Double concertos for violin and cello with orchestra by Johannes Brahms and Vitalyi Kyreiko: genrе and style dimentions

The relevance of the article. The Concertos for violin and cello with symphony orchestra by J. Brahms (a moll, op. 102) and V. Kyreikо (a moll, op. 65) are considered in terms of embodying the artistic pursuit of composers of different eras and national schools. Genre-stylistic features are outlined, their individual and common features are revealed, which testify to the preservation and development of the tradition of the concert genre, the reinterpretation of the Brahms concert model in a new cultural context. It is emphasized that works belong to the type of symphonized concert, in which the means of symphonic transformation of thematic material, a rich polyphonic texture, complex forms of interaction between soloists and orchestra prevail. It is noted that the methods of symphonizing the musical fabric take place in accordance with the creative attitude of each composer, whose common stylistic space fits into the paradigm of romanticism — neoromanticism. Special attention paid to the V. Kyreiko’s concerto for violine and cello with orchestra, as the first in Ukraine double concert for string instruments, which is considered from point of imitation and development of the genre of instrumental concert. Emphasized the uniqueness of the author’s concept, which is revealed in the combination of deep musical content and clear form, understanding of the expressive possibilities of the violin and cello, and the disclosure of the natural beauty of the sound of the instruments.
 The main objective of the article is to compare the genre-stylistic features of the double concertos for violin and cello with the orchestra by J. Brahms and V. Kyreiko and to reveal the possibilities of their modern performance interpretation.
 The methodology of the research methodology includes the following methods: historical, which made it possible to determine the historical framework and attribute the work of composers to a certain era and style; genre-style analysis, which made it possible to reveal the stylistic features of musical expressiveness in the specified works of the composers; comparative analysis, thanks to which it became possible to compare intonation genre-style complexes in the work of composers; performance analysis, with the help of which the artistic and performance specifics of the double concerto for violin and cello with orchestra are highlighted in the aspect of updating the genre tradition of the 19th - second half of the 20th centuries.
 Results and conclusions. A comparative analysis of two original in design and methods of musical implementation of concertos for violin and cello and symphony orchestra by J. Brahms and V. Kуreiko allowed us to outline the wide genre and style space of existence of these bright artistic phenomena, which extends from the romanticism of the 19th century to the neo-romanticism of the 20th century, demonstrates the durability genre tradition, reveals the common features and individual differences of these works. Despite the different national and cultural context, both works embody the symphonic scale of the development of musical thought, they are marked by the breadth and ambiguity of lyrical and dramatic images. The thematic layer of the concerts is distinguished by its imaginative breadth: an epic story, elegiac romantic-song episodes, a multifaceted lyricaldramatic sphere, genre-dance finales with different emotional moods. The principle of thematic development is built on the basis of complementarity, contrasting juxtapositions of theme-images, avoidance of sharp clashes, associatively reminiscent of romantic poetic dramatic concepts. The double concertos for violin and cello by J. Brahms and V. Kуreiko demonstrate perfect skill in the presentation of each of the soloists, the construction of ensemble dialogues, and the interaction of the soloists with the orchestra. As a general trend, we state that both concerts continue the tradition of symphonizing the genre. Reviews of concerts performed by leading Ukrainian musicians of different generations (O. Horokhov — V. Chervov, B. Pivnenko — K. Polyanska) provide examples of standard performance versions, the performers' deep understanding of the composer's concepts, their inclusion in the general cultural and historical process. Undoubtedly, they are guidelines for further revealing the artistic potential of concerts.

DiAMoNDBack: Diffusion-Denoising Autoregressive Model for Non-Deterministic Backmapping of Cα Protein Traces.

