description: Nowadays, innovation and application of new abbreviations is highly and rapidly represented on a large scale. The current study introduces various shortening processes such as clipping, abbreviation, backformation, acronym and blending and then, assesses them in web chats and determines their level of application. Based on different conducted researches, Persian internet users apply different shortening methods when they are chatting online, for instance using the shortened names of cities and countries, stereotypes, emoticons, shortened sentences, English abbreviations, numbers and also shortening the shortened vocabularies. Using abbreviations is the most common method of all these seven, and acronym process has the most productivity of all. Owing to the fact that if word-formation process is active in a language, borrowing will happen rarely; therefore, each language needs to take advantage of shortening processes especially acronyms.

description: Data-driven design is making headway into a number of application areas, including protein, small-molecule, and materials engineering. The design goal is to construct an object with desired properties, such as a protein that binds to a therapeutic target, or a superconducting material with a higher critical temperature than previously observed. To that end, costly experimental measurements are being replaced with calls to high-capacity regression models trained on labeled data, which can be leveraged in an in silico search for design candidates. However, the design goal necessitates moving into regions of the design space beyond where such models were trained. Therefore, one can ask: should the regression model be altered as the design algorithm explores the design space, in the absence of new data? Herein, we answer this question in the affirmative. In particular, we (i) formalize the data-driven design problem as a non-zero-sum game, (ii) develop a principled strategy for retraining the regression model as the design algorithm proceeds---what we refer to as autofocusing, and (iii) demonstrate the promise of autofocusing empirically.

description: We introduce a semi-parametric model for the primary mass distribution of binary black holes (BBHs) observed with gravitational waves (GWs) that applies a cubic-spline perturbation to a power law. We apply this model to the 46 BBHs included in the second gravitational wave transient catalog (GWTC-2). The spline perturbation model recovers a consistent primary mass distribution with previous results, corroborating the existence of a peak at $35\,M_\odot$ ($>97\%$ credibility) found with the \textsc{Powerlaw+Peak} model. The peak could be the result pulsational pair-instability supernovae (PPISNe). The spline perturbation model finds potential signs of additional features in the primary mass distribution at lower masses similar to those previously reported by Tiwari and Fairhurst (2021). However, with fluctuations due to small number statistics, the simpler \textsc{Powerlaw+Peak} and \textsc{BrokenPowerlaw} models are both still perfectly consistent with observations. Our semi-parametric approach serves as a way to bridge the gap between parametric and non-parametric models to more accurately measure the BBH mass distribution. With larger catalogs we will be able to use this model to resolve possible additional features that could be used to perform cosmological measurements, and will build on our understanding of BBH formation, stellar evolution and nuclear astrophysics.

description: We describe the impact of physics education research-based pedagogical techniques in flipped and active-engagement non-flipped courses on student performance on validated conceptual surveys. We compare student performance in courses which make significant use of evidence-based active engagement (EBAE) strategies with courses that primarily use lecture-based (LB) instruction. All courses had large enrollment and often had 100-200 students. The analysis of data for validated conceptual surveys presented here includes data from large numbers of students from two-semester sequences of introductory algebra-based and calculus-based introductory physics courses. The conceptual surveys used to assess student learning in the first and second semester courses were the Force Concept Inventory and the Conceptual Survey of Electricity and Magnetism, respectively. In the research discussed here, the performance of students in EBAE courses at a particular level is compared with LB courses in two situations: (I) the same instructor taught two courses, one of which was a flipped course involving EBAE methods and the other an LB course, while the homework, recitations and final exams were kept the same, (II) student performance in all of the EBAE courses taught by different instructors were averaged and compared with LB courses of the same type also averaged over different instructors. In all cases, we find that students in courses which make significant use of active-engagement strategies, on average, outperformed students in courses using primarily lecture-based instruction of the same type on conceptual surveys even though there was no statistically significant difference on the pretest before instruction. We also discuss correlation between the performance on the validated conceptual surveys and the final exam, which typically placed a heavy weight on quantitative problem solving.

