description: Crysogaster virgo Rondani, 1865
ORIGINAL DESCRIPTION: 1865a: 138.
TYPE LOCALITY: “ in Alpibus Insubriae [Insubrian (= Lombardy, Italy) Alps]”.
TYPE MATERIAL: 1 ♀, lectotype (MZUF: Box 6): Lejogaster virgo Rnd., Salò / 295 / Lectotypus Crysogaster (Lejogaster) virgo Rondani, 1865, ♀, des. A. Maibach, 1991 / = Lejogaster metallina (Fabr., 1781), det. A. Maibach, II.1991.
CURRENT STATUS: valid species, as Lejogaster virgo (Peck 1988: 138, Belcari et al. 1995a: 14); junior synonym of Lejogaster metallina (Fabricius, 1781) (Maibach et al. 1994: 258).
REMARKS: Rondani (1865a: 138) described Crysogaster virgo from just the female sex without specifying the number of specimens or the length of the specimens. Maibach et al. (1994: 258) designated a lectotype (♀). Rondani described this nominal species under the generic name Crysogaster, which is an “unjustified emendation of Chrysogaster Meigen, 1803 ” (O’Hara et al. 2011: 66).

Characterizing the dust content of disk substructures in TW Hya
Creators: name: Macías, Enrique
Publisher: name: Zenodo

description: A key piece of information to understand the origin and role of protoplanetary disk substructures is their dust content. In particular, disk substructures associated with gas pressure bumps can work as dust traps, accumulating grains and reaching the necessary conditions to trigger the streaming instability. In order to shed some light on the origin and role that disk substructures play in planet formation, we aim at characterizing the dust content of substructures in the disk of TW Hya. We present Atacama Large Millimeter Array (ALMA) observations of TW Hya at 3.1 mm with ~50 milliarcsecond resolution. This new data were combined with archival high angular resolution ALMA observations at 0.87 mm, 1.3 mm, and 2.1 mm. We analyze this multi-wavelength data to infer a disk radial profile of the dust surface density, maximum particle size, and slope of the particle size distribution. Most previously known disk substructures are resolved at the four wavelengths. Our multi-wavelength analysis of the dust emission shows that the maximum particle size in the disk of TW Hya is >1 mm. The inner 20 au are completely optically thick at all four bands, which results in the data tracing different disk heights at different wavelengths. Coupled with the effects of dust settling, this prevents the derivation of accurate density and grain size estimates in these regions. At r>20 au, we find evidence of the accumulation of large dust particle at the position of the bright rings, indicating that these are working as dust traps. The total dust mass in the disk is between 250 and 330 M?, which represents a gas-to-dust mass ratio between 50 and 70. Our mass measurement is a factor of 4.3-5.7 higher than the mass that one would estimate using the typical assumptions of large demographic surveys. Overall, our results indicate that the ring substructures in TW Hya are ideal locations to trigger the streaming instability and form new generations of planetesimals.

description: Simulated hydroclimate variability in millennium-length forced transient and control simulations from the ECHAM and the global Hamburg Ocean Primitive Equation (ECHO-G) coupled atmosphere–ocean general circulation model (AOGCM) is analyzed and compared to 1000 years of reconstructed Palmer drought severity index (PDSI) variability from the North American Drought Atlas (NADA). The ability of the model to simulate megadroughts in the North American southwest is evaluated. (NASW: 25°–42.5°N, 125°–105°W). Megadroughts in the ECHO-G AOGCM are found to be similar in duration and magnitude to those estimated from the NADA. The droughts in the forced simulation are not, however, temporally synchronous with those in the paleoclimate record, nor are there significant differences between the drought features simulated in the forced and control runs. These results indicate that model-simulated megadroughts can result from internal variability of the modeled climate system rather than as a response to changes in exogenous forcings. Although the ECHO-G AOGCM is capable of simulating megadroughts through persistent La Niña–like conditions in the tropical Pacific, other mechanisms can produce similarly extreme NASW moisture anomalies in the model. In particular, the lack of low-frequency coherence between NASW soil moisture and simulated modes of climate variability like the El Niño–Southern Oscillation, Pacific decadal oscillation, and Atlantic multidecadal oscillation during identified drought periods suggests that stochastic atmospheric variability can contribute significantly to the occurrence of simulated megadroughts in the NASW. These findings indicate that either an expanded paradigm is needed to understand multidecadal hydroclimate variability in the NASW or AOGCMs may incorrectly simulate the strength and/or dynamics of the connection between NASW hydroclimate variability and the tropical Pacific.

