description: We present SCExAO/CHARIS 1.1--2.4 micron integral field direct spectroscopy of the young HIP 79124 triple system. HIP 79124 is a member of the Scorpius-Centaurus association, consisting of an A0V primary with two low-mass companions at a projected separation of <1 arcsecond. Thanks to the high quality wavefront corrections provided by SCExAO, both companions are decisively detected without the employment of any PSF-subtraction algorithm to eliminate quasi-static noise. The spectrum of the outer C object is very well matched by Upper Scorpius M4 pm 0.5 standard spectra, with a Teff = 2945 pm 100 and a mass of 350 MJup. HIP 79124 B is detected at a separation of only 180 mas in a highly-correlated noise regime, and it falls in the spectral range M6 pm 0.5 with Teff = 2840 pm 190 and 100 MJup. Previous studies of stellar populations in Sco-Cen have highlighted a discrepancy in isochronal ages between the lower-mass and higher-mass populations. This could be explained either by an age spread in the region, or by conventional isochronal models failing to reproduce the evolution of low-mass stars. The HIP 79124 system should be coeval, and therefore it provides an ideal laboratory to test these scenarios. We place the three components in a color-magnitude diagram and find that the models predict a younger age for the two low-mass companions (3 Myr) than for the primary star (6 Myr). These results imply that the omission of magnetic effects in conventional isochronal models inhibit them from reproducing early low-mass stellar evolution, which is further supported by the fact that new models that include such effects provide more consistent ages in the HIP 79124 system.

description: In Lehre und Rechtsprechung ist anerkannt, dass ein zivilrechtliches Urteil nicht nur fehlerhaft, sondern unter bestimmten Bedingungen sogar wirkungslos bzw. nichtig sein kann. Ebenfalls hält ein großer Teil von Schrifttum und Rechtsprechung die Feststellungsklage gem. § 256 ZPO für einen zulässigen Rechtsbehelf zur Entscheidung über die Urteilsnichtigkeit. Obwohl deshalb der Eindruck entstehen mag, dass die Zulässigkeit der Feststellungsklage bei nichtigen Urteilen weitestgehend unproblematisch ist, wird man bei näherer Betrachtung bemerken, dass schon nicht ohne weiteres ersichtlich ist, was in diesem Fall der richtige Feststellungsgegenstand ist. Schließlich ist das Rechtsverhältnis i.S.v. § 256 ZPO nach allgemeiner Ansicht eine auf einem konkreten Sachverhalt beruhende rechtliche Beziehung einer Person zu einer anderen Person oder Sache. Hinsichtlich der Feststellungsgegenstände „Urteil“ oder „Urteilsnichtigkeit“ erscheint jedoch fraglich, inwiefern diese Tatbestände eine rechtliche Beziehung darstellen. Unter anderem aus diesem Grund gibt es auch Gegenstimmen, die sich gegen die Feststellungsklage nach § 256 ZPO als zulässige Rechtsschutzmöglichkeit gegen nichtige Urteile wenden. Im ersten Teil der Arbeit war deshalb zu untersuchen, ob die Feststellungsklage nach § 256 ZPO grundsätzlich einen statthaften Rechtsbehelf gegen wirkungslose Urteile darstellt und ob das Urteil, seine Nichtigkeit oder gar ein aus der Wirkungslosigkeit des Urteils abzuleitendes Rechtsverhältnis Gegenstand einer Klage nach § 256 ZPO sein können. Im zweiten Teil der Arbeit war sodann der Frage nachzugehen, unter welchen Umständen ein Interesse an der Feststellung der Urteilnichtigkeit bzw. eines aus der Urteilsnichtigkeit abzuleitenden Rechtsverhältnisses bestehen kann. Auch wenn das Feststellungsinteresse als besondere Zulässigkeitsvoraussetzung der Feststellungsklage grundsätzlich stark vom Einzelfall abhängig ist, lassen sich doch gewisse Konstellationen erdenken, in denen ein Bedürfnis nach Rechtssicherheit und Klarheit im Hinblick auf die Nichtigkeit des Urteils entsteht. So wird etwa der Schuldner die Vollstreckung aus einem wirkungslosen und damit auch nicht vollstreckbaren Titel verhindern wollen und deshalb anstreben, Zweifel über die Wirksamkeit mit Hilfe der Klage nach § 256 ZPO auszuräumen. Ob dieser oder ähnliche Gründe gerade die Klageerhebung nach § 256 ZPO und damit auch eine Belastung des Beklagten rechtfertigen können oder ob womöglich andere Klagearten oder Rechtsbehelfe effektiveren Rechtsschutz bieten, war in dieser Arbeit zu klären.

