description: Thanks to a grant of the Cultural Heritage Preservation Program of the German Ministry of Foreign Affairs the relief fragments and finds from the valley temple of the Bent Pyramid at Dahshur (about 2600 BC) in the magazines of Giza could be cleaned, restored, documented, catalogued and repacked in 2013. This work helps the Egyptian Antiquities Ministry to decide which objects shall be displayed in the „Grand Egyptian Museum“. The documentation of the relief fragments will result in a new attempt to reconstruct the decoration program of the valley temple, the oldest decorated pyramid temple of Egypt.

description: Excavations in November 2012 at the site of Watfa, ancient Philoteris in the north-western Fayum focussed on features along the ancient canals. Two areas of possible harbours were investigated. Drillings were carried out in the canals to understand their depth and width. Of special interest is a well which is connected by an underground tunnel to the larger water reservoirs in the north of the village. The well was situated on a piece of land of minor dimensions close to the village; it may have been used as an orchard or vineyard. Already in the pharaonic period, wells were typically part of vineyards because these required sophisticated irrigation systems.

description: The issue of the mechanism of high-Tc superconductivity remains open. In this contribution, we propose a new scenario for the mechanism of superconductivity in cuprates based on analysis of experimental data, mainly tunneling, neutron scattering and muon-spin-relaxation data, made earlier (see e.g. Mod. Phys. Lett. B 19 (2005) 743). A specific feature of this scenario is the mechanism of the establishment of long-range phase coherence among Cooper pairs, based on recent experimental data obtained in nonsuperconducting materials.

description: The survey covered 10 sites in the north-western Fayum; plans of the sites, most of which were inhabited from the 3rd century BC to the 4th AD, were drawn including all features still visible on the ground. Some of the sites have been massively divested of nearly all their buildings in the beginning of the 20th century, when the ancient building material of mud bricks was used as fertilizer on newly created fields. Today, land reclamation projects encroach on the sites drastically. The survey may be the last chance to record the already scanty remains which nevertheless, and together with the papyrological sources from the same sites, give a lively picture of those villages. The survey was concluded in 2013, and a monograph about the work will appear soon.
On the ergoregion instability in rotating gravastars

description: The ergoregion instability is known to affect very compact objects that rotate very rapidly and do not possess a horizon. We present here a detailed analysis on the relevance of the ergoregion instability for the viability of gravastars. Expanding on some recent results, we show that not all rotating gravastars are unstable. Rather, stable models can be constructed also with J/M^2 ~ 1, where J and M are the angular momentum and mass of the gravastar, respectively. The genesis of gravastars is still highly speculative and fundamentally unclear if not dubious. Yet, their existence cannot be ruled out by invoking the ergoregion instability. For the same reason, not all ultra-compact astrophysical objects rotating with J/M^2

description: The site of the ancient town on Elephantine island, close to present-day Assuan, offers the nearly unique chance to explore the structures and functions of an Ancient Egyptian provincial settlement from its village origins in late prehistory to its role as an important administrative and cultic center in pharaonic and graeco-roman times even into late antiquity and the early middle ages. Work in 2012 and 2013 was centered on two main project complexes. The reconstruction of the decoration, cultic installations, and uses of the temple of Khnum resulted in new insights into the building history and the symbolic layout of this largest sanctuary on the island. A fresh start in the excavation of settlement areas, harnessing the full potential of archaeometric methodology, aims at achieving a full picture the ancient living experience in the town of Elephantine.

description: Exact solutions with torsion in Einstein-Gauss-Bonnet gravity are derived. These solutions have a cross product structure of two constant curvature manifolds. The equations of motion give a relation for the coupling constants of the theory in order to have solutions with nontrivial torsion. This relation is not the Chern-Simons combination. One of the solutions has a $AdS_2\times S^3$ structure and is so the purely gravitational analogue of the Bertotti-Robinson space-time where the torsion can be seen as the dual of the covariantly constant electromagnetic field.

description: Deir el-Bakhit is a Coptic monastery, actually the ancient monastery of Paulos, situated on the hill of Dra‘ Abu el-Naga. The site offers a unique chance to follow Christian settlement in the ancient pharaonic necropolis from anachoretic beginnings in the later 5th century to monastic structures from the early 7th century until its end in the early 10th century. Research concentrates on the monastery building itself, its workshops and cemetery, no less, however on the system of ways and road posts and external installations which reveal a rich picture of the site which served as a way station at the beginning of the desert road to the oases. Important texts, ostraca and graffiti, were found which shed light on the people who lived in the monastery and on its functions.

