description: Proteins are primary effectors of drug action; hence it is essential to study how drugs can affect protein expression, and activity (1). In cancer research, it is common to study the effects of anticancer drugs on proteins and pharmacoproteomics plays an important role in determining the effects of anti-cancer drugs on protein expression. More so, the effect of drugs on protein activity can be studied using enzymatic assays. Previous research found doxorubicin to inhibit both CYP1A2 and CYP3A4 activity (2). However, another research showed that doxorubicin induces CYP1A2 activity (3). These differences may be due to variance in species. On the other hand, paclitaxel was found to be a potent inducer of CYP3A in rats (4). Based on these findings one can speculate that doxorubicin may inhibit CYP3A4, and induce CYP1A2, whereas, paclitaxel may induce CYP3A4 homolog in mice. Male and Female H: NU nude mice (n=30 including untreated mice) were treated peritoneally for 24 hours with 20mg/kg paclitaxel, paclitaxel solvent (10% DMSO, 10% Cremophor oil, and 80% saline), and intravenously with 10mg/kg doxorubicin, and doxorubicin solvent (saline) by Home Office licensed staff at the Institute of Cancer Therapeutics, University of Bradford. The influence of doxorubicin, and paclitaxel administration on the activities of CYP1A2 and CYP3A present in mouse liver microsomes was analysed using vivid assays. Given that vivid assays are designed for human CYP1A2 and CYP3A4, the ability to use vivid assays for mouse enzymes was novel. Vivid assay revealed that female mice had generally higher activity than male mice. The exact subtype of CYP affected could not be determined due to the lack of specificity of the vivid substrates. However, the protein activity observed was evidently due to the presence of CYP450 enzymes in the samples. There was a significant difference between treated (0.01/min ± 0.00 – 0.03/min ± 0.01) and untreated (0/min ± 0.00) female samples (p ≥ 0.05) analysed with CYP1A2 vivid substrate (EOMCC). However, treated (0.01/min ± 0.00) and untreated (0.01/min ± 0.01) male samples showed no significant difference. The results were similar after analysis with CYP3A4 vivid substrate (BOMCC). The values represent mean ± SEM, and significance was tested using ANOVA analysis.
In conclusion, it is possible to use mouse models for vivid assays although some improvements may be necessary. Moreover, CYP450s seemed to have been induced by doxorubicin and paclitaxel in female samples, due to higher activity rates in treated samples when compared with untreated samples.

description: Collections as Data (CAD) Personas represent an initial set of high level role types associated with collections as data activity. While distinctions are fuzzy in the context of disciplinary and professional praxis, roles represented by personas can generally be understood in alignment with data stewardship or use. On the whole, personas aim to surface needs, motivations, and goals in context. These representations are derived from Collections as Data project engagements and project team experience.

In Agile software development, a persona is used to help develop a broadly shared orientation to user experience. Gary Geisler has written, “Personas offer a way to summarize findings from user research and help determine user requirements and priorities. These documents help project teams develop a common understanding of a project’s intended audience and priorities. They also serve as a useful reference for design decisions throughout the development process.”

Fundamentals of Radar: It Depends on the Application - A Tutorial Introduction Slides
Creators: H Brian Sequeira
Publisher: name: IEEE
Year: 2018

MTT Webinar Slides
This tutorial approaches development of radar fundamentals from that sentiment by asking and answering the following questions: Under what conditions can we make application- independent statements about a radar system? What factors inject application specificity into radar design and how? To do this, I have developed the radar formalism slightly different from prior expositions of the subject, and applied the formulation to the ARS-11 air traffic control radar as an example. At several points, I reference aspects of automotive radar as an illustration of the kinds of considerations that occupy a radar engineer.
Advances in Linearization of Wideband (GaN) Power Amplifiers Slides
Creators: Allen Katz
Publisher: name: IEEE
Year: 2016

