description: This paper presents a novel measurement
system for derivative extraction under dynamic conditions
based on the utilization of pulsed signals. This kind of
characterization avoids unrealistic heating and trapping
effects, making possible to realize the extraction process
under conditions as close as possible to the device RF
behaviour. The system principles and set-up are presented
and described in order to provide reliable device modelling.
Moreover, results of the derivative extraction process for an
FLL177ME MESFET are presented with the aim of
highlighting the existing differences between pulsed and
traditional DC derivative characterization.
A novel wideband MMIC voltage controlled attenuator with a bandpass filter topology

Subjects: ING-INF/01 Elettronica

description: The design and analysis of a novel wideband,
monolithic, bandpass, π-network, voltage controlled
attenuator (VCA) is presented. A 24 to 32 GHz VCA was
developed using 0.15μm GaAs pHEMT technology. This is
the first reported VCA to use a bandpass filter topology to
achieve the required operating frequency band and
eliminate the effects of parasitic capacitances of the
pHEMTs. The bandpass filter absorbs the parasitic
capacitances and thereby eliminates their detrimental
effects.
The measured attenuation dynamic range is 12dB ± 0.5dB
with minimum insertion loss of 2-3dB. The input power
handling capability is up to 0dBm. The VCA is well
matched and may be placed in a 50Ω system [1].

description: In the framework of large deformation diffeomorphic metric mapping (LDDMM), we develop a multi-scale theory for the diffeomorphism group based on previous works. The purpose of the paper is (1) to develop in details a variational approach for multi-scale analysis of diffeomorphisms, (2) to generalise to several scales the semidirect product representation and (3) to illustrate the resulting diffeomorphic decomposition on synthetic and real images. We also show that the approaches presented in other papers and the mixture of kernels are equivalent.

description: Danaparoid ist als Antikoagulans bei bestehender Heparin-induzierter Thrombozytopenie (HIT) zugelassen und stellt für Patienten mit einer HIT und mechanischem Herzklappenersatz oder notwendiger perkutaner Koronarintervention (PCI) eine Alternative zu den Heparinen dar. Ziel der Arbeit war ein Vergleich der Effektivität von Danaparoid mit unfraktioniertem Heparin (UFH) und Enoxaparin bezüglich der Thrombusvermeidung an mechanischen Herzklappen sowie Herzkathetern, wofür zwei mit antikoaguliertem Blut perfundierte in-vitro-Modelle genutzt wurden. Danaparoid zeigte im Vergleich zu den Heparinen eine bessere Wirkung an mechanischen Herzklappen, wohingegen die ermittelten Thrombusgewichte in den Herzkathetern unter Danaparoid erhöht waren. Es sollte deshalb im Rahmen einer PCI nur mit Vorsicht eingesetzt werden. Bei guter Effektivität im Herzklappenmodell erscheint es hingegen sinnvoll, die Wirksamkeit und Sicherheit dieser Substanz für Patienten mit mechanischem Herzklappenersatz zu prüfen.
description: Patients who develop heparin-induced thrombocytopenia (HIT) while receiving unfractionated heparin (UFH) need another anticoagulation, especially when requiring percutaneous coronary intervention or having a mechanical heart valve in situ. This study compares the anticoagulant effect of danaparoid, UFH and enoxaparin on preventing thrombus formation at mechanical heart valves and in cardiac catheters by using two in-vitro systems. Danaparoid was superior to UFH and enoxaparin in preventing thrombus formation at mechanical heart valves as thrombus weight was lowest in the danaparoid group, whereas thrombus formation in cardiac catheters was increased using danaparoid as compared to UFH und enoxaparin. These results suggest that danaparoid is not as effective as UFH and enoxaparin in preventing cardiac catheter thrombosis while it seems to be a potent alternative to UFH in patients with mechanical heart valve replacement and HIT, which is worth further studies.

