The effect of root and bone visualization on perceptions of the quality of orthodontic treatment simulations
Authors: Grünheid Thorsten , Kirk Danae C. , Larson Brent E. 
Published: November 2016

ABSTRACTObjective:To evaluate the effect of root and bone visibility on orthodontists' perceptions of the quality of treatment simulations.Material and Methods:An online survey was used to present orthodontists with setups generated for 10 patients in two different types of view: with and without bone and roots as modeled from a cone-beam computed tomography (CBCT) scan. The orthodontists were asked to rate the quality of the setups from poor to ideal on a 100-point visual analog scale and, if applicable, to identify features of concern that led them to giving a setup a less-than-ideal rating.Results:The quality ratings were significantly lower when roots and bone were visible in the setups (P &lt; .0001). Buccolingual inclination and periodontal concerns were selected significantly more often as reasons for a less-than-ideal rating when roots and bone were shown, whereas occlusal relationship, overjet, occlusal contacts, and arch form were selected significantly more often as reasons for a less-than-ideal rating when roots and bone were not shown. The odds of selecting periodontal concerns as a reason for a less-than-ideal setup rating were 331 times greater when roots and bones were visible than when they were not.Conclusions:Additional diagnostic information derived from CBCT scans affects orthodontists' perceptions of the overall case quality, which may influence their treatment-planning decisions.
Association between Severity of Tooth Wear and Dentinal Hypersensitivity
Authors: Ayer Ashok 
Published: November 2016

Background & Objectives: Tooth wear (attrition, abrasion, erosion, and abfraction) is perceived globally as ever increasing problem. Several outcome of the tooth wear are hypersensitivity, esthetic problems, functional impairment, annoyance to the patient, and fracture of the tooth. Among these, the measurable and more commonly reported outcome is hypersensitivity to stimuli. Although dentin hypersensitivity is a common clinical condition and is generally reported by the patient after experiencing a sharp, short pain caused by one of the several different external stimuli, it is often inadequately understood. None of the scientific literature available till date attempted to establish the relationship between tooth wear and dentin hypersensitivity which could be a key factor in monitoring those patients. The aim of the study was to estimate the association between severity of teeth wear and sensitivity in the patients with reported dentinal hypersensitivity.Materials & Methods: Fifty patients with dentin hypersensitivity were investigated for tooth wear. Tooth wear measured using exact tooth wear index and level of sensitivity to stimuli was recorded using a numerical rating scale. Results: Enamel wear at cervical region of teeth showed a positive correlation (p=.010), similarly, dentin wear at cervical region of teeth showed positive correlation and significant association (p<.001) with dentinal hypersensitivity.Conclusion: The observation supports a significant association between severities of tooth surface wear and dentinal hypersensitivity.

Exploration of the archaic sanctuary at Mandra on the island of Despotiko
p. 133-174
The results are presented of the archaeological excavation at the site of Mandra on Despotiko, an uninhabited island west of Paros and Antiparos. Initial investigations of surface material led to a full scale excavation centring on Building A, a large structure consisting of five parallel rooms, which may have been a hestiatorion. The general status of the site as a sanctuary is confirmed by numerous votive finds. The majority of artefacts recovered thus far date to the Archaic period, including sculptural fragments, imported ceramics, and a wide range of metal objects and small finds. Architectural members, most of which were rebuilt into later structures, indicate the presence of several other Doric buildings on the site, and a long stone wall encloses a large area east of Building A. The name Apollo inscribed on sherds suggests that this sanctuary was dedicated to the god. The feminine nature of many ex-votos and the presence of several Delian sanctuaries throughout the Cyclades, however, may indicate that Artemis was also worshipped there.