description: Σκοπός: Η ταχύτητα της ανάπτυξης και της εφαρμογής των ψηφιακών τεχνολογιών και των μεγάλων δεδομένων στην κτηνιατρική οδηγεί σε νέες ευκαιρίες στην κτηνιατρική επιδημιολογία για το πώς να μεταφραστούν τα άφθονα, ποικίλα και ταχέως αναπτυσσόμενα «μεγάλα» δεδομένα σε ουσιαστικές γνώσεις για τη δημόσια υγεία. Σε αυτό το πλαίσιο σκοπός της εργασίας είναι να αναδειχθεί η αξιοποίηση των μεγάλων δεδομένων στον τομέα της κτηνιατρικής, δίνοντας έμφαση στη συνταγογράφηση κτηνιατρικών φαρμακευτικών προϊόντων, ώστε να προσδιοριστούν τα στοιχεία που θα πρέπει να απαρτίζουν μία βάση δεδομένων για την ηλεκτρονική καταχώρηση και εκτέλεση συνταγών κτηνιατρικών φαρμάκων. Υλικό-Μέθοδος: Για την παρούσα μελέτη χρησιμοποιήθηκε η μέθοδος της βιβλιογραφικής ανασκόπησης και η ανάλυση των δευτερογενών δεδομένων από πηγές διαδικτύου. Επίσης έγινε επιθεώρηση και αναφορά του σύγχρονου Εθνικού και Ευρωπαϊκού νομοθετικού πλαισίου σχετικά με την κυκλοφορία κτηνιατρικών φαρμακευτικών προϊόντων και της συνταγογράφησης τους. Αποτελέσματα: Διαπιστώθηκε πως στην Ελλάδα υπάρχουν διάφορες βάσεις δεδομένων που αφορούν τον κτηνιατρικό τομέα (ΟΣΔΕ, ΟΠΣ-Κ, ΕΜΖΣ), οι οποίες λειτουργούν ανεξάρτητα και οδηγούν σε μια σειρά προβλημάτων, όπως ηλεκτρονική απομόνωση, διπλή καταγραφή και μη αξιοποίηση πληροφοριών. Προκειμένου να αντιμετωπιστούν τα προβλήματα που δημιουργεί η αποσπασματικότητα των βάσεων δεδομένων, προτείνεται η δημιουργία ενός ενιαίου συστήματος διαχείρισης δεδομένων, το οποίο θα συμβάλει στην αποτελεσματικότερη λειτουργία των κτηνιατρικών υπηρεσιών με την παροχή υψηλότερης ποιότητας υπηρεσιών. Η ενοποίηση των βάσεων δεδομένων, θα δημιουργήσει ένα ενιαίο σημείο πρόσβασης σε όλες τις πληροφορίες του κτηνιατρικού τομέα και μπορεί να επιτευχθεί μέσω της δημιουργίας ενός Εθνικού Συστήματος Πληροφοριών Κτηνιατρικής που θα αποτελέσουν πολύτιμο εργαλείο για την έγκυρη λήψη αποφάσεων, θα συμβάλλει στην υιοθέτηση ταχέων και αποτελεσματικών μέτρων παρέμβασης και προστασίας του περιβάλλοντος και της δημόσιας υγείας.

