Background

Severe acute respiratory syndrome coronavirus-2 is a global health care problem with high mortality. Despite early mortality seeming alarming, data regarding factors that lead to increased early mortality of COVID 19 patients is not well-documented yet. The objective of this study was to identify the risk factors of early mortality in patients with confirmed COVID-19 infections.

Methodology

A case-control study design was employed. With this, a total of 261 COVID-19 deceased recordings were reviewed. The cases of the study were recordings of patients deceased within three days of intensive care unit admission whereas, the rest 187 were recordings of patients who died after three days of admission. Data were collected using an extraction checklist, entered into Epi data version 4.4.2.2, and analyzed by SPSS version 25. After the description, binary logistic regression was run to conduct bivariate and multivariable analyses. Finally, statistical significance was declared at p-value <0.05, and an adjusted odds ratio with a 95% confidence interval was used to report the strength of association.

Result

The analysis was performed on 261 (87 cases and 174 controls) recordings. About 62.5% of the participants were aged above 65 years and two-thirds were males. The presence of cardiovascular disease (AOR = 4.79, with 95%CI: 1.73, 13.27) and bronchial-asthma (AOR = 6.57; 95% CI: 1.39, 31.13) were found to have a statistically significant association with early mortality. The existence of complications from COVID-19 (AOR = 0.22; 95% CI: 0.07, 0.74) and previous history of COVID-19 infection (AOR = 0.17, 95% CI: 0.04, 0.69) were associated with decreased risk of early mortality.

Conclusions

Having cardiovascular diseases and bronchial asthma was associated with an increased risk of early mortality. Conversely, the presence of intensive care unit complications and previous history of COVID-19 infection were associated with decreased risk of early mortality.

Uma abordagem cognitivista para a leitura em sala de aula de francês língua estrangeira
Authors: Rotta Alessandra Montera
Published: September 2022

A leitura é uma atividade familiar, mas complexa, porque implica processos cognitivos e perceptivos. A psicologia cognitiva, ciência que estuda os processos de tratamento da informação no ser humano, tem como eixo central a representação no funcionamento da linguagem. O leitor, ao levantar hipóteses, fazer predições e inferências, evocar seus conhecimentos anteriores guardados na memória, trabalha com suas capacidades cognitivas e constrói em sua mente uma representação da situação estabelecida no texto. A construção do sentido na leitura em língua estrangeira vem, pois, não apenas da decodificação das palavras, mas principalmente dos processos de alto nível que o leitor coloca em prática durante a sua leitura.
Percepção da responsividade a partir da Análise Verbo-Visual em tirinhas de humor
Authors: Da Silva Anderson Cristiano
Published: September 2022

Há alguns anos iniciou-se uma cobrança sobre os professores de línguas para um ensino que privilegie as contribuições teóricas advindas de Bakhtin, porém percebemos que alguns preceitos postulados por esse autor ainda não são bem apreendidos nas escolas de Ensino Básico. Assim, o objetivo deste trabalho é problematizar o conceito de responsividade, tentando aproximar a teoria bakhtiniana ao contexto pedagógico dos professores de Educação Básica. Para tanto, como referencial teórico-metodológico, analisamos três tiras de humor à luz da Análise Dialógica do Discurso. À guisa de conclusão, ao se falar em responsividade, precisamos considerar a relação entre os diversos elementos dos enunciados que interferem na constituição de sentidos.

Authors: Shim Hae Mee , Park HeeJoon , Han Jin Soo , Lee Donghyuck
Published: September 2022

With the increasing population of companion dogs, the social cost derived from their behavioral problems is increasing. Therefore, it is important to understand the environment to provide experience for dogs via interactions with their owners to prevent and solve these problems. The parenting behavior of dog owners as an environmental factor has a profound impact on the behavior development of dogs, as does the parenting behavior on children. Therefore, this study aimed to develop a scale to assess the dog owner’s parenting behavior. Exploratory factor analysis involving 300 participants resulted in a scale with four subscales, Positive Education, Involvement of Socialization, Intimacy, and Stable Responses, and 19 items. Confirmatory factor analysis was then performed to verify its reliability and validity. The result of parenting behaviors assessed by this scale was significantly different between a group with dogs with problematic behavior (n = 141) and those without (n = 159). Overall, a dog owner’s parenting behavior involves affection and control aspects, but the role required specifically in the control aspect is distinguished from the parenting behavior with children. The findings in the present study will provide people who have dogs with behavior problems with effective education that will help prevent dogs from developing behavioral problems.

