A compact 12-element multiple-input multiple-output loop antenna array for a fifth-generation (5G) mobile phone is proposed. The operating band for the proposed antenna covers the long-term evolution 42 band, which spans a frequency range of 3.4–3.6 GHz. The size of the single antenna element is 5.85 × 4.9 mm2 (0.068λ0 × 0.057λ0), and 12 of these elements are positioned along two side edges of the mobile phone. This antenna is suitable for high screen-to-body ratio devices. The measured 6-dB impedance bandwidth is from 3.4 to 3.73 GHz. The measured total efficiency of the proposed antenna is 39–56% and the peak gain is 0–3.2 dBi. The transmission coefficient is less than −12 dB, the envelope correlation coefficient is less than 0.42, and the channel capacity is 45–50 bps/Hz.

This article provides the conclusions of a study of wars which are relatively well-documented through the ages and across the continents of human settlement. The evidence on which these conclusions are based is to be found in my book On Wars published by Yale University Press in July 2023. There are two main conclusions. First, the initial decisions to make either war or peace have almost always been made by a small handful of rulers and their advisors, regardless of whether they inhabit autocratic or representative political systems. They are to blame for war, not the peoples. Second, wars are rarely rational in either means or ends. They are rarely carefully calculated and they rarely bring the the desired ends, with the exceptions of where big powers aggress against small ones, “sharks swallowing minnows”, and of wars fought in self-defense where there is a reasonable chance of success. This is because in addition to the element of rational calculation so stressed by Realist theory, rulers and their advisors are substantially driven by combinations of emotions and ideologies.

This study investigated the psycholinguistic and child-related variables that modulate vocabulary development and the so-called receptive–expressive gap in child L2 learners of Gaelic with English as their L1. In total, 50 6- to 8-year-old English-Gaelic bilingual children attending Gaelic-medium immersion education were administered the English and the Gaelic Crosslinguistic Receptive and Expressive Lexical Tasks (CLTs). On the Gaelic CLT, children performed better on nouns than verbs. Accuracy was modulated by item-related variables such as the estimated age when a word is acquired and its morphophonological complexity. The receptive–expressive gap was larger in the minority L2 than in the majority L1 and did not narrow after 1 year of schooling. The gap was smaller for nouns than verbs in English but not in Gaelic. Exposure to English differentially affected the receptive–expressive gap across languages. This study offers new insights into the psycholinguistic and individual factors affecting the receptive–expressive gap in bilingual children in immersion education.

This article examines the pricing of a firm’s carbon risk in the corporate bond market. Contrary to the “carbon risk premium” hypothesis, bonds of more carbon-intensive firms earn significantly lower returns. This effect cannot be explained by a comprehensive list of bond characteristics and exposure to known risk factors. Investigating sources of the low carbon alpha, we find the underperformance of bonds issued by carbon-intensive firms cannot be fully explained by divestment from institutional investors. Instead, our evidence is most consistent with investor underreaction to the predictability of carbon intensity for firm cash-flow news, creditworthiness, and environmental incidents.

The Independent Review of the Mental Health Act 1983 found that people’s experiences and self-knowledge were mislabelled as a ‘lack of insight’. Insight, a psychiatric concept, is defined as an ability to recognise one’s mental illness, awareness of one’s symptoms and compliance with treatment. Across different jurisdictions, legal scholars have raised concerns about the influence of insight on legal provisions for psychiatric care and mental capacity assessments, given its prevalent use in psychiatry and its absence from statutory criteria. However, outside of these findings, little is known about people’s lived experiences of ‘insight’ and the law. This article draws on narrative and photo-elicitation interviews with psychiatric survivors to argue that insight is an extra-legislative proxy for regulating involuntary detention and other coercion masked as consent. Finally, this article draws on the capabilities approach to deliver a justice argument for creating real opportunities to provide informed consent in mental health settings.

Consider a minimal-free topological dynamical system $(X, \mathbb Z^d)$. It is shown that the radius of comparison of the crossed product C*-algebra $\mathrm {C}(X) \rtimes \mathbb Z^d$ is at most half the mean topological dimension of $(X, \mathbb Z^d)$. As a consequence, the C*-algebra $\mathrm {C}(X) \rtimes \mathbb Z^d$ is classified by the Elliott invariant if the mean dimension of $(X, \mathbb Z^d)$ is zero.

Stereo vision allows machines to perceive their surroundings, with plane identification serving as a crucial aspect of perception. The accuracy of identification constrains the applicability of stereo systems. Some stereo vision cameras are cost-effective, compact, and user-friendly, resulting in widespread use in engineering applications. However, identification errors limit their effectiveness in quantitative scenarios. While certain calibration methods enhance identification accuracy using camera distortion models, they rely on specific models tailored to a camera’s unique structure. This article presents a calibration method that is not dependent on any particular distortion model, capable of correcting plane position and orientation identified by any algorithm, provided that the identification error is biased. A high-precision mechanical calibration platform is designed to acquire accurate calibration data while using the same detected material in real measurement scenarios. Experimental comparisons confirm the efficacy of plane pose correction on PCL-RANSAC, with the average relative error of distance reduced by 5.4 times and the average absolute error of angle decreasing by 41.2%.

