Presentamos los resultados del estudio técnico, iconográfico e iconológico del mosaico bícromo hallado en el yacimiento romano recientemente descubierto de El Forau de la Tuta (en Artieda, Zaragoza, enclave localizado en el Prepirineo aragonés, concretamente en la conocida como Canal de Berdún), y encuadrado cronológicamente entre finales del s. I y principios del s. II d. C. Este pavimento cuenta con una serie de particularidades que le confieren un carácter especial: su extraordinario estado de conservación, su diseño basado en una bicromía invertida con figuras diseñadas con teselas blancas sobre un fondo realizado con teselas negras y la propia iconografía, con dos amores afrontados sobre hipocampos, delfines y veneras. Estas figuras y elementos son propios de un thíasos marino, una iconografía muy popular en ambientes termales o lugares vinculados con el agua. La estancia que decoró ha sido interpretada por varias razones, tales como las propias características del mosaico además de la presencia de un bocel hidráulico y de otras soluciones aislantes de la humedad, como el uestibulum de un edificio termal de grandes dimensiones del que solo conocemos una mínima parte, ya que está siendo actualmente objeto de excavación. Para su registro y documentación se han utilizado diversas técnicas geomáticas de fotogrametría aérea, terrestre y de láser escáner 3D, metodología que ha permitido continuar con el estudio de las estructuras exhumadas a pesar de que, por motivos de conservación, se hayan tenido que volver a cubrir. El yacimiento, además, cuenta con una segunda ocupación altomedieval, conocida gracias a los materiales exhumados y también por la presencia de un silo en el mosaico que aquí analizamos.

Published: February 2024

El municipio de Rabanales de Aliste, localizado al noroeste de la provincia de Zamora, acoge un buen número de inscripciones, principalmente estelas funerarias, que han sido objeto de estudio desde comienzos del siglo XX por diferentes investigadores. Aunque muchas de ellas han sido reutilizadas con posterioridad en paredes de casas o en la iglesia del municipio, las recientes excavaciones arqueológicas apuntan a su posible vinculación con el yacimiento de El Castrico, ocupado durante la segunda mitad del siglo I d. C. y la primera del II d. C. En este trabajo se analiza una estela funeraria inédita descubierta en 2021 empotrada en el interior de la iglesia de El Salvador, concretamente en el acceso a la base del campanario desde la nave central, que servía como sillar del dintel del vano de la puerta. Gracias al uso de técnicas novedosas como la fotogrametría digital y aplicación de análisis con SIG se ha podido leer correctamente la inscripción y descartar de la lectura algunas marcas, provocadas por las sucesivas alteraciones del bloque tras su reutilización. De esta manera, podemos minimizar el riesgo de interpretar erróneamente caracteres inexistentes en la pieza. A pesar de tratarse de una inscripción sencilla de tipo funerario, su análisis ha permitido dar a conocer la primera atestiguación del antropónimo Caraucus en el Imperio, de clara tradición celta, así como una posible relación de parentesco del tipo abuelo-padre-hijo, pudiendo completar la ascendencia familiar de otro personaje mencionado en el corpus epigráfico de Rabanales: Potitus, hijo de Alionus y nieto de Caraucus.
To rule-in, or not to falsely rule-out, that is the question: evaluation of hs-cTnT EQA performance in light of the ESC-2020 guideline

Abstract

Objectives
To accurately evaluate non-ST-elevated acute cardiac syndrome (NSTE-ACS), the quality of high-sensitive cardiac troponin (hs-cTn) assays is of vital importance. The 2020 revision of the NSTE-ACS guideline includes clinical decision-limits (CDL’s) to both rule-in and rule-out NSTE-ACS for most commercially available platforms, providing both 0/1 h and 0/2 h delta limits. Our study evaluated whether laboratories are able to meet the analytical performance specifications for imprecision (APS) for hs-cTnT.

Methods
Results from external quality assurance (EQA) in commutable samples were used to evaluate the current and historic performance of analyzers. The performance of analyzers that either passed or failed to comply with 0/1 h-APS were used on a real-world dataset of first hs-cTnT-values to simulate 10.000 samples of t=0, t=1 and t=2 h values with multiple delta’s for all relevant CDL’s. We compared the simulated values to the input values to obtain the percentage of aberrant results simulated.

