Single-ended and balanced 90–120 GHz microstrip power amplifier MMICs have been designed for cost-sensitive 5G and 6G backhaul in a commercial 6-inch, 0.1-µm GaAs process. At 108 GHz, measured output power is 20.4 and 22.5 dBm, respectively. At 120 GHz, measured output is 12.6 and 17.4 dBm, respectively. This is the highest reported for GaAs, among the highest reported to date for microstrip MMIC amplifiers at these frequencies and competitive with more expensive InP and GaN processes. Measurement is compared with simulation.

This review aims to critically evaluate the efficacy of long-chain ո-3 PUFA ingestion in modulating muscle protein synthesis (MPS), with application to maintaining skeletal muscle mass, strength and function into later life. Ageing is associated with a gradual decline in muscle mass, specifically atrophy of type II fibres, that is exacerbated by periods of (in)voluntary muscle disuse. At the metabolic level, in otherwise healthy older adults, muscle atrophy is underpinned by anabolic resistance which describes the impaired MPS response to non-pharmacological anabolic stimuli, namely, physical activity/exercise and amino acid provision. Accumulating evidence implicates a mechanistic role for n-3 PUFA in upregulating MPS under stimulated conditions (post-prandial state or following exercise) via incorporation of EPA and DHA into the skeletal muscle phospholipid membrane. In some instances, these changes in MPS with chronic ո-3 PUFA ingestion have translated into clinically relevant improvements in muscle mass, strength and function; an observation evidently more prevalent in healthy older women than men. This apparent sexual dimorphism in the adaptive response of skeletal muscle metabolism to EPA and DHA ingestion may be related to a greater propensity for females to incorporate ո-3 PUFA into human tissue and/or the larger dose of ingested ո-3 PUFA when expressed relative to body mass or lean body mass. Future experimental studies are warranted to characterise the optimal dosing and duration of ո-3 PUFA ingestion to prescribe tailored recommendations regarding n-3 PUFA nutrition for healthy musculoskeletal ageing into later life.

For migrant workers who do not have access to other means of income, the platform economy offers a viable yet exploitative alternative to the conventional labour market. Migrant workers are used as a source of cheap labour by platforms – and yet, they are not disempowered. They are at the heart of a growing platform worker movement. Across different international contexts, migrants have played a key role in leading strikes and other forms of collective action. This article traces the struggles of migrant platform workers in Berlin and London to explore how working conditions, work experiences, and strategies for collective action are shaped at the intersection of multiple precarities along lines of employment and migration status. Combining data collected through research by the Fairwork project with participant observation and ethnography, the article argues that migrant workers are more than an exploitable resource: they are harbingers of change.

Records of the Nubian Bustard Nubotis nuba range across the drier northern component of the Sahel zone in Africa from Mauritania through Mali, Niger, and Chad to Sudan. Reports of significant hunting pressure have caused it to be treated as IUCN “Near Threatened” for almost 40 years, but information relating to distribution and population trends remains scattered, anecdotal, and unevaluated. All accessible evidence bearing on its conservation is therefore assembled and reviewed here. The lack of records from Mauritania since 1984, Mali since 1974, and Sudan since 1988 suggests that populations there may now be very small and perhaps entirely extinguished. Records from Niger and Chad remain many, thanks largely to the assiduous reporting of observations on the West African Bird DataBase (WABDaB) by researchers involved in ungulate conservation. The national nature reserves of Aïr and Ténéré (RNNAT) and Termit and Tin-Toumma (RNNTT) in Niger and the Ouadi Rimé–Ouadi Achim Faunal Reserve (RFOROA) in Chad emerge as vital to the long-term survival of the Nubian Bustard, given the accumulating evidence in both countries of (1) widespread habitat degradation and conversion, as human populations and their livestock expand in numbers and range in the Sahel, and (2) intensifying persecution, as highly mobile and well-armed local poachers plus Gulf state hunters gain increasing vehicular access to the remotest regions, depleting all huntable wildlife (a Sahel-wide bird study, 2011–2019, encountered just 16 bustards of four species – none Nubian – in 487 observation days). Populations of Nubian Bustard must now be greatly fragmented and depleted, with many entirely lost, so targeted programmes to minimise disturbance, persecution, and damage to habitat in the three key reserves (including the exclusion of powerlines) are urgently needed. Ultimately however the survival of this and other endemic Sahelian species can only be secured via a huge programme of ecologically and economically sustainable management practices.

