Estimating the age–metallicity distribution of a stellar sample from the probability distributions of the individual stars

Estimating age distributions, or star formation histories, of stellar populations in the Milky Way is important in order to study the evolution of trends in elemental abundances and kinematics. We build on previous work to develop an algorithm for estimating the age-metallicity distribution which uses the full age-metallicity probability density functions (PDFs) of individual stars. No assumptions

Homeostatic swimming of zooplankton upon crowding : The case of the copepod Centropages typicus

Crowding has a major impact on the dynamics of many material and biological systems, inducing effects as diverse as glassy dynamics and swarming. While this issue has been deeply investigated for a variety of living organisms, more research remains to be done on the effect of crowding on the behaviour of copepods, the most abundant metazoans on Earth. To this aim, we experimentally investigate the

Impact of Specific Bowel Symptoms on Quality of Life in Patients with Midgut Neuroendocrine Tumours

Introduction: Patients with midgut neuroendocrine tumours (NETs) suffer from decreased health-related quality of life (HRQoL), in large part due to bowel symptoms. However, it is unknown which bowel symptoms affect HRQoL the most. An enhanced understanding of this is essential to better focus treatment on this aspect of the disease. This study aimed to determine which bowel symptoms affect HRQoL t

Climate change and energy policy efforts in Chile: Up in smoke?

Abstract in UndeterminedThe purpose of this study is to preliminarily evaluate Chile’s energy and climate policy performance historically (1971-2007). The objective is to estimate different indicators in relation to energy and CO2 emission intensities, and identify policy instruments in the light of estimated trends and related structural issues. The methodology is based on a top-down decompositio

Gestational Islet Autoimmunity, Infections, and Type 1 Diabetes

The intention of this thesis was to investigate autoimmune markers for type 1 diabetes, together with signs of enterovirus infections during the pre- and perinatal period of life, and their possible association with the development of diabetes during childhood, adolescence, and young adulthood. We found that: 1. Newborns with ABO immunization, linked in epidemiological studies with heightened diab

Symptom Relief and Palliative Care during the Last Week of Life among Patients with Heart Failure : A National Register Study

Background: Heart failure is a disease with high morbidity, mortality, and physical and psychological burden. More knowledge about the care provided for patients with heart failure close to death is needed. Objective: The aim was to describe key aspects of palliative care during the last week of life in patients with heart failure, as reported by healthcare professionals. Design: This is a nationa

Characteristics of two-color holographic recording in lithium niobate doped with thulium

We report ultraviolet-induced transient and stable absorption and two-color holographic recording at 514, 633, and 830 nm in thulium doped stoichiometric LiNbO 3 crystal. The gating light at 355 nm increased the diffraction efficiency and sensitivity. We found the optimum gating-recording intensity ratio for maximum diffraction efficiency and weak nonvolatile holographic storage with gating.

Using Cards to Facilitate Conversations About Wishes and Priorities of Patients in Palliative Care

To avoid discomfort, health care professionals may hesitate to pursue conversations about end of life with patients. Certain tools have the potential to facilitate smoother conversations in this matter. The objective was to explore the experiences of patients in palliative care in using statement cards to talk about their wishes and priorities. Forty-six cards with statements of wishes and priorit

Brain injury after cardiac arrest

As more people are surviving cardiac arrest, focus needs to shift towards improving neurological outcomes and quality of life in survivors. Brain injury after resuscitation, a common sequela following cardiac arrest, ranges in severity from mild impairment to devastating brain injury and brainstem death. Effective strategies to minimise brain injury after resuscitation include early intervention w

Prevalence, severity and impacts of breathlessness in Indian adults : An exploratory, nationally representative, cross-sectional online survey

There are no known estimates of the prevalence, severity and impacts from breathlessness in low- and middle-income countries. This study aimed to explore the prevalence, severity, self-attributed underlying conditions and impacts of breathlessness limiting exertion in community-dwelling adults in India. This exploratory, population-based online survey recruited a pre-planned sample of 3,000 adult

CONCEPTUALIZING THE IMPACT OF DIGITAL BUSINESS MODELS ON PRIVACY CONCERNS

Digital technologies have enabled novel forms and reconfigurations of value creation, delivery, and capture. These new reconfigurations challenge the conventional notion of value creation with digital business models. On that premise, the widening of privacy concerns, alert us that organizations of the elite digital, like Netflix, Amazon, and Spotify, design technology to feed on personal data, ba

Social Media and Development: Understanding NGO practices and perceptions

The goal of this study is to identify the perspectives that development NGOs attribute to organisational social media, and furthermore elaborate on an appropriate categorisation of these perspectives for social media use by development NGOs. How social media is used in the area of development, where the use goes far beyond the private sector purpose of publicity and converting a sale, is a key iss

Enabling and impeding factors for organizational adaptive capacity – a review of the literature

Organizations responsible for maintaining critical societal functions must be able to handle both events that can be foreseen and events that come more or less as surprises. Therefore, proactive risk management strategies that build on capacity to adapt to new and unforeseen circumstances must complement strategies that build on the ability to plan for events that can be anticipated on beforehand.

Low-Dose Morphine Does Not Cause Sleepiness in Chronic Obstructive Pulmonary Disease : A Secondary Analysis of a Randomized Clinical Trial

Rationale: Regular, low-dose, sustained-release morphine is frequently prescribed for persistent breathlessness in chronic obstructive pulmonary disease (COPD). However, effects on daytime sleepiness, perceived sleep quality, and daytime function have not been rigorously investigated. Objectives: We sought to determine the effects of regular, low-dose, sustained-release morphine on sleep parameter

Identification and Prioritization of Factors for an Adequate Housing Environment : Involvement of Community-Dwelling Older Adults in the Early Stage of a Housing Development Process

Ageing societies are facing major housing challenges. Understanding and addressing older adults' diverse housing needs and preferences are crucial. Having access to suitable and sustainable housing options can improve social cohesion, independence, health, and well-being. Participatory processes in housing development can enhance inclusion and democratic participation. This study uses Ramlösa Port

Heart rate response and recovery in cycle exercise testing : normal values and association with mortality

Aims. Chronotropic incompetence and impaired heart rate (HR) recovery are related to mortality. Guidelines lack specific reference values for HR recovery. We defined normal values and studied blunted HR response and recovery and mortality risk. Methods and results. We included 9917 subjects (45% females) aged 18–85 years who performed a cycle exercise test. We defined normal values for peak HR, HR