Coarse-grained molecular models of proteins permit access to length and time scales unattainable by all-atom models and the simulation of processes that occur on long time scales, such as aggregation and folding. The reduced resolution realizes computational accelerations, but an atomistic representation can be vital for a complete understanding of mechanistic details. Backmapping is the process of restoring all-atom resolution to coarse-grained molecular models. In this work, we report DiAMoNDBack (Diffusion-denoising Autoregressive Model for Non-Deterministic Backmapping) as an autoregressive denoising diffusion probability model to restore all-atom details to coarse-grained protein representations retaining only Cα coordinates. The autoregressive generation process proceeds from the protein N-terminus to C-terminus in a residue-by-residue fashion conditioned on the Cα trace and previously backmapped backbone and side-chain atoms within the local neighborhood. The local and autoregressive nature of our model makes it transferable between proteins. The stochastic nature of the denoising diffusion process means that the model generates a realistic ensemble of backbone and side-chain all-atom configurations consistent with the coarse-grained Cα trace. We train DiAMoNDBack over 65k+ structures from the Protein Data Bank (PDB) and validate it in applications to a hold-out PDB test set, intrinsically disordered protein structures from the Protein Ensemble Database (PED), molecular dynamics simulations of fast-folding mini-proteins from DE Shaw Research, and coarse-grained simulation data. We achieve state-of-the-art reconstruction performance in terms of correct bond formation, avoidance of side-chain clashes, and the diversity of the generated side-chain configurational states. We make the DiAMoNDBack model publicly available as a free and open-source Python package.

Research ethics in the occupied West Bank and the Gaza Strip: between institutionalisation and the power of praxis

ABSTRACT ‘Research is a major aspect and fundamental component of many social struggles and movements for change' [Choudry, A. 2013a. “Activist Research Practice: Exploring Research and Knowledge Production for Social Action.” Socialist Studies/Études Socialistes 9 (1): 128 151. doi:10.18740/S4G01K, 128]. For Palestinians, research and knowledge production are vital for their ongoing anti-colonial struggle. However, there are various factors that restrict these processes and create an unsafe environment to produce liberatory knowledge(s) related to political and social activism. Some of these factors are the colonisers' prolonged oppression of Palestinian thought, narrative(s) and theorising, which is exacerbated by an oppressive Palestinian Authority – essentially an authoritarian body governing the Palestinian population in the West Bank and Gaza Strip; and the imposed hyper institutionalisation of academic and intellectual spaces, by donors’ strategies which create a need to meet global academic criteria by Palestinian institutions. This article engages with research ethics as a specific aspect within the process of knowledge production and dissemination. It critically looks at procedural research ethics that frame research conduct, including data generation, data analysis and modes of dissemination. In Palestine, research is being conducted under settler colonialism, apartheid and repressive ruling authorit(ies). This poses unique conditions that challenge standardised institutional ethics procedures and existing power dynamics within academic and research institutions. Additionally, in Palestine, there is a situation of excessive research – that is almost entirely dependent on foreign funding and the avoidance of clashes with the ruling authorit(ies). Hence, research ethics could be used as a tool for objectification and violence normalisation [Abdelnour, S., and M. Abu Moghli. 2021. “Researching Violent Contexts: A Call for Political Reflexivity.” Organization, 1–24]. The article argues that within the Palestinian context, institutionalised ethics procedures in universities and research institutions are almost never sensitive to the particularities of the context and/or the knowledge production and dissemination needs of a nation struggling for liberation. It also argues that utilising research ethics beyond standardised institutional procedures could be a tool for emancipation and the building of collective anti-colonial consciousness and critical education.

Clash Detection Using Building Information Modeling (BIM) Technology in the Republic of Kazakhstan

Research on the digital built environment in the context of identifying and minimizing clashes is a critical area to investigate owing to the significant influence of clashes on the construction process. This research aims to identify the current state of building information modeling (BIM) enabled clash detection in the architecture, engineering, and construction and operation (AECO) industry of the Republic of Kazakhstan. It further identifies the main reasons for clash occurrence, methods, and practices used to decrease the workload on BIM project teams. It also recognizes the existence of BIM departments (their type and functionalities). It aims to answer whether the transition from clash detection to clash avoidance is possible in a country where BIM technology has just penetrated. This research conducted a literature review and review of current regulatory documents regarding BIM technology, interviews with industry professionals, and a survey among construction companies and design organizations. Although the AECO industry of Kazakhstan has just entered the BIM environment, this research has shown that BIM-enabled clash detection and resolution processes are trying to evolve in parallel. It was concluded that the transition is difficult in a country where document assistance with clash detection and resolution is not well developed.