description: Deformations of the Lie algebras so(4), so(3,1), and e(3) that leave their so(3) subalgebra undeformed and preserve their coset structure are considered. It is shown that such deformed algebras are associative for any choice of the deformation parameters. Their Casimir operators are obtained and some of their unitary irreducible representations are constructed. For vanishing deformation, the latter go over into those of the corresponding Lie algebras that contain each of the so(3) unitary irreducible representations at most once. It is also proved that similar deformations of the Lie algebras su(3), sl(3,R), and of the semidirect sum of an abelian algebra t(5) and so(3) do not lead to associative algebras.

description: It is important to understand current trends in cancer risk among people living with HIV (PLWH) to improve outcomes and to commission and delivery appropriate services. Nationwide, population-based, matched cohort study on all adult PLWH treated at Danish HIV health care centres since 1 January 1995 and a comparison cohort, randomly selected from the background population and matched on sex and date of birth. We included 6327 PLWH and 63,270 individuals in the comparison cohort − 74% were men and median age was 37 (interquartile range: 30–46). For both smoking related cancers, virological cancers and other cancers, incidence was substantially higher in the first year of observation for PLWH than for the remaining observation period. The risk of smoking related cancer remained stably increased throughout the observation period, whereas the relative risk of virological cancers decreased, especially in the first year of follow up. Finally, the risk of other cancers for PLWH decreased to a level below that of the background population during the study period. The fact that the risk of other cancers was probably not higher among PLWH than in the comparison cohort is encouraging, as the excess risk of virological and smoking related cancers is potentially preventable by timely treatment of HIV and smoking cessation.

Year: 1998
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: The lifetime of the Bs0 meson is measured using the semileptonic decay Bs0 --> Ds- l+ nu X. The data sample consists of about 110 pb^-1 of pp= collisions at sqrt{s} = 1.8 TeV collected by the CDF detector at Fermilab. Four different Ds- decay modes are reconstructed resulting in approximately 600 Ds-l+ signal events. The Bs0 meson lifetime is determined to be tau(Bs0) = (1.36 +- 0.09 +0.06-0.05) ps, where the first and second uncertainties are statistical and systematic, respectively. The Bs0 meson decay length distribution is examined for a lifetime difference Delta_Gamma/Gamma between the two mass eigenstates of the Bs0 meson. An upper limit of Delta_Gamma/Gamma < 0.83 is set at 95% confidence level.

description: We describe the correspondence of the Matsuo-Cherednik type between the quantum $n$-body Ruijsenaars-Schneider model and the quantum Knizhnik-Zamolodchikov equations related to supergroup $GL(N|M)$. The spectrum of the Ruijsenaars-Schneider Hamiltonians is shown to be independent of the ${\mathbb Z}_2$-grading for a fixed value of $N+M$, so that $N+M+1$ different qKZ systems of equations lead to the same $n$-body quantum problem. The obtained results can be viewed as a quantization of the previously described quantum-classical correspondence between the classical $n$-body Ruijsenaars-Schneider model and the supersymmetric $GL(N|M)$ quantum spin chains on $n$ sites.

Magnetic Susceptibility of the Orbitally Degenerate (J= 5/2) Periodic Anderson Model - Analysis on the Basis of the Fermi Liquid Theory

Year: 1996

subject: FOS: Physical sciences

description: In the orbitally degenerate ($J=5/2$) Periodic Anderson Model, the magnetic susceptibility is composed of both the Pauli term and the Van Vleck term, as is well known. The former is strongly enhanced by the strong correlation between $f$-electrons. But, for the latter, the influence of the strong correlation has been obscure for years. In this paper we give the solution of the longstanding problem. With the aid of the $d=\infty$ approximation, we study this problem on the basis of the Fermi liquid theory with degenerate orbitals, taking account of all the vertex corrections in a consistent way. As a result, we obtain the simple expression for the magnetic susceptibility, and show unambiguously that the Van Vleck term is also highly enhanced} in the strong correlation regime. This fact explains naturally the enhanced magnetic susceptibility observed in many insulating systems (i.e., Kondo insulator). Moreover, we show that the Wilson ratio takes a value around 1 in the metallic system, in good agreement with experiments.