description: In this contribution, we study the time lag between the local expenditures of European funds by beneficiaries in Italian regions and the corresponding payments reported in the European Commission (EC) database. We propose a model to reconstruct the timing of these local expenditures by back-dating the observed EC reimbursements. Our estimates are validated against the expenditures reported from the Italian National managing Authority (NMA) in terms of cumulative monetary difference over the years of the programming period inquired: The lower cumulative yearly distance of our modelled expenditures in comparison with the official \ac{ec} payments confirms the robustness of our model. The importance of the modelling parameters on the cumulative distance between the reported NMA and modelled expenditures is then analysed through sensitivity analysis. The parameters mostly affecting the uncertainty of the output variable are: i) how the non-clearly regionalised expenditures are attributed to individual regions; and ii) the number of backward years on which the residuals of the yearly payments are spread onto. In general, the distance between the modelled and reported expenditures can be further reduced by fixing these parameters, although the gain is only marginal for some regions. The present study paves the way to modelling exercises aimed at more reliable estimates of the expenditures on the ground by the ultimate beneficiaries. The proposed data base has great potential to enhance the reliability of econometric studies on cohesion policies.
Resolving the problem of galaxy clustering on small scales: any new physics needed?

description: Galaxy clustering sets strong constraints on the physics governing galaxy formation and evolution. However, most current models fail to reproduce the clustering of low-mass galaxies on small scales ($r<1Mpc/h$). In this paper we study the galaxy clusterings predicted from a few semi-analytical models. We firstly compare two Munich versions, Guo et al. (2011, Guo11) and De Lucia \& Blazoit (2007, DLB07). The Guo11 model well reproduces the galaxy stellar mass function, but over-predicts the clustering of low-mass galaxies on small scales. The DLB07 model provides a better fit to the clustering on small scales, but over-predicts the stellar mass function. These seem to be puzzling. We find that there is slightly more fraction of satellite galaxies residing in massive haloes in the Guo11 model, which is the dominant contribution to the clustering discrepancy between the two models. However, both models still over-predict the clustering at $0.1Mpc/h

description: Dans ce mémoire, nous nous penchons sur le rôle de la créativité lors de l’apprentissage des Mathématiques à l’école obligatoire. La grande difficulté en Mathématiques éprouvée par une partie des élèves, trouve-t-elle sa source dans une perception de cette matière, vue comme non-créative, inhibant ainsi leur potentiel créatif, pourtant clé de leur réussite ? Dans ce cas, cet obstacle constituerait une sorte de barrière mentale, dont la suppression deviendrait une des priorités pour l’enseignant soucieux d’optimiser les progrès de ces élèves. Pour vérifier l’existence d’un tel obstacle, nous avons utilisé le même test, basé sur un dessin, adapté à partir du Test for Creative Thinking - Drawing Production (TCT-DP) d’Urban, pour mesurer de manière différenciée la créativité des élèves dans les contextes du cours de Mathématiques, et du cours d’Arts Visuels, pour vérifier si une différence significative pouvait être observée entre ces deux cas dans trois classes différentes : une classe de 8H, une classe de 11H voie générale niveau 1 (11VG) ainsi qu’une classe de 11H voie prégymnasiale (11VP). Complétant ces résultats, les élèves ont répondu à deux questionnaires différents comportant notamment l’évaluation de l’estime de soi sur l’échelle de Rosenberg, ainsi que des questions ouvertes les interrogeant sur le sens que les élèves attribuent à l’apprentissage en général, aux Mathématiques, aux Sciences et aux Arts Visuels. Les résultats des tests créatifs mettent en évidence une différence significative entre les scores créatifs dans les deux contextes pour la classe de 8H, mais pas pour les classes de 11VG et 11VP. Une différence significative apparaît entre la classe de 11VP et les deux autres classes pour le score créatif dans le contexte en Mathématiques, ainsi que pour le score d’estime de soi. Ces résultats montrent que la perception des Mathématiques n’est pas la même selon les orientations, et qu’au niveau 8H, dans lequel se décide justement l’orientation pour le Secondaire I, il existe une différence de perception entre les Mathématiques et une matière artistique comme les Arts Visuels. Cette différence pourrait avoir une relation avec l’estime de soi.