H πύλη του Δία στη Θάσο

Η πύλη του Δία και της Ήρας στη Θάσο, προσφορά του Πύθιππου, γιου του Παιεστράτου, αποτελεί ένα από τα πιο αξιοσημείωτα στοιχεία του τείχους της Θάσου: εκτός από τα ανάγλυφα που τη διακοσμούσαν, έφερε και συγκεκριμένο, πρωτότυπο αρχιτεκτονικό διάκοσμο, ο οποίος δεν έχει ποτέ αναλυθεί στο σύνολο του. Η ύπαρξη κατά χώραν πολλών τμημάτων επιτρέπει την σχεδιαστική αναπαράσταση της πύλης
— στην πραγματικότητα μια πύργος-πύλη — , με επάλληλους αρχιτεκτονικούς ρυθμούς
— δωρικό και ιωνικό — στην όψη της προς την πόλη και δωρική ζωφόρο ενσωματωμένη στους τοίχους του πύργου στην όψη της προς την ύπαιθρο. Οι επιρροές της ταφικής και ανακτορικής μακεδονικής αρχιτεκτονικής είναι εμφανείς. Σύμφωνα με τους καταλόγους των θεωρών και τις σφραγίδες των αμφορέων που βρέθηκαν στα προγένεστερα στρώματα, η πύργος-πύλη αυτή κατασκευάστηκε γύρω στο 300 π. Χ. Διαδέχθηκε ένα αρχικό άνοιγμα, το οποίο χρονολογείται από την εποχή κατά την οποία χτίστηκε το σήμερα ορατό τείχος, δηλαδή ύστερα από την επιδρομή του Ιστιαίου της Μιλήτου εναντίον της Θάσου, το 494- Τόσο οι παλαιότερες ανασκαφές όσο και οι πρόσφατες έρευνες επιβεβαιώνουν τη μαρτυρία του Ηρόδοτου (VI 46), η οποία και δεν υπάρχει λόγος να αμφισβητηθεί.

En visitant et revisitant les ateliers amphoriques de Thasos
p. 269-329
L'article fait le bilan des recherches sur les ateliers amphoriques de Thasos entreprises en 1977 et présente, sous forme de tableaux commentés et abondamment illustrés, les milliers de timbres qui en sont issus. Les dernières fouilles réalisées au Molos par le service archéologique ont fourni un matériel particulièrement abondant (plus de 3 000 exemplaires) et riche en indications sur les variantes de matrices et l'impression des cachets entre le dernier tiers du IVe siècle et le début de la seconde moitié du IIIe siècle. Le dépotoir de Chioni, fouillé en 1995 par l'École française d'Athènes, se scinde en deux ensembles : le premier contenant une cinquantaine de timbres «anciens » du milieu du IVe siècle et le second plus de 400 timbres «récents » qui mentionnent 85 éponymes postérieurs aux environs de 320. Chaque année, de 1978 à 2003, les sites connus ou présumés de production amphorique ont été l'objet de collectes de surface qui ont permis d'esquisser ou de compléter leur étude. La classification chronologique des magistrats amphoriques de Thasos a été revue en conséquence, sous forme d'un tableau argumenté, du début du timbrage «récent » (qui devrait se dater des environs de 333 av. J.-C.) jusque vers 210 (plusieurs décennies sans doute avant sa disparition).

Από χρυσό και μάρμαρο: τα επιχρυσωμένα ελληνιστικά γλυπτά της Δήλου
σ. 331-349
Οι έρευνες που διεξάγουμε ως προς την πολυχρωμία των ελληνιστικών γλυπτών της Δήλου μας επέτρεψαν να εμπλουτίσουμε το κύριο corpus των επιχρυσωμένων μαρμάρινων γλυπτών με νέα στοιχεία, αλλά και να τα προσδιορίσουμε τυπολογικά. Η οπτική εξέταση των γλυπτών στο βιντεομικροσκόπιο, σε συνδυασμό με την ανάλυση με φθοριούχος ακτινοβολία Χ των κατάλοιπων που απομονώσαμε με τον παραπάνω τρόπο, έφεραν στο φως τρεις βασικούς τύπους επιχρύσωσης με φύλλο χρυσού στη Δήλο, γύρω στο ιοο π. Χ.: τα επιχρυσωμένα αγάλματα, τα έργα στα οποία η επιχρύσωση δεν αποτελεί παρά έναν λαμπερό χρωματισμό στο πλαίσιο της γενικότερης πολυχρωμίας και τα έργα που προτείνουμε να ονομάσουμε « chrysochromes »· τα τελευταία παρουσιάζουν μια ιδιαιτερότητα που δεν είχε αναγνωριστεί έως τώρα, δηλ. συνδυάζουν την έντονη πολυχρωμία των ενδεδυμένων τμημάτων με το χρυσό χρώμα των γυμνών τμημάτων. Μεταξύ των σημαντικών αποτελεσμάτων μιας τέτοιας έρευνας συγκαταλέγεται και η ανακάλυψη ολικής επιχρύσωσης με φύλλο χρυσού στο δηλιακό αντίγραφο που φυλάσσεται στο Εθνικό Αρχαιολογικό Μουσείο στην Αθήνα του Διαδούμενου του Πολύκλειτου, επιχρυσωμένο με φύλλο χρυσού, κατά το πρότυπο επιχρυσωμένου χάλκινο αγάλματος, ή αγάλματος από χρυσό. Μια τέτοια χρήση της τεχνικής της επιχρύσωσης με φύλλο χρυσού στα δηλιακά αγάλματα απαίτει επανεξέταση του ζητήματος της αποδοχής αυτών των έργων στην αρχαιότητα και της επιτυχίας που είχε ο χρυσός στη Δήλο, όπως, αναμφισβήτητα, και σε άλλες περιοχές του ελληνικού κόσμου κατά την ίδια χρονική περίοδο.

