description: We present the results of a survey for super Lyman limit systems (SLLS; defined to be absorbers with 19.0 <= log(NHI) <= 20.3 cm^-2) from a large sample of high resolution spectra acquired using the Keck and Magellan telescopes. Specifically, we present 47 new SLLS from 113 QSO sightlines. We focus on the neutral hydrogen frequency distribution f(N,X) of the SLLS and its moments, and compare these results with the Lyman-alpha forest and the damped Lyman alpha systems (DLA; absorbers with log(NHI) >= 20.3 cm^-2). We find that that f(N,X) of the SLLS can be reasonably described with a power-law of index alpha = -1.43^{+0.15}_{-0.16} or alpha = -1.19^{+0.20}_{-0.21} depending on whether we set the lower N(HI) bound for the analysis at 10^{19.0} cm^-2 or 10^{19.3}$ cm^-2, respectively. The results indicate a flattening in the slope of f(N,X) between the SLLS and DLA. We find little evidence for redshift evolution in the shape of f(N,X) for the SLLS over the redshift range of the sample 1.68 < z < 4.47 and only tentative evidence for evolution in the zeroth moment of f(N,X), the line density l_lls(X). We introduce the observable distribution function O(N,X) and its moment, which elucidates comparisons of HI absorbers from the Lyman-alpha through to the DLA. We find that a simple three parameter function can fit O(N,X) over the range 17.0 <= log(NHI) <=22.0. We use these results to predict that f(N,X) must show two additional inflections below the SLLS regime to match the observed f(N,X) distribution of the Lyman-alpha forest. Finally, we demonstrate that SLLS contribute a minor fraction (~15%) of the universe's hydrogen atoms and, therefore, an even small fraction of the mass in predominantly neutral gas.

description: The immune system plays a very important role in controlling the growth of neoplasms as is evident by the fact that people with immune defects have a higher frequency of tumors. The purpose of this project was to perform a preliminary comparison of the response of T lymphocytes from cancer patients with that of lymphocytes from normal individuals after stimulation with anti-CD3. Peripheral blood T cells from eight melanoma patients and a control group of five normal individuals were evaluated for the ability to transduce a signal through the T cell receptor (TCR)/CD3 complex. The level of transduction was determined by measuring the increase in intracellular calcium ([Ca²⁺]₁) levels following activation with the monoclonal antibody anti-CD3 (OKT3). The concentration of free intracellular Ca²⁺ of unstimulated T cells from the patient samples was approximately 100 nM, similar to that of the normal individuals. Mean increases in [Ca²⁺]₁ after anti-CD3 stimulation in the melanoma patients were comparable to those of the normal controls. One patient had a value significantly lower than the normal range and one had a value significantly higher than both the other patients and the control group. In this limited study using unfractionated T cells and optimized stimulation conditions, no population differences were observed between the two subject groups. The surface expression of activation antigens on T lymphocytes from the patient and control groups before and after 24 hour anti-CD3 stimulation was also evaluated as an indication of T cell responsiveness. CD3 expression was downregulated on both CD4 and CD8 xii lymphocytes from normal donors and melanoma patients after stimulation with anti-CD3. The percentage of CD4+ and CD4- lymphocytes from both groups that coexpress CD25 increased after stimulation with anti-CD3, as did CD4+ and CD4- cells from both groups that coexpress CD69. After stimulation with anti-CD3 the percentage of CD4+ and CD4- cells that coexpress CD38 and HLADR did not significantly increase in either subject group. Variability in expression of all the activation markers existed between individuals, but no significant population differences were seen between the two subject groups. This prelimary study failed to distinguish differences in the response of T cells from melanoma patients and normal donors to anti-CD3 stimulation. The study was limited in scope, and the number of subjects in both study groups was restricted. No conclusions can be drawn from these studies regarding T cell defects in melanoma patients.

