Full textThe originality of our contribution to the Romanian sociological and anthropological research concerns the analysis of the multidimensional relation between migration and the rural dwelling, emphasizing an understanding of the house as the meeting place of the different cultural models. Indeed, the house must be analyzed as a social product, with regard to the social and private life of the family which dwells there. Thus, our theoretical frame is based on the interplay between the sociological analysis of the migratory processes and their architectural and material expression. The central question of our research concerns the continuities and the discontinuities - observed with regard to the local tradition - which we find, after the fall of the communism regime, in the houses of the Romanian migrants, of rural origin. To answer this question, we chose an anthropological approach to the house, by conducting a qualitative field research (with villagers and migrants of Marginea village), in 2009, 2010 and 2011. We noticed that the new houses appear as hybrid forms, which articulate the local models to the new elements, brought by migration. So, we introduced two essential dimensions into the analysis of the concept of the migrant house: the "traces of the past" and the "traces of the migration". The first dimension refers to the influence of the old forms, models, practices, mentalities etc., while the second dimension indicates the new elements and innovations which penetrated the house design, its construction process and its exploitation
Originalitatea contributiei noastre noastre intre cercetarile sociologice si antropologice romanesti consta in analiza relatiei multidimensionale migratie-locuinta rurala, subliniind intelegerea locuintei migrantilor din tara de origine ca loc de intalnire a diferitelor modele culturale. Intr-adevar, casa trebuie vazuta ca un produs social si in relatie cu viata sociala si privata a familiei ce o locuieste. In consecinta, cadrul teoretic si de analiza imbina analiza sociologica a migratiei internationale cu expresia arhitecturala si materiala a acesteia. Intrebarea centrala a cercetarii priveste continuitatile si discontinuitatile - observate in raport cu modelele de dinainte de 1989 – ce se manifesta, dupa caderea regimului comunist, in proiectarea, realizarea si utilizarea locuintelor migrantilor din mediul rural. Pentru a raspunde la aceasta intrebare, am optat pentru o abordare antropologica a locuintelor migrantilor, realizand un studiu de caz in comuna Marginea, jud. Suceava. Anchetele de teren s-au desfasurat in intervalele iulie – octombrie 2009, iulie-octombrie 2010 si in august 2011. Am remarcat cum locuințele migrantilor se prezinta asemenea unor forme hibride ce combina elementele noi, aduse de migratie (« urmele migratiei »), cu referintele locale, de dinainte de 1989 (« urmele trecutului »). Am introdus astfel doua dimensiuni esentiale in analiza conceptului de locuinta a migrantului in tara de origine: « urmele trecutului » si « urmele migratiei ». Prima dimensiune se refera la influentele vechilor forme, modele, practici, mentalitati etc., in timp ce a doua dimensiune indica elementele noi si inovatiile ce au patruns in proiectarea, construirea si utilizarea acestor case

