This paper deals with the advantages of so-called hybrid systems, that is, systems consisting of two or more different models. We present here two cellular automata coupled with artificial neural networks (neural CA). The first example is the model of a traffic regulating system. The cells of the CA represent different cars, and a certain neural net regulates the traffic. The second example shows a model of cognitive learning in dependency of social contexts. The cells of a CA consist of two types of neural networks. First results demonstrate the fruitfulness of this approach.

This paper presents an evolutionary approach to searching for cellular automata that accept gliders. The proposed technique is based on a specific fitness function taking into account spatial evolution, the number of living cells, and the presence of gliders. The results show that the genetic algorithm is a promising tool for finding cellular automata with specific behaviors, and then could prove to be decisive for identifying new automata that support universal computation.

Published: September 2024

We test a segmentation algorithm based on calculating the Jensen-Shannon divergence between probability distributions, on two symbolic sequences of literary and musical origin. The first sequence represents the successive appearance of characters in a theatrical play, and the second represents the succession of tones from the twelve-tone scale in a keyboard sonata. The algorithm divides the sequences into segments of maximal compositional divergence between them. For the play, these segments are related to changes in the frequency of appearance of different characters and in the geographical setting of the action. For the sonata, the segments correspond to tonal domains and reveal in detail the characteristic tonal progression of such musical compositions.

A new complex network model is studied on a Bulletin Board System (BBS) website. The model has as its vertices the identifications registered on the site, and an edge is linked if one article refers to another. Statistical characteristics of this network, such as degree distribution, average shortest-path length, and clustering coefficient are investigated. Centralities of this network including degree, betweenness, and closeness are presented. The model displays small-world characteristics with small average shortest-path lengths and a high clustering coefficient. It also exhibits scale-free topology but the exponent of power-law distribution does not exceed 2. The activity, control, and independence of communication on this network are stronger than that of some social networks. The phenomenon can be explained by the fact that the communication of viewpoints is very fast, and one person's change of view has a significant influence on other people using the BBS.

This paper presents a linear code referencing approach to the representation of individuals within a genetic programming scheme. This approach has been devised in order to confront various problems associated with genetic programming schemes. These are primarily the size of the available search space, the ability to pass through this search space, the construction of valid individuals after crossover and mutation, and the probability for the use of terminals and subpieces of an individual's solution. A comparison is made with existing methods and for the problems tested the presented method gives the best results.
Agent-Based Simulation of N-Person Games with Crossing Payoff Functions
Authors: Szilagyi Miklos N. , Somogyi Iren ,   Department of Electrical and Computer Engineering, University of Arizona, Tucson, AZ 85721
Published: September 2024

We report on computer simulation experiments using our agent-based simulation tool to model uniform N-person games with crossing payoff functions. We study the case when agents are greedy simpletons who imitate the action of their neighbor that received the highest payoff for its previous action. The individual agents may cooperate with each other for the collective interest or may defect, that is, pursue their selfish interests only. After a certain number of iterations the proportion of cooperators stabilizes to either a constant value or oscillates around such a value. The payoff (reward/penalty) functions are given as two straight lines: one for the cooperators and another for the defectors. The payoff curves are functions of the ratio of cooperators to the total number of agents. Even if the payoff functions are linear, four free parameters determine them. In this investigation only crossing payoff functions are considered. We have investigated the behavior of the agents systematically. The results show that the solutions are nontrivial and in some cases quite irregular. They show drastic changes for the Leader Game in the narrow parameter range of 1.72 ≤ P ≤ 1.75. This behavior is similar to that observed in [1] for the N-Person Chicken Game. Irregular solutions were also found for the Reversed Stag Hunt Game.
Optimal Launch Manifesting for Space Freight Forwarders
Authors: Hwang Junsub , Ahn Jaemyung
Published: September 2024

This paper proposes a novel framework to optimize a launch vehicle manifesting plan for small satellites from the perspective of a space freight forwarder. The forwarder in space logistics coordinates individual shipment orders from the launch customers and launch service providers like a freight forwarder in ground logistics does. An optimal launch manifesting problem is formulated as a variant of the vehicle routing problem involving the decisions on carriers, launch strategies (dedicated or multi-payload), launch dates, and satellite deployment sequences. A solution procedure based on the column generation method is proposed to address the challenges associated with the large-scale combinatorial optimization problem. A case study demonstrates the effectiveness of the proposed framework and solution procedure.
Adaptive-Quadratic-Neural-Network-Based Multifidelity Modeling Approach for Buckling of Stiffened Panels
Authors: Avni Yaşar Hüseyin , Gürses Ercan
Published: September 2024