Not only size matters: limits to the Law of Three Consonants in French phonology

Grammont’s (1914) influential Law of Three Consonants (LTC) states that French schwa is obligatorily pronounced in any CC_C sequence to avoid three-consonant clusters. Later works have shown that schwa presence is also sensitive to the nature of the consonants involved, at least at the word and phrase levels. However the LTC is still generally considered as accurate under its original formulation to describe schwa-zero alternations at the stem level. The goal of the paper is to test whether the LTC should be relaxed even in this context. The paper presents two studies using judgment data to compare the behavior of schwa in derived words (stem-level phonology) and in inflected words (word-level phonology). The results of the two studies show that the nature of consonants involved in the CC_C sequence plays a role at both stem and word levels. Moreover, the same phonotactic asymmetries among consonant clusters are found in both contexts. The data therefore support a weaker version of the stem-level vs. word-level divide than what is usually assumed for French. This conclusion is strengthened by the results of a modeling study showing that a constraint-based grammar with the same phonotactic constraints across stem- and word-level phonologies provides a better fit to the judgment data from Study 1 and Study 2 than a grammar with different phononotactic constraints in the two morphosyntactic domains. The paper also replicates a number of earlier findings on the role of morphosyntactic domains, clash avoidance, and dialectal variation in schwa-zero alternations.

DfMA-oriented design optimization for steel reinforcement using BIM and hybrid metaheuristic algorithms

Steel reinforcement (also referred to as rebar) design plays an important role in reinforced concrete (RC) structures in terms of strength requirements, cost and buildability. Currently, rebar design is performed at the individual member level with few considerations of the interference between different intersecting members, leading to potential clashes and buildability issues. Design for Manufacture and Assembly (DfMA) is a cutting-edge technology concept that improves the design for higher buildability by incorporating knowledge from downstream manufacture and assembly activities into the early design phase. This paper presents an innovative DfMA-oriented approach for rebar design optimization with Building Information Modeling (BIM) and a hybrid metaheuristic algorithm. Firstly, activities related to the manufacture and assembly of rebar are identified to apply DfMA principles, followed by the proposed BIM-based optimization framework. Secondly, multi-objective cost design formulation including both the material cost and the installation cost is proposed, incorporating the design code requirements and DfMA considerations. Following this, key modules for implementation are presented including the rebar layout searching, the hybrid genetic algorithm incorporated with Hooke and Jeeves’s method for optimization and rebar clash avoidance. The illustrative example shows that the proposed approach can generate a series of practical rebar layouts, and a trade-off between the material cost and installation cost is found, which means excessive emphasis on minimizing one of them will lead to the rise of the other.

Simulation Study on an ICT-Based Maritime Management and Safety Framework for Movable Bridges

Maritime management is a crucial concern for movable bridge safety. Irregular management of water vehicles near movable bridges may lead to collision among ships and bridge infrastructures, causing massive losses of life and property. The paper presents a theoretical framework and simulation of an intelligent water vehicle management system for movable bridges corresponding to vehicle traffic responses. The water regime around the bridge is considered in virtually separated domains to estimate the desired safety actions based on the position of the approaching ships. An emergency clash avoidance control system is represented to prevent ship-infrastructure collision and ensure transportation safety. In addition, a simulation platform is developed specifically adaptable for movable bridge maritime and dynamic traffic management. The proposed theory is experimented using the simulation platform for different ship speeds and bridge-vehicle traffic volumes. Based on analyzing the velocity profile of approaching ships at different incidents, the bridge is found incapable of evacuating vehicles and unable to open promptly in case of speeding ships and high traffic density of vehicles on the bridge. Computational results show that the emergency control system is effective in reducing ship speed and prevent certain collisions. Lastly, the transportation policy for the newly proposed maritime management system is validated by real-world implementation in movable bridges across the world.

Against Words with Two Main Stresses: The case of Guugu Yimidhirr Revisited

The main aim of this article is to reexamine and argue against the existence of words with two main stresses which have been reported to occur in Guugu Yimidhirr (a Pama- Nyungan language, spoken in Queensland, Australia). Based on phonological evidence from patterns of clash avoidance and the distribution of secondary stress, it is claimed that in the alleged words with two main-stressed syllables, each syllable has a different metrical status. Only the initial one is main-stressed. The second is treated as an unstressed syllable by the metrical phonology of this language. The article also entertains and explores a tonal account in order to explain why some Guugu Yimidhirr words have been reported to bear two main stresses. Moreover, the article connects the discussion to “level stress,” a phenomenon similar to the Guugu Yimidhirr’s but found in some Mainland Scandinavian dialects. In contrast to previous analyses found in the literature to solve the puzzle posed by Guugu Yimidhirr double-headed words and Scandinavian “level stress”, this article finds no empirical support that motivates the weakening of the prosodic theory by either allowing recursion at the level of the Prosodic Word or by proposing the existence of disyllabic feet with both of their syllables stressed.

