Flint Tools and their makers
Authors: Humphreys Humphrey 
Published: August 2016

[It should be observed that the Milankovich Chronology, the alternation of core and flake cultures, and the association of flake-tools with Neanderthaloid types and of bifaces with Homo Supiens are all very much in question at the present time. But subject to this qualification, the figures here printed may give some sort of approximation to the length of the periods covered. EDITOR].Our knowledge of man's ancestry and of the early phases of his own existence can only be increased by new discoveries of flint tools and fossil man in association. Such finds have been very rare because industrial excavations like gravel pits, which might yield the evidence if carefully watched by skilled observers, do in fact destroy it. The unearthing of the Swanscombe skull in 1935 shows what might happen if the ability to recognise flint forms became more widespread and it therefore seems worth while to give a popular summary of our present knowledge.
Hogback Tombstones and the Anglo-Danish House
Authors: Walton James 
Published: August 2016

In a number of publications W. G. Collingwood has described the north country hogbacks and he has suggested that they were replicas in stone of the dwellings prevailing at the time among the people responsible for their erection. He was primarily concerned, however, with their development and dating, based upon the ornament employed. In this paper I have concentrated rather on the hogback as a representation of an Anglo-Danish house and its bearing on the origin of cruck construction.The hogback is a recumbent tombstone in the form of a long, low house with a roofridge slightly arched lengthwise. Its ground plan (FIG. I, D) is bomb6 in shape, affording a plan which has only rarely been revealed by excavation. From Glendarragh, The Braaid, Isle of Man, Fleure and Dunlop have described two alignments which they consider represented the side walls of a boat-shaped house (FIG. I, A). These, they contend, were built of more durable materials to provide a stronger construction whilst the gable walls, which contained the entrances, were probably built of wattle. This is supported by the evidence of the hogbacks which show low stone ground-walls at the sides only and the walls at The Braaid are probably survivals of similar ground-walls. Fleure and Dunlop compare it to the ‘banqueting hall’ of Hofstaoir, Mývatn, in northern Iceland, which is 118 feet long and has incurved stone side walls varying from 19½ feet, at the ends, to 26 feet, in the middle, apart (FIG. I, B).
Olduvai Gorge and Human Origins
Authors: Napier J. R. , Weiner J. S. 
Published: August 2016

Nearly two years have passed since Dr L.S.B. Leakey announced the first of a series of remarkable discoveries at Olduvai Gorge, Tanganyika. The great importance of this region as a palaeontological hunting ground has been appreciated since 1911 when, by chance, a German entomologist picked up a number of fossil bones which had been eroded on to the surface of the slopes of this East African Pleistocene canyon. Since 1931 Dr Leakey has made repeated visits to the Gorge where steadily he has been building up the evidence of an early stone-age cultural sequence.In July, 1959, Dr and Mrs Leakey discovered a hominid skull which was lying partly exposed on the slopes, 22 ft. below the upper limit of Bed I, the lowest stratum of the Pleistocene sequence at Olduvai. Excavation of the site revealed that the skull was fragmented but almost complete and was lying on a living floor containing tools of a recognized culture (Oldowan) as well as waste flakes and unworked stones, all foreign to the site; in addition there were a number of broken and splintered bones of small animals which had apparently constituted part of the diet of the incumbents. Subsequently, a tibia and fibula were recovered from the same living floor. Dr Leakey named the skull Zinjanthropus boisei (PLATE x (a)). During 1960, excavations were started at a slightly lower level of Bed I and in December, 1960, Dr Leakey reported the discovery of a number of adult and juvenile bones of the hand and foot, two clavicles and some skull (parietal) fragments. This was rapidly followed by the important discovery of a juvenile mandible from the same level (PLATE XI). A number of stone artifacts of an Oldowan culture have also come to light from the juvenile site.
Civitas—A Myth?
Authors: Frere Sheppard 
Published: August 2016