description: The behavior of many magnetic and dielectric solids, and the more contemporary magnetic super-lattices, is governed by dipolar interactions. They are anisotropic and long-ranged, having varied consequences ranging from ground states with complicated magnetic order to the presence of glassy dynamics characterised by a plethora of relaxation times.These systems are well-captured by the dipolar Ising model (DIM) with nearest-neighbor exchange interactions (J) and long-range dipolar interactions (D). Depending on the relative interaction strength Γ =J/D, there are four phases of distinct magnetic order and symmetry. Using Monte Carlo simulations, we perform deep quenches to study domain growth or coarsening in the d= 3 DIM. This important non-equilibrium phenomenon has not been addressed as dipolar interactions are notoriously difficult to handle theoretically. Our study reveals that, in spite of the anisotropy in interactions and diversity in ground state configurations, we observe universality in the ordering dynamics of all phases.

description: We consider Gibbs distributions, which are families of probability distributions over a discrete space $Ω$ with probability mass function of the form $μ^Ω_β(ω) \propto e^{βH(ω)}$ for $β$ in an interval $[β_{\min}, β_{\max}]$ and $H( ω) \in \{0 \} \cup [1, n]$. The partition function is the normalization factor $Z(β)=\sum_{ω\inΩ}e^{βH(ω)}$.
 Two important parameters of these distributions are the log partition ratio $q = \log \tfrac{Z(β_{\max})}{Z(β_{\min})}$ and the counts $c_x = |H^{-1}(x)|$. These are correlated with system parameters in a number of physical applications and sampling algorithms.
 Our first main result is to estimate the counts $c_x$ using roughly $\tilde O( \frac{q}{\varepsilon^2})$ samples for general Gibbs distributions and $\tilde O( \frac{n^2}{\varepsilon^2} )$ samples for integer-valued distributions (ignoring some second-order terms and parameters), and we show this is optimal up to logarithmic factors. We illustrate with improved algorithms for counting connected subgraphs, independent sets, and perfect matchings.
 As a key subroutine, we also develop algorithms to compute the partition function $Z$ using $\tilde O(\frac{q}{\varepsilon^2})$ samples for general Gibbs distributions and using $\tilde O(\frac{n^2}{\varepsilon^2})$ samples for integer-valued distributions.

description: We consider a hybrid spatial communication system in which mobile nodes can connect to static sinks in a bounded number of intermediate relaying hops. We describe the distribution of the connection intervals of a typical mobile node, i.e., the intervals of uninterrupted connection to the family of sinks. This is achieved in the limit of many hops, sparse sinks and growing time horizons. We identify three regimes illustrating that the limiting distribution depends sensitively on the scaling of the time horizon.

description: This thesis decribes the choice, the construction, the operation, and the testing of a ³He melting curve thermometer. The melting curve thermometer satisfies the need of this particular laboratory for a convenient standard thermometer in the temperature range of 6 mK to 600 mK. Over most of its operating range, the resolution of the temperature measured with the ³He melting curve thermometer is 0.03%, however, the accuracy is only 0.3%. The construction of a precision low temperature strain gauge is described. Also a ratio transformer capacitance bridge which has a resolution of 1 ppm is described.

description: A novel Bethe ansatz scheme is proposed to investigate the exact physical properties of an integrable anisotropic quantum spin chain with competing interactions among the nearest, next nearest neighbor and chiral three spin couplings, where the boundary condition is the twisted one. The eigenvalue of the transfer matrix is characterized by its zero roots instead of the traditional Bethe roots. Based on the exact solution, the conserved momentum and charge operators of this U(1)-symmetry broken system are obtained. The ground state energy and density of rapidities are calculated. It is found that there exist three kinds of elementary excitations and the corresponding dispersion relations are obtained, which gives a different picture from that with periodic boundary condition.

