DrugChat: Towards Enabling ChatGPT-Like Capabilities on Drug Molecule Graphs
Authors: Liang Youwei , Zhang Ruiyi , Zhang Li , Xie Pengtao
Published: May 2023

A ChatGPT-like system for drug compound analysis could be a game-changer in pharmaceutical research, accelerating drug discovery, enhancing our understanding of structure-activity relationships, guiding lead optimization, aiding drug repurposing, reducing the failure rate, and streamlining clinical trials. In this work, we make an initial attempt towards enabling ChatGPT-like capabilities on drug molecule graphs, by developing a prototype system DrugChat. DrugChat works in a similar way as ChatGPT. Users upload a compound molecule graph and ask various questions about this compound. DrugChat will answer these questions in a multi-turn, interactive manner. The DrugChat system consists of a graph neural network (GNN), a large language model (LLM), and an adaptor. The GNN takes a compound molecule graph as input and learns a representation for this graph. The adaptor transforms the graph representation produced by the GNN  into another  representation that is acceptable to the  LLM. The LLM takes the compound representation transformed by the adaptor and users' questions about this compound as inputs and generates answers. All these components are trained end-to-end.  To train DrugChat, we collected   instruction tuning datasets which contain 10,834 drug compounds and 143,517 question-answer pairs. The code and data is available at https://github.com/UCSD-AI4H/drugchat
Transient Electromagnetic Noise Suppression Based on MVMD and GMDFA
Authors: Xing Kang , Li Shiyan , Qu Zhijie , Zhang Xiaojuan
Published: May 2023

Noise suppression is an important topic in transient electromagnetic (TEM) data processing and interpretation. TEM data is a typical broadband signal, which makes it difficult to separate the signal in the whole frequency band. The conventional methods tend to process data trace by trace, ignoring the connections between channels. This paper propose a workflow based on multichannel variational mode decomposition (MVMD) and genetic multichannel detrended fluctuation analysis (GMDFA) to deal with the noise in multichannel TEM data. The proposed workflow first decomposes the 2-D TEM data into several intrinsic mode functions (IMFs) using MVMD. Then we use GMDFA to screen out the signal IMFs and remove the noise traces in signal IFMs using principal component analysis (PCA). Finally, the signal IMFs are summed up to reconstruct TEM signal. Field result shows that the proposed workflow effectively suppresses noise compared with traditional denoising methods.
Peak-Tracking BOTDA with Ternary Search
Authors: QI Di , Guan Xun , Cheng Yuansen , Chan Calvin Chun-Kit
Published: May 2023

We propose a peak-tracking BOTDA (PT-BOTDA) equipped with an efficient dynamic Brillouin frequency shift (BFS) searching scheme based on ternary search. The proposed scheme establishes a feedback loop between the chosen frequency and the corresponding Brillouin gain to reduce the required number of scanning frequencies in one measurement. We also evaluate the performance of the proposed scheme under scenarios of different searching granularities and dynamic sensing ranges. Experimental results indicate that in all situations, the proposed PT-BOTDA can achieve at least 85% reduction in the scanning frequency number with a 3-meter spatial resolution, while maintaining a convincing BFS searching accuracy under sufficient SNR condition.

Published: May 2023

In this paper, the efficiency and the quality factor (Q) of an infinitesimal loop antenna with the circumference of 0.01λ enclosed in a µ-negative (MNG) shell of 0.023λ diameter is investigated. It is demonstrated that an MNG shell can be designed to produce an electrically small system with a matched input impedance leading to total efficiency approaching unity. Simulation results show that the fractional bandwidth of significantly better than Chu limit can be obtained, especially if the material is regarded dispersionless. The calculated Q of the antenna with LL model, M model, and Z model MNG are 74.5%, 55.9%, and 37.5% of those predicted by Chu limit, respectively.

