This article is concerned with the following chemotaxis-growth system

\begin{equation*}\begin{cases}u_t = \nabla\cdot \left(\nabla u - u\bf{w} \right) + \rho u - \mu u^\alpha ,&x \in \Omega ,\ t \gt 0,\\v_{1,t} = \Delta v_1 - v_1 + u,&x \in \Omega ,\ t \gt 0,\\v_{2,t} = \Delta v_2 - v_2 + v_1,&x \in \Omega ,\ t \gt 0,\\\ldots \\v_{k,t} = \Delta v_k - v_k + v_{k - 1},&x \in \Omega ,\ t \gt 0,\\{\bf{w}}_t = \Delta {\bf{w}} - {\bf{w}} + \nabla v_k,&x \in \Omega ,\ t \gt 0,\end{cases}\end{equation*}

under the homogeneous Neumann boundary condition for u, vi and the homogeneous Dirichlet boundary condition for $\bf{w}$ in a smooth bounded domain $\Omega \subset {\mathbb{R}^n}\left( {n \geqslant 1} \right),$ where ρ > 0, µ > 0, α > 1 and $i=1,\ldots,k$. We reveal that when the index α, the spatial variable n, and the number of equations k satisfy certain relationships, the global solution of the system exists and converges to the constant equilibrium state in the form of exponential convergence.

Trichinellosis is a parasitic zoonosis caused by a nematode parasite of the Trichinella (T.) genus. It poses significant public health issues due to limited effective and safe treatment options, especially for the muscle-encysted larval stage. Citrus paradisi (C. paradisi), with its high content of flavonoids and polyphenols, has been recorded to possess anti-parasitic properties and numerous therapeutic applications. The present work aimed to assess the efficacy of C. paradisi extract peel extract as a therapeutic agent, either alone or combined with albendazole (ABZ), against T. spiralis in experimentally infected mice. Sixty-six lab-bred Swiss albino mice were divided into control and treatment groups, then received either ABZ, C. paradisi extract, or a combination of both during the enteral, migratory, and encapsulation phases of infection. Parasitological, histopathological, and immunohistochemical examinations were performed to evaluate the efficacy of the treatments. All treated groups displayed a highly significant difference (p < 0.001) in larval counts compared to the positive control group, with the combination therapy group having the highest efficacy and the lowest mean count value during different treatment regimens. In addition, treated groups showed improved muscle integrity compared to the positive control group. Moreover, the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) showed the highest expression reduction in the combination therapy group. These findings highlight the potential of C. paradisi as a complementary therapy to albendazole for treating trichinellosis through muscle larva reduction and mitigation of inflammation.

This study from the Luoxiao Mountains, southeastern China, combines historical information with paleoecological data from two wetlands, yielding a detailed reconstruction of landscape changes over recent centuries. The historical record suggests that people first settled in the region in the late Tang dynasty (618 to 907 CE), and wetland sediments show an increase in charcoal from about this time. During the Qing dynasty in the mid-seventeenth century, a temple complex and a Tea and Salt trade road were constructed near the study sites. Greater impacts are recorded in the wetland closer to the temple site. In the last few hundred years, pollen data show a regional decline of forest cover and the expansion of open vegetation as nearby lowland areas were settled and cleared for agriculture. Proxies for erosion show human impacts in the vicinity of the wetlands. Changes in charcoal inputs reflect regional fire activity, with elevated values around 1500 CE, low values during the Qing dynasty, and a subsequent peak during the twentieth century.

How can everyday entertainment shape gender politics in authoritarian regimes? Despite autocrats’ heavy control over media, political scientists studying authoritarianism largely neglect television programming. Particularly surprising given their target demographics, cooking shows are absent in political science gender analyses. Drawing from over 600 hours of Turkish cooking show content, I introduce conservative gender edutainment to capture the mechanisms by which TV shows facilitate authoritarian regimes’ gender construction projects. Using quantitative analysis of cooking show content, I first identify two complementary pedagogies — modeling and othering — that respectively teach adherence to, and vilify deviation from, regime-specified behavioral norms. I then use intertextual analysis to extract content that engagingly instructs viewers in the ideal woman in “New Turkey,” the neoconservative vision articulated by Turkey’s ruling (Justice and Development Party) AKP. Findings provide novel insight into vernacular channels of gender construction, while underscoring the added value TV-as-data holds for studies of identity politics in authoritarian contexts.