Mr J. C. MANN holds that ‘each civitas of Gaul (and of Britain) was presumably a city, and like all true cities, each will have consisted of a single physical city surrounded by its territorium, the whole under the control of its magistrates, council and assembly, the last no doubt usually of little importance.’ I, on the other hand, following Jullian and Stevens, have suggested that the civitas was the whole tribal area, its capital (caput) normally ranking merely as a vicus where the government happened to have its seat. This, Mr Mann suggests, is a myth, which he doubts whether a Roman lawyer would understand.The evidence admittedly is not all that it might be; yet as the question is important for a correct understanding of the development of local government in Roman Britain (and elsewhere), I may venture to take it up once more, especially as Mr Mann’s note appears to me to be erroneous in one or two particulars, and to exhibit the triple weaknesses of a too narrowly legalistic outlook, an inadequate account of historical development, and a neglect of some of the relevant facts.
Across the Northe Sea: A Review
Authors: Megaw J. V. S. 
Published: August 2016

Exactly three centuries ago last year, Johan Picardt, parson of Coevorder in Drenthe and Adviser for Land-Reclamation, wrote in a regional study worthy of comparison with his contemporary John Aubrey’s Monumenta Britannica: ‘Our fore-fathers had not pen, ink, nor paper, which had they possessed would have enabled us to learn of strange things. Howsomever, they have bequeathed us signs enough if only it were that we could read them.’ Each one of the three volumes from the second of which my quotation comes clearly shows the ways in which archaeological research in the Low Countries has vindicated Picardt’s statement. Today archaeology in the Netherlands is a matter of exemplary close-knit co-operation between State institutions, universities, local societies, and the private individual, while recently Belgium has taken important steps in the systemization of pre- and protohistoric studies.Although the Low Countries can hardly be regarded as a primary area of development, their coastal position at the north-western limit of the transcontinental routes has made them a cultural entrepôt of particular significance for the British archaeologist. In this context Professor De Laet’s book in the ‘Ancient Peoples and Places’ series is all the more welcome in that it is the first English summary of the pre-Roman archaeology of the region.De Voorgeschiedenis der Lage Landen is a much expanded and corrected version of De Laet’s volume, with Professor Glasbergen’s collaboration giving a more balanced account of the Dutch evidence. The third book, a double volume of Antiquity and Survival, offers a lavishly illustrated symposium of one hundred centuries of the Netherlands, and although the promised English language edition is not to be, the Trustees of the Prince Bernhard Foundation and the Rijksdienst voor het Oudheidkundig Bodemonderzoek are to be warmly thanked for giving their support to Honderd Eeuwen Nederland.
Prehistoric Salt-Boiling
Authors: Riehm Karl 
Published: August 2016

Just over sfty years ago the puzzling Red Hills on the coast of Essex were arousing considerable interest among English prehistorians (PLATE XXII (a) and (b)). Already in the spring of 1906, under the chairmanship of J. Chalkley Gould and supported by the Essex Field Club, the Society of Antiquaries of London had formed a ‘Red Hills Exploration Committee’, which counted among its members not only archaeologists but also geologists, botanists and chemists, and had ample means at its disposal. Eminent specialists and scholars examined suitable hills with the utmost care and published their findings and conclusions in comprehensive papers.But in what consists the peculiarity and the riddle of these Red Hills, which obviously date back to prehistoric times and have since time immemorial lain in close proximity to the coast of England? The striking way in which they are built of loose red burnt clay unmistakably points to a human-made origin. As a rule these mounds rise by only as much as 18 in. to 6 ft. above their surroundings, and their extent varies between a few square yards to several hundred. How did these numerous and extensive heaps of burnt clay come about in prehistoric times?
The Cave of San Bartolomeo, Sardinia
Authors: Atzeni Enrico 
Published: August 2016

