Cultural adaptations and island ecology : Insights into changing patterns of pottery use in the Susuya, Okhotsk and Satsumon phases of the Kafukai sites, Rebun Island, Japan

Island chains provide access to terrestrial, coastal and offshore marine resources, attracting peoples and cultures and serving as conduits for migrations and long-distance exchange networks. Situated between Hokkaido and Sakhalin, Rebun Island connected the prehistoric cultures of northeast Asia in a major “marine highway”. Rebun was repeatedly settled by distinct cultures who originated in diffe

A Regal Authoritarian Turn in Cambodia

Cambodia’s transition from competitive to hegemonic authoritar-ianism, begun with a crackdown in 2017 which saw the opposition Cambodia National Rescue Party dissolved, and institutionalised in non-competitive parliamentary elections in 2018 in which long- incumbent Cambodian People’s Party won all seats, has been teem-ing with references to the monarchy. Whilst Prime Minister Hun Sen has long bui

Volatile organic compound emission in tundra shrubs : Dependence on species characteristics and the near-surface environment

Temperature is one of the key abiotic factors during the life of plants, especially in the Arctic region which is currently experiencing rapid climate change. We evaluated plant traits and environmental variables determining leaf temperature in tundra shrubs and volatile organic compound (VOC) emissions with field measurements on deciduous tundra shrubs, Salix myrsinites and Betula nana, and everg

The impact of ethnicity on glucose homeostasis after gestational diabetes mellitus

Background and aims: Ethnicity influences the prevalence of gestational diabetes (GDM) and its progression to manifest diabetes postpartum, being higher in non-European populations. This may partly be explained by differences in insulin secretion and action. Aims of the present study were to evaluate glucose homeostasis after GDM, the impact of ethnicity and other determinants of glucose toleranceBackground and aims: Ethnicity influences the prevalence of gestationaldiabetes (GDM) and its progression to manifest diabetes postpartum, beinghigher in non-European populations.

Retinal indoleamine accumulating neurons

A previously unknown set of neurons, characterized by their ability to accumulate indoleamines, has been identified in the retina of Cebus monkeys, rabbits, cats, pigeons, chicken, goldfish and lampreys. They are not demonstrable with presently available techniques in humans, Cynomolgus monkeys, cows, pigs and rats. The neurons are called indoleamine accumulating neuron and form a subset of amacri

Morphological variability of peteinoid acritarchs from the Middle Ordovician of Öland, Sweden, and implications for acritarch classification

Investigation of large populations of peteinoid acritarchs recovered from Middle Ordovician strata of the Hälludden and Horns Udde quarry sections (Öland, Sweden) allows for statistical analyses based on morphometric measurements. The results indicate the presence of assemblages with a continuous variability of morphotypes, thus a distinction of different peteinoid acritarch taxa in the sections p

Strategic Alterations of Posture are Delayed in Parkinson's Disease Patients during Deep Brain Stimulation

Parkinson's disease (PD) is characterized by rigidity, akinesia, postural instability and tremor. Deep brain stimulation (DBS) of the subthalamic nucleus (STN) reduces tremor but the effects on postural instability are inconsistent. Another component of postural control is the postural strategy, traditionally referred to as the ankle or hip strategy, which is determined by the coupling between the

Antiretroviral Therapy and Retention in Care Experiences and Needs of Adolescents Living with HIV in Southern Ethiopia

Background: Adolescents with HIV are faced with challenges when taking care of their medication, which affects their treatment adherence. Therefore, this study aimed to explore the experiences and needs of adolescents living with HIV regarding their antiretroviral therapy adherence and retention in care in southern Ethiopia.Methods: An inductive qualitative study design was applied to explore adol

Sanning och konsekvens för svenska vattenledningar

Detta arbete kick-startar AI (artificiell intelligens) för ledningsunderhåll i VA-branschen i Sverige. Arbetet med befintliga VA-nät är idag främst reaktivt; man reparerar läckor vartefter man blir varse dem, ibland till stora kostnader om läckan är omfattande och akut. Med denna artikel vill vi sätta fokus på proaktivt arbete med ledningsnät och diskutera riskanalys inom området. En ANN-modell soThis work kick-starts AI (artificial intelligence) for pipe management among Swedish water utilities. The current work with pipe management is mainly reactive; leaks are repaired after they are detected, sometimes with large costs if the leakage is extensive and critical. With this article, we want to focus on proactive pipe network management and discuss risk analysis in the field. A previously d

Ecology and evolution of large-scale bird migration patterns : A natural history and comparative study of the migration in common and little ringed plovers

Migration distance and seasonal redistribution patterns may vary between and within bird populations. A common pattern is leap-frog migration, in which northerly breeding populations migrate farther and winter south of more southerly breeding populations. Another common pattern is difference in migration distances between males and females within the same population. Evidently different population

Capitalizing on transparency: commercial surveillance and pharmaceutical marketing after the Physician Sunshine Act

How corporations surveil and influence consumers using big data tools is a major area of research and public debate. However, few studies explore it in relation to physicians in the USA, even though they have been surveilled and targeted by the pharmaceutical industry since at least the 1950s. Indeed, in 2010, concerns about the pharmaceutical industry’s undue influence led to the passing of the P

The 2019-2020 EURADOS WG10 and RENEB Field Test of Retrospective Dosimetry Methods in a Small-Scale Incident Involving Ionizing Radiation

With the use of ionizing radiation comes the risk of accidents and malevolent misuse. When unplanned exposures occur, there are several methods which can be used to retrospectively reconstruct individual radiation exposures; biological methods include analysis of aberrations and damage of chromosomes and DNA, while physical methods rely on luminescence (TL/OSL) or EPR signals. To ensure the qualit

End-to-End Estimation of Hand- and Wrist Forces From Raw Intramuscular EMG Signals Using LSTM Networks

Processing myoelectrical activity in the forearm has for long been considered a promising framework to allow transradial amputees to control motorized prostheses. In spite of expectations, contemporary muscle-computer interfaces built for this purpose typically fail to satisfy one or more important desiderata, such as accuracy, robustness, and/or naturalness of control, in part due to difficulties

Humanister i offentligheten : Kunskapens aktörer och arenor under efterkrigstiden

Det finns en tydlig berättelse om hur humaniora marginaliserades i efterkrigstidens Sverige: i ingenjörernas, teknokraternas och samhällsvetarnas land fanns det inget utrymme för bildning, filosofi och historia. Denna bok utmanar en sådan föreställning och visar hur påtagligt närvarande humaniora var i tidens offentlighet. Genom att anlägga ett kunskapshistoriskt perspektiv åskådliggör författarna