description: Can physical concepts and laws emerge in a neural network as it learns to predict the observation data of physical systems? As a benchmark and a proof-of-principle study of this possibility, here we show an introspective learning architecture that can automatically develop the concept of the quantum wave function and discover the Schrödinger equation from simulated experimental data of the potential-to-density mappings of a quantum particle. This introspective learning architecture contains a machine translator to perform the potential to density mapping, and a knowledge distiller auto-encoder to extract the essential information and its update law from the hidden states of the translator, which turns out to be the quantum wave function and the Schrödinger equation. We envision that our introspective learning architecture can enable machine learning to discover new physics in the future.

description: Mortality rates peaked early in the COVID-19 pandemic and then declined. Possible explanations are pharmacological and non-pharmacological treatments, vaccines and changing demographics. We sought to evaluate temporal trends in clinical characteristics and survival of patients hospitalised with COVID-19 during the first two years of the pandemic in Denmark. In this observational study, we included all adults with COVID-19 consecutively admitted to three hospitals in Copenhagen, Denmark, from March 2020 through March 2022. The primary outcome was overall survival up to day 90 from admission. We used multivariable Cox proportional hazards models to estimate the association of survival within five consecutive time-periods, based on admission date, adjusted for baseline characteristics, vaccination status, remdesivir and dexamethasone treatment. In 1630 included patients, the median age [IQR] was 68 [52, 79] years, 56.6% were men and 86.2% had comorbidity. Clinical characteristics changed over time. The crude 90-day mortality rate peaked in March–June 2020 with 28.9%, decreased from July 2020 to 17.5%, and increased again in January-March 2022 to 28.6%. Lower hazard ratios for death were observed in individuals admitted from July 2020 and persisted after adjusting for baseline characteristics. Adjusting for vaccination, remdesivir treatment and dexamethasone treatment attenuated the association in patients requiring low-flow oxygen. Our study suggests lower hazard rates for mortality in patients hospitalised with COVID-19 from July 2020 compared to March-June 2020, mainly driven by lower mortality in patients with a need of oxygen at baseline.

A comparison of university performance scores and ranks by MNCS and FSS

Year: 2018

description: In a previous article of ours, we explained the reasons why the MNCS and all similar per-publication citation indicators should not be used to measure research performance, whereas efficiency indicators (output to input) such as the FSS are valid indicators of performance. The problem frequently indicated in measuring efficiency indicators lies in the availability of input data. If we accept that such data are inaccessible, and instead resort to per-publication citation indicators, the question arises as to what extent institution performance rankings by MNCS are different from those by FSS (and so what effects such results could have on policy-makers, managers and other users of the rankings). Contrasting the 2008-2012 performance by MNCS and FSS of Italian universities in the Sciences, we try to answer that question at field, discipline, and overall university level. We present the descriptive statistics of the shifts in rank, and the correlations of both scores and ranks. The analysis reveals strong correlations in many fields but weak correlations in others. The extent of rank shifts is never negligible: a number of universities shift from top to non-top quartile ranks.
Substrate Sensitivity of the Adhesion and Material Properties of RF-Pecvd Amorphous Carbon

description: Hydrogenated amorphous carbon (a-C:H), deposited by the rf-plasma enhanced chemical vapour deposition (rf-PECVD) technique, is a promising material for large area electronic and interlayer dielectric applications. The structural and electronic properties of rf-PECVD a-C:H, deposited at room temperature from CH4/He and CH4/Ar gas mixtures, are shown to be sensitive to the substrate on which the thin film is deposited. The choice of substrate (c-Si or C7059 glass), and the existence and geometrical dimensions of any metallic pattern on the substrate surface, can result in significant spatial variations in the a-C:H adhesion and material properties. The observed effects are attributed to potential variations across the metal patterned substrates which influence the 'local' dc self-bias. This leads to spatial variations in the growth conditions and hence material properties. For electronic device and dielectric isolation applications this effect can result in significant variations in operating performance. The nature of the substrate and any overlying metallisation pattern are therefore important considerations.

