Proportional and Preemption-Enabled Traffic Offloading for IP Flow Mobility: Algorithms and Performance Evaluation
2018
IP Flow Mobility (IFOM) enables a user equipment to offload data traffic at the IP flow level. Although the procedure of IFOM-based flow offloading has been specified by 3GPP, how many IP flows should be offloaded and when offloading should be performed are not defined. Consequently, IP flows may be routed to a target access network which has a strong signal strength but with backhaul congestion or insufficient access capability. In this paper, we propose two algorithms, referred to as proportional offloading (PO), and proportional and preemption-enabled offloading (PPO), respectively, for IP flow offloading in hybrid cellular and wireless local area networks. The PO algorithm decides an op…
Proxy Mobile IPv6-Based Seamless Handover
2013
A prospective next generation wireless network is expected to integrate harmoniously into an IP-based core network. It is widely anticipated that IP-layer handover is a feasible solution to global mobility. However, the performance of IP-layer handover based on basic Mobile IP (MIP) cannot support real time services very well due to long handover delay. The Internet Engineering Task Force (IETF) Network-based Localized Mobility Management (NETLMM) working group developed a network-based localized mobility management protocol called Proxy Mobile IPv6 (PMIPv6) to reduce the handoff latency of MIPv6. Moreover, PMIPv6 provides the IP with the mobility to support User Equipments (UEs) without it…
Cultural and Landscapes Heritages: Mobility, Fruition and Accessibility for all
2021
At such a delicate historical moment, in which the pandemic health emergency has reduced the mobility of citizens, a new resilient culture is affirming its capacity to encourage and guarantee the use of cultural and landscape assets for all. This study analyzes some international and national experiences that have already been implemented, or are at an advanced planning stage, which point to a new way of understanding the accessibility of places by users with specific needs and permits their visitation which was previously impossible. Our discussion will deal with Agrigento in particular: the city itself, the Valley of the Temples, its historical center and all the naturalistic treasures of…
Investigation of the Electrophoretic Mobility of the Actinides Th, U, Np, Pu, and Am in Different Oxidation States.
2019
The electrophoretic mobilities (μe) of the actinides Th and U-Am in different oxidation states (prepared in 1 M HCl and 1 M HClO4) have been determined by capillary electrophoresis (CE)-inductively coupled plasma mass spectrometry (ICPMS) using 1 M acetic acid as the background electrolyte, which has proven to provide an excellent setup for trace analysis at environmentally relevant concentrations (1 × 10-9 M). The values are independent of the respective acid solution. The μe of the Pu oxidation states +III to +VI have been measured. They agree with both the available literature data and the redox-stable analogues (Eu(III), Th(IV), Np(V), U(VI)) that have also been investigated. The trend …
Note in tema di acquisto di immobili da costruire dopo l'emanazione del Codice della crisi d'impresa
2019
Il nuovo Codice della crisi d’impresa e dell’insolvenza, emanato con d.lgs. 12 gennaio 2019, n. 14, in attuazione della legge delega 19 ottobre 2017, n. 155, contiene alcune previsioni in tema di acquisti di immobili da costruire che si collocano nel solco delle regole di protezione del contraente debole. L'Autore esamina le novità introdotte dal legislatore alla luce del precedente dibattito giurisprudenziale e dottrinale, al fine di segnalare i progressi e le lacune della normativa in punto di tutela degli acquirenti di immobili da costruire.
Enhancement of antibiotic productions by plasma modified PLA electrospun membranes in Streptomyces coelicolor immobilized-cell cultivations
2017
This study, encouraging the use of PLA membranes for actinomycetes cultivations, could unveil functional insights associated with antibiotic production and S. coelicolor cellimmobilization
Rapports au travail et socialisations singulières d'étudiant·es issu·es de milieux populaires.
2019
International audience; L'analyse de 19 entretiens auprès d'étudiant·es issus de milieux populaires met en avant un rapport au travail pluriel, qui s'articule autour de la dimension expressive et instrumentale de l'activité professionnelle espérée. La place de la dimension expressive tient beaucoup au statut d'étudiant du supérieur et distingue les jeunes rencontrés d'autres jeunes issus de milieux populaires. Néanmoins, la promotion sociale espérée et les attentes à son égard dépendent de la socialisation en cours d'études et de l'évolution des conditions socio-économiques des étudiant·es rencontré·es. Cette réversibilité révèle la fragilité de la mobilité sociale en train de se faire.
A computational model of postprandial adipose tissue lipid metabolism derived using human arteriovenous stable isotope tracer data
2019
Given the association of disturbances in non-esterified fatty acid (NEFA) metabolism with the development of Type 2 Diabetes and Non-Alcoholic Fatty Liver Disease, computational models of glucose-insulin dynamics have been extended to account for the interplay with NEFA. In this study, we use arteriovenous measurement across the subcutaneous adipose tissue during a mixed meal challenge test to evaluate the performance and underlying assumptions of three existing models of adipose tissue metabolism and construct a new, refined model of adipose tissue metabolism. Our model introduces new terms, explicitly accounting for the conversion of glucose to glyceraldehye-3-phosphate, the postprandial …
Trap-limited mobility in space-charge limited current in organic layers
2009
Space-charge limited current transport in organic devices, relevant to the operation of a range of organic optoelectronic devices, is analyzed in the frequency domain. The classical multiple trapping picture with one transport state and one trap level is used as the basis for the descriptions. By varying the energetic and kinetic properties of the traps, we show that the admittance and the capacitance spectra are considerably modified depending on the interplay between the trap-limited mobility and the trap kinetics. We point out that capacitance steps at low-frequency, usually found in experiments, are observed only for slow traps. © 2008 Elsevier B.V. All rights reserved.
Sequential analysis of CD34+ and CD34− cell subsets in peripheral blood and leukapheresis products from breast cancer patients mobilized with SCF plu…
2001
Administration of stem cell factor (SCF) has been proven to enhance cytokine-induced mobilization of CD34+ hematopoietic progenitor cells (HPC) into the peripheral blood (PB). The aim of the present study was to explore in a homogeneous group of 22 uniformly treated breast cancer patients: (1) the kinetics of mobilization into PB of both CD34+ and CD34- cell subsets, including dendritic cells, in sequential samples obtained from day +7 up to day +12 after mobilization; and (2) the composition of the CD34+ and CD34- cell subsets present in the two leukapheresis products obtained for each patient. The following CD34+ and CD34- subsets were analyzed: early CD34+ HPC, erythroid-, myeloid- and B…
