description: Since the outbreak of Coronavirus Disease 2019 (COVID-19), most of the impacted patients have been diagnosed with high fever, dry cough, and soar throat leading to severe pneumonia. Hence, to date, the diagnosis of COVID-19 from lung imaging is proved to be a major evidence for early diagnosis of the disease. Although nucleic acid detection using real-time reverse-transcriptase polymerase chain reaction (rRT-PCR) remains a gold standard for the detection of COVID-19, the proposed approach focuses on the automated diagnosis and prognosis of the disease from a non-contrast chest computed tomography (CT)scan for timely diagnosis and triage of the patient. The prognosis covers the quantification and assessment of the disease to help hospitals with the management and planning of crucial resources, such as medical staff, ventilators and intensive care units (ICUs) capacity. The approach utilises deep learning techniques for automated quantification of the severity of COVID-19 disease via measuring the area of multiple rounded ground-glass opacities (GGO) and consolidations in the periphery (CP) of the lungs and accumulating them to form a severity score. The severity of the disease can be correlated with the medicines prescribed during the triage to assess the effectiveness of the treatment. The proposed approach shows promising results where the classification model achieved 93% accuracy on hold-out data.

description: We introduce and formalize the concept of information flux in a many-body register as the influence that the dynamics of a specific element receive from any other element of the register. By quantifying the information flux in a protocol, we can design the most appropriate initial state of the system and, noticeably, the distribution of coupling strengths among the parts of the register itself. The intuitive nature of this tool and its flexibility, which allow for easily manageable numerical approaches when analytic expressions are not straightforward, are greatly useful in interacting many-body systems such as quantum spin chains. We illustrate the use of this concept in quantum cloning and quantum state transfer and we also sketch its extension to non-unitary dynamics.

description: In this study, eight phenolic compounds were obtained from the over-ground parts of the Aconitum pendulum (A. pendulum) Busch through an efficient high-speed counter-current chromatography （HSCCC）method. First, the column chromatography for macroporous resin was used for the treatment of crude extract of over-ground parts of A. pendulum Busch. And then, 30% ethanol elution fraction was transferred to HSCCC for separation using the classic ethyl acetate, n-butanol and water system with the solvent ratio of 7:3:10. To improve parting efficiency, a mode of repeated injection was developed. Two groups of compounds existing in one HPLC peak were effectively separated by HSCCC. The results revealed that HSCCC could effectively isolate compounds with the same or similar polarity. Preparative HPLC was used to perform further purification, and then eight phenolic compounds were separated from the over-ground parts of the A. pendulum Busch for the first time. The current investigation successfully provides a reference for phytochemical research and, comprehensive development and utilization of A. pendulum Busch in the future. Furthermore, HSCCC efficiently separated compounds with similar polarity and its combination with preparative HPLC could play a great role in the separation of natural materials.

description: No abstracts are to be cited without prior reference to the author.Difficult economic conditions for New England's commercial fishing fleet have lead to a search for new resources. Federal resources have been used to subsidize exploratory trawling beyond the edge of the continental shelf by refitted New England fishing vessels. Potential targets include deepwater species of fishes, decapod crustaceans, and cephalopods. The first eight cruises of the FN CONTENDER captured 19 species of cephalopods in 13 families, including 4 octopods, 12 oegopsid squids, 1 myopsid squid, and 2 sepiolids. One additional species of oegopsid squid was collected by jigging from F/V Persercerence.

description: No abstracts are to be cited without prior reference to the author.The reproductive strategies of three benthic species of deep-sea fish from the north east Atlantic were studied : Helico/enus dactylopterus distributed between 245 and 800 m in depth, Coryphaenoides rupestris (400 to 1 500 m depth) andAlepocephalus bairdii (650 to 1 700 m depth). A 2-years sampling study (Dec 1995 -Dec 1997) allowed us to define the reproductive strategies and fecundity of females of the 3 species. i) H. dactylopterus population reproduced from March to June and specimens matured synchronously. Their annual fecundity was indeterminate, but a batch fecundity ranging from 1 212 to 20 504 oocytes per female was measured. ii) The period of reproduction for C. rupestris extended from Febnuuy to November with a maximum from May to November; individuals were asynchronous; annual fecundity was indeterminate, whereas batch fecundity was estimated between 4 078 and 68 780 oocytes per female. iii) We could not determine the precise period of reproduction for A. bairdii; however, mature fish were found throughout the year with a major spawning period from January to April and females were not synchronous; the annual fecundity was indeterminate, but a batch fec1D1dity was estimated from 458 to 7 049 oocytes per female. We noted that the deeper the habitat of the species, the longer the reproductive period and the less the females were synchronous during maturation. A Jong spawning period and asynchronism in maturation could be explained by the lack of pronounced cyclic environmental factors in the deep-sea; but assuming it as a general rule is not possible.
title: Studies towards the total synthesis of Leiodolide A

