The radical expansion of the written score as art object in late-twentieth and twenty-first-century music resulted in a rapid porting of extramusical objects into music’s textual realm, including a wide array of linguistic graphemes newly treated as musical material. This article suggests that the modern compositional use of scored parentheses, although rarely undertaken for identical aesthetic or formal ends, nevertheless always involves the generation of a virtual site for intimacy between irreconcilable bodies. Parentheses radically reveal the fragile contingencies of fallible musical embodiment: every– thing, every language, every intention, every body as foreign to everything else and yet nothing as foreign at all. Musical parentheses are the privileged site where the I knows that ‘I am not you’, that ‘you are not I’, that ‘you I do not know you I do not know’ – which is to say: they will reappear by the end as love.
To describe vestibular dysfunction accompanied by sudden sensorineural hearing loss and explore its potential prognostic role.
Methods
A total of 44 Idiopathic Sudden Sensorineural Hearing loss cases were enrolled. Pure tone audiometry (PTA) was performed at the first visit and three months after standard therapy. Patients’ improvement and severity of hearing loss were categorised based on Siegel and American Speech and Hearing Association criteria. Their recovery rate and factors affecting recovery were explored.
Results
The mean age of the participants was 52.1 years. The caloric and cervical vestibular-evoked myogenic potential test abnormalities were detected in 36.4 and 31.8 per cent of participants. Vertigo was present in 36.4 per cent at the first visit. Based on American Speech and Hearing Association criteria, 16 patients experienced at least 1 grade improvement to a less severe hearing loss status at the follow up. A total of 31.7 per cent of patients demonstrated complete or partial recovery. Vestibular dysfunction was associated with poorer PTA results.
Conclusion
Abnormal caloric and cervical vestibular-evoked myogenic potential tests, as well as the presence of vertigo, can indicate more profound inner-ear damage.
This article focuses on the poster child of grammaticalization, begoing to V. First expressing ‘motion with intention’, in Early Modern English the construction came to signify ‘motionless intention’. The grammaticalization process continued in Late Modern English with subjectification, so that ‘intention’ was gradually replaced by ‘prediction’. We study the process from Late Modern to Present-Day English in the 200-million-word fiction section of the Corpus of Historical American English (COHA), 1810–2009, for which we have gender metadata on the authors. We focus on the productivity of the construction by comparing type frequencies, i.e., the number of different verbs following begoing to. Our research questions are how the grammaticalization is reflected in the productivity of the construction, and whether the social factor of gender played a role in the process. We study the internal factors of mental verbs, inanimate subjects and passive voice; to this end, we use robust statistical methods to compare type frequencies and proportions of types over time. We also investigate the semantics of the verb types by drawing on techniques from distributional semantics. Our wider aim is to enrich the cognitively oriented theory of Construction Grammar with insights from historical sociolinguistics.
In a recent book, Bastiaens and Rudra (2018) claim that as governments embraced trade liberalization in the 1990’s, they experienced a revenue shock, and that democratic governments found it harder to repair the breach than did authoritarian ones. As a result, they argue, contemporary trade liberalizations have posed a danger to democracy by starving it for funds, forcing vulnerable governments to resort to politically unpopular policies. This is an important and provocative argument. However, good evidence contradicts its major premise. This research note critiques some data, presentation, and conceptual problems with the argument. It provides new analyses using the well-curated dataset from the International Centre for Tax and Development (ICTD, updated by UNU-WIDER), instead of the authors’ primary data from World Development Indicators. It shows that developing countries–and democracies especially–did not, in fact, suffer a revenue shock. On average, trade taxes constituted only a minor part of their government revenue. While the revenue they provided declined slightly over the period in question, this trend was overwhelmed by variation in other tax and non-tax revenues. As for total tax revenues, a key variable sometimes underemphasized in the book, ICTD data show that they expanded more rapidly in democratic developing countries than in non-democratic ones. Regression analyses with ICTD data also fail to confirm the authors’ finding of a revenue shortfall among developing democracies.