The role of closeness in the relationship between nonverbal mimicry and cooperation
Creators: name: Marono, Abbie
Publisher: name: Lancaster University
Year: 2022

description: The ‘social glue’ function of nonverbal mimicry has received much support in the empirical literature, with research demonstrating its prosocial consequences, including increased cooperation. When looking to explain why nonverbal mimicry effects behaviour, some research has pointed to interpersonal closeness. However, in these studies, a robust measurement of nonverbal mimicry and closeness is absent, making it impossible to confidently argue that the observed mimicry resulted from increased closeness and not a third factor. Likewise, without a reliable measure of nonverbal mimicry it is not possible to determine that nonverbal mimicry was manipulated sufficiently. This thesis addresses this by testing the impact of nonverbal mimicry on cooperation through closeness, using rigorous measures. In chapter 3 I use high-resolution motion tracking—Xsens MVN systems—todemonstrate that an increased closeness towards a partner is associated with more nonverbal mimicry of that partner. It also identified regions of mimicry (discreet body movements) that are related to closeness. Chapter 4 showed a positive relationship between nonverbal mimicry and closeness but found no mediation effect of closeness on the relationship between mimicry and cooperation. In chapter 5, I controlled for methodological limitations in Chapter 4 and found a positive relationship between nonverbal mimicry and cooperation andsupported a mediating effect of closeness. Extending beyond mimicry within the dyad, chapter 6 showed that third-party observers would be more willing to engage in conversation with dyads who showed increased nonverbal mimicry compared to lower amounts of nonverbal mimicry. The effects of third-party nonverbal mimicry were mediated by closeness towards the dyad. Overall, this thesis provides robust evidence for closeness as one of the psychological mechanisms underpinning how nonverbal mimicry works to increase cooperation and provides new insight into the relationship between nonverbal mimicry and social judgements.

description: Substructures are known to be good tracers for the dynamical states and recent accretion histories of the most massive collapsed structures in the Universe, galaxy clusters. Observations find extremely massive substructures in some clusters, especially Abell 2744, which are potentially in tension with the $Λ$CDM paradigm since they are not found in simulations directly. However, the methods to measure substructure masses strongly differ between observations and simulations. Using the fully hydrodynamical cosmological simulation suite Magneticum Pathfinder we develop a method to measure substructure masses in projection from simulations, similar to the observational approach. We identify a simulated Abell 2744 counterpart that not only has eight substructures of similar mass fractions but also exhibits similar features in the hot gas component. This cluster formed only recently through a major merger together with at least 6 massive minor merger events since z=1, where prior the most massive component had a mass of less than $1\times10^{14}M_\odot$. We show that the mass fraction of all substructures and of the eighth substructure separately are excellent tracers for the dynamical state and assembly history for all galaxy cluster mass ranges, with high fractions indicating merger events within the last 2Gyr. Finally, we demonstrate that the differences between subhalo masses measured directly from simulations as bound and those measured in projection are due to methodology, with the latter generally 2-3 times larger than the former. We provide a predictor function to estimate projected substructure masses from SubFind masses for future comparison studies between simulations and observations.

description: A series of European geoid and quasigeoid models was computed at Institut für Erdmessung (IfE) with support of the International Association of Geodesy (IAG), presently in the form of IAG Sub-Commission 2.4a “Gravity and Geoid in Europe”. The last major re-computation was performed in 2008 and is denoted as EGG2008 (European Gravimetric Geoid 2008). Since that time, several important developments have taken place, including five releases of GOCE global gravity field models, the availability of a number of new gravity field data sets, as well as some improvements in the modeling approach, especially regarding the rigorous linearization of the observation equations with respect to a high-degree reference model. The present contribution takes the aforementioned refinements into account and discusses the results of corresponding re-computations of the quasigeoid in Europe. The new models are evaluated by different national and European GPS and levelling data sets, where emphasis is put on the effect of the data updates and the modeling refinements. Furthermore, applications of the quasigeoid models are outlined regarding vertical datum connections and the delivery of ground truth data for high-precision optical clock comparisons. The latter topic relates to the presently developed new generation of optical clocks with a projected relative accuracy of 10^{-17} to 10^{-18}, which (according to the laws of general relativity) corresponds to a sensitivity in the gravity potential equivalent 0.1 m to 0.01 m in height, respectively. Once such optical clocks become operational, this would open several interesting applications in geodesy, such as the large-scale control of height systems and gravity field models as well as the interconnection of tide gauges.

