The great number of replicas of the youthful Athena known as the Rospigliosi type proves that the original was a famous statue. The bad state of preservation as well as variations in the different copies have made it difficult to date the original; the lack of good reproductions has also caused misunderstandings and has led astray the scholars who have dealt with the type. I think it necessary, therefore, to publish here a Hermitage fragment of very good workmanship, which is untouched and unrestored by any modern master. I shall not here undertake to explain the strange attributes—stars on the aegis, sea-monster in the Rospigliosi statue; the present purpose is merely to fix the date of the original.The fragment reproduced here for the first time in fairly good photographs (Plates VII., VIII.) was found in 1823 in the so-called Vigna del Collegio Inglese on the Palatine at Rome, and formed part of the Museo Campana until 1861. The Emperor Alexander II bought a part of this collection for the Hermitage; among these marbles the fragment of the Athena statue found its way to the then newly-arranged Museum of Ancient Sculpture. Being only a fragment it was exhibited in a rather dark corner and could not be sufficiently well studied. A rough drawing in Gerhard's Antike Denkmäler and a very small illustration in Kieseritzky's Catalogue of 1901 were the only accessible publications.

Abstract We consider for the first time level 7 modular invariant flavour models where the lepton mixing originates from the breaking of modular symmetry and couplings responsible for lepton masses are modular forms. The latter are decomposed into irreducible multiplets of the finite modular group Γ7, which is isomorphic to PSL(2, Z7), the projective special linear group of two dimensional matrices over the finite Galois field of seven elements, containing 168 elements, sometimes written as PSL2(7) or Σ(168). At weight 2, there are 26 linearly independent modular forms, organised into a triplet, a septet and two octets of Γ7. A full list of modular forms up to weight 8 are provided. Assuming the absence of flavons, the simplest modular-invariant models based on Γ7 are constructed, in which neutrinos gain masses via either the Weinberg operator or the type-I seesaw mechanism, and their predictions compared to experiment.

On January 12th, 1732, John Horsley, Presbyterian divine and schoolmaster, died suddenly at Morpeth at the early age of 46. The following March or April witnessed the publication of his great book, in which real scholarship was for the first time brought to bear upon the interpretation of Romano-British antiquities. The occurrence of this double bicentenary seems to provide an appropriate opportunity for reminding readers of the Journal of the magnitude of the achievement represented by the Britannia Romana. A fully documented account of the author's career, together with an estimate of the value of his work, will appear in the forthcoming volume of Archaeologia Aeliana. For the present purpose, therefore, a brief summary will suffice.

AbstractNon-orthodox Christian asceticism in Late Antiquity is known to us largely through the distorting lens of orthodox heresiology. This paper aims to reassess the character of the ascetic communities of rural Lycaonia in the fourth century a.d. in the light of the surviving funerary and ecclesiastical epigraphy, including three inscriptions published here for the first time. We are fortunate to be able to read these texts in the light of a neglected work of orthodox polemic, Amphilochius’ Against False Asceticism, the work of an embattled orthodox bishop at Iconium in the late 370s a.d. This treatise formed part of a successful campaign to stigmatize the Lycaonian ascetics as heretics, a position which was enshrined in Theodosius’ anti-heretical legislation of a.d. 381–3.

Looseness is a defect found in leather that reduces its quality by causing a wrinkly appearance in the finished product, resulting in a reduction in its value. Earlier studies on loose leather using microscopy and Raman spectroscopy reported a change in the collagen structure of loose leather. In this study, proteomics was used to investigate the possible molecular causes of looseness in the raw material, the first time such a study has been carried out. Proteins extracted from two regions of raw hide using two different methods were analysed; those taken from the distal axilla, an area prone to looseness, and those taken from the backbone which is less prone to looseness. Analyses using 1DE-LC-MS/MS showed that although the overall collagen concentration was similar in both areas of the hide, the distribution of the different types of collagen differed.  Specifically, concentrations of type I collagen, and the collagen-associated proteoglycan decorin were lower in samples taken from the distal axilla, symptomatic of a collagen network with excess space seen for these samples using confocal microscopy. This study suggests a possible link between the molecular components of raw cattle hide and looseness and more importantly between the molecular components of skin and skin defects. There is therefore potential to develop biomarkers for looseness which will enable early preventative action.