Results
The majority of analyzers complies with APS for rule-in in 2022 (0/1 h: 90.4 % and 0/2 h: 100 %), compliance for the 0/1 h rule-out is still far from optimal (0/1 h: 30.7 %, 0/2 h: 75.4 %), with improving compliance over the past years (rule-in p=<0.0001, rule-out p=0.011, χ2). Whilst 0/1 h-APS-passing analyzers have a minute risk to falsely rule-out patients whom should be ruled-in (0.0001 %), failing performance increases this risk to 2.1 % upon using 0/1 h CDL’s. Here, adopting 0/2 h CDL’s is favorable (0.01 %).

Conclusions
Laboratories that fail to meet hs-cTnT 0/1 h-APS should improve their performance to the required and achievable level. Until performance is reached clinics should adopt the 0/2 h CDL’s.
When bias becomes part of imprecision: how to use analytical performance specifications to determine acceptability of lot-lot variation and other sources of possibly unacceptable bias
Authors: Thelen Marc H.M. , van Schrojenstein Lantman Marith 
Published: February 2024

Abstract
ISO 15189 requires laboratories to estimate the uncertainty of their quantitative measurements and to maintain them within relevant performance specifications. Furthermore, it refers to ISO TS 20914 for instructions on how to estimate the uncertainty and what to take into consideration when communicating uncertainty of measurement with requesting clinicians. These instructions include the responsibility of laboratories to verify that bias is not larger than medically significant. If estimated to be larger than acceptable, such bias first needs to be eliminated or (temporarily) corrected for. In the latter case, the uncertainty of such correction becomes part of the estimation of the total measurement uncertainty. If small enough to be acceptable, bias becomes part of the long term within laboratory random variation. Sources of possible bias are (not limited to) changes in reagent or calibrator lot variation or calibration itself. In this paper we clarify how the rationale and mathematics from an EFLM WG ISO/A position paper on allowable between reagent lot variation can be applied to calculate whether bias can be accepted to become part of long-term imprecision. The central point of this rationale is to prevent the risk that requesting clinicians confuse changes in bias with changes in the steady state of their patients.
Spectral collocation method for convection-diffusion equation
Authors: Li Jin , Cheng Yongling 
Published: February 2024

Abstract
Spectral collocation method, named linear barycentric rational interpolation collocation method (LBRICM), for convection-diffusion (C-D) equation with constant coefficient is considered. We change the discrete linear equations into the matrix equation. Different from the classical methods to solve the C-D equation, we solve the C-D equation with the time variable and space variable obtained at the same time. Furthermore, the convergence rate of the C-D equation by LBRICM is proved. Numerical examples are presented to test our analysis.

Abstract
Copper oxide nanoparticles (CuO NPs) were synthesized using ayurvedic medicine septilin. The septilin-mediated CuO NPs were characterized using UV–Vis, fourier-transform infrared spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM), and transmission electron microscope (TEM). The average particle size of CuO NPs was 8 nm as evident from TEM. Minimum inhibitory concentration of CuO NPs against Escherichia coli, Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus (MRSA), and Candida albicans was found in the range of 1–2.5 mg·mL−1. CuO NPs dose-dependently decreased the biofilm formation from 0.0315 to 2 mg·mL−1, at the highest dose of 2 mg·mL−1 of CuO NPs; 92.91%, 79.84%, and 71.57% decrease in biofilm was observed for P. aeruginosa, MRSA, and C. albicans, respectively. Down-regulation of biofilm upon treatment with nanoparticles (NPs) was also observed by SEM analysis. SEM analysis also showed the change in morphological structure, and deformities in bacterial and fungal cells upon treatment of NPs. Furthermore, the anticancer efficacy of NPs was assessed using colon cancer (HCT-116). The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay clearly showed the anticancer potential of NPs, as the concentration of CuO NPs increased, the number of viable cells decreased. The produced CuO NPs have promise for future investigations in many biological and therapeutic domains, including the treatment of microbial biofilm infections, as well as the inhibition of cancer cell growth.
Doubly weighted M-estimation for nonrandom assignment and missing outcomes
Authors: Negi Akanksha 
Published: February 2024

