An analysis of the equilibrium strategies for route-choosing customers in a two-station queueing system

We investigate a two-station queueing system where strategic customers must be sequentially serviced at both stations. We prove that an established property — that the distribution of the total time spent in a two-station system is independent of the chosen route when services times are exponentially distributed — is not a general one by providing a counterexample with deterministic service times. In doing so, we also prove a concomitant property — that any routing strategy is an equilibrium — is peculiar to a system with a particular assumption of an exponential service time distribution. Using simulations, we show that — depending on the distribution of service times — there can be (1) cases with three equilibria, (2) cases with one pure strategy equilibrium, and (3) cases with one mixed strategy equilibrium.

Measuring the adoption of internet and communication technologies among practitioners in routine disability services: a stepped inclusive approach

Purpose Existing measurements of the use of information and communication technologies (ICTs) among practitioners in disability services often treat ICT adoption as a monolithic concept, overlooking its multifaceted nature within the disability field. This study introduces a stepped, inclusive approach to capturing this complexity, elucidating disparities in the utilization of various ICT dimensions, the present vs. anticipated use, and variations among different clinical-demographic groups. Materials and methods A cross-sectional survey was conducted in Hong Kong, gathering valid data from 324 practitioners spanning diverse disciplines and disability services. Results Data analysis produced a three-factor model categorizing ICT tools into (1) information and communication tools, (2) screening and monitoring tools, and (3) treatment and rehabilitation tools. The first category was identified as the predominant ICT utilized currently, with significant projected growth in the latter two categories’ usage. Variances in current ICT adoption were influenced by practitioners’ roles, clientele, positions, affiliating agencies, and educational attainments. Conclusions This research provides a deeper understanding of the key dimensions of ICT adoption within disability services. It underscores the importance of devising specific and customized strategies for the effective integration of ICTs, ensuring a more tailored approach to meeting the unique demands of the disability field.

포스트 팬데믹에서 백화점 화장품 소비자 구매행동 변화가 백화점 화장품 판매직의 조직몰입에 미치는 영향

Since the onset of the pandemic, there have been noticeable shifts in consumers’ purchase behaviors. These changes have had a significant impact on sales workers, especially in the department store cosmetics sector. Amidst these circumstances, cosmetic sales workers have been encountering challenges stemming from the shifts in consumers' purchasing behaviors. In this context, this study aimed to investigate the impact of sales workers' perceptions of these changes in consumers' purchasing behaviors after the pandemic on organizational commitment among department store cosmetics sales workers. Additionally, it sought to uncover the relationships that could influence these effects through the mediating role of cognitive flexibility. To accomplish this, a questionnaire survey was administered to 555 department store cosmetics sales workers between June 20 and July 20, 2023. To ensure the validity of the study, a research model was tested, using SPSS WIN 25.0. This study investigated whether changes in consumers' buying behavior (independent variable) affected department store cosmetics sales workers' organizational commitment (dependent variable), and whether cognitive flexibility played a mediating role in this relationship. The study found that shifts in consumers' purchase behavior had a statistically significant negative impact on organizational commitment. However, cognitive flexibility was identified as a mediator in the relationship between changes in consumers' purchase behavior and sales workers' organizational commitment. In other words, as sales workers become less aware of changes in consumers' purchase patterns and enhance their cognitive flexibility, their organizational commitment increases. These findings are expected to assist cosmetics businesses in swiftly adapting to new environments, while also enabling sales workers to enhance their organizational commitment by developing cognitive flexibility. Additionally, in the post-pandemic era, it is anticipated that cosmetics businesses will remain competitive and continue to grow by implementing customized strategies and leveraging the competence of their sales workers in response to rapidly changing business environments.

Impact of Postprocedural Graft Flow on Outcomes Following Chronic Total Occlusion Intervention in Postcoronary Artery Bypass Graft Patients: A Detailed Angiographic Analysis

