Abstract:
To construct a hierarchical lattice structure (HLS), truss wall is introduced into ordinary lattice structure (OLS). Young’s modulus, yield strength and buckling stress of HLSs were evaluated theoretically. Failure maps of different HLSs were plotted and compared based on the theoretical analyses. It is indicated that mechanical behaviors of hexagonal HLSs made of triangular lattice walls can be greatly enhanced by the hierarchical wall structure, while properties of triangular HLSs are weakened, except the anti-buckling resistance. When HLSs are made of bending-dominated honeycomb walls, their properties will be reduced, indicating that hierarchical structure should be appropriately designed to make ultra-light structures benefit from this construction. This viewpoint is strengthened by the discussions on the performances of high order lattice structures, where only bending-dominated HLSs with stretching-dominated lattice wall benefit from the hierarchy.

Abstract:
Culture media are frequently used in the evaluation of metabolical functions of hepatocytes in hybrid liver support systems (hLSS). However, media compositions differ substantially from those of plasma. Therefore, our study was designed to investigate whether current in vitro studies with medium are suitable to assess the metabolical competence of hLSS-cultures during clinical application as well as to explore whether the cell nutrition with medium provides a suitable modus operandi for stand by cultivation. Paired bioreactor cultures were perfused with either Williams’ Medium E (MPB) or human plasma (PPB). About 6x108 primary pig hepatocytes (>97% viability) were cultured in three laboratory scale bioreactors designed according to Gerlach's bioreactor-concept. Different perfusion protocols were initiated after a standardised period allowing for cell attachment and reorganisation in aggregates. Whereas patterns of enzyme release were similar in both protocols the metabolical behaviour was different between MPB (anabolic state) and PPB (catabolic state). Furthermore, compared to MPB the lidocaine-MEGX-tests for PPB demonstrated lower MEGX-concentrations and a different reaction pattern. We conclude that the nutrition of hepatocytes with medium during the stand by period itself might influence the cell function and subsequently the efficacy of the hLSS-treatment during clinical application.

Abstract:
The present study aims to further the research on heritage language speakers (HLSs) by providing the socio-linguistic profiles and identities of an uninvestigated community of heritage speakers, namely the Greeks of Chicago, thus offering data for a less-studied HL, Greek. The participants were fifty-four (N=54) first, second, and third-generation Greek HLSs. The socio-linguistic data were collected through an online survey, while identification with Greek culture as well as ethnic attachment and practice of Greek traditions were investigated through the content analysis of data from the Greek Heritage Language Corpus. The results of the study are discussed with respect to how they can improve our knowledge of the educational needs of Greek HL learners. This research-based knowledge can be employed for addressing the academic needs of HL learners through educational programs. The authors propose an agenda for a more linguistically and culturally responsive education program for HL learners, in general, and Greek HL learners in diasporic communities, in particular.

Abstract:
ABSTRACT We present measurements of the linear galaxy bias of Hα and [O iii] emission-line galaxies (ELGs) for the High Latitude Spectroscopic Survey (HLSS) of Nancy Grace Roman Space Telescope (or Roman), using galaxy mocks constructed using semi-analytical model for galaxy formation, Galacticus, with a large cosmic volume and redshift coverage. We compute the two-point statistics of galaxies in configuration space and measure linear bias within scales of 10–50 h−1 Mpc. We adopt different selection algorithms to investigate the impact of the Roman line flux cut, as well as the effect of dust model used to calibrate Galacticus, on the bias measurements. We consider galaxies with Hα and [O iii] emissions over the redshift range 1 < z < 3, as specified by the current baseline for the Roman HLSS. We find that the linear bias for the Hα and [O iii] ELGs can be expressed as a linear function with respect to redshift: b ≃ 0.9z + 0.5 for H$\alpha \, (1\lt z\lt 2)$, and b ≃ z + 0.5 for [O iii] (2 < z < 3). We have also measured the halo occupation distributions of these Hα and [O iii] ELGs to understand their distribution within dark matter haloes. Our results provide key input to enable the reliable forecast of dark energy and cosmology constraints from Roman.