Full textThe evolution and maturation of Cloud Computing created an opportunity for the emergence of new Cloud applications. High-performance Computing, a complex problem solving class, arises as a new business consumer by taking advantage of the Cloud premises and leaving the expensive datacenter management and difficult grid development. Standing on an advanced maturing phase, today’s Cloud discarded many of its drawbacks, becoming more and more efficient and widespread. Performance enhancements, prices drops due to massification and customizable services on demand triggered an emphasized attention from other markets. HPC, regardless of being a very well established field, traditionally has a narrow frontier concerning its deployment and runs on dedicated datacenters or large grid computing. The problem with common placement is mainly the initial cost and the inability to fully use resources which not all research labs can afford. The main objective of this work was to investigate new technical solutions to allow the deployment of HPC applications on the Cloud, with particular emphasis on the private on-premise resources – the lower end of the chain which reduces costs. The work includes many experiments and analysis to identify obstacles and technology limitations. The feasibility of the objective was tested with new modeling, architecture and several applications migration. The final application integrates a simplified incorporation of both public and private Cloud resources, as well as HPC applications scheduling, deployment and management. It uses a well-defined user role strategy, based on federated authentication and a seamless procedure to daily usage with balanced low cost and performance.
O desenvolvimento e maturação da Computação em Nuvem abriu a janela de oportunidade para o surgimento de novas aplicações na Nuvem. A Computação de Alta Performance, uma classe dedicada à resolução de problemas complexos, surge como um novo consumidor no Mercado ao aproveitar as vantagens inerentes à Nuvem e deixando o dispendioso centro de computação tradicional e o difícil desenvolvimento em grelha. Situando-se num avançado estado de maturação, a Nuvem de hoje deixou para trás muitas das suas limitações, tornando-se cada vez mais eficiente e disseminada. Melhoramentos de performance, baixa de preços devido à massificação e serviços personalizados a pedido despoletaram uma atenção inusitada de outros mercados. A CAP, independentemente de ser uma área extremamente bem estabelecida, tradicionalmente tem uma fronteira estreita em relação à sua implementação. É executada em centros de computação dedicados ou computação em grelha de larga escala. O maior problema com o tipo de instalação habitual é o custo inicial e o não aproveitamento dos recursos a tempo inteiro, fator que nem todos os laboratórios de investigação conseguem suportar. O objetivo principal deste trabalho foi investigar novas soluções técnicas para permitir o lançamento de aplicações CAP na Nuvem, com particular ênfase nos recursos privados existentes, a parte peculiar e final da cadeia onde se pode reduzir custos. O trabalho inclui várias experiências e análises para identificar obstáculos e limitações tecnológicas. A viabilidade e praticabilidade do objetivo foi testada com inovação em modelos, arquitetura e migração de várias aplicações. A aplicação final integra uma agregação de recursos de Nuvens, públicas e privadas, assim como escalonamento, lançamento e gestão de aplicações CAP. É usada uma estratégia de perfil de utilizador baseada em autenticação federada, assim como procedimentos transparentes para a utilização diária com um equilibrado custo e performance.

