We further develop the abstract representation theory of affine Hecke algebras with arbitrary positive parameters. We establish analogues of several results that are known for reductive p-adic groups. These include: the relation between parabolic induction/restriction and Hermitian duals, Bernstein’s second adjointness and generalizations of the Langlands classification. We check that, in the known cases of equivalences between module categories of affine Hecke algebras and Bernstein blocks for reductive p-adic groups, such equivalences preserve Hermitian duality.
We also initiate the study of generic representations of affine Hecke algebras. Based on an analysis of the Hecke algebras associated to generic Bernstein blocks for quasi-split reductive p-adic groups, we propose a fitting definition of genericity for modules over affine Hecke algebras. With that notion we prove special cases of the generalized injectivity conjecture, about generic subquotients of standard modules for affine Hecke algebras.
For centuries, historic houses have presented a romanticized vision of antebellum life, obscuring the realities of slavery. Today, as heritage sites work to unpack their history, scholars often categorize any expansion beyond a traditional introspection as a “counternarrative.” This article challenges the overuse of this term, arguing that it reinforces a colonial framework where the dominant, often whitewashed, account remains the implicit norm. Through the interpretive methodology at Whitney Plantation, this article advocates for a reassessment of universal classification terminology used to describe antebellum heritage sites. It articulates the influence of scholastic intervention and inherent power dynamics in historical storytelling.
Rhinitis medicamentosa is a challenging condition resulting from prolonged nasal decongestant use. This study aimed to compare holmium laser turbinate reduction and partial turbinoplasty surgical options.
Methods
A retrospective cohort study was conducted, including 65 patients diagnosed with rhinitis medicamentosa, with a minimum post-operative follow up of 12 months. Symptom severity and quality of life were assessed pre- and post-operatively using the Sino-Nasal Outcome Test 22 (SNOT-22) and the visual analogue scale (VAS).
Results
Both surgical techniques resulted in significant post-operative improvement in SNOT-22 and VAS scores. Post-operative SNOT-22 total and obstruction scores were significantly lower in the partial turbinoplasty group compared with the holmium laser turbinate reduction group (p < 0.05). Post-operative VAS scores did not differ significantly between groups (p > 0.05). The partial turbinoplasty group demonstrated higher incidence of early post-operative complications.
Conclusion
Both holmium laser turbinate reduction and partial turbinoplasty are effective surgical options for rhinitis medicamentosa. Surgical technique selection should be individualised based on disease severity, patient expectations and risk tolerance.
Neolithic developments in central Europe cannot be adequately described through narratives of large-scale sweeping migrations and uniform sociocultural transformations. With such accounts, diversity and hybridisation are commonly relegated to the frontiers, whereas the inner landscapes are portrayed as homogeneously transformed. This paper highlights the biases that sustain this broad-brush image and, drawing on regional case studies, presents the increasing evidence that challenges it. Inhabitants of persistent enclaves maintained distinctive material representations, subsistence strategies, and hypothetically retained specific biological ancestry long after the surrounding regions had adopted the trajectories emphasised in conventional Neolithic schemes. Building on these observations, the paper introduces the concept of inner peripheries: regions situated among the canonical core zones, yet only loosely integrated into their networks. Shaped by specific environmental constraints and social processes, these inner peripheries constituted a structurally important component of broader Neolithic dynamics in central Europe and should not be sidelined. The concept provides a framework for understanding how alternative pathways of development coexisted with more conventional narratives and thus offers a necessary corrective to prevailing interpretative models.
Unsteady flows generated when a body approaches or departs from a granular bed arise in swimming, burrowing, and manoeuvring devices. Yet, the threshold for grain motion in such transients remains poorly modelled due to the complexity of the flow. Building on recent characterisations of the squeeze/suction flow and vortex-ring dynamics generated by a translating disk near a rigid wall, we test how these flow scalings translate into erosion thresholds when the rigid wall is replaced by a granular bed. We report laboratory measurements of the onset of erosion when the rigid circular disk is subjected to a single vertical stroke through quiescent water above the granular bed. The stroke length and travel time were varied independently to determine the critical velocity at which the granular bed is eroded for different minimum distances from the bed. Two erosion mechanisms are observed for disk motion towards the bed: during the stroke, the outward squeezing flow erodes grains near the edge, while after stoppage, the starting vortex or associated secondary vortices impinge on the surface. For motion away from the bed, only the early interaction between the inward suction flow and the nascent vortex entrains grains. The resulting dimensionless thresholds clarify the respective roles of radial flows and vortices in transient, impulsively driven erosion.
