description: Additional file 1: Supplementary Figure 1. Successful knock down of microglia using the Csf1R antagonist, PLX5622, given to dams in chow starting at E3.5 onwards. (a) Magnified images from control of Iba1 and Csf1R to view cell morphology and merged imaging. The majority of Csf1R+ cells co-label with Iba1 with rare exceptions (white arrow) that still appear to have a microglial cell morphology. (b) Timeline of microglia knock down model whereby pregnant dams are given PLX5622 or control diet starting at E3.5 and embryonic/postnatal samples were taken at E15.5, E17.5 and P2. (c) In situ hybridization using a csf1r probe to identify mRNA expression in P2 tuberal hypothalamic brain slices in PLX5622 treated and control treated animals. Scattered labeling of cells with csf1r mRNA is seen in the control with some concentration at the ventricle but expression appears to be absent in the PLX5622 model. There is background staining in the PLX5622 sample, but this does not take on the same robust, and cell-like appearance of positive staining seen in the control sample. (d) Control shows both Iba1+ and Csf1R+ cells with microglia-like morphology that are absent in dams treated with PLX5622, which only shows background blood vessel staining. Scale bar = 100μm.
'Speaking to my heart': a close reading of Qohelet as a literary character

description: This project seeks to analyze Qohelet’s first-person speech as a route to understand his character through the words spoken by himself. In scholarship, although Qohelet is recognized as a character, it is often analyzed with the Solomonic figure in Hebrew biblical history or certain social roles from the presumed historical setting of Ecclesiastes. However, Ecclesiastes’ social setting, dating, and authorship are constantly debated as historical evidence are scarce. Therefore, this thesis proposes to reconstruct the Qohelet character by taking the text as literary evidence. It aims to explore the richness of this character by employing the close reading method proposed by New Criticism in English literary studies which continues to influence the way to read a literary text today. It focuses on providing a narrative reading and analysis of the text particularly on passages (1:12-2:26; 3:9-22; 7:15-8:1; and 8:16-9:12) where Qohelet specifically speaks to himself, to his personified heart (לב ,(or to his intended audience. Close reading suggests stripping away any historically authorial and editorial influences on the meaning of the immediate text, and in turn asks how the text may bring out meaning from its content, structure, rhetorical devices, and literary construct by taking the text as a literary unity. Through dissecting the narrative first-person components, the research should show how Qohelet’s character development functions within the text, how the autobiographical voice influences or participates in the meaning of the text, and how these elements simultaneously shape the character of Qohelet and the sapiential theology of the book

description: Superconductivity and the quantum Hall effect are considered to be two cornerstones of condensed matter physics. The realization of hybrid structures where these two effects coexist has recently become an active field of research. In this work, we study a Josephson junction where a central region in the quantum Hall regime is proximitized with superconductors that can be driven to a topological phase with an external Zeeman field. In this regime, the Majorana modes that emerge at the ends of each superconducting lead couple to the chiral quantum Hall edge states. This produces distinguishable features in the Andreev levels and Fraunhofer patterns that could help in detecting not only the topological phase transition but also the spin degree of freedom of these exotic quasiparticles. The current phase relation and the spectral properties of the junction throughout the topological transition are fully described by a numerical tight-binding calculation. In pursuance of the understanding of these results, we develop a low-energy spinful model that captures the main features of the numerical transport simulations in the topological phase.