description: The investigation of post-AGB objects (proto-planetary nebulae) is very important from the standpoint of physical and chemical changes occurring during the late stages of stellar evolution. The Toruń catalogue of Galactic post-AGB and related objects is an evolutive catalogue containing astrometric, photometric and spectroscopic data as well as HST images for all known post-AGB objects and candidates in our Galaxy. This free-access catalogue can serve as an ideal tool to study different groups of post-AGB objects, especially due to the fact that all information is gathered in one place. The second release of our catalogue introduces a simple classification scheme of post-AGB objects and includes a significant number of new objects, photometric data, spectra and images. Here, using objects from the catalogue we consider the problem of the termination of the AGB phase.

description: We discuss some of the issues that arise when considering the physics of asymptotically de Sitter spacetimes, and attempts to address them. Our development begins at the classical level, where several initial value problems are discussed, and ends with several proposals for holography in asymptotically de Sitter spacetimes. Throughout the paper we give a review of some basic notions such as the geometry of the Schwarzschild-de Sitter black hole, the Nariai limit, and quantum field theory in a fixed de Sitter background. We also briefly discuss some semiclassical aspects such as the nucleation of giant black holes and the Hartle-Hawking wavefunctional. We end by giving an overview of some open questions. An emphasis is placed on the differences between a static patch observer confined to live in a thermal cavity and the metaobserver who has access to a finite region of the future boundary.

description: We compare the structural properties of galaxies formed in cosmological simulations using the smoothed particle hydrodynamics (SPH) code GADGET with those using the moving-mesh code AREPO. Both codes employ identical gravity solvers and the same sub-resolution physics but use very different methods to track the hydrodynamic evolution of gas. This permits us to isolate the effects of the hydro solver on the formation and evolution of galactic gas disks in GADGET and AREPO haloes with comparable numerical resolution. In a matching sample of GADGET and AREPO haloes we fit simulated gas disks with exponential profiles. We find that the cold gas disks formed using the moving mesh approach have systematically larger disk scale lengths and higher specific angular momenta than their GADGET counterparts across a wide range in halo masses. For low mass galaxies differences between the properties of the simulated galaxy disks are caused by an insufficient number of resolution elements which lead to the artificial angular momentum transfer in our SPH calculation. We however find that galactic disks formed in massive halos, resolved with 10^6 particles/cells, are still systematically smaller in the GADGET run by a factor of ~2. The reasons for this are: 1) The excessive heating of haloes close to the cooling radius due to spurious dissipation of the subsonic turbulence in GADGET; and 2) The efficient delivery of low angular momentum gaseous blobs to the bottom of the potential well. While this large population of gaseous blobs in GADGET originates from the filaments which are pressure confined and fragment due to the SPH surface tension while infalling into hot halo atmospheres, it is essentially absent in the moving mesh calculation, clearly indicating numerical rather than physical origin of the blob material.

description: T/R modules are the key components for active phased array radar applications. This paper describes light-weight, temperature compensated T/R modules which have been developed at DaimlerChrysler Aerospace within the last months. The presented T/R modules are characterised by a three dimensional temperature compensation algorithm, light weight, and high efficiency, which are the main features for T/R modules used in space-borne applications. Besides highly sophisticated Gallium Arsenide monolithic microwave integrated circuits (GaAs MMICs), the key components for T/R modules, multilayer alumina (A12O3) substrate technology has been applied to reduce module size and weight. The presented T/R modules are controlled by a highly integrated digital control electronics realised in MCM-D technology, i.e. multi chip module using bare chips on alumina substrate in thinfilm technology, in which the compensation algorithm is contained, and which is able to control two T/R elements independently, each consisting of one Tx and Rx channel. Applying these technologies, small-sized and light-weight duopack T/R modules have been built-up.

description: A high efficient, low distortion L-band power module using a linear and non-linear models of the HFET devices has been developed. Single stage hybrid amplifier fabricated with 4x18mm gate width HFET exhibits an output power of 43.8dBm, a linear gain of 17dB and an associated PAE of 60% at 1.5GHz. These excellent results are performed by developing an accurate non-linear model of the chip device and optimizing the matching networks of the amplifier.