Justin Garson has argued, contrary to the claims of proponents of purportedly ahistorical theories of functions, that there are no ahistorical theories of functions. In the interest of satisfying uncontroversial desiderata on a theory of functions, the most influential ahistorical views all smuggle in history. I argue that Garson’s case relies on a misinterpretation of the ahistorical accounts he targets and that the details of the misinterpretation are instructive. They highlight often unquestioned assumptions about how a theory of functions fits into a broader account of scientific practice and what theoretical work a definition of function should do.

Over the past 20–30 years, women’s parties have consistently formed across Europe, aiming to improve women’s substantive representation by politicizing gender issues. Despite their potential impact on the policy agenda, empirical knowledge of the full range and scope of issues these parties mobilize is limited. This paper presents a novel mixed-method text analysis of the issue concerns in an original dataset of European women’s parties’ manifestos spanning a 30-year period. I find that parties across contexts share concerns in social justice and social policy. However, two subtypes of women’s party can be differentiated based on issue focus and framing. Essentialist women’s parties predominantly represent women’s material interests, whereas feminist parties additionally tackle structural gender inequality issues, including gender-based violence and human security. These findings provide a foundation for incorporating women’s parties into growing research on party competition over gender issues.

We strengthen two results of Moretó. We prove that the index of the Fitting subgroup is bounded in terms of the degrees of the irreducible monomial Brauer characters of the finite solvable group G and it is also bounded in terms of the average degree of the irreducible Brauer characters of G that lie over a linear character of the Fitting subgroup.

A paper exploring the epistemology of Edward Pusey’s work on Scripture.

LGBTQ+ people remain underrepresented in politics, leading scholars to examine a variety of barriers to office. Based on work on women in politics, this paper focuses on one possible barrier: political finance. Is there a political financing gap between straight cisgender and LGBTQ+ candidates? Are there inequalities among LGBTQ+ candidates? If so, what explains them? This article explores these questions by combining a dataset of out LGBTQ+ candidates in the 2015–21 federal elections with political donations data from Elections Canada. When we examine bivariate financing gaps, we find LGBTQ+ candidates receive less money than their straight cisgender counterparts. These gaps are gendered: queer cisgender women, transgender, and nonbinary candidates receive the least money. When we adjust for other variables, we still find LGBTQ+ candidates in the Conservative Party and transgender and nonbinary candidates across parties receive less money. This article contributes to work on gender and identity in campaign finance and LGBTQ+ representation.

The rise of antagonism between the German and Czech nationalist activists in the mid-19th century has been neither clearly explained nor convincingly dated. Although this is a topic closely linked to the history of nationalism, the state of research has paradoxically been misguided by the nationalist approach adopted by historians analyzing it. The reason is that nationalism was not the cause but just one response to a greater phenomenon. The aim of the article is therefore to clarify the German-Czech relationship in the broader context of European history and the history of international relations using the perspective of geopolitics and security. As it claims, it was not cultural, linguistic, or constitutional issues but the fear of external threats that caused the mutual distrust of political activists that led to hostility and conflicting policies. Under the impact of international events and within the context of their relations to other international actors this process originated in 1839 by the latest. During subsequent years it developed rapidly and became obvious during the 1848 revolutions. The article thus reveals that this year did not represent the beginning but merely another chapter in a process that had begun nearly a decade earlier.

Measurements of the radiocarbon (14C) content of subannual wood cellulose samples over the 1963 bomb spike have revealed an apparent delay between the increase in atmospheric radiocarbon content and that of wood cellulose. This delay is apparent in both coniferous and deciduous tree species and is of a magnitude of approximately 4 weeks. The delay in wood cellulose 14C change as measured in a Sitka spruce from Washington state, USA, was previously used to estimate the relative influence of tree physiological effects contra environmental effects. We repeated the measurements with the increased measurement precision of today’s AMS systems and compare the new results to the ones of a Scots pine tree from Trondheim, central Norway and a white oak from Oregon state, USA. The results challenge the assumption that the 14C tree ring records directly show the atmospheric 14C concentration of a homogeneous, zonally well-mixed atmosphere. Instead, the apparent 1963 delay reflects local influences of the ecosystem and tree physiology. The 1963/1964 data allows for exploratory modeling of the effects of biospheric decay CO2 and local environmental influences assuming the absence of stored photosynthates from the previous year. Compared to the 10–30% contribution from biospheric CO2, the effects of delayed incorporation of carbon into the wood cellulose and the effect of stored photosynthate are small in the conifers. Highly detailed 14C records of stem cellulose can, in combination with stable isotope studies, contribute to our understanding of variability of the local carbon cycle, climate, and the environment.