description: The thermal management of an outdoor electronic enclosure can be quite challenging due to the additional thermal load from the sun and the requirement of having an air-sealed enclosure. It is essential to consider the effect of solar heating loads in the design process; otherwise, it can shorten the life expectancy of the electronic product or lead to catastrophic failure. In this paper we analyze and compare the effectiveness of different cooling techniques used for outdoor electronics. Various cooling techniques were compared like special coatings and paints on the outer surface, radiation shields, double-walled vented enclosures, fans for internal air circulation and air-to-air heat exchangers. A highly simplified, typical outdoor system was selected for this study measuring approximately 300x300x400 mm (WxLxH). Solar radiation was incident on 3 sides of the enclosure. There were 8 equally spaced PCBs inside the enclosure dissipating 12.5W each uniformly (100 watts total). A computational fluid dynamics (CFD) model of the system was built and analyzed. This was followed by building a mock-up of the system and conducting experiments to validate the CFD model. It was found that some of the simplest cooling techniques like white oil paint on the outer surface can significantly reduce the impact of solar loads. Adding internal circulation fans can also be very effective. Using air-to-air heat exchangers was found to be the most effective solution although it is more complex and costly.

description: We investigate the impact of noise and topology on opinion diversity in social networks. We do so by extending well-established models of opinion dynamics to a stochastic setting where agents are subject both to assimilative forces by their local social interactions, as well as to idiosyncratic factors preventing their population from reaching consensus. We model the latter to account for both scenarios where noise is entirely exogenous to peer influence and cases where it is instead endogenous, arising from the agents' desire to maintain some uniqueness in their opinions. We derive a general analytical expression for opinion diversity, which holds for any network and depends on the network's topology through its spectral properties alone. Using this expression, we find that opinion diversity decreases as communities and clusters are broken down. We test our predictions against data describing empirical influence networks between major news outlets and find that incorporating our measure in linear models for the sentiment expressed by such sources on a variety of topics yields a notable improvement in terms of explanatory power.

description: We study various aspects of four dimensional Einstein-Maxwell multicentred gravitational instantons. These are half-BPS Riemannian backgrounds of minimal N=2 supergravity, asymptotic to R^4, R^3 x S^1 or AdS_2 x S^2. Unlike for the Gibbons-Hawking solutions, the topology is not restricted by boundary conditions. We discuss the classical metric on the instanton moduli space. One class of these solutions may be lifted to causal and regular multi `solitonic strings', without horizons, of 4+1 dimensional N=2 supergravity, carrying null momentum.

description: In the high spin-orbit coupled Sr2IrO4, the high sensitivity of the ground state to the details of the local lattice structure shows a large potential for the manipulation of the functional properties by inducing local lattice distortions. We use epitaxial strain to modify the Ir-O bond geometry in Sr2IrO4 and perform momentum-dependent Resonant Inelastic X-ray Scattering (RIXS) at the metal and at the ligand sites to unveil the response of the low energy elementary excitations. We observe that the pseudospin-wave dispersion for tensile-strained Sr2IrO4 films displays large softening along the [h,0] direction, while along the [h,h] direction it shows hardening. This evolution reveals a renormalization of the magnetic interactions caused by a strain-driven crossover from anisotropic to isotropic interactions between the magnetic moments. Moreover, we detect dispersive electron-hole pair excitations which shift to lower (higher) energies upon compressive (tensile) strain, manifesting a reduction (increase) in the size of the charge gap. This behavior shows an intimate coupling between charge excitations and lattice distortions in Sr2IrO4, originating from the modified hopping elements between the t2g orbitals. Our work highlights the central role played by the lattice degrees of freedom in determining both the pseudospin and charge excitations of Sr2IrO4 and provides valuable information towards the control of the ground state of complex oxides in the presence of high spin-orbit coupling.

description: An acoustic field is used to increase the critical heat flux (CHF) of a flat-boiling-heat-transfer surface. The increase is a result of the acoustic effects on the vapor bubbles. Experiments are performed to explore the effects of an acoustic field on vapor bubbles in the vicinity of a rigid-heated wall. Work includes the construction of a novel heater used to produce a single vapor bubble of a prescribed size and at a prescribed location on a flatboiling surface for better study of an individual vapor bubble's reaction to the acoustic field. Work also includes application of the results from the single-bubble heater to a calibrated-copper heater used for quantifying the improvements in CHF.

