Genetic polymorphisms are powerful model systems to study the maintenance of diversity in nature. In some systems, polymorphisms are limited to female coloration; these are thought to have arisen as a consequence of reducing male mating harassment, commonly resulting in negative frequency-dependent selection on female color morphs. One example is the damselfly Ischnura elegans, which shows three f
Intraductal papillary mucinous neoplasm (IPMN) is one of the most common cystic neoplasms of the pancreas. It is a heterogeneous disease and can be divided into ductal types and morphological subtypes. The incidence of IPMN is increasing, likely due to the widespread use of cross-sectional imaging and a growing elderly population. IPMN poses an increasing demand on the health care system. Current
Machine learning is ubiquitous in today’s society, with promising applicationsin the field of natural language processing (NLP), so that computers can handlehuman language better, and within the medical community, with the promiseof better treatments. Machine learning can be seen as a subfield of artificialintelligence (AI), where AI is used to describe a machine that mimics cognitivefunctions tha
Atherosclerosis is the underlying cause for myocardal infarction, stroke and peripheral arterial disease, collectively referred to as cardiovascular diseases. These represent the major cause of death globally. Phenotypic modulationof vascular smooth muscle cells form a contractile to a synthetic state and subsequent migration into the intima, isone of the prime events that marks the genesis of ath
Introduction: Severe obstetric complications increase with the number of previous cesarean deliveries. In the Nordic countries most women have two children. We present the risk of severe obstetric complications at the delivery following a first elective or emergency cesarean and the risk by intended mode of second delivery. Material and methods: A two-year population-based data collection of sever
Formal subdivision of the Cambrian System into four series and ten stages is in progress. The base of Cambrian Stage 3 (provisional), which is conterminous with the base of Cambrian Series 2 (provisional), is expected to be placed at a horizon close to the first appearance of trilobites, which marks the onset of the largest phase of the Cambrian explosion. Conceptually, an ideal boundary position
Among all the different ways used by the social State to promote higher labour standards the public procurements have always played an important role. Exploiting them economic attractiveness, in fact, most Countries used to insert in them several types of social clauses, so to oblige the awarded tenderer to grant a broad series of rights to the employees involved in the execution of the procuremen
In a solid-state host, attractive electron-electron interactions can lead to the formation of local electron pairs which play an important role in the understanding of prominent phenomena such as high T c superconductivity and the pseudogap phase. Recently, evidence of a paired ground state without superconductivity was demonstrated at the level of single electrons in quantum dots at the interface
his paper investigates regional business cycle co-movements in Austria–Hungary from 1867 to 1913. Economic theory suggests that rising market integration induces sectoral specialisation, resulting in a reduction in the correlation of regional GDP cycles (Krugman effect). However, the synchronisation of business cycles is expected to increase because of the growing inter-linkages among regions led
