In this paper, we study various parallelization schemes for the Variable Neighborhood Search (VNS) metaheuristic on a CPU-GPU system via OpenMP and OpenACC. A hybrid parallel VNS method is applied to recent benchmark problem instances for the multi-product dynamic lot sizing problem with product returns and recovery, which appears in reverse logistics and is known to be NP-hard. We report our findings regarding these parallelization approaches and present promising computational results. [less ▲]

This study sought to explore how research into transnational and migrant families might benefit from an account of Arab-Muslim families and their children's experiences in dynamic and conflictual contexts. Ten transnational families and their children narrate their lives as part of transnational families. From their stories and the analysis thereof, we learn how they negotiate the unique positions they occupy in transnational families and gain insight into how their cultural identities are shaped. This study also explores shared and distinctive transnational family experiences which were identified despite the small size of the sample, and emphasizes how each family and each child possesses unique resources with which they confront familial and sociocultural challenges. This study argues that social scientists, educators, and policymakers concerned about migration have much to learn from these experiences. This research also suggests that Arab-Muslim transnational families and their children's voices and lived experiences can help reframe current understandings of the effects of immigration and education systems on families in Ireland and internationally, and identifies several implications for future research and theorizing about the civic participation and engagement of children whose parents are transnational migrants.

In this paper, we study the liquid transport between particles of different sizes, as well as build a dynamic liquid bridge model to predict liquid transport between these two particles. Specifically, the drainage process of liquid adhering to two unequally-sized, non-porous wet particles is simulated using direct numerical simulations (DNS). Same as in our previous work (Wu et al., AIChE Journal, 2016, 62:1877–1897), we first provide an analytical solution of a proposed dynamic liquid bridge model. We find that such an analytical solution also describes liquid transport during collisions of unequally-sized particles very well. Finally, we show that our proposed model structure is sufficient to collapse all our direct numerical simulation data. Our model is hence able to predict liquid transport rates in size-polydisperse systems for a wide range of parameters [less ▲]

Actuellement, dans plusieurs pays européens, les immigrants de la première génération se rapprochent de l’âge de la retraite, confrontant ainsi prochainement les sociétés occidentales aux besoins émergents des futurs pensionnés immigrants et de leur famille. Au Luxembourg, à ce jour, la communauté portugaise représente le groupe migrant le plus important (16 % de la population totale). En 2011, près de 14% de la population totale était recensé comme étant âgé de plus de 65 ans, dont 3.7% de Portugais. Peu de recherches ont été menées concernant les projets futurs de ces immigrants portugais ainsi que des attentes mutuelles entre générations familiales. Dans notre étude nous nous concentrons sur (1) les projets futurs du retour migratoire des immigrants portugais âgés, (2) les caractéristiques des différents groupes (a)rester au Luxembourg, b) retourner au Portugal, c) alterner entre les deux pays) et (3) les stratégies d’autorégulation de chaque groupe en considérant le contrôle primaire et secondaire, la satisfaction de vie ainsi que le soutien intergénérationnel entre parents migrants âgés et leurs enfants adultes. L’étude présentée fait partie du projet IRMA (« Intergenerational Relations in the light of Migration and Ageing »), qui s’intéresse aux relations entre les enfants adultes et leurs parents âgés, en comparant des familles PT à des familles LU, toutes résidentes du Luxembourg. Seules les données concernant la génération des parents PT ont été utilisées pour la présente étude. Les participants, au nombre de N = 125 et âgés entre 41 et 80 ans (51.2% de femmes), ont été interrogés à l’aide d’un questionnaire standardisé (PT et FR). Tous les participants sont nés au Portugal, mais vivent au Luxembourg depuis en moyenne M = 31.36 ans (SD = 8.66). Les résultats démontrent la diversité au sein du groupe des immigrants. Les raisons d’un éventuel retour s’avèrent être de nature plutôt personnelle/individuelle, liées aux aspects du style de vie ainsi qu’à un sentiment d’identité culturelle étroitement associé au pays d’origine ; les motifs pour rester au Luxembourg ou alterner sont quant à eux plutôt sociaux/familiaux et pratiques. La venue de petits-enfants ainsi que le lieu de vie des enfants adultes semblent influencer la décision finale, laissant entrevoir l’importance des relations et du soutien intergénérationnels. La participation et le dévouement au pays d’accueil et le choix de rester peuvent aussi grandir au fur et à mesure des années passées dans ce pays. Les programmes pour la prévention de la santé et la promotion du bien-être devraient être plus étroitement adaptés aux besoins, souhaits et idéaux des immigrants âgés, tout en prenant en considération la question de savoir où ils veulent habiter dans le futur et pourquoi ainsi que le système de soutien intrafamiliale mis en place par les familles elles-mêmes. Les résultats seront davantage discutés et élaborés en vue d’éventuels futurs programmes de prévention et de soutien. [less ▲]