The results of the research carried out in these last years by the Istituto di Antichità Sarde e di Paletnologia of Cagliari University, particularly in Southern Sardinia, enable us to make a new and useful analysis of the stratigraphy of the cave of S. Bartolomeo, discovered and excavated by Orsoni in 1878 on the limestone promontory of Cape St. Elia at Cagliari, and re-explored by Patroni in 1901.The cave, as Childe has already pointed out, is the only place in Sardinia which up till now has provided the possibility of stratigraphical observations which (though still under discussion) nevertheless provide us with some reliable and objective data concerning the prehistoric cultures of pre-nuraghic date.Orsoni found a cavity measuring 5 m. × 4, completely filled from the roof to its rocky floor by an ancient deposit containing human and animal remains. The upper strata of this deposit were largely disturbed by modern graves, contained in a ditch walled in by ‘stones cemented with reddish mud’—and without any grave goods.
Grimsditch and Cuthwulf's Expedition to the Chilterns in A.D. 571
Authors: Hughes Michael W. 
Published: August 2016

In its original form this paper was prefaced with an account, painfully extracted from the somewhat unsatisfactory descriptions in the Historical Monuments Commission’s volumes for Herts and South Bucks and in the Victoria County History, of the existing portions of the earthwork with which I proposed to deal. For the South Oxfordshire Grimsditch, which I ventured to associate with the continuous work which runs through Herts and Bucks, I relied upon Plot and Burn, and some of the original documents used by the latter.As readers of ANTIQUITY are already aware, the Editor, moved by the conviction that the earnest seeker after truth in this field at least deserved to be supplied with the facts, has during the past two years personally investigated the whole of the remaining fragments of earthworks in the district, and I am therefore able to refer to his paper in the June number, and to the map which he has compiled to illustrate this paper as well as his own, as furnishing a succinct and authoritative statement of the main features of the Chiltern Grimsditch, by which my arguments stand or fall.
The Gods of Phoenicia as revealed by the Poem of Ras Shamra
Authors: Virolleaud Ch. 
Published: August 2016

Readers of ANTIQUITY are already aware that the second campaign at Ras Shamra—that of the spring of 1930—brought to light several new Phoenician texts. Amongst these pride of place must be given to ten fragments representing in all about a thousand lines of a kind of epic poem, whose various scenes are all laid in the world of the gods. The fragmentary state of the poem increases the difficulties of interpretation, which in any case would have been considerable ; nevertheless, by means of the careful analysis of certain episodes we can now form some sort of general conception of Phoenician mythology as it was about the time of the Ramessids and Amenophis (c. 16th-13th cent. B.c.). In the present article I propose to give a summary account of the results of my researches in this direction.The gods and goddesses thus brought to life again are more than fifty in number. But two stand out from amongst the rest, and these two are precisely those whom one would expect to find holding higher rank in a document emanating from Phoenicia-El and Baal.
Phytochrome B and REVEILLE1/2-mediated signalling controls seed dormancy and germination in Arabidopsis
Authors: Jiang Zhimin , Xu Gang , Jing Yanjun , Tang Weijiang , Lin Rongcheng 
Published: August 2016

AbstractSeeds maintain a dormant state to withstand adverse conditions and germinate when conditions become favourable to give rise to a new generation of flowering plants. Seed dormancy and germination are tightly controlled by internal and external signals. Although phytochrome photoreceptors are proposed to regulate primary seed dormancy, the underlying molecular mechanism remains elusive. Here we show that the REVEILLE1 (RVE1) and RVE2 transcription factors promote primary seed dormancy and repress red/far-red-light-reversible germination downstream of phytochrome B (phyB) in Arabidopsis thaliana. RVE1 and RVE2 expression is downregulated after imbibition and by phyB. RVE1 directly binds to the promoter of GIBBERELLIN 3-OXIDASE 2, inhibits its transcription and thus suppresses the biosynthesis of bioactive gibberellins. In addition, DELAY OF GERMINATION 1 also acts downstream of phyB. This study identifies a signalling pathway that integrates environmental light input with internal factors to control both seed dormancy and germination.
Taming contact line instability for pattern formation
Authors: Deblais A. , Harich R. , Colin A. , Kellay H. 
Published: August 2016