Lately, the research focused on two areas: a free standing ancient settlement site, Kom el-Gir, about 4 km northeast of Buto, and fields about halfway between Buto and Kom el-Gir. At Kom el-Gir magnetic prospection revealed the plan of a settlement of the Ptolemaic and Roman periods. Auger core drillings in fields, marked as small ancient settlement sites on old maps, show no archaeological layers in this area.
Thiamine degradation in a luncheon-type ham product thermally processed in retort pouches and cans
Creators: name: Young, Kirsten Emily
Publisher: name: University of British Columbia
Year: 2010

description: Thiamine is an essential nutrient and meat products can serve as an important source of this vitamin. It is thermally labile and thus significant destruction can occur during the commercial sterilization of foods. This study investigated the thermal degradation kinetics of thiamine in a luncheon-type ham product. In addition, thiamine retention following processing of the product in retort pouches and metal cans at two retort temperatures was evaluated. Degradation of thiamine in the luncheon-type ham product was described by first order reaction kinetics for temperatures between 100 and 140°C, and temperature dependence of the reaction followed the Arrhenius equation. The activation energy was 105 kJ/mol and the reaction rate constant at a reference temperature of 121°C was 2.03x10⁻² min⁻¹. Thiamine retention was determined following processing of 397 g quantities of the luncheon-type ham product in 300x407 cans and 159 mm by 229 mm retort pouches restrained to 19 mm thickness. Retort temperatures of 115.6°C (240°F) and 126.7°C (260°F) were used to obtain minimum process lethalities of 6.0 min. As well, for a control, 184 g of product was processed at 115.6°C in the 307x111.5 cans used commercially. All cans were sterilized in pure steam whereas a 75/25 steam/ air mixture was used for the retort pouch processes. Analysis of variance indicated significant differences in thiamine retention among the package and processing temperature combinations (p ≤ 0.001). Student-Newman-Keuls multiple comparisons procedure showed that all treatments were significantly different from one another (p ≤ 0.05). The luncheon-type ham product processed in retort pouches required process times 61 and 75% shorter than processes of equivalent center-point lethality for cans at 115.6 and 126.7°C. As a consequence, the products in retort pouches retained 16 and 26% more thiamine than their canned counterparts at the two retort temperatures. The higher retort temperature for cans resulted in a k% decrease in thiamine retention compared to the lower temperature, while for retort pouches there was a 6% increase in thiamine retained. The product processed in the smaller control cans at 115.6°C had a level of thiamine retention intermediate between that processed in retort pouches and the larger cans.

description: A recent observation has shown that PSR B1257+12 could have quite small X-ray emitting area, only about 2000 m$^2$, which is more than three orders smaller than the canonical polar cap size. We suggest here that PSR B1257+12 could be a low-mass quark star with radius of $R \simeq 0.6$ km and mass of $M \simeq 3\times10^{-4}\msun$. Such a low-mass quark star system may form in an accretion induced collapse process or a collision process of two quark stars.

description: We present \textit{ALMA} 1.3 mm and 0.86 mm observations of the nearby (17.34 pc) F9V star q1 Eri (HD 10647, HR 506). This system, with age ${\sim}1.4$ Gyr, hosts a ${\sim}2$ au radial velocity planet and a debris disc with the highest fractional luminosity of the closest 300 FGK type stars. The \textit{ALMA} images, with resolution ${\sim}0.5''$, reveal a broad (34{-}134 au) belt of millimeter emission inclined by $76.7{\pm}1.0$ degrees with maximum brightness at $81.6{\pm}0.5$ au. The images reveal an asymmetry, with higher flux near the southwest ansa, which is also closer to the star. Scattered light observed with the Hubble Space Telescope is also asymmetric, being more radially extended to the northeast. We fit the millimeter emission with parametric models and place constraints on the disc morphology, radius, width, dust mass, and scale height. We find the southwest ansa asymmetry is best fitted by an extended clump on the inner edge of the disc, consistent with perturbations from a planet with mass $8 M_{\oplus} {-} 11 M_{\rm Jup}$ at ${\sim}60$ au that may have migrated outwards, similar to Neptune in our Solar System. If the measured vertical aspect ratio of $h{=}0.04{\pm}0.01$ is due to dynamical interactions in the disc, then this requires perturbers with sizes ${>}1200$ km. We find tentative evidence for an 0.86 mm excess within 10 au, $70{\pm}22\, μ$Jy, that may be due to an inner planetesimal belt. We find no evidence for CO gas, but set an upper bound on the CO gas mass of $4{\times}10^{-6}$ M$_{\oplus}$ ($3\,σ$), consistent with cometary abundances in the Solar System.