This paper presents a method for predicting the buckling load of stiffened panels using multifidelity modeling based on quadratic neural networks (QNNs) with adaptive activation functions. The effectiveness of the proposed approach is demonstrated through a series of simulations on a range of stiffened panel configurations, and the results are compared to those obtained from traditional multifidelity and high-fidelity models in terms of accuracy and computational efficiency. Numerical experiments demonstrate that the model can accurately and efficiently predict the buckling load of stiffened panels while significantly reducing the computational cost of evaluating the surrogate model. In particular, the proposed adaptive quadratic neural networks (AQNNs) model achieves convergence approximately three times faster and four times less trainable parameters compared to traditional artificial neural networks while maintaining the same validation loss. This approach can significantly improve the design and optimization of aerospace structures by easily and quickly exploring various design configurations and finding stable and efficient configurations. This study highlights the potential of a new multifidelity modeling framework for predicting the buckling load and collapse load of aerospace structures by enhancing convergence speed and prediction accuracy while reducing the computational complexity of neural networks.

Published: September 2024

Background

Intraperitoneal vancomycin is commonly used to treat peritoneal dialysis (PD)-related peritonitis. Therapeutic drug level monitoring helps optimize the use of vancomycin in CKD patients. We studied whether sufficient serum levels were achieved in patients with PD-related peritonitis treated with the commonly used dose of vancomycin in patients with end stage renal disease.

Materials and Methods

All consecutive patients with PD-related peritonitis during 19 months were studied. Patients received IP Vancomycin 15 mg/kg Q96H and amikacin 2 mg/kg while awaiting culture reports. Vancomycin concentration in serum and dialysate was determined by a validated liquid chromatography-tandem mass spectrometry assay at 1, 12, 24, and 96 h. The primary outcome was the drug levels in serum and peritoneal fluid, and the secondary outcome was peritonitis treatment failure.

Results

A total of 45 episodes of PD-related peritonitis were treated, of which 41 fulfilled the inclusion criteria and were included in the PK analysis. Recommended serum vancomycin trough level of >15 mg/L was achieved in only two cases. Twenty-one episodes required catheter removal.

Conclusion

In patients with PD-related peritonitis, intermittent intraperitoneal administration of 15 mg/kg of vancomycin every 96 h does not achieve the recommended serum and dialysate levels of vancomycin. There is an urgent need for pharmacokinetic studies on commonly used IP antibiotics in the PD population to facilitate correct dose recommendations.

One male and a female 2-year-old Neapolitan Mastiff dogs weighing 41 and 40 kg, respectively, were presented to the University Veterinary Teaching Hospital, Jos, Nigeria, with complaints of continuous bleeding from the prepuce and vulva which were first observed about 2 months before presentation. Clinical examination revealed preputial bleeding of the male dog and serosanguinous vulva discharges with the presence of palpable masses with multiple nodules that were cauliflower-like. Cytological evaluations of smears from preputial and vaginal swabs revealed characteristic round cells with large eccentric nuclei, large nuclear-cytoplasmic ratio, and intracytoplasmic vacuolations as well as anisocytosis and anisokaryosis. Based on these cytological features, a diagnosis of canine transmissible venereal tumor (CTVT) was made in each case. Blood samples were collected for hematology and clinical chemistry. Debulking of the masses was carried out under general anesthesia using atropine sulfate and chlorpromazine as pre-anesthetics and Ketamine hydrochloride as induction and maintenance anesthetics. Following debulking, the resulting defect was reconstructed and the surgical wound was managed by daily wound cleaning and the administration of vincristine sulfate (0.025 mg/kg) slowly intravenously, ivermectin (0.3 mg/kg) subcutaneously, and piroxicam (0.3 mg/kg) and 20% amoxicillin (20 mg/kg) intramuscularly. There were no observed known vincristine sulfate-associated adverse effects as the dogs recovered and were discharged 3-week post-tumor debulking with no recurrence within 6 months of follow-up examinations. The debulked mass histologically showed several sheets of round neoplastic cells with prominent nuclei, mitotic figures, and infiltrating lymphocytes. Based on these findings, a diagnosis of CTVT was further confirmed. The hemogram showed moderate leukocytosis at day 1 in the bitch with a mild left shift at days 1 and 14 while clinical chemistry showed a marked increase in alkaline phosphatase, moderate increase in serum creatinine, and mild hypoproteinemia. In conclusion, management of CTVT with adjunctive vincristine sulfate and ivermectin combination resulted in complete healing with amelioration of known associated adverse effects.