Abstract:
Hemopoietic lineage switch (Hls) 5 and 7 were originally isolated as genes up-regulated during an erythroid-to-myeloid lineage switch. We have shown previously that Hls7/Mlf1 imposes a monoblastoid phenotype on erythroleukemic cells. Here we show that Hls5 impedes erythroid maturation by restricting proliferation and inhibiting hemoglobin synthesis; however, Hls5 does not influence the morphology of erythroid cells. Under the influence of GATA-1, Hls5 relocates from cytoplasmic granules to the nucleus where it associates with both FOG-1 and GATA-1. In the nucleus, Hls5 is able to suppress GATA-1–mediated transactivation and reduce GATA-1 binding to DNA. We conclude that Hls5 and Hls7/Mlf1 act cooperatively to induce biochemical and phenotypic changes associated with erythroid/myeloid lineage switching.

Abstract:
Cell therapy may be regarded as a feasible alternative to whole organ transplantation to treat end-stage liver diseases. Human liver stem cells (HLSCs) are a population of cells easily obtainable and expandable from a human adult liver biopsy. HLSCs share with mesenchymal stromal cells the same phenotype, gene expression profile, and differentiation capabilities. In addition, HLSCs show a specific commitment to the hepatic phenotype. Injection of HLSCs into immunodeficient mice fed with a methionine-choline-deficient diet to induce nonalcoholic steatohepatitis ameliorates liver function and morphology. In particular, HLSC treatment induced a reduction of liver fibrosis and inflammation at morphological and molecular levels. Moreover, HLSCs were able to persist for up to 3 weeks after the injection. In conclusion, HLSCs have healing effects in a model of chronic liver disease.

Abstract:
We propose that nanogels (HLGs) prepared by simply blending an epidermal growth factor (EGF)-loaded hyaluronan (HA)-based nanoformulation and poloxamers can be efficient transdermal drug carriers. In particular, due to the thermogelling behavior of poloxamer, when the HLGs, which are liquid at room temperature, are applied to the skin's surface, they form a gel at skin temperature. First, lipid-based nanoformulations (EGF-LNs) were fabricated by the lipid thin film method and then chemically conjugated with HA on the surface of the films to prepare EGF-loaded HA-based nanoformulations (EGF-HLNs). Both EGF-LNs and EGF-HLNs exhibited a uniform size and spherical lamellar structure. The EGF-HLN was added to a poloxamer solution to form EGF-HLG, which is a liquid at room temperature and a gel at skin temperature. HLGs have been shown to be able to deliver and permeate EGF well into the skin using both in vitro and in vivo systems, thus serving as an effective transdermal delivery system. In addition, it has been confirmed that this system could be a possible implantable drug carrier. Therefore, HLGs, which are uncomplicated and easily prepared, are expected to be easily used not only in the pharmaceutical field but also in the cosmetic field.

Abstract:
Hybrid liver support devices (HLSDs) developed for the treatment of fulminant hepatic failure often perform well on a laboratory scale but rapidly lose their metabolic functions, or are not therapeutically effective, on a clinical scale. This suggests that the procedures adopted so far for the design of HLSDs are susceptible to improvement. In this paper, we discuss how essential a reliable and thorough kinetic characterization of the liver cell metabolic reactions is to the design of a clinically effective membrane HLSD. The features of the bioreactors used for the kinetic characterization of liver cell reactions are presented and discussed on the basis of the multifactorial nature of such reactions. The relevance of kinetics to the design of a membrane HLSD is also discussed with respect to the effect of the kinetics of oxygen consumption on the performance of the device.

Abstract:
Tumor is basically a most common disease of brain and the Brain Tumor (BT) treatment has crucial significance. A diagnostic procedure called MRI image that is employed for detecting BT. It is the utmost important and intricate tasks in numerous medical-image applications since it typically involves a huge quantity of data. A lot of methods were applied in BT detection ranging as of image processing to examine the BT; however, the prevailing BT technique is tedious and less effective. So, this paper proposed the detection of the BT in MRI images utilizing optimized ANFIS classifier. Originally, the input MR image is preprocessed utilizing Gaussian Filter (GF) that removes the noise from the inputted image, additionally, the non-brain tissues (NBT) are removed using the technique of skull stripping (SS). After that, segmentation is performed wherein the tumor part is segmented utilizing CBAC technique and edema part is segmented utilizing HLSS segmentation technique. Then, GLCM in addition to GLRLM features are extracted afterward that extorted features is chosen by BFO algorithm. Finally, the selected features inputted to the optimized ANFIS classifier that classifies the tumor class types as Meningioma, Glioma, along with Pituitary. In ANFIS, the optimization procedure is achieved utilizing the PSO. The proposed system’s performance is contrasted to the prevailing systems regarding precision, recall, specificity, sensitivity, accuracy, together with F-Measure.

