“‘Kwai’ is not an appropriate expression of God”: Stancetaking on Kaaps gospel music

The release of the song Die Here is Kwai (The Lord is Cool) by South African gospel singer Neville D in 2019 sparked debate about whether Kaaps is an authentic language for worship and praise and whether it ultimately is relevant for the textualization of gospel music in general. Although many would easily agree in the positive, we submit this paper to highlight how scriptural purity and standard language ideologies are some of the main drivers to the textualized performance of Kaaps gospel music. In this paper, we set out to analyze the various stances toward the song Die Here is Kwai. Data was drawn from a larger, longitudinal qualitative study that investigates the recontextualization of South African gospel music as a Kaaps-infused genre of music. We argue that Kaaps gospel music maximizes the genre potential of South African gospel music and highlights the diversity of voices in South African church discourses. We demonstrate the affective, epistemic, evaluative, and sacrificial stancetaking of gospel artists and commenters who align, disalign, and react against the publication of Die Here is Kwai (the stance-object), mediatized on a variety of digital communication platforms. Our analysis reveals stances from conservative traditional-religious voices and liberal religious voices expressing views on the production of Kaaps gospel music as text and performance. We argue that Neville D’s Kaaps gospel music challenges religious-linguistic views that attempt to reframe the sonic and spiritual life of Kaaps-speaking worshippers as ‘disrespectful’ and contrary to Christian ideologies that are steeped in scriptural discourses of purity and standard language ideologies

Strategic safeguarding: A game theoretic approach for analyzing attacker-defender behavior in DNN backdoors

Deep neural networks (DNNs) are fundamental to modern applications like face recognition and autonomous driving. However, their security is a significant concern due to various integrity risks, such as backdoor attacks. In these attacks, compromised training data introduce malicious behaviors into the DNN, which can be exploited during inference or deployment. This paper presents a novel game-theoretic approach to model the interactions between an attacker and a defender in the context of a DNN backdoor attack. The contribution of this approach is multifaceted. First, it models the interaction between the attacker and the defender using a game-theoretic framework. Second, it designs a utility function that captures the objectives of both parties, integrating clean data accuracy and attack success rate. Third, it reduces the game model to a two-player zero-sum game, allowing for the identification of Nash equilibrium points through linear programming and a thorough analysis of equilibrium strategies. Additionally, the framework provides varying levels of flexibility regarding the control afforded to each player, thereby representing a range of real-world scenarios. Through extensive numerical simulations, the paper demonstrates the validity of the proposed framework and identifies insightful equilibrium points that guide both players in following their optimal strategies under different assumptions. The results indicate that fully using attack or defense capabilities is not always the optimal strategy for either party. Instead, attackers must balance inducing errors and minimizing the information conveyed to the defender, while defenders should focus on minimizing attack risks while preserving benign sample performance. These findings underscore the effectiveness and versatility of the proposed approach, showcasing optimal strategies across different game scenarios and highlighting its potential to enhance DNN security against backdoor attacks