A key theme throughout Maimon’s works is a circularity he diagnoses at the heart of Kant’s response to Hume. The objective validity of Kant’s category of causality ultimately rests, Maimon argues, upon the logical status of the hypothetical judgement – on its inclusion among the forms of pure general logic. In turn, however, the inclusion of the hypothetical within pure general logic itself rests upon the objective validity of causal judgements. This article examines Maimon’s diagnosis and traces it back to a debate that has its origins in Wolff’s German Logic, concerning the relationship between categorical and hypothetical judgements.

While sin-based responses to divine hiddenness arguments are a road less travelled, they do nonetheless have a number of defenders in the contemporary divine hiddenness literature. I begin this article by exploring the various strategies that have been employed to attempt to motivate such accounts. What none of these strategies seem to take into account, however, is a cluster of facts about the correlation (or lack thereof) between a person's propositional attitudes about God and the degree to which that person displays the relevant moral and intellectual virtues. This article aims to fill this lacuna by mapping out the options available to defenders of sin-based responses in trying to cope with this cluster of facts. I argue that there may be resources available for preserving some aspects of the sin-based approach, but that taking stock of the aforementioned facts will ultimately require the positing of causal factors besides sin in order to generate a sufficient explanation of the phenomenon of non-belief.

Scholars studying the electoral breakthroughs of right-wing illiberalism have arrived at two general conclusions: while they largely rejected the hypothesis that this phenomenon is grounded in voters’ attitudinal shift, they have shown that those voting for the illiberal Right have distinguishing socio-economic and attitudinal characteristics. My analysis reconciles these two sets of findings by documenting the gradual emergence and transformation of the right-wing electorate in Poland in the period 1993–2018 and points to the consolidation of a right-wing partisanship as an organizing factor of the “illiberal moment.” Using the POLPAN panel dataset I find that populist and authoritarian attitudes indeed emerge in Poland in the twenty-first century to distinguish those supporting the Right more and more centered around the PiS party. These attitudes, however, have been incorporated in the context of partisan rivalry—right-wing voters, for example, are more supportive of limiting democratic procedures but only when the Right is in power. In the first decade of the twenty-first century PiS also politicized the lack of partisan consensus on the expansion of the welfare state. PiS incorporated this demand in its stance legitimizing the expansion of the welfare state through what was available in its ideological repertoire: national solidarity, national victimhood, and the idea of a sovereign nation-state joined under the umbrella of Catholic symbolism. This post-consensus polarization and asymmetrical political radicalization resembles the “illiberal moment” in Western Europe that followed the convergence between center-left and center-right parties but they lack a crystallized class-based political identity and social-democratic understanding of political economy to build on.

A spread-out lattice animal is a finite connected set of edges in $\{\{x,y\}\subset \mathbb{Z}^d\;:\;0\lt \|x-y\|\le L\}$. A lattice tree is a lattice animal with no loops. The best estimate on the critical point $p_{\textrm{c}}$ so far was achieved by Penrose (J. Stat. Phys. 77, 3–15, 1994) : $p_{\textrm{c}}=1/e+O(L^{-2d/7}\log L)$ for both models for all $d\ge 1$. In this paper, we show that $p_{\textrm{c}}=1/e+CL^{-d}+O(L^{-d-1})$ for all $d\gt 8$, where the model-dependent constant $C$ has the random-walk representation

\begin{align*} C_{\textrm{LT}}=\sum _{n=2}^\infty \frac{n+1}{2e}U^{*n}(o),&& C_{\textrm{LA}}=C_{\textrm{LT}}-\frac 1{2e^2}\sum _{n=3}^\infty U^{*n}(o), \end{align*}
