This compact book offers a closely researched account of the early years of the Qajar dynasty and state, whose political development was permanently marked by the territorial struggle with the Russian Empire in the South Caucasus in its first three decades. Behrooz's work builds on Muriel Atkin's classic Russia and Iran 1780–1928 (1980), and although unlike Atkin he does not make use of any sources in Russian, the range of Persian-language material he draws upon is much greater, and the two books complement each other well. The first two chapters effectively set the political scene, providing a review of the circumstances of Aqa Muhammad Khan's rise to power, his struggle with the Zand rulers of Shiraz, and the extensive preparations he made to secure the succession of his nephew, Baba Khan Jahanbani, the future Fath Ali Shah. These bore fruit when Aqa Muhammad Shah was murdered by his own servants in Shusha in 1797. Significantly, this took place during a campaign to subdue Qarabagh. The central figure of the book, and of the wars against Russia, is Fath Ali's son Abbas Mirza, but a particular strength of Behrooz's account is his close understanding of the family and intertribal relationships among the Qajar elite, as well as of the petty dynasties that ruled in Qarabagh, Iravan, Badkubeh (Baku), and Derbent in this period.

We have conducted a widefield, wideband, snapshot survey using the Australian SKA Pathfinder (ASKAP) referred to as the Rapid ASKAP Continuum Survey (RACS). RACS covers ≈ 90% of the sky, with multiple observing epochs in three frequency bands sampling the ASKAP frequency range of 700–1 800 MHz. This paper describes the third major epoch at 1 655.5 MHz, RACS-high, and the subsequent imaging and catalogue data release. The RACS-high observations at 1 655.5MHz are otherwise similar to the previously released RACS-mid (at 1367.5 MHz), and were calibrated and imaged with minimal changes. From the 1 493 images covering the sky up to declination ≈ +48°, we present a catalogue of 2 677 509 radio sources. The catalogue is constructed from images with a median root-mean-square noise of ≈ 195 μJy PSF−1 (point-spread function) and a median angular resolution of 11″. 8 × 8″. 1. The overall reliability of the catalogue is estimated to be 99.18 %, and we find a decrease in reliability as angular resolution improves. We estimate the brightness scale to be accurate to 10 %, and the astrometric accuracy to be within ≈ 0″. 6 in right ascension and ≈ 0″. 7 in declination after correction of a systematic declination-dependent offset. All data products from RACS-high, including calibrated visibility datasets, images from individual observations, full-sensitivity mosaics, and the all-sky catalogue are available at the CSIRO ASKAP Science Data Archive.

This paper reports on the experiences of using an early assessment intervention, specifically employing a Use-Modify-Create scaffold, to teach first-year undergraduate functional programming. The particular intervention that was trialled was the use of an early assessment instrument, in which students had to use code given to them, or slightly modify it, to achieve certain goals. The intended outcome was that the students would thus engage earlier with the functional language, enabling them to be better prepared for the second piece of assessment, where they create code to solve given problems. This intervention showed promise: the difference between a student’s score on the Create assignment improved by an average of 9% in the year after the intervention was implemented, a small effect.

The generation of an autoresonantly phase-locked high-amplitude plasma waves to the chirped beat frequency of two driving lasers is studied in two dimensions using particle-in-cell simulations. The two-dimensional plasma and laser parameters correspond to those that optimized the plasma wave amplitude in one-dimensional simulations. Near the start of autoresonant locking, the two-dimensional simulations appear similar to one-dimensional particle-in-cell results (Luo et al., Phys. Rev. Res., vol. 6, 2024, p. 013338) with plasma wave amplitudes above the Rosenbluth–Liu limit. Later, just below wave breaking, the two-dimensional simulation exhibits a Weibel-like instability and eventually laser beam filamentation. These limit the coherence of the plasma oscillation after the peak plasma wave field is obtained. In spite of the reduction of spatial coherence of the accelerating density structure, the acceleration of self-injected electrons in the case studied remains at $70\,\%$ to $80\,\%$ of that observed in one dimension. Other effects such as plasma wave bowing are discussed.

The impact of the European Union (EU) in strengthening nanotechnology risk regulation in non-EU countries is still an under-researched topic. This article focuses on the EU’s influence on its trading partners, using the case study of Israel, which in 2023 adopted restrictions on nanotechnology in cosmetics products following the EU. It is argued that EU risk regulation have been both a trigger and a formative factor for the development of Israeli nanomaterials restrictions. The importance and economic interdependence in the EU market for cosmetics has prompted a response from Israeli policymakers. In addition, the EU regulatory capacity through its expertise and sanctioning authority have influenced the Israeli regulatory agenda. The article shows that the impact of EU regulation also coincided with domestic economic factors, concerns about technology policy and policymakers’ preference for stringent standards. Israel’s risk regulation of nanomaterials in cosmetics provides a useful case study for analyzing the EU’s regulatory impact on its trading partners. Once again, stricter EU’s health and safety regulation drives those of its trading partner upward.

The development of runic writing (the early Germanic alphabetic script) and the practice of inscribing runes on stone are difficult to trace, particularly as rune-stone inscriptions are rarely found in original and/or datable contexts. The discovery of several inscribed sandstone fragments at the grave field at Svingerud, Norway, with associated radiocarbon dates of 50 BC–AD 275, now provide the earliest known context for a runestone. An unusual mixture of runes and other markings are revealed as the fragments are reconstructed into a single standing stone, suggesting multiple episodes of inscription and providing insight into early runic writing practices in Iron Age Scandinavia.

In this paper, we define compact open subgroups of quasi-split even unitary groups for each even non-negative integer and establish the theory of local newforms for irreducible tempered generic representations with a certain condition on the central characters. To do this, we use the local Gan–Gross–Prasad conjecture, the local Rankin–Selberg integrals and the local theta correspondence.