MTT Webinar Slides
This presentation discusses the state of the art in achieving wideband (> 1 GHz) linearization of power amplifiers. Multi-octave bandwidth linearization has been achieved at frequencies from L through millimeter-wave bands. Basic linearization concepts are reviewed. Emphasis is placed on the use of pre-distortion linearization and particularly on its application with amplifiers employing GaN FET power devices. The trades between using a single pre-distortion linearizer and multi-band linearizers are discussed. The effect of harmonics (both even and odd order distortion products) and their correction for applications that cover more than an octave are considered.
That which is between internal and external : a visual investigation
Creators: name: Reynolds, RM
Publisher: name: University Of Tasmania
Year: 2023

description: In my research I have focused on what it is that is between opposites. I have considered the edge of the human body (the skin) as that which is between the opposites of internal and external. The understanding of what is inside and what is outside our skin is considered by many to underlie our acknowledgment of all other opposites and definitions. As well as being interpreted as a site of separation the skin can be considered a site where inside and outside converge. Because of this duality, it is often referenced by artists who associate this aspect of the body's edge with a meeting place between internal and external including Eva Hesse, Anna Mendieta, Yayoi Kusama and Doris Salcedo, to whom I have given particular attention in the theoretical and practical aspects of my investigation. My studio research has aimed to explore the subtle, smooth, fragile visual transitions between suggested internal and external forces. In sculpture and installation works I have experimented with materials associated with skin, in particular those that come through the skin, such as salt and water. I have also considered the use of fabric in order to represent the transition between inside and outside. I have mixed edible flour with talcum powder to confuse the two realms of inside and outside. I have approached my research through process, allowing my intentions to have a connection with my processes of making; this often results in ephemeral works. These latter works have been documented during the research project. Several further ephemeral works will have been created for the examination submission and these reflect my investigations into this particular aspect of the sculptural process. The research project is a significant investigation of the potential of ephemeral sculpture to represent the transition between inside and outside.
Catalytic studies of low valent palladium \\(N\\)-heterocyclic carbene complexes
Creators: name: Riapanitra, A
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis describes the synthesis of low valent \\(N\\)-heterocyclic carbene palladium complexes. The aim of this project was to investigate the identity of \\(in\\) \\(situ\\) formed \\(N\\)-heterocyclic carbene palladium species under catalytically relevant reaction conditions from palladium(II) precatalysts. This aim was underpinned by the importance of neutral and cationic palladium(II) complexes widely used as precatalysts for carbon monoxide/ethene copolymerisation as well as various related C-C coupling reactions. The use of bulky chelating ligands is an important factor for catalytic performance in these reactions. Consequently, we focussed on a variety of arylsubstituted methylene bridged bis(N-heterocyclic carbene) palladium complexes. In order to achieve our aims, various attempts to synthesise complexes under reductive/basic conditions were undertaken, which led to the synthesis of several known precursors and novel complexes. Reaction of the dicationic Pd(II) complexes [{1,1'-di(aryl)-3,3'-methylenediimidazolin-2,2'-diylidene} palladium(II)bis(acetonitrile)] [PF\\(_6\\)]\\(_2\\) (aryl = 2,4,6-mesityl and 2,6-diisopropylphenyl) with sodium carbonate in methanol afforded novel dipalladium(I) hydride complexes [{bis(˜í¬¿-carbene)}\\(_2\\)Pd\\(_2\\)H][PF\\(_6\\)]. Steric influences led to major structural differences; Pd-Pd-H core (for 2,4,6-mesityl) and linear Pd-H-Pd core (for 2,6-diisopropylphenyl). The complexes were characterised by \\(^1\\)H, \\(^{13}\\)C, 2D and VT NMR spectroscopy (revealing differences in fluxional behaviour), mass spectroscopy, microanalysis and X-ray and neutron (2,4,6-mesityl only) crystallography. The metal oxidation states of both dipalladium hydride complexes have been shown to be Pd(I) by DFT calculations, but the precise nature of the Pd-Pd-H and Pd-H-Pd interactions remains to be confirmed. The synthesis of analogous complexes with less bulky phenyl and \\(tert\\)-butyl substituents were unsuccessful. The reactivity of these cationic dinuclear Pd(I) hydride complexes as catalysts were examined in carbon monoxide/ethene copolymerisation as well as various C-C coupling reactions (2,4,6-mesityl substituent only for the latter). Their poor performance indicated that the dipalladium(D hydride complexes were inefficient catalysts for carbon monoxide/ethep.e copolymerisation, which may suggest that a palladium methoxide species is the actual catalyst instead of palladium hydride species