Chronic total occlusions (CTOs) are frequent in patients with previous coronary artery bypass graft (CABG) surgery. Percutaneous coronary intervention (PCI) is the usual revascularization strategy. Whether or not the presence of a graft on a CTO vessel and post-PCI graft patency impacts outcomes after CTO-PCI is unknown. We sought to evaluate the impact of post-PCI graft patency on the durability of CTO-PCI. In total, 259 patients with previous CABG who underwent CTO-PCI in 12 international centers in 2019 to 2023 were categorized into "grafted" and "ungrafted" groups based on the presence of graft on a CTO vessel. The grafted group was subdivided into "graft-occluded" and "graft-patent" groups, depending on graft patency. The primary end points were (1) technical success rate, (2) target vessel failure, and (3) CTO failure rates at 1 year. CTO failure was defined as target vessel revascularization and/or significant in-stent restenosis. A total of 199 patients (77%) were in the grafted group. Grafted CTOs showed higher complexity and lower technical success rates (70% vs 80%, p = 0.004) than nongrafted CTOs. Of the grafted CTOs, 140 (70%) were in the grafted-occluded group and 59 (30%) were in the grafted-patent group. The technical success was lower in the former group (65% vs 81%, p = 0.022). An occluded graft was an independent predictor of technical failure (odds ratio 2.04, 95% confidence interval 1.03 to 4.76, p = 0.049) and persistent post-PCI graft patency was a strong independent predictor of CTO failure at 1 year (hazard ratio 5.6, 95% confidence interval 1.2 to 27.5, log-rank p = 0.033). In conclusion, in patients with previous CABG who underwent CTO-PCI, post-PCI graft patency was a significant predictor of CTO failure.

Designable immobilization of D-allulose 3-epimerase on bimetallic organic frameworks based on metal ion compatibility for enhanced D-allulose production

D-allulose, a low-calorie rare sugar catalyzed by D-allulose 3-epimerase (DAE), is highly sought after for its potential health benefits. However, poor reusability and stability of DAE limited its popularization in industrial applications. Although metal-organic frameworks (MOFs) offer a promising enzyme platform for enzyme immobilization, developing customized strategies for MOF immobilization of enzymes remains challenging. In this study, we introduce a designable strategy involving the construction of bimetal-organic frameworks (ZnCo-MOF) based on metal ions compatibility. The DAE@MOFs materials were prepared and characterized, and the immobilization of DAE and the enzymatic characteristics of the MOF-immobilized DAE were subsequently evaluated. Remarkably, DAE@ZnCo-MOF exhibited superior recyclability which could maintain 95 % relative activity after 8 consecutive cycles. The storage stability is significantly improved compared to the free form, with a relative activity of 116 % remaining after 30 days. Molecular docking was also employed to investigate the interaction between DAE and the components of MOFs synthesis. The results demonstrate that the DAE@ZnCo-MOF exhibited enhanced catalytic efficiency and increased stability. This study introduces a viable and adaptable MOF-based immobilization strategy for enzymes, which holds the potential to expand the implementation of enzyme biocatalysts in a multitude of disciplines.

Customised product design optimisation considering module synergy effects and expert preferences

ABSTRACT Fierce marketing competition and varied customer requirements on products make a lot of companies transfer to the customisation strategy. However, customers may be overwhelmed by the vast assortment of products and options. This paper proposes a methodology aimed at optimising the range of customised product varieties considering synergy effects of modules and preferences of experts. The methodology outlines key steps required for a successful customised product configuration. Firstly, a questionnaire based on the Kano model is designed to identify customer preferences for product module customisation. The potential customers can be segmented based on the distance among their multidimensional preferences. Secondly, within each segmented market, the customer satisfaction function that considers module synergies is established using the quantified Kano model and coefficient matrix. Thirdly, the cost function that considers experts' preferences is established based on the prospect theory. Finally, a bi-objective optimisation model is formulated to maximise customer satisfaction and minimise cost under technical constraints. Pareto solutions are obtained by solving the model with the non-dominated sorting genetic algorithm II (NSGA-II). Modules and attributes available to customers can be determined by the solutions. An illustrative example of modular laptop computers confirms the methodology's effectiveness in optimising product configuration.

Importance-performance dynamics and willingness to pay in coastal areas for climate-adaptive Marine Debris Management

This study focused on evaluating the adaptive capacity of coastal communities to manage marine debris, a critical issue intensified by the effects of human-induced climate change on the Earth's oceans. The detrimental impacts of climate change, including rising sea levels, ocean acidification, and changes in ocean currents and temperatures, pose significant threats to marine ecosystems and human societies. The study specifically investigated the factors influencing the willingness to pay (WTP) for adaptive Marine Debris Management (MDM) services. It involved diverse community groups, including passive observers, compliant followers, and eco-champions, each exhibiting unique approaches and capacities for managing marine debris. The research revealed that while passive observers and compliant followers favor asset-based programs, eco-champions are more inclined towards enhancing environmental awareness and enforcing policies. A critical methodological aspect of the study was the quantification of WTP, set at IDR 10,000 /month/household, to assess the communities' financial commitment to MDM. The study found that WTP is influenced by factors such as awareness of environmental issues, behavioral responses to regulations, beach clean-up participation, environmental education, and recycling training. Of these, income emerged as the most impactful factor on WTP, followed by education level, age, place of residence, and eco-champion classification. Furthermore, the provision of adaptive MDM services positively influenced community WTP. These findings highlight the need for MDM policymakers to develop customized strategies that address different community groups' distinct needs and priorities. The study recommends that such strategies focus on improving understanding and responsiveness to environmental regulations and providing specialized educational programs. By adopting this approach, not only can the immediate challenge of marine debris be tackled, but it can also lead to the establishment of a more sustainable and community-focused model of environmental stewardship.