In influenza vaccine development, Madin–Darby canine kidney (MDCK) cells provide multiple advantages, including large-scale production and egg independence. Several cell-based influenza vaccines have been approved worldwide. We cultured H5N1 virus in a serum-free MDCK cell suspension. The harvested virus was manufactured into vaccines after inactivation and purification. The vaccine effectiveness was assessed in the Wuhan Institute of Biological Products BSL2 facility. The pre- and postvaccination mouse serum titers were determined using the microneutralization and hemagglutination inhibition tests. The immunological responses induced by vaccine were investigated using immunological cell classification, cytokine expression quantification, and immunoglobulin G (IgG) subtype classification. The protective effect of the vaccine in mice was evaluated using challenge test. Antibodies against H5N1 in rats lasted up to 8 months after the first dose. Compared with those of the placebo group, the serum titer of vaccinated mice increased significantly, Th1 and Th2 cells were activated, and CD8+ T cells were activated in two dose groups. Furthermore, the challenge test showed that vaccination reduced the clinical symptoms and virus titer in the lungs of mice after challenge, indicating a superior immunological response. Notably, early after vaccination, considerably increased interferon-inducible protein-10 (IP-10) levels were found, indicating improved vaccine-induced innate immunity. However, IP-10 is an adverse event marker, which is a cause for concern. Overall, in the case of an outbreak, the whole-virion H5N1 vaccine should provide protection.

Authors: Zhou Ruijin , Wang Yingying , Zhang Xiaona , Jia Fengqin , Liu Yunli
Published: September 2022

Somatic embryogenesis receptor-like kinases (SERKs), a subfamily of receptor-like kinases, play important roles in response to abiotic stresses in addition to apomictic reproductive development in numerous plant species. The purpose of the present work was to determine if an ortholog of the SERK gene is present in the Diospyros lotus genome, isolate it and analyze its expression during embryogeny and abiotic stress. An ortholog of the SERK gene was isolated from the D. lotus genome, and designated as DlSERK1. The physical and chemical properties, protein structure, and evolutionary relationship of the DlSERK1 protein were analyzed by bioinformatics methods, and the expression of DlSERK1 gene during embryonic development and under low-temperature, salt, and drought stresses was examined through real-time quantitative PCR analysis. DlSERK1 contained 1,881 bp open reading frame encoding 626 amino acids, with a molecular mass of 69.18 kDa and pI of 5.34. DlSERK1 had strong hydrophilic property, signal peptide cleavage sites, and two transmembrane regions, indicating that DlSERK1 is a secretory protein. The secondary structure of DlSERK1 was consistent with the tertiary structure, both of which were dominated by random curls and alpha-helices. DlSERK1 had the typical structure of SERK proteins, and harbored multiple phosphorylation and glycosylation sites. Quantitative analysis showed that DlSERK1 was expressed during the embryonic development period, and the highest expression level was at 10 days post-flowering. The DlSERK1 expression level was down-regulated under low-temperature stress and up-regulated under drought and salt stresses. Our study showed that DlSERK1 was expressed in embryo development and could respond to low-temperature, drought, and salt stresses, which lays a foundation for further research on the function of SERK1 in the apomixis growth and development of environmental adaptation in D. lotus.

Published: September 2022

Multiple primary malignancies (MPMs) are defined as the coexistence of at least two unrelated primary malignancies in a single patient, with the tumors differing in their histology. MPMs in the same patient, when present within 6 months of the primary tumor diagnosis, are considered a synchronous occurrence. In this case report, we describe a 61-year-old man who presented with three distinct tumors concurrently in 2021: noninvasive urothelial carcinoma of the bladder, diffuse large B-cell lymphoma, and squamous cell carcinoma of the lung. We discuss the process of therapy and briefly review the literature. MPMs are increasing in incidence, requiring an interdisciplinary approach to diagnosis and treatment.
Students’ voices about English language learning in school and beyond
Authors: Carreño Mariangel
Published: September 2022

