Louis Sullivan: The Poetry of Architecture

This volume is both a tribute to Sullivan's poetic genius and a catalogue of all his graphic work. The authors discuss the social implications of Sullivan's theories of architecture, with visual proof of his vision in illustrations of his work on paper and in three dimensions. A translation of 'Etude sur l'inspiration,' Sullivan's seminal and heretofore unpublished credo in verse, is further testimony to his vision. Included is an illustrated catalogue of all extant Sullivan drawings, some never before published.
Análisis morfológico con OCT del daño glaucomatoso en distintos tipos de glaucoma de ángulo abierto

Estudiamos 3 tipos de Glaucoma de Angulo Abierto como son el Glaucoma Hiperbarico, el Glaucoma Focal y el Glaucoma Pseudoexfoliativo con tecnicas de diagnostico estructural mediante OCT Stratus y funcional con Perimetria Automatizada blanco-blanco. Nuestros objetivos principales fueron: -Describir las caracteristicas demograficas de los 3 grupos. -Relacionar el nivel de PIO basal con el dano perimetrico. -Analizar el dano estructural a nivel de la cabeza del nervio optico con OCT-Stratus en los 3 grupos de estudio. -Correlacionar los parametros de dano estructural con los de dano funcional en los 3 grupos de GAA. MATERIAL Y METODOS Para ello se incluyeron en el estudio 107 pacientes: 36 con G. Hiperbarico, 43 con G. Focal y 28 con G. Pseudoexfoliativo a l,os que se realizo un estudio que incluia: -Refraccion. -Tonometria tipo Goldmann -Paquimetria Ultrasonica. -Perimetria Automatizada tipo Humphrey Sita Estandar 24-2 -OCT- Stratus con pruebas RNFL Thickness y Fast Optic Disc RESULTADOS Encontrabamos diferencias estadisticamente significativas en la PIO basal de los 3 grupos (p<0,001) siendo el grupo de Hiperbaricos el de mayor presion y el de Focales el de menor PIO. Sin embargo, no encontramos diferencias significativas ni en la medida del grosor de CFNR (p=0,28) ni en los indices de dano perimetrico MD (p= 0,191) y DSM (p= 0,074). El grupo de Pseudoexfoliativos era el que mejor correlacion presentaba entre la medida de la PIO basal y los valores de MD y DSM. El grupo de Focales no presentaba ninguna correlacion. Morfologicamente, el analisis con OCT no mostraba diferencias en el tamano del area del disco entre los 3 grupos (p=0,93). El grupo de GPEX era el que presentaba mayor area y volumen del anillo (p<0,0001), no encontrandose diferencias estadisticamente significativas en el analisis de comparaciones multiples en parametros de excavacion entre los grupos extremos de presion: Focal e Hiperbarico. Desde el punto de vista de la correlacion estructura-funcion, los grupos que mejores factores de correlacion presentaban eran los de mayor presion inicial tanto con MD como con DSM pero sobre todo con la primera. CONCLUSIONES -3 grupos diferentes de GAA con distinta presion de partida no presentaron diferencias en la medida de la capa de fibras nerviosas de la retina ni en los indices significativos de dano perimetrico. -El grupo de Pseudoexfoliativos era el que presentaba mejor correlacion entre el valor de PIO inicial y los valores de los indices de dano campimetrico lo que le hace ser el grupo mas sensible al dano presion-dependiente. -El grupo de Pseudoexfoliacion era el que presentaba los mejores parametros relacionados con la medida del anillo neurorretiniano con OCT. -Los grupos de Focales e Hiperbaricos no presentaban en el analisis con OCT diferencias significativas en los parametros de excavacion de disco optico. -La correlacion entre el dano estructural y el dano funcional en los grupos de estudio fue moderada oscilando entre 0,37 y 0,73.
Analysis of the Magnetic Flux Distribution in a New Shifted Non-Segmented Grain Oriented AC Motor Magnetic Circuit