Full textMobila affärssystem bildar ett av de mest attraktiva marknadssegment inom mobila informationstjänster. Den tredje generationens mobila kommunikationssytem (3G) kommer att bli ett viktigt steg fram mot konvergensen mellan telekommunikationsoch datakommunikationsindustrin. Särskilt konvergensen som äger rum mellan mobila teknologier och Internet erbjuder utmanande möjligheter för framtida applikationer och lösningar. De flesta nuvarande företag och tjänster inom mobilbranschen kan dock snarast betraktas som ett bidrag till denna konvergens. Många av de nuvarande idéerna och lösningarna är nämligen baserade på avgränsningar och problem som uppstår vid kombination av mobila system med Internet-baserade tjänster. I framtiden, när mobila nät har vuxit ihop med Internet till en symbios, kommer det inte längre att vara möjligt att förtjäna på detta slag av lösningar. En konkret lösning är det mobila middleware-konceptet, som bildar en logisk koppling mellan mobila teknologier och Internet-världen. Detta examensarbete studerar middleware-konceptet från en 3G-orienterad synvinkel och framför strategiska råd för företag som erbjuder detta slag av tjänster. En detaljerad diskussion om utvecklingen efter 3G presenteras. Arbetet lägger fram alternativa lösningar och strategiska implikationer deriveras. Implikationerna är motiverade bl.a. av en intervjuunders ökning som utfördes i samband med detta arbete. Temat trådlös datasynkronisering diskuteras som ett exempel för provisorisk middleware. Mobila filsystem införs som en intressant möjlighet för affärsapplikationer. Diverse möjligheter för fjärrkontroll av en arbetsplatsstation studeras och mätningar bevisar deras genomförbarhet för trådlösa applikationstjänster. Framträdande mobila Java-teknologier analyseras och presenteras som ett efficient underlag för plattformoberoende end-to-end-lösningaröver lag. En av de rekommenderade strategierna är baserad på det hybrida klientkonceptet, vilket presenteras som en realistisk lösning förövergången från nuvarande middleware-system till en (osäker) framtid av nativa, tjocka terminalapplikationer. Den strategiska horisonten för detta är två år. Utgående från detta koncept utvecklades en prototyp som exempel för en sådan applikation. Arbetet definerar och diskuterar dessutom diverse strategiska scenarier. Slutligen nämns problematiken om operatörernas framtida differentieringsmöjligheter och rollen av affärssystem i en fullständigt IP-baserad värld. 3G nät och terminaler kommer att skapa ett stort antal nya användningar och affärsmöjligheter, men ändringen kommer också att medföra nya utmaningar och risker. Detta illustreras med hjälp av företaget Smartner som exempel för en leverant ör av mobila middleware-lösningar för affärsanvändningar. Som demonstrerat i detta fall, anses i jämförelse med nuvarande applikationslösningar en signifikant teknologisk reorientering vara nödvändig, för att bevara ett långvarigt perspektiv.
Langattomat yrityssovellukset ovat nykyään yksi kiinnostavimmista mobiilimarkkinoiden segmenteistä. Kolmannen sukupolven (3G) mobiilit viestintäjärjestelmät tulevat olemaan merkittävä askel kohti telekommunikaatioja dataliikennealojen yhdistymist ä (ns. konvergenssia). Itse asiassa mobiiliteknologian ja Internetin lähentyminen mahdollistaa entistä hyödyllisempien mobiilisovellusten ja -ratkaisuiden rakentamisen tulevaisuudessa. Tällä hetkellä useat mobiiliyritykset ja mobiilisovellusten tuottajat ovat kuitenkin osana tätä yhdistymisprosessia. Monet nykyiset ideat ja ratkaisut ottavat nimittäin lähtökohdakseen rajoitukset, joita nykyiset tietoliikenneverkot asettavat yhdistyessään Internet-pohjaisiin palveluihin. Tulevaisuudessa, kun mobiiliverkot ja Internet ovat yhdistyneet, ei ole enää mahdollista ansaita rahaa tällaisten perinteisten ratkaisuiden avulla. Yksi konkreettinen ratkaisumalli perustuu mobile middleware -käsitteeseen, joka liittää yhteen mobiiliteknologian ja Internetin. Tässä diplomityössä tutkitaan middleware- käsitettä yrityssovellusten tarjoamisessa erityisesti 3G-verkoissa, ja työssä esitellään strategisia suosituksia näiden sovelluspalveluiden tarjoajille. Työssä käyd ään perusteellisesti läpi kolmannen sukupolven jälkeistä kehitystä. Vaihtoehtoisia ratkaisuja esitellään, ja joitakin strategisia vaikutuksia tuodaan myös esille. Vaikutuksia perustellaan tuloksilla, joita tämän projektin osana tehty kysely paljasti. Tiedon langatonta synkronisointia tarkastellaan esimerkkinä tilapäisestä middlewaresta. Mobiileihin tiedostojärjestelmiin liittyvät asiat nähdään mielenkiintoisena mahdollisuutena yrityssovelluksille. Toimistojärjestelmien etäkäyttömahdollisuuksia on tutkittu ja niiden sopivuutta langattomaan sovellustarjontaan on mitattu. Kehittyviä mobiileja Java-teknologioita pidetään tehokkaana alustana, jonka avulla voidaan tarjota kaikkialla saatavilla olevia, päätelaiteriippumattomia ratkaisuja loppuasiakkaille. Yhtenä suositelluista strategioista tämä diplomityö esittelee yksinkertaisen päätelaitesovellusmallin, jonka avulla nykyisistä middleware-ratkaisuista voidaan siirtyä tulevaisuuden kehittyneempiin päätelaiteratkaisuihin kahden vuoden sisällä. Tähän konseptiin perustuen työssä on kehitetty esimerkki 3G-älypuhelimen sovelluksesta. Lisäksi esitellään ja arvioidaan mahdollisia strategisia skenaariovaihtoehtoja. Tämä diplomityö käsittelee myös operaattoreiden differointimahdollisuuksia ja yrityssovelluksia täysin IP-pohjaisissa verkoissa. 3G-verkot ja -päätelaitteet tuovat mukanaan laajan valikoiman uusia sovelluksia ja liiketoimintamahdollisuuksia, mutta tämä muutos merkitsee myös uusia haasteita ja riskejä. Tätä haastetta kuvataan tutkimuksen esimerkkiyrityksen Smartnerin tapauksessa, joka on yrityssovelluksiin fokusoitunut mobiilien middleware-ratkaisuiden tarjoaja. Tutkimus tuo esille, miten Smartnerin nykyiset sovellukset huomioon ottaen tarvitaan valtava teknologinen suunnanmuutos pitkäaikaisen perspektiivin säilyttämiseksi.