An Approach for Integrating Mixed Reality into BIM for Early Stage Design Coordination

Building Information Modelling (BIM) and its associated technologies have proved to be one of the most promising developments in the Architectural, Engineering and Construction (AEC) industry. Over the past few decades, the AEC sector has been restricted in its communication of design as a result of single interface methods based on 2D and 3D visualization of information. Thus, most issues with respect to construction are identified fairly late, resulting in costly changes. With the introduction of BIM, many other approaches to data visualization can be leveraged including Mixed Reality (MR) applications for the virtual representation of spaces and objects beyond 3D. MR offers a revolution in the virtual representation of objects and space through context awareness as well as the incorporation of information beyond 3D offering countless opportunities for more effective design visualization and coordination. Despite the capability of MR, however, few examples exist of its application to design coordination in the AEC. In addressing this gap this study proposes a novel methodology for the application of MR in design coordination as well as investigates the impact of introducing MR into BIM workflow with a focus on the identification and avoidance of clashes. A prototypical model of the MR design coordination is presented and discussed. Findings indicate that MR improves design productivity and quality but also highlights potential infrastructure issues inhibiting the mainstreaming of MR for design practice.

The Possibility of Building a Peaceful Regime on the Korean Peninsula Via Multilateral Approaches

Multilateral approaches such as the Korean Peninsula Energy Development Organization, the Four-Party and Six-Party Talks, and the Trilateral Coordination and Oversight Group (established by the USA, Japan, and South Korea to solve North Korea’s issues and to build a peaceful regime on the Korean Peninsula) have achieved few accomplishments since the Cold War. Exceptions include the avoidance of deadly clashes during ongoing multilateral talks at the time of serious situations including the nuclear crisis in 1994 and the Bush administration’s attempt to strike on North Korea with nuclear weapons. The USA has hesitated to conduct kind military relationships with North Korea because they seem to strongly recognize the high risk associated with physical conflict. Additionally, the USA and its allies have experienced North Korea’s ability with nuclear weapons. Many which have attempted to target the USA during the later years of the Clinton and Bush administrations. Dealing with North Korea contributes to the knowledge of those involved in the Six-Party Talks regarding how to work with the USA and others. Are multilateral approaches still efficient under this situation? Even with a number of several types of proposals such as China’s recent dual-track approach or double suspension approach—also backed by Russia—there seems to be no certain attempt to collaborate on building a peaceful regime. This paper will examine why multilateral approaches to building a peaceful regime post Cold War on the Korean Peninsula have forwarded little to a contextual perspective of the changing regional circumstances.

Clash Detection or Clash Avoidance? An Investigation into Coordination Problems in 3D BIM

Early collaboration is crucial if the final design is to be clash-free, and automation processes through Building Information Modelling (BIM) have the capacity to reduce clashes through 3D design coordination. Yet, current design practices are still dependent on clash detection and contemporary literature presents several reasons for this. This paper investigates the root causes of clashes with respect to achieving “clash avoidance” as proposed in PAS 1192-2 design phase specifications for BIM in the UK. Empirical data from BIM coordinators around the world was collected and analyzed using explanatory sequential mixed-methods. It was found that: (i) isolated working was the prime cause of high occurrences of clashes linked to mechanical, electrical and plumbing (MEP) 3D BIM systems; (ii) there is a link between non-BIM specific training (or the professional qualifications) of design practitioners with the high incidence of clashes; and (iii) the current structure of cloud-based common data environments (CDEs) does not facilitate clash avoidance and in fact, encourages isolated working in the early design stage by creating “digital information silos”. A conceptual framework for an open work in progress (OWIP) has been proposed to address this problem. These findings point to the need for more transparency during collaboration through CDE where designers from multidisciplinary backgrounds can engage in concurrent co-creation. This transparent and inclusive process could have consequences on how future architectural, engineering and construction (AEC) professionals are trained.