description: Biomimetic synthesis is a blanket term used to describe a great number of synthetic endeavours, broadly encapsulated by using reactions and materials available during organic metabolism. Herein, we will be utilising biomimicry to interrogate hypotheses for the biogenesis a complex bis-indole natural product; (+)-dievodiamine. As well as this, we will share our attempts to synthesise natural products in a concise way, with high atom economy. Chapter 1 is an introduction to metabolism and the biogenesis of natural products derived from the shikimic acid pathway. Biomimetic syntheses of related natural products will be discussed, as well as a literature review summarising the synthesis of pentacyclic, quinazolinocarboline natural products related to (+)-dievodiamine. The isolation and only known synthesis (+)-dievodiamine will be discussed, as well as our proposed biosynthetic pathway and synthetic plan towards (+)-dievodiamine. Chapter 2 describes the discovery of a unique deprotonation/retro-6π electrocyclisation cascade which supports our proposed biogenesis of (+)-dievodiamine. As well as this, attempts to synthesise (+)-dievodiamine via a vinylogous Mannich reaction are presented, which provides insights into the redox chemistry of evodiamine (the formal monomer of (+)-dievodiamine). Chapter 3 focuses on a route towards (+)-dievodiamine based on nonribosomal peptide synthetase mediated alkaloids. The synthesis of a tri-amide oligomer composed of tryptophan, tryptamine and two units of N-methyl anthranilic acid will be discussed. Beyond that, attempted functionalisation and cyclisation chemistry on a model peptide intermediate will be discussed. Finally, attempts to install a C1-unit within the mature peptide oligomer will be described. Chapter 4 follows-on in our attempts in the synthesis of (+)-dievodiamine by late-stage cyclisation, described in the chapter prior. This strategy we labelled the convergent route, it focuses on a synthesis of (+)-dievodiamine from a pre-functionalised the oligomer from Chapter 3. We will also show that some of the chemistry attempted prior can be achieved simply by removal of a methyl group from the intermediate. We will attempt to complete the synthesis of the natural product through a Pictet−Spengler cyclisation and late-stage ring closure.

title: Comparative approaches to genome evolution in Blastocystis and Entamoeba
Creators: name: Low, RS
Publisher: name: University of Liverpool Repository

description: Parasitism has arisen independently in numerous lineages of eukaryotes. Investigating the origins of parasitism is a core question in evolutionary biology and allows identification of parasite-specific factors that aid in diagnosis and treatment. Comparative genomic studies have often been applied within clades of parasites, which allows their ancestral state to be imagined, but cannot elucidate the processes that surrounded the emergence of parasitism. This question must be approached by comparison with a free-living out-group, to reconstruct the ancestral non-parasitic state. In this thesis, I examine free-living relatives of two intestinal protists of global importance, Blastocystis sp. and Entamoeba histolytica, to explore their evolution. A draft genome sequence for Proteromonas lacertae, the non-pathogenic sister-taxon of Blastocystis, is presented along with a transcriptome for Cafeteria roenbergensis, a free-living out-group to the Blastocystis-Proteromonas clade. Together with the published Blastocystis sp. genome sequences, the P. lacertae genome and the C. roenbergensis transcriptome were used in a comparative genomic analysis. This revealed that the Blastocystis genomes are genuinely small, compared to other Stramenopiles and that this reduction is genome-wide as well as with respect to specific cellular apparatus, such as the flagellum and other motility-associated genes, which have been totally lost from the ancestor of Blastocystis. Rather than observe the same loss of function from metabolic capability, this reduction was associated with loss of gene complexity and is indicative of genomic streamlining. This is coupled with gene family expansion of Ig-like domain-containing proteins, potentially bestowing adhesive qualities to the cell surface. A transcriptome for Mastigamoeba sp., a free-living out-group to the Entamoeba genus, is also presented. The Mastigamoeba sp. transcriptome was used in a comparative analysis of the E. histolytica genome. This analysis revealed large-scale expansion of Ras-family proteins in the ancestor of Entamoeba, which may be linked to motility and phagocytosis required for pathogenesis. Analysis of cathepsins revealed processes of genomic reduction and expansion occurring within the same gene family indicating genomic streamlining and subsequent specialisation in the parasite. I have shown how we might revisit crucial questions in evolutionary biology using the latest genome sequencing technology. By generating new genomic resources for free-living protists, this thesis exposes the mechanism by which two common intestinal parasites of humans and animals evolved. It makes substantial contribution to our understanding of the origins of parasite genomes, and of microbial biodiversity, while revealing numerous parasite-specific features that will sustain future research.

description: The paper presents main results of a surveying 161 tenants whose opinions concerned advantages and disadvantages of renting an agricultural property as well as their motivations for renting agricultural real property from the Agency of Agricultural Real Property and other sources in the province of Warmia and Mazury. Renting real estate belonging to the State Treasury gives an opportunity to enlarge a farm and to obtain the European Union subsidies. Respondents are uncertain about the future farming on the rented land (18,40% of responses). Moreover, the State Treasury agricultural land is poorly maintained (17,60%), has inefficient irrigation and drainage systems (17,60%) and soil in the region is rather poor (5,60%). A lack of precise settlement concerning investment expenditures on the rented land may result in its further degradation. Legislation in Poland lacks provisions for land rentals and the existing regulations referring to this subject are rather of a general nature. The Civil and Agricultural Codes as well as the other regulations applying exclusively to agricultural rentals are in force in the Western European countries where land renting as a form of land management is rapidly becoming more and more popular. / Synopsis.