Factors Affecting the Ability to Repay Debts of Corporations at Commercial Banks

This study aims to estimate the influence of these factors on the ability of corporations to repay debts at commercial banks in Vietnam, especially in Ho Chi Minh City. Moreover, this study focuses on the period from 2018 to 2022. Hence, the effects of the COVID-19 pandemic were also examined in this study. In addition, this study employs a binary logistic regression method to analyze the extent of the factors' impact on the ability of corporate customers to repay debts. The results reveal that the model includes six statistically significant factors: collateral, loan term, income, firm size, leverage, net sales, and COVID-19. Furthermore, the model can be used to forecast corporations’ ability to repay debts, which could help commercial banks plan their loan strategies for corporate customers based on the significant results of the Hosmer-Lemeshow test. The study, on the other hand, only focused on some banks in the biggest city in the south of Vietnam, so further research on the area is needed, such as over Vietnam.

Primary treatment modification strategies among older adults with advanced cancer.

1512 Background: Primary treatment modification (PTM; any change in dose or agents of the planned chemotherapy regimen from the standard guidelines) is a common therapeutic approach among older adults with advanced cancer due to their geriatric vulnerabilities. However, strategies to employ these modifications are understudied. This study compares a PTM strategy based on Geriatric Assessment (PTM-GA) intervention vs. usual care strategy based on oncologist’s impression (PTM-UC) on treatment tolerability in older adults with advanced cancer starting new chemotherapy regimens. Methods: In this subgroup analysis of the GAP 70+ study (NCT02054741; PI: Mohile), we included patients aged ≥ 70 with incurable solid tumors who initiated a chemotherapy course with PTM (n=298). For the first (PTM-GA) group, PTM was guided by GA results and recommendations while for the second (PTM-UC) group, PTM was guided by the treating oncologist's estimate only. Tolerability outcomes were assessed within 3 months of treatment and included: 1) any grade 3-5 clinician-rated toxicity according to National Cancer Institute Common Toxicity Criteria; 2) subsequent dose reduction; 3) Activity of Daily Living (ADL) decline; 4) unplanned hospitalization. We used multivariable, cluster-weighted generalized estimating equations models to examine the association of PTM-GA vs. PTM-UC and outcomes adjusting for confounders. Results: Mean age was 77 years. The most common cancer types were gastrointestinal (37%) followed by lung cancer (26%). PTM-GA versus PTM-UC was associated with reduced risk of grade 3-5 toxicity (relative risk (RR)= 0.77, 95% CI, 0.61- 0.90) and subsequent dose reduction (RR, 0.46; 95% CI, 0.29-0.73). Point estimates suggest that patients with PTM-GA may have a lower risk of unplanned hospitalization but results did not reach statistical significance (RR, 0.69; 95% CI, 0.46–1.02). PTM-GA vs. PTM-UC was not associated with ADL decline (RR, 1.05; 95% CI, 0.74–1.49). Conclusions: Older patients with advanced cancer who had PTM guided by GA recommendations had improved treatment tolerability compared to those who PTM based on oncologist’s estimate only. Integrating GA into treatment dosing decisions may lead to improved outcomes in this vulnerable population.

Equilibrium balking behavior of customers and regulation measures in a multi-server queue with threshold policy

ABSTRACT The equilibrium balking behavior of customers and some effective regulation measures in a multi-server queueing system with a threshold policy are mostly investigated in this paper. We consider four information levels: entirely visible, nearly visible, nearly invisible and entirely invisible. For each case, we compare the equilibrium and socially optimal balking strategies of customers, formulate pricing strategy and analyze the revenue of the system manager. It is found that no matter what information level, there always exist the optimal thresholds that maximize the optimal social welfare and the system manager’s revenue, respectively. Moreover, how much information the customers know has influence on the optimal social welfare. Such findings can provide guidance for the social planner to formulate pricing strategies, make appropriate threshold policies and decide what information should be disclosed to customers to improve the optimal social welfare.