Computational protein structure refinement: Almost there, yet still so far to go.

Protein structures are essential in modern biology yet experimental methods are far from being able to catch up with the rapid increase in available genomic data. Computational protein structure prediction methods aim to fill the gap while the role of protein structure refinement is to take approximate initial template-based models and bring them closer to the true native structure. Current methods for computational structure refinement rely on molecular dynamics simulations, related sampling methods, or iterative structure optimization protocols. The best methods are able to achieve moderate degrees of refinement but consistent refinement that can reach near-experimental accuracy remains elusive. Key issues revolve around the accuracy of the energy function, the inability to reliably rank multiple models, and the use of restraints that keep sampling close to the native state but also limit the degree of possible refinement. A different aspect is the question of what exactly the target of high-resolution refinement should be as experimental structures are affected by experimental conditions and different biological questions require varying levels of accuracy. While improvement of the global protein structure is a difficult problem, high-resolution refinement methods that improves local structural quality such as favorable stereochemistry and the avoidance of atomic clashes are much more successful.

Crystal structure of Mox-1, a unique plasmid-mediated class C β-lactamase with hydrolytic activity towards moxalactam.

Mox-1 is a unique plasmid-mediated class C β-lactamase that hydrolyzes penicillins, cephalothin, and the expanded-spectrum cephalosporins cefepime and moxalactam. In order to understand the unique substrate profile of this enzyme, we determined the X-ray crystallographic structure of Mox-1 β-lactamase at a 1.5-Å resolution. The overall structure of Mox-1 β-lactamase resembles that of other AmpC enzymes, with some notable exceptions. First, comparison with other enzymes whose structures have been solved reveals significant differences in the composition of amino acids that make up the hydrogen-bonding network and the position of structural elements in the substrate-binding cavity. Second, the main-chain electron density is not observed in two regions, one containing amino acid residues 214 to 216 positioned in the Ω loop and the other in the N terminus of the B3 β-strand corresponding to amino acid residues 303 to 306. The last two observations suggest that there is significant structural flexibility of these regions, a property which may impact the recognition and binding of substrates in Mox-1. These important differences allow us to propose that the binding of moxalactam in Mox-1 is facilitated by the avoidance of steric clashes, indicating that a substrate-induced conformational change underlies the basis of the hydrolytic profile of Mox-1 β-lactamase.

Notes de recheche sur l'accentuation et le phrasé prosodique à la lumière des corpus de français

In this paper the main rules for stress assignment in French, the constraints relative to the formation of minor prosodic units (Accentual Phrases) and major prosodic units (Intonational Phrases, IP) are first recalled. A procedure developed in order to annotate semi-automatically these phenomena in different French corpora is then described. Finally the results of two studies are presented. The first one is conducted on a 4-hour long corpus (designed for the statistical study of regional variation in Swiss French). It aims at testing the robustness of two phonological rules implicated in the formation of Accentual Phrase in French (deaccentuation of pre-nominal adjectives (a sequel to the Align-XHead constraint), accentual clash avoidance rule). The second summarizes the main results obtained in the author’s PhD thesis (Avanzi, 2012). It is conducted on a set of data containing approximately 800 dislocated-sentences. It questions the weight of syntactic and information structure cues in front of prosodic structure cues in order to identify Intonational Phrase boundaries.

Polish stress: looking for phonetic evidence of a bidirectional system

AbstractThis paper reports on a study of Polish stress, the only uncontested example of a bidirectional system with internal lapses (Kager 2001, McCarthy 2003). The results indicate that Polish stress is non-iterative, a finding that seriously calls into question the existence of this particular stress type. An analysis of the acoustic prominence of syllables traditionally associated with different stress levels suggests that Polish simple words exhibit only one (penultimate) prominence. The stress pattern in compounds is less uniform; they can carry one or two (penultimate) stresses, depending on their prosodic structure. I analyse the distribution of stresses in compounds as governed by clash avoidance. Specifically, compound stems are parsed into separate PWds and assigned separate stresses only if the emergent trochees are non-adjacent. Hence, four-syllable compounds like /tsuʤɔ-ˈʑεmʲεts/ ‘foreigner’ have one stress, while compounds like /banaˈnɔvɔ-arbuˈzɔvɨ/ ‘banana-watermelon’ have two. I ascribe this pattern to the undominated ranking of the *FtFtconstraint.

