Speech Evolution as a Specialization of Symbolic and Expectation-based Communication
Authors: Fenk August
Published: July 2024

Language is viewed as a combinatorial symbol system, and speech as a specialization within multimodal symbolic communication. This paper assumes that a growing ability to suppress reflexive responses to stimuli (Striedter 2005) intensified anticipatory, hypothesis-testing activity, and that the (inner) try-out of vocalizations facilitated the exploitation of the potential of the symbol. Vocal utterances that turned out to be successful (e.g. in a put-the-baby-down scenario; Falk 2004), had the chance to become part of cumulative cultural transmission.The concept of the symbol in Peirce (1904, 1906) admits (i) a description of iconic visual gestures and of onomatopoetic vocalizations as “iconic symbols”, (ii) viewing the symbol as a representation of concepts, and (iii) viewing meaningful units in non-human communication, like monkey alarm-calls, as symbols. The symbolic function enables communicating abstract matters. And it enables “translatability”, for instance between vocal and visual-gestural components of utterances. Thus, we do not need the assumption (cf. Givon 2002) of an evolutionary transition from a rather iconic, visual-gestural to a “more symbolic” communication. Our approach to speech evolution amounts to a relatively parsimonious reconstruction that avoids the assumption of a qualitative difference in the cognitive systems of human and non-human animals (cf. Hauser et al. 2002) and the untestable implication that no other animal has the respective trait. The focus of the reconstruction is on specializations of working-memory capacities that amplify the auditory-vocal feed-back system, and particularly on specializations of extremely powerful statistical learning mechanisms (Saffran et al. 1996a,b; Saffran 2001). Advanced statistical learning and advanced “analogical abilities” (Gentner 2010) may explain the development of language early in childhood and early in the hominin evolution. We further discuss language universals that obviously reflect constraints of relevant information processing.
Hybrid Neural-Cognitive Models Reveal How Memory Shapes Human Reward Learning
Authors: Eckstein Maria , Summerfield Christopher , Daw Nathaniel , Miller Kevin J
Published: July 2024

Human reward-guided learning is typically modeled with simple reinforcement learning algorithms. These models assume that choices depend on a handful of incrementally learned variables that summarize previous outcomes. Here, we scrutinize this account by collecting and modeling a large dataset of human probabilistic reward-learning behavior using a hybrid approach that combines simple reinforcement learning models with artificial neural networks. Our results suggest that human behavior cannot be explained by any algorithm based exclusively on incremental updating of choice variables. Instead, they suggest that human reward learning relies on a flexible memory system that can learn rich representations of past events over multiple timescales. Hence, human reward-guided choices rely on more elaborate memory representations than previously believed.

Published: July 2024

The aim of the study was to carry out a comparative analysis of the results by determining of the particle-size distribution in different soil types by the 1) pipette method and 2) measurement device PARIO, using Integral Suspension Pressure plus method (ISP+). Location and time of the study. The study was performed in the Core Research Facility "Physico-chemical Methods of Soil and Ecosystem Research" and in the Department of Soil Cryology of the Institute of Physical-Chemical and Biological Problems of Soil Science the Russian Academy of Sciences. Methods. The determination of the particle-size distribution in soils was carried out by the pipette method and ISP+. Statistical processing of the analytical data was performed by Microsoft Excel and Statistica 12. Results. The determination of the degree of discrepancy between the results of repeated determinations of the particle-size distribution in soils obtained by the pipette method and ISP+ showed that the coefficients of variation (CV) were different for different fractions. High reproducibility of the results was obtained for the clay fraction. For fractions of the coarse and middle silt, the CV values did not exceed 10-20%. The largest variation in the between repeated measurements using both methods was obtained for the fine silt fraction. The assessment of the average difference and its significance for fine silt and clay fractions by the pipette method and ISP+ showed that there were no significant discrepancies. For the coarse and middle silt, such assessment showed significant differences. Most of the studied soils (14 out of 17) obtained the same classification according to the determinations of the soil particle-size distribution by the compared methods. Conclusions. The use of the PARIO measurement device for determining soil particle-size distribution allows to exclude disturbance of the suspension during the test run, to track the time and depth of sampling and to reduce measurement time significantly. This study showed the importance of taking into consideration the method of soil granulometry assessment, as results may be quite different, especially for the fractions of coarse and medium silt, thus affecting soil taxonomic attribution.