description: Consider a simple random walk on $\mathbb{Z}$ with a random coloring of $\mathbb{Z}$. Look at the sequence of the first $N$ steps taken in the random walk, together with the colors of the visited locations. We call this the record. From the record one can deduce the coloring of of the interval in $\mathbb{Z}$ that was visited, which is of size approximately $\sqrt{N}$. This is called scenery reconstruction. Now suppose that an adversary may change $δN$ entries in the record that was obtained. What can be deduced from the record about the scenery now? In this paper we show that it is likely that we can still reconstruct a large part of the scenery.
 More precisely, we show that for any $θ<0.5,p>0,ε>0$, there are $N_{0}$ and $δ_{0}$ such that if $N>N_{0}$ and $δ<δ_{0}$ then with probability $>1-p$, the walk is such that we can reconstruct the coloring of $>N^θ$ integers, up to a number of possible reconstructions that is less than $2^{εs}$, where $s$ is the number of integers whose color we reconstruct.

description: We consider Bose-Einstein condensation of massive electrically charged scalars in a uniform background of charged fermions. We focus on the case when the scalar condensate screens the background charge, while the net charge of the system resides on its boundary surface. A distinctive signature of this substance is that the photon acquires a Lorentz-violating mass in the bulk of the condensate. Due to this mass, the transverse and longitudinal gauge modes propagate with different group velocities. We give qualitative arguments that at high enough densities and low temperatures a charged system of electrons and helium-4 nuclei, if held together by laboratory devices or by force of gravity, can form such a substance. We briefly discuss possible manifestations of the charged condensate in compact astrophysical objects.

Atomic capture of negative muons in oxides
Creators: name: Stanislaus, Thanthirimudalige Don Shirvel
Publisher: name: University of British Columbia
Year: 2010

description: Using the lifetime technique, atomic capture ratios of negative muons have been measured in 41 oxides. The experimental method was to detect the decay electrons and to use the unique lifetime signature to identify the element which captured the muon. Muons were produced via the backward decay of pions which were provided by the M20 channel at TRIUMF. The experimental set-up and electronic logic were tested against the positive muon lifetime which was measured to be 2197.7 ± 2.6 ns, in good agreement with the present world average of 2197.138 ± 0.065 ns. The results, though somewhat different from the earlier TRIUMF findings, are consistent with the mesic x-ray measurements. We have also carried out new measurements for MnO, Fe₃O₄, Coo, NiO, NbO, MoO₂, SnO, PrO₂, HgO and Pb₃O₄. It has been noticed that the atomic capture ratios have a linear dependence on the density, whereas the Z-dependence is periodic. Using our results and data from the literature, we have been able to obtain an empirical formula for the atomic capture ratios in oxides, chlorides and fluorides. Our results for oxides, also show evidence for the existence of chemical and/or solid state effects in the atomic capture process. The lifetimes of negative muons bound in heavy nuclei were also measured during this experiment. Our results are in good agreement with the earlier measurements carried out at TRIUMF.

description: We study the finite-temperature behavior of the A^2 condensate in the Landau gauge of SU(2) Yang--Mills theory on the lattice in a wide range of temperatures. The asymmetry between the electric (temporal) and magnetic (spatial) components of this unconventional dimension-2 condensate is a convenient ultraviolet-finite quantity which possesses, as we demonstrate, unexpected properties. The low-temperature behavior of the condensate asymmetry suggests that the mass of the lowest thermal excitation in the condensate is unexpectedly low, about 200 MeV, which is much smaller than the glueball mass. The asymmetry is peaking at the phase transition, becoming a monotonically decreasing function in the deconfinement phase. A symmetric point is reached in the deconfinement phase at a temperature approximately equal twice the critical temperature. The behavior of the electric-magnetic asymmetry of the condensate separates the phase diagram of Yang-Mills theory into three regions. We suggest that these regions are associated with the condensed, liquid and gaseous states of the confining gluonic objects, the Abelian monopoles.