Published: May 2023

The understanding of mechanisms and conditions of plague microbe aggregation in vectors (fleas) organisms has been of interest for a long time, and, with start of biofilm research in 1990s, it got a new perspectives.
With the aim to determine the characteristics of the plague microbe aggregation in the organism the main vector in Tuva natural plague focus flea of Citellophilus tesquorum species, the data of many years of experimental studies focused on typical virulent strains of Yersinia pestis subsp. pestis were summarized and analyzed. Ectoparasites were infected and fed on long-tailed ground squirrel (Spermophilus undulatus), which is their natural host and main carrier of plague in Tuva natural plague focus. Interaction between Y. pestis and fleas were estimated using the rate of individuals with conglomerates bacterial lumps, formed during feeding, and blocks in the proventriculus foRmed during feeding and throughout the whole experiment registered in alive fleas after bloodsucking, and also using frequency of causative agent transmission to animals used for feeding.
The analysis identified factors influencing the frequency and dynamics of different Y. pestis aggregate types forming into C. tesquorum, and suggest that these processes are functional adaptation of microbe to the flea organism.

Introduction. The antigen complex of opportunistic pathogenic bacteria (ACOPB) has a protective effect against avian influenza viruses, herpes virus type 2, and other viruses that cause acute respiratory viral infections. In the context of the COVID-19 pandemic, an important task is to find out whether ACOPB has a protective effect against SARS-CoV-2.
The purpose of the study was to evaluate in vitro the ACOPB virus-inhibitory activity against the Dubrovka laboratory strain of SARS-CoV-2.
Materials and methods. The study was performed using Vero cell line CCL-81, human peripheral blood mononuclear cells (PBMCs), mouse monoclonal anti-idiotypic antibodies structurally mimicking biological effects of human interferons (IFNs), the Dubrovka laboratory strain of SARS-CoV-2. The infectivity of the virus was assessed by two methods: by virus titration using cell cultures and the limiting dilution method when the results are assessed by a cytopathic effect; the second method was a plaque assay. The in vitro virus inhibition test was performed using the cell culture susceptible to SARS-CoV-2; the mixture containing a specific dose of the virus and a two-fold dilution of ACOPB was transferred to the cell culture after the ACOPB medication had interacted with the virus at 4C for 2 hours. The ACOPB virus-inhibitory activity against SARS-CoV-2 was assessed by the functional activity of / and IFN receptors (RIFN) in human PBMCs induced in vitro by ACOPB and the ACOPB mixture with the specific dose of SARS-CoV-2. The RIFN expression level was measured by the indirect membrane immunofluorescence test.
Results. Hemagglutination assay using chicken, mouse, guinea pig, and human red blood cells was performed for detection of the SARS-CoV-2 inhibitory protein. The lysate of Vero CCL-81 cells infected with SARS-CoV-2 Dubrovka demonstrated the highest hemagglutination activity with guinea pig red blood cells and low titers of hemagglutination in the virus-containing fluid. The virus inhibition test in the Vero CCL-81 cell culture demonstrated that ACOPB inhibited 10 doses of SARS-CoV-2 Dubrovka with the titer 1 : 32, providing 100% protection of the cell culture for 8 days (the monitoring period). ACOPB induced / and RIFN expression on membranes of human PBMCs in in vitro cultures and decreased RIFN / and expression after its interaction with SARS-CoV-2 Dubrovka.
Conclusion. The experimental studies including the virus inhibition test in the cell culture susceptible to SARS-CoV-2 Dubrovka and the indirect membrane immunofluorescence assay using monoclonal anti-idiotypic antibodies mimicking IFN-like properties demonstrated that ACOPB had both an immunomodulatory and a virus-inhibitory effect.