This paper deals with a new AC electric motor magnetic circuit structure made of shifted non-segmented grain oriented steel laminations. The aim of the paper is to understand with a finite element approach the local distribution of the magnetic flux density inside shifted laminations as well as in the air-gaps between them. It is shown that the air-gap flux distribution is not trivial at all and very difficult to appreciate.
Effect of Varying Rest Intervals Between Sets of Assistance Exercises on Creatine Kinase and Lactate Dehydrogenase Responses

Machado, M, Koch, AJ, Willardson, JM, Pereira, LS, Cardoso, IM, Motta, MKS, Pereira, R, and Monteiro, AN. Effect of varying rest intervals between sets of assistance exercises on creatine kinase and lactate dehydrogenase responses. J Strength Cond Res 25(5): 1339-1345, 2011-To examine the effects of different rest intervals between sets on serum creatine kinase (CK) and lactate dehydrogenase (LDH) activity, 10 men (age = 25.6 ± 2.2 years, height = 173.1 ± 7.1 cm, and body mass = 75.9 ± 10.0 kg) participated in a randomized within-subject design that involved 4 resistance exercise sessions. Each session consisted of 4 sets of 10 repetitions with 10 repetition maximum loads for the chest press, pullover, biceps curl, triceps extension, leg extension, and prone leg curl. The sessions differed only in the length of the rest interval between sets and exercises, specifically: 60, 90, 120, 180 seconds. Serum CK and LDH were significantly (p < 0.05) elevated 24-72 hours after each session, with no significant differences between rest intervals (p = 0.94 and p = 0.99, respectively). The mechanical stress imposed by the 4 resistance exercise sessions invoked similar damage to the muscle fibers independent of the rest interval between sets. These data indicate that the accumulated volume of work is the primary determinant of muscle damage in trained subjects who are accustomed to resistance exercise with short rest intervals.
Averaged stochastic gradient algorithms for adaptive blind multiuser detection in DS/CDMA systems

In this paper, we present a blind adaptive gradient (BAG) algorithm for code-aided suppression of multiple-access interference (MAI) and narrow-band interference (NBI) in direct-sequence/code-division multiple-access (DS/CDMA) systems. This BAG algorithm is based on the concept of accelerating the convergence of a stochastic gradient algorithm by averaging. This ingenious concept of averaging was invented by Polyak and Juditsky (1992)-this paper examines its application to blind multiuser detection and NBI suppression in DS/CDMA systems. We prove that BAG has identical convergence and tracking properties to recursive least squares (LMS) but has a computational cost similar to the least mean squares (LMS) algorithm-i.e., an order of magnitude lower computational cost than RLS. Simulations are used to compare our averaged gradient algorithm with the blind LMS and LMS schemes.
Construction du bi-plurilinguisme en français langue de scolarisation : apprentissage d'une L2 en enseignement bilingue précoce

Alors que l'efficacite et l'interet des dispositifs d'enseignement bilingue precoce ont ete largement demontres, peu d'etudes se sont penchees en detail sur les processus a l'oeuvre dans l'acquisition precoce d'une langue etrangere. Cette etude vise a analyser le developpement de la competence en L2 chez de jeunes enfants, dans un contexte ou l'ecole est la seule source d'exposition a celle-ci. A partir d'un corpus recueilli dans des classes de maternelle et primaire de deux ecoles franco-americaines en Californie, nous proposons d'examiner comment des enfants anglophones de 4 a 7 ans scolarises dans un dispositif de type immersif construisent leur competence en francais. En nous appuyant sur un cadre interactionniste d'acquisition de la L2, nous montrerons comment ce contexte specifique impacte le deroulement de l'acquisition, en termes d'opportunites d'interaction et d'input adresse aux enfants, et examinerons dans quelle mesure il fournit un socle aux premieres acquisitions en francais. Cette etude vise egalement a evaluer le role de l'âge dans le deroulement de l'acquisition. Nous suggerons que l'idee selon laquelle commencer l'apprentissage d'une L2 le plus jeune possible serait garant d'une meilleure maitrise de la langue n'est pas necessairement valable dans ce contexte particulier d'acquisition, tant de multiples autres facteurs sont a prendre en compte (conscience linguistique et metalinguistique, strategies d'interaction, influence de la L1). Des pistes pedagogiques sont egalement proposees a partir de ces resultats, afin de fournir quelques orientations pour l'enseignement bilingue en maternelle.
Coprocessor architecture with scaled dynamic switching activity for embedded cryptosystems