description: Most differential equations found in chemical reaction networks (CRNs) have the form $dx/dt=f(x)= Sv(x)$, where $x$ lies in the nonnegative orthant, where $S$ is a real matrix (the stoichiometric matrix) and $v$ is a column vector consisting of real-valued functions having a special relationship to $S$. Our main interest will be in the Jacobian matrix, $f'(x)$, of $f(x)$, in particular in whether or not each entry $f'(x)_{ij}$ has the same sign for all $x$ in the orthant, i.e., the Jacobian respects a sign pattern. In other words species $x_j$ always acts on species $x_i$ in an inhibitory way or its action is always excitatory. In Helton, Klep, Gomez we gave necessary and sufficient conditions on the species-reaction graph naturally associated to $S$ which guarantee that the Jacobian of the associated CRN has a sign pattern. In this paper, given $S$ we give a construction which adds certain rows and columns to $S$, thereby producing a stoichiometric matrix $\widehat S$ corresponding to a new CRN with some added species and reactions. The Jacobian for this CRN based on $\hat S$ has a sign pattern. The equilibria for the $S$ and the $\hat S$ based CRN are in exact one to one correspondence with each equilibrium $e$ for the original CRN gotten from an equilibrium $\hat e$ for the new CRN by removing its added species. In our construction of a new CRN we are allowed to choose rate constants for the added reactions and if we choose them large enough the equilibrium $\hat e$ is locally asymptotically stable if and only if the equilibrium $e$ is locally asymptotically stable. Further properties of the construction are shown, such as those pertaining to conserved quantities and to how the deficiencies of the two CRNs compare.

Studies on the ATP phosphohydrolase activities of Escherichia coli
Creators: name: Davies, Peter L.
Publisher: name: University of British Columbia
Year: 2011

description: The adenosine triphosphate-hydrolysing activities of Escherichia coli NRC 482 were investigated. These activities could be accounted for by two enzymes, one of which was 5'-nucleotidase and the other was a Ca²⁺ -or Mg²⁺ -activated ATP phosphohydrolase (ATPase). The 5'-nucleotidase and the Ca²⁺ -or Mg²⁺ -activated ATPase could be readily distinguished on the basis of their properties and could be separated from each other by ion exchange chromatography. Both soluble and membrane-bound Ca²⁺ -or Mg²⁺ -activated ATPase activities were present in cell extracts. The membrane-bound ATPase, though firmly attached to the membrane, could be solubilized under conditions in which the membranes were depleted of divalent metal ions. This solubilized ATPase was identical to the ATPase found In the soluble fraction. The Ca²⁺-or Mg²⁺activated ATPase was partially purified after solubilization from E. coli membranes by gel filtration and ion exchange chromatography. The ATPase activity was shown to correspond to a single protein band after polyacrylamide gel electrophoresis. The enzyme had a molecular weight of 375,000. It was activated by divalent but not by monovalent cations. Optimal activity occured at pH 9.5 and at ion to substrate ratios of 2:5 and 2:3 with Mg²⁺ and Ca²⁺, respectively. ADP inhibited the ATPase reaction. The ATPase was stable at 22°- 2k° but was rapidly inactivated at 4°, Glycerol stabilized the enzyme at both temperatures. In these, and in other respects, the Ca²⁺ or Mg²⁺ -activated ATPase of E. coli resembled the ATPase activities of other bacterial strains, which in turn have a resemblance to the mitochondrial and chloroplast ATPases. To help establish the function of the Ca²⁺ -or Mg²⁺ -activated ATPase the levels of the enzyme were measured in E. coll grown under a variety of conditions. The level of the enzyme in the cell was not affected by the carbon source, phase of growth, aeration of the culture or the extent of catabolite repression, although these are conditions under which the efficiency of oxidative phosphorylation is known to vary in vivo. These findings can be reconciled with the current hypothesis regarding the function of the ATPase in E. coli.