Full textBackground: The clinical prognosis of glioblastoma, the most aggressive primary brain tumor in adults, remains poor (Stupp et al. 2005). Nanomedicine could provide new therapeutic tools to overcome current limitations. Au@DTTPA(Gd) gold-gadolinium hybrid nanoparticles are being studied for their radiosensitizing potential in vitro and in vivo (Alric et al. 2008 and Miladi et al. 2014). The main objective of this thesis work is to evaluate in vitro and in vivo the anti-invasive potential of Au@DTDTPA(Gd) associated with radiotherapy.Results: From 2D and 3D in vitro cell cultures, ex vivo organotypic cultures and in vivo cranial window model on the infiltrating line U251 and the radioresistant line U87, we evaluated the anti-invasive potential of Au@DTDTPA(Gd) nanoparticles with or without radiotherapy. Nanoparticles alone reduce the invasive capacity of U251 spheroids but are not related to MMP2 proteolytic activity and MMP14 expression. They also reduce the abilities of U251 cells to migrate both collectively and individually. At the same time, nanoparticles affect the biomechanical capacities of U251 cells, which are marked by an increase in the number and diameter of actin fibers at the level of cell protrusions, an enhanced membrane rigidity. These changes are associated with an increase in cell traction forces, expression of adhesion proteins and a decrease in the number of protrusions. All these data would explain the inhibition of cell motility of U251 cells by Au@DTTPA(Gd) nanoparticles. We then highlighted the effects of Au@DTDTPA(Gd) associated with different radiotherapy protocols on the radioresistant U87 cell line. The in vitro 3D, ex vivo and in vivo follow-ups indicate a decrease in the progression of U87 cells. We have developed a 3D in vitro model that allows the recovery of migratory cells from treated spheroids. After treatment, we observed that Au@DTDPA(Gd) alone or in combination with radiotherapy decreased the number of migratory cells, as well as their viability by induction of mitotic catastrophes. The combined treatment also decreased both the secretion and activity of MMP2 in migrating cells. Fluorescence microscopy observations reveal a loss of intercellular junctions and compromised expression of Cx43 in intercellular junctions. Culture of migratory cells in a neurosphere medium allowing stem cell selection showed that treated migratory cells form fewer neurospheres and have a reduced diameter. These results suggest that migratory cells would lose their stem-like characteristics.Conclusion: Our overall results suggest that Au@DTTPA(Gd) nanoparticles possess anti-invasive effects by disrupting the biomechanical capabilities of GBM cells. Moreover, Au@DTDTPA(Gd) combined with radiotherapy reduce the invasive properties of migrating GBM cells by inducing mitotic catastrophes, loss of intercellular junctions and attenuation of their stemness. These results show that Au@DTDTPA(Gd) and radiotherapy have therapeutic potential for future preclinical studies

Full textThe main goal of this PhD work is to study photo-induced matter deformation phenomena in thin polymeric film containing azobenzene moieties. This study is based on the in-situ observation of surface relief gratings kinetic of formation under illumination by an interference pattern. The observation relies on a coupled microscopy technique, allowing to correlate photo-induced morphology with the electromagnetic field distribution, with a resolution better than the lattice pitch. The study as a function of the light polarisation and of the film thickness shows that four microscopic mechanisms are involved in the photo-induced deformation of the azo-polymer: the optical reorientation of chromophore, the local reorganization of the matrix, oriented matter transport and the photobleaching. The contribution of these different mechanisms is evidenced by two phenomena observed for the first time. First, the kinetic of deformation presents a transition between two regimes, one, at short time, in phase with the light excitation, the other, at longer time, in opposition of phase. Second, the morphology of the induced relief grating depends strongly on the film thickness. This PhD work shed light on previous and somehow contradictory results, in particular in term of response of azo-polymer films at an excitation in near filed and far field optics