Published: July 2024

Indonesian government has targeted a gas production rate of 12 BSCFD by 2030 to balance the energy demands and the carbon emission reduction. To achieve this goal, a comprehensive evaluation of a gas field will be carried out regarding Recovery Factor, Stable Production Period (Plateau Time), Total Production Period, and Profits using simulation programme. Dynamic Reservoir Simulation is an integrated field development simulation that combines physics, mathematics, reservoir engineering, and computer programming to analyze and predict the wells performance or how fluid flows through reservoir rocks to the surface over time under various operating conditions. There are stages in the simulation include Reservoir Model Creation, Initialization, History Matching, and Production Performance Forecasting. This research is a continuation of static reservoir modeling research done by LEMIGAS, which started by reinitializing the model and ended by forecasting the production performance of field X using several gas production flowrate scenarios to find out the optimal gas production flowrate for Field X in ten years period. The simulation result showed that the best gas production flowrate for a ten-year period is 3 mmscfd. It gives 78,505% recovery factors, with cumulative profit of $40,915,872 USD over a plateau period of 6.6 years.
Reality Capture Technologies for Continuous Inline Quality Monitoring in Construction 3D Printing
Authors:   , Martin Michael
Published: July 2024

Extrusion-based construction 3D printing (C3DP) is an innovative and emerging technology aiming at the modernization of the construction industry. It uses robots and computer control to reduce the need for human labor and to decrease construction time and cost. C3DP creates elements layer by layer without using formworks, and it is critical to detect layer defects and deformations to ensure that each layer is printed with the desired dimensions. These defects can lead to a variety of issues during or after the construction process, including the collapse of freshly printed elements. In order to detect such deformations and to enable automated process adjustments, the extrudate must be inspected during the process and relevant data need to be collected. The purpose of this thesis is to provide two real-time systems of differing technologies, using LiDAR and structured laser light vision to encourage the progression of quality control in C3DP. Based on the quantitative data and measurement results, the LiDAR technique is able to continuously perform extrudate width and height and measurements with an average error less than 1.2 mm and a maximum error below 1.5 mm. The structured laser light vision system outperforms the LiDAR technique with a maximum error of less than 0.96 mm and an average error under 0.69 mm. The findings of this thesis also provide new insights into the influence of several parameters, such as the data collection cycle (LiDAR technique), extrudate size, number of layers, and extruder traversal speed on the performance of the proposed systems.

Human centered study of strawberry picking behavior for intelligent harvesting robot
Authors:   Department of Electrical Engineering, University of Moratuwa, Sri Lanka, Sendilkumaran S. , Pragalathanan A. , Laksman P. , Jayasekara A.G.B.P.
Published: July 2024

Strawberries, highly valued both commercially and for consumption, are predominantly cultivated in controlled environments like greenhouses. Despite these advantages, human labor remains a significant factor in strawberry production costs, especially during harvesting. To address this, there is a growing interest in developing strawberry harvesting robots. However, detecting strawberries poses challenges due to leaf shading, overlapping, and plant structure interference. Enhancing the visual object detection system is crucial for accurate and real-time detection. Given the vulnerability of strawberries to damage due to low mechanical strength during harvesting, we propose a stem-based harvesting method and plan to develop an efficient motion planning approach for the robot manipulator [1][2]. The goal is to enable the intelligent robot to navigate autonomously, picking strawberries with improved efficiency and minimal damage, thus transforming strawberry harvesting processes.

Identifying faults is a crucial element in the realm of preventive maintenance and the condition monitoring of transformers. For fault detection of transformers many different conventional or advanced techniques such as short circuit impedance measurement, vibration and sound analysis, frequency response analysis (FRA), dissolved gas analysis and machine learning or deep learning have been used. Offline methods of fault detection are being experimented since faults can be detected at the earliest stages, the detection process does not disrupt power supply. By using feature extraction of the fault current waveform, the performance of the fault detection algorithm can be improved, and the accuracy of fault discrimination can be increased. The purpose of this study is to evaluate the use of feature extraction of current in fault transformers using wavelet transform in order to enhance the effectiveness of the fault detection in transformers. A simulated PSCAD model derived using lumped parameter network in [1] is used for the generation of different types of faults and obtaining their fault current waveforms for feature extraction.