À la recherche d'un bain romain dans la région de Malia
p. 607-627
On aborde ici l'importance de l'activité romaine dans la région de Malia et on examine l'éventualité de la présence d'un bain romain (public ou privé, mais plus vraisemblablement privé) dans la zone du marais. L'identification de trois clous d'espacement en terre cuite et de plusieurs fragments de pilae recueillis lors de la prospection de Malia, près de la basilique, suggère l'existence d'un bain romain dans les environs, quelque part dans le marais (probablement dans la région de la basilique). La présence de clous d'espacement en terre cuite dans l'arrière-pays maliote est révélatrice, puisque leur usage est presque exclusivement associé à des bains romains, ailleurs dans l'Orient romain (généralement datés des IIe et IIIe siècles apr. J.-C.).
Tucidide e l'anfizionia di Delfi
Authors: Mari Manuela 
Published: November 2016

L'amphictionie delphique est absente des Histoires de Thucydide. On présente ici tous les événements qui s'inscrivent dans le champ historique de Thucydide, dans lesquels l'amphictionie a pu jouer un rôle ou dont le rôle est attesté par d'autres sources : dans quelques cas, le silence de Thucydide s'explique par les exigences et le rythme de la narration et par les critères adoptés pour la sélection des faits à raconter ; dans d'autres, il reflète l'absence effective de l'amphictionie dans la «grande histoire».
La non mention de l'amphictionie ne prouve pas le manque d'intérêt de Thucydide pour les facteurs religieux au cours de l'histoire. Il conserve en effet des informations importantes sur l'histoire de Delphes au Ve siècle, lorsqu'elles s'inscrivent dans la ligne, politico-militaire essentiellement, de son analyse historique. L'amphictionie ne fut jamais un instrument direct du pouvoir, même si elle réussit, dans certaines circonstances, à jouer un rôle politique indirect, le plus souvent sous la tutelle des puissants Etats pilotes. L'intérêt divers des historiens des Ve et IVe siècles pour l'amphictionie s'explique ainsi, à la lumière de cette discontinuité effective de son rôle «politique».
LIGHT CURVE SOLUTIONS OF 12 ECCENTRIC KEPLER BINARIES AND ANALYSIS OF THEIR OUT-OF-ECLIPSE VARIABILITY
Authors: Kjurkchieva Diana , Vasileva Doroteya , Dimitrov Dinko 
Published: November 2016

ABSTRACT
The eccentricity, periastron angle, orbital inclination, mass ratio, stellar temperatures, and relative stellar radii of 12 eclipsing eccentric binaries were determined on the basis of Kepler data. The analysis of their out-of-eclipse variability led to the following results: (i) KIC 10490980 exhibits rotational (spot-type) variability. (ii) Four new heartbeat stars were found: KIC 9344623 and KIC 10296163, which have wide tidally induced light humps, and KIC 9119405 and KIC 9673173, which have narrow “W-shape” features. (iii) KIC 4932691 shows oscillations with approximately the 18th harmonic of the orbital period. We established that the eccentric Kepler binaries fall below the envelope

days on the period–eccentricity diagram and that there is a surprising lack of eccentric binaries with periods of 25–35 days.
PROXIMA CENTAURI AS A BENCHMARK FOR STELLAR ACTIVITY INDICATORS IN THE NEAR-INFRARED
Authors: Robertson Paul , Bender Chad , Mahadevan Suvrath , Roy Arpita , Ramsey Lawrence W. 
Published: November 2016