description: Human papillomavirus (HPV) infection contributes to approximately 5% of the worldwide cancer burden. The three-dose HPV vaccine has demonstrated immunogenicity and efficacy. Humoral responses may be critical for preventing, controlling, and/or eliminating HPV infection. Using data from the HITCH cohort, we analysed humoral immune response to HPV vaccination among women in relation to the phylogenetic relatedness of HPV genotypes. We included 96 women aged 18–24 years attending college or university in Montreal, Canada. Participants provided blood samples at enrolment and five follow-up visits. Antibody response to bacterially expressed L1 and E6 glutathione S‐transferase fusion proteins of multiple Alphapapillomavirus types, and to virus-like particles (VLP-L1) of HPV16 and HPV18 were measured using multiplex serology. We assessed correlations between antibody seroreactivities using Pearson correlations (r). At enrolment, 87.7% of participants were unvaccinated, 2.4% had received one, 3.2% two, and 6.7% three doses of HPV vaccine. The corresponding L1 seropositivity to any HPV was 41.2%, 83.3%, 100%, and 97.0%. Between-type correlations for L1 seroreactivities increased with the number of vaccine doses, from one to three. Among the latter, the strongest correlations were observed for HPV58–HPV33 (Pearson correlation [r] = 0.96; α9-species); HPV11–HPV6 (r = 0.96; α10-species); HPV45–HPV18 (r = 0.95; α7-species), and HPV68–HPV59 (r = 0.95; α7-species). Correlations between HPV-specific antibody seroreactivities are affected by phylogenetic relatedness, with anti-L1 correlations becoming stronger with the number of vaccine doses received.

We use the method of averaging in Clifford's geometric algebra previously proposed by the author. We present explicit formulas for elements of spin group that correspond to the elements of orthogonal groups as two-sheeted covering. These formulas allow us to compute rotors, which connect two different frames related by a rotation in geometric algebra of arbitrary dimension.

description: Introduction: Fentanyl derivatives like cyclopropylfentanyl have recently appeared on the recreational drug market. Cyclopropylfentanyl is probably a highly potent opioid, but human toxicological data are not available so far. Similar to other fentanyl derivatives the most serious acute health risk due to the use of cyclopropylfentanyl is likely to be respiratory depression. In case of overdose, this may lead to apnoea, respiratory arrest and death. In this paper, we present three cases of severe intoxication with cyclopropylfentanyl. Methods: Observational case series including three intoxications treated in the Emergency Department at the University Medical Centre in 2017. In all cases, the consumption of any drugs was denied by the patients and relatives. Toxicological analyses using GC-MS, LC-QTOF-MS and LC-MS-MS of serum, urine samples and in one case of a powder sample, found in the hospital room, were performed. Medical records were reviewed to obtain clinical data. Results: Clinical effects of severe opioid intoxications comprising loss of consciousness, bradypnea, hypercapnia, arterial hypotension and miosis were recorded. In all cases, the novel fentanyl analogue cyclopropylfentanyl was detected in body fluids. In two cases further synthetic opioids (U-47700, methoxyacetylfentanyl, butyrfentanyl, 2-fluoroiso- or 4-fluoroisobutyrfentanyl) and mitragynine or desoxypipradrol were found. A discovered powder sample contained cyclopropylfentanyl, cyclopropylnorfentanyl, acetylfentanyl, 4-ANPP, U-47700 and caffeine. Except for acetylfentanyl all ingredients could be detected in the respective blood and urine sample. In two cases a cyclopropylfentanyl serum concentration of 51 and 76 ng/ml was determined. Discussion: In three cases of severe potentially life-threatening intoxication, cyclopropylfentanyl was verified using different analytical procedures. The ingested substance, as well as the excreted metabolites, were detected by application of various mass spectrometric techniques. Conclusions: In cases of intoxication without a medical history, the detailed toxicological analysis may reveal new psychoactive substances which are not detected by standard toxicological screening approaches. The high pharmacological potency of new products with unknown toxicological data and unknown synergistic effects may easily lead to a life-threatening overdose.