description: Die Quantifizierung der myokardialen Einschränkung im Rahmen der septischen Kardiomyopathie ist bis heute eine Herausforderung. Mit Berechnung der „Afterloadrelated Cardiac Performance“(ACP) konnten rühere Untersuchungen einen guten prädiktiven Wert finden. Ziel der vorliegenden Dissertationsarbeit war es den Einfluss der Katecholamintherapie auf die prognostische Aussagekraft des ACP bei kritisch kranken Patienten mit Sepsis zu untersuchen. Es wurden prospektiv, monozentrisch 137 Patienten einer internistischen Intensivstation über einen Zeitraum von 15 Monaten untersucht und in 2 Gruppen anhand eines Katecholaminscores eingeteilt. Die Messung der Hämodynamikparameter erfolgte mittels Pulmonalarterienkatheter oder PiCCO-System. Patienten mit Hochdosiskatecholamintherapie in der Sepsis hatten eine schlechtere Herzleistung und ungünstigere Prognose. Der ACP bei Patienten der Hochdosiskatecholamingruppe war signifikant niedriger als bei Patienten der Niedrigdosis-Gruppe (70 % vs. 78 %). Neben der Katecholamindosierung erwies sich das Patientenalter als signifikanter Einflussfaktor auf den ACP am Tag 1.
description: Quantifying the myocardial function in septic cardiomyopathy is still a challenge today. With the "afterload-related cardiac performance" (ACP) previous studies were able to find a good predictive value of calculating cardiac output in relation to the systemic vascular resistance. Our aim was to investigate the influence of catecholamine therapy on the prognostic value of the ACP in critically ill patients with sepsis. In a prospective, monocentric observation study 137 patients were examined over a period of 15 months in an internal intensive care unit and divided into 2 groups using a catecholaminscore. The hemodynamic parameters were measured using pulmonary artery catheter or PiCCO system. Patients with high-dose catecholamine therapy in sepsis had a poorer heart performance and higher in-hospital mortality. The ACP in patients of the high-dose catecholamine group was significantly lower than in patients with low-dose catecholamine therapy (70% vs. 78 %). In addition to catecholamine dosage the patients age proved to be a significant influencing factor on the ACP on day 1.

description: We present a laser frequency comb based upon a 250 MHz mode-locked erbium-doped fiber laser that spans more than 300 terahertz of bandwidth, from 660 nm to 2000 nm. The system generates 1.2 nJ, 70 fs pulses at 1050 nm by amplifying the 1580 nm laser light in Er:fiber, followed by nonlinear broadening to 1050 nm and amplification in Yb:fiber. Extension of the frequency comb into the visible is achieved by supercontinuum generation from the 1050 nm light. Comb coherence is verified with cascaded f-2f interferometry and comparison to a frequency stabilized laser.

Defining the complex interactions between the intestinal microbiota, mucus secretion, and infection
Creators: name: Wlodarska, Marta
Publisher: name: University of British Columbia