Introduction. The incidence of healthcare-associated infections is a major public health problem worldwide, affecting all countries regardless of their economic status. The main agents of these infections are pathogens belonging to the ESKAPE group.
The aim of the study was to explore the structure, molecular and antigenic characteristics of the ESKAPE pathogens isolated from oral and anal mucosa of patients of the neonatal intensive care unit (NICU), and to assess their etiological significance in occurrence of healthcare-associated infections.
Materials and methods. Samples from a total of 49 children were tested, including 40 newborns patients of NICU at the National Hospital of Pediatrics in Hanoi. Collection and processing of biomaterial (oropharyngeal swabs, rectal swabs) and isolation of bacterial cultures were performed using conventional bacteriological methods. Mass spectrometry was used for identification of isolates. Klebsiella pneumoniae strains were analyzed using the whole-genome sequencing method.
Results. The group of gram-positive ESKAPE pathogens identified in oral mucosa was represented by isolates Enterococcus faecium and Staphylococcus aureus. The isolates of the family Enterobacteriaceae included K. pneumoniae, Escherichia coli, Enterobacter cloacae; the group of nonfermenting gram-negative bacteria was represented by Pseudomonas aeruginosa, Acinetobacter baumannii. The structure of ESKAPE pathogens persistent in anal mucosa was characterized by dominance of Enterococcus spp., E. coli, K. pneumoniae and P. aeruginosa bacteria. The whole-genome sequencing of K. pneumoniae isolates revealed 7 clusters and 8 sequence types. ST14 and ST1741 prevailed, accounting for 25%, respectively, of the total number of the studied strains. The molecular serotyping showed that by the O antigen, strains belonged mainly to serotypes O1v1, O1/ O2v2, O5; by the presence of the capsular antigen to serotypes KL2, KL104, KL60.
Conclusion. The analysis of the structure of the ESKAPE pathogens isolated from the oral and anal mucosa of patients of NICU at the National Hospital of Pediatrics in Hanoi identified etiologically significant agents of bacterial infections: S. aureus, K. pneumoniae, E. coli, E. cloacae, P. aeruginosa, A. baumannii. The molecular and genetic analysis of K. pneumoniae strains co-circulating in mucous membranes of several patients of the unit revealed their homology, thus confirming healthcare-associated contamination of children with nosocomial strains.

Introduction. Bacillus anthracis is the causative agent of anthrax, a pathogen characterized by high genetic monomorphism that complicates differentiation of strains. Thus, molecular methods for pathogen typing require the improvement.
The aim of the study. To select marker SNPs for new genetic groups of B. anthracis and to develop a method for their laboratory identification using HRM PCR.
Materials and methods. The core genome of 222 strains of B. anthracis from the GenBank database and 66 strains from the collection of pathogenic microorganisms of the Stavropol Anti-Plague Institute was aligned using the parsnp software. A dendrogram based on 7242 core genome SNPs was built in MEGA X software. The strains for validation of the HRM method included representatives of various genetic groups. The HRM PCR reaction was performed using the "Type-it HRM PCR Kit" and "KAPA HRM FAST qPCR Kit" and a Rotor Gene DNA thermocycler with HRM function. Data analysis and visualization were performed using custom scripts in the Python and R development environments.
Results and discussion. Marker SNPs for 6 genetic groups have been identified, which make it possible to determine whether strains belong to one of 7 new subclusters. Pairs of primers were selected for the loci containing them, HRM PCR parameters were optimized for discrimination of different alleles of SNP loci, and an analysis scheme was developed.
Conclusion. Thus, marker SNPs were selected to determine the genetic subclusters A.Br.CEA, A.Br.STI, A.Br.Tsiankovskii, B.Br.Europe, B.Br.Siberia, B.Br.Asia, B.Br.018, and a new laboratory method was developed for molecular subtyping of B. anthracis using HRM PCR.