Congenital heart diseases are common cause of congenital cyanosis with polycythaemia. Congenital methemoglobinemia is a rare cause of lifelong cyanosis with polycythemia. Congenital methemoglobinemia is caused either by enzyme deficiency or by an abnormal Hb (Hb M). Asymptomatic despite presence of severe cyanosis indicates this rare disorder. We are reporting a rare case of polycythemia with cyanosis due to congenital methemoglobinemia. The patient was referred to our centre and attended Hematology OPD (out-patient department) when his routine CBC revealed erythrocytosis. At that time, we found him severely cyanosed especially apparent on lips, tongue, hands and feet. He was diagnosed as a case of congenital methemoglobinemia with 38% blood methemoglobin level (normal value-0.00-2.00%). On view of life long persistent cyanosis, without any cardiopulmonary and neurological abnormality, consanguinity of parent’s marriage, dark colored blood with high methemoglobin level, a final diagnosis of Type I enzyme deficiency congenital methemoglobinemia was made. He was treated with oral ascorbic acid 250 mg twice daily. At follow up after 6 months his skin color improved and RBC count returned to normal. We are reporting this case of congenital methemoglobinemia for the first time in Bangladesh to emphasize the importance of this rare entity in the differential diagnosis of asymptomatic cyanosis with polycythemia.

ABSTRACT Contrast analysis has become prevalent in experimental accounting research since Buckless and Ravenscroft (1990) introduced it to the accounting literature over 25 years ago. Since its initial introduction, the scope of contrast testing has expanded, yet guidance as to the most appropriate methods of specifying, conducting, interpreting, and exhibiting these tests has not. We survey the use of contrast analysis in the recent literature and propose a three-part testing approach that provides a more comprehensive picture of contrast results. Our approach considers three pieces of complementary evidence: the visual evaluation of fit, traditional significance testing, and quantitative evaluation of the contrast variance residual. Our measure of the contrast variance residual, q2, is proposed for the first time in this work. After proposing our approach, we walk through six common contrast testing scenarios where current practices may fall short and our approach may guide researchers. We extend Buckless and Ravenscroft (1990) and contribute to the accounting research methods literature by documenting current contrast analysis practices that result in elevated Type I error and by proposing a potential solution to mitigate these concerns.

ABSTRACTWe have synthesized the type II silicon clathrates Na1Si136 and Na8Si136, and report on the electrical and thermal transport in these materials. The crystal structure consists of a covalently bonded silicon framework in which sodium guest atoms are encapsulated inside the silicon host framework. Differential scanning calorimetry measurements show the compounds decompose above 600°C to diamond-structure silicon. Temperature dependant electrical resistivity measurements show the specimens to have an insulating character, with magnitudes that decrease with increasing sodium content. For the first time, thermal conductivity measurements on type II sodium-silicon clathrates are presented. The thermal conductivity is very low for both specimens, and for Na8Si136 exhibits a clear dip in the range from 50 to 70 K. These data suggest that the “rattling” behavior observed in type I clathrates may also be present in type II clathrates.