Σκοπός της παρούσας έρευνας ήταν η διερεύνηση της επίδρασης ενός μουσικοκινητικού προγράμματος στην ανάπτυξη των κινητικών δεξιοτήτων (αδρής και λεπτής) και της πρακτικής αντίληψης σε παιδιά προσχολικής ηλικίας. Στην παρούσα έρευνα συμμετείχαν 70 παιδιά προσχολικής ηλικίας. Για την εκτίμηση της κινητικής ανάπτυξης χρησιμοποιήθηκαν οι δυο κινητικές κλίμακες (Α, Δ) αδρής και λεπτής καθώς και της πρακτικής αντίληψης (ΣΤ) της δοκιμασίας της Griffiths No ΙΙ. Για την ανάλυση των αποτελεσμάτων χρησιμοποιήθηκε η ανάλυση διακύμανσης δυο παραγόντων με επαναλαμβανόμενες μετρήσεις (two way Anova – repeated measures). Από τα αποτελέσματα φάνηκε ότι η πειραματική ομάδα παρουσίασε μεγαλύτερη βελτίωση και στις τρεις κλίμακες που εξετάστηκαν (p< .05) σε σύγκριση με την ομάδα ελέγχου. Από την έρευνα συμπεραίνεται ότι μέσα από ένα καθοδηγούμενο πρόγραμμα άσκησης με στοιχεία μουσικοκινητικής και ποικιλία κινητικών δραστηριοτήτων μπορεί να επιτευχθεί η ταχύτερη ανάπτυξη σε βασικούς τομείς της ανάπτυξης των παιδιών προσχολικής ηλικίας.
description: Psychomotor education is a complete method of motor education and is more widely accepted and applied in the educational system, as it approaches the child as a whole and aims at promoting mental, psychic and motor aspects of children at the same time. The purpose of this research was to examine the impact of a music and movement program in the development of motor skills (gross and fine) and the practical reasoning scale on preschoolers. Seventy (70) preschool aged children participated in this study. For the evaluation of motor development both motor subscales (A, D) gross and fine were used, along with the practical reasoning scale of the Griffiths test No II. For analyzing the results the method of analysis Two way Anova-repeated measures was used. It became clear from the results that the experimental group showed greater improvement than the control group. As a result of the research, we can conclude that through a specifically and guided program with music and movement elements and a variety of motor activities, we can achieve faster development in main areas of preschool children development.

description: An innovative and accurate dynamic Compact Thermal Model extraction method is proposed for multi-chip power electronics systems. It accounts for thermal coupling between multiple heat sources. Transient electro-thermal coupling can easily be taken into account by system designers. The method is based on a definition of the Optimal Thermal Coupling Point, which is proven to be valid even for transient modelling. Compared to the existing methods, the number of needed 3D thermal simulations or measurements is significantly reduced.

Limit point buckling of a finite beam on a nonlinear foundation

Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: In this paper, we consider an imperfect finite beam lying on a nonlinear foundation, whose dimensionless stiffness is reduced from $1$ to $k$ as the beam deflection increases. Periodic equilibrium solutions are found analytically and are in good agreement with a numerical resolution, suggesting that localized buckling does not appear for a finite beam. The equilibrium paths may exhibit a limit point whose existence is related to the imperfection size and the stiffness parameter $k$ through an explicit condition. The limit point decreases with the imperfection size while it increases with the stiffness parameter. We show that the decay/growth rate is sensitive to the restoring force model. The analytical results on the limit load may be of particular interest for engineers in structural mechanics