Partes do corpo falantes e agenciamentos: dando corpo à cidadania linguística

One of the greatest challenges of our times is that of lack of voice for abused bodies. These are the bodies of children and men and women who have inherited the brutalities of colonialism, plantation servitude and slavery and now re-live these miseries in the belly of a rampant global neoliberal and patriarchal capitalism. They are the racialized, sexualized, genderized and godless bodies that first took form in coloniality-modernity in conjunction with the emergence of MAN, the White, rational, disembodied male as HUMAN. They retain their shape today through technologies of vulnerability, with which the manufactured lack of voice works in dynamic synergy. This is particularly the case for South Africa, with its tender histories and distraught presents, raw emotion and sore vulnerabilities of racialized and neoliberal patriarchy. In this paper, we suggest that vulnerability, beyond its potentially devastating effect on souls and livelihoods, may also be a productive site for the articulation of alternative, and habitually silenced voices. In this regard, we explore how a focus on acts of Linguistic Citizenship may orientate thinking on voice and agency to different sites of the body, as well as allow insight into the complex technologies and practices of vulnerability.Uno de los mayores desafíos de nuestro tiempo es la falta de voz para los cuerpos maltratados. Son los cuerpos de niños, hombres y mujeres los que han heredado las brutalidades del colonialismo, la servidumbre de las plantaciones y la esclavitud, y ahora reviven estas miserias en el vientre del capitalismo global neoliberal y patriarcal. Son los cuerpos racializados, sexualizados, de género y sin Dios los que tomaron forma por primera vez en la colonialidad-modernidad junto con el surgimiento de MAN, el hombre blanco, racional, sin cuerpo, como EL HUMANO. Hoy en día mantienen su forma a través de tecnologías de vulnerabilidad, con las que la falta de voz fabricada funciona en sinergia dinámica. Este es particularmente el caso en Sudáfrica, con sus inquietantes historias y sus historias presentes, sus emociones crudas y sus dolorosas vulnerabilidades del patriarcado racializado y neoliberal. En este artículo, sugerimos que la vulnerabilidad, además de su efecto potencialmente devastador en las almas y los medios de subsistencia, también puede ser un lugar productivo para articular voces alternativas y habitualmente silenciadas. En este sentido, exploramos cómo un enfoque en los actos de ciudadanía linguística puede guiar el pensamiento sobre la voz y el albedrío a diferentes lugares del cuerpo, así como permitir una visión de tecnologías complejas y prácticas de vulnerabilidad.Um dos maiores desafios do nosso tempo é o da falta de voz para corpos maltratados.

Feasibility of mechanical extrusion to coat nanoparticles with extracellular vesicle membranes

Biomimetic functionalization to confer stealth and targeting properties to nanoparticles is a field of intense study. Extracellular vesicles (EV), sub-micron delivery vehicles for intercellular communication, have unique characteristics for drug delivery. We investigated the top-down functionalization of gold nanoparticles with extracellular vesicle membranes, including both lipids and associated membrane proteins, through mechanical extrusion. EV surface-exposed membrane proteins were confirmed to help avoid unwanted elimination by macrophages, while improving autologous uptake. EV membrane morphology, protein composition and orientation were found to be unaffected by mechanical extrusion. We implemented complementary EV characterization methods, including transmission- and immune-electron microscopy, and nanoparticle tracking analysis, to verify membrane coating, size and zeta potential of the EV membrane-cloaked nanoparticles. While successful EV membrane coating of the gold nanoparticles resulted in lower macrophage uptake, low yield was found to be a significant downside of the extrusion approach. Our data incentivize more research to leverage EV membrane biomimicking as a unique drug delivery approach in the near future

Lung Cancer in an Orthoprosthetist Using Vermiculite

Occupational exposure to certain substances would cause cancer. Herein, we report on a case of a 58-year-old former orthoprostethist who died from a lung adenocarcinoma. He had a 3 pack-year history of smoking and a single exposure to asbestos during his professional career. Between 1979 and 2010, he used vermiculite plaques daily to build medical prostheses, using no personal protective equipment. Contamination of vermiculite with amphibole asbestos has been described in Libby, Montana. Expert opinion on this case has raised the hypothesis of the use of this kind of vermiculite during this period and the occupational etiology of this cancer. It seems important to point out the possibility of vermiculite-related lung cancers in unusual occupations in order to better document such cases in the future

Experimental assessment of active electroacoustic absorbers for broadband room modes damping

Active electroacoustic absorbers are membrane absorbers actuated, through a feedback control loop and an electromechanical driver, so as to present optimal sound absorption on a broadband range around the membrane resonance. Taking advantage of the low resonance frequency of conventional loudspeakers, this technique appears as an interesting solution for the damping of low-frequency modes in rooms. This concept has direct applications to real life problems, such as the equalization of sound diffusion in the low-frequency range, or the mitigation of noise immission from external noise sources in habitations, among others. The performance of 4 prototypes of active electroacoustic absorbers is assessed inside a reverberant chamber with different sound stimuli (stationary broadband noise, pure tones). It is shown that the 4 electroacoustic absorbers prototypes, which represent only 0.1% of the total wall surfaces, achieve a global noise level attenuation of almost 8 dB, on a broad frequency range from 20 Hz up to 100 Hz, with individual mode attenuations up to 12 dB. Moreover, the modal decay times are significantly reduced, which is also verified with recordings of time-limited pure tones at several resonant frequencies in the room