Abstract:
Abstract The J2E erythroblastoid cell line responds to erythropoietin (Epo) by morphological maturation and hemoglobin synthesis. However, on rare occasions, these cells have undergone a spontaneous lineage switch and display features of monoblastoid cells which do not respond to Epo. Amongst the genes up-regulated in the monoblastoid variants were Hemopoietic lineage switch (Hls) 5 and 7. Hls5 is a recently identified member of the RING finger, B Box, Coiled coil (RBCC) or tripartite motif (TRIM) family, which includes PML, a gene involved in acute promyelocytic leukaemia. Hls7 is the murine orthologue of Myeloid leukaemia factor 1 (Mlf1), a gene involved in a t(3;5), associated with acute myeloid leukaemia. We have shown previously that Hls7/Mlf1 imposes a dramatic phenotypic change upon the erythroid cells, rendering them monoblastoid (Williams, J. et al EMBO 1999). We have studied the role of Hls5 and Mlf1 in erythroid commitment and differentiation. Ectopic expression of Hls5 inhibits globin production in erythroid cells and suppresses development of B-FUE and C-FUE. A yeast-two-hybrid screen identified FOG-1 as a binding partner of Hls5. Significantly, FOG-1 is a transcriptional co-regulator of GATA-1, which controls globin gene expression. While Hls5 is able to enhance the repression of GATA-1 activity imposed by FOG-1, it is also able to repress GATA-1 transcriptional activity in the absence of FOG-1. Using electrophoretic mobility shift assay we have shown that Hls5 is able to reduce GATA-1 binding to DNA in a dose dependant manner. This observation that Hls5 reduces GATA-1 binding to promoter elements is mirrored by chromatin immunoprecipitation assays. Expression of MLF1 is highest in CD34+ cells, but is markedly down regulated during erythroid differentiation. Microarray analysis identified a number of known transcriptional regulators differentially expressed in the presence of Mlf1 including ets1, Myc intron binding protein and Tbr2. Mlf1 is able to bind DNA and luciferase reporter assays demonstrated that Mlf1 is able to affect transcription. In addition, Mlf1 interacts with a novel member of the hnRNP family viz Mlf1 associated nuclear protein (Manp). Manp binds to DNA, is able to influence the subcellular localisation of Mlf1 by translocating Mlf1 from the cytoplasm to the nucleus. Importantly, Manp also has an affect on transcription. These data demonstrate that both Hls5 and Mlf1 affect transcription of genes associated with erythroid differentiation.

Abstract:
In 2009 we hold anniversaries for many composers, for example G.F.Händel, Henry Purcell, J.Haydn and Felix Mandelssohn-Bartholdy. In this abundance of celebrations we should not overlook the 50th anniversaryof Bohuslav Martinů´s death. Czech composer B. Martinů ( 1890 - 1959) was one of the most prolific composers of the 20th century. He was born and grew up in Polička . In 1923 he left his country of birth to study with Albert Roussel in Paris, where he lived for the next 17 years. In 1941 he emigrated to the States, fleeing the German invasion of France. He wrote for leading American orchestras in the following decade. He became homesick bud he never returned to his homeland. Martinů spent his later years in Switzerlandand and he died at age of 69 in Liestal. He wrote almost 400 pieces ( symphonies, operas, ballet and a large number of orchestral, chamber, vocal and vocal- instrumental works). His Epic of Gilgamesh, Field Mass, The Opening of the Wells, and his operas Julietta and The Greek Passion are highly regarded. His music displays a wide variety of influences ( expressionism, constructivism,hazz) and often reflects sensitivy to Czech folk music. Ot is characterized by the freedom of its melodies, the vigor of its rhythms, and the transparency of its textures. This diploma thesis deals of Martinů ´s little known one-act radio opera The Voice of the Forest ( Hlas Lesa). The libretto of the opera is written by the czech poet Vítězslav Nezval. This short experimental work was written specifically for radio performance in 1935. It called for a good articulation and different treatment of dramatic time than would be typical for a staged work. In contrast to the wildy extravagant libretto, the music is fine, lyric and tonal, expressing the characters ´emotions without irony, but with neverending optimism.