Published: July 2024

Ensuring the protection of natural habitats from growing coastal pollution includes the important task of cleaning plastics from beaches. The buildup of plastics and debris not only endangers marine life but also amplifies the problems, underscoring the need for effective intervention measures. While manual beach cleaning efforts are admirable, they are time-consuming and can lead to health issues for workers, including musculoskeletal diseases. Moreover, relying solely on manual labor proves inadequate given the large scale of the problem. Thus, there is an urgent need for advanced technological solutions capable of assisting and enhancing human efforts. This paper advocates for the deployment of intelligent beach cleaning robots as a promising approach towards a more sustainable and efficient strategy for mitigating coastal pollution.
Determination of the Nature of Hydrocarbons in the Barents Sea (Verification of Remote Sensing Data)
Authors: Nemirovskaya I. A. , Ivanov A. Yu.
Published: July 2024

Based on remote sensing data on the distribution of oil spills obtained using synthetic aperture radar (SAR) imagery of the Sentinel-1A and Sentinel-1B satellites in 2016–2022 and the results of the analysis of aliphatic hydrocarbons (AHCs) and polycyclic aromatic hydrocarbons (PAHs) in bottom sediments taken in 2019–2022, the nature of oil slicks in various areas of the Barents Sea has been established. It is shown that the distribution of oil slicks in coastal areas is greatly influenced by anthropogenic hydrocarbon inflow (mainly from shipping and fishing), which is confirmed by elevated AHC concentrations in coastal sediments (up to 73 μg/g) and in the composition of Corg (up to 3.6%). In the central and northern regions of the Barents Sea (station 7105, in the coordinates 75.2–75.3 N, 31.5–31.8 E), the grouping of oil slicks is due to natural seepage of oil and gas. This is confirmed by the anomalous concentration of PAHs in the lower horizons of the obtained sediment column, and their composition (the dominance of 2-methylnaphthalene, a marker of their oil genesis). At the same time, the proportion of light homologues in the composition of alkanes increased, which may indicate their formation in the sedimentary sequence.
On Volganism and Tectonics in the Evolution of the Guyots of the Magellan Seamounts (Pacific Ocean)
Authors: Pletnev S. P. , Syedin V. T.
Published: July 2024

This report is devoted to the analysis of original geological materials on the Magellan Seamounts in the Pacific Ocean, obtained by the authors in numerous voyages of R/V ʺGelendzhikʺ. This chain of guyouts does not have a common volcanic basement and apparently was formed in the second half of the Early Cretaceous on the oldest (middle-last Jurassic) fragment of the Pacific plate. The main points of view on the genesis of the Magellan Mountains are as follows: either they originated at the crossing of the transform fractures, or the Pacific plate moved them from the southern hemisphere to their present-day position. Because of their high degree of study, the Magellan Seamounts are one of the key sites for understanding the mechanism of the origin of linear chains in the ocean. A comprehensive analysis of new geological on the Magellan Seamounts has established the important role of magmatism and tectonics in the formation of the modern morphological shapes, sedimentation and influence on the paleooceangraphy. The periodic renewal of these processes from the Early Cretaceous to Late Cenozoic can be traced in the cyclicity of sedimentation, the permanent growth of ore crusts and the formation of secondary volcanic domes and cones.
Crust and Upper Mantle of the South China Sea (probabilistic-deterministic gravity model)
Authors: Petrischevsky A. M.
Published: July 2024

Rheological layering of a tectonosphere of the South China Sea (SCS) on the crust rigid (the depth interval of 5–30 km), viscous subcrustal (the depth interval of 30–70 km), rigid lower lithospheric (50–90 km), astenospheric (80–150 km) and rigid subastenospheric (the depth interval is more than 150 km) is established. Distributions of the density inhomogeneities connecting with the main tectonic events in SCS are caused by the Paleo-Pacific’s convergence, and later — the Philippine’a oceanic plate with the Philippine archipelago and further — with the Asian margin. In this zone by distributions of density contrast in a tectonosphere are tracing Cenozoic processes of a subduction, stretching, transformic shift and structure of the central type of the probable plume nature which form an evolutionary sequence: back arc, or paleo-oceanic spreading → the Philippine subduction → NE-stretching with shift → formation of the structure of the central type of a probable plume origin. The structures caused by convergence of the Asian continent with the Indo-Australian plate are isolated from the West Pacific margin, and the underthrsting of rigid lithospheric plates from the South under a lithosphere of the margin sea reflects traces of more ancient collision of fragments of the Gondwana with Asian continent.
Nonregular precession of a rigid body in three uniform fields

Published: July 2024

This article presents a solution to the problem of the conditions of nonregular precession of a rigid body in three homogeneous fields, in which the ratio of precession and proper rotation velocities is constant. It is shown that the precession of a dynamically symmetric body is possible at a precession velocity equal to, twice as large as, or twice as small as the proper rotation velocity. For each of the cases, the set of admissible positions of the centres of the forces and the relation between the body moments of inertia and constant nutation angle are given.