Abstract
This article proposes a class of M-estimators that double weight for the joint problems of nonrandom treatment assignment and missing outcomes. Identification of the main parameter of interest is achieved under unconfoundedness and missing at random assumptions with respect to the treatment and sample selection problems, respectively. Given the parametric framework, the asymptotic theory of the proposed estimator is outlined in two parts: first, when the parameter solves an unconditional problem, and second, when it solves a stronger conditional problem. The two parts help to summarize the misspecification scenarios permissible under the given framework and the role played by double weighting in each. As illustrative examples, the article also discusses the estimation of causal parameters like average and quantile treatment effects. With respect to the average treatment effect, this article shows that the proposed estimator is doubly robust. Finally, a detailed application to Calónico and Smith’s (The women of the national supported work demonstration. J Labor Econom. 2017;35(S1):S65–S97.) reconstructed sample from the National Supported Work training program is used to demonstrate the estimator’s performance in empirical settings.

Dimensions of Global Justice in Taxing Multinationals
Authors: Dietsch Peter , Rixen Thomas 
Published: February 2024

Abstract
Widespread tax evasion and avoidance have recently led to both significant reforms of international tax governance and increased attention from theorists of global tax justice. Against the background of an analysis of the double challenge of effectiveness and distribution facing the taxation of multinational enterprises, this paper puts forward a taxonomy of recent contributions of the tax justice literature. This taxonomy not only opens up an original angle of interpretation on global tax justice, but also provides a vantage point from which to evaluate recent reforms by the Organisation for Economic Co-operation and Development.

Published: February 2024

Abstract
The resource utilization of fly ash has always been a popular topic in the field of solid waste recycling. This paper is based on the three-phase reaction system of “fly ash (s)-[Ca(OH)2–H2O/ethanol] (l)-CO2 (g)”, using the bubble carbonization method to carry out heterogeneous phase reaction with fly ash as the core crystallized to form a fly ash-based calcium carbonate composite with higher brightness. The composite material is used in the filling of paper instead of calcium carbonate filler. Based on the previous research of our team, we focused on exploring the addition of miscible wettability additives (ethanol and acetone) to improve the wettability of the reaction system, thereby improving the whitening and modification effect of fly ash. The results showed that the addition of ethanol and acetone can significantly improve the coating effect of fly ash, however, acetone is slightly toxic, more volatile, and expensive than ethanol, so ethanol is more suitable as a wetting agent to be added to the reaction system. Under the optimal coating conditions, when the ratio of ethanol and water is 1:1, the brightness of fly ash can reach 71.62 % ISO, which is 17.29 % ISO higher than that without ethanol.

Abstract
Recently, the fabrication of a scaffold from biomaterials has been increased due to the lack of adequate natural bone for grafting. In this study, hydroxyapatite-chitosan-alginate-polyamide (HCAP) synthetic scaffold was fabricated using the thermally induced phase separation (TIPS) technique. The scaffold was cross-linked with either a chemical cross-linker (calcium chloride, 2-hydroxyethyl methacrylate (HEMA), or glutaraldehyde (GTA)) or a physical cross-linker (gamma irradiation (IR)) resulting in scaffolds HCAP-CaCl2, HCAP-HEMA, HCAP-GTA, and HCAP-IR, respectively. The cross-linked scaffolds were characterized based on physicochemical properties, cytotoxicity, and biocompatibility. HCAP-GTA showed the highest density and the lowest swelling ratio and biodegradation rate closely matching with those of the HCAP-IR. Porosity and density of the HCAP, HCAP-IR, and HCAP-GTA scaffolds were 92.14, 87.26, and 83.33 %, and 0.241, 0.307, and 0.335 g/cm3, respectively. The swelling ratio for the same scaffolds was 149, 110, and 108 % after 72 h of observation. Brine shrimp cytotoxicity and RBC biocompatibility assay confirmed the non-toxic nature of HCAP-IR and HCAP-GTA scaffolds. The HCAP-IR scaffold was tested for bone regeneration in the rabbit mandible defect model. Histological analysis revealed the regeneration of new bone and restoration of bone defect at the site of injury. These findings indicate that radiation induced physically cross-linked HCAP scaffold could be used as an alternative in bone defect replacement therapy.
Thrust-matching and optimization design of turbine-based combined cycle engine with trajectory optimization
Authors: Zhu JianFeng , Liu YingChen , Luo WenGuo , Guo Feng 
Published: February 2024