This thesis clarifies the elementary terminology on the field of the voice and voice disorders, deals with the problem of voice formation and the function of voice-forming organs and addresses the issue of the influence of voice possibilities and its variability on the artworks. The author of the thesis tries to answer the question why the voice quality and option variability is so decisive for her work. The thesis is divided into three chapters. The first chapter explains the elementary knowledge about voice, the voice-forming organs necessary for voice expression, basic qualities of human voice and its development. The second chapter outlines the issue of voice disorders. The ones mainly described in detail are those which the author of the thesis is subjected to. These disorders are closely related to the artwork analysed in the third chapter. The third chapter addresses the way and level of voice influence over the artwork. The voice variability allowing one's self-reflection through various ways is the key topic. Voice options, their use and artwork impact are also discussed.

Abstract:
The human voice holds a significant position in works of Arnold Schönberg. My dissertation focuses on the use of a voice technique, the so-called Sprechstimme (Spoken-voice) in the musical piece Pierrot Lunaire, op. 21 (1912). I confront the term Sprechstimme with the term Sprechgesang (Spoken-singing) in the very opening of my study. In addition, Schönberg's use of human voice in the pieces written before Pierrot, are briefly mentioned. I am peripherally exploring the other melodramas written by Schönberg, namely Ode to Napoleon Buonaparte, op. 41 (1942) and A Survivor from Warsaw, op. 46 (1947) at the conclusion of this dissertation. I am clarifying why the author has chosen this type of voice technique and also where it is used in musical and aesthetical contexts. I explain the term Sprechmelodie (Spoken-melody) in the area of analysis and focus on the composer's approach to the text material in the ambit of rhythmical component, articulation, dynamics, agogic and the verbal directions for the narrator. Sprechstimme represents one of two fundamental composers approaches towards the human voice and becomes some sort of parallel to the purely vocal composition attitude during the composition time.

Abstract:
[Truncated abstract] Erythropoietin (Epo) is a glycoprotein hormone involved in the formation of erythrocytes, by controlling survival, differentiation and proliferation. The technique of cDNA Representational Difference Analysis was utilized to investigate J2E-NR cells that demonstrate a viability response to Epo, but not differentiation or proliferation. The aim of this project was to identify genes that may be upregulated in response to Epo-induced survival; however, no change in gene expression was detected. This was most probably because any changes were below the limit of detectability for the cDNA RDA technique, or the viability effect was mediated post-transcriptionally. Next, it was decided to investigate HLS5, a putative tumour suppressor that was identified in a myeloid variant of the J2E cell line and had been shown to cause apoptosis. A number of HeLa cell lines inducible for Hls5 expression using the tet-off system were produced; despite extremely low expression, Hls5 was shown to produce marked suppression of growth and proliferation, particularly in colony assays colony size and numbers were halved for one induced clone. … A number of haemopoiesis-associated genes were downregulated (viz. globin genes and the Epo receptor gene), which suggested Hls5s role in the myeloid variant of J2E cells, may be to suppress genes expressed in the erythroid lineage. In addition, several interferon-responsive genes were decreased in cells with elevated HLS5, suggesting it may play a role in negatively regulating interferon signaling. Online databases were also searched for information on HLS5, and showed that it is significantly downregulated in liver, lung and uterine cancers, supporting the proposition that HLS5 is a tumour suppressor gene. In summary, a number of approaches were taken to identify the effects of the Hls5 protein. It appears that it strongly suppresses proliferation and that this is likely mediated through an effect on mitosis. This may also result in apoptosis of overexpressing cells. It is possible that this is the mechanism through which HLS5 exerts its potential tumour suppressor function, as a number of tumour suppressors appear to be associated with mitosis/apoptosis control. Hls5 is also likely to have other functions in haemopoietic cells, which includes downregulation of erythroid-specific genes and suppression of interferon responses.

Abstract:
Hypoplastic left heart syndrome (HLHS) is one kind of serious congenital heart diseases (CHD). With a small, underdeveloped left ventricle, a heart suffering from HLHS cannot effectively supply enough blood flow to provide for the needs of the body. In order to improve blood circulation, surgery for HLHS has to be carried out at a very early stage. In general, three-stage palliative surgical management for newborns is now widely accepted [1, 2]; Norwood, Glenn, and Fontan.