The research was carried out in a public secondary school with 16 to 18-year-old students in a context usually considered as an EFL one. The main goals were to discover what students said about learning English in and beyond the school and what led them to use English autonomously outside the classroom. A qualitative methodology was used. First, a questionnaire was proposed to 122 students to find out the uses of English outside the school; then, I selected students who were considered good learners of English by their teachers and who had learnt English only in secondary school and autonomously outside school. Based on that criterion, I investigated nine learners using a Facebook survey, two focus groups and learning logs. The idea of good language learners (GLLs) of English described by the teachers focuses on the relationship the learner establishes with the L2 and the external perceptions of what they do with it. On the other hand, GLLs do not share common features that can be generalized; every learner establishes a unique relationship with the L2 and uses varied and changing strategies. What GLL do share is an agentive approach to learning the L2 and a positive appreciation of its cultural artefacts. Learners mainly accessed these artefacts through ICTs working as learning affordances.

Published: September 2022

The degradation of polyvinyl alcohol (PVA) has been investigated using ultrasonic (US) as well as microwave (MW) irradiation techniques with the approach of process intensification based on different additives, such as Titanium Dioxide (TiO2), Sodium Lauryl Sulphate (SLS), Zinc Oxide (ZnO) and air. The effects of sonication time, initial polymer concentration, and temperature on the extent of reduction in viscosity have been thoroughly investigated using US as well as MW irradiation approaches. Basically, the degradation process has been optimized by utilizing two different ultrasonic reactors in a combined approach of ultrasonic horn and bath. The maximum extent of degradation of PVA was found to be 69.33% using MW irradiation with a required energy of 0.321 g/JL, and 62.47% using US horn with a required energy of 0.054 g/JL when operated at 0.1 g/L of TiO2 catalyst. The combination of US horn and US bath results in same degradation as 0.1 g/L of TiO2 catalyst with US horn. It has also been observed that the maximum degradation of PVA was obtained with a minimum treatment time of 3 min using MW irradiation, whereas the US horn required 40 min. Moreover, a lower extent of PVA degradation was obtained when additives were used, such as surfactants (SLS) and air. As a result, it can be inferred that the MW-assisted approach in the presence of process-intensifying additives/catalysts is the best approach for the degradation of PVA with a minimum energy consumption.
The Menzerath-Altmann law on the clause level in English texts
Authors: Wang Yaqin , Chen Heng
Published: September 2022

Menzerath-Altmann law (MAL) describes the relationship between the size of the construct and of its constituents, where the larger the whole, the smaller its parts. Despite numerous investigations dedicated to MAL, few studies have observed the relationship syntactically, especially at the clause level. The present study investigates three units in which clauses in English can be measured, i.e., argument, phrase, and word, by fitting MAL to the relationship between the size of the clause and its constituents. Results show that 1) clause length in phrases can be well fitted by probability distributions, while the goodness-of-fit is less favorable for clause length in arguments and words. 2) MAL holds reasonably well between the size of the clause in phrases and of the phrase in words under some conditions, i.e., within a specific range of construct size and text genres. 3) To summarize, the phrase, a notion proposed by Mačutek, Ján, Radek Čech & Jiří Milička. 2017. Menzerath-Altmann law in syntactic dependency structure. In Proceedings of the fourth international conference on dependency linguistics (Depling 2017), 100–107 under the theoretical framework of dependency grammar, is the most appropriate one to be the neighboring unit of the clause among the three measurement units. These findings may shed light on the features of syntactic structures and lead to a better understanding of the human language system.

