Two examples of anthropic manipulation and postmortem processing of human remains at megalithic sites in inland Iberia: La Cabaña and Los Zumacales (Spanish northern sub‐plateau)
Authors: Santa‐Cruz Angélica , Velasco‐Vázquez Javier 
Published: December 2023

AbstractSeveral recent studies have demonstrated the complexity of funerary practices in megalithic burials. Mortuary taphonomy has proposed models to explain these practices, in which different actions, such as the generation of primary and secondary deposits, the selection and manipulation of bone remains, the extraction of materials from the grave, and so forth, can be identified. However, in the northern sub‐plateau of the Iberian Peninsula, the interpretation of funerary gestures related to megalithic tombs has not been systematically studied from the perspective of taphonomy. In this paper, we study two sites, Los Zumacales and La Lora, dated to the fourth millennium B.C. The analysis considers all the burial practices linked with megalithic tombs, with a focus on the social and natural processes involved in the formation of these complex mortuary deposits. In both examples, direct evidence of perimortem manipulation of human remains is documented by the presence of fresh fractures and cut marks in different long bones. As suggested in the discussion, this evidence may be related to secondary reduction practices following the initial deposition of the bodies.

AbstractObjectiveTo assess placement outcomes using a levonorgestrel 52 mg intrauterine device (IUD) inserter designed for single‐handed use.MethodsInvestigators enroled participants 18–45 years to have the IUD inserted using a redesigned inserter with removal 5–15 min after placement. Physicians and participants provided feedback on their insertion experience.ResultsSuccessful placement occurred in 48 of 50 (96.0%) enroled participants. Investigators rated insertion device loading “easy” in 49 (98.0%) and placement “easy” in 44 (88.0%) cases. Cramping pain was reported at insertion by 47 (94.0%) participants, mostly mild (32 [64.0%]) or moderate (11 [22.0%]).ConclusionThe single‐handed inserter is easy to use and results in high rates of insertion success.

Published: December 2023

AbstractWith rapidly increasing demand for high energy density, silicon (Si) is greatly expected to play an important role as the anode material of lithium‐ion batteries (LIBs) due to its high specific capacity. However, large volume expansion for silicon during the charging process is still a serious problem influencing its cycling stability. Here, a Si/C composite of vertical graphene sheets/silicon/carbon/graphite (VGSs@Si/C/G) is reported to address the electrochemical stability issues of Si/graphite anodes, which is prepared by adhering Si nanoparticles on graphite particles with chitosan and then in situ growing VGSs by thermal chemical vapor deposition. As a promising anode material, due to the buffering effect of VGSs and tight bonding between Si and graphite particles, the composite delivers a high reversible capacity of 782.2 mAh g−1 after 1000 cycles with an initial coulombic efficiency of 87.2%. Furthermore, the VGSs@Si/C/G shows a diffusion coefficient of two orders higher than that without growing the VGSs. The full battery using VGSs@Si/C/G anode and LiNi0.8Co0.1Mn0.1O2 cathode achieves a high gravimetric energy density of 343.6 Wh kg−1, a high capacity retention of 91.5% after 500 cycles and an excellent average CE of 99.9%.

AbstractStructure engineering of magnetic‐dielectric multi‐components is emerging as an effective approach for presuming high‐performance electromagnetic (EM) absorption, but still faces bottlenecks due to the ambiguous regulation mechanism of surface morphology. Here, a novel wrinkled surface structure is tailored on the ZnFe2O4 microsphere via a spray‐pyrolysis induced Kirkendall diffusion effect, the conductivity of the sample is affected, and a better impedance matching is adjusted by modulating the concentration of metal nitrate precursors. Driven by a vapor phase polymerization, conductive polypyrrole (PPy) shell are in situ decorated on the ZnFe2O4 microsphere surfaces, ingeniously constructing a core‐shell ZnFe2O4@PPy composites. Moreover, a systematic investigation reveals that this unique wrinkled surface structure is highly dependent on the metal salt concentration. Optimized wrinkle ZnFe2O4@PPy composite exhibits a minimum reflection loss (RLmin) reached −41.0 dB and the effective absorption bandwidth (EAB) can cover as wide as 4.1 GHz. The enhanced interfacial polarization originated from high‐density ZnFe2O4‐PPy heterostructure, and the conduction loss of PPy contributes to the boosted dielectric loss capability. This study gives a significant guidance for preparing high‐performance EM composites by tailoring the surface wrinkle structure.