Indigenous peoples and ethnic minority groups often experience poor diet quality and poor health outcomes. Such inequities may be partially due to nutrition interventions not meeting the unique cultural and linguistic needs of these population groups, which could be achieved using co-creation and/or personalised approaches. Cultural adaptation or tailoring of nutrition interventions has shown promise in improving some aspects of dietary intake, but this requires careful consideration to ensure it does not inadvertently exacerbate dietary inequities. The aim of this narrative review was to examine examples of cultural adaptations and/or tailoring of public health nutrition interventions that improved the dietary intake and to consider implications for the optimal design and implementation of personalised and precision nutrition interventions. This review identified six examples of cultural adaptation and/or tailoring of public health nutrition intervention in Indigenous peoples and ethnic minority groups across Australia, Canada and the US. All studies used deep socio-cultural adaptations, such as the use of Indigenous storytelling, and many included surface-level adaptations, such as the use of culturally appropriate imagery in intervention materials. However, it was not possible to attribute any improvements in dietary intake to cultural adaptation and/or tailoring per se, and the minimal reporting on the nature of adaptations limited our ability to determine whether the interventions used true co-creation to design content or were adapted from existing interventions. Findings from this review outline opportunities for personalised nutrition interventions to use co-creation practices to design, deliver and implement interventions in collaboration with Indigenous and ethnic minority groups.

Perceived relationships between timbres are critical in electroacoustic music. Most studies assume timbres have fixed inter-relationships, but we tested whether distinct tasks change these. Thirty short sounds were used, from five categories: acoustic instruments, impulse responses, convolutions of the preceding, environmental sounds and computer-manipulated instrumental sounds. In Task 1, 46 non-musicians formed a ‘cohesive’ sonic ordering of unlabelled icons (sounds attached). In Task 2, they categorised the icons into four boxes. In Task 3 listeners separately ordered the sounds from each of Task 2’s boxes using the approach of Task 1. Tasks 1 and 2/3 revealed distinct orderings, consistent with conceptual flexibility. To analyse the orderings, we replaced conventional distance by adjacency measures, and described each system as a network (rather than spatial positions), confirming that the two task outcomes were distinct. Network analyses also showed that the two systems were mechanistically distinct and allowed us to predict temporally changing networks, modelling the observed networks as successive perceptions. Further simulated networks generated with the temporal model readily encompassed all possible pairings between the sounds and not just those we observed. The temporal network model thus confirms conceptual flexibility even in untrained listeners, clearly suitable for a composer to use.

English words containing inserted expletives, like absobloodylutely or unbefuckinglievable, are often said to be created by ‘infixation’. One goal of this work is to argue that such claims are self-contradictory. Infixes are affixes, but the expletives are not. Rather, they are themselves morphologically complex, are not bound, and can occur with words from different syntactic categories. Hence, the expletives are full words, and the only property they share with infixes is their phonologically determined insertion point. Due to these factors, I suggest that words like absobloodylutely are discontinuous compounds instead, in which the expletive forms a new word with the word it interrupts. I further argue that discontinuous compounding is even rarer than actual infixation cross-linguistically, which makes English a typological outlier. On the other hand, I try to show that the apparently idiosyncratic properties of expletive compounds are compatible with English compounding at a more abstract level. In addition, the article seeks to establish some tentative diachronic and cognitive mechanisms that may have led to the emergence and retention of expletive insertion. The overall conclusion is that, once morphological phenomena are analyzed in sufficient detail, novel structural patterns and parallels may emerge.

The central idea in trust-reform is to improve service delivery by granting professional autonomy and acknowledging the experiential knowledge of professionals. In this article, we study trust-reform bottom-up from the perspective of frontline care workers. Our aim is to discuss the challenges for care work and care workers who have been organised in self-managing teams, paying particular attention to the organising of the daily work in the teams. This study draws on data from four months of fieldwork in Norwegian municipal home care services for older people. The article sheds light on some problematic aspects in trust-reform regarding the relationship between frontline workers’ autonomy and responsibility on the one hand and the lack of authority and managerial support on the other hand. The study demonstrates that trust-reforms within public service delivery can be experienced as delegation of logistical tasks and enhanced responsibility instead of delegation of the authority that is necessary for professional care work to be performed. As such, trust-reforms risk obstructing rather than advancing their declared intentions of strengthening professional agency in care work, and rather than distributing management tasks, trust-reforms need to strengthen the management function in order to succeed.