In this study, copper oxide (CuO) specimens were successfully prepared by the hydrothermal process at altered calcination temperatures; 350, 450, and 550°C. The synthesized samples were analyzed through X-ray powder diffraction (XRD), scanning electron microscope (SEM), Raman, Fourier-transform infrared spectroscopy (FTIR), and UV-Vis spectroscopy to analyze the impact of calcination temperature on the structural, morphological, vibration spectra, functional group, and optical properties of CuO for optoelectronic device applications. XRD confirms the pure single-phase monoclinic structure of synthesized samples with no impurity phases and has good crystallinity with the development in calcination temperature. The average crystalline size, lattice constant, and porosity were found in the range of 3.98–5.06 nm;a= 3.4357 Å,b= 3.9902 Å,c= 4.8977 Å – a= 3.0573 Å,b= 3.9573 Å,c= 4.6892 Å; and 3.37–1.03%, respectively. SEM exhibited a variation in morphology by increasing calcination temperature. Raman spectra revealed that the CuO sample calcinated at 550°C with a stone-like shape having a large grain size of 3.25 μm exhibited that Raman peak intensity and the multiphonon band became stronger and sharper and exhibited higher intensity compared to the samples calcinated at 350 and 450°C. FTIR spectra confirmed that these synthesized specimens exhibited the peaks associated with the typical stretching vibrations of the Cu–O bond between 400 and 500 cm−1exhibiting the formation of CuO. The energy bandgap was slightly reduced from 1.61 to 1.43 eV with the increase in the calcination temperature. The optical studies revealed that the calcination temperature of 550°C improves the optical properties of CuO by tuning its optical bandgap. The modified structural, morphological, and optical characteristics of the prepared CuO samples make them an appropriate candidate for optoelectronic device applications.
Abundant exact solutions of higher-order dispersion variable coefficient KdV equation
Authors: Zhao Zhen , Pang Jing
Published: September 2022

In this article, various exact solutions of the fifth-order variable coefficient KdV equation with higher-order dispersion term are studied. Because of the complexity of the exact solution of the variable coefficient t, it has a certain influence on the tension waves at the fluid interface on the gravity surface. First, the bilinear KdV equation is derived by using the Hirota bilinear method, and four mixed solutions consisting of positive quartic function, quadratic function, exponential function, and hyperbolic function are constructed. Second, the linear superposition principle is used to obtain the resonance multisoliton solution, and two cases are taken as examples to illustrate the study of resonance multi soliton solution. In addition, 3D images and contour images are drawn by mathematical symbol calculation and appropriate parameters, and the process of tension fluctuation is vividly explained by physical phenomena. The results obtained greatly expand the exact solution of the KdV equation in the existing literature and enable us to understand nonlinear dynamical systems more deeply.

Published: September 2022

Arcobacter spp. are food-borne and zoonotic entero-pathogens. Obtaining information in relation to antimicrobial resistance helps us for utilisation of an appropriate agent for the treatment of Arcobacter infections. This study aimed to investigate the prevalence, antimicrobial resistance and virulence factors in animal raw meat in Iran. The samples were collected from cattle (n=80), sheep (n=80), goats (n=80), camels (n=80), and buffaloes (n=60) from Khuzestan (n=110), Isfahan (n=80), Gilan (n=110) and Chaharmahal and Bakhtiari (n=80) provinces. Arcobacter isolates of meat samples were isolated, investigated by PCR method. The antibiotic resistance was also investigated. All isolates were screened for 6 virulence genes: cadF, ciaB, cj1349, Mvin, pldA and tlyA by PCR assays. The results showed that the prevalence of Arcobacter species had no significant difference among provinces and animals (P>0.05), so that positive samples were 1.25%, 1.25%, and 0.9% in Isfafhan, Chaharmahal and Bakhtiari, and Gilan, respectively. Virulence genes were observed for A. butzleri species (n=3, 100%). The results showed that Arcobacter spp. were resistant to streptomycin (100%), tetracycline (100%) and vancomycin (100%), but were susceptible to azithromycin (33.33%). In sum, the different regions of the Iran had a relative incidence of 1% for Arcobacter spp. The species showed a resistance of 100% for streptomycin, tetracycline and vancomycin. These findings could help to identify Arcobacter spp. and select the best agent against infection in case of Arcobacter infection in animals.

Assessment of water quality variations due to operation of wastewater treatment plant in Ca Mau city
Authors: Ngo Tra Mai , Thi Thanh Hang Phan
Published: September 2022