AbstractHierarchical self‐assembly of 2D metal‒organic layers (MOLs) for the construction of advanced functional materials have witnessed considerable interest, due to the increasing atomic utilizations and well‐defined atom‒property relationship. However, the construction of atomically precise MOLs with mono‐/few‐layered thickness through hierarchical self‐assembly process remains a challenge, mostly because the elaborate long‐range order is difficult to control via conventional noncovalent interaction. Herein, a quadruple π‐sticked metal‒organic layer (πMOL) is reported with checkerboard‐like lattice in ≈1.0 nanometre thickness, on which the catalytic selectivity can be manipulated for highly efficient CO2 reduction reaction (CO2RR) and hydrogen evolution reaction (HER) over a single metal site. In saturated CO2 aqueous acetonitrile, Fe‐πMOL achieves a highly effective CO2RR with the yield of ≈3.98 mmol g‒1 h‒1 and 91.7% selectivity. In contrast, the isostructural Co‐πMOL as well as mixed metallic FeCo‐πMOL exhibits a high activity toward HER under similar conditions. DFT calculations reveal that single metal site exhibits the significant difference in CO2 adsorption energy and activation barrier, which triggers highly selective CO2RR for Fe site and HER for Co site, respectively. This work highlights the potential of supramolecular π…π interaction for constructing monolayer MOL materials to uniformly distribute the single metal sites for artificial photosynthesis.

Published: December 2023

AbstractHepatitis D virus was first described by Mario Rizzeto in 1977, and it is considered chronic viral hepatitis with the poorest prognosis. Despite its discovery almost 50 years ago, progress in its diagnosis and treatment has been scarce until recent years. The approval of bulevirtide has shed some light for patients with Chronic Hepatitis D, although important gaps regarding its use in therapy as well as about the epidemiology and diagnosis of the disease need to be addressed.
Introductory Overview: Institutionalizing Inclusion, Sustainability and Resilience in Market Economies
Authors: Samans Richard 
Published: December 2023

AbstractThis chapter argues that the root of the increasingly serious crisis facing capitalism and liberalism more generally can be located in a fundamental distortion in the way its canon of economic principles and tools have evolved since the eighteenth and nineteenth centuries, and especially in the way they have been applied over the past several decades. In effect, generations of economists and policymakers have been trained to behave as if Adam Smith's “invisible hand” of market-based resource allocation can be relied upon to optimize not only the wealth of nations (its core function as stated by Smith) but also the well-being of their populations at large. A rising tide of GDP, as it were, ultimately lifts all boats. But Smith and other important pioneers of the field assumed no such thing. They believed that market-oriented measures to increase the production and wealth of nations were a necessary but by no means sufficient condition for raising the broad standard of living of their people. A range of institutions—legal and other norms, policy incentives and administrative capacities mainly but not only in the public sector—were required to ensure appropriate levels of social inclusion, environmental sustainability and human and systemic resilience. Modern economics’ policy immobility and political tin ear in the face of these challenges is rooted in a certain indoctrinated incomprehension. Its implicit assumption that GDP growth eventually diffuses or “trickles down” into broad socioeconomic progress and security has never been properly recognized and interrogated. The essential principle the book posits is that the broad living standards of nations—the main facets of the median household’s material well-being—deserve as much direct policy attention and institutional cultivation by economists and policymakers as the wealth of nations, that is to say, national income or GDP.
From the Wealth to the Living Standards of Nations: Internalizing the Social Contract in Macroeconomic Theory and Policy
Authors: Samans Richard 
Published: December 2023