Outflow Liquid Falling Position Control by Considering Lower Ladle Position and Clash Avoidance with Mold

The automatic pouring of molten metal from a ladle into a mold by a machine requires high-precision falling position control of the outflow liquid. In the previous studies, the precise falling position controls of the pouring outflow liquid into the sprue cup of the mold were proposed. However, it is supposed to increase amounts of splashing and air entrainment, since the conventional approaches are not considered the height of the pouring mouth of the ladle. Therefore, in this study, we propose a novel falling position control of the outflow liquid which makes the pouring mouth set as low as possible while avoiding clash between the ladle and the mold. In order to achieve the falling position control of the outflow liquid with both the lower pouring mouth position and the clash avoidance, the proposed approach gives the reference trajectory of the ladle movement considering not only the trajectory of the outflow liquid but also the positional relation between the ladle and the mold. The effectiveness of the proposed approach is verified by experiments of the automatic pouring robot systems with rectangle-shaped ladle.

SHIFT OF STRESS FROM ENDINGS IN THE SOUTH ŽEMAITIAN DIALECT OF RASEINIAI Summary The analysis of texts and the results of statistical research indicate that the classification of the South Žemaitian Raseiniai dialects according to the type of shift of stress from endings is not precise and fixed. Evidence of shift of stress from endings may be found in the entire dialect area, only in the northern and eastern parts of the area it is more regular and in the southern part it is less regular and less thoroughgoing. The research demonstrates that the types of stress shift that are typical of the Raseiniai dialect cannot be integrated into one common rule and that shifts of stress are still in the process of taking place. Most frequently the stress is retracted from the ending with a short vowel. Shift of stress from a long circumflex ending is much less common; it is optional and is mostly a result of phrasal intonation. Shift of stress from endings in the dialect under consideration follows the same pattern. The analysis of cases of shift of stress leads one to conclude that it is due to a number of factors: 1. In cases when a long unstressed ending is shortened, the word final stress becomes irrelevant and loses its distinctive function. After the stress loses some of its functions, it can be more freely retracted from the ending to any other syllable in the word. 2. The number of stressed short endings is reduced due to the position of the accent in the syllable which is usually stressed in the paradigm. From short endings the stress is retracted to another syllable which may take the stress in the course of inflection. 3. Stress clash avoidance is defined as the occurrence of two stresses in adjacent syllables. This speeds up the process of shift of stress. If two adjacent syllables receive the stress, the pronunciation (or articulation) of such a word or a two-word sequence usually becomes more complicated. That is why the final stress is retracted to another syllable (preceding the ending). Quite often the stressed syllable is followed by an unstressed syllable and then by a stressed again, i.e. there occurs an interval between stressed and unstressed syllables. In the case of a polysyllabic word with more than two syllables, the retracted stress falls on the syllable which is usually stressed in the word paradigm. 4. Intonation also exerts an influence on stress shift. In a phrase with a falling intonation the stress on the short ending, which is at the end of the phrase (which is less meaningful there), is more likely to move to another syllable than to preserve its original position. The stress falling on the final word in the sentence is more likely to be retracted to another syllable, than that in mid-position words. Apart from these factors, the dialect stress shift may be due to highly expressive and rapid speech when the significance of a word or a phrase may be emphasized by the logical accent. Due to the reasons specified above, one may conclude that the cases of shift of stress from short endings to other syllables are on the increase and thus reflect the latest trend in this sphere of phonetics. Shift of stress from long endings is occasional and may be explained mostly by the specific intonational pattern of the phrase.

Ship routing problem with berthing time clash avoidance constraints

We consider a ship routing problem in which multiple vessels have to perform pickups and deliveries of cargoes at various locations. The loading and unloading time of cargoes at pickup and delivery locations is significant, and at each of these locations we need to assign a time slot to each vessel to perform the loading/unloading task so as to avoid time clashes. This problem is motivated by the operations of feeder vessels and company-owned cargo terminals, where the shipping company wishes to coordinate the routing and the berthing time of its vessels. We develop a heuristic algorithm for the problem using set partitioning formulation and column generation techniques. The effectiveness of the heuristic is tested via extensive computational experiments.