The wastewater treatment plant (WWTP) in Ca Mau city, which is being planned for construction, will be responsible for treating domestic wastewater with a capacity of 8,000 m3/day. After being treated by the physic-biological method, the plant’s wastewater will be discharged into the Thong Nhat canal and the Tac Thu river. As a result, this article applies the MIKE21 model to calculate the range, the distance, and the concentration of typical pollutants for domestic wastewater, including TSS, BOD5, NH4+, and total Coliforms in the dry season, to provide evidence for water resource management following the plant’s construction. Two scenarios were established; in scenario 1 (S1), the WWTP is being operated inefficiently, and the wastewater has not been treated up to standards. Maximum calculation in case the processing performance = 0; in scenario 2 (S2), the WWTP is being operated efficiently. The concentration of 4 components in wastewater is lower than the critical value of QCVN 14:2008/BTNMT (column B, K = 1). The results show that the waste source will highly affect the water in the Thong Nhat canal both downstream and upstream due to the irregular semi-diurnal tide regime in case of the plant experiences problems (S1). In the case of the stable operation plant (S2), the pollutant concentrations at all positions will be lower than the critical value of QCVN 08-MT:2015/BTNMT (column B1) except for the TSS. Concentration variation is evident over time and distance: after about 1 hour and about 1 km from the source, the concentration of pollutants reaches the maximum value, then gradually decreases and ends at about 4 km after 7 hours.

Authors: Martins Maria Helena Venâncio , Moriña Anabel
Published: September 2022

This paper explores resilience factors identified in students with disabilities at a Portuguese public university. This research employs a mixed approach using qualitative and quantitative methods. For this, we used a retrospective, multiple case study design, and individual interviews were conducted with students with disabilities. We conclude that resilience, self-esteem, family support, subjective well-being and psychological well-being are protective factors that contribute to a good adaptation and better inclusion in higher education. Accessibility conditions on campus continue to present barriers that hinder mobility and the students’ academic experience. Besides their resilience, it is noteworthy to mention the persistence and dedication these students reveal, continuing to struggle every day to make their dreams come true, facing a daily routine that is not always easy.
WORLD ANTHROPOLOGICAL PERSPECTIVES ON ECONOMIC NATIONALISMS*
Authors: Kingsolver Ann E. , Pandey Annapurna Devi , Onto Gustavo , Opesen Chris C. , Appel Hannah
Published: September 2022

Abstract As rising numbers of national governments promote economic nationalist policies and the withdrawal from (or renegotiation of) global political and economic relationships, the impossibility of disconnecting from global circulations is illustrated by the traveling discourse of economic nationalism itself, although conceptualized and implemented quite differently as refracted through specific historical and political contexts. Drawing on the possibilities of world anthropologies, the authors build connected analyses of the lived effects and contradictions of economic nationalist policies through their ethnographic examples from Brazil, India, Uganda, and the US. In comparatively analyzing these contexts, the authors emphasize the plural, transhistorical, transnational, gendered, and contested nature of economic nationalist policies and discourses worldwide, pointing to the need for further empirical investigations into diverse understandings and political deployments of economic nationalist projects.

Resumo O artigo procura fazer um duplo balanço da Semana de Arte Moderna e da Independência. Mais do que isso, pretende explorar livremente a relação entre os dois acontecimentos, em uma perspectiva que já pode ser chamada de longa duração. Para realizar o balanço, são utilizados como materiais especialmente trabalhos sobre o pensamento político e social brasileiro. Procura-se, sobretudo, esboçar uma interpretação do modernismo brasileiro, na qual é ressaltado, em dissonância com o que pode ser chamado de uma espécie de sensibilidade sobre 1922 que tem ganhado força, seu caráter fundamentalmente democrático. De maneira complementar, para que o argumento ganhe corpo, mobiliza-se uma interpretação da Independência, identificada com Caio Prado Júnior e Florestan Fernandes, que chama a atenção para as deficiências democráticas de 1822, que marcam o país desde então. Relaciona-se, a partir daí, em sentido oposto, a orientação democrática de 1922.
MOCIDADE REDIVIVA: MÁRIO DE ANDRADE, OS JOVENS MINEIROS DE 1920 E O SELF MODERNISTA
Authors: Bittencourt Andre , Hoelz Maurício
Published: September 2022

Resumo O artigo analisa a relação entre Mário de Andrade e duas gerações de jovens escritores mineiros nos anos 1920. Tomando como material empírico da pesquisa o periódico A Revista e a correspondência de Mário com Carlos Drummond de Andrade, Francisco Martins de Almeida e Rosário Fusco, dentre outros, procurou-se qualificar a importância da categoria “mocidade” e como nela está implicada uma nova forma de ver a cultura e a as relações sociais. A hipótese do artigo é de que a correspondência de Mário com os rapazes mineiros, apesar de diversa, foi um mecanismo central para a modelagem de um self modernista, este fundamental para a construção do modernismo como movimento cultural, cujos valores e ideias teriam a mocidade como portadora social.