description: In 2006, Leiodolide A (12) was isolated from the marine sponge Leiodermatium sp., which was collected near Uchelbeluu Reef in Palau. Leiodolide A represents a novel class of macrocyclic secondary metabolites, containing a conjugated oxazole moiety within a 19-membered macrolide ring. The purified natural product was tested against the National Cancer Institute’s 60-cell line assay and displayed low micromolar potency against three unrelated cell lines. During characterisation, by employing coupling constant and NOE analysis in conjunction with chemical derivatisation, the absolute stereochemistry of the C15, C16, C17 and C24 positions was confidently determined. Similar analysis of the C4 and C5 stereogenic centres yielded ‘tenuous’ assignments and the remote nature of the C13 stereogenic centre prevented its assignment. This work describes the use of the DP4 structure probability methodology to predict the most likely correct diastereomer from a possible eight. The 4S5S13R diastereomer 128, disparate from the original ‘tenuous’ assignment, was assigned the highest probability and is the principal target of all synthetic work. Initial attempts towards the installation of the C4 and C5 stereogenic centres were unsuccessful but this was resolved with an efficacious application of the Evans anti-aldol methodology. Following the completion of the northern (C10 – C20) and southern (C1 – C9) fragments, the deprotection of the southern fragment could not be realised without degradation. Attempts to remedy this, by exploration of other fragment coupling methodologies, were unsuccessful. However, following the selection of appropriate protection and deprotection protocols, coupling of the key fragments was achieved and elaboration to the corresponding secoacid, required for the study of the crucial Mitsunobu macrolactonisation, represents the most advanced intermediate in a total synthesis of Leiodolide A reported to date.

description: The method of self-similar factor approximants is completed by defining the approximants of odd orders, constructed from the power series with the largest term of an odd power. It is shown that the method provides good approximations for transcendental functions. In some cases, just a few terms in a power series make it possible to reconstruct a transcendental function exactly. Numerical convergence of the factor approximants is checked for several examples. A special attention is paid to the possibility of extrapolating the behavior of functions, with arguments tending to infinity, from the related asymptotic series at small arguments. Applications of the method are thoroughly illustrated by the examples of several functions, nonlinear differential equations, and anharmonic models.

description: We study the computational strength of quantum particles (each of finite dimensionality) arranged on a line. First, we prove that it is possible to perform universal adiabatic quantum computation using a one-dimensional quantum system (with 9 states per particle). This might have practical implications for experimentalists interested in constructing an adiabatic quantum computer. Building on the same construction, but with some additional technical effort and 12 states per particle, we show that the problem of approximating the ground state energy of a system composed of a line of quantum particles is QMA-complete; QMA is a quantum analogue of NP. This is in striking contrast to the fact that the analogous classical problem, namely, one-dimensional MAX-2-SAT with nearest neighbor constraints, is in P. The proof of the QMA-completeness result requires an additional idea beyond the usual techniques in the area: Not all illegal configurations can be ruled out by local checks, so instead we rule out such illegal configurations because they would, in the future, evolve into a state which can be seen locally to be illegal. Our construction implies (assuming the quantum Church-Turing thesis and that quantum computers cannot efficiently solve QMA-complete problems) that there are one-dimensional systems which take an exponential time to relax to their ground states at any temperature, making them candidates for being one-dimensional spin glasses.

description: Recent millimeter and infrared observations have shown that gap and ring-like structures are common in both dust thermal emission and scattered-light of protoplanetary disks. We investigate the impact of the so-called Thermal Wave Instability (TWI) on the millimeter and infrared scattered-light images of disks. We perform 1+1D simulations of the TWI and confirm that the TWI operates when the disk is optically thick enough for stellar light, i.e., small-grain-to-gas mass ratio of $\gtrsim0.0001$. The mid-plane temperature varies as the waves propagate and hence gap and ring structures can be seen in both millimeter and infrared emission. The millimeter substructures can be observed even if the disk is fully optically thick since it is induced by the temperature variation, while density-induced substructures would disappear in the optically thick regime. The fractional separation between TWI-induced ring and gap is $Δr/r \sim$ 0.2-0.4 at $\sim$ 10-50 au, which is comparable to those found by ALMA. Due to the temperature variation, snow lines of volatile species move radially and multiple snow lines are observed even for a single species. The wave propagation velocity is as fast as $\sim$ 0.6 ${\rm au~yr^{-1}}$, which can be potentially detected with a multi-epoch observation with a time separation of a few years.