OuroborosBEM: A fast multi-GPU microscopic Monte Carlo simulation for gaseous detectors and charged particle dynamics

description: The design of gaseous detectors for accelerator, particle and nuclear physics requires simulations relying on multi-physics aspects. In fact, these simulations deal with the dynamics of a large number of charged particles interacting in a gaseous medium immersed in the electric field generated by a more or less complex assembly of electrodes and dielectric materials. We report here on a homemade software, called OUROBOROSBEM, able to tackle the different features involved in such simulations. After solving the electrostatic problem for which a solver based on the boundary element method (BEM) has been implemented, particles are tracked and will microscopically interact with the gas medium. Dynamical effects have been included such as the electron-ion recombination process, the charging-up of the dielectric materials and other space charge effects that might alter the detector performances. These were made possible thanks to the nVidia CUDA language specifically optimised to run on Graphical Processor Units (GPUs) to minimize the computing times. Comparisons of the results obtained for parallel plate avalanche counters and GEM detectors to literature data on swarm parameters fully validate the performances of OUROBOROSBEM. Moreover, we were able to precisely reproduce the measured gains of single and double GEM detectors as a function of the applied voltage.
title: The probation service and the governance of the offender : discourse, power and politics in the probation service in England and Wales.
Creators: name: Oldfield, Mark
Publisher: name: University of Kent
Year: 2001

description: The study is informed by Foucault's concept of 'governmentality' - the ways in which agencies and institutions attempt to shape the conduct of individuals in modem democracies. The study links this conception of governance to two major trains of political thought which, it is argued, characterise the ways in which twentieth century society in the United Kingdom has been organised. Given that modem society translates its political problems into 'tecimical' solutions through the use of various agencies such as probation, it is argued that the discourse of probation will reflect certain tenets of the salient political rationality at a particular time. The first such political rationality is identified as 'welfarism', an approach to government through a complex apparatus of expert agencies and practitioners charged with addressing the conduct of citizens across a wide ranging terrain of social and economic life. In contrast to this, a neo-liberal rationality, predicated upon individualism is depicted as having become increasingly influential since the late 1 970s, restructuring practice away from welfarist approaches that sought to provide services aimed at the creation of better citizens. The thesis of this study holds that the shift away from the welfarist rationality of governance will be reflected within the organisation and practice of the present day probation service. To determine the extent of this shift, probation discourse is analysed in tenns of its resonance with the tenets of welfarism and neo-liberalism. The study addresses organisational and epistemological discourse over the twentieth century using the texts and documents through which probation was debated, discussed and practised in order to map out the contours of welfarism and neo-liberalism. To determine the extent of contemporary change, a sample of presentence reports is analysed in terms of their correspondence with the two political rationalities. It is concluded that, whilst organisationally there has been a clear shift toward neo-liberalismn, probation practice still evidences certain approaches that are informed by a more welfarist discourse, suggesting a certain 'hybridity' of practice.

description: Following the discovery of a new family of kagomé prototypical materials with structure AV$_3$Sb$_5$ (A = K, Rb, Cs), there has been heightened interest in studying the correlation-driven electronic phenomena in these kagomé lattice systems. The study of these materials has gone beyond magneto-transport measurements to reveal exciting features such as Dirac bands, anomalous Hall effect, bulk superconductivity with $T_c$ $\sim$ 0.9 K-2.5 K, and the observation of charge density wave instabilities, suggesting an intertwining of topological physics and new quantum orders. Moreover, very recent works on numerous types of experiments have appeared further examining the unconventional superconductivity and the exotic electronic states found within these kagomé materials. Theories on the strong interactions that play a role in these systems have been proposed to shed light on the nature of these topological charge density waves. In this brief review, we summarize these recent experimental findings and theoretical proposals, and envision the materials as new platforms to study the interplay between topological physics and strongly-correlated electronic systems.

