Abstract

Minóy is a rescue operation with several life rafts. Minóy-the-book provides an introduction and overview to the important noise music artist Minóy — the pseudonym of American electronic art musician and sound artist Stanley Keith Bowsza (1951-2010). Minóy’s audio compositions, often conjuring up an enigmatic world of almost dreadful depth, earned him a key position in the homemade independent cassette culture scene of the 1980s. Minóy-the-CD (available HERE) makes available nine of Minóy’s audio compositions that span the years 1985 to 1993. These were drawn from recently discovered archival material and selected by the editor and artistic director of the project, Joseph Nechvatal, in collaboration with composer Phillip B. Klingler (PBK). Klingler (co-producer and sound engineer) houses the Minóy archive and has re-mastered the tracks, most of which have never been heard before (it was thought that Minóy stopped recording in 1992). Minóy-the-book contains two written monograms of Minóy, one by close friend Amber Sabri and one by artist and art theoretician Joseph Nechvatal. There are three additional essays by Nechvatal, the first of which, “The Obscurity of Minóy,” recounts the history of the recovery of the audio material from obscurity. In the subsequent essays (“The Aesthetics of an Obscure Monster Sacré” and “Hyper Noise Aesthetics”), Nechvatal reflects on the artistic benefits of obscurity and situates Minóy’s deep droning palimpsest soundscapes within an original aesthetic-theoretical context of an obscure monster sacré, and also examines Minóy’s legacy in terms of current aesthetic responses to the surveillance state, couching Minóy’s mysterious and excessive compositions in terms of a general art of noise. In total, Minóy’s work undergoes a critical intricacy in terms of a contemporary art practice engaged in the fragile balance between production of, and resistance to, perceptibility. Nechvatal brings a subversive reading to Minóy’s work by presenting it as a form of hyper-noise artistic gazing, based in the flipping of figure and ground. The book also contains sixty black and white portrait images from the Minóy as Haint as King Lear series that photographer Maya Eidolon (Amber Sabri) created before his death in collaboration with Minóy (then known as Haint) and Stuart Hass (Minóy’s lifetime partner).

Abstract

The brainstem is one of the least understood parts of the human brain despite its prime importance for the maintenance of basic vital functions. Owing to its role as a relay station between spinal cord, cerebellum and neocortex, the brainstem contains vital nodes of all functional systems in the central nervous system, including the visual, auditory, gustatory, vestibular, somatic and visceral senses, and the somatomotor as well as autonomic nervous systems. While the brainstem has been extensively studied in animals using invasive methods, human studies remain scarce. Magnetic resonance imaging (MRI) as a non-invasive and widely available method is one possibility to access the brainstem in humans and measure its structure as well as function. The close vicinity of the brainstem to large arteries and ventricles and the small size of the anatomical structures, however, place high demands on imaging as well as data analysis methods. Nevertheless, the field of brainstem-(f)MRI has significantly advanced in the past few years, largely due to the development of several new tools that facilitate studying this critical part of the human brain. Within this scope, the goal of this Research Topic is to compile work representing the state of the art in functional and structural MRI of the human brainstem.

Abstract

Stochastic fluctuations are intrinsic to and unavoidable at every stage of neural dynamics. For example, ion channels undergo random conformational changes, neurotransmitter release at synapses is discrete and probabilistic, and neural networks are embedded in spontaneous background activity. The mathematical and computational tool sets contributing to our understanding of stochastic neural dynamics have expanded rapidly in recent years. New theories have emerged detailing the dynamics and computational power of the balanced state in recurrent networks. At the cellular level, novel stochastic extensions to the classical Hodgkin-Huxley model have enlarged our understanding of neuronal dynamics and action potential initiation. Analytical methods have been developed that allow for the calculation of the firing statistics of simplified phenomenological integrate-and-fire models, taking into account adaptation currents or temporal correlations of the noise. This Research Topic is focused on identified physiological/internal noise sources and mechanisms. By "internal", we mean variability that is generated by intrinsic biophysical processes. This includes noise at a range of scales, from ion channels to synapses to neurons to networks. The contributions in this Research Topic introduce innovative mathematical analysis and/or computational methods that relate to empirical measures of neural activity and illuminate the functional role of intrinsic noise in the brain.