Recently, big data analytics has received important attention in a variety of application domains including business, finance, space science, healthcare, telecommunication and Internet of Things (IoT). Among these areas, IoT is considered as an important platform in bringing people, processes, data and things/objects together in order to enhance the quality of our everyday lives. However, the key challenges are how to effectively extract useful features from the massive amount of heterogeneous data generated by resource-constrained IoT devices in order to provide real-time information and feedback to the endusers, and how to utilize this data-aware intelligence in enhancing the performance of wireless IoT networks. Although there are parallel advances in cloud computing and edge computing for addressing some issues in data analytics, they have their own benefits and limitations. The convergence of these two computing paradigms, i.e., massive virtually shared pool of computing and storage resources from the cloud and real-time data processing by edge computing, could effectively enable live data analytics in wireless IoT networks. In this regard, we propose a novel framework for coordinated processing between edge and cloud computing/processing by integrating advantages from both the platforms. The proposed framework can exploit the network-wide knowledge and historical information available at the cloud center to guide edge computing units towards satisfying various performance requirements of heterogeneous wireless IoT networks. Starting with the main features, key enablers and the challenges of big data analytics, we provide various synergies and distinctions between cloud and edge processing. More importantly, we identify and describe the potential key enablers for the proposed edge-cloud collaborative framework, the associated key challenges and some interesting future research directions.

The human gastrointestinal tract is home for trillions of bacteria that influence homeostasis and health in a complex biological system: the gut microbiome. Accumulating evidence suggests that a state of pathological imbalance in the microbiome (dysbiosis) is present in patients suffering from colorectal cancer (CRC). To date, microbiome studies identified specific bacteria being associated with dysbiosis in CRC. Some of these bacteria (e.g. Fusobacteria) directly or indirectly interact with cancer and immune cells of their host. However, current studies only focused on certain microbes in detail, hence, their role in the etiology of the disease remains elusive. Accordingly, my project investigates the role of CRC-associated bacteria in tumor initiation and progression while addressing the question: which and what kind of microbes interact with, favor, or can cause CRC? In a first step, we identified CRC-associated bacteria, enriched at the tumor site of Luxembourgish CRC patients. By using Fusobacterium nucleatum as our study model, we predicted and optimized bacterial growth (media) in silico by using a genome-scale metabolic reconstruction model for a constraint-based modelling approach. Next, we assessed bacterial growth and metabolism in the optimized growth medium by using flow cytometry and mass spectrometry. Finally, we co-cultured the bacteria together with primary patient-derived cultures in the recently developed, microfluidics-based, human-microbial cross-talk model (HuMiX) [1]. As part of our ongoing validations, we infected patient-derived, healthy and cancerous 3D colonic organoids with our bacterial candidate. This workflow enables us to analyze pro-tumorigenic capacities of CRC-associated bacteria on healthy and cancerous colonocytes. It will serve as a promising tool for future analysis of host-microbial interaction mechanisms of various CRC-associated bacteria on a transcriptomic, proteomic, and metabolomic level.

The reasonable assessment of potential damage type of masonry structures in seismic-prone zone is very significant to strengthen existing masonry structures and guide the construction of the new building. The primary objective of the study is to propose and determine a reasonable assessment index to predict the damage type of masonry structures in different seismic intensity zones using the survey results of the 2008 Wenchuan earthquake and variance analyses comparison methods. Three potential theory assessment indexes are considered in the evaluation of damage of masonry structures, including wall density index , strength index , and combined index . In order to compare the feasibility of the three indexes, One-way analysis of variance and Scheffé’s method were used for in-depth discussion. Based on the proposed assessment indexes, further analyses and recommendations were provided. Results show the combined index has a high potential to predict the damage levels of masonry structures. Based on the study, several recommendations were provided for the masonry structures in seismic-prone zones. [less ▲]