description: Inflammatory bowel disease (IBD) is a debilitating disease characterized by chronic inflammation caused by multiple factors involving the immune system, intestinal microbiota and epithelial barrier. Microbial dysbiosis is implicated in disease, as there are significant differences in the microbiota composition between affected and healthy individuals. It is not clear if deterioration of microbial composition results in disease or is a consequence of disease. Mucus production by goblet cells serves as one of the crucial mucosal defenses at the interface between the eukaryotic and prokaryotic cells and yet the immunoregulatory pathways involved remain uncharacterized. The inner mucus layer of the intestine functions as a barrier, which serves to minimize microbial translocation, prevents excessive immune activation, and decrease infection. Here we have described methodology to alter the thickness of the inner mucus layer through treatment with antibiotic or a phytonutrient. We showed that the antibiotic metronidazole caused significant thinning of the inner mucus layer accompanied by a dramatic change in the microbial community structure. In contrast, treatment with the phytochemical eugenol resulted in significant thickening of the inner mucus layer that was accompanied by a change in the microbial community. These changes in community structure were complementary; DNA sequencing showed that groups depleted by metronidazole treatment were more abundant with eugenol treatment. To investigate how changes in the integrity of the inner mucus layer affect intestinal defense, Citrobacter rodentium (Cr) was used to examine susceptibility to enteric-induced colitis. Metronidazole-induced reduction in mucus thickness correlated with exacerbated severity of Cr-induced colitis. Thickening of the inner mucus layer with eugenol treatment resulted in protection from Cr-induced colitis. Further, we identified a novel innate immune pathway involved in regulation of goblet cell function and mucus layer production. The NLRP6 inflammasome was shown to regulate mucus secretion and deficiency in any component of the NLRP6 inflammasome resulted in impaired goblet cell function preventing mucin granule exocytosis and mucus layer formation. Abrogated mucus secretion led to increased invasiveness and pathology of Cr infection. Mechanistically, NLRP6 deficiency led to stalled autophagy in goblet cells, providing a link between inflammasome activity, autophagy, mucus exocytosis, and antimicrobial barrier function.

description: An X-band high power Solid-State Power Amplifier (SSPA) using power HFET chip devices has been successfully developed for the earth observation satellite payload of the SPOT 5 program. The use of MMIC chips for the low power section allows to decrease significantly the mass and the size of this equipment and to reduce the production cycle due to the reduced tuning effort. The hybrid technology is used in the driver module and the power level section because it is attractive in terms of power and efficiency performances. This SSPA exhibits an output power of 22 watts with DC power consumption less than 91VV. The output power is regulated by an ALC loop for input power between -20dBm and +15dBm.

description: Die Diagnostik eines Prostatakarzinoms (PCa) mittels systematischer Biopsie (SB) und gezielter MRT/Ultraschall-Fusionsbiopsie (FB) hat zu einer Steigerung der Detektionsrate des PCa geführt (1). Durch zusätzliche gezielte Probeentnahmen steigt jedoch die Gesamtanzahl der Biopsien. Ziel dieser Arbeit ist die Definition von Prädiktoren, die dabei helfen Männer zu identifizieren, bei denen die ausschließlich gezielte Biopsie (FB) für eine sichere Risikoevaluierung des PCa ausreicht. Es erfolgte eine retrospektive Analyse von 325 Männern (03/2016 – 01/2018), bei denen eine kombinierte FB und SB der Prostata durchgeführt wurde. Mittels uni- und multivariater logistischer Regression wurden mögliche Prädiktoren für eine alleinige FB überprüft: Prädiktoren der univariaten Analyse [Alter (OR 1,06; p = 0,004); f/t-PSA (OR 0,94; p = 0,01); Suspekte digital rektale Untersuchung (DRU) (OR 2,41; p = 0,02); PI-RADS von 4 oder 5 (OR 4,31; p = 0,001)] beziehungsweise der multivariaten Analyse [f/t-PSA (OR 0,91; p = 0,002); PI-RADS von 4 oder 5 (OR 4,2; p = 0,01)]. Mithilfe der ermittelten Prädiktoren erfolgte die Berechnung von vier Prädiktionsmodellen und deren Vergleich. Dabei konnte mittels des zu präferierenden Prädiktionsmodells [Prädiktoren: Alter, suspekte DRU, f/t-PSA und PI-RADS von 4 oder 5; Parameter: AUC (0,752), Sensitivität 78%, Spezifität 69%, pos. prädiktiver Wert 89%] unter Anwendung eines empirischen Cut-off von 74% für eine ausreichende Risikobewertung durch die alleinige FB bei 88% (76/86) der Männer der Index-Tumor diagnostiziert werden. Das Alter, der f/t-PSA, eine suspekte DRU und der PI-RADS-Score scheinen geeignete Prädiktoren für eine suffiziente Risikoevaluierung eines PCa durch ausschließlich gezielte FB der Prostata zu sein.