In embedded cryptosystems, sensitive information can leak via timing, power, and electromagnetic side-channels. In this paper, we introduce a new architecture for cryptographic processors that supports dynamic scaling of the switching activity as a countermeasure against side-channel attacks. The architecture is implemented using CMOSP18 technology. Simulation results based on NANOSIM and SPICE show that desynchronization of current traces is possible and the peak-to-peak variation of the current consumption of the processor is reduced. These effects result in an increased security of a system against side-channel attacks
Predictable Shared Memory Resources for Multi-Core Real-Time Systems

A major challenge in multi-core real-time systems is the interference problem on the shared hardware components amongst cores. Examples of these shared components include buses, on-chip caches, and off-chip dynamic random access memories (DRAMs). The problem arises because different cores in the system interfere with each other, while competing to access the shared hardware components. It is a challenging problem for real-time systems because operations of one core affect the temporal behaviour of other cores, which complicates the timing analysis of the system. We address this problem by making the following contributions. 1) For shared buses, we propose CArb, a predictable and criticality-aware arbiter, which provides guaranteed and differential service to tasks based on their requirements. In addition, we utilize CArb to mitigate overheads resulting from system switching among different modes. 2) For the cache hierarchy, we address the problem of maintaining cache coherence in multi-core real-time systems by modifying current coherence protocols such that data sharing is viable for real-time systems in a manner amenable for timing analysis. The proposed solution provides performance improvements, does not impose any scheduling restrictions, and does not require any source-code modifications. 3) At the shared DRAM level, we propose PMC, a programmable memory controller that provides latency guarantees for running tasks upon accessing the off-chip DRAM, while assigning differential memory services to tasks based on their bandwidth and latency requirements. In addition to PMC, we conduct a latency-based analysis on DRAM memory controllers (MCs). Our analysis provides both best-case and worst-case bounds on the latency that any request suffers upon accessing the DRAM. The analysis comprehensively covers all possible interactions of successive requests considering all possible DRAM states. Finally, we formally model request interrelations and DRAM command interactions. We use these models to develop an automated validation framework along with benchmark suites to validate and evaluate PMC and any other MC, which we release as an open-source tool.
Molecular Signature of Indeterminate Thyroid Lesions: Current Methods to Improve Fine Needle Aspiration Cytology (FNAC) Diagnosis

Fine needle aspiration cytology (FNAC) represents the gold standard for determining the nature of thyroid nodules. It is a reliable method with good sensitivity and specificity. However, indeterminate lesions remain a diagnostic challenge and researchers have contributed molecular markers to search for in cytological material to refine FNAC diagnosis and avoid unnecessary surgeries. Nowadays, several “home-made” methods as well as commercial tests are available to investigate the molecular signature of an aspirate. Moreover, other markers (i.e., microRNA, and circulating tumor cells) have been proposed to discriminate benign from malignant thyroid lesions. Here, we review the literature and provide data from our laboratory on mutational analysis of FNAC material and circulating microRNA expression obtained in the last 6 years.
Immunohistochemical evidence for the involvement of protein convertases 5A and 2 in the processing of pro‐neurotensin in rat brain