description: A light-weight "inflatable" tensioned-membrane-structure vacuum container is proposed and its stability is analyzed. The proposed structure consists of a pressurized lobed cylindrical "wall" surrounding a central evacuated space. Stability is analyzed by discretizing the system and diagonalizing the second derivative of the potential energy. The structure is found to be stable when the pressure in the wall is greater than a critical pressure. When membranes are non-elastic, the critical pressure is found to be greater than the pressure required for equilibrium by a factor of 4/3. When membranes have only finite stiffness, a first order correction to the critical pressure is found. Preliminary experimental data shows that a stable structure can be made in this way, and that the observed critical pressure is consistent with theory. It is also found that such structures can be designed to have net positive buoyancy in air.

H εργασία αναπτύσσεται σε 4 κύριες ενότητες. H πρώτη ενότητα, με τίτλο «Ιερά και λατρεία του Διός στις πόλεις της Καρίας», περιλαμβάνει μία λεπτομερή παρουσίαση όλων των ιερών του θεού, που βρίσκονται στην Καρία. Πρόκειται για ιερά ανεσκαμμένα αλλά και για ιερά τα οποία είναι γνωστά από επιγραφές και αρχαίους συγγραφείς. Στη δεύτερη ενότητα, με τίτλο «Η παρουσία του Διός και των συμβόλων του στις νομισματικές κοπές των Εκατομνιδών» εξετάζονται τα νομίσματα των Εκατομνιδών, στα οποία εμφανίζεται ο Ζευς και το χαρακτηριστικό του σύμβολο για την περιοχή αυτή, ο διπλός πέλεκυς (λάβρυς). Στο τρίτο κεφάλαιο, με τίτλο «τα επίθετα του Διός στην Καρία», παρουσιάζονται όλα τα επίθετα, με τα οποία ο Ζευς λατρευόταν στην Καρία. Στο τελευταίο μέρος του κυρίως μέρους της εργασίας συγκεντρώνονται τα συμπεράσματα, τα οποία προκύπτουν από την εξέταση όλων των παραπάνω. Τα συμπεράσματα αυτά αφορούν την παρουσία του Διός στο χώρο που μελετήθηκε, καθώς και θέματα σχετικά με τα ιερά του αλλά και με την εικονογραφία του μεγαλύτερου θεού των Ελλήνων.
description: This paper deals with the sanctuaries and the cult of god Zeus in Caria of Asia Minor during the antiquity. The presence of god Zeus in this geographical space is important and dates from the archaic age and this is apparent both in literary sources and the archaeological evidence from that period. From all the sanctuaries of Zeus in Caria, we could say that the most organized and dominant of them, were the sanctuaries, dedicated in the local cults of the god. The study unfolds in 4 major chapters. The first chapter, titled “Sanctuaries and cult of Zeus in the carian towns” includes a detailed presentation of all the sanctuaries of Zeus located in Caria. There are excavated sanctuaries and sanctuaries known from inscriptions or ancient authors as well. The second chapter, titled “The presence of Zeus and his symbols at Hecatomnid coinage”, examines the coins of Hecatomnids, in which Zeus and his major symbol in Caria, the double axe (labrys), appear. All the cult names of Zeus, which are known from the area of Caria are presented at the third chapter, titled “Names of Zeus in Caria”. In the last chapter of the main part of the study are assembled the conclusions of the research, based on what was discussed above.