They are given by a functor from a category of colored and oriented graphs embedded into a 3-space to a category of representations of the quasi-triangular ribbon Hopf algebra $U_q(sl(2,\bf C))$. Coefficients in expansions of them with respect to $x$ ($q=e^x$) are known as the Vassiliev invariants of finite type. In the present paper, we construct two types of tangle operators of vertices. One of them corresponds to a Casimir operator insertion at a transverse double point of Wilson loops. This paper proposes a non-perturbative generalization of Kauffman's recent result based on a perturbative analysis of the Chern-Simons quantum field theory. As a result, a quantum group analog of Penrose's spin network is established taking into account of the orientation. We also deal with the 4-dimensional canonical quantum gravity of Ashtekar. It is verified that the graph invariants of Vassiliev type are compatible with constraints of the quantum gravity in the loop space representation of Rovelli and Smolin.

description: In this paper, the challenge of identifying high-value applications of quantum computing is examined. Although quantum computing holds enormous potential, it requires significant investments and development efforts. Therefore, it is crucial to define precise applications that can guide its development for an efficient industrialization process. To accomplish this goal, a methodology that systematically identifies and evaluates potential applications of quantum is developed. The methodology is designed for a strong alignment between tasks and technology, identification of problem and solution types, a systematic process for identifying problems, and a focus on socioeconomic challenges. It is structured according to the TRIZ methodology and comprises five submodels to determine socioeconomic applications for quantum computing.

description: Spatially splitting nonclassical light beams is in principle prohibited due to noise contamination during beam splitting. We propose a platform based on thermal motion of atoms to realize spatial multiplexing of squeezed light. Light channels of separate spatial modes in an anti-relaxation coated vapor cell share the same long-lived atomic coherence jointly created by all channels through the coherent diffusion of atoms which in turn enhances individual channel's nonlinear process responsible for light squeezing. Consequently, it behaves as squeezed light in one optical channel transferring to other distant channels even with laser powers below the threshold for squeezed light generation. An array of squeezed light beams was created with low laser power $\sim\text{mW}$. This approach holds great promise for applications in multi-node quantum network and quantum enhanced technologies such as quantum imaging and sensing.

From rankings to funnel plots: the question of accounting for uncertainty when measuring university research performance

description: The work applies the funnel plot methodology to measure and visualize uncertainty in the research performance of Italian universities in the science disciplines. The performance assessment is carried out at both discipline and overall university level. The findings reveal that for most universities the citation-based indicator used gives insufficient statistical evidence to infer that their research productivity is inferior or superior to the average. This general observation is one that we could indeed expect in a higher education system that is essentially non-competitive. The question is whether the introduction of uncertainty in performance reporting, while technically sound, could weaken institutional motivation to work towards continuous improvement.

description: The frequency dependence of the imaginary part of the infrared conductivity is calculated for a superconductor. Sharp structure, characteristic of superconductivity with an order parameter with s-wave symmetry, appears in the BCS limit as a minimum at a frequency equal to twice the gap value. This structure scales with temperature but gets progressively smeared and shifted as impurity scattering is increased. The relationship between low frequency results and the zero frequency limit is investigated. Experimental results on $\BKBO$ are also presented. The low frequency imaginary part of the conductivity displays a minimum at $2Δ\approx 12$ meV, and provides unequivocal evidence of an s-wave superconducting order parameter. Strong coupling (Eliashberg) results show similar trends. Using this formulation we find that the electron-phonon coupling in $\BKBO$ must necessarily be small, with coupling constant $λ\approx 0.2$, in agreement with conclusions drawn from measurements of the real part of the conductivity. Thus $\BKBO$ is an s-wave superconductor that is not driven by the electron-phonon interaction.

description: In the framework of the QCD effective action the vertices of gluon emission in interaction of reggeons are studied in the limit of small longitudinal momenta of the emitted gluon. It is found that the vertices drastically simplify in this limit so that the gluon becomes emitted from a single reggeon coupled to the projectile and target via multireggeon vertices. Contribution from this kinematical region is studied for double and 2x2 elementary collisions inside the composite projectile and target.