ORIGINAL DESCRIPTION: 1851: 358.
TYPE LOCALITY: “ Brasile [Brazil]” (Rondani, 1848b: 69) [type locality for Eristalis cognatus Rondani, 1848]; [Belem (Pará), Brazil] (Papavero 1973: 343). See Remarks.
TYPE MATERIAL: 1 ♂, syntype (missing right hind-leg) (MZUF: Box 72): Eristalomya agnata Rnd., Brasil / Brasil / [no identification number]; 1 ♂, syntype (MZUN: Box Coll. entomol. extra-europea, Fam. Sirfidei - Gen. Dolichomerus a Meromacrus): Eristalomya agnata Rnd., Brasile / M. Zool. N° 11239 / ♂.
CURRENT STATUS: junior synonym of Palpada scutellaris (Fabricius, 1805) (Thompson et al. 1976: 109).
REMARKS: Rondani (1848b: 69) described Eristalis cognatus from just the male sex, without specifying the exact number of specimens, from material collected in South America by V. Ghiliani. Rondani (1851: 358) proposed the new replacement name Eristalis agnatus for Eristalis cognatus, preoccupied by Wiedemann (1824: 37). Costa (1866: 31) listed a single MZUN specimen, as Eristalomyia agnata, numbered “621”. We found two syntypes in this study. Although Rondani (1848b: 63) only gave the type locality as “ Brasile ”, Papavero (1973: 343) gave a more accurate type locality based on a note in Spinola (1853) that said all specimens collected by Ghiliani in 1846 were collected in Belem, Pará, Brazil.

description: Two-point current correlation functions of the large $N$ limit of supersymmetric and non-supersymmetric Yang-Mills theories at strong coupling are investigated in terms of their string theory dual models with quenched flavors. We consider non-Abelian global symmetry currents, which allow one to investigate vector mesons with $N_f > 1$. From the correlation functions we construct the deep inelastic scattering hadronic tensor of spin-one mesons, obtaining the corresponding eight structure functions for polarized vector mesons. We obtain several relations among the structure functions. Relations among some of their moments are also derived. Aspects of the sub-leading contributions in the $1/N$ and $N_f/N$ expansions are discussed. At leading order we find a universal behavior of the hadronic structure functions.

description: In neural networks, task-relevant information is represented jointly by groups of neurons. However, the specific way in which this mutual information about the classification label is distributed among the individual neurons is not well understood: While parts of it may only be obtainable from specific single neurons, other parts are carried redundantly or synergistically by multiple neurons. We show how Partial Information Decomposition (PID), a recent extension of information theory, can disentangle these different contributions. From this, we introduce the measure of "Representational Complexity", which quantifies the difficulty of accessing information spread across multiple neurons. We show how this complexity is directly computable for smaller layers. For larger layers, we propose subsampling and coarse-graining procedures and prove corresponding bounds on the latter. Empirically, for quantized deep neural networks solving the MNIST and CIFAR10 tasks, we observe that representational complexity decreases both through successive hidden layers and over training, and compare the results to related measures. Overall, we propose representational complexity as a principled and interpretable summary statistic for analyzing the structure and evolution of neural representations and complex systems in general.