description: The Chandra COSMOS Survey (C-COSMOS) is a large, 1.8 Ms, Chandra program, that covers the central contiguous ~0.92 deg^2 of the COSMOS field. C-COSMOS is the result of a complex tiling, with every position being observed in up to six overlapping pointings (four overlapping pointings in most of the central ~0.45 deg^2 area with the best exposure, and two overlapping pointings in most of the surrounding area, covering an additional ~0.47 deg^2). Therefore, the full exploitation of the C-COSMOS data requires a dedicated and accurate analysis focused on three main issues: 1) maximizing the sensitivity when the PSF changes strongly among different observations of the same source (from ~1 arcsec up to ~10 arcsec half power radius); 2) resolving close pairs; and 3) obtaining the best source localization and count rate. We present here our treatment of four key analysis items: source detection, localization, photometry, and survey sensitivity. Our final procedure consists of a two step procedure: (1) a wavelet detection algorithm, to find source candidates, (2) a maximum likelihood Point Spread Function fitting algorithm to evaluate the source count rates and the probability that each source candidate is a fluctuation of the background. We discuss the main characteristics of this procedure, that was the result of detailed comparisons between different detection algorithms and photometry tools, calibrated with extensive and dedicated simulations.

Evidence for Merger-Driven Activity in the Clustering of High Redshift Quasars

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Recently, a very large clustering length has been measured for quasars at a redshift of z~4. In combination with the observed quasar luminosity function we assess the implications of this clustering for the relationship between quasar luminosity and dark matter halo mass. Our analysis allows for non-linearity and finite scatter in the relation between quasar luminosity and halo mass, as well as a luminosity dependent quasar lifetime. The additional novel ingredient in our modelling is the allowance for an excess in the observed bias over the underlying halo bias owing to the merger driven nature of quasar activity. We find that the observations of clustering and luminosity function can be explained only if both of the following conditions hold: (i) The luminosity to halo mass ratio increases with halo mass; (ii) The observed clustering amplitude is in excess of that expected solely from halo bias. The latter result is statistically significant at the 99% level. Taken together, the observations provide compelling evidence for merger driven quasar activity, with a black-hole growth that is limited by feedback. In difference from previous analyses, we show that there could be scatter in the luminosity halo mass relation of up to 1 dex, and that quasar clustering can not be used to estimate the quasar lifetime.

The main problem is to compute the $k$-th moment of the 1-norm, with $k\to\infty$, and we present a number of general comments in this direction.

description: We investigate pairing symmetry in the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) vortex state and vortex lattice, and explain the electronic structure in these states in terms of pairing symmetry. We show analytically that at the intersection point of FFLO nodal plane and vortex line, only even frequency pairing is present if the Zeeman splitting is negligibly small. With increasing Zeeman splitting, odd frequency pairing emerges there. This makes it possible to interpret the gap structure of the density of states at the intersection point as a manifestation of the even frequency pairing. In the vortex lattice, we find that only odd frequency pairing is present at the core centers, while at the midpoint of the vortex lines, only even frequency pairing exists. Thus, the odd and even frequency pairings also form the lattice in the vortex lattice state.