RC beams with rectangular openings in case of fire

Published: September 2022

Abstract Openings in reinforced concrete (RC) beams may be required due to building installations (electrical, water, etc.). They weaken its cross-sectional area and, in case of fire, can increase the thermal field of the structure. NBR 15200 does not consider this. The paper evaluated the influence of rectangular openings on the Fire Resistance Rating (FRR) of RC beams by the Simplified Method of NBR 15200. This method combines a non-linear thermal analysis (isotherms) with the evaluation of the flexural strength of the beams using a manual design calculation method. The thermal field were obtained by a thermal model solved by finite element analysis (FEA) with Abaqus software. Thermal parameters of NBR 15200 were used. This FRR was compared with equivalent beams without openings solved by the Tabular Method of NBR 15200. Twelve 60 cm high beams with different widths and dimensions of openings were studied. Beams with openings had a FRR up to 60 min lower than the equivalent beam without openings. The larger the size of the rectangular opening, the greater the mechanical degradation of the beam in fire. NBR 15200 Tabular Method proved to be unsafe in this case. Prescriptions for beams with openings must be shown in NBR 15200.
The Influence of k-Dependence on the Complexity of Planning
Authors: Gimenez Omer , Jonsson Anders
Published: September 2022

A planning problem is k-dependent if each action has at most k pre-conditions on variables unaffected by the action. This concept is well-founded since k is a constant for all but a few of the standard planning domains, and is known to have implications for tractability. In this paper, we present several new complexity results for P(k), the class of k-dependent planning problems with binary variables and polytree causal graphs. The problem of plan generation for P(k) is equivalent to determining how many times each variable can change. Using this fact, we present a polytime plan generation algorithm for P(2) and P(3). For constant k > 3, we introduce and use the notion of a cover to find conditions under which plan generation for P(k) is polynomial.
Pervasive Model Adaptation: The Integration of Planning and Information Gathering in Dynamic Production Systems
Authors: Liu Juan , Kuhn Lukas , De Kleer Johan , Zhou Rong
Published: September 2022

Model-based planning often presumes a static system model, while in a practice physical system may evolve or drift over time. This paper proposes the idea of pervasive model adaptation in a production system, where the model is dynamically updated using observation of production output. The core idea is the interplay between model adaptation and production planning. We seek plans which simultaneously serve the goals of achieving high productivity for production, and information gathering for model adaptation. We use a modular printing example to illustrate issues such as formulation of the information criterion and search strategy for informative plans. The idea of pervasive adaptation can be further extended to improve long term productivity in production systems.
Forward Constraint-Based Algorithms for Anytime Planning
Authors: Pralet Cédric , Verfaillie Gérard
Published: September 2022

This paper presents a generic anytime forward-search constraint-based algorithm for solving planning problems expressed in the CNT framework (Constraint Network on Timelines). It is generic because it allows many kinds of search to be covered, from complete tree search to greedy search. It is anytime because some parameter settings, together with domain-specific knowledge, allow high quality plans to be produced very quickly and to be further improved. It is forward because it systematically considers the decisions to be made in a chronological order. It is finally constraint-based because it is built on top of the CNT framework which is an extension of the CSP framework able to model discrete event dynamic systems and because it is implemented on top of the Choco constraint programming tool from which it inherits all the constraint handling machinery. Experimental comparisons are made in terms of quality profile with other domain-dependent and domain-independent planners.
Improved Local Search for Job Shop Scheduling with uncertain Durations
Authors: Gonzalez-Rodriguez Ines , Vela Camino , Puente Jorge , Hernandez-Arauzo Alejandro
Published: September 2022

This paper is concerned with local search methods to solve job shop scheduling problems with uncertain durations modelled as fuzzy numbers. Based on a neighbourhood structure from the literature, a reduced set of moves and the consequent structure are defined. Theoretical results show that the proposed neighbourhood contains all the improving solutions from the original neighbourhood and provide a sufficient condition for optimality. Additionally, a makespan lower bound is proposed which can be used to discard neighbours. Experimental results illustrate the good performance of both proposals, which considerably reduce the computational load of the local search, as well as a synergy effect when they are simultaneously used.
Extending the Use of Inference in Temporal Planning as Forwards Search
Authors: Coles Amanda , Coles Andrew , Fox Maria , Long Derek
Published: September 2022

