This study addressed the frequency of occurrence of the epistemic modal elements that the Ex-president prefers to express in the selected State of the Nation Addresses of Ghana. The study adopted a qualitative approach. Purposively, the two addresses selected for the study are State of the Nation Address: 16th February 2001 and State of the Nation Address: 14th February 2008. The selected addresses are a good starting point for determining tendencies in the meaning expressed by the selected modal categories. The focus is on the semantics of the epistemic category of modality and other related variables within the contexts in which they are used. The data were analysed based on specific epistemic modal meanings and the modal elements expressed. It was observed that there were more expressions of certainty during the 2008 State of the Nation Address than the first one delivered by the Ex-president. Additionally, it is observed that the selection of a particular modal element in a particular context is primarily influenced by the interplay of the speaker and the participants involved. Therefore, an epistemic modal element used in a different linguistic environment may have a different contextual meaning from another. The lower expressions of uncertainty during the last State of the Nation, which ended the tenure of office of the ex-president, show that he was sure he had performed well and was bold enough to make categorical statements. The study exhibited some occurrences of expression of tentativeness with the use of modal verbs alone. All the categories recorded any instance of tentativeness. It is also recommended that politicians, spokespersons, and speech writers be cautious when indicating their information sources and how they obtain them. This helps maintain political credibility, which is the dominant index of the electorate's quest for people who know the conditions and problems prevailing in the country and their solutions.

The recent development of Mobile System-on-Chip (SoC) has completely changed the functionality of the contemporary smartphones, wearables, and IoT devices through enhanced computational strength but with stringent power and heat constraints. Mobile applications are becoming more complex (e.g., real-time computer vision, high-resolution imaging, on-device artificial intelligence, etc.) and SoCs have to provide high throughput, good work load distribution, and responsive multitasking without sacrificing battery life. To overcome these issues, modern SoCs are based on heterogeneous multicore designs, with big. LITTLE designs, special purpose accelerators, like NPUs and ISPs, and memory arranged hierarchies and backed with high bandwidth buses. Also, more sophisticated power-management approaches like Dynamic Voltage and Frequency Scaling (DVFS), clock gating, and power gating provide fine-tuning energy management in the active and idle conditions. Most recently, scheduling and thermal sensitivity resource allocation using AI has become a promising approach in increasing real-time refinement and flexibility. This paper gives a detailed discussion of performance-driven and power-efficient design methods in mobile SoCs, including architectural innovations, workload optimization, and built-in AI-assisted energy management. The discussion identifies major research trends, system-level developments, and new challenges defining next-generation mobile computing systems.

This work presents the results of an ethnobotanical research carried out in the territory of Serre Calabre, province of Vibo Valentia (Calabria, southern Italy). In this territory, the bond between the residents and the rural environment is still strong, because the small urban centers are placed in a predominantly agricultural and forestry environment still managed in a traditional way. The survey took place between January 2019 and July 2021. Data were collected through semi-structured interviews with locals. As many as 17 informants were interviewed and a total of 185 interviews were recorded. Plant specimens were collected under the indication of the informants and then deposited at the herbarium of the Mediterranean University of Reggio Calabria (REGGIO). The data were stored on a digital database and then statistically analyzed some synthetic indexes have also been calculated, such as Relative Frequency of Citation (RFC) and the Cultural Importance Index (CI). The investigation allowed to identify 84 taxa belonging to 39 different families, among which the most represented are Lamiaceae (23 interviews, 9 taxa), Asteraceae (22 interviews, 12 taxa). The identified taxa were prevalently cited for alimentary (46 interviews, 32 taxa) and healing (55, 27) uses. The results obtained show how the traditional knowledge about plants in the Serre Calabre area is still alive, however it is exclusive heritage of elderly people and often only in one or just a few informants. In fact, many practices are no longer in use and will not be transferred to the new generations.

The main goal of this paper is to study the effect of winding topology on coils electrical behavior in experimental way to take into account the self capacitance of coils, several coils are fabricated using copper wire with changing the number of winding layers and fixing the spiral numbers, in addition two coils was fabricated to study the effect of the winding wire diameter, the measured reactance and resistance of eddy current coils are done using precision LCR-meter with a frequency range from 0Hz to 5 MHz, the experimental results shows very remarkable interactions of resonator due to the changing of winding topology and his effect on self capacitance of coils.
