Designing a graphics processing unit accelerated petaflop capable lattice Boltzmann solver: Read aligned data layouts and asynchronous communication
2016
The lattice Boltzmann method is a well-established numerical approach for complex fluid flow simulations. Recently, general-purpose graphics processing units (GPUs) have become available as high-performance computing resources at large scale. We report on designing and implementing a lattice Boltzmann solver for multi-GPU systems that achieves 1.79 PFLOPS performance on 16,384 GPUs. To achieve this performance, we introduce a GPU compatible version of the so-called bundle data layout and eliminate the halo sites in order to improve data access alignment. Furthermore, we make use of the possibility to overlap data transfer between the host central processing unit and the device GPU with com…
Preventing reverse engineering of native and managed programs
2015
One of the important aspects of protecting software from attack, theft of algorithms, or illegal software use is eliminating the possibility of performing reverse engineering. One common method used to deal with these issues is code obfuscation. However, it is proven to be ineffective. Code encryption is a much more effective means of defying reverse engineering, but it requires managing a cryptographic key available to none but the permissible users. The thesis presents a system for managing cryptographic keys in a protected environment and supporting execution of encrypted code. The system has strong security guarantees. In particular, the cryptographic keys are never stored on the target…
Virtudes escolares percibidas por estudiantes y docentes ecuatorianos: diferencias según sexo, establecimiento y roles
2020
El objetivo del estudio es evaluar la virtuosidad percibida en organizaciones escolares y las diferencias por tipo de centro educativo (fiscal, municipal); sexo (mujer, hombre) y rol (estudiantes, docentes). Se trató de un estudio instrumental basado en el análisis de la estructura factorial y la fiabilidad de un cuestionario para evaluar virtudes percibidas en escuelas (VPOE); y, de un estudio descriptivo transversal que analizó diferencias por sexo, rol y tipo de organizaciones escolares con relación a las virtudes percibidas. Se trabajó con una muestra de 550 estudiantes (49.28 % mujeres) y 105 docentes (47.62% mujeres). El análisis factorial determinó un modelo de cuatro factores que pe…
Atgremotāju un vides Listeria innocua izolātu ģenētiskais raksturojums un invāzijas izvērtējums in vitro.
2021
Silva Gradovska (2021): Atgremotāju klīniskā materiāla un vides Listeria innocua izolātu ģenētiskais raksturojums un invāzijas izvērtējums in vitro. Listeria ģints baktērijas ir vidē plaši sastopami mikroorganismi, no kuriem Listeria monocytogenes un L. ivanovii spēj ierosināt listeriozi. Patogenitātes ziņā mazāk pētītā L. innocua ir Gram-pozitīva vides baktērija, kas ir radniecīga L. monocytogenes. Darba mērķis bija novērtēt L. innocua izplatību vidē un raksturot to kā iespējamo patogēnu, analizējot L. innocua izolātus, kas iegūti no 27 saimniecības fermu vides un atgremotāju abortiem, genoma līmenī. Darbā visiem L. innocua izolātiem ir identificēta atsevišķu virulences gēnu klātbūtne un n…
Incidence and dynamics of active cytomegalovirus infection in allogeneic stem cell transplant patients according to single nucleotide polymorphisms i…
2014
Single nucleotide polymorphisms (SNPs) in genes involved in the activation or regulation of innate and adaptive immune responses may modulate the susceptibility to and the natural history of certain chronic viral infections. The current study aimed to investigate whether donor and recipient SNPs in the chemokine receptor 5 (rs1800023), monocyte chemoattractant protein 1 (rs13900), interleukin-10 (rs1878672), and Toll-like receptor 9 (rs352140) genes would exert any influence on the rate of incidence and features of CMV DNAemia in the allogeneic stem cell transplantation setting. This was a retrospective observational multicenter study. The cohort consisted of 102 non-consecutive allogeneic …
Revolutionary Struggle for Existence: Introduction to Four Intriguing Puzzles in Virus Research
2012
Cellular life is immersed into an ocean of viruses. Virosphere forms the shadow of this cell-based tree of life: completely dependent on the tree for existence, yet, the tree is equally unable to escape its ever evolving companion. How important role has the shadow played in the evolution of life? Is it a mere ethereal partner or a constitutive factor? In this chapter four puzzles in virus research are taken under the scope in order to probe some of the intriguing ways by which viruses can help us understand life on Earth. These puzzles consider the origin of genetic information in viruses, viruses as symbiotic partners, the structural diversity of viruses and the role of viruses in the ori…
SV40 transformed fibroblasts recognize the same 140 kD fibronectin chemotactic fragment as non-transformed cells
1985
SV40-virus-transformed human embryonal fibroblasts show an enhanced chemotactic response to the glycoprotein fibronectin. However, they recognize the same chemotactic active region as non-transformed fibroblasts. The result suggests that an enhancement of chemotaxis by fibroblasts which have been transformed with Simian Virus 40 is due not to the utilization of further chemotactic domains in the molecule, but to an increased sensitivity of the cells to the chemoattractant.
Turystyczny przewodnik po Piekle Mikołaja Reja, czyli o międzyplanetarnych podróżach duszy ludzkiej
2020
The article deals with the complex issue of presenting the underworld in the Reja's Wizerunk. The author draws attention to the presence in the output of the old Polish poet of many visionary elements borrowed from the most varied traditions and religious systems. The popular pattern of searching for spiritual perfection, fixed in the archetype of the topographic movement of the hero (Latin: Homo viator) turns out to be particularly visible. It turns out that at the very foundations of this imaginative pattern there is an ancient doctrine or interplanetary wandering of the soul. Most of the work was focused on the description of XI songs of Reja’s WizerunV, where a description of hell appea…
Event-related potentials to task-irrelevant changes in facial expressions
2009
Abstract Background Numerous previous experiments have used oddball paradigm to study change detection. This paradigm is applied here to study change detection of facial expressions in a context which demands abstraction of the emotional expression-related facial features among other changing facial features. Methods Event-related potentials (ERPs) were recorded in adult humans engaged in a demanding auditory task. In an oddball paradigm, repeated pictures of faces with a neutral expression ('standard', p = .9) were rarely replaced by pictures with a fearful ('fearful deviant', p = .05) or happy ('happy deviant', p = .05) expression. Importantly, facial identities changed from picture to pi…