Badaniami objęto 161 dzierżawców. Dzierżawa pozwala rolnikom powiększyć własne gospodarstwo oraz umożliwia uzyskanie dopłat unijnych. Pomimo wielu udogodnień związanych z tą formą zagospodarowania gruntów Skarbu Państwa nie jest ona wolna od wad. Badani (18,40% odpowiedzi) odczuwają niepewność gospodarowania na dzierżawionym gruncie. Grunty Skarbu Państwa są zaniedbane (17,60% odpowiedzi) i posiadają złe melioracje (17,60%), a dodatkowo gleby na tych terenach są dość słabe (5,60%), brak jest natomiast dokładnych ustaleń odnośnie nakładów inwestycyjnych na przedmiot dzierżawy, co może wpłynąć na dalszą jej degradację. W polskim ustawodawstwie wciąż brakuje przepisów odnoszących się bezpośrednio do dzierżawy, a część obecnych uregulowań prawnych odnosi się do niej dość ogólnikowo. W krajach Europy Zachodniej, w których dzierżawa przeżywa dynamiczny rozwój, oprócz Kodeksu Cywilnego i Rolnego istnieją przepisy odnoszące się wyłącznie do dzierżawy rolniczej.

description: In search of early mentions of the Philippine islands, researchers have referred to Mayi and Butuan as the first polities recorded in Chinese texts. Mayi has gathered special importance because national hero José Rizal (1861-1896) wrote a short piece on the identification of Mayi. All scholars involved in the history of the Philippines agree that Mayi designated a place or region in the Philippines taking their cue from two entries in an official history and an encyclopedia compiled in the fourteenth century, as well as two descriptions in privately compiled works from the early thirteenth and the middle of the fourteenth century. In the following I am arguing firstly, that the earliest Chinese records of Mayi should not necessarily be linked to the later Chinese records; secondly, that Mayi’s location in the tenth century therefore by no means is in the Philippines; and thirdly, that Mayi in the thirteenth century most likely referred to a region that comprised islands in the southern Philippines as well as areas in northern Borneo. One of the major issues with research so far is, that it tends to start with the later texts, such as the Zhufan zhi (1225) and the Wenxian tongkao (1317) while disregarding the earliest sources. This approach certainly obscured some important details that are necessary for the understanding of Mayi and Moyi as two distinct regions in premodern Chinese historiography. Below I am presenting translations of the Chinese texts as well as the research relevant to their understanding, accepting that some readers may view this as superfluous as the same texts have been dealt with exhaustively. However, because their interpretations have not in all cases been reasonable, I venture to submit new critical interpretations.

description: For direct CP-violation in $K\toππ$ decays, the usual isospin-breaking effects at the percent level are amplified by the dynamics behind the $ΔI=1/2$ rule and conventionally encoded in $Ω_{\rm IB}$ parameters. The updated prediction $Ω_{\rm IB}^{(8)}=(15.9\pm 8.2)\times 10^{-2}$ of the Chiral Perturbation Theory for the strong isospin-breaking due to $π_3-η_8$ mixing confirms such a tendency but is quite sensitive to the theoretical input value of the low-energy constant corresponding to the flavour-singlet $η_0$ exchange contribution in this truncated octet scheme. We rather exploit the phenomenological $η_8-η_0$ mixing as a probe for the non-negligible flavour-singlet component of the physical $η$ pole to find $Ω_{\rm IB}^{(9)}=(35\pm7)\times 10^{-2}$ in a complete nonet scheme. A large central value in the nonet scheme is thus substituted for a large uncertainty in the octet one. Including the experimental $π^+-π^0$ mass difference as the dominant electromagnetic isospin-breaking, we obtain for the effective parameter entering the ratio $ε'/ε$ an improved result $\hatΩ_{\rm eff}^{(9)}=(29\pm7)\times 10^{-2}$ to be compared with $\hatΩ_{\rm eff}^{(8)}=(17\pm9)\times 10^{-2}$ used in recent analyses of $ε'/ε$. Accordingly, we get a reduction from $(ε'/ε)_{\rm SM}^{(8)}=(17.4\pm 6.1)\times 10^{-4}$ to $(ε'/ε)_{\rm SM}^{(9)}=(13.9\pm 5.2)\times 10^{-4}$ and thereby an effective suppression of $(ε'/ε)_{\rm SM}$ by isospin-breaking corrections as large as $40\%$ relative to the recent RBC-UKQCD value.

