Looting and plough damage to the eighth–fifth centuries BC tumulus of Creney-le-Paradis, France, hinders interpretation of this potentially significant site. Nevertheless, application of novel microtomographic techniques in combination with optical and scanning electron microscopy allows the first detailed examination of 99 textile fragments recovered from the central pit. The authors argue that the diversity of textiles revealed—at least 16 different items—and the quality of weaving involved confirm earlier interpretations of the high status of this burial, which is comparable, at least in terms of textiles and metal urns, with other ‘aristocratic’ tombs of the European Iron Age.

The influence of man on man is exercised sometimes to assemble a group of individuals moved toward common action, sometimes to remedy the antagonisms which naturally result from the conflict of human wills. These two situations give rise to two forms of authority which are seldom found in the same person, since one form is essentially exciting and the other essentially calming. The contrast between them can be illustrated by the two images of the bridge of Arcole and the oak of Vincennes.

The print which shows Bonaparte hurling himself at the enemy and urging his soldiers to follow sums up in a single scene all the influence toward action he had exercised on them since he had taken command. He had found troops low in morale and without any disposition to take the offensive; he breathed his own fire into them; his famous proclamation tended to imbue them with his own ambition, and united them as participants in his plan. By a remarkable feat of transference, impatient because he was without glory, he made them realize that they were without shoes, and he materialized for them his own vast dreams in the visible form of “the fertile plains of Lombardy.”

Contemporary society is preoccupied with wealth. There is no need here to distinguish between capitalism and communism. It is a well-known fact that the great declared objective of Soviet economic planning is “to attain and to surpass the American standard of life.”

Every country employs statisticians to compute the annual increase in its national wealth. If the increase is substantial, the government prides itself on it; if it is small, the opposition finds in it a grievance capable of rallying public opinion behind it. In democratic countries, the political organizations that are most firmly entrenched are the ones that seek to advance the pretensions of one group for a larger share of the national wealth, and those that seek to defend the present share of a group against such pretensions. Public affairs consist to a large extent of pleadings and pressures concerning the division of wealth, and to some extent of more technical discussions concerning its increase.

Industry 4.0 deals with a digital revolution, integrating technologies like Virtual Reality, Augmented Reality, Digital Twin, and Robotics. This transformation unlocks opportunities in engineering, addressing sustainability challenges. Stakeholders use I4.0 technologies, including Industry 5.0, to measure sustainability indicators. This paper reviews I4.0 technologies for assessing sustainability, offering an SI framework in manufacturing and smart product design. Decision-makers can optimize environmental, social, and economic impacts in smart product design using this framework.

Offshore wind turbines intend to take a rapidly growing share in the electric mix. The design, installation, and exploitation of these industrial assets are regulated by international standards, providing generic guidelines. Constantly, new projects reach unexploited wind resources, pushing back installation limits. Therefore, turbines are increasingly subject to uncertain environmental conditions, making long-term investment decisions riskier (at the design or end-of-life stage). Fortunately, numerical models of wind turbines enable to perform accurate multi-physics simulations of such systems when interacting with their environment. The challenge is then to propagate the input environmental uncertainties through these models and to analyze the distribution of output variables of interest. Since each call of such a numerical model can be costly, the estimation of statistical output quantities of interest (e.g., the mean value, the variance) has to be done with a restricted number of simulations. To do so, the present paper uses the kernel herding method as a sampling technique to perform Bayesian quadrature and estimate the fatigue damage. It is known from the literature that this method guarantees fast and accurate convergence together with providing relevant properties regarding subsampling and parallelization. Here, one numerically strengthens this fact by applying it to a real use case of an offshore wind turbine operating in Teesside, UK. Numerical comparison with crude and quasi-Monte Carlo sampling demonstrates the benefits one can expect from such a method. Finally, a new Python package has been developed and documented to provide quick open access to this uncertainty propagation method.