ABSTRACT
A new generation of dedicated Doppler spectrographs will attempt to detect low-mass exoplanets around mid- to late M stars at near-infrared (NIR) wavelengths, where those stars are brightest and have the most Doppler information content. A central requirement for the success of these instruments is to properly measure the component of radial velocity (RV) variability contributed by stellar magnetic activity and to account for it in exoplanet models of RV data. The wavelength coverage for many of these new instruments will not include the Ca ii H&K or Hα lines, the most frequently used absorption-line tracers of magnetic activity. Thus, it is necessary to define and characterize NIR activity indicators for mid- to late M stars in order to provide simultaneous activity metrics for NIR RV data. We have used the high-cadence UVES observations of the M5.5 dwarf Proxima Centauri from Fuhrmeister et al. to compare the activity sensitivity of eight NIR atomic lines to that of Hα. We find that equivalent-width-type measurements of the NIR K i doublet and the Ca ii NIR triplet are excellent proxies for the canonical optical tracers. The Ca ii triplet will be acquired by most of the new and upcoming NIR Doppler spectrographs, offering a common, reliable indicator of activity.

ABSTRACT
We present Chandra ACIS-S and Australia Telescope Compact Array (ATCA) radio continuum observations of the strongly lensed dusty, star-forming galaxy SPT-S J034640-5204.9 (hereafter SPT0346-52) at z = 5.656. This galaxy has also been observed with ALMA, HST, Spitzer, Herschel, Atacama Pathfinder EXperiment, and the Very Large Telescope. Previous observations indicate that if the infrared (IR) emission is driven by star formation, then the inferred lensing-corrected star formation rate (SFR) (∼4500 M
☉ yr−1) and SFR surface density ΣSFR (∼2000 M
☉ yr−1 kpc−2) are both exceptionally high. It remained unclear from the previous data, however, whether a central active galactic nucleus (AGN) contributes appreciably to the IR luminosity. The Chandra upper limit shows that SPT0346-52 is consistent with being star formation dominated in the X-ray, and any AGN contribution to the IR emission is negligible. The ATCA radio continuum upper limits are also consistent with the FIR-to-radio correlation for star-forming galaxies with no indication of an additional AGN contribution. The observed prodigious intrinsic IR luminosity of (3.6 ± 0.3) × 1013
L
☉ originates almost solely from vigorous star formation activity. With an intrinsic source size of 0.61 ± 0.03 kpc, SPT0346-52 is confirmed to have one of the highest ΣSFR of any known galaxy. This high ΣSFR, which approaches the Eddington limit for a radiation pressure supported starburst, may be explained by a combination of very high star formation efficiency and gas fraction.
WHY ARE PULSAR PLANETS RARE?
Authors: Martin Rebecca G. , Livio Mario , Palaniswamy Divya 
Published: November 2016

ABSTRACT
Pulsar timing observations have revealed planets around only a few pulsars. We suggest that the rarity of these planets is due mainly to two effects. First, we show that the most likely formation mechanism requires the destruction of a companion star. Only pulsars with a suitable companion (with an extreme mass ratio) are able to form planets. Second, while a dead zone (a region of low turbulence) in the disk is generally thought to be essential for planet formation, it is most probably rare in disks around pulsars, because of the irradiation from the pulsar. The irradiation strongly heats the inner parts of the disk, thus pushing the inner boundary of the dead zone out. We suggest that the rarity of pulsar planets can be explained by the low probability for these two requirements to be satisfied: a very low-mass companion and a dead zone.

