Ancient schwannomas rarely found in the central nervous system and ancient change in an intracranial schwannoma (intracranial portion of the trigeminal nerve) is extremely rare. A seventy-year man presented with headache of 3 months duration and one episode of generalized tonic-clonic seizures. Imaging findings were suggestive of left temporal high grade lesion. During surgery there was well...
The past decade has witnessed a revolution in ancient DNA (aDNA) research. Although the field's focus was previously limited to mitochondrial DNA and a few nuclear markers, whole genome sequences from the deep past can now be retrieved. This breakthrough is tightly connected to the massive sequence throughput of next generation sequencing platforms and the ability to target short and degraded D...
Is inequality largely the result of the Industrial Revolution? Or, were preindustrial incomes as unequal as they are today? For want of sufficient data, these questions have not yet been answered. This paper infers inequality for 29 ancient, pre-industrial societies using what are known as social tables, stretching from the Roman Empire 14 AD, to Byzantium in 1000, to England in 1688, to Nueva ...
Aimed at ancient architectures which own the characteristics of huge data quantity, fine-grained and high-precise, a 3D fine management and visualization method for ancient architectures based on the integration of 2D and 3D GIS is proposed. Firstly, after analysing various data types and characters of digital ancient architectures, main problems and key technologies existing in the 2D and 3D d...
Were the ancients Greeks “racists” in the modern sense of the term “racist”? The terms ancient Greek “proto-racism”, tribalism (and/or racism) are used here to denote the abstract, narcissistic notion that not only the non-Greek barbarians, but also certain ancient Greek tribes (like the Macedonians, the Boeoteans etc.) should be excluded from the Hellenic community, for they were considered to...
Genetic material sequenced from ancient samples is revolutionizing our understanding of the recent evolutionary past. However, ancient DNA is often degraded, resulting in low coverage, error-prone sequencing. Several solutions exist to this problem, ranging from simple approach, such as selecting a read at random for each site, to more complicated approaches involving genotype likelihoods. In t...
We present a number of experiments on parsing the Ancient Greek Dependency Treebank (AGDT), i.e. the largest syntactically annotated corpus of Ancient Greek currently available (350k words ca). Although the AGDT is rather unbalanced and far from being representative of all genres and periods of Ancient Greek, no attempt has been made so far to perform automatic dependency parsing of Ancient Gre...
In medical history of different nations, there are numerous documents concerning cancer. The present study is an investigation in ancient books to determine the part that medicine of Iran has played in the recognition of cancer. In all 31 Iranian medical and 5 Islamic medicine books mostly from 8 to 18 cent. A.D. have been examined. The findings showed that cancer in ancient medical books of Ir...
The identity and history of the indigenous groups who occupied the Lesser Antilles during the ceramic periods remain highly controversial. Although recent archaeological evidence has challenged hypotheses concerning the organization of human groups in this region, more biological data are needed to fully inform the discussion. Our study provides, to our knowledge, the first palaeogenetic data f...
