Shifting demographics—that is, the growing number of older adults in Canada and internationally—and intersecting climatic risks create a complex landscape of aging in place in disaster contexts. Some older adults are vulnerable due to their underlying health conditions and limited physical mobility. Yet they also exhibit resilience in a distinct manner, owing to their wealth of knowledge, wisdom, and ability to navigate adversities. This article elucidates potential avenues for promoting the involvement of older adults in disaster recovery efforts. Our intention is to recognize and foster older adult resilience and mitigate vulnerability by drawing upon insights from the study titled “In the Aftermath of the 2016 Alberta Wildfires: The Role of Social Work Practitioners and Human Service Professionals in Long-Term Disaster Recovery.” Employing a qualitative research approach, that study recruited 51 participants for semistructured interviews and focus groups. A thematic analysis of the collected data unveiled the pivotal roles played by social workers and human service practitioners in facilitating recovery from the 2016 wildfires in the research. Notably, three overarching themes emerged concerning the promotion of older adults' involvement in disaster recovery: fostering supportive relationships, building partnerships and enhancing collaboration, and addressing ongoing challenges. These findings offer valuable insights into how social work practitioners and human service professionals can effectively facilitate the engagement of older adults in disaster recovery initiatives. This article emphasizes the significance of actively promoting the participation of older adults in disaster mitigation efforts, thereby fostering greater resilience within communities.

Protected simultaneous quantum remote state preparation scheme by weak and reversal measurements in noisy environments

Chinese Physics B 2024年第2期33卷 169-177页

We discuss a quantum remote state preparation protocol by which two parties, Alice and Candy, prepare a single-qubit and a two-qubit state, respectively, at the site of the receiver Bob. The single-qubit state is known to Alice while the two-qubit state which is a non-maximally entangled Bell state is known to Candy. The three parties are connected through a single entangled state which acts as a quantum channel. We first describe the protocol in the ideal case when the entangled channel under use is in a pure state. After that, we consider the effect of amplitude damping(AD) noise on the quantum channel and describe the protocol executed through the noisy channel. The decrement of the fidelity is shown to occur with the increment in the noise parameter. This is shown by numerical computation in specific examples of the states to be created. Finally, we show that it is possible to maintain the label of fidelity to some extent and hence to decrease the effect of noise by the application of weak and reversal measurements. We also present a scheme for the generation of the five-qubit entangled resource which we require as a quantum channel. The generation scheme is run on the IBMQ platform.

Chemosensitizing Effect of Monk Fruit Extract on Human Bladder Cancer Cells

引用

Journal of Cancer Therapy 2024年第6期15卷 250-264页

作者： Sensuke Konno Jonathan Wong Andrew Penunuri Kelvin Zheng Muhammad choudhury Department of Urology New York Medical College Valhalla New York USA

The outcomes of chemotherapy have been unsatisfactory with the palpable side effects. We hypothesized that natural products might help improve chemotherapy with few side effects. Recently, we came across the bioactive extracts of monk fruit (Siraitia grosvenori) with anticancer activity. We then investigated if these extracts might have chemosensitizing effect to improve the efficacy of drugs clinically used today. Four different drugs, cisplatin (CPL), carboplatin (CBL), mitomycin C (MMC), and gemcitabine (GEM), were used in this study. Human bladder cancer T24 cells were treated with each drug itself or drug combined with either LLE or MOG (two types of monk fruit extracts). Cell viability was determined to assess anticancer effect and also explored the anticancer mechanism of such combinations, focusing on the status of glycolysis, cell cycle, and chromatin structure. Cell viability test showed that all drugs had anticancer activity, reducing cell viability, but only CPL showed the enhanced anticancer effect when combined with LLE (not with MOG). The rest of three drugs had no such effects with LLE or MOG. The CPL/LLE combination was found to disrupt glycolysis, by inhibiting hexokinase activity, resulted in the decreased ATP synthesis. This combination also blocked the cell cycle progression, due to a G1 cell cycle arrest. Moreover, the two epigenetic regulators, DNA methyltransferase and histone deacetylase, were inactivated with the combination, indicating chromatin modifications. Ultimately, these treated cells were found to undergo apoptosis. In conclusion, anticancer activity of CPL can be significantly enhanced with LLE. This chemosensitizing effect is attributed to the glycolysis inhibition, a G1 cell cycle arrest, and chromatin modifications, ultimately leading to apoptosis. Thus, certain natural products such as LLE could be used as an adjuvant agent in current chemotherapy, improving the drug efficacy but minimizing side effects.

Dynamic analysis of buried pipeline with and without barrier system subjected to underground detonation

Defence Technology（防务技术） 2023年第11期29卷 95-105页

作者： Chaidul Haque Chaudhuri Deepankar choudhury Department of Civil Engineering Indian Institute of Technology BombayMumbai400076India

Failure of pipe networks due to blast loads resulting from terrorist attacks or construction facilities, may cause economic loss, environmental pollution, source of firing or even it may lead to a disaster. The present work develops a closed-form solution of buried pipe with barrier system subjected to subsurface detonation. The solution is derived based on the concept of double-beam system. Euler Bernoulli's beams are used to simulate the buried pipe and the barrier system. Soil is idealized as viscoelastic foundation along with shear interaction between discrete Winkler springs(advanced soil model). The finite SineFourier transform is employed to solve the coupled partial differential equations. The solution is validated with past studies. A parametric study is conducted to investigate the influence of TNT charge weight, pipe material, damping ratio and TNT offset on the response of buried pipe with and without barrier system. Further a statistical analysis is carried out to get the significant soil and pipe input parameters. It is perceived that peak pipe displacements for both the cases(with and without barrier) are increases with increasing the weight of TNT charge and decreases with increasing the damping ratio and TNT offset. The deformation of pipe also varies with pipe material. Pipe safety against blast loads can be ensured by providing suitable barrier layer. The present study can be utilized in preliminary design stage as an alternative to expensive numerical analysis or field study.

A Batch Arrival Retrial Queue with Two Phases of Service and Bernoulli Vacation Schedule

引用

Acta Mathematicae Applicatae Sinica 2013年第1期29卷 15-34页

作者： Gautam choudhury kandarpa Deka Mathematical Sciences Division Institute of Advanced Study in Science and Technology Paschim Boragaon Guwahati-781035 Assam India

We consider an MX/G/1 queueing system with two phases of heterogeneous service and Bernoulli vacation schedule which operate under a linear retrial policy. In addition, each individual customer is subject to a control admission policy upon the arrival. This model generalizes both the classical M/G/1 retrial queue with arrivals in batches and a two phase batch arrival queue with a single vacation under Bernoulli vacation schedule. We will carry out an extensive stationary analysis of the system, including existence of the stationary regime, embedded Markov chain, steady state distribution of the server state and number of customer in the retrial group, stochastic decomposition and cMculation of the first moment.

The aim of this paper is to study the relationship among Minty vector variational-like inequality problem, Stampacchia vector variational-like inequality problem and vector optimization problem involving (G, α)-invex functions. Furthermore, we establish equivalence among the solutions of weak formulations of Minty vector variational-like inequality problem, Stampacchia vector variational-like inequality problem and weak efficient solution of vector optimization problem under the assumption of (G, α)-invex functions. Examples are provided to elucidate our results.