The migration mechanism can provide services, computing jobs and resources moved from a virtual environment to another virtual environment and can be categorized into resource migration, host migration and network migration. The network migration mechanism can move all virtual machines within the subnet, including services, storage space and other resources to another subnet, while retaining the network topology and network infrastructure. To achieve the objective of network migration, in the paper, we proposed a migration mechanism that can move all virtual machines and the network environment to another set of machines on a hybrid cloud environment. The proposed solution is implemented based on Open Flow and XEN, and use of existing network protocols. The emulation results show that the proposed solution can provide very good performance.

Before the cloud concept being proposed, organizations built their own private cloud environment to support their own computing resources consumption. But it is not efficient since most of the time the computing resources are idled. Cloud computing provides a new charging concept, pay as you go. The computing resource is on-demand. Public cloud providers build their own computing farm and rent the resources to the costumers. But there are some disadvantage moving all the organization’s computing resource to the cloud. Hence the hybrid cloud is being proposed. The hybrid cloud model allows organizations to build their own private cloud for their basic usage, while using the public clouds’ resource when needed. By connecting the public cloud and private cloud together, organizations can dynamically manage the computing resource, so that the organization can run jobs at a minimum cost while guarantee certain efficiency. But the problem of how to dynamically set up the environment is still remains. We proposed an agent-based intelligent software migration framework. With the framework, agents will automatically monitor the execution environment both in private cloud and public cloud. The agents will dynamically set up or shut down computing resources according to all the jobs’ status. After resizing the computing resources, the agents will migrate some jobs to public cloud to increase the total system’s efficiency. We also proposed three kinds of policy that can be used on hybrid cloud environment. The policy will decide when the computing resource needs to be resized, and which job will be migrated to the public cloud.

Live migration is an important function in the virtual machine. Pre-copy and Post-copy are two technologies of Live migration. Pre-copy Live migration technology has the characteristics of the low downtime, but to running a write-intensive program will result in high total migration time. Post-copy live migration technology has the characteristics of the low total migration time, but has higher downtime. Trying to have a better balance between downtime and total migration time, this paper presents a Hybrid copy architecture, combined with the Pre-copy and Post-copy. Hybrid copy architecture uses the two Pre-copy iterations to reduce the number of pages needs to send in pull phase, and then determine whether to effectively reduce the dirty page number. If effectively, then enter the Pre-copy branch. If not effectively, then enter the Pre-copy branch. Hybrid copy architecture to running write-intensive programs and Comprehensive type programs, the downtime can be reduced by 14% to 50%, the total migration time can be reduced by 22% to 33%. Hybrid copy architecture can present a balance Pre-copy live migration and Post-copy live migration.

When applications need a large amount of I/O, SSDs can provide a better performance than HDDs. As a result, data with frequent accesses could be allocated to SSDs in order to improve performance. However, the SSDs’ price is more expensive than HDDs, so we have to make proper data migration between HDDs and SSDs. In the thesis, we will propose a priority-based object migration design for NoSQL databases in a hybrid storage system. The method can place high-priority data in SSDs with fast access property and allocate low-priority data to HDDs with low cost to improve the performance of NoSQL databases. The experimental results also show that the proposed method can achieve the goal.

Migration is an important research issue in cloud computing. For example, when the some emergency situations, the computers for the cloud computing servers should be closed, we need to move the cloud computing resources from a virtual environment to another virtual environment. The network migration can be used to move the entire cloud computing resources and network configuration from a computer center to another computer center. In our paper, we proposed the live network migration solution based on the mobile IPv6 NEMO. The proposed solution uses tunnel technology to establish logical communication between the migrated computer center and the target computer center, and uses the binding updated to change the network topology. The experiment results show that the proposed solution can provide live network migration for the hybrid cloud network environment.