description: Lipocalins are one of the groups of allergens derived from animals with greater clinical importance for the development of respiratory allergies in humans. To identify possible antigenic regions involved in cross-reactivity, it is explored through bioinformatics tools through the MEGA, Swiss Modeller and PYMOL bioinformatic tools. Five clades resulted from the alignment and allergens Fel d 4, Rat n 1 and Equ c 1 presented the highest identity (58%). This explains the cross-reactivity between allergens of intraspecies domestic animals and the need to create directed mutagenesis for diagnosis and treatment.

For equal numbers of zealots of each species, the distribution of magnetization (opinions) is Gaussian in the mean-field limit as well as in one and two dimensions, with a width that is proportional to 1/sqrt{Z}, where Z is the number of zealots, independent of the total number of voters. Thus just a few zealots can prevent consensus or even the formation of a robust majority.

description: lenstronomy is an Astropy-affiliated Python package for gravitational lensing simulations and analyses. lenstronomy was introduced by Birrer and Amara (2018) and is based on the linear basis set approach by Birrer et a. (2015). The user and developer base of lenstronomy has substantially grown since then, and the software has become an integral part of a wide range of recent analyses, such as measuring the Hubble constant with time-delay strong lensing or constraining the nature of dark matter from resolved and unresolved small scale lensing distortion statistics. The modular design has allowed the community to incorporate innovative new methods, as well as to develop enhanced software and wrappers with more specific aims on top of the lenstronomy API. Through community engagement and involvement, lenstronomy has become a foundation of an ecosystem of affiliated packages extending the original scope of the software and proving its robustness and applicability at the forefront of the strong gravitational lensing community in an open source and reproducible manner.

A unified approach to the geometric rectification of remotely sensed imagery
Creators: name: Wong, Frank Hay-Chee
Publisher: name: University of British Columbia
Year: 2010

description: Many applications of remotely sensed digital imagery require images that are corrected for geometric distortions. It is often desirable to rectify different types of satellite imagery to a common data base. A high throughput rectification system is required for commercial application. High geometric and radiometric precision must be maintained. The thesis has accomplished the following tasks: 1. The sensors used to obtain remotely sensed imagery have been investigated and the associated geometric distortions inherent with each sensor are identified. 2. The transformation between image coordinates and datum coordinates has been determined and the values of the parameters in the transformation are estimated. 3. A unified rectification approach has been developed, for all types of remotely sensed digital imagery, which yields a high system throughput. 4. Use of digital terrain models in the rectification process to correct for relief displacement has been incorporated. 5. An efficient image interpolation algorithm has been developed. This algorithm takes into account the fact that imagery does not always correspond to sampling on a uniform grid. 6. The applications of rectified imagery such as mosaicking and multisensor integration have been studied. 7. Extension of the rectification algorithm to a future planetary mission has been investigated. The sensors studied include TIROS-N, Landsat-1, -2 and -3 multispectral scanners, Seasat synthetic aperture radar, Landsat-4 thematic mapper and SPOT linear array detectors. Imagery from the last two sensors is simulated.

description: We present a theoretical study of the linear response of a driven-dissipative hybrid optomechanical system consisting of an interacting one-dimensional Bose-Einstein condensate (BEC) to an external time-dependent perturbation in the framework of the generalized linear response theory. Using the equations of motion of the open quantum system Green's function, we obtain the linear responses of the optical and atomic modes of the hybrid system and show how the atom-atom interaction of the BEC atoms affects the two normal resonances of the system as well as the anti-resonance frequency at which the optical field amplitude of the cavity becomes zero. Furthermore, an interpretation of the anti-resonance phenomenon is presented based on the the optical spectral density and the self-energy.