PDDL 2.1 supports modelling of complex temporal planning domains in which solutions must exploit concurrency. Few existing temporal planners can solve problems that require concurrency and those that do typically pay a performance price to deploy reasoning machinery that is not always required. In this paper we show how to improve the performance of forward-search planners that attempt to solve the full temporal planning problem, both by narrowing the use of the concurrency machinery to situations that demand it and also by improving the power of inference to prune redundant branches of the search space for common patterns of interaction in temporal domains that do require concurrency. Results illustrate the effectiveness of our ideas in improving the efficiency of a temporal planner that can solve problems with required concurrency, both in domains that exploit this ability and in those that do not.
Suboptimal and Anytime Heuristic Search on Multi-Core Machines
Authors: Burns Ethan , Lemons Seth , Ruml Wheeler , Zhou Rong
Published: September 2022

In order to scale with modern processors, planning algorithms must become multi-threaded. In this paper, we present parallel shared-memory algorithms for two problems that underlie many planning systems: suboptimal and anytime heuristic search. We extend a recently-proposed approach for parallel optimal search to the suboptimal case, providing two new pruning rules for bounded suboptimal search. We also show how this new approach can be used for parallel anytime search. Using temporal logic, we prove the correctness of our framework, and in an empirical comparison on STRIPS planning, grid pathfinding, and sliding tile puzzle problems using an 8-core machine, we show that it yields faster search performance than previous proposals.
LPRPG-P: Relaxed Plan Heuristics for Planning with Preferences
Authors: Coles Amanda , Coles Andrew
Published: September 2022

In this paper we present a planner, LPRPG-P, capable of reasoning with the non-temporal subset of PDDL 3 preferences. Our focus is on computation of relaxed plan based heuristics that effectively guide a planner towards good solutions satisfying preferences. We build on the planner LPRPG, a hybrid relaxed planning graph (RPG)--linear programming (LP) approach. We make extensions to the RPG to reason with propositional preferences, and to the LP to reason with numeric preferences. LPRPG-P is the first planner with direct guidance for numeric preference satisfaction, exploiting the strong numeric reasoning of the LP. We introduce an anytime search approach for use with our new heuristic, and present results showing that LPRPG-P extends the state of the art in domain-independent planning with preferences.
When Optimal Is Just Not Good Enough: Learning Fast Informative Action Cost Partitionings
Authors: Karpas Erez , Katz Michael , Markovitch Shaul
Published: September 2022

Several recent heuristics for domain independent planning adopt some action cost partitioning scheme to derive admissible heuristic estimates. Given a state, two methods for obtaining an action cost partitioning have been proposed: optimal cost partitioning, which results in the best possible heuristic estimate for that state, but requires a substantial computational effort, and ad-hoc (uniform) cost partitioning, which is much faster, but is usually less informative. These two methods represent almost opposite points in the tradeoff between heuristic accuracy and heuristic computation time. One compromise that has been proposed between these two is using an optimal cost partitioning for the initial state to evaluate all states. In this paper, we propose a novel method for deriving a fast, informative cost-partitioning scheme, that is based on computing optimal action cost partitionings for a small set of states, and using these to derive heuristic estimates for all states. Our method provides greater control over the accuracy/computation-time tradeoff, which, as our empirical evaluation shows, can result in better performance.
Visual Programming of Plan Dynamics Using Constraints and Landmarks

Published: September 2022

In recent years, there has been considerable interest in the use of planning techniques in the area of new media. Many traditional planning notions no longer apply in the context of these applications. In particular, it can be difficult to answer the important question of what constitutes a good plan for the domain, but there is an emerging consensus that plan dynamics play an important role. As a consequence, it is important to support representation of such aspects. Our solution is to introduce a meta-level of representation that is an abstraction of the domain with respect to both time and causality, and to develop a visual representation of this in the form of a narrative arc. This visual representation can then be used in a visual programming approach to the exploration and specification of plan dynamics. In the paper we outline this approach to meta-level representation using constraints along with the visual programming interface we have developed. We illustrate the approach with examples of visual programming in the development of an interactive entertainment system based on Shakespeare's play ``The Merchant of Venice''