description: Albertosaurus
 and Gorgosaurus— Albertosaurus libratus is based on a nearly complete skeleton (NMC 2120) described by Lambe (1914a, b, 1917) as Gorgosaurus libratus. The holotype skull is crushed, but most of it is preserved. It hails from the Dinosaur Park Formation and is the best-sampled North American tyrannosaurid, with multiple well-preserved specimens having been collected since Lambe’s time.
 Albertosaurus sarcophagus Osborn, 1905 is based on a partial skeleton (NMC 5600) from the overlying Edmonton Formation of Alberta (Osborn, 1905). It is not as well preserved as the type of A. libratus. A partial skeleton with no skull from the Edmonton was later described by Parks (1928) as Albertosaurus arctunguis', most authorities now regard A. arctunguis to be a junior synonym of A. sarcophagus (Molnar et al., 1990; Carpenter, 1992).
 Russell (1970) was the first to synonymize Gorgosaurus with Albertosaurus. I agree with Holtz (2001a) that the character states diagnosing a more inclusive Albertosaurus are plesiomorphic (and thus problematic), and the characters used by Russell (1970) to separate them as species rely on skull and limb proportions that might be subject to preservational or ontogenetic variation. Ongoing work by Philip Currie (P. Currie, pers. comm.) is clarifying the diagnoses of these fossils, but for purposes of this analysis, they will be considered species of Albertosaurus.
 Carpenter (1992) argued that the promaxillary fenestra lies close to the maxillary fenestra in A. libratus, but not in A. sarcophagus, and that the promaxillary fenestra of A. libratus is invisible in lateral view. In all mature A. libratus and A. sarcophagus maxillae available for this study, the morphology of the maxillary and promaxillary fenestrae was identical. The reconstruction of A. libratus figured by Carpenter (1992:fig. 2E) looks similar to that published by Russell (1970:fig. 1), but in Russell’s reconstruction, the lateral morphological details are based on FMNH PR308. In that specimen, the promaxillary fenestra is not preserved on either side. In fact, based on the number of dentary and maxillary alveoli, this specimen may pertain to Daspletosaurus, not Albertosaurus (Carr, 1999; Holtz, 2001a)—and the promaxillary fenestra is not visible in lateral view in Daspletosaurus, as implied by Carpenter (1992) for A. libratus.

description: We present the first spectroscopically resolved \ha\ emission map of the Large Magellanic Cloud's (LMC) galactic wind. By combining new Wisconsin H-alpha Mapper (WHAM) observations ($I_{\rm Hα}\gtrsim10~{\rm mR}$) with existing \hicm\ emission observations, we have (1) mapped the LMC's near-side galactic wind over a local standard of rest (LSR) velocity range of $+50\le\rm v_{LSR}\le+250~{\rm km}~{\rm s}^{-1}$, (2) determined its morphology and extent, and (3) estimated its mass, outflow rate, and mass-loading factor. We observe \ha\ emission from this wind to typically 1-degree off the LMC's \hi\ disk. Kinematically, we find that the diffuse gas in the warm-ionized phase of this wind persists at both low ($\lesssim100~{\rm km}~{\rm s}^{-1}$) and high ($\gtrsim100~{\rm km}~{\rm s}^{-1}$) velocities, relative to the LMC's \hi\ disk. Furthermore, we find that the high-velocity component spatially aligns with the most intense star-forming region, 30~Doradus. We, therefore, conclude that this high-velocity material traces an active outflow. We estimate the mass of the warm ($T_e\approx10^4~\rm K$) ionized phase of the near-side LMC outflow to be $\log{\left(M_{\rm ionized}/M_\odot\right)=7.51\pm0.15}$ for the combined low and high velocity components. Assuming an ionization fraction of 75\% and that the wind is symmetrical about the LMC disk, we estimate that its total (neutral and ionized) mass is $\log{\left(M_{\rm total}/M_\odot\right)=7.93}$, its mass-flow rate is $\dot{M}_{\rm outflow}\approx1.43~M_\odot~\rm yr^{-1}$, and its mass-loading factor is $η\approx4.54$. Our average mass-loading factor results are roughly a factor of 2.5 larger than previous \ha\ imaging and UV~absorption line studies, suggesting that those studies are missing nearly half the gas in the outflows.