description: Pollen cryopreservation in Bottle gourd for breeding and conservation Laxmi Mastiholi*, Anilkumar G S and Rajasekharan P E Division of Flower and Medicinal Crops, ICAR-IIHR, Bengaluru Abstract Bottle gourd (Lagenaria siceraria (Molina) Standl.) also known as Calabash, is one of the most important cucurbitaceous vegetable in India with more genetic diversity. Which can be used as vegetable, water receptacle, musical instrument or as medicinal plants. As monoecious nature of bottle gourd, male flower grows on long peduncle and female flower on short peduncle however it has an ovary in the shape of the fruit. Anthesis and dehiscence time is moderately influenced by humidity and temperature conditions and also there is seasonal variation in photoperiod insensitive and sensitive genotype. So to avoid this seasonal variation in breeding programme, we have done pollen cryopreservation. At the time of anthesis (4:30 to 7 p.m.) pollen were collected from field and pre storage germination assessment was carried by hanging drop technique using modified Brewbaker and Kwack media containing different concentration of sucrose. After 1 hour desiccation in zeolite beads the pollen were packed in butter paper covers enclosed in sealed aluminium pouches which were rapidly plunged into the cryobiological system containing liquid nitrogen. After cryopreservation the germination test was carried out to know the percentage of germination of cryopreserved pollen. The fresh pollen recorded germination percentage of 97.20 % and it was 96.50 % after one week of cryopreservation in 15% sucrose. The results indicate that, there is no significant decline in viability of cryopreserved pollen. The cryopreservation of bottle gourd pollen helps for production of the cross combination genotypes (Photosensitive and insensitive) with year round supplementary pollination. Cryopreservation of pollen offers a simple and effective method of long-term pollen storage. Pollen stored in liquid nitrogen (LN) for many years without loss of its essential capabilities to pollinate, fertilize, and set normal fruit and seed when used in plant breeding, for controlled pollinations, or for the conservation of plant genetic resources.

urn:lsid:zoobank.org:act: 51FDC5C3-01AA-47F6-B678-F67E2C360F4A
Fig. 7; Table 2
Diagnosis
Species of Temnocheilus with thickly pachyconic, subevolute conch (ww/dm ~0.80; uw/dm ~0.35); whorl profile strongly depressed, rounded-trapezoidal (ww/wh ~ 2.05), venter broadly rounded, ventrolateral shoulder angular with large, elongated longitudinal nodes (about 10 per whorl). Whorls weakly embracing. Shell surface almost smooth.
Etymology
Named after Martina Aubrechtová, in honour of her studies on Palaeozoic nautiloids.
Material examined
Holotype MOROCCO • Anti-Atlas, region south-west of Rissani; basal Mougoui Ayoun Formation; Karaoui Coll.; illustrated in Fig. 7; PIMUZ 39511.
Description
Holotype PIMUZ 93511 is a slightly deformed but otherwise rather well-preserved specimen with a conch diameter of 54 mm (Fig. 7). The last quarter of the last preserved whorl belongs to the body chamber. The conch is thickly pachyconic to cadiconic and subevolute with a high coiling rate (WER =2.04–2.21). The whorl profile is broadly trapezoidal (ww/wh 1.88 to 2.14) with a very broadly and continuously rounded venter; the ventrolateral shoulder is narrowly rounded. The nodes are about twice as long as they are wide and their spacing is equal to their length. There are ten such nodes on the last whorl, giving the ventrolateral shoulder a conspicuous coronate appearance.
Remarks
Temnocheilus aubrechtovae sp. nov. differs from the other Early Carboniferous species of the genus in the shape of the venter, which is either nearly flat (e.g., T. coronatus, T. imazighenorum sp. nov.) or slightly concave (e.g., T. ventroconcavum). Temnocheilus coronatiformae has a similar conch shape but differs from T. aubrechtovae in the much smaller and more numerous ventrolateral nodes (about 15 per volution).

It is shown that the number of such states is described by the fractal Weyl law and their Husimi distributions closely follow the strange repeller set formed by classical orbits nonescaping in future times. For large matrices the distribution of escape rates converges to a fixed shape profile characterized by a spectral gap related to the classical escape rate.