Given a positive, non-increasing sequence $a$ with finite sum equal to $1$, we consider the family of all closed subsets of $[0,1]$ whose complementary open intervals have lengths given by a rearrangement of the sequence $a$. We study the full range of possible $\theta$-intermediate dimensions of these sets and, under suitable assumptions on the sequence, we show that this range forms a closed interval, whose endpoints we compute explicitly. This paper fills a gap in the literature concerning the dimensional properties of complementary sets.
One way to understand the trajectories and outcomes of immigrant political incorporation is to examine changes in political participation across immigrant generations. Yet, patterns of political participation other than voting among Asian Americans across immigrant generations, particularly beyond the second generation, remain understudied. In addition, little empirical research has examined the mechanisms that generate the differences in the extent of political participation across immigrant generations. This study investigates whether, and to what extent, observed patterns of political participation across length of residence among first-generation immigrants and across successive immigrant generations can be accounted for by indicators of social integration, particularly engagement in political discussion with family and friends and involvement in civic organizations in the community, net of marriage patterns and other sociodemographic characteristics. Using data from the 2008 National Asian American Survey, the analysis focuses on the six largest Asian American groups: Chinese, Asian Indian, Filipino, Vietnamese, Korean, and Japanese. An overall political participation index is constructed by counting five dichotomous indicators of nonvoting political activity—campaigning, making political donations, contacting government officials, working with others to solve a community problem, and protesting—in the last twelve months. Descriptive results show that political participation increases with length of residence among first-generation immigrants and across immigrant generations, but tapers off in the third generation. Multivariate analyses indicate that these generational differences in the number of political activities are largely explained by variation in social integration, with the exception of recent immigrants with fewer than ten years of residence. Overall, the findings highlight social integration as a key mechanism of political incorporation among Asian immigrants and their descendants.
We present here the extraordinary find of an Early Neolithic mass deposition of headless human bodies at the LBK settlement site of Vráble-Veľké Lehemby. While various scientific analyses are under way, we present the archaeological context of this find and preliminary osteological and taphonomic observations. We discuss these in the light of a patterned and meaningful depositional complexity in Vráble, which embeds into a larger corpus of human remains in ditches surrounding LBK settlements in central Europe. Furthermore, we discuss the significance of the find for the overall discourse on the crisis at the end of the LBK period with regard to the role of violence and the nature of Early Neolithic cosmologies.
Selecting the ideal heart valve substitute for young patients with rheumatic heart disease remains challenging, especially in low- and middle-income countries. Both mechanical and biological prostheses have limitations, particularly in multivalvular disease.
Materials and methods:
We conducted a retrospective review of 12 patients with multivalvular rheumatic disease who underwent the Ozaki procedure between January 2022 and December 2024. Clinical, surgical, and early postoperative data were analysed.
Results:
Mean age was 25 ± 9 years; 58% were female. All had rheumatic aortic valve disease, 92% with isolated regurgitation, and 8% with mixed lesions. Concomitant mitral disease was present in all: 10 underwent bioprosthetic mitral valve replacement, and two underwent mitral valve repairs. Tricuspid repair was performed in two patients (17%). The Ozaki procedure was completed in all patients without intraoperative need for conversion to prosthetic valve replacement. No deaths were observed. Two patients (16.7%) required re-exploration for bleeding, and one (8.3%) underwent surgical revision due to a paraneocuspid leak corrected in the same surgical procedure. Another patient developed early neovalve dysfunction due to active rheumatic carditis, which resolved with medical therapy. Early postoperative echocardiography showed trivial or no aortic regurgitation in all patients. Mean hospital stay was 27 ± 10 days.
Conclusion:
The Ozaki procedure is a feasible and safe option for selected young patients with multivalvular rheumatic disease, offering advantages in resource-limited settings.
Jarociński and Karadi (2020) proposed a straightforward method to deconstruct monetary policy surprises into pure monetary policy shocks and central bank information shocks by exploiting the opposite-signed co-movements between stock price surprises and the two shocks. They highlighted that each shock brings about significantly different effects on the economy. Expanding upon their approach, this paper examines and compares a variety of alternative instruments, including New Keynesian- and Fama–French factor-based, for the decomposition of monetary policy surprises. Our results collectively suggest that Fama–French’s high-minus-low factor is a promising navigator, almost comparable to stock price surprises.
This article identifies a lunar day count in Zapotec inscriptions at Monte Alban. The lunar records that are accompanied by dates in the Mesoamerican 52-year cycle make it possible to determine intervals between recorded events. Seven placements of the resulting series of intervals in absolute time are consistent with dates of the lunar crescent’s first visibility at Monte Alban between 650 and 50 BCE; just one is also consistent with the seventeenth-century Zapotec calendar. The data show that Zapotec divinatory calendar dates likely began around noon, as in the sixteenth century, and that the return of the year-bearer on the year’s 261st day was celebrated in the afternoon by 222 BCE.