title: The effects of development and virulence on gene expression in the protozoan parasite Neospora caninum
Creators: name: Unjit, KITTICHAI
Publisher: name: University of Liverpool Repository
Year: 2018

description: Neospora caninum is an obligate intracellular protozoan parasite which causes abortion in cattle and neuromuscular disease in dogs. Neosporosis causes substantial economic losses in both dairy and beef cattle industries worldwide. This thesis explores changes in genes and proteins expression associated with development and virulence of N. caninum in order to gain more biological information in this parasite. To achieve the global quantification of genes and proteins expression under different phenotypic conditions, transcriptomics and proteomics approaches are used to investigate these phenomenons. Chapter 2 examines the differential protein expression during tachyzoites-bradyzoites stage conversion using a label-free proteomics approach and finds that the differential protein expression of most apical secretory proteins decrease in abundance in bradyzoites stage. In addition, most of proteins associated with parasite motility were also reduced in abundance in bradyzoites. This indicates that proteins associated with host cell adhesion, invasion and gliding motility are down-regulated in the quiescent cyst-forming stage. Chapter 3 compares the transcriptomic profiles of low- and high-virulence N. caninum using RNA-Seq and finds that protein phosphatase 2C (PP2C) was preferentially expressed in the high-virulence strain, while a group of SRS family proteins was preferentially expressed in low-virulence conditions. This finding suggests that PP2C might play a role in virulence, while a group of SRS proteins might be associated with to limiting N. caninum virulence. Chapter 4 compares protein expression in low- and high-virulence N. caninum strains at three different time points using a label-free quantitative proteomic approach and finds that Rop24 was preferentially expressed in high-virulence N. caninum at all time points. Proteins associated with host cell attachment such as SAG3, TgSRS35A and cathepsin C2 also showed preferentially expression throughout the time course. This finding indicates that Rop24 might be associated with the N. caninum virulence, while the discovery of proteins associated with host cell attachment in low-virulence conditions might suggest that such strains are more efficient in invading host cells than high-virulence strains. Overall, this thesis identifies genes and proteins such as the rhoptry associated proteins PP2C and Rop24, which might be associated with virulence in neosporosis. It also shows that many proteins involved in host cell adhesion, invasion and parasite movement decrease in abundance in the cyst-forming bradyzoite stage. These discoveries enhance our understanding of parasite biology, providing a basis for future research into novel ways to prevent and control the disease by inhibiting parasite survival and transmission.

description: Fabricating van der Waals (vdW) bilayer heterostructures (BL-HS) by stacking the same or different two-dimensional (2D) layers, offers a unique physical system with rich electronic and optical properties. Twist-angle between component layers has emerged as a remarkable parameter that can control the period of lateral confinement, and nature of the exciton (Coulomb bound electron-hole pair) in reciprocal space thus creating exotic physical states including moiré excitons. In this review article, we focus on opto-electronic properties of excitons in transition metal dichalcogenide (TMD) semiconductor twisted BL-HS. We look at existing evidence of moiré excitons in localized and strongly correlated states, and at nanoscale mapping of moiré superlattice and lattice-reconstruction. This review will be helpful in guiding the community as well as motivating work in areas such as near-field optical measurements and controlling the creation of novel physical states.