In the Tertiary lacustrine sediments of the Jbel Rhassoul (Morocco), stevensite and sepiolite, confined to the dolomitic facies, are commonly mixed at lower parts of the so-called “Formation Intermédiaire”. Transmission electron microscopy (TEM) observations reveal a relation between these 2 magnesian clay minerals. One can observe the different transition steps, from the initial folded layers of stevensite to the fibers emerging from the layers, and finally to the complete replacement of stevensite by sepiolite. That transition can also be observed by scanning electron microscopy (SEM), where the fibers seem to grow at the expense of stevensite. Thermodynamic calculations have been applied to provide geochemical conditions for the formation of sepiolite after stevensite. Early deposition of the “Formation Intermédiaire” occurred under climatic conditions varying between dry and wet. During dry periods, the relative silica enrichment and the pH decrease in the lake water should destabilize stevensite, leading to the formation of sepiolite. Subsequently, a perennial wet climate would lead to the formation of pure stevensite without any trace of sepiolite.

On March 29, 2018, the Government of the Co-operative Republic of Guyana (hereinafter Guyana) filed in the Registry of the Court an application instituting proceedings against the Bolivarian Republic of Venezuela (hereinafter Venezuela) with respect to a dispute concerning “the legal validity and binding effect of the Award regarding the Boundary between the Colony of British Guiana and the United States of Venezuela, of 3 October 1899” (hereinafter the 1899 Award or the Award).

In this work, we introduce rental markets in a general equilibrium model with borrowing constraints and infinitely lived agents. We estimate our model using standard Bayesian methods and match US data on recent decades. We highlight a crucial relationship that strongly links interest rates, house prices, and rents. It represents agents’ arbitrage when choosing their degree of participation in the housing market (i.e. their real estate holdings). This framework is particularly well suited for explaining how policy-induced changes in households’ preferences have driven house prices up while pushing rent-price ratios down in the aftermath of the Covid-19 outbreak. It also allows us to parsimoniously track the unequal impact of these changes on agents’ decisions and welfare, which crucially depends on whether they are owners or renters.

Starting from loop equations, we prove that the wave functions constructed from topological recursion on families of degree $2$ spectral curves with a global involution satisfy a system of partial differential equations, whose equations can be seen as quantizations of the original spectral curves. The families of spectral curves can be parametrized with the so-called times, defined as periods on second type cycles, and with the poles. These equations can be used to prove that the WKB solution of many isomonodromic systems coincides with the topological recursion wave function, which proves that the topological recursion wave function is annihilated by a quantum curve. This recovers many known quantum curves for genus zero spectral curves and generalizes this construction to hyperelliptic curves.

The current regulatory framework for Electrical and Electronic Equipment (EEE) is changing and now requires manufacturers to disclose the environmental performance of their products. This means that manufacturers must perform a life cycle analysis (LCA) on their entire range of products. An LCA is a recognized and standardized methodology for assessing the environmental impact of activities. However, communicating this information to consumers is challenging because it can be complicated.

Despite this challenge, there is currently no common standard for communicating environmental information to consumers. The objective of this study is to explore the best practices for conveying environmental information. To achive this, a review of current environmental labeling approaches and recommendations available in the literature is conducted. Additionally, consumer requirements are collected and analyzed through a questionnaire that employs both quantitative and qualitative methods. The information collected is then used to develop the best practices for implementing environmental labeling for EEE.

We formalize the concepts of holomorphic affine and projective structures along the leaves of holomorphic foliations by curves on complex manifolds. We show that many foliations admit such structures, we provide local normal forms for them at singular points of the foliation, and we prove some index formulae in the case where the ambient manifold is compact. As a consequence of these, we establish that a regular foliation of general type on a compact algebraic manifold of even dimension does not admit a foliated projective structure. Finally, we classify foliated affine and projective structures along regular foliations on compact complex surfaces.

Short-channel Gallium Nitride (GaN) high-electron-mobility transistors (HEMTs) often utilize T-shape gates due to their large gate-line cross-sectional area and subsequent fMAX increase. In this paper, we report the linearity trade-offs associated with varying the T-gate geometries of AlGaN/GaN HEMTs on Si, specifically the gate extensions which serve as field plates and their impact on the large-signal performance. Small-signal characterization and modeling, in addition to TCAD, provide initial guidelines for the optimal dimensions for the gate field plates using the ratio of fT and the product of the gate resistance and the gate-to-drain capacitance. We utilize various characterization methods, including 6 GHz non-linear vector network analyzer characterization in addition to load-pull, to quantify the amplitude and phase distortion and their subsequent impact on the large-signal metrics of the devices under differing matching conditions and bias points. We deduce that the influence of the gate field plates on the amplitude and phase distortion is non-negligible, particularly under matched conditions.
