Microgrid (MG) technology evolves as a promising solution to deal with the intermittent renewable generations and frequently changing load demand. This paper proposes a fully distributed and bounded secondary control algorithm with flexible convergence time for voltage and frequency restoration. It also enables accurate active power sharing for an islanded MG, compared with the well‐known consensus‐based distributed control approach. The proposed control scheme achieves accelerated fixed‐time convergence. The upper bound on the convergence is established by using the Lyapunov stability theory. The bounded, distributed control approach restores the voltage and frequency in fixed‐time while sharing the active power precisely. Further, the proposed controller is adaptive to the communication topology change and supports the plug and play feature of MG. Extensive simulations have been pursued using MATLAB/SimPowerSyetem toolbox considering frequent load perturbation and communication topology change. The obtained results are analysed to verify the performance of the proposed control algorithm. It is observed that the proposed bounded input controller converges faster than the conventional method.

The authors are concerned in this study by bounded control of single input non-linear under-actuated mechanical systems. The authors focus the exposition on a feedback-based stabilisation-bounded control action shaped by saturation functions, and the proposed approach was illustrated via the design and the experimental evaluation of a simple stabilising controller for the cart–pendulum system, a well-known control benchmark. The proposed simple control strategy is built around a lumped linear continuous time-invariant description of the concerned under-actuated non-linear system. Namely, a model consisted of a cascade non-linear dynamical system constituted by a chain of four integrators affected by a high-order smooth non-linear perturbation. Assuming initialisation of the under-actuated system to the upper-half plane, the proposed feedback-based regulation design procedure involves the simultaneous combination of two control actions: one bounded linear and one bounded quasi-linear. Control boundedness is provided in both involved control actions by specifically designed saturation functions. The first bounded control action brings the non-actuated coordinate near to the upright position and keep it inside of a well characterised small vicinity, whereas the second bounded control action asymptotically brings the whole state of the dynamical system to the origin. The necessary closed-loop stability analysis uses standard linear stability arguments as well as the traditional well-known Lyapunov method and the LaSalle's invariance principle. The proposed control law ensures global stability of the closed-loop system in the upper-half plane.

[...]while the first founding Convention of industrial property law grants a special regime to well-known marks, even if it recognises a certain (limited) power of notoriety, this one, like the Agreement on Trade-Related Intellectual Property Rights (TRIPS), says nothing about well-known marks. Trademarks with an initial protection regime under common law and which, when they become well-known because of the quality of the goods or services they identify and the widespread awareness of the public concerned, enjoy a different protection regime from well-known trademarks and a much higher level of protection than common trademarks. For the average consumer (who rarely has the opportunity to make a direct comparison between different marks, relying on an imperfect image which he keeps in his memory and whose attention varies according to the category of goods or services in question1) the only important thing is that the mark helps him in his choice, that through it he can identify the commercial origin of the product or service, that the mark gives him a guarantee of the quality of the product/service and the possibility to revise his choices when a product/service which he identifies by the mark does not (any more) meet his expectations. [...]the Directive (EU) 2436/2015: (i) established the protection of trade marks with reputation (reputed) about which the Paris Convention is silent, or perhaps (probably) considered them to be the same as well-known trademarks and (ii) under the regime established in EU law, marks of reputation enjoy protection going beyond the specialty of the registered trademark, which means that the trade mark of reputation actually enjoys extended protection.

Heat shock protein 90 (Hsp90) is an ATP-dependent molecular chaperone which is essential in eukaryotes. It is required for the activation and stabilization of a wide variety of client proteins and many of them are involved in important cellular pathways. Since Hsp90 affects numerous physiological processes such as signal transduction, intracellular transport, and protein degradation, it became an interesting target for cancer therapy. Structurally, Hsp90 is a flexible dimeric protein composed of three different domains which adopt structurally distinct conformations. ATP binding triggers directionality in these conformational changes and leads to a more compact state. To achieve its function, Hsp90 works together with a large group of cofactors, termed co-chaperones. Co-chaperones form defined binary or ternary complexes with Hsp90, which facilitate the maturation of client proteins. In addition, posttranslational modifications of Hsp90, such as phosphorylation and acetylation, provide another level of regulation. They influence the conformational cycle, co-chaperone interaction, and inter-domain communications. In this review, we discuss the recent progress made in understanding the Hsp90 machinery.

Proper names comprise a class of labels that arbitrarily nominate specific entities, such as people and places. Compared to common nouns, retrieving proper names is more challenging. Thus, they constitute good alternative semantic categories for psycholinguistic and neurocognitive research and intervention. The ability to retrieve proper names is known to decrease with aging. Likewise, their retrieval may differ across their different categories (e.g., people and places) given their specific associated knowledge. Therefore, proper names’ stimuli require careful selection due to their high dependence on prior experiences. Notably, normative datasets for pictures of proper names are scarce and hardly have considered the influence of aging and categories. The current study established culturally adapted norms for proper names’ pictures ( N  = 80) from an adult sample ( N  = 107), in psycholinguistic measures (naming and categorization scores) and evaluative dimensions (fame, familiarity, distinctiveness, arousal, and representational quality). These norms were contrasted across different categories (famous people and well-known places) and age groups (younger and older adults). Additionally, the correlations between all variables were examined. Proper names’ pictures were named and categorized above chance and overall rated as familiar, famous, distinctive, and of high representational quality. Age effects were observed across all variables, except familiarity. Category effects were occasionally observed. Finally, the correlations between the psycholinguistic measures and all rated dimensions suggest the relevance of controlling for these dimensions when assessing naming abilities. The current norms provide a relevant aging-adapted dataset that is publicly available for research and intervention purposes.