description: Pr$_{1-x}$Ca$_x$Ba$_2$Cu$_3$O$_{7-δ}$($x\approx$0.5) thin films have been grown on SrTiO$_3$ and YSZ substrates by the pulsed laser ablation. The substrate temperature dependence of orientation and superconducting poperties were systematically studied. Good quality \textit{c} and {a}-axis orientated films can be obtained on SrTiO$_3$ via changing the substrate temperature solely. On YSZ, films with good \textit{c}-axis orientation can be grown, while it is hard to grow films with good \emph{a}-axis orientation by changing substrate temperature alone. The highest $T_{C0}$ is about 37K, which is found in the films grown on YSZ with a good \emph{c}-axis orientation. For the films grown on STO, however, the highest $T_{C0}$ is about 35.6K with a mixed orientation of \emph{c}-axis and \emph{a}-axis. In most of the superconducting films, the weak temperature dependence of the normal state resistivity, as characterized by small $R(290K)/R(50K)\leq2$ ratios, together with a weak localization behavior just above $T_C$ could be attributed to the essential scattering due to the localized electronic states. The superconducting transitions in a field up to 10 T along \textit{c}-axis have been measured on a \textit{c}-axis oriented film grown on SrTiO$_3$. The zero-temperature in-plane upper critical field $B^{ab}_{C2}$(0) is estimated from the resistivity transition data.

description: The spin-triplet state is most likely realized in uranium ferromagnetic superconductors, UGe2, URhGe, UCoGe. The microscopic coexistence of ferromagnetism and superconductivity means that the Cooper pair should be realized under the strong internal field due the ferromagnetism, leading to the spin-triplet state with equal spin pairing. The field-reinforced superconductivity, which is observed in all three materials when the ferromagnetic fluctuations are enhanced, is one of the strong evidences for the spin-triplet superconductivity. We present here the results of a newly discovered spin-triplet superconductor, UTe2, and compare those with the results of ferromagnetic superconductors. Although no magnetic order is found in UTe2, there are similarities between UTe2 and ferromagnetic superconductors. For example, the huge upper critical field exceeding the Pauli limit and the field-reentrant superconductivity for H || b-axis are observed in UTe2, URhGe and UCoGe. We also show the specific heat results on UTe2 in different quality samples, focusing on the residual density of states in the superconducting phase.

description: Rare kaon decays with missing energy, $K\toπ$+$E_{\rm miss}$, have received considerable attention because their rates can be calculated quite precisely within the standard model (SM), where the missing energy is carried away by an undetected neutrino-antineutrino pair. Beyond the SM, clean theoretical predictions can also be made regarding these processes. One such prediction is the so-called Grossman-Nir (GN) bound, which states that the branching fractions of the $K_L$ and $K^+$ modes must satisfy the relation $\mathcal{B}(K_L\toπ^0$+$E_{\rm miss})\lesssim4.3\,\mathcal{B}(K^+\toπ^+$+$E_{\rm miss})$ and applies within and beyond the SM, as long as the hadronic transitions change isospin by $ΔI=1/2$. In this paper we extend the study of these modes to include new-physics scenarios where the missing energy is due to unobserved lepton-number-violating neutrino pairs, invisible light new scalars, or pairs of such scalars. The new interactions are assumed to arise above the electroweak scale and described by an effective field theory. We explore the possibility of violating the GN bound through $ΔI=3/2$ contributions to the $K\toπ$ transitions within these scenarios and find that large violations are only possible in the case where the missing energy is due to an invisible light new scalar.

description: The European Commission has already adopted or will in the future adopt the following acts influencing the market of plant protection products: 1) Thematic strategy on the sustainable use of pesticides; 2) Directive of the European Parliament and of the Council establishing a framework for community action to achieve a sustainable use of pesticides; 3) Regulation of European Parliament and of the Council concerning the placing of plant protection products on the market. These legal documents will influence significantly the member states’ market of plant protection products. The changes will be noticeable in about three years. The biggest influence will probably have the zonal registration. In the next years we can expect a decrease in diversity of plant protection products and an increase of their prices. It is doubtful if the change of EU requirements will cause a decrease in the use of plant protection products in European Union in the nearest future. / Synopsis. Komisja Europejska już przyjęła lub przyjmie w przyszłości następujące dokumenty wywierające wpływ na rynek środków ochrony roślin: 1) Strategia tematyczna w sprawie zrównoważonego stosowania pestycydów; 2) Dyrektywa Parlamentu Europejskiego i Rady ustanawiająca ramy wspólnotowego działania na rzecz osiągnięcia zrównoważonego stosowania pestycydów; 3) Rozporządzenie Parlamentu Europejskiego i Rady dotyczące wprowadzania do obrotu środków ochrony roślin. Przewidywany jest duży wpływ tych dokumentów na rynek środków ochrony roślin w państwach członkowskich. Zmiany będą widoczne za około 3 lata. Największy wpływ na rynek środków ochrony roślin będzie miała prawdopodobnie rejestracja strefowa. W najbliższych latach można się spodziewać zmniejszenia różnorodności stosowanych środków ochrony roślin oraz wzrostu ich cen. Wątpliwe jest, czy nowelizacja wymagań unijnych doprowadzi do obniżenia zużycia środków ochrony roślin w Unii Europejskiej w najbliższej przyszłości.