A study of the interaction loss of protons and deuterons in NaI

Publisher: name: University of British Columbia

description: Interaction losses in sodium iodide crystals have been directly measured for protons in the range of energies from 139 to 444 MeV and for deuterons of 277 MeV. Calculations of the expected loss were made for protons over the range 151-500 MeV using the best currently available reaction cross section data. Our experimental values are typically about 21% lower than the calculated values. The interaction loss for 277 MeV deuteron in Nal is about 8% lower than the calculated value obtained using the deuteron cross section value of Measday and Schneider. Using their calculated value of 100 MeV deuteron interaction loss as a reference point, we calculated the loss for 277 MeV deuterons and from a fit to our data we obtained the cross section for deuterons at an average energy of 188.4 MeV to be 2590 ± 180 mb, which is about 20% lower than the cross section obtained from the empirical relation that σ(d-A) is 2σ(p-A) at half the energy.

description: We construct a non-abelian extension $Γ$ of $S^1$ by $\cy 3 \times \cy 3$, and prove that $Γ$ acts freely and smoothly on $S^{5} \times S^{5}$. This gives new actions on $S^{5} \times S^{5}$ for an infinite family $\cP$ of finite 3-groups. We also show that any finite odd order subgroup of the exceptional Lie group $G_2$ admits a free smooth action on $S^{11}\times S^{11}$. This gives new actions on $S^{11}\times S^{11}$ for an infinite family $\cE $ of finite groups. We explain the significance of these families $\cP $, $\cE $ for the general existence problem, and correct some mistakes in the literature.

description: We present measurements of fluid particle accelerations in turbulent water flows between counter-rotating disks using three-dimensional Lagrangian particle tracking. By simultaneously following multiple particles with sub-Kolmogorov-time-scale temporal resolution, we measured the spatial correlation of fluid particle acceleration at Taylor microscale Reynolds numbers between 200 and 690. We also obtained indirect, non-intrusive measurements of the Eulerian pressure structure functions by integrating the acceleration correlations. Our experimental data provide strong support to the theoretical predictions of the acceleration correlations and the pressure structure function in isotropic high Reynolds number turbulence by Obukhov and Yaglom in 1951. The measured pressure structure functions display K41 scaling in the inertial range.

description: "Lightweight convolutional neural networks" is an important research topic in the field of embedded vision. To implement image recognition tasks on a resource-limited hardware platform, it is necessary to reduce the memory size and the computational cost. The contribution of this paper is stated as follows. First, we propose an algorithm to process a specific network architecture (Condensation-Net) without increasing the maximum memory storage for feature maps. The architecture for virtual feature maps saves 26.5% of memory bandwidth by calculating the results of cross-channel pooling before storing the feature map into the memory. Second, we show that cross-channel pooling can improve the accuracy of object detection tasks, such as face detection, because it increases the number of filter weights. Compared with Tiny-YOLOv2, the improvement of accuracy is 2.0% for quantized networks and 1.5% for full-precision networks when the false-positive rate is 0.1. Last but not the least, the analysis results show that the overhead to support the cross-channel pooling with the proposed hardware architecture is negligible small. The extra memory cost to support Condensation-Net is 0.2% of the total size, and the extra gate count is only 1.0% of the total size.

description: Chern-Simons AdS supergravity theories are gauge theories for the super-AdS group. These theories possess a fermionic symmetry which differs from standard supersymmetry. In this paper, we study five-dimensional Chern-Simons AdS supergravity in a Randall-Sundrum scenario with two Minkowski 3-branes. After making modifications to the D = 5 Chern-Simons AdS supergravity action and fermionic symmetry transformations, we obtain a Z_2-invariant total action S = \tilde{S}_bulk + S_brane and fermionic transformations \tildeδ_ε. While \tildeδ_ε\tilde{S}_bulk = 0, the fermionic symmetry is broken by S_brane. Our total action reduces to the original Randall-Sundrum model when \tilde{S}_bulk is restricted to its gravitational sector. We solve the Killing spinor equations for a bosonic configuration with vanishing su(N) and u(1) gauge fields.