description: Many problems arising in applications result in the need to probe a probability distribution for functions. Examples include Bayesian nonparametric statistics and conditioned diffusion processes. Standard MCMC algorithms typically become arbitrarily slow under the mesh refinement dictated by nonparametric description of the unknown function. We describe an approach to modifying a whole range of MCMC methods, applicable whenever the target measure has density with respect to a Gaussian process or Gaussian random field reference measure, which ensures that their speed of convergence is robust under mesh refinement. Gaussian processes or random fields are fields whose marginal distributions, when evaluated at any finite set of $N$ points, are $\mathbb{R}^N$-valued Gaussians. The algorithmic approach that we describe is applicable not only when the desired probability measure has density with respect to a Gaussian process or Gaussian random field reference measure, but also to some useful non-Gaussian reference measures constructed through random truncation. In the applications of interest the data is often sparse and the prior specification is an essential part of the overall modelling strategy. These Gaussian-based reference measures are a very flexible modelling tool, finding wide-ranging application. Examples are shown in density estimation, data assimilation in fluid mechanics, subsurface geophysics and image registration. The key design principle is to formulate the MCMC method so that it is, in principle, applicable for functions; this may be achieved by use of proposals based on carefully chosen time-discretizations of stochastic dynamical systems which exactly preserve the Gaussian reference measure. Taking this approach leads to many new algorithms which can be implemented via minor modification of existing algorithms, yet which show enormous speed-up on a wide range of applied problems.

description: L'articolo si propone di indagare le modalità di traduzione, non solo linguistica, e di ricezione di un successo coreografico francese e internazionale in una città italiana ottocentesca, Bologna. L'indagine storiografica e critica intende procedere attraverso il confronto tra il libretto originale di Giselle, pubblicato nel 1841 in occasione della prima rappresentazione dello spettacolo presso il Théâtre de l'Académie royale de musique di Parigi, e la sua versione rivisitata e adattata pubblicata nel 1843 in occasione del debutto di Gisella presso il Teatro Comunale di Bologna, attraverso l’analisi di testimonianze dell’epoca, nonché attraverso un'opportuna contestualizzazione. Lo sguardo strettamente locale viene ampliato grazie all'analisi di alcune ulteriori e coeve versioni del libretto che si collocano alla base di messe in scena realizzate in altre città italiane (Milano, Roma, Firenze) con l'intervento di coreografi come Antonio Cortesi, Domenico Ronzani e Carlo Blasis e con l'interpretazione del ruolo principale da parte di ballerine come Fanny Cerrito, Fanny Elssler e Nathalie Fitzjames, ben note anche sul maggiore palcoscenico parigino.

description: The problem of the determinism of Quantum Mechanics has been a main one during the 20th century. At the same time, in the context of Logic and Set Theory, the importance of ancient paradoxes as well as the appearance of many new ones, has shed light on and deeply influenced the foundations of Mathematics and somehow of Physics. But, strangely, concerning Physics, a paradox which we call the Memory Paradox has remained yet undiscovered, despite its simplicity and remarkable consequences, mostly in Physics and surprisingly in classical Physics that appear to be non deterministic, contrary to the general belief since Newton, Laplace, etc.. The non determinism of Quantum Physics follows without any supplementary hypothesis. This paper extends a previous one (arXiv: 1203.2945v1 [physics.gen-ph] 13 Mar 2012).