description: Echocardiography (echo) is an indispensable tool in a cardiologist's diagnostic armamentarium. To date, almost all echocardiographic parameters require time-consuming manual labeling and measurements by an experienced echocardiographer and exhibit significant variability, owing to the noisy and artifact-laden nature of echo images. For example, mitral inflow (MI) Doppler is used to assess left ventricular (LV) diastolic function, which is of paramount clinical importance to distinguish between different cardiac diseases. In the current work we present a fully automated workflow which leverages deep learning to a) label MI Doppler images acquired in an echo study, b) detect the envelope of MI Doppler signal, c) extract early and late filing (E and A wave) flow velocities and E-wave deceleration time from the envelope. We trained a variety of convolutional neural networks (CNN) models on 5544 images of 140 patients for predicting 24 image classes including MI Doppler images and obtained overall accuracy of 0.97 on 1737 images of 40 patients. Automated E and A wave velocity showed excellent correlation (Pearson R 0.99 and 0.98 respectively) and Bland Altman agreement (mean difference 0.06 and 0.05 m/s respectively and SD 0.03 for both) with the operator measurements. Deceleration time also showed good but lower correlation (Pearson R 0.82) and Bland-Altman agreement (mean difference: 34.1ms, SD: 30.9ms). These results demonstrate feasibility of Doppler echocardiography measurement automation and the promise of a fully automated echocardiography measurement package.
Self-Learning Hard Disk Power Management for Mobile Devices

description: A multitude of different hard disk power management algorithms exists-applied to real systems or proposed in the literature. Energy savings can only be achieved if the hard disk is idle for a minimum period of time. These algorithms try to predict the length of each idle interval at runtime and decide whether the disk should be switched to a low-power mode or not. In this paper, we claim that there is no general-purpose policy that maximizes energy savings for every workload and present system services that dynamically switch between different, specialized power management algorithms. The operating system automatically learns which policy performs best for a specific workload. Therefore, hard disk accesses are monitored and fed into a simulator that estimates the drive's energy consumption under different low-power algorithms. In order to recognize workloads at runtime, the system additionally monitors a set of I/O-related parameters. Using techniques from machine learning, a set of rules can be derived automatically which enable a power management daemon to identify the current workload and its optimum low-power algorithm on-line. Furthermore, the user can train the system to consider application-specific performance requirements. A prototype implementation for Linux is presented and evaluated through experiments with two different hard disks.

description: Since the discovery of chemically peculiar stars in globular clusters in the last century, the study of multiple populations has become increasingly important, given that chemical inhomogeneity is found in almost all globular clusters. Despite various proposed theories attempting to explain this phenomenon, fitting all the observational evidence in globular clusters with one single theory remains notoriously difficult and currently unsuccessful. In order to improve existing models and motivate new ones, we are observing globular clusters at critical conditions, e.g., metal-rich end, metal-poor end, and low mass end. In this paper, we present our first attempt to investigate multiple populations in low mass globular clusters. We obtained low-resolution spectra around 4000 A of 30 members of the globular cluster Palomar 13 using OSIRIS/Multi-object spectrograph mounted at the Gran Telescopio Canarias. The membership of red giant branch stars is confirmed by the latest proper motions from Gaia DR2 and literature velocities. After comparing the measured CN and CH spectral indices with those of the stellar models, we found a clear sign of nitrogen variation among the red giant branch stars. Palomar 13 may be the lowest mass globular cluster showing multiple populations.