Abstract

Correlated activity in populations of neurons has been observed in many brain regions and plays a central role in cortical coding, attention, and network dynamics. Accurately quantifying neuronal correlations presents several difficulties. For example, despite recent advances in multicellular recording techniques, the number of neurons from which spiking activity can be simultaneously recorded remains orders magnitude smaller than the size of local networks. In addition, there is a lack of consensus on the distribution of pairwise spike cross correlations obtained in extracellular multi-unit recordings. These challenges highlight the need for theoretical and computational approaches to understand how correlations emerge and to decipher their functional role in the brain.

Abstract

A classical view of neural computation is that it can be characterized in terms of convergence to attractor states or sequential transitions among states in a noisy background. After over three decades, is this still a valid model of how brain dynamics implements cognition? This book provides a comprehensive collection of recent theoretical and experimental contributions addressing the question of stable versus transient neural population dynamics from complementary angles. These studies showcase recent efforts for designing a framework that encompasses the multiple facets of metastability in neural responses, one of the most exciting topics currently in systems and computational neuroscience.

Abstract

In the toroidal tire cavity, standing waves can occur, leading to very high amplitudes. To investigate the cavity modes, experimental investigations are performed with pulse excitation, on a tire inner-drum test bench and under real operating conditions with a vehicle. At first, fundamental examinations are presented that focus on the identification of cavity modes and on the different system states. In a next step, various excitation mechanisms and important influencing factors are considered.

Abstract

This work systematically describes the mechanisms of tyre/road noise atdriving and braking torque based on measurements with different tyres. The studies on the influence of circumferential force on tyre/road noise can be divided into two different tire tread designs. One sub-chapter reports about a selective influence of force induced tyre/road noise using inclined groove edges. The influence of the circumferential stiffness of the tread blocks on the tyre/road noise is discussed afterwards.

Abstract

High-Tech Trash: Glitch, Noise, and Aesthetic Failure maps an archaeology of failure in a culture seemingly ill-equipped to deal with it. To better understand failure, Kane argues, we must abstract from our subjective, personal disappointments and see them as meaningful symbols of a broader human struggle. By connecting twenty-first century digital aesthetics to critical issues in the history of high-tech, the book elucidates what it means to be an error-prone, fallible human in an age of hyper technology; to fail again and again without recourse to anything but repetition.

Abstract

Worldwide, 278 million people are estimated to have moderate to profound hearing loss. Age-related hearing loss, also known as presbyacusis, affects approximately half of the population over 60 years old, making it the second most common cause of disability in older people. Hearing loss occurs when the sensory cells and neurons of the cochlea degenerate and die. The vestibular system, which holds the sense of balance, shares a common embryonic origin with the cochlea and together conform the inner ear. Balance problems are a trait of ageing to the point that balance ability is considered a sensor of physical decline and vestibular degeneration is the most common cause of falls in the elderly. Still the molecular bases of ageing in the vestibular system have not been studied in detail. Genetic and environmental factors contribute to the progression of age-related hearing loss (ARHL). Being noise the main environmental noxious agent for human hearing in the industrialized societies. There is no restorative treatment for deafness but functional replacement by means of prosthesis. Therefore, prevention and treatment of hearing loss is an unmet medical need. To develop innovative medical strategies against hearing loss, it is critical to understand the causes of ARHL and the essential pathways responsible for the manifestation of this complex disease. In this research topic, experts will discuss the stages and molecular elements of the damage and repair processes involved in ARHL, from cellular processes to molecules involved in aging. Oxidative stress takes a central stage as an essential element in the progression of injury and cell loss, and a target for cell protection strategies. Finally, the mechanisms of action and the potential of novel therapies for hair cell repair and protection will be discussed along with drug delivery strategies.

Abstract

Photon-counting image sensors represent a possible paradigm shift in solid-state image sensors. In these devices, photons are individually sensed and counted. To count photons, the devices must have high quantum efficiency, deep sub-electron read noise and the ability to read-out in digital form at high speed. This all-invited content from the top image sensor researchers around the world, reviews the state of the art of photon-counting image sensors in a variety of configurations, including CMOS image sensors and devices using avalanche multiplication, and for visible photons as well as higher energy photons such as ultraviolet and x-rays. New methods of creating image information from photon-counting image sensors is also described. This new emerging technology will have applications in low-light scientific imaging for aerospace and defense, and in the life sciences. It may also have applications in cryptography, communications, security cameras, 3D imaging and photography.