Vertical Shear Instability and Photoevaporative Winds

Publisher: name: Zenodo
Year: 2020

description: In recent years hydrodynamical (HD) models have become important to describe the gas kinematics in protoplanetary disks, especially in combination with models of photoevaporation and/or magnetically driven winds. Our aim is to investigate how vertical shear instability (VSI) could influence the thermally driven winds on the surface of protoplanetary disks.
 In this first part of the project, we focus on diagnosing the conditions of the VSI at the highest numerical resolution ever recorded, and suggest at what resolution per scale height we obtain convergence. At the same time, we want to investigate the vertical extent of VSI activity. Finally, we determine the regions where extreme UV (EUV), far-UV (FUV), and X-ray photons are dominant in the disk.
 We perform global HD simulations using the PLUTO code. We adopt a global isothermal accretion disk setup, 2.5D (2 dimensions, 3 components) which covers a radial domain from 0.5 to 5.0 and an approximately full meridional extension. Our simulation runs cover a resolution from 12 to 203 cells per scale height.
 We determine 50 cells per scale height to be the lower limit to resolve the VSI. For higher resolutions, >50 cells per scale height, we observe the convergence for the saturation level of the kinetic energy. We are also able to identify the growth of the ``body'' modes, with higher growth rate for higher resolution. Full energy saturation and a turbulent steady state is reached after 70 local orbits. We determine the location of the EUV heated region defined by $\Sigma_{r}$=10$^{19}$ cm$^{-2}$ to be at $H_\mathrm{R}\sim9.7$ and the FUV--X-ray heated boundary layer defined by $\Sigma_{r}$=10$^{22}$ cm$^{-2}$ to be at $H_\mathrm{R}\sim6.2$, making it necessary to introduce a hot atmosphere. For the first time we report the presence of small-scale vortices in the $r-Z$ plane between the characteristic layers of large-scale vertical velocity motions. Such vortices could lead to dust concentration, promoting grain growth. Our results highlight the importance of combining photoevaporation processes in the future high-resolution studies of turbulence and accretion processes in disks.

description: Cancer diagnosis is performed by extracting a tissue specimen from the suspicious area. The tissue specimen is retrieved by trans-urethral resection of the bladder tumor. This specimen undergoes histopathological processes to create a glass slide for pathological examination. Handling the specimen through various stages requires histotechnical expertise to avoid introducing artifacts. Whole Slide Images (WSI) are high-resolution scans of glass slides with the potential of automated diagnostics using computational pathology (CPATH) systems.
 However, the presence of artifacts in the WSI may cause false predictions by CPATH systems, leading to an incorrect diagnosis. Detecting and eliminating all artifacts will leave diagnostically relevant regions for accurate prediction and save the time of manual Quality Control (QC) inspection. Artifacts such as blood on the tissue result from hemorrhage or vessel rupture, while damaged tissue is a complication caused by specimen collection procedures in bladder cystoscopy [2]. Air bubbles can appear on a glass slide due to improper mounting and leave a fainted appearance on the tissue. In this work, we focus on detecting three notable artifacts; blood, damage, and air bubbles. We are using a supervised learning approach to train several Convolutional Neural Network (CNN) architectures for artifact detection.

description: In this paper, we consider robust stability analysis of large-scale sparsely interconnected uncertain systems. By modeling the interconnections among the subsystems with integral quadratic constraints, we show that robust stability analysis of such systems can be performed by solving a set of sparse linear matrix inequalities. We also show that a sparse formulation of the analysis problem is equivalent to the classical formulation of the robustness analysis problem and hence does not introduce any additional conservativeness. The sparse formulation of the analysis problem allows us to apply methods that rely on efficient sparse factorization techniques, and our numerical results illustrate the effectiveness of this approach compared to methods that are based on the standard formulation of the analysis problem.

description: The commenters confirm the errors identified and discussed in Smerdon et al., which either invalidated or required the reinterpretation of quantitative results from pseudoproxy experiments presented or used in several earlier papers. These errors have a strong influence on the spatial skill assessments of climate field reconstructions (CFRs), despite their small impacts on skill statistics averaged over the Northern Hemisphere. On the basis of spatial performance and contrary to the claim by the commenters, the Regularized Expectation Maximization method using truncated total least squares (RegEM-TTLS) cannot be considered a preferred CFR technique. Moreover, distinctions between CFR methods in the context of the discussion in the original paper are immaterial. Continued investigations using accurately described and faithfully executed pseudoproxy experiments are critical for further evaluation and improvement of CFR methods.