Showrooming behavior on the part of consumers undoubtedly undermines the interests of brick-and-mortar (BM) retailers and hinders the growth of the physical economy. In response to this crisis, BM retailers can employ exclusive product strategies, although the questions of which specific strategy is most beneficial and what factors influence retailers’ choices remain unanswered. Based on utility theory and optimization theory, this paper investigates two strategies: the store exclusive brand (SEB) strategy and the well-known exclusive brand (WEB) strategy. First, we identify the pricing methods for both strategies employed by BM retailers, thereby revealing that the pricing of exclusive products under the SEB strategy should be higher than the corresponding pricing under the WEB strategy, whereas the pricing of nonexclusive products should be the opposite. Moreover, service levels should remain consistent under both strategies. Second, both strategies benefit retailers primarily by increasing their market share; interestingly, this process leads to the same overall growth in market share for BM retailers. Third, our analysis reveals that exclusive strategies always yield higher profits than nonexclusive strategies do. We also address the optimal choice between the SEB strategy and the WEB strategy for BM retailers. This choice depends on the relationship between the probability that a consumer can evaluate and purchase the best-fit product correctly online and the proportion of low-type consumers. If the former probability is low while the latter proportion is high, the SEB strategy is the best strategy. Otherwise, the WEB strategy is superior. Finally, numerical examples are provided to facilitate discussion of the effects of critical parameters on the outcomes of both strategies. Overall, this study explores the application of exclusive product strategies by BM retailers seeking to mitigate the negative effects of showrooming on service-oriented products; this research also emphasizes the crucial factors involved in the process of implementing these two strategies.

The focus of this study is on solving the coordination problem between distance relays (DISRs) and directional overcurrent relays (DOCRs), which is a complex nonlinear problem with various constraints. Ensuring proper coordination between DOCRs and distance relays is critical for maintaining the security of electrical networks. The primary objective of employing optimization algorithms is to determine the optimal operating time for zone-2 of distance relays, as well as the DOCRs setting, time dial setting (TDS), and pickup current (Ipickup). The optimization techniques must also guarantee that the primary and backup relays operate in sequence without any violation. To this end, both recent and well-established optimization algorithms are evaluated using an 8-bus network, with the aim of determining the DOCRs setting and the optimal operating time for zone-2 of distance relays. Furthermore, a comparative analysis of different optimization algorithms, including both traditional and recent techniques, is conducted.

Lucius Annaeus Seneca (4 BCE–65 CE) was a Roman Stoic philosopher, dramatist, statesman, and adviser to the emperor Nero, all during the Silver Age of Latin literature. The Complete Works of Lucius Annaeus Seneca is a fresh and compelling series of new English-language translations of his works in eight accessible volumes. Edited by world-renowned classicists Elizabeth Asmis, Shadi Bartsch, and Martha C. Nussbaum, this engaging collection restores Seneca—whose works have been highly praised by modern authors from Desiderius Erasmus to Ralph Waldo Emerson—to his rightful place among the classical writers most widely studied in the humanities. Written near the end of Seneca’s life, Natural Questions is a work in which Seneca expounds and comments on the natural sciences of his day—rivers and earthquakes, wind and snow, meteors and comets—offering us a valuable look at the ancient scientific mind at work. The modern reader will find fascinating insights into ancient philosophical and scientific approaches to the physical world, and also vivid evocations of the grandeur, beauty, and terror of nature.

Musical pedagogy has a long way of training and development. Over the decades, we can follow schools, systems and personalities through which this area is grounded. Based on various factors, such as the geographical location, the purpose of the system or school pursued, the possibilities of interpretation, the contemporary musical pedagogy enumerates well-known personalities, on whose researches this field is based. Dm. Kabalevsky’s name and his successors notably record in the musical-educational system of the Republic of Moldova.

This paper critically analyses the application of the trademark dilution doctrine under Jordanian trademark law, exposing fundamental deficiencies arising from statutory ambiguity and inconsistent judicial interpretation. The indeterminate definition of a “well-known” trademark in the second section has led to an indiscriminate classification of foreign marks as inherently well-known, resulting in courts extending automatic dilution protection without a rigorous evidentiary assessment. This practice fosters an implicit presumption favouring foreign trademark holders, potentially disadvantaging domestic marks that may not receive commensurate protection, thereby undermining the principle of equitable trademark enforcement. This paper argues for a systematic recalibration of Jordan’s dilution framework. A comparative analysis of the well-established dilution doctrines in the United States and European Union identifies jurisprudential best practices that could enhance the doctrinal coherence and judicial application of dilution protection in Jordan. Furthermore, drawing on the WIPO Joint Recommendation as a normative foundation, the paper proposes legal reforms to rectify inconsistencies, ensuring a more balanced and principled approach to trademark dilution. We argue that aligning Jordan’s legal framework with international standards strengthens the discourse on harmonising intellectual property law and ensuring equitable trademark protection in emerging markets.