The neuropeptides/neurotransmitters neurotensin (NT) and neuromedin (NN) are synthesized by endoproteolytic cleavage of a common inactive precursor, pro‐NT/NN. In vitro studies have suggested that the prohormone convertases PC5A and PC2 might both be involved in this process. In the present study, we used dual immunohistochemical techniques to determine whether either one or both of these two convertases were co‐localized with pro‐NT/NN maturation products and could therefore be involved in the physiological processing of this propeptide in rat brain. PC2‐immunoreactive neurons were present in all regions immunopositive for NT. All but three regions expressing NT were also immunopositive for PC5A. Dual localization of NT with either convertase revealed that NT was extensively co‐localized with both PC5A and PC2, albeit with regional differences. These results strongly suggest that PC5A and PC2 may play a key role in the maturation of pro‐NT/NN in mammalian brain. The regional variability in NT/PC co‐localization patterns may account for the region‐specific maturation profiles previously reported for pro‐NT/NN. The high degree of overlap between PC5A and PC2 in most NT‐rich areas further suggests that these two convertases may act jointly to process pro‐NT/NN. At the subcellular level, PC5A was largely co‐localized with the mid‐cisternae Golgi marker MG‐160. By contrast, PC2 was almost completely excluded from MG‐160‐immunoreactive compartments. These results suggest that PC5A, which is particularly efficient at cleaving the two C‐terminal‐most dibasics of pro‐NT/NN, may be acting as early as in the Golgi apparatus to release NT, whereas PC2, which is considerably more active than PC5A in cleaving the third C‐terminal doublet, may be predominantly involved further distally along the secretory pathway to release NN.

Machine learning in control of functional electrical stimulation systems for locomotion

Two machine learning techniques were evaluated for automatic design of a rule-based control of functional electrical stimulation (FES) for locomotion of spinal cord injured humans. The task was to learn the invariant characteristics of the relationship between sensory information and the FES-control signal by using off-line supervised training. Sensory signals were recorded using pressure sensors installed in the insoles of a subject's shoes and goniometers attached across the joints of the affected leg. The FES-control consisted of pulses corresponding to time intervals when the subject pressed on the manual push-button to deliver the stimulation during FES-assisted ambulation. The machine learning techniques used were the adaptive logic network (ALN) and the inductive learning algorithm (IL). Results to date suggest that, given the same training data, the IL learned faster than the ALN while both performed the test rapidly. The generalization was estimated by measuring the test errors and it was better with an ALN, especially if past points were used to reflect the time dimension. Both techniques were able to predict future stimulation events. An advantage of the ALN over the IL was that ALN's can be retrained with new data without losing previously collected knowledge. The advantages of the IL over the ALN were that the IL produces small, explicit, comprehensible trees and that the relative importance of each sensory contribution can be quantified. <<ETX>>
Defining gluten refractory enteropathy

Objective The diagnosis of coeliac disease (CD) is based on the responsiveness of the enteropathy to a gluten-free diet (GFD). This implies that terms such as ‘non-responsive CD’ and ‘refractory CD’ are almost paradoxical. In spite of this, these terms are commonly used in the literature, often with different and confusing meanings. Methods On the basis of both a review of the literature and our clinical experience, we propose the following classification. A condition characterized by a refractory enteropathy, not due to lymphoma, ulcerative jejunoileitis or collagenous sprue, but in which gluten sensitivity has been shown previously or could be shown while the patients were on an immunosuppressive therapy should be indicated as refractory CD. Those patients in whom gluten sensitivity can be excluded should be considered to be affected by non-coeliac refractory sprue. Finally, patients in whom the presence of CD cannot be either confirmed or excluded should be considered to be affected by undefined sprue. Results Twenty-four certain refractory patients are described in the literature. The data suggest a diagnosis of refractory CD in 13 patients, non-coeliac refractory sprue in three patients, and undefined sprue in eight patients. Conclusions We define refractory CD as a form of CD that no longer responds to a GFD. Non-coeliac refractory sprue is a condition unrelated to CD. It could be either an independent condition or a common end point of different enteropathies.
Efficient Simulations Among Several Models of Parallel Computers

A parallel computer (PC) with fixed communication network is called fair if the degree of this network is bounded, otherwise it is called unfair. In a PC with predictable communication each processor can precompute the addresses of the processors it wants to communicate with in the next t steps in $O(t)$ steps. For an arbitrary $\varepsilon > 0$ we define fair PC’s M and $M'$ with $O(n^{1 + \varepsilon } )$ processors each. $M(M')$ can simulate each unfair PC with predictable communication and $O(\log (n))$ storage locations per processor (each fair PC) with n processors with constant time loss. $M'$ improves a result from [Acts Informatics, 19 (1983), pp. 269–296] where a time loss of $O(\log \log (n))$ was achieved. Assuming some reasonable properties of simulations we finally prove a lower bound $\Omega (\log (n))$ for the time loss of a fair PC which can simulate each unfair PC.

