regional climate models (RCMs). The RCMs used two land cover descriptions. The first was from a dynamical vegetation model representing potential land cover, and the second
Preterm or early term birth and long-term risk of asthma into midadulthood : A national cohort and cosibling study
Background Preterm birth is associated with pulmonary complications early in life; however, long-term risks of asthma into adulthood are unclear. Objective To determine asthma risks from childhood into adulthood associated with gestational age at birth in a large population-based cohort. Methods A national cohort study was conducted of all 4 079 878 singletons born in Sweden during 1973-2013, foll
THE LGBT MOVEMENT IN VIETNAM1
This chapter examines mobilisation around sexuality and gender identity in Southeast Asia through an examination of how the lesbian, gay, bisexual, and transgender (LGBT) movement in Vietnam has pursued full recognition and equal rights for all, regardless of sexuality and gender. As the chapter details, the Vietnamese LGBT movement is composed of informal activist groups and networks as well as f
Stimulating fertility awareness : The importance of getting the language right
While education about fertility is not intrinsically controversial, finding the right language to communicate the topic can be challenging, as there are several risks of unintended negative effects such as dissonance, anxiety, culpability, and stigma due to social norming. In this article, we share some of our learnings from promoting fertility awareness in the hope that they will inspire further
Neisseria gonorrhoeae co-opts C4b-binding protein to enhance complement-independent survival from neutrophils
Neisseria gonorrhoeae (Gc) is a human-specific pathogen that causes the sexually transmitted infection gonorrhea. Gc survives in neutrophil-rich gonorrheal secretions, and recovered bacteria predominantly express phase-variable, surface-expressed opacity-associated (Opa) proteins (Opa+). However, expression of Opa proteins like OpaD decreases Gc survival when exposed to human neutrophils ex vivo.

Electronical digital instrument (EDI) - Digital music making with children, youth and music teacher students
Making music with digital tools might be considered common knowledge in music education. However, there are vast numbers of music teachers who feel insecure when it comes to actually using it as a prominent tool for music making in their classrooms. The objective of this workshop is to show how students of different ages together with their music teachers create, produce and perform music by EDI.
The Digital Student - challenges and opportunities using the computer as main instrument in music education in Sweden
Teachers in the aesthetic program in upper secondary school in Sweden have identified that there are great opportunities and challenges in teaching and working with students who have EDI as their main instrument. From a student perspective it has relevance to being part of meaningful music education developing their musical identity. Students playing EDI can explore an array of electronical musica