description: Consider (for simplicity) two one-dimensional semi-infinite leads coupled to a quantum well via time dependent point interactions. In the remote past the system is decoupled, and each of its components is at thermal equilibrium. In the remote future the system is fully coupled. We define and compute the non equilibrium steady state (NESS) generated by this evolution. We show that when restricted to the subspace of absolute continuity of the fully coupled system, the state does not depend at all on the switching. Moreover, we show that the stationary charge current has the same invariant property, and derive the Landau-Lifschitz and Landauer-Buttiker formulas.

description: This doctoral thesis has a double aim: on the one hand, the analytical and descriptive bibliography of the Greek satirical almanacs printed during a period of sixty years, namely from 1872 to 1931 (Part II); on the other hand, the in-depth study of the history, the evolution and the principal characteristics of the aforementioned, particularly rich and extremely important, production (Part I). Based on the examination of hundreds of Greek almanacs and of a large number of primary archival evidence, which is combined with the indexing of a considerable part of the relevant Greek Press and with the study of the (poor) Greek and the (extensive) international secondary bibliography, I attempt to shed light on this particular category of the Greek satirical periodicals, which had not been studied to date.

description: A deep learning classifier for detecting seizures in neonates is proposed. This architecture is designed to detect seizure events from raw electroencephalogram (EEG) signals as opposed to the state-of-the-art hand engineered feature-based representation employed in traditional machine learning based solutions. The seizure detection system utilises only convolutional layers in order to process the multichannel time domain signal and is designed to exploit the large amount of weakly labelled data in the training stage. The system performance is assessed on a large database of continuous EEG recordings of 834h in duration; this is further validated on a held-out publicly available dataset and compared with two baseline SVM based systems. The developed system achieves a 56% relative improvement with respect to a feature-based state-of-the art baseline, reaching an AUC of 98.5%; this also compares favourably both in terms of performance and run-time. The effect of varying architectural parameters is thoroughly studied. The performance improvement is achieved through novel architecture design which allows more efficient usage of available training data and end-to-end optimisation from the front-end feature extraction to the back-end classification. The proposed architecture opens new avenues for the application of deep learning to neonatal EEG, where the performance becomes a function of the amount of training data with less dependency on the availability of precise clinical labels.

description: No abstracts are to be cited without prior reference to the author.Otolith formation involves rhythmical variations in the deposition and size of organic matrix fibres and carbonate crystals resulting in the formation of macroscopic and microscopic zonations. For these structures to be of use in age estimation they must be regulated by an endogenous rhythm linked to a periodic environmental cycle or synchronised to periodic events. Macroscopic zonations were considered as time-signals and first used to determine age in the XIX century (Reibisch, 1899) and have been extensively applied world wide in age determination of teleost fishes (Williams and Bedford, 197 4). The formation of opaque and translucent zones has been attributed to various factors, such as seasonal temperature variations and reproductive cycles (Dannevig, 1956; Kimura, 1984). However, the timing of formation of opaque or translucent zones often did not agree (Irie, 1960; Bagenal and Tesch, 1978). In a world. wide literature review of seasonal timing of otolith opaque zone formation (Beckman and Wilson, 1995), it was concluded that there is a general concurrent pattern of seasonal formation of opaque rings in spring and summer. However at higher latitudes of the northern hemisphere, opaque formation was later in the year and over a more extended period of time. No clear association between spawning and timing of otolith opaque zone formation was found (Beckman and Wilson, 1995).

description: No abstracts are to be cited without prior reference to the author.Most of the deep-water fisheries exploited by the Spanish fleet may be considered as a by­catch in mixed fisheries. They are related to different sea areas Sub-Areas VI, VII, XII, Divisions VIIIa,b; VIiie (Cantabrian Sea) and IXa (NW of Spain), using different gears (trawl, long-liner, gillnet). In recent years, new fisheries targeting deep-water species have been established as a result of the over-exploited state of the traditional stocks. These fisheries are mainly opportunistic and are subject to a great variability relying on the abundance; economic impprtance, season, and yields in relation to target species depletion. This review describes the deep fisheries of the North and Northeast Atlantic exploited by the Spanish fleet, gears, seasonal activity and their target species, as well as landings, by ports,· of the most important species. In addition, traditional artisanal fisheries off the Cantabrian Sea coast and the South Atlantic region of Spain targeting certain species are also described.