AbstractThis chapter proposes a reformulation and rebalancing of the standard liberal economic growth and development model by integrating key institutional dimensions of the social contract into the heart of macroeconomic theory. Specifically, it defines an extensive ecosystem of policy and institutional features that have an important bearing on the rate and breadth of progress in household living standards, categorizing them in five principal policy domains. These are represented as an economy’s “factors of distribution” and modelled as a system—an aggregate distribution function analogous to the aggregate production function. This model of the main channels by which rising living standards propagate in an economy is accompanied by a map of related domains of enabling policy and institutional strength. This policy and institutional ecosystem is the practical manifestation of a country’s social contract—how it translates its values with respect to inclusion, sustainability and resilience into the rules of the game within its economy. The aggregate distribution function is the de facto income distribution system or “living standards diffusion mechanism” of modern market economies. It is the combination and indeed interaction of the aggregate distribution and production functions of an economy that determine its progress in median household living standards. Macroeconomic theory and policy should be refocused on the goal of increasing the aggregate social welfare, or living standards, of nations rather than solely their GDP, or wealth, by placing equal and parallel emphasis on strengthening the aggregate production and distribution functions of economies. This is the golden rule of human-centred economics.
Human-Centred International Economic Policy: Institutionalizing Inclusion, Sustainability and Resilience in International Economic Governance and Cooperation
Authors: Samans Richard 
Published: December 2023

AbstractThis chapter presents an agenda for deep reform of international economic governance and cooperation based on the human-centred logic of placing the bottom-line measure of national economic progress, broad progress in living standards, rather than GDP growth at the heart of international macroeconomic policy cooperation; the international financial architecture; and international trade and technology governance. This twenty-first century renovation of the international economic architecture is based on a “Roosevelt Consensus” model of growth and development that emphasizes the social contract's crucial role in advancing inclusion, sustainability and resilience. Major reforms are proposed to IMF and World Bank macroeconomic policy analysis and advice, including debt sustainability methodology; and international development and climate finance, through the tripling of ODA-related external flows to more than 80 of the poorest countries in each of the next seven years, including for the purpose of retiring and replacing most of the world’s coal-fired power-generating capacity over the next 15 years while doubling global annual investment in renewable energy research and development. Additional proposals are made to rebalance international trade policy by coordinating trade, labour, climate change and development cooperation to a far greater extent through new types of international economic alliances, including one that could create a workable solution to the thorny issue of climate leakage, and giving the WTO a new lease on life facilitating discussions among plurilateral trade agreements and their members about how the best normative and facilitative features of such agreements could ultimately be knit together into a reconstituted, high-road multilateral trading system. Together, these reforms would greatly accelerate progress toward UN goals.

Does Hawking effect always degrade fidelity of quantum teleportation in Schwarzschild spacetime?
Authors: Wu Shu-Min , Fan Xiao-Wei , Wang Rui-Di , Wu Hao-Yu , Huang Xiao-Li , Zeng Hao-Sheng 
Published: December 2023

Abstract
Previous studies have shown that the Hawking effect always destroys quantum correlations and the fidelity of quantum teleportation in the Schwarzschild black hole. Here, we investigate the fidelity of quantum teleportation of Dirac fields between users in Schwarzschild spacetime. We find that, with the increase of the Hawking temperature, the fidelity of quantum teleportation can monotonically increase, monotonically decrease, or non-monotonically increase, depending on the choice of the initial state, which means that the Hawking effect can create net fidelity of quantum teleportation. This striking result banishes the extended belief that the Hawking effect of the black hole can only destroy the fidelity of quantum teleportation. We also find that quantum steering cannot fully guarantee the fidelity of quantum teleportation in Schwarzschild spacetime. This new unexpected source may provide a new idea for the experimental evidence of the Hawking effect.
Wheeler DeWitt states of a charged AdS4 black hole
Authors: Blacker Matthew J. , Ning Sirui 
Published: December 2023

Abstract
We solve the Wheeler DeWitt equation for the planar Reissner-Nordström-AdS black hole in a minisuperspace approximation. We construct semiclassical Wheeler DeWitt states from Gaussian wavepackets that are peaked on classical black hole interior solutions. By using the metric component gxx as a clock, these states are evolved through both the exterior and interior horizons. Close to the singularity, we show that quantum fluctuations in the wavepacket become important, and therefore the classicality of the minisuperspace approximation breaks down. Towards the AdS boundary, the Wheeler DeWitt states are used to recover the Lorentzian partition function of the dual theory living on this boundary. This partition function is specified by an energy and a charge. Finally, we show that the Wheeler DeWitt states know about the black hole thermodynamics, recovering the grand canonical thermodynamic potential after an appropriate averaging at the black hole horizon.
Monte Carlo study of Schwinger model without the sign problem
Authors: Ohata Hiroki 
Published: December 2023