Abstract:
Hypoplastic left heart syndrome (HLHS) is a congenital heart defect (CHD) in which left side of the heart is severely underdeveloped. To better understand this unique physiology, a computational model of the hypoplastic heart was constructed on the basis of compartmental analysis. Lumped parameter model of HLHS is developed based on the electrical circuit analogy. Model is made up of three parts: hypoplastic heart, pulmonary circulation and systemic circulation. Plots of blood pressure and flow for various parts of body show great match between predicted values and what we expected for the case of HLHS babies. Influence of patent ductus arteriosus (PDA) and ASD resistances on cardiac output and pulmonary to systemic flow was also studied. Results show that by increasing the PDA resistance causes more flow to pulmonary compartments and so the ratio increases. Blood flow increases by decreasing of pulmonary artery resistant. Increasing the PDA resistance causes decrease the cardiac output because of more resistance against blood occurs. Saturation increases by decreasing of pulmonary artery resistant.

Abstract:
In mobile hydraulic application the actuating fluid power system is most commonly controlled using a hydro-mechanical control scheme called Hydraulic Load Sensing (HLS). However, with the demands for increased efficiency and controllability the HLS solutions are reaching their limits. Motivated by availability of electronic controllable fluid power components and the potential of increased dynamic performance and efficiency, this paper investigates how HLS can be replaced with electronic control, i.e. Electronic Load Sensing (ELS). The investigation is performed by taking a specific application, a teletruck, and replace the HLS control with ELS. To aid the controller design for the ELS system, a complete model of the teletruck’s articulated arm and fluid power system is developed. To show the feasibility, a preliminary control structure for the ELS system is developed. The controller is tested on the machine, validating that features such as pump pressure control, flow sharing and over pressure protection can be implemented using ELS and with improved energy efficiency.

Abstract:
Pneumatic positioning systems (PPS) are widely used in fields were mechatronics applications exist. In order to improve the performance and robustness, either by designing new controllers or studying other characteristics of PPSs under different load conditions, a test bench with a load simulator is required. Hydraulic load simulators (HLS) are one of the most significant applications of hydraulic force control systems. The HLS aims to control the forces according to static and dynamic requirements. Typically, a force control system interacts with the external environment such that a good performance and robustness are not easily achieved. Different approaches are being discussed in the literature consisting on increasing the system compliance. System compliance can be controlled or modified in active or passive ways. Active compliance is obtained by force-based feedback control, allowing more flexibility to perform tasks where compliance is required. On the other hand, passive compliance is typically obtained by introducing mechanical elastic components between the actuator and the environment. In this paper, the influence of PPS compliance in the force controlled tuning of HLS is discussed. Because HLS is applying a controlled force against to a very compliant system like a pneumatic system, stable force responses could be expected. However, the dynamic interaction between the HLS with the PPS effected the force responses. This paper focuses in analyzing these effects, highlighting the design of PI and QFT controllers for force control based on these characteristics. Both of Systems are analyzed mathematically via simulation.

Abstract:
Hypoplastic left heart syndrome (HLHS) is a congenital heart disease whose staged surgical palliation aims to progressively separate the systemic and pulmonary circulations. The first stage or Norwood procedure [1] involves surgical reconstruction of the aortic arch, usually with pulmonary homograft patch [2]. Recent evidence suggested that, because of this extensive reconstruction, HLHS patients have abnormal elastic properties [3] and reduced distensibility [4,5] of the ascending aorta. However, the impact of the reconstructed aorta and its abnormal elastic properties on ventricular mechanics, i.e. ventriculo-arterial coupling mismatch, has not been assessed. In the light of this mismatch, a change in impedance on the arterial side will reflect on the ventricular side and quantification of this phenomenon may provide mechano-energetic information for further understanding a complex physiology such as palliated HLHS with aortic arch surgical reconstruction. In this study we suggest that wave intensity analysis (WIA) is a valid method for studying ventriculo-arterial coupling, as WIA is a hemodynamic index able to assess the performance of the heart and its interaction with arterial system. Previously, distensibility quantification necessitated either of invasive [5] or cuff [4] arterial pressure monitoring, or multiple magnetic resonance (MR) images acquisitions for transit time wave speed calculation [6]. Instead, here we propose a non-invasive and semi-automated method based only on MR images analysis, with single slice analysis for estimate of local distensibility. The method, including WIA, was developed as a plug-in for DICOM viewer OsiriX, and applied to two cohorts of single ventricle patients.