description: We present a unified strategy to derive Hardy-Poincaré inequalities on bounded and unbounded domains. The approach allows proving a general Hardy-Poincaré inequality from which the classical Poincaré and Hardy inequalities immediately follow. The idea also applies to the more general context of variable exponent Sobolev spaces. The argument, concise and constructive, does not require a priori knowledge of compactness results and retrieves geometric information on the best constants.

description: Urban dynamics in large metropolitan areas result from complex interactions across social, economic and political factors, including population distribution, flows of wealth and infrastructure requirements. We develop a Census-calibrated model of urban dynamics for the Greater Sydney and Melbourne areas for 2011 and 2016, highlighting the evolution of population distributions and the housing market structure in these two cities in terms of their mortgage and rent distributions. We show that there is a tendency to homophily between renters and mortgage holders: renters tend to cluster nearer commercial centres, whereas mortgagors tend to populate the outskirts of these centres. We also identify a critical threshold at which the long-term evolution of these two cities will bifurcate between a ‘sprawling’ and a ‘polycentric’ configuration, showing that both cities lie on the polycentric side of the critical point in the long-run. Importantly, there is a divergence of these centric tendencies between the renters and mortgage holders. The polycentric patterns characterizing the mortgagors are focused around commercial centres, and we show that the emergent housing patterns follow the major transport routes through the cities.

description: In order to handle modern convolutional neural networks (CNNs) efficiently, a hardware architecture of CNN inference accelerator is proposed to handle depthwise convolutions and regular convolutions, which are both essential building blocks for embedded-computer-vision algorithms. Different from related works, the proposed architecture can support filter kernels with different sizes with high flexibility since it does not require extra costs for intra-kernel parallelism, and it can generate convolution results faster than the architecture of the related works. The experimental results show the importance of supporting depthwise convolutions and dilated convolutions with the proposed hardware architecture. In addition to depthwise convolutions with large-kernels, a new structure called DDC layer, which includes the combination of depthwise convolutions and dilated convolutions, is also analyzed in this paper. For face detection, the computational costs decrease by 30%, and the model size decreases by 20% when the DDC layers are applied to the network. For image classification, the accuracy is increased by 1% by simply replacing $3 \times 3$ filters with $5 \times 5$ filters in depthwise convolutions.

description: We report on 8.4GHz Very Long Baseline Interferometry (VLBI) observations of the type II-P supernova SN2004et in the spiral galaxy NGC 6946, made on 20 February 2005 (151 days after explosion). The Very Large Array (VLA) flux density was 1.23$\pm$0.07 mJy, corresponding to an isotropic luminosity at 8.4GHz of (4.45$\pm$0.3)$\times10^{25}$ erg s$^{-1}$ Hz$^{-1}$ and a brightness temperature of (1.3$\pm$0.3)$\times10^{8}$ K. We also provide an improved source position, accurate to about 0.5 mas in each coordinate. The VLBI image shows a clear asymmetry. From model fitting of the size of the radio emission, we estimate a minimum expansion velocity of 15,700$\pm$2,000 km s$^{-1}$. This velocity is more than twice the expected mean expansion velocity estimated from a synchrotron self-absorbed emission model, thus suggesting that synchrotron self-absorption is not relevant for this supernova. With the benefit of an optical spectrum obtained 12 days after explosion, we favor an emission model which consists of two hot spots on an underlying expanding shell of width comparable to that of SN 1993J.

description: In recent years, to sustain the resource-intensive computational needs for training deep neural networks (DNNs), it is widely accepted that exploiting the parallelism in large-scale computing clusters is critical for the efficient deployments of DNN training jobs. However, existing resource schedulers for traditional computing clusters are not well suited for DNN training, which results in unsatisfactory job completion time performance. The limitations of these resource scheduling schemes motivate us to propose a new computing cluster resource scheduling framework that is able to leverage the special layered structure of DNN jobs and significantly improve their job completion times. Our contributions in this paper are three-fold: i) We develop a new resource scheduling analytical model by considering DNN's layered structure, which enables us to analytically formulate the resource scheduling optimization problem for DNN training in computing clusters; ii) Based on the proposed performance analytical model, we then develop an efficient resource scheduling algorithm based on the widely adopted parameter-server architecture using a sum-of-ratios multi-dimensional-knapsack decomposition (SMD) method to offer strong performance guarantee; iii) We conduct extensive numerical experiments to demonstrate the effectiveness of the proposed schedule algorithm and its superior performance over the state of the art.