description: The tell of Göbekli Tepe is situated a few kilometres to the northeast of Şanlıurfa in south-eastern Turkey. The immense ruin hill formed by the debris of monumental constructions dating back to the 10th and 9th millennium BC (the Pre-Pottery Neolithic) has been excavated systematically since 1995. Recent excavation campaigns focussed on preliminary work for the erection of permanent shelter structures to preserve the site.

description: The “Syrian Heritage Archive Project“ deals with the digitization of analogue research data from Syria. It captures research projects and scholarly archives of the DAI and the Museum of Islamic Art, seeks to prepare the information in a structured manner and to make it available through the various electronic data processing systems of iDAI.world (iDAI.objects, iDAI.gazetteer, iDAI. geoserver, iDAI.bibliography). Against the backdrop of the ongoing civil war, the target application is to provide a large-scale dataset for a register of archaeological sites and historical monuments of Syria.

description: We report a theoretical study of Feshbach resonances in $^{6}$Li + $^{23}$Na and $^{7}$Li + $^{23}$Na mixtures at ultracold temperatures using new accurate interaction potentials in a full quantum coupled-channel calculation. Feshbach resonances for $l=0$ in the initial collisional open channel $^6$Li$(f=1/2, m_f=1/2) + ^{23}$Na$(f=1, m_f=1)$ are found to agree with previous measurements, leading to precise values of the singlet and triplet scattering lengths for the $^{6,7}$Li$+^{23}$Na pairs. We also predict additional Feshbach resonances within experimentally attainable magnetic fields for other collision channels.

description: Binary population synthesis (BPS) employs prescriptions to predict final fates, explosion or implosion, and remnant masses based on one or two stellar parameters at the evolutionary cutoff imposed by the code, usually at or near central carbon ignition. In doing this, BPS disregards the integral role late-stage evolution plays in determining the final fate, remnant type, and remnant mass within the neutrino-driven explosion paradigm. To highlight differences between a popular prescription which relies only on the core and final stellar mass and emerging methods which rely on a star's presupernova core structure, we generate a series of compact object distributions using three different methods for a sample population of single and binary stars computed in BPASS. The first method estimates remnant mass based on a star's carbon-oxygen (CO) core mass and final total mass. The second method uses the presupernova core structure based on the bare CO-core models of \citet{Pat20} combined with a parameterized explosion criterion to first determine final fate and remnant type, then remnant mass. The third method associates presupernova helium-core masses with remnant masses determined from public explosion models which rely implicitly on core structure. We find that the core-/final mass-based prescription favors lower mass remnants, including a large population of mass gap black holes, and predicts neutron star masses which span a wide range, whereas the structure-based prescriptions favor slightly higher mass remnants, mass gap black holes only as low as 3.5 \Msun, and predict neutron star mass distributions which cluster in a narrow range.

description: The Late Neolithic site of Shir near Hama was extensively excavated between 2005 and 2010. Central issues within the research program were aspects of the development of the settlement and the relationship between the settlement and the surrounding area. The analysis of the excavation data currently being conducted provides a picture of a complex society in one of the core regions for the Neolithization process in the Near East. The results will allow a better understanding of settlement activities during the 7th millennium BCE in the Northern Levant.

description: Volume conductor problems in cerebral electrophysiology and bioimpedance do not have analytical solutions for nontrivial geometries and require a 3D model of the head and its electrical properties for solving the associated PDEs numerically. Ideally, the model should be made with patient-specific information. In clinical practice, this is not always the case and an average head model is often used. Also, the electrical properties of the tissues might not be completely known due to natural variability. The objective of this work is to develop a 4D (3D+T) statistical anatomical atlas of the electrical properties of the upper part of the human head for cerebral electrophysiology and bioimpedance applications. The atlas is an important tool for in silico studies on cerebral circulation and electrophysiology that require statistically consistent data, e.g., machine learning, sensitivity analyses, and as a benchmark to test inverse problem solvers. The atlas was constructed based on MRI images of human individuals and comprises the electrical properties of the main internal structures and can be adjusted for specific electrical frequencies. The proposed atlas also comprises a time-varying model of arterial brain circulation, based on the solution of the Navier-Stokes equation in the main arteries and their vascular territories. The atlas was successfully used to simulate electrical impedance tomography measurements indicating the necessity of signal-to-noise between 100 and 125dB to identify vascular changes due to the cardiac cycle, corroborating previous studies.