Abstract
Based on the trajectory optimization method of the Gauss pseudospectral, an aircraft/engine matching method is established for the turbine-based combined cycle (TBCC) engine. For a horizontal-takeoff hypersonic aircraft designed at Mach 5, a thrust-matching analysis of the TBCC engine is performed, and a rocket is integrated for further optimization design. The results show that the aircraft for boost missions should adopt the TBCC thrust with a takeoff thrust-to-weight ratio of 99.8 % to reduce the acceleration time and fuel consumption. In contrast, due to the low thrust-to-weight ratio of the TBCC engine, a high-thrust TBCC increases the inert weight in the cruise phase. Therefore, the aircraft designed for cruise missions should adopt the takeoff thrust-to-weight ratio of 92.0 %. Introducing a rocket whose maximum thrust is 10 % of the takeoff weight could assist the aircraft in overcoming the problem of the “thrust pinch” during the transonic and mode transition. With the assistance of rockets, the optimal takeoff thrust-to-weight ratio is 65.3 % for cruise aircraft, and the cruise range is increased by 18 %. While for the boost aircraft, adopting an optimal TBCC of 86.8 % takeoff thrust-to-weight ratio, the introduced rocket could reduce the fuel consumption and the TBCC engine weight by 4 %.
Getting the facts right: focus on adverbial verum marking in German
Authors: Müller Kalle 
Published: February 2024

Abstract
Two types of analyses of verum can be distinguished: either it is decomposed into focus and a focused verum element or it is a single, non-decomposable specialized lexical element which operates on discourse conditions. This paper argues for the former by investigating adverbs like tatsächlich, echt, wirklich in German that overtly realize a truth related predicate by illustrating the parallel between verb-verum and these adverbs for which their lexical contribution and the contribution of focus can be distinguished. It is shown, however, that this predicate does not encode polarity but factuality, which is analyzed in terms of a modal object. The syntactic location is determined to be between polarity and speaker-oriented categories. Other effects regarding commitment and evidentiality come as a by-product of highlighting factuality.
The crystal structures and magnetic properties of YbMg0.75In1.25 and Yb6Mg6.41In5.59
Authors: Reimann Maximilian Kai , Pöttgen Rainer 
Published: February 2024

Abstract
The quasi-binary system YbMg2-YbIn2 was studied around the equiatomic composition. In contrast to the ordered rare earth (RE) phases REMgIn (ZrNiAl type), ytterbium forms phases with different structures and pronounced Mg/In mixing (M sites). The structures of YbMg0.75In1.25 (CaLiSn type, P3m1, a = 501.95(7), c = 1087.3(2) pm, wR2 = 0.0490, 790 F
2 values, 32 variables) and Yb6Mg6.41In5.59 (Yb6Ir5Ga7 type, P63/mcm, a = 1060.77(14), c = 970.27(16) pm, wR2 = 0.0484, 701 F
2 values, 26 variables) were refined from single-crystal X-ray diffractometer data. YbMg0.75In1.25 is an AlB2 superstructure with a tripling of the subcell. The magnesium and indium atoms form three differently puckered layers of M
6 hexagons. The Yb6Mg6.41In5.59 structure is derived from the hexagonal Laves phase YbMg2 (MgZn2 type, P63/mmc). A klassengleiche symmetry reduction leads to four crystallographically independent M sites for the rows of corner- and face-sharing tetrahedra which allow a composition close to the equiatomic one. The M–M distances in both structures cover the broad range from 289 to 331 pm, comparable to the sums of the covalent radii. Temperature dependent magnetic susceptibility studies of the polycrystalline YbMg0.75In1.25 and Yb12Mg13In11 samples indicate Pauli paramagnetism with room temperature values of 2.8(1) × 10−3 emu mol−1 (YbMg0.75In1.25) and 5.2(1) × 10−3 emu mol−1 (Yb12Mg13In11).