Для решения системы дифференциальных уравнений использован метод контрольного объема. Параметры поля течения рассчитаны алгоритмом SIMPLE. Для итерационного решения систем линейных алгебраических уравнений использован метод ГауссаЗейделя с нижней релаксацией. Получены результаты расчетов параметров теплообмена при охлаждении потоком газожидкостной среды высокотемпературного металлического цилиндра с учетом парообразования. Определены значения температуры металлического цилиндра при охлаждении ламинарным потоком среды. Анализируется интенсивность изменения скорости охлаждения цилиндра в зависимости от доли газа в жидкости и времени процесса охлаждения.

The results of numerical modeling of heat transfer during the cooling of a metal cylinder body by a stream of gas fluid medium in a vertical annular channel are presented. The results are obtained on the basis of the mathematical model of the conjugate heat transfer of the flow of a gas fluid medium and a metal cylinder in a twodimensional nonstationary formulation, taking into account the axisymmetry of the fl ow of the cooling medium with respect to the longitudinal axis of the cylinder. To solve the system of differential equations, the control volume method is used. The flow field parameters are calculated by the SIMPLE algorithm. For the iterative solution of systems of linear algebraic equations, the GaussSeidel method with lower relaxation was used. The results of calculating the heat transfer parameters for cooling by a stream of a gas fluid medium of a hightemperature metal cylinder are taken into account, taking into account the evaporation. The values of the temperature of a metal cylinder are determined when cooled by a laminar flow of the medium. The intensity of the change in the cooling rate of the cylinder is analyzed depending on the proportion of gas in the liquid and the time of the cooling process.

По данным за 1881 2017 гг. для 12ти разных метеорологических станций России рассмотрены среднегодовые изменения межсуточных различий температуры воздуха DT и их скользящие средние по 11 годам DT11. Показано, что на этом интервале времени параметр DT11 существенно уменьшается, причем на многих станциях это уменьшение близко к монотонному. Отмечено, что величина DT определяется циклонической активностью атмосферы и поэтому DT11 является важной характеристикой изменения климата. Предложено объяснение, почему в начале XXI в. разрушительное действие циклонов усилилось по сравнению с прошлыми временами. Отмечена также возможная связь динамики параметра DT11 с изменениями нового параметра активности Солнца его возбужденностью.

According to the data for 18812017 For 12 different meteorological stations of Russia, the average annual changes in interday differences in air temperature DT and their moving averages over 11 years DT11 were considered. It is shown that at this time interval the parameter DT11 significantly decreases, and at many stations this decrease is close to monotonic. It is noted that the magnitude of DT is determined by the cyclonic activity of the atmosphere and therefore DT11 is an important characteristic of climate change. An explanation is proposed why at the beginning of the 21st century the destructive action of cyclones increased in comparison with previous times. A possible connection between the dynamics of the DT11 parameter and changes in the solar activity parameter its excitement was also noted.

В работе представлен автоматизированный RGB колориметрический прибор с RGB светодиодным излучателем и RGB трёхэлементным фотодетектирующим элементом, размещенными на внутреннем экране интегрирующей сферы для измерения спектров диффузного отражения образцов бумаги. Получены спектры диффузного отражения образцов белой бумаги, где фотооптический отбеливатель и тонирующая добавка не используется, а также при наличии их. Эти спектры качественно воспроизводят все особенности, обусловленные отбеливанием и тонированием исходной целлюлозной массы. Фотооптический отбеливатель формирует коротковолновую полосу поглощения при 420 нм и дает люминесцентную добавку к отраженному потоку излучения в синей области спектра 430480 нм. Тонирующая добавка снижает коэффициент отражения в средней области видимого диапазона при 500640 нм. Экспериментально определено количественное сопоставление параметра яркости B, определенного из спектров R() на RGB колориметре. На приборе Datacolor измерено референтное значение колориметра. Расчитана погрешность интерполяции, которая не превышает B 1 , что удовлетворяет требованиям производственного контроля для технологических циклов тонирования и фотооптического отбеливания.

The paper an automated RGB colorimetric device with RGB led emitter and RGB threeelement photodetecting element placed on the internal screen of the integrating sphere for measuring the diffuse reflection spectra of paper samples is presented. The spectra of diffuse reflection of white paper samples, where photo optical bleach and tinting additive is not used, as well as in the presence of them, are obtained. These spectra qualitatively reproduce all the features due to bleaching and toning of the original pulp mass. Photooptic bleach forms a shortwave absorption band at 420 nm and gives a luminescent additive to the reflected radiation fl ux in the blue region of the spectrum 430...480 nm. The tinting additive reduces the reflection coefficient in the middle region of the visible range at 500...640 nm. A quantitative comparison of the brightness parameter B determined from the R() spectra on the RGB colorimeter was experimentally determined. The interpolation error, which does not exceed B 1 , which meets the requirements of production control for technological cycles of toning and photooptic bleaching was calculated.