description: We address the effects of disorder on the conducting properties of metal and semiconducting carbon nanotubes. Experimentally, the mean free path is found to be much larger in metallic tubes than in doped semiconducting tubes. We show that this result can be understood theoretically if the disorder potential is long-ranged. The effects of a pseudospin index that describes the internal sublattice structure of the states lead to a suppression of scattering in metallic tubes, but not in semiconducting tubes. This conclusion is supported by tight-binding calculations.

description: We consider one parameter families of vector fields introduced by Rovella, obtained through modifying the eigenvalues of the geometric Lorenz attractor, replacing the expanding condition on the eigenvalues of the singularity by a contracting one. We show that there is no statistical stability within the set of parameters for which there is a physical measure supported on the attractor. This is achieved obtaining a similar conclusion at the level of the corresponding one-dimensional contracting Lorenz maps.

description: We analyze the effect of polydispersity in the arm number on the effective interactions, structural correlations and the phase behavior of star polymers in a good solvent. The effective interaction potential between two star polymers with different arm numbers is derived using scaling theory. The resulting expression is tested against monomer-resolved molecular dynamics simulations. We find that the theoretical pair potential is in agreement with the simulation data in a much wider polydispersity range than other proposed potentials. We then use this pair potential as an input in a many-body theory to investigate polydispersity effects on the structural correlations and the phase diagram of dense star polymer solutions. In particular we find that a polydispersity of 10%, which is typical in experimental samples, does not significantly alter previous findings for the phase diagram of monodisperse solutions.

description: This article advances a clinical tool for assessing typical and atypical phonological development in children speaking standard Modern Greek or Hellenic (ISO 639.1, el). The proposed tool develops a comprehensive test that is archetypical of the standard idiom and of predominant dialectal variations and seeks to be readily available for logopedics and language researchers of child Greek anywhere. By utilising the constraint-based nonlinear theoretical framework, this Greek battery complements a larger study that utilises equivalent methodology in the evaluation of phonological acquisition of monolingual children with typical and protracted phonological development across several languages. As an example, the efficacy of the tool is tested by administering it to a monolingual Greek-speaking girl, aged 4;8, whose speech shows evidence of delay on different phonological levels when compared to known monolingual norms/data. The ultimate aim is a standardised test to help establish reliable quantitative norms/stages in child Greek development, as a benchmark for assessment and intervention of phonological delay and disorder.

description: The SoLid experiment has been designed to search for an oscillation pattern induced by a light sterile neutrino state, utilising the BR2 reactor of SCK$\bullet$CEN, in Belgium. The detector leverages a new hybrid technology, utilising two distinct scintillators in a cubic array, creating a highly segmented detector volume. A combination of 5 cm cubic polyvinyltoluene cells, with $^6$LiF:ZnS(Ag) sheets on two faces of each cube, facilitate reconstruction of the neutrino signals. % The polyvinyltoluene scintillator is used as an $\overlineν_e$ target for the inverse beta decay of ($\overlineν_e + p \rightarrow e^{+}+n$), with the $^6$LiF:ZnS(Ag) sheets used for associated neutron detection. Scintillation signals are read out by a network of wavelength shifting fibres connected to multipixel photon counters. Whilst the high granularity provides a powerful toolset to discriminate backgrounds; by itself the segmentation also represents a challenge in terms of homogeneity and calibration, for a consistent detector response. The search for this light sterile neutrino implies a sensitivity to distortions of around $\mathcal{O}$(10)\% in the energy spectrum of reactor $\overlineν_e$. Hence, a very good neutron detection efficiency, light yield and homogeneous detector response are critical for data validation. The minimal requirements for the SoLid physics program are a light yield and a neutron detection efficiency larger than 40 PA/MeV/cube and 50 \% respectively. In order to guarantee these minimal requirements, the collaboration developed a rigorous quality assurance process for all 12800 cubic cells of the detector. To carry out the quality assurance process, an automated calibration system called CALIPSO was designed and constructed.