description: Accretion and star formation (SF) rates in low redshift SDSS type-II active galactic nuclei (AGN) are critically evaluated. Comparison with photoionization models indicates that bolometric luminosity (Lbol) estimates based on L(oiii 5007A) severely underestimate Lbol in low ionization sources such as LINERs. An alternative method based on L(hb) is less sensitive to ionization level and a novel method, based on a combination of L(oiii 5007A) and L(oi 6300A), is erhaps the best. Using this method I show that low ionization AGN are accreting faster than assumed until now. Significant related other findings are: 1. Any type-II AGN property related to the black hole (BH) mass is more reliably obtained by removing blue galaxies from the sample. 2. Seyfert 2s and LINER 2s form a continuous sequence of L/Ledd with no indication for a change in accretion mechanism, or mode of mass supply. There are very few, if any, LINERs in all type-I samples which results in a much arrower L/Ledd distribution compared with type-II samples. 3. There is a strong correlation between SF luminosity, Lsf, and Lbol over more than five orders of magnitude in luminosity. This leads to a simple relationship between bulge and BH growth rates, g(bulge)/g(BH) propto Lbol^(-0.2), where g(bulge)/g(BH) = 115 for Lbol=10^42 erg/sec. Seyfert 2s and LINER 2s follow the same Lsf-Lbol correlation for all sources with a stellar age indicator, D4000, smaller than 1.8. This suggests that a similar fraction of SF gas finds its way to the center in all AGN. 4. Lbol, Lsf, L/Ledd and the specific SF rate follow D4000 in a similar way.

MTT Webinar Slides
During the past 50 years, phased-arrays have being largely developed for the defense sector.  Today, due to the increased demand for data, there is a need for base-station and mobile-user phased-arrays which can provide high-capacity data services through directional links. Both digital-beamforming at the element level (sub-6 GHz) and hybrid (i.e. analog/digital) beamforming for the mm-waves bands are being developed for 5G systems.  These commercial investments are leading to dramatic changes in phased-arrays: High EIRP, high-performance systems at 12, 14 GHz and 28 GHz (SATCOM), X/Ku-band (Radars), 24-30 GHz, 37-42 GHz and even 60 GHz (all for 5G), and with multiple beams, are now available at low-cost. The single most important aspect of these arrays is their use of advanced silicon technologies and planar antennas for dramatically lowering the development and unit cost. The talk will summarize the work in this area, and present a roadmap for the future.

description: In the present paper, a performance analysis of an 18 levels IMS system building, built in Santiago de Cuba city, which is classified as very high seismic hazard level for the new Cuban code, is carried out using the static nonlinear analysis method, known as the pushover analysis in the specialized literature. A retrospective of this method and their basic objectives are also given, and his use in Cuba as well. To perform the analysis, a characterization of their components, material used in the time of construction of the building, loads analysis, including the prestressed load was done. To obtain the structure´s response and his corresponding performance level, various artificia earthquakes compatibles with the seismicity of the region, according with the seismic demand levels specified by the Cuban code, were determined and included in the analysis, even the El Centro earthquake, which is recognized as a transcendental earthquake by specialists worldwide.
The potential formations of plastic hinges were defined according to the building´s characteristics, which their occurrence was corroborate according with the structure´s
results. Geometric model was obtain using SAP2000 v16 software, and using the program´s capabilities, different features of the structure were determined, including,
dynamic response, capacity curve, hinge formation mechanism, story drifts, and maximum building´s drift, according to different levels of demand. Remarkable results of the performance objectives in the analyzed structure were obtained for each earthquake, as follows: for the earthquakes compatible with the seismicity of the zone, the
classification was Fully Operational for the Occasional event, and for the events Rare, and Very Rare the classification was Operational, fulfilling the objectives established according to the importance of the building.

description: We characterize pregeometries in terms of their flats - giving necessary and sufficient conditions for a collection of sets to be the flats of a pregeometry. We begin a systematic study of automorphisms of pregeometries; arguing geometrically, we obtain the (known) factorization of a pregeometry into component pregeometries, and express the automorphism group of the pregeometry in terms of the automorphism groups of its components. We use automorphisms of pregeometries and their characterization above by flats in the following three ways: 1. All erections of any pregeometry are constructed and their automorphism group determined. 2. We indicate a process for obtaining all pregeometries on a set from the geometries on smaller sets and their automorphism groups. 3. We begin the study of the transitivity of the automorphism group of a pregeometry on the flats and the elements of the pregeometry.