To Calm and to Commend: Veterans' Musical Preferences Anticipating End of Life.

Since World War 1, physicians have noted the calming effects of music for military personnel experiencing "shell shock," Post Traumatic Stress Disorder (PTSD), or stress. Researchers have documented that stress or PTSD-like symptoms re-emerge for veterans at the end of life, triggered by hospital-like settings, co-occurring conditions, and debilitation. Dying veterans also face integration of their service and combat experiences into summations of their lives. In response, there has been a national movement for bedside ceremonies, often with music, to honor veterans. The project elicited veterans' musical preferences for calming and for music for honor services, using non-hospitalized veterans as surrogates for veterans in hospice. Respondent-driven sampling protected confidentiality and likely resulted in participants being representative of US veterans in terms of ethnicity, gender, and military branch. Recruitment materials contained all elements of informed consent, with consent collected in the introduction to the online survey. The survey had embedded links to musical performances, as well as write-in musical choices, and allowed US veterans from the Army, Air Force, Marines, and Navy to note their preferences both for music that was calming and music to be used in honor ceremonies. Online queries also asked about stress during service, usual coping strategies for stress, and current or past symptoms of PTSD. Links to hot lines were provided. The study was approved by the University of Arizona Institutional Review Board. Listening to music was the most prevalent of the 20 coping mechanisms for stress in this sample of 30 veterans. Musical preferences were stable across age groups. For calming, music at resting heartbeat rhythms was chosen. Music from early adulthood or from the timelessness of the classics was selected most often. Modern music with lyrics has themes of duty, affirmation, gratitude, and relief. The nearly universal soothing effects of lullabies were recognized. For music for honor ceremonies, desires were often independent of the military branch. Patriotic songs, or songs recognizing multiple service branches, or with themes of peace and affirmation were more often chosen than music from a particular service branch. Listening to music is a frequent coping strategy for veterans. While themes representing classical music choices are readily available in anthologies, other music chosen by this sample is not; the veterans' preferred music is rarely found in compilations of popular, movie, and TV music. Hospice and hospital intakes that document and communicate veterans' musical preferences to music therapists and therapeutic musicians may better support service men and women. Further research may examine veterans' preference for live or recorded music at end of life given the importance of meaning-making and the presence of others documented in the literature.

Strategic Behavior and Optimal Inventory Level in a Make-to-Stock Queueing System with Retrial Customers

In this article, we consider a make-to-stock queueing system with retrial customers. Upon their arrival, customers make a decision to either join the system or not based on a reward–cost function. If customers join the retrial queue, they become repeat customers. Each repeat customer repeats their demand after an exponential amount of time until they have been successfully served. We explore the equilibrium strategies of customers in both the almost observable and unobservable cases. Furthermore, we also analyze the expected costs of the entire system based on the customers’ behavior in these two cases. Additionally, we determine the optimal inventory levels in both cases through numerical experiments.

Abstract PO1-06-01: Clinical Efficacy of Tumor Organoid-Guided Cancer Therapy for Locally Advanced Unresectable or Metastatic Breast Cancer

Abstract Purpose: Patient-derived organoids (PDOs) may facilitate treatment selection, but the feasibility of using breast cancer PDOs to guide personalized treatment in clinical practice has not been fully investigated. This study aimed to assess the clinical efficacy of treatment guided by PDO drug sensitivity tests (OGT) versus treatment of physician’s choice (TPC) in patients with locally advanced unresectable or metastatic breast cancer (MBC) and to explore the potential of PDOs to reveal mechanisms underlying treatment resistance. Methods: Patients diagnosed with MBC were recruited between January 2020 and August 2022. PDOs were established from biopsies specimens or malignant effusion samples. The efficacy of customized drug panels was determined by measuring cell mortality after drug exposure. Patients receiving OGT were matched 1:2 by nearest neighbor propensity scores with patients receiving TPC. The primary clinical outcome was progression-free survival. Secondary outcomes included objective response rate and disease control rate. Targeted gene sequencing and pathway enrichment analysis were performed. Results: 46 PDOs (46 of 51, 90.2%) were generated from 45 MBC patients. PDO drug screening showed an accuracy of 81.1% (95% CI 67.6%-91.9%) in predicting patients' clinical responses. 36 OGT patients were matched to 69 TPC patients. OGT was associated with prolonged median progression-free survival (11.0 months vs 5.0 months; unadjusted hazard ratio 0.53 [95% CI 0.33-0.85]; P=0.01) and improved disease control (88.9% vs 63.8%; unadjusted odd ratio 4.26 [1.44-18.62]) compared with TPC. The objective response rate of both groups was similar. Pathway enrichment analysis uncovered differentially modulated pathways implicated in DNA repair and transcriptional regulation in patients less sensitive to capecitabine/gemcitabine, and pathways associated with cell cycle regulation in patients less sensitive to palbociclib. Conclusions: MBC patients treated with OGT were associated with superior progression-free survival and disease control compared with TPC. PDO-based functional precision medicine is a feasible strategy for treatment optimization and customization in MBC and may enhance our understanding of therapeutic resistance.