description: The urban town of Hamadab flourished during the Meroitic period (3rd century BC to 4th century AD) 3 km south of the ancient capital Meroe on the east bank of the Nile. It is subject of a German-Sudanese research project since 2001. The report summarises our recent fieldwork at Hamadab in 2013 and 2014, which focused on excavations in the settlement’s Upper Town and on a new study of the historic land use in relation to the environment of the Meroe-Hamadab region.
Poromechanical behaviour of hardened cement paste under isotropic loading

description: The poromechanical behaviour of hardened cement paste under isotropic loading is studied on the basis of an experimental testing program of drained, undrained and unjacketed compression tests. The macroscopic behaviour of the material is described in the framework of the mechanics of porous media. The poroelastic parameters of the material are determined and the effect of stress and pore pressure on them is evaluated. Appropriate effective stress laws which control the evolution of total volume, pore volume, solid volume, porosity and drained bulk modulus are discussed. A phenomenon of degradation of elastic properties is observed in the test results. The microscopic observations showed that this degradation is caused by the microcracking of the material under isotropic loading. The good compatibility and the consistency of the obtained poromechanical parameters demonstrate that the behaviour of the hardened cement paste can be indeed described within the framework of the theory of porous media.

description: Questo concorso, dall’oggetto assolutamente affascinante di un ponte (solo fisico o anche ideale?) sull’invaso del Pertusillo, ha prodotto grande eco ed anche effetti indotti di aumento della conoscenza della nostra regione, ma ha prodotto anche circa 80 magnifiche idee per una grande struttura, con una partecipazione, peraltro, molto diversificata di professionisti, dai giovanissimi fino ai rappresentanti degli studi più famosi, alimentando così un rinnovato entusiasmo nella competizione. Non v’è dubbio alcuno che solo attraverso queste modalità si può raggiungere il livello qualitativo adeguato, nello specifico dei progetti, ma più in generale nell’atteggiamento mentale di ciascuno, presupposto indispensabile di un futuro migliore.

description: E’ un obbligo della società civile aver cura dei beni culturali, provvedere alla loro salvaguardia, rispettandone le caratteristiche attraverso una manutenzione costante che esclude la necessità di interventi radicali da attuare in regime di urgenza, come purtroppo troppo spesso accade. Il restauro è un atto di riflessione complessa e, in quanto tale, non può essere alla portata di molti, richiede competenza ed esperienza, ma soprattutto sensibilità. Solo chi ama la materia e ne conosce l’essenza è in grado di offrire le necessarie garanzie per un corretto approccio al problema, anche se spesso ciò non costituisce condizione sufficiente per conseguire risultati accettabili sotto il profilo della tutela stessa, della valorizzazione e soprattutto della fruizione del bene sul quale si interviene.

description: Negli ultimi cinquant’anni il paesaggio più tradizionale della Basilicata è stato fortemente modificato proprio dalla realizzazione di importanti infrastrutture per la mobilità, oltre che dalla realizzazione degli invasi artificiali. Infrastrutture viarie ed invasi artificiali sono peraltro gli elementi che caratterizzano il territorio ed il paesaggio di Spinoso e della Val d’Agri più in generale. Un tale progetto di infrastrutturazione del territorio regionale, peraltro ad oggi non del tutto completato, nasce da lontano; in particolare da quelli che sono stati i principali atti di pianificazioni territoriale e di programmazione economica della regione, a partire dalla metà degli anni ’60 del secolo scorso.

description: We consider two-loop QCD corrections to the element $Γ_{12}^q$ of the decay matrix in $B_q-\bar{B}_q$ mixing, $q=d,s$, in the leading power of the Heavy Quark Expansion. The calculated contributions involve one current-current and one penguin operator and constitute the next step towards a theory prediction for the width difference $ΔΓ_s$ matching the precise experimental data. We present compact analytic results for all matching coefficients in an expansion in $m_c/m_b$ up to second order. Our new corrections are comparable in size to the current experimental error and slightly increase $ΔΓ_s$.