Methods of critique fashion their possible outcomes. Rita Felski (2015) makes the case for ‘postcritique’, a method of reading in which texts are worked with, understood in their own right, such that a more diverse range of styles and arguments might be understood. Robert T. Tally Jr. (2022) rejects this method, contending that postcritique claims to serve the text under analysis but, in adopting a standpoint of placid agreement, facilitates a mode of reading that diminishes the potency of the text itself and critical dialogue more generally. This article argues that postcritique has dominated the discourse surrounding ‘The New Discipline’, a manifesto of sorts written by composer Jennifer Walshe. The article offers an alternative critical reading of ‘The New Discipline’, arguing that the text is itself a Jennifer Walshe piece. The composer performs the role of a musicologist who falsely declares newness, inconsistently includes and excludes artists, and deploys a vague, if not contradictory, definition of bodies. The manifesto is addressed to an undisclosed but seemingly specific audience. I argue that these apparent shortcomings evoke themes of performance, irony and fictionalisation that are found elsewhere in Walshe’s work and make such a reading licit.
For every positive integer d, we show that there must exist an absolute constant $c \gt 0$ such that the following holds: for any integer $n \geqslant cd^{7}$ and any red-blue colouring of the one-dimensional subspaces of $\mathbb{F}_{2}^{n}$, there must exist either a d-dimensional subspace for which all of its one-dimensional subspaces get coloured red or a 2-dimensional subspace for which all of its one-dimensional subspaces get coloured blue. This answers recent questions of Nelson and Nomoto, and confirms that for any even plane binary matroid N, the class of N-free, claw-free binary matroids is polynomially $\chi$-bounded.
Our argument will proceed via a reduction to a well-studied additive combinatorics problem, originally posed by Green: given a set $A \subset \mathbb{F}_{2}^{n}$ with density $\alpha \in [0,1]$, what is the largest subspace that we can find in $A+A$? Our main contribution to the story is a new result for this problem in the regime where $1/\alpha$ is large with respect to n, which utilises ideas from the recent breakthrough paper of Kelley and Meka on sets of integers without three-term arithmetic progressions.
The Saami Council, founded in 1956, is one of the oldest Indigenous-led international organisations in the world. Despite this, its role and place on the world stage have been seldom examined, as has the place of internationally facing Indigenous Peoples’ Organisations more broadly. Using the organisation’s historical documents, among other sources, this article constructs a historic case study of the Saami Council from its founding in 1956 until the year 2000 to examine how it has evolved during this period and to better understand its standing within the greater international community. As the study discusses, since its inception, the organisation has evolved into an example of an Indigenous-led diplomatic organisation – one that came about through the changing political climate of the 1970s and solidified in the late 1990s. This evolution has implications for how we understand Indigenous-led advocacy and the role of non-state actors in international relations.
Neoclassicism is now largely eschewed within New Music. While there seems space in our pluralistic scene for modernist, postmodernist, minimalist, performative and conceptual music, the compositional values of neoclassicism seem out of step and anachronistic. This article advocates that classical principles should be put back on the table, arguing not for a return to a historical neoclassicism but rather for idiosyncratic forms of neoclassicism that emphasise characteristics such as entertainment, playfulness, clarity, forms of tonality and engagement with received form.
