With the development of GNSS (Global Navigation Satellite System), LEO (Low Earth Orbit) systems are adopted to enhance the system performance of GNSS. The signal Doppler of the LEO satellite is seven to nine times that of GNSS signals, which benefits positioning performance but leads to high acquisition complexity. This paper proposes the combination of a CSS (Chirp Spread Spectrum) marker and the main body of traditional modulation methods for high dynamic application. The acquisition calculation complexity and mean acquisition time of the proposed signal are analysed and compared with the traditional signal. The result shows that the acquisition calculation complexity is just 26 % of the traditional signal under the parameters considered and the mean acquisition time of the proposed signal is also lower than the traditional signal. Hence, the proposed signal is able to decrease the mean acquisition time of the receiver under the constraint of calculation complexity and should be adopted for LEO high dynamic application.

This review essay focuses on recent developments and trends in the study of ancient Greek art. The publications covered date primarily to the period beginning in 2017–2018, though selected earlier works have been included where considered to be of particular merit or importance. Examples have been chosen to span and represent the long Archaic to Hellenistic phases (eighth–first century BC), and a full range of artistic categories and media have been featured in the discussions. In order to structure the large quantity of bibliography available, the presentation is divided into several broad categories according to themes (e.g. sites, reports, guides; exhibitions, conferences, Festschriften) or materials (e.g. sculpture and terracottas; metals, coins, gems, and jewellery). Where possible, digital resources applicable to the discipline have also been mentioned and cited. By way of conclusion, some general observations are made about the subjects of Greek art that seem not only to be the most prevalent in recent scholarship, but also transcend artistic medium, style, and scale – among them the body and adornment, senses and emotion, aesthetics and beauty, religion and performance, and archaeological contexts and intercultural connections.

Thelocarpon periphysatum sp. nov. is described from marl quarries in the Netherlands. The species is characterized by perithecioid ascomata that have a green-yellowish ring around the ostiole, abundant periphyses and periphysoids that are up to 120 μm long, the absence of paraphyses and the wide, oblong and often somewhat asymmetrical ascospores. The perithecia are immersed in black cyanobacterial crusts on calcareous rocks. A worldwide key is provided to the 30 species of Thelocarpon that are currently accepted.

The Shore Control Centre (SCC) is being developed and tested as an autonomous ship vessel with remote control. However, since the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) regulation's competency standard has yet to be altered, it must be revised and modified. Therefore, this study aims to define the competency of remote operators on an autonomous ship from ashore and develop a conceptual model of remote operators' competency. This study used both primary data by interviewing executives from four groups of maritime experts, and secondary data from academic databases, IMO, classification society and maritime companies. Academic databases are employed to conclude the academicians' view on remote operators’ (ROs’) competency and the other data sources are used to conclude the industrial view on the RO's competency. The content analysis technique was used to determine the presence of keywords or concepts from secondary data and develop a conceptual model. The study's findings present four main dimensions to indicate the development of future training and development programs for RO officers: navigation, cargo handling and stowage, controlling the ship's operation and care for persons onboard, and information technology; and present 45 competencies of ROs for managing autonomous ships from ashore, which a conceptual model can explain.

This article aims to overview the last 15 years of archaeological work on Crete (2007–2022) for the Roman and Byzantine periods. It is a resource that can provide the first step in the research process for those looking to investigate these time periods in Crete. It not only communicates recent discoveries and research, but also directs scholars to earlier key publications – which this article follows on from – and to an extensive bibliography of recently published research. After covering the main publications of the last 15 years and the workshops, congresses, and conferences that have taken place, it organizes the recent archaeological discoveries by site type. It begins by covering surveys of both the landscape and those conducted underwater that have been extensive across and around Crete. It then covers public buildings and infrastructure, domestic architecture, production and craft, and cemeteries. While it is not a complete listing of all finds, it summarizes the key discoveries, publications, and events in order to demonstrate the major developments for study of these time periods in Crete.

Aquinas holds that after death, the human soul can no longer change its basic orientation either toward God or away from him. He takes this to be knowable not only from divine revelation but by purely philosophical reasoning. The heart of his position is that the basic orientation of an angelic will is fixed immediately after its creation, and that the human soul after death is relevantly like an angel. This article expounds and defends Aquinas's position, paying special attention to the action theory underlying it.

In Who Are the Criminals?, John Hagan argues that legislators use “crisis framing” to influence how the general public thinks about crime. President Ronald Reagan used reports of a drug use epidemic fueled by organized crime as part of his crisis framing. In 1984, he signed the Comprehensive Crime Control Act (CCCA) as part of his “war on drugs.” The CCCA allowed law enforcement to use civil asset forfeiture (CAF) to keep or sell property that it suspected was connected to illegal activity. State legislators followed suit and passed their own CAF laws. Some critics argue that law enforcements’ use of CAF has disproportionately targeted minority populations. We draw on racial threat theory to examine connections between the size of minority populations and the use of CAF in California. Our analysis uses nineteen years of CAF cases filed with the California Attorney General’s Office. Consistent with racial threat theory, we find a positive association between the number of forfeitures in a jurisdiction and a logged measure of the percentage of Black residents, net of crime, and other jurisdiction attributes. Our results support concerns that law enforcement has incorporated CAF as a technique used disproportionately against some minority communities.

Intelligence played a critical role in the Irish War of Independence, though debate remains about the effectiveness of British information-gathering. Historians have focused largely on the intelligence war in Dublin. This article examines British Army intelligence in the 6th Division area (roughly the southern third of the island). It will contextualise British military intelligence before the conflict and traces the slow development of an intelligence organisation in the 6th Division. It then considers the sources and nature of British information gathering, particularly interrogation of prisoners and the collection and analysis of captured documents. Military intelligence summaries and a ‘Blacklist’ of I.R.A. suspects across the 6th Division are used to ascertain the quality of military intelligence products during the final stages of the conflict. The ‘Blacklist’ can be contrasted with I.R.A. unit arrest data and leadership lists, to assess the effectiveness of British military intelligence at a county level. This comparison provides a new measure of British performance, clearly revealing the limitations of British military intelligence in the 6th Division, particularly when compared to relatively more successful results achieved by crown forces in the Dublin District.