description: (Abridged) Dust is expected to be ubiquitous in extrasolar planetary systems owing to the dynamical activity of minor bodies. Inner dust populations are, however, still poorly known because of the high contrast and small angular separation with respect to their host star. We aim to determine the level of near-infrared exozodiacal dust emission around a sample of 42 nearby main sequence stars with spectral types ranging from A to K and to investigate its correlation with various stellar parameters and with the presence of cold dust belts. We use high-precision K-band visibilities obtained with the FLUOR interferometer on the shortest baseline of the CHARA array. The calibrated visibilities are compared with the expected visibility of the stellar photosphere to assess whether there is an additional, fully resolved circumstellar emission. Near-infrared circumstellar emission amounting to about 1% of the stellar flux is detected around 13 of our 42 target stars. Follow-up observations showed that one of them (eps Cep) is associated with a stellar companion, while another one was detected around what turned out to be a giant star (kap CrB). The remaining 11 excesses found around single main sequence stars are most probably associated with hot circumstellar dust, yielding an overall occurrence rate of 28+8-6% for our (biased) sample. We show that the occurrence rate of bright exozodiacal discs correlates with spectral type, K-band excesses being more frequent around A-type stars. It also correlates with the presence of detectable far-infrared excess emission in the case of solar-type stars. This study provides new insight into the phenomenon of bright exozodiacal discs, showing that hot dust populations are probably linked to outer dust reservoirs in the case of solar-type stars. For A-type stars, no clear conclusion can be made regarding the origin of the detected near-infrared excesses.

description: Eristalis pascuorum Rondani, 1857
ORIGINAL DESCRIPTION: 1857: 39 (key), 41 (description).
TYPE LOCALITY: “ Österreich … auch hier [Austria … also here (presumably Stolberg near Aachen in Germany where Meigen lived)]” (Meigen 1822: 393) [type locality for Eristalis pratorum Meigen, 1822].
TYPE MATERIAL: see Remarks.
CURRENT STATUS: junior synonym of Eristalis pratorum Meigen, 1822 (Peck 1988: 189, Belcari et al. 1995a: 17); junior synonym of Eristalis similis (Fallén, 1817) (Hippa et al. 2001: 318).
REMARKS: Rondani (1857: 41) moved Syrphus pratorum Fabricius, 1775 to the genus Eristalis Latreille, 1804 and proposed the new replacement name Eristalis pascuorum for Eristalis pratorum Meigen, 1822, preoccupied by Fabricius (18775: 765). The type material for Eristalis pascuorum will be the same as for the name it was proposed to replace, i. e., Eristalis pratorum. The holotype of this latter species is preserved in the MNHN (Muséum national d’Histoire naturelle 2020). Under the name Eristalis pascuorum there are one male and one female in the MSNC and two specimens in the MZUB (non-types).

On dust evolution in planet-forming discs in binary systems
Creators: name: Zagaria, Francesco
Publisher: name: Zenodo
Year: 2020

description: The vast majority of stars are in binaries or higher-order multiple stellar systems. Although in recent years a large number of binaries have been proven to host exoplanets, how planet formation proceeds in multiple stellar systems has not been studied yet with the necessary insight from the theoretical standpoint. Our aim is to fill this gap, focusing on the evolution of the dust grains in planet-forming discs in binaries. We take into account the dynamics of the gas and the dust in discs around each component of a binary system under the hypothesis that the evolution of the circumprimary and the circumsecondary discs is independent. It is known from previous theoretical and numerical studies that the secular evolution of the gas in binary discs is hastened due to the tidal interactions with their hosting stars. Here we prove that binarity affects dust dynamics too, possibly in a more dramatic way than in the case of the gas. In particular, the presence of a stellar companion significantly reduces the amount of grains retained in binary discs because of a faster, more efficient radial drift, ultimately shortening their lifetime. We prove that how rapidly discs disperse depends both on the binary separation, with discs in wider binaries living longer, and on the disc viscosity. Although the less-viscous discs lose high amounts of solids in the earliest stages of their evolution, they are dissipated slowly, while those with higher viscosities show an opposite behaviour. The faster radial migration of solids in binary discs has a striking impact on planet formation, which seems to be inhibited in this hostile environment, unless other disc substructures halt radial drift further in. We conclude that planet formation in multiple stellar systems is likely to take place on very short time scales. As a post-processing step, we compute disc dust sizes from our models at ALMA wavelengths and compare them with the results of the multiple stellar disc surveys in Taurus and ? Ophiuchus. We show that radial drift naturally explains the observed disc dust sizes without invoking very high eccentricities as previously assumed.