AbstractCoating surfaces with different fluids is prone to instability producing inhomogeneous films and patterns. The contact line between the coating fluid and the surface to be coated is host to different instabilities, limiting the use of a variety of coating techniques. Here we take advantage of the instability of a receding contact line towards cusp and droplet formation to produce linear patterns of variable spacings. We stabilize the instability of the cusps towards droplet formation by using polymer solutions that inhibit this secondary instability and give rise to long slender cylindrical filaments. We vary the speed of deposition to change the spacing between these filaments. The combination of the two gives rise to linear patterns into which different colloidal particles can be embedded, long DNA molecules can be stretched and particles filtered by size. The technique is therefore suitable to prepare anisotropic structures with variable properties.
A Dynamical Analysis of the Suitability of Prehistoric Spheroids from the Cave of Hearths as Thrown Projectiles
Authors: Wilson Andrew D. , Zhu Qin , Barham Lawrence , Stanistreet Ian , Bingham Geoffrey P. 
Published: August 2016

AbstractSpheroids are ball-shaped stone objects found in African archaeological sites dating from 1.8 million years ago (Early Stone Age) to at least 70,000 years ago (Middle Stone Age). Spheroids are either fabricated or naturally shaped stones selected and transported to places of use making them one of the longest-used technologies on record. Most hypotheses about their use suggest they were percussive tools for shaping or grinding other materials. However, their size and spherical shape make them potentially useful as projectile weapons, a property that, uniquely, humans have been specialised to exploit for millions of years. Here we show (using simulations of projectile motions resulting from human throwing) that 81% of a sample of spheroids from the late Acheulean (Bed 3) at the Cave of Hearths, South Africa afford being thrown so as to inflict worthwhile damage to a medium-sized animal over distances up to 25 m. Most of the objects have weights that produce optimal levels of damage from throwing, rather than simply being as heavy as possible (as would suit other functions). Our results show that these objects were eminently suitable for throwing, and demonstrate how empirical research on behavioural tasks can inform and constrain our theories about prehistoric artefacts.
High density genome wide genotyping-by-sequencing and association identifies common and low frequency SNPs, and novel candidate genes influencing cow milk traits

Published: August 2016

AbstractHigh-throughput sequencing technologies have increased the ability to detect sequence variations for complex trait improvement. A high throughput genome wide genotyping-by-sequencing (GBS) method was used to generate 515,787 single nucleotide polymorphisms (SNPs), from which 76,355 SNPs with call rates >85% and minor allele frequency ≥1.5% were used in genome wide association study (GWAS) of 44 milk traits in 1,246 Canadian Holstein cows. GWAS was accomplished with a mixed linear model procedure implementing the additive and dominant models. A strong signal within the centromeric region of bovine chromosome 14 was associated with test day fat percentage. Several SNPs were associated with eicosapentaenoic acid, docosapentaenoic acid, arachidonic acid, CLA:9c11t and gamma linolenic acid. Most of the significant SNPs for 44 traits studied are novel and located in intergenic regions or introns of genes. Novel potential candidate genes for milk traits or mammary gland functions include ERCC6, TONSL, NPAS2, ACER3, ITGB4, GGT6, ACOX3, MECR, ADAM12, ACHE, LRRC14, FUK, NPRL3, EVL, SLCO3A1, PSMA4, FTO, ADCK5, PP1R16A and TEP1. Our study further demonstrates the utility of the GBS approach for identifying population-specific SNPs for use in improvement of complex dairy traits.
Optical characterization of Tm3+ doped Bi2O3-GeO2-Ga2O3 glasses in absence and presence of BaF2

