Searching for Nearest Strings with Neural-Like String Embedding

We analyze an approach to a similarity preserving coding of symbol sequences based on neural distributed representations and show that it can be viewed as a metric embedding process.

Procesos creativos en entornos musicales inmersivos: un estudio de caso a través del análisis de metaversos. La Avatar Orchestra Metaverse en Second Life

La virtualidad se presenta como un espacio de creación y expansión de la realidad física. La percepción y la relación de los procesos creativos que giran en torno a lo virtual en lo referente a la música, la performance y la experimentación rigen e interaccionan nuestras realidades físicas, aún estando offline. Dichos procesos creativos son estudiados en la Orquesta virtual Avatar Orchestra Metaverse. Hemos navegado a través de la realidad creada por la Orquesta en el ciberespacio, bajo una metodología de estudio de caso -al que hemos llamado cybercase-, asistiendo y participando durante un tiempo en sus ensayos, junto a una posterior actuación. A través de un enfoque interdisciplinar basado en un proceso de análisis de material audiovisual y textual mediado por la presencia, entendida desde lo físico y lo virtual, exponemos los procesos creativos encontrados que subyacen bajo los miembros de la Orquesta, de modo descriptivo, y mediante el empleo de la teoría fundamentada. Como marco teórico mostramos los conceptos de música, espacio, tiempo y los procesos de comunicación gestados por la máquina y la virtualidad, todo ello mediado desde la percepción del ambiente y el interaccionismo simbólico. Presentamos dentro de este marco una revisión teórica del concepto de la creatividad enfocado desde la mecánica cuántica...

The Influence of the Guatemalan Municipal Orchestra's Curriculum on the Social Relations of its Members

The purpose of this case study is to determine the influence of the curriculum used by the Guatemalan Municipal Orchestra (GMO) upon the social interactions of its members. Social interactions include relations with families, teachers, and music colleagues. To determine this influence, the researcher framed the study using three main components: the impact of music in the development of children’s social skills; the curricula forming educational processes; and the characteristics of the Venezuela musical program, El Sistema. These foundations are explored via the tenets of participatory literacy. The data collection included interviews, surveys, and observation of students, parents, teachers, and administrative personnel. Two primary themes emerged from the data analysis: the development of a sense of community and the presence of intrinsic and external motivators implicit in the GMO environment. The final analysis suggests that curricular practices in the GMO positively influenced the development of students’ social interactions.

Hermes, a Concerto for Violoncello and Orchestra

This thesis consists of a large composition for violoncello and orchestra, together with an analytical paper in which I discuss my compositional techniques and some of their historical antecedents. The composition draws on the genres of imaginary musical theater, the symphonic poem, and the concerto. It was also inspired by the story of Hermes, the messenger god from Greek mythology. While the myth partially informs the compositional structure, the work is ultimately meant to showcase the versatility of the cello, the coloristic range of the orchestra (in some cases emulating the orchestral styles of previous composers), the balance of cello and orchestra together, and the eclectic invocation of many compositional techniques separately and simultaneously. These techniques encompass set theory (the use of unordered pitch collections), polytonality, and serialism. It is composed in a post-romantic style.

TRPV4: Molecular Conductor of a Diverse Orchestra

Transient receptor potential vanilloid type 4 (TRPV4) is a calcium-permeable nonselective cation channel, originally described in 2000 by research teams led by Schultz (Nat Cell Biol 2: 695-702, 2000) and Liedtke (Cell 103: 525-535, 2000). TRPV4 is now recognized as being a polymodal ionotropic receptor that is activated by a disparate array of stimuli, ranging from hypotonicity to heat and acidic pH. Importantly, this ion channel is constitutively expressed and capable of spontaneous activity in the absence of agonist stimulation, which suggests that it serves important physiological functions, as does its widespread dissemination throughout the body and its capacity to interact with other proteins. Not surprisingly, therefore, it has emerged more recently that TRPV4 fulfills a great number of important physiological roles and that various disease states are attributable to the absence, or abnormal functioning, of this ion channel. Here, we review the known characteristics of this ion channel's structure, localization and function, including its activators, and examine its functional importance in health and disease.

Simulation of Distributed Contact in String Instruments: a Modal Expansion Approach

Impactive contact between a vibrating string and a barrier is a strongly nonlinear phenomenon that presents several challenges in the design of numerical models for simulation and sound synthesis of musical string instruments. These are addressed here by applying Hamiltonian methods to incorporate distributed contact forces into a modal framework for discrete-time simulation of the dynamics of a stiff, damped string. The resulting algorithms have spectral accuracy, are unconditionally stable, and require solving a multivariate nonlinear equation that is guaranteed to have a unique solution. Exemplifying results are presented and discussed in terms of accuracy, convergence, and spurious high-frequency oscillations.