description: The gravitational collapse of cylindrically distributed perfect fluid is studied. We assume the collapsing speed of fluid is very large and investigate such a situation by recently proposed high-speed approximation scheme. We show that if the value of the pressure divided by the energy density is bounded below by some positive value, the high-speed collapse is necessarily halted. This suggests that the collapsing perfect fluid of realistic ideal gas experiences the pressure bounce. However even in the case of mono-atomic ideal gas, arbitrarily large tidal force for freely falling observers are realizable by setting the initial collapsing velocity exceedingly large. In order that the high-speed collapse of cylindrical perfect fluid forms spacetime singularity, the equation of state should be very soft.

Glutathione in fish : transport, influence of temperature and growth rate, and interaction with the stress response
Creators: name: Leggatt, Rosalind Alexandra
Publisher: name: University of British Columbia
Year: 2010

description: Glutathione (GSH) is a ubiquitous antioxidant involved in many cellular processes in mammals. In contrast, fish have relatively low GSH levels, as well as low turnover and activity of associated enzymes. As the metabolism and function of GSH have been poorly studied in fish, I examined the mechanisms by which fish tissues transport GSH, the influence acclimation temperature and growth rate have on GSH dynamics, and the importance of GSH during heat stress in fish to elucidate the differing roles of GSH in fish and mammals. In Chapter 2 I demonstrated that posterior kidney, and to a lesser extent liver and gill, of rainbow trout took up GSH by extracellular breakdown and intracellular synthesis. Direct uptake of exogenous GSH was observed in the liver as apparent gradient-dependent transport. In Chapter 3 I demonstrated that GSH turnover was proportional to incubation temperature in a rainbow trout hepatoma cell line in vitro. In killifish in vivo, tissue GSH levels and activity of GSH-associated enzymes were proportional to acclimation temperature. Although these experiments showed that temperature influences GSH dynamics in fish, the effects of temperature could only partially explain the low GSH levels in fish compared with mammals. In Chapter 4 I showed that high GSH levels and activity of associated enzymes in growth hormone transgenic coho salmon with high metabolic rates were due to increased feeding and growth rather than to direct effects of the transgene. Oxygen consumption corresponded to liver GSH levels in control and transgenic fish, but not to other components of the GSH system. Although long-term changes in temperature influenced GSH dynamics in killifish, in Chapter 5 I demonstrated that acute temperature changes had little effect on GSH dynamics in rainbow trout in vivo or in vitro. However, altered GSH levels inconsistently altered the cellular response to acute heat stress in rainbow trout in vitro, and influenced the generalized and cellular responses to acute heat stress in vivo. Taken together, these studies demonstrate that fish can substantially modulate GSH levels in response to demand, and that altered GSH levels influence other physiological systems.

description: In this study, we reported our exploration of Text-To-Speech without Text (TTS without T) in the Zero Resource Speech Challenge 2020, in which participants proposed an end-to-end, unsupervised system that learned speech recognition and TTS together. We addressed the challenge using biologically/psychologically motivated modules of Artificial Neural Networks (ANN), with a particular interest in unsupervised learning of human language as a biological/psychological problem. The system first processes Mel Frequency Cepstral Coefficient (MFCC) frames with an Echo-State Network (ESN), and simulates computations in cortical microcircuits. The outcome is discretized by our original Variational Autoencoder (VAE) that implements the Dirichlet-based Bayesian clustering widely accepted in computational linguistics and cognitive science. The discretized signal is then reverted into sound waveform via a neural-network implementation of the source-filter model for speech production.