Published: August 2016

AbstractIn this paper, Two new Bi2O3-GeO2-Ga2O3 glasses (one presence of BaF2) doped with 1mol% Tm2O3 were prepared by melt-quenching technique. Differential thermal analysis (DTA), the absorption, Raman, IR spectra and fluorescence spectra were measured. The Judd–Ofelt intensity parameters, emission cross section, absorption cross section, and gain coefficient of Tm3+ ions were comparatively investigated. After the BaF2 introduced, the glass showed a better thermal stability, lower phonon energy and weaker OH− absorption coefficient, meanwhile, a larger ~1.8 μm emission cross section σem (7.56 × 10−21 cm2) and a longer fluorescence lifetime τmea (2.25 ms) corresponding to the Tm3+: 4F3 → 3H6 transition were obtained, which is due to the addition of fluoride in glass could reduce the quenching rate of hydroxyls and raise the cross-relaxation (3H6 + 3H4 → 3F4 + 3F4) rate. Our results suggest that the Tm3+ doped Bi2O3-GeO2-Ga2O3 glass with BaF2 might be potential to the application in efficient ~1.8 μm lasers system.

AbstractGiven that reduced graphene oxide (rGO)-based biosensors allow disposable and repeatable biomarker detection at the point of care, we developed a wafer-scale rGO patterning method with mass productivity, uniformity, and high resolution by conventional micro-electro-mechanical systems (MEMS) techniques. Various rGO patterns were demonstrated with dimensions ranging from 5 μm up to several hundred μm. Manufacture of these patterns was accomplished through the optimization of dry etching conditions. The axis-homogeneity and uniformity were also measured to verify the uniform patternability in 4-inch wafer with dry etching. Over 66.2% of uniform rGO patterns, which have deviation of resistance within range of ±10%, formed the entire wafer. We selected amyloid beta (Aβ) peptides in the plasma of APP/PS1 transgenic mice as a study model and measured the peptide level by resistance changes of highly uniform rGO biosensor arrays. Aβ is a pathological hallmark of Alzheimer’s disease and its plasma concentration is in the pg mL−1 range. The sensor detected the Aβ peptides with ultra-high sensitivity; the LOD was at levels as low as 100 fg mL−1. Our results provide biological evidences that this wafer-scale high-resolution patterning method can be used in rGO-based electrical diagnostic devices for detection of low-level protein biomarkers in biofluids.
Systematic assessment of pharmaceutical prescriptions in association with cancer risk: a method to conduct a population-wide medication-wide longitudinal study

Published: August 2016

AbstractIt is a public health priority to identify the adverse and non-adverse associations between pharmaceutical medications and cancer. We search for and evaluate associations between all prescribed medications and longitudinal cancer risk in participants of the Swedish Cancer Register (N = 9,014,975). We associated 552 different medications with incident cancer risk (any, breast, colon and prostate) during 5.5 years of follow-up (7/1/2005-12/31/2010) in two types of statistical models, time-to-event and case-crossover. After multiple hypotheses correction and replication, 141 (26%) drugs were associated with any cancer in a time-to-event analysis constraining drug exposure to 1 year before first cancer diagnosis and adjusting for history of medication use. In a case-crossover analysis, 36 drugs (7%) were associated with decreased cancer risk. 12 drugs were found in common in both analyses with concordant direction of association. We found 14, 10, 7% of all drugs associated with colon, prostate and breast cancers in time-to-event models. We only found 1, 2% and 0% for these cancers, respectively, in case-crossover analyses. Pharmacoepidemiologic analyses of cancer risk are sensitive to modeling choices and false-positive findings are a threat. Medication-wide analyses using different analytical models may help suggest consistent signals of increased cancer risk.
Topological spin and valley pumping in silicene
Authors: Luo Wei , Sheng L. , Wang B. G. , Xing D. Y. 
Published: August 2016

AbstractWe propose to realize adiabatic topological spin and valley pumping by using silicene, subject to the modulation of an in-plane ac electric field with amplitude Ey and a vertical electric field consisting of an electrostatic component and an ac component with amplitudes "Equation missing" and "Equation missing". By tuning "Equation missing" and "Equation missing", topological valley pumping or spin-valley pumping can be achieved. The low-noise valley and spin currents generated can be useful in valleytronic and spintronic applications. Our work also demonstrates that bulk topological spin or valley pumping is a general characteristic effect of two-dimensional topological insulators, irrelevant to the edge state physics.