description: General relativity predicts that the rotational momentum flux of matter twists the spacetime via a vector gravitomagnetic (frame-dragging) field, which remains undetected in cosmology. This vector field induces an additional gravitational lensing effect; at the same time, the momentum field sources the kinetic Sunyaev-Zel'dovich (kSZ) effect. The common origin of these two effects allows us to probe the gravitomagnetic signal via their cross-correlations. In this paper, we explore the possibility of detecting the gravitomagnetic field in $Λ$CDM by cross-correlating the weak-lensing convergence field with the CMB temperature map, which is imprinted with the kSZ signal. This approach allows us to extract the gravitomagnetic effect because the cross correlation between the standard Newtonian contribution to the weak-lensing convergence field, $κ_Φ$, and the kSZ effect is expected to vanish. We study the cross correlations with a suite of large-volume Newtonian $N$-body simulations and a small-volume, high-resolution, general-relativistic counterpart. We show that insufficient simulation resolution can introduce significant spurious correlations between $κ_Φ$ and kSZ. From the high-resolution simulation, we find that the cumulative signal-to-noise ratio (SNR) of the kSZ-gravitomagnetic convergence field can reach almost 15 (30) at $\ell\simeq5000$ ($10^4$) for the lensing source redshift $z_s=0.83$, if only cosmic variance is considered. We make forecast for next-generation lensing surveys such as Euclid and LSST, and CMB experiments such as Simons Observatory and CMB-S4, and find that, for $z_s=1.4$, the cumulative SNR can exceed 5 (9) at $\ell\simeq5000$ ($10^4$), indicating that the cosmological gravitomagnetic effect can be detected, if several foreground contaminations can be removed.

description: Verhüllung ist Verheißung. Wie der bulgarisch-amerikanische Verpackungskünstler Christo schon so treffend sagte, spielt besonders bei Süßwaren die Verpackung eine besondere Rolle – ein erster und damit kaufentscheidender Eindruck für genussvolle Momente. Als Träger für Werbung sind sie meist optisch ansprechend und erfüllen gleichzeitig weitere wichtige Grundfunktionen. Doch dies hat seinen Preis: Im Jahr 2021 stieg die Verpackungsabfallmenge auf den bislang höchsten Stand von 19,7 Mio. t – ein trauriger Rekord. Leider stammt ein Großteil dieser Verpackungen aus der Lebensmittelindustrie. Obwohl das Verpackungsgesetz (VerpackG) in § 4 vorschreibt, Verpackungen nur so zu entwickeln, herzustellen und zu vertreiben, dass ihr Verpackungsvolumen und -masse auf ein Mindestmaß begrenzt sind, folgt nicht jeder Hersteller dieser Vorgabe. Grund genug sich auch im Rahmen der DLG-Verpackungsprüfung mit dieser Problematik auseinanderzusetzen. Daher wurde in einer Marktstudie an der Hochschule Anhalt untersucht, wie das Verhältnis der Verpackung zu Packgut von Süßwarenpackungen ausfällt.

description: Host-based threats such as Program Attack, Malware Implantation, and Advanced Persistent Threats (APT), are commonly adopted by modern attackers. Recent studies propose leveraging the rich contextual information in data provenance to detect threats in a host. Data provenance is a directed acyclic graph constructed from system audit data. Nodes in a provenance graph represent system entities (e.g., $processes$ and $files$) and edges represent system calls in the direction of information flow. However, previous studies, which extract features of the whole provenance graph, are not sensitive to the small number of threat-related entities and thus result in low performance when hunting stealthy threats.
 We present threaTrace, an anomaly-based detector that detects host-based threats at system entity level without prior knowledge of attack patterns. We tailor GraphSAGE, an inductive graph neural network, to learn every benign entity's role in a provenance graph. threaTrace is a real-time system, which is scalable of monitoring a long-term running host and capable of detecting host-based intrusion in their early phase. We evaluate threaTrace on three public datasets. The results show that threaTrace outperforms three state-of-the-art host intrusion detection systems.

description: In this paper, we consider the use of radio environment maps (REMs) in vehicular dynamic spectrum access (VDSA) for vehicle platooning applications. We propose an algorithm that dynamically allocates the frequency bands and transmission power in the so-called TV white spaces (TVWS) for intra-platoon messaging, intending to maximize the reliability of the communications, simultaneously keeping the interference to the primary system below the required threshold. The proposed solution is evaluated in simulations, with the results indicating a significant increase in communications reliability with VDSA.