description: We present a spectroscopic library of late spectral type stellar templates in the near-IR range 2.15-2.42microns, at R=5300-5900 resolution, oriented to support stellar kinematics studies in external galaxies, such as the direct determination of the masses of supermassive black-holes in nearby active (or non-active) galaxies. The combination of high spectral resolution and state-of-the-art instrumentation available in 8-m class telescopes has made the analysis of circumnuclear stellar kinematics using the near-IR CO band heads one of the most used techniques for such studies, and this library aims to provide the supporting datasets required by the higher spectral resolution and larger spectral coverage currently achieved with modern near-IR spectrographs. Examples of the application for kinematical analysis are given for data obtained with two Gemini instruments, but the templates can be easily adjusted for use with other near-IR spectrographs at similar or lower resolution. The example datasets are also used to revisit the "template mismatch" effect and the dependence of the velocity dispersion values obtained from the fitting process with the characteristics of the stellar templates. The library is available in electronic form from the Gemini web pages (link above).

John Shaw Neilson : the collected verse : a critical edition
Creators: name: Roberts, MD
Publisher: name: University Of Tasmania
Year: 2023

description: The thesis examines approximately 491 items of correspondence from the author to various recipients and shows that published biographies and biographical comments are ill-judged and misleading and cloud criticism of the verse. Neilson's method of composition, the use of amanuenses, and the use of the exercise books in which drafts of most of his work occur are discussed, and the influence of editors on the poet and the texts is examined. The edition includes all Neilson's verse, published and unpublished. It aims to be textually inclusive and to show both the process of composition and the text as a historical product. A text is regarded as a different version if alterations in wording are made by the author, or at his behest, or are accepted by him in copy authorised by him and which he has seen or heard, unless these are part of the original impulse of composition. A distinction is made for practical purposes between discrete versions, which involve a significant shift in meaning or emphasis, and theoretic versions, which do not. Neilson's texts have been described as a 'bibliographic nightmare' and as a 'well-nigh insoluble textual problem'. The thesis clarifies the problems and demonstrates that these are capable of resolution, and does this in a manner which will provide a sound basis for informed criticism of the verse.
Solitons as a signature of the modulation instability in the discrete nonlinear Schrodinger equation

Subjects: subject: Pattern Formation and Solitons (nlin.PS)

description: The effect of the modulation instability on the propagation of solitary waves along one-dimensional discrete nonlinear Schrödinger equation with cubic nonlinearity is revisited. A self-contained quasicontinuum approximation is developed to derive closed-form expressions for small-amplitude solitary waves. The notion that the existence of nonlinear solitary waves is a signature of the modulation instability is used to analytically study instability effects on solitons during propagation. In particular, we concern with instability effects in the dark region, where other analytical methods as the standard modulation analysis of planewaves do not provide any information on solitons. The region of high-velocity solitons is studied anew showing that solitons are less prone to intabilities in this region. An analytical upper boundary for the self-defocusing instability is defined.