Burst Emission

Type I X-ray bursts in GS 1826–24, and in several other systems, may induce cooling of the hot inner accretion flow that surrounds the bursting neutron star. Given that GS 1826–24 remained persistently in the hard state over the period 2003–2008 and presented regular bursting properties, we stacked the spectra of the X-ray bursts detected by INTEGRAL (JEM-X and ISGRI) and XMM-Newton (RGS) during that period to study the effect of the burst photons on the properties of the Comptonizing medium. The extended energy range provided by these instruments allows the simultaneous observation of the burst and persistent emission spectra. We detect an overall change in the shape of the persistent emission spectrum in response to the burst photon shower. For the first time, we observe simultaneously a drop in the hard X-ray emission, together with a soft X-ray excess with respect to the burst blackbody emission. The hard X-ray drop can be explained by burst-induced coronal cooling, while the bulk of the soft X-ray excess can be described by fitting the burst emission with an atmosphere model, instead of a simple blackbody model. Traditionally, the persistent emission was assumed to be invariant during X-ray bursts, and more recently to change only in normalization but not in spectral shape; the observed change in the persistent emission level during X-ray bursts may thus trigger the revision of existing neutron star mass-radius constraints, as the derived values rely on the assumption that the persistent emission does not change during X-ray bursts. The traditional burst fitting technique leads to up to a 10% overestimation of the bolometric burst flux in GS 1826–24, which significantly hampers the comparisons of the KEPLER and MESA model against this “textbook burster”.

Purpose This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies. Design/methodology/approach This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings The year 2016 will in part be remembered, like all years divisible by four since 1896, by the Olympic spectacle that emanated for the first time from Brazil’s most famous city, Rio de Janeiro. But will it be the success, or the scandal that lingers longest in the memory? As with all modern Olympics, it was a blend of astonishing achievements, colorful celebration and sudden scandals – banned athletes, drug cheats, badly behaved swimmers and dodgy decisions all formed part of the rich canvas that enthralls millions each time it is held. Practical implications The paper provides strategic insights and practical thinking that have influenced some of the world’s leading organizations. Originality/value The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

ABSTRACT Most of the intracellular pattern recognition receptors (PRRs) reside in either the endolysosome or the cytoplasm to sense pathogen-derived RNAs, DNAs, or synthetic analogs of double-stranded RNA (dsRNA), such as poly(I:C). However, it remains elusive whether or not a pathogen-derived protein can function as a cytosolic pathogen-associated molecular pattern (PAMP). In this study, we demonstrate that delivering the membrane gene of severe acute respiratory syndrome coronavirus (SARS-CoV) into HEK293T, HEK293ET, and immobilized murine bone marrow-derived macrophage (J2-Mφ) cells significantly upregulates beta interferon (IFN-β) production. Both NF-κB and TBK1-IRF3 signaling cascades are activated by M gene products. M protein rather than M mRNA is responsible for M-mediated IFN-β induction that is preferentially associated with the activation of the Toll-like receptor (TLR) adaptor proteins MyD88, TIRAP, and TICAM2 but not the RIG-I signaling cascade. Blocking the secretion of M protein by brefeldin A (BFA) failed to reverse the M-mediated IFN-β induction. The antagonist of both TLR2 and TLR4 did not impede M-mediated IFN-β induction, indicating that the driving force for the activation of IFN-β production was generated from inside the cells. Inhibition of TRAF3 expression by specific small interfering RNA (siRNA) did not prevent M-mediated IFN-β induction. SARS-CoV pseudovirus could induce IFN-β production in an M rather than M(V68A) dependent manner, since the valine-to-alanine alteration at residue 68 in M protein markedly inhibited IFN-β production. Overall, our study indicates for the first time that a pathogen-derived protein is able to function as a cytosolic PAMP to stimulate type I interferon production by activating a noncanonical TLR signaling cascade in a TRAF3-independent manner. IMPORTANCE Viral protein can serve as a pathogen-associated molecular pattern (PAMP) that is usually recognized by certain pathogen recognition receptors (PRRs) on the cell surface, such as Toll-like receptor 2 (TLR2) and TLR4. In this study, we demonstrate that the membrane (M) protein of SARS-CoV can directly promote the activation of both beta interferon (IFN-β) and NF-κB through a TLR-related signaling pathway independent of TRAF3. The driving force for M-mediated IFN-β production is most likely generated from inside the cells. M-mediated IFN-β induction was confirmed at the viral infection level since a point mutation at the V68 residue of M markedly inhibited SARS-CoV pseudovirally induced IFN-β production. Thus, the results indicate for the first time that SARS-CoV M protein may function as a cytosolic PAMP to stimulate IFN-β production by activating a TLR-related TRAF3-independent signaling cascade.