description: Daspletosaurus torosus Russell, 1970
 — Russell (1970) based Daspletosaurus torosus on a partial skull and skeleton, NMC 8506, from the Campanian Dinosaur Park Formation (Oldman Formation in Russell, 1970) of Alberta. It had a somewhat longer rostrum than other tyrannosaurids, and the number of maxillary or dentary alveoli at maturity may exceed 15.
 Material from the Early Maastrichtian Two Medicine Formation, including an undescribed skeleton (MOR 590), is very similar to Daspletosaurus (Horner et al., 1992; Holtz, 2001a) and may pertain to it (Varricchio, 2001). Daspletosaurus has also been reported from the Early Maastrichtian Horseshoe Canyon Formation of Alberta (Ryan and Russell, 2001).
 The Dinosaur Park, Oldman, and Horseshoe Canyon Formations appear to be the only units in which two large tyrannosaurids (Albertosaurus / Gorgosaurus and Daspletosaurus) cooccur. This complicates our attempts to compare any tyrannosaurid skeleton with isolated fossils from either formation, as such bones could pertain to either taxon. There are several cranial characters that clearly separate the two, including number of teeth, size and orientation of the jugal foramen, and morphology of the promaxillary foramen, but incomplete (essentially postcranial) material may not be diagnosable to either taxon, and some may only be distinctive in mature individuals. An immature tyrannosaurid skull and skeleton from the Dinosaur Park Formation (RTMP 94.143.1) can be referred to Daspletosaurus on the basis of the number of teeth, but the morphology of the jugal and maxilla is Albertosaurus-like, in several respects.

description: Εισαγωγή: Στην διαδικασία επιλογής πρόσθιων δοντιών η επικρατέστερη θεωρία είναι ότι στρόγγυλα και λεία σχήματα καθώς και κυρτές γραμμές, ως γυναικεία χαρακτηριστικά, πρέπει να χαρακτηρίζουν τις οδοντοστοιχίες των γυναικών. Από την άλλη μεριά οι οδοντοστοιχίες των ανδρών επιβάλλεται να αντανακλούν δύναμη και τόλμη που εκφράζεται με τετράγωνα σχήματα δοντιών.Σκοπός: Αυτή η εργασία εξετάζει αν είναι δυνατό να διακριθεί το φύλο από την οπτική εκτίμηση των έξι φυσικών άνω πρόσθιων δοντιών σε εκμαγεία. Υλικά και μέθοδος: Για την εφαρμογή του ερευνητικού έργου χρησιμοποιήθηκε ένα δείγμα εκμαγείων από 20 άνδρες και 20 γυναίκες. Τα εκμαγεία ανατυπώθηκαν και πληρώθηκαν με σκληρή γύψο. Τα ανατυπωμένα εκμαγεία τροχίστηκαν έτσι ώστε να διατηρηθούν μόνο τα 6 άνω πρόσθια δόντια και αριθμήθηκαν. Τα εκμαγεία δόθηκαν σε 40 κριτές (10 οδοντιάτρους, 10 φοιτητές οδοντιατρικής, 10 οδοντοτεχνίτες και 10 άτομα ανεξάρτητα οδοντιατρικής ειδικότητας) για ν’αναγνωρίσουν το φύλο. Οι παρατηρητές εκτίμησαν τα αριθμημένα εκμαγεία. Ακολούθησε δεύτερη αρίθμηση των εκμαγείων με τυχαία σειρά και δεύτερη εκτίμηση των εκμαγείων. Η περίοδος μεταξύ της πρώτης και της δεύτερης εκτίμησης ήταν δύο εβδομάδες. Οι έλεγχοι πραγματοποιήθηκαν με το Λογισμικό SPSS 14.0 και το επίπεδο στατιστικής σημαντικότητας τέθηκε για P<0.05 Αποτελέσματα:Οι δείκτες συμφωνίας που εξετάστηκαν ήταν προς τρεις άξονες: α)συμφωνία πρώτης και δεύτερης εκτίμησης, β)συμφωνία μεταξύ των διαφορετικών ομάδων κριτών, γ)συμφωνία με την πραγματική κατάσταση. Παρατηρήθηκε ότι και στους τρεις άξονες οι δείκτες κινήθηκαν σε τιμές που αντιστοιχούν σε φτωχή μέχρι σχεδόν μέτρια συμφωνία. Από την άλλη μεριά ο δείκτης ακρίβειας στη διάγνωση-ταξινόμηση που υπολογίστηκε με μεθόδους ROC ανάλυσης έδειξε ότι η εφαρμογή της μεθόδου δεν εξαρτάται από τις διάφορες ομάδες κριτών όπως επίσης δεν εξαρτάται από την επανάληψη της εκτίμησης (1η ή 2η κρίση). Μάλιστα η ακρίβεια της προτεινόμενης μεθόδου σύμφωνα με τους δείκτες της ανάλυσης είναι σε τιμές που πλησιάζουν την τυχαία κρίση. Συμπεράσματα: Οι κριτές και από τις τέσσερις ομάδες δεν μπόρεσαν να εκτιμήσουν σωστά το φύλο σε όλα τα εκμαγεία. Συνεπώς η μέθοδος της οπτικής εκτίμησης δεν μπορεί να χρησιμοποιηθεί για την αναγνώριση του φύλου.
description: This study questions whether upper anterior teeth reflect the gender of a patient. Forty casts of natural teeth were given to forty experts.The experts were asked to assess the gender of the patients.The results of gender identification of the subjects showed that overall the intra-observer and inter-observer agreement were fair. It is concluded, on the basis of this study, experts were unsuccessful in distinguishing the actual sex by visual assesment of upper anterior teeth on casts alone.
Flexible profile approach to the conjugate heat transfer problem