description: Information and communication technology prompted the sharing of information over the world. For its impact on education, the government and the authorities like the University Grants Commission in India have energized the higher education institutions in India to implement online education during the pandemic situation. This paper attempts to know the teaching faculties' ICT skills and related online class skills in higher educational institutions in India. In India, like developing countries, quick as the lightning change in traditional to fully online classes are like a rumble of thunder because faculties are adopting this situation but students are challenging to adopt. The directed out of two hundred and twenty respondents were sampled randomly, questionnaires were distributed online, 201 were properly filled and returned from central universities, government higher education institutions, and state universities. A one-way ANOVA and independent-sample t-test on SPSS for data analysis were adopted. The results revealed that the respondents are significantly the same regarding their skills related to online teaching and ICT integration. Online education also involves sharing of resources, reinforcement techniques, questioning, and evaluation. There was a significant difference in ICT skills and ICT integration in online education. This was due to their age, availability of resources and some operational difficulties. Following the present scenario, the right attitude and skills are recommended on the 21st-century requirements. Faculties are how they feel and taking into serious or joy, and an online class is given to their pleasure or pressure are discussed in this article.

RNA-directed DNA methylation). Dazu wurde die Familie der Argonautenproteine (AGO) in Thymian als Kandidaten für diese Regulation näher untersucht. Diese Proteinfamilie wurde zuvor nicht in T. vulgaris beschrieben und spielt möglicherweise eine wichtige Rolle bei der Ausprägung der Chemotypen.
description: Thymus vulgaris, also known as common thyme or garden thyme, produces essential oils that are of use for the pharmaceutical industry. It is known to differentiate into six chemotypes in wild type that are each dominated by a specific monoterpene alcohol: geraniol (G), α-terpineol (A), trans-sabinene hydrate (U), linalool (L), carvacrol (C) und thymol (T). The inheritance of the chemotypes is regulated via at least five different alleles and form an epistatic row. In this work, methylation was implicated in the the control of biosynthetic genes and formation of the chemotypes, suggesting that RdDM (RNA-directed DNA methylation) may be an important mechanism. Therefore a key component of RdDM, the family of the Argonaute proteins (AGO) was investigated. This protein family has not yet been described in Thymus vulgaris and may play an important role in gene expression control in this model system.

description: Il saggio indaga alcune modalità compositive proprie del balletto dell’Ottocento approfondendo in particolare il ruolo che rivestono il librettista, il coreografo e il danzatore nella creazione coreografica; la prassi di impiegare un vocabolario e una sintassi di movimento fortemente codificati e comunque incorporati dagli interpreti; i confini della libertà di azione di chi ri-crea uno spettacolo di repertorio.
La riflessione si articolerà intorno al caso esemplare di un’opera cardine come Giselle, dal suo debutto, nel 1841,  al Théâtre de l'Opéra di Parigi, fino agli albori del XX secolo e si fonderà sulle considerazioni e sulle testimonianze di artisti e spettatori coevi.

description: Let K be a comonad on a model category M. We provide conditions under which the associated category of K-coalgebras admits a model category structure such that the forgetful functor to M creates both cofibrations and weak equivalences. We provide concrete examples that satisfy our conditions and are relevant in descent theory and in the theory of Hopf-Galois extensions. These examples are specific instances of the following categories of comodules over a coring. For any semihereditary commutative ring R, let A be a dg R-algebra that is homologically simply connected. Let V be an A-coring that is semifree as a left A-module on a degreewise R-free, homologically simply connected graded module of finite type. We show that there is a model category structure on the category of right A-modules satisfying the conditions of our existence theorem with respect to the comonad given by tensoring over A with V and conclude that the category of V-comodules in the category of right A-modules admits a model category structure of the desired type. Finally, under extra conditions on R, A, and V, we describe fibrant replacements in this category of comodules in terms of a generalized cobar construction.