description: In Section 1, we present a number of classical results concerning the Generalized Gamma Convolution (:GGC) variables, their Wiener-Gamma representations, and relation with the Dirichlet processes.To a GGC variable, one may associate a unique Thorin measure. Let $G$ a positive r.v. and $Γ_t(G)$ (resp. $Γ_t(1/G))$ the Generalized Gamma Convolution with Thorin measure $t$-times the law of $G$ (resp. the law of $1/G$). In Section 2, we compare the laws of $Γ_t(G)$ and $Γ_t(1/G)$.In Section 3, we present some old and some new examples of GGC variables, among which the lengths of excursions of Bessel processes straddling an independent exponential time.

description: Ricorrendo nel 2020 il 400° anno dal privilegio regio di fondazione dell’Università degli Studi di Cagliari, gli Autori hanno la duplice ambizione di dare un contributo scientifico-culturale alle celebrazioni dell’Ateneo e di valorizzare il ruolo dell’Anatomia e del suo insegnamento nella società e nelle vicende medico-sanitarie che hanno accompagnato l’evoluzione della sanità e della cultura medica a Cagliari e in Sardegna. Questo libro illustrato è composto da sette Capitoli. I primi tre, che vanno dalla protostoria ai giorni nostri, affrontano la maggior parte dei momenti storici dell'evoluzione della conoscenza e dell'insegnamento di Anatomia Umana e delle Scienze affini prodotti soprattutto nella città di Cagliari, nella sua Università e nelle sue Istituzioni Anatomiche ospedaliere.

Il Capitolo 4 è interamente dedicato ai Teatri Anatomici e alle Sale Anatomiche della città di Cagliari, luoghi prima poco conosciuti o totalmente sconosciuti: un percorso che si estende da Palazzo Belgrano, sede del Rettorato, all'Istituto Anatomico di via Porcell. Quest'ultimo, aperto nel 1922-23, è stato l'istituzione anatomica più importante di Cagliari fino al 1998.

Il Capitolo 5 delinea l'evoluzione storica dei metodi utilizzati per gli studi anatomici, dalla dissezione alla microscopia, tracciando nel contempo i legami dell’Anatomia con varie discipline filosofiche e scientifiche.

Il Capitolo 6 riassume la cronologia generale e offre una visione prosopografica della vita, del pensiero e del contesto storico-sociale delle Persone che si sono alternate nell'insegnamento di Anatomia. Oltre ai Professori, sono stati attentamente considerati anche i Settori e gli Assistenti, alcuni dei quali rinomati protagonisti del mondo scientifico internazionale.

Nel Capitolo 7, infine, si dedica ampio spazio ai mutamenti più recenti che evidenziano l'evoluzione dei metodi di indagine applicati tramite la microscopia ottica e la microscopia elettronica a trasmissione e a scansione; essi comprendono l’immunochimica, la morfometria, le colture cellulari, in un contesto accademico in continua trasformazione. Gli sviluppi degli ultimi 55 anni ci hanno permesso di scrivere pagine di storia più vicine ai nostri tempi e ricche di ricordi di luoghi, fatti e persone. Essi riguardano l'Istituto divenuto poi Dipartimento, il Corso di Dottorato, gli spazi museali in cui primeggia, per rilevanza mondiale e indiscussa bellezza delle opere, il Museo delle Cere Anatomiche. Infine uno spazio è dedicato ai Laboratori di Ricerca dell'attuale Sezione di Citomorfologia del Dipartimento di Scienze Biomediche e al loro contributo al progresso della ricerca scientifica in campo morfologico e funzionale.
Monte Carlo simulation and aspects of the magnetostatic design of the TRIUMF second arm spectrometer

description: The optical design of the TRIUMF Second Arm Spectrometer (SASP) has been completed and the engineering design started. The effects of the dipole shape and field clamps on the aperture fringe fields were studied. It was determined that a field clamp would be necessary to achieve the field specifications over the desired range of dipole excitations. A specification of the dipole pole edges and field clamps for the SASP is made. A Monte Carlo simulator for the SASP was written. During the design this was used to study the profiles of rays passing through the SASP. These profiles were used in determining the positioning of the dipole vacuum boxes and the SASP detector arrays. The simulator is intended to assess experimental arrangements of the SASP.
