Positive affect and parasympathetic activity : Evidence for a quadratic relationship between feeling safe and content and heart rate variability

There has been an increased interest in the study of underlying autonomic correlates of emotions. This study tests the hypothesis that high levels of high-frequency heart rate variability (HF HRV) are associated with positive emotions. In addition, we hypothesize that this association will differ according to the type of positive emotion. Also, based on recent findings, we tested the hypothesis th

Psychological and Physiological Effects of Compassionate Mind Training : a Pilot Randomised Controlled Study

The development of the compassionate self, associated with practices such as slow and deeper breathing, compassionate voice tones and facial expressions and compassionate focusing, is central to Compassion-Focused Therapy. This study explores the impact of a 2-week compassionate mind training (CMT) program on emotional, self-evaluative and psychopathology measures and on heart rate variability (HR

Microsurgical vasovasostomy: An option for men with post vasectomy psychological distress

Vasectomy is a practical and straightforward approach to birth control. This paper presented a 31-year-old patient who desired torestore his fertility five years after being vasectomized. He met several obstacles. He developed severe psychological distress withsymptoms of stress, anxiety, and aggression. He underwent microsurgical vasovasostomy, and vassal patency was confirmedby return of spermat

Samverkan som marknads­skapande – introduktionen av social impact bonds i Sverige och Finland

Det är vanligt att anta att marknad och samverkan befinner sig i motsatsställning: på en marknad ska det idealt sett råda konkurrens mellan olika aktörer medan samverkan vanligen handlar om flera aktörers gemensamma strävan mot samma mål. Stater och inte minst EU:s institutioner vidtar regelbundet åtgärder för att skapa marknader och konkurrens, och i dessa åtgärder finns ofta direkta försök att f

Stormtrupper i rymden : Starship Troopers från Heinlein till Verhoeven

Artikel om science fiction-författaren Robert Heinleins roman Starship Troopers från 1959 och Paul Verhoevens filmversion från 1997 med utgångspunkten att båda gestaltar ett fascistiskt samhälle. Skillnaden är att Heinlein ser det som något av ett ideal medan inslagen av ironi och absurditet i Verhoevens version bidrar till att det presenterade framtidsscenariot framstår som djupt problematiskt bo

Assessing transitions through socio-technical configuration analysis – a methodological framework and a case study in the water sector

Classic accounts of transitions research have predominantly built on reconstructions of historical transition processes and in-depth case studies to identify and conceptualize socio-technical change. While such approaches have substantively improved our understanding of transitions, they often suffer from methodological nationalism and a lack of generalizability beyond spatial and sectoral boundar

Aspirin as secondary prevention in colorectal cancer liver metastasis (ASAC trial) : study protocol for a multicentre randomized placebo-controlled trial

Background: Colorectal cancer is one the most common cancers in the western world with increasing incidence. Approximately 50% of the patients develop liver metastases. Resection of liver metastases is the treatment of choice although almost half of the resected patients get recurrence in the liver. Methods: The ASAC trial is a Scandinavian, multicentre, double-blinded, randomized, placebo-control

Comparative risk of suicide by specific substance use disorders : A national cohort study

Substance use disorders (SUDs) are important risk factors for suicide, yet little is known about how suicide risks vary by specific SUDs. We examined these risks for the first time in a large general population to facilitate comparisons across SUDs. A national cohort study was conducted of all 6,947,191 adults in Sweden. SUDs (opioid, sedative/hypnotic, hallucinogen, cannabis, amphetamine, cocaine

Reduced expression of OXPHOS and DNA damage genes is linked to protection from microvascular complications in long-term type 1 diabetes : the PROLONG study

Type 1 diabetes is a chronic autoimmune disease requiring insulin treatment for survival. Prolonged duration of type 1 diabetes is associated with increased risk of microvascular complications. Although chronic hyperglycemia and diabetes duration have been considered as the major risk factors for vascular complications, this is not universally seen among all patients. Persons with long-term type 1

Living labs and co-production : university campuses as platforms for sustainability science

Living labs and co-production are increasingly popular strategies for universities to address sustainability challenges and yet the links between them remain largely implicit. This paper discusses the potential of living labs to provide a holistic and iterative framework for the co-production of knowledge. The University Living Lab initiative was launched in 2012 to transform the University of Man

A Centralized and Scalable Uplink Power Control Algorithm in Low SINR Scenarios

Power control is becoming increasingly essential for the fifth-generation (5G) and beyond systems. An example use-case, among others, is the unmanned-aerial-vehicle (UAV) communications where the nearly line-of-sight (LoS) radio channels may result in very low signal-to-interference-plus-noise ratios (SINRs). The authors in (Chiang et al., 2007) proposed to efficiently and reliably solve this kind

Bounded Path-Loss Model for UAV-to-UAV Communications

In this paper, we focus on ultra-dense network modelingwhere both the Base Stations (BSs) and Mobile Terminals(MTs) are UAVs. In this case, two communication nodes canbe very close to each other. However, existing cellular networkanalyses typically use the standard unbounded path loss modelwhere received power decays like r^beta over a distance r. Thisstandard model is a good approximation for the

Characterizing the Small-Scale Fading for Low Altitude UAV Channels

In this contribution, a recently conducted measurement campaign in a suburban scenario for the Unmanned Aerial Vehicle (UAV) Air-to-Ground (A2G) radio channel is introduced.The downlink signals in an in-service Long Term Evolution (LTE) network were collected and utilized to extract the Channel Impulse Responses (CIRs). A high-resolution parameter estimation algorithm derived based on the Space-Al

A Complexity-Efficient High Resolution Propagation Parameter Estimation Algorithm for Ultra-Wideband Large-Scale Uniform Circular Array

Millimeter wave (mm-wave) communication with large-scale antenna array configuration is seen as the key enabler of the next generation communication systems. Accurate knowledge of the mm-wave propagation channels is fundamental and essential. In this contribution, a novel complexity-efficient high resolution parameter estimation (HRPE) algorithm is proposed for the mm-wave channel with large-scale

Non-invasive Characterization of Human AV-Nodal Conduction Delay and Refractory Period During Atrial Fibrillation

During atrial fibrillation (AF), the heart relies heavily on the atrio-ventricular (AV) node to regulate the heart rate. Thus, characterization of AV-nodal properties may provide valuable information for patient monitoring and prediction of rate control drug effects. In this work we present a network model consisting of the AV node, the bundle of His, and the Purkinje fibers, together with an asso