description: Experimental determination of absolute surface energies remains a challenge. We propose a simple method based on two independent measurements on 3D and 2D equilibrium shapes completed by the analysis of the thermal fluctuation of an isolated step. Using then basic equations (Wulff' theorem, Gibbs-Thomson equation, thermodynamics fluctuation of an isolated step) allows us to extract the absolute surface free energy of a singular face. The so-proposed method can be applied when (i) all orientations exists on the equilibrium shape, (ii) the surface stress is isotropic. This procedure is applied to the case of Si(111) where we find a value between 0.59 Jm-2 and 0.83 Jm-2 at 1373 K.

description: We study time-dependent quantum transport in a correlated model system by means of time-propagation of the Kadanoff-Baym equations for the nonequilibrium many-body Green function. We consider an initially contacted equilibrium system of a correlated central region coupled to tight-binding leads. Subsequently a time-dependent bias is switched on after which we follow in detail the time-evolution of the system. Important features of the Kadanoff-Baym approach are 1) the possibility of studying the ultrafast dynamics of transients and other time-dependent regimes and 2) the inclusion of exchange and correlation effects in a conserving approximation scheme. We find that initial correlation and memory terms due to many-body interactions have a large effect on the transient currents. Furthermore the value of the steady state current is found to be strongly dependent on the approximation used to treat the electronic interactions.

description: We derive a closed-form false vacuum decay rate at one loop in the thin wall limit, where the true and false vacua are nearly degenerate. We obtain the bounce configuration in $D$ dimensions, together with the Euclidean action with a higher order correction, counter-terms and renormalization group running. We extract the functional determinant via the Gel'fand-Yaglom theorem for low and generic orbital multipoles. The negative and zero eigenvalues appear for low multipoles and the translational zeroes are removed. We compute the fluctuations for generic multipoles, multiply and regulate the orbital modes. We find an explicit finite renormalized decay rate in $D = 3, 4$ and give a closed-form expression for the finite functional determinant in any dimension.

(In)attualità e (a)temporalità del bunker L’architettura di Bernard Khoury a Beirut

description: Too often the architecture of the very well-known Lebanese architect Bernard Khoury is likened to bunker architecture, for the issues that move his talent as architect. The precision of the combat architecture’s mechanisms fascinated his fantasy and help him to imagine a new morphology for the buildings he designs according to context. This short essay argues that the use of war architecture as a metaphor in Bernard Khoury’s design concepts should be interpreted more as a radical criticism to the common notion of restoration than a formalist tool. In his approach, in fact, the meaning of restoration’s project doesn’t belong to the concept of “how it was, where it was” but deals with the burden of dreams and nightmares which citizens find in the scars of Beirut.
Statistics of coherent structures in turbulent fluid flow

Publisher: name: University of British Columbia
Year: 2010

description: This thesis compares power spectra produced from hot-film anemometery measurements in turbulent flow with those generated from the distribution of eddy sizes obtained from photographs of the same flow. The coherent structures were made visible by photographing the paths of aluminum tracers on the surface of a water filled towing tank. A parallel row of bars was used to generate the turbulent flow. Flow Reynold's numbers, based on bar spacing, of about 20,000 were studied. A simple analysis of the flow patterns photographed proved adequate to predict power spectra consistent with those measured using a hot-film anemometer and spectrum analyzer. The frequency range and shape of the eddy power spectra were similar to the hot-film ones but were consistently lower in magnitude. The integral length scales obtained from the power spectra agree within 30% and it was found that the average eddy size predicted the length scale obtained from the eddy produced power spectra. Successive photographs of the flow as well as the change in the eddy size distributions with distance from the grid showed evidence of eddy evolution. The results of this thesis suggest that new knowledge and understanding of the interaction of coherent structures in a turbulent fluid flow can be obtained from such flow visualization experiments. This study is part of a new model for turbulence in which the flow is described as a superposition of coherently rotating eddies and laminar flow. In this model we attempt to derive macroscopic properties of a turbulent flow from the interactions of eddies with the fluid, fluid flow and each other. The eddy size distribution can also be predicted from an understanding of the eddy interactions. The statistical description of turbulence and the often used k -power spectrum approach are reviewed and compared with our new model.