description: The flexible profile approach proposed earlier to create CTM (compact or reduced order thermal models) is extended to cover the area of conjugate heat transfer. The flexible profile approach is a methodology that allows building a highly boundary conditions independent CTM, with any desired degree of accuracy, that may adequately replace detailed 3D models for the whole spectrum of applications in which the modeled object may be used. The extension to conjugate problems radically solves the problem of interfacing two different domains. Each domain, fluid or solid, can be "compacted" independently creating two CTM that can be joined together to produce reliable results for any arbitrary set of external boundary conditions.

description: We argue the sign problem of the fermion determinant at finite density. It is unavoidable not only in Monte-Carlo simulations on the lattice but in the mean-field approximation as well. A simple model deriving from Quantum Chromodynamics (QCD) in the double limit of large quark mass and large quark chemical potential exemplifies how the sign problem arises in the Polyakov loop dynamics at finite temperature and density. In the color SU(2) case our mean-field estimate is in excellent agreement with the lattice simulation. We combine the mean-field approximation with a simple phase reweighting technique to circumvent the complex action encountered in the color SU(3) case. We also investigate the mean-field free energy, from the saddle-point of which we can estimate the expectation value of the Polyakov loop.

description: De Nederlandse overheid streeft ernaar om tegen 2050 volledig circulair te zijn, zoals vastgelegd in het Rijksbrede programma Circulaire Economie. Dit moet leiden tot een aanzienlijke reductie in CO2-uitstoot en materiaalgebruik. Het is echter onduidelijk hoe de transitie naar een circulaire economie precies verloopt. Daarom heeft het Planbureau voor de Leefomgeving (PBL) een werkprogramma opgezet om deze transitie te monitoren en beleidsinformatie te verstrekken. Dit rapport, als onderdeel van de Productgroep Analyse Hernieuwbare Energie Technologieën, onderzoekt de staat van de transitie naar circulaire zonnepanelen, windturbines en autobatterijen in Nederland. Uitgevoerd in samenwerking met de Universiteit Leiden en de Technische Universiteit Delft, biedt het rapport inzichten vanuit het Missie-specifieke Innovatiesysteem (MIS) raamwerk. Het identificeert verschillende oplossingsrichtingen, barrières en beleidsinterventies om de transitie te versnellen. De bevindingen zullen worden gebruikt als input voor de Integrale CE Rapportage 2025.

description: An overview on recent developments in thermal interfaces is given with a focus on a novel thermal interface technology that allows the formation of 2-3 times thinner bondlines with strongly improved thermal properties at lower assembly pressures. This is achieved using nested hierarchical surface channels to control the particle stacking with highly particle-filled materials. Reliability testing with thermal cycling has also demonstrated a decrease in thermal resistance after extended times with longer overall lifetime compared to a flat interface.