Developing Task-Based Learning Materials to Improve Students’ Vocabulary Mastery Viewed from Linguistic Awareness
Authors: Naqsyabandiyah Noviana , Dehghanitafti Najmeh
Published: May 2023

Task-based language learning is an approach that highlights the use of meaningful and authentic tasks in language learning activities. In practical terms, students engage in activities or language tasks that are designed to simulate real-life situations, where they must use the language to complete the task. This approach demands that teachers design learning materials in accordance with task-based learning frameworks. Among the linguistic aspects that have been considered as having a dominant effect on language teaching is linguistic awareness. Therefore, the present study aims to develop task-based learning materials for teaching vocabulary in EFL classrooms for 11th-grade students in secondary high schools, viewed from the perspective of students’ linguistic awareness. This study employs the 4Ds (Define, Design, Develop, and Disseminate) study method. The data collection comprises two types of data, namely qualitative and quantitative data. The quantitative data are analyzed using statistical methods, while the qualitative data are analyzed using techniques such as data condensation, data display, and drawing conclusions. The outcome of this study is an English vocabulary learning material based on task-based language learning activities for high school students in Central Lombok. The task-based learning material is designed based on the syllabus, student needs, school conditions, and level of ability that the researchers have previously analyzed, ensuring that the resulting product is in line with the students' and English teachers' needs.

This paper employs computational linguistics to introduce a novel text-based measure of firm-level cyber risk exposure based on quarterly earnings conference calls of listed firms. Our quarterly measures are available for more than 13,000 firms from 85 countries over 2002-2021. We document that cyber risk exposure predicts cyber attacks, affects stock returns and profits, and is priced in the equity option market.     The cost of option protection against price, variance, and tail risks is greater for more cyber-exposed firms. Cyber risks spill over across firms and persist at the sectoral level. The geography of cyber risk exposure is well approximated by a gravity model extended with cross-border portfolio flows. Back-of-the-envelope calculations suggest that the global cost of cyber risk is over $200 billion per year.

PECULIARITIES OF ECONOMIC SECURITY OF AGRICULTURAL ENTERPRISES IN MODERN CONDITIONS: PROSPECTS AND CONNECTION WITH TECHNOLOGICAL MANAGEMENT
Authors: Vlasenko Tetiana , Dziubanovska Nataliia
Published: May 2023

The current problems of the military state of Ukraine are inherent in the decline of many branches of the economy in most regions, which also concerns the agro-food sector. Positive trends in interrelated industries have also been lost, and the emphasis on socio-economic development, in general, has been shifted. The study aims to determine the features of the process of ensuring the economic security of agricultural enterprises in modern conditions and its connection with technological management. It has been proven that it is expedient in current requirements to ensure the economic security of agrarian enterprises based on the development of technical management components. It was found that due to the long period of martial law, the economy of most agricultural enterprises is unstable, which, in turn, causes insolvency, deterioration of financial indicators, and depletion of own sources of financing. Based on the conducted research, a set of stages for assessing the state of economic security of an agricultural enterprise based on technological management is proposed. Attention is also paid to state-stimulating the creation and development of businesses based on digital technologies. Most often, such tools are reduced to measures of a tax, financial, and legal nature. A direct relationship between the economic security of the agricultural enterprise of Ukraine and its ability to respond to external and internal risks and threats has been revealed. It is noted that technology management provides management not only of the technological development of the enterprise but it also makes appropriate adjustments to the product, financial, digital, and personnel strategy. Thus, the goal of technological management is to solve the systemic tasks of managing an agricultural enterprise based on the use of new information and digital technologies while using all its available strategic resources to ensure and further increase efficiency, as well as create additional value for goods, services, and communication mechanisms.

Navigating the Path to Sustainable Oil Palm Cultivation: Addressing Nexus Challenges and Solutions
Authors: Pulighe Giuseppe
Published: May 2023

Global palm oil demand for energy, food, and chemical uses has led to a rapid expansion of tree plantations in Southeast Asia, Central Africa, Latin America and the Caribbean. This oil tree is the world’s most productive, highly profitable and traded vegetable oil crop, and the demand is expected to increase further in the near future. Nevertheless, oil palm expansion involves risks and nexus challenges. This work supports the idea that disruptive farming intensification, instead of land expansion, could scale up productivity, reducing the anthropogenic pressure on tropical forests and biodiversity losses. Findings from recent studies suggest that there is considerable scope for further yield improvements per hectare of palm oil with sustainable agronomic practices and farming intensification. Smallholder producers, agribusiness investors, civil society actors, NGOs, governments, researchers, and industry should make coordinated efforts with regulatory and support schemes and landscape design to increase yield and productivity with sustainable management practices and to achieve zero deforestation by protecting ecosystems.

