Time-crystal ground state and production of gravitational waves from QCD phase transition

We propose a novel mechanism for the production of gravitational waves in the early Universe that originates from the relaxation processes induced by the QCD phase transition. While the energy density of the quark-gluon mean-field is monotonously decaying in real time, its pressure undergoes a series of violent oscillations at the characteristic QCD time scales that generate a primordial multi-pea

Att balansera på två hjul : en etnologisk undersökning av cykelkurser för vuxna inom projektet Frihet på cykel

Att kunna cykla ses som närmast självklart i Sverige. Den som inte kan avviker från normen och från föreställningen om vilka kunskaper och kompetenser en vuxen människa förväntas ha. Att inte kunna cykla blir också ett problem för individen som riskerar att begränsas och utestängas. Intresset för cykelkurser är därför stort. I denna rapport om Cykelfrämjandets projekt Frihet på cykel undersöks för

Monitoring moisture distribution in textile materials using grating interferometry and ptychographic X-ray imaging

Employing two recently developed X-ray imaging techniques, we investigated methods for observing moisture at different length scales in organic fibers and textiles. Using the coherent diffractive imaging technique of ptychographic tomography, structural features in a single coated wool fiber in both dry and humid conditions were observed at about 200 nm resolution. The reconstructed three-dimensio

Magnesium and potassium status in healthy subjects as assessed by analysis of magnesium and potassium in skeletal muscle biopsies and of magnesium in mononuclear cells

Magnesium and potassium concentrations were determined in plasma, erythrocytes and urine collected during 24 h, and in percutaneous muscle biopsies obtained in 30 healthy subjects. Magnesium was also analyzed in mononuclear cells. Men, compared to women, showed a higher urinary excretion of magnesium (p less than 0.05). The magnesium contents in mononuclear cells correlated significantly with the Magnesium and potassium concentrations were determined in plasma, erythrocytes and urine collected during 24 h, and in percutaneous muscle biopsies obtained in 30 healthy subjects.

Mirror QCD and cosmological constant

An analog of Quantum Chromo Dynamics (QCD) sector known as mirror QCD (mQCD) can affect the cosmological evolution due to a non-trivial contribution to the Cosmological Constant analogous to that induced by the ground state in non-perturbative QCD. In this work, we explore a plausible hypothesis for trace anomalies cancellation between the usual QCD and mQCD. Such an anomaly cancellation between t

Quantum Yang-Mills dark energy

In this short review, I discuss basic qualitative characteristics of quantum non-Abelian gauge dynamics in the non-stationary background of the expanding Universe in the framework of the standard Einstein-Yang-Mills formulation. A brief outlook of existing studies of cosmological Yang-Mills fields and their properties will be given. Quantum effects have a profound impact on the gauge field-driven

Proconvertase furin is down regulated in postural orthostatic tachycardia syndrome

Background: Postural Orthostatic Tachycardia Syndrome (POTS) is a cardiovascular autonomic disorder characterized by orthostatic intolerance and high prevalence among young women. The etiology of POTS is uncertain, though autoimmunity and inflammation may play an important role. We aimed to identify novel inflammatory biomarkers associated with POTS. Methods and Results: In the Syncope Study of Un

Between Sovietism and Americanization : Ideals of femininity during and after the Cold War in Finland

During the Cold War, along with the Americanization of its popular culture, Finland was also heavily exposed to Soviet ideological influences, including in relation to notions of desirable femininity. From the late 1960s onwards, Soviet influences can be seen in Finnish public discourses on fashion and decorative femininity. Soviet ideals are also reflected in the emphasis on gender neutrality and

‘We hid porn magazines in the nearby woods’ : Memory-Work and Pornography Consumption in Finland

This article presents the key findings of a Finnish memory-work project conducted in 2012 on consumer experiences and associations related to pornography. The memory-work material points to a high degree of reflexivity in definitions of pornographic preference as well as to drastic shifts in the ubiquity of pornography from the pre-1990s ‘age of scarcity’ to the current ‘age of plenty.’ At the sam