Multidimensional phase space
Creators: name: Roberts, Martin
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis investigates the dimensional continuation of the standard 4-dimensional relativistic phase space to higher dimensions where all of the higher dimensions, beyond the usual four, are considered purely as flat spatial dimensions. Using standard approaches we are able to obtain simple closed expressions for the two- and three-body cases. We then take an alternative approach by recognizing an intimate connection between phase space and the 'sunset' diagram in co-ordinate space. This allows us to develop a kind of threshold expansion series for the phase space for an arbitrary number of massive particles in an arbitrary number of dimensions, in terms of the hypergeometric function. The beauty of this method is that the series terminates for odd dimensions, and easily describes the leading terms for even dimensions. We then develop a method for calculating phase space that is complementary to the Almgren recurrence relations. That is, it establishes relations between N‚ÄövÑvÆparticle phase space pN, in D‚ÄövÑvÆdimensions with N‚ÄövÑvÆparticle phase space in lower dimensions. This is done through a novel approach of considering phase space in higher dimensions where one or more of the (spatial) coordinates of space-time are confined to a torus or sphere of radius R and the limit as R ‚Äövúv¿ ‚Äöv†vª is taken. Summing over all the associated discrete modes leads to a mass integral, and hence the the resulting phase space is expressible as a set of mass integrals of pN in a dimension lower than D. Finally, we review some work done by Davydychev et al., which establishes an intimate connection between the integral associated with the one loop N‚ÄövÑvÆpoint Feynman diagram (the 'sun' diagram) and geometric aspects of its 'dual diagram' - an N‚ÄövÑvÆdimensional simplex (hyper-tetrahedron). This is of particular interest because the phase space integral is also closely associated with an N‚ÄövÑvÆdimensional simplex in Euclidean space. Therefore, by looking at the N‚ÄövÑvÆpoint single loop diagram and the N‚ÄövÑvÆloop two-point diagrams, we suggest that the geometry of the Feynman diagram itself contains valuable information that allows us to deduce a deeper structure to the field theory expressions. That is, inasmuch as the Feynman diagrams are a geometric interpretation of field theory interactions, this thesis intimates a geometric interpretation of the Feynman diagrams, themselves. This in turn, suggests that it may be possible to find a geometric interpretation, to a level deeper than ever before, of quantum field theory.

Recovering Signals from Lowpass Data

subject: FOS: Computer and information sciences

description: The problem of recovering a signal from its low frequency components occurs often in practical applications due to the lowpass behavior of many physical systems. Here we study in detail conditions under which a signal can be determined from its low-frequency content. We focus on signals in shift-invariant spaces generated by multiple generators. For these signals, we derive necessary conditions on the cutoff frequency of the lowpass filter as well as necessary and sufficient conditions on the generators such that signal recovery is possible. When the lowpass content is not sufficient to determine the signal, we propose appropriate pre-processing that can improve the reconstruction ability. In particular, we show that modulating the signal with one or more mixing functions prior to lowpass filtering, can ensure the recovery of the signal in many cases, and reduces the necessary bandwidth of the filter.

"Glassy" Relaxation in Catalytic Reaction Networks

description: Relaxation dynamics in reversible catalytic reaction networks is studied, revealing two salient behaviors that are reminiscent of glassy behavior: slow relaxation with log(time) dependence of the correlation function, and emergence of a few plateaus in the relaxation. The former is explained by the eigenvalue distribution of a Jacobian matrix around the equilibrium state that follows the distribution of kinetic coefficients of reactions. The latter is associated with kinetic constraints, rather than metastable states, and is due to the deficiency of catalysts for chemicals in excess and negative correlation between the two chemical species. Examples are given, and generality is discussed.
5G Enabling Technologies - MIMO, Multiuser MIMO, and Massive MIMO Slides
Creators: Abbas Omar
Publisher: name: IEEE
Year: 2017

MTT Webinar Slides
In this webinar, the fundamentals underlying the MIMO concept are explained. It will be shown how multiple reflections in indoor and urban environments can be effectively used to create additional independent channels that can serve the purposes of diversity and/or spatial multiplexing. Extending this concept for a base station to serve multiple users gives rise to Multiuser MIMO, in which both the number of served users and that of the array elements are very moderate. Massive MIMO on the other hand uses large antenna arrays to produce very narrow multiple beams that are capable of simultaneously establishing independent channels between the base station and a number of mobile or stationary users. The usually used deterministic and stochastic models for representing mobile wireless channels (linear time-varying systems) are explained emphasizing the massive-MIMO aspects. Sample massive-MIMO systems that have been recently developed are presented.