Abstract
Monte Carlo study of the Schwinger model (quantum electrodynamics in one spatial dimension) with a topological θ term is very difficult due to the sign problem in the conventional lattice formulation. In this paper, we point out that this problem can be circumvented by utilizing the lattice formulation of the bosonized Schwinger model, initially invented by Bender et al. in 1985. After conducting a detailed review of their lattice formulation, we explicitly validate its correctness through detailed comparisons with analytical and previous numerical results at θ = 0. We also obtain the θ dependence of the chiral condensate and successfully reproduce the mass perturbation result for small fermion masses m/g ≲ 0.125. As an application, we perform a precise calculation of the string tension and quantitatively reveal the confining properties in the Schwigner model at finite temperature and θ region for the first time. In particular, we find that the string tension is negative for noninteger probe charges around θ = π at low temperatures.

All n-point tree-level scattering amplitudes for n ≥ 4 of this sector are found to vanish in the flat limit.

Visual complexity of urban streetscapes: human vs computer vision
Authors: Florio Pietro , Leduc Thomas , Sutter Yannick , Brémond Roland 
Published: December 2023

AbstractUnderstanding visual complexity of urban environments may improve urban design strategies and limit visual pollution due to advertising, road signage, telecommunication systems and machinery. This paper aims at quantifying visual complexity specifically in urban streetscapes, by submitting a collection of geo-referenced photographs to a group of more than 450 internet users. The average complexity ranking issued from this survey was compared with a set of computer vision predictions, attempting to find the optimal match. Overall, a computer vision indicator matching comprehensively the survey outcome did not clearly emerge from the analysis, but a set of perceptual hypotheses demonstrated that some categories of stimuli are more relevant. The results show how images with contrasting colour regions and sharp edges are more prone to drive the feeling of high complexity.
Potential of measured relative shifts in collision cross section values for biotransformation studies
Authors: Lanshoeft Christian , Schütz Raphael , Lozac’h Frédéric , Schlotterbeck Götz , Walles Markus 
Published: December 2023

AbstractIon mobility spectrometry–mass spectrometry (IMS-MS) separates gas phase ions due to differences in drift time from which reproducible and analyte-specific collision cross section (CCS) values can be derived. Internally conducted in vitro and in vivo metabolism (biotransformation) studies indicated repetitive shifts in measured CCS values (CCSmeas) between parent drugs and their metabolites. Hence, the purpose of the present article was (i) to investigate if such relative shifts in CCSmeas were biotransformation-specific and (ii) to highlight their potential benefits for biotransformation studies. First, mean CCSmeas values of 165 compounds were determined (up to n = 3) using a travelling wave IMS-MS device with nitrogen as drift gas (TWCCSN2, meas). Further comparison with their predicted values (TWCCSN2, pred, Waters CCSonDemand) resulted in a mean absolute error of 5.1%. Second, a reduced data set (n = 139) was utilized to create compound pairs (n = 86) covering eight common types of phase I and II biotransformations. Constant, discriminative, and almost non-overlapping relative shifts in mean TWCCSN2, meas were obtained for demethylation (− 6.5 ± 2.1 Å2), oxygenation (hydroxylation + 3.8 ± 1.4 Å2, N-oxidation + 3.4 ± 3.3 Å2), acetylation (+ 13.5 ± 1.9 Å2), sulfation (+ 17.9 ± 4.4 Å2), glucuronidation (N-linked: + 41.7 ± 7.5 Å2, O-linked: + 38.1 ± 8.9 Å2), and glutathione conjugation (+ 49.2 ± 13.2 Å2). Consequently, we propose to consider such relative shifts in TWCCSN2, meas (rather than absolute values) as well for metabolite assignment/confirmation complementing the conventional approach to associate changes in mass-to-charge (m/z) values between a parent drug and its metabolite(s). Moreover, the comparison of relative shifts in TWCCSN2, meas significantly simplifies the mapping of metabolites into metabolic pathways as demonstrated.