Self-driving laboratories and automated experiments can accelerate the design workflow and decrease errors associated with experiments that characterize membrane transport properties. Within this study, we use 3D printing to design a custom stirred cell that incorporates inline conductivity probes in the retentate and permeate streams. The probes provide a complete trajectory of the salt concentrations as they evolve over the course of an experiment. Here, automated diafiltration experiments are used to characterize the performance of commercial NF90 and NF270 polyamide membranes over a predetermined range of KCl concentrations from 1-100 mM. The measurements obtained by the inline conductivity probes are validated using offline post-experiment analyses. Compared to traditional filtration experiments, the probes decrease the amount of time required for an experimentalist to characterize membrane materials by more than 50× and increase the amount of information generated by 100×. Device design principles to address the physical constraints associated with making conductivity measurements in confined volumes are proposed. Overall, the device developed within this study provides a foundation to establish high-throughput, automated membrane characterization techniques.
An Efficient RI-MP2 Algorithm for Distributed Many-GPU Architectures
Authors: Snowdon Calum , Barca Giuseppe Maria Junior
Published: September 2024

Second-order Møller-Plesset perturbation theory (MP2) using the Resolution of the Identity approximation (RI-MP2) is a widely used method for computing molecular energies beyond the Hartree-Fock mean-field approximation. However, its high computational cost and lack of efficient algorithms for modern supercomputing architectures limit its applicability to large molecules. In this paper, we present the first distributed-memory many-GPU RI-MP2 algorithm explicitly designed to utilize hundreds of GPU accelerators for every step of the computation. Our novel algorithm achieves near-peak performance on GPU-based supercomputers through the development of a distributed memory algorithm for forming RI-MP2 intermediate tensors with zero inter-node communication, except for a single O(N^2) asynchronous broadcast, and a distributed memory algorithm for the O(N^5) energy reduction step, capable of sustaining near-peak performance on clusters with several hundred GPUs. Comparative analysis shows our implementation outperforms state-of-the-art quantum chemistry software by over 3.5 times in speed while achieving an eightfold reduction in computational power consumption. Benchmarking on the Perlmutter supercomputer, our algorithm achieves 11.8 PFLOP/s (83% of peak performance) performing and the RI-MP2 energy calculation on a 314-water cluster with 7,850 primary and 30,144 auxiliary basis functions in 4 minutes on 180 nodes and 720 A100 GPUs. This performance represents a substantial improvement over traditional CPU-based methods, demonstrating significant time-to-solution and power consumption benefits of leveraging modern GPU-accelerated computing environments for quantum chemistry calculations.
A simple solution form for triple tube heat exchanger with non-adiabatic condition on the outer wall by analogy with moving bed heat exchanger

Triple tube heat exchangers (TTHEs) are suitable equipment for thick viscosity products, with or without particulates, with various applications in the food and pharmaceutical industries. Of less widespread use than double tube heat exchangers (DTHEs), they generally perform better when compared to the latter. However, in the case of thermal models of "TTHEs with heat loss to the surroundings" (TTHEs-HL), there is no analytical solution in which the character of the roots has been analyzed. - except for the analogous problem of a "tubular moving bed heat exchanger, indirectly heated and with heat loss to the surroundings " (MBHE-HL), but only for certain flow arrangements -. Thus, it is not certain that the known solutions are of general application. Furthermore, regarding the important design parameter for co-current flow TTHEs, the crossover point, very little is known for TTHEs-HL. Also, recently published analogies provide an opportunity to synergistically increase the knowledge of TTHEs and MBHEs, for the case of non-adiabatic external surface. Aware of these needs and opportunities, the present work starts from a known analytical solution for a MBHE-HL thermal model and, by analogy, develops a compact form of an analytical solution for TTHE-HL, suitable for co-current and counter-current flow arrangements. The character analysis of the roots - not trivial for this solution - is performed according to a methodology recently described in the literature, consisting of several mathematical techniques. Approximate expressions for crossover point and temperature equality point between streams are obtained. In the case studies, the values calculated by the analytical solution and by a numerical solution by the finite analytical method (FAM), were shown to be very close. For the flow arrangements analyzed, it was possible to conclude about the generality of the solutions, in addition, the analogies between MBHE and TTHE made it possible to advance in the understanding of the thermal operation of these equipments. For a better understanding of the underlying physics, a scale analysis was performed.