Efficient Adaptive and Dynamic Mesh Refinement Based on a Non-recursive Strategy

In this paper, we present a meshing scheme for the implementation of an adaptive tessellation of triangular meshes on the graphics processing unit (GPU). Tessellation is performed according to a local test to generate primitives dynamically. The refinement procedure does not require the pre-computation of any refinement pattern. The resulting adaptive procedure is efficient and simple, and generates the tessellation pattern of each triangle dynamically. The non-recursive strategy simplifies mesh reconstruction, avoids irregular memory access patterns and uses a simple control flow to make it a good candidate to guide the evolution of tessellation algorithms on future graphics cards. To test our proposal, we have used the geometry shader of current GPUs to generate primitives dynamically.
Tooth loss in periodontal patients.

OBJECTIVE To compare tooth loss between patients who received surgical therapy for chronic periodontitis and those who received nonsurgical therapy alone. METHODS A retrospective chart study was conducted at Dalhousie University. All patients who had periodontal treatment and were active cases for at least 10 years were included (n = 335). The sample consisted of 120 males (35.8%) and 215 females (64.2%). Ages ranged from 16 to 77 (mean = 46.1 +/- 12.0 years). All patients received nonsurgical therapy; 44.8% received periodontal surgery as well. Variables recorded were demographics, initial attachment loss, treatment type, recall frequency, patient compliance and history of extracted teeth. Independent t-tests or chi-squared tests were used to compare these for surgical and nonsurgical patients. ANOVA was used to test for interactions between initial attachment loss, age, gender, compliance and type of therapy a patient received as reasons for tooth loss. RESULTS 521 teeth were lost in 69 patients (20.6% of sample). Of teeth lost, 61.8% were due to periodontal disease; 24.8% to caries; 13.2% to other reasons. Patients initially diagnosed with early attachment loss lost an average of 0.37 (+/- 1.33) teeth. Patients diagnosed with moderate attachment loss lost an average of 1.50 (+/- 2.54) teeth and those diagnosed with advanced attachment loss lost an average of 3.11 (+/- 3.01) teeth. Those who received surgical therapy lost more teeth (mean = 1.31 +/- 2.36) than those who received nonsurgical treatment (mean = 0.68 +/- 1.87; p = 0.001). However, initial attachment loss was the only factor that could predict tooth loss. The type of therapy (surgical or nonsurgical) was not statistically significant. CONCLUSIONS Most periodontal patients (79.4%) who received treatment at this dental school clinic did not lose any teeth due to periodontal disease over at least 10 years. Although patients who had surgical therapy lost more teeth than those who had nonsurgical therapy alone, this was not an important predictor of tooth loss.
Energy management by controlling air conditioning systems in residential settings

This paper demonstrates some results from an on-going experiment on energy management in a residential testbed in Singapore by controlling the air-conditioning (AC) system. The testbed is set up at the faculty housing of Singapore University of Technology and Design (SUTD) in which the ACs installed within each unit can be controlled from a remote server. The control can be conducted both in terms of switching on/off and changing the temperature set-point of the ACs. The main objectives are to reduce the consumption of energy at a residential setting by controlling the ACs' temperature set-points and investigating the feasibility of having residential ACs as interruptible loads for demand response and thus enabling residential users to participate in the energy market. The control methodology is briefly discussed and the users' inputs on the experience of such experiments are also explained. Some preliminary results from the experiments are discussed and some insights are provided into how much load can be controlled through the set-point temperature of ACs such that the users do not feel any discomfort.
