The Neolithization of Northern Eurasia is marked by the emergence of pottery among hunter-gatherer societies. The driving forces behind the adoption of ceramic cooking vessels among non-agricultural societies remain unclear, although previous research, mainly in North East Asia (e.g. Japan, Korea and the Russian Far East), suggests that it was adopted as a specialist technology for processing aqua
During the Late Glacial, hunter-gatherers began using ceramic cooking containers in three separate geographic regions of East Asia: China, Japan and in the Russian Far East. While recent research has clarified the use of early pottery in Japan, very little is known about what led to the emergence of pottery in the other two areas, including the likely environmental, economic or cultural drivers.

Annual rates of adrenalectomy have doubled in the last 20 years as a consequence of increased detection of adrenal incidentalomas, improved biochemical diagnosis, genetic screening, and minimally invasive surgical techniques. Most adrenal incidentalomas are benign non-functional adrenocortical adenomas. Functional adrenal tumours are associated with high morbidity if left untreated, and this may b
Along with the rapid development of containerization technology, remarkable benefits have been created for developers and operation teams, and overall software infrastructure. Although lots of effort has been devoted to enhancing containerization security, containerized environments still have a huge attack surface. This paper proposes a secure cloud service for generating a Linux security module,
Arctic archaeologists generally accept that Dorset Paleo-Inuit (Tuniit) (c. 800 BC-1300 AD) toolkits exhibit high levels of typological uniformity across Arctic Canada and Greenland. This understanding implies that the artifacts were likely produced according to a standardized set of practices that were somehow ÷einforced over time and shared across the isolated sites and communities inhabiting th
Software startups use prototyping to develop and test business ideas and to validate market viability. While prototyping is emphasized in agile methods, there is little research on how startups can best utilise scarce resources to effectively use prototypes in their dynamic business context. We performed a case study of four startups and investigated how startups currently use prototyping to elici
Background: Prototyping is an established practice for user interface design and for requirements engineering within agile software development, even so there is a lack of theory on prototyping. Aims: The main research objective is to provide a means to categorise prototyping instances, in order to enable comparison and reflection of prototyping practices. Method: We have performed a systematic m
Large-scale software engineering is a collaborative effort where teams need to communicate to develop software products. Managers face the challenge of how to organise work to facilitate necessary communication between teams and individuals. This includes a range of decisions from distributing work over teams located in multiple buildings and sites, through work processes and tools for coordinatin
Nephelometers are regularly used for air quality monitoring through scattering measurements of aerosols in the atmosphere. Less attention has been paid to the potential of estimating soot morphological parameters from nephelometer measurements in combination with scattering theory. In this work, we perform a fundamental laboratory study where an Ecotech Aurora 3000 nephelometer is used for measuri
In a recent article we presented a model for hadronic rescattering, and some results were shown for pp collisions at LHC energies. In order to extend the studies to pA and AA collisions, the Angantyr model for heavy-ion collisions is taken as the starting point. Both these models are implemented within the general-purpose Monte Carlo event generator Pythia, which makes the matching reasonably stra
Objectives: To comprehend the relationship between various indicators of health service equity and patients’ health expenditure poverty in different regions of China, identify areas where equity in health service is lacking and provide ideas for improving patients’ health expenditure poverty. Method: Data from China Family Panel Studies (CFPS) in 2018 and the HFGT index formula were used to calcul
Background: We report the effects of the presentation of an idiopathic subdural hematoma (SDH) in an adult domestic pig on the glymphatic system, a brain-wide solute clearance system. This accidental finding is based on our recently published study that described this system for the first time in large mammals. Our current results define the need to investigate cerebrovascular pathologies that cou
Background: Semi-natural pastures are unfertilized grasslands with a long history of traditional low-input grazing management. This kind of pastures are recognized for their high species richness. However, as a consequence of modernization of agriculture, many of the semi-natural pastures have been lost during the last century, leading to a serious threat to farmland biodiversity. Semi-natural pas
In the past, development of the PYTHIA event generator has mainly concentrated on the physics of proton–proton collisions at high energies, as this is the most important case to modern high energy physics experiments. However, there are situations where more generic beam configurations are relevant. This thesis presents implementations and applications of such processes in PYTHIA. The two applicat
In rural China, marriage-squeezed men are more likely to experience discrimination than other males. Using data collected from Anhui Province in China on marriage-squeezed men’s quality of life, this study examines the influence of discrimination on the quality of life and the buffering effect of social support among this cohort. The results show that discrimination is a strong stressor, and its n

Breast implant-associated infections (BIAI) occur in approximately 2% of patients after augmentation mammoplasty. In some cases, BIAI can be treated conservatively, whereas others need implant removal. Knowledge of uncommon potential pathogens in BIAI is important to ensure optimal treatment of BIAI. In the present case report, we describe a case of bilateral late Campylobacter jejuni mastitis in
Numerical simulations have been conducted to investigate the effects of pin-fin arrangement and jet Reynolds number on heat transfer enhancement and flow characteristics of a concave confined jet impingement cooled surface conjugated with pin-fins. The results without a pin-fin are used as a baseline. Vortices and different sections of streamlines in the channel are employed to understand the flow