Published: May 2023

Purpose: Rotation of the knee puts stress on the medial meniscus and can be a factor in the progression of knee osteoarthritis. This study aimed to investigate the rotational moment (internal rotation and external rotation) of the knee during gait and relationship between the rotational moments of the knee and other joints, including the free moment during gait. Methods: We included 18 patients with medial meniscus tears (MM group) and 10 asymptomatic participants in this study. We performed 3D gait analysis. The internal ankle, knee, and hip rotational moments as well as free moment were compared between the groups. Additionally, we investigated correlations between rotational moments of the knee and other joints during gait. Results: The maximal knee external rotation moment in the MM group was smaller than that in the asymptomatic group (p = 0.04, g = 0.76); however, there were no significant differences in the maximal internal rotation moment between the groups (p = 0.97, g = 0.02). The internal rotation (external knee external rotation) moment positively correlated with the hip internal rotation moment (p < 0.01, r = 0.69) in the MM group. Conclusions: The internal rotation (passive knee external rotation moment) did not decrease sufficiently, and correlation was observed between moments of the knee and hip in the MM group, especially during the late stance phase of gait. Reducing these abnormal moments during gait through rehabilitation may be important in patients with medial meniscus tears to prevent rapid progression of knee osteoarthritis

Building construction in Indonesia generally uses concrete. The concrete used for building structures, such as beams, generally utilizes reinforced concrete. It is very rare to see the use of prestressed concrete for building structures such as beams, especially in Batam City. This study aims to analyze the comparison between the beam structure with reinforced concrete that has been existing and prestressed concrete in the Kaliban School project. The stages in this research included prestressed concrete beam design and comparative analysis. The design of prestressed concrete beams was planned to be composite prestressed concrete blocks using the pre-tension method with a fully prestressed system, and was cast with the floor slabs and also supported during the casting period. Comparative analysis conducted by the researcher of this study was a comparison of the materials used in reinforced concrete beams and prestressed concrete beams. The results of the prestressed concrete structure design obtained a beam dimension of 200 × 400 with a diameter of 12.7 mm, in which 4 pieces were installed 125 mm below the beam. The results of the comparison analysis of the total material prices between prestressed concrete beams with dimensions of 200 × 400 and existing reinforced concrete beams with dimensions of 200 × 500 showed that prestressed concrete beams were 24.28% cheaper than reinforced concrete beams.

The literature on SWOT is characterized by a debate among academics who have identified problems and proposed solutions for the strategic management tool, yet little research to date has captured practitioners’ perspectives. Recent literature indicates that SWOT is still the most popular strategic management tool among competitive intelligence (CI) professionals. The purpose of this study is to bridge this academic-practitioner divide in the SWOT literature by conducting a cross-sectional survey that gathers practitioners’ feedback regarding whether they are experiencing the problems or employing the solutions proposed by academia. A survey was distributed via LinkedIn to collect data from CI and other business professionals who conduct SWOT in the workforce. The findings confirm that practitioners experience select problems identified by the literature. Specifically, they may have too many factors per SWOT category, may be defining factors with ambiguous and unclear words, and may not have a means for resolving conflicts when factors fall in multiple categories (e.g., opportunity and threat). The findings also indicate that practitioners may not be consistently conducting SWOT as a structured business process, as proposed in the literature. The feedback provided by CI and other business professionals aids in closing the academic-practitioner divide by more clearly identifying persistent issues with SWOT and creating valuable and actionable insights that will drive the continual improvement of this popular strategic management tool.