subject: http://www.oecd.org/dataoecd/36/44/38235147.pdf

description: This paper presents information on the resulting complete system for indoor location of objects. The resulting system uses the Fingerprinting method to determine the location, basing on the Electronically Steerable Parasitic Array Radiator (ESPAR antenna) and a smartphone serving as a mobile broadcast station. The antenna covers the space around itself, by switching configurations and receiving information about the strength of the signal received from the phone.
 The diploma thesis contains, among other things, information about the antenna used in the project, the Bluetooth standard used and the implemented fingerprinting method. The process of creating an algorithm simulating the operation of the antenna and the one controlling it, as well as the problems encountered during the creation of the code was also described.
 The complete system was tested at home using the telephone as a localized object. The phone's antenna was controlled by a generally available application recommended by the manufacturer of the electronic board used in the ESPAR antenna.
 A series of measurements was made in various conditions in the room, resulting in confirmation of the correctness of the system operation and noting the influence of many factors on its operation. Measurement results were documented and ways to improve system performance were proposed as well.

description: Neutral stellar core at or over nuclear densities is described by a positive charged baryon core and negative charged electron fluid since they possess different masses and interactions. Based on a simplified model of a gravitationally collapsing or pulsating baryon core, we approximately integrate the Einstein-Maxwell equations and the equations for the number and energy-momentum conservation of complete degenerate electron fluid. We show possible electric processes that lead to the production of electron-positron pairs in the boundary of a baryon core and calculate the number and energy of electron-positron pairs. This can be relevant for understanding the energetic sources of supernovae and gamma-ray bursts.

Molecular beam epitaxy growth technology and properties of GaAsBi alloys
Creators: name: Lewis, Ryan B.
Publisher: name: University of British Columbia
Year: 2014

description: In this thesis, molecular beam epitaxy (MBE) technology and the MBE growth of GaAsBi are investigated. MBE is a non-equilibrium technique whereby precisely controlled molecular beams are deposited onto a heated substrate at temperatures much lower than for equilibrium growth techniques. A novel closed-cycle cooling setup is implemented to replace liquid nitrogen (LN₂) cooling of the MBE cryo-shroud. The temperature dependence of cryopanel pumping is explored, and GaAs and AlGaAs layers grown using the new cooling setup and with LN₂ cooling of the shroud are characterized. Strong AlGaAs photoluminescence and low impurity concentrations indicate closed-cycle cooling is a promising cost-saving technique for MBE. The relatively unexplored III-V-Bi family of alloys is an exciting frontier of III-V semiconductor alloy exploration. The GaAsBi alloy exhibits many novel properties, including an unparalleled bandgap reduction per change in the size of the crystal lattice, presenting a wide range of potential device applications. A systematic study of the dependence of Bi incorporation on MBE growth conditions is presented. Bi incorporation is found to rapidly increase as the As₂:Ga flux ratio is lowered to 0.5 and saturate for lower flux ratios. This indicates Bi incorporation is sensitive to the surface stoichiometry. A GaAsBi growth model is proposed where Bi from a wetting layer incorporates on surface sites which are terminated by Ga. Low growth temperatures are required as the weak Bi-Ga incorporation bond can be broken thermally, ejecting Bi back to the wetting layer. GaAsBi layers with up to 21.8% Bi, record Bi-content, were grown at temperatures as low as 200C. These layers have up to 2.6% mismatch from the GaAs substrates and show unusually large critical thicknesses for relaxation, a result of the low growth temperature. Optical absorption measurements on pseudomorphic GaAsBi layers with up to 18.7% Bi show the bandgap decreases strongly with increasing Bi-content, reaching 0.5 eV at 18.7% Bi. Si-doped n-GaAsBi layers with up to 4% Bi show the concentration of acceptor states increases rapidly with increasing Bi-content. The acceptor concentration is equal to that of closed Bi3 clusters, suggesting they are the source of deep acceptor states in GaAsBi.

description: We demonstrate that the Renyi-2 entropy provides a natural measure of information for any multimode Gaussian state of quantum harmonic systems, operationally linked to the phase-space Shannon sampling entropy of the Wigner distribution of the state. We prove that, in the Gaussian scenario, such an entropy satisfies the strong subadditivity inequality, a key requirement for quantum information theory. This allows us to define and analyze measures of Gaussian entanglement and more general quantum correlations based on such an entropy, which are shown to satisfy relevant properties such as monogamy.