Security dissipative control for interval type‐2 fuzzy hidden Markovian jump systems under event‐triggered scheme

AbstractThis article presents a new design approach for resilient fault‐tolerant event‐triggered (ET) based security control of Markovian jump nonlinear systems (MJNSs) in the presence of nonperiodic denial‐of‐service (DoS) attacks. The approach is developed based on interval type‐2 (IT‐2) fuzzy models of the plant. The state error produced by data packet loss is turned into a parameter in the proposed ET condition during nonperiodic DoS attacks. The uncertain triggering variable is considered in the resilient fault‐tolerant ET condition for the MJNSs. In contrast to the usual strategy, the fault‐tolerant ET strategy is designed to send the required data packets to the controller during nonperiodic DoS attacks, which significantly contributes to the minimization of performance loss. Dissipative, passive, and ‐control schemes are all covered in a unifying framework by using a generalized performance index. Plant and controller modes are considered under mismatched membership functions to regulate asynchronous phenomena. Sufficient conditions depending on the membership functions that guarantee the stability of the closed‐loop system are derived. Finally, two numerical examples are provided to demonstrate the effectiveness of the proposed approach.

This review aims to present current advances in the use of BP nanoparticles in OS therapy, including the synthesis of BP nanoparticles, properties of BP nanoparticles, types of BP nanoparticles, and modification strategies for BP nanoparticles. In addition, we have discussed comprehensively the application of BP in OS therapy, including single, dual, and multimodal synergistic OS therapies, as well as studies about bone regeneration and antibacterial properties. Finally, we have summarized the conclusions, limitations and perspectives of BP nanoparticles for OS therapy.

Consumer ethnocentrism, cosmopolitanism, product judgment, and foreign product purchase intention: An empirical study in Vietnam

This study aims to determine the relationship between consumer ethnocentrism, consumer cosmopolitanism, imported product judgment, and foreign product purchase intention in Vietnam. This paper tries to present its results empirically, which might be helpful in preparing a strategy for Vietnamese customers’ international purchasing behavior to increase competition at retail companies in Vietnam. It uses a questionnaire with a purposive random sampling of 311 customers in Vietnam. Analysis was conducted through a quantitative descriptive analysis, measurement of variable dimensions on the questionnaire using a seven-point Likert scale, and partial least squares structural equation modeling (PLS-SEM) to test the hypotheses. This study found that imported product judgment, consumer cosmopolitanism, social influence, and perceived behavioral control positively influence foreign product purchase intention, whereas customer ethnocentrism has a negative impact on that intention. The association between consumer cosmopolitanism and foreign product purchase intention is mediated by imported product evaluation and consumer ethnocentrism. At the same time, national identity does not affect consumer ethnocentrism and foreign product purchase intentions. Besides, this study offers some managerial implications for marketers in decisions linked to Vietnamese customers’ international purchasing behavior to increase competition in the domestic market. AcknowledgmentThe authors express a sincere gratitude to all the participants who generously took part in this research study.

Tailoring Garment Fit for Personalized Body Image Enhancement: Insights from Digital Fitting Research

In the context of the Fashion Apparel Industry 4.0, a transformative evolution is directed towards the Online Apparel Mass Customization (OAMC) strategy, which provides efficient and personalized apparel product solutions to consumers. A critical challenge within this customization process is the determination of sizes. While existing research addresses comfort evaluation in relation to wearer and garment fit, little attention has been given to how garment fit influences the wearer’s body image, which is also an important purchase consideration. This study investigates the impact of garment fit on the wearer’s body scale perception using quantitative research design. A digital dataset of avatars, clothed in varying sizes of T-shirts, were created for the body scale perception experiment, and an Artificial Neural Network (ANN) model was developed to predict the effect of T-shirt fit on body image. With only a small number of garments and body measurements as inputs, the ANN model can accurately predict the body scales of the clothed persons. It was found that the effect of apparel fit on body image varies depending on the wearer’s gender, body size, and shape. This model can be applied to enhance the online garment shopping experience with respect to personalized body image enhancement.