Both the globe and technology are growing more quickly than ever. Artificial intelligence's design and algorithm are being called into question as its deployment becomes more widespread, raising moral and ethical issues. We use artificial intelligence in a variety of industries to improve skill, service, and performance. Hence, it has both proponents and opponents. AI uses a given collection of data to derive action or knowledge. There is therefore always a chance that it will contain some inaccurate information. Since artificial intelligence is created by scientists and engineers, it will always present issues with accountability, responsibility, and system reliability. There is great potential for economic development, societal advancement, and improved human security and safety thanks to artificial intelligence.

Purpose: In marketing discipline, there is considerable interest in understanding the relationship between diverse approaches of Market Knowledge Learning and Organizational Performance, and recently, how analytics and emerging revolutionary technologies are changing this relationship. To fully apprehend this relationship it is first necessary to uncover the role of Marketing Capabilities, the management mechanism that boosts Organizational Performance using Market Knowledge. Design/methodology/approach: A new construct that embraces Analytics and Adaptive Capabilities approach (AAC) was developed to increase our comprehension of Marketing Capabilities mechanism using structural equation modeling and regressions. Findings: The model has shown an indirect-only effect of AAC using Static Marketing Capabilities as a mediator narrowing the Marketing Capabilities Gap and avoiding any tautological capabilities pitfalls. Research limitations: A deeper endogeneity test could be executed related to adaptive market approach as well it was an original preoccupation concerned to dynamics capabilities. Practical implications: It enabled managers to understand what AAC are. Additionally the results suggest precaution for headhunter because AAC needs pre-existing marketing capabilities. Social implications: It provides to managers a useful tool to assess their organizations regarding analytics in marketing realm, what makes it possible to compare with rivals and to predict the investments.Originality/value: It lies in to appraise the Marketing Capabilities management mechanism and a step by step scale developed for AAC in different industries in Brazil.

Investors increasingly non-financial factors as part of their risk analysis process and growth assessments of corporates. Machine learning (ML) models for predicting ESG scores are an extremely useful tool to help investors make more informed decisions on their portfolios. Such a tool with wide-encompassing alternative data can be useful to the investors. The use of such datasets and machine learning models for ESG ratings can continuously improve the accuracy and reliability of those models. Using machine learning algorithms to identify key drivers of ESG ratings is an effective way of improving portfolio performance. Although the current state of ESG ratings is relatively static, data collection and mapping methodologies are evolving. As more data becomes available, the noise in ESG factors will become less important.
This unique document provides a machine learning algorithm for predicting an ESG rating based on a company's financial and non-financial attributes. The financial and non-financial attributes of corporations are extracted from Moody's Orbis and Ratings from S&P. The objective here is to predict the ESG rating of companies where the ESG rating is not easily accessible. At the same time, this approach would allow investors to have a suitable framework for investments based on ESG ratings.  With the latest financial and non-financial disclosure by a corporate an ESG score can be predicted which can be used to identify its riskiness with a corresponding increase/decrease of ESG score.

The research is dealing with the necessity of substitution of zirconium powder, which was previously produced by “factory No. 1”, for the one made by “factory No. 2”. In the course of our work, which is preceding the implementation of the second kind of powder, we have found some differences in the properties of the powders of different origins. Our goal was to use the methods of studying surface, structure, chemical and phase composition and to find the cause of such discrepancy in properties and present a new way to eliminate them. The analysis of the results of the research allowed us to summarize the ways of improving the technology used on “factory No. 2” and creating the alternative ways of obtaining zirconium powder.

Coal fly ash hollow aluminosilicate microspheres (cenospheres) of stabilized composition (glass phase > 90 wt. %) were used to fabricate lutetium/yttrium-aluminosilicate microspheres as precursors of Lu-177 and Y-90 bearing β-irradiation sources applied for the selective radiation therapy of tumors. The zeolitized microspheres containing the zeolite phase NaP1 (GIS) were synthesized and their sorption properties with respect to Lu3+/Y3+ were studied. The fast heating–cooling cycle at 1200 oC in a moving bed resulted in amorphization of the zeolite component without the formation of the lutecium/yttrium crystal phase preserving the precursor spherical form.