Human adipose-derived stem cells (hADSCs) are one of the promising cell sources in regenerative medicine because they can be obtained in abundant quantity and harvested by minimally invasive procedure such as liposuction. Unlike embryonic stem cells (hESCs) and human induced pluripotent stem cells (iPSCs), adult stem cells do not generate the ethical concerns that accompany hESCs and are cultivated in relatively low cost. Furthermore, the xeno-free culture of hESCs and hiPSCs is difficult to achieve and/or are extremely costly. Therefore, hADSCs are considered to be a more attractive source of stem cells than hESCs and hiPSCs. However, hADSCs are limited for application because of their low pluripotency and differentiation ability compared with hESCs and hiPSCs. It is a critical issue how to maintain or increase the pluripotency of hADSCs. The adipose tissue was treated with collagenase to digest, followed by centrifugation in this study. Subsequently, stromal vascular fraction (SVF) was obtained. Cells in SVF were not only heterogeneous and contain many different types of cells leading to various genotypes but also held high pluripotency. Although hADSCs could be purified by culturing on tissue culture dishes, the pluripotency significantly decreased with time. In order to improve the clinical application of hADSCs, the hybrid membrane method that takes shorter time to purify hADSCs (i.e. less than 30 min) than conventional culture method (i.e. 5-12 days) has developed in this study where hADSCs are purified from SVF cell solution with extremely high purity and pluripotency. A SVF cell solution was permeated through the porous membranes with a pore size from 8 m to 25 m, and membranes were incubated in cell culture medium for 15-18 days. The hADSCs migrated from 10% PLGA/silk screens hybrid membranes contain an extremely high percentage (e.g. >95%) of cells positive for mesenchymal stem cell markers and express higher pluripotent genes (Oct4, Sox2, Klf4 and Nanog) than the cells after culturing by conventional culture method. It is noteworthy that the pluripotency of cells in SVF could be kept or even enhanced in permeate and recovery solution filtered by 10% PLGA/silk screen hybrid membranes. Besides, the alkaline phosphatase activity (ALP) was analyzed after 14 days. Alizarin red staining, von Kossa staining were observed after 28 days. It was indicated that cells in permeate and recovery solution purified by10% PLGA/silk screen hybrid membranes had higher ability to differentiate into osteoblasts compared with primary cells and cells after culturing by conventional culture method.

The dissertation proposed a numerical model of hybrid finite-element and particle-in-cell method to simulate charged ion migration in the cross-channel capillary zone electrophoresis system. Analytes separated by capillary zone electrophoresis are governed by the ion migration with different charge-to-mass ratios. Different to the traditional numerical method, this method can be used to simulate the migration phenomenon of the differently charged ions for handling complex geometries and irregular boundary conditions in the capillary zone electrophoresis system. This research focused on the effects of Debye length and corner arc radius on the migration phenomena of the positive and negative ions in the injection and separation process. The numerical results indicate that these effects can affect obviously the migration phenomena of differently charged analytes as expressed in the following. The positive and negative ions are subject to opposite electric field force relative to the buffer solvent. Hence, the positive ions migrate into the separation channel faster than the negative ions. With decreasing the Debye length, the positive and negative ions are faster carried into the separation channel. Furthermore, more positive ions migrate into the separation channel and migrate more far away from the injection channel. Meanwhile, the negative ions migrate more close to the upper wall of the separation channel. The results indicate that the short Debye length can shorten time for the injection process and provide more analytes for the separation process. In the injection process, the positive and negative ions migrate not only faster into the separation channel but also more far away from the injection channel with increasing the corner arc radius. In the separation process, the zones of positive and negative ions are wider and the time to completely separate is longer with increasing the corner arc radius. Consequently, as corner arc radius is larger, more time is needed to inject and separate charged ions. The numerical results provide useful insights into the influences of the electric field on the migration of differently charged ions in capillary zone electrophoresis systems. These findings have significant implications for design and control of capillary zone electrophoresis systems.