description: This thesis by publication explored the central research aim to understand and enhance work readiness in psychology students studying online. The project filled a literature gap relating to understanding psychological work readiness in an Australian context. Three key outcomes are noted. Firstly, a psychologically oriented definition of work readiness was developed. Secondly, the who, what and where of work readiness in psychology was explored via qualitative methods, and was a first-on-its-kind review in the psychological education space. Finally, recommendations for increasing psychological work readiness were proposed centering on the need for increased awareness and understanding of skill development during educational pathways.

description: Materials can, in principle, be imaged at the level of individual atoms with aberration corrected transmission electron microscopy. However, such resolution can be attained only with very high electron doses. Consequently, radiation damage is often the limiting factor when characterizing sensitive materials. Here, we demonstrate a simple and effective method to increase the electron radiation tolerance of materials by using graphene as protective coating. This leads to an improvement of three orders of magnitude in the radiation tolerance of monolayer MoS2. Further on, we construct samples in different heterostructure configurations to separate the contributions of different radiation damage mechanisms.

Eristalis proximus

description: Eristalis proximus Rondani, 1848
ORIGINAL DESCRIPTION: 1848b: 69.
TYPE LOCALITY: “ Brasile [Brazil]” (Rondani 1848b: 63); [Belem (Pará), Brazil] (Papavero 19073: 343). See Remarks.
TYPE MATERIAL: not found in this study.
CURRENT STATUS: junior synonym of Palpada fasciata (Wiedemann, 1819) (Thompson et al. 1976: 105); junior primary homonym of Eristalis proxima Zetterstedt, 1843 (Evenhuis & Pape 2020).
REMARKS: Rondani (1848b: 69) described Eristalis proximus, without specifying the number, the sex or the length of the specimens, from material collected in South America by V. Ghiliani. Although Rondani (1848b: 63) only gave the type locality as “ Brasile ”, Papavero (1973: 343) gave a more accurate type locality based on a note in Spinola (1853) that said all specimens collected by Ghiliani in 1846 were collected in Belem, Pará, Brazil. This is one of the few exotic species described in Rondani (1848b) that Costa (1866) did not list as in the MZUN. We could not locate any type specimens of this nominal species in our study.

description: Digital pathology (DP) refers to the use of a virtual microscope for the digital scanning of tissue slides, producing Whole-slide Images (WSI). WSIs are very high-resolution and information-rich. Different laboratories and scanners can have slightly different protocols and color variations that can be present even within the same lab and scanner. A WSI can contain a variety of artifacts. These artifacts may result from the tissue being cauterized or from the preparation of the slide. We propose a preprocessing pipeline to cover necessary steps and filters to detect regions of the WSI that should be discarded before further processing with machine learning models.

description: Context. Some microquasars exhibit millisecond quasi-periodic oscillations (QPO) that are likely related to phenomena occuring in the immediate vicinity of the central black hole. Oscillations of accretion tori have been proposed to model these QPOs. Aims. Here, we aim at determining the observable spectral signature of slender accretion tori surrounding Kerr black holes. We analyze the impact of the inclination and spin parameters on the power spectra. Methods. Ray-traced power spectra of slender tori oscillation modes are computed in the Kerr metric. Results. We show that the power spectral densities of oscillating tori are very sensitive to the inclination and spin parameters. This strong dependency of the temporal spectra on inclination and spin may lead to observable constraints of these parameters. Conclusions. This work goes a step further in the analysis of the oscillating torus QPO model. It is part of a long-term study that will ultimately lead to comparison with observed data.

description: Despite the importance of reading literacy in adulthood, research in this field in Spanish-speaking countries is limited due to the lack of a valid tool to assess adults’ reading comprehension in their native language. Thus, we aimed to adapt the Deep Cloze test by Jensen and Elbro (2022) to Spanish and validate it. 453 undergraduate students from the universities of Valencia and Zaragoza completed the Spanish version of the Deep Cloze test. In addition, to test its criterion validity, subsets of the sample completed other text comprehension measures or provided their grades in introductory courses four months after completing the Deep Cloze test. Results indicated that while the Deep Cloze test has good internal consistency, correlations with other text comprehension measures and grades on a final exam are mostly small. The Deep Cloze fills an important gap by facilitating the assessment of reading comprehension efficiency in Spanish undergraduate students. This test presents important advantages, such as simplicity and administration time, and it can be used for research purposes. Finally, we discuss future research needed to test its validity to be used as a diagnostic tool to help deliver targeted support to struggling adult readers.