description: A kockázatitőke-befektetések jelentős hatással vannak a gazdaság növekedésére, mivel megkeresik és finanszírozzák az innovatív és gyors növekedési potenciállal rendelkező fiatal vállalkozásokat. A kockázati tőkéről szóló aktuális globális trendekből szembetűnő különbségek vonhatók le országok/régiók között. A kockázati tőke aktivitásának globális szintű megoszlása 2013-ban a következő: közel 70 százalék az Egyesült Államokban, 15 százalék Európában, és közel 11 százalék ázsiai országokban valósult meg. A tanulmány egyik célja, hogy bemutassuk milyen fejlődési utat jártak be a kiemelt területek (Egyesült Államok, Németország és Délkelet- Ázsia) kockázatitőke-piacai, és ebből keressük azokat a magyarázó tényezőket, amelyek hatással vannak az adott ország kockázati tőke aktivitására. Az összehasonlító módszer alapján meghatározó faktoroknak tekinthető például a pénzügyi rendszer fejlettségi szintje, a finanszírozási kultúra, a gazdasági és jogi környezet. A tanulmány másik célja, hogy egyrészről megvizsgáljuk, miben rejlik az amerikai kockázati tőke sikere, másrészről ezen sikertényezőket mennyire tudják alkalmazni más országokban. Az amerikai kockázatitőke-piac sikertényezőiként említhető a magvető fázisra törekvés, a hazafutás és a hozzáadott érték szemlélet. ------------------------------------------- Venture capital investments have a significant impact on economic growth because the venture capitalists find and finance innovative and rapidly growing young enterprises. Based on current global trends about venture capital striking differences can be drawn between countries / regions. The distribution of venture capital activity at global level in 2013 was the following: nearly 70 percent in the United States, 15 percent in Europe, and nearly 11 percent in Asian countries. One aim of the study is to present the different development ways of venture capital markets in the priority areas (United States, Germany and South-East Asia), and therefore we find the explanatory factors that have an impact on a country's venture capital activity. Based on the comparative method we find out that the development level of the financial system, the financing culture, and the economic and the legal environment are the main determining factors. Another aim of the study is to examine on one hand, what is the success of the US venture capital model, on the other hand, how these success factors can be adapted to other countries. The US venture capital market’s success characters include the financing of seed phase, a home run and the value-added approach.

description: We investigate spectral features of the Dirac operator with infinite mass boundary conditions in a smooth bounded domain of $\mathbb{R}^2$. Motivated by spectral geometric inequalities, we prove a non-linear variational formulation to characterize its principal eigenvalue. This characterization turns out to be very robust and allows for a simple proof of a Szegö type inequality as well as a new reformulation of a Faber-Krahn type inequality for this operator. The paper is complemented with strong numerical evidences supporting the existence of a Faber-Krahn type inequality.

Correcting for the alias effect when measuring the power spectrum using FFT
Creators: name: Jing, Y. P.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Because of mass assignment onto grid points in the measurement of the power spectrum using the Fast Fourier Transform (FFT), the raw power spectrum $\la |δ^f(k)|^2\ra$ estimated with FFT is not the same as the true power spectrum $P(k)$. In this paper, we derive the formula which relates $\la |δ^f(k)|^2\ra$ to $P(k)$. For a sample of $N$ discrete objects, the formula reads: $\la |δ^f(k)|^2\ra=\sum_{\vec n} [|W(\kalias)|^2P(\kalias)+1/N|W(\kalias)|^2]$, where $W(\vec k)$ is the Fourier transform of the mass assignment function $W(\vec r)$, $k_N$ is the Nyquist wavenumber, and $\vec n$ is an integer vector. The formula is different from that in some of previous works where the summation over $\vec n$ is neglected. For the NGP, CIC and TSC assignment functions, we show that the shot noise term $\sum_{\vec n} 1/N|W(\kalias)|^2]$ can be expressed by simple analytical functions. To reconstruct $P(k)$ from the alias sum $\sum_{\vec n}|W(\kalias)|^2 P(\kalias)$, we propose an iterative method. We test the method by applying it to an N-body simulation sample, and show that the method can successfully recover $P(k)$. The discussion is further generalized to samples with observational selection effects.

description: This article draws on the terminology of Günther Anders to identify three different forms of crisis in contemporary society: the crisis of  freedom, the crisis of humanity as subject of history, and the crisis  of shame. The article is composed of three different sections. The  first section analyses Anders’ early anthropological works to show how freedom has turned into its own negation. The second section  examines the other two types of crisis revolving around Anders’ notion  of Promethean shame and techné. Building on these discussions, the final section offers an open suggestion for  re-thinking the possibility of redeeming human action within the  technological determinism of our epoch via an Andersian-inspired hypothesis.