Acceleration of shear flow ina viscoplastic half-plane with a depth-varying yield stress
Authors: Georgievskii D. V. , Banko V. A.
Published: July 2024

The problem of acceleration from a state of rest of a shear flow in a viscoplastic half-plane is studied analytically when a tangential stress is specified at the boundary. It is assumed that the dynamic viscosity and density of the medium are constant, and the yield stress can change in a continuous or discontinuous manner depending on the depth. The entire half-plane at any moment of time consists of previously unknown layers where shear flow occurs and rigid zones. The latter can move as a rigid whole, or they can be motionless, such as, for example, a half-plane, to which disturbances caused by the action of tangential forces have not yet reached. To find the stress and velocity fields, a method is developed based on quasi-self-similar diffusion-vortex solutions of parabolic problems in areas with moving boundaries. The question of what conclusions about the depth distribution of the yield stress can be drawn from available measurements of the velocity of the half-plane boundary is discussed.

Molecular geometry features of 21 structurally characterized mononuclear octahedral dioxocomplexes of d2-rhenium(V) with mono-, tri- and tetradentate ligands [ReO2(Ltri)(Lmono)], [ReO2(Ltetra)] are discussed. In eleven cases, multiple-bonded Ooxo ligands are arranged in trans-positions to each other with OoxoReOoxo angles ranging within 172.9–180°. In ten structures, the ReO2 unit adopts cis-configuration with OoxoReOoxo angles vary within 106.7–124.8°. Re atoms possess either trans-octahedral coordination environment ReOoxo2X4 (X = N, P, As, O) or cis-structure ReOoxo2N2O2. Bonds Re=Ooxo in monomeric octahedral dioxocompounds d2-Re(V) (mean length 1.772 Å) are significantly longer those observed for monooxocomplexes d2-Re(V) (1.676–1.699 Å).

The conditions for the synthesis of sparingly soluble salts of lead, cadmium, mercury(II), copper(II) and iron(II, III) with anions of some organic acids HmL were given. Based on their solubility data (ionic strength I = 0.1), the solubility constants KS were calculated; based on the [Mn+]/MPCM ratio, conclusions were drawn about the applicability of low-toxic organic ligands as precipitators (antidotes) of toxic metal ions. It was shown that deactivation is also possible during the redox reaction of mercury(II), copper(II) with ascorbic acid. According to adsorption data on activated carbon, a number of ions were established to reduce sorption (deactivation ability): Pb2+ (96.6%), Fe3+ (95.4%), Hg2+ (80.6%), Cd2+ (42.4%). Adsorption data complemented the results of reagent methods for studying the detoxification of metal ions.

Selanjutnya dilakukan cross checkÂ  dengan tujuan menguji validitas data. Hasil kajian iniÂ  menunjukkan bahwa terdapat pola segitiga kekuatan dalam sistem politik, masing-masing; government, private sector dan civil society yang berperan penting dalam memotori proses pengambilan kebijakan. Pada konteks ini, influencer kemudian dikategorikan sebagai bagian dari civil society yang bertindak sebagai pemberi input dan feedback dalam proses pengambilan kebijakan. Di ranah Pemilihan Umum [Pemilu], pelibatan influencer dari kalangan selebritisÂ  bertujuan untuk membentuk opini publik, mendapatkan dukungan masyarakat, bahkan memenangkan kompetisi. Aura positif yang dimiliki oleh influencer juga dimanfaatkan oleh penyelenggara pemilu [KPU] dalam peningkatan partisipasi pemilih. Realita ini, banyak ditemui dalam penghelatan Pilkada di sejumlah daerah di Indonesia. Sebagai catatan penutup, perkembangan media sosial lambat laun mengalami pergeseran menjadi alat propaganda politik, terlebih di masa Pemilihan Kepala Daerah [Pilkada] di Indonesia, maka perlu dilakukan pendewasaan diri oleh masyarakat dalam bermedia sosial yang dimulai dari langkah sederhana seperti dengan melakukan cross check terlebih dahulu terhadap beragam informasi atau berita disajikan.