In recent years, emerging non-volatile memory (NVM) has favorable properties, such as low leakage and high density and has attracted a lot of attention. Among them, spin-transfer torque magnetoresistive random access memory (STT-MRAM) that has read speed comparable to SRAM is a good candidate to build large last-level caches (LLCs). However, STT-MRAM suffers from long write latency and high write energy. To mitigate the impact of asymmetric read/write energy and latency, hybrid cache designs have been proposed to combine the merits of STT-MRAM and SRAM and good block placement and migration policies are necessary to use the hybrid cache efficiently. In this thesis, we find that conflict miss occurs on L2 frequently causing the blocks thrash between L2 and LLC. If the thrashing block that cause write activities, i.e. dirty thrashing block, are placed in STT-MRAM of hybrid LLC, these will result in excessive energy consumption, especially in memory bound benchmarks. Therefore, this thesis proposes repetitive access aware placement and migration (RAP) to mitigate energy consumption caused by thrashing block. RAP places dirty thrashing blocks into SRAM and migrate clean thrashing blocks, which is evicted from SRAM, to STT-MRAM. RAP can reduce up to 38.04% and 19.96% reduction on average of LLC energy for running four copies of workloads on a four-core system. For a four-core system that runs mix workloads, our technique also can reduce up to 36.60% and 25.92% on average of LLC energy. When compared to the previous access aware policy and adaptive placement and migration policy, the proposed technique can reduce 20.20% on average (up to 35.68%) and 9.75.% on average (up to 26.67%) energy consumption with insignificant performance degradation. Evaluation results show large energy consumption reduction with minimal performance loss.

Human adipose-derived stem cells, hADSCs, can be obtained by isolation from fat tissue, which is currently a more practical source of stem cells than human induced pluripotent stem cells (hiPSCs) and embryonic stem cells (hESCs). Currently, several clinical trials use hADSCs, whereas only a few clinical trials have been performed using hiPSCs and hESCs. However, hADSCs are known to show heterogeneous characteristics and contain different pluripotency and differentiation abilities. Therefore, it is expected that the stem cell characteristics, pluripotency, and differentiation abilities should be different for hADSCs isolated by different isolation methods. hADSCs are typically isolated by cell culture of stromal vascular fraction (SVF, primary hADSC solution) where the SVF solution can be obtained by collagenase digestion of fat tissues followed by centrifugation. The isolated hADSCs can possess different purity levels and divergent properties depending on the purification methods used. It is innovated that the membrane migration method through Nylon mesh filter purifies hADSCs from a fat tissue solution with extremely high purity and pluripotency in my laboratory. A primary fat-tissue solution was permeated through the porous membranes (e.g., Nylon mesh) with a pore size from 8 to 25 μm, and the membranes were incubated in cell culture medium for 15-18 days. In this study, I developrd a new membrane migration method using Nylon mesh membranes having optimal pore sizes, 11 and 20 μm, and PLGA/silk membranes where optimal extracellular matrix (ECM) was coated on the membranes, which could purify hADSCs. The isolated hADSCs are expected to have high pluripotency and high differentiation ability into chondrocytes, osteoblasts and adipocytes. hADSCs were isolated from adipose tissue by the membrane migration method where different membranes were used, e.g., (a) Nylon mesh and PLGA (poly (lactic-co-glycolic acid))/silk screen membrane, (b) Nylon mesh and PLGA/silk screen membrane coated with collagen type I, (c) Nylon mesh and PLGA/silk screen membrane coated with human recombinant-vitronectin, (d) Nylon mesh and PLGA/silk screen membrane coated with human fibronectin. Collagen type I is xeno-containing materials, whereas another extracellular matrices (ECMs) were xeno-free materials. The hADSCs that migrated from the membranes kept an extremely high percentage (e.g., >98%) expression of mesenchymal stem cell markers (CD44, CD73, and CD90) and showed almost one order of magnitude higher expression of some pluripotency genes (Oct4, Sox2, and Nanog) compared with cells isolated using the conventional culture method.