The accurate quantification of wall-shear stress dynamics is of substantial importance for various applications in fundamental and applied research, spanning areas from human health to aircraft design and optimization. Despite significant progress in experimental measurement techniques and postprocessing algorithms, temporally resolved wall-shear stress fields with adequate spatial resolution and within a suitable spatial domain remain an elusive goal. Furthermore, there is a systematic lack of universal models that can accurately replicate the instantaneous wall-shear stress dynamics in numerical simulations of multiscale systems where direct numerical simulations (DNSs) are prohibitively expensive. To address these gaps, we introduce a deep learning architecture that ingests wall-parallel streamwise velocity fields at $y^+ \approx 3.9 \sqrt {Re_\tau }$ of turbulent wall-bounded flows and outputs the corresponding two-dimensional streamwise wall-shear stress fields with identical spatial resolution and domain size. From a physical perspective, our framework acts as a surrogate model encapsulating the various mechanisms through which highly energetic outer-layer flow structures influence the governing wall-shear stress dynamics. The network is trained in a supervised fashion on a unified dataset comprising DNSs of statistically one-dimensional turbulent channel and spatially developing turbulent boundary layer flows at friction Reynolds numbers ranging from $390$ to $1500$. We demonstrate a zero-shot applicability to experimental velocity fields obtained from particle image velocimetry measurements and verify the physical accuracy of the wall-shear stress estimates with synchronized wall-shear stress measurements using the micro-pillar shear-stress sensor for Reynolds numbers up to $2000$. In summary, the presented framework lays the groundwork for extracting inaccessible experimental wall-shear stress information from readily available velocity measurements and thus, facilitates advancements in a variety of experimental applications.
It is plausible that a witness’s credibility is lowered if he testifies to an outcome that has low probability, but this is not always true. If the outcome has a low prior due only to its specificity (as in a fair lottery), witness credibility is not lowered by attesting to it. Even when witness credibility does drop as a result of the testimony, it can substantially confirm its contents, and agreement between independent witnesses can “give back” credibility that one witness lost. Formal modeling and analysis shed light on when each of these situations obtains.
Time-dependent fluid dynamics plays a crucial role in both natural phenomena and industrial applications. Understanding the flow instabilities and transitions within these dynamical systems is essential for predicting and controlling their unsteady behaviour. A classic example of time-dependent flow is the Stokes layer. To study the transition mechanism in this flow, we employ the finite-time Lyapunov exponent (FTLE) to demonstrate that a linear energy amplification mechanism may explain the intracyclic instability in the transitional Stokes layer, supported by favourable comparisons with experimental measurements of axial turbulence intensity. This complements existing theories applied to the Stokes layer in the literature, including the Floquet analysis and the instantaneous/momentary analyses, which have struggled to capture this experimental observation accurately. The FTLE analysis is closely related to the transient growth analysis, formulated as an optimisation problem of the disturbance energy growth over time. We found that the energy amplification weakens as the finite Stokes layer becomes more confined, and the oscillating frequency has a non-monotonic effect on the maximum transient growth. Based on these results, we recommend future experimental studies to validate this linear mechanism.
An experimental study was conducted in the CICLoPE long-pipe facility to investigate the correlation between wall-pressure and turbulent velocity fluctuations in the logarithmic region, at high friction Reynolds numbers ($4794 \lesssim Re_\tau \lesssim 47\,015$). Hereby, we explore the scalability of employing wall-pressure to effectively estimate off-the-wall velocity states (e.g. to be of use in real-time control of wall-turbulence). Coherence spectra for wall-pressure and streamwise (or wall-normal) velocity fluctuations collapse when plotted against $\lambda _x/y$ and thus reveals a Reynolds-number-independent scaling with distance-from-the-wall. When the squared wall-pressure fluctuations are considered instead of the linear wall-pressure term, the coherence spectra for the wall-pressure-squared and velocity are higher in amplitude at wavelengths corresponding to large-scale streamwise velocity fluctuations (e.g. at $\lambda _x/y = 60$, the coherence value increases from roughly 0.1 up to 0.3). This higher coherence typifies a modulation effect, because low-frequency content is introduced when squaring the wall-pressure time series. Finally, quadratic stochastic estimation is employed to estimate turbulent velocity fluctuations from the wall-pressure time series only. For each $Re_\tau$ investigated, the estimated time series and a true temporal measurement of velocity inside the turbulent pipe flow yield a normalised correlation coefficient of $\rho \approx 0.6$ for all cases. This suggests that wall-pressure sensing can be employed for meaningful estimation of off-the-wall velocity fluctuations and thus for real-time control of energetic turbulent velocity fluctuations at high-$Re_\tau$ applications.