ABSTRACT
We present the H i mass inventory for the REsolved Spectroscopy Of a Local VolumE (RESOLVE) survey, a volume-limited, multi-wavelength census of >1500 z = 0 galaxies spanning diverse environments and complete in baryonic mass down to dwarfs of ∼109

. This first 21 cm data release provides robust detections or strong upper limits (1.4M
H i
< 5%–10% of stellar mass M
*) for ∼94% of RESOLVE. We examine global atomic gas-to-stellar mass ratios (G/S) in relation to galaxy environment using several metrics: group dark matter halo mass M
h, central/satellite designation, relative mass density of the cosmic web, and distance to the nearest massive group. We find that at fixed M
*, satellites have decreasing G/S with increasing M
h starting clearly at M
h ∼ 1012

, suggesting the presence of starvation and/or stripping mechanisms associated with halo gas heating in intermediate-mass groups. The analogous relationship for centrals is uncertain because halo abundance matching builds in relationships between central G/S, stellar mass, and halo mass, which depend on the integrated group property used as a proxy for halo mass (stellar or baryonic mass). On larger scales G/S trends are less sensitive to the abundance matching method. At fixed M
h ≤ 1012

, the fraction of gas-poor centrals increases with large-scale structure density. In overdense regions, we identify a rare population of gas-poor centrals in low-mass (M
h < 1011.4

) halos primarily located within ∼1.5× the virial radius of more massive (M
h > 1012

) halos, suggesting that gas stripping and/or starvation may be induced by interactions with larger halos or the surrounding cosmic web. We find that the detailed relationship between G/S and environment varies when we examine different subvolumes of RESOLVE independently, which we suggest may be a signature of assembly bias.

ABSTRACT
There is mounting evidence for the binary nature of the progenitors of gamma-ray bursts (GRBs). For a long GRB, the induced gravitational collapse paradigm proposes as progenitor, or “in-state,” a tight binary system composed of a carbon–oxygen core (CO

) undergoing a supernova explosion that triggers hypercritical accretion onto a neutron star (NS) companion. For a short GRB (S-GRB), an NS–NS merger is traditionally adopted as the progenitor. We divide long and S-GRBs into two subclasses, depending on whether or not a black hole (BH) is formed in the merger or in the hypercritical accretion process exceeding the NS critical mass. For long bursts, when no BH is formed, we have the subclass of X-ray flashes (XRFs), with isotropic energy

erg and rest-frame spectral peak energy

. When a BH is formed, we have the subclass of binary-driven hypernovae (BdHNe), with

erg and

. In analogy, short bursts are similarly divided into two subclasses. When no BH is formed, short gamma-ray flashes (S-GRFs) occur, with

erg and

. When a BH is formed, the authentic S-GRBs occur, with

erg and

. We give examples and observational signatures of these four subclasses and their rate of occurrence. From their respective rates it is possible that “in-states” of S-GRFs and S-GRBs originate from the “out-states” of XRFs. We indicate two additional progenitor systems: white dwarf–NS and BH–NS. These systems have hybrid features between long and short bursts. In the case of S-GRBs and BdHNe evidence is given of the coincidence of the onset of the high-energy GeV emission with the birth of a Kerr BH.
CONTACT BINARIES AS VIABLE DISTANCE INDICATORS: NEW, COMPETITIVE (V)JHKs PERIOD–LUMINOSITY RELATIONS
Authors: Chen Xiaodian , Grijs Richard de , Deng Licai 
Published: November 2016

ABSTRACT
Based on the largest catalogs currently available, comprising 6090 contact binaries (CBs) and 2167 open clusters (OCs), we determine the near-infrared (NIR) JHK
s CB period–luminosity (PL) relations, for the first time achieving the low levels of intrinsic scatter that make these relations viable as competitive distance calibrators. To firmly establish our distance calibration on the basis of OC CBs, we require that (i) the CB of interest must be located inside the core radius of its host cluster, (ii) the CB’s proper motion must be located within the 2σ distribution of that of its host OC, and (iii) the CB’s age, t, must be comparable to that of its host cluster, i.e.,

. We thus select a calibration sample of 66 CBs with either OC distances or accurate space-based parallaxes. The resulting NIR PL relations, for both late-type (i.e., W Ursae Majoris-type) and—for the first time—early-type CBs, are as accurate as the well-established JHK
s Cepheid PL relations, (characterized by single-band statistical uncertainties of σ < 0.10 mag). We show that CBs can be used as viable distance tracers, yielding distances with uncertainties of better than 5% for 90% of the 6090 CBs in our full sample. By combining the full JHK
s photometric data set, CBs can trace distances with an accuracy, σ = 0.05 (statistical) ± 0.03 (systematic) mag. The 102 CBs in the Large Magellanic Cloud are used to determine a distance modulus to the galaxy of

mag.
